 Upon completion of the relevant commissioning tests, Contractor shall submit to the Technical Advisor to
the Bank the certificate of the results thereof for its approval or rejection. Owner and Contractor agree that the approval or rejection by the Technical Advisor to the Bank shall fully bind Owner, and that no certificate of the results of the
commissioning tests executed by the Owner’s Representative (and not by the Technical Advisor to the Bank) shall be a valid approval or rejection of such commissioning tests. 
 If the results of the test can be obtained on Site following the performance of the test and the test has been completed successfully, Technical Advisor
to the Bank and Contractor’s Representative shall execute the relevant certificate including the results achieved in the test. If the results of the test cannot be obtained on Site following the performance of the test, Contractor shall
promptly submit to Technical Advisor to the Bank the relevant certificate containing the results of such test. Technical Advisor to the Bank shall promptly review such certificate and results and shall determine whether the test has been
successfully completed within five (5) business days following receipt of such certificate. 
 If any Unit fails to complete any test,
the Technical Advisor to the Bank and Contractor’s Representative shall execute the relevant certificate including the results achieved in the relevant test for such Unit. Contractor shall repeat the test for such Unit one or several times
before the Substantial Completion Date. Contractor shall take all corrective actions so that such Unit may successfully complete the tests, without prejudice to the Owner’s rights and remedies in accordance with this Agreement. 
 Any approval or rejection of the results of the commissioning tests made by the Technical Advisor to the Bank shall always be deemed to be made by Owner
and, in the event that any Dispute regarding the commissioning tests arises, Contractor shall be entitled to settle the Dispute in accordance with Section 32. If the independent expert or the Tribunal decide that any test has been
completed successfully, such decision shall prevail and shall be binding for Owner, Contractor and the Technical Advisor to the Bank and, therefore, the relevant test shall be approved for all the purposes contemplated in this Agreement. 

4.7 Contractor shall provide to Owner a copy of the operations and maintenance manual per Park. Contractor shall provide the drafts and the final
version of the operations and maintenance manual on or before the dates contemplated in Section 4.12. Before Final Completion, Contractor shall remove debris, Equipment and surplus materials from the relevant part of Site where the Park
is located. 
 4.8 Owner shall be solely responsible to pursue and obtain any subsidies, rebates or other incentives that may be available
from any Governmental Authority pursuant to or in connection with the purchase of each Unit or otherwise, and Contractor makes no representation or warranty to Owner as to the availability of any of such incentives. Contractor shall provide Owner
reasonable assistance upon request; provided that Owner shall reimburse Contractor, upon demand by Contractor, for any expense incurred by Contractor in providing such assistance.

shall apply mutatis mutandis. 
 8. Protective Measures. 
 8.1 Contractor shall be responsible for all injury or damage to individuals or property that may occur as a result of its fault or negligence or that of its Subcontractors (other than Solarpack) in connection with the
performance of the Work. Contractor shall be responsible for the proper care and protection of all Equipment and materials furnished by Contractor and the Work performed until Final Completion of the Work for each Unit. Given that Owner is
responsible for providing the fence, gates, lighting and security infrastructure for the Park, Owner shall arrange for the adequate protection for adjacent property to the extent required by law or by this Agreement, including protection of any Work
existing in public property. 
 8.2 Contractor shall take all reasonably necessary precautions for the safety of its employees on the
relevant part of the Site where the Park is located and prevent accidents or injury to individuals on, about, or adjacent to the premises where the Work is being performed.

information and comments, although Contractor shall remain responsible for the correctness and completeness of the Health and Safety Study and its implementation through the Health and Safety Plan. 
 Contractor will adopt, maintain and supervise all measures and programs required to ensure the safety of all the persons present in the relevant part of
the Site where the Park is located. Unless otherwise agreed, Contractor shall, from the commencement of the Work on the Park until Final Completion: (i) provide proper fencing, gates, lighting, security infrastructure and warnings in the Park;
(ii) provide proper temporary roadways, footways; and (iii) take all steps to protect the environment on and off the relevant part of the Site where the Park is located and to avoid damage and nuisance to persons or to properties resulting

