Section 2.2 Purchase and Sale of Purchased Assets.

(a) Subject to the terms and conditions of this Agreement, Seller shall sell, assign, convey, transfer and deliver (or cause to be sold, assigned, conveyed, transferred and delivered) to Buyer as of the Closing Date, and Buyer shall purchase and take assignment and

CLOSING

Section 3.1 Closing. Subject to the Parties’ satisfaction or waiver of the conditions precedent set forth in Article VII, the closing and consummation of the transactions contemplated by this Agreement (the “Closing”) shall take place on January 9, 2004 at 10:00 a.m., Eastern Time, at the offices of ▇▇▇▇▇▇▇▇ & ▇▇▇▇▇ LLP at ▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇, ▇▇, ▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇, ▇▇ ▇▇▇▇▇ and at such other places as the Parties may agree, or, if the conditions set forth in Article VII have not been satisfied or waived as of such date, on such later date that is mutually agreed between Seller and Buyer (such date being the “Closing Date”).

Section 3.2 Purchase Price; Adjustment Amount.

(a) Subject to the terms and conditions set forth in this Agreement, in addition to the assumption by Buyer of the Assumed Liabilities, Buyer and Parent agree to pay at Closing to Seller in consideration for the Purchased Shares and the Purchased Assets an aggregate purchase price equal to $19,000,000 (as adjusted based on the Closing Net Working Capital Statement pursuant to Section 3.2(d), the “Purchase Price”), which shall be paid in cash, in immediately available funds by wire transfer to an account designated by Seller by written notice to Parent at least two Business Days prior to the Closing Date (the “Consideration”).

(b) (i) If Parent has complied with its obligations in Section 6.3(e) and has properly delivered to Seller the Substitute Financing Notice, Parent shall not be required thereafter to pay the Purchase Price in cash, and the Purchase price shall be payable as contemplated by this Section 3.2(b) (but only to the extent Seller agrees to accept the Substitute Financing). Simultaneously with delivery to Seller of the Substitute Financing Notice, Parent shall offer to Seller the option to accept as the Purchase Price, in lieu of cash consideration, the securities contemplated by the Private Financing (on the terms set forth in Exhibit I, or on terms that were more favorable to the provider of the Private Financing to the extent they were set forth in any Completed Financing Agreements), pro rated to reflect the difference between (A) the aggregate amount of the Private Financing and (B) the Purchase Price (the “Substitute Financing”). Parent shall hold such offer open, and such offer shall be irrevocable, for a period of thirty (30) days. Seller shall be entitled (but not obligated) to accept such offer by notifying

Parent of its acceptance at any time within such 30-day period, with such acceptance being conditioned upon the negotiation of definitive agreements that are acceptable in form and substance to Seller (and not inconsistent with the terms of Exhibit I) and Seller’s completion of, and satisfaction in all respects with, its due diligence investigation of the Buyer. Parent shall thereafter use its reasonable best efforts to negotiate with Seller and execute, as promptly as practicable, definitive agreements for the Substitute Financing; provided, that to the extent that Parent had previously entered into any definitive agreements for the Private Financing (the “Completed Financing Agreements”) but was for any reason unable to complete the Private Financing, Parent shall, if requested by Seller (at Seller’s sole and absolute discretion), enter into definitive agreements with Seller for the Substitute Financing having the same substantive terms as those contained in the Completed Financing Agreements. To facilitate the process of negotiating definitive documents, Parent shall promptly make available to Seller, after Seller notifies Parent of its interest in proceeding with the Substitute Financing, all Completed Financing Agreements or, if none, the most recent drafts of all definitive documents that Parent had been negotiating in connection with the Private Financing.

(ii) Parent shall reimburse Seller at the Closing for its reasonable attorneys’ fees and expenses incurred in the negotiation and preparation of definitive agreements for the Substitute Financing.

(iii) If Seller agrees to accept the Substitute Financing in lieu of cash consideration for the Purchase Price, then notwithstanding any other provision of this Agreement to the contrary, if Seller should become required to pay any amount to Parent pursuant to Section 3.2(d) in connection with the determination of Closing Net Working Capital, such amount shall be payable, at the sole option of Seller, in securities received in the Substitute Financing, rather than in cash, with such securities being valued on the basis they are valued in the definitive agreements for the Substitute Financing.

(c) Prior to the Closing Date, the Seller shall (i) prepare and deliver to Parent a statement (the “November 30 Net Working Capital Statement”) setting forth Net Working Capital (including the components thereof) as of November 30, 2003 (the “November 30 Closing Net Working Capital”), and (ii) provide Parent with a certificate of its Chief Financial Officer stating that the November 30 Net Working Capital Statement was prepared by Seller in good faith and in a manner consistent with Seller’s past practices, is consistent with the Books and Records and presents fairly the balance sheet items of the Business reflected thereon as of the date thereof in accordance with this Agreement (the “Net Working Capital Certificate”).

(d) As soon as practicable (and in any event within forty (40) days following the Closing), Seller shall prepare and deliver to Parent and its counsel the Audited Financial Statements, the Closing Balance Sheet, a statement (the “Closing Net Working Capital Statement”) setting forth Net Working Capital as of the close of business on the Closing Date (the “Closing Net Working Capital”) based on the Closing Balance Sheet, and all work papers and back-up materials relating thereto. The costs and expenses of preparing the Closing Balance Sheet and the Audited Financial Statements shall be borne 50% by Seller and 50% by Parent. Each of Parent and Buyer shall assist Seller and its Representatives in the preparation of the Closing Balance Sheet and shall provide Seller and its Representatives access at all reasonable times to the personnel, properties, Books and Records of the Business, including the Acquired

