Each holder of Dissenting Shares (“Dissenting Shareholder”) who, pursuant to the provisions of Delaware Law, becomes entitled to payment of the fair value for shares of Target Capital Stock, shall receive payment therefore (but only after the fair value therefore shall have been agreed upon or finally determined pursuant to such provisions).

(c) The Stockholders’ Agent Expense Escrow shall be transferred at Closing by Acquiror to the Escrow Agent for deposit in a separate escrow account pursuant to the terms of a separate escrow agreement (the “Designated Escrow Agreement”) to be entered into between the Stockholders’ Agent and the Escrow Agent prior to Closing (it being understood that the Security Holders shall be named therein as express third-party beneficiaries). The Designated Escrow Agreement shall be funded solely with cash and not with Acquiror Common Stock. The Stockholders’ Agent Expense Escrow shall be available solely to reimburse Stockholders’ Agent for any costs and expenses reasonably and actually incurred by Stockholders’ Agent in connection with the administration of its duties and the fulfillment of its obligations hereunder, and shall be released to Security Holders and Stockholders’ Agent, as the case may be, pursuant to the terms of this Section 2.10(c) and the Designated Escrow Agreement. The full amount of any portion of the Stockholders’ Agent Expense Escrow that remains in escrow and has not been released to Stockholders’ Agent as of the Final Escrow Release Date shall be released to Security Holders on such date; provided, that if, as of the Final Escrow Release Date, there are any pending but unresolved indemnification claims of any Acquiror Indemnified Persons, then all amounts shall remain in escrow and remain available for release to Stockholders’ Agent until all indemnification claims have been finally resolved and Stockholders’ Agent has been reimbursed in full for all costs and expenses reasonable and actually incurred in connection with the administration of its duties and fulfillment of its obligations hereunder. Any amount payable to a Security Holder pursuant to this Section 2.10(c) and the Designated Escrow Agreement shall be equal to such Security Holder’s Escrow Pro Rata Share of such amount. Any amounts released from the Stockholders’ Agent Expense Escrow

- 20 -

shall be distributed to the Security Holders directly by the Escrow Agent or Paying Agent. Neither the Acquiror nor Target shall have any liability related to the use, distributions or release of any of the Stockholders’ Agent Expense Escrow. The Stockholders’ Agent or the Security Holders shall incur all costs and fees of, or associated with the use of, the Stockholders’ Agent Expense Escrow, shall be responsible for any actions taken or failed to be taken by the Stockholders’ Agent in connection with the Stockholders’ Agent Expense Escrow, and the use of the Stockholders’ Agent Expense Escrow shall in no way impact or increase any obligations or liability of the Acquiror or Target.

such holder, as the case may be, (i) an amount in cash equal to the cash portion of the Merger Consideration (including, if applicable, any cash in lieu of fractional shares of Acquiror Common Stock) that such holder has the right to receive pursuant to this Section 2, less the amount of such portion of the Merger Consideration to be transferred to the Escrow Agent by Acquiror as part of the Indemnification Escrow, Purchase Price Adjustment Escrow and Stockholders’ Agent Expense Escrow on such holder’s behalf pursuant to Section 2.10 and (ii) the number of shares of Acquiror Common Stock that such holder has the right to receive pursuant to this Section 2. The Certificate so surrendered shall forthwith be canceled. Until so surrendered, each outstanding Certificate that prior to the Effective Time represented shares of Common Stock, Series A Preferred Stock, Series B Preferred Stock or Target Restricted Stock, as applicable, will be deemed from and after the Effective Time, for all corporate purposes other than the payment of dividends, to evidence the right to receive the portion of the Merger Consideration which shall be payable by Acquiror for each share of such Common Stock, Series A Preferred Stock, Series B Preferred Stock and Target Restricted Stock, as applicable.

(a) At least two (2) Business Days but no longer than four (4) Business Days prior to the Closing Date, Target shall deliver to Acquiror a certificate of Target’s Chief Financial Officer setting forth Target’s good faith estimate of (1) the Working Capital as of the Closing Date (the “Estimated Working Capital”), (2) the Net Debt as of the Closing Date (the “Estimated Net Debt”) and (3) the Transaction Expenses (the “Estimated Transaction Expenses”), reflecting in each case Target’s reasonably detailed calculations of each of the components of such Working Capital, Net Debt and Transaction Expenses amounts and the aggregate amounts thereof. The calculation of the Estimated Working Capital, Estimated Net Debt and Estimated Transaction Expenses shall be in the form consistent with Section 2.15(f) of the Target Disclosure Schedule.

(b) In the event that the Estimated Working Capital is a lesser amount than the Target Working Capital, the Merger Consideration shall be adjusted downward by the difference of the amount by which the Target Working Capital exceeds the Estimated Working Capital. In the event that the Estimated Working Capital is a greater amount than the Target Working Capital, the Merger Consideration shall be adjusted upward by the difference of the amount by which the Estimated Working Capital exceeds the Target Working Capital. In the event that the Estimated Net Debt is a positive amount, then the Merger Consideration shall be adjusted upward by such amount. In the event that the Estimated Net Debt is a negative amount, then the Merger Consideration shall be adjusted downward by the absolute value of such amount. The Merger Consideration shall be adjusted downward by the amount of the Estimated Transaction Expenses. The adjustments, if any, referred to in this Section 2.15(b) are referred to herein as the “Closing Adjustment Amounts.”

(c) Within ninety (90) days after the Closing Date, Acquiror shall prepare and deliver to Stockholders’ Agent a certificate of Acquiror’s Chief Financial Officer (the “Closing Certificate”) setting forth Acquiror’s good faith determination of (i) the Working Capital as of the Closing Date, (ii) the Net Debt as of the Closing Date and (iii) the Transaction Expenses, reflecting in each case Acquiror’s reasonably detailed calculation of each of the components of such Working Capital, Net Debt and Transaction Expenses amounts and the aggregate amounts thereof. Acquiror’s calculations of Working Capital, Net Debt and Transaction Expenses shall be in the form consistent with Section 2.15(f) of the Target Disclosure Schedule.

(d) The Stockholders’ Agent shall have thirty (30) days from the date on which it receives the Closing Certificate to raise any objection(s) to the calculations set forth therein by delivering a written notice to Acquiror setting forth such objection(s) in reasonable

- 23 -

detail (the “Disputed Items”). In the event that Stockholders’ Agent does not deliver any such objection(s) with respect to the calculations set forth in the Closing Certificate within such thirty (30) day period, then the calculations set forth in the Closing Certificate shall be deemed final. In the event that any such objection(s) are so delivered, then the calculations set forth in the Closing Certificate shall be deemed not final and Acquiror and Stockholders’ Agent shall attempt, in good faith, to resolve the Disputed Items and, if they are unable to resolve all of the Disputed Items within thirty (30) days after the date of such Disputed Items notice, shall, within five (5) Business Days thereafter (or such earlier date as mutually agreed), submit the Disputed Items to the Independent Accounting Firm. Acquiror and Stockholders’ Agent shall provide to the Independent Accounting Firm all work papers and back-up materials relating to the Disputed Items reasonably requested by the Independent Accounting Firm and to the extent available to Acquiror or its Representatives or Stockholders’ Agent or its Representatives. The Acquiror and Stockholders’ Agent shall be afforded the opportunity to present to the Independent Accounting Firm any material related to the Disputed Items and to discuss the issues with the Independent Accounting Firm. The determination by the Independent Accounting Firm, as set forth in a notice that Stockholders’ Agent and Acquiror shall cause the Independent Accounting Firm to deliver to Acquiror and Stockholders’ Agent within thirty (30) days after the submission of the Disputed Items to the Independent Accounting Firm, shall be final, binding and conclusive on Acquiror, Stockholders’ Agent and all Security Holders. The fees and expenses of the Independent Accounting Firm shall be split equally between Acquiror, on the one hand, and the Security Holders (through payment from the Stockholder Agent Expense Escrow) on the other hand. The Working Capital, Net Debt and Transaction Expenses amounts reflected in the Closing Certificate, as revised to reflect the resolution of any and all Disputed Items in accordance with this Section 2.15(d), shall be deemed to be the “Final Working Capital,” “Final Net Debt” and “Final Transaction Expenses”, as applicable.

