Date (the "Closing Price"). In the event that the Closing Price exceeds Three
and No/100 Dollars ($3.00) and GCOA or the Physician Owners elect to deliver
cash in lieu of all or part of the SCN Shares, then GCOA or the Physician
Owners, as applicable, shall deliver to SCN contemporaneously with the delivery
of such cash written evidence that the SCN Shares for which such election to pay
cash was made were disposed of prior to the date of this Agreement in a broker
assisted trade. GCOA and the Physician Owners agree that any SCN Shares
delivered pursuant to this SECTION 2.2 shall be properly endorsed for transfer
by GCOA or the Physician Owners, together with appropriate signature guarantees,
and shall be delivered by GCOA and/or the Physician Owners.

         II.3  Accounting; True-Up; Dispute Resolution.

                  (a) No less than five (5) business days prior to Closing, SCN
         shall deliver to GCOA the most recently prepared month-end balance
         sheet (the "Most Recent Balance Sheet") stating the Book Value of the
         Purchased Assets and Assumed Liabilities. Within sixty (60) days from
         the Closing Date, SCN shall prepare a balance sheet (the "Closing Date
         Balance Sheet") stating the Book Value of the Purchased Assets and
         Assumed Liabilities as of the Closing Date. In the event SCN determines
         that the Asset Purchase Price (as determined in accordance with the
         Closing Date Balance Sheet) is greater than the amount paid by GCOA and
         the Physician Owners at Closing in accordance with the provisions of
         SECTION 2.1 of this Agreement, then GCOA and the Physician Owners shall
         pay to SCN such excess in cash within two (2) days of the date SCN
         furnishes to GCOA and the Physician Owners the Asset Purchase Price
         computation. In the event that SCN determines that the Asset Purchase
         Price (as determined in accordance with the Closing Date Balance Sheet)
         is less than the amount paid by GCOA and the Physician Owners to SCN at
         Closing in accordance with the provisions of SECTION 2.1 of this
         Agreement, then SCN shall pay to GCOA and the Physician Owners such
         excess in cash within two (2) days of the date SCN furnishes to GCOA
         and the Physician Owners the Asset Purchase Price computation.

                  (b) If SCN and GCOA are unable to resolve any disagreement
         within twenty (20) days after SCN's receipt of such notice of
         disagreement, either SCN or GCOA may give notice (an "Arbitration
         Notice") to the other Party of an intent to submit such disagreement to
         a certified independent public accounting firm that is nationally
         recognized (the "Independent Accounting Firm") and mutually agreeable
         to SCN and GCOA. If SCN and GCOA cannot agree upon such election within
         twenty (20) days after delivery of the Arbitration Notice, the
         Independent Accounting Firm shall be selected by lot from among the
         five largest independent public accounting firms in the United States,
         excluding SCN's principal auditors. The dispute shall be immediately
         submitted by GCOA and SCN to the Independent Accounting Firm for
         resolution of such dispute within twenty (20) days after submission to
         the Independent Accounting Firm. At the time of the submission of such
         dispute to the Independent Accounting Firm for resolution, SCN shall
         file with the Independent Accounting Firm a written statement of its
         position with regard to any matters in dispute, at which time GCOA
         shall have ten (10) days to respond in writing to SCN's position. Upon
         receipt of written position statements by each of SCN and GCOA, the
         Independent Accounting Firm shall resolve the dispute in accordance
         with GAAP. The decision of the Independent Accounting Firm shall be
         final and binding upon all Parties hereto. Each Party shall bear its
         own expenses, including expenses of its accountants and attorneys in
         connection with the resolution of any such dispute; provided, however,
         the fees and expenses of the Independent Accounting Firm shall be paid
         by GCOA.

         II.4 Assumption of Term Debt and Assumed Liabilities. Except as

         to GCOA or the Physician Owners at any time prior to the Closing Date
         (A) in the event GCOA or the Physician Owners has breached any
         representation, warranty, or covenant contained in this Agreement in
         any material respect, SCN has notified GCOA or the Physician Owners of
         the breach, and the breach has continued without cure for a period of
         ninety (90) days after the notice of breach or (B) if the Closing shall
         not have occurred on or before December 31, 1998, by reason of the
         failure of any condition precedent under SECTION 6.2 hereof (unless the
         failure results primarily from SCN's breaching any representation,
         warranty, or covenant contained in this Agreement).

