                                  ARTICLE III
                    SPECIAL PROVISIONS CONCERNING TRADEMARKS

         3.1      Additional Representations and Warranties. Assignor represents
                  -----------------------------------------
and warrants that it is the true and lawful owner of or otherwise has the right
to use (as such may be limited by law) the registered Marks listed in Annex B
hereto for Assignor and that said listed Marks include all United States and
foreign marks registered in and applications for marks filed with the United
States Patent and Trademark Office or any foreign equivalent that Assignor owns
or uses in connection with its business as of the date hereof. Assignor
represents and warrants that it owns, is licensed to use or otherwise has the
right to use, all Marks that it uses. Assignor further warrants that it has no
knowledge of any third party claim received by it that any aspect of Assignor's
present or contemplated business operations infringes or will infringe any
trademark, service mark or trade name of any other Person other than as could
not, either individually or in the aggregate, reasonably be expected to have a
Material Adverse Effect. Assignor represents and warrants that it is the true
and lawful owner of or otherwise has the right to use all U.S. trademark
registrations and applications and all foreign trademark registrations and
applications, in each case, listed in Annex B hereto and that said registrations
are valid, subsisting, have not been canceled and that Assignor is not aware of
any third-party claim that any of said registrations is invalid or
unenforceable, is not aware that there is any reason that any of said
registrations is invalid or unenforceable, and is not aware that there is any
reason that any of said applications will not pass to registration. Assignor
hereby grants to the Secured Party an absolute power of attorney to sign, upon
the occurrence and during the continuance of an Event of Default, any document
which may be required by the United States Patent and Trademark Office or
foreign equivalent office in order to effect an absolute assignment of all
right, title and interest in each Mark, and record the same.

         3.2      Licenses and Assignments. Except as otherwise permitted
                  ------------------------
hereby, Assignor hereby agrees not to divest itself of any right under any Mark
absent prior written approval of the Secured Party.

         3.3      Infringements. Assignor agrees, promptly upon learning
                  -------------
thereof, to notify the Secured Party in writing of the name and address of, and
to furnish such pertinent information that may be available with respect to, any
party who Assignor believes is infringing or diluting or

                                       4

<PAGE>

otherwise violating any of Assignor's rights in and to any Mark in any manner
that could reasonably be expected to have a Material Adverse Effect, or with
respect to any party claiming that Assignor's use of any Mark violates any
property right of that party other than as could not reasonably be expected to
have a Material Adverse Effect. Assignor further agrees to prosecute in
accordance with reasonable business practices any Person infringing any Mark in
any manner that could reasonably be expected to have a Material Adverse Effect.

         3.4      Preservation of Marks. Assignor agrees to use its Marks in
                  ---------------------
interstate commerce during the time in which this Agreement is in effect and to
take all such other actions as are reasonably necessary to preserve such Marks
as trademarks or service marks under the laws of the United States or foreign
jurisdictions (other than any such Marks determined by Assignor, in the exercise
of its reasonable business judgment, to be no longer useful or advantageous to
the ongoing conduct of its business).

         3.5      Maintenance of Registration. Assignor shall, at its own
                  ---------------------------
expense, in a commercially reasonable manner process such documents as are
reasonably required to maintain trademark registrations, including but not
limited to affidavits of use and applications for renewals of registration in
the United States Patent and Trademark Office or foreign equivalent office for
all of its material registered Marks, and shall pay all fees and disbursements
in connection therewith and shall not abandon any such filing of affidavit of
use or any such application of renewal prior to the exhaustion of all
administrative and judicial remedies without prior written consent of the
Secured Party (other than with respect to registrations and applications
determined by Assignor, in the exercise of its reasonable business judgment, to
be no longer materially useful or advantageous to the ongoing conduct of its
business).

         3.6      Future Registered Marks. If any Mark registration is issued
                  -----------------------
hereafter to Assignor as a result of any application now or hereafter pending
before the United States Patent and Trademark Office or foreign equivalent
office, within 30 days of receipt of such certificate, Assignor shall deliver to
the Secured Party a copy of such certificate, and an assignment for security in
such Mark, to the Secured Party and at the expense of Assignor, confirming the
assignment for security in such Mark to the Secured Party hereunder, the form of
such security to be substantially in the form of Annex E hereto or in such other
form as may be reasonably satisfactory to the Secured Party.

