(c) The term “Capital Expenditure Shortfall” means the amount by which (x) the aggregate amount of capital expenditures made by the Sellers and the Acquired Companies in respect of the Acquired Business prior to the Closing Date is less than (y) the product of (A) $9 million multiplied by (B) the quotient of the number of days elapsed in 2007 prior to the Closing Date divided by 365.

(d) The term “Net Payment Amount” means a working capital assets and pro ration net payment amount corresponding to the “Net Payment Amount” set forth on Annex A, with such amount to be computed as of the close of business on the Business Day immediately prior to the Closing Date, in a manner consistent as to line items, accounting principles, methods of allocation and pro ration, and in all other significant respects, with the computation of Net Payment Amount set forth in Annex A. Such amount shall be expressed as a negative number if in favor of the Buyer or as a positive number if in favor of the Sellers.

1.9 Purchase Price Adjustment.

(a) The Sellers shall, no later than 20 Business Days prior to the expected Closing Date begin preparing, and shall deliver to the Buyer no later than ten Business Days prior to the expected Closing Date, a statement (the “Estimated Closing Statement”) setting forth ARC’s good faith estimate of the Adjustment Amount (the “Estimated Adjustment Amount”) and each of the components thereof. The Estimated Closing Statement shall be prepared in consultation with the Buyer and shall be reasonably acceptable to the Buyer. Promptly upon the Buyer’s request, ARC shall make available to the Buyer and its Representatives copies of any back-up materials used by ARC in preparing the Estimated Closing Statement and such other materials as the Buyer may reasonably request in connection with its review of the Estimated Closing Statement.

(b) Within 90 days after the Closing Date, the Buyer shall cause to be prepared and delivered to ARC a statement (the “Closing Statement”) setting forth the Buyer’s good faith determination the Adjustment Amount and each of the components thereof. Promptly upon ARC’s request, the Buyer shall make available to ARC and its Representatives copies of any back-up materials used by the Buyer in preparing the Closing Statement and such other materials as ARC may reasonably request in connection with their review of the Closing Statement.

(c) Within 30 days after ARC’s receipt of the Closing Statement, ARC shall deliver to the Buyer a written statement either accepting the Closing Statement or specifying any objections thereto. If ARC does not deliver any such objections within such 30 day period, the Closing Statement shall become final and binding upon all parties. If ARC does deliver such objections within such period, then the parties shall negotiate in good faith for a period of 15 days following the Buyer’s receipt of such objections to resolve any such objections. If the parties are able to resolve ARC’s objections during such 15 day period, then the Closing Statement, as revised in accordance with such resolution, shall become final and binding upon all parties. If the parties are not able to resolve such objections during such period, then any remaining disputes shall be resolved by a nationally recognized accounting firm upon which ARC and the Buyer shall reasonably agree (the “Accounting Firm”). The Accounting Firm shall be instructed to resolve any such disputes within 30 days after its appointment. The resolution of such disputes by the Accounting Firm shall be set forth in writing and binding, shall be within the range of dispute between the Buyer and ARC and shall be conclusive upon all parties. Upon delivery of such resolution, the Closing Statement, as modified in accordance with such resolution, and the Adjustment Amount as modified in accordance with such resolution and set forth therein (the “Final Adjustment Amount”), shall become final and binding upon all Parties. The fees and expenses of the Accounting Firm shall be shared equally by the Buyer and the Sellers.

(d) Within three Business Days after the date on which the Closing Statement becomes final and binding in accordance with Section 1.9(b), (i) if the Final Adjustment Amount is less than the Estimated Adjustment Amount, ARC shall pay cash in the amount of such shortfall to the Buyer by wire transfer of immediately available funds to an account designated by the Buyer at least two Business Days prior to such payment; and (ii) if the Final Adjustment Amount is greater than the Estimated Adjustment Amount, the Buyer shall pay cash in the amount of such shortfall to ARC by wire transfer of immediately available funds to an account designated by the ARC at least two Business Days prior to such payment. Any such payment shall be made with interest at the Prime Rate from the Closing Date to the date of payment.

1.10 Calculation of Final Purchase Price. The “Final Purchase Price” shall be the amount equal to the Initial Purchase Price reduced by the Expense Payments Amount, if any, and reduced by the absolute value of the Adjustment Amount, if the Adjustment Amount is a negative number.

1.11 Closing. The parties agree that the closing of the Transaction (the “Closing”) shall take place at 10:00 a.m. local time, at the offices of Paul, Weiss, Rifkind, Wharton & Garrison LLP, 1285 Avenue of the Americas, New York, New York 10019-6064, as soon as practicable, but in any event not later than the fourth Business Day immediately following the date on which the last of the conditions set forth in Article VII (other than those conditions that by their nature have to be satisfied at the Closing, but subject to the satisfaction or waiver of those conditions) are satisfied or waived, or at such other date, time and place as the Parties may agree. The date on which the Closing will occur is referred to herein as the “Closing Date,” and the time at which the Closing occurs is referred to herein as the “Effective Time.” If the Sellers determine that such delay is necessary to satisfy the conditions to closing set forth in either Section 7.1(e) or 7.1(f), the Sellers shall have a one time option, by delivering written notice to Buyer no later than ten (10) days prior to the Closing Date, to delay the Closing Date to a date designated in such notice that is no more than 45 days following the date on which the Sellers would otherwise have been required to effect the Closing (but in no event later than the End Date).

1.12 Closing Deliveries. At the Closing:

(a) The Buyer shall deliver to the Sellers the amount in cash equal to the Closing Payment by wire transfer of immediately available funds to the bank account or accounts designated by the Sellers prior at least one Business Day to the Closing;

(b) Each Seller shall deliver an Assignment Agreement to the Buyer transferring all Acquired Company Interests held by such Seller to the Buyer, in form and substance attached hereto as Exhibit A (each, an “Interest Assignment Agreement”), and duly executed by such Seller;

(c) Each Seller shall deliver an Assignment Agreement to the Buyer transferring all of such party’s Acquired Assets to the Buyer, in form and substance attached hereto as Exhibit B (each, an “Asset Assignment Agreement”), and duly executed by such Party;

(d) Each Seller, and the Buyer shall deliver a Trademark Assignment Agreement transferring all of such Seller’s Trademarks and related Assets to the Buyer, in form and substance attached hereto as Exhibit C (each, a “Trademark Assignment Agreement”), and duly executed by such Parties;

(e) ARC and the Buyer shall deliver a Transition Services Agreement, the purpose of which is to, among other things, designate the services, support and facilities use relating to the operation of the Retained Business that the Buyer will provide to ARC and its Affiliates after the Closing Date, in form and substance attached hereto as Exhibit D (the “Transition Services Agreement”), and duly executed by such Parties; and

(f) Each Party shall deliver the other documents required to be delivered by it pursuant to Article VII hereof and such other documents or instruments as may reasonably be required by the other Parties to effect the transactions contemplated hereby.

1.13 Change in Transaction Structure. If and to the extent that Buyer determines, not less than 10 days prior to the Closing, that it would be beneficial to transfer one or more of the Acquired Properties from its current owner at the Closing to an entity designated by the Buyer, then Sellers shall reasonably cooperate with Buyer in effecting such transfer; provided, however, that no such transfer shall (i) have the effect of increasing the obligations or reducing the rights of the Sellers hereunder in any respect greater than de minimis or increasing the costs or expenses of the Sellers hereunder, including increasing the amount of any Taxes due by the Sellers (unless Buyer pays such increased cost or expense including attorney’s fees, title fees and transfer taxes associated with such transfers), (ii) reasonably be expected to impede or delay the consummation of the transactions contemplated hereby on the terms contemplated herein or (iii) constitute a waiver of any condition to the transactions provided herein.

