Alterations. During the Ground Lease Term, subject to the terms ----------- and conditions of the Operative Documents and the Support Agreements, the Ground Lessee, in its discretion, may from time to time alter or improve, or cause to be altered or improved, the Land or any part thereof in any manner it deems necessary or desirable to carry on any activity permitted under Section 6.1, including, without limitation, any alteration, demolition or removal of any existing buildings, equipment, machinery or other structures or items of personal property or fixtures and any grading or landscaping of the Land. 6.3.

The Ground Lessor has no obligation to make or pay for any repairs, replacements, restorations, improvements, alterations or additions whatsoever on or to the Site or to the Facility Assets, except such as may be necessary to comply with its express obligations hereunder. 6.4. Damage to Refinery. Notwithstanding anything to the contrary ------------------ contained in this Ground Lease, in connection with the acquisition, construction, design, installation, ownership, maintenance, use, testing, operation, modification, alteration, improvement or removal of, or any other action or inaction with respect to, the Facility Assets or the use or possession of the Land, the land underlying the Easements or the Easements, the Ground Lessee shall (a) avoid any damage to or material - 11 interference with the use, possession and operation of the Refinery (including, without limitation, pipes and other property that run through or are located on the Site but are not part of the Facility Assets); (b) repair any damage to the - Site or the Refinery caused by any of its activities and (c) make all - commercially reasonable efforts to coordinate with the Ground Lessor regarding the scheduling of the use of any roadways and other Easements within the Refinery and otherwise so as to prevent any injuries to Persons or property or material interference with the use, maintenance and operation of the Refinery. Section 7. Compliance with Governmental Requirements. The Ground ----------------------------------------- Lessee at its expense will comply in all material respects with all Governmental Rules applicable to the Site or applicable to the Ground Lessee's interest in or operations at the Site, and with all other Governmental Rules to the extent any failure to comply with such other Governmental Rules would result in a Lien upon the Ground Lessor's interest in the Site, the material danger of the loss or impairment of the title to the Site or any portion of the Refinery or the imposition or threatened imposition of any criminal or material civil penalties on the Ground Lessor or any other Person entitled to access to or use of any portion of the Site or the Refinery.

For the avoidance of doubt, the Ground Lessee will not, directly or indirectly, create or permit to be created or remain, and will promptly discharge, any Lien on the Refinery arising through the actions or inactions of the Ground Lessee. The obligations in this Section 8 shall survive the expiration or other termination of this Ground Lease. (b) The Ground Lessor will not directly or indirectly create or permit to be created or to remain, and 12 will promptly discharge, any Lien (other than any Permitted Lien) on the Ground Lessee's interest in the Facility Assets or any part thereof.

No such payment, performance or discharge by or on behalf of the Lessee shall be deemed an acknowledgment by the Ground Lessor of the Lessee as the ground lessee hereunder, or a merger of the Facility Assets Lease with this Ground Lease or a merger of the estate of the sublessor under the Facility Assets Lease with the estate of the Lessee thereunder. The Ground Lessee will not consent to any amendment, modification or supplement of or to the Facility Assets Lease which would limit the obligation of the Lessee set forth therein to pay, perform the obligations and discharge the liabilities of the Ground Lessee hereunder without the prior written consent of the Ground Lessor. 9.2. Rights of the Lessee. For so long as the Facility Assets Lease -------------------- shall be in effect, if this Ground Lease has terminated or been rejected or disaffirmed as described in the first sentence of Section 14.4 and if at the time no Leasehold Mortgagee shall have timely exercised its right to require the Ground Lessor to enter into a new ground lease under Section 14.4, the Ground Lessor shall give the Lessee notice thereof, and at any time within thirty (30) days after receipt of such notice, the Lessee may require the Ground Lessor to enter into such a new lease with the Lessee in order to create between the Ground Lessor and the Lessee the relationship of lessor and lessee with respect to the Site, provided that any such new lease between the Ground Lessor and the -------- Lessee shall contain all of the terms and conditions of this Ground Lease as provided in Section 14.4. This Section 9.2 is entered into by the Ground Lessor for the benefit of the Lessee, shall survive 13 the termination, rejection or disaffirmance of this Ground Lease and may be specifically enforced by the Lessee against the Ground Lessor. Section 10. Loss. ---- 10.1. Event of Loss. (a) During the term of the Facility Assets ------------- Lease, if an Event of Loss shall occur which Event of Loss shall result in the termination of the Facility Assets Lease, this Ground Lease shall terminate as of the date of termination of the Facility Assets Lease, and, subject to Sections 8 and 11.1, the Ground Lessee shall have no liability hereunder for any Primary Rent or any Additional Rent which would otherwise accrue or be payable hereunder after such date.

