                          CONTRIBUTIONS TO THE COMPANY,
                       CAPITAL UNITS AND CAPITAL ACCOUNTS

        6.1    CAPITAL CONTRIBUTIONS.

               (a) REQUIRED CAPITAL CONTRIBUTIONS. Each Member shall contribute
within 60 days following the date of this Operating Agreement such amount as is
set forth in Schedule A hereto as such Member's share of the Initial Capital
Contribution and will receive a credit to such Member's Capital Account in the
amount set fort in Schedule A. At the Second Closing (as defined in that certain
Subscription Agreement by and between the Members, dated as of June 8, 1998 (the
"Subscription Agreement")), each Member shall contribute such assets as is set

set forth in Schedule A.

               (b) ADDITIONAL CAPITAL CONTRIBUTIONS. No Member shall be required
to make any additional Capital Contribution to the Company. Members may make
additional Capital Contributions only upon agreement of all Members and, unless
all Members otherwise agree in writing, pro rata in proportion to the Units held
by each Member. Without in any way limiting the generality of the foregoing, no
additional capital contribution shall be required pursuant to an arbitration
under Section 14.1.

               (c) LOANS. In the event that less than all Members agree to make
additional Capital Contributions, any Member shall have the right, but not the
obligation, to make a loan (to the extent funds are reasonably required by the
Company for a bona fide purpose, including for operations or to pay debts or
liabilities) to the Company with interest at the rate of prime plus two percent
(2%), with principal and interest payable not less than quarterly, and on such
other then prevailing commercially reasonable terms.

        6.2 UNITS. Each Member's Interest in the Company shall be represented by
Units of membership interest each having identical rights and privileges. An
unlimited number of Units is hereby authorized. In consideration for their
respective Initial and Second Capital Contributions, the Initial Members shall

        6.3    CAPITAL ACCOUNTS.

               (a) A separate Capital Account will be maintained for each
Member. Each Member's Capital Account will be increased by (1) the amount of
money contributed by such Member to the Company; (2) the fair market value of
property contributed by such Member to the Company (net of liabilities secured
by such contributed property that the Company is considered to assume or take
subject to under Section 752 of the Code); and (3) the amount of Net Profits or
other items of income or gain allocated to such Member. Each Member's Capital



                                       12
<PAGE>   13

Account will be decreased by (1) the amount of money distributed to such Member
by the Company; (2) the fair market value of property distributed to such Member
by the Company (net of liabilities secured by such distributed property that
such Member is considered to assume or take subject to under Section 752 of the
Code); and (3) the amount of Net Losses or other items of deduction or loss
allocated to such Member.

               (b) In the event of a permitted sale or transfer of all or part
of a Member's Interest in the Company, the Capital Account of the transferor
shall become the Capital Account of the transferee to the extent it relates to
the transferred Interest.

               (c) The manner in which Capital Accounts are to be maintained
pursuant to this Section 6.3 is intended, and shall be construed so as, to
comply with the requirements of Code Section 704(b) and the Treasury Regulations
promulgated thereunder.

               (d) Upon liquidation of the Company (or any Member's Interest),
liquidating distributions will be made in accordance with the positive Capital
Account balances of the Members, as determined after taking into account all
Capital Account adjustments for the Company's taxable year during which the
liquidation occurs. Liquidation proceeds will be paid within sixty (60) days of
the end of the taxable year (or, if later, within ninety (90) days after the
date of the liquidation).

        6.4    WITHDRAWAL OR REDUCTION OF MEMBERS, CONTRIBUTIONS TO CAPITAL.

               (a) A Member shall not receive out of the Company Property any
part of its contributions to capital until all liabilities of the Company,
except liabilities to Members on account of their contributions to capital, have
been paid or there remains property of the Company sufficient to pay them.

               (b) A Member shall not be entitled to demand or receive from the
Company the liquidation of its interest in the Company until the Company is
dissolved in accordance with the provisions hereof or other applicable
provisions of the Delaware Act.

                                    ARTICLE 7

          DISTRIBUTIONS, ALLOCATIONS, INCOME TAX, ELECTIONS AND REPORTS

        7.1 DISTRIBUTIONS OF PROFITS AND LOSSES.

               (a) DISTRIBUTION OF PROFITS. Until such time as the total
cumulative Net Income Base (as defined below) amounts paid to Stadtlander
hereunder equals the amount of the Aggregate Net Income Base Obligation (i.e.,
when the Aggregate Net Income Base Obligation is satisfied), the cash available
for distribution shall be distributed as follows: Stadtlander will receive, and
the Company will be obligated to pay (subject to any limitation contained
herein) annually within 30 days following the completion of the annual audit of
the financial results of the Company, Distributable Cash equal to at least the
full amount of the Net Income Base for the Fiscal Year as set forth in this
Section 7.1(a) reduced by the amount of Gross Margin previously paid by Company
to Stadtlander under that certain Transition and Services Agreement dated as of
even date herewith, among Company, PMR and Stadtlander (the "Transition and
Services



                                       13
<PAGE>   14

Agreement"). Any deficit in a Net Income Base distribution shall accrue interest
at the same rate of interest as the senior debt of the Company plus 1% (or if
there is no senior debt outstanding, the Wall Street Journal prime rate plus one
percent (1%)) and subject to Section 7.1(a)(iii) shall be payable with the Net
Income Base Payment for the Fiscal Year ended December 31, 2000 or, at the
Company's option, at any earlier time. Any Distributable Cash in excess of the
Net Income Base shall then be distributed between the Members in accordance with
their Interests. All Distributable Cash shall be distributed between the Members
in accordance with their Interests after the Aggregate Net Income Base
Obligation is satisfied. Notwithstanding anything herein to the contrary, the
Managers shall not make (i) for the Fiscal Year ended December 31, 1998, any
distribution in excess of consolidated net cash flow from operations (determined
in accordance with generally accepted accounting principles consistently applied
("GAAP")), or (ii) for each of the Fiscal Years ended December 31, 1999 and
2000, any distribution in excess of consolidated net cash flow from operations
determined (in accordance with GAAP) as of December 31, 1999 or December 31,
2000, as the case may be, as adjusted for certain capital expenditures to be
agreed upon by the parties.

                      (i) The following terms shall have the definitions set
forth below:

                             (1) "Aggregate Net Income Base Obligation" shall
mean the greater of $48,000,000 or the product of the Net Income Base for the
Fiscal Year ended December 31, 2000 multiplied by ten (10).

                             (2) "Clozaril Base Overhead" shall be the sum of
$5,375,000, which is the Company's estimated operating and overhead expenses for
pharmaceutical fulfillment and case management services during each full Fiscal
Year relating solely to the sales of Clozaril and Clozapine (and any of their
successor products) by the Company, and which is determined as set forth in
Schedule B attached hereto.

                             (3) Subject to the provisions of this subsection
7.1(a)(i)(3), "Clozaril Gross Profit" shall mean for a Fiscal Year, the product
of (i) the average gross profit per patient participating in the Company's
Clozaril and Clozapine (or successor product) program ("Clozaril Customer")
(determined in accordance with GAAP), multiplied by (ii) 6,000. For purposes of
this subsection, so long as there are at least 6,000 Clozaril Customers in the
Initial States (as defined in the Transition and Services Agreement), the
average gross profit described in clause (i) above shall be calculated based
only on the Clozaril Customers in such Initial States. If there are less than
6,000 Clozaril Customers in the Initial States, the Clozaril Gross Profit shall
be calculated using gross profit for the actual number of Clozaril Customers in
the Initial States plus the blended average gross profit per customer for all
other Clozaril Customers multiplied by the difference between the number of
Clozaril Customers in the Initial States and 6,000.

                      (ii) Net Income Base for a Fiscal Year shall be determined
as set forth below:

                             (1) For the Fiscal Year ending December 31, 1998,
the Net Income Base shall be the greater of (A) $2,000,000 or (B) the result of
Clozaril Gross Profit minus fifty percent (50%) of the Clozaril Base Overhead.
In the event the Company begins operations after July 1, 1998, the dollar amount
set forth in (A) and the portion of the Clozaril



                                       14
<PAGE>   15

Base Overhead set forth in (B) shall be pro-rated for the remainder of the
Fiscal Year based on the number of days of operations divided by 180.

                             (2) For the Fiscal Year ending December 31, 1999,
the Net Income Base shall be the greater of (A) $4,000,000 or (B) the result of
Clozaril Gross Profit minus Clozaril Base Overhead.

                             (3) For the Fiscal Year ending December 31, 2000,
the Net Income Base shall be the greater of (A) $4,000,000 or (B) the result of
Clozaril Gross Profit minus Clozaril Base Overhead, and the Net Income Base
distribution shall be accompanied by a payment of all outstanding deficits of
previous Net Income Base distribution obligations (plus accrued interest) as
described in Section 7.1(a).

                             (4) Subject to Section 7.1(a)(iii), for each
subsequent Fiscal Year beginning with the Fiscal Year ending December 31, 2001,
the Net Income Base shall be the greater of (A) $4,000,000 or (B) the amount of
the Net Income Base for the Fiscal Year ended December 31, 2000.

                      (iii) If for the Fiscal Year ended December 31, 2000 (1)
the result of gross profit from all sales of Clozaril and Clozapine (and
successor products) (determined in accordance with GAAP) is less than $4,000,000
and (2) the Company's earnings before interest and taxes (exclusive of any
allocations of corporate overhead or other expenses not in the ordinary course
of business), determined in accordance with GAAP ("EBITDA"), is less than
$7,600,000, then Stadtlander and PMR shall negotiate in good faith and shall
agree to appropriately adjust the amount of the Net Income Base distribution for
each subsequent Fiscal Year downward to an equitable amount and defer the
payment of any accrued deficit of Net Income Base distributions then
outstanding.

               (b) TAX WITHHOLDING. All amounts withheld pursuant to the Code or
any provisions of state or local tax law with respect to any income allocable to
or payment or distribution to the Members from the Company shall be treated as
amounts distributed to the relevant Member or Members pursuant to the applicable
subparagraph of this Section 7.1.

        7.2 ALLOCATIONS OF NET PROFITS AND NET LOSSES. For each Accounting
Period, Net Profits and Net Losses (and, to the extent necessary, items thereof)
shall be allocated as follows:

               (a) First, to Stadtlander until its Adjusted Capital Account
balance is equal to the amount that Stadtlander would have been entitled to
receive pursuant to the first two sentences of Section 7.1(a) had the Company
sold all of its assets as of the end of such Account Period for an amount that
generated no Net Profit or Net Loss (or any other item of income, gain, loss or
deduction) and immediately thereafter distributed all of such assets in
liquidation of the Company pursuant to Section 7.1.

               (b) Second, to all Members in accordance with their Interests.



                                       15
<PAGE>   16

        7.3    SPECIAL ALLOCATIONS.

               (a) LIMITATIONS ON LOSSES ALLOCATIONS. Notwithstanding Section
7.2(b) above, no loss shall be allocated to a Member if such allocation would
cause such Member's Adjusted Capital Account to become negative or to increase
the negative balance thereof.

               (b) QUALIFIED INCOME OFFSET. In the event any Member unexpectedly
receives any adjustments, allocations or distributions described in Section
1.704-l(b)(2)(ii)(d)(4), (5) or (6) of the Treasury Regulations, items of
Company income and gain shall be specially allocated to each such Member in an
amount and manner sufficient to eliminate, to the extent required by the
Treasury Regulations, the deficit balance of the Adjusted Capital Account of
such Member as possible, provided that an allocation pursuant to this Section
7.3(b) shall only be made if and to the extent such Member would have a deficit
balance in its Adjusted Capital Account after all other allocations provided for
in Section 7.2 and Section 7.3 have been made as if this Section 7.3(b) were not
in this Operating Agreement.

               (c) GROSS INCOME ALLOCATION. In the event any Member has a
deficit Capital Account at the end of any Accounting Period which is in excess
of the sum of (i) the amount such Member is obligated to restore pursuant to any
provision of this Operating Agreement, if any, and (ii) the amount such Member
is deemed to be obligated to restore pursuant to the penultimate sentence of
Treasury Regulations Sections l.704-2(g)(1) and 1.704-2(i)(5), each such Member
shall be specially allocated items of Company income and gain in the amount of
such excess as quickly as possible, provided that an allocation pursuant to this
Section 7.3(c) shall be made only if and to the extent that such Member would
have a deficit Capital Account in excess of such sum after all other allocations
provided for in Section 7.2 and Section 7.3 have been made as if Section 7.3(b)
hereof and this Section 7.3(c) were not in this Operating Agreement.

               (d) CODE SECTION 754 ADJUSTMENTS. To the extent an adjustment to
the adjusted tax basis of any Company asset purchase to Code Section 734(b) or
Code Section 743(b) is required, pursuant to Treasury Regulations Section
l.704-l(b)(2)(iv)(m), to be taken into account in determining Capital Accounts,
the amount of such adjustment to the Capital Accounts shall be treated as an
item of gain (if the adjustment increases the basis of the asset) or loss (if
the adjustment decreases such basis) and such gain or loss shall be specially
allocated to the Members in a manner consistent with the manner in which their
Capital Accounts are required to be adjusted pursuant to such Section of the
Treasury Regulations.

               (e) CURATIVE ALLOCATIONS. Notwithstanding any other provision of
this Operating Agreement, the Regulatory Allocations shall be taken into account
in allocating items of income, gain, loss and deduction among the Members so
that, to the extent possible, the net amount of such allocations of other items
and the Regulatory Allocations to each Member shall be equal to the net amount
that would have been allocated to each such Member if the Regulatory Allocations
had not occurred. For purposes of applying the foregoing sentence, allocations
pursuant to this Section 7.3(e) shall only be made with respect to allocations
pursuant to Section 7.3(d) hereof to the extent the Managers reasonably
determine that such allocations will otherwise be inconsistent with the economic
agreement among the parties to this Operating Agreement.



                                       16

        7.4    ALLOCATION OF NONRECOURSE ITEMS.

               (a) COMPANY NONRECOURSE DEDUCTIONS. Any Company Nonrecourse
Deductions for any Fiscal Year or Accounting Period shall be allocated to the
Members in accordance with their respective Interests.

               (b) MEMBER NONRECOURSE DEDUCTIONS. Any Member Nonrecourse
Deductions for any Fiscal Year or Accounting Period shall be specially allocated
to the Member who bears the Economic Risk of Losses with respect to the Member
Nonrecourse Debt to which such Member Nonrecourse Deductions are attributable in
accordance with Treasury Regulations Section 1.704-2(i).

               (c) COMPANY MINIMUM GAIN CHARGEBACK. Notwithstanding any other
provision of this Article 7, if there is a net decrease in Company Minimum Gain
during any Fiscal Year, each Member shall be specially allocated items of
Company income and gain for such year (and, if necessary, subsequent years) in
an amount equal to the greater of (i) the portion of such Member's share of the
net decrease in Company Minimum Gain, determined in accordance with Treasury
Regulations Section 1.704-2(g), that is allocable to the disposition of Company
Property subject to such Nonrecourse Liability, determined in accordance with
Treasury Regulations Section 1.704-2(f), or (ii) the negative balance standing
in such Member's Capital Account. Allocations pursuant to the previous sentence
shall be made in proportion to the respective amounts required to be allocated
to each Member pursuant thereto. The items to be so allocated shall be
determined in accordance with Treasury Regulations Section 1.704-2(f)(6). This
Section 7.4(c) is intended to comply with the minimum gain chargeback
requirements set forth in Treasury Regulations Section 1.704-2(f)(6) and shall
be interpreted consistently therewith.

