RECITALS

WHEREAS, the Board of Directors of Parent has approved, and deems it advisable and in the best interests of its stockholders to consummate, the merger (the “Merger”) of Merger Sub with and into the Company, upon the terms and subject to the conditions set forth herein; and

WHEREAS, the Board of Directors of the Company (the “Company Board”), having carefully considered the long-term prospects and interests of the Company and its stockholders and determined that the Merger is advisable and that it is in the best interest of its stockholders to consummate the transactions contemplated hereby, has approved the transactions contemplated hereby and has resolved to recommend to its stockholders the adoption of this Agreement, the Merger and the other transactions contemplated hereby, upon the terms and subject to the conditions set forth herein; and

WHEREAS, an irrevocable action by written consent of Company Stockholders sufficient to adopt this Agreement and the Merger and to consummate the transactions contemplated hereby in accordance with the provisions of the Delaware General Corporation Law (“Delaware Law”) is being delivered to Parent immediately following the execution of this Agreement; and

WHEREAS, the Boards of Directors of each of Parent, Merger Sub and the Company, and the sole stockholder of Merger Sub have approved this Agreement, the Merger and the other transactions contemplated hereby in accordance with the provisions of Delaware Law; and

NOW, THEREFORE, in consideration of the foregoing and the respective covenants, agreements, representations and warranties set forth herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

ARTICLE I

THE MERGER

Section 1.1 The Merger. At the Effective Time and subject to and upon the terms and conditions of this Agreement and the applicable provisions of Delaware Law, Merger Sub shall be merged with and into the Company, the separate corporate existence of Merger Sub shall cease and the Company shall continue as the Surviving Corporation and a wholly owned subsidiary of Parent. The Company, as the Surviving Corporation after the Merger, is hereinafter sometimes referred to as the “Surviving Corporation.”

Section 1.2 Closing. The closing of the Merger (the “Closing”) shall take place at 10:00 a.m., California time, on a date (the “Closing Date”), to be specified by the parties, which shall be no later than the third Business Day after satisfaction or waiver of all of the conditions set forth in ARTICLE VI of this Agreement (other than the conditions which can be satisfied only on the Closing Date) at the offices of Skadden, Arps, Slate, Meagher & Flom LLP, Four Embarcadero Center, Suite 3800, San Francisco, California 94111, or such other time, date or place as agreed to in writing by the parties hereto; provided, however, that if the third Business Day after satisfaction or waiver of all such conditions shall be less than five (5) Business Days before December 31, 2010, the parties agree that the Closing Date shall be December 31, 2010. All deliveries to be made or other actions to be taken at the Closing shall be deemed to occur simultaneously, and no such delivery or action shall be deemed complete until all such deliveries and actions have been completed or the relevant parties have agreed to waive such delivery or action. If the Closing does not occur, any delivery made or other action taken at the Closing shall be deemed not to have occurred and be without force or effect.

Section 1.3 Effective Time. Upon the terms and subject to the conditions set forth in ARTICLE VI of this Agreement the parties hereto shall cause the Merger to be consummated by filing a certificate of merger with the Secretary of State of the State of Delaware (the “Certificate of Merger”). The parties hereto shall make all other filings, recordings or publications required by all applicable Legal Requirements in connection with the Merger. The Merger shall become effective upon the filing of the Certificate of Merger with the Secretary of State of the State of Delaware pursuant to Delaware Law or at such later time as shall be agreed upon in writing by the parties and specified in the Certificate of Merger (the “Effective Time”), which specified time shall be a time on the Closing Date.

Section 1.4 Effect of the Merger. At the Effective Time, the effect of the Merger shall be as provided in this Agreement, the Certificate of Merger and the applicable provisions of Delaware Law. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time all the property, rights, privileges, powers and franchises of the Company and Merger Sub shall vest in the Surviving Corporation, and all debts, liabilities and duties of the Company and Merger Sub shall become the debts, liabilities and duties of the Surviving Corporation.

Section 1.5 Certificate of Incorporation and Bylaws. At the Effective Time, the Third Amended and Restated Certificate of Incorporation of the Company (the “Company Certificate of Incorporation”) shall be amended and restated in its entirety to be identical to the certificate of incorporation of Merger Sub, as in effect immediately prior to the Effective Time, until thereafter amended in accordance with Delaware Law and as provided in such Company Certificate of Incorporation; provided, however, that at the Effective Time, ARTICLE I of the certificate of incorporation of the Surviving Corporation shall be amended and restated in its entirety to read as follows: “The name of the corporation is US Oncology Holdings, Inc.” At the Effective Time, the bylaws of the Company (the “Company Bylaws”) shall be amended and restated in their entirety to be identical to the bylaws of Merger Sub, as in effect immediately prior to the Effective Time, until thereafter amended in accordance with Delaware Law and as provided in such Company Bylaws.

Section 1.6 Directors and Officers. Unless otherwise determined by Parent prior to the Effective Time, the initial directors of the Surviving Corporation shall be the directors of Merger Sub immediately prior to the Effective Time, until their respective successors are duly elected or appointed and qualified. Unless otherwise determined by Parent prior to the Effective Time, the initial officers of the Surviving Corporation shall be the officers of Merger Sub immediately prior to the Effective Time, until their respective successors are duly appointed.

Section 1.7 Consideration for the Merger.

(a) Notwithstanding any other provision of this Agreement, the aggregate amount (including any amounts withheld pursuant to Section 1.14) Parent shall pay or cause to be paid to the holders of shares of Company Common Stock that are not subject to restriction or a right of repurchase by the Company (the “Company Stockholders”) and holders of Company Options, Company Restricted Stock and all other equity interests of the Company (collectively, together with the Company Stockholders, the “Company Holders”) in exchange for the acquisition by Parent of all shares of Company Common Stock and the cancellation or termination, as applicable, of Company Options and Company Restricted Stock and other similar rights to acquire Company Common Stock or other equity securities of the Company (whether vested, unvested, earned, unearned or contingent) (the “Purchase Price”) shall be an amount in cash equal to:

(i) Two Billion One Hundred Sixty Million Dollars ($2,160,000,000) (the “Base Consideration”);

(ii) minus the Indebtedness Adjustment;

(iii) plus the Cash Credit Amount;

(iv) minus the aggregate amount of the Change of Control and Severance Payments; and

(v) minus the aggregate amount of Company Transaction Expenses unpaid as of the close of business on the day immediately prior to the Closing Date;

(vi) minus the amount, if any, by which (A) Seventy Five Million Dollars ($75,000,000) exceeds (B) thirty-seven and a half percent (37.5%) of the aggregate amount of all prepayment premiums, penalties, breakage costs or similar obligations payable in connection with (x) the redemption of the Redeemed Notes pursuant to Section 5.11(b) and (y) the payment of any Indebtedness incurred to prepay, redeem, repurchase or otherwise retire or extinguish such Redeemed Notes (unless, in case of such Indebtedness, Parent reasonably determines that it will not be entitled to deduct the full amount of such prepayment premiums, penalties, breakage costs or similar obligations in the tax year in which such payment is made) (the “Tax Benefit Adjustment”); provided that if any Redeemed Notes are prepaid, redeemed, repurchased or otherwise retired or extinguished prior to the Effective Time, whether as permitted pursuant to Section 4.2 or otherwise, then the amount to be used in clause (B)(x) of the calculation of the Tax Benefit Adjustment with respect to such Redeemed Notes shall be zero ($0);

(vii) minus, the aggregate amount of Indebtedness repaid by the Company on or after the date hereof, excluding any Indebtedness that is concurrently replaced by Indebtedness of an equal or greater amount; and

(viii) minus an amount equal to forty percent (40%) of the aggregate amount of any payments or benefits paid or that may become payable in connection with this Agreement, the Merger, the transactions contemplated hereby or any Company Employee Plan (directly or indirectly, including payments or benefits contingent upon the occurrence of another event) that would not be deductible by reason of Section 280G of the Code.

