                            B.   Except for the security interests granted
          hereby, the Pledgor is, and as to Collateral acquired after the date
          hereof the Pledgor shall and will be at the time of acquisition, the
          record and beneficial owner and holder of the Collateral free from any
          adverse claim, security interest, pledge, encumbrance, lien, charge,
          or other right, title or interest of any person other than the
          Pledgee, and covenants that at all times the Collateral will be and
          remain free of all such adverse claims, security interests, pledges,
          encumbrances, liens, charges or other adverse interests by third
          parties. The Pledged Shares are free from and not otherwise subject to
          any voting agreements, voting trusts, proxies, options, preferential
          purchase rights or other right of any party to acquire all or any
          portion of the Pledged Shares.

                            C.   (i)  The Pledgor has full power and lawful
          authority to enter into this Agreement and to pledge the Collateral to
          the Pledgee and to grant to the Pledgee a first and prior security
          interest therein as herein provided, all of which have been duly
          authorized by all necessary corporate action.

                     (ii)   The execution and delivery and the performance
          hereof are not in contravention of any charter, articles of
          incorporation or by-law provision, or of any Instrument or undertaking
          to which the Pledgor is a party or by which the Pledgor or its
          property is bound.

                     (iii)  This Agreement constitutes the valid and legally
          binding obligation of the Pledgor enforceable in accordance with its
          terms.

                     (iv)   The Pledgor will defend the Collateral against all
          claims and demands of all persons at any time claiming the same or any
          interest therein.  Any officer or representative acting for or on

days prior written notice to the Pledgee.

                     (ii)   The preamble hereof states the correct legal name of
          the Pledgor and the Pledgor does not conduct business under any other
          name.  Pledgor shall not change its corporate name, nor do business
          under any name other than its current name, unless the Pledgor has
          delivered to

                                      164
<PAGE>

          the Pledgee written notice of such other names at least 30 days prior
          to the date of first use thereof by the Pledgor.

                 (e) (i)    The Pledgor has not heretofore agreed to or signed
any pledge, charge, financing statement or security agreement which covers any
of the Collateral, and no such pledge, charge, financing statement or security
agreement is now on file in any public office and the Pledgor has not heretofore
filed or inserted any entries or notations in the books or share registry of the
Pledgor or the Pledgor evidencing any pledge of the Collateral (other than such
financing statements, security agreements and share registry notations, if any,
of which both written notice and true and correct copies have heretofore been
given by the Pledgor to the Pledgee).

                     (ii)   As long as any amount remains unpaid on any of the
          Secured Obligations or under any agreement entered into in connection
          with the Secured Obligations, except as expressly permitted by any
          such agreement, (A) the Pledgor will not enter into or execute any
          pledge, charge, security agreement or financing statement covering the
          Collateral, other than those pledges, charges, security agreements and
          financing statements in favor of the Pledgee hereunder, (B) the
          Pledgor shall not file or consent to the filing of any pledge,
          financing statement or statements (or any documents or papers filed as
          such) covering the Collateral, other than financing statements in
          favor of the Pledgee hereunder, unless in any case the prior written
          consent of the Pledgee shall have been obtained, and further (C) the
          Pledgor shall not insert, file or make any notations in the books or
          share registry of the Pledgor evidencing any pledge of the Collateral,
          other than such entries and notations in favor of the Pledgee
          hereunder.

                     (iii)  The Pledgor authorizes the Pledgee to file, in its
          discretion, in jurisdictions where this authorization will be given
          effect, a financing statement, personal property security act filing
          or other instrument for filing required by any jurisdiction applicable
          to the Collateral signed only by the Pledgee covering the Collateral,
          and hereby appoints the Pledgee as the Pledgor's attorney-in-fact to
          sign and file any such financing statements or other instruments
          covering the Collateral.  At the request of the Pledgee, the Pledgor
          will join the Pledgee in executing such Instruments as the Pledgee may
          determine from time to time to be necessary or desirable under
          provisions of any applicable Uniform Commercial Code, Personal
          Property Security Act or other applicable laws in effect where the
          Collateral is located or where the Pledgor conducts business; without
          limiting the generality of the foregoing, the Pledgor agrees to join
          the Pledgee, at the Pledgee's request, in executing one or more
          financing statements or other Instruments in form satisfactory to the
          Pledgee, and the Pledgor will pay the costs of filing or recording the
          same in all public offices at any time and from time to time whenever

                                      165
<PAGE>

          filing or recording of any such financing statement or other
          Instrument is deemed by the Pledgee to be necessary or desirable.

