(b) Authorization and Binding Nature. The execution, delivery and performance by
the Company of the Agreement and the issuance and delivery of the Shares has
been duly authorized by all requisite corporate action on the part of the
Company. The Agreement constitutes the valid and legally binding obligation of
the Company, enforceable against the Company in accordance with its terms,
except as enforceability may be limited by securities laws, bankruptcy,

Incorporation or Bylaws of the Company; (ii) violate or conflict with any
judgment, decree, order or award of any court, governmental body or arbitrator
applicable to the Company; or (iii) violate, conflict with or cause a default
under any mortgage, indenture, lease, contract or other agreement or instrument,
permit, or license to which the Company is subject except, in the case of this
clause (iii), any violation, conflict or default that would not have a Material
Adverse Effect. For purposes of this Agreement, “Material Adverse Effect” shall
mean, with respect to an entity, any state of facts, events, change or effect,
either individually or in the aggregate, that has had, or would reasonably be
expected to have, a material adverse effect on the business, properties,

registration, qualification, designation, declaration or filing with, any
federal, state or local governmental authority is required on the part of the
Company in order to enable the Company to execute, deliver and perform its

the Company to issue any shares of its capital stock or any securities
convertible into or evidencing the right to purchase or subscribe for any shares
of such stock, and there are no agreements or understandings with respect to the
voting, sale or transfer of any shares of capital stock of the Company to which
the Company is a party. When issued, sold and delivered against payment
therefore in accordance with the provisions of this Agreement, the Shares will
be duly authorized, validly issued, fully paid and nonassessable, and will be
free of restrictions on transfer other than restrictions under this Agreement

Price at Closing, Purchaser shall have good and marketable title to the Shares.

 

(f) SEC Reports. The Company has timely filed all reports, schedules and other
documents required to be filed by the Company with the Securities and Exchange
Commission under the Securities Exchange Act of 1934, as amended (the “Exchange
Act”) including but not limited to any certifications required to be made under
the Sarbanes-Oxley Act of 2002 or any rules promulgated thereunder. The
Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2002
(the “2002 Form 10-K”) and all reports filed by the Company under Section 13 of
the Exchange Act with the Securities and Exchange Commission (“SEC”), since
December 31, 2002 (together with the 2002 Form 10-K, the “Reports”) have
complied in all material respects with the applicable requirements of the
Exchange Act, and the respective rules and regulations thereunder when filed. As
of their respective dates, the Reports did not contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading.

 

(g) Governmental Permits. The Company owns, possesses or has obtained all
licenses, permits, certificates, consents, orders, approvals and other
authorizations from, and has made all declarations and filings with, all
federal, state, local and other governmental authorities (including foreign
regulatory agencies), all self-regulatory organizations and all courts and other
tribunals, domestic or foreign, necessary to operate its properties and to carry
on its business as conducted as of the date hereof, except where the failure so
to own, possess, obtain or make would not have a Material Adverse Effect. The
Company has not received any actual notice of any proceeding relating to
revocation or modification of any such license, permit, certificate, consent,
order, approval or other authorization. To its knowledge, the Company is in
compliance with all laws and regulations relating to the conduct of its business
as conducted as of the date hereof, except where noncompliance would not have a
Material Adverse Effect.

 

(h) Taxes. The Company has filed all tax returns required to be filed by or on
behalf of the Company, except to the extent that a failure to file would not
have a Material Adverse Effect. All such filings are true and correct in all
material respects, and the Company is not in default in the payment of any
taxes, including penalties and interest, assessments, fees and other charges
shown thereon due or otherwise assessed other than those being contested in good
faith and for which adequate reserves have been provided, those currently
payable without which were payable pursuant to said returns or any assessments
with respect thereto and those defaults which would not have a Material Adverse
Effect.

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

(i) Intellectual Property. The Company, to its knowledge, owns or is licensed to
use all patents, patent applications, inventions, trademarks, trade names,
applications for registration of trademarks, service marks, service mark
applications, copyrights, know-how, manufacturing processes, formulae, trade
secrets, licenses and rights in any thereof and any other intangible property
and assets that are material to the business of the Company as now conducted and
as, on the date hereof, proposed to be conducted (the “Proprietary Rights”), or
is seeking, or will seek, to obtain rights to use such Proprietary Rights that
are material to the business of the Company, on the date hereof, as proposed to
be conducted. The Company does not have any knowledge of, and the Company has
not given or received any notice of, any pending conflicts with or infringement
of the rights of others with respect to any Proprietary Rights, or with respect
to any license of Proprietary Rights, that are material to the business of the
Company. No action, suit, arbitration, or legal, administrative or other
proceeding, or investigation is pending, or, to the Company’s knowledge,
threatened, which involves any Proprietary Rights, nor, to the Company’s
knowledge, is there any reasonable basis therefore.

