                         COMMON STOCK PURCHASE AGREEMENT

        COMMON STOCK PURCHASE AGREEMENT (the "Agreement"), dated as of October
30, 2002 by and between AASTROM BIOSCIENCES, INC., a Michigan corporation (the
"Company"), and FUSION CAPITAL FUND II, LLC, an Illinois limited liability
company (the "Buyer"). Capitalized terms used herein and not otherwise defined
herein are defined in Section 10 hereof.

                                    WHEREAS:

        Subject to the terms and conditions set forth in this Agreement, the
Company wishes to sell to the Buyer, and the Buyer wishes to buy from the
Company, up to Twelve Million Dollars ($12,000,000) of the Company's common
stock, no par value per share (the "Common Stock"). The shares of Common Stock
to be purchased hereunder are referred to herein as the "Purchase Shares." In
addition, as set forth in Section 1(h) hereof, the Company may, in its sole
discretion, at any time after the date hereof and until 30 days after such date
as the Available Amount is equal to $0, deliver an irrevocable written notice to
the Buyer stating that the Company elects to enter into a second Common Stock
Purchase Agreement with the Buyer for the purchase of an additional Twelve
Million Dollars ($12,000,000) of Common Stock.

        NOW THEREFORE, the Company and the Buyer hereby agree as follows:

        1.     PURCHASE OF COMMON STOCK.

        Subject to the terms and conditions set forth in Sections 6, 7 and 9
below, the Company hereby agrees to sell to the Buyer, and the Buyer hereby
agrees to purchase from the Company, shares of Common Stock as follows:

        (a) Commencement of Purchases of Common Stock. The purchase and sale of
Common Stock hereunder shall commence (the "Commencement") within five (5)
Trading Days following the date of satisfaction (or waiver) of the conditions to
the Commencement set forth in Sections 6 and 7 below (or such later date as is
mutually agreed to by the Company and Buyer) (the date of such Commencement, the
"Commencement Date").

        (b) Buyer's Purchase Rights and Obligations. Subject to the Company's
right to suspend purchases under Section 1(d)(ii) hereof, the Buyer shall
purchase shares of Common Stock on each Trading Day during each Monthly Period
equal to the Daily Purchase Amount (as defined in Section 1(c)(i)) at the
Purchase Price. Within one (1) Trading Day of receipt of Purchase Shares, the
Buyer shall pay to the Company an amount equal to the Purchase Amount with
respect to such Purchase Shares as full payment for the purchase of the Purchase
Shares so received. The Company shall not issue any fraction of a share of
Common Stock upon any purchase. All shares of Common Stock (including fractions
thereof) issuable upon a purchase under this Agreement shall be aggregated for
purposes of determining whether the purchase would result in the issuance of a
fraction of a share of Common Stock. If, after the aforementioned aggregation,
the issuance would result in the issuance of a fraction of a share of Common
Stock, the Company shall round such fraction of a share of Common Stock up or
down to the nearest whole share. All payments made under this Agreement shall be
made in lawful money of the United States of America by check or wire transfer
of immediately available funds to such account as the Company may from time to
time designate by written notice in accordance with the provisions of this
Agreement. Whenever any amount expressed to be due by the terms of this
Agreement is due on any day

<PAGE>

that is not a Trading Day, the same shall instead be due on the next succeeding
day which is a Trading Day.

        (c) The Daily Purchase Amount; Company's Right to Decrease or Increase
the Daily Purchase Amount.

               (i) The Daily Purchase Amount. As used herein the term "Original
        Daily Purchase Amount" shall mean Twenty Five Thousand Dollars ($25,000)
        per Trading Day. As used herein, the term "Daily Purchase Amount" shall
        mean initially Twenty Five Thousand Dollars ($25,000) per Trading Day,
        which amount may be increased or decreased from time to time pursuant to
        this Section 1(c).

               (ii) Company's Right to Decrease the Daily Purchase Amount. The
        Company shall always have the right at any time to decrease the amount
        of the Daily Purchase Amount by delivering written notice (a "Daily
        Purchase Amount Decrease Notice") to the Buyer which notice shall
        specify the new Daily Purchase Amount. The decrease in the Daily
        Purchase Amount shall become effective one Trading Day after receipt by
        the Buyer of the Daily Purchase Amount Decrease Notice. Any purchases by
        the Buyer which have a Purchase Date on or prior to the first (1st)
        Trading Day after receipt by the Buyer of a Daily Purchase Amount
        Decrease Notice must be honored by the Company as otherwise provided
        herein. The decrease in the Daily Purchase Amount shall remain in effect
        until the Company delivers to the Buyer a Daily Purchase Amount Increase
        Notice (as defined below).

