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

(a)  Rolling Forecasts.  Each calendar quarter during the Term, AASTROM shall
     -----------------                                                       
provide MSP with a rolling forecast of the anticipated quantity of each model of
Cell Cassettes AASTROM intends to purchase from MSP during each quarter of the
following twelve-month period. The quantities given for the first three months
of each twelve-month rolling forecast shall be firm orders for the immediately
succeeding quarter (i.e., a three-month forecast given on January 1st would be
deemed firm for the period April 1 - June 30) and AASTROM shall issue its
purchase order therefor and note on such purchase order the number of units it
will require for lot testing in accordance with Section 3(g), the method of
shipment and AASTROM destination for delivery, the scheduled delivery date and
the required documentation to be included with the Shipment Lot. MSP shall have
no obligation to purchase materials or supplies without a purchase order from
AASTROM except as is necessary to meet AASTROM's forecasted requirements.
AASTROM shall pay MSP for labor,

                                      -4-
<PAGE>
 
materials, supplies and direct costs (as set forth in Appendix III) expended by
MSP to fill purchase orders by AASTROM for Cell Cassettes in the event that they
are not used to fulfill such purchase orders. Quantities forecasted beyond the
three-month firm-order period are for planning purposes only.

(b)  No Limit on Sales.  MSP has no right to limit its sales of Cell Cassettes
     -----------------                                                        
or Components to AASTROM to a maximum number of units for any period
notwithstanding that AASTROM's Requirements may constitute less than 100% of
AASTROM's total requirements; provided that, the volume of Cell Cassettes and
                              -------- ----
Components ordered is reasonable in the light of forecasted amounts and previous
delivery schedules. MSP shall have adequate capacity to meet AASTROM's then-
current total firm-order requirements as forecasted pursuant to Section 3(a),
above. MSP will take all steps to put in place additional adequate capacity, if
needed, to meet AASTROM's future requirements as forecasted by AASTROM in
accordance with Section 3(a), above; provided that, the Parties shall cooperate
                                     -------- ---- 
to afford a reasonable transition to the availability of such additional
capacity.

(c)  No Liens.  Except with respect to MSP's purchase money security interest in
     --------                                                                   
Cell Cassettes granted pursuant to Section 5(d), below, MSP will deliver Cell
Cassettes to AASTROM free and clear of all liens, claims and encumbrances.

     --------                                                                
any certifications, manufacturing records and test reports as are required for
AASTROM to accept or reject Cell Cassettes under this Section 3, pursuant to
delivery schedules in AASTROM's purchase orders; provided, that, such schedules
are reasonable in light of forecasted amounts and previous delivery schedules.
Delivery schedules in AASTROM's purchase orders shall not be less than fifteen
(15) days after the date of submission by AASTROM of the purchase order without
MSP's consent. In the event that AASTROM submits a purchase order in excess of
its forecasted requirements for said quarter, MSP agrees to employ good faith
efforts to supply such larger quantity of Cell Cassettes within such a
reasonable period of time as the Parties shall mutually agree. MSP shall not
deliver Cell Cassettes more than ten (10) days prior to scheduled delivery dates
without AASTROM's prior consent. MSP shall not be responsible for failure to
meet agreed-upon delivery dates if due to reasons of force majeure as set forth
in Section 20, below. In the event of partial failure to deliver, MSP will have
the right to receive payment pro rata for Cell Cassettes in fact delivered and
                             --- ----
not rejected by AASTROM under Section 3(f), below.

(e)  Shipment.  Shipment shall be made by MSP to AASTROM's designated U.S.
     --------                                                             
locations, in accordance with AASTROM's purchase orders, F.O.B. destination.
Risk of loss or damage in transit shall remain with MSP until delivered to the
destination specified by AASTROM. AASTROM shall notify MSP within five (5)
business days after receipt if there are any shortages or evidence of damage in
transit and will cooperate with MSP in any claim for loss or damage in transit
that MSP makes against a carrier. The method and route of shipment are at
AASTROM's discretion as set forth in its purchase order. MSP will prepay all
costs, insurance premiums, freight and other expenses incurred in shipment until
delivered to the destination specified by AASTROM and such shipping costs shall
be reimbursed by AASTROM at MSP's cost without mark-up. If AASTROM defaults in
payment for Cell

                                      -5-
<PAGE>
 
Cassettes, MSP may suspend further shipments; however, continuation of shipments
does not constitute a waiver of such default.

(f)  Acceptance Procedures.  Delivery of each Cell Cassette unit shall be deemed
     ---------------------                                                      
accepted by AASTROM unless MSP is notified in writing of AASTROM's rejection of
such delivery within forty-five (45) days after the delivery date (the
"Acceptance Period") due to non-conformance with the Specifications. In such
case, AASTROM shall provide MSP with a written notice of rejection setting forth
in detail the reason for rejection and return the rejected Shipment Lot, or
portion thereof, to MSP at MSP's expense for repair or replacement. Upon receipt
of AASTROM's notice of rejection and return of such Shipment Lot of part
thereof, MSP shall (i) within ten (10) business days thereafter, provide AASTROM
with a root-cause analysis and suggested corrective/preventative actions; and
(ii) diligently replace the nonconforming Shipment Lot or part thereof by
delivery of nondefective conforming units within a reasonable time (not to
exceed thirty (30) calendar days after notification) and endeavor to resolve the
issues related to the rejection. MSP shall credit against the purchase price of
Cell Cassettes, AASTROM's out of pocket costs of testing, including, without
limitation, destructive testing of failed Shipment Lots. AASTROM shall invoice
MSP for such costs, which shall be subject to reasonable audit by MSP or its
representative. MSP reserves the right, at MSP's expense, to have one or more
representatives present at any inspection conducted by AASTROM and to verify the
results of any such inspection and rejection of Shipment Lots. MSP shall have
the right to use conforming units or parts therefrom as replacement units
provided that such units or parts therefrom are in conformance with
Specifications. In the event MSP cannot resolve all nonconformities and deliver
conforming replacement Cell Cassettes as required herein MSP shall issue to
AASTROM a credit for the price of each unit rejected and AASTROM may pursue its
remedies pursuant to this Agreement, including but not limited to Section 17,
below. AASTROM shall pay for repair or replacement for defective Cell Cassettes
(or shall not receive a credit therefor) only to the extent that rejection is
due to a defective component supplied directly by AASTROM. In the event that
MSP's delivery of Cell Cassettes fails to conform to the quantity specified in
AASTROM's purchase order, AASTROM may, but shall not be obligated to, accept
such partial shipment and MSP shall deliver any shortfall in delivery quantity
within five (5) calendar days. Notwithstanding the foregoing, AASTROM agrees to
accept partial shipments from MSP provided that the quantity delivered is at
least ninety percent (90%) of the quantity specified in AASTROM's purchase
order, but only if AASTROM may readily use such partial shipment for its
intended purposes, and AASTROM also agrees to use commercially reasonable
efforts to accept partial shipments of quantities of less than ninety percent
(90%) of the quantity specified in AASTROM's purchase order, but only if AASTROM
may readily use such partial shipment for its intended purpose(s). Any
acceptance of partial shipments by AASTROM shall not be deemed to waive
AASTROM's remedies under Section 17(d) and AASTROM shall be entitled to a
payment credit reflecting the extent of such unit shortfall under a partial
shipment. In the event MSP fails to deliver any shortfall in quantity within
such five (5) day period, AASTROM may pursue its remedies pursuant to this
Agreement.

