                                    Remedies

         Section 6.01. Remedies. If an Event of Default shall occur and be
continuing, the Lender shall have each and every right and remedy available to
it whether at law, in equity or otherwise, including, without limitation, each
of the following:

                  (a) UCC Remedies. The Lender may exercise all rights and
         remedies in respect of the Collateral available to a secured party
         under the Uniform Commercial Code in effect in the relevant
         jurisdiction (whether or not the Uniform Commercial Code applies to the
         affected Collateral), by law or otherwise.

                  (b) Exercise Rights of Borrower. The Lender may exercise any
         and all rights and remedies of the Borrower under or in respect of the
         Collateral, including, without limitation, any and all rights of the
         Borrower to demand or otherwise require payment of

                                       20

<PAGE>

         any amount under, or performance of any provision of, the Collateral,
         or the right of the Borrower to vote or consent with respect to any
         Collateral.

                  (c) Take Possession of Collateral. The Lender may take
         possession of the Collateral and, without liability for trespass, enter
         on any premises for the purpose of taking possession of or removing any
         Collateral.

                  (d) Right to Sell Collateral.

                  (i) The Lender may, without demand of performance or other
         demand, presentment, protest, advertisement or notice of any kind, and
         without notice to the Borrower except as specified in this Section
         6.01, sell, lease, assign, give option or options to purchase, or
         otherwise, dispose of and deliver all or any part of the Collateral in
         one or more parcels at public or private sale, at any of the Lender's
         offices, on any securities exchange, or elsewhere, for cash, on credit
         or for future delivery, and upon such other terms as the Agent may deem
         commercially reasonable.

                  (ii) The Borrower agrees that, to the extent notice of sale
         shall be required by law, at least ten days notice to the Borrower of
         the time and place of any public sale or the time after which any
         private sale is to be made shall constitute reasonable notification.
         The Lender shall not be obligated to consummate any sale of Collateral
         regardless of notice of sale having been given. The Lender may adjourn
         any public sale from time to time by any notice or announcement and may
         make any sale without further notice of the time and place to which the
         sale was so adjourned.

                  (iii) For purposes of this Agreement, a written agreement to
         purchase all or any of the Collateral shall be deemed to be a sale of
         that property and the Lender shall be free to carry out the agreement
         notwithstanding that the Event of Default shall have been cured and the
         Obligations paid in full.

                  (iv) If all or any part of the Collateral is sold on credit or
         for future delivery, the property may be retained by the Lender until
         the sale price is paid by the purchaser or purchasers, but the Lender
         shall not be liable if the purchaser or purchasers fail to take up and
         pay for the property and, in that event, the Lender may again sell the
         property pursuant to this Section.

                  (v) The Lender may restrict the bidders or purchasers to
         persons (A) representing that they are purchasing the Collateral for
         their own account for investment and not with a view to further
         distribution or sale and (B) satisfying the offeree and purchaser
         requirements for a valid private placement or limited offering under
         the Securities Act of 1933, as amended. The Borrower understands and
         agrees that the sale may be made at prices and on terms less favorable
         than a public sale and agrees that any such sale shall be

                                       21

<PAGE>

         deemed to have been made in a commercially reasonable manner even if
         the Lender accepts the first offer received.

                  (vi) To the extent permitted by law, the Lender may purchase
         all or any part of the Collateral at any public or private sale or
         sales free of any equity or right of redemption, stay, valuation or
         appraisal on the part of the Borrower (all said rights being hereby
         waived and released to the extent permitted by law) and may make
         payment for the purchase by using any claim then due and payable to the
         Lender from the Borrower as a credit against the purchase price, and
         the Lender may, upon compliance with the terms of sale, hold, retain
         and transfer the property without further accountability to the
         Borrower.

                  (vii) Each purchaser at any such sale shall hold the property
         sold absolutely free from any claim or right on the part of the
         Borrower, and the Borrower hereby waives (to the extent permitted by
         law) all rights of redemption, stay, valuation and appraisal which the
         Borrower now has or may at any time in the future have under rule of
         law or statute now existing or hereafter enacted.