               (iii) Company's Right to Increase the Daily Purchase Amount. The
        Company shall have the right (but not the obligation) to increase the
        amount of the Daily Purchase Amount in accordance with the terms and
        conditions set forth in this Section 1(c)(iii) by delivering written
        notice to the Buyer stating the new amount of the Daily Purchase Amount
        (a "Daily Purchase Amount Increase Notice"). A Daily Purchase Amount
        Increase Notice shall be effective five (5) Trading Days after receipt
        by the Buyer. The Company shall always have the right at any time to
        increase the amount of the Daily Purchase Amount up to the Original
        Daily Purchase Amount. With respect to increases in the Daily Purchase
        Amount above the Original Daily Purchase Amount, as the market price for
        the Common Stock increases the Company shall have the right from time to
        time to increase the Daily Purchase Amount as follows. For every $0.25
        increase in Threshold Price above $0.50 (subject to equitable adjustment
        for any reorganization, recapitalization, non-cash dividend, stock split
        or other similar transaction), the Company shall have the right to
        increase the Daily Purchase Amount by up to an additional $5,000 in
        excess of the Original Daily Purchase Amount. "Threshold Price" for
        purposes hereof means the lowest Sale Price of the Common Stock during
        the five (5) consecutive Trading Days immediately prior to the
        submission to the Buyer of a Daily Purchase Amount Increase Notice
        (subject to equitable adjustment for any reorganization,
        recapitalization, non-cash dividend, stock split or other similar
        transaction). For example, if the Threshold Price is $0.75, the Company
        shall have the right to increase the Daily Purchase Amount to up to
        $30,000 in the aggregate. If the Threshold Price is $2.00, the Company
        shall have the right to increase the Daily Purchase Amount to up to
        $55,000 in the aggregate. Any increase in the amount of the Daily
        Purchase Amount shall continue in effect until the delivery to the Buyer
        of a Daily Purchase Amount Decrease Notice. However, if at any time
        during any Trading Day the Sale Price of the Common Stock is below the
        applicable Threshold Price, such increase in the Daily Purchase Amount
        shall be void and the Buyer's obligations to buy Purchase Shares
        hereunder in excess of the applicable maximum Daily Purchase Amount
        shall be terminated. Thereafter, the Company shall again have the right
        to increase the amount of the Daily Purchase Amount as set forth herein
        by delivery of a new Daily


                                      -2-
<PAGE>

        Purchase Amount Increase Notice only if the Sale Price of the Common
        Stock is above the applicable Threshold Price on each of five (5)
        consecutive Trading Days immediately prior to such new Daily Purchase
        Amount Increase Notice.

        (d) Limitations on Purchases.

               (i) Limitation on Beneficial Ownership. The Company shall not
        effect any sale under this Agreement and the Buyer shall not have the
        right to purchase shares of Common Stock under this Agreement to the
        extent that after giving effect to such purchase the Buyer together with
        its affiliates would beneficially own in excess of 4.9% of the
        outstanding shares of the Common Stock following such purchase and
        provided that the Buyer has delivered to the Company notice that such
        purchase would cause the Buyer together with its affiliates to
        beneficially own in excess of 4.9% of the outstanding shares of the
        Common Stock following such purchase. For purposes hereof, the number of
        shares of Common Stock beneficially owned by the Buyer and its
        affiliates or acquired by the Buyer and its affiliates, as the case may
        be, shall include the number of shares of Common Stock issuable in
        connection with a purchase under this Agreement with respect to which
        the determination is being made, but shall exclude the number of shares
        of Common Stock which would be issuable upon (1) a purchase of the
        remaining Available Amount which has not been submitted for purchase,
        and (2) exercise or conversion of the unexercised or unconverted portion
        of any other securities of the Company (including, without limitation,
        any warrants) subject to a limitation on conversion or exercise
        analogous to the limitation contained herein beneficially owned by the
        Buyer and its affiliates. If the 4.9% limitation is ever reached the
        Company shall have the option to increase such limitation to 9.9% by
        delivery of written notice to the Buyer. Thereafter, if the 9.9%
        limitation is ever reached this shall not affect or limit the Buyer's
        obligation to purchase the Daily Purchase Amount as otherwise provided
        in this Agreement. Specifically, even though the Buyer may not receive
        additional shares of Common Stock in the event that the 9.9% limitation
        is ever reached, the Buyer is still obligated to pay to the Company the
        Daily Purchase Amount on each Trading Day as otherwise obligated under
        this Agreement, e.g. no Event of Default (as defined in Section 9
        hereof) has occurred, nor any event which, after notice and/or lapse of
        time, would become an Event of Default. Under such circumstances, the
        Buyer would have the right to acquire additional shares of Common Stock
        in the future only at such time as its ownership subsequently become
        less than the 9.9% limitation. For purposes of this Section, in
        determining the number of outstanding shares of Common Stock the Buyer
        may rely on the number of outstanding shares of Common Stock as
        reflected in (1) the Company's most recent Form 10-Q or Form 10-K, as
        the case may be, (2) a more recent public announcement by the Company or
        (3) any other written communication by the Company or its Transfer Agent
        setting forth the number of shares of Common Stock outstanding. Upon the
        reasonable written or oral request of the Buyer, the Company shall
        promptly confirm orally and in writing to the Buyer the number of shares
        of Common Stock then outstanding. In any case, the number of outstanding
        shares of Common Stock shall be determined after giving effect to any
        purchases under this Agreement by the Buyer since the date as of which
        such number of outstanding shares of Common Stock was reported. Except
        as otherwise set forth herein, for purposes of this Section 1(d)(i),
        beneficial ownership shall be determined in accordance with Section
        13(d) of the Securities Exchange Act of 1934, as amended.

