Refractive Technologies, Inc. shall acquire all 1,000 Shares of common stock of
OptiMetrix Technologies, Inc, which are issued and outstanding at the date of
closing, and in exchange, Advanced Refractive Technologies, Inc shall issue
100,000 shares of series B convertible preferred stock (as described in Exhibit
D), of which UTEK is receiving 98,000 shares and Dr. Irving Bigio is receiving
2,000 shares. At any time after Twelve (12) months from the date of closing,
UTEK shall have the right to convert its series B convertible preferred stock to
common stock of Advanced Refractive Technologies, Inc. to be adjusted to equal
the amount of $1,455,000, based on the previous 10 day average closing price on
the day of conversion. For example, on the date of conversion to common, if the
10 day average closing price is $.10, then UTEK shall receive 14,455,000 shares
of common stock in Advanced Refractive Technologies. Inc. and Dr Bigio shall
receive 450,000 shares of common stock in Advanced Refractive Technologies, Inc.
The common stock that UTEK receives shall be delivered to UTEK within 30 days of
the conversion. Within 30 days of conversion of all of the Shares into Common
Stock, the Company will file a Registration Statement of Form S-1 or Form SB-2
under the Securities Act of 1933 to register the sale of the Conversion Shares
by the Purchasers. The Company shall use its best efforts within reason to
effect the registration, qualification or compliance under the Securities Act
and under other applicable federal law and any applicable securities or "blue
sky" laws of jurisdictions within the United States, of the Conversion Shares
and the Warrant Shares (the "REGISTRABLE SECURITIES"). During the 12 month
period in which Utek is holding said preferred stock, interest shall be charged
at the annual rate of five (5%) percent, compounded quarterly, (at 1.25% per
quarter) payable in cash or in kind due at the date of conversion. If UTEK
receives common stock as payment, the shares must be registered. In addition to
the convertible preferred stock, UTEK shall receive a Warrant attached to the
series B convertible preferred stock for 750,000 shares of common stock of
Advanced Refractive Technologies, Inc. (as described in Exhibit D). The exercise
price of the Warrant shall be equal to fifty (50%) per cent of the price of the
shares established for the conversion of the preferred stock as set forth above.
For example, if the conversion 10 day average closing price is $.10 per share,
the Warrant price shall be $.05 per share. The shares that UTEK will receive
from the conversion and exercise of its Warrant shall be included in a
registration statement filed by Advanced Refractive Technologies, Inc.

                  (b) EXCHANGE OF STOCK. At the Effective Date, by virtue of the
Acquisition, all of the OTI Shares that are issued and outstanding at the

results of its operations on the dates and for the periods shown on such
statements; provided, however, that interim financial statements are subject to
customary year-end adjustments and accruals that, in the aggregate, will not

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 ARFR except as specifically set forth in the ARFR financial

the Closing Date as if they were made on such date. No statement made by it in
this Agreement or in the exhibits to this Agreement or any document delivered by
it or on its 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.

                  (i) COMPLIANCE WITH LAWS. ARFR 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.

                  (j) 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 ARFR, threatened
against ARFR materially affecting its assets or business (financial or
otherwise), and ARFR 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, to the knowledge of ARFR, 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. ARFR has no knowledge of any existing
or threatened occurrence, action or development that could cause a material
adverse affect on ARFR or its business, assets or condition (financial or
otherwise) or prospects.

they may be entitled.

to this Agreement, the parties agree to negotiate in good faith with reasonable
diligence in an effort to resolve the dispute in a mutually acceptable manner.

party against whom the award is rendered or, if in the interest of fairness, as
allocated in accordance with the judgment of the arbitrators. All awards in
arbitration made in good faith and not infected with fraud or other misconduct
shall be final and binding. The arbitrators shall be selected as follows: one by
ARFR, one by UTEK and a third by the two selected arbitrators. The third
arbitrator shall be the chairman of the panel.
