2.1 Sale and Purchase of Securities. Upon the terms and subject to the conditions contained herein, on the Closing Date, each Seller agrees to sell to Purchaser, free and clear of any and all Liens, and Purchaser agrees to purchase from each Seller, the Securities owned by such Seller and listed on Exhibit A hereto.

2.2 Purchase Price. The aggregate purchase price to be paid by Purchaser for the Securities shall be an amount in cash equal to $251,000,000 (a) less (i) the Aggregate Retention Amount and (ii) any Company Transaction Expenses unpaid as of the Closing Date and (b) subject to adjustment as provided in Section 2.3 (the “Purchase Price”), subject to further adjustment as provided in Section 2.5.

2.3 Severance Adjustment Amount. If the aggregate of the severance for the Non-Transferred Employees is less than $3,000,000, the Purchase Price shall be reduced by the amount of such difference (the “Severance Amount Shortfall”). For purposes hereof, the amount of severance for each Non-Transferred Employee shall be equal to the lesser of (a) the amount of severance for such Non-Transferred Employee reflected in Exhibit E of the Side Letter and (b) the amount of severance for such Non-Transferred Employee determined under the applicable severance policy of the Sellers in effect as of the date hereof (other than the individuals set forth on Schedule 2.3, which

individuals shall not be considered for purposes of aggregation) and set forth in the Severance Notice.

2.4 Payment of Purchase Price. The Side Letter sets forth the Retention Amount for each Continuing Employee determined (a) as if the Closing Date were November 30, 2005, (b) assuming that all Business Employees are Transferred Business Employees and (c) assuming that the CSG Common Stock Closing Price is $21.70. The Aggregate Retention Amount shall be determined utilizing the information set forth in the Side Letter and making only necessary adjustments to contemplate the actual Closing Date, the actual CSG Common Stock Closing Price, the actual Non-Transferred Employees, any termination of such rights triggered as a result of the termination of employment of the holder thereof, any further acceleration of vesting of such options to acquire CSG Common Stock or shares of CSG Common Stock subject to restrictions, in each case, in accordance with the Side Letter and the inclusion of additional Business Employees engaged by the Sellers and their Affiliates (other than the Companies and Subsidiaries) in the Integrated Customer Management System business; provided that the aggregate value of the unvested options to acquire CSG Common Stock (based upon the spread between an assumed stock market price of $21.70 per share and the exercise price per share) and CSG Common Stock subject to restrictions (based on a stock market price of $21.70 per share) held by such additional Business Employees shall not exceed $250,000. The Sellers shall, within 10 Business Days after the date hereof, provide Purchaser an updated Exhibit A to the Side Letter solely to reflect the inclusion of additional Business Employees engaged by the Sellers and their Affiliates (other than the Companies and Subsidiaries) in the Integrated Customer Management System business. Two (2) Business Days prior to the Closing Date, the Sellers and Purchaser shall agree, in good faith, upon the Escrow Amount and the amount of adjustments to the Purchase Price contemplated by clause (a) of Section 2.2. On the Closing Date, Purchaser shall pay the Purchase Price, as so calculated, to the Sellers in the percentages set forth in a letter to be delivered by the Sellers to Purchaser at least three (3) days prior to Closing by wire transfer of immediately available funds into accounts designated in such letter. On the Closing Date, Purchaser shall pay the Escrow Amount to the Escrow Agent in cash payable by wire transfer of immediately available funds for deposit into the Escrow Account.

2.5 Purchase Price Adjustment.

(a) Closing Working Capital. Following the Closing, the Purchase Price shall be adjusted as provided herein in the event that (i) Closing Working Capital is less than the Target Working Capital, (ii) Purchaser elects to acquire the Excess Cash Amount by paying the amount calculated in accordance with Section 7.3(e) or (iii) the Cash of the Companies and Subsidiaries as of the Closing Date (the “Closing Cash”) exceeds $1,100,000. “Target Working Capital” shall be negative $21,000,000. “Closing Working Capital” means (A) the combined Included Current Assets of the Companies and Subsidiaries, less (B) the combined Included Current Liabilities of the Companies and Subsidiaries, plus (C) the sum of Working Capital Adjustments, all determined as of the opening of business on the Closing Date. “Included Current

Assets” means current assets of the Companies and Subsidiaries, as defined under, and determined in accordance with, GAAP applied using the same accounting methods, practices, principles, policies and procedures, with consistent classifications, judgments and valuation and estimation methodologies that were used in the preparation of the audited consolidated financial statements of CSG and its subsidiaries for the most recent fiscal year end as if such accounts were being prepared and audited as of a fiscal year end. “Included Current Liabilities” means current liabilities of the Companies and Subsidiaries as defined under, and determined in accordance with, GAAP applied using the same accounting methods, practices, principles, policies and procedures, with consistent classifications, judgments and valuation and estimation methodologies that were used in the preparation of the audited consolidated financial statements of CSG and its subsidiaries for the most recent fiscal year end as if such accounts were being prepared and audited as of a fiscal year end. “Working Capital Adjustments” means the sum of the following adjustments: (A) a negative adjustment equal to the amount of Cash of the Companies and Subsidiaries, (B) a negative adjustment equal to $2,500,000, which is related to a predetermined adjustment for the allowance for doubtful accounts, (C) a negative adjustment equal to the excess of (1) the full amount of unpaid 2005 incentive bonus compensation for Continuing Employees expected to be accrued as of December 31, 2005 over (2) the amount of accrued but unpaid 2005 incentive bonus compensation for Continuing Employees reflected in the Included Liabilities, (D) a negative adjustment equal to the non-current deferred revenue of the Companies and Subsidiaries, (E) a negative adjustment of $5,000,000 in respect of a reserve for Taxes (it being understood and agreed that Included Current Liabilities will not otherwise include any reserve for income Tax contingencies determined in accordance with Statement of Financial Accounting Standards No. 5), and (F) the Closing Working Capital Statement shall not reflect (whether or not it would otherwise reflect) any asset or Liability in respect of any Tax resulting from, arising out of or based on the sale of the Securities hereunder, including any Tax arising as a result of the Section 338(h)(10) Election (as defined in Section 9.8) and any income or franchise Tax payable to any Tax Authority with respect to which the Company or Subsidiary has filed or will file an affiliated, consolidated, combined or unitary Tax Return with a Seller or any of their Affiliates to the extent that such Tax is required to be paid by the Sellers or any of their Affiliates (other than the Companies or Subsidiaries) under applicable Law. All components of Closing Working Capital shall be calculated after taking into account the actions taken pursuant to Section 6.10, excluding the FairPoint Business and excluding any intercompany accounts receivable or accounts payable between the Companies and Subsidiaries, on the one hand, and CSG and its subsidiaries (other than the Companies and Subsidiaries), on the other. Schedule 2.5(a) provides an illustrative example of the calculations of Closing Working Capital derived from the unaudited consolidated financial statements of CSG and its subsidiaries as of June 30, 2005.

(b) Closing Net Assets Statement. Within 60 days following the Closing Date, Purchaser shall deliver to the Sellers an unaudited combined statement of net assets of the Companies and Subsidiaries (exclusive of the assets and Liabilities of the FairPoint Business) as of the opening of business on the Closing Date (the “Closing Net

Assets Statement”), a statement of Closing Working Capital derived from the Closing Net Assets Statement (the “Closing Working Capital Statement”) and a statement of the Closing Cash, the Excess Cash Amount and the resulting Cash Adjustment Amount, if any, derived from the Closing Net Assets Statement (the “Closing Cash Statement”). Schedule 2.5(b) provides an illustrative example of the calculations of the Cash Adjustment Amount derived from the unaudited consolidated financial statements of CSG and its subsidiaries as of June 30, 2005. The Closing Net Assets Statement shall be derived from the unaudited financial statements of CSG and its subsidiaries prepared in accordance with GAAP applied using the same accounting methods, practices, principles, policies and procedures, with consistent classifications, judgments and valuation and estimation methodologies that were used in the preparation of the audited consolidated financial statements for CSG and its subsidiaries for the most recent fiscal year end as if such Closing Net Assets Statement was as of a fiscal year end.

