CES may not Transfer any portion of its Securities unless otherwise permitted by this Article IV. 4.2 TRANSFERS SUBJECT TO COMPLIANCE WITH SECURITIES ACT. CES acknowledges that the Securities have not been registered under the Securities Act and agrees that no sale, transfer, assignment, hypothecation or other disposition of the Securities shall be made in the absence of (a) a current registration statement under the Securities Act as to the Securities and the registration or qualification of the Securities under any applicable state securities laws that is then in effect or (b) an opinion of counsel reasonably satisfactory to the Company to the effect that such registration or qualification is not required PROVIDED, HOWEVER, that an opinion of counsel shall not be required in connection with a Transfer by CES of the Securities pursuant to Rule 144(k) of the Securities Act. 4.3 RESTRICTIVE LEGENDS. Each certificate representing Securities held by CES, and each certificate representing Securities issued to any subsequent transferee, shall be stamped or otherwise imprinted with a legend in substantially the following form: THIS SECURITY IS SUBJECT TO RESTRICTIONS ON TRANSFER AND OTHER TERMS AND CONDITIONS SET FORTH IN THE SUBSCRIPTION AGREEMENT DATED AS OF JULY 31, 2000, A COPY OF WHICH MAY BE OBTAINED FROM THE COMPANY AT ITS PRINCIPAL EXECUTIVE OFFICES. 8 THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED ("SECURITIES ACT"), OR ANY STATE SECURITIES LAWS. SUCH SECURITIES MAY NOT BE OFFERED FOR SALE, SOLD, PLEDGED, TRANSFERRED, OR OTHERWISE DISPOSED OF IN THE ABSENCE OF (A) A CURRENT REGISTRATION STATEMENT UNDER THE SECURITIES ACT AS TO THE SECURITIES UNDER ANY APPLICABLE STATE SECURITIES LAWS THAT IS THEN IN EFFECT OR (B) AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE COMPANY TO THE EFFECT THAT SUCH REGISTRATION OR QUALIFICATION IS NOT REQUIRED. 4.4 LOCK-UP AGREEMENT. In connection with any Initial Public Offering of Common Stock, CES agrees to enter into an agreement on such terms as may be reasonably requested by the underwriters for the public offering not to directly or indirectly, sell, transfer or otherwise dispose of or transfer the economic benefits and burdens of, any of the Securities for a period of time following such Initial Public Offering as such underwriter may reasonably request but not to exceed 180 days, PROVIDED, HOWEVER, that the terms of such agreement are no more onerous or restrictive than the least restrictive restrictions imposed on holders of at least one-half of one percent (0.5%) of the fully diluted shares of Common Stock at the time of the Initial Public Offering and any officers or directors of the Company holding Common Stock. 4.5 CO-SALE PROVISIONS. EES agrees that until an Initial Public Offering, CES will be entitled to such rights as are afforded by EES or an Affiliate of EES (including, for purposes of this Section only, Cortez Energy Services, LLC) to the third party investors who invested cash in the Company pursuant to the Contribution Agreement (the "Investors") under the Stockholders Agreement dated as of January 6, 2000, among the Company and certain other parties, as such agreement is amended from time to time, to include any Securities issued hereunder in any Transfer of Common Stock or securities convertible into or exercisable for Common Stock ("Common Stock Equivalents") by EES or its Affiliates (including, for purposes of this Section only, Cortez Energy Services, LLC) to other parties. If the Investors are permitted to include shares of Common Stock and Common Stock Equivalents in connection with such a Transfer, then CES shall be entitled to include up to that number of Securities equal to (i) the number of Securities held by CES multiplied by (ii) a fraction the numerator of which is the number of shares of Common Stock and Common Stock Equivalents the Investors are entitled to sell in connection with such sale and the denominator of which is the number of shares of Common Stock and Common Stock Equivalents calculated on a fully-diluted basis then held by the Investors. The terms of such Transfer shall be no less favorable than the terms of the Transfer by EES, any Affiliate of EES or the Investors. CES shall not be required to make any representations or warranties in connection with such Transfer other than representations and warranties as to (i) CES's ownership of the Securities to be Transferred free and clear of all liens, claims and encumbrances, (ii) CES's power and authority to effect such Transfer and (iii) such matters pertaining to compliance with securities laws as the transferee may reasonably require. The closing of such purchase by the transferee shall be on the same date that the transferee acquires shares from EES, or its Affiliate, or the Investors that are selling; PROVIDED that CES is 9 given 20 days advance notice of such closing. 