1.14 Delayed Acquisition Assets.

(a) Subject to Section 7.2(g), if and to the extent that the transfer or assignment from any Seller to Buyer of any Acquired Asset or any Acquired Company Interest would be a violation of applicable Law with respect to such Acquired Asset or Acquired Company Interest or otherwise adversely affect the rights of the transferee thereunder as a result of the failure to obtain or make any consent, approval, waiver, authorization, notice or filing required to be made in connection with the transactions contemplated by this Agreement, other than any consent, approval, waiver, authorization, notice or filing in respect of Assumed Indebtedness (to which this Section 1.14 shall not

apply), then the transfer or assignment to Buyer of such Acquired Asset or Acquired Company Interest (each, a “Delayed Acquired Asset”) shall be automatically deemed deferred and any such purported transfer or assignment shall be null and void until such time as all legal impediments are removed and/or any required authorizations have been made or obtained, but the Closing shall otherwise take place in all respects as provided for in this Agreement and the Initial Purchase Price shall not be reduced.

(b) If the transfer or assignment of any Acquired Asset or Acquired Company Interest intended to be transferred or assigned hereunder is not consummated at the Closing as a result of such Acquired Asset or Acquired Company Interest being a Delayed Acquired Asset, then the applicable Seller shall thereafter, directly or indirectly, hold such Delayed Acquired Asset for the use and benefit of Buyer (at the expense of Buyer), insofar as reasonably possible. In addition, to the extent not prohibited by Law, such Seller shall take or cause to be taken such other actions as may be reasonably requested by Buyer in order to place Buyer, insofar as reasonably possible, in the same position as if such Delayed Acquired Asset had been transferred as contemplated hereby and so that all the benefits and burdens relating to such Delayed Acquired Asset, including possession, use, risk of loss, potential for gain, and dominion, control and command over such Delayed Acquired Asset, are to inure from and after the Closing to Buyer. To the extent permitted by Law and to the extent otherwise permissible in light of any required consent or authorization, Buyer shall be entitled to, and shall be responsible for, the management of any Delayed Acquired Assets not yet transferred to it as a result of this Section 1.14 and the parties hereto agree to use commercially reasonable efforts to cooperate and coordinate with respect thereto.

(c) If and when the consent or authorization, the absence of which caused the deferral of transfer of any Acquired Asset or Acquired Company Interest pursuant to this Section 1.14 is obtained, the transfer of the applicable Acquired Asset or Acquired Company Interest to Buyer shall automatically and without further action be effected in accordance with the terms of this Agreement and the applicable Transaction Documents.

(d) Prior to the Closing Date, the Sellers shall deliver to Buyer a list identifying, in reasonable detail, to the Knowledge of the Sellers, the Delayed Acquired Assets and the authorizations required therefore (provided that this provision shall be disregarded for purposes of Section 7.2(a) and Article IX).

(e) The parties hereto further agree that, assuming as set forth in Section 1.14(b) that all or substantially all of the benefits and burdens relating to the Acquired Assets inure to Buyer, (i) any Delayed Acquired Assets referred to in this Section 1.14(e) shall be treated for all income Tax purposes as Assets of Buyer and (ii) neither Buyer nor Seller shall take, and each of Buyer and Seller shall prevent any of their respective Affiliates from taking, any position inconsistent with such treatment for any income Tax purposes (unless required by a change in applicable income Tax Law or a good faith resolution of a contest).

5.3 Commercially Reasonable Efforts. Subject to the terms and conditions of this Agreement, each Buyer and each Seller shall, and the Sellers shall (prior to the Closing) cause the Acquired Companies to, use their respective commercially reasonably efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable under applicable Law to consummate the transactions contemplated by this Agreement, including preparing and filing as promptly as practicable all documentation to effect all necessary filings, notices, petitions, statements, registrations, submissions of information, applications and other documents, and to obtain all consents and authorizations, necessary to consummate the transactions contemplated by this Agreement. The Sellers and the Acquired Companies shall use commercially reasonable efforts to obtain the Company Required Consents and the Seller Required Consents. The Buyer shall use commercially reasonable efforts to obtain the Buyer Required Consents. The Parties shall cooperate with each other in connection with the foregoing. From the date hereof until the receipt of the ARC Stockholder Approval, ARC shall not issue Equity Securities of any class in an amount equal to or more than five percent (5%) of the number of outstanding Equity Securities of such class to any Person or to any group (as defined in Rule 13d-5 under the Exchange Act) unless such Person or group concurrently therewith executes an agreement in favor of the Buyer that is substantially identical to the Support Agreement.

5.4 Access.

(a) From the date hereof until the Closing Date, upon reasonable notice, the Sellers shall afford the Buyer and its Representatives reasonable access to each Acquired Companies’ (and Sellers’ in respect of the Acquired Business) properties, offices, plants and other facilities, books and records, and shall furnish the Buyer with such financial, operating and other data and information as the Buyer may reasonably request; provided, however, that any such access or furnishing of information shall be conducted, during normal business hours, under the supervision of such Acquired Companies’ or Sellers’ personnel, in such a manner as not unreasonably to interfere with the normal operations of such Acquired Company or the Seller and the Buyer shall reimburse the Sellers for reasonable out-of-pocket expenses incurred by the Sellers in providing such information. In furtherance of the foregoing, to the fullest extent permitted under applicable Law, not later than five (5) Business Days from the date hereof, ARC shall appoint four (4) individuals with knowledge of, and experience in, the operations and affairs of the Acquired Business and the Buyer shall appoint three (3) employees with responsibility for overseeing the operational integration of the Acquired Business with the Buyer’s business, to comprise a transition team that shall meet on a regular basis to discuss and implement reasonable steps necessary to achieve an orderly integration of the Acquired Business with the Buyer as of the Closing. Notwithstanding anything to the contrary in this Agreement, no Seller shall be required to disclose any information to the Buyer or its Representatives if such disclosure would, in such Seller’s good faith determination, reasonably be expected to, (1) waive any attorney-client or other legal privilege or (2) contravene any applicable Laws, fiduciary duty or binding agreement entered into prior to the date hereof; provided, that the Sellers shall inform the Buyer when information is withheld pursuant to this sentence and the Parties shall use commercially reasonable efforts to permit such disclosure in a manner consistent with the preservation of any such privilege or in compliance with any such applicable Law, duty or agreement. No investigation or information provided or received by the Buyer or its Representatives pursuant to this Section 5.4 or otherwise will affect any of the representations or warranties of the Sellers contained in this Agreement. Notwithstanding anything else in this agreement, including in this Section 5.4, prior to the Closing the Buyer shall not be permitted to market, hold open for sale or otherwise discuss with any other parties the sale or other disposition of any of the Acquired Properties or the Acquired Assets; provided that, prior to the Closing, the Buyer shall be permitted to market, hold open for sale or otherwise discuss with other parties the sale or other disposition of (i) the properties listed in Section 5.4(a)(i) of the Buyer Disclosure Letter and (ii) with the consent of ARC (such consent not to be unreasonably withheld or delayed), any 20 of the properties listed in Section 5.4(a)(ii) of the Buyer Disclosure Letter.

(b) In order to facilitate the resolution of any claims made against or incurred by the Sellers (as it relates to the Acquired Business), for a period of seven (7) years after the Closing, the Buyer shall (i) retain the books and records relating to the Acquired Business relating to periods prior to the Closing and (ii) afford the Representatives of the Sellers reasonable access (including the right to make, at the Sellers’ expense, photocopies), during normal business hours, to such books and records; provided, however, that the Buyer shall notify the Sellers in writing at least thirty (30) days in advance of destroying any such books and records prior to the seventh (7th) anniversary of the Closing Date in order to provide the Sellers the opportunity to copy (at the Sellers’ expense) such books and records in accordance with this Section 5.4.

(c) In order to facilitate the resolution of any claims made against or incurred by the Buyer, for a period of seven (7) years after the Closing, the Sellers shall (i) retain the books and records relating to the Acquired Business relating to periods prior to the Closing and (ii) afford the Representatives of the Buyer reasonable access (including the right to make, at the Sellers’ expense, photocopies), during normal business hours, to such books and records; provided, however, that the Sellers shall notify the Buyer in writing at least thirty (30) days in advance of destroying any such books and records prior to the seventh (7th) anniversary of the Closing Date in order to provide the Buyer the opportunity to copy (at the Buyer’s expense) such books and records in accordance with this Section 5.4.

