parties, be retained by the Company.

     Section 3. Restrictions on Transfers.

     3.A.  Restrictions.  Restricted Securities are transferable pursuant to (i)
public offerings registered under the Securities Act, (ii) Rule 144 or Rule 144A
of the Securities and Exchange Commission (or any similar rule then in force) if
such rule is  available,  and  (iii)  subject  to the  conditions  specified  in
paragraph  3B, any other  legally  available  means of transfer  pursuant to the
Securities Act.

     3.B.  Procedure  for  Transfer.  In  connection  with the  transfer  of any
Restricted  Securities (other than a transfer referred to in clauses (i) or (ii)
of paragraph 3A above),  the holder  thereof will deliver  written notice to the
Company  describing  in  reasonable  detail the  transfer or proposed  transfer,
together  with an opinion  (reasonably  satisfactory  to the Company) of counsel
which (to the Company's reasonable  satisfaction) is knowledgeable in securities
law matters to the effect that such  transfer of  Restricted  Securities  may be
effected without registration of such Restricted Securities under the Securities
Act. In addition,  if the holder of such Restricted  Securities  delivers to the
Company an opinion of such counsel to the effect that no subsequent  transfer of
such Restricted  Securities will require  registration under the Securities Act,
the  Company  will  promptly  upon  such   contemplated   transfer  deliver  new
certificates for such Restricted Securities which do not bear the Securities Act
Legend  set forth in  paragraph  5A below.  If the  Company is not  required  to
deliver new certificates for such Restricted Securities not bearing such legend,
the holder thereof will not transfer the same until the  prospective  transferee
has  confirmed  to the  Company  in  writing  its  agreement  to be bound by the
conditions contained in this paragraph and paragraph 5A.


     3.C. Transferees. Upon request of any Purchaser, the Company shall promptly
supply to such Purchaser or its prospective transferees all information required
to be  delivered  in  connection  with a transfer  pursuant  to Rule 144A of the
Securities and Exchange commission.

valid and binding  obligation of the Company  enforceable in accordance with its
terms,  subject to the  availability  of  equitable  remedies and to the laws of

Incorporation or the Bylaws, or any law, statute, rule, regulation,  instrument,

representations  set  forth in  Section 5 hereof,  the  offers  and sales of the
Junior  Preferred  Stock  pursuant  to the terms  hereof are not  required to be
registered under the Securities Act or any state securities laws.


     Section 5.  Purchasers' Representations and Warranties.

     5.A. Purchasers' Investment  Representations.  Each Purchaser individually,
and not jointly or severally,  hereby  represents that he or it is acquiring the

present intention of holding such securities for investment purposes and that it
has no  intention  of  selling  such  securities  in a  public  distribution  in

from transferring such securities in compliance with the provisions of Section 3
hereof.  Each  certificate  for  Restricted  Securities  will  be  conspicuously
imprinted with a legend substantially in the following form (the "Securities Act

     ORIGINAL  PURCHASER HEREOF, AND THE COMPANY RESERVES THE RIGHT TO REFUSE TO
     TRANSFER SUCH  SECURITIES  UNTIL SUCH  CONDITIONS  HAVE BEEN FULFILLED WITH
     RESPECT TO SUCH TRANSFER.  UPON WRITTEN REQUEST,  A COPY OF SUCH CONDITIONS
     WILL BE FURNISHED BY THE COMPANY TO THE HOLDER HEREOF WITHOUT CHARGE."

Whenever any shares of Junior Preferred Stock cease to be Restricted  Securities
and are not otherwise restricted securities, the holder thereof will be entitled
to receive from the Company,  without expense,  upon surrender to the Company of
the  certificate  representing  such  shares of Junior  Preferred  Stock,  a new
certificate representing such shares of Junior Preferred Stock of like tenor but
not bearing a legend of the character set forth above.

present time, is able to afford a complete loss of such investment; and

     (iii) the Purchaser  has all  requisite  power and authority to enter into,
deliver  and  consummate  the   transactions   contemplated  by  this  Agreement
(including  the purchase of the  securities  to be  purchased  by the  Purchaser
hereunder) and this Agreement has been duly  authorized,  executed and delivered
by the Purchaser and constitutes a valid and binding obligation of the Purchaser

jurisdiction.

     7.F. Counterparts.  This Agreement may be executed simultaneously in two or
