which such written  acknowledgement shall be in form and substance  satisfactory
to the Collateral Agent, (F) if at any time after the date hereof,  such Grantor
acquires or holds any Commercial Tort Claim,  promptly  notifying the Collateral
Agent in a writing signed by such Grantor  setting forth a brief  description of
such  Commercial  Tort Claim and  granting  to the  Collateral  Agent a security
interest therein and in the proceeds  thereof,  which writing shall  incorporate
the  provisions  hereof and shall be in form and substance  satisfactory  to the
Collateral Agent, (G) upon the acquisition after the date hereof by such Grantor
of any motor vehicle or other  Equipment  subject to a  certificate  of title or
ownership (other than a Motor Vehicle or Equipment that is subject to a purchase
money  security  interest),  causing  the  Collateral  Agent to be listed as the
lienholder on such certificate of title or ownership and delivering  evidence of
the same to the  Collateral  Agent in accordance  with the  Securities  Purchase
Agreement;  and (H) taking all actions  required by any earlier  versions of the
Code or by other law, as applicable,  in any relevant Code  jurisdiction,  or by
other law as applicable in any foreign jurisdiction.

      (b)  Location of  Equipment  and  Inventory.  Each  Grantor  will keep the
Equipment  and  Inventory at the  locations  specified  therefor in Section 4(d)
hereof or,  upon not less than thirty  (30) days'  prior  written  notice to the
Collateral  Agent  accompanied by a new Schedule III hereto  indicating each new
location of the Equipment and Inventory,  at such other  locations in the United
States.

      (c)  Condition  of  Equipment.  Each  Grantor  will  maintain or cause the
Equipment  (necessary or useful to its business) to be maintained  and preserved
in good  condition,  repair and working order,  ordinary wear and tear excepted,
and will  forthwith,  or in the case of any loss or damage to any  Equipment  of
such  Guarantor  within a  commercially  reasonable  time  after the  occurrence
thereof,  make  or  cause  to  be  made  all  repairs,  replacements  and  other
improvements   in  connection   therewith  which  are  necessary  or  desirable,
consistent with past practice, or which the Collateral Agent may request to such
end.  Such Grantor will  promptly  furnish to the  Collateral  Agent a statement
describing in reasonable detail any such loss or damage in excess of $250,000 to
any Equipment.

      (d) Taxes,  Etc. Each Grantor agrees to pay promptly when due all property
and other taxes,  assessments and  governmental  charges or levies imposed upon,
and all claims (including claims for labor, materials and supplies) against, the
Equipment  and  Inventory,  except to the extent the  validity  thereof is being
contested in good faith by proper  proceedings  which stay the imposition of any
penalty, fine or Lien resulting from the non-payment thereof and with respect to
which  adequate  reserves  in  accordance  with GAAP have been set aside for the
payment thereof.

      (e) Insurance.

            (i)  Each  Grantor  will,  at its own  expense,  maintain  insurance
(including,  without  limitation,  commercial  general  liability  and  property
insurance) with respect to the Equipment and Inventory in such amounts,  against
such risks, in such form and with responsible and reputable  insurance companies
or associations as is required by any governmental authority having jurisdiction
with  respect  thereto  or as is  otherwise  carried  by  such  Grantor  in  its
reasonable business judgment,  consistent with past practices.  Each such policy
for liability insurance shall provide for all losses to be paid on behalf of the
Collateral Agent and such Grantor as their respective  interests may appear, and
each  policy for  property  damage  insurance  shall  provide  that,  during the
continuance of an Event of Default,  all losses shall be adjusted with, and paid
directly to, the Collateral  Agent.  Each such policy shall in addition (A) name
the  Collateral  Agent as an additional  insured party  thereunder  (without any
representation  or warranty by or obligation upon the Collateral Agent) as their
interests  may appear,  (B) contain an  agreement  by the insurer  that any loss
thereunder  shall be payable to the  Collateral  Agent on its own account during
the continuance of an Event of Default,  notwithstanding any action, inaction or
breach of  representation  or warranty by such  Grantor,  (C) provide that there
shall be no  recourse  against the  Collateral  Agent for payment of premiums or
other amounts with respect thereto, and (D) provide that at least 30 days' prior
written notice of cancellation,  lapse, expiration or other adverse change shall
be given to the  Collateral  Agent by the  insurer.  Such  Grantor  will,  if so
requested by the Collateral  Agent,  deliver to the Collateral Agent original or
duplicate  policies of such insurance and, as often as the Collateral  Agent may
reasonably  request,  a report of a reputable  insurance  broker with respect to
such insurance.

<PAGE>

            (ii)  Reimbursement  under any liability  insurance  maintained by a
Grantor  pursuant to this  Section  5(e) may be paid  directly to the Person who
shall have incurred liability covered by such insurance. In the case of any loss
involving  damage to Equipment or Inventory,  only during the  continuance of an
Event of Default,  any proceeds of insurance maintained by a Grantor pursuant to
this  Section  5(e) shall be paid to the  Collateral  Agent  (except as to which
paragraph (iii) of this Section 5(e) is not applicable),  such Grantor will make
or cause to be made the necessary  repairs to or  replacements of such Equipment
or Inventory,  and any proceeds of insurance maintained by such Grantor pursuant
to this  Section 5(e) shall be paid by the  Collateral  Agent to such Grantor as
reimbursement for the costs of such repairs or replacements.

            (iii)  Only  during  the  continuance  of an Event of  Default,  all
insurance  payments in respect of such  Equipment or Inventory  shall be paid to
the Collateral Agent and applied as specified in Section 7(b) hereof.

      (f) Provisions Concerning the Accounts and the Licenses.

