this Agreement, the Warrant Holders shall surrender all of the Thermoflow
Warrants in exchange for the VitriSeal Warrants in the amounts set forth in

on behalf of the Stockholders), THERMOFLOW, and VITRISEAL shall each take all
such actions as may be reasonably necessary or appropriate in order to
effectuate the transactions contemplated hereby and to make the Reorganization

the Board of Directors of THERMOFLOW. A copy of the THERMOFLOW resolutions
evidencing this election of DAVIS to the THERMOFLOW Board of Directors is

                                   ARTICLE III

                  REPRESENTATIONS AND WARRANTIES OF THERMOFLOW

         Except as set forth in the Schedule of Exceptions attached hereto and
incorporated herein by reference as Exhibit "G," THERMOFLOW represents and
warrants to, and covenants with, VITRISEAL, as of the date hereof and as of the
Closing Date, as follows:

         3.1 ORGANIZATION AND CORPORATE POWER. THERMOFLOW is a corporation duly
organized, in good standing, and validly existing under the laws of Nevada.
THERMOFLOW has all requisite corporate power and authority to conduct its
business as now being conducted and to own and lease the properties which it now
owns and leases. The charter documents of THERMOFLOW as amended to date, the
Bylaws of THERMOFLOW as amended to date, and the resolutions of THERMOFLOW's
stockholders (if necessary) and directors authorizing the execution, delivery,
and performance of this Agreement, all certified by the President and the
Secretary, which have previously been provided to VITRISEAL by THERMOFLOW, are
true and complete copies thereof as currently in effect.

         3.2 AUTHORIZATION. THERMOFLOW has full corporate power, legal capacity,
and authority to enter into this Agreement, to execute all attendant documents
and instruments contemplated hereby, and to perform all of its obligations
hereunder. This Agreement, and each and every other agreement, document and
instrument to be executed by THERMOFLOW in connection herewith, has been
effectively authorized by all necessary action on the part of THERMOFLOW,
including without limitation the approval of THERMOFLOW's Board of Directors
(and stockholders, if necessary), which authorizations remain in full force and
effect, have been duly executed and delivered by THERMOFLOW. A copy of the
resolutions of the THERMOFLOW Board of Directors and (stockholders, if
necessary) authorizing the execution, delivery, and performance of this
Agreement, all certified by the Secretary of THERMOFLOW, are attached hereto as
Exhibit "H." No other authorizations or proceedings on the part of THERMOFLOW,
the Stockholders, the Warrant Holders, or otherwise, are required to authorize
this Agreement and/or the transactions contemplated hereby. This Agreement
constitutes the legal, valid and binding obligation of THERMOFLOW, the
Stockholders, and the Warrant Holders, and is enforceable against each of them
in accordance with its terms, except as enforcement may be limited by
bankruptcy, insolvency, reorganization, priority or other laws or court
decisions relating to or affecting generally the enforcement of creditors'
rights or affecting generally the availability of equitable remedies.

                                     Page 7
<PAGE>

         3.3. NO CONFLICTS; NO CONSENTS. Other than that set forth in the
Schedule of Exceptions, neither the execution and delivery of this Agreement,
nor the consummation by THERMOFLOW, the Stockholders, or the Warrant Holders of
any of the transactions contemplated hereby, or compliance with any of the
provisions hereof, will (i) conflict with or result in a material breach of,
violation of, or default under, any of the terms, conditions or provisions of
any material note, bond, mortgage, indenture, license, lease, credit agreement
or other agreement, document, instrument, permit, authorization, or obligation
(including, without limitation, any of its charter documents) to which
THERMOFLOW is a party or by which it or any of its assets or properties may be
bound, or (ii) violate any judgment, order, injunction, decree, statute, rule or
regulation applicable to THERMOFLOW or its assets or properties, the violation
of which would have a material adverse effect upon the business, properties, or
assets, or in the condition (financial or otherwise) of THERMOFLOW. No
authorization, consent or approval of any public body or authority was or is
necessary for the consummation by THERMOFLOW, the Stockholders, or the Warrant
Holders of the transactions contemplated by this Agreement.

         3.4 CAPITALIZATION. The authorized capital stock of THERMOFLOW consists
of 30,000,000 shares of common stock, par value $.001 per share. As of the
Effective Date, there are 1,932,300 shares of common stock issued and
outstanding. Except as set forth in Exhibit "A," no options or warrants to
purchase common stock of THERMOFLOW have been granted or are outstanding other
than the 79,700 Thermoflow Warrants outstanding as set forth in Exhibit "A."
THERMOFLOW does not have any contracts or obligations to issue, redeem,
repurchase, or otherwise reacquire any equity security of THERMOFLOW. All of the
Thermoflow Shares are duly authorized, validly issued and outstanding, fully
paid, and nonassessable and have been issued in conformity with all applicable
laws.

