	(b)		For their Services performed from and after the consummation of the Acquisition, the Active Sponsors as a group will be entitled to receive from the Companies (i) the Initial Period Management Fee, payable at the closing of the Acquisition and (ii) the Annual Management Fee payable annually on June 30 of each year commencing June 30, 2004 through June 30, 2013. The Annual Management Fee payable on each June 30 shall be shared among the Active Sponsors as of such June 30 in the percentage for each such Active Sponsor equal to the ownership interest in the common equity securities of Parent owned by such Active Sponsor and its affiliated designees on such June 30 divided by the aggregate ownership interests in the common equity securities of Parent owned by all such Active Sponsors and their affiliated designees on such June 30.
			In addition, each Active Sponsor shall be entitled to receive reimbursement of all out of pocket expenses paid or incurred (including expenses of any consultant) by such Active Sponsor in connection with its Services to the Companies. Such expenses shall be reimbursed to the Active Sponsor by the Companies promptly upon request by such Active Sponsor.

	(d)		Holdco shall be primarily responsible for the payment of the Closing Fees, the Initial Period Management Fee and the Annual Management Fees and expenses referred to herein, it being agreed that the Services will primarily benefit Holdco. However, in the event Holdco does not pay all or any portion of such Initial Period Management Fee or any Annual Management Fee or any such expenses, each of the other Companies shall be jointly and severally liable for the unpaid amount thereof and shall pay the same on demand by any Active Sponsor.
	(e)		In the event that the Acquisition is not consummated, the Sponsors shall calculate the total amount of out of pocket expenses paid or incurred (including expenses of any consultants) by all of the Sponsors related to the potential Acquisition (the “Dead Deal Costs”). The Sponsors and BNP shall each contribute to the payment of the expenses as set forth in Exhibit B. By separate letter, BNP has agreed to pay its share of such expenses as set forth in Exhibit B.

3. Future Corporate Transactions. The Companies agree that if any of the Companies determine, within ten years after the closing of the Acquisition, to acquire (regardless of the form of such transaction, and whether directly or through one or more affiliated entities) assets of a value of US$1 million or more (other than assets representing capital expenditures in the ordinary course of business) or any business (each a “Future Corporate Transaction”), each Designated Active Sponsor with respect to such Future Corporate Transaction is hereby retained by the Companies in connection with such Future Corporate Transaction, to provide services to the Companies of the same nature as the Services (to the extent required), and the Companies will pay to all such Designated Active Sponsors acting as such with respect to such Future Corporate Transaction, as a group, at the consummation of such Future Corporate Transaction, a fee in the amount of one percent (1.0%) of the Project Value thereof and, regardless of whether such Future Corporate Transaction is consummated, the Companies shall reimburse each such Designated Active Sponsor for all expenses paid or incurred by such Designated Active Sponsor in connection therewith. In addition, the Companies agree that if any of the Companies determine, within ten years after the closing of Acquisition, to offer securities for sale to the public or in private placement or otherwise raise any debt or equity financing other than the “Bridge Refinancing” as defined in the Purchase Agreement for the Acquisition (each a “Future Securities Transaction”), each Designated Active Sponsor with respect to such Future Securities Transaction is hereby retained by the Companies, in connection with such Future Securities Transaction, to provide consulting services to the Companies in connection therewith, and the Companies will pay to all such

		If more than one Designated Active Sponsor is retained with respect to a Future Corporate Transaction or a Future Securities Transaction, the fee payable as set forth above shall be shared between or among them in such proportions as they shall agree or, in the absence of such agreement, each such Designated Active Sponsor shall be entitled to that percentage of the fee equal to the number of shares of common equity securities of Parent owned by such Designated Active Sponsor and its affiliated designees divided by the number of shares of common equity securities of Parent owned by all such Designated Active Sponsors and their affiliated designees.
		For purposes of this Agreement, (a) the term “Designated Active Sponsor” shall mean an Active Sponsor that has been designated by the Board of Directors of Parent to act as a Designated Active Sponsor for a particular transaction and identified by written notice to all Active Sponsors and approved by the then Active Sponsors that, together with their affiliated designees, hold at least 662/3% of the common equity securities of Parent then owned by all of the Active Sponsors and their affiliated designees (the “Requisite Approval”); provided that if the Board of Directors of Parent fails to designate at least one Designated Active Sponsor approved by the Requisite Approval for any transaction, the Active Sponsors shall designate from among themselves by the Requisite Approval one or more Active Sponsors to act as Designated Active Sponsor(s) with respect to such transaction; and (b) the term “Project Value” shall mean the aggregate consideration paid by any Company to a third party to consummate an acquisition plus the aggregate amount of all liabilities assumed by the acquiring party in connection with an acquisition.
		Holdco shall be primarily responsible for the payment of fees and expenses referred to in this Section 3, it being agreed that the services of the Designated Active Sponsor(s) under this Section 3 will primarily benefit Holdco. However, in the event Holdco does not pay all or any portion of any such fee or expenses, each of the other Companies shall be jointly and severally liable for the unpaid amount thereof and shall pay the same on demand by the Designated Active Sponsor(s).
4.		Indemnification. The Companies, jointly and severally, agree to indemnify and hold harmless each Sponsor, its consultants, each of their respective controlling persons and each director, officer, employee, principal, consultant, affiliate and agent thereof (each an “Indemnified Person”) from and against any and all losses,

