         (b) payment of all sums advanced upon an Event of Default or in

instrument now or hereafter evidencing or securing any of the foregoing.

         Section 4. Delivery of Collateral; Issuance of Additional Shares.

         (a) All certificates or instruments representing or evidencing the
Pledged Shares shall be delivered to the Secured Party on the date hereof (or if
such certificates or instruments are not in the possession of the Pledgor,
immediately upon the acquisition thereof by Pledgor, but in no event later than
fifteen (15) days after the date hereof), and shall be held by the Secured Party
pursuant hereto at all times hereafter, and all certificates and instruments
representing or evidencing securities acquired by the Pledgor after the date
hereof and constituting Pledged Collateral hereunder shall be delivered to the
Secured Party immediately upon, and held by the Secured Party at all times

after the date of such acquisition). All such certificates or instruments shall
be in suitable form for transfer by delivery, or shall be accompanied by duly
executed instruments of transfer or assignment in blank, all in form and

         (b) Upon the occurrence and during the continuance of an Event of
Default hereunder, the Secured Party shall have the right, at any time in its
discretion, to transfer to or to register on the books of Secured Party in the

Collateral (with, in the discretion of the Secured Party, such transfer or
registration expressly empowering the Secured Party to vote shares of stock
included in the Pledged Collateral), subject only to the revocable rights
specified in Section 7(a). In addition, the Secured Party shall have the right
at any time to exchange certificates or instruments representing or evidencing
Pledged Collateral for certificates or instruments of smaller or larger

         Section 5. Representations and Warranties; Certain Covenants.

         (a) Pledgor hereby represents and warrants that Pledgor is the legal
and equitable owner of the Pledged Collateral free and clear of all liens,
charges, encumbrances and security interests of every kind and nature, other
than Permitted Encumbrances (as defined below).


                                       2
<PAGE>
         (b) Pledgor covenants that:

                  (i) except for the Security Interest granted hereby and the
         security interests permitted under or otherwise contemplated hereby
         ("Permitted Encumbrances"), Pledgor will not create, assume, incur or
         permit to exist or to be created, assumed or incurred, directly, or
         indirectly, any lien of any kind on, or any repurchase agreement with
         respect to, the Pledged Collateral, and will defend the Pledged
         Collateral against, and take such action as is necessary to remove, any
         such lien, and will defend the Security Interest against the claims and
         demands of all persons; and

                  (ii) Pledgor shall advise the Secured Party promptly, in
         reasonable detail, of any lien or claim made or asserted against any of
         the Pledged Collateral; and of the occurrence of any other event which
         would have a material adverse effect on the enforceability of the
         Security Interest created hereunder.

         Section 6. Further Assurances. Pledgor agrees that at any time and from
time to time, at the expense of Pledgor, Pledgor will promptly execute and
deliver all further instruments and documents, and take all further action that
the Secured Party may reasonably request, in order to perfect and protect the
Security Interest granted or intended to be granted hereby or to enable the
Secured Party to exercise and enforce its rights and remedies hereunder with
respect to any Pledged Collateral.

         Section 7. Voting Rights; Dividends; Etc.

         (a) So long as no Event of Default hereunder shall have occurred and be
continuing:

                  (i) Pledgor shall be entitled to exercise any and all voting
         and other consensual rights (if any) pertaining to the Pledged
         Collateral or any part thereof for any purpose not prohibited by the
         terms of this Agreement; and

                  (ii) except as otherwise provided in Sections 4(b) and 7(c)
         hereof, Pledgor shall be entitled to receive and retain any dividends,
         cash and other property from time to time paid, payable or otherwise
         distributed in respect of the Pledged Collateral.

         (b) Pledgor hereby irrevocably appoints the Secured Party as Pledgor's
proxyholder with respect to the Pledged Shares and any other voting securities
forming a part of the Pledged Collateral with full power and authority to vote
such Pledged Shares and other voting securities and to otherwise act with
respect to such Pledged Shares or other voting securities on behalf of such
Pledgor, provided that this proxy shall only be operative upon the occurrence of
an Event of Default and so long as such Event of Default continues. Such proxy
shall be irrevocable for so long as any of the Secured Obligations remain in
existence. Pledgor shall execute and deliver (or cause to be executed and
delivered) to the Secured Party all proxies and other instruments as the Secured
Party may reasonably request for the purpose of enabling the Secured Party to
exercise the voting and other rights which it is entitled to exercise pursuant
to this Section 7(b); and

         (c) Upon the occurrence and during the continuance of an Event of
Default hereunder, all rights of the Pledgor to receive and retain dividends,
cash and other property, which they would otherwise be authorized to receive and
retain pursuant to Section 7(a)(ii), shall


                                       3
<PAGE>
cease and all such rights shall thereupon be vested in the Secured Party, who
shall thereupon have the sole right to receive and hold as Pledged Collateral
such dividends, cash and other property. All cash and other property received by
Pledgor contrary to the provisions of this Section 7(c) shall be received in
trust for the benefit of the Secured Party, shall be segregated from other
property or funds of Pledgor and shall be forthwith delivered to the Secured
Party as Pledged Collateral in the same form as so received (with any necessary
transfer documents or endorsements).

         Section 8. Restrictions on Transfer; Dispositions and Release of
Collateral. Pledgor covenants that Pledgor shall not enter into or perform any
agreement to sell, lease, transfer or otherwise dispose of all or any part of
the Pledged Collateral unless the Security Interest in such Pledged Collateral
shall have been released in accordance with the provisions of Section 17 hereof.

         Section 9. Reasonable Care. The Secured Party shall be deemed to have
exercised reasonable care in the custody and preservation of the Pledged
Collateral in its possession if the Pledged Collateral is accorded treatment
substantially equal to that which the Secured Party accords its own property, it
being understood that the Secured Party shall have no responsibility for (a)
ascertaining or taking action with respect to calls, conversions, exchanges,
maturities, tenders or other matters relative to any Pledged Collateral, whether
or not the Secured Party has or is deemed to have knowledge of such matters,
unless reasonably requested in writing to do so by Pledgor, or (b) taking any
necessary steps (other than steps taken in accordance with the standard of care
set forth above to maintain possession of the Pledged Collateral) to preserve
rights against any parties with respect to any Pledged Collateral.

         Section 10. Secured Party Appointed Attorney-in-Fact. Pledgor hereby
irrevocably appoints the Secured Party Pledgor's attorney-in-fact, with full
authority in the place and stead of Pledgor and in Pledgor's name or otherwise,
if Secured Party elects, upon an Event of Default, to take any action and to
execute any instrument which the Secured Party may deem reasonably necessary or
advisable to accomplish the purposes of this Agreement, including, without
limitation, to receive, endorse and collect all instruments made payable to
Pledgor representing any dividend, interest payment or other distribution in
respect of the Pledged Collateral or any part thereof and to give full discharge
for the same, when and to the extent permitted by this Agreement.

         Section 11. Secured Party May Perform. Upon the occurrence and during
the continuance of an Event of Default hereunder (including an Event of Default
resulting from a failure to perform any agreement contained herein), if Pledgor
fails to perform any agreement contained herein, the Secured Party may itself
perform, or cause performance of, such agreement, and the expenses of the
Secured Party incurred in connection therewith shall be payable by Pledgor.

         Section 12. Events of Default; Remedies.

         (a) The occurrence of any of the following events shall constitute an
event of default ("Event of Default") hereunder:


                                       4
<PAGE>
                  (i) Any Event of Default (as defined in the Note) shall have
         occurred, which Event of Default shall not be waived or, if capable of
         being cured, shall not be cured within the respective periods provided
         in such Note;

                  (ii) Pledgor fails, breaches or defaults in the payment or
         performance of any of the obligations, covenants or conditions
         contained in this Agreement or specified in the Plan; or

                  (iii) Any statement, representation or warranty made or
         furnished by Pledgor in connection with this Agreement or any other
         writing delivered to the Secured Party in connection with this
         Agreement and the transactions contemplated herein is false, misleading
         or erroneous in any material respect when made.

         (b) Upon or after the occurrence of an Event of Default:

                  (i) The Secured Party may exercise (in compliance with all
         applicable securities laws) in respect of the Pledged Collateral, in
         addition to other rights, powers and remedies provided for herein or
         otherwise available to it, all the rights, powers and remedies of a
         secured party after default under the Uniform Commercial Code in force
         and effect in each state in which such rights, powers and remedies are
         asserted, all of which rights, powers and remedies shall be cumulative
         and not exclusive, to the extent permitted by applicable law.