(c) Acceptance of Statements; Dispute Procedures. The Closing Net Assets Statement, the Closing Working Capital Statement and the Closing Cash Statement delivered by Purchaser to the Sellers shall be conclusive and binding upon the parties unless the Sellers, within 30 days after delivery to the Sellers of the Closing Net Assets Statement, the Closing Working Capital Statement and the Closing Cash Statement, notify Purchaser in writing that the Sellers dispute any of the amounts set forth therein, specifying the nature of the dispute and the basis therefor. The parties shall in good faith attempt to resolve any dispute and, if the parties so resolve all disputes, the Closing Net Assets Statement, the Closing Working Capital Statement and the Closing Cash Statement, as amended to the extent necessary to reflect the resolution of the dispute, shall be conclusive and binding on the parties. If the parties do not reach agreement in resolving the dispute within 20 days after notice is given by the Sellers to Purchaser pursuant to the second preceding sentence, the parties shall submit the dispute to a mutually satisfactory partner in the New York City office of the accounting firm of PricewaterhouseCoopers or, if no partner at such firm will act, to a partner at such other nationally recognized independent accounting firm which is mutually agreeable to the parties (who shall not have any material relationship with Purchaser or Seller) (the “Arbiter”) for resolution. If the parties cannot agree on the selection of a partner at an independent accounting firm to act as Arbiter, the parties shall request the American Arbitration Association to appoint such a partner, and such appointment shall be conclusive and binding on the parties. Promptly, but no later than 20 days after acceptance of his or her appointment as Arbiter, the Arbiter shall determine (it being understood that in making such determination, the Arbiter shall be functioning as an expert and not as an arbitrator), based solely on written submissions by Purchaser and the Seller, and not by independent review, only those issues in dispute and shall render a written report as to the resolution of the dispute and the resulting computation of the Closing Working Capital and the Cash Adjustment Amount which shall be conclusive and binding on the parties. All proceedings conducted by the Arbiter shall take place in The City of New York. In resolving any disputed item, the Arbiter (x) shall be bound by the provisions of this Section 2.5 and (y) may not assign a value to any item greater than the greatest value for such item claimed by either party or less than the smallest value for

such item claimed by either party. The fees, costs and expenses of the Arbiter shall be allocated to and borne by Purchaser and the Sellers based on the inverse of the percentage that the Arbiter’s determination (before such allocation) bears to the total amount of the items in dispute as originally submitted to the Arbiter. For example, should the items in dispute total in amount to $1,000 and the Arbiter awards $600 in favor of the Seller’s position, 60% of the costs of its review would be borne by Purchaser and 40% of the costs would be borne by the Seller.

(d) Payment. Upon final determination of Closing Working Capital as provided in Section 2.5(c) above, if Closing Working Capital is less than Target Working Capital, the Purchase Price shall be decreased by the excess (the “Purchase Price Decrease”) of Target Working Capital over the Closing Working Capital. Upon final determination of the Cash Adjustment Amount, if any, as provided in Section 2.5(c) above, the Purchase Price shall be increased by the Cash Adjustment Amount, if any, (the “Purchase Price Increase”). If the Purchase Price Decrease exceeds the Purchase Price Increase, the Sellers shall promptly pay to Purchaser the amount of such excess no later than five (5) Business Days after such final determination, together with interest thereon from the Closing Date to the date of payment thereof at the “prime” rate, as announced by The Wall Street Journal, Eastern Edition, from time to time to be in effect, calculated based on a 365 day year and the actual number of days elapsed, and all amounts in the Escrow Account shall be released to Purchaser. If the Purchase Price Increase exceeds the Purchase Price Decrease, Purchaser shall promptly pay to the Sellers in the percentages set forth in the letter referenced in Section 2.4 the amount of such excess no later than five (5) Business Days after such final determination, together with interest thereon from the Closing Date to the date of payment thereof at the “prime” rate, calculated as set forth in the immediately preceding sentence. Any payment to be made by Purchaser to the Sellers pursuant to this Section 2.5(d) will first be made as a payment from the Escrow Account and any amounts remaining in the Escrow Account thereafter shall be released to Purchaser.

2.6 Closing Date. The consummation of the sale and purchase of the Securities provided for in Section 2.1 hereof (the “Closing”) shall take place at the offices of Weil, Gotshal & Manges LLP located at 767 Fifth Avenue, New York, New York 10153 (or at such other place as the parties may designate in writing) at 10:00 a.m. (New York City time) on a date to be specified by the parties (the “Closing Date”), which date shall be no later than the second Business Day after the satisfaction or waiver of the conditions set forth in Article VIII (other than conditions that by their nature are to be satisfied at Closing, but subject to the satisfaction or waiver of those conditions at such time), unless another time, date or place is agreed to in writing by the parties hereto.

2.7 Seller Deliveries on the Closing Date. At the Closing, the Sellers shall deliver or cause each Company to deliver, as applicable, to Purchaser:

(a) Copies of resolutions, certified by the Secretary of each Company and an authorized person of the Seller, respectively, as to the authorization of this Agreement and all of the transactions contemplated hereby.

Without limiting the foregoing, Purchaser, the Sellers and the Companies shall (i) make all filings required of each of them or any of their respective Subsidiaries or Affiliates under the HSR Act or other Antitrust Laws with respect to the transactions contemplated hereby as promptly as practicable and, in any event, within ten (10) Business Days after the date of this Agreement in the case of all filings required under the HSR Act and within four (4) weeks in the case of all other filings required by other Antitrust Laws, (ii) promptly comply with any request under the HSR Act or other Antitrust Laws for additional information, documents, or other materials received by each of them or any of their respective Subsidiaries or Affiliates from the U.S. Federal Trade Commission (the “FTC”), the Antitrust Division of the U.S. Department of Justice (the “Antitrust Division”) or any other Governmental Body in respect of such filings or such transactions, and (iii) cooperate with each other in connection with any such filing (including, to the extent permitted by applicable Law, providing copies of all such documents to the non-filing parties prior to filing and considering all reasonable additions, deletions or changes suggested in connection therewith) and in connection with resolving any investigation or other inquiry of any of the FTC, the Antitrust Division or other Governmental Body under any Antitrust Law with respect to any such filing or any such transaction. Each such party shall use commercially reasonable efforts to furnish to each other party hereto all information required for any application or other filing to be made pursuant to any applicable Law in connection with the transactions contemplated by this Agreement. Each such party shall promptly inform the other parties hereto of any oral communication with, and provide copies of written communications with, any Governmental Body regarding any such filings or any such transaction and permit the other party to review in advance any proposed communication by such party to any Governmental Body. No party hereto shall independently participate in any formal meeting with any Governmental Body in respect of any such filings, investigation, or other inquiry without giving the other parties hereto prior notice of the meeting and, to the extent permitted by such Governmental Body, the opportunity to attend and/or participate. Subject to applicable Law, the parties hereto shall consult and cooperate with one another in connection with the matters described in this Section 6.4, including in connection with any analyses, appearances, presentations, memoranda, briefs, arguments, opinions and proposals made or submitted by or on behalf of any party hereto relating to proceedings under the HSR Act or other Antitrust Laws.

(b) Each of Purchaser, the Sellers and the Companies shall use commercially reasonable efforts to resolve such objections, if any, as may be asserted by any Governmental Body with respect to the transactions contemplated by this Agreement under any Law, including the HSR Act, the Sherman Act, as amended, the Clayton Act, as amended, the Federal Trade Commission Act, as amended, that is designed to prohibit, restrict or regulate actions having the purpose or effect of monopolization or restraint of trade (collectively, the “Antitrust Laws”). In connection therewith, if any Legal Proceeding is instituted (or threatened to be instituted) challenging any transaction contemplated by this Agreement as in violation of any Law, Purchaser, the Sellers and

the Companies shall, subject to the mutual agreement of CSG and Purchaser, cooperate and use commercially reasonable efforts to contest and resist any such Legal Proceeding, and to have vacated, lifted, reversed, or overturned any decree, judgment, injunction or other order whether temporary, preliminary or permanent, that is in effect and that prohibits, prevents, or restricts consummation of the transactions contemplated by this Agreement, including by pursuing all available avenues of administrative and judicial appeal. Each of the parties shall enter into such mutual agreement unless, in its reasonable judgment, the taking of the action in question is not in its business interests. Each of Purchaser, the Sellers and the Companies shall use commercially reasonable efforts to take such action as may be required to cause the expiration of the notice periods under the HSR Act or other Antitrust Laws with respect to such transactions as promptly as possible after the execution of this Agreement. Notwithstanding anything to the contrary in this Agreement, neither Purchaser nor any of its Affiliates (which for purposes of this sentence shall include the Companies and Subsidiaries) shall be required, in connection with the matters covered by this Section 6.4, (i) to hold separate (including by trust or otherwise) or divest any of their respective businesses, product lines or assets or (ii) to agree to any limitation on the operation or conduct of the Business.