Other Damage to Site. Whether or not the Facility Assets Lease -------------------- shall have expired or terminated, in the event of damage to, or loss, condemnation or requisition of, the Facility Assets or the Site which does not constitute an Event of Loss, this Ground Lease shall remain in full force and effect with no adjustment to Primary Rent or Additional Rent. All Site Awards accruing to the Ground Lessor or the Ground Lessee on account of such damage to, or loss, condemnation or requisition of the Site not constituting an Event of Loss shall be held by or paid over to the Ground Lessor and applied by or on behalf of the Ground Lessor, first, to the restoration of the Site, to the ----- extent the Ground Lessor deems such restoration feasible and necessary for the operation of the Facility Assets for their intended purpose, and second, the ------ balance, if any, thereafter remaining shall be paid to or retained by the Ground Lessor. 14 10.3. Allocation of Awards Upon Event of Loss. (a) If an Event of --------------------------------------- Loss under the Facility Assets Lease shall occur during any period when the Facility Assets Lease shall be in effect, which Event of Loss results in termination of this Ground Lease pursuant to Section 10.1(a), (i) all Site - Awards accruing to the Ground Lessor or the Ground Lessee on account of such Event of Loss shall be retained by or paid over to the Ground Lessor and (ii) -- all Facility Assets Awards shall be distributed pursuant to the Facility Assets Lease. (b) If an Event of Loss shall occur with respect to the Site or the Facility Assets during any period when the Facility Assets Lease shall not be in effect, which Event of Loss results in the termination of this Ground Lease pursuant to Section 10.1(b), (i) all Site Awards accruing to the Ground Lessor - or the Ground Lessee on account of such Event of Loss shall be apportioned between the Ground Lessor and the Ground Lessee in the same ratio as the ratio of (1) the value of the Ground Lessor's remainder interest in the Site - (determined as at the end of the Ground Lease Term, as then in effect, and discounted to present value at the Debt Rate), plus all Primary Rent (or, for periods for which Primary Rent has not been determined, the Fair Market Rental Value of the Site as determined by mutual agreement of the Ground Lessor and the Ground Lessee, or, if they shall fail to agree upon the Fair Market Rental Value of the Site within thirty (30) days after a request to do so by either party, pursuant to the Appraisal Procedure) payable for the remainder of the Ground Lease Term, discounted to present value at the same rate, to (2) the value of - the Ground Lessee's leasehold interest in the Site, in each case determined as though no such Event of Loss had occurred, and (ii) all Facility Assets Awards -- shall be retained by or paid over to the Ground Lessee. (c) In any case in which this Section 10.3 requires that Site Awards be apportioned between the Ground Lessor and the Ground Lessee, or in any case where no separate Facility Assets Award or Site Award is made with respect to the Facility Assets and the Site, or in any case involving any properties of the Ground Lessor other than the Site where no separate Site Award is made with respect to the Site and such other properties, such apportionment shall be as determined by good faith negotiations by the Ground Lessor and the Ground Lessee, consistent with the provisions of this Section 10. If the Ground Lessor and the Ground Lessee shall fail to agree within thirty (30) days after a 15 request to do so by either party, the apportionment shall be determined in accordance with the Appraisal Procedure. (d) The payment and application of Site Awards and Facility Assets Awards set forth in Sections 10.2 and 10.3 shall apply notwithstanding the fact that, in any Event of Loss, Site Awards and Facility Assets Awards may be separately evaluated and paid to the Ground Lessor and the Ground Lessee. (e) The Ground Lessor shall have the right to direct all proceedings under this Section 10, provided that all material decisions affecting the rights -------- of the Ground Lessee under this Section 10 shall be subject to the consent of the Ground Lessee (which consent shall not be unreasonably withheld). Subject to the foregoing, the Ground Lessor shall have the right to institute and prosecute such proceedings as may be reasonably required to obtain an adequate Site Award for damages to all or any portion of the Site resulting from any Event of Loss, such proceedings to be brought in the name of the Ground Lessor or the Ground Lessee, or in the names of both of them. The cost of such proceedings shall be borne by the Ground Lessor. Section 11. Indemnification; Insurance. -------------------------- 11.1. INDEMNIFICATION.

