(a) Post-Closing Adjustment to Merger Consideration. Upon the final determination of the CMS Reconciliation Payment Amount pursuant to this Section 2.12, the Merger Consideration shall be adjusted as follows: (a) if the CMS Reconciliation Payment Amount is a positive number, then the Merger Consideration shall be increased on a dollar for dollar basis by the CMS Reconciliation Payment Amount and (b) if the CMS Reconciliation Payment Amount is a negative number, then the Merger Consideration shall be decreased on a dollar for dollar basis by the CMS Reconciliation Payment Amount. If the CMS Reconciliation Payment Amount is zero, the Merger Consideration shall not be adjusted pursuant to this Section 2.12. If the adjustments pursuant to this Section 2.12 result in an increase in the Merger Consideration, Parent shall pay to each Person who received the Initial Merger Consideration its pro rata share of such increase in accordance with Section 2.12(e) below. If the adjustments pursuant to this Section 2.12 result in a reduction in the Merger Consideration, the Indemnifying Members shall be severally obligated to pay to Parent their respective Indemnification Percentage of such decrease in accordance with Section 2.12(e) below. Payments made pursuant to this Section 2.12 shall not be subject to any right of setoff.

(b) Pre-Closing Finalization of the CMS Reconciliation Process. Notwithstanding the foregoing, the parties hereto acknowledge and agree that it may be possible to calculate and finalize the CMS Reconciliation Payment Amount prior to the Closing depending on when the 2006 CMS Reconciliation becomes final. In the event that the CMS Reconciliation Amount does become final prior to the Closing, the parties shall seek to agree on the Actual Net CMS Reconciliation Amount and the CMS Reconciliation Payment Amount prior to Closing and if possible adjust the Initial Merger Consideration accordingly. For such purposes, the review and dispute resolution provisions of Section 2.12(d) shall apply.

(c) CMS Reconciliation Process. In connection with the Company’s participation in the process by which CMS calculates final payments and determines if any retroactive adjustment or reconciliation is necessary pursuant to 42 C.F.R. 423.343 for the 2006 plan year (the "2006 CMS Reconciliation"), the Company and Parent shall use their commercially reasonable efforts to conduct the 2006 CMS Reconciliation in good faith and in accordance with the prescribed methodology required pursuant to 42 C.F.R. 423.343.

(a) From and after the Closing Date, the Governing Documents of the Second Merger Surviving Entity and its Subsidiaries shall contain provisions no less favorable with respect to the limitation or elimination of liability and indemnification than are set forth in the Governing Documents of the Company and its Subsidiaries as of the date of this Agreement, which provisions shall not be amended, repealed or otherwise modified for a period of six (6) years after the Closing in any manner that would adversely affect the rights thereunder of individuals who at or prior to the Closing were directors, officers, agents or employees of the Company or any of its Subsidiaries or who were otherwise entitled to indemnification pursuant to the Governing Documents of the Company or any of its Subsidiaries.

(b) On the Closing Date, Parent shall, or shall cause the Second Merger Surviving Entity to, purchase, at Parent's expense, a directors' and officers' liability insurance tail policy to be effective for a period of six (6) years beginning on the Closing Date with respect to matters existing or occurring on or prior to the Closing Date (including the transactions contemplated by this Agreement) covering all persons who are currently covered by the Company's existing officers' and directors' liability insurance policies on terms no less advantageous to persons covered thereby than those contained in such existing insurance policies; provided, that Parent and the Second Merger Surviving Entity shall not be required to pay an amount for such tail policy that is in excess of $101,400 (which is equal to 300% of the last annual premium paid by the Company for its directors' and officers' liability insurance); provided, further, that if such amount is insufficient to procure the tail coverage contemplated by this Section 5.10(b), Parent shall, or shall cause the Second Merger Surviving Entity to, after consultation with the Shareholder Representative, purchase as much comparable insurance coverage as can be obtained for such amount.

(c) From and after the Closing Date, Parent shall, or Parent shall cause the Second Merger Surviving Entity to, indemnify, hold harmless and defend each individual who served as a director or officer of the Company or any of its Subsidiaries at any time prior to the Closing Date from and against all actions, suits, proceedings, hearings, investigations, claims, etc., including all court costs and reasonable attorneys' fees and expenses, resulting from or arising out of acts or omissions (or alleged acts or omissions) by them in their capacities as such, which acts or omissions occurred at or prior to the Closing; provided, however, that the indemnification obligations under this Section 5.10(c) shall not be deemed to eliminate or reduce the liability under Article 8 hereof of any Indemnifying Member who also served as a director or officer of the Company or any of its Subsidiaries prior to the Closing Date.

