     3. Events of Default.  An event of default  under this  Agreement  shall be
deemed to exist upon the  occurrence  of any of the  following  event (each such
event being herein called an "Event of Default"):  (i) an Event of Default under
the Convertible  Note or default under or breach of the Guarantee;  (ii) failure
of Pledgor  punctually and fully to perform,  observe,  discharge or comply with

conservator or other  custodian for any of its property,  or if Pledgor  becomes

or if any  reorganization or arrangement  proceeding is instituted by or against
Pledgor for the settlement, readjustment, composition or extension of any of its
debts  upon any terms,  or if any action or  petition  is  otherwise  brought by
Pledgor seeking similar relief or alleging that it is insolvent or unable to pay
its debts as they mature.

     4. Delivery of Pledged Collateral.  Upon execution and delivery hereof, all
certificates or instruments  representing  or evidencing the Pledged  Collateral
shall be  delivered  by  Pledgor to Pledgee  and shall be in  suitable  form for
transfer  by  delivery,  or  shall  be  accompanied  by  duly  executed  undated
instruments  of  transfer  or  assignment  in blank,  all in form and  substance
satisfactory to Pledgee. In addition,  in the event that during the term of this
Agreement  Pledgor  shall have become  entitled to receive  with  respect to the
Pledged  Collateral  any  certificate,  option  or  rights  (including,  without
limitation,   in   connection   with  a  dividend,   distribution   of  capital,
reclassification,  reorganization,  merger or other  exchange of units),  or any
liquidating  distributions,  Pledgor also agrees to immediately deliver the same

     6. Additional Remedies on Default.  Upon occurrence of an Event of Default,
Pledgee, (i) without demand of performance or other demand or notice of any kind
may forthwith declare any or all of the Guaranteed Obligations to be immediately
due and payable and  foreclose  or  otherwise  enforce  the  Pledgee's  security
interest in the Pledged  Collateral  in any manner  permitted by law or provided
for in this Agreement,  including,  without limitation,  to register the Pledged
Collateral  in its own name or its  nominee  and,  subject  to  compliance  with
applicable state and U.S. Federal securities laws and rules, sell, assign,  give

in whole or part, at public or private sale or sales,  which sale or sales shall
be held in a  commercially
<PAGE>
reasonable  manner within the meaning of the Uniform  Commercial  Code in effect
under the laws of the State of New  Jersey,  upon such terms and  conditions  as
Pledgee  may deem  advisable  and at such  prices at it may deem best,  with the
right of Pledgee  upon any such sale or sales to purchase  the whole or any part
of the Pledged Collateral, free of any right or equity of redemption in Pledgor,
which right or equity is  expressly  waived or  released,  (ii) may recover from
Pledgor  all costs  and  expenses,  including,  without  limitation,  reasonable
attorney's  fees,  incurred or paid by Pledgee in  exercising  or enforcing  any
right, power, or remedy with respect to any or all of the Collateral provided to
it by this  Agreement  or by  applicable  law;  and (iii)  shall be  entitled to
immediately exercise all voting rights and other consensual rights pertaining to
the Pledged Shares.

     All monies and other proceeds received by Pledgee upon any collection, sale
or other disposition of any Collateral, together with all other monies and other
proceeds received by Pledgee hereunder, shall be applied in the following order:
(i) to the payment of the reasonable costs and expenses of such sale, collection
or other disposition which may have been incurred by Pledgee,  including without
limitation  attorney's  fees as  provided  in  clause  (b)  above  and all other
reasonable  expenses,  liabilities  and advances  made or incurred by Pledgee in
connection  therewith;  (ii) to the payment of all other Guaranteed  Obligations
then due in such order as Pledgee may elect;  and (iii) after payment in full of
all  Guaranteed  Obligations  then due,  any surplus  then  remaining  from such
proceeds  shall be paid to Pledgor.  Pledgor  shall remain liable to Pledgee for
any deficiency owing on the Guaranteed  Obligations after the application of the
proceeds of the Pledged Collateral as provided above.

     The  remedies  provided  herein  in favor of  Pledgee  shall  not be deemed
exclusive,  but  shall be  cumulative,  and  shall be in  addition  to all other
remedies in favor of Pledgee existing at law or in equity.

