"Obligation"), Pledgor hereby conditionally assigns to TTR, and grants TTR a
security interest in (i) all shares of common stock, par value $0.001 (the

exercise of options held by Pledgor or hereinafter issued to purchase or acquire
Common Stock (all of the foregoing property and any part thereof being
hereinafter referred to as, "Collateral")

      2. Pledgor hereby warrants and represents that except for the security
interest granted hereby and issuer restrictions on the Collateral, Pledgor is
the sole owner of the Collateral free from any adverse lien, security interest,
encumbrance and restriction on transfer and the Collateral is in all respects
what it purports to be and that debtor will defend the Collateral against all
claims and demands of all persons at any time claiming the same or any interest
therein and that no financing statement covering any of Collateral or any
proceeds thereof is on file in any public office and that TTR may without notice
or signature of Pledgor file any financing statement, amendments or
continuations, naming Pledgor or Borrower as debtor and TTR as secured party and
that alternatively or additionally, at the request of TTR, Pledgor will join
with TTR in executing and filing one or more, financing statements, amendments
or continuations, in form satisfactory to TTR. In order to perfect, maintain or
protect its security interest in Collateral, TTR may deliver a copy of this
Agreement to any person or entity.

interest or encumbrance and will not pledge, assign, grant a security interest
or attempt to transfer any of the Collateral or any interest in it. Pledgor will
not use the collateral in violation of any law, statute or ordinance and shall
give TTR prompt notice of any lien attachment or security interest charged
against the Collateral. TTR at its option may pay or cause the discharge of any
charges against the Collateral and may take any other action necessary to
preserve the Collateral. Pledgor shall do, execute and deliver all additional
acts, instruments as TTR may require to more completely assure TTR of its rights
hereunder.

      4. Pledgor shall be in default under this Agreement upon the happening of
any of the following events or conditions ("Default"):

      (i) Default in the payment or performance of any obligation, covenant or
liability contained or referred to in the Agreement or herein;

      (ii) Any warranty, representation or statement made or furnished to TTR by
or on behalf of Pledgor proves to have been false in any material respect when
made or furnished;




      (iii) Loss, theft, substantial damage, destruction, sale or encumbrance to
or of any of the Collateral, or the making of any levy, seizure or attachment
thereof or thereon;

      (iv) Dissolution, termination of existence, insolvency, business failure,
appointment of a receiver of any part of the property, assignment for the
benefit of creditors, or the commencement of any proceeding under any bankruptcy
or insolvency laws by or against, Borrower or Pledgor or any guarantor or surety
for Borrower or Pledgor.

secured hereby absolutely and immediately due and payable and TTR shall have the
remedies of a secured party under the Uniform Commercial Code as adopted and
applicable in New York State including without limitation the following:

      (i) Pledgor hereby irrevocably appoints TTR its true and lawful agent and,
in connection with Collateral which are shares of stock, its proxy with power of
substitution for Pledgor, to act in the event of default in Pledor's or TTR's
name as fully and completely as though TTR were the absolute owner of the
Collateral for all purposes. TTR may exercise all of Pledgor's rights pertaining
to the Collateral including without limitation, the exercise of all corporate or
voting rights as to Collateral that are shares, the rights of collection,
enforcement, conversion and exchange and the right to sell, assign, pledge,
transfer or convey the Collateral as well as the right to commence, prosecute or
settle any legal action respecting the Collateral.

      (ii) Following a Default,without notice or demand, Pledgor will assemble
and deliver forthwith to TTR, the Collateral or any proceeds therefrom.

      6. All of TTR's rights and remedies shall be cumulative and any failure of
TTR to exercise any right hereunder shall not be construed as a waiver of the
right to exercise the same or any other right at any time, and from time to
time, thereafter.

      7. Pledgor will pay to TTR promptly upon demand all reasonable costs and
expenses, including attorney's fees, that may be incurred by TTR in attempting
to enforcing its rights under this Agreement or in establishing, maintaining or
defending its rights to do any of the foregoing.

      8. TTR may assign this Agreement or any of its rights and powers
hereunder, with all or any of the obligations hereby guaranteed.

the laws of the State of New York applicable to agreements made and performed
wholly therein. In connection with any dispute which may arise under this
Pledge, Pledgor hereby irrevocably submits and consents and waives any objection

County or of the United States District Court Southern District of New York, or
at TTR's option, to the courts of any jurisdiction in which or any of Pledgor's
assets may be located, and waives any objection to the laying of venue in any
such court. Pledgor admits that any such dispute may be resolved at least as
conveniently in such a court as in any other court and will not seek dismissal
or change of venue on the grounds that resolution of such a dispute in such a
forum is not convenient or in the interest of justice. Pledgor shall not seek a
jury trial in any action based upon or arising out of this Agreement or any
related document or agreement. Pledgor will not seek to consolidate any such
action with any other action in which trial by jury has not been waived.

sought, with an authorized officer of TTR signing if it must sign; the waiver by
