For the avoidance of doubt, Buyer shall have the right, in its sole discretion, to designate any Acquired Asset (including any Required Interconnection Agreement) as a Non-Transferred Asset. During the period that the Non-Transferred Assets are held by Sellers, Buyer will provide management services to Sellers pursuant to the Operating Agreement.

With respect to assets that are designated by Buyer as Non-Transferred Assets and which are not subject to obtaining any further consents after the Closing, such Non-Transferred Assets shall be transferred to Buyer and Buyer will assume all related Assumed Liabilities, within five

(5) Business Days of Buyer’s written request, at which time Sellers will deliver a xxxx of sale and the requirements of Section 3.1 below shall have been deemed to be satisfied as if such Non-Transferred Assets had otherwise been transferred to Buyer at the Closing. In addition, Non-Transferred Assets shall include all of the Seller Marks, which shall be licensed to Buyer upon the Closing as set forth in the Operating Agreement. After the expiration or termination of the Operating Agreement, upon the written request of Buyer, all right, title and interest in and to the Seller Marks shall be transferred to and vest in Buyer.

2.6 Contract Assignment. Notwithstanding any provision to the contrary herein, Buyer and Sellers agree that there shall be excluded from the Acquired Assets any Assumed Contract that is not assignable or transferable pursuant to the Bankruptcy Code without the consent of any Person other than Sellers or any Affiliate of Sellers, to the extent that such consent shall not have been given on or prior to the Closing; provided, however, that Sellers shall use commercially reasonable efforts (including prosecution of appropriate motions pursuant to Section 365 of the Bankruptcy Code) to endeavor to obtain all necessary consents to the assignment thereof, and, upon obtaining the requisite consents thereto, such Acquired Asset shall be assigned to Buyer. Notwithstanding any provision to the contrary herein, Buyer and Sellers agree that all reasonable out-of-pocket costs and expenses (other than Cure Amounts) incurred relating to Sellers’ assignment to Buyer of the Assumed Contracts set forth on Schedule 2.6 of the Disclosure Schedules shall be shared equally between Buyer on the one hand and Sellers on the other hand.

If Buyer gives such notice, the membership interests in such limited liability companies shall be deemed Acquired Assets hereunder and Buyer shall acquire such membership interests at the Closing without the payment of any additional consideration. Buyer shall be permitted to give one or more notices pursuant to this Section 2.7. In addition, at Buyer’s option, a similar procedure will apply to any Equipment or other Acquired Assets which constitutes a Non-Transferred Asset. Fifty percent (50%) of all reasonable out-of-pocket costs and expenses incurred in connection with Sellers’ performance of this Section 2.7 shall be borne by each of Buyer on the one hand and Sellers on the other hand.

(a) Not less than five (5) Business Days prior to the Early Funding Date, Sellers will prepare and deliver to Buyer a good faith estimate of the Net Working Capital as of the close of business on the day immediately preceding the Early Funding Date (the “Estimated Early Funding Date Working Capital”). Sellers will prepare the Estimated Closing Working Capital in accordance with GAAP and consistent with ATI’s preparation of its unaudited balance sheet as of September 30, 2003.

(b) As promptly as practicable, but no later than sixty (60) Business Days after the Early Funding Date, Buyer will prepare and deliver to ATI a good faith calculation of Net Working Capital as of the Early Funding Date (the “Early Funding Date Working Capital”). Buyer will prepare the Early Funding Date Working Capital in accordance with GAAP and consistent with ATI’s preparation of its unaudited balance sheet as of September 30, 2003. Attached as Exhibit G is a schedule showing the calculation of Base Working Capital.

(c) If Sellers disagree with Buyer’s calculation of Early Funding Date Working Capital, Sellers may, within fifteen (15) Business Days after delivery by Buyer of the statement pursuant to Section 3.4(b), deliver a notice to Buyer disagreeing with such calculation and setting forth Sellers’ calculation of such amount. Any such notice of disagreement shall specify those items or amounts as to which Sellers disagree, and Sellers shall be deemed to have agreed with all other items and amounts contained in the calculation of the Early Funding Date Working Capital. If Sellers do not raise any objections to the Early Funding Date Working Capital within the period described herein, the Early Funding Date Working Capital will become final and binding upon Buyer and Sellers.


	(d) If a notice of disagreement shall be duly delivered pursuant to Section 3.4(c), Buyer and Sellers shall, during the fifteen (15) days following such delivery, use their commercially reasonable efforts to reach agreement on the disputed items or amounts in order to determine, as may be required, the amount of

Early Funding Date Working Capital. If during such period, Buyer and Sellers are unable to reach such agreement, they shall promptly thereafter cause representatives from the Dallas office of Ernst & Young LLP (or, if the Dallas office of Ernst & Young LLP is not independent of Buyer and Sellers, then an alternative “Big Four” accounting firm mutually agreeable to Buyer and Sellers) which representatives have not been engaged or employed within the past five (5) years by Buyer, Sellers or any of their Affiliates (or, if Sellers and Buyer agree to another nationally recognized independent accounting firm, such other firm) (the “Accounting Referee”) to review this Agreement and the disputed items or amounts for the purpose of calculating Early Funding Date Working Capital (it being understood that in making such calculation, the Accounting Referee shall be functioning as an expert and not as an arbitrator). In making such calculation, the Accounting Referee shall consider only those items or amounts as to which the parties have disagreed. The Accounting Referee shall deliver to Buyer and Sellers, as promptly as practicable (but in any case no later than thirty (30) days from the date of engagement of the Accounting Referee), a report setting forth such calculation. Such report shall be final and binding upon Buyer and Sellers. The cost of such review and report shall be borne by Buyer and Sellers in the reverse proportion that the aggregate dollar amounts of disputed items which are resolved in favor of Buyer or Sellers (as applicable) bears to the aggregate dollar amount of all disputed items resolved by the Accounting Referee.


	(e) Buyer and Sellers shall, and shall cause their respective Representatives to, cooperate and assist in the calculation of Early Funding Date Working Capital and in the conduct of the review referred to in Section 3.4(d), including providing reasonable and timely access to the books, records, work papers and personnel involved in preparing these calculations.

(f) If Estimated Early Funding Date Working Capital (i) exceeds Base Working Capital, then at the Early Funding Date, Buyer shall pay into the Adjustment Escrow Account an additional amount of cash equal to such excess or (ii) is less than Base Working Capital, then the Cash Purchase Price will be reduced by an amount equal to such deficiency. Any adjustment pursuant to this Section 3.4(f) is referred to herein as the “Initial Working Capital Adjustment.”

(g) If Final Working Capital equals Estimated Early Funding Date Working Capital, and if no further payments are or may become due pursuant to Section 3.6 hereof, then within three (3) Business Days of the later of the Closing Date or the final determination of such amount pursuant to this Section 3.4, Buyer and Sellers shall deliver a joint written notice to the Adjustment Escrow Agent pursuant to the Adjustment Escrow Agreement instructing the Adjustment Escrow Agent to pay the Adjustment Escrow Amount plus the accrued interest on such amount (by wire transfer of immediately available funds) to Sellers.


	(h) If Final Working Capital exceeds Estimated Early Funding Date Working Capital, then within three (3) Business Days of the later of the Closing Date or the final determination of such amount pursuant to this Section 3.4, Buyer shall pay such amount (by wire transfer of immediately available funds) to Sellers and, if no further


	payments are or may become due pursuant to Section 3.6 hereof, Buyer and Sellers shall deliver a written notice to the Adjustment Escrow Agent pursuant to the Adjustment Escrow Agreement instructing the Adjustment Escrow Agent to pay the Adjustment Escrow Amount plus the accrued interest on such amount (by wire transfer of immediately available funds) to Sellers.

