               SECTION 4.3.   SOLVENCY; NO LIENS.  The Borrower is Solvent and
will be Solvent upon the completion of all transactions contemplated to occur

governmental proceedings which would not, in the aggregate, have a Material
Adverse Effect on the Borrower.

               SECTION 4.5.   NO DEFAULTS.  The Borrower is not in default or
has not received a notice of default under any material contract, lease, or

permitted herein, none of the Collateral is subject to contractual obligations
that may restrict or inhibit the Lender's rights or abilities to sell or dispose

information are dated or certified and not incomplete by omitting to state any
material fact necessary to make such data, reports, and information not

Adverse Effect and which have not been specified herein, in the Financial
Statements, or in any certificate, opinion, or other


                                       5

written statement previously furnished by the Borrower to the Lender.

the same general lines of business as those presently conducted or proposed to
be conducted by it, and (d) comply with all applicable laws and regulations of
any federal, state, or local governmental authority, except for such laws and

any event within five Business Days after the Borrower learns of the following,

the aggregate, (b) any contract that is terminated or amended and which has had
or could reasonably be expected to have a Material Adverse Effect on the
Borrower, (c) the occurrence of any Material Adverse Change with respect to the

Event of Default, for the purpose of inspecting the Collateral and any and all
records pertaining thereto.

               Section 5.4.   INSURANCE.  The Borrower will maintain insurance
on the Collateral under such policies of insurance, with such insurance
companies, in such amounts, and covering such risks as are at all times
satisfactory to the Lender.  All such policies shall be made payable to the
Lender, in case of loss, under a standard non-contributory "lender" or "secured
party" clause and are to contain such other provisions as the Lender may
reasonably require to protect the Lender's interests in the Collateral and to
any payments to be made under such policies.  Certificates of insurance policies
are to be delivered to the Lender, premium prepaid, with the loss payable
endorsement in the Lender's favor, and shall provide for not less than thirty
days' prior written notice to the Lender, of any alteration or cancellation of
coverage.  If the Borrower fails to maintain such insurance, the Lender may
arrange for (at the Borrower's expense and without any responsibility on the
Lender's part for) obtaining the insurance.  Unless the Lender shall otherwise
agree with the Borrower in writing, the Lender shall have the right, in the name
of the Lender or the Borrower, to file claims under any insurance policies, to
receive and give acquittance for any payments that may be payable thereunder,
and to execute any endorsements, receipts, releases, assignments, reassignments,
or other documents that may be necessary to effect the collection, compromise,
or settlement of any claims under any such insurance policies. 

               SECTION 5.5.   TAXES.  The Borrower will pay, when due, all
taxes, assessments, claims, and other charges ("Taxes") lawfully levied or
assessed against the Borrower or the Collateral other than taxes that are being
diligently contested in good faith by the Borrower by appropriate proceedings
promptly instituted and for which an adequate reserve is being maintained by the
Borrower in accordance with GAAP.  If any Taxes remain unpaid after the date
fixed for the payment thereof, or if any lien shall be claimed therefor, then,
without notice to the Borrower, but on the Borrower's behalf, the Lender may pay
such Taxes, and the amount thereof shall be included in the Obligations.

office other than Permitted Liens.  The Borrower shall promptly pay, when
payable, all transportation, storage, and warehousing charges and license fees,
registration fees, assessments, charges, permit fees, and taxes (municipal,
state, and federal) which may now or hereafter be imposed upon the ownership,
leasing, renting, possession, sale, or use of the Collateral, other than taxes
on or measured by the Lender's income and fees, assessments, charges, and taxes
which are being contested in good faith by appropriate proceedings diligently
conducted and with respect to which adequate reserves are maintained to the
extent required by GAAP.

               SECTION  5.7.  NO CHANGE OF LOCATION, STRUCTURE, OR IDENTITY. 
The Borrower will not (a) change the location of its chief executive office or
establish any place of business other than those specified herein or (b) move or
permit the movement of any item of Collateral from the location specified in the
applicable Schedule, except that the Borrower may change its chief executive
office and keep Collateral at other locations within the United States provided
that the Borrower has delivered to the Lender (i) prior written notice thereof
and (ii) duly executed financing statements and other agreements and instruments
(all in form and substance satisfactory to the Lender) necessary or, in the
opinion of the Lender, desirable to perfect and maintain in favor of the Lender
a first or second priority security interest, as applicable, in the Collateral. 
Notwithstanding anything to the contrary in the immediately preceding sentence,
the Borrower may keep any Collateral consisting of motor vehicles, notebook
computers, field testing equipment and mobile communications devices or rolling
stock at any location in the United States provided that the Lender's security
interest in any such Collateral is conspicuously marked on the certificate of
title thereof and the Borrower has complied with the provisions of Section 5.9.

