      A. The Secured Party and Vitrotech Corporation, a Nevada corporation (the
"BORROWER") have entered into a Note and Warrant Purchase Agreement, dated as of
the date hereof (the "PURCHASE AGREEMENT"), pursuant to which the Secured Party
has agreed to loan up to $3,000,000 to the Borrower on the terms and subject to
the conditions of the Purchase Agreement ("LOAN"). On the terms and subject to
the conditions of the Purchase Agreement, the Loan advances will be evidenced by
one or more secured, convertible promissory notes made by the Borrower in favor
of the Secured Party (the "NOTES") as more fully set forth in the Purchase
Agreement.

      B. The Borrower owns 100% of the issued and outstanding capital stock of
the Debtor and substantially all of the Loan proceeds will be contributed to, or
otherwise used for the sole and exclusive benefit of the Debtor.

      C. It is a condition precedent to the Secured Party's making any Loan (or
otherwise extending credit) to the Borrower that the Debtor execute and deliver
to the Secured Party (i) a guaranty of the obligations of the Borrower under the
Purchase Agreement and related Notes (the "GUARANTY") and (ii) a security
agreement in substantially the form hereof.

      D. The Debtor wishes to grant a security interest in favor of the Secured
Party as herein provided and the Debtor and agrees that the Loan (or any part
thereof) made by the Secured Party to the Debtor constitutes reasonably
equivalent value to the Debtor in consideration for the execution of the
Guaranty and this security agreement in light thereof.

      NOW, THEREFORE, in consideration of the promises contained herein and for
other good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, the parties hereto agree as follows:

Guaranty or this Agreement, and the term "EVENT OF DEFAULT," as used herein,
means the failure of the Debtor to pay or perform any of the Obligations as and
when due to be paid or performed under the terms of the Guaranty.

      2. Grant of Security Interest. The Debtor hereby grants to the Secured

            10.2 Insurance Proceeds. The proceeds of any casualty insurance in
respect of any casualty loss of any of the Collateral shall, subject to the
rights, if any, of other parties with an interest having priority in the

or destroyed, and (ii) in all other circumstances, be held by the Secured Party

with the foregoing insurance provision.

      11. Collateral Protection Expenses; Preservation of Collateral.

discretion, if the Debtor fails to do so, the Secured Party may discharge taxes
and other encumbrances at any time levied or placed on any of the Collateral,
maintain any of the Collateral, make repairs thereto and pay any necessary
filing fees or insurance premiums. The Debtor agrees to reimburse the Secured
Party on demand for all expenditures so made. The Secured Party shall have no

thereof be construed as the waiver or cure of any Default or Event of Default.

            11.2 Secured Party's Obligations and Duties. Anything herein to the
contrary notwithstanding, the Debtor shall remain obligated and liable under
each contract or agreement comprised in the Collateral to be observed or
performed by the Debtor thereunder. The Secured Party shall not have any
obligation or liability under any such contract or agreement by reason of or
arising out of this Agreement or the receipt by the Secured Party of any payment
relating to any of the Collateral, nor shall the Secured Party be obligated in
any manner to perform any of the obligations of the Debtor under or pursuant to
any such contract or agreement, to make inquiry as to the nature or sufficiency
of any payment received by the Secured Party in respect of the Collateral or as
to the sufficiency of any performance by any party under any such contract or


                                       7
<PAGE>

agreement, to present or file any claim, to take any action to enforce any
performance or to collect the payment of any amounts which may have been
assigned to the Secured Party or to which the Secured Party may be entitled at
any time or times. The Secured Party's sole duty with respect to the custody,
safe keeping and physical preservation of the Collateral in its possession,
under Section 9-207 of the Uniform Commercial Code of the State or otherwise,
shall be to deal with such Collateral in the same manner as the Secured Party

      12. Securities and Deposits. The Secured Party may at any time, at its
option, transfer to itself or any nominee any securities constituting
Collateral, receive any income thereon and hold such income as additional
Collateral or apply it to the Obligations. Whether or not any Obligations are
due, the Secured Party may demand, sue for, collect, or make any settlement or
compromise which it deems desirable with respect to the Collateral. Regardless
of the adequacy of Collateral or any other security for the Obligations, any
deposits or other sums at any time credited by or due from the Secured Party to
the Debtor may at any time be applied to or set off against any of the
Obligations.