(i) If Final Working Capital is less than Estimated Working Capital, then within three (3) Business Days of the later of the Closing Date or the final determination of such amount pursuant to this Section 3.4, Sellers and Buyer shall deliver a written notice to the Adjustment Escrow Agent pursuant to the Adjustment Escrow Agreement instructing the Adjustment Escrow Agent to pay such deficit amount plus the accrued interest thereon out of the Adjustment Escrow Account (by wire transfer of immediately available funds) to Buyer; provided that the Adjustment Escrow Account shall be the sole source of payment for any such deficiency and in no event shall Sellers be otherwise liable for any such deficiency. To the extent any Adjustment Escrow Amount remains after payment of any such deficit, and if no further payments are or may become due pursuant to Section 3.6 hereto, Buyer and Sellers shall deliver a written notice to the Adjustment Escrow Agent pursuant to the Adjustment Escrow Agreement instructing the Adjustment Escrow Agent to pay the remaining Adjustment Escrow Amount plus the accrued interest on such amount (by wire transfer of immediately available funds) to Sellers. For purposes of this Agreement, “Final Working Capital” means Early Funding Date Working Capital (i) as shown in Buyer’s calculation delivered pursuant to Section 3.4(b) if no notice of disagreement with respect thereto is duly delivered pursuant to Section 3.4(c); or (ii) if such a notice of disagreement is delivered, (A) as agreed by Buyer and Sellers pursuant to Section 3.4(a) or (B) in the absence of such agreement, as shown in the Accounting Referee’s calculation delivered pursuant to Section 3.4(a).


	(j) Any adjustment under this Section 3.4 shall be treated as an adjustment to the Purchase Price for federal, state and local income Tax purposes.

3.5 Cure Price Adjustment.

(a) The Cure Amounts, if any, as determined by the Bankruptcy Court, necessary to cure all defaults, if any, under Allegiance’s interconnection agreements with incumbent local exchange carriers (“ILECs”), together with any other payments made to settle pre-Petition disputes between any of Sellers or the Operating Subsidiaries and ILECs under such agreements, under tariffs or otherwise after the date hereof (the “ILEC Cure Amounts”) shall be resolved in accordance with this Section 3.5(a). Buyer and Sellers shall work cooperatively and in good faith with respect to paying, objecting to and settling the ILEC Cure Amounts, it being understood that all pre-Petition accounts receivable of Sellers or the Operating Subsidiaries owed by ILECs (the “ILEC Set Off Amounts”) shall be set off against the ILEC Cure Amounts and thereby used as currency to pay the ILEC Cure Amounts. Sellers shall pay all ILEC Cure Amounts (whether in cash or by application of the ILEC Set Off Amounts). Buyer and Sellers agree that subject to this Section 3.5(a), Buyer should have standing in


	the Cases with regard to ILEC Cure Amounts and the parties shall take such position in the Cases.

Notwithstanding anything herein to the contrary (including Section 6.1(k)), prior to the Sale Order Approval Date, as between Buyer and Sellers, Sellers shall have sole control over their business relationships, including without limitation, the exclusive right to negotiate and settle with the ILECs, and shall be permitted to terminate, adopt and amend interconnection agreements but shall not prior to such time settle any ILEC Cure Amounts in a manner which would be injurious in any material respect to Buyer without Buyer’s consent (which will not be unreasonably withheld) or take any action (including as specified above) if the intent or reasonably anticipated consequence thereof is or would be to injure in any material respect to Buyer’s continuing relationship with such ILEC after the Closing Date. Buyer shall be permitted to participate in any such negotiations and shall be kept reasonably informed by Sellers of the process.

(b) If deposits are required by ILECs in connection with establishing new interconnection agreements for the Business between the date hereof and the Early Funding Date and such deposits are outstanding at the time of the Early Funding Date, the Cash Purchase Price shall be increased by an amount (the “Deposit Adjustment Amount”) equal to seventy-five percent (75%) of the first $13 million of such deposits and one hundred percent (100%) of the deposits above $13 million.

(c) The Cure Amounts, if any, as determined by the Bankruptcy Court, necessary to cure all defaults, if any, under the Assumed Contracts, other than the ILEC Cure Amounts (the “Non-ILEC Cure Amounts”) shall be resolved in accordance with this Section 3.5(c). Buyer and Sellers shall work cooperatively and in good faith with respect to paying, objecting to and settling the Non-ILEC Cure Amounts, it being understood that all pre-Petition accounts receivable of Sellers and the Operating Subsidiaries owed by non-ILECs (the “Non-ILEC Set Off Amounts”) shall be set off against the Non-ILEC Cure Amounts and thereby used as currency to pay the Non-ILEC Cure Amounts. Buyer and Sellers agree that given this Section 3.5(c), Buyer should have standing in the Cases with regard to Non-ILEC Cure Amounts and the parties shall take such position in the Cases. The treatment of the Non-ILEC Cure Amounts and all matters related thereto under the Bankruptcy Plan shall be reasonably acceptable to Buyer. Sellers shall pay all Non-ILEC Cure Amounts (whether in cash or by application of the Non-ILEC Set Off Amounts); provided that if the Non-ILEC Cure Amounts are more than $11 million, the Cash Purchase Price shall be increased by an amount equal to the lesser of (A) two-thirds of the amount by which the Non-ILEC Cure Amounts exceed $11 million and (B) $8 million.

The adjustment to the Cash Purchase Price pursuant to this Section 3.5(c) is referred to herein as the “Non-ILEC Cure Adjustment.” If as of the time of the Early Funding Date any reserves are established with respect to disputed Non-ILEC Cure Amounts pending resolution of such disputes, the Purchase Price adjustment provided in this Section 3.5(c) shall be made, with respect to the agreed Non-ILEC Cure Amounts, at the Early Funding Date, and with respect to any such reserved amounts, within two (2) Business Days following the resolution of the disputes.

(d) Subject to Section 8.3, (i) on February 13, 2004, Buyer designated the (A) Real Property Leases identified on Schedule 4.21 of the Disclosure Schedules and (B) other Executory Contracts that are designated with an asterisk on Schedule 4.20 that are to be assumed by Allegiance and not rejected pursuant to section 365 of the Bankruptcy Code and (ii) at least (20) days prior to the date of the Bankruptcy Court’s confirmation of the Bankruptcy Plan, Buyer shall designate other Executory Contracts that are to be assumed by Allegiance and not rejected pursuant to section 365 of the Bankruptcy Code (collectively, the “Assumed Contracts List”) (those Contracts ultimately set forth on the Assumed Contracts List and as Additional Assumed Contracts pursuant to Section 8.3, if applicable are referred to herein as the “Assumed Contracts”). Such assumption and, in the case of Assumed Contracts to which either Seller is a party, assignment by Sellers shall be made at the Closing; provided, however, that the assignment to Buyer of any Assumed Contract related to Non-Transferred Assets shall occur on the later of (i) the Closing or (ii) State PUC Consent or FCC Consent, as applicable. At Buyer’s discretion, Allegiance agrees to assume or reject any Executory Contract, in whole or in part, to the extent portions of such Executory Contracts are severable. Buyer and Sellers agree to keep confidential and not disclose to anyone except (x) legal counsel for the Creditors Committee in the Cases and the agent to Sellers’ senior lenders, provided, that, such counsel and agent have executed confidentiality agreements reasonably acceptable to Buyer and Sellers prior to such disclosure and (y) as otherwise required by Law, the Executory Contracts that are identified by Buyer as Assumed Contracts.

