(m) any Liability of any Non-Seller Subsidiary (as defined in Section 2.1(b)); and

1.5 Consideration.

(a) Closing Payment. As consideration in full for the acquisition of the Assets from Sellers, Buyer is assuming the Assumed Liabilities, and Buyer is paying Sellers the aggregate sum of $55,805,000 plus the allowance (the “Severance Allowance”) set forth in Section 1.5(b) (collectively, the “Purchase Price”), to be paid at Closing by wire transfer of immediately available funds to the account or accounts specified in Schedule 1.5(a) (which Sellers will provide at least 3 days before the Closing Date). Parent guarantees the payments of any amounts owed by Buyer and any performance of Buyer’s obligations under this Agreement.

(b) Severance Allowance. At the Closing, as part of its certificate delivered pursuant to Section 5.1(s), Citadel will certify (for which certification Citadel may rely, in part, on Parent’s delivery of an updated Schedule 4.9(a) at Closing) as to: (A) which employees of each Seller are Non-Transferred Employees (as defined in Section 4.9(a)), and (B) the aggregate change of control, severance, tax gross-up, option exercise price payments and other termination payments any Citadel Party will be obligated to pay such Non-Transferred Employees upon consummation of the transactions contemplated herein (“Change of Control Payments”). As part of the Purchase Price, Buyer will pay the lesser of the Change of Control Payments and $345,000. Notwithstanding the foregoing, (i) Buyer will not be required to make any payment with respect to a Non-Transferred Employee unless such Non-Transferred Employee is listed on Schedule 1.5(b) and (ii) the amount allocated to any individual Non-Transferred Employee will not exceed the amount set forth opposite such individual’s name on Schedule 1.5(b).

(i) At least seven days prior to the Closing, Sellers will provide Parent with Sellers’ estimate of the Op Ex Amount (as defined below) and the Cash Amount (as defined below) (the “Initial Estimate”). Included as part of the Initial Estimate will be (A) a detailed description of all cash, check, wire transfer or similar receipts or other payments (“Cash Payments”) and related Cash Amounts (as defined below) received by a Seller between August 1, 2006 and the Closing Date (estimated for the two weeks that precede the Closing Date), (B) a calculation of the Op Ex Amount, (C) a calculation of the Op Ex Reimbursement (as defined below), (D) an indication on a detailed basis whether such payments should be included in the Cash Amount or not, (E) an indication whether any such Cash Payment was made in respect of a Factored Account (as defined below), and, if so, an explanation for the basis of the calculation of the related Cash Amount, and (F) for all such Cash Payments that are not included in the Cash Amount, an explanation for why such Cash Payments should be so excluded.

(ii) On the Closing Date, the Sellers will provide Parent with (x) an update of the Initial Estimate through the Closing Date, which will include an update of the matters identified in Section 1.5(c)(i)(A)-(F) through the Closing Date (the “Final Estimate”), and, (y) attached thereto, a certification, signed by a

senior officer of Citadel, that to the Knowledge (as defined in Section 9.13(d)) of the Citadel Parties such Final Estimate is true and correct in all respects.

(iii) If the Cash Amount exceeds the Op Ex Amount, then Citadel shall as promptly as is commercially reasonable pay Buyer an amount equal to the difference between the Cash Amount and the Op Ex Amount. If the Op Ex Amount exceeds the Cash Amount, Buyer shall pay Sellers an aggregate amount equal to the difference between the Op Ex Amount and the Cash Amount (the “Op Ex Reimbursement”).

(iv) If (x) the Final Estimate shows that there is an Op Ex Reimbursement, (y) Sellers have complied with Section 1.5(c)(i)-(ii) and (z) the Citadel CEO executes and delivers to Buyer and Parent a Guaranty of payment in the form attached hereto as Exhibit F (the “Guaranty”), then Buyer shall make such payment within five days of (A) the delivery to Parent of the Final Estimate, in final complete form, (B) the delivery to Parent of the related certification described in Section 1.5(c)(ii) and (C) the execution and delivery to Parent and Buyer of the Guaranty by the Citadel CEO; provided, however, if, as a result of the progress of Parent’s Audit (as defined below) through the date such payment is due, Parent believes that the Op Ex Reimbursement set forth in the Final Estimate is inaccurate, Buyer shall be entitled to reduce such payment by the amount of such inaccuracy. If the conditions set forth in this Section 1.5(c)(iv) are not met, Buyer shall make such payment as promptly as is commercially reasonable upon completion of the Audit (as defined in below) (and subject to the conclusions of such Audit). If the Op Ex Reimbursement is made before the completion of the Audit, it is referred to herein as the “Estimated Op Ex Reimbursement Payment.”

(v) Following the Closing, Parent will conduct an audit to determine the Op Ex Amount, the Cash Amount and the Op Ex Reimbursement (if any) (the “Audit”). Each Citadel Party agrees to cooperate in all respects with the Audit and to provide any information that Parent requests in connection with the Audit, and if the Citadel Parties so cooperate and provide such information promptly, Parent will complete the Audit within 30 days following the Closing Date. Upon completion of the Audit, Parent will promptly deliver to Citadel a summary of the Audit, including detail regarding Parent’s determination of the Op Ex Reimbursement and Parent’s assessment of the determinations set forth in the Final Estimate. The Citadel Parties shall have five (5) business days (excluding the day received) to object in writing to the results of the Audit which objection must specify the nature of the objection in detail, and if no such objection is made, the results of the Audit shall be deemed accepted by all Seller Parties and shall be, absent manifest error, binding upon the parties. If the Citadel Parties object to the results of the Audit, Citadel and Parent shall attempt in good faith to resolve any objection within 5-business days. In the event the parties are unable to resolve their differences within said 5-business day period, Parent shall select a firm of certified public accountants reasonably acceptable to Citadel (which shall be one of ▇▇▇▇▇ ▇▇▇▇▇▇▇▇ LLP or BDO ▇▇▇▇▇▇▇, LLP) to determine the Op Ex

Amount, the Cash Amount and the Op Ex Reimbursement (if any), whose determination shall be, absent manifest error, final and binding on the parties (such arbitration is the “Op Ex Arbitration”). Each of Parent and Citadel shall pay one-half of the costs of the Op Ex Arbitration.

(vi) If (x) Citadel has made a payment pursuant to Section 1.5(c)(iii), and (y) following the Audit (or the Op Ex Arbitration, if applicable), Parent concludes that Citadel did not pay the correct amount, then (A) if Citadel paid Parent a greater amount than Parent concludes was required, Parent shall pay Citadel the difference promptly, and (B) if Citadel paid Parent a lesser amount than Parent concludes was required, Citadel shall pay Buyer the difference promptly upon receipt of notice thereof.