(e) At such time as the calculations set forth in the Closing Certificate shall become final in accordance with Section 2.15(d), the Estimated Working Capital shall be compared to the Final Working Capital, the Estimated Net Debt shall be compared to the Final Net Debt, and the Estimated Transaction Expenses shall be compared to the Final Transaction Expenses, and Stockholders’ Agent and Acquiror shall make or cause to be made whatever payments are necessary, if any, to reflect the increase or decrease in the Merger Consideration that would have resulted if the Estimated Working Capital, Estimated Net Debt and Estimated Transaction Expenses instead had equaled the Final Working Capital, Final Net Debt and Final Transaction Expenses, respectively. Any payment to be made pursuant to this Section 2.15(e) shall be made, within five (5) Business Days after the date that the Final Working Capital, Final Net Debt and Final Transaction Expenses are finally determined pursuant to Section 2.15(d), with any payments to be made to (A) Acquiror to be made by Stockholders’ Agent and Acquiror causing the Escrow Agent to release to Acquiror the applicable amount (y) initially from the Purchase Price Adjustment Escrow, and (z) thereafter from the Indemnification Escrow, without regard to the Limitation set forth in Section 9.2(d), if the Purchase Price Adjustment Escrow is insufficient to provide full payment to Acquiror as required by this Section 2.15(e) and (B) Security Holders to be made by Acquiror in cash to each Security Holder in an amount equal to its Escrow Pro Rata Share of such payments. The Stockholders’ Agent and Acquiror shall cause the Escrow Agent to release any amounts not required to be paid to Acquiror pursuant to this Section 2.15(e) and remaining in the Purchase Price Adjustment Escrow, if any, to Security

- 24 -

Holders, in amounts equal to their respective Escrow Pro Rata Shares, promptly after giving effect to any payment required to be made to Acquiror pursuant to this Section 2.15(e).

(f) Section 2.15(f) of the Target Disclosure Schedule contains a reasonably detailed example of the calculations to be made pursuant to this Section 2.15.

6.13 Directors’ and Officers’ Indemnification and Insurance.

(a) Acquiror agrees that all rights to indemnification and related rights to advancement of expenses on the part of each person who at the Effective Time is a current or former director, officer, employee or agent of Target or any Target Related Business, including all such rights existing pursuant to any written agreement between any such person and Target or any Target Related Business in effect on the Agreement Date (copies of which have been delivered to Acquiror), Delaware Law or as provided in the Target Organizational Documents or the Target Related Business Organizational Documents, shall survive the Merger and shall continue in full force and effect until ninety (90) days after the expiration of the longest applicable statute of limitation.

Without limitation of the foregoing, in the event any such person is or becomes involved in any such capacity in any action, proceeding or investigation in connection with any actual or alleged action, inaction, state of affairs or other matter, including any matter related to the transactions contemplated by this Agreement, occurring on or prior to the Effective Time, Acquiror shall (or shall cause the Surviving Corporation to) pay such person’s reasonable fees and other expenses of counsel selected by such person (including the cost of any investigation, preparation and settlement) incurred in connection therewith promptly after statements therefor are received by Acquiror, except to the extent of any claims that are finally determined by a court of competent jurisdiction to have resulted from the gross negligence, willful misconduct or fraud of such indemnified party. Acquiror shall be entitled to participate in the defense of any such action or proceeding, and counsel selected by the indemnified person shall, to the extent consistent with their professional responsibilities, cooperate with Acquiror and any counsel designated by Acquiror. Acquiror shall pay all reasonable fees and expenses, including fees and expenses of counsel, that may be incurred by any indemnified person in successfully enforcing the indemnity and other obligations provided for in this section.

- 54 -

9.4 Objections to Claims.

(a) For a period of thirty (30) days from and after receipt by Stockholders’ Agent of any Officer’s Certificate from Acquiror, Acquiror shall take no action regarding the portion of the Indemnification Escrow hereof equal to the amount of Damages set forth in such Officer’s Certificate unless it shall have received written authorization from Stockholders’ Agent that it does not object to the release by Escrow Agent of such portion of the Indemnification Escrow to Acquiror. After the expiration of such thirty (30) day period, Stockholders’ Agent shall not object to the release to Acquiror of the portion of the Indemnification Escrow requested to be released from escrow in such Officer’s Certificate delivered pursuant to Section 9.3 hereof, provided that no such release may be made if Stockholders’ Agent shall object in a written statement to the claim made in such Officer’s Certificate, and such statement shall have been delivered to Acquiror prior to the expiration of such thirty (30) day period.

(b) For a period of thirty (30) days from and after receipt by Acquiror of any Officer’s Certificate from Stockholders’ Agent, Stockholders’ Agent shall take no action regarding the amount of Damages set forth in such Officer’s Certificate. After the expiration of such thirty (30) day period, Acquiror shall be deemed to have agreed to pay all such Damages, provided that it has not objected in a written statement to the claim made in such Officer’s Certificate, and such statement shall have been delivered to Stockholders’ Agent prior to the expiration of such thirty (30) day period.

(c) In case a party shall object in writing to any claim or claims made in any Officer’s Certificate, the other party shall have thirty (30) days to respond in a written statement delivered to the party that delivered the Officer’s Certificate. If after such thirty (30) day period there remains a dispute as to any claims, Stockholders’ Agent and Acquiror shall attempt in good faith for thirty (30) days to agree upon the rights of the respective parties with respect to each of such claims. If Stockholders’ Agent and Acquiror agree, a memorandum setting forth such agreement shall be prepared and signed by Acquiror and Stockholders’ Agent and the parties shall take such actions as may be required to promptly give effect to such agreement.

9.5 Resolution of Conflicts. If no agreement can be reached after good faith negotiation between the parties pursuant to Section 9.4 with respect to the amount of Damages

- 64 -

that are subject to a claim for indemnification, then either Acquiror or Stockholders’ Agent may initiate formal legal action, subject to the terms and conditions of this Agreement, to resolve such dispute. The decision of the court as to the validity and amount of any claim in such Officer’s Certificate shall be binding and conclusive upon the parties to this Agreement, and notwithstanding anything in Section 9 hereof, the parties shall act in accordance with such decision.

