(c) in all material respects, all obligations required to be performed prior to the date hereof under the Contracts by the parties thereto have been performed, and no event has occurred or failed to occur which constitutes, or with the giving of notice, the lapse of time or both would constitute, a default by a Partnership under one of the Contracts;

(d) no Contract prohibits or requires the consent of any Person to the transfer of the Partnership Interests by Seller to Buyer;

(e) no Contract will prohibit competition or restrict the ability of a Partnership to engage in any lawful business after Closing (including diagnostic imaging centers); and

3.18. Related-Party Transactions. Schedule 3.18 describes all goods or services purchased, acquired or leased from, or sold, transferred or leased to, any Affiliate of Seller, or any partner, Affiliate, officer, employee or other agent of Seller or of any Affiliate of Seller, since December 31, 2002.

All such litigation, arbitration, mediations, investigations and other material claims, actions or proceedings pending against the Partnerships are fully insured (except for applicable deductibles and other policy limits) and no insurer has issued a “reservation of rights” letter or otherwise qualified its obligation to insure and defend the Partnerships against losses arising therefrom. Except as set forth on Schedule 3.21, there are no litigation, arbitration, mediations, investigations, or other material claims, actions or proceedings (including qui tam actions) pending or, to Seller’s knowledge threatened, against the Partnerships. To Seller’s knowledge, there exist no facts that might reasonably be expected to form the basis of any such litigation, arbitration, mediation, investigation, or other material claim, action or proceeding.

3.22. Taxes.

(a) Each Partnership has filed all material Tax Returns required to be filed by or on behalf of it, all such Tax Returns are correct and complete in all material respects,

and the Partnership has duly paid or made provision in the Financial Statements for the payment of all Taxes; no claim has ever been made by a Governmental Authority in a jurisdiction where a Partnership does not file Tax Returns that it is or may be subject to Tax by that jurisdiction; and there are no Encumbrances on any Partnership assets that arose in connection with any failure (or alleged failure) to pay any Tax.

(b) Each Partnership has withheld and paid, or caused to be withheld and paid, all Taxes on monies paid by the Partnership to independent contractors, creditors and other Persons for which withholding or payment is required by law.

(c) To Seller’s knowledge, no Governmental Authority intends to assess any additional Taxes for any period for which Tax Returns have been filed. There is no dispute or claim concerning any Tax liability of any Partnership either claimed or raised by any Governmental Authority in writing, or as to which Seller has notice or knowledge based upon personal contact with any agent of such authority; Schedule 3.22 lists all federal, state, local and foreign income Tax Returns filed with respect to the Partnerships for the last three complete fiscal years of the Partnerships and for the current year-to-date, and indicates those Tax Returns that have been audited and those that currently are the subject of audit or that have not been audited.

(e) No Partnership is a party to any Tax allocation or sharing Contract; no Partnership is or has been a member of any affiliated group (within the meaning of section 1504 of the Code or any similar group defined under a similar provision of state, local or foreign law) for filing a consolidated federal income Tax Return.

(f) No Partnership has or will have any liability for the Taxes of any Person (other than under Internal Revenue Service regulation 1.1502-6 or any similar provision of state, local or foreign law), as a transferee or successor, by Contract or otherwise.

(g) No Person has (i) provided tax advice to Seller or Radiologix in connection with the transactions contemplated by this Agreement, and (ii) limited (expressly or otherwise) Seller’s or Radiologix’s ability to disclose the tax treatment or tax structure of, and such advisor’s tax strategies with respect to, the transactions contemplated by this Agreement, and (iii) received (or is expected to receive) a fee of at least $250,000.

a receiver or trustee of all or any portion of Seller’s property; and, to Seller’s knowledge, no other Person has filed or threatened to file such a petition against Seller. The Purchase Price, as adjusted, constitutes the fair market value of and adequate consideration for the Partnership Interests sold by Seller to Buyer.

3.25. Operation of the Centers. Except for the Accounts Receivable which are being transferred to Seller at Closing, and except for the assets described in the last sentence of this Section, the assets and properties owned by each Partnership constitute all assets, properties, goodwill and businesses necessary to operate each Center in all material respects in the manner in which it has been operated since December 31, 2002. Schedule 3.25 sets forth a list of the ten largest non-governmental payors of the Centers, determined on the basis of gross revenues from services provided for the fiscal year ended December 31, 2003. No non-governmental payor has terminated or curtailed its business relationship with or reduced reimbursement rates to the Centers which has resulted in a Material Adverse Effect on the Centers, and neither Seller nor any Partnership has received any notice to the effect that any such non-governmental payor intends to terminate or curtail its business relationship with or reduce reimbursement rates to the Centers which could reasonably be expected to result in a Material Adverse Effect on the Centers. Buyer acknowledges that, as more particularly described in the Related Agreement, the following assets used in the conduct of Seller’s business are not assets of the Partnerships to be acquired by Buyer: all assets used solely in the conduct of Seller’s physician practice management business; the tele-radiology system of Seller; and computer hardware and software owned or leased by Seller that is primarily utilized to conduct patient satisfaction surveys.

5.05. Post-Closing Maintenance of and Access to Information and Assistance.

(a) The Parties acknowledge that after Closing each Party may need access to information or documents in the control or possession of another Party for the purposes of concluding the transactions herein contemplated, billing and collecting Accounts Receivable, preparing Tax Returns or conducting Tax audits, obtaining insurance, complying with the Government Payment Programs and other Legal Requirements, and prosecuting or defending third party claims. Accordingly, each Party shall maintain in the ordinary course of business and release all books, records (including patient medical records), documents and other information in the possession or control of such Party in accordance with all applicable Legal Requirements (including the Health Insurance

Portability and Accountability Act, 42 U.S.C. 1320d et seq.) and record retention policies.

