             NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS


Note 1.  Basis of Presentation

   The condensed consolidated financial statements are unaudited and reflect all
   adjustments  (consisting only of normal recurring  adjustments) which are, in
   the opinion of management, necessary for a fair presentation of the financial
   position  and  operating  results  for the  interim  periods.  The  condensed
   consolidated  financial  statements  should be read in  conjunction  with the
   consolidated  financial  statements  for the year ended December 31, 1999 and
   notes  thereto  contained in the  Company's  Annual Report on Form 10-K filed
   with the  Securities and Exchange  Commission.  The results of operations for
   the three months ended September 30, 2000 are not  necessarily  indicative of
   the results to be expected  for the entire  fiscal year ending  December  31,
   2000.


Note 2.  Net Income per Common Share

   Net income per common share, basic, is computed by dividing the net income by
   the weighted  average  number of common  shares  outstanding.  Net income per
   common  share,  diluted,  is computed by dividing  net income by the weighted
   average number of shares  outstanding plus dilutive common share equivalents.
   The following table sets forth the computation of basic and diluted  earnings
   per share:

Item 2.  Management's  Discussion  and  Analysis of  Financial  Condition  and
Results of Operations

Results of Operations

Revenues.  The  Company's  revenues  for the third  quarter of fiscal  year 2000
decreased  27 percent  to  $18,919,000  compared  to  $25,979,000  for the third
quarter of the prior fiscal year. The revenue  decrease is  attributable  to the
termination  of  35   hospital-based   programs   during  the  last  12  months,
renegotiation  of  contract  terms at  approximately  67  programs,  and reduced
Procuren sales.  The reduction in revenue was partially offset by the opening of
10 new programs over the last 12 months.  The Company ended the third quarter of
2000 with 133 hospital based Wound Care Centers operating compared to 160 at the
end of the third quarter 1999.  Revenues at existing centers declined 20 percent
in the third  quarter of 2000 as compared to the same period in 1999,  primarily
due to such contract renegotiations and declining Procuren revenues. The Company
anticipates  that as a result of the August  2000  implementation  by the Health
Care  Financing  Administration  (HCFA) of the  Outpatient  Prospective  Payment
System  (OPPS) for  hospitals  and new provider  based  designation  guidelines,
reimbursement  rates to  hospitals  will be  insufficient  resulting  in reduced
revenues to the hospitals.  The Company  expects that it will need to modify its
management  contracts with many of its hospital  customers  which will result in
reduced revenue to the Company or even contract  terminations.  As hospitals are
currently facing financial challenges  associated with lower occupancy rates and
reduced revenue  streams due to pricing  pressures from Medicare and third party
payors, there can be no assurances that the Company's renegotiation efforts will
be successful. The termination or non-renewal of a material number of management
contracts could result in a continued decline in the Company's  revenue.  As the
result of the recent legal action  against the  Company,  further  unanticipated
terminations  or  non-renewals  may  take  place.  Additionally,   new  business
development has been slow given the legal  uncertainties  facing the Company and
the pending  OPPS  implementation.  Any  inability of the Company to develop new
Wound Care Centers could  further  reduce  revenue.  The Company has a number of
initiatives  to  counter  the  decline  in  revenue,  although  there  can be no
assurance that the initiatives will be successful.  Total new patients decreased
6 percent from 16,225 in the third quarter of 1999 to 15,201 for the same period
in  2000.  The  total  number  of new  patients  receiving  Procuren(R)  therapy
decreased from 1,359 in the third quarter of 1999 to 831 in the third quarter of
2000. The percentage of patients receiving  Procuren(R) therapy decreased during
the third  quarter of 2000 to 5 percent  from 8 percent  for the same  period in
1999. For the first nine months of 2000 revenues totaled $62,709,000 compared to
$76,842,000  for the same  period in 1999,  an 18%  decrease.  The  decrease  in
revenues  is  attributable  to  contract  terminations,   renegotiations  and  a
reduction  in  Procuren  revenues  as the  result  of a  reduction  in  Procuren
patients.  Total new  patients  for the first  nine  months of 2000 were  46,794
compared to 46,706 for the same  period in 1999,  a 0.2  percent  increase.  The
total number of new patients  receiving Procuren therapy decreased 40 percent to
2,787 in the first nine  months of 2000 from  4,665 in the first nine  months of
1999. The Company  believes that this decrease is attributable to an increase in
the  percentage  of less severe  chronic  wounds being  treated at the Company's
Wound  Care  Centers(R),  for which  physicians  are less  likely  to  prescribe
Procuren(R),  a lack of  available  reimbursement  for  Medicare  patients,  the
inability of hospitals to assume  collection risks due to financial  constraints
and  increased  competition  from other  wound  healing  products.  The  Company
anticipates that the percentage of patients receiving  Procuren(R) will continue
to decline in the future.

Costs of Product Sales and Services. Costs of product sales and services for the
third quarter  decreased  from  $15,717,000  in 1999 to  $12,085,000  in 2000, a
decrease of 23 percent and for the first nine months of 2000 totaled $39,573,000
compared to $45,280,000  for the same period in 1999. For the third quarter 2000
the  decrease is  attributable  to reduced  staffing and  operating  expenses of
approximately  $1,730,000 related to the operation of 133 programs at the end of
the third quarter 2000  compared  with 160 programs  operating at the end of the
third quarter 1999, as well as reduced  expenditures of  approximately  $367,000
related   to   Procuren   production.   Additionally,   there   were  11   fewer
under-arrangement  programs in operation at the end of the third quarter of 2000
as compared  with the same  period in 1999 at which the  services  component  of
costs is  higher  than at the  Company's  other  centers  due to the  additional
clinical staffing and expenses that these models require.  For the third quarter
of 2000 this  accounted  for a  reduction  of  approximately  $772,000.  Cost of
product   sales  and  services  for  the  quarter  also   includes   charges  of
approximately  $388,000 related to the elimination of 40 sales positions and the
elimination of field positions associated with Wound Care Center closings.  As a
percentage  of  revenues,  costs of  product  sales and  services  for the third
quarter of 2000 was 64 percent  compared  to 60 percent  for the same  period in
1999.  For the first  nine  months of 2000 cost of  product  sales and  services
decreased 12 percent. The decrease is primarily attributable to reduced staffing
and operating  expenses of approximately  $2,928,000 related to the operation of
133 programs at the end of the third  quarter of 2000  compared with 160 for the
same period in 1999 and reduced expenses of approximately  $1,015,000 related to
Procuren  production.   Additionally,  there  were  11  fewer  under-arrangement
programs in operation at the end of the third  quarter of 2000 as compared  with
the same period in 1999 at which the services  component of costs is higher than
at the  Company's  other  centers due to the  additional  clinical  staffing and
expenses  that these  models  require.  For the first  nine  months of 2000 this
accounted for a reduction of approximately  $773,000.  For the first nine months
of  2000  cost  of  product  sales  and  services   also  includes   charges  of
approximately  $388,000  related  to  the  elimination  of  40  sales  positions
associated with Wound Care Center closings. As a percentage of revenues, cost of
product,  sales and  services  were 63 percent for the first nine months of 2000
compared  to 59 percent  for the same  period in 1999.  The  increase in cost of
sales  as a  percentage  of  revenues  for  2000  is  attributable  to  contract
renegotiations  and the  resulting  decrease in revenues as well as a decline in
the Procuren margin due to declining Procuren sales.

Selling,  General  and  Administrative.   Selling,  general  and  administrative
expenses for the third quarter  decreased from  $7,150,000 in 1999 to $7,017,000
in 2000 a decrease of 2 percent, and for the first nine months of 2000 increased
5 percent to $20,683,000  compared to  $19,652,000  for the same period in 1999.
Selling,  general  and  administrative  costs for the  quarter  include  charges
related to the closing of the  Company's  Dallas field  office of  approximately
$627,000.  The  increase  for the nine months is  primarily  attributable  to an
increase in legal and other costs related to the  Department of Justice  actions
and  shareholder  class  action suit of  approximately  $635,000,  approximately
$308,000 of consulting  and related  costs  associated  with  preparing for OPPS
implementation,  and $627,000 of costs  related to the closing of the  Company's
Dallas  field  office.  As  a  percentage  of  revenues,  selling,  general  and
administrative expenses were 37 percent in the third quarter of 2000 compared to
28  percent  for 1999 and for the nine  months  were 33 percent  compared  to 26
percent  for the same  period in 1999.  The  increase  for the  quarter and nine
months is  attributable  to the higher legal and  consulting  expense,  costs of
closing the Company's Dallas field office and decreased revenue in 2000.

                                       8

Net Income.  Net income was  $309,000  or $0.04 per  diluted  share in the third
quarter of 2000  compared to  $2,201,000 or $0.22 per diluted share in the third
quarter of 1999 and for the first nine months of 2000 was $.27 per diluted share
compared to $.77 per diluted share for the same period in 1999.  The decrease in
earnings for the third quarter and first nine months of 2000 is  attributable to
a reduced  revenue  base  which  impacted  wound  care  center  margins  and the
additional legal and consulting expenses, as well as the charges for closing the
Company's  Dallas  field  office  and the  elimination  of sales  positions  and
positions associated with Wound Care Center closings.

Liquidity and Capital Resources.

Working  capital  was $47.1  million at  September  30,  2000  compared to $55.5
million at December  31,  1999.  Total cash,  cash  equivalents  and  marketable
securities  held-to-maturity  as of September 30, 2000 was $46.1 million and was
invested  primarily in highly  liquid money market funds,  commercial  paper and
government  securities.  The ratio of current assets to current  liabilities was
4.4:1 at December 31, 1999 and 3.8:1 at September 30, 2000.

Cash flows  provided by  operations  for the first nine  months of 2000  totaled
$13,617,000  primarily  attributable  to the net  income  for the  period  and a
reduction in accounts  receivable  days  outstanding  to 64 days from 76 days at
December  31,  1999.  Cash  flows  provided  by  investing   activities  totaled
$2,471,000 primarily attributable to maturities of marketable  securities.  Cash
flows used in financing activities totaled $12,619,000 primarily attributable to
the Company's repurchase of 2,075,000 shares of its common stock.

For the first nine months of 2000,  the Company  experienced  a net  decrease in
accounts  receivable of $7,236,000  and a decrease in the average number of days
receivables outstanding to 64 days as of September 30, 2000 compared to 76 as of
December 31, 1999.

The Company's  longer-term  cash  requirements  include  working capital for the
expansion of its wound care business.  Other cash  requirements  are anticipated
for capital  expenditures  in the normal course of business,  the acquisition of
software,   computers  and  equipment   related  to  the  Company's   management
information  systems,  and the  repurchase of Company  stock.  Additionally  the
Company  expects to incur  significant  legal costs related to the Department of
Justice actions and shareholder  class action lawsuits filed against the Company
(See Legal  Proceedings,  Part II Item 1). The Company expects that based on its
current  business  plan,  its existing  cash,  cash  equivalents  and marketable
securities will be sufficient to satisfy its current working capital needs.  The
effects of  inflation  and foreign  currency  translation  risks are  considered
immaterial.

Item 3.     Quantitative and Qualitative Disclosures About Market Risk

The  Company  does not have  operations  subject  to risks of  material  foreign
currency  fluctuations,  nor does it use derivative financial instruments in its
operations or  investment  portfolios.  The Company  places its  investments  in
instruments  that  meet high  credit  quality  standards,  as  specified  in the
Company's investment policy guidelines. The Company does not expect any material
loss with  respect to its  investment  portfolio  or  exposure  to market  risks
associated with interest rates.

                              TRANSITION AGREEMENT


         THIS  TRANSITION  AGREEMENT  effective  as  of  August  18,  2000  (the
"Agreement") is made by and between CURATIVE HEALTH SERVICES,  INC., a Minnesota
corporation (the  "Company"),  and CAROL GLEBER,  an individual  residing in the
State of Texas (the "Executive").

         WHEREAS,  pursuant  to an Amended  and  Restated  Employment  Agreement
effective as of September 1, 1997 between the Company and  Executive,  a copy of
which is annexed hereto as Exhibit A (the "Employment Agreement"), Executive has
been serving as the Company's Senior Vice President and Chief Operating Officer;

         WHEREAS,  the parties have agreed that Executive will resign  effective
as of the close of business on September 1, 2000 from her current position as an
executive  officer of the Company (the effective date of such  resignation,  the
"Transition Date"); and

         WHEREAS,  in light of  Executive's  history  with the  Company  and her
extensive  knowledge of the Company's  business,  the Company  desires to reward
Executive  for her past  contributions  to the success of the Company and assure
her  reasonable   availability   and  cooperation  in  connection  with  certain
litigation and regulatory matters on the terms and subject to the conditions set

valuable  consideration,  the  receipt  and  sufficiency  of  which  are  hereby
acknowledged, the parties hereto agree as follows:

1.  Resignation.  Effective as of the Transition Date,  Executive shall and does
hereby resign as an executive  officer of the Company.  Accordingly,  subject to

release and the Executive  Claims shall not include:  (i) all claims which arise
from the Company's obligations under this Agreement;  (ii) all claims in respect
of  Executive's  rights  under the  Company's  401(k)  Plan;  (ii) all claims in
respect of Executive's COBRA rights after the Transition Date or (iv) all claims
in respect of Executive's  rights to  indemnification as an employee and officer
of the  Company  pursuant  to  applicable  law or the  Company's  organizational
documents.

                  Executive  agrees  that  she  will not  hereafter  pursue  any
Executive Claim released herein against any Company Releasee by filing a lawsuit
in any local,  state or  federal  court,  and she shall not seek  damages of any
nature,  attorney's  fees, or costs from the Company or any of the other Company
Releasees in connection therewith.

                  (b) As a material  inducement  to Executive to enter into this
Agreement and in consideration for Executive's  agreements contained herein, the
Company hereby  irrevocably and  unconditionally  releases,  acquits and forever
discharges Executive, and each of her heirs, predecessors,  successors, assigns,
agents, representatives and attorneys, and all persons acting by, through, under
or in concert with any of them  (collectively,  the "Executive  Releasees") from
any and all charges,  complaints,  claims, liabilities,  obligations,  promises,
agreements,  controversies,  damages,  actions, causes of action, suits, rights,
demands,  costs, losses, debts and expenses (including attorneys' fees and costs
actually  incurred),  of any  nature  whatsoever,  known or  unknown,  which the
Company now has,  owns or holds,  or claims to have,  own or hold,  or which the
Company at any time  heretofore  had,  owned or held, or claimed to have, own or
held against each or any of the Executive  Releasees relating to or arising from
Executive's employment by the Company ("Company Claim" or "Company Claims"). The
Company Claims shall include, without implication of limitation, any claims made
or which could have been made based upon the  Employment  Agreement;  all claims
for breach of express or implied contract;  all claims for breach of any express
or implied covenant of employment, including the covenant of good faith and fair
dealing; all claims for interference with contractual or advantageous relations,
whether prospective or existing; all claims for deceit or misrepresentation; all
claims relating to the Executive's  employment with the Company,  and all claims
for attorneys' fees and costs. The foregoing  notwithstanding,  this release and
the Company  Claims  shall not include all claims  which arise from  Executive's
obligations under this Agreement.

                  The  Company  agrees  that it will not  hereafter  pursue  any
Company Claim  against any Executive  Releasee by filing a lawsuit in any local,
state or federal court, and it shall not seek damages of any nature,  attorney's
fees,  or costs  from  Executive  or any of the  other  Executive  Releasees  in
connection therewith.

7. Transition; Litigation and Regulatory Cooperation.  Executive agrees to exert
her best efforts through  September 15, 2000 in assisting the Company in closing
its office in Dallas,  Texas.  Executive further agrees that until September 15,
2000 she will  provide  such other  assistance  as the  Company  may  reasonably
request  in  connection   with  the   transition  of   Executive's   duties  and
responsibilities  to such other Company personnel as the Chief Executive Officer
of the  Company  may  reasonably  request.  In  addition,  from  and  after  the
Transition Date,  Executive agrees to reasonably  cooperate with the Company, at
the  Company's  sole cost and  expense,  in the  defense or  prosecution  of any
claims,  actions or investigations  which already have been brought or which may
be brought in the future  against or on behalf of the  Company  which  relate to
events or occurrences  that transpired  during  Executive's  employment with the
Company.  Executive's  reasonable  cooperation in connection with such claims or
actions shall include,  without  implication of limitation,  being  available to
meet with counsel or prepare for discovery or trial and to testify truthfully as
a  witness  when  reasonably  requested  by  the  Company  at  reasonable  times
designated by the Company.  The Company shall promptly  reimburse  Executive for
her expenses,  including  but not limited to all directly  related long distance
calls, travel,  lodging, food, reasonable cost of legal representation,  and any
other  expenses  which are  reasonably  required  for  Executive  to  reasonable
cooperate with the obligations of this paragraph.  Provided,  however, that with
respect to travel,  lodging and food, if Executive provides reasonable notice to
the  Company of the  amount and  sources  of the  expenses,  at the  Executive's
request the Company will either pay the expenses directly or advance the cost of
those expenses to Executive.  Executive  further agrees that unless  required by
law or legal  process she will not  voluntarily  disclose to any person or party
any  information  that is adverse to the Company,  maintain the  confidences and
privileges of the Company, and testify truthfully regarding any information that
she is  obligated  to  disclose.  Nothing  herein  shall be  deemed  to  prevent
Executive from complying to the full extent required by law, including,  but not
limited to, any court order or other  legal  process  that may be issued to her.
Provided,  however,  that nothing contained in this paragraph shall unreasonably
interfere with Executive seeking and maintaining future employment.  The Company
and its  legal  representatives  will  use  their  best  efforts  to  coordinate
reasonable requests under this paragraph,  which will not jeopardize Executive's
future or on-going employment.

