At the Effective Time, (a) the directors of Buyer immediately prior to the Effective Time shall be the initial directors of Buyer, as the surviving corporation, each to hold office in accordance with the Organizational Documents of Buyer; and (b) the officers of Buyer immediately prior to the Effective Time shall be the initial officers of Buyer, as the surviving corporation, in each case until their respective successors are duly elected or appointed.

2.5 CONVERSION OF SECURITIES; DISSENTING SHARES

(a) Subject to subsection (d) regarding fractional shares, at the Effective Time, by virtue of the NorthStar Merger and without action on the part of Buyer or NorthStar, each Share issued and outstanding immediately prior to the Effective Time, other than (i) Shares held in the treasury of NorthStar, and (ii) Dissenting Shares, shall cease to be outstanding and shall be converted into the right to receive the Consideration, subject to the Escrow Agreement with respect to the Escrow.

(b) Each Share held by NorthStar as treasury stock immediately prior to the Effective Time shall be canceled and extinguished without any conversion thereof as provided in this Section 2.5.

(c) The “Consideration” shall be (i) for each Share held by stockholders owning beneficially less than 1,000 Shares, an amount in cash equal to the Per Share Consideration, or (ii) for each Share held by stockholders owning beneficially 1,000 or more Shares, (A) an amount in cash equal to twenty percent (20%) of the Per Share Consideration (the “Cash Amount”), plus (B) a number of shares of Buyer’s common stock, $0.01par value, using the Closing Price equal to eighty percent (80%) of the Per Share Consideration (the “Stock Amount”). Notwithstanding the foregoing, the parties acknowledge and agree that, subject to the requirements of subsection 2.5(f), the Buyer may elect to increase the Cash Amount and reduce the Stock Amount in the event that the Closing Price is less than $20.80. The shares included in the Stock Amount will not be registered with the SEC under the Securities Act or under any state securities laws, in reliance on the exemptions specified in such laws, and have not been approved or disapproved by the SEC, or by the securities regulatory authority of any state. Such shares included in the Stock Amount will be subject to Section 2.6 regarding Buyer’s right of first refusal and to restrictions on resale and may not be sold or otherwise transferred without compliance with those rights and restrictions.

(d) No fractional shares of capital stock of Buyer shall be issued in the NorthStar Merger. In lieu of a fractional share of Buyer common stock, the holder of any Shares who would otherwise be entitled to receive such fractional share (after taking into account all Shares delivered by such holder) shall be entitled to receive a cash payment, without interest and rounded-up to the nearest whole cent, in an amount determined by multiplying the Closing Price by the fraction of a share of Buyer common stock to which the holder would otherwise have been entitled. As promptly as practicable after the determination of the amount of cash, if any, to be paid to holders of fractional share interests, the bank or trust company designated by Buyer as the exchange agent (the “Exchange Agent”) shall so notify Buyer, and Buyer shall deposit that amount with the Exchange Agent and shall cause the Exchange Agent to forward payments to the holders of fractional share interests, subject to and in accordance with the terms of this Section 2.5.

(e) Notwithstanding anything in this Agreement to the contrary, Shares which are issued and outstanding immediately prior to the Effective Time and which are held by NorthStar stockholders who have validly exercised dissenter’s rights available under Section 351.455 of the GBCLM (the “Dissenting Shares”) shall not be converted into or be exchangeable for the right to receive the Consideration in accordance with this Section 2.5, unless and until such holders shall have failed to perfect or shall have effectively withdrawn or lost their dissenter’s rights under the GBCLM. Dissenting Shares shall be treated in accordance with Section 351.455 of the GBCLM, if and to the extent applicable. If any such holder shall have failed to perfect or shall have effectively withdrawn or lost such dissenter’s rights, such holder’s Shares shall thereupon be converted into and become exchangeable only for the right to receive, as of the Effective Time, the Consideration in accordance with this Section 2.5. NorthStar shall give Buyer (i) prompt notice of each and every notice of a NorthStar stockholder’s intent to demand payment for the stockholder’s Shares, attempted withdrawals of such demands, and any other instruments served pursuant to the GBCLM and received by NorthStar relating to rights to be paid the “fair value” of Dissenting Shares, as provided in Section 351.455 of the GBCLM, and (ii) the opportunity to direct all negotiations and Proceedings with respect to demands for appraisal under the GBCLM. Except with the prior written consent of Buyer, NorthStar shall not voluntarily make any payment with respect to, offer to settle or settle, or approve any withdrawal of any demands for “fair value” under Section 351.455 of the GBCLM.

