      Re: BDR / Cytomedix Consulting Arrangement

Dear Jim:

      This letter (the "Agreement") sets forth the terms of the engagement of
BDR Consulting, Inc. (the "Consultant") to provide such management, financing,
marketing and strategic consulting services to Cytomedix, Inc. (the "Company")
and its affiliates as we shall mutually agree ("Consulting Services").

      1. Term. The Consultant shall provide Consulting Services during the
period commencing on the date that the Company's Plan of Reorganization becomes
effective (the "Effective Date"), and continuing until June 30, 2005 (the
"Term"), unless sooner terminated pursuant to the provisions of Section 11
hereof.

      2. Services Rendered. During the Term, the Consultant shall be immediately
and fully accessible to the Company at all times during normal business hours
and provide Consulting Services continually as reasonably requested by the
Company. In the event that the Company desires to engage the Consultant to
perform services other than the Consulting Services (e.g., additional capital
fundraising), then the parties shall negotiate the terms and conditions of any
such special engagement. The Consultant shall have the right to perform
consulting services to parties other than the Company; provided, however, that
the Company shall be granted first priority with respect to the Consultant's
time and such other services provided by the Consultant shall not compete with
the Company's business.

      3. Oversight. The Consultant shall provide Consulting Services to the
Company and shall work directly with the Company's management; provided,
however, that the Consultant shall be supervised by and shall report directly to
the Company's Board of Directors.

      4. Compensation. As compensation for providing the Consulting Services to
the Company, the Consultant will receive compensation of One Hundred Eight
Thousand US Dollars ($108,000) per annum. Such compensation will be paid to the
Consultant monthly, on the first day of each month, commencing on the Effective
Date, in twelve (12) equal installments of Nine Thousand US Dollars ($9,000). In
the event that the Effective Date falls on a date that is not the first day of a
month, then the initial compensation payment shall be pro-rated accordingly and
shall be paid on the Effective Date.

      5. Initial Compensation Payment. In addition to any pro-rated monthly
payment made in accordance with Section 4 above, the Company shall pay to the
Consultant, on the Effective Date, an amount equal to $27,000, which shall
represent payment in advance for the months of April, May and June, 2005 (the
"Initial Payment"). The Initial Payment shall be non-forfeitable except as
provided in Section 11(d) below.

      6. Expenses. Upon presentation of acceptable documentation, the Company
will promptly reimburse the Consultant for all reasonable out-of-pocket expenses
you incur in connection with providing Consulting Services.

      7. Company Stock Options.

         (a) Option Grant. The Company shall grant the Consultant stock options
for three hundred thousand (300,000) shares of the Company's stock in accordance
with the Company's 2002 Stock Option Plan. Options for one hundred thousand
(100,000) shares shall be fully vested on the Effective Date, options for an
additional one hundred thousand (100,000) shares shall be fully vested on the
first anniversary of the Effective Date, and options for the remaining one
hundred thousand (100,000) shares shall be fully vested on the second
anniversary of Effective Date. The exercise price shall be the fair market value
on the Effective Date. In the event that the Company terminates this Agreement
pursuant to Section 11(a) below, and in addition to any Consultant options
vested as of such termination, options for an additional fifty thousand (50,000)
shares of the Company shall immediately vest; provided, however, that the number
of shares for which the Consultant shall have options shall not exceed 300,000.
The Company and Consultant agree that Consultant may make the "Section 83(b)"
election for federal and state income taxes with respect to the options granted
under this Section 7(a).

         (b) Option Terms. The options to purchase shares shall expire ten (10)
years from the date each option becomes exercisable. Immediately preceding a
Change of Control, as defined in the 2002 Stock Option Plan, all issued and
unvested stock options shall immediately become fully vested and exercisable by
Consultant.

      8. Status. The Consultant is an independent contractor, and not an agent,
of the Company or any of its affiliates for any purpose whatsoever. The
Consultant will have no authority to, and agree not to, assume or create any
obligation or liability, express or implied, on behalf of the Company or any of
its affiliates, or bind the Company or any of its affiliates in any manner or to
anything whatsoever. Except as otherwise provided herein, the Consultant agrees
to be liable for and to pay its own expenses.

      9. Representation. The Consultant hereby represents and warrants to the
Company that its execution, delivery and performance of this Agreement, and the
consummation of the transactions contemplated hereby, does not and will not
conflict with, contravene or result in a violation or breach of or default under
(with or without the giving of notice or the lapse of time or both), any
contract,

agreement or understanding to which the Consultant is a party or by which the
Consultant is or may be bound, including without limitation, any non-competition
or similar agreement.

      10. Confidential Information. The Consultant agrees that all matters
concerning the Company, any affiliate of the Company, or any business partner of
the Company will be treated by the Consultant as Confidential Information and

the Company may terminate this Agreement for any reason.

         (b) In the event that the Consultant either (i) fails to perform, in a
timely fashion, the Consulting Services, after written notice of the alleged
failure and a fifteen (15) day opportunity to cure has been given, or (ii)
breaches this Agreement, the Company may immediately terminate this Agreement.

         (c) The Consultant may terminate this Agreement due to a material
breach hereof by the Company after written notice of the alleged breach and a

         (d) Solely in the event that the Company terminates this Agreement in
accordance with Section 11(b) above, the Initial Payment described in Section 5
shall be forfeited and the Consultant shall repay such Initial Payment to
Company within ten (10) days of the effective date of such termination. In all
other events of termination, the Company shall pay the Consultant for the fees
and expense reimbursement due and payable through the effective date of the
termination (without offset or deduction against the Initial Payment) and
Consultant shall be entitled to retain the Initial Payment as a termination
payment.

you and the Company concerning the subject matter hereof. No amendment,
modification or discharge of this Agreement, and no waiver hereunder, shall be
valid or binding unless set forth in writing and signed by you and the Company.
