Corporation shall, without any other action, possess all the rights,
privileges, powers and franchises of a public as well as of a private nature,

reason of the Merger; but all rights of creditors and all liens upon any
property of either of the Constituent Corporations shall be preserved
unimpaired, and all debts, liabilities and duties of either of the Constituent
Corporations shall thenceforth attach to the Surviving Corporation, and may be
enforced against it to the same extent as if said debts, liabilities and duties
had been incurred or contracted by it.

         1.3     Effective Time and Transaction Effective Date.  The Merger
shall become effective at the time of the filing of the Certificate of Merger
with the office of the Secretary of State of the State of Maryland in

Merger shall be so filed as soon as practicable after the Closing (as defined
in Section 8.1). The date and time when the Merger shall become effective for
the purposes of Maryland law are herein referred to as the "Effective Time";
upon consummation, the Closing shall be deemed to be effective for all other
purposes as of 12:01 a.m. local time on January 1, 1997 (the "Transaction
Effective Date").

         1.4     Articles of Incorporation.  The Articles of Incorporation of

Articles of Incorporation of the Surviving Corporation until amended in
accordance with the provisions of the applicable corporate law, except that at
the Effective Time the Certificate of Incorporation may be amended and restated
as may be provided for in the form of the Certificate of Merger.

         1.5     Bylaws.  The Bylaws of the Capstone Sub in effect immediately

         1.6     Directors.  The directors of the Capstone Sub immediately
prior to the Effective Time shall, after the Effective Time, be the directors
of the Surviving Corporation without change, until their successors have been
duly elected and qualified in accordance with the Certificate of Incorporation
and Bylaws of the Surviving Corporation.

         1.7     Officers.  The officers of the Capstone Sub immediately prior
to the Effective Time shall, after the Effective Time, be the officers of the

                ARTICLE II.  STATUS AND CONVERSION OF SECURITIES

         2.1     Conversion of Securities.  At the Effective Time, by virtue of
the Merger and without any action on the part of Parent, Capstone Sub, Company
or the Shareholder:

                 (1)      Each share of common stock, par value $.01 per share,

shall continue without change and shall represent validly issued, fully paid
and nonassessable shares of common stock of the Surviving Corporation.

                 (2)      Each share of Company Common Stock held by Company as
a treasury share shall be canceled and no payment shall be made with respect
thereto.

                 (3)      Each outstanding share of Company Common Stock issued

the Merger and without any action on the part of the holder thereof,
automatically be canceled and extinguished and converted into the right to
receive an aliquot portion of the Merger Consideration (as defined below) as

         2.2     Merger Consideration.  The aggregate merger consideration
payable pursuant hereto and to the Related Merger Agreement, subject to
adjustment as described herein and therein, is Forty Million Dollars
($40,000,000.00).  The merger consideration payable by Parent to Shareholder in
consideration for the Merger and for the agreements contained herein, including

value of Thirteen Million Dollars ($13,000,000.00), based upon the average
closing bid price per share of the





                                      3
<PAGE>   9

Capstone Common Stock on the Nasdaq Stock Market for the fifteen (15)
consecutive trading days ending one day prior to the Closing (the "Average
Price"); and

                 (3)      the number of shares of Capstone Common Stock having
an aggregate market value of Two Million Dollars ($2,000,000.00), based upon
the Average Price, to be held in escrow (the "Escrowed Shares"), from which 50%
of such shares then held by the escrow agent will be released on the first
anniversary of the Closing ("First Anniversary Shares") and the remainder of
which will be released on the second anniversary of the Closing ("Second
Anniversary Shares"), pursuant to the terms of an escrow agreement (the "Escrow
Agreement"), the form of which is attached hereto as Exhibit 2.2(3).

         All such shares of Capstone Common Stock described in 2.2(2) and
2.2(3) herein shall be subject to a Registration Rights Agreement between
Parent and Shareholder (as described in Section 6.13 hereof) and shall be
collectively referred to herein as the "Merger Consideration Stock".  Upon
effective registration of the Merger Consideration Stock described in Section
2.2(3) hereof, such shares may be sold by Shareholder and the proceeds of such
sale substituted for such sold shares in escrow, in accordance with the
provisions of the Escrow Agreement.

