           UT-Battelle, LLC                                         75
                                                                  -----

           Total                                                 1,000

All issued and outstanding MSTI Shares have been duly and validly issued and are
fully paid and non-assessable shares and have not been issued in violation of
any preemptive or other rights of any other person or any applicable laws. MSTI
is not authorized to issue any preferred stock. All dividends on MSTI Shares
which have been declared prior to the date of this Agreement have been paid in

                                       3

<PAGE>

UTEK is a party and will not create a default under any such obligation or under
any agreement to which MSTI or UTEK is a party. This Agreement constitutes a
legal, valid and binding obligation of MSTI, enforceable in accordance with its
terms, except as the enforcement may be limited by bankruptcy, insolvency,
moratorium, or similar laws affecting creditor's rights generally and by the
availability of injunctive relief, specific performance or other equitable
remedies.

         (e) Litigation Relating to this Agreement. There are no suits, actions
or proceedings pending or, to the best of MSTI and UTEK's knowledge, information
and belief without independent inquiry, threatened, which seek to enjoin the
Acquisition or the transactions contemplated by this Agreement or which, if
adversely decided, would have a materially adverse effect on the business,
results of operations, assets or prospects of MSTI, the Technology, Patent
License Agreement, the Consulting Agreement between MSTI and Dr. Thomas Thundat,
a part of Exhibit A attached ("Thundat Consulting Agreement"), or the proposed
Work for Others Agreement between UT-Battelle, LLC and Micro Sensor
Technologies, Inc., a part of Exhibit A attached ("WFO Agreement").

         (f) No Conflicting Agreements. Neither the execution and delivery of
this Agreement nor the fulfillment of or compliance by MSTI or UTEK with the
terms or provisions of this Agreement nor all other documents or agreements
contemplated by this Agreement and the consummation of the transaction
contemplated by this Agreement will result in a breach of the terms, conditions
or provisions of, or constitute a default under, or result in a violation of,
MSTI or UTEK's articles of incorporation or bylaws, the Technology, the Patent
License Agreement, the Consulting Agreement, WFO Agreement or any agreement,
contract, instrument, order, judgment or decree to which MSTI or UTEK is a party
or by which MSTI or UTEK or any of their respective assets is bound, or violate
any provision of any applicable law, rule or regulation or any order, decree,
writ or injunction of any court or government entity which materially affects
their respective assets or businesses.

         (g) Consents. No consent from or approval of any court, governmental
entity or any other person is necessary in connection with execution and
delivery of this Agreement by MSTI and UTEK or performance of the obligations of
MSTI and UTEK hereunder or under any other agreement to which MSTI or UTEK is a
party; and the consummation of the transactions contemplated by this Agreement
will not require the approval of any entity or person in order to prevent the
termination of the Technology, the Patent License Agreement, Thundat Consulting
Agreement, WFO Agreement or any other material right, privilege, license or
agreement relating to MSTI or its assets or business.

         (h) Title to Assets. MSTI has or has agreed to enter into the following
agreements, as listed on Exhibit A attached:

(1)      Patent License Agreement;

(2)      WFO Agreement;

                                       4
<PAGE>

(3)      Thundat Consulting Agreement.

These agreements and the assets shown on the balance sheet of attached Exhibit B
are the sole assets of MSTI. MSTI has or will by Closing Date have good and
marketable title to its assets, free and clear of all liens, claims, charges,
mortgages, options, security agreements and other encumbrances of every kind or
nature whatsoever.

