Dear Mr. Goldman:

We are pleased to propose that
Intasys Corporation (Intasys or the Company) retain Maxim Group
LLC (Maxim), on a non-exclusive basis, as its investment banker, strategic
advisor and financial advisor. The principal elements of the agreement
(Agreement) between Maxim and the Company are:

|1. |  | Services to be rendered:  The services that Maxim will render to the Company under
the terms of this Agreement will include the following:
|-- |  | ------------------------------------------------------------------------------------------------------------------------------------------

| | a) |  | Maxim
will provide the following strategic advisory services (Advisory
               Services):
| | -- |  | --------------------------------------------------------------------------------------------------

| |  | i) |  | advise
Intasys with respect to its strategic planning process and business plans
               including an analysis of markets, products, positioning, financial models,
               organization and staffing, potential strategic alliances, capital
requirements,                valuation and funding. To prepare for this advisory
function, Maxim will perform                a due diligence review of Intasys;
| |  | -- |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| |  | ii) |  | work
closely with Intasyss management team to develop a set of long and
               short-term goals with special focus on enhancing corporate and shareholder
               value. This will also include assisting Intasys in completing a gap
               analysis, i.e., helping Intasys determine key business developments
and                actions, including review of financing requirements and Intasyss
capital                structure, intended to help enhance shareholder value and Intasyss
               exposure to the investment community and;
| |  | --- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| |  | iii) |  | review
the Companys presentation and marketing materials and other
               materials used to present the Company to the investment community.
| |  | ---- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------

| | b) |  | Maxim
will help Intasys develop and evaluate financing or capital raising
               alternatives including public and private issues of equity or debt, as
               appropriate from time to time (Banking Services).
| | -- |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| |  | i) |  | Public
Offerings: In the event of a public offering, Maxim will have the right of
first refusal to act as lead or co-underwriter. Maxim will work with the
Company to manage the process of identifying, evaluating and selecting any
other underwriters. Maxim will prepare a comprehensive letter of intent
for the proposed transaction that will be provided to Intasys and will
supplement the terms of this Agreement. If Maxim is not selected as the
lead manager in a public offering, Intasys will use its best efforts to
ensure that Maxim receives at least 50% of the share allocation and 50% of
the total underwriting fees.
| |  | -- |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| |  | ii) |  | Private
Placements: Maxim will have the right of first refusal to act as placement
agent for any private placement. Maxim will prepare a comprehensive letter
of intent for the proposed transaction that will be provided to Intasys
and will supplement the terms of this Agreement.
| |  | --- |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | c) |  | Maxim
will provide Intasys with merger and acquisition services (the                M&A
Services). Maxim will assist the Company in determining                acquisition
or strategic partnering strategies and tactics from time to time, as
               appropriate. Maxim will advise and assist Intasys in identifying,
evaluating,                negotiating and structuring acquisitions, or strategic
investments or                partnerships which may be accomplished through a purchase
or sale of all or a                portion of the stock or assets, a merger or reverse
merger, joint venture,                licensing or marketing agreement or arrangement or
other business combination or                arrangement (Transaction) with
any entity (Candidate). A                strategic investment will include
any investment or exchange of cash, equity,                warrants, assets or debt as
part of a business relationship with a third party,                or any investment made
directly by a third party in the Company subject to a                term sheet or
agreement not marketed or syndicated beyond a specific investor.
| | -- |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | d) |  | If
requested by Intasys, Maxim will communicate its willingness to provide an
               opinion of fairness (a Fairness Opinion) of a particular
Transaction                to the Company, and if Maxim determines that it is able to
provide such a                Fairness Opinion, it will allow it to be used in connection
with materials filed                or submitted to the Securities and Exchange
Commission, or included in                information mailed to shareholders of Intasys
in connection with each                transaction.
| | -- |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