6.5 Further Assurances. Subject to, and not in limitation of, Section 6.4, each of the Companies, the Sellers and Purchaser shall use its commercially reasonable efforts to (i) take, or cause to be taken, all actions necessary or appropriate to consummate the transactions contemplated by this Agreement and (ii) cause the fulfillment at the earliest practicable date of all of the conditions to its respective obligations to consummate the transactions contemplated by this Agreement. The Sellers and Purchaser agree, and the Sellers prior to Closing, and Purchaser, after the Closing, agree to cause each Company and Subsidiary, to execute and deliver such other documents, certificates, agreements and other writings and to take such other actions as may be necessary or desirable in order to consummate or implement expeditiously the transactions contemplated by this Agreement.

6.6 Non-Solicitation and Confidentiality.

(a) For a period of eighteen (18) months from and after the Closing Date, the Sellers shall not, and shall cause their respective directors, officers, employees and Affiliates not to, directly or indirectly cause, solicit, induce or encourage any employees of the Companies or Subsidiaries or any employee of Purchaser or its Affiliates (which, for these purposes, includes the Companies and Subsidiaries) engaged primarily in the Business prior to the Closing to leave such employment or hire, employ or otherwise engage any such individual (other than through generalized searches for employees through media advertisements, employment firms or otherwise that are not focused on Persons employed by Purchaser or any of its Affiliates or their successors); provided, however, that should a Transferred Employee elect not to accept employment with Purchaser, such Transferred Employee may, with the consent of Purchaser, which consent shall not be unreasonably withheld, maintain his or her employment with Seller; provided, further, that such Transferred Employee shall be made available to Purchaser and its Affiliates as a consultant for a period of up to six (6) months following the

Closing as needed by Purchaser at cost (calculated as a percentage of base salary assuming a 40-hour work week) to be paid by Purchaser. This restriction shall not apply to any Transferred Business Employee whose employment with Purchaser or its successor is terminated by Purchaser or its successor after the Closing

(b) From and after the Closing Date, the Sellers shall not and shall cause their officers and Affiliates not to, directly or indirectly, disclose, reveal, divulge or communicate to any Person other than authorized officers, directors and employees of Purchaser or its Affiliates (which for this purpose shall include the Companies and Subsidiaries) or use or otherwise exploit for its own benefit or for the benefit of anyone other than Purchaser, any Confidential Information (as defined below). The Sellers shall not have any obligation to keep confidential (or cause their officers, directors or Affiliates to keep confidential) any Confidential Information if and to the extent disclosure thereof is specifically required by applicable Law or is generally required to reply to a request by a Governmental Authority; provided, however, that in the event disclosure is requested or required by a Governmental Authority (by requests for information or documents or subpoenas), the Sellers shall, to the extent reasonably possible, provide Purchaser with prompt notice of such requirement prior to making any disclosure so that Purchaser may seek an appropriate protective order. For purposes of this Section 6.6(b), “Confidential Information” means any information with respect to any of the Companies or Subsidiaries or otherwise primarily used in connection with the Business, including methods of operation, customer lists, products, prices, fees, costs, technology, inventions, trade secrets, know-how, software, marketing methods, plans, personnel, suppliers, competitors, markets or other specialized information or proprietary matters. “Confidential Information” does not include, and there shall be no obligation hereunder with respect to, information that (i) is generally available to the public on the date of this Agreement, (ii) becomes generally available to the public other than as a result of a disclosure not otherwise permissible hereunder, (iii) although related to the Companies or Subsidiaries and/or primarily used in connection with the Business, is also used by the Sellers or their Affiliates (other than the Companies or Subsidiaries) prior to the Closing Date or (iv) is otherwise required as expressly provided in the Ancillary Agreements.

(c) The covenants and undertakings contained in this Section 6.6 relate to matters which are of a special, unique and extraordinary character and a violation of any of the terms of this Section 6.6 will cause irreparable injury to Purchaser or any Seller, as applicable, the amount of which will be impossible to estimate or determine and which cannot be adequately compensated. Accordingly, the remedy at law for any breach of this Section 6.6 will be inadequate. Therefore, Purchaser or any Seller, as applicable, will be entitled to a temporary and permanent injunction, restraining order or other equitable relief from any court of competent jurisdiction in the event of any breach of this Section 6.6 without the necessity of proving actual damage or posting any bond whatsoever. The rights and remedies provided by this Section 6.6 are cumulative and in addition to any other rights and remedies which Purchaser or any Seller, as applicable, may have hereunder or at law or in equity.

(d) The parties hereto agree that, if any court of competent jurisdiction determines that a specified time period or any other relevant feature of this Section 6.6 is unreasonable, arbitrary or against public policy, then the maximum enforceable period of time, geographical area, business limitation or other relevant feature which is determined by such court to be reasonable, not arbitrary and not against public policy may be enforced against the applicable party.

6.7 Preservation of Records. Subject to Section 9.16 and any retention requirements relating to the preservation of Tax records, the Sellers and Purchaser agree that each of them shall (and shall cause the Companies and Subsidiaries to) preserve and keep the records held by them relating to the respective businesses of the Companies and Subsidiaries for a period of seven (7) years from the Closing Date and shall make such records and personnel available to the other as may be reasonably required by such party in connection with, among other things, any insurance claims by, legal proceedings against or governmental investigations of the Purchaser, any of the Sellers, Companies or Subsidiaries or any of their Affiliates or in order to enable the Sellers or Purchaser to comply with their respective obligations under this Agreement and each other agreement, document or instrument contemplated hereby or thereby. In the event the Sellers or Purchaser wishes to destroy (or permit to be destroyed) such records after that time, such party shall first give 60 days prior written notice to the other and such other party shall have the right at its option and expense, upon prior written notice given to such party within that 60 day period, to take possession of the records within 30 days after the date of such notice.

6.8 Publicity.

(a) None of the Purchaser, the Sellers or the Companies shall issue any press release or public announcement concerning this Agreement or the transactions contemplated hereby without obtaining the prior written approval of the other parties hereto, which approval will not be unreasonably withheld or delayed, unless disclosure is otherwise required by applicable Law or by the applicable rules of any stock exchange on which Purchaser or its Affiliates or CSG lists securities, provided that, to the extent required by applicable Law or by the applicable rules of any stock exchange, the party intending to make such release shall (i) promptly notify the other parties, and (ii) use its commercially reasonable efforts consistent with such applicable Law to consult with the other parties with respect to the text thereof and (iii) cooperate with the other parties to narrow the scope of the disclosure required to be made.

(b) Each of Purchaser, the Sellers and the Companies agrees that the terms of this Agreement shall not be disclosed or otherwise made available to the public and that copies of this Agreement shall not be publicly filed or otherwise made available to the public, except where such disclosure, availability or filing is required by applicable Law or the applicable rules of any stock exchange.

The Sellers shall give notice to Purchaser and Purchaser shall give notice to the Seller, as promptly as reasonably practicable upon becoming aware of (a) any fact, change, condition, circumstance, event, occurrence or non-occurrence that has caused or is reasonably likely to cause any representation or warranty in this Agreement made by it to be untrue or inaccurate in any material respect at any time after the date hereof and prior to the Closing, (b) any material failure on its part to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it hereunder or (c) the institution of or the threat of institution of any Legal Proceeding against any of the Companies, the Subsidiaries or the Sellers related to this Agreement or the transactions contemplated hereby; provided that the delivery of any notice pursuant to this Section 6.12 shall not limit or otherwise affect the remedies available hereunder to the party receiving such notice, or the representations or warranties of, or the conditions to the obligations of, the parties hereto.

6.13 Employees.

(a) The Side Letter sets forth the severance payable to each Business Employee if such Business Employee were a Non-Transferred Employee who will be severed by the Sellers and their Affiliates (other than the Companies and Subsidiaries) following the Closing Date and in connection with the transactions contemplated by this Agreement. Between the date hereof and the Closing, the Sellers shall promptly notify Purchaser in writing of (i) any offer of employment to any New Hire in accordance with Section 6.2(b)(v), indicating for each, the name, start date, position, job location, base salary, commission eligibility and incentive plan target and (ii) the termination of the employment or commencement of any disability or leave of absence of any Business Employee, indicating, where relevant, the term of any such approved leave of absence. Not less than 20 Business Day prior to the scheduled Closing, the Sellers shall deliver to Purchaser updates to Exhibits B, C, D and E of the Side Letter but only to the extent that such updated information, together with the information provided in clause (ii) of the preceding sentence, would not be complete and accurate as of such date. Not less than 15 days prior to the scheduled Closing, Purchaser shall, in compliance with applicable Law, identify in writing all Business Employees to be transferred to a Company or Subsidiary and indicating the applicable transferee Company or Subsidiary for each such Business Employee (the “Transfer Notice”). Not less than 10 days prior to the scheduled Closing, the Sellers shall, or shall cause their applicable Affiliates (other than the Companies and Subsidiaries) to, transfer all such Business Employees so identified by Purchaser in accordance with this Section 6.13(a) but excluding any such U.S. employees on long-term disability (the “Transferred Business Employees”), and the Sellers shall cause the transferee Companies and Subsidiaries to employ such Transferred Business Employees. Not less than 10 days prior to the scheduled Closing, the Sellers shall notify Purchaser in writing, with respect to each Non-Transferred Employee, the severance to which each such employee would be entitled upon being severed by the Sellers calculated in accordance with the severance policy set forth in Schedule 6.13(b) (the “Severance Notice”). Not less than 10 days prior to the scheduled Closing, the Sellers shall cause each applicable Company or Subsidiary to transfer all employees whose services are not

primarily dedicated to the Business, including all such employees who have rights of employment on return from any leave or other absence, and the Sellers shall, or shall cause their applicable Affiliates (other than the Companies and Subsidiaries) to, employ such employees. The Sellers and Purchaser intend that the transactions contemplated by this Agreement shall not constitute an event entitling any Transferred Business Employee to severance benefits. Immediately following the Closing Date, Purchaser shall cause each Company and each Subsidiary to continue the employment of each of their respective employees, including the Transferred Business Employees (each, a “Continuing Employee”); provided, however, that any U.S. employee of a Company or Subsidiary who as of the Closing Date is not actively at work as a result of long-term disability shall not be a Continuing Employee unless and until such employee presents himself or herself to return to work within 180 days after the Closing Date. Subject to applicable Law, nothing in this Section 6.13 shall limit the right of the Companies and Subsidiaries to dismiss any of their employees at any time and for any reason and to change the terms and conditions of their employment (including compensation and employee benefits provided to them).

(b) For a period of one (1) year after the Closing, Purchaser shall cause the applicable Company or the Subsidiary to provide to each Continuing Employee (i) annualized salary equal to 100% of the annualized base salary provided to such Employee by Seller, Company or Subsidiaries immediately prior to Closing, and (ii) a bonus opportunity and benefits provided to similarly situated employees of Purchaser. Purchaser shall provide or shall cause to be provided to any U.S. Continuing Employee whose employment is terminated during the six (6) month period following the Closing a severance payment calculated in accordance with the severance policy set forth in Schedule 6.13(b). In addition to any severance payments that may be due, if any Continuing Employee is terminated after the Closing, Purchaser will provide or cause to be provided 100% of the 2005 Annual Bonus that such Continuing Employee would have been entitled to if they had been employed as of the bonus payment date to the extent accrued and not yet paid. With respect to the Continuing Employees, each employee medical, dental, vision care and prescription drug plan, program, policy and arrangement of Purchaser shall waive any pre-existing condition exclusion (to the extent such exclusion was waived under the corresponding Benefit Plan) and any proof of insurability and shall recognize, for purposes of satisfying any deductibles, co-pays and out-of-pocket maximums during the calendar year in which the Closing occurs, any payment made towards deductibles, co-pays and out-of-pocket maximums for such calendar year under the corresponding Benefit Plan. The Sellers agree to transfer the cafeteria plan accounts and experience of Continuing Employees (to the extent applicable) to substantially equivalent plans that exist or will be established by Purchaser. The Sellers and Purchaser agree to determine the terms and conditions of such transfer. All service by a Continuing Employee with the Seller, including service with predecessor employers that was recognized by the Sellers and their Affiliates, shall be recognized by Purchaser for purposes of vacation entitlement and participation and vesting (but not for purposes of benefit accrual) under the benefits of Purchaser, including any defined benefit or defined contribution pension plans, welfare benefit plans and severance plans of Purchaser to the

same extent such service was recognized under the corresponding Benefit Plan. Purchaser will continue to provide relocation assistance to those Continuing Employees receiving it as of the Closing Date and tuition assistance to those Continuing Employees who are receiving such benefits as of the Closing Date for the academic session then in effect (the “Relocation and Tuition Benefits”) to the extent set forth in Schedule 6.13(b)(i). With respect to Continuing Employees who are on international assignment as of the Closing Date, Purchaser will provide the benefits provided under CSG’s international assignee program as in effect as of Closing, including repatriation upon completion of assignment, completion bonuses, Tax equalization and Tax Return preparation. Purchaser shall assume, or shall cause the applicable Company or Subsidiary to retain, all Liabilities with respect to, and honor the vacation, personal days and floating holidays accrued but unused by, each Continuing Employee as of the Closing, and Purchaser or any Company or Subsidiary (as the case may be) shall be solely liable for such accruals to the extent accrued on the most recent Financial Statements (the “Accrued Days”).

(c) Purchaser shall make and be responsible for the payment of all accrued but unpaid incentive compensation of each Continuing Employee for the 2005 calendar year (the “2005 Annual Bonus”).

(d) Purchaser shall cause the tax-qualified defined contribution plan established or maintained by Purchaser (“Purchaser’s Savings Plan”) to accept eligible rollover distributions (as defined in Section 402(c)(4) of the Code) from U.S. Continuing Employees with respect to any account balances distributed to them on or as of the Closing Date by the CSG Incentive Savings Plan. Rollovers of outstanding loans under the CSG Incentive Savings Plan shall be permitted. The distribution and rollover described herein shall comply with applicable Law and each party shall make all filings and take any actions required of such party under applicable Law in connection therewith. Purchaser and the Sellers agree that U.S. Continuing Employees who are participants in the CSG Incentive Savings Plan who elect to roll over their outstanding loans thereunder to Purchaser’s Savings Plan shall inform the plan administrator of the CSG Incentive Savings Plan by a predetermined date to be mutually agreed upon by Purchaser and the Sellers, and the Sellers shall cause the recordkeeper for the CSG Incentive Savings Plan to provide a data file to the plan administrator of Purchaser’s Savings Plan in a format identified by such plan administrator that includes all such participants who have elected to roll over their outstanding loans. No rollovers of outstanding loans under the CSG Incentive Savings Plan shall be accepted by Purchaser’s Savings Plan from individual participants who have not made the election by the predetermined date.

(e) The Sellers shall be responsible for and shall defend, indemnify and hold harmless Purchaser for any failure to provide health continuation coverage (including any penalties, excise taxes or interest resulting from the failure to provide continuation coverage) required by Section 4980B of the Code (i) with respect to each current or former employee of the Sellers, their Affiliates, Companies or Subsidiaries other than the Continuing Employees, due to qualifying events whenever occurring, (ii)

with respect to each Continuing Employee, due to qualifying events which occur on or before the Closing Date, and (iii) with respect to each U.S. employee of a Company or Subsidiary who as of the Closing Date is not actively at work as a result of long-term disability, due to qualifying events which occur before the date such employee presents himself or herself to return to work in accordance with Section 6.13(a). Purchaser shall be responsible for and shall defend, indemnify and hold harmless the Sellers for any failure to provide health continuation coverage (including any penalties, excise taxes or interest resulting from the failure to provide continuation coverage) required by Section 4980B of the Code with respect to each Continuing Employee due to qualifying events which occur after the Closing Date. The Sellers shall be responsible for providing any applicable COBRA notices to any Business Employee in respect of events occurring prior to such Business Employee’s transfer to a Company or Subsidiary in accordance with Section 6.13(a).

(f) Nothing in this Section 6.13 will be or be deemed to be for the benefit of or enforceable by, any Person who is not a party hereto, including, without limitation, any director, officer, employee or independent contractor of any Seller, Company or Subsidiary or their respective affiliates. Furthermore, nothing in this Section 6.13 will be or be deemed to be an amendment of a Benefit Plan.

(g) To the extent that the rights and obligations of the employees of the Companies, Subsidiaries or the Business and their respective employers (whether in respect of any Benefit Plan), are regulated by applicable Law and/or any collective bargaining agreement, the Sellers and Purchaser shall fully cooperate (and the Sellers shall cause the relevant Companies and Subsidiaries to fully cooperate with Purchaser) for the purpose of ensuring that such Laws and collective bargaining agreements are fully complied with at all times up to the Closing Date, and at any time thereafter in respect of the transactions contemplated in this Agreement. After Closing, the Sellers will provide Purchaser with information reasonably required by Purchaser and otherwise will provide Purchaser with reasonable assistance in relation to the Company Plans, including any superannuation contribution arrangements (excluding the funding of such arrangements), any of the Companies and Subsidiaries have in place as at Closing.

(h) At or prior to the Closing Date, the Sellers shall cause CSG Software to terminate the CSG Software, Inc. Wealth Accumulation Plan and to pay promptly the account balances thereunder to the participants therein in accordance with the terms thereof.