               (d) MEMBER MINIMUM GAIN CHARGEBACK. Notwithstanding any other
provision of this Article 7 (except Section 7.4(c), which shall be applied
first), if there is a net decrease in Member Minimum Gain attributable to a
Member Nonrecourse Debt during any Fiscal Year or Accounting Period, each Member
who has a share of the Member Minimum Gain attributable to such Member
Nonrecourse Debt, determined in accordance with Treasury Regulations Section
1.704-2(i)(5), shall be specially allocated items of Company income and gain for
such year (and if necessary, subsequent years) in an amount equal to the greater
of (i) the portion of such Member's share of the net decrease in Member Minimum
Gain attributable to such Member Nonrecourse Debt, determined in accordance with
Treasury Regulations Section 1.704-2(i)(5), that is allocable to the disposition
of Company Property subject to such Member Nonrecourse Debt, determined in
accordance with Treasury Regulations Section 1.704-2(i)(4) or (ii) the negative
balance standing in such Member's Capital Account. Allocations pursuant to the
previous sentence shall be made in proportion to the respective amounts required
to be allocated to each Member pursuant thereto. The items to be so allocated
shall be determined in accordance with Treasury Regulations Section
1.704-2(i)(4). This Section 7.4(d) is intended to comply with the minimum gain
chargeback requirements set forth in Treasury Regulations Section 1.704-2(i)(4)
and shall be interpreted consistently therewith.

<PAGE>   18

               (a) No distribution shall be declared and paid to a Member to the
extent that at the time of distribution, after giving effect to the
distribution, all liabilities of the Company, other than liabilities to Members
on account of their Interests and liabilities for which the recourse of
creditors is limited to specific property of the Company, exceed the fair market
value of the assets of the Company, except that the fair market value of
property that is subject to a liability for which the recourse of creditors is
limited shall be included in the assets of the Company only to the extent that
the fair market value of the property exceeds that liability.

               (b) A Member who receives a distribution in violation of Section
7.5(a), and who knew at the time of the distribution that the distribution
violated Section 7.5(a), shall be liable to the Company for the amount of the
distribution. A Member who receives a distribution in violation of Section
7.5(a), and who did not know at the time of the distribution that such
distribution violated Section 7.5(a) and shall have made a good faith effort to
return as much as possible of the improper distribution shall not be liable for
the amount of the distribution.

               (c) A Member who receives a distribution from the Company shall
have no liability under this Section 7.5 or other applicable law for the amount
of the distribution after the expiration of three (3) years from the date of the
distribution unless an action to recover the distribution from such Member is
commenced prior to the expiration of the said three (3) year period and an
adjudication of liability against such Member is made in the said action.

        7.6 ACCOUNTING PRINCIPLES. The profits and losses of the Company shall
be determined in accordance with generally accepted accounting principles
applied on a consistent basis.

        7.7 INTEREST ON AND RETURN OF CAPITAL CONTRIBUTIONS. No Member shall be
entitled to interest on its Capital Contribution or to return of its Capital
Contribution, except as otherwise specifically provided for herein.

        7.8 LOANS TO COMPANY. Nothing in this Operating Agreement shall prevent
any Member from making secured or unsecured loans to the Company by agreement
with the Managers on behalf of the Company.

        7.9 RECORDS AND REPORTS. At the expense of the Company, the Managers
shall maintain records and accounts of all operations and expenditures of the
Company and shall keep the following records:

               (a) A current list of the full name and last known business
address of the Managers and each Member;

               (b) A copy of the Certificate of Formation and all amendments
thereto, together with executed copies of any written powers of attorney

                                 TRANSFERABILITY

        8.1 TRANSFER. Except as provided in this Section 8.1, Section 8.2 or
Section 8.4 or Article 13 below or with the prior written consent of Members
holding at least two-thirds of the Interests (which consent shall not be
withheld in the event of a proposed transfer pursuant to a sale of all or
substantially all of the assets of a Member), no Member may shall sell, assign,
give, pledge, hypothecate, encumber or otherwise transfer ("transfer") its
Interest, or any portion thereof, or any other right or interest in all or any
of the assets of the Company.

        8.2 PERMITTED TRANSFERS. Notwithstanding the provisions of Section 8.1,
a Member may, without the consent of the Managers, transfer all or any portion
of its Interest to an Affiliate that is the sole owner of or is wholly owned and
controlled by such Member.

        8.3 CONDITIONS OF TRANSFER. Subject to the provisions of Sections 8.1
and 8.2, no Member shall sell, assign or otherwise transfer all or less than all

writing to become a Member in the Company bound by all the terms and conditions

Members holding at least two-thirds of the Interests which may be withheld or
granted in their sole discretion.

        8.4 RIGHT TO ACQUIRE INTEREST. Notwithstanding the foregoing or anything
else herein to the contrary, upon the occurrence of a Bankruptcy with respect to
a Member, the trustee, receiver or similar representative for the Bankrupt
Member will notify each other Member in writing of such Bankruptcy within 10
days after his or her appointment, or if no such representative is appointed for
the Bankrupt Member, such notice will be given by the Bankrupt Member within
such period of time. Notwithstanding the obligation to deliver any such notice,
the occurrence of any such Bankruptcy shall immediately subject the Bankrupt
Member to the Buy-Sell provisions of Article 13.

the assignment will be entitled to the allocations and distributions
attributable to the interest assigned to such assignee and will be subject to
the transfer, assignment and withdrawal provisions of this Operating Agreement
applicable to Members; however, such assignee will not be entitled to the other
rights of a Member (including, for example and without limitation, the right to

consent of Members holding at least two-thirds of the Interests, which consent
may be granted or withheld in the Members' sole discretion. The assignee will be
subject to the obligations of a Member hereunder, including, without limitation,
this Article 8. Notwithstanding the above, neither the Company nor the Managers
will incur liability for allocations and distributions made in good faith to the
transferring Member until the written instrument of assignment has been received
by the Company and recorded on its books, any documents required by the Company
pursuant to Article 8 have been executed and received by the Company and the
effective date of the transfer has passed.

        8.6 EFFECT OF TRANSFER. The transfer of a Member's Interest or any part
thereof will not be cause for dissolution of the Company.

Section 1.1(a) upon the addition of an Additional Member.

                                   ARTICLE 10

               (b) subject to Section 5.4, by the approval of Members holding at
least two-thirds of the Interests; or

18-802 of the Delaware Act.

        10.2 EFFECT OF FILING OF CERTIFICATE OF CANCELLATION. The Company shall
cease to carry on its business, except insofar as may be necessary for the
winding up of its business, upon the occurrence of a final dissolution event,

dissolving the Company has been entered by a court of competent jurisdiction.

        10.3 DISTRIBUTION OF ASSETS UPON DISSOLUTION. In settling accounts after
dissolution, the liabilities of the Company shall be entitled to payment in the
following order:

               (a) those to creditors, in the order of priority as provided by
law and those to Members who have made loans to the Company pursuant to Section
6.1(c), but except those to Members of the Company on account of their Capital
Contributions; and

               (b) those to Members of the Company, with respect to their
Capital Accounts in accordance with Section 6.3(d).

        10.4 WINDING UP. Except as provided by law, upon dissolution, each
Member shall look solely to the assets of the Company for the return of its
Capital Contribution. If the Company Property remaining after the payment or
discharge of the debts and liabilities of the Company is insufficient to return
the Capital Contribution of each Member, such Member shall have no recourse
against any other Member. The winding up of the affairs of the Company and the
distribution of its assets shall be conducted exclusively by the Managers, who
are hereby authorized to take all actions necessary to accomplish such
distribution, including without limitation, selling any Company assets the
Managers deem necessary or appropriate to sell.

        10.5   FILING OF CERTIFICATE OF CANCELLATION.

               (a) When all debts, liabilities and obligations have been paid
and discharged or adequate provisions have been made therefor and all of the
remaining property and assets have been distributed to the Members, a
Certificate of Cancellation shall be executed in duplicate and verified by the
person signing the certificate, which certificate shall set forth the
information required by the Delaware Act. Duplicate originals of such
Certificate of Cancellation shall be delivered to the Delaware Secretary of
State.

               (b) Upon the acceptance of the Certificate of Cancellation, the
existence of the Company shall cease, except for the purpose of suits, other
proceedings and appropriate action as provided in the Delaware Act. The Managers
shall thereafter be trustee for the Members and creditors of the Company and as
such shall have authority to distribute any Company Property discovered after
dissolution, convey real estate and take such other action as may be necessary
on behalf of and in the name of the Company.

                                   ARTICLE 11

                             MERGER OR CONSOLIDATION

        11.1 MERGER OR CONSOLIDATION. The Company may, upon a vote of the
Members holding at least two-thirds of the Interests, merge or consolidate
pursuant to an agreement of merger or consolidation with or into one or more
entities formed or organized under the laws of the State of Delaware or any
other state of the United States or any foreign country or other foreign
jurisdiction, with such entity as the agreement shall provide being the
surviving or resulting entity.

        11.2 EXCHANGE RELATING TO MERGER OR CONSOLIDATION. Rights or securities
of, or Interests in, the Company or other entity that is a constituent party to
the merger or consolidation may be exchanged for or converted into cash,
property, rights or securities of, or Interests in, the surviving or resulting
entity or, in addition to or in lieu thereof, may be exchanged for or converted
into cash, property, rights or securities of, or Interests in, an entity which
is not the surviving or resulting entity in the merger or consolidation.

        11.3 FILING AND EFFECT OF CERTIFICATE OF MERGER OR CONSOLIDATION. If the
Company enters into an agreement of merger or consolidation, the surviving
entity shall file a Certificate of Merger or Consolidation in the Office of the
Secretary of State of the State of Delaware containing the information required
by Section 18-209(c) of the Delaware Act. Unless a future date is provided for
in such Certificate of Merger or Consolidation, the effective date shall be the
date of filing with the Secretary of State of the State of Delaware. Such
Certificate of Merger or Consolidation shall act as a Certificate of
Cancellation for the Company if it is not the surviving or resulting entity in
the merger or consolidation.

        11.4 AMENDMENT OF OLD OR ADOPTION OF NEW OPERATING AGREEMENT. An
agreement of merger or consolidation approved in accordance with Section
5.4(a)(vii) may effect any amendment to the Company's Operating Agreement or
effect the adoption of a new Operating Agreement for the Company or the
surviving entity, as the case may be. Any amendment of this



                                       22
<PAGE>   23

Operating Agreement or adoption of a new Operating Agreement shall be effective

powers of the Company and each of the other entities that have merged or
consolidated, and all property, real, personal and mixed, and all debts due or
incurred to or by any of the constituent parties, as well as all other things
and causes of action belonging to each of such parties to the merger or
consolidation, shall be vested in the surviving or resulting entity, and shall
thereafter be the property or obligation of the surviving or resulting entity,
and the title to any real property vested by deed or otherwise shall not revert
or be in any way impaired.

        11.6 NET INCOME BASE OBLIGATION ACCELERATION. In addition to the
foregoing provisions of this Article 11, in the event of any merger or
consolidation pursuant to which the Members hold less than a controlling
ownership and voting interest of any successor or surviving entity, the
Company's obligation to make all remaining Net Income Base distributions (up to
the balance of the outstanding Aggregate net Income Base Obligation) shall be
accelerated and shall be payable to Stadtlander upon the consummation of such
merger or consolidation, discounted at the rate of the Wall Street Journal prime
rate as of the date of such event plus 1.5% per year.

                                   ARTICLE 12

           NONCOMPETITION, CONFIDENTIALITY AND PROPRIETARY INFORMATION

        12.1 NONCOMPETITION; CONFIDENTIALITY. As an inducement for each of the
parties to enter into this Operating Agreement, to purchase and sell membership
interests in the Company, and in order to preserve the goodwill to be developed
by and acquired by Company in its business the parties agree as follows:

               (a) MEMBERS' COVENANT NOT TO COMPETE. During the term of this
Operating Agreement and for a period of three (3) years from the termination of
this Operating Agreement or with respect to a Member that has transferred all of
its Interest, three (3) years from the date of the transfer of all of that
Member's Interest, no Member nor any Affiliate thereof will directly or
indirectly engage in any Competitive Activities. The term "Competitive
Activities" as used herein shall mean:

                      (i) directly or indirectly engaging in, continuing in or
carrying on any business involved in providing specialty pharmaceutical services
to patients diagnosed with a serious mental illness or conducting clinical
research or site management and information services relating to healthcare
informatics, clinical practices, pharmaceutical usage and patient outcomes
relating to patients with a serious mental illness, or any business that is
substantially similar thereto, including owning or controlling any financial
interest in any corporation, partnership, firm or other form of business
organization which competes with or is engaged in or carries on any aspect of
such business or any business substantially similar thereto;

                      (ii) serving as a shareholder, officer, director, member,
manager, trustee or partner of, or consulting with, advising or assisting in any
way, whether or not for



                                       23
<PAGE>   24

consideration, any corporation, partnership, firm, proprietorship or other
business organization which is now, becomes or may become a competitor of
Company in any aspect with respect to the Company's business, including, but not
limited to, advertising or otherwise endorsing the services of any such
competitor; soliciting customers, providers or otherwise serving as an
intermediary for any such competitor; loaning money or rendering any other form
of financial assistance to or engaging in any form of business transaction on
other than an arm's length basis with any such competitor;

                      (iii) engaging in any practice the purpose of which is to
evade the provisions of this covenant not to compete or to commit any act which
is detrimental to the successful continuation of Company's business by Company
or which adversely affects its business.

The term "Competitive Activities" shall not include (A) the ownership of
securities of corporations which are listed on a national securities exchange or
traded in the national over-the-counter market in an amount which shall not
exceed 5% of the outstanding shares of any such corporation, (B) acquiring a
business that is competitive with the Company pursuant to the acquisition of an
entity or group of affiliated entities whose principal business is not in
competition with the Company, provided that in no event shall revenues of such
Member derived from the business that is directly competitive with the Company's
business exceed twenty-five percent (25%) of the Company's revenues, or (C) any
activities of Counsel Corporation or its Affiliates that would otherwise be
deemed Competitive Activities above other than, so long as Counsel Corporation
holds a controlling interest in Stadtlander, initiating or creating any business
or entity which competes with the Company or acquiring any business or entity
whose principal business is in competition with the Company, or whose principal
business is not in competition with the Company but the revenues derived from
the business directly competitive with the Company exceeds fifty percent (50%)
of the Company's revenues.

The parties agree that the geographic scope of this covenant not to compete
shall extend throughout the United States. The parties agree that Company may
sell, assign or otherwise transfer this covenant not to compete, in whole or in
part, to any person, corporation, firm or entity that purchases all or part of
the capital stock or all or substantially all of the assets of the Company. In
the event a court of competent jurisdiction determines that the provisions of
this covenant not to compete are excessively broad as to duration, geographical
scope or activity, it is expressly agreed that this covenant not to compete
shall be construed so that the remaining provisions shall not be affected, but
shall remain in full force and effect, and any such over broad provisions shall
be deemed, without further action on the part of any person, to be modified,
amended and/or limited, but only to the extent necessary to render the same
valid and enforceable in such jurisdiction.

               (b) COMPANY'S COVENANT NOT TO COMPETE. During the term of this
Operating Agreement and for a period of three (3) years from the termination of
this Operating Agreement or with respect to a Member that has transferred all of
its Interest, three (3) years from the date of the transfer of all of that
Member's Interest, neither the Company nor any subsidiary of the Company will
directly or indirectly engage in any activity which is competitive with the
principal business of any Member or its Affiliates. Prohibited activity
hereunder includes:



                                       24
<PAGE>   25

                      (i) owning or controlling any financial interest in any
corporation, partnership, firm or other form of business organization which
competes with or is engaged in or carries on any aspect of a Member's business
or any business substantially similar thereto;

                      (ii) serving as a shareholder, officer, director, member,
manager, trustee or partner of, or consulting with, advising or assisting in any
way, whether or not for consideration, any corporation, partnership, firm,
proprietorship or other business organization which is now, becomes or may
become a competitor of a Member in any aspect with respect to the Member's
business, including, but not limited to, advertising or otherwise endorsing the
services of any such competitor; soliciting customers, providers or otherwise
serving as an intermediary for any such competitor; loaning money or rendering
any other form of financial assistance to or engaging in any form of business
transaction on other than an arm's length basis with any such competitor; and

                      (iii) engaging in any practice the purpose of which is to
evade the provisions of this covenant not to compete or to commit any act which
is detrimental to the successful continuation of a Member's business by such
Member or which adversely affects its business; provided, however, that the
prohibited activities hereunder shall not include the ownership of securities of
corporations which are listed on a national securities exchange or traded in the
national over-the-counter market in an amount which shall not exceed 5% of the
outstanding shares of any such corporation.

The parties agree that the geographic scope of this covenant not to compete
shall extend throughout the United States. The parties agree that any Member may
sell, assign or otherwise transfer this covenant not to compete, in whole or in
part, to any person, corporation, firm or entity that purchases all or part of
the capital stock or all or substantially all of the assets of such Member. In
the event a court of competent jurisdiction determines that the provisions of
this covenant not to compete are excessively broad as to duration, geographical
scope or activity, it is expressly agreed that this covenant not to compete
shall be construed so that the remaining provisions shall not be affected, but
shall remain in full force and effect, and any such over broad provisions shall
be deemed, without further action on the part of any person, to be modified,
amended and/or limited, but only to the extent necessary to render the same
valid and enforceable in such jurisdiction.

               (c) COVENANT OF CONFIDENTIALITY. During the term of this
Operating Agreement and for a period of three (3) years from the termination of
this Operating Agreement, no Member shall, except as explicitly permitted under
any other agreement between Company and any Member, (i) use for any purpose,
(ii) disclose to any person, or (iii) keep or make copies of documents, tapes,
discs or programs containing, any confidential information concerning Company's
business. For purposes hereof, "confidential information" shall mean and
include, without limitation, all intellectual property, trade secrets, reports,
financial information, business plans, customer and/or provider lists and
customer and/or provider information, and all other information concerning
Company's business and marketing methods used in connection with its business,
not previously disclosed to the public directly by Company. The provisions of
this Section 12.1(c) shall not supercede, modify or affect in any way any
similar confidentiality provisions in any other agreement between Company and
any Member(s), including the Transition and Services Agreement, and so long as
any such agreement is in effect, the



                                       25
<PAGE>   26

confidentiality provisions therein shall govern in the event of a conflict with
the provisions of this Section 12.1(c).

               (d) COMPANY PROPRIETARY INFORMATION. Notwithstanding the nature
of any assets or information contributed to Company by any Member, all patient
and customer information developed by Company shall be proprietary to Company
and no Member will have any ownership interest in such proprietary information
(except to the extent such Member may have an interest in such assets upon the
liquidation of Company by virtue of the Member's Interest).

               (e) EQUITABLE RELIEF FOR VIOLATIONS. The parties agree that the
provisions and restrictions contained in this Section 12.1 are necessary to
protect the legitimate continuing interests of Company and each Member, and that
any violation or breach of these provisions will result in irreparable injury to
Company or such Member for which a remedy at law would be inadequate and that,
in addition to any relief at law which may be available to such party for such
violation or breach and regardless of any other provision contained in this
Operating Agreement, such party shall be entitled to injunctive and other
equitable relief as a court may grant after considering the intent of this
Section 12.1.

                                   ARTICLE 13

                                    BUY-SELL

        13.1 BUY-SELL. Upon the earlier of any Bankruptcy of a Member or January
1, 2001 (the "Buy-Sell Right Inception"), Members shall have the rights of
purchase and sale provided by this Section 13.1, to be exercised by delivering a
notice (an "Election Notice"). A Member giving an Election Notice as provided
herein is referred to as an "Electing Member," a Member receiving an Election
Notice is referred to as a "Notice Member."

               (a) INVOCATION OF BUY-SELL PROCEDURE. At any time after the
Buy-Sell Right Inception, this buy-sell procedure may be invoked by the giving
of an Election Notice by any Member. Such Election Notice, to be valid, shall
include the Stated Amount of the Members' interests and shall be given to the
Notice Member. The date of such notice shall be referred to as the "Election
Day."

               (b) EFFECT OF ELECTION NOTICE; BUY-SELL PRICE. An Election Notice
shall constitute an irrevocable offer by the Electing Member either to (1)
purchase all, and not less than all, of the Interest of the Notice Member, or
(2) sell all, but not less than all, of its Interest to the Notice Member. The
price at which the Interest of any Member is purchased and sold under this
Section 13.1 (the "Buy-Sell Price" of such Interest) shall be a price determined
by the Electing Member, which shall not be less than the Net Stated Equity
thereof, determined as of the Election Day plus full repayment of any loans to
the Company (plus accrued interest) outstanding and payable to the Member. The
cost of determining Net Stated Equity shall be borne by the Company and shall be
treated as an expense for purposes of such determination.

               (c) NOTICE MEMBER'S ELECTION TO PURCHASE OR SELL. For a period
(the "Election Period") ending at 11:59 P.M. (local time at the Company's
principal place of business) on the sixtieth day following the Election Day, the
Notice Member shall have the right to elect to (i)



                                       26
<PAGE>   27

purchase all, and not less than all, of the Interest of the Electing Member, by
giving notice thereof (the "Purchase Notice") to the Electing Member which
Purchase Notice shall not be valid unless it states such Member (the "Purchasing
Member") is electing to purchase all of the Electing Member's Interest (as the
"Selling Member"); or (ii) obtain a commitment from a nationally recognized
investment banker to act as an underwriter in a public offering of the Company's
securities for an aggregate value that is at least as beneficial to the Member
who delivered the Election Notice as the price of the Interest. A Purchasing
Member, upon sending a Purchase Notice, shall be obligated to purchase all of
the Electing Member's Interest. If the Notice Member elects to obtain an
investment banker commitment to offer the Company's securities in a public
offering, the public offering shall be consummated within 150 days of the date
of such election. If (i) no Purchase Notice is sent, (ii) no investment banker
commitment is obtained, or (iii) if an investment banker commitment is obtained
but the public offering is not consummated within the 150-day period, the
Electing Member shall become the Purchasing Member and shall be obligated to
purchase all of the Interest of the Notice Member in accordance with the
Election Notice, who shall become the Selling Member and shall be obligated to
sell all of its interest to the Purchasing Member.

               (d) TERMS OF PURCHASE; CLOSING. The closing of the purchase and
sale of the Selling Member's Interest shall occur on a date and time mutually
agreeable to the Purchasing Member and the Selling Member, which shall not be
later than 10:00 A.M. (local time at the place of the closing) on the first
business day occurring on or after the sixtieth day following the Election Day
and at such place as is mutually agreeable to the Purchasing Member and Selling
Member, or upon the failure to agree, at the Company's principal place of
business. At the closing the Purchasing Member shall pay to the Selling Member,
by cash or other immediately available funds, the Buy-Sell Price of such Selling
Member's Interest, and the Selling Member shall deliver to the Purchasing Member
good title, free and clear of any liens, claims, encumbrances, security
interests or options (other than those granted by this Agreement) to the Selling
Member's Interest thus purchased.

        At the closing the Members shall execute such documents and instruments
of conveyance as may be necessary or appropriate to confirm the transactions
contemplated hereby, including, without limitation, the transfer of the Company
Interest of the Selling Member to the Purchasing Member and the assumption by
the Purchasing Member of the Selling Member's obligations with respect to the
Selling Member's Interest transferred to the Purchasing Member. The reasonable
costs of such Transfer and closing, including, without limitation, attorneys'
fees and filing fees, shall be divided equally between the Selling Member and
the Purchasing Member.

        13.2 NET EQUITY. The "Net Stated Equity" of a Member's Interest in the
Company, as of any day, shall be the amount that would be distributed to such
Member in dissolution of the Company pursuant to Article 10 hereof if (1) all of
the Company's assets were sold for the Stated Amount, (2) the Company paid its
accrued, but unpaid, liabilities and established reserves for the payment of
reasonably anticipated contingent or unknown liabilities, and (3) the Company
distributed the remaining proceeds to the Members in liquidation, all as of such
day.

        The Net Stated Equity of a Member's Interest in the Company shall be

                              ADDITIONAL COVENANTS

        14.1 ARBITRATION. In the event of a dispute under this Operating
Agreement, including any Impasse (as defined below) or any dispute raised by a
Member claiming that the actions or omissions of the Managers are detrimental to
the Member as a holder of a minority interest, the Members agree that they will
submit the resolution of any such dispute or Impasse to binding arbitration in
accordance with the then-current commercial arbitration rules of the American
Arbitration Association. The arbitration shall be conducted in San Diego County,
California. The decision of the arbitrator(s) shall be in accordance with the
best interests of the Company and in no event shall any decision by an
arbitrator(s) conflict with the provisions of this Agreement. The decision of
the arbitrator(s) shall be binding on the parties, and judgment in accordance
with that decision may be entered in any court having jurisdiction thereof. The
arbitrator(s) shall be empowered to award specific performance, injunctive
relief and damages (but not exemplary damage). An "Impasse" shall be deemed to
occur if at any time: (i) a disagreement between the Members or among the
Managers occurs with respect to any significant business matter or the
consideration of a proposal by either Member to sell all or substantially all of
the assets of the Company or to enter into a merger or consolidation; or (ii)
the Managers otherwise become deadlocked.

Operating Agreement shall not prevent a subsequent act, which would have
originally constituted a violation, from having the effect of an original
violation.

        15.9 RIGHTS AND REMEDIES CUMULATIVE. The rights and remedies provided by
this Operating Agreement are cumulative, and the use of any one right or remedy
by any party shall not preclude or waive the right to use any or all other
