         SECURITY AGREEMENT made by OVATION PRODUCTS CORPORATION, a Delaware
corporation (the "Debtor"), in favor of ANDLINGER & COMPANY, INC., a Delaware
corporation (the "Secured Party"). Capitalized terms used but not defined herein
shall have the meanings ascribed to them in the Senior Secured Convertible Note
Purchase Agreement (the "Purchase Agreement"). In consideration of the agreement
of Secured Party to purchase the Note from the Debtor subject to the terms and
conditions set forth in the Purchase Agreement, and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the
Debtor and the Secured Party agree as follows:

         1. Grant of Security Interest. As collateral security for the payment
and performance when due of all Obligations (defined below), the Debtor hereby
collaterally assigns, mortgages, and pledges to Secured Party, and hereby grants
to Secured Party a continuing security interest in and right of setoff against,
all of the Debtor's right, title and interest in, to and under the Collateral
(defined below).

         "Collateral" means all the Debtor's present and future right, title and
         interest in and to any of the following property, wherever located and

         (hereinafter defined)), deposit accounts (and all monies, credit
         balances, deposits and other property of Debtor now or hereafter held

         limitation insurance proceeds and claims against third parties for loss
         or damage to or destruction of or other involuntary conversion of any
         kind or nature of any or all of the other Collateral, but excluding
         rights (other than payment rights) under agreements to the extent that
         the inclusion of such rights would cause a default by the Debtor under
         the terms of any agreement in effect on the date hereof. Any of the
         foregoing terms which are specifically defined in the Uniform
         Commercial Code as in effect in the State of New York shall have the

         hereof by Debtor.

         "UCC" shall have the meaning set forth in the definition of Collateral
         above.

         2.       Perfection of Security Interests.

                  (a) Debtor irrevocably and unconditionally authorizes Secured
Party (or its agent) to file at any time and from time to time such financing
statements with respect to the Collateral naming Secured Party or its designee
as the secured party and Debtor as debtor, as Secured Party may require, and
including any other information with respect to Debtor or otherwise required by
part 5 of Article 9 of the Uniform Commercial Code of such jurisdiction as
Secured Party may determine, together with any amendment and continuations with
respect thereto, which authorization shall apply to all financing statements
filed on, prior to or after the date hereof. Debtor hereby ratifies and approves
all financing statements naming Secured Party or its designee as secured party
and Debtor as debtor with respect to the Collateral (and any amendments with
respect to such financing statements) filed by or on behalf of Secured Party
prior to the date hereof and ratifies and confirms the authorization of Secured
Party to file such financing statements (and amendments, if any). In no event
shall Debtor at any time file, or permit or cause to be filed, any correction
statement or termination statement with respect to any financing statement (or
amendment or continuation with respect thereto) naming Secured Party or its
designee as secured party and Debtor as debtor, except as provided in Section
9-509(d) of the UCC.

                  (b) Debtor shall take any other actions reasonably requested
by Secured Party from time to time and necessary to cause the attachment,
perfection and first priority of, and the ability of Secured Party to enforce
the security interest of Secured Party in, any and all of the Collateral,
including, without limitation, (i) executing, delivering and, where appropriate,
filing financing statements and amendments relating thereto under the UCC or
other applicable law, to the extent, if any, that Debtor's

                                       3
<PAGE>

signature thereon is required therefor, (ii) causing Secured Party's name to be
noted as secured party on any certificate of title for a titled good if such
notation is a condition to attachment, perfection or priority of, or ability of
Secured Party to enforce, the security interest of Secured Party in such
Collateral, (iii) complying with any provision of any statute, regulation or
treaty of the United States as to any Collateral if compliance with such
provision is a condition to attachment, perfection or priority of, or ability of
Secured Party to enforce, the security interest of Secured Party in such
Collateral, (iv) using its best efforts to obtain the consents and approvals of
any Governmental Authority or third party, including, without limitation, any
consent of any licensor, lessor or other person obligated on Collateral, and
taking all actions required by any earlier versions of the UCC or by other law,
as applicable in any relevant jurisdiction.

