If within 30 days following the receipt of such notice by Seller any of such differences shall not have been resolved, such unresolved issues shall be referred to a nationally recognized firm of independent certified public accountants, mutually acceptable to the parties, for resolution, whose opinion thereon and the resulting actual Closing Working Capital shall be final, binding and not subject to any appeal. The fees and expenses of such public accounting firm shall be paid one-half by Purchaser and one-half by Seller. (c) On the applicable date referred to in Section 2.4(d), (i) if there is a Reconciliation Adjustment in Favor of Seller, Purchaser shall (x) pay to Seller a cash amount equal to 50% of the Reconciliation Adjustment in Favor of Seller and (y) deliver to the Seller a certificate evidencing such number of shares of AMSC Common Stock having, in aggregate, a Market Value on the Closing Date equal to 50% of the Reconciliation Adjustment in Favor of Seller; and (ii) if there is a Reconciliation Adjustment in Favor of Purchaser, Seller shall (i) pay to Purchaser a cash amount equal to 50% of the Reconciliation Adjustment in Favor of Purchaser and (y) deliver to the Purchaser a stock certificate endorsed in blank such number of shares of AMSC Common Stock having, in aggregate, a Market Value on the Closing Date equal to 50% of the Reconciliation Adjustment in Favor of Purchaser.

In the event that the Escrow Agent holds any cash at the time of the Final Payment, such payment to the Seller or such payment by the Seller, as applicable, shall instead be made to or by the Escrow Agent. Notwithstanding the foregoing, in the event that any issuance to Seller of shares of AMSC Common Stock under this Section 2.4 would, when taken together with the issuance to Seller of shares of AMSC Common Stock under Section 2.2, cause the number of such shares issued to Seller in the aggregate to exceed 19.95% of the total number of shares of AMSC Common Stock outstanding as of the date of the proposed issuance of shares under this Section 2.4(c) (including the shares to be so issued), AMSC shall deliver to Seller AMSC Warrants to purchase that number of shares of AMSC Common Stock equal to the difference between (i) the number of total shares which would be delivered pursuant to Section 2.2 and this Section 2.4 but for this sentence and (ii) that number of shares equal to 19.95% of the total number of shares of AMSC Common Stock outstanding as of the Closing Date.

All claims for ------------------------------- indemnification by a party entitled to be indemnified hereunder (an "Indemnitee") by another party hereto (an "Indemnitor"), except for claims relating to Taxes which shall be governed by the provisions of Article 8, shall be asserted and resolved as follows: (a) In the event that any claim or demand for which an Indemnitee may claim indemnity is asserted against or sought to be collected from an Indemnitee by a third party, the Indemnitee shall notify the Indemnitor within 20 days following the receipt by the Indemnitee of such claim or demand, specifying the nature of such claim or demand and the amount or the estimated amount thereof to the extent then feasible (which estimate shall not be conclusive of the final amount of such claim and demand) (the "Claim Notice"). Failure of an Indemnitee to so notify an Indemnitor within such 20-day period shall not relieve an Indemnitor of its obligation to indemnify the Indemnitee for such claim or demand except to the extent that the delay in giving notice of such claim or demand in fact materially prejudices (i) the defense of such claim or demand where the Indemnitor has the right to control such defense or (ii) participation in the defense of such claim or demand where the Indemnitor has a right of participation. Any party hereto against whom a claim or demand is asserted by a third party shall, without prejudice to any right of indemnification hereunder, appropriately respond to such claim or demand (whether by answer, denial, request for extension of time or other action) to such claim or demand within any applicable time period, so as to preserve any rights or remedies it or any other party may have against the person making such claim or demand. (b) An Indemnitor shall have thirty (30) days from the date on which the Claim Notice is duly given (the "Notice Period") to notify an Indemnitee (i) whether or not it disputes the liability of the Indemnitor to the Indemnitee hereunder with respect to such claim or demand and (ii) whether or not the Indemnitor desires, at its sole cost and expense, to defend the Indemnitee against such claim or demand. If an Indemnitor does not notify an Indemnitee within the Notice Period that it disputes its liability to the Indemnitee, the Indemnitor shall be liable for the amount of any resulting Losses. (c) In the event an Indemnitor notifies an Indemnitee within the Notice Period that it desires to defend the Indemnitee against such a claim against or demand from the Indemnitee, then except as hereinafter provided the Indemnitor shall defend, at its sole cost and expense, the Indemnitee by appropriate proceedings, shall use its best efforts to settle or prosecute such proceedings to a final conclusion in such a manner as to avoid any risk of the Indemnitee (or MAA, MAI or the Subsidiaries, if a Purchaser is the Indemnitee) becoming subject to any injunctive or other equitable order or relief or to liability for any other matter, and shall control the conduct of such defense; provided, however, that the Indemnitor shall not, without the prior written consent of the Indemnitee, consent to the entry of any judgment against the Indemnitee or enter into any settlement or compromise which does not include, as an unconditional term thereof, the giving by the claimant or plaintiff to the Indemnitee of a release, in form and substance reasonably satisfactory to the Indemnitee, from all liability in respect of such claim or litigation. If the Indemnitee desires to participate in, but not control, any such defense or settlement, it may do so at its sole cost and expense. (d) Prior to an Indemnitor's settling any claim or demand the defense of which it has assumed control, the Indemnitor shall obtain the Indemnitee's approval, confirmed in writing in accordance with the notice provisions hereof, which approval shall not be unreasonably withheld or delayed. If an Indemnitee notifies an Indemnitor of its disapproval of such settlement, the Indemnitee shall thereupon become liable, from and after the date of its disapproval, for the amount of any award, judgment, costs or expenses (including attorney fees) in excess of the proposed settlement amount and shall have the right to elect to control the defense of such claim at its sole cost and expense. (e) In the event an Indemnitee should have a claim against an Indemnitor hereunder which does not involve a claim or demand being asserted against or sought to be collected from the Indemnitee (or MAA, MAI or the Subsidiaries, if a Purchaser is the Indemnitee) by a third party, the Indemnitee shall promptly send a Claim Notice with respect to such claim to the Indemnitor. If the Indemnitor does not notify the Indemnitee within the Notice Period that