Shares hereunder to the extent that, giving effect to such proposed
acquisition, the beneficial ownership of the Common Stock by the Purchaser
(together with its affiliates and any other Persons whose beneficial
ownership of Common Stock would be aggregated with the Purchaser's for
purposes of Section 13(d) of the Securities Exchange Act of 1934, as amended
(the "Exchange Act")), would exceed 9% of the total number of issued and
outstanding shares of Common Stock (including for such purpose the shares of

Shares being acquired on such Settlement Date, and (B) a certificate,
executed by the President of the Company, to the effect that the Company has
complied with and is in compliance with all of the conditions set forth in

the Purchaser, if on a Settlement Date, the Company fails to deliver to such
Purchaser's DTC Account the number of Shares being acquired on such
Settlement Date, and if the Purchaser purchases (in an open market
transaction or otherwise) shares of Common Stock to deliver in satisfaction
of a sale by the Purchaser of the shares that the Purchaser anticipated
receiving from the Company (a "Buy-In"), then, in the Purchaser's sole
discretion, the Company shall, within three Trading Days after the
Purchaser's request, either (i) pay cash to the Purchaser in an amount equal
to the Purchaser's total purchase price (including brokerage commissions, if
any) for the shares of Common Stock so purchased (the "Buy-In Price"), at
which point the Company's obligation to deliver such Shares shall terminate,
or (ii) promptly honor its obligation to deliver to the Purchaser a
certificate or certificates representing such Common Stock and pay cash to
the Purchaser in an amount equal to the excess (if any) of the Buy-In Price

Closing Price on the date of the event giving rise to the Company's
obligation to deliver such certificate.

                  (k)     Acknowledgment Regarding Purchaser's Purchase of
                          ------------------------------------------------
Shares. The Company acknowledges and agrees that the Purchaser is acting
------
solely in the capacity of an arm's length purchaser with respect to this
Agreement and the transactions contemplated hereby. The Company further
acknowledges that Purchaser is not acting as a financial advisor or
fiduciary of the Company (or in any similar capacity) with respect to this
Agreement and the transactions contemplated hereby and any advice given by
the Purchaser or any of its representatives or agents in connection with
this Agreement and the transactions contemplated hereby is merely incidental
to the Purchaser's purchase of the Shares. The Company further represents to
the Purchaser that the Company's decision to enter into this Agreement has
been based solely on the independent evaluation of the proposed transactions
by the Company and its representatives.

                  4.      Representations and Warranties of the Purchaser.
                          -----------------------------------------------

corporation duly incorporated, validly existing and in good standing under
the laws of its jurisdiction of incorporation with the requisite corporate
power and authority to own and use its properties and assets and to carry on
its business as currently conducted, except where the failure to do so would
not reasonably be expected to have a material adverse effect on the
Purchaser or the transactions contemplated hereby. The Purchaser is duly
qualified to conduct business and is in good standing as a foreign
corporation or other entity in each jurisdiction in which the nature of the
business conducted or property owned by it makes such qualification
necessary, except where the failure to do so would not reasonably be
expected to have a material adverse effect on the Purchaser or the
transaction contemplated hereby. The Purchaser has the requisite power and
authority to enter into and to consummate the transactions contemplated by
this Agreement and otherwise to carry out its obligations thereunder. The
execution and delivery of this Agreement by the Purchaser and the
consummation by it of the transaction contemplated hereby have been

<PAGE>
<PAGE>

duly authorized by all necessary action on the part of the Purchaser. This
Agreement has been duly executed by the Purchaser and, when delivered in
accordance with the terms hereof, and assuming the valid execution hereof by
the Company, will constitute the valid and binding obligation of the
Purchaser enforceable against it in accordance with its terms, except (a) as
such enforceability may be limited by bankruptcy, insolvency, reorganization
or similar laws affecting creditors' rights generally, (b) as enforceability
of any indemnification and contribution provisions may be limited under the
federal and state securities laws and public policy, and (c) that the remedy
of specific performance and injunctive and other forms of equitable relief
may be subject to equitable defenses and to the discretion of the court
before which any proceeding therefor may be brought.

                  (b)     Other Agreements; Status of Purchaser. The Purchaser
                          -------------------------------------

be material non-public information unless the Purchaser has agreed in
writing to receive such information prior to such divulgence. Neither the
Company nor the Purchaser will issue any press release or make any other
public announcement relating to this Agreement unless the form thereof is
mutually agreed to by the Company and the Purchaser, or if the Company is
advised in writing by its counsel that such press release or public
announcement is required by law. Except with respect to the press release to

8-K to furnish an opinion of counsel as to the legality of the Shares, the
Company shall not publicly disclose the name of the Purchaser, or include
the name of the Purchaser in any filing with the Commission or any
regulatory agency or trading market, without the prior written consent of
the Purchaser, except to the extent such disclosure is required by law or
trading market regulations, in which case the Company shall provide the
Purchaser with prior notice of such disclosure.

                  6.      RESERVATION AND LISTING OF SHARES. The Company shall

                                    hereto.