(f) If the tax opinion referred to in Section 7.2(d)(i) cannot be rendered because NorthStar’s counsel or accountants reasonably determine that the NorthStar Merger may not satisfy the continuity of interest requirements under applicable federal income tax principles relating to reorganizations under Section 368(a) of the IRC, then Buyer shall reduce the Cash Amount and correspondingly increase the Stock Amount to the minimum extent necessary to enable the relevant tax opinion to be rendered; provided that the Consideration, as calculated and determined pursuant to this Section 2.5, is the same.

2.6 BUYER RIGHT OF FIRST REFUSAL

(a) Prior to the second anniversary of the Closing Date, if any stockholder desires to transfer any shares of Buyer stock acquired in the NorthStar Merger to a third party pursuant to a transaction negotiated between such stockholder and third party, such stockholder shall first offer such shares to Buyer pursuant to this Section 2.6 (the “Right of First Refusal”).

Notwithstanding the provisions of this Section 2.6, until fifteen months after the Closing Date, Buyer will not purchase any shares of Buyer common stock issued to stockholders in the NorthStar Merger pursuant to this Section 2.6(a) or otherwise if the aggregate number of shares of Buyer common stock so purchased would exceed 350,000 plus sixty percent (60%) of the number of shares of Buyer common stock released to former NorthStar stockholders from the Escrow (the “Maximum Number”). If Buyer purchases the Maximum Number, it will provide the Seller Representative with prompt written notice of such event. Upon receipt of such notice, until the earlier of the date that is fifteen months after the Closing Date or the date that the Maximum Number increases above the number of shares purchased by Buyer, Buyer shall have no Right of First Refusal and no stockholder shall be required to provide a Proposed Transfer Notice with respect to such shares.

(b) Such proposed seller shall give written notice to Buyer stating such stockholder’s desire to transfer such shares, the number of shares proposed to be transferred, the exact name in which such shares are held of record, the address of such stockholder, and the price for such shares negotiated by the proposed seller and the third party (the “Proposed Transfer Notice”). Each such Proposed Transfer Notice shall be deemed to have been duly given when actually received by one of the representatives of Buyer set forth below and shall be sent to the appropriate address and telecopier numbers set forth below (or to such other address and telecopier numbers as Buyer may designate by notice to Seller Representative):

	Enterprise Bank & Trust
	▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇
	▇▇. ▇▇▇▇▇, ▇▇▇▇▇▇▇▇ ▇▇▇▇▇-▇▇▇▇
	Attention: ▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇▇ and ▇▇▇▇▇ ▇▇▇▇▇▇
	Facsimile No.: ▇▇▇-▇▇▇-▇▇▇▇, ▇▇▇-▇▇▇-▇▇▇▇ and ▇▇▇-▇▇▇-▇▇▇▇

(c) Buyer shall have fourteen (14) days from its receipt of the Proposed Transfer Notice to give the proposed seller written notice of its election to purchase such shares at a per share price equal to the per share price of Buyer common stock, as quoted on Nasdaq, for the last trading day immediately preceding the date Buyer received the Proposed Transfer Notice (the “Election Notice”).

(d) The closing of any such purchase by Buyer shall take place at the executive offices of Buyer at 10:00 a.m. local time on the date specified in the Election Notice, which shall not be more than thirty (30) days after the date of the Election Notice, or at such other time and place as the parties to the transaction may agree. At the closing, the proposed seller will deliver to Buyer certificates evidencing the shares to be purchased (properly endorsed or accompanied by stock powers, with signature guaranteed or similar appropriate documentation of authority to transfer). Buyer shall pay the purchase price stated in the Election Notice in cash or immediately available funds. In the event that the holder of the shares to be purchased by Buyer does not deliver such certificates with the required endorsement or stock powers to Buyer, as required by this subsection (d), such shares shall be deemed assigned and transferred to Buyer upon delivery of the purchase price, and Buyer’s transfer agent shall be authorized to record that the certificates have been acquired by Buyer.

(e) If Buyer does not provide the Election Notice within fourteen (14) days after its receipt of the Proposed Transfer Notice, Buyer shall be deemed to have elected not to purchase the shares identified in the Proposed Transfer Notice, and the proposed seller may transfer such shares to a third party in accordance with the Proposed Transfer Notice for a period ending forty-four (44) days after the date of receipt by Buyer of the Proposed Transfer Notice; provided that such sale is made pursuant to an exemption from registration under the Securities Act and applicable state securities laws.