9.6 Third-Party Claims. In the event an Indemnified Person becomes aware of a third party claim (a “Third Party Claim”) which such Indemnified Person believes in good faith may result in a demand for indemnification, the Indemnified Person shall promptly notify the Indemnifying Person of the Third Party Claim in writing. No delay or failure in providing such notice shall affect an Indemnified Persons’ rights hereunder, unless (and then only to the extent that) the Indemnifying Person is materially prejudiced thereby. The Indemnifying Person shall be entitled to participate in the defense of the Third Party Claim and, if it so chooses, to assume the defense thereof at its own expense with counsel selected by such Indemnifying Person and reasonably acceptable to the Indemnified Person, provided, that, the Indemnifying Person gives written notice to the Indemnified Person of its election to participate in or to assume the defense of the Third Party Claim within ten (10) Business Days after the Indemnifying Person receives the written notice of such claim from the Indemnified Person; provided, however, that the Indemnifying Person shall not be entitled to assume the defense of any Third Party Claim in which, either directly or indirectly, (i) criminal liability is involved, (ii) an injunction or equitable relief is being sought against the Indemnified Person that would be material to the operation of its business, or (iii) the potential Damages would reasonably be expected to exceed the amount of the Indemnification Escrow (or any portion thereof that remains in escrow), provided that the Indemnified Person assumes the defense of such Third Party Claim and defends such Third Party Claim in a manner that is substantially similar in all material respects to the manner in which it would have defended such claim if it were not entitled to the benefit of this Section 9 (with the reasonable expenses, and any settlement entered into in accordance with this Section 9.6, constituting Damages hereunder to the extent the Indemnified Person is entitled to recover therefore under the terms hereof). If the Indemnifying Person assumes the defense of a Third Party Claim, the Indemnifying Person may not consent to the entry of any judgment or enter into any settlement with respect to the Third Party Claim without the prior written consent of the Indemnified Person (not to be unreasonably withheld, conditioned or delayed) if (i) such judgment or settlement does not include as an unconditional term thereof the giving by each claimant or plaintiff to the Indemnified Person of a full release from all liability in respect to such Third Party Claim, (ii) such judgment or settlement would result in the finding or admission of any violation of any Legal Requirement by the Indemnified Person or the rights of any person, (iii) the sole relief provided is anything other than monetary damages or (iv) as a result of such judgment or settlement, injunctive or other equitable relief would be imposed against the Indemnified Person or such judgment or settlement would reasonably be expected to interfere with or materially and adversely affect the business, operations or assets of the Indemnified Person. The Indemnified Person will cooperate, at the expense of the Indemnifying Person, as the Indemnifying Person may reasonably request, in investigating, defending and, subject to the terms set forth above, settling such Third Party Claim. If the Indemnifying Person elects not to assume the defense of a Third Party Claim, is not permitted to assume the defense of such Third Party Claim or fails to notify the Indemnified Person of its election to participate in or assume the defense of such Third Party Claim as herein

- 65 -

provided, the Indemnified Person may pay, compromise, settle or defend such Third Party Claim at the sole cost and expense of the Indemnifying Person if the Indemnifying Person is determined to be liable to the Indemnified Person hereunder. Notwithstanding the foregoing, if the Indemnifying Person is contesting any claims in good faith, or would, but for its inability to assume the defense of such claims pursuant to this Section 9.6, be contesting the claims in good faith, then the Indemnified Person shall not pay or settle any such claims without the prior written consent of the Indemnifying Person, which shall not be unreasonably withheld, conditioned or delayed.

9.7 Tax Effects of Indemnification Payments. All amounts paid pursuant to Section 9 of this Agreement shall be treated for all Tax purposes as adjustments to the aggregate Merger Consideration.

9.8 Tax Indemnification.

(a) Indemnification of Acquiror. In addition to the indemnification obligations set forth in Section 9.2 above (but without duplication as to indemnified amounts and subject to the Cap), the Security Holders shall jointly and severally indemnify the Acquiror Indemnified Persons, out of the then-available amount of the Indemnification Escrow that remains in escrow, and hold them harmless from and against any Damages resulting from or arising out of (a) all Taxes (or the non-payment thereof) of Target for all taxable periods ending on or before the Closing Date and the portion through the end of the Closing Date for any taxable period that includes (but does not end on) the Closing Date (“Pre-Closing Tax Period”), (b) all Taxes of any member of an affiliated, consolidated, combined or unitary group of which Target (or any predecessor of Target) is or was a member on or prior to the Closing Date, including pursuant to Treasury Regulation §1.1502-6 or any analogous or similar state, local, or non-U.S. law or regulation, and (c) any and all Taxes of any Person (other than Target) imposed on Target as a transferee or successor, by contract or pursuant to any applicable law, which Taxes relate to an event or transaction occurring before the Closing; provided, however, that in the case of clauses (a), (b), and (c) above, Security Holders shall be liable only to the extent that such Taxes exceed the amount, if any, taken into account in the calculation of Final Working Capital; and provided further that no indemnification shall be provided for any Taxes associated with the classification for U.S. federal, state and local Tax purposes of the physicians identified in Section 3.20(i) of the Target Disclosure Schedule. The Security Holders shall reimburse Acquiror, out of the then-available amount of the Indemnification Escrow that remains in escrow, for any Taxes that are the responsibility of Security Holders within sixty (60) Business Days after payment of such Taxes by Acquiror or Target. The Limitation shall not apply with respect to any Damages arising from the matters set forth in this Section 9.8.

(b) Straddle Period. In the case of any taxable period that includes (but does not end on) the Closing Date (a “Straddle Period”), the amount of any Taxes based on or measured by income or receipts of Target for the Pre-Closing Tax Period shall be determined based on an interim closing of the books as of the close of business on the Closing Date and the amount of other Taxes of Target for a Straddle Period that relates to the Pre-Closing Tax Period shall be deemed to be the amount of such Tax for the entire taxable period multiplied by a fraction the numerator of which is the number of days in the taxable period ending on the Closing Date and the denominator of which is the number of days in such Straddle Period.

- 66 -

(c) Tax Notifications. Acquiror shall notify the Stockholders’ Agent in writing, and in reasonable detail, within fifteen (15) Business Days of the receipt by Acquiror or any Affiliate of Acquiror (including Target after the Closing Date) of written notice of any inquiries, claims, assessments, audits or similar events with respect to Taxes for which indemnification may be sought under this Section 9 (any such inquiry, claim, assessment, audit or similar event, a “Tax Matter”); provided, that delay or failure to give such notification shall not affect the indemnification provided by this Section 9, except to the extent such delay or failure prejudices the Stockholders’ Agent’s ability to contest such Tax Matter. For Tax Matters in which only one or more Pre-Closing Tax Periods are at issue, the Stockholders’ Agent shall have the exclusive authority to represent the interests of the Seller Indemnified Persons with respect to any such Tax Matter and shall have the sole right to extend or waive the statute of limitations with respect to such Tax Matter, including responding to inquiries, filing Returns and settling audits or lawsuits; provided, that the Stockholders’ Agent shall not enter into any settlement of or otherwise compromise any Tax Matter that adversely affects the Tax liability of Acquiror or Target for any Post-Closing Tax Period, including the post-Closing portion of any Straddle Tax Period, without the prior written consent of Acquiror, which consent shall not be unreasonably withheld. The Stockholders’ Agent shall keep Acquiror fully and timely informed with respect to the commencement, status and nature of any Tax Matter. The Stockholders’ Agent and Acquiror shall jointly represent the interests of Target with respect to all Tax Matters in which a Straddle Period is at issue or in which one or more Pre-Closing Tax Periods are at issue and one or more Post-Closing Tax Periods are at issue.