               SECTION 5.8.   USE OF COLLATERAL; LICENSES; REPAIR.  The
Collateral shall be operated by competent, qualified personnel in connection
with the Borrower's business purposes, for the purpose for which the Collateral
was designed and in accordance with applicable operating instructions, laws, and
government regulations, and the Borrower shall use every reasonable precaution
to prevent loss or damage to the Collateral from fire and other hazards. The
Borrower shall procure and maintain in effect all orders, licenses,
certificates, permits, approvals, and consents required by federal, state, or
local laws or by any governmental body, agency, or authority in connection with
the delivery, installation, use, and operation of the Collateral.  

               SECTION 5.9.   FURTHER ASSURANCES.  The Borrower will, promptly
upon request by the Lender, execute and deliver or use its best efforts to
obtain any document required by the Lender (including, without limitation,

or subordination agreements with respect to the Obligations and the Collateral),
give any notices, execute and file any financing statements, mortgages, or other
documents (all in form and substance satisfactory to the Lender), mark any
chattel paper, deliver any chattel paper or instruments to the Lender, and take
any other actions that are necessary or, in the opinion of the Lender, desirable
to perfect or continue the perfection and the first priority of the Lender's
security interest in the Collateral, to protect the Collateral against the
rights, claims, or interests of any Persons, or to effect the purposes of this
Agreement.  The Borrower hereby authorizes the Lender to file one or more
financing or continuation statements, and amendments thereto, relating to all or
any part of the Collateral without the signature of the Borrower where permitted
by law.  A carbon, photographic, or other reproduction of this Agreement or any
financing statement covering the Collateral or any part thereof shall be
sufficient as a financing statement where permitted by law.  To the extent
required under this Agreement, the Borrower will pay all costs incurred in
connection with any of the foregoing.

               SECTION 5.10.  NO DISPOSITION OF COLLATERAL.  The Borrower will
not in any way hypothecate or create or permit to exist any lien, security
interest, charge, or encumbrance on or other interest in any of the Collateral,
except for the lien and security interest granted hereby and Permitted Liens
which are junior to the lien and security interest of the Lender, and the
Borrower will not sell, transfer, assign, pledge, collaterally assign, exchange,
or otherwise dispose of any of the Collateral.  In the event the Collateral, or
any part thereof, is sold, transferred, assigned, exchanged, or otherwise
disposed of in violation of these provisions, the security interest of the
Lender shall continue in such Collateral or part thereof notwithstanding such
sale, transfer, assignment,


                                       7

<PAGE>


exchange, or other disposition, and the Borrower will hold the proceeds thereof
in a separate account for the benefit of the Lender.  Following such a sale, the
Borrower will transfer such proceeds to the Lender in kind.

               SECTION 5.11.  NO LIMITATION ON LENDER'S RIGHTS.  Except for
contracts in the ordinary course of business (including government contracts,
technology licensing agreements and joint venture agreements), the Borrower will
not enter into any contractual obligations which may restrict or inhibit the
Lender's rights or ability to sell or otherwise dispose of the Collateral or any
part thereof.

               SECTION 5.12.  PROTECTION OF COLLATERAL.  Upon notice to the
Borrower (provided that if an Event of Default has occurred and is continuing
the Lender need not give any notice), the Lender shall have the right at any
time to make any payments and do any other acts the Lender may deem necessary to
protect its security interests in the Collateral, including, without limitation,
the rights to satisfy, purchase, contest, or compromise any encumbrance, charge,
or lien which, in the reasonable judgment of the Lender, appears to be prior to
or superior to the security interests granted hereunder, and appear in, and
defend any action or proceeding purporting to affect its security interests in,
or the value of, any of the Collateral.  The Borrower hereby agrees to reimburse
the Lender for all payments made and expenses incurred under this Agreement
including fees, expenses, and disbursements of attorneys and paralegals
(including the allocated costs of in-house counsel) acting for the Lender,
including any of the foregoing payments under, or acts taken to protect its
security interests in, any of the Collateral, which amounts shall be secured
under this Agreement, and agrees it shall be bound by any payment made or act
taken by the Lender hereunder absent the Lender's gross negligence or willful
misconduct.  Notwithstanding the foregoing, the Lender shall have no obligation
to make any of the foregoing payments or perform any of the foregoing acts or to
participate in or perform any act relating to any litigation involving
Borrower's Intellectual Property Collateral (as defined in the Intellectual
Property Agreement).

