untrue statement of a material fact, or omit to state any material fact
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading, or if it is necessary at any time after
the date hereof to amend or supplement the Offering Documents to comply with the
Act or the applicable Rules and Regulations, the Company shall forthwith notify
the Agent thereof and shall prepare such further amendment or supplement to the
Offering Documents as may be required and shall furnish and deliver to the Agent
and to others, whose names and addresses are designated by the Agent, all at the

signed subscription documents, those subscribers have been approved by the
Company and all other Closing conditions have been met, Escrow Agent shall

          --------------------

          (a)  A commission of six percent (6.0%) of the gross subscription
     proceeds of the Initial Offering and any subsequent Offerings; and

          (b)  In addition to the fees and reimbursement of costs set forth in
     Section 3.5 of this Agreement, the Company shall issue to the Agent six

                                       4
<PAGE>

     Shares"). The Agent shares shall have piggy-back registration rights. The

     4.  Offering of the Securities on Behalf of the Company.
         ---------------------------------------------------

     4.1  In offering the Securities for sale, the Agent shall offer them solely
as an agent for the Company, and such offer shall be made upon the terms and
subject to the conditions set forth in the Offering Documents. The Agent shall
commence making such offer as an agent for the Company as soon as possible
following delivery of the Offering Documents.

     4.2  The Agent will not make offers to sell the Securities to, or solicit
offers to subscribe for any Securities from, persons or entities that are not
"accredited investors" as defined in Regulation D.

     4.3  The Agent shall make offers and sales of the securities only in such
jurisdictions where it is permitted to do so in accordance with applicable law.

     5.   Right of First Refusal.  The Company hereby grants Agent rights
          ----------------------
of first refusal as follows:

    5.1  Beginning the date hereof and ending 90 days from the final Closing,
the Company grants to the Agent a right of first refusal to act as the Company's
exclusive placement agent for the sale of any debt or equity to be issued by the
Company ("Financing Transaction"). The Agent shall have five (5) business days
from the date of its receipt from the Company of a detailed and complete summary
of any proposed Financing Transaction to exercise its right of first refusal to
act as Agent upon the same terms and conditions on an all or nothing basis. In
the event that the Company materially changes or deviates from any of the terms
of the proposed Financing Transaction contained in such written notice, then
such changes or deviation shall be deemed to constitute a new proposed Financing
Transaction and the Company shall be required to submit a new written right of
first refusal notice to Agent and Agent shall have five (5) business days from
the date of such notice to exercise its right of first refusal as described
herein.

     5.2  The Company agrees to maintain the confidentiality of the Agent's
clients, except as required by applicable law. Such clients shall be those
entities which invest in the Offering (the "Clients"). For a period of two years
from the Closing (the "Exclusivity Period"), the Company will not solicit or
enter into any financing transaction ("Transaction") with the clients without
the written consent of Agent and payment to the Agent of like compensation as
the compensation described herein.

     5.3  In the event that Company breaches Section 5.2 of this Agreement and
engages in a Transaction with the Clients during the Exclusivity Period or
breaches Section 5.1 of this Agreement, Agent shall be entitled to receive
compensation in the same proportion to the financing done without Agent's
participation as the compensation to Agent under this Agreement bears to the
financing raised in this Offering.

     6(a) Covenants of the Company.  The Company covenants and agrees with
          ------------------------
the Agent that:

                                       5
<PAGE>

     6.1  As a condition precedent to the Initial Closing, the Company will
deliver to the Agent a true and correct copy of the Articles of Incorporation of
the Company, and all amendments and certificates of designation of preferences
of preferred stock, including without limitation the certificate of designation
of preferences regarding the Securities, if applicable, certified by the
Secretary of State of Delaware.

     6.2  Prior to the Closing Date, the Company will cooperate with the Agent
          in such investigation as it may make or cause to be made of all of the
          properties, business and operations of the Company in connection with
          the Offering of the Securities. The Company will make available to it
          in connection therewith such information in its possession as the
          Agent may reasonably request and will make available to the Agent such
          persons as the Agent shall deem reasonably necessary and appropriate
          in order to verify or substantiate any such information so supplied,
          subject to the limitations arising pursuant to the federal securities
          laws.