                  (d)     Governing Law. All questions concerning the
                          -------------
construction, validity, enforcement and interpretation of this Agreement
will be governed by and construed and enforced in accordance with the
internal laws of the State of New York, without regard to the principles of
conflict of laws thereof. Each party agrees that all legal proceedings
concerning the interpretations, enforcement and defense of the transactions
contemplated by this Agreement (whether brought against a party hereto or
its respective affiliates, directors, officers, shareholders, employees or
agents) will be exclusively commenced in the state and federal courts
sitting in the City of New York, Borough of Manhattan. Each party
irrevocably submits to the exclusive jurisdiction of the state and federal
courts sitting in the City of New York, Borough of Manhattan for the
adjudication of any dispute hereunder, and irrevocably waives, and agrees
not to assert in any suit, action or proceeding, any claim that it is not
personally subject to the jurisdiction of any such court or that such courts
are an improper or inconvenient forum. Each party hereto hereby irrevocably
waives personal service of process and consents to process being served in
any such suit, action or proceeding by mailing a copy thereof via registered
or certified mail or overnight delivery (with evidence of delivery) to such
party at the address in effect for notices to it under this Agreement and
agrees that such service will constitute good and sufficient service of
process and notice thereof. Nothing contained herein will be deemed to limit

party irrevocably waives, to the fullest extent permitted by applicable law,
any and all right to trial by jury in any legal proceeding arising out of or
relating to this Agreement or the transactions contemplated hereby. If
either party shall commence an action or proceeding to enforce any
provisions of this Agreement, then the prevailing party in such action or
proceeding will be reimbursed by the other party for its reasonable
attorneys fees and other reasonable costs and expenses incurred with the
investigation, preparation and prosecution of such action or proceeding.

                          --------
all rights provided herein or granted by law, including recovery of damages,
the Purchaser and the Company will each be entitled to specific performance
of the others obligations under this Agreement. In furtherance thereof, the
parties agree that monetary damages may not be adequate compensation for any
loss incurred by reason of any such breach and hereby agrees to waive in any
action for specific performance of any such obligation the defense that a
remedy at law would be adequate.

                  (f)     Execution. This Agreement may be executed in two or
                          ---------
more counterparts, all of which when taken together shall be considered one
and the same agreement and shall become effective when counterparts have
been signed by each party and delivered to the other party, it being
understood that both parties need not sign the same counterpart.

                  (g)     Assignment. Neither party shall assign this Agreement
                          ----------
without the prior written consent of the other party hereto.

                  (h)     Adjustments in Share Numbers and Prices. In the event
                          ---------------------------------------
of any stock split, subdivision, dividend or distribution payable in shares
of Common Stock (or other securities or rights convertible into, or
entitling the holder thereof to receive directly or indirectly shares of
Common Stock), combination or other similar recapitalization or event
occurring after the date hereof, each reference in this Agreement to a
number of shares or a price per share shall be amended to appropriately
account for such event.

                                 EXHIBIT `A'

                          TERMS OF INDEMNIFICATION

         (a) INDEMNIFICATION BY THE COMPANY. The Company will indemnify and
             ------------------------------
hold harmless the Purchaser and any Related Persons, from and against any
losses, claims, damages, liabilities, costs and expenses (including, without
limitation, reasonable costs of defense and investigation and all attorneys'
fees and expenses) to which the Purchaser and the officers, directors,
employees and agents of the Purchaser, and each person, if any, who controls
the Purchaser may become subject, under the Securities Act or otherwise,
insofar as such losses, claims, damages, liabilities and expenses (or
actions in respect thereof) arise out of or are based upon: (i) any untrue
statement or alleged untrue statement of a material fact contained, or
incorporated by reference, in the Company Registration Statement or any
amendment or supplement to the Registration Statement, or (ii) the omission
or alleged omission to state in that Registration Statement a material fact
required to be stated therein or necessary to make the statements therein
not misleading (an "INDEMNIFIABLE MATTER"). The Company will reimburse the
Purchaser and the officers, directors, employees and agents of the Purchaser
and each such controlling person promptly upon demand for any legal or other
costs or expenses reasonably incurred by the Purchaser and the officers,
directors, employees and agents of the Purchaser or the controlling person
in investigating, defending against, or preparing to defend against any
claim relating to an Indemnifiable Matter, except that the Company will not
be liable to the extent such claim, suit or proceeding which results in a
loss, claim, damage, liability or expense arises out of, or is based upon,
an untrue statement, alleged untrue statement, omission or alleged omission,
included in the Supplement in reliance upon, and in conformity with, written
information furnished by the Purchaser to the Company for inclusion in the
Supplement.

         (b) CONTRIBUTION. If for any reason the indemnification provided
             ------------
for in this Agreement is not available to, or is not sufficient to hold
harmless, an indemnified party in respect of any loss, claim, damage,
liability, cost or expense referred to in Paragraph (a), each indemnifying
party will, in lieu of indemnifying the indemnified party, contribute to the
amount paid or payable by the indemnified party, contribute to the amount
paid or payable by the indemnified party as a result of the loss, claim,
damage, liability, cost or expense: (i) in the proportion which is
appropriate to reflect the relative benefits received by the indemnifying
party, on the one hand, and by the indemnified party, on the other hand,
from the sale of stock which is the subject of the claim, action, suit or
proceeding which resulted in the loss, claim, liability, cost or expense or
(ii) if that allocation is not permitted by applicable law, in such
proportion as is appropriate to reflect not only the relative benefits of
the sale of stock, but also the relative fault of the indemnifying party and
the indemnified party with respect to the statements or omissions which are
the subject of the claim, action, suit or proceeding that resulted in the
loss, claim, damage, liability, cost or expense as well as any other
relevant equitable considerations.