               SECTION 5.13.  DELIVERY OF ITEMS.  The Borrower will (a) promptly

property included in the Collateral, and any promissory notes, letters of credit
or instruments related to or otherwise in connection with any property included
in the Collateral, which in any such case come into the possession of the
Borrower, or shall cause the issuer thereof to deliver any of the same directly
to the Lender, in each case with any necessary endorsements in favor of the

amendment or modification and within ten days before such amendment or
modification delivers executed Uniform Commercial Code financing statements (in
form and substance satisfactory to the Lender) or (b) merge or consolidate with
any other entity or make any material change in its capital structure, in each
case without the Lender's prior written consent which shall not be unreasonably
withheld, provided, however, that nothing herein shall prevent Borrower from

discharges all of its Obligations hereunder at or before the closing of such
transaction.

               SECTION 5.16.  ADDITIONAL REQUIREMENTS.  The Borrower shall take

involuntary proceeding, such proceeding remains undismissed or unstayed for
forty-five days following the commencement thereof, or any action by the
Borrower is taken authorizing any such proceedings;

bonded, or discharged within sixty days;

               (k)    any material covenant, agreement, or obligation, as

rights under any Loan Document or Applicable Law, declare all Obligations to be
immediately due and payable (except with respect to any Event of Default set
forth in Section 7(f) hereof, in which case all Obligations shall automatically
become immediately due and payable without necessity of any declaration) without
presentment, representation, demand of payment, or protest, which are hereby
expressly waived.

               (b)    The Lender may take possession of the Collateral and, for
that purpose may enter, with the aid and assistance of any person or persons,

               (d)    The Lender may exercise in respect of the Collateral, in
addition to other rights and remedies provided for herein (or in any Loan
Document) or otherwise available to it, all the rights and remedies of a secured
party under the applicable Uniform Commercial Code (the "Code") whether or not
the Code applies to the affected Collateral and also may (i) require the
Borrower to, and the Borrower hereby agrees that it will at its expense and upon
request of the Lender forthwith, assemble all or part of the  Collateral as
directed by the Lender and make it available to the Lender at a place to be
designated by the Lender that is reasonably convenient to both parties and
(ii) without notice except as specified below, sell the Collateral or any part
thereof in one or more parcels at public or private sale, at any of the Lender's
offices or elsewhere, for cash, on credit, or for future delivery, and upon such
other terms as the Lender may deem commercially reasonable.  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 make any sale of Collateral
regardless of notice of sale having been given.  The Lender may adjourn any
public or private sale from time to time by announcement at the time and place
fixed therefor, and such sale may, without further notice, be made at the time
and place to which it was so adjourned.

               (e)    All cash proceeds received by the Lender in respect of
any sale of, collection from, or other realization upon all or any part of the
Collateral may, in the discretion of the Lender, be held by the Lender as
collateral for, or then or at any time thereafter applied in whole or in part by
the Lender against, all or any part of the Obligations in such order as the
Lender shall elect.  Any surplus of such cash or cash proceeds held by the
Lender and remaining after the full and final payment of all the Obligations
shall be paid over to the Borrower or to such other Person to which the Lender
may be required under applicable law, or directed by a court of competent
jurisdiction, to make payment of such surplus.

and

      WHEREAS, in connection with the Master Agreement, the Debtor is 
required to grant to the Secured Party a security interest in and lien on 
substantially all of its assets; and

      WHEREAS, it is a condition precedent to the effectiveness of the 
Master Agreement that the Debtor shall have executed and delivered this 
Agreement and granted a security interest in all of the Debtor's right, title 
and interest in and to all of the Intellectual Property Collateral (as

      NOW, THEREFORE, in consideration of the premises hereof and to induce 
the Secured Party to enter into the Master Agreement, and for other good and

(hereinafter collectively referred to as the "Copyrights"). All copyright 
registrations and all currently pending copyright applications owned or

trade secrets, improvements, processes, methods, formulae, applications, 
ideas, know-how, customer lists, corporate and other business records, license 
rights, advertising materials, operating manuals, sales literature, drawings, 
specifications, descriptions, name plates, catalogues, dealer contracts, 
supplier contracts, distributor agreements, confidential information, 
consulting agreements, engineering contracts, proprietary information, and 
goodwill (and all other assets which uniquely reflect such goodwill), and to 
all income, royalties, damages and payments now and hereafter due or payable 
therefor or in respect thereof (collectively, the "Proprietary Information" 
and, together with the Patents, the Trademarks and the Copyrights, the 
"Intellectual Property Collateral").

      SECTION 2.  REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE DEBTOR.

          (a)  The Debtor is and will continue to be the owner of all of the 
Intellectual Property Collateral, free from any adverse claim, security 
interest, lien or encumbrance in favor of any Person except for the security 
interest granted to the Secured Party and except for (i) the prior lien of 
Silicon Valley Bank and (ii) Permitted Liens.