         3. Secured Party's Rights and Obligations. Debtor shall remain liable
under all accounts receivable, instruments and documents and general
intangibles. Secured Party shall not have any obligation or liability under any
accounts receivable, instruments and documents or general intangibles by reason
of this Security Agreement or the exercise of Secured Party's rights and
remedies hereunder, nor shall Secured Party be required to perform the Debtor's
obligations pursuant thereto. Secured Party shall have no obligation to inquire
as to the sufficiency of any payment received by it on account of any of
Debtor's accounts receivable or to take any action to collect or enforce the
payment of any account receivable.

         4. Insurance. Debtor shall, upon the written request of the Secured
Party and at all times thereafter, maintain with financially sound and reputable
insurers adequate insurance with respect to the Collateral. In addition to such
requirements, the Debtor shall use its best efforts to comply with each of the
following requirements set forth in (a)-(c) below:

                  (a) Debtor shall furnish certificates, policies or
endorsements to Secured Party as Secured Party shall require as proof of such
insurance, and, if Debtor fails to do so, Secured Party is authorized, but not
required, to obtain such insurance at the expense of Debtor;

                  (b) All policies shall provide for at least thirty (30) days
prior written notice to Secured Party of any cancellation or reduction of
coverage and that Secured Party may act as attorney for Debtor in obtaining, and
at any time an Event of Default exists or has occurred and is continuing,
adjusting, settling, amending and canceling such insurance; and

                  (c) Debtor shall cause Secured Party to be named as a loss
payee and an additional insured (but without any liability for any premiums)
under such insurance policies and Debtor shall obtain non-contributory lender's
loss payable endorsements to all insurance policies in form and substance
satisfactory to Secured Party (such lender's loss payable endorsements shall
specify that the proceeds of such insurance shall be payable to Secured Party as
its interests may appear and further specify that Secured Party shall be paid
regardless of any act or omission by Debtor or any of its affiliates).

                                       4
<PAGE>

At its option, Secured Party may apply any insurance proceeds received by
Secured Party at any time to the cost of repairs or replacement of Collateral
and/or to payment of the Obligations, whether or not then due, in any order and
in such manner as Secured Party may determine or hold such proceeds as cash
collateral to secure the Obligations.

         5. Further Assurances. At Secured Party's request from time to time,
the Debtor will execute and deliver or cause to be executed and delivered any
and all such further agreements, instruments and documents and take such further
actions as Secured Party may reasonably deem desirable to evidence, perfect,
maintain and enforce the Secured Party's security interests and the priority
thereof in the Collateral and to otherwise effectuate the provisions or purposes
of this Security Agreement and the other Transaction Documents.

         6. Events of Default. The following shall each constitute an Event of
Default hereunder:

                  (a) occurrence of any Event of Default as defined in the Note;
and

                  (b) any failure of Debtor in the performance in any material
respect of any of the terms or conditions of, or any breach of any material
representation, covenant or warranty under, or any other material default under
this Agreement.

         7.       Remedies Upon Default.

                  (a) Upon the occurrence and during the continuance of any
Event of Default, and subject to (and without limitation of) the terms of the
Note and the Purchase Agreement (including, without limitation, the cure periods
(if any) with respect to such Events of Default set forth therein):

                           (i) Secured Party may declare all Obligations secured
hereby immediately due and payable and shall have all of the rights and remedies
of a secured party under the UCC or under other applicable law.

                           (ii) Secured Party may notify Debtor's account or
contract debtors (or other obligors whose obligations to Debtor secure this
agreement) of Secured Party's security interest and that such account or
contract debtors are to make payments directly to Secured Party. Secured Party
may send this notice in Debtor's name or in Secured Party's name, and at Secured
Party's request Debtor will join in Secured Party's notice, provide written
confirmation of Secured Party's security interest and request that payment be
sent to Secured Party. Secured Party may enforce this obligation by specific
performance. Secured Party may collect all amounts due on the accounts and
accounts receivable. Upon and after notification by Secured Party to Debtor
pursuant to this Section 7(a)(ii), Debtor shall hold any proceeds and
collections of any of the Collateral in trust for Secured Party and shall not
commingle such proceeds or collections with any other of Debtor's funds, and
Debtor shall deliver all such proceeds to Secured Party immediately upon
Debtor's receipt thereof in the identical form received and duly endorsed or
assigned to Secured Party.