5.5 No Solicitation.

(a) Except as otherwise provided in this Section 5.5, ARC agrees that it shall not, and that it shall not permit its Affiliates or its or its Affiliates’ officers, directors, employees, agents or representatives, including any investment banker, attorney or accountant retained by them (“Representatives”), to, directly or indirectly, (i) initiate, solicit, knowingly encourage (including by providing information) or facilitate any inquiries, proposals or offers with respect to, or the making or completion of, an Alternative Proposal, (ii) engage or participate in any negotiations or discussions concerning, or provide or cause to be provided any non-public information or data relating to ARC, the Acquired Companies or the Acquired Business in connection with, or have any discussions with any person relating to, an actual or proposed Alternative Proposal, or otherwise knowingly encourage or facilitate any effort or attempt to make or implement an Alternative Proposal, (iii) approve, endorse or recommend, or propose publicly to approve, endorse or recommend, any Alternative Proposal, (iv) approve, endorse or recommend, or propose to approve, endorse or recommend, or execute or enter into, any letter of intent, agreement in principle, merger agreement, acquisition agreement, option agreement or other similar agreement relating to any Alternative Proposal, (v) amend, terminate, waive or fail to enforce, or grant any consent under, any confidentiality, standstill or similar agreement or (vi) resolve to propose or agree to do any of the foregoing; provided, however, it is understood and agreed that any determination or action by the Board of Directors of ARC permitted under Section 5.5(c) or (d) shall not be deemed to be a breach or violation of this Section 5.5(a). Without limiting the foregoing, it is understood that any violation of the foregoing restrictions by any Subsidiary of ARC or Representatives of ARC or any of its Subsidiaries shall be deemed to be a breach of this Section 5.5 by ARC.

(b) ARC shall, shall cause each of its Subsidiaries to, and shall direct each of its Representatives to, immediately cease any existing solicitations, discussions or negotiations with any Person (other than the Parties hereto) that has made or indicated an intention to make an Alternative Proposal.

(c) Notwithstanding anything to the contrary in Section 5.5(a) or (b), ARC may, at any time prior to obtaining the ARC Stockholder Approval, in response to a bona fide unsolicited, written Alternative Proposal made after the date hereof and which did not result from or arise in connection with a breach of this Section 5.5 and which the Board of Directors

of ARC determines, in good faith, after consultation with its outside counsel and financial advisors, may reasonably be expected to lead to a Superior Proposal, (i) furnish non-public information with respect to ARC and its Subsidiaries to the person making such Alternative Proposal and its Representatives pursuant to a customary confidentiality agreement no less restrictive of the other party than the Confidentiality Agreements and (ii) participate in discussions or negotiations with such person and its Representatives regarding such Alternative Proposal; provided, however, (i) that the Buyer shall be entitled to receive an executed copy of such confidentiality agreement prior to or substantially simultaneously with ARC furnishing information to the person making such Alternative Proposal or its Representatives and (ii) that ARC shall simultaneously provide or make available to the Buyer any non-public information concerning ARC that is provided to the person making such Alternative Proposal or its Representatives which was not previously provided or made available to the Buyer.

(d) Neither the Board of Directors of ARC nor any committee thereof shall (i) withdraw or modify in a manner adverse to the Buyer or publicly propose to withdraw or modify in a manner adverse to the Buyer, the Recommendation, (ii) approve any letter of intent, agreement in principle, acquisition agreement or similar agreement relating to any Alternative Proposal, (iii) approve or recommend, or publicly propose to approve, endorse or recommend, any Alternative Proposal (clause (i) or (iii), a “Change in Recommendation”). Notwithstanding the foregoing, the Board of Directors of ARC may, at any time prior to obtaining the ARC Stockholder Approval, in response to a bona fide, unsolicited, written Alternative Proposal made after the date hereof and which did not result from or arise in connection with a breach of this Section 5.5 and which the Board of Directors of ARC determines, in good faith, after consultation with its outside counsel and financial advisors, constitutes a Superior Proposal, make a Change in Recommendation or terminate this Agreement pursuant to Section 8.1(c)(iii) (and subject to the terms thereof); provided, that the Board of Directors of ARC shall not be entitled to exercise its right to make a Change in Recommendation or terminate this Agreement pursuant to Section 8.1(c)(iii) unless ARC has: (A) complied in all respects with this Section 5.5, (B) provided to the Buyer four Business Days’ prior written notice (such notice, a “Notice of Superior Proposal”) advising the Buyer that the Board of Directors of ARC intends to take such action and specifying the reasons therefor, including the material terms and conditions of any Superior Proposal that is the basis of the proposed action by the Board of Directors (it being understood and agreed that any material amendment to the financial terms or any other material term of any such Superior Proposal shall require a new Notice of Superior Proposal and an additional three Business Day period), (C) provided to the Buyer all materials and information delivered or made available to the Person or group of Persons making any Superior Proposal in connection with such Superior Proposal, (D) during such four Business Day period (or three Business Day period in the case of an amendment), if requested by the Buyer, engaged in good faith negotiations with the Buyer to propose amendments to this Agreement such that any Alternative Proposal which was determined to constitute a Superior Proposal no longer is a Superior Proposal, and (E) at the end of such four Business Day period (or three Business Day period in the case of an amendment), such Alternative Proposal has not been withdrawn and continues to constitute a Superior Proposal (after giving effect to any amendments to this Agreement that may be

proposed by the Buyer following a Notice of Superior Proposal, as a result of the negotiations required by clause (D) or otherwise).

(e) ARC promptly (and in any event within 24 hours) shall advise the Buyer orally and in writing of (i) any Alternative Proposal or indication or inquiry with respect to or that would reasonably be expected to lead to any Alternative Proposal, (ii) any request for non-public information relating to ARC or its Subsidiaries that is reasonably expected to be related to an Alternative Proposal, and (iii) any inquiry or request for discussion or negotiation regarding an Alternative Proposal, including, in each case, the identity of the person making any such Alternative Proposal or indication or inquiry and the material terms of any such Alternative Proposal or indication or inquiry (including copies of any document or correspondence evidencing such Alternative Proposal or inquiry). ARC shall keep the Buyer reasonably informed on a reasonably current basis of the status (including any material change to the terms thereof) of any such Alternative Proposal or indication or inquiry.

(f) Nothing contained in this Agreement shall prohibit ARC or its Board of Directors from disclosing to its stockholders a position contemplated by Rules 14d-9 and 14e-2(a) promulgated under the Exchange Act; provided, however, that (i) compliance with such rules shall in no way limit or modify the effect that any such action pursuant to such rules has under this Agreement and (ii) in no event shall ARC or its Board of Directors take, or agree or resolve to take, any action that would constitute a Change in Recommendation other than in compliance with this Section 5.5.

(g) As used in this Agreement, “Alternative Proposal” shall mean any inquiry, proposal or offer from any Person or group of Persons other than the Buyer or one of its Affiliates for (i) a merger, reorganization, consolidation, share exchange, business combination, recapitalization, liquidation, asset sale or purchase, dissolution or similar transaction involving ARC (or any Subsidiary or Subsidiaries of ARC whose businesses or assets account for 20% or more of the net revenues, net income or assets of ARC and its Subsidiaries, taken as a whole), (iii) any proposal for the issuance by ARC of 20% or more of any class of its Equity Interests or (iv) any proposal or offer to acquire in any manner, directly or indirectly, 20% or more of any class of Equity Interests of ARC or of the consolidated total assets of ARC and its Subsidiaries, in each case other than the transactions contemplated by this Agreement.

(h) As used in this Agreement, “Superior Proposal” shall mean any bona fide offer made by a third party that if consummated would result in such person (or its stockholders) owning, directly or indirectly, more than 50% of the common stock of ARC then outstanding (or of the Equity Interests of the surviving entity in a merger or the ultimate parent of the surviving entity in a merger), or all or substantially all of the Acquired Assets, which the Board of Directors of ARC reasonably determines (after consultation with its legal advisors and its financial advisors), taking into account all financial, legal, regulatory and

other aspects of such proposal and the Person making the proposal, (i) to be (A) more favorable to the stockholders of ARC than the transactions contemplated by this Agreement after taking into account the then outstanding proposal of the Buyer (including any amendments to this Agreement proposed by the Buyer pursuant to Section 5.5(d) or otherwise) and (B) reasonably capable of being completed on the terms set forth in the proposal and (ii) for which financing, to the extent required, is then committed or reasonably likely to be obtained.