 

(j) No Material Adverse Change. Except as described or referred to in the
Reports, since September 30, 2003 there has not been any event, change or
development which would have a Material Adverse Effect, other than a state of
facts, events, change or effect attributable to changes in general economic or
market conditions affecting the life science and pharmaceutical industries.

 

(k) Litigation. There is no action, suit or proceeding before or by any court or
governmental agency or body, domestic or foreign, now pending, or, to the
knowledge of the Company, threatened against or affecting the Company which
could have a Material Adverse Effect.

 

(l) NASDAQ National Market Designation. The Company’s Common Stock is currently
included in the NASDAQ National Market of the NASDAQ Stock Market and, as of the

3. Representations and Warranties of the Purchaser. The Purchaser represents and
warrants to the Company that the statements contained in this Section 3 are true
and correct as of the date of this Agreement.

 

(a) Investment. The Purchaser is acquiring the Shares for its own account for
investment, not for resale to any other person and not with a view to or in
connection with any resale or distribution. The Purchaser understands that the
Shares have not been registered under the securities laws of the United States
or any other jurisdiction and cannot be transferred or resold except as
permitted pursuant to a valid registration statement or an applicable exemption
from registration. The Purchaser understands that an investment in the Company
involves significant risks. The Purchaser acknowledges that, except for the
registration and other rights contemplated herein, there can be no assurance
that there will be any market for the Common Stock in the foreseeable future and
that, as a result, the Purchaser must be prepared to bear the economic risk of
its investment for an indefinite period of time. The Purchaser understands that
the certificate representing the Shares shall bear a legend substantially in the
following form (it being agreed that the opinion of counsel referred to below
shall be deemed to mean the inside or outside counsel of Purchaser, as
designated by Purchaser):

 

- 4 -

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

“The securities represented by this certificate have not been

registered under the Securities Act of 1933, as amended, and may

not be sold, exchanged, transferred, pledged, hypothecated or

otherwise disposed of unless and until such securities are

registered under such Act or an opinion of counsel reasonably

satisfactory to the issuer is obtained to the effect that such

registration is not required.”

 

The foregoing legend shall be removed and the Company shall issue a certificate
without such legend to the holder of any Shares upon which it is stamped, if,
unless otherwise required by state securities laws, (i) the sale of such Shares
is registered under the Securities Act of 1933, as amended (the “Securities
Act”), or (ii) the Shares become eligible for resale pursuant to Rule 144 of the
Securities Act.

 

(b) Authorization and Binding Nature. The execution, delivery and performance by
the Purchaser of the Agreement has been duly authorized by all requisite
corporate action on the part of the Purchaser. The Agreement constitutes the
valid and legally binding obligation of the Purchaser, enforceable against the
Purchaser in accordance with its terms, except as enforceability may be limited
by securities laws, bankruptcy, insolvency, fraudulent transfer, reorganization,
moratorium or other similar laws relating to or affecting the rights of
creditors generally and by equitable principles, including those limiting the
availability of specific performance, injunctive relief and other equitable
remedies.

 

(c) Non-Contravention. The execution, delivery and performance by the Purchaser
of the Agreement will not, with or without the giving of notice or the passage
of time or both, (i) violate or conflict with the provisions of the Certificate
of Incorporation or Bylaws of the Purchaser, (ii) violate or conflict with any
judgment, decree, order or award of any court, governmental body or arbitrator
applicable to the Purchaser or (iii) violate, conflict with or cause a default
under any mortgage, indenture, lease, contract or other agreement or instrument,
permit, or license to which the Purchaser is subject other than any violation,
conflict or default which would not have a Material Adverse Effect.

 

(d) Access to Information. The Purchaser has substantial knowledge and
experience in making investment decisions of this type and is capable of
evaluating the merits and risks of its investment in the Company. The Company
has made available to the Purchaser all documents and other information
necessary for the Purchaser to evaluate the merits and risks of its investment
in the Company.

5. Registration Rights.

 

5.1 Registration of the Shares.

 

(a) At any time after the Closing Date, so long as the Company is then eligible
to file a registration statement on Form S-3 (or any successor form relating to
secondary offerings), the Purchaser may request, in writing, that the Company
effect the registration on Form S-3 (or such successor form) of the Shares;
provided, however, that pursuant to the terms of Section 6 below, Purchaser
shall not have the right to sell or otherwise dispose of the Shares on or before
the date which is 90 days after the Closing Date, except as provided in such
Section. Upon receipt of such request for registration pursuant to this Section
5.1, the Company shall promptly file with the SEC a registration statement on
Form S-3 (or any successor form) covering the resale to the public by the
Purchaser of the Shares. The Company shall use commercially reasonable efforts
to cause the registration statement to be declared effective by the SEC as soon
as practicable. The Company shall use commercially reasonable efforts to file
such amendments and supplements to such registration statement to cause it
remain effective until the date two years after the date hereof or such earlier
time as all of the Shares covered by the registration statement have been sold
pursuant thereto. The Company will not be required to effect more than one
registration pursuant to this Section 5.1(a). The Company may, by written notice
to the Purchaser, delay the filing or effectiveness of a registration statement
under this Section 5.1(a) for a period of not more than 60 days from the date of
such request if the Board of Directors of the Company makes a good faith
determination that filing at such time would be materially detrimental to the
Company. Such right to delay a request shall not be exercised by the Company
more than twice in any 12-month period.

 

(b) If, at any time, the Company proposes to register any of its Common Stock on
a registration statement filed with the SEC for an underwritten public offering
and sale of Common Stock for cash (an “Underwritten Offering”) (other than a
registration statement on Form S-8 or Form S-4, or their successors, a
“universal shelf” registration statement pursuant to Rule 415 under the
Securities Act, or any other form for a limited purpose), then the Company shall
promptly give the Purchaser written notice of such proposed Underwritten
Offering. Upon written request of the Purchaser given within fourteen (14) days
after receipt of any such notice by the Company, the Company shall use its
commercially reasonable efforts to cause to be registered under the Securities
Act all of the Shares that the Purchaser has requested be registered; provided
that the Company shall have the right to postpone or withdraw any registration
effected pursuant to this Section 5.1(b) without any obligation to the
Purchaser.

 

(c) In connection with any Underwritten Offering under Section 5.1(b), if the
managing underwriters advise the Company of their reasonable opinion that
marketing factors require a limitation in the number of shares to be included by
persons other

 

- 7 -

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

than the Company the shares held by the Purchaser and any other holders of
securities of the Company who are entitled, by contract with the Company, to
have securities included in an Underwritten Offering (the “Other Holders”) shall
be excluded from such registration statement and underwriting to the extent
deemed advisable by the managing underwriters; provided that in no case shall
the Shares along with the shares of other Holders be reduced to less than 10% of
the proceeds of such Underwritten Offering. If a reduction in the number of
shares to be included by the Purchaser and Other Holders is required, the number
of shares that may be included in such Underwritten Offering shall be allocated
among the Purchaser and such Other Holders, as nearly as practicable, to the
respective number of shares of Common Stock held by them on the date the Company
gives notice as specified above. If the Purchaser or any Other Holder would thus
be entitled to include more shares than such holder requested to be registered,
the excess shall be allocated among the Purchaser and Other Holders in the
manner described in the preceding sentence.

 

(d) In the event the Purchaser intends to include its shares in an Underwritten
Offering, such right shall be conditioned upon the Purchaser’s participation in
such Underwritten Offering on the terms set forth herein and such Purchaser
shall enter into an underwriting agreement upon customary terms with the
underwriter or underwriters selected by the Company.

 

(e) Notwithstanding anything herein to the contrary, the Company shall not be
required, pursuant to this Section 5.1, to include any Shares in a registration
statement if such Shares can then be sold pursuant to Rule 144(k) under the
Securities Act.

 

5.2 Limitations on Registration Rights.

 

(a) In the event that, in the good faith judgment of the Board of Directors, it
is advisable to suspend use of a prospectus included in a registration statement
covering the sale of the Shares due to pending material developments or other
events that have not yet been publicly disclosed and as to which the Company
believes public disclosure would be materially detrimental to the Company, the
Company shall notify the Purchaser to such effect, and, upon receipt of such
notice, the Purchaser shall immediately discontinue any sales of Shares pursuant
to such registration statement until the Purchaser has received copies of a
supplemented or amended prospectus or until the Purchaser is advised in writing
by the Company that the then current prospectus may be used and has received
copies of any additional or supplemental filings that are incorporated or deemed
incorporated by reference in such prospectus. Notwithstanding anything to the
contrary herein, the Company shall not exercise its rights under this Section
5.2(a) to suspend sales of Shares for a period in excess of 30 days
consecutively or 60 days in any 12-month period.