                                       5
<PAGE>

                           (iii) with or without judicial process or the aid or
assistance of others, Secured Party may enter upon any premises on or in which
any of the Collateral may be located and take possession of the Collateral or
complete processing, manufacturing and repair of all or any portion of the
Collateral.

                           (iv) Secured Party may collect, foreclose, receive,
appropriate, setoff and realize upon any and all Collateral, which shall be
applied against the Obligations.

                           (v) Secured Party may remove any or all of the
Collateral from any premises on or in which the same may be located for the
purpose of effecting the sale, foreclosure or other disposition thereof for
application against the Obligations.

                           (vi) Secured Party may sell, lease, transfer, assign,
deliver or otherwise dispose of any and all Collateral (including entering into
contracts with respect thereto, public or private sales at any exchange,
broker's board, at any office of Secured Party or elsewhere) at such prices or
terms as Secured Party may deem reasonable, for cash, upon credit or for future
delivery, with the Secured Party having the right to purchase the whole or any
part of the Collateral at any such public sale, all of the foregoing being free
from any right or equity of redemption of Debtor, which right or equity of
redemption is hereby expressly waived and released by Debtor.

                           (vii) At the request of Secured Party, the Debtor
shall cause the Collateral, or such portion of the Collateral as Secured Party
may direct, to be assembled for Secured Party at such location (including,
without limitation, Debtor's business address) as Secured Party may request.

                           (viii) Secured Party may exercise any other rights
and remedies that it may have under the other Transaction Documents.

                  (b) If any of the Collateral is sold or leased by Secured
Party upon credit terms or for future delivery, the Obligations shall not be
reduced as a result thereof until payment therefor is finally collected by
Secured Party. If notice of disposition of Collateral is required by law, ten
(10) days prior notice by Secured Party to Debtor designating the time and place
of any public sale or the time after which any private sale or other intended
disposition of Collateral is to be made, shall be deemed to be reasonable notice
thereof and Debtor waives any other notice. In the event Secured Party
institutes an action to recover any Collateral or seeks recovery of any
Collateral by way of prejudgment remedy, Debtor waives the posting of any bond
which might otherwise be required. Any such sale may take place from Debtor's
location or such other location as Secured Party may designate.

<PAGE>

                  (c) Debtor hereby irrevocably appoints Secured Party as its
true and lawful attorney-in-fact with full power of substitution, effective upon
the occurrence and continuation of an Event of Default, to take any of the
foregoing actions set forth in this Section in the name of the Debtor to carry
out the terms of this Agreement and to protect, enforce, preserve or perfect
Secured Party's rights hereunder and under the other Transaction Documents. Such
power of attorney is irrevocable until this Agreement is terminated and shall be
deemed to be coupled with an interest.

                  (d) For the purpose of enabling Secured Party to exercise the
rights and remedies hereunder and only for such purpose, effective upon the
occurrence and during the continuance of an Event of Default, Debtor hereby
grants to Secured Party, to the extent assignable, an irrevocable, non-exclusive
license (exercisable without payment of royalty or other compensation to Debtor)
to use, assign, license or sublicense any of the trademarks, service-marks,
trade names, business names, trade styles, designs, logos and other source of
business identifiers and other Intellectual Property and general intangibles now
owned or hereafter acquired by Debtor, wherever the same maybe 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.

                  (e) Secured Party may apply the cash proceeds of Collateral
actually received by Secured Party from any sale, lease, foreclosure or other
disposition of the Collateral to payment of the Obligations, in whole or in part
and in such order as Secured Party may elect, whether or not then due; provided,
however, that such proceeds will be first applied against any accrued but unpaid
interest then due. Debtor shall remain liable to Secured Party for the payment
of any deficiency with interest at the Default Rate (as defined in the Note) and
all costs and expenses of collection or enforcement, including attorneys' fees
and legal expenses.

         8. Waiver of Counterclaims. Debtor waives all rights to interpose any
claims, deductions, setoffs or counterclaims of any nature (other then
compulsory counterclaims) in any action or proceeding brought by the Secured
Party with respect to this Security Agreement, the other Transaction Documents,
the Obligations, the Collateral or any matter arising therefrom or relating
hereto or thereto.