5.6 Filings; Other Actions.

(a) As promptly as reasonably practicable following the date hereto, ARC shall prepare and file with the SEC the Proxy Statement. ARC and the Buyer shall cooperate with each other in connection with the preparation of the Proxy Statement. ARC will use its reasonable best efforts to have the Proxy Statement cleared by the SEC as promptly as practicable after such filing. ARC will use its reasonable best efforts to cause the Proxy Statement to be mailed to ARC’s stockholders as promptly as practicable after the Proxy Statement is cleared by the SEC. ARC shall as promptly as practicable notify the Buyer of the receipt of any oral or written comments from the SEC relating to the Proxy Statement. If at any time prior to the Effective Time, any information should be discovered by any Party hereto which should be set forth in an amendment or supplement to the Proxy Statement so that the Proxy Statement would not include any misstatement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, the Party which discovers such information shall promptly notify the other Parties hereto and, to the extent required by applicable Law, an appropriate amendment or supplement describing such information shall be promptly filed by ARC with the SEC and disseminated by ARC to the stockholders of ARC. No filing of, or amendment or supplement to, the Proxy Statement will be made by ARC (including documents incorporated by reference therein) without providing the Buyer a reasonable opportunity to review and comment thereon; provided that with respect to documents that are incorporated by reference in the Proxy Statement, this right to review and comment shall apply only with respect to information relating to this Agreement or the transactions contemplated hereby or to Buyer or its Affiliates.

(b) Subject to the other provisions of this Agreement, ARC shall (i) take all action necessary in accordance with the Maryland General Corporation Law, its charter and bylaws and the rules of the New York Stock Exchange to duly call, give notice of, convene and hold a meeting of its stockholders as promptly as reasonably practicable following the mailing of the Proxy Statement for the purpose of obtaining the ARC Stockholder Approval (such meeting or any adjournment or postponement thereof, the “ARC Stockholder Meeting”), and (ii) subject to Section 5.5(d), recommend to its stockholders approval of the transactions contemplated by this Agreement (the “Recommendation”) and include such Recommendation in the Proxy Statement and use reasonable best efforts to solicit from its stockholders proxies in favor of the approval of the transactions contemplated by this Agreement. Notwithstanding anything in this Agreement to the contrary, unless this Agreement is terminated in accordance with Section 8.1 and subject to compliance with Section 8.2, ARC, regardless of whether the

Board of Directors has approved, endorsed or recommended an Alternative Proposal or has made a Change in Recommendation, will submit the Transactions for approval by the stockholders of ARC at the ARC Stockholder Meeting.

5.7 Employee Matters.

(a) (i) Not later than 10 days prior to the expected Closing Date, the Buyer shall offer employment to each Company Employee, which offer of employment shall be subject to the Closing occurring and shall include (A) a rate of base salary or wages equal to 100% of the rate of base salary or wages in effect with respect to such Company Employee immediately prior to the Closing Date and (B) amounts of cash incentive opportunities that are no less favorable than those in effect with respect to such Company Employee immediately prior to the Closing Date; provided that with respect to each such Company Employee who is an Inactive Employee as of the 10th day prior to the expected Closing Date, such offer shall be made by the Buyer only if such Seller Employee actually reports to employment with the Sellers on or prior to the date that is 90 days following the Closing Date (or such later period if required by Law) and is capable of performing his or her job duties as in effect immediately prior to the Closing Date with all accommodations, in which case such offer shall be made within one Business Day following the date on which such Company Employee so reports to employment. Each such Company Employee who accepts such offer of employment shall commence employment with the Buyer immediately following the Closing (or, in the case of such Inactive Employees, as of the date immediately following the date on which such employee accepts employment with the Buyer, if later) (as applicable, the “Employment Date,” and those Seller Employees who accept employment with the Buyer are referred to as “Continuing Employees”) and for all purposes consistent with Law and except as otherwise expressly provided herein such employment from and after the Employment Date, as applicable shall be deemed to have occurred with no interruption or break in service and no termination of employment. The Buyer shall not fire or otherwise discharge any Continuing Employees other than for cause until 45 days after the Closing Date.

(ii) On and as of the Closing Date, the Sellers shall provide such additional personnel information with respect to each Company Employee as may be reasonably requested by the Buyer; provided, however, that Sellers shall not be required to provide any information to the Buyer, the transmission of which would violate any Law regarding the transmission of personnel data, including the applicable provisions of the Health Insurance Portability Accountability Act of 1996, the Personal Information Protection and Electronic Documents Act and other legislation regulating the collection, use and disclosure of personal information, each as amended and the regulations promulgated thereunder.

(iii) The Sellers shall remain solely liable (including with respect to any severance costs and related liabilities) for any Company Employee who does not become a Continuing Employee and shall be solely liable with respect to an Inactive Employee for the period until such employee becomes a Continuing Employee, and the Buyer shall

have no liability with respect to any such employee. The Sellers shall use their reasonable efforts to encourage the Company Employees to accept the Buyer’s offers of employment.

(iv) The Sellers shall be solely responsible for all severance costs and related liabilities incurred by the Seller or the Buyer, as applicable, with respect to the termination of employment of Company Employees who do not accept the Buyer’s offer of employment made pursuant to this Section 5.7(a).

(b) For a period of no less than 12 months following the Closing Date (or, if shorter, the period of employment with the Buyer), the Buyer shall, and shall cause its Affiliates to, provide to the Continuing Employees employee benefits (including without limitation health and welfare, severance and retirement benefits) that are substantially similar in the aggregate to those provided to the Continuing Employees as of immediately prior to the Effective Time (excluding for this purpose equity-based incentive programs). Each Continuing Employee shall be given credit for all purposes (other than for benefit accrual for any defined benefit pension plan) for such person’s service with ARC and its Subsidiaries (or any other employer to the extent credited by ARC) to the same extent recognized by ARC under the Seller Plans prior to the Closing Date for all purposes under any analogous employee benefit plans, programs, policies or arrangements maintained by the Buyer or its affiliates (“Buyer Plans”) in which Continuing Employees participate following the Closing Date, except to the extent that giving such service credit would result in the duplication of benefits for the same period of service, and except under any defined benefit pension plan. The Buyer shall, and shall cause its Affiliates to, (i) waive (or, in the case of Insured Buyer Plans, use its commercially reasonable efforts to cause its third party insurance carriers to waive) all limitations as to preexisting conditions, exclusions and waiting periods and service requirements with respect to participation and coverage requirements applicable to the Continuing Employees under any Buyer Plan, other than limitations, exclusions, waiting periods or service requirements that are already in effect with respect to such persons and that have not been satisfied as of the Closing under any Seller Plan immediately prior to the Closing and (ii) provide (or, in the case of Insured Buyer Plans, use its commercially reasonable efforts to cause its third party insurance carriers to provide) each Continuing Employee with credit for any co-payments and deductibles paid prior to the Closing in satisfying any applicable deductible or out-of-pocket requirements for the plan year in which the Closing occurs under any analogous Buyer Plan.

(c) Effective as of the Effective Time, the Continuing Employees shall no longer actively participate in the ARC Management Services, Inc. 401(k) Plan (the “Sellers Savings Plan”). The Buyer shall designate a tax-qualified defined contribution plan (such plan, the “Buyer’s Savings Plan”) that permits the acceptance from Continuing Employees of “eligible rollover distributions” (as such term is defined under Section 402 of the Code). As soon as practicable following the Closing Date, (x) the Buyer shall provide ARC with such documents and other information as ARC shall reasonably request to assure itself that the Buyer’s Savings Plan is tax-qualified and provides for the receipt of eligible rollover

distributions and (y) ARC shall provide the Buyer with such documents and other information as the Buyer shall reasonably request to assure itself that the accounts of the Continuing Employees would qualify as eligible rollover distributions. Each Continuing Employee who is a participant in the Sellers Savings Plan shall be given the opportunity to receive a distribution of his or her account balance and shall be given the opportunity to elect a “direct rollover” in accordance with Section 401(a)(31) of the Code of the participant’s such account balance to the Buyer’s Savings Plan, subject to and in accordance with the provisions of such plan and applicable Law. ARC shall provide the Buyer with copies of such personnel and other records pertaining to the Continuing Employees and such records of any agent or representative of ARC pertaining to the Continuing Employees and such records of any agent or representative of ARC, in each case pertaining to the Sellers Savings Plan and as the Buyer may reasonably request in order to administer and manage the accounts and assets rolled over to the Buyer’s Savings Plan.

