product and/or service by the fraction A over A&#043;B, in which A is the gross selling price of the
Product portion of the end-user product and/or service when such Product is sold separately during
the applicable accounting period in which the sales of the end-user product were made, and B is the

which the Net Sales are being calculated. In the event that, in any country or countries, no
separate sale of either such above-designated Product or such above designated elements of the
end-user product and/or service are made during the accounting period in which the sale was made or
if gross retail selling price for an active functional element, component or service, as the case
may be, cannot be determined for an accounting period, Net Sales allocable to the Product in each
such country shall be determined by mutual agreement reached in good faith by the Parties prior to
the end of the accounting period in question based on
an equitable method of determining same that takes into account, on a country by country basis,
variations in potency, the relative contribution of each active agent, component or service, as the

additional Collaboration Cell Lines. The foregoing is subject to the additional proviso that
Athersys shall not be required to provide to BMS more than fifteen (15)&nbsp;Collaboration Cell Lines
per year commencing on the Anniversary Date. Notwithstanding any provision of this Section&nbsp;2.5 to
the contrary, the Parties will meet on or about each subsequent Anniversary Date to discuss in good

in accordance with the scientific and business objectives of the Parties. In the event the Parties
determine that such continuation is not reasonably within Athersys&#146;s business objectives, any
different terms the Parties may negotiate with respect to any continued collaboration hereunder
shall be reasonably consistent with the terms on which Athersys is then performing, or reasonably
proposing to perform, services of similar character and quantity for Third Parties.

therefrom), and thus which do not fall within the definition of Candidate Compounds. If BMS
decides that it wishes to obtain a license to make such use of an Accepted Cell Line, BMS shall so
notify Athersys at any time during the term of the License with respect to such Accepted Cell Line.
Following Athersys&#146; receipt of such notice, the Parties shall negotiate, diligently and in good

license. Such negotiations shall continue for a period of 120&nbsp;days (or such longer period as the

</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Promptly after the Effective Date the Parties shall agree upon an initial list of specific proteins
with respect to which Athersys will create RAGE libraries and promptly thereafter screen and
isolate Athersys Cell Lines expressing such proteins. Such list shall be deemed to constitute a
part of this Exhibit&nbsp;A. Such list may be supplemented from time to time by mutual agreement of the
Parties or by designation of additional specific proteins by BMS and acceptance of such proteins by
Athersys, as provided in Section&nbsp;2.1 (and Section&nbsp;2.5, to the extent applicable) and in accordance
with the procedure provided below.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">From time to time, BMS may nominate specific proteins for consideration by Athersys under Section
2.1 (and Section&nbsp;2.5, to the extent applicable), for use in constructing a Collaboration Cell Line
using its RAGE technology and other Athersys Know-How. Any such Collaboration Cell Line shall
conform to the general specifications set forth in Exhibit&nbsp;B and to any other specific requirements
agreed to by the Parties.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Athersys shall have the right, before accepting such request of a particular protein by BMS
hereunder, to review and approve the technical and intellectual property feasibility of
constructing the requested Collaboration Cell Line. If requested by Athersys, BMS shall promptly
provide to Athersys the relevant technical requirements of BMS for the requested Collaboration Cell
Line. Athersys shall make its determination of technical feasibility, intellectual property
analysis and/or conflict with preexisting exclusive research obligations to Third Parties or
preexisting internal research programs for which screening has commenced prior to receiving notice
(a &#147;Pre-existing Program&#148;), within thirty (30)&nbsp;days of the request by BMS. If Athersys believes
that the project is not constrained by any of these considerations or fails to provide any such
notice within such thirty (30)&nbsp;day period, then the nominated protein (and corresponding
Collaboration Cell Line) shall be deemed to be added to this Exhibit&nbsp;A. If Athersys believes the
project is constrained by any of such considerations and provides such notice within such thirty
(30)&nbsp;day period, such protein and cell line shall not be added to Exhibit&nbsp;A; provided that Athersys
shall provide to BMS all pertinent information Controlled by Athersys regarding the basis for its
rejection of such request. In that event, BMS shall be entitled to nominate another protein (with
the foregoing process being repeated), until a protein nominated by BMS hereunder is accepted by
Athersys. For purposes of calculating the maximum number of cell lines permitted under this
Agreement, any substitute request made by BMS shall be deemed to have been made as of the date of
the original request.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">In addition, in the event Athersys commences a Pre-existing Program with respect to a target
(either internally or with a Third Party), and BMS subsequently proposes such target under Section
2.1, Athersys shall promptly inform BMS of such program and request that BMS propose a substitute
target. In such event, Athersys shall, upon BMS&#146; request, provide, on a confidential basis, a
reasonable demonstration of such commencement and prosecution of any such Pre-existing Program for
a given target prior to the date of BMS&#146; proposal of such target under Section&nbsp;2.1.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">As used in this Exhibit&nbsp;C, the phrase &#147;Initiation of first Phase III clinical study&#148; shall be
deemed to include, if a party conducts a Phase II/III study on a Candidate Compound, the point
during such Phase II/III clinical trial when the party conducting the trial has the regulatory
approval to proceed with such trial as a pivotal trial.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">BMS shall promptly notify Athersys of the first occurrence of any milestone with respect to each
Candidate Compound. Milestone payments shall be made only once with respect to any given Candidate
Compound, regardless of the number of indications sought (or approvals obtained) with respect to
such Candidate Compound, whether alone or in combination with other compounds or products, and
regardless of any new dosage strengths, preparations or forms of administration for such Candidate
Compound.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">If BMS develops as a back-up compound that inhibits or otherwise modulates the activity of a
particular molecular target of a Candidate Compound on which BMS is already making milestone
payments, then BMS may conduct clinical development on such back-up or follow-on compounds and
shall not be obligated to make any milestone payments with respect to any such back-up or follow-on
compound, except as otherwise provided below. In the event that a particular Candidate Compound is
dropped from active clinical development work or marketing for safety or efficacy reasons and is
specifically replaced with a different compound targeting the same molecular target as such dropped
Candidate Compound, such new compound shall be deemed a &#147;Replacement Compound.&#148; BMS shall not be
obligated to make milestone payments that were earlier made with respect to a dropped Candidate
Compound and replaced by a Replacement Compound, but, subject to the preceding paragraph, BMS shall
pay all milestone payments for milestone events achieved by such Replacement Compound that had not
been achieved by such dropped Candidate Compound.