                  (ii) The Secured Party may also, without notice except as
         specified below, sell the Pledged Collateral or any part thereof in one
         or more parcels at public or private sale, at any exchange, over the
         counter or at any of the Secured Party's offices or elsewhere, for
         cash, on credit or for future delivery, and at such price or prices and
         upon such other terms as may be commercially reasonable or otherwise in
         such manner as necessary to comply with applicable federal and state
         securities laws. Pledgor agrees that the Secured Party shall not be
         required to register or qualify any of the Pledged Collateral under
         applicable state or federal securities laws in connection with any such
         sale if the sale is effected in a manner that complies with all
         applicable federal and state securities laws. The Secured Party shall
         be authorized at any such sale (if it deems it advisable to do so) to
         restrict the prospective bidders or purchasers to persons who will
         represent and agree that they are purchasing the Pledged Collateral for
         their own account, for investment and not with a view to the
         distribution thereof. Upon consummation of any such sale the Secured
         Party shall have the right to assign, transfer and deliver to the
         purchaser or purchasers at any such sale, and such purchasers shall
         hold, the property sold absolutely free from any claim or right on the
         part of the Pledgor, and Pledgor hereby waives (to the extent permitted
         by law) all rights of redemption, stay or appraisal which he now has or
         may at any time in the future have under applicable law now existing or
         hereafter enacted.

                  (iii) The Secured Party shall give the Pledgor at least ten
         (10) days', (or such longer period as shall be specified by applicable
         law) notice of the time and place of any public sale or the time after
         which any private sale is to be made, which Pledgor agrees shall
         constitute commercially reasonable notification. At any such public
         sale and (to the


                                       5
<PAGE>
         extent permitted by law) at any such private sale, the Secured Party
         may bid, in whole or in part, in the form of cancellation of Secured
         Obligations, and the Secured Party may purchase the whole or any part
         of the Pledged Collateral. The Secured Party shall not be obligated to
         make any sale of Pledged Collateral regardless of notice of sale having
         been given. The Secured Party may adjourn any public or private sale
         from time to time by announcement at the time and place fixed therefor,
         and such sale may, without further notice, be made at the time and
         place to which it was so adjourned.

                  (iv) If a sale of all or any part of the Pledged Collateral is
         made on credit or for future delivery, the Pledged Collateral so sold
         may be retained by the Secured Party until the sale price is paid by
         the purchaser or purchasers thereof, but the Secured Party shall not
         incur any liability in case any such purchaser or purchasers shall fail
         to take up and pay for the Pledged Collateral so sold and, in case of
         any such failure, such Pledged Collateral may be sold again upon like
         notice. Pledgor agrees to the maximum extent permitted by applicable
         law that any sale of the Pledged Collateral conducted by the Secured
         Party in accordance with the foregoing provisions of this Section shall
         be deemed to be a commercially reasonable sale under applicable law.

                  (v) As an alternative to exercising the power of sale herein
         conferred upon it, the Secured Party may proceed by a suit or suits at
         law or in equity to foreclose the Security Interest and to sell the
         Pledged Collateral, or any portion thereof, pursuant to a judgment or
         decree of a court or courts of competent jurisdiction.

                  (vi) Any cash held by the Secured Party as Pledged Collateral
         and all cash proceeds received by the Secured Party in respect of any
         sale of, collection from, or other realization upon all or any part of
         the Pledged Collateral shall be applied as follows: (a) first, to the
         payment to the Secured Party of the costs and expenses of retaking,
         holding and preparing for sale of the Pledged Collateral and any other
         fees, expenses, claims, demands, losses, judgments, damages and
         liabilities payable to the Secured Party pursuant to any provision
         hereof; and (b) second, in accordance with the provisions of the Note.

                  (vii) Any surplus of such cash or cash proceeds held by the
         Secured Party and remaining after payment in full of all the Secured
         Obligations shall be reassigned and redelivered as provided in Section
         17 hereof.

         Section 13. Security Interest Absolute. All rights of the Secured Party
hereunder, the Security Interest, and all obligations of the Pledgor hereunder,
shall be absolute and unconditional irrespective of:

         (a) any lack of validity or enforceability of the Note, any agreement
with respect to any of the Secured Obligations, or any other agreement or
instrument relating to any of the foregoing;

         (b) any change in the time, manner or place of payment of, or in any
other term of, all or any of the Secured Obligations, or any other amendment or
waiver of or any consent to and departure from the Note or any other agreement
or instrument;


                                       6
<PAGE>
         (c) any exchange, release or non-perfection of any other collateral, or
any release of, amendment to, waiver of, consent to or departure from any
guaranty, for all or any of the Secured Obligations; and

         (d) any other circumstance which might otherwise constitute a defense
available to, or a discharge of, Pledgor in respect of the Secured Obligations
or in respect of this Agreement.

         Section 14. Notices. All notices, demands, requests, and other
communications required or permitted hereunder shall be in writing and shall be
deemed to have been given (i) when presented personally or (ii) three (3)
business days after being deposited in a regularly maintained receptacle for the
United States Postal Service, postage prepaid, registered or certified, return

held by it hereunder, together with appropriate instruments of reassignment and
release as follows:

         (a) the Secured Party shall transfer or reassign and redeliver to