         VIII.2 Effect of Termination. If any Party terminates this Agreement
pursuant to SECTION 8.1 above, all rights and obligations of the Parties
hereunder shall terminate without any liability of any Party to any other Party
(except for any liability of any Party then in breach). Notwithstanding the
foregoing, in the event the transaction contemplated by this Agreement is not
consummated due to the fault, or failure to perform hereunder by GCOA or the
Physician Owners then GCOA and the Physician Owners agree to reimburse SCN for
SCN's out-of-pocket expenses, including but not limited to professional fees.

                                   ARTICLE IX.

resulting from or arising out of the breach, untruth or inaccuracy of any
representation, warranty or covenant of GCOA or the Physician Owners set forth
in this Agreement, or (ii) resulting from or arising out of any of the Assumed
Liabilities. In addition to any indemnification rights granted to SCN under this
Agreement, SCN shall continue to be entitled to any indemnification under any

Physician Owners may participate in and at their election, or at the request of
SCN, assume the defense of any such suit, action or proceeding at GCOA or the
Physician Owners' expense. Neither GCOA nor the Physician Owners shall be liable
under SECTION 9.1 for any settlement effected without their consent of any
claim, litigation or proceeding in respect of which indemnity may be sought
under SECTION 9.1, which consent shall not be unreasonably withheld.

         IX.3 General Indemnification by SCN. SCN agrees to and shall defend,
indemnify and hold harmless GCOA, its successors and assigns, officers and
managers, from or against any Loss resulting from or arising out of the breach,

of the Physician Owners, assume the defense of any such suit, action or
proceeding at SCN's expense. SCN shall not be liable under SECTION 9.3 for any
settlement effected without its consent of any claim, litigation or proceeding
in respect of which indemnity may be sought hereunder, which consent shall not
be unreasonably withheld.

                                  MISCELLANEOUS

         X.1 Survival. The representations, warranties, and covenants of the
Physician Owners, GCOA and SCN contained in this Agreement and the
indemnifications contained herein shall survive the Closing. Except as provided
in this SECTION 10.1 below, no claim for indemnification with respect to any
alleged misrepresentation or breach of warranty may be made after three (3)
years following the Closing Date. SCN shall be entitled to indemnification for
(i) claims for breaches of representations, warranties or covenants relating to
matters involving the payment of taxes (including interest and/or penalties
thereon), (ii) claims arising from reimbursement of any amounts to Third Party
Payors (including interest and penalties thereon), and (iii) claims relating to
a matter involving compliance with Applicable Laws as described in ARTICLE IV
and ARTICLE V above and such right of indemnification shall survive for the
applicable statute of limitations for the underlying claim asserted. In
addition, any matter to which indemnification pertains and with respect to which
a claim has been asserted or threatened following the Closing Date and prior to
termination of the applicable survival period shall, notwithstanding the
expiration of the applicable survival period, continue to be subject to the
indemnification under this Agreement.

         X.2 No Third-Party Beneficiaries. This Agreement shall not confer any
rights or remedies upon any Person other than the Parties and their respective
successors and permitted assigns.

         X.3 Entire Agreement. Except as otherwise set forth herein, this
Agreement (including the documents referred to herein) constitutes the entire
agreement between the Parties and supersedes any prior understandings,
agreements, or representations by or between the Parties, written or oral, to
the extent they related in any way to the subject matter hereof.

         X.4 Succession and Assignment. This Agreement shall be binding upon and
inure to the benefit of the Parties named herein and their respective successors
and permitted assigns. No Party may assign either this Agreement or any of its
rights, interests, or obligations hereunder without the prior written approval
of the other Parties.