3.6 Performance Price Adjustment.

(a) At least two (2) Business Days prior to the Early Funding Date, ATI shall prepare and deliver to Buyer a certificate setting forth the following: (i) total Retail Ending Lines as determined by ATI in accordance with past custom and practice, as of the last day of the last full calendar month prior to the date of the Early Funding Date plus Scheduled Future Installs less Scheduled Future Disconnects as of such day (“Total Retail Net Ending Lines”) and (ii) total gross end user revenue for the last full calendar month prior to the date of the Early Funding Date (the “Total Gross End User Revenue”). The Purchase Price shall be reduced by the greater of the following (the “Performance Adjustment Amount”): (x) the product of $625.00 and the amount, if any, by which the Total Retail Net Ending Lines for Allegiance’s Out of Region Business is less than 730,000; and (y) the product of fifteen (15) and the amount, if any, by which Total Gross End User Revenue for Allegiance’s Out of Region Business is less than $28 million. To the extent Cash and Cash Equivalents immediately prior to the Early Funding Date exceed One Hundred Eighty Seven Million Dollars ($187,000,000), the Performance Adjustment Amount (if any) shall reduce the Cash Purchase Price. To the extent such Cash and Cash Equivalents immediately prior to the Early Funding Date are less than or equal to One Hundred Eighty Seven Million Dollars ($187,000,000), any remaining portion of the Performance Adjustment Amount shall be a reduction in the number of shares of the XO Common Stock (calculated using a $7.625 per share value). ATI’s certificate shall include a calculation of the Performance Adjustment Amount.

(b) If Buyer disagrees with the certificate delivered by ATI pursuant to Section 3.6(a) hereof, Buyer may, within thirty (30) days after Early Funding Date, deliver a notice to ATI disagreeing with the calculations contained in such certificate and setting forth Buyer’s calculations. Any such notice of disagreement shall specify those items or amounts as to which Buyer disagrees, and Buyer shall be deemed to have agreed with all other items and amounts contained in the calculation of the Performance Adjustment Amount. If Buyer does not raise any objections to the Performance Adjustment Amount within the period described herein, the Performance Adjustment Amount will become final and binding upon Buyer and Sellers (the “Final Performance Adjustment Amount”). In such event, if no further payments are or may become due pursuant to Section 3.4 hereof, ATI, ATCW and Buyer shall deliver a written notice to the Adjustment Escrow Agent pursuant to the Adjustment Escrow Agreement instructing the Adjustment Escrow Agent to pay the Adjustment Escrow Amount plus the accrued interest on such amount (by wire transfer of immediately available funds) to ATI.

(c) If a notice of disagreement shall be duly delivered pursuant to Section 3.6(b), Buyer and Sellers shall, during the five (5) days following such delivery, use their commercially reasonable efforts to reach agreement on the disputed items or amounts in order to determine, as may be required, the Final Performance Adjustment Amount. If during such period, Buyer and Sellers are unable to reach such agreement, they shall promptly thereafter cause the Accounting Referee to review the disputed items or amounts for the purpose of calculating the Final Performance Adjustment Amount (it being understood that in making such calculation, the Accounting Referee shall be functioning as an expert and not as an arbitrator). In making such calculation, the Accounting Referee shall consider only those items or amounts as to which the parties have disagreed. The Accounting Referee shall deliver to Buyer and Sellers, as promptly as practicable (but in any case no later than fifteen (15) days from the date of engagement of the Accounting Referee), a report setting forth such calculation. Such report shall be final and binding upon Buyer and Sellers. The cost of such review and report shall be borne by Buyer and Sellers in the reverse proportion that the aggregate dollar amounts of disputed items which are resolved in favor of Buyer or Sellers (as applicable) bears to the aggregate dollar amount of all disputed items resolved by the Accounting Referee.

(d) If the parties hereto agree, or the Accounting Referee determines, that the Final Performance Adjustment Amount is greater (the “Additional Amount”) than the amount set forth in ATI’s certificate delivered pursuant to Section 3.6(a), then within two (2) Business Days of such determination pursuant to this Section 3.6, Buyer and Sellers shall deliver a written notice to the Adjustment Escrow Agent pursuant to the Adjustment Escrow Agreement instructing the Adjustment Escrow Agent to pay the Additional Amount plus the accrued interest on such amount (by wire transfer of immediately available funds) to Buyer, and, if no further payments are or may become due pursuant to Section 3.4 hereof, the balance of the Adjustment Escrow Amount plus the accrued interest thereon to ATI. The Adjustment Escrow Account shall be the sole source of payment for any payment obligation of Sellers pursuant to Section 3.6.

3.7 Allocation of Purchase Price. Buyer shall, within 120 days after the Closing Date, prepare and deliver to Sellers a schedule (the “Allocation Schedule”) allocating the Purchase Price and the Assumed Liabilities among the Acquired Assets in accordance with Treasury Regulation Section 1.1060-1 (or any comparable provisions of state or local tax law) or any successor provision. ATI may propose to Buyer specific changes in the Allocation Schedule within ten (10) days of the receipt thereof. If no such changes are proposed in writing to Buyer within such time, Sellers will be deemed to have agreed to the Allocation Schedule. If such changes are proposed, Buyer and ATI will negotiate in good faith and will use their best efforts to agree upon the Purchase Price allocation. If Buyer and ATI cannot mutually resolve ATI’s reasonable objections to the Allocation Schedule within ten (10) days after Buyer’s receipt of such objections, such dispute with respect to the Allocation Schedule shall be presented to the Accounting Referee, on the next day for a decision that shall be rendered by the Accounting Referee within thirty calendar days thereafter and shall be final and binding upon each of the parties. The fees, costs and expenses incurred in connection therewith shall be shared in equal amounts by Buyer, on the one hand, and Sellers, on the other hand. Buyer and Sellers each shall report and file all Tax Returns (including amended Tax Returns and claims for refund) consistent with the Allocation Schedule, and shall take no position contrary thereto or inconsistent therewith (including in any audits or examinations by any taxing authority or any other proceedings). Buyer and Sellers shall cooperate in the filing of any forms (including Form 8594) with respect to such allocation. Notwithstanding any other provisions of this Agreement, the foregoing agreement shall survive the Closing Date.

The Employee Benefit Plans have been administered in accordance with their terms in all material respects and are in compliance with applicable Law in all material respects. Neither Allegiance nor any trade or business (whether or not incorporated) which is or has ever been under common control, or which is or has ever been treated as a single employer, with Allegiance under Section 414(b), (c), (m) or (o) of the Code (“ERISA Affiliate”) have at any time within the last six years, maintained, contributed to, or had any obligation to contribute to, or has any liability (fixed or contingent) with respect to, any “single-employer plan” as defined in Section 4001(a)(15) of ERISA or any plan subject to Sections 4063 or 4064 of ERISA (“multiple employer plan”).

(b) Each Employee Benefit Plan intended to be qualified under Section 401(a) of the Code, and the trust (if any) forming a part thereof, is qualified and tax exempt under Code Section 401(a) and 501(a) and has received a favorable determination letter from the IRS as to its qualification under the Code and to the effect that each such trust is exempt from taxation under Section 501(a) of the Code, which determination letter covers the GUST Amendments and to the Knowledge of Sellers, nothing has occurred since the date of such determination letter that could reasonably be expected to adversely affect such qualification or tax-exempt status.

(c) Allegiance does not provide nor is it obligated to provide, any life insurance or health benefits, including prescription drugs (whether or not insured) to any individual after his or her termination of employment or service with any of the Sellers or the Operating Subsidiaries, except as may be required under COBRA and at the expense of the individual or the individual’s beneficiary and except as provided under severance agreements.