9.9 Limitation on Liability of Security Holders. Notwithstanding anything to the contrary contained in this Agreement, any letter of transmittal or otherwise, under no circumstance whatsoever shall any Security Holder’s liability to Acquiror, its Affiliates or their respective Representatives in connection with or as a result of this Agreement or the transactions contemplated hereby, including with respect to fraud or intentional misrepresentation, exceed the aggregate amount of Merger Consideration received by such Security Holder in connection herewith.

9.10 Exclusive Remedy. This Section 9 shall be the exclusive remedy following the Closing for any matters in connection with this Agreement and the transactions contemplated hereby except in connection with specific performance as provided by Section 10.8 of this Agreement. Any claim pursuant to Sections 9.2(b) and 9.8 shall be satisfied solely from the then-available amount of the Indemnification Escrow that remains in escrow except to the extent (a) such amount is insufficient to cover Damages with respect thereto and relates to a claim for breach of a Fundamental Rep or (b) such amount is insufficient to cover Damages with respect thereto and relates to a claim for fraud or intentional misrepresentation. Any liability of Security Holders that is not required to be satisfied from the then-available amount of the Indemnification Escrow shall be on a several, and not joint, basis; provided, however, that no Security Holder shall be liable for the fraud or intentional misrepresentation of any other Person (other than of Target, for which such Security Holders shall be liable on a several, and not joint, basis but subject to Section 9.9).

9.11 WAIVER. NOTWITHSTANDING ANYTHING TO THE CONTRARY CONTAINED IN THIS AGREEMENT, INCLUDING IN THE DEFINITION OF DAMAGES, THE PARTIES TO THIS AGREEMENT EXPRESSLY WAIVE AND FOREGO (ON BEHALF

- 67 -

OF THEMSELVES AND EACH OF THE ACQUIROR INDEMNIFIED PERSONS AND THE SELLER INDEMNIFIED PERSONS, AS APPLICABLE) ANY RIGHT TO RECOVER PUNITIVE DAMAGES, LOSS OF OR DIMINUTION IN VALUE DAMAGES, DAMAGES BASED ON A MULTIPLE OF EARNINGS, AND ANY REMOTE OR SPECULATIVE DAMAGES, IN EACH CASE IN ANY ARBITRATION, LAWSUIT, LITIGATION OR OTHER PROCEEDING ARISING OUT OF OR RESULTING FROM ANY CONTROVERSY OR CLAIM ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY, WHETHER OR NOT THE POSSIBILITY OF SUCH HAS BEEN DISCLOSED IN ADVANCE OR COULD HAVE BEEN REASONABLY FORESEEN, EXCEPT FOR ANY SUCH DAMAGES THAT MAY BE AWARDED IN CONNECTION WITH A THIRD-PARTY CLAIM FOR WHICH A PARTY IS ENTITLED TO BE INDEMNIFIED HEREUNDER.

9.12 Indemnification Related to SEC Filings; Registration Statement; Stock Sale Plan Agreement.

(a) Acquiror shall indemnify and hold harmless each Acquiror Common Stock Recipient (the “Acquiror Common Stock Indemnified Party”) from and against any and all Damages (without regard to the waiver with respect to limitations on such Damages contained in Section 9.11) to the extent resulting from or arising out of or based upon (i) any untrue or alleged untrue statement of a material fact contained in any Registration Statement or Prospectus or any amendment thereof or supplement thereto or arising out of or based upon any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as the same are made in reliance on and in conformity with the information furnished in writing to Acquiror by such Acquiror Common Stock Indemnified Party expressly for use therein, (ii) any breach by Acquiror of its obligations under Section 2.7 and (iii) any breach by Acquiror of its obligations under the Stock Sale Plan Agreement.

(b) Each Acquiror Common Stock Indemnified Party hereunder shall (i) give prompt written notice to Acquiror of any third-party claim with respect to which it seeks indemnification and (ii) permit Acquiror to assume the defense of such third-party claim with counsel reasonably satisfactory to the Acquiror Common Stock Indemnified Party. Failure to so notify the Acquiror shall not relieve it from any liability that it may have to an Acquiror Common Stock Indemnified Party except to the extent that the Acquiror is materially and adversely prejudiced thereby. Acquiror shall not be subject to any liability for any settlement made by the Acquiror Common Stock Indemnified Party without its consent (but such consent will not be unreasonably withheld, conditioned or delayed). Acquiror shall not be obligated to pay the fees and expenses of more than one counsel (in addition to one local counsel) for all Acquiror Common Stock Indemnified Parties indemnified hereunder by such Acquiror with respect to such third-party claim (and all other claims arising out of the same circumstances), unless in the reasonable judgment of any Acquiror Common Stock Indemnified Party, there may be one or more legal or equitable defenses available to such Acquiror Common Stock Indemnified Party which are in addition to or may conflict with those available to another Acquiror Common Stock Indemnified Party with respect to such third-party claim, in which case each such Acquiror Common Stock Indemnified Party shall be entitled to use separate counsel. Acquiror shall not consent to the entry of any judgment or enter into or agree to any settlement

- 68 -

relating to such third-party claim unless such judgment or settlement imposes no ongoing obligations on any such Acquiror Common Stock Indemnified Party and includes as an unconditional term the giving, by all relevant claimants and plaintiffs involved in such third-party claim, a release, reasonably satisfactory in form and substance to such Acquiror Common Stock Indemnified Party, from all liabilities in respect of such third-party claim. No Acquiror Common Stock Indemnified Party shall be liable hereunder for any amount paid or payable or incurred pursuant to or in connection with any judgment entered or settlement effected without the consent of such Acquiror Common Stock Indemnified Party.

This Agreement may be executed in one or more counterparts, all of which shall be considered one and the same agreement and shall become effective when one or more counterparts have been signed by each of the parties and delivered to the other parties, it being understood that all parties need not sign the same counterpart and such counterparts may be delivered by the parties hereto via facsimile or electronic communication.

10.3 Entire Agreement; Nonassignability; Parties in Interest. This Agreement and the documents and instruments and other agreements specifically referred to herein or delivered pursuant hereto, including the exhibits and schedules hereto, and the Target Disclosure Schedule, and the letter agreement, dated September 23, 2011, between Target and Acquiror, (a) together constitute the entire agreement among the parties with respect to the subject matter hereof and supersede all prior agreements and understandings, both written and oral, among the parties with respect to the subject matter hereof except for the Confidentiality Agreement, which shall continue in full force and effect, and shall survive any termination of this Agreement or the Closing, in accordance with its terms; and (b) are not intended to confer upon any other Person any rights or remedies hereunder (other than any Person entitled to (i) insurance under Section 6.13, (ii) indemnification under Section 9, (iii) be paid Transaction Expenses pursuant to Section 6.20, (iv) as an Acquiror Common Stock Recipient, the benefit of Acquiror’s performance of its obligations under Section 2.7, (v) indemnification under Section 9.12 or (vi) distributions of the Stockholders’ Agent Expense Escrow pursuant to Section 2.10(c), the Indemnification Escrow pursuant to Section 9.1 and the Purchase Price Adjustment Escrow pursuant to Section 2.15(e), each of which shall be an express third-party beneficiary for

- 70 -

purposes of such sections) and shall not be assigned by operation of law or otherwise without the written consent of the other party.