(a) Subject ---------------------------------------------- to the Lessee's purchase option described in Section 12.3(b), if the Ground Lessee has elected or is deemed to have elected the option in Section 12.2(b)(y), the Lessee, at its own expense, shall be required to dismantle the Facility Assets and deliver the components thereof, appropriately packaged or crated, to the nearest public wharf not later than one year after the expiration or earlier termination of this Ground Lease. The Lessee shall give the Ground Lessor at least sixty (60) days prior written notice of the commencement of any such dismantlement and removal, and the Lessee shall repair any damage to the Refinery or the Site resulting from any such dismantlement and removal.

Within thirty (30) days of the Ground Lessee's request for - dismantlement pursuant to Section 12.3(a), the Lessee and the Ground Lessee shall commence negotiations to determine the Post-Term Fair Market Sales Value of the Facility Assets. If the Lessee and the Ground Lessee are unable to agree within thirty (30) days as to the Post-Term Fair Market Sales Value after a request to do so by either party, the Post-Term Fair Market Sales Value shall be determined by the Appraisal Procedure. The Lessee shall notify the Ground Lessee and the Ground Lessor of its decision to exercise this purchase option no later than six (6) months after the expiration or earlier termination of this Ground Lease. Upon payment of the purchase price of the Facility Assets, the Ground Lessee shall transfer all right, title and interest of the Ground Lessee in and to the Facility Assets, as is and where is, to the Lessee or as the Lessee may direct, free and clear of Lessor's Liens and Owner Participant's Liens but otherwise without any representation or warranty. (c) Upon the expiration or earlier termination of this Ground Lease, the Facility Assets may remain on the Land or the land underlying the Easements during the period required for the Lessee to perform its dismantlement obligation under Section 12.3(a); provided that during such dismantlement period -------- the Ground Lessee shall have no right to enter upon, occupy or use the Site or any part thereof, and provided further that during such period the Lessee shall -------- ------- have the right to enter upon, occupy or use the Site or any part thereof solely for the purpose of dismantling and removing the Facility Assets pursuant to such Section 12.3(a), and during such period the Lessee shall be responsible for all utilities and other expenses in connection with the dismantlement and removal of the Facility Assets and any Ground Lease Impositions allocable to the Facility Assets.