8.  Nondisparagement.

                  (a) Executive will not,  directly or  indirectly,  for her own
account  or for or on behalf  of any  other  person  or  entity,  whether  as an
officer, director,  employee,  partner,  principal, joint venturer,  consultant,
investor,  shareholder,  independent contractor or otherwise speak or act in any
manner  that is intended  to be or is  derogatory  of the Company or the Company
Releasees,  unless  required  by law or  legal  process  to  truthfully  provide
information  which would  otherwise  violate  this  section.  Specifically,  and
without  implication of limitation,  Executive  agrees not to take any action or
make any statement, written or oral, which disparages or criticizes the Company,
its  management,  or its business  practices,  or which  disrupts or impairs the
Company's  normal  operations,  unless  required  by law  or  legal  process  to
truthfully provide information which would otherwise violate this section.

                  (b) The Company  agrees that the Company and its  officers and
directors  will not,  directly or  indirectly,  for its own account or for or on
behalf of any other  person or entity,  whether  as  partner,  principal,  joint
venturer,  investor,  shareholder,  independent contractor or otherwise speak or
act  in any  manner  that  is  intended  to be or is  derogatory  of  Executive.
Specifically, and without implication of limitation, the Company agrees that the
Company and the  Company's  officers and  directors  will not take any action or
make any statement, written or oral, which will directly or indirectly disparage
or criticize Executive.

9. Right to Consider Agreement.  Executive  acknowledges that she has been given
the  opportunity,  if she so desired,  to consider this Agreement for twenty-one
(21) days before executing it. If not signed by Executive and returned to Robert
J. Dwyer, Esq.,  counsel to the Company,  so that it is received by the close of
business  on the  twenty-second  (22nd)  day after  Executive's  receipt  of the
Agreement,  this Agreement will not be valid. In addition, if Executive breaches
any of the conditions of the Agreement  within the  twenty-one  (21) day period,
the offer of this Agreement will be withdrawn and her execution of the Agreement
will not be valid.  In the event that  Executive  has  executed  this  Agreement
within  less  than  twenty-one  (21)  days of the date of its  delivery  to her,
Executive  acknowledges  that such decision was entirely  voluntary and that she
had the  opportunity to consider this Agreement for the entire  twenty-one  (21)
day period.  The Company  acknowledges  that for a period of seven (7) days from
the date of the execution of this Agreement, Executive shall retain the right to
revoke  this  Agreement  by written  notice that is received by Robert J. Dwyer,
Esq.  before the end of such period,  and that this  Agreement  shall not become
effective or enforceable until the expiration of such revocation period.

10. Advice of Counsel.  Executive  represents and agrees that the Company hereby
advises her to discuss all aspects of this  Agreement  with her attorney  before
signing the Agreement;  that she has carefully read and fully understands all of
the provisions of this Agreement and that she is voluntarily  entering into this
Agreement.

11.  Confidentiality.  Each of  Executive  and the Company and their  respective
counsel  agree to hold the  terms and  conditions  of this  Agreement  in strict
confidence,  except as may be required by law. If either  party or such  party's
counsel is required by law to reveal  information  required by this paragraph to
be kept  confidential,  such  party  will  notify  the other  party  before  the
information  is  revealed of the  information  that she or it will  reveal,  the
reason therefore, and the identity of the entity seeking the information.

12. No Admission of Fault.  Executive  agrees that the Company's  willingness to
enter into this  Agreement  does not  constitute and should not be construed as,
any  admission of liability or fault on the part of the Company or its officers,
directors, employees and agents.

13.  Written   Statement;   Letter  of   Recommendation.   Notwithstanding   the
confidentiality  provisions  contained  herein,  the parties  agree that (i) the
statement  that is annexed as Exhibit C may be  distributed  by Executive or the
Company to anyone  following the Transition  Date, and (ii) the Chief  Executive
Officer of the Company  shall  furnish to  Executive a letter of  recommendation
that is mutually acceptable to the Chief Executive Officer and Executive.

14.  Entire  Agreement.  This  Agreement  supersedes  any and all other prior or
contemporaneous  agreements,  either  oral or in  writing,  between  the parties
hereto with respect to the subject matter hereof, including, without limitation,
the Employment  Agreement,  and this Agreement contains all of the covenants and
agreements  between the parties with respect to the  termination  of Executive's
employment  and the severance and other benefits she shall receive in connection
therewith; provided, however, that all Options which will vest pursuant to their
terms after the Benefit Period shall lapse and be forfeited as of the Transition
Date and the  unvested  portion of the  Restricted  Stock  Grant as set forth on
Exhibit B shall be forfeited.

15. Law  Governing  This  Agreement.  This  Agreement  shall be  governed by and
construed in accordance  with the laws of the State of New York,  without regard
to conflicts of laws principles.

16.  Waivers.  No waiver at any time of any term or provision of this  Agreement
shall be construed as a waiver of any other term or provision of this  Agreement
and that a waiver at any time of any term or provision of this  Agreement  shall
not be  construed  as a  waiver  at any  subsequent  time  of the  same  term or
provision.

17.  Amendment.  No amendment or  modification of this Agreement shall be deemed
effective unless and until executed in writing by each party hereto.

18.  Severability and Limitation.  All agreements and covenants contained herein
are  severable  and in the event any of them  shall be held to be invalid by any
competent  court,  this  Agreement  shall  be  interpreted  as if  such  invalid
agreements  or covenants  were not contained  herein.  Should any court or other
legally constituted  authority determine that for any such agreement or covenant
to be  effective  that it must be modified to limit its  duration or scope,  the
parties  hereto  shall  consider  such  agreement  or  covenant to be amended or
modified  with respect to duration  and/or scope so as to comply with the orders
of any such court or other legally  constituted  authority,  and as to all other
portions of such  agreement  or  covenants  they shall  remain in full force and
effect as originally written.

19.  Headings.  All  headings  set  forth in this  Agreement  are  intended  for
convenience  only and shall not control or affect the meaning,  construction  or
effect of this Agreement or of any of the provisions hereof.

20. Assignment. The Company shall have the right to assign this Agreement and to
delegate all of its rights, duties and obligations hereunder to any entity which
controls the Company,  which the Company  controls or which may be the result of
the merger,  consolidation,  acquisition  or  reorganization  of the Company and
another entity.  Executive agrees that this Agreement is personal to her and her
rights and interests hereunder may not be assigned,  nor may her obligations and
duties hereunder be delegated,  and that any attempted  assignment or delegation
in violation  of this  provision  shall be void.  Provided,  however,  that upon
Executive's  death her rights under this  Agreement will inure to the benefit of
her estate, successors and assigns.

21.  Counterparts.  This  Agreement may be executed via  facsimile  transmission
signature and counterparts,  each of which shall be deemed to be an original but
all of which together will constitute one and the same instrument.

Section 2.8       Adjustment Amount.

(a) The "Adjustment Amount" (which may be a positive or negative number) will be
an amount equal to the  amount  determined by subtracting the
Interim Tangible Assets Book Value (as defined in Section 2.8(b) below) from the
Closing  Tangible  Assets  Book Value (as  defined in  Section  2.8(c)).  If the
Adjustment Amount is positive,  the difference shall be paid by wire transfer by
Cytomedix,  Inc. to an account  specified by Seller. If the Adjustment Amount is
negative, such difference shall be paid by wire transfer by Seller to an account
specified  by  Cytomedix,  Inc.  All  payments  due and owing under this Section
2.8(a) shall be made together with interest at the rate of ten percent (10%) per
annum,  which  interest  shall begin accruing on the Closing Date and end on the
date the payment is made.  Within three (3) Business Days after the  calculation
of the Adjustment  Amount becomes binding and conclusive on the parties pursuant
to Sections  2.8(d) and 2.8(e),  Seller or Cytomedix,  Inc., as the case may be,
shall make the wire transfer payment provided for in this Section 2.8(a).

(b)  "Tangible  Assets Book Value" shall mean the tangible  assets book value of
the Tangible  Personal  Property and the  Inventories  as of any given date. The
Tangible  Assets Book Value of Seller as of  September  30,  2000 (the  "Interim
Tangible Assets Book Value") was $3,102,450,  as more  specifically set forth on
Schedule 2.8(b) attached  hereto.

(c) Cytomedix, Inc. shall determine the book value (the "Closing Tangible Assets
Book Value") of the Tangible  Personal  Property and the  Inventories  as of the
Closing Date (the "Closing Date Valuation") using generally accepted  accounting
principles  as applied in the  determination  of the book value of the  Tangible
Personal  Property and  Inventories as set forth in Schedule  2.8(b);  provided,
however,  that the Assets listed on Schedule  2.8(b) shall be deemed to have the
same book value in the Closing Date  Valuation  as set forth on Schedule  2.8(b)
and any adjustment  based upon the Closing Date Valuation  shall result from any
difference in the Assets included in the Closing Date Valuation  compared to the
Assets  included on Schedule  2.8(b) other than changes  reflecting  the further
depreciation  of the Assets using GAAP  consistently  applied.  Cytomedix,  Inc.
shall deliver the Closing Date  Valuation and its  determination  of the Closing
Tangible  Assets Book Value to Seller within  forty-five (45) days following the
Closing Date.

(d)  If  within  fifteen  (15)  days  following  delivery  of the  Closing  Date
Valuation,  Seller has not given Cytomedix, Inc. written notice of its objection
to the Closing Tangible Assets Book Value  calculation  (which notice must state
the basis of Seller's  objection),  then the Closing  Tangible Assets Book Value
shall be binding and  conclusive  on the parties and shall be used in  computing
the Adjustment Amount.

(e) If Seller duly gives Cytomedix, Inc. such notice of objection, and if Seller
and Cytomedix,  Inc. fail to resolve the issues  outstanding with respect to the
Closing Date Valuation and the  calculation of the Closing  Tangible Assets Book
Value  within  fifteen  (15)  days of  Cytomedix,  Inc.'s  receipt  of  Seller's
objection notice,  Seller and Cytomedix,  Inc. shall submit the issues remaining
in dispute to a certified public  accountant  mutually agreed to by KPMG LLP and
Ernst & Young LLP (the  "Independent  Accountants").  If issues are submitted to
the Independent Accountants for resolution, (i) Seller and Cytomedix, Inc. shall
furnish or cause to be furnished to the Independent Accountants such work papers
and other  documents  and  information  relating to the  disputed  issues as the
Independent  Accountants  may  request  and are  available  to that party or its
agents and shall be  afforded  the  opportunity  to  present to the  Independent
Accountants  any  material  relating to the  disputed  issues and to discuss the
issues  with  the  Independent  Accountants;   (ii)  the  determination  by  the
Independent Accountants, as set forth in a notice to be delivered to both Seller
and Cytomedix, Inc. within thirty (30) days of the submission to the Independent
Accountants  of the issues  remaining  in dispute,  shall be final,  binding and
conclusive on the parties;  and (iii) Seller and Cytomedix,  Inc. will each bear
fifty percent  (50%) of the fees and costs of the  Independent  Accountants  for
such determination.

     (iv) cause Buyer to become subject to, or to become liable for, the payment
          of any Tax;

          any Seller Contract; or

     (vi) result in the imposition or creation of any  Encumbrance  upon or with

in each case of (i)  through  (vi) above,  the result of which could  reasonably
expected to have a material  adverse  effect on the  financial  condition of the

Facilities individually.

     (c) Except as set forth in Schedule 3.2(c),  Seller is not required to give

operations  or financial  condition of the  Procuren  Operations  or the Assets,

Legal  Requirements  regarding  employment and employment  practices,  terms and
conditions of employment,  wages and hours, and  Occupational  Safety and Health
Laws,  including laws concerning  unfair labor  practices  within the meaning of
Section  8  of  the  National   Labor   Relations  Act  and  the  employment  of
non-residents under the Immigration Reform and Control Act of 1986.

     (d) Except as set forth on Schedule  3.12(d),  Seller has not  received any
notice from any Employee  regarding his intent to terminate his employment  with

forth on Schedule 3.12(d) and subject to general  principles related to wrongful
termination  of  employees,  the  employment  of each  Employee of the Seller is
terminable at the will of the Seller.  Except as set forth on Schedule  3.12(d),
no  employee  of the  Seller  is a party  to,  or is  otherwise  bound  by,  any

          the operation of the Procuren Operations,  the ownership or use of the
          Product,  or the ownership or use of any of the other  Assets,  unless
          the  failure  to comply  would not be  reasonably  expected  to have a
          material  adverse  effect on the  financial  condition of the Procuren
          Operations or the Assets;

          modify, any Governmental Authorization that is held by Buyer; or

     condition of Buyer.

Section 4.3       Certain Proceedings.

                  There are no Proceedings  pending or Orders outstanding (i) by
or against Buyer that could  reasonably be expected to materially  and adversely
affect the  operations or financial  condition of Buyer and its  Affiliates;  or
(ii) that challenge, or that may have the effect of preventing, delaying, making
illegal or otherwise interfering with, any of the Contemplated Transactions.  To
the Knowledge of Buyer, no such Proceeding has been threatened.

Section 4.4       Financial Statements.

                  Buyer   acknowledges   that   Seller  has   relied   upon  the
consolidated financial information of Cytomedix,  Inc. filed with the Securities
and Exchange  Commission in  compliance  with its  reporting  requirements  as a
public  company for the calendar  year 2000 and for the calendar year ended 1999
(such financial information, the "Buyer Public Financial Statements"). The Buyer
Public Financial  Statements fairly present financial  condition and the results
of operations,  changes in shareholders'  equity,  and cash flows of Buyer as at
the  respective  dates  of and for the  periods  referred  to in such  financial
statements,  all in accordance with GAAP. The Buyer Public Financial Statements,
reflect the consistent  application of such accounting principles throughout the
periods involved, except as disclosed in the notes to such financial statements.

Section 4.5       Brokers or Finders.

                  Neither Buyer nor any of its officers, directors, employees or

commissions  or other  similar  payment  in  connection  with  the  Contemplated
Transactions.

Section 4.6       No Material Adverse Change.

                  Since the date of the 10-Q of  Cytomedix,  Inc. for the second
quarter of 2000 (the "Cytomedix 10-Q"),  there has not been any material adverse
change with respect to the  operations  or financial  condition of Buyer and its
Affiliates,  and no  event  has  occurred  or  circumstance  exists  that  could
reasonably be expected to result in such a material adverse change.

Section 4.7       No Undisclosed Liabilities.

                  Except as set forth in Schedule  4.7,  Buyer has no  Liability
except  for (a)  Liabilities  reflected  or  reserved  against  in  consolidated
financial  information  of Buyer in the Cytomedix 10-Q filed with the Securities
and  Exchange  Commission  or (b) current  liabilities  incurred in the Ordinary
Course of Business of Seller since the date of the Cytomedix 10-Q.

Section 4.8       Solvency.

                  Buyer is not now insolvent, and will not be rendered insolvent
by any of the Contemplated Transactions.  In addition,  immediately after giving
effect to the consummation of the Contemplated  Transactions,  (a) Buyer will be
able to pay its debts as they become due,  (b) Buyer will not have  insufficient
assets or resources  with which to conduct its present or proposed  business and
(c) taking into account all pending and threatened  litigation,  final judgments
against Buyer in actions for money damages are not reasonably  anticipated to be

satisfy any such judgments  promptly in accordance with their terms (taking into
account the maximum  probable  amount of such  judgments in any such actions and
the earliest  reasonable  time at which such judgment might be rendered) as well
as all other  obligations of Buyer.  The cash  available to Buyer,  after taking
into account all other  anticipated  uses of the cash, will be sufficient to pay
all such debts and judgments promptly in accordance with their terms. As used in
this  Section  4.8,  (i)  "insolvent"  means  that the sum of the  present  fair
saleable  value of the Buyer's assets does not and will not exceed its debts and
other  probable  liabilities,  and (ii) "debts"  includes  any legal  liability,
whether matured or unmatured,  liquidated or  unliquidated,  absolute,  fixed or
contingent,  disputed or undisputed or secured or unsecured.  Buyer acknowledges
and agrees that,  after giving effect to the  transactions  contemplated by this
Agreement, the Purchase Price is reasonably equivalent value for the Assets.