(b) Each Party shall cooperate fully with, and make available for inspection and copying by, the other Party, its employees, agents, counsel and accountants and/or Governmental Authorities, upon written request and at the expense of the requesting Party, such books, records documents and other information to the extent reasonably necessary to facilitate the foregoing purposes. In addition, each Party shall cooperate with, and shall permit and use its best efforts to cause its former and present directors, officers and employees to cooperate with, the other Party on and after Closing in furnishing information, evidence, testimony and other assistance in connection with any action, proceeding, arrangement or dispute of any nature with respect to the subject matters of this Agreement.

(c) Upon Buyer’s receipt of any required consents and authorizations, Seller shall be entitled to remove from the Centers, at Seller’s sole risk and expense, any patient or other records that relate to events or periods prior to Closing for purposes of pending litigation involving matters to which such records refer, as certified in writing prior to removal by counsel retained by Seller in connection with such litigation. Any records so removed from the Centers shall be promptly returned to Buyer following their use by Seller.

(d) San Antonio Partners and Buyer shall take all actions reasonably necessary or desirable to assist Seller in Seller’s efforts to collect the Accounts Receivable, including promptly forwarding telephone calls, written correspondence and other communications regarding the Accounts Receivable of the Partnerships transferred to Seller that are directed or addressed to the Partnerships, Seller or its collection agent, provided that neither San Antonio Partners nor Buyer shall act as Seller’s agent in connection with the collection of the Accounts Receivable nor be required to commence or prosecute any legal action in any forum to assist in their collection.

(e) The exercise by any Party of any right of access granted herein shall not materially interfere with the business operations of the other Party and nothing in this Section shall require any Party to maintain or release to any other Persons any medical or other records except in accordance with applicable Legal Requirements and record retention policies.

5.06. Governmental Authority Approvals; Consents to Assignment.

(a) From the Effective Date until the Closing Date, each of Seller and Buyer shall (i) promptly apply for and use its reasonable best efforts to obtain prior to Closing all consents, approvals, authorizations and clearances of Governmental Authorities required of it to consummate the transactions contemplated hereby, (ii) provide such information and communications to Governmental Authorities as the other Party or such Persons may reasonably request, and (iii) assist and cooperate with other Parties to obtain all consents, licenses, permits, approvals, authorizations and clearances of Governmental Authorities that the other Parties reasonably deem necessary or appropriate, and to prepare any document or other information reasonably required of it by any such Persons to consummate the transactions contemplated herein, provided that, notwithstanding the foregoing, no Party shall have any obligation under such provisions (x) to pay any cash amounts to Governmental Authorities other than filing fees, or (y) to agree to divest assets or limit the operations of its businesses.

(b) The Parties acknowledge that they are not required to file a Notification and Report Form under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, concerning the transactions contemplated by this Agreement.

(c) In order to obtain any one or more of the consents and approvals described in this Section, Buyer or the Partnership may be required by applicable Legal Requirement or practical necessity to enter into a new Contract with the Governmental Authority or other party to a Contract that supercedes the existing Contract between the Partnership and such other Person. Such new Contract may require Buyer or the Partnership to assume for the benefit of such Person certain obligations and liabilities of the Partnerships that are Excluded Liabilities or against which Seller and San Antonio Partners are to indemnify or otherwise reimburse Buyer. Alternatively, Buyer may be required by Legal Requirement to assume, or be deemed by Legal Requirement to have assumed, obligations and liabilities of the Partnership that are Excluded Liabilities. If Buyer enters into any such Contract with any such Person or by Legal Requirement assumes such obligations or liabilities of a Partnership, such Contract or assumption shall not in any manner whatsoever be deemed to amend or modify this Agreement or to impair Buyer’s rights to indemnification against Seller and San Antonio Partners or diminish Seller’s and San Antonio Partner’s indemnity obligations to Buyer under this Agreement and shall under no circumstances be claimed by Seller or San Antonio Partners as a defense (whether of waiver, estoppel, consent, operation of law, or otherwise) against Buyer’s assertion of any claim under this Agreement against Seller and San Antonio Partners, and the rights and obligations of the Parties to each other under this Agreement shall be determined as if such Contract with such Governmental Authority or other party to a Contract did not exist or such assumption was not required. For all other purposes in this Agreement, the requirement that Buyer or the Partnership enter into a new Contract shall be treated the same as an assignment of the existing Contract.

5.07. Noncompetition.

(a) For a period of five years from and after the Closing Date, neither Radiologix nor any direct or indirect subsidiary of Radiologix shall, directly or indirectly, in any capacity:

(i) own, lease, manage, operate, control, participate in the management or control of, be employed by, or maintain or continue any interest whatsoever in any Person engaged in the business of providing diagnostic imaging services within a 25-mile radius of any of the Centers; or

(ii) induce, cause or attempt to induce or cause any Person (including any physician employee or medical staff member) to replace or terminate any Contract for the provision or arrangement of health care services from the Centers with products or services of any other Person at any time after the Closing Date.

(b) Notwithstanding the foregoing, it shall not be a violation of paragraph (a)(i) of this Section for Radiologix, or any direct or indirect subsidiary of Radiologix to acquire one or more Persons engaged in the business of providing diagnostic imaging services within the 25-mile radii described above so long as such Persons were acquired as a part of a larger transaction in which (i) the consideration allocated to the Persons engaged in the business of providing diagnostic imaging services within the 25-mile radii is less than ten percent of the total consideration necessary to consummate the larger transaction and (ii) the net revenues of the Persons engaged in the business of providing diagnostic imaging services within the 25-mile radii are less than ten percent of the consolidated net revenues of all Persons acquired in the larger transaction.