          (b)  None of the Intellectual Property Collateral is or shall 
become subject to any Lien in favor of any Person other than the Secured 
Party and except for any Permitted Liens, and the Debtor agrees that it shall 
not license, transfer, convey or encumber any interest in or to the 
Intellectual Property Collateral. Notwithstanding the foregoing, the Debtor 
shall be permitted to license any of the Intellectual Property Collateral in 
the ordinary course of business on commercially reasonable terms and 
conditions. Any license of the Intellectual Property Collateral granted by 
the Debtor (each, a "License") shall be in writing and shall reserve all 
rights in the Debtor except those reasonably necessary in the ordinary course 
of business to fulfill the permitted purposes herein. The Debtor shall cause 
a copy of each License to be delivered to the Secured Party within thirty (30) 
days of execution by all parties thereto.

          (c)  Except as disclosed in Schedule D hereto, the Debtor has made 
no previous assignment, transfer or agreement materially in conflict herewith 
or constituting a present or future assignment, transfer, or encumbrance of 
any of the Intellectual Property Collateral.

                                      2

<PAGE>

          (d)  Except as disclosed in Schedule D hereto, there is no 
financing statement or other document or instrument now signed or on file in 
any public office granting a security interest in or otherwise encumbering 
any part of the Intellectual Property Collateral, except those showing the 
Secured Party as secured party. So long as any Obligations remain 
outstanding, the Debtor will not execute, and there will not be on file in any 
public office, any such financing statement or other document or instruments, 
except financing statements filed or to be filed in favor of the Secured 
Party or pursuant to a transaction permitted by the second sentence of 
Section 2(b).

          (e)  Subject to any limitation stated therein or in connection 
therewith, all information furnished to the Secured Party concerning the 
Intellectual Property Collateral and proceeds thereof is and will be accurate 
and correct in all material respects.

          (f)  Except as disclosed in Schedule D hereto, all Intellectual 
Property Collateral consisting of applications for Patents and for 
registrations of Trademarks and Copyrights has been duly and properly filed 
and all Intellectual Property Collateral consisting of issued or granted 
Patents and of registrations of Trademarks and Copyrights (including, 
without limitation, any and all renewals, reissues, continuations or divisions 
thereof, as the case may be) has been duly and properly maintained.

          (g)  Promptly, but not more frequently than quarterly, upon the 
receipt of an official filing receipt indicating that a patent application or 
an application for registration of a trademark has been received by the U.S. 
Patent and Trademark Office or an application for registration of a copyright 
has been received by the U.S. Copyright Office and upon the issuance of any 
patent or of any trademark or copyright registration, the Debtor agrees to 
notify the Secured Party in writing, which notice shall identify such patent, 
trademark or copyright application or patent, trademark or copyright 
registration, and the Debtor shall execute all documents necessary to perfect 
a security interest in such patent, trademark or copyright application or 
such patent or trademark or copyright registration, and the Debtor shall 
annually, or more frequently as the Secured Party shall request, cause an 
instrument sufficient to perfect, protect or establish any Lien hereunder to 
be recorded in the U.S. Patent and Trademark Office with respect to all 
United States patent applications filed by it or patents issued to it during 
the prior calendar year and with respect to all trademark applications filed 
by it or trademark registrations issued to it during the prior calendar year, 
and the Debtor shall annually, or more frequently as the Secured Party shall 
request, cause an instrument sufficient to perfect, protect or establish any 
Lien hereunder to be recorded in the U.S. Copyright Office with respect to 
United States copyright applications filed by it or copyright registrations 
issued to it during the prior calendar year.

          (h)  The Debtor shall not take any action, or permit any action to 
be taken by others subject to the Debtor's control, including licensees, or 
fail to take any action, or permit others subject to the Debtor's control, 
including licensees, to fail to take any action, subject to the provisions of 
Section 2(g), which would, in the case of any such actions or failures to act 
taken singly or together, materially adversely affect the validity, grant and 
enforceability of the security interest granted to the Secured Party 
hereunder. Notwithstanding the foregoing, the Debtor shall be permitted to 
abandon any of the Trademarks in accordance with the terms of Section 2(l).

          (i)  The Debtor shall promptly notify the Secured Party, in 
writing, of any suit, action, proceeding, claim or counterclaim brought 
against the Debtor that would reasonably be expected to have a Material 
Adverse Effect on the Intellectual Property Collateral, and shall, on 
request, deliver to the Secured Party a copy of all pleadings, papers, orders 
or decrees theretofore and thereafter filed in any such suit, action or 
proceeding, and shall keep the Secured Party duly advised in writing of the 
progress of any such suit.

