      WHEREAS, as a material inducement to the Pledgees to enter into the
Purchase Agreement, the Pledgees have required and the Pledgor has agreed (i) to

successors, endorsees, transferees or assigns a security interest in the number

absolutely, unconditionally and irrevocably guarantees to the Pledgees, their
successors, endorsees, transferees and assigns the due and punctual performance
and payment of the Obligations owing to the Pledgees, their successors,
endorsees, transferees or assigns when due, all at the time and place and in the
amount and manner prescribed in, and otherwise in accordance with, the
Transaction Documents, regardless of any defense or set-off counterclaim which
the Company or any other person may have or assert, and regardless of whether or
not the Pledgees or anyone on behalf of the Pledgees shall have instituted any
suit, action or proceeding or exhausted its remedies or taken any steps to
enforce any rights against the Company or any other person to compel any such
performance or observance or to collect all or part of any such amount, either
pursuant to the provisions of the Transaction Documents or at law or in equity,
and regardless of any other condition or contingency. The Pledgor shall have no
obligation whatsoever to the Pledgees beyond the Collateral pledged for the
Obligations set forth herein.



<PAGE>

      2. Waiver of Demand. The Pledgor hereby unconditionally: (i) waives any
requirement that the Pledgees, in the event of a breach in any material respect
by the Company of any of its representations or warranties in the Transaction
Documents, first make demand upon, or seek to enforce remedies against, the
Company or any other person before demanding payment of enforcement hereunder;
(ii) covenants that this Agreement will not be discharged except by complete
performance of all the Obligations to the extent of the Collateral; (iii) agrees
that this Agreement shall remain in full force and effect without regard to, and
shall not be affected or impaired, without limitation, by, any invalidity,
irregularity or unenforceability in whole or in part of the Transaction
Documents or any limitation on the liability of the Company thereunder, or any
limitation on the method or terms of payment thereunder which may now or
hereafter be caused or imposed in any manner whatsoever; and (iv) waives
diligence, presentment and protest with respect to, and notice of default in the
performance or payment of any Obligation by the Company under or in connection
with the Transaction Documents.

      3. Release. The obligations, covenants, agreements and duties of the
Pledgor hereunder shall not be released, affected or impaired by any assignment
or transfer, in whole or in part, of the Transaction Documents or any
Obligation, although made without notice to or the consent of the Pledgor, or
any waiver by the Pledgees, or by any other person, of the performance or
observance by the Company or the Pledgor of any of the agreements, covenants,
terms or conditions contained in the Transaction Documents, or any indulgence in
or the extension of the time or renewal thereof, or the modification or
amendment (whether material or otherwise), or the voluntary or involuntary
liquidation, sale or other disposition of all or any portion of the stock or
assets of the Company or the Pledgor, or any receivership, insolvency,
bankruptcy, reorganization, or other similar proceedings, affecting the Company
or the Pledgor or any assets of the Company or the Pledgor, or the release of
any proper from any security for any Obligation, or the impairment of any such
property or security, or the release or discharge of the Company or the Pledgor
from the performance or observance of any agreement, covenant, term or condition
contained in or arising out of the Transaction Documents by operation of law, or
the merger or consolidation of the Company, or any other cause, whether similar
or dissimilar to the foregoing.

      4. Subrogation.

            (a) Unless and until complete performance of all the Obligations to
the extent of the Collateral, the Pledgor shall not be entitled to exercise any
right of subrogation to any of the rights of the Pledgees against the Company or
any collateral security or guaranty held by the Pledgees for the payment or
performance of the Obligations, nor shall the Pledgor seek any reimbursement
from the Company in respect of payments made by the Pledgor hereunder.

            (b) In the extent that the Pledgor shall become obligated to perform
or pay any sums hereunder, or in the event that for any reason the Company is
now or shall hereafter become indebted to the Pledgor, the amount of such sum
shall at all times be subordinate as to lien, time of payment and in all other
respects, to the amounts owing to the Pledgees under the Transaction Documents
and the Pledgor shall not enforce or receive payment thereof until all
Obligations due to the Pledgees under the Transaction have been performed or
paid. Nothing herein contained is intended or shall be construed to give to the
Pledgor any right of subrogation in or under the Transaction Documents, or any
right to participate in any way therein, or in any right, title or interest in
the assets of the Pledgees.