(g)  Lot Testing.  During the Acceptance Period, AASTROM shall have the right,
     -----------                                                              
but not the obligation, to conduct lot testing on a statistically significant
number of units from each

                                      -6-
<PAGE>
 
Shipment Lot. At the time of submission of AASTROM's purchase orders in
accordance with Section 3(a), AASTROM shall note on such purchase order the
number of units it requires for lot testing. Notwithstanding Section 4(a), MSP
agrees to provide such testing units to AASTROM at MSP's cost to manufacture
such units (without mark-up) provided that the number of units requested is
reasonable given the number of units ordered, and provided further that any
units provided by MSP for lot testing shall not be resold by AASTROM. Any lot
testing conducted by AASTROM pursuant to this section shall not be deemed to
relieve MSP of any of its warranties or obligations hereunder.

SECTION 4.  PRICES.
            ------ 

(a)  Cell Cassette Prices.  Prices for Cell Cassettes purchased during Phase I

and Phase II shall be determined as shown in Appendix III, hereto. Prices are
exclusive of all taxes of any nature imposed by any governmental authority,
except taxes imposed on the income or profits of MSP. All such taxes shall be
for AASTROM's account, whether or not collected, advanced or paid by MSP, and
shall be paid by AASTROM, without mark-up, upon MSP's invoice, unless AASTROM
timely provides proper tax exemption documents.

(b)  Phase I Collaboration Charge.  In addition to being paid for Cell Cassettes
     ----------------------------                                               
ordered by AASTROM during Phase I, AASTROM shall compensate MSP for MSP's
assistance and collaboration, as described in Section 9, below, on the basis set
forth in Appendix III. MSP shall prepare and submit to AASTROM a budget of Phase
I assistance and collaboration costs and expenses for AASTROM's approval. Once
approved, AASTROM may issue purchase orders authorizing the commencement of
collaborative work by MSP. MSP shall submit to AASTROM a monthly invoice
referencing AASTROM's purchase order for assistance and collaboration, together
with such supporting details as AASTROM may reasonably request. Assistance and
collaboration costs shall not exceed the budget approved by AASTROM without
AASTROM's prior written consent. The Parties acknowledge that budgets may need
to be revised to reflect updated cost estimates; however, any changes to
approved budgets will require the Parties' prior written consent.

(c)  Component Order and Prices.  From time to time throughout the Term, AASTROM
     --------------------------

III, together with such supporting documents as AASTROM may reasonably request.
Accounts unpaid beyond their due date will bear interest at a rate, to be
determined by MSP in its sole, absolute discretion, not to exceed the higher of
1 1/2% per month on the unpaid balance or the highest rate legally permissible
in the state of Michigan. If payment by AASTROM is improperly withheld and MSP
retains an agency and/or attorneys to collect amounts overdue, all collection
costs, including without limitation, reasonable attorneys' fees, shall be
payable by AASTROM.

(b)  Deductions from Invoice.  AASTROM will promptly notify MSP of any disputed
     -----------------------                                                   
invoice. It is the intention of the Parties that disputed invoices will be
settled by the Parties in good faith negotiations prior to the invoice due date.
However, unless MSP issues a credit memo, or unless AASTROM rightfully rejects
Cell Cassettes or notifies MSP of its acceptance of a partial shipment pursuant
to Section 3(f), AASTROM shall make full payment of MSP invoices for accepted
Cell Cassettes without deduction and regardless of any claim, counterclaim or
setoff AASTROM may have against MSP, except as such setoff may otherwise be
permitted under Appendix III, Section 3(f) or Section 12(d). Any such claim,
counterclaim or setoff shall be resolved exclusively as a separate matter
pursuant to Section 24, below.

SECTION 11.  RIGHT OF INSPECTION.
             ------------------- 

(a)  Rights of Inspection.  In addition to AASTROM's right to inspect Cell
     --------------------                                                 
Cassettes upon delivery pursuant to Section 3, AASTROM shall have the following
rights of inspection, each such right to be exercised, if at all, at its own
cost and expense:

     (1) to inspect, sample and test Cell Cassette work-in-progress and review
process control reports and manufacturing records at MSP's facilities upon at
least three (3) work days' prior notice to MSP and shall consult with MSP if it
believes that its inspection shows MSP is failing to meet its obligations under
this Agreement (in such event the parties will work together toward resolution
of any such failure); and

     (2) to inspect, sample and test Cell Cassettes at MSP's facilities after
notice by MSP that a Shipment Lot is ready for shipment to a sterilizer
location.  Such inspection must be conducted, if at all, within ten (10) days
after receipt of such notice.

(b)  Waiver.  AASTROM's right to inspect under this Section 11 and any
     ------                                                           
inspection by AASTROM hereunder, or AASTROM's acceptance of or payment for Cell
Cassettes, shall not be deemed to relieve MSP of any of its obligations under
the terms of this Agreement nor a waiver by AASTROM of its rights to inspect
upon delivery pursuant to Section 3 or with respect to breach of warranty as set
forth in Section 12, below.

(c)  Self-Certification.  The Parties shall work together toward self-
     ------------------                                              
certification pursuant to which MSP will conduct in-process controls and
finished device testing in order to augment, and reduce the need for, exercise
by AASTROM of its inspection rights.

(d)  Records; Inspection.  For at least two years after the expiration or any
     -------------------                                                     
earlier termination of this Agreement (under Section 17 below), MSP shall retain
accurate and complete records with respect to its work and manufacture of the
Cell Cassettes to the extent necessary to reasonably satisfy all applicable FDA
and EC requirements and to verify the time worked and material and other costs
invoiced to AASTROM. MSP shall make available to AASTROM, cost information that
AASTROM may reasonably request in connection with the establishment of Phase II
pricing in accordance with Appendix III. Upon reasonable notice to MSP, AASTROM
and/or its designated independent auditor may inspect and conduct a reasonable
audit on such records. If MSP does not agree with the results of the audit, then
the dispute shall be resolved pursuant to Section 24, below. Furthermore, if the
results of such audit indicate an overcharge by MSP of ten percent (10%) or more
of AASTROM's applicable purchase price from MSP, MSP shall reimburse AASTROM for
the cost of performing such audit, otherwise the cost of such audit shall be
borne by AASTROM. If such audit shows an overcharge by MSP of AASTROM's
applicable purchase price from MSP, MSP shall, upon its review of said audit,
promptly reimburse AASTROM for such overcharge plus interest at a rate of
11/2%/month since the date of payment by AASTROM of the applicable invoice(s).