               (ii) Company's Right to Suspend Purchases. The Company may, at
        any time, give written notice (a "Purchase Suspension Notice") to the
        Buyer suspending purchases of Purchase Shares by the Buyer under this
        Agreement. The Purchase Suspension Notice shall be effective only for
        purchases that have a Purchase Date later than one (1) Trading Day after
        receipt of the


                                      -3-
<PAGE>

        Purchase Suspension Notice by the Buyer. Any purchase by the Buyer that
        has a Purchase Date on or prior to the first (1st) Trading Day after
        receipt by the Buyer of a Purchase Suspension Notice from the Company
        must be honored by the Company as otherwise provided herein. Such
        purchase suspension shall continue in effect until a revocation in
        writing by the Company, at its sole discretion. So long as a Purchase
        Suspension Notice is in effect, the Buyer shall not be obligated to
        purchase any Purchase Shares from the Company under Section 1 of this
        Agreement.

               (iii) Purchase Price Floor. The Company shall not affect any
        sales under this Agreement and the Buyer shall not have the right nor
        the obligation to purchase any Purchase Shares under this Agreement on
        any Trading Day where the Purchase Price for any purchases of Purchase
        Shares would be less than the Floor Price.

        (e) Records of Purchases. The Buyer and the Company shall each maintain
records showing the remaining Available Amount at any given time and the dates
and Purchase Amounts for each purchase or shall use such other method,
reasonably satisfactory to the Buyer and the Company.

        (f) Taxes. The Company shall pay any and all transfer, stamp or similar
taxes that may be payable with respect to the issuance and delivery of any
shares of Common Stock to the Buyer made under this Agreement.

        (g) Compliance with Principal Market Rules. Notwithstanding any
provision hereof to the contrary, the Company shall not be required to effect
any issuance of Purchase Shares under this Agreement and the Buyer shall not
have the right to purchase any Purchase Shares under this Agreement on any
Trading Day where the Purchase Price for any purchase of Purchase Shares would
be less than the Base Price if such issuance would breach the Company's
obligations under the rules or regulations of the Principal Market. The "Base
Price" is $0.25 which is the greater of (x) the Market Price, and (y) the book
value per share of Common Stock as of September 30, 2002. "Market Price" shall
mean $0.25, the Closing Sale Price of the Common Stock on the Trading Day
immediately preceding the date of this Agreement. The Company hereby represents
and warrants to the Buyer that the book value per share of Common Stock as of
September 30, 2002 is $0.20. Notwithstanding any provision hereof to the
contrary, the Company shall not be required to issue any Purchase Shares under
this Agreement if such issuance would breach the Company's obligations under the
rules or regulations of the Principal Market.

        (h) Option for Second Tranche; Second Common Stock Purchase Agreement.
The Company may, in its sole discretion, at any time after the date hereof and
until 30 days after such date as the Available Amount is equal to $0 (the
"Second Tranche Expiration Date"), deliver an irrevocable written notice (the
"Second Tranche Notice") to the Buyer stating that the Company elects to enter
into an additional Common Stock Purchase Agreement (the "Second Common Stock
Purchase Agreement") with the Buyer for the purchase of Twelve Million Dollars
($12,000,000) of additional Common Stock. It is agreed and acknowledged by the
parties hereto that entering into the Second Common Stock Purchase Agreement
shall be at the option of the Company in its sole discretion until such time as
the Company shall have delivered the Second Tranche Notice to the Buyer. The
Buyer shall not be obligated to enter into the Second Common Stock Purchase
Agreement unless the Company has delivered the Second Tranche Notice prior to
the Second Tranche Expiration Date. The Second Common Stock Purchase Agreement
may not be entered into until the aggregate Available Amount under this
Agreement is fully used to buy Purchase Shares hereunder. Upon delivery of the
Second Tranche Notice to the Buyer prior to the Second Tranche Expiration Date,
the Buyer and the Company shall be obligated to enter into the Second Common
Stock Purchase Agreement no later than the date that is 10 Trading Days after
the Second Tranche Expiration Date. If the Buyer and the Company have not
entered into the Second Common Stock Purchase Agreement by the date that is 10
Trading Days after the Second Tranche


                                      -4-
<PAGE>

Expiration Date, the Buyer shall not be obligated to enter into such additional
Common Stock Purchase Agreement. The terms and conditions of the Second Common
Stock Purchase Agreement shall be in form and substance identical in all
respects to this Agreement, provided, however, that for purposes of the Second
Common Stock Purchase Agreement, this Section 1(h) shall be omitted.

        2.     BUYER'S REPRESENTATIONS AND WARRANTIES.

Buyer's right to rely on the Company's representations and warranties contained
in Section 3 below. The Buyer has sought such accounting, legal and tax advice
as it has considered necessary to make an informed investment decision with
respect to its acquisition of the Securities.