(f) If (i) the stockholder is required to provide a Proposed Transfer Notice under Sections 2.6(a) and (b), and Buyer does not waive its right to purchase such shares within one Business Day after its receipt of the Proposed Transfer Notice, (ii) Buyer does not provide the Election Notice within fourteen (14) days after its receipt of the Proposed Transfer Notice, and (iii) the proposed seller transfers such shares in accordance with the Proposed Transfer Notice and the preceding sentence, Buyer shall pay such proposed seller an amount equal to (A) the Loss Amount (if any) multiplied by (B) the number of shares of Buyer stock designated in the Proposed Transfer Notice, in cash or immediately available funds within five (5) Business Days after the proposed seller notifies Buyer that the transfer has closed.

2.7 EXCHANGE OF CERTIFICATES

(a) Exchange Agent. Buyer shall deposit, or shall cause to be deposited, the Consideration (net of the Escrow and the aggregate Option Consideration) on or before the Closing Date, with the Exchange Agent, for the benefit of the holders of Shares, for exchange in accordance with this Section 2.7, through the Exchange Agent, and shall deposit, or shall cause to be deposited, from time to time, with the Exchange Agent, any dividends or distributions with respect thereto promptly following the declaration and payment thereof, if any, to be paid and issued in exchange for Shares pursuant to this Section 2.7 (the “Exchange Fund”).

(b) Exchange Procedures.

	(i) As soon as reasonably practicable after the Effective Time but in any event no more than ten (10) Business Days thereafter, the Exchange Agent shall mail to each holder of record of a certificate representing ownership of Shares (a “Certificate” or “Certificates”) whose Shares were converted into the right to receive the Consideration pursuant to Section 2.5, (A) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Exchange Agent and shall be in such form and have such other provisions as Buyer may reasonably specify) and (B) instructions for effecting the surrender of the Certificates in exchange for the Consideration.

	(ii) Upon surrender of a Certificate for cancellation to the Exchange Agent, together with such letter of transmittal, duly executed, the holder of such Certificate shall be entitled to receive in exchange therefor the Consideration and any unpaid dividends and distributions thereon as provided in this Section 2.7, which such holder has the right to receive in respect of the Certificate surrendered pursuant to the provisions of this Section 2.7 (after taking into account all Shares then held by such holder), and the Certificate so surrendered shall forthwith be canceled.

	(iii) In the event of a transfer of ownership of Shares which is not registered in the transfer records of NorthStar, a transferee may exchange the Certificate representing such Shares for the Consideration and any unpaid dividends and distributions thereon as provided in this Section 2.7 if the Certificate representing such Shares is presented to the Exchange Agent, accompanied by all documents required to evidence and effect such transfer, and by evidence that any applicable stock transfer taxes have been paid.

	(iv) In the event any Certificate shall have been lost, stolen, or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen, or destroyed and the posting by such Person of a bond in such amount as Buyer may direct as indemnity against any claim that may be made against it or the Exchange Agent with respect to such Certificate, the Exchange Agent will pay and issue in exchange for such lost, stolen, or destroyed Certificate the Consideration and any unpaid dividends and distributions thereon as provided in this Section 2.7, which such holder would have had the right to receive in respect of such lost, stolen, or destroyed Certificate.

	(v) Until surrendered as contemplated by this Section 2.7, each Certificate (other than Certificates representing Dissenting Shares) shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the Consideration and any unpaid dividends and distributions thereon as provided in this Section 2.7, subject to the Escrow Agreement with respect to the Escrow. No interest shall be paid on the Consideration.

(c) Dividends and Distributions with Respect to Unexchanged Shares. No dividends or other distributions declared or made after the Effective Time with respect to Buyer common stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Certificate with respect to the shares of Buyer common stock represented thereby, and no cash payment in lieu of fractional shares shall be paid to any such holder pursuant to Section 2.5(d), until the holder of such Certificate shall surrender such Certificate. Subject to the effect of applicable Legal Requirements, following surrender of any such Certificate, there shall be paid to the holder of the certificates representing whole shares of Buyer common stock issued in exchange therefor, without interest, (i) promptly, the amount of any cash payable with respect to a fractional share of Buyer common stock to which such holder is entitled pursuant to Section 2.5(d) and the amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such whole shares of Buyer common stock, and (ii) at the appropriate payment date, the amount of dividends or other distributions, with a record date after the Effective Time but prior to surrender and a payment date occurring after surrender, payable with respect to such whole shares of Buyer common stock.

(d) No Further Rights in the Shares. The Consideration issued and paid upon conversion of the Shares (including the payment of the Escrow to the Escrow Agent) in accordance with the terms hereof shall be deemed to have been issued and paid in full satisfaction of all rights pertaining to such Shares.