          (j)  To the best knowledge and belief of the Debtor, except as 
disclosed in Schedule D, no infringement or unauthorized use presently is 
being made of any Intellectual Property Collateral. In the event of any 
material infringement of the Intellectual Property Collateral by others or in 
the event of any other conduct detrimental to the Intellectual Property 
Collateral by others known or brought to the attention of the Debtor, the 
Debtor shall promptly notify the Secured Party in writing at its address set 
forth in Section 5(a) of such infringement or other conduct and the full 
nature, extent, evidence and facts of such infringement or other conduct 
known to the Debtor.

          (k)  If reasonably requested by the Secured Party, the Debtor shall 
provide the Secured Party a complete status report of all Intellectual 
Property Collateral. Upon request by the Secured Party, the Debtor shall 
deliver to counsel for the Secured Party copies of any such Intellectual 
Property Collateral and other

                                       3

<PAGE>

documents concerning or related to the prosecution, protection, maintenance, 
enforcement and issuance of the Intellectual Property Collateral.

          (l)  The Debtor shall notify the Secured Party in writing at the 
address set forth in Section 5(a) at least thirty (30) days prior to any 
proposed voluntary abandonment of any Intellectual Property Collateral (other 
than items of Intellectual Property Collateral that are not useful or 
beneficial to the business and operations of the Debtor) and obtain the prior 
written consent of the Secured Party to such abandonment.

          (m)  During the term of this Agreement, the Debtor agrees:

               (i)  whenever any of the registered Trademarks are used by or  
      on behalf of the Debtor, if reasonably practicable, to affix or cause to 
      be affixed a notice that the mark is a registered trademark or service 
      mark, which notice shall be in a form accepted or required by the 
      trademark marking laws of each country in which the mark is so used and 
      registered; and

              (ii)  whenever any of the underlying works covered by registered 
      Copyrights are used by or on behalf of the Debtor, if reasonably 
      practicable, to affix or cause to be affixed a notice that said 
      underlying works are so covered, which notice shall be in a form accepted
      or required by the copyright laws of such country in which said 
      underlying works are so used and registered.
      
          (n)  Subject to the provisions of Section 4(g), during the term of 
this Agreement, all income, royalties, payments and damages due and payable 
to the Debtor under or in respect of the Intellectual Property Collateral 
shall be paid to the Debtor.

          (o)  The Debtor agrees, upon the reasonable request by the Secured 
Party, during the term of this Agreement;

               (i)  to execute, acknowledge and deliver all additional 
      instruments and documents necessary or desirable to effect the purposes 
      and intents of this Agreement, in a form reasonably acceptable to 
      counsel the the Secured Party; and

              (ii)  to do all such other acts as may be necessary or 
      appropriate to carry out the purposes and intents of this Agreement, 
      and to create, evidence, perfect and continue the security interest of 
      the Secured Party in the Intellectual Property Collateral.

      SECTION 3.  INDEMNITY. The Debtor agrees to indemnify the Secured Party 
from and against any and all claims, losses and liabilities arising out of 
or resulting from this Agreement (including, without limitation, enforcement 
of this Agreement and any actions taken pursuant to Section 4 or any failure 
to act thereunder).

      SECTION 4.  RIGHTS AND REMEDIES UPON AN EVENT OF DEFAULT.

             (a)  If any Event of Default shall have occurred and be 
continuing, then and in every such case, subject to any mandatory 
Requirements of Law, the Secured Party, in addition to other rights and 
remedies provided for herein and any rights now or hereafter existing under 
applicable law, shall have all rights and remedies as a secured creditor 
under the Uniform Commercial Code in all relevant jurisdictions and may:
      
                  (i)  personally, or by agents or attorneys, immediately take 
      possession of the Intellectual Property Collateral or any part thereof, 
      from the Debtor 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 Debtor's premises where any of the Intellectual 
      Property Collateral is located and remove the same and use in 
      connection with such removal any and all services, supplies, aids and
      other facilities of the Debtor; and

                 (ii)  sell, assign or otherwise liquidate, or direct the 
      Debtor to sell, assign or otherwise liquidate, any or all of the 
      Intellectual Property Collateral or any part thereof, and take


                                       4

<PAGE>

      possession of the proceeds of any such sale or liquidation;

