               ADMINISTRATIVE SERVICES TO BE PROVIDED BY RESPONSE

      5.1.  Performance of Management Functions.  Response shall provide or
arrange for the services set forth in this Article 5, the cost of all of which
shall be paid by Response and included in Clinic Expenses.  Response is hereby
expressly authorized to perform its services hereunder in whatever manner it
deems reasonably appropriate to meet the day-to-day requirements of Clinic
operations in accordance with the general standards approved by the Oversight
Committee, including, without limitation, performance of some of the business
office functions at locations other than a Clinic.  Oncology will not act in a
manner which would prevent Response from efficiently managing the day-to-day
operations of each Clinic in a business-like manner.

      5.2.  Financial Planning and Goals.  Response shall prepare annual
capital and operating budgets reflecting in reasonable detail anticipated
revenue and expenses, sources and uses of capital for growth in Oncology's
practice and medical services rendered at each Clinic.  Response shall
determine the amount and form of capital to be invested annually in each Clinic
and shall specify the targeted profit margin for each Clinic which shall be
reflected in the overall budget.  Response realizes that a Clinic may realize
opportunities to provide new services and utilize new technologies that will
require capital expenditures and anticipates that





                                      -10-
   11

such opportunities may include ambulatory surgery centers, renovations to
Clinic facilities, the addition of satellite locations and new and replacement
equipment as may be economically justified.  Such budgets shall be presented to
the Oversight Committee at least sixty (60) days prior to the end of the
preceding calendar year.  The budget shall be agreed upon by the Oversight
Committee at least thirty (30) days prior to the end of such preceding Calendar
year as provided in Section 4.2(b), and, once approved in such manner, shall be
binding upon Response and Oncology unless modified or revised in like manner by
the Oversight Committee.

      5.3.  Financial Statements.  Response shall prepare annual financial
statements on a cash basis for the separate operations of each Clinic and shall
prepare an annual pro-forma, accrual basis combined income statement for all
Clinics for purposes of determining the Annual Surplus.  If Oncology desires an
audit of any financial statement, Oncology may obtain such an audit at its own
expense.  Response shall prepare monthly unaudited financial statements
containing a combined balance sheet and statements of operations for the
Clinics, which shall be delivered to Oncology within thirty (30) days after the
close of each calendar month.  Notwithstanding the foregoing, Response shall be
under no obligation to keep multiple sets of books for cash basis and accrual
basis methods of accounting, but shall be entitled to keep one set of books
maintained on an accrual basis method of accounting, which shall be converted
by workpaper-only entries to the cash basis method of accounting for purposes
of preparing the cash basis financial statements described above.

      5.4.  Inventory and Supplies.  Response shall order and purchase
reasonable and requested medical and office inventory and supplies required by
Oncology to provide quality services in the day-to-day operations of its
medical practice.

      5.5.  Management Services and Administration.

           (a)  Oncology hereby appoints Response as its sole and exclusive
      manager and administrator of all day-to-day business functions connected
      with its group medical practice.  Oncology agrees that the purpose and
      intent of this Service Agreement is to relieve Oncology, the Physician
      Stockholders and Physician Employees to the maximum extent possible of
      the administrative, accounting, payroll, accounts payable, personnel and
      business aspects of its practice, with Response assuming responsibility
      for and being given all necessary authority to perform these functions.
      Response agrees that Oncology, and only Oncology, will perform the
      medical functions of its practice.  Response will have no authority,
      directly or indirectly, to perform, and will not perform, any medical
      function.  Response may, however, advise Oncology as to the relationship
      between its performance of medical functions and the overall
      administrative and business functioning of its practice.  To the extent
      that they assist Oncology in performing medical functions, all clinical
      personnel performing patient care services obtained and provided by
      Response shall be subject to the professional direction and supervision
      of Oncology and, in the performance of such medical functions, shall not
      be subject to any direction or control by, or liability to, Response,
      except as may be specifically authorized by Oncology.  Oncology hereby
      indemnifies and holds Response, its officers, directors, shareholders,
      agents and affiliates, their successors and assigns ("Indemnified
      Persons") harmless, and shall reimburse the Indemnified Persons for, from
      and against each claim, loss, liability, cost and expense (including,
      without limitation, interest, penalties, costs of preparation and
      investigation, and the reasonable fees and disbursement expenses of
      attorneys and other professional advisors) directly or indirectly
      relating to, resulting from or arising out of any medical function
      performed, or which should have been performed, under the supervision of
      Oncology or Physician Employees.

           (b)  Response shall, on behalf of Oncology, bill patients and Third
      Party Payors, and shall collect the professional fees for medical
      services rendered by Oncology in each Clinic, for services performed
      outside a Clinic for Oncology's hospitalized patients, and for all other
      professional and Clinic services.  Response's billing and collection
      practice shall be consistent with those of comparable, nationally
      recognized, well managed group medical practices.  Oncology hereby
      appoints





                                      -11-
   12

      Response for the term hereof to be its true and lawful attorney-in-fact,
      for the following purposes:  (i) to bill patients in Oncology's name and
      on its behalf;  (ii) to collect Accounts Receivable resulting from such
      billing in Oncology's name and on its behalf; (iii)  to receive payments
      from insurance companies, prepayments from health care plans, and
      payments from all other Third Party Payors;  (iv) to take possession of
      and endorse in the name of Oncology (and/or in the name of an individual
      physician, such payment intended for purpose of payment of a physician's
      bill) any notes, checks, money orders, insurance payments and other
      instruments received in payment of Accounts Receivable; and  (v) with the
      advance consent of the Oversight Committee, to initiate legal proceedings
      in the name of Oncology or any Physician Employee to collect any accounts
      and monies owed to Oncology, Clinic or any Physician Employee, to enforce
      the rights of Oncology or any Physician Employee as a creditor under any
      contract or in connection with the rendering of any service, and to
      contest adjustments and denials by any Governmental Authority (or its
      fiscal intermediaries) as Third Party Payors.  All adjustments made for
      uncollectible accounts, professional courtesies and other activities that
      do not generate a collectible fee shall be done in a reasonable and
      consistent manner.

           (c)  Response shall design, supervise and maintain custody of all
      files and records relating to the operation of each Clinic, including but
      not limited to accounting, billing, patient medical records, and
      collection records.  Patient medical records shall at all times be and
      remain the property of Oncology and shall be located at Clinic facilities
      so that they are readily accessible for patient care.  The Physician
      Employees shall have the obligation to oversee the preparation and
      maintenance of patient medical records, and to provide such medical
      information as shall be necessary and appropriate to the clinical
      function of such records, and to maintain such records so as to ensure
      the availability of Third-party Payor reimbursement for services
      rendered.  The management of all files and records shall comply with
      applicable state and federal statutes.  Response shall use its best
      efforts to preserve the confidentiality of patient medical records and
      use information contained in such records only for the limited purpose
      necessary to perform the services set forth herein; provided, however, in
      no event shall a breach of said confidentiality be deemed a default under
      this Agreement.

           (d)  Response shall supply to Oncology necessary clerical,
      accounting, payroll, bookkeeping and computer services, laundry, linen,
      uniforms, printing, stationary, advertising, postage and duplication
      services, medical transcribing services and any other ordinary, necessary
      or appropriate item or service for the operation of a Clinic, the cost of
      all of which shall be Clinic Expense.

           (e)  Subject to the provisions of Section 4.2(d), Response shall
      design and implement adequate and appropriate marketing and public
      relations programs on behalf of Oncology, with appropriate emphasis on
      public awareness of the availability of services at Oncology's Clinics.
      Any marketing or public relations program shall be conducted in
      compliance with applicable laws and regulations governing advertising by
      medical professionals.

           (f)  Response shall provide the data necessary for Oncology to
      prepare its annual income tax returns and financial statements, and shall
      provide payroll and related services for Physician Employees.  Response
      shall have no responsibility for the filing of such tax returns, the
      payment of such income taxes or the cost of preparation of income tax
      returns or financial statements on behalf of Oncology or any physician
      employed thereby.

           (g)  Response shall assist Oncology in recruiting additional
      physicians, carrying out such administrative functions as may be
      appropriate such as advertising for and identifying potential candidates,
      checking credentials, and arranging interviews; provided, however,
      Oncology shall interview and make the ultimate decision as to the
      suitability of any physician to become associated with a Clinic.  All
      physicians recruited by Response and accepted by Oncology shall be the
      sole employees of Oncology, to the extent such physicians are hired as
      employees.  Subject to the provisions of





                                      -12-
   13

      Section 6.4, any expenses incurred in the recruitment of physicians,
      including, but not limited to, employment agency fees, relocation and
      interviewing expenses shall be Clinic Expenses.

           (h)  Subject to the provisions of Section 4.2(g), Response shall
      negotiate and administer all managed care contracts on behalf of
      Oncology.

           (i)  Subject to the provisions of Sections 5.3 and 5.5(f), Response
      shall arrange for legal and accounting services related to Clinic
      operations incurred traditionally in the ordinary course of business,
      including the cost of enforcing any physician contract containing
      restrictive covenants, provided such services shall be approved in
      advance by the Executive Director.

           (j)  Response shall provide for the proper cleanliness of the
      physical premises occupied and/or utilized by Oncology, and maintenance
      and cleanliness of the equipment, furniture and furnishings located upon
      such premises.

      5.6.  Executive Director.  Subject to the provisions of Section 4.2(k),
Response shall recruit, hire and appoint an Executive Director to manage and
administer all of the day-to-day business functions of each Clinic (it being
understood and agreed that, if reasonable, a single Executive Director may have
responsibility for multiple Clinics).  Subject to Oversight Committee approval,
Response shall determine the salary, bonuses (if any) and fringe benefits of
each Executive Director, which salary, bonuses (which may be payable in
Response common stock or by issuance of options on Response common stock) and
benefits shall, to the extent the same are current expenses under GAAP, be
Clinic Expenses. At the direction, supervision and control of Response, the
Executive Director, subject to the terms of this Agreement, shall implement the
policies established by the Oversight Committee and shall generally perform the
duties and have the responsibilities of an administrator.  The Executive
Director shall be responsible for organizing the agenda for the meetings of the
Oversight Committee referred to in Article 4.

