Attention:            James P. Ulm, II
Senior Vice President and Chief Financial Officer

Ladies and Gentlemen:

We are pleased to confirm the arrangements under which Goldman Sachs Credit Partners L.P. (“GSCP” or the “Administrative Agent”) is exclusively authorized by Pogo Producing Company (the “Company”) to act as sole lead arranger, sole bookrunner, sole syndication agent and administrative agent in connection with the bridge loans described herein, and, together with any other lenders set forth on Schedule I hereto and any entities that become lenders in accordance with the syndication arrangements set forth below (collectively with GSCP, the “Lenders”), commits to provide the bridge loans described herein, in each case, on the terms and subject to the conditions set forth in this letter, the attached Annex A and Annex B (collectively, the “Commitment Letter”) and the Fee Letter (as defined below).

You have informed GSCP that the Company, a Delaware corporation, intends to sign an agreement (the “Acquisition

Agreement”) to acquire by merger (the “Acquisition”) all of the capital stock of a private company code-named Lambada (the “Seller”), as specified in the Acquisition Agreement (the “Acquired Business”). You have also informed us that the total purchase price for the Acquisition (including the refinancing of certain debt of the Acquired Business, but excluding the payment of fees, commissions and expenses in connection with the Acquisition) will be approximately $750.0 million and that the Acquisition will be financed with (i) the issuance by the Company of up to $500.0 million in aggregate principal amount of debt, equity or equity-linked securities (the “Permanent Securities”) or, in the event the Permanent Securities are not issued at the time the Acquisition is consummated, borrowings by the Company of up to $500.0 million under senior unsecured increasing rate bridge loans (the “Bridge Loans”) having the terms of set forth in Annex B and (ii) borrowings by the Company of up to $375.0 million under its existing credit agreement, dated as of December 16, 2004, as amended on August 31, 2005, among the Company, as borrower, certain commercial lending institutions, as the lenders, and Bank of Montreal, acting through its Chicago, Illinois branch, as the administrative agent (the “Credit Facility”). On the Closing Date (as defined below), neither the Company nor any of its subsidiaries will have any debt for borrowed money or equity outstanding, except for (i) debt and equity outstanding as of the date hereof, (ii) borrowings not to exceed an amount to be agreed upon under the Credit Facility, (iii) equity issued to management and employees of the Company pursuant to existing equity compensation plans or (iv) as described in this paragraph. In addition, the Acquired Business will have permanently repaid all of its indebtedness on or before the Closing Date.

1.  Commitment.    GSCP is pleased to confirm its commitment to act as sole lead arranger and sole bookrunner to provide the Company with structuring advice in connection with the Bridge Loans, to act as sole syndication agent to provide the Company with syndication advice in connection with the Bridge Loans and to act as administrative agent for the Bridge Loans. Each of the Lenders is pleased to confirm its commitment (each, a “Commitment” and, collectively, the “Commitments”), severally and not jointly, to provide the Bridge Loans having the terms set forth on Annex B, in each case, on the terms and subject to the conditions contained in this Commitment Letter and the Fee Letter. The Commitment of each Lender individually is set forth opposite its name on Schedule 1 hereto; all of the Commitments together equal up to $500.0 million. The Company agrees that the Lenders will have the exclusive right during the term of this Commitment Letter to provide any bridge or interim financing utilized by the Company or any of its affiliates to finance any portion of the Acquisition.

Each Lender’s commitment is subject, in its discretion, to the conditions set forth in Annex B hereto and there not having occurred any material adverse change, or any development involving a prospective material adverse change, in or affecting the general affairs, management, financial position, stockholders’ equity or results of operations of the Company or the Acquired Business and their respective subsidiaries since December 31, 2005 (the date of the most recent audited financial statements for the Company and the Acquired Business, respectively, furnished by the Company to GSCP). Each Lender’s commitment is also subject, in its discretion, to the satisfactory negotiation, execution and delivery of appropriate definitive documentation relating to the Bridge Loans, including, without limitation, a bridge loan agreement (the “Bridge Loan Agreement”), to be based upon and substantially consistent with the terms set forth in this Commitment Letter. Our commitment is also conditioned upon and made subject to our not becoming aware after the date hereof of any new or inconsistent information or other matter not previously disclosed to us relating to the Company, the Acquired Business or the Acquisition or the transactions contemplated by this Commitment Letter, which GSCP, in its reasonable judgment, deems material and adverse relative to the information or other matters disclosed to us prior to the date hereof

2.  Fees and Expenses.    The fees for these services are set forth in a separate letter (the “Fee Letter”), dated as of the date hereof, entered into by the Lenders and the Company. In addition, pursuant to an engagement letter (the “Engagement Letter”), dated as of the date hereof, between the Company and Goldman, Sachs & Co. (“Goldman Sachs”), the Company has, among other things, offered Goldman Sachs the right to act (or to have one of its affiliates act) as the sole placement agent, sole purchaser or sole underwriter in connection with the sale of the Permanent Securities.

