(b) From and after the Distribution Date, Gholdco shall prepare and timely file or cause to be timely filed (i) all Covered Group Returns and (ii) any Tax Returns that relate solely to the Generico Business (including all Income Tax Returns with respect to one or more members of the Generico Group that do not include any members of the Alpha Group).

6

(c) From and after the Distribution Date, New Alpha shall prepare and timely file or cause to be timely filed any Tax Returns that relate solely to the Alpha Business (including all Income Tax Returns with respect to one or more members of the Alpha Group that do not include any members of the Generico Group).

(d) All Covered Group Returns and all other Tax Returns relating to (i) any member of the Generico Group for Taxable years or periods ending on or before or including the Distribution Date and (ii) any member of the Alpha Group that are required to be filed by Gholdco pursuant to this Agreement, shall (to the extent permitted by Applicable Laws) be prepared on a basis consistent with the elections, methods of accounting, positions, conventions and principles of taxation and the manner in which any Tax item or other information is reported as reflected in comparable Tax Returns filed before the date of this Agreement, provided that a different method can be used (x) if it would not materially increase Taxes for which the Alpha Group would be responsible under this Agreement or (y) with the prior written consent of New Alpha (such consent not to be unreasonably withheld). The preceding sentence shall not apply to the extent (i) otherwise contemplated or required by the Ruling Request or Private Letter Ruling, or (ii) necessary to comply with any change in Applicable Laws. Consent shall not be considered unreasonably withheld within the meaning of the second preceding sentence if such different method would increase Taxes for which the Alpha Parties would be responsible under this Agreement and for which Gholdco does not compensate the Alpha Parties. Gholdco shall (A) make available to New Alpha any Tax Return it is responsible for filing pursuant to Section 2.01(a) at least 30 calendar days prior to filing, provided that New Alpha shall supply Gholdco with all information regarding any member of the Alpha Group necessary for preparing such Return at least 90 calendar days prior to the due date (taking into account any available extensions) for filing such Return, and (B) make reasonable revisions to any such Tax Return that are requested by New Alpha.

(e) Gholdco, New Alpha, or Alpha, as the case may be, shall bear 100% of out-of-pocket costs, including accountants’ and attorneys’ fees, incurred in preparing any Tax Returns it is responsible for preparing and filing under Section 2.01.

SECTION 2.02. Obligation to Remit Taxes. Gholdco and New Alpha shall each timely remit or cause to be timely remitted any Taxes due in respect of any Tax Return it is required to file or cause to be filed pursuant to Section 2.01.

(a) From and after the Distribution Date, the Alpha Parties shall indemnify, defend, and hold harmless the Generico Indemnified Parties from and against, any and all Indemnifiable Losses incurred or suffered by one or more of the Generico Indemnified Parties in connection with, relating to, arising out of, or due to, directly or indirectly, (i) any Alpha Taxes (including, for the avoidance of doubt, any Alpha Taxes arising from a redetermination thereof from an audit or examination of a Pre-Distribution Period or Straddle Period);

7

and (ii) any amount for which New Alpha is liable under Section 2.04. Any amount payable by the Alpha Parties to the Generico Parties with respect to any Tax pursuant to this Section 2.03(a) shall be reduced by any direct or indirect payments made by the Alpha Parties or any Alpha Affiliate with respect to such Tax after the Distribution Date to any Generico Indemnified Party and by any Prior Payments made by or on behalf of the Alpha Parties. The portion of a Prior Payment that is deemed to be on behalf of the Alpha Parties shall be the portion which bears the same proportion to the Prior Payment as the portion of Covered Group Taxes to which the Prior Payment relates that constitute Alpha Taxes bears to the amount of Covered Group Taxes to which the Prior Payment relates for the taxable year. As an example, if the amount of notional Taxes that constitute Alpha Taxes for the period beginning on January 1, 2007 and ending on the Distribution Date was $20X and the amount of notional Taxes that constitute Generico Taxes for the same period was $30X, then 40 percent of any estimated Tax payments made with respect to that period shall be deemed to have been made on behalf of the Alpha Parties.