 

(b) If the Company suspends the registration statement covering the Shares or
requires the Purchaser to cease sales of shares pursuant to paragraph (a) above,
the Company shall, as promptly as practicable following the termination of the
circumstance which entitled the Company to do so, notify the Purchaser of such
termination and take such actions as may be necessary to reinstate the
effectiveness of such registration statement and/or give written notice to the
Purchaser authorizing it to resume sales pursuant to the such registration
statement. If as a result thereof the prospectus included in such registration
statement has been amended to

 

- 8 -

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

comply with the requirements of the Securities Act, the Company shall enclose
such revised prospectus with the notice to the Purchaser given pursuant to this
paragraph (b), and the Purchaser shall make no offers or sales of shares
pursuant to such registration statement other than by means of such revised
prospectus.

 

5.3 Registration Procedures.

 

(a) In connection with the filing by the Company of the registration statement
covering the Shares, the Company shall furnish to the Purchaser (i) a copy of
the prospectus, including a preliminary prospectus, in conformity with the
requirements of the Securities Act and (ii) such other documents as the
Purchaser may reasonably request, in order to facilitate the public sale or
other disposition of the Shares.

 

(b) The Company shall use its best efforts to register or qualify the Shares
covered by a registration statement under the securities laws of each state of
the United States as the Purchaser shall reasonably request; provided, however,
that the Company shall not be required in connection with this paragraph (b) to
qualify as a foreign corporation or execute a general consent to service of
process in any jurisdiction.

 

(c) If the Company has delivered preliminary or final prospectuses to the
Purchaser and after having done so the prospectus is amended or supplemented to
comply with the requirements of the Securities Act, the Company shall promptly
notify the Purchaser and, if requested by the Company, the Purchasers shall
immediately cease making offers or sales of Shares covered by a registration
statement and return all prospectuses to the Company. The Company shall promptly
provide the Purchaser with revised or supplemented prospectuses and, following
receipt of the revised or supplemented prospectuses, the Purchaser shall be free
to resume making offers and sales of Shares under such registration statement.

 

(d) The Company shall be entitled to include in a registration statement
covering the Shares the shares of Common Stock held by other stockholders of the
Company.

 

(e) The Company shall pay the expenses incurred by it in complying with its
registration obligations under this Section 5, including all registration and
filing fees, exchange listing fees, fees and expenses of counsel for the
Company, and fees and expenses of accountants for the Company, but excluding (i)
any brokerage fees, selling commissions or underwriting discounts incurred by
the Purchaser in connection with sales under any registration statement covering
the Shares and (ii) the fees and expenses of any counsel retained by the
Purchaser.

 

(f) The Company shall advise the Purchaser promptly after it shall receive
notice of any stop order by the SEC delaying or suspending the effectiveness of
a registration statement covering the Shares or of the initiation of any
proceeding for that purpose, and it will promptly use commercially reasonable
efforts to prevent the issuance of any stop order or to obtain its withdrawal at
the earliest possible moment if such stop order should be issued.

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

5.4 Requirements of the Purchaser.

 

(a) The Company shall not be required to include any Shares in any registration
statement unless the Purchaser furnishes to the Company in writing such
information regarding the Purchaser and the proposed sale of the Shares by the
Purchaser as the Company may reasonably request in writing in connection with
the registration statement or as shall be required in connection therewith by
the SEC or any state securities law authorities and the Purchaser shall have
provided to the Company its written agreement to use its commercially reasonable
efforts to report to the Company sales of the Shares.

 

(b) The Purchaser agrees to treat as confidential (unless otherwise publicly
disclosed by the Company or a third party not to the knowledge of Purchaser in
breach of an agreement of confidentiality with the Company) any written notice
from the Company regarding the Company’s plans to file a registration statement
and shall not disclose such information to any other person, or use such
information, except as is necessary to exercise its rights under this Agreement.

