     1. Authorization and Sale of the Shares and Warrants. Subject to these
Terms and Conditions, the Company has authorized the sale of up to 6,777,363
Shares and Warrants to purchase up to 2,033,209 Warrant Shares. The Company
reserves the right to increase or decrease this number.

     2. Agreement to Sell and Purchase the Shares and Warrants; Subscription
Date.

          2.1 At the Closing (as defined in Section 3), the Company will sell to
the Investor, and the Investor will purchase from the Company, upon the terms
and conditions hereinafter set forth, the number of Shares and a Warrant to
purchase the number of Warrant Shares each as set forth in Section 3 of the
Stock and Warrant Purchase Agreement to which these Terms and Conditions are
attached at the purchase price set forth thereon.

          2.2 The Company may enter into the same form of Stock and Warrant
Purchase Agreement, including these Terms and Conditions, with certain other
investors (the “Other Investors”) and expects to complete sales of Shares and
Warrants to them. The Investor and the Other Investors are hereinafter sometimes
collectively referred to as the “Investors,” and the Stock and Warrant Purchase
Agreement to which these Terms and Conditions are attached and the Stock and
Warrant Purchase Agreements (including attached Terms and Conditions) executed
by the Other Investors are hereinafter sometimes collectively referred to as the
“Agreements.” The Company may accept executed Agreements from Investors for the
purchase of Shares and Warrants commencing upon the date on which the Company
provides the Investors with the proposed purchase price per Share plus Warrant
exercise price and concluding upon the date (the “Subscription Date”) on which
the Company has notified Lazard Frères & Co. LLC, in its capacity as placement
agent for this transaction, in writing that it is no longer accepting additional
Agreements from Investors for the purchase of Shares and Warrants. The Company
may not enter into any Agreements after the Subscription Date.

          2.3 The obligations of each Investor under any Agreement are several
and not joint with the obligations of any other Investor, and no Investor shall
be responsible in any way for the performance of the obligations of any other
Investor under any Agreement. Nothing contained herein, and no action taken by
any Investor hereto, shall be deemed to constitute the Investors as a
partnership, an association, a joint venture or any other kind of entity, or
create a presumption that the Investors are in any way acting in concert or as a
group with respect to such obligations or the transactions contemplated hereby,
provided that such obligations or the transactions contemplated hereby may be
modified, amended or waived in accordance with Section 9 below. Each Investor
shall be entitled to independently protect and enforce its rights, including
without limitation the rights arising out of this Agreement (provided, that such
rights may be modified, amended or waived in accordance with Section 9 below)
and the Warrant, and it shall not be necessary for any Other Investor to be
joined as an additional party in any proceeding for such purpose.

     3. Delivery of the Shares and Warrants at Closing. It is expected that the
completion of the purchase and sale of the Shares and Warrants (the “Closing”)
shall occur on or about November 9, 2004 (the “Closing Date”), at the offices of
the Company’s counsel. At the Closing, the Company shall deliver to the Investor
a Warrant representing the number of Warrant Shares and one or more stock
certificates representing the number of Shares, in each case as is set forth in
Section 3 of the Stock and Warrant Purchase Agreement, each such certificate to
be registered in the name of the Investor or, if so indicated on the signature
page of the Stock and Warrant Purchase Agreement, in the name of a nominee
designated by the Investor.

     The Company’s obligation to issue the Shares and the Warrant to the
Investor shall be subject to the following conditions, any one or more of which
may be waived by the Company: (a) receipt by the Company of a certified or
official bank check or wire transfer of funds in the full amount of the purchase
price for the Shares and the Warrant being purchased hereunder as set forth in
Section 3 of the Stock and Warrant Purchase Agreement; (b) completion of the
purchases and sales under the Agreements with the Other Investors; and (c) the
accuracy of the representations and warranties made by the Investors and the
fulfillment of those undertakings of the Investors to be fulfilled prior to the
Closing.