            (i) Each  Grantor  will (A)  give the  Collateral  Agent at least 30
days' prior written  notice of any change in such  Grantor's  name,  identity or
organizational  structure, (B) maintain its jurisdiction of incorporation as set
forth in Section 4(b) hereto,  (C) immediately  notify the Collateral Agent upon
obtaining an  organizational  identification  number, if on the date hereof such
Grantor did not have such  identification  number, and (D) keep adequate records
concerning  the Accounts  and Chattel  Paper and permit  representatives  of the
Collateral  Agent during  normal  business  hours on  reasonable  notice to such
Grantor, to inspect and make abstracts from such Records and Chattel Paper.

            (ii)  Each  Grantor  will,  except  as  otherwise  provided  in this
subsection (f), continue to collect,  at its own expense,  all amounts due or to
become due under the Accounts.  In connection with such  collections  during the
continuance  of an Event of Default,  such Grantor may (and,  at the  Collateral
Agent's  direction,  will) take such  action as such  Grantor or the  Collateral
Agent may deem  necessary or advisable to enforce  collection or  performance of
the Accounts;  provided, however, that the Collateral Agent shall have the right
at any time,  upon the  occurrence  and  during the  continuance  of an Event of
Default,  to notify the account  debtors or obligors  under any  Accounts of the
assignment of such Accounts to the  Collateral  Agent and to direct such account
debtors or obligors to make  payment of all amounts due or to become due to such
Grantor thereunder directly to the Collateral Agent or its designated agent and,
upon such  notification  and at the  expense of such  Grantor  and to the extent
permitted  by law, to enforce  collection  of any such  Accounts  and to adjust,
settle or compromise  the amount or payment  thereof,  in the same manner and to
the same extent as such Grantor might have done. After receipt by a Grantor of a
notice from the Collateral Agent that the Collateral Agent has notified, intends
to notify,  or has enforced or intends to enforce a Grantor's rights against the
account  debtors or obligors under any Accounts as referred to in the proviso to
the  immediately  preceding  sentence,  (A) all amounts and proceeds  (including
Instruments)  received  by such  Grantor  in respect  of the  Accounts  shall be
received in trust for the benefit of the Collateral  Agent  hereunder,  shall be
segregated  from other funds of such Grantor and shall be forthwith paid over to
the  Collateral  Agent in the  same  form as so  received  (with  any  necessary
endorsement)  to be held as cash  collateral and applied as specified in Section
7(b)  hereof,  and (B) such Grantor will not adjust,  settle or  compromise  the
amount or payment of any Account or release  wholly or partly any account debtor
or obligor thereof or allow any credit or discount  thereon.  In addition,  upon
the occurrence and during the continuance of an Event of Default, the Collateral
Agent may (in its sole and absolute  discretion)  direct any or all of the banks
and financial  institutions  with which such Grantor either  maintains a Deposit
Account  or a  lockbox  or  deposits  the  proceeds  of  any  Accounts  to  send
immediately  to the  Collateral  Agent by wire  transfer (to such account as the
Collateral Agent shall specify,  or in such other manner as the Collateral Agent
shall direct) all or a portion of such securities,  cash,  investments and other
items held by such institution. Any such securities, cash, investments and other
items so  received  by the  Collateral  Agent  shall  (in the sole and  absolute
discretion of the  Collateral  Agent) be held as additional  Collateral  for the
Obligations or distributed in accordance with Section 7 hereof.

            (iii) Upon the occurrence  and during the  continuance of any breach
or default under any material  License  referred to in Schedule II hereto by any
party  thereto other than a Grantor,  the Grantor  party thereto will,  promptly
after obtaining  knowledge thereof,  give the Collateral Agent written notice of
the nature and duration  thereof,  specifying what action,  if any, it has taken
and proposes to take with respect  thereto and thereafter  will take  reasonable
steps to protect and  preserve its rights and remedies in respect of such breach
or default, or will obtain or acquire an appropriate substitute License.

            (iv) Each  Grantor  will,  at its expense,  promptly  deliver to the
Collateral Agent a copy of each notice or other communication  received by it by
which any other party to any material  License referred to in Schedule II hereto
purports  to  exercise  any of  its  rights  or  affect  any of its  obligations
thereunder, together with a copy of any reply by such Grantor thereto.

            (v) Each Grantor will  exercise  promptly  and  diligently  each and
every right which it may have under each material  License (other than any right
of  termination)  and will duly  perform and observe in all  respects all of its
obligations  under each  material  License  and will take all action  reasonably
necessary to maintain such  Licenses in full force and effect.  No Grantor will,
without the prior written consent of the Collateral  Agent,  cancel,  terminate,
materially  amend or otherwise  materially  modify in any respect,  or waive any
provision of, any material License referred to in Schedule II hereto.

      (g) Transfers and Other Liens.

            (i) No Grantor will sell, assign (by operation of law or otherwise),
lease,  license,  exchange  or  otherwise  transfer  or  dispose  of  any of the
Collateral,  except (A)  Inventory in the ordinary  course of business,  and (B)
worn-out or obsolete assets not necessary to the business.

            (ii) No Grantor will create,  suffer to exist or grant any Lien upon
or with respect to any Collateral other than a Permitted Lien.

      (h) Intellectual Property.