(b) The Purchase Price shall be comprised of:

(i) an amount equal to Twenty Five Million Dollars ($25,000,000) in cash (the “Escrow Amount”), which shall be deposited with the Escrow Agent pursuant to Section 8.1;

(ii) an amount equal to One Million Dollars ($1,000,000) in cash (the “Stockholders’ Agent Reimbursement Escrow Amount”), which shall be deposited with the Escrow Agent to be used by the Stockholders’ Agent with respect to Agent Expenses; and

(iii) an amount equal to the Purchase Price minus (x) the Escrow Amount and (y) the Stockholders’ Agent Reimbursement Escrow Amount, which shall be payable in cash to the Company Holders in accordance with Sections 1.8, 1.9 and 1.10

and shall be subject to adjustment pursuant to ARTICLE VIII.

(c) Prior to the Closing, in addition to such other actions as may be provided for herein the Company shall deliver to Parent, at least five (5) Business Days prior to the Closing, a closing statement (the “Closing Statement”) setting forth the Company’s calculation of the Purchase Price, which shall be determined in accordance with Section 1.7(a) and shall set forth, as of the anticipated Closing Date (i) the Indebtedness Adjustment, (ii) the aggregate amount of the Change of Control and Severance Payments, (iii) the Company Transaction Expenses, the Persons owed such amounts and, to the extent available to the Company, the bank account and wire transfer information for such Person and (iv) the Tax Benefit Adjustment, each as a separate line item.

(d) At the Closing, in addition to such other actions as may be provided for herein:

(i) The Company shall deliver a certification by an officer of the Company that the Closing Statement correctly reflects the calculations contained therein as required to be made pursuant to this Agreement;

Section 1.8 Effect on Capital Stock.

(a) Conversion of Company Common Stock. Except as provided in Sections 1.8(c) and 1.8(d), each share, par value $0.001 per share, of common stock of the Company (“Company Common Stock”) issued and outstanding immediately prior to the Effective Time (other than shares of Company Restricted Stock) shall, by virtue of the Merger and without any action on the part of the holder thereof, be cancelled and shall automatically be converted into the right to receive (i) the Per Share Initial Merger Consideration and (ii) any amounts required to be paid with respect to such share to the former holder thereof in accordance with the terms of Section 8.3 and the Escrow Agreement, if, as and when such payments are required to be made. The amount of cash each Company Stockholder is entitled to receive for the shares of Company Common Stock held by such Company Stockholder as of immediately before the Effective Time shall be rounded to the nearest cent and computed after aggregating cash amounts for all shares of Company Common Stock held by such Company Stockholder immediately prior to the Effective Time.

(b) Capital Stock of Merger Sub. As of the Effective Time, by virtue of the Merger and without any action on the part of any of the parties hereto or any holder thereof, each share of common stock of Merger Sub issued and outstanding immediately prior to the Effective Time shall be cancelled and shall automatically be converted into one validly issued, fully paid and nonassessable share of common stock of the Surviving Corporation. Each stock certificate of Merger Sub evidencing ownership of any such shares of common stock shall evidence ownership of such shares of capital stock of the Surviving Corporation.

(c) Dissenters’ Rights. “Dissenting Shares” means any shares of Company Common Stock issued and outstanding immediately prior to the Effective Time and held by a holder who has not voted in favor of the Merger or consented thereto in writing and who has demanded properly in writing appraisal for such shares of Company Common Stock in accordance with Section 262 of Delaware Law.

(i) Subject to clause (ii) of this Section 1.8(c), notwithstanding any provision of this Agreement to the contrary, Dissenting Shares shall not be converted as provided in Section 1.8(a), but the holder thereof shall be entitled only to such rights as are granted by Delaware Law.

(ii) Notwithstanding the provisions of clause (i) of this Section 1.8(c), if any holder of shares of Company Common Stock who demands appraisal of such holder’s shares of Company Common Stock under Delaware Law effectively withdraws or loses (through failure to perfect or otherwise) such holder’s right to appraisal, then as of the Effective Time or the occurrence of such event, whichever later occurs, such holder’s shares of Company Common Stock shall automatically be converted into the right to receive the consideration set forth in Section 1.8(a) upon surrender of the Company Certificates representing such Company Common Stock pursuant to Section 1.10.

(iii) The Company shall give Parent (x) prompt notice of any written demands for appraisal or payment of the fair value of any shares of Company Common Stock, withdrawals of such demands, and any other instruments served on the Company pursuant to Delaware Law or the Legal Requirements of any other applicable jurisdiction, and (y) the opportunity to direct all negotiations and

proceedings with respect to demands for appraisal under Delaware Law or the Legal Requirements of any other applicable jurisdiction. Except with the prior written consent of Parent, the Company shall not voluntarily make any payment with respect to any demands for appraisal or settle, or offer to settle, any such demands.

(d) Cancellation of Certain Company Common Stock. Notwithstanding anything herein to the contrary, at the Effective Time, all shares of Company Common Stock that are owned by the Company as treasury stock, and all shares of Company Common Stock owned by Parent or any direct or indirect wholly owned Subsidiary of Parent or of the Company immediately prior to the Effective Time shall be cancelled and extinguished without any conversion thereof and shall not be taken into account for purposes of any amounts payable to the Company Holders hereunder.

Section 1.9 Company Options and Company Restricted Stock.

(a) Company Options. Subject to consummation of the Merger, immediately prior to the Effective Time, each outstanding Company Option that is unexpired and unexercised, whether or not vested or exercisable prior to or as a result of the consummation of the Merger, shall be accelerated in full so that each such Company Option becomes fully vested and exercisable. Subject to consummation of the Merger, at the Effective Time, each Company Option outstanding shall be cancelled and each such Company Stock Option that has a per share exercise price lower than the Per Share Merger Consideration shall automatically be converted into the right to receive (i) an amount in cash equal to the product of (A) the number of shares of Company Common Stock that would have been issuable upon exercise of such Company Stock Option immediately before the Effective Time multiplied by (B) the excess of the Per Share Merger Consideration over the per share exercise price for such Company Stock Option, subject to any setoff, deduction or withholding contemplated in this Agreement and (ii) any amounts required to be paid with respect to such share to the former holder thereof in accordance with the terms of Section 8.3 and the Escrow Agreement, if, as and when such payments are required to be made. As of the Effective Time, the Company Options shall terminate and cease to be outstanding.

(b) Company Restricted Stock. Subject to consummation of the Merger, at the Effective Time, each Company Restricted Stock award that is unvested and outstanding immediately before the Effective Time shall be cancelled and automatically converted into the right to receive (i) an amount in cash equal to the product of (A) the number of shares of Company Common Stock subject to such Company Restricted Stock award immediately prior to the Effective Time, multiplied by (B) the Per Share Merger Consideration, subject to any setoff, deduction or withholding contemplated in this Agreement and (ii) any amounts required to be paid with respect to such share to the former holder thereof in accordance with the terms of Section 8.3 and the Escrow Agreement, if, as and when such payments are required to be made. As of the Effective Time, the Company Restricted Stock awards shall terminate and cease to be outstanding.

(c) The Company shall take all steps necessary prior to the Effective Time to cause the Company Options and Company Restricted Stock to be treated as set forth in this Section 1.9, including providing any necessary notices and obtaining any necessary consents or waivers. Copies of the relevant agreements governing all Company Options and Company Restricted Stock have been made available to Parent.

Section 1.10 Surrender of Certificates and Payment.

(a) Paying Agent. Bank of New York (or its successor in interest or other institution selected by Parent with the reasonable consent of the Company) shall act as paying agent (the “Paying Agent”) in the Merger.

(b) Parent to Provide Cash. Contemporaneously with the filing of the Certificate of Merger pursuant to Section 1.3, Parent shall deliver to the Paying Agent for exchange and payment in accordance with this ARTICLE I, through such reasonable procedures as Parent may adopt, an aggregate amount of cash sufficient to make the payments required by Section 1.8(a); provided, that in the case of payments to employees or former employees of the Company for which Tax withholding is required, Parent may elect to make such payments on the first reasonably practicable payroll date after the Closing through the Company’s or Parent’s payroll processing service or system in lieu of making such payments through the Paying Agent.