         (i)      Intellectual Property

         (1)      UT-Battelle owns the Technology. UT-Battelle has all right,
         power, authority and ownership and entitlement to file, prosecute and
         maintain in effect the Technology;

         (2)      The Technology was invented by Thomas Thundat, Ph.D. and Eric
         Wachter ("Inventors"). The Inventors, as well as Oak Ridge National
         Laboratory, have assigned all of their rights, title and interests in
         the Technology to UT-Battelle;

         (3)      The Patent License Agreement sets forth a description of all
         of MSTI's right, title and interest in and to all intellectual property
         rights in the Technology, including but not limited to, inventions
         (whether patentable or not), discoveries, trade secrets, technology,
         technical information, proprietary information, processes, know-how,
         designs, United States and foreign patents and patent applications (and
         all reissues, divisions, renewals, extensions, provisionals,
         continuations, and continuations-in-part of this Agreement), trade
         names, logos, trademarks, service marks, trademark and service marks
         registrations, copyrights, copyright registrations, and all computer
         software, data and databases owned by or licensed to MSTI (collectively
         "Intellectual Property"). MSTI has or will have by the Closing Date,
         good and exclusive and non-exclusive licensee interests to the
         Intellectual Property free and clear of all liens, claims, conditions,
         charges, equitable interests, or other encumbrances or restrictions,
         with the exception of those outlined in the Patent License Agreement
         between MSTI and UT-Battelle. To the best of MSTI's and UTEK's
         knowledge, MSTI has not infringed nor is infringing any intellectual
         property owned or used by another person or entity. MSTI and UTEK
         further state that to the best of their knowledge and without
         conducting an infringement investigation they are unaware of any
         infringement of the Technology and Intellectual Property on any other
         party's technology or intellectual property. To the best of MSTI and
         UTEK's knowledge, information and belief, there are no pending or
         threatened actions against MSTI or UTEK for infringement of any third
         party's intellectual property. Neither MSTI nor UTEK has received any
         claim or notice that their Intellectual Property infringes upon the
         rights of any third party. The Patent License Agreement is in full
         force and effect and following the consummation of the transactions
         contemplated by this Agreement shall remain in full force and effect
         and is a legal, valid, binding and enforceable in accordance with their
         respective terms. Except as disclosed in Exhibit A attached, MSTI is
         not a party to any other license (in or out) with respect to the

                                       5

<PAGE>

         Intellectual Property. Except as set forth in the attached schedules
         and exhibits, neither MSTI nor UTEK is a party to any agreement that
         imparts or has imparted an obligation of non-competition, secrecy,
         confidentiality or non-disclosure upon MSTI. MSTI is or was not under
         any obligation of non-competition, secrecy, confidentiality or
         non-disclosure to any third party.

         (4) Except as otherwise set forth in this Agreement, SENSE acknowledges
         and understands that MSTI and UTEK make no other representations and
         provides no assurances that the rights to the Technology and
         Intellectual Property contained in the Patent License Agreement do not,
         and will not in the future, infringe or otherwise violate the rights of
         third parties, and

         (5) Except as otherwise expressly set forth in this Agreement, MSTI and
         UTEK makes no representations and extends no warranties of any kind,
         either express or implied, including, but not limited to warranties of
         merchantability, fitness for a particular purpose, non-infringement and
         validity of the Intellectual Property.

         (j) Liabilities of MSTI. MSTI has no assets, no liabilities or
obligations of any kind, character or description except those listed on the
attached schedules and exhibits.

         (k) Financial Statements. The unaudited financial statements of MSTI,
including a balance sheet, attached as Exhibit B and made a part of this
Agreement, are, in all respects, complete and correct and present fairly MSTI's
financial position and the results of its operations on the dates and for the
periods shown in this Agreement; provided, however, that interim financial
statements are subject to customary year-end adjustments and accruals that, in
the aggregate, will not have a material adverse effect on the overall financial
condition or results of its operations. MSTI has not engaged in any business not
reflected in its financial statements. There have been no material adverse
changes in the nature of its business, prospects, the value of assets or the
financial condition since the date of its financial statements. There are no,
and on the Closing Date there will be no, outstanding obligations or liabilities
of MSTI except as specifically set forth in the financial statements and the
other attached schedules and exhibits. There is currently no information known
to MSTI or UTEK that would prevent the financial statements of MSTI from being
audited in accordance with generally accepted accounting principles.

