To the extent the AT&T Receivables are insufficient to cover the entire amount of Buyer's Section 3.5(c)(i) payment obligations, Buyer shall make up such shortfall with any combination of (i) cash and (ii) an increase in the principal amount of the Notes, provided that after giving effect to such increase the ratio of (x) the principal amount of the Notes, after excluding any adjustment made pursuant to Section 3.6, to (y) the sum of the Purchase Price and the cash referred to in the preceding clause (i) shall not exceed 3:2. At Buyer's option, Buyer may require ATG to pay any amount required to be paid by ATG to Buyer pursuant to clause (c)(ii) of this Section 3.5 by any combination of (i) cash and (ii) a decrease in the aggregate principal amount of the Notes, provided that after giving effect to any such cash payment the ratio of (x) the aggregate principal amount of the Notes, after excluding any adjustment made pursuant to Section 3.6, to (y) (I) the Purchase Price minus (II) the amount of such cash payment shall not exceed 3:2. The amount of any payment that Buyer is required to make pursuant to Section 3.5(c)(i) that is satisfied by the assignment of AT&T Receivables shall be equal to the face amount of the AT&T Receivables so assigned, and the amount of any payment that Buyer or ATG is required to make pursuant to Section 3.5 (c)(i) or (ii), as the case may be, that is satisfied by an increase or a decrease in the principal amount of the Notes shall be the amount of such increase or decrease, as the case may be. If Buyer effects an assignment of any AT&T Receivables, all risk of collectibility and liability for any deficiencies shall be the sole responsibility of ATG. 3.6 Other Adjustments. (a) Eligible Fleet Agreements. In the event that prior to the Closing Date the Company and an Eligible Carrier enter into an Eligible Fleet Agreement, AWS shall cause the Company to promptly deliver a complete and correct copy thereof to Buyer (and in any case at least three Business Days prior to the Closing), together with a calculation in reasonable detail as to the adjustment to the Transaction Consideration resulting therefrom. The Transaction Consideration shall be increased by an amount equal to the sum of (i) $50,000 multiplied by the number of airplanes covered by such Eligible Fleet Agreement with respect to which a firm order has been placed and (ii) $10,000 multiplied by the number of airplanes covered by such Eligible Fleet Agreement with respect to which an option to order the services of the Company has been granted. Any such increase may be paid, at Buyer's option, by any combination of (i) an increase in the aggregate principal amount of the Notes or (ii) an increase in the ATG Payment; provided that in no case shall the ratio of the aggregate principal amount of the Notes to the Purchase Price exceed 4:1. 13 20 (b) Existing Carrier Agreements. In the event that prior to the Closing Date an Existing Carrier Agreement shall be terminated, the Company shall promptly give notice thereof to Buyer, together with a calculation in reasonable detail as to the adjustment to the Transaction Consideration resulting therefrom. The Transaction Consideration shall be decreased by an amount equal to $50,000 multiplied by the number of airplanes covered by such Eligible Fleet Agreement. Any such decrease shall be reflected by a decrease in the principal amount of the Notes. (c) Capital Expenditures. (i) At least three Business Days prior to the Closing, AWS shall provide to Buyer a statement setting forth in reasonable detail the Capital Expenditures made by the Company between November 1, 1998 and the FCC Consent Date. Buyer shall have 60 days from the Closing Date to object to such statement, in which case the provisions of Section 3.7(b) shall apply unless the parties otherwise agree. Once the amount of such Capital Expenditures is finally determined pursuant to Section 3.7, any adjustment due in respect thereof shall be paid in cash by the applicable party within 5 days following such determination. (ii) If the amount of the Capital Expenditures is less than the CapEx Target Amount, AWS shall pay to the Company, as an adjustment of the Cash Amount, an amount equal to such deficiency. If the amount of the Capital Expenditures exceeds the CapEx Target Amount, Buyer shall cause the Company to pay to AWS, as an adjustment of the Cash Amount, an amount equal to such excess. (iii) For purposes of this Section, "Capital Expenditures" means all costs associated with the acquisition and placing into service of all fixed assets and property of the Company, including but not limited to the labor, non-labor and equipment costs associated with installations of telephone and SATCOM systems on commercial aircraft, product development and network enhancements of ground and air network products, and investments in AirOne Canada installations, and excluding all costs allocated to the Company's program with SAS. All determinations concerning the designation of an item as a Capital Expenditure hereunder shall be made by the Company in accordance with GAAP and with the past practices and procedures of the Company. 