(c) Exchange Procedures. At least fifteen (15) days prior to the Closing, Parent shall cause to be mailed to each holder of record of a certificate or certificates representing Company Common Stock (each such certificate, a “Company Certificate”) a letter of transmittal in the form attached hereto as Exhibit A and instructions to the letter of transmittal for use in effecting the surrender of the Company Certificates in exchange for the merger consideration. After the Effective Time and upon surrender of all Company Certificates held by a Company Holder for cancellation to the Paying Agent or to such other agent or agents as may be appointed by Parent, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, the Company Certificates so surrendered shall forthwith be cancelled and, subject to Section 1.14, the holder of such Company Certificates shall be entitled to receive in exchange therefor the applicable payments pursuant to Section 1.8(a); provided that in the event a Company Holder delivers Company Certificates held by such Company Holder for cancellation to the Paying Agent or to such other agent or agents as may be appointed by Parent, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, by the Closing, Parent shall use its commercial reasonable efforts to cause the Paying Agent to make payment by wire transfer to such Company Holder on the Closing Date or on the next succeeding Business Day of the applicable amounts pursuant to Section 1.8(a). Until so surrendered, each outstanding Company Certificate that, prior to the Effective Time, represented Company Common Stock will be deemed from and after the Effective Time, for all purposes, to evidence solely the right to receive the applicable payments pursuant to Section 1.8(a).

(d) Conversion Schedule.

(e) Transfers of Ownership. If any merger consideration is to be distributed to a name other than that in which the Company Certificate surrendered in exchange therefor is registered, it will be a condition of the issuance thereof that the Company Certificate so surrendered will be properly endorsed and otherwise in proper form for transfer and that the Person requesting such exchange will have paid to Parent or any agent designated by it any transfer or other Taxes required by reason of payment in cash to any name other than that of the registered holder of the Company Certificate surrendered, or established to the satisfaction of Parent or any agent designated by it that such Tax has been paid or is not payable.

(f) No Liability. Notwithstanding anything to the contrary in this Section 1.10, none of the Paying Agent, the Surviving Corporation or any party hereto shall be liable to any Person for any amount properly paid to a public official pursuant to any applicable abandoned property, escheat or similar Legal Requirements.

(g) Return of Merger Consideration. Any merger consideration made available to the Paying Agent and not exchanged for Company Certificates in accordance with this Section 1.10 within six (6) months after the Effective Time shall be redelivered or repaid by the Paying Agent to Parent, after which time any holder of Company Certificates who has not theretofore delivered or surrendered such Company Certificates to the Paying Agent, subject to applicable Legal Requirements, shall look as a general creditor only to Parent for payment of the merger consideration. If any Company Certificates are not surrendered prior to the earlier of the second anniversary of the Effective Time and such time as the unclaimed merger consideration payable in exchange therefor would otherwise escheat to or become property of any Governmental Authority, such unclaimed merger consideration shall, to the extent permitted by applicable Legal Requirements, become the property of the Surviving Corporation, free and clear of all claims or interest of any Person previously entitled thereto.

If, after the Effective Time, Company Certificates are presented to Parent or the Surviving Corporation for any reason, they shall be cancelled and exchanged as provided in this ARTICLE I. Payments due under this ARTICLE I shall be made without interest.

Section 1.12 Lost, Stolen or Destroyed Certificates. In the event that any Company Certificates shall have been lost, stolen or destroyed, Parent shall cause to be paid in exchange for such lost, stolen or destroyed Company Certificates, upon the making of an affidavit of that fact by the holder thereof in a form reasonably satisfactory to Parent, such payment of the merger consideration as may be required pursuant to this ARTICLE I; provided, however, that Parent may, in its discretion and as a condition precedent to the issuance thereof, require the owner of such lost, stolen or destroyed Company Certificates to deliver a bond in such sum as it may reasonably direct as indemnity against any claim that may be made against Parent or the Surviving Corporation with respect to the Company Certificates alleged to have been lost, stolen or destroyed.

Section 1.13 Taking of Necessary Action; Further Action. If, at any time after the Effective Time, any further action is necessary or desirable to carry out the purposes of this Agreement and to vest the Surviving Corporation with full right, title and possession to all assets, property, rights, privileges, powers and franchises of the Company, the officers and directors of Parent, the Company and the Surviving Corporation are fully authorized in the name of their respective entities or otherwise to take, and will take, all such lawful and necessary action, so long as such action is not inconsistent with this Agreement.

Section 1.14 Tax Withholding. Each of Parent, Merger Sub, the Surviving Corporation, the Escrow Agent and the Paying Agent, as the case may be, shall be entitled to deduct and withhold from the Purchase Price payable hereunder, or other payment otherwise payable pursuant to this Agreement or the Escrow Agreement, the amounts required to be deducted and withheld under the Code, or any provision of any U.S. federal, state or local or any non-U.S. Tax law. Any amounts so withheld shall be paid over to the appropriate Governmental Authority. To the extent that amounts are so deducted and withheld, such deducted and withheld amounts shall be treated for all purposes of this Agreement as having been paid to such holder in respect of whom such deduction and withholding was made.

Section 1.15 Transfer Taxes. All transfer, documentary, sales, use, stamp, registration and such other Taxes and fees (including any penalties and interest) imposed on any Company Holder or other Person entitled to receive merger consideration pursuant to the terms of this Agreement shall be borne and paid by such Company Holder or Person.

Section 2.3 Authority; No Conflict.

(a) The Company has the requisite corporate power and authority to execute and deliver this Agreement and the other agreements set forth in the exhibits hereto (collectively, the “Ancillary Agreements ”) to which the Company is a party and to consummate the transactions contemplated hereby and thereby. The execution, delivery and performance of this Agreement and the Ancillary Agreements to which the Company is a party and the consummation of the transactions contemplated hereby and thereby have been duly authorized by all necessary corporate action on the part of the Company (other than the adoption of this Agreement and the Merger by the requisite Company Stockholders which adoption will occur immediately following the execution of this Agreement by the Company) and no other corporate action on the part of the Company is necessary to authorize the execution and delivery by the Company of this Agreement and the Ancillary Agreements to which it is a party and the consummation of the transactions contemplated hereby and thereby. This Agreement and each Ancillary Agreement to which the Company is a party have been duly executed and delivered by the Company and constitute the valid and binding obligations of the Company enforceable against the Company in accordance with their terms, except to the extent that enforceability may be limited by the effect, if any, of (i) any applicable bankruptcy, reorganization, insolvency, moratorium or other Legal Requirements affecting the enforcement of creditors’ rights generally, and (ii) general principles of equity, regardless of whether such enforceability is considered in a proceeding at law or in equity.

(b) Neither the execution and delivery by the Company of this Agreement or any Ancillary Agreement, nor the consummation of the transactions contemplated hereby and thereby will conflict with, or result in any breach or violation of, default under (with or without notice or lapse of time, or both), or give rise to any right of termination, cancellation, modification or acceleration, or any obligation or loss of any benefit under (i) any provision of the Company Certificate of Incorporation or the Company Bylaws, or the governing documents of any Subsidiary of the Company, (ii) assuming that all consents, waivers and approvals set forth in Section 2.20 of the Company Disclosure Schedule are duly obtained, any Contract to which the Company or any of its Subsidiaries is a party or to which any of their respective properties or assets are bound (other than rights of termination or cancellation under any such Contract that may be canceled without cause by the other party thereto without penalty to such party upon notice of 90 days or less) or (iii) subject to the exceptions set forth in the sentence that immediately follows, any Legal Requirement applicable to the Company, any of its Subsidiaries, any of the Hospital Joint Ventures, any of the Managed Practices, or any of their respective properties or assets; except in the case of clauses (ii) and (iii), for such breaches, violations, defaults, obligations or losses, which, individually or in the aggregate, would not reasonably be expected to be material to the Company or any of its Subsidiaries or to prevent or materially alter or delay the Company’s ability to consummate the Merger. Except for (i) the filing and recordation of the Certificate of Merger and the related certificate of incorporation of the Surviving Corporation in accordance with the requirements of Delaware Law and (ii) such filings as may be required under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”) and any applicable foreign antitrust law, no notice to, filing with, and no Permit, authorization, consent or approval of, any Governmental Authority (“Governmental Authorization”) is necessary for the consummation by the Company of the transactions contemplated by this Agreement.