            (i) If applicable,  each Grantor shall, upon the Collateral  Agent's
written request, duly execute and deliver the applicable Assignment for Security
in the form attached hereto as Exhibit A. Each Grantor (either itself or through
licensees)  will,  and will  cause each  licensee  thereof  to,  take all action
necessary to maintain all of the Intellectual Property in full force and effect,
including,  without limitation,  using the proper statutory notices and markings
and using the Trademarks on each applicable trademark class of goods in order to
so maintain the  Trademarks in full force and free from any claim of abandonment
for non-use,  and such Grantor will not (nor permit any licensee  thereof to) do
any act or knowingly  omit to do any act whereby any  Intellectual  Property may
become invalidated;  provided,  however, that so long as no Event of Default has
occurred and is continuing,  such Grantor shall not have an obligation to use or
to maintain any Intellectual  Property (A) that relates solely to any product or
work, that has been, or is in the process of being,  discontinued,  abandoned or
terminated,  (B) that is being replaced with Intellectual Property substantially
similar to the  Intellectual  Property that may be abandoned or otherwise become
invalid,  so long as the failure to use or maintain such  Intellectual  Property
does  not  materially   adversely   affect  the  validity  of  such  replacement
Intellectual  Property and so long as such replacement  Intellectual Property is
subject to the Lien created by this Agreement or (C) that is  substantially  the
same as another Intellectual Property that is in full force, so long the failure
to use or maintain  such  Intellectual  Property does not  materially  adversely
affect the  validity of such  replacement  Intellectual  Property and so long as
such other  Intellectual  Property is subject to the Lien and security  interest
created by this  Agreement.  Each Grantor  will cause to be taken all  necessary
steps in any proceeding before the United States Patent and Trademark Office and
the United States  Copyright Office or any similar office or agency in any other
country or political  subdivision  thereof to maintain each  registration of the
Intellectual  Property (other than the  Intellectual  Property  described in the
proviso to the immediately preceding sentence),  including,  without limitation,
filing of  renewals,  affidavits  of use,  affidavits  of  incontestability  and
opposition, interference and cancellation proceedings and payment of maintenance
fees,  filing  fees,  taxes  or other  governmental  fees.  If any  Intellectual
Property (other than Intellectual Property described in the proviso to the first
sentence of subsection  (i) of this clause (h)) is  infringed,  misappropriated,
diluted or  otherwise  violated in any material  respect by a third party,  such
Grantor shall (x) upon learning of such infringement, misappropriation, dilution
or other  violation,  promptly notify the Collateral Agent and (y) to the extent
such Grantor shall deem appropriate  under the  circumstances,  promptly sue for
infringement,  misappropriation,  dilution or other  violation,  seek injunctive
relief where appropriate and recover any and all damages for such  infringement,
misappropriation,  dilution or other  violation,  or take such other  actions as
such Grantor  shall deem  appropriate  under the  circumstances  to protect such
Intellectual  Property.  Each Grantor shall furnish to the Collateral Agent from
time to time upon its request  statements and schedules further  identifying and
describing  the  Intellectual  Property and  Licenses and such other  reports in
connection with the  Intellectual  Property and Licenses as the Collateral Agent
may reasonably  request,  all in reasonable  detail and promptly upon request of
the Collateral  Agent,  following  receipt by the  Collateral  Agent of any such
statements,  schedules or reports,  such Grantor shall modify this  Agreement by
amending  Schedule II hereto,  as the case may be, to include  any  Intellectual
Property and License,  as the case may be, which becomes part of the  Collateral
under this  Agreement and shall execute and  authenticate  such documents and do
such acts as shall be  necessary  or, in the judgment of the  Collateral  Agent,
desirable  to subject  such  Intellectual  Property and Licenses to the Lien and
security interest created by this Agreement.  Notwithstanding anything herein to
the contrary,  upon the  occurrence  and during the  continuance  of an Event of
Default,  such  Grantor may not  abandon or  otherwise  permit any  Intellectual
Property to become invalid  without the prior written  consent of the Collateral
Agent, and if any Intellectual Property is infringed,  misappropriated,  diluted
or  otherwise  violated in any material  respect by a third party,  such Grantor
will take such action as the Collateral Agent shall deem  appropriate  under the
circumstances to protect such Intellectual Property.

            (ii) In no event  shall a  Grantor,  either  itself or  through  any
agent, employee,  licensee or designee, file an application for the registration
of any  Trademark  or  Copyright  or the  issuance of any Patent with the United
States Patent and Trademark  Office or the United States  Copyright  Office,  as
applicable,  or in any  similar  office or agency  of the  United  States or any
country or any  political  subdivision  thereof  unless it gives the  Collateral
Agent prompt written notice before or after the occurrence thereof. Upon request
of the Collateral  Agent,  each Grantor shall execute,  authenticate and deliver
any and all assignments,  agreements,  instruments,  documents and papers as the
Collateral  Agent may  reasonably  request to evidence  the  Collateral  Agent's
security  interest  hereunder  in such  Intellectual  Property  and the  General
Intangibles of such Grantor  relating thereto or represented  thereby,  and such
Grantor hereby  appoints the Collateral  Agent its  attorney-in-fact  to execute
and/or authenticate and file all such writings for the foregoing  purposes,  all
acts of such attorney being hereby ratified and confirmed, and such power (being
coupled with an interest) shall be irrevocable  until (A) the earlier of (x) the
indefeasible  payment  in full in  cash  of all of the  Obligations,  or (y) the
indefeasible  conversion of all the Notes in full to Common  Stock,  and (B) the
termination of each of the Transaction Documents.

