Item 1. Business.

Overview

Response Genetics, Inc. (the “Company”) was formed as a Delaware corporation in September 1999. We are a life sciences company engaged in the research and development of clinical diagnostic tests for cancer. Our mission is to provide personalized genetic information that will help guide physicians and patients in choosing the treatment from which a given patient is most likely to benefit. We currently generate revenues primarily from sales of our ResponseDX ^® diagnostic tests, which we launched in 2008, and by providing clinical trial testing services to pharmaceutical companies.

Our proprietary technologies enable us to reliably and consistently extract ribonucleic acid (“RNA”) and deoxyribonucleic acid (“DNA”) from tumor specimens that are stored as formalin-fixed and paraffin-embedded (“FFPE”) specimens and thereby to analyze genetic information contained in these tissues. Our technologies also enable us to use the FFPE patient biopsies for the development of diagnostic tests.

We file our annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, amendments to those reports and other information with the Securities and Exchange Commission (the “SEC”). Copies of these reports are also available through our website at www.responsegenetics.com. We also post copies of our press releases on our corporate website.

Our Approach

Clinical studies have shown that not all cancer therapy works effectively in every patient, and that a number of patients receive therapy that has no benefit to them and may potentially even be harmful. Our goal is to provide cancer patients and their physicians with a means to make informed, individualized treatment decisions based on genetic analyses of tumor tissues. We are focusing our efforts in the following areas:

Continued commercialization of our ResponseDX ^® tests;

Broadening our offerings with the introduction of the former Pathwork Diagnostics Tissue of Origin test that was acquired when we purchased the Pathwork Diagnostics assets in August of 2013;

Enhancing our capabilities in the way we deliver our services to oncologists and pathologists. In late 2013, the Company introduced its TC/PC system to competitively offer its services to pathologists;

Developing additional diagnostic tests for predicting therapy response and determining the diagnosis and prognosis of solid tumors in cancer patients;

Expanding our testing services business by pursuing new technologies through collaborations and in-licensing to expand our business; and

Selectively building our pharmaceutical services business.

Our technologies enable us to reliably and consistently extract the nucleic acids, ribonucleic acid (“RNA”) and deoxyribonucleic acid (“DNA”), from tumor specimens that are stored as formalin-fixed and paraffin-embedded specimens and thereby to analyze genetic information contained in these tissues. This is significant because the majority of patients diagnosed with cancer have a tumor biopsy sample stored in paraffin, while only a small percentage of patients’ tumor specimens are frozen. Our technologies also enable us to use the FFPE patient biopsies for the development of new diagnostic tests.

ResponseDX ^®

The outcome of cancer therapy is highly variable due to genetic differences among the tumors in cancer patients. Some patients respond well with tumor shrinkage and increase in life span. Other patients do not obtain benefit from the same therapy and may actually experience toxic side effects, psychological trauma and delay in effective treatment.

Until recently, most cancer treatment regimens were administered without any pre-selection of patients on the basis of the particular genetics of their tumor. However, advances in molecular technologies have enabled researchers to identify and measure genetic factors in patients’ tumors that may predict the probability of success or failure of many anti-cancer agents. In order to increase the chances of a better outcome for cancer patients, we offer and continue to expand our offering of tests for measuring predictive factors for therapy response in tumor tissue samples. We provide tests for non-small cell lung cancer (“NSCLC”), colorectal cancer (“CRC”), gastric and gastroesophageal cancer (“GE”), melanoma and thyroid cancer, and breast cancer patients’ tumor tissue specimens through our ResponseDX: Lung ^® , ResponseDX: Colon ^® , ResponseDX: Gastric ^® , ResponseDX: Melanoma ^® , ResponseDX: Thyroid ^TM and ResponseDX: Breast ^TM test suites at our laboratory located in Los Angeles, California, which is certified under the Clinical Laboratory Improvement Amendments of 1988 (“CLIA”). These tests serve to help oncologists make optimal therapeutic decisions for cancer patients. The results from our tests may help oncologists choose among therapies to treat their cancer patients.

In August 2013, the Company acquired substantially all of the assets of Pathwork Diagnostics, Inc. including its FDA-cleared Tissue of Origin cancer test. This newly acquired test was launched commercially by the Company in February 2014 as the ResponseDX: Tissue of Origin ^TM test. The ResponseDX: Tissue of Origin ^TM test is a microarray-based gene expression test that aids in identifying challenging tumors, including metastatic, poorly differentiated, and undifferentiated cancers. The ResponseDX: Tissue of Origin ^TM test uses a proprietary microarray platform and proprietary software to compare the expression of 2,000 genes in a patient's tumor with a panel of 15 known tumor types that represent 90% of all cancers. The test received FDA clearance in June 2010.

As of December 31, 2013, our ResponseDX ^® sales team, including the management thereof, consisted of 21 members located in the West, Southeast, and Northeast areas of the United States.

Tests Launched

During 2013, we added four additional tests to our ResponseDX ^® offering: HER2 mutation detection, KIT mutation detection, MET FISH and UGT1A1 SNP. In addition, we expanded our suite of profiles to include ResponseDX: Thyroid ^TM .

HER2 Mutation Detection

In September of 2013, we launched testing for HER2 mutations in non-small cell lung cancer (“NSCLC”). Activating mutations within the tyrosine kinase domain of the HER2 gene exist within a subset of NSCLC patients, and recent clinical studies suggest that NSCLC patients carrying these mutations may benefit from HER2-targeting therapies such as trastuzumab and afatinib. Our Sanger sequencing based HER2 mutation detection test can be performed for patients for whom we have stored a residual nucleic acid sample. We believe the Company was the first commercial organization to offer HER2 mutation detection testing for lung cancer.

cKIT Mutation Detection

In September of 2013, we also began offering cKIT mutation detection in our ResponseDX: Melanoma ^® and ResponseDX: Gastric ^® panels. The Company’s cKIT assay is a Sanger sequencing based test aimed to identify cKIT mutations, which are believed to be a major oncogenic event in melanoma and gastrointestinal stromal tumors (“GIST”). Imatinib (Gleevec®), an oral tyrosine kinase inhibitor initially developed for treatment of chronic myelogenous leukemia, has been shown to inhibit cKIT. Mutations in cKIT have been proven to be predictive of response to imatinib and other drugs for both GIST and melanoma. Sunitinib, another tyrosine kinase inhibitor that targets cKIT, is approved for use with imatinib-resistant GIST, among other tumor types.

MET gene amplification (FISH)

Amplification of MET is associated with poor patient prognosis in NSCLC, brain, breast, colorectal, gastric, and head and neck carcinomas, and associated with resistance to radiotherapy in NSCLC patients and with resistance to anti-EGFR therapies in both colorectal and lung carcinomas. In addition, the most recent National Comprehensive Cancer Network (“NCCN”) guidelines for NSCLC recognize MET amplification as a driver event in NSCLC for which a targeted agent (crizotinib) is available. In September 2013, the Company introduced a FISH test for MET gene amplification which replaces our previous RNA expression assay for cMET.

UGT1A1 Test

In September, 2013, we added UGT1A1 testing to our ResponseDX: Colon® panel. UGT1A1 is the primary enzyme for the clearance of the chemotherapy drug irinotecan, which is administered to metastatic colorectal cancer (“CRC”) patients. Certain polymorphisms in the UGT1A1 gene are associated with increased potential for adverse clinical outcomes upon treatment with irinotecan, including neutropenia and elevated levels of diarrhea, and the U.S. Food and Drug Administration (“FDA”) provides guidelines on prescribing irinotecan based on UGT1A1 genotyping prior to therapy. Response Genetics’ UGT1A1 test was developed and validated for FFPE tissue so that it could be performed on the same sample type and contemporaneously with the other analyses for molecularly targeted therapy that the Company offers for CRC.

During 2012, we added five additional tests to our ResponseDX ^® offering: ROS1 FISH, ROS1 RT-PCR, c-MET, HER2 FISH and VEGFR2. In addition, we made our NRAS assay available to our ResponseDX: Melanoma ^® offering after publications showed that NRAS mutational status may be predictive for BRAF inhibitor response in metastatic melanoma patients.

Methodologies used in Our Testing Services

PCR

A number of our tests are based on the polymerase chain reaction (“PCR”), which is a sensitive, precise and reliable technology that gives numerical values that are not dependent on subjective interpretations. We developed and extensively validated technology to perform quantitative PCR analysis of gene expressions in formalin-fixed paraffin embedded (“FFPE”) tumor tissues. We have used our technological expertise in many projects for the pharmaceutical industry and for many collaborative scientific studies. The benefit of our capability for patients is that in many cases, no tissue samples other than the pre-treatment diagnostic are required for biomarker analysis.

FISH

Our laboratory offers Fluorescence in situ hybridization (“FISH”) technology tests, which may be used to determine whether specific genes, loci or regions are present or if deletions, duplications, amplifications or other structural rearrangements have occurred.

Tech-Only FISH Service Launched

In August of 2013, we launched a partnership program with our pathology clients who wish to analyze and report the results of FISH tests. The program has as its centerpiece a state-of-the-art fluorescence slide scanning system that converts stained FISH slides into high-resolution digitized images that can be interrogated as deeply and intuitively as through traditional microscopy. The scanning system is interfaced with the Company’s portal that clients use to access testing status and reports for their patients. Pathologists who participate in our program are able to perform the professional component (“PC”) of FISH tests, provide the results of those analyses on customized reports, and bill for that service after the Company provides the technical component (“TC”) of each test.

The program was designed with maximum flexibility for participating pathologists to use it for the tests and/or cases of their choice, including both translocation and amplification tests. The Company also continues to provide “global” (both TC and PC) FISH services, and our partner pathologists can select from these options as best fits their preferences. At the inception of the program in 2013, four tests were included (ALK, ROS1, HER2, MET); we recently added RET and FGFR1, which we believe make our Tech-Only FISH offering the broadest in the industry for solid tumor testing.

Sequencing

Our laboratory also offers DNA sequencing, which is the process of determining the nucleotide order of a given DNA fragment. Currently, our validated methodology uses the chain termination method (Sanger Method), which uses sequence specific termination of a DNA synthesis reaction using modified nucleotide substrates.

Our Technologies

We utilize proprietary technologies for the extraction of RNA from FFPE tissues which enable us to reliably recover RNA suitable for a variety of applications, such as gene expression research, development of diagnostics, and microarray platforms. In addition, our technologies permit gene profiling analysis of current clinical trials, most of which use the paraffin embedding technique for tissue specimen storage.

The Company developed extraction methodologies that allow reliable and consistent isolation of RNA and DNA from FFPE suitable for use in various types of analysis. We validated our methodology, which particularly addressed issues of recovery of RNA, accuracy, and precision. Further, our methodologies allow for rapid extraction of RNA with little or no DNA contamination, which makes it suitable for large-scale analysis.

• Micro-dissection of each specimen to separate tumor from non-tumor tissue . Most tumor biopsy specimens are mixtures of normal and tumor tissue. A specimen may include only a small percentage of tumor cells. The molecular biology of tumor and normal tissues may be considerably different and mixing the two may yield false results for gene expression profiling and false negative results for mutation detection due to the diluting effect of normal cells relative to tumor cells. To accurately measure gene expression and establish expression profiles of various pathologic lesions, it is important to analyze RNA from tumor cells. With the assistance of a pathologist, we can identify the tumor cells and isolate them. Moreover, our procedure for tumor cell enrichment enables greater assay sensitivity relative to standard methods.

• Isolation of DNA from the same specimen used to obtain RNA. Alterations in DNA sequence that are inherited (polymorphisms) as well as acquired (mutations) are often associated with disease susceptibilities, treatment response, and survival. DNA polymorphisms and mutations may change the gene expression pattern of a cell in specific ways. Characterization of gene expression profiles associated with various DNA sequence alterations may lead to a better understanding of disease mechanisms and may suggest new and better treatments. Our technique for isolating DNA and RNA from the same specimen facilitates such efforts because in many cases the amount of available tissue may not be sufficient for separate isolation of DNA and RNA. In addition, measuring gene expressions and DNA sequence alteration in the same cells rather than in different areas of the tissue specimen is likely to give more valid data.

We believe these technologies may be used as a powerful tool to establish diagnostic gene sets for predicting a patient’s likelihood of survival under a particular treatment regimen. Such diagnostic tests will provide the opportunity for choosing the best treatment prior to therapy and thus enable application of personalized medicine based on each person’s unique genetics.

ResponseDX: Lung ^® , ResponseDX: Colon ^® , ResponseDX: Gastric ^® , ResponseDX: Melanoma ^® , ResponseDX: Thyroid ^TM and ResponseDX: Breast ^TM

We developed ResponseDX ^® in part by using our technology to extract genetic information from FFPE tumor specimens. Our technology provides gene expression, mutation detection and gene amplification/rearrangement information for each patient’s tumor tissue specimen. Our mission is to help doctors and patients choose the most effective cancer treatment options- the first time- based on genetic information from the patient’s tumor biopsy.

ResponseDX: Lung ^® comprises tests grouped into “Driver”, “Expanded Driver” and “Academic” profiles. The Driver profile includes: EGFR mutational analysis, ALK FISH, and ROS1 FISH. The Expanded Driver profile includes the tests in the Driver profile plus BRAF, RET (FISH), MET (FISH) and HER2 mutational analysis. The Academic profile includes the tests in the Expanded Driver profile plus ERCC1 expression, RRM1 expression, TS expression, c-Met expression, PI3 Kinase mutational analysis and FGFR1 (FISH). In addition, the Company also offers RT-PCR tests for EML4-ALK and ROS1 for customers who wish to order them instead of their FISH counterparts.

ResponseDX: Colon ^® comprises eleven tests grouped into a “Driver” profile and an “Academic” profile. The Driver profile includes: KRAS mutational analysis, BRAF mutational analysis, and MSI. The Academic profile includes the tests in the Driver profile plus ERCC1 expression, NRAS mutational analysis, PI3 Kinase mutational analysis, EGFR expression, TS expression, MET FISH, VEGFR2 expression, and UGT1A1.

ResponseDX: Gastric ^® comprises four tests: ERCC1 expression, TS expression, cKIT and HER2 amplification.

ResponseDX: Melanoma ^® comprises BRAF mutational analysis, cKIT and NRAS mutational analysis.

ResponseDX: Thyroid ^TM comprises: BRAF, RET (FISH), KRAS and NRAS.

ResponseDX: Breast ^TM comprises: HER2 (FISH), ER (IHC) and PR (IHC).

Furthermore, EGFR, KRAS, BRAF, PI3 Kinase and HER2 mutation, HER2amplification, cKIT, cKIT, NRAS, RET (FISH) and MET (FISH) can be analyzed in various other tumor types. Therefore, we are also offering these tests in other tumor types. Physicians are ordering our tests to also determine whether patients may benefit from a clinical trial of a new agent.

We have developed assays for the targets comprising the ResponseDX ^® profiles for use in our CLIA lab. Assay development of these tests was done through appropriate validation procedures which determine the accuracy, sensitivity, specificity and other characteristics of each test. Our experience in this area allows us to continue to develop additional tests for these and other ResponseDX ^® profiles.

Sales, Marketing and Client Services for ResponseDX ^® tests

We offer our ResponseDX ^® testing services nationwide. Our primary sales market includes community based oncologists, pathologists, physician offices and hospitals. Selling diagnostic testing services of cancer requires a knowledgeable and skilled sales force that can help oncologists and pathologists understand the value of our testing services. Our sales representatives generally have previous sales experience in the oncology field, including pharmaceutical sales experience, medical diagnostic services market, or laboratory services market and have knowledge of community-based hospitals and oncology practices. Our sales force is compensated through a combination of salaries, commissions based upon actual sales performance and incentives from time to time, all at levels commensurate with each individual’s qualifications, performance and responsibilities.

As of December 31, 2013, our sales team was comprised of 21 members including our Vice President of Sales. Our sales force is organized into three regions. We have a Regional Sales Director in each region that trains, develops sales territories and supports the account executives in his or her region. We will continue to develop our sales team as appropriate. Our sales strategy focuses on expanding the ResponseDX ^® testing services while acquiring new customers. Our sales approach is designed to understand our current and potential customers’ needs and to provide the appropriate solutions from our expanding range of diagnostic services.

We have developed a set of marketing materials to support our sales efforts. Our marketing materials provide a summary of our tests along with practical information regarding how to order our tests. When creating our marketing materials we have focused on establishing a distinctive corporate brand and plan on continuing to build upon our strong ResponseDX ^® brand.

We compete largely on the basis of the quality of our tests, our turnaround time, the convenience of ordering our tests and the innovation of our services.

Our Strategy

Research & Development

Research and development is crucial to the Company’s development as we seek to expand our series of diagnostic tests for cancer patients. Our research and development expenses were $2,128,610 and $1,606,662 for the years ended December 31, 2012 and 2013, respectively, representing 11.4% and 8.1% of our total operating expenses for the years ended December 31, 2012 and 2013, respectively. Major components of our research and development expenses include supplies and reagents for our research activities, personnel costs, occupancy costs, equipment warranties and service, patent fees, insurance, business consulting and sample procurement costs. We expect research and development expenses to increase as we work to develop additional aspects of our technology and to study diagnostic indicators for various forms of cancer. The following section contains further information regarding our research and development strategy and goals.

Expansion of our ResponseDX ^® diagnostic test panels

Our research and development activities primarily relate to the development and validation of diagnostic tests in connection with our ResponseDX ^® diagnostic services. In 2014, we plan to build out our product offering to include a Response DX ^® Glioma profile as well as additional tests in our existing panels.

Addition of Next-Generation Sequencing to our suite of technologies

The Company is pursuing mutational analysis by next-generation sequencing (“NGS”) to complement our suite of molecular diagnostics platforms for the analysis of cancer specimens. We plan to use NGS to detect genomic changes from FFPE tissue samples and to provide physicians with reports that are comprehensive with respect to clinically actionable alterations.

Pursue Additional Collaborations and In-licensing to Expand Our Business

We intend to pursue additional collaborations with pharmaceutical companies or in-licensing of products or technologies that will enable us to accelerate the implementation of our plans to expand the services we provide to oncologists and pathologists. We expect to implement this plan by way of licensing of technology and know-how, investments in other companies, strategic collaborations, and other similar transactions. We expect these collaborations to provide us with early access to new technologies available for commercialization.

Providing Accurate and High Quality Results - Quality Assurance Program

The quality of our diagnostic testing services is important to us and our clients. In order to deliver accurate and high quality results, we have established a quality management system in compliance with regulations and standards such as those set by the College of American Pathologists (“CAP”), the Clinical Laboratory Improvement Amendments of 1988 (“CLIA”), Good Clinical Laboratory Practices (“GCLP”), and Good Laboratory Practice (“GLP”) for our laboratory operations. This program is designed to utilize both external and internal resources to monitor the quality of our laboratory operations. For example, we participate in external quality surveillance programs, including ongoing proficiency testing programs administered CAP. CAP is an independent, non-governmental organization of board-certified pathologists which accredits, on a voluntary basis, laboratories. CAP has been deemed by the Centers for Medicare and Medicaid Services (“CMS”), which is charged with administering CLIA, as an accrediting agency to inspect clinical laboratories to determine adherence to the standards of CLIA. Our most recent CAP inspection was successfully completed in August of 2012.