     7.   Indemnification.
          ---------------

     7.1  The Company agrees to indemnify and hold harmless the Agent, each
person who controls the Agent within the meaning of Section 15 of the Act or
Section 20 of the Securities Exchange Act of 1934, as amended, and the Agent's
employees, accountants, attorneys and agents (the "Agent's Indemnitees") against
any and all losses, claims, damages or liabilities, joint or several, to which
they or any of them may become subject under the Act or any other statute or at
common law for any legal or other expenses (including the costs of any
investigation and preparation) incurred by them in connection with any
litigation, whether or not resulting in any liability, but only insofar as such
losses, claims, damages, liabilities and litigation arise out of or are based
upon any untrue statement of material fact contained in the Offering Documents
or any amendment or supplement thereto or the omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein, under the circumstances under which they were made, not misleading, all
as of the date of the Offering Documents or of such amendment as the case may
be; provided, however, that the indemnity agreement contained in this Section
    --------
7.1 shall not apply to amounts paid in settlement of any such litigation, if
such settlements are made without the consent of the Company, nor shall it apply
to the Agent's Indemnitees in respect to any such losses, claims, damages or
liabilities arising out of or based upon any such untrue statement or alleged
untrue statement or any such omission or alleged omission, if such statement or
omission was made in reliance upon information furnished in writing to the
Company by the Agent specifically for use in connection with the preparation of
the Offering Documents or any such amendment or supplement thereto.  This
indemnity agreement is in addition to any other liability which the Company may
otherwise have to the Agent's Indemnitees.  The Agent's Indemnitees agree,
within a reasonable time after the receipt by them of written notice of the
commencement of any action against them in respect to which indemnity may be
sought from the Company under this Section 7.1, to notify the Company in
writing of the commencement of such action, and if the Agent's Indemnitees shall
notify the Company of the commencement thereof, the Company shall be entitled to
participate in (and, to the extent that the Company shall wish, to direct) the
defense thereof at its own expense, but such defense shall be conducted by
counsel of recognized standing and reasonably satisfactory to the Agent's
Indemnitees, defendant or defendants, in such litigation.  The Company agrees to
notify the Agent's Indemnitees promptly of the commencement of any litigation or
proceedings against the Company or any of the Company's officers or directors of
which the Company may be advised in connection with the issue and sale of any of
the Securities and to furnish to the Agent's Indemnitees, at their request,
copies of all pleadings therein and to permit the Agent's Indemnities to be
observers therein and apprise the Agent's Indemnitees of all developments
therein, all at the Company's expense.

     7.2  The Agent agrees, in the same manner and to the same extent as set
forth in Section 7.1 above, to indemnify and hold harmless the Company, and the
Company's employees, accountants,

                                       6
<PAGE>

attorneys and agents (the "Company's Indemnitees") with respect to (i) any
statement in or omission from the Offering Documents or any amendment or
supplement thereto or any application or any information furnished pursuant to
Section 3.4 hereof, if such statement or omission was made in reliance upon
information furnished in writing to the Company by the Agent or on its behalf
specifically for use in connection with the preparation thereof or supplement
thereto, or (ii) any untrue statement of a material fact made by the Agent or
its agents not based on statements in the Offering Documents or authorized in
writing by the Company, or with respect to any misleading statement made by the
Agent or its agents resulting from the omission of material facts which
misleading statement is not based upon the Offering Documents, or information
furnished in writing by the Company or, (iii) any breach of any representation,
warranty or covenant made by the Agent in this Agreement. The Agent shall not be
liable for amounts paid in settlement of any such litigation if such settlement
was effected without its consent. In case of the commencement of any action in
respect of which indemnity may be sought from the Agent, the Company's
Indemnitees shall have the same obligation to give notice as set forth in
Section 7.1 above, subject to the same loss of indemnity in the event such
notice is not given, and the Agent shall have the same right to participate in
(and, to the extent that it shall wish, to direct) the defense of such action at
its own expense, but such defense shall be conducted by counsel of recognized
standing reasonably satisfactory to the Company. The Agent agrees to notify the
Company's Indemnitees and, at their request, to provide copies of all pleadings
therein and to permit the Company's Indemnitees to be observers therein and
apprise them of all the developments therein, all at the Agent's expense.

     7.3  If for any reason the indemnity provided for in Section 7.1 or 7.2 is
unavailable to an Indemnified Person or insufficient to hold an Indemnified
Person harmless, then the Indemnifying Party, to the fullest extent permitted by
law, shall contribute to the amount paid or payable by such Indemnified Person
as a result of such claims, liabilities, losses, damages or expenses in such
proportion as is appropriate to reflect the relative benefits received by the
Company on one hand and by the Agent on the other, from the transaction or
proposed transaction under this Agreement or if allocation on that basis is not
permitted under applicable law, in such proportion as is appropriate to reflect
not only the relative benefits received by the Company on the one hand and the
Agent on the other, but also the relative fault of the Company and the Agent, as
well as any relevant equitable considerations.  It is hereby further agreed that
the relative benefits to the Company on the one hand and the Agent on the other
with respect to any transaction contemplated by this Agreement shall be deemed
to be paid in the same proportion as (i) the total value of the transaction
bears to (ii) the fees paid to the Agent with respect to the transaction.  The
relative fault of the Company on the one hand and the Agent on the other with
respect to the transaction shall be determined by reference to, among other
things, whether any untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Company or by the Agent and the parties relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission.  The indemnity, contribution and expense reimbursement
obligations set forth herein (i) shall be in addition to any liability an
Indemnifying Party may have to any Indemnified Person at common law of
otherwise, (ii) shall survive the termination of this Agreement, (iii) shall
apply to any modification of this Agreement and shall remain in full force and
effect following the completion or termination of the Agreement, (iv) shall
remain operative and in full force and effect regardless of any investigation
made by or on behalf of the Agent or any other Indemnified Person, and (v) shall
be binding on any successor or assign of the Company or the Agent and the
respective successors or assigns to all or substantially all of the Company's or
the Agent's business and assets.