(c) Seller acknowledges that any remedy at law for any breach of this Section would be inadequate and consent to the granting by any court of an injunction or other equitable relief, without the necessity of actual monetary loss being proved, in order that a breach or threatened breach of this Section may be effectively enjoined.

(d) For purposes of this Section, a direct or indirect subsidiary of Radiologix shall include any Person whose financial results are, or are required by generally accepted accounting principles to be, consolidated with the financial results of Radiologix.

5.08. Allocation of Purchase Price. The Purchase Price shall be allocated among the Partnership Interests as set forth on Schedule 5.08, and such allocation shall be binding upon the Parties for all applicable federal, state, local and foreign Tax purposes. Seller and Buyer shall report gain or loss or cost basis, as the case may be, in a manner consistent with such allocation on all Tax Returns filed by any of them after Closing and not voluntarily take any inconsistent position therewith in any administrative or judicial proceeding relating to such returns. Seller will treat the sale of the Partnership Interests for federal income tax purposes as a sale of partnership interests. Seller will prepare and file the Partnership’s final tax returns.

5.09. Further Assurances. At any time and from time to time at and after the Closing, upon request of Buyer, Seller shall do, execute, acknowledge and deliver, or cause to be done,

executed, acknowledged and delivered, such further acts, deeds, assignments, transfers, conveyances, powers of attorney, confirmations and assurances as Buyer may reasonably request to more effectively convey, assign and transfer to and vest in Buyer, its successors and assigns, full legal right, title and interest in and actual possession of the Partnership Interests and the assets and properties of the Partnerships, to confirm Seller’s capacity and ability to perform its post-Closing covenants and agreements under this Agreement and the Closing Documents, and to generally carry out the purposes and intent of this Agreement. Seller shall also furnish Buyer with such information and documents in its possession or under its control, or which Seller can execute or cause to be executed, as will enable Buyer to prosecute any and all petitions, applications, claims and demands relating to or constituting a part of the assets and properties of the Partnerships.

5.10. Casualty. If prior to the Closing Date one or more of the Centers is destroyed or damaged by fire, theft, vandalism or other cause or casualty and, as a result thereof, any material part of that Center is rendered prior to the Closing Date unsuitable for its primary intended use, Buyer may terminate this Agreement in its entirety without penalty. Otherwise, Buyer may elect at its option to (i) reduce the Purchase Price by the fair market value of the assets destroyed or damaged (determined as of the date immediately prior to the destruction or damage) or, if greater, by the estimated cost to restore, repair or replace such assets, in which event Seller shall retain all right, title and interest in and to any insurance proceeds payable on account of such destruction or damage, or (ii) consummate the transaction notwithstanding such destruction or damage, in which event Seller shall transfer and assign to Buyer at Closing the insurance proceeds (or the right to receive the insurance proceeds) of any applicable insurance policy plus Seller shall pay to Buyer any deductibles or copayments required under the applicable insurance policy. In the absence of an agreement among the Parties, any reduction in Purchase Price pursuant to this Section shall be determined by an MAI appraiser mutually selected and paid equally by Seller, on the one hand, and Buyer, on the other hand. Notwithstanding the foregoing, to the extent that the Purchase Price is reduced as a result of any cause or casualty described in this Section or Seller is obligated to pay to Buyer any deductible or copayment required under the applicable insurance policies, the amount of such Purchase Price reduction or deductible or copayment payment shall be determined by multiplying (i) the total amount otherwise owed by Seller pursuant to the first sentence of this Section times (ii) the percentage interest of Seller in the Partnership in respect of which the fire, theft, vandalism or other cause or casualty loss occurred.

5.11. Costs and Expenses.

(a) Except as otherwise expressly set forth in this Agreement, all expenses of the preparation of this Agreement and of the purchase of the Partnership Interests set forth herein, including counsel, accounting, brokerage and investment advisor fees and disbursements, shall be borne by the respective Party incurring such expenses, whether or not such transactions are consummated.

(b) Seller shall pay all sales and use Taxes arising out of the transfer of the Partnership Interests by Seller to Buyer, the cost of removing any Encumbrances that are not Permitted Encumbrances and all fees and charges charged by third parties to consent to (i) the assignment of the Partnership Interests from Seller to Buyer, (ii) any “deemed”

assignment or transfer of any Contracts or assets of the Partnerships resulting solely from the assignment of the Partnership Interests from Seller to Buyer, and (iii) the assignment of any other Contracts or assets from Seller or any Affiliate of Seller to Buyer. Buyer shall pay the cost of all environmental, engineering and other professional studies undertaken by Buyer and all fees and charges charged by third parties to consent to any “deemed” assignment or transfer of any Contracts or assets of the Partnerships resulting from the dissolution of the Partnerships, as contemplated by Section 2.02. The cost of the insurance described in Section 5.14 shall be $30,000 and shall be borne equally by Seller and Buyer at Closing.

(c) If either Party incurs legal fees or expenses to enforce or interpret any provision of this Agreement, the prevailing Party will be entitled to recover such legal fees and expenses, including attorney’s fees, costs and necessary disbursements, in addition to any other relief to which such Party shall be entitled.

5.12. Fulfillment of Conditions. Each Party will execute and deliver at Closing each Closing Document that such Party is required by this Agreement to execute and deliver as a condition to Closing, and will take all commercially reasonable steps necessary or desirable and proceed diligently and in good faith to satisfy each other condition to the obligations of the Parties contained in this Agreement, to the extent that satisfaction of such condition is within the control of such Party.