3.7 Objections to Determination. (a) Initial Objections. If Buyer believes that any determination (including initial and revised calculations) made by AWS pursuant to Section 3.5 or 3.6 is incorrect, it may object thereto by delivering to AWS a statement of its objections in reasonable detail within 15 days after the delivery to it of the determination in question. Buyer and AWS shall attempt to resolve any such disagreement promptly, but if agreement has not been reached within 10 days of receipt of such 14 21 objections, the disagreement shall be resolved forthwith in accordance with the provisions of paragraph (b) of this Section 3.7. (b) Determination by Independent Accountant. (i) Any disagreement referred to in paragraph (a) above shall be submitted forthwith to arbitration by a nationally recognized independent accounting firm mutually agreed upon by KPMG Peat Marwick and PricewaterhouseCoopers (the "Independent Accountant"). Each party shall represent and warrant to the other that such Independent Accountant is not the independent auditor of such party or the ultimate parent of such party. (ii) The Independent Accountant shall as promptly as practicable make a determination of the items in dispute, which determination shall be final and binding upon the parties and shall be enforceable by a court of competent jurisdiction. The cost of the Independent Accountant shall be borne equally by AWS and Buyer. 3.8 Treatment of Adjustments. The parties agree to treat any adjustments made pursuant to Sections 3.5 or 3.6 as adjustments to the Transaction Consideration for United States federal, state, local and foreign tax purposes.

(j) With respect to flexible spending arrangements in which Company Employees participate, to the extent permitted under ERISA or the Code, the AWS Parties shall continue to apply amounts credited to the accounts of Company Employees for covered medical expenses to the extent that such expenses are incurred on or before the Closing Date and with respect to dependent care expenses to the extent such expenses are incurred on or before December 31 of the year in which the Closing Date occurs. 8.2 Access to Books and Records. (a) Access. On and after the Closing Date, Buyer shall cause the Company to give to the Sellers and their representatives such access as Sellers may reasonably request to the properties, books, records and employees of the Company relating to any period ending on or before the Closing Date, for purposes including but not limited to (i) preparing any Tax Return and financial statements and responding to Tax audits relating to the Company, or (ii) investigating, preparing the defense or prosecution of, prosecuting or defending any litigation proceeding, or investigation pending, threatened or anticipated by or against the Company or any of the Sellers, except in an action between the parties hereto; provided that (x) the normal conduct of the business of the Company shall not be disrupted thereby and (y) in the event of any litigation or threatened litigation between the parties, the foregoing shall in no event be, or be deemed to be, a waiver by a party of any right to assert the attorney-client privilege or other applicable privilege. Subject to the foregoing, such access shall include, without limitation, assuring the presence of a party's former employees as witnesses at depositions, hearings or trials. 37 44 (b) Maintenance of Records. For a period of six years after the Closing Date, Buyer shall cause the Company to maintain the books and records of the Company in existence as of the Closing Date. In the event AWS provides the Buyer or the Company with a written request to be provided with such books and records, prior to the end of such six year period, Buyer shall cause the Company to refrain from disposing of any such books or records covering periods prior to the Closing Date, and shall (at AWS' expense) provide such books and records to AWS instead of disposing thereof. 8.3 Tax Matters. (a) Liability for Taxes. (i) Except for the amount of Taxes described in clause (A), (B) or (C) of this clause (i) that is deducted in calculating the Final Working Capital in accordance with Schedule X, the AWS Parties shall be liable for and indemnify Buyer or the Company as the case may be, for all Taxes (A) imposed on the Company, or for which the Company may otherwise be liable, for any taxable year or period that ends on or before the Closing Date and, with respect to any portion of a taxable year or period beginning before and ending after the Closing Date ("Split Period"), the portion of such Split Period ending on and including the Closing Date, (B) for which the Company is held liable as a member of any combined, consolidated or unitary group of which the Sellers or any of its Affiliates (other than the Company) is or was a member pursuant to any federal, state, local or foreign law with respect to Taxes or (C) imposed as a result of the parties making an election pursuant to Section 338(h)(10) of the Code (including any similar election or inability to make such an election under any state or local statute corresponding to federal laws). (ii) The Company shall be liable for and Buyer shall indemnify Sellers for all Taxes imposed on Sellers with respect to the Company for any taxable year or period that begins after the Closing Date and, with respect to a Split Period, the portion of such Split Period beginning after the Closing Date. (b) Taxes for Short Taxable Year. For purposes of paragraph (a), whenever it is necessary to determine the liability for Taxes of the Company for a portion of a Split Period, the determination of the Taxes for the portion of the Split Period ending on, and the portion of the Split Period beginning after, the Closing Date, shall be determined by assuming that the Company had a taxable year or period that ended at the close of the Closing Date, except that any such Tax imposed annually based on ownership of assets on a particular date shall be prorated to the period to and including the Closing Date and the period thereafter. (c) Tax Refunds. Sellers shall be entitled to any refund of any Taxes, including interest paid thereon, if any, net of income taxes due thereon, with respect to periods ending on or before the Closing Date. AWS shall have the right to determine whether any claim for refund for such Taxes shall be made on behalf of Sellers by the Company. If AWS elects to make a claim for refund, the Buyer Parties and the Company shall cooperate fully in connection therewith. 38 45 Notwithstanding the foregoing, Sellers shall not be entitled make any claim for refund of Taxes which would adversely affect the liability for Taxes of Buyer or the Company for any period after the Closing Date to any extent (including, but not limited to, the imposition of income tax deficiencies, the reduction of asset basis or cost adjustments, the lengthening of any amortization or depreciation periods, the denial of amortization or depreciation deductions, or the reduction of loss or credit carryforwards) without the prior written consent of Buyer. Such consent shall not be unreasonably withheld, and shall not be necessary to the extent that Sellers have indemnified Buyer against the effects of any such settlement. Sellers shall reimburse Buyer and the Company for reasonable out-of-pocket expenses incurred in providing such cooperation. (d) Coordination. Without the prior written consent of Sellers (which consent may not be unreasonably withheld and shall not be necessary to the extent that Buyer has indemnified the Sellers against the effects of any such election or filing), neither Buyer, the Company, nor any Affiliate of Buyer shall (i) make any election or (ii) file any amended Tax Return or propose or agree to any adjustment of any item with the Internal Revenue Service or any other taxing authority with respect to any tax period ending on, before or including the Closing Date that would have the effect of increasing the liability for any Taxes or reducing any Tax benefit of Sellers or the Company. (e) Section 338(h)(10) Election. (i) Buyer and Sellers shall take all steps necessary to make a timely election under Section 338(h)(10) of the Code (and any comparable election under state or foreign tax law) with respect to Buyer's acquisition of the Shares from Sellers. Buyer and Sellers shall cooperate fully with each other in the making of such election. (ii) In particular and not by way of limitation, in order to effect such election, Buyer and Sellers shall jointly execute necessary copies of Internal Revenue Service Form 8023 and all attachments required to be filed therewith pursuant to applicable Treasury Regulations. Accordingly, Buyer and Sellers agree, on the Closing Date, to (x) enter into a Purchase Price Allocation Agreement (the "Allocation Agreement") providing for the allocation of the purchase price for tax purposes (as determined therein, the "Tax Purchase Price") consistent with the provisions of Section 338 of the Code and Treasury Regulations thereunder and (y) cooperate in the preparation of Form 8023 for timely filing in each of their respective federal income Tax Returns. For purposes of the Allocation Agreement, the allocation of the Tax Purchase Price to the assets of the Company shall be as agreed to by Buyer and AWS, or, if Buyer and AWS cannot agree, then the assets on which agreement has not been reached shall be subject to an appraisal by an independent appraiser which shall be acceptable to both parties. The amount of the Tax Purchase Price allocated to such assets so appraised shall be equal to their respective appraised fair market values. Unless otherwise prohibited by law, all foreign, federal, state and local income Tax returns filed by Buyer and the Sellers shall be filed consistently with the allocations made pursuant to the Allocation Agreement. 