it disputes such claim, the Indemnitor shall be liable for the amount of any resulting Losses. Section 7.6 Method of Payment. Any indemnification payment by ------------------ Purchaser to Seller pursuant to this Article 7 or Article 8 shall be made in immediately available funds. Any indemnification payment by Seller to Purchaser pursuant to this Article 7 or Article 8 shall be made (i) first, in AMSC Common Stock received by Seller pursuant to this Agreement, and (ii) second, to the extent such indemnification payment amount exceeds the aggregate Market Value of the AMSC Common Stock held by Seller, in immediately available funds; provided, however, that any indemnification payments by Seller to Purchaser with respect to any breach of the representations and warranties contained in Section 3.25 or pursuant to Section 8.7(i) shall be made in immediately available funds. For purposes of any indemnification payment made by Seller pursuant to the immediately preceding sentence, the Market Value of the AMSC Common Stock shall be calculated as the higher of (A) the Market Value as of the date hereof, and (B) the Market Value as of the date of such indemnification payment. Section 7.7 Limitation of Recourse. ---------------------- (a) Following the Closing, except with respect to claims based upon fraud, the indemnification provided by Article 7 or Article 8 shall be the sole and exclusive remedy for any Losses of any party hereto with respect to any misrepresentation or inaccuracy in, or breach of, any representations or warranties or any breach or failure in performance prior to Closing of any covenants or agreements made by any party in this Agreement or in any exhibit or schedules hereto or any certificate delivered hereunder. (b) No claim shall be brought or maintained by AMSC or Purchaser or their respective successors or permitted assigns against any officer, director or employee (present or former) of any of the Companies or Seller, or by Seller or its respective successors or permitted assigns against any officer, director or employee (present or former) of Purchaser or AMSC, and no recourse shall be brought or granted against any such persons, by virtue of or based upon any alleged misrepresentation or inaccuracy in or breach of any of the representations, warranties or covenants of any of the Companies or Seller on the one hand, or Purchaser or AMSC on the other hand, set forth or contained in this Agreement or any exhibit or schedule hereto or any certificate delivered hereunder, except to the extent that the same shall have been the result of fraud by any such Person (and in the event of such fraud, such recourse shall be brought or granted solely against the Person or Persons committing such fraud).

AMSC -------------------------------------------- hereby represents and warrants to Seller that: (a) Except for any transaction contemplated by this Agreement (e.g., an election under Section 338(h)(10) of the Code), AMSC shall cause the Companies not to engage in any transaction outside the ordinary course of business on the Closing Date after the Closing if such transaction would increase the tax liability of any of the Companies for any Taxable Year or portion thereof ending on the Closing Date. AMSC and Seller agree to treat any transaction of the Companies which is (i) - - outside the ordinary course of business and (ii) occurs on the Closing Date but after the Closing as occurring, for federal income Tax purposes, at the beginning of the day after the Closing Date, in accordance with Treasury Regulations Section 1.1502-76(b)(1)(ii)(B).

(c) To the knowledge of AMSC, following the Merger, MAA will hold at least 90 percent of the fair market value of Merger Sub's net assets and at least 70 percent of the fair market value of Merger Sub's gross assets held immediately prior to the Merger.

Except as provided in the next sentence, at any time during the eighteen (18) months following the Closing Date, if AMSC causes or permits MAA to issue additional shares of stock such that AMSC (or any permissible transferee thereof) loses control of MAA within the meaning of Section 368(c) of the Code, AMSC shall, prior to such issuance, provide an opinion of Arnold & Porter, or other counsel reasonably acceptable to Seller, that such issuance of additional shares will not cause the Merger to fail to qualify as a tax-free reorganization under Section 368(a)(2)(E) of the Code. The second sentence of this Section 8.2(f) shall not apply if, prior to such issuance of additional shares of MAA stock, Seller and its Affiliates do not own at least fifty percent (50%) of the AMSC Common Stock received by Seller in the Merger. (g) AMSC has no plan or intention (i) to liquidate MAA, (ii) to sell or otherwise dispose of the MAA Shares except for transfers of such shares to corporations controlled by AMSC, or (iii) to cause MAA to sell or otherwise dispose of any of its assets or of any of the assets acquired from Merger Sub, except for dispositions made in the ordinary course of business or transfers of assets to a corporation controlled by MAA within the meaning of Section 368(c) of the Code.

In addition to the Tax Returns that it is required to file under the immediately preceding sentence, Seller may, on or before the Closing Date, file any Tax Return of or including any Company for any Taxable Year (including any Short Taxable Year) that ends on or before the Closing Date. (b) (i) AMSC shall be responsible for the preparation and filing of all Tax Returns of the Companies that are due (including extensions) after the Closing Date, other than (A) Tax Returns that Seller is required to file under the first sentence of Section 8.3(a) and (B) Tax Returns that Seller has filed on or before the Closing Date pursuant to the second sentence of Section 8.3(a), provided, however, that AMSC shall have no obligation to prepare any Tax Return for any affiliated, consolidated, unitary or other group of which any Company is, was or will be a member prior to the Closing Date (other than any Tax Return that is due (including extensions) after the Closing Date for such a group that consists solely of two or more of the Companies). (ii) At the Closing, Seller shall provide AMSC with a list of all unfiled Tax Returns for or including any Company for Taxable Years ending on or before the Closing Date. (iii) If, pursuant to Section 8.7(a), Seller is liable to indemnify AMSC for any Taxes shown on a Tax Return that AMSC is required to file under Section 8.3(b)(i), AMSC shall use all commercially reasonable efforts to provide Seller with a copy of any such Tax Return (along with a computation of the amount of Tax shown on such Tax Return for which Seller is responsible) a reasonable time prior to the filing thereof. AMSC shall use all commercially reasonable efforts to provide any such income Tax Return at least sixty (60) days prior to the due date thereof. AMSC will consider any suggestion made by Seller with respect to the calculations and positions taken in such Tax Returns. Failure by AMSC to comply with the provisions of this Section 8.3(b)(iii) will in no way eliminate, limit or restrict Seller's indemnification obligations set forth in Section 8.7. (c) (i) Seller shall pay or cause