         9. Governing Law. The provisions of Section 10(c) of the Purchase
Agreement ("Governing Law/Jurisdiction") are hereby incorporated herein by
reference and shall be deemed to govern this Agreement as well.

         10. Miscellaneous. Expenses of enforcing Secured Party's rights
hereunder including, but not limited to, Secured Party's reasonable attorneys'
fees and other expenses shall be payable by Debtor on demand and shall
constitute Obligations hereunder. None of the terms or provisions of this
Agreement may be waived, altered, modified or amended except by an instrument in
writing, duly executed by Secured Party and Debtor. Secured Party's rights and
remedies hereunder or under any other agreement or instrument shall be
cumulative, may be exercised singly or concurrently and are not exclusive of any
other rights or remedies provided by law. This Agreement shall be

                                       7

assignable only in conjunction with an assignment of the Obligations, to the
extent permitted under the Purchase Agreement. The notice provisions of the

         2.  GRANT OF SECURITY; COLLATERAL ASSIGNMENT.

         2.1 Grant of Security Interest. As collateral security for the complete
and timely performance and satisfaction of all Obligations (as defined in the
Security Agreement between Debtor and Secured Party dated as of even date hereof
("Security Agreement")), the Debtor hereby unconditionally grants to Secured
Party, a continuing security interest in and lien on the Patent Collateral, and
pledges, mortgages and hypothecates the Patent Collateral to Secured Party.

         2.2 Supplemental to Transaction Documents. The parties expressly
acknowledge and agree that they have executed and delivered the Transaction
Documents pursuant to which the Debtor granted to Secured Party, a continuing
security interest in and lien on the Collateral (as defined in the Security
Agreement) (including the Patent Collateral). In no event shall this Patent
Security Agreement, or the recordation of this Patent Security Agreement (or any
document hereunder) with the PTO, or any other governmental or public office or
agency, adversely affect or impair, in any way or to any extent, the other
Transaction Documents, the security interest of Secured Party in the Collateral
(including the Patent Collateral) pursuant to the other Transaction Documents,
the attachment and perfection of such security interest under the UCC (as
defined in the Security Agreement), or the present or future rights and
interests of Secured Party in and to the Collateral under or in connection with
this Patent Security Agreement, the other Transaction Documents, and/or the UCC.
Any and all rights and interests of Secured Party in and to the Patent
Collateral (and any and all obligations of the Debtor with respect to the Patent
Collateral) provided herein, or arising hereunder or in connection herewith,
shall only supplement and be cumulative and in addition to the rights and
interests of Secured Party (and the obligations of the Debtor ) in, to or with
respect to the Collateral (including the Patent Collateral) provided in or
arising under or in connection with the other Transaction Documents.

         3. REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE DEBTOR . The Debtor
represents and warrants to, and covenants and agrees with, Secured Party, as
follows (provided, however, that, notwithstanding anything herein to the
contrary, none of the obligations and/or restrictions set forth in Section 3.1,
3.2 and 3.3 shall apply to any Patent Collateral that Debtor determines, in its
reasonable business judgment, is no longer necessary or material to the conduct
of its business or operations):

         3.1 Title. The Debtor will take all reasonable actions as necessary to
defend its right, title and interests in and to the Patent Collateral against
claims of any third parties.

         3.2 Maintenance of Patent Collateral. The Debtor shall take such
reasonable actions (including but not limited to institution and maintenance of
suits, proceedings or actions) necessary to maintain, protect, preserve, care
for and enforce the Patent Collateral.

                                       3
<PAGE>

         3.3 No Infringements. The Debtor shall use reasonable efforts to
protect against any infringement or unauthorized or improper use of the Patents.
To the best of Debtor's knowledge and belief, there is at present no material
infringement or unauthorized or improper use of the Patents or the Patent Rights
related thereto. In the event any such infringement or unauthorized or improper
use by any third party has been reasonably established by the Debtor , the
Debtor shall promptly notify Secured Party and Secured Party shall have the
right to sue and recover therefor and to retain any and all damages so recovered
or obtained.

         3.4 Recording at the PTO. Debtor acknowledges that Secured Party may
cause this Patent Security Agreement and Schedule A along with any amendments
made thereto to be recorded with the PTO.

         4.  REMEDIES UPON AN EVENT OF DEFAULT. During the continuance of an
Event of Default:

         (a) Secured Party may declare all Obligations secured hereby
immediately due and payable and shall have all of the rights and remedies of a
secured party under the UCC or under other applicable law.

         (b) Secured Party may notify any obligors with respect to the Patent
Collateral of Secured Party's security interest and that such obligors are to
make payments directly to Secured Party. Secured Party may send this notice in
Debtor 's name or in Secured Party's name, and at Secured Party's request Debtor
will join in Secured Party's notice, provide written confirmation of Secured
Party's security interest and request that payment be sent to Secured Party.
Secured Party may enforce this obligation by specific performance. Secured Party
may collect all amounts due from such obligors. Upon and after notification by
Secured Party to Debtor pursuant to this Section 4(b), Debtor shall hold any
proceeds and collections of any of the Patent Collateral in trust for Secured
Party and shall not commingle such proceeds or collections with any other of
Debtor 's funds, and Debtor shall deliver all such proceeds to Secured Party
immediately upon Debtor 's receipt thereof in the identical form received and
duly endorsed or assigned to Secured Party.

         (c) Secured Party will give to the Debtor reasonable notice of the time
and place of any public sale of Patent Collateral or of the time after which any
private sale or other intended disposition thereof is to be made. Such
requirement of reasonable notice shall be met if such notice is delivered to the
address of the Debtor set forth in the Purchase Agreement at least ten (10) days
before the time of the proposed sale or disposition. Any such sale may take
place from Debtor 's location or such other location as Secured Party may
designate. Debtor shall remain liable for any deficiency in payment of the
Obligations after any such sale.

         (d) No Obligation of Secured Party. Nothing herein shall be construed
as obligating Secured Party to take any of the foregoing actions at any time.

         5.  LIABILITIES, INDEMNITY AND COSTS.

         5.1 Liability for Uses of Patent Collateral. The Debtor shall be liable
for any and all uses or misuses of and the practice, manufacture, sales (or
other transfers or dispositions) of any of the Patent Collateral by the Debtor
and its affiliates. The Debtor shall also be exclusively liable for any claim,
suit, loss, damage, expense or liability arising out of or in connection with
the fault, negligence, acts or omissions of the Debtor(regardless of whether
such fault, negligence, acts or omissions occurred or occur prior to or after
the applicable license termination).

         5.2 License Agreement Obligations. Nothing in this Patent Security
Agreement shall relieve the Debtor from any performance of any covenant,
agreement or obligation of the Debtor under any license agreement now or
hereafter in effect licensing any part of the Patent Collateral, or from any
liability to any licensee or licensor under any such license agreement or to any
other party, or shall impose any liability on Secured Party for any act or
omission of the Debtor in connection with any such license agreement.

         6. POWER OF ATTORNEY. The provisions of this Section 6 shall be subject
in all events to the terms and conditions of the Purchase Agreement.

         6.1 Grant. For the purpose of enabling Secured Party to exercise the
rights and remedies hereunder and only for such purpose, the Debtor hereby
grants to Secured Party, and any officer or agent of Secured Party as Secured
Party may designate in its sole discretion, a power of attorney, thereby
constituting and appointing Secured Party (and Secured Party's designee) its
true and lawful attorney-in-law and attorney-in-fact, effective upon the
occurrence and during the continuation of an Event of Default, for the purpose
of assigning, selling, licensing or otherwise transferring or disposing of all
right, title and interest of the Debtor in and to any of the Patent Collateral
in accordance with the terms hereof. The Debtor hereby ratifies all that such
attorney shall lawfully do or cause to be done by virtue hereof.

         6.2 Irrevocable. The foregoing power of attorney is coupled with an
interest and is irrevocable until this Patent Security Agreement is terminated.

         7. GENERAL PROVISIONS.

         7.1 Security Agreement Controls. This Patent Security Agreement is
supplemental to the Security Agreement. In the event of any irreconcilable
conflict between the provisions of this Patent Security Agreement and the
Security Agreement the provisions most advantageous to Secured Party and most
restrictive to Debtor shall control.

         7.2 Specific Enforcement. Due to the unique nature of the Patent
Collateral, and in order to preserve its value, the Debtor agrees that the
Debtor 's agreements, duties

                                       5