5.13. Release of Encumbrances. Seller shall cause all Encumbrances that are not Permitted Encumbrances to be transferred by Seller to Buyer to be released and discharged at or prior to Closing.

5.14 Professional and General Liability Insurance. For five years from and after the Closing Date, Seller will purchase and/or maintain, for the benefit of Seller, the Partnerships and Buyer, all primary and excess insurance policies in force on the Effective Date which cover the Partnerships or the conduct of their business at the Centers prior to the Closing and which are written on a claims-made insuring basis. If at any time during the five-year period described above, any one or more of the foregoing insurance policies is cancelled or not renewed for any reason, Seller will purchase a replacement policy with similar coverage and policy limits as the insurance policies in force on the Effective Date. Each policy of insurance described in this Section shall name each Center as an additional insured, shall provide that Buyer will be given not less than 30 days’ prior notice of cancellation, non-renewal or reduction in limits of such insurance, and shall otherwise be in form reasonably acceptable to Buyer.

(a) Seller is a limited partnership validly existing under the laws of the State of Delaware with full partnership power to carry on its business as it is now being conducted. Radiologix is a corporation duly incorporated and validly existing in good standing under the laws of the State of Delaware with full corporate power to carry on its business as it is now being conducted. Each of Seller and Radiologix has full power and authority to execute and deliver this Agreement and each of the Closing Documents to which it is a party and to perform its obligations therein. All partnership and corporate proceedings required to be taken by Seller and Radiologix to authorize the execution and delivery of this Agreement and each of the Closing Documents to which it is a party and to authorize the performance of its obligations herein and therein, have all been duly and properly taken.

(b) The execution, delivery and performance of this Agreement and each of the Closing Documents to which Seller or Radiologix is a party does not violate any provision of its limited partnership agreement or articles of incorporation and bylaws, as the case may be.

(c) This Agreement and each of the Closing Documents to which Seller or Radiologix is a party constitutes a valid and binding obligation of such Party, enforceable against Seller or Radiologix in accordance with its terms, subject, as to enforcement of remedies, to (i) applicable bankruptcy, reorganization, insolvency, moratorium or other laws affecting creditors’ rights generally from time to time in effect, (ii) limitations on the enforcement of equitable remedies and (iii) such other qualifications as counsel to the Parties may mutually agree upon.

(d) To such counsel’s knowledge, the consummation of the transactions described in this Agreement will not result in a material violation, breach or default by Seller or Radiologix under any material Legal Requirements.

In rendering such opinion, such counsel may rely upon certificates of governmental officials and may place reasonable reliance upon certificates of officers of Seller and Radiologix.

9.	INDEMNIFICATION

9.01. Indemnification by Seller and San Antonio Partners. Subject to and to the extent provided in this Article, from and after the Closing, Seller and San Antonio Partners shall severally (but not jointly) indemnify, defend and hold harmless Buyer’s Indemnified Persons, and each of them, from and against any Losses incurred or suffered by Buyer’s Indemnified Persons, directly or indirectly, as a result of or arising from:

(a) any inaccuracy of any representation or warranty of Seller, whether or not Buyer’s Indemnified Persons relied thereon or had knowledge thereof, provided that in determining whether there has been any such inaccuracy, any qualification as to materiality included in any representation or warranty shall not be taken into account; and

(b) the nonfulfillment of any covenant, agreement or other obligation of Seller or the Partnerships set forth in this Agreement or in any other agreement or instrument delivered by Seller pursuant to this Agreement.

9.02. Seller’s and San Antonio Partners’ Limitations. San Antonio Partners shall have no liability under Section 9.01(a). Seller shall have no liability under Section 9.01(a) and no claim shall accrue against Seller under Section 9.01(a) (i) if Seller proves that prior to the Effective Date Buyer had actual knowledge of the inaccuracy of such representation or warranty, and (ii) unless and until the total liability of Seller in respect of claims arising under Section 9.01(a) exceeds $100,000 in the aggregate, provided that there shall be no minimum Losses requirement, and liability of Seller shall arise from and after $1.00 of Losses, in respect of Losses resulting from Seller’s intentional misrepresentation or fraud.

9.03. Indemnification by Buyer. Subject to and to the extent provided in this Article, from and after the Closing Date, Buyer shall indemnify, defend and hold harmless Seller’s

Indemnified Persons, and each of them, from and against any Losses incurred or suffered by Seller’s Indemnified Persons, directly or indirectly, as a result of or arising from:

(a) the inaccuracy in any representation or warranty of Buyer, whether or not Seller’s Indemnified Persons relied thereon or had knowledge thereof, provided that in determining whether there has been any such inaccuracy, any qualification as to materiality included in any representation or warranty shall not be taken into account; and

(b) the nonfulfillment of any covenant, agreement or other obligation of Buyer set forth in this Agreement or in any other agreement or instrument delivered by Buyer pursuant to this Agreement.

9.04. Buyer’s Limitations. Buyer shall have no liability under Section 9.03(a) and no claim shall accrue against Buyer under Section 9.03(a) (i) if Buyer proves that prior to Closing Seller had actual knowledge of the inaccuracy of such representation or warranty, and (ii) unless and until the total liability of Buyer in respect of claims arising under Section 9.03(a) exceeds $100,000 in the aggregate, provided that there shall be no minimum Losses requirement, and liability of Buyer shall arise from and after $1.00 of Losses, in respect of Losses resulting from Buyer’s intentional misrepresentation or fraud.