10.4 Severability. In the event that any provision of this Agreement or the application thereof becomes or is declared by a court of competent jurisdiction to be illegal, void or unenforceable, the remainder of this Agreement will continue in full force and effect and the application of such provision to other persons or circumstances will be interpreted so as reasonably to effect the intent of the parties hereto. The parties further agree to replace such void or unenforceable provision of this Agreement with a valid and enforceable provision that will achieve, to the extent possible, the economic, business and other purposes of such void or unenforceable provision.

10.5 Remedies Cumulative. Except as otherwise provided herein, any and all remedies herein expressly conferred upon a party will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by law or equity upon such party, and the exercise by a party hereto of any one remedy will not preclude the exercise of any other remedy.

10.6 Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware without reference to such state’s principles of conflicts of law. The parties hereto hereby irrevocably submit to the exclusive jurisdiction of the courts of the State of Delaware and the Federal courts of the United States of America located within the State of Delaware, in respect of the interpretation and enforcement of the provisions of this Agreement and of the documents referred to in this Agreement, and in respect of the transactions contemplated hereby and thereby (including resolution of disputes under Section 9.4), and hereby waive, and agree not to assert, as a defense in any action, suit or proceeding for the interpretation or enforcement hereof or thereof, that it is not subject thereto or that such action, suit or proceeding may not be brought or is not maintainable in said courts or that the venue thereof may not be appropriate or that this Agreement or any such document may not be enforced in or by such courts, and the parties hereto irrevocably agree that all claims with respect to such action or proceeding shall be heard and determined in such a Delaware State or Federal court. The parties hereby consent to and grant any such court jurisdiction over the person of such parties and over the subject matter of such dispute and agree that mailing of process or other papers in connection with any such action or proceeding in the manner provided in Section 10.1 or in such other manner as may be permitted by applicable Legal Requirements, shall be valid and sufficient service thereof. With respect to any particular action, suit or proceeding, venue shall lie solely in the State of Delaware.

10.7 Rules of Construction. The parties hereto agree that they have been represented by counsel during the negotiation, preparation and execution of this Agreement and, therefore, waive the application of any law, regulation, holding or rule of construction providing that ambiguities in an agreement or other document will be construed against the party drafting such agreement or document.

10.8 Specific Enforcement. Each of the parties acknowledges and agrees that there would be irreparable harm, damages would be difficult to determine and there would not be any adequate remedy at law in the event that any of the provisions of this Agreement were not performed by the parties in accordance with their specific terms or were otherwise breached.

- 71 -

Accordingly each of the parties agrees that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement, this being in addition to any other remedy to which the parties are entitled at law or in equity.

11. Stockholders’ Agent.

(a) Each holder of Target Capital Stock and Target Restricted Stock (by his, her or its execution of the Written Consent or Letter of Transmittal), authorizes Stockholders’ Agent to act as agent and attorney-in-fact for and on behalf of the Security Holders and to take all actions necessary or appropriate in the judgment of Stockholders’ Agent with respect to an matter related to this Agreement or the Escrow Agreement, including all actions required or permitted to be taken by Stockholders’ Agent under this Agreement. Such agency may be changed by the holders of a majority in interest of the Escrow Pro Rata Shares upon not less than 10 days’ prior written notice to Acquiror. Stockholders’ Agent may resign as such upon 10 days’ prior written notice to Acquiror and Target or the Surviving Corporation (as applicable). In the event of such resignation, a replacement Stockholders’ Agent shall promptly be selected by the holders of a majority in interest of the Escrow Pro Rata Shares, and Stockholders’ Agent’s resignation shall not become effective until the earlier of (x) the time at which such replacement stockholders’ agent has been selected and (y) 45 days after the date on which Stockholders’ Agent provided written notice of such resignation to Acquiror and Target or the Surviving Corporation (as applicable). In such an event, Stockholders’ Agent shall (i) reasonably cooperate in order to ensure a timely transition of responsibilities and records to the newly-selected stockholders’ agent, (ii) no longer be entitled to administer this Agreement, the Escrow Agreement or the Designated Escrow Agreement from and after the effective time of its replacement (and shall take whatever actions are reasonably necessary to remove itself as a party thereto in substitution for the newly-selected stockholders’ agent) and (iii) only be entitled to expense reimbursement under Section 2.10(c) and the Designated Escrow Agreement for costs and expenses incurred through the effective time of its resignation. The newly-selected stockholders’ agent shall become the Stockholders’ Agent for all purposes of this agreement, the Escrow Agreement and the Designated Escrow Agreement, and shall perform the duties and obligations of the Stockholders’ Agent hereunder and thereunder, from and after such effective time in accordance with the terms hereof and thereof.

(b) No bond shall be required of Stockholders’ Agent. Stockholders’ Agent shall receive $50,000 for its services, which shall be payable by Target within three (3) Business Days after the date hereof to an account specified by Stockholders’ Agent to Target. Notices or communications to or from Stockholders’ Agent shall constitute notice to or from each of the Security Holders.

(c) The Stockholders’ Agent agrees to perform such duties and only such duties as are specifically set forth in this Agreement and no implied covenant covenants or obligations shall be read into this Agreement against Stockholders’ Agent. The Stockholders’ Agent shall not be liable for any act done or omitted hereunder as Stockholders’ Agent while acting without gross negligence, bad faith or fraud and any act done or omitted pursuant to the advice of counsel shall be conclusive evidence of the absence of gross negligence, bad faith or fraud. In no event shall Stockholders’ Agent have (i) any duty or obligation to initiate, defend or

- 72 -

compromise any claim or (ii) be required to incur any expenses in connection with the performance of its duties hereunder if the amount of such expenses are (together with the amount of all expenses previously incurred by Stockholders’ Agent), in the good faith judgment of Stockholders’ Agent, reasonably likely to exceed the Stockholders’ Agent Expense Escrow. Each holder of Target Capital Stock shall severally indemnify and hold Stockholders’ Agent harmless against any loss, liability or expense (including reasonable attorneys fees) incurred by Stockholders’ Agent and arising out of or in connection with the acceptance or administration of his duties hereunder, except in each case to the extent arising out of the gross negligence, bad faith or fraud of Stockholders’ Agent.

(d) The parties shall provide Stockholders’ Agent with reasonable access to information about Target and Target Related Businesses and the reasonable assistance of Target’s and Target Related Businesses’ officers and employees for purposes of performing its duties and exercising its rights hereunder, provided that Stockholders’ Agent shall treat confidentially and not disclose any nonpublic information from or about Target to anyone (except on a need-to-know basis to individuals who agree to treat such information confidentially).

(e) Acquiror acknowledges that Stockholders’ Agent may have a conflict of interest with respect to its duties as Stockholders’ Agent, and in such regard Stockholders’ Agent has informed Acquiror that it will act in the best interests of the Security Holders.