License Agreement with the University of Southern California (“USC”)

In April 2000, as amended in June 2002 and April 2005, we entered into a license agreement with USC, pursuant to which USC granted us a worldwide, exclusive license with the right to sublicense, the patents for nucleic acid extraction methodologies (“RGI-1”) and related technology, for use in human and veterinary diagnostic laboratory services, the sale of clinical diagnostic products, and the sale of research products to the research community. We are obligated under the agreement to use best efforts to work toward the commercialization of the licensed technology. USC retains the right under the agreement to use the technology for research and educational purposes. In consideration for this license, we agreed to pay USC royalties based on a percentage of net sales of products or services that make use of RGI-1 and related technology, and to meet a certain minimum in royalty payments. Royalty expense, included in the cost of revenue section of the accompanying consolidated statement of operations, for the years ended December 31, 2012 and 2013 was $332,504 and $305,616, respectively .

Upon authorization from us, USC has the obligation to undertake all responsibilities for the filing, prosecution and maintenance of all patents covered under the license; however, we have agreed to reimburse USC for all associated costs. If we elect not to pursue a particular patent, the rights to that patent revert to USC, if USC takes the necessary steps to prosecute and maintain the patent; if USC does not undertake such actions, the exclusive license rights to the patent remain with us. We bear full responsibility for enforcement of patent rights against all claims of infringement by third parties and the right, but not the obligation to bring action against any alleged infringement of the licensed patents by third parties, bearing all costs. USC has the right to pursue any offensive enforcement we choose not to pursue at its own expense and we may agree with USC to pursue such action jointly, sharing all related costs.

This agreement terminates on the first to occur of: (i) the date of the expiration of the last to expire of the patents issued in any country, or (ii) if no patents issue, the date on which any decision or determination to reject or deny the last remaining patent application or claim becomes final. Either party may terminate this agreement for uncured material breach or default upon written notice to the other party. We may terminate the agreement for any reason, upon written notice to USC. USC may terminate the agreement, upon written notice, in the event that we transfer or assign our rights and obligations under the agreement to a third party, in any manner contrary to the terms of the agreement or in derogation of USC’s proprietary rights; and immediately if we fail to obtain or maintain insurance coverage and for other specified causes. We are obligated to indemnify USC against all liabilities to third parties, from claims arising in connection with the agreement and our use, sale or other distribution of services and products involving the licensed technology. We also are required to maintain comprehensive general liability insurance, appropriately covering the full scope and range of activities we pursue with the licensed technology.

Patent License Agreement with Roche Molecular Systems, Inc. (“Roche”)

In November 2004, we entered into an agreement with Roche pursuant to which we obtained a royalty-bearing, non-exclusive, personal, non-transferable license to use certain technology, including specified nucleic acid amplification processes (“PCR Processes”), to perform certain human invitro clinical laboratory services.

Roche retains all proprietary rights to the licensed technologies and our non-exclusive license is limited to the use of the technology as described above. Under this agreement, neither party is obligated to defend any proprietary rights against third parties for infringement. In consideration for this license, we are obligated to pay royalties to Roche, based on a percentage of net sales of products or services that make use of the PRC Processes. Royalty expense relating to this agreement, included in the cost in revenue section of the accompanying consolidated statement of operations, amounted to $336,285 and $280,325 for the years ended December 31, 2012 and 2013, respectively.

This agreement terminates on the date of expiration of the last to expire of the patents included in the licensed technology. Roche may immediately terminate the agreement upon written notice in the event of any material change in our ownership or control, or in the event that we breach certain non-assignability provisions of the agreement. Roche may also terminate the agreement upon prior written notice in the event of any breach or default by us of a material term under the agreement. The agreement will automatically terminate upon our entry into bankruptcy or similar proceedings.

Services Agreement with Taiho Pharmaceutical Co., Ltd. (“Taiho”)

In July 2001, the Company entered into an agreement with Taiho pursuant to which the Company provides Taiho with RGI-1 generated molecular-based tumor analyses for use in guiding chemotherapy treatment for cancer patients and for use in Taiho’s business of developing and marketing pharmaceutical and diagnostic products for use against cancer. Pursuant to the agreement, as amended, the Company appointed Taiho as the exclusive purchaser in Japan of tests and testing services based upon the RGI-1 using gene expression through 2010 for: (i) any one or the combination of specified molecular markers, (ii) the therapeutic use of specified compounds, or (iii) the diagnosis or therapeutic treatment of specified precancerous and cancerous diseases. The Company also granted Taiho the right to be a non-exclusive purchaser in Japan of tests and testing services based upon the RGI-1 using gene expression, other than those for which Taiho has exclusivity, for: (i) any one or combination of molecular markers, (ii) the therapeutic use of any compound or biological product against cancer, or (iii) the diagnosis or therapeutic treatment of precancerous and cancerous diseases.

The Company and Taiho entered into an amendment to the agreement effective January 1, 2013 that extended the term through December 31, 2013. Under the amended agreement, the Company received a minimum aggregate of $950,000 for testing services provided to Taiho in Japan on a non-exclusive basis from January 1 to December 31, 2013. Revenue recognized under this agreement for the years ended December 31, 2012 and 2013 was $1,193,425 and $950,000, respectively.

Services Agreement with GlaxoSmithKline, LLC formerly known as SmithKline Beecham Corporation (d.b.a. GlaxoSmithKline) (“GSK”)

In January 2006, the Company entered into a master services agreement with GSK, a leading pharmaceutical manufacturer, pursuant to which the Company provides services in connection with profiling the expression of various genes from a range of human cancers. Under the agreement, the Company will provide GSK with testing services as described in individual protocols and GSK pays the Company for such services based on the pricing schedule established for each particular protocol. GSK is obligated to make minimum annual payments to the Company under the agreement and also was obligated to make a non-refundable upfront payment to the Company, to be credited against work undertaken pursuant to the agreement. The timing of the recognition of these amounts is dependent upon when GSK submits the specimens for testing. In December 2008, the Company amended and restated its master services agreement with GSK and extended the term of the agreement for a two-year period, with the option for the parties to extend the agreement for additional one-year periods at the end of the term, upon their mutual written agreement. In addition, we became a preferred provider to GSK and its affiliates of genetic testing services on a fee-for-service basis and, in anticipation of the services to be provided, GSK agreed to make a non-refundable upfront payment.

The Company recognized revenue of $1,280,704 and $1,134,366 relating to the GSK agreement for the years ended December 30, 2012 and 2013, respectively.

Non-Exclusive License Agreement with GSK

In March 2010, the Company entered into a non-exclusive license agreement with GSK. Under the agreement, the Company granted GSK a non-exclusive, sublicenseable license to its proprietary PCR analysis technology and diagnostic expertise to assess BRAF gene mutations in human tumor samples. As part of the agreement, the Company received a non-refundable technology access fee in consideration for the transfer of the Company’s technology to GSK. The agreement also contains milestone provisions which allow the Company to earn up to three further payments from GSK for activities solely performed by GSK (all of which have been earned as of December 31, 2013). During the third quarter of 2012, the Company earned and recorded as revenue the first $500,000 milestone payment from GSK. In May 2013, the Company earned and recorded as revenue the second milestone payment under the agreement of $500,000. In December 2013, the Company earned and recorded as revenue the third and final $500,000 milestone payment under the terms of the agreement. The aggregate of $1.5 million of milestone payments are included in the GSK agreement revenue discussed above.

Master Services Agreement with GlaxoSmithKline Biologicals S.A. (“GSK Bio”)

In July 2012, the Company entered into a second amended and restated master services agreement with GSK Bio, the vaccine division of GSK. Pursuant to this agreement, which has an effective date of May 15, 2012, the Company provides testing services for clinical trials and epidemiology studies relating to GSK Bio’s cancer immunotherapies. The Company performs these testing services on a fee-for-service basis as embodied in written task orders. GSK Bio retains the intellectual property rights to inventions, improvements and data resulting from the services performed under the Agreement. The Company retains all intellectual property rights to its testing services, proprietary processes and all accompanying patent information owned by the Company. All intellectual property owned by either party on the date of the Agreement remains the exclusive property of the owning party.

The Agreement will expire on December 31, 2014, provided that any outstanding task orders at the time of termination will not thereby terminate (unless otherwise agreed in writing by the parties), and any such task orders will continue for the respective terms specified in such task orders (and the parties shall continue to perform their obligations thereunder). GSK Bio may terminate the Agreement, without cause, upon 90 days’ written notice to the Company. The Company may terminate the Agreement, without cause, upon one year’s written notice to GSK Bio. The Agreement may also be terminated early if either party enters bankruptcy or similar proceedings or in the event of a material breach. GSK Bio may terminate the Agreement immediately if the Company experiences a “change of control,” as defined in the Agreement.

The Agreement also provides for mutual indemnification by the parties and contains customary representations, warranties and covenants, including covenants governing the parties’ use of confidential information and representations regarding adequate insurance coverage or self-insurance.

The Company recognized revenue of $3,241,211 and $3,534,619 relating to the services performed for GSK Bio for the years ended December 31, 2012 and 2013, respectively.

GSK and GSK Bio are significant customers that together constitute more than 10% of the Company’s revenue.

Collaboration Agreement with Shanghai BioChip Company, Ltd. (“SBC”)

In March 2007, the Company entered into a collaboration agreement with SBC pursuant to which SBC provides exclusive pharmacogenomic testing services to the Company’s clients in China.

Pursuant to the agreement, the Company has granted SBC an exclusive license in China to provide services in China using the Company’s proprietary RNA extraction technologies. Subject to consent from USC, the Company granted SBC an exclusive sublicense to patents licensed from USC for distribution of testing services in China. In turn, SBC performs RNA extraction from formalin-fixed paraffin-embedded (“FFPE”) tissue specimens exclusively for the Company during the term of the agreement.

	9

This agreement had an initial term of five years, with an automatic renewal for an additional three-year term unless either party gives 90 days’ notice in advance of the renewal date of its intent not to renew. As neither party gave notice of intent not to renew, the agreement has automatically renewed for a successive three year period. Pursuant to the agreement, SBC receives a percentage of the gross margin, as defined in the agreement, collected from the Company’s clients in China as compensation for its testing services performed. For the years ended December 31, 2012 and 2013, testing services totaled $15,355 and $35,027, respectively.

Commission Agreement with Hitachi Chemical Co., Ltd. (“Hitachi”)

On July 26, 2007, the Company entered into a collaboration agreement with Hitachi, a leading diagnostics manufacturer in Japan. Under the terms of this agreement, Hitachi used the Company's proprietary and patented techniques to extract genetic information from formalin-fixed paraffin-embedded (“FFPE”) tissue samples collected in Southeast Asia, Australia and New Zealand. As part of this collaboration agreement, the Company provided Hitachi with the technical information and assistance necessary to perform the testing services. Hitachi was responsible for expenses related to the cost of laboratory equipment and modification to the laboratory facilities, as well as the cost of reagents. The Southeast Asian countries covered under this agreement include Japan, North Korea, South Korea, Taiwan, Mongolia, Pakistan, Bangladesh, Sri Lanka, Nepal, Singapore, Malaysia, Indonesia, Brunei, Thailand, Myanmar, Laos, Cambodia, Vietnam and the Philippines (the “Territory”).

The collaboration agreement had an initial term expiring on June 30, 2010, with an automatic renewal for one year at the end of the original period under the same terms and conditions. Pursuant to the agreement, Hitachi performed certain testing services and received a percentage of the revenue collected from the Company's clients in the Territory which totaled $526,823 and $0 for the years ended December 31, 2012 and 2013, respectively. Due to the closing of Hitachi’s applicable facility in the Territory, the Company and Hitachi agreed to terminate this agreement effective September 30, 2012.

Intellectual Property

We rely on a combination of patents, trade secret, copyright and trademark laws, license agreements, nondisclosure and other contractual provisions and technical measures to protect our intellectual property rights in our products, technology and processes. We have proprietary rights in several areas as further described below.

First, we exclusively license from USC the use of the RGI-1 extraction methodologies and related technologies, which have been patented in the United States and a number of other jurisdictions, including Australia, Austria, Belgium, Canada, China, Denmark, France, Germany, Hong Kong, Ireland, Israel, Italy, Luxembourg, Mexico, The Netherlands, Norway, Russia, South Korea, Spain, Sweden, Switzerland and the United Kingdom. Currently, this exclusive license includes seven United States patents claiming methods related to this technology. We use these proprietary methods when meeting our contractual obligations with various clients and when developing diagnostic tests for cancer. Our USC licensed patents are scheduled to expire between December 2019 and December 2020.

In addition, we maintain a non-exclusive license to use certain of Roche’s PCR, homogenous PCR and reverse transcription PCR processes. The Roche licensed patents which are still active in the United States began expiring in October 2013 and expire through October 2017.

Next, we have identified and are in the process of identifying tumor response markers, which provide an indication of an anti-cancer drug’s effectiveness or ineffectiveness based upon the level of such determinant in a particular tumor. We intend to protect these proprietary developments to the extent allowable under current law. We have obtained patents claiming methods and products and have patent applications pending that claim methods and products related to certain tumor response markers in the United States and in a number of other jurisdictions, including Australia, Austria, Belgium, Canada, France, Germany, Hong Kong, Ireland, Italy, Japan, Korea, Liechtenstein, The Netherlands, New Zealand, Spain, Sweden, Switzerland, Taiwan and the United Kingdom. We hold issued patents relating to tumor response markers which run until 2021 to 2024, and hold pending patent applications filed in 2001, 2002 or as recently as 2012. For example, we have patented methods related to quantifying expression of response markers from tumor tissue, which provide guidance in determining appropriate chemotherapeutic regimens for patients that are candidates for treatment with particular chemotherapies. Currently, we have fourteen United States patents that relate to certain aspects of our proprietary technology as it applies to certain tumor markers. Such markers include thymidylate synthase (TS), dihydropyrimidine dehydrogenase (DPD), excision repair gene CC1 (ERCC1), glutathione-s transferase pi (GST-p), epidermal growth factor receptor (EGFR) and HER2/neu gene, though our patents are not directed to all aspects of expression of such markers and may not preclude competition from others concerning such markers. We use some of our patented methods in fulfilling certain of our contractual obligations with various clients. We have also licensed the use of our patents related to certain markers and technology know-how to GSK.

Finally, we have proprietary rights and know-how in the factors which assist us in utilizing the quantitative gene expression levels we measure and compute. Our proprietary rights related to conversion factors in quantitative gene expression levels do not include patent coverage. However, we have obtained patents claiming methods and products related to the determination of the expression levels of certain tumor response marker genes in the United States and in a number of other jurisdictions, including Austria, Australia, Belgium, Canada, France, Germany, Hong Kong, Ireland, Italy, Japan, Korea, Liechtenstein, The Netherlands, New Zealand, Spain, Sweden, Switzerland, Taiwan and the United Kingdom. The term of these patents will run until 2021 or 2022. These patents include five United States patents that relate to certain aspects of our proprietary technology useful in determining levels of the expression of the tumor marker genes including thymidylate synthase (TS), excision repair gene CC1 (ERCC1), dihydropyrimidine dehydrogenase (DPD), and glutathione-s transferase pi (GST-p).

Regulations and Legal Environment

Our business is subject to extensive laws and regulations, the most significant of which are summarized below.

Clinical Laboratory Improvement Amendments

We are subject to the Clinical Laboratory Improvement Amendments of 1988, or CLIA, which is administered by the Centers for Medicare and Medicaid Services or CMS which is part of the Secretary of the Department of Health & Human Services (“DHHS”) and extends federal oversight to virtually all clinical laboratories by requiring certification by the federal government or by a federally-approved accreditation agency. CLIA requires the certification of clinical laboratories that conduct tests on human subjects and imposes specific conditions for certification. CLIA is intended to ensure the quality and reliability of clinical laboratories, including the accuracy, reliability and timeliness of patient test results performed in clinical laboratories, in the United States by mandating specific standards in the areas of personnel qualification, administration participation in proficiency testing, patient test management, by implementing an effective Quality Management System. CLIA regulations contain guidelines for the qualification, responsibilities, training, working conditions and oversight of clinical laboratory employees. In addition, specific standards are imposed for each type of test that is performed in a laboratory. The categorization of commercially marketed in vitro diagnostic (“IVD”) test kits is the responsibility of the FDA. The FDA will assign commercially marketed test systems into one of three CLIA regulatory categories based on their potential risk to public health. Tests will be designated as waived, of moderate complexity or of high complexity. CLIA and the regulations promulgated thereunder are enforced through periodic inspections of the laboratory process including, but not limited to, inspections of test methods, equipment, instrumentation, materials and supplies. The sanction for failure to comply with CLIA requirements may be suspension, revocation or limitation of a laboratory's CLIA certificate, which is necessary to conduct business, as well as significant fines and/or criminal penalties. If a laboratory is certified as "high complexity" under CLIA, the laboratory is permitted to obtain analyte specific reagents (ASRs), which are commercially marketed products that function as the building blocks of in vitro diagnostic tests and in-house diagnostic tests known as "home brews” or Laboratory Developed Tests. We received our CLIA certificate as a "high complexity" laboratory in 2007. To renew this certificate, we participate in College of American Pathologist (“CAP”) surveys and unannounced periodic inspections approximately every two years. Our most recent CAP inspection took place on August 27, 2012 and has resulted in accreditation for two years starting November 4, 2012, the date of expiration of the previous accreditation. Loss of our CLIA certification, change in CLIA or CLIA regulations or in the interpretation thereof, could have a material adverse effect on our business.

Other Laboratory Regulations

Our clinical operations are also subject to regulation under state laws which in some areas are more stringent than CLIA. State clinical laboratory laws generally require that laboratories and/or laboratory personnel meet certain qualifications. State clinical laboratory laws also generally require laboratories to specify certain quality assurance metrics and to maintain certain records. For example, California requires that we maintain a state issued license and comply with California standards for our laboratory operations, including the standards for laboratory personnel and testing processes. Certain other states, including Rhode Island, Florida, Maryland, New York and Pennsylvania, require that we hold licenses to test specimens from patients residing in those states. Certain state regulations or standards differ from CLIA and CAP, requiring additional compliance work in order to maintain the applicable certification or license with that state. Additional states may require similar licenses in the future. Potential sanctions for violation of these state requirements include significant fines and the suspension or loss of various licenses, certificates and authorizations, which could adversely affect our business and results of operations. Finally, we may be subject to regulation in foreign jurisdictions, including in Europe and Asia, if we expand offering of our tests or distribution of our tests internationally.

