                                   AGREEMENT

         THIS AGREEMENT (the "Agreement"), made this 22nd day of November, 1996
by and among MHM Services, Inc., a corporation organized and existing under the
laws of the State of Delaware (hereafter referred to as "Buyer Parent") and its
wholly owned subsidiary MHM Extended Care Services, Inc., a corporation
organized and existing under the laws of the State of Delaware (hereinafter
referred to as "Buyer") and Liberty Management Group, Inc., a corporation
organized and existing under the laws of the Commonwealth of Massachusetts
(hereinafter referred to as "Seller Parent"), and its wholly owned subsidiary
Liberty Bay Colony Health Services, Inc., a corporation organized and existing
under the laws of the Commonwealth of Massachusetts (hereinafter referred to as
"Seller Sub" and, collectively with Seller Parent, as "Sellers").  The term
"Sellers" as used herein shall mean the Sellers or each or either of them, as
the context requires.

                             W I T N E S S E T H :

         WHEREAS, the business of Seller Sub consists of managing the provision
of mobile professional geripsych services for skilled nursing facilities, adult
day care centers, and assisted living facilities in Massachusetts (currently
numbering approximately sixty facilities), and providing such services to
residents of such facilities as well as counseling services to such residents'
families in such facilities (which counseling services are currently billed
under Medicare Procedure Codes 90846 and 90847)
<PAGE>   6
(hereinafter referred to as the "Business").

         WHEREAS, Buyer wishes to purchase from Sellers certain of the assets
and contractual rights of the Business owned by Sellers; and

         WHEREAS, Sellers wish to sell the said assets and contractual rights
to Buyer upon, under and subject to certain terms and conditions agreed upon by
and among the parties as hereinafter set forth; and

         NOW THEREFORE, intending to be legally bound hereby, and in
consideration of the mutual covenants herein contained and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto agree as follows:

         1.      PURCHASE AND SALE OF ASSETS

                 (a)      Buyer hereby agrees to purchase from Sellers and
Sellers agree to sell to Buyer the following assets and contractual rights
related to the Business (collectively, the "Assets"), owned by Sellers, for the
purchase price set forth in paragraph 2 hereinafter:

                                  (i)  All of Sellers' rights under or in
connection with certain agreements related to the Business in force on the
Closing Date (as hereinafter defined), as follows:  agreements relating to
managing the provision of mobile professional geripsych services for skilled
nursing facilities, adult day care centers and assisted living facilities and
providing such services to residents of such facilities as well as counseling
services to families of such residents in such facilities (which services are
currently billed under Medicare Procedure Codes 90846





                                       2
<PAGE>   7
and 90847), including, without limitation, the Sun Contract, as hereinafter
defined (each, a "Facility Contract" and collectively, "Facility Contracts") (a
list of those Facility Contracts in force on the date of this Agreement is
attached as EXHIBIT 1(a)(i) hereto).  Buyer and Sellers agree that all of
Sellers' rights under, or in connection with, agreements to be transferred to
Buyer pursuant to this subparagraph 1(a)(i) at the Closing (as hereinafter
defined) shall be as set forth above and in EXHIBIT 1(a)(i), with such
additions and deletions between the time of the execution of this Agreement and
the Closing that are entered into in the ordinary course of business;

                                  (ii)     All customer lists, records and
files, plans, systems, methods, designs, protocols, policies and procedures,
and books and records relating to the operations, personnel, vendors, suppliers
and customers of the Business; and

                                  (iii)    All personnel and payroll records of
employees of Sellers who become employees of Buyer after the Closing.

                 (b)      The Assets shall be transferred by Sellers to Buyer
free of all security interests, liens, encumbrances, and indebtedness of any
kind, provided, however, that all contracts are subject to the rights of the
other parties to such contracts.

                 (c)      Buyer shall not assume, nor be obligated to perform,
fulfill or pay, any obligations or indebtedness of Sellers or the Business
whatsoever, except that Buyer shall assume all obligations and indebtedness
related to the Business with respect to acts,





                                       3
<PAGE>   8
occurrences and obligations occurring or accruing on and after the Closing Date
under or in connection with the Assets.

                 (d)      The Assets to be transferred to Buyer hereunder shall
not include, and Sellers shall retain for their own account, any other assets
of the Business, including, without limitation, any and all licenses, leases,
computers, and furniture; any part of the trade name (except as expressly set
forth in paragraph 31 hereof); accounts receivable and related contract rights
and claims for the period prior to the Closing Date and records relating
thereto to the extent such records do not also relate to services to be
provided on or after the Closing Date; and similar related items.

                 (e)      Under the letter of intent dated September 17, 1996
between Sellers and Buyer, it was contemplated that Sellers would sell to Buyer
not only the Business but also a similar business in Connecticut operated by a
subsidiary of Seller Sub (the "Sellers' Connecticut Business").  After
consideration, Buyer has decided that it wants to purchase only the Business,
even though the Business and Sellers' Connecticut Business service some of the
same customers or affiliates thereof (collectively, the "Dual State
Customers").  Sellers have concluded that Buyer's purchase of the Business
makes the continuation of Sellers' Connecticut Business uneconomical and,
therefore, Sellers plan to close down or otherwise terminate Sellers'
Connecticut Business.  Notwithstanding anything contained to the contrary in
this Agreement, Sellers shall not have any liability under this Agreement
whatsoever (except for





                                       4
<PAGE>   9
any potential liability pursuant to the first sentence of Section 3(e)) if the
closure, termination or wind down of the Sellers' Connecticut Business results
in or contributes to the termination of any of the Facility Contracts by any
Dual State Customers.