(f) In all matters related to this Section 11, Stockholders’ Agent shall be the only party entitled to assert the rights of the Security Holders. A decision, act, consent or instruction of Stockholders’ Agent shall constitute a decision of all Security Holders and shall be final, binding and conclusive upon each such Security Holder, and Acquiror may rely upon any decision, act, consent or instruction of Stockholders’ Agent as being the decision, act, consent or instruction of each and every such Security Holder. Acquiror is hereby relieved from any liability to any Person for any acts done by them in accordance with such decision, act, consent or instruction of Stockholders’ Agent.

(g) The Stockholders’ Agent Expense Escrow shall be available to the Stockholders’ Agent solely to reimburse Stockholders’ Agent for any costs and expenses reasonably and actually incurred by Stockholders’ Agent in connection with the administration of its duties and the fulfillment of its obligations hereunder as further described in Section 2.9(c) and in the Designated Escrow Agreement.

(h) Each holder of Target Capital Stock shall promptly provide written notice to Stockholders’ Agent of any change of address of such holder. The Stockholders’ Agent shall maintain reasonable records of disbursements from the Indemnification Escrow, the Purchase Price Adjustment Escrow and the Stockholders’ Agent Expense Escrow and otherwise, which shall be available to Security Holders for inspection upon reasonable request.

- 73 -

This Option Acknowledgment and Release (this “Acknowledgment”) is being delivered to you pursuant to the terms of the Agreement and Plan of Merger, dated as of September 28, 2011 (the “Merger Agreement”), by and among NuVasive, Inc., a Delaware corporation (“Acquiror”), Catamaran Acquisition Corporation, a Delaware corporation and a wholly-owned subsidiary of Acquiror (“Merger Sub”), Impulse Monitoring, Inc., a Delaware corporation (“Company”), and Xxxxxx-Xxxxxxxxx & Co., Inc., a Delaware corporation, in its capacity as the Stockholders’ Agent (the “Stockholders’ Agent”).

Pursuant to the Merger Agreement, at the effective time of the Merger (the “Effective Time”), Merger Sub will merge with and into the Company (the “Merger”) and (i) the outstanding shares of the Company’s capital stock at the Effective Time will be converted into the right to receive the Merger Consideration (as defined in the Merger Agreement) upon the terms and subject to the conditions of the Merger Agreement; and (ii) the outstanding unexpired and unexercised options (the “Company Options”) to purchase shares of the Company’s common stock (“Common Stock”) will become fully vested and automatically converted into the right to receive a cash payment equal on a per share basis to the cash amount that a holder of a share of the Company’s Common Stock would receive less the applicable exercise price per share of such holder’s Company Options, reduced by applicable withholding taxes and subject to certain purchase price adjustments and indemnification obligations under the Merger Agreement (the “Per Share Option Cancellation Payment”).

It is estimated, as of the date of this Acknowledgment, that the per share cash amount is expected to be within a range of approximately $[—] to $[—]. Please note this range is merely an estimate, and is subject to change. Also, please note that a portion of the Per Share Option Cancellation Payment will be set aside, until its release (if at all), in accordance with the terms of the Merger Agreement, an indemnification escrow agreement (the “Escrow Agreement”) and Stockholders’ Agent expense escrow agreement (the “Expense Escrow Agreement”) for the purposes of satisfying certain purchase price adjustments, any claims Acquiror has for indemnification and costs and expenses incurred by the Stockholders’ Agent, as applicable. By signing this Acknowledgment, you hereby agree and acknowledge that your payment may be reduced by these potential adjustments, indemnity claims and Stockholders’ Agent costs and expenses, in each case pursuant to the Merger Agreement, the Escrow Agreement and the Expense Escrow Agreement.

Pursuant to the terms of the Merger Agreement, the Stockholders’ Agent will act as an agent and attorney-in-fact for and on behalf of all stockholders and holders of Company Options in representing the stockholders and the holders of Company Options related to the potential purchase price adjustments and indemnity claims described above, and is authorized to take all actions necessary or appropriate in the judgment of Stockholders’ Agent in connection therewith. By signing this Acknowledgment, the undersigned agrees to the appointment of the Stockholders’ Agent and the use of the Expense Escrow Agreement for the reasonable costs and expenses incurred by the Stockholder’s Agent.

The undersigned understands that the initial cash payment will be made after the closing of the Merger and the execution of this Acknowledgment, and will be payable in accordance with the Company’s regular payroll procedures. Check(s) to which the undersigned is entitled will be issued in the name set forth on Exhibit A hereto and delivered to the address set forth on Exhibit A hereto.

Based on the records of the Company, immediately prior to the Effective Time, you hold the Company Options identified on Exhibit A hereto (the “Holder Options”). By executing this letter, you authorize and instruct the Company to deduct and withhold from the consideration otherwise payable to you pursuant to the Merger Agreement such amounts as it is required to deduct and withhold with respect to the making of such payment under applicable tax law.

IMPORTANT TAX INFORMATION

Under U.S. federal income tax law, a holder whose shares of Stock are surrendered herewith is required to provide such stockholder’s current Taxpayer Identification Number (“TIN”). If such holder is an entity, the TIN is its employer identification number. If such holder is an individual, the TIN is his or her social security number. If the holder does not provide the correct TIN, the holder may be subject to a $50 penalty imposed by the Internal Revenue Service. In addition, reportable payments that are made to such holder may be subject to U.S. federal income tax backup withholding. If withholding results in an overpayment of taxes, a refund from the Internal Revenue Service may be obtained. To prevent backup withholding on any cash payment made to a holder with respect to shares of Stock surrendered in connection with the Merger Agreement, the holder is required to notify Paying Agent of his or her correct TIN by completing the Substitute Form W-9 below and certifying that the TIN provided on Substitute Form W-9 is correct. The box in Part IV of the Substitute Form W-9 may be checked if the payee has not been issued a TIN and has applied for a TIN or intends to apply for a TIN in the near future. If the box in Part IV is checked, the stockholder or other payee must also complete the Certificate of Awaiting Taxpayer Identification Number below in order to avoid backup withholding. Notwithstanding that the box in Part IV is checked and the Certificate of Awaiting Taxpayer Identification Number is completed, Paying Agent will withhold required amounts from all payments made prior to the time a properly certified TIN is provided to Paying Agent.

Certain holders (including, among others, all corporations, limited partnerships and certain foreign holders) are not subject to these backup withholding and reporting requirements. To prevent possible erroneous backup withholding, an exempt payee must enter its correct TIN in Part I in the Substitute Form W-9, write “Exempt” in Part III of such form, and sign and date the Form W-9. In order for a foreign holder to be exempt, that holder must submit an Internal Revenue Service Form W-8BEN, or other applicable Form W-8, signed under penalties of perjury, attesting to that individual’s exempt status. See the enclosed Guidelines for Certification of Taxpayer Identification Number or Substitute Form W-9 for additional instructions.

What to Give Acquiror

United States Holders. A United States holder of Stock is required to give Paying Agent the TIN of the record owner of the shares of Stock being surrendered for payment in connection with the Merger Agreement.

Non-United States Holders. A non-United States holder of Stock is required to represent to Acquiror that it is not a United States Person (as such term is defined in Section 7701(a)(3) of the Internal Revenue Code of 1986, as amended) and provide its name and address on a properly executed Internal Revenue Service Form W-8BEN, or other applicable Form W-8.