Aether Entities, for such purpose. No changes shall be made in any reserve or other account existing as of the date of the Closing Balance Sheet except as (i) a result of events occurring after the date of the Closing Balance Sheet and, in such event, only in a manner consistent with past practices and (ii) as required by GAAP. The Closing Balance Sheet and the Closing Net Working Capital Statement shall be conclusive and binding on the parties hereto unless Parent gives written notice of any objections thereto setting forth in reasonable detail the amounts in dispute and the basis for such disagreement (a “Purchase Price Objection Notice”) to Seller within thirty (30) days after its receipt of the Audited Financial Statements, Closing Balance Sheet, Closing Net Working Capital Statement and all work papers and back-up materials relating thereto. If Parent delivers a Purchase Price Objection Notice as provided above, the parties shall attempt in good faith to resolve such dispute, and any resolution by them as to any disputed amounts shall be final, binding and conclusive on the parties. If the parties are unable to resolve, despite good faith negotiations, all disputes reflected in the Purchase Price Objection Notice within thirty (30) days thereafter (the “Purchase Price Resolution Period”), then the parties will, within thirty (30) days after the expiration of the Purchase Price Resolution Period, submit any such unresolved dispute to an independent accounting firm mutually acceptable to Parent and Seller (the “Independent Accounting Firm”). Parent and Seller shall provide to the independent accounting firm all work papers and back-up materials relating to the unresolved disputes requested by the Independent Accounting Firm to the extent available to Parent or its Representatives or Seller or its Representatives. Parent and Seller shall be afforded the opportunity to present to the Independent Accounting Firm any material related to the unresolved disputes and to discuss the issues with the Independent Accounting Firm. The determination by the Independent Accounting Firm, as set forth in a notice to be delivered to Parent and Seller within thirty (30) days after the submission of the unresolved disputes to the Independent Accounting Firm, shall be final, binding and conclusive on the parties. The fees and expenses of the Independent Accounting Firm shall be borne by Parent and Seller in inverse proportion as they may prevail on matters resolved by the Independent Accounting Firm, which proportionate allocations shall also be determined by the Independent Accounting Firm at the time the determination of the Independent Accounting Firm is rendered on the merits of the matters submitted. The Closing Net Working Capital reflected in the Closing Net Working Capital Statement, as revised to reflect the resolution of any and all disputes by the parties and/or the Independent Accounting Firm, shall be deemed to be the Closing Net Working Capital. The “Adjustment Amount” (which may be a positive or negative number) shall equal the amount determined by subtracting $3,750,020 (the “Initial Net Working Capital”) from the Closing Net Working Capital. Subject to the last sentence of this Section 3.2(d), if the Adjustment Amount is positive, the Adjustment Amount shall be paid by Parent via wire transfer of immediately available funds to the bank account designated by Seller. If the Adjustment Amount is negative, the Adjustment Amount shall be paid by Seller via wire transfer of immediately available funds to the bank account designated by Parent. All payments shall be made together with interest at the rate of 6% per annum, which interest shall begin accruing on the Closing Date and end on the date that the payment is made. Within five Business Days after the calculation of the Closing Net Working Capital becomes binding and conclusive on the parties, Seller or Parent, as the case may be, shall make the wire transfer payment provided for in this Section 3.2(d). Notwithstanding the foregoing, neither the Seller nor the Parent, as the case may be, shall have any liability to pay any Adjustment Amount to the other unless the aggregate Adjustment Amount due by the Seller or the Parent, as the case may be, exceeds $750,000 (the “Adjustment Floor”).

(e) Parent and Buyer agree that Seller is providing the Audited Financial Statements and the Closing Balance Sheet solely for the purpose of enabling Parent to comply with its public reporting obligations under applicable securities laws and not as an independent basis on which Parent or Buyer made the decision to complete the transactions contemplated by this Agreement. The Parties agree that differences between the Audited Financial Statements and the financial information covered by Section 4.17(a) shall not entitle Buyer or Parent to make a claim for any breach of the representations and warranties in such Section 4.17(a).

Schedule 4.33 sets forth a list of all insurance policies, fidelity and surety bonds and fiduciary liability policies covering the Purchased Assets, the AAE Purchased Assets, the Business or the Employees (the “Insurance Policies”), and true and complete copies of all such Insurance Policies have been delivered by Seller to Buyer. Schedule 4.33 sets forth a true and complete list of Claims made in respect of Insurance Policies during the three (3) years prior to the date hereof that related to Business. There is no Claim pending under any of such Insurance Policies as to which coverage has been questioned or denied. There is no Claim pending under any of the Insurance Policies as to which coverage has been questioned. All premiums due under all Insurance Policies have been paid and Seller and the Acquired Aether Entities are in compliance with the terms and conditions of all such Insurance Policies, in all material respects. All Insurance Policies are in full force and effect. To Seller’s Knowledge, there are no threatened termination of, premium increase with respect to, or uncompleted requirements under, any Insurance Policy. No premiums are or will be payable by Buyer under the Insurance Policies after the Closing in respect of insurance provided for periods prior to the Closing Date, except as accrued on the September 30 Net Working Capital Statement. The Purchased Assets, the AAE Purchased Assets and the Business are insured under such Insurance Policies in amounts and against risks usually insured against by Persons operating businesses similar to the Business.

Except as described on Schedule 4.34: (a) each product sold, leased or delivered, or service provided, by Seller and the Acquired Aether Entities in the Business has been in material conformity with all applicable Contractual commitments and all express and implied warranties, and (b) Seller and the Acquired Aether Entities do not have any Liability (and there is no pending or, to the Seller’s Knowledge, threatened Claim that could reasonably be expected to give rise to any Liability) for replacement or repair thereof or other Losses in connection therewith. Schedule 4.35 includes copies of the standard terms and conditions of sale or lease for Seller (containing applicable guaranty, warranty, and indemnity provisions).

Seller is not in breach or default under the U.S. Real Property Lease, and to Seller’s Knowledge, no event has occurred or circumstance exists which, with the delivery of notice, the passage of time or both, would constitute such a breach or default, except to the extent such breach or default would not have a Material Adverse Effect on the Business. To Seller’s Knowledge, the landlord(s) under the Real Property Leases are in full compliance with the terms of the Real Property Leases, and no uncured default by any such landlord(s) has occurred. Neither the Seller nor any of the Acquired Aether Entities owns, leases or uses any property in the United States of America other than the U.S. Leased Real Property.

To Seller’s Knowledge, no party other than Seller or any Acquired Aether Party (as the case may be) has any oral or written right to lease, sublease or otherwise occupy any portion of the Leased Real Property. All rents, license fees and all other monetary obligations, payables and outgoings which have become due and payable by Seller or any Acquired Aether Entity in respect of the U.S. Leased Real Property have been paid.

