all policies or certificates with respect thereto, the Assignee shall have the
right (but shall be under no obligation) to procure such insurance and the
Assignor 

                                       7

 
agrees to reimburse the Assignee for all costs and expenses of procuring such
insurance. The Assignee may apply any proceeds of such insurance when received
by it toward the payment of any of the Obligations to the extent the same shall
then be due. The Assignor assumes all liability and responsibility in connection
with the Collateral acquired by it and the liability of the Assignor to pay its
Obligations shall in no way be affected or diminished by reason of the fact that
such Collateral may be lost, destroyed, stolen, damaged or for any reason
whatsoever unavailable to the Assignor.

          6.2.  Warehouse Receipts Non-negotiable.  The Assignor agrees that if
                ---------------------------------                              
any warehouse receipt or receipt in the nature of a warehouse receipt is issued
with respect to any of its Inventory, such warehouse receipt or receipt in the
nature thereof shall not be "negotiable" (as such term is used in Section 7-104
of the Uniform Commercial Code as in effect in any relevant jurisdiction or
under other relevant law).

          6.3.  Further Actions.  The Assignor will, at its own expense, make,
                ---------------                                               
execute, endorse, acknowledge, file and/or deliver to the Assignee from time to
time such lists, descriptions and designations of its Collateral, warehouse
receipts, receipts in the nature of warehouse receipts, bills of lading,
documents of title, vouchers, invoices, schedules, confirmatory assignments,
conveyances, financing statements, transfer endorsements, powers of attorney,
certificates, reports and other assurances or instruments and take such further
steps relating to the Collateral and other property or rights covered by the
security interest hereby granted, which the Assignee deems reasonably
appropriate or advisable to perfect, preserve or protect its security interest
in the Collateral.

          6.4.  Financing Statements.  The Assignor agrees to assign and deliver
                --------------------                                            
to the Assignee such financing statements, in form acceptable to the Assignee,
as the Assignee may from time to time reasonably request or as are necessary or
desirable in the reasonable opinion of the Assignee to establish and maintain a
valid, enforceable, first priority security interest in the Collateral as
provided herein and the other rights and security contemplated herein, all in
accordance with the Uniform Commercial Code as enacted in any and all relevant
jurisdictions or any other relevant law.  The Assignor will pay any applicable
filing fees and related expenses.  The Assignor authorizes the Assignee to file
any such financing statements without the signature of the Assignor.

          SECTION 7.  REMEDIES UPON OCCURRENCE OF EVENT OF DEFAULT
                      --------------------------------------------

          7.1.  Remedies; Obtaining the Collateral Upon Default.  The Assignor
                -----------------------------------------------               
agrees that, if any Event of Default shall have occurred and be continuing, then
and in every such case, subject to any mandatory requirements of applicable law
then in effect, the Assignee, in addition to any rights now or hereafter
existing under applicable law, shall have all rights as a secured creditor under
the Uniform Commercial Code in all relevant jurisdictions and may:

          (a) personally, or by agents or attorneys, immediately retake
     possession of the Collateral or any part thereof, from the Assignor or any
     other Person who then has possession of any part thereof with or without
     notice or process of law, and for that purpose may enter upon the
     Assignor's premises where any of the Collateral is located 

                                       8

 
     and remove the same and use in connection with such removal any and all
     services, supplies, aids and other facilities of the Assignor; and

          (b) instruct the obligor or obligors on any agreement, instrument or
     other obligation (including, without limitation, the Receivables)
     constituting the Collateral to make any payment required by the terms of
     such instrument or agreement directly to the Assignee; and

          (c) withdraw all monies, securities and instruments in the Cash
     Collateral Account for application to the Obligations; and

          (d) sell, assign or otherwise liquidate, or direct the Assignor to
     sell, assign or otherwise liquidate, any or all of the Collateral or any
     part thereof, and take possession of the proceeds of any such sale or
     liquidation; and

          (e) take possession of the Collateral or any part thereof, by
     directing the Assignor in writing to deliver the same to the Assignee at
     any place or places designated by the Assignee, in which event the Assignor
     shall at its own expense:

               (i)    forthwith cause the same to be moved to the place or
          places so designated by the Assignee and there delivered to the
          Assignee,

               (ii)   store and keep any Collateral so delivered to the Assignee
          at such place or places pending further action by the Assignee as
          provided in Section 7.2, and

               (iii)  while the Collateral shall be so stored and kept, provide
          such guards and maintenance services as shall be necessary to protect
          the same and to preserve and maintain them in good condition;

it being understood that the Assignor's obligation so to deliver the Collateral
is of the essence of this Agreement and that, accordingly, upon application to a
court of equity having jurisdiction, the Assignee shall be entitled to a decree
requiring specific performance by the Assignor of such obligation.