HIPAA Compliance and Privacy Protection and the HITECH Act

The Health Insurance Portability and Accountability Act of 1996 (“HIPAA”) established comprehensive federal protection for the privacy and security of health information. The HIPAA standards apply to three types of organizations, or “Covered Entities:” health plans, health care clearing houses, and health care providers who conduct certain health care transactions electronically (“Standard Transactions”). Covered Entities must have in place administrative, physical and technical safeguards to protect against the misuse of individually identifiable health information, or PHI. Additionally, some state laws impose privacy protections more stringent than HIPAA’s and some states impose privacy obligations specifically applicable to clinical laboratories. Additionally, many states have implemented data breach laws requiring additional security measures for certain types of PHI and also public notification of the theft, breach or other loss of personal information. There are also international privacy laws, such as the European Data Directive and various national laws implementing the Data Directive, that impose restrictions on the access, use, and disclosure of health information and other types of identifiable personal information. All of these laws may impact our business. As of December 31, 2008, we became a Covered Entity subject to HIPAA privacy and security standards because our testing services became reimbursable by insurance payors and we began conducting Standard Transactions. We formed an active program designed to address HIPAA regulatory compliance. This program will likely require periodic updating to comply with amendments to HIPAA. Regardless of our own Covered Entity status, HIPAA presently applies to many of the facilities and physicians with whom we do business and controls the ways in which we may obtain tissue specimens and associated clinical information from those facilities and physicians. We believe we have taken the steps required for us to comply with applicable health information privacy and confidentiality statutes and regulations under both federal and applicable state jurisdictions. However, we may not be able to maintain compliance in all jurisdictions where we do business. Our failure to comply with these privacy laws or significant changes in the laws restricting our ability to obtain tissue specimens and associated patient information could significantly impact our business and our future business plans.

	11

Additionally, The Health Information Technology for Economic and Clinical Health Act of 2009 and the regulations promulgated thereunder by the Department of Health and Human Services (the “HITECH Act”) requires HIPAA covered entities, including clinical laboratories, to provide notification to affected individuals and to the Secretary of Health and Human Services, following discovery of a breach of unsecured PHI. In some cases, the HITECH Act requires covered entities to provide notification to the media of breaches. In the case of a breach of unsecured PHI at or by a business associate of a covered entity, the HITECH Act requires the business associate to notify the covered entity of the breach. The HITECH Act requires the Secretary of Health and Human Services to post on the Department of Health and Human Services’ website a list of covered entities that experience breaches of unsecured PHI involving more than 500 individuals. The HITECH Act made other changes relating to the HIPAA privacy and security rules, including, among others, establishing that, effective February 17, 2010, the security and privacy rules apply directly to business associates and, consequently, that a business associate’s violation of the rules may result in government enforcement action directly against the business associate.

Federal and State Physician Self-referral Prohibitions

We are subject to the federal physician self-referral prohibitions (the “Stark Law”) and restrictions under California’s Physician Ownership and Referral Act (“PORA”). These restrictions prohibit us from billing a patient or any governmental or private payor for any test when the physician ordering the test, or any member of such physician’s immediate family, has an investment interest in or compensation arrangement with us, unless the arrangement meets an exception to the prohibition.

Both the Stark Law and PORA contain an exception for referrals made by physicians who hold investment interests in a publicly traded company that has stockholders’ equity exceeding $75 million at the end of its most recent fiscal year or on average during the previous three fiscal years, and which satisfies certain other requirements. In addition, both the Stark Law and PORA contain an exception for compensation paid to a physician for personal services rendered by the physician. We have compensation arrangements with a number of physicians for personal services, such as speaking engagements and specimen tissue preparation. We have structured these arrangements with terms intended to comply with the requirements of the personal services exception to Stark Law and PORA.

However, we cannot be certain that regulators would find these arrangements to be in compliance with Stark Law, PORA or similar state laws. If we are deemed to not be in compliance by the applicable regulators, we would be required to refund any payments we receive pursuant to a referral prohibited by these laws to the patient, the payor or the Medicare program, as applicable.

Penalties for a violation of the Stark Law include: refunds of amounts collected by an entity in violation of the Start Law, denial of payment for the services provided in violation of the prohibition, and civil penalties of up to $15,000 per service arising out of the prohibited referral. Additionally, a person who engages in a scheme to circumvent the Stark Law’s prohibition may be subject to a civil penalty of up to $100,000. A violation of PORA is a misdemeanor and could result in civil penalties and criminal fines

Other states have self-referral restrictions with which we have to comply that differ from those imposed by federal and California law. While we have attempted to comply with these laws, it is possible that some of our financial arrangements with pathologist and physicians could be subject to regulatory scrutiny at some point in the future, and we cannot provide assurance that we will be found to be in compliance with these laws following any such regulatory review.

Federal False Claims Act

There are federal and state laws prohibiting fraudulent billing and providing for the recovery of non-fraudulent overpayments, as a large number of laboratories have been forced by the federal and state governments, as well as by private payors, to enter into substantial settlements under these laws. In particular, if an entity is determined to have violated the federal False Claims Act, it may be required to pay up to three times the actual damages sustained by the government, plus civil penalties ranging from $6,000 to $11,000 for each separate false claim. While there are many potential bases for liability under the federal False Claims Act, such liability primarily arises when an entity knowingly submits, or causes another to submit, a false claim for reimbursement to the federal government. Submitting a claim with reckless disregard or deliberate ignorance of its validity could result in substantial civil liability. A current trend within the healthcare industry is the increased use of the federal False Claims Act and, in particular, actions under the False Claims Act’s “whistleblower” or “qui tam” provisions to challenge providers and suppliers. Those provisions allow a private individual standing to bring actions on behalf of the government, alleging that the defendant has submitted a fraudulent claim for payment to the federal government. The government may join in the lawsuit, but if the government declines to do so, the individual may choose to pursue the lawsuit alone. The government must be kept apprised of the progress of the lawsuit. Whether or not the federal government intervenes in the case, it will receive the majority of any recovery. In addition, various states have enacted laws modeled after the federal False Claims Act.

Food and Drug Administration

The U.S. Food and Drug Administration, or the FDA, regulates the manufacturing and sale or distribution in interstate commerce, of medical devices, including IVD test kits. The information that must be submitted to the FDA in order to obtain clearance or approval to market a new medical device varies depending on how the medical device is classified by the FDA. Medical devices are classified into one of three classes on the basis of the controls deemed by the FDA to be necessary to reasonably ensure their safety and effectiveness. Class I devices are subject to general controls, including labeling, listing, registration, and reporting. It may also include pre-market notification and adherence to the FDA’s quality system regulation, which are device-specific good manufacturing practices. Class II devices are subject to general controls and special controls, such as performance standards and post-market surveillance. Class III devices are subject to most of the previously identified requirements as well as to pre-market approval. Most IVD kits are regulated as Class I or Class II devices. Entities that fail to comply with FDA requirements can be liable for criminal or civil penalties, recalls, seizures, orders to cease manufacturing and restrictions on labeling and promotion.

The FDA presently requires clearance or approval of diagnostic test kits that are sold to labs, hospitals and doctors, considering them to be medical devices. However, diagnostic tests that are developed and performed by a CLIA-certified reference laboratory, known as “home-brew,” “in-house” or “laboratory-developed” tests, have not been regulated by FDA to date. The FDA has stated that it has the power to regulate laboratory-developed tests such as the ones that we develop. Nevertheless, it has exercised enforcement discretion and not regulated most laboratory-developed tests performed by high complexity CLIA certified laboratories.

The FDA has stated that it intends to regulate some laboratory-developed tests as devices. The FDA has said it will develop guidelines describing which tests would need to comply with device requirements. The degree to which in-house tests are regulated by the FDA has also been the focus of recent Congressional attention, and Congress is considering the introduction of legislation that would subject at least some such tests to premarket review or approval by the FDA.

The cancer therapy response tests being developed by the Company include the use of genes and determine whether a patient falls into a high or low risk for recurrence of response to a particular therapy. The Company plans to continue to develop and offer these tests as ”laboratory-developed” tests unless it becomes clearer that these tests are subject to regulation by the FDA. We will continue to monitor both the FDA and Congress and we intend to comply with any new requirements that may apply.

Good Laboratory Practice (“GLP”) and Good Clinical Laboratory Practices (“CGLP”)

We are subject to various regulatory requirements designed to ensure the quality and integrity of our non-clinical and pre-clinical testing processes. Our standard operating procedures are written in accordance with applicable regulations and guidelines or Code of Federal Regulations for operating in the United States. The industry standards for conducting preclinical laboratory testing are embodied in GCLP regulations promulgated by the FDA. In the United States, non-clinical studies intended for FDA submission must be conducted in accordance with GLP regulations; foreign governments may require our North American clients to comply with certain regulatory requirements of other countries (in order to gain approval within these countries), such as regulations promulgated by the Japanese Ministry of Health, Labor and Welfare and Ministry of Agriculture, Forestry and Fisheries, and in Europe, the Organization for Economic Co-operation and Development. GLP regulations specify requirements for facilities, equipment, and professional staff and standardized procedures for conducting studies, including procedures for recording and reporting data and for managing study materials and records. We have established a required quality assurance system that monitors ongoing compliance with GLP regulations by auditing test data and reporting and conducting inspections of testing procedures.

Our business is also subject to regulation under state and federal laws regarding environmental protection and hazardous substances control, such as the Federal Occupational Safety and Health Act, the Environmental Protection Act, and Toxic Substances Control Act. These regulations, among other things, require work practice controls, protective clothing and equipment, training and other measures designed to minimize exposure to chemicals and transmission of pathogens. We believe that we are in compliance with these and other applicable laws and that the costs of our ongoing compliance will not have a material adverse effect on our business. However, statutes and regulations applicable to our business may be adopted which impose substantial costs to assure compliance or otherwise materially adversely affect our operations.

Regulation of Reimbursement and Coverage

Revenues for clinical laboratory testing services come from a variety of sources and depend significantly on the availability of third-party reimbursement, including from Medicare and Medicaid programs, commercial insurers and managed care organizations. We are currently a Medicare laboratory services provider and intend to become a Medicaid laboratory services provider. We also receive reimbursement from third-party payors for our testing services. As is the case with health care services generally, the majority of payors pay for our testing services at varying levels that may be significantly lower or otherwise differ from our list prices. Obtaining reimbursement from third-party payors is both time consuming and expensive. Payment from third-party payors may not be sufficient to allow us to sell our services on a profitable and competitive basis.

	13

We derived approximately 45% and 38% of our net sales of ResponseDX ^® testing services directly from the Medicare program in 2012 and 2013, respectively. Therefore, compliance with complex Medicare reimbursement rules is important to our operations. Once Medicare has determined that it will cover a particular test, or that a test will be provided as a benefit, payment is generally made under the Clinical Laboratory Fee Schedule with amounts assigned to specific procedure billing codes. Each Medicare carrier jurisdiction has a fee schedule that establishes the price for each specific laboratory billing code. This fee schedule is updated annually. As a Medicare-participating laboratory based in California, we bill under the Medicare program's California contractors fee schedule and will have to comply with this contractor's coverage and payment policies. In recent years, both government and private sector payers have made efforts to contain or reduce health care costs, including reimbursement for clinical laboratory services. In January 2013, the initial 2013 annual Medicare fee schedule update was announced which included proposed changes to Medicare reimbursement rates that significantly reduced the reimbursement rates for certain of the testing services we provide. The Company participated with other impacted organizations to provide guidance to the local Medicare Administrative Contractor (“MAC”) that may result in adjustments to the proposed reimbursement rates to better reflect the value of the services being performed. As a result of this guidance, the local MAC updated certain pricing through September 2013 which reflected an increase in many of the tests originally priced in January 2013. On October 1, 2013, the CMS issued fees for some, but not all, of the Common Procedural Terminology (“CPT”) codes used by the Company. It is uncertain if continued guidance provided to Medicare and the local MAC by impacted organizations will result in additional fee increases or additional positive coverage determinations in 2014. If, however, the current level of reduction in reimbursement rates is adopted as is, it may have a material adverse effect on the Company's operations.

Manufacturing

We currently intend to rely on contracted manufacturers or collaborative partners to produce materials necessary for our research and development efforts and to produce our diagnostic tests. We plan to continue to rely on these manufacturers and collaboration partners to manufacture these materials if any of our diagnostic tests is approved for marketing by the FDA or any foreign regulatory authority. We do not have manufacturing experience. We may not be able to identify or enter into satisfactory agreements with collaborative partners.

Information Technology

We have implemented a commercially available and supported system used to perform tracking, evaluation, and reporting of laboratory specimens as they are analyzed. Hardware and software used in conjunction with this system are commercially available items that can easily be procured. We also make use of commercial software applications that allow for biostatistical analysis of data generated.

Industry standard tools and techniques are used to support business functions on the Company informatics environment. This includes areas such as office applications, collaboration, electronic mail, general ledger/accounting software, internet connectivity, backup strategies, and security measures.

Specimen storage equipment consists of lockable cabinets that are catalogued for the storage of paraffin-embedded specimens for our clients. Our database provides locator information in order to retrieve these archived specimens as needed. In addition, we maintain freezers to store frozen tissue specimens. These freezers are monitored via computerized probes on a continuous basis to ensure that temperatures are maintained at levels necessary to keep these specimens frozen. Should temperatures in any of the freezers move out of range due to mechanical failure an emergency alert is sent to us for response. These freezers are also supported by a freestanding emergency backup generator that will engage in the event of a general power outage in order to maintain freezer temperatures at necessary levels.

Competition

We provide services in a segment of the healthcare industry that is highly fragmented and extremely competitive. Any failure to respond to technological advances and emerging industry standards could impair our ability to attract and retain clients. This industry is characterized by rapid technological change. The Company’s actual and potential competitors in the United States and abroad may include major clinical and pathology laboratories, such as Quest Diagnostics Inc., Laboratory Corporation of America, Clarient, Inc. (acquired by GE), and specialized laboratories such as Genoptixs Inc. (acquired by Novartis Pharmaceuticals), NeoGenomics, Inc., Caris Life Sciences, Foundation Medicine, university laboratories and other research institutions. Many of our potential competitors have considerably greater financial, technical, marketing, research and other resources than we do, which may allow these competitors to discover important information and technology before we do. We anticipate competition to aggressively compete for market share. Our competitors may succeed in developing diagnostic products that circumvent our technologies or product candidates. Also, our competitors may succeed in developing technologies or products that are more effective than those that are developed or will be developed by us or that would render our technology or product candidates less competitive or obsolete.

In addition, we are developing our services and product candidates to impact certain methods for treating cancer. If those methods change, it is likely that the demand for our services and product candidates could significantly decline or cease altogether. The development of new or superior competing technologies or products, or a change in the methodology of treating cancer, could affect our competitive position and harm our business. Moreover, these competitors may offer broader product lines and have greater name recognition than us and may offer discounts as a competitive tactic.

Additionally, several development-stage companies are currently making or developing product candidates that compete with or will compete with our potential products. Competitors may succeed in developing, obtaining approval from the FDA or marketing technologies or products that are more effective or commercially attractive than our potential products or that render our technologies and current or potential products obsolete. Competitors may also develop proprietary positions that may prevent us from commercializing product candidates.

Recent Sales of Unregistered Securities

February 2012 Private Placement

On February 2, 2012, the Company entered into purchase agreements with various investors (collectively, the “February Investors”) for the private placement of an aggregate of 5,257,267 newly-issued shares of the Company’s common stock (the “February Shares”) at a purchase price of $1.50 per share (the “February 2012 Private Placement”). Net cash proceeds raised in the February 2012 Private Placement were approximately $7,822,000. The February Investors participating in the February 2012 Private Placement were various institutions and all the then serving officers and directors of the Company. The final closing of the February 2012 Private Placement (the “February Closing”) occurred on February 2, 2012.

In connection with the February 2012 Private Placement, the Company also entered into registration rights agreements, each dated February 2, 2012, with the February Investors pursuant to which the Company agreed to file, within 90 days of the February Closing, a registration statement with the SEC to register the February Shares for resale, which registration statement was required to become effective within 180 days following the February Closing. The Company also granted the February Investors certain “piggyback” registration rights, which are triggered if the Company proposes to file a registration statement for its own account or the account of one or more shareholders until the earlier of the sale of all of the February Shares or the February Shares becoming eligible for sale under Rule 144(b)(1) without restriction.

Pursuant to the registration rights agreements dated February 2, 2012, the Company filed a registration statement with the SEC on April 30, 2012, to register the February Shares for resale. This registration statement became effective on May 17, 2012 and remained effective as of December 31, 2013.

Under the registration rights agreements with the February Investors, the Company is obligated to use commercially reasonable efforts to (i) cause the registration statement described above to remain continuously effective and (ii) to maintain the listing of the Company’s common stock on NASDAQ or other exchanges, as defined, for a period that will terminate on the earlier of February 2, 2013, the date on which the February Investors have sold all covered registrable securities or the date on which there are no longer any covered registrable securities outstanding. The Company is also required to file with the SEC in a timely manner all reports and other documents required of the Company required of the Company under the Exchange Act. In the event the Company fails to satisfy its obligations under the registration rights agreements, the Company would be in breach of said agreements, in which event, the February Investors would be entitled to pursue all rights and remedies at law or equity including an injunction or other equitable relief. These registration rights agreements do not provide an explicitly stated or defined penalty due upon a breach. Because (i) the potential penalty for any breach of these registration rights agreement is not explicitly stated or defined, which prohibits the Company from applying the guidance of ASC 825-20-15, Registration Payment Arrangements and (ii) complying with all filing requirements under the Exchange Act as described above is not solely within the Company’s control, the Company was required to present the investment of approximately $7,885,900 in the Company’s common stock as common stock outside of stockholders’ equity in the accompanying consolidated balance sheet under ASC 480-10-S99-3, Classification and Measurement of Redeemable Securities.

As of December 31, 2012, the Company had removed the restrictions on 3,100,000 shares and reclassified the shares to common stock from common stock classified outside of equity (deficit). Therefore, as of December 31, 2012, a total of $3,183,328 of February 2012 Private Placement common stock was classified outside of stockholders’ equity (deficit). During 2013, the restrictions on the remaining February Shares were removed, and the Company reclassified the related amount for the February Shares to common stock from common stock classified outside of equity (deficit).

September 2012 Private Placement

On September 13, 2012, the Company entered into a purchase agreement (the “Purchase Agreement”) with Glaxo Group Limited, an affiliate of GSK (the “GSK Investor”) and two existing investors, Swiftcurrent Partners, L.P. and Swiftcurrent Offshore, Ltd. (collectively with the GSK Investor, the “September Investors”) for the private placement of an aggregate of 8,000,000 newly-issued shares of the Company’s common stock (the “September Shares”) at a purchase price of $1.10 per share (the “September 2012 Private Placement”). The Company raised gross cash proceeds of $8,800,000 in the September 2012 Private Placement, which closed on September 13, 2012 (the “Closing”).