to be paid (A) all Taxes of the Companies or Taxes for which any Company may be liable that are due on or before the Closing Date, and (B) the federal and State income Taxes of the Companies for any Taxable Year (including any Short Taxable Year) ending on or before the Closing Date. (ii) No later than 180 days following the Closing Date, AMSC shall provide to Seller a federal income Tax computation and related schedules and data for each Company having a Short Taxable Year ending on the Closing Date, which Tax computation shall be consistent with Tax Returns filed for prior Taxable Years and shall reflect the income, gain or loss of such Company for that Short Taxable Year other than any income, gain or loss arising or resulting from any election described in Section 8.4. (iii) Seller shall use all commercially reasonable efforts to complete prior to the Closing Date all necessary federal income Tax computations and related schedules and data for each Company for the Taxable Years of the Companies ending on December 31, 1997. To the extent necessary for Seller to complete such computations, schedules and data, AMSC shall allow Seller and its agents reasonable access after the Closing Date to the books and records of the Companies. (iv) Except as provided in Section 8.3(c)(i), AMSC shall pay or cause to be paid all Taxes of the Companies that are due after the Closing Date. (v) The provisions of this Section 8.3(c) shall not be construed or applied to limit or broaden the indemnification obligations of either Seller or AMSC under Section 8.7 except as specifically provided therein. All Tax Returns and computations referred to in this Article 8 shall be prepared in a manner consistent with prior Tax Returns, insofar as such Tax Returns and computations referred to in this Article 8 relate solely to the Companies. (d) AMSC and Seller shall use all commercially reasonable efforts to provide each other with copies of Tax Returns (including amended Tax Returns) of or including any Company to the extent any such Tax Returns are relevant in determining either party's obligations under this Agreement, including, but not limited to, the indemnification obligations in Section 8.7 and the procedural obligations in this Section 8.3. The provisions of this Section 8.3 shall not be construed or applied to limit or broaden the indemnification obligations of either Seller or AMSC under Section 8.7 except as specifically provided therein. (e) Seller and AMSC shall provide prior notice to, and cooperate fully with, each other in connection with any audit examinations of any Company by any governmental taxing authority with respect to any Taxes, including but not limited to the furnishing or making available of records, books of account or other materials reasonably necessary or helpful for the defense against the assertions of any taxing authority as to any Taxes or deficiencies thereof. (f) Seller and AMSC shall cooperate with one another and their respective representatives, in a prompt and timely manner, in connection with the preparation, signing, and filing of, and any administrative or judicial proceeding involving, any Tax Return filed or required to be filed by or for (i) the Seller Group, any member thereof, or any Company for any Taxable Year (including any Short Taxable Year) ending on or before the Closing Date, or (ii) the AMSC Group, any member thereof, or any Company for any Taxable Year (including any Short Taxable Year) ending after the Closing Date, with respect to any item or issue affecting the property or operations of any Company. Such cooperation shall include, but not be limited to, making available to the other party, during normal business hours, all books, records (including, but not limited to, working papers and schedules), information, officers and employees (without substantial interruption of employment) reasonably requested and necessary or useful in connection with any Tax inquiry, audit, investigation, dispute, litigation or any other matter requiring any such books, records, information, officers or employees for any reasonable business purpose. Notwithstanding the foregoing, neither party shall be required to furnish to the other Tax Returns or drafts thereof of the Seller Group, the AMSC Group, or any affiliated, consolidated, combined, unitary or other group of which any Company is, will be or was a member, as the case may be, for any Taxable Year, except that each party shall furnish to the other the applicable portions of such Tax Returns reporting the operations of the Companies and the applicable portions of all reports relating to the examination by the IRS or any other federal, State or local governmental agency. Any information obtained pursuant to this Article 8 shall be held in strict confidence and shall be used solely in connection with the reason for which it was requested. (g) As of the Closing Date, any and all Tax sharing or allocation agreements shall terminate as between any Company, on the one hand, and Seller or any Affiliates thereof, on the other hand, for all Taxes regardless of the Taxable Year for which such Taxes are imposed, and the provisions of this Agreement shall apply thereafter. (h) (i) AMSC shall not, and shall not permit any other person or entity to, dispose of or destroy any of the business records and files of any Company in existence on the Closing Date relating to Taxes without first offering to turn over possession thereof to Seller by written notice to Seller at least 30 days prior to the proposed date of such disposition or destruction. (ii) Seller shall not, and shall not permit any other person or entity to, dispose of or destroy any business records and files relating to Taxes of any Company now in the possession of, or subsequently acquired by, either Seller, any member of the Seller Group or any Affiliate of Seller without first offering to turn over possession thereof to AMSC by written notice to AMSC at least 30 days prior to the proposed date of such disposition or destruction. Section 8.4 Asset Purchase Treatment for MAI Shares. --------------------------------------- (a) (i) At the sole election of Purchaser, Purchaser and Seller shall elect for federal Tax purposes to treat the purchase and sale of the MAI Shares pursuant to this Agreement as a purchase and sale of the assets of MAI in accordance with the provisions of Code Section 338 generally and Code Section 338(h)(10) specifically. If an election is to be made as provided in the preceding sentence, Purchaser and Seller agree to make timely all elections necessary to carry out the provisions of this Section 8.4(a)(i) and to report the purchase and sale of the MAI Shares consistent with the preceding sentence and in accordance with the provisions of this Article 8. (ii) If Purchaser and Seller make the election in Section 8.4(a)(i), then Purchaser and Seller shall elect, for State income Tax purposes, to treat the purchase and sale of the MAI Shares as a purchase and sale of the assets of MAI to the extent permitted by applicable law. If an election is to be made as provided in the preceding sentence, Purchaser and Seller agree to make timely all elections necessary to carry out the provisions of this Section 8.4(a)(ii) and to report the purchase and sale of the MAI Shares consistent with the preceding sentence and in accordance with the provisions of this Article 8. In any State(s) where it is unclear whether applicable law permits the purchase and sale of the MAI Shares to be treated as a purchase and sale of assets, Purchaser and Seller agree to treat the purchase and sale of the MAI Shares as a purchase and sale of the assets of MAI provided that Seller and Purchaser otherwise make the election described in Section 8.4(a)(i). (iii) The provisions of Section 8.4(b), (c), (d) and (e) below shall apply if Seller and Purchaser make an election described in Section 8.4(a)(i) or (ii). (b) Seller shall pay or otherwise be liable for (and shall indemnify and hold harmless AMSC, its subsidiaries and the Companies against) any and all Taxes and Other Tax Costs attributable to the recognition of income by Seller or any Company (and Seller shall receive the tax benefit from any loss) from the treatment of the purchase and sale of the MAI Shares as a purchase and sale of the assets of MAI in accordance with the provisions of Section 8.4(a). (c) Purchaser and Seller hereby agree to determine the fair market value of the assets, both tangible and intangible, of MAI (and of any partnership Affiliates of MAI and MAA) (the "Assets") for purposes of allocating the consideration to be paid for, and the amount realized on the sale of, the Assets. This determination, which shall be binding upon Purchaser and Seller in accordance with the provisions of Section 1060(a) of the Code, shall be made as follows: (i) No later than sixty (60) days (or such later date as the parties mutually agree) following the Closing Date, Purchaser shall cause an appraiser (the "Appraiser"), which shall be reasonably acceptable to Seller, to provide to Purchaser and Seller an appraisal of the fair market valuations of the Assets (the "Appraisal"). For purposes of this Section 8.4(c), the "fair market value" of an Asset shall mean the amount a willing buyer would pay to a willing seller for the actual property in question (and not calculated based solely upon the replacement cost for such property) in an arm's length transaction where each party to the transaction has full knowledge of all relevant information concerning such property. (ii) Each of Seller and Purchaser may provide the Appraiser with such information as it believes will be useful to the Appraiser in preparing the Appraisal. Copies of any written materials provided to the Appraiser by either Seller or Purchaser shall simultaneously be provided to the other party. All oral communication with the Appraiser shall be made through Purchaser, which shall provide Seller with reasonable opportunities to speak and meet with the Appraiser to express any views Seller reasonably believes are pertinent to the preparation of the Appraisal. (iii) Purchaser shall pay the basic fee of the Appraiser as set at the time the Appraiser is initially engaged by Purchaser. To the extent that any additional fees, costs or expenses are incurred as a result of documents provided by Seller, communications initiated by Seller or meetings held at Seller's request, Seller shall pay such fees, costs or expenses. (iv) The fair market valuations of the Assets determined by the Appraiser pursuant to this Section 8.4(c) shall be the fair market valuations of the Assets for Tax purposes and shall be binding upon Seller and Purchaser as provided in this Agreement. (d) Neither Seller nor Purchaser nor any Affiliate of Seller or Purchaser shall take a position in any Tax proceeding, Tax audit or otherwise inconsistent with the fair market value determinations described in Section 8.4(c); provided, however, that (i) nothing contained herein shall require Seller or Purchaser to contest any challenge to such determinations, and (ii) nothing contained herein shall prevent Seller, Purchaser, or any of their Affiliates from filing protective amended Tax Returns or claims for refunds after a Tax authority has challenged such determinations. In the event that any claim shall be made by any taxing authority against either Purchaser or any Company (or any successor thereto), on the one hand, or Seller, on the other hand, that, if successful, would have the effect of altering such fair market value determinations, then the party that is the subject of such claim ("Involved Party") shall give notice thereof to the other party ("Other Party") in writing within 30 business days thereof. Thereafter, except as provided in the next sentence, the Involved Party shall have control of any contest relating thereto, but the Involved Party shall consider in good faith any request or suggestion by the Other Party for any conference, hearing or proceeding relating to such contest, shall (to the extent it is feasible to do so) permit the Other Party to participate therein at such Other Party's expense and shall not object to such Other Party's submission of briefs and memoranda of law relating thereto, and shall provide the Other Party with any relevant information reasonably requested by such Other Party. Notwithstanding the provisions of the preceding sentence, the Other Party shall have control of any contest relating to the fair market valuations if the Involved Party has notified the Other Party that the Other Party is obligated under the provisions of Section 8.7 to indemnify the Involved Party for any Tax liability relating to the proposed adjustments to the fair market valuations and the Other party shall have provided to the Involved Party the written notice and acknowledgment of financial responsibility referred to in the first sentence of Section 8.7(g). (e) Purchaser and Seller each agrees to prepare and file all Internal Revenue Service forms and the required schedules thereto and all requisite State and local forms and schedules ("Forms") required to be filed by either or both of them providing for the treatment of the purchase and sale of the MAI Shares as purchases and sales of the Assets in accordance with the provisions of Section 8.4(a). Purchaser shall request in writing from Seller, or Seller shall request in writing from Purchaser, any information (reasonably within the knowledge or possession of the person from whom requested) necessary to complete the Forms, which information shall be provided no later than 30 days following any such request. All such Forms shall be prepared consistent with the fair market valuations of the Assets determined under Section 8.4(c), provided, however, that Seller and Purchaser each recognize that appropriate adjustments will be made for transaction and other costs and as required by any applicable laws or regulations in determining the amount realized upon the disposition of the Assets or the amount paid for the Assets. Section 8.5 Tax-Free Reorganization Treatment for the MAA Merger. ---------------------------------------------------- Seller and AMSC agree that they intend that the Merger qualify as a tax-free reorganization described in Section 368(a)(2)(E) of the Code, and Seller and AMSC shall file all Tax Returns in a manner consistent with such treatment (including satisfying all reporting requirements necessary to obtain such treatment). Neither Seller nor AMSC