Any Ground Lease Impositions levied or assessed for a period beginning before the Closing Date or ending after the Ground Lease Term shall be prorated between the Ground Lessor and the Ground Lessee as of the applicable date. In case of any special assessment levied or assessed during the Ground Lease Term which is payable in installments, the Ground Lessee shall only be obligated to pay those installments coming due during the Ground Lease Term. 13.2. Allocation of Ground Lease Impositions. In the absence of a -------------------------------------- separate assessment of the Site and the Facility Assets and on other adjacent properties, the Ground Lessee's allocable share of such Ground Lease Impositions shall be equal to the amount of such Ground Lease Impositions multiplied by a fraction the numerator of which is the sum of the Fair Market Sales Value of the portion of the Facility Assets and the Site subject to such Ground Lease Impositions and the denominator of which is the Fair Market Sales Value of the total properties subject to such Ground Lease Impositions, subject to appropriate adjustment if the basis for assessment of the Ground Lease Impositions is not the value of the property which is subject thereto. In the event the Ground Lessor and the Ground Lessee are unable to agree on the respective fair market values referred to in the preceding sentence within thirty (30) days after a request to do so by either party, such values shall be determined by the Appraisal Procedure. 13.3. Direct Payment of Ground Lease Impositions. Unless otherwise ------------------------------------------ required by a Leasehold Mortgagee, the Ground Lessee shall pay Ground Lease Impositions directly to the appropriate governmental authority and, upon written request of the Ground Lessor, shall forward to the Ground Lessor receipts or other appropriate evidence of such payment.

Transfers by the Ground Lessee. ------------------------------ 14.1. Subletting and Assigning. (a) Subject to the terms and ------------------------ conditions of this Ground Lease and the other Operative Documents, the Ground Lessee shall have the right to sublet, in whole or in part, or to assign, in whole or in part, its interest hereunder without the consent of the Ground Lessor, provided that (i) so long as the Facility Assets Lease is in effect, the -------- - Ground Lessee may only sublet or assign any interest hereunder (1) pursuant to - Section 2.4 of the Facility Assets Lease or (2) concurrently with the assignment - to a successor Owner Trustee of its interests in the Facility Assets pursuant to, and to the extent permitted by, the Operative Documents, and (ii) after the -- expiration or the earlier termination of the Facility Assets Lease, the Ground Lessee may make an assignment of all of its interest under this Ground Lease and in and to the Facility Assets to any Person permitted by the Operative Documents only if (1) such Person assumes, in writing in form and substance satisfactory - to the Ground Lessor, all of the obligations and liabilities of the Ground Lessee hereunder and liabilities thereunder and (2) except in the case of a - purchase of the Facility by an unaffiliated third party pursuant to Section 7.3(a)(ii) or Section 16 of the Facility Assets Lease or if the transfer meets the requirements of Sections 13.2(a), (b), (e) and (i) of the Participation Agreement, the Owner Participant shall guarantee in full, to the satisfaction of the Ground Lessor, the obligations of the Ground Lessee (including any successor or assign). Upon an assignment pursuant to Section 14.1(a)(ii), the Ground Lessee will be released from all liability thereafter accruing under this Ground Lease from and after the effective date of such assignment, and the assignee shall have all the rights and obligations of the Ground Lessee hereunder. (b) In the event the Ground Lessee purports to sublet or assign its interest hereunder in a manner other than as expressed in Section 14.1(a), such sublease or assignment shall be null and void and of no effect for any purposes whatsoever as to the Ground Lessor. 