                              W I T N E S S E T H :

                  WHEREAS, the authorized capital stock of the Corporation
consists of 30,000,000 shares of Common Stock, 100,000 shares of Class B

                  WHEREAS, subject to the terms and conditions hereof, the

placement of $3.5 million in aggregate value of shares of Common Stock.

                  (b) The purchase price per share for the Purchased Shares to

its best efforts to: (i) cause the Registration Statement to become effective
within one hundred fifty (150) days of the Closing Date, (ii) keep such
registration effective until the earlier of (a) the second anniversary of the
Closing Date, (b) such date as all of the Purchased Shares have been resold by

                         (d) The Corporation shall furnish to the Subscriber
upon request a reasonable number of copies of a supplement to or an amendment of
such prospectus as may be necessary in order to facilitate the public sale or
other disposition of all or any of the Purchased Shares held by the Subscriber.

                         (e) With a view to making available to the Subscriber
the benefits of Rule 144 promulgated under the Securities Act ("Rule 144") and
any other rule or regulation of the Securities and Exchange Commission that may

registration or pursuant to a registration on Form S-3, the Corporation

                                    (i) The Corporation agrees to indemnify and
hold harmless Subscriber from and against any losses, claims, damages or
liabilities (or actions or proceedings in respect thereof) to which such
Subscriber may become subject (under the Securities Act or otherwise) insofar as
such losses, claims, damages or liabilities (or actions or proceedings in
respect thereof) arise out of or are based upon, any untrue statement of a
material fact contained in the Registration Statement, on the effective date
thereof, or arise out of any failure by the Corporation to fulfill any
undertaking included in the Registration Statement, and the Corporation will, as
incurred, reimburse Subscriber for any legal or other expenses reasonably
incurred in investigating, defending or preparing to defend any such action,
proceeding or claim; provided, however, that the Corporation shall not be liable
in any such case to the extent that such loss, claim, damage or liability arises
out of or is based upon (a) an untrue statement made in such Registration
Statement in reliance upon and in conformity with written information furnished
to the Corporation by or on behalf of Subscriber specifically for use in
preparation of the Registration Statement, (b) the failure of Subscriber to

                                    (ii) Subscriber agrees to indemnify and hold
harmless the Corporation from and against any losses, claims, damages or
liabilities (or actions or proceedings in respect thereof) to which the
Corporation may become subject (under the Securities Act or otherwise) insofar
as such losses, claims, damages or liabilities (or actions or proceedings in
respect thereof) arise out of or are based upon (a) an untrue statement made in
such Registration Statement in reliance upon and in conformity with written
information furnished to the Corporation by or on behalf of Subscriber
specifically for use in preparation of the Registration Statement, provided,
however, that Subscriber shall not be liable in any such case for any untrue
statement included in any Prospectus which statement has been corrected, in
writing, by Subscriber and delivered to the Corporation before the sale from
which such loss occurred, (b) the failure of Subscriber to comply with the
covenants and agreements contained in this Agreement, or (c) any untrue
statement in any prospectus that is corrected in any subsequent Prospectus that
was delivered to the Subscriber prior to the pertinent sale or sales by the
Subscriber. Notwithstanding the foregoing, in no event shall the Subscriber to
liable to the Corporation under this Section 2 for any amounts in excess of the
net proceeds received by the Subscriber from the sale of the Purchased Shares
pursuant to the Registration Statement.

                                    (iii) Promptly after receipt by any
indemnified person of a notice of a claim or the beginning of any action in
respect of which indemnity is to be sought against an indemnifying person
pursuant to this Section 2, such indemnified person shall notify the
indemnifying person in writing of such claim or of the commencement of such
action, and, subject to the provisions hereinafter stated, in case any such
action shall be brought against an indemnified person and the indemnifying
person shall have been notified thereof, the indemnifying person shall be
entitled to participate therein, and, to the extent that it shall wish, to
assume the defense thereof, with counsel reasonably satisfactory to the
indemnified person. After notice from the indemnifying person to such
indemnified person of the indemnifying person's election to assume the defense
thereof, the indemnifying person shall not be liable to such indemnified person
for any legal expenses subsequently incurred by such indemnified person in
connection with the defense thereof, provided, however, that if there exists or
shall exist a conflict of interest that would make it inappropriate in the
reasonable judgment of the indemnified person for the same counsel to represent
both the indemnified person and such indemnifying person or any affiliate or
associate thereof, the indemnified person shall be entitled to retain its own
counsel at the expense of such indemnifying person.

