ARTICLE III



Services to be Provided by PIP



Section 3.1
General. PIP shall provide or arrange for the services set forth in this Article III. PIP is authorized to perform its services hereunder as is necessary or appropriate for the efficient operation of the PIP Facilities, including, without
limitation, performance of the business office functions at locations other than the PIP Facilities. Except to the extent necessary to comply with applicable laws, regulations or professional ethical standards, Group will not act in a manner which
would prevent PIP from performing its duties hereunder and will provide such information and assistance to PIP as is reasonably required by PIP to perform its services hereunder. PIP shall cause its employees to comply with all applicable federal,
state and local laws, rules and regulations in PIPs provision of services hereunder.



Section 3.2 General Administrative Services.



(a) Scope of Services. PIP shall be responsible for providing certain non-medical business services relating to the operation of the PIP Facilities, subject to matters reserved for Group as herein contemplated,
and PIP shall have all necessary authority and hereby agrees to perform such services. Subject to Section 4.3 below, PIP agrees that Group, Physician Employees and Physician Extender Employees, and only Group, Physician Employees and Physician
Extender Employees, will perform the professional supervision and interpretation services at the PIP Facilities. PIP shall have no authority, directly or indirectly, to perform, and shall not perform, any professional medical function; provided,
however, that PIP may at any time perform technical-only imaging services for any person or entity at the PIP Facilities, so long as such person or entity is not affiliated with PIP or Parent (the PIP Technical Imaging Services) and the
PIP Facilities continue to have sufficient availability for non-PIP Technical Imaging Services; provided, however, that Group shall not be responsible for the performance or supervision of the PIP Technical Imaging Services and Group shall not be
liable, contractually or otherwise, with respect to the provision of the PIP Technical Imaging Services. PIP acknowledges that the primary intent of the PIP Facilities is to provide professional supervision and interpretation services, and technical
services, on a global fee basis, and PIP Technical Services are not intended to displace global fee work generated at the PIP Facilities.



(b) Billing and Collection.



(i) To the extent permitted by law and at PIPs sole discretion, PIP shall directly bill and collect all patients, insurance companies, Managed Care
Payors and other third-party payors for all professional interpretation and technical fee charges incurred in connection with services rendered at the PIP Facilities (the Facility Charges), but excluding the billing and collection of
professional services rendered to the patients of Hill, which will be Groups sole responsibility. PIP will deposit all collections from Facility Charges directly into the PIP Account.



(ii) To the extent required by law or if PIP does not directly bill and
collect pursuant to Section 3.2(b)(i) above, PIP shall bill and collect, in the name of and on behalf of Group, any patients, insurance companies, Managed Care Payors, or other third-party payors for any Facility Charges, except for professional
services rendered to the Hill patients, which will be Groups sole responsibility. PIP will deposit all collections from Facility Charges directly into the Deposit Account. Group hereby appoints PIP for the term of this Agreement to be its true
and lawful attorney-in-fact, for the following purposes:



(A)
to bill patients, insurance companies, Managed Care Payors and other third-party payors for all Facility Charges in Groups name and on its behalf;



-4-



---

(B) to receive payments for Facility Charges on behalf of Group from patients, insurance companies,
Managed Care Payors and other third-party payors, and to deposit such collections into the Deposit Account; and



(C) upon the prior consent of Group, which consent shall not be unreasonably withheld or delayed, to initiate the institution of legal proceedings in the
name of Group or a Physician Employee to collect any accounts and monies owed to Group or the Physician Employee, to enforce the rights of Group or the Physician Employee, as the case may be, as creditor under any contract or in connection with the
Facility Charges, and to contest adjustments and denials by governmental agencies (or their fiscal intermediaries) as third-party payors.



(iii) Group hereby appoints PIP as its true and lawful attorney-in-fact to deposit into the Deposit Account all amounts collected by PIP pursuant to this
Agreement. Group covenants, and shall cause all Physician Employees and Physician Extender Employees to forward any payments received with respect to any revenues generated from professional supervision and interpretation services and related
technical imaging services rendered by Group or any of its Physician Employees and Physician Extender Employees at the PIP Facilities, except for professional services rendered to the Hill patients, which will be Groups sole responsibility, to
PIP for deposit into the Deposit Account. PIP shall have the right to withdraw funds from the Deposit Account and all owners of the Deposit Account shall execute a revocable standing transfer order (the Transfer Order) under which the
bank maintaining the Deposit Account shall, on a daily basis, transfer the entire balance of the Deposit Account into the PIP Account; provided, however, that Group, to the extent PIP is not satisfying its payment obligations to Group pursuant to
Sections 6.1 and 6.2 below, shall have the right to prevent the transfer from the Deposit Account to the PIP Account of any unpaid Contract Fee owing to Group. In connection with this Agreement, Group hereby assigns and transfers to PIP all rights
and interest Group may have to the funds transferred from the Deposit Account into the PIP Account. Group and PIP hereby agree to execute from time to time such documents and instructions as shall be required by the bank maintaining the Deposit
Account to effectuate the foregoing provisions and to extend or amend such documents and instructions. Any action by Group or its Physician Employees that materially interferes with the operation of this Section 3.2, including, without limitation,
any failure to deposit or to have PIP deposit any revenues into the Deposit Account, any withdrawal of any funds from the Deposit Account not authorized by the express terms of this Agreement, or any revocation of or attempt to revoke the Transfer
Order (otherwise than upon expiration or termination of this Agreement), will constitute a breach of this Agreement and will entitle PIP, in addition to any other remedies it may have at law or in equity, to seek a court ordered assignment of the
rights provided to PIP pursuant to Section 3.2(b)(ii) above; provided, however, that the foregoing is not intended to prevent Group, to the extent PIP is not satisfying its payment obligations to Group pursuant to Sections 6.1 and 6.2 below, from
preventing the transfer from the Deposit Account to the PIP Account of any unpaid Contract Fee owing to Group.



(iv) Group shall execute such documents in form and substance as are reasonably necessary to permit PIP to exercise the rights and powers granted to PIP
pursuant to this Section 3.2(b). Group shall cooperate with, and at the request of PIP shall provide reasonable assistance to, PIP with the functions set forth herein. In the performance of the services described in this Section 3.2(b), PIP shall
use commercially reasonable best efforts to collect such Facility Charges, and shall comply with all applicable Managed Care Contracts and all applicable laws, rules and regulations.



(c) Accounting. PIP shall administer and maintain the operation of an appropriate accounting system with respect to
its collection and payment obligations under this Agreement, including the maintenance, custody and supervision of business records, ledgers and reports. Group and its authorized representatives shall have the right to review all such financial
records and bank records maintained by PIP relating to the PIP Account or the Deposit Account and uses contemplated by Section 3.2(d) below. Such information shall be provided by PIP to Group in any media reasonably requested.



(d) Cash Management. PIP shall manage and transfer the cash and cash
equivalents transferred into the PIP Account to any other account of PIP, and to use such cash for purposes as PIP deems appropriate, subject to and consistent with the terms and provisions of this Agreement, including, without limitation, the right
of Group, to the extent PIP is not satisfying its payment obligations to Group pursuant to Sections 6.1 and 6.2 below, to prevent the transfer from the Deposit Account to the PIP Account of any unpaid Contract Fee owing to Group.

charges and accounts receivable statistics, and monthly reconciliation reports on cash management relating to the revenues generated from the professional supervision and interpretation services rendered at the PIP Facilities, which shall be
delivered to Group as soon as practicable, but no later than thirty (30) days after the end of each calendar month. Group may elect to have an audit conducted with respect to such financial statements by an accounting firm selected by Group, in its
sole discretion, in which case the cost of such audit shall be Groups sole responsibility, unless such audit discloses a material discrepancy, equal to or greater than ten percent (10%) of the amount to which Group would otherwise have been
entitled to pursuant to Section 6.1 below, in which case the audit costs shall be borne solely by PIP. Any undisputed additional amounts determined to be owed by one party to the other party as a result of any audit shall be paid to the appropriate
party within thirty (30) days of its determination.



(f)
Records and Files.



(i) PIPs Business and
Financial Records. At all times during and after the term of this Agreement, including any extensions or renewals hereof, all business records, including but not limited to, business agreements, books of account, personnel records, general
administrative records and all information generated under or contained in the management information system pertaining to PIPs obligations hereunder, and other business information of PIP of any kind or nature, except for patient medical
records and Groups Records, shall be and remain the sole property of PIP; provided, however, that during and after termination of this Agreement, Group shall be entitled to reasonable access to such records and information relating to a
particular PIP Facility, including the right to obtain copies thereof in any media reasonably requested by Group, for any purpose related to patient care or the defense of any claim relating to patient care, and PIP agrees to safeguard such records

direct electronic access to PIPs radiology information system and during regular business hours with regard to other information, and upon reasonable prior written notice, to patient billing and demographic data for purposes of billing,
collection and charge verification, including direct electronic access to PIPs radiology information system. Group hereby agrees to be responsible for any additional costs and expenses related to such direct electronic access, including
programming, telecommunications, hardware or software costs required to provide such direct electronic access, so long as PIP delivers to Group advance notice of such costs and expenses. PIP and Group hereby agree to preserve the confidentiality of
such patient medical records and to use the information in such records only for the limited purposes necessary to perform its responsibilities hereunder.



