                  (iv) Directors and Officers. The directors and officers of SCN
         in office at and as of the Effective Time will remain the directors and
         officers of the Surviving Corporation (retaining their respective
         positions and terms of office).

                  (v) Conversion of OSMC Shares. At and as of the Effective
         Time, each of the issued and outstanding OSMC Shares shall be converted
         into the right to receive 4,115.910751 SCN Shares (the "Conversion
         Ratio"). The Conversion Ratio shall be subject to equitable adjustment
         in the event of any stock split, stock dividend, reverse stock split,
         or other change in the number of OSMC Shares or SCN Shares outstanding.
         Each OSMC Stockholder may, in his sole and absolute discretion, elect
         (a "Cash/Debt Election") to convert, at and as of the Effective Time,
         and, upon such election, each OSMC Share owned by him shall be
         converted into the right to receive (A) a number of SCN Shares equal to
         the Conversion Ratio times a percentage between 50% and 100% ("Stock
         Percentage") multiplied by the number of OSMC Shares owned by him, plus
         (B) a cash payment per OSMC Share ("Cash Consideration"), or, in the
         alternative, an SCN subordinated unsecured convertible debenture (a
         "Debenture" the form of which is set forth as Exhibit 2(d)(v)(1)
         hereto), or any combination thereof, per OSMC Share equal to the
         Conversion Ratio times the reciprocal of the Stock Percentage times the
         Average SCN Price. In the alternative, each OSMC Stockholder may elect
         (a "Cash/Warrant Election") to convert, at and as of the Effective
         Time, and, upon such election, each OSMC Share owned by him shall be
         converted into the right to receive (1) a number of SCN Shares equal to
         the Conversion Ratio times a Stock Percentage multiplied by the number
         of OSMC Shares owned by him, plus (2) Cash Consideration per OSMC Share
         equal to the Conversion Ratio, times a percentage between 0% and 25%
         ("Cash/Warrant Percentage"), times 90% of the Average SCN Price, plus
         (3) a warrant (a "Warrant", the form of which is set forth as Exhibit
         2(d)(v)(2) hereto) to purchase .08114 SCN Shares per dollar of Cash


 

                                      - 5 -

         Consideration determined pursuant to clause (2) above, plus (4)
         additional Cash Consideration or Debentures ("Residual Consideration"),
         or any combination thereof, equal to the Conversion Ratio times the
         Average SCN Stock Price times 100% minus the sum of the Stock
         Percentage and Cash Option Percentage elected by the OSMC Stockholder.
         A Cash/Debt Election or Cash/Warrant Election shall be made in writing
         (the "Election Notice") delivered to SCN by the electing OSMC
         Stockholder no later than 2:00 p.m. Central Standard Time on March 27,
         1997. The Cash/Debt Election shall be submitted on the form attached as
         Exhibit 2(d)(v)(3) hereto, and the Cash/Warrant Election shall be
         submitted on the form attached as Exhibit 2(d)(v)(4) hereto. At
         Closing, SCN shall cause to be issued and/or delivered to the OSMC
         Stockholders certificates representing the SCN Shares to be issued in
         the Merger, as finally determined, together with the Cash
         Consideration, Debentures and Warrants, as applicable, into which the
         OSMC Shares shall have been converted at the Effective Time. The
         foregoing SCN Shares and, if elected, Cash Consideration, Debentures
         and Warrants deliverable to the OSMC Stockholders in the Merger is
         sometimes herein referred to as the "Merger Consideration."

                  (vi) SCN Shares. Each SCN Share issued and outstanding at and
         as of the Effective Time will remain issued and outstanding and shall
         be unaffected by the Merger.

         (e) No Fractional Shares. No fractional SCN Shares shall be issued
pursuant to the Merger. In lieu of the issuance of any such fractional SCN
Shares, cash adjustments will be paid to holders in respect of any fractional
SCN Shares that would otherwise be issuable. The amount of such adjustment shall
be the product of such fraction of a SCN Share multiplied by $9.86.

         (f) Contingent Merger Consideration. In addition to the Merger
Consideration, if the Hospital JV is formed and becomes operational on or before
May 15, 1997, the OSMC Stockholders shall be entitled to receive the Additional
Merger Consideration. The Contingent Merger Consideration shall be payable in
the same percentages of SCN Shares, Cash Consideration (plus Warrants, if
applicable) and Debentures as the OSMC Stockholders shall have elected pursuant
to Section 2(d)(v) above. The parties shall, at Closing, execute and deliver an
escrow agreement (the "Escrow Agreement") pursuant to which John A. Good, Esq.
shall be appointed as escrow agent (the "Escrow Agent"), and SCN shall deliver
to the Escrow Agent a combination of SCN Shares, Cash Consideration (plus
Warrants, if applicable) and/or Debentures equal to, in the aggregate, the
Parties' best estimate, determined as of the Closing Date, of the Contingent
Merger Consideration. For this purpose, the number of SCN Shares shall be
determined based on the Average SCN Price. On the date which a definitive
agreement for the Hospital JV (the "Escrow Release Date") is executed and
delivered, the amount of Contingent Merger Consideration shall be determined by
the parties based on the definitive agreement for the Hospital JV. On the Escrow
Release Date, the Escrow Agent shall deliver to the OSMC Stockholders the
escrowed consideration (with SCN Shares being valued at the price set forth in
the second preceding sentence) up to, but not in excess of, the Contingent
Merger Consideration, with any remaining escrowed consideration being returned
to SCN, all pursuant to the Escrow Agreement.