(e) Termination of Exchange Fund. Any portion of the Exchange Fund which remains undistributed to the former stockholders of NorthStar for six (6) months after the Effective Time shall be delivered to Buyer, upon demand, and any former stockholders of NorthStar who have not theretofore complied with this Section 2.7 shall thereafter look only to Buyer to claim the Consideration, any cash in lieu of fractional shares of Buyer common stock, and any dividends or distributions with respect to Buyer common stock, in each case without interest thereon, and subject to Section 2.7(g). Any portion of the Exchange Fund remaining unclaimed by holders of Shares as of a date which is immediately prior to such time as such amounts would otherwise escheat to or become property of any Governmental Body, to the extent permitted by applicable Legal Requirements, shall become the property of Buyer free and clear of any claims or interest of any Person previously entitled thereto.

(f) No Liability. Neither Buyer nor NorthStar shall be liable to any former holder of Shares for any such Shares (or dividends or distributions with respect thereto) or cash or other payment delivered to a Governmental Body pursuant to any abandoned property, escheat, or similar Legal Requirements. Buyer and the Exchange Agent shall be entitled to rely upon the stock transfer books of NorthStar to establish the identity of those Persons entitled to receive the Consideration. NorthStar’s stock transfer books shall be conclusive with respect thereto.

(g) Withholding Rights. Each of Buyer and the Exchange Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any former holder of Shares such amounts as it is required to deduct and withhold with respect to the making of such payment under any Legal Requirements relating to Taxes and pay such withholding amount over to the appropriate Governmental Body. To the extent that amounts are so withheld by Buyer or the Exchange Agent, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the former holder of the Shares in respect of which such deduction and withholding was made by Buyer or the Exchange Agent, as the case may be.

2.8 STOCK TRANSFER BOOKS

At the Effective Time, the stock transfer books of NorthStar shall be closed and there shall be no further registration of transfers of Shares thereafter on the records of NorthStar. From and after the Effective Time, the holders of Certificates outstanding immediately prior to the Effective Time shall cease to have any rights with respect to such Shares except as otherwise provided herein or by Legal Requirements. On or after the Effective Time, any Certificates presented to the Exchange Agent or Buyer for any reason shall be converted into the Consideration in accordance with Section 2.5, subject to applicable Legal Requirements in the case of Dissenting Shares.

2.9 BUYER COMMON STOCK

The shares of Buyer common stock issued and outstanding immediately prior to the Effective Time shall be unaffected by the NorthStar Merger, and at the Effective Time, such shares shall remain issued and outstanding.

2.10 ADJUSTMENTS FOR DILUTION AND OTHER MATTERS

Prior to the Effective Time, if Buyer or NorthStar changes (or establishes a record date for changing) the number of shares of Buyer common stock or the number of Shares issued and outstanding as of March 22, 2006, as a result of a stock dividend, stock split, recapitalization, reclassification, combination, or similar transaction with respect to such shares or Shares, and the record date for such transaction is after March 22, 2006, and prior to the Effective Time, then the Consideration shall be appropriately and proportionately adjusted such that the aggregate consideration to be paid by Buyer to holders of Shares pursuant to Section 2.5 would be the same as if the Effective Time had been the close of business on March 22, 2006.

2.11 TREATMENT OF STOCK OPTIONS

The name of each holder of an option to purchase shares of NorthStar common stock (“NorthStar Options”) and the number of NorthStar Options by such option holder are listed on Part 3.3 of the Disclosure Letter, identifying such NorthStar Options as NorthStar Eligible Options, if applicable. NorthStar has delivered in substantially the form attached as Exhibit 2.11 (the “Option Notice”) to be delivered to each holder of a NorthStar Option on or before March 27, 2006. Each NorthStar Eligible Option as to which the holder agrees to take cash in lieu of exercising such NorthStar Eligible Option shall be automatically cancelled at Closing and all rights in respect thereof will cease to exist except the right to receive from NorthStar at Closing the Option Consideration. The Option Notice shall provide that any holder of a NorthStar Eligible Option, whether or not having made the election to receive the Option Consideration, shall not be entitled to receive any portion of such Option Consideration if such holder is not employed by an Acquired Company on the date three (3) days before the receipt by Buyer of all Consents of Governmental Bodies required for the consummation of the Contemplated Transactions. At the time of termination of any NorthStar Option holder’s employment before such date, (a) the applicable Acquired Company shall inform such holder that he or she will not be entitled to share in the Option Consideration and will only have the right to exercise NorthStar Options on or before three (3) days after he or she receives written notice from NorthStar that all Consents of Governmental Bodies required for the consummation of the Contemplated Transactions have been received, subject to NorthStar’s right to require re-sale of the Shares so acquired to NorthStar pursuant to the terms and provisions of the Stockholders Agreement, as amended, or the Restated Stockholders Agreement and (b) the Acquired Companies shall promptly notify Buyer of the termination of such NorthStar Option holder’s employment and update Part 3.3 of the Disclosure Letter to reflect that such holder does not hold NorthStar Eligible Options.