The method of delivering Stock certificate(s) is at the option and the risk of the holder. Stock may be surrendered in person or by mail. IF SENT BY MAIL, REGISTERED MAIL, PROPERLY INSURED, WITH RETURN RECEIPT REQUESTED, IS RECOMMENDED.

You should complete one Letter of Transmittal listing all Stock registered in the same name. If any shares of Stock are registered in different ways on several certificates, you will need to complete, sign, and submit as many separate Letters of Transmittal as there are different registrations of certificates.

2. Signatures. The signature (or signatures, in the case of certificates owned by two or more joint holders) on this Letter of Transmittal should correspond exactly with the name(s) as written on the face of Stock certificate(s) surrendered unless the shares described on this Letter of Transmittal have been assigned by the registered holder or holders thereof, in which event this Letter of Transmittal should be signed in exactly the same form as the name(s) of the last transferee(s) indicated on the transfers attached to or endorsed on the certificate(s). If the “Special Issuance Instructions” box is completed, then the signature(s) on this Letter of Transmittal must be guaranteed by an eligible guarantor institution (bank, stockbroker, savings and loan association or credit union with membership in an approved signature guarantee medallion program), pursuant to Rule 17Ad-15 promulgated under the Securities Exchange Act of 1934, as amended, and the person surrendering such certificate(s) must remit to Acquiror the amount of any transfer or other taxes payable by reason of the issuance to a person other than the registered holder(s) of the certificate(s) surrendered, or establish to the reasonable satisfaction of Acquiror that such tax has been paid or is not applicable.

If this Letter of Transmittal is signed by a trustee, executor, administrator, guardian, officer of a corporation, attorney-in-fact or other person acting in a fiduciary or representative capacity, the person signing must give his or her full title in such capacity and enclose appropriate evidence of his or her authority to so act. If additional documents are required by Acquiror, you will be promptly advised by letter.

3. Lost, Stolen or Destroyed Stock Certificates. In the event that any holder is unable to deliver to Paying Agent the Stock certificate(s) representing his, her or its shares of Stock due to the loss or destruction of such certificate(s), such fact should be indicated on the face of this Letter of Transmittal. You will be contacted promptly if a fee and/or additional documentation is required to replace lost, stolen or destroyed stock certificates. Surrenders hereunder regarding such lost certificate(s) will be processed only after such documentation has been submitted to and approved by Acquiror/Paying Agent.

4. Inquiries. All questions regarding appropriate procedures for surrendering shares of Stock should be directed to Paying Agent at the mailing address or telephone number set forth on the front page.

5. Additional Copies. Additional copies of this Letter of Transmittal may be obtained from Paying Agent at the mailing address set forth on the front page.

6. Internal Revenue Service Forms. Under U.S. federal income tax law, each United States holder surrendering shares of Stock for Payment is required to provide Acquiror with a correct Taxpayer Identification Number on Substitute Form W-9, and to indicate whether the holder is subject to backup withholding. Additionally, each non-United States holder is required to provide Acquiror properly executed Internal Revenue Service Form W-8BEN or other applicable Form W-8. Please see “IMPORTANT TAX INFORMATION” above.

7. Miscellaneous. Any and all Letters of Transmittal or facsimiles (including any other required documents) not in proper form are subject to rejection.

GUIDELINES FOR REQUEST FOR TAXPAYER IDENTIFICATION

NUMBER ON SUBSTITUTE FORM W-9

General Instructions. All section references are to the Internal Revenue Code unless otherwise stated.

U.S. person. Use Form W-9 only if you are a U.S. person (including a resident alien), to provide your correct TIN to the person requesting it (the requester) and to:

1. Certify that the TIN you are giving is correct (or you are waiting for a number to be issued),

2. Certify that you are not subject to backup withholding, or

3. Claim exemption from backup withholding if you are a U.S. exempt payee.

For federal tax purposes you are considered a U.S. person if you are:

1. An individual who is a citizen or resident of the Xxxxxx Xxxxxx,

0. A partnership, corporation, company, or association created or organized in the United States or under the laws of the United States, or

3. Any estate (other than a foreign estate) or domestic trust. See Regulations sections 301.7701-6(a) and 7(a) for additional information.

Partners and partnerships must consult their own tax advisors regarding the application of these rules to them.

Foreign person. If you are a foreign person, do not use Substitute Form W-9. Instead, use the appropriate Form W-8 (see Publication 515, Withholding of Tax on Nonresident Aliens and Foreign Entities).

Nonresident alien who becomes a resident alien. Generally, only a nonresident alien individual may use the terms of a tax treaty to reduce or eliminate U.S. tax on certain types of income. However, most tax treaties contain a provision known as a “saving clause.” Exceptions specified in the saving clause may permit an exemption from tax to continue for certain types of income even after the recipient has otherwise become a U.S. resident alien for tax purposes. If you are a U.S. resident alien who is relying on an exception contained in the saving clause of a tax treaty to claim an exemption from U.S. tax on certain types of income, you must attach a statement to Substitute Form W-9 that specifies the following five items:

1. The treaty country. Generally, this must be the same treaty under which you claimed exemption from tax as a nonresident alien.

2. The treaty article addressing the income.

3. The article number (or location) in the tax treaty that contains the saving clause and its exceptions.

4. The type and amount of income that qualifies for the exemption from tax.

5. Sufficient facts to justify the exemption from tax under the terms of the treaty article.

- 1 -

Example. Article 20 of the U.S.-China income tax treaty allows an exemption from tax for scholarship income received by a Chinese student temporarily present in the United States. Under U.S. law, this student will become a resident alien for tax purposes if his or her stay in the United States exceeds 5 calendar years. However, paragraph 2 of the first Protocol to the U.S.-China treaty (dated April 30, 1984) allows the provisions of Article 20 to continue to apply even after the Chinese student becomes a resident alien of the United States. A Chinese student who qualifies for this exception (under paragraph 2 of the first protocol) and is relying on this exception to claim an exemption from tax on his or her scholarship or fellowship income would attach to Substitute Form W-9 a statement that includes the information described above to support that exemption.

If you are a nonresident alien or a foreign entity not subject to backup withholding, give the requester the appropriate completed Form W-8.

What is backup withholding? Persons making certain payments to you must under certain conditions withhold and pay to the IRS 28% of such payments. This is called “backup withholding.” Payments that may be subject to backup withholding include interest, dividends, broker and barter exchange transactions, rents, royalties, nonemployee pay, and certain payments from fishing boat operators. Real estate transactions are not subject to backup withholding.

You will not be subject to backup withholding on payments you receive if you give the requester your correct TIN, make the proper certifications, and report all your taxable interest and dividends on your tax return.

Payments you receive will be subject to backup withholding if:

1. You do not furnish your TIN to the requester, or

2. You do not certify your TIN when required (see the Part II instructions below for details), or

3. The IRS tells the requester that you furnished an incorrect TIN, or

4. The IRS tells you that you are subject to backup withholding because you did not report all your interest and dividends on your tax return (for reportable interest and dividends only), or

5. You do not certify to the requester that you are not subject to backup withholding under 4 above (for reportable interest and dividend accounts opened after 1983 only). Certain payees and payments are exempt from backup withholding. See the instructions below and the separate Instructions for the Requester of Form W-9.