39 46 (f) Tax Returns. Sellers shall file or cause to be filed when due, including extensions thereof, all Returns that are required to be filed with respect to the Company for taxable years or periods ending on or before the Closing Date and shall pay any Taxes due in respect of such Returns, and Buyer shall file or cause to be filed when due all Returns that are required to be filed with respect to the Company for taxable years or periods beginning and ending after the Closing Date and shall pay any Taxes due in respect of such Returns. Sellers and Buyer shall jointly prepare and Buyer shall file or cause to be filed all Returns that are required to be filed with respect to the Company for any Split Period taxable year, and AWS and Buyer agree to negotiate and resolve in good faith any issue arising as a result of the preparation of such Tax Return. In the event the parties are unable to resolve any dispute prior to thirty (30) Business Days before the due date of such Tax Return, including extensions thereof, if a request for extension has been timely filed, AWS and Buyer shall jointly select a public accounting firm with nationally recognized tax expertise ("Tax Arbitrator") to resolve the dispute. If the Tax Arbitrator has not resolved the dispute within five (5) Business Days prior to the due date (including extensions) for the filing of the Tax Return in question, then Buyer may file such Tax Return in accordance with its position on such disputed issue without AWS' consent. Notwithstanding the filing of such Tax Return, the Tax Arbitrator shall make a determination with respect to any disputed issue, and the amount of Taxes for which Sellers are responsible pursuant to Section 8.3(b) shall be as determined by the Tax Arbitrator. The fees and expenses of the Tax Arbitrator shall be shared equally by Buyer and Sellers. Not later than five (5) Business Days before the due date for the payment of Taxes with respect to such Tax Return or (ii) in the event of a dispute five (5) Business Days after notice to Sellers of resolution thereof, Sellers shall pay to Buyer an amount equal to the Taxes allocable to Sellers pursuant to Section 8.3(b). Notwithstanding the foregoing, in the case of a dispute, Sellers shall pay to Buyer not later than five (5) Business Days before the due date for the payment of Taxes with respect to such Tax Return, the amount of Taxes that Sellers reasonably believe at such time is properly allocable to Sellers pursuant to Section 8.3(b). No payment pursuant to this Section shall exempt Sellers from their indemnification obligations pursuant to this Agreement if the amount of Taxes as ultimately determined (on audit or otherwise) for the periods covered by such Tax Returns that are the responsibility of Sellers exceeds the amount of Sellers' payment under this Section. (g) Contest Provisions. Whenever Buyer receives a notice of any pending or threatened audit or assessment for any taxable period for which Sellers are or may be liable under this Agreement, Buyer shall promptly inform Sellers in writing, provided that failure to comply with this provision shall not affect Buyer's right to indemnification hereunder. AWS shall have the right to control, at its own cost, any resulting proceedings and to determine whether and when to settle any such claim, assessment or dispute to the extent such proceedings or determinations affect the amount of Taxes for which Sellers are liable under this Agreement. Notwithstanding the foregoing, Sellers shall not be entitled to settle, either administratively or after the commencement of litigation, any claim for Taxes which would adversely affect the liability for Taxes of Buyer or the Company for any period after the Closing Date to any extent (including, but not limited to, the imposition of income tax deficiencies, the reduction of asset basis or cost adjustments, the lengthening of any amortization or depreciation periods, the denial of amortization or depreciation deductions, or the reduction of loss or credit carryforwards) without the prior written consent of Buyer. Such consent 40 47 shall not be unreasonably withheld, and shall not be necessary to the extent that Sellers have indemnified Buyer against the effects of any such settlement. Whenever any taxing authority sends a notice of an audit, initiates an examination of the Company or otherwise asserts a claim, makes an assessment or disputes the amount of