9.05. Notice and Procedure. All claims for indemnification by any Indemnified Party against an Indemnifying Party under this Article shall be asserted and resolved as follows:

(a)(i) If any claim or demand for which an Indemnifying Party would be liable for Losses to an Indemnified Party is alleged or asserted by a Person other than any Buyer’s Indemnified Person or Seller’s Indemnified Person (a “Third Party Claim”), the Indemnified Party shall deliver a Claim Notice with reasonable promptness to the Indemnifying Party, together with a copy of all papers served, if any, and specifying the nature of and alleged basis for the Third Party Claim and, to the extent then feasible, the alleged amount or the estimated amount of the Third Party Claim. If the Indemnified Party fails to deliver the Claim Notice to the Indemnifying Party within 30 days after the Indemnified Party receives notice of such Third Party Claim, the Indemnifying Party will not be obligated to indemnify the Indemnified Party with respect to such Third Party Claim if and only to the extent that the Indemnifying Party’s ability to defend the Third Party Claim has been irreparably prejudiced by such failure. The Indemnifying Party will notify the Indemnified Party within 10 days after receipt of the Claim Notice (the “Notice Period”) whether the Indemnifying Party intends, at the sole cost and expense of the Indemnifying Party, to defend the Indemnified Party against the Third Party Claim. The assumption by the Indemnifying Party of the defense of the Third Party Claim constitutes an admission by the Indemnifying Party that the claim is one for which the Indemnifying Party is ultimately liable under this Article.

(ii) If the Indemnifying Party notifies the Indemnified Party within the Notice Period that the Indemnifying Party intends to defend the Indemnified Party against the Third Party Claim, then the Indemnifying Party will have the right to

defend, at its sole cost and expense, the Third Party Claim by all appropriate proceedings, which proceedings will be diligently prosecuted by the Indemnifying Party to a final conclusion or settled at the discretion of the Indemnifying Party (with the consent of the Indemnified Party). The Indemnifying Party will have full control of such defense and proceedings; provided that the Indemnified Party may file during the Notice Period, at the sole cost and expense of the Indemnified Party, any motion, answer or other pleading that the Indemnified Party may deem necessary or appropriate to protect its interests and not irrevocably prejudicial to the Indemnifying Party (it being understood and agreed that, except as provided in Section 9.05(a)(iii), if an Indemnified Party takes any such action that is irrevocably prejudicial and conclusively causes a final adjudication that is materially adverse to the Indemnifying Party, the Indemnifying Party will be relieved of its obligations hereunder with respect to that portion of the Third Party Claim prejudiced by the Indemnified Party’s action); and provided further that, if requested by the Indemnifying Party, the Indemnified Party shall cooperate, at the sole cost and expense of the Indemnifying Party, with the Indemnifying Party and its counsel in contesting any Third Party Claim that the Indemnifying Party elects to contest or, if appropriate in the judgment of the Indemnified Party and related to the Third Party Claim, in making any counterclaim or cross-claim against any Person (other than the Indemnified Party). The Indemnified Party may participate in, but not control, any defense or settlement of any Third Party Claim assumed by the Indemnifying Party pursuant to this Section 9.05(a)(ii) and, except as provided in the preceding sentence, the Indemnified Party will bear its own costs and expenses with respect to such participation. Notwithstanding the foregoing, the Indemnifying Party may not assume the defense of the Third Party Claim on behalf of the Indemnified Party if (1) the Persons against whom the claim is made, or any impleaded Persons, include both the Indemnifying Party and any Indemnified Party, and (2) representation of both such Persons by the same counsel would be inappropriate due to actual or potential differing interests between them, in which case any Indemnified Party shall have the right to defend the Third Party Claim on its own behalf and to employ counsel at the expense of the Indemnifying Party.

(iii) If the Indemnifying Party fails to notify the Indemnified Party within the Notice Period that the Indemnifying Party intends to defend the Indemnified Party against the Third Party Claim, or if the Indemnifying Party gives such notice but fails to diligently prosecute or settle the Third Party Claim, or if the Indemnifying Party fails to give any notice whatsoever within the Notice Period, then the Indemnified Party will have the right (but not the obligation) to defend, at the sole cost and expense of the Indemnifying Party, the Third Party Claim by all appropriate proceedings, which proceedings will be diligently prosecuted by the Indemnified Party to a final conclusion or settled at the discretion of the Indemnified Party. The Indemnified Party will have full control of such defense and proceedings, including any compromise or settlement thereof; provided that, if requested by the Indemnified Party, the Indemnifying Party shall cooperate, at the sole cost and expense of the Indemnifying Party, with the Indemnified Party and its counsel in contesting the Third Party Claim which the

Indemnified Party is contesting, or, if appropriate and related to the Third Party Claim in question, in making any counterclaim or cross claim against any Person (other than the Indemnifying Party).

(iv) Notwithstanding the foregoing provisions of Section 9.05(a)(iii), if the Indemnifying Party notifies the Indemnified Party within the Notice Period that the Indemnifying Party disputes its obligation to indemnify the Indemnified Party against the Third Party Claim, and if such dispute is resolved pursuant to Section 9.05(c) in favor of the Indemnifying Party, the Indemnifying Party will not be required to bear the costs and expenses of the Indemnified Party’s defense pursuant to Section 9.05(a)(iii) or of the Indemnifying Party’s participation therein at the Indemnified Party’s request, and the Indemnified Party will reimburse the Indemnifying Party in full for all such costs and expenses. The Indemnifying Party may participate in, but not control, any defense or settlement controlled by the Indemnified Party pursuant to Section 9.05(a)(iii), but the Indemnifying Party will bear its own costs and expenses with respect thereto if such participation is not at the request of the Indemnified Party.