         (l) Taxes. All returns, reports, statements and other similar filings
required to be filed by MSTI with respect to any federal, state, local or
foreign taxes, assessments, interests, penalties, deficiencies, fees and other
governmental charges or impositions have been timely filed with the appropriate
governmental agencies in all jurisdictions in which such tax returns and other
related filings are required to be filed; all such tax returns properly reflect
all liabilities of MSTI for taxes for the periods, property or events covered by
this Agreement; and all taxes, whether or not reflected on those tax returns,

                                       6

<PAGE>

and all taxes claimed to be due from MSTI by any taxing authority, have been
properly paid, except to the extent reflected on MSTI's financial statements,
where MSTI has contested in good faith by appropriate proceedings and reserves
have been established on its financial statements to the full extent if the
contest is adversely decided against it. MSTI has not received any notice of
assessment or proposed assessment in connection with any tax returns, nor is
MSTI a party to or to the best of its knowledge, expected to become a party to
any pending or threatened action or proceeding, assessment or collection of
taxes. MSTI has not extended or waived the application of any statute of
limitations of any jurisdiction regarding the assessment or collection of any
taxes. There are no tax liens (other than any lien which arises by operation of
law for current taxes not yet due and payable) on any of its assets. There is no
basis for any additional assessment of taxes, interest or penalties. MSTI has
made all deposits required by law to be made with respect to employees'
withholding and other employment taxes, including without limitation the portion
of such deposits relating to taxes imposed upon MSTI. MSTI is not and has never
been a party to any tax sharing agreements with any other person or entity.

         (m) Absence of Certain Changes or Events. From May 21, 2001 until the
Closing Date, MSTI has not, and without the written consent of SENSE, it will
not have:

         (1) Sold, encumbered, assigned let lapsed or transferred any of its
         material assets, including without limitation the Intellectual
         Property, the Patent License Agreement or any other material asset;

         (2) Amended or terminated the Patent License Agreement or other
         material agreement or done any act or omitted to do any act which would
         cause the breach of the Patent License Agreement or any other material
         agreement;

         (3) Suffered any damage, destruction or loss whether or not in control
         of MSTI;

         (4) Made any commitments or agreements for capital expenditures or
         otherwise;

         (5) Entered into any transaction or made any commitment not disclosed
         to SENSE;

         (6) Incurred any material obligation or liability for borrowed money;

         (7) Suffered any other event of any character, which is reasonable
         to expect, would adversely affect the future condition (financial or
         otherwise) assets or liabilities or business of MSTI; or

         (8) Taken any action which could reasonably be foreseen to make any of
         the representations or warranties made by MSTI or UTEK untrue as of the
         date of this Agreement or as of the Closing Date.

                                       7

complete list of all contemplated and executed agreements between MSTI and a
third party. A complete and accurate copies of all material agreements,
contracts and commitments of the following types, whether written or oral to
which it is a party or is bound ("Contracts"), has been provided to SENSE and
such agreements are or will be at the Closing Date, in full force and effect
without modifications or amendment and constitute the legally valid and binding

which would, if adversely determined, individually or in the aggregate,

Acquisition or the transactions contemplated by this Agreement or which, if
adversely decided, would have a materially adverse effect on its business,
results of operations, assets, prospects or the results of its operations of
SENSE.

         (f) No Conflicting Agreements. Neither the execution and delivery of
this Agreement nor the fulfillment of or compliance by SENSE with the terms or
provisions of this Agreement will result in a breach of the terms, conditions or
provisions of, or constitute a default under, or result in a violation of, their
respective corporate charters or bylaws, or any agreement, contract, instrument,
order, judgment or decree to which it is a party or by which it or any of its

regulation or any order, decree, writ or injunction of any court or governmental
entity which materially affects its assets or business.

representations, no consent from or approval of any court, governmental entity
or any other person is necessary in connection with its execution and delivery
of this Agreement; and the consummation of the transactions contemplated by this
Agreement will not require the approval of any entity or person in order to
prevent the termination of any material right, privilege, license or agreement

         (h) Financial Statements. The unaudited financial statements of SENSE
attached as Exhibit C present fairly its financial position and the results of
its operations on the dates and for the periods shown in this Agreement;
provided, however, that interim financial statements are subject to customary
year-end adjustments and accruals that, in the aggregate, will not have a
material adverse effect on the overall financial condition or results of its
operations. SENSE has not engaged in any business not reflected in its financial
statements. There have been no material adverse changes in the nature of its
business, prospects, the value of assets or the financial condition since the
date of its financial statements. There are no outstanding obligations or
liabilities of SENSE except as specifically set forth in the SENSE financial
statements.