Pursuant to the Purchase Agreement, for so long as the GSK Investor or its affiliates own at least 50% of the September Shares it purchased pursuant to the Purchase Agreement, the GSK Investor has the right to designate one non-voting board observer (the "Board Observer"). The Board Observer, if appointed, has the right to attend all meetings of the Board of Directors of the Company and to receive all board meeting materials, subject to certain restrictions set forth in the Purchase Agreement. As of the date hereof, the GSK Investor has not exercised its right to designate the Board Observer.

In connection with the September 2012 Private Placement, the Company also entered into a registration rights agreement, dated September 13, 2012 (the “September Registration Rights Agreement”), with the September Investors pursuant to which the Company agreed to file, within 45 days of the Closing, a registration statement with the SEC to register the September Shares for resale, which registration statement was required to become effective within 180 days following the Closing. The Company also granted the September Investors certain “piggyback” registration rights, which are triggered if the Company proposes to file a registration statement for its own account or the account of one or more stockholders until the earlier of the sale of all of the September Shares or the September Shares becoming eligible for sale under Rule 144(b)(1) without restriction.

	17

Under the September Registration Rights Agreement, the Company is obligated to use commercially reasonable efforts to cause a registration statement to become effective and to remain continuously effective and to maintain the listing of the covered common stock on NASDAQ or other exchanges, as defined, for a period that will terminate upon the earlier of (i) the date on which all Registrable Securities covered by such Registration Statement as amended from time to time, have been sold, (ii) the date on which there are no longer any Registrable Securities outstanding or (iii) three years from the date of filing of such Registration Statement (the “Effectiveness Period”) and advise each September Investor in writing when the Effectiveness Period has expired. “Registrable Securities” means (i) the September Shares and (ii) shares of capital stock or any other securities issued or issuable with respect to or in exchange for the September Shares; provided, that, a security shall cease to be a Registrable Security with respect to a September Investor upon (A) sale by such September Investor pursuant to a registration statement or Rule 144 under the Securities Act of 1933, or (B) such security becoming eligible for sale by such September Investor without restriction pursuant to Rule 144(b)(1). In the event the Company fails to satisfy its obligations under the September Registration Rights Agreement, the Company would be in breach of such agreement, in which event, the September Investors would be entitled to pursue all rights and remedies at law or equity including an injunction or other equitable relief. The September Registration Rights Agreement does not provide an explicitly stated or defined penalty due upon a breach. Because the potential penalty for any breach of these registration rights agreement is not explicitly stated or defined, which prohibits the Company from applying the guidance of ASC 825-20-15, Registration Payment Arrangements , the Company was required to present the investment of approximately $8,800,000 in the Company’s common stock as common stock outside of stockholders’ equity in the accompanying consolidated balance sheet under ASC 480-10-S99-3, Classification and Measurement of Redeemable Securities .

Pursuant to the September Registration Rights Agreement, the Company filed a registration statement with the SEC on October 26, 2012, to register the September Shares for resale. This registration statement became effective on November 13, 2012 and remained effective as of December 31, 2013.

As of December 31, 2012, the Company had removed the restriction on 3,000,000 of the 8,000,000 September Shares and reclassified the shares to common stock from common stock classified outside of stockholders’ equity (deficit). Therefore, as of December 31, 2012 and 2013, a total of $5,500,000 of common stock relating to the 5,000,000 remaining restricted September Shares was classified outside of stockholders’ equity (deficit).

Item 6. Selected Financial Data

The information called for by this item is not required as we are a smaller reporting company.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations .

Special Note Regarding Forward-Looking Statements

The following discussion of our financial condition and results of operation should be read in conjunction with our audited consolidated financial statements and related notes to the consolidated financial statements included elsewhere in this Annual Report on Form 10-K for the year ended December 31, 2013. This discussion contains forward-looking statements that relate to future events or our future financial performance. These statements involve known and unknown risks, uncertainties and other factors that may cause our actual results, levels of activity, performance or achievements to be materially different from any future results, levels of activity, performance or achievements expressed or implied by these forward-looking statements.

Overview

Response Genetics, Inc. (the “Company”) was incorporated in the State of Delaware on September 23, 1999 as Bio Type, Inc. for the purpose of providing unique molecular profiling services of tumor tissue that has been formalin-fixed and embedded in paraffin. In August 2000, we changed our name to Response Genetics, Inc.

Our Approach

Continued commercialization of our ResponseDX ^® tests;

Broadening our offerings with the introduction of the former Pathwork Diagnostics Tissue of Origin test that was acquired when we purchased the Pathwork Diagnostics assets in August of 2013;

Developing additional diagnostic tests for predicting therapy response and determining the diagnosis and prognosis of solid tumors in cancer patients;

Expanding our testing services business by pursuing new technologies through collaborations and in-licensing to expand our business; and

Selectively building our pharmaceutical services business.

Our technologies enable us to reliably and consistently extract the nucleic acids, ribonucleic acid (“RNA”) and deoxyribonucleic acid (“DNA”), from tumor specimens that are stored as formalin-fixed and paraffin-embedded (“FFPE”), specimens and thereby to analyze genetic information contained in these tissues. This is significant because the majority of patients diagnosed with cancer have a tumor biopsy sample stored in paraffin, while only a small percentage of patients’ tumor specimens are frozen. Our technologies also enable us to use the FFPE patient biopsies for the development of new diagnostic tests.

ResponseDX ^®

Until recently, most cancer treatment regimens were administered without any pre-selection of patients on the basis of the particular genetics of their tumor. However, advances in molecular technologies have enabled researchers to identify and measure genetic factors in patients’ tumors that may predict the probability of success or failure of many anti-cancer agents. In order to increase the chances of a better outcome for cancer patients, we offer and continue to expand our offering of tests for measuring predictive factors for therapy response in tumor tissue samples. We provide tests for non-small cell lung cancer (“NSCLC”), colorectal cancer (“CRC”), gastric and gastroesophageal cancer (“GE”), melanoma, thyroid cancer, and breast cancer patients’ tumor tissue specimens through our ResponseDX: Lung ^® , ResponseDX: Colon ^® , ResponseDX: Gastric ^® , ResponseDX: Melanoma ^® , ResponseDX: Thyroid ^TM and ResponseDX: Breast ^TM test suites at our laboratory located in Los Angeles, California, which is certified under the Clinical Laboratory Improvement Amendments of 1988 (“CLIA”). These tests serve to help oncologists make optimal therapeutic decisions for cancer patients. The results from our tests may help oncologists choose among therapies to treat their cancer patients.

As of December 31, 2013, our ResponseDX ^® sales team consisted of 21 members located in the West, Southeast, and Northeast areas of the United States.

Expansion of our ResponseDX ^® diagnostic test panels

Addition of Next-Generation Sequencing to our suite of technologies

Pursue Additional Collaborations and In-licensing to Expand Our Business

Research and development is crucial to the Company’s development as we seek to expand our series of diagnostic tests for cancer patients. Our research and development expenses were $2,128,610 and $1,606,662 for the years ended December 31, 2012 and 2013, respectively, representing 11.4% and 8.1% of our net revenue for the years ended December 31, 2012 and 2013, respectively. Major components of our research and development expenses include supplies and reagents for our research activities, personnel costs, occupancy costs, equipment warranties and service, patent fees, insurance, business consulting and sample procurement costs. We expect research and development expenses to increase as we work to develop additional aspects of our technology and to study diagnostic indicators for various forms of cancer.

Critical Accounting Policies and Significant Judgments and Estimates

This discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). The preparation of these financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities and expenses and the disclosure of contingent assets and liabilities at the date of the financial statements, as well as revenues and expenses during the reporting periods. We evaluate our estimates and judgments on an ongoing basis. We base our estimates on historical experience and on various other factors we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results could therefore differ materially from those estimates under different assumptions or conditions. We believe the following critical accounting policies reflect our more significant estimates and assumptions used in the preparation of our financial statements.

	19

Revenue Recognition

Pharmaceutical Revenue

Revenues that are derived from pharmacogenomic testing services provided to pharmaceutical companies are recognized on a contract specific basis pursuant to the terms of the related agreements. Revenue is recognized in accordance with ASC 605, Revenue Recognition, which requires that four basic criteria must be met before revenue can be recognized: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred and title and the risks and rewards of ownership have been transferred to the client or services have been rendered; (3) the price is fixed or determinable; and (4) collectability is reasonably assured.

Revenues are recorded on an accrual basis as the contractual obligations are completed and as a set of assays is processed through the Company’s laboratory under a specified contractual protocol and are recorded on the date the tests are completed. Certain contracts have minimum assay requirements that, if not met, result in payments that are due upon the completion of the designated period. In these cases, revenues are recognized when the end of the specified contract period is reached.

In March 2010, the Company entered into a non-exclusive license agreement with GlaxoSmithKline, LLC, which called for certain milestone payments to be made to the Company when certain events specified in the agreement occur, specifically GlaxoSmithKline, LLC submitting an application to use the license to the FDA, the FDA approving the application, and issuance of certain patent applications to the Company. The Company has no further obligations related to these events and therefore has recorded the milestone payments that were due under the agreement into revenue at the time the event occurred. The Company incurred no additional cost related to these revenues at the time these events occurred.

ResponseDX ^® Revenue

Net revenue for the Company’s diagnostic services is recognized on an accrual basis at the time discreet diagnostic tests are completed. Each test performed relates to a specimen encounter derived from a patient, and received by the Company on a specific date (such encounter is commonly referred to as an “accession”). The Company’s services are billed to various payors, including Medicare, private health insurance companies, healthcare institutions, and patients. The Company reports net revenue from contracted payors, including certain private health insurance companies, and healthcare institutions based on the contracted rate, or in certain instances, the Company’s estimate of the amount expected to be collected for the services provided. For billing to Medicare, the Company uses the published fee schedules, net of standard discounts (commonly referred to as “contractual allowances”). The Company reports net revenue from non-contracted payors, including certain private health insurance companies, based on the amount expected to be collected for the services provided. The Company analyzes historical payments from payors as a percentage of amounts billed by the Company to estimate expected collections for purposes of recording net revenue.

The Company has its Medicare provider number which allows it to invoice and collect from Medicare. Invoicing to Medicare is primarily based on amounts allowed by Medicare for the service provided as defined by Common Procedural Terminology (“CPT”) codes. In January 2013, the initial 2013 annual Medicare fee schedule update was announced which included proposed changes to Medicare reimbursement rates that significantly reduced the reimbursement rates for certain of the testing services we provide. The Company participated with other impacted organizations to provide guidance to the local Medicare Administrative Contractor (“MAC”) that resulted in the local MAC updating certain pricing through September 2013 which reflected an increase in many of the tests originally priced in January 2013. In addition, on October 1, 2013, the Centers for Medicare and Medicaid Services (“CMS”) issued fees for some, but not all, of the CPT codes used by the Company. It is uncertain if continued guidance provided to Medicare and the local MAC by impacted organizations will result in additional fee increases or additional positive coverage determinations in 2014. If, however, the current level of reduction in reimbursement rates is adopted as is, it may have a material adverse effect on the Company's operations.

	20

As a result of these CPT code changes and Medicare price changes, we have experienced a departure from our normal reimbursement patterns with Medicare and other payors. Specifically, we have experienced delays in certain reimbursements for services and an increase in initial denials of claims for certain services provided. Accordingly, we re-evaluated the assumptions employed in our model for estimating revenue to be recognized for ResponseDX ^® testing. We view the code and price changes described above as affecting only the assumptions we used in pricing our services. The nature of the testing we provide, the evidence we gather to establish the creditworthiness of our payors and the delivery method of our services have not changed from prior periods, and there are no indicators that these assumptions require change.

We performed an analysis that considered our historical patterns of revenue by payor in conjunction with the fluctuations we experienced in the twelve months ended December 31, 2013 to arrive at the revenue recorded during 2013. We believe that the changes in CPT codes and pricing that are causing confusion and erratic payment experience in the payor community will take some time to resolve. The time needed for resolution will depend upon Medicare and the local MAC releasing additional pricing changes and potentially, revisions to previously revised prices, and upon the private payor community adopting the new CPT codes and some level of revised pricing. Accordingly, our revenue recognition estimates could be materially affected in future periods as pricing and payment patterns change and develop, and we may be materially affected by future or retroactive price changes.

On July 8, 2013, CMS released a new proposed rulemaking entitled “Medicare Program; Revisions to Payment Policies under the Physician Fee Schedule, Clinical Laboratory Fee Schedule & Other Revisions to Part B for CY 2014”. This proposed rule contains a number of provisions that may adversely impact the level of reimbursement for a variety of tests for which the Company receives reimbursement from the Medicare program beginning in 2014. Among other things, CMS has proposed examining approximately 1,200 laboratory tests that appear on the Clinical Lab Fee Schedule (“CLFS”) over a period of five years to determine whether advances in technology may have reduced the cost of providing such tests and whether or not the level of reimbursement should be revised. The Company is currently performing molecular testing which is reimbursed using CPT codes that fall on the CLFS. CMS has also proposed changing the methodology used to determine reimbursement rates for the technical component of certain tests reimbursed off of the Physician Fee Schedule (“PFS”). Among other provisions, CMS has proposed limiting the Relative Value Units (“RVUs”) ascribed to the Practice Expense component of their reimbursement formula for tests performed in “Non-Facilities” (which would include most clinical laboratories like the Company) to the RVUs that have been ascribed for the same procedures under the Hospital Outpatient Prospective Payment System, or the Ambulatory Payment Classification (“APC”) system which are used to reimburse “Facilities” (such as hospitals and ambulatory surgery centers). The Company currently performs FISH testing, which may be impacted by this PFS rule change if it is enacted.

A number of proposals for legislation or regulation continue to be under discussion which could have the effect of substantially reducing Medicare reimbursements for clinical laboratories or introducing cost sharing to beneficiaries. Depending upon the nature of regulatory action, if any, which is taken and the content of legislation, if any, which is adopted, the Company could experience a significant decrease in revenues from Medicare and Medicaid, which could have a material adverse effect on the Company. The Company is unable to predict, however, the extent to which such actions will be taken.

License Fees

We have licensed technology for the extraction of RNA and DNA from FFPE tumor specimens from USC in exchange for royalty fees on revenue generated by use of this technology. These royalties are calculated as a fixed percentage of revenue that we generate from use of the technology licensed from USC. Total license fees expensed in cost of revenue under the license agreement with USC were $332,504 and $305,616 for the years ended December 31, 2012 and 2013, respectively. We also maintain a non-exclusive license to use Roche’s PCR, homogenous PCR, and reverse transcription PCR processes. We pay Roche a fixed percentage royalty fee for revenue that we generate through use of this technology. Royalties expensed in cost of revenue under the Roche agreement totaled $336,285 and $280,325 for the years ended December 31, 2012 and 2013, respectively.

We are subject to potentially significant variations in royalties recorded in any period. While the amount paid is based on a fixed percentage from revenues of specific tests pursuant to terms set forth in the agreements with USC and Roche, the amount due is calculated based on the revenue we recognize using the respective licensed technology. As discussed above, this revenue can vary from period to period as it is dependent on the timing of the specimens submitted by our clients for testing and the types of tests ordered.

Accounts Receivable and Allowance for Doubtful Accounts

We invoice our pharmaceutical clients as specimens are processed and any other contractual obligations are met. Our contracts with pharmaceutical clients typically require payment within 45 days of the date of invoice. We maintain allowances for doubtful accounts for estimated losses resulting from the inability of our clients to make required payments. We specifically analyze accounts receivable and historical bad debts, client credit, current economic trends and changes in client payment trends when evaluating the adequacy of the allowance for doubtful accounts. Account balances are charged-off against the allowance when it is probable the receivable will not be recovered. To date, our clients have primarily been large pharmaceutical companies. Bad debts to date have been minimal and there is no allowance for doubtful accounts for our pharmaceutical revenue at December 31, 2012 and 2013.

	21

We bill Medicare and private payors (“Private Payors”) for ResponseDX ^® upon completion of the required testing services. As such, we take assignment of benefits and the risk of collection with Medicare and Private Payors. We continue to monitor the collection history for Medicare and Private Payors. Based on the historical experience for our Medicare and Private Payor accounts, we have determined, based on a detailed analysis, that accounts receivable associated with certain billings are unlikely to be collected. As part of its process for evaluating the collectability of aged accounts receivable, Management identified delays in the Medicare administrative law appeal process for aged accounts receivable that would extend the process significantly (up to two years). Accordingly, management considered this factor in estimating the allowance for doubtful accounts and concluded that an additional allowance of approximately $690,000 was necessary as of December 31, 2013 to reserve for the balance of Medicare accounts receivable as of December 31, 2013 that were going to age greater than one year during the first quarter of 2014. Therefore, we have recorded an allowance for doubtful accounts of $991,990 and $2,404,659 as of December 31, 2012 and 2013, respectively.

An allowance for doubtful accounts is recorded for estimated uncollectible amounts due from the Company’s various payor groups. The process for estimating the allowance for doubtful accounts involves significant assumptions and judgments. Specifically, the allowance for doubtful accounts is adjusted periodically, and is principally based upon an evaluation of historical collection experience of accounts receivable for the Company’s various payor classes. After appropriate collection efforts, accounts receivable are written off and deducted from the allowance for doubtful accounts. Additions to the allowance for doubtful accounts are charged to bad debt expense. The payment realization cycle for certain governmental and managed care payors can be lengthy, involving denial, appeal, and adjudication processes, and is subject to periodic adjustments that may be significant.

We cannot guarantee that we will continue to experience the same credit loss rates that we have in the past. Measurement of such losses requires consideration of historical loss experience, including the need to adjust for current conditions, and judgments about the probable effects of relevant observable data, including present economic conditions such as delinquency rates and financial health of specific customers. We consider all available information in our assessments of the adequacy of the reserves for uncollectible accounts.

Income Taxes

We estimate our tax liability through calculations we perform for the determination of our current tax liability, together with assessing temporary differences resulting from the different treatment of items for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are recorded in our balance sheets. Our management then assesses the likelihood that deferred tax assets will be recovered in future periods through future operating results. To the extent that we cannot conclude that it is more likely than not that the benefit of such assets will be realized, we establish a valuation allowance to adjust the net carrying value of such assets. The carrying value of our net deferred tax assets assumes that we will be able to generate sufficient future taxable income, based on management’s estimates and assumptions. These estimates and assumptions take into consideration future taxable income and ongoing feasible tax strategies in determining recoverability of such assets. Our valuation allowance is subject to significant change based on management’s estimates of future profitability and the ultimate realization of the deferred tax assets. The Company has established a full valuation allowance against its net deferred tax assets due to the uncertainty surrounding the realization of such assets.