Section 2.4 Company Reports; Financial Statements.

(a) The Company and its Subsidiaries have filed or furnished, as applicable, on a timely basis, all forms, statements, certifications, reports and documents required to be filed or furnished by it with the Securities and Exchange Commission (the “SEC”) pursuant to the Exchange Act or the Securities Act since January 1, 2008 (the forms, statements, certifications, reports and documents filed or furnished since January 1, 2008 and those filed or furnished subsequent to the date hereof, including any amendments thereto, the “Company Reports”). Each of the Company Reports, at the time of its filing or being furnished complied or, if not yet filed or furnished, will comply in all material respects with the applicable requirements of the Securities Act of 1933 (the “Securities Act”) and the Securities Exchange Act of 1934 (the “Exchange Act”) and any rules and regulations promulgated thereunder applicable to the Company Reports. As of their respective dates (or, if amended prior to the date hereof, as of the date of such amendment), the Company Reports did not, and any Company Reports filed with or furnished to the SEC subsequent to the date hereof will not, contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements made therein, in light of the circumstances in which they were made, not misleading. The Company has made available to Parent copies of all material correspondence between the SEC and the Company since January 1, 2008. As of the date of this Agreement, there are no material outstanding or unresolved comments received from the SEC staff with respect to the Company Reports. Except for US Oncology, Inc., none of the Company’s Subsidiaries is or has been required to file any form, report or other document with the SEC or any securities exchange or quotation service.

Since January 1, 2010, there has been no change in any accounting policies, principles, methods or practices, including any change with respect to reserves (whether for bad debts, contingent liabilities or otherwise), of the Company. Since January 1, 2005, no audit firm has ever declined or indicated its inability to issue an opinion with respect to any financial statements of the Company.

(c) Since January 1, 2008, the Company and each of its Subsidiaries has had in place “disclosure controls and procedures” (as defined in Rules 13a-15(e) and 15d-15(e) promulgated under the Exchange Act) reasonably designed and maintained to ensure that all information (both financial and non-financial) required to be disclosed by the Company or any of its Subsidiaries in the reports that it files or submits to the SEC under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC and that such information is accumulated and communicated to the Company’s or such Subsidiary’s management as appropriate to allow timely decisions regarding required disclosure and to make the certifications of the chief executive officer and chief financial officer of the Company or such Subsidiary required under the Exchange Act with respect to such reports. The Company and each of its Subsidiaries (i) make and keep accurate books and records that fairly reflect the transactions and dispositions of assets of the Company or such Subsidiary, as the case may be, and (ii) maintain internal accounting controls which provide reasonable assurance that (a) transactions are recorded as necessary to permit preparation of their respective financial statements in conformity with GAAP, (b) receipts and expenditures are made only in accordance with general or specific authorizations of management and directors of the Company or such Subsidiary, (c) access to their respective assets is permitted only in accordance with general or specific authorizations of management and directors of the Company or such Subsidiary and (d) the reported accounting for their respective assets and liabilities is compared with existing assets and liabilities at reasonable intervals.

(d) The items marked with an asterisk on Section 2.4(d) of the Company Disclosure Schedule are true and correct.

Section 2.5 Absence of Certain Changes. Since the Interim Balance Sheet Date, the Company and each of its Subsidiaries has (i) conducted its business in the ordinary course consistent with past practice, (ii) has not suffered any Company Material Adverse Effect and no event has occurred that could reasonably be expected to have a Company Material Adverse Effect and (iii) has not taken any action that would be prohibited by Section 4.2 of this Agreement, if taken after the date hereof.

Section 2.6 Absence of Undisclosed Liabilities. Neither the Company nor any of its Subsidiaries has any material liabilities (whether contingent or absolute, direct or indirect, known or unknown to the Company or matured or unmatured or otherwise) of a type required to be reflected or reserved for on a balance sheet prepared in accordance with GAAP other than (i) liabilities and obligations accrued or reserved against in the Interim Balance Sheet, (ii) liabilities and obligations incurred in the ordinary course of business consistent with past practice since the Interim Balance Sheet Date, (iii) performance obligations pursuant to the terms of the Material Contracts and (iv) liabilities and obligations incurred in connection with the transactions contemplated by this Agreement. There are no off balance sheet arrangements (as such term is defined in Item 303(a)(4)(ii) of Regulation S-K of the Securities Act) to which the Company or any of its Subsidiaries is a party or otherwise involving the Company or any of its Subsidiaries.

Except as set forth in Section 2.7(g)(i) of the Company Disclosure Schedule, each of the Company, its Subsidiaries and the Hospital Joint Ventures owns, holds or possesses, and lawfully uses, in the operation of its business all material Permits that are necessary for it to conduct its business as now conducted (each, a “Company Authorization”), including Health Care Company Authorizations. For purposes of this Agreement “Health Care Company Authorizations” shall mean any material Permits from the United States Food and Drug Administration (“FDA”), United States Drug Enforcement Administration (“DEA”), relevant foreign, federal, state and municipal agencies, and any other relevant agencies or Governmental Authorities to purchase, receive, possess, store, transfer, distribute, sell, return, destroy or dispose of any and all products at and from its facilities. All of the Company Authorizations are valid, in full force and effect and sufficient for the services currently provided by the Company, its Subsidiaries and the Hospital Joint Ventures.

Each of Parent and Merger Sub has the corporate power to own its properties and to carry on its business as now being conducted and is duly qualified to do business and, in jurisdictions where such concept is recognized, is in good standing in each jurisdiction in

which the failure to be so qualified and in good standing would have a material adverse effect on the ability of Parent and Merger Sub to consummate the transactions contemplated by this Agreement. Parent and Merger Sub are not in violation of any of the provisions of their respective articles of incorporation, certificate of incorporation or bylaws, except as would not have a material adverse effect on the ability of Parent and Merger Sub to consummate the transactions contemplated by this Agreement.

This Agreement and each Ancillary Agreement to which Parent or Merger Sub is a party have been duly executed and delivered by Parent or Merger Sub, as the case may be, and constitute the valid and binding obligations of Parent or Merger Sub enforceable against Parent or Merger Sub in accordance with their terms, except to the extent that enforceability may be limited by the effect, if any, of (i) any applicable bankruptcy, reorganization, insolvency, moratorium or other Legal Requirements affecting the enforcement of creditors’ rights generally, and (ii) general principles of equity, regardless of whether such enforceability is considered in a proceeding at law or in equity. Neither the execution and delivery by Parent or Merger Sub of this Agreement or any Ancillary Agreement to which it is a party, nor the consummation of the transactions contemplated hereby and thereby will conflict with, or result in any breach or violation of, or default under (with or without notice or lapse of time, or both) or give rise to a right of termination, cancellation or obligation or loss of any benefit under (i) any provision of the articles of incorporation, certificate of incorporation or bylaws of Parent or Merger Sub, or (ii) any Legal Requirement applicable to either Parent or Merger Sub or any of their respective properties or assets, except, in the case of clause (iii) above, any such conflicts, breaches, violations, defaults, rights or losses, which would not, individually or in the aggregate, prevent or materially and adversely delay the consummation by Parent or Merger Sub of the transactions contemplated by this Agreement. Except for (i) the filing and recordation of the Certificate of Merger and the related certificate of incorporation of the Surviving Corporation in accordance with the requirements of Delaware Law and (ii) such filings as may be required under the HSR Act and any applicable foreign antitrust law, no notice to, filing with, and no permit, authorization, consent or approval of, any Governmental Authority, or any private third party is necessary for the consummation by Parent and Merger Sub of the transactions contemplated by this Agreement.