To the Sellers’ Knowledge, no Multiemployer Plan is in “reorganization” or “insolvent.”

	(e) There are no collective bargaining agreements with any labor union representing Employees.

To Sellers’ Knowledge: (i) no collective bargaining agreement is currently being negotiated and (ii) no organizing effort is currently being made or has been threatened with respect to the Employees. Allegiance is and has been in material compliance with all Laws relating to employment practices, terms and conditions of employment (including termination of employment), wages, hours of work and occupational safety and health, and worker classification and at all times since November 23, 1999, has been in material compliance with the requirements of the Immigration Reform Control Act of 1986. Allegiance is in compliance with WARN and any similar state or local “mass layoff” or “plant closing” Law in all material respects. There is no unfair labor practice complaint pending or, to Sellers’ Knowledge, threatened against Allegiance before the National Labor Relations Board.


	(f) There is no Assumed Contract covering any person that, individually or collectively, could give rise to the payment of any amount that would constitute an “excess parachute payment” within the meaning the Section 280G of the Internal Revenue Code or any similar provision of foreign, state or local Law.

4.24 Litigation. Except as set forth on Schedule 4.24 of the Disclosure Schedules and for Claims that will be discharged pursuant to the Bankruptcy Court Order:

(e) At the Closing, Sellers shall reject in the Cases all Executory Contracts that do not constitute Assumed Contracts other than any such Executory Contracts (A) relating to the Excluded Assets or (B) assigned to any other Person. At Buyer’s written request, Sellers shall delay the effective date of the rejection of any Executory Contract designated by Buyer; provided that, for any such delay in the effective date, Buyer shall be responsible for all expenses directly or indirectly arising due to such delay in effective date on or after the Closing Date. Provided, further, that if Buyer requests a delay in rejection of an Executory Contract that results in rejection beyond the Closing Date, then Sellers shall retain such Executory Contract and it shall be treated as a Non-Transferred Asset and subject to (i) Sections 2.5 and 6.2 hereof, and (ii) the Operating Agreement.

The Committee shall establish working groups to discuss the following specific aspects of the transactions contemplated hereby: (i) human resources, (ii) network, (iii) operations, (iv) sales and marketing, (v) finance and (vi) information technology and shall agree as promptly as possible as to actions that will be taken to more efficiently operate the Business prior to Closing; provided that no such actions implemented prior to Closing shall have, or be reasonably expected to have, a detrimental impact on the ability of Allegiance to conduct the auction in a manner customary in similar proceedings, and further provided that all such actions shall be conducted in full compliance with the relevant Antitrust Laws. All reasonable costs associated with the establishment and the operation of the Committee shall be borne by Buyer.

Those Employees who accept Buyer’s offer of employment effective as of the Closing Date are referred to as the “Transferred Employees.” Following the Closing, Buyer shall provide any Employee who does not receive an offer of employment from the Buyer and any Employee who receives an offer of employment which does not provide for the terms of employment described in Section 6.8 (d) with severance benefits in accordance with Allegiance’s severance policies and past practice, provided, however, any Transferred Employee shall not be eligible to receive severance benefits pursuant to this Agreement.


	(c) Pursuant to the “Alternative Procedure” provided in section 5 of Revenue Procedure 96-60, 1996-2 C.B. 399, (i) Buyer and Sellers shall report on a predecessor/successor basis as set forth therein, (ii) Sellers will be relieved from filing a Form W-2 with respect to the Transferred Employees and (iii) Buyer will undertake to file (or cause to be filed) a Form W-2 for each such Transferred Employee for the year that includes the Closing Date (including the portion of such year that such Employee was employed by Allegiance). Sellers will provide Buyer on a timely basis with all payroll and employment-related information with respect to each such Employee.

	(d)

(i) Buyer shall grant each Transferred Employee service credit with Sellers (based on the employment commencement date set forth in the Employee Schedule), for purposes of eligibility and participation in the benefit plans, programs and arrangements (including the vacation and the severance policies), of Buyer, excluding service credit for benefit accruals under the defined benefit pension plan and eligibility for the retiree medical plan.

(ii) Unless otherwise required by any collective bargaining agreement to which any of Buyer’s employees are subject to as of the Closing Date, with

respect to Transferred Employees who will be subject to such collective bargaining agreement after the Closing, effective on the Closing Date, Buyer shall provide the Transferred Employees with (i) a salary or regular wage rate and bonus opportunity (if applicable) which is substantially the same in the aggregate as the salary or wage rate received or bonus opportunity available to such Transferred Employee immediately prior to the Closing, (ii) a job location no more than 75 miles from such Transferred Employee’s current job location and (iii) health, welfare and other employee benefits on the same basis as similarly situated employees of Buyer (or an Affiliate of Buyer), as determined by Buyer and in accordance with the terms of the plans governing such benefits.

(iii) As of the Closing Date, Buyer (or an Affiliate of Buyer) shall credit the Transferred Employees for all deductibles and out-of pocket expenses incurred by the Transferred Employees with respect to such benefits during the calendar year in which the Closing Date occurs and shall further waive (to the extent waived under Sellers’ employee benefit plans) all pre-existing conditions, exclusions and waiting periods under Buyer’s employee benefit plans for Transferred Employees.

(iv) Except as otherwise provided in this Agreement, Buyer shall not assume any Employee Benefit Plan or any liability or obligation thereunder, and, except as expressly provided in this Section 6.8, the terms of a Transferred Employee’s employment with Buyer (or an Affiliate) after the Closing shall be upon such terms and conditions as Buyer, in its sole discretion, shall determine.

(e) Sellers and any Operating Subsidiary shall cause the accounts of all Transferred Employees under any tax-qualified defined contribution plan maintained by Sellers or any Operating Subsidiary to become fully vested as of the Closing, and shall permit distribution of such accounts in accordance with the terms of any such plan. Notwithstanding the foregoing, Sellers or any Operating Subsidiary shall amend such defined contribution plan to permit the rollover of promissory notes evidencing outstanding participant loans of Transferred Employees, without default of such loan, to a tax-qualified defined contribution plan established by Buyer, and Buyer shall cause, as of a specified date within 90 days of Closing as determined by Buyer, such plan to accept such rollovers, provided that Allegiance has provided the Buyer evidence satisfactory to the Buyer of the qualified status of the Allegiance’s Internal Revenue Code Section 401(k) arrangement under Internal Revenue Code Section 401(a). Buyer shall take all action necessary and appropriate to ensure that, as of the Closing, Buyer maintains a tax-qualified defined contribution plan.


	(f) Allegiance shall cause, and Buyer agrees to assume, the health care and dependent care flexible spending accounts (and any corresponding assets and liabilities thereto) maintained with respect to Transferred Employees under any cafeteria plan maintained by Allegiance to be transferred to Buyer’s flexible benefits plan in accordance with IRS Revenue Ruling 2002-32.


	(g) Allegiance shall not, at any time between the date hereof and the Early Funding Date, or at any time prior to 60 days after the Early Funding Date,

effectuate a “plant closing” or “mass layoff,” as those terms are defined in the WARN Act, affecting in whole or in part any site of employment, facility, operating unit or Employee, without complying with the notice requirements and other provisions of the WARN Act except to the extent arising from Buyer’s actions, in which case Buyer shall be responsible for any Liabilities related thereto. In order to protect all parties, to the extent required by the WARN Act, Sellers agree to give notice in compliance with the WARN Act in a form satisfactory to Buyer, to all Employees required under the WARN Act to receive such notice not less than sixty (60) days and no more than ninety (90) days prior to the anticipated Closing Date, and shall repeat such notice, if necessary, due to any delay of Closing; provided, however, to the extent any Seller is unable to provide notice in compliance with the WARN Act due to any act, omission or direction of Buyer, Buyer shall be responsible for any Liabilities related thereto.

