Secured Party at any time during normal business hours to examine and inspect
the Collateral and to make abstracts from such records and chattel paper, and
(b) furnish to Secured Party such information and reports regarding the

all of the Pledged Securities to be transferred of record into the name of
Secured Party (or a designee of Secured Party).

    Section 9.  Right to Receive Distributions on Pledged Securities.  Unless an
    ---------   ----------------------------------------------------
Event of Default shall have occurred and be continuing, Debtor shall be
entitled, from time to time, to collect and receive for its own use all
dividends, interest and other payments and distributions made upon or with
respect to the Pledged Securities, except:

     (i)   dividends of stock;

     (ii)  dividends payable in securities or other property (except cash
     dividends);

     (iii) other securities issued with respect to or in lieu of the Pledged
     Securities (whether upon conversion of the convertible securities included
     therein or through stock split, spin-off, split-off, reclassification,
     merger, consolidation, sale of assets, combination of shares or otherwise).

All of the foregoing, together with all new, substituted or additional shares of
capital stock, warrants, options or other rights, or other securities issued in
addition to or in respect of all or any of the Pledged Securities shall be
delivered to Secured Party hereunder as required by Section 3 hereof, to be held
                                                    ---------
as Collateral pursuant to the terms hereof in the same manner as the Pledged
Securities delivered to Secured Party on the date hereof.

    Section 10. Right to Vote Pledged Securities.  Unless an Event of Default
    ----------  --------------------------------
shall have occurred and be continuing, Debtor shall have the right, from time to
time, to vote and to give consents, ratifications and waivers with respect to

a written request from Debtor accompanied by a certificate signed by

                                       4


Debtor's principal financial officer stating that no Event of Default has
occurred and is continuing, deliver to Debtor or as specified in such request
such proxies, powers of attorney, consents, ratifications and waivers in respect
of any Pledged Securities which are registered in Secured Party's name, and make
such arrangements with respect to the conversion of convertible securities as
shall be specified in Debtor's request, such arrangements to be in form and
substance reasonably satisfactory to Secured Party.

    If an Event of Default shall have occurred and be continuing, and provided
Secured Party elects to exercise the rights hereinafter set forth by notice to
Debtor of such election, Secured Party shall have the right, to the extent
permitted by law, and Debtor shall take all such action as may be necessary or
reasonably appropriate to give effect to such right, to vote and to give
consents, ratifications and waivers and take any other action with respect to
all the Pledged Securities with the same force and effect as if Secured Party

    Section 11.  General Authority.  Debtor hereby irrevocably appoints Secured
    ----------   -----------------
Party Debtor's lawful attorney, with full power of substitution, in the name of
Debtor, for the sole use and benefit of Secured Party, its successors and
assigns, but at Debtor's expense, to exercise, all or any of the following
powers with respect to all or any of the Collateral during the existence and

         (iv)  to sell, transfer, assign or otherwise deal in or with the same
    or the proceeds or avails thereof or the related goods securing the Customer
    Receivables, as fully and effectually as if Secured Party were the absolute
    owner thereof;

         (v)   to extend the time of payment of any or all thereof and to make
    any allowance and other adjustments with reference thereto;

         (vi)  to discharge any taxes or Liens at any time placed thereon; and

         (vii) to execute any document or form, in the name of Debtor, which

    Securities by Secured Party, including without limitation Form 144
    promulgated by the Securities and Exchange Commission;

                                       5


provided, that Secured Party shall give Debtor not less than ten (10) days'
prior written notice of the time and place of any sale or other intended
disposition of any of the Collateral.

    Section 12.  Events of Default.  Debtor shall be in default under this
    ----------   -----------------
Security Agreement upon the occurrence and continuance of any Event of Default
under the Loan Agreement.