(vii) If an Estimated Op Ex Reimbursement Payment made pursuant to Section 1.5(c)(iv) is more than the Op Ex Reimbursement, as determined by Parent in connection with the Audit (or as determined in connection with the Op Ex Arbitration, if applicable), then Parent will give notice of such shortfall (the “Op Ex Shortfall”) to the Citadel Parties. The Citadel Parties agree, jointly and severally, to reimburse Buyer for the Op Ex Shortfall within 3 days of receipt of such notice. If Buyer does not receive such payment within such 3-day period, Buyer may collect the Op Ex Shortfall pursuant to the Guaranty, and if Buyer does receive such payment within such 3-day period, the Guaranty will terminate. In addition, if within 10 days following completion of the Audit (or within 10 days following completion of the Op Ex Arbitration, if applicable), Parent does not deliver notice of an Op Ex Shortfall to the Citadel Parties, then the Guaranty will terminate.

(viii) “Op Ex Amount” shall mean the amount determined by: (1) multiplying the number of full calendar months that elapse between August 1, 2006 and the Closing Date by $1.7 million and (2) adding a pro-rated portion of $1.7 million based upon the number of days elapsed in the calendar month during which the Closing occurs through the day immediately before the Closing Date divided by the total number of days in such calendar month.

(ix) “Cash Amount” shall mean an amount equal to the aggregate dollar amount of any Cash Payments received by a Citadel Party from any direct or indirect customer ▇▇▇▇▇▇▇▇ and invoices between August 1, 2006 and the Closing Date; provided, however, for any cash received with respect to a Factored Account (as defined below), the amount credited as a Cash Amount for purposes hereof shall be the face amount of the Factored Account (and not the lesser amount of cash received from the Factor). “Factored Accounts” are accounts receivable or other ▇▇▇▇▇▇▇▇ factored or sold pursuant to the Factoring Agreement.

(x) Each Seller hereby represents that it has billed and invoiced during the period from July 1, 2006 until August 1, 2006 in a manner consistent with its historical practices.

1.6 Closing. The closing (the “Closing”) of the transactions contemplated by this Agreement shall take place at the offices of ▇▇▇▇▇▇ & ▇▇▇▇ LLP, ▇▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇, or via Federal Express, emailed pdf signature pages and/or facsimile, as agreed by the parties, at 10:00 a.m. local time on the first business day that is commercially practicable after all conditions to Closing have been satisfied or waived in writing, but in any case, provided such conditions have been satisfied, no later than five business days following the completion of the Stockholder Approval (as defined in Section 5.1(i)) at the Citadel Stockholders’ Meeting (as defined in Section 4.12(a)) (such date and time of closing being herein called the “Closing Date”). The Closing will be deemed to be effective for purposes of this Agreement as of 10:00 a.m. local time on the Closing Date (the “Effective Time”).

1.7 Closing Deliveries. At the Closing,

(a) Buyers will pay the Purchase Price to Sellers;

(b) Sellers will endorse and deliver to Buyer any certificates of title necessary to effect or record the transfer of any Assets for which ownership is evidenced by a certificate of title (each of which is listed on Schedule 1.7(b));

(l) Sellers will deliver to Buyer the originals or copies of all of Sellers’ books, records, ledgers, disks, proprietary information and other data included within the Assets and all other written or electronic depositories of information relating to the Assets and the Business, including a “snap shot” copy in a format reasonably requested by Buyer of all data stored by Sellers using Sellers’ Softrax software; and

(m) the Buyers and the Sellers will execute and deliver the documents required to be delivered by each of them pursuant to Article V.

1.8 Further Assurances. At or after the Closing, and without further consideration, the Sellers will execute and deliver to Buyer such further instruments of conveyance and transfer, and take such other action, as Buyer may reasonably request in order more effectively to convey and transfer the Assets to Buyer and to put Buyer in operational control of the Assets and the Business, for aiding, assisting, collecting and reducing to possession any of the Assets and exercising rights with respect thereto or for fulfilling the obligations of the Sellers pursuant to Section 4.10.

1.9 Allocation of Purchase Price. Within 20 days after the Closing Date, Buyer will provide to the Sellers a proposed allocation of the Purchase Price. If the Sellers disagree with any aspect of the proposed allocation, the Sellers shall, within 15 days after receipt thereof, furnish to Buyer a written statement of such disagreement, together with the reasons therefor. If, within such 15 day period, Buyer does not receive such a written statement of disagreement from the Sellers, the Sellers shall be deemed to have accepted the proposed allocation and the proposed allocation shall be final and binding upon the Sellers. If Buyer does receive such a written statement of disagreement from the Sellers within such 15 day period, then within 10 days of such receipt the Sellers and Buyer shall discuss in person, by telephone, or by videoconference, their disagreement in order to attempt to resolve it through good faith negotiations. If the Sellers and Buyer are unable to resolve their disagreement within 20 days after receipt by Buyer of the written statement of disagreement from the Sellers, the disagreement shall be submitted for determination to a mutually agreed upon independent nationally recognized accounting firm (the “Accountant”), which determination, absent manifest error, shall be final and binding upon the Sellers and Buyer and not subject to appeal.

Except as set forth in the Schedules in a response that corresponds to the Section numbers identified below, each of the Citadel Parties hereby jointly and severally represents and warrants to Buyer as follows as of the date hereof and, by delivery of the certificate identified in Section 5.1(s), as of the date of Closing:

Citadel Sub is a Delaware limited liability company duly organized, validly existing and in good standing under the laws of the State of Delaware. Canberra LLC is a Delaware limited liability company duly organized, validly existing and in good standing under the laws of the State of Delaware, and Canberra LP is a Texas limited partnership duly organized, validly existing and in good standing under the laws of the State of Texas. Canberra LLC owns no assets (other than limited partnership interest in Canberra LP) and operates no business other than the ownership of such interest. Citadel owns, directly or indirectly, all of the outstanding equity, membership and voting interests in each Seller and in Canberra LLC. Each of the Citadel Parties has full power to own its properties and to conduct its business as presently conducted. Each of the Sellers, Canberra LLC and each of the Non-Seller Subsidiaries (as defined in Section 2.1(b)) (collectively, the “Citadel Entities”) is duly authorized, qualified or licensed to do business and is in good standing in each state or other jurisdiction in which the Business as presently conducted makes such qualification necessary except where the failure to be so qualified would not, individually or in the aggregate, constitute a Material Adverse Change (as defined in Section 2.7(a)) or a Material Event (as defined below). Each Citadel Party is required to be qualified to do business as a foreign entity in the jurisdictions set forth in Schedule 2.1, and each Citadel Party is so qualified in such applicable jurisdictions except where the failure to be so qualified would not, individually or in the aggregate, constitute a Material Adverse Change or a Material Event. Set forth in Schedule 2.1 is a list of all assumed names, DBAs or fictitious names under which each Citadel Entity operates and all jurisdictions in which any of such assumed names is registered. “Material Event,” for purposes of this Agreement, means any event, action or omission that (i) has resulted in (or can reasonably be expected to result in) damage to, or reduction of value in, the Assets or the Business that exceeds $30,000, (ii) that requires the consent, authorization or approval of a third party or Governmental Body (as defined in Section 2.5), in connection with the transactions contemplated hereby, that, but for such event, action or omission, would not have been required, or (iii) that materially and adversely affects (or can reasonably be expected to materially and adversely affect) Seller’s ownership of or rights in the Seller Intellectual Property.