Section 3.3 Interim Operations of Merger Sub. Merger Sub was formed by Parent solely for the purpose of engaging in the transactions contemplated by this Agreement, has engaged in no other business activities and has conducted its operations only as contemplated by this Agreement.

Section 3.4 Litigation. There is no private or governmental action, lawsuit or other legal proceeding pending (or, to the knowledge of Parent, being threatened) against Parent or its Subsidiaries or any of their respective properties or any of their respective officers or directors (in their capacities as such) that would reasonably be expected to prevent or materially and adversely delay the consummation by Parent or Merger Sub of the transactions contemplated by this Agreement.

Section 3.5 Brokers’ and Finders’ Fees. Parent has not incurred, nor will it incur, directly or indirectly, any liability for brokerage or finders’ fees or agents’ commissions or investment bankers’ fees or any similar charges in connection with this Agreement or the transactions contemplated hereby for which the Company or any Company Holder shall have any liability.

Such consents, waivers and approvals under subsection (iii) hereof shall be in a form reasonably acceptable to Parent, and with respect to the consents, waivers and approvals required pursuant to Section 6.3(c), Parent shall have reasonable discretion to determine the form thereof. In the event the Merger does not close for any reason, Parent shall not have any liability to the Company, the Company Holders or any other Person for any costs, claims, liabilities or damages resulting from the Company seeking to obtain such consents, waivers and approvals under subsection (iii) hereof.

(d) Financing Cooperation. In furtherance of the foregoing but without limiting the generality of Section 5.4(c), the Company shall, and shall cause its Subsidiaries and their respective officers, directors, employees and agents to, reasonably cooperate with Parent in connection with obtaining any financing Parent deems necessary to consummate the transactions contemplated hereby (the “Financing”), including by (i) providing direct contact between prospective lenders and the officers and directors of the Company and its Subsidiaries, (ii) providing assistance in preparation of confidential information memoranda, prospectuses and other materials to be used in connection with the Financing, (iii) providing assistance in the preparation for, and participating in, meetings, due diligence sessions, road shows and similar presentations to and with, among others, prospective lenders, investors and rating agencies, (iv) providing any financial information necessary for the satisfaction of the obligations and conditions set forth in any commitment letters or similar agreements and (v) undertaking such other actions, all as Parent may reasonably request in connection with the Financing. Notwithstanding the foregoing, the Company shall have no obligation hereunder to execute any binding commitment or obligation in connection with Parent’s efforts to obtain any financing.

(e) No Divestiture. Notwithstanding anything in this Agreement to the contrary, nothing contained in this Agreement shall be deemed to require Parent or any Subsidiary or affiliate thereof to agree to any Action of Divestiture. The Company shall not, without the prior written consent of Parent, take or agree to take any Action of Divestiture. For purposes of this Agreement, an “Action of Divestiture” means (i) any license, sale or other disposition or holding separate (through establishment of a trust or otherwise) of any shares of capital stock or of any business, assets or properties of Parent, its Subsidiaries or affiliates, or the Company or any of its Subsidiaries, (ii) the imposition of any limitation on the ability of Parent, its Subsidiaries or affiliates, or the Company or any of its Subsidiaries to conduct their respective businesses or own any capital stock or assets or to acquire, hold or exercise full rights of ownership of their respective businesses and, in the case of Parent, the businesses of the Company and each of its Subsidiaries, or (iii) the imposition of any impediment on Parent, its Subsidiaries or affiliates, or the Company or any of its Subsidiaries under any statute, rule, regulation, executive order, decree, order or other legal restraint governing competition, monopolies or restrictive trade practices.

Section 5.5 FIRPTA Certificate. The Company shall, on or prior to the Closing Date, provide Parent with a properly executed Foreign Investment and Real Property Tax Act of 1980 notification letter (the “FIRPTA Certificate”), substantially in the form of Exhibit B attached hereto, which states that shares of capital stock of the Company do not constitute “United States real property interests” under Section 897(c) of the Code, for purposes of satisfying Parent’s obligations under Treasury Regulation Section 1.1445-2(c)(3). In addition, simultaneously with delivery of such FIRPTA Certificate, the Company shall have provided to Parent, as agent for the Company, a form of notice to the IRS in accordance with the requirements of Treasury Regulation Section 1.897-2(h)(2) and in the customary form along with written authorization for Parent to deliver such notice form to the IRS on behalf of the Company upon the Closing of the Merger, all in substantially the form of Exhibit C attached hereto.

(a) From and after the Effective Time, the Surviving Corporation shall: (i) indemnify and hold harmless each individual who served as a director or officer of the Company or any of its Subsidiaries prior to the Effective Time (collectively, the “Indemnified Parties”) to the extent provided for under the terms and conditions of the Company Certificate of Incorporation or the Company Bylaws (each as in effect as of the date hereof), in connection with any Claim (as defined below) and any judgments, damages, losses, claims, liabilities, fines (including excise taxes), penalties and amounts paid in settlement (including all interest, assessments and other charges paid or payable in connection with or in respect of such judgments, damages, losses, claims, liabilities, fines, penalties or amounts paid in settlement) resulting therefrom. The indemnification obligations of the Surviving Corporation pursuant to this Section 5.6(a) shall extend to acts or omissions occurring at or before the Effective Time and any Claim relating thereto (including with respect to any acts or omissions occurring in connection with the approval of this Agreement and the consummation of the transactions contemplated hereby and any Claim relating thereto) and all rights to indemnification conferred hereunder shall continue as to an individual who has ceased to be a director or officer of the Company or any of its Subsidiaries prior to the Effective Time and shall inure to the benefit of such individual’s heirs, executors and personal and legal representatives. As used in this Section 5.6(a), the term “Claim” means any threatened, asserted, pending or completed claim, action, suit or proceeding, or any inquiry or investigation, whether instituted by the Company, any Governmental Authority or any other party, whether civil, criminal, administrative, investigative or other, including any arbitration or other alternative dispute resolution mechanism, arising out of or pertaining to matters that relate to such Indemnified Party’s duties or service as a director, officer, trustee, employee, agent, or fiduciary of the Company, any of its Subsidiaries, any employee benefit plan maintained by any of the foregoing at or prior to the Effective Time and any other Person at the request the Company or any of its Subsidiaries.

(b) From and after the Effective Time, the Surviving Corporation shall keep in full force and effect, and comply with the terms and conditions of, any agreement in effect as of the date of this Agreement between or among the Company or any of its Subsidiaries and any Indemnified Party and listed in Section 2.19 of the Company Disclosure Schedule providing for the indemnification of such Indemnified Party.

(c) If the Surviving Corporation or any of its successors or assigns shall (i) consolidate with or merge into any other Person and shall not be the continuing or surviving Person of such consolidation or merger or (ii) transfer all or substantially all of its properties and assets to any Person, then, in each such case, proper provisions shall be made so that the successors and assigns of Parent and the Surviving Corporation, assume all of the obligations of the Surviving Corporation set forth in this Section 5.6.

(d) From and after the Effective Time, the Surviving Corporation, together with any insurance policies held by the Surviving Corporation or any of its Subsidiaries on behalf of the Company, any of its Subsidiaries or any of their respective directors and officers, shall be the indemnitor of first resort with respect to any Claim, responsible for all indemnification and advancement of expenses contemplated by this Section 5.6 without regard to any right to indemnification or advancement of expenses that any Indemnified Party may have from any direct or indirect stockholder of the Company (or any affiliate of such stockholder), and without right to seek subrogation, indemnity or contribution.

(e) The provisions of this Section 5.6 shall survive the consummation of the Merger for a period of six (6) years and (i) are intended to be for the benefit of, and shall be enforceable by, each Indemnified Party and his or her heirs and representatives and (ii) are in addition to, and not in substitution for, any other rights to indemnification or contribution that any such Person may have by contract or otherwise. The obligations of Parent or the Surviving Corporation under this Section 5.6 shall not be terminated or modified in such a manner as to adversely affect the rights of any Indemnified Party under this Section 5.6 without the consent of such affected Indemnified Party.