The Acquired Companies have not subleased any real property. NorthStar has delivered or made available to Buyer copies of any instruments (as recorded, if applicable) by which the Acquired Companies acquired such leaseholds and interests and copies of all title insurance policies, opinions, abstracts, and surveys in the possession of the Acquired Companies and relating to such leaseholds or interests.

All material assets reflected in the Balance Sheet and the Interim Balance Sheet are free and clear of all Encumbrances except (a) security interests shown on the Balance Sheet or the Interim Balance Sheet as securing specified liabilities or obligations, with respect to which no default (or event that, with notice or lapse of time or both, would constitute a default) exists, (b) security interests incurred in connection with the purchase of assets after the date of the Interim Balance Sheet (such security interests being limited to the assets so acquired), with respect to which no default (or event that, with notice or lapse of time or both, would constitute a default) exists, and (c) liens for current taxes not yet due.

3.9 ALLOWANCE FOR LOAN LOSSES; LOAN GUARANTEES

The allowances for loan losses reflected on the Acquired Companies’ financial statements have been calculated, in all material respects, as of their respective dates, in a manner consistent with the requirements of GAAP to provide for reasonably anticipated losses on outstanding loans, net of recoveries.

3.10 NO UNDISCLOSED LIABILITIES

Except as set forth in Part 3.10 of the Disclosure Letter, the Acquired Companies have no liabilities or obligations of any nature (whether known or unknown and whether absolute, accrued, contingent, or otherwise) except for liabilities or obligations reflected or reserved against in the Balance Sheet or the Interim Balance Sheet and current liabilities incurred in the Ordinary Course of Business since the respective dates thereof.

3.11 TAXES

(a) The Acquired Companies have filed or caused to be filed all Tax Returns that are or were required to be filed by or with respect to any of them, either separately or as a member of a group of corporations, pursuant to applicable Legal Requirements, and all such federal and state income Tax Returns have been timely filed. NorthStar has made available to Buyer copies of each such Tax Return, and Part 3.11 of the Disclosure Letter contains a complete and accurate list of each type of Tax Return filed since its inception. The Acquired Companies have paid, or made provision for the payment of, all Taxes that have or may have become due pursuant to those Tax Returns or otherwise, or pursuant to any assessment received by any Acquired Company, except such Taxes, if any, as are listed in Part 3.11 of the Disclosure Letter and are being contested in good faith and as to which adequate reserves (determined in accordance with GAAP) have been provided in the Balance Sheet and the Interim Balance Sheet.

(b) The United States federal and state income Tax Returns of each Acquired Company subject to such Taxes are closed by the applicable statute of limitations for all taxable years through 2001. Such Tax Returns have not been audited by the IRS or relevant state tax authorities. Part 3.11 of the Disclosure Letter describes all adjustments to the United States federal income Tax Returns filed by any Acquired Company or any group of corporations including any Acquired Company for all taxable years, and the resulting deficiencies proposed by the IRS. Except as described in Part 3.11 of the Disclosure Letter, no Acquired Company has given or been requested to give waivers or extensions (or is or would be subject to a waiver or extension given by any other Person) of any statute of limitations relating to the payment of Taxes of any Acquired Company or for which any Acquired Company may be liable.

(c) The charges, accruals, and reserves with respect to Taxes on the respective books of each Acquired Company are adequate (determined in accordance with GAAP) and are at least equal to that Acquired Company’s liability for Taxes. There exists no proposed tax assessment against any Acquired Company except as disclosed in the Balance Sheet or in Part 3.11 of the Disclosure Letter. No consent to the application of Section 341(f)(2) of the IRC has been filed with respect to any property or assets held, acquired, or to be acquired by any Acquired Company. All Taxes that any Acquired Company is or was required by Legal Requirements to withhold or collect have been duly withheld or collected and, to the extent required, have been paid to the proper Governmental Body or other Person.

During the consistency period (as defined in Section 338(h)(4) of the IRC with respect to conversion of the Shares), no Acquired Company or target affiliate (as defined in Section 338(h)(6) of the IRC with respect to the conversion of the Shares) has sold or will sell any property or assets to Buyer or to any member of the affiliated group (as defined in Section 338(h)(5) of the IRC) that includes Buyer. Part 3.11 of the Disclosure Letter lists all such target affiliates.