nor any Affiliate of Seller or AMSC shall take a position in any Tax proceeding, Tax audit or otherwise inconsistent with the treatment of the Merger as a tax-free reorganization qualifying under Section 368(a)(2)(E) of the Code; provided, however, that nothing contained herein shall prevent Seller, AMSC, or any of their Affiliates from filing protective amended Tax Returns or claims for refund after a Tax authority has challenged such treatment. Section 8.6 Transfer Taxes. Notwithstanding any other provision -------------- in this Agreement, Seller and AMSC shall each be responsible for and pay one-half of any transfer taxes, recording taxes, bulk sale taxes and similar transaction taxes resulting from the transfer of the MAI Shares, the MAA Shares or the deemed transfer of the equity interests in or the assets of any Company as a result of the transactions contemplated by this Agreement. Each party hereto hereby shall pay all such taxes and file all necessary documentation as required under the applicable statutory provisions with respect to all such taxes in a timely manner. Not later than fifteen (15) business days following receipt of written notice from AMSC or Seller that it has paid any Taxes described in this Section 8.6, the other party shall pay to the payor its one-half share of such Taxes. Section 8.7 General Tax Indemnifications. ---------------------------- (a) Seller shall indemnify and hold harmless AMSC and its Affiliates (including the Companies) from and against any and all Taxes with respect to which any Company or any entity as successor thereto may be liable to the extent such Taxes are (i) attributable to any breach of any of Seller's representations, warranties or covenants contained in this Article 8, (ii) payable with respect to any Taxable Year ending on or prior to the Closing Date, or (iii) payable with respect to that portion of any Split Period that is prior to and including the Closing Date. Seller shall also indemnify and hold harmless AMSC and its Affiliates (including the Companies) from and against (iv) any and all Other Tax Costs relating to any Taxes described in this Section 8.7(a), and (v) any and all Taxes and Other Tax Costs arising in any Taxable Year ending after the Closing Date that result from any adjustment to any Tax Return of or including the Company for any Taxable Year ending on or before the Closing Date, provided, however, that the indemnification pursuant to this Section 8.7(a)(v) shall not apply to the extent that such adjustment relates to whether any asset is depreciable or amortizable, and further provided that any Tax or Other Tax Cost indemnifiable under any other provision of this Article 8 shall not be indemnifiable a second time under this Section 8.7(a)(v), and further provided that any indemnification pursuant to this Section 8.7(a)(v) shall not apply to any adjustment involving any agreement with a tax authority unless it has a Material Adverse Effect on any Company (or any successor thereto). Notwithstanding the preceding, Seller shall not be obligated to indemnify AMSC or any of its Affiliates (including the Companies) for, in the case of taxes described in clauses (ii), (iii), (iv) and (v), any Taxes that result from AMSC's breach of any representation or warranty contained in this Article 8. (b) AMSC shall indemnify and hold harmless Seller and its Affiliates from and against any and all Taxes with respect to which Seller, any of Seller's Affiliates, any Company or any entity as successor thereto may be liable to the extent such Taxes are (i) attributable to any breach of any of AMSC's representations or warranties contained in this Article 8, (ii) insofar as they relate to any Company or any entity as successor thereto, payable with respect to any Taxable Year beginning and ending after the Closing Date, or (iii) insofar as they relate to any Company or any entity as successor thereto, payable with respect to that portion of any Split Period that begins after the Closing Date. AMSC shall also indemnify and hold harmless Seller and its Affiliates from and against (iv) any and all Other Tax Costs relating to any Taxes described in this Section 8.7(b). Notwithstanding the preceding, AMSC shall not be obligated to indemnify Seller or any of its Affiliates for, in the case of taxes described in clauses (ii), (iii) and (iv), any Taxes that result from Seller's breach of any representation or warranty contained in this Article 8. For purposes of this Section 8.7(b), if AMSC's obligation to indemnify for Taxes arises as a result of the Merger failing to qualify as a reorganization under Section 368(a) of the Code, such obligation shall be limited to an amount that reflects the value of the timing difference between (x) the year in which such Taxes are actually payable and (y) the year or years in which Seller disposes of the AMSC Common Stock received by Seller in the merger, adjusted to take into account any Tax benefit Seller may realize from the early payment. (c) If the Seller's indemnification obligation under this section 8.7 arises in respect of any adjustment (i) for which AMSC or any of its Affiliates (including any of the Companies) receives indemnification from the Seller and (ii) which results in any Tax benefit to AMSC or any Affiliate of AMSC (including any of the Companies) thereof for any Taxable Year or Split Period beginning after the Closing Date which would not, but for such adjustment, be available, AMSC shall pay, or shall cause to be paid, to the Seller an amount equal to the actual Tax saving produced by such Tax benefit at the time such Tax saving is realized by AMSC or any of its Affiliates (including any of the Companies). The amount of any such Tax saving for any Taxable period shall be the amount of the reduction in Taxes payable to a taxing authority by AMSC or any of its Affiliates (including any of the Companies) thereof with respect to such Taxable Year or Split Period as compared to the Taxes that would have been payable to a taxing authority by AMSC or any of its Affiliates (including any of the Companies) with respect to such Taxable Year or Split Period in the absence of such Tax benefit. (d) For purposes of this Section 8.7, in the case of any Taxes that are payable with respect to a Split Period, the portion of such Taxes allocable to Seller or to the portion of the Split Period ending on the Closing Date shall be equal to (i) in the case of Taxes imposed on the basis of income or receipts, an amount determined on the basis of a closing of the books as of the end of the Closing Date and (ii) in the case of any other Taxes, the product of the total Taxes for the period multiplied by a fraction the numerator of which is the number of days in the Split Period from the commencement of the Split Period through and including the Closing Date and the denominator of which is the number of days in the entire Split Period (provided, however, that for purposes of this clause (ii) appropriate adjustments shall be made to reflect specific events that can be identified and specifically allocated as occurring on or prior to the Closing Date (in which case Seller shall be responsible for any Taxes related thereto) or occurring after the Closing Date (in which case AMSC