In supporting the transaction, ISS RiskMetrics stated: �Based on a review of the terms of the transaction and the factors described above, in particular, the strategic rationale and the enhanced governance provisions, the merger agreement warrants shareholder support.

We also support the board�s active engagement in the process, as well as the use of an auction process to help maximize shareholder value.� Thomas P. Richards, Chairman, President and CEO of Grey Wolf, said, �We are pleased that both ISS and Proxy Governance agree that this transaction is in the best interests of our shareholders. Grey Wolf shareholders will receive both immediate value through the cash component of the consideration and will also have the opportunity to participate in the upside as securityholders in the combined company.