         3.7      Remedies. If an Event of Default shall occur and be
                  --------
continuing, the Secured Party may, by written notice to Assignor, take any or
all of the following actions: (i) declare the entire right, title and interest
of Assignor in and to each of the Marks, together with all trademark rights and
rights of protection to the same, vested in the Secured Party in which event
such rights, title and interest shall immediately vest, and the Secured Party
shall be entitled to exercise the power of attorney referred to in Section 3.1
hereof to execute, cause to be acknowledged and notarized and record said
absolute assignment with the applicable agency; (ii) take and use or sell the
Marks and the goodwill of Assignor's business symbolized by the Marks and the
right to carry on the business and use the assets of Assignor in connection with
which the Marks have been used; and (iii) direct Assignor to refrain, in which
event Assignor shall refrain, from using the Marks in any manner whatsoever,
directly or indirectly, and Assignor shall execute such further documents that
the Secured Party may reasonably request to further confirm this and to

                                       5

<PAGE>

transfer ownership of the Marks and registrations and any pending trademark
application in the United States Patent and Trademark Office or foreign
equivalent office to the Secured Party.

                                   ARTICLE IV
                          SPECIAL PROVISIONS CONCERNING
                      PATENTS, COPYRIGHTS AND TRADE SECRETS

         4.1      Additional Representations and Warranties. Assignor represents
                  -----------------------------------------
and warrants that it is the true and lawful owner or licensee of all rights in
(i) all United States trade secrets and proprietary information necessary to
operate the business of the Assignor (the "Trade Secret Rights"), (ii) the
Patents listed in Annex C hereto for Assignor and that said Patents include all
the United States and foreign patents and applications for United States and
foreign patents that Assignor owns as of the date hereof and (iii) the
Copyrights listed in Annex D hereto for Assignor and that said Copyrights
constitute all the United States and foreign copyrights and applications to
United States and foreign copyrights that Assignor owns as of the date hereof.
Assignor further warrants that it has no knowledge of any third party claim that
any aspect of Assignor's present or contemplated business operations infringes
or will infringe any patent of any other Person or Assignor has misappropriated
any trade secret or proprietary information which, either individually or in the
aggregate, could reasonably be expected to have a Material Adverse Effect.
Assignor hereby grants to the Secured Party an absolute power of attorney to
sign, upon the occurrence and during the continuance of any Event of Default,

                  ---------------------
it does not as of the date hereof own any Copyrights that are registered with
the United States Copyright Office or foreign equivalent office. Assignor
covenants that should it at any time intend to apply for registration for any of
its Copyrights with the United States Copyright Office or foreign equivalent
office, or should it apply for a Patent with the United States Patent and
Trademark Office or foreign equivalent office, it will give Secured Party
written notice of such intent to apply for a Copyright registration or Patent
with such office 30 days prior to the making of such application.

         4.3      Licenses and Assignments. Except as otherwise permitted
                  ------------------------
hereby, Assignor hereby agrees not to divest itself of any right under any
Patent or Copyright acquired after the date hereof absent prior written approval
of the Secured Party, which shall not be unreasonably withheld.

         4.4      Infringements. Assignor agrees, promptly upon learning
                  -------------
thereof, to furnish the Secured Party in writing with all pertinent information
available to Assignor with respect to any infringement, contributing
infringement or active inducement to infringe of any Patent or Copyright or to
any claim that the practice of any Patent or use of any Copyright violates any
property right of a third party in each case, in any manner which, either
individually or in the aggregate, could reasonably be expected to have a
Material Adverse Effect, or that with respect to any misappropriation of any
Trade Secret Right or any claim that practice of any Trade Secret Right violates
any property right of a third party, in each case, in any manner which, either

                                       6

<PAGE>

individually or in the aggregate, could reasonably be expected to have a
Material Adverse Effect. Assignor further agrees, absent direction of the
Secured Party to the contrary, to prosecute in a commercially reasonable manner
any Person infringing any Patent or Copyright or any Person misappropriating any
Trade Secret Right, in each case to the extent that such infringement or
misappropriation, either individually or in the aggregate, could reasonably be
expected to have a Material Adverse Effect.

