                                PROMISSORY NOTE

                                   EXHIBIT B

                                  SECTION 5.2

     5.2 Incurrence of Indebtedness; Right of First Refusal.

     (a) If, at any time when the Purchaser owns the Threshold Percentage and at
least 25% of the Preferred Stock outstanding  immediately following the Closing,
the Company desires to incur any indebtedness (other than Senior  Indebtedness),
the Company  shall  deliver a written  notice to the  Purchaser of the Company's
good  faith  desire  to  incur  such  indebtedness,  specifying  the  amount  of
indebtedness  the Company  desires to incur and a detailed  explanation  for the
reason it desires to incur such  indebtedness  (the "Offer  Notice").  The Offer
Notice shall set forth the  principal  amount of the desired  indebtedness,  the
term, the facilities for payment,  schedule of payments,  interest rate, and any
other material terms and conditions of the desired indebtedness.

     (b) As promptly as practicable  but in no event later than 15 calendar days
after receipt of an Offer Notice (the "Offer Period"),  the Purchaser shall have
the right, but not the obligation,  to elect to (i) provide the Company with all
the financing so desired, (ii) assign its obligation to provide the Company with
all the financing so desired to one or more of the Company's  direct  Affiliates
or (iii)  provide the Company with less than all of the financing so desired and
assign its  obligation to provide the Company with any remaining  portion of the
financing  so  desired  and not  provided  by the  Company to one or more of the
Company's  direct  Affiliates,  and whether in the case of clause  (i),  (ii) or
(iii) above,  in accordance  with such Offer Notice.  If the Purchaser  makes an
election pursuant to this clause (b), the Purchaser shall give written notice to
the Company,  prior to the  expiration of the Offer Period,  of the  Purchaser's
election and indicate whether the Purchaser has made such election in accordance
with clause (i), (ii) or (iii) of this clause (b) (a "Funding  Notice").  In the
event such  election  is made in  accordance  with  clause (ii) or (iii) of this
clause  (b),  the  Funding  Notice  shall  state the name or names of the direct
Affiliates  to whom the  Purchaser has assigned its  obligation  hereunder  (the
"Specified Affiliates").

     (c) Any financing to be provided by the Purchaser  and/or any of its direct
Affiliate(s)  pursuant  to this  Section  5.2 shall close  within  fifteen  (15)
calendar days after the date of the applicable  Funding Notice.  The Company and
the Purchaser and/or the Specified Affiliate(s) shall enter into an agreement to
effect  such  transaction  on the  terms and  conditions  set forth in the Offer
Notice and with such  representations,  warranties,  covenants,  conditions  and
indemnities as are customary under the circumstances and otherwise  commercially
reasonable.

     (d) In the event the Purchaser  declines (by written  notice  declining the
offer  pursuant to the Offer  Notice) or shall fail to provide a Funding  Notice
prior to the expiration of the Offer Period (the "Date of Rejection"),  then the
Company  shall have the right to engage in a  transaction  pursuant to the terms
set forth in the  Offer  Notice  at any time  within  45 days  after the Date of
Rejection  (the "Sale  Period") upon terms and  conditions no more  favorable to
such party than those specified in the Offer Notice.

                                       7


     (e) For the  purposes of this Section 5.2,  "terms and  conditions  no more
favorable"  shall mean that the  price,  facilities  for  payment,  schedule  of
payments,  interest  rates,  indemnification  provisions  and any other material
terms and  conditions  of the  agreement  pursuant  to which such  financing  is
obtained  by the Company  shall not,  in the  aggregate,  be  economically  more
favorable to such Person than the terms and conditions offered to the Purchaser.

     (f) If such  financing  is not  obtained  by the  Company  within  the Sale
Period, any proposed incurrence of indebtedness (other than Senior Indebtedness)
shall again be subject to the notice  requirements  and rights of first  refusal
set forth in this Section  5.2.

     (g) For purposes of this Section 5.2 only,  the term "the Company" shall be
deemed to include the Company and any of its subsidiaries.

                                       8


                                   EXHIBIT C

                                  SECTION 5.6

        5.6 Confidentiality. The Purchaser covenants and agrees to keep
confidential any and all material non-public information which it has heretofore
obtained or shall hereafter obtain, directly or indirectly, from the Company
pursuant to this Agreement or otherwise, and agrees not to use the same except
for the purpose of this Agreement or to disclose the same to any party except as
provided below, without the Company's prior written consent; provided that the
terms of this Section 5.6 shall not extend to any such information that:

          (a)  is already publicly known;

          (a)  has become  publicly  known without any fault of the Purchaser or
               anyone to whom the  Purchaser  has made  disclosure in compliance
               with the terms of this Section 5.6; or

          (b)  is required to be disclosed to any  governmental  authorities  or
               courts of law as a result of  operation  of law,  regulation,  or
               court order;  provided,  however,  that the Purchaser  shall have
               first given  prompt  written  notice of such  requirement  to the
               Company  (if  permissible)  and  cooperates  with the  Company to
               restrict such  disclosure  and/or obtain  confidential  treatment
               thereof.

The foregoing  notwithstanding,  the Purchaser may disclose such  information to
each of its  directors,  officers,  employees,  partners  (including its limited
partners),  members, managers and representatives,  which representatives have a
need to know such information;  provided that the Purchaser informs such persons
of the  restrictions  set  forth  in  this  Section  5.6  with  respect  to such
information and such persons agree to comply with the provisions of this Section
5.6. The  Purchaser  further  agrees to give prompt notice to the Company of any
disclosure made by the Purchaser or any of its directors,  officers,  employees,
partners (including limited partners),  members,  managers or representatives in
breach of this Section 5.6, to the extent the  Purchaser  has  knowledge of such
disclosure;  provided  that the  Purchaser  shall have no  liability  for losses
incurred  by  the  Company  or  any  of  its  directors,   officers,  employees,
stockholders or  representatives  solely as the result of the Company's failure,
following  its actual  receipt of notice from the  Purchaser  of  disclosure  of
information in breach of this Agreement, to make prompt public disclosure of the
information so disclosed. For purposes of this Section 5.6, the knowledge of the
Purchaser  shall mean the actual  knowledge of Peter B. Yunich or any successors
to him as Managing Partner of the Purchaser.