(h) Except where prohibited by law, Sellers shall provide promptly to Buyer, at Buyer’s request, any information or copies of personnel records (including addresses, dates of birth, dates of hire and dependent information) relating to the Transferred Employees or relating to the service of Transferred Employees with Sellers prior to the Closing. Sellers and Buyer shall each cooperate with the other and shall provide to the other such documentation, information and assistance as is reasonably necessary to effect the provisions of this Section 6.8(h).

(i) As part of the Transition Plan, certain Employees of Sellers will be retained by Sellers as of the Closing. Those Employees may or may not be Transferred Employees as referenced in this Section 6.8. The parties will cooperate in developing the Transition Plan such that, to the extent permitted by law, such Employees are subject to the same terms and conditions as they would have been if they had not been retained by Sellers at Closing, and instead had become Transferred Employees or been terminated, as the case may be, at Closing. For purposes of Sections 6.8(a), (b), (c), (d), (e), (f) and (h) in the case of an Employee who remains with the Sellers subsequent to the Closing Date for the purposes of continuing to conduct the Business with respect to the Non-Transferred Assets and who receives and accepts an offer of employment from the Buyer post-Closing, references to the “Closing Date” shall be replaced with the date of hire by the Buyer, or as otherwise specified in the Operating Agreement.

6.9 Further Agreements. Sellers authorize and empower Buyer after the Closing Date to receive and to open all mail received by Buyer relating to the Acquired Assets, the Business or the Assumed Liabilities and to deal with the contents of such communications in any proper manner. Sellers shall (a) promptly deliver to Buyer, any mail or other communication received by them after the Closing Date, (b) promptly wire transfer in immediately available funds to Buyer, any cash, electronic credit or deposit received by Sellers and (c) promptly forward to Buyer, any checks or other instruments of payment that it received, in each case relating to the Acquired Assets, the Business or the Assumed Liabilities. Buyer shall (a) promptly deliver to Sellers, any mail or other communication received by it after the Closing Date, (b) promptly wire transfer in immediately available funds to ATI, any cash, electronic credit or deposit received by Buyer and (c) promptly forward to ATI, any checks or other instruments of payment that

it receives, in each case relating to the Excluded Assets or any Excluded Liabilities. From and after the Closing Date, Sellers shall refer all inquiries with respect to the Business, the Acquired Assets and the Assumed Liabilities to Buyer, and Buyer shall refer all inquiries with respect to the Excluded Assets and the Excluded Liabilities to Sellers.

6.10 Payment of Transfer Taxes and Tax Filings.

(a) Fifty percent (50%) of all Transfer Taxes arising out of the transfer of the Acquired Assets and any Transfer Taxes required to effect any recording or filing with respect thereto shall be paid by each of Buyer on the one hand and Sellers on the other hand. The parties shall use commercially reasonable efforts to have included in the Sale Order and Confirmation Order a provision that provides that the transfer of the Acquired Assets shall be free and clear of any stamp or similar taxes under section 1146(c) of the Bankruptcy Code. At least twenty (20) Business Days prior to Closing, Sellers shall submit to Buyer a list of all Transfer Taxes (by tax name, tax jurisdiction and general description of the Acquired Assets subject to such tax) that it anticipates collecting from Buyer at Closing. Buyer may submit to Sellers evidence that it believes such Transfer Tax should not be applicable. Sellers shall review such evidence in a timely and good faith manner and respond to Buyer prior to Closing. Sellers and Buyer shall cooperate to timely prepare and file any returns or other filings relating to such Transfer Taxes, including any claim for exemption or exclusion from the application or imposition of any Transfer Taxes.

(b) Each party shall furnish or cause to be furnished to the others, upon request, as promptly as practicable, such information and assistance relating to the Acquired Assets and the Business as is reasonably necessary for filing of all Tax Returns, including any claim for exemption or exclusion from the application or imposition of any Taxes or making of any election related to Taxes, the preparation for any audit by any taxing authority and the prosecution or defense of any claim, suit or proceeding relating to any Tax Return.


	(c) Sellers acknowledge and agree that Buyer shall have an administrative expense claim with respect to Sellers’ share of any Transfer Taxes arising out of the transfer of the Acquired Assets under this Section 6.10 that have not been paid when due.

6.11 Filing of Tax Returns.

Sellers shall prepare and file, or cause to be prepared and filed, all Tax Returns for or on behalf of Sellers and any Affiliated Group that are required to be filed for periods that include or end on or prior to the Closing Date. Subject to Section 2.3(c), Sellers shall pay, or shall cause to be paid, all Taxes due and payable by Sellers with respect to periods that include or end on or prior to the Closing Date when due.

6.12 Proration of Taxes and Certain Charges. Except as provided in Section 6.10, all real property Taxes, personal property Taxes or similar ad valorem obligations levied with respect to the Acquired Assets for any taxable period that includes the day before the Early Funding Date and ends after the Early Funding Date, whether imposed or assessed before or after the Early Funding Date, shall be prorated between Sellers and Buyer as of 12:01 A.M. on the Early Funding Date. If any Taxes subject to proration are paid by Buyer, on the one hand, or Sellers, on the other hand, the proportionate amount of such Taxes paid (or in the event a refund of any portion of such Taxes previously paid is received, such refund) shall be paid promptly by (or to) the other after the payment of such Taxes (or promptly following the receipt of any such refund). Notwithstanding the foregoing proration, any interest, penalties or additions to Tax relating to a Tax that is subject to proration shall be borne by the party whose actions or omissions gave rise to such item, and shall be reimbursed (and any refund remitted) consistent with the preceding sentence.

6.13 Best Efforts.

(a) Subject to the terms and conditions of this Agreement, each of the parties hereto shall use its respective 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 hereto in doing, all things necessary, proper or advisable under applicable Laws and regulations to ensure that the conditions set forth in this Agreement are satisfied and to consummate and make effective, in the most expeditious manner practicable, the transactions contemplated by this Agreement, including prosecuting confirmation of the Bankruptcy Plan notwithstanding the objection of any party in interest. Subject to the terms and conditions of this Agreement, the parties shall not take any action or refrain from taking any action, the effect of which would be to delay or impede the ability of Allegiance and Buyer to consummate the transactions contemplated by this Agreement, unless in such party’s reasonable judgment, taking such action or refraining from action is consistent with achieving the ultimate objective of consummating the transactions contemplated hereby.


	(b) Without limiting the generality of the foregoing, the parties hereto shall furnish to each other such necessary information and reasonable assistance, as each may request in connection with preparation and filing of applications and motion papers, including the Sale Motion needed to obtain Bankruptcy Court approval of the transactions contemplated by this Agreement.

6.14 HSR Act and General Governmental Consents.

(a) Subject to the terms and conditions of this Agreement, each of the parties hereto shall use its respective best efforts to (1) obtain from any Governmental Entity, any consents, licenses, permits, waivers, approvals, authorizations or orders required to be obtained or made by Sellers or Buyer or any of their respective Subsidiaries, or to avoid any action or proceeding by any Governmental Entity (including those in connection with the HSR Act), in connection with the authorization, execution and delivery of this Agreement and the consummation of the transactions

contemplated herein, (2) subject to any restrictions under Antitrust Laws (as defined herein), to the extent practicable, (A) promptly notify each other of any communication to that party from any Governmental Entity with respect to this Agreement and the transactions contemplated hereby, (B) permit a Representative of the other party reasonably acceptable to the first party to attend and participate in meetings (telephonic or otherwise) with any Governmental Entity and (C) permit the other party to review in advance, as reasonable, any proposed written communication to any Governmental Entity, and (3) make all necessary filings (including, to the extent applicable, appropriate filing of a notification and report form pursuant to the HSR Act on or prior to the date that is five (5) Business Days after the date of execution of this Agreement), and thereafter make any other required submissions, with respect to this Agreement and the transactions contemplated hereby under any applicable Law. Sellers and Buyer shall cooperate with each other in connection with the making of all such filings, including (i) providing all information required or appropriate for any application or other filing and (ii) as reasonably practicable, providing copies of all such documents to the other party and its advisors prior to filing and, if requested, accepting all reasonable additions, deletions or changes suggested in connection therewith.