Updating Your Information

You must provide updated information to any person to whom you claimed to be an exempt payee if you are no longer an exempt payee and anticipate receiving reportable payments in the future from this person. For example, you may need to provide updated information if you are a C corporation that elects to be an S corporation, or if you no longer are tax exempt. In addition, you must furnish a new Form W-9 if the name or TIN changes for the account, for example, if the grantor of a grantor trust dies.

- 2 -

Penalties

Failure to furnish TIN. If you fail to furnish your correct TIN to a requester, you are subject to a penalty of $50 for each such failure unless your failure is due to reasonable cause and not to willful neglect.

Civil penalty for false information with respect to withholding. If you make a false statement with no reasonable basis that results in no backup withholding, you are subject to a $500 penalty.

Criminal penalty for falsifying information. Willfully falsifying certifications or affirmations may subject you to criminal penalties including fines and/or imprisonment.

Misuse of TINs. If the requester discloses or uses TINs in violation of federal law, the requester may be subject to civil and criminal penalties.

Specific Instructions

Name

If you are an individual, you must generally enter the name shown on your income tax return. However, if you have changed your last name, for instance, due to marriage without informing the Social Security Administration of the name change, enter your first name, the last name shown on your social security card, and your new last name. If the account is in joint names, list first, and then circle, the name of the person or entity whose number you entered in Part I of the form.

Sole proprietor. Enter your individual name as shown on your income tax return on the “Name” line. You may enter your business, trade, or “doing business as (DBA)” name on the “Business name” line.

Disregarded entity. If the person identified on the “Name” line is an LLC, check the “Limited liability company” box only and enter the appropriate code for the tax classification in the space provided. If you are an LLC that is treated as a partnership for federal tax purposes, enter “P” for partnership. If you are an LLC that has filed a Form 8832 or a Form 2553 to be taxed as a corporation, enter “C” for C corporation or “S” for S corporation. If you are an LLC that is disregarded as an entity separate from its owner under Regulation section 301.7701-3 (except for employment and excise tax), do not check the LLC box unless the owner of the LLC (required to be identified on the “Name” line) is another LLC that is not disregarded for federal tax purposes. If the LLC is disregarded as an entity separate from its owner, enter the appropriate tax classification of the owner identified on the “Name” line.

Note. Check the appropriate box for the federal tax classification of the person whose name is entered on the “Name” line (Individual/sole proprietor, Partnership, C Corporation, S Corporation, Trust/estate).

Other entities. Enter your business name as shown on required Federal tax documents on the “Name” line. This name should match the name shown on the charter or other legal document creating the entity. You may enter any business, trade, or DBA name on the “Business name” line.

Generally, individuals (including sole proprietors) are not exempt from backup withholding. Corporations are exempt from backup withholding for certain payments, such as interest and dividends.

Note: If you are exempt from backup withholding, you should still complete this form to avoid possible erroneous backup withholding.

The chart below shows types of payments that may be exempt from backup withholding. The chart applies to the exempt recipients listed above, 1 through 15.

IF the payment is for . . .		THEN the payment is exempt for . . .
Interest and dividend payments		All exempt recipients except for 9
Broker transactions		Exempt recipients 1 through 5 and 7 through 13. Also, C corporations.
Barter exchange transactions and patronage dividends		Exempt recipients 1 through 5
Payments over $600 required to be reported and direct sales over $5,000 (1)		Generally, exempt recipients 1 through 7 (2)

(1) See Form 1099-MISC, Miscellaneous Income, and its instructions.

(2) However, the following payments made to a corporation (including gross proceeds paid to an attorney under section 6045(f), even if the attorney is a corporation) and reportable on Form 1099-MISC are not exempt from backup withholding: medical and health care payments, attorneys’ fees; and payments for services paid by a Federal executive agency.

Part I. Taxpayer Identification Number (TIN)

Enter your TIN in the appropriate box. If you are a resident alien and you do not have and are not eligible to get an SSN, your TIN is your IRS individual taxpayer identification number (ITIN). Enter it in the social security number box. If you do not have an ITIN, see How to get a TIN below.

If you are a sole proprietor and you have an EIN, you may enter either your SSN or EIN. However, the IRS prefers that you use your SSN.

If you are a single-owner LLC that is disregarded as an entity separate from its owner, enter your SSN (or EIN, if the owner has one). If the LLC is a corporation, partnership, etc., enter the entity’s EIN.

Note. See the chart below for further clarification of name and TIN combinations.

How to get a TIN. If you do not have a TIN, apply for one immediately. To apply for an SSN, get Form SS-5, Application for a Social Security Card, from your local Social Security Administration office or get this form online at xxx.xxxxxxxxxxxxxx.xxx/xxxxxx/xx-0.xxx. You may also get this form by calling 0-000-000-0000. Use Form W-7, Application for IRS Individual Taxpayer Identification Number, to apply for an ITIN, or Form SS-4, Application for Employer Identification Number, to apply for an EIN. You can apply for an EIN online by accessing the IRS website at xxx.xxx.xxx/xxxxxxxxxx/ and clicking on Employer Identification Numbers (EIN) under Starting a Business. You can get Forms W-7 and SS-4 from the IRS by visiting xxx.xxx.xxx or by calling 0-000-XXX-XXXX (0-000-000-0000). If you are asked to complete Substitute Form W-9 but do not

- 5 -

have a TIN, fill out the box entitled “CERTIFICATE OF AWAITING TAXPAYER IDENTIFICATION NUMBER.” For interest and dividend payments, and certain payments made with respect to readily tradable instruments, generally you will have 60 days to get a TIN and give it to the requester before you are subject to backup withholding on payments. The 60-day rule does not apply to other types of payments. You will be subject to backup withholding on all such payments until you provide your TIN to the requester.

Note. Entering “Applied For” means that you have already applied for a TIN or that you intend to apply for one soon.

Caution: A disregarded domestic entity that has a foreign owner must use the appropriate Form W-8.

Part II. Certification

To establish to the withholding agent that you are a U.S. person, or resident alien, sign Substitute Form W-9.

For a joint account, only the person whose TIN is shown in Part I should sign (when required). Exempt recipients, see Exempt From Backup Withholding above.

Signature requirements. Complete the certification as indicated in 1 through 4 below.

1. Interest, dividend, broker, and barter exchange accounts opened after 1983 and broker accounts considered inactive during 1983. You must sign the certification or backup withholding will apply. If you are subject to backup withholding and you are merely providing your correct TIN to the requester, you must cross out item 2 in the certification before signing the form.

2. Real estate transactions. You must sign the certification. You may cross out item 2 of the certification.

3. Other payments. You must give your correct TIN, but you do not have to sign the certification unless you have been notified that you have previously given an incorrect TIN. “Other payments” include payments made in the course of the requester’s trade or business for rents, royalties, goods (other than bills for merchandise), medical and health care services (including payments to corporations), payments to a nonemployee for services, payments to certain fishing boat crew members and fishermen, and gross proceeds paid to attorneys (including payments to corporations).

4. Mortgage interest paid by you, acquisition or abandonment of secured property, cancellation of debt, qualified tuition program payments (under section 529), XXX, Xxxxxxxxx ESA, Xxxxxx MSA or HSA contributions or distributions, and pension distributions. You must give your correct TIN, but you do not have to sign the certification.
