INTRODUCTORY STATEMENT

This Tender Offer Statement on this combined Schedule TO and Schedule 13E-3 under cover of Schedule TO (this “ Schedule TO ”) is being filed by Pampa and relates to the offer by Pampa to purchase any and all outstanding PESA Shares held by U.S. Persons (as defined herein) (the “ U.S. Cash Tender Offer ”). 

The U.S. Cash Tender Offer is being made on the terms and conditions set forth in the prospectus dated August  9 , 2016 (the “ Prospectus ”) attached hereto as Exhibit (a)(4)(i) and incorporated herein by reference, and in the related documents. The Prospectus is also being filed by Pampa in connection with an offer to exchange outstanding PESA Shares held by U.S. Persons and outstanding PESA ADSs for Pampa Common Shares, par value Ps.1.00 per share, and American Depositary Shares, each representing 25 Pampa Shares, under the terms and conditions set forth therein (the “ U.S. Exchange Offer ” and, together with the U.S. Cash Tender Offer, the “ U.S. Offers ”). The U.S. Offers are being made in conjunction with an offer by Pampa in Argentina for all outstanding PESA Shares (but not PESA ADSs, unless holders of PESA ADSs first convert their PESA ADSs into PESA Shares, which requires holders to surrender their PESA ADSs to JPMorgan Chase Bank N.A., as depositary for the PESA ADSs) (the “ Argentine Offer ,” and together with the U.S. Offers, the “ Offers ”). The Offer Cash Consideration (as defined in the Prospectus) offered in the Argentine Offer is the same as the Offer Cash Consideration offered in the U.S. Cash Tender Offer, payable in each case in Argentine pesos in Argentina. Pampa does not intend to change the Offer Cash Consideration and, while the Offers are open, will not purchase or make any arrangements to purchase PESA Securities, other than pursuant to the Offers. This Schedule TO is intended solely for holders of PESA Shares that are U.S. Persons. The information set forth in the Prospectus is incorporated herein by reference with respect to Items 1 through 11 of this Schedule TO. This Schedule TO is being filed on behalf of Pampa.

As used herein, a “ U.S. Person ” means: (1) any individual resident in the United States; (2) any partnership or corporation organized or incorporated in the United States; (3) any estate of which any executor or administrator is a U.S. Person; (4) any trust of which the trustee is a U.S. Person; (5) any agency or branch of a foreign entity located in the United States; (6) any non-discretionary account or similar account (other than an estate or trust) held by a dealer or other fiduciary for the benefit or account of a U.S. Person; (7) any discretionary account or similar account (other than an estate or trust) held by a dealer or other fiduciary organized, incorporated or (if an individual) resident in the United States; and (8) any partnership or corporation if (A) organized or incorporated under the laws of any foreign jurisdiction and (B) formed by a U.S. Person for the purpose of investing in securities not registered under the U.S. Securities Act of 1933, as amended (the “ Securities Act ”), unless it is organized or incorporated, and owned by accredited investors (as defined in Rule 501(a) under the Securities Act); excluding, in each case, persons deemed not to be “U.S. persons” pursuant to Rule 902(k)(2) of Regulation S under the Securities Act.