any Transaction completed by the Company with a Candidate Intasys shall pay
               Maxim a fee (Success Fee) upon closing equal to the sum of 2
               1⁄2% of the aggregate transaction value, provided that Maxim either
               introduces and/or performs specific services for the Transaction. The
minimum                Success Fee for any Transaction in this section shall be $200,000.
Any                Transactions currently being negotiated by the Company prior to the
signing of                this Agreement will not be subject to a Success Fee, with the
exception of Net                Creations, which was introduced by Maxim. The aggregate
transaction value shall                include the sum of cash and the fair market value
at the time of the closing of                a Transaction of equity securities;
warrants; contingent payments; deferred                payments; non-compete agreements;
liabilities assumed, acquired, retired or                defeased (other than normal

in such a Transaction; the fair market value of any                licensing, marketing

| | e) |  | The
Company will reimburse Maxim in a timely manner for any reasonable
               out-of-pocket expenses relating to activities under this Agreement. Any
legal or                other expenses must be pre-approved by the Company.
| | -- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | f) |  | In
no case will any fee obligations of the Company to any other financial
               advisor or any other person in connection with this transaction reduce the
fees                owed by the Company to Maxim under this Agreement.
| | -- |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | g) |  | Maxim
and the Company agree to establish an escrow agreement as soon as
               practicable to govern the flow of all Transaction related fees.
| | -- |  | ------------------------------------------------------------------------------------------------------------------------------------------------------

|3. |  | Term of Agreement.  The term of this agreement is indefinite.  However the
Company or Maxim may terminate it upon 30 days written notice. If such a
notice is sent by the Company, the monetary consideration will be payable
by the Company for the ensuing five months; however, the warrant
consideration will cease after the 30 days written notice. If Maxim sends
such a notice, both the monetary and warrant consideration will cease
immediately.  Any future obligation that could be reasonably expected
to survive this Agreement will survive termination of this Agreement.  Specific
surviving conditions will include, but not be limited to:  (i)
payment of Success Fees earned under section 2(d) during the Term and for
Transactions considered during the Term and completed within 18 months of
the termination of this Agreement, and (ii) Section 4, Indemnity.

|4. |  | Indemnity.
The Company agrees to indemnify and hold harmless Maxim, including any
affiliated companies, and their respective officers, directors, controlling
persons and employees and any persons retained in connection with a
proposed financing (whether or not consummated) (the Indemnitees),
from and against all claims, damages, losses, liabilities and expenses as
the same are incurred (including any legal or other expenses incurred in
connection with investigating or defending against any such loss, claim,
damage or liability or any action in respect thereof), related to or
arising out of its activities hereunder. Notwithstanding the foregoing,
the Company shall not be liable for indemnity under this Agreement in
respect of any loss, claim, damage, liability or expense arising from Maxims
misconduct in performing the services described above. This provision
shall survive any termination of Maxims engagement as well as the
consummation or abandonment of any Transaction, placement or offering.
Intasys agrees that any and all decisions, actions and results with
regards to Intasyss operating, financial and other business plans
are the sole responsibility of Intasyss management, and that Maxims
engagement will in no way expose Maxim to any liability, including but not
limited to, liability for any financing, operating, financial, merger,
acquisition, managerial, or other results achieved by the Company, as well
as the implementation of, or the results achieved by, strategies or
business plans on which Maxim has provided review or advice.

|5. |  | Disclaimers.
|-- |  | ------------

| | a) |  | It
is understood by Maxim and the Company that the Companys ability to
               raise capital will be affected by various factors at the time of a
proposed                offering, including but not limited to, stock market conditions,
competitive                positioning of Intasyss products, achieving business
plan goals that have                been mutually agreed upon by Maxim and the Company,
short- and long-term                business prospects, the plans and performance of the
management team and the                capital structure of the Company. In the event
that Maxim does not deem itself                able to act as a manager for a proposed
placement or offering, subject to                Maxims sole reasonable discretion,
it will advise the Company on an                appropriate course of action.
| | -- |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | b) |  | In
performing its M&A Services hereunder, Maxim may rely entirely on
               publicly available information and such other information as may be
furnished to                Maxim by the Company or a Candidate, and has not and does not
assume any                responsibility for independent verification of such information
or independent                appraisal or valuation of assets.
| | -- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|6. |  | Entire Agreement and Governing Law. This Agreement may not be amended or modified
except in writing, and shall be governed by and construed in accordance
with the laws of the State of New York.