4.6 REGISTRATION RIGHTS. (a) The Company agrees that after the effectiveness of an Initial Public Offering (or such later date as applicable in accordance with Section 4.4 hereof), CES will be entitled to piggyback registration rights to include any shares of Common Stock issued hereunder (used herein, the "Piggyback Securities") in any registration statement filed by the Company with the Securities and Exchange Commission to register for sale shares of Common Stock for cash in an underwritten offering under the Securities Act (other than a registration statement on Form S-4 or Form S-8 or any successor forms thereto or other than in connection with an exchange offer or offering solely to the Company's existing security holders). Each time the Company proposes to so file a registration statement with respect to which CES has the right to request inclusion of Piggyback Securities, the Company shall promptly give written notice of such proposed filing to CES and, upon the written request by CES which shall be given to the Company within 10 days after delivery by the Company of the notice of intent to file a registration statement, CES may include in such registration Piggyback Securities (which request by CES shall specify the number of Piggyback Securities proposed to be included in such registration). The Company shall use commercially reasonable efforts to cause all such shares of Piggyback Securities that CES has requested to be included in such registration on the same terms and conditions as the Common Stock otherwise being sold in such registration; PROVIDED, HOWEVER, that if the managing underwriter or underwriter advises the Company to reduce the number of shares of Common Stock to be sold and the Company has the right to so reduce the number of shares included therein by the Investors pursuant to the Stockholders Agreement, then the number of Piggyback Securities included by CES shall be reduced at the same time the number of shares included by the Investors are reduced on a pro rata basis based on the number of Securities held by CES and the number of shares of Common Stock calculated on a fully-diluted basis then held by the Investors that requested the inclusion of shares in such registration. Notwithstanding the foregoing, CES shall not have any piggyback registration rights with respect to Securities that it may sell pursuant to Rule 144(k) (or any successor provision) promulgated under the Securities Act or (if the provisions would not result in any material limitation on CES's ability to sell) otherwise pursuant to Rule 144 (or any successor provision) promulgated under the Securities Act. The Company may suspend, terminate or withdraw a piggyback registration at any time in its sole discretion. (b) The Company shall pay the following registration expenses (the "Registration Expenses"): (i) all registration and filing fees (including, without limitation, with respect to filings to be made with the National Association of Securities Dealers, Inc.), (ii) fees and expenses of compliance with securities or blue sky laws (including reasonable fees and disbursements of counsel in connection with blue sky qualifications of the Piggyback Securities), (iii) printing expenses, (iv) internal expenses (including, without limitation, all salaries and expenses of its officers and employees performing legal or accounting duties), (v) the fees and expenses incurred in connection with the listing on an exchange of the Piggyback Securities if the Company shall choose to list such Piggyback Securities, (vi) reasonable fees and disbursements of counsel for the Company and customary fees and expenses for independent certified public accountants retained by the Company, 10 (vii) the reasonable fees and expenses of any special experts retained by the Company in connection with such registration, and (viii) fees and expenses of any "qualified independent underwriter" or other independent appraiser participating in any offering pursuant to Section 3 of Schedule E to the By-laws of the National Association of Securities Dealers, Inc. The Company shall not have any obligation to pay any underwriting fees, discounts, or commissions attributable to the sale of Piggyback Securities or, except as provided by clause (ii) or (viii) above, any out-of-pocket expenses of CES (or the agents who manage its accounts) or the fees and disbursements of any underwriter.

If, in the reasonable judgment of counsel to the Company, a proposed Transfer by CES would constitute a violation of this Agreement, then the Company may refuse to register such proposed Transfer of Securities on the stock transfer records of the Company and give related instructions to its stock transfer agent, if any, to stop the registration of such proposed Transfer of Securities to the extent reasonably necessary to avoid such violation. 5.4 NOTICES.