      13. Notification to Account Debtors and Other Persons Obligated on
Collateral. The Debtor shall, at the request and option of the Secured Party,
notify account Debtors and other persons obligated on any of the Collateral of
the security interest of the Secured Party in any account, chattel paper,
general intangible, instrument or other Collateral and that payment thereof is
to be made directly to the Secured Party or to any financial institution
designated by the Secured Party as the Secured Party's agent therefor, and the
Secured Party may itself, without notice to or demand upon the Debtor, so notify
account Debtors and other persons obligated on Collateral. After the making of
such a request or the giving of any such notification, the Debtor shall hold any
proceeds of collection of accounts, chattel paper, general intangibles,
instruments and other Collateral received by the Debtor as trustee for the
Secured Party without commingling the same with other funds of the Debtor and
shall turn the same over to the Secured Party in the identical form received,
together with any necessary endorsements or assignments. The Secured Party shall
apply the proceeds of collection of accounts, chattel paper, general
intangibles, instruments and other Collateral received by the Secured Party to
the Obligations, such proceeds to be immediately credited after final payment in
cash or other immediately available funds of the items giving rise to them.

      14. Power of Attorney.

            14.1 Appointment and Powers of Secured Party. The Debtor hereby
irrevocably constitutes and appoints the Secured Party and any officer or agent
thereof, with full power of substitution, as its true and lawful
attorneys-in-fact with full irrevocable power and authority in the place and
stead of the Debtor or in the Secured Party's own name, for the purpose of
carrying out the terms of this Agreement, to take any and all appropriate action
and to execute any and all documents and instruments that may be necessary or
useful to accomplish the purposes of this Agreement and, without limiting the
generality of the foregoing, hereby gives said attorneys the power and right, on
behalf of the Debtor, without notice to or assent by the Debtor, to do the
following:

            (a) upon the occurrence and during the continuance of an Event of
Default, generally to sell, transfer, pledge, make any agreement with respect to
or otherwise dispose of or deal with any of the Collateral in such manner as is
consistent with the Uniform Commercial Code of the State and as fully and
completely as though the Secured Party were the absolute owner thereof for all
purposes, and to do, at the Debtor's expense, at any time, or from time to time,
all acts and things which the Secured Party deems necessary or useful to
protect, preserve or realize upon the Collateral and the Secured Party's
security interest therein, in order to effect the intent of this Agreement, all
at least as fully and effectively as the Debtor might do, including, without
limitation, (i) the filing and prosecuting of registration and transfer
applications with the appropriate federal, state, local or other agencies or
authorities with respect to trademarks, copyrights and patentable inventions and
processes, (ii) upon written notice to the Debtor, the exercise of voting rights
with respect to voting securities, which rights may be exercised, if the Secured

connection with any sale or other disposition of any Collateral, of the
endorsements, assignments or other instruments of conveyance or transfer with

substitution for a financing statement, as the Secured Party may deem
appropriate and to execute in the Debtor's name such financing statements and
amendments thereto and continuation statements which may require the Debtor's
signature.

            14.2 Ratification by Debtor. To the extent permitted by law, the
Debtor hereby ratifies all that said attorneys shall lawfully do or cause to be
done by virtue hereof. This power of attorney is a power coupled with an
interest and is irrevocable.

            14.3 No Duty on Secured Party. The powers conferred on the Secured
Party hereunder are solely to protect its interests in the Collateral and shall
not impose any duty upon it to exercise any such powers. The Secured Party shall
be accountable only for the amounts that it actually receives as a result of the
exercise of such powers, and neither it nor any of its officers, directors,
employees or agents shall be responsible to the Debtor for any act or failure to
act, except for the Secured Party's own gross negligence or willful misconduct.

      15. Rights and Remedies. If an Event of Default shall have occurred and be
continuing, the Secured Party, without any other notice to or demand upon the
Debtor have in any jurisdiction in which enforcement hereof is sought, in
addition to all other rights and remedies, the rights and remedies of a secured
party under the Uniform Commercial Code of the State and any additional rights
and remedies which may be provided to a secured party in any jurisdiction in
which Collateral is located, including, without limitation, the right to take
possession of the Collateral, and for that purpose the Secured Party may, so far
as the Debtor can give authority therefor, enter upon any premises on which the
Collateral may be situated and remove the same therefrom. The Secured Party may
in its discretion require the Debtor to assemble all or any part of the
Collateral at such location or locations within the jurisdiction(s) of the
Debtor's principal office(s) or at such other locations as the Secured Party may
reasonably designate. Unless the Collateral is perishable or threatens to
decline speedily in value or is of a type customarily sold on a recognized
market, the Secured Party shall give to the Debtor at least five Business Days
prior written notice of the time

and place of any public sale of Collateral or of the time after which any
private sale or any other intended disposition is to be made. The Debtor hereby
acknowledges that five Business Days prior written notice of such sale or sales
shall be reasonable notice. In addition, the Debtor waives any and all rights
that it may have to a judicial hearing in advance of the enforcement of any of
the Secured Party's rights and remedies hereunder, including, without
limitation, its right following an Event of Default to take immediate possession
of the Collateral and to exercise its rights and remedies with respect thereto.