          7.2.  Remedies; Disposition of the Collateral.  Any Collateral
                ---------------------------------------                 
repossessed by the Assignee under or pursuant to Section 7.1, and any other
Collateral whether or not so repossessed by the Assignee, may be sold, assigned,
leased or otherwise disposed of under one or more contracts or as an entirety,
and without the necessity of gathering at the place of sale the property to be
sold, and in general in such manner, at such time or times, at such place or
places and on such terms as the Assignee may, in compliance with any mandatory
requirements of applicable law, determine to be commercially reasonable.  Any of
the Collateral may be sold, leased or otherwise disposed of, in the condition in
which the same existed when taken by the Assignee or after any overhaul or
repair which the Assignee shall determine to be commercially reasonable.  Any
such disposition which shall be a private sale or other private proceeding
permitted by such requirements shall be made upon not less than 10 days' written
notice to the Assignor specifying the time at which such disposition is to be
made and the intended sale price 

                                       9

 
or other consideration therefor, and shall be subject, for the 10 days after the
giving of such notice, to the right of the Assignor or any nominee of the
Assignor to acquire the Collateral involved at a price or for such other
consideration at least equal to the intended sale price or other consideration
so specified. Any such disposition which shall be a public sale permitted by
such requirements shall be made upon not less than 10 days' written notice to
the Assignor specifying the time and place of such sale and, in the absence of
applicable requirements of law, shall be by public auction (which may, at the
Assignee's option, be subject to reserve), after publication of notice of such
auction not less than 10 days prior thereto in two newspapers in general
circulation in the city of Pleasanton. To the extent permitted by any such
requirement of law, the Assignee may bid for and become the purchaser of the
Collateral or any item thereof, offered for sale in accordance with this Section
7.2 without accountability to the Assignor (except to the extent of surplus
money received as provided in Section 7.4). If, under mandatory requirements of
applicable law, the Assignee shall be required to make disposition of the
Collateral within a period of time which does not permit the giving of notice to
the Assignor as hereinabove specified, the Assignee need give the Assignor only
such notice of disposition as shall be reasonably practicable in view of such
mandatory requirements of applicable law.

          7.3.  Waiver of Claims.  Except as otherwise provided in this
                ----------------                                       
Agreement, THE ASSIGNOR HEREBY WAIVES, TO THE EXTENT PERMITTED BY APPLICABLE
LAW, NOTICE AND JUDICIAL HEARING IN CONNECTION WITH THE ASSIGNEE'S TAKING
POSSESSION OR THE ASSIGNEE'S DISPOSITION OF ANY OF THE COLLATERAL, INCLUDING,
WITHOUT LIMITATION, ANY AND ALL PRIOR NOTICE AND HEARING FOR ANY PREJUDGMENT
REMEDY OR REMEDIES AND ANY SUCH RIGHT WHICH ASSIGNOR WOULD OTHERWISE HAVE UNDER
THE CONSTITUTION OR ANY STATUTE OF THE UNITED STATES OR OF ANY STATE, and the
Assignor hereby further waives, to the extent permitted by law:

          (i) all damages occasioned by such taking of possession except any
     damages which are the direct result of the Assignee's gross negligence or
     willful misconduct;

          (ii) all other requirements as to the time, place and terms of sale or
     other requirements with respect to the enforcement of the Assignee's rights
     hereunder; and

          (iii)  all rights of redemption, appraisement, valuation, stay,
     extension or moratorium now or hereafter in force under any applicable law
     in order to prevent or delay the enforcement of this Agreement or the
     absolute sale of the Collateral or any portion thereof, and the Assignor,
     for itself and all who may claim under it, insofar as it or they now or
     hereafter lawfully may, hereby waives the benefit of all such laws.

Any sale of, or the grant of options to purchase, or any other realization upon,
any Collateral shall operate to divest all right, title, interest, claim and
demand, either at law or in equity, of the Assignor therein and thereto, and
shall be a perpetual bar both at law and in equity against the Assignor and
against any and all Persons claiming or attempting to claim the Collateral so
sold, optioned or realized upon, or any part thereof, from, through and under
the Assignor.

          7.4.  Application of Proceeds.  The proceeds of any Collateral
                -----------------------                                 
obtained pursuant to Section 7.1 or disposed of pursuant to Section 7.2 shall be
applied as follows:

                                       10

 
          (i)   to the payment of any and all expenses and fees (including
     reasonable attorneys' fees) incurred by the Assignee in obtaining, taking
     possession of, removing, insuring, repairing, storing and disposing of
     Collateral and any and all amounts incurred by the Assignee in connection
     therewith;

          (ii)  next, any surplus then remaining to the payment of the
     Obligations in the following order of priority:

               (w) all interest accrued and unpaid;

               (x) the principal amount owing on the Loans;

               (y) the fees then owing to the Agent; and

               (z) all other Obligations then owing;

          (iii) if the Total Commitment is then terminated and no other
     Obligation is outstanding, any surplus then remaining shall be paid to the
     Assignor, subject, however, to the rights of the holder of any then
     existing Lien of which the Assignee has actual notice (without
     investigation);

it being understood that the Assignor shall remain liable to the extent of any
deficiency between the amount of the proceeds of the Collateral and the
aggregate amount of the sums referred to in clauses (i) and (ii) of this Section
7.4 with respect to the Assignor.