6.14 Certain Tax Matters. The Sellers shall use their reasonable best efforts to file, or caused to be filed, all Tax Returns due (taking into account any available extensions of time to file) on or before the Closing Date. CSG Netherlands shall use its reasonable best efforts to file a request for a ruling from the appropriate Tax Authority in the Netherlands that dividends paid to CSG Netherlands qualify for the participation exemption as soon as practicable, it being understood that CSG Netherlands currently intends to file a request for such a ruling on or before October 14, 2005.

Notwithstanding the foregoing and solely with respect to this Article VIII, there shall be excluded from “Losses” hereunder, and there shall be no indemnification by Sellers hereunder in respect of, any item to the extent of the amount of any Liability or reserve reflected in the Closing Working Capital Statement in respect thereof.

(c) The right to indemnification or any other remedy based on representations, warranties, covenants and agreements in this Agreement, or any Seller Documents, Company Document or Purchaser Document shall not be affected by any investigation conducted at any time, or any knowledge acquired (or capable of being

acquired) at any time, whether before or after the execution and delivery of this Agreement or the Closing Date, with respect to the accuracy or inaccuracy of, or compliance with, any such representation, warranty, covenant or agreement. The waiver of any condition based on the accuracy of any such representation or warranty, or on the performance of or compliance with any such covenant or agreements, will not affect the right to indemnification or any other remedy based on such representations, warranties, covenants and agreements.

8.3 Indemnification Procedures.

(a) A claim for indemnification for any matter not involving a third party claim may be asserted by notice to the party from whom indemnification is sought; provided, however, that failure to so notify the indemnifying party shall not preclude the indemnified party from any indemnification which it may claim in accordance with this Article VIII except to the extent such failure shall have adversely prejudiced the indemnifying party.

(b) In the event that any Legal Proceedings shall be instituted or that any claim or demand shall be asserted by any third party in respect of which indemnification may be sought under Section 8.2 hereof (regardless of the limitations set forth in Section 8.4) (a “Third Party Claim”), the indemnified party shall promptly cause written notice of the assertion of any Third Party Claim of which it has knowledge which is covered by this indemnity to be forwarded to the indemnifying party. The failure of the indemnified party to give reasonably prompt notice of any Third Party Claim shall not release, waive or otherwise affect the indemnifying party’s obligations with respect thereto except to the extent that the indemnifying party can demonstrate actual loss and prejudice as a result of such failure. Subject to the provisions of this Section 8.3, the indemnifying party shall have the right, at its sole expense, to be represented by counsel of its choice, which must be reasonably satisfactory to the indemnified party, and to defend against, negotiate, settle or otherwise deal with any Third Party Claim which relates to any Losses indemnified against hereunder. If the indemnifying party elects to defend against, negotiate, settle or otherwise deal with any Third Party Claim which relates to any Losses indemnified by it hereunder, it shall within 30 days of the indemnified party’s written notice of the assertion of such Third Party Claim (or sooner, if the nature of the Third Party Claim so requires) notify the indemnified party of its intent to do so; provided, that the indemnifying party must conduct the defense of the Third Party Claim actively and diligently thereafter in order to preserve its rights in this regard. If the indemnifying party elects not to defend against, negotiate, settle or otherwise deal with any Third Party Claim which relates to any Losses indemnified against hereunder, fails to notify the indemnified party of its election as herein provided or contests its obligation to indemnify the indemnified party for such Losses under this Agreement, the indemnified party may defend against, negotiate, settle or otherwise deal with such Third Party Claim at its own expense. If the indemnified party defends any Third Party Claim, then the indemnifying party shall reimburse the indemnified party for the expenses of defending such Third Party Claim upon submission of periodic bills. If the indemnifying party shall assume the defense of any Third Party

Claim, the indemnified party may participate, at his or its own expense, in the defense of such Third Party Claim; provided, however, that such indemnified party shall be entitled to participate in any such defense with separate counsel at the expense of the indemnifying party if (i) so requested by the indemnifying party to participate or (ii) in the reasonable opinion of counsel to the indemnified party, a conflict or potential conflict exists between the indemnified party and the indemnifying party that would make such separate representation advisable; and provided, further, that the indemnifying party shall not be required to pay for more than one such counsel for all indemnified party in connection with any Third Party Claim. The parties hereto agree to provide reasonable access to the other to such documents and information as may be reasonably requested in connection with the defense, negotiation or settlement of any such Third Party Claim. Notwithstanding anything in this Section 8.3 to the contrary, neither the indemnifying party nor the indemnified party shall, without the written consent of the other party, settle or compromise any Third Party Claim or permit a default or consent to entry of any judgment unless the claimant or claimants and such party provide to such other party an unqualified release from all Liability in respect of the Third Party Claim. If the indemnifying party makes any payment on any Third Party Claim, the indemnifying party shall be subrogated, to the extent of such payment, to all rights and remedies of the indemnified party to any insurance benefits or other claims of the indemnified party with respect to such Third Party Claim.

(c) After any final decision, judgment or award shall have been rendered by a Governmental Body of competent jurisdiction and the expiration of the time in which to appeal therefrom, or a settlement shall have been consummated, or the indemnified party and the indemnifying party shall have arrived at a mutually binding agreement, in each case with respect to a Third Party Claim hereunder, the indemnified party shall forward to the indemnifying party notice of any sums due and owing by the indemnifying party pursuant to this Agreement with respect to such matter and the indemnifying party shall pay all of such remaining sums so due and owing to the indemnified party by wire transfer of immediately available funds within five (5) Business Days after the date of such notice.

8.4 Limitations on Indemnification for Breaches of Representations and Warranties.

(a) An indemnifying party shall not have any Liability under Section 8.2(a)(i), or Section 8.2(b)(i) hereof unless the aggregate amount of Losses incurred by the indemnified parties and indemnifiable thereunder based upon, attributable to or resulting from the failure of any of the representations or warranties to be true and correct exceeds three-fourths percent (0.75%) of the Purchase Price (the “Basket”) and, in such event, the indemnifying party shall be required to pay the amount of all such Losses in excess of the Basket; provided that the Basket limitation shall not apply to Losses related to the failure to be true and correct of any of the representations and warranties set forth in the Seller Special Representations, the Seller Statute of Limitations Representation and the Purchaser Special Representations. In addition, the indemnified party shall have no recourse under this Article for any individual items where the Loss relating thereto is less

than $25,000; provided, however, that such items shall be aggregated for purposes of determining whether the Basket has been exceeded in accordance with the first sentence of this Section 8.4(a).

(b) Neither the Sellers nor Purchaser shall be required to indemnify any Person under Section 8.2(a)(i) or 8.2(b)(i) for an aggregate amount of Losses exceeding thirty percent (30%) of the Purchase Price (the “Cap”) in connection with Losses related to the failure to be true and correct of any of the representations or warranties of the Sellers or Purchaser in Articles III, IV and V, respectively; provided that there shall be no Cap with respect to Losses related to the failure to be true and correct of any of the representations or warranties contained in the Seller Special Representations, the Seller Statute of Limitations Representation and the Purchaser Special Representations.

(c) For purposes of determining the failure of any representations or warranties to be true and correct, the breach of any covenants and agreements, and calculating Losses hereunder, any materiality or Material Adverse Effect qualifications in the representations and warranties shall be disregarded.

(d) No action taken by the Sellers, the Companies or the Subsidiaries in compliance with Section 6.2(c) shall be considered for purposes of determining the whether any representations or warranties are true and correct at Closing.

(e) The representation and warranty contained in Section 4.13(b)(i) shall be deemed to be qualified by the phrase “To the Knowledge of the Sellers and the Companies” at the beginning thereof solely for purposes of determining whether the Sellers shall have Liability for Losses, subject to the other terms and conditions of this Article VIII, arising from the infringement, misappropriation or other violation of Intellectual Property rights of any third party that occurs before or after the Closing in accordance with the example set forth below. For purposes of clarity, the following example is provided: if the Sellers and the Companies had no Knowledge of a violation of the Intellectual Property rights of a third party and it is ultimately determined that such rights were violated and $100 of Losses (calculated in accordance with the balance of this Article VIII) resulted therefrom, $40 of which were attributable to pre-Closing violations and $60 of which were attributable to post-Closing violations, the Sellers would be responsible only for that portion of the Losses attributable to pre-Closing violations which would amount to $40 of such Losses. To the extent that any infringement, misappropriation or other violation of Intellectual Property rights of any third party occurs from and after the Closing solely as a result of modifications to the Intellectual Property made by Purchaser, the Sellers shall have no obligation to provide indemnification under this Article VIII.

(f) The amount of the indemnifying party’s Liability under this Agreement shall be net of any amounts recovered by the indemnified party under applicable insurance policies and other savings that have been realized by, the indemnified party. If an indemnifying party’s obligation under Section 8.2 or Article IX

arises in respect of an adjustment which makes allowable to the indemnified party, any of its Affiliates or, in the case of the Purchaser, effective upon the Closing, any Company or Subsidiary any deduction, amortization, exclusion from income or other allowance (a “Tax Benefit”) which would not, but for such adjustment, be allowable, then any payment by the indemnifying party to the indemnified party shall be an amount equal to (x) the amount otherwise due but for this subsection (d), minus (y) the present value of the Tax Benefit multiplied by the maximum federal or state, as the case may be, corporate Tax rate in effect at the time the relevant adjustment is made or, in the case of a credit, by 100 percent. The present value referred to in the preceding sentence shall be determined using a discount rate equal to the mid-term applicable federal rate in effect at the time the relevant adjustment is made and assuming that the Tax Benefit will be used at the earliest date or dates allowable by applicable Law; provided, however, that if the Tax Benefit constitutes an increase in basis of nondepreciable, nonamortizable property, it shall be taken into account only when actually realized prior to the expiration of the period provided for in Section 9.12.

(g) Notwithstanding anything to the contrary elsewhere in this Agreement, no party shall, in any event, be liable to any other Person for any consequential, incidental, indirect, special or punitive damages of such other Person, including loss of future revenue, income or profits, diminution of value or loss of business reputation or opportunity relating to the breach or alleged breach hereof; provided, that the foregoing shall not be construed to preclude recovery by the indemnified party in respect of Losses directly incurred from Third Party Claims. The Sellers and Purchaser shall each take commercially reasonable actions to mitigate their damages.

(h) From and after the Closing, except in the event of fraud (in which case the parties shall be entitled to exercise all of their rights, and seek all damages available to them, under law or equity) the sole and exclusive remedy for any breach or failure to be true and correct, or alleged breach or failure to be true and correct, of any representation or warranty or any covenant or agreement in this Agreement, shall be indemnification in accordance with this Article VIII. In furtherance of the foregoing, the parties hereby waive, to the fullest extent permitted by applicable Law, any and all other rights, claims and causes of action (including rights of contributions, if any) known or unknown, foreseen or unforeseen, which exist or may arise in the future, that it may have against the Sellers or Purchaser, as the case may be, arising under or based upon any federal, state or local Law (including any such Law relating to environmental matters or arising under or based upon any securities Law, common Law or otherwise). Notwithstanding the foregoing, this Section 8.4(g) shall not operate to interfere with or impede the operation of the provisions of Article IX or Article II providing for the (i) resolution of certain disputes relating to the Purchase Price between the parties and/or by an Arbiter and (ii) limit the rights of the parties to seek equitable remedies (including specific performance or injunctive relief).

(i) The Sellers shall have no right of contribution or other recourse against the Companies or Subsidiaries or their respective directors, officers, employees,

Affiliates, agents, attorneys, representatives, assigns or successors for any Third Party Claims asserted by Purchaser Indemnified Parties, it being acknowledged and agreed that the covenants and agreements of the Companies are solely for the benefit of the Purchaser Indemnified Parties.

(j) Purchaser Indemnified Parties shall be responsible for 25% of all Losses under Section 8.2(a)(viii) up to $1,300,000 on a proportional basis, such that the Sellers shall indemnify Purchase Indemnified Parties for 75% of Losses covered by Section 8.2(a)(viii) up to $1,300,000 and 100% of Losses in excess thereof.

The Sellers shall also (and shall cause the Companies and Subsidiaries to) timely file all other Tax Returns of or which include the Companies or any of the Subsidiaries required to be filed (taking into account any extensions) on or prior to the Closing Date and shall pay or cause to be paid any and all Taxes shown as due thereon. All Tax Returns described in this Section 9.3(a) shall be prepared in a manner consistent with prior practice unless a contrary treatment is required by applicable Law.

(b) Purchaser shall cause to be prepared and timely filed all Tax Returns (other than those Tax Returns described in Section 9.3(a)) required to be filed by the Companies and Subsidiaries after the Closing Date and, subject to the right to payment from the Sellers under Section 9.3(c), pay or cause to be paid all Taxes shown as due thereon. To the extent any Taxes shown due on any Tax Return described in this Section 9.3(b) are indemnifiable by the Seller, such Tax Return shall be prepared in a manner consistent with prior practice unless a contrary treatment is required by applicable Law, and Purchaser shall provide (or cause the Companies and Subsidiaries to provide) the Sellers with copies of such Tax Returns (or, in the case of Tax Returns that include Purchaser or any Affiliate of Purchaser other than the Companies and Subsidiaries, the portion of such Tax Returns relating to the Companies and the Subsidiaries) at least 30 days prior to the due date for filing thereof (including extensions) for the Seller’s review and approval and the Sellers shall have the right (at the Seller’s

expense) to review all work papers and procedures used to prepare any such Tax Return. The Sellers and Purchaser shall attempt in good faith to resolve any disagreements regarding such Tax Returns prior to the due date for filing. In the event that the Sellers and Purchaser are unable to resolve any dispute with respect to such Tax Return at least fifteen (15) days prior to the due date for filing, such dispute shall be resolved pursuant to Section 9.10, which resolution shall be binding on the parties. Notwithstanding the foregoing, nothing contained in this Section 9.3 shall in any manner terminate, limit or adversely affect any right of the Purchaser Indemnified Parties, the Sellers or the Companies and Subsidiaries to receive indemnification pursuant to any provision in this Agreement.

(c) Not later than three (3) days prior to the due date for the payment of Taxes (including extensions) on any Tax Returns which Purchaser has the responsibility to file or cause to be filed pursuant to Section 9.3(b), the Sellers shall pay to Purchaser an amount equal to that portion of the Taxes shown on such return for which the Sellers have an obligation to indemnify the Purchaser Indemnified Parties pursuant to the provisions of Section 9.1. No payment pursuant to this Section 9.3(c) shall excuse the Sellers from their indemnification obligations pursuant to Section 9.1 if the amount of Taxes as ultimately determined (on audit or otherwise) for the periods covered by such Tax Returns exceeds the amount of the Seller’s payment under this Section 9.3(c).

9.4 Straddle Period Tax Allocation. The parties acknowledge that, for federal income Tax purposes, the taxable year of the Companies and Subsidiaries that are U.S. corporations will end as of the close of the Closing Date. With respect to all other Taxes, the Sellers and Purchaser will, unless prohibited by applicable Law, take such actions as may be required to close the taxable period of the Companies and Subsidiaries as of the close of the Closing Date. In any case where applicable Law does not permit any Company or Subsidiary to close its taxable year as of the close of the Closing Date or in any case in which a Tax is assessed with respect to a taxable period which includes the Closing Date (but does not end on that day) (a “Straddle Period”), then Taxes, if any, attributable to the taxable period of the Companies and Subsidiaries beginning before and ending after the Closing Date shall be allocated (i) to the Sellers for the period up to and including the Closing Date, and (ii) to Purchaser for the period subsequent to the Closing Date. Any allocation of income or deductions required to determine any Taxes attributable to any period beginning before and ending after the Closing Date shall be made (A) in the case of income Taxes or Taxes based on or related to income or receipts or any sales or use Tax, by means of a closing of the books and records of the applicable Company or Subsidiary as of the close of the Closing Date, provided that exemptions, allowances or deductions that are calculated on an annual basis (including, but not limited to, depreciation and amortization deductions) shall be allocated between the period ending on the Closing Date and the period after the Closing Date in proportion to the number of days in each such period and (B) in the case of other Taxes, on a per diem basis. All determinations necessary to give effect to the allocation set forth in the foregoing clause (A) shall be made in a manner consistent with the past practice of the relevant Companies and the Subsidiaries.

9.5 Tax Audits and Indemnification Procedures.

(a) If notice of any legal proceeding with respect to Taxes of any of the Companies or Subsidiaries (a “Tax Claim”) shall be received by either the Sellers or Purchaser for which the other party may reasonably be expected to be liable pursuant to Section 9.1 or 9.2 respectively, the notified party, within 30 days after receipt of such written notice, shall notify such other party in writing of such Tax Claim; provided, however, that the failure of the notified party to give the other party notice as provided herein shall not relieve such other party of its obligations under this Article IX except to the extent that such other party is actually prejudiced thereby.