SECTION 12.  WARRANTY; RECALLS.
             ----------------- 

(a)  Warranty.  MSP warrants to AASTROM that each Cell Cassette and Component
     --------                                                                
shall comply with the then-current Specifications and shall be free from defects
in material and workmanship and shall be manufactured and assembled in
compliance with the DMR and all United States federal, state and local laws,
rules and regulations and with all applicable EN29002 and EN46002 requirements
(and any amendments thereto and replacements thereof), applicable at the time of
manufacture. For a period of one (1) year after delivery to AASTROM, AASTROM
shall have the right to notify MSP that a Cell Cassette or Component does not
conform to this warranty. Such notice shall set forth in detail the reason for
such non-conformance. AASTROM shall prepare for shipment and return to MSP
allegedly defective Cell Cassette or Component in accordance with MSP's written
directions and at MSP's cost. Upon reasonable verification of noncompliance with
this warranty, MSP shall repair a defective and non-conforming Cell Cassette or
Component or, at its option, replace a defective Cell Cassette or Component with
non-defective, conforming units within thirty (30) days after receipt of notice
from AASTROM of the nonconformance. However, if in MSP's reasonable judgment
such repair or replacement cannot be accomplished within said time, MSP shall
issue to AASTROM a credit for the price of each unit of Cell Cassette or
Component verified as defective. All shipping and other costs incurred in
connection with the repair or replacement of all such nonconforming Cell
Cassette or Component units shall be paid by MSP. The foregoing warranty shall
not apply to the extent that the non-conformance is due to a defective component
supplied by AASTROM or compliance with the Specifications as supplied by
AASTROM. Notwithstanding any statutory or other law to the contrary, it is
understood that the foregoing one (1) year warranty period begins on delivery of
the Cell Cassette or Component to AASTROM regardless as to when a defect in a
Cell Cassette or Component may be discovered.

(b)  DISCLAIMER.  THE WARRANTY SET FORTH IN SECTION 12(a), ABOVE, IS GIVEN TO
     ----------                                                              
AASTROM ONLY AND IS IN LIEU OF ALL OTHER WARRANTIES, WHETHER EXPRESSED BY
AFFIRMATION, PROMISE, DESCRIPTION, MODEL, SAMPLE OR OTHERWISE. ANY AND ALL OTHER
WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR USE OR PURPOSE, ARE HEREBY
DISCLAIMED. THE REMEDIES SET FORTH IN THIS AGREEMENT SHALL BE AASTROM'S
EXCLUSIVE REMEDIES FOR DEFECTIVE AND NONCONFORMING PRODUCTS.

(c)  No Third-Person Warranty.  AASTROM will not make any warranty,
     ------------------------                                      
representation or guaranty to any person, either orally or in writing, in the
name of or on behalf of MSP.

(d)  Recalls.  From time to time throughout the Term, AASTROM may in its
     -------                                                            
discretion determine that it is necessary or advisable to recall Cell Cassettes
manufactured by MSP. In such event, if AASTROM reasonably determines that the
number of reported incidence of defective Cell Cassettes is high in relation to
AASTROM's historical incidence rate for defective Cell Cassettes and/or general
medical product industry standards and AASTROM recalls one or more Shipment Lots
due to a failure of such units to meet Specifications during the Warranty
Period, AASTROM shall so notify MSP of the recall and the Parties shall jointly
exchange relevant information and consult on causation of the defective units
prior to

                                     -16-

<PAGE>
 
implementing the recall. In the event it is determined by the Parties that the
Cell Cassettes were defective due to a failure of such units to meet
Specifications during the Warranty Period, MSP agrees to reimburse AASTROM for
the reasonable direct costs incurred by AASTROM in conjunction with the recall
including the cost of replacing, shipping and testing the units of the Shipment
Lot(s) recalled, whether or not all such units are ultimately determined to have
been defective, by way of a reduction in MSP's applicable mark-up rates (as set
forth on Appendix III) to 15% until the cost of the recall has been recovered by
AASTROM. Any disputes regarding causation of defective units involved in a
recall that cannot be resolved by the Parties will be resolved through
arbitration in accordance with Section 24(b). Furthermore, in the event this
Agreement is terminated for any reason prior to AASTROM recovering the full
amount of its recall costs from MSP, MSP shall promptly pay to AASTROM the
amount of any unreimbursed costs. For the purpose of clarification, it is agreed
that AASTROM shall be solely responsible for determining whether any product
recall, correction or withdrawal is required and for complying with all of the
medical device reporting requirements pursuant to 21 CFR Part 803.

related matter.

(b)  MSP's General Indemnity.  MSP will indemnify, hold harmless and defend
     -----------------------                                               
AASTROM and its parents and affiliates and its and their officers, directors,
agents, employees and contractors and their successors and assigns (individually
and collectively, the "AASTROM Indemnitees") from and against any and all loss,
liability, cost, damage and expense (collectively, "Losses"), including without
limitation, reasonable attorneys' fees, in connection with any claims made by
third parties, including without limitation, a governmental agency or other
entity, against any of the AASTROM Indemnitees for any product liability claim
arising out of or in connection with the breach of any of MSP's warranties or
obligations hereunder; provided, that notwithstanding anything in this Agreement
to the contrary, MSP's total liability under this Section 14(b) shall not
exceed* dollars, and AASTROM's indemnity set forth in Section 14(a), above,
shall not be affected or limited by Losses that are in excess of MSP's
indemnification obligations under this Section 14(b). Upon the receipt of a
claim of indemnification hereunder, AASTROM shall give MSP prompt notice thereof
and shall, at no out-of-pocket expense to AASTROM, cooperate with MSP with
respect to the defense of such matter. AASTROM shall have the right, without
affecting its indemnity rights hereunder, to participate in the administration,
defense or settlement of any such matter at its own expense and with counsel of
its own choosing, but MSP will control the defense and selection of lead defense
counsel. MSP's counsel shall give due consideration to suggestions of AASTROM's
counsel and MSP shall not settle any claim indemnified hereunder unless AASTROM
is given a full and unconditional release in respect of such matter.

(c)  Intellectual Property Warranty.
     ------------------------------ 

     (1) AASTROM represents and warrants that neither the design nor
Specifications furnished by AASTROM to MSP in connection with this Agreement nor
the manufacture or sale of Cell Cassettes to such design or Specifications or in
conformance with the DMR (but

excluding any of MSP's manufacturing process or methods that may be incorporated
into any of the foregoing by MSP), will infringe any United States or foreign
patent, trademark, copyright or other intellectual property right of others.