         (i) Full Disclosure. All representations or warranties of SENSE are
true, correct and complete in all material respects on the date of this
Agreement and shall be true, correct and complete in all material respects as of
the Closing Date as if they were made on such date. No statement made by them in
this Agreement or in the exhibits to this Agreement or any document delivered by
them or on their behalf pursuant to this Agreement contains an untrue statement
of material fact or omits to state all material facts necessary to make the
statements in this Agreement not misleading in any material respect in light of
the circumstances in which they were made.

         (j) Compliance with Laws. SENSE is in compliance with all applicable
laws, rules, regulations and orders promulgated by any federal, state or local
government body or agency relating to its business and operations.

         (k) Litigation. There is no suit, action or any arbitration,
administrative, legal or other proceeding of any kind or character, or any
governmental investigation pending or, to the best knowledge of SENSE,
threatened against SENSE materially affecting its assets or business (financial
or otherwise), and SENSE is not in violation of or in default with respect to
any judgment, order, decree or other finding of any court or government
authority. There are no pending or threatened actions or proceedings before any
court, arbitrator or administrative agency, which would, if adversely
determined, individually or in the aggregate, materially and adversely affect
its assets or business of SENSE or the transactions contemplated hereby.

         (l) SENSE has no knowledge of any existing or threatened occurrence,
action or development that could cause a material adverse effect on SENSE or its
business, assets or condition (financial or otherwise) or prospects, except as
otherwise set forth in the SENSE SEC Documents and PPM (as hereinafter defined).

        2.03 Investment Representations of UTEK. UTEK represents and warrants to
SENSE that:

                                     11
<PAGE>

         (a) General. It has such knowledge and experience in financial and
business matters as to be capable of evaluating the risks and merits of an
investment in SENSE Shares pursuant to the Acquisition. It is able to bear the
economic risk of the investment in SENSE Shares, including the risk of a total
loss of the investment in SENSE Shares. The acquisition of SENSE Shares is for
its own account and is for investment and not with a view to the distribution
thereof. Except a permitted by law, it has a no present intention of selling,
transferring or otherwise disposing in any way of all or any portion of the
shares at the present time. All information that it has supplied to SENSE is
true and correct. It has conducted all investigations and due diligence
concerning SENSE to evaluate the risks inherent in accepting and holding the
shares which it deems appropriate, and it has found all such information
obtained fully acceptable. It has had an opportunity to ask questions of the
officers and directors of SENSE concerning SENSE Shares and the business and
financial condition of and prospects for SENSE, and the officers and directors
of SENSE have adequately answered all questions asked and made all relevant
information available to them. UTEK is an "accredited investor," as the term is
defined in Regulation D, promulgated under the Securities Act of 1933, as
amended, and the rules and regulations thereunder.

         (b) Stock Transfer Restrictions.

         UTEK acknowledges that the SENSE Shares will not be registered and UTEK
will not be permitted to sell or otherwise transfer the SENSE Shares in any
transaction in contravention of the following legend, which will be imprinted in
substantially the follow form on the stock certificate representing SENSE
Shares:

         THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
         UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT'), OR UNDER THE
         SECURITIES LAWS OF ANY STATE. THESE SECURITIES MAY NOT BE SOLD, OFFERED
         FOR SALE, ASSIGNED, TRANSFERRED OR OTHERWISE DISPOSED OF UNLESS
         REGISTERED PURSUANT TO THE PROVISION OF THE ACT AND THE LAWS OF SUCH
         STATES UNDER WHOSE LAWS A TRANSFER OF SECURITIES WOULD BE SUBJECT TO A
         REGISTRATION REQUIREMENT, UNLESS UTEK CORPORATION HAS OBTAINED AN
         OPINION OF COUNSEL SATISFACTORY TO SENSE STATING THAT SUCH DISPOSITION
         IS IN COMPLIANCE WITH AN AVAILABLE EXEMPTION FROM SUCH REGISTRATION.

