(h) Trustee's Fees. The Lessee shall pay the reasonable ongoing fees -------------- and expenses of the Owner Trustee and the Indenture Trustee (including fees and expenses of their counsel) for acting as such to the extent not included 72 in Transaction Expenses. The Lessee shall have the right to receive and review any substantiation relating to such on-going expenses as the Lessee may reasonably request. 12.2. General Tax Indemnification. (a) Payment of Taxes. In the --------------------------- ---------------- event that the Lessee shall be required by applicable law to make any withholding with respect to Taxes from any payment of Rent pursuant to the Lease, (x) the Lessee shall pay such additional amounts so that after all such - required withholdings the Tax Indemnitee receives an amount equal to the Rent it would have received had such withholding not been required, (y) the Lessee shall - make such withholding and (z) the Lessee shall pay the full amount withheld to - the relevant taxing authority in accordance with applicable law.

Each Tax Indemnitee also agrees (subject to the proviso in Section 12.2(f)) to reimburse the Lessee for any amounts withheld for which such Tax Indemnitee obtains a credit or refund, within thirty (30) days after receipt of such credit or refund. Except as provided in Section 12.2(b), the Lessee agrees to pay, and to indemnify, protect, defend, save and keep harmless each Tax Indemnitee, on an After-Tax Basis, whether or not any or all of the transactions contemplated hereby are consummated in whole or in part, from and against any and all Taxes upon or with respect to (i) the Facility Assets, the Refinery or any portion - thereof or interest therein; (ii) the acquisition, purchase, sale, financing, -- leasing, subleasing, sub-subleasing and sub-sub-subleasing, 73 ownership, maintenance, repair, redelivery, alteration, insuring, control, use, operation, manufacture, assembly, delivery, possession, repossession, location, storage, importation, exportation, refinancing, refunding, transfer of title, registration, reregistration, transfer of registration, return or other disposition of all or any part of the Facility Assets or the Refinery or any interest therein; (iii) the rental payments (including, without limitation, all --- Basic Rent and Supplemental Rent), receipts or earnings arising from the Facility Assets or any portion thereof or interest therein, or payable pursuant to the Lease, or any other payment or right to receive payment pursuant to the Operative Documents (including, without limitation, any payment of principal, interest, discount or premium on or with respect to the Secured Notes); (iv) any -- Modification or replacement, removal, substitution or repair of a Component or Replacement Component; (v) the Operative Documents and any other documents - contemplated thereby and amendments and supplements thereto, or the issuance, refunding or refinancing of the Secured Notes or the Pass Through Certificates or any other document executed and delivered in connection with the consummation of the transactions contemplated by the Operative Documents or the interest of any Tax Indemnitee in any of the foregoing, or the execution, amendment, issuance or delivery of any of the foregoing; (vi) the Indenture Estate or Trust -- Estate or the property, or the income or other proceeds received with respect to the property, held by the Indenture Trustee under the Indenture or the Owner Trustee under the Trust Agreement or (vii) otherwise arising out of, with --- respect to, or in connection with the transactions contemplated by the Operative Documents.

provided, however, that -------- ------- this Section 12.2(b)(9) shall not constitute a waiver by the Lessee of its rights, if any, to assert and sue upon any claims it may have against the Tax Indemnitee by reason of such Tax Indemnitee's failure to comply with its obligations under Section 12.2(e) of this Participation Agreement; (10) Taxes imposed as a result of the trust described in the Trust Agreement or any Pass Through Trust not being treated as a grantor trust or other conduit entity for United States Federal, state or local tax purposes;

The Lessee shall either file such report, return, certification or statement (so as to show the ownership of the Facility Assets in the Owner Trustee) and send a copy of such report, return, certification or statement to the Owner Participant and the Owner Trustee, or, where not so permitted to file, shall notify the Owner Participant and the Owner Trustee of such requirement within a reasonable period of time prior to the due date for filing (without regard to any applicable extensions) and prepare and deliver such report, return, certification or statement to the Owner Participant and the Owner Trustee. In addition, within a reasonable time prior to the time such report, return, certification or statement is to be filed the Lessee shall, to the extent permitted by law, cause all billings of such Taxes to be made to each Tax Indemnitee in care of the Lessee, make payment thereof and furnish written evidence of such payment.