(ii) Groups Business and Financial Records. At all times during and after the term of this Agreement, the patient medical records and charts
and any other information relating exclusively to the business and activities of Group in connection with this Agreement (hereinafter referred to as the Groups Records) shall be and remain the sole property of Group; provided,
however, that Groups Records shall be the sole property of PIP following such time as PIP obtains IDTF (as defined in Section 3.5 below) status from Medicare or any other similar designation permitted under California law such that a
particular PIP Facility would be permitted to directly bill and collect professional supervision and interpretation services and/or technical imaging services from Managed Care Payors. Notwithstanding the foregoing, PIP acknowledges and agrees that

generally being charged in the same or similar market areas, and (b) for all re-billings and recovery items on prepaid Managed Care Contracts which are authorized and permitted by such contracts. Notwithstanding anything in this Section 4.3 or this
Agreement to the contrary, PIP shall have the right to obtain additional or substitute professional supervision and interpretation services coverage for the PIP Facilities from any physician or other provider to the extent PIP deems, in its
reasonable discretion, that the professional interpretation and supervision service coverage by Group through the Physician Employees and the Physician Extender Employees is inadequate, so long as PIP first provides to Group a written notice
specifying in sufficient detail why the professional interpretation and supervision services are materially inadequate, and Group is unable to correct the problems, to the reasonable satisfaction of PIP, within thirty (30) days of receipt by Group
of such written notice.



Section 4.4 Groups Internal
Matters. Group shall be responsible for matters involving its corporate governance, employees and similar internal matters, including, without limitation, preparation and contents of such reports to regulatory authorities governing Group that
Group is required by law to provide, distribution of income, disposition of Groups property and stock, hiring and firing of its employees, licensing and implementing all compliance plans and procedures as described in Section 4.5 below. The
costs incurred in connection with the foregoing matters shall be borne solely by Group. Group shall be solely responsible for all business and administrative functions related to Group, except as specifically set forth in this Agreement.



Section 4.5 Compliance with Laws. Group shall, and shall use its
commercially reasonable best efforts to cause the Physician Employees, Physician Extender Employees and other employees of Group to, comply with all applicable federal, state and local laws, rules, regulations and restrictions in the conduct of the
professional supervision and interpretation services provided under this Agreement. Without limiting the generality of the foregoing, Group shall comply and shall cause each Physician Employee, Physician Extender Employee and other employee of

Group to comply, with all laws applicable to the operation of the PIP Facilities in the generation,
transportation, treatment, storage, disposal or other handling of radioactive, medical, biological or hazardous materials or waste, and Group shall not, and shall use its commercially reasonable best efforts to prohibit any Physician Employee,
Physician Extender Employee and any other employee of Group from:



(a) entering into any contract, lease, agreement or arrangement, including, without limitation, any joint venture or consulting agreement, to provide services, lease space, lease equipment or engage in any other venture or activity with any
physician, hospital, pharmacy, home health agency or other person or entity which is in a position to make or influence referrals to, or otherwise generate business for, the PIP Facilities;



(b) knowingly and willfully making or causing to be made a false statement or
representation of a material fact in any application for any benefit or payment from a Managed Care Payor or any other third party payor;



(c) knowingly and willfully making or causing to be made a false statement or representation of a material fact for use in determining rights to any
benefit or payment from a Managed Care Payor or any other third party payor;



(d) failing to disclose knowledge by a claimant of the occurrence of any event affecting the initial or continued right to any benefit or payment on its own behalf or on behalf of another, with intent to fraudulently
secure such benefit or payment;



(e) knowingly and willfully
paying, soliciting or receiving any remuneration (including any kickback, bribe, or rebate), directly or indirectly, overtly or covertly, in cash or in kind or offering to pay or receive such remuneration (i) in return for referring an individual to
a person for the furnishing or arranging for the furnishing of any item or service for which payment may be made in whole or in part by Medicare or Medi-Cal, or (ii) in return for purchasing, leasing, or ordering, or arranging for or recommending
purchasing, leasing, or ordering any good, facility, service, or item for which payment may be made in whole or in part by Medicare or Medi-Cal;



(f) referring a patient for health services or products to, or providing health services to a patient upon a referral from, an entity or person with which
the physician or an immediate family member has a financial relationship, other than as permitted by exceptions set forth in federal or state anti-referral laws or regulations; and



(g) undertaking any action that is not in accord with the regulatory compliance plans, policies and manuals developed and
implemented by PIP or Group, and used in conjunction with the PIP Facilities.



Section 4.6 Ancillary Services. Group shall not acquire, establish or commence the operation of any satellite location, medical office, imaging center, health maintenance organization, preferred provider
organization, exclusive provider organization or similar entity or organization established or operated by Group after the date hereof without the prior written consent of PIP. Group and the Physician Employees and the Physician Extender Employees
shall be permitted to use the PIP Facilities only in connection with the provision of professional supervision and interpretation services for patients being treated at the PIP Facilities and for no other purposes whatsoever, except that such
parties may continue to provide professional services to Hill, professional services to family members of the Physician Employees and the Physician Extender Employees, outside reading services similar in type and scope to those reading services
currently being provided by Group as specified in Exhibit 2 attached hereto, and incorporated herein by this reference, and de minimis activities, provided that such activities do not disrupt or interfere in any material respect with the PIP
Facilities or their employees, or otherwise cause PIP to incur any additional costs or expenses.