delay or anticipated delay in Contractor’s performance of this Agreement due to a Force Majeure Event, and the reason for and anticipated length of the delay. If reasonably feasible, Contractor shall deliver such notice within forty-eight
(48) hours of when Contractor becomes aware of such delay. Contractor shall be excused for any delays or defaults in the performance of its obligations under this Agreement that are the result of a Force Majeure Event or any other event outside
the reasonable control of Contractor. Contractor shall be entitled to a reasonable extension of time for delays due to a Force Majeure Event; provided that any Force Majeure Event that prevents performance, or is reasonably expected to
prevent performance, for more than ninety (90) days shall entitle either Party to terminate this Agreement, in which case, Section 11.4 shall apply. Any modification to the Construction and Milestone Payment Schedule pursuant to
this Section 9 shall be documented by a written Change Order to this Agreement. 
 10. Unanticipated Conditions. If any unusual or
unanticipated conditions exist or arise at the Site (such as hazardous materials, environmental conditions, pollution or archeological findings), which conditions would involve the incurrence by Contractor of any expenses to correct such conditions,
Contractor shall submit a request for approval of the corrective work and payment of the related expenses to Owner, which approval shall not be unreasonably withheld, conditioned or delayed. The additional work resulting therefrom will be paid for
by Owner as extra Work pursuant to Section 7. ***

provided, however, that independent of such warranty, Contractor shall provide Owner a performance guaranty set forth in Schedule 23(c). The letter of credit contained in Schedule 23(b) shall remain in force for a *** period,
starting from date of Substantial Completion of the first Unit of the Park, and, to the extent it is dependent upon operation and/or maintenance, is conditional on the operation and maintenance of the Work and/or the Units by or for Owner in
accordance with the operation and maintenance manuals prepared and delivered to Owner by Contractor. Contractor shall not be liable for any defect or deficiency to the extent that the same results from the specific written direction of Owner
relating to the Work and/or the Units, provided that any such defect or deficiency is not the result of Contractor’s failure to properly implement the Works in accordance with this Agreement. The scope of such warranty will include the warranty
statements provided under the warranties referenced in Section 23.2 below for claims made by Owner under such warranties during the Contractor’s *** period set forth on Schedule 23(a). Contractor’s obligations pursuant to
this paragraph shall be supported by its parent company under the comfort letter referenced in Clause 23.4. 
 23.2 Upon expiration of
the aforementioned *** period, Contractor will provide Owner with copies of pass-through warranties provided by PV module and inverter Suppliers for the benefit of Owner (the “Third Party Warranties”), which have been approved by Owner and
by the Technical Advisor to the Bank and which shall 

  

 35 
  

					
		  	 *** CONFIDENTIAL MATERIAL REDACTED AND
 SEPARATELY FILED WITH THE COMMISSION***
	  	

 
allow Owner to assign the same. Subject to this Clause 23.2, Owner shall be responsible for supervising such warranties Third Party Warranties to confirm
that they warrant (a) in the case of PV modules, a ninety percent (90%) rated power output for years three (3) through ten (10), and a minimum of eighty percent (80%) rated power from years eleven (11) through twenty five
(25) and (b) in the case of inverters, a *** from the date of expiration of the aforementioned *** period. Contractor shall include in the subcontracts for the civil works (so long as no additional expenses or liabilities are incurred by
Contractor) a provision contemplating the Contractor’s faculty to assign at no cost in favor of Owner its legal rights vis-à-vis the relevant Subcontractor under the Ley 38/1999, of November 5, de Ordenación

23.3 At Substantial Completion Date Contractor will provide a standby letter of credit representing *** of the Contract Price finally payable to
Contractor (net of any fees payable to Solarpack under the Developer Subcontract) minus the Contract Price for PV modules and inverters. The standby letter of credit will be issued by a bank chosen by Contractor (duly confirmed at Owner’s cost
by a Spanish bank), will be substantially the form of Schedule 23(b), and shall remain in force from the Substantial Completion Date and for the *** period during which the Contractor’s warranties for any each of the Units remain in
force. The standby letter of credit will secure Contractor’s warranty performance obligations and its obligations to indemnify Owner as described in Section 4.5 for any liabilities, penalties or other damages it may incur (excluding
the payment of VAT itself) as a result of its status as importer of record. 
 If the issuing bank of the letter of credit contemplated in
Schedule 23(b) decides not to permit such letter of credit to be extended beyond the *** starting from date of Substantial Completion of the first Unit of the Park, and Contractor fails to provide Owner with an acceptable extended or
substitute letter of credit at least thirty (30) days prior to expiration of such *** starting from date of Substantial Completion of the first Unit of the Park, Owner shall be entitled to draw the amounts guaranteed by the letter of credit
pursuant to the terms and conditions of Schedule 23 (b). In such event, the amounts drawn by Owner shall remain deposited in a bank account during the remaining *** of the warranty period in order to secure Contractor’s warranty performance
obligations and its obligations to indemnify Owner as described in Section 4.5 for any liabilities, penalties or other damages it may incur (excluding the payment of VAT itself) as a result of its status as importer of record. Upon expiration
of the warranty period, Owner shall immediately return to Contractor any surplus deposited in such bank account.

affiliates, and their assigns, subsidiaries, affiliates, directors, officers and employees, and of any right of the insurers to any set-off or counterclaim or any other deduction, whether by attachment or otherwise, in respect of any liability of
any such Person insured under Contractor’s Commercial General Liability policy. Contractor releases and waives any and all rights of recovery against Owner and all of its affiliates, subsidiaries, employees, successors, permitted assigns,
insurers and underwriters that Contractor may otherwise have or acquire in or from or in any way connected with any loss covered by policies of insurance maintained or required to be maintained by Contractor pursuant to this Agreement or because of
deductible clauses in or inadequacy of limits of any such policies of insurance. 
 24.4 If at any time the insurance to be provided by Owner
or Contractor hereunder shall be reduced or cease to be maintained, then (without limiting the rights of the other Party in respect of any default that arises as a result of such failure) the other Party may at its option take out and maintain the
insurance required hereby and, in such event, (a) Owner may withhold the cost of insurance premiums expent for such replacement insurance from any payments to Contractor, or (b) Owner shall reimburse Contractor for the premium of any such
replacement insurance, as applicable. 
 24.5 The insurance policies limits in no way shall be construed as limits on the Parties’
liability under this Agreement, subject to the provisions of Section 25.5.

may be affected by the risks insured. The insurance policies shall permit Owner to assign its rights thereunder to third parties at no cost. 
 24.7 Each Party shall provide the other Party with executed copies of the insurance policies contemplated in Parts I and II of Schedule 24 and with evidence that the premiums have been paid not later than thirty
(30) days following the Effective Date. Owner shall provide Contractor with executed copies of the insurance policies contemplated in Part III of Schedule 24 and with evidence that the premiums have been paid not later than
thirty (30) days following Substantial Completion of the Full Park. 
 25. Indemnity. 
 25.1 Subject to Section 24, Contractor shall fully indemnify, save harmless and defend Owner from and against any and all costs, claims, and
expenses incurred by Owner in connection with or arising from any claim by a third party for physical damage to or physical destruction of property, or death of or bodily injury to any person, but only to the extent caused by (a) the
negligence, gross negligence or willful misconduct of Contractor or its agents or employees or others under Contractor’s control or (b) a breach by Contractor of its obligations hereunder. 
 25.2 Subject to Section 24, Owner shall fully indemnify, save harmless and defend Contractor from and against any and all costs, claims, and
expenses incurred by Contractor in connection with or arising from any claim by a third party for physical damage to or physical destruction of property, or death of or bodily injury to any person, but only to the extent caused by (a) the
negligence, gross negligence or willful misconduct of Owner or any Site Lessor or their respective agents or employees or others under Owner’s or any Site Lessor’s control or (b) a breach by Owner of its obligations hereunder.

 25.3 Each Party shall indemnify, defend and hold the other Party, and its present and future direct and indirect parents, subsidiaries and
affiliates and their directors, officers, shareholders, employees, agents and representatives harmless from and against any and all claims, actions, suits, proceedings, losses, liabilities, penalties, damages, costs or expenses (including
attorneys’ fees and disbursements) of any kind whatsoever arising from (a) actual or alleged infringement or misappropriation by such Party (or in the case of Contractor, any Subcontractor and, in the case of Owner, any Site Lessor) of any
patent, copyright, trade secret, trademark, service mark, trade name, or other intellectual property right in connection with the Units, including without limitation, any deliverable, (b) such Party’s (or in the case of Contractor, any
Subcontractor’s and, in the case of Owner, any Site Lessor’s) violation of any third-party license to use intellectual property in connection with the Work, including, without limitation, any deliverable. 
 25.4 If any claim is brought against a Party (the “Indemnifying Party”), then the other Party (the “Indemnified Party”)
shall be entitled to participate in, and, unless in the opinion of counsel for the Indemnifying Party a conflict of interest between the Parties may exist with respect to such claim, assume the defense of such claim, with counsel 

  