         X.5 Counterparts. This Agreement may be executed in one or more
counterparts, each of which shall be deemed an original but all of which
together will constitute one and the same instrument.

construed in accordance with the domestic laws of the State of Colorado without
giving effect to any choice or conflict of law provision or rule (whether of the
State of Colorado or any other jurisdiction) that would cause the application of
the laws of any jurisdiction other than the State of Colorado. Each of the
parties submits to the jurisdiction of any state or federal court sitting in
Denver, Colorado, in any action or proceeding arising out of or relating to this
Agreement and agrees that all claims in respect of the action or proceeding may
be heard and determined in any such court. Each party also agrees not to bring
any action or proceeding arising out of or relating to this Agreement in any
other court. Each of the parties waives any defense of inconvenient forum to the
maintenance of any action or proceeding so brought and waives any bond, surety,
or other security that might be required of any other party with respect
thereto.

         X.9 Amendments and Waivers. The Parties may mutually amend any
provision of this Agreement at any time prior to the Effective Time with the
prior authorization of their respective boards of directors, or equivalent

                                       14
<PAGE>   19

misrepresentation, or breach of warranty or covenant hereunder, whether

default, misrepresentation, or breach of warranty or covenant hereunder or
affect in any way any rights arising by virtue of any prior or subsequent such
occurrence.

         X.10 Severability. Any term or provision of this Agreement that is
invalid or unenforceable in any situation in any jurisdiction shall not affect
the validity or enforceability of the remaining terms and provisions hereof or
the validity or enforceability of the offending term or provision in any other
situation or in any other jurisdiction.

         X.11 Expenses. Each of the Parties will bear its own costs and expenses
(including legal fees and expenses) incurred in connection with this Agreement
and the transactions contemplated hereby.

         X.12 Construction. The Parties have participated jointly in the
negotiation and drafting of this Agreement. In the event an ambiguity or
question of intent or interpretation arises, this Agreement shall be construed
as if drafted jointly by the Parties and no presumption or burden of proof shall
arise favoring or disfavoring any Party by virtue of the authorship of any of
the provisions of this Agreement. Any reference to any federal, state, local, or
foreign statute or law shall be deemed also to refer to all rules and
regulations promulgated thereunder, unless the context otherwise requires. The
word "including" shall mean including without limitation.

         X.13 No Referrals Required. The Parties agree that no part of this
Agreement shall be construed to induce or encourage the referral of patients or
the purchase of health care services or supplies. The Parties acknowledge that
there is no requirement under this Agreement or any other agreement between GCOA
and SCN that any party refer any patients to any health care provider or
purchase any health care goods or services from any source. Additionally, no
payment under this Agreement is in return for the referral of patients, if any,
or in return for purchasing, leasing or ordering services from SCN or any of
SCN's affiliates. The Parties may refer patients to any company or person
providing services and will make such referrals, if any, consistent with
professional medical judgment and the needs and wishes of the relevant patients.

         X.14 Incorporation of Exhibits and Schedules. The Exhibits and
Schedules identified in this Agreement are incorporated herein by reference and
made a part hereof.

         X.15 Transactions with Affiliated Practices. In the event that SCN
shall within a period commencing on the Closing Date and ending on December 31,
1999 close a transaction with an Affiliated Practice which is substantially
similar to the restructuring transaction contemplated by this Agreement (a
"Restructuring Transaction"), and, taken as a whole, the financial terms of such
other Restructuring Transaction are materially more favorable to such Affiliated
Practice (and its Physician Owners) than the financial terms, taken as a whole,
of the restructuring transaction contemplated by this Agreement, then in such
event SCN shall modify the financial terms of this Agreement in such manner as
SCN shall reasonably determine so that the financial terms of the restructuring
transaction contemplated by this Agreement for GCOA and the Physician Owners
shall be no less favorable, when taken as a whole, than the Restructuring
Transaction undertaken with respect to any other Affiliated Practice. For these
purposes, the term "Affiliated Practice" shall refer to any physician medical
practice which, as of December 1, 1998, had in effect with SCN an agreement
substantially similar to the Service Agreement.

         THIS BILL OF SALE is made and delivered by and from SPECIALTY CARE

         In connection therewith, for good and valuable consideration, the

assigns, and shall inure to the benefit of Purchaser, its successors and
assigns. This instrument shall be effective as to the transfer of all of the
Purchased Assets as of the Closing Date.

