Notwithstanding the foregoing, Employee shall not be deemed to be rendering

(a) Employer gives written notice to Employee of Employer's belief that Employee
is rendering services to an extent prohibited by the provisions of the preceding
sentence (such notice shall specify the reasons for such belief), and (b) 
Employee fails, within 30 days after the effective date of such notice

        -----------------------------------------------------------------

     The parties hereby expressly agree that Employee's employment by Employer 
may terminate or be terminated by either party at any time prior to the
Scheduled Termination date as provided below; provided however, that any such
termination of Employee's employment by Employer shall be in accordance with the

Partnership Agreement was first executed. Except as otherwise expressly set 
forth herein, Employee shall not be entitled to any severance pay, relocation

from the date

as of the date of termination, (ii) any compensation owed to Employee pursuant 
to the Profit Sharing Plan pursuant to Section 3(b) hereof as provided therein 
and (iii) any reimbursement amounts owed to Employee and any other amounts owed 
to Employee under any benefit plan (including amounts under any disability plan)
in respect of service through the date of termination.  As used herein, the term
permanent incapacity means the inability of Employee, by reason of injury, 
illness of other similar cause to perform a major part of his duties and 
responsibilities in connection with the conduct of the business and affairs of 
Employer and its Affiliates.

        (b) Voluntary Termination and Termination For Cause.  In the event
            -----------------------------------------------
of (i) a termination of Employee's employment by reason of a Voluntary 
Termination or (ii) in the event of Employee's termination by Employer for 
Cause, then (A) all obligations of Employer under any Section of this Agreement 
shall terminate as of the date of such termination, (B) all obligations of 
Employer and its Affiliates under the Profit Sharing Plan shall terminate as 
provided therein, and (C) Employee's obligations under Section 6(a) and Section 
6(c) hereof shall continue unaffected by the termination of Employee's 
employment in accordance with the terms thereof and, as a material consideration
for its agreements hereunder and other arrangements in connection with the 
Consolidation, Employer shall have the right to enforce such obligations to the 
full extent set forth therein.  Employee agrees to give Employer at least six 
months prior written notice of any Voluntary Termination hereunder.

     As used herein, the term "For Cause" shall mean any of the following:

        (i)   Employee has engaged in actions which both constitute a
              Termination Offense, and are of a nature which if publicly known
              would materially and adversely affect Employer's business; and the
              term "Termination Offense" shall mean any felony criminal offense
              which involves a violation of federal or state securities laws or
              regulations, embezzlement, fraud, wrongful taking or
              misappropriation of property, theft, or any other crime involving
              dishonesty;

        (ii)  Employee has persistently and willfully neglected his duties as
              provided herein after Employer has given Employee written notice
              specifying such conduct by Employee and giving Employee a 
              reasonable period of time (not less than 45 days), to conform his
              conduct to such duties; or

        (iii) Employee has engaged in Prohibited Competition Activity.

     Any determination as to whether Employee has been terminated For Cause for
purposes of this Agreement shall be made without reference to the determination

                                       8
<PAGE>
 
required to be made under the Partnership Agreement and the related definition 
of "For Cause" in that Agreement.

     (c)  Involuntary Termination and Default by Employer.  In the event of the
          -----------------------------------------------
Involuntary Termination of Employee's employment by Employer, then (i) Employer 
shall continue to pay Employee his base salary as was in effect as of the 
Employment Termination Date subject to the CPI adjustment for the longer of one 
year from the Employment Termination Date or through the then Scheduled 
Termination Date and during such period shall continue in effect Employee's 
benefits in accordance with Section 4(a), (ii) Employee shall be entitled to 
participate in the Profit Sharing Plan to the extent and only to the extent 
provided therein and (iii) all obligations of Employee under this Agreement 
other than Section 6(a) hereof shall terminate; provided, however, that in the 
event that Employee engages in any of the activities described in Section 6(c) 
hereof following any such termination, then Employer's obligations under clause 
(i) above shall terminate.  After any  material default by Employer in the 
performance of any of its obligations hereunder, Employee shall have the right
to terminate his employment hereunder for a period of three months thereafter,
and such termination shall be deemed an Involuntary Termination by Employer.
Notwithstanding the foregoing, Employer shall not be deemed to have committed a
material default hereunder unless and until (x) Employee gives written notice to
Employer of Employee's belief that Employer has committed such a default, and
(y) Employer fails, within 30 days after the effective date of such notice
(determined as provided in Section 8 hereof), to cure such default. Payment of
the amount specified in this Section 5(c) is agreed by the parties hereto to be
in full satisfaction and compromise of any claims arising out of any termination
of Employee's employment pursuant to this Section 5(c).

