(iii)          VCSC shall pay the Termination Option Fee as provided in Section 2.2.

(f)            Transition Assistance.  (i)  VCSC shall provide assistance to the Partnership Parties as reasonably necessary or desirable in connection with the transfer of Human Resources Compensation, Payroll, Benefits and Employment services to the Partnership Parties as a result of the exercise of the VCSC Termination Option, a cancellation of services by the Partnership Parties pursuant to Section 2.1(d) hereof, or the expiration of this Agreement, and such assistance shall be within the Administrative Services provided hereunder (i.e., at no additional cost other than Direct Charges (as defined below in Section 2.2(c)).

3

provide reasonable cooperation and assistance in transferring the third party contracts associated with the telecommunications circuits and the cell phones, pagers, Blackberries and other personal communications devices as of the applicable Telecommunications Services Termination Date.

(ii)           If VCSC exercises the VCSC Termination Option to be effective as of the Optional Termination Dates specified on Schedule A and the Partnership Parties nonetheless request in writing the provision of one or more of the Human Resources Compensation, Payroll, Benefits and Employment Services beyond the applicable Optional Termination Date, then the VCSC Parties shall continue to provide such Human Resources Service until receipt of further written notice from any of the Partnership Parties that they wish to terminate the provision of such Service: (1) subject to increased fees pursuant to Section 2.2 below, and (2) in no event shall any VCSC Party be obligated to provide any of the Human Resources Services beyond December 31, 2008.

Section 2.2            Fees for Services.

(a)           Administrative Services Fees (i) For Administrative Services rendered from the Effective Date of this Agreement through December 31, 2006, the Operating Partnership shall pay to VCSC $11,846.

(ii)           Beginning January 1, 2007, the Operating Partnership shall pay to VCSC a monthly fee (the “Administrative Services Fee”) for each of the Administrative Services as specified on Schedule A (subject to adjustment as set forth in (iii) immediately below) for each month up to and including the month in which the Administrative Service Termination Date for each such Service occurs.  The Partnership Parties shall be responsible for all applicable sales taxes (if any) on the portion of the Administrative Services Fee attributable to IS Services.

(iii)          The Administrative Services Fee for 2008 and thereafter shall be increased as of January 1 of each such year by an amount equal to Valero Energy’s general annual merit increase percentage for the just completed contract year.

(iv)          If VCSC exercises the VCSC Termination Option pursuant to Section 2.1(e) and has paid the Termination Fee pursuant to Section 2.2(d) below, and the Partnership Parties request the provision of one or more of the Human Resources Compensation, Payroll, Benefits and Employment Services beyond the applicable Administrative Services Termination Date, then the Operating Partnership shall pay to VCSC a monthly fee for each such Service equal to the greater of VCSC Parties’ cost in providing such Service or three times the applicable Administrative Services Fee for such Service as set out on Schedule A.

(b)           Telecommunication Services Fees.  (i)  For Telecommunication Services rendered from the Effective Date of this Agreement through December 31, 2006, the Partnership Parties shall pay to VCSC $29,570.

4

(iii)          If the Partnership Parties transfer any of the Telecommunications Services to their account prior to the applicable Telecommunications Services Termination Date, and such transfer results in reduced costs to VCSC in providing the remaining Telecommunication Services, then VCSC and the Partnership Parties shall use reasonable best efforts to agree and implement a reduction in the monthly fee that reflects the proportional cost of such transferred Telecommunication Service compared to those Telecommunication Services that VCSC is still providing at the time of the transfer.

(iv)          For local and long distance carrier service, the Operating Partnership shall pay a monthly fee of $1,728, subject to adjustment as set forth in (v) immediately below, provided that such fee shall be pro-rated following the Move Date based on the number of Partnership Parties’ employees that remain at the VCSC corporate headquarters.

(v)           The fees set forth in (ii) and (iv) immediately above shall be adjusted beginning January 1, 2008 to reflect VCSC’s actual cost to provide the Telecommunications Services.

(vi)          If the Partnership Parties elect not to take assignment of any of the third party contracts associated with the telecommunications circuits and the cell phones, pagers, Blackberries and other personal communications devices utilized by the Partnership Parties prior to the applicable Telecommunications Services Termination Date, the Operating Partnership shall reimburse VCSC for any termination fees incurred by VCSC as a result of election by the Partnership Parties.

(c)           Direct Charges.  In addition to the fees set forth above, the following items will be directly charged to the Partnership Parties (“Direct Charges”): all third party expenses directly related to the Partnership Parties, including, but not limited to, public company costs, outside legal fees, outside accounting fees, fees and expenses of external advisors and consultants, and insurance costs, including but not limited to, general liability, automobile liability, comprehensive liability, excess liability, property and directors and officers.   Payroll for employees of the Partnership Parties will also be directly billed to the Partnership Parties.

Section 2.3            Payment of Fees.

(a)           The fees to be paid by the Operating Partnership pursuant to this Agreement shall be paid by the Operating Partnership in arrears within 30 days of the end of the month; provided that payroll for employees of the Partnership Parties will be paid by the Operating Partnership no later than the first day following the end of each payroll period during the term of this Agreement.

5

(b)           To the extent reasonably practicable, all third party invoices for Direct Charges shall be submitted to the appropriate Partnership Party for payment.  For Direct Charges not paid directly by the appropriate Partnership Party, if any, VCSC shall present ▇▇▇▇▇▇ ▇▇ with an invoice within 10 days after the end of each calendar month which reflects an amount equal to all Direct Charges reimbursable to VCSC.  The Partnership Parties shall pay such sum within 30 days of the end of the applicable calendar month.

IT IS EXPRESSLY UNDERSTOOD BY THE PARTNERSHIP PARTIES THAT VCSC AND ITS AFFILIATES SHALL HAVE NO LIABILITY FOR THE FAILURE OF THIRD PARTY PROVIDERS TO PERFORM ANY SERVICES HEREUNDER AND FURTHER THAT VCSC AND ITS AFFILIATES SHALL HAVE NO LIABILITY WHATSOEVER FOR THE SERVICES PROVIDED BY ANY SUCH THIRD PARTY UNLESS IN EITHER EVENT SUCH SERVICES ARE PROVIDED IN A MANNER WHICH WOULD EVIDENCE GROSS NEGLIGENCE OR INTENTIONAL MISCONDUCT ON THE PART OF VCSC OR ITS AFFILIATES BUT VCSC SHALL, ON BEHALF OF THE PARTNERSHIP PARTIES, PURSUE ALL RIGHTS AND REMEDIES UNDER ANY SUCH THIRD PARTY CONTRACT.  THE PARTNERSHIP PARTIES AGREE THAT THE REMUNERATION PAID TO VCSC HEREUNDER FOR THE SERVICES TO BE PERFORMED REFLECT THIS LIMITATION OF LIABILITY AND DISCLAIMER OF WARRANTIES.  IN NO EVENT SHALL VCSC BE LIABLE TO THE PARTNERSHIP PARTIES OR ANY OTHER PERSON FOR ANY INDIRECT, SPECIAL, OR CONSEQUENTIAL DAMAGES RESULTING FROM ANY ERROR IN THE PERFORMANCE OF SERVICES OR FROM THE BREACH OF THIS