 

5.5 Indemnification.

 

(a) The Company agrees to indemnify and hold harmless the Purchaser, each
underwriter, and each other person, if any, who controls the Purchaser or
underwriter within the meaning of the Securities Act or Exchange Act from and
against any losses, claims, damages or liabilities to which the Purchaser, such
underwriter or controlling person may become subject (under the Securities Act,
the Exchange Act, state securities or Blue Sky laws or otherwise) insofar as
such losses, claims, damages or liabilities (or actions or proceedings in
respect thereof) arise out of, or are based upon any untrue statement of a
material fact contained in any registration statement covering the Shares or in
any preliminary prospectus or final prospectus contained in such registration
statement, or any amendment or supplement to such registration statement, or the
omission or alleged omission to state a material fact required to be stated
therein or necessary to make the statements therein not misleading, and the
Company will reimburse the Purchaser for any reasonable legal or other expenses
reasonably incurred in investigating, defending or preparing to defend any such
action, proceeding or claim, or preparing to defend any such action, proceeding
or claim; provided, however, that the Company shall not be liable in any such
case to the extent that such loss, claim, damage or liability arises out of, or
is based upon, an untrue statement made in such registration statement,
preliminary prospectus or prospectus, or any amendment or supplement in reliance
upon and in conformity with written information furnished to the Company by or
on behalf of the Purchaser specifically for use in the preparation thereof or
any statement or omission in any prospectus that is corrected in any subsequent
prospectus that was delivered to the Purchaser prior to the pertinent sale or
sales by the Purchaser.

 

(b) The Purchaser agrees to indemnify and hold harmless the Company, each
underwriter and each person, if any, who controls the Company within the meaning
of Section 15 of the Securities Act, each officer of the Company who signs the
registration statement and each director of the Company, from and against any
losses, claims, damages or liabilities to which the Company or any such
underwriter, officer, director or controlling person may become subject (under
the Securities Act, the Exchange Act, state

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

securities or Blue Sky laws or otherwise), insofar as such losses, claims,
damages or liabilities (or actions or proceedings in respect thereof) arise out
of, or are based upon any untrue statement of a material fact contained in any
registration statement covering the Shares or in any preliminary prospectus,
final prospectus contained in such registration statement, or any amendment or
supplement to such registration statement or the omission or alleged omission to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading, if such untrue statement or omission was made
in reliance upon and in conformity with written information furnished by or on
behalf of the Purchaser specifically for use in preparation of the registration
statement, prospectus, amendment or supplement and the Purchaser will reimburse
the Company, or such underwriter, officer, director or controlling person, as
the case may be, for any legal or other expenses reasonably incurred in
investigating, defending or preparing to defend any such action, proceeding or
claim; provided, however, that the Purchaser’s obligation to indemnify the
Company shall be limited to the net amount received by the Purchaser from the
sale of the Shares.

 

(c) Promptly after receipt by any indemnified person of a notice of a claim or
the beginning of any action in respect of which indemnity is to be sought
against an indemnifying person pursuant to this Section 5.5, such indemnified
person shall notify the indemnifying person in writing of such claim or of the
commencement of such action, but the omission to so notify the indemnifying
party will not relieve it from any liability which it may have to any
indemnified party under this Section 5.5 (except to the extent that such
omission materially and adversely affects the indemnifying party’s ability to
defend such action). Subject to the provisions hereinafter stated, in case any
such action shall be brought against an indemnified person, the indemnifying
person shall be entitled to participate therein, and, to the extent that it
shall elect by written notice delivered to the indemnified party promptly after
receiving the aforesaid notice from such indemnified party, shall be entitled to
assume the defense thereof, with counsel reasonably satisfactory to such
indemnified person. After notice from the indemnifying person to such
indemnified person of its election to assume the defense thereof, such
indemnifying person shall not be liable to such indemnified person for any legal
expenses subsequently incurred by such indemnified person in connection with the
defense thereof; provided, however, that if there exists or shall exist a
conflict of interest that would make it inappropriate, in the opinion of counsel
to the indemnified person, for the same counsel to represent both the
indemnified person and such indemnifying person or any affiliate or associate
thereof, the indemnified person shall be entitled to retain its own counsel at
the expense of such indemnifying person; provided, however, that no indemnifying
person shall be responsible for the fees and expenses of more than one separate
counsel (together with appropriate local counsel) for all indemnified parties.
In no event shall any indemnifying person be liable in respect of any amounts
paid in settlement of any action unless the indemnifying person shall have
approved the terms of such settlement; provided, however, that such consent
shall not be unreasonably withheld. No indemnifying person shall, without the
prior written consent of the indemnified person, effect any settlement of any
pending or threatened proceeding in respect of which any indemnified person is
or could have been a party and indemnification could have been sought hereunder
by such indemnified person, unless such settlement includes an unconditional
release of such indemnified person from all liability on claims that are the
subject matter of such proceeding.