Taxes (i) for any taxable period for which Buyer is liable under this Agreement or (ii) for any taxable period that involves an issue that could potentially affect a taxable period for which Buyer is or may be liable under this Agreement, Sellers shall promptly inform Buyer in writing, and Buyer shall have the right to control, at its cost, any resulting proceedings and to determine whether and when to settle any such claim, assessment or dispute, except to the extent such proceedings affect the amount of Taxes for which Sellers are liable under this Agreement. (h) Termination of Tax Allocation Agreements. Any tax allocation or sharing agreement or arrangement, whether or not written, that may have been entered into by AWS and the Company shall be terminated as to the Company as of the Closing Date, and no payments which are owed by or to the Company pursuant thereto shall be made thereunder. (i) Information to be Provided by Buyer. With respect to the taxable year of Sellers ending on the last day of the most recent full tax year and the period in tax year 1999 prior to and including the Closing Date, Buyer shall promptly cause the Company to prepare and provide to Sellers a package of tax information materials (the "Tax Package"), which shall be completed in accordance with past practice including past practice as to providing the information, schedules and work papers and as to the method of computation of separate taxable income or other relevant measure of income of the Company. Buyer shall cause the Tax Package for the portion of the taxable period ending on the Closing Date to be delivered to Sellers within one hundred twenty (120) days after the Closing Date. (j) Assistance and Cooperation. Each of Buyer and Sellers shall provide the other with such assistance as may reasonably be requested by each of them in connection with the preparation of any Tax Return, any audit or other examination by any taxing authority, or any judicial or administrative proceedings relating to liability for Taxes, and each shall retain and provide the other with any records or information which may be relevant to such Return, audit or examination, proceedings or determination. Such assistance shall include making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder and shall include providing copies of any relevant Tax Return and supporting work schedules. The party requesting assistance hereunder shall reimburse the other for reasonable expense incurred in providing such assistance. Without limiting in any way the foregoing provisions of Section 8.3 or this Section 8.3(j), Buyer hereby agrees that it shall retain, until the appropriate statutes of limitation (including any extensions) expire, copies of all Tax Returns, supporting work schedules and other records or information which it possesses and which may be relevant to such returns of the Company for all taxable periods ending on or prior to the Closing Date, and that such records shall be maintained until the expiration of the applicable statute of limitations, including any extensions thereto. Further, Buyer shall not destroy or otherwise dispose of such records without first providing Seller with a reasonable opportunity to review and copy such records. 41 48 (k) Survival of Obligations. Notwithstanding any other provision of this Agreement, the rights and obligations of the parties set forth in this Section 8.3 shall remain in effect without limitation as to time. 8.4 Contingent Payment. (a) In the event of a Sale Transaction (as defined below) occurring between the Closing Date and the date of the eighteen-month anniversary of the Closing Date (the "Value Period"), Buyer shall pay to Sellers, in accordance with the following provisions of this Section 8.4, an amount (the "Contingent Amount") equal to 80% of the positive difference, if any, between the "Equity Sale Value" and the "Applicable Value" (as such terms are defined below). For the purposes of this Agreement, the following terms shall have the following meanings: "Sale Transaction" means any of the following, whether in one transaction or in a series of transactions: (A) Buyer, or any of its Affiliates, transfers or disposes of, directly or indirectly, 49% or more of the capital stock of the Company, (B) the Company transfers or disposes of, directly or indirectly, 49% or more (by value) of its assets (excluding sales of inventory and other assets in the ordinary course of business), (C) the Company issues or sells any of its capital stock to, or consolidates with or merges with or into, another Person or enters into any other significant corporate transaction pursuant to which, directly or indirectly, 49% or more of the aggregate value of the interests of the Buyer, or any of its Affiliates, in the Company are transferred or disposed of or (D) the Company, the Buyer or any of its Affiliates enters