(d) As soon as reasonably practicable after the date hereof, but not later than ten Business Days following the date hereof, the Sellers shall deliver to the Buyer a true and complete list of all Company Employees and shall allow the Buyer to inspect the personnel files and other documentation relating to the Company Employees only to the extent legally permissible by applicable Law.

(e) No provision of this Section 5.7 shall be construed as (i) prohibiting Buyer and its Affiliates from terminating the employment of any Continuing Employee for any reason following the Closing Date, (ii) prohibiting the Buyer and its Affiliates from modifying or terminating any employee benefit plan, program agreement or arrangement in accordance with its terms and applicable Law or (iii) creating any third party beneficiary rights in any Continuing Employee.

(f) The Parties agree that the Sellers may award “Stay Bonuses” of up to $4 million to Company Employees between the date hereof and the Closing Date, provided that the identity of the recipients and the amount payable to each recipient shall be subject to the consent of the Buyer (such consent not to be unreasonably withheld). Any such Stay Bonus shall be payable by the Buyer upon the completion of 90 days following the Closing and shall not be paid to any Company Employee who does not accept an offer of employment by the Buyer or who terminates such Company Employee’s employment with the Buyer prior to 90 days following the Closing. The term “Stay Bonus Amount” means the amount by which the aggregate amount of Stay Bonuses paid to Company Employees exceeds the sum of (a) 50% of the aggregate amount of Stay Bonuses paid to Company Employees other than Company Employees that are employed at properties that are marketed by the Buyer pursuant to Section 5.4 plus (b) 100% of the aggregate amount of Stay Bonuses paid to Company Employees that are employed at properties that are marketed by the Buyer pursuant to Section 5.4.

5.8 Worker Notification.

(a) On or before the Closing, the Sellers shall provide a list of the name and site of employment of any Company Employees who have experienced, or will experience, an employment loss or layoff — as defined by the WARN Act or any similar applicable state or local law requiring notice to employees in the event of a closing or layoff — within ninety (90) days prior to the Closing. The Sellers shall update this list up to and including the Closing.

(b) The Buyer shall be responsible for compliance with the WARN Act with respect to the termination of any Company Employee occurring on or after the Closing.

5.9 Fees and Expenses.

(a) Buyer Expenses. Subject to Section 8.2 hereto, the Buyer shall pay all out-of pocket fees, costs and expenses, including fees and expenses of counsel, financial advisors, consultants and accountants, incurred by the Buyer incident to or in connection with the negotiation, preparation, execution, delivery and performance of this Agreement and the consummation of the transactions contemplated hereby, whether or not the Closing shall have occurred.

(b) Sellers’ and Acquired Companies’ Expenses. The Sellers shall pay all out-of-pocket fees, costs and expenses, including fees and expenses of counsel, financial advisors and accountants, incurred by the Sellers or the Acquired Companies incident to or in connection with the negotiation, preparation, execution, delivery and performance of this Agreement and the consummation of the transactions contemplated hereby, whether or not the Closing shall have occurred.

(c) Other Transaction Expenses. Notwithstanding anything to the contrary set forth in this Agreement, and without limiting any other provision herein allocating costs or other Liabilities to a Party hereunder, (i) the Buyer shall pay any out-of-pocket fees, costs and expenses incurred in connection with obtaining all Buyer Required Statutory Approvals, (ii) the Sellers shall pay any out-of-pocket fees, costs and expenses incurred in connection with obtaining all Seller Required Statutory Approvals, all Company Required Statutory Approvals, the Title Policies and the Consent Solicitations (in each case, other than the Parties’ legal fees and expenses which are the subject of Sections 5.9(a) and 5.9(b)) and (iii) the Buyer shall pay the filing fee in connection with any filings made under the HSR Act.

5.10 Further Assurances. Each of the Sellers, the Acquired Companies and the Buyer agree that, from time to time before and after the Closing Date, they will execute and deliver, or use reasonable best efforts to cause their other respective Affiliates to execute and deliver such further instruments, and take, or cause their respective Affiliates to take, such other action, as may be reasonably necessary to carry out the purposes and intents of this Agreement. From time to time after the Closing Date, each of the Sellers agrees to cooperate with Buyer upon the reasonable request of the Buyer in making available to the Buyer information in its possession relating to the conduct of the business of the Acquired Companies prior to the Closing; provided,

however, that the Sellers shall not be obligated to make any disclosure that (i) is prohibited by applicable Law, (ii) may cause any of the Sellers to breach a confidentiality obligation to which it is bound or (iii) would reasonably be expected to result in the loss of any applicable legal privilege.

5.11 Financing.

(a) Notwithstanding anything contained in this Agreement to the contrary, the Buyer expressly acknowledges and agrees that the Buyer’s obligations hereunder are not conditioned in any manner whatsoever upon the Buyer obtaining any financing. Upon request, the Buyer shall inform the Sellers of all material developments or changes relating to the Financing Commitment and the Financing contemplated thereby. The Buyer shall use commercially reasonable efforts to perform all obligations required to be performed by it in accordance with and pursuant to the terms of the Financing Commitments and to maintain such Financing Commitments in full force and effect in accordance with their terms, at all times prior to the Closing. In the event that the Financing Commitment shall cease to be in full force and effect at any time or the lenders or equity providers party thereto shall indicate any unwillingness to provide the Financing contemplated thereby, or for any reason the Buyer otherwise no longer believes in good faith that it will be able to obtain the Financing contemplated thereby, then the Buyer shall promptly notify the Sellers and use commercially reasonable efforts to obtain replacement financing arrangements or commitment letters as soon as reasonably practicable on terms no less favorable in the aggregate to the Buyer than those set forth in the Financing Commitments (including any market flex provisions therein).

(b) The Sellers agree to provide, and shall cause their Representatives to provide, reasonable cooperation (including with respect to timeliness) in connection with the arrangement of the Debt Financing as may be reasonably requested by the Buyer, including (i) participation in meetings, presentations, drafting sessions, due diligence sessions, “road shows” and sessions with rating agencies, (ii) furnishing the Buyer and its financing sources as promptly as practicable, in the ordinary course, with financial and other pertinent information regarding the Acquired Companies and the Acquired Business as may be reasonably requested by the Buyer, including all financial statements, financial data and other information (including with respect to the fiscal year ended December 31, 2006) (A) of the type required by Regulation S-X and Regulation S-K under the Securities Act and of type and form customarily included in private placements under Rule 144A of the Securities Act to consummate the offering of debt securities contemplated by the Financing Commitments at the time during ARC’s fiscal year such offerings will be made and (B) all financial statements and other information relating to the Acquired Companies and the Acquired Business necessary for the satisfaction of the conditions set forth in the Financing Commitments (collectively, the “Required Information”), (iii) reasonably assisting the Buyer and its financing sources in the preparation of (A) one or more offering documents and or confidential information memoranda for any portion of the Debt Financing and (B) materials for rating agency presentations, (iv) reasonably cooperating with the marketing efforts of the Buyer and its financing sources for any portion of the Debt Financing, including providing assistance in preparation for, and participating in, meetings, drafting sessions and due diligence sessions, (v) providing and executing documents as may be reasonably

The Sellers and the Buyer agree to issue a joint press release announcing the execution and delivery of this Agreement.

5.13 Indenture Consent Solicitation. Between the date hereof and the Closing Date, the Sellers shall use commercially reasonable efforts to amend the indenture governing ARC LP’s Senior Exchangeable Notes Due 2025 (the “Notes”) such that the transactions contemplated by this Agreement will be permitted under such indenture without Liability to the Buyer or any of its Subsidiaries (including the Acquired Companies and the Acquired Assets) from and after the Closing (the “Indenture Consent Solicitation”). The Sellers shall consult with the Buyer regarding the conduct of the Indenture Consent Solicitation and provide the Buyer with a reasonable opportunity to review and comment upon all documentation or public filings relating to the Indenture Consent Solicitation and such documentation and filings shall be reasonably acceptable to the Buyer to the extent affecting the Buyer, any Acquired Company or the Acquired Business after completion of the Transactions.