      (i) Deposit,  Commodities  and  Securities  Accounts.  Upon the Collateral
Agent's  written  request each Grantor shall cause each bank and other financial
institution  with an account  referred  to in  Schedule IV hereto to execute and
deliver  to the  Collateral  Agent a control  agreement,  in form and  substance
reasonably  satisfactory to the Collateral  Agent, duly executed by such Grantor
and such bank or financial institution, or enter into other arrangements in form
and  substance  satisfactory  to the  Collateral  Agent,  pursuant to which such
institution shall irrevocably  agree, inter alia, that (i) it will comply at any
time with the  instructions  originated by the Collateral  Agent to such bank or
financial  institution  directing the disposition of cash,  Commodity Contracts,
securities,  Investment  Property and other items from time to time  credited to
such account,  without further consent of such Grantor,  which  instructions the
Collateral  Agent will not give to such bank or other  financial  institution in
the  absence  of a  continuing  Event  of  Default,  (ii)  all  cash,  Commodity
Contracts,  securities,  Investment  Property  and other  items of such  Grantor
deposited with such institution shall be subject to a perfected,  first priority
security interest in favor of the Collateral Agent,  (iii) any right of set off,
banker's Lien or other similar Lien,  security  interest or encumbrance shall be
fully waived as against the Collateral  Agent,  and (iv) upon receipt of written
notice from the Collateral  Agent during the continuance of an Event of Default,
such bank or financial  institution  shall  immediately  send to the  Collateral
Agent by wire transfer (to such account as the  Collateral  Agent shall specify,
or in such other manner as the Collateral Agent shall direct) all such cash, the
value of any  Commodity  Contracts,  securities,  Investment  Property and other
items held by it.  Without the prior written  consent of the  Collateral  Agent,
such Grantor shall not make or maintain any Deposit Account,  Commodity  Account
or Securities  Account  except for the accounts set forth in Schedule IV hereto.
The provisions of this  paragraph  5(i) shall not apply to (i) Deposit  Accounts
for which the  Collateral  Agent is the  depositary  and (ii)  Deposit  Accounts
specially and  exclusively  used for payroll,  payroll taxes and other  employee
wage  and  benefit  payments  to or for  the  benefit  of a  Grantor's  salaried
employees.

      (j) Motor Vehicles.

            (i) Upon the Collateral Agent's written request,  each Grantor shall
deliver  to the  Collateral  Agent  originals  of the  certificates  of title or
ownership for all motor vehicles owned by it with the Collateral Agent listed as
lienholder, for the benefit of the Buyers.

            (ii)  Each  Grantor  hereby  appoints  the  Collateral  Agent as its
attorney-in-fact, effective the date hereof and terminating upon the termination
of this  Agreement,  for the purpose of (A)  executing on behalf of such Grantor
title or ownership  applications for filing with  appropriate  state agencies to
enable  motor  vehicles  now owned or  hereafter  acquired by such Grantor to be
retitled and the Collateral Agent listed as lienholder thereof,  (B) filing such
applications  with such state  agencies,  and (C) executing such other documents
and  instruments on behalf of, and taking such other action in the name of, such
Grantor as the  Collateral  Agent may deem  necessary or advisable to accomplish
the purposes hereof (including,  without limitation, for the purpose of creating
in favor of the  Collateral  Agent a perfected  Lien on the motor  vehicles  and
exercising  the rights and remedies of the  Collateral  Agent  hereunder).  This
appointment as  attorney-in-fact  is coupled with an interest and is irrevocable
until all of the Obligations are indefeasibly paid in full in cash and after all
Transaction Documents have been terminated.

            (iii) Any certificates of title or ownership  delivered  pursuant to
the terms  hereof shall be  accompanied  by odometer  statements  for each motor
vehicle covered thereby.

            (iv) So long as no Event  of  Default  shall  have  occurred  and be
continuing, upon the request of such Grantor, the Collateral Agent shall execute
and deliver to such Grantor such  instruments  as such Grantor shall  reasonably
request to remove the  notation of the  Collateral  Agent as  lienholder  on any
certificate of title for any motor  vehicle;  provided,  however,  that any such
instruments shall be delivered, and the release effective,  only upon receipt by
the Collateral  Agent of a certificate from such Grantor stating that such motor
vehicle  is to be sold or has  suffered  a casualty  loss  (with  title  thereto
passing to the casualty  insurance  company  therefor in settlement of the claim
for such loss) and the amount that such Grantor will receive as sale proceeds or
insurance proceeds.  Any proceeds of such sale or casualty loss shall be paid to
the Collateral Agent hereunder  immediately  upon receipt,  to be applied to the
Obligations then outstanding.

      (k) Control. Each Grantor hereby agrees to take any or all action that may
be necessary or desirable or that the Collateral  Agent may request in order for
the Collateral Agent to obtain control in accordance with Sections 9-105 - 9-107
of the Code with respect to the following  Collateral:  (i)  Electronic  Chattel
Paper, (ii) Investment Property, and (iii) Letter-of-Credit Rights.

      (l) Subsidiaries. SLI hereby represents and warrants that its wholly-owned
Subsidiary,  SpatiaLight  Technologies,  Inc., is currently  inactive and has no
assets, income or operations. SLI herby agrees that if SpatiaLight Technologies,
Inc. ever becomes active or has assets,  income or operations,  and SLI and each
other Grantor hereby agrees if SLI or such other Grantor shall hereafter  create
or acquire any other Subsidiary, simultaneously therewith SLI or such other such
Grantor shall cause SpatiaLight  Technologies,  Inc. or such other Subsidiary to
become a party to the Guaranty,  in the form attached hereto as Exhibit F to the
Securities Purchase Agreement, as a "Guarantor" thereunder and to this Agreement
as an additional  "Grantor"  hereunder,  and to duly execute and/or deliver such
opinions of counsel and other documents, in form and substance acceptable to the
Collateral Agent, as the Collateral Agent shall reasonably  request with respect
thereto.

      Section 6. Additional Provisions Concerning the Collateral.

      (a) Each Grantor hereby (i) authorizes the Collateral Agent to file one or
more Code financing or continuation statements, and amendments thereto, relating
to the  Collateral and (ii) ratifies such  authorization  to the extent that the
Collateral  Agent has filed any such financing or  continuation  statements,  or
amendments thereto,  prior to the date hereof. A photocopy or other reproduction
of this Agreement or any UCC financing  statement covering the Collateral or any
part thereof shall be sufficient as a UCC financing statement where permitted by
law.