(b) In furtherance and not in limitation of the foregoing, the parties shall use their best efforts to resolve such objections, if any, as may be asserted with respect to the transactions contemplated by this Agreement under any antitrust, competition or trade regulatory Laws of any Governmental Entity (“Antitrust Laws”). The parties agree to take any action (including agreeing to hold separate or to divest any of the Acquired Assets (a “Designated Change”) that may be required by or would otherwise resolve any objections made by (1) the applicable Governmental Entity (including the Antitrust Division of the United States Department of Justice or the Federal Trade Commission) in order to resolve any objections as such Governmental Entity or authority may have to such transactions under such Antitrust Law, or (2) by any domestic or foreign court or similar tribunal, in any suit brought by a private party or Governmental Entity challenging the transactions contemplated by this Agreement as violative of any Antitrust Law, in order to (i) avoid material delay in the closing of such transactions or (ii) avoid the entry of, or to effect the dissolution of, any injunction, temporary restraining order or other order that has the effect of preventing the consummation of any of such transactions. The entry by a court, in any suit brought by a private party or Governmental Entity challenging the transactions contemplated by this Agreement as violative of any Antitrust Law, of an order or decree permitting the transactions contemplated by this Agreement, but requiring a Designated Change, or that would otherwise limit the Buyer’s freedom of action with respect to, or its ability to retain, the Acquired Assets, shall not be deemed a failure to satisfy the conditions specified in Section 7.1(a) or Section 7.1(c) hereof. Notwithstanding any other provision of this Agreement, nothing herein shall require Buyer or any of its Affiliates to hold separate or to divest any of the businesses, product lines or assets of Buyer or its Affiliates.

6.18 Disclosure Supplements. Prior to the Early Funding Date, Sellers shall deliver updated Disclosure Schedules hereto with respect to any matter hereafter arising or any information obtained after the date hereof which, if existing, occurring or known at or prior to the date of this Agreement, would have been required to be set forth or

connection with the FCC applications and the State PUC applications, including furnishing to the FCC and the State PUCs any documents, materials, or other information requested by the FCC and the State PUCs in order to obtain the FCC Consent and the State PUC Consents as expeditiously as practicable.

ARTICLE VIII
TERMINATION

8.1 Termination of Agreement. This Agreement may be terminated and the transactions contemplated hereby abandoned at any time prior to the Closing:


	(a) By mutual written consent of Buyer and ATI;

(b) By Buyer or ATI if neither the Early Funding Date nor the Closing Date shall have occurred on or before August 18, 2004; provided, however, that if neither the Early Funding Date nor the Closing shall have occurred on or before such date due to a breach of this Agreement by Buyer or any Seller, Buyer or ATI (if a Seller is the breaching party), as the case may be, may not terminate this Agreement pursuant to this Section 8.1(b);


	(c) By Buyer, immediately if any of the following shall have occurred:

(i) Any Seller (A) agrees in writing, (B) publicly announces its intention (including by selecting a competing bidder at the Bankruptcy Court’s auction relating to the transactions contemplated hereby), or (C) is authorized by its board of directors to proceed with a Competing Transaction, irrespective of whether such Competing Transaction is approved by the Bankruptcy Court and/or consummated;

(ii) Prior to the Closing, any Seller abandons or files a motion with the Bankruptcy Court to abandon all or any material portion of the Acquired Assets;

(iii) Prior to the Closing, any Seller files any plan of reorganization other than the Bankruptcy Plan, files any material amendment to the Bankruptcy Plan, withdraws the Bankruptcy Plan or consents to the reduction of the Exclusivity Period or fails timely to file motions to obtain orders of the Bankruptcy Court extending the Exclusivity Period or the Bankruptcy Court denies confirmation of the Bankruptcy Plan; provided, however, that to the extent either Sellers or Buyer has delivered an Early Closing Election, this Section 8.1(c)(iii) shall be inapplicable;

(iv) The Bankruptcy Court terminates the Exclusivity Period or declines to extend the Exclusivity Period; provided, however, that to the extent either Sellers or Buyer shall have delivered an Early Closing Election, this Section 8.1(c)(iv) shall be inapplicable;

(v) The voluntary dismissal or conversion of any of the Cases to a case under chapter 7 of the Bankruptcy Code; or

(vi) Upon the appointment in the Cases of a trustee or examiner with managerial powers under section 1104 of the Bankruptcy Code; or

(vii) Prior to the Early Funding Date, any Order is entered by the Bankruptcy Court which would result in the failure of any of the conditions to the obligations of Buyer set forth in Section 7.1 or 7.2; provided, that following the Early Funding Date, this Section 8.1(c) shall have no further force or effect.


	(d) By Sellers, on the one hand, or Buyer, on the other, if Buyer or Sellers, as the case may be, materially breach any of its covenants under this Agreement, unless such breach shall be cured within ten (10) Business Days after such other party shall have received notice of such breach in accordance with the terms hereof.

(e) Prior to the Early Funding Date, by Buyer if there is a breach of any representation or warranty contained in Article IV hereof (without regard to any qualifications concerning materiality or Material Adverse Effect contained in Article IV), which breach, in the aggregate with all other such breaches, if any, would give rise to a failure of the condition set forth in Section 7.2(a) (with the date of such termination being substituted for the references to Early Funding Date therein) and which breach could not reasonably be expected to be cured using reasonable efforts by the date set forth in Section 8.1(b); provided, that following the Early Funding Date, this Section 8.1(e) shall have no further force or effect.

8.2 Effect of Termination. In the event of termination of this Agreement pursuant to this Article VIII, written notice thereof shall be given to the other party of this Agreement as promptly as practicable and this Agreement shall terminate and the transactions contemplated hereby shall be abandoned, without further action by Buyer or Sellers. If this Agreement is terminated as provided herein there shall be no liability or