Results of Operations

Years Ended December 31, 2013 and December 31, 2012

Revenue . Revenue was $19,801,359 for the year ended December 31, 2013, as compared to $18,736,669 for the year ended December 31, 2012, an increase of $1,064,690 or 5.7%. The increase was primarily due to an increase in pharmaceutical revenue of $937,449. ResponseDX ^® revenue increased $127,241, an increase of 1.1%. ResponseDX ^® revenue accounted for 60.7% of total revenue in the year ended December 31, 2013 compared to 63.4% for the year ended December 31, 2012. ResponseDX ^® revenue increased slightly over the prior year as a result of increased staffing of our sales force offset by the lead time required to secure new customers as the Company’s sales and marketing efforts shifted toward larger customers. For the year ended December 31, 2013, our two most significant pharmaceutical clients accounted for approximately 23.8% of our revenue, as compared to approximately 24.1% of our revenue for the year ended December 31, 2012.

Cost of Revenue . Cost of revenues for the year ended December 31, 2013 was $10,456,082 as compared to $10,415,913 for the year ended December 31, 2012, an increase of $40,169, or 0.4%. While total cost of revenue was consistent with the prior year, costs increased for laboratory reagents and supplies by $315,845, personnel expense by $268,071 and depreciation and amortization by $162,941. These increases were offset by reductions in costs related to our agreement with Hitachi that ended in September 2012 by $526,823 and lower consulting expenses by $166,182. Cost of revenues as a percentage of revenues was 52.8% for the year ended December 31, 2013, as compared to 55.6% for the year ended December 31, 2012.

Research and Development Expenses . Research and development expenses were $1,606,662 for the year ended December 31, 2013, as compared to $2,128,610 for the year ended December 31, 2012, a decrease of $521,948 or 24.5%. The decrease primarily resulted from lower laboratory supplies, reagents and microarray costs of $302,256 and legal services related to our intellectual property of $137,453. We expect research and development expenses to increase as we work to develop additional aspects of our technology, launch Next Generation Sequencing and study diagnostic indicators for various forms of cancer.

	22

General and Administrative Expenses . General and administrative expenses totaled $10,262,623 for the year ended December 31, 2013, as compared to $8,783,414 for the year ended December 31, 2012, an increase of $1,479,209 or 16.8%. This increase resulted primarily from increases in bad debt expense of $1,814,325 to increase the allowance for bad doubtful accounts while the uncertainties in the payor environment around molecular pathology reimbursement are still being resolved and as the time required to appeal reimbursement decisions and policies with CMS has increased substantially from prior years. Additionally, personnel expenses increased by $215,861 related to higher staffing. The total increase in general and administrative expenses was offset by decreases in legal and accounting fees of $244,444, repair and maintenance of $143,100, telecommunication expenses of $88,753, and insurance expense of $75,500.

Sales and Marketing Expenses . For the year ended December 31, 2013, our sales and marketing expenses totaled $5,421,797 compared to $5,065,998 for the year ended December 31, 2012, an increase of $355,799 or 7.0%. The increase primarily resulted from restructuring and expanding our sales force and marketing activities during 2013, which resulted in higher personnel costs of $474,788 and increases in travel expenses of $154,132. These increases were offset by decreases in trade show expenses of $130,279, printing expense of $92,727 and speaker fees of $51,757. We expect that sales and marketing costs will increase as we continue to expand our sales and marketing team and related activities.

Other Income and Expense . Other income and expense primarily represents the interest expense we incur on our revolving credit facility with Silicon Valley Bank and capital leases as well as our realized and unrealized foreign currency exchange gains or losses on our Euro-denominated receivables. Interest expense increased to $91,844 for the year ended December 31, 2013 compared with $85,838 for the year ended December 31, 2012. Realized and unrealized losses on currency exchange rate fluctuations were a net gain of $17,086 for the year ended December 31, 2013 compared to net loss of $14,002 for the year ended December 31, 2012.

Net Loss . As a result of the foregoing, our net loss increased by $263,436 to $8,020,515 for the year ended December 31, 2013 as compared to a net loss of $7,757,079 for the year ended December 31, 2012.

Liquidity and Capital Resources

We incurred net losses of $7,757,079 and $8,020,515 during the years ended December 31, 2012 and 2013, respectively. Since our inception in September 1999, we have incurred cumulative losses and as of December 31, 2013, we had an accumulated deficit of $65,297,179. We have not yet achieved profitability and anticipate that we will likely incur additional losses for the next year. We cannot provide assurance as to when we will achieve profitability. We expect that our cash and cash equivalents will be used to fund our selling and marketing activities primarily related to our ResponseDX ^® tests, research and development, and general corporate purposes. As a result, we will need to generate significant revenues to achieve profitability.

The Company’s current operating plan includes various assumptions concerning the level and timing of cash receipts from sales and cash outlays for operating expenses and capital expenditures. The Company’s ability to successfully carry out its business plan is primarily dependent upon its ability to (1) obtain sufficient additional capital at acceptable costs, (2) attract and retain knowledgeable workers, and (3) generate significant revenues. At this time, the Company expects to satisfy its future cash needs primarily through additional financing and/or strategic investments. The Company is currently seeking such additional financing and/or strategic investments; however, there can be no assurance that any additional financing or strategic investments will be available on acceptable terms, if at all. If the Company is unable to timely and successfully raise additional capital and/or achieve profitability, it will not have sufficient capital resources to implement its business plan or continue its operations, and the Company will most likely be required to reduce certain discretionary spending, which could have a material adverse effect on the Company’s ability to achieve its intended business objectives. No adjustments have been made to the accompanying financial statements to reflect any of the matters discussed above.

On July 14, 2011, the Company entered into a line of credit agreement with Silicon Valley Bank (the “Bank”). The agreement has been amended most recently on March 7, 2013. The line of credit is collateralized by the Company’s pharmaceutical, Private Payor and Medicare receivables. The amended maximum amount that can be borrowed from the credit line is $2,000,000. As of December 31, 2013, the amount the Company can draw from the loan was $1,000,000 calculated as the lesser of (i) the Company’s calculated borrowing base, which was 80% of certain of the Company’s accounts receivable, or (ii) the amount available under the credit line. As of December 31, 2013, the interest fees associated with this line of credit were set at the prime rate plus 1%. During 2012 and 2013, the rate charged to the Company was 5%. As needed from time to time, the Company may draw on this line for use for general corporate purposes. As of December 31, 2012 and 2013, the Company has drawn $1,000,000 against the line of credit. The line of credit is subject to various financial covenants. As of December 31, 2013, the Company was not in compliance with one of these covenants, and the Bank waived the covenant violation. Prior to the most recent amendment on March 7, 2013, the Company was also not in compliance with certain other covenants. The September 28, 2012 amendment provided forbearance for the failure to comply with these certain covenants through November 30, 2012, and modified the covenants to include a requirement that the Company maintain account balances at the Bank totaling a minimum of $4,000,000 during the covered forbearance period. The December 6, 2012 amendment to the agreement extended the forbearance for the failure to comply with these certain covenants and the requirement for the Company to maintain account balances at the Bank totaling a minimum of $4,000,000 through December 31, 2012. In addition, pursuant to the March 7, 2013 amendment, the Bank waived the Company's existing breach of financial covenants under the credit agreement and the parties restructured the line of credit to provide that, among other things: (i) the revolving line of credit's maturity date was extended to March 7, 2015, (ii) the fee for the unused portion of the revolving line of credit was reduced from 0.375% to 0.250% per annum of the average unused portion of the revolving line of credit, (iii) the Company must continue to meet certain reporting requirements including providing financial statements and a certificate of compliance with the terms and conditions of the credit agreement by an authorized officer to the Bank within 45 days of the last day of each calendar quarter, provided that if the Company has less than $4,000,000 in its account at the Bank at any time during such calendar quarter, the Company must provide the financial statements and the certificate of compliance within 30 days of the end of such calendar quarter and provide a monthly report on revenues realized from private payors, (iv) the financial covenants were amended and restated to require the Company to maintain a ratio of quick assets to current liabilities of 1:50 to 1:00 and meet certain specified minimum adjusted earnings before interest, taxes, depreciation and amortization (“EBITDA”) requirements as defined in the amendment and measured on a monthly basis and (v) the Bank is granted certain additional inspection of books, records and collateral rights.

	23

As of December 31, 2012, the line of credit under the credit agreement was classified as a current liability of the Company on the accompanying balance sheet as the line of credit had a maturity date less than one year from December 31, 2012. As of December 31, 2013, the line of credit under the credit agreement was classified as a non-current liability of the Company on the accompanying balance sheet as the line of credit had a maturity date greater than one year from December 31, 2013.

In addition, we expect to use our capital to fund research and development and to make capital expenditures to keep pace with the expansion of our research and development programs and to scale up our commercial operations. The amount and timing of actual expenditures may vary significantly depending upon a number of factors, such as the progress of our product development, regulatory requirements, commercialization efforts, and the amount of cash used by operations. We expect that we will continue to generate revenue through our pharmacogenomic testing services and ResponseDX ^® testing services that we provide to pharmaceutical clients and to the users of our ResponseDX ^® testing services which include oncologists, pathologists, hospitals, and cancer care centers. These revenues are not guaranteed and are not expected to substantially offset the costs associated with our expansion efforts.

Following is a summary of recent events and the expected impact these events have had or may have on our liquidity and future realization of revenues.

Sales of Common Stock

Under the Company’s Articles of Incorporation, the Company has one class of common stock and its holders have no preemptive, subscription, redemption or conversion rights.

Common Stock Classified Outside of Stockholders’ Equity (Deficit)

March 2010 Private Placement

On March 5, 2010, the Company entered into a purchase agreement with certain affiliates of and funds managed by Lansdowne Partners Limited Partnership (“Lansdowne”), Greenway Capital Partners and Paragon Associates for the private placement of 3,005,349 newly-issued shares of the Company’s common stock at a per share price of $1.31. The closing of the sale of the shares occurred on March 5, 2010. In connection with the acquisition of the shares, the purchasers were granted certain preemptive rights permitting them to maintain their percentage ownership interests in connection with future issuances of the Company’s capital stock, subject to various exceptions and limitations. Lansdowne participated in the private placement by electing to exercise the preemptive rights granted to it pursuant to the purchase agreement by and between the Company and Lansdowne, dated July 22, 2009. Net proceeds received from this financing were approximately $3,879,403.

In connection with the private placement, the Company also entered into a registration rights agreement, dated March 5, 2010, with the purchasers pursuant to which it agreed to file, within 45 days of the closing of the private placement, a registration statement with the SEC to register the shares for resale, which registration statement was required to become effective within 120 days following the closing. The Company also granted certain "piggyback" registration rights to the purchasers which are triggered if the Company proposes to file a registration statement for its own account or the account of one or more shareholders until the earlier of the sale of all of the shares or the shares becoming eligible for sale under Rule 144(b)(1) without restriction.

Pursuant to the registration rights agreement, dated March 5, 2010, the Company filed a registration statement with the SEC to register the 3,005,349 shares sold to Lansdowne, Greenway and Paragon for resale, which became effective on May 19, 2010 and which registration statement remained effective as of December 31, 2013.

Under the registration rights agreements with the purchasers, the Company is obligated to use commercially reasonable efforts to (i) cause the registration statement described above to remain continuously effective and (ii) to maintain the listing of the Company’s common stock on NASDAQ or other exchanges, as defined, for a period that will terminate on the earlier of March 5, 2013 or the date on which the purchasers have sold all shares of common stock. The Company is also required to file with the SEC in a timely manner all reports and other documents required of the Company under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). In the event the Company fails to satisfy its obligations under the registration rights agreements, the Company would be in breach of said agreements, in which event, the purchases would be entitled to pursue all rights and remedies at law or equity including an injunction or other equitable relief. These registration rights agreements do not provide an explicitly stated or defined penalty due upon a breach. Because (i) the potential penalty for any breach of these registration rights agreement is not explicitly stated or defined, which prohibits the Company from applying the guidance of ASC 825-20-15, Registration Payment Arrangements and (ii) complying with all filing requirements under the Exchange Act as described above is not solely within the Company’s control, the Company is required to present the investment of approximately $3,879,403 in the Company’s common stock as common stock outside of stockholders’ equity in the accompanying consolidated balance sheet under ASC 480-10-S99-3, Classification and Measurement of Redeemable Securities .

On January 18, 2012, the Company removed the restrictions on 3,658,676 shares purchased by Lansdowne, of which 600,769 related to this offering, and reclassified the shares to common stock from common stock classified outside of equity (deficit). On March 5, 2013, the Company reclassified the remaining shares of common stock from this offering to common stock from common stock classified outside of equity (deficit). Therefore, as of December 31, 2012 and 2013, a total of $3,092,396 and $0 of common stock was classified outside of stockholders’ equity (deficit), respectively.

February 2012 Private Placement

	25

As of March 31, 2013, the Company has reclassified all of the February Shares to common stock from common stock classified outside of equity (deficit). Therefore, as of December 31, 2012 and 2013, a total of $3,183,328 and $0 of common stock was classified outside of stockholders’ equity (deficit), respectively.

September 2012 Private Placement

As of December 31, 2012, the Company has removed the restriction on 3,000,000 of the 8,000,000 September Shares and reclassified the shares to common stock from common stock classified outside of stockholders’ equity (deficit). Therefore, as of December 31, 2012 and 2013, a total of $5,500,000 of common stock relating to the 5,000,000 remaining restricted September Shares was classified outside of stockholders’ equity (deficit).

Comparison of years ended December 31, 2013 and 2012

As of December 31, 2013, we had $8,148,599 in cash and cash equivalents, net working capital of $9,693,565 and an accumulated deficit of $65,297,179.

As of December 31, 2012, we had $9,041,478 in cash and cash equivalents, net working capital of $9,718,816 and an accumulated deficit of $57,276,664.

Cash flows provided by operating activities

During the year ended December 31, 2013, the Company used cash flows in operating activities of $6,488,784 compared to $8,011,316 used in the year ended December 31, 2012. The reasons for the decrease in cash used in operating activities in the amount of $1,522,532 was due mainly to increases in accounts payable and accrued expenses offset by an increase in accounts receivable and a decrease in deferred revenue.

The increase in accounts receivable related mainly to elongated collection cycles for the Company’s Response:DX ^® receivables offset by an increase in the allowance for doubtful accounts. The increase in accounts payable and accrued expenses related primarily to the timing of the purchase of laboratory supplies to better match our immediate needs and the reduction of recruiting costs at year end. The decrease in deferred revenue related to certain services that had been paid in advance and for which all services have been provided.

Cash flows used in investing activities

Net cash used in investing activities was $807,874 and $956,560 for the years ended December 31, 2013 and 2012, respectively. These amounts were primarily attributable to the purchase of assets related to the ResponseDX: Tissue of Origin ^TM test and laboratory equipment in 2013 and the purchase and installation of software related to our Laboratory Information Management System (“LIMS”) in 2012.

Cash flows used in financing activities

Cash flows from financing activities for the years ended December 31, 2013 and 2012 provided net cash of $6,407,245 and $16,304,936, respectively, primarily relating to the sale of common stock net of payment of capital lease obligations.

We do not have any off-balance sheet arrangements.

Item 9A. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

Our management is responsible for establishing and maintaining adequate internal control over financial reporting for the Company. Under the supervision, and with the participation of our management, including the Principal Executive Officer and Principal Financial Officer, we have evaluated the effectiveness of our disclosure controls and procedures pursuant to Exchange Act Rules 13a-15 and 15d-15 as of the end of the period covered by this report. Based on that evaluation, our Principal Executive Officer and Principal Financial Officer have concluded that these disclosure controls and procedures were effective as of the end of the period covered by this report.

It should be noted that any system of controls and procedures, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. As a result, there can be no assurance that a control system will succeed in preventing all possible instances of error and fraud. Our disclosure controls and procedures are designed to provide reasonable assurance of achieving their objectives, and the conclusions of our Principal Executive Officer and the Principal Financial Officer are made at the “reasonable assurance” level.

Management’s Annual Report on Internal Control over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) promulgated under the Exchange Act. Our internal control system was designed to provide reasonable assurance to our management and board of directors regarding the preparation and fair presentation of published financial statements.

All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can only provide reasonable assurance with respect to financial statement preparation and presentation.

Management assessed the effectiveness of our internal control over financial reporting as of December 31, 2013. In making this assessment, it used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) in Internal Control—Integrated Framework (1992). Based on its assessment, management has concluded that, as of December 31, 2013, our internal control over financial reporting was effective based on those criteria.

This Annual Report on Form 10-K does not include an attestation report of our independent registered public accounting firm regarding internal control over financial reporting. Management’s report was not subject to attestation by our independent registered public accounting firm pursuant to an exemption for smaller companies under Section 989G of the Dodd-Frank Wall Street Reform and Consumer Protection Act.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting that occurred during the quarter ended December 31, 2013 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Item 9B. Other Information.

None.

Since November, 2009, Mr. Wurzer has served as Managing Director, Investments (November 2009 – October 2012), and as Senior Managing Director, Investments (October 2012 – present) at Connecticut Innovations (“CI”), a quasi-public authority responsible for venture capital technology investing and innovation development, where he is responsible for sourcing, analyzing and managing investments. Prior to joining CI, Mr. Wurzer was a consultant from January 2008 through November 2009 and served as Executive Vice President, Treasurer and Chief Financial Officer of CuraGen Corporation of Branford, Connecticut, from September 1997 through December 2007. From February 1994 until September 1997, Mr. Wurzer served as the Senior Vice President, Treasurer and Chief Financial Officer at Value Health, Inc. Mr. Wurzer is currently a member of the board of directors of Special Diversified Opportunities, Inc. (formerly known as Strategic Diagnostics Inc.) where he has served since February 2010. From July 2010 to December 2012 he also served as a member of the board of directors of DUSA Pharmaceuticals Inc.. Mr. Wurzer is also currently a member of the board of directors of Axerion Therapeutics, Inc., CyVek, Inc., EMME E2MS, NovaTract Surgical, Inc., SmartPay NewCo, LLC, Thetis Pharmaceuticals, LLC, and, ZetrOZ, Inc., which are privately held. Mr. Wurzer previously served on the 454 Life Sciences board of directors from June 2000 through May 2007. Mr. Wurzer received his B.B.A. in Accounting from the University of Notre Dame.

Mr. Wurzer has valuable experience as a director of diagnostics and life sciences companies which we believe is beneficial as a member of our Board. He has over thirty years of financial experience with growth-oriented companies, including direct involvement with raising capital, strategic transactions and mergers and acquisitions, for both start-up companies and publicly-held entities. This experience, coupled with his business and development background, enhances the Board and aids in its continued focus on, and oversight of, the Company’s growth.

The Nominating and Governance Committee has not yet made a proposal to the full board of directors regarding the composition of the directors to be nominated at the 2014 Annual Stockholders Meeting.

At the conclusion of this process, the Nominating and Governance Committee recommends to the full Board its proposed nominees and the full Board will make a final determination of an appropriate slate of directors to be nominated at the 2014 Annual Stockholders Meeting.