shall be responsible for any Taxes related thereto)). Notwithstanding any other provision in this Section 8.7(d), Section 8.2(a) or any other provision in this Agreement, any income, gain, gross receipts, net receipts or similar Tax item recognized by any Company as a result of any transaction described in Section 5.17 shall be treated as recognized by such Company for all Tax purposes exclusively in (x) Taxable Years ending on or prior to the Closing Date, and/or (y) those portions of Split Periods that are prior to and including the Closing Date. (e) Seller or AMSC, as the case may be (the "Tax Indemnitee"), shall notify the other party (the "Tax Indemnitor") in writing in a reasonably prompt fashion of any written inquiries, notices of audit, assertions of liability, or other written communications from or with a Tax authority that relate to Taxes with respect to which the Tax Indemnitor may be liable under this Article 8 (a "Tax Claim"). Failure by the Tax Indemnitee to notify the Tax Indemnitor as required by this Sectio 8.7(e) shall not relieve the Tax Indemnitor of its liability and obligation to indemnify the Tax Indemnitee under this Agreement unless such failure precludes the Tax Indemnitor from contesting the Taxes giving rise to its indemnification obligation and there is at least a reasonable possibility that the Tax Indemnitor would have prevailed in challenging such Taxes. (f) Seller and AMSC shall take all reasonable steps and actions necessary or appropriate to minimize any indemnification obligations either party may have under this Section 8.7. (g) Except as provided in the next sentence, within thirty (30) days of receiving notice of a Tax Claim, the Tax Indemnitor, at its sole cost and expense, may elect, by written notice to the Tax Indemnitee, to assume sole responsibility for defending such Tax Claim, but only if, in such written notice to the Tax Indemnitee, the Tax Indemnitor acknowledges full and complete financial responsibility for all Taxes covered by such Tax Claim and all Other Tax Costs related thereto. Notwithstanding the provisions of the preceding sentence, Seller shall not have the rights to settle or litigate any Tax Claim, or to control and determine the timing and amount of any payment or deposit of an amount relating to any Tax Claim, the submission or content of documentation, returns or other Tax forms, protests, memoranda of law and briefs, the conduct of oral arguments or presentations, the selection of witnesses and the negotiation of stipulations of fact with respect to any Taxable Year ending after the Closing Date. If the Tax Indemnitor assumes responsibility for defending a Tax Claim pursuant to this Section 8.7(g), it shall keep the Tax Indemnitee reasonably informed of the status of such Tax Claim, and the Tax Indemnitee and its representatives shall be entitled to attend any meetings or hearings involving the Tax Claim at its own expense. If the Tax Indemnitor does not elect to assume control of defending any Tax Claim, the Tax Indemnitee may settle or defend such Tax Claim. In such a case, if the Tax Indemnitor is responsible for the asserted Taxes under this Article 8, the Tax Indemnitor shall indemnify the Tax Indemnitee for the reasonable cost of its defense, in addition to the underlying Taxes. (h) Any unresolved dispute relating to any payments or indemnification obligations of either Seller or AMSC to the other pursuant to the provisions of this Article 8 shall be submitted to an arbitrator mutually acceptable to Seller and AMSC (or, if the parties are unable to agree upon an arbitrator, to an arbitrator selected by the American Arbitration Association). Any such arbitration shall be conducted in accordance with the rules of the American Arbitration Association in effect at the time of the arbitration. Where any dispute relates to a position to be taken on any Tax Return of or including a Company, the parties shall use reasonable efforts to resolve the dispute informally or pursuant to arbitration prior to filing such Tax Return. In the event the parties are unable to resolve any dispute prior to filing a Tax Return, the position taken on the Tax Return shall have no impact or influence on the resolution of the underlying dispute, and in no way shall prejudice either party's rights or obligations under this Article 8, nor shall any resolution of any dispute have any impact on how a Tax Return must be filed. In the event an indemnification dispute arises that is based on a disagreement as to how a Tax Return of or including a Company should be filed, the indemnification obligations of the indemnifying party under this Section 8.7 shall be determined consistent with the filing position advanced by such party if such position is not inconsistent with prior Tax Returns and accounting conventions and is proper and legal. If a Tax authority subsequently determines that the position advanced by the indemnifying party is incorrect, the indemnifying party's obligation to indemnify the other party shall be determined consistent with the determination of the Tax authority. (i) Notwithstanding Section 8.7(b), AMSC shall not be responsible for, and Seller shall indemnify and hold harmless AMSC and its Affiliates (including the Companies) from and against any and all Taxes or Other Tax Costs with respect to which any Company or any entity as successor thereto may be liable to the extent such Taxes arise in any Taxable Year ending after Closing Date that result from any income, net receipts, gross receipts, gain or similar items recognized by any Company as a result of the transactions contemplated in Section 5.16. (j) AMSC and Seller agree to cooperate in good faith in carrying out the provisions of this Article 8. (k) This Article 8 shall be construed and applied to avoid any double counting of any payments, credits or other benefits with respect to any representation, warranty, covenant or indemnity set forth herein. Section 8.8 Exclusive Remedy for Taxes. Except as provided in -------------------------- Section 7.3, this Article 8 provides the exclusive agreement between Seller, AMSC and their respective Affiliates regarding responsibility for the Taxes of the Companies. Section 8.9 Survival and Purchase Price Adjustment. -------------------------------------- (a) Notwithstanding any other provision of this Agreement, the covenants, promises, indemnifications and other obligations of the parties hereto set forth in this Article 8 shall survive the Closing until fully carried out and the expiration of any applicable statute of limitations relating to the Taxes covered thereby. (b) In the event any payments are made to Seller pursuant to the provisions of this Article 8, such payments are adjustments to the purchase price paid for the MAI Shares as set forth in Section 2.2(B).

In the event that a termination occurs pursuant to this Section 9.2: (a) the Escrow Agent shall return the MAI Purchase Price to the Purchaser; (b) Purchaser shall return the Shares to Seller; (c) Seller shall return to Purchaser the AMSC Common Stock issued to Seller for the MAA Shares pursuant to the terms of Section 2.1(a); and (d) each parties shall have only those rights and obligations held by such party prior to the Closing Date.