      (b) Each Grantor hereby  irrevocably  appoints the Collateral Agent as its
attorney-in-fact  and proxy,  with full authority in the place and stead of such
Grantor and in the name of such Grantor or  otherwise,  from time to time in the
Collateral Agent's reasonable  discretion,  so long as an Event of Default shall
have  occurred  and is  continuing,  to  take  any  action  and to  execute  any
instrument which the Collateral Agent may reasonably deem necessary or advisable
to  accomplish  the  purposes of this  Agreement  (subject to the rights of such
Grantor under Section 5 hereof),  including,  without limitation,  (i) to obtain
and adjust  insurance  required to be paid to the  Collateral  Agent pursuant to
Section 5(e) hereof, (ii) to ask, demand,  collect, sue for, recover,  compound,
receive and give acquittance and receipts for moneys due and to become due under
or in respect of any  Collateral,  (iii) to  receive,  endorse,  and collect any
drafts or other  instruments,  documents and chattel  paper in  connection  with
clause  (i) or (ii)  above,  (iv) to file  any  claims  or take  any  action  or
institute  any  proceedings  which the  Collateral  Agent may deem  necessary or
desirable  for the  collection  of any  Collateral  or  otherwise to enforce the
rights of the  Collateral  Agent and the Buyers with respect to any  Collateral,
and (v) to execute  assignments,  licenses  and other  documents  to enforce the
rights of the  Collateral  Agent and the Buyers with respect to any  Collateral.
This power is coupled with an interest and is irrevocable the earlier of (i) the
indefeasible  payment  in full in cash  of all of the  Obligations  or (ii)  the
indefeasible  conversion of all the Notes in full to Common Stock,  until all of
the Obligations are indefeasibly paid in full in cash.

      (c) For the purpose of enabling the  Collateral  Agent to exercise  rights
and remedies  hereunder,  at such time as the Collateral Agent shall be lawfully
entitled to exercise such rights and remedies,  and for no other  purpose,  each
Grantor  hereby grants to the Collateral  Agent,  to the extent  assignable,  an
irrevocable,  non-exclusive  license  (exercisable without payment of royalty or
other  compensation to such Grantor) to use,  assign,  license or sublicense any
Intellectual Property now owned or hereafter acquired by such Grantor,  wherever
the same may be located,  including  in such  license  reasonable  access to all
media in which any of the  licensed  items may be  recorded or stored and to all
computer programs used for the compilation or printout thereof.  Notwithstanding
anything contained herein to the contrary,  but subject to the provisions of the
Securities Purchase Agreement that limit the right of such Grantor to dispose of

                                      -16-
<PAGE>

its property and Section 5(h) hereof,  so long as no Event of Default shall have
occurred  and be  continuing,  such Grantor may exploit,  use,  enjoy,  protect,
license, sublicense, assign, sell, dispose of or take other actions with respect
to the  Intellectual  Property  in the  ordinary  course  of  its  business.  In
furtherance of the foregoing, unless an Event of Default shall have occurred and
be continuing, the Collateral Agent shall from time to time, upon the request of
a Grantor, execute and deliver any instruments, certificates or other documents,
in  the  form  so  requested,  which  such  Grantor  shall  have  certified  are
appropriate  (in  such  Grantor's  judgment)  to  allow  it to take  any  action
permitted above (including  relinquishment  of the license provided  pursuant to
this clause (c) as to any Intellectual  Property).  Further, upon the earlier of
(i) the  indefeasible  payment in full in cash of all of the Obligations or (ii)
the  indefeasible  conversion  of all the  Notes in full to  Common  Stock,  the
Collateral Agent (subject to Section 10(e) hereof) shall release and reassign to
such Grantor all of the Collateral  Agent's right,  title and interest in and to
the   Intellectual   Property,   and  the   Licenses,   all  without   recourse,
representation  or warranty  whatsoever.  The  exercise  of rights and  remedies
hereunder by the Collateral  Agent shall not terminate the rights of the holders
of any licenses or sublicenses theretofore granted by such Grantor in accordance
with the second  sentence of this clause (c). Each Grantor  hereby  releases the
Collateral  Agent  from any  claims,  causes of action  and  demands at any time
arising out of or with  respect to any  actions  taken or omitted to be taken by
the  Collateral  Agent under the powers of attorney  granted  herein  other than
actions  taken or omitted  to be taken  through  the  Collateral  Agent's  gross
negligence or willful  misconduct,  as determined by a final  determination of a
court of competent jurisdiction.

      (d) If a Grantor  fails to perform any  agreement  contained  herein,  the
Collateral Agent may itself perform,  or cause performance of, such agreement or
obligation,  in the  name of  such  Grantor  or the  Collateral  Agent,  and the
expenses of the  Collateral  Agent  incurred in  connection  therewith  shall be
payable by such Grantor pursuant to Section 8 hereof and shall be secured by the
Collateral.

      (e) The powers  conferred on the Collateral  Agent hereunder are solely to
protect its interest in the  Collateral and shall not impose any duty upon it to
exercise any such powers.  Except for the safe custody of any  Collateral in its
possession and the accounting for moneys actually received by it hereunder,  the
Collateral  Agent shall have no duty as to any Collateral or as to the taking of
any necessary steps to preserve rights against prior parties or any other rights
pertaining to any Collateral.