         2.3     Offset.  The Merger Consideration shall be subject to offset
in the following manner:

                 (1)      The Merger Consideration shall be subject to
repayment (out of the Escrow Account, first, and then from Shareholder as
necessary) subsequent to Closing by, in the event that EBITDA falls below the
EBITDA Target (each as defined in Section 4.29 hereof and such shortfall being
herein referred to as the "EBITDA Shortfall"), an amount equal to the EBITDA
shortfall, multiplied by 6.5 (50% of which reduction is to be reflected in this
transaction and 50% in the Related Transaction) (the parties have agreed based
on information provided to date that EBITDA shortfall is zero); and

                 (2)      Subject to the provisions of Article XIII, the
portion of the Merger Consideration reflected in Section 2.2(3) hereof shall be
offset by:

                          (a)     the full extent of the Receivables Shortfall
         (as defined in paragraph 3.1 herein), if any; and

                          (b)     in the event of any losses, costs, and
         expenses (including reasonable cost of investigation, court costs and
         legal fees actually incurred) and other damages resulting from any
         breach by either Company or Shareholder of any of the covenants,
         obligations, representations or warranties or breach or untruth of any
         representation, warranty, fact or conclusion contained in this
         Agreement (collectively, such damages being the "Breach Damages"), at
         Parent's option, to the full extent of such losses, costs, expenses
         and/or damages.





                                      4
<PAGE>   10



Such claims under this Section 2.3(2) shall first be satisfied out of the First
Anniversary Shares until these are exhausted in full.  To the extent such
claims are not satisfied in full by the First Anniversary Shares, they shall
then be satisfied out of the Second Anniversary Shares.  The number of shares
to be offset shall be determined based upon the dollar amount to be offset
divided by the Average Price. To the extent claims under Section 3.2(2)(b) are
not satisfied in full by the Escrowed Shares, then cash payments shall be made
by the Shareholder in accordance with the indemnification provisions of Article
XIII hereof.  To the extent the escrow account contains cash or assets other
than the Escrowed Shares, any claims shall be satisfied first from the Escrowed
Shares and then from such cash or other assets.


                           ARTICLE III.  RECEIVABLES

         3.1     Collection of Receivables.  After Closing, Surviving
Corporation will proceed to collect the Receivables.  Shareholder shall provide
such assistance in the collection process as Surviving Corporation or Parent
may reasonably request.  If, within 180 days following Closing, Surviving
Corporation has collected less than the amount of the Receivables reflected in
the Interim Financial Statements (as such term is defined in paragraph 4.4(1))
in excess of the reserves also therein set forth (such event being a
"Receivables Shortfall"), (a) the Merger Consideration shall be reduced by the
amount of such shortfall in accordance with Section 2.3 hereof, and (b) any
Receivables subject to a Receivables Shortfall shall be assigned to Shareholder
in the amount of each such Shortfall, provided that such Receivables relate to
facilities which are not ongoing clients of the Business or to private
(non-facility) payors.


                 ARTICLE IV. REPRESENTATIONS AND WARRANTIES OF
                                THE SHAREHOLDER

         As a material inducement to Parent and Capstone Sub to enter into this
Agreement and to consummate the transactions contemplated hereunder,
Shareholder hereby represents and warrants to Parent and Capstone Sub, which
representations and warranties shall be true and correct on the date of
Closing, as follows:

any material respect or omits to state any material fact necessary in order to
make any of the statements herein or therein not misleading in light of the
circumstances in which they were made.

<PAGE>   38



                 (1)      Claims by Non-parties. The indemnified party shall
give written notice within a reasonably prompt period of time to the
indemnifying party of any written claim by a third party which is likely to
give rise to a claim by the indemnified party against the indemnifying party
based on the indemnity agreements contained in this Article, stating the nature
of said claim and the amount thereof, to the extent known. The indemnified
party shall give notice to the indemnifying party that pursuant to the
indemnity, the indemnified party is asserting against the indemnifying party a
claim with respect to a potential loss from the third party claim, and such
notice shall constitute the assertion of a claim for indemnity by the
indemnified party. If, within thirty (30) days after receiving such notice, the
indemnifying party advises the indemnified party that it will provide
indemnification and assume the defense at its expense, then so long as such
defense is being conducted, the indemnified party shall not settle or admit
liability with respect to the claim and shall afford to the indemnifying party
and defending counsel reasonable assistance in defending against the claim. If
the indemnifying party assumes the defense, counsel shall be selected by such
party and if the indemnified party then retains its own counsel, it shall do so
at its own expense. If the indemnified party does not receive a written
objection to the notice from the indemnifying party within thirty (30) days
after the indemnifying party's receipt of such notice, the claim for indemnity
shall be conclusively presumed to have been assented to and approved, and in
such case the indemnified party may control the defense of the matter or case
and, at its sole discretion, settle or admit liability. If within the aforesaid
thirty (30) day period the indemnified party shall have received written
objection to a claim (which written objection shall briefly describe the basis
of the objection to the claim or the amount thereof, all in good faith), then
for a period of ten (10) days after receipt of such objection the parties shall
attempt to settle the dispute as between the indemnified and indemnifying
parties. If they are unable to settle the dispute, the unresolved issue or
issues shall be settled by arbitration in Los Angeles, California in accordance
with the rules and procedures of the American Arbitration Association.