Section 4.7 PIP Facilities and Personal Property. Group shall use its commercially reasonable best efforts to prevent damage, excessive wear and
tear, and malfunction or other breakdown of the PIP Facilities and Personal Property or any part thereof by the Physician Employees and Physician Extender Employees or other employees of Group. Group shall promptly inform PIP both orally and in
writing of any and all necessary replacements, repairs or maintenance to any of the PIP Facilities or Personal Property and any failures of equipment of which it becomes aware. Group shall use commercially reasonable best efforts to comply with all
covenants and provisions set forth in any leases or subleases for the PIP Facilities entered into or assumed by PIP, and PIP agrees to make available to Group copies of all such leases or subleases to Group. Group shall, and shall ensure that its
Physician Employees and



-10-



---

Physician Extender Employees, reasonably cooperate with PIP in promoting the business interests of the PIP Facilities,
including, without limitation, not interfering with PIPs existing or future contractual relationships with any Managed Care Payor relating to the professional or technical services rendered at the PIP Facilities, exclusive of the Permitted
Activities.



Section 4.8 AII Obligations. AII shall, and
shall ensure that its shareholders, directors, officers and the Physician Employees, reasonably cooperate with PIP in promoting the best business interests of the PIP Facilities, including, without limitation, not interfering with PIPs
existing or future contractual relationships with any Managed Care Payor relating to the professional or technical services rendered at the PIP Facilities, exclusive of the Permitted Activities. AII shall be required to provide professional services
to patients covered under Groups or PIPs current and future Hill managed care contract in the hospitals and entities currently acting as Hill contractors to Group or PIP (Alta Bates Summit Medical Center, St. Lukes Hospital, St.
Rose Hospital, San Ramon Regional Medical Center and Medical Center Magnetic Imaging). In this regard, AII shall also be responsible for positively promoting the Hill relationship to these hospital contractors, and assisting PIP and Group to
minimize the costs and utilization associated with such hospital contractor relationships.



Section 4.9 Events Excusing Performance. In the event of strikes, lock-outs, calamities, acts of God, unavailability of supplies or other events over which Group has no control, Group shall not be liable to
PIP, Parent or their Affiliates for failure to perform any of its obligations required hereunder as may be materially restricted by any such event and PIP shall not have the right to terminate this Agreement pursuant to Section 8.4(a) below, for so
long as such events continue and for a reasonable period of time thereafter; provided, however, that if such events continue and Group is not able to perform any material portion of its obligations required hereunder for a period of one hundred
twenty (120) consecutive days or more, either Group or PIP may terminate this Agreement by written notice to the other parties.



Section 4.10 Use of Name. Group hereby grants to PIP and Parent the non-exclusive right to use all or any portion of Groups name in
connection with the PIP Facilities.

discharge of its obligations under this Agreement and not to use, except in the pursuit of the business of the PIP Facilities, Group Confidential and Proprietary Information, without the prior written consent of



-12-



---

Group or AII; unless (A) such information becomes known or available to the public generally through no wrongful act of
PIP, Parent or their Affiliates or their employees, or (B) disclosure is required by law or the rule, regulation or order of any governmental authority under color of law; provided, however, that prior to disclosing any of Group Confidential and
Proprietary Information pursuant to this clause (B), PIP, Parent or their Affiliates shall, if possible, give prior written notice thereof to Group or AII and provide Group or AII with the opportunity to contest such disclosure. PIP, Parent and
their Affiliates shall take all necessary and proper precautions against disclosure of any of Group Confidential and Proprietary Information to unauthorized persons by any of its officers, directors, employees or agents. All officers, directors,
employees, and agents of PIP, Parent and their Affiliates who will have access to all or any part of Group Confidential and Proprietary Information will be required to execute an agreement upon request, valid under the law of the jurisdiction in
which such agreement is executed, and in a form acceptable to PIP, Parent or their Affiliates and their counsel, committing themselves to maintain Group Confidential and Proprietary Information in strict confidence and not to disclose it to any
unauthorized person or entity. Upon the expiration or the earlier termination of this Agreement for any reason, PIP, Parent and their Affiliates and their employees shall cease all use of any of Groups Confidential and Proprietary Information
and shall execute such documents as may be reasonably necessary to evidence their abandonment of any claim thereto.



(iii) Return of Materials. Upon the expiration or the earlier termination of this Agreement for any reason whatsoever, or at any time upon the
request of Group or AII, PIP, Parent and their Affiliates will promptly deliver or cause to be delivered to Group all documents, data and other information in their possession that contain any of Group Confidential and Proprietary Information. PIP,

act of Group, AII or any of their employees; or (C) is disclosed pursuant to a statute, regulation or the order of a court of competent jurisdiction, provided that Group or AII provides prior notice to PIP, Parent or its Affiliates. PIP and Parent
acknowledge and agree that AIIs proposed development of a billing and collection program shall not be deemed to be a violation of this Section 5.1(d)(i) solely because of Groups use of employees or contractors previously involved with
PIP, so long as AII maintains all confidential and proprietary information protected by third party contracts regarding such information.



(ii) Covenant Not-to-Divulge PIP Confidential and Proprietary Information. Group and AII hereby acknowledge and agree that PIP, Parent or their

regulation or order of any governmental authority under color of law; provided, however, that prior to disclosing any PIP Confidential and



-13-

Proprietary Information pursuant to this clause (B), Group or AII, as the case may be, shall, if possible, give prior
written notice thereof to PIP, Parent and their Affiliates and provide such parties with the opportunity to contest such disclosure. Group and AII shall take all necessary and proper precautions against disclosure of any PIP Confidential and
Proprietary Information to unauthorized persons by any of its officers, directors, employees or agents. All officers, directors, employees, and agents of Group or AII who will have access to all or any part of PIP Confidential and Proprietary
Information will be required to execute an agreement upon request, valid under the law of the jurisdiction in which such agreement is executed, and in a form acceptable to PIP, Parent and their Affiliates and its counsel, committing themselves to
maintain PIP Confidential and Proprietary Information in strict confidence and not to disclose it to any unauthorized person or entity. Upon termination of this Agreement for any reason, Group, AII and their employees shall cease all use of any of
PIP Confidential and Proprietary Information and shall execute such documents as may be reasonably necessary to evidence their abandonment of any claim thereto.



(iii) Return of Materials. Upon the expiration or the earlier termination of this Agreement for any reason whatsoever, or at any time upon the
request of PIP, Parent or their Affiliates, Group and AII will promptly deliver or cause to be delivered to PIP, Parent and their Affiliates all documents, data and other information in their possession that contains any PIP Confidential and
Proprietary Information regarding PIP, Parent and their Affiliates. Neither Group nor AII shall take or retain any documents or other information, or any reproduction or excerpt thereof, containing any PIP Confidential and Proprietary Information,

(e) Third Party Beneficiaries. The members of the Northern California RGX Group not party to this Agreement are hereby specifically made third
party beneficiaries of this Section 5.1, with the power to enforce the provisions hereof.



Section 5.2 Restrictive Covenants. Group and AII shall obtain written agreements with each Physician Employee or Group Physician Stockholder, which written agreements shall contain certain restrictive covenants
thereof (similar to the covenants applicable to Group and AII, as contained in Section 5.1 above) pertaining to covenants not to compete and/or solicit with and not to divulge PIP Confidential and Proprietary Information (the Restrictive
Covenants). Each Physician Employee or Group Physician Stockholder shall agree, during the term of his or her employment or contractor agreement with Group or AII, as the case may be, and for a period of twenty-four (24) months after the
expiration or the earlier termination of such agreement (but in no event longer than twenty-four (24) months following the expiration or the earlier termination of this Agreement): (a) not to establish, operate or provide professional radiology
services at any office, practice, hospital or health care facility providing services substantially similar to those provided at the PIP Facilities pursuant to this Agreement within fifteen (15) miles of any PIP Facility, and (b) to be bound by
non-solicitation, noncompetition and nondisclosure of confidential/proprietary information and engagement of PIP covenants similar to those applicable to Group and AII, as contained in Section 5.1 above. Neither Group nor AII shall materially amend,
alter or otherwise change any term or provision of any agreement or contract relating to the foregoing covenants in this Section 5.2 without the prior written consent of PIP. Notwithstanding the foregoing, any such amendment, alteration or change
shall not be inconsistent with the terms or provisions contained in this Agreement. Following the expiration or the earlier termination of this Agreement, neither Group nor AII shall amend, alter or otherwise change any term or provision of the
Restrictive Covenants, unless such provisions are no longer in force and effect pursuant to the terms of the applicable agreement or contract at the time of the expiration or the earlier termination of this Agreement.



Section 5.3 Enforcement of Restrictive Covenants and Other Provisions.
Group and AII may enforce the Restrictive Covenants to the extent permitted under applicable law. In the event that, after a request by PIP, Group or AII, as the case may be, does not pursue any remedy that may be available to it by reason of a
breach or default of the Restrictive Covenants, upon the request of PIP, Group or AII, as the case may be, shall assign to PIP such causes of action and/or other rights it has related to such breach or default and shall cooperate with and provide
reasonable assistance to PIP with respect thereto; in which case, all costs and expenses incurred in connection therewith shall be borne by PIP.



Section 5.4 Remedies. PIP and Group acknowledge and agree that a remedy at law for any breach or attempted breach of the provisions of this Article
V shall be inadequate, and therefore, either party shall be entitled to specific performance and injunctive or other equitable relief in the event of any such breach or attempted breach, in addition to any other rights or remedies available to
either party at law or in equity. Each party hereto waives any



-14-



---

requirement for the securing or posting of any bond in connection with the obtaining of any such injunctive or other
equitable relief. If any provision of the Restrictive Covenants or this Article V relating to the restrictive period, scope of activity restricted and/or the territory described therein shall be declared by a court of competent jurisdiction to
exceed the maximum time period, scope of activity restricted or geographical area such court deems reasonable and enforceable under applicable law, the time period, scope of activity restricted and/or area of restriction held reasonable and
enforceable by the court shall thereafter be the restrictive period, scope of activity restricted and/or the geographical area applicable to such provision of the Restrictive Covenants or this Article V. The invalidity or non-enforceability of any
provision of the Restrictive Covenants or this Article V in any respect shall not affect the validity or enforceability of the remainder of the Restrictive Covenants or this Article V or of any other provisions of this Agreement.



Section 5.5 Survival of Certain Covenants. If this Agreement is
terminated pursuant to Section 8.4(a), the provisions of Section 5.1, Section 5.2 and Section 5.3 shall survive such termination for a period of two (2) years following termination if the actions or events giving rise to a breach of the Restrictive
Covenants or other provisions occurred prior to such termination. However, regardless of the reason for termination, or upon expiration of this Agreement, the provisions of Section 5.1(b), (c), (d) and (e) shall survive such termination or
expiration for a period of two (2) years following such termination or expiration.



ARTICLE VI



Financial
and Security Arrangements



Section 6.1 Contract Fee.
Group and PIP agree that the compensation set forth in this Article VI is being paid to PIP in consideration of the professional supervision and interpretation services to be provided by Group through the Physician Employees, and that such fees have
been negotiated at arms length and are fair, reasonable and consistent with fair market value. Group shall be paid a contract fee in an amount equal to XX percent (X%) of actual global collections received by PIP during the preceding
calendar month relating to the professional supervision and interpretation services rendered after December 31, 2001 by Group through the Physician Employees or the Physician Employee Extenders at the PIP Facilities (but specifically excluding any
professional services rendered to the patients of Hill, which professional service fee charges shall be the sole responsibility of Group, and any technical fee revenues received for PIP Technical Imaging Services), whether received from patients,
Managed Care Payors or other third party payors, and less refunds, chargebacks and credits incurred in such calendar month (collectively, the Contract Fee). Compensation of Group for professional interpretation and supervision services
rendered through and including December 31, 2001 shall be as set forth in the Release. Payment of the Contract Fee by PIP into the Group Account is not intended to and shall not be interpreted or implied as permitting PIP to share in Groups
fees for medical services, but is acknowledged as the negotiated fair market value compensation to Group considering the scope of the professional supervision and interpretation services rendered at the PIP Facilities. PIP and Group may consider
revising the Contract Fee following June 1, 2004 (the third (3rd) anniversary of the Hill contract renewal) in the event that the Hill contract reverts from a professional services only, fee-for-service basis to a global payment methodology. If the
parties are unable to agree upon new terms, then upon the termination of the Hill contract, either PIP or Group may terminate this Agreement upon at least one hundred eighty (180) days prior written notice to the other parties.



Section 6.2 Payments. The amounts to be paid to Group under this
Article VI shall be calculated by PIP on the cash basis of accounting and shall be payable monthly. Payments due for any Contract Fee shall be made by PIP into the Group Account each calendar month as provided herein and shall be paid on the
fifteenth (15th) day following the end of such month (or the first preceding day that is a business day if the fifteenth (15th) day is not a business day) (a Payment Date). Such amounts shall be paid based upon available information for
such month, and any adjustments to the Contract Fee shall be made on the next Payment Date. PIP shall not withhold any Contract Fee during any dispute between Group and PIP, so long as Group continues to perform the professional supervision and
interpretation services in accordance with this Agreement.



Section 6.3 Security Agreement. In order to enforce its rights granted hereunder and subject to applicable law, Group shall execute a Security Agreement in substantially the form attached hereto as Exhibit 4 (the
Security Agreement), and incorporated herein by this reference, which Security Agreement grants a security interest in all of Groups accounts receivable (as more fully described in the Security Agreement) to PIP; provided, however,
that such security interest shall not include any funds that are transferred from the Deposit Account into



-15-



---

the Group Account. In addition, Group shall cooperate with PIP and execute all necessary documents in connection with the
pledge of such accounts receivable to PIP or at PIPs option, to its or Parents lenders.



ARTICLE VII



Insurance and Indemnification



Section 7.1
Insurance to be Maintained by Group. During the term of this Agreement, Group shall maintain comprehensive professional medical/malpractice liability insurance with such carrier as may be mutually agreeable by PIP and Group with the limits
set forth in Section 4.1 above, unless higher limits shall be required under Groups contracts with hospitals or other third parties. Such insurance shall be on a per claim and per physician basis and a separate limit for Group to the extent
available and permitted by law with such deductible as is mutually agreeable by PIP and Group. All comprehensive professional medical/malpractice liability insurance premiums and deductibles shall be borne solely by Group. All costs, expenses and
liabilities incurred by Group in excess of the limits of such policies identified in the preceding sentence shall also be borne solely by Group.



Section 7.2 Insurance to be Maintained by PIP. During the term of this Agreement, PIP will provide and maintain comprehensive professional
medical/malpractice liability insurance for all applicable employees of PIP, and comprehensive general liability and property insurance covering the PIP Facilities, personal property and operations with such limits and coverages as a reasonable
business person under similar circumstances would maintain. All comprehensive professional medical/malpractice liability insurance and comprehensive general liability and property insurance premiums and deductibles shall be borne solely by PIP. All
costs, expenses and liabilities incurred by PIP in excess of the limits of such policies identified in the preceding sentence shall also be borne solely by PIP.



Section 7.3 Continuing Liability Insurance Coverage. Group shall obtain, or require each of the Physician Employees and Physician Extender
Employees to obtain, continuing liability insurance coverage under either a tail policy or a prior acts policy, with the same limits and deductibles as the insurance coverage provided pursuant to Section 7.1 above upon the
termination of such physicians (or other providers) relationship with Group for any reason, unless such physician (or other provider) was covered with an occurrence-based policy while employed or retained by Group or AII. In the event
that Group or any Physician Employee or Physician Extender Employee fails to obtain such continuing liability insurance coverage, PIP may do so. The cost of such continuing liability insurance coverage shall be borne solely by Group or AII.



Section 7.4 Additional Insureds. Group and PIP agree to
use their commercially reasonable best efforts to have each other named as an additional insured on the others respective professional liability insurance programs. The additional cost, if any, associated therewith shall be borne by the
policyholder of each such insurance program.



Section 7.5
Indemnification.



(a) By Group. Group and AII,
jointly and severally, shall indemnify, defend and hold PIP, Parent, their Affiliates and their respective officers, directors, shareholders, employees, agents, attorneys and consultants (other than such persons who are also officers, directors,
shareholders, employees, agents or consultants of Group or AII) harmless, from and against any and all liabilities, losses, damages, claims, causes of action and expenses (including reasonable attorneys fees), not covered by insurance
(including self-insured insurance and reserves), whenever arising or incurred, that are caused or asserted to have been caused, directly or indirectly, by or as a result of the performance of medical services by Group, AII or their employees and
contractors during the term of this Agreement (excluding the provision of PIP Technical Imaging Services) or the performance of any intentional acts, negligent acts or omissions by Group and/or its shareholders, employees and/or subcontractors
(other than PIP, Parent, their Affiliates or their employees, officers, directors, agents, attorneys and consultants) during the term of this Agreement. Provided, however, that in the event an indemnification obligation under the preceding sentence
arises as of the result of any act or omission of a person who is an officer, shareholder or other equity holder, director, employee, agent, attorney or consultant of PIP, Parent or any of its Affiliates, such person shall not be entitled to
indemnification in connection therewith and any other adjustment as is equitable shall be made to Groups indemnification obligation arising thereby.

(b) By PIP. PIP and Parent, jointly and severally, shall indemnify, defend and hold Group and its
officers, shareholders, directors, employees, agents, attorneys and consultants, harmless from and against any and all liabilities, losses, damages, claims, causes of action and expenses (including reasonable attorneys fees), not covered by
insurance (including self-insured insurance and reserves), whenever arising or incurred, that are caused or asserted to have been caused, directly or indirectly, by or as a result of the performance of any intentional acts, negligent acts or

Parent, or (E) is notified in writing of any adverse action by any state or federal department or agency that has the
effect of either excluding that individual from participating in or from receiving reimbursement under any program funded by the federal government or by any state government (subitems (B), (C) and (D) immediately above do not create due process
employment issues for Group, since Groups obligation to cure the material breach is merely to remove such individual from rendering professional supervision and interpretation services at the PIP Facilities as described immediately below).
Notwithstanding anything to the contrary contained in this Section 8.4, upon written notification to Group of a violation of Section 8.4(a)(v) above, Group may cure such Material Group Default by permanently removing such Physician Employee from
rendering professional supervision and interpretation services at the PIP Facilities.

Termination Notice) and expiration of applicable cure periods; or



(b) Upon the expiration of this Agreement pursuant to Sections 8.1 or 8.2 above.



Section 8.6 Effect Upon Termination. Upon the Termination Date, except as provided below, this Agreement shall terminate and shall be of no further
force and effect and all further obligations of PIP, Parent and/or their Affiliates and Group and AII under this Agreement shall terminate without further liability of the PIP, Parent and/or their Affiliates to Group or AII, or Group and AII to PIP,
Parent and/or their Affiliates, except with respect to the obligations set forth below. The foregoing to the contrary notwithstanding:



(a) Each party hereto shall provide the other party with reasonable access to books and records owned by it to permit such requesting party to satisfy
reporting and contractual obligations which may be required of it.



(b) Any other amounts due and owing but unpaid to either Group or PIP as of the Termination Date shall be paid, as due, by the appropriate party.



(c) Any and all covenants and obligations of either party hereto which by their terms or by reasonable implication are to be performed, in whole or in
part, after the termination of this Agreement, shall survive such termination for the period specified in this Agreement, including, without limitation, the obligations of the parties pursuant to the following Sections: 5.1(b), 5.1(c), 5.1(d),
5.1(e), 5.2, 5.3, 7.5 and the applicable provisions of Article VIII.