         4.5     Maintenance of Patents or Copyright. At its own expense,
                 -----------------------------------
Assignor shall as promptly as practicable pay all post-issuance fees required
pursuant to 35 U.S.C. ss.41 (and all foreign equivalent fees (if any), as
applicable) to maintain in force its rights under each Patent or Copyright,
absent prior written consent of the Secured Party (other than any such Patents
or Copyrights determined by Assignor, in the exercise of its reasonable business
judgment, to be no longer useful or advantageous to the ongoing conduct of its
business).

         4.6      Prosecution of Patent Applications. At its own expense,
                  ----------------------------------
Assignor shall in a commercially reasonable manner prosecute all material
applications for (i) United States and foreign Patents listed in Annex C hereto
and (ii) Copyrights listed on Annex D hereto, in each case for Assignor and
shall not abandon any such application prior to exhaustion of all administrative
and judicial remedies (other than applications determined by Assignor, in the
exercise of its reasonable business judgment, to be no longer useful or
advantageous to the ongoing conduct of its business), absent written consent of
the Secured Party.

         4.7      Other Patents and Copyrights. Within 10 days of the
                  ----------------------------
acquisition of a United States or foreign Patent or acquisition of a registered
Copyright, other than such Patents or Copyrights issued to Assignor upon the
filing of an application for Copyright or Patent with the relevant United States
or foreign office, which are addressed in Section 4.2 hereof, Assignor shall
deliver to the Secured Party a copy of said Copyright or certificate or
registration of, said Patents, as the case may be, with an assignment for
security as to such Patent or Copyright, as the case may be, to the Secured
Party and at the expense of Assignor, confirming the assignment for security,
the form of such assignment for security to be substantially in the form of
Annex F or G hereto, as appropriate, or in such other form as may be reasonably
satisfactory to the Secured Party.

         4.8      No Restrictions from Third Party Licensors. Assignor hereby
                  ------------------------------------------
represents and warrants that none of the Collateral with respect to which it
owns a Copyright involves any license or licenses granted by third party
licensors that impose any restriction upon the grant of a security interest in
such Copyright or the ownership transfer or sale of such Copyright to Secured
Party or any designee or assignee thereof.

         4.9      Remedies. If an Event of Default shall occur and be
                  --------
continuing, the Secured Party may, by written notice to Assignor, take any or
all of the following actions: (i) declare the entire right, title, and interest
of Assignor in each of the Patents and Copyrights vested in the Secured Party in
which event such right, title, and interest shall immediately vest in the
Secured Party in which case the Secured Party shall be entitled to exercise the
power of attorney referred to in Section 4.1 hereof to execute, cause to be
acknowledged and notarized and to record said absolute assignment with the
applicable agency; (ii) take and practice or sell the Patents and Copyrights;
and (iii) direct Assignor to refrain, in which event Assignor shall refrain,
from

                                       7

<PAGE>

practicing the Patents and using the Copyrights directly or indirectly, and
Assignor shall execute such further documents as the Secured Party may
reasonably request further to confirm this and to transfer ownership of the
Patents and Copyrights to the Secured Party.

                                   ARTICLE V
               SPECIAL PROVISIONS CONCERNING ELIGIBLE RECEIVABLES

         5.1      Additional Representations and Warranties. As of the time when
                  -----------------------------------------
each of its Eligible Receivables arises, Assignor shall be deemed to have
represented and warranted that each such Eligible Receivable, and all records,
papers and documents relating thereto (if any) are genuine and what they purport
to be, and that all papers and documents (if any) relating thereto (i) will, to
the knowledge of Assignor, represent the genuine, legal, valid and binding
obligation of the account debtor evidencing indebtedness unpaid and owed by the
respective account debtor arising out of the performance of labor or services or
the sale or lease and delivery of the merchandise listed therein, or both, (ii)
will be the only original writings evidencing and embodying such obligation of
the account debtor named therein (other than copies created for general
accounting purposes), (iii) will, to the knowledge of Assignor, evidence true
and valid obligations, enforceable in accordance with their respective terms,
and (iv) will be in compliance and will conform in all material respects with
all applicable federal, state and local laws and applicable laws of any relevant
foreign jurisdiction.