                 IV.   Rights of the Pledgee and the Pledgor Related to
                       ------------------------------------------------
          Collateral.
          ----------

          The Pledgee may from time to time following the occurrence of an Event
of Default, as defined in the Note or the Purchase Agreement:

                            A.   Transfer any of the Collateral into the name of
          the Pledgee or its nominee.

                            B.   Notify parties obligated on any of the
          Collateral to make payment to the Pledgee of any amounts due or to
          become due thereunder.

                            C.   Subject to compliance with federal and state
          securities laws, enforce collection of any of the Collateral by suit
          or otherwise; surrender, release or exchange all or any part thereof,
          or compromise or extend or renew for any period (whether or not longer
          than the original period) any obligation of any nature of any party
          with respect thereto; and exercise all other rights of the Pledgor in
          any of the Collateral, except as hereinafter provided with respect to
          income from or interest on the Collateral and except that, prior to an
          Event of Default, the Pledgor may exercise its voting and consensual
          rights with respect to any Collateral constituting voting securities.

                            D.   Take possession or control of any proceeds of
          the Collateral.

          Until the occurrence of an Event of Default, the Pledgor shall have
the right to receive all income from or interest on the Collateral, and if the
Pledgee receives any such income or interest prior to the occurrence of an Event
of Default, the Pledgee shall pay the same promptly to the Pledgor, except that
in the case of securities or other property distributed by way of a dividend or
otherwise with respect to the Collateral, such securities or other property
shall be promptly delivered to the Pledgee to be held as Pledged Shares or other
Collateral hereunder.  Upon the occurrence of an Event of Default, the Pledgor
will not demand or receive any income from or interest on the Collateral, and if
the Pledgor receives any such income or interest without any demand by it, the
same shall be held by the Pledgor in trust for the Pledgee in the same medium in
which received, shall not be commingled with any assets of the Pledgor and shall
be delivered to the Pledgee in the form received, properly endorsed to permit
collection, not later than the next business day following the day of its
receipt.  The Pledgee may apply the net cash received from such income or
interest to payment of any of the Secured Obligations, provided that the Pledgee
shall account for and pay over to the Pledgor any such income or interest
remaining after payment in full of the Secured Obligations then outstanding.

                                      166
<PAGE>

          So long as no Event of Default shall have occurred, the Pledgor shall
be entitled to exercise any and all voting and other consensual rights
pertaining to the Collateral or any part thereof for any purpose not
inconsistent with the terms of this Agreement or the Purchase Agreement;
provided, however, that the Pledgor shall not exercise or refrain from
--------  -------
exercising any such right if, in the Pledgee's judgment, such action would have
a material adverse effect on the value of the Collateral or any part thereof;
and, provided, further, that the Pledgor shall give the Pledgee at least five
     --------  -------
days' written notice of the manner in which it intends to exercise, or the
reasons for refraining from exercising, any such rights.

          The Pledgee shall never be under any obligation to collect, attempt to
collect, protect or enforce the Collateral or any security therefor, which the
Pledgor agrees and undertakes to do at the Pledgor's expense, but the Pledgee
may do so in its discretion at any time after the occurrence of an Event of
Default and at such time the Pledgee shall have the right to take any steps by
judicial process or otherwise as it may deem proper to effect the collection of
all or any portion of the Collateral or to protect or to enforce the Collateral
or any security therefor.  All expenses (including, without limitation,
reasonable attorneys' fees and expenses) incurred or paid by the Pledgee in
connection with or incident to any such collection or attempt to collect the
Collateral or actions to protect or enforce the Collateral or any security
therefor shall be borne by the Pledgor or reimbursed by the Pledgor to the
Pledgee upon demand.  The proceeds received by the Pledgee as a result of any
such actions in collecting or enforcing or protecting the Collateral shall be
utilized by the Pledgee in accordance with Section 10 hereof.
                                           ----------

                 V.    Further Assurances.
                       -------------------

          The Pledgor agrees to take such actions and to execute such stock or
bond powers or other Instruments and such other or different writings as the
Pledgee may reasonably request further to perfect, confirm and assure the
Pledgee's security interest in the Collateral and irrevocably authorizes the
Pledgee, as Pledgor's agent and attorney-in-fact, to assist the Pledgee's
realization thereon upon the occurrence of an Event of Default including,
without limitation, the right to receive, indorse, and collect all instruments
made payable to the Pledgor representing any dividend, interest payment or other
distribution in respect of the Pledged Shares or any part thereof.