                  By written notice given prior to or at the Closing, subject to

     satisfaction  of such a  condition  by such date is or  becomes  impossible
     (other than  through  the  failure of Buyer to comply with its  obligations
     under this  Agreement) and Buyer has not waived such condition on or before
     such date;

     (d) by Seller,  if any condition in Article VIII has not been  satisfied as
     of the date  specified for Closing in the first  sentence of Section 2.6 or
     if satisfaction  of such a condition by such date is or becomes  impossible
     (other than  through  the failure of Seller to comply with its  obligations

     (e) by mutual consent of Buyer and Seller;

     (f) by Buyer if the Closing  has not  occurred  on or before  February  12,

                  Each  party's  right of  termination  under  Section 9.1 is in
addition to any other rights it may have under this Agreement or otherwise,  and
the exercise of such right of  termination  will not be an election of remedies.

parties under this Agreement will terminate,  except that the obligations of the
parties in this Section 9.2 and Articles XII will  survive;  provided,  however,
that if this  Agreement is terminated  because of a Breach of this  Agreement by
the  non-terminating  party  or  because  one or more of the  conditions  to the
terminating  party's  obligations  under this  Agreement  is not  satisfied as a
result  of the  party's  failure  to  comply  with its  obligations  under  this
Agreement,  the  terminating  party's  right to pursue all legal  remedies  will
survive such termination unimpaired.

                                   ARTICLE X.
                              ADDITIONAL COVENANTS

Section 10.1      Employees and Employee Benefits.

     (a) All of the Employees  will be available for hiring by Buyer pursuant to
     the  provisions  of this  Section  10.1.  Seller  will  provide  Buyer  (i)
     reasonable access to Personnel Records relating to the Employees,  and (ii)
     reasonable  access to the  Facilities  for the purpose of allowing Buyer to
     interview any Employees  that Buyer desires to interview.  Buyer shall make
     offers of employment to all of the Employees at a base salary for each such
     Employee  equal to or greater than the base salary paid to such Employee by
     Seller  as of the date of this  Agreement,  and  shall  not  terminate  the
     employment of any Hired  Employee (as defined below) except for cause for a
     period of sixty (60) days  following the Closing Date.  Buyer will promptly
     provide  Seller  a list of  Employees  to whom  Buyer  has made an offer of
     employment  that has been  accepted to be effective on or after the Closing
     Date (the  "Hired  Employees").  Effective  immediately  before the Closing
     Date,  Seller shall terminate the employment of all of such Hired Employees
     and  shall  release  such  Hired  Employees  from  the  provisions  of  any
     restrictive  covenants and/or  agreements with Seller with respect to Buyer
     so as to enable Buyer to employ such individuals.  Seller shall not solicit
     the employment of, or attempt to retain, any Employee;  provided,  however,
     that Seller may solicit the  employment  of any Employee who is not a Hired
     Employee.  In the event Buyer breaches any of its  obligations set forth in
     this Section 10.1(a) with respect to any Employee, the maximum liability of
     Buyer to Seller hereunder shall be the amount of Seller's liability to such
     Employee  under  Seller's  Severance  Plan Document dated November 15, 1999
     (the "Severance  Plan").  Except for the requirement to offer employment to
     the Employees at the same or greater base salary, nothing contained in this
     Section  10.1(a) shall require Buyer's offer of employment to be on similar
     terms or conditions as that Employee  enjoyed with Seller,  and Buyer shall
     have  discretion  regarding all other terms and  conditions of  employment,
     including  but not limited to employee  benefits  with respect to the Hired
     Employees.

     (b) It is  understood  and  agreed  that (i) except as set forth in Section
     10.1(a) above,  Buyer's expressed  intention to extend offers of employment
     as set forth in this  Section  10.1 shall not  constitute  any  commitment,
     Contract or  understanding  (expressed or implied) of any obligation on the
     part of Buyer to a post-Closing  Date employment  relationship of any fixed
     term or  duration  or upon any terms or  conditions  other  than those that
     Buyer may  establish  pursuant to  individual  offers of  employment,  (ii)
     except as set forth in Section 10.1(a) above,  employment  offered by Buyer
     is "at will" and may be  terminated  by Buyer or by an employee at any time
     for any reason (subject to any written  commitments to the contrary made by
     Buyer  specifically to such individual),  and (iii) if Buyer fails to offer
     employment to any Employee of Seller on  substantially  the same or greater
     base salary at the rate paid by Seller,  such Employee may become  eligible
     to  receive  termination  or  severance  payments  from  Seller  under  the
     Severance Plan.  Except as set forth in Section  10.1(a) above,  nothing in
     this Agreement  shall be deemed to prevent or restrict in any way the right
     of Buyer  to  terminate,  reassign,  promote  or  demote  any of the  Hired
     Employees  after the Closing,  or to change  (adversely or  favorably)  the
     title, powers, duties,  responsibilities,  functions,  locations, salaries,
     other  compensation  or terms or  conditions  of  employment  of the  Hired
     Employees.

     (c) Seller shall be responsible  for (i) the payment of all wages and other
     remuneration  due to its  employees  with  respect  to  their  services  as
     employees of Seller through the close of business on the Closing Date, (ii)
     the payment of any  termination or severance  payments and the provision of
     health plan  continuation  coverage in accordance with the  requirements of
     COBRA, and (iii) any and all payments to employees  required under the WARN
     Act.  Seller  shall  be  liable  for any  claims  made or  incurred  by the
     Employees  and their  beneficiaries  through  the  Closing  Date  under the
     Employee Benefit Plans. For purposes of the immediately preceding sentence,
     a claim will be deemed incurred, in the case of medical or dental benefits,
     when the services that are the subject of the charge are performed,  in the
     case of hospital benefits,  when the individual entered the hospital,  and,
     in the case of other benefits (such as disability or life insurance),  when
     an event has occurred or when a condition has been diagnosed which entitles
     the employee to the benefit.


     (d)  Seller  and Buyer  shall  give any  notices  required  by law and take
     whatever  other  actions with  respect to the plans,  programs and policies
     described  in  this  Section  10.1 as may be  necessary  to  carry  out the
     arrangements described in this Section 10.1.

     (e) Seller and Buyer shall provide each other with such plan  documents and
     summary plan  descriptions,  employee data or other  information  as may be
     reasonably required to carry out the arrangements described in this Section
     10.1.

     (f) Buyer shall not have any  responsibility,  liability or obligation,  to
     the  Employees or to any other Person with respect to any Employee  Benefit
     Plan maintained by Seller.

     (g) No  provision  of this  Section  10.1  shall  create  any  third  party
     beneficiary or other rights in any employee or former  employee  (including
     any  beneficiary  or  dependent  thereof)  of  the  Seller  or  any  of its
     Subsidiaries  in respect of continued  employment  (or resumed  employment)
     with the Buyer and no  provision of this Section 10.1 shall create any such
     rights in any such persons in respect of any benefits that may be provided,
     directly  or  indirectly,  under  any  Employee  Benefit  Plans or any such
     similar plan or arrangement that may be established by the Buyer.


Section 10.2  Payment of All Taxes Resulting From Sale of Assets by Seller.

                  Seller shall pay in a timely manner all Taxes  resulting  from
or payable in connection with the sale of the Assets pursuant to this Agreement,
regardless  of the Person on whom such Taxes are imposed by Legal  Requirements;
provided, however, that Buyer shall reimburse Seller for all sales and use taxes
resulting from or payable in connection  with the sale of the Assets pursuant to
this Agreement to the extent such taxes do not exceed $200,000.

Section 10.3      Payment of Other Retained Liabilities.

                  In  addition  to payment of Taxes  pursuant  to Section  10.2,
Seller shall pay, or make adequate provision for the payment,  in full of all of
the Retained Liabilities relating to the Procuren Operations.

Section 10.4      Reports and Returns.

                  Seller shall promptly  after the Closing  prepare and file all
reports and returns  required by applicable Legal  Requirements  relating to the
Procuren Operations.

Section 10.5      Insurance.

                  For six  (6)  years  after  the  Closing  Date,  Seller  shall
continue to maintain product liability  insurance with respect to Assets insured
as of the Closing Date providing substantially the same coverage as in effect on
the date hereof or insurance  that is  comparable  to the policy  maintained  by
Buyer  from  time to time  and  Seller  shall  cause  Buyer  to be  named  as an
additional insured on each such policy.

Section 10.6      Further Assurances.

                  The parties  shall  cooperate  reasonably  with each other and
with their respective  Representatives  in connection with any steps required to
be taken as part of their respective  obligations under this Agreement,  and the
parties agree (a) to furnish upon reasonable  request to each other such further
information,  (b) to execute and deliver to each other such other documents, and
(c) to do such  other acts and  things,  all as the other  party may  reasonably
request  for the purpose of carrying  out the intent of this  Agreement  and the
Contemplated  Transactions.  In the event  that  Seller  inadvertently  does not
deliver any of the Assets at Closing,  Buyer agrees that it shall bring no claim
against Seller if (a) Seller promptly  delivers such Assets upon notice thereof,
and (b) Buyer has suffered no Damages  arising out of or in connection with such
lack of delivery at Closing.

Section 10.7      Access to Patient Data Base of Seller.

                  From and after the  Closing  Date  until  such time that Buyer
receives FDA approval of the Product or terminates the clinical trial  conducted
in contemplation of receiving FDA approval,  Seller shall, upon reasonable prior
notice by Buyer,  provide Buyer and its  Representatives  with all de-identified
data  reasonably  requested by Buyer with respect to the full MediLink data base
and all other  information  of Seller used in  connection  with the treatment of
patients (including any data on client use and experience with the Product), for
use by Buyer in connection with (a) any clinical  trials  involving the Product,
or (b) any support  and  marketing  services  provided  by Buyer  involving  the
Product in any jurisdiction in which the provision of such services is legal.

Section 10.8      Cooperation in the Event of FDA Action.

                  In the event that,  after the Closing  Date the FDA issues any
Warning  Letters  or other  notifications  to Buyer,  or  otherwise  brings  any
Proceeding  against  Buyer,  as the  result  of  events  occurring  prior to the
Closing,   Seller  shall   cooperate  with  Buyer  in  responding  to  any  such
notification or Proceeding.  Nothing  contained  herein affects Buyer's right to
indemnification as set forth in Article XI.

Section 10.9      Audited Financial Statements.

                  In the event that after the Closing Date, Buyer determines, in
its reasonable  discretion,  that in connection with its obligations as a public
company it needs audited financial  information with respect to the operation of

of Buyer,  use its reasonable  efforts to cause such financial  statements to be
prepared by Ernst & Young.

assignment of the BTG Agreement to Cytomedix GmbH at or prior to Closing, Seller
shall,  at the expense of Cytomedix  GmbH and as Cytomedix  GmbH may  reasonably
request,  enforce the  provisions of such agreement for the benefit of Cytomedix

Section 11.1      Survival.

                  All representations, warranties, covenants, and obligations in
this  Agreement,  the Schedules  attached  hereto,  the  certificates  delivered
pursuant  to  Section  2.7,  and any other  certificate  or  document  delivered
pursuant to this Agreement shall survive the Closing and the consummation of the
Contemplated Transactions. The right to indemnification, reimbursement, or other
remedy based on such  representations,  warranties,  covenants  and  obligations
shall not be affected by any  investigation  conducted  with  respect to, or any
knowledge  acquired  (or  capable of being  acquired)  about,  the  accuracy  or
inaccuracy of or compliance with, any such representation, warranty, covenant or
obligation.   The  waiver  of  any  condition  based  on  the  accuracy  of  any
representation  or warranty,  or on the  performance  of or compliance  with any
covenant  or  obligation,   will  not  affect  the  right  to   indemnification,
reimbursement,  or  other  remedy  based  on such  representations,  warranties,
covenants,  and  obligations.  The  right to  indemnification  provided  in this
Article  XI shall be the  exclusive  remedy  of the  parties  hereto;  provided,
however,  that the foregoing  restriction  shall not limit claims for injunctive
relief or  specific  performance  (including,  without  limitation,  claims  for
specific  performance  pursuant  to  Section  2.1)  or  claims  based  upon  the
fraudulent misconduct of the other party.

Cytomedix GmbH, their respective  Representatives  and  shareholders,  and their
respective Related Persons (collectively,  the "Buyer Indemnified Persons"), and
shall reimburse the Buyer Indemnified Persons, for any loss,  liability,  claim,
damage,  expense  (including costs of  investigation  and defense and reasonable
attorneys' fees and expenses) or diminution of value, whether or not involving a
third-party claim (collectively, "Damages"), arising from or in connection with:

     (a) any Breach of any  representation  or  warranty  made by Seller in this
     Agreement  (without  giving  effect to any  supplement  to the Schedules to
     Article III), the certificates  delivered pursuant to Section 2.7 (for this
     purpose,  each such certificate will be deemed to have stated that Seller's
     representations  and warranties in this Agreement  fulfill the requirements
     of  Section  7.1 as of the  Closing  Date as if made  on the  Closing  Date
     without  giving  effect to any  supplement to the Schedules to Article III,
     unless the  certificate  expressly  states that the matters  disclosed in a
     supplement  have  caused a  condition  specified  in Section  7.1 not to be
     satisfied),  any transfer  instrument or any other  certificate or document
     delivered by Seller pursuant to this Agreement;

     (b) any Breach of any covenant or obligation of Seller in this Agreement or
     in any other document,  writing or instrument  delivered by Seller pursuant
     to this Agreement;

     in any other document, writing or instrument delivered by Buyer pursuant to
     this Agreement;

     (c) any Liability  arising out or in  connection  with the operation of the
     Procuren Operations after the Closing;

     (d) any Assumed Liabilities;

     (e) Buyer's use of the patient  data base of Seller as set forth in Section
     10.10; or

     (f) the performance of Seller's obligations pursuant to Section 10.11.


 Section 11.4 Time Limitations.

     (a)  If  the  Closing   occurs,   Seller  will  have  no   liability   (for

     foregoing,  any claim with respect to Sections  2.4(c)  (other than a claim

     (b)  If  the   Closing   occurs,   Buyer  will  have  no   liability   (for
     indemnification  (including any contribution) or otherwise) with respect to
     any claim for  Damages  which may be asserted  pursuant to this  Article XI
     unless on or before the second  anniversary  of the  Closing  Date,  Seller
     notifies  Buyer of a claim  specifying  the factual  basis of that claim in
     reasonable detail to the extent then known by Seller.  Notwithstanding  the
     foregoing,  any claim for  indemnification or reimbursement  based upon the
     post-closing  covenants  or  obligations  of Buyer  may be made at any time
     prior to the expiration of the applicable statute of limitations.

Section 11.5 Recoveries.

                  To the extent that an  indemnified  party  receives a recovery
from any third party after being indemnified for such amount by the indemnifying
party,  the  indemnified  party shall  promptly pay the  indemnifying  party the
amount of such  recovery.  In no event  shall the failure of any party to obtain
insurance or the  appropriate  type or amount of  insurance  affect its right to
indemnification hereunder.

Section 11.6      Limitations on Amount - Seller.

     (a) Seller  shall have no liability  (for  indemnification  (including  any
     contribution)  or  otherwise)  with  respect to matters  described  in this

     the total Damages with respect to such matters exceeds  $150,000,  and then
     only for the  amount by which  such  Damages  exceeds  $150,000;  provided,
     however,   that  to  the  extent  Article  III  contains  any   materiality
     qualifications,  such  materiality  qualifications  will not be taken  into
     account in  determining  the  magnitude  of the Damages  occasioned  by the
     Breach for purposes of  calculating  whether they are applied to the basket
     set forth above.  Notwithstanding the foregoing,  this Section 11.6(a) will
     not apply to matters arising in respect of Sections 2.1.