     (2) MSP represents and warrants to AASTROM that no manufacturing process or
method employed by MSP to manufacture the Cell Cassettes will infringe any
United States or foreign patent, trademark, copyright or other intellectual
property right of others; provided that, such process or method was developed
by, or originated from, MSP but without regard to whether such process or method
is incorporated in the Specifications or DMR.

     (3) Without prejudice to the rights of MSP or AASTROM as set forth in
Sections 14(d) and 14(e) below, respectively, if the manufacture or sale of Cell
Cassettes to such design Specifications or DMR or the manufacturing process or
method, respectively, is held to constitute an infringement of any intellectual
property right of any third party or to result in such wrong, and such
manufacture and sale is enjoined (by temporary, preliminary or permanent
injunction), AASTROM or MSP, as the case may be, at its own expense, shall use
its best diligent efforts to procure for the other party the right to continue
to manufacture and sell Cell Cassettes, as applicable.

(d)  Intellectual Property Indemnity by AASTROM.  AASTROM will indemnify, hold
     ------------------------------------------                               
harmless and defend the MSP Indemnitees from and against any and all
liabilities, costs and expenses, including, without limitation, reasonable
attorneys' fees, with respect to which a claim is made by a third party against
any of the MSP Indemnitees arising out of or in connection with the breach of
AASTROM's warranty and representation set forth in Section 14(c), above. Upon
receipt of a claim indemnified hereunder, MSP shall give AASTROM prompt notice
thereof and shall, at no out-of-pocket expense to MSP, cooperate with AASTROM
with respect to the defense of such matter. MSP shall have the right, without
affecting its indemnity hereunder, to participate in the administration, defense
or settlement of any such matter at its own expense and with counsel of its own
choosing, but AASTROM will control the defense and selection of lead defense
counsel. AASTROM's counsel shall give due consideration to suggestions of MSP's
counsel. AASTROM shall not settle any claim indemnified hereunder unless MSP is
given a full and unconditional release in respect of such matter and any related
matter.

(e)  Intellectual Property Indemnity by MSP.  MSP will indemnify, hold harmless
     --------------------------------------                                    
and defend the AASTROM Indemnitees from and against any and all liabilities,
costs and expenses, including, without limitation, reasonable attorneys fees,
with respect to which claim is made by a third party against any of the AASTROM
Indemnities arising out of or in connection with the breach of MSP's warranty
and representation set forth in Section 14(c), above. Upon receipt of a claim
indemnified hereunder, AASTROM shall give MSP prompt notice thereof and shall,
at no out-of-pocket expense to AASTROM, cooperate with MSP with respect to the
defense of such matter. AASTROM shall have the right, without affecting its
indemnity hereunder, to participate in the administration, defense or settlement
of any such matter at its own expense and with counsel of its own choosing, but
MSP will control the defense and selection of lead defense counsel. MSP's
counsel shall give due consideration to suggestions of AASTROM's counsel. MSP
shall not settle any claim indemnified hereunder unless

                                     -20-
<PAGE>
 
AASTROM is given a full and unconditional release in respect of such matter
and any related matter.

SECTION 15.  OWNERSHIP OF INTELLECTUAL PROPERTY.
             ---------------------------------- 

(a)  Ownership of Intellectual Property.  Each Party shall retain and own (vis a
     ----------------------------------                                         
vis the other Party) all right, title and interest to all copyrightable
material, inventions, trademarks, trade secrets, trade dress or other
intellectual property (collectively, "Intellectual Property") which it now owns.
Notwithstanding the foregoing, AASTROM shall own all Intellectual Property and
documentation generated by MSP in connection with the collaborative development
and manufacture of Cell Cassettes, whether or not such Intellectual Property was
generated prior to or after the Effective Date, except for Intellectual Property
that relates to the molding and fabrication processes performed by MSP and the
know-how in connection therewith. Said documentation to be owned by AASTROM
shall include but not be limited to the Specifications, DMR documentation,
material lists, supplier lists and descriptions of manufacturing methods and
processes for manufacture of the Cell Cassettes (hereinafter, the "AASTROM
Documentation"). Furthermore, notwithstanding anything contained herein, MSP
acknowledges and agrees that the AASTROM Documentation will not embody or
constitute the Intellectual Property of MSP. Nothing in this Agreement shall be
deemed to grant a license to either Party under or with respect to the
Intellectual Property of the other Party.

(b)  Return of Intellectual Property.  Upon expiration of the Term or upon any
     -------------------------------                                          
earlier termination of this Agreement, MSP shall promptly transfer to AASTROM
all AASTROM Documentation and Intellectual Property within MSP's possession or
control, and AASTROM shall promptly transfer to MSP all MSP Intellectual
Property within AASTROM's possession or control. Furthermore, in the event of
any expiration or termination of this Agreement by AASTROM "for cause" pursuant
to Section 17, or by MSP, other than in accordance with Section 17, MSP will
provide AASTROM with full cooperation with regard to the transfer of any know-
how embodied in AASTROM Documentation that is sufficient to allow AASTROM to
manufacture the Cell Cassettes pursuant to this Agreement; provided that, except
                                                           -------- ----
for copying, MSP shall bear no expense of any nature in connection
therewith.

SECTION 16.  CONFIDENTIAL INFORMATION.
             ------------------------ 

(a)  Title to Confidential Information and Related Documents.  Title to
     -------------------------------------------------------           
Confidential Information provided by the Disclosing Party to the Recipient shall
be and remain the sole and exclusive property of the Disclosing Party. Recipient
shall return all such Confidential Information, together with all copies
thereof, except for one archive copy, promptly upon the termination of this
Agreement.

(b)  Non-Disclosure and Non-Use of Confidential Information.  The Recipient
     ------------------------------------------------------                
shall hold all Confidential Information disclosed to it pursuant to this
Agreement in confidence and will use Confidential Information only for the
purpose of performing its obligations under this Agreement and for no other
purpose whatsoever. The Recipient will not disclose Confidential Information to
any third person and will disclose Confidential Information only to such of its
employees as is necessary or reasonably appropriate to the performance of the
Recipient's

                                     -21-
<PAGE>
 
obligations under this Agreement. Recipient shall ensure that its employees and
any permitted subcontractors having access to the Confidential Information of
the Disclosing Party have previously agreed, either as condition of employment
or to obtain the Confidential Information, to be bound by terms and conditions
substantially similar to those found in this Section 16(b) as a condition to
such access. In the event that the Recipient is requested or required by court
or governmental order to disclose any of the Confidential Information, the
Recipient shall provide the Disclosing Party with prompt written notice of such
request or requirement so that the Disclosing Party may seek a protective order
or other appropriate protection. The Recipient will cooperate with Disclosing
Party at the Disclosing Party's expense, to obtain an appropriate protective
order or other reliable assurance that confidential treatment will be accorded
confidential treatment by such court or governmental entity.