14.2. Leasehold Mortgages; Rights of Leasehold Mortgagees. (a) --------------------------------------------------- During the term of the Facility Assets Lease, the Ground Lessee may not encumber its interest in the Site other than by granting the Lien of the Indenture. After the expiration or earlier termination of the Facility Assets Lease, the Ground Lessee may enter into one or more mortgages or deeds of trust encumbering the Ground Lessee's 22 interest in the Site which secures, among other things, the payment of indebtedness of the Ground Lessee for money borrowed and the performance by the Ground Lessee of related obligations, notice of which mortgage or deed of trust (including the name and address of the holder thereof) has been given to the Ground Lessor by the Ground Lessee or the mortgagee thereunder (each, a "Leasehold Mortgage"). Any documentation relating to such Leasehold Mortgage - ------------------- shall be reasonably acceptable to the Ground Lessor, and any filings or other recordations relating to such Leasehold Mortgage shall be in form reasonably satisfactory to the Ground Lessor and shall be made by the Ground Lessor or in a manner reasonably satisfactory to the Ground Lessor. The Ground Lessor acknowledges that the Indenture constitutes a "Leasehold Mortgage" for all purposes hereof. The Indenture Trustee or any other holder of a Leasehold Mortgage (a "Leasehold Mortgagee") may, but shall not be obligated to, make any ------------------- payment or perform any act required hereunder to be made or performed by the Ground Lessee with the same effect as if made or performed by the Ground Lessee, provided that no entry by such Leasehold Mortgagee upon the Site for such - -------- purpose shall constitute or be deemed to be an eviction of the Ground Lessee or shall waive or release the Ground Lessee from any obligation or default hereunder (except any obligation or default which shall have been fully and irrevocably performed or corrected by such payment or performance by such Leasehold Mortgagee). In no event shall the Ground Lessor's interest in the Site be pledged as security for, or subordinated to, any mortgage or other encumbrance without the prior written consent of the Ground Lessor. (b) If a Ground Lease Event of Default shall occur, written notice to that effect shall be sent by the Ground Lessor to each Leasehold Mortgagee, and the Ground Lessor shall take no action to terminate this Ground Lease or to interfere with the occupancy, use or enjoyment of the Site or the Facility Assets, prior to the expiration of any period for the cure thereof provided in this Section 14.2(b). (i) If such Ground Lease Event of Default shall be a default in the payment of any amounts hereunder (including, without limitation, any Primary Rent or any Additional Rent), then such Leasehold Mortgagee shall have twenty (20) days after the giving of the notice referred to in the first sentence of this Section 14.2(b) to remedy such default. 23 (ii) If such Ground Lease Event of Default is not a payment default and such default can be remedied by such Leasehold Mortgagee without obtaining possession of the Site, then such Leasehold Mortgagee shall have sixty (60) days after the giving of the notice referred to in the first sentence of this Section 14.2(b) to remedy such default. (iii) If such Ground Lease Event of Default shall be a default which can only be remedied by such Leasehold Mortgagee upon obtaining possession of the Site and such Leasehold Mortgagee or its nominee shall obtain such possession with reasonable diligence, through foreclosure, appointment of a receiver or otherwise, then such Leasehold Mortgagee shall have fifteen (15) days after obtaining such possession to remedy such default. Any default remedied or cured by a Leasehold Mortgagee in accordance with this Section 14.2 shall be deemed cured for all purposes of this Ground Lease. If, during the pendency of any possession referred to in subparagraph (iii) of this Section 14.2(b) prior to transfer of the Ground Lessee's interest in the Site to such Leasehold Mortgagee, its nominee or any purchaser by fore- closure or otherwise under the Leasehold Mortgage, such Leasehold Mortgagee shall comply with the requirements of such subparagraph, shall pay or cause to be paid to the Ground Lessor all Primary Rent accruing during such period, and shall perform or cause to be performed all other obligations of the Ground Lessee hereunder accruing during such period except those which cannot with the exercise of reasonable diligence be performed by or on behalf of such Leasehold Mortgagee, then the Ground Lessor shall have no right to terminate this Ground Lease or to interfere with such possession during such pendency based on such unperformed obligations. (c) Subject to Section 14.3, if any Leasehold Mortgagee or its nominee or any other Person (collectively, a "Ground Lease Transferee") shall ----------------------- acquire all or substantially all of the Ground Lessee's interest in the Site and the Facility Assets as a result of a default under any Leasehold Mortgage, whether by foreclosure, power of sale, voluntary conveyance, or otherwise, and if such Ground Lease Transferee shall have assumed in writing in form and substance reasonably satisfactory to the Ground Lessor all obligations and liabilities of the Ground Lessee under this 24 Ground Lease, then (1) such Ground Lease Transferee shall be liable for the - performance or observance of agreements, obligations, covenants or conditions under this Ground Lease, and all liabilities with respect thereto and (2) such - Ground Lease Transferee shall be entitled to all of the benefits available to the Ground Lessee under this Ground Lease. 14.3. Assignment by Leasehold Mortgagees, etc. The sale, transfer or --------------------------------------- assignment of all or any part of the Ground Lessee's interest in the Site to any Ground Lease Transferee on foreclosure or other enforcement of the lien of any Leasehold Mortgagee shall be of no force and effect unless (i) during the term - of the Facility Assets Lease, the sale, transfer or assignment of all or any part of the Ground Lessee's interest in the Site to any Ground Lease Transferee is consistent with the terms of the Operative Documents or (ii) after the -- expiration or earlier termination of the Facility Assets Lease, the Ground Lease Transferee shall meet the requirements of Sections 13.2(a), (b), (e) and (i) of the Participation Agreement and has assumed, in a writing in form and substance satisfactory to the Ground Lessor, all of the obligations and liabilities of the Ground Lessee hereunder. 14.4. New Ground Lease. If this Ground Lease shall terminate as a ---------------- result of a default by the Ground Lessee which cannot be cured or remedied or this Ground Lease shall be rejected or disaffirmed in any bankruptcy, insolvency or reorganization proceeding affecting the Ground Lessee, then any Leasehold Mortgagee or a Person designated by such Leasehold Mortgagee (in either case, the "New Ground Lessee"), shall have the right, exercisable by notice to the ----------------- Ground Lessor within sixty (60) days after the effective date of such termination, rejection or disaffirmance, to enter into a new lease of the Site with the Ground Lessor, the term of which shall begin on the date of the termination, rejection or disaffirmance of this Ground Lease and shall continue for the remainder of the originally scheduled Ground Lease Term. The new lease shall otherwise contain the same terms and conditions as those set forth herein, except for requirements which are no longer applicable or have already been performed. The provisions of this Section 14.4 shall survive the termination, rejection or disaffirmance of this Ground Lease and shall continue in full force and effect thereafter to the same extent as if this Section 14.4 were a separate and independent contract among the Ground Lessor, the Ground Lessee and each Leasehold Mortgagee. From the date on which 25 any Leasehold Mortgagee shall serve upon the Ground Lessor notice of the exercise of its right to a new lease, such Leasehold Mortgagee may use and enjoy the Site without hindrance by the Ground Lessor. If at any time there is more than one Leasehold Mortgagee, the Leasehold Mortgagee that, in the reasonable determination of the Ground Lessor, is most senior in lien priority shall, in the absence of agreement to the contrary among all Leasehold Mortgagees, be the only Leasehold Mortgagee entitled to the benefits of this Section 14.4. 14.5. Personal Liability of Leasehold Mortgagee, etc. No Leasehold ---------------------------------------------- Mortgagee shall become personally liable for the performance or observance of any agreements, obligations and covenants or conditions to be performed or observed by the Ground Lessee, or any liabilities with respect thereto, unless and until such Leasehold Mortgagee becomes the owner of the Ground Lessee's interest hereunder upon the exercise of any remedy provided for in any Leasehold Mortgage or enters into a new Ground Lease with the Ground Lessor pursuant to Section 14.4. Section 15. Ground Lease Events of Default; Ground Lease Termination. -------------------------------------------------------- Subject to Section 9.1, if any of the following events shall have occurred and be continuing and the Ground Lessor shall have given written notice thereof to the Ground Lessee and each Leasehold Mortgagee, then a "Ground Lease Event of --------------------- Default" shall exist hereunder: - ------- (a) a default by the Ground Lessee in the payment of any amounts when and as due under this Ground Lease, which default shall remain uncured for a period of ten (10) days from the date such payment is due; (b) a default by the Ground Lessee in any material respect in the performance of any of its obligations hereunder (other than as set forth in Section 9.1 or 15(a)) and such default shall have continued unremedied for