Board of Directors Meetings and Attendance

Our board of directors met twelve times during the fiscal year ended December 31, 2013, either in person or by teleconference. During 2013, each of our directors attended at least 75% of the aggregate of the number of meetings of the Board and of committees of the Board on which he served during fiscal 2013, with the exception of Michael Serruya.

Our corporate governance guidelines provide that directors are strongly encouraged to attend the annual meeting of stockholders. All of our current directors attended the 2013 annual meeting of our stockholders.

Board Composition

The Board of Directors seeks to ensure that the Board is composed of members whose particular experience, qualifications, attributes and skills, when taken together, will allow the Board to satisfy its oversight responsibilities effectively.

How Directors are Chosen

The Nominating and Governance Committee is responsible for assisting the Board in identifying individuals qualified to become Board members and recommending director nominees to the Board for each annual meeting of stockholders. It is the Nominating and Governance Committee’s policy to consider candidates recommended by stockholders, Company management or any other Board members. All candidate recommendations submitted by stockholders will be considered in the same manner and under the same process as any other candidate recommendations submitted from other sources.

The Nominating and Governance Committee considers the qualifications of candidates based upon its charter and the Company’s corporate governance guidelines. The Nominating and Governance Committee selects individuals as director nominees who have the highest personal and professional integrity, who have demonstrated exceptional ability and judgment and who would be most effective, in conjunction with the other members of the Board, in collectively serving the long-term interests of the stockholders, and all other factors it considers appropriate. Members of the Board may recommend potential candidates to the Board for consideration. The Nominating and Governance Committee does not have a formal policy with regard to the consideration of diversity in identifying director candidates. However, the Nominating and Governance Committee believes that having diversity amongst Board members enhances the Board’s ability to make fully informed, comprehensive decisions and demonstrates leadership with respect to the Company’s initiatives to recruit and retain the best employees. As a result, the Nominating and Governance Committee believes that the Board should be comprised of a well-balanced group of individuals with diverse backgrounds, experiences, ages, races, genders and national origins as well as differences of viewpoint, professional experience, financial, business, academic, public sector and other expertise, education, skill and other individual qualities and attributes that contribute to board heterogeneity. The Nominating and Governance Committee has authority to retain search firms to assist in identifying and evaluating director candidates and to approve fees and retention terms for such advisors. After conducting an initial evaluation of a candidate, the Nominating and Governance Committee may interview that candidate if it believes the candidate might be suitable to be a director and may also ask the candidate to meet with other directors and members of management. If the Nominating and Governance Committee believes a candidate would be a valuable addition to the Board, it will recommend to the full Board that candidate’s election.

Leadership Structure

Chairman and Chief Executive Officer

The Board does not have a prescribed policy on whether the roles of the Chairman of the Board and the Chief Executive Officer should be separate or combined. The Board periodically evaluates its leadership structure to determine what it believes is the optimal structure at any point in time.

Mr. Bologna currently serves as the Chairman of the Board and Chief Executive Officer. In these roles, Mr. Bologna has the principal authority for supervising the business and affairs of the Company, and is responsible generally for assuring that policy decisions of the Board are implemented as adopted. As the Chairman, Mr. Bologna provides leadership to the Board and works with the Board to define its structure and activities in the fulfillment of its responsibilities. The Chairman is also responsible for chairing Board meetings and setting the agenda for these meetings. Each director also may suggest items for inclusion on the agenda and may raise at any Board meeting subjects that are not on the agenda for that meeting.

We believe that our current leadership structure is appropriate for the Company, in that the combined role of Chairman and Chief Executive Officer promotes unified leadership and direction, allowing for a single, clear focus for management to execute the Company’s strategy and business plan while contributing to a more efficient and effective Board.

Lead Director

The Lead Director primarily serves as a liaison between the Board and Chief Executive Officer, assisting the Board to maintain an open and active communication with the Chief Executive Officer. The Lead Director also facilitates board discussions, including helping directors reach consensus, and keeping Board matters on track. The Lead Director has the authority to call executive sessions and to preside over executive sessions and any other meeting of the Board that the Chief Executive Officer is not present.

Committees

Our Board has three standing committees, each of which is comprised solely of independent directors with a different committee chair, each as described below. In addition, in its discretion, the Board may authorize and appoint special committees with such duties and powers as are deemed necessary and appropriate by the Board. For example, in connection with the consideration of financing transactions in 2011 and 2012, our Board formed a Special Financing and Strategy Committee authorized to make recommendations to the Board with regard to financing alternatives and proposals. We believe that experienced independent directors, separate committee chairs and, where necessary, special committee support provide an effective leadership structure for the Company.

Oversight of Risk Management

It is management’s responsibility to manage risk and bring to the Board’s attention the most material risks to the Company. It is the Board’s responsibility to oversee management in this effort. The Board has oversight responsibility of the processes established to report and monitor systems for material risks applicable to the Company. In exercising its oversight, the Board has allocated some areas of focus to its committees and has retained areas of focus for itself, as described below. The Audit Committee regularly reviews financial risk, such as accounting, finance, internal controls and other risk management functions. The Nominating and Governance Committee considers risks related to succession planning and oversees the appropriate allocation of responsibility for risk oversight among the committees of the Board. The Compensation Committee considers risks related to the attraction and retention of talent and risks relating to the design of compensation programs and arrangements and has determined that the Company’s compensation programs are not reasonably likely to have a material adverse effect on the Company. The Compensation Committee also reviews compensation and benefits plans affecting employees in addition to those applicable to executive officers. Oversight responsibility for compliance risk is shared among the Board committees. The full Board considers strategic risks and opportunities and regularly receives detailed reports from the committees regarding risk oversight in their areas of responsibility.

Communications Between Stockholders and Board of Directors

Generally, stockholders who have questions or concerns should contact our Corporate Headquarters to the attention of Kevin R. Harris, Vice President and Chief Financial Officer, at (323) 224-3900. However, any stockholder who wishes to address questions regarding our business directly with the Board, or any individual director, should direct his or her questions to the Board members via e-mail at RGDX@openboard.info. Communications will be distributed to the Board, or to any individual director or directors as appropriate, depending on the facts and circumstances outlined in the communications. Items that are unrelated to the duties and responsibilities of the Board, such as junk mail and mass mailings, resumes and other forms of job inquiries, surveys and solicitations or advertisements, may be excluded. In addition, any material that is unduly hostile, threatening, or illegal in nature may be excluded, provided that any communication that is filtered out will be made available to any outside director upon request.

Board Committees

In order to fulfill its responsibilities, our Board has delegated certain authority to its committees. Currently, there are three standing committees: Audit Committee, Compensation Committee and Nominating and Governance Committee.

A brief description of each of the Board committees and their functions is described below. Additional information about the committees can be found in the committee charters, which are available on the Investor Relations section of our website at www.responsegenetics.com. Printed copies of these charters may be obtained without charge by writing to the Corporate Secretary.

Our Board has determined that all of the members of each of the Board’s three standing committees are independent as defined under the rules of the NASDAQ Stock Market, including, in the case of all members of the Audit Committee, the independence requirements contemplated by Rule 10A-3 under the Securities and Exchange Act of 1934.

Stockholders should understand that this designation is a disclosure requirement of the SEC related to Mr. Calhoun’s experience and understanding with respect to certain accounting and auditing matters. The designation does not impose upon Mr. Calhoun any duties, obligations or liability that are greater than are generally imposed on him as a member of the Audit Committee and the Board, and his designation as an audit committee financial expert pursuant to this SEC requirement does not affect the duties, obligations or liability of any other member of the Audit Committee or the Board.

Report of Audit Committee

The Audit Committee of the Board of Directors, which consists entirely of directors who meet the independence and experience requirements of The NASDAQ Stock Market, has furnished the following report:

The Audit Committee assists the Board in overseeing and monitoring the integrity of our financial reporting process, compliance with legal and regulatory requirements and the quality external audit processes.

The Audit Committee is responsible for overseeing our overall financial reporting process, and for the appointment, compensation, retention, and oversight of the work of BDO USA, LLP. In fulfilling its responsibilities for the financial statements for fiscal year 2013, the Audit Committee took the following actions:

Discussed with BDO USA, LLP the matters required to be discussed by Public Company Accounting Oversight Board Auditing Standard No. 16, Communications with Audit Committees; and

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), requires the Company’s directors and executive officers, and any persons who own more than ten percent of a registered class of the Company’s equity securities, to file with the SEC initial reports of ownership and reports of changes in ownership of Common Stock and other equity securities of the Company. Directors, executive officers and greater than ten percent stockholders are required by SEC regulations to furnish the Company with copies of all Section 16(a) forms they file. Based solely on its review of the copies of such forms and written representations from certain reporting persons, the Company believes that all filing requirements applicable to its directors and executive officers have been complied with during 2013.

Corporate Code of Conduct and Ethics

We have adopted a Corporate Code of Conduct and Ethics that applies to all of our officers, directors and employees, including our Chief Executive Officer and Chief Financial Officer.

On July 30, 2012, the board of directors of the Company had voted to keep the annual cash retainer portion of non-employee directors’ compensation the same in 2012 as it was in 2011. On April 12, 2011, the board of directors revised its compensation policy to move from a retainer and committee fees program to a fixed annual retainer and committee retainer board compensation policy. Under the terms of this policy, each of our non-employee directors will receive the following, as applicable:

Annual Retainer	$	32,000

All directors also receive an annual grant of options to purchase a number of shares of our common stock at an exercise price equal to the fair market value of our common stock on the date of grant as recommended by the Compensation Committee and approved by the full Board. The one-time option granted to newly elected directors is typically for the same number of shares as the annual option grant to directors. On November 20, 2013, our Compensation Committee recommended and the full Board approved an annual grant of options to purchase 27,000 shares of our common stock at an exercise price equal to the fair market value of our common stock on the date of grant to each director of the Company except for the Lead Director for whom the Compensation Committee recommended and the full Board approved an option to purchase 33,750 shares of our common stock at an exercise price equal to the fair market value of our common stock on such date of grant. The Compensation Committee also recommended and the full Board approved a one-time grant of option to purchase 27,000 shares of our common stock to each of our two newly elected directors.

Item 13. Certain Relationships and Related Transactions, and Director Independence.

DIRECTOR INDEPENDENCE

Our Board of Directors has reviewed the materiality of any relationship that each of our directors has with the Company, either directly or indirectly. Based upon this review, our Board has determined that the following members of the Board are “independent directors” as defined by The NASDAQ Stock Market: Kirk K. Calhoun, Sam Chawla, David R. Schreiber, Richard van den Broek and David Wurzer.

RELATED PARTY TRANSACTIONS

The Board of Directors has adopted a written policy requiring that any transaction involving the Company in which one of our directors, executive officers, or greater than five percent stockholders, or the immediate family members of any of the foregoing persons, has a direct or indirect material interest (a “related party transaction”), be approved or ratified by a majority of the full Board or by a designated committee of the Board.

The Board has designated the Audit Committee as having responsibility for reviewing and approving, in advance, all such transactions. In determining whether to approve or ratify any such transaction, the Audit Committee must consider, in addition to other factors deemed appropriate, whether the transaction is in the best interests of the Company and is on terms comparable to those involving unrelated parties. No member of the Audit Committee may participate in any review, approval or ratification of any related party transaction if he or she, or his or her immediate family member, has a direct or indirect material interest in the transaction.

	41

There have been no related party transactions between January 1, 2013 and the date of filing of this Annual Report on Form 10-K, and there is currently no proposed transaction involving the Company that would constitute a related party transaction.

Item 14. Principal Accounting Fees and Services.

INDEPENDENT REGISTERED PUBLIC ACCOUNTANTS

Policy on Audit Committee Pre-Approval of Audit and Permissible

Non-audit Services of Independent Auditors

Consistent with SEC policies regarding auditor independence, the Audit Committee has responsibility for appointing, setting compensation and overseeing the work of the independent auditor. In recognition of this responsibility, the Audit Committee has established a policy to pre-approve all audit and permissible non-audit services provided by the independent auditor.

Prior to engagement of the independent auditor for the next year's audit, management will submit an aggregate of services expected to be rendered during that year for each of four categories of services to the Audit Committee for approval.

Audit services include audit work performed in the preparation of financial statements, as well as work that generally only the independent registered public accounting firm can reasonably be expected to provide, including comfort letters, statutory audits, and attest services and consultation regarding financial accounting and/or reporting standards.

Audit-Related services are for assurance and related services that are traditionally performed by the independent registered public accounting firm, including due diligence related to mergers and acquisitions, employee benefit plan audits, and special procedures required to meet certain regulatory requirements.

Tax services include all services performed by the independent auditor's tax personnel except those services specifically related to the audit of the financial statements, and includes fees in the areas of tax compliance, tax planning, and tax advice.

Other Fees are those associated with services not captured in the other categories. The Company generally does not request such services from the independent auditor.

Prior to engagement, the Audit Committee pre-approves these services by category of service. The fees are budgeted and the Audit Committee requires the independent auditor and management to report actual fees versus the budget periodically throughout the year by category of service. During the year, circumstances may arise when it may become necessary to engage the independent auditor for additional services not contemplated in the original pre-approval. In those instances, the Audit Committee requires specific pre-approval before engaging the independent auditor.

The Audit Committee may delegate pre-approval authority to one or more of its members. The member to whom such authority is delegated must report, for informational purposes only, any pre-approval decisions to the Audit Committee at its next scheduled meeting.

In the event the stockholders fail to ratify the appointment, the Audit Committee will consider whether or not to retain that firm. Even if the selection is ratified, the Audit Committee in its discretion may direct the appointment of a different independent registered public accounting firm at any time during the year if it determines that such a change would be in the best interests of the Company and its stockholders.

The affirmative vote of a majority of the shares cast affirmatively or negatively at the annual meeting is required to ratify the appointment of the independent public accountants.

Audit Services And Fees

The professional services provided by BDO USA, LLP and the aggregate fees for those services rendered during the years ended December 31, 2013 and 2012 were as follows:

	2013		2012
Audit Fees	$	250,816	$	312,922

Response Genetics, Inc.

Los Angeles , California

We have audited the accompanying consolidated balance sheets of Response Genetics, Inc. as of December 31, 2013 and 2012 and the related consolidated statements of operations and comprehensive loss, stockholders’ equity (deficit), and cash flows for each of the two years in the period ended December 31, 2013. In connection with our audits of the financial statements, we have also audited the financial statement schedule listed in the accompanying index. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements and schedule based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and schedule. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Response Genetics, Inc. at December 31, 2013 and 2012, and the results of its operations and its cash flows for each of the two years in the period ended December 31, 2013 , in conformity with accounting principles generally accepted in the United States of America.

Also, in our opinion, the financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, present fairly, in all material respects, the information set forth therein.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Organization, Operations and Basis of Accounting

Response Genetics, Inc. (the “Company”) was incorporated in the State of Delaware on September 23, 1999 as Bio Type, Inc. for the purpose of providing unique molecular profiling services of tumor tissue that has been formalin-fixed and embedded in paraffin wax. In August 2000, the Company changed its name to Response Genetics, Inc.

The Company is a life science company engaged in the research, development, marketing and sale of pharmacogenomic tests for use in the treatment of cancer. Pharmacogenomics is the science of how an individual’s genetic makeup relates to drug response. Tests based on pharmacogenomics facilitate the prediction of a response to drug therapy or survival following surgery based on an individual’s genetic makeup. In order to generate pharmacogenomic information from patient specimens for these tests, the Company uses proprietary enabling methods for maximizing the extraction and analysis of nucleic acids and, therefore, accessing the genetic information available from each patient sample. The Company’s platforms include analysis of single biomarkers using the polymerase chain reaction method as well as global gene interrogation using microarray methods and fluorescence in situ hybridization (“FISH”) from paraffin or frozen tissue specimens. The Company primarily derives its revenue from the sale of its ResponseDX ^® diagnostic testing products and by providing pharmacogenomic clinical trial testing services to pharmaceutical companies in the United States, Asia and Europe.

The Company’s goal is to provide cancer patients and their physicians with a means to make informed, individualized treatment decisions based on genetic analysis of tumor tissues. The Company’s pharmacogenomic analysis of clinical trial specimens for the pharmaceutical industry may provide data that will lead to a better understanding of the molecular basis for response to specific drugs and, therefore lead to individualized treatment.

Since its inception, the Company has devoted substantial effort in developing its product and has incurred losses and negative cash flows from operations, and at December 31, 2013 has an accumulated deficit of $ 65,297,179 . The Company is forecasting continued losses and negative cash flows as it funds its sales and marketing activities and research and development programs.

Based on the Company’s current operating plan which includes various assumptions concerning the level and timing of cash receipts from product sales and cash outlays for operating expenses and capital expenditures, management believes that existing cash and cash equivalents will be sufficient to meet the Company’s working capital requirements through the next twelve months. The Company’s ability to successfully carry out its business plan is primarily dependent upon its ability to (1) obtain sufficient additional capital at acceptable costs, (2) attract and retain knowledgeable workers, and (3) generate significant revenues. The Company expects to seek additional financing and/or strategic investments; however, there can be no assurance that any additional financing or strategic investments will be available on acceptable terms, if at all.

If events or circumstances occur such that the Company does not meet its operating plan as expected, the Company will most likely be required to reduce certain discretionary spending, which could have a material adverse effect on the Company’s ability to achieve its intended business objectives. No adjustments have been made to the accompanying financial statements to reflect any of the matters discussed above.

The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States ("GAAP"). The preparation of financial statements in conformity with GAAP requires management to make judgments, assumptions and estimates that affect the amounts reported in the Company's consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates.

2. Summary of Significant Accounting Policies

Basis of Consolidation

The consolidated financial statements include the accounts of the Company and its wholly owned subsidiary, Response Genetics, Ltd., a Scottish corporation (the “Subsidiary”), which was incorporated in November 2006. The Subsidiary had no employees or active operations during 2012 and 2013. All significant intercompany transactions and balances have been eliminated in consolidation.

Cash and Cash Equivalents

The Company considers all highly liquid investments with a maturity at date of purchase of three months or less to be cash equivalents. The carrying value of cash equivalents approximates fair value due to the short-term nature and liquidity of these instruments. The Company’s cash equivalents are comprised of cash on hand, deposits in banks and money market investments.

Accounts Receivable

Pharmaceutical Accounts Receivable

The Company invoices its clients as specimens are processed and any other contractual obligations are met. The Company’s contracts with clients typically require payment within 45 days of the date of invoice. The Company maintains allowances for doubtful accounts for estimated losses resulting from the inability of its clients to make required payments. The Company specifically analyzes accounts receivable and historical bad debts, client credit, current economic trends and changes in client payment trends when evaluating the adequacy of the allowance for doubtful accounts. Account balances are charged-off against the allowance when it is probable the receivable will not be recovered. To date, the Company’s clients have primarily been large pharmaceutical companies. As a result, bad debts from clinical accounts receivable to date have been minimal. Pharmaceutical company accounts receivable as of December 31, 2012 and 2013 were $ 2,549,665 and $ 1,892,384 respectively. There were no allowances for doubtful accounts recorded against these pharmaceutical accounts receivable at December 31, 2012 and 2013.