obligation on the part of Sellers or Buyer, unless (i) this Agreement is terminated (A) by Buyer pursuant to Section 8.1(b) when ATI does not have the right to terminate this Agreement pursuant to Section 8.1(b) due to breach of the Agreement by Sellers, or (B) by Buyer pursuant to Section 8.1(c) or (d); or (ii) Buyer terminates this Agreement pursuant to Section 8.1(e) as a result of Sellers’ gross negligence or willful, wanton or reckless action or inaction taken or not taken with an intent to cause the termination of this Agreement or otherwise negatively impact the transactions contemplated hereby (collectively, a “Sellers’ Intentional Breach”) or Buyer elects not to close because the condition set forth in Section 7.2(a) has not been satisfied as a result of a Sellers’ Intentional Breach; provided, however, that with respect to any such termination of this Agreement pursuant to Section 8.1(b), (c) or (d) following the Sale Order Approval Date, or (ii) Buyer’s election to terminate this Agreement pursuant to Section 8.1(c) or not to close, in each case because the condition set forth in Section 7.2(a) has not been satisfied, as a result of a Sellers’ Intentional Breach following the Sale Order Approval Date, Buyer shall be entitled to terminate this Agreement immediate payment, as liquidated damages and not as a penalty, of (i) the Expense Reimbursement (which Expense Reimbursement shall not exceed $10 million) and (ii) $30 million (the (“Liquidated Damages”). Sellers and Buyer acknowledge that the damage suffered by the Buyer in the event of any such termination would be impossible to calculate, and the Liquidated Damages constitutes a reasonable estimate of such damages. In the event prior to the Early Funding Date Buyer terminates this Agreement pursuant to Section 8.1(e) or elects not to close, in each case because the condition set forth in Section 7.2(a) has not been satisfied as a result of some reason other than a Sellers’ Intentional Breach, Buyer shall be entitled to immediate payment of the Expense Reimbursement (which Expense Reimbursement shall not exceed $5 million). Except as provided in Section 9.14, Buyer’s sole and exclusive remedy under this Agreement shall be limited to the recovery of the amounts set forth in this Section 8.2. None of the amounts payable under this Section 8.2 or 8.3 shall prime the Liens held by the Sellers’ senior secured lenders and any such amounts payable shall be subordinate to the carve out for professional fees and fees under 28 U.S.C. § 1930 as provided in the Bankruptcy Court’s order authorizing Sellers to use cash collateral that was entered in the Cases.

8.3 Bankruptcy Events.


	(a) At anytime prior to Closing, Sellers in their sole discretion, after consultation with the statutory committee of unsecured creditors appointed in the Chapter 11 Cases and the Sellers’ pre-Petition senior lenders, may deliver an Early Closing Election to Buyer.


	(b) In the event that Sellers fail to comply with the timeline set forth on Exhibit J, or at anytime from and after June 30, 2004 and prior to Closing, Buyer may deliver an Early Closing Election to Sellers.


	(c) In the event an Early Closing Election is delivered pursuant to the terms hereof, the provisions of Section 3.5 hereof shall apply; provided, however, that Sellers shall serve, at least twenty (20) days prior to the Closing, the notice of Sellers’ intent to assume and assign the Assumed Contracts on all non-debtor parties to the

Assumed Contracts, rather than at least twenty (20) days prior to the hearing to confirm the Bankruptcy Plan. Within three (3) Business Days of receipt by Sellers or Buyer, as applicable, of an Early Closing Election notice, Buyer will provide to Sellers a list of Executory Contracts to be assumed by Allegiance and in the case of Sellers, assigned to Buyer (the “Additional Assumed Contracts”) and Sellers shall immediately notify the counterparties to such Additional Assumed Contracts substantially in the form of notice attached to the Sale Order. Except as provided above, the Closing following an Early Closing Election shall occur no sooner than twenty (20) Business Days after the delivery of such notice. For the avoidance of doubt, to the extent the Early Closing Election is exercised, Section 7.4(a) shall have no further force and effect. For the purposes of this Agreement “Early Closing Election” shall mean the delivery by Sellers to Buyer or by Buyer to Sellers, as applicable, of a written irrevocable election to close the transactions contemplated by this Agreement pursuant to an asset sale rather than a sale of stock of the direct Subsidiaries of ATCW. To the extent an Early Closing Election is delivered, the Operating Subsidiaries shall be deemed to constitute Sellers under this Agreement and each Operating Subsidiary shall sell its assets to Buyer. Notwithstanding anything to the contrary contained herein, the Bankruptcy Plan shall provide that Buyer is not assuming liabilities of the Operating Subsidiaries of the types and in the nature of those listed in Section 2.4 in connection with Buyer’s acquisition of the stock of the Operating Subsidiaries in accordance with the terms and conditions hereof.

ARTICLE IX
MISCELLANEOUS

9.1 Expenses. Except as set forth in this Agreement (e.g., Liquidated Damages provisions and the expense sharing arrangements set forth in Sections 2.6, 2.7 and 6.10) and whether or not the transactions contemplated hereby are consummated, each party shall bear its own costs and expenses incurred or to be incurred by such party in connection with this Agreement and the consummation of the transactions contemplated hereby.

9.2 Assignment. Neither this Agreement nor any of the rights or obligations hereunder may be assigned by Sellers without the prior written consent of Buyer, or by Buyer without the prior written consent of ATI; provided, however, that, Buyer may assign its rights and obligations hereunder, in whole or in part, to any wholly-owned Subsidiary of Buyer, provided that no such assignment shall relieve Buyer of its liabilities and obligations hereunder if such assignee does not perform such obligations and provided, further that this Agreement may be assigned to one or more trustees appointed by the Bankruptcy Court to succeed to the rights of Sellers. Subject to the foregoing, this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns, and except as otherwise expressly provided herein, no other Person shall have any right, benefit or obligation hereunder.

9.3 Parties in Interest. This Agreement shall be binding upon and inure solely to the benefit of Sellers and Buyer, and nothing in this Agreement, express or implied, is intended to or shall confer upon any other person any rights, benefits or remedies of any

nature whatsoever under or by reason of this Agreement. Without limiting the foregoing, no direct or indirect holder of any equity interests or securities of either Sellers (other than Sellers themselves) or Buyer (whether such holder is a limited or general partner, member, stockholder or otherwise), nor any Affiliate of either Sellers or Buyer, nor any Representative or other controlling person of each of the parties hereto and their respective Affiliates shall have any liability or obligation arising under this Agreement or the transactions contemplated thereby.

9.4 Notices. Unless otherwise provided herein, any notice, request, instruction or other document to be given hereunder by any party to any other party shall be in writing and shall be delivered in person or by courier or facsimile transmission (with such facsimile transmission confirmed by sending a copy of such notice, request, instruction or other document by certified mail, return receipt requested, or overnight mail) or mailed by certified mail, postage prepaid, return receipt requested (such mailed notice to be effective on the date such receipt is acknowledged), as follows:

or to such other place and with such other copies as either party may designate as to itself by written notice to the other party. Notices sent as provided herein shall be deemed given on the date received by the recipient. If a recipient rejects or refuses to accept a notice given pursuant to this Section, or if a notice is not deliverable because of a changed address or fax number of which no notice was given in accordance with the provisions hereof, such notice shall be deemed to be received two (2) days after such notice was mailed (whether as the actual notice or as the confirmation of a faxed notice) in accordance with the terms hereof.

9.5 Choice of Law. This Agreement shall be construed and interpreted, and the rights of the parties shall be determined, in accordance with the Bankruptcy Code and the substantive laws of the State of New York for contracts expected and likely to be performed solely within such state without regard to the conflict of laws principles thereof or of any other jurisdiction.

9.6 Entire Agreement; Amendments and Waivers. This Agreement (including the schedules and exhibits hereto) and the other Transaction Documents constitute the entire agreement between the parties pertaining to the subject matter hereof and supersede all prior agreements, understandings, negotiations, and discussions, whether oral or written, of the parties. No supplement, modification or waiver of this Agreement (including any schedule hereto) shall be binding unless the same is executed in writing by all parties. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provision hereof (whether or not similar), and no such waiver shall constitute a continuing waiver unless otherwise expressly provided.