         5.2      Maintenance of Records. Assignor will keep and maintain at its
                  ----------------------
own cost and expense accurate records of its Eligible Receivables, including,
but not limited to, originals of all documentation with respect thereto, records
of all payments received, all credits granted thereon, all merchandise returned
and all other dealings therewith, and Assignor will make the same available on
Assignor's premises to Secured Party for inspection, at Assignor's own cost and
expense, at any and all reasonable times upon prior notice to Assignor. Upon the
occurrence and during the continuance of an Event of Default and at the request
of Secured Party, Assignor shall, at its own cost and expense, deliver all
tangible evidence of its Eligible Receivables (including, without limitation,
all documents evidencing the Eligible Receivables) and such books and records to
Secured Party or to its representatives (copies of which evidence and books and
records may be retained by Assignor). Assignor shall legend, in form and manner
satisfactory to Secured Party, the Eligible Receivables, as well as books,
records and documents (if any) of Assignor evidencing or pertaining to such
Eligible Receivables, with an appropriate reference to the fact that such
Eligible Receivables have been assigned to Secured Party and that Secured Party
has a security interest therein.

         5.3      Direction to Account Debtors; etc. Upon the occurrence and
                  ----------------------------------
during the continuance of an Event of Default, if Secured Party so directs
Assignor, Assignor agrees (x) to cause all payments on account of the Eligible
Receivables to be made directly to Secured Party, (y) that Secured Party may, at
its option, directly notify the obligors with respect to any Eligible
Receivables to make payments with respect thereto as provided in the preceding
clause (x), and (z) that Secured Party may enforce collection of any such
Eligible Receivables and may adjust, settle or compromise the amount of payment
thereof, in the same manner and to the same extent as Assignor. Without notice
to or assent by any Assignor, Secured Party may, upon the occurrence and during
the continuance of an Event of Default, apply any or all amounts received by
Secured Party on account of the Eligible Receivables toward the payment of the
Obligations

                                       8

<PAGE>

in the manner provided in Section 7.4 of this Agreement. The reasonable costs
and expenses (including reasonable attorneys' fees) of collection, whether
incurred by Assignor or Secured Party, shall be borne by Assignor. The Secured
Party shall deliver a copy of such notice referred to in the preceding clause
(y) to Assignor, provided that the failure by Secured Party to so notify
Assignor shall not affect the effectiveness of such notice or the other rights
of Secured Party created by this Section 5.3.

         5.4      Modification of Terms; etc. Except in accordance with
                  ---------------------------
Assignor's ordinary course of business and consistent with reasonable business
judgment, Assignor shall not rescind or cancel any indebtedness evidenced by any
Eligible Receivable, or modify any term thereof or make any adjustment with
respect thereto, or extend or renew the same, or compromise or settle any
material dispute, claim, suit or legal proceeding relating thereto, or sell any
Eligible Receivable, or interest therein, without the prior written consent of
Secured Party. Assignor will not do anything to impair the rights of Secured
Party in the Eligible Receivables.

         5.5      Collection. Assignor shall endeavor in accordance with
                  ----------
reasonable business practices to cause to be collected from the account debtor
named in each of its Eligible Receivables, as and when due (including, without
limitation, amounts which are delinquent, such amounts to be collected in
accordance with generally accepted lawful collection procedures) any and all
amounts owing under or on account of such Eligible Receivable, and apply
forthwith upon receipt thereof all such amounts as are so collected to the
outstanding balance of such Eligible Receivable. Except as otherwise directed by
Secured Party after the occurrence and during the continuation of an Event of
Default, Assignor may allow in the ordinary course of business as adjustments to
amounts owing under its Eligible Receivables (i) an extension or renewal of the
time or times of payment, or settlement for less than the total unpaid balance,
which Assignor finds appropriate in accordance with reasonable business judgment
and (ii) a refund or credit due as a result of returned or damaged merchandise
or improperly performed services or for other reasons which Assignor finds
appropriate in accordance with reasonable business judgment. The reasonable
costs and expenses (including, without limitation, reasonable attorneys' fees)
of collection, whether incurred by Assignor or Secured Party, shall be borne by
Assignor.