          7.5.  Remedies Cumulative.  No failure or delay on the part of the
                -------------------                                         
Assignee in exercising any right, power or privilege hereunder or under any
other Credit Document and no course of dealing between the Assignor and the
Assignee shall operate as a waiver thereof; nor shall any single or partial
exercise of any right, power or privilege hereunder or under any other Credit
Document preclude any other or further exercise thereof or the exercise of any
other right, power or privilege hereunder or thereunder.  The rights, powers and
remedies herein or in any other Credit Document expressly provided are
cumulative and not exclusive of any rights, powers or remedies which the
Assignee would otherwise have.  No notice to or demand on the Assignor in any
case shall entitle the Assignor to any other or further notice or demand in
similar or other circumstances or constitute a waiver of the rights of the
Assignee to any other or further action in any circumstances without notice or
demand.

          7.6.  Discontinuance of Proceedings.  In case the Assignee shall have
                -----------------------------                                  
instituted any proceeding to enforce any right, power or remedy under this
Agreement by foreclosure, sale, entry or otherwise, and such proceeding shall
have been discontinued or abandoned for any reason or shall have been determined
adversely to the Assignee, then and in every such case the Assignor and the
Assignee shall be restored to their former positions and rights hereunder with
respect to the Collateral subject to the security interest created under this
Agreement, and all rights, remedies and powers of the Assignee shall continue as
if no such proceeding had been instituted.

                      ---------

agents (hereinafter in this Section 8.1 referred to individually as "Indemnitee"
and collectively as "Indemnitees") harmless from any and all liabilities,

costs, expenses or disbursements (including reasonable attorneys' fees and
expenses) (for the purposes of this Section 8.1 the foregoing are collectively
called "expenses") of whatsoever kind or nature which may be imposed on,
asserted against or incurred by any of the Indemnitees in any way relating to or
arising out of this Agreement, any other Credit Document or the documents
executed in connection herewith and therewith or in any other way connected with
the administration of the transactions contemplated hereby and thereby or the

thereof, or in any way relating to or arising out of the manufacture, ownership,

operation, condition, sale, return or other disposition or use of the Collateral
(including, without limitation, latent or other defects, whether or not

governmental body or unit, any tort (including, without limitation, claims
arising or imposed under the doctrine of strict liability, or for or on account

property damage) or any contract claim; provided that no Indemnitee shall be
indemnified pursuant to this Section 8.1(a) for expenses to the extent caused by
the gross negligence or willful misconduct of such Indemnitee.  The Assignor
agrees that upon written notice by any Indemnitee of any assertion that could
give rise to an expense, the Assignor shall assume full responsibility for the
defense thereof.  Each Indemnitee agrees to use its best efforts to promptly
notify the Assignor of any such assertion of which such Indemnitee has
knowledge.

          (b) Without limiting the application of Section 8.1(a), the Assignor
agrees to pay, or reimburse the Assignee for (if the Assignee shall have
incurred fees, costs or expenses because the Assignor shall have failed to
comply with its obligations under this Agreement or any other Credit Document),
any and all fees, costs and expenses of whatever kind or nature incurred in
connection with the creation, preservation or protection of the Assignee's Liens
on, and security interest in, the Collateral, including, without limitation, all
fees and taxes in connection with the recording or filing of instruments and
documents in public offices, payment or discharge of any taxes or Liens upon or
in respect of the Collateral, premiums for insurance with respect to the
Collateral and all other fees, costs and expenses in connection with protecting,
maintaining or preserving the Collateral and the Assignee's interest therein,
whether through judicial proceedings or otherwise, or in defending or
prosecuting any actions, suits or proceedings arising out of or relating to the
Collateral.

          (c) Without limiting the application of Section 8.1(a) or (b), the
Assignor agrees to pay, indemnify and hold each Indemnitee harmless from and
against any expenses which such Indemnitee may suffer, expend or incur in
consequence of or growing out of any misrepresentation by the Assignor in this
Agreement or any of the other Credit Documents or in any statement or writing
contemplated by or made or delivered pursuant to or in connection with this
Agreement or any of the other Credit Documents.

                                       12

 
          (d) If and to the extent that the obligations of the Assignor under
this Section 8.1 are unenforceable for any reason, Assignor hereby agrees to
make the maximum contribution to the payment and satisfaction of such
obligations which is permissible under applicable law.

          8.2.  Indemnity Obligations Secured by Collateral; Survival.  Any
                -----------------------------------------------------      
amounts paid by any Indemnitee as to which such Indemnitee has the right to
reimbursement shall constitute Obligations secured by the Collateral.  The
indemnity obligations of the Assignor contained in this Article VIII shall
continue in full force and effect notwithstanding the full payment of all the
Notes issued under the Credit Agreement and all of the other Obligations and
notwithstanding the discharge thereof.