The Company shall pay any and all documentary, stamp or similar issue or transfer taxes payable in respect of the issue or delivery of this Warrant and the issue and delivery of the Warrant Shares. C. If the Holder exercises this Warrant in part, this Warrant shall be surrendered by the Holder to the Company and a new Warrant of the same tenor and for the unexercised number of Warrant Shares shall be executed by the Company. The Company shall register the new Warrant in the name of the Holder or in such name or names of its transferee(s) pursuant to Section 8 hereof as may be directed in writing by the Holder and deliver the new Warrant to the Person or Persons entitled to receive the same. D. Except as otherwise provided in Section 3, upon surrender of this Warrant in conformity with the foregoing provisions, the Company shall transfer to the Holder of this Warrant appropriate evidence of ownership of the shares of Common Stock or other securities or property (including any money) to which the Holder is entitled, registered or otherwise placed in, or payable to the order of, the name or names of the Holder or its transferee(s) as may be directed in writing by the Holder, and shall deliver such evidence of ownership and any other securities or property (including any money) to the Person or Persons entitled to receive the same, together with an amount in cash in lieu of any fraction of a share as provided in Section 7 below. 3. OWNERSHIP LIMITATION. If at any time the exercise of any Warrants pursuant to Section 2 would cause the Company's Alien Ownership Percentage to exceed the Accepted Alien Ownership Percentage Limitation, then in lieu of issuing shares of Common Stock pursuant to Section 2: A. the Company shall issue to each Holder exercising Warrants at such time (each an "Exercising Holder") whose Alien ------------------ Ownership Percentage is less than or equal to the Accepted Alien Ownership Percentage Limitation the number of shares of Common Stock to which such Exercising Holder is entitled pursuant to Section 2; B. the Company shall issue to each Exercising Holder whose Alien Ownership Percentage is greater than the Accepted Alien Ownership Percentage Limitation (each, an "Affected Exercising Holder") a number of shares of Common Stock equal to the quotient of (x) the product of (A) the number of shares of Common Stock that, immediately after giving effect to any issuances of Common Stock pursuant to the foregoing Section 3.A, could be issued to a Person with a 100% Alien Ownership Percentage without causing the Company's Alien Ownership Percentage to exceed the Accepted Alien Ownership Percentage Limitation, multiplied by (B) the number of shares of Common Stock to which such Affected Exercising Holder would be entitled pursuant to Section 2 but for the application of this Section 3, divided by (y) the product of (A) the aggregate number of shares of Common Stock to which all Affected Exercising Holders would be entitled pursuant to Section 2 but for the application o this Section 3, multiplied by (B) such Affected Exercising Holder's Alien Ownership Percentage; provided that in no event shall the number of shares of Common Stock issuable to any Affected Exercising Holder pursuant to this Section 3.B exceed the number of shares of Common Stock to which such Affected Exercising Holder would have been entitled pursuant to Section 2 but for the application of this Section 3; and C. the Company shall deliver by wire transfer of immediately available funds to the account of each Affected Exercising Holder specified in such Affected Exercising Holder's Warrant Exercise Notice, an amount equal to the product of (x) the number of shares of Common Stock to which such Affected Exercising Holder would have been entitled pursuant to Section 2 that are not issuable to such Affected Exercising Holder pursuant to the foregoing Section 3.B, multiplied by (y) the Warrant Margin on the Exercise Date. 4. RESTRICTIVE LEGEND. Upon original issuance thereof, and until such time at the same shall have been registered under the Securities Act or sold pursuant to Rule 144 promulgated thereunder (or any similar rule or regulation), each Warrant and any certificates evidencing Warrant Shares shall bear a legend substantially in the form of the legend set forth on the first page hereof, unless in the opinion of counsel reasonably satisfactory to the Company, such legend is no longer required by the Securities Act. 5. RESERVATION OF SHARES. The Company hereby agrees that at all times it shall reserve for issuance and delivery upon exercise of this Warrant such number of its authorized but unissued shares of Common Stock as will be sufficient to permit the exercise in full of this Warrant. All such shares shall be duly authorized and, when issued upon such exercise, shall be validly issued, fully paid and non-assessable, free and clear of all liens, security interests, charges and other encumbrances or restrictions on sale (other than general regulatory restrictions under the Communications Act) and free and clear of all preemptive rights. 6. FRACTIONAL SHARES. No fractional shares or scrip representing fractional shares shall be issued upon the exercise of this Warrant and in lieu of delivery of any such fractional share upon any exercise hereof, the Company shall pay to the Holder an amount in cash equal to such fraction multiplied by the Current Market Price Per Common Share on the Exercise Date. 7. EXCHANGE, TRANSFER OR ASSIGNMENT OF WARRANT. A. The Company shall from time to time register the exchange or transfer of any outstanding Warrant in a Warrant register to be maintained by the Company upon surrender thereof accompanied by a written instrument or instruments of transfer in form satisfactory to the Company, duly executed by the registered Holder or Holders thereof or by the duly appointed legal representative thereof or by a duly authorized attorney. Each taker and holder of this Warrant by taking or holding the same, consents and agrees that the registered holder hereof may be treated by the Company and all other Persons dealing with this Warrant as the absolute owner hereof for any purpose and as the Person entitled to exercise the rights represented hereby. B. Prior to any proposed transfer of the Warrants or the Warrant Shares, unless such transfer is made pursuant to an effective registration statement under the Securities Act the Holder will deliver to the Company, if so requested by the Company, an opinion of counsel reasonably satisfactory in form and substance to the Company, to the effect that the Warrants or Warrant Shares, as applicable, may be sold or otherwise transferred without registration under the Securities Act. Subject to the preceding sentence, the Holder of this Warrant shall be entitled, without obtaining the consent of the Company, to assign and transfer this Warrant, at any time in whole or from time to time in part, to any Person or Persons. Subject to the foregoing, upon surrender of this Warrant to the Company, together with the attached Warrant Assignment Form duly executed, the Company shall, without charge, execute and deliver a new Warrant in the name of the assignee or assignees named in such instrument of assignment and, if the Holder's entire interest is not being assigned, in the name of the Holder, and this Warrant shall promptly be cancelled. 8. LOSS OR DESTRUCTION OF WARRANT. Upon receipt by the Company of evidence satisfactory to it (in the exercise of its reasonable discretion) of the loss, theft, destruction or mutilation of this Warrant, and (if requested by the Company in the case of loss, theft or destruction) of reasonably satisfactory indemnification, and upon surrender and cancellation of this Warrant, if mutilated, the Company shall execute and deliver a new Warrant of like tenor and date representing the right to purchase an equivalent number of Warrant Shares. 