         5.6      Assignor Remains Liable Under Receivables. Anything herein to
                  -----------------------------------------
the contrary notwithstanding, Assignor shall remain liable under each of the
Eligible Receivables to observe and perform all of the conditions and
obligations to be observed and performed by it thereunder, all in accordance
with the terms of any agreement giving rise to such Eligible Receivables.
Secured Party shall not have any obligation or liability under any Eligible
Receivable (or any agreement giving rise thereto) by reason of or arising out of
this Agreement or the receipt by Secured Party of any payment relating to such
Eligible Receivable pursuant hereto, nor shall Secured Party be obligated in any
manner to perform any of the obligations of any Assignor under or pursuant to
any Eligible Receivable (or any agreement giving rise thereto), to make any
payment, to make any inquiry as to the nature or the sufficiency of any payment
received by them or as to the sufficiency of any performance by any party under
any Eligible Receivable (or any agreement giving rise thereto), to present or
file any claim, to take any action to enforce any performance or to collect the
payment of any amounts which may have been assigned to them or to which they may
be entitled at any time or times.

                                   ARTICLE VI
                      PROVISIONS CONCERNING ALL COLLATERAL

         6.1      Protection of Secured Party's Security. Except as expressly
                  --------------------------------------
permitted hereunder, Assignor will do nothing to impair the rights of the
Secured Party in the Collateral. Assignor assumes all liability and
responsibility in connection with the Collateral acquired by it and the
liability of Assignor to pay the Obligations shall in no way be affected or
diminished by reason of the fact that such Collateral may be for any reason
whatsoever unavailable to Assignor.

         6.2      Further Actions. Assignor will, at its own expense and upon
                  ---------------
the reasonable request of the Secured Party, make, execute, endorse,
acknowledge, file and/or deliver to the Secured Party 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, 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 Secured Party deems reasonably appropriate or advisable to perfect,
preserve or protect its security interest in the Collateral.

         6.3      Financing Statements or Other Notices. Assignor agrees to
                  -------------------------------------
execute and deliver to the Secured Party such financing statements or other
notices, in form reasonably acceptable to the Secured Party, as the Secured
Party may from time to time reasonably request or as are reasonably necessary or
desirable in the opinion of the Secured Party to establish and maintain a valid,
enforceable, first priority perfected security interest in the Collateral as
provided herein and the other rights and security contemplated hereby. Assignor
will pay any applicable filing fees, recordation taxes and related expenses
relating to its Collateral. Assignor hereby authorizes the Secured Party to file
any such financing statements or other notices without the signature of Assignor
where permitted by law.

                                  ARTICLE VII
                 REMEDIES UPON OCCURRENCE OF AN EVENT OF DEFAULT

         7.1      Remedies; Obtaining the Collateral Upon Default. Assignor
                  -----------------------------------------------
agrees that, if any Event of Default shall have occurred and be continuing, then
and in every such case, the Secured Party, in addition to any rights now or
hereafter existing under applicable law and under the other provisions of this
Agreement, shall have all rights as a secured creditor under any UCC, and such
additional rights and remedies to which a secured creditor is entitled under the
laws in effect in all relevant jurisdictions and may:

         (a)      personally, or by agents or attorneys, immediately take
                  possession of the Collateral or any part thereof, from
                  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 Assignor's premises where any of
                  the Collateral is located and remove the same and use in
                  connection with such removal any and all services, supplies,
                  aids and other facilities of Assignor;

                                       10

<PAGE>

         (b)      instruct the obligor or obligors on any agreement, instrument
                  or other obligation constituting the Collateral (including,
                  without limitation, the Eligible Receivables) to make any
                  payment required by the terms of such agreement, instrument or
                  other obligation directly to Secured Party and may exercise
                  any and all remedies of Assignor in respect of such
                  Collateral;

         (c)      sell, assign or otherwise liquidate any or all of the
                  Collateral or any part thereof in accordance with Section 6.2
                  hereof, or direct Assignor to sell, assign or otherwise
                  liquidate any or all of the Collateral or any part thereof,
                  and, in each case, take possession of the proceeds of any such
                  sale or liquidation;

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

             (i)      forthwith cause the same to be moved to the place or
places so designated by the Secured Party and there delivered to the Secured
Party;

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

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

         (e)      license or sublicense, whether on an exclusive or nonexclusive
                  basis, any Marks, Patents or Copyrights included in the
                  Collateral for such term and on such conditions and in such
                  manner as the Secured Party shall in its sole judgment
                  determine;

it being understood that 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 Secured Party shall be entitled to a
decree requiring specific performance by Assignor of said obligation.