ResponseDX ^® Accounts Receivable

ResponseDX ^® accounts receivable are recorded from two primary payors: Medicare and third party and private payors (“Private Payors”). ResponseDX ^® accounts receivable are recorded at established billing rates less an estimated billing adjustment, based on reporting models utilizing historical cash collection percentages and updated for current effective reimbursement factors. Management performs ongoing valuations of accounts receivable balances based on management’s evaluation of historical collection experience and industry trends. Based on the historical experience for our Medicare and Private Payor accounts, management has determined, based on a detailed analysis, that accounts receivable associated with certain billings are unlikely to be collected. Therefore, the Company has recorded an allowance for doubtful accounts of $ 991,990 and $ 2,404,659 as of December 31, 2012 and 2013. The Company’s bad debt expense for the years ended December 31, 2012 and 2013 was $ 1,351,592 and $ 3,165,918 , respectively.

ResponseDX ^® accounts receivable consisted of the following:

	December 31,		December 31,
	2012		2013
Net Medicare receivable	$	890,936	$	2,422,611
Net Private Payor receivable		2,924,412		4,315,587
		3,815,348		6,738,198
Allowance for doubtful accounts		(991,990)		(2,404,659)
	$	2,823,358	$	4,333,539

As more fully discussed in Note 3 Property and Equipment and Intangible Assets, the Company acquired accounts receivable in August 2013 that had a valuation of $ 257,000 . All of these receivables were collected by December 31, 2013.

As part of its process for evaluating the collectability of aged accounts receivable management identified delays in the Medicare administrative law appeal process for aged accounts receivable that would extend the process significantly (up to two years). Accordingly, management considered this factor in estimating the allowance for doubtful accounts and concluded that an additional allowance of approximately $ 690,000 was necessary as of December 31, 2013 to reserve for the balance of Medicare accounts receivable as of December 31, 2013 that were going to age greater than one year shortly after December 31, 2013.

Property and Equipment and Intangible Assets

Property and equipment are carried at cost less accumulated depreciation and amortization. Depreciation and amortization are calculated using the straight-line method over the estimated useful lives of the assets. The Company has determined the estimated useful lives of its property and equipment, as follows:

Laboratory equipment		5 to 7 years
Furniture and equipment		5 to 7 years
Purchased and internally-developed software		3 to 5 years
Leasehold improvements		Shorter of the useful life (5 to 7 years) or the lease term

Maintenance and repairs are charged to expense as incurred. The cost and accumulated depreciation of assets sold or otherwise disposed of are removed from the related accounts and the resulting gain or loss is reflected in the statements of operations. The Company has capitalized costs related to the development of database software (see Note 3). The portion of this database placed into service is amortized in accordance with ASC 350-40, Internal-Use Software . The amortization period is five years using the straight-line method.

Revenue Recognition

Pharmaceutical Revenue

Revenues that are derived from testing services provided to pharmaceutical companies are recognized on a contract specific basis pursuant to the terms of the related agreements. Revenue is recognized in accordance with ASC 605, Revenue Recognition, which requires that four basic criteria must be met before revenue can be recognized: (1) persuasive evidence that an arrangement exists; (2) delivery has occurred and title and the risks and rewards of ownership have been transferred to the client or services have been rendered; (3) the price is fixed or determinable; and (4) collectability is reasonably assured.

Revenues are recorded on an accrual basis as the contractual obligations are completed and as a set of assays is processed through the Company’s laboratory under a specified contractual protocol and are recorded on the date the tests are resulted. Certain contracts have minimum assay requirements that, if not met, result in payments that are due upon the completion of the designated period. In these cases, revenues are recognized when the end of the specified contract period is reached.

On occasion, the Company may enter into a contract that requires the client to provide an advance payment for specimens that will be processed at a later date. In these cases, the Company records this advance as deferred revenue and recognizes the revenue as the specimens are processed or at the end of the contract period, as appropriate.

The Company recorded revenue from pharmaceutical clients of $ 6,852,536 and $ 7,789,985 for the years ended December 31, 2012 and 2013, respectively.

ResponseDX ^® Revenue

Revenues that are derived from ResponseDX ^® testing services are recognized in accordance with ASC 605, Revenue Recognition , which requires that four basic criteria be met before revenue can be recognized: (1) persuasive evidence that an arrangement exists; (2) delivery has occurred and title and the risks and rewards of ownership have been transferred to the client or services have been rendered; (3) the price is fixed or determinable; and (4) collectability is reasonably assured. We record revenues when our tests have confirmed results which are evidence that the services have been performed.

Revenues are recorded on an accrual basis as the contractual obligations are completed and as a set of assays is processed through our laboratory under a specified contractual protocol.

ResponseDX ^® private payor and Medicare revenues are recorded at established billing rates less an estimated billing adjustment, based on reporting models utilizing historical cash collection percentages and updated for current effective reimbursement factors. The Company’s Medicare provider number allows it to invoice and collect from Medicare. The Company’s invoicing to Medicare is primarily based on amounts allowed by Medicare for the service provided as defined by Common Procedural Terminology (“CPT”).

Medicare reimbursement rates are subject to regulatory changes and government funding restrictions. In January 2013, the annual Medicare fee schedules update was announced which included proposed changes to Medicare reimbursement rates that significantly reduced the reimbursement rates for certain of the testing services the Company provides. The Company participated with other impacted organizations to provide guidance to the local Medicare Administrative Contractor (“MAC”) that resulted in the local MAC updating certain pricing through September 2013 which reflected an increase in many of the tests originally priced in January 2013. In addition, on October 1, 2013, the Centers for Medicare and Medicaid Services (“CMS”) issued fees for some, but not all, of the CPT codes used by the Company. As a result of these CPT code changes and Medicare price changes, the Company has experienced a departure from its normal reimbursement patterns with Medicare and other payors. Specifically, the Company has experienced delays in certain reimbursements for services and an increase in initial denials of claims for certain services provided. Accordingly, the Company re-evaluated the assumptions employed in its model for estimating revenue to be recognized for ResponseDX ^® testing. The Company views the code and price changes described above as affecting only the assumptions the Company used in pricing its services. The nature of the testing the Company provides, the evidence it gathers to establish the creditworthiness of its payors and the delivery method of its services have not changed from prior periods, and there are no indicators that these assumptions require change.

The Company performed an analysis that considered its historical patterns of revenue by payor in conjunction with the fluctuations it experienced in the twelve months ended December 31, 2013 to arrive at the revenue recorded during 2013. The Company believes that the changes in CPT codes and pricing that are causing confusion and erratic payment experience in the payor community will take some time to resolve. The time needed for resolution will depend upon Medicare and the local MAC releasing additional pricing changes and potentially, revisions to previously revised prices, and upon the private payor community adopting the new CPT codes and some level of revised pricing. Accordingly, the Company’s revenue recognition estimates could be materially affected in future periods as pricing and payment patterns change and develop, and the Company may be materially affected by future or retroactive price changes.

The following details ResponseDX ^® revenue for the years ended December 31, 2012 and 2013:

	Year Ended December 31,
	2012		2013

Net Medicare revenue	$	5,405,393	$	4,521,732

Cost-Containment Measures

Both government and private pay sources have instituted cost-containment measures designed to limit payments made to providers of health care services, which include diagnostic test providers such as the Company, and there can be no assurance that future measures designed to limit payments made to providers will not adversely affect the Company.

Regulatory Matters

A portion of the Company’s revenues are derived from Medicare reimbursement. Laws and regulations governing Medicare programs are complex and subject to interpretation, and the Company may be adversely affected by future governmental investigations, lawsuits or private actions which include mandatory damages, fines, penalties, criminal charges, loss or suspension of licenses and/or suspension or exclusion from Medicare and certain other governmental programs. The Company believes that it is in compliance with all applicable laws and regulations and is not aware of any pending or threatened investigations involving allegations of potential wrongdoing.

Cost of Revenue

Cost of revenue represents the cost of materials, direct labor, royalties, costs associated with processing tissue specimens including pathological review, staining, microdissection, paraffin extraction, reverse transcription polymerase chain reaction, fluorescence in situ hybridization (“FISH”), quality control analyses, license fees and delivery charges necessary to render an individualized test result. Costs associated with performing tests are recorded as the tests are processed.

License Fees

The Company has licensed technology for the extraction of ribonucleic acid (“RNA”) from formalin-fixed, paraffin-embedded tumor specimens from the University of Southern California (“USC”). Under the terms of the license agreement, the Company is required to pay royalties to USC calculated as a fixed percentage of the revenue the Company generates by using this technology. The Company also maintains a non-exclusive license to use certain patents related to the polymerase chain reaction (“PCR”) of Roche Molecular Systems, Inc. (“Roche”). The Company pays Roche a royalty fee based on revenue that the Company generates through use of this technology. The Company accrues for such royalties at the time revenue is recognized. Such royalties are included in cost of revenues in the accompanying statements of operations.

Research and Development

The Company expenses costs associated with research and development activities as incurred. Research and development costs are expensed as incurred and classified as research and development costs. Research and development costs include employee costs (salaries, payroll taxes, benefits, and travel), equipment depreciation and warranties and maintenance, laboratory supplies, primers and probes, reagents, patent costs and occupancy costs.

Line of Credit

On July 14, 2011 , the Company entered into a line of credit agreement with Silicon Valley Bank (the “Bank”). The agreement has been amended most recently on March 7, 2013. The line of credit is collateralized by the Company’s pharmaceutical , Private Payor and Medicare receivables. The amended maximum amount that can be borrowed from the credit line is $ 2,000,000 . As of December 31, 2013, the amount the Company can draw from the loan was $ 1,000,000 calculated as the lesser of (i) the Company’s calculated borrowing base, which was 80 % of certain of the Company’s accounts receivable, or (ii) the amount available under the credit line. As of December 31, 2013, the interest fees associated with this line of credit were set at the prime rate plus 1 %. During 2012 and 2013, the rate charged to the Company was 5 %. As needed from time to time, the Company may draw on this line for use for general corporate purposes. As of December 31, 2012 and December 31, 2013, the Company has drawn $ 1,000,000 against the line of credit. The line of credit is subject to various financial covenants. As of December 31, 2013, the Company was not in compliance with one of these covenants, and the Bank waived the covenant violation. Prior to the most recent amendment on March 7, 2013, the Company was also not in compliance with certain other covenants . The September 28, 2012 amendment provided forbearance for the failure to comply with these certain covenants through November 30, 2012, and modified the covenants to include a requirement that the Company maintain account balances at the Bank totaling a minimum of $ 4,000,000 during the covered forbearance period. The December 6, 2012 amendment to the agreement extended the forbearance for the failure to comply with these certain covenants and the requirement for the Company to maintain account balances at the Bank totaling a minimum of $ 4,000,000 through December 31, 2012. In addition, pursuant to the March 7, 2013 amendment, the Bank waived the Company's existing breach of financial covenants under the credit agreement and the parties restructured the line of credit to provide that, among other things: (i) the revolving line of credit's maturity date was extended to March 7, 2015 , (ii) the fee for the unused portion of the revolving line of credit was reduced from 0.375 % to 0.250 % per annum of the average unused portion of the revolving line of credit, (iii) the Company must continue to meet certain reporting requirements including providing financial statements and a certificate of compliance with the terms and conditions of the credit agreement by an authorized officer to the Bank within 45 days of the last day of each calendar quarter, provided that if the Company has less than $4,000,000 in its account at the Bank at any time during such calendar quarter, the Company must provide the financial statements and the certificate of compliance within 30 days of the end of such calendar quarter and provide a monthly report on revenues realized from private payors, (iv) the financial covenants were amended and restated to require the Company to maintain a ratio of quick assets to current liabilities of 1:50 to 1:00 and meet certain specified minimum adjusted earnings before interest, taxes, depreciation and amortization (“EBITDA”) requirements as defined in the amendment and measured on a monthly basis and (v) the Bank is granted certain additional inspection of books, records and collateral rights .

From time to time, the Company’s calculated borrowing base under its Bank line of credit may decrease to a level where the Company is in an over-advance position in which case the Company will be required to repay any outstanding amounts greater than the calculated borrowing base for such covered period back to the Bank immediately. The Company will be able to draw down on the credit line again with respect to such paid back amount once the Company is in compliance with the borrowing base requirement. This occurred on one occasion during the second quarter of 2012 based on the May 2012 borrowing base, as a result of which the Company was required to repay $ 298,000 to the Bank. The Company drew down the same amount one week later once the June 2012 borrowing base was determined to be sufficiently higher than the May 2012 borrowing base, thereby giving the Company the capacity to borrow such additional amount.

Income Taxes

Deferred tax assets and liabilities are determined based on differences between the financial reporting and tax basis of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized.

ASC 740, Income Taxes , clarifies the accounting for uncertainty in income taxes recognized in financial statements and requires the impact of a tax position to be recognized in the financial statements if that position is more likely than not of being sustained by the taxing authority. As of December 31, 2012 and 2013, the Company does not have a liability for unrecognized tax benefits. The Company recognizes interest and penalties associated with tax matters as part of the income tax provision, and the Company includes accrued interest and penalties with the related tax liability in the balance sheet. For the years ended December 31, 2012 and 2013, there were no interest or penalties recorded on the consolidated statement of operations.

Stock-Based Compensation

The Company accounts for stock-based compensation in accordance with ASC 718, Stock Compensation , Share-Based Payment . Stock-based compensation expense for all stock-based compensation awards granted is based on the grant-date fair value estimated in accordance with the provisions of ASC 718. The Company recognizes these compensation costs on a straight-line basis over the requisite service period of the award, which is generally the option vesting period. As further described in Note 7, certain awards granted to Thomas A. Bologna, the Company’s Chairman and Chief Executive Officer, were recognized based on an accelerated vesting basis triggered by market conditions rather than a straight-line basis.

The Company accounts for equity instruments issued to non-employees in accordance with ASC 505, Equity . Under ASC 505, stock option awards issued to non-employees are measured at fair value using the Black-Scholes option-pricing model and recognized pursuant to a performance model.

Management Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates in these consolidated financial statements have been made for revenue, allowances for doubtful accounts, impairment of long-lived assets, depreciation of property and equipment and stock-based compensation. Actual results could differ materially from those estimates.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

2. Summary of Significant Accounting Policies - (continued)

Long-lived Assets

Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The Company evaluates potential impairment by comparing the carrying amount of the asset with the estimated undiscounted future cash flows associated with the use of the asset and its eventual disposition. Should the review indicate that the assets cost is not recoverable, the carrying value of the asset would be reduced to its fair value, which is measured by future discounted cash flows.

Foreign Currency Translation

The financial position and results of operations of the Company’s foreign subsidiary are determined using local currency as the functional currency. Assets and liabilities of these operations are translated at the exchange rate in effect at each period-end. Statement of Operations amounts are translated at the average rate of exchange prevailing during the period. Translation adjustments arising from the use of differing exchange rates from period to period are included in accumulated other comprehensive loss in stockholders’ equity (deficit).

Comprehensive Loss

The components of comprehensive loss are net loss and foreign currency translation adjustments for the years ended December 31, 2012 and 2013.

Fair Value of Financial Instruments

Cash and cash equivalents are stated at cost, which approximates fair market value. Cash equivalents consist of money market accounts, with fair values estimated based on quoted market prices. Debt balances are stated at historical amounts less principal payments, which approximate fair market value. The Company believes interest rates in its debt agreements are commensurate with lender risk profiles for similar companies.

Advertising costs

The Company markets its services through its advertising activities in trade publications and on the internet. Advertising costs are included in selling and marketing expenses on the statements of operations and are expensed as incurred. Advertising costs for the years ended December 31, 2012 and 2013 were $ 13,788 and $ 16,677 , respectively.

Reclassifications

Prior year amounts in the consolidated financial statements have been reclassified to conform with the current year presentation. Reclassified amounts had no impact on the Company’s net losses for the year ended December 31, 2012 or 2013.

2. Summary of Significant Accounting Policies - (continued)

Many of the supplies and reagents used in the Company’s testing process are procured from a limited number of suppliers. Any supply interruption or an increase in demand beyond the suppliers’ capabilities could have an adverse impact on the Company’s business. Management believes it can identify alternative sources, if necessary, but it is possible such sources may not be identified in sufficient time to avoid an adverse impact on its business. Refer also to Note 6 for further discussion regarding these supply agreements. The Company purchases certain laboratory supplies and reagents primarily from a limited number of suppliers. The Company made approximately 71 % of its reagent purchases from two suppliers during the year ended December 31, 2012 and made approximately 87 % of its reagent purchases from four suppliers during the year ended December 31, 2013.

Less: Accumulated amortization		(95,652)		(228,725)
Total intangible assets, net	$	575,409	$	767,223

Intangible assets are carried at the cost to obtain them. Internally developed intangible assets are amortized using the straight-line method over the estimated useful life of five years. At December 31, 2012, the Company had not yet begun amortizing purchased software costs related to its new Laboratory Information Management System (“LIMS”). During the first quarter of 2013, the Company deployed LIMS and began amortizing the cost. Amortization expense, included in cost of revenue, general and administrative expenses, and research and development expenses for the years ended December 31, 2012 and 2013 was $ 470,054 and $ 632,976 , respectively.

On August 23, 2013, the Company entered into an asset purchase agreement (the “Pathwork Purchase Agreement”) with Pathwork (assignment for the benefit of creditors), LLC (“Seller”), pursuant to which the Company acquired substantially all of the assets of Pathwork Diagnostics, Inc. (“Pathwork”), which had previously assigned all of its assets to Seller for the benefit of its creditors pursuant to a General Assignment, dated as of April 2, 2013. Pursuant to the Pathwork Purchase Agreement, the Company acquired all intellectual property, know-how, data, equipment and materials formerly owned by Pathwork which relate to its FDA-cleared Tissue of Origin cancer test. Management evaluated the assets acquired from Seller and concluded the combined assets did not meet the definition of a business, primarily because the necessary processes were not acquired. Accordingly, the Company accounted for the transaction as a basket purchase of assets in which the purchase price was allocated to the individual assets acquired based upon relative fair value.

The Company acquired the assets for the following consideration: (i) an aggregate of 500,000 newly-issued registered shares of the Company’s common stock issued to two senior secured creditors of Pathwork which were designated by Seller in the Pathwork Purchase Agreement and (ii) a cash payment of $ 200,000 to Seller.