                                    (iv) If the indemnification provided for in
this Section 2 is unavailable to or insufficient to hold harmless an indemnified
party under subsection (i) or (ii) above in respect of any losses, claims,
damages or liabilities (or actions or proceedings in respect thereof) referred
to therein, then each indemnifying party shall contribute to the amount paid or
payable by such indemnified party as result of such losses, claims, damages or
liabilities (or actions in respect thereof) in such proportion as is appropriate
to reflect the relative fault of the Corporation on the one hand and the
Subscriber on the other in connection with the statements or omissions which
resulted in such losses, claims, damages or liabilities (or actions in respect
thereof), as well as any other relevant equitable considerations. The relative
fault shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a

                                                                               5


material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Corporation on the one hand or the
Subscriber on the other and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The Corporation and the Subscriber agree that it would not be just and equitable
if contribution pursuant to this subsection (iv) were determined by pro rata
allocation or by any other method of allocation which does not take account of
the equitable considerations referred to above in this subsection (iv). The
amount paid or payable by an indemnified party as a result of the losses,
claims, damages, or liabilities (or actions in respect thereof) referred to
above in this subsection (iv) shall be deemed to include any legal or other
expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim. Notwithstanding the
provisions of this subsection (iv), Subscriber shall not be required to
contribute any amount in excess of the amount by which the net amount received
by the Subscriber from the sale of the Purchased Shares to which such loss
relates exceeds the amount of any damages which Subscriber has otherwise been
required to pay by reason of such untrue or alleged untrue statement or omission
or alleged omission. No person guilty of fraudulent misrepresentation (within
the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation.

                                   
                                    (v) The obligations of the Corporation and
the Subscriber under this Section 2 shall be in addition to any liability which
the Corporation and the Subscriber may otherwise have.

         3. REPRESENTATIONS AND WARRANTIES OF THE CORPORATION. The Corporation
hereby represents and warrants to the Subscriber, as of the date hereof and as

governmental authority or agency, in each case which is binding on the
Corporation or any of its Subsidiaries, or any agreement or instrument to which

outstanding shares of the Corporation's capital stock have been issued in

was filed or, in the case of the Confidential Memorandum, as of the date

(ii) the application of general principles of equity (regardless of whether such
enforceability is considered in a proceeding in equity or at law).

contemplated or compliance by the Subscriber with the terms and provisions
hereof will conflict with or result in a breach of, or require any consent
under, in the event that the Subscriber is a corporation, partnership or other
entity, the organizational documents and/or by-laws, and/or other documents of
similar import, as the case may be, of the Subscriber, or, with regard to any
Subscriber, any law, regulation, order, writ, injunction or decree of any court
or governmental authority or agency, in each case which is binding on the
Subscriber or any of its Subsidiaries, if any, or any agreement or instrument to
which the Subscriber or any of its Subsidiaries, if any, is a party or by which
any of them or any of their Property is bound or to which any of them is
subject, constitute a default under any such agreement or instrument.

                  (e) INVESTMENT REPRESENTATIONS. (i) In evaluating the
suitability of an investment in the Corporation, the Subscriber has not relied
upon any representation or warranty (oral or written) (except those expressly

                  thereof) or future or pro forma financial condition (or any
                  component thereof) of the Corporation and its Subsidiaries (or
                  any of them) or the future or pro forma business, operations
                  or affairs of the Corporation and its Subsidiaries (or any of
                  them);

                           (B) any future or pro forma rates of return in
                  respect of the Subscriber's investment in the Purchased Shares
                  or the future or pro forma value of such Purchased Shares; and

                           (C) any other information, statement or documents
                  heretofore delivered to or made available to the Subscriber or
                  its counsel, accountants, advisors, lenders, representatives
                  or affiliates with respect to the Corporation and its
                  Subsidiaries (or any of them) or the business, operations or
                  affairs of the Corporation and its Subsidiaries (or any of
                  them), except to the extent and as expressly covered by a
                  representation and warranty contained in Section 3 hereof.

shares and to make an informed investment decision with respect thereto.

                           (vi) The Subscriber is acquiring the Purchased Shares
solely for its own account for investment and not with a present view to, or for
sale in connection with, the distribution thereof within the meaning of the
Securities Act.

Corporation proposes to effect an exchange (the "Exchange") in which it will
issue Common Stock, at the Purchase Price per Purchased Share, in exchange for
(1) all of the issued and outstanding shares of its Preferred Stock 1997-A, with
an aggregate liquidation preference of $4 million (and all accrued and unpaid
dividends thereon on the date of the exchange) and (2) the retirement of $1
million in principal amount of certain subordinated debt, all held by corporate
affiliates of Paul J. Ramsay, the Chairman of the Corporation, (b) the
Corporation proposes to effect one or more additional private placements of its
Common Stock to investors other than the Subscriber and other than Luis E.
Lamela, the Chief Executive Officer of the Corporation (collectively, the "Other
Investors") and (c) in connection with the Exchange and the private placements
contemplated above, the Corporation intends to amend its Rights Agreement as set
forth in Exhibit A hereto.