                                       2

      5. Security. As collateral security for the punctual payment and
performance, when due, by the Company of all the Obligations, the Pledgor,
subject to the Loan, hereby pledges with, hypothecates, transfers and assigns to
the Pledgees all of the Shares and all proceeds, shares and other securities
received, receivable or otherwise distributed in respect of or in exchange for
the Shares, including, without limitation, any shares and other securities into
which such Shares may be convertible or exchangeable (collectively, the
"Additional Collateral" and together with the Shares, the "Collateral"). Upon
repayment of the Loan and delivery of the certificates representing the Shares
by the Bank to the Pledgor, the Pledgor shall deliver to the Pledgees the
certificate(s) representing the Shares, stamped with a bank medallion guarantee,
along with a stock transfer power duly executed in blank by the Pledgor, to be
held by the Pledgees as security. Any Collateral received by the Pledgor on or
after the date that the Loan shall have been satisfied shall be immediately
delivered to the Pledgees together with any executed stock powers or other
transfer documents requested by the Pledgees, which request may be made at any
time prior to the date when the Obligations shall have been paid and otherwise
satisfied in full.

      6. Voting Power, Dividends, Etc. and other Agreements.

            (a) Unless and until an Event of Default (as set forth in Section 7
hereof) has occurred, the Pledgor shall be entitled to:

                  (i) Exercise all voting and/or consensual powers pertaining to
            the Collateral, or any part thereof, for all purposes;

                  (ii) Receive and retain dividends paid with respect to the
            Collateral; and

                  (iii) Receive the benefits of any income tax deductions
            available to the Pledgor as a shareholder of the Company.

            (b) The Pledgor agrees that it will not sell, assign, transfer,
pledge, hypothecate, encumber or otherwise dispose of the Collateral.

            (c) The Pledgor and the Company jointly and severally agree to pay
all costs including all reasonable attorneys' fees and disbursements incurred by
the Pledgees in enforcing this Agreement in accordance with its terms.

      7. Default and Remedies.

            (a) For the purposes of this Agreement, "Event of Default" shall
mean:

                  (i) default in or under any of the Obligations after the
            expiration, without cure, of any applicable cure period;

                  (ii) a breach in any material respect by the Company of any of
            its representations or warranties in the Transaction Documents; or

                  (iii) a breach in any material respect by the Pledgor of any
            of its representations or warranties in this Agreement.

            (b) the Pledgees shall have the following rights upon the repayment
of the Loan and any Event of Default:

                  (i) the rights and remedies provided by the Uniform Commercial
            Code as adopted by the State of New York (the "UCC") (as said law
            may at any time be amended);

                  (ii) the right to receive and retain all dividends, payments
            and other distributions of any kind upon any or all of the
            Collateral;

                  (iii) the right to cause any or all of the Collateral to be
            transferred to its own name or to the name of its designee and have
            such transfer recorded in any place or places deemed appropriate by
            the Pledgees; and

                  (iv) the right to sell, at a public or private sale, the
            Collateral or any part thereof for cash, upon credit or for future
            delivery, and at such price or prices in accordance with the UCC (as
            such law may be amended from time to time). Upon any such sale the
            Pledgees shall have the right to deliver, assign and transfer to the
            purchaser thereof the Collateral so sold. The Pledgees shall give
            the Pledgor not less than ten (10) days' written notice of its
            intention to make any such sale. Any such sale, shall be held at
            such time or times during ordinary business hours and at such place
            or places as the Pledgees may fix in the notice of such sale. The
            Pledgees may adjourn or cancel any sale or cause the same to be
            adjourned from time to time by announcement at the time and place
            fixed for the sale, and such sale may be made at any time or place
            to which the same may be so adjourned. In case of any sale of all or
            any part of the Collateral upon terms calling for payments in the
            future, any Collateral so sold may be retained by the Pledgees until
            the selling price is paid by the purchaser thereof, but the Pledgees
            shall incur no liability in the case of the failure of such
            purchaser to take up and pay for the Collateral so sold and, in the
            case of such failure, such Collateral may again be sold upon like
            notice. The Pledgees, however, instead of exercising the power of
            sale herein conferred upon them, may proceed by a suit or suits at
            law or in equity to foreclose the security interest and sell the
            Collateral, or any portion thereof, under a judgment or decree of a
            court or courts of competent jurisdiction, the Pledgor having been
            given due notice of all such action. The Pledgees shall incur no
            liability as a result of a sale of the Collateral or any part
            thereof. All proceeds of any such sale, after deducting the
            reasonable expenses and reasonable attorneys' fees incurred in
            connection with such sale, shall be applied in reduction of the
            Obligations, and the remainder, if any, shall be paid to the
            Pledgor.