into a binding agreement to consummate any such transaction, provided that (x) transfers or dispositions to the present shareholders of Buyer, or any of its Affiliates, or an entity of which more than 80% of the equity and voting power are owned directly or indirectly by one or more of such Persons, shall not be deemed to be transfers or dispositions constituting part of a Sale Transaction so long as the provisions of the last sentence of paragraph (b) below are complied with and (y) a merger, consolidation or business combination with an entity engaged in the same business as the Company or a business related thereto, in which Buyer receives equity in the surviving entity but not cash or securities of a class registered under the Securities Exchange Act of 1934, as amended (or securities or interests convertible into such securities), shall not be deemed a Sale Transaction. "Equity Sale Value" means the total value of the consideration paid or distributed to the Company or to the Persons who are directly or indirectly owners of the Company in the Sale Transaction in respect of the Company or its assets, including, without limitation, cash consideration and in-kind consideration, less fees and expenses attributable to the Sale Transaction payable from the Company or such owners, as the case may be, to Persons that are not Affiliates of Buyer or the Company, provided that in the case of a transaction in which the consideration is paid to the Company, in order to clarify the intent of the foregoing definition the parties agree that the value of extraordinary distributions paid to direct or indirect owners of the Company that have been financed by the incurrence of debt shall be considered to be value paid or distributed in a Sale Transaction. 42 49 "Applicable Value" means, with respect to a particular Sale Transaction the product of (i) the Purchase Price plus the aggregate amount of all dividends or other distributions (other than those in the form of additional capital stock of the Company) made by the Company in respect of any shares of any class of capital stock of the Company, whether in cash or property or obligations of the Company and (ii) the percentage interest in the Company or the Company's assets being transferred or disposed of directly or indirectly in such Sale Transaction. (b) Contemporaneously with the execution of a binding agreement with respect to any Sale Transaction, Buyer and the Company shall notify Sellers thereof, and shall furnish together with such notice a complete and correct copy of such binding agreement, and Buyer and the Company shall promptly provide such other information with respect thereto as may reasonably be requested by Sellers. The Contingent Amount shall be payable to Sellers at the same time as the consideration in the Sale Transaction is payable to the Company or the Buyer, as the case may be, and in the same form or (at the option of the Buyer or its Affiliates or the Company, as the case may be, upon at least thirty days' prior notice to Sellers) in cash or equivalent value as determined in accordance with paragraph (c) below, provided that payment of the Contingent Amount as provided herein shall be made on the closing date of the Sale Transaction and as a condition to the consummation thereof. In the event of any transfer or disposition of all or a substantial portion of the assets held directly or indirectly by the Company, or by Buyer or any of its Affiliates holding an interest in the Company, that does not constitute a Sale Transaction (whether in one transaction or a series of transactions), as a condition to such transfer or disposition such transferee shall assume the obligations of the Company or Buyer hereunder, as the case may be, and shall agree in writing to be bound by the terms of this Section 8.4, such writing to be in form and substance satisfactory to AWS. (c) In the event that any Sale Transaction provides for the payment of any non-cash consideration (including, without limitation, any deferred or contingent consideration) then, for the purposes of determining the Contingent Amount (if any) payable to Sellers pursuant to this Section 8.4, the amount of such non-cash consideration shall be deemed equal to the fair market value of such non-cash consideration as determined at least five (5) Business Days prior to the closing date of such Sale Transaction by an investment banking firm of recognized national standing (the "Appraiser") selected by Buyer (and having no material relationship with Buyer) and reasonably satisfactory to AWS. If any property (the "Other Assets") other than ownership in, or assets of, the Company, are proposed to be transferred in connection with any Sale Transaction, then, for purposes of determining the Contingent Amount (if any) payable to Sellers pursuant to this Section 8.4 the consideration in the Sale Transaction shall be deemed not to include any portion thereof allocable to such Other Assets, such allocation to be determined (and delivered to the Company and the Sellers) at least ten (10) Business Days prior to the closing date by the Appraiser. All fees, costs and other expenses of the Appraiser pursuant to this Section 8.4 shall be borne equally by Buyer and AWS. 8.5 Maintenance of Corporate Existence. Each of Buyer and Iridium agrees, for a period of nine months after the Closing Date, it shall preserve the corporate existence of Buyer, and 43 50 shall not transfer any of the Shares or all or substantially all the assets of the Company (by sale, merger or otherwise) (i) to a non-corporate entity or (ii) any entity which does not agree to be bound by the restrictions applicable to Buyer under this Section 8.5. 8.6 Confidentiality. Each of the Seller Parties agrees that following the Closing Date it and its Affiliates shall and shall cause its respective officers and directors and shall use reasonable efforts to cause all its other employees, auditors, attorneys, consultants, advisers and agents to, hold in strict confidence, unless compelled to disclose by judicial or administrative process or by other requirements of law and after prior written notice to Buyer, all confidential information of the Company in its respective possession and shall not release or disclose such confidential information of the Company in its respective possession to any other Person, except to its auditors, attorneys, financial advisors and other consultants, agents and advisors in connection with post-Closing matters hereunder or other matters as to which the Seller Parties have retained obligations or liabilities hereunder; provided that the foregoing obligations shall not apply to any such information which otherwise comes into the public domain. 8.7 Further Assurances. Following the Closing, the Seller Parties and the Buyer Parties shall, and shall cause each of their Affiliates to, from time to time, execute and deliver such additional instruments, documents, conveyances or assurances and take such other actions as shall be necessary, or otherwise reasonably requested by the other party, to confirm and assure the rights and obligations provided for in this Agreement and render effective the consummation of the Transactions.

ARTICLE 12 INDEMNIFICATION 12.1 Indemnification of Buyer Parties. Subject to the terms and conditions of this Article 12, each of AWS and ATG agrees to indemnify and hold harmless the Buyer Parties and their successors and permitted assigns, the Company and their respective Affiliates, on an after-tax basis, against and in respect of any and all claims, demands, losses, damages, costs and reasonable expenses, including, without limitation, reasonable legal fees and expenses ("Damages"), resulting or arising from (a) any failure by any Seller Party to perform or otherwise fulfill or comply with any provision of this Agreement or any Related Agreement, and (b) any breach or violation of any representation or warranty of any Seller Party hereunder or under any Related Agreement (subject to Section 11.1). AWS agrees to indemnify and hold harmless the Buyer Parties and their successors and permitted assigns, the Company and their respective Affiliates, on an after-tax basis, against and in respect of any and all Damages resulting or arising from (x) any Taxes payable by the Company in respect of periods ending on or prior to the Closing Date and (y) the pending litigation described on Schedule 4.13. AWS shall be entitled to any recoveries whatsoever, including, but not limited to damages, attorneys' fees and costs obtained by or on behalf of the Company, in any order or judgment in or settlement of such litigation, whether pursuant to counterclaims asserted by the Company or otherwise. For greater certainty, the AWS Parties shall not be entitled to any contribution from Cantel in respect of any amount the AWS Parties are required to pay pursuant to this Section 12.1. 47 54 12.2 Indemnification of Seller Parties. Subject to the terms and conditions of this Article 12, each of the Buyer Parties agrees to indemnify and hold harmless the Seller Parties and their respective successors and permitted assigns and their respective Affiliates, on an after-tax basis, against and in respect of any and all Damages resulting or arising from any of the following, whether pursuant to a guarantee made to a Significant Party by a Seller or AWS or otherwise: (a) any failure by any Buyer Party to perform or otherwise fulfill or comply with any provision of this Agreement or any Related Agreement, (b) any breach or violation of any representation or warranty of a Buyer Party hereunder or under any Related Agreement and (c) all liabilities arising out of or relating to the Company (except for such matters as Sellers are required to indemnify the Buyer Parties pursuant to Section 12.1). 12.3 Claims. Any claim for indemnity under Section 12.1 or 12.2 shall be made by written notice from the party seeking to be indemnified (the "Indemnitee") to the party from which indemnification is sought (the "Indemnifying Party") specifying in reasonable detail the basis of the claim. When an Indemnitee seeking indemnification under Section 12.1 or 12.2 receives notice of any claims made by third parties ("Third Party Claims") which is to be the basis for a claim for indemnification hereunder, the Indemnitee shall give written notice within a reasonable period thereof to the Indemnifying Party reasonably indicating the nature of such claims and the basis thereof. Upon notice from the Indemnitee, the Indemnifying Party may, but shall not be required to, assume the defense of any such Third Party Claim, including its compromise or settlement, and the Indemnifying Party shall pay all reasonable costs and expenses thereof and shall be fully responsible for the outcome thereof, provided, however, that (i) the Indemnifying Party shall not settle any such claim without the Indemnitee's prior written consent (which consent shall not be unreasonably withheld) unless the only remedy for such claim is monetary damages which are paid in full by the Indemnifying Party and (ii) the Indemnifying Party shall not, without the written consent of the Indemnitee, settle or compromise any claim which does not include as an unconditional term thereof the giving by the claimant or the plaintiff to Indemnitee, a release from all liability in respect to such claim. In connection with any claim involving any remedy other than monetary damages, the Indemnitee shall have the right to be kept informed and be consulted in connection with the resolution of such claim. Other than with respect to claims listed on Schedule 4.13 the defense of which AWS has assumed, the Indemnifying Party shall give notice to the Indemnitee as to its intention to assume the defense of any such Third Party Claim within twenty (20) days after the date of receipt of the Indemnitee's notice in respect of such Third Party Claim. If an Indemnifying Party does not, within twenty (20) days after the Indemnitee's notice is given, give notice to the Indemnitee of its assumption of the defense of the Third Party Claim, the Indemnifying Party shall be deemed to have waived its rights to control the defense thereof. If the Indemnitee assumes the defense of any Third Party Claim because of the failure of the Indemnifying Party to do so in accordance with this Section 12.3, the Indemnifying Party shall pay all reasonable costs and expenses of such defense and shall be fully responsible for the outcome thereof. The Indemnifying Party shall have no liability with respect to any compromise or settlement thereof effected without its prior written consent, which consent shall not be unreasonably withheld. 48 55 12.4 Limitation of Liability. Each party to this Agreement shall have as its sole and exclusive remedy resulting from the breach of any representation or warranty made by the other party to this Agreement a claim for indemnity under Sections 12.1 or 12.2 of this Agreement. Any claims by any Buyer Party or any Seller Party for breach of any representation or warranty made hereunder shall be subject to the following: (a) with respect to Sections 12.1(b) and 12.2(b), the provisions for indemnity shall be effective only to the extent that the aggregate amount of all such claims for which a party is liable hereunder exceeds 0.50% of the Transaction Consideration, in which case the Buyer Party, ATG or AWS, as the case may be, shall be liable for all such amounts in excess thereof; provided, that in no event shall Buyer, ATG or AWS, as the case may be, be liable for more than an amount in the aggregate equal to 10.00% of the Transaction Consideration; provided, further, that the foregoing limitations shall not apply to the breach of any representation or warranty contained in Section 4.5 or Section 5.3; (b) In determining the amount of an indemnity on an after-tax basis, the amount of any claim for indemnity hereunder shall be reduced to reflect any actual tax savings received by the Indemnitee within three (3) years from the Closing Date that result from the liability that gave rise to such indemnity; and (c) the amount of any claim for indemnity hereunder shall be reduced to reflect any insurance proceeds recoverable by and paid to the Indemnitee relating to such claim, provided that the foregoing reduction shall not be applied if to do so would excuse any insurer from any obligation to cover any loss. 12.5 Manner of Payment. In the discretion of Buyer, up to 60% of the amount of any indemnification payment to be made hereunder by ATG or AWS may be made by reduction in the outstanding principal amount of the Notes.