(b) Other than Citadel Sub, Canberra LP and Canberra LLC, the following are the only direct or indirect subsidiaries of Citadel: ▇▇▇▇-▇▇▇▇▇ Ltd., Inc., a Texas Corporation; Astonishing Developments, Inc., a Texas corporation; Danasoft, Inc., a Delaware corporation; and Citadel Computer Systems Acquisition, Inc. (f/k/a LSHC Acquisition

Corp.), a Delaware corporation (the “Non-Seller Subsidiaries”), and no Seller has any other subsidiaries or owns any direct or indirect equity or debt interest or any form of proprietary interest in any other Person, or any obligation, right or option to acquire (including by conversion) any such interest.

2.2 Authority.

(a) Each Citadel Party has all requisite power, authority and capacity to execute, deliver and perform under this Agreement and the other agreements, certificates and instruments to be executed by such Citadel Party in connection with or pursuant to this Agreement (collectively, the “Seller Documents”). Subject only to the approval of the Stockholder Approval Matters (as defined in Section 4.11(a)) by the stockholders of Citadel as described in Section 2.2(b), the execution, delivery and performance by each Seller of each Seller Document to which it is a party has been duly authorized by all necessary action on the part of such Seller. In connection with the foregoing, the Board of Directors of Citadel has unanimously, as of the date hereof (i) determined that this Agreement and the transactions contemplated by this Agreement are advisable and in the best interests of Citadel and its stockholders, and (ii) adopted this Agreement in accordance with the provisions of applicable Law and Citadel’s certificate of incorporation and bylaws. This Agreement has been, and at the Closing the other Seller Documents will be, duly executed and delivered by each Citadel Party (to the extent each is a party thereto). This Agreement is, and, upon execution and delivery at the Closing, each of the other Seller Documents will be a legal, valid and binding agreement of each Citadel Party (to the extent it is a party thereto), enforceable against each Citadel Party in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, fraudulent conveyance or similar laws affecting the enforcement of creditors’ rights generally and subject to general principles of equity (regardless of whether enforcement is sought in a proceeding of law or in equity).

(b) The affirmative vote of the holders of at least a majority of the outstanding shares of Citadel’s common stock are the only votes of holders of any shares of the capital stock of Citadel necessary to approve the Stockholder Approval Matters at the Citadel Stockholders’ Meeting (as defined in Section 4.12(a)).

2.3 Title to Assets.

(a) (i) Set forth in Schedule 2.3(a)(i) is a complete list of each tangible Asset of any Seller; and (ii) set forth on Schedule 2.3(a)(ii) is a complete and detailed list of the street address of all real property leased by any Seller or otherwise used in connection with the Business (the “Real Property”) along with the rent obligations over the terms of the underlying leases and the leasehold improvements associated with each piece of such Real Property. Set forth in Schedule 2.3(a)(iii) is a list of all of the assets of Sellers other than the Assets (collectively, the “Excluded Assets”). The Assets, together with the Excluded Assets, constitute all of the assets of Sellers that are used in, generated by or associated with the Business. The Assets, together with the Excluded Assets, constitute all assets necessary to carry on the Business as currently conducted. No Non-Seller Subsidiary has any customers, owns any license, intellectual property, permit, material

asset or any asset used in, generated by or associated with the Business. No Non-Seller Subsidiary is a party to or a beneficiary of any material agreement or any agreement related to or associated with the Business. Substantially all of the assets (tangible and intangible) of each of the Non-Seller Subsidiaries were validly transferred to Citadel effective in May 2002. No Citadel Entity owns any real property, nor has any Citadel Entity ever owned any real property. No Citadel Entity owns or leases any motor vehicles.

(b) Each Citadel Party has good and marketable title to all of the Assets it owns, or purports to own, and a valid leasehold interest in all leased assets included within the Assets, free and clear of any Liens (as defined in Section 9.13(g)), other than Permitted Liens (as defined in Section 9.13(j)). The execution and delivery of the Seller Documents by the Sellers at the Closing will convey to and vest in Buyer good and marketable title to the Assets, free and clear of any Liens. The Assets, including any Assets held under leases or licenses: (i) are in good condition and repair, ordinary wear and tear excepted; and (ii) are in good working order and have been properly and regularly maintained. There is no default by any Citadel Entity or, to the Knowledge of the Citadel Parties, any landlord under any lease of the Real Property, and to the Knowledge of the Citadel Parties, no event has occurred and no condition exists which, with notice or given the passage of time, or both, would constitute a default by any party under such leases.

2.4 No Violation. Except as described in Schedule 2.4, neither the execution or delivery of the Seller Documents nor the consummation of the transactions contemplated thereby, including the sale of the Assets to Buyer, will conflict with or result in the breach of any term or provision of, require consent or violate or constitute a default under (or an event that with notice or lapse of time or both would constitute a breach or default), or result in the creation of any Lien on the Assets pursuant to, or relieve any Person of any obligation to any Citadel Entity or give any Person the right to terminate or accelerate any obligation under, any charter provision, bylaw, Permit (as defined in Section 2.11) or Law to which any Citadel Entity is a party or by which any Citadel Entity or any of the Assets or the Business is in any way bound or obligated.

2.5 Governmental Consents. No consent, approval, order or authorization of, or registration, qualification, designation, declaration or filing with, any governmental or quasi-governmental agency, authority, commission, board or other body (collectively, a “Governmental Body”) is required on the part of any Citadel Entity in connection with the sale and purchase of the Assets or any of the other transactions contemplated by this Agreement, except (a) as required in connection with the ▇▇▇▇-▇▇▇▇▇-▇▇▇▇▇▇ Antitrust Improvements Act of 1976, as amended (the “HSR Act”), (b) the filing of, and clearance of any SEC comments to, the Proxy Statement (as defined in Section 4.11(a)) with the SEC (as defined in Section 2.6(a)) in accordance with the Exchange Act (as defined in Section 2.6(a)), (c) the approval of Citadel’s stockholders as solicited thereby, (d) the consents listed in Schedule 2.5, and (e) notice filings with Governmental Bodies which are necessary to effect the transfer of the Intellectual Property included within the Assets and which may be made following the Closing Date.