(f) Notwithstanding anything to the contrary set forth herein, the Company may, prior to or in connection with the Closing, purchase a “tail” policy under the Company’s existing directors’ and officers’ insurance policy (the “Tail Policy”), with the cost of such Tail Policy, to the extent unpaid as of the Closing, included in the Company Transaction Expenses.

Section 5.7 Takeover Statutes. If any Takeover Statute is or may become applicable to the transactions contemplated hereby, the Company Board shall grant such approvals and take such actions as are necessary so that the transactions contemplated hereby may be consummated as promptly as practicable on the terms contemplated hereby and otherwise act to eliminate the effects of any Takeover Statute on any of the transactions contemplated hereby.

Section 5.8 Tax Matters. The following provisions shall govern the allocation of responsibility as among Parent and the Stockholders’ Agent for certain Tax matters:

(a) Pre-Closing Tax Period and Straddle Period Tax Returns. Parent shall prepare or cause to be prepared and file or cause to be filed all Tax Returns for the Company and its Subsidiaries for any taxable year or period that ends on or before the Closing Date that are due (including extensions) after the Closing Date and for any Straddle Period in a manner that is consistent with the past practices, procedures and accounting methods of the Company and its Subsidiaries except to the extent such past practices, procedures and accounting methods are determined not to be permissible under the applicable Legal Requirements. Parent shall (A) submit such Tax Returns to the Stockholders’ Agent for review and comment at least twenty (20) days prior to their filing and (B) make any timely comments requested by the Stockholders’ Agent in good faith, provided such comments are (i) consistent with past practice and applicable Legal Requirements, and (ii) could not reasonably be expected to materially adversely impact the Company, any of its Subsidiaries or Parent (or any Affiliate) in any taxable year or period beginning after the Closing Date. Parent shall receive a disbursement from the Escrow Fund, at least five (5) days before the due date of the applicable Tax Return, in an amount equal to the Taxes shown as due and payable on such Tax Return to the extent such Taxes are due with respect to the Tax liability of the Company or any of its Subsidiaries for taxable years ending on or before the Closing Date and the portion of any Straddle Period ending on (and including) the Closing Date. In the event that Parent and the Stockholders’ Agent are unable to agree on any position(s) taken on any Tax Return described in this Section 5.8(a) prior to the due date for filing such Tax Return, Parent and the Stockholders’ Agent shall promptly submit such Tax Return to the Tax Arbitrator for resolution in accordance with the procedures described in Section 5.8(d); provided, however, that if the Tax Arbitrator is unable to resolve such dispute prior to the filing of such Tax Return, Parent shall be entitled to receive a disbursement from the Escrow Fund or, if after the release date of the Escrow Fund, payment from the Indemnifying Persons in accordance with this Section 5.8(a) and ARTICLE VIII for the amount of Taxes for taxable periods ending on or before the Closing Date and the portion of any Straddle Period ending on (and including) the Closing Date shown as due and payable on the Tax Return originally submitted to the Stockholders’ Agent by Parent; provided further, however, that if the Tax Arbitrator resolves such dispute in favor of the Stockholders’ Agent, Parent shall prepare and file an amended Tax Return reflecting the position of the Tax Arbitrator with respect to the disputed item or items and, within five (5) days of receipt of any refund or credit of Taxes attributable to such disputed item or items, pay to the Escrow Fund or, if after the release date of the Escrow Fund, the Indemnifying Persons, the amount of such refund or credit plus any interest received with respect thereto from the applicable Governmental Authority (net of any Taxes imposed on such refund amount, including interest). In the event that any such Tax refund is subsequently reduced as a result of any adjustment required by any Governmental Authority, Parent shall be entitled to receive a disbursement from the Escrow Fund or payment from the Indemnifying Persons in accordance with this Section 5.8(a) for the amount of such reduction. Taxes shall be apportioned as provided in Section 5.8(c).

(b) Tax Contests. After the Closing Date, Parent shall notify the Stockholders’ Agent within ten (10) days of the commencement of any notice of Tax deficiency, proposed Tax adjustment, Tax assessment, Tax audit, Tax examination or other administrative or court proceeding, suit, dispute or other claim with respect to Taxes (a “Tax Claim”) affecting the Taxes of or with respect to the Company or any of its Subsidiaries that, if determined adversely to the taxpayer or after the lapse of time would be grounds for a claim for indemnity pursuant to Section 8.2(a) hereof; provided, however, that a failure by Parent to provide notice of a Tax Claim within such ten (10) day period shall not entitle the Indemnifying Persons to reduce the amount of the liability required to be paid pursuant to the Tax Indemnity under Section 8.2(a) unless such failure results in a material detriment to the Indemnifying Persons, in which case the amount the Indemnifying Persons are required to pay with respect to such liability shall only be reduced by the amount of such detriment. Thereafter, Parent shall deliver to the Stockholders’ Agent, as promptly as possible but in no event later than ten (10) days after Parent’s receipt thereof, copies of all relevant notices and documents (including court papers) received by Parent. In the case of any Tax Claim relating to any Tax period ending on or before the Closing Date that, if determined adversely to the Company or any of its Subsidiaries would be grounds for a claim for indemnity pursuant to Section 8.2(a) hereof, the Stockholders’ Agent (at its sole cost and expense) shall have the right to control the conduct of such Tax Claim and shall have the right to settle such Tax Claim; provided, however, (i) that Parent may fully participate in the dispute of such Tax Claim, (ii) the Stockholders’ Agent shall not settle, compromise or dispose of any Tax Claim in a manner that could reasonably be expected to adversely affect the Company, any of its Subsidiaries, Parent or its affiliates after the Closing Date, (iii) the Stockholders’ Agent shall keep Parent timely informed with respect to the commencement, status and nature of any such Tax Claim and (iv) the Stockholders’ Agent shall not settle, compromise or dispose of any Tax Claim without the consent of the Parent, which consent shall not be unreasonably withheld. In the case of any Tax Claim relating to the Taxes of any Straddle Period, Parent and the Stockholders’ Agent may each participate, at their own expense, in the audit or proceeding, and the audit or proceeding shall be controlled by Parent or the Stockholders’ Agent, whichever would bear the burden of the greatest portion of the adjustment; provided, however, that the party controlling the Straddle Period Tax Claim (i) shall not settle such audit or proceeding without the consent of the other party, which consent shall not be unreasonably withheld and (ii) shall keep the other party timely informed with respect to the commencement, status and nature of any such Tax Claim.

(c) Where it is necessary for purposes of this Agreement to apportion the Taxes of the Company or any of its Subsidiaries or with respect to the assets of the Company or any of its Subsidiaries for a Straddle Period, such liability shall be apportioned between the period deemed to end at the close of the Closing Date, and the period deemed to begin at the beginning of the day following the Closing Date on the basis of an interim closing of the books, except that Taxes (such as real or personal property Taxes) imposed on a periodic basis shall be allocated on a daily basis.

(d) Cooperation. Parent and the Stockholders’ Agent shall cooperate fully, as and to the extent reasonably requested by the other party, in connection with the filing of Tax Returns and any audit, examination, litigation or other proceeding with respect to Taxes. Such cooperation shall include the retention and (upon the other party’s request) the provision of records and information which are reasonably relevant to any such audit, litigation or other proceeding. Each of Parent and the Stockholders’ Agent agrees, upon request, to use its reasonable best efforts to obtain any certificate or other document from any Tax Authority as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed (including, but not limited to, with respect to the transactions contemplated hereunder).