(ii) If (A) an Alternative Proposal that reasonably appears to be bona fide shall have been made known to ARC or shall have been made directly to its stockholders generally or any Person shall have publicly announced an intention (whether or not conditional or withdrawn) to make an Alternative Proposal that reasonably appears to be bona fide and thereafter and (B) this Agreement is terminated (x) by ARC or the Buyer pursuant to Section 8.1(b)(iii) (so long as the Alternative Proposal was publicly disclosed and not withdrawn at the time of ARC Stockholder Meeting) or (y) by ARC pursuant to Section 8.1(b)(i) (in each case, other than a termination giving rise to a right of Buyer to receive the Termination Fee pursuant to Section 8.2(a)(i)), then ARC shall pay to the Buyer the Buyer Expenses.

(iii) If, following a termination of this Agreement giving rise to an obligation of ARC to pay the Buyer Expenses pursuant to Section 8.2(a)(ii), ARC enters into a definitive agreement with respect to, or consummates, a transaction contemplated by any Alternative Proposal (provided that for purposes of this Section 8.2(a)(iii), the references to “20%” in the definition of Alternative Proposal shall be deemed to be references to “50%”) within twelve (12) months of the date this Agreement is terminated, then ARC will pay to the Buyer the Termination Fee.

(iv) For the avoidance of doubt, in no event shall ARC be required to pay the Termination Fee on more than one occasion.

(b) If this Agreement is terminated by ARC pursuant to Section 8.1(b)(i), Section 8.1(c)(i) or Section 8.1(c)(ii) and, at the time of termination, all the conditions set forth in Section 7.1 and 7.2 have been satisfied (other than any condition the failure of which to be satisfied has been proximately caused by the breach of this Agreement by the Buyer and conditions that, by their nature, are to be satisfied at Closing and which were, at the time of termination, capable of being satisfied), then:

(i) if, at the time of such termination, the lender under the Debt Financing Commitment has failed to fund the Debt Financing contemplated thereby, the Buyer shall pay to ARC a termination fee of $37.5 million (the “Debt Event Buyer Termination Fee”); or

(ii) if, at the time of such termination, the financing party under the Third Party Equity Commitment has failed to fund the Equity Financing contemplated thereby, the Buyer shall pay to ARC a termination fee of $50 million (the “Equity Event Buyer Termination Fee” and each of the Equity Event Buyer Termination Fee and the Debt Event Buyer Termination Fee being referred to as the “Buyer Termination Fee”).

(iii) For the avoidance of doubt, in no event shall the Buyer be required to pay both the Equity Event Buyer Termination Fee and the Debt Event Buyer Termination Fee or to pay a Buyer Termination Fee on more than one occasion, but if both the Equity Event Buyer Termination Fee and the Debt Event Buyer Termination Fee are due, then only the Equity Event Buyer Termination Fee shall be due.

(c) Any payment required to be made pursuant to Section 8.2(a)(iii) shall be made to the Buyer promptly following the earlier of the execution of a definitive agreement with respect to, or the consummation of, any transaction contemplated by an Alternative Proposal (and in any event not later than two Business Days after delivery to ARC of notice of demand for payment); any payment required to be made pursuant to Section 8.2(a)(i) or 8.2(a)(ii) shall be made to the Buyer promptly following the termination of this Agreement giving rise to such right to payment (and in any event not later than two Business Days after delivery to ARC of notice of demand for payment), and such payment shall be made by wire transfer of immediately available funds to an account to be designated by the Buyer. In circumstances in which Buyer Expenses are payable, such payment shall be made to the Buyer not later than two Business Days after delivery to ARC of an itemization setting forth in reasonable detail all Buyer Expenses (which itemization may be supplemented and updated from time to time by the Buyer until the 60th day after the Buyer delivers such notice of demand for payment), and all such payments shall be made by wire transfer of immediately available funds to an account to be designated by the Buyer. Any payment required to be made pursuant to Section 8.2(b) shall be made to ARC promptly following the termination of this Agreement by ARC giving rise to such right to payment (and in any event not later than two Business Days after delivery to the Buyer of notice of demand for payment), and such payment shall be made by wire transfer of immediately available funds to an account to be designated by ARC.

(d) In the event that ARC shall fail to pay the Termination Fee and/or Buyer Expenses, or the Buyer shall fail to pay the Buyer Termination Fee, required pursuant to this Section 8.2 when due, such fee and/or Buyer Expenses, as the case may be, shall accrue interest for the period commencing on the date such fee and/or Buyer Expenses, as the case may be, became past due, at a rate equal to the rate of interest publicly announced by Citibank, in the City of New York from time to time during such period, as such bank’s Prime Lending Rate (the “Prime Rate”). In addition, if either Party shall fail to pay such fee and/or Buyer Expenses, as the case may be, when due, the such owing Party shall also pay to the owed Party all of the owed Party’s costs and expenses (including attorneys’ fees) in connection with efforts to collect such fee and/or Buyer Expenses, as the case may be, the Buyer and ARC acknowledges that the fees, Buyer Expense reimbursement and the other provisions of this

Section 8.2 are an integral part of the Transaction and that, without these agreements, the Buyer and the Sellers would not enter into this Agreement.

(e) Each of the Parties hereto acknowledges that the agreements contained in this Section 8.2 are an integral part of the transactions contemplated by this Agreement and that none of the Termination Fee, the Buyer Termination Fee or the Buyer Expenses is a penalty, but rather is liquidated damages in a reasonable amount that will compensate the Buyer or ARC, as the case may be, for the efforts and resources expended and opportunities foregone while negotiating this Agreement and in reliance on this Agreement and on the expectation of the consummation of the transactions contemplated hereby, which amount would otherwise be impossible to calculate with precision. Notwithstanding anything to the contrary in this Agreement, but subject to the last sentence of this Section 8.2(e): (i) ARC’s right to receive payment of the Buyer Termination Fee pursuant to this Section 8.2 or the guarantee thereof pursuant to the Farallon Guarantee shall be the exclusive remedy of ARC against the Buyer, the Farallon Guarantor or any of their respective stockholders, partners, members, directors, Affiliates, officers or agents for (x) the loss suffered as a result of the failure of the Transaction to be consummated and (y) any other losses, damages, obligations or liabilities suffered as a result of or under this Agreement and the transactions contemplated hereby, and except with respect to payment of the Buyer Termination Fee in accordance with this Section 8.2, except as set forth in Section 8.2(d), neither the Buyer nor its stockholders, partners, members, directors, officers or agents, as the case may be, shall have any further liability or obligation relating to or arising out of this Agreement or the transactions contemplated by hereby (except that the Buyer also shall be obligated with respect to the provisions of this Section 8.2, it being understood that no other Person shall have any liability or obligation under or with respect to such provisions); and (ii) Buyer’s right to receive payment of the Termination Fee pursuant to this Section 8.2 shall be the exclusive remedy of the Buyer against the Sellers, the Acquired Companies or any of their respective stockholders, partners, members, directors, Affiliates, officers or agents for (x) the loss suffered as a result of the failure of the Transaction to be consummated and (y) any other losses, damages, obligations or liabilities suffered as a result of or under this Agreement and the transactions contemplated hereby, and except with respect to payment of he Termination Fee in accordance with this Section 8.2, except as set forth in Section 8.2(d), neither the Sellers, the Acquired Companies nor any of their Affiliates, stockholders, partners, members, directors, officers or agents, as the case may be, shall have any further liability or obligation relating to or arising out of this Agreement or the transactions contemplated hereby (except that the Sellers also shall be obligated with respect to the provisions of this Section 8.2, it being understood that no other Person shall have any liability or obligation under or with respect to such provisions). Notwithstanding the foregoing, and except as provided in, and subject to the limitations of, the Farallon Guarantee, the payment of the Termination Fee, the Buyer Termination Fee or the Buyer Expenses will not relieve any party hereto of liability for willful breach of any of the representations, warranties, covenants or agreements in this Agreement.

