     2.1 Collection of Receivables. After Closing, Company will proceed to
collect the Receivables. Shareholders shall provide such assistance in the

Article XIII; and (b) uncollected Receivables shall be assigned to Shareholders
provided that such Receivables relate to facilities that are not ongoing clients
of the Business or to private (non facility) payors. Company shall, and Buyer
shall cause Company to, diligently collect the Receivables with at least as much
effort and attention as Company has heretofore collected receivables. Company

Shareholders' Representative with a written monthly report scheduling in detail
progress on collection of the Receivables for such month. Responsible officers
of Company and Buyer shall, if requested, meet on at least a monthly basis with

Receivables. Any of the Receivables owed to the Company by Integrated Health
Services, Inc. shall be excluded from the Receivables Shortfall.

     3.1 Purchase Price. The purchase price payable by Buyer to Shareholders for
the Stock and in consideration for the agreements contained herein, including

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 not be merged into

warranties and covenants set forth in paragraphs 4.6 (as it relates to tax,
environmental or healthcare matters), 4.8, 4.9, 4.13, 4.25, 4.28 and 6.4 hereof
(collectively, the "Unrestricted Items"), each of which will survive the date of

     13.2 Indemnification by Shareholders. Subject to the provisions of
paragraph 13.4, Shareholders, including Optionees, shall jointly and severally
promptly indemnify, defend, and hold harmless Buyer, Parent, Company and the
directors, officers, stockholders, employees and 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 the covenants,
obligations, representations or warranties or breach or untruth of any
representation, warranty, fact or conclusion contained in this Agreement or any
certificate or document of Company and/or Shareholders delivered pursuant to
this Agreement, (ii) any liability of Company not expressly retained by Company
pursuant to Paragraph 1.4 hereof, and (iii) any claim (whether or not disclosed
herein) that is brought or asserted by any third party(s) against Buyer, Parent,
or Company arising out of the ownership, licensing, operation or conduct of the
Business or Assets or the conduct of any of


                                       31


<PAGE>   37

Company's employees, agents or independent contractors, relating to all periods
of time prior to Effective Date, subject to the limitations of Section 13.1
above.

     13.3 Indemnification by Company, Buyer, and Parent. Subject to the
provisions of paragraph 13.4, Company, Buyer, and Parent shall promptly jointly
and severally 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
Buyer or Parent of any of their covenants, obligations, representations or
warranties or breach or untruth of any representation, warranty, fact or
conclusion contained in this Agreement or any certificate or document of Buyer
or Parent 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 Continuing Liabilities, and (iii) subject to the other

party(s) against Shareholders arising out of the ownership, licensing, operation
or conduct of the Business or the conduct of any of Company's employees, agents
or independent contractors, relating to periods of time subsequent to Effective
Date.

     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 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. In no circumstances
shall an indemnifying party be liable for the fees and expenses of more than one
firm of lawyers, notwithstanding multiple indemnified parties and conflicts of
interest. 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


                                       32

<PAGE>   38

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.

          (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.

          (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 Effective Date and subsequent to the Effective Date will be the
responsibility of either Buyer 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 Effective Date, Shareholders shall jointly and
severally respond to the loss and defense expenses; (ii) subject to the other
provisions of this Agreement, if it is a claim in which the incident giving rise
to liability clearly arose on or after the Effective Date, Buyer 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 Buyer will
jointly defend the case and each will fully cooperate with the other in such
defense. Once the case is closed, Buyer and Shareholders shall agree to the
allocation of both indemnity and expenses.

          (4) Limitation on Claims. The obligations of each of the Shareholders
under this Agreement shall not exceed the amounts received by such Shareholder
as Purchase Price and, if applicable, as consideration for those certain
Non-Competition Agreements referenced in paragraph 8.5 and 9.7 hereof. As to a
claim by the Buyer or Company against Shareholders, all claims by the Buyer and
Company against Shareholders will be first satisfied by offsetting the principal
amount and any interest due thereunder of those of the Debentures which are held
by Shareholders, the signatures of the Shareholders on this Agreement serving as
evidence of the consent to such offsets,



                                       33



<PAGE>   39

provided however that the Shareholders shall in no event be liable for any loss,
cost or expense arising from the occurrence or allocable to a time period prior
to the Closing, which loss, cost or expense would be barred by an applicable
statute of limitations but for a waiver by the Company after the Closing of such
statute of limitations. The restrictions of this section shall not, however,
restrict or limit in any manner the claims the Company may have against a
Shareholder outside this agreement, including, but not limited to, claims for
payment for services and goods provided by the Company to the Shareholder or the
Shareholder's business.

          (5) Contribution among Shareholders. The several Shareholders,
including Optionees, agree to contribute or reimburse one another, as the case
may be, pro-rata according to their respective shareholdings (or in the case of
the Optionees their respective percentages of the gross proceeds paid by the
Buyer under Section 3.1 above) immediately prior to Closing, all amounts for
which any one or more of them may be liable hereunder in excess of his or their
pro-rata share, for any claim asserted hereunder by the Company, Buyer or,
directly or indirectly, any third party, against them or any one or more of
them, except for any such claim directly or entirely attributable to a
particular Shareholder arising out of an act or omission of such Shareholder
after Closing or arising out of the failure of a Shareholder or any business
enterprise controlled by the Shareholder to pay any receivable owing to the
Company. All disputes concerning the obligations of the several Shareholders to
contribute or reimburse hereunder shall be determined in arbitration in San
Francisco, California but as otherwise provided herein.


                      ARTICLE XIV. PRESERVATION OF BUSINESS
                           AND NONCOMPETE RESTRICTIONS

     14.1 Covenant Not to Compete. Shareholders hereby covenant and agree with
Buyer that, during the NON-COMPETE PERIOD (as such term is defined herein),
within the NON-COMPETE AREA (as such term is defined herein), and with respect
to the NON-COMPETE BUSINESS (as such term is defined herein), no 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 Non-Compete Business as of the Closing, or (b)
solicit for employment or employ any person who at Closing or thereafter became
an employee of Buyer, Company 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 Buyer,
Company and/or an Affiliate contracts with in connection with the Non-Compete
Business, either solicit the same in a manner which could adversely affect
Buyer, Company or an Affiliate, or make statements to the same which disparage
Buyer, Company, an Affiliate or their respective operations in any way. The
"Non-Compete Period" shall commence at the Closing and terminate on the second
anniversary thereof. The "Non-Compete Area" shall mean the counties of Northern
California in which, for the one calendar year period prior to Closing, Company
has had repeat Non-Compete Business. The term "Non-Compete


                                       34

<PAGE>   40

Business" shall mean institutional sales of pharmaceutical products by the
Company. 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. Notwithstanding the provisions herein for the
determination of disputes in arbitration, in the event of a breach of paragraph
14.1, Shareholders recognize that monetary damages shall be inadequate to
compensate Buyer and Company, and Buyer and Company 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 the breaching Shareholder(s). Nothing contained herein shall be
construed as prohibiting Buyer or Company 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. In addition,
Shareholders receiving less than $50,000 for selling their shares to the Company
cshall not be barred by provisions of this Article XIV from working for a
competing business in a non-managerial position.


                             ARTICLE XV. ARBITRATION

     15.1 Arbitration. Any and all disputes hereunder or concerning the judicial
interpretation hereof or with respect to the transactions contemplated herein,
shall be finally determined in binding Arbitration before a single arbitrator
under the then rules of the American Arbitration Association and any award in
such arbitration may be entered in and enforced by any court having
jurisdiction. It is the intention of the parties to arbitrate and the Federal
Arbitration Act shall pre-empt any local law with respect to the obligation to
arbitrate.

     15.2 Third Party Claims. Notwithstanding the terms of the foregoing
paragraph 15.1, where any disputed matter concerns the liability of a party
hereto to indemnify or to be indemnified on account of a claim initiated by a
third party not a party to this Agreement and pending in any court, then such
matter shall be determined judicially.

     15.3 Venue. Any Arbitration hereunder shall be conducted in San Francisco,
California, if initiated by Company or Buyer against the Shareholders or any of
them; and, in Dallas, Texas, if initiated by the Shareholders or any of them
against Company or Buyer.


                                       35


<PAGE>   41

     15.4 Power of Arbitrator. The Arbitrator shall have no power or authority
to award consequential, statutory or punitive damages, or to assess interest on
any award.

     15.5 Costs and Expenses. In the event any party hereto incurs reasonable
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.


                           ARTICLE XVI. MISCELLANEOUS

     16.1 Assignment. Following Closing, Buyer and Company may freely assign any
or all of their respective rights or delegate any or all of their respective

Business up to the Effective Date, and the Buyer pays all such amounts
thereafter. Shareholders 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 indemnify
Company and Buyer for any costs incurred from circumstances to the contrary.

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

     16.9 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.

     16.10 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.

     16.11 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 best knowledge of Company or Shareholders" or the like is used,
Company and Shareholders shall each be deemed to have the knowledge of Company's
officers, directors, Shareholders and employees, and of its Affiliates; and
Company and Shareholders shall each be under a duty of due inquiry.

     16.12 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 Buyer, Company and Shareholders.

     16.13 Further Assurance of Shareholders After Closing. Subsequent to the
Closing, Shareholders shall from time to time, at Buyer's request, execute and
deliver such other instruments of conveyance and transfer, and take such other
action as Buyer may request, in order to more effectively sell, transfer, assign
and deliver and vest in Buyer and Company, as the case may be, the benefits of,
title to and possession of the Stock and Assets.

     16.14 NON-APPLICABILITY OF ARTICLE XIV. NOTWITHSTANDING ANYTHING TO THE
CONTRARY IN THIS AGREEMENT, STEVE STANGE ("STANGE") SHALL NOT BE SUBJECT TO ANY
OF THE RESTRICTIONS OF ARTICLE XIV (PRESERVATION OF BUSINESS AND NONCOMPETE
RESTRICTIONS) OF THIS AGREEMENT OR ANY OTHER RESTRICTION OR LIMITATION OF ANY
KIND WITH RESPECT TO COMPETITION WITH, OR SOLICITATION OF THE CUSTOMERS OF, THE
COMPANY, BUYER OR CAPSTONE, OR THE PRESERVATION OF CONFIDENTIAL OR PROPRIETARY
INFORMATION.