(d) The provisions of this Section 5.10 are (i) intended to be for the benefit of, and shall be enforceable by, each Person entitled to indemnification under this Section 5.10, and each such Person's heirs, legatees, representatives, successors and assigns, it being expressly agreed that such Persons shall be third-party beneficiaries of this Section 5.10 and (ii) in addition to, and not in substitution for, any other rights to indemnification that any such Person may have by contact or otherwise.

(e) In the event Parent or the Second Merger Surviving Entity or any of their respective successors or assigns (i) consolidates with or merges into any other Person and is not

Certain Tax Matters; Plan of Reorganization.

(a) If the transactions contemplated by this Agreement are consummated, all transfer, documentary, sales, use, stamp, registration and other such Taxes, and all conveyance fees, recording charges and other fees and charges (including any penalties and interest), incurred in connection with consummation of the transactions contemplated by this Agreement shall be paid by Parent or the Second Merger Surviving Entity (otherwise, such fees and charges shall be payable by the party incurring such expense).

(b) This Agreement is intended to constitute a "plan of reorganization" within the meaning of Section 1.368-2(g) of the income tax regulations promulgated under the Code.

(c) If any Tax Return for the Company or any of its Subsidiaries for any Tax period ending on or before the Closing is to be filed after the Closing Date, Parent will provide a copy of such Tax Return to the Shareholder Representative for its review and comment at least 15 days prior to filing such Tax Return. All reasonable comments of the Shareholder Representative will be incorporated in such Tax Return if such comments are consistent with past practice as in effect immediately prior to the Closing Date, and if the failure to incorporate such comments could reasonably be expected to have a material adverse effect on any individual who was a shareholder or employee of the Company immediately prior to the Closing Date. All other reasonable comments of the Shareholder Representative will be considered in good faith for inclusion in such Tax Return by the Company. Prior to the Closing, Company shall advise Parent of the amount of any Tax withholding obligation of the Company or any Subsidiary of the Company arising in connection with the transactions contemplated by this Agreement, which information the Parent will rely upon for purposes of withholding from the Merger Consideration and causing the Company to withhold as required.

(d) on or prior to the Closing Date, MHRx shall cause the Limited Liability Company Agreement of MHRx LLC (the "LLC Agreement") to be amended to provide that the proviso to Section 4.4(a)(B)(iii) of the LLC Agreement that was added by Amendment No. 1 to the LLC Agreement will be amended to delete the existing parenthetical: "(it being agreed by the Company and Xxxxxxx X. Xxxxxxxx that any such amounts distributable to Xxxxxxx X. Xxxxxxxx shall be treated as a guaranteed payment under Section 707(c) of the Code when paid)" and to provide that any consideration received by Xxxxxxx X. Xxxxxxxx with respect to his Class D Units in excess of the pro rata consideration received by other holders with respect to their Class D Units will be treated either as a guaranteed payment by MHRx under Section 707(c) of the Code or as a payment of compensation by the Company.

No claim may be brought hereunder in respect of any covenant or agreement that contemplates performance entirely before or at the Closing unless such claim is brought prior to the twelve month anniversary of the Closing Date.

Section 8.2

Indemnification.

(a) Indemnification by the Company Shareholders. Subject to the limitations set forth in this Article 8, from and after the Closing Date, the shareholders of the Company at the First Merger Effective Time shall indemnify and hold harmless Parent and each of its direct and indirect Affiliates, officers, directors, members, managers, partners, employees, agents and other representatives (collectively, the "Parent Indemnified Persons") solely through the payment to Parent of Escrow Cash and the transfer to Parent of Escrow Shares held in the escrow account

-79-

maintained pursuant to the Escrow Agreement (but only if and to the extent that Escrow Funds are available to satisfy such Losses), from, against and in respect of any and all liabilities, losses, damages, fines, penalties, fees, costs and expenses (in each case, including reasonable attorneys' fees and expenses) (collectively, "Losses"), incurred or suffered by such Parent Indemnified Persons as a result of:

(i) any breach of, or inaccuracy in, any representation or warranty made by MHRx or the Company in this Agreement or in any certificate delivered pursuant to this Agreement, in each case at or before Closing;

(ii) any material breach or violation of any covenant or agreement of MHRx or the Company pursuant to this Agreement at or before Closing; or

(iii) the exercise of dissenters or appraisal rights by any holder of Company Common Stock.