(e) Dispute Resolution. Any dispute, controversy, or claim between Parent, on the one hand, and the Stockholders’ Agent, on the other hand, arising out of or relating to the provisions of this Agreement that relates to Taxes or any Tax Returns that cannot be resolved by negotiations between Parent and the Stockholders’ Agent shall be submitted to a senior tax partner in a mutually agreeable nationally recognized accounting firm for resolution (“Tax Arbitrator”). Parent and Stockholders’ Agent shall instruct the Tax Arbitrator to decide any matter that would be expected to result in an indemnification obligation under Section 8.2(a) that comes before such Tax Arbitrator in a manner that is consistent with past practices, procedures and accounting methods of the Company and its Subsidiaries except to the extent such past practices, procedures and accounting methods are determined not to be permissible under the applicable Legal Requirements. The resolution reached by the Tax Arbitrator shall be binding on the Company, its Subsidiaries, the Stockholders’ Agent, Parent and their respective affiliates, and may be entered and enforced in any court having jurisdiction. The expenses of the Tax Arbitrator shall be borne by Parent and the Stockholders’ Agent in such proportions as the Tax Arbitrator considers to be fair and reasonable in all circumstances to resolve the dispute.

Section 5.9 Parachute Payment Waivers. The Company shall use commercially reasonable efforts to obtain and deliver to Parent, prior to the initiation of the requisite stockholder approval procedure under Section 5.10, a parachute payment waiver, in substantially the form attached hereto as Exhibit D (the “Parachute Payment Waiver”), from each person who the Company reasonably believes is, with respect to the Company, and/or any ERISA Affiliate, a “disqualified individual” (within the meaning of Section 280G of the Code and the regulations promulgated thereunder), as determined immediately before the initiation of the requisite stockholder approval procedure under Section 5.10 and who might otherwise have, receive or have the right or entitlement to receive a parachute payment under Section 280G of the Code as a result of (a) the accelerated vesting of stock options or unvested property in connection with the Merger and/or the termination of employment or service with the Company, the Surviving Corporation or Parent before, upon or following the Merger, (b) any severance payments, bonus payments or other benefits or payments in connection with the Merger and/or the termination of employment or service with the Company, the Surviving Corporation or Parent before, upon or following the Merger and/or (c) the receipt of any Company Options or Company Common Stock within the 12-month period ending on the date the Effective Time occurs, pursuant to which such person shall agree to waive any and all right or entitlement to the accelerated vesting, payments, benefits options and stock referred to in clauses (a), (b) and (c) to the extent the value thereof exceeds 2.99 times such person’s base amount determined in accordance with Section 280G of the Code and the regulations promulgated thereunder, unless the requisite stockholder approval of such accelerated vesting, payments, benefits, options and stock is obtained pursuant to Section 5.10.

Section 5.10 280G Stockholder Approval. The Company shall use its commercially reasonable efforts to obtain the approval by such number of stockholders of the Company as is required by the terms of Section 280G(b)(5)(B) of the Code so as to render the parachute payment provisions of Section 280G of the Code inapplicable to any and all accelerated vesting payments, benefits, options and/or stock provided pursuant to the agreements, contracts or arrangements that might otherwise result, separately or in the aggregate, in the payment of any amount and/or the provision of any benefit that would not be deductible by reason of section 280G of the Code, with such stockholder vote to be obtained in a manner which satisfied all applicable requirements of Section 280G(b)(5)(B) of the Code and the regulations promulgated thereunder.

Section 5.11 Treatment of Certain Indebtedness.

(a) On or prior to the fifth (5th) Business Day prior to the Closing, the Company shall obtain a payoff letter from the agent under that certain Credit Agreement, dated as of August 26, 2009, among the Company, US Oncology, Inc., the Lenders party thereto, Deutsche Bank Trust Company Americas, as Administrative Agent and Collateral Agent, Morgan Stanley Senior Funding, Inc. and Wells Fargo Bank, N.A., as Syndication Agents, and JPMorgan Chase Bank, N.A. as Documentation Agent (the “Company Credit Agreement”), in customary form reasonably acceptable to Parent, with respect to the Indebtedness of the Company and its Subsidiaries under such Company Credit Agreement which payoff letter shall (i) indicate the total amount required to be paid to fully satisfy all principal, interest, prepayment premiums, penalties, breakage costs or similar obligations related to such Indebtedness as of the Closing Date (the “Payoff Amount”), (ii) indicate the total face amount of Company LCs and (iii) state that all liens in connection therewith relating to the assets of the Company or any Subsidiary of the Company shall be, upon the payment of the Payoff Amount on the Closing Date and the replacement of the Company LCs or the issuance of Parent LCs, as provided below, released (the payoff letter described in this sentence being referred to as the “Payoff Letter”). The Company shall, and shall cause its Subsidiaries to, deliver all notices and take all other actions reasonably requested by Parent, or otherwise necessary, to facilitate (i) the termination of commitments under the Company Credit Agreement, the repayment in full of all obligations then outstanding thereunder and the release of all liens in connection therewith on the Closing Date and (ii)(x) the replacement of all letters of credit issued for the account of the Company or any of its Subsidiaries under the Company Credit Agreement (the “Company LCs”) with letters of credit issued and outstanding under Parent’s credit facilities (the “Parent LCs”), or (y) if it is impracticable to replace the Company LCs, the issuance to the letter of credit issuer under the Company Credit Agreement of “back to back” letters of credit under Parent’s credit facilities, in a face amount equal to the face amount of the Company LCs, which letters of credit provided by Parent shall be for the sole purpose of reimbursing the letter of credit issuer under the Company Credit Agreement for drawings made on the Company LCs, plus accrued interest and fees thereon, effective as of the Closing Date (such

termination, repayment, release and replacement or issuance, the “Credit Agreement Termination”). Concurrently with the Closing, Parent shall pay to the administrative agent under the Company Credit Agreement all amounts required pursuant to the terms of the Company Credit Agreement and specified in the Payoff Letter to effect the Credit Agreement Termination.

Notwithstanding anything herein to the contrary, the Company shall not be required to cause a Trustee to send any notice of redemption until the Company receives an officer’s certificate from Parent that each condition to Parent and Merger Sub’s obligation to consummate and affect the Merger and the transactions contemplated hereby set forth in ARTICLE VI (other than Section 6.3(l)) have been satisfied and that Parent and Merger Sub will do so subject only to satisfaction of the conditions set forth in Section 6.3(l).

(d) In determining the existence of a breach or the amount of any Damage, any qualifications in the representations, warranties and covenants with respect to a Material Adverse Effect, materiality, material or similar terms shall be disregarded and will not have any effect with respect to the calculation of the amount of any Damages attributable to a breach of any representation, warranty or covenant of the Company set forth in this Agreement or in any of the Ancillary Agreements, exhibits, schedules or certificates to, or delivered in connection with this Agreement.

(e) The representations and warranties of the Company contained in this Agreement (and claims for breach of a Representation Covenant related to such representations and warranties) other than the Specified Representations (and claims for breach of a Representation Covenant related to such Specified Representations) shall survive until the date eighteen (18) months after the Closing Date, and no claims for indemnification pursuant to Section 8.2(a)(i) may be brought after such date with respect to such representations and warranties (or such Representation Covenant).

No claims for indemnification pursuant to Sections 8.2(a)(ii)-(v) or (vii) may be made after the date that is three (3) years after the Closing Date.

Section 8.4 Stockholders’ Agent.

The Stockholders’ Agent shall be entitled to engage such counsel, experts and other agents and consultants as it shall deem necessary in connection with exercising its powers and performing its function hereunder and shall be entitled to conclusively rely on the opinions and advice of such Persons. The Indemnifying Persons shall severally and pro rata, in accordance with their respective Proportionate Indemnification Share, indemnify the Stockholders’ Agent and hold him harmless against any loss, liability or expense incurred without gross negligence or bad faith on the part of the Stockholders’ Agent and arising out of or in connection with the acceptance or administration of his duties hereunder (the “Agent Expenses”). The Stockholders’ Agent shall be entitled to receive out of the Stockholders’ Agent Reimbursement Escrow Amount such amounts as may be necessary to reimburse the Stockholder’s Agent for any Agent Expenses. In addition, following the termination of the Escrow Period, the Stockholders’ Agent shall have the right to recover Agent Expenses from the Escrow Fund from any amount that would otherwise be distributed to the Indemnifying Persons and, prior to any such distribution, shall deliver to the Escrow Agent a certificate setting forth the Agent Expenses actually incurred.

Section 8.5 Actions of the Stockholders’ Agent. A decision, act, consent or instruction of the Stockholders’ Agent shall constitute a decision of all of the Indemnifying Persons and shall be final, binding and conclusive upon each and every Company Holder, and the Escrow Agent, Parent, Merger Sub, the Company and the Surviving Corporation may rely upon any decision, act, consent or instruction of the Stockholders’ Agent as being the decision, act, consent or instruction of each and every Company Holder. The Escrow Agent and Parent are hereby relieved from any liability to any Person for any acts done by them in accordance with such decision, act, consent or instruction of the Stockholders’ Agent.

Section 8.6 Third-Party Claims. Except as otherwise provided in Section 5.6(b), in the event that Parent becomes aware of a third-party claim (“Third Party Claim”) which Parent believes may result in an indemnification obligation under this ARTICLE VIII, Parent shall promptly notify the Stockholders’ Agent of such Third Party Claim; provided, however, that the failure to give prompt notice shall not affect the indemnification provided hereunder except to the extent the Stockholders’ Agent, on behalf of the Indemnifying Persons, has been actually prejudiced as a result of such failure. The notice of Third Party Claim shall include, based on the information then available to Parent, a summary in reasonable detail of the basis for the Third Party Claim. The Stockholders’ Agent, on behalf of the Indemnifying Persons, shall, at its expense and without recourse to the Escrow Fund, be entitled to participate in any defense of such Third Party Claim; provided, however, that Parent shall have full control over the Third Party Claim, including settlement and compromise thereof (other than any settlement or compromise that would expose any director or officer of the Company or any of its Subsidiaries to individual liability or criminal sanctions); provided, further, that notwithstanding anything in this Agreement to the contrary, no Parent Indemnified Person shall settle or compromise any Third Party Claim or permit a default or consent to entry of any judgment with respect any Third Party Claim, and the Indemnifying Persons will not be bound by the entry of any such settlement or compromise effected or any such judgment consented to, without the prior written consent of the Stockholders’ Agent (which consent will not be unreasonably withheld, conditioned or delayed,

provided that in connection with any Third Party Claim that may arise from any lawsuit, action, proceeding, claim, complaint, subpoena, investigation or dispute, in each case, of which the Company has Knowledge as of the date of this Agreement and which is pending or threatened as of the date of this Agreement the Stockholders’ Agent may only object to a settlement to the extent that Parent had no reasonable basis to agree to the settlement based on the facts and circumstances known at the time); provided, further, that the Stockholders’ Agent shall be deemed not to have objected to any settlement of any such Third Party Claims unless the Stockholders’ Agent shall have objected in writing to Parent within twenty (20) days after the Stockholders’ Agent receipt of a written notice from Parent of such proposed or actual settlement. The Escrow Agent shall not disburse any portion of the Escrow Fund to any third party except in accordance with joint written instructions received from Parent and the Stockholders’ Agent. In the event that the Stockholders’ Agent has failed to timely object to any such settlement, neither the Stockholders’ Agent nor any Indemnifying Person shall have any power or authority to object under the Escrow Agreement or any provision of this ARTICLE VIII to any claim by any Parent Indemnified Person for indemnity in the amount of such settlement, together with related Damages.

Neither the Stockholders’ Agent nor any Company Holder shall make any claim for contribution from the Company, the Surviving Corporation, any of its Subsidiaries or any of their respective officers, directors or employees with respect to any indemnity claims arising under or in connection with this Agreement to the extent that the Company, Surviving Corporation or any Indemnified Person is entitled to indemnification hereunder for such claim, and the Stockholders’ Agent, on its own behalf and on behalf of all Indemnifying Persons, hereby waives any such right of contribution from the Company, the Surviving Corporation, any of its Subsidiaries and any of their respective officers, directors or employees it has or may have in the future.

Section 8.8 Effect of Investigation; Reliance. The right to indemnification, payment of Damages or any other remedy will not be affected by any investigation conducted with respect to, or any knowledge acquired (or capable of being acquired) at any time, whether before or after the execution and delivery of this Agreement or the Closing Date, with respect to the accuracy or inaccuracy of or compliance with, any representation, warranty, covenant or agreement made by the Company or any other matter. The waiver of any condition based on the accuracy of any such representation or warranty, or on the performance of or compliance with any such covenant or agreement, will not affect the right to indemnification, payment of Damages, or any other remedy based on any such representation, warranty, covenant or agreement. No Parent Indemnified Person shall be required to show reliance on any representation, warranty, certificate or other agreement in order for such Parent Indemnified Person to be entitled to indemnification hereunder. Parent and the Company each acknowledge that such Damages, if any, would relate to unresolved contingencies existing at the Effective Time, which if resolved at the Effective Time would have led to a reduction in the Purchase Price that Parent would have paid in connection with the Merger.

Section 8.9 Tax Benefits; Insurance.

(a) The amount of Damages for which a Parent Indemnified Person shall be indemnified pursuant to this ARTICLE VIII shall be determined without regard to any potential reduction in Taxes of such Parent Indemnified Person attributable to the Damages that gave rise to indemnification. If and to the extent that there is any Tax Benefit Actually Realized for taxable periods of Parent and its affiliates ending on or before the date that is three (3) years after the Closing by the relevant Parent Indemnified Person, Parent shall, no later than 30 days after the Parent Indemnified Person Actually Realizes such Tax Benefit, pay or cause to be paid the amount of such Tax Benefit Actually Realized to the Stockholder’s Agent for the benefit of the Indemnifying Persons, provided, however, that Parent shall not be required to make any payment in excess of the indemnification payment or payments actually received by the Parent Indemnified Person.

(b) For purposes of Section 8.9(a):

(i) The term “Tax Benefit Actually Realized” shall mean an actual reduction in the amount of Taxes paid or payable by the relevant Parent Indemnified Person, determined by comparing (x) the amount of Taxes actually owed by the relevant Parent Indemnified Person and (y) the amount of Taxes that would have been owed without regard to any Tax items attributable to the Damages that gave rise to the relevant indemnification payment.

(ii) For the avoidance of doubt, (a) where a Parent Indemnified Person has other Tax items available to it, the Tax items attributable to such Damages shall be treated as the last Tax items used and (b) the amount of a Tax Benefit shall be determined taking into account (i) all increases in federal, state, local or other taxes (including estimated taxes) payable by the applicable Parent Indemnified Person as a result of the receipt of any indemnity payment (e.g., as a result of the indemnity payment being included in income, resulting in a reduction of tax basis, or otherwise), and (ii) to the extent not previously taken into account in computing the amount of the relevant Damages, all increases in federal, state, local or other taxes (including estimated taxes) payable by the Parent Indemnified Person as a result of the indemnified event.

(iii) In the event that, following any payment by Parent pursuant to this Section 8.9, there is any reduction in any Tax Benefit Actually Realized as a result of a Parent Indemnified Person subsequently realizing a deduction, loss, credit or other item that can be carried back or forward to any year in which a Tax Benefit previously was Actually Realized or any Tax authority requires any adjustment that results in the reduction of any Tax Benefit in respect of which Parent has made a payment under Section 8.9(a), the Indemnifying Persons shall promptly pay to Parent the amount of such reduction plus interest calculated at the appropriate applicable federal rate from the date that Parent first paid such amount to the to the Stockholder’s Agent for the benefit of the Indemnifying Persons.

(c) The calculation of any Damages under this ARTICLE VIII will reflect the amount of any insurance proceeds received in cash by the Parent Indemnified Persons in respect of such Damage, net of the present value of any reasonably probable increase in insurance premiums or other charges paid or to be paid by the Parent Indemnified Persons resulting from such Damage and all costs and expenses, including attorneys fees and expenses, incurred by any Parent Indemnified Persons in recovering such proceeds from its insurers.