     The Investor’s obligation to purchase the Shares and the Warrant shall be
subject to the following conditions, any one or more of which may be waived by
the Investor: (a) the representations and warranties of the Company set forth
herein shall be true and correct as of the Closing Date (except for
representations and warranties that speak as of a specific date, which
representations and warranties shall be true and correct as of such date) in all
material respects and the fulfillment in all material respects of those

-1-

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

 

undertaking of the Company in this Agreement to be fulfilled on or prior to the
Closing Date and (b) the Investor shall have received such documents as such
Investor shall reasonably have requested, including, a standard opinion of the
Company’s counsel including as to the matters set forth in Section 4.2 and as to
exemption from the registration requirements of the Securities Act of 1933, as
amended (the “Securities Act”), of the sale of the Shares and Warrants.

     4. Representations, Warranties and Covenants of the Company. The Company
hereby represents and warrants to, and covenants with, the Investor, as follows:

          4.1 Organization. The Company is duly organized and validly existing
in good standing under the laws of the State of Delaware. The Company has full
power and authority to own or lease its properties and to conduct its business
as presently conducted and as described in the final prospectus contained in
Post-Effective Amendment No. 3 to its Registration Statement on Form S-1, filed
with the Securities and Exchange Commission on June 3, 2004 and in the documents
filed by the Company under the Securities Exchange Act of 1934, as amended, and
the rules and regulations promulgated thereunder (the “Exchange Act”), since the
end of its most recently completed fiscal year through the date hereof,
including, without limitation, its most recent report on Form 10-Q (the
“Disclosure Documents”) and is registered or qualified to do business and in
good standing in each jurisdiction in which the nature of the business conducted
by it or the location of the properties owned or leased by it requires such
qualification and where the failure to be so qualified would have a material
adverse effect upon the condition (financial or otherwise), earnings, business
or business prospects, properties or operations of the Company (a “Material
Adverse Effect”), and no proceeding has been instituted in any such
jurisdiction, revoking, limiting or curtailing, or seeking to revoke, limit or
curtail, such power and authority or qualification. The Company has no
subsidiaries (as defined in Rule 405 of the Securities Act).

          4.2 Due Authorization and Valid Issuance. The Company has all
requisite power and authority to execute, deliver and perform its obligations
under the Agreements and the Warrants, and the Agreements and the Warrants have
been duly authorized and validly executed and delivered by the Company and
constitute legal, valid and binding agreements of the Company enforceable
against the Company in accordance with their terms, except as rights to
indemnity and contribution may be limited by state or federal securities laws or
the public policy underlying such laws, except as enforceability may be limited
by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws
affecting creditors’ and contracting parties’ rights generally and except as
enforceability may be subject to general principles of equity (regardless of
whether such enforceability is considered in a proceeding in equity or at law).
The Shares being purchased by the Investor hereunder and the Warrant Shares
issuable pursuant to the Warrant will, upon issuance and payment therefor
pursuant to the terms hereof and thereof, be duly authorized, validly issued,
fully-paid and nonassessable. The Warrant being purchased by the Investor
hereunder will, upon issuance and payment therefor and pursuant to the terms
hereof and thereof, be duly authorized and validly issued.