                  (e) Store Collateral. The Lender may cause any Collateral to
         be held, stored, processed or completed prior to sale, and expenses
         incurred for this purpose shall constitute Obligations hereunder. The
         Borrower agrees to assemble the Collateral and make it available to the
         Lender at places where the Lender may reasonably select, whether at the
         Borrower's premises or elsewhere.

                  (f) Notices to Account Debtors, Obligors, Etc. The Lender may,
         without notice to the Borrower, (i) notify the account debtors,
         obligors or bailees under or of any of the Collateral of the assignment
         and pledge to the Lender of the Collateral, (ii) direct the account
         debtors or obligors to make payment and direct the bailees to make
         delivery directly to the Lender shall otherwise direct, of all amounts
         due or to become due to the Borrower under the Collateral and (iii)
         collect, adjust, settle or compromise those obligations. While the
         Lender is exercising any authority under this Section the Borrower
         shall not adjust, settle or compromise any obligation under the
         Collateral, release wholly or partly any account debtor or obligor in
         respect of those obligations, or allow any credit or discount on those
         obligations.

                  (g) All Other Remedies. The Lender may exercise all other
         rights and/or remedies available, whether at law, in equity or
         otherwise.

         Section 6.02. Waiver. To the extent permitted by applicable law, the
Borrower waives all claims, damages and demands it may acquire against the
Lender arising out of the exercise by the Lender of any of its rights under this
Agreement.

         Section 6.03. Remedies Cumulative. All rights and remedies of the
Lender existing under this Agreement and any other Loan Document are cumulative

and other items received by the Borrower under or in respect of any Collateral

Collateral in accordance with the Loan Agreement.

         (b) Borrower Remains Liable. The Borrower shall remain fully liable for
any deficiency if the proceeds or other realization of the Collateral are
insufficient to pay the Obligations and the fees and disbursements of any
attorneys employed by the Lender to collect such deficiency.

         (c) Collateral In Excess of Obligations. Any amount held by the Lender
under this Agreement after all the Obligations have been indefeasibly and
finally paid in full in cash shall be paid over to the Borrower or to any other
Person lawfully entitled to receive payment.

equities and rights of appraisal, stay and redemption (whether now or hereafter
existing), in each case arising out of the Lender enforcing any of its rights

or release of a party granting security or which might otherwise limit recourse
against the Borrower.

         otherwise, of the Borrower, the Guarantor or any other person from any
         Obligation or any provision of any Loan Document or other document; and

                  (xii) any other circumstance whatsoever, foreseen or
         unforeseen, which may or might in any manner or to any extent vary the
         risks of the Guarantor or might otherwise constitute a defense
         available to or a legal or equitable discharge of a surety or a
         guarantor or limit recourse against the Guarantor or otherwise.

                  requests of the Lender under Section 5.01(i) of the Loan
                  Agreement relating to Guarantor, this Agreement, the Pledge
                  Agreement or the Pledged Collateral.

         Section 3.02. Negative Covenants. Until the Obligations shall be paid
and otherwise performed in full, the Guarantor shall not, and shall not permit
the Borrower to, do the following:

                  (a) Mergers, Etc. Merge or consolidate with, or sell, assign,
         lease or otherwise dispose of (whether in one transaction or in a
         series of transactions) all or substantially all of its assets (whether
         now owned or hereafter acquired) to, any Person, or acquire all or
         substantially all of the assets or the business of any Person.

                  (b) Transactions with Affiliates. Enter into any transaction
         (including, but not limited to, the purchase, sale or exchange of
         property or the rendering of any service) with any Affiliate except in
         the ordinary course of its business, pursuant to the reasonable
         requirements of its business and upon fair and reasonable terms no less
         favorable to it than would obtain in a comparable arm's length
         transaction with a person not an Affiliate.

                  (c) Accounting Changes. Make or permit any significant change
         in accounting policies or reporting practices, except for any change
         required by GAAP.

                  (d) Stock of Subsidiary. Transfer of any of the equity
         interest of any Subsidiary (including the Borrower (except with respect
         to the possible transaction with SoftNet pursuant to the term sheet
         attached hereto as Exhibit A)). Issue any additional equity interests
         in the Borrower.

