(terms defined in the singular to have the same meanings when used in the plural
and vice versa):

            (a) "Accounts Receivable" shall mean all accounts and notes
receivable, claims, debtor obligations and other rights to receive payments from
third parties of each Seller relating 
<PAGE>

to its Business, existing on the Closing Date.

            (b) "Accountants" shall have the meaning set forth in Section
3.3(a).

            (c) "Affiliates" shall mean any individual, corporation,
partnership, joint venture, association, trust or unincorporated organization

whether through ownership of securities or partnership or other ownership
interests, by contract or otherwise, provided, however, that in the case of any
Seller, the term "Affiliates" shall also include each other Seller, and each
Shareholder of such Seller.

            (d) "Agreement" shall mean this Asset Purchase Agreement, as it may
be amended, modified or supplemented from time to time in accordance with its

Sellers, the Year 3 Earn-Out in cash by wire transfer of immediately available
funds, and the Escrow Agent shall transfer the Escrow Funds to AHG, on behalf of
the Sellers.

            (d) Distributions of Interest or Earnings on the Escrow Funds.
Interest or other earnings on the Escrow Deposit and additional amounts paid by
the Buyer to the Escrow Agent pursuant to this Section 3.4 shall be disbursed

instructions to disburse to AHG, on behalf of the Sellers, an amount from the
Escrow Funds necessary for the Sellers to pay their federal income tax liability
on said interest and earnings, assuming for purposes hereof an effective tax
rate of 31%. The amount of any previous distributions for taxes made to AHG, on
behalf of the Sellers, shall be taken into account in the event that
disbursements from the Escrow Funds are later made to the Buyer and appropriate
adjustments will be made in accordance with joint instructions from the Buyer
and AHG to the Escrow Agent.

            (e) Limitations on Purchase Price Adjustments/ EarnOuts.

            (f) Adjustments in Excess of Escrow Funds. In the event that the
Adjustment for any Earn-Out Period should exceed the amount of the remaining
Escrow Funds, the amount of such excess shall be applied as a credit in favor of
the Buyer and shall be deducted from the amount otherwise payable by the Buyer
as the Year 2 Earn-Out and Year 3 Earn-Out, as applicable.

relation to such person's employment or engagement with any of the Sellers or

or similar transaction involving any Seller or any of the Businesses or any
other transaction inconsistent with the transactions contemplated hereby. The
Sellers and the Executive Shareholders shall promptly communicate to the Buyer

receive or of which they may become aware prior to the termination of this
Agreement.

written consent of the Buyer, they shall not, jointly or severally, provide or
have any interest in any Person that provides or is engaged in, whether as an
owner, employee, officer, director, shareholder, partner, contractor,
consultant, agent, joint venturer, or advisor, (i) subspecialty capitated or
discounted fee for service networks, or related administrative or management
services, to any Person providing, directly or indirectly, health care services
or (ii) the business presently engaged in, or engaged in at such time by any

pursuant to this Agreement and the substantial relationships (as reflected, in
part, in the Contracts)

            with payors and other medical providers and patients that are being
transferred to the Buyer as contemplated by this Agreement.
<PAGE>

            (c) The Sellers and the Executive Shareholders agree that a monetary
remedy for a breach of the agreement set forth in Section 7.9(a) hereof will be
inadequate and impracticable and further agree that such a breach would cause
the Buyer irreparable harm, and that the Buyer shall be entitled to temporary
and permanent injunctive relief without the necessity of proving actual damages.
In the event of such a breach, the Sellers and the Executive Shareholders agree
that, in addition to all other remedies available at law or in equity, the Buyer
shall be entitled to such injunctive relief, including temporary restraining
orders, preliminary injunctions and permanent injunctions as a court of

the minimum extent required for its validity under applicable laws and shall be
binding and enforceable with respect to each Seller and each Shareholder as so
curtailed.

            (e) The foregoing five-year period shall be tolled for any period(s)
of violation or period(s) of time required for litigation to enforce the
covenants herein.

            Section 7.10 Non-Solicitation of Employees. The Sellers and the
Executive Shareholders agree for themselves and their respective Affiliates, for
a period commencing on the Closing Date hereof and ending on the fifth

contractor of Buyer or an Affiliate of Buyer, without the written consent of the
Buyer.

            Section 7.11 Assignment of Contracts and Warranties. Each Seller
assigns to the Buyer effective from and after the Closing all right, title and
interest of each Seller and its Affiliates in, to and under the Contracts.
Notwithstanding the foregoing, no Contract shall be assigned contrary to law or
the terms of such Contract and, with respect to Contracts that cannot be
assigned to the Buyer, the performance obligations of the applicable Seller
thereunder shall, unless not permitted by such Contract, be deemed to be
subleased or subcontracted to the Buyer until such Contract has been assigned.
The Buyer shall reasonably assist each Seller in obtaining any necessary
approvals to such subleases and subcontracts. The Buyer shall take all necessary
actions to perform and complete all Contracts in accordance with their terms if
neither assignment, subleasing nor subcontracting is permitted by the other
party, and each Seller shall pay over to the Buyer any amounts received by such
Seller after the Closing Date as a result of performance by the Buyer of such
Contracts; provided; however, to the extent any such Contract is a Key Contract,
nothing set forth herein shall require the Buyer to assume any obligation of any
of the Sellers under such Key Contract until the consent to assignment with
respect thereto has been obtained unless the Buyer shall have waived the
requirement that such consent be obtained as a condition to Closing as
contemplated in Section 8.7 hereof.

without regard to whether the indemnifying Seller or Executive Shareholder made
such representation or breached such warranty (including, without limitation,
(i) any misrepresentation in, or omission from, any statement, certificate,

part of any Seller or any Executive Shareholder to be performed or observed;

            (c) any claim or cause of action by any party against any Buyer

proviso, the Sellers and the Executive Shareholders shall have no obligation to
make any payment under Section 11.1(a) with respect to any representation or
warranty made in good faith without actual knowledge or notice of falsity unless
the aggregate amount to which all Buyer Indemnitees are entitled by reason of
all such claims exceeds $100,000, it being understood that once such amount is

any amount in excess thereof) shall be payable jointly and severally by the
Sellers and the Executive Shareholders to the Buyer. In addition, the Sellers
and the Executive Shareholders shall have no obligation to make any payment

Sellers' Event of Breach occurs or is alleged and a Buyer Indemnitee asserts
that the Sellers or any of the Executive Shareholders has become obligated to
such Buyer Indemnitee pursuant to Section 11.1, or if any suit, action,
investigation, mediation, claim or proceeding is begun, made or instituted as
<PAGE>

obligated to a Buyer Indemnitee hereunder, such Buyer Indemnitee shall give
written notice to the Sellers and the Executive Shareholders. The Sellers and
the Executive Shareholders agree to jointly and severally defend, contest or
otherwise protect the Buyer Indemnitee against any such suit, action,
investigation, claim or proceeding at their sole cost and expense. The Buyer
Indemnitee shall have the right, but not the obligation, to participate at its
own expense in the defense thereof by counsel of the Buyer Indemnitee's choice
and shall in any event cooperate with and assist the Sellers and the Executive
Shareholders to the extent reasonably possible. If the Sellers and the Executive
Shareholders fail to timely defend, contest or otherwise protect against such
suit, action, investigation, claim or proceeding, the Buyer Indemnitee shall
have the right to do so, including the right to make any compromise or
settlement thereof, and the Buyer Indemnitee shall be entitled to recover the
entire cost thereof jointly and severally from the Sellers or the Executive
Shareholders, including reasonable attorneys' fees, disbursements and amounts
paid as the result of such suit, action, investigation, mediation, claim or
proceeding.

has a claim against any of Sellers or Executive Shareholders for indemnification
pursuant to this Section 11 or as a result of the failure by the Sellers or the

Section 3, the Buyer may set-off the amount of such Losses against any amounts
payable directly or indirectly by or on behalf of the Buyer to the Sellers from
time to time pursuant to this Agreement or the agreements and documents
referenced herein, including without limitation any amounts payable by the Buyer
to the Escrow Agent pursuant to Section 3.

            Section 11.4 Indemnification by the Buyer and Parent.

regardless of any investigation at any time made by or on behalf of the Sellers
or the Executive Shareholders or of any knowledge or information that the
Sellers or the Executive Shareholders may have, the Buyer and Parent shall
jointly and severally indemnify and agree to fully defend, save and hold each of
the Sellers, and its directors, officers and employees, and each Executive
Shareholder (collectively, the "Seller Indemnitees"), harmless if any Seller
Indemnitee shall at any time or from time to time suffer any Losses arising out
of or resulting from, or shall pay or become obligated to pay any sum on account
of, any Buyer's Event of Breach. As used herein, "Buyer's Event of Breach" shall
be and mean any one or more of the following:

            (i) any untruth or inaccuracy in any representation of the Buyer or
Parent or the breach of any warranty of the Buyer or Parent contained in this
Agreement;

            (ii) any failure of the Buyer or Parent duly to perform or observe
any term, provision, covenant, agreement or condition contained in this
Agreement on the part of the Buyer or Parent to be performed or observed; and

            (iii) any claim or cause of action by any party against any Seller
Indemnitees with respect to Assumed Liabilities;

provided, however, that neither the Buyer nor Parent shall have any obligation
to make any
<PAGE>

payment under Section 11.4(a) with respect to any representation or warranty
made in good faith without actual knowledge or notice of falsity unless the
aggregate amount to which all Seller Indemnitees are entitled by reason of all
such claims exceeds $100,000, it being understood that once such amount is
exceeded, the aggregate of all such claims (including such $100,000 amount and
any amount in excess thereof) shall be payable by the Buyer and Parent on demand

            Section 11.5 Procedures for Indemnification by the Buyer and Parent.
If a Buyer's Event of Breach occurs or is alleged and a Seller Indemnitee
asserts that the Buyer or Parent has become obligated to it pursuant to Section
11.4, or if any suit, action, investigation, claim or proceeding is begun, made
or instituted as a result of which the Buyer or Parent may become obligated to a
Seller Indemnitee hereunder, such Seller Indemnitee shall give written notice to
the Buyer and Parent. The Buyer and Parent agree to defend, contest or otherwise
protect such Seller Indemnitee against any such suit, action, investigation,
claim or proceeding at its sole cost and expense. Such Seller Indemnitee shall
have the right, but not the obligation, to participate at its own expense in the
defense thereof by counsel of its choice and shall in any event cooperate with
and assist the Buyer or Parent to the extent reasonably possible. If the Buyer
or Parent fails timely to defend, contest or otherwise protect against such
suit, action, investigation, claim or proceeding, such Seller Indemnitee shall
have the right to do so, including the right to make any compromise or
settlement thereof, and such Seller Indemnitee shall be entitled to recover the
entire cost thereof from the Buyer or Parent including reasonable attorneys'
fees, disbursements and amounts paid as the result of such suit, action,
investigation, claim or proceeding.

Section 11.6 The Sellers' and Executive Shareholders' Right of Set-Off. In the
event the Sellers or Executive Shareholders have a claim against the Buyer or
Parent for indemnification pursuant to this Section 11 or as a result of the
failure by the Buyer or Parent to pay the Sellers any amounts owed to them
pursuant to Section 3, the Sellers and Executive Shareholders may set-off the
amount of such Losses against any amounts payable directly or indirectly by or
on behalf of the Sellers or Executive Shareholders to the Buyer or Parent from
time to time pursuant to this Agreement or the agreements and documents
referenced herein, including without limitation any amounts payable by the
Sellers or Executive Shareholders pursuant to Section 3.

            Section 11.7 Purchase Price Adjustment. The Buyer and each of the
Sellers agree to treat any payments under this Section 11 as an adjustment to
the Purchase Price for all federal, state and local Tax purposes.

intended to confer any rights or remedies under or by reason of this Agreement
on any persons other than the Sellers, and the Buyer and their respective

            Section 12.11 Scheduled Disclosures. Disclosure of any matter, fact
or circumstance in a Schedule to this Agreement shall not be deemed to be
disclosure thereof for purposes of any other Schedule hereto.

            Section 12.12 Section and Paragraph Headings. The section and
paragraph headings in this Agreement are for reference purposes only and shall
not affect the meaning or interpretation of this Agreement.

            Section 12.13 Counterparts. This Agreement may be executed in

            Section 12.14 Post-Closing Survival. All covenants and agreements

involved.

which may be available to it, the Buyer will have the right to obtain injunctive
relief to restrain a breach or threatened breach of, or otherwise obtain
specific performance of, the Sellers'
<PAGE>

and the Executive Shareholders' covenants and other agreements contained in this