(iv) any fees and expenses (including those of investment bankers, lawyers, accountants and other advisers) incurred by MHRx, the Company or any Subsidiaries of the Company in connection with the negotiation, execution and delivery of this Agreement and the consummation of the transactions contemplated by this Agreement (the "Seller Transaction Expenses") to the extent such Seller Transactions Expenses are not paid out of the Initial Cash Merger Consideration as contemplated by Section 8.6.

For the purposes of clause (i) of this Section 8.2(a), the representations and warranties of the Company contained in Article 3 of this Agreement (other than the first sentence of Section 3.9) shall be read as if all qualifications as to materiality, including each reference to the terms and phrases "material", "in all material respects" or like phrases, and the defined term "Company Material Adverse Effect", were deleted therefrom in determining whether there has been a breach of any such representation or warranty.

(b) Subject to the limitations set forth in this Article 8, from and after the Closing Date, the members of MHRx (or beneficiaries of trusts who are members of MHRx) who are party to Joinder Agreements (each, an "Indemnifying Member" and collectively, the "Indemnifying Members") shall indemnify and hold harmless each of the Parent Indemnified Persons from, against and in respect of such Indemnifying Member's Indemnification Percentage of any and all Losses (x) incurred or suffered by such Parent Indemnified Persons as a result of any breach of, or inaccuracy in, any representation or warranty made by the Company in Section 3.1 (first sentence only), 3.2, 3.5, 3.12, 3.15(i), 3.24, 3.25 or 3.26 or (y) subject to indemnification under Section 8.2(a)(iv), in either case, only to the extent the Parent Indemnified Persons cannot recover such Losses from the Escrow Fund under Section 8.2(a) as a result of the Escrow Fund being insufficient to satisfy such Losses.

(c) Indemnification by Parent. Subject to the limitations set forth in this Article 8, from and after the Closing Date, Parent shall indemnify and hold harmless each of the shareholders of the Company at the First Merger Effective Time and each of the Indemnifying Members and each of their respective direct and indirect Affiliates, officers, directors, members,

-80-

managers, partners, employees, agents and other representatives (collectively, the "MHRx Indemnified Persons"), from, against and in respect of any and all Losses, incurred or suffered by such MHRx Indemnified Persons as a result of:

(i) any breach of, or inaccuracy in, any representation or warranty made by Parent or the Merger Subs in this Agreement or in any certificate delivered pursuant to this Agreement;

(ii) any material breach or violation of any covenant or agreement of Parent or the Merger Subs pursuant to this Agreement; or

(iii) any material breach or violation of any covenant or agreement of the Second Merger Surviving Entity after the Closing.

For the purposes of clause (i) of this Section 8.2(c), the representations and warranties of Parent contained in Article 4 of this Agreement (other than the first sentence of Section 4.9) shall be read as if all qualifications as to materiality, including each reference to the terms and phrases "material", "in all material respects" or like phrases, and the defined term "Parent Material Adverse Effect", were deleted therefrom in determining whether there has been a breach of any such representation or warranty.

(d)

Limitations on Liability.

(i) Other than with respect to Losses subject to indemnification under Section 8.2(a)(iv), neither the Parent Indemnified Persons nor the MHRx Indemnified Persons shall be entitled to assert any claim for indemnification under this Article 8 with respect to a single course of conduct or related set of circumstances, occurrences or events unless the Losses arising therefrom exceed $150,000 (any Losses in excess of such amounts being referred to herein as "Indemnifiable Losses").

(ii) Other than with respect to Losses subject to indemnification under Section 8.2(a)(iii) or Section 8.2(a)(iv), neither the Parent Indemnified Persons (in respect of Sections 8.2(a) and 8.2(b)) nor the MHRx Indemnified Persons (in respect of Section 8.2(c)) shall be entitled to assert any claim for indemnification hereunder until such time as the aggregate of all Indemnifiable Losses that such Parent Indemnified Persons or such MHRx Indemnified Persons may have under Section 8.2(a), Section 8.2(b) or Section 8.2(c), as the case may be, exceed $10,000,000, and then only for the amount by which such claims exceed such deductible amount.

(iii) The maximum liability of each Indemnifying Member for any Indemnified Loss under Section 8.2(b) shall not exceed the amount of such Indemnified Loss multiplied by the Indemnification Percentage of such Indemnifying Member. For purposes of this Agreement, "Indemnification Percentage" means a fraction, the numerator of which is such Indemnifying Member's pro rata share of the Initial Merger Consideration, and the denominator

-81-

of which is the aggregate Initial Merger Consideration payable to all Indemnifying Members.

(iv) The maximum aggregate liability of all Indemnifying Members for indemnification claims under Sections 8.2(a) and 8.2(b) shall be limited to the Purchase Price.

(v) The maximum aggregate liability of Parent for indemnification claims under this Article 8 shall be limited to $31,500,000, except with respect to indemnification under Section 8.2(c)(i) in respect of breaches of the representations and warranties contained in Sections 4.1 (first sentence only), 4.2, 4.5, 4.12, 4.22, 4.23, 4.24, 4.25 and 4.26 (for which liability will be limited to an amount equal to the Purchase Price).

(vi) The amount of Losses for which indemnification is available under this Article 8 shall be calculated to appropriately take into account the amount of Tax Benefits (as defined below) actually realized by the Person entitled to seek indemnification hereunder (the "Indemnified Person"), through (x) a reduction in cash Tax payments required to be made by the Indemnified Person or any of its Affiliates, (y) an offset against Taxes otherwise actually payable in cash by the Indemnified Person or any of its Affiliates or (z) the receipt of Tax refunds in cash by the Indemnified Person of any of its Affiliates (collectively, "Tax Benefits"), in each case, which Tax Benefits result from, or arise from the same circumstances as, the Losses. If the Indemnified Person is liable for any additional Taxes as a result of the payment of amounts in respect of a Loss, the Indemnifying Party (as defined below) will pay an additional amount such that the Indemnified Person shall have received from the Indemnifying Party, net of the payment of Taxes, an amount equal to the Loss. In addition, the amount of Losses for which indemnification is available under this Article 8 shall be calculated net of any amounts actually recovered by the Indemnified Person under insurance policies with respect to such Losses. The Second Merger Surviving Entity shall use commercially reasonable efforts to seek full recovery, to the fullest extent possible, under all insurance policies covering any Losses to the same extent as it would if such Losses were not subject to indemnification hereunder, and the Second Merger Surviving Entity shall not take steps to terminate or cancel any occurrence-based insurance policies of the Company in effect for periods prior to the Closing. In the event that any party required to provide indemnification under this Article 8 (the "Indemnifying Party") makes any payment hereunder in respect of any Losses, such Indemnifying Party shall be subrogated, to the extent of such payment to the rights of such Indemnified Person against any insurer (to the extent permitted under applicable insurance policies) or other third Persons with respect to such Losses. In addition, the amount of Losses for which indemnification is available under this Article 8 shall be net of all related reserves reflected on the Latest Company Balance Sheet or the Latest Parent Balance Sheet, as applicable, each as adjusted through the Closing Date to give effect to the passage of time and, in respect of Losses subject to indemnification under Section 8.2(a) or 8.2(b) relating to Taxes, net of any

-82-

Indemnifiable Tax Benefits (as defined below) actually realized by Parent or any of its Affiliates with respect to any net operating losses available to the Company or any of its Subsidiaries as of the close of business on December 31, 2006; it being understood that to the extent that Parent or any of its Affiliates actually realize any such Indemnifiable Tax Benefit after receiving an indemnification payment for any Losses relating to Taxes, Parent shall remit to the Shareholder Representative an amount equal to the amount of any such Indemnifiable Tax Benefit to the extent that the amount of such Indemnifiable Tax Benefit does not exceed the cumulative indemnification payments relating to Taxes received by Parent and any of its Affiliates and not previously offset by Indemnifiable Tax Benefits. An "Indemnifiable Tax Benefit" shall mean any Tax Benefit or Tax Benefits relating to net operating losses, that alone exceeds or in the aggregate exceed $150,000, it being understood that the full amount of any Indemnifiable Tax Benefit, including the amount below $150,000, shall be recoverable by the Shareholder Representative as provided in this Section 8.2(d)(vi). After the Closing, upon and after becoming aware of any event or circumstance that could reasonably be expected to give rise to any Losses with respect to which indemnification may be required hereunder, the Parent Indemnified Persons or MHRx Indemnified Persons, as the case may be, will use their commercially reasonable efforts to mitigate all Losses pursuant to which indemnification is available hereunder (including, with respect to any claim based on a breach of the representation set forth in Section 3.12(l), by first pursuing any rights against Persons receiving the compensation for which withholdings were not made prior to making any indemnification claim hereunder).