 38 
  

					
		  	 *** CONFIDENTIAL MATERIAL REDACTED AND
 SEPARATELY FILED WITH THE COMMISSION***
	  	

 
reasonably acceptable to the Indemnifying Party. If the Indemnified Party does not assume the defense of the Indemnifying Party, or if a conflict precludes
the Indemnified Party from assuming the defense, then the Indemnified Party shall reimburse the Indemnifying Party on a monthly basis for the Indemnifying Party’s defense through separate counsel of the Indemnifying Party’s choice. Even if
the Indemnified Party assumes the defense of the Indemnifying Party with acceptable counsel, the Indemnifying Party, at its sole option, may participate in the defense, at its own expense, with counsel of its own choice without relieving the
Indemnified Party of any of its obligations hereunder. 
 25.5 IN NO EVENT SHALL THE INDEMNIFYING PARTY BE LIABLE TO THE INDEMNIFIED PARTY
FOR INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF OR RELATED TO THE TERMS OF THIS AGREEMENT, INCLUDING BUT NOT LIMITED TO LOST PROFITS, COSTS OF PROCUREMENT OF SUBSTITUTE GOODS OR SERVICES OR BUSINESS INTERRUPTION, EVEN IF THE
INDEMNIFYING PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES, BUT EXCEPT FOR LOSS OR DAMAGE ARISING OUT OF THE PARTIES’ WILLFUL MISCONDUCT OR GROSS NEGLIGENCE. IN ADDITION, WHETHER AN ACTION OR CLAIM IS BASED ON WARRANTY, CONTRACT,
TORT OR OTHERWISE, UNDER NO CIRCUMSTANCE SHALL THE INDEMNIFYING PARTY’S TOTAL LIABILITY ARISING OUT OF OR RELATED TO THIS AGREEMENT EXCEED THE TOTAL AMOUNT PAID BY OWNER TO CONTRACTOR HEREUNDER, MINUS THE AGGREGATE AMOUNT OF ANY PENALTIES PAID
BY THE INDEMNIFYING PARTY UNDER THIS AGREEMENT. 
 25.6 The Parties also agree that any proceeds collected by the Indemnified Party as
beneficiary of any of the insurance policies contemplated in Schedule 24 shall be deducted from the corresponding claim for damages. Moreover, in the event that the proceeds collected by the Indemnified Party as beneficiary of an
insurance policy completely indemnify (“mantienen indemne”) such Party from all damages and expenses incurred, the Indemnified Party shall not be entitled to claim any amount as damages and expenses, and shall be obliged, if
applicable, to return to the Indemnifying Party any surplus received. Any franchises, deductibles, caps of liability and any other deductions which may affect the compensations to be paid by the insurance companies to the Indemnified Party shall not
be deducted from the indemnification due. 
 26. Performance of the Work. 
 26.1 Contractor agrees to use, and agrees that it shall require each of its Subcontractors to use, only personnel who are qualified and properly trained

 27.2 In the event of change of any Applicable Law between the date of execution of this Agreement and the Substantial Completion Date, the

 31. Nonwaiver. The failure of either Party to insist upon or
enforce, in any instance, strict performance by the other Party of any of the terms of this Agreement or to exercise any rights herein conferred shall not be construed as a waiver or relinquishment to any extent of its right to assert, or rely upon
any such terms or rights on any future occasion. No waiver shall be valid unless stated in writing as set forth in Section 33. 
 32. Dispute

 32.1 Good faith negotiations. In the event that any question, dispute, difference or claim arises
out or is in connection with this Agreement, including any question regarding its existence, validity, performance or termination (a “Dispute”), which either Party has notified to the other, senior management personnel from both
Contractor and Owner shall meet and diligently attempt in good faith to resolve the Dispute for a period of thirty (30) days following one Party’s written request to the other Party for such a meeting. If, however, either Party refuses or
fails to so meet, or the Dispute is not resolved by negotiation, the provisions of Sections 32.2 and 32.3 shall apply. 
 32.2
Technical Dispute. Technical Disputes shall be resolved by an independent expert. For the purposes of this Agreement, a “Technical Dispute” shall mean a Dispute regarding whether the Park conforms to the Technical

 32.3 Arbitration. Any Dispute
which cannot be settled by negotiation pursuant to Section 31.1 above or which is not a Technical Dispute, shall be exclusively referred to and finally resolved by arbitration at law (arbitraje de derecho). The Parties expressly
waive their right to any form of legal recourse and submit all disputes arising out of or in connection with this Agreement to arbitration, in accordance with the conditions laid down in this Clause 32.3. For illustrative purposes only, a Dispute
submitted to arbitration means any kind of point, claim, dispute or controversy that constitute a difference between the Parties and that they are unable or unwilling to settle by themselves by negotiation pursuant to Section 31.1 above,
whether relating to the performance and completion of the Agreement, interpretation, execution, rights and obligations arising out of the Agreement, bilateral services and their execution, or breach, inefficacy, defects and consequences, invalidity
or avoidance, termination or cancellation. 
  