(b) Purchaser shall have the right, at the expense of the Sellers to the extent such Tax Claim is subject to indemnification by the Sellers pursuant to Section 9.1 hereof, to represent the interests of the Companies and Subsidiaries in any Tax Claim (other than Tax Claims arising out of Tax Returns referred to in Section 9.3(a) and Tax Claims relating exclusively to Pre-Closing Tax Periods), provided that the Purchaser shall not settle any such claim without the consent of the Seller, which consent shall not be unreasonably withheld. If Purchaser elects to represent the interests of the Companies or Subsidiaries with respect to any Tax Claim described in this Section 9.5(b), the Sellers may, at their own expense, participate in the defense of such claim.

(c) The Sellers shall have the right to represent the Companies and Subsidiaries with respect to any Tax Claim arising out of a Tax Return referred to in Section 9.3(a) and any Tax Claim relating exclusively to a Pre-Closing Tax Period; provided, however, if the result of such Tax Claim involves an issue that recurs in taxable periods of the Companies or Subsidiaries ending after the Closing Date or otherwise could materially adversely affect Purchaser or any of the Companies or Subsidiaries for any taxable period ending after the Closing Date, then there shall be no settlement with respect thereto without the consent of Purchaser, which consent will not be unreasonably withheld.

(d) The Sellers may discharge, at any time, their indemnification obligation under Section 9.1 by paying to the Purchaser the full amount at issue and payable as of the date of such payment pursuant to Section 9.1, calculated on the date of such payment.

9.6 Termination of Tax Allocation Agreements. Any and all Tax allocation or Tax sharing agreements or other agreements or arrangements relating to Tax matters between any of the Companies or Subsidiaries on the one hand, and the Sellers or any of their Affiliates, on the other hand, shall be terminated as of the Closing Date and, from and after the Closing Date, none of the Companies, the Subsidiaries, the Sellers or any Affiliate of the Sellers shall have any further rights or liabilities pursuant to any such agreement or arrangement for any past or future period.

9.7 Carrybacks. Following the Closing Date, Purchaser, the Companies and Subsidiaries shall, to the extent permissible under applicable Law, waive

the right to carryback any income Tax losses, credits or similar items attributable to the Companies and Subsidiaries from a taxable period (or portion thereof) beginning after the Closing Date to a taxable period beginning before the Closing Date.

9.8 338 Elections.

(a) Section 338(g) Election. The Sellers acknowledge that Purchaser may make an election under Section 338(g) of the Code and any corresponding or similar elections under state, local or foreign tax law with respect to any of the Companies and Subsidiaries that is not a U.S. corporation. Purchaser shall provide the Sellers with notice of any such election as required by the Treasury Regulations under Section 338 of the Code.

(b) Section 338(h)(10) Election.

(i) CSG shall, or shall cause its Affiliates to (as the case may be), join with Purchaser in making an election under Section 338(h)(10) of the Code and the Treasury Regulations and any corresponding or similar elections under state, local or foreign tax law (collectively, the “Section 338(h)(10) Election”) with respect to any of the Companies and Subsidiaries that is a U.S. corporation.

(ii) Subject to this Section 9.8, Purchaser shall be responsible for the preparation and filing of all forms and documents required in connection with the Section 338(h)(10) Election . In addition to the Form 8023, the Sellers shall execute (or cause to be executed) and deliver to Purchaser such additional documents or forms as are reasonably requested to complete properly the Section 338(h)(10) Election at least 30 days prior to the date such Section 338(h)(10) Election is required to be filed.

(iii) Purchaser and the Sellers shall file, and shall cause their Affiliates to file, all Tax Returns and statements, forms and schedules in connection therewith in a manner consistent with the Section 338(h)(10) Election and shall take no position contrary thereto unless required to do so by applicable Law.

(iv) The parties agree that they shall retain Standard & Poor’s Corporate Value Consulting (at the expense of Purchaser except that $25,000 of such expenses shall be paid by the Sellers) to (A) allocate the Purchase Price and any other items that are treated as additional purchase price among the Companies and Subsidiaries based on the fair market value of their respective assets and liabilities and (B) provide a separate fair market valuation of the Business Intellectual Property owned by the Companies and Subsidiaries. Purchaser and the Sellers shall allocate the Purchase Price in accordance with Standard & Poor’s Corporate Value Consulting’s determinations and all Tax Returns and reports filed by Purchaser, the Sellers, and their respective Affiliates (including, but not limited to, Tax Returns required by Treasury Regulations promulgated under

Sections 338 and 1060 of the Code) shall be prepared consistently with such allocation.

9.9 Transfer Taxes. All documentary, sales, use, value added, transfer, stamp and similar Taxes, fees or governmental charges as levied by any Governmental Body (including any interest and penalties) in connection with the purchase and sale of stock or assets contemplated by this Agreement shall be borne and paid equally by Purchaser and the Seller. Purchaser will file all necessary Tax Returns with respect to such Taxes, fees or governmental charges, and, if required by applicable law, the Sellers will, and will cause their Affiliates to, join in the execution of any such Tax Returns. The Sellers and Purchaser shall cooperate with each other and use reasonable efforts to obtain any available mitigation, reduction or exemption for any such Taxes, fees or governmental charges.

9.10 Disputes. Any dispute as to any matter covered by Article IX shall be resolved by the Arbiter. The fees and expenses of the Arbiter shall be borne one-half by the Sellers and one-half by Purchaser. If any dispute with respect to a Tax Return is not resolved prior to the due date (including all available extensions) of such Tax Return, such Tax Return shall be filed in the manner which the party responsible for preparing such Tax Return deems correct; provided, however, that if the Arbiter subsequently determines that the other party’s position with respect to the dispute is correct, such other party’s indemnification obligation with respect to such Tax Return pursuant to Section 9.1 or 9.2, as the case may be, shall not exceed the amount such other party would have had to pay with respect to such Tax Return pursuant to Section 9.1 or 9.2, as the case may be, if such Tax Return had been prepared in the manner proposed by such other party. If, as a result of the previous sentence, such other party has paid an amount in excess of its indemnification obligation, the party responsible for filing such Tax Return shall promptly pay to the other party the amount of such excess.

9.11 Treatment of Indemnity Payments. The Sellers and Purchaser agree to treat any indemnity payments made pursuant to Articles VIII and IX as an adjustment to the Purchase Price for all income tax purposes. If, notwithstanding the treatment required by the preceding sentence, any indemnification payment under Article VIII or Article IX is finally determined to be taxable to the party receiving such payment by any Taxing Authority, the indemnifying party shall pay an amount that reflects the hypothetical Tax consequences of the receipt of accrual of such payment , using the maximum statutory rate (or rates, in the case of an item that affects more than one tax) applicable to the recipient of such payment for the relevant year, reflecting for example, the effect of deductions available for interest paid or accrued and for Taxes such as state and local income Taxes.

9.12 Time Limits. Any claim for indemnity under this Article IX may be made at any time prior to thirty (30) days after the expiration of the applicable Tax statute of limitations with respect to the relevant taxable period (including all periods of extension, whether automatic or permissive).

9.13 Exclusivity. Except to the extent provided in Section 8.4(f), the indemnification provided for in this Article IX shall be the sole remedy for any claim in respect of Taxes, including any claim arising out of or relating to a breach of Section 4.15. In the event of a conflict between the provisions of this Article IX, on the one hand, and the provisions of Article VIII, on the other, the provisions of this Article IX shall control.

9.14 Purchaser Covenants. Without the consent of the Sellers, which consent shall not be unreasonably withheld, Purchaser covenants that it will not cause or permit the Companies, the Subsidiaries or any Affiliate of Purchaser (i) other than as contemplated by this Agreement, to take any action on the Closing Date other than in the Ordinary Course of Business, including but not limited to the distribution of any dividend or the effectuation of any redemption that could give rise to any Tax liability or reduce any Tax asset of the Sellers or their Affiliates or give rise to any loss of the Sellers or their Affiliates under this Agreement, or (ii) except as required by Law, to amend any Tax Return that includes all or any portion of a Pre-Closing Taxable Period, take any position on any Tax Return, or enter into any agreement with any Taxing Authority, that results in an increased Tax Liability of the Sellers or their Affiliates (or a reduction of any Tax asset that would have otherwise been retained by the Sellers or their Affiliates (other than the Companies and Subsidiaries)) in respect of a Pre-Closing Taxable Period.