The Seller or one of the Acquired Aether Entities has duly performed and observed all covenants, conditions, agreements in accordance with the UK Lease and with all statutory requirements, planning consents, by-laws and orders affecting the UK Real Property, and neither Seller nor any Acquired Aether Entity has received notice of any breach of any such matter. Neither the Seller nor any of the Acquired Aether Entities owns, leases or uses any property in the United Kingdom other than the UK Real Property. All rents, license fees and all other monetary obligations, payables and outgoings which have become due pursuant to the UK Lease have been paid. There are no ongoing Claims relating to the UK Real Property and, to Seller’s Knowledge, no event has occurred and no circumstances exist which may result in any such Claims.

Seller shall be responsible for any failure to treat such information confidentially by such Persons. If this Agreement is terminated, Seller and its Affiliates will, and will use their reasonable best efforts to cause their respective Representatives to, destroy or deliver to Buyer, upon request, all documents and other materials, and all copies thereof, obtained by Seller or its Affiliates or on their behalf from Buyer or any of its subsidiaries in connection with this Agreement that are subject to such confidence.

Buyer covenants that to the extent any AAE Excluded Asset has not been removed from the Aether Acquired Entities as of the Closing, it will cooperate reasonably with, and cause the appropriate Aether Acquired Entities to cooperate reasonably with, Seller in conveying (without payment of additional consideration by Seller) such AAE Excluded Assets to Seller (or Seller’s Affiliate, as requested by Seller) or otherwise providing Seller or its Affiliate with the benefit of such AAE Excluded Asset (in each case at the expense of Seller).

(i) Transition.

Notwithstanding the foregoing, the Employees of the Acquired Aether Entities shall remain employees of the Acquired Aether Entities after the Closing.

(ii) Effective as of the Closing Date, Buyer will be responsible only for the obligations and associated Liabilities that arise pursuant to the continuation coverage requirements of COBRA as a result of “qualifying events,” as defined in COBRA, that occur with respect to Transferred Employees after the Closing Date.

Without limiting the generality of the foregoing, Buyer, Parent and Seller shall each file any Notification and Report Forms and related material that it may be required to file in connection with the transactions contemplated by this Agreement with the Federal Trade Commission and the Antitrust Division of the United States Department of Justice under the HSR Act and with any Foreign Antitrust Administrator under Foreign Antitrust Laws, shall each use its diligent efforts to obtain an early termination of the applicable waiting period, and shall each make any further filings pursuant thereto that may be necessary, proper or advisable. Each Party shall permit the other Party to review any communication given by it to, and consult with each other in advance of any meeting or conference with, any Governmental Authority or, in connection with any proceeding by a private party, with any other Person, and to the extent permitted by the applicable Governmental Authority or other Person, give the other Party the opportunity to attend and participate in such meetings and conferences, in each case in connection with the transactions contemplated hereby. Except as otherwise provided herein, Buyer and Seller shall bear the costs and expenses of their respective filings; provided that the costs and expenses associated with filings made on behalf of both Buyer and Seller shall be shared equally.

(b) Consents. (i) Seller shall, and shall cause the Acquired Aether Entities to, take such actions as are commercially reasonable and necessary, and Buyer and Parent shall reasonably cooperate with Seller in all material respects, to obtain any consent with respect to any Material Contract that is to be assigned to Buyer pursuant to this Agreement and requires consent for the assignment thereof and any other consent, novation, approval or waiver that is required to be obtained from parties to any Material Contract in connection with the consummation of the transactions contemplated hereby as of the Closing Date (the “Required Consents”); provided, however, that such actions by Seller or an Acquired Aether Entity shall not include any requirement of Seller or an Acquired Aether Entity to commence any litigation or offer or grant any accommodation (financial or otherwise) to any third party. (ii) Buyer shall pay all amounts owed to any licensor (“Licensor Fees”) incurred in connection with obtaining any consent, novation, approval or waiver for any Contract set forth on Schedule 4.11(e), and Seller shall not be required to reimburse or otherwise bear, and shall have no liability to Parent, Buyer or any other party for, any such Licensor Fees. Notwithstanding the foregoing, in the event Seller is unable, prior to the Closing Date, to obtain the consent, novation, approval or waiver of the other party to any Contract set forth on Schedule 4.11(e), Seller shall reimburse Parent or Buyer, as the case may be, for any charges, penalties or other fees, as well as reasonable, directly related costs and expenses (but not Licensor Fees) actually paid by Parent or Buyer, as the case may be, to such other party that result directly from such failure, but only in an amount not to exceed $250,000 in the aggregate for all such Contracts. It is understood and agreed that (A) the amount of any such charges, penalties or other fees, as well as costs or expenses, shall not be included in the calculation of, and shall not be subject to, the Minimum Loss under Section 8.7 or the other monetary limitations set forth in Section 8.7 and (B) Parent and Buyer shall not be entitled to indemnification for the amount of any such charges, penalties or other fees, or costs or expenses, in excess of $250,000 under Article 8 or any other provision hereunder.

(c) Amendment of Seller Disclosure Schedule. Seller, Parent and Buyer agree that, with respect to the representations and warranties of the Seller contained in Article IV hereof, the Seller shall have the continuing obligation until the Closing Date to supplement, modify or amend promptly the Seller Disclosure Schedule with respect to: (i) any matter occurring after the date hereof that, if existing or occurring on or before the date of this Agreement, would have been required to be set forth or described in the Seller Disclosure Schedule (the “Seller New Matters”), and (ii) other matters which are not Seller New Matters but should have been set forth or described in the Seller Disclosure Schedule as of the date hereof (the “Seller Other Matters”). Any such supplement, modification or amendment (i) that reflects a Seller New Matter shall qualify the Seller’s representations and warranties for all purposes of this Agreement, except for purposes of determining whether the conditions set forth in Article VII hereof have been fulfilled and (ii) that reflects one or more Seller Other Matters shall not qualify any of the Seller’s representations or warranties for any purpose under this Agreement, and shall be provided solely for informational purposes. On or before the Closing Date, the Seller will prepare and deliver to Buyer a copy of the Seller Disclosure Schedule revised to reflect any supplement, modification or amendment required pursuant to this Section 6.3(c). Seller shall use commercially reasonable efforts to deliver any such supplemented, modified or amended Seller Disclosure Schedule to Buyer at least five (5) Business Days before the Closing Date. If no supplemented, modified or amended Seller Disclosure Schedule satisfying the

foregoing requirements is provided by Seller, the Seller Disclosure Schedule as delivered upon the execution of this Agreement shall continue to apply.