(a) Citadel has made available to Buyer (through reference to documents filed by ▇▇▇▇▇ or otherwise) accurate and complete copies of all reports or registration statements filed by it with the U.S. Securities and Exchange Commission (“SEC”), all in the form so filed (as amended to date, the “Seller SEC Reports”). As of their respective filing dates (or if amended or superseded by a filing prior to the date of this Agreement, then on the filing date of such amending or superseding filing), the Seller SEC Reports (i) were prepared in accordance and complied in all material respects with the requirements of the Securities Act of 1933, as amended (the “Securities Act”), or the Securities Exchange Act of 1934, as amended (the “Exchange Act”), as the case may be, and the rules and regulations of the SEC thereunder applicable to such Seller SEC Reports and, (ii) to the Knowledge of Citadel Parties, did not, at the time they were filed contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, except to the extent corrected by a Seller SEC Report filed prior to the date of this Agreement.

(c) Except as disclosed in the Latest Balance Sheet or in Schedule 2.6(c), no Citadel Entity has any Liabilities (absolute, accrued, contingent or otherwise) which are, individually or in the aggregate, material to the business, results of operations or financial condition of the Citadel Entities taken as a whole, except for (i) liabilities incurred since the Latest Balance Sheet Date in the Ordinary Course of Business that are not, individually or in the aggregate, material to the Citadel Entities and (ii) liabilities incurred pursuant to this Agreement or the Seller Documents.

(d) All accounts receivable reflected in the Latest Balance Sheet or included in the Assets are fully collectible in the Ordinary Course of Business, without resort to

litigation, at the face amount thereof less any reserve reflected in the Latest Balance Sheet, and will not be subject to counterclaim, set-off or other reduction.

(d) Each of the parties agrees to use its commercially reasonable best efforts to take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with the other parties in doing, all things necessary, proper or advisable to consummate and make effective, in the most expeditious manner practicable, the transactions contemplated by this Agreement (subject in each case to Citadel’s right to terminate this Agreement in accordance with Section 4.7(e), subject to compliance with Section 9.2), including using reasonable best efforts to accomplish the following: (i) the taking of all commercially reasonable acts necessary to cause the conditions precedent set forth in Article V to be satisfied, (ii) the obtaining of all necessary actions or nonactions, waivers, consents, approvals, orders and authorizations from Governmental Bodies and the making of all necessary registrations, declarations and filings (including registrations, declarations and filings with Governmental Bodies, if any) and the taking of such reasonable steps as may be necessary to avoid any suit, claim, action, investigation or proceeding by any Governmental Body, (iii) the obtaining of all necessary consents, approvals or waivers from third parties, (iv) the defending of any suits, claims, actions, investigations or proceedings, whether judicial or administrative, challenging this Agreement or the consummation of the transactions contemplated herein, including seeking to have any stay or temporary restraining order entered by any court or other Governmental Body vacated or reversed and (v) the execution or delivery of any additional instruments necessary to consummate the transactions contemplated by, and to fully carry out the purposes of, this Agreement.

(e) Notwithstanding anything in this Agreement to the contrary, nothing contained in this Agreement shall be deemed to require Buyer or Parent or any subsidiary or Affiliate thereof to agree to any divestiture by itself or any of its Affiliates of shares of capital stock or of any business, assets or property, or the imposition of any material limitation on the ability of any of them to conduct their businesses or to own or exercise control of such assets, properties and stock.

4.5 Publicity.

(d) The Transferred Employees will, as of the Closing Date, cease to be active participants in any Employee Benefit Plan that is intended to meet the requirements of Section 401(a) of the Code in accordance with the terms of such plan, and the Citadel Parties will take all action necessary to cause the Transferred Employees to become fully vested in their benefits under each such plan.

(e) Citadel shall take all action necessary to vest in full as of the Closing Date all outstanding stock options, restricted stock or similar awards, if any, granted to Transferred Employees before the Closing Date and to allow Transferred Employees to exercise such options upon a Change of Control (as defined in the applicable plan).

(f) As of or prior to the Closing Date, any and all agreements, or arrangements providing for Change of Control Payments to any Transferred Employee (other than such agreements or arrangements respecting the vesting of restricted stock, options or the termination of options held by such Transferred Employees, payments made with respect to termination of options or payments of the exercise price of any such options pursuant to agreements in effect on the date hereof) will be terminated and no Citadel Party will be obligated to make any such payments to any Transferred Employee in connection with the transactions contemplated herein.

(g) Contemporaneously with the Closing or at the next regular payroll date, Sellers shall: (i) pay to each Transferred Employee all amounts such employee would have received from a Seller under any Seller incentive or performance bonus plan pro-rated for such employee’s term of service during 2006 (including, if the Closing occurs after October 30, 2006, all pro-rated amounts through the Closing Date payable pursuant to the plans described on Schedule 2.13(a)(14-(15)); (ii) pay each Transferred Employee for such employee’s unused vacation time accrued but unpaid as of the Closing Date; and (iii) pay each Transferred Employee all wages accrued but unpaid as of the Closing Date (collectively, the “Transferred Employee Final Payments”).

(i) This Section 4.9 is an agreement solely between the Citadel Parties, Buyer and Parent. Nothing in this Section 4.9, whether express or implied, shall be considered to be a contract between the Citadel Parties, Buyer or Parent and any other Person, or shall confer upon any employee of a Citadel Party, any employee of Buyer, any Transferred Employee or any other Person, any rights or remedies that such Person did not already have, including, (i) any right to employment or recall, (ii) any right to continued employment of any specified Person, or (iii) any right to claim any particular compensation, benefit or aggregation of benefits of any kind or nature whatsoever.

4.10 Tax Information. Each Citadel Party, on the one hand, and Buyer and Parent, on the other hand, will provide the other party with such cooperation and information as each of them reasonably may request of the other in filing any return, amended return or claim for a refund of Taxes, determining a liability for Taxes or a right to refund of Taxes or in conducting any audit or proceeding in respect of Taxes, but only with respect to Taxes imposed upon or related to the Business or the Assets. Such cooperation and information shall include providing copies of relevant returns of Taxes, or portions thereof, imposed upon or related to the Assets, together with associated schedules and related work papers and documents relating to rulings or other determinations by taxing authorities. Each party shall make its employees available on a mutually convenient basis to provide explanation of any documents or information provided hereunder. Each Citadel Party hereby consents to and grants the right to each of Buyer and Parent to speak with, and obtain information from, any third-party provider of tax or accounting services to any Citadel Party following the Closing and hereby waives in favor of each of Buyer and Parent any rights of confidentiality that such providers may owe to any Citadel Party, provided that, before the dissolution of Citadel, this sentence will not require any Citadel Party to cause such third parties with which a Citadel Party has an attorney-client relationship to provide any information that is protected by such attorney-client privilege.