                 (2)      Claims by a Party. The determination of a claim
asserted by a party hereunder (other than as set forth in subparagraph (1)
above) pursuant to this Article shall be made as follows: The indemnified party
shall give written notice within a reasonably prompt period of time to the
indemnifying party of any claim by the indemnified party which has not been
made pursuant to subparagraph (1) above, stating the nature and basis of such
claim and the amount thereof, to the extent known. The claim shall be deemed to
have resulted in a determination in favor of the indemnified party and to have
resulted in a liability of the indemnifying party in an amount equal to the
amount of such claim estimated pursuant to this paragraph if within forty-five
(45) days after the indemnifying party's receipt of the claim the indemnified
party shall not have received written objection to the claim. In such event,
the claim shall be conclusively presumed to have been assented to and approved.
If within the aforesaid forty-five (45) day period the indemnified party shall
have received written objection to a claim (which written objection shall
briefly describe the basis of the objection to the claim or the amount thereof,
all in good faith), then for a period of sixty (60) days after receipt of such
objection the parties shall attempt to settle the disputed claim as between the
indemnified and indemnifying parties. If they are unable to settle the disputed
claim, the unresolved issue or issues shall be settled by arbitration in Los
Angeles, California in accordance with the rules and procedures of the





                                     33

American Arbitration Association.  Notwithstanding the provisions of this
clause (2), the enforcement provisions set forth in paragraph 14.2 will be
available in the event of a breach of paragraph 14.1.

                          (3)     Claims by a Straddle Patient. Any claim by a
patient relating to professional negligence or similar matters involving a
patient served both prior to the Transaction Effective Date and subsequent to
the Transaction Effective Date will be the responsibility of either Parent or
Shareholder in accordance with the following guidelines: (i) if it is a claim
in which the incident giving rise to liability clearly arose prior to the
Transaction Effective Date, Shareholder shall respond to the loss and defense
expenses; (ii) if it is a claim in which the incident giving rise to liability
clearly arose on or after the Transaction Effective Date, Parent shall respond
to the loss and defense expenses; and (iii) in the event that the incident
giving rise to liability as to time is not clear, Shareholder and Parent will
jointly defend the case and each will fully cooperate with the other in such
defense.  Once the case is closed, if Parent and Shareholder cannot agree to
the allocation of both indemnity and expenses, then the matter shall be
submitted to binding arbitration in Los Angeles California in accordance with
the rules and procedures of the American Arbitration Association.
Notwithstanding anything seemingly to the contrary contained herein, no
indemnification shall be made hereunder until agreed to by the parties hereto
or settled in arbitration.

         13.5    Indemnity Period. The representations, warranties and
covenants, and the indemnity obligations related thereto, under this Agreement
shall expire 24 months from the Closing, except for claims under sections 4.13
and 4.28 hereof, which shall expire upon the expiration of the applicable
statute of limitations, and except for claims under sections 4.9 or 4.25
hereof, which shall expire on the earlier of the expiration of the applicable
statute of limitations or 48 months from Closing.  The indemnification
obligations under this Agreement shall not expire as provided herein for a
claim made, but not resolved, within the above periods.

         13.6    Limitation on Claims.  The limitations provided in this
Section 13.6 apply solely to the liability of the Shareholder.  The obligations
of an indemnifying party under this Agreement shall not begin until the
indemnified party incurs one or more liabilities which equal Two Hundred
Thousand and No/100 Dollars ($200,000.00) (the "Basket").  Once the Basket is
reached, the obligations of an indemnifying party under this Agreement shall
apply to all claims of the indemnified party, whether such claims are part of
the Basket or in excess thereof.  In no event shall the obligations of an
indemnifying party and its affiliates under this Agreement exceed Four Million
Dollars ($4,000,000.00) (the "Cap").  Notwithstanding the foregoing, the Basket
and the Cap shall not apply to any payroll or withholding issues related to
Shareholder.

                     ARTICLE XIV. PRESERVATION OF BUSINESS
                          AND NONCOMPETE RESTRICTIONS

         14.1    Covenant Not to Compete. Shareholder hereby covenants and
agrees with Parent that, during the NON- COMPETE PERIOD (as such term is
defined herein) and within the NON-COMPETE AREA (as such term is defined
herein), no Shareholder shall directly or indirectly, (a) acquire, lease,
manage, consult for, serve as agent or subcontractor for, finance, invest in,
own any part of or exercise management control over any health care operation
or business which provides any goods or services competitive with the goods and
services provided by the Business as of the Closing, or (b) solicit for
employment or employ any person who at Closing or thereafter became an employee
of Parent, Surviving Corporation or an affiliate unless such person is not so
employed for at least six (6) months, or (c) with respect to any customer,
patient, physician, physician group, or healthcare provider with whom Parent,
Surviving Corporation and/or an Affiliate contracts with in connection with the
Business, either solicit the same in a manner which could adversely affect
Parent, Surviving Corporation or an Affiliate, or make statements to the same
which disparage Parent, Surviving Corporation, an Affiliate or their respective
operations in any way. The "Non-Compete Period" shall commence at the Closing
and terminate on the third anniversary thereof. The "Non-Compete Area" shall
mean the area within a fifty (50) mile radius of each location from which the
Business or the Related Business is operated or conducted as of the Closing.
Ownership of less than five percent (5%) of the stock of a publicly held
company shall not be deemed a breach of this covenant.