      (f) Anything herein to the contrary notwithstanding (i) each Grantor shall
remain  liable  under the  Licenses  and  otherwise  with  respect to any of the
Collateral  to the extent set forth  therein to perform  all of its  obligations
thereunder to the same extent as if this Agreement had not been  executed,  (ii)
the exercise by the Collateral  Agent of any of its rights  hereunder  shall not
release such Grantor from any of its obligations under the Licenses or otherwise
in respect of the Collateral,  and (iii) the Collateral Agent shall not have any
obligation or liability by reason of this  Agreement  under the Licenses or with
respect  to any of the  other  Collateral,  nor shall  the  Collateral  Agent be
obligated to perform any of the obligations or duties of such Grantor thereunder
or to take any  action to  collect or  enforce  any claim for  payment  assigned
hereunder.

      Section 7. Remedies  Upon Event of Default.  If any Event of Default shall
have occurred and be continuing:

      (a) The  Collateral  Agent may exercise in respect of the  Collateral,  in
addition  to any other  rights and  remedies  provided  for herein or  otherwise
available to it, all of the rights and remedies of a secured  party upon default
under the Code (whether or not the Code applies to the affected Collateral), and
also  may (i)  take  absolute  control  of the  Collateral,  including,  without
limitation,  transfer into the  Collateral  Agent's name or into the name of its
nominee or nominees (to the extent the Collateral Agent has not theretofore done
so) and  thereafter  receive,  for the  benefit  of the  Collateral  Agent,  all
payments made thereon,  give all consents,  waivers and ratifications in respect
thereof and  otherwise  act with respect  thereto as though it were the outright
owner thereof, (ii) require each Grantor to, and each Grantor hereby agrees that
it will at its  expense  and upon  request of the  Collateral  Agent  forthwith,
assemble all or part of its respective  Collateral as directed by the Collateral
Agent and make it available to the  Collateral  Agent at a place or places to be
designated  by the  Collateral  Agent  that  is  reasonably  convenient  to both
parties,  and the Collateral  Agent may enter into and occupy any premises owned
or leased by such Grantor where the Collateral or any part thereof is located or
assembled for a reasonable period in order to effectuate the Collateral  Agent's
rights and remedies  hereunder or under law, without  obligation to such Grantor
in respect of such  occupation,  and (iii)  without  notice  except as specified
below and without any  obligation to prepare or process the Collateral for sale,
(A) sell the  Collateral or any part thereof in one or more parcels at public or
private sale, at any of the Collateral  Agent's offices or elsewhere,  for cash,
on credit or for  future  delivery,  and at such  price or prices  and upon such
other terms as the Collateral Agent may deem commercially  reasonable and/or (B)
lease,  license or dispose of the Collateral or any part thereof upon such terms
as the Collateral Agent may deem  commercially  reasonable.  Each Grantor agrees
that, to the extent notice of sale or any other  disposition  of its  respective
Collateral  shall be  required  by law,  at least ten (10) days'  notice to such
Grantor  of the time and place of any public  sale or the time  after  which any
private sale or other  disposition  of its  respective  Collateral is to be made
shall  constitute  reasonable  notification.  The Collateral  Agent shall not be
obligated to make any sale or other disposition of any Collateral  regardless of
notice of sale having been given. The Collateral Agent 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.  Each  Grantor  hereby  waives  any  claims
against the  Collateral  Agent and the Buyers arising by reason of the fact that
the price at which  its  respective  Collateral  may have been sold at a private
sale was less than the price which might have been  obtained at a public sale or
was less than the aggregate  amount of the  Obligations,  even if the Collateral
Agent  accepts the first offer  received and does not offer such  Collateral  to
more than one  offeree,  and  waives all rights  that such  Grantor  may have to
require  that all or any part of such  Collateral  be  marshalled  upon any sale
(public or private) thereof.  Each Grantor hereby acknowledges that (i) any such
sale of its respective  Collateral by the Collateral Agent shall be made without
warranty,  (ii) the Collateral Agent may specifically disclaim any warranties of
title, possession, quiet enjoyment or the like, and (iii) such actions set forth
in  clauses  (i) and (ii)  above  shall  not  adversely  effect  the  commercial
reasonableness of any such sale of Collateral. In addition to the foregoing, (1)
upon written notice to any Grantor from the Collateral Agent, such Grantor shall
cease any use of the Intellectual Property or any trademark, patent or copyright
similar  thereto for any purpose  described in such notice;  (2) the  Collateral
Agent may, at any time and from time to time, upon 10 days' prior notice to such
Grantor,  license,  whether  general,  special or  otherwise,  and whether on an
exclusive or non-exclusive basis, any of the Intellectual  Property,  throughout
the universe for such term or terms, on such conditions,  and in such manner, as
the  Collateral  Agent  shall  in its  sole  discretion  determine;  and (3) the
Collateral Agent may, at any time,  pursuant to the authority granted in Section
6 hereof (such  authority  being  effective  upon the  occurrence and during the
continuance  of an Event of  Default),  execute  and  deliver  on behalf of such
Grantor, one or more instruments of assignment of the Intellectual  Property (or
any application or registration thereof), in form suitable for filing, recording
or registration in any country.

      (b) Any  cash  held by the  Collateral  Agent as  Collateral  and all Cash
Proceeds  received  by  the  Collateral  Agent  in  respect  of any  sale  of or
collection  from, or other  realization  upon, all or any part of the Collateral
may,  in the  reasonable  discretion  of the  Collateral  Agent,  be held by the
Collateral  Agent as  collateral  for,  and/or  then or at any  time  thereafter
applied (after payment of any amounts  payable to the Collateral  Agent pursuant
to Section 8 hereof) in whole or in part by the Collateral Agent against, all or
any part of the  Obligations in such order as the Collateral  Agent shall elect,
consistent with the provisions of the Securities Purchase Agreement. Any surplus
of such cash or Cash Proceeds held by the Collateral  Agent and remaining  after
(i) the indefeasible payment in full in cash of all of the Obligations,  or (ii)
the indefeasible  conversion of all the Notes in full to Common Stock,  shall be
paid over to whomsoever  shall be lawfully  entitled to receive the same or as a
court of competent jurisdiction shall direct.