     (b) Seller  shall have no liability  (for  indemnification  (including  any
     contribution)  or otherwise) with respect to matters  described in Sections
     11.2(a)  or 11.2(b) to the extent  that all  Damages  with  respect to such
     matters   exceeds   $1,150,000.   Seller  shall  have  no  liability   (for

     (a) Buyer  shall have no  liability  (for  indemnification  (including  any
     contribution)  or  otherwise)  with  respect to matters  described  in this
     Article XI until the total of all  Damages  with  respect  to such  matters
     exceeds $300,000, and then only for the amount by which such Damages exceed
     $150,000;  provided,  however,  that to the extent Article III contains any
     materiality  qualifications,  such materiality  qualifications  will not be

     basket set forth above.

     (b) Buyer  shall have no  liability  (for  indemnification  (including  any

     matters exceeds  $1,150,000.  Notwithstanding  the foregoing,  this Section
     11.7(b) will not apply to matters  arising in respect of Sections 4.4 or to
     any Breach of any of Buyer's  representations  and  warranties of which the
     Buyer  had  Knowledge  at  any  time  prior  to  the  date  on  which  such
     representation  and  warranty  is made,  and Buyer  will be liable  for all
     Damages with respect to such Breaches.

Section 11.8  Procedure for Indemnification - Third Party Claims.

     (a) Promptly  after receipt by an  indemnified  party under Section 11.2 or
     11.3 of notice of the  commencement  of any  Proceeding  against  it,  such
     indemnified  party will,  if a claim is to be made against an  indemnifying
     party  under such  Section,  give notice to the  indemnifying  party of the
     commencement of such Proceeding, but the failure to notify the indemnifying
     party will not relieve the indemnifying  party of any liability that it may
     have to any indemnified  party,  except to the extent that the indemnifying
     party  demonstrates  that the defense of such action is  prejudiced  by the
     indemnified party's failure to give such notice.

     (b) If an indemnified  party gives notice to the indemnifying  party of the
     commencement  of  a  Proceeding   referred  to  in  Section  11.8(a),   the
     indemnifying  party will be entitled to participate in such Proceeding and,
     to the extent that it wishes to assume the defense of such  Proceeding with
     counsel  satisfactory to the  indemnified  party and, after notice from the
     indemnifying  party to the indemnified  party of its election to assume the
     defense of such Proceeding,  the indemnifying party will not, as long as it
     diligently  conducts such defense, be liable to the indemnified party under
     this Article XI for any fees of other  counsel or any other  expenses  with
     respect  to the  defense  of such  Proceeding,  in each  case  subsequently
     incurred by the  indemnified  party in connection  with the defense of such
     Proceeding,  other than reasonable costs of  investigation  (unless (i) the
     indemnifying  party is also a party to such  Proceeding and the indemnified
     party  determines  in  good  faith  that  joint   representation  would  be
     inappropriate,  or (ii) the indemnifying  party fails to provide reasonable
     assurance to the indemnified party of its financial capacity to defend such
     Proceeding and provide indemnification with respect to such Proceeding). If
     the indemnifying party assumes the defense of a Proceeding,  (x) it will be
     conclusively  established  for purposes of this  Agreement  that the claims
     made  in  that   Proceeding   are  within  the  scope  of  and  subject  to
     indemnification;  (y) no  compromise  or  settlement  of such claims may be
     effected by the indemnifying party without the indemnified  party's Consent
     unless (A) there is no  finding  or  admission  of any  violation  of Legal
     Requirements  or any violation of the rights of any Person and no effect on
     any other claims that may be made against the  indemnified  party,  and (B)
     the sole relief  provided is monetary  damages that are paid in full by the
     indemnifying  party;  and (z) the indemnified  party will have no liability
     with  respect to any  compromise  or  settlement  of such  claims  effected
     without its  Consent.  If notice is given to an  indemnifying  party of the
     commencement of any Proceeding and the indemnifying  party does not, within
     ten (10) days after the indemnified party's notice is given, give notice to
     the  indemnified  party of its  election  to  assume  the  defense  of such
     Proceeding,  the indemnifying party will be bound by any determination made
     in  such  Proceeding  or  any  compromise  or  settlement  effected  by the
     indemnified party.

     (c)  Notwithstanding  the foregoing,  if an indemnified party determines in
     good faith that there is a reasonable  probability  that a  Proceeding  may
     adversely  affect  it or its  Related  Persons  other  than as a result  of
     monetary  damages for which it would be entitled to  indemnification  under
     this Agreement,  the indemnified  party may, by notice to the  indemnifying
     party,  assume the exclusive  right to defend,  compromise,  or settle such
     Proceeding,   but  the  indemnifying   party  will  not  be  bound  by  any
     determination  of a  Proceeding  so  defended  for  the  purposes  of  this
     Agreement or any  compromise  or  settlement  effected  without its Consent
     (which may not be unreasonably withheld or delayed).

     (d) Each party hereby  consents to the  non-exclusive  Jurisdiction  of any
     court in which a Proceeding is brought against any Buyer Indemnified Person
     or Seller Indemnified Person for purposes of any claim that such person may
     have under this  Agreement  with respect to such  Proceeding or the matters
     alleged  therein,  and agree that  process may be served on such party with
     respect to such a claim anywhere in the world.

Section 11.9 Procedure For Indemnification - Other Claims.

                  A claim for  indemnification  for any matter not  involving  a
third-party   claim  may  be   asserted   by  notice  to  the  party  from  whom
indemnification is sought.

                                  ARTICLE XII.
                               GENERAL PROVISIONS

Section 12.1      Confidentiality; Public Announcements.

     (a) Buyer and Seller shall  maintain in  confidence,  and shall cause their
     respective directors, officers, employees, agents, and advisors to maintain
     in  confidence,  and not  use to the  detriment  of the  other  party,  any
     written,  oral, or other  information  obtained in confidence  from another
     party in connection with this Agreement or the  Contemplated  Transactions,
     unless (a) such information is already known to such party or to others not
     bound by a duty of  confidentiality  or such  information  becomes publicly
     available  through no fault of such party,  (b) the use of such information
     is necessary or  appropriate  in making any filing or obtaining any Consent
     required for the consummation of the Contemplated Transactions,  or (c) the
     furnishing  or use of such  information  is  required  by or  necessary  in
     connection with any Proceeding.

     (b) Any public  announcement  or  similar  publicity  with  respect to this
     Agreement or the  Contemplated  Transactions  may be issued,  if at all, at
     such time and in such  manner as  mutually  agreed to by Buyer and  Seller;
     provided,   however,  that  in  the  case  of  announcements,   statements,
     acknowledgments or revelations which either party is required by applicable
     Legal  Requirements  to make,  issue or  release,  the  making,  issuing or
     releasing of any such announcement, statement, acknowledgment or revelation
     by the party so required to do by applicable Legal  Requirements  shall not
     constitute a breach of this  Agreement  if such party shall have given,  to
     the extent reasonably possible,  notice thereof to the other party not less
     than two (2) days prior to such disclosure and shall have attempted, to the
     extent  reasonably  possible,   to  clear  such  announcement,   statement,
     acknowledgment  or  revelation  with  the  other  party.   Subject  to  the
     foregoing,  Seller and Buyer shall consult with each other  concerning  the
     means by which  Seller's  employees,  customers,  and  suppliers and others
     having  dealings  with the  Seller  will be  informed  of the  Contemplated
     Transactions.


Section 12.2 Expenses.

                  Except as otherwise expressly provided in this Agreement, each
party  to  this  Agreement  shall  bear  its  respective  expenses  incurred  in
connection with the  preparation,  execution,  and performance of this Agreement
and the  Contemplated  Transactions,  including  all  fees and  expenses  of its
Representatives.  In the event of termination of this Agreement,  the obligation
of each  party to pay its own  expenses  is  subject to any rights of such party
arising from a Breach of this Agreement by another party.

Section 12.4      Jurisdiction, Service of Process.

                  Any Proceeding arising out of or relating to this Agreement or
any  Contemplated  Transaction  may be brought in the courts of the State of New
York,  County of New York,  or, if it has or can  acquire  jurisdiction,  in the
United  States  District  Court  located  therein,   and  each  of  the  parties
irrevocably submits to the exclusive jurisdiction of each such court in any such
Proceeding,  waives any  objection it may now or  hereafter  have to venue or to
convenience of forum,  agrees that all claims in respect of the Proceeding shall
be heard and  determined  only in any such  court,  and  agrees not to bring any
Proceeding  arising  out of or relating to this  Agreement  or any  Contemplated
Transaction  in any other court.  Process in any  Proceeding  referred to in the
preceding sentence may be served on any party anywhere in the world.

Section 12.5      Enforcement of Agreement.

                  Seller  acknowledges  and agrees  that Buyer  would be damaged
irreparably  in the  event  any of the  provisions  of  this  Agreement  are not
performed in accordance  with their  specific  terms and that any breach of this
Agreement by Seller could not be  adequately  compensated  by monetary  damages.
Accordingly,  Seller  agrees  that,  in addition to any other right or remedy to
which  Buyer may be  entitled,  at law or in  equity,  it shall be  entitled  to
enforce any provision of this Agreement by a decree of specific  performance and
to temporary, preliminary and permanent injunctive relief to prevent breaches or
threatened  breaches of the provisions of this  Agreement,  without  posting any
bond or other undertaking.

Section 12.6      Waiver.

                  The rights and remedies of the parties to this  Agreement  are
cumulative and not  alternative.  Neither the failure nor any delay by any party
in exercising  any right under this  Agreement or the  documents  referred to in
this  Agreement  operates  as a waiver of such  right,  and no single or partial
exercise of any such right precludes any other or further exercise of such right
or  the  exercise  of any  other  right.  To the  maximum  extent  permitted  by
applicable  law,  (a) no claim or right  arising  out of this  Agreement  or the
documents referred to in this Agreement can be discharged by one party, in whole
or in part, by a waiver or  renunciation of the claim or right unless in writing
signed  by the  other  party;  (b) no  waiver  that  may be  given by a party is
applicable  except in the specific  instance  for which it is given;  and (c) no
notice to or demand on one party is deemed to be a waiver of any  obligation  of
such  party or of the right of the party  giving  such  notice or demand to take
further  action  without  notice or demand as provided in this  Agreement or the
documents referred to in this Agreement.

Section 12.7      Entire Agreement and Modification.

                  This Agreement supersedes all prior agreements (including that
certain  Letter of Intent by and between  Cytomedix,  Inc. and  Curative  Health
Services  dated July 17,  2000  (including  any  extensions  thereof),  and that
certain  Confidentiality  Agreement by and between Cytomedix,  Inc. and Curative
Health  Services  dated June 6,  2000),  whether  written or oral,  between  the
parties  with  respect to its  subject  matter and  constitutes  (along with the
Schedules,  Exhibits and other documents delivered pursuant to this Agreement) a
complete  and  exclusive  statement  of the terms of the  agreement  between the
parties with respect to its subject  matter.  This  Agreement may not be amended
except by a written agreement signed on behalf of each of the parties hereto.

Section 12.8      Assignments, Successors, and No Third-Party Rights.

                  No party may assign any of its rights or  delegate  any of its
obligations  under this Agreement without the prior written consent of the other
parties,  except that Buyer may assign any of its rights and delegate any of its
obligations under this Agreement to any Subsidiary of Buyer and may collaterally
assign its rights hereunder to any financial  institution providing financing in
connection with the Contemplated Transactions,  provided that no such assignment
or delegation shall relieve Buyer from any of its obligations hereunder. Subject
to the preceding sentence, this Agreement applies to, is binding in all respects
upon, and inures to the benefit of the  successors and permitted  assigns of the
parties.  Nothing in this  Agreement is to be construed to give any Person other
than the parties to this  Agreement  any legal or equitable  right under or with
respect to this Agreement or any provision of this Agreement, except such rights
as shall inure to a successor  or  permitted  assignee  pursuant to this Section
12.8.

Section 12.9      Severability.

                  If  any  provision  of  this  Agreement  is  held  invalid  or
unenforceable  by any court of competent  jurisdiction,  the other provisions of
this Agreement  remain in full force and effect.  The parties further agree that
if  any  provision   contained  herein  is,  to  any  extent,  held  invalid  or
unenforceable in any respect under the laws governing this Agreement, they shall
take any actions necessary to render the remaining  provisions of this Agreement
valid and enforceable to the fullest extent  permitted by law and, to the extent
necessary,  shall  amend or  otherwise  modify  this  Agreement  to replace  any
provision  contained herein that is held invalid or  unenforceable  with a valid
and enforceable provision giving effect to the intent of the parties.

Section 12.10     Section Headings, Construction, Schedules.

                  The headings of Articles and  Sections in this  Agreement  are

                                  ARTICLE II.
                               ROYALTY OBLIGATIONS

Section 2.1       Amount of Payment.  Cytomedix shall pay royalties to Curative
during the Term as set forth below:

     (a)  Cytomedix  shall pay Curative  three percent (3%) of the aggregate Net
     Sales  Amount of Procuren  (such  amount,  the  "Procuren  Royalty"),  on a
     country by country basis,  in each of the countries  listed on Schedule 2.1
     (the  "Applicable  Countries")  for such  time as any of the  Patents  with
     respect  to such  Applicable  Country  remain  valid,  enforceable,  and in
     effect.  Cytomedix  shall have no further  obligation  to pay the  Procuren
     Royalty in any Applicable  Country at such time when no Patent with respect
     to such Applicable Country remains valid, enforceable and in effect.

     (b)  Cytomedix  shall pay Curative  six percent (6%) (the "Future  Products
     Royalty  Percentage")  of the  aggregate  Net Sales  Amount  of the  Future
     Products  (the "Future  Products  Royalty,"  and together with the Procuren
     Royalty, the "Royalty"),  on a country by country basis, in each Applicable
     Country for such time as any of the Patents with respect to such Applicable
     Country remain valid, enforceable,  and in effect; provided,  however, that
     at such time that the  aggregate  worldwide  Net Sales Amount of the Future
     Products  with respect to which the Future  Products  Royalty has been paid
     since  the   Effective   Date  exceeds  Three   Hundred   Million   Dollars
     ($300,000,000),  the Future Products Royalty Percentage shall thereafter be
     reduced to five percent (5%). Cytomedix shall have no further obligation to
     pay the Future Products Royalty in any Applicable Country at such time that
     no  Patent  with  respect  to  such   Applicable   Country  remains  valid,
     enforceable and in effect.

                  Notwithstanding   the  foregoing,   Cytomedix  shall  have  no
obligation  to pay any  Royalties  to Curative in  connection  with any sales of
Procuren made to Curative or any of its Affiliates pursuant to the terms of that
certain  Supply  Agreement of even date herewith,  by and between  Cytomedix and
Curative  (the  "Supply  Agreement")  until such time,  if any,  that  Cytomedix
receives FDA approval of Procuren.

Section  2.2  Payment of Royalty.
     Cytomedix  shall pay the Royalty  quarterly.  Within  forty-five  (45) days
after the end of each  calendar  quarter,  Cytomedix  shall (a) pay Curative the
amount of the Royalty  owed by  Cytomedix  for such  calendar  quarter,  and (b)
provide  Curative with a written  report setting forth the Net Sales Amount with
respect to Procuren and the Future Products for the applicable quarter,  and the
computation of the Procuren Royalty and the Future Products Royalty with respect
thereto for the applicable quarter.  The Royalty shall be payable in currency of
the United States of America regardless of the country where earned and shall be
paid or deposited as designated  in writing by Curative.  The exchange rate used
to  calculate  the  Royalty  shall be the same rate  specified  under  Financial
Accounting Standards Board Statement 52, or its successor, used to translate the
financial  results of Cytomedix or its Affiliates for public  reporting.  If the
Royalty for the previous  calendar quarter remains unpaid within forty-five (45)
days  after the end of such  calendar  quarter,  interest  shall  accrue on such
unpaid amount at the lower of (a) fifteen  percent  (15%) per annum,  or (b) the
highest rate permitted by law, until paid.

Section 2.3 No Other Compensation.
     Except as expressly provided herein,  Curative is not entitled to any other
compensation from Cytomedix or any other third party in connection with the sale
of Procuren and the Future Products and shall receive no royalty on sales of any
other product of Cytomedix.

Section  2.4 Records and Reports;  Audits.
     Cytomedix  shall  keep  true and  accurate  records  and  books of  account
containing  information  necessary for the  determination of the Royalty payable
hereunder.  These records and books of account shall upon  reasonable  notice be
available  during  business hours for inspection by Curative.  Curative shall be
entitled to conduct an audit,  upon thirty  (30) days' prior  written  notice to
Cytomedix,  of such books and records.  Curative may engage an independent third
party auditor to conduct such audits.  Cytomedix  shall be entitled to receive a
copy of any audit reports produced by or on behalf of Curative hereunder. In the
event any such  audit  reveals a greater  than  five  percent  (5%)  discrepancy
between  the  correct  amount  of the  Royalty  which  should  have been paid by
Cytomedix  pursuant to the terms herein during the period  covered by such audit
and the actual  amount of the Royalty  paid by  Cytomedix  during  such  period,
Cytomedix shall reimburse Curative for the costs of such audit.