4.11 Proxy Statement.

(a) As promptly as reasonably practicable following the execution and delivery of this Agreement by all parties hereto, Citadel shall prepare and file with the SEC a proxy statement (the “Proxy Statement”) to be sent to Citadel’s stockholders soliciting their adoption and approval of (i) this Agreement and the transactions contemplated hereby, (ii) the Name Changes (as defined in Section 4.14), and (iii) the liquidation, dissolution and winding-down of Citadel’s business after the Closing in a manner providing for full payment to or adequate provision for all creditors of any Citadel Party and otherwise in accordance with all applicable terms of this Agreement and applicable Laws (the “Wind-Down,” and with the matters identified in Section 4.11(a)(i)-(iii), the “Stockholder Approval Matters”). The Proxy Statement shall describe Citadel’s intention to distribute the net proceeds of the transactions contemplated herein to its stockholders within the time period specified therein and shall specify a range of the expected cash amount per share that each stockholder of Citadel is expected to receive upon such distribution based upon Citadel’s good faith estimation of the Remaining

Proceeds (as defined in Section 4.13(b)) as set forth in Schedule 4.13(b). Citadel shall provide draft Proxy Statements to Parent and use commercially reasonable efforts to accept Parent’s comments related thereto.

(b) Citadel shall use its commercially reasonable efforts to respond to any comments of the SEC, and to cause the Proxy Statement to be mailed to Citadel’s stockholders at the earliest practicable time. Citadel will notify the Buyer promptly of the receipt of any comments from the SEC or its staff and of any request by the SEC or its staff for amendments or supplements to the Proxy Statement, or for additional information, and will supply Buyer with copies of all correspondence between Citadel and the SEC or its staff with respect to the Proxy Statement.

(c) Citadel shall use its best efforts to cause all documents that it is responsible for filing with the SEC or other regulatory authorities under this Section 4.11 to comply in all material respects with all applicable requirements of law and the rules and regulations promulgated thereunder. The information included in the Proxy Statement, at the time of mailing, will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they are made, not misleading.

4.12 Meeting of Citadel’s Stockholders.

(a) As promptly as practicable after execution of this Agreement by the parties hereto, Citadel will take all action necessary in accordance with applicable law and Citadel’s certificate of incorporation and bylaws to convene a meeting (the “Citadel Stockholders’ Meeting”) of Citadel’s stockholders to consider adoption and approval of the Stockholder Approval Matters. The Citadel Stockholders’ Meeting shall be held as promptly as practicable. Subject to Section 4.12(e) hereof, Citadel will use its commercially reasonable efforts to solicit from its stockholders proxies in favor of the Stockholder Approval Matters and will take all other action necessary or advisable to secure the vote or consent of its stockholders required by its certificate of incorporation, its bylaws or applicable Law to obtain such approvals.

(b) Notwithstanding anything to the contrary contained in this Agreement, Citadel may adjourn or postpone the Citadel Stockholders’ Meeting to the extent necessary to ensure that any necessary supplement or amendment to the Proxy Statement is provided to Citadel’s stockholders in advance of a vote, or if as of the time for which Citadel’s Stockholders’ Meeting is originally scheduled (as set forth in the Proxy Statement) there are insufficient shares of Citadel’s common stock represented (either in person or by proxy) to constitute a quorum necessary to conduct the business of the Citadel Stockholders’ Meeting.

(c) Citadel shall ensure that the Citadel Stockholders’ Meeting is called, noticed, convened, held and conducted, and that all proxies solicited by Citadel in connection with the Citadel Stockholders’ Meeting are solicited, in compliance with applicable law and the certificate of incorporation and bylaws of Citadel.

(iii) in addition to the Indemnification Reserve contemplated by Section 4.13(b)(i) and the COBRA Reserve contemplated by Section 4.13(b)(ii), during the Indemnification Period and thereafter until the Citadel Parties’ indemnification obligations under Section 6.1(e) expire pursuant to Section 6.3(d), Citadel will set aside and not distribute to its stockholders $540,000 exclusively for purposes of fulfilling its obligations under Section 6.1(e) (the “Additional Reserve”); provided, however, this obligation will expire when the related indemnification obligation expires in accordance with Section 6.3(d);

(iv) if any Buyer Party (as described in Section 6.1) has given Citadel notice of any Claim (as defined in Section 6.4) during the Indemnification Period for Losses (as defined in Section 6.1), Citadel will not distribute any amount to its stockholders unless it retains a sufficient amount of cash, not to exceed the Indemnification Reserve, exclusively to pay the dollar amount of such Claim as well as all other Wind-Down Obligations; and

(v) prior to each distribution to its stockholders, Citadel must deliver a certificate, signed by a senior officer of Citadel on behalf of Citadel, specifically indicating that, following such distribution, the Citadel Parties will have enough cash or cash equivalents to satisfy their Wind-Down Obligations, pay any Liabilities in connection with the California Tax Audit as defined in Schedule 2.8, maintain the COBRA Reserve (if applicable), maintain the Additional Reserve (if applicable) and, during the Indemnification Period, maintain the Indemnification Reserve; such certificate shall also: (i) identify the number of Persons who have elected COBRA Continuation Coverage, (ii) the number of Persons who are eligible for COBRA Continuation Coverage but has not yet elected, and (iii) provide an actuarial analysis of Citadel’s estimated remaining liability, which may be zero, for COBRA Continuation Coverage (the “COBRA Amount”).

(c) The Citadel CEO shall be permitted to remain as an officer of Citadel to oversee the winding-down of the business of the Citadel Parties and the Citadel distributions contemplated by this Agreement.

4.16 Voluntary Self-Disclosure Proceedings. From and after the Closing Date, the Citadel Parties shall continue to take all necessary actions to complete, in accordance with the EAR, the voluntary self-disclosure proceedings initiated pursuant to Section 5.1(p), including cooperating with Parent as reasonably requested by Parent and responding to any follow-up requests by any Governmental Body.

(e) Notwithstanding anything to the contrary herein, any representation or warranty the violation of which is made the basis of a claim for indemnification pursuant to Section 6.1 or Section 6.2 will survive until such claim is finally resolved if Parent or Buyer notifies the Sellers, or if the Sellers notify the Buyer, as applicable, of such claim in reasonable detail prior to the Expiration Date.

(f) The covenants and agreements of the Sellers, the Buyer and Parent made in or pursuant to this Agreement will survive the execution and delivery of this Agreement and the consummation of the transactions contemplated hereby indefinitely, but, subject to Sections 6.3(c), (d) and (e), and except in cases of fraud or intentional breach, the indemnification obligations with respect to such agreements and covenants shall expire on the Expiration Date.

6.4 Notice. Any party entitled to receive indemnification under this Article VI (the “Indemnified Party”) agrees to give prompt written notice to the party required to provide such indemnification (the “Indemnifying Party”) promptly after becoming aware of the occurrence of any indemnifiable Loss or the assertion of any claim or the commencement of any action or proceeding in respect of which such a Loss may reasonably be expected to occur (a “Claim”), but the Indemnified Party’s failure to give such notice will not affect the obligations of the Indemnifying Party under this Article VI except to the extent that the Indemnifying Party is materially prejudiced thereby. Such written notice will include a reference to the event or events forming the basis of such Loss or Claim and the amount involved, unless such amount is uncertain or contingent, in which event the Indemnified Party will give a later written notice when the amount becomes fixed.

6.5 Defense of Claims.

(a) The Indemnifying Party may elect to assume and control the defense of any Claim, including the employment of counsel reasonably satisfactory to the Indemnified

Party and the payment of expenses related thereto, if: (i) the Indemnifying Party acknowledges its obligation to indemnify the Indemnified Party for any Losses resulting from such Claim; (ii) the Claim does not seek to impose any Liability on the Indemnified Party other than money damages; (iii) the Claim does not relate to the Indemnified Party’s relationship with any customer, supplier or employee; (iv) the Claim or Loss is not part of a larger claim or series of claims that do not relate to Losses hereunder; or (v) the Indemnified Party does not otherwise believe, for confidentiality reasons or because of the importance of the Claim to the Indemnified Party’s business, that allowing the Indemnifying Part to prosecute the defense of such claim would be adverse to the Indemnified Party’s interests.

(b) If the conditions of Section 6.5(a) are satisfied and the Indemnifying Party elects to assume and control the defense of a Claim, then: (i) the Indemnifying Party will not be liable for any settlement of such Claim effected without its consent, which consent will not be unreasonably withheld; (ii) the Indemnifying Party may settle such Claim without the consent of the Indemnified Party only if (A) all monetary damages payable in respect of the Claim are paid by the Indemnifying Party, (B) the Indemnified Party receives a full, complete and unconditional release in respect of the Claim without any admission or finding of obligation, liability, fault or guilt (criminal or otherwise) with respect to the Claim, and (C) no injunctive, extraordinary, equitable or other relief of any kind is imposed on the Indemnified Party or any of its Affiliates; (iii) the Indemnifying Party may otherwise settle such Claim only with the consent of the Indemnified Party, which consent will not unreasonably be withheld or delayed; and (iv) the Indemnified Party may employ separate counsel and participate in the defense thereof, but the Indemnified Party will be responsible for the fees and expenses of such counsel unless: (1) the Indemnifying Party has failed to adequately assume and actively conduct the defense of such Claim or to employ counsel with respect thereto; or (2) in the reasonable opinion of the Indemnified Party, an actual or potential conflict of interest exists between the interests of the Indemnified Party and the Indemnifying Party that requires representation by separate counsel, in which case the fees and expenses of such separate counsel will be paid by the Indemnifying Party.

(c) If the conditions of Section 6.5(a) are not satisfied, the Indemnified Party may assume the exclusive right to defend, compromise or settle such Claim, but the Indemnifying Party will not be bound by any determination of a Claim so defended or any compromise or settlement effected without its consent (which may not be unreasonably withheld); provided, that the Indemnified Party will not be required to obtain any consent of the Indemnifying Party to the determination of such Claim (and will not prejudice its right to be indemnified with respect to such Claim by settling such Claim) if the Indemnifying Party is asserting that it has no obligation to indemnify the Indemnified Party in respect of such claim.

6.6 Amount Limitation of Indemnification.

(a) The Citadel Parties shall have no liability (for indemnification or otherwise) for Losses of any Buyer Party arising from any breach of any representation or warranty set forth in Article II hereof or covenants or agreements of Citadel Parties set

forth in this Agreement until the aggregate amount of all such Losses with respect to such matters exceeds $250,000 (the “Threshold”); provided, however, if such Losses, in the aggregate, exceed the Threshold, then the Buyer Parties shall be entitled to recover the full amount of all such Losses (from dollar one) up the Maximum Amount (as defined in Section 6.6(b)); provided, further, the limitation set forth in this Section 6.6(a) shall not apply to any Losses arising from a breach of any representation or warranty set forth in Article II hereof of which the Citadel Parties had Knowledge at or prior to the date hereof or that would constitute fraud.

(b) The Citadel Parties’ aggregate liability under this Article VI for Losses of any Buyer Party arising from any breach of any representation or warranty set forth in Article II hereof or covenants or agreements of Citadel Parties set forth in this Agreement shall not exceed $3,000,000 (the “Maximum Amount”); provided, however, the limitation set forth in this Section 6.6(b) shall not apply to any Losses arising from a breach of any representation or warranty set forth in Article II hereof of which the Citadel Parties had Knowledge at or prior to the date hereof or that would constitute fraud.

(c) If the Closing occurs, except with respect to (i) claims of fraud, intentional misrepresentation or intentional breach of a representation or warranty and (ii) claims for injunctive or other equitable non-monetary relief, after the Closing Date the amounts set forth in this Section 6.6 are the Buyer Parties’ sole and exclusive remedy for indemnification under this Article VI and for breaches by the Citadel Parties of this Agreement and the certificates delivered pursuant to Section 5.1(s).

ARTICLE VII
Covenant Not to Compete or Solicit

7.1 Covenant Not to Compete. Subject to the Closing, and beginning on the Closing Date and ending on the date that is two years from the Closing Date (the “Non-Competition Period”), without the prior written consent of Parent, no Citadel Party shall directly or indirectly engage in a Competitive Business Activity (as defined below) anywhere in the Restricted Territory (as defined below). For all purposes hereof, the term “Competitive Business Activity” shall mean: (i) engaging in, or managing or directing Persons engaged in, any business that in any way competes with the Business; (ii) acquiring or having an ownership interest in any entity which derives revenues from any business that in any way competes with the Business; or (iii) participating in the financing, operation, management or control of any firm, partnership, corporation, entity or business that derives revenues from any business that in any way competes with the Business. For all purposes hereof, the term “Restricted Territory” shall mean each and every country, province, state, city or other political subdivision of the world including those in which any Citadel Party is currently engaged in business or otherwise distributes, licenses or sells products.

7.2 Covenant Not to Solicit. Subject to the Closing, and during the Non-Competition Period, no Citadel Party shall, directly or indirectly, hire or solicit, encourage or take any other action which is intended to induce or encourage any employee of Parent or any subsidiary of

Parent or any Key Employee or Transferred Employee to terminate his or her employment with Parent or any subsidiary of Parent.

7.3 Enforcement. The covenants contained in this Article VII shall be construed as a series of separate covenants, one for each country, province, state, city or other political subdivision of the Restricted Territory. Except for geographic coverage, each such separate covenant shall be deemed identical in terms to the covenant contained in this Article VII. If, in any judicial proceeding, a court refuses to enforce any of such separate covenants (or any part thereof), then such unenforceable covenant (or such part) shall be eliminated from this Agreement to the extent necessary to permit the remaining separate covenants (or portions thereof) to be enforced. In the event that the provisions of this Article VII are deemed to exceed the time, geographic or scope limitations permitted by applicable law, then such provisions shall be reformed to the maximum time, geographic or scope limitations, as the case may be, permitted by applicable laws.