      (c) In the  event  that the  proceeds  of any  such  sale,  collection  or
realization are  insufficient  to pay all amounts to which the Collateral  Agent
and the  Buyers  are  legally  entitled,  such  each  shall  be  liable  for the
deficiency,  together with interest thereon at the highest rate specified in any
of the  applicable  Transaction  Documents  for  interest  on overdue  principal
thereof or such other rate as shall be fixed by  applicable  law,  together with
the costs of  collection  and the  reasonable  fees,  costs,  expenses and other
client charges of any attorneys employed by the Collateral Agent to collect such
deficiency.

      (d) Each Grantor hereby acknowledges that if the Collateral Agent complies
with any applicable state, provincial, or federal law requirements in connection
with a disposition of the Collateral,  such compliance will not adversely affect
the  commercial   reasonableness  of  any  sale  or  other  disposition  of  the
Collateral.

      (e) The  Collateral  Agent shall not be required to marshal any present or
future collateral  security  (including,  but not limited to, this Agreement and
the Collateral)  for, or other  assurances of payment of, the Obligations or any
of them or to resort to such collateral  security or other assurances of payment
in any particular order, and all of the Collateral  Agent's rights hereunder and
in respect of such collateral  security and other assurances of payment shall be
cumulative and in addition to all other rights,  however existing or arising. To
the extent that each Grantor  lawfully may,  such Grantor  hereby agrees that it
will not invoke any law relating to the  marshalling  of collateral  which might
cause delay in or impede the enforcement of the Collateral  Agent's rights under
this Agreement or under any other  instrument  creating or evidencing any of the
Obligations or under which any of the Obligations is outstanding or by which any
of the Obligations is secured or payment thereof is otherwise  assured,  and, to
the extent that it lawfully  may,  such Grantor  hereby  irrevocably  waives the
benefits of all such laws.

      Section 8. Indemnity and Expenses.

      (a) Each  Grantor  agrees,  jointly  and  severally,  to defend,  protect,
indemnify  and hold the  Collateral  Agent and each of the  Buyers,  jointly and
severally,  harmless  from and  against  any and all  claims,  damages,  losses,
liabilities,  obligations,  penalties,  fees,  costs  and  expenses  (including,
without limitation, reasonable legal fees, costs, expenses, and disbursements of
such Person's  counsel) to the extent that they arise out of or otherwise result
from  this  Agreement  (including,  without  limitation,   enforcement  of  this
Agreement),  except claims,  losses or liabilities resulting solely and directly
from such Person's gross  negligence or willful  misconduct,  as determined by a
final judgment of a court of competent jurisdiction.

      (b) Each Grantor agrees, jointly and severally,  to upon demand pay to the
Collateral  Agent the  amount  of any and all  reasonable  costs and  reasonable
expenses,  including the reasonable fees,  costs,  expenses and disbursements of
counsel  for the  Collateral  Agent and of any  experts  and agents  (including,
without  limitation,  any  collateral  trustee  which  may act as  agent  of the
Collateral  Agent),  which the Collateral Agent may incur in connection with (i)
the preparation, negotiation, execution, delivery, recordation,  administration,
amendment,  waiver or other modification or termination of this Agreement,  (ii)
the custody, preservation, use or operation of, or the sale of, collection from,
or other realization upon, any Collateral,  (iii) the exercise or enforcement of
any of the rights of the Collateral Agent hereunder,  or (iv) the failure by any
Grantor to perform or observe any of the provisions hereof.

      Section 9. Notices, Etc. All notices and other communications provided for
hereunder  shall be in writing and shall be mailed (by certified  mail,  postage
prepaid and return receipt requested),  telecopied or delivered, if to a Grantor
at its  address  specified  below and if to the  Collateral  Agent to it, at its
address  specified  below;  or as to any such Person,  at such other  address as
shall be  designated  by such  Person in a written  notice to such other  Person
complying as to delivery  with the terms of this Section 9. All such notices and
other  communications  shall be effective (a) if sent by certified mail,  return
receipt  requested,  when  received or three days after  deposited in the mails,
whichever  occurs first,  (b) if  telecopied,  when  transmitted  (during normal
business  hours) and  confirmation  is  received,  otherwise,  the day after the
notice was transmitted if confirmation  is received,  or (c) if delivered,  upon
delivery.

      Section 10. Miscellaneous.

      (a) No amendment of any  provision  of this  Agreement  shall be effective
unless it is in writing and signed by each Grantor and the Collateral Agent, and
no waiver of any provision of this Agreement, and no consent to any departure by
a Grantor  therefrom,  shall be effective  unless it is in writing and signed by
the Collateral Agent, and then such waiver or consent shall be effective only in
the specific instance and for the specific purpose for which given.

      (b) No failure on the part of the  Collateral  Agent to  exercise,  and no
delay in exercising,  any right hereunder or under any of the other  Transaction
Documents  shall  operate as a waiver  thereof;  nor shall any single or partial
exercise of any such right preclude any other or further exercise thereof or the
exercise of any other right.  The rights and remedies of the Collateral Agent or
any Buyer provided herein and in the other Transaction  Documents are cumulative
and are in addition to, and not exclusive of, any rights or remedies provided by
law.  The  rights of the  Collateral  Agent or any Buyer  under any of the other
Transaction   Documents  against  any  party  thereto  are  not  conditional  or
contingent on any attempt by such Person to exercise any of its rights under any
of the other  Transaction  Documents  against  such party or  against  any other
Person, including but not limited to, any Grantor.

      (c) Any provision of this Agreement that is prohibited or unenforceable in
any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of
such prohibition or unenforceability without invalidating the remaining portions
hereof or thereof or affecting the validity or  enforceability of such provision
in any other jurisdiction.