9.	INDEMNIFICATION; REMEDIES

9.1

SURVIVAL; RIGHT TO INDEMNIFICATION NOT AFFECTED BY KNOWLEDGE

All representations, warranties, covenants, and obligations in this Agreement, the Disclosure Letter, the supplements to the Disclosure Letter, the certificate delivered pursuant to Section 7.2(d)(vi), and any other certificate or document delivered pursuant to this Agreement will survive the Closing. The right to indemnification, payment of Damages, or other remedy based on such representations, warranties, covenants, and obligations will not be affected by any investigation conducted by, or any Knowledge capable of being acquired by, Buyer, or its affiliates or representatives at any time, whether before or after the execution and delivery of this Agreement or the Closing Date, with respect to the accuracy or inaccuracy of or compliance with, any such representation, warranty, covenant, or obligation. The waiver of any condition based on the accuracy of any representation or warranty, or on the performance of or compliance with any covenant or obligation, will not affect the right to indemnification, payment of Damages, or other remedy based on such representations, warranties, covenants, and obligations.

9.2 INDEMNIFICATION AND PAYMENT OF DAMAGES

Upon the effectiveness of the NorthStar Merger, the NorthStar stockholders, jointly and severally, shall be deemed to indemnify and hold harmless Buyer, the Acquired Companies, and their respective Representatives, stockholders, controlling persons, and affiliates (collectively, the “Indemnified Persons”) for, and will pay to the Indemnified Persons the amount of, any loss, liability, claim, damage (including incidental and consequential damages), expense (including costs of investigation and defense and reasonable attorneys’ fees) or diminution of value, whether or not involving a third-party claim (collectively, “Damages”), arising, directly or indirectly, from or in connection with:

(a) any Breach of any representation or warranty made by the Acquired Companies in this Agreement (without giving effect to any supplement to the Disclosure Letter), the Disclosure Letter, the supplements to the Disclosure Letter, or any other certificate or document delivered by the Acquired Companies pursuant to this Agreement;

(b) any Breach of any representation or warranty made by the Acquired Companies in this Agreement as if such representation or warranty were made on and as of the

Closing Date without giving effect to any supplement to the Disclosure Letter, other than any such Breach that is disclosed in a supplement to the Disclosure Letter and is expressly identified in the certificate delivered pursuant to Section 7.2(d)(vi) as having caused the condition specified in Section 7.2 not to be satisfied;

(d) any Breach by Seller Representative of any covenant or obligation of Seller Representative in this Agreement or any NorthStar Closing Document;

(e) any services provided by any Acquired Company prior to the Closing Date;

(f) any matter disclosed in Part 3.6 (NorthStar Loans USA) of the Disclosure Letter;

(g) any claim by a holder of a NorthStar Option with respect to treatment of such Option or the Option Notice or Option Consideration; or

(h) any claim by any Person for brokerage or finder’s fees or commissions or similar payments based upon any agreement or understanding alleged to have been made by any such Person with any Acquired Company (or any Person acting on their behalf) in connection with any of the Contemplated Transactions.

To the extent of cash and stock available in the Escrow, all payment of Damages to Buyer shall be made from the Escrow Fund, pro-rata based on the interests of all NorthStar stockholders therein, and there shall be no distinction between the portion of the Escrow Fund represented by cash and the portion represented by the Buyer’s common stock. Damages related to a breach of warranty of Section 3.3 regarding ownership of Shares and the absence of Encumbrances thereon shall be paid first from the portion of the Escrow Fund attributable to the individual NorthStar stockholder to whom the breach of Section 3.3 relates, and only thereafter from the Escrow Fund for the accounts of the other NorthStar stockholders. Nothing in this Agreement shall bar or adversely affect the rights of such other NorthStar stockholders to claim indemnity or subrogation rights against any NorthStar stockholder to whom the breach of Section 3.3 relates.

For purposes of this Section 9, in determining the amount of any Damages, any qualifications or limitations as to materiality (whether by reference to a material adverse change or otherwise) contained in any representation, warranty, covenant, or obligation shall be disregarded, as it is the parties’ intention that the $180,000 threshold amount for indemnification set forth in Section 9.5 be the sole measure of materiality for all representations, warranties, covenants, and obligations in the aggregate. The remedies provided in this Section 9.2 will not be exclusive of or limit any other remedies that may be available to Buyer or the other Indemnified Persons.