         3. Representations and Warranties of OSMC and OSMC Stockholders. OSMC
and the OSMC Stockholders, jointly and severally, represent and warrant to SCN
that the statements contained in this Section 3 are correct and complete as of

         compensation in excess of $25,000 or providing severance benefits;

                  (viii) any agreement pursuant to which OSMC has advanced or
         loaned any amount to any of its directors, officers, and employees;

                  (ix) any agreement pursuant to which the consequences of a

forth in Section 3(i) of the Disclosure Schedule, no notice of this Agreement or
consent of any third party is required in order for OSMC to execute and deliver

assignment to SCN at Closing, the agreement will continue to be legal, valid,
binding, enforceable, and in full force and effect on identical terms; (C) no
party is in breach or default, and no event has occurred which with notice or
lapse of time would constitute a breach or default, or permit termination,

repudiated any provision of the agreement.

         (j) Insurance; Malpractice. Section 3(j) of the Disclosure Schedule
contains a list and brief description of all policies or binders of fire,
liability, product liability, workers compensation, health and other forms of
insurance policies or binders currently in force insuring against risks which

3(j) of the Disclosure Schedule contains a description of all current
malpractice liability insurance policies of OSMC Stockholders, OSMC and OSMC's
professional employees and all predecessor policies in effect since February 1,

have, in the last seven (7) years, filed a written application for any insurance
coverage relating to OSMC's business or property which has been denied by an
insurance agency or carrier. OSMC, OSMC's professional employees and the OSMC
Stockholders have been continuously insured for professional malpractice claims
during the same period. Section 3(j) of the Disclosure Schedule also sets forth
a list of all claims for any insured loss in excess of Five Thousand Dollars

liability claims. None of OSMC, OSMC's professional employees or the OSMC
Stockholders is in material default with respect to any provision contained in
any such policy and none of them has failed to give any notice or present any
claim under any such policy in due and timely fashion.

         (k) No Changes Prior to Closing Date. During the period from December
31, 1996 through the date hereof, OSMC has not (i) incurred any liability or
obligation of any nature (whether known or unknown, asserted or unasserted,
absolute or contingent, accrued or unaccrued, liquidated or unliquidated and
whether due or to become due), except in the Ordinary Course of Business, (ii)
written off as uncollectible any notes or accounts receivable, except write-offs
in the Ordinary Course of Business charged to applicable reserves, none of which
individually or in the aggregate is material to OSMC, (iii) conducted its
business in such a manner so as to materially increase its accounts payable or
so as to materially decrease its accounts receivable, (iv) granted any increase
in the rate of wages, salaries, bonuses, or other remunerations of any employee,
except in the Ordinary Course of Business, (v) canceled or waived any claims or
rights of substantial value, (vi) made any change in any method of accounting,
(vii) otherwise conducted its business or entered into any transaction, except
in the usual and ordinary manner and in the Ordinary Course of Business, (viii)
agreed, whether or not in writing, to do any of the foregoing, or (ix) disposed
of its assets other than in the Ordinary Course of Business.

         (l) Title; Condition. Section 3(l) of the Disclosure Schedule contains
a complete, true and correct list of those assets which are material to the
business or operations of OSMC (the "Practice Assets"). OSMC has good and
marketable title to all of the Practice Assets subject to no mortgage, pledge,
lien, lease, conditional sales agreement, option, right of first refusal or any
other encumbrance or charge, including taxes. OSMC agrees to remove all security
interests reflected on any search of public records, if any, prior to the
Effective Time and remove any other security interest filed with respect to the
Practice Assets between the date of such search of public records and the
Effective Time.

         (m) Litigation. There is no suit, action, proceeding at law or in
equity, arbitration, administrative proceeding or other proceeding or
investigation by any governmental entity pending, or threatened against, or
affecting OSMC or any of the Practice Assets, or any physician or other health
care professional engaged or employed by OSMC, and there is no basis for any of
the foregoing. None of the actions, suits, proceedings, hearings, and
investigations set forth in Section 3(m) of the Disclosure Schedule could result
in any material adverse change in the operations, results of operations, or
future prospects of the business assets to be operated by SCN after the Closing.