Based upon a valuation of the acquired Pathwork assets, the purchase price was allocated as follows: $ 257,000 to accounts receivable, $ 785,000 to laboratory equipment, and $ 138,000 to internally developed software and other intangible assets. The Company launched the Pathwork acquired Tissue of Origin test commercially as its ResponseDX: Tissue of OriginTM test in February 2014. Therefore, depreciation and amortization of these assets will begin during the first quarter of 2014 over their expected useful lives, which are approximately five years.

Expected future amortization of intangible assets over the next five years ending December 31 is as follows: $ 176,518 in 2014, $ 179,302 in 2015, $ 165,033 in 2016, $ 145,173 in 2017, $ 64,698 in 2018 and $ 3,499 thereafter.

Capital Leases

The Company leases certain equipment and related software that is recorded as capital leases. This equipment and software is included in property and equipment on the accompanying balance sheet as of December 31, 2013 as follows:

Equipment and software financed under capital leases	$	584,150

4. Loss Per Share

The Company calculates net loss per share in accordance with ASC 260, Earnings Per Share . Under the provisions of ASC 260, basic net loss per share is computed by dividing the net loss for the period by the weighted average number of shares of common stock outstanding for the period. Diluted net loss per share is computed by dividing the net loss by the weighted average number of shares of common stock and dilutive common stock equivalents then outstanding. Common stock equivalents consist of shares of common stock issuable upon the exercise of stock options.

The following table sets forth the computation for basic and diluted loss per share:

	Year Ended December 31,
	2012		2013
Numerator:
Net loss	$	(7,757,079)	$	(8,020,515)
Numerator for basic and diluted earnings per share	$	(7,757,079)	$	(8,020,515)

Denominator:
Denominator for basic and diluted earnings per share — weighted-average shares outstanding		26,742,345		33,481,439

Basic and diluted loss per share	$	(0.29)	$	(0.24)

Outstanding stock options to purchase 1,749,310 and 2,288,076 shares for the years ended December 31, 2012 and 2013, respectively, were excluded from the calculation of diluted loss per share as their effect would have been anti-dilutive .

5 . Commitments and Contingencies

Operating Leases

The Company leases 27,446 square feet of office and laboratory space in Los Angeles, California, under a non-cancelable operating lease that was amended and extended on February 3, 2014 and will expire on June 30, 2015 . The Company has the option to extend the lease to June 30, 2016. The Company also leased 1,460 square feet of space in Frederick, Maryland, where administrative functions were performed until July 31, 2012. The Company moved the administrative functions performed out of this office primarily to its Los Angeles facilities and closed the Maryland office on July 31, 2012. The lease for the Maryland office expired on January 31, 2013 .

Rent expense, which is classified in cost of revenue, general and administrative, and research and development expenses was $ 686,651 and $ 683,926 for the years ended December 31, 2012 and 2013, respectively.

Guarantees

The Company enters into indemnification provisions under its agreements with other counterparties in its ordinary course of business, typically with business partners, clients and landlords. Under these provisions, the Company generally indemnifies and holds harmless the indemnified party for losses suffered or incurred by the indemnified party as a result of the Company's activities. These indemnification provisions generally survive termination of the underlying agreement. The Company reviews its exposure under these agreements no less than annually, or more frequently when events require. The Company believes the estimated fair value of these agreements is minimal as, historically, no payments have been made by the Company under these indemnification obligations. Accordingly, the Company has no liabilities recorded for these agreements as of December 31, 2012 and December 31, 2013.

Legal Matters

The Company is, from time to time, involved in legal proceedings, regulatory actions, claims and litigation arising in the ordinary course of business. Reserves are established for specific liabilities in connection with legal actions when they can be deemed probable and estimable. These matters are not expected to have a material adverse effect upon the Company’s financial condition.

Employment Agreements

The Company has employment contracts with several individuals, which provide for annual base salaries and potential bonuses. These contracts contain certain change of control, termination and severance clauses that require the Company to make payments to certain of these employees if certain events occur as defined in their respective contracts.

7. Stock Option Plans

In March 2000, the Company adopted a Stock Option Plan (the “2000 Stock Plan”) as approved by its Board of Directors. Under the 2000 Stock Plan, the Company granted options to acquire up to 1,600,000 shares of common stock. In connection with the adoption of the 2006 Employee, Director and Consultant Stock Plan, as further discussed below, the Company is to grant no additional options under the 2000 Stock Plan. Under the 2000 Stock Plan, there were no options to purchase shares of the Company’s common stock that remained outstanding as of December 31, 2012. Prior to March 2007, the Company also granted options to purchase 16,000 shares of common stock to two consultants which were granted under separate agreements outside of the 2000 Stock Plan.

On October 26, 2006, the Board of Directors of the Company approved, and on May 1, 2007, reapproved the adoption of the 2006 Employee, Director and Consultant Stock Plan (the “2006 Stock Plan”). The stockholders approved the 2006 Stock Plan on June 1, 2007. The initial number of shares which may be issued from time to time pursuant to the 2006 Stock Plan was 2,160,000 shares of common stock. Also, the 2006 Stock Plan includes the number of shares subject to purchase under options issued under the 2000 Stock Plan, where the options expired on or after October 18, 2006, subject to a maximum of 210,000 additional options. In addition, on the first day of each fiscal year of the Company during the period beginning in fiscal year 2008 and ending on the second day of fiscal year 2017, the number of shares that may be issued from time to time pursuant to the 2006 Stock Plan is increased by the lesser of (i) 200,000 shares or equivalent, after determination of the effect of any stock split, stock dividend, combination or similar transactions as set forth in the 2006 Stock Plan, (ii) 5 % of the number of outstanding shares of common stock of the Company on such date or (iii) an amount determined by the Board of Directors of the Company. The initial number of shares available for issuance of 2,160,000 increased by 210,000 for options issued under the 2000 Stock Plan expiring after October 2006 and by 200,000 in each year from 2008 through 2013 , resulting in the total number of shares that may be issued as of January 1, 2013 to be 3,570,000 . As of December 31, 2013, there were 1,281,924 options available for grant under the 2006 Stock Plan.

Employee options vest according to the terms of the specific grant and expire 10 years from the date of grant. Non-employee option grants to date vest typically over a 2 to 3 year period. Under the 2006 Stock Plan, the Company had 2,288,076 options outstanding at a weighted average exercise price of $ 1.83 at December 31, 2013. There were 1,362,317 non-vested stock options with a weighted average grant date fair value of $ 1.02 outstanding at December 31, 2013. As of December 31, 2013, there was $ 1,130,494 of total unrecognized compensation cost related to non-vested share-based compensation arrangements granted under the 2006 Stock Plan. That cost is expected to be recognized over a weighted-average period of 3.0 years.

Except for the certain grants of restricted common stock and common stock options containing market conditions as described below, the Company estimated share-based compensation expense for the years ended December 31, 2012 and 2013 using the Black-Scholes model with the following weighted average assumptions:

	Year Ended December 31,
	2012		2013
Risk free interest rate	0.79-1.32	%	0.90-1.77	%
Expected dividend yield	—		—
Expected volatility	71.9-101.2	%	102.2-107.4	%
Expected term **(in years)	6.0-6.25		5.0-6.0
Forfeiture rate	7.0	%	7.0	%

** Expected term is calculated using SAB 107, Simplified Formula. Management has concluded that the use of the simplified method for calculating the expected term of its common stock option grants is appropriate given the lack of historical exercises and the standard terms of the employee option grants, including options are granted at-the-money, exercise is conditional only on performing service through the vesting dates, termination of service causes forfeiture of options, employees have a limited number of days to exercise options after termination of service, and options are non-transferable.

The exercise price of the stock options is $ 1.20 per share, the closing price of the Company’s common stock on the day prior to the date of grant. The expense recognized in connection with these grants was approximately $ 540,000 and $ 178,122 for the years ended December 31, 2012 and 2013, respectively, and is included in the above table.

7. Stock Option Plans - (continued)

Since the restricted shares of common stock grant vests upon attainment of a target price for the Company’s common stock and each tranche of the 300,000 share common stock option grant can vest sooner than the stated vesting dates based upon attainment of a target price for the Company’s common stock, these awards are deemed to include market conditions for purposes of determining the valuation and accounting for the awards. Accordingly, the fair value of the restricted shares of common stock grant and each tranche of the 300,000 share common stock option grant that Mr. Bologna received was determined using a Monte-Carlo simulation model to simulate the Company’s stock prices in the future that would trigger or not trigger the market conditions. For these awards containing market conditions, the compensation amount will be attributed over the service date unless vesting occurs sooner due to achieving the market condition.

The following table summarizes these awards to Mr. Bologna:

			Intrinsic
			Value as of					Remaining
			December 31,				Options	Contractual
Type	Grant Date	Number of Awards	2013		Exercise Price		Exercisable	Term
Restricted Shares of Common Stock	12/21/2011	270,000	$	313,200	$	—	—	8.0

Options	12/21/2011	300,000	$	—	$	1.20	300,000	8.0

During the first quarter of 2012, Mr. Bologna’s stock option award of 300,000 shares met the conditions for vesting in that the 30-day trailing average closing price of the Company’s common stock exceeded $1.80. The Company recognized expense of $ 129,000 for the vesting of this tranche of options for Mr. Bologna’s stock awards during the quarter ended March 31, 2012.

Deferred income taxes result from temporary differences between income tax and financial reporting computed at the effective income tax rate. The Company has established a valuation allowance against its deferred tax assets due to the uncertainty surrounding the realization of such assets. Management periodically evaluates the recoverability of the deferred tax assets. At such time it is determined that it is more likely than not that deferred tax assets are realizable, the valuation allowance will be reduced.

The Company files U.S. federal, U.S. state, and foreign tax returns. The Company’s major tax jurisdictions are U.S. federal and the State of California and are subject to tax examinations for the open years from 2003 through 2013 .

As of December 31, 2013, the Company had net operating loss carryforwards for federal and state income tax purposes of approximately $ 40 million and $ 35 million, respectively. If not utilized, the federal net operating loss and tax credit carryforwards expire beginning in 2021 . The state net operating loss carryforward expires beginning in 2014 . Section 382 of the Internal Revenue Code contains rules that limit the ability of a company that undergoes an ownership change, which is generally a change in ownership of more than 50.0 percent of its stock over a three-year period, to utilize its net operating loss carryforwards. The Company has had numerous transactions in its common stock, and these transactions may have resulted in a change in ownership that limits the utilization of net operating loss carryforwards. The Company has not evaluated the impact of Section 382, if any, on its ability to utilize its net operating loss carry forwards in future years.

March 2010 Private Placement

On March 5, 2010, the Company entered into a purchase agreement with certain affiliates of and funds managed by Lansdowne Partners Limited Partnership (“Lansdowne”), Greenway Capital Partners and Paragon Associates for the private placement of 3,005,349 newly-issued shares of the Company’s common stock at a per share price of $ 1.31 . The closing of the sale of the shares occurred on March 5, 2010. In connection with the acquisition of the shares, the purchasers were granted certain preemptive rights permitting them to maintain their percentage ownership interests in connection with future issuances of the Company’s capital stock, subject to various exceptions and limitations. Lansdowne participated in the private placement by electing to exercise the preemptive rights granted to it pursuant to the purchase agreement by and between the Company and Lansdowne, dated July 22, 2009. Net proceeds received from this financing were approximately $ 3,879,403 .

Under the registration rights agreements with the purchasers, the Company is obligated to use commercially reasonable efforts to (i) cause the registration statement described above to remain continuously effective and (ii) to maintain the listing of the Company’s common stock on NASDAQ or other exchanges, as defined, for a period that will terminate on the earlier of March 5, 2013 or the date on which the purchasers have sold all shares of common stock. The Company is also required to file with the SEC in a timely manner all reports and other documents required of the Company under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). In the event the Company fails to satisfy its obligations under the registration rights agreements, the Company would be in breach of said agreements, in which event, the purchases would be entitled to pursue all rights and remedies at law or equity including an injunction or other equitable relief. These registration rights agreements do not provide an explicitly stated or defined penalty due upon a breach. Because (i) the potential penalty for any breach of these registration rights agreement is not explicitly stated or defined, which prohibits the Company from applying the guidance of ASC 825-20-15, Registration Payment Arrangements and (ii) complying with all filing requirements under the Exchange Act as described above is not solely within the Company’s control, the Company is required to present the investment of approximately $ 3,879,403 in the Company’s common stock as common stock outside of stockholders’ equity in the accompanying consolidated balance sheet under ASC 480-10-S99-3, Classification and Measurement of Redeemable Securities .

On January 18, 2012, the Company removed the restrictions on 3,658,676 shares purchased by Lansdowne, of which 600,769 related to this offering, and reclassified the shares to common stock from common stock classified outside of equity (deficit). On March 5, 2013, the Company reclassified the remaining shares of common stock from this offering to common stock from common stock classified outside of equity (deficit). Therefore, as of December 31, 2012 and 2013, a total of $ 3,092,396 and $ 0 of the March 2010 private placement common stock was classified outside of stockholders’ equity (deficit), respectively.

February 2012 Private Placement

On February 2, 2012, the Company entered into purchase agreements with various investors (collectively, the “February Investors”) for the private placement of an aggregate of 5,257,267 newly-issued shares of the Company’s common stock (the “February Shares”) at a purchase price of $ 1.50 per share (the “February 2012 Private Placement”). Net cash proceeds raised in the February 2012 Private Placement were approximately $ 7,822,000 . The February Investors participating in the February 2012 Private Placement were various institutions and all the then serving officers and directors of the Company. The final closing of the February 2012 Private Placement (the “February Closing”) occurred on February 2, 2012.

In connection with the February 2012 Private Placement, the Company also entered into registration rights agreements, each dated February 2, 2012, with the February Investors pursuant to which the Company agreed to file, within 90 days of the February Closing, a registration statement with the SEC to register the February Shares for resale, which registration statement is required to become effective within 180 days following the February Closing. The Company also granted the February Investors certain “piggyback” registration rights, which are triggered if the Company proposes to file a registration statement for its own account or the account of one or more shareholders until the earlier of the sale of all of the February Shares or the February Shares becoming eligible for sale under Rule 144(b)(1) without restriction.

Under the registration rights agreements with the February Investors, the Company is obligated to use commercially reasonable efforts to (i) cause the registration statement described above to remain continuously effective and (ii) to maintain the listing of the Company’s common stock on NASDAQ or other exchanges, as defined, for a period that will terminate on the earlier of February 2, 2013, the date on which the February Investors have sold all covered registrable securities or the date on which there are no longer any covered registrable securities outstanding. The Company is also required to file with the SEC in a timely manner all reports and other documents required of the Company required of the Company under the Exchange Act. In the event the Company fails to satisfy its obligations under the registration rights agreements, the Company would be in breach of said agreements, in which event, the February Investors would be entitled to pursue all rights and remedies at law or equity including an injunction or other equitable relief. These registration rights agreements do not provide an explicitly stated or defined penalty due upon a breach. Because (i) the potential penalty for any breach of these registration rights agreement is not explicitly stated or defined, which prohibits the Company from applying the guidance of ASC 825-20-15, Registration Payment Arrangements and (ii) complying with all filing requirements under the Exchange Act as described above is not solely within the Company’s control, the Company was required to present the investment of approximately $ 7,885,900 in the Company’s common stock as common stock outside of stockholders’ equity in the accompanying consolidated balance sheet under ASC 480-10-S99-3, Classification and Measurement of Redeemable Securities .

The Company raised gross cash proceeds of $ 8,800,000 in the September 2012 Private Placement which closed on September 13, 2012 (the “Closing”).

Pursuant to the Purchase Agreement, for so long as the GSK Investor or its affiliates own at least 50 % of the September Shares it purchased pursuant to the Purchase Agreement, the GSK Investor has the right to designate one non-voting board observer (the "Board Observer"). The Board Observer, if appointed, has the right to attend all meetings of the Board of Directors of the Company and to receive all board meeting materials, subject to certain restrictions set forth in the Purchase Agreement. As of the date hereof, the GSK Investor has not exercised its right to designate the Board Observer.

In connection with the September 2012 Private Placement, the Company also entered into a registration rights agreement, dated September 13, 2012 (the “September Registration Rights Agreement”), with the September Investors pursuant to which the Company agreed to file, within 45 days of the Closing, a registration statement with the SEC to register the September Shares for resale, which registration statement is required to become effective within 180 days following the Closing. The Company also granted the September Investors certain “piggyback” registration rights, which are triggered if the Company proposes to file a registration statement for its own account or the account of one or more stockholders until the earlier of the sale of all of the September Shares or the September Shares becoming eligible for sale under Rule 144(b)(1) without restriction.

Under the September Registration Rights Agreement, the Company is obligated to use commercially reasonable efforts to cause a registration statement to become effective and to remain continuously effective and to maintain the listing of the covered common stock on NASDAQ or other exchanges, as defined, for a period that will terminate upon the earlier of (i) the date on which all Registrable Securities covered by such Registration Statement as amended from time to time, have been sold, (ii) the date on which there are no longer any Registrable Securities outstanding or (iii) three years from the date of filing of such Registration Statement (the “ Effectiveness Period ”) and advise each September Investor in writing when the Effectiveness Period has expired. “Registrable Securities” means (i) the September Shares and (ii) shares of capital stock or any other securities issued or issuable with respect to or in exchange for the September Shares; provided, that, a security shall cease to be a Registrable Security with respect to a September Investor upon (A) sale by such September Investor pursuant to a registration statement or Rule 144 under the 1933 Act, or (B) such security becoming eligible for sale by such September Investor without restriction pursuant to Rule 144(b)(1). In the event the Company fails to satisfy its obligations under the September Registration Rights Agreement, the Company would be in breach of such agreement, in which event, the September Investors would be entitled to pursue all rights and remedies at law or equity including an injunction or other equitable relief. The September Registration Rights Agreement does not provide an explicitly stated or defined penalty due upon a breach. Because the potential penalty for any breach of these registration rights agreement is not explicitly stated or defined, which prohibits the Company from applying the guidance of ASC 825-20-15, Registration Payment Arrangements , the Company was required to present the investment of approximately $ 8,800,000 in the Company’s common stock as common stock outside of stockholders’ equity in the accompanying consolidated balance sheet under ASC 480-10-S99-3, Classification and Measurement of Redeemable Securities .

11. Fair Value Measurements

ASC 820, Fair Value Measurements and Disclosures, defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements. ASC 820 provides guidance on how to measure fair value by providing a fair value hierarchy used to classify the source of the information. ASC 820 establishes a three-level valuation hierarchy of valuation techniques that is based on observable and unobservable inputs. Classification within the hierarchy is determined based on the lowest level of input that is significant to the fair value measurement. The first two inputs are considered observable and the last unobservable, that may be used to measure fair value and include the following:

Level 1 - Quoted prices in active markets for identical assets or liabilities.

Level 2 - Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

As of December 31, 2013, the Company held certain assets that are required to be measured at fair value on a recurring basis, including its cash and cash equivalents. The fair value of these assets was determined using the following inputs in accordance with ASC 820 at December 31, 2012 and 2013:
