         WHEREAS,  Assignor wishes to assign to Assignee, and Assignee wishes to
accept  assignment from Assignor,  (i) all of Assignor's  rights and obligations
under the Stock  Purchase  Agreement to purchase  from Seller  23,300  shares of

with respect to the Assigned Shares;

         WHEREAS,  pursuant to an Investment  Management  Agreement between RCBA
and  Assignee,   dated  July  1,  1993,  RCBA  is  the  investment  manager  and
attorney-in-fact for the Assignee with respect to certain investments;

         NOW, THEREFORE,  in consideration of the premises and of the respective
representations,  warranties,  covenants,  agreements and  conditions  contained
herein and other good and valuable  consideration the receipt and sufficiency of
which is hereby acknowledged, each of the parties agrees as follows:

         1.       Assignment and Assumption.

         (a) Upon the terms and subject to the conditions  appearing herein, the
Assignor  hereby  transfers,  assigns  and  delegates  to  the  Assignee  all of
Assignor's rights, title, interest, remedies, duties and obligations relating to
the  purchase  of  the  Assigned  Shares  under  the  Stock  Purchase  Agreement
(collectively, the "Assigned Rights").

         (b) Upon the terms and subject to the conditions  appearing  herein, on
the basis of the  representations,  warranties  and  covenants  of Seller in the
Stock Purchase Agreement,  Assignee hereby accepts the foregoing  assignment and
delegation and, in addition,  expressly assumes and agrees to keep,  perform and
fulfill all of the terms, covenants,  conditions, duties and obligations insofar
as they relate to the Assignee's purchase of the Assigned Shares of the Series B
Preferred  Stock which are required to be kept,  performed  and fulfilled by the
Assignor  pursuant to the Stock  Purchase  Agreement  from and after the date of
this Assignment. Assignor represents and







warrants that it has delivered to Assignee a true and complete copy of the Stock
Purchase Agreement.

         (c)      Assignor, Assignee and Seller hereby agree as follows:

                  (1) All  obligations  of Assignor and Assignee under the Stock
Purchase  Agreement  shall be several,  and Assignee  and Assignor  shall not be
jointly obligated in any respect.

                  (2) All  covenants,  duties,  obligations  and  liabilities of
Assignee  arising  under  the  Stock  Purchase  Agreement  as a  result  of this
Agreement shall be limited to the covenants, duties, obligations and liabilities
that relate to the  Assigned  Shares.  Without  limiting the  generality  of the
immediately  preceding  sentence,  neither  Assignee nor Assignor shall have any
responsibility  for any breach or  default,  or failure in  performance,  of the
other under the Stock Purchase Agreement.

                  (3)  Except as  hereinafter  provided,  wherever  in the Stock
Purchase  Agreement  there is any  reference to  "Purchaser",  as defined in the
Stock  Purchase  Agreement,  that  reference  shall  mean  and  refer to each of
"Purchaser" and "The Common Fund for NonProfit  Organizations." Without limiting
the  generality of the  foregoing,  (i) all  obligations of Seller to Purchaser,
including,   without  limitation,   those  arising  under  the  representations,
warranties  and  covenants  of Seller in, or as  provided  for under,  the Stock
Purchase  Agreement,  shall  be to each  of  Assignor  and  Assignee,  (ii)  all
approvals,  agreements,  consents  and  waivers  of  Purchaser  under  the Stock
Purchase  Agreement  must be given by each of Assignor and  Assignee,  (iii) all
disclosures  that  Seller  is  required  to make to  Purchaser  under  the Stock
Purchase  Agreement  or  applicable  law and all  information  that  Seller must
provide to Purchaser  must be made and provided to Assignor  and  Assignee,  and
(iv) the Stock  Purchase  Agreement  may not be amended or modified  without the
written consent of each of Assignor and Assignee.

                  (4) Assignee shall not make any  representations or warranties
of Assignor under Article VI of the Stock Purchase  Agreement.  RCBA  represents
and warrants to Seller that it has all requisite power and authority to execute,
deliver, and perform this Agreement on behalf of Assignee.

                  (5)  Seller  shall  take  reasonable   measures  to  establish
procedures to deal with,  and minimize the effects of,  conflicts of interest of
directors  and officers of Seller and shall from time to time  provide  Assignee
with such information  with respect to such procedures and their  application to
specific circumstances as Assignee may reasonably request.

                  (6) All notices to Assignee under the Stock Purchase Agreement
shall be given in the manner provided in Section 14.1 thereof and to Assignee as

Assignment  Agreement  shall be  binding  upon and inure to the  benefit  of the

representations,  covenants or other agreements  except as stated or referred to
herein.

         6.  Assignability.  This  Assignment  Agreement is not  transferable or
assignable by any party hereto.

use of separate  signature pages or in any number of  counterparts,  and each of
such counterparts  shall, for all purposes,  constitute one agreement binding on