         Nothing herein contained shall be deemed or construed as an assumption
by Purchaser of, or to impose upon Purchaser, any liabilities or obligations of
Seller, except as otherwise provided in that certain Assignment and Assumption
Agreement of even date herewith.

         This Bill of Sale shall be governed by and construed in accordance with

                                     RELEASE


         THIS RELEASE is being executed and delivered in accordance with SECTION
7.2(C) of the Restructure Agreement dated December 31, 1998 (the "Agreement") by
and among SPECIALTY CARE NETWORK, INC., a Delaware corporation ("SCN"), GREATER
CHESAPEAKE ORTHOPAEDIC ASSOCIATES, L.L.C., a Maryland limited liability company
("GCOA") and the Physician Owners. Capitalized terms used in this Release
without definition have the respective meanings given to them in the Agreement.

         GCOA and the Physician Owners acknowledge that execution and delivery
of this Release is a condition to SCN's obligation to consummate the transaction
contemplated by the Agreement and to amend and restate the Service Agreement as
the Management Services Agreement, and that SCN is relying on this Release in
connection with the foregoing.

         GCOA and the Physician Owners, for good and valuable consideration, the
receipt and sufficiency of which is hereby acknowledged and intending to be
legally bound, in order to induce SCN to consummate all transactions
contemplated by the Agreement, hereby agree as follows:

         GCOA and the Physician Owners on behalf of GCOA and themselves
individually and each of their Related Persons, hereby releases and forever
discharges SCN and each of its respective individual, joint or mutual, past,
present and future representatives, affiliates, stockholders, controlling
persons, subsidiaries, employees, agents, successors, directors and assigns
(individually, a "Releasee" and collectively, "Releasees") from any and all
claims, demands, Proceedings, causes of action, Orders, obligations, contracts,
agreements, debts and liabilities whatsoever, whether known or unknown,
suspected or unsuspected, both at law and in equity, which each of GCOA and the
Physician Owners or any of their respective Related Persons now has, have ever
had or may hereafter have against the respective Releasees arising
contemporaneously with or prior to the Closing Date or on account of or arising
out of any matter, cause or event occurring contemporaneously with or prior to
the Closing Date, including, but not limited to, any rights to indemnification
or reimbursement from SCN, whether pursuant to the Asset Exchange Agreement,
Service Agreement, and any other agreement entered into prior to the date of the
Agreement, and whether or not relating to claims pending on, or asserted after,
the Closing Date; provided, however, that nothing contained herein shall operate
to release any obligations of SCN accruing after the Closing Date under the
Agreement or the Management Services Agreement, which are to remain in effect
after Closing.

         GCOA and the Physician Owners hereby irrevocably covenants to refrain
from, directly or indirectly, asserting any claim or demand, or commencing,
instituting or causing to be commenced, any proceeding of any kind against any
Releasee, based upon any matter purported to be released hereby.

         Without in any way limiting any of the rights and remedies otherwise
available to any Releasee, each GCOA and the Physician Owners, jointly and
severally, shall indemnify and hold harmless each Releasee from and against all
loss, liability, claim, damage (including incidental and consequential damages)
or expense (including costs of investigation and defense and reasonable
attorney's fees) whether or not involving third party claims, arising directly
or indirectly from or in connection with (i) the assertion by or on behalf of
GCOA or the Physician Owners or any of their Related Persons of any claim or
other matter purported to be released pursuant to this Release, and (ii) the
assertion by any third party of any claim or demand against any Releasee which
claim or demand arises directly or indirectly from, or in connection with, any
assertion by or on behalf of GCOA or the Physician Owners or any of their
Related Persons against such third party of any claims or other matters
purported to be released pursuant to this Release.

         If any provision of this Release is held invalid or unenforceable by
any court of competent jurisdiction, the other provisions of this Release will
remain in full force and effect. Any provision of this Release held invalid or
unenforceable only in part or degree will remain in full force and effect to the
extent not held invalid or unenforceable.
