Exhibit 10.38

March 28, 2000

Mr. Seth Frielich
P.O. Box 296
Sharon, MA  02067

Dear Seth:

         I hope all is well. In preparation for our public offering, we will be
operating as a business development corporation, which has its own legal
requirements. Accordingly, we will no longer be able to compensate regional
representatives with shares of stock in companies who acquire technologies from
us.

         Instead of the current 10% equity commission upon the consummation of
any successful technology transfer (which results from your efforts), we will
now provide you with a $20,000 cash commission upon the successful sale of a
UTEK licensed technology.

         If you agree to this new commission program, please sign below and fax
back to Carole Mason, CFO, by April 12th, 2000.

         I appreciate all of your efforts to-date and look forward to our
continued mutually beneficial relationship.

Very best regards,

/s/  Uwe

Dear Jerry:

         As we discussed UTEK Corporation would like to engage your services as
an independent marketing representative. Your duties would be to introduce UTEK
to CEO's of public companies for the purpose of having UTEK be engaged by these
companies to find, acquire and transfer technology licenses to them. Your
services will be rendered as an independent contractor and not as an employee of
UTEK. I will provide some assistance to you to help ensure that you can make a
knowledgeable and effective sales presentation.

         We would like you to provide these services on a time available basis,
where you decide how much effort and time you will spend soliciting
prospects/customers for UTEK. You are free to provide these services at a
location of your choice. You must cover your own expenses while providing this
service. However, UTEK will reimburse you for any postage incurred in soliciting
prospects.

         In consideration for providing this service to the company, UTEK will
compensate you with 10% of any monies or stock received from a customer you
introduce to UTEK, within one week following the closing of a technology
transfer agreement between this customer and UTEK.

         The term of this Agreement is 12 months. This Agreement may be
cancelled by either party upon 90 days notice.

         This Agreement is governed by the Laws of the State of Florida.

         If you agree with all of the above terms, please sign and send a copy
of this letter to me. Jerry, I really look forward to working with you again in
the months to come.

Very best regards,

/s/  Clifford

GunnAllen Financial
1715 N. Westshore Blvd, 7th Floor
Tampa, Florida  33607

Dear Chris:

UTEK Corporation would like to engage GunnAllen Financial as an independent
marketing representative. GunnAllen's duties would be to introduce UTEK to CEO's
of public technology companies for the purpose of having UTEK be engaged by
these companies to find, acquire and transfer technology licenses to them.
GunnAllen's services will be rendered as an independent contractor and not as an
employee of UTEK.

We would like your team to provide these services on a time available basis,
where you decide how much effort and time your team will spend providing
introduction to prospective customers for UTEK. Your team is free to provide
these services at a location of their choice.

Upon the consummation of a technology transfer that results from your team's
introduction, UTEK will provide GunnAllen with a 10% commission based on all
consideration received by us for the transaction. This commission will be paid
in like kind i.e., if we receive stock, we will provide 10% of the stock we
receive as a commission. This success fee will be provided within 30 days of the
closing of the transaction.

If UTEK introduces a company to GunnAllen and GunnAllen is engaged by that
company to perform investment banking and/or related services, UTEK will receive
a success fee of 10% on all stock-based compensation received by GunnAllen. UTEK
will also receive 10% on investment banking fees not to include any brokerage
commissions and/or non-accountable expenses received by GunnAllen.

UTEK and GunnAllen Financial agree that each of us shall indemnify and hold
harmless the other with respect to any claims, damages, actions or proceedings,
including expenses related thereto (including reasonable attorney's fees and
expert witness fees) that arise out of, or are related, directly or indirectly,
to our introduction of companies to GunnAllen Financial or your introduction of
companies to us. Each of us agrees that an introduction to the other party does
not imply any endorsement or sponsorship, nor shall such introduction imply that
either of us has conducted due diligence with respect to the Company being
introduced. Any due diligence that either of us has conducted is solely for our
own benefit and, therefore, any due diligence that we or GunnAllen Financial
conduct either prior to or following an introduction shall remain solely the
property of the party conducting such due diligence. The mutual indemnification
agreement is intended to recognize, among other things, that each of us is
responsible for conducting our own due diligence and neither of us is endorsing
or sponsoring a company by introducing a company to the other party.

Dear T.J.,

UTEK Corporation would like to engage Schneider Securities, Inc., specifically,

We would like Keith and Sherry to provide these services on a time available
basis, where you decide how much effort and time they will spend providing
introduction to prospective customers for UTEK. They are free to provide these
services at a location of their choice.

Any introductions that come as a result of attending the recent RIBA conference
are considered to be an introduction by Keith and Sherry and compensation will
be paid as if the introduction was made directly, unless otherwise agreed upon
in writing by Schneider Securities, Inc.

Upon the consummation of a technology transfer that results from their
introduction, UTEK will provide Schneider Securities with a 10% commission based
on all consideration received by us for the transaction. This commission will be
paid in like kind i.e., if we receive stock we will provide 10% of the stock we
receive as a commission. This success fee will be provided within 30 days of the
closing of the transaction.

If UTEK introduces a company to Schneider Securities and Schneider Securities is
engaged by that company to perform investment banking and/or related services,
UTEK will receive a success fee of 10% on all stock-based compensation received
by Schneider Securities. UTEK will also receive 10% on investment banking fees
not to include any brokerage commissions and/or non-accountable expenses
received by Schneider Securities.

UTEK and Schneider Securities agree that each of us shall indemnify and hold
harmless the other with respect to any claims, damages, actions or proceedings,
including expenses related thereto (including reasonable attorney's fees and
expert witness fees) that arise out of, or are related, directly or indirectly,
to our introduction of companies to Schneider Securities or your introduction of
companies to us. Each of us agrees that an introduction to the other party does
not imply any endorsement or sponsorship, nor shall such introduction imply that
either of us has conducted due diligence with respect to the Company being
introduced. Any due diligence that either of us has conducted is solely for our
own benefit and, therefore, any due diligence that we or Schneider Securities
conduct either prior to or following an introduction shall remain solely the
property of the party conducting such due diligence. The mutual indemnification

provision into compliance with such regulations.

construction of this Agreement. Any dispute arising between Schneider and UTEK
Corporation with respect to this Agreement shall be submitted to binding
arbitration in Denver, Colorado, in conformity with the Code of Arbitration