(b) In the event any Indemnified Party should have a claim against any Indemnifying Party that is not a Third Party Claim, the Indemnified Party shall deliver an Indemnity Notice with reasonable promptness to the Indemnifying Party specifying the nature of and specific basis for the claim and, to the extent then feasible, the amount or the estimated amount of the claim. The failure by any Indemnified Party to give timely notice referred to in the preceding sentence shall not impair such Person’s rights hereunder except to the extent that an Indemnifying Party demonstrates that it has been irreparably prejudiced thereby. If the Indemnifying Party does not notify the Indemnified Party within ten days following its receipt of the Indemnity Notice that the Indemnifying Party disputes its obligation to indemnify the Indemnified Party hereunder, the claim will be conclusively deemed a liability of the Indemnifying Party hereunder.

(c) If the Indemnifying Party timely disputes its liability with respect to a claim described in a Claim Notice or an Indemnity Notice, the Indemnifying Party and the Indemnified Party shall proceed promptly and in good faith to negotiate a resolution of such dispute within 60 days following receipt of the Claim Notice or Indemnity Notice.

(d) The Indemnifying Party shall pay the amount of any liability to the Indemnified Party within 30 days following its receipt of a Claim Notice or an Indemnity Notice, or on such later date (i) in the case of a Third Party Claim, as the Indemnified Party suffers Losses in respect of the Third Party Claim, or (ii) in the case of an Indemnity Notice in which the amount of the claim is estimated, promptly after any Losses in respect of such claim are actually incurred by the Indemnified Party. In the event the Indemnified Party is not paid in full for its claim in a timely manner after the Indemnifying Party’s obligation to indemnify and the amount thereof has been determined, the amount due shall bear interest from the date that the Indemnifying Party received the Claim Notice or the Indemnity Notice until paid at the interest rate provided in Section 10.15, and in addition to any other rights it may have against the Indemnifying

Party, the Indemnified Party shall have the right to set-off the unpaid amount of such claim against any amounts owed by it to the Indemnifying Party.

(e) Any estimated amount of a claim submitted in a Claim Notice or an Indemnity Notice shall not be conclusive of the final amount of such claim, and the giving of a Claim Notice when an Indemnity Notice is properly due, or the giving of an Indemnity Notice when a Claim Notice is properly due, shall not impair such Indemnified Party’s rights hereunder except to the extent that an Indemnifying Party demonstrates that it has been irreparably prejudiced thereby. Notice of any claim comprised in part of Third Party Claims and claims that are not Third Party Claims may be given pursuant to either Section 9.05(a) or 9.05(b).

9.06. Contribution. In recognition of the fact that Buyer and San Antonio Partners are Affiliates, the obligations of Seller and San Antonio Partners to indemnify any Indemnified Persons pursuant to Section 9.01 is a several obligation and not a joint, or a joint and several, obligation. As a result, Buyer’s Indemnified Persons may seek indemnification against Seller without also being required to join San Antonio Partners in the claim, but Buyer’s Indemnified Persons may not seek indemnification solely against San Antonio Partners. Furthermore, the extent to which Seller or San Antonio Partners shall be liable to any Indemnified Party for Losses in respect of any particular claim shall be determined by multiplying (i) the total Losses suffered by the Indemnified Party in respect of which the claim was made times (ii) the percentage interest of Seller or San Antonio Partners, as the case may be, in the Partnership in respect of which the claim arose. If Seller is held by a court of competent jurisdiction to be liable to any Indemnified Party for Losses that exceed Seller’s percentage share of such Losses, as determined by the immediately preceding sentence, Buyer and San Antonio Partners shall jointly and severally be obligated to contribute to the amount paid or payable by Seller as a result of such claim in such proportion as is appropriate to reflect the relative percentage interest of Seller and of San Antonio Partners in connection with the Partnership in respect of which the claim arose. Notwithstanding anything in this Agreement to the contrary, Seller shall not have any obligation to make any contribution or to indemnify or hold harmless San Antonio Partners for any Loss incurred or suffered by Buyer, except in connection with a Third Party Claim in which Seller was a defendant.

9.07. Survival of Representations; Indemnity Periods.

(a) Notwithstanding the right of Buyer to investigate the Centers or any right of any Party to investigate the accuracy of the representations and warranties of another Party in this Agreement, or any actual investigation by or knowledge of a Party, Seller has, on the one hand, and Buyer and Vanguard have, on the other hand, the right to rely fully upon the representations, warranties, covenants and agreements of the other contained in this Agreement, and except as expressly provide otherwise in Section 9.02, Seller’s obligations in this Agreement to indemnify Buyer’s Indemnified Persons for breaches of any representation or warranty of Seller pursuant to this Article 9 will not be affected by any investigation by or on behalf of Buyer or by Buyer’s knowledge that any such representation is or might be untrue. The representations and warranties contained in this Agreement made by Seller and Buyer, respectively, will survive the Closing (X) indefinitely with respect to matters covered by Sections 3.02 (a), 3.04, 4.02(a) and 4.03

and (Y) until two years after the Closing Date in the case of all other representations and warranties, except that

(i) any representation or warranty that would otherwise terminate in accordance with clause (b) above shall survive if a Claim Notice or an Indemnity Notice shall have been given on or prior to such termination date, until the related claim for indemnification has been satisfied or otherwise resolved as provided in this Article and

(ii) in the event of intentional misrepresentation or fraud in the making of any representation or warranty, all representations and warranties, that are the subject of the intentional misrepresentation or fraud shall survive until 60 days after the expiration of all applicable statutes of limitations (including all periods of extension, whether automatic or permissive) with respect to matters covered thereby.