         (c)      SENSE SEC Documents.

         SENSE has previously delivered to UTEK copies of SENSE's Annual Report
on Form 10-KSB for the year ended December 31, 2000 and its Quarterly Report on
Form 10-QSB for the quarter ended March 31, 2001 (the "SENSE SEC Documents"), as
well as a copy of SENSE's Confidential Private Placement Memorandum dated
January 29, 2001 ("PPM"). UTEK acknowledges receipt of the SENSE SEC Documents
and PPM and that (i) the SENSE SEC Documents and the PPM contain material

                                       12

<PAGE>

information about SENSE and its business, operations and financial condition,
(ii) acquisition of the SENSE Shares is speculative and involves numerous risks
and uncertainties which are described in the SENSE SEC Documents and the PPM and
(iii) a review of the SENSE SEC Documents, the PPM and the documents and other
reports filed by SENSE with the Securities and Exchange Commission ("SEC") would
provide UTEK with information that is meaningful and significant in evaluating
the risks and merits of acquiring the SENSE Shares. UTEK further acknowledged
that the SENSE SEC Documents and other reports and documents filed by SENSE are
available for review and downloading at the SEC's Web site at and that copies
thereof will be furnished to UTEK upon request to SENSE.

              Year                                           Price
              ----                                        ----------
              2004                                         104.250%

the Notes to be redeemed on a pro rata basis, by lot or by such other method as
the Trustee in its sole discretion shall deem to be fair and appropriate.

     Notes in denominations larger than $1,000 may be redeemed in part.  On and
after the redemption date interest ceases to accrue on Notes or portions of them

of such Note at the redemption price together with accrued interest, interest
shall continue to accrue at the rate borne by the Notes.

repurchase, as provided in, and subject to the terms of, the Indenture. In

interest to the date of purchase, as provided in, and subject to the terms of,
the Indenture.

     7.  Denominations, Transfer, Exchange.  If the Notes are issued in global
         ---------------------------------
form, and this Note contains a legend in the face hereof to such effect, the
provisions of this Section 7 shall be deemed superseded by such legend and
Section 3.02(c) of the First Supplemental Indenture, to the extent the
provisions of this Section 7 are inconsistent with such legend or Section
3.02(c).

     The Notes are in registered form without coupons in denominations of $1,000
and integral multiples of $1,000.  A Holder may transfer or exchange Notes by
presentation of such Notes to the Registrar or a co-Registrar with a request to
register the transfer or to exchange them for an equal principal amount of Notes
of other denominations.  The Registrar may require a Holder, among other things,
to furnish appropriate endorsements and transfer documents and to

                                                                   (Senior Note)

pay any taxes and fees required by law or permitted by the Indenture. The

treated as the owner of it for all purposes.

     9.  Unclaimed Money.  If money for the payment of principal or interest
         ---------------
remains unclaimed for two years, the Trustee or Paying Agent will pay the money
back to the Company at its request. After that, Holders entitled to the money
must look to the Company for payment unless an abandoned property law designates
another person.

    10.  Amendment, Supplement, Waiver.  Subject to certain exceptions, the
         -----------------------------
Indenture or the Notes may be amended or supplemented with the consent of the
Holders of at least a majority in principal amount of the outstanding Notes of
each Series affected by the amendment, and any past default or compliance with
any provision relating to any Series of the Notes may be waived in a particular
instance with the consent of the Holders of a majority in principal amount of
the outstanding Notes of such Series.  Without the consent of any
Securityholder, the Company and the Trustee may amend or supplement the
Indenture or the Notes to cure any ambiguity, defect or inconsistency, to
provide for uncertificated Notes in addition to or in place of certificated
Notes, to create a Series and establish its terms or to make any other change,
provided such action does not adversely affect the rights of any Securityholder.

    11.  Defaults and Remedies.  The following are Events of Default:
         ---------------------
(i) failure by the Company to pay interest on the Notes when due which default
continues for a period of 30 days or the principal of the Notes when due; (ii)
failure by the Company to perform any other covenant in the Notes or the
Indenture for 60 days after receipt by the Company of a notice of such Default;
(iii) default under any mortgage, indenture (including the Indenture) or
instrument under which is issued or which secures or evidences Indebtedness of
the Company or any Restricted Subsidiary (other than Non-Recourse Indebtedness)
which default constitutes a failure to pay principal of such Indebtedness in an
amount of $20,000,000 or more when due and payable (other than as a result of
acceleration) or results in Indebtedness (other than Non-Recourse Indebtedness)
in the aggregate of $20,000,000 or more becoming or being declared due and
payable before it would otherwise become due and payable; (iv) entry of a final
judgment for the payment of money against the Company or any Restricted
Subsidiary in an amount of $5,000,000 or more which remains undischarged or
unstayed for a period of 60 days after the date on which the right to appeal
such judgment has expired or become subject to an enforcement proceeding; or (v)
certain events of bankruptcy or insolvency.

     In case an Event of Default (other than arising out of certain events of
bankruptcy or insolvency) occurs and is continuing, the Trustee or the Holders
of at least 25% in aggregate principal amount of the Notes at the time
outstanding, by notice in writing to the Company (and to the Trustee if given by
the Holders), may declare to be due and payable immediately that portion of the
principal amount of the Notes at the time outstanding and accrued and unpaid
interest if any, to the date of acceleration and upon such declaration the same
shall become and be immediately due and payable.  In case an Event of Default
arising out of certain events of

                                                                   (Senior Note)

                                       4
<PAGE>

bankruptcy or insolvency occurs and is continuing, the outstanding principal of
and accrued and unpaid interest if any, on the Notes shall become and be
immediately due and payable without any declaration or other act on the part of
the Trustee or any of the Holders.

     Such declaration or acceleration and its consequences may be rescinded by
Holders of a majority in aggregate principal amount of Notes at the time
outstanding if all existing Events of Default have been cured or waived (except
non-payment of principal that has become due solely because of the acceleration)
and if the rescission would not conflict with any judgment or decree.

     An existing Default (other than a default in payment of principal of or
interest on the Notes or default with respect to a provision which cannot be
modified under the terms of the Indenture without the consent of each
Securityholder affected) may be waived by the Holders of a majority in aggregate
principal amount of Notes at the time outstanding upon the conditions provided
in the Indenture.

    12.  Successor Corporation.  When a successor corporation assumes all the
         ---------------------
obligations of its predecessor under the Notes and the Indenture, the
predecessor corporation will be released from those obligations.

    13.  Trustee Dealings With Company.  Bank One Trust Company, N.A. (as
         -----------------------------
successor in interest to The First National Bank of Chicago), the Trustee under
the Indenture, in its individual or any other capacity, may make loans to,
accept deposits from, and perform services for the Company or its affiliates,
and may otherwise deal with the Company or its affiliates, as if it were not
Trustee.

    14.  No Recourse Against Others.  A director, officer, employee or
         --------------------------
stockholder, as such, of the Company shall not have any liability for any
obligations of the Company under the Notes or the Indenture or for any claim
based on, in respect of or by reason of, such obligations or their creation.
Each Securityholder by accepting a Note waives and releases all such liability.
The waiver and release are part of the consideration for the issue of the Notes.

    15.  Discharge of Indenture.  The Indenture contains certain provisions
         ----------------------
pertaining to defeasance, which provisions shall for all purposes have the same
effect as if set forth herein.

    16.  Authentication.  This Note shall not be valid until the Trustee signs
         --------------
the certificate of authentication on the other side of this Note.

    17.  Abbreviations.  Customary abbreviations may be used in the name of a
         -------------