(b) From and after the Distribution Date, the Generico Parties shall indemnify, defend, and hold harmless the Alpha Indemnified Parties from and against, any and all Indemnifiable Losses incurred or suffered by one or more of the Alpha Indemnified Parties in connection with, relating to, arising out of, or due to, directly or indirectly, (i) any Generico Taxes (including, for the avoidance of doubt, any Generico Taxes arising from a redetermination thereof from an audit or examination of a Pre-Distribution Period or Straddle Period); and (ii) any amount for which Gholdco is liable under Section 2.04. Any amount payable by the Generico Parties to the Alpha Parties with respect to any Tax pursuant to this Section 2.03(b) shall be reduced by any direct or indirect payments made by the Generico Parties or any Generico Affiliate with respect to such Tax after the Distribution Date to any Alpha Indemnified Party and by any Prior Payments made on behalf of the Generico Parties. The portion of a Prior Payment that is deemed to be on behalf of the Generico Parties shall be the portion which bears the same proportion to the Prior Payment as the portion of Covered Group Taxes to which the Prior Payment relates that constitute Generico Taxes bears to the amount of Covered Group Taxes to which the Prior Payment relates for the taxable year.

(c) Any and all prior Tax sharing agreements or practices between the Generico Parties or any Gholdco Subsidiary, on the one hand, and the Alpha Parties or any Alpha Subsidiary, on the other hand, shall automatically be terminated as of the Distribution Date (other than any such agreements set forth in the Transaction Agreements).

(d) From and after the Distribution Date, New Alpha shall be entitled to any refund of or credit for Alpha Taxes, provided that the Generico Parties shall be entitled to receive and retain any refund of Taxes to the extent such refund is attributable to a Tax Carryover Attribute relating to the Generico Business. From and after the Distribution Date, Gholdco shall be entitled to any refund of or credit for Generico Taxes.

SECTION 2.04. Restructuring Taxes; Other Taxes Relating to the Share Distribution.

(a) Except as otherwise provided in Section 4.02(c) and in the next sentence of this Section 2.04(a), the Alpha Parties shall be liable for 100% of any Restructuring Taxes. The Generico Parties shall be liable for any Restructuring Taxes that are imposed as a result of a Generico Tainting Act.

(b) Notwithstanding Section 2.04(a), the Generico Parties shall be liable for 50% and the Alpha Parties shall be liable for 50% of any sales, transfer, value added or other similar Taxes or fees (including all real estate, transfer Taxes, real estate recording fees, patent, copyright, and trademark recording fees and similar items relating to patents, copyrights and trademarks, but excluding Restructuring Taxes) payable in connection with the transactions contemplated by the Separation Agreement (the “Transaction Taxes”). The parties agree to timely sign and deliver such certificates or forms as are requested by the other party and may be necessary or appropriate to enable such party to file promptly and timely the Tax Returns for such Transaction Taxes with the appropriate Taxing authorities and remit payment of the Transaction Taxes.

SECTION 2.05. Straddle Periods.

(a) The portion of any Covered Group Taxes constituting Alpha Taxes shall be computed on an Alpha Separate Group Basis. The remaining portion of any Covered Group Taxes shall constitute Generico Taxes.

(b) Any Tax (including escheat liability) other than Covered Group Taxes (which Taxes are addressed in Section 2.05(a) above) shall constitute (i) an Alpha Tax to the extent it relates to the Alpha Business (including any Tax relating to the Alpha Business attributable to a Pre-Distribution Period for which Gholdco is liable as the “successor” to Alpha for Tax purposes) and (ii) a Generico Tax to the extent it relates to the Generico Business.

SECTION 2.06. Pre-Closing vs. Post Closing Issues.

(a) Notwithstanding any other provision of this Agreement, any amount arising by virtue of (i) the exercise after the Distribution Date of any compensatory option to acquire New Alpha Common Stock or Gholdco Common Stock or (ii) the vesting after the Distribution Date of any restricted stock units in New Alpha or Gholdco shall be deductible by Gholdco, if the holder of such option or restricted stock unit was employed by Gholdco or a subsidiary of Gholdco from the date such option or restricted stock unit was granted through the date of exercise or vesting, as applicable, and deductible by New Alpha, if the holder of such option or restricted stock unit was employed by New Alpha or a subsidiary of New Alpha from the date such option or restricted stock unit was granted through the date of exercise or vesting, as applicable, in each case except as otherwise determined by the IRS in the Private Letter Ruling or a Final Determination.

9

(b) To the extent required by Applicable Laws, the Taxable year of each member of the Alpha Group shall close at the close of the Distribution Date and the Taxable income of such year for Income Tax purposes shall be computed taking into account the principles of Treasury Regulation Section 1.1502-76(b) or of a corresponding provision under the laws of an applicable state, local, municipal or foreign jurisdiction, except that no “ratable allocation election” for extraordinary items as defined thereunder will be made.

SECTION 2.07. Tax Attributes.