    Section 13.  Remedies Upon Event of Default.  If any Event of Default shall
    ----------   ------------------------------
have occurred and be continuing, Secured Party may exercise all the rights and
remedies of a secured party under the Uniform Commercial Code. Secured Party may
require Debtor to assemble all or any part of the Collateral and make it
available to Secured Party at a place to be designated by Secured Party which is
reasonably convenient. Secured Party shall give Debtor ten (10) days' written
notice of its intention to make any public or private sale or sale at a broker's
board or on a securities exchange of the Collateral. At any such sale the
Collateral may be sold in one lot as an entirety or in separate parcels, as
Secured Party may determine. Secured Party shall not be obligated to make any
such sale pursuant to any such notice. To the extent permitted by law, Secured
Party may, without notice or publication, adjourn any public or private 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 adjourned. Secured Party, instead of exercising the power
of sale herein conferred upon it, may proceed by a suit or suits at law or in
equity to foreclose the Security Interests and sell the Collateral, or any
portion thereof, under a judgment or decree of a court or courts of competent
jurisdiction.

    Section 14.  Application of Collateral and Proceeds.  The proceeds of any
    ----------   --------------------------------------
sale of, or other realization upon, all or any part of the Collateral shall be
applied in the following order of priorities:  (a) first, to pay the expenses of
such sale or other realization, including reasonable attorneys' fees, and all
expenses, liabilities and advances incurred or made by Secured Party in
connection therewith, and any other unreimbursed expenses for which Secured
Party may be reimbursed pursuant to Section 15; (b) second, to the payment of
                                    ----------
the Obligations in such order of priority as Secured Party, in its sole
discretion, shall determine; and (c) finally, to pay to Debtor, or its
successors or assigns, or as a court of competent jurisdiction may direct, any
surplus then remaining from such proceeds.

    Section 15.  Expenses; Secured Party's Lien.  Debtor will within 30 days
    ----------   ------------------------------
after the presentation of invoices pay to Secured Party: (a) the amount of any
taxes which Secured Party may have been required to pay by reason of the
Security Interests (including any applicable transfer and personal property
taxes but excluding taxes in respect of Secured Party's income and profits) or
to free any of the Collateral from any Lien thereon (except for any Lien
permitted under the Loan Agreement) and (b) the amount of any and all reasonable
costs and expenses, including the reasonable fees and disbursements of its
counsel and of any agents not regularly in its employ, which Secured Party may
incur in connection with (i) the collection or other disposition of any of the
Collateral, (ii) the exercise by Secured Party of any of the powers conferred
upon it hereunder, (iii) any default on Debtor's part hereunder or (iv) any
Bankruptcy Event.

                                       6


    Section 16.  Termination of Security Interests; Release of Collateral.  Upon
    ----------   --------------------------------------------------------
the repayment and performance in full of all the Obligations and the expiration
or termination of any obligations of Secured Party to advance funds to Debtor,
or upon the sale of any Collateral which is permitted under the Loan Agreement
or as otherwise consented to in writing by Secured Party, the Security Interests
on such sold Collateral shall terminate and all rights to the Collateral shall
revert to Debtor.  Upon any such termination of the Security Interests or
release of Collateral, Secured Party will execute and deliver to Debtor such
documents as Debtor shall reasonably request to evidence the termination of the
Security Interests or the release of such Collateral, as the case may be.
Notwithstanding the foregoing, this Security Agreement shall be reinstated if at
any time any payment made or value received with respect to an Obligation is
rescinded, invalidated, declared to be fraudulent or preferential, or set aside
or is required to be repaid to a trustee, receiver or any other party under any
case or proceeding, voluntary or involuntary, for the distribution, division or
application of all or part of the assets of Debtor or the proceeds thereof,
whether such case or proceeding be for the liquidation, dissolution or winding
up of Debtor or their respective businesses, a receivership, insolvency or
bankruptcy case or proceeding, an assignment for the benefit of creditors or a
proceeding by or against Debtor for relief under the federal Bankruptcy Code or
any other bankruptcy, reorganization or insolvency law or any other law relating
to the relief of debtors, readjustment of indebtedness, reorganization,
arrangement, composition or extension or marshalling of assets or otherwise, all
as though such payment had not been made or value received.