         7.2      Remedies; Disposition of the Collateral. If any Event of
                  ---------------------------------------
Default shall have occurred and be continuing, then any Collateral repossessed
by the Secured Party under or pursuant to Section 7.1 hereof and any other
Collateral whether or not so repossessed by the Secured Party, 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 Secured Party 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 Secured Party or
after any overhaul or repair at the expense of Assignor which the Secured Party
shall determine to be commercially reasonable. Any such disposition which shall
be a private sale or other private proceedings permitted by such requirements
shall be made upon not less

                                       11

<PAGE>

than 10 days' prior written notice to Assignor specifying the time at which such
disposition is to be made and the intended sale price or other consideration
therefor, and shall be subject, for the 10 days after the giving of such notice,
to the right of Assignor or any nominee of 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' prior written notice to 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 Secured Party's option, be subject to
reserve), after publication of notice of such auction (where required by
applicable law) not less than 10 days prior thereto. The 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
sale may be so adjourned. To the extent permitted by any such requirement of
law, the Secured Party 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 Assignor. If, under applicable law, the Secured Party shall be
permitted to make disposition of the Collateral within a period of time which
does not permit the giving of notice to Assignor as hereinabove specified, the
Secured Party need give Assignor only such notice of disposition as shall be
reasonably practicable in view of such applicable law. Assignor agrees to do or
cause to be done all such other acts and things as may be reasonably necessary
to make such sale or sales of all or any portion of the Collateral valid and
binding and in compliance with any and all applicable laws, regulations, orders,
writs, injunctions, decrees or awards of any and all courts, arbitrators or
governmental instrumentalities, domestic or foreign, having jurisdiction over
any such sale or sales, all at Assignor's expense.

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

         (a)      all damages occasioned by such taking of possession except any
                  damages which are the direct result of the Secured Party's
                  gross negligence or willful misconduct (as determined by a
                  court of competent jurisdiction in a final and non-appealable
                  decision);

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

         (c)      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 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.

                                       12

<PAGE>

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 Assignor therein and thereto, and shall
be a perpetual bar both at law and in equity against 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 Assignor.

         7.4      Application of Proceeds. All moneys collected by the Secured
                  -----------------------
Party upon any sale or other disposition of the Collateral, together with all
other moneys received by the Secured Party hereunder, shall be applied as
follows:

          (a)     to the payment of all amounts owing the Secured Party of the
                  type described in clauses (ii) and (iii) of the definition of
                  "Obligations";

          (b)     to the extent proceeds remain after the application pursuant
                  to the preceding clause (a), an amount equal to the
                  outstanding Primary Obligations shall be paid to the Secured
                  Party;

          (c)     to the extent proceeds remain after the application pursuant
                  to the preceding clauses (a), and (b), an amount equal to the
                  outstanding Secondary Obligations shall be paid to the Secured
                  Party; and

          (d)     to the extent proceeds remain after the application pursuant
                  to the preceding clauses (a) through (c), inclusive, and
                  following the termination of this Agreement pursuant to
                  Section 10.8(a) hereof, to Assignor or to whomever may be
                  lawfully entitled to receive such surplus.

         7.5      Remedies Cumulative. Each and every right, power and remedy
                  -------------------
hereby specifically given to the Secured Party shall be in addition to every
other right, power and remedy specifically given to the Secured Party under this
Agreement, the Note or now or hereafter existing at law, in equity or by statute
and each and every right, power and remedy whether specifically herein given or
otherwise existing may be exercised from time to time or simultaneously and as
often and in such order as may be deemed expedient by the Secured Party. All
such rights, powers and remedies shall be cumulative and the exercise or the
beginning of the exercise of one shall not be deemed a waiver of the right to
exercise any other or others. No delay or omission of the Secured Party in the
exercise of any such right, power or remedy and no renewal or extension of any
of the Obligations shall impair any such right, power or remedy or shall be
construed to be a waiver of any Default or Event of Default or an acquiescence
therein. No notice to or demand on any Assignor in any case shall entitle it to
any other or further notice or demand in similar or other circumstances or
constitute a waiver of any of the rights of the Secured Party to any other or
further action in any circumstances without notice or demand. In the event that
the Secured Party shall bring any suit to enforce any of its rights hereunder