      16. Standards for Exercising Rights and Remedies. To the extent that
applicable law imposes duties on the Secured Party to exercise remedies in a
commercially reasonable manner, the Debtor acknowledges and agrees that it is
not commercially unreasonable for the Secured Party (a) to fail to incur
expenses reasonably deemed significant by the Secured Party to prepare
Collateral for disposition or otherwise to fail to complete raw material or work
in process into finished goods or other finished products for disposition, (b)
to fail to obtain third party consents for access to Collateral to be disposed
of, or to obtain or, if not required by other law, to fail to obtain
governmental or third party consents for the collection or disposition of
Collateral to be collected or disposed of, (c) to fail to exercise collection
remedies against account Debtors or other persons obligated on Collateral or to
fail to remove liens or encumbrances on or any adverse claims against
Collateral, (d) to exercise collection remedies against account Debtors and
other persons obligated on Collateral directly or through the use of collection
agencies and other collection specialists, (e) to advertise dispositions of
Collateral through publications or media of general circulation, whether or not
the Collateral is of a specialized nature, (f) to contact other persons, whether
or not in the same business as the Debtor, for expressions of interest in
acquiring all or any portion of the Collateral, (g) to hire one or more
professional auctioneers to assist in the disposition of Collateral, whether or
not the collateral is of a specialized nature, (h) to dispose of Collateral by
utilizing Internet sites that provide for the auction of assets of the types
included in the Collateral or that have the reasonable capability of doing so,
or that match buyers and sellers of assets, (i) to dispose of assets in
wholesale rather than retail markets, (j) to disclaim disposition warranties,
(k) to purchase insurance or credit enhancements to insure the Secured Party
against risks of loss, collection or disposition of Collateral or to provide to
the Secured Party a guaranteed return from the collection or disposition of
Collateral, or (l) to the extent deemed appropriate by the Secured Party, to
obtain the services of other brokers, investment bankers, consultants and other
professionals to assist the Secured Party in the collection or disposition of
any of the Collateral. The Debtor acknowledges that the purpose of this Section
16 is to provide non-exhaustive indications of what actions or omissions by the
Secured Party would fulfill the Secured Party's duties under the Uniform
Commercial Code or other law of the State or any other relevant jurisdiction in
the Secured Party's exercise of remedies against the Collateral and that other
actions or omissions by the Secured Party shall not be deemed to fail to fulfill
such duties solely on account of not being indicated in this Section 16. Without
limitation upon the foregoing, nothing contained in this Section 16 shall be
construed to grant any rights to the Debtor or to impose any duties on the
Secured Party that would not have been granted or imposed by this Agreement or
by applicable law in the absence of this Section 16.

      17. Notices. All notices required or permitted by this Agreement shall be
in writing or by telex or facsimile transmission and shall be deemed to have
been duly given (i) on the date of service if delivered in person or by telex or
facsimile transmission (with the telex or facsimile confirmation of transmission
receipt acting as confirmation of service when sent and provided

      18. No Waiver by Secured Party, etc. The Secured Party shall not be deemed
to have waived any of its rights or remedies in respect of the Obligations or
the Collateral unless such waiver shall be in writing and signed by the Secured
Party. No delay or omission on the part of the Secured Party in exercising any
right or remedy shall operate as a waiver of such right or remedy or any other
right or remedy. A waiver on any one occasion shall not be construed as a bar to
or waiver of any right or remedy on any future occasion. All rights and remedies
of the Secured Party with respect to the Obligations or the Collateral, whether
evidenced hereby or by any other instrument or papers, shall be cumulative and
may be exercised singularly, alternatively, successively or concurrently at such
time or at such times as the Secured Party deems expedient.

      19. Suretyship Waivers by Debtor. The Debtor waives demand, notice,
protest, notice of acceptance of this Agreement, notice of loans made, credit
extended, Collateral received or delivered or other action taken in reliance
hereon and all other demands and notices of any description. With respect to
both the Obligations and the Collateral, the Debtor assents to any extension or
postponement of the time of payment or any other indulgence, to any
substitution, exchange or release of or failure to perfect any security interest
in any Collateral, to the addition or release of any party or person primarily
or secondarily liable, to the acceptance of partial payment thereon and the
settlement, compromising or adjusting of any thereof, all in such manner and at
such time or times as the Secured Party may deem advisable. The Secured Party
shall have no duty as to the collection or protection of the Collateral or any
income therefrom, the preservation of rights against prior parties, or the
preservation of any rights pertaining thereto beyond the safe custody thereof as
set forth in Section 11.2. The Debtor further waives any and all other
suretyship defenses.

      20. Marshalling. The Secured Party shall not be required to marshal any
present or future collateral security (including but not limited to the
Collateral) for, or other assurances of payment of, the Obligations or any of
them or to resort to such collateral security or other


                                       11
<PAGE>

assurances of payment in any particular order, and all of its rights and
remedies hereunder and in respect of such collateral security and other
assurances of payment shall be cumulative and in addition to all other rights
and remedies, however existing or arising. To the extent that it lawfully may,
the Debtor 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 Secured Party's rights and remedies 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, the Debtor hereby irrevocably waives the benefits of all such
laws.

      21. Proceeds of Dispositions; Expenses. The Debtor shall pay to the
Secured Party on demand any and all expenses, including reasonable attorneys'
fees and disbursements, incurred or paid by the Secured Party in protecting,
preserving or enforcing the Secured Party's rights and remedies under or in
respect of any of the Obligations or any of the Collateral. After deducting all
of said expenses, the residue of any proceeds of collection or sale or other
disposition of the Collateral shall, to the extent actually received in cash, be
applied to the payment of the Obligations in such order or preference as the
Secured Party may determine, proper allowance and provision being made for any
Obligations not then due. Upon the final payment and satisfaction in full of all
of the Obligations and after making any payments required by Sections
9608(a)(1)(C) or 9615(a)(3) of the Uniform Commercial Code of the State, any
excess shall be returned to the Debtor. In the absence of final payment and
satisfaction in full of all of the Obligations, the Debtor shall remain liable
for any deficiency.

      22. Overdue Amounts. Until paid, all amounts due and payable by the Debtor
hereunder shall be a debt secured by the Collateral and shall bear, whether
before or after judgment, interest at the rate of interest for overdue principal
set forth in the Initial Note (as that term is defined in the Purchase
Agreement) .

      23. Governing Law; Consent to Jurisdiction. THIS AGREEMENT SHALL BE
GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF
CALIFORNIA. The Debtor agrees that any action or claim arising out of, or any
dispute in connection with, this Agreement, any rights, remedies, obligations,
or duties hereunder, or the performance or enforcement hereof or thereof, may be
brought in the courts of the State or any federal court sitting therein and
consents to the non-exclusive jurisdiction of such court and to service of
process in any such suit being made upon the Debtor by mail at the address
specified in Section 17 of this Agreement. The Debtor hereby waives any
objection that it may now or hereafter have to the venue of any such suit or any
such court or that such suit is brought in an inconvenient court.

      24. Waiver of Jury Trial. THE DEBTOR WAIVES ITS RIGHT TO A JURY TRIAL WITH
RESPECT TO ANY ACTION OR CLAIM ARISING OUT OF ANY DISPUTE IN CONNECTION WITH
THIS AGREEMENT, ANY RIGHTS, REMEDIES, OBLIGATIONS, OR DUTIES HEREUNDER, OR THE
PERFORMANCE OR ENFORCEMENT HEREOF OR THEREOF. Except as prohibited by law, the
Debtor waives any right which it may have to claim or recover in any litigation
referred to in the preceding sentence any special, exemplary, punitive or
consequential damages or any damages other than, or in addition to, actual
damages. The Debtor (i) certifies that neither the Secured Party nor any
representative, agent or attorney of the Secured


                                       12
<PAGE>

Party has represented, expressly or otherwise, that the Secured Party would not,
in the event of litigation, seek to enforce the foregoing waivers or other
waivers contained in this Agreement, and (ii) acknowledges that, in entering the
Purchase Agreement and the other Transaction Documents (as that term is defined
in the Purchase Agreement) to which the Secured Party is a party, the Secured
Party is relying upon, among other things, the waivers and certifications
contained in this Section 24.

      25. Miscellaneous. The headings of each section of this Agreement are for
convenience only and shall not define or limit the provisions thereof. This
Agreement and all rights and obligations hereunder shall be binding upon the
Debtor and its respective successors and assigns, and shall inure to the benefit
of the Secured Party and its successors and assigns. If any term of this
Agreement shall be held to be invalid, illegal or unenforceable, the validity of
all other terms hereof shall in no way be affected thereby, and this Agreement
shall be construed and be enforceable as if such invalid, illegal or
unenforceable term had not been included herein. The Debtor acknowledges receipt
of a copy of this Agreement.