9.3

INDEMNIFICATION AND PAYMENT OF DAMAGES — ENVIRONMENTAL MATTERS

In addition to the provisions of Section 9.2, the NorthStar stockholders, jointly and severally, will indemnify and hold harmless Buyer, the Acquired Companies, and the other Indemnified Persons for, and will pay to Buyer, the Acquired Companies, and the other Indemnified Persons the amount of, any Damages (including costs of cleanup, containment, or other remediation) arising, directly or indirectly, from or in connection with:

(a) any Environmental, Health, and Safety Liabilities arising out of or relating to: (i) (A) the ownership, operation, or condition at any time on or prior to the Closing Date of the Facilities or any other properties and assets (whether real, personal, or mixed and whether tangible or intangible) in which any Acquired Company has or had an interest, or (B) any Hazardous Materials or other contaminants that were present on the Facilities or such other properties and assets at any time on or prior to the Closing Date; or (ii) (A) any Hazardous Materials or other contaminants, wherever located, that were, or were allegedly, generated, transported, stored, treated, Released, or otherwise handled by any Acquired Company or by any other Person for whose conduct they are or may be held responsible at any time on or prior to the Closing Date, or (B) any Hazardous Activities that were, or were allegedly, conducted by any Acquired Company or by any other Person for whose conduct they are or may be held responsible; or

(b) any bodily injury (including illness, disability, and death, and regardless of when any such bodily injury occurred, was incurred, or manifested itself), personal injury, property damage (including trespass, nuisance, wrongful eviction, and deprivation of the use of real property), or other damage of or to any Person, including any employee or former employee of any Acquired Company or any other Person for whose conduct they are or may be held responsible, in any way arising from or allegedly arising from any Hazardous Activity conducted or allegedly conducted with respect to the Facilities or the operation of the Acquired Companies prior to the Closing Date, or from Hazardous Material that was (i) present or suspected to be present on or before the Closing Date on or at the Facilities (or present or suspected to be present on any other property, if such Hazardous Material emanated or allegedly emanated from any of the Facilities and was present or suspected to be present on any of the Facilities on or prior to the Closing Date) or (ii) Released or allegedly Released by any Acquired Company or any other Person for whose conduct they are or may be held responsible, at any time on or prior to the Closing Date.

Buyer will be entitled to control any Cleanup, any related Proceeding, and any other Proceeding with respect to which indemnity may be sought under this Section 9.3.

9.4 TIME LIMITATIONS

If the Closing occurs, the NorthStar stockholders will have no liability (for indemnification or otherwise) with respect to any representation or warranty, or covenant or obligation to be performed and complied with prior to the Closing Date, unless on or before the date that is fifteen (15) months after the Closing Date, Buyer notifies the Escrow Agent and Seller Representative of a claim specifying the factual basis of that claim in reasonable detail to the extent then known by Buyer, except that each NorthStar stockholder will have continuing liability with respect to fraud or intentional misrepresentation by such stockholder.

9.5 LIMITATIONS ON AMOUNT

The NorthStar stockholders will have no liability (for indemnification or otherwise) with respect to the matters described in Sections 9.2 (other than subsection 9.2(g)) and 9.3 (a) until the total of all Damages with respect to such matters exceeds $180,000, and then only for the amount by which such Damages exceed $180,000 and (b) to the extent such Damages exceed the Escrow (including any interest, dividends, and distributions thereon), unless such Damages arise from or in connection with fraud or intentional misrepresentation by such stockholder.

9.6 PROCEDURE FOR INDEMNIFICATION

Promptly after receipt by an Indemnified Person of the commencement of any Proceeding against it or the discovery by an Indemnified Person of a claim for Damages, such Indemnified Person will give notice to the Escrow Agent and Seller Representative of such claim, but the failure to notify the Escrow Agent and Seller Representative promptly will not relieve the NorthStar stockholders of any liability that they may have to any Indemnified Person (subject to the provisions of Section 9.4). Buyer shall have the exclusive right to defend, compromise, or settle such Proceeding or claim. The Escrow Agent shall promptly reimburse an Indemnified Person after receipt of notice from the Escrow and pursuant to the Escrow Agreement.

10.

The rights and remedies of the parties to this Agreement are cumulative and not alternative. Neither the failure nor any delay by any party in exercising any right, power, or privilege under this Agreement or the documents referred to in this Agreement will operate as a waiver of such right, power, or privilege, and no single or partial exercise of any such right, power, or privilege will preclude any other or further exercise of such right, power, or privilege or the exercise of any other right, power, or privilege.