3.  Syndication.    GSCP intends and reserves the right to syndicate the Commitments and/or the Bridge Loans to other Lenders, commencing on the earlier of 30 days after the Closing Date and June 30, 2006 (or at any time during which the Company is not diligently pursuing the issuance of Permanent Securities or cooperating with GSCP in accordance with Section 4). GSCP will select the Lenders after consultation with the Company. GSCP will lead the syndication, including determining the timing of all offers to potential Lenders and the acceptance of Commitments, any title of agent or similar designations or roles awarded to Lenders, the amounts offered and the compensation provided to each Lender from the amounts to be paid to GSCP pursuant to the terms of this Commitment Letter and the Fee Letter. GSCP will determine the final Commitment allocations and will notify the Company of such determinations. The Company agrees to use all commercially reasonable efforts to ensure that

GSCP’s syndication efforts benefit from the existing lending relationships of the Company. To facilitate an orderly and successful syndication of the Bridge Loans, you agree that, until the later of the termination of the syndication as determined by GSCP and 120 days following the date of initial funding under the Bridge Loans (the “Closing Date”), the Company will not, and will use commercially reasonable efforts to cause the Acquired Business to agree that it will not, syndicate or issue, attempt to syndicate or issue, announce or authorize the announcement of the syndication or issuance of, or engage in discussions concerning the syndication or issuance of, any debt facility or debt or preferred equity security of the Company or any of its affiliates (other than the Bridge Loans, any Permanent Securities and other indebtedness contemplated hereby), including any renewals or refinancings of any existing debt facility or debt or preferred equity security, without the prior written consent of GSCP.

4. Cooperation.    The Company agrees to cooperate with GSCP, and to cause the Acquired Business to cooperate with GSCP, in each case commencing promptly after the Closing Date, in connection with (i) the preparation of an information package regarding the business, operations, financial projections and prospects of the Company and the Acquired Business, including, without limitation, the delivery of all information relating to the transactions contemplated hereunder prepared by or on behalf of the Company or the Acquired Business deemed reasonably necessary by GSCP to complete the syndication of the Commitments and/or the Bridge Loans (including, without limitation, obtaining and maintaining a credit rating by Moody’s Investor Services, Inc. (“Moody’s”), and Standard & Poor’s Ratings Group, a division of The McGraw Hill Corporation (“S&P”)) and (ii) the presentation of an information package acceptable in format and content to GSCP in meetings and other communications with prospective Lenders in connection with the syndication of the Commitments and/or the Bridge Loans (including, without limitation, direct contact between senior management and representatives of the Company with prospective Lenders and participation of such persons in meetings). The Company will be solely responsible for the contents of any such information package and presentation and acknowledge that GSCP will be using and relying upon the information contained in such information package and presentation without independent verification thereof. The Company agrees that information regarding the Bridge Loans and information provided by the Company, the Acquired Business or their respective representatives to GSCP in connection with the Bridge Loans (including, without limitation, draft and execution versions of the Loan Documents, publicly filed financial statements, and draft or final offering materials relating to contemporaneous or prior securities issuances by the Company or the Acquired Business) may be disseminated to potential Lenders and other persons through one or more internet sites (including an IntraLinks workspace) created for purposes of syndicating the Bridge Loans or otherwise, in accordance with GSCP’s standard syndication practices (including hard copy and via electronic transmissions). Without limiting the foregoing, the Company authorizes the use of its logos in connection with any such dissemination,

At the request of GSCP, the Company agrees to prepare a version of the information package and presentation that does not contain material non-public information concerning the Company or the Acquired Business, their respective affiliates or their securities. In addition, the Company agrees that unless specifically labeled “Private—Contains Non-Public Information,” no information, documentation or other data disseminated to prospective Lenders in connection with the syndication of the Bridge Loans, whether through an internet site (including, without limitation, an IntraLinks workspace), electronically, in presentations at meetings or otherwise, will contain any material non-public information concerning the Company or the Acquired Business, their respective affiliates or their securities.

The Company represents and covenants that (i) all information (other than forward-looking statements and data, including projections) provided directly or indirectly by the Company to GSCP or the Lenders in connection with the transactions contemplated hereunder is and will be, when taken as a whole, complete and correct in all material respects and does not and will not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements contained therein, in light of the circumstances in which they were made, not misleading and (ii) the projections that have been or will be made available to GSCP or the Lenders by the Acquired Business or the Company have been and will be prepared in good faith based upon assumptions that are believed by the preparer thereof to be reasonable at the time made. You agree that if at any time prior to the Closing Date, any of the representations in the preceding sentence would be incorrect in any material respect if the information and projections were being furnished, and such representations were being made, at such time, then you will promptly supplement, or cause to be supplemented, the information and projections so that such representations will be correct in all material respects under those circumstances.

In addition, GSCP may employ the services of its affiliates in providing certain services hereunder and may exchange with such affiliates information concerning the Company, the Acquired Business and other companies that may be the subject of this arrangement, and such affiliates shall be entitled to the benefits afforded to GSCP hereunder.

The Commitments hereunder will terminate upon the first to occur of (i) the consummation of the Acquisition, (ii) the abandonment or termination of the Acquisition Agreement, (iii) a material breach by the Company under this Commitment Letter, the Fee Letter or the Engagement Letter and (iv) June 30, 2006, unless the closing of the Bridge Loans, on the terms and subject to the conditions contained herein, shall have been consummated prior to such date.

However, any information relating to the tax treatment or tax structure shall remain subject to the confidentiality provisions hereof (and the foregoing sentence shall not apply) to the extent reasonably necessary to enable the

Delivery of an executed counterpart of a signature page of this Commitment Letter by facsimile transmission will be effective as delivery of a manually executed counterpart hereof.

SCHEDULE 1

(in millions)

Annex A