                      Termination, Waivers and Subrogation

         Section 4.01. Continuing Guaranty. This Agreement shall continue to be
effective and shall remain in full force and effect until the Obligations shall
be paid and otherwise performed in full. For the purposes of this Agreement, the
Obligations shall not be deemed to have been paid and performed in full until
the holders or owners of the Obligations shall have indefeasibly received
payment of the Obligations in full in cash. Thereafter, this Agreement shall be
reinstated if at any time any payment of any of the Obligations is rescinded or
must otherwise be returned upon the insolvency, bankruptcy or reorganization of
the Borrower or any other person or otherwise, all as though the payment had not
been made.

         Section 4.02. Waivers by the Guarantor. The Guarantor unconditionally
waives, to the full extent permitted by law:

                  (a) any defense, set-off or counterclaim which the Guarantor
         may otherwise assert against the Borrower or the Lender;

                  (b) presentment, protest, demand for payment, promptness,
         diligence, notice of protest, notice of any other action at any time
         taken or omitted by the Lender and, generally, all demands and notices
         of every kind in connection with any Loan Document or the Obligations,
         including, but not limited to:

                           (i) notice of any of the matters referred to in
                  Section 1.01(e);

                           (ii) all notices which may be required by statute,
                  rule of law or otherwise, now or hereafter in effect, to
                  preserve intact any rights against the Guarantor under any
                  Loan Document or as a requirement to the enforcement,
                  assertion or exercise against the Borrower or the Guarantor of
                  any right, power, privilege or remedy conferred under any Loan
                  Document;

                  (c) any requirement to exhaust any rights or remedies or to
         mitigate the damages resulting from any default under any Loan Document
         or any other document or any requirement to protect, secure, perfect or
         insure any Lien or any property subject to the Lien or take any other
         action against any person or any collateral or other property;

                  (d) all claims that the sale price of any collateral was
         inadequate or unreasonable for any reason and all other claims to
         damages and demands of any nature against the Lenders;

                                       -7-

<PAGE>

                  (e) all equities and rights of appraisal, stay and redemption
         (whether now or hereafter existing), in each case arising out of the
         Lender enforcing any of its rights and remedies under any Loan
         Document;

                  (f) any exoneration or release from the Obligations resulting
         from any loss by the Guarantor of its rights, if any', of subrogation
         or contribution; and

                  (g) any other circumstance whatsoever, including, but not
         limited to, those stated in Section 1.01(d), which might otherwise
         constitute a defense to or a legal or equitable discharge or release of
         a guarantor or surety or a party granting security or which might
         otherwise limit recourse against the Guarantor.

         Section 4.03. Subrogation; Subordination.

         (a) The Guarantor shall not be subrogated, in whole or in part, to the
rights of the Lender against the Borrower under any Loan Document until the
payment in full of the Obligations.

         (b) Any claim of the Guarantor against the Borrower arising from
payments made by the Guarantor under this Agreement shall be in all respects
subordinate to the payment and performance in full and discharge of the
Obligations.

         (c) No payment under this Agreement by the Guarantor shall give rise to
any claim of the Guarantor against the Lender or any other holder of the
Obligations.

         (d) Unless and until all Obligations shall have been paid and performed
in full, the Guarantor will not assign or otherwise transfer any claim against
the Borrower to any other person.

         (e) The Guarantor agrees that any rights it may have against any other
guarantor of any of the Obligations for contributions, exoneration from payment
or otherwise, in respect of any amounts paid by the Guarantor under this
Agreement or which may continue to be owing under this Agreement, shall be
postponed until, and the Guarantor agrees not to seek to enforce any such right
until, the Obligations are paid and performed in full.

         Section 4.04. Effect of Bankruptcy Proceedings. If an event permitting
the acceleration of any of the Obligations shall at any time have occurred and
be continuing, and the acceleration shall at such time be prevented by reason of
the pendency against the Borrower of a case or proceeding under a bankruptcy or
insolvency law, the Guarantor agrees that, for purposes of this Agreement and
the Guarantor's obligations under this Agreement, the Obligations shall be
deemed to have been accelerated with the same effect as if they had been
accelerated in accordance with the terms of the Loan Documents. In this event
the Guarantor shall immediately pay the full amount of the Obligations due and
owing by reason of the acceleration, without further notice or demand.