        (e) No Governmental Review. The Buyer understands that no United States
federal or state agency or any other government or governmental agency has

authorities passed upon or endorsed the merits of the offering of the
Securities.

the 1933 Act) may require compliance with some other exemption under the 1933
Act or the rules and regulations of the SEC thereunder; and (iii) neither the
Company nor any other person is under any obligation to register the Securities
under the 1933 Act or any state securities laws or to comply with the terms and
conditions of any exemption thereunder.

authorized, executed and delivered on behalf of the Buyer and is a valid and
binding agreement of the Buyer enforceable against the Buyer in accordance with
its terms, subject as to enforceability to general principles of equity and to

        (i) No Prior Short Selling. The Buyer represents and warrants to the
Company that at no time prior to the date of this Agreement has any of the
Buyer, its agents, representatives or affiliates engaged in or effected, in any
manner whatsoever, directly or indirectly, any (i) "short sale" (as such term is
defined in Rule 3b-3 of the 1934 Act) of the Common Stock or (ii) hedging
transaction, which establishes a net short position with respect to the Common
Stock.

        3.     REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

other similar equity interests) are corporations duly organized and validly

liquidation or similar laws relating to, or affecting generally, the enforcement

(subject to equitable adjustment for any reorganization, recapitalization,
non-cash dividend, stock split or other similar transaction) have been duly

accordance with Section 4(f) this Agreement. Upon issuance and payment therefor
in accordance with the terms and conditions of this Agreement, the Purchase
Shares shall be validly issued, fully paid and nonassessable and free from all
taxes, liens and charges with respect to the issue thereof, with the holders
being entitled to all rights accorded to a holder of Common Stock.

        (e) No Conflicts. Except as disclosed in Schedule 3(e), the execution,
delivery and performance of the Transaction Documents by the Company and the
consummation by the Company of the transactions contemplated hereby and thereby
(including, without limitation, the reservation for issuance and issuance of the
Purchase Shares) will not (i) result in a violation of the Articles of
Incorporation, any Certificate of Designations, Preferences and Rights of any
outstanding series of preferred stock of the Company or the By-laws or (ii)
conflict with, or constitute a default (or an event which with notice or lapse
of time or both would become a default) under, or give to others any rights of
termination, amendment, acceleration or cancellation of, any agreement,
indenture or instrument to which the Company or any of its Subsidiaries is a
party, or result in a violation of any law, rule, regulation, order, judgment or
decree (including federal and state securities laws and regulations and the
rules and regulations of the Principal Market applicable to the Company or any
of its Subsidiaries) or by which any property or asset of the Company or any of
its Subsidiaries is bound or affected, except in the case of conflicts, defaults
and violations under clause (ii), which could not reasonably be expected to
result in a Material Adverse Effect. Except as disclosed in Schedule 3(e),
neither the Company nor its Subsidiaries is in violation of any term of or in
default under its Articles of Incorporation, any Certificate of Designation,
Preferences and Rights of any outstanding series of preferred stock of the

Effect. The business of the Company and its Subsidiaries is not being conducted,
and shall not be conducted, in violation of any law, ordinance, regulation of
any governmental entity, except for possible violations, the sanctions for which
either individually or in the aggregate could not reasonably be expected to have
a Material Adverse Effect. Except as specifically contemplated by this Agreement
and as required under the 1933 Act or applicable state securities laws, the
Company is not required to obtain any consent, authorization or order of, or
make any filing or registration with, any court or governmental agency or any
regulatory or self-regulatory agency in order for it to execute, deliver or
perform any of its obligations under or contemplated by the Transaction
Documents in accordance with

        (f) SEC Documents; Financial Statements. Except as disclosed in Schedule
3(f), since July 1, 2001, the Company has timely filed all reports, schedules,
forms, statements and other documents required to be filed by it with the SEC
pursuant to the reporting requirements of the Securities Exchange Act of 1934,
as amended (the "1934 Act") (all of the foregoing filed prior to the date hereof
and all exhibits included therein and financial statements and schedules thereto
and documents incorporated by reference therein being hereinafter referred to as
the "SEC Documents"). As of their respective dates (except as they have been
correctly amended), the SEC Documents complied in all material respects with the
requirements of the 1934 Act and the rules and regulations of the SEC
promulgated thereunder applicable to the SEC Documents, and none of the SEC
Documents, at the time they were filed with the SEC (except as they may have
been properly amended), contained any untrue statement of a material fact or
omitted to state a material fact required to be stated therein or necessary in
order to make the statements therein, in light of the circumstances under which
they were made, not misleading. As of their respective dates (except as they
have been properly amended), the financial statements of the Company included in
the SEC Documents complied as to form in all material respects with applicable
accounting requirements and the published rules and regulations of the SEC with
respect thereto. Such financial statements have been prepared in accordance with
generally accepted accounting principles, consistently applied, during the
periods involved (except (i) as may be otherwise indicated in such financial
statements or the notes thereto or (ii) in the case of unaudited interim
statements, to the extent they may exclude footnotes or may be condensed or
summary statements) and fairly present in all material respects the financial
position of the Company as of the dates thereof and the results of its
operations and cash flows for the periods then ended (subject, in the case of
unaudited statements, to normal year-end audit adjustments). Except as listed in
Schedule 3(f), the Company has received no notices or correspondence from the
SEC since August 31, 2001. The SEC has not commenced any enforcement proceedings
against the Company or any of its subsidiaries.

