provide for the following:

(a)  The Company shall pay to the Placement Agent a commission of ten percent

to the Placement Agent at the initial Closing and each subsequent closing with

by the Placement Agent exercisable at $8.00 per share for a period of five (5)
years.

(f)  Commencing with the date hereof and for a period of two years thereafter,
regardless of whether this Agreement is sooner terminated, the Company hereby
agrees to afford to Placement Agent the right to act as the Company's
non-exclusive Placement Agent, as the case may be, in any public offering(s) and
private placement(s) to be effectuated by or on behalf of the Company and for
which the Company proposes to utilize the services of an underwriter,
broker-dealer, or Placement Agent, and with such compensation to be determined
on a deal-by-deal basis. Accordingly, if during such period the Company intends
to effectuate a public offering or private placement of the Company's securities
for its benefit, the Company shall promptly notify Placement Agent in writing of
such intention along with the proposed terms of such offering or placement. The
Company shall thereafter promptly furnish Placement Agent with such information
concerning the business, condition and prospects of the Company as Placement
Agent may reasonably request. If within thirty (30) business days of receipt of
such notice of intention, statement of terms and information, TGI finds
comparable financing with the same or better terms and a comparable underwriter,
the Company agrees to utilize TGI as the Placement Agent for such offering.
However, nothing hereunder shall obligate the placement Agent to participate in
any such financing. If TGI brings any private placement financing or secondary
offering to the Company and the terms are acceptable to the company, the Company
will agree to utilize the services of TGI as the Placement Agent for such
transaction and TGI's fees for such will be negotiated on a case by case basis
at that time.

(g)  In the event TGI effectuates a merger, acquisition, joint venture, or
other similar business relationship or business transaction ("Transaction") for
the Company subsequent to the date hereof and or prior to two years from the
date of termination of this Agreement, irrespective of any reason for such
termination, and such Transaction is effectuated as a result or consequence of
any introduction made directly or indirectly by TGI through any third party
introduced by TGI to the Company, or by a person whose introduction to the
Company can be traced back to TGI, during the term of this Agreement, or which
Transaction was initiated, directly or indirectly through any person introduced
by TGI to the Company during the term of this Agreement, then the Company hereby
agrees to pay TGI the following consideration, which payment shall be due and
payable on the date of any such closing with respect thereto:

               10% of the first $2,000,000 of total
               consideration paid in the transaction,
               plus
               8% of the next $2,000,000 of total
               consideration paid in the transaction,
               plus
               6% of the next $2,000,000 of total
               consideration paid in the transaction,
               plus
               4% of the next $2,000,000 of total
               consideration paid in the transaction,
               plus
               2% of the balance of total
               consideration paid in the transaction.

For purposes of this Agreement, "consideration" shall mean the aggregate
consideration paid by the acquirer in connection with the merger, joint venture,
acquisition or divestiture, described herein and shall include all cash, the
principal of any notes executed as part of the purchase price for such
transaction, the value, as determined in good faith by the parties hereto, of
any securities paid or exchanged in connection with the merger, joint venture,
acquisition or divestiture and the amounts of any long-term liabilities, capital
leases, or bank financing of the acquired entity and which are paid or assumed
by the acquiring entity as part of the purchase price for the acquisition. In
the event the Company requests that TGI assists the Company in raising capital
which is not as a result of an introduction made directly or indirectly by TGI
and/or not initiated by TGI, the parties hereto agree that the compensation to
be paid to TGI for said assistance shall be 50% of the above compensation as
incorporated into this agreement.

commencement thereof; and the omission so to notify the indemnifying party will
relieve it from any liability under this Section 10 as to the particular item
for which indemnification is then being sought, but not from any other liability
which it may have to any indemnified party; provided, however, that any failure
by the Placement Agent to notify the Company shall not relieve the Company from
its obligations hereunder, unless the Company is materially prejudiced by such
failure. In case any such action is brought against any indemnified party, and
it notifies an indemnifying party of the commencement thereof, the indemnifying
party will be entitled to participate therein, and to the extent that it may
wish, jointly with any other indemnifying party, similarly notified, to assume
the defense thereof, with counsel who shall be to the reasonable satisfaction of
such indemnified party, and after notice from the indemnifying party to such
indemnified party of its election so to assume the defense thereof, the
indemnifying party will not be liable to such indemnified party under this
Section 10 for any legal or other expenses subsequently incurred by such
indemnified party in connection with the defense thereof other than reasonable
costs of investigation. Any such indemnifying party shall not be liable to any
such indemnified party on account of any settlement of any claim or action
effected without the consent of such indemnifying party.