      5.7.  Personnel.  Response shall provide Physician Extender Personnel and
other non-physician professional support (other than Technical Employees and
other persons who are required to be Physician Employees) and administrative
personnel, clerical, secretarial, bookkeeping and collection personnel
reasonably necessary for the conduct of operations at each clinic.  Response
shall determine and cause to be paid the salaries and fringe benefits of all
such personnel, which shall be Clinic Expenses.  Such personnel shall be under
the direction, supervision and control of Response, with those personnel
performing billable patient care services remaining employees of and being
subject to the professional supervision of Oncology.  If Oncology is
dissatisfied with the services of any person, Oncology shall consult with
Response.  Response shall in good faith determine whether the performance of
that employee could be brought to acceptable levels through counsel and
assistance, or whether such employee's employment should be terminated.  All of
Response's obligations regarding staff shall be governed by the overriding
principle and goal of providing high quality medical care.  Employee
assignments shall be made to assure consistent and continued rendering of high
quality medical support services and to ensure prompt availability and
accessibility of individual medical support personnel to physicians in order to
develop constant, familiar and routine working relationships between individual
physicians and individual members of the medical support personnel.  Response
shall maintain established working relationships wherever possible and Response
shall make every effort consistent with sound business practices to honor the
specific requests of Oncology with regard to the assignment of its employees.
In addition to the foregoing, Response shall advance to Oncology from time to
time the amount of any operating deficiency with respect to any new physician
who is an employee but not a shareholder of Oncology ("Junior Physician").
Operating deficiency with respect to a Junior Physician is hereby defined as
the excess of the amount payable to such Junior Physician pursuant to any
salary guarantee over the amount of salary payable to such Junior Physician
under Oncology's normal and customary compensation system, as the same may be
modified from time to time by Oncology.  Upon the earliest to occur of (i) the
Junior Physician becoming a shareholder of Oncology, or (ii) the Junior
Physician recognizing billings in excess of





                                      -13-
   14

his cost (as determined by the Oversight Committee, a "Surplus"), Oncology
shall begin repaying the amounts theretofore advanced in respect of such Junior
Physician.  Such advanced amounts shall be repaid in full within thirty (30)
days after the occurrence of the event enumerated (i) above, and, in the event
item (ii) above shall occur, shall be repaid as Surplus is recognized, in
quarterly amounts equal to such surplus for each quarter, within sixty (60)
days after the end of each such quarter; provided, however, that all such
advances shall be payable in full by Oncology no later than the third
anniversary of the employment date of such Junior Physician.

      5.8.  Events Excusing Performance.  Response shall not be liable to
Oncology for failure to perform any of the services required herein in the
event of strikes, lock-outs, calamities, acts of God, unavailability of
supplies or other events over which Response has no control for so long as such
events continue, and for a reasonable period of time thereafter.

      5.9.  Compliance with Applicable Laws.  Response shall comply with all
Applicable Law, in the conduct of its obligations under this Agreement.

      5.10.  Quality Assurance.  Response shall assist Oncology in fulfilling
its obligations to its patients to maintain a high quality of medical and
professional services.

      5.11.  Oncology Operating Account.  Oncology agrees to establish and
maintain a bank account, which shall be referred to as the Oncology Operating
Account, for the purpose of (a) depositing Practice Revenue and advances from
the Receivables Line (defined below) pursuant to Section 5.12 and (b) paying
(i) the Clinic Expense Portion of Service Fees owed pursuant to Section 8.1 of
this Agreement, (ii) expenses which are solely the obligation of Oncology,
including, without limitation, Physician Employee Compensation, (iii) the Fixed
Portion of Service Fees owed pursuant to Section 8.1 of this Agreement, and
(iv) distributions to Oncology, and the distributions shall be made in that
order of payment.  Oncology hereby designates, constitutes and appoints the
Chief Financial Officer and Treasurer of Response as a signatory on the
Oncology Operating Account, with full power and authority to sign checks and
cause drafts and other debits to be made on the Oncology Operating Account in
the name of Oncology and to otherwise manage the cash resources and flow of
Oncology.  After the payment of all Service Fees and expenses hereinabove
described, Oncology may withdraw amounts for distributions to Physician
Stockholders; provided, however, that Oncology agrees to maintain an adequate
balance in the Oncology Operating Account to pay the Clinic Expense Portion of
Service Fees as projected in the budget formulated pursuant to this Agreement.

      5.12.  Credit Line.  Response shall from time to time during the term of
this Agreement advance to Oncology, in readily available United State funds, by
wire transfer, intrabank transfer or other electronic means, to be deposited
into the Oncology Operating Account, an amount (the "Receivables Line") equal
to 100% of Accounts Receivable, net of any Bad Debt Allowance and all Fee
Adjustments with respect thereto.  Amounts advanced by Response under the
Receivables Line will bear interest at a rate equal to the prime or base
lending rate quoted from time to time by First Tennessee Bank National
Association, plus one-half percent (.5%).  Amounts advanced by Response
pursuant to this Section 5.12 shall be payable by Oncology upon demand, and if
no demand be made, upon termination of this Agreement.  Response shall have the
authority from time to time pursuant to Section 5.11 above to make principal
payments on the Receivables Line.  Interest on the outstanding Receivables Line
will be computed on a daily basis based on the total unpaid and outstanding
advances on the Receivables Line.  Interest shall be payable to Response no
later than the fifth day of each month, in arrears.  Advances on the
Receivables Line will be secured by a security interest in and to Accounts
Receivable granted pursuant to Section 15.8 below.

           So long as an Oncology Event of Default has not occurred, advances
on the Receivables Line shall be made by Response as required to provide funds
in the Oncology Operating Account sufficient to pay, in the following order (i)
the Clinic Expense Portion of the Base Service Fee, (ii) Physician Employee





                                      -14-
   15

Compensation, (iii) other practice expenses which are not Clinic Expenses up to
an amount equal to the Physician Retainage, less the Base Draw, and (iv) the
Base Draw.

      5.13.  Ancillary Services.  Response shall operate such ancillary
services as approved by the Oversight Committee.

provider guidelines must be filed or registered with any Third Party Payor,
Oncology agrees to cooperate with Response in making such filings or
registrations.  it is agreed and acknowledged that all such peer review
guidelines shall be established and monitored by medical personnel on the staff
of Oncology and other practices that are part of the peer review process, and
shall not be promulgated, established or enforced independently by Response.
To the extent possible, all information obtained through the peer review
process shall remain confidential and the parties shall take all steps
reasonably necessary to assure that all privileges and immunities provided by
Applicable Law remain intact.

                                   ARTICLE 7.
           EMPLOYMENT AGREEMENTS, RESTRICTIVE COVENANTS AND REMEDIES

           The parties recognize that the services to be provided by Response
shall be feasible only if Oncology operates an active medical practice to which
the physicians associated with Oncology devote their full time and attention.
To that end:

      7.1. Employment Agreements with Physicians.  As a condition to Response's
continuing obligations hereunder, Oncology and each physician now or
hereinafter employed thereby shall execute and deliver to each other an
employment contract substantially in the form set forth as Exhibit 2.1(aa)
hereto ("Employment Agreement").

      7.2.  Restrictive Covenants by Physicians.  Oncology shall obtain in each
Employment Agreement and use its best efforts to enforce (subject to Response's
obligations under Section 5.5 of this Agreement) formal agreements from each
physician pursuant to which the physician agrees not to establish, operate or
provide physician services at any medical office, clinic or outpatient and/or
ambulatory treatment or diagnostic facility providing services substantially
similar to those provided by Oncology pursuant to this Agreement within Dade
and Monroe Counties in Florida (the "Practice Territory") during the term of
the Employment Agreement and for a period of five (5) years after any
termination of employment with Oncology.  Notwithstanding the foregoing, any
such restrictive covenant shall not restrict such physician from (i) delivering
physician services that are unrelated to the fields of hematology or oncology,
including the practice of internal medicine, (ii) teaching hematology and/or
oncology or (iii) assuming directorships of hospices following termination of
any such employment relationship with Oncology.

   17

      7.3.  Restrictive Covenants of Response.  During the term of this
Agreement, neither Response nor any Affiliate, officer, director or employee of
Response or any Affiliate shall, without the consent of Oncology, purchase or
otherwise acquire any oncology or hematology practice within the Practice
Territory or establish, operate or enter into a service agreement with, or
provide service similar to those provided under this Agreement to, any medical
group or physician engaged in the practice of oncology or hematology within the
Practice Territory.

      7.4.  Enforcement.  Response and Oncology acknowledge and agree that
since a remedy at law for any breach or attempted breach of the provisions of
this Article 7 shall be inadequate, either party shall be entitled to specific
performance and injunctive or other equitable relief in case of any such breach
or attempted breach, in addition to whatever other remedies may exist by law.
All parties hereto also waive any 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 Article 7 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 territory applicable to the restrictive covenant
provisions in this Article 7.  The invalidity or non-enforceability of this
Article 7 in any respect shall not affect the validity or enforceability of the
remainder of this Article 7 or of any other provisions of this Agreement.


                                   ARTICLE 8.
                             FINANCIAL ARRANGEMENTS

      8.1.  Service Fees.  In consideration for its services hereunder,
Response shall receive the Base Service Fee and Performance Fee, computed
pursuant to Schedule A hereto, as compensation for its services hereunder,
payable by means of the Base Draw procedure set forth in Section 8.2 below.

      8.2.  Base Draw.  The Clinic Expense Portion of the Base Service Fee
shall be payable by Oncology to Response out of the Oncology Operating Account
as Clinic Expenses are incurred by Response, subject to ordinary, reasonable
and customary payment terms on invoices for goods and services.  The Base Draw
shall be payable by Oncology to Response out of the Oncology Operating Account
on a monthly basis for the purpose of paying the Fixed Portion of the Base
Service Fee and providing Response with an advance on its annual Performance
Fee (if any).  The Base Fee and the Performance Fee will be computed as of the
end of each calendar year based on amounts recorded as Practice Revenue and
during the calendar year.  In the event that it shall be finally determined
that the sum of the Base Service Fee and the Performance Fee are less than the
Base Draw paid by Oncology for such year, then such excess shall be deemed an
advance by Oncology, shall be recorded and reflected as a current account
payable by Response and an Excess Base Draw receivable by Oncology and shall be
settled by cash payment from Response to Oncology no later than the 15th day of
March of the next succeeding calendar year, or by such other settlement method
as may be mutually agreed upon.

                                   ARTICLE 9.
                                    RECORDS

      9.1.  Patient Records.  Upon termination of this Agreement, Oncology
shall retain all patient medical records maintained by Oncology or Response in
the name of Oncology.  Response shall, at its option, and if allowed under
Applicable Law be entitled to have reasonable access during normal business
hours to Oncology's patient medical records applicable to the period of
Response's performance under this Agreement.  Moreover, Oncology shall, at its
option, be entitled to retain copies of financial and accounting records

relating to all services performed by Oncology or Response under this
Agreement.  All parties agree to maintain the confidentiality of patient
identifying information and not to disclose such information except as may be
required or permitted by Applicable Law.

      9.2.  Records Owned by Response.  All records relating in any way to the
operation of a Clinic which are not the property of Oncology under the
provisions of Section 9.1 above, shall at all times be the property of
Response.

      9.3.  Access to Records.  During the term of this Agreement, and
thereafter, Oncology or its designee shall have reasonable access during normal
business hours to Oncology's and Response's financial records, including, but
not limited to, records of collections, expenses and disbursements as key by
Response in performing Response's obligations under this Agreement, and
Oncology may copy any and or all such records.

      9.4. Government Access to Records.  To the extent required by Section
1861(v)(1)(I) of the Social Security Act, each party shall, upon proper
request, allow the United States Department of Health and Human Services, the
Comptroller General of the United States, and their duly authorized
representatives access to this Agreement and to all books, documents, and
records necessary to verify the nature and extent of the costs of services
provided by either party under this Agreement, at any time during the term of
this Agreement and for an additional period of four (4) years following the
last date services are furnished under this Agreement.  If either party carries
out any of its duties under this Agreement through an agreement between it and
an individual or organization related to it or through a subcontract with an
unrelated party, that party to this Agreement shall require that a clause be
included in such agreement (the value of which is in excess of $10,000.00) to
the effect that until the expiration of four (4) years after the furnishing of
services pursuant to such agreement, the related organization shall make
available, upon request by the United States Department of Health and Human
Services, the Comptroller General of the United States, or any of their duly
authorized representatives, all agreements, books, documents, and records of
such related organization that are necessary to verify the nature and extent of
the costs of services provided under that agreement.

                            INSURANCE AND INDEMNITY

      10.1.  Insurance to be Maintained by Oncology.  Throughout the term of
this Agreement, Oncology shall maintain comprehensive professional liability
insurance with limits of not less than $500,000 per claim and with aggregate
policy limits of not less than $1,000,000 per physician and a separate limit
for Oncology.  Oncology shall be responsible for all liabilities in excess of
the limits of such policies.  Response shall have the option, with Oversight
Committee approval, of providing such professional liability insurance through
an alternative program, provided such program meets the requirements of the
Insurance Commissioner of the State of Florida.  Response shall reimburse
Oncology for any unearned professional liability insurance premiums paid by
Oncology to the extent not reimbursed or reimbursable by Oncology's insurance
carrier if Oncology's existing professional liability insurance program is
cancelled and replaced by a comparable professional liability insurance program
initiated by Response.

      10.2.  Insurance to be Maintained by Response.  Throughout the term of
this Agreement, Response shall make available, provide and/or maintain
comprehensive professional liability insurance for all Physician Employees who
are not physicians and all professional employees of Response, the cost of
which shall be a Clinic Expense, with limits as determined reasonable by
Response in its national program, and comprehensive general liability and
property insurance covering each Clinic premises and operations.

      10.3.  Additional Insureds.  Oncology and Response each agrees to use its
best efforts to have the other named as an additional insured on the their
respective professional liability insurance programs.

      10.4.  Indemnification Matters Involving Third Parties.  Oncology and
Response ("Indemnitor") shall indemnify, hold harmless and defend the other
("Indemnitee") from and against any and all liability, loss, damage, claim,
causes of action, and expenses (including reasonable attorneys' fees, except to
the extent limited below), whether or not covered by insurance, caused or
asserted to have been caused, directly or indirectly, by or as a result of the
acts (intentional or negligent) or omissions by, in the case of Oncology, by
any Physician Stockholder or other person acting under the supervision and
control thereof, or, in the case of Response, by any employee thereof who is
not acting under the supervision and control of a Physician Stockholder of
Oncology.

           (a) If any third party shall notify an Indemnitee with respect to
      any matter (a "Third Party Claim") which may give rise to a claim for
      indemnification under this Section 10.4, then the Indemnitee shall
      promptly notify the Indemnitor in writing; provided, however, that no
      delay on the part of the Indemnitee in notifying the Indemnitor shall
      relieve the Indemnitor from any obligation hereunder unless (and then
      solely to the extent) the Indemnitor is prejudiced by such delay.

           (b) The Indemnitor will have the right to defend the Indemnitee
      against the Third Party Claim with counsel of its choice satisfactory to
      the Indemnitee so long as (A) the Indemnitor notifies the Indemnitee in
      writing within 15 days after the Indemnitee has given notice of the Third
      Party Claim that the Indemnitor will indemnify the Indemnitee from and
      against the entirety of any Adverse Consequences (hereinbelow defined)
      the Indemnitee may suffer resulting from, arising out of, relating to, in
      the nature of, or caused by the Third Party Claim, (B) the Indemnitor
      provides the Indemnitee with evidence acceptable to the Indemnitee that
      the Indemnitor will have the financial resources to defend against the
      Third Party Claim and fulfill its indemnification obligations hereunder,
      (C) the Third Party Claim involves only money damages and does not seek
      an injunction or other equitable relief, (D) settlement of, or an adverse
      judgment with respect to, the Third Party Claim is not, in the good faith
      judgment of the Indemnitee, likely to establish a precedential custom or
      practice adverse to the continuing business interests of the Indemnitee,
      and (E) the Indemnitor conducts the defense of the Third Party Claim
      actively and diligently.

           (c) So long as the Indemnitor is conducting the defense of the Third
      Party Claim in accordance with Section 10.4(b) above, (A) the Indemnitee
      may retain separate co-counsel at its sole cost and expense and
      participate in the defense of the Third Party Claim, (B) the Indemnitee
      will not consent to the entry of any judgment or enter into any
      settlement with respect to the Third Party Claim without the prior
      written consent of the Indemnitor (not to be withheld unreasonably), and
      (C) the Indemnitor will not consent to the entry of any judgment or enter
      into any settlement with respect to the Third Party Claim without the
      prior written consent of the Indemnitee.

           (d) In the event any of the conditions in Section 10.4(b) above is
      or becomes unsatisfied, however, (A) the Indemnitee may defend against,
      and consent to the entry of any judgment or enter into any settlement
      with respect to, the Third Party Claim in any manner it may deem
      appropriate (and the Indemnitee need not consult with, or obtain any
      consent from, the Indemnitor in connection  therewith), (B) the
      Indemnitor will reimburse the Indemnitee promptly and periodically for
      the costs of defending against the Third Party Claim (including
      attorneys' fees and expenses), and (C) the Indemnitor will remain
      responsible for any Adverse Consequences the Indemnitee may suffer
      resulting from, arising out of, relating to, in the nature of, or caused
      by the Third Party Claim to the fullest extent provided in this Section
      10.4.

      10.5.  Determination of Adverse Consequences.  The parties hereto shall
take into account the time cost of money (using the Applicable Rate as the
discount rate) in determining Adverse Consequences for purposes of this Section
10.





                                      -19-

      10.6.  Other Indemnification Provisions.  The foregoing indemnification
provisions are in addition to, and not in derogation of, any statutory,
equitable, or common law remedy any party may have for breach of
representation, warranty, or covenant.

                                  ARTICLE 11.
                              TERM AND TERMINATION

      11.1.  Term of Agreement.  This Service Agreement shall be effective as
of the closing of the Stock Purchase and shall expire on December 31, 2035
unless earlier terminated pursuant to the terms hereof.

      11.2.  Extended Term.  Unless earlier terminated as provided for in this
Agreement, the term of this Agreement shall be automatically extended for
additional terms of five (5) years each, unless either party delivers to the
other party, not less than one hundred eighty (180) days prior to the
expiration of the preceding term, written notice of such party's intention not
to extend the term of this Agreement.

      11.3.  Response Event of Default.  The occurrence of any of the following
events shall constitute a default by Response (a "Response Event of Default")
under this Agreement, giving Oncology the right to the remedies set forth in
Section 11.5 below:

           (a)  the filing by Response of a petition in voluntary bankruptcy or
      an assignment by Response for the benefit of creditors, or upon other
      action taken or suffered, voluntarily or involuntarily, under any federal
      or state law for the benefit of debtors by Response, except for the
      filing of a petition in involuntary bankruptcy against Response which is
      dismissed within thirty (30) days thereafter.

           (b)  any material default by Response in the performance of any of
      its duties or obligations under this Agreement and such default shall
      continue for a period of sixty (60) days (fifteen (15) days in the case
      of Response's failure to provide required advances under the Receivables
      Line) after written notice thereof has been given to Response by
      Oncology.

           (c)  in the event Response shall, intentionally or in bad faith,
      misapply funds or assets of Oncology or commit a similar act which cause
      material harm to Oncology.

      11.4.  Oncology Event of Default.  The occurrence of any of the following
events shall constitute a default by Oncology (an "Oncology Event of Default")
under this Agreement, giving Response the right to the remedies set forth in
Section 11.6 below:

           (a)  the filing by Oncology of a petition in voluntary bankruptcy or
      an assignment by Oncology for the benefit of creditors, or upon other
      action taken or suffered, voluntarily or involuntarily, under any federal
      or state law for the benefit of debtors by Oncology, except for the
      filing of a petition in involuntary bankruptcy against Oncology which is
      dismissed within thirty (30) days thereafter.

           (b)  any material default by Oncology in the performance of any of
      its duties or obligations under this Agreement and such default shall
      continue for a period of ninety (90) days after written notice thereof
      has been given to Oncology by Response.

           (c)  the termination or suspension of Oncology's Medicare or
      Medicaid Provider Number as a result of the action or inaction of
      physicians, and such termination or suspension shall continue for  ninety
      (90) days, unless Oncology shall at that time be acting in good faith
      (and shall provide reasonable evidence of the action being taken) to
      reverse such termination or suspension.





                                      -20-
   21

      Notwithstanding any good faith effort on the part of Oncology to reverse
      such termination or suspension, if such termination or suspension shall
      not be reversed within ninety (90) days after occurrence, an event of
      default shall be deemed to have occurred.

           (d)  the termination or suspension of the Medicare or Medicaid
      Provider Numbers of a majority of the physicians employed by Oncology,
      and such termination or suspension shall continue for sixty (60) days,
      unless such physicians shall be acting in good faith (and shall provide
      reasonable evidence of the action being taken) to reverse such
      termination or suspension.  Notwithstanding any good faith effort on the
      part of any physicians to reverse such termination or suspension, if such
      termination or suspension with respect to that number of physicians
      required to cause a majority of such physicians to retain their Medicare
      or Medicaid Provider Numbers shall not be reversed within one hundred
      fifty (150) days after occurrence, an event of default shall be deemed to
      have occurred.

      11.5.  Remedies upon Response Event of Default.  Upon the occurrence of a
Response Event of Default, Oncology shall have the right to terminate this
Agreement by written notice to Response without any further obligation to
Response for Service Fees after the giving of such notice.  Upon termination of
this Agreement by Oncology, Response's obligations under that certain long-term
promissory note given by Response to the Stockholders in connection with the
Stock Purchase will terminate.  In addition to the foregoing, in such event
Oncology shall have the option to purchase from Response, and upon proper
exercise of such option by Oncology in the manner hereinbelow provided,
Response shall sell to Oncology, all assets and properties, tangible and
intangible (except that intangible assets shall not include any intangible
asset related to this Service Agreement), owned by Response and used by
Oncology in its medical practice ("Practice Assets") for a price, payable in
cash, equal to the fair market value of the Practice Assets.  Oncology shall
exercise such option by giving written notice to Response within sixty (60)
days after the occurrence of the Response Event of Default.  Upon delivery of
such exercise, Response and Oncology shall negotiate in good faith the fair
market value of the assets to be acquired.  In the event that, after at least
fifteen (15) days of good faith negotiation, Response and Oncology shall not
have agreed upon the fair market value of the Practice Assets, each party shall
select an appraiser who shall provide an evaluation report with respect to the
fair market value of the Practice Assets.  If the valuations of the appraisers
are within $25,000.00 of each other, then the lowest appraisal shall be deemed
the fair market value of the Practice Assets, and Oncology shall purchase the
Practice Assets for such value.  If the valuation of the appraisers are more
than $25,000.00 different, then the two appraisers shall agree upon a third
appraiser, and the average value set forth in the three appraisals shall be
deemed the fair market value of the Practice Assets, and Oncology shall
purchase the Practice Assets for such value.

      11.6.  Remedies upon Oncology Event of Default.  Upon the occurrence of
an Oncology Event of Default, Response shall have the right to terminate this
Agreement by written notice to Oncology, and Oncology shall have no further
obligation to Response for Service Fees after the date such notice is received.
In such event, Response's obligations under that certain long-term promissory
note given by Response to the Stockholders in connection with the Stock
Purchase shall terminate.  In addition, in such event, Oncology shall be
obligated to pay to Response the Liquidated Damages Amount in complete
satisfaction of any and all damages suffered by Response hereunder.  Such
Liquidated Damages Amount shall be payable by Oncology in cash within sixty
(60) days after occurrence of the Oncology Event of Default.  Each Stockholder
hereby severally, and not jointly, guarantees the foregoing obligation of
Oncology and agrees to pay to Response his pro rata share of the Liquidated
Damages Amount provided that and to the extent he is a Remaining Physician
Stockholder for purposes of this Agreement, with the pro rata share being equal
to the portion of the Liquidated Damages Amount not paid by Oncology divided by
the number of Remaining Physician Stockholders as of the date of occurrence of
an Oncology Event of Default.  Moreover, in such event Oncology shall have the
option to purchase from Response, and upon proper exercise of such option by
Oncology in the manner hereinbelow provided, Response shall sell to Oncology,
all Practice Assets for a price, payable in cash, equal to the fair market
value of the Practice Assets.  Oncology shall exercise such option by giving





                                      -21-
   22

written notice to Response within sixty (60) days after the occurrence of the
Response Event of Default.  Upon delivery of such exercise, Response and
Oncology shall negotiate in good faith the fair market value of the assets to
be acquired.  In the event that, after at least fifteen (15) days of good faith
negotiation, Response and Oncology shall not have agreed upon the fair market
value of the Practice Assets, each party shall select an appraiser who shall
provide an evaluation report with respect to the fair market value of the
Practice Assets.  If the valuations of the appraisers are within $25,000.00 of
each other, then the lowest appraisal shall be deemed the fair market value of
the Practice Assets, and Oncology shall purchase the Practice Assets for such
value.  If the valuation of the appraisers are more than $25,000.00 different,
then the two appraisers shall agree upon a third appraiser, and the average
value set forth in the three appraisals shall be deemed the fair market value
of the Practice Assets, and Oncology shall purchase the Practice Assets for
such value.

      11.7.  Closing of Repurchase by Oncology and Effective Date of
Termination.  Oncology shall pay cash for Practice Assets repurchased
hereunder.  The amount of the purchase price shall be reduced by the amount of
debt and liabilities of Response assumed by Oncology and shall also be reduced
by any payment Response has failed to make under this Agreement, provided that
such payments or obligations are not otherwise accounted for in the liabilities
assumed by Oncology in connection with the repurchase described herein.  The
closing date for the repurchase shall be determined by Oncology, but shall in
no event occur later than 180 days from the date of the notice of termination.
In the event of exercise of such option, each party shall use its best efforts
to obtain such consents and authorizations to such transaction as may be
required by Applicable Law or otherwise.  In such event, Response shall execute
and deliver to Oncology such assignments to leases and other contracts and such
bills of sale and other transfer or closing documents necessary to effect such
transaction.  Oncology shall execute and deliver to Response such officers'
certificates, assumption agreements and other closing documents necessary to
close such transaction.

                                   ARTICLE 12
                         DAMAGE AND LOSS; CONDEMNATION

      12.1.  Use of Insurance Proceeds.  All insurance or condemnation proceeds
payable by reason of any physical loss of any of the improvements comprising
the facilities or the furniture, fixtures and equipment used by the Clinics,
shall be available for the reconstruction, repair or replacement, as the case
may be, of any damage, destruction or loss.  The Oversight Committee, in
consultation with Oncology, shall review and approve such reconstruction,
repair or replacement.

      12.2.  Temporary Space.  In the event of substantial damage to or the
condemnation of a significant portion of the facilities, Response shall use its
best efforts to provide temporary facilities until such time as the facilities
can be restored or replaced.

                                   ARTICLE 13
                   REPRESENTATIONS AND WARRANTIES OF ONCOLOGY

      Oncology represents, warrants, covenants and agrees with Response that:

      13.1.  Validity.  Oncology is a professional association duly organized,

consummate the transactions contemplated hereby.

      13.2.  Litigation.  There is no suit, action, proceeding at law or in
equity, arbitration, administrative proceeding or other proceeding  pending, or
threatened against, or affecting Oncology, or any of the assets to be conveyed
hereunder, or to the best of Oncology's knowledge, any hematology or oncology
provider or other health care professional associated with or employed by
Oncology as pertains to any claim involving the





                                      -22-
   23

providing of health care related services, and to the best of Oncology's
knowledge there is no basis for any of the foregoing.