          4.3 Non-Contravention. The execution and delivery of the Agreements
and the Warrants, the issuance and sale of the Shares and the Warrants under the
Agreements and the Warrant Shares under the Warrant, the fulfillment of the
terms of the Agreements and the Warrants and the consummation of the
transactions contemplated thereby will not (A) conflict with or constitute a
violation of, or default (with the passage of time or otherwise) under, (i) any
bond, debenture, note or other evidence of indebtedness, lease, contract,
indenture, mortgage, deed of trust, loan agreement, joint venture or other
agreement or instrument to which the Company is a party or by which it or its
properties are bound, (ii) the charter, by-laws or other organizational
documents of the Company, or (iii) any law, administrative regulation, ordinance
or order of any court or governmental agency, arbitration panel or authority
applicable to the Company or its properties, except in the case of clauses
(i) and (iii) for any such conflicts, violations or defaults that are not
reasonably likely to have a Material Adverse Effect or (B) result in the
creation or imposition of any lien, encumbrance, claim, security interest or
restriction whatsoever upon any of the properties or assets of the Company or an
acceleration of indebtedness pursuant to any obligation, agreement or condition
contained in any bond, debenture, note or any other evidence of indebtedness or
any indenture, mortgage, deed of trust or any other agreement or instrument to
which the Company is a party or by which it is bound or to which any of the
material property or assets of the Company is subject, except for such liens,
encumbrances, claims, security interests or restrictions upon any of the
properties or assets of the Company or accelerations of indebtedness that are
not reasonably likely to have a Material Adverse Effect. No consent, approval,
authorization or other order of, or registration, qualification or filing with,
any regulatory body, administrative agency, or other governmental body or any
other person is required for the execution and delivery of the Agreements and
the Warrants, and the valid issuance and sale of the Shares and Warrants to be
sold pursuant to the Agreements, and the valid issuance of the Warrant Shares
under the Warrant, other than such as have been made or obtained, and except for
any post-closing securities filings or notifications required to be made under
federal or state securities laws.

          4.4 Capitalization. The capitalization of the Company as of June 30,
2004 is as set forth in the most recent applicable Disclosure Documents,
increased as set forth in the next sentence. The Company has not issued any
capital stock since

-2-

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

 

that date other than pursuant to (i) employee benefit plans disclosed in the
Disclosure Documents, or (ii) outstanding warrants, options or other securities
disclosed in the Disclosure Documents and (iii) shares of Common Stock issued in
connection with the exercise of the overallotment option in the Company’s
initial public offering. The Shares and the Warrants to be sold pursuant to the
Agreements, and the Warrant Shares to be issued pursuant to the Warrants, have
been duly authorized, and when they are issued and paid for in accordance with
the terms of the Agreements and the Warrants, as the case may be, the Shares and
Warrant Shares will be duly and validly issued, fully paid and nonassessable.
The outstanding shares of capital stock of the Company have been duly and
validly issued and are fully paid and nonassessable, have been issued in
compliance with all federal and state securities laws, and were not issued in
violation of any preemptive rights or similar rights to subscribe for or
purchase securities. Except as set forth in or contemplated by the Disclosure
Documents, and other than options issued to officers, directors and employees of
the Company under its employee benefit plans, there are no outstanding rights
(including, without limitation, preemptive rights), warrants or options to
acquire, or instruments convertible into or exchangeable for, any unissued
shares of capital stock or other equity interest in the Company, or any
contract, commitment, agreement, understanding or arrangement of any kind to
which the Company is a party or of which the Company has knowledge and relating
to the issuance or sale of any capital stock of the Company, any such
convertible or exchangeable securities or any such rights, warrants or options.
Without limiting the foregoing, no preemptive right, co-sale right, right of
first refusal or other similar right exists with respect to the Shares, the
Warrants or the Warrant Shares or the issuance and sale thereof. No further
approval or authorization of any stockholder, the Board of Directors of the
Company or others is required for the issuance and sale of the Shares, the
Warrants and the Warrants Shares. Except as disclosed in the Disclosure
Documents, there are no stockholders agreements, voting agreements or other
similar agreements with respect to the Common Stock to which the Company is a
party or, to the knowledge of the Company, between or among any of the Company’s
stockholders. The issuance and sale of the Shares will not result in a right of
any current holder of Company securities to adjust the exercise, conversion,
exchange or reset price under such securities. Subject to the filing of the
notification with the Nasdaq National Market, the issuance and sale of the
Shares and Warrant Shares under this Agreement does not contravene the rules and
regulations of the Nasdaq National Market, and, in furtherance of the foregoing
sentence, no approval of the stockholders of the Company thereunder is required
for the Company to issue and deliver to the Investor the maximum number of
Shares and Warrant Shares contemplated by this Agreement.