(d)  Contribution. To provide for just and equitable contribution, if: (i) an
indemnified party makes a claim for indemnification pursuant to Section 10(a) or
10(b) but it is found in a final judicial determination, not subject to further
appeal, that such indemnification may not be enforced in such case, even though
this Agreement expressly provides for indemnification in such case, or (ii) any
indemnified or indemnifying party seeks contribution under the Securities Act,
the Exchange Act, or otherwise, then the Company, on the one hand, and the
Placement Agent, on the other hand, shall contribute to the losses, liabilities,
claims, damages, and expenses whatsoever to which any Placement Agent indemnitee
or Company indemnitee, respectively, may be subject, in such proportions as are
appropriate to reflect the relative benefits received by the Company, on the one
hand, and the Placement Agent, on the other hand; provided, however, that if
applicable law does not permit such allocation, then other relevant equitable
considerations such as the relative fault of the Company and the Placement Agent
in connection with the facts which resulted in such losses, liabilities, claims,
damages, and expenses shall also be considered. The relative benefits received
by the Company, on the one hand, and the Placement Agent, on the other hand,
shall be deemed to be in the same proportion as (x) the total proceeds from the
Offering (net of compensation payable to the Placement Agent pursuant to Section
7 hereof but before deducting expenses) received by the Company, and (y) the
compensation received by the Placement Agent pursuant to Section 7 hereof.

The relative fault, in the case of an untrue statement, alleged untrue
statement, omission, or alleged omission, shall be determined by, among other
things, whether such statement, alleged statement, omission, or alleged omission
relates to information supplied by the Company or by the Placement Agent, and
the parties, relative intent, knowledge, access to information, and opportunity
to correct or prevent such statement, alleged statement, omission, or alleged
omission. The Company and the Placement Agent agree that it would be unjust and
inequitable if the respective obligations of the Company and the Placement Agent
for contribution were determined by pro rata or per capita allocation of the
aggregate losses, liabilities, claims, damages, and expenses or by any other
method of allocation that does not reflect the equitable considerations referred
to in this Section. In no case (except fraud) shall the Placement Agent by
responsible for a portion of the contribution obligation in excess of the
compensation received by it pursuant to Section 7 hereof. No person guilty of a
fraudulent misrepresentation shall be entitled to contribution from any person
who is not guilty of such fraudulent misrepresentation. For purposes of this
Section, each person, if any, who controls the Placement Agent within the
meaning of Section 15 of the Securities Act and each officer, director,
partners, employee, agent, and counsel of the Placement Agent, shall have the
same rights to contribution as the Placement Agent, and each person, if any, who
controls the Company within the meaning of Section 15 of the Securities Act and
each officer, director, employee, agent, and counsel of the Company, shall have
the same rights to contribution as the Company, subject in each case to the
provisions of this Section. Anything in this Section to the contrary
notwithstanding, no party shall be liable for contribution with respect to the
settlement of any claim or action effected without its written consent. This
Section is intended to supersede any right to contribution under the Securities
Act, the Exchange Act, or otherwise

SECTION 11. Registration Rights for Placement Agent's Stock:

The Company shall include in any registration, at its own expense, all of the
underlying Common Stock for the Warrants issued to TGI as compensation as set
forth herein in Section 7(e) provided that if the registration statement
pertains to an underwritten offering, the inclusion of any such shares shall be
subject to an underwriter's cutback if the underwriter determines, in good
faith, that the inclusion of such shares will adversely affect the offering by
the Company with such cutback to be accomplished on a pro-rata basis among all
selling shareholders or as shall be otherwise required by such underwriter.

SECTION 12. Representations and Agreements to Survive Sale and Payment:

Except as the context otherwise requires, all representations, warranties and
agreements contained in this Agreement shall be deemed to be representations,
warranties and agreements at a Closing; and such representations, warranties and
agreements of the Placement Agent and the Company, including the indemnity
agreements contained in Section 10 hereof, shall remain operative and in full
force and effect regardless of any investigation made by you or on your behalf,
or any controlling person, or by or on behalf of the Company, and shall survive
the sale of, and payment for the Shares.

SECTION 13.Notices:

manifested by the portion held invalid or inoperative.

SECTION 16. Counterparts:
