The Purchase Agreement Fee shall not be deemed to be a liquidated damages payment for any breach by Purchaser of this Agreement.

1.6 Purchase Price Adjustment.

(a) The Purchase Price payable on the Closing Date shall be adjusted as contemplated by Section 1.4(c) as follows:

(i) upward by an amount, if any, equal to the total combined amount of capital contributions (other than a capital contribution contemplated by Section 7.1(e)) made by HCE to HCE-Rockfort or from HCO-Jamaica to PPO from December 31, 2006 until the Closing Date; and

(ii) downward by an amount, if any, equal to the total combined amount of dividends or distributions received by HCE from HCE-Rockfort and by HCO-Jamaica from PPO (for the avoidance of doubt, excluding any payments made under any Operating Contract in the ordinary course of business) from December 31, 2006 until the Closing Date;

with the Purchase Price, plus any upward adjustment provided for in clause (i) above, and minus any downward adjustment provided for in clause (ii) above, calculated on a daily basis, accruing interest payable to Sellers at the Specified Rate for the period of time beginning on January 1, 2007 and ending on the Closing Date (the “PP Adjustment Amount”).

(b) After the Closing Date, Purchaser shall afford, and shall exercise the voting, governance and contractual powers available to it to cause, to the extent possible, the Power Company to afford, to Sellers and any accountants, counsel or financial advisers retained by Sellers in connection with any adjustment to the Closing Purchase Price contemplated by this Section 1.6 reasonable access to the books, records and employees of HCE-Rockfort, PPO and the Power Company as is reasonably requested by Sellers in connection with the matters addressed in this Section 1.6. Within forty-five (45) days after the Closing Date, Sellers shall prepare and deliver to Purchaser a notice (the “Post-Closing PP Adjustment Notice”) setting forth the proposed final PP Adjustment Amount calculated as of the Closing Date (the “Post-Closing PP Adjustment Amount”).

(c) Purchaser may dispute any amounts reflected in the Post-Closing PP Adjustment Notice; provided, however, that Purchaser shall have notified Sellers in writing of each item Purchaser is disputing in good faith, specifying the estimated amount thereof in dispute, if known or determinable, and setting forth, in reasonable detail, the basis for such dispute by no later than the tenth (10^th) Business Day following Purchaser’s receipt of the Post-Closing PP Adjustment Notice (the “Objection Notice”). If, within such period after such tenth Business Day, Purchaser shall not have given Sellers an Objection Notice with respect to the Post-Closing PP Adjustment Notice, then Purchaser shall be deemed to have accepted such notices and amounts contained therein as final and binding without amendment or modification and conclusive upon each of the Parties.

(d) If Purchaser delivers an Objection Notice, then the items in dispute shall be promptly submitted by Purchaser (in any event, no later than three (3) Business Days upon receipt by Sellers of such Objection Notice) to a mutually agreeable accounting firm (and failing agreement, one of the “Big 4” accounting firms to be determined by lot) (the “Accounting Firm”), which shall, acting as experts in accounting and not as arbitrators or legal experts, resolve those disagreements set forth in the Objection Notice. Purchaser and Sellers shall make readily available to the Accounting Firm all relevant books and records and any work papers, and all other items reasonably requested by the Accounting Firm. The fees and disbursements of the Accounting Firm shall be borne equally by Purchaser and HCE. Within twenty (20) Business Days after such submission, the Accounting Firm shall, and the Parties shall direct the Accounting Firm to, determine and report to Purchaser and Sellers upon such disputed items, and such report shall be final, binding and conclusive on the Parties. Upon completion of the foregoing procedures, the “Final PP Adjustment Amount” shall be deemed to be (i) the Post-Closing PP Adjustment Amount if Purchaser shall not have objected thereto within the specified time period set forth in Section 1.6(c) or (ii) as determined or reported by the Accounting Firm in accordance with this Section 1.6(d).

(e) Within three (3) Business Days following completion of the foregoing procedures in Section 1.6(d):

(i) if the Final PP Adjustment Amount exceeds the PP Adjustment Amount, then Purchaser shall pay to HCE an amount equal to the difference between the Final PP Adjustment Amount and the PP Adjustment Amount;

(ii) if the Final PP Adjustment Amount is less than the PP Adjustment Amount, then HCE shall pay to Purchaser an amount equal to the difference between the Final PP Adjustment Amount and the PP Adjustment Amount; or

(iii) if the Final PP Adjustment Amount is equal to the PP Adjustment Amount, then there shall be no further payment under this Section 1.6(e).

Any payment made pursuant to the foregoing clauses (i)-(ii) shall be made by wire transfer of immediately available funds in United States dollars in accordance with wire instructions delivered by Sellers or Purchaser, as the case may be, to the other Party. To the extent any payment required to be made under this Section 1.6(e) is not made by such third (3^rd) Business Day, the amount payable will bear interest from such third (3^rd) Business Day at the Specified Rate.

Nothing contained herein shall be construed as requiring Parent, Purchaser, HCE-Rockfort or any Jamaica Subsidiary to continue or to cause the continuance of any specific employee benefit plans or to continue or cause the continuance of the employment of any specific person.

(b) With respect to each benefit plan of Parent, Purchaser or any of its respective Subsidiaries in which a Continuing Employee participates after the Closing, for purposes of determining eligibility, vesting and amount of benefits, including severance benefits and paid time off entitlement (but not for pension benefit accrual purposes), Purchaser shall cause service with HCE-Rockfort and the Jamaica Subsidiaries (or predecessor employers to the extent HCE-Rockfort or any Jamaica Subsidiary provided past service credit) to be treated as service with Parent, Purchaser and their respective Subsidiaries; provided that such service shall not be recognized to the extent that such recognition would result in a duplication of benefits or to the extent that such service was not recognized under an analogous Companies Plan.

In the event of any such Action, Purchaser shall cooperate with the Indemnified Person in the defense of any such Action.

(b) Survival of Indemnification. To the fullest extent not prohibited by Law, from and after the Closing Date, all rights to indemnification now existing in favor of the Indemnified Persons with respect to their activities as such prior to, on or after the Closing Date, as provided in HCE-Rockfort’s and each Jamaica Subsidiary’s respective Organizational Documents or indemnification agreements in effect on the date of such activities or otherwise in effect on the date hereof, shall survive the Closing and shall continue in full force and effect for a period of not less than four (4) years from the Closing Date, provided that, in the event any claim or claims are asserted or made within such survival period, all such rights to indemnification in respect of any claim or claims shall continue until final disposition of such claim or claims.

Purchaser and Sellers agree to use reasonable efforts to refrain from taking any action which could reasonably be expected to materially delay the consummation of the Transactions.

5.11 Supplements to Disclosure Letters. Sellers may, from time to time prior to the Closing by written notice to Purchaser, supplement the Sellers Disclosure Letter or the Companies Disclosure Letter or add a schedule or section to the Sellers Disclosure Letter or the Companies Disclosure Letter with a corresponding reference to be added in this Agreement (such added schedule to be deemed a supplement hereunder) to disclose any matter which, if occurring prior to the date hereof, would have been required to be set forth or described on the Sellers Disclosure Letter or the Companies Disclosure Letter or to correct any inaccuracy or breach in the representations and warranties made by Sellers in this Agreement. Subject to this Section 5.11, none of such supplements to the Sellers Disclosure Letter or the Companies Disclosure Letter shall be deemed to cure any breach or breaches of the representations and warranties to which such matters relate with respect to satisfaction of the conditions set forth in Section 6.2(b) or otherwise affect any other term or condition contained in this Agreement; provided, however, that unless Purchaser shall have delivered a Breach Notice contemplated by Section 7.1(e) (to the extent Purchaser is entitled to deliver such Breach Notice pursuant to the terms of this Agreement) within ten (10) Business Days of the receipt by Purchaser of any supplement to the Sellers Disclosure Letter or the Companies Disclosure Letter pursuant to this Section 5.11, then Purchaser shall have waived any and all rights to terminate this Agreement, pursuant to Section 7.1(e) or otherwise, arising out of or relating to the contents of such supplement and the resulting breach or breaches of the representations and warranties and Purchaser shall be deemed to have accepted the contents of such supplement for all purposes of this Agreement; provided, further, that, from and after the Closing, Sellers shall have no liability pursuant to this Agreement or for any matters arising out of or relating to any of the matters disclosed on the Sellers Disclosure Letter or the Companies Disclosure Letter, as supplemented or amended by Sellers, prior to the Closing.

(b) The Parties acknowledge that any damage caused to Sellers or any of its respective Affiliates by reason of the breach by Purchaser or any of its Affiliates of Section 5.12(a), in each case would cause irreparable harm that could not be adequately compensated for in monetary damages alone; therefore, each Party agrees that, in addition to any other remedies, at law or otherwise; Sellers and any of their respective Affiliates shall be entitled to an injunction issued by a court of competent jurisdiction restraining and enjoining any violation by Purchaser or any of its Affiliates of Section 5.12(a), and Purchaser further agrees that it (x) will stipulate to the fact that Sellers or any of their respective Affiliates, as applicable, have been irreparably harmed by such violation and not oppose the granting of such injunctive relief and (y) waive any requirement that Sellers post any bond or similar requirement in order for Sellers to obtain the injunctive relief contemplated by this Section 5.12(b).

Tax Matters

	1.		The statute of limitations for the U.S. federal income tax returns for HCE-Rockfort with respect to the 1992 to 2001 taxable years has been extended through December 31, 2007 and the statute of limitations for the U.S. federal income tax returns prepared for HCE-Rockfort with respect to the 2002 to 2004 taxable years has been extended through December 31, 2008.

	2.		Pursuant to the Implementation Agreement between the Government of Jamaica and the Power Company dated October 10, 1994, the Power Company was exempted from liability for taxes on income in Jamaica for a period of seven years from that date.

	3.		Pursuant to the Implementation Agreement between the Government of Jamaica and the Power Company dated October 10, 1994, the Power Company was entitled to import and export certain items of plant and machinery without payment of customs duty, stamp duties or general consumption tax.

	4.		With the exception of the Pollution Liability insurance policy, the Power Company has utilized insurance brokers located in the USA and insurance companies located off the island of Jamaica for certain insurance policies. Pollution Liability insurance policy was issued by an insurer in Jamaica. General Consumption Tax is chargeable in respect of services rendered locally as well as imported services. Except, however for the payment of General Consumption Tax in respect of the Pollution Liability insurance policy in 2005 and 2006, no General Consumption Tax has been paid in respect of the insurance policies. In addition, the Insurance Regulations (Jamaica) provides for the payment of a surcharge on any insurance placed in a country other than Jamaica. No surcharge has been paid by the Power Company based on advice received from Price Waterhouse Coopers that the Insurance Act only regulates insurance companies, brokers and agents and any other person governed by the Act. Since the Power Company does not fall under the scope of people governed by the Act and there is no mechanism in place to enforce the surcharge against persons who do not fall within the ambit of the Insurance law, the advice received was that the Power Company would have no tax liability in this regard.