          4.5 Legal Proceedings; Disagreements with Advisors. There is no
material legal or governmental investigations, actions, suits or proceeding
pending or, to the knowledge of the Company, threatened to which the Company is
or may be a party or of which the business or property of the Company is subject
that is not disclosed in the Disclosure Documents. There are no material
disagreements presently existing, or reasonably anticipated by the Company to
arise, between the accountants formerly or presently employed by the Company.

          4.6 No Violations. The Company is not (i) in violation of its charter,
bylaws, or other organizational document; (ii) in violation of any federal,
state or local law, administrative regulation, ordinance or order of any court
or governmental agency, arbitration panel or authority applicable to the
Company, which violation, individually or in the aggregate, would be reasonably
likely to have a Material Adverse Effect; or (iii) in default (and there exists
no condition which, with the passage of time or otherwise, would constitute a
default) in the performance of any bond, debenture, note or any other evidence
of indebtedness in any indenture, mortgage, deed of trust or any other agreement
or instrument to which the Company is a party or by which the Company is bound
or by which the properties of the Company are bound, which would be reasonably
likely to have a Material Adverse Effect.

          4.7 Governmental Permits, Etc. With the exception of the matters which
are dealt with separately in Sections 4.1, 4.12, 4.13, and 4.14, the Company has
all necessary franchises, licenses, certificates and other authorizations from
any foreign, federal, state or local government or governmental agency,
department, or body that are currently necessary for the operation of the
business of the Company as currently conducted and as described in the
Disclosure Documents except where the failure to currently possess would not
have a Material Adverse Effect.

          4.8 Intellectual Property. Except as specifically disclosed in the
Disclosure Documents (i) the Company owns or possesses sufficient rights to use
all patents, patent rights, trademarks, copyrights, licenses, inventions, trade
secrets, trade names and know-how (including trade secrets and other unpatented
and/or unpatentable property or confidential information, systems, processes or
procedures) (collectively, “Intellectual Property”) described or referred to in
the Disclosure Documents as owned or possessed by it or that are necessary for
the conduct of its business as now conducted as described in the Disclosure
Documents except where the failure to currently own or possess would not have a
Material Adverse Effect, (ii) the Company is not infringing, and has not
received any notice of, and has no knowledge of, any asserted infringement by
the Company of any rights of a third party with respect to any Intellectual
Property that, individually or in the aggregate, would have a Material Adverse
Effect and (iii) the Company has not received any notice of, and has no
knowledge of, infringement by a third party with respect to any Intellectual
Property rights of the Company that, individually or in the aggregate, would
have a Material Adverse Effect. Further,

-3-

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

 

except as described in the Disclosure Documents or exhibits thereto, or as would
not reasonably be expected, individually or in the aggregate, to have a Material
Adverse Effect, no third party, including any academic or governmental
organization, possesses rights to the Intellectual Property which, if exercised,
could enable such third party to develop products competitive with the business
of the Company as currently being conducted.

financial statements of the Company and the related notes contained in the
Disclosure Documents present fairly, in accordance with generally accepted
accounting principles, the financial position of the Company as of the dates
indicated, and the results of its operations and cash flows for the periods

a consistent basis throughout the periods therein specified, except as may be

published rules and regulations of the SEC with respect thereto.

          (b) Except as set forth in any Disclosure Documents, there are no
obligations of the Company to officers, directors, stockholders or employees of
the Company other than (i) for payment of salary for services rendered and for
bonus payments; (ii) reimbursements for reasonable expenses incurred on behalf
of the Company; (iii) for other standard employee benefits made generally
available to all employees (including stock option agreements outstanding under
any stock option plan approved by the Board of Directors of the Company); and
(iv) obligations listed in the Company’s financial statements.

          4.10 No Material Adverse Change. Except as disclosed in the Disclosure

Company which has been sustained which has a Material Adverse Effect.

          4.11 Disclosure. The representations and warranties of the Company
contained in this Section 4 as of the