(vii) No party will in any event be liable under this Article 8, and no claim for indemnification may in any event be asserted under this Article 8, for any loss of profits or earnings, or any punitive, indirect, incidental or consequential damages by reason of a breach of any representation, warranty, covenant or indemnity contained herein; provided that the foregoing is not intended to limit recovery of amounts paid by an Indemnified Person in connection with the defense, settlement or other resolution of any Third Party Claim (including any punitive, indirect, incidental or consequential damages paid by an Indemnified Person to any third party).

(viii) For the avoidance of doubt, in no event will any Indemnifying Member have any indemnification obligation under this Section 8.2 relating to Taxes on the Reserve Adjusted Net CMS Reconciliation Amount received by the Company.

(e)

Payment of Claims.

(i) Subject to Section 2.14, if Section 8.2(a) requires that an Indemnifiable Loss be satisfied from the Escrow Fund, (i) a total number of Escrow Shares equal to the lesser of (x) the total number of Escrow Shares remaining in the Escrow Fund and (y) a number of Escrow Shares determined by dividing 45% of such Indemnifiable Loss by the Fair Market Value of a share of

-00-

Xxxxxx Xxxxxx Stock (provided that if the Parent Common Stock is then traded on the NASDAQ Global Select Market, such Fair Market Value shall be determined by reference to the average of the high and low trading price of the Parent Common Stock on a ten trailing day average basis for the last ten trading days immediately preceding the date such Indemnifiable Loss became payable under Section 8.2(a) and (ii) Escrow Cash, in an amount equal to the lesser of (x) the amount of Escrow Cash remaining in the Escrow Fund and (y) such amount of the Indemnifiable Loss that is not paid in Escrow Shares pursuant to clause (i) above (valued as provided above), shall be paid from the Escrow Fund to Parent. Subject to Section 2.14, to the extent that the amount of Escrow Shares or Escrow Cash remaining in the Escrow Fund is insufficient to pay the portion of an Indemnifiable Loss pursuant to clause (i) or clause (ii), as the case may be, of the previous sentence in its entirety, and Escrow Shares or Escrow Cash remain in the Escrow Fund at such time, the remaining Escrow Shares or Escrow Cash shall be used to satisfy the remainder of such Indemnifiable Loss.

(ii) Subject to Section 2.14, if Section 8.2(b) or Section 8.2(c) requires that an Indemnifiable Loss be satisfied other than from the Escrow Fund, such Indemnifiable Loss shall be satisfied by means of the delivery to the Indemnified Person of (i) a total number of shares of Parent Common Stock determined by dividing 45% of such Indemnifiable Loss by the Fair Market Value of a share of Parent Common Stock (provided that if the Parent Common Stock is then traded on the NASDAQ Global Select Market, such Fair Market Value shall be determined by reference to the average of the high and low trading price of the Parent Common Stock on a ten trailing day average basis for the last ten trading days immediately preceding the date such Indemnifiable Loss became payable under Section 8.2(b) or Section 8.2(c), as applicable), and (ii) cash (by wire transfer of immediately available funds to an account or accounts designated by the Indemnified Person, in an amount equal to such amount of the Indemnifiable Loss that is not paid in shares of Parent Common Stock; provided, however, that any Indemnifying Member that is obligated to make an indemnification payment to Parent pursuant to Section 8.2(b) may, at its election, pay more than 55% of such payment amount by wire transfer of immediately available funds. In the event that Parent or any other Parent Indemnified Person proposes to make any claim for indemnification pursuant to Section 8.2(b), the Indemnified Person making the claim shall give notice to the Shareholder Representative (which notice shall be given, as soon as reasonably practical after the Parent Indemnified Person determines in good faith that it is entitled to bring such claim). Any such notice shall describe the facts giving rise to the claim in reasonable detail (in light of the circumstance known at the time).

(f)

Third Party Claims.