ARTICLE IX

INDEMNIFICATION

9.1 Indemnification by Sellers. From and after the Closing and subject to the provisions of this Article IX and Section 11.1, the Sellers jointly and severally agree to indemnify, defend and hold harmless the Buyer Indemnified Parties from and against any and all Liabilities, demands, claims, suits, actions, or causes of action, losses, costs, expenses, damages and judgments, whether or not resulting from third party claims, (including reasonable fees and expenses of attorneys and accountants and costs of investigation ) (collectively, “Damages”) incurred by any Buyer Indemnified Party and arising out of, relating to or resulting from (a) the failure of any representation or warranty set forth in Section 3.6 (Absence of Undisclosed Liabilities; Special Purpose Entities) (disregarding any materiality qualifier set forth in Section 3.6(a)) or 3.9 (Employee Benefit Plans; ERISA) to be true and correct as of the Effective Time with the same effect as though such representations and warranties had been made on and as of such time (except to the extent any such representation and warranty expressly speaks only as of a specific date, in which case as of such earlier date), (b) the failure of any representation or warranty set forth in Section 3.1(b), 3.1(c), 3.16(a) or 3.16(c) to be true and correct as of the Effective Time with the same effect as though such representations and warranties had been made on and as of such time (except to the extent any such representation and warranty expressly speaks only as of a specific date, in which case as of such earlier date), (c) any breach of any covenant or agreement of any Seller set forth in Article I or of any covenant or agreement of any Seller set forth in this Agreement that contemplates or provides for any rights, obligations or actions of any Party after the Closing or (d) any Excluded Liability.

9.2 Indemnification by the Buyer. From and after the Closing and subject to the provisions of this Article IX and Section 11.1, the Buyer agrees to indemnify, defend and hold harmless the Seller Indemnified Parties, from and against any and all Damages incurred by any Seller Indemnified Party arising out of, relating to, or resulting from (a) any breach of any covenant or agreement of the Buyer set forth in Article I or of any covenant or agreement of the Buyer set forth in this Agreement that contemplates or provides for any rights, obligations or actions of any Party after the Closing, (b) any Assumed Liability or (c) the business and operation of the Acquired Assets, the Acquired Companies and the Acquired Business, whether arising out of or relating to conduct occurring prior to, on or after the Closing, other than items for which indemnification is or would be provided by the Sellers under this Agreement.

9.3 Indemnification Process.

(a) A party making a claim for indemnification under this Article IX shall be, for the purposes of this Agreement, referred to as an “Indemnified Party” and a party against whom such claims are asserted under this Article IX shall be, for the purposes of this Agreement, referred to as an “Indemnifying Party.” All claims by any Indemnified Party under this Article IX shall be asserted and resolved as follows:

(b) In the event that (i) any action, application, suit, demand, claim or legal, administrative, arbitration or other alternative dispute resolution proceeding, hearing or investigation (each, a “Proceeding”) is asserted or instituted by any Person other than the Parties or their Affiliates which could give rise to Damages for which an Indemnifying Party could be liable to an Indemnified Party under this Agreement (such Proceeding, a “Third Party Claim”) or (ii) any Indemnified Party under this Agreement shall have a claim to be indemnified by any Indemnifying Party under this Agreement which does not involve a Third Party Claim (such claim, a “Direct Claim” and, together with Third Party Claims, “Claims”), the Indemnified Party shall, promptly after it becomes aware of a Third Party Claim, or determines that there exists a reasonable basis for a Direct Claim, send to the Indemnifying Party a written notice specifying the nature of such Claim and the amount or estimated amount thereof (which amount or estimated amount shall be made without prejudice to the parties’ rights and shall not be conclusive of the final amount, if any, of such Claim) (a “Claim Notice”), together with copies of all notices and documents (including court papers) served on or received by the Indemnified Party in the case of a Third Party Claim, provided that a delay in notifying the Indemnifying Party shall not relieve the Indemnifying Party of its obligations under this Article IX except to the extent of any incremental damage or liability the Indemnifying Party shall have incurred as a result of such failure to give such notice, in which case the Indemnifying Party shall be relieved of its obligations under this Article IX to the extent of such incremental damage or liability.

(c) In the event of a Third Party Claim, the Indemnifying Party shall have the right to defend the Indemnified Party against such Third Party Claim and be entitled to appoint counsel of the Indemnifying Party’s choice (but reasonably acceptable to the Indemnified Party) at the expense of the Indemnifying Party to represent the Indemnified Party in connection with such Proceeding; provided that the Indemnifying Party shall not be entitled to assume or continue control of the defense of any Third Party Claim if (i) the Third Party Claim relates to or arises in connection with any criminal proceeding, action, indictment, allegation or investigation, (ii) the Third Party Claim seeks an injunction or equitable relief against any Indemnified Party, (iii) the Third Party Claim, if determined in favor of the claimant, would result in Damages in excess of the amounts available for indemnification pursuant to this Article IX or (iv) the Indemnified Party has not, prior to the assumption of such defense, acknowledged that such Third Party Claim is subject to indemnification under this Article IX. If the Indemnifying Party assumes the defense of a Third Party Claim, the Indemnified Party may retain separate counsel in connection with such Third Party Claim, but the Indemnifying Party shall bear the reasonable fees, costs and expenses of such separate counsel only if (i) the use of counsel selected by the Indemnifying Party to represent the Indemnified Party would present such counsel with a conflict of interest or (ii) the Indemnifying Party shall not have engaged counsel to represent the Indemnified Party within a reasonable time after notice of the institution of such Third Party Claim. Nothing in this Section 9.3(c) shall require the Indemnifying Party to be responsible for the fees and expenses of more than one counsel (in addition to any local counsel) at any time in connection with the defense against a Third Party Claim. If requested by the Indemnifying Party, the Indemnified Party agrees to reasonably cooperate with the Indemnifying Party and its counsel in defending and contesting any Proceeding which the Indemnifying Party defends, or, if appropriate and related to the Proceeding in question, in making any counterclaim against the person asserting

the Third Party Claim, or any cross-complaint against any Person. No Third Party Claim may be settled or compromised (i) by the Indemnified Party without the prior written consent of the Indemnifying Party (which consent shall not be unreasonably withheld or delayed) or (ii) by the Indemnifying Party without the prior written consent of the Indemnified Party (which consent shall not be unreasonably withheld or delayed), unless, in the case of this clause (ii), the sole relief provided is monetary damages that are paid in full by the Indemnifying Party and such settlement provides for a full release of all Liability of the Indemnified Party in respect of such Third Party Claim; provided that, in no event will the Indemnifying Party be permitted to settle any Third Party Claim for which the Indemnifying Party would not be entitled to assume the defense hereunder, without the prior written consent of the Indemnified Party. In the event any Indemnified Party settles or compromises or consents to the entry of any judgment with respect to any Third Party Claim without the prior written consent of the Indemnifying Party (except in the event the Indemnifying Party unreasonably withheld or delayed its consent), such Indemnified Party shall be deemed to have waived all rights against the Indemnifying Party for indemnification under this Article IX with respect to such Third Party Claim.

9.4 Limitations on Claims.

(a) Liability Threshold for Buyer Indemnified Parties. Notwithstanding anything in this Article IX to the contrary, no Buyer Indemnified Party shall be entitled to indemnification pursuant to Section 9.1(a), unless and until the aggregate amount of Damages incurred by such party for which indemnification is available under Section 9.1(a), exceeds an amount equal to $10,000,000 (the “Liability Threshold”), and then, subject to Section 9.4(b), the Buyer Indemnified Parties shall be entitled to the benefit of the indemnity under Section 9.1(a) only for the portion of any and all Damages that exceed the Liability Threshold.

(b) Maximum Liability. Notwithstanding anything in this Article IX to the contrary, the aggregate amount of the Sellers’ liability pursuant to Section 9.1(a) shall not exceed $100,000,000.