          (b)  Any collateral repossessed by the Secured Party under or 
pursuant to Section 4(a) and any other intellectual Property 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 Requirements of Law, 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 than 10 days' written notice to the Debtor 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 the Debtor or any nominee of the 
Debtor to acquire the Intellectual Property 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 Debtor 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 option of the Secured Party, be subject 
to reserve), after publication of notice of such auction not less than 10 
days prior thereto in two newspapers of general circulation in the 
jurisdiction in which such auction is to be held. To the extent permitted by 
any such Requirements of Law, the Secured Party may bid for and become the 
purchaser of the Intellectual Property Collateral or any item thereof, 
offered for sale in accordance with this Section without accountability to 
the Debtor (except to the extent of surplus money received). If, under 
mandatory Requirements of Law, the Secured Party shall be required to make 
disposition of the Intellectual Property Collateral within a period of time 
which does not permit the giving of notice to the Debtor as hereinabove 
specified, the Secured Party need give the Debtor only such notice of 
disposition as shall be reasonably practicable in view of such mandatory 
Requirements of Law. The Secured Party shall not be obligated to make any 
sale of Intellectual Property Collateral regardless of notice of sale having 
been given. The Secured Party may adjourn any public or private sale from 
time to time by announcement at the time and place fixed therefor, and such 
sale may, without further notice, be made at the time and place to which it 
was so adjourned.

          (c)  Upon the occurrence and continuance of an Event of Default, 
the Secured Party shall have the right at any time to make any payments and 
do any other acts the Secured Party may deem necessary to protect its 
security interests in the Intellectual Property Collateral, including, without 
limitation, the rights to pay, purchase, contest or compromise any Lien 
which, in the reasonable judgment of the Secured Party, appears to be prior 
to or superior to the security interests granted hereunder, and appear in and 
defend any action or proceeding purporting to affect its security interest 
in, or the value of, the Intellectual Property Collateral. The Debtor hereby 
agrees to reimburse the Secured Party for all payments made and expenses 
incurred under this Agreement including reasonable fees, expenses and 
disbursements of attorneys and paralegals acting for the Secured Party, 
including any of the foregoing payments under, or acts taken to protect its 
security interests in, the Intellectual Property Collateral, which amounts 
shall be secured under this Agreement, and agrees it shall be bound by any 
payment made or act taken by the Secured Party hereunder absent the Secured 
party's gross negligence or willful misconduct. The Secured Party shall have 
no obligation to make any of the foregoing payments or perform any of the 
foregoing acts.

          (d)  The Debtor hereby irrevocably authorizes and appoints the 
Secured Party, or any Person or agent the Secured Party may designate, as the 
Debtor's attorney-in-fact, with full authority in the place and stead of the 
Debtor and in the name of the Debtor or otherwise, at the Debtor's cost and 
expense, in the Secured Party's discretion, to take any action and to 
execute any instrument that the Secured Party may deem necessary or 
advisable to accomplish the purposes and intents of this Agreement and to 
exercise all of the following powers upon and at any time after the 
occurrence and during the continuance of an Event of Default, which powers, 
being coupled with an interest, shall be irrevocable until all of the 
Obligations shall have been paid and satisfied in full:

                (i)   ask for, demand, collect, bring suit, recover, 
      compromise, administer, accelerate or extend the time of payment,
      issue credits, compromise, receive and give acquittance and receipts for 
      moneys due and to become due under or in respect of any of the 
      Intellectual Property Collateral; the 

               (ii)   receive, take, endorse, negotiate, sign, assign and 
      deliver and collect any checks, notes, drafts or other instruments, 
      documents and chattel paper, in connection with clause (i)


                                       5

<PAGE>

      above;

               (iii)  receive, open and dispose of all mail addressed to the 
      Debtor and notify postal authorities to change the address for delivery 
      thereof to such address as the Secured Party may designate;

                (iv)  give customers indebted on the Intellectual Property 
      Collateral notice of the Secured Party's interest therein, or to instruct
      such customers to make payment directly to the Secured Party for the 
      Debtor's account or to request, at any time from customers indebted on 
      the Intellectual Property Collateral, verification of information 
      concerning the Intellectual Property Collateral and the amounts owing 
      thereon;

                 (v)  convey any item of Intellectual Property Collateral to 
      any purchaser thereof;

                (vi)  record any instruments under Section 2(g) hereof;

               (vii)  make any payments or take any acts under Section 4(c) 
      hereof; and

              (viii)  file any claims or take any action or institute any 
      proceedings that the Secured Party may reasonably deem necessary or 
      desirable for the collection of any of the Intellectual Property 
      Collateral or otherwise to enforce the rights of the Secured Party with 
      respect to any of the Intellectual Property Collateral.