(d) Amendment of Buyer Disclosure Schedule. Seller and Buyer agree that, with respect to the representations and warranties of the Buyer contained in Article V hereof, the Seller shall have the continuing obligation until the Closing Date to supplement, modify or amend promptly the Buyer Disclosure Schedule with respect to: (i) any matter occurring after the date hereof that, if existing or occurring on or before the date of this Agreement, would have been required to be set forth or described in the Buyer Disclosure Schedules (the “Buyer New Matters”), and (ii) other matters which are not Buyer New Matters but should have been set forth or described in the Buyer Disclosure Schedule as of the date hereof (the “Buyer Other Matters”). Any such supplement, modification or amendment (i) that reflects a Buyer New Matter shall qualify the Buyer’s and Parent’s representations and warranties for all purposes of this Agreement, except for purposes of determining whether the conditions set forth in Article VII hereof have been fulfilled and (ii) that reflects one or more Buyer Other Matters shall not qualify any of the Buyer’s representations or warranties for any purpose under this Agreement, and shall be provided solely for informational purposes. On or before the Closing Date, the Buyer will prepare and deliver to Seller a copy of the Buyer Disclosure Schedule revised to reflect any supplement, modification or amendment required pursuant to this Section 6.3(d). The Buyer and Parent shall use commercially reasonable efforts to deliver any such supplemented, modified or amended Buyer Disclosure Schedule to Buyer at least five (5) Business Days before the Closing Date. If no supplemented, modified or amended Buyer Disclosure Schedule satisfying the foregoing requirements is provided by Buyer, the Buyer Disclosure Schedule as delivered upon the execution of this Agreement shall continue to apply.

(e) Notices of Certain Events. Prior to the Closing Date, Seller, on the one hand, and Buyer and Parent, on the other hand, shall promptly notify the other of:

(i) any notice or other communication from any Person alleging that the consent of such Person is or may be required in connection with the transactions contemplated herein;

(ii) any notice or other oral or written communication from any Governmental Authority in connection with the transactions contemplated herein or relating to Business;

(iii) any event, condition or circumstance occurring from the date hereof through the Closing Date that would constitute a violation or breach of any representation or warranty, whether made as of the date hereof or as of the Closing Date, or that would constitute a violation or breach of any covenant of any Party;

(iv) any failure of Seller, Buyer or Parent as the case may be, to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it hereunder;

(v) any change that has had or is reasonably expected to have a Material Adverse Effect, or could delay or impede the ability of any of Seller or Buyer to

perform its obligations pursuant to this Agreement and to consummate the transactions contemplated herein.

(f) Public Announcements. Neither Buyer, Parent or Seller nor any of their respective Affiliates or Representatives shall issue or cause the publication of any press release or other announcement with respect to the transactions contemplated by this Agreement, without the prior approval of the other Party, which approval shall not be unreasonably withheld, except as may be required by Applicable Laws or by any listing agreement with a national securities exchange or NASDAQ. In the case of an announcement required by Applicable Laws or by a listing agreement, the Party required to make such announcement shall use reasonable efforts to provide the other Party with a copy of the proposed announcement prior to its release and will give due consideration to such comments as such other Party may have.

(g) Delivery of Property Received After Closing. After the Closing, (a) Seller shall promptly transfer to Buyer, from time to time, any cash or other property received or held by Seller or any of its Affiliates that is associated with or relates to the Purchased Assets, the AAE Purchased Assets or the Business and (b) Buyer promptly shall transfer to Seller, from time to time, any cash or other property received or held by Buyer or Parent that is associated with or related to the Excluded Assets or the AAE Excluded Assets.

(h) Post Closing Tax Matters.

(i) Seller will be responsible for the preparation and filing of all Tax Returns for all periods ending on or prior to the Closing Date as to which Tax Returns are due after the Closing Date (including the consolidated, unitary, and combined Tax Returns for Seller which include the operations of the Business for any period ending on or before the Closing Date). Seller will make all payments required with respect to any such Tax Return; provided, however, that Buyer will indemnify Seller pursuant to Article IX for any such Taxes that are Assumed Liabilities. For the avoidance of doubt, this Section 6.3(h)(i) shall not apply to Aether European Holdings and other Acquired Aether Entities.

(ii) Buyer will be responsible for the preparation and filing of all Tax Returns for the Business for all periods ending after the Closing Date as to which Tax Returns are due after the Closing Date including Tax Returns for the Straddle Period. Buyer shall permit Seller to review and comment on each such Tax Return described in the preceding sentence prior to filing. Buyer will make all payments required with respect to any such Tax Return; provided, however, that Seller will indemnify the Buyer to the extent any payment the Buyer is making is a Tax attributable to a taxable period ending on or before the Closing Date based on the principles in Section 9.1(c), except to the extent that such Taxes are Assumed Liabilities. For the avoidance of doubt, this Section 6.3(h)(ii) shall not apply to Aether European Holdings and other Acquired Aether Entities:

(iii) With respect to Aether European Holdings and all other Acquired Aether Entities:

(A) Seller will be responsible for the preparation and filing of all Tax Returns for all periods ending on or prior to the Closing Date as to which Tax Returns

are due after the Closing Date. Seller will make all payments required with respect to any such Tax Return.

(B) Buyer will be responsible for the preparation and filing of all Tax Returns for all periods ending after the Closing Date as to which Tax Returns are due after the Closing Date including Tax Returns for the Straddle Period. Buyer shall permit Seller to review and comment on each such Tax Return described in the preceding sentence prior to filing. Buyer will make all payments required with respect to any such Tax Return and Seller shall not be liable for any Taxes with respect to such Tax Returns, except as otherwise provided in Article IX.

(C) Except to the extent required by Applicable Laws, Buyer shall not permit Aether European Holdings and any other Acquired Aether Entity to take any action after the Closing Date which could increase the Seller’s Liability for Taxes (including any Liability of the Seller to indemnify the Buyer for Taxes pursuant to this Agreement).

(D) Except to the extent required by Applicable Laws, Buyer shall not, without prior written consent of the Seller, amend any Tax Return filed by, or with respect to, Aether European Holdings and any other Acquired Aether Entity for any taxable period, or portion thereof, beginning before the Closing Date.

(iv) This Section 6.3(h)(iv) shall apply to both the Purchased Assets and to Aether European Holdings and other Acquired Aether Entities. Each Party shall, at its own expense, control any tax audit or examination by any Governmental Authority, and have the right to initiate any claim for refund or amended return, and contest, resolve and defend against any assessment, notice of deficiency or other adjustment or proposed adjustment of Taxes (“Proceedings”) for any taxable period for which that Party is charged with payment or indemnification responsibility under Article IX. Each Party shall promptly forward to the other Party all written notifications and other written communications, including (if available) the original envelope showing any postmark, from any Governmental Authority received by such Party relating to any Liability for Taxes for any taxable period for which such other Party is charged with payment or indemnification responsibility under Article IX. Each Indemnifying Party shall promptly notify, and consult with, each Indemnified Party as to any action it proposes to take with respect to any Liability for Taxes for which it is required to indemnify the Indemnified Party. The Indemnified Party shall not enter into any closing agreement or final settlement with any Governmental Authority with respect to any such Tax Liability without the written consent of the Indemnifying Party, which consent shall not be unreasonably withheld. In the case of any proceedings relating to any Straddle Period, the Parties shall jointly control such proceedings and shall cooperate with each other as to the conduct of such proceedings. Each Party shall, at the expense of the requesting Party, execute or cause to be executed any powers of attorney or other documents reasonably requested by such requesting Party to enable it to take any and all actions such Party reasonably requests with respect to any proceedings which the requesting Party controls. The failure by a Party to provide timely notice under this subsection shall relieve the other Party from its indemnification obligations with respect to the subject matter of any notification not timely forwarded, to the extent the other Party has suffered a loss or other economic detriment because of such failure to provide notification in a timely fashion.

(i) Further Assurances. Upon the terms and subject to the conditions set forth in this Agreement, each of the Parties shall use their respective commercially reasonable efforts to take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with the other Parties in doing, all things necessary, proper or advisable to consummate and make effective, in the most expeditious manner practicable, the transactions contemplated by this Agreement, including the execution and delivery of any additional instruments reasonably necessary to consummate the transactions contemplated by this Agreement and to fully carry out the purposes of this Agreement.

(j) Post Closing Accounts Receivable. After the Closing Date and continuing for a period of eighteen (18) months thereafter, Buyer shall in accordance with commercially reasonable business practices that are not materially less diligent than those used by the Parent with respect to its own business operations, attempt to collect (and shall cause the Aether Acquired Entities to attempt to collect) the Accounts Receivable existing on the Closing Date (“Closing Date Accounts Receivables”). In determining the collectability of Closing Date Accounts Receivable, the Parties agree that all amounts collected after the Closing shall be applied to the oldest accounts first, unless an account debtor specifies that any one or more of the payments made by such account debtor is being made with respect to a particular outstanding Accounts Receivable of such account debtor, in which case such payment shall be applied as such account debtor so specifies. To the extent that Buyer receives payment from Seller under Article VIII in respect of any uncollected Closing Date Accounts Receivable (each such Account Receivable, a “Reimbursed Receivable”), Buyer shall transfer to Seller all remaining records pertaining to such Reimbursed Receivable and Seller shall be thereafter entitled to collect such Reimbursed Receivable for its own account. If after payment by Seller, any Reimbursed Receivable is collected by or on behalf of Buyer (including by any of the Aether Acquired Entities), Buyer shall promptly pay (or cause to be paid) over to Seller the amount collected.

(k) Lessor Consent. Each of Parent, Buyer and Seller shall take all commercially reasonable efforts, and shall reasonably cooperate in such effort, to obtain a consent from the lessor of the US Leased Property with respect to (i) the assignment of the US Lease to Buyer and (ii) the Sublease.

(l) Right to Use Certain Software. Seller shall pay all costs, expenses and fees (except any internal costs or expenses of Parent or Buyer, as the case may be) charged by the owner or licensor to obtain the right for Buyer to use the MarketFirst software (from Pivotal Corporation) and the StarTeam software (from Borland Software Corporation) in connection with the Business so that it operates substantially in the form as currently used and configured by Seller.

(m) Transition Services Agreement. Each of Parent and Seller acknowledges that the draft Transition Services Agreement attached hereto as Exhibit C represents the state of negotiation between the parties as of the execution of this Agreement and agrees to negotiate in good faith and to finalize the terms of a definitive Transition Services Agreement mutually acceptable to both Parties within five (5) Business Days of the execution of this Agreement.

Section 8.4 Procedure for Indemnification – Third Party Claims.

(a) Promptly after receipt by any Party entitled to indemnity hereunder of the commencement of any Claim against such Party (the “Indemnified Party”), such Indemnified Party will, if a Claim is to be made against an indemnifying party under this Article VIII, give notice to the party obligated to provide indemnification pursuant to this Article VIII (the “Indemnifying Party”) of the commencement of such Claim, specifying the factual basis of the Claim and the amount thereof in reasonable detail to the extent then known by such Indemnified Party, but the failure to notify the Indemnifying Party will not relieve the Indemnifying Party of

any Liability that it may have to any Indemnified Party, except to the extent that the Indemnifying Party is actually prejudiced by the Indemnified Party’s failure to give such notice.