(a) Tax benefit carryforwards to Post-Distribution Periods, including net operating loss carryforwards, net capital loss carryforwards, foreign Tax credit carryforwards and research and development credit carryforwards shall be computed and allocated between the Alpha Business and the Generico Business based on the group that generated such item, except to the extent otherwise provided under Applicable Laws. To the extent that a Tax benefit relates to the Alpha Business but cannot as a matter of law be so allocated, the amount of such Tax benefit shall reduce any payment obligation of the Alpha Parties under this Agreement. To the extent that the amount of any such Tax benefit exceeds any payment obligation of the Alpha Parties under this Agreement, the Generico Parties shall pay the amount of such excess to the Alpha Parties when a benefit from such Tax benefit is realized.

(b) The allocation of earnings and profits between Gholdco and the Alpha Parties shall be reasonably determined by New Alpha pursuant to Section 312(h) of the Code and the Treasury Regulations promulgated thereunder within six months of the Distribution Date.

SECTION 2.08. Carryback Provisions. Unless the parties otherwise agree in writing, the Alpha Parties and the Generico Parties shall elect and shall cause each of the Alpha Subsidiaries or Generico Subsidiaries to elect, where permitted by Applicable Laws, to carry forward any loss, credit or similar Tax attribute arising in a Post-Distribution Period, with respect to a Covered Group Return (“Tax Carryover Attribute”) that could, in the absence of such election, be carried back to a Pre-Distribution Period. Any refund or credit of Taxes resulting from the required carryback to a Covered Group Return of any Tax Carryover Attribute attributable to the Alpha Business arising in a Post-Distribution Period shall be for the account and benefit of New Alpha; provided, however, that Gholdco shall only be required to pay such amount to New Alpha at the time such amount is actually realized in cash, credit, refund or offset by the Generico Group after taking into account (i) all other Tax attributes of the Affiliated Group and (ii) any carryback of any Tax Carryover Attribute attributable to the Generico Business. Any refund, credit or offset of Taxes resulting from the carryback of any Tax Carryover Attribute attributable to the Generico Business arising in a Post-Distribution Period shall be for the account and benefit of Gholdco. If a member of the Alpha Group recognizes a Tax Carryover Attribute that, under Applicable Laws, must be

10

carried back to a Pre-Distribution Period during which Alpha or any Alpha Subsidiary joined in filing a Tax Return on a consolidated, combined, or unitary basis with one or more of Gholdco, Generico or any Gholdco Subsidiary, Gholdco shall, at the expense of New Alpha, file appropriate refund claims within a reasonable period after being requested by New Alpha to do so, unless such filing shall materially adversely affect the liability or any attributes of the Generico Parties or any of their Affiliates under this Agreement (including the ability of any member of the Generico Group to carry back a Tax attribute), in which case such filing shall be subject to Gholdco’s prior written consent (such consent not to be unreasonably withheld). If a refund claim for which the Alpha Parties have received payment from the Generico Parties is subsequently disallowed by the relevant Governmental Entity, the Alpha Parties shall promptly return such payment to the Generico Parties together with any interest, penalties and additions to Tax resulting from such disallowance.

SECTION 2.09. General Tax Payments. With respect to any Taxes for which one party (the “Liable Party”) is liable under Article II and that are to be remitted in connection with Tax Returns to be filed by the other party (the “Filing Party”) after the Distribution Date, the Liable Party shall make any payment of estimated Taxes no later than the fifth day after receipt of written request (but not before the fifth date preceding the due date for such payment) from the Filing Party setting forth the Filing Party’s good faith estimate of the Liable Party’s portion of the estimated Taxes to be remitted. Promptly after the date that the Tax Return for the Taxable period is due (including extensions), the Filing Party shall provide a written request to the Liable Party describing in reasonable detail the amount of any true-up payment owed to the Filing Party and to be made by the Liable Party or any true-up payment owed by the Filing Party to the Liable Party as a result of an overpayment by the Liable Party. A true-up payment shall be made no later than fifteen (15) days after receipt of the written request for the true-up payment.

SECTION 2.10. Other Payments. Other payments due to a party under Article II shall be due (a) in the case of the receipt or crediting of a refund, five (5) days after such receipt or crediting and (b) in the case of a Final Determination, or the completion of an audit, assessment or examination or similar event, two (2) days prior to the date payment is to be made to the Governmental Entity. In the case of a delay in payment, the party required to have made payment shall pay interest to the other party at a rate equal to the prime rate of Citibank, N.A. in effect on the date such payment was required to be made plus 2%.

SECTION 2.11. Payment Failures. If any party required to make a payment hereunder fails to make such payment when required by this Agreement (or, if no required time period is specified, within 10 Business Days of written request by the party to whom the payment is due), the amount due shall bear interest at a rate equal to the prime rate of Citibank, N.A. in effect on the date such payment was required to be made plus 2%.