         (n) Permits and Licenses. OSMC and all physicians and other health care
professionals engaged or employed by OSMC have all permits and licenses required
by all applicable laws; have made all regulatory filings necessary for the
conduct of OSMC's business; and are not in violation of any of said permitting
or licensing requirements.

         (o) Tax Matters. All federal, state and other tax returns of OSMC
required by law to be filed have been timely filed, and OSMC has paid or
adequately provided for all taxes (including taxes on properties, income,
franchises, licenses, sales and payrolls) which have become due pursuant to such
returns or pursuant to any assessment, except for any taxes and assessments, the
amount, applicability or validity of which is currently being contested in good
faith by appropriate proceedings and with respect to which OSMC has set aside on
its books adequate reserves. There are no tax liens on any of OSMC's assets
except those with respect to taxes not yet due and payable. There are no pending
tax examinations of OSMC's tax returns nor has OSMC received a revenue agent's
report asserting a tax deficiency in the last twelve (12) months. There are not
and will not be at the Closing Date, any claims pending or asserted against OSMC
for unpaid taxes by any federal, state or other governmental body. OSMC has
withheld from each payment made to employees of OSMC the amount of all taxes
(including, but not limited to, federal, state and local income taxes and
Federal Insurance Contribution Act taxes) required to be withheld therefrom and
all amounts customarily withheld therefrom, and has set aside all other employee
contributions or payments customarily set aside with respect to such wages and
has paid or will pay the same to, or has deposited or will deposit such payment
with, the proper tax receiving officers or other appropriate authorities.

         (p)  Employee Benefit Plans.

                  (i) List of Plans. Section 3(p) of the Disclosure Schedule
         contains an accurate and complete list of all employee benefit plans
         ("Employee Benefit Plans") within the meaning of Section 3(3) of the
         Employee Retirement Income Security Act of 1974, as amended ("ERISA"),
         whether or not any Employee Benefit Plans are otherwise exempt from the
         provisions of ERISA, established, maintained or contributed to by OSMC
         (including all employers (whether or not incorporated) which by reason
         of common control are treated together with OSMC and/or the OSMC
         Stockholders as a single employer within the meaning of Section 414 of
         the Code) since September 2, 1974.

                  (ii) Status of Plans. OSMC has never maintained and does not
         now maintain or contribute to any Employee Benefit Plan subject to
         ERISA which is not in substantial compliance with ERISA, or which has
         incurred any accumulated funding deficiency within the meaning of
         Section 412 or 418B of the Code, or which has applied for or obtained a
         waiver from the Internal Revenue Service of any minimum funding
         requirement under Section 412 of the Code or which is subject to Title
         IV of ERISA. OSMC has not incurred any liability to the Pension Benefit
         Guaranty Corporation ("PBGC") in connection with any Employee Benefit
         Plan covering any employees of OSMC or ceased operations at any
         facility or withdrawn from any such Plan in a manner which could
         subject it to liability under Section 4062(f), 4063 or 4064 of ERISA,
         and knows of no facts or circumstances which might give rise to any
         liability of OSMC to the PBGC under Title IV of ERISA which could
         reasonably be anticipated to result in any claims being made against
         OSMC by the PBGC. OSMC has not incurred any withdrawal liability
         (including any contingent or secondary withdrawal liability) within the
         meaning of Sections 4201 and 4202 of ERISA, to any Employee Benefit
         Plan which is a Multiemployer Plan (as defined in Section 4001 of
         ERISA), and no event has occurred, and there exists no condition or set
         of circumstances, which represent a material risk of the occurrence of
         any withdrawal from or the partition, termination, reorganization or
         insolvency of any Multiemployer Plan which would result in any
         liability of OSMC.

                  (iii) Contributions. Full payment has been made of all amounts
         which OSMC is required, under applicable law or under any Employee
         Benefit Plan or any agreement relating to any Employee Benefit Plan to
         which OSMC is a party, to have paid as contributions thereto as of the
         last day of the most recent plan year of such Employee Benefit Plan
         ended prior to the date hereof. OSMC has made adequate provision for
         reserves to meet contributions that have not been made because they are
         not yet due under the terms of any Employee Benefit Plan or related
         agreements. Benefits under all Employee Benefit Plans are as
         represented and have not been increased subsequent to the date as of
         which documents have been provided.

                  (iv) Tax Qualification. Each Employee Benefit Plan intended to
         be qualified under Section 401(a) of the Code has been determined to be
         so qualified by the Internal Revenue Service and nothing has occurred
         since the date of the last such determination which resulted or is
         likely to result in the revocation of such determination.

                  (v) Transactions. OSMC has not engaged in any transaction with
         respect to the Employee Benefit Plans which would subject it to a
         material tax, penalty or liability for prohibited transactions under
         ERISA or the Code nor have any of its directors, officers or employees
         to the extent they or any of them are fiduciaries with respect to such
         plans, breached any of their responsibilities or obligations imposed
         upon fiduciaries under Title I of ERISA which would result in any
         material claim being made under or by or on behalf of any such plans by
         any party with standing to make such claim.

                  (vi) Other Plans. OSMC presently does not maintain any
         Employee Benefit Plans or any other foreign pension, welfare or
         retirement benefit plans other than those listed on Section 3(p) of the
         Disclosure Schedule.

                  (vii) Documents. OSMC has delivered or caused to be delivered
         to SCN true and complete copies of (i) all Employee Benefit Plans as in
         effect, together with all amendments thereto which will become
         effective at a later date, as well as the latest IRS determination
         letter obtained with respect to any such Employee Benefit Plan
         qualified under Section 401 or 501 of the Code, and (ii) the most
         recently filed Form 5500 for each Employee Benefit Plan required to
         file such form.

         (q) Third-Party Relations. OSMC has not received any notice that any
material patient, supplier, employee or associated physician intends to cease
doing business with OSMC.

         (r) Compliance with Applicable Laws. OSMC has operated in compliance
with all federal, state, county and municipal laws, constitutions, ordinances,
statutes, rules, regulations and orders applicable thereto ("Applicable Laws").
No item disclosed in Section 3(r) of the Disclosure Schedule could have a
material effect on SCN. Neither OSMC nor any physician associated with or
employed by OSMC 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. ss. 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 government agency.

         (s) Employee Compensation. OSMC has paid or discharged or will pay or
discharge or assume all liabilities for compensation and benefits to which all
employees, including physician employees, are entitled through the Closing Date,
including but not limited to all salaries, wages, bonuses, incentive
compensation, payroll taxes, hospitalization and medical expenses, deferred
compensation, and vacation and sick pay, as well as any severance pay becoming

         other material defined, regulated controlled or potentially subject to
         any remediation requirement under any Environmental Law (collectively
         "Hazardous Materials"), on, in, under or affecting any property owned
         or leased by OSMC.

                  (iii) OSMC has, and is in compliance with, all licenses,
         permits, registrations, and government authorizations necessary to
         operate under all applicable Environmental Laws. Section 3(t) of the

         government authorizations required by any Environmental Law.

                  (iv) OSMC has not received any written or oral notice from any

                  (v) With respect to the generation, transportation, treatment,
         storage and disposal or other handling of Medical Waste, OSMC has
         complied with all Medical Waste Laws.

         (u) Healthcare Compliance. OSMC is participating in or otherwise
authorized to receive reimbursement from Medicare and Medicaid and is a party to
other third-party payor agreements if any, discussed in Section 3(i) of the
Disclosure Schedule. 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, 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. OSMC is in
compliance in all material respects with the requirements of all such
third-party payors. OSMC, the OSMC Stockholders, and OSMC's physician employees
do not have any financial relationship (whether investment interest,
compensation interest, or otherwise) with any entity to which any of the
foregoing refer patients, except for such financial relationships that qualify
for exceptions to state and federal laws restricting physician referrals to
entities in which they have a financial interest.

         (v) Fraud and Abuse. OSMC, the OSMC Stockholders and persons and
entities providing professional services for OSMC have not engaged in any
activities which are prohibited under 42 U.S.C. ss. 1320a-7b, or the regulations
promulgated thereunder pursuant to such statutes, or related state or local
statutes or regulations, or which are prohibited by rules of professional
conduct, including the following: (a) 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; (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 its 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 (1) 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 (2) 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.

         (w) Practice Compliance. OSMC is duly licensed as a medical practice
and is lawfully operated in accordance with the requirements of all Applicable
Laws and has all necessary authorizations for the use and operation of a medical
practice, all of which are in full force and effect. There are no outstanding
notices of deficiencies relating to OSMC issued by any governmental authority or
third-party payor requiring conformity or compliance with any applicable law or
condition for participation with such governmental authority or third-party
payor, and after reasonable and independent inquiry and due diligence and
investigation, OSMC 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 of Business.

         (x) Rates and Reimbursement Policies. The jurisdiction in which OSMC is
located does not currently impose any restrictions or limitations on rates which
may be charged to private pay patients receiving services provided by OSMC. OSMC
does not have any rate appeal currently pending before any governmental
authority or any administrator of any third-party payor program. No Applicable
Law which affects rates or reimbursement procedures has been enacted,
promulgated or issued within the eighteen (18) months preceding the date of this
Agreement and no such legal requirement is proposed or currently pending in the
jurisdiction in which OSMC is located, which could have a material adverse
effect on OSMC or may result in the imposition of additional Medicaid, Medicare,
charity, free care, welfare, or other discounted or government assisted patients
at OSMC or require OSMC to obtain any necessary authorization which OSMC does
not currently possess.

