this Section 9.2 and Article 11.

                                   ARTICLE 10

                      INDEMNIFICATION AND RELATED MATTERS.

     Section 10.1  INDEMNIFICATION BY THE COMPANY.  Subject to the limitations
set forth in this Article 10 and elsewhere in this Agreement, the Company shall
indemnify the Purchaser against any Damages that the Purchaser actually incurs
during the one-year period commencing on the Closing Date which arise from,
occur as a result of or in connection with (a) any breach by the Company of any
representation, warranty or covenant of the Company set forth in this Agreement
or any of the Acquisition Documents or (b) any liability that arises from or
relates to (i) the Excluded Assets or (ii) the Excluded Liabilities.

     Section 10.2  INDEMNIFICATION BY THE PURCHASER.  Subject to the limitations
set forth in this Article 10 and elsewhere in this Agreement, the Purchaser
shall indemnify the Company and the Owners against any Damages that the Company
actually incurs during the one-year period commencing on the Closing Date which
arise from, occur as a result of or in connection with (a) any breach by the
Purchaser of any representation, warranty or covenant of the Purchaser set forth
in this Agreement or any of the Acquisition Documents, or (b) any liability that
arises from or relates to (i) the operation of the  Purchased Assets after the
Closing, and (ii) the Assumed Liabilities.

     SECTION 10.3  EXPIRATION OF REPRESENTATIONS, WARRANTIES AND COVENANTS.
Except for the covenants set forth in Section 6.2(b) (sales taxes), the
covenants set forth in Article 6 shall terminate and expire, and shall cease to
be of any force or effect, on the Closing Date, and all liability of the parties
hereto with respect to such covenants shall thereupon be extinguished.  Except
as set forth in the immediately preceding sentence, all of the representations,
warranties, covenants and obligations of the Company and the Purchaser set forth
in this Agreement and any of the Acquisition Documents shall terminate and
expire, and shall cease to be of any force or effect, at 2:00 p.m. (California
time) on the first anniversary of the Closing Date, and all liability of the
Company or the Purchaser with respect thereto (including their respective
obligations under Section 10.1 or Section 10.2, as the case may be) shall
thereupon be extinguished; provided, that if, prior to such first anniversary,
either party shall have duly delivered a Claim Notice in conformity with all of
the applicable procedures set forth in Section 10.8, then the specific
indemnification claim set forth in such Claim Notice shall survive such first
anniversary (and shall not be extinguished thereby).

     Section 10.4  DEDUCTIBLE AMOUNT.  Without limiting the effect of any of the
other limitations set forth herein, neither the Purchaser nor the Company shall
be required to make any indemnification payment hereunder with respect to any
breach of any of their respective representations, warranties, covenants and


                                      16.

 
obligations, except to the extent that the cumulative amount of the Damages
actually incurred by the party to be indemnified as a result of all such
breaches of such representations, warranties, covenants and obligations actually
exceeds the Deductible Amount; and each party hereto shall only be required to
pay, and shall only be liable for, the amount by which the cumulative amount of
the Damages actually incurred by the party to be indemnified as a result of all
such breaches of such representations, warranties, covenants and obligations
actually exceeds the Deductible Amount. The "Deductible Amount" shall be an
amount equal to one-half percent (0.5%) of the Purchase Price. Notwithstanding
the foregoing, claims for indemnification relating to (i) the Excluded
Liabilities (including, without limitation, taxes of the Company described in
such definition and Overpayments) and (ii) (a) the Assumed Liabilities and (b)
the operation of the Purchased Assets after the Closing, shall not be subject to
the Deductible Amount.

     Section 10.5  MAXIMUM LIABILITY.  The total amount of the payments that
either the Company or the Purchaser, as the case may be, shall be required to
make under or in connection with this Agreement or any of the Acquisition
Documents pursuant to such party's indemnification obligations shall be limited
in the aggregate to a maximum of ten percent (10%) of the Purchase Price, and
neither party's respective cumulative liability shall exceed such amount.

     Section 10.6  KNOWLEDGE OF BREACH.  For purposes of this Article 10,
neither party hereto shall be deemed to have breached any representation or
warranty if the other party had, on or prior to the Closing Date, Knowledge of
the breach of, or of any facts or circumstances constituting or resulting in a
breach of, such representation or warranty.

     Section 10.7  NO IMPLIED REPRESENTATIONS.  The Purchaser and the Company
acknowledge that, except as expressly provided in Articles 4 and 5, neither
party hereto, and none of the Associates of either party hereto, has made or is
making any representations or warranties whatsoever, implied or otherwise.

     Section 10.8  INDEMNIFICATION CLAIMS.  If either party hereto (the
"Claimant") wishes to assert an indemnification claim against the other party
hereto, the Claimant shall deliver to the other party a written notice (a "Claim
Notice") setting forth:

          (a)  the specific representation, warranty or covenant alleged to have
been breached by such other party, or the specific liability to have been
incurred;

          (b)  a detailed description of the facts and circumstances giving rise
to the alleged breach of such representation, warranty or covenant, or
incurrence of such liability; and

          (c)  a detailed description of, and a reasonable estimate of the total
amount of, the Damages actually incurred or expected to be incurred by the
Claimant as a direct result of such alleged breach.

Notwithstanding anything to the contrary contained in this Agreement, Claimant
shall not be permitted to deliver any Claim Notice to the other party (and shall
not be entitled to assert any indemnification claim set forth in any Claim
Notice) unless:

                  (i) the indemnification claim set forth in such Claim Notice
shall have arisen from a bona fide lawsuit or other bona fide legal proceeding
that was instituted by a third party against Claimant or the Company prior to
the delivery of such Claim Notice to the other party; or

                  (ii) Claimant shall have provided evidence in reasonable
detail demonstrating to the other party, before the delivery of such Claim
Notice, that Claimant has therefore actually incurred, or is reasonably likely
to incur, Damages as a result of the alleged breach described in such Claim
Notice.


                                      17.

 
Any Claim Notice that is delivered to the Purchaser or the Company in
contravention of the prohibition set forth in the preceding sentence shall be
deemed not to have been "duly delivered" for purposes of Section 10.3 and shall
be of no force or effect.

     Section 10.9  DEFENSE OF THIRD PARTY ACTIONS.  If either party hereto (the
"Indemnitee") receives notice or otherwise obtains knowledge of any Matter or
any threatened Matter that may give rise to an indemnification claim against the
other party hereto (the "Indemnifying Party"), then the Indemnitee shall
promptly deliver to the Indemnifying Party a written notice describing such
Matter in reasonable detail; provided, that for the sole purpose of determining
whether a Matter or threatened Matter may give rise to an indemnification claim
against the Indemnifying Party within the meaning of this sentence, the
limitation set forth in Section 10.4 shall not be taken into account.  The
timely delivery of such written notice by the Indemnitee to the Indemnifying
Party shall be a condition precedent to any liability on the part of the
Indemnifying Party under this Section 10 with respect to such Matter.  The
Indemnifying Party shall have the right, at its option, to assume the defense of
any such Matter with its own counsel reasonably satisfactory to the Indemnitee.
If the Indemnifying Party elects to assume the defense of any such Matter, then:

          (a)  notwithstanding anything to the contrary contained in this
Agreement, the Indemnifying Party shall not be required to pay or otherwise
indemnify the Indemnitee against any attorneys' fees or other expenses incurred
on behalf of the Indemnitee in connection with such Matter following the
Indemnifying Party's election to assume the defense of such Matter;

          (b)  the Indemnitee shall make available to the Indemnifying Party all
books, records and other documents and materials that are under the direct or
indirect control of the Indemnitee and that the Indemnifying Party considers
necessary or desirable for the defense of such Matter;

          (c)  the Indemnitee shall fully cooperate as reasonably requested by
the Indemnifying Party in the defense of such Matter and execute such documents
and take such other actions as the Indemnifying Party may reasonably request for
the purpose of facilitating the defense of, or any settlement, compromise or
adjustment relating to, such Matter;

          (d)  the Indemnitee shall not admit any liability with respect to
such Matter; and

          (e)  the Indemnifying Party shall not settle, adjust or compromise
such Matter without the prior written consent or approval of the Indemnitee.

If the Indemnifying Party elects not to assume the defense of such Matter, then
the Indemnitee shall proceed diligently to defend such Matter with the
assistance of counsel satisfactory to the Indemnifying Party; provided, that the
Indemnitee shall not settle, adjust or compromise such Matter, or admit any
liability with respect to such Matter, without the prior written consent of the
Indemnifying Party.

     Section 10.10  SUBROGATION.  To the extent that either party hereto (the
"Indemnitor") makes or is required to make any indemnification payment to the
other party hereto (the "Indemnified Party"), the Indemnitor shall be entitled
to exercise, and shall be subrogated to, any rights and remedies (including
rights of indemnity, rights of contribution and other rights of recovery) that
the Indemnified Party or any of the Indemnified Party's Associates may have
against any other Person with respect to any Damages, circumstances or Matter to
which such indemnification payment is directly or indirectly related.  The
Indemnified Party shall permit the Indemnitor to use the name of the Indemnified
Party and the names of 

                                      18.

 
the Indemnified Party's Associates in any transaction or in any proceeding or
other Matter involving any of such rights or remedies; and the Indemnified Party
shall take such actions as the Indemnitor may reasonably request for the purpose
of enabling the Indemnitor to perfect or exercise the Indemnitor's right of
subrogation hereunder.

     Section 10.11  EXCLUSIVITY.  The right of each party hereto to assert
indemnification claims and receive indemnification payments pursuant to this
Article 10 shall be the sole and exclusive right and remedy exercisable by such
party with respect to any breach by the other party hereto of any
representation, warranty, covenant or obligation.  Without limiting the
generality of the foregoing, no Indemnitee shall have the right to withhold and
deduct any sum that may be owed to such Indemnitee from any amount otherwise
payable by such Indemnitee to the Indemnifying Party.

     SECTION 10.12  ACCOUNTS RECEIVABLE.  In the event the Company receives any
payment that relates to accounts receivable generated from services rendered by
the Business after the Closing Date, the Company shall promptly transmit these
funds to the Purchaser.  In the event the Purchaser receives any payment that
related to accounts receivable generated from services rendered by the Business
on or before the Closing Date, the Purchaser shall promptly transmit these funds
to the Company.

     SECTION 10.13  TAX MATTERS.  Each party will provide the other such
assistance as may reasonably be requested in connection with the preparation of
any reimbursement-related audit, any tax return, any audit or other examination
by any taxing authority, or any judicial or administrative proceedings relating
to liability for taxes, and each will retain and provide the other with any
records or information which may be relevant to such return, audit or
examination, proceedings or determination.  The party requesting assistance
hereunder shall reimburse the other party for reasonable expenses incurred in
providing such assistance.  Any information obtained pursuant to this Section or
pursuant to any other Section hereof providing for the sharing of information or
the review of any tax return or other schedule relating to taxes shall be kept
confidential by the Parties and not disclosed to any Person.

     SECTION 10.14  TAIL INSURANCE.  The Company shall use commercially
reasonable efforts to maintain in force and effect for five years from the
Closing Date the Tail Insurance Coverage relating back five years from the
Closing Date.  The "Tail Insurance Coverage" shall be health care services
professional liability coverage with The Doctors Company or such other
financially sound and reputable insurance company or association selected by the
Company with limits of liability of $1,000,000 per loss.

Agreement.

ensuring that the transactions contemplated by this Agreement are carried out in
full compliance with the provisions of all applicable laws and regulations.

     Section 11.3  PUBLICITY.  No press release, notice to any third party or
other publicity concerning the transactions contemplated by this Agreement or
any of the Acquisition Documents shall be issued, given or otherwise
disseminated without the prior written consent of the Agent and the Purchaser,
which will not be unreasonably withheld or delayed; provided, that (a) without
the approval of the Purchaser, the Agent 


                                      19.

 
shall be entitled to make disclosures regarding the transactions contemplated
hereby (i) to the Office of the California Attorney General and (ii) as may be

may make such disclosures as may be contemplated herein or as may be and to the
extent required by applicable law.

     Section 11.4  ACCESS OF THE COMPANY TO BOOKS AND RECORDS.  At all times
after the Closing Date, the Purchaser shall give the Company and the Company's
Associates reasonable access to the books and records of the Company to inspect

accordance with, and governed in all respects by, the laws of the State of
California (without giving effect to principles of conflicts of law).

     Section 11.6  VENUE AND JURISDICTION.  If any legal proceeding or other
legal action relating to this Agreement is brought or otherwise initiated, the
venue therefor shall be in San Francisco, California, which shall be deemed to
be a convenient forum.  The Purchaser and the Company hereby expressly and