11

SECTION 2.12. Notice. Gholdco and New Alpha shall give each other prompt written notice of any payment that may be due under this Agreement, provided that any failure to notify shall not cause any party to forfeit substantive rights, except to the extent the other party is materially prejudiced thereby. Any payment that may be due under this Agreement is to be made by wire transfer of immediately available funds to the account designated by Gholdco or New Alpha in such notice or by any other method as shall be agreed upon by Gholdco and New Alpha.

SECTION 2.13. Amended Tax Returns. From and after the Distribution Date, the Generico Parties shall not, and shall not permit any of their Affiliates to, file any amended Tax Return for any Pre-Distribution Period or Straddle Period without the prior written consent of New Alpha (such consent not to be unreasonably withheld) unless such amended Tax Return does not materially adversely affect the liability or any attributes of the Alpha Parties or any of their Affiliates under this Agreement or the Separation Agreement (including the ability of New Alpha to carry back a Tax Carryover Attribute in accordance with Section 2.08).

Proc. 96-30, 1996-1 C.B. 696, or (ii) enter into any agreements or arrangements with respect to transactions or events (including, but not limited to, capital contributions or acquisitions, entering into any partnership or joint venture arrangements, stock issuances, stock acquisitions, option grants, or a series of such transactions or events (but excluding the Share Distribution)), in the case of each of clauses (i) and (ii) above that, if considered part of a plan that includes the Share Distribution would result in one or more Persons acquiring, directly or indirectly, stock of Gholdco or New Alpha representing a “50-percent or greater interest” therein within the meaning of Section 355(d)(4) of the Code (any act inconsistent with the acts described in Section 4.01 hereof and any act described in clauses (i) and (ii) above, collectively, the “Prohibited Acts”). Notwithstanding the foregoing, the following shall not be considered a Prohibited Act: (v) the issuance of any compensatory options by Gholdco, (w) the issuance of any Gholdco stock pursuant to any Gholdco compensatory option or restricted stock unit, and (x) the repurchase of any Gholdco restricted stock, in each case described in clauses (v), (w) and (x), if such action satisfies the conditions of Treasury Regulation § 1.355-7(d)(8)(i), and (y) the issuance of stock to a retirement plan qualified under Section 401(a) or 403(a) of the Code in a transaction that satisfies the requirements of Treasury Regulation Section 1.355-7(d)(9). For the avoidance of doubt, any issuance of additional equity or rights to acquire new equity by Gholdco to new investors during the Restricted Period shall be considered a Prohibited Act.

(b) Notwithstanding the foregoing, a party may take any of the Prohibited Acts, subject to Section 2.04, if, (i) in the case of the Alpha Parties and their Affiliates, (A) New Alpha first obtains (at its expense) an opinion in form and substance reasonably acceptable to Gholdco of Fried, Frank, Harris, Shriver & Jacobson LLP or another nationally recognized law firm or “big four” accounting firm reasonably acceptable to Gholdco, which opinion may be based on usual and customary factual representations, or (B) at New Alpha’s request, Gholdco (at New Alpha’s expense) obtains a supplemental ruling from the IRS, or, (ii) in the case of Gholdco and its Affiliates, (A) Gholdco first obtains (at its expense) an opinion in form and substance reasonably acceptable to New Alpha of a nationally recognized law firm or “big four” accounting firm reasonably acceptable to New Alpha, which opinion may be based on usual and customary factual representations or (B) Gholdco (at its expense) obtains a supplemental ruling from the IRS, in each case that such Prohibited Act(s), and any transaction related thereto, should not affect (i) the qualification of the Share Distribution under Section 355 and Section 368(a)(1)(D) of the Code and (ii) the nonrecognition of gain to Gholdco in the Share Distribution. A party may also take any of the Prohibited Acts, subject to Section 2.04, with the written consent of the other party in the other party’s sole and absolute discretion. During the Restricted Period, the parties shall provide, and shall cause their respective

14

Affiliates to provide, all information reasonably requested by the other party relating to any transaction involving an acquisition (directly or indirectly) of that party’s stock within the meaning of Section 355(e) of the Code. The parties hereto agree that the payment of monetary compensation would not be an adequate remedy to a breach of the obligations described in the Prohibited Acts, and each party consents to the issuance and entry of an injunction to prevent a breach of the obligations contained in the Prohibited Acts, subject to the waiver and consent described in the preceding sentence. New Alpha represents that, to its knowledge, from the date of this Agreement until the time of the Share Distribution, and except as contemplated by the Transaction Agreements, there will be no agreement, understanding, arrangement or substantial negotiations by Gholdco (or any of its Subsidiaries) concerning any acquisition of Gholdco stock for purposes of applying Treas. Reg. § 1.355-7(d)(3) and an opinion and/or ruling obtained in accordance with Section 4.02(b)(ii) may assume the accuracy of such representation.