(i) Notice of Claim. If any third party notifies an Indemnified Person with respect to any matter (a "Third Party Claim") which may give rise to a claim for indemnification against an Indemnifying Party, then the Indemnified Person will promptly (and, in any event, within twenty (20) Business Days) give written

-84-

notice thereof to the Indemnifying Party; provided, that no delay on the part of the Indemnified Person in notifying the Indemnifying Party will relieve the Indemnifying Party from any obligation under this Article 8, except to the extent such delay actually and materially prejudices the Indemnifying Party.

(ii) Assumption of Defense, etc. The Indemnifying Party will be entitled to participate in the defense of any Third Party Claim that is the subject of a notice given by the Indemnified Person pursuant to Section 8.2(f)(i). In addition, upon written notice to the Indemnified Person, the Indemnifying Party will have the right to defend the Indemnified Person against the Third Party Claim with counsel of its choice reasonably satisfactory to the Indemnified Person, except in the case of Third Party Claims involving Taxes under the special circumstances described in clause (v) below in which such clause (v) shall govern. In such event, the Indemnified Person may retain separate co-counsel at its sole cost and expense and participate in the defense of the Third Party Claim. Notwithstanding the foregoing, the Indemnifying Party will not consent to the entry of any judgment or enter into any compromise or settlement with respect to the Third Party Claim without the prior written consent of the Indemnified Person unless such judgment, compromise or settlement (a) provides for the payment by the Indemnifying Party of money as sole relief for the claimant and (b) results in the full and general release of all Indemnified Persons from all liabilities arising or relating to, or in connection with, the Third Party Claim. For the avoidance of doubt, any amounts incurred in connection with the defense, settlement or other resolution of any Third Party Claims shall be deemed to be Losses for purposes of the limitations set forth in Section 8.2(d).

(iii) Indemnified Person's Control. If the Indemnifying Party does not deliver the notice contemplated by Section 8.2(f)(ii) within twenty (20) days after the Indemnified Person has given notice of the Third Party Claim pursuant to Section 8.2(f)(i), the Indemnified Person may defend, and may consent to the entry of any judgment or enter into any compromise or settlement with respect to, the Third Party Claim; provided, that the Indemnifying Party will not be bound by the entry of any such judgment consented to, or any such compromise or settlement effected, without its prior written consent (which consent will not be unreasonably withheld or delayed).

(iv) Remedies Exclusive. The parties agree that, except as otherwise expressly provided in Section 8.15, from and after the Closing the remedies provided for in this Article 8 shall constitute the sole and exclusive remedy for all Losses that any such party may suffer or incur arising from or relating to this Agreement or the transactions contemplated hereby and the parties hereto hereby waive any other rights or remedies that may arise under any applicable Legal Requirements and any equitable remedies (provided that the foregoing shall not be deemed to in any way limit the rights or remedies of any MHRx Indemnified Person (or Affiliate thereof) who is a participant in the Equity Financing under Securities Purchase Agreement or any other documents or agreements relating thereto).

-85-

(v) Certain Third Party Claims Involving Taxes. If the Third Party Claim involves a Tax dispute that (A) includes a Tax for which the Indemnified Person could be liable but for which no indemnity is available hereunder, (B) the amount of Tax at issue in clause (A) is larger than the Loss at issue (taking into account any reasonably anticipated netting effects pursuant to Section 8.2(d) hereof), and (C) the two Tax issues cannot be segregated or severed and defended separately, then, the Indemnified Person shall control the defense of the Third Party Claim, although the Indemnifying Party shall have the right to participate in such defense, including (with the Indemnified Person's consent, not to be unreasonably withheld) the right to participate on a face-to-face basis in any audit, administrative appeal, court proceeding or settlement discussions, all at its own cost and expense. Subject to such continuing participation, the Indemnified Person may consent to the entry of any judgment or enter into any compromise or settlement with respect to the Third Party Claim; provided, that the Indemnified Person and the Indemnifying Party shall consult in good faith about any such judgment, compromise or settlement. If the parties are not able to agree on the disposition of the Third Party Claim, the parties will again attempt to sever from such Third Party Claim any dispute regarding any Tax described in clause (A) of this clause (v). If such attempted severance occurs, the Indemnifying Party will take over the defense of the Third Party Claim. If such attempted severance does not occur, the Indemnified Person has the ultimate right to decide on the disposition of the Third Party Claim, provided that if the Indemnifying Party objects in writing to the judgment, compromise, or settlement, then the Indemnifying Party may take over the defense of the Third Party Claim, in which case the Indemnifying Party shall be liable to the Indemnified Person for the full amount by which the judgment, compromise or settlement exceeds the amount that would have been obtained in the original judgment, compromise, or settlement (to which the Indemnifying Party objected). If the defense of the Third Party Claim conducted by the Indemnifying Party results in a judgment, compromise or settlement amount that is less than the amount that would have been obtained in the original judgment, compromise or settlement (to which the Indemnifying Party objected), then the Indemnifying Party may offset any Indemnifiable Loss otherwise due to the Indemnified Person by the difference between such amounts. The principles of the foregoing procedures shall also apply to the right to participation, defense and disposition of Third Party Claims in which clauses (A) and (C) hereof apply (but not (B)). Other than with respect to the foregoing provisions of this clause (v), the provisions of clauses (i)-(iii) above shall govern.

(g) Tax Treatment. The parties will treat any payment received pursuant to this Article 8 as an adjustment to the Merger Consideration for Tax and financial reporting purposes to the extent permissible under applicable Legal Requirements.

Section 8.4 Exhibits and Schedules. All exhibits and schedules hereto, or documents expressly incorporated into this Agreement, are hereby incorporated into this Agreement and are hereby made a part hereof as if set out in full in this Agreement. The inclusion of any information in the Disclosure Schedules will not be deemed an admission or acknowledgment, in and of itself and solely by virtue of the inclusion of such information in the Disclosure Schedules, that such information is required to be listed in any Disclosure Schedule or that such items are material to any party hereto or any of their respective Subsidiaries. The headings, if any, of the individual sections of each of the Disclosure Schedules are inserted for convenience

-88-

only and will not be deemed to constitute a part thereof or a part of the Agreement. The Disclosure Schedules are arranged in sections and subsections that correspond to the sections and subsections of this Agreement merely for convenience, and the disclosure of an item in one section or subsection of the Disclosure Schedules as an exception to a particular covenant, representation or warranty will be deemed adequately disclosed as an exception with respect to all other covenants, representations or warranties herein to the extent that the relevance of such item to such other covenants, representations or warranties is reasonably apparent on its face, notwithstanding (x) the presence or absence in this Agreement of an appropriate reference to the section or subsection of the Disclosure Schedules, (y) the presence or absence in the Disclosure Schedules of an appropriate reference to the section or subsection of this Agreement to which such disclosure relates or (z) an appropriate cross-reference thereto.

Section 8.5 Time of the Essence; Computation of Time. Time is of the essence for each and every provision of this Agreement. Whenever the last day for the exercise of any privilege or the discharge or any duty hereunder shall fall upon a day that is not a Business Day, the party having such privilege or duty may exercise such privilege or discharge such duty on the next succeeding day which is a regular Business Day.

Section 8.6 Expenses. Except as otherwise set forth in this Agreement, and subject to Section 8.2(a)(iv), regardless of whether the transactions provided for in this Agreement are consummated, each party hereto shall pay its own expenses incident to this Agreement; provided, that if the transactions contemplated by this Agreement are completed, at the Closing the parties shall pay all Seller Transaction Expenses as directed by MHRx out of the Initial Cash Merger Consideration (and the associated reduction of the Initial Cash Merger Consideration by the amount of such fees and expenses will be treated as an adjustment to the Cash Merger Consideration for Tax and financial reporting purposes).

Section 8.7 Governing Law. All issues and questions concerning the construction, validity, enforcement and interpretation of this Agreement and the schedules and exhibits hereto shall be governed by, and construed in accordance with, the laws of the State of New York without giving effect to any choice of law or conflict of law rules or provisions that would cause the application of the laws of any jurisdiction other than the State of New York.

Section 8.8 Jurisdiction and Venue; Waiver of Jury Trial. Except as otherwise provided in Sections 2.12 and 2.13, each of the parties submits to the exclusive jurisdiction of any state or federal court sitting in New York, New York, in any action or proceeding arising out of or relating to this Agreement, agrees that all claims in respect of the action or proceeding may be heard and determined in any such court and agrees not to bring any action or proceeding arising out of or relating to this Agreement in any other court. Each of the parties waives any defense of inconvenient forum to the maintenance of any action or proceeding so brought and waives any bond, surety or other security that might be required of any other party with respect thereto. Each party agrees that service of summons and complaint or any other process that might be served in any action or proceeding may be made on such party by sending or delivering a copy of the process to the party to be served at the address of the party and in the manner provided for the giving of notices in Section 8.3. Nothing in this Section 8.8, however, shall affect the right of any party to serve legal process in any other manner permitted by law. Each party agrees that a final, non-appealable judgment in any action or proceeding so brought shall

-89-

be conclusive and may be enforced by suit on the judgment or in any other manner provided by law. EACH OF THE PARTIES HERETO IRREVOCABLY WAIVES ANY AND ALL RIGHTS TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATED TO THIS AGREEMENT.