         2.      PURCHASE PRICE

                 (a)      As consideration for the purchase of the Assets and
the restrictive covenants of Sellers, Buyer shall deliver to Sellers as the
Purchase Price hereunder:

                                  (i)  One Hundred and Fifty Thousand Dollars
($150,000.00) payable to Sellers jointly at the Document Closing (as
hereinafter defined), by wire transfer of immediately available funds;

                                  (ii) One Hundred and Fifty Thousand Dollars
($150,000.00) payable to Sellers jointly at the Document Closing by delivery of
an absolute, unconditional and fully negotiable promissory note dated as of the
Closing Date payable to the order of Sellers jointly, without offset or defense
of any kind or nature except for an offset of Seventy Five Thousand Dollars
($75,000.00) if the Sun Contract (as hereinafter defined) was invalid in its
entirety due to an act or omission of Sellers prior to the Closing (other than
the entry into of this Agreement or consummation of the transactions
contemplated hereby), guaranteed by Buyer Parent, which note shall provide for
quarterly payments of interest at the annual rate of nine percent (9%) and a
balloon payment of the principal amount (together with payment of interest for
the prior quarter) on the maturity date three years after the Closing Date,





                                       5
<PAGE>   10
and shall be in the form attached as EXHIBIT 2(a)(ii) (the "Promissory Note");
and

                                  (iii)    Such Annual Earnout described in
subparagraph 2(b) thereof as may be payable on the dates and in accordance with
the terms specified in subparagraph 2(c) hereof.

                 (b)      With respect to the period of five (5) years
commencing on December 1, 1996 (the "Earnout Commencement Date"), Buyer shall
pay to Sellers and Sellers will be entitled to receive from Buyer, subject to
the payment provisions of paragraph 2(c), twenty percent (20%) of the annual
Cash Flow of each Contract (as defined in paragraph 2(e) hereof) (the "Annual
Earnout").

                 (c)      The Annual Earnout and Annual Net Revenue Target (as
defined in paragraph 2(e) hereof) shall be calculated on an accrual basis for
each annual period (each an "Annual Earnout Period") within ninety (90) days
after the end of each year after the Earnout Commencement Date for five (5)
years (each an "Annual Calculation Date") subject to the Final Cash Basis
Adjustment, if any, as described in paragraph 2(c)(v) hereof; provided,
however, that the Annual Earnout shall only be payable to Sellers as follows:

                          (i)  On each Annual Calculation Date Buyer will
provide Seller Parent with detailed reports and calculations of the Annual Net
Revenue Target, Cash Flow of each Contract and Annual Earnout for the preceding
Annual Earnout Period, determined through the end of such Annual Earnout
Period, together with a certification by the Chief Financial Officer of Buyer
Parent of the





                                       6
<PAGE>   11
completeness and accuracy of such calculations in accordance with the terms of
this Agreement.  Seller Parent shall have the right to audit the records that
support all such detailed reports and calculations by Buyer, in accordance with
the provisions of subparagraph 2(g) hereof.

                          (ii)  Within fifteen (15) days after the end of each
Annual Calculation Date and each quarterly period after the first Annual
Earnout Period (the "Quarterly Reporting Date") until the seventy-eighth month
after the Earnout Commencement Date, Buyer shall provide Seller Parent with:
(a) a detailed report of all collections received by Buyer during the preceding
Annual Earnout Period (in the case of reports to be provided on an Annual
Calculation Date) or the quarterly period ended on the last day of the month
preceding such Quarterly Reporting Date (in the case of reports to be provided
on a Quarterly Reporting Date) with respect to all Contract Net Revenues for
each preceding Annual Earnout Period, designating the Annual Earnout Period to
which such collections apply; and (b) a detailed report and calculation of the
Current Revenue Collection Percentage (as defined in subparagraph 2(e) hereof)
for each preceding Annual Earnout Period.  Seller Parent shall have the right
to audit the records that support the detailed report and calculation of each
Current Revenue Collection Percentage, in accordance with the provisions of
subparagraph 2(g) hereof.

                          (iii)  On each Annual Calculation Date and Quarterly
Reporting Date, Buyer shall pay to Sellers the sum of the products





                                       7
<PAGE>   12
for all Annual Earnout Periods of:  (a) the Annual Earnout for each such Annual
Earnout Period; multiplied by (b) the Current Revenue Collection Percentage for
each such Annual Earnout Period; provided, however, that such payments shall be
reduced by the amounts of the Annual Earnout previously paid with respect to
each Annual Earnout Period.

                                  (iv)  On each Annual Calculation Date and
Quarterly Reporting Date, as of which the Current Revenue Collection Percentage
for any Annual Earnout Period exceeds 100%, Buyer shall also pay to Seller (in
addition to the amounts referred to above), 20% of the amounts by which the
Contract Net Revenues actually collected exceed the Annual Net Revenue Target
for such Annual Earnout Period.

                                  (v)  On each Quarterly Reporting Date which
coincides with the fifteen month anniversary of the Annual Calculation Date for
each Annual Earnout Period, if the Current Revenue Collection Percentage for
such Annual Earnout Period is then less than 100%, Buyer shall recalculate the
Cash Flow of Each Contract and Annual Earnout for such Annual Earnout Period by
substituting in the formulas thereof, for the applicable Base Bad Debt Reserve
Percentage, the actual Cash Basis Bad Debt Reserve Percentage determined in a
manner consistent with the methodology discussed on EXHIBIT 2(c)(v) (the "Final
Cash Basis Adjustment").  Within 30 days after Seller receives detailed
calculations of the Final Cash Basis Adjustment, for any Annual Earnout Period
(subject to Sellers' rights to audit such information as described below)





                                       8
<PAGE>   13
Sellers shall refund to Buyer the aggregate amounts by which: (x) the
cumulative cash payments received by the Seller applicable to the Annual
Earnout for such Annual Earnout Period calculated on an accrual basis pursuant
to paragraph 2(b) and 2(e)(iii) hereof; exceeds (y) the Annual Earnout
calculated in the Final Cash Basis Adjustment.

                 (d)      The Cash Flow of each Contract during each Annual
Earnout Period will be determined separately and not cumulatively with other
Facility Contracts or other Annual Earnout Periods for purposes of calculating
any Annual Earnout.  If there is Cash Flow for any Facility Contract in any
such Annual Earnout Period, calculation of the Annual Earnout for such Annual
Earnout Period shall be due for such Facility Contract for such period and
shall not be affected by any net loss on any other Facility Contract, whether
in the same or any other Annual Earnout Period.  Sellers shall not be obligated
to return any payment on account of an Annual Earnout in the event of any net
loss incurred under any Facility Contract with respect to any Annual Earnout
Period after such payment is made.