(c)  Protection of Confidential Information.  The Recipient will observe
     --------------------------------------                             
reasonable precautions and procedures to protect and preserve Confidential
Information to the same extent that the Recipient uses with respect to its own
like confidential information.

SECTION 17.  TERM AND TERMINATION.
             -------------------- 

(a)  Term of Agreement.  The Term shall commence upon the Effective Date and
     -----------------                                                      
continue until its expiration on the seventh anniversary of the Effective Date,
unless earlier terminated as provided in this Agreement.

(b)  Termination Upon Default.  Except for a failure and the corresponding
     ------------------------                                             
remedy as expressly specified in Sections 3, 12 and 17(d), if either Party shall
commit a material default in any of the material terms or obligations under this
Agreement, the non-defaulting Party shall have the right to give the defaulting
Party notice specifying with particularity the default and the circumstances
surrounding the default. If the defaulting Party shall fail to cure, the noticed
default within thirty (30) days after receipt of such notice (fifteen business
days with respect to non-payment of amounts owed by AASTROM to MSP under this
Agreement), the non-defaulting Party shall have the right to terminate this
Agreement prospectively by giving the defaulting Party further notice of at
least twenty (20) days prior to the effective date of termination set forth in
such further notice.

(c)  Termination Upon Insolvency.  Either Party shall have the right to
     ---------------------------                                       
terminate this Agreement prospectively by notice of at least ten (10) days to
the other Party if the Party receiving such notice has filed a petition in
bankruptcy or insolvency (or if such petition is filed against it and is not
vacated, stayed or bonded within one hundred and twenty (120) days after such
filing), or files a petition or answer seeking reorganization, readjustment or
rearrangement of a substantial part of its business under any law relating to
bankruptcy or leading to bankruptcy or is adjudicated by a competent regulatory
agency to be bankrupt or insolvent, or a receiver is appointed for all or
substantially all of the property of such other Party, or an assignment is made
for the benefit of the creditors of such other Party, or any proceeding are
instituted for the liquidation or winding up of the business of such other
Party.

(d)  Termination Upon Inability of MSP to Perform.  If, on any three occasions
     --------------------------------------------                             
within a twelve-month period during the Term of this Agreement, one or more
of the following events

                                     -22-
<PAGE>
 
occur, then AASTROM shall have the right to notify MSP that AASTROM intends to
terminate this Agreement prospectively, specifying an effective date of
termination not less than thirty (30) days after the date of such notice: (i)
more than ten (10%) percent of the Shipment Lots or units of Cell Cassettes
delivered to AASTROM are properly rejected by AASTROM under Section 3(f), above;
(ii) more than 1 of 1,000 Cell Cassettes accepted by AASTROM fail to meet the
warranty set forth in Section 12(a); or (iii) MSP fails to timely deliver a
complete order of Cell Cassettes meeting Specifications. For purposes of this
Section 17(d), the term "timely deliver" shall mean delivery not more than ten
(10) days prior to, nor more than five (5) days after, scheduled delivery dates.
The foregoing right of termination shall be in addition to AASTROM's right to
seek damages available under law subject to the limitations set forth in Section
13.

(e)  Effect of Termination.  Termination of this Agreement by either Party shall
     ---------------------                                                      
not affect any purchase order submitted by AASTROM to MSP pursuant to the terms
of this Agreement prior to the effective date of termination and the Parties
shall fulfill their obligations under such purchase order or to be undertaken
under this Agreement prior to such termination even if the completion of such
obligations shall be after the effective date of termination. Notwithstanding
the foregoing, upon any termination of this Agreement by AASTROM pursuant to
this Section 17, AASTROM may, in its discretion elect to terminate all in-
process manufacturing of Cell Cassettes by MSP and MSP shall terminate such
manufacturing effective immediately upon notice from AASTROM. Furthermore, upon
the expiration of the Term as specified in Section 17(a), or upon the
termination of this Agreement other than a termination by AASTROM as permitted
by Sections 17(b), (c) or (d), then AASTROM shall purchase, at the price set
forth in this Agreement, all Cell Cassette finished goods, work in process and
unique materials that have been purchased by MSP prior to the effective date of
this Agreement for the manufacture of Cell Cassettes provided that the
quantities of such goods and materials are reasonable in light of AASTROM's
forecasted Requirements and provided that such goods and materials are not
defective (per the Specifications). Without limiting the generality of the
foregoing, to the extent necessary to give effect to the intention of the
Parties expressed therein, the obligations of the Parties under Sections 10
("Equipment"), 11(d) ("Records; Inspection"), 12 ("Warranty; Recalls"), 13
("Limitation of Damages Liability"), 14 ("Indemnity"), 15 ("Ownership of
Intellectual Property"), 16 ("Confidential Information"), 17 ("Term and
Termination"), 18 ("Preferred Supplier; Alternative Supplier"), 19
("Representations and Warranties"), 23 ("Similar Products"), 24 ("Governing Law;
Dispute Resolution"), 25 ("Notices"), 28 ("Severability"), 29 ("Amendment and
Waiver") and 32 ("Entire Agreement") shall survive termination of this Agreement
in accordance with their terms.

(f)  Liabilities When No Termination.  Notwithstanding the foregoing, in the
     -------------------------------                                        
event that MSP is in material breach of any of its warranties or obligations,
and such breach does not allow AASTROM to terminate this Agreement pursuant to
Section 17, then MSP shall be subject to the liabilities and remedies available
at law and by this Agreement for such breach, subject to the limitations set
forth in Section 13.

(g)  Alternative Purchase of Product.  If MSP is in breach of MSP's obligations
     -------------------------------                                           
to make and sell Cell Cassettes or Components as specified in this Agreement,
and such breach does not

                                     -23-
<PAGE>
 
result in a termination of this Agreement, and if AASTROM has available an
alternative manufacturing source for said Cell Cassettes or Components, then
AASTROM may cancel all or any part of any pending purchase orders (which
purchase orders are within the quantities specified in the 12-month rolling
forecast as specified in Section 3(a) hereof) for which MSP is unable or
unwilling to accept and perform; and AASTROM may have said purchase orders
performed by the alternative manufacturing source; and any damages suffered by
AASTROM as a result of MSP's breach shall still be recoverable against MSP
(subject to the limitations specified in Section 13 hereof).

SECTION 18.  PREFERRED SUPPLIER; ALTERNATIVE SUPPLIER.
             ---------------------------------------- 

(a)  Preferred Supplier.  During the Term, AASTROM shall regard MSP as its
     ------------------                                                   
"preferred supplier" for Cell Cassettes and purchase its Requirements from
MSP; provided, however, nothing in this Agreement shall be deemed to
     --------  -------                                              
preclude AASTROM from manufacturing the remaining forty (40%) percent of
AASTROM's total requirements for Cell Cassettes by itself or from utilizing
alternate suppliers for such manufacture.

(b)  Alternate Suppliers.  In the event that AASTROM elects to utilize an
     -------------------                                                 
alternative supplier for the Cell Cassettes during the Term, MSP shall provide
reasonable cooperation by promptly supplying AASTROM with copies of all AASTROM
Documentation at the reasonable expense of AASTROM; provided, however nothing
                                                    --------  ------- 
in this Section 18(b) shall be deemed to require MSP to provide training or
consultation services to the alternate supplier with regard to the manufacture
of the Cell Cassettes.

SECTION 19.  REPRESENTATIONS AND WARRANTIES.  MSP and AASTROM each represents
             ------------------------------                                  
and warrants (1) that each has, respectively, the full right and authority to
enter into this Agreement, and nothing provided in this Agreement will conflict
in any way with any outstanding obligation, contractual or otherwise, of such
Party, and (2) that each shall comply with all United States governmental laws,
rules, regulations and orders applicable to its obligations under this
Agreement.

SECTION 20.  FORCE MAJEURE.
             ------------- 

(a)  Suspension of Performance.  In the event that MSP or AASTROM (other than
     -------------------------                                               
with respect to its obligations to pay money to MSP) is rendered unable, wholly
or in part, to carry out its obligations under this Agreement by reasons of acts
of God, industrial disturbances, outbreak of a state of emergency, war,
hostilities, civil commotion, riots, epidemics, fires, earthquakes, floods or
any other cause or causes similar or dissimilar to the foregoing beyond the
reasonable control of the Party claiming benefit of force majeure, upon such
Party's giving notice and reasonably full particulars of such reason to the
other Party within a reasonable time after the occurrence of the cause relied
upon, then the obligations of the Party giving such notice, so far as they are
affected by such reason, shall be suspended during the continuation of any
inability so caused, but no longer, and such cause shall so far as reasonably
possible be remedied with all reasonable dispatch without the necessity of
expending sums (including, without limitation, for overtime labor) not otherwise
required under this Agreement. When the event operating to suspend performance
by either Party

                                     -24-
<PAGE>
 
shall cease, this Agreement shall continue in full force and effect until
the expiration or earlier termination as provided in this Agreement.

(b)  Cooperation.  In the event of a force majeure, AASTROM and MSP shall
     -----------                                                         
communicate and cooperate in seeking to avoid or minimize potential interruption
of supply and to develop mutually acceptable contingency plans in the spirit of
this Agreement.  In any event, the time for a Party's performance under this
Agreement shall be extended to the extent reasonably necessary to perform the
suspended obligation.

(c)  Allocation of Resources.  In the event of a force majeure resulting in a
     -----------------------                                                 
partial inability of MSP to supply product to its customers, MSP may allocate
resources that have not specifically been earmarked to this Agreement, to all of
its customers in an equitable manner as determined solely by MSP.

Section 21.  MSP Competitiveness; Shared Investment Return.
             --------------------------------------------- 

(a)  MSP's Competitiveness.  The Parties acknowledge that a primary
     ---------------------                                         
consideration for AASTROM with regard to the selection of MSP as its preferred
supplier was MSP's expertise and stated intention to be a cost-effective and a
capable manufacturer and supplier of Cell Cassettes and Components and that
AASTROM's commercialization strategy is dependent in part upon MSP's stated
intention to use best diligent efforts to remain cost effective and capable.
Thus, MSP will use best diligent efforts to search for methods and means that
will lead to in-plant cost reductions, savings and maintenance and quality
improvement. AASTROM will cooperate with MSP in these efforts.

(b)  Shared Investment Return.
     ------------------------ 

     (1) MSP Capital Investments.  If, during the Term, MSP shall invest in an
         -----------------------                                              
AASTROM-approved capital project that results in a cost savings in the
production of Cell Cassettes, MSP shall be entitled to retain such cost savings
until MSP has recouped the entire cost of the capital project from Cell
Cassettes purchased by AASTROM.  Once MSP recoups such capital expenditure, the
cost savings resulting from implementation of the capital expenditure shall be
shared by the Parties on a 50%:50% basis and MSP shall be deemed to have
assigned to AASTROM sole ownership of the capital property purchased by MSP such
that the capital property shall be AASTROM's Equipment.  Throughout the Term,
any such capital property purchased by MSP shall be used by MSP solely for the
manufacture of Cell Cassettes for AASTROM.  The method for recoupment of MSP's
capital investments and implementation of cost sharing shall be as set forth in
Section 21(b)(2) below.

     (2) Recoupment of MSP Capital Investment; Cost Sharing.  Effective on the
         --------------------------------------------------                   
first day of the quarter immediately following the quarter in which a capital
project paid for by MSP is implemented and cost savings first occur, the Base
Cost Assumption (calculated in accordance with Appendix III) shall be
recalculated (RBCA) to reflect the cost savings resulting from implementation of
the capital project.  The difference between the original Base Cost Assumption
(OBCA) and RBCA shall be tracked by MSP on future orders of Cell Cassettes and
the entire cost savings shall be allocated to MSP until MSP has recouped the

                                     -25-
<PAGE>
 
amount MSP expended on the capital project.  Thereafter, the cost savings
resulting from implementation of the capital expenditure shall be allocated to
AASTROM and MSP on a 50%:50% basis with regard to all Cell Cassette orders
submitted by AASTROM.

     (3) AASTROM Capital Investments.  AASTROM shall enjoy all savings that
         ---------------------------                                       
result from capital projects that are paid for by AASTROM or result from any
changes in Specifications made by AASTROM.  In the event that any such cost
savings are implemented, the Base Cost Assumption utilized to calculate
AASTROM's purchase price for Cell Cassettes shall be immediately reduced to
reflect the amount of the cost savings.  AASTROM shall also retain all ownership
rights with regard to any capital property purchased by AASTROM which may be
used by MSP in the manufacture of Cell Cassettes for AASTROM.

SECTION 22.  INSURANCE.
             --------- 

During the Term, each Party shall procure and maintain at its own cost and
expense, including the cost of premiums and deductibles, a general liability
insurance policy, including product liability (completed operations) insurance,
in an amount not less than* dollars per occurrence,* dollars aggregate bodily
injury, death and property damage liability and commercial umbrella coverage of
at least* dollars each occurrence and annual aggregate. Such insurance shall be
written by a reputable insurance company licensed to do business in the United
States, shall name the other Party as an additional insured, shall contain a
broad form vendor's endorsement. During Term, MSP shall also carry and maintain
in full force and effect all-risk property insurance covering the full
replacement value of AASTROM's Equipment and MSP's building, machinery,
equipment and work-in-process, as well as worker's compensation insurance in the
statutory limits required by the State of North Carolina (or other applicable
jurisdiction). Within ten (10) days after the Effective Date, each Party shall
furnish the other Party with a certificate of insurance confirming the existence
of such insurance and stipulating that the insurer will give the other Party at
least ten (10) days' written notice prior to any cancellation of or material
change in such insurance. The availability of the foregoing insurance coverage
shall in no event be construed to limit or expand the Parties' agreement to
limit liability to one another in accordance with Section 13.

SECTION 23.  SIMILAR PRODUCTS.
             ---------------- 

(a)  Continuing Prohibition.  At all times both during and after the Term, MSP
     ----------------------                                                   
shall not make or sell, or enable others to make or sell, the Cell Cassettes
or Components, excepting only for making and selling the Cell Cassettes or
Components for AASTROM.

(b)  Similar Products.  During the Term, MSP shall not (i) manufacture,
     ----------------                                                  
assemble, produce, ship or in any other way make available for use or
distribution, by any party other than AASTROM, any product or system that is
functionally the same as the Cell Cassette or Components, or (ii) in any way
accept engagement with, or render service to, any individual, firm or
corporation, other than AASTROM, as a consultant, instructor, expert, designer,
manufacturer or producer, or act in any other capacity, which engagement or
rendition of

----------

                                     -26-
<PAGE>
 
services involves the development or production of any product or system that
performs the same function as the Cell Cassette. Furthermore, in the event that
this Agreement is terminated by AASTROM "for cause" under Section 17, the
foregoing prohibitions shall continue until twelve (12) months after the

components than are used for the Cell Cassette.

SECTION 24.  GOVERNING LAW; DISPUTE RESOLUTION.
             --------------------------------- 

(a)  Governing Law.  The construction, interpretation and enforcement of the
     -------------                                                          
terms, conditions, rights and liabilities set forth in this Agreement shall
be in accordance with the internal laws of the State of New York, excluding
its conflict-of-laws principles.

(b)  Dispute Resolution.
     ------------------ 

     (1)  Any controversy or claim arising out of or relating to this Agreement
or the breach thereof, whether common law or statutory, including, without
limitation, claims asserting violations or the antitrust laws, will be settled
exclusively by arbitration in New York, New York if initiated by AASTROM and in
Ann Arbor, Michigan, if initiated by MSP (unless another location is mutually
agreed in writing), using the American Arbitration Association.  The arbitration
will be heard before three arbitrators, one to be chosen by AASTROM, one to be
chosen by MSP, and the third to be chosen by those two arbitrators.

     (2)  The arbitrators will apply the internal law of the State of New York
as set forth in Section 24(a), except that the arbitrators will not have the
power to alter, modify, amend, add to or subtract from any term or provision of
this Agreement.  To the extent consistent with the terms of this Agreement, the
arbitrators shall have the power to grant injunctive relief.  In all other
respects, the Commercial Rules of the American Arbitration Association will
govern the arbitration.  Judgment on the award of the arbitrators may be entered
by any court having jurisdiction to do so, and the parties to this Agreement
hereby irrevocably consent and submit to the personal jurisdiction and venue of
the applicable federal courts having jurisdiction in the district and state in
which the arbitration is to occur, if at all, in accordance with this Section
24(b) (or in the state court in the county and state in which the arbitration is
to occur, if at all, failing jurisdiction of the federal court) in any action or
proceeding for that purpose as well as for any and all other permitted purposes,
including, without limitation, in respect of a Party seeking injunctive relief,
in connection with this Agreement.  The Parties hereby irrevocably waive any and
all claims and defenses either might otherwise have in any such action or
proceeding in any of such courts based upon any alleged lack of personal
jurisdiction, improper venue, forum non conveniens or any similar claim or
                              ----- --- ----------                        
defense.

     (3)  The failure or refusal of either Party to submit to arbitration as
required by Section 24(b) will constitute a material breach of this Agreement.
If judicial action is commenced in order to compel arbitration, and if
arbitration is in fact compelled, the Party that resisted arbitration will be
required to pay to the other parties all costs and expenses, including,

                                     -27-
<PAGE>
 
without limitation, reasonable attorneys' fees, that they incur in compelling
arbitration.  The prevailing Party in arbitration shall be entitled to its
reasonable attorneys' fees and costs of the arbitration proceeding without
regard to the limitations set forth in Section 13.  All other fees and charges
of the American Arbitration Association will be borne as the arbitrators will
determine in their award.

(c)  Notwithstanding the Parties' agreement to submit to arbitration pursuant to
this Section 24, either Party may petition any court of competent
jurisdiction for injunctive relief in the event of an alleged breach of
Section 15(b) or 16.

SECTION 28.  SEVERABILITY.
             ------------ 

In case any provision or part thereof in this Agreement shall, for any reason,
be held invalid, illegal or unenforceable, such invalidity, illegality or
unenforceability shall not affect any other provision or part thereof, and this
Agreement shall be construed as if such invalid or illegal or unenforceable
provision or part thereof had been reformed so that it would be valid, legal and
enforceable to the maximum extent permitted.  Except as otherwise expressly set
forth in this Agreement, neither Party shall have the right to set off all or
any part of the damages it incurs as a result of the other Party's breach of its

provision hereof shall in no manner affect the Party's right at a later time to
enforce the same.  No waiver by any Party of the breach of any term contained in
this

                                     -29-

Prior to the commencement of Phase II, the Parties shall negotiate in good faith
using best diligent efforts to reach a mutual agreement with regard to the
establishment of a fair and

reasonable purchase price for Cell Cassettes during Phase II in accordance with
the provisions of this Section B.

1.   Base Cost Assumption
     --------------------

As part of Phase I development, and prior to the commencement of Phase II, the
Parties will develop a bill of materials which sets forth the cost to produce a
Cell Cassette on a per unit basis assuming an annual production volume of 1,000
Cell Cassettes, hereafter referred to as the "Base Cost Assumption."  Such bill
of materials will be substantially in the form of Appendix V to be attached
hereto (hereinafter, the "Bill of Materials") and the Parties will use best
diligent efforts to mutually agree upon the cost assumptions underlying the Base
Cost Assumption.  Such assumptions shall be based upon manufacturing costs
determined in accordance with Generally Accepted Accounting Principles.

2.   Adjustment to the Base Cost Assumption
     --------------------------------------

A primary consideration in AASTROM's decision to select MSP as its preferred
supplier is MSP's stated intention and capability to use its best diligent
efforts to manufacture Cell Cassettes at the lowest reasonable cost.  As
manufacturing experience and unit and lot volumes increase, certain
manufacturing cost components are expected to decrease.  As part of its
undertaking to use best diligent efforts to capture such decreases, prior to
commencement of Phase II, MSP will meet with AASTROM (and its representatives)
to review, and carry out other activities as necessary to:

     (i)   establish the Bill of Materials for the Cell Cassette which will
include quantities and costs of purchased materials and labor hours and rates
for molding and assembly operations (see Appendix V);
     (ii)  identify the cost components that will be impacted by increased
production volumes;
     (iii) identify methods of improving manufacturing efficiencies in molding
and assembly operations expected to result in manufacturing yield improvements
from experience and volume increases; and
     (iv)  identify methods of improving the economies of procuring raw
materials and other third party components, including without limitation, volume
purchasing, and materials handling and procurement methods.