9.7 No Recourse Against Third Parties. Buyer agrees for itself and for all of its officers, directors, shareholders, Affiliates, attorneys, agents and any other parties making any claim by, through or under the rights of such persons (collectively, the “Buyer Group”) that no member of the Buyer Group shall have any rights against any creditor, officer, director, shareholder (other than Sellers themselves), Affiliate, attorney or agent of Allegiance (each, individually, a “Non-Recourse Person”) for any damages, suits, claims, proceedings, fines, judgments, costs or expenses (including attorneys’ fees and incidental, consequential or punitive damages) (collectively, “Losses”) that any Buyer Party may suffer in connection with this Agreement. If any member of the Buyer Group makes a claim against any person or entity other than Buyer that is not a Non-Recourse Person (a “Third Person”) that in any way gives rise to a claim by such Third Party against any Non-Recourse Person asserting that such Non-Recourse Person is or may be liable to such Third Party with respect to any Losses arising in connection with this Agreement (whether by way of indemnification, contribution, or otherwise on any theory whatever) (a “Claim Over”), such member of the Buyer Group shall reduce or

credit against any judgment or settlement such member of the Buyer Group may obtain against such Third Party the full amount of any judgment or settlement such Third Party may obtain against the Non-Recourse Person on such Claim Over, and shall, as part of any settlement with such Third Party, obtain from such Third Party for the benefit of such Non-Recourse Person a satisfaction in full of such Third Party’s Claim Over against the Non-Recourse Person. The provisions of this Section 9.7, however, shall not apply as to any fraud claims.

9.8 Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. Delivery of an executed counterpart of a signature page to this Agreement by telecopy shall be as effective as delivery of a manually executed counterpart of this Agreement. In proving this Agreement, it shall not be necessary to produce or account for more than one such counterpart signed by the party against whom enforcement is sought.

9.9 Confidentiality. Prior to the Closing and after any termination of this Agreement, the provisions of the Confidentiality Agreement shall continue in full force and effect; provided, however, that effective as of the date hereof the provisions of the Confidentiality Agreement restricting Buyer and its Affiliates from discussing the transaction contemplated by this Agreement with third parties shall no longer apply. After the Closing, Buyer shall no longer be subject to the provisions of the Confidentiality Agreement, except to the extent the confidential information specifically relates to Shared Technologies. In the event of any conflict between the provisions of this Agreement and the Confidentiality Agreement, the provisions of this Agreement shall prevail. From and after the Closing, Sellers agree to keep confidential all confidential information relating to the Business, and agree not to disclose such information except as required by Law. Notwithstanding anything herein to the contrary, Buyer and Sellers (and each Affiliate and person acting on behalf of any such party) agree that each party (and each Representative of such party) may disclose to any and all persons, without limitation of any kind, the tax treatment and tax structure of the transaction and all materials of any kind (including opinions or other tax analyses) that are provided to such party or such person relating to such tax treatment and tax structure, except to the extent necessary to comply with any applicable federal or state securities laws. This authorization is not intended to permit disclosure of any other information, including (i) any portion of any materials to the extent not related to the tax treatment or tax structure of the transaction, (ii) the identities of participants or potential participants in the transaction, (iii) the existence or status of any negotiations, (iv) any pricing or financial information (except to the extent such pricing or financial information is related to the tax treatment or tax structure of the transaction) or (v) any other term or detail not relevant to the tax treatment or the tax structure of the transaction.

9.10 Invalidity. If anyone or more of the provisions contained in this Agreement (other than any of the provisions contained in Article II or Article III hereof) or in any other instrument referred to herein, shall, for any reason, be held to be invalid, illegal or unenforceable in any respect, the parties shall use their best efforts, including

the amendment of this Agreement, to ensure that this Agreement shall reflect as closely as practicable the intent of the parties hereto on the date hereof.

9.11 Headings. The table of contents and the headings of the Articles and Sections herein are inserted for convenience of reference only and are not intended to be a part of, or to affect the meaning or interpretation of, this Agreement.

9.12 Exclusive Jurisdiction. Without limiting any party’s right to appeal any order of the Bankruptcy Court, (a) the Bankruptcy Court shall retain exclusive jurisdiction to enforce the terms of this Agreement and to decide any claims or disputes which may arise or result from, or be connected with, this Agreement, any breach or default hereunder, or the transactions contemplated hereby, and (b) any and all claims, actions, causes of action, suits and proceedings related to the foregoing shall be filed and maintained only in the Bankruptcy Court, and the parties hereby consent to and submit to the jurisdiction and venue of the Bankruptcy Court and shall receive notices at such locations as indicated in Section 9.4 hereof.

9.13 Waiver of Right to Trial by Jury. Each party to this Agreement waives any right to trial by jury in any action, matter or proceeding regarding this Agreement or any provision hereof.

9.14 Specific Performance. Each of the parties hereto acknowledges that the other party hereto would be irreparably damaged in the event any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. Accordingly, each of the parties hereto shall be entitled to an injunction or injunctions to prevent breaches of the provisions of this Agreement and to enforce specifically this Agreement and the terms and provisions thereof in any action instituted in any court of the United States or any state thereof having subject matter jurisdiction, in addition to any other remedy to which the parties may be entitled, at law, in equity or pursuant to this Agreement.

9.15 Counting. If the due date for any action to be taken under this Agreement (including the delivery of notices) is not a Business Day, then such action shall be considered timely taken if performed on or prior to the next Business Day following such due date.

9.16 Service of Process. Each party irrevocably consents to the service of process in any action or proceeding by receipt of mailed copies thereof by national courier service or registered United States mail, postage prepaid, return receipt requested, to its address as specified in or pursuant to Section 9.4 hereof. However, the foregoing shall not limit the right of a party to effect service of process on the other party by any other legally available method.

9.17 Time of Essence; Effectiveness of the Closing Date. With regard to all dates and time periods set forth or referred to in this Agreement, time is of the essence. In the event the Closing Date occurs prior to the occurrence of the Early Funding Date,

for purposes of Article II, Sections 6.1, 7.1, 7.2, 7.3, and 8.1, all references to Early Funding Date shall be replaced with references to the Closing Date.

9.18 Exhibits and Schedules. The Exhibits and Schedules attached to, delivered with and identified to this Agreement are a part of this Agreement the same as if fully set forth herein and all references herein to any Section of this Agreement shall be deemed to include a reference to any Schedule named therein. Any disclosure made in any Schedule to this Agreement which is applicable to another Schedule to this Agreement shall be deemed to be made with respect to such other Schedule regardless of whether or not a specific cross reference is made thereto if the relevance of such disclosure to such other schedule is reasonably apparent on its face.

9.19 Interpretation.


	(a) Whenever the words “include,” “includes” or “including” are used in this Agreement they shall be deemed to be followed by the words “without limitation.”


	(b) The words “hereof,” “herein” and “hereunder” and words of similar import when used in this Agreement shall refer to this Agreement as a whole and not to any particular provision of this Agreement, and Section, Schedule and Exhibit references are to this Agreement unless otherwise specified.


	(c) The meanings given to terms defined herein shall be equally applicable to both singular and plural forms of such terms.


	(d) Words denoting any gender shall include all genders. Where a word or phrase is defined herein, each of its other grammatical forms shall have a corresponding meaning.


	(e) A reference to any party to this Agreement or any other agreement or document shall include such party’s successors and permitted assigns.

	(f) A reference to any legislation or to any provision of any legislation shall include any modification or re-enactment thereof, any legislative provision substituted therefor and all regulations and statutory instruments issued thereunder or pursuant thereto.


	(g) All references to “$” and “dollars” shall be deemed to refer to United States currency unless otherwise specifically provided.


	(h) All references to any financial or accounting terms shall be defined in accordance with GAAP.

9.20 Preparation of this Agreement. Buyer and Sellers hereby acknowledge that (i) Buyer and Sellers jointly and equally participated in the drafting of this Agreement and all other agreements contemplated hereby, (ii) Buyer and Sellers have been adequately represented and advised by legal counsel with respect to this Agreement

and the transactions contemplated hereby, and (iii) no presumption shall be made that any provision of this Agreement shall be construed against either party by reason of such role in the drafting of this Agreement and any other agreement contemplated hereby.