Letter Agreement

November 21, 2003

claims, damages and liabilities joint and several, to which any Indemnified Person may become subject relating to or arising out of, or in connection with, any advice or services provided under this Agreement or the transactions contemplated by this Agreement, the Acquisition (including, without limitation, the use of proceeds from the sale of securities and the financing of the Acquisition) or any related transaction (including without limitation, that certain commitment letter among Sterling, BNP and BNP Paribas Securities Corp. dated October 31, 2003 which letter relates to the financing of the Acquisition, and the transactions contemplated thereby), and to reimburse each Indemnified Person, promptly upon demand, for expenses (including reasonable counsel fees and expenses) as they are incurred in connection with the investigation of, giving testimony or furnishing documents for, preparation for or defense of any pending or threatened loss, claim, damage or liability, or any litigation, proceeding or other action in respect thereof (collectively, “Actions”), including any amount paid in settlement of any litigation, proceeding or other action (commenced or threatened), to which Parent shall have consented in writing (such consent not to be unreasonably withheld), whether or not any Indemnified Person is a party and whether or not liability resulted therefrom; provided, however, that the indemnity contained in this Agreement will not apply to any Indemnified Person with respect to losses, claims, damages, liabilities or related expenses that are found in a final judgment by a court of competent jurisdiction (not subject to further appeal) to have resulted from the willful misconduct of such Indemnified Person. In addition, the Companies will not, without prior written consent of such Indemnified Person, settle, compromise or consent to the entry of any judgment in or otherwise seek to terminate any pending or threatened Action in respect of which indemnification or contribution may be sought hereunder (whether or not any Indemnified Person is a party thereto) unless such settlement, compromise, consent, or termination, includes unconditional release of such Indemnified Person from all liabilities arising out of such Action.

Promptly after receipt by an Indemnified Person of written notice with respect to the commencement of any investigation, claim or other Action with respect to which such Indemnified Person may seek indemnification hereunder, such Indemnified Person shall notify Parent in writing at the address set forth on the first page hereof of such Action; but the omission so to notify Parent shall not relieve the Companies from any liability that the Companies may have hereunder to such Indemnified Person to the extent that such omission does not materially prejudice or materially adversely affect the Companies. The Indemnified Persons shall be entitled to retain separate counsel of their own choice; provided that the Companies shall not be responsible for the fees and expenses of more than one firm of attorneys (and local counsel, if appropriate) for all of the Indemnified Persons in any single Action, unless the Indemnified Persons shall have been advised that there may be one or more legal defenses available to any of them that may be different from or additional to those available to the others, in which event

Letter Agreement

November 21, 2003

each such Indemnified Person shall be entitled to separate counsel at the expense of the Companies.

If indemnification is found in a final judgment by a court of competent jurisdiction (not subject to further appeal) for reason of public policy not to be available, the Companies and the Sponsors agree to contribute to the losses, claims, damages, liabilities or expenses (or actions in respect thereof) for which such indemnification is held unavailable in such proportion as is appropriate to reflect the relative benefits to and fault the Companies, on the one hand, and the Sponsors, on the other hand, in connection with the matter giving rise to such losses, claims, damages, liabilities or expenses (or actions in respect thereof). Notwithstanding the foregoing, no Sponsor shall be obligated to contribute any amount hereunder that exceeds the fees and expenses received by such Sponsor hereunder. No person found liable for a fraudulent misrepresentation (within the meaning of Section 11 (f) of the Securities Act of 1933 as amended) shall be entitled to contribution from any person who is not found liable for such fraudulent misrepresentation.