         14.2    Enforceability. In the event of a breach of paragraph 14.1,
Shareholder recognizes that monetary damages shall be inadequate to compensate
Parent and Surviving Corporation, and Parent and Surviving Corporation shall be
entitled, without the posting of a bond or similar security and notwithstanding
the arbitration provisions contained in Article XIII, to an injunction
restraining such breach, with the costs (including attorney's fees) of securing
such injunction to be borne by Shareholder. Nothing contained herein shall be
construed as prohibiting Parent or Surviving Corporation from pursuing any
other remedy available to either for such breach or threatened breach.  All
parties hereby acknowledge the necessity of protection against the competition
of Shareholder and that the nature and scope of such protection has been
carefully considered by the parties. The period provided and the area covered
are expressly represented and agreed to be fair, reasonable and necessary. The
consideration provided for herein is deemed to be sufficient and adequate to
compensate Shareholder for agreeing to the restrictions contained in paragraph
14.1. If, however, any court determines that the forgoing restrictions are not
reasonable, such restrictions shall be modified, rewritten or interpreted to
include as much of their nature and scope as will render them enforceable.

                           ARTICLE XV. MISCELLANEOUS

         15.1    Assignment. Following Closing, Parent and Surviving
Corporation may freely assign any or all of their respective rights or delegate
any or all of their respective obligations under this Agreement without the
express written consent of Shareholder; provided however that Parent shall
remain primarily liable with regard to its obligations hereunder. No
Shareholder may assign any rights or delegate any obligations under this
Agreement without the prior written consent of Parent, and any prohibited
assignment or delegation will be null and void.

         15.2    Other Expenses. Except as otherwise provided in this
Agreement, Shareholder shall pay all of his and Company's expenses in
connection with the negotiation, execution, and implementation of the
transactions contemplated under this Agreement and Parent shall pay all of its
and Capstone Sub's expenses in connection with the negotiation, execution, and
implementation of the transactions contemplated under this Agreement. All sales
and use taxes, recording fees and transfer taxes incurred in connection under
the transactions contemplated within this Agreement shall be prorated as of the
Transaction Effective Date between the Shareholder and Parent respectively,
such that the Shareholder pay all such taxes with respect to the Business up to
the Transaction Effective Date, and the Parent pays all such amounts
thereafter.  Shareholder represents that, with respect to the laws of the State
of California, ad valorem or similar taxes are not applicable to the
transactions contemplated hereunder, and that Shareholder shall indemnify
Surviving Corporation and Parent for any costs incurred from circumstances to
the contrary.

         15.3    Notices. All notices, requests, demands, waivers and other
communications required or permitted to be given under this Agreement shall be
in writing and shall be deemed to have been duly given: (a) if delivered
personally or sent by facsimile, on the date received, (b) if delivered by
overnight courier, on the day after mailing, and (c) if mailed, five days after
mailing with postage prepaid. Any such notice shall be sent as follows:

                 To Shareholder and, prior to Closing, Company:

                 Irving, Texas  75063
                 Attn:  Chief Executive Officer

                 with a copy to:

                 315 Deaderick Street
                 Nashville, Tennessee  37238-1800

         15.4    Confidentiality; Prohibition on Trading. Except for press
releases issued by Parent in the ordinary course following Closing, all parties
agree to maintain the confidentiality of the existence of this Agreement and
the transactions contemplated hereunder, unless disclosure is required by law.
Shareholder, Company and their affiliates agree not to trade in the securities
of Parent or its affiliates based upon any material nonpublic information.

         15.5    Controlling Law. This Agreement shall be construed,
interpreted and enforced in accordance with the laws of the State of Delaware.

         15.6    Headings. Any table of contents and paragraph headings in this
Agreement are for convenience of reference only and shall not be considered or
referred to in resolving questions of interpretation.

         15.7    Benefit. Subject to paragraph 15.1, this Agreement shall be
binding upon and shall inure to the exclusive benefit of the parties hereto and
their respective heirs, legal representatives, successors and assigns. This
Agreement is not intended to, nor shall it, create any rights in any other
party.

         15.8    Partial Invalidity. The invalidity or unenforceability of any
particular provision of this Agreement shall not affect the other provisions
hereof, and this Agreement shall be construed in all respects as if such
invalid or unenforceable provisions were omitted. Further, there shall be
automatically substituted for such invalid or unenforceable provision a
provision as similar as possible which is valid and enforceable.

         15.9    Waiver. Neither the failure nor any delay on the part of any
party hereto in exercising any rights, power or remedy hereunder shall operate
as a waiver thereof, or of any other right, power or remedy; nor shall any
single or partial exercise of any right, power or remedy preclude any further
or other exercise thereof, or the exercise of any other right, power or remedy.
No waiver of any of the provisions of this Agreement shall be void unless it is
in writing and signed by the party against which it is sought to be enforced.

         15.10   Counterparts. This Agreement may be executed simultaneously in
two or more counterparts each of which shall be deemed an original and all of
which together shall constitute but one and the same instrument.

         15.11   Interpretation; Knowledge. All pronouns and any variation
thereof shall be deemed to refer to the masculine, feminine, neuter, singular
or plural as the identity of the person or entity, or the context, may require.
Further, it is acknowledged by the parties that this Agreement has undergone
several drafts with the negotiated suggestions of both; and, therefore, no
presumptions shall arise favoring either party by virtue of the authorship of
any of its provisions or the changes made through revisions. Whenever in this
Agreement the term "to the knowledge of Company or Shareholder" or the like is
used, Company and Shareholder shall be deemed to have the knowledge of those
persons listed on Exhibit 15.11 who are all of the officers of the Company.

         15.12   Entire Agreement. This Agreement, including the Exhibits and
Attachments hereto, constitutes the entire agreement between the parties hereto
with regard to the matters contained herein and it is understood and agreed
that all previous undertakings, negotiations, letter of intent and agreements
between the parties are merged herein. This Agreement may not be modified
orally, but only by an agreement in writing signed by Parent, Company and
Shareholder.

         15.13   Further Assurance of Shareholder After Closing. Subsequent to
the Closing, each of Shareholder and Parent shall from time to time, at the
other's request, execute and deliver such other instruments of conveyance and
transfer, and take such other action as the other may request, in order to
effectuate fully the Merger and vest in Parent and Surviving Corporation (as
the case may be), on the one hand, and Shareholder, on the other the benefits
of the Merger as contemplated hereunder.

         15.14   Legal Fees and Costs. In the event any party hereto incurs
legal expenses to enforce or interpret any provision of this Agreement, the
prevailing party will be entitled to recover such legal expenses, including,
without limitation, attorney's fees, costs and disbursements, in addition to
any other relief to which such party shall be entitled.

<PAGE>   9

Capstone Common Stock on the Nasdaq Stock Market for the fifteen (15)
consecutive trading days ending one day prior to the Closing (the "Average
Price"); and

                 (3)      the number of shares of Capstone Common Stock having
an aggregate market value of Two Million Dollars ($2,000,000.00), based upon
the Average Price, to be held in escrow (the "Escrowed Shares"), from which 50%
of such shares then held by the escrow agent will be released on the first
anniversary of the Closing ("First Anniversary Shares") and the remainder of
which will be released on the second anniversary of the Closing ("Second
Anniversary Shares"), pursuant to the terms of an escrow agreement (the "Escrow
Agreement"), the form of which is attached hereto as Exhibit 2.2(3).

         All such shares of Capstone Common Stock described in 2.2(2) and
2.2(3) herein shall be subject to a Registration Rights Agreement between
Parent and Shareholders (as described in Section 6.13 hereof) and shall be
collectively referred to herein as the "Merger Consideration Stock."  Upon
effective registration of the Merger Consideration Stock described in Section
2.2(3) hereof, such shares may be sold by Shareholders and the proceeds of such
sale substituted for such sold shares in escrow, in accordance with the
provisions of the Escrow Agreement.

         2.3     Offset.  The Merger Consideration shall be subject to offset
in the following manner:

                 (1)      The Merger Consideration shall be subject to
repayment (out of the Escrow Account, first, and then from Shareholders as
necessary) subsequent to Closing by, in the event that EBITDA falls below the
EBITDA Target (each as defined in Section 4.29 hereof and such shortfall being
herein referred to as the "EBITDA Shortfall"), an amount equal to the EBITDA
shortfall, multiplied by 6.5 (50% of which reduction is to be reflected in this
transaction and 50% in the Related Transaction) (the parties have agreed based
on information provided to date that the EBITA Shortfall is zero); and

                 (2)      Subject to the provisions of Article XIII the portion
of the Merger Consideration reflected in Section 2.2(3) hereof,  shall be
offset by:

                          (a)     the full extent of the Receivables Shortfall
         (as defined in paragraph 3.1 hereof), if any; and

                          (b)     in the event of any losses, costs, and
         expenses (including reasonable cost of investigation, court costs and
         legal fees actually incurred) and other damages resulting from any
         breach by either Company or Shareholders of any of the covenants,
         obligations, representations or warranties or breach or untruth of any
         representation, warranty, fact or conclusion contained in this
         Agreement (collectively, the "Breach Damages"), at Parent's option, to
         the full extent of such losses, costs, expenses and/or damages.

Such claims under this Section 2.3(2) shall first be satisfied out of the First
Anniversary Shares until these are exhausted in full.  To the extent such
claims are not satisfied in full





                                      4
<PAGE>   10

by the First Anniversary Shares, they shall then be satisfied out of the Second
Anniversary Shares.  The number of shares to be offset shall be determined
based upon the dollar amount to be offset divided by the Average Price. To the
extent claims under Section 3.2(2)(b) are not satisfied in full by the Escrowed
Shares, then cash payments shall be made by the Shareholders in accordance with
the indemnification provisions of Article XIII hereof.  To the extent the
escrow account contains cash or assets other than the Escrowed Shares, any
claims shall be satisfied first from the Escrowed Shares and then from such
cash or other assets.


                           ARTICLE III.  RECEIVABLES

         3.1     Collection of Receivables.  After Closing, Surviving
Corporation will proceed to collect the Receivables.  Shareholders shall
provide such assistance in the collection process as Surviving Corporation or
Parent may reasonably request.  If, within 180 days following Closing,
Surviving Corporation has collected less than the amount of the Receivables
reflected in the Interim Financial Statements (as such term is defined in
paragraph 4.4(1)) in excess of the reserves also therein set forth (such event
being a "Receivables Shortfall"), (a) the Merger Consideration shall be reduced
by the amount of such shortfall in accordance with Section 2.3 hereof, and (b)
any Receivables subject to a Receivables Shortfall shall be assigned to
Shareholders in the amount of each such shortfall, provided that such
Receivables relate to facilities which are not ongoing clients of the Business
or to private (non-facility) payors.

warranties of Parent, Company and Shareholders contained in this Agreement, or
in any certificate or document delivered pursuant to this Agreement, shall be
deemed to be material and to have been relied upon by the parties hereto
notwithstanding any investigation prior to the Closing, shall survive the date
of Closing as provided in section 13.5 hereof, and shall not be merged into any
documents delivered in connection with the Closing.

         13.2    Indemnification by Shareholders. Subject to the provisions of
paragraph 13.4, Shareholders shall jointly and severally promptly indemnify,
defend, and hold harmless Parent, Surviving Corporation and the directors,

<PAGE>   37

agents of each against any and all losses, costs, and expenses (including
reasonable cost of investigation, court costs and legal fees actually incurred)
and other damages resulting from (i) any breach by either Company or
Shareholders of any of their covenants, obligations, representations or
warranties or untruth of any representation or warranty contained in this
Agreement (payment for which is to be initially made pursuant to the offset
provisions of Section 2.3 hereof) or any certificate or closing document of
Company and/or Shareholders required to be delivered pursuant to this Agreement
(which Closing Documents are the following:  Employment Agreement, Assumption
Agreement, Escrow Agreement, Lease, Registration Rights Agreement, Letter
Agreement, (ii) any liability of Company not expressly retained by Surviving
Corporation or assumed by Parent pursuant to Paragraph 4.11(4) hereof, and
(iii) except as related to the Continuing Liabilities, any claim (whether or
not disclosed herein) that is brought or asserted by any third party(s) against
Parent or Surviving Corporation arising out of the ownership, licensing,
operation or conduct of the Business or Assets or the conduct of any of
Company's employees, agents or independent contractors, relating to all periods
of time prior to the Transaction Effective Date. Any indemnification payment
made pursuant to this Article shall include interest at a floating rate equal
to two points over the prime rate of Bankers Trust Company established from
time to time (the "Rate") payable for the period measured from the date that
the loss, cost, expense or damage was incurred until the date of payment.

         13.3    Indemnification by Surviving Corporation and Parent. Subject
to the provisions of paragraph 13.4, Parent shall promptly indemnify, defend,
and hold Shareholders harmless against any and all losses, costs, and expenses
(including reasonable cost of investigation, court costs and legal fees) and
other damages resulting from (i) any breach by Parent or Surviving Corporation
of any of their covenants, obligations, representations or warranties or breach
or untruth of any representation or  warranty contained in this Agreement or
any certificate or document of Parent or Surviving Corporation delivered
pursuant to this Agreement, (ii) any claim which is brought or asserted by any
third party(s) against Shareholders for failure to pay or perform any of the

third party(s) against Shareholders arising out of the ownership, licensing,

employees, agents or independent contractors, relating to periods of time
subsequent to the Transaction Effective Date. Any indemnification payment
pursuant to the foregoing shall include interest at the Rate from the date that
the loss, cost, expense or damage was incurred until the date of payment.

         13.4    Rules Regarding Indemnification. The obligations and
liabilities of each party which may be subject to indemnification liability
hereunder (the "indemnifying party") to the other party (the "indemnified
party") shall be subject to the following terms and conditions:

                 (1)      Claims by Non-parties. The indemnified party shall
give written notice within a reasonably prompt period of time to the
indemnifying party of any written claim by a third party which is likely to
give rise to a claim by the indemnified party against the indemnifying party
based on the indemnity agreements contained in this Article, stating the nature
of said claim and the amount thereof, to the extent known. The indemnified
party shall give notice to the indemnifying party that pursuant to the
indemnity, the indemnified





                                      32
<PAGE>   38

party is asserting against the indemnifying party a claim with respect to a
potential loss from the third party claim, and such notice shall constitute the
assertion of a claim for indemnity by the indemnified party. If, within thirty
(30) days after receiving such notice, the indemnifying party advises the
indemnified party that it will provide indemnification and assume the defense
at its expense, then so long as such defense is being conducted, the
indemnified party shall not settle or admit liability with respect to the claim
and shall afford to the indemnifying party and defending counsel reasonable
assistance in defending against the claim. If the indemnifying party assumes
the defense, counsel shall be selected by such party and if the indemnified
party then retains its own counsel, it shall do so at its own expense. If the
indemnified party does not receive a written objection to the notice from the
indemnifying party within thirty (30) days after the indemnifying party's
receipt of such notice, the claim for indemnity shall be conclusively presumed
to have been assented to and approved, and in such case the indemnified party
may control the defense of the matter or case and, at its sole discretion,
settle or admit liability. If within the aforesaid thirty (30) day period the
indemnified party shall have received written objection to a claim (which
written objection shall briefly describe the basis of the objection to the
claim or the amount thereof, all in good faith), then for a period of ten (10)
days after receipt of such objection the parties shall attempt to settle the
dispute as between the indemnified and indemnifying parties. If they are unable
to settle the dispute, the unresolved issue or issues shall be settled by
arbitration in Los Angeles, California in accordance with the rules and
procedures of the American Arbitration Association.

                 (2)      Claims by a Party. The determination of a claim
asserted by a party hereunder (other than as set forth in subparagraph (1)
above) pursuant to this Article shall be made as follows: The indemnified party
shall give written notice within a reasonably prompt period of time to the
indemnifying party of any claim by the indemnified party which has not been
made pursuant to subparagraph (1) above, stating the nature and basis of such
claim and the amount thereof, to the extent known. The claim shall be deemed to
have resulted in a determination in favor of the indemnified party and to have
resulted in a liability of the indemnifying party in an amount equal to the
amount of such claim estimated pursuant to this paragraph if within forty-five
(45) days after the indemnifying party's receipt of the claim the indemnified
party shall not have received written objection to the claim. In such event,
the claim shall be conclusively presumed to have been assented to and approved.
If within the aforesaid forty-five (45) day period the indemnified party shall
have received written objection to a claim (which written objection shall
briefly describe the basis of the objection to the claim or the amount thereof,
all in good faith), then for a period of sixty (60) days after receipt of such
objection the parties shall attempt to settle the disputed claim as between the
indemnified and indemnifying parties. If they are unable to settle the disputed
claim, the unresolved issue or issues shall be settled by arbitration in Los
Angeles, California in accordance with the rules and procedures of the American
Arbitration Association.  Notwithstanding the provisions of this clause (2),
the enforcement provisions set forth in paragraph 14.2 will be available in the
event of a breach of paragraph 14.1.

                 (3)      Claims by a Straddle Patient. Any claim by a patient
relating to professional negligence or similar matters involving a patient
served both prior to the





                                      33
<PAGE>   39

Transaction Effective Date and subsequent to the Transaction Effective Date
will be the responsibility of either Parent or Shareholders in accordance with
the following guidelines: (i) if it is a claim in which the incident giving
rise to liability clearly arose prior to the Transaction Effective Date,
Shareholders shall respond to the loss and defense expenses; (ii) if it is a
claim in which the incident giving rise to liability clearly arose on or after
the Transaction Effective Date, Parent shall respond to the loss and defense
expenses; and (iii) in the event that the incident giving rise to liability as
to time is not clear, Shareholders and Parent will jointly defend the case and
each will fully cooperate with the other in such defense. Once the case is
closed, if Parent and Shareholders cannot agree to the allocation of both
indemnity and expenses, then the matter shall be submitted to binding
arbitration in Los Angeles California in accordance with the rules and
procedures of the American Arbitration Association. Notwithstanding anything
seemingly to the contrary contained herein, no indemnification shall be made
hereunder until agreed to by the parties hereto or settled in arbitration.

         13.5    Indemnity Period. The representations, warranties and
covenants, and the indemnity obligations related thereto, under this Agreement
shall expire 24 months from the Closing, except for claims under sections 4.13
and 4.28 hereof, which shall expire upon the expiration of the applicable
statute of limitations, and except for claims under sections 4.9 or 4.25
hereof, which shall expire on the earlier of the expiration of the applicable
statue of limitations or 48 months from Closing.  The indemnification
obligations under this Agreement shall not expire as provided herein for a
claim made, but not resolved, within the above periods.

         13.6    Limitation on Claims.  The limitations provided in this
Section 13.6 apply solely to the liability of the Shareholders.  The
obligations of an indemnifying party under this Agreement shall not begin until
the indemnified party incurs one or more liabilities which equal Two Hundred
Thousand and No/100 Dollars ($200,000.00) (the "Basket").  Once the Basket is
reached, the obligations of an indemnifying party under this Agreement shall
apply to all claims of the indemnified party, whether such claims are part of
the Basket or in excess thereof.  In no event shall the obligations of an
indemnifying party and its affiliates under this Agreement exceed Four Million
Dollars ($4,000,000.00) (the "Cap").  Notwithstanding the foregoing, the Basket
and the Cap shall not apply to any payroll or withholding issues related to
Shareholders.


                     ARTICLE XIV. PRESERVATION OF BUSINESS
                          AND NONCOMPETE RESTRICTIONS

         14.1    Covenant Not to Compete. Shareholders hereby jointly and
severally covenant and agree with Parent that, during the NON-COMPETE PERIOD
(as such term is defined herein) and within the NON-COMPETE AREA (as such term
is defined herein), neither of the Shareholders shall directly or indirectly,
(a) acquire, lease, manage, consult for, serve as agent or subcontractor for,
finance, invest in, own any part of or exercise management control over any
health care operation or business which provides any goods





                                      34
<PAGE>   40

or services competitive with the goods and services provided by the Business as
of the Closing, or (b) solicit for employment or employ any person who at
Closing or thereafter became an employee of Parent, Surviving Corporation or an
affiliate unless such person is not so employed for at least six (6) months, or
(c) with respect to any customer, patient, physician, physician group, or
healthcare provider with whom Parent, Surviving Corporation and/or an Affiliate
contracts with in connection with the Business, either solicit the same in a
manner which could adversely affect Parent, Surviving Corporation or an
Affiliate, or make statements to the same which disparage Parent, Surviving
Corporation, an Affiliate or their respective operations in any way. The
"Non-Compete Period" shall commence at the Closing and terminate on the third
anniversary thereof. The "Non-Compete Area" shall mean the area within a fifty
(50) mile radius of each location from which the Business or the Related
Business is operated or conducted as of the Closing. Ownership of less than
five percent (5%) of the stock of a publicly held company shall not be deemed a
breach of this covenant.

         14.2    Enforceability. In the event of a breach of paragraph 14.1,
Shareholders recognizes that monetary damages shall be inadequate to compensate
Parent and Surviving Corporation, and Parent and Surviving Corporation shall be
entitled, without the posting of a bond or similar security and notwithstanding
the arbitration provisions contained in Article XIII, to an injunction
restraining such breach, with the costs (including attorney's fees) of securing
such injunction to be borne by Shareholders. Nothing contained herein shall be
construed as prohibiting Parent or Surviving Corporation from pursuing any
other remedy available to either for such breach or threatened breach.  All
parties hereby acknowledge the necessity of protection against the competition
of Shareholders and that the nature and scope of such protection has been
carefully considered by the parties. The period provided and the area covered
are expressly represented and agreed to be fair, reasonable and necessary. The
consideration provided for herein is deemed to be sufficient and adequate to
compensate Shareholders for agreeing to the restrictions contained in paragraph
14.1. If, however, any court determines that the forgoing restrictions are not
reasonable, such restrictions shall be modified, rewritten or interpreted to
include as much of their nature and scope as will render them enforceable.


                           ARTICLE XV. MISCELLANEOUS

         15.1    Assignment. Following Closing, Parent and Surviving
Corporation may freely assign any or all of their respective rights or delegate
any or all of their respective obligations under this Agreement without the
express written consent of Shareholders; provided however, that Parent shall
remain primarily liable with regard to its obligations hereunder.  No
Shareholders may assign any rights or delegate any obligations under this
Agreement without the prior written consent of Parent, and any prohibited
assignment or delegation will be null and void.

         15.2    Other Expenses. Except as otherwise provided in this
Agreement, Shareholders shall pay all of their and Company's expenses in
connection with the





                                      35

negotiation, execution, and implementation of the transactions contemplated
under this Agreement and Parent shall pay all of its and Capstone Sub's
expenses in connection with the negotiation, execution, and implementation of
the transactions contemplated under this Agreement. All sales and use taxes,
recording fees and transfer taxes incurred in connection under the transactions

Effective Date between the Shareholders and Parent respectively, such that the
Shareholders pay all such taxes with respect to the Business up to the
Transaction Effective Date, and the Parent pays all such amounts thereafter.
Shareholders jointly and severally represent that, with respect to the laws of
the State of California, ad valorem or similar taxes are not applicable to the
transactions contemplated hereunder, and that Shareholders shall jointly and
severally indemnify Surviving Corporation and Parent for any costs incurred
from circumstances to the contrary.

         15.3    Notices. All notices, requests, demands, waivers and other
communications required or permitted to be given under this Agreement shall be