(b) If any third party Claim referred to in Section 8.4(a) is brought against an Indemnified Party, the Indemnified Party shall give notice to the Indemnifying Party of the commencement of such third party Claim within ten (10) Business Days after receipt by such Indemnified party of notice of the third party Claim. Thereafter, the Indemnified Party shall deliver to the Indemnifying Party, within five (5) Business Days’ after receipt thereof, copies of all notices and documents (including court papers) received by the Indemnified Party relating to the Third Party Claim. The Indemnifying Party will be entitled to participate in the defense of such third party Claim and, if it so chooses to assume the defense thereof with counsel selected by the Indemnifying Party, and reasonably acceptable to the Indemnified Party, if the Indemnifying Party gives written notice to the Indemnified Party of its election to assume the defense of such third party Claim within ten (10) Business Days after receiving notice thereof but only if: (i) the Indemnifying Party provides the Indemnified Party with evidence reasonably acceptable to the Indemnified Party that the Indemnifying Party will have the financial resources to defend against the Liabilities asserted in or ultimately resulting from the third party Claim and fulfill its indemnification obligations hereunder; (ii) the Liabilities asserted in the third party Claim involves only money damages and do not seek an injunction or other equitable relief; and (iii) settlement of, or an adverse judgment with respect to, the Liabilities asserted in or ultimately resulting from the third party Claim shall not, in the reasonable good faith judgment of the Indemnified Party, be likely to establish a precedential custom or practice materially adverse to the continuing business interests of the Indemnified Party. If the Indemnified Party assumes the defense against any third party Claim described in clauses (ii) or (iii), the Indemnifying Party will not be bound by any determinations with respect to such third party Claims without its prior written consent, which consent shall not be unreasonably withheld. After notice from the Indemnifying Party to the Indemnified Party of its election to assume the defense of such third party Claim (at its own expense and with its own counsel reasonably satisfactory to the Indemnified Party), the Indemnifying Party will not, as long as the Indemnifying Party diligently conducts such defense, be liable to the Indemnified Party under this Article VIII for any fees of other counsel or any other expenses with respect to the defense of such third party Claim, in each case subsequently incurred by the Indemnified Party in connection with the defense of such third party Claim unless the Indemnifying Party is also a party to such third party Claim, and counsel to the Indemnified Party determines in good faith and advises the Indemnifying Party that joint representation would give rise to a conflict of interest under (x) applicable standards of professional responsibility, or (y) because the Indemnified Party has or may have one or more defenses or counterclaims that are inconsistent with one or more of those that may be available to the Indemnifying Party in respect of such third party Claim. If the Indemnifying Party assumes the defense of a third party Claim, (i) no compromise or settlement of such third party Claim may be effected by the Indemnifying Party without the Indemnified Party’s consent unless (A) there is no finding or admission of any violation by any Indemnified Party of any Applicable Law or any violation by any Indemnified Person of the rights of any Person, and (B) the sole relief provided is monetary damages that are paid in full by the Indemnifying Party; (ii) the Indemnifying Party will have no Liability with respect to any compromise or settlement of such third party Claim effected without the Indemnifying Party’s consent (which shall not be unreasonably withheld or delayed); and (iii) the Indemnified Party will cooperate, at the expense of he Indemnifying Party, as the Indemnifying Party may reasonably request in investigating,

defending and (subject to clause (i)) settling such third party Claim. If the Indemnifying Party elects not to defend a third party Claim, is not permitted to defend such third party Claim by reason of the subparagraphs (a) or (b) above of this Section 8.4(b) or fails to notify the Indemnified Party of its election as herein provided, the Indemnified Party may pay, compromise, settle or defend such third party Claim at the sole cost and expense of the Indemnifying Party if the Indemnifying Party is determined to be liable to the Indemnified Party hereunder. In any event, the Indemnified Party and the Indemnifying Party may participate, at their own expense, in the defense of any third party Claim.

Section 8.5 Procedure for Indemnification – Other Claims. A Claim for indemnification for any matter not involving a third party Claim may be asserted by notice from the Indemnified Party to the Indemnifying Party. Such notice shall specify the factual basis of such Claim and the amount thereof in reasonable detail to the extent then known by the Indemnified Party.

Section 8.6 Time Limitations; Indemnification by Securityholders. If the Closing occurs, the Indemnifying Party shall have no Liability pursuant to Section 8.2 or Section 8.3 or of this Agreement unless an Indemnified Party gives notice to the Indemnifying Party of an actual Claim under Section 8.2 or Section 8.3 within the applicable timeframe, if any, specified in Section 8.1, which notice shall specify the factual basis of that Claim in reasonable detail to the extent then known by such Indemnified Party.

Section 8.7 Monetary Limitations. Subject to the last sentence of this Section 8.7, Seller shall not be required to indemnify Buyer Indemnitees, and shall not have any Liability under Section 8.2(a), until the aggregate amount of all Losses under Section 8.2(a) exceeds $200,000 (the “Minimum Loss”), and then only to the extent such aggregate Losses exceed the Minimum Loss. Subject to the following sentence, the aggregate amount of each of Seller’s liability for Losses under Section 8.2(a) and Buyer’s and Parent’s aggregate liability for Losses under Section 8.2(b) shall be limited in each case to an amount equal to 40% of the Purchase Price. The limitations set forth in this Section 8.7 will not apply to any Claims for indemnification in connection with, arising out of, or which would not have occurred but for:

(a) a breach of the representations and warranties contained in Section 4.1, Section 4.2, Section 4.3, Section 4.5, Section 4.8, Section 4.14, Section 4.15, Section 4.19, Section 4.23, Section 4.25(a) (but excluding clause (ii) thereof), Section 4.25(b), Section 4.25(c), Section 4.29, Section 5.1, Section 5.2, Section 5.4 and Section 5.6;

(b) fraud; or

(d) covenants to be performed in whole or in part, post-Closing.

Notwithstanding the foregoing or anything to the contrary set forth herein, the aggregate amount of Seller’s liability shall be limited to an amount equal to the Purchase Price in respect of all Claims for indemnification in connection with, arising out of, or which would not have occurred but for, a breach of the representations and warranties contained in Section 4.4, Section 4.13 and Section 4.15; and (ii) the amount of Seller’s liability for a breach of the representations

and warranties contained in Section 4.19 shall be limited to, and determined by, a recalculation of the Closing Net Working Capital and the Adjustment Amount as if such Losses existed on the Closing Date (giving effect to any and all prior payments made pursuant to Section 3.2(d) in connection with the Purchase Price adjustment and any and all prior payments made pursuant to this clause (ii)), and no Losses shall be recoverable until and unless the aggregate amount of such Losses (for which no indemnification has been made and no adjustment was made in connection with the Purchase Price adjustment pursuant to Section 3.2(d)) exceeds on a cumulative basis the Adjustment Floor (as increased or reduced by any payment made in connection with the Purchase Price adjustment pursuant to Section 3.2(d) and the aggregate amount of all prior payments made pursuant to this clause (ii)), and then Seller’s indemnification liability shall only be the amount of the excess of such Losses over the Adjustment Floor (as adjusted as described above). It is understood and agreed that the purpose of the foregoing clause (ii) is to treat any Losses resulting from a breach of the representations and warranties contained in Section 4.19 as if such Losses existed on the Closing Date and were included in the calculation of the Closing Net Working Capital in determining the Adjustment Amount and any required payments under Section 3.2(d), and to require any payments that would have been required to be made in connection with the Purchase Price adjustment under Section 3.2(d) if such Losses existed on the Closing Date (and such payments hereunder shall equal, and in no event exceed, the amount that would have been required to be paid under Section 3.2(d) in connection with the Purchase Price adjustment if such Losses existed on the Closing Date).