 42 
  

					
		  	 *** CONFIDENTIAL MATERIAL REDACTED AND
 SEPARATELY FILED WITH THE COMMISSION***
	  	

 Arbitration of law shall be applied under the Rules of Arbitration of the Civil and Mercantile Court of
Arbitration (CIMA). The Parties submit to the Rules of Procedure of the Court and its Tariffs (the “Rules”), acknowledging that they are apprised of them and herein undertake to act in good faith during the proceedings at all times
and comply with the rulings and arbitral awards, without prejudice to any legal appeals to which they are entitled. Consequently, they undertake to cooperate with the arbitral proceedings in all ways, to establish the exact nature of the difference
and to determine whether it is national or international. The Parties also bind themselves to submit any documentation and evidence that may be required from them at any given moment during the course of proceedings, and to pay the advance of costs,
fees, expenses and other costs apportioned by the Court without delay. 
 An arbitral tribunal (the “Tribunal”) composed of
three arbitrators shall be nominated from among the members of the Civil and Mercantile Court of Arbitration to hear and rule on disputes. The third arbitrator shall preside over the Tribunal and shall be designated by the Court President, in
accordance with Court Statutes, which the Parties are apprised of. The remaining two arbitrators shall be nominated by the Parties when the difference arises, one (1) appointed by each Party. Arbitrators shall be fluent in English. In the event
of an arbitrator repudiating or rejecting the appointment or the occurrence of any other circumstances that prevent him from acting, a substitute arbitrator shall be nominated by the person or persons who nominated the original arbitrator. If this
has not been effected fifteen (15) calendar days after one Party notified the other Party, the arbitrator shall be appointed by the Court President. 
 The seat of the arbitration shall be Madrid. The arbitration shall be conducted in English. All documents submitted in connection with the arbitration proceedings shall be in the English language or, if in another
language, accompanied by an English translation. 
 The Tribunal shall be entitled to appoint any independent expert (either architect or
engineer) to render its opinion on (i) the cause or origin of the relevant damages or defects, and (ii) the Party which is responsible for such damages or defects. The Tribunal shall be entitled to impose to the defaulting Party in the
relevant award the performance of any corrective action or the payment of any compensation that shall be determined in accordance with Section 11 and Section 25 hereof. The Tribunal shall issue the award within six
(6) months following the date of acceptance of the last of the arbitrators to act as arbitrator. Both Parties undertake to implement the arbitration award, which shall be final and binding. Any award issued by the Tribunal shall include
interest from the date of the award until paid in full, at the rate of Euribor plus two percent (2%). 
 32.4 Arbitrator Confidentiality
Obligation The Parties shall ensure that any arbitrator appointed to act under this Section will agree to be bound to the provisions of Section 34 with respect to the terms of this Agreement and any information obtained during the
course of the arbitration proceedings. 
 32.5 The obligation to arbitrate described in this Section 32 shall not apply with
respect to requests for preliminary injunctions, temporary restraining orders, specific 

  

 43 
  

					
		  	 *** CONFIDENTIAL MATERIAL REDACTED AND

performance, or other procedures in a court of competent jurisdiction to obtain interim relief when deemed necessary by such court to preserve the status quo
or prevent irreparable injury pending resolution by arbitration of the actual Dispute. 
 32.6 The parties agree to submit to the tribunals
of Madrid for any question which can not be submitted to arbitration, including provisional measures, and for the execution of the obtained award. 
 33.
Notices and Demands. Any notice, request, demand or other communication required or permitted under this Agreement, shall be deemed to be properly given by the sender and received by the addressee if made in writing and (a) if personally
delivered; (b) three (3) days after deposit in the mail if mailed by certified or registered air mail, post prepaid, with a return receipt requested; or (c) if sent by facsimile with confirmation. Mailed notices and facsimile notices

that the Disclosing Party may determine whether to take steps to oppose such disclosure. This provision shall survive the termination of this Agreement for a ten (10) year period. 
 35. Time of Essence. Time is expressly agreed to be of the essence of this Agreement and each, every and all of the terms, conditions and provisions herein.