      (d) This  Agreement  shall  create a continuing  security  interest in the
Collateral  and  shall  (i)  remain  in full  force  and  effect  until  (x) the
indefeasible  payment in full in cash of the Obligations or (y) the indefeasible
conversion of all the Notes in full to Common Stock, and (ii) be binding on each
Grantor and all other  Persons who become  bound as debtor to this  Agreement in
accordance with Section 9-203(d) of the Code and shall inure,  together with all
rights and remedies of the  Collateral  Agent and the Buyers  hereunder,  to the
benefit of the Collateral  Agent and the Buyers and their  respective  permitted
successors,  transferees and assigns.  Without limiting the generality of clause
(ii) of the immediately  preceding sentence,  without notice to any Grantor, the
Collateral  Agent and the Buyers may assign or otherwise  transfer  their rights
and obligations under this Agreement and any of the other Transaction Documents,
to any other Person and such other Person shall thereupon become vested with all
of the  benefits  in respect  thereof  granted to the  Collateral  Agent and the
Buyers herein or otherwise. Upon any such assignment or transfer, all references
in this  Agreement  to the  Collateral  Agent or any such  Buyer  shall mean the
assignee  of  the  Collateral  Agent  or  such  Buyer.  None  of the  rights  or
obligations  of any Grantor  hereunder may be assigned or otherwise  transferred
without  the  prior  written  consent  of the  Collateral  Agent,  and any  such
assignment or transfer without the consent of the Collateral Agent shall be null
and void.

      (e) Upon the  earlier of (i) the  indefeasible  payment in full in cash of
the Obligations, or (ii) the indefeasible conversion of all the Notes in full to
Common Stock, (A) this Agreement and the security interests created hereby shall
terminate  and all  rights to the  Collateral  shall  revert  to the  respective
Grantor that granted such security interests  hereunder,  and (B) the Collateral
Agent will,  upon such  Grantor's  request and at such  Grantor's  expense,  (1)
return to such  Grantor  such of the  Collateral  as shall not have been sold or
otherwise  disposed of or applied pursuant to the terms hereof, and (2) promptly
execute  and  deliver to such  Grantor  such  documents  as such  Grantor  shall
reasonably request to evidence such termination, all without any representation,
warranty  or  recourse  whatsoever;  provided,  however,  that if (x)  after the
Additional  Investment  Rights have either been exercised in full or terminated,
the  aggregate  unpaid  principal  balance of the Notes shall,  at any time,  be
indefeasibly  reduced  to less  than  $2,000,000  (after  giving  effect  to any
indefeasible  repayments and redemptions  thereof,  and any indefeasible partial
conversions  thereof to shares of Common Stock),  and (y) the  Collateral  Agent
receives  any  Grantor's  written  request  therefor  91 or more days after such
indefeasible  reduction,  then, so long as no Event of Default (and no any event
or circumstance that, with the passage of time or the giving of notice, or both,
would become an Event of Default)  shall have  occurred and then be  continuing,
the Collateral  Agent shall terminate this Agreement and the security  interests
created hereby,  and all rights to the Collateral shall revert to the respective
Grantor that granted such  security  interests  hereunder as provided in clauses
(A) and (B) hereof.

such service to become effective 10 days after such mailing.

      (j) Nothing  contained  herein  shall  affect the right of the  Collateral
Agent to serve  process in any other manner  permitted by law or commence  legal
proceedings  or  otherwise  proceed  against any Grantor or any property of such
Grantor in any other jurisdiction.

by the Purchase Agreement (each, an "Indemnitee"), from and against any and all
actions, causes of action, suits, claims, losses, costs, penalties, fees,
liabilities, damages and expenses (irrespective of whether any such Indemnitee
is a party to the action for which indemnification hereunder is sought), and
including, without limitation, reasonable attorneys' fees and disbursements
(collectively, the "Indemnified Liabilities"), incurred by any Indemnitee as a
result of, or arising out of, or otherwise relating to, the breach of any
representation, warranty, covenant or agreement made by SLK in this agreement.
To the extent that the foregoing undertaking by SLK may be unenforceable for any
reason, SLK shall make the maximum contribution to the payment and satisfaction
of each of the Indemnified Liabilities that is permissible under applicable law.

      This agreement shall (a) be binding on SLK and its respective successors

other Person, and such other Person shall thereupon become vested with all of
the benefits in respect thereof granted to the Buyers herein or otherwise.

      To the extent that SLK has or hereafter may acquire any immunity from
jurisdiction of any court or from any legal process (whether through service or
notice, attachment prior to judgment, attachment in aid of execution or
otherwise) with respect to itself or its property, SLK hereby irrevocably waives
such immunity in respect of its obligations under this agreement.

      This agreement shall be governed by, construed and interpreted in
accordance with the laws of the State of New York, except as required by
mandatory provisions of applicable law. Any legal action, suit or proceeding
with respect to this agreement may be brought in the courts of the State of New
York in the County of New York or the United States of America for the Southern
District of New York, and appellate courts thereof, and, by execution and
delivery of this agreement, SLK hereby accepts for itself and in respect of its
property, generally and unconditionally, the jurisdiction of the aforesaid
courts. SLK hereby expressly and irrevocably waives, to the fullest extent
permitted by law, any objection, including, without limitation, any objection to
the laying of venue or based on the grounds of forum non conveniens, which it
may now or hereafter have to the bringing of any such action, suit or proceeding
in such respective jurisdictions and consents to the granting of such legal or
equitable relief as is deemed appropriate by the court.

                                       2
<PAGE>

this agreement, or any course of conduct, course of dealing, verbal or written
statement or other action of the parties hereto.