                 VI.  Events of Default.
                      ------------------

          The occurrence of an Event of Default under the Note shall constitute
an "Event of Default" hereunder.

                                      167

                 VII.  Rights and Remedies of the Pledgee Upon Default.
                       ------------------------------------------------

          If an Event of Default shall have occurred:

                            A.   The Pledgee shall have and may, subject to
          compliance with federal and state securities laws, exercise with
          reference to the Collateral and the Secured Obligations any and all of
          the rights and remedies of a secured party under the Uniform
          Commercial Code ("UCC"), and as otherwise granted herein or under any
          other applicable law now or hereafter in effect executed by the
          Pledgor, including, without limitation, the right and power to sell,
          at public or private sale or sales, or otherwise dispose of, or
          otherwise utilize the Collateral and any part or parts thereof in any
          manner authorized or permitted under the UCC after default by a
          debtor, and to apply the proceeds thereof toward payment of any costs
          and expenses and attorneys' fees and expenses thereby incurred by the
          Pledgee and toward payment of the Secured Obligations in such order or
          manner as permitted by law. Specifically and without limiting the
          foregoing, the Pledgee shall have the right to take possession of all
          or any part of the Collateral, any certificate therefor or any
          security therefor and of all books, records, papers and documents of
          the Pledgor or in the Pledgor's possession or control relating to the
          Collateral which are not already in the Pledgee's possession, and for
          such purpose may enter upon any premises upon which any of the
          Collateral or any security therefor or any of said books, records,
          papers and documents are situated and remove the same therefrom
          without any liability for trespass or damages thereby occasioned. To
          the extent permitted by law, the Pledgor expressly waives any notice
          of sale or other disposition of the Collateral and all other rights or
          remedies of the Pledgor or formalities prescribed by law relative to
          sale or disposition of the Collateral or exercise of any other right
          or remedy of the Pledgee existing after default hereunder. The Pledgee
          shall have all other rights and remedies available, whether at law or
          in equity.

                            B.   Upon notice by the Pledgee to the Pledgor, the
          Pledgee or its nominee or nominees shall have the sole and exclusive
          right to exercise all voting and consensual powers pertaining to the
          Collateral or any part thereof and may exercise such powers in such
          manner as the Pledgee may elect.

                            C.   All dividends, payments of interest and other
          distributions of every character made upon or in respect of the
          Pledged Shares or any part thereof shall be deemed to be Collateral
          and shall be paid directly to and shall be held by the Pledgee as
          additional Collateral pledged under and subject to this Agreement.

                                      168
<PAGE>

                    D.   All rights to marshaling of assets of the Pledgor,
          including any such right with respect to the Collateral, are hereby
          waived by the Pledgor.

                 VIII.  Special Provisions for Pledged Shares.
                        --------------------------------------

          The Pledgor hereby acknowledges that the sale by the Pledgee of any of
the Pledged Shares pursuant to the terms hereof in compliance with federal and
applicable state or securities laws or the securities laws of any other
applicable jurisdiction exercising valid jurisdiction over the Pledged Shares
(as now in effect or as hereafter amended, or any similar statute hereafter
adopted with similar purpose or effect, the "Securities Laws") may require
strict limitations as to the manner in which the Pledgee or any subsequent
transferee of the Pledged Shares may dispose of such securities.  The Pledgor
understands that in order to protect the Pledgee's interest it may be necessary
to sell the Pledged Shares at a price less than the maximum price attainable if
a sale were delayed or were made in another manner, such as a public offering
requested under the Securities Laws.  The Pledgor has no and waives any
objection to a sale in such a manner.

                 IX.  Application of Proceeds by the Pledgee.
                      ---------------------------------------

          In the event the Pledgee sells or otherwise disposes of the Collateral
in the course of exercising the remedies provided for in Sections 8 or 9 hereof,
                                                         ----------    -
any amounts held, realized or received by the Pledgee pursuant to the provisions
hereof, including the proceeds of the sale of any of the Collateral or any part
thereof, shall be applied by the Pledgee first toward the payment of any costs
and expenses incurred by the Pledgee in enforcing this Agreement, then to any
amounts otherwise due hereunder or under the Guaranty, and then as provided in