    Section 17.  Notices.  All notices, requests, demands and other
    ----------   -------
communications provided for hereunder shall be in writing and mailed or
telefaxed or delivered to the applicable party in the manner set forth in
Section 9.6 of the Loan Agreement.
- -----------

    Section 18.  Additional Provision Regarding Pledged Securities.  With
    ----------   -------------------------------------------------
respect to any Pledged Securities which are delivered to the Secured Party
pursuant to a separate pledge agreement, to the extent any provisions of that
pledge agreement are inconsistent with the terms of this Security Agreement, the
terms of that separate pledge agreement will govern.

    Section 19.  Miscellaneous.  (a) No failure on the part of Secured Party to
    ----------   -------------
exercise, and no delay in exercising, and no course of dealing with respect to,
any right, power or remedy under this Security Agreement shall operate as a
waiver thereof; nor shall any single or partial exercise by Secured Party of any
right, power or remedy under this Security Agreement preclude any other right,
power or remedy.  The remedies in this Security Agreement are cumulative and are
not exclusive of any other remedies provided by law.  Neither this Security
Agreement nor any provision hereof may be changed, waived, discharged or
terminated orally but only by a statement in writing signed by the party against
which enforcement of the change, waiver, discharge or termination is sought;

    (b) This Security Agreement shall be construed in accordance with and
governed by the laws of The Commonwealth of Massachusetts, except as otherwise
required by mandatory provisions of law and except to the extent that remedies
provided by the laws of any state other than The Commonwealth of Massachusetts
with respect to Collateral located in any such other state are governed by the
laws of said state; and.

                                       7


    (c) This Security Agreement may be executed in several counterparts, each of
which shall be an original and all of which shall constitute but one and the
same Security Agreement.

    Section 20.  Consent to Jurisdiction and Service of Process.
    ----------   ----------------------------------------------

    (a)  Except to the extent prohibited by applicable law, Debtor irrevocably:

     (i)  agrees that any suit, action, or other legal proceeding arising out of
     this Security Agreement or any of the Loans may be brought in the courts of
     record of The Commonwealth of Massachusetts or any other state(s) in which
     any of the Collateral is located or the courts of the United States located
     in The Commonwealth of Massachusetts or any other state(s) in which any of
     the Collateral is located;

     (ii)  consents to the jurisdiction of each such court in any such suit,
     action or proceeding; and

     (iii)  waives any objection which it may have to the laying of venue of
     such suit, action or proceeding in any of such courts.

    For such time as any of the Obligations of Debtor to Secured Party shall be
unpaid in whole or in part and/or the Commitment is in effect, Debtor
irrevocably designates the registered agent or agent for service of process of
the Debtor as reflected on the records of the Secretary of State of California
as its registered agent, and, in the absence thereof, the Secretary of State of
State of California, as its agent to accept and acknowledge on its behalf
service of any and all process in any such suit, action or proceeding brought in
any such court and agrees and consents that any such service of process upon
such agent and written notice of such service to Debtor by registered or
certified mail shall be taken and held to be valid personal service upon Debtor
regardless of where Debtor shall then be doing business and that any such
service of process shall be of the same force and validity as if service were
made upon it according to the laws governing the validity and requirements of
such service in each such state and waives any claim of lack of personal service
or other error by reason of any such service.  Any notice, process, pleadings or
other papers served upon the aforesaid designated agent shall, within three (3)
Business Days after such service, be sent by the method provided therefor under
Section 9.6 of the Loan Agreement to the Debtor at its address set forth in the
- -----------
Loan Agreement. EACH OF THE PARTIES HERETO HEREBY WAIVES ANY RIGHT TO TRIAL BY
JURY IN THE EVENT OF ANY DISPUTE BETWEEN THE DEBTOR AND SECURED PARTY WITH
RESPECT TO THE FINANCING DOCUMENTS AND/OR ANY OF THE TRANSACTIONS CONTEMPLATED
THEREBY.

    Section 21.  Severability.  If any provision hereof is invalid or
    ----------   ------------
unenforceable in any jurisdiction, the other provisions hereof shall remain in
full force and effect in such jurisdiction and shall be liberally construed in
favor of Secured Party.

    IN WITNESS WHEREOF, this Security Agreement has been executed by the parties
hereto all as of the day and year first above written.