        (g) Absence of Certain Changes. Except as disclosed in Schedule 3(g),
since June 30, 2002, there has been no material adverse change in the business,
properties, operations, financial condition or results of operations of the
Company or its Subsidiaries. The Company has not taken any steps, and does not
currently expect to take any steps, to seek protection pursuant to any
Bankruptcy Law nor does the Company or any of its Subsidiaries have any
knowledge or reason to believe that its creditors intend to initiate involuntary
bankruptcy or insolvency proceedings. The Company is financially solvent and is
generally able to pay its debts as they become due.

        (h) Absence of Litigation. There is no action, suit, proceeding, inquiry
or investigation before or by any court, public board, government agency,
self-regulatory organization or body pending or, to the knowledge of the Company
or any of its Subsidiaries, threatened against or affecting the Company, the
Common Stock or any of the Company's Subsidiaries or any of the Company's or the
Company's Subsidiaries' officers or directors in their capacities as such, which
could reasonably be expected to have a Material Adverse Effect. A description of
each action, suit, proceeding, inquiry or investigation before or by any court,
public board, government agency, self-regulatory organization or body which, as
of the date of this Agreement, is pending or threatened in writing against or
affecting the


                                      -9-
<PAGE>

Company, the Common Stock or any of the Company's Subsidiaries or any of the
Company's or the Company's Subsidiaries' officers or directors in their
capacities as such, is set forth in Schedule 3(h).

        (i) Acknowledgment Regarding Buyer's Status. The Company acknowledges
and agrees that the Buyer is acting solely in the capacity of arm's length
purchaser with respect to the Transaction Documents and the transactions
contemplated hereby and thereby. The Company further acknowledges that the Buyer
is not acting as a financial advisor or fiduciary of the Company (or in any
similar capacity) with respect to the Transaction Documents and the transactions
contemplated hereby and thereby and any advice given by the Buyer or any of its
representatives or agents in connection with the Transaction Documents and the
transactions contemplated hereby and thereby is merely incidental to the Buyer's
purchase of the Securities. The Company further represents to the Buyer that the
Company's decision to enter into the Transaction Documents has been based solely
on the independent evaluation by the Company and its representatives and
advisors.

        (j) No General Solicitation. Neither the Company, nor any of its
affiliates, nor any person acting on its or their behalf, has engaged in any
form of general solicitation or general advertising (within the meaning of
Regulation D under the 1933 Act) in connection with the offer or sale of the
Securities.

         (k) Dilutive Effect. The Company understands and acknowledges that the
number of Purchase Shares purchasable under this Agreement is not fixed and will
vary depending on the Purchase Price at which such shares are purchased. The
Company further acknowledges that its obligation to issue Purchase Shares under
this Agreement in accordance with the terms and conditions hereof is absolute
and unconditional regardless of the dilutive effect that such issuance may have
on the ownership interests of other shareholders of the Company.

        (l) Intellectual Property Rights. The Company and its Subsidiaries own
or possess adequate rights or licenses to use all material trademarks, trade
names, service marks, service mark registrations, service names, patents, patent
rights, copyrights, inventions, licenses, approvals, governmental
authorizations, trade secrets and rights necessary to conduct their respective
businesses as now conducted. Except as set forth on Schedule 3(l), none of the
Company's material trademarks, trade names, service marks, service mark
registrations, service names, patents, patent rights, copyrights, inventions,
licenses, approvals, government authorizations, trade secrets or other
intellectual property rights have expired or terminated, or, by the terms and
conditions thereof, could expire or terminate within two years from the date of
this Agreement. The Company and its Subsidiaries do not have any knowledge of
any infringement by the Company or its Subsidiaries of any material trademark,
trade name rights, patents, patent rights, copyrights, inventions, licenses,
service names, service marks, service mark registrations, trade secret or other
similar rights of others, or of any such development of similar or identical
trade secrets or technical information by others and, except as set forth on
Schedule 3(l), there is no claim, action or proceeding being made or brought
against, or to the Company's knowledge, being threatened against, the Company or
its Subsidiaries regarding trademark, trade name, patents, patent rights,
invention, copyright, license, service names, service marks, service mark
registrations, trade secret or other infringement, which could reasonably be
expected to have a Material Adverse Effect.

        (m) Environmental Laws. The Company and its Subsidiaries (i) are in
compliance with any and all applicable foreign, federal, state and local laws
and regulations relating to the protection of human health and safety, the
environment or hazardous or toxic substances or wastes, pollutants or
contaminants ("Environmental Laws"), (ii) have received all permits, licenses or
other approvals required of them under applicable Environmental Laws to conduct
their respective businesses and (iii) are in compliance with all terms and
conditions of any such permit, license or approval, except where, in each


                                      -10-
<PAGE>

of the three foregoing clauses, the failure to so comply could not reasonably be
expected to have, individually or in the aggregate, a Material Adverse Effect.

        (n) Title. The Company and its Subsidiaries have good and marketable
title in fee simple to all real property and good and marketable title to all
personal property owned by them which is material to the business of the Company
and its Subsidiaries, in each case free and clear of all liens, encumbrances and
defects except such as are described in Schedule 3(n) or such as do not
materially affect the value of such property and do not interfere with the use
made and proposed to be made of such property by the Company and any of its
Subsidiaries. Any real property and facilities held under lease by the Company
and any of its Subsidiaries are held by them under valid, subsisting and
enforceable leases with such exceptions as are not material and do not interfere
with the use made and proposed to be made of such property and buildings by the
Company and its Subsidiaries.

        (o) Insurance. The Company and each of its Subsidiaries are insured by
insurers of recognized financial responsibility against such losses and risks
and in such amounts as management of the Company believes to be prudent and
customary in the businesses in which the Company and its Subsidiaries are
engaged. Neither the Company nor any such Subsidiary has been refused any
insurance coverage sought or applied for and neither the Company nor any such
Subsidiary has any reason to believe that it will not be able to renew its
existing insurance coverage as and when such coverage expires or to obtain
similar coverage from similar insurers as may be necessary to continue its
business at a cost that would not materially and adversely affect the condition,
financial or otherwise, or the earnings, business or operations of the Company
and its Subsidiaries, taken as a whole.

        (p) Regulatory Permits. The Company and its Subsidiaries possess all
material certificates, authorizations and permits issued by the appropriate
federal, state or foreign regulatory authorities necessary to conduct their
respective businesses, and neither the Company nor any such Subsidiary has
received any notice of proceedings relating to the revocation or modification of
any such certificate, authorization or permit.

        (q) Tax Status. The Company and each of its Subsidiaries has made or
filed all federal and state income and all other material tax returns, reports
and declarations required by any jurisdiction to which it is subject (unless and
only to the extent that the Company and each of its Subsidiaries has set aside
on its books provisions reasonably adequate for the payment of all unpaid and
unreported taxes) and has paid all taxes and other governmental assessments and
charges that are material in amount, shown or determined to be due on such
returns, reports and declarations, except those being contested in good faith
and has set aside on its books provision reasonably adequate for the payment of
all taxes for periods subsequent to the periods to which such returns, reports
or declarations apply. There are no unpaid taxes in any material amount claimed
to be due by the taxing authority of any jurisdiction, and the officers of the
Company know of no basis for any such claim.

        (r) Transactions With Affiliates. Except as set forth on Schedule 3(r)
and other than the grant or exercise of stock options disclosed on Schedule
3(c), none of the officers, directors, or employees of the Company is presently
a party to any transaction with the Company or any of its Subsidiaries (other
than for services as employees, officers and directors), including any contract,
agreement or other arrangement providing for the furnishing of services to or
by, providing for rental of real or personal property to or from, or otherwise
requiring payments to or from any officer, director or such employee or, to the
knowledge of the Company, any corporation, partnership, trust or other entity in
which any officer, director, or any such employee has an interest or is an
officer, director, trustee or partner.


                                      -11-
<PAGE>

        (s) Application of Takeover Protections. The Company and its board of
directors have taken or will take prior to the Commencement Date all necessary
action, if any, in order to render inapplicable any control share acquisition,
business combination, poison pill (including any distribution under a rights
agreement) or other similar anti-takeover provision under the Articles of
Incorporation or the laws of the state of its incorporation which is or could
become applicable to the Buyer as a result of the transactions contemplated by
this Agreement, including, without limitation, the Company's issuance of the
Securities and the Buyer's ownership of the Securities.

        (t) Foreign Corrupt Practices. Neither the Company, nor any of its
Subsidiaries, nor any director, officer, agent, employee or other person acting
on behalf of the Company or any of its Subsidiaries has, in the course of its
actions for, or on behalf of, the Company, used any corporate funds for any
unlawful contribution, gift, entertainment or other unlawful expenses relating
to political activity; made any direct or indirect unlawful payment to any
foreign or domestic government official or employee from corporate funds;
violated or is in violation of any provision of the U.S. Foreign Corrupt
Practices Act of 1977, as amended; or made any unlawful bribe, rebate, payoff,
influence payment, kickback or other unlawful payment to any foreign or domestic
government official or employee.

        4.     COVENANTS.

        (a) Filing of Registration Statement. The Company shall, on or before
October 31, 2002, file a new registration statement covering the sale of the
Commitment Shares and at least 10,000,000 Purchase Shares. The Buyer and its
counsel shall have a reasonable opportunity to review and comment upon such
registration statement or amendment to such registration statement and any
related prospectus prior to its filing with the SEC. Buyer shall furnish all
information reasonably requested by the Company for inclusion therein. The
Company shall use its best efforts to have such registration statement or
amendment declared effective by the SEC at the earliest possible date.

        (b) Blue Sky. The Company shall take such action, if any, as is
reasonably necessary in order to obtain an exemption for or to qualify (i) the
initial sale of the Commitment Shares and any Purchase Shares to the Buyer under
this Agreement and (ii) any subsequent resale of the Commitment Shares and any
Purchase Shares by the Buyer, in each case, under applicable securities or "Blue
Sky" laws of the states of the United States in such states as is reasonably
requested by the Buyer from time to time, and shall provide evidence of any such
action so taken to the Buyer.

        (c) No Variable Priced Financing. Other than pursuant to this Agreement,
the Company agrees that beginning on the date of this Agreement and ending on
the date of termination of this Agreement (as provided in Section 11(k) hereof),
neither the Company nor any of its Subsidiaries shall, without the prior written
consent of the Buyer, contract for any equity financing (including any debt
financing with an equity component) or issue any equity securities of the
Company or any Subsidiary or securities convertible or exchangeable into or for
equity securities of the Company or any Subsidiary (including debt securities
with an equity component) which, in any case (i) are convertible into or
exchangeable for an indeterminate number of shares of common stock, (ii) are
convertible into or exchangeable for Common Stock at a price which varies with
the market price of the Common Stock, (iii) directly or indirectly provide for
any "re-set" or adjustment of the purchase price, conversion rate or exercise
price after the issuance of the security, or (iv) contain any "make-whole"
provision based upon, directly or indirectly, the market price of the Common
Stock after the issuance of the security, in each case, other than reasonable
and customary anti-dilution adjustments for issuance of shares of Common Stock
at a price which is below the market price of the Common Stock.


                                      -12-
<PAGE>

        (d) Listing. The Company shall promptly secure the listing of 10,000,000
Purchase Shares and the Commitment Shares upon each national securities exchange
and automated quotation system, if any, upon which shares of Common Stock are
then listed (subject to official notice of issuance) and shall maintain, so long
as any other shares of Common Stock shall be so listed, such listing of all such
securities from time to time issuable under the terms of the Transaction
Documents. The Company shall maintain the Common Stock's authorization for
quotation on the Principal Market. Neither the Company nor any of its
Subsidiaries shall take any action that would be reasonably expected to result
in the delisting or suspension of the Common Stock on the Principal Market. The
Company shall promptly, and in no event later than the following Trading Day,
provide to the Buyer copies of any notices it receives from the Principal Market
regarding the continued eligibility of the Common Stock for listing on such
automated quotation system or securities exchange. The Company shall pay all
fees and expenses in connection with satisfying its obligations under this
Section.

        (e) Limitation on Short Sales and Hedging Transactions. The Buyer agrees
that beginning on the date of this Agreement and ending on the date of
termination of this Agreement as provided in Section 11(k), the Buyer and its
agents, representatives and affiliates shall not in any manner whatsoever enter
into or effect, directly or indirectly, any (i) "short sale" (as such term is
defined in Rule 3b-3 of the 1934 Act) of the Common Stock or (ii) hedging
transaction, which establishes a net short position with respect to the Common
Stock.

        (f) Issuance of Commitment Shares; Limitation on Sales of Commitment
Shares. Immediately upon the execution of this Agreement, the Company shall
issue to the Buyer 970,350 shares of Common Stock (the "Initial Commitment
Shares"). In connection with each purchase of Purchase Shares hereunder, the
Company agrees to issue to the Buyer a number of shares of Common Stock (the
"Additional Commitment Shares" and together with the Initial Commitment Shares,
the "Commitment Shares") equal to the product of (x) 970,350 and (y) the
Purchase Amount Fraction. The "Purchase Amount Fraction" shall mean a fraction,
the numerator of which is the Purchase Amount purchased by the Buyer with
respect to such purchase of Purchase Shares and the denominator of which is
Twelve Million Dollars ($12,000,000). The Additional Commitment Shares shall be
equitably adjusted for any reorganization, recapitalization, non-cash dividend,
stock split or other similar transaction. The Initial Commitment Shares shall be
issued in certificated form and (subject to Section 5 hereof) shall bear the
following restrictive legend:

        "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
        UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE
        SECURITIES LAWS. THE SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT AND
        MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED IN THE
        ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER
        THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES
        LAWS, OR AN OPINION OF COUNSEL, IN A FORM REASONABLY ACCEPTABLE TO THE
        COMPANY, THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT OR APPLICABLE
        STATE SECURITIES LAWS OR UNLESS SOLD PURSUANT TO RULE 144 UNDER SAID
        ACT."

        The Buyer agrees that the Buyer shall not transfer or sell the
Commitment Shares until the earlier of 480 Trading Days (24 Monthly Periods)
from the date hereof or date on which this Agreement has been terminated,
provided, however, that such restrictions shall not apply: (i) in connection
with any transfers to or among affiliates (as defined in the 1934 Act), (ii) in
connection with any pledge in connection with a bona fide loan or margin
account, or (iii) if an Event of Default has occurred, or any


                                      -13-
<PAGE>

event which, after notice and/or lapse of time, would become an Event of
Default, including any failure by the Company to timely issue Purchase Shares
under this Agreement. Notwithstanding the forgoing, the Buyer may transfer
Commitment Shares to a third party in order to settle a sale made by the Buyer
where the Buyer reasonably expects the Company to deliver Purchase Shares to the
Buyer under this Agreement so long as the Buyer maintains ownership of the same
overall number of shares of Common Stock by "replacing" the Commitment Shares so
transferred with Purchase Shares when the Purchase Shares are actually issued by
the Company to the Buyer.

        (g) Due Diligence. The Buyer shall have the right, from time to time as
the Buyer may reasonably deem appropriate, to perform reasonable due diligence
on the Company during normal business hours. The Company and its officers and
employees shall reasonably cooperate with the Buyer in connection with any
reasonable request by the Buyer related to the Buyer's due diligence of the
Company. Each party hereto agrees not to disclose any Confidential Information
of the other party to any third party and shall not use the Confidential
Information for any purpose other than in connection with, or in furtherance of,
the transactions contemplated hereby. Each party hereto acknowledges that the
Confidential Information shall remain the property of the disclosing party and
agrees that it shall take all reasonable measures to protect the secrecy of any
Confidential Information disclosed by the other party.

        5.     TRANSFER AGENT INSTRUCTIONS.

        Immediately upon the execution of this Agreement, the Company shall
deliver to the Transfer Agent a letter in the form as set forth as Exhibit F
attached hereto with respect to the issuance of the Initial Commitment Shares.
On the Commencement Date, the Company shall cause any restrictive legend on the
Initial Commitment Shares to be removed (upon delivery of the certificate
evidencing the Initial Commitment Shares to the Company or its Transfer Agent)
and all of the Purchase Shares and Additional Commitment Shares, to be issued
under this Agreement shall be issued without any restrictive legend. The Company
shall issue irrevocable instructions to the Transfer Agent, and any subsequent
transfer agent, to issue Purchase Shares in the name of the Buyer for the
Purchase Shares (the "Irrevocable Transfer Agent Instructions"). The Company
warrants to the Buyer that no instruction other than the Irrevocable Transfer
Agent Instructions referred to in this Section 5, will be given by the Company
to the Transfer Agent with respect to the Purchase Shares and that the
Commitment Shares and the Purchase Shares shall otherwise be freely transferable
on the books and records of the Company as and to the extent provided in this
Agreement and the Registration Rights Agreement subject to the provisions of
Section 4(f) in the case of the Commitment Shares.

        6.     CONDITIONS TO THE COMPANY'S OBLIGATION TO COMMENCE
               SALES OF SHARES OF COMMON STOCK.

        The obligation of the Company hereunder to commence sales of the
Purchase Shares is subject to the satisfaction of each of the following
conditions on or before the Commencement Date (the date that sales begin) and
once such conditions have been initially satisfied, there shall not be any
ongoing obligation to satisfy such conditions after the Commencement has
occurred; provided that these conditions are for the Company's sole benefit and
may be waived by the Company at any time in its sole discretion by providing the
Buyer with prior written notice thereof:

        (c) The representations and warranties of the Buyer shall be true and
correct in all material respects as of the date when made and as of the
Commencement Date as though made at that time (except for representations and
warranties that speak as of a specific date), and the Buyer shall have

agreements and conditions required by this Agreement to be performed, satisfied
or complied with by the Buyer at or prior to the Commencement Date.

               (iii) In the event that the Commencement shall not have occurred
        on or before February 28, 2003, due to the failure to satisfy the

        as provided herein, without any action or notice on the part of any
        party.

               (vii) By the Buyer at any time in the event of the delisting of

any liability, loss or expense (including, without limitation, attorneys' fees
and out of pocket expenses) arising in connection with any such claim.

Buyer's remedies provided in this Agreement shall be cumulative and in addition
to all other remedies available to the Buyer under this Agreement, at law or in
equity (including a decree of specific performance and/or other injunctive
relief), no remedy of the Buyer contained herein shall be deemed a waiver of
compliance with the provisions giving rise to such remedy and nothing herein
shall limit the Buyer's right to pursue actual damages for any failure by the
Company to comply with the terms of this Agreement. The Company acknowledges
that a breach by it of its obligations hereunder will cause irreparable harm to
the Buyer and that the remedy at law for any such breach may be inadequate. The
Company therefore agrees that, in the event of any such breach or threatened
breach, the Buyer shall be entitled, in addition to all other available
remedies, to an injunction restraining any breach, without the necessity of
showing economic loss and without any bond or other security being required.

        (o) Changes to the Terms of this Agreement. This Agreement and any
provision hereof may only be amended by an instrument in writing signed by the
Company and the Buyer. The term


                                      -24-

"Agreement" and all reference thereto, as used throughout this instrument, shall
mean this instrument as originally executed, or if later amended or
supplemented, then as so amended or supplemented.

        (p) Enforcement Costs. If: (i) this Agreement is placed by the Buyer in
the hands of an attorney for enforcement or is enforced by the Buyer through any
legal proceeding; or (ii) an attorney is retained to represent the Buyer in any
bankruptcy, reorganization, receivership or other proceedings affecting
creditors' rights and involving a claim under this Agreement; then the Company
shall pay to the Buyer, as incurred by the Buyer, all reasonable costs and
expenses including attorneys' fees incurred in connection therewith, in addition
to all other amounts due hereunder.

        (q) Failure or Indulgence Not Waiver. No failure or delay in the
exercise of any power, right or privilege hereunder shall operate as a waiver
thereof, nor shall any single or partial exercise of any such power, right or
privilege preclude other or further exercise thereof or of any other right,
power or privilege.