The Secured Party's authority under this Section 4(d) shall include, without 
limitation, the authority to execute and give receipt for any certificate of 
ownership or any document, transfer title to any item of Intellectual 
Property Collateral, sign the Debtor's name on all financing statements or 
any other documents deemed necessary or appropriate to preserve, protect or 
perfect the security interest in the Intellectual Property Collateral and to 
file the same, prepare, file and sign the Debtor's name on any notice of 
Lien, assignment or satisfaction of Lien or similar document in connection 
with any Intellectual Property Collateral and prepare, file and sign the 
Debtor's name on a proof of claim in bankruptcy or similar document against 
any customer of the Debtor, and to take any other actions arising from or 
incident to the rights, powers and remedies granted to the Secured Party in 
this Agreement. This power of attorney is coupled with an interest and is 
irrevocable by the Debtor.

      (e)   All cash proceeds received by the Secured Party in respect of any 
sale of, collection from, or other realization upon all or any part of the 
Intellectual Property Collateral shall be applied by the Secured Party 
against the Obligations in such order as the Secured Party may determine.

      (f)  The Secured Party shall have the right of setoff with respect to 
the Intellectual Property Collateral as provided Section 9.14 of the Master 
Agreement.

      (g)  Upon the occurrence and during the continuance of an Event of 
Default, all income, royalties, payments and damages under or in respect of 
the Intellectual Property Collateral, if any, received thereafter shall be 
held by the Debtor in trust for the benefit of the Secured Party, separate 
from the Debtor's own property or funds and immediately turned over to the 
Secured Party with proper assignments or endorsements. Upon the occurrence 
and during the continuance of an Event of Default, the Secured Party shall 
have the right to notify payors of income, royalties, payments and damages 
under or in respect of the Intellectual Property Collateral to make payment 
directly to the Secured Party.

      (h)  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 under this Agreement or under the other Lease 
Documents or now or hereafter existing at law or 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 exercise of one shall not be deemed a waiver of 
the right to exercise of 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,


                                       6

<PAGE>

power or remedy or shall be construed to be a waiver of any Default or Event 
of Default or any acquiescence therein.

    SECTION 5. GENERAL PROVISIONS.

         (a) NOTICES. All notices, approvals, consents or other 
communications required or desired to be given hereunder shall be in writing

address or when delivery is refused and (iii) if sent by telecopier 
transmission, when receipt of such transmission is acknowledged.

         (b) HEADINGS. The headings in this Agreement are for purposes of 
reference only and shall not affect the meaning or construction of any 
provision of this Agreement.

         (c) SEVERABILITY. The provisions of this Agreement are severable, 
and if any clause or provision shall be held invalid or unenforceable in 
whole or in part in any jurisdiction, then such invalidity or 
unenforceability shall affect, in that jurisdiction only, such clause or 
provision, or part thereof, and shall not in any manner affect such clause or 
provision in any other jurisdiction or any other clause or provision of this 
Agreement in any jurisdiction.

         (d) AMENDMENTS, WAIVERS AND CONSENTS. Any amendment or waiver of any 
provision of this Agreement and any consent to any departure by the Debtor 
from any provision of this Agreement shall not be effective unless the same 
shall be in writing and signed by the Debtor and the Secured Party and then 
such waiver or consent shall be effective only in the specific instance and 
for the specific purpose for which given.

         (e) INTERPRETATION. Time is of the essence in each provision of this 
Agreement of which time is an element. All terms not defined herein or in the 
Master Agreement shall have the meaning set forth in the Code, except where 
the context otherwise requires. To the extent a term or provision of this 
Agreement conflicts with the Master Agreement and is not dealt with herein 
with more specificity, the Master Agreement shall control with respect to the 
subject matter of such term or provision. Acceptance of or acquiescence in a 
course of performance rendered under this Agreement shall not be relevant in 
determining the meaning of this Agreement even though the accepting or 
acquiescing party had knowledge of the nature of the performance and 
opportunity for objection.

         (f) CONTINUING SECURITY INTEREST. This Agreement shall create a 
continuing security interest in the Intellectual Property Collateral and 
shall (i) remain in full force and effect until the payment in full in cash 
of the Obligations and the termination of the Master Agreement, (ii) be 
binding upon the Debtor and its successors and assigns and (iii) inure, 
together with the rights and remedies of the Secured Party, to the Secured 
Party's successors, transferees and assigns. Without limited the generality 
of the foregoing clause (iii), the Secured Party may, in accordance with the 
terms of the Master Agreement, assign or otherwise transfer all or any 
portion of its rights and obligations under the Lease Documents (including, 
without limitation, all or any portion of any Leases or any Notes held by it) 
to any other Person, and such other Person shall thereupon become vested with 
all the benefits in respect thereof granted to the Secured Party herein or 
otherwise, in each case as provided in the Master Agreement.

         (g) REINSTATEMENT. To the extent permitted by law, this Agreement 
shall continue to be effective or be reinstated if at any time any amount 
received by the Secured Party in respect of the Obligations is rescinded or 
must otherwise be restored or returned by the Secured Party because the 
Debtor is the subject of an Insolvency Event, all as though such payments had 
not been made.