 c. no later than the second business day following the date on which all of the
conditions set forth in the foregoing clauses a. and b. have been satisfied, the Transferee shall arrange for the Company to make, and the Company shall make, a payment in an amount equal to *** less the amount received by the Transferee pursuant to
Section 5.2.5 of the Agreement (as amended hereby). All subsequent payments of the Contract Price shall be made in accordance with the EPC Contract, as amended by this letter. For the avoidance of doubt, the payment corresponding to the
month of April in the Schedule of Values (as defined in the EPC Contract) shall be payable within 15 days after invoice by the Transferor, which invoice shall not be submitted by the Transferor prior to the date on which the conditions set forth in
Sections 2.a and 2.b of this letter are satisfied. 
 3. Amendments to Order of Closing. Subject to
Section 1, and acknowledging the provisions of Section 2, of this letter, Section 7.2.1(b), Section 7.2.2(b), Section 7.2.3(d) and Section 7.2.5 of the Agreement are hereby amended to
exclude therefrom the delivery or issuance of those items set forth therein that have been expressly waived as Conditions by the provisions of Section 1 of this letter. 
 4. Reconveyance. If the conditions set forth in Section 2(a) of this letter are not satisfied on or prior to April 20, 2007, the
Parties shall negotiate in good faith with a view to modifying the terms of the transaction contemplated by the Agreement in a manner mutually acceptable to the Parties; provided, however, if the Parties are unable to reach agreement
as to the modification of such terms by ***, then the Parties shall unwind the Agreement, the result of which will require the Parties, within 2 Business Days thereafter (such date being, the “Reconveyance Date”), to execute
such instruments, agreements and other documents as are necessary to effect the transfer and reconveyance of the Units to, and the vesting of ownership of the Units in, the Transferor free and clear of all material liabilities (contingent or
otherwise) and encumbrances other than those existing under the Project Documents on the Closing Date. Such reconveyance instruments shall require: (i) return of all payments made by Transferee (or through Company) to Transferor under the
Agreement or EPC Contract, plus interest accruing daily at the lesser of a rate of 13% per annum and the maximum rate permitted by applicable law; (ii) delivery by the Transferor of a letter of credit in favor of NPC to replace the
Replacement LC or confirmation by the Transferor that the letter of credit delivered to NPC and in effect on the date hereof remains in effect and has not been returned by NPC; and (iii) and that Transferor shall hold harmless and indemnify
Transferee for all liabilities and obligations of Solar Star pursuant to the Project Documents that may arise due to its brief ownership of the Units, except for those liabilities that arise from Transferee’s willful misconduct or negligence
during the period in which it owns the Units. In furtherance of the foregoing, the Transferee agrees that it (a) shall cause the Company not to incur any material liabilities (contingent or otherwise), indebtedness, liens or encumbrances on the
Company’s assets (other than as required by the Project Documents), (b) shall not transfer any of the Units until the earlier to occur of (1) the date on which all of the conditions set forth in Section 2 of this letter
are satisfied and (2) the Reconveyance Date and (c) shall not breach any Project Document to which it is a party.

modified to the extent necessary to take into account the waivers set forth in this letter. 
 6. Continuing Covenants.
Notwithstanding Section 6.5 of the Agreement, to the extent still applicable, the covenants set forth in Sections 6.1, 6.3, and 6.4 of the Agreement shall continue to bind the Parties through April 20, 2007,
after which date such covenants shall be of no further force and effect. 
 7. Expenses. If the Reconveyance Date occurs, the
Transferor agrees to reimburse the Transferee for all reasonable, documented out-of-pocket expenses incurred by the Transferee from and after the Closing Date until the Reconveyance Date in furtherance of the agreements and undertakings set forth in

the Parties irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such court. Each of the Parties agrees that a final judgment in any such action or proceeding shall be
conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this letter shall affect any right that any Party may otherwise have to bring any action or proceeding relating to this
letter in the courts of any jurisdiction. 
 d. Each Party irrevocably and unconditionally waives, to the fullest extent
permitted by applicable law, any objection that it may now or hereafter have to the laying of venue of any action or proceeding arising out of or relating to this letter in any court referred to above. Each of the Parties hereby irrevocably waives,
to the fullest extent permitted by applicable law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.