Section 2.5 Milestones.  Cytomedix covenants that it shall:

     (a)  submit a request to the FDA for a pre-IND  (Investigational  New Drug)
     application  meeting for  Procuren  within  three (3) months of the Closing
     Date;

     (b) initiate a clinical  trial for Procuren  within 180 days of the release
     of any  Institutional  Review Board,  or State or Federal  agency  clinical
     holds subsequent to filing the IND;

     (c) submit a Biologics License Application (BLA) for Procuren to FDA within
     twelve (12) months of completing a successful Phase III clinical trial;

     (d) make reasonable efforts to commercialize  Procuren in the United States
     within four (4) months of receiving final FDA approval of the BLA; and

     (e) upon termination of that certain  Commercialization  Agreement dated as
     of January 19, 1998 (the "BTG Agreement"),  by and between Curative and BTG
     USA Inc., a Delaware corporation, and successful completion of the transfer
     of all data gathered  under the BTG Agreement to Cytomedix,  Cytomedix will
     use reasonable efforts to initiate pre-clinical animal studies to determine
     the  feasibility  of using  platelet  factor 4 derived  peptides to promote
     wound healing.


Section  2.6  Offset.
     Notwithstanding any other provision in this Agreement or the Asset Purchase
Agreement,  upon notice to Curative,  Cytomedix  may set off any amounts owed by
Cytomedix to the  University of Minnesota or any successor in interest  pursuant
to that certain  Second  Curatech - University of Minnesota  Research  Agreement
dated as of September 30, 1988 against any amounts otherwise payable to Curative
under this Agreement;  provided,  however, that the amount of such set-off shall
not reduce (a) the Procuren Royalty  Percentage  (after taking into account such
set-off) below one and one-half  percent (1.5%) for any payment period,  and (b)
the Future Products Royalty  Percentage (after taking into account such set-off)
below four and one-half percent (4.5%) for any payment period,  or, in the event
the Future Products Royalty  Percentage has been reduced to five percent (5%) as
set forth in Section 2.1(b) above,  below three and one-half  percent (3.5%) for
any payment  period.  The exercise of such right of set-off by Cytomedix in good
faith, whether or not ultimately determined to be justified, will not constitute
an event of default under this Agreement.

                                  ARTICLE III.
                                TERM; TERMINATION

Section  3.1  Term.
This  Agreement  commences  upon  the  Effective  Date  and
terminates  at such time when  Cytomedix  has no further  obligation  to pay any
Royalties pursuant to Section 2.1 (the "Term").

Section  3.2  Termination.
     Upon thirty (30) days' prior  written  notice to  Curative,  Cytomedix  may
terminate  this Agreement if Curative  breaches any of its material  obligations
hereunder  pursuant  to Section  5.2 and fails to cure such breach by the end of
such  thirty (30) day  period,  or, if the parties  agree that the breach is not
capable of being  cured or  remedied  within  thirty  (30) days,  then  within a
timeframe mutually agreed upon by the parties.

Section  3.3
     Remedies upon  Termination.  Termination of this Agreement  shall not limit
either  party  from  pursuing  any other  remedies  otherwise  available  to it,
including, without limitation, injunctive relief.

Section 3.4 Effect of Termination.
     In the event of notice of termination, each party shall continue to perform
its  obligations  hereunder  up to the date of  termination.  Upon  termination,
except as otherwise  provided herein,  the obligations of the parties  hereunder
shall cease and Cytomedix  shall pay Curative any amounts then owing  hereunder;
provided  however,  that in the event of termination due to a breach by Curative
of Section  5.2,  Cytomedix  shall have no right to offset  any  payment  due to
Curative under Section 2.1.

                                   ARTICLE IV.
                                 CONFIDENTIALITY

                  Each party  acknowledges  that any information  concerning the
other  party  received  in  connection  with  this  Agreement  shall  be  deemed
"Confidential and Proprietary  Information" (provided that information contained
within the Assets (as defined in the Asset  Purchase  Agreement)  transferred to
Cytomedix  shall not be  deemed  Confidential  and  Proprietary  Information  of
Curative).  Each party agrees that it shall not permit the  duplication,  use or
disclosure of any such Confidential and Proprietary Information to any person or
entity  (other than its own  employees or agents who must have such  information
for any proper  purpose),  unless (a)  authorized  in writing  and signed by the
other party, or (b) legally required to disclose such information, provided that
the party  availing  itself of this  exception  has promptly  notified the other
party of such required  disclosure and has used commercially  reasonable efforts
to  lawfully  avoid or  limit  such  disclosure.  Confidential  and  Proprietary
Information  does not include any information  which, at the time of disclosure,
is generally known by the public through no breach of the disclosing  party. The
provisions of this Article IV shall survive the  expiration  or  termination  of
this Agreement.

                                   ARTICLE V.
                              INTELLECTUAL PROPERTY

Section 5.1 Right to Defend.
At the election and expense of  Cytomedix,  Cytomedix  shall have the sole right
(but not the obligation,  except as otherwise set forth in Section 5.3 below) to
protect all  intellectual  property  rights  related to Procuren  and the Future
Products,  by obtaining and maintaining  appropriate  patent,  trademark,  trade
secret  or other  rights.  Curative  agrees  to  cooperate,  at the  expense  of
Cytomedix,  in the filing and  prosecution of patent  applications in the United
States  and in  foreign  countries  in  connection  with all  such  intellectual
property rights, and to promptly notify Cytomedix of any conflicting uses of, or
any applications or registrations to use, any mark, name, symbol, device or word
that becomes known to Curative that Curative  believes may  constitute an act of
infringement  with  respect  to the  intellectual  property  rights  related  to
Procuren and the Future Products.

Section 5.2 Ownership of  Intellectual  Property.
     Curative  acknowledges  that, subject to Article VI, neither this Agreement
     nor the performance of its obligations hereunder shall affect the ownership
     by Cytomedix of any of the goodwill or intellectual property rights related
     to Procuren or the Future Products, and such goodwill or other rights shall
     be and remain in the name of Cytomedix.  Curative warrants that, subject to
     Article  VI, it shall not at any time (a) do or cause to be done any act or
     thing  contesting  or in any way impairing or tending to impair any part of
     such ownership and/or rights, or (b) represent that it has any ownership in
     Procuren or the Future  Products  or any  intellectual  property  rights in
     connection  therewith.  Section 5.3  Enforceability  of Patents.  Cytomedix
     shall use its Best  Efforts to ensure  that the  Patents  remain  valid and
     enforceable.
                                  ARTICLE VI.
                                SECURITY INTEREST

Section 6.1 Security Interest.
     Subject to the applicable terms and conditions of this Agreement, Cytomedix
hereby  assigns  and  grants to  Curative  a security  interest  (the  "Security
Interest") in and a lien on the Patents (the "Collateral") to secure the payment
and  the   performance   of  the  following   obligations   (collectively,   the
"Obligations"):

               (a) the payment of the Royalty; and

               (b)  all  reasonable   costs  incurred  by  Curative  to  obtain,
               preserve,  perfect and enforce the  provisions of this Article VI
               and the Security Interest created hereby, collect the Royalty and
               maintain and preserve the  Collateral,  including but not limited
               to taxes, assessments,  insurance premiums,  repairs,  reasonable
               attorney's fees and legal expenses, and expenses of sale.

Section 6.2 Ownership of  Collateral.
     Cytomedix shall defend the Collateral against all claims and demands of all
persons at any time  claiming any  interest  therein  adverse to Curative  which
arises out of or relates to any occurrence or event  happening after the Closing
(as  defined  in the Asset  Purchase  Agreement)  and  Cytomedix  shall keep the
Collateral free from all liens and security interests.


Section  6.3  Costs  of  Curative.
     Cytomedix  shall pay all reasonable  costs  necessary to obtain,  preserve,
perfect, defend and enforce the Security Interest, collect the Obligations,  and
preserve, defend, enforce and collect the Collateral,  including but not limited
to taxes, assessments,  insurance premiums,  repairs, reasonable attorney's fees
and legal expenses,  and expenses of sale. Without waiving  Cytomedix's  default
for failure to make any payment owed hereunder, Curative may, at its option, pay
any such costs and expenses and discharge  encumbrances on the  Collateral,  and
such payment shall be part of the Obligations; provided, that Curative shall not
take any such action  unless it has  requested  Cytomedix to take such action in
writing and  Cytomedix  has not taken such action  within thirty (30) days after
its receipt of such request.  Cytomedix shall  reimburse  Curative on demand for
any costs so incurred.


Section 6.4 Event of Default.
     The happening of any one or more of the following listed events constituted
an event of default (an "Event of Default") by Cytomedix:

               (a) Cytomedix  fails to pay the Royalty owed  hereunder  when due
               and does not cure such  non-payment  within  ninety  (90) days of
               written notice thereof by Curative; or

               (b)  Cytomedix  fails  to meet  the  Milestones  as set  forth in
               Section 2.5.


Section 6.5  Remedies of Curative  Upon  Default.
     Remedies of  Curative  Upon  Default.  Upon the  occurrence  of an Event of
Default,  Curative may, upon giving  fifteen (15) days written notice thereof to
Cytomedix,  Cytomedix N.V., and Cytomedix, Inc., and after such parties have not
cured such  Events of Default  within the fifteen  (15) day period,  declare the
Obligations in whole or part immediately due and may enforce payment of the same
and  exercise  any rights  under the Uniform  Commercial  Code as enacted in the
State of New York, rights and remedies under this Agreement,  or otherwise.  For
purposes of this Section 6.5, to the extent the Event of Default is triggered by
any  failure to meet a time  deadline,  such time  deadline  is to be treated as
extended until the end of such fifteen (15) day period for purposes of any cure.
If Curative chooses to exercise its rights to take possession and dispose of the
Collateral in a commercially  reasonable  manner,  Cytomedix is still liable for
any  unpaid  Obligations  and  is  entitled  to any  surplus  in  excess  of the
Obligations.  If Curative  chooses to exercise its rights to take possession and
retain the Collateral in full satisfaction of the Obligations,  Cytomedix is not
liable for any unpaid  Obligations  and is  entitled to any surplus in excess of
the  Obligations,  such  surplus as mutually  determined  by the parties in good
faith.

                                  ARTICLE VII.
                                  MISCELLANEOUS

Section 7.1 No Joint  Venture.
     Nothing herein shall create any association,  partnership, joint venture or
agency relationship between the parties hereto or any third party.

Section 7.2 Further Assurances.
     The parties shall  cooperate  reasonably with each other in connection with
any steps  required to be taken as part of their  respective  obligations  under
this Agreement,  and the parties agree (a) to furnish upon request to each other
such  further  information,  (b) to execute and deliver to each other such other
documents,  and (c) to do such other acts and things, all as the other party may
reasonably request for the purpose of carrying out the intent of this Agreement.

Section 7.3 Notices.
     All  notices,  consents,  waivers,  and  other  communications  under  this
Agreement  must be in  writing  and are  deemed to have been duly given when (a)
delivered by hand with written  confirmation  of receipt,  (b) sent by facsimile

Section 7.4 Waiver .
     The rights and remedies of the parties to this Agreement are cumulative and
not  alternative.  Neither the failure nor any delay by any party in  exercising
any right under this Agreement operates as a waiver of such right, and no single
or partial exercise of any such right precludes any other or further exercise of
such right or the exercise of any other right.  To the maximum extent  permitted
by applicable  law, (a) no claim or right  arising out of this  Agreement can be
discharged by one party, in whole or in part, by a waiver or renunciation of the
claim or right unless in writing  signed by the other party;  (b) no waiver that
may be given by a party is applicable  except in the specific instance for which
it is  given;  and (c) no  notice  to or  demand  on one party is deemed to be a
waiver of any  obligation of such party or of the right of the party giving such
notice or demand to take further  action without notice or demand as provided in
this Agreement.

Section  7.5  Entire  Agreement  and  Modification.
     This  Agreement,  the Asset  Purchase  Agreement  and the Supply  Agreement
constitute the entire agreement  between the parties with respect to the subject
matter of this Agreement and supersede all prior written and oral agreements and
understandings  between the parties with  respect to the subject  matter of this
Agreement.  This  Agreement  may not be  amended  except by a written  agreement
signed on behalf of each of the parties hereto.

Section 7.6 Assignment.
     Except as set forth above, no party to this Agreement may assign, transfer,
or otherwise  dispose of any of its rights,  duties,  or  obligations  hereunder
without the prior written consent of the other party hereto;  provided,  however
that upon prior written notice to the other party,  (a) either party may assign,
transfer,  or  otherwise  dispose of any of its  rights,  duties or  obligations
hereunder  to any of its  Affiliates  without the consent of the other party (in
which case the assigning  party shall continue to be liable for its  obligations
hereunder),  and (b) Curative may assign its right to receive the Royalty to any
third party without the consent of Cytomedix,  provided that no such  assignment
or delegation pursuant to clauses (a) or (b) shall relieve either party from any
of its obligations hereunder.  Subject to the foregoing, this Agreement shall be
binding  upon and shall  inure to the  benefit of the  parties  hereto and their
permitted successors and assigns.

Section 7.7 Severability.
     If any provision of this Agreement is held invalid or  unenforceable by any
court of competent  jurisdiction,  the other provisions of this Agreement remain
in full force and  effect.  The  parties  further  agree  that if any  provision
contained herein is, to any extent, held invalid or unenforceable in any respect
under the laws governing this Agreement,  they shall take any actions  necessary
to render the remaining  provisions of this Agreement  valid and  enforceable to
the fullest extent permitted by law and, to the extent necessary, shall amend or
otherwise  modify this Agreement to replace any provision  contained herein that
is held invalid or unenforceable  with a valid and enforceable  provision giving
effect to the intent of the parties.

Section 7.8 No Third Party Beneficiary.
     No provision of this Agreement  shall create,  or be deemed to create,  any
legal or equitable right in any person not a party to this Agreement or give any
such person any claim against any party to this  Agreement that such party would
not have but for this Agreement.

Section 7.9 Section  Headings;  Construction.
     The headings of Articles and  Sections in this  Agreement  are provided for
convenience  only and will not affect its  construction or  interpretation.  All
words used in this Agreement will be construed to be of such gender or number as

all cases,  according  to its fair  meaning,  and not for or  against  any party
hereto. The parties  acknowledge that each party has reviewed this Agreement and
that rules of construction to the effect that any ambiguities are to be resolved
against the drafting party shall not be available in the  interpretation of this
Agreement.

Section  7.10  Governing  Law; Jurisdiction.
     This  Agreement  is to be governed by and  construed  under the laws of the
State of New York  without  regard to conflicts  of laws  principles  that would
require the  application  of any other law. The parties agree that the state and
federal courts located in New York County,  New York shall be the sole venue and
shall  have  sole  jurisdiction  for  the  resolution  of all  disputes  arising
hereunder.

                         TRANSITIONAL SERVICES AGREEMENT

                  This  Transitional  Services  (the  "Agreement"),  is made and
entered into as of  ______________,  2000 (the "Effective Date"), by and between
Cytomedix,  Inc., a Delaware  corporation  ("Cytomedix"),  and  Curative  Health
Services, Inc., a Minnesota corporation ("Curative").

                                   WITNESSETH:

                  WHEREAS,  Cytomedix  and  Curative are parties to that certain
Asset  Purchase  Agreement  dated as of October 12,  2000 (the  "Asset  Purchase
Agreement"),  pursuant  to which  Cytomedix  and its  affiliates  has  agreed to
purchase  certain  of the assets of  Curative  and its  affiliates  as set forth
therein;

                  WHEREAS,  pursuant to Section 2.7(a)(ix) of the Asset Purchase
Agreement, it is a condition to the closing of the transactions described in the
Asset Purchase Agreement that the parties hereto enter into this Agreement;

                                    AGREEMENT

                  NOW,  THEREFORE,  for and in consideration of the premises and
the  mutual  covenants  contained  herein,  and  for  other  good  and  valuable
consideration,  the receipt,  adequacy and legal sufficiency of which are hereby
acknowledged, the parties do hereby agree as follows:

                                   ARTICLE I.
                                    SERVICES

                  During  the  Transitional  Period (as  defined in Section  3.1
below), Cytomedix hereby engages Curative to provide quality assurance services,
warehouse  services,  information  services,  finance  services,  human resource
services,  accounting services, access to e-mail and computers, access to office
space, and such other  transition  assistance as may be agreed upon by Cytomedix
and Curative during the Transitional  Period,  in each case as may be reasonably
directed by Cytomedix from time to time, and,  except as otherwise  specified by
Cytomedix,  in the manner and at a relative level of service,  where applicable,
consistent in all material  respects with that provided by Curative with respect
to the Procuren Operations (as defined in the Asset Purchase Agreement) prior to
the date hereof (all such services, the "Transitional  Services"),  and Curative
hereby accepts such engagement,  all on the terms and conditions  herein. In the
event that Curative  shall be unable to perform any services as required by this
Agreement for any reason, Curative and Cytomedix shall cooperate in obtaining an
alternative means of providing such services.