ARTICLE IX



General Provisions



Section 9.1 Assignment. PIP shall have the right to
assign its rights hereunder to Parent or any direct or indirect wholly-owned subsidiary of PIP or Parent or to an Affiliate without the consent of Group; provided, however, that no assignment hereunder shall relieve PIP or Parent of their
obligations hereunder without the consent of Group.



Section
9.2 Amendments. This Agreement shall not be modified or amended except by a written document executed by all parties to this Agreement, and such written modification(s) or amendment(s) shall be attached hereto.



Section 9.3 Waiver of Provisions. Any waiver of any terms and
conditions hereof must be in writing, and signed by the parties hereto. The waiver of any of the terms and conditions of this Agreement shall not be construed as a waiver of any other terms and conditions hereof.



-19-



---

Section 9.4 Additional Documents. Each of the parties hereto agrees to execute any document or
documents that may be reasonably requested from time to time by the other party to implement or complete such partys obligations pursuant to this Agreement.



Section 9.5 Attorneys Fees. If legal action is commenced by either party to enforce or defend its rights under
this Agreement, the prevailing party in such action shall be entitled to recover all reasonable attorneys fees, costs and expenses including, but not limited to, attorneys fees, costs and expenses for trial, appellate proceedings and
negotiations, in addition to any other relief granted.



Section
9.6 Contract Modifications for Prospective Legal Events. In the event any state or federal laws or regulations, now existing or enacted or promulgated after the date hereof, are interpreted by judicial decision, a regulatory agency or
independent legal counsel in such a manner as to indicate that this Agreement or any provision hereof may be in violation of such laws or regulations, Group and PIP shall amend this Agreement as necessary to preserve the underlying economic and
financial arrangements between Group and PIP and without substantial economic detriment to either party. To the extent any act or service required of PIP in this Agreement should be construed or deemed, by any governmental authority, agency or court
to constitute the practice of medicine, the performance of said act or service by PIP shall be deemed waived and forever unenforceable and the provisions of this Section 9.6 shall be applicable. Neither party shall claim or assert illegality as a
defense to the enforcement of this Agreement or any provision hereof.



Section 9.7 Parties In Interest; No Third Party Beneficiaries. Except as otherwise provided herein, the terms and conditions of this Agreement shall inure to the benefit of and be binding upon the respective heirs, legal
representatives, successors and permitted assigns of the parties hereto. Except as provided in Section 5.1(e) above, neither this Agreement nor any other agreement contemplated hereby shall be deemed to confer upon any person not a party hereto or
thereto any rights or remedies hereunder or thereunder.



Section 9.8 Entire Agreement. This Agreement and the agreements contemplated hereby constitute the entire agreement of the parties regarding the subject matter hereof, and supersede all prior agreements and understandings, both
written and oral, among the parties, or any of them, with respect to the subject matter hereof.



Section 9.9 Severability. If any provision of this Agreement is held to be illegal, invalid or unenforceable under present or future laws effective
during the term hereof, such provision shall be fully severable and this Agreement shall be construed and enforced as if such illegal, invalid or unenforceable provision never comprised a part hereof; and the remaining provisions hereof shall remain
in full force and effect and shall not be affected by the illegal, invalid or unenforceable provision or by its severance herefrom. Furthermore, in lieu of such illegal, invalid or unenforceable provision, there shall be added automatically as part
of this Agreement a provision as similar in its terms to such illegal, invalid or unenforceable provision as may be possible and be legal, valid and enforceable.



Section 9.10 Governing Law; Venue. This Agreement and the rights and obligations of the parties hereto shall be
governed by and construed and enforced in accordance with the substantive laws (but not the rule governing conflicts of laws) of the State of California. The exclusive venue of any dispute arising out of or relating to the subject matter of this
Agreement shall be in a court of competent jurisdiction located in San Francisco County, Contra Costa County or Alameda County, California, and the parties hereto hereby consent to the personal jurisdiction of such courts.



Section 9.11 No Waiver; Remedies Cumulative. No party hereto shall by
any act (except by written instrument pursuant to Section 9.3 above), delay, indulgence, omission or otherwise be deemed to have waived any right or remedy hereunder or to have acquiesced in any default in or breach of any of the terms and
conditions hereof. No failure to exercise, nor any delay in exercising, on the part of any party hereto, any right, power or privilege hereunder shall operate as a waiver thereof. No single or partial exercise of any right, power or privilege
hereunder shall preclude any other or further exercise thereof or the exercise of any other right, power or privilege. No remedy set forth in this Agreement or otherwise conferred upon or reserved to any party shall be considered exclusive of any
other remedy available to any party, but the same shall be distinct, separate and cumulative and may be exercised from time to time as often as occasion may arise or as may be deemed expedient.

convenience of reference only and shall not limit or otherwise affect any of the terms or provisions hereof.