Once the Base Cost Assumption has initially been established, the Parties will
periodically review the assumptions underlying the Base Cost Assumption and
effect appropriate adjustments to the Base Cost Assumption to reflect changes to
the Bill of Materials including the then-current cost of purchased materials and
labor rates.  Based upon this review process (hereafter referred to as the "Cost
Review Process"), AASTROM and MSP will also establish the appropriate expected
cost reductions that are achievable by MSP at increased manufacturing volumes
and which MSP shall become responsible for achieving upon reaching an annual
Phase II production volume of* Cell Cassettes. Such cost reductions, as agreed
to by the Parties, will be referred to as MSP's Cost Reduction Commitment and
will include those cost reductions resulting from manufacturing efficiencies
achievable from

increased manufacturing volume as well as improvements in manufacturing yield as
MSP becomes more proficient in producing Cell Cassettes (hereafter referred to
as "Manufacturing Yield). Upon AASTROM reaching an annual order volume of*
Cell Cassettes, the Parties will agree on MSP's cost Reduction Commitment to be
implemented at an annual order volume of* units. Concurrently with MSP's
efforts to implement cost reductions, AASTROM will endeavor to make design and
manufacturing process changes that will result in additional manufacturing cost
reductions (hereinafter referred to as "AASTROM Cost Reductions"). Such AASTROM
Cost Reductions will be reflected in the Base Cost Assumption. For example,
assuming a* per unit Base Cost Assumption, once AASTROM's annual order
volume reaches* Cell Cassettes, the Base Cost Assumption would be reduced
by MSP's Cost Reduction Commitment of (assuming* as MSP's Cost Reduction
Commitment) reducing the Base Cost Assumption to*. If AASTROM modified the
Specifications to allow for a $20 component to be used in place of a $50
component, the resulting $30 cost savings would further be deducted from the
Base Cost Assumption reducing it to*.

Upon the achievement of an annual production volume of* Cell Cassettes,
the Parties will again diligently undertake a Cost Review Process to determine
subsequent MSP Cost Reduction Commitments at annual production volume increments
of* Cell Cassettes.  The Cost Review Process shall not, however, be deemed
to relieve MSP from undertaking to use best diligent efforts to reduce costs
during any intervening periods wherein the parties are reviewing MSP's Cost
Reduction Commitment.

3.   Mark-Up, Cell Cassette Purchase Price
     -------------------------------------

Prior to the commencement of Phase II and not less than 30 days prior to
expiration of each subsequent calendar year during Phase II thereafter, AASTROM
shall advise MSP of its annual forecast of Cell Cassettes needed from MSP for
the following year and MSP will receive a manufacturing Mark-Up to be determined
each year based upon AASTROM's annual forecast and the manufacturing operations
to be undertaken by MSP as follows;

                     AASTROM Annual Volume Forecast (Units)

Cell Cassette Purchase Price - Once the annual percent Mark-Up has been
----------------------------                                           
determined for the year, the Purchase Price for the Cell Cassettes to be
delivered to AASTROM for that year will be as follows;

     * (*)  = Purchase Price.

(*) the applicable Mark-Up rates will be based upon AASTROM's annual volume
forecast using the above table.  Once AASTROM's annual volume forecast reaches
a* Cell Cassettes increment, the Base Cost Assumption will be reduced by
MSP's Cost Reduction Commitment on all subsequent purchase orders submitted by
AASTROM, as provided in Section B.2 above, and any AASTROM Cost Reductions would
then be additionally deducted.

Such Purchase Price will be used by MSP to invoice AASTROM for Cell Cassettes
delivered under this Agreement during the following year.

Annual Adjustment - Costs - Within 30 days after the expiration of each year
-------------------------                                                   
during Phase II, the actual average MSP manufacturing cost to produce a Cell
Cassette will be compared to the Base Cost Assumption, as adjusted, applicable
during the preceding year.  For purposes of this Section B3, the Base Cost
Assumption shall be adjusted to reflect the changes to price of purchased raw
materials and component parts and labor rates.  The Base Cost Assumption shall
not be adjusted for increases in cost resulting from activities within MSP's
control, including but not limited to, manufacturing efficiencies and
manufacturing yield.  If the actual average unit cost is less than such Base
Cost Assumption, then AASTROM shall be entitled to a credit for the difference
between the Base Cost Assumption, as adjusted, and the actual average unit cost
multiplied by the total number of units purchased by AASTROM during the
preceding year.  Such credit will be paid to AASTROM by MSP within 45 days after
AASTROM and MSP have completed the cost review.  Alternatively, if the actual
unit cost exceeds the Base Cost Assumption, as adjusted, AASTROM shall only be
obligated to pay MSP for Cell Cassettes it accepted at the Cell Cassette
Purchase Price in effect at the time the Order was submitted by AASTROM.  For
purposes of determining the actual manufacturing costs as set forth in this
Section B.3, the provisions of Section A 2(a), 2(d), 2(e), 2(g) and (h) of this
Appendix III shall apply, provided however that increases in those cost rates
will not exceed the amount of any increase in the Producer Price Index over the
applicable period and there shall be no mark-up on costs described in items 2(h)
nor shall there be any mark-up on freight, taxes, insurance, sterility
validation or other similar add-on charges with regard to costs directly billed
to AASTROM or for materials supplied directly by AASTROM.

Annual Adjustment - Mark-Up Rates - At such time as the foregoing annual cost
---------------------------------                                            
adjustment is made, the actual volume of Cell Cassettes ordered by AASTROM
during such year will be compared to the annual forecast for that year.  If the
actual volume of Cell Cassettes ordered and not canceled by AASTROM during such
year is less than the forecasted volume on which the Mark-Up rates were
established, MSP may invoice AASTROM for the difference resulting from the use
of lower than actual Mark-Up rates based upon the volume of Cell Cassettes
actually ordered by AASTROM.  Similarly, if the forecasted volume of Cell
Cassettes

purchased by AASTROM is exceeded in any year, MSP will refund AASTROM for the
difference resulting from the use of higher than actual Mark-Up rates based upon
the volume of Cell Cassettes actually ordered by AASTROM.

Additional Manufacturing Development Activities.
----------------------------------------------- 

During Phase II, AASTROM may request that MSP provide assistance to AASTROM that
is beyond the scope of this Agreement.  In this event, any such costs
preapproved by AASTROM in writing and incurred by MSP will be borne by AASTROM
and paid at rates consistent with Phase I pricing.