7.4 Acknowledgement of Consideration. Each Citadel Party acknowledges that (i) the value of the Assets is an integral component of the value of the Business to Buyer and Parent and is reflected in the value of the consideration to be received by the Citadel Parties pursuant to this Agreement, and (ii) the agreement of each of the Citadel Parties as set forth in this Article VII is necessary to preserve the value of the Assets for Buyer following the Closing. Each Citadel Party also acknowledges that the limitations of time, geography and scope of activity agreed to in this Article VII are reasonable because, among other things, (A) Parent is engaged in a highly competitive industry, (B) such Citadel Party has had unique access to trade secrets and know-how of the Assets including, the plans and strategy (and, in particular, the competitive strategy) relating to the Assets, and (C) such Citadel Party is receiving significant consideration in connection with the consummation of the transactions contemplated by this Agreement.

7.5 Remedies. The parties agree that in the event of a breach by any Citadel Party of any of the covenants set forth in this Article VII, monetary damages alone would be inadequate to fully protect Buyer and Parent from, and compensate Buyer and Parent for, the harm caused by such breach or threatened breach. Accordingly, each Citadel Party agrees that if it breaches or threatens breach of any provision of this Article VII, each of Buyer and Parent shall be entitled to, in addition to any other right or remedy otherwise available, the right to injunctive relief restraining such breach or threatened breach and to specific performance of any such provision of this Article VII, and Buyer or Parent, as applicable, shall not be required to post a bond in connection with, or as a condition to, obtaining such relief before a court of competent jurisdiction.

ARTICLE VIII
Termination, Amendment And Waiver

8.1 Termination. Without limiting the provisions of Section 8.2, this Agreement may be terminated and the transactions contemplated hereby abandoned at any time prior to the Closing whether before or after the requisite approval of the stockholders of Citadel:

(a) by mutual written consent of Parent and Citadel;

(b) by any party if the Closing Date shall not have occurred by December 29, 2006 (the “End Date”) for any reason; provided, however, that the right to terminate this Agreement under this Section 8.1(b) shall not be available to any party whose (or whose Affiliate’s) action or failure to act has been a principal cause of or resulted in the failure of the Closing Date to occur on or before such date and such action or failure to act constituted a breach of this Agreement;

(c) by any party if a Governmental Entity shall have issued an order, decree or ruling or taken any other action, in any case having the effect of permanently restraining, enjoining or otherwise prohibiting the transactions contemplated hereby, which order, decree, ruling or other action is final and nonappealable;

(e) by Parent (at any time prior to Stockholder Approval) if a Seller Triggering Event (as defined below) shall have occurred;

(f) by Parent, upon a breach of any representation, warranty, covenant or agreement on the part of any Seller set forth in this Agreement, or if any representation or warranty of any Citadel Party shall have become untrue, in either case such that the conditions set forth in Section 5.1 would not be satisfied as of the time of such breach or as of the time such representation or warranty shall have become untrue; provided, that if such inaccuracy in a Citadel Party’s representations and warranties or breach by a Seller is curable by such Citadel Party through the exercise of its commercially reasonable efforts, then Parent may not terminate this Agreement under this Section 8.1(f) prior to the date that is twenty (20) business days following the date of such breach, provided the applicable Citadel Party continues to exercise commercially reasonable efforts to cure such breach (it being understood that Parent may not terminate this Agreement pursuant to this paragraph (f) if such breach by a Citadel Party is cured prior to the date that is twenty (20) business days following the date of such breach);

(g) by Citadel, upon a breach of any representation, warranty, covenant or agreement on the part of Buyer or Parent set forth in this Agreement, or if any representation or warranty of Buyer or Parent shall have become untrue, in either case such that the conditions set forth in Section 5.2 would not be satisfied as of the time of such breach or as of the time such representation or warranty shall have become untrue, provided, that if such inaccuracy in Buyer’s or Parent’s representations and warranties or breach by Buyer or Parent is curable by such party through the exercise of its commercially reasonable efforts, then Citadel may not terminate this Agreement under this Section 8.1(g) prior to the date that is twenty (20) business days following the date of

(h) by Citadel pursuant to Section 4.7(e).

For the purposes of this Agreement, a “Seller Triggering Event” shall be deemed to have occurred if: (i) the Board of Directors of Citadel or any committee thereof shall for any reason have withdrawn or shall have amended or modified in a manner adverse to Buyer or Parent its recommendation in favor of the adoption and approval of the Stockholder Approval Matters; (ii) Citadel shall have failed to include in the Proxy Statement the recommendation of the Board of Directors of Citadel in favor of the adoption and approval of the Stockholder Approval Matters; (iii) the Board of Directors of Citadel fails to reaffirm its recommendation in favor of the adoption and approval of the Stockholder Approval Matters within ten (10) days after Parent requests in writing that such recommendation be reaffirmed (unless Citadel (w) indicates in writing during such 10-day period to Parent that the failure to reaffirm such recommendation is because of Citadel’s Knowledge of a Claim for Losses (or the basis therefor), (x) describes such Claim and Losses in reasonable detail in writing to Parent within such 10-day period, (y) indicates in writing to Parent that, in the opinion of the Board of Directors, such Claim and Losses will result in indemnification payments to Parent that will significantly impact the value of the transactions contemplated hereby for Citadel’s stockholders, and (z) indicates in writing to Parent that the Board of Directors and Citadel are not considering any Takeover Proposals (other than the transactions contemplated hereby); (iv) the Board of Directors of Citadel or any committee thereof shall have approved or recommended any Takeover Proposal other than by Buyer or Parent; or (v) a tender or exchange offer relating to securities of a Citadel Party shall have been commenced by a Person unaffiliated with Buyer or Parent, and Citadel shall not have sent to its securityholders pursuant to Rule 14e-2 promulgated under the Securities Act, within ten (10) business days after such tender or exchange offer is first published sent or given, a statement disclosing that Citadel’s Board of Directors recommends rejection of such tender or exchange offer; or (vi) Citadel terminates this Agreement pursuant to Section 4.7(e).

9.2 Fees and Expenses.

(a) General. Except as set forth in this Section 9.2 and as set forth in Section 4.6, all fees and expenses incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the party incurring such expenses whether or not the transactions contemplated hereby are consummated. If attorneys’ fees or other costs are incurred to secure performance of any obligations hereunder, or to establish damages for the breach thereof or to obtain any other appropriate relief, whether by way of prosecution or defense, the Prevailing Party (as defined below) will be entitled to recover reasonable attorneys’ fees and costs incurred in connection therewith. A party will be considered the “Prevailing Party” if: (a) it initiated the litigation and substantially obtained the relief it sought, either through a judgment or the losing party’s voluntary action before trial or judgment; (b) the other party withdraws its action without substantially obtaining the relief it sought; or (c) it did not initiate the litigation and judgment is entered into for any party, but without substantially granting the relief sought by the initiating party or granting more substantial relief to the non-initiating party with respect to any counterclaim asserted by the non-initiating party in connection with such litigation.

(b) Termination Fee.

(i) In the event that: (A) Parent shall terminate this Agreement pursuant to Section 8.1(e), (B) Parent shall terminate this Agreement pursuant to Section 8.1(f) and within twelve months after such termination, a Citadel Party shall enter into a definitive agreement with respect to any Takeover Proposal or any Takeover Transaction shall be consummated, (C) this Agreement shall be terminated pursuant to Section 8.1(b) or Section 8.1(d) and (1) at or prior to such termination, there shall exist or have been proposed a Takeover Transaction (other than one proposed by Buyer or Parent or an Affiliate thereof), and (2) within twelve months after such termination, a Citadel Party shall enter into a definitive agreement with respect to such Takeover Proposal or a Takeover Transaction shall be consummated with respect to such Takeover Proposal, or (D) Citadel shall terminate this Agreement pursuant to Section 8.1(h) or Section 4.7(e); then, in the case of (A) and (D), within one business day after the date of such termination, and in the case of (B) or (C), upon the earlier to occur of (x) one business day after the entering into of a definitive agreement with respect to any Takeover Proposal and (y) immediately prior to the consummation of a Takeover Transaction, Citadel shall pay Parent an amount in cash equal to $2,320,000 (the “Termination Fee”). Notwithstanding the foregoing, the parties acknowledge that the Termination Fee does not represent a liquidated damage amount for any breach by any Citadel Party of any provision of this Agreement, and shall be payable in addition to and irrespective of any amount otherwise recoverable by Buyer or Parent under this Agreement or otherwise by reason of such breach; provided, however, if the Closing does not occur and Citadel pays the Termination Fee in accordance with the terms hereof, Buyer and Parent may not bring any claim under this Agreement related to a breach of the representations or warranties of a Citadel Party unless such breach was fraudulent, intentional or willful.

(ii) Each Citadel Party acknowledges that the agreements contained in this Section 9.2(b) are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, Parent and Buyer would not enter into this Agreement. Accordingly, if Citadel fails to pay in a timely manner the amounts due pursuant to this Section 9.2(b) and, in order to obtain such payment, Buyer or Parent makes a claim that results in a judgment against Citadel for the amounts set forth in this Section 9.2(b), Citadel shall pay to Buyer or Parent, as applicable, its costs and expenses (including reasonable attorneys’ fees and expenses) in connection with such suit, together with interest on the amounts set forth in this Section 9.2(b) at the prime rate of Bank of America N.A. in effect on the date such payment was required to be made.

9.3 Counterparts. This Agreement may be executed in one or more counterparts (including by facsimile or portable document format (pdf)) for the convenience of the parties hereto, each of which will be deemed an original, but all of which together will constitute one and the same instrument. No signature page to this Agreement evidencing a party’s execution

hereof will be deemed to be delivered by such party to any other party hereto until such delivering party has received signature pages from all parties signatory to this Agreement.

9.4 Interpretation. The article and section headings contained in this Agreement are solely for the purpose of reference, are not part of the agreement of the parties and will not in any way affect the meaning or interpretation of this Agreement.

9.5 Severability. The invalidity or unenforceability of any provision of this Agreement will not affect the validity or enforceability of any other provision of this Agreement, each of which will remain in full force and effect, so long as the economic or legal substance of the transactions contemplated by this Agreement is not affected in a manner materially adverse to any party.

9.6 Binding Effect; Assignment. This Agreement will be binding upon and inure to the benefit of the parties and their respective successors and permitted assigns. Neither this Agreement nor any of the rights, interests or obligations hereunder may be assigned or delegated by any party without the prior written consent of the other parties hereto; provided, however, Buyer may assign its rights and obligations hereunder to any direct or indirect wholly owned subsidiary of Parent. This Agreement is not intended to confer any rights or benefits on any Person other than the parties hereto, and to the extent provided in Article VI, the Buyer Parties and the Seller Parties.

9.7 Entire Agreement, Amendment. This Agreement and the related documents contained as Exhibits and Schedules (as the same may be supplemented as provided herein) hereto or expressly contemplated hereby contain the entire understanding of the parties relating to the subject matter hereof and supersede all prior written or oral and all contemporaneous oral agreements and understandings relating to the subject matter hereof (including the letter entitled “Proposal to Purchase Assets” from Parent to the Board of Directors of Citadel dated July 31, 2006), but specifically excluding the Existing NDA, which shall remain in full force and effect. All statements of each Citadel Party contained in any schedule (as the same may be supplemented as provided herein), certificate or other writing required under this Agreement to be delivered in connection with the transactions contemplated hereby will constitute representations and warranties of such Citadel Party under this Agreement. The Exhibits, Schedules (as the same may be supplemented as provided herein) and recitals to this Agreement are hereby incorporated by reference into and made a part of this Agreement for all purposes. This Agreement may be amended, supplemented or modified, and any provision hereof may be waived, only by written instrument making specific reference to this Agreement signed by the party against whom enforcement is sought.

9.8 Specific Performance, Remedies Not Exclusive. The parties hereby acknowledge and agree that the failure of any party to perform its agreements and covenants hereunder, including its failure to take all required actions on its part necessary to consummate the transactions contemplated hereby, will cause irreparable injury to the other parties for which damages, even if available, will not be an adequate remedy. Accordingly, each party hereby consents to the issuance of injunctive relief by any court of competent jurisdiction to compel performance of such party’s obligations and to the granting by any court of the remedy of specific performance of its obligations hereunder. Unless otherwise expressly stated in this

Agreement, no right or remedy described or provided in this Agreement is intended to be exclusive or to preclude a party from pursuing other rights and remedies to the extent available under this Agreement, at law or in equity.

9.9 GOVERNING LAW. THIS AGREEMENT WILL BE GOVERNED BY AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH THE SUBSTANTIVE LAWS OF THE STATE OF DELAWARE, WITHOUT GIVING EFFECT TO ANY CONFLICTS OF LAW RULE OR PRINCIPLE THAT MIGHT RESULT IN THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION.

9.10 JURISDICTION AND VENUE. EACH OF THE PARTIES HERETO CONSENTS TO THE EXCLUSIVE JURISDICTION AND VENUE OF ANY COURT WITHIN DALLAS, COUNTY, STATE OF TEXAS, IN CONNECTION WITH ANY MATER BASED UPON OR ARISING OUT OF THIS AGREEMENT OR THE MATTERS CONTEMPLATED HEREIN, AGREES THAT PROCESS MAY BE SERVED UPON THEM IN ANY MANNER AUTHORIZED BY THE LAWS OF THE STATE OF TEXAS FOR SUCH PERSONS AND WAIVES AND COVENANTS NOT TO ASSERT OR PLEAD ANY OBJECTION WHICH THEY MIGHT OTHERWISE HAVE TO SUCH JURISDICTION, VENUE AND SUCH PROCESS.