9.15 Refunds and Tax Benefits. Purchaser shall promptly pay or cause to be paid to the Sellers all refunds of Taxes and interest thereon received by Purchaser, any Affiliate of Purchaser, any Company or any Subsidiary attributable to Taxes paid by the Sellers, any Company or any Subsidiary (or any predecessor or Affiliate of the Seller) with respect to any taxable period (or portion thereof) ending on or before the Closing Date, except to the extent that such refunds are reflected in the calculation of Closing Working Capital. If, in lieu of receiving any such refund, any Company or Subsidiary reduces a Tax liability with respect to any taxable period (or portion thereof) beginning after the Closing Date, or increases a Tax asset that can be carried forward to any taxable period (or portion thereof) beginning after the Closing Date, Purchaser shall promptly pay or cause to be paid to the Sellers the amount of such reduction in Tax liability or the amount of any benefit resulting from such increase in Tax assets, as the case may be.

9.16 Cooperation on Tax Matters. Purchaser and the Sellers agree to furnish or cause to be furnished to each other, upon request, as promptly as practicable, such information (including access to books and records) and assistance relating to the Companies and Subsidiaries as is reasonably necessary for the filing of any return (including any report required pursuant to Section 6043A of the Code and all Treasury Regulations promulgated thereunder), for the preparation for any audit, and for the prosecution or defense of any claim, suit or proceeding relating to any proposed adjustment. Purchaser and the Sellers agree to retain or cause to be retained all books and records pertinent to the Companies and the Subsidiaries until the applicable period for assessment under applicable law (giving effect to any and all extensions or waivers) has expired, and to abide by or cause the abidance with all record retention agreements entered into with any Taxing Authority. Each Company agrees to give the Sellers

reasonable notice prior to transferring, discarding or destroying any such books and records relating to Tax matters and, if the Sellers so request, the Company shall allow the Sellers to take possession of such books and records. Purchaser and the Sellers shall cooperate with each other in the conduct of any audit or other proceedings involving the Company for any Tax purposes and each shall execute and deliver such powers of attorney and other documents as are necessary to carry out the intent of this subsection.

ARTICLE X

TERMINATION

10.1 Termination of Agreement. This Agreement may be terminated prior to the Closing as follows:

(a) At the election of the Sellers or Purchaser on or after January 31, 2006 (such date, as it may be extended, the “Termination Date”), if the Closing shall not have occurred by the close of business on such date, provided that the terminating party is not in material default of any of its obligations hereunder.

(b) by mutual written consent of the Sellers and Purchaser;

(c) by the Sellers or Purchaser if there shall be in effect a final nonappealable Order of a Governmental Body of competent jurisdiction restraining, enjoining or otherwise prohibiting the consummation of the transactions contemplated hereby; it being agreed that, subject to the last sentence of Section 6.4(b) hereof, the parties hereto shall promptly appeal any adverse determination which is not nonappealable (and pursue such appeal with reasonable diligence); provided, however, that the right to terminate this Agreement under this Section 10.1(c) shall not be available to a party if such Order was primarily due to the failure of such party to perform any of its obligations under this Agreement;

(d) by Purchaser if the Sellers or any Company shall have breached or failed to perform any of its representations, warranties, covenants or agreements set forth in this Agreement, or if any representation or warranty of the Sellers or any Company shall have become untrue, in either case such that the conditions set forth in Sections 7.2(a) or 7.2(b) would not be satisfied and such breach is incapable of being cured or, if capable of being cured, shall not have been cured within thirty (30) days following receipt by the Sellers of notice of such breach from Purchaser; or

(e) by the Sellers if Purchaser shall have breached or failed to perform any of its representations, warranties, covenants or agreements set forth in this Agreement, or if any representation or warranty of Purchaser shall have become untrue, in either case such that the conditions set forth in Sections 7.3(a) or 7.3(b) would not be satisfied and such breach is incapable of being cured or, if capable of being cured, shall not have been cured within thirty (30) days following receipt by Purchaser of notice of such breach from the Seller.

10.2 Procedure Upon Termination. In the event of termination and abandonment by Purchaser or the Seller, or both, pursuant to Section 10.1, written notice thereof shall forthwith be given to the other party or parties, and this Agreement shall terminate, and the purchase of the Securities hereunder shall be abandoned, without further action by Purchaser, the Companies or the Seller.

10.3 Effect of Termination. In the event that this Agreement is validly terminated as provided herein, then each of the parties shall be relieved of their duties and obligations arising under this Agreement after the date of such termination and such termination shall be without Liability to Purchaser, the Sellers or any Company; provided, however, that the obligations of the parties set forth in this Section 10.3, Article XI, Section 6.6(b) and Section 6.8 hereof shall survive any such termination and shall be enforceable hereunder; provided further, however, that nothing in this Section 10.3 shall relieve Purchaser, the Sellers or any Company of any Liability for a breach of this Agreement prior to the effective date of termination.

ARTICLE XI

MISCELLANEOUS

11.1 Expenses. Except as otherwise provided in this Agreement, the Sellers and Purchaser shall each bear its own expenses incurred in connection with the negotiation and execution of this Agreement and each other agreement, document and instrument contemplated by this Agreement and the consummation of the transactions contemplated hereby and thereby, it being understood that in no event shall the Companies or Subsidiaries bear any of such costs and expenses. Notwithstanding the foregoing, the Sellers and Purchaser shall each be responsible for one-half of the filing fees lawfully payable to or at the request of any Governmental Body in connection with this Agreement.

11.2 Specific Performance. The Sellers acknowledge and agree that a breach of this Agreement would cause irreparable damage to Purchaser and that Purchaser will not have an adequate remedy at law. Therefore, the obligations of the Sellers under this Agreement, including the Sellers’ obligation to sell the Securities to Purchaser, shall be enforceable by a decree of specific performance issued by any court of competent jurisdiction, and appropriate injunctive relief may be applied for and granted in connection therewith. Such remedies shall, however, be cumulative and not exclusive and shall be in addition to any other remedies which any party may have under this Agreement or otherwise.

11.3 Submission to Jurisdiction; Consent to Service of Process; Waiver of Jury Trial.

(a) The parties hereto hereby irrevocably submit to the non-exclusive jurisdiction of any federal or state court located within the State of New York over any dispute arising out of or relating to this Agreement or any of the transactions

contemplated hereby and each party hereby irrevocably agrees that all claims in respect of such dispute or any suit, action proceeding related thereto may be heard and determined in such courts. The parties hereby irrevocably waive, to the fullest extent permitted by applicable law, any objection which they may now or hereafter have to the laying of venue of any such dispute brought in such court or any defense of inconvenient forum for the maintenance of such dispute. Each of the parties hereto agrees that a judgment in any such dispute may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law.

(b) Each of the parties hereto hereby consents to process being served by any party to this Agreement in any suit, action or proceeding by delivery of a copy thereof in accordance with the provisions of Section 11.6.

(c) THE PARTIES TO THIS AGREEMENT EACH HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION, OR CAUSE OF ACTION (i) ARISING UNDER THIS AGREEMENT OR (ii) IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES HERETO IN RESPECT OF THIS AGREEMENT OR ANY OF THE TRANSACTIONS RELATED HERETO, IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER IN CONTRACT, TORT, EQUITY, OR OTHERWISE. THE PARTIES TO THIS AGREEMENT EACH HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION, OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY AND THAT THE PARTIES TO THIS AGREEMENT MAY FILE AN ORIGINAL COUNTERPART OF A COPY OF THIS AGREEMENT WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE PARTIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY.

11.4 Entire Agreement; Amendments and Waivers. This Agreement (including the schedules and exhibits hereto), the Seller Documents, the Purchaser Documents and the Side Letter represent the entire understanding and agreement between the parties hereto with respect to the subject matter hereof and can be amended, supplemented or changed, and any provision hereof can be waived, only by written instrument making specific reference to this Agreement signed by the party against whom enforcement of any such amendment, supplement, modification or waiver is sought. No action taken pursuant to this Agreement, including any investigation by or on behalf of any party, shall be deemed to constitute a waiver by the party taking such action of compliance with any representation, warranty, covenant or agreement contained herein. The waiver by any party hereto of a breach of any provision of this Agreement shall not operate or be construed as a further or continuing waiver of such breach or as a waiver of any other or subsequent breach. No failure on the part of any party to exercise, and no delay in exercising, any right, power or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of such right, power or remedy by such party preclude any other or further exercise thereof or the exercise of any other right,

power or remedy. All remedies hereunder are cumulative and are not exclusive of any other remedies provided by law.

11.5 Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of New York applicable to contracts made and performed in such state.

11.6 Notices. All notices and other communications under this Agreement shall be in writing and shall be deemed given (i) when delivered personally by hand (with written confirmation of receipt), (ii) when sent by facsimile (with written confirmation of transmission) or (iii) one Business Day following the day sent by overnight courier (with written confirmation of receipt), in each case at the following addresses and facsimile numbers (or to such other address or facsimile number as a party may have specified by notice given to the other party pursuant to this provision):