more than thirty (30) days after the date of the notice of default, provided, however, that the continuation of any such default for such -------- ------- period of thirty (30) days or such longer period (not to exceed ninety (90) days) after receipt of such notice shall not constitute a Ground Lease Event of Default so long as (i) such default is curable or correctable and - (ii) the Ground Lessee is diligently pursuing the cure or correction of -- such default; or 26 (c) the Ground Lessee (or, if the Owner Participant or Termination Owner is guaranteeing the obligations of the Owner Trustee, the Owner Participant or Termination Owner, as the case may be) shall file, or consent to the filing against it of, a petition for relief or reorganization or arrangement or any other petition in bankruptcy, for liquidation or to take advantage of any bankruptcy or insolvency law of any jurisdiction or the Ground Lessee shall make an assignment for the benefit of its creditors or the Ground Lessee shall consent to the appointment of a custodian, receiver, trustee or other officer with similar powers of itself for substantially all its property, or be adjudicated insolvent or an order for relief shall be entered against the Ground Lessee in any case or proceeding for liquidation or reorganization or otherwise to take advantage of any bankruptcy or insolvency law of any jurisdiction, or ordering the dissolution, winding up or liquidation of the Ground Lessee (or the Owner Participant, as applicable) or any petition for any such relief shall be filed against the Ground Lessee and shall not be dismissed within sixty (60) days, provided, however, no such filing, consent, adjudication, order, -------- ------- or other action described above in this Section 15(c) with respect to the Owner Trustee shall constitute a Ground Lease Event of Default so long as (i) the Owner Participant is diligently pursuing the replacement of the -- Owner Trustee as permitted by the Operative Documents, (ii) no other Ground -- Lessee default shall occur under this Ground Lease and (iii) the Ground --- Lessor shall suffer no adverse effect in any material respect with respect to or in any way relating to the reorganization of the Owner Trustee or the replacement of the Owner Trustee. At any time at which a Ground Lease Event of Default has occurred and is continuing, but subject to Sections 14.2(b), 9.1 and 9.2, the Ground Lessor may (i) give a termination notice to the Ground Lessee, whereupon this - Ground Lease shall terminate and all rights of the Ground Lessee under this Ground Lease shall cease; (ii) (1) demand that the Ground Lessee, and the Ground -- - Lessee shall, return the Site promptly to the Ground Lessor as if the Site were being returned at the end of the Ground Lease Term and (2) enter upon the Site - and take immediate possession of the Site (to the exclusion of the Ground Lessee) or (iii) pursue such other remedies as may be --- 27 available to the Ground Lessor. For the avoidance of doubt, nothing in this Section 15 shall derogate from Section 9.1. Section 16. Permitted Contests. The Ground Lessee, at its expense, ------------------ and, if legally required, in the name of the Ground Lessor, may contest (after prior written notice to the Ground Lessor), by appropriate legal proceedings conducted with due diligence, the amount or validity or application, in whole or in part, of any Ground Lease Impositions or utility bill referred to in Section 18, provided that (a) neither the Site nor the Facility nor any part thereof or -------- - interest therein, nor any amounts payable to the Ground Lessor hereunder, would be in danger of being sold, forfeited or lost by reason of the pendency of such proceedings and (b) the Ground Lessor would not be in danger of any criminal - liability or, unless the Ground Lessee shall have furnished a bond or other security therefor satisfactory to the Ground Lessor, any material civil liability for failure to comply therewith during the pendency of such proceedings. The Ground Lessor will reasonably cooperate with the Ground Lessee in any such contest, at the Ground Lessee's expense unless the Ground Lessor shall derive an independent benefit from any such contest which has been a success, in which case the expenditure of the contest shall be allocated in proportion to the respective benefits derived by the Ground Lessor and the Ground Lessee, as agreed by the Ground Lessor and the Ground Lessee, or, in the absence of agreement within thirty (30) days after the request of either party for agreement on such allocation, as determined by the Appraisal Procedure. Section 17. Notices, etc. ------------ 17.1. Notices to the Leasehold Mortgagees.