Section 8.8 Losses Net of Insurance; Taxes. The amount of any Losses for which indemnification is provided under Article VIII or Section 9.1 shall be net of (i) any amounts recovered by the Indemnified Party or any of its Affiliates pursuant to any indemnification by or indemnification agreement with any third party, (ii) any insurance proceeds or other cash receipts or sources of reimbursement received from the Indemnified Party or any of its Affiliates as an offset against such Losses (each source named in clauses (i) and (ii), a “Collateral Source”), and (iii) an amount equal to the present value of the net Tax benefit or net Tax cost, if any, available to or taken by the Indemnified Party or any of its Affiliates attributable to such Loss. The parties acknowledge and agree that no right of subrogation shall accrue or inure to the benefit of any Collateral Source hereunder. The Indemnifying Party may require an Indemnified Party to assign the rights to seek recovery pursuant to the preceding sentence; provided, that the Indemnifying Party will then be responsible for pursuing such recovery at its own expense. If the amount to be netted under this Section 8.8 from any payment required under Article VIII is determined after payment by the Indemnifying Party of any amount otherwise required to be paid to an Indemnified Party pursuant to this Article VIII, the Indemnified Party shall repay to the Indemnifying Party, promptly after such determination, any amount that the Indemnifying Party would not have had to pay pursuant to this Article VIII had such determination been made at the time of such payment. For purposes of Article VIII or Section 9.1, the amount of the Loss relating to any item included as a liability in calculating the Closing Net Working Capital shall be calculated net of the amount so included.

Section 8.9 Purchase Price Adjustment. All indemnification payments under this Article VIII shall be deemed adjustments to the Purchase Price for federal Tax purposes unless otherwise required by a determination made by a Governmental Authority.

Section 8.10 No Double Recovery. Notwithstanding the fact that any Party may have the right to assert Claims for indemnification under or in respect of more than one provision of this Agreement or another agreement entered into in connection herewith in respect of any fact, event, condition or circumstance, no Party shall be entitled to recover the amount of any Losses suffered by such Party more than once under all such agreements in respect of such fact, event, condition or circumstance, and an Indemnifying Party shall not be liable for indemnification to the extent the Indemnified Party has otherwise been fully compensated on a dollar for dollar basis for such Losses pursuant to the Purchase Price adjustment under Section 3.2(d).

ARTICLE IX
TAX LIABILITY

Section 9.1 Liability for Taxes.

(a) Buyer shall be liable for, and shall indemnify Seller Indemnitees against, all Taxes arising or resulting from (i) the conduct of the Business or the ownership of the Purchased Assets for taxable periods or portions thereof beginning after the Closing Date or (ii) any transaction relating to the Business or the Purchased Assets that Buyer or any of its Affiliates causes to occur on or after the Closing Date (excluding, subject to Section 3.7, the sale of the Business and the Purchased Assets to Buyer and the assumption of the Assumed Liabilities by Buyer pursuant to this Agreement).

(b) Seller shall be liable for and agrees to indemnify, defend and hold Buyer Indemnitees harmless from (i) any Tax imposed on any Acquired Aether Entity if and to the extent that such Tax arises in respect of a taxable period ended on or before the Closing (a “Tax Indemnity Period”), (ii) any Tax that constitutes a lien or Encumbrance on the Purchased Assets if and to the extent that such Tax arises in respect of a Tax Indemnity Period, (iii) any Tax or other Losses resulting from the inaccuracy or breach of any representation or warranty set forth in Section 4.14 or the breach of any covenants set forth in Section 6.3(h), and (iv) any costs and expenses (including, without limitation, reasonable expenses of investigation and attorneys’ fees and expenses) arising out of the imposition or assessment of any Tax, Losses or other costs described in clause (i), (ii) or (iii) (“Other Costs”), and the filing of any Returns for a taxable period ending on or before the Closing Date, including those incurred in the contest of good faith of any such imposition, assessment or assertion. Any Tax imposed as a result of the sale of the Business and the Purchased Assets to Buyer and the assumption of the Assumed Liabilities by Buyer pursuant to this Agreement shall be deemed to arise in respect of a Tax Indemnity Period.

(c) For purposes of subsections (a) and (b) of this Section 9.1, whenever it is necessary to determine the Liability for Taxes for a Straddle Period, such Taxes shall be apportioned between Seller and Buyer (A) in the case of Taxes other than income, sales and use and withholding taxes, on a per diem basis and (B) in the case of income, sales and use and withholding taxes, as determined as though the Straddle Period consisted of two taxable years or periods, one which ended on the Closing Date and the other which began at the beginning of the day following the Closing Date.

(d) Buyer shall pay to Seller the amounts received by Buyer or any of its Affiliates of any refund, abatement or credit of (A) Taxes which are attributable to the conduct of

the Business or the ownership of the Purchased Assets on or prior to the Closing Date and (B) any other Tax Assets. In the case of any Straddle Period, Buyer shall pay to Seller the amount received by Buyer or any of its Affiliates of any refund, abatement or credit of Taxes that would have been made had the Taxable Period ended on the Closing Date.

(e) Any assessment or other Claim by a Governmental Authority seeking to enforce or collect a Tax, Losses or Other Costs described in Section 9.1 shall be subject to the provisions of Section 8.4, 8.5, 8.6, 8.8 and 8.9 of this Agreement to the extent that Section 6.3(h)(iv) does not apply to such assessment or Claim.

(f) For the avoidance of doubt, notwithstanding any other contrary provisions of this Agreement, Seller shall not be liable for any Taxes or related Losses to the extent such Taxes or related Losses have been included as a liability in calculating the Closing Net Working Capital, or such Taxes or Losses are included in Assumed Liabilities.

ARTICLE X
RECORDS/LITIGATION AND TAX MATTERS

Section 10.1 Records/Litigation.