                 (e)      As used herein, the following terms have the
following meanings:

                                  (i)  "Annual Net Revenue Target" shall mean
(for such Annual Earnout Period) the amount of the Contract Net Revenues (as
defined in paragraph 2(e)(vii) hereof) from all Facility Contracts during such
Annual Earnout Period; minus a reasonably projected bad debt reserve for such
Contract Net Revenues, not to





                                       9
<PAGE>   14
exceed 10% thereof for the first two Annual Earnout Periods (the "Base Bad Debt
Reserve Percentage").  Collections in excess of the Annual Net Revenue Target
for each respective Annual Earnout Period will result in additional payments by
Buyer to Seller as provided in paragraph 2(c)(iv) hereof, and the Base Bad Debt
Reserve Percentage for the final three Annual Earnout Periods may be adjusted
as of the third Annual Calculation Date, by applying the methodology described
on Exhibit 2(c)(v) hereto, to the actual collection experience for the first
Annual Earnout Period.  In the event the Base Bad Debt Reserve Percentage for
any Annual Earnout Period is increased pursuant to the Final Cash Basis
Adjustment outlined in paragraph 2(c)(v), then paragraph 2(c)(iv) will apply to
all collections received thereafter for the Net Contract Revenues of such
Annual Earnout Period.

                                  (ii) "Aggregate Regional Overhead Costs"
shall mean reasonable and ordinary costs directly incurred by the Buyer in
connection with the operations of Buyer in Massachusetts (which are
substantially similar in nature, scope and category to the costs reflected in
Buyer's general ledger which were used to make the estimate of a Regional
Allocation for the period ended November 30, 1997, as set forth in EXHIBIT
2(e)(ii));

                                  (iii)    "Cash Flow of each Contract" shall
mean the Contract Net Revenues for each Facility Contract minus (a) the direct
costs of providing such services, which shall be estimated by multiplying the
Contract Net Revenues for such Facility Contract by the Contract Cost
Percentage; (b) a reserve for bad debts which





                                       10
<PAGE>   15
will not exceed the applicable Base Bad Debt Reserve Percentage; (c) amounts
reasonably charged against revenues as refunds made with respect to payments
previously received by Buyer for services rendered pursuant to such Facility
Contract (the "Refunds"); and (d) an allocation of regional overhead to such
Facility Contract (the "Regional Allocation"), initially in the amount of
$7,000 for each separate nursing facility, adult day care center or assisted
living facility (i.e., related facilities on the same "campus" shall be
considered a single "facility" for such purpose) covered by a Facility Contract
(a "Business Facility") for the first Annual Earnout Period.

         (w)  For the first Annual Earnout Period only, the Regional Allocation
for each Business Facility may be increased above $7,000 by an amount
determined by taking 50% of the aggregate sum of the negative Cash Flow of each
Contract derived from the 15 Facility Contracts listed on EXHIBIT 2(e)(iii) for
the first Annual Earnout Period but not to exceed $100,000 in any event (the
"Unabsorbed Regional Overhead") and then dividing the resulting amount by the
total number of Business Facilities under contract to Buyer for the provision
of mobile geripsych management services that yielded a positive Cash Flow of
each Contract for the first Annual Earnout period.

         (x) For each Annual Earnout Period after the first Annual Earnout
Period, such Regional Allocation for each Business Facility shall be made by
multiplying the Aggregate Regional Overhead Costs for such Annual Earnout
Period by the ratio of the Total Net





                                       11
<PAGE>   16
Revenues to the total revenues of Buyer arising from its operations in
Massachusetts and dividing the resulting product by the total number of skilled
nursing facilities, adult day care centers and assisted living facilities in
Massachusetts under contract to Buyer for the provision of mobile geripsych
management services (each, a "Facility") (with any such Facility under contract
for less than the entire year to be counted in such total number based on the
fraction of the year for which such Facility was under contract); provided,
however, that for each Annual Earnout Period after the first Annual Earnout
Period, any proposed Regional Allocation for a Business Facility exceeding
$7,700 shall require the consent of Seller Parent, which consent shall not be
unreasonably withheld; and provided, further, that the Regional Allocation
shall in no event exceed $10,000 for each Business Facility for any Annual
Earnout Period.

         (y) In reporting any proposed change in the Regional Allocation, Buyer
shall provide Seller Parent with a detailed report which compares each category
of expense and the allocation thereof by Facility for the preceding Annual
Earnout Period, to the same category of expense and the allocation thereof for
the Annual Earnout Period for which such change is proposed.  Seller Parent
shall have the right to audit the records that support the detailed report and
calculation of any proposed change in the Regional Allocation.  In the event
that Seller Parent withholds its consent to any proposed increase of the
Regional Allocation allocable to a Facility above $7,700 for more than thirty
(30) days after receipt





                                       12
<PAGE>   17
of such detailed report and calculation, Seller Parent shall be deemed to have
given written notice to Buyer pursuant to subparagraph 2(g) hereof of its
election to exercise its right to audit the records supporting such detailed
report and calculation, and the dispute as to the proposed increase shall be
resolved in accordance with the procedures established in paragraph 2(g)
hereof.

         (z) In calculating the "Cash Flow of each Contract," no deductions
from net revenues shall be made for interest, bad debts, depreciation,
amortization, corporate overhead or regional overhead (except for the Regional
Allocation and bad debt reserves expressly referred to hereinabove).

                                  (iv)  "Contract Cost Percentage" as used
herein shall mean (a) all direct costs incurred for professional mental
healthcare services directly related to the Business, including, without
limitation, salaries, fringe benefits, FICA, reasonable and ordinary payments
for services rendered pursuant to independent contract arrangements with a
professional, any insurance (including professional liability insurance)
covering professionals providing services under all of the Facility Contracts,
and reasonable ordinary and necessary business expenses, including, without
limitation, travel expenses (if reimbursed or paid by Buyer) incurred by any
professionals for such services divided by (b) the total Contract Net Revenues
for all Facility Contracts.

                                  (v)  "Current Revenue Collection Percentage"
shall mean, for each Annual Earnout Period preceding any Annual





                                       13
<PAGE>   18
Calculation Date or Quarterly Reporting Date referred to above, the percentage
(which may exceed 100%) of the Annual Net Revenue Target for such Annual
Earnout Period which has actually been collected as of the end of the Annual
Earnout Period or quarterly period, as the case may be, immediately preceding
such Annual Calculation Date or Quarterly Reporting Date, as the case may be,
with respect to the Contract Net Revenues generated during such Annual Earnout
Period.

                                  (vi) "Sun Contract" shall mean the Geripsych
Consulting Agreement dated as of October 1, 1995 between Seller Parent and
Seller Sub, on the one hand, and Sun Healthcare Group, Inc. and Sunrise
Healthcare Corporation (collectively, the "Sun Parties"), on the other hand.

                                  (vii)    "Contract Net Revenues" as used
herein shall mean gross revenues billed for services pursuant to each Facility
Contract, minus adjustments to reduce these revenues by provisions for discount
arrangements with commercial payers and other contractual or administrative
allowances with government payors.  The differences between established billing
rates and amounts estimated to be received under such discount, contractual and
administrative arrangements are accounted for as "contractual adjustments".

                 (f)      The Purchase Price shall be allocated as follows:

                                  (i)  Five Thousand Dollars ($5,000.00) to the
restrictive covenant set forth in paragraph 13; and

                                  (ii) the balance of the Purchase Price to the
purchase of the Assets that are intangible.





                                       14
<PAGE>   19
                 (g)      Seller Parent may exercise its right to audit
detailed reports and calculations pursuant to paragraphs 2(c)(i), (ii) and (v),
and 2(e)(iii) hereof only in accordance with the procedures set out in this
paragraph.  Seller Parent shall give written notice to Buyer within thirty (30)
days after receipt of a detailed report and calculation of its election to
exercise its right to audit the supporting records.  If Seller Parent so
elects, it shall retain an accounting firm at its expense to conduct such audit
(or it may conduct such audit with representatives of the Seller Parent) and
shall provide a copy of the determination of such accounting firm or such
representatives (the "Seller Determination") to Buyer within thirty (30) days
after delivery of its written notice of election to Buyer.  Buyer and Buyer
Parent shall provide such accounting firm or representatives with reasonable
access and cooperation with regard to the files and materials relevant to such
audit in order to facilitate and expedite such audit, including making
available in Massachusetts, at the expense of Sellers, copies of documents
maintained outside of Massachusetts, provided that such accounting firm or
representatives identify such documents with reasonable specificity.  Seller
Parent shall take such measures to maintain the confidentiality of any
information obtained in any audit as it takes to maintain the confidentiality
of its own confidential information, and all such information will be destroyed
or returned to Buyer promptly after the conclusion of the audit, or in the
event of an arbitration, the issuance of an arbitration award.  In





                                       15
<PAGE>   20
the event there is a discrepancy between Buyer's detailed report and
calculation and the Seller Determination, and the parties hereto do not reach
an agreement on any adjustments to Buyer's detailed report and calculation
within twenty (20) days following Buyer's receipt of a copy of the Seller
Determination, then the matter shall be submitted to binding arbitration in
Boston, Massachusetts, before a single arbitrator who is a Certified Public
Accountant, in accordance with the commercial arbitration rules of the American
Arbitration Association ("AAA").  If the parties fail to agree on the selection
of an arbitrator within ten (10) days after the expiration of the
above-described twenty (20) day period, then the AAA shall promptly make the
selection, which decision shall be binding upon the parties.  The disputed
issues shall be submitted to the arbitrator within five (5) days after
selection of the arbitrator and each issue shall be decided by the arbitrator
within thirty (30) days. The fees and expenses of the AAA and the arbitrator
shall be paid by the parties hereto in proportion to the dollar amount of the
disputed issues decided against each party.  Judgment may be entered on any
decision rendered by the arbitrator, including the fees and expenses of the AAA
and the arbitrator.

         3.      REPRESENTATIONS AND WARRANTIES OF SELLERS

                 Sellers jointly and severally represent and warrant, upon
which representations and warranties Buyer relies, and which representations
and warranties shall survive Closing for the period set forth in paragraph 14
hereinafter, as follows:

                 (a)      Each Seller is a corporation duly organized, validly





                                       16
<PAGE>   21
existing, and in good standing under the laws of its state of incorporation,
and has all requisite power and authority to own the Assets and carry on the
Business as it is now being conducted and to enter into this Agreement and to
consummate the transactions contemplated hereunder.  The Articles of
Incorporation and all amendments thereto to date of Sellers and their Bylaws as
amended to date, all of which have been delivered to Buyer for review prior to
execution of this Agreement, are full, complete and correct to the date of this
Agreement.  Sellers are not in violation of any of the provisions of their
Articles of Incorporation, as amended, nor of their Bylaws as amended.

                 (b)      Sellers have delivered to Buyer unaudited compiled
financial information for the Business for the period(s) ending August 31, 1996
(the "Financial Information").  The Financial Information has been derived from
the books and records of Sellers, and in management's opinion fairly represents
the results of the operation of the Business for the periods presented in all
material respects, except as otherwise noted in the Financial Information.  The
preparation of the Financial Information required management to make estimates
and assumptions that affect the reported amounts of revenues and expenses
during the reported periods.  Actual results could differ from those estimates.

                 (c)      Since August 31, 1996 except as described on EXHIBIT
3(c) attached hereto and made a part hereof, there has not been (i) any
material change, or any material development, or the incurring of any material
liability which has affected in a





                                       17
<PAGE>   22
materially adverse manner the Assets or the Business other than in the ordinary
course of business; or (ii) any modification affecting the term or economics or
termination of any Facility Contract, or failure to renew or extend any
Facility Contract (except in the ordinary course of business).

                 (d)      Sellers own and have good and marketable title to all
the Assets, except, in the case of contractual rights, subject to the consent
of the other contracting party or parties before a transfer of such rights may
occur.  Except as described on EXHIBIT 3(d) attached hereto and made a part
hereof, the Assets are not subject to any security interest, mortgage, deed of
trust, pledge, lien, encumbrance, option, or restriction or limitation on their
transferability (collectively, "Encumbrances"), and none of the Assets is
subject to any commitment or other arrangement for their sale or use by any
affiliate of Sellers or by any third party.

                 (e)      Copies of all Facility Contracts have been delivered
to Buyer (or copies of the form of agreement have been delivered to Buyer and
access to the original, individual contracts has been granted to Buyer) and are
true and complete in all respects material to the term and economics thereof
(except for the copy of the Sun Contract, which is true and complete in all
respects).  Sellers have substantially complied in all respects with all of the
provisions of all Facility Contracts, and are not in breach, violation or
default under any of them.  No event has occurred with respect to the Sun
Contract that constitutes, or with the lapse of





                                       18
<PAGE>   23
time or the giving of notice, or both, would constitute a breach, violation or
default under the Sun Contract that would permit the Sun Parties to terminate
the Sun Contract, or to recover damages or otherwise avail themselves of a
legal or equitable remedy thereunder, except as described on EXHIBIT 3(e).

                 (f)      Except for those matters disclosed on EXHIBIT 3(f)
attached hereto and made part hereof, there is no action, suit, litigation,
claim, administrative, state, federal or local, or governmental or
quasi-governmental investigation or proceeding pending or, to the best of
Sellers' knowledge, threatened against Seller relating to the Business or the
Assets.  Sellers are not party to, or the subject of, any action, suit,
litigation, claim, administrative proceeding or governmental or
quasi-governmental investigation relating to the Business or the Assets; nor to
the best of the knowledge of Sellers is any such action, suit, litigation,
proceeding or investigation threatened.  Sellers are not subject to any order,
judgment, decree or obligation which would limit their ability to operate the
Business in the ordinary course or enter into this Agreement and consummate the
transactions contemplated hereby.

                 (g)      This Agreement does not violate any existing statute,
law, regulation, rule, court or administrative judgment, order or decree which
is applicable to Sellers or the Assets or the Business, or to which Sellers are
subject or by which Sellers are bound, or Sellers' Articles of Incorporation or
Bylaws.  Except as set forth in EXHIBIT 3(g) attached hereto and made a part
hereof,





                                       19
<PAGE>   24
all actions of Sellers necessary to authorize Sellers to execute, deliver and
consummate this Agreement have been duly and validly authorized and taken; no
further actions or authorizations are required; and this Agreement constitutes
the valid, legally binding obligation of Sellers and is enforceable in
accordance with its terms, except as the enforceability may be limited by
bankruptcy, insolvency, or other similar laws affecting the enforcement of
creditors' rights generally, and further except to the extent that the
enforceability of such obligations is subject to general principles of equity
(regardless of whether such enforceability is considered in a proceeding in
equity or at law).  This Agreement and the transactions contemplated herein
will not constitute a violation or breach of, or be in conflict with, or
constitute a default under the terms of, or require the consent not heretofore
obtained of any person under, any contract (other than the Facility Contracts),
agreement, equipment lease or other instrument to which Sellers or are subject,
or are parties, or are bound.

                 (h)      No Seller has received any notice of any pending or
threatened claim, investigation, or inquiry by any governmental or
quasi-governmental authority asserting that any Seller has at any time engaged
in any unlawful activity in the operation of the Business, except as noted on
EXHIBIT 3(h) hereto.

                 (i)      (i)To the best of Sellers' knowledge, except as set
forth in EXHIBIT 3(i)(i) Sellers have complied in all material respects with,
and are currently in compliance with, all existing statutes, laws, ordinances,
rules, regulations, judgments, decrees





                                       20
<PAGE>   25
and orders, of any court or governmental or quasi-governmental authority, to
which the Business (or Sellers with respect to the Business) is subject or by
which either is bound and non-compliance with which could adversely affect the
Business in any material respect.

                                  (ii) No Seller has executed any contracts or
agreements with any governmental authority or person expressly providing that
the Business shall provide a certain amount of free care.

                 (j)      Except as described on EXHIBIT 3(j) attached hereto
and made part hereof:

                                  (i)  To the actual knowledge of Sellers, no
employees of the Business are represented by any labor organization with
respect to their employment in the Business and, as of the date hereof, no
labor organization or group of such employees of the Business has made a demand
to any Seller for recognition or has filed a petition with any Seller seeking a
representation proceeding or given Sellers notice of any intention to hold an
election of a collective bargaining representative.  To the actual knowledge of
Sellers, there is no strike, work stoppage, or labor disturbance pending or
threatened which involves any such employee of the Business; and

                                  (ii) To the actual knowledge of Sellers,
there are no unfair employment or labor practice charges or employment-related
litigation or administrative proceedings which are presently pending against
any Seller in relation to employees





                                       21
<PAGE>   26
of the Business.

                 (k)      No Seller, or any officer, director or employee, or
any agent with actual authority, of any Seller has at any time made gifts,
gratuities, or payments in any other form, whether in cash, goods or services,
to any persons or entities whatsoever, in payment for, or intended to induce or
encourage, or which resulted in or may have resulted in or had the effect of
inducing, obtaining, encouraging or continuing the referral of persons or
entities as customers for the Business, or inducing, obtaining, encouraging or
extending any contractual relationship, written or oral with respect to the
Business, in violation of any law; nor has any Seller or any officer, director,
employee, member or agent thereof (i) entered into any arrangement, written or
oral, under or pursuant to which bribes, kickbacks, rebates, payoffs or other
forms of illegal payments or remuneration have been or will be made, provided
for, or offered, either directly or indirectly with respect to the Business
through agents with actual authority, brokers, distributors, dealers or other
intermediaries, or (ii) made any illegal contribution of monies, services or
property to any political party, candidate or elected official for any purpose.

                 (l)      There is no material fact about the Assets or the
Business or Sellers as of the Closing Date known to Sellers which Sellers have
not disclosed in this Agreement or in any Exhibit hereto which materially and
adversely affects or may reasonably be expected to affect, materially and
adversely, the Assets or the





                                       22
<PAGE>   27
Business as of the Closing Date.  Sellers make no warranties, representations
or covenants whatsoever regarding the prospects, projections, operations or
earnings, assets, liabilities or condition (financial or otherwise) of the
Assets or the Business after the Closing Date.

         Buyer and Buyer Parent acknowledge that all of the Facility Contracts,
other than the Sun Contract, can be terminated without cause on relatively
short periods of time, generally 30 to 60 days.  In addition, Buyer and Buyer
Parent acknowledge that Sellers do not have certain licenses which Buyer has in
Massachusetts which will allow the Buyer to run the Business in a more
efficient manner.  Sellers acknowledge that the Business has not been
profitable prior to the date hereof.  Buyer and Buyer Parent acknowledge that
the success or failure of the Business on a going forward basis will depend
largely on the Buyer's handling of the Facility Contracts in the future.
Notwithstanding anything to the contrary contained herein Sellers make no
representations, warranties or covenants as to the survival of any Facility
Contract after the Closing or as to the assignability of any of the Facility
Contracts.

         4.      REPRESENTATIONS AND WARRANTIES OF BUYER

                 Buyer represents and warrants to Sellers, upon which
representations and warranties Sellers rely, and which representations and
warranties shall survive Closing for the period set forth in paragraph 14
hereinafter, as follows:

                 (a)      Buyer is a corporation duly organized, validly
existing and in good standing under the laws of the State of





                                       23
<PAGE>   28
Delaware, and has all requisite power and authority (corporate and other) to
enter into this Agreement and to consummate the transactions contemplated
hereby.

                 (b)      The execution and delivery of this Agreement and the
consummation of the transactions contemplated hereunder by Buyer have been duly
and validly authorized and no further actions or authorizations are required;
and this Agreement has been duly executed and delivered by Buyer and
constitutes the valid, legally binding obligation of Buyer in accordance with
its terms, except as enforceability may be limited by bankruptcy, insolvency,
or other similar laws affecting the enforcement of creditors' rights generally,
and further except to the extent that the enforceability of such obligations is
subject to general principles of equity (regardless of whether such
enforceability is considered in a proceeding in equity or at law);

                 (c)      The execution and delivery of this Agreement and the
consummation of the transactions contemplated by this Agreement will not:

                                  (i)  Result in any breach of, or constitute a
default under, the Certificate of Incorporation or Bylaws of Buyer, or any
contract, agreement, instrument or obligation to which either Buyer or Buyer
parent is a party or to which either of them is subject or by which either of
them is bound, or;

                                  (ii) Violate any existing statute, law,
regulation, rule, court or administrative judgment, order, or decree applicable

                                       24
<PAGE>   29
is bound.

                 (d)      Buyer has or will have by the Closing Date all
licenses and approvals necessary to conduct the Business after the Closing
Date.  Buyer represents that it has adequate financial resources available to
it from Buyer Parent to finance the working capital needs of the Business after
the Closing Date as evidenced by copies of the most recent financial statements
for Buyer Parent filed with the Securities and Exchange Commission, copies of
which are attached hereto as EXHIBIT 4(d).  Buyer is not subject to any order,
judgment, decree or obligation which would limit its ability to operate the
Business in the ordinary course after the Closing or enter into this Agreement
and consummate the transactions contemplated hereby.  Buyer has not received
any notice of any pending or threatened claim, investigation, or inquiry by any

generally consistent in all material respects with prior practice.

                 (d)      Except in the ordinary course of business, not to

warranties made in this Agreement by Sellers to be materially untrue or
incorrect in any adverse respect on and as of the Closing Date with the same
force and effect as if such representations and warranties had been made on and
as of the Closing Date.

                 (e)      During the period from the date of this Agreement to

and other representatives ("Buyer's Representatives"), reasonable access upon
prior notice to the offices, records, files and books of account of Sellers for

consummated, Buyer and its representatives shall, upon request of Sellers,
return to Sellers all copies made by Buyer and its representatives of material
belonging to Sellers and shall destroy all such confidential information
contained in any document of Buyer.

                 (f)      To maintain Sellers as corporations in good standing





                                       29

of each other state in which they are qualified to do business.

release to be made on behalf of Sellers.

required), by a date early enough to allow the transactions to be consummated
by the Document Closing and effective as of the Closing Date except as
otherwise agreed in writing by the parties hereto.

                                  (i)  Any breach of any warranty or
representation made by Sellers in this Agreement or any Exhibit hereto or in
any certificate or document delivered pursuant to this Agreement;

                                  (ii) Any loss or damage resulting to Buyer or
Buyer Parent by reason of any claim, debt, liability or obligation of Sellers,
except for liabilities or obligations of Sellers expressly assumed by Buyer
pursuant to the provisions of subparagraph 1(c) of this Agreement; and

                                  (iii)    All liabilities and obligations,

                 Without restricting the generality of the foregoing, Sellers
hereby agree to indemnify Buyer and Buyer Parent and save and hold them

<PAGE>   42
                 (b)      Buyer hereby agrees to indemnify Sellers and save and

                                       38
<PAGE>   43
                 (c)      Any party, whether Buyer or Seller, claiming a right
to indemnification under the provisions of this paragraph 9 (hereinafter, the
"Indemnitee") shall give written notice as promptly as practicable (and in any
event, within ten (10) days after receipt of notice or service of any citation,
Summons, Complaint or lawsuit) to the other parties of each claim for
indemnification hereunder, specifying the amount and nature of the claim, and
of any matter which, in the opinion of the claiming party, is likely to give
rise to an indemnification claim.  Notwithstanding the foregoing, the failure
to give timely notice shall not affect rights to indemnification hereunder,
except to the extent that the party or parties against whom such indemnity is
sought to be recovered (hereinafter, the "Indemnitor") shall demonstrate damage
caused by such failure. Indemnitor shall have the right to undertake the
defense of any such matter at Indemnitor's sole cost and expense, and through
legal counsel reasonably acceptable to Indemnitee, provided that Indemnitor
proceeds in good faith, expeditiously and diligently.  No final determination
shall be made pursuant to subparagraph 9(d) below while such defense is still
being made until the earlier of (x) the resolution of such claim by Indemnitor
with the claimant, or (y) the termination of the defense by Indemnitor against
such claim or the failure of Indemnitor to prosecute such defense in good faith
and in an expeditious and diligent manner. Indemnitee, at its option and at its
sole cost and expense, shall have the right to participate in any defense
undertaken by Indemnitor, with legal





                                       39
<PAGE>   44
counsel of its own selection.  No settlement or compromise may be made by
Indemnitor without the prior written consent of Indemnitee unless (x) prior to
such settlement or compromise Indemnitor acknowledges in writing Indemnitor's
obligation to pay in full the amount of the settlement or compromise and all
associated expenses; (y) Indemnitee is furnished with security reasonably
satisfactory to Indemnitee that Indemnitor will in fact pay such amount and
expenses; and (z) if any part of the settlement or compromise establishes an
obligation other than payment and the making of customary releases and filings,
the Indemnitee is not required to fulfill any such obligation.

                 (d)      Indemnitor shall pay to Indemnitee the amount of
established claims for indemnification within twenty (20) days after the
establishment thereof by final judgment thereon after all appeals have been
taken or applicable appeal periods have expired (the "Due Date") in cash or by
certified check.  Any amounts not paid by Indemnitor on or before the Due Date
shall bear interest from the Due Date thereof (if and when Indemnitee pays
same) until the date paid at a rate equal to the prime rate of interest as
published in the Wall Street Journal under "Money Rates" from time to time or,
if such a rate is no longer published by the Wall Street Journal, the rate most
comparable to the prime rate.

                 (e)      The indemnifications provided in this paragraph 9
shall survive Closing, provided that any claim for indemnification hereunder
shall be made no later than two (2) years after Closing.

                 (f)      Notwithstanding anything to the contrary contained





                                       40
<PAGE>   45
herein, no indemnity shall be payable by Buyer or Sellers hereunder with
respect to claims until the amount of all claims of the Indemnitee pursuant to
this paragraph 9 shall exceed $25,000.00 in the aggregate and any indemnity
payable hereunder with respect to such claims shall be limited to the excess of
the amount of all claims over $25,000, provided that such indemnity shall be
payable only in respect of claims of $5,000 or more.  Notwithstanding anything
to the contrary contained herein, the aggregate maximum indemnity obligation
payable by Sellers shall in no event exceed the aggregate amounts paid to
Sellers by the Buyer and Buyer Parent under this Agreement; provided, however,
that in the event that Buyer does not use "Bay Colony" in its name, and only in
such event, the foregoing maximum shall be increased by $300,000 only with
respect to any indemnity obligation payable by Sellers due to a breach of
paragraphs 3(f) (but only with respect to a claim based on an action, suit,
litigation, claim, or investigation by a governmental entity or an order,
judgment, decree, or obligation obtained by a governmental entity), 3(h), and
3(k) asserted prior to the first anniversary of the Closing Date.

         10.     CLOSING

                 The Document Closing shall take place on November 22, 1996

                 Sellers shall deliver to Buyer and Buyer Parent at the
Document Closing an opinion of Seller Parent's General Counsel, in form and
substance reasonably acceptable to Buyer's counsel, dated as of the date of the
Document Closing, addressed to Buyer and Buyer Parent, to the effect that:

                 (a)      Each Seller is a corporation duly organized, validly
existing and in good standing under the laws of its state of incorporation,
with full corporate power to carry on its business as it is being conducted.

                 (b)      The execution, delivery and performance of this
Agreement and all documents and agreements required to be executed by Sellers
by this Agreement have been duly authorized and approved by all necessary
corporate and other required action, and neither the execution, delivery or

actions or authorizations, and constitute their respective legal, valid and
binding obligations, enforceable in accordance with their respective terms,
except as the enforceability of all such documents and agreements may be
limited by bankruptcy, insolvency, or other similar laws affecting the
enforcement of creditors'





                                       43
<PAGE>   48
rights generally, and further except to the extent that the enforceability of
such obligations is subject to general principles of equity (regardless of
whether such enforceability is considered in a proceeding in equity or at law).

         12.     OPINION OF COUNSEL FOR BUYER

                 Buyer shall deliver to Sellers at the Document Closing an
opinion of Simon, Turnbull & Martin, Chartered, counsel for Buyer and Buyer
Parent, in form and substance reasonably acceptable to Seller's counsel, dated
as of the date of the Document Closing, addressed to Sellers, to the effect
that:

                 (a)      Each of Buyer and Buyer Parent is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Delaware, with full corporate power to carry on its business as it is being
conducted.

                 (b)      The execution, delivery and performance of this
Agreement and all documents and agreements required to be executed by Buyer and
Buyer Parent by this Agreement have been duly authorized and approved by all
necessary corporate and other required action, and neither the execution,
delivery or performance of, or consummation of the transactions contemplated
by, this Agreement by Buyer and Buyer Parent require any further actions or
authorizations.  This Agreement and all such documents and agreements delivered
pursuant to this Agreement have been duly executed and delivered by Buyer and
Buyer Parent, require no further actions or authorizations, and constitute
their respective legal, valid and binding obligations, enforceable in
accordance





                                       44
<PAGE>   49
with their respective terms, except as the enforceability of all such documents
and agreements may be limited by bankruptcy, insolvency, or other similar laws
affecting the enforcement of creditors' rights generally, and further except to
the extent that the enforceability of such obligations is subject to general
principles of equity (regardless of whether such enforceability is considered
in a proceeding in equity or at law).

         13.     RESTRICTIVE COVENANT

                 (a)      The parties understand and agree that it is the
intention of Buyer to expand markets and marketing activities, utilizing the
Assets, beyond those engaged in by Sellers; and further that such operations
are intended in the future to be throughout the Commonwealth of Massachusetts.
Therefore, Sellers agree that for a period of three (3) years from and after
Closing hereunder, no Sellers will, directly or indirectly, within the
Commonwealth of Massachusetts, carry on or engage in, whether by owning an
interest in, leasing, managing, operating, providing services to, or otherwise,
any business which shall provide mobile professional geripsych services to
residents of or geripsych management services to, skilled nursing facilities,
adult day care centers, and assisted living facilities or counseling services
to, or management of counseling services for, residents' families in any of the
foregoing facilities (which counseling services are currently billed under
Medicare Procedure Codes 90846 and 90847), or any similar business with respect
to residents of such facilities.





                                       45
<PAGE>   50
                 (b)      Sellers acknowledge that the restrictions contained
in subparagraph 13(a), in view of the nature of the business activities in
which Buyer intends to utilize the Assets, are reasonable and necessary in
order to protect the legitimate interests of Buyer, and that any violation
thereof would result in irreparable injuries to Buyer.  Sellers therefore
acknowledges that in the event of a breach or threatened breach of the
provisions of subparagraph 13(a) by Seller, Buyer shall be entitled to obtain
from any court of competent jurisdiction, preliminary and permanent injunctive
relief restraining Sellers from any violation of the foregoing, provided that
Buyer shall not be entitled to an injunction contrary to the public health,
safety or welfare.  If the period of time or geographic area specified should
be deemed unreasonable in any proceeding, then the period of time or geographic
area will be reduced by the elimination or reduction of a portion thereof so
that such restrictions may be enforced for such time and area as is adjudged to
be reasonable.

                 (c)      Nothing herein shall be construed as prohibiting
Buyer from pursuing any other remedies available to it for such breach or
threatened breach, including recovery of damages and an equitable accounting of
all earnings, profits and other benefits arising from such violation, from
Seller.

         14.     SURVIVAL OF REPRESENTATIONS AND WARRANTIES

                 The parties hereto agree that the representations and
warranties contained in this Agreement and the Exhibits hereto, and in each
certificate, document or instrument delivered in connection





                                       46
<PAGE>   51
herewith, shall survive the execution and delivery of this Agreement and the
Closing hereunder, regardless of any investigation made by any of the parties
hereto; and shall continue to exist as to each such representation and warranty
for a period of two (2) years from and after Closing.

         15.     FURTHER ASSURANCES

                 Subsequent to the Document Closing and Closing, Seller and
Buyer shall each, at the reasonable request of the other, furnish, execute and
deliver such documents, instruments, certificates, notices and other and
further assurances as counsel for the requesting party shall reasonably require
as necessary or desirable to effect complete consummation of this Agreement and
to carry out the transactions contemplated hereunder, or in connection with the
preparation and filing of reports (including tax returns and reviews thereof)
required or requested by governmental agencies, stock exchanges or other
regulatory bodies.  Without restricting the generality of the foregoing, Buyer
shall cooperate with and assist Sellers in the collection of accounts
receivable of the Business and the Facility Contracts with respect to periods
prior to the Closing by having its employees respond to questions and requests
regarding such accounts receivable (for no consideration) to the extent such
cooperation and assistance becomes necessary as a result of the transactions
contemplated hereby and Sellers make available to Buyer such patient records as
Buyer may reasonably request in connection with post-closing provision of
services to patients.  If Buyer or either Seller





                                       47
<PAGE>   52
receives funds to which the other party is entitled, such party shall promptly
transfer such funds to such other party.

         16.     TERMINATION

                 This Agreement may be terminated by written notice from either
Buyer or Sellers to the other party if the Document Closing has not occurred on
or before November 22, 1996, without further liability of either party to the
other, except with respect to the confidentiality of materials delivered by
each party to the other.

provisions thereof.  Except as aforesaid, if any one or more of the provisions
contained in this Agreement or in any other instrument referred to herein
shall, for any reason, be held to be invalid, illegal or unenforceable in any
respect, then and in that event, to the maximum extent permitted by law, such

of another party thereto would constitute a breach thereof or in any material

would not in fact receive all such rights, Sellers shall cooperate in any
reasonable arrangement designed to provide the Buyer the benefits under any
such claim, right or contract, including, without limitation, enforcement of
any and all rights of Sellers against the other party or parties thereto
arising out of the breach or cancellation by such other parties or otherwise.

                                 PROMISSORY NOTE

$150,000.00                                                     December 1, 1996


         FOR VALUE RECEIVED, the undersigned MHM Extended Care Services, Inc.,
a Delaware corporation (the "Company"), promises to pay to the order of Liberty
Management Group, Inc., a Massachusetts corporation, and Liberty Bay Colony
Health Services, Inc., a Massachusetts corporation, jointly, (collectively, the
"Payees"), the principal sum of ONE HUNDRED FIFTY THOUSAND DOLLARS ($150,000.00)
in one (1) installment on December 1, 1999, together with interest on the unpaid
balance of this Note from time to time outstanding, at the rate hereinafter set
forth, from the date hereof until payment in full of all principal and interest
hereunder. This Note may be prepaid in whole or in part at any time and from
time to time, without premium or penalty.

         1.     Interest. Interest on the unpaid balance hereof shall be payable
quarterly in arrears on the 1st day of each March, June, September, and
December, commencing March 1, 1997 and shall be at the rate of nine percent (9%)
per annum (computed on the basis of a year of three hundred sixty (360) days for
the actual number of days elapsed). Any payment not made when due and the
entire unpaid balance after default or maturity shall accrue interest at the
rate of eighteen percent (18%) per annum, or, if less, the highest rate
allowable by applicable law.

         2.     Event of Default. Upon the occurrence of any of the following 
events (each hereinafter called an "Event of Default"):

                (a) The Company shall fail to pay any installment of principal
or interest hereunder when due and shall have failed to cure such nonpayment
within five business days after receiving notice from Payees of such failure to
pay; provided, however, that after Payees send such a notice as a result of the
failure of the Company to pay any installment when due, any failure by the
Company to pay when due any other installment due during the twelve months after
the date of the first such notice shall constitute an Event of Default.

                (b) The Company shall fail to cure any breach of this Note
(other than a failure to pay any installment of principal or interest) within
thirty (30) days after receiving notice from Payees of such breach.

                (c) The Company shall fail to pay promptly when due any
indemnity obligation under that certain Asset Purchase Agreement of even date by
and among the Company, MHM Services, Inc. ("MHM"), and Payees.

                (d) The dissolution, termination of existence, insolvency,
business failure, cessation, suspension or termination of the active conduct of
the normal business activities of the Company or MHM; the service upon either
Payee of a writ or other court document in which such Payee is named as trustee
of the Company or MHM, which attachment remains undischarged for a period of 45
days; the calling of a meeting of creditors, appointment of a committee of
creditors or liquidating agents, or offering of a composition or extension to
creditors by, for or of the Company or MHM; the Company or MHM shall make any
assignment for the benefit of creditors, or enter into any composition, trust
mortgage or similar arrangement with its respective creditors; the Company or
MHM shall cease, be unable or admit in writing its inability to pay its
respective debts as they mature; or the commencement by or against the Company
or MHM of a case under the federal bankruptcy laws, as now or hereafter
constituted, or under any other applicable federal or state bankruptcy,
insolvency or other laws relating to relief for debtors, or the readjustment,
reorganization, composition or extension of debt; or

                (e) The entry of a decree or order against, or consent by the
Company or MHM to the appointment of a receiver, liquidator, assignee,
custodian, trustee or sequestrator (or similar official) of the Company or MHM
or for any part of the property of the Company or MHM or the winding up or
liquidation of the affairs of either;

then, and in any such event, and at any time thereafter if any Event of Default
shall then be continuing, the principal of and accrued interest on this Note
shall, at Payees' option, forthwith become, due and payable without presentment,
demand, protest or notice of any kind, all of which are hereby waived by the
Company; provided that, if an Event of Default specified in Section 2(d) shall
occur, the principal of, and accrued interest on, this Note shall automatically
and immediately become due and payable, without presentment, demand, protest or
notice of any kind, all of which are hereby waived by the Company.

         3.     Waivers. The Company hereby (a) waives all presentment, demand