liabilities or obligations (direct or contingent) or disposed of any assets, or

substantially adverse change in its condition, financial or otherwise.  At the

have furnished such counsel such documents as he may have requested to enable

     10.  Termination.
          -----------

     10.1 This Agreement may be terminated by the Agent by notice to the Company
in the event that the Company shall have failed or been unable to comply with
any of the terms, conditions or provisions of this Agreement on the part of the
Company to be performed, complied with or fulfilled within the respective times,
if any, herein provided for, unless compliance therewith or performance or
satisfaction thereof shall have been expressly waived by the Agent in writing.

     10.2 This Agreement may be terminated by the Company by notice to the Agent
in the event that the Agent shall have failed or been unable to comply with any
of the terms, conditions or provisions of this Agreement on the part of the
Agent to be performed, complied with or fulfilled within the respective times,
if any, herein provided for, unless compliance therewith or performance or
satisfaction thereof shall have been expressly waived by the Company in writing.

     10.3 This Agreement may be terminated by the Agent by notice to the Company
at any time, if, in the reasonable, good faith judgment of the Agent, payment
for and delivery of the Securities is rendered impracticable or inadvisable
because: (i) additional material governmental restrictions not in force and
effect on the date hereof shall have been imposed upon trading in securities
generally; (ii) a war or other national calamity shall have occurred; or (iii)
the condition of the market (either generally or with reference to the sale of
the Securities to be offered hereby other than the delisting of the Company's
shares on the Nasdaq SmallCap Market) or the condition of any matter affecting
the Company or any other circumstance is such that it would be undesirable,
impracticable or inadvisable, in the judgment of the Agent, to proceed with this
Agreement or with the Offering.

     10.4 Any termination of this Agreement pursuant to this Section shall be
without liability of any character (including, but not limited to, loss of
anticipated profits or consequential damages) on the part of any party thereto,
except that the Company shall remain obligated to pay the costs and expenses
provided to be paid by it specified in Sections 3.5; and the Company and the
Agent shall be obligated to pay, respectively, all losses, claims, damages or
liabilities, joint or several, under Section 7.1 in the case of the Company and
Section 7.2 in the case of the Agent.

     11.  Agent's Representations, Warranties and Covenants.  The Agent
          -------------------------------------------------
represents and warrants to and agrees with the Company that:

     11.1 Agent is a corporation duly incorporated and existing under the laws
of the state of Georgia.  Agent is registered with the Securities Exchange
Commission and the NASD and is authorized to receive the compensation from the
Company provided hereunder.

     11.2 All corporate actions by Agent required for the execution, delivery
and performance of this Agreement have been taken.  The execution and delivery
of this Agreement by the Agent, the observance and performance thereof, and the
consummation of the transactions contemplated herein or in the Memorandum do not
and will not constitute a material breach of, or a material default under, any
instrument or agreement by which the Agent is bound, and does not and will not,
to the best of the Agent's knowledge, contravene any existing law, decree or
order applicable to it.  This Agreement constitutes a valid and binding
agreement of Agent, enforceable in accordance with its terms.

     11.3 Agent understands that the Company is relying upon Agent's
representations and warranties in connection with the Offering and the sale of
the Securities contemplated by this Agreement.

     11.4 Agent's representations and warranties under this Section shall be
true and correct as of each Closing, and shall survive each Closing for a period
of six months.

     11.5 No Short Sales of the Common Stock.  The Agent shall not directly or
          ----------------------------------
indirectly engage in any short sales or third party short sales of the Company's
Common Stock or hold a "put equivalent position" with respect to the Common
Stock (as defined in Rule 16a-1 under the 1934 Act).  Notwithstanding anything
contained to the contrary in this section, in the event that the Company enters
into a private placement transaction (other than in connection with employee
benefit plans, employee or consultant compensation, or in connection with
mergers and acquisitions) which permits the investors rights to engage in short
sales of Common Stock, the restrictions contained in this section shall be
automatically modified to permit the Agent to engage in short sales of Common
Stock substantially to the extent permitted by the Company with respect to such
private placement investors.