Any Tax indemnified hereunder shall be paid directly -------- when due to the applicable taxing authority if direct payment is permitted, or shall be reimbursed to a Tax Indemnitee on demand if paid by such Tax Indemnitee in accordance herewith. Except as otherwise provided in this Section 12.2, all amounts payable to a Tax Indemnitee hereunder shall be paid promptly in immediately available funds, but in no event later than the later of (i) ten - (10) days after the date of such demand or (ii) ten (10) days before the date -- the Tax to which such amount payable hereunder relates is due or is to be paid and any such demand shall be accompanied by a written statement (which written statement shall, at the Lessee's request, be verified by a nationally recognized independent accounting firm mutually acceptable to the Lessee and the Tax Indemnitee, such verification to be at the Lessee's expense unless such accountants determine that the amount payable by the Lessee is less than 95% of the amount shown on such written statement, in which event the cost of such verification will be paid by the Tax Indemnitee) describing in reasonable detail the Tax and the computation of the amount payable. In the case of a Tax subject to indemnification under this Section 12.2 which is properly subject to a contest in accordance with Section 12.2(e), the Lessee (i) shall be obligated to - make any advances with respect to such Tax whenever required under Section 12.2(e) and (ii) shall pay such Tax (in the amount finally determined to be -- owing in such contest) prior to the latest time permitted by the relevant taxing authority for timely payment after a Final Determination. (e) Contests; Refunds. (i) In the event a taxing jurisdiction makes ----------------- a claim with respect to any Tax for which the Lessee may be liable under this Section 12.2 (a "Tax Claim"), the Lessee may cause the applicable Tax Indemnitee --------- to contest such Tax Claim (and any judicial decision with respect thereto) as set forth herein. In the event any Tax Indemnitee receives notice of a Tax Claim or potential Tax Claim which may be indemnified under this Section 12.2, such Tax Indemnitee shall promptly notify the Lessee thereof in writing. If requested by the Lessee in writing within thirty (30) days of receipt of such notice (or, if sooner, on or before the last date upon which the contest of such Tax can be initiated, provided that the Tax Indemnitee's notice to the Lessee discloses such date), such Tax Indemnitee shall, upon receipt of an indemnity satisfactory to it whereby the Lessee shall have agreed to pay to such Tax Indemnitee all reasonable costs, expenses, legal and accountants' fees and disbursements incurred by 80 such Tax Indemnitee in connection with contesting such Tax Claim, and at the expense of the Lessee, contest the imposition of any Tax Claim by (1) resisting - payment thereof, if such Tax Indemnitee in its reasonable discretion shall determine such course of action to be appropriate; (2) not paying the same - except under protest, if protest is necessary and proper or (3) if payment shall - be made, using reasonable efforts to obtain a refund thereof in appropriate administrative and judicial proceedings, or both. If such contest shall involve payment of the Tax Claim, the Lessee shall have advanced to such Tax Indemnitee the amount of such payment plus interest, penalties and additions to tax with respect thereto on an interest-free basis, and shall have agreed to indemnify the Tax Indemnitee, on an After-Tax Basis, for any adverse tax consequences resulting from such advance. In no event shall any Tax Indemnitee be required or the Lessee be permitted to contest any Taxes for which the Lessee is obligated to indemnify pursuant to this Section 12.2 unless: (i) such Tax - Indemnitee shall have received the opinion of tax counsel selected by the Lessee (which may be an employee of the Lessee or an Affiliate) furnished at the Lessee's sole expense to the effect that a reasonable basis consistent with ABA Opinion 85-352 exists for contesting such claim (and provided that no appeal shall be required to the United States Supreme Court); (ii) no Specified Lease -- Event of Default shall have occurred and be continuing (unless the Lessee shall have provided security reasonably satisfactory to such Tax Indemnitee securing the Lessee's performance of its obligations under this Section 12.2) and (iii) --- such Tax Indemnitee shall have determined that the action to be taken will not result in any risk of imposition of criminal penalties or any substantial danger of sale, forfeiture or loss of the Facility Assets or any portion thereof or any interest therein. If requested by the Lessee and if permitted by applicable law, the Lessee may contest, at its own expense, the imposition of any Tax Claim. In any contest controlled by the Tax Indemnitee, such Tax Indemnitee will consult in good faith with the Lessee and its counsel and submit to the Lessee and its counsel for review and comment, and consider in good faith any and all suggestions made with respect to, any item to be submitted to a taxing authority or a court in connection with the contest and permit the Lessee to participate in a reasonable manner in the conduct of the contest. Upon the written request of the affected Tax Indemnitee, the Lessee will advise such Tax Indemnitee of the status of any contest being conducted by the Lessee pursuant to this Section 12.2(e). 81 A Tax Indemnitee shall not make, accept or enter into a settlement or other compromise with respect to any Taxes indemnified pursuant to this Section 12.2 (which proceeding the Tax Indemnitee is required to continue), or forego or terminate any such proceeding with respect to Taxes indemnified pursuant to this Section 12.2, without the prior written consent of the Lessee. Notwithstanding the foregoing, if a Tax Indemnitee refuses to contest any Tax Claim or effects a settlement or compromise of any such Tax that the Tax Indemnitee is required to contest or otherwise terminates any such contest without the prior written consent of the Lessee, such Tax Indemnitee shall be deemed to have waived its right to any indemnity payment by the Lessee that would otherwise be payable by the Lessee pursuant to this Section 12.2 in respect of such Tax Claim, and such Tax Indemnitee shall promptly pay to the Lessee any amounts previously paid or advanced by the Lessee pursuant to this Agreement with respect to such Tax Claim (other than amounts advanced with respect to costs and expenses of the contest). (ii) Upon receipt by any Tax Indemnitee of a repayment or refund of all or any part of any Tax which the Lessee shall have paid for, or advanced to, such Tax Indemnitee or for which the Lessee shall have reimbursed such Tax Indemnitee pursuant to this Section 12.2, such Tax Indemnitee shall pay to the Lessee, as promptly as practicable after the receipt thereof, the amount of such repayment or refund plus any interest received by, or credited to, such Tax Indemnitee on such amounts net of Taxes thereon plus the amount of any net tax savings actually realized by such Tax Indemnitee as a result of the payment made to the Lessee; provided, however, that: if there is a subsequent loss of -------- ------- any such tax savings or refund realized by the Tax Indemnitee, such loss shall be treated as a Tax for which the Lessee must indemnify such Tax Indemnitee pursuant to this Section 12.2. The amount payable to the Lessee in respect of tax benefits or refunds shall, at the Lessee's request, be subject to verification by independent accountants selected by the Tax Indemnitee and reasonably satisfactory to the Lessee, at the Lessee's expense unless such accountants determine that the amount payable to the Lessee is at least 5% more than the amount so computed by the Tax Indemnitee, in which event the cost of such verification will be paid by the Tax Indemnitee. (f) Tax Savings. If, by reason of any payment made to or for the ----------- account of a Tax Indemnitee by the Lessee pursuant to this Section 12.2 or the circumstances giving 82 rise thereto, such Tax Indemnitee at any time realizes a reduction in any Taxes for which the Lessee is not required to indemnify such Tax Indemnitee pursuant to this Section 12.2 and which was not taken into account previously in computing such payment by the Lessee to or for the account of such Tax Indemnitee, then such Tax Indemnitee shall promptly pay to the Lessee an amount equal to such actual reduction in Taxes plus the amount of any additional reduction in Taxes realized by such Tax Indemnitee or any related Tax Indemnitee as a result of any payment made by such Tax Indemnitee pursuant to this sentence; provided, however, that if there is a subsequent loss of any such tax -------- ------- savings or refund realized by the Tax Indemnitee, such loss shall be treated as a Tax for which the Lessee must indemnify such Tax Indemnitee pursuant to this Section 12.2. Each Tax Indemnitee shall in good faith use diligence in filing its tax returns and in dealing with the relevant taxing authorities to seek and claim any tax benefit that would result in any such reduction in Taxes or any refund of any Taxes payable or indemnifiable by the Lessee hereunder. (g) Definition of Owner Participant. For purposes of this Section ------------------------------- 12.2, the term "Owner Participant" and the term Tax Indemnitee as applied to the Owner Participant shall include any member of an affiliated group, within the meaning of Section 1504 of the Code (or any successor provision thereof), or comparable state or local law provisions of which the Owner Participant is, or may become, a member, if consolidated, joint or combined returns are filed for such affiliated group for Federal, state or local income tax purposes. The Owner Participant undertakes on behalf of such other members of its affiliated group to perform or cause to be performed all obligations of such affiliated group hereunder. 12.3. No Guarantee. Nothing in Section 12.1 or 12.2 shall be ------------ construed as a guaranty by the Lessee of any residual value in or useful life of the Facility Assets or as a guaranty of the Secured Notes or the Pass Through Certificates. Section 13. Transfer of Owner Participant's Interest. ------------------------------- -------- 13.1. Restrictions on Transfer. Without the prior written consent ------------------------ of, so long as the Lease shall be in effect, the Lessee, and, so long as the Lien of the Indenture shall be in effect, the Indenture Trustee, the Owner Participant shall not, directly or indirectly, assign, 83 convey or otherwise transfer (whether, except in the case of Fleet National Bank or any of its successors, by merger, consolidation or other similar transaction) any of its right, title or interest in and to the Trust Estate, this Participation Agreement, the Trust Agreement or any other Operative Document, except in accordance with the terms and conditions of this Section 13. 13.2.

89 (b) the aggregate principal amount of the Refunding Secured Notes shall not exceed by more than 5% the then Outstanding principal amount of the Refunded Secured Notes; (c) if within twenty (20) days after the request by the Lessee to effect the refunding or refinancing, the Owner Participant provides the Lessee with a written opinion of independent tax counsel, selected by the Owner Participant and satisfactory to the Lessee, identifying any unindemnified and adverse tax consequences to the Owner Participant resulting from the refinancing or refunding, the Lessee shall have agreed to indemnify the Owner Participant against such adverse tax consequences in a manner and in form and scope reasonably satisfactory to the Owner Participant; provided, however, that, in the absence of a change in the -------- ------- Code or the Treasury Regulations (other than with respect to the alternative minimum tax) that is enacted or adopted after the Closing Date that affects the Tax Pricing Assumptions set forth in Schedule 2, none of the following shall be treated as causing an adverse tax consequence under Section 861 of the Code or with respect to the status of the Lease as a "true lease" for federal income tax purposes: (i) any refinancing or - refunding that complies with the provisions of this Section 15.1 and has a term and average life not more than six (6) months longer than the term and average life of the Refunded Secured Notes;

(e) if the Refunding Date is a date during the Basic Lease Term that is not a Basic Rent Payment Date, the Lessee and the Owner Trustee will amend the Lease such that the Lessee shall on the Refunding Date prepay that portion of the next succeeding installment of Basic Rent to the extent necessary to pay the aggregate 90 interest accrued on the Refunded Secured Notes not payable with the proceeds of the Refunding Secured Notes; (f) the identity of the Owner Participant shall not be disclosed in offering materials used in any such refunding or refinancing pursuant to a public offering; (g) the Owner Trustee will enter into an agreement to provide for the issuance and securing thereunder of the Refunding Secured Notes in like manner as the Refunded Secured Notes and/or will enter into such amendments and supplements to the Indenture as may be necessary to effect a refunding or refinancing under this Section 15.1, which agreements, amendments and/or supplements shall be reasonably satisfactory in form, scope and substance to the Owner Participant and which, taken as a whole, shall not be less favorable to the Owner Participant or the Owner Trustee than the terms and conditions of the Refunded Secured Notes; (h) the parties hereto shall execute and deliver such amendments to the Operative Documents and such additional documents, certificates and opinions as shall be reasonably requested by, and reasonably acceptable to, the Lessee, the Owner Trustee, the Owner Participant and the Indenture Trustee, including, but not limited to, such documents, financing statements and opinions as are reasonably necessary to confirm that the refunding or refinancing of all Secured Notes of the series as to which the refunding or refinancing is occurring is being carried out; and (i) the Refunding Secured Notes may not rank senior (but may rank junior) in any respect to other Secured Notes Outstanding under the Indenture and will be denominated in U.S. Dollars and have a maturity not exceeding the Basic Lease Term or, if the Lessee shall have exercised an option to renew the Lease, the applicable Renewal Term.

The Secured Notes may not be refunded or refinanced other than at the request of the Lessee. 91 15.2. Notice.