         (y) Accounts Receivable. All accounts receivable, unbilled invoices and
other debts due or recorded in the respective records and books of account of
OSMC, as being due to OSMC, have arisen in the Ordinary Course of Business; and
none of such accounts receivable or other debts is or will at the Closing Date
be subject to any counterclaim or set-off except to the extent of any such
provision or reserve. There has been no material adverse change since December
31, 1996,


                                     - 12 -

in the amount of accounts receivable or other debts due OSMC, the allowances
with respect thereto, or accounts payable of OSMC from that reflected in the
Balance Sheet previously delivered by OSMC to SCN.

         (z) Guaranties. OSMC is not a guarantor and otherwise is not liable for
any liability or obligation (including indebtedness) of any other Person.

         (aa) Powers of Attorney. There are no outstanding powers of attorney
executed by OSMC, except as may be contained in financing documents or security
agreements listed in Section 3(i) of the Disclosure Schedule.

         (bb) Tangible Assets. OSMC owns or leases all land, buildings,
machinery, equipment, and other tangible assets necessary for the conduct of its
business as presently conducted. Each tangible asset is free from defects, has
been maintained in accordance with normal industry practice, and is in good
operating condition and repair (subject to normal wear and tear).

         (cc)  SCN Share Ownership; Investment Intent.

                  (i) Neither OSMC nor the OSMC Stockholders owns, beneficially
         or otherwise, any SCN Shares.

                  (ii) SCN Shares issuable in the Merger are being acquired by
         the OSMC Stockholders solely for their own account for investment and
         not with a view to the distribution thereof, and the OSMC Stockholders
         acknowledge and understand that the certificate(s) representing such
         SCN Shares will bear a legend in substantially the following form:

                  THE SHARES OF STOCK REPRESENTED BY THIS CERTIFICATE HAVE NOT
                  BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED,
                  OR UNDER ANY STATE SECURITIES ACT AND CANNOT BE SOLD,
                  TRANSFERRED, OR OTHERWISE DISPOSED OF UNLESS REGISTERED UNDER
                  SUCH ACTS OR UNLESS EXEMPTIONS FROM REGISTRATION ARE
                  AVAILABLE.

                  (iii)  The OSMC Stockholders represent and warrant as follows:

                           (A) Each OSMC Stockholder is an "accredited investor"
                  as defined under Rule 501 of Regulation D promulgated under
                  the Securities Act.

                           (B) The OSMC Stockholders confirm that SCN has made
                  available to them or to their representatives the opportunity
                  to ask questions of SCN officers and directors and to acquire
                  such information about the SCN Shares and the business and
                  financial condition of SCN as the OSMC Stockholders requested,
                  which additional information has been received.

                           (C) In deciding to acquire SCN Shares pursuant to
                  this Agreement, the OSMC Stockholders consulted with their
                  legal, financial, and tax advisors with respect to the Merger
                  and the nature of the investment together with any additional
                  information provided under subsection (B) above.

                           (D) Each OSMC Stockholder has adequate means of
                  providing for his current needs and personal contingencies and
                  has no need for liquidity in his investment in SCN. Each OSMC
                  Stockholder, either alone or with his representatives, has
                  such knowledge and experience in financial and business
                  matters that they are capable of evaluating the merits and
                  risks of the Merger.

                           (E) The OSMC Stockholders understand and acknowledge
                  that the investment in the SCN Shares is a speculative
                  investment which involves a high degree risk of loss of such
                  OSMC Stockholders'


 
 

                                     - 13 -

                  investment therein; that there are substantial restrictions on
                  the transferability of the SCN Shares under the terms of the
                  Service Agreement and the applicable provisions of the
                  Securities Act and the rules and regulations promulgated
                  thereunder and applicable state securities or "blue sky" laws;
                  and, accordingly, that it may not be possible to liquidate an
                  investment in the SCN Shares.

                           (F) The OSMC Stockholders have been advised and
                  understand that (i) the offer and sale of the SCN Shares have
                  not been registered under the Securities Act; (ii) the SCN
                  Shares must held indefinitely and the OSMC Stockholders must
                  continue to bear the economic risk of the investment in the
                  SCN Shares until the offer or sale of the SCN Shares is
                  subsequently registered under the Securities Act or any "blue
                  sky" laws or an exemption from such registration is available;
                  (iii) Rule 144 promulgated under the Securities Act is not
                  presently available with respect to the sale of any securities
                  of SCN, including the SCN Shares, and when and if the SCN
                  Shares may be disposed of without registration in reliance on
                  Rule 144, such disposition can be made only in accordance with
                  the terms and conditions of such Rule; (iv) the restrictive
                  legends described in Section 3(cc)(ii) shall be placed on the
                  certificates representing the SCN Shares; and (v) a notation
                  shall be made in the appropriate records of SCN indicating
                  that the SCN Shares are subject to restrictions on transfer
                  and appropriate stop-transfer instructions will be issued to
                  any transfer agent with respect to the SCN Shares.

         (dd) Full Disclosure. No representation or warranty made by OSMC in
this Agreement contains or will contain any untrue statement of a material fact
or omits or will omit to state a material fact necessary to make the statements
contained herein or therein not misleading.

         4. Representations and Warranties of SCN. SCN represents and warrants
to OSMC that the statements contained in this Section 4 are correct and complete

14,662,575 SCN Shares are issued and outstanding and 2,000,000 shares of
preferred stock, none of which are issued and outstanding. All of the SCN Shares
to be issued in the Merger have been duly authorized and, upon consummation of
the Merger, will be validly issued, fully paid, and nonassessable.

         (c) Authorization of Transaction. SCN has full power and authority
(including full corporate power and authority) to execute and deliver this
Agreement, to issue the SCN Shares and otherwise to perform its obligations
hereunder; provided, however, that SCN cannot consummate the transaction unless
and until the Merger receives the approval of the SCN Board of Directors. Except

                  (i) the Parties may terminate this Agreement by mutual written
         consent at any time prior to the Effective Time;

                  (ii) SCN may terminate this Agreement by giving written notice
         to OSMC at any time prior to the Effective Time (A) in the event OSMC
         has breached any representation, warranty, or covenant contained in
         this


 
 

                                     - 19 -

<PAGE>



         Agreement in any material respect, SCN has notified OSMC of the breach,
         and the breach has continued without cure for a period of 30 days after
         the notice of breach, (B) if the Closing shall not have occurred on or
         before June 30, 1997 by reason of the failure of any condition
         precedent under Section 6(a) hereof (unless the failure results
         primarily from SCN breaching any representation, warranty, or covenant
         contained in this Agreement) or (C) in accordance with Section 5(j); or

                  (iii) OSMC may terminate this Agreement by giving written
         notice to SCN at any time prior to the Effective Time (A) in the event
         SCN has breached any representation, warranty, or covenant contained in
         this Agreement in any material respect, OSMC has notified SCN of the
         breach, and the breach has continued without cure for a period of 30
         days after the notice of breach or (B) if the Closing shall not have
         occurred on or before June 30, 1997 by reason of the failure of any
         condition precedent under Section 6(b) hereof (unless the failure
         results primarily from OSMC breaching any representation, warranty, or
         covenant contained in this Agreement).

         (b) Effect of Termination. If any Party terminates this Agreement
pursuant to Section 8(a) 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 Merger is not consummated (i) due to the fault of
OSMC or the OSMC Stockholders, or (ii) because SCN is dissatisfied with any
disclosure made in the Disclosure Schedule, then OSMC agrees to reimburse SCN
for SCN's out of pocket expenses, including but not limited to professional
fees, related to the proposed transaction.

         9.  Indemnification.

         (a) Indemnification by the OSMC Stockholders. The OSMC Stockholders,
jointly and severally, agree to and shall defend, indemnify and hold harmless
SCN, its successors and assigns, officers and directors against any and all
losses, liabilities, expenses (including, but without limitation, reasonable
attorneys fees) and damages resulting from or arising out of the breach, untruth
or inaccuracy of any representation, warranty or covenant of OSMC or the OSMC
Stockholders set forth in this Agreement or from any loss, liability or expense
resulting from or related to OSMC's operation of its business prior to the
Effective Time. The OSMC Stockholders shall not be liable to SCN for any claims
against the OSMC Stockholders under this Section 9(a) unless and until the
aggregate of all claims against the OSMC Stockholders exceeds the sum of
$25,000.00, whereupon SCN shall be entitled to recover the full amount of all
claims, including the initial $25,000.00.

         (b) Notice to the OSMC Stockholders; Opportunity to Defend. SCN agrees
to give prompt notice to the OSMC Stockholders of the assertion of any claim, or
the commencement of any suit, action or proceeding, in respect of which
indemnity may be sought under Section 9(a). The OSMC Stockholders may
participate in and at their election, or at the request of SCN, assume the
defense of any such suit, action or proceeding at the OSMC Stockholders'
expense. The OSMC Stockholders shall not be liable under Section 9(a) for any
settlement effected without their consent of any claim, litigation or proceeding
in respect of which indemnity may be sought under Section 9(a), which consent
shall not be unreasonably withheld.

         (c) General Indemnification by SCN. SCN agrees to and shall defend,
indemnify and hold harmless the OSMC Stockholders, their heirs and assigns
against any and all losses, liabilities, expenses (including, but without
limitation, reasonable attorneys fees) and damages resulting from the breach,
untruth or inaccuracy of any representation, warranty or covenant of SCN set
forth in this Agreement. SCN shall not be liable to the OSMC Stockholders for
any claims against SCN under this Section 9(c) unless and until the aggregate of
all claims against SCN exceeds the sum of $25,000.00, whereupon the OSMC
Stockholders shall be entitled to recover the full amount of all claims,
including the initial $25,000.00.

         (d) Notice to SCN; Opportunity to Defend. The OSMC Stockholders agree
to give prompt notice to SCN of the assertion of any claim, or the commencement
of any suit, action or proceeding in respect of which indemnity may be sought
under Section 9(c). SCN may participate in and, at its election, or at the
request of the OSMC Stockholders, assume the


 
 

                                     - 20 -

<PAGE>



defense of any such suit, action or proceeding at SCN's expense. SCN shall not
be liable under Section 9(c) 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.

         (e) Right of Setoff. In the event of any breach of warranty,
representation, covenant or agreement by OSMC or the OSMC Stockholders giving
rise to indemnification to SCN under Section 9(a) hereof, SCN shall be entitled
to offset the amount of damages incurred by it as a result of such breach of
warranty, representation, covenant or agreement against (1) the amounts payable
to the OSMC Stockholders or The Orthopaedic and Sports Medicine Center II, P.A.
under the Service Agreement; (2) any amount payable to the OSMC Stockholders
pursuant to any convertible debenture comprising part of the Merger
Consideration or Contingent Merger Consideration; or (3) the Contingent Merger
Consideration. In the event that SCN determines that an amount is to be so
offset, as a condition precedent to such right of offset, SCN shall give the
OSMC Stockholders written notice of the amount of such proposed offset and the
basis therefor within thirty (30) days after the date on which such amount is
finally determined. If SCN shall not have received written notice from the OSMC
Stockholders contesting such offset within twenty (20) days of their receipt of
such written notice from SCN, the offset shall be deemed to have been consented
to by the OSMC Stockholders, and SCN shall be entitled to deduct the entire
amount claimed as an offset from the next succeeding amounts payable under the
Service Agreement. In the event that the OSMC Stockholders shall object to the
proposed offset by written notice received by SCN during such twenty (20) day
period, the entitlement of SCN to the claimed offset shall be determined as set
forth in Section 10.4.3 and Section 10.4.4 of the Service Agreement.

         10.  Miscellaneous.

         (a) Survival. The representations and warranties of the OSMC
Stockholders, OSMC and SCN contained in this Agreement and the indemnifications
contained herein shall survive the Closing. No claim for indemnification with
respect to any alleged misrepresentation or breach of warranty or covenant may
be made after three (3) years following the Closing Date. Any matter to which
indemnification pertains and with respect to which a claim has been asserted or
threatened following the Closing Date shall continue to be subject to the
indemnification under this Agreement until finally terminated, settled, resolved
or adjudicated; and all terms, conditions and stipulations of this Agreement
shall likewise continue to apply.

         (b) No Third-Party Beneficiaries. Except as provided in Section 9(e),
this Agreement shall not confer any rights or remedies upon any Person other
than the parties and their respective successors and permitted assigns.

         (c) Entire Agreement. This Agreement (including the Agreement and Plan
of Merger and other 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.

         (d) 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 Party.

         (e) 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.

         (f) Headings. The section headings contained in this Agreement are
inserted for convenience only and shall not affect in any way the meaning or
interpretation of this Agreement.

         (g) Notices. All notices, requests, demands, claims, and other

construed in accordance with the domestic laws of the State of Delaware without
giving effect to any choice or conflict of law provision or rule (whether of the
State of Delaware or any other jurisdiction) that would cause the application of
the laws of any jurisdiction other than the State of Delaware. Each of the

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

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,

any default, misrepresentation, or breach of warranty or covenant hereunder,
whether intentional or not, shall be deemed to extend to any prior or subsequent

affect in any way any rights arising by virtue of any prior or subsequent such
occurrence.

         (j) 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.

         (k) 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.

         (l) 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.

         (m) 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 OSMC
Articles of Merger 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.

         9.  Capital Stock.  At the Effective Time:

                  (a) At and as of the Effective Time, each of the issued and
         outstanding OSMC Shares shall be converted into the right to receive
         4,115.910751 SCN Shares (the "Conversion Ratio"). The Conversion Ratio
         shall be subject to equitable adjustment in the event of any stock
         split, stock dividend, reverse stock split, or other change in the

         Election") to convert, at and as of the Effective Time, and, upon such
         election, each OSMC Share owned by him shall be converted into the
         right to receive (A) a number of SCN Shares equal to the Conversion
         Ratio times a percentage between 50% and 100% ("Stock Percentage")
         multiplied by the number of OSMC Shares owned by him, plus (B) a cash
         payment per OSMC Share ("Cash Consideration"), or, in the alternative,
         an SCN subordinated unsecured convertible debenture (a "Debenture" the
         form of which is set forth as Exhibit 2(d)(v)(1) to the Merger
         Agreement), or any combination thereof, per OSMC Share equal to the
         Conversion Ratio times the reciprocal of the Stock Percentage times the
         Average SCN Price. In the alternative, each OSMC Stockholder may elect
         (a "Cash/Warrant Election") to convert, at and as of the Effective
         Time, and,


 
 

                                   Exhibit 1-2

<PAGE>



         upon such election, each OSMC Share owned by him shall be converted
         into the right to receive (1) a number of SCN Shares equal to the
         Conversion Ratio times a Stock Percentage multiplied by the number of
         OSMC Shares owned by him, plus (2) Cash Consideration per OSMC Share
         equal to the Conversion Ratio, times a percentage between 0% and 25%
         ("Cash/Warrant Percentage"), times 90% of the Average SCN Price, plus
         (3) a warrant (a "Warrant", the form of which is set forth as Exhibit
         2(d)(v)(2) to the Merger Agreement) to purchase .08114 SCN Shares per
         dollar of Cash Consideration determined pursuant to clause (2) above,
         plus (4) additional Cash Consideration or Debentures ("Residual
         Consideration"), or any combination thereof, equal to the Conversion
         Ratio times the Average SCN Stock Price times 100% minus the sum of the
         Stock Percentage and Cash Option Percentage elected by the OSMC
         Stockholder. A Cash/Debt Election or Cash/Warrant Election shall be
         made in writing (the "Election Notice") delivered to SCN by the
         electing OSMC Stockholder no later than 2:00 p.m. Central Standard Time
         on March 27, 1997. The Cash/Debt Election shall be submitted on the
         form attached as Exhibit 2(d)(v)(3) to the Merger Agreement, and the
         Cash/Warrant Election shall be submitted on the form attached as
         Exhibit 2(d)(v)(4) to the Merger Agreement. At Closing, SCN shall cause
         to be issued and/or delivered to the OSMC Stockholders certificates
         representing the SCN Shares to be issued in the Merger, as finally
         determined, together with the Cash Consideration, Debentures and
         Warrants, as applicable, into which the OSMC Shares shall have been
         converted at the Effective Time. The foregoing SCN Shares and, if
         elected, Cash Consideration, Debentures and Warrants deliverable to the
         OSMC Stockholders in the Merger is sometimes herein referred to as the
         "Merger Consideration."

                  In addition to the Merger Consideration, if the Hospital JV is
         formed and becomes operational on or before May 15, 1997, the OSMC
         Stockholders shall be entitled to receive the Contingent Merger
         Consideration. The Contingent Merger Consideration shall be payable in
         the same percentages of SCN Shares, cash and convertible debentures as
         the OSMC Stockholders shall have elected pursuant to Section 2(d)(v) of
         the Merger Agreement. The parties shall, at Closing, execute and
         deliver the Escrow Agreement and shall deliver to the Escrow Agent a
         combination of SCN Shares, cash and/or convertible debentures equal to,
         in the aggregate, the Parties' best estimate, determined as of the
         Closing Date, of the Contingent Merger Consideration. For this purpose,
         the number of SCN Shares shall be determined based on a price per SCN
         Share of $9.86. On the Escrow Release Date, the amount of Contingent
         Merger Consideration shall be determined by the parties based on the
         definitive agreement for the Hospital JV. On the Escrow Release Date,
         the Escrow Agent shall deliver to the OSMC Stockholders the escrowed
         consideration (with SCN Shares being valued at the price set forth in
         the second preceding sentence) up to, but not in excess of, the
         Contingent Merger Consideration, with any remaining escrowed
         consideration being returned to SCN, all pursuant to the Escrow
         Agreement.

                  (b) On and after the Effective Date, the holders of OSMC
         Common Stock shall cease to have any rights as stockholders of OSMC
         except for the right to surrender their stock in exchange for payment
         of the merger consideration.

                  (c) Each share of Common Stock of SCN issued and outstanding
         immediately prior to the Effective Time shall remain issued and
         outstanding.

         10. No Fractional Shares. No fractional shares of SCN Common Stock
shall be issued pursuant to the Merger. In lieu of the issuance of any such
fractional shares of SCN Common Stock, cash adjustments will be paid to holders
in respect of any fractional shares of SCN Common Stock that would otherwise be
issuable. The amount of such adjustment shall be the product of such fraction of
a share of SCN Common Stock multiplied by $9.86.

         11. Amendment or Termination. Notwithstanding stockholder approval of
this Agreement and Plan of Merger, this Agreement and Plan of Merger may be
amended or terminated at any time on or before the Effective Date by agreement
of the Boards of Directors of the Constituent Corporations, provided that no
amendment may be made which decreases the Conversion Ratio.