                                       4
<PAGE>

      8. Application of Proceeds; Release. The proceeds of any sale or
enforcement of or against all or any part of the Collateral, and any other cash
or collateral at the time held by the Pledgees hereunder, shall be applied by
the Pledgees first to the payment of the reasonable costs of any such sale or
enforcement, then to reimburse the Pledgees for any damages, costs or expenses
incurred by the Pledgees as a result of an Event of Default, then to the payment
of the principal amount or stated valued (as applicable) of, and interest or
dividends (as applicable) and any other payments due in respect of, the
Obligations. The remainder, if any, shall be paid to the Pledgor. As used in
this Agreement, "proceeds" shall mean cash, securities and other property
realized in respect of, and distributions in kind of, the Collateral, including
any thereof received under any reorganization, liquidation or adjustment of debt
of any issuer of securities included in the Collateral.

      9. Representations and Warranties.

            (a) The Pledgor hereby represents and warrants to the Pledgees that:

                  (i) subject to the security interest held by the Bank in the
            Shares, the Pledgor has full power and authority and legal right to
            pledge the Collateral to the Pledgees pursuant to this Agreement and
            this Agreement constitutes a legal, valid and binding obligation of
            the Pledgor, enforceable in accordance with its terms.

                  (ii) subject to the security interest held by the Bank in the
            Shares, the execution, delivery and performance of this Agreement
            and other instruments contemplated herein will not violate any
            provision of any order or decree of any court or governmental
            instrumentality or of any mortgage, indenture, contract or other
            agreement to which the Pledgor is a party or by which the Pledgor
            and the Collateral may be bound, and will not result in the creation
            or imposition of any lien, charge or encumbrance on, or security
            interest in, any of the Pledgor's properties pursuant to the
            provisions of such mortgage, indenture, contract or other agreement.

                  (iii) the Pledgor is the sole record and beneficial owner of
            all of the Shares; and

                  (iv) subject to the security interest held by the Bank in the
            Shares, the Pledgor owns the Collateral free and clear of all Liens.

            (b) The Company represents and warrants to the Pledgees that:

                  (i) it has no knowledge that any of the representations or
            warranties of the Pledgor herein are incorrect or false in any
            material respect;



                                       5
<PAGE>

                  (ii) all of the Shares were validly issued, fully paid and
            non-assessable; and

                  (iii) the Pledgor is the record holder of the Shares.

      10. No Waiver; No Election of Remedies. No failure on the part of the
Pledgees to exercise, and no delay in exercising, any right, power or remedy
hereunder shall operate as a waiver thereof; nor shall any single or partial
exercise by the Pledgees of any right, power or remedy preclude any other or
further exercise thereof or the exercise of any other right, power or remedy.
The remedies herein provided are cumulative and are not exclusive of any
remedies provided by law. In addition, the exercise of any right or remedy of
the Pledgees at law or equity or under this Agreement or any of the documents
shall not be deemed to be an election of Pledgee's rights or remedies under such
documents or at law or equity.

      11. Termination. This Agreement shall terminate on the date on which all
Obligations have been performed, satisfied, paid or discharged in full.

      12. Further Assurances. The parties hereto agree that, from time to time
upon the written request of any party hereto, they will execute and deliver such
further documents and do such other acts and things as such party may reasonably
request in order fully to effect the purposes of this Agreement. The Pledgees
acknowledge that they are aware that Pledgor shall have no obligations
whatsoever to the Pledgees beyond the Collateral pledged for the Obligations set
forth herein, and no request for further assurance may or shall increase such
Obligations.

      13. Miscellaneous.

            (a) Modification. This Agreement contains the entire understanding
between the parties with respect to the subject matter hereof and specifically
incorporates all prior oral and written agreements relating to the subject
matter hereof. No portion or provision of this Agreement may be changed,
modified, amended, waived, supplemented, discharged, canceled or terminated
orally or by any course of dealing, or in any manner other than by an agreement