The Lessee will provide notice promptly to such Persons in the event that it determines not to proceed with such proposed refunding or refinancing pursuant to Section 15.1. Section 16. Beneficial Interest Purchase Option. ----------------------------------- 16.1. Option to Purchase. In the event and at the time that the ------------------ Lessee has the right to purchase the Facility pursuant to Section 6.1 or 7.3(a)(i) of the Lease, the Lessee, in lieu of exercising such right, may elect to purchase or cause a designee of the Lessee to purchase the right, title and interest of the Owner Participant in and to the Trust Estate (the "Beneficial ---------- Interest") at a purchase price equal to the excess of (i) the applicable - -------- - purchase price payable under Section 6.1 or 7.3(a)(i), as the case may be (and payable, in the case of the EBO Purchase Price, in installments at the same times and subject to the same conditions that the EBO Purchase Price may be paid in installments under Section 6.2(f) of the Lease), over (ii) the Outstanding -- principal and accrued interest on the Secured Notes as of the applicable purchase date (after giving effect to the payment of all amounts required to be paid by the Lessee pursuant to Section 16.2(b)) (the "Beneficial Interest -------------------- Purchase Price"). It is intended among the parties hereto that the purchase of - -------------- the Beneficial Interest by the Lessee or any Affiliate thereof shall not effect a merger of the Lessee's interest, as lessee, in the Lease and the beneficial interest in the Trust Estate to be purchased by the Lessee or any such Affiliate. 16.2. Notice of Election; Manner of Purchase; Transfer After --------------------------------------- -------------- Purchase. (a) In order to exercise the right to purchase the Beneficial Interest pursuant to Section 16.1, the Lessee shall notify the Owner Participant irrevocably in writing no later than thirty (30) days prior 92 to the applicable purchase date under Section 6.1 of the Lease or applicable Termination Date under Section 7.3(a) of the Lease that it desires to purchase, or cause such designee to purchase, the Beneficial Interest, in which case the purchase of the Facility pursuant to Section 6.1 or 7.3 of the Lease shall not occur. (b) On the date of purchase, upon receipt by the Owner Participant of the Beneficial Interest Purchase Price, and an amount equal to that portion of all Basic Rent due on or prior to such date of purchase that would be distributable to the Owner Participant under the Indenture (but excluding any Basic Rent payable in advance on such date of purchase) and all Supplemental Rent due by the Lessee to or distributable to the Owner Participant to and including such date of purchase (without giving effect to any applicable grace periods), the Owner Participant shall transfer the Beneficial Interest free and clear of all Liens to the Lessee or its designee pursuant to an instrument of conveyance in form and substance reasonably satisfactory to the Lessee or its designee, and shall provide to the Lessee or such designee such other instruments, documents and opinions as the Lessee may reasonably request to evidence the valid consummation of such transfer. (c) Each of the Participants, the Owner Trustee and the Indenture Trustee, at the cost and expense of the Lessee, will cause to be promptly and duly taken, executed, acknowledged and delivered all such further acts, documents and assurances as the Lessee reasonably may request in order to carry out the intent and purposes of this Section 16 and the transactions contemplated hereby. (d) As a condition to exercise of the right to purchase the Beneficial Interest pursuant to Section 16.1 (unless the Lessee shall assume the obligations of the Owner Trustee pursuant to the next sentence), on the date of purchase, the Lessee shall have provided to the Indenture Trustee an opinion of counsel for the Lessee or its designee (which may, in each case, be internal counsel), dated the date of purchase, which, subject to usual or customary exceptions, shall be to the effect that, upon consummation of such purchase, this Participation Agreement and the Trust Agreement constitute the legal, valid and binding obligations of the Lessee or such designee, enforceable against the Lessee or such designee, in accordance with their respective terms except as the same may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the rights of creditors 93 generally and by general principles of equity. In the event the Lessee or such designee is unable to provide such opinion, concurrently with the purchase of the Beneficial Interest, (i) the Lessee or such designee may assume the - obligations of the Owner Trustee under the Secured Notes and under the Indenture in accordance with and with the effect provided in Section 3.04 of the Indenture and Section 11.6 hereof, and upon such assumption the Lessee or such designee shall have the right to terminate the Trust Agreement or (ii) the Lessee may -- revoke its purchase, election or other notice under the Lease, in which event the Lease shall continue as set forth therein.