9. ANTI-DILUTION PROVISIONS. A. In case the Company shall at any time after the date hereof (i) declare a dividend or make a distribution on Common Stock payable in Common Stock or other shares of the Company's capital stock, (ii) subdivide, split or reclassify the outstanding Common Stock into a larger number of shares, (iii) combine or reclassify the outstanding Common Stock into a smaller number of shares, or (iv) issue any shares of its capital stock in a reclassification of Common Stock (including any such reclassification in connection with a consolidation or merger in which the Company is the continuing corporation), then in each such case the Warrant Share Amount shall be adjusted to equal the number of shares to which the holder of this Warrant would have been entitled upon the occurrence of such event if this Warrant had been exercised immediately prior to such time. Such adjustment shall be made successively whenever any event listed above shall occur. B. In case the Company shall fix a record date for the making of a distribution to holders of Common Stock (including any such distribution made in connection with a consolidation or merger in which the Company is the continuing corporation) of evidences of indebtedness, assets or other property (excluding cash dividends, other cash distributions from current or retained earnings or dividends payable in Common Stock for which an adjustment has been made pursuant to Section 9.A), the Warrant Share Amount to be in effect after such record date shall be determined by multiplying the Warrant Share Amount in effect immediately prior to such record date by a fraction, the numerator of which shall be the Current Market Price Per Common Share, and the denominator of which shall be such Current Market Price Per Common Share on such record date, less the fair market value (determined by the Board of Directors of the Company; provided that if the Holder shall object to any such determination, the Board of Directors shall retain an independent appraiser reasonably satisfactory to the Holder to determine such fair market value) of the portion of the assets, other property or evidence of indebtedness so to be distributed which is applicable to one share of Common Stock. Such adjustments shall be made successively whenever such a record date is fixed; and in the event that such distribution is not so made, the Warrant Share Amount shall again be adjusted to be the Warrant Share Amount which would then be in effect if such record date had not been fixed. C. If as a result of any event or for any other reason, any adjustment is made which increases the number of shares of Common Stock issuable upon conversion, exercise or exchange of, or in the conversion or exercise price or exchange ratio applicable to, any outstanding securities of the Company that are convertible into, or exercisable or exchangeable for, Common Stock of the Company, then a corresponding adjustment shall be made hereunder to increase the Warrant Share Amount, but only to the extent that no such adjustment has been made pursuant to Section 9.A or B hereof with respect to such event or for such other reason. D. For the purpose of any computation under Section 3 or Section 9.B hereof, on any determination date the "Current Market -------------- Price Per Common Share" shall be deemed to be the average ------------------------- (weighted by daily trading volume) of the Closing Prices (as defined below) per share of Common Stock for the 20 consecutive trading days immediately prior to such date. "Closing Price" means (1) if shares of Common Stock then are listed and traded on the NYSE, the closing price on such day as reported, on the NYSE Composite Transactions Tape; (2) if shares of Common Stock then are not listed and traded on the NYSE, the closing price on such day as reported by the principal national securities exchange on which the shares are listed and traded; (3) if shares of Common Stock then are not listed and traded on any such securities exchange, the last reported sale price on such day on the NASDAQ; or (4) if shares of Common Stock then are not traded on the NASDAQ National Market, the average of the highest reported bid and lowest reported asked price on such day as reported by NASDAQ. If on any determination date shares of Common Stock are not quoted by any such organization, the Current Market Price Per Common Share shall be the fair market value of such shares on such determination date as reasonably determined by the Board of Directors. If the Holder shall object to any determination by the Board of Directors of the Current Market Price Per Common Share, the Current Market Price Per Common Share shall be the fair market value per share of Common Stock as determined by an independent appraiser retained by the Company at its expense and reasonably acceptable to the Holder. For purposes of any computation under this Section 9, the number of shares of Common Stock outstanding at any given time shall not include shares owned or held by or for the account of the Company. E. No adjustment in the Warrant Share Amount or the Exercise Price shall be required unless such adjustment would require an increase or decrease of at least one percent of such amount; provided that any adjustments which by reason of this Section 9.F are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Section 9 shall be made to the nearest one tenth of a cent or to the nearest hundredth of a share as the case may be. G. In the event that, at any time as a result of the provisions of this Section 9, the holder of this Warrant upon subsequent exercise shall become entitled to receive any shares of capital stock of the Company other than Common Stock, the number of such other shares so receivable upon exercise of this Warrant shall thereafter be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions contained herein. H. Upon any adjustment pursuant to this Section 9, the Company shall promptly thereafter (i) cause to be filed with the Company a certificate of an officer of the Company setting forth the Warrant Share Amount and Exercise Price after such adjustment and setting forth in reasonable detail the method of calculation and the facts upon which such calculations are based, and (ii) cause to be given to each registered Holder of this Warrant at the address as set forth in Section 11 written notice of such adjustments. Where appropriate, such notice may be given in advance and included as a part of the notice required to be delivered pursuant to Section 12.B. 10. REORGANIZATION, CONSOLIDATION, MERGER, OR SALE OF ASSETS. In case of any reclassification, redesignation, reorganization of recapitalization by the Company (other than as set forth in Section 9) or consolidation of the Company with, or merger of the Company into, any other Person, any merger of another Person into the Company (other than a merger which does not result in any reclassification, conversion, exchange or cancellation of outstanding shares of Common Stock) or any sale or transfer of all substantially all of the assets of the Company or of the Person formed by such consolidation or resulting from such merger or which acquires such assets, as the case may be, the Holder shall have the right thereafter to exercise this Warrant for the kind and amount of securities, cash and other property receivable upon such reclassification, redesignation, reorganization, recapitalization, consolidation, merger, sale or transfer by a holder of the number of shares of Common Stock for which this Warrant may have been exercised in full immediately prior to such reclassification, redesignation, reorganization, recapitalization, consolidation, merger, sale or transfer, assuming (i) such holder of Common Stock is not a Person with which the Company consolidated or into which the Company merged or which merged into the Company or to which such sale or transfer was made, as the case may be ("Constituent Person"), or an Affiliate of a Constituent Person and (ii) in the case of a consolidation, merger, sale or transfer which includes an election as to the consideration to be received by the holders, such holder of Common Stock failed to exercise its rights of election, as to the kind or amount of securities, cash and other property receivable upon such consolidation, merger, sale or transfer (provided that if the kind or amount of securities, cash and other property receivable upon such consolidation, merger, sale or transfer is not the same for each share of Common Stock held immediately prior to such consolidation, merger, sale or transfer by other than a Constituent Person or an Affiliate thereof and in respect of which such rights of election shall not have been exercised ("Non-electing share"), then for the purpose of this Section 10 the kind and amount of securities, cash and other property receivable upon such consolidation, merger, sale or transfer by each Non-electing share shall be deemed to be the kind and amount so receivable per share by a plurality of the Non-electing shares. Adjustments for events subsequent to the effective date of such reclassification, redesignation, reorganization, recapitalization, consolidation, merger and sale of assets shall be as nearly equivalent as may be practicable to the adjustments provided for in this Warrant. In any such event, effective provisions shall be made in the certificate or articles of incorporation of the resulting or surviving corporation, in any contract of sale, conveyance, lease or transfer, or otherwise so that the provision set forth herein for the protection of the rights of the Holder shall thereafter continue to be applicable; and any such resulting or surviving corporation shall expressly assume the obligation to deliver, upon exercise, such shares of stock, other securities, cash and property. The provisions of this Section 11 shall similarly apply to successive consolidations, mergers, sales, leases or transfers. 11. NOTICES.