      13.3.  Permits.  Oncology and all physicians and other health care
professionals associated with or employed by Oncology have all permits and
licenses and other Necessary Authorizations required by all Applicable Laws,
except where failure to secure such licenses, permits and other Necessary
Authorizations does not have a material adverse effect; have made all
regulatory filings necessary for the conduct of Oncology's business; and are

      13.4.  Authority.  The execution of this Agreement and the consummation

Oncology, enforceable in accordance with its terms.  Oncology has obtained all
third-party consents necessary to enter into and consummate the transaction
contemplated by this Agreement.  Neither the execution and delivery of this
Agreement, the consummation of the transactions contemplated hereby, nor
compliance by Oncology with any of the provisions hereof, will:

           (a)  violate or conflict with, or result in a breach of any
      provision of, or constitute a default (or an event which, with notice or
      lapse of time or both, would constitute a default) under, or result in
      the termination of, or accelerate the performance required by, or result
      in the creation of, any lien, security interest, charge or encumbrance
      upon any of the assets to be conveyed hereunder, Oncology's charter or
      bylaws or any of the terms, conditions or provisions of any note, bond,
      mortgage, indenture, deed of trust, license, agreement or other
      instrument or obligation to which Oncology is a party, or by which either
      Oncology or any of the assets to be conveyed hereunder is bound; or

      13.5.  Compliance with Applicable Laws.  To the best of Oncology's
knowledge and belief, Oncology has operated in compliance with all federal,
state, county and municipal laws, ordinances and regulations applicable thereto
and neither Oncology nor any physician or other Person associated with or
employed by Oncology has received payment or any remuneration whatsoever to
induce or encourage the referral of patients or the purchase of goods and/or
services as prohibited under 42 U.S.C. Section 1320a-7b(b), or otherwise
perpetrated any Medicare or Medicaid fraud or abuse, nor has any fraud or abuse
been alleged within the last five (5) years by any Governmental Authority, a
carrier or a Third Party Payor.

      13.6.  Health Care Compliance.  Oncology is presently participating in or
otherwise authorized to receive reimbursement from or is a party to Medicare,
Medicaid, and other Third-Party Payor Programs.  All necessary certifications
and contracts required for participation in such programs are in full force and
effect and have not been amended or otherwise modified, rescinded, revoked or
assigned as of the date hereof, and no condition exists or event has occurred
which in itself or with the giving of notice or the lapse of time or both would
result in the suspension, revocation, impairment, forfeiture or non-renewal of
any such Third Party Payor Program.  Oncology is in full compliance with the
requirements of all such Third Party Payor Programs applicable thereto.

      13.7.  Fraud and Abuse.  Oncology and persons and entities providing
professional services for Oncology, have not, to the knowledge of Oncology,
after due inquiry, engaged in any activities which are prohibited by or are in
violation of the rules, regulations, policies, contracts or laws pertaining to
any Third Party Payor Program, or which are prohibited by rules of professional
conduct ("Governmental Rules and Regulations"), including but not limited to
the following:  (a) knowingly and willfully making or causing to be made a
false statement or representation of a material





                                      -23-
   24

fact in any application for any benefit or payment; (b) knowingly and willfully
making or causing to be made any false statement or representation of a
material fact for use in determining rights to any benefit or payment; (c)
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
Oncology's own behalf or on behalf of another, with intent to fraudulently
secure such benefit or payment; or (d) knowingly and willfully 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 or any item or service for
which payment may be made in whole or in part by Medicare or Medicaid, 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 Medicaid.

      13.8.  Oncology Compliance.  Oncology has all licenses necessary to
operate the Clinic in accordance with the requirements of all Applicable Laws
and has all Necessary Authorizations for the use and operation, all of which
are in full force and effect.  There are no outstanding notices of deficiencies
relating to Oncology issued by any Governmental Authority or Third Party Payor
requiring conformity or compliance with any Applicable Law or condition for
participation of such Governmental Authority or Third Party Payor, and after
reasonable and independent inquiry and due diligence and investigation,
Oncology has neither received notice nor has any knowledge or reason to believe
that such Necessary Authorizations may be revoked or not renewed in the
ordinary course.

      13.9.  Rates and Reimbursement Policies.  The jurisdiction in which
Oncology is located does not currently impose any restrictions or limitations
on rates which may be charged to private pay patients receiving services
provided by Oncology. Oncology does not have any rate appeal currently pending
before any Governmental Authority or any administrator of any Third Party Payor
Program.  Oncology has no knowledge of any Applicable Law which has been
enacted, promulgated or issued within the eighteen (18) months preceding the
date of this Agreement or any such legal requirement proposed or currently
pending in the jurisdiction in which Oncology is located which could have a
material adverse effect on Oncology or may result in the imposition of
additional Medicaid, Medicare, charity, free care, welfare, or other discounted
or government assisted patients at Oncology or require Oncology to obtain any
necessary authorization which Oncology does not currently possess.

         13.10.  Full Disclosure.  When considered in the context of all
information contained herein, no representation or warranty made by Oncology in
this Agreement contains or will contain any untrue statement of a material
fact.  All representatives and warranties contained in this Agreement are true
and correct as of the date of their Agreement and shall remain true and correct
throughout the term of this Agreement.

         13.11.  Exhibits.  All the facts recited in Exhibits annexed hereby
(as updated as of the effective date hereof) shall be deemed to be
representations of fact by Oncology as though recited in this Article 13.

         does Oncology now use, any fictitious or trade name.  Oncology shall
         notify Response in writing thirty (30) days prior to any change in any
         such name.

                 (b)  Oncology shall, effective as of the date hereof, be
         deemed to have granted (and Oncology does hereby grant) to Response a
         first priority security interest in and to that certain promissory
         note of even date herewith, and to the proceeds thereof, to secure the
         payment of the Fixed Portion of the Base Service Fee; and this