(i) The amount of any Damages incurred by the Indemnified Party shall be reduced by the net amount the Indemnified Party or any of its Affiliates recovers (after deducting all attorneys’ fees, expenses and other costs of recovery) from any insurer or other party liable for such Damages (other than any Seller). The Indemnified Party shall use commercially reasonable efforts to effect any such recovery.

(ii) Any liability for indemnification under this Agreement shall be determined without duplication of recovery by reason of the state of facts giving rise to such liability constituting a breach of more than one representation, warranty, covenant or agreement.

(d) Exclusive Remedy. Except to the extent provided in Article VI, from and after the Closing, the indemnities provided for in this Article IX shall be the exclusive remedies of the Parties and their respective officers, directors, employees, Affiliates, agents, representatives, successors and assigns for money damages in respect of any breach of or inaccuracy in any representation or warranty or breach of or noncompliance with any covenant or agreement contained in this Agreement and the Parties shall not be entitled to a rescission of this Agreement or to any further indemnification or other rights or claims for money damages in respect thereof, all of which the Parties hereto hereby waive; provided, however, that the foregoing shall not limit the right of any party to assert a claim based on fraud.

9.5 Characterization of Indemnification Payments. The Buyer and the Sellers agree to treat any indemnification payment made under this Agreement, to the maximum extent permitted by applicable Law, as an adjustment to the Final Purchase Price.

9.6 Limitation on Damages. No Party shall, under any circumstance, except to the extent imposed by any Third Party Claim, have any liability to any other Party for any special, indirect, consequential or punitive damages claimed by such other Party under the terms of or due to any breach or non-performance of this Agreement, including lost profits, loss of revenue or income, cost of capital, or loss of business reputation or opportunity.

9.7 No Other Indemnification. For the avoidance of doubt, no Party shall have any indemnification obligations to any other party in respect of this Agreement or the transactions contemplated hereby except as set for in Section 6.1, Section 9.1 or Section 9.2 of this Agreement.

11.4 Assignment; Successors; Third-Party Beneficiaries; Obligations. This Agreement is not assignable (including by operation of law) by any Party without the prior written consent of all of the other Parties and any attempt to assign this Agreement without such consent shall be void and of no effect. Notwithstanding the foregoing, without the prior written consent of the Sellers, the Buyer and its permitted assigns may at any time, in its sole discretion, assign, in whole or in part, (a) its rights and obligations pursuant to this Agreement, to one or more of its Affiliates, or (b) its rights under this Agreement, in each case, for collateral security purposes to any lender providing financing to the Buyer or lessor pursuant to a lease financing transaction, and any such lender or lessor (or collateral agent acting on its behalf) may exercise all of the rights and remedies of the Buyer hereunder and thereunder, and the Sellers agree to, and shall cause its Affiliates to, execute and deliver a consent in favor of such lenders or lessors (or collateral agent acting on their behalf) with respect to the collateral assignments contemplated by this Section 11.4 in form and substance reasonably satisfactory to the Sellers and containing customary and reasonable provisions for similar nonrecourse financings.

The obligators of each Seller hereunder shall be joint and several obligations among the Sellers.

11.5 Amendment; Waivers; Etc. No amendment, modification or discharge of this Agreement, and no waiver under this Agreement, shall be valid or binding unless set forth in writing and duly executed by the Party against whom enforcement of the amendment, modification, discharge or waiver is sought; provided that any such amendment, modification, discharge or waiver will be effective against each Seller if executed by ARC. Any such waiver shall constitute a waiver only with respect to the specific matter described in such writing and shall in no way impair the rights of the Party granting such waiver in any other respect or at any other time. No waiver by any of the Parties of a breach of or a default under any of the provisions of this Agreement, in any one or more instances, shall be deemed to be or construed as a waiver of the same or any other term or condition of this Agreement on any future occasion. No failure or delay to exercise any right, power or privilege under this Agreement shall be construed as a waiver thereof.

11.6 Entire Agreement. This Agreement (including the Buyer Disclosure Letter and Sellers Disclosure Letter and Exhibits referred to in or delivered under this Agreement) and the Confidentiality Agreement constitute the entire agreement and supersede all prior agreements and understandings, both written and oral, among the Parties with respect to their subject matters.

Items disclosed on one particular section of the Sellers Disclosure Letter or the Buyer Disclosure Letter relating to one section of this Agreement shall be deemed to be constructively disclosed or listed in other sections of the Sellers Disclosure Letter or the Buyer Disclosure Letter, as the case may be, relating to other sections of this Agreement only to the extent it is reasonably apparent on the face of such other sections of the Sellers Disclosure Letter or the Buyer Disclosure Letter that such disclosure is applicable to such other sections of the Sellers Disclosure Letter or the Buyer Disclosure Letter, as the case may be. The fact that

any item of information is contained in any disclosure letter shall not be construed as an admission of liability under any applicable Law, or to mean that such information is required to be disclosed in or by this Agreement, or to mean that such information is Material. Such information shall not be used as a basis for interpreting the term “Material,” “material,” “materially,” “materiality,” “Company Material Adverse Effect,” or any similar qualification in this Agreement.

11.8 Severability. Any term or provision of this Agreement that is held by a court of competent jurisdiction or other authority to be invalid, void or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction. If the final judgment of a court of competent jurisdiction or other authority declares that any term or provision hereof is invalid, void or unenforceable, the Parties agree that the court making such determination, to the greatest extent legally permissible, shall have the power to reduce the scope, duration, area or applicability of the term or provision, to delete specific words or phrases, or to replace any invalid, void or unenforceable term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision.

11.10 Governing Law. THIS AGREEMENT SHALL BE CONSTRUED, PERFORMED AND ENFORCED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT GIVING EFFECT TO ITS PRINCIPLES OR RULES OF CONFLICT OF LAWS (OTHER THAN SECTION 5-1401 OF THE GENERAL OBLIGATIONS LAW OF THE STATE OF NEW YORK).

Process in any such suit, action or proceeding may be served on any party anywhere in the world, whether within or without the jurisdiction of any such court. Without limiting the foregoing, each party agrees that service of process on such party as provided in Section 11.2 shall be deemed effective service of process on such party.

11.12 Waiver of Jury Trial; Waiver of Immunity.

(b) Each Party agrees that in any legal action or proceeding against it or its assets in connection with this Agreement, no immunity from such legal action or proceedings (which shall include suit, attachment prior to judgment, other attachment, the obtaining of judgment, execution or other enforcement) shall be claimed by or on behalf of it or with respect to its assets, irrevocably waives any such right of immunity which it or its assets now have or may hereafter acquire or which may be attributed to it or its assets and consents generally in respect of such legal action or proceedings to the giving of any relief or the issue of any process in connection with such action or proceedings including the making, enforcement or execution against any property whatsoever (irrespective of its use or intended use) of any order of judgment which may be made or given in such action or proceedings.

11.13 Enforcement. The Parties agree that irreparable damage would occur to Buyer in the event that any of the provisions of this Agreement were not to be performed by the Sellers in accordance with the specific terms hereof or was otherwise breached and that Buyer shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically performance the terms hereof in addition to any other remedies at law or in equity. The Parties acknowledge that the Sellers shall not be entitled to an injunction or injunctions to prevent breaches of this Agreement by Buyer or to enforce specifically the terms and provisions of this Agreement and that the Sellers’ sole and exclusive remedy with respect to any such breach shall be the remedy set forth in Section 8.2. The Sellers agrees that, notwithstanding anything herein to the contrary, and except as explicitly provided in the Farallon Guarantee,(i) to the extent it has incurred losses or damages arising out of the breach of this Agreement by the Buyer, (A) the maximum aggregate liability for such losses or damages shall be limited to the sum of the Buyer Termination Fee and the amount of interest accrued thereon, if any, pursuant to Section 8.2(d), (B) in no event shall the Sellers seek to recover any money damages in excess of such amount from Buyer and the Farallon Guarantor, and (C) the maximum liability of the Farallon Guarantor, directly or indirectly, shall be limited to the express obligations of the Farallon Guarantor under the Farallon Guarantee, and (ii) in no event shall any Non-Recourse Party (as defined in the Farallon Guarantee) have any liability or obligation relating to or arising out of this Agreement or the transactions contemplated hereby.