         3.5 NO PENDING MATERIAL LITIGATION OR PROCEEDINGS. There are no
actions, suits or proceedings pending or, to the best knowledge of THERMOFLOW,
threatened against or affecting THERMOFLOW affecting the Stockholders' or
Warrant Holders' rights in the Thermoflow Shares or the Thermoflow Warrants
(including actions, suits or proceedings where liabilities may be adequately
covered by insurance) at law or in equity or before or by any federal, state,
municipal or other governmental department, commission, court, board, bureau,
agency or instrumentality, domestic or foreign, or affecting any of the
officers, directors of THERMOFLOW, the Stockholders, or the Warrant Holders in
connection with the business, operations or affairs of either of them, which
might reasonably be expected to result in any material adverse change in the
business, properties or assets, or in the condition (financial or otherwise) of
THERMOFLOW, or which question or challenge the Reorganization. THERMOFLOW is not
subject to any voluntary or involuntary proceeding under federal bankruptcy laws
and has not made an assignment for the benefit of creditors.

         3.6 FINANCIAL STATEMENTS; ABSENCE OF UNDISCLOSED LIABILITIES AND
CERTAIN DEVELOPMENTS. Attached hereto as Exhibit "I" are the unaudited and
internally prepared financial statements of THERMOFLOW, for the year ended
December 31, 1999 and the quarter ended March 31, 2000, consisting of
THERMOFLOW's balance sheets as of such dates (the "Thermoflow Balance Sheets"),
the related statements of profit or loss for the periods then ended, and the
respective notes thereto. Such financial statements (and the notes related
thereto) are herein sometimes collectively referred to as the "Thermoflow
Financial Statements." The Thermoflow Financial Statements (i) are derived from
the books and records of THERMOFLOW, which books and records have been
consistently maintained in a manner which reflects, and such books and records
do fairly and accurately reflect, the assets and liabilities of THERMOFLOW, and
(ii) fairly present in all material respects the financial condition of
THERMOFLOW on the date of such statements and the results of its operations for
the periods indicated, except as may be disclosed in the notes thereto. Except
as and to the extent reflected or reserved against in the Thermoflow Balance
Sheets, and as to matters arising in the ordinary course of its business since
the respective date of the Thermoflow Balance Sheets, THERMOFLOW has no
liability or obligation of a type required by generally accepted accounting
principles to be reflected in the Thermoflow Balance Sheets (whether accrued, to
become due, contingent or otherwise) which individually or in the aggregate
could have a materially adverse effect on the business, assets, condition
(financial or otherwise) or prospects of THERMOFLOW. Except as set forth in
Exhibit "I," since March 31, 2000, there has been (a) no declaration, setting
aside or payment of any dividend or other distribution with respect to the
Thermoflow Shares or redemption, purchase or other acquisition of any of the

herein by this reference, contains a complete and accurate legal description of
each parcel of real property owned by or leased to and occupied or subleased by
THERMOFLOW, and THERMOFLOW neither owns or leases, nor occupies, any other real
property. The building and all fixtures and improvements located on such real
property are in good operating condition, ordinary wear and tear excepted. To
the best of its knowledge, THERMOFLOW is not in violation of any material
zoning, building or safety ordinance, regulation or requirement, or other law or
regulation applicable to the operation of owned or leased properties, and
THERMOFLOW has not received any notice of violation with which its has not
complied. All leases of real property to which THERMOFLOW is a party and which
are material to the business of THERMOFLOW are fully effective in accordance
with their respective terms and afford THERMOFLOW peaceful and undisturbed
possession of the subject matter of the lease, and, to the best knowledge of
THERMOFLOW, there exists no default on the part of THERMOFLOW or termination
thereof.

         3.12 TANGIBLE PERSONAL PROPERTY. Exhibit "K" attached hereto sets forth
a complete list of all items of tangible personal property owned or leased and
used by THERMOFLOW in the current conduct of its business, where the original
cost was in excess of $1,000. THERMOFLOW has good and marketable title to, or in
the case of leased equipment a valid leasehold interest in, and is in possession
of, all such items of personal property owned or leased by it, free and clear of
all title defects, mortgages, pledges, security interests conditional sales
agreements, liens, restrictions or encumbrances, the presence of which would
result in a material adverse change in the business, properties, or assets, or
the condition (financial or otherwise) of THERMOFLOW. Included in Exhibit "K" is
a list of all outstanding equipment leases and maintenance agreements to which
THERMOFLOW is a party as lessee and which individually provide for future lease
payments in excess of $1,000 per month, with the identities of the other parties
to all such leases and agreements shown thereon. All leases of tangible personal
property to which THERMOFLOW is a party and which are material to the business
of THERMOFLOW are fully effective in accordance with their respective terms,
and, to the best knowledge of THERMOFLOW, there exists no default on the part of
THERMOFLOW or termination thereof, the presence of which would result in a
material adverse change in the business, properties, or assets, or the condition
(financial or otherwise) of THERMOFLOW. Each item of capital equipment reflected
in the Thermoflow Balance Sheets which is used in the current conduct of

                                    Page 11
<PAGE>

THERMOFLOW's business is in good operating and usable condition and repair,
ordinary wear and tear excepted, and is and will be suitable for use in the
ordinary course of THERMOFLOW's business and fit for its intended purposes.

         3.13 TAX MATTERS. THERMOFLOW has, since its inception, duly filed all
material federal, state, municipal, local, and other tax returns required to
have been filed by it in those jurisdictions where the nature or conduct of its
business requires such filing and where the failure to so file would be
materially adverse to THERMOFLOW. Copies of all such tax returns have been made
available for inspection by VITRISEAL prior to the execution hereof. All
federal, state, municipal, local, and other taxes shown to be due on such
returns have been paid or will be paid prior to the time they become delinquent.
The amounts reflected in the Thermoflow Balance Sheets as liabilities or
reserves for taxes which are due but not yet payable are sufficient for the
payment of all accrued and unpaid taxes of the types referred to hereinabove and
THERMOFLOW has no knowledge of any proposed liability for taxes to be imposed
upon its properties or assets for which there is not adequate reserve reflected
in the Thermoflow Financial Statements.

         3.14 CONTRACTS AND COMMITMENTS. THERMOFLOW has no contract, agreement,
obligation or commitment, written or oral, expressed or implied, which involves
a commitment or liability of THERMOFLOW in excess of $1,000 (other than
obligations which are included in accounts payable), and no union contracts,
employee or consulting contracts, financing agreements, debtor or creditor
arrangements, licenses, franchise, manufacturing, distributorship or dealership
agreements, leases, or bonus, health or stock option plans, except as described
in Exhibits "G" and "I." True and complete copies of all such contracts and
other agreements listed in Exhibits "G" and "I" which involve a commitment or
liability of THERMOFLOW in excess of $1,000 have been made available to
VITRISEAL prior to the execution hereof. As of the date hereof, to the best of
their knowledge, there exist no circumstances that would affect the validity or
enforceability of any of such contracts and other agreements in accordance with
their respective terms. THERMOFLOW has performed and complied in all material
respects with all obligations required to be performed by it to date under, and
is not in default (without giving effect to any required notice or grace period)
under, or in breach of, the terms, conditions or provisions of any of such
contracts and other agreements. The validity and enforceability of any contract
or other agreement described herein has not been and shall not be materially and
adversely affected by the execution and delivery of this Agreement without any
further action. THERMOFLOW has no contract, agreement, obligation or commitment
which to the best knowledge of THERMOFLOW requires or will require future
expenditures (including internal costs and overhead) in excess of reasonably
anticipated receipts, nor which is likely to be materially adverse to
THERMOFLOW's business, assets, condition (financial and otherwise), or
prospects.

LIABILITIES; NO ADVERSE CHANGES. Attached hereto as Exhibit "R" are the audited
financial statements of VITRISEAL for the years ended December 31, 1999 and
1998, consisting of VITRISEAL's balance sheet as of such dates (the "VitriSeal
Balance Sheets"), the related statements of profit or loss for the periods then
ended, and the respective notes thereto. Such financial statements (and the
notes related thereto) are herein sometimes collectively referred to as the
"VITRISEAL Financial Statements." The VITRISEAL Financial Statements (i) are
derived from the books and records of VITRISEAL, which books and records have
been consistently maintained in a manner which reflects, and such books and
records do fairly and accurately reflect, the assets and liabilities of
VITRISEAL, (ii) fairly and accurately present the financial condition of
VITRISEAL

                                    Page 16
<PAGE>

on the date of such statements and the results of its operations for the periods
indicated, except as may be disclosed in the notes thereto, and (iii) have been
prepared in all material respects in accordance with generally accepted
accounting principles consistently applied throughout the periods involved
(except as otherwise disclosed in the notes thereto). Except as and to the
extent reflected or reserved against in the VitriSeal Balance Sheets, and as to
matters arising in the ordinary course of its business since the respective
dates of the VitriSeal Balance Sheets, VITRISEAL has no liability or obligation
(whether accrued, to become due, contingent or otherwise) which individually or
in the aggregate could have a materially adverse effect on the business, assets,
condition (financial or otherwise) or prospects of VITRISEAL. Except as set
forth in Exhibit "R," since the dates of the respective VitriSeal Balance
Sheets, there has been (a) no declaration, setting aside or payment of any
dividend or other distribution with respect to the common stock of VITRISEAL or
redemption, purchase or other acquisition of any of the common stock of
VITRISEAL or any split-up or other recapitalization relative to any of the
common stock of VITRISEAL or any action authorizing or obligating VITRISEAL to
do any of the foregoing, (b) no loss, destruction or damage to any material
property or asset of VITRISEAL, whether or not insured, (c) no acquisition or
disposition of assets (or any contract or arrangement therefor), or any other
transaction by VITRISEAL otherwise than for fair value and in the ordinary
course of business, (d) no discharge or satisfaction by VITRISEAL of any lien or
encumbrance or payment of any obligation or liability (absolute or contingent)

liabilities incurred since the date thereof in the ordinary course of business,
(e) no sale, assignment or transfer by VITRISEAL of any of its tangible or
intangible assets except in the ordinary course of business, cancellation by
VITRISEAL of any debts, claims or obligations, or mortgage, pledge, subjection

material change in the compensation of any director, officer or employee,
whether directly or by means of any bonus, pension plan, contract or commitment,
(g) no write-off or material reduction in the carrying value of any asset which
is material to the business of VITRISEAL, (h) no disposition or lapse of rights
as to any intangible property which is material to the business of VITRISEAL,
(i) except for ordinary travel advances, no loans or extensions of credit to
stockholders, officers, directors or employees of VITRISEAL, (j) no agreement to
do any of the things described in this Section 4.5, and (k) no material adverse
change in the condition (financial or otherwise) of VITRISEAL or in its assets,
liabilities, properties, business, or prospects.

         4.6 TAX MATTERS. VITRISEAL has, since its inception, accurately
prepared and duly filed all federal, state, county and local tax returns
required to have been filed by it in those jurisdictions where the nature or
conduct of its business requires such filing and where the failure to so file
would be materially adverse to VITRISEAL. Copies of all such tax returns have
been made available for inspection by

                                    Page 17
<PAGE>

THERMOFLOW and the Stockholders prior to the execution hereof. All federal,
state, county and local taxes, including but not limited to those taxes due with
respect to VITRISEAL's properties, income, gross receipts, excise, occupation,
franchise, permit, licenses, sales, payroll, and inventory due and payable as of
the date of the Closing by VITRISEAL have been paid or will be paid prior to the
time they become delinquent. The amount reflected in the VitriSeal Balance
Sheets of VITRISEAL as liabilities or reserves for taxes which are due but not
yet payable is sufficient for the payment of all accrued and unpaid taxes of the
types referred to hereinabove.

         4.7 NO PENDING MATERIAL LITIGATION OR PROCEEDINGS. There are no
actions, suits or proceedings pending or, to the best knowledge of VITRISEAL,
threatened against or affecting VITRISEAL (including actions, suits or
proceedings where liabilities may be adequately covered by insurance) at law or
in equity or before or by any federal, state, municipal or other governmental
department, commission, court, board, bureau, agency or instrumentality,
domestic or foreign, or affecting any of the Stockholders, officers or directors
of VITRISEAL in connection with the business, operations or affairs of
VITRISEAL, which might result in any material adverse change in the business,
properties or assets, or in the condition (financial or otherwise) of VITRISEAL,
or which question or challenge the Reorganization. VITRISEAL is not subject to
any voluntary or involuntary proceeding under applicable bankruptcy laws and has
not made an assignment for the benefit of creditors.

         4.8 COMPLIANCE WITH LAWS. VITRISEAL (i) holds all licenses, franchises,
permits and authorizations necessary for the lawful conduct of its business as
presently conducted and which the failure to so hold would have a material
adverse effect upon the business, properties, or assets, or the condition
(financial or otherwise) of VITRISEAL, and (ii) has complied with all applicable
statutes, laws, ordinances, rules and regulations of all governmental bodies,
agencies and subdivisions having, asserting or claiming jurisdiction over it,
which the failure to comply with would have a material adverse effect upon the
business, properties, or assets, or the condition (financial or otherwise) of
VITRISEAL.

         4.9 DISCLOSURE. Neither this Agreement, nor any certificate, exhibit,
or other written document or statement, furnished to THERMOFLOW or the
Stockholders by or on behalf of VITRISEAL in connection with the transactions
contemplated by this Agreement contained or contains any untrue statement of a
material fact or omitted or omits to state a material fact necessary to be
stated in order to make the statements contained herein or therein, when taken
as a whole, not misleading. VITRISEAL has no knowledge of any fact which has not
been disclosed in writing to THERMOFLOW or the Stockholders which may reasonably
be expected to materially and adversely affect the business, properties,
operations, and/or prospects of VITRISEAL or the ability of VITRISEAL to perform
all of the obligations to be performed by VITRISEAL under this Agreement and/or
any other agreement between THERMOFLOW and

                                    Page 18
<PAGE>

VITRISEAL to be entered into pursuant to any provision of this Agreement. A copy
of VITRISEAL's Annual Report on Form 10-KSB for the year ended December 31, 1999
(the "Annual Report") and Proxy Statement for its annual stockholders meeting on
March 18, 2000 are attached hereto as Exhibits "S" and "T."

         4.10 SUBSIDIARIES. VITRISEAL has no subsidiaries other than Dancor,
Inc. and no investments, directly or indirectly, or other financial interest in
any other corporation or business organization, joint venture or partnership of
any kind whatsoever except as reflected in the VITRISEAL Financial Statements.

         4.11 OFFERING. Subject to the accuracy of the Stockholders'
representations in Section 5.4 hereof, the offer, sale, and issuance of the
VitriSeal Shares to be issued in conformity with the terms of this Agreement and
the transactions contemplated hereby, constitute transactions exempt from the
registration requirements of Section 5 of the Securities Act of 1933, as
amended, and from all applicable state registration or qualification
requirements.

         4.12 REAL PROPERTY. The Annual Report attached hereto as Exhibit "S"
contains a description of the real property leased to and occupied by VITRISEAL,
and except as set forth in Exhibit "P," VITRISEAL neither owns or leases, nor
occupies, any other real property. The building and all fixtures and
improvements located on such real property are in good operating condition,
ordinary wear and tear excepted. To the best of its knowledge, VITRISEAL is not
in violation of any material zoning, building or safety ordinance, regulation or
requirement, or other law or regulation applicable to the operation of owned or
leased properties, and VITRISEAL has not received any notice of violation with
which its has not complied. All leases of real property to which VITRISEAL is a
party and which are material to the business of VITRISEAL are fully effective in
accordance with their respective terms and afford VITRISEAL peaceful and
undisturbed possession of the subject matter of the lease, and, to the best
knowledge of VITRISEAL, there exists no default on the part of VITRISEAL or
termination thereof.

is in possession of, all such items of personal property owned or leased by it,
free and clear of all title defects, mortgages, pledges, security interests
conditional sales agreements, liens, restrictions or encumbrances, the presence
of which would result in a material adverse change in the business, properties,
or assets, or the condition (financial or otherwise) of VITRISEAL. All leases of
tangible personal property to which VITRISEAL is a party and which are material

presence of which would result in a material adverse change in the business,
properties, or assets, or the condition (financial or otherwise) of VITRISEAL.
Each item of capital equipment reflected in the VitriSeal Balance Sheets which
is used in the current conduct of VITRISEAL's business is in good operating and
usable condition and repair, ordinary wear and tear excepted, and is and will be
suitable for use in the ordinary course of VITRISEAL's business and fit for its
intended purposes.

obligation or commitment, written or oral, expressed or implied, which involves

contracts, employee or consulting contracts, financing agreements, debtor or
creditor arrangements, licenses, franchise, manufacturing, distributorship or
dealership agreements, leases, or bonus, health or stock option plans, except as
described in Exhibit "P." True and complete copies of all such contracts and

material respects with all obligations required to be performed by it to date
under, and is not in default (without giving effect to any required notice or

contract or other agreement described herein has not been and shall not be
materially and adversely affected by the execution and delivery of this
Agreement without any further action. VITRISEAL has no contract, agreement,
obligation or commitment which requires or will require future expenditures

assets, condition (financial and otherwise), or prospects.

presence of which would not result in a material adverse change in the business,
properties, or assets, or the condition (financial or otherwise) of VITRISEAL,

following the Closing will not conflict with, infringe upon, or otherwise
violate any rights of others. VITRISEAL has not used and is not making use of

         Except as set forth in the Schedule of Exceptions attached hereto and
incorporated herein by reference as Exhibit "G," LIQUITEK represents and
warrants to, and covenants with, VITRISEAL, as of the date hereof and as of the

and authority to enter into this Agreement, to execute all attendant documents
and instruments contemplated hereby, and to perform all of its obligations
hereunder. This Agreement, and each and every other agreement, document and
instrument to be executed by LIQUITEK in connection herewith, has been

including without limitation the approval of LIQUITEK's Board of Directors (and
stockholders, if necessary), which authorizations remain in full force and

certified by the Secretary of LIQUITEK, are attached hereto as Exhibit "H." No
other authorizations or proceedings on the part of LIQUITEK or Stockholders, or
otherwise, are required to authorize this Agreement and/or the transactions
contemplated hereby. This Agreement constitutes the legal, valid and binding
obligation of LIQUITEK and the Stockholders and is enforceable against each of
them in accordance with its terms, except as enforcement may be limited by
bankruptcy, insolvency, reorganization, priority or other laws or court
decisions relating to or affecting generally the enforcement of creditors'
rights or affecting generally the availability of equitable remedies.

         3.3. NO CONFLICTS; NO CONSENTS. Other than that set forth in the
Schedule of Exceptions, neither the execution and delivery of this Agreement,
nor the consummation by LIQUITEK or the Stockholders of any of the transactions
contemplated hereby, or compliance with any of the provisions hereof, will (i)
conflict with or result in a material breach of, violation of, or default under,
any of the terms, conditions or provisions of any material note, bond, mortgage,
indenture, license, lease, credit agreement or other agreement, document,
instrument, permit, authorization, or obligation (including, without limitation,
any of its charter documents) to which LIQUITEK is a party or by which it or any
of its assets or properties may be bound, or (ii) violate any judgment, order,
injunction, decree, statute, rule or regulation applicable to LIQUITEK or its
assets or properties, the violation of which would have a material adverse
effect upon the business, properties, or assets, or in the condition (financial
or otherwise) of LIQUITEK. No authorization, consent or approval of any public
body or authority was or is necessary for the consummation by LIQUITEK or the
Stockholders of the transactions contemplated by this Agreement.

         3.4 CAPITALIZATION. The authorized capital stock of LIQUITEK consists
of 30,000,000 shares of common stock, par value $.001 per share. As of the
Effective Date, there are 20,000,000 shares of common stock issued and
outstanding. No options or warrants to purchase common stock of LIQUITEK have
been granted or are outstanding. LIQUITEK does not have any contracts or
obligations to issue,

<PAGE>

redeem, repurchase, or otherwise reacquire any equity security of LIQUITEK,
provided that all Liquitek Shares owned by Thermoflow Corporation shall be
surrendered and canceled upon the Closing hereunder and Thermoflow Corporation,
as a Stockholder pursuant to this Agreement, shall not receive any of the
Vitriseal Shares given in exchange for the Liquitek Shares. All of the Liquitek
Shares are duly authorized, validly issued and outstanding, fully paid, and
nonassessable and have been issued in conformity with all applicable laws.

         3.5 NO PENDING MATERIAL LITIGATION OR PROCEEDINGS. There are no
actions, suits or proceedings pending or, to the best knowledge of LIQUITEK,
threatened against or affecting LIQUITEK affecting the Stockholders' rights in
the Liquitek Shares (including actions, suits or proceedings where liabilities
may be adequately covered by insurance) at law or in equity or before or by any
federal, state, municipal or other governmental department, commission, court,
board, bureau, agency or instrumentality, domestic or foreign, or affecting any
of the officers, directors of LIQUITEK or the Stockholders in connection with
the business, operations or affairs of either of them, which might reasonably be
expected to result in any material adverse change in the business, properties or
assets, or in the condition (financial or otherwise) of LIQUITEK, or which
question or challenge the Reorganization. LIQUITEK is not subject to any
voluntary or involuntary proceeding under federal bankruptcy laws and has not
made an assignment for the benefit of creditors.

         3.6 FINANCIAL STATEMENTS; ABSENCE OF UNDISCLOSED LIABILITIES AND
CERTAIN DEVELOPMENTS. Attached hereto as Exhibit "I" are the unaudited and
internally prepared financial statements of LIQUITEK, for the year ended
December 31, 1999 and the quarter ended March 31, 2000, consisting of LIQUITEK's
balance sheets as of such dates (the "Liquitek Balance Sheets"), the related
statements of profit or loss for the periods then ended, and the respective
notes thereto. Such financial statements (and the notes related thereto) are
herein sometimes collectively referred to as the "Liquitek Financial
Statements." The Liquitek Financial Statements (i) are derived from the books
and records of LIQUITEK, which books and records have been consistently
maintained in a manner which reflects, and such books and records do fairly and
accurately reflect, the assets and liabilities of LIQUITEK, and (ii) fairly
present in all material respects the financial condition of LIQUITEK on the date
of such statements and the results of its operations for the periods indicated,
except as may be disclosed in the notes thereto. Except as and to the extent
reflected or reserved against in the Liquitek Balance Sheets, and as to matters
arising in the ordinary course of its business since the respective date of the
Liquitek Balance Sheets, LIQUITEK has no liability or obligation of a type
required by generally accepted accounting principles to be reflected in the
Liquitek Balance Sheets (whether accrued, to become due, contingent or
otherwise) which individually or in the aggregate could have a materially
adverse effect on the business, assets, condition (financial or otherwise) or
prospects of LIQUITEK. Except as set forth in Exhibit "I," since March 31, 2000,

                                     Page 8
<PAGE>

there has been (a) no declaration, setting aside or payment of any dividend or
other distribution with respect to the Liquitek Shares or redemption, purchase
or other acquisition of any of the Liquitek Shares or any split-up or other
recapitalization relative to any of the Liquitek Shares or any action
authorizing or obligating LIQUITEK to do any of the foregoing, (b) no material
loss, destruction or damage to any material property or asset of LIQUITEK
whether or not insured, (c) no acquisition or disposition of assets (or any
contract or arrangement therefor), or any other transaction by LIQUITEK

material to the business of LIQUITEK, (i) except for ordinary travel advances,
no loans or extensions of credit to stockholders, officers, directors or
employees of LIQUITEK, (j) no agreement to do any of the things described in
this Section 3.6, and (k) no material adverse change in the condition (financial
or otherwise) of LIQUITEK or in its assets, liabilities, properties, business,
or prospects. Except as set forth in the Liquitek Financial Statements or in
Exhibit "I," there are no payments, liabilities, or obligations of any kind due
any of the Liquitek Stockholders or EET Corporation.

         3.7 APPLICABLE PERMITS; COMPLIANCE WITH LAWS. LIQUITEK (i) holds all
licenses, franchises, permits, and authorizations necessary for the lawful
conduct of its business as presently conducted and which the failure to so hold
would have a material adverse effect upon the business, properties, or assets,
or the condition (financial or otherwise) of LIQUITEK, and (ii) has complied
with all applicable statutes, laws, ordinances, rules, and regulations of all
governmental bodies, agencies and subdivisions having, asserting or claiming
jurisdiction over it, which the failure to comply with would have a material
adverse effect upon the business, properties, or assets, or the condition
(financial or otherwise) of LIQUITEK.

         3.8 DISCLOSURE. Neither this Agreement, nor any material certificate,
exhibit, or other written document or statement, furnished to VITRISEAL by or on
behalf of LIQUITEK or, to its knowledge, the Stockholders in connection with the
transactions contemplated by this Agreement contained or contains

                                     Page 9
<PAGE>

any untrue statement of a material fact or omitted or omits to state a material
fact necessary to be stated in order to make the statements contained herein or
therein, when taken as a whole, not misleading. Neither LIQUITEK nor, to its
knowledge, the Stockholders has any knowledge of any fact which has not been
disclosed in writing to VITRISEAL which may reasonably be expected to materially
and adversely affect the business, properties, or assets, or the condition
(financial or otherwise) of LIQUITEK or title of the Stockholders to the
Liquitek Shares or his ability to perform all of the obligations to be performed
by him under this Agreement and/or any other agreement between LIQUITEK, the
Stockholders, and VITRISEAL to be entered into pursuant to any provision of this
Agreement.

         3.9 OWNERSHIP OF LIQUITEK. LIQUITEK issued each Stockholder that number
of Shares set forth opposite the Stockholders' respective names on Exhibit "A,"
which shares, as of the Closing Date, shall constitute issued and outstanding
shares of the capital stock of LIQUITEK. The Shares are duly authorized, validly
issued and outstanding, fully paid and nonassessable and were issued by LIQUITEK
in conformity with all applicable laws.

         3.10 SUBSIDIARIES. LIQUITEK has no subsidiaries and no investments,
directly or indirectly, or other financial interest in any other corporation or
business organization, joint venture or partnership of any kind whatsoever
except as reflected in the Liquitek Financial Statements.

         3.11 REAL PROPERTY. Exhibit "J," attached hereto and incorporated
herein by this reference, contains a complete and accurate legal description or
street address of each parcel of real property owned by, or leased to and
occupied or subleased by LIQUITEK, and LIQUITEK neither owns or leases, nor
occupies, any other real property. The building and all fixtures and
improvements located on such real property are in good operating condition,
ordinary wear and tear excepted. To the best of its knowledge, LIQUITEK is not
in violation of any material zoning, building or safety ordinance, regulation or
requirement, or other law or regulation applicable to the operation of owned or
leased properties, and LIQUITEK has not received any notice of violation with
which its has not complied. All leases of real property to which LIQUITEK is a
party and which are material to the business of LIQUITEK are fully effective in
accordance with their respective terms and afford LIQUITEK peaceful and
undisturbed possession of the subject matter of the lease, and, to the best
knowledge of LIQUITEK, there exists no default on the part of LIQUITEK or
termination thereof.

         3.12 TANGIBLE PERSONAL PROPERTY. Exhibit "K" attached hereto sets forth
a complete list of all items of tangible personal property owned or leased and
used by LIQUITEK in the current conduct of its business, where the original cost
was in excess of $1,000. LIQUITEK has good and marketable title to, or in the
case of leased equipment a valid leasehold interest in, and is in possession of,
all such items of

                                    Page 10
<PAGE>

personal property owned or leased by it, free and clear of all title defects,
mortgages, pledges, security interests conditional sales agreements, liens,
restrictions or encumbrances, the presence of which would result in a material
adverse change in the business, properties, or assets, or the condition
(financial or otherwise) of LIQUITEK. Included in Exhibit "K" is a list of all
outstanding equipment leases and maintenance agreements to which LIQUITEK is a
party as lessee and which individually provide for future lease payments in
excess of $1,000 per month, with the identities of the other parties to all such
leases and agreements shown thereon. All leases of tangible personal property to
which LIQUITEK is a party and which are material to the business of LIQUITEK are
fully effective in accordance with their respective terms, and, to the best
knowledge of LIQUITEK, there exists no default on the part of LIQUITEK or
termination thereof, the presence of which would result in a material adverse
change in the business, properties, or assets, or the condition (financial or
otherwise) of LIQUITEK. Each item of capital equipment reflected in the Liquitek
Balance Sheets which is used in the current conduct of LIQUITEK's business is in
good operating and usable condition and repair, ordinary wear and tear excepted,
and is and will be suitable for use in the ordinary course of LIQUITEK's
business and fit for its intended purposes.

         3.13 TAX MATTERS. LIQUITEK has, since its inception, duly filed all
material federal, state, municipal, local, and other tax returns required to
have been filed by it in those jurisdictions where the nature or conduct of its
business requires such filing and where the failure to so file would be
materially adverse to LIQUITEK. Copies of all such tax returns have been made

<PAGE>

respective dates of the VitriSeal Balance Sheets, VITRISEAL has no liability or
obligation (whether accrued, to become due, contingent or otherwise) which

         4.6 TAX MATTERS. VITRISEAL has, since its inception, accurately
prepared and duly filed all federal, state, county and local tax returns
required to have been filed by it in those jurisdictions where the nature or
conduct of its business requires such filing and where the failure to so file
would be materially adverse to VITRISEAL. Copies of all such tax returns have

department, commission, court, board, bureau, agency or instrumentality,
domestic or foreign, or affecting any of the Stockholders, officers or directors
of VITRISEAL in connection with the business, operations or affairs of
VITRISEAL, which might result in any material adverse change in the business,
properties or assets, or in the condition (financial or otherwise) of VITRISEAL,

any voluntary or involuntary proceeding under applicable bankruptcy laws and has
not made an assignment for the benefit of creditors.

         4.8 COMPLIANCE WITH LAWS. VITRISEAL (i) holds all licenses, franchises,
permits and authorizations necessary for the lawful conduct of its business as
presently conducted and which the failure to so hold would have a material
adverse effect upon the business, properties, or assets, or the condition
(financial or otherwise) of VITRISEAL, and (ii) has complied with all applicable
statutes, laws, ordinances, rules and regulations of all governmental bodies,
agencies and subdivisions having, asserting or claiming jurisdiction over it,
which the failure to comply with would have a material adverse effect upon the
business, properties, or assets, or the condition (financial or otherwise) of
VITRISEAL.

or other written document or statement, furnished to LIQUITEK or the
Stockholders by or on behalf of VITRISEAL in connection with the transactions
contemplated by this Agreement contained or contains any untrue statement of a
material fact or omitted or omits to state a material fact necessary to be
stated in order to make the statements contained herein or therein, when taken

be expected to materially and adversely affect the business, properties,
operations, and/or prospects of VITRISEAL or the ability of VITRISEAL to perform