Section 8.9 Assignment; Successors and Assigns; No Third Party Rights. Except as otherwise provided herein, this Agreement may not, without the prior written consent of the other parties hereto, be assigned by any party hereto by operation of law or otherwise, and any attempted assignment shall be null and void; provided that, without the consent of the Company, Parent and Merger Sub shall be permitted to make a collateral assignment of this Agreement to any financial institution and Merger Sub may assign its rights hereunder to one or more wholly-owned Subsidiaries of Parent or Merger Sub upon written notice of such assignment to the Company, it being understood that no assignment of this Agreement shall relieve the transferor of any of its obligations hereunder. Notwithstanding the foregoing, no assignment shall be permitted that could reasonably be expected to impact the tax treatment of the Mergers. Subject to the foregoing, this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective heirs, successors, permitted assigns and legal representatives. Except as set forth in Section 5.10, and except for the rights of the holders of Certificates hereunder, this Agreement shall be for the sole benefit of the parties to this Agreement and their respective heirs, successors, permitted assigns and legal representatives and is not intended, nor shall be construed, to give any Person, other than the parties hereto and their respective heirs, successors, assigns and legal representatives, any legal or equitable right, remedy or claim hereunder. Nothing in this Agreement, expressed or implied, is intended to or shall constitute the parties hereto partners or participants in a joint venture.

Section 8.10 Counterparts. This Agreement may be executed in one or more counterparts for the convenience of the parties hereto, each of which shall be deemed an original and all of which together will constitute one and the same instrument. Delivery of an executed counterpart of a signature page to this Agreement by facsimile or other electronic delivery shall be effective as delivery of a mutually executed counterpart to this Agreement.

Section 8.11 Titles and Headings. The titles, captions and table of contents in this Agreement are for reference purposes only, and shall not in any way define, limit, extend or describe the scope of this Agreement or otherwise affect the meaning or interpretation of this Agreement.

Section 8.12 Entire Agreement. This Agreement (including the schedules and exhibits attached hereto), the Parent Confidentiality Agreement and the Company Confidentiality Agreement constitute the entire agreement among the parties with respect to the matters covered hereby and supersedes all previous written, oral or implied understandings among them with respect to such matters.

Section 8.13 Severability. The invalidity of any portion hereof shall not affect the validity, force or effect of the remaining portions hereof. If it is ever held that any restriction hereunder is too broad to permit enforcement of such restriction to its fullest extent, such restriction shall be enforced to the maximum extent permitted by law.

-90-

Section 8.14 No Strict Construction. Each of the parties hereto acknowledges that this Agreement has been prepared jointly by the parties hereto, and shall not be strictly construed against any party.

Section 8.15 Specific Performance. Each of the parties acknowledges that the rights of each party to consummate the transactions contemplated hereby are unique and recognize and affirm that in the event of a breach of this Agreement by any party, money damages may be inadequate and the non-breaching party may have no adequate remedy at law. Accordingly, the parties agree that such non-breaching party shall have the right, in addition to any other rights and remedies existing in their favor at law or in equity, to enforce their rights and the other party's obligations hereunder by an action or actions for specific performance, injunctive and/or other equitable relief (without posting of bond or other security).

Section 8.16 Failure or Indulgence not Waiver. No failure or delay on the part of any party hereto in the exercise of any right hereunder shall impair such right or be construed to be waiver of, or acquiescence in, any breach of any representation, warranty or agreement herein, nor shall any single or partial exercise of any such right preclude any other or further exercise thereof or any other right. No provision of this Agreement may be waived except by an instrument in writing executed by the party or parties, as applicable, against whom the waiver is to be effective.

Section 8.17 Amendments. Subject to applicable law, this Agreement may be amended by the parties hereto by action taken by or on behalf of their respective Boards of Directors (or similar governing body) at any time prior to the Closing. This Agreement (including the provisions of this Section 8.17) may not be amended or modified except by an instrument in writing signed on behalf of the parties hereto.