                                  ARTICLE II.
                                     PAYMENT

                  The  Transitional  Services shall be provided by Curative at a
cost which is equal to the reasonable  direct  expenses  (excluding any overhead
allocation)  incurred by Curative in providing such services,  including but not
limited to any costs in connection with utilizing  consultants (such amount, the
"Service Fees"), plus the Monthly Base Fee (as defined below) (the Services Fees
and Monthly Base Fee together,  the "Fees").  Within thirty (30) days  following
the end of each calendar month,  Curative shall send Cytomedix a monthly invoice
(a)  showing  the amount of the Fees owing by  Cytomedix,  and (b)  providing  a
reasonably  detailed  description of the services  provided by Curative,  during
that month.  The Fees shall be paid by Cytomedix  within thirty (30) days of its
receipt of the invoice  therefor.  If so requested by Cytomedix,  Curative shall
provide a good faith estimate of the  out-of-pocket  costs that Curative expects
to incur in providing  any  requested  service.  The  "Monthly  Fee" shall be an
amount equal to (i) $5,000 per month  during the first and second  months of the
Transition  Period,  (ii) $6,000 per month during the third and fourth months of
the  Transition  Period,  and (iii)  $7,000 per month  during the balance of the
Transition Period (as such period may be extended pursuant to Section 3.4).

                                  ARTICLE III.
                              TERM AND TERMINATION

Section  3.1 Term.  The term of this  Agreement  (such term,  the  "Transitional
Period")  commences  upon the Effective  Date and terminates six (6) months from
the date thereof,  unless earlier terminated  pursuant to (a) the mutual consent
of the parties, or (b) Sections 3.2 or 3.3 below.

Section 3.2  Termination  by Cytomedix.  Cytomedix may terminate  this Agreement
without cause upon thirty (30) days' prior written notice to Curative.

Section 3.3  Termination  by Either Party.  Upon thirty (30) days' prior written
notice to the other party,  either  party may  terminate  this  Agreement if the
other party breaches any of its material obligations hereunder and fails to cure
such breach by the end of such thirty (30) day period.  Section 3.4 Extension by
Cytomedix.  Cytomedix  may  elect  to  extend  the  Transitional  Period  for an
additional  three (3) months  upon thirty  (30) days'  prior  written  notice to
Curative,  provided that in any event the  Transitional  Period shall not exceed
nine (9) months.  Section 3.5 Effect of  Termination.  In the event of notice of
termination,  Curative shall continue to provide the Transitional Services up to
the  date of  termination.  Upon  termination,  Cytomedix  shall  pay the  other
Curative any moneys then due and owing up to the date of  termination,  and each
party cease using and return any Confidential and Proprietary Information except
as otherwise set forth in Section 2.4 of the Supply Agreement.

                                   ARTICLE IV.
                                 CONFIDENTIALITY

                  Each party  acknowledges  that any information  concerning the
other  party  received  in  connection  with  this  Agreement  shall  be  deemed
"Confidential and Proprietary  Information" (provided that information contained
within the Assets (as defined in the Asset  Purchase  Agreement)  transferred to
Cytomedix  shall not be  deemed  Confidential  and  Proprietary  Information  of
Curative).  Each party agrees that it shall not permit the  duplication,  use or
disclosure of any such Confidential and Proprietary Information to any person or
entity  (other than its own  employees or agents who must have such  information
for any proper  purpose),  unless (a)  authorized  in writing  and signed by the
other  party,  (b) such  information  was in the  public  domain  at the time of
receipt, or (c) legally required to disclose such information, provided that the
party availing itself of this exception has promptly notified the other party of
such  required  disclosure  and has  used  commercially  reasonable  efforts  to
lawfully  avoid  or  limit  such   disclosure.   Confidential   and  Proprietary
Information  does not include any information  which, at the time of disclosure,
is generally  known by the public and any competitors of either party through no
breach of the disclosing  party. The provisions of this Article IV shall survive
the expiration or termination of this Agreement.

                                   ARTICLE V.
                           ACCESS; RECORDS AND REPORTS

Section 5.1 Access. Subject to Article IV above, during the Transitional Period,
each party shall  provide the other party and its  personnel  with access to the
equipment,  office and  storage  space and systems of such party  during  normal
business  hours  to the  extent  reasonably  required  in  connection  with  the
provision of the Transition Services;  provided, however, that such access shall
be supervised by the appropriate personnel of such party.

Section 5.2 Records and Reports.  Curative shall keep true and accurate records
and books of account in connection with its obligations hereunder. These records
and books of account shall upon reasonable notice be available during business
hours for inspection by Cytomedix.

                                  ARTICLE VI.
                                 INDEMNIFICATION

Section 6.1  Indemnification  by Curative.  Curative  shall  indemnify  and hold
harmless Cytomedix, its affiliates and agents harmless from all losses, damages,
claims,  penalties  and  expenses,  including,  without  limitation,  reasonable
attorneys' fees, arising out of or in connection with (a) any material breach of

or omissions of Curative, its employees, agents or representatives in connection
with this Agreement.

Section 6.2 Indemnification by Cytomedix. Cytomedix shall indemnify and save and
hold  Curative,  its affiliates  and agents  harmless from all losses,  damages,

                                  ARTICLE VII.

Section 7.4 Waiver. The rights and remedies of the parties to this Agreement are
cumulative and not  alternative.  Neither the failure nor any delay by any party
in exercising any right under this Agreement operates as a waiver of such right,
and no single or  partial  exercise  of any such  right  precludes  any other or
further  exercise  of such  right or the  exercise  of any other  right.  To the
maximum extent permitted by applicable law, (a) no claim or right arising out of
this Agreement can be discharged by one party,  in whole or in part, by a waiver
or  renunciation  of the claim or right  unless in  writing  signed by the other
party;  (b) no waiver that may be given by a party will be applicable  except in
the specific  instance for which it is given;  and (c) no notice to or demand on
one party  will be deemed to be a waiver of any  obligation  of such party or of
the right of the party  giving  such  notice  or demand to take  further  action
without notice or demand as provided in this Agreement.

Section 7.5 Entire  Agreement  and  Modification.  This  Agreement and the Asset
constitute the entire agreement  between the parties with respect to the subject
matter of this Agreement and supersede all prior written and oral agreements and
understandings  between the parties with  respect to the subject  matter of this
Agreement.  This  Agreement  may not be  amended  except by a written  agreement
signed on behalf of each of the parties hereto.

Section 7.6 Assignment. No party to this Agreement may
assign, transfer, or otherwise dispose of any of its rights,
duties, or obligations hereunder without the prior written
consent of the other party hereto; provided, that either party
may assign, transfer, or otherwise dispose of any of its rights,
duties or obligations hereunder to any of its affiliates without
the prior consent of the other party (in which case the assigning
party shall continue to be liable for its obligations hereunder).
Subject to the foregoing, this Agreement shall be binding upon
and shall inure to the benefit of the parties hereto and their
permitted successors and assigns.

Section 7.7 Severability.  If any provision of this Agreement is held invalid or
unenforceable  by any court of competent  jurisdiction,  the other provisions of
this Agreement  remain in full force and effect.  The parties further agree that
if  any  provision   contained  herein  is,  to  any  extent,  held  invalid  or
unenforceable in any respect under the laws governing this Agreement, they shall
take any actions necessary to render the remaining  provisions of this Agreement
valid and enforceable to the fullest extent  permitted by law and, to the extent
necessary,  shall  amend or  otherwise  modify  this  Agreement  to replace  any
provision  contained herein that is held invalid or  unenforceable  with a valid
and enforceable  provision  giving effect to the intent of the parties.

Section 7.8 No Third Party Beneficiary. No provision of this Agreement shall
create, or be deemed to create, any legal or equitable right in any person not a
party to this Agreement or give any such person any claim against any party to
this Agreement that such party would not have but for this Agreement.

Section 7.9 Section Headings; Construction. The headings of
Articles and Sections in this Agreement are provided for
convenience only and will not affect its construction or
interpretation. All words used in this Agreement will be
construed to be of such gender or number as the context requires.
The language used in the Agreement shall be construed, in all
cases, according to its fair meaning, and not for or against any
party hereto. The parties acknowledge that each party has
reviewed this Agreement and that rules of construction to the
effect that any ambiguities are to be resolved against the
drafting party shall not be available in the interpretation of
this Agreement.

Section 7.10 Governing Law; Jurisdiction. This Agreement is to be
governed by and construed under the laws of the State of New York
without regard to conflicts of laws principles that would require the
application of any other law. The parties agree that the state and
federal courts located in New York County, New York shall be the sole
venue and shall have sole jurisdiction for the resolution of all
disputes arising hereunder.

Section  7.11  Execution  of  Agreement,  Counterparts.  This  Agreement  may be
executed  in one or more  counterparts,  each of which  will be  deemed to be an

                            OBLIGATIONS OF CYTOMEDIX

Section  2.1  Supply of  Procuren.  During the Term,  subject  to  Section  2.2,
Cytomedix  shall use its Best Efforts to supply Curative with such quantities of
Procuren  as  to  supply  one  hundred   percent  (100%)  of  Curative's   total
requirements  for Procuren in the  Procuren  States for use in  connection  with
Curative's wound care centers, all on the terms and conditions herein.

Section 2.2       Net Loss Procuren States.

(a) Notwithstanding Section 2.1, Cytomedix shall, subject to Section
2.2(d) below, have no obligation to supply Procuren to Curative
in any Procuren State in which, during any two (2) consecutive
calendar quarters, Cytomedix's Blood Processing Facilities Costs
in connection with the Procuren Operations in such state have
exceeded the revenue received by Cytomedix in connection with the
sale of Procuren to Curative in such state (such difference, the
"Procuren State Deficiency") (any such state, a "Net-Loss
Procuren State").

(b)      Notwithstanding Section 2.1, Cytomedix shall, subject to Section 2.2(e)
 below, have no obligation to supply Procuren to Curative in any or all of the
 Procuren States, in the event that, during any two (2) consecutive calendar
 quarters, the sum of (i) the Blood Processing Facilities Costs in the Procuren
 States, plus the Technical Costs and Expenses, have exceeded (ii) the revenue
 received by Cytomedix in connection with the sale of Procuren to Curative in
 the Procuren States (such difference, the "National Deficiency")
(any state designated by Cytomedix pursuant to the terms of this Section 2.2(b),
 a "Designated Net-Loss Procuren State"); provided,
 however, that Cytomedix may only designate Procuren States as Designated
 Net-Loss Procuren States to the extent that, during the previous two (2)
 calendar quarters, the revenue received by Cytomedix from the sale of Procuren
 in the Procuren States not designated as Designated Net-Loss Procuren States
 does not exceed (a) the Blood Processing Costs and Expenses in the Procuren
 States not designated  as Designated Net-Loss Procuren States, plus (b)
 the Technical Costs and Expenses.

(c) Within  thirty (30) days after the end of each calendar  quarter,  Cytomedix
shall provide  Curative with written  notice of any Procuren State (such notice,
the  "Net-Loss  Notice")  that is a  Net-Loss  Procuren  State  or a  Designated
Net-Loss  Procuren  State  based  upon  the  results  of the  previous  two  (2)
consecutive calendar quarters,  together with written  documentation showing the
basis upon which such determination has been made. At such time, Cytomedix shall
have no further  obligation  to supply  Procuren to  Curative  in such  Net-Loss
Procuren State or Designated Net-Loss Procuren State, as the case may be, except
as set forth in  Sections  2.2(d)  and 2.2(e)  below;  provided,  however,  that
Cytomedix shall be obligated to supply  Procuren  pursuant to any Orders already
submitted by Curative.

(d) Notwithstanding  Section 2.2(a),  Cytomedix shall be
obligated to continue to supply Procuren in any Net-Loss  Procuren State, in the
event that,  within  fifteen  (15) days of  Curative's  receipt of the  Net-Loss
Notice:
          (i)  Curative  pays   Cytomedix  the  amount  of  the  Procuren  State
               Deficiency  with  respect  to  the  two  (2)  previous   calendar
               quarters.  In such event,  Cytomedix shall be obligated to supply
               Procuren to Curative in such Net-Loss  Procuren  State until such
               time, if any,  that Curative  elects not to pay the amount of any
               Procuren  State  Deficiency  with respect to the two (2) previous
               calendar  quarters  (to the extent not  already  paid by Curative
               pursuant to an earlier  Net-Loss Notice) pursuant to a subsequent
               Net-Loss Notice; or

          (ii) Curative notifies  Cytomedix in writing that the exclusive supply
               obligation  set forth in Section  2.3 below will no longer  apply
               with respect to such Net-Loss  Procuren  State and that Cytomedix
               may sell Procuren to any person in such state.


(e) Notwithstanding Section 2.2(b),  Cytomedix shall be obligated to
continue to supply Procuren in any Designated  Net-Loss  Procuren State in the
event that, within fifteen  (15)  days  of  Curative's  receipt  of the
Net-Loss Notice:

     (i) Curative  pays  Cytomedix the amount of the National  Deficiency,  with
respect to the two (2)  previous  calendar  quarters.  In such event,  Cytomedix
shall be obligated to supply  Procuren to Curative in such  Designated  Net-Loss
Procuren  State until such time,  if any,  that  Curative  elects not to pay the
amount of any National  Deficiency with respect to the two (2) previous calendar
quarters  (to the extent not  already  paid by  Curative  pursuant to an earlier
Net-Loss Notice) pursuant to a subsequent Net-Loss Notice; or

     (ii)  Curative  notifies  Cytomedix  in writing that the  exclusive  supply
obligation  set forth in Section 2.3 below will no longer  apply with respect to
such Designated  Net-Loss Procuren State and that Cytomedix may sell Procuren to
any person in such state.

          (f) Nothing contained herein to the contrary,  in the event that there
          are any  consents  to  assignment  with  respect to the real  property
          leases  relating  to the  Facilities  that have not been  obtained  at
          Closing (as defined in the Asset Purchase  Agreement) and the owner of
          the  real  property  has  delivered  a notice  to  vacate  or  similar
          instrument to Cytomedix and Cytomedix has relocated from such Facility
          as the result  thereof,  Cytomedix  shall have no obligation to supply
          Curative with Procuren in such state until such time that Cytomedix is
          able to  relocate  such  Facility  and  resume at a new  Facility  the
          Procuren Operations as were previously conducted.

Section 2.3 Exclusive Supply  Obligation.  During the Term,  Cytomedix shall not
sell or  distribute  Procuren  to any  person in the  United  States  other than
Curative;  provided,  however, that the foregoing restriction shall not apply to
the  distribution of Procuren by Cytomedix to any third party in connection with
any Clinical Trial. Nothing in this Agreement restricts the ability of Cytomedix
to sell or distribute  Procuren in any country other than the United States. The
provisions of this Section 2.3 shall terminate upon FDA approval of Procuren, if
any.

Section 2.4 Protocols. During the Term, Cytomedix shall furnish
Curative with all the necessary protocols and procedures relating to
Procuren at such time as such protocols and procedures become
available.

                                  ARTICLE III.
                                     PAYMENT

Section 3.1 Purchase  Price.  The purchase price for the Procuren (the "Purchase
Price")  to be  supplied  hereunder  shall  be  set at the  sole  discretion  of
Cytomedix  and shall be  payable as set forth in  Section  3.2 below;  provided,
however,  that prior to the receipt of FDA approval of Procuren,  if any, if the
Purchase  Price  exceeds  the  Procuren  Costs,   Cytomedix  shall  rebate  such
difference  to  Curative  either by cash  payment or credit  against the Monthly
Charges as defined in Section 3.2 below.

Section  3.2  Payment.  Cytomedix  shall send  Curative  an invoice on a monthly
basis, in arrears,  for the Procuren supplied to Curative and any other expenses
payable by Curative during the immediately preceding calendar month (such amount
owed by Curative,  the "Monthly  Charges"),  together with a report  showing the
calculation  of the  Monthly  Charges  for such  month.  Curative  shall pay the
Monthly  Charges to  Cytomedix  within  thirty  (30) days of the date of invoice
therefor.  If the Monthly  Charges  remain  unpaid after thirty (30) days of the
date of invoice, interest shall accrue on such unpaid amount at the lower of (a)
fifteen percent (15%) per annum, or (b) the highest rate permitted by law, until
paid.

Section 3.3 Cancellation;  Unsuitability for Use.

                    (a) Except as set forth in Section  3.3(b) or 3.3(c)  below,
               if Curative  cancels any Order for any reason or if any  Procuren
               supplied hereunder is unsuitable for the treatment of patients as
               the result of any action or inaction by Curative,  Curative shall
               reimburse Cytomedix for all indirect and direct costs incurred by
               Cytomedix in connection with the manufacture of such Procuren.

                    (b) If any Procuren supplied hereunder is unsuitable for the
               treatment  of patients as the result of any action or inaction by
               Cytomedix,  Curative shall have no obligation to pay the Purchase
               Price with respect to such Procuren.

                    (c) If any Procuren supplied hereunder is unsuitable for the
               treatment of patients and the parties are unable to determine the
               cause of such  unsuitability,  Curative  shall pay fifty  percent
               (50%) all  indirect  and direct  costs  incurred by  Cytomedix in
               connection with the manufacture of such Procuren.

                    (d) In any such event,  any adjustment to the Purchase Price
               shall be  reflected  in the invoice sent by Cytomedix to Curative
               pursuant to Section 3.2.


Section 3.4 Taxes. In addition to the prices and charges specified
herein, the amount of any present or future sales, use, excise,
personal property, duty, ad valorem or similar tax or assessment
(other than taxes based on Cytomedix's net income) applicable to the
sale of the Procuren hereunder to Curative shall be paid by Curative
when due. If Curative is exempt from sales tax by its status as a
distributor, Curative shall provide evidence of a sales tax exemption
certificate or reseller's registration number.

                                  ARTICLE IV.
                                ORDERS; DELIVERY

Section 4.1 Orders.
Curative shall initiate all orders of Procuren by submitting
a written order (the  "Order") to Cytomedix  for the purchase of Procuren  which
shall  specify or contain  (a) the  quantity of units to be  purchased,  (b) the
scheduled delivery date (which shall in no event be a date earlier than fourteen
(14) days from the date the blood of the patient  necessary for the  manufacture
of Procuren is received by  Cytomedix  or such other time period as set forth in
Exhibit  5.1  hereof),  (c)  the  address  for  shipment,  and  (d)  such  other
information   reasonably  requested  by  Cytomedix,   together  with  sufficient
quantities  of the  blood  of the  patient  necessary  for  the  manufacture  of
Procuren.  In all such  cases,  such  blood  shall be  shipped  by  Curative  to
Cytomedix according to the instructions of Cytomedix.

Section 4.2 Delivery of Procuren.
Within  fourteen  (14) days from the date the
blood of the patient  necessary for the  manufacture  of Procuren is received by
Cytomedix  or such  other  time  period  as set  forth in  Exhibit  5.1  hereof,
Cytomedix  shall  deliver  Procuren to the address  specified in the Order along
with the  Procuren  Release Test  Results,  substantially  in the form  attached
hereto as Exhibit 4.2.  Curative shall be notified of such shipment and shall be
provided with the name of the common  carrier and the package  tracking  number.
Freight charges shall be paid by Cytomedix.  Title and risk of loss with respect
to the  Procuren  supplied  hereunder  shall  pass to  Curative  at the point of
delivery at the address  specified in the Order. In the event Cytomedix fails to
deliver  Procuren  within the time  period set forth  above and the  Procuren is
unsuitable for treatment as the result of such delay or if any Procuren supplied
by Cytomedix is otherwise  unsuitable  for treatment as the result of any action
or inaction by  Cytomedix,  (a)  Curative  shall have no  obligation  to pay the
Purchase  Price in  connection  with the Order of such  Procuren as set forth in
Section 3.3(b),  and (b) if Curative submits another Order for the same patient,
Cytomedix shall promptly redeliver Procuren with respect to such patient for the
Purchase  Price  and on the  other  terms  and  conditions  herein.  Cytomedix's
obligation  to redeliver  Procuren as set forth above shall be  Curative's  sole
remedy in the event any Procuren supplied  hereunder is unsuitable for treatment
as the result of any late  delivery or other  action or  inaction by  Cytomedix.

Section 4.3  Notification.
Each party shall provide the other party with notice
of any adverse  experience  involving  Procuren  resulting in serious  injury or
death as soon as possible but in any event within  twenty-four  (24) hours after
such party receives notice of such  occurrence,  whether in the United States or
any foreign country,  and whether sold by such party or any third party.

Section4.4 Transportation of Blood and Procuren. Curative acknowledges
and agrees that until such time, if any, that Procuren receives FDA
approval (or such earlier time that Cytomedix provides written notice
that the restrictions of this Section 4.4 no longer apply), Curative
shall not transport Procuren across the border of any state for any
reason whatsoever.

Section 4.5 Product Labeling. In order to comply with applicable law
and in order to protect Cytomedix from claims and liabilities,
Curative's communications and representations to customers shall be
true, accurate, complete and consistent with the labeling of Procuren.
Curative shall not modify, repackage, adulterate, misbrand, alter or
add labels to or remove labels from any Procuren without the prior
written approval of Cytomedix.

                         REPRESENTATIONS AND WARRANTIES

Section 5.1  Representations and Warranties of Cytomedix.  Cytomedix  represents
and warrants that the Procuren to be supplied  hereunder will be manufactured in
accordance with the  specifications set forth in Exhibit 5.1 attached hereto, as
it may be amended from time to time.

Section 5.2  Limitation  of Warranty.  EXCEPT AS SET FORTH IN SECTION 5.1 ABOVE,
CYTOMEDIX MAKES NO EXPRESS OR IMPLIED WARRANTIES OR REPRESENTATIONS WITH RESPECT
TO THE PROCUREN TO BE SUPPLIED  HEREUNDER OR OTHERWISE IN  CONNECTION  WITH THIS
AGREEMENT, INCLUDING ANY WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR
PURPOSE OR ANY WARRANTY  RELATING TO THE EFFICACY OF PROCUREN OR ANY WARRANTY OF
NONINFRINGEMENT  OF THE RIGHTS OF ANY THIRD PARTY,  AND ALL SUCH  WARRANTIES ARE
HEREBY EXPRESSLY DISCLAIMED. CYTOMEDIX MAKES NO WARRANTY, EXPRESS OR IMPLIED, TO
ANY  PERSON  OR  ENTITY  OTHER  THAN  CURATIVE  CONCERNING  PROCUREN.   CURATIVE
ACKNOWLEDGES  THAT THIS  LIMITATION  OF  WARRANTY IS A MATERIAL  INDUCEMENT  FOR
CYTOMEDIX TO ENTER INTO THIS AGREEMENT.

Section 5.3       Survival.  The provisions of this Article V shall survive
                  the termination of this Agreement.

                                  ARTICLE VI.
                                 CONFIDENTIALITY

                  Each party  acknowledges  that any information  concerning the
other  party  received  in  connection  with  this  Agreement  shall  be  deemed
"Confidential and Proprietary  Information" (provided that information contained
within the Assets (as defined in the Asset  Purchase  Agreement)  transferred to
Cytomedix  shall not be  deemed  Confidential  and  Proprietary  Information  of
Curative). Except as otherwise set forth herein, each party agrees that it shall
not permit the  duplication,  use or  disclosure  of any such  Confidential  and
Proprietary Information to any person or entity (other than its own employees or
agents  who must have such  information  for any  proper  purpose),  unless  (a)
authorized in writing and signed by the other party, or (b) legally  required to
disclose  such  information,  provided  that the party  availing  itself of this
exception has promptly notified the other party of such required  disclosure and
has used  commercially  reasonable  efforts  to  lawfully  avoid  or limit  such
disclosure.  Confidential  and  Proprietary  Information  does not  include  any
information  which, at the time of disclosure,  is generally known by the public
through no breach of the  disclosing  party.  The  provisions of this Article VI
survive the expiration or termination of this Agreement.

                                  ARTICLE VII.
                                    INSURANCE

                  During  the  Term,  each  party  shall,  at its sole  cost and
expense,  maintain  Comprehensive Public General Liability Insurance,  including
contractual liability,  product liability,  and personal injury coverage, with a
minimum combined single limit of $1,000,000 per occurrence, $3,000,000 per year,
and naming the other party as an  additional  insured.  Each party shall provide
the other party with a Certificate  of Insurance  evidencing  such coverage upon
request  thereof by such  party.  Each party shall give the other party at least
thirty (30) days' prior written notice of the expiration or cancellation  of, or
any material  change in, any insurance  policy required to be maintained by such
party pursuant to the terms of this Agreement.

records referenced above,  including the Patient Data, subject to any applicable
laws.  Cytomedix shall have the right to access and use the Patient Data for any
lawful purpose, including getting data to support any necessary filings with the
FDA, subject to any applicable laws.

     (b) Cytomedix shall be entitled to conduct an audit,  from time to time, of
Curative's  methods and procedures in connection with the blood product supplied
by Curative  for the  manufacture  of Procuren  to assure  compliance  with this
Agreement and product specifications.  Cytomedix may engage an independent third
party auditor to conduct such audits.  Curative  shall  cooperate with Cytomedix
and its  designated  auditor in the  performance  of such  audits and shall take
prompt  and  appropriate  action  to  correct  any  deficiencies  discovered  by
Cytomedix  or its auditor.  Curative  shall be entitled to receive a copy of any
audit reports produced by or on behalf of Cytomedix hereunder.

Section 8.2       Maintenance of Records by Cytomedix; Audits.

(a)               Cytomedix  shall  maintain full and accurate books and records
                  in connection  with the  performance of its duties  hereunder.
                  All such books and records shall be kept and maintained for at
                  least the greater of (a) three (3) years after the termination
                  of this Agreement,  or (b) the minimum amount of time required
                  by law.  Curative  shall  have the right,  during  Cytomedix's
                  business hours upon reasonable  prior notice to Cytomedix,  to
                  inspect any of the books and records referenced above, subject
                  to any applicable laws.

(b) Until such time, if any, that Procuren receives FDA approval, Curative shall
be entitled to conduct an audit,  from time to time, of Cytomedix's  methods and
procedures in connection  with the  manufacture of Procuren  hereunder to assure
compliance with this Agreement and product  specifications.  Curative may engage
an  independent  third party  auditor to conduct  such audits.  Cytomedix  shall
cooperate  with Curative and its designated  auditor in the  performance of such
audits and shall take prompt and appropriate  action to correct any deficiencies
discovered by Curative or its auditor.  Cytomedix shall be entitled to receive a
copy of any  audit  reports  produced  by or on behalf  of  Curative  hereunder.

                                  ARTICLE IX.
                                  IMPROVEMENTS

Section 9.1  Definition.  For the  purposes of this  Article IX,  "Improvements"
shall mean any development, enhancement, or modification in the Procuren product
or its process for manufacturing  that arises on or after the Effective Date and
results from the work of any employee or consultant of Curative.

Section 9.2 Title to  Improvements.  Cytomedix shall have the right, but not the
obligation,  to  take  Curative's  right,  title  and  interest  in  and  to any
Improvements,  whereupon the same, as more specifically set forth in Section 9.3
below,  shall be  incorporated  into the  definition  of  Procuren  patents  and
know-how included within the Assets (as defined in the Asset Purchase Agreement)
transferred  to Cytomedix  under the Asset  Purchase  Agreement.  Curative shall
fully disclose any such  Improvements  to Cytomedix in writing within sixty (60)
days after their actual or constructive reduction to practice. The writing shall
include, if appropriate and without limitation, any drawings,  laboratory notes,
methods,   processes,   samples,   materials  and  specification  in  Curative's
possession or control.  Curative shall promptly  respond and assist Cytomedix or
any of its  attorneys  responsible  for  evaluating  the  patentability  of such
Improvements  and shall make  available,  at no cost to Curative,  knowledgeable
persons,  including without limitation,  the inventor, to consult with Cytomedix
regarding the nature and details of all Improvements.

Section 9.3  Notification  by Cytomedix.  Cytomedix  shall,  upon receipt of any
written notice from Curative  pursuant to Section 9.2, notify  Curative  whether
Cytomedix  desires to take Curative's  right,  title and interest in and to such
Improvements.  If so, any such Improvements that constitute, in Cytomedix's sole
discretion,  patentable  inventions  shall  thereupon be  incorporated  into the
definition  of  Procuren  patents  included  within  the Assets  transferred  to
Cytomedix under the Asset Purchase  Agreement,  provided that Cytomedix,  within
one (1) year or such longer period consented to by Curative (which consent shall
not be  unreasonably  withheld),  files an application  for one (1) or more U.S.
and/or foreign  patents and thereafter in good faith  prosecutes  and, if one or
more  patents  are  issued,  maintains,  patent  protection  in  respect to such
Improvements.  Any  Improvements  that do not, in Cytomedix's  sole  discretion,
constitute  patentable  inventions shall be incorporated  into the definition of
know-how  included  within the Assets  transferred to Cytomedix  under the Asset
Purchase Agreement. Curative shall execute any necessary documents and cooperate
in good faith to the extent that  Cytomedix may  reasonably  require in order to
enable Cytomedix to fully enforce and exercise its rights to such  Improvements.
During the time  allowed for filing an  application  for a U.S.  and/or  foreign
patent  with  respect  to any  Improvements,  Curative  shall  refrain  from any
activity, including without limitation, the sale, offer for sale, public use, or
disclosure of said  Improvements,  that could  foreseeably  cause  forfeiture of
patent rights therein.

                                   ARTICLE X.
                             LIMITATION OF LIABILITY

Section 10.1  Limitation on Types of Damages.  NOTWITHSTANDING  ANY PROVISION OF
THIS AGREEMENT TO THE CONTRARY, NEITHER PARTY SHALL BE LIABLE TO THE OTHER PARTY
FOR ANY  SPECIAL,  INCIDENTAL,  INDIRECT,  PUNITIVE  OR  CONSEQUENTIAL  DAMAGES,
WHETHER  FORESEEABLE OR NOT,  ARISING OUT OF, OR IN CONNECTION WITH SUCH PARTY'S
FAILURE  TO  PERFORM  ITS  RESPECTIVE  OBLIGATIONS  OR BREACH OF ITS  RESPECTIVE
REPRESENTATIONS HEREUNDER.

Section 10.2      Limitation on Amount of Damages.  IN NO EVENT SHALL CYTOMEDIX
BE LIABLE TO CURATIVE  IN CONNECTION WITH THIS AGREEMENT IN AN AGGREGATE AMOUNT
THAT EXCEEDS THE TOTAL AMOUNT PAID BY CURATIVE TO CYTOMEDIX
PURSUANT TO THE TERMS HEREIN.
Section 10.3      Survival.  The provisions of this Article X survive the
expiration or termination of this Agreement.

                                  ARTICLE XI.
                                 INDEMNIFICATION

Section 11.1  Indemnification by Curative.  Subject to Article X, Curative shall
fully  defend  and hold  Cytomedix  and its  Affiliates,  and  their  respective
directors,  stockholders,  employees,  officers and agents harmless from any and
all  claims,  demands,  damages,  liabilities,   costs  or  expenses  (including
attorneys'  fees and  expenses)  arising  out of or in  connection  with (a) the
negligent,  reckless or intentional acts or omissions of Curative or its agents,
or (b) the breach by  Curative  of any  representation,  warranty,  covenant  or
obligation in this Agreement.

Section 11.2 Indemnification by Cytomedix. Subject to Article X, Cytomedix shall
fully  defend  and  hold  Curative  and its  Affiliates,  and  their  respective
directors,  stockholders,  employees,  officers and agents harmless from any and
all  claims,  demands,  damages,  liabilities,   costs  or  expenses  (including
attorneys'  fees and  expenses)  arising  out of or in  connection  with (a) the
negligent, reckless or intentional acts or omissions of Cytomedix or its agents,
or (b) the breach by  Cytomedix  of any  representation,  warranty,  covenant or
obligation in this Agreement.

Section 11.3      Procedure for Indemnification - Third Party Claims.

(a)               Promptly after receipt by an  indemnified  party under Section
                  11.1 or 11.2 of notice of the  commencement  of any proceeding
                  ("Proceeding")  against it by a third party,  such indemnified
                  party shall,  if a claim is to be made against an indemnifying
                  party under such  Sections,  give  notice to the  indemnifying
                  party of the commencement of such Proceeding,  but the failure
                  to  notify  the  indemnifying   party  does  not  relieve  the
                  indemnifying  party of any  liability  that it may have to any
                  indemnified party,  except to the extent that the indemnifying
                  party   demonstrates  that  the  defense  of  such  action  is
                  prejudiced  by the  indemnified  party's  failure to give such
                  notice.