(c) Notwithstanding anything in this Agreement to the contrary, a party shall be responsible for, and shall indemnify the other party and hold the other party harmless from, any Restructuring Taxes resulting from any Prohibited Act taken by such party or any of their Affiliates, regardless of whether the exception contained in Section 4.02(b) is satisfied with respect to such act.

SECTION 4.03. Cooperation with Respect to Tax Return Filings, Examinations and Tax Related Controversies. In addition to any obligations imposed pursuant to the Separation Agreement, each party shall fully cooperate with the other party and its representatives, in a prompt and timely manner, in connection with (i) the preparation and filing of and (ii) any inquiry, audit, redetermination, examination, investigation, dispute, or litigation involving, any Tax Return required to be filed by such other party pursuant to this Agreement. Such cooperation shall include, but not be limited to, (A) the execution and delivery to such other party of any power of attorney required to allow such other party and its counsel to participate in or control any inquiry, audit or other administrative proceeding and to assume the defense or prosecution, as the case may be, of any suit, action or proceeding pursuant to the terms of and subject to the conditions set forth in Article III, and (B) making available, during normal business hours, and within 15 days of any written request therefor, all books, records and information, and the assistance of all officers and employees, necessary or useful in connection with the preparation of any Tax return or any Tax inquiry, audit, redetermination, examination, investigation, dispute, litigation or any other matter. Any recoveries by the Generico Parties, the Alpha Parties, or any of their respective Affiliates against third parties (including awards for damages) relating to Restructuring Taxes shall be shared and allocated by the parties consistently with the allocation of the underlying Restructuring Taxes.

ARTICLE V

RETENTION OF RECORDS; ACCESS

The Alpha Group and the Generico Group shall retain all Information in accordance with Section 6.04 of the Separation Agreement. At or prior to the Distribution Date, New Alpha shall make available to Gholdco to copy all consolidated, combined and unitary Tax Returns of the Affiliated Group and all notes, workpapers, correspondence and other records related thereto.

ARTICLE VI

DISPUTES

From and after the Distribution Date, if New Alpha and Gholdco cannot agree on the calculation of any liability under this Agreement, or the interpretation or application of any provision under this Agreement, either party may provide to the other party written notice of intent to invoke the dispute resolution procedures of this Article VI. Within 10 days following the receipt of such written notice, New Alpha and Gholdco shall jointly retain a nationally recognized law firm or “big four” accounting firm, which firm is independent of both parties (the “Independent Firm”), to resolve the dispute. If the parties cannot jointly agree on an Independent Firm to resolve the dispute within the 10 day period, then each party shall select a nationally recognized law firm or “big four” accounting firm, which firm is independent of both parties, and both law or accounting firms shall jointly select an Independent Firm which shall make the determination under this Article VI. The Independent Firm shall act as an arbitrator to resolve all points of disagreement and its decision shall be final and binding upon all parties involved. The Independent Firm shall determine the appropriate outcome based upon this Agreement with respect to each disputed item. The Independent Firm shall have 90 days from the date that it is selected in which to make such determinations, unless New Alpha and Gholdco mutually agree on an extension of such period or the Independent Firm, in its discretion, determines that an extension of such period is warranted by exceptional circumstances. New Alpha and Gholdco shall provide the Independent Firm with such information or documentation as the Independent Firm deems in its discretion to be necessary for it to make the determinations requested of it. Any determination by the Independent Firm shall be in writing. Following the decision of the Independent Firm, New Alpha and Gholdco shall each take or cause to be taken any action necessary to implement the decision of the Independent Firm. The fees and expenses relating to the Independent Firm shall be borne by the party that such Independent Firm determines has lost the dispute. Notwithstanding the foregoing, this Article VI shall not apply to any dispute arising under Section 2.04 or 4.02(c) with respect to the respective liability of the parties in the event Restructuring Taxes are imposed.

16

ARTICLE VII

SURVIVAL OF LIABILITIES

Notwithstanding any other provision in this Agreement, any liabilities under this Agreement shall survive for 60 days following any applicable statute of limitation; provided, however, that each party may continue to demand the full amount of payment to be made with respect to any such liabilities under this Agreement and such liabilities shall continue to survive until paid in full in accordance with this Agreement.