covenants that during the term of his employment with Employer he will not 
engage in any Prohibited Competition Activity. Without limitation of any other
provision of this Agreement, the restrictions set forth in this Section 6(a)
shall in no event be applicable to or restrict Employee following termination of

agreements, and any other incident of any business developed by Employer or
earned or carried on by Employer and all trade names, service marks and logos

shall be payable directly to Employer or such Affiliate.  Employee acknowledges

and similar and other confidential information owned or used in the course of
business by Employer or its Affiliates. Employee agrees always to keep secret

confidential or proprietary nature with respect to any trade secrets,

operations or techniques of Employer or any of its Affiliates. Upon termination
of Employee's services to Employer for any reason, all data, memoranda, client
lists, notes, programs and other papers, items and tangible media, and
reproductions thereof relating to the foregoing matters in Employee's possession
or control, shall be returned to Employer and remain in its possession (except
where the return of such items shall be unreasonable or impractical in relation
to the importance of confidentiality of such items).

        (c)  In further reflection of Employer's important interests in its 
proprietary information and trade and employee relationships as contemplated by 
Section 6(b), Employee agrees that, following the Employment Termination Date,

than Employer or any Affiliate of Employer:

             (A) provide investment advisory, investment management or any other
        services to any person or entity that is a client of Employer (for this
        purpose, a "client of Employer" is any person or entity for whom 
        Employer is performing Investment Management Services at the Employment
        Termination Date or for whom Employer performed Investment Management
        Services at any time during the six months immediately preceding the
        Employment Termination Date and any person or entity with whom Employer
        was actively attempting to develop an investment advisory relationship
        during such period); provided,

                                      10

             providing investment advisory or investment management or other 
             services to any person or entity that is not a client of Employer,
             and (2) shall not prohibit Employee from working as part of an
             enterprise having clients of Employer as its clients as long as
             Employee can demonstrate by clear and convincing evidence that he
             has no direct or indirect involvement with the management of such
             clients' accounts or the provision of advice or other services with
             respect thereto and that he has refrained from contacting such
             clients directly or indirectly;

                 (B) divert or take away any Employer Managed Funds or solicit
             any person or entity for the purpose of diverting or taking away
             any such Employer Managed Funds; or

                 (C) solicit or induce any professional employee or former 
             professional employee of Employer to terminate his relationship
             therewith, hire any such professional employee, or work in any
             enterprise involving investment advisory services with any
             professional employee or former professional employee of Employer

passive investments in a competitive enterprise the shares of which are publicly
traded provided his holding therein, together with any holdings of his 
Affiliates, do not exceed 1% of the outstanding shares or comparable interests 
in such entity.

             (d) Employer shall not have the right to enforce the provisions of
Section 6(c) following any termination of employment prior to the Scheduled
Termination Date by reason of death or permanent incapacity as provided in 
Section 5(a) or Involuntary Termination as provided in Section 5(c), its sole

provision had been limited or modified (consistent with its general intent) to 
the extent necessary to make it valid, legal and enforceable, or if it shall not

provision or part of a provision, this Agreement shall be construed as if such 
invalid, illegal or unenforceable provision or part of a provision had never 
been contained in this Agreement.