     (b)  If an indemnified party gives notice to the indemnifying  party of the
          commencement  of a  Proceeding  referred  to in Section  11.3(a),  the
          indemnifying  party is entitled to participate in such Proceeding and,
          to the extent that it wishes to assume the defense of such  Proceeding
          with counsel  satisfactory to the indemnified  party and, after notice
          from the indemnifying  party to the indemnified  party of its election
          to assume the defense of such Proceeding,  the  indemnifying  party is
          not, as long as it diligently  conducts  such  defense,  liable to the
          indemnified  party under this Article XI for any fees of other counsel
          or any other expenses with respect to the defense of such  Proceeding,
          in  each  case  subsequently  incurred  by the  indemnified  party  in
          connection with the defense of such Proceeding,  other than reasonable
          costs of investigation  (unless (i) the  indemnifying  party is also a
          party to such Proceeding and the indemnified  party determines in good
          faith that joint  representation  would be inappropriate,  or (ii) the
          indemnifying  party  fails  to  provide  reasonable  assurance  to the
          indemnified party of its financial  capacity to defend such Proceeding
          and provide  indemnification with respect to such Proceeding).  If the
          indemnifying party assumes the defense of a Proceeding, (x) it will be
          conclusively  established  for  purposes  of this  Agreement  that the
          claims made in that  Proceeding are within the scope of and subject to
          indemnification; (y) no compromise or settlement of such claims may be
          effected by the  indemnifying  party without the  indemnified  party's
          consent  unless (A) there is no finding or admission of any  violation
          of legal requirements or any violation of the rights of any person and
          no effect on any other claims that may be made against the indemnified
          party,  and (B) the sole relief provided is monetary  damages that are
          paid in full by the indemnifying  party; and (z) the indemnified party
          will have no liability with respect to any compromise or settlement of
          such claims  effected  without its  consent.  If notice is given to an
          indemnifying  party  of the  commencement  of any  Proceeding  and the
          indemnifying   party  does  not,   within  ten  (10)  days  after  the
          indemnified  party's notice is given,  give notice to the  indemnified
          party of its  election to assume the defense of such  Proceeding,  the
          indemnifying  party  will be bound by any  determination  made in such
          Proceeding or any compromise or settlement effected by the indemnified
          party.
(c)  Notwithstanding  the foregoing,  if an indemnified party determines in good
faith that there is a reasonable  probability  that a Proceeding  may  adversely
affect  it other  than as a result  of  monetary  damages  for which it would be
entitled to indemnification under this Agreement,  the indemnified party may, by
notice  to the  indemnifying  party,  assume  the  exclusive  right  to  defend,
compromise,  or settle such Proceeding,  but the indemnifying  party will not be
bound by any  determination of a Proceeding so defended for the purposes of this
Agreement or any  compromise or settlement  effected  without its consent (which
may not be unreasonably withheld).  Section 11.4 Procedure For Indemnification -
Other  Claims.  A claim for  indemnification  for any  matter  not  involving  a
third-party   claim  may  be   asserted   by  notice  to  the  party  from  whom
indemnification is sought.

Section 11.5      Survival.  The provisions of this Article XI survive the
                  expiration or termination of this Agreement.

                                  ARTICLE XII.
                              TERM AND TERMINATION

Section 12.1 Term. Unless earlier  terminated  pursuant to Sections 12.2 or 12.3
below,  this Agreement  commences  upon the Effective  Date and terminates  upon
Cytomedix's  written notice to Curative of the occurrence of a Triggering  Event
(such  period,  the "Term").  For purposes of this Section  12.1, a  "Triggering
Event"  constitutes any reasonable  determination by Cytomedix that FDA approval
of Procuren is not likely to be obtained.  Notwithstanding  the foregoing,  upon
the receipt of FDA approval of  Procuren,  if any, the Term extends for a period
of one (1) year from the date of FDA approval and thereafter may be extended for
successive  terms of one (1) year each upon the mutual  consent  of the  parties
hereto.

Section 12.2   Termination by Cytomedix. Cytomedix may terminate this Agreement:

(a)               If Curative  fails to pay any amounts owed  hereunder when due
                  and does not cure such  non-payment  within  thirty  (30) days
                  thereof; or

(b)               Upon thirty (30) days' prior  written  notice to Curative,  if
                  Curative  breaches  any  of  its  other  material  obligations
                  hereunder  and  fails to cure  such  breach by the end of such
                  thirty (30) day period.

Section 12.3 Termination by Curative. Curative may terminate this Agreement upon
thirty (30) days' prior written notice to Cytomedix,  if Cytomedix  breaches any
of its other material obligations hereunder and fails to cure such breach by the
end of such thirty (30) day period.  In addition,  Curative may  terminate  this
Agreement  for any  reason  upon  ninety  (90)  days'  prior  written  notice to
Cytomedix.

Section 12.4 Termination or Modification in the Event of Governmental Action. If
the parties receive notice of any Governmental Action, the parties shall attempt
in good faith to amend this  Agreement in order to comply with the  Governmental
Action. If the parties,  acting in good faith, are unable to agree to amendments
necessary to comply with the Governmental  Action or if the parties determine in
good  faith  that  compliance  with the  Governmental  Action is  impossible  or
unfeasible,  this  Agreement  shall  terminate at the end of ten (10) days after
written notice thereof by either party. Neither party shall be in breach of this
Agreement or liable to the other party as the result of the  termination of this
Agreement  pursuant to this Section 12.4. In addition,  nothing contained herein
to the  contrary,  Cytomedix  shall have no  obligation  to supply  Procuren  to
Curative in, and this Agreement shall  otherwise  terminate with respect to, any
Procuren  State in which  (a)  Cytomedix  determines  in good  faith  that it is
impossible or unfeasible to supply Procuren to Curative  hereunder as the result
of any Governmental Action or (b) Cytomedix  otherwise  determines in good faith
that the continued  operation of the Procuren Operations therein would result in
Cytomedix  being in violation of any applicable law,  regulation,  rule or other
legal requirement  applicable to it. Cytomedix shall promptly notify Curative of
such  determination  with respect to any Procuren  State.

Section 12.5 Remedies upon Termination. Termination of this Agreement
shall not limit either party from pursuing any other remedies
otherwise available to it, including, without limitation, injunctive
relief.

Section 12.6 Effect of Termination. In the event
of notice of  termination,  each party shall continue to perform its obligations
hereunder up to the date of termination.  Upon termination,  except as otherwise
provided herein, the obligations of the parties hereunder shall cease; provided,
however,  that Cytomedix shall be obligated to supply  Procuren  pursuant to any
Orders  received  by  Cytomedix  prior  to the  date of  termination.  Following
termination of this  Agreement,  Curative shall promptly pay Cytomedix any money
then due and owing upon receipt of invoice therefor.

                                 ARTICLE XIII.
                                  MISCELLANEOUS

Section 13.1 Force  Majeure.  Neither party shall be in default by reason of any
failure in  performance  of this  Agreement if such failure arises out of causes
beyond the control of such nonperforming  party,  including,  but not restricted
to, acts of God, acts of government,  insurrections,  fires, floods,  accidents,
epidemics, quarantines,  restrictions,  strikes, freight embargoes, inability to
secure  materials  or  transportation  facilities,  or any and all other  causes
beyond the party's reasonable control.

Section 13.2 No Joint  Venture.  Nothing  herein  shall create any  association,
partnership,  joint venture or agency relationship between the parties hereto or
any third party.

Section 13.3 Further  Assurances.  The parties shall  cooperate  reasonably with
each other in  connection  with any steps  required to be taken as part of their
respective  obligations  under  this  Agreement,  and the  parties  agree (a) to
furnish upon request to each other such further information,  (b) to execute and
deliver to each other  such other  documents,  and (c) to do such other acts and
things,  all as the other  party  may  reasonably  request  for the  purpose  of
carrying out the intent of this Agreement.

Section 13.4      Compliance with Legal Requirements.

(a)               Curative  covenants  that  it  shall  comply  in all  material
                  respects with all Federal,  state or local laws,  regulations,
                  ordinances or other legal  requirements in connection with the
                  transportation,  storage, use, resale and disposal of Procuren
                  and the performance of its duties hereunder.

(b) Cytomedix  covenants that it shall comply in all material  respects with all
Federal,   state  or  local  laws,   regulations,   ordinances  or  other  legal
requirements  in connection with the storage and manufacture of Procuren and the
performance  of  its  duties  hereunder.

Section  13.5  Notices.  All  notices,consents,  waivers,  and other
communications  under this  Agreement must be in writing and are deemed to have
been duly given when (a)  delivered  by hand with
written  confirmation  of receipt,  (b) sent by facsimile with  confirmation  of
transmission by the transmitting equipment, (c) five (5) days after delivery, if

Section  13.6
Waiver.  The rights and remedies of the parties to this  Agreement
are  cumulative  and not  alternative.  Neither the failure nor any delay by any
party in exercising any right under this Agreement  operates as a waiver of such
right,  and no single or partial  exercise of any such right precludes any other
or further  exercise of such right or the  exercise of any other  right.  To the
maximum extent permitted by applicable law, (a) no claim or right arising out of
this Agreement can be discharged by one party,  in whole or in part, by a waiver
or  renunciation  of the claim or right  unless in  writing  signed by the other
party;  (b) no waiver that may be given by a party will be applicable  except in
the specific  instance for which it is given;  and (c) no notice to or demand on
one party  will be deemed to be a waiver of any  obligation  of such party or of
the right of the party  giving  such  notice  or demand to take  further  action
without notice or demand as provided in this Agreement.

Section 13.7
Entire  Agreement and  Modification.  This  Agreement and the Asset
Purchase  Agreement  constitute  the entire  agreement  between the parties with
respect to the subject  matter of this Agreement and supersede all prior written
and oral agreements and  understandings  between the parties with respect to the
subject matter of this Agreement.  This Agreement may not be amended except by a
written  agreement signed on behalf of each of the parties hereto.

Section 13.8
Assignment.  No party to this  Agreement  may  assign,  transfer,  or  otherwise
dispose of any of its rights, duties, or obligations hereunder without the prior
written consent of the other party hereto;  provided,  however,  that (a) either
party may assign, transfer, or otherwise dispose of any of its rights, duties or
obligations  hereunder to any of its Affiliates without the prior consent of the
other  party,  and  (b)  Cytomedix  may  subcontract  any of  its  manufacturing
obligations  hereunder  (provided  that  in  any  such  case  the  assigning  or
subcontracting party shall continue to be liable for its obligations hereunder),
provided that no such  assignment  or delegation  pursuant to clauses (a) or (b)
shall relieve either party from any of its obligations hereunder. Subject to the
foregoing,  this Agreement  shall be binding upon and shall inure to the benefit
of the parties hereto and their permitted  successors and assigns.

Section 13.9
Severability.   If  any   provision  of  this   Agreement  is  held  invalid  or
unenforceable  by any court of competent  jurisdiction,  the other provisions of
this Agreement  remain in full force and effect.  The parties further agree that
if  any  provision   contained  herein  is,  to  any  extent,  held  invalid  or
unenforceable in any respect under the laws governing this Agreement, they shall
take any actions necessary to render the remaining  provisions of this Agreement
valid and enforceable to the fullest extent  permitted by law and, to the extent

Guarantor's  payment in full of any deficiency  under the Obligations  after any
exercise  of  Beneficiary's  rights as to the  Collateral  in  Article VI of the
Royalty Agreement where Beneficiary disposes of the Collateral in a commercially
reasonable manner.

5.       Waivers and Remedies.

5.1 Waivers.  Except as provided in this Agreement,  Guarantor hereby waives (a)

Beneficiary  by reason of this  Agreement are separate and  cumulative and it is
agreed that no one of such  remedies,  whether or not exercised by  Beneficiary,
shall be deemed to be in  exclusion  of any of the other  remedies  available to
Beneficiary  and no one of such remedies shall in any way limit or prejudice any
other legal or equitable  remedy which  Beneficiary  may have hereunder and with
respect  to Section  2.  Except as  provided  in this  Agreement,  mere delay or
failure to act shall not preclude the exercise or  enforcement of any rights and
remedies available to Beneficiary.

5.3 Costs and Expenses.  Guarantor shall pay or reimburse  Beneficiary on demand
for  all  reasonable  out-of-pocket  expenses  (including  reasonable  fees  and
expenses of counsel)  incurred by  Beneficiary  arising out of or in  connection
with any  failure of  Guarantor  to fully and  timely  perform  its  obligations
hereunder.

6.       Representations and Warranties.

6.1 Organization  and Good Standing.  Guarantor is a corporation duly organized,
validly existing, and in good standing under the laws of its jurisdiction,  with

indirectly  (with or without  notice or lapse of time),  breach any provision of
its organizational documents or any resolution adopted by its board of directors

breach of any of the terms or requirements of, or give any Governmental Body the
right to revoke, withdraw,  suspend, cancel, terminate, or adversely modify, any
Governmental Authority.

and will not exceed its debts (including any legal liability, whether matured or
unmatured,  liquidated or unliquidated,  absolute, fixed or contingent, disputed

                                     FORM OF
                          OPINION OF COUNSEL TO SELLER

         1. Curative Health Services is a corporation duly organized,  and based
solely upon a certificate from the Secretary of State of the State of Minnesota,
validly  existing and in good standing under the laws of the state of Minnesota,
with  corporate  power and  authority to execute and deliver the  Agreement  and
consummate the Contemplated Transactions.

         2. CHS Services is a corporation duly organized,  and based solely upon
a  certificate  from the  Secretary of State of the State of  Delaware,  validly
existing  and in good  standing  under the laws of the state of  Delaware,  with
corporate  power  and  authority  to  execute  and  deliver  the  Agreement  and
consummate the Contemplated Transactions.

         3.  The  Agreement  and  Seller's  Closing  Documents  have  been  duly
authorized,  executed and delivered by Seller and  constitute  valid and binding
obligations  of Seller,  enforceable  against  Seller in  accordance  with their
respective terms,  subject to bankruptcy,  reorganization,  insolvency and other
similar laws affecting the  enforcement  of creditors'  rights in general and to
general  principles of equity  (regardless of whether considered in a proceeding
in equity or an action of law).

         4. Neither the  execution  and delivery of the  Agreement  and Seller's
Closing  Documents  nor  the  consummation  of any  or  all of the  Contemplated
Transactions  (i) violates any provision of the Certificate of  Incorporation or
Bylaws (or other governing instrument) of Seller, (ii) breaches or constitutes a
default  (or an  event  that,  with  notice  or  lapse  of time or  both,  would
constitute a default)  under,  or results in the  termination of, or accelerates
the performance required by, or excuses performance by, any Person of any of its
obligations  under,  or causes the  acceleration  of the maturity or any debt or
obligation  pursuant  to,  or  results  in the  creation  or  imposition  of any
Encumbrance  upon the Assets under,  any  agreement or commitment  identified on
Schedule 3.6(b),  Schedule  3.17(a),  or Schedule  3.20(b) of the Agreement,  or
(iii) to the knowledge of such counsel,  violates any statute,  law, regulation,
or rule, or any judgment,  decree,  or order of any court or other  Governmental
Body applicable to Seller.

         5. Except as disclosed on Schedule 3.2(c) of the Agreement, no consent,
approval, or authorization of, or declaration, filing, or registration with, any
Governmental  Body is required by Seller in  connection  with the  execution and
delivery of the Agreement and Seller's Closing  Documents or the consummation of
the Contemplated Transactions.

         6.  The  instruments  of  conveyance,  transfer  and  assignment  to be
delivered by Seller to Buyer at Closing are in form legally sufficient to convey
to Buyer all right,  title and interest of Seller in and to the Assets,  subject
to bankruptcy,  reorganization,  insolvency and other similar laws affecting the
enforcement of creditors' rights in general and to general  principles of equity
(regardless  of whether  considered  in a  proceeding  in equity or an action of
law).  Such  instruments  are in form sufficient for recordation or filing where
such is necessary in order to effect such conveyance, transfer and assignment as
against third parties.

         7. Except as set forth in  Schedule  3.15(a) to the  Agreement,  to the
knowledge  of such  counsel,  there is no  Proceeding  by or before any court or
Governmental Body pending or overtly  threatened in writing against or involving
Seller  that would  adversely  affect any action  taken or to be taken by Seller
pursuant to the Agreement or Seller's  Closing  Documents or in connection  with
the Contemplated Transactions.