(b) All covenants and agreements to be performed after the Closing Date will survive the Closing for the term specified therein, or, if no term is specified, indefinitely. Rights to indemnification under this Article will survive until any claims brought hereunder shall have been satisfied or otherwise resolved as provided herein.

10.

GENERAL

10.01. Schedules.

(a) The Schedules and all exhibits and documents referred to in or attached to this Agreement are integral parts of this Agreement as if fully set forth herein and all statements appearing therein shall be deemed to be representations. Nothing in the Schedules shall be deemed adequate to disclose an exception to a representation or warranty made herein unless the Schedule identifies the exception with reasonable particularity and, without limiting the generality of the foregoing, the mere listing of a document as an exception to any representation or warranty shall not be deemed to disclose the contents of such document as an exception to any representation or warranty.

(b) At or prior to Closing, Seller shall modify or amend the Schedules or deliver to the Buyer new Schedules as necessary to make each of the representations and warranties of Seller contained in Article 3 true and correct in all material respects on and as of the Closing Date, provided that without Buyer’s written consent, (i) Seller may not modify or amend any Schedule to disclose any event or circumstance that occurred prior to the Effective Date, (ii) Seller may not modify or amend any Schedule to disclose any event or circumstance attributable to the default or breach by Seller of any covenant or agreement contained in this Agreement, (iii) Seller may not modify or amend any Schedule relating to the representations and warranties in Section 3.05, 3.07 or 3.08, and (iv) no such modification or amendment may add any Encumbrances or any material liabilities or obligations of the Partnerships.

10.02. Tax and Government Payment Program Effect. None of the Parties (nor such Parties’ counsel or accountants) has made or is making in this Agreement any representation to

any other Party (or such Party’s counsel or accountants) concerning any of the Tax or Government Payment Program effects or consequences on the other Party of the transactions provided for in this Agreement. Each Party represents that it has obtained, or may obtain, independent Tax and Government Payment Program advice with respect thereto and upon which it, if so obtained, has solely relied.

10.03. Reproduction of Documents. This Agreement and all documents relating hereto, including consents, waivers and modifications which may hereafter be executed, the Closing Documents, financial statements, certificates and other information previously or hereafter furnished to any Party, may be reproduced by any Party by any photographic, microfilm, electronic or similar process and the Parties may destroy any original documents so reproduced. The Parties stipulate that any such reproduction shall be admissible in evidence as the original itself in any judicial, arbitral or administrative proceeding (whether or not the original is in existence and whether or not such reproduction was made in the ordinary course of business) and that any enlargement, facsimile or further reproduction of such reproduction shall likewise be admissible in evidence.

10.04. Missing Consents to Assignment. Anything contained herein to the contrary notwithstanding, this Agreement shall not constitute an agreement to assign any Contract, claim or other right if the transfer of the Partnership Interests would constitute an assignment thereof and without the consent of another Person such assignment would (i) constitute a breach thereof or in any material way affect the rights of the Partnership or Buyer thereunder, (ii) be ineffective or render the Contract void or voidable, or (iii) materially affect the Partnership’s or Buyer’s rights thereunder so that Buyer would not in fact receive all such rights. In any such event, Seller shall cooperate in any reasonable arrangement designed to provide for Buyer the benefits under any such Contract, claim or right, including enforcement of any and all rights of Seller against the other Person arising out of the breach or cancellation by such other Person or otherwise. After Closing, the Parties shall continue to use commercially reasonable efforts to obtain the consent of the assignment of such Contract, claim or right.

10.05. Time of Essence. Time is of the essence in the performance of this Agreement, provided that, if the day on or by which a notice must or may be given, or the performance of any Party’s obligation is due, is a Saturday, Sunday or holiday for banks in San Antonio, Texas, then the day on or by which such notice must or may be given, or that such performance is due, shall automatically be extended to the first business day thereafter. This Section may be waived only in a writing expressly referring hereto.

10.06. Consents, Approvals and Discretion. Except as herein expressly provided to the contrary, whenever this Agreement requires or permits any consent or approval to be given by any Party or provides that any Party must or may exercise discretion, such consent or approval shall not be unreasonably withheld, conditioned or delayed and such discretion shall be reasonably exercised.

10.07. Choice of Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Texas without regard to such State’s conflicts of laws rules.

10.08. Benefit; Assignment. This Agreement shall inure to the benefit of and be binding upon the Parties and their respective legal representatives, successors and assigns. No Party may assign its rights under this Agreement without the prior written consent of the other Parties, provided that Buyer may assign this Agreement, in whole or in part, to any Affiliate of Buyer, and to any other Person who takes title to all or any portion of the Partnership Interests in connection with Buyer’s financing (including a sale/leaseback) of the transactions described herein.

10.09. Third Party Beneficiary. The terms and provisions of this Agreement (including provisions regarding employee and employee benefit matters) are intended solely for the benefit of the Parties, Buyer’s Indemnified Persons, Seller’s Indemnified Persons, and their respective successors and permitted assigns, and are not intended to confer third-party beneficiary rights upon any other Person. Any reference in this Agreement to one or more Employee Benefit Plans of Buyer includes provisions, if any, in such plans permitting their termination or amendment and any covenant in this Agreement to provide any Employee Benefit Plan shall not be deemed or construed to limit Buyer’s right to terminate or amend such plan of Buyer in accordance with its terms.

10.10. Waiver of Breach, Right or Remedy. The waiver by any Party of any breach or violation by another Party of any provision of this Agreement or of any right or remedy permitted the waiving Party in this Agreement (i) shall not waive or be construed to waive any subsequent breach or violation of the same provision (ii) shall not waive or be construed to waive a breach or violation of any other provision, and (iii) must be express and must be in writing and may not be presumed or inferred from any Party’s conduct. Except as expressly provided otherwise in this Agreement, no remedy conferred by this Agreement is intended to be exclusive of any other remedy, and each and every remedy shall be in addition to every other remedy granted in this Agreement or now or hereafter existing at law or in equity, by statute or otherwise. The election of any one or more remedies by a Party shall not constitute a waiver of the right to pursue other available remedies. In addition to any other rights and remedies any Party may have at law or in equity for breach of this Agreement, each Party shall be entitled to seek an injunction to enforce the provisions of this Agreement.

10.11. Notices. Any notice, demand or communication required, permitted or desired to be given hereunder shall be deemed effectively given if given in writing (i) on the date tendered by personal delivery, (ii) on the date received by facsimile or other electronic means, (iii) on the date tendered for delivery by nationally recognized overnight courier, or (iv) on the date tendered for delivery by United States mail, with postage prepaid thereon, certified or registered mail, return receipt requested, in any event addressed as follows:

or to such other address or number, and to the attention of such other Person, as any Party may designate at any time in writing in conformity with this Section.

10.12. Misdirected Payments; Offset. Each Party shall remit to the proper Party with reasonable promptness any monies received by such Party that should have been received by the other Party pursuant to the terms of this Agreement, including any monies received by Buyer, San Antonio Partners or the Partnerships with respect to the Accounts Receivables. If Buyer reasonably determines after Closing that funds previously paid or credited to Seller in respect of services rendered prior to the Closing Date have resulted in an overpayment or must be repaid, Seller shall be responsible for the repayment of said monies (and the defense of such actions). If any Party suffers any deduction to or offset or withhold against amounts due to such Party as a result of amounts owed by another Party, the other Party shall promptly pay to such Party the amounts so billed or offset upon demand. Any amounts due Buyer by Seller or its Affiliate, or due Seller by Buyer or its Affiliate, may be offset against monies or other funds held by the Party entitled to payment.

10.13. Severability. If any provision of this Agreement is held or determined to be illegal, invalid or unenforceable under any present or future law, and if the rights or obligations of any Party under this Agreement will not be materially and adversely affected thereby: (a) such provision will be fully severable; (b) this Agreement will be construed and enforced as if such illegal, invalid or unenforceable provision had never comprised a part of this Agreement; (c) the remaining provisions of this Agreement will remain in full force and effect and will not be affected by the illegal, invalid or unenforceable provision or by its severance from this Agreement; and (d) in lieu of such illegal, invalid or unenforceable provision, there will be added automatically as a part of this Agreement a legal, valid and enforceable provision as similar in terms to such illegal, invalid or unenforceable provision as may be possible.

10.14. Entire Agreement; Amendment. This Agreement supersedes all previous contracts, agreements and understandings and constitutes the entire agreement of whatsoever kind or nature existing between or among the Parties representing the within subject matter and no Party shall be entitled to benefits other than those specified herein. As between or among the Parties, any oral or written representation, agreement or statement not expressly incorporated herein, whether given prior to or on the Effective Date, shall be of no force and effect unless and until made in writing and signed by the Parties on or after the Effective Date. The representations and warranties set forth in this Agreement shall survive the Closing and remain in full force and effect as provided in Article 9, and shall survive the execution and delivery of all other agreements, instruments or other documents described, referenced or contemplated herein and shall not be merged herewith or therewith. Each representation, warranty and covenant contained in this Agreement has independent significance and if any Party has breached any representation, warranty or covenant contained herein in any respect, the fact that there exists another representation, warranty or covenant relating to the same subject matter (regardless of the relative level of specificity) that such Party has not breached shall not detract

from or mitigate the fact that the Party is in breach of the first representation, warranty or covenant. This Agreement may be executed in two or more counterparts, each and all of which shall be deemed an original and all of which together shall constitute but one and the same instrument. This Agreement may not be amended except in a written instrument executed the Parties.

10.15. Interest. Unless otherwise provided herein to the contrary, any monies required to be paid by any Party to another Party pursuant to this Agreement shall be due two business days after demand therefor and if not paid when due shall accrue interest from and after the due date to and including the date full payment is made at an annual rate equal to the average prime rate of Citibank, N.A., during such period plus three percent per annum.

10.16. Drafting. No provision of this Agreement shall be interpreted for or against any Person on the basis that such Person was the draftsman of such provision, and no presumption or burden of proof shall arise favoring or disfavoring any Person by virtue of the authorship of any provision of this Agreement.

10.17. Confidentiality; Public Announcements.

(a) Except as required by Legal Requirements, Seller and Radiologix, on the one hand, and Buyer and Vanguard, on the other hand, shall keep this Agreement and its contents confidential and not disclose the same to any Person (except the Parties’ attorneys, accountants or other professional advisors and except to the applicable Governmental Authorities in connection with any required notification or application for approval or a license or exemption therefrom) without the prior written consent of the other Party.

(b) At all times before the Closing, Seller, on the one hand, and Buyer, on the other hand, will consult with the other before issuing or making any reports, statements or releases to the public with respect to this Agreement or the transactions contemplated hereby and will use good faith efforts to obtain the other Party’s approval of the text of any public report, statement or release to be made on behalf of such Party. If either Party is unable to obtain the approval of its public report, statement or release from the other Party and such report, statement or release is, in the opinion of legal counsel to such Party, necessary to discharge such Party’s disclosure obligations under law, then such Party may make or issue the legally required report, statement or release and promptly furnish the other Party a copy thereof. Nothing herein shall prohibit any Party from responding to questions presented by the press or media without first obtaining prior written consent of the other Party.