         (h) SURVIVAL OF PROVISIONS. All representations, warranties and 
covenants of the Debt or

                                      7

<PAGE>

contained herein shall survive the execution and delivery of this Agreement, 
and shall terminate only upon the full and final payment and performance by 
the Debtor of the Obligations secured hereby and termination of the Master 
Agreement and the other Lease Documents.

         (i) SECURED PARTY MAY PERFORM. If the Debtor fails to perform any 
agreement contained herein, the Secured Party may itself perform, or cause 
performance of, such agreement, and the expenses of the Secured Party 
incurred in connection therewith shall be payable by the Debtor and shall 
constitute Obligations secured by this Agreement.

         (j) NO DUTY ON SECURED PARTY. The powers conferred on the Secured 
Party hereunder are solely to protect the interest of the Lenders in the 
Intellectual Property Collateral and shall not impose any duty upon the 
Secured Party to exercise any such powers. Except for the safe custody of any 
Intellectual Property Collateral in its possession and the accounting for 
money actually received by it hereunder, the Secured Party shall have no 
duty as to Intellectual Property Collateral, as to ascertaining or taking 
action with respect to calls, conversions, exchanges, maturities, tenders or 
other matters related to any Intellectual Property Collateral, whether or not 
the Secured Party has or is deemed to have knowledge of such matters, or as 
to the taking of any necessary steps to preserve rights against any Person or 
any other rights pertaining to any Intellectual Property Collateral. The 
Secured Party shall be deemed to have exercised reasonable care in the 
custody and preservation of any Intellectual Property Collateral in its 
possession if such Intellectual Property Collateral is accorded treatment 
substantially equal to that which the Secured Party accords its own property. 
To the extent the Intellectual Property Collateral is held by a custodian, 
the Secured Party shall be deemed to have exercised reasonable case if it has 
selected the custodian with reasonable care.

         (k) DELAYS; PARTIAL EXERCISE OF REMEDIES. No delay or omission of the 
Secured Party to exercise any right or remedy hereunder, whether before or 
after the happening of any Event of Default, shall impair any such right or 
shall operate as a waiver thereof or as a waiver of any such Event of 
Default. No single or partial exercise by the Secured Party of any right or 
remedy shall preclude any other or further exercise thereof, or preclude any 
other right or remedy.

         (l) RELEASE; TERMINATION OF AGREEMENT. Subject to the provisions of 
subsection (g) hereof, upon the payment in full in cash of the Obligations 
and the termination of the Master Agreement, this Agreement shall terminate 
and all rights in the Intellectual Property Collateral shall revert to the 
Debtor. At such time, the Secured Party shall, upon the request and at the 
expense of the Debtor, (A) execute and deliver to the Debtor such documents 
as the Debtor shall reasonably request to evidence such termination and (B) 
reassign and redeliver to the Debtor all of the Intellectual Property 
Collateral hereunder which has not been sold, disposed of, retained or 
applied by the Secured Party in accordance with the terms hereof. Such 
reassignment and redelivery shall be without warranty by or recourse to the 
Secured Party, except as to the absence of any prior assignments by the 
Secured Party of its interest in the Intellectual Property Collateral.

         (m) COUNTERPARTS. This Agreement may be executed in one or more 
counterparts, each of which shall be deemed an original but both of which 
shall together constitute one and the same agreement.

         (n) GOVERNING LAW. THE VALIDITY, INTERPRETATION AND ENFORCEMENT OF 
THIS AGREEMENT SHALL BE GOVERNED BY THE LAWS OF THE STATE OF ILLINOIS, 
WITHOUT GIVING EFFECT TO CONFLICT OF LAW PRINCIPLES, EXCEPT TO THE EXTENT THAT 
FEDERAL LAW IS APPLICABLE.

         (o) SUBMISSION TO JURISDICTION. ALL DISPUTES BETWEEN THE DEBTOR AND 
THE SECURED PARTY, WHETHER SOUNDING IN CONTRACT, TORT, EQUITY OR OTHERWISE, 
SHALL BE RESOLVED ONLY BY STATE AND FEDERAL COURTS LOCATED IN CHICAGO, 
ILLINOIS AND THE COURTS TO WHICH AN APPEAL THEREFROM MAY BE TAKEN; PROVIDED, 
HOWEVER, THAT THE SECURED PARTY SHALL HAVE THE RIGHT, TO THE EXTENT PERMITTED 
BY APPLICABLE LAW, TO PROCEED AGAINST THE DEBTOR OR ITS PROPERTY IN ANY