10.8 ENTIRE AGREEMENT AND MODIFICATION

This Agreement supersedes all prior agreements between the parties with respect to its subject matter (including the Letter from Buyer to NorthStar dated December 14, 2005) and constitutes (along with the documents referred to in this Agreement) a complete and exclusive statement of the terms of the agreement between the parties with respect to its subject matter.

10.9 DISCLOSURE LETTER

The disclosures in the Disclosure Letter, and those in any supplement thereto, must relate only to the representations and warranties in the Section of this Agreement to which they expressly relate and not to any other representation or warranty in this Agreement.

10.16 SELLER REPRESENTATIVE

Concurrently with the Effective Time, each NorthStar stockholder shall, as a condition to his/her participation in the NorthStar Merger and receipt of the Consideration after the Closing, be deemed to appoint ▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇ to act as a representative for such NorthStar stockholder (“Seller Representative”), and ▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇ hereby accepts such appointment. Seller Representative shall have the authority to execute any and all instruments and other documents concerning the Contemplated Transactions on behalf of the NorthStar stockholders and to do any and all other acts or things on behalf of the NorthStar stockholders, which Seller Representative may deem necessary or advisable on behalf of the NorthStar stockholders or which may be required by this Agreement or the NorthStar Closing Documents in connection with the consummation of the Contemplated Transactions. Without limiting the generality of the foregoing, Seller Representative shall have full and exclusive authority to:

(a) agree with Buyer with respect to any matter or thing required by or deemed necessary by Seller Representative in connection with this Agreement or the NorthStar Closing Documents, including without limitation any amendments thereto;

(b) give and receive notices on behalf of the NorthStar stockholders, except as to the notices referenced in Sections 2.5(e), 2.6 and 2.7 of this Agreement;

(c) generally do all things and perform all acts, including without limitation executing and delivering all agreements, certificates, receipts, consents, elections, instructions, and other instruments or documents contemplated by or deemed necessary or advisable by Seller Representative in connection with this Agreement or the NorthStar Closing Documents;

(d) take all actions necessary or desirable in connection with the operation of this Agreement or the Escrow Agreement, including enforcement of amounts due NorthStar stockholders under the Escrow Agreement and defense and/or settlement of any indemnification or other claims made by Indemnified Persons pursuant to Section 9 of this Agreement or the Escrow Agreement; and

All decisions by Seller Representative shall be binding upon each NorthStar stockholder. The NorthStar stockholders shall not have any right to object, dissent, protest, or otherwise contest Seller Representative’s decisions. Buyer shall be entitled to rely upon, and shall be fully protected in relying upon, any notice or document received by or from Seller Representative and any action taken or decision made by Seller Representative on behalf of any NorthStar stockholder. If ▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇ resigns or becomes unable to perform his duties under this Section 10.16, NorthStar shall promptly select a new Seller Representative and such new Seller Representative shall promptly execute and deliver to Buyer a supplement to this Agreement agreeing to the terms of this Section 10.16.

No compensation shall be paid to the Seller Representative for serving in this capacity; provided, however, that if the Seller Representative incurs out-of-pocket expenses in connection herewith, the Seller Representative shall be entitled to reimbursement of all such expenses. The Seller Representative shall maintain (at the offices of NorthStar) invoices and other evidences of the expenses reimbursed. Any payments due to NorthStar stockholders under the Escrow Agreement shall first be applied to reimburse the Seller Representative for his out-of-pocket expenses, upon notice delivered to Escrow Agent of the amount to be reimbursed.

Except as to the obligations specifically required of the Seller Representative under this Agreement and the Escrow Agreement, the Seller Representative shall not be responsible for the obligations of the Acquired Companies or be obligated to the Buyer for Damages, except to the extent the Seller Representative is also a stockholder of NorthStar and except for his bad faith, gross negligence or willful conduct.

Seller Representative shall not be liable to the NorthStar stockholders with respect to any action taken or suffered by him in reliance upon any notice, direction, instruction, consent or statement or other paper or document believed by him to be genuine and duly authorized, nor for anything except his own willful conduct, bad faith or gross negligence. All conduct of the Seller Representative shall be undertaken in good faith and he shall not, as the result of his acting as Seller Representative, be responsible for the validity, enforceability or collectibility of any of the obligations of any of the other parties to the Merger Agreement.

Seller Representative shall be entitled to indemnification from and be held harmless by the NorthStar stockholders against any loss, expense (including reasonable attorneys’ fees) or other liability arising out of his service as Seller Representative under this Agreement, other than for harm directly caused by his willful misconduct, bad faith or gross negligence, and in such event he shall be entitled to payment thereof from the Escrow Fund out of amounts otherwise payable to the NorthStar stockholders.