The Companies also agree, jointly and severally, that no Indemnified Person shall have any liability (whether direct or indirect, in contract or tort or otherwise) to the Companies for or in connection with advice or services rendered or to be rendered by any Indemnified Person pursuant to this Agreement, the Acquisition, the financing thereof, the transactions contemplated thereby or any Indemnified Person’s actions or inactions in connection with any such advice, services or transactions except for liabilities that are determined by a judgment of a court of competent jurisdiction (not subject to further appeal) to have resulted from such Indemnified Person’s willful misconduct in connection with any such advice, actions, inactions or services.

If any term, provision, covenant or restriction contained in this Section is held by a court of competent jurisdiction or other authority to be invalid, void, unenforceable or against public policy, the remainder of the terms, provisions, covenants and restriction contained in the Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated.

The provisions contained in this Section 4 shall remain in full force and effect (i) whether or not any of the transactions contemplated hereby are consummated, (ii) regardless of the termination or completion of any Indemnified Person’s services hereunder, (iii) notwithstanding the termination of this Agreement and (iv) notwithstanding any investigation made by or on behalf of the Sponsors or any Indemnified Person.

     THE INDEMNIFICATION OF AND CONTRIBUTION RIGHTS OF AN INDEMNIFIED PERSON UNDER THIS SECTION 4 EXPRESSLY SHALL APPLY REGARDLESS OF WHETHER THE DAMAGES TO BE INDEMNIFIED AGAINST OR CONTRIBUTED TO ARISE, OR ARE ALLEGED TO ARISE, FROM SUCH INDEMNIFIED PERSON’S OWN NEGLIGENCE

Letter Agreement

(WHETHER SOLE, JOINT OR CONCURRENT), GROSS NEGLIGENCE, NEGLIGENCE PER SE AND/OR STRICT LIABILITY; PROVIDED THAT SUCH INDEMNIFICATION AND CONTRIBUTION RIGHTS SHALL NOT APPLY TO DAMAGES THAT ARE FOUND IN A FINAL JUDGMENT BY A COURT OF COMPETENT JURISDICTION (NOT SUBJECT TO FURTHER APPEAL) TO HAVE RESULTED FROM THE WILLFUL MISCONDUCT OF SUCH INDEMNIFIED PERSON.

5.		Termination. Each Active Sponsor may terminate its Services hereunder at any time and thereupon shall no longer be deemed to be an “Active Sponsor” hereunder. A Sponsor’s Services shall automatically terminate and such Sponsor shall no longer be deemed to be an “Active Sponsor” hereunder on the date such Sponsor and its affiliated designees cease to have any equity ownership in Parent. Parent may terminate an Active Sponsor’s Services under this Agreement only upon the terms set forth in the following paragraph.
		If the Parent intends to terminate an Active Sponsor’s Services hereunder, it shall first deliver to all Active Sponsors a written notice of intention to terminate such Active Sponsor’s Services (“Notice of Termination”). Parent may not deliver a Notice of Termination with respect to the termination of an Active Sponsor’s Services unless such Active Sponsor has materially breached a material obligation of such Active Sponsor under this Agreement. The Notice of Termination shall contain (i) a notice that Parent intends to terminate such Active Sponsor’s Services, (ii) a detailed description of the material breach of a material obligation alleged to have been committed by such Active Sponsor and (iii) a notice that said termination of Services shall be effective thirty days after it is received by such Active Sponsor unless within said thirty days after it is received by such Active Sponsor, (A) in the case of a material breach that can reasonably be remedied within such period, such Active Sponsor remedies the material breach, or (B) in the case of a material breach that cannot reasonably be remedied within such period, such Active Sponsor has instituted good faith measures to remedy such material breach. If such Active Sponsor remedies such material breach (in the case of clause (A) of the immediately preceding sentence) or institutes such good faith measures to remedy such material breach (in the case of clause (B) of the immediately preceding sentence), such Notice of Termination shall be deemed to be revoked, such material breach shall be deemed to be remedied and Parent shall not have the right to terminate such Active Sponsor’s Services due to such material breach.
6.		Governing Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of Texas, without giving effect to choice of law doctrines requiring the application of laws of any other jurisdiction.
7.		Limited Liability. Notwithstanding any provision hereof, none of the obligations of any Sponsor or any of their respective affiliates that is an entity under this Agreement shall be an obligation of any officer, director, member, limited partner or general partner of any of the foregoing entities. Any liability or obligation of