(a) For a period of five (5) years after the Closing Date, in the event and for so long as any Party or any Acquired Aether Entity or any of their respective Affiliates is contesting or defending against any Claim in connection with (i) any transaction contemplated under this Agreement or (ii) any fact, situation, circumstance, status, condition, activity, practice, plan, occurrence, event, incident, action, failure to act, or transaction on or prior to the Closing Date involving any Party or any Acquired Aether Entity or any of their respective Affiliates, the other Party or Acquired Aether Entity, as the case may be, will cooperate with the contesting or defending party and its counsel in the contest or defense, make available its personnel, and provide such testimony and access to its Books and Records as shall be reasonably necessary in connection with the contest or defense, all at the sole cost and expense of the contesting or defending party (unless the contesting or defending party claims to be entitled to indemnification therefor under Article VIII or Article IX).

(b) For a period of five (5) years after the Closing Date, each Party shall provide such assistance as the other Party may from time to time reasonably request in connection with the preparation of Tax Returns required to be filed, any audit or other examination by any taxing authority, any judicial or administrative proceeding relating to Liability for Taxes, or any claim for refund in respect of such Taxes or in connection with any litigation and proceedings related to the Business, including making available documents, witnesses, employees for interviews, litigation preparation and testimony. The requesting party shall reimburse the assisting party for the out-of-pocket costs incurred by the assisting party.

Section 10.2 Tax Disclosure Authorization. Notwithstanding the Confidentiality Agreement or anything herein to the contrary, the Parties (and each Affiliate and Person acting on behalf of any Party) agree that each Party (and each Representative of such Party) may disclose to any and all Persons, without limitation of any kind, the transaction’s tax treatment and tax structure (as such terms are used in Code §§6011 and 6112 and regulations thereunder)

contemplated by this Agreement and all materials of any kind (including opinions or other tax analyses) 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 Laws; provided, however, that such disclosure may not be made until the earlier of date of (A) public announcement of discussions relating to the transaction, (B) public announcement of the transaction, or (C) execution of an agreement to enter into the transaction. This authorization is not intended to permit disclosure of any other information including (without limitation) (A) any portion of any materials to the extent not related to the transaction’s tax treatment or tax structure, (B) the identities of participants or potential participants, (C) the existence or status of any negotiations, (D) any pricing or financial information (except to the extent such pricing or financial information is related to the transaction’s tax treatment or tax structure), or (E) any other term or detail not relevant to the transaction’s tax treatment or the tax structure.

TERMINATION RIGHTS

Section 11.1 Termination Rights. This Agreement may be terminated at any time prior to the Closing as follows and in no other manner:

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

(b) after January 31, 2004 by either Seller or Parent, if the Closing has not occurred by that date and if failure to close is not the result of a breach of this Agreement; provided that if Parent has not completed the Private Financing, it shall not be permitted to terminate this Agreement pursuant to this Section 11.1(b) unless (i) if Parent has entered into definitive agreements for the Private Financing, such Private Financing shall have been completed and funded (or is not subject to any condition to funding other than the Closing), or (ii) if Parent has not entered into definitive agreements for the Private Financing, (x) Parent has complied in all respects with its obligations under Section 3.2(b) and Section 6.3(e) and (y) either (A) Seller has notified Parent that it does not wish to accept the Substitute Financing in lieu of cash consideration for the Purchase Price or (B) Seller has not entered into definitive agreements for the Substitute Financing by March 30, 2004;

(c) By Seller, if: (i) there has been a material misrepresentation or breach by Buyer or Parent of a representation or warranty contained herein and such material misrepresentation or breach, if curable, is not cured within ten (10) Business Days after written notice thereof from Seller; (ii) Parent or Buyer has committed a material breach of any covenant imposed upon it hereunder and, if curable, fails to cure such breach within ten (10) Business Days after written notice thereof from Seller; or (iii) any condition to Seller’s obligations hereunder becomes incapable of fulfillment through no fault of Seller and is not waived by Seller;

(d) By Parent, if: (i) there has been a material misrepresentation or breach by Seller of a representation or warranty contained herein and such material misrepresentation or breach, if curable, is not cured within ten (10) Business Days after written notice thereof from Parent; (ii) Seller has committed a material breach of any covenant imposed upon it hereunder and, if curable, fails to cure such breach within ten (10) Business Days after written notice

thereof from Parent; or (iii) any condition to Parent’s or Buyer’s obligations hereunder becomes incapable of fulfillment through no fault of Parent or Buyer and is not waived by Parent or Buyer;

(e) by Seller, if Seller determines to take any of the actions contemplated by subclauses (A) or (B) of Section 6.1(e) with respect to a Competing Transaction that is a Company Sale after having complied with the provisions of Section 6.1(e) and, concurrently with a termination pursuant to this Section 11.1(e), shall pay the Termination Fee owed pursuant to Section 11.3; and

(f) by Seller, at any time following Parent’s issuance of a Substitute Financing Notice.

In the event that a condition precedent to a Party’s obligation is not met, nothing contained herein shall be deemed to require any Party to terminate this Agreement, rather than to waive such condition precedent and proceed with the Closing.

Section 11.2 Effect of Termination. In the event of termination by Parent or Seller pursuant to this Article XI, written notice thereof shall forthwith be given to the other Party and the transactions contemplated by this Agreement shall be terminated, without further action by any Party, except as otherwise required by Section 11.3.

(a) Parent and Buyer shall return to Seller all documents and copies and other materials received from or on behalf of Seller relating to the transactions contemplated hereby, whether so obtained before or after the execution hereof;

(b) all confidential information received by Parent and Buyer with respect to the Purchased Assets, the Assumed Liabilities, the Acquired Aether Entities and the Business shall be treated in accordance with the terms and conditions of Section 6.2(a); and

(c) no Party hereto shall have any Liability or further obligation under this Agreement resulting from such termination except (i) that the provisions of Section 6.1(g), Section 6.2(a), Section 12.5, Section 12.10 and this Article XI shall remain in full force and effect; and no Party waives any Claim against a breaching Party to the extent such termination results from the breach by a Party of any of its representations, warranties, covenants or agreements set forth in this Agreement.

Section 11.3 Fee to Parent. If this Agreement is terminated by Seller pursuant to Section 11.1(e), then Seller shall promptly pay to Parent a termination fee of Twelve Million Dollars ($12,000,000) (the “Termination Fee”), in cash by wire transfer in immediately available funds to an account designated by Parent.