     7.  Representations and Covenants of Pledgor.  Until the fulfillment of the
Guaranteed  Obligations,  Pledgor  represents,  warrants  and agrees as follows:
Pledgor has the legal right and all requisite  corporate power and authority and
approvals  required to execute and deliver this  Agreement  and to perform fully
its obligations hereunder. This Agreement and the other documents and agreements
being  delivered in  connection  herewith to which  Pledgor is a party have been
duly  authorized by all necessary  corporate  action and have been duly executed
and  delivered by Pledgor and  (assuming  the due  authorization,  execution and
delivery hereof by Pledgee) are valid and binding obligations of Pledgor, as the
case may be, enforceable against it in accordance with its terms. The execution,
delivery and  performance  by Pledgor of this  Agreement in accordance  with its
terms (i) are not and will not be  inconsistent  with  Pledgor's  Certificate of
Incorporation  (as  amended)  or  Pledgor's  By  laws,  or  the  Certificate  of
Incorporation  (as amended) or By laws of GSV,  (ii) do not and will not require
the approval or consent of any governmental  body or any other person;  (iii) do
not and will not  conflict  with or result in any breach or  violation of any of
the terms and  conditions  of, or constitute (or with notice or lapse of time or
both would constitute) a default under any law or order of any governmental body
applicable  to Pledgor,  or any contract to which Pledgor is a party or by or to
which  Pledgor or any of its  properties  is bound or subject;  or (iv) will not
result in the creation of any lien on any of the properties of Pledgor. Promptly
after the  execution of this  Agreement,  the Pledgor  shall take or cause to be
taken all actions,  and bear all costs,  necessary to file any and all financing
statements and other similar  documents as may be required under  applicable law
in order to  perfect  or  maintain  the  perfection  of the  Pledgee's  security
interest in the Pledged  Collateral.  The  Pledged  Collateral  owned by Pledgor
shall at all times be free and clear of all claims,  mortgages,  pledges, liens,
encumbrances  and security  interests of every nature  whatsoever  created by or
arising  through  it,  except  for the  security  interest  granted  to  Pledgee
hereunder.

     8. Further  Assurances.  Pledgor hereby  represents and warrants that it is
the owner and holder of the  Pledged  Collateral,  free and clear of any claims,
mortgages,  pledges, liens,  encumbrances and security interests of every nature
whatsoever.  The Pledged Shares are duly authorized,  validly issued, fully paid
and non-assessable shares of Series B Preferred Stock of GSV. Pledgor will, from
time to time, at Pledgor's expense, and upon Pledgee's request, promptly execute
and deliver all further  instruments  and documents and take all further  action
that may be necessary or desirable,  or that Pledgee may reasonably  request, in
order to perfect and protect any  security  interest  granted or purported to be
granted  hereby,  to enable  Pledgee  to  exercise  and  enforce  the rights and
remedies of Pledgee  hereunder with respect to any of the Pledged  Collateral or
to carry out the  provisions and purposes  hereof.  Pledgor shall permit Pledgee
(or any person designated by it) from time to time to inspect the Collateral and
to  inspect,  audit and make  copies of or  extracts  from all books and records
maintained by or on behalf of Pledgor pertaining to the Pledged  Collateral.  So
long as any of the  Guaranteed  Obligations  shall be  outstanding,  the Pledgor
shall not, without the express prior written consent of Pledgee,  sell,  assign,
exchange,  pledge or otherwise transfer,  encumber, or grant any option, warrant
or other right to purchase any Pledged Collateral which is pledged hereunder, or
consent to any amendment to the certificate of  incorporation  or certificate of
designations,  preferences  and rights  pertaining  to the  Pledged  Shares that
adversely  affects the rights of the holders of the Pledged  Shares.  In case of
any adverse claims in respect to the Pledged Collateral or any portions thereof,
arising out of any act done or suffered by  Pledgor,  the Pledgor  promises  and
agrees to hold  harmless and to  indemnify  Pledgee from and against any losses,
liabilities,  damages,  expenses, costs, and


                                      -2-
<PAGE>
reasonable  attorneys'  fees  incurred  in or about  defending,  protecting,  or
prosecuting the security interests hereby created.

     9. Voting Rights Prior to Default.  Prior to the  occurrence of an Event of
Default in the  performance  of the  Guaranteed  Obligations,  Pledgor  shall be
entitled to exercise all voting rights and other consensual rights pertaining to
the Pledged Shares.

     10. Successors and Assigns.  This Agreement shall be binding upon and inure
to the benefit of the parties hereto and their  respective  successors,  assigns
and transferees.  All obligations of the Pledgor hereunder shall be binding upon
its legal  representatives,  successors,  and assigns.  This  Agreement  and all
security interests and other liens granted or conveyed hereunder shall remain in
full force and effect and shall be irrevocable  until such time as no Guaranteed
Obligations  are  outstanding.  At such time,  any  certificates  or instruments
representing the Pledged  Collateral which are in Pledgee's  possession shall be
delivered by Pledgee to Pledgor.

     11.  Amendments.  This Agreement may not be modified,  amended,  altered or
supplemented, and no waiver or consent may be granted hereunder, except upon the