(d) If the indemnification provided for in this Section 5.5 is unavailable to or
insufficient to hold harmless an indemnified party under paragraph (a) or (b)
above in respect of any losses, claims, damages or liabilities (or actions or
proceedings in respect thereof) referred to therein, then each indemnifying
party shall contribute to the amount paid or payable by such indemnified party
as a result of such losses, claims, damages or liabilities (or actions in
respect thereof) in such proportion as is appropriate to reflect the relative
fault of the Company on the one hand and the Purchaser, as well as any Other
Holders under such registration statement on the other hand, in connection with
the statements or omissions or other matters which resulted in such losses,
claims, damages or liabilities (or actions in respect thereof), as well as any
other relevant equitable considerations. The relative fault shall be determined
by reference to, among ether things, in the case of an untrue statement, whether
the untrue statement relates to information supplied by the Company on the one
hand or the Purchaser or Other Holder on the other hand and the parties’
relative intent, knowledge, access to information and opportunity to correct or
prevent such untrue statement. The Company and the Purchaser agree that it would
not be just and equitable if contribution pursuant to this paragraph (d) were
determined by pro rata allocation (even it the Purchaser and Other Holders were
treated as one entity for such purpose) or by any other method of allocation
which does not take into account the equitable considerations referred to above
in this paragraph (d). The amount paid or payable by an indemnified party as a
result of the losses, claims, damages or liabilities (or actions in respect
thereof) referred to above in this paragraph (d) shall be deemed to include any
legal or other expenses reasonably incurred by such indemnified party in
connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this paragraph (d), the Purchaser shall not be
required to contribute any amount in excess of the amount by which the net
amount received by the Purchaser from the sale of the Shares to which such loss
relates exceeds the amount of any damages which the Purchaser has otherwise been
required to pay by reason of such untrue statement. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation.

 

(e) The rights and obligation of the Company and the Purchaser under this
Section 5.5 shall survive the termination of this Agreement.

 

5.6 Termination. All of the Company’s obligations to register the Shares under
this Agreement shall terminate on the earlier of (a) the second anniversary of
the Closing Date, (b) the date on which all of the Shares have been sold by the
Purchaser or (c) a merger or consolidation of the Company, provided that the
Shares or shares received as merger consideration in exchange therefore are
freely tradable on a national securities exchange or NASDAQ.

 

6. Lock-Up Agreement. The Purchaser covenants and agrees that it will not, at
any time during the period beginning on the date hereof and ending on the date
that is 90 days after the Closing Date (the “Lock-up Period”), without the prior
written consent of the Company, (a) offer, pledge, sell, contract to sell, sell
any option or contract to purchase, purchase any option or contract to sell,
grant any option, right or warrant to purchase, lend, or otherwise transfer or
dispose of, directly or indirectly, contract to dispose of, or establish or
increase a put equivalent position or liquidate or decrease a call equivalent
position within the meaning of Section 16 of the Securities Exchange Act and the
rules and regulations of the SEC promulgated thereunder, with respect to any
shares of Common Stock or any securities convertible into or exercisable or

 

- 12 -

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

exchangeable for Common Stock, (b) enter into any swap or other arrangement that
transfers to another, in whole or in part, any of the economic consequences of
ownership of the Common Stock, in cash or otherwise, or (c) publicly announce an
intention to effect any transaction specified in clause (a) or (b) ); provided,
however, if the Collaboration Agreement is terminated prior to the end of the
Lock-up Period, then Purchaser shall no longer be subject to this provision.
Notwithstanding the foregoing or other limitations contained in this Agreement,
it is agreed and understood Purchaser shall be permitted without limitation to
contribute the Shares to any of Purchaser’s wholly-owned subsidiaries provided
that Purchaser and the transferee provide the Company with any documentation and
assurances reasonably requested by the Company relating to such transfer.

 

7. Notices. Any notices or other communications required or permitted hereunder
shall be sufficiently given if delivered personally or sent by telecopy or via a
reputable express courier, with charges prepaid, to the address set forth below
or to such other address of which the parties may have given notice. Unless
otherwise specified herein, such notices or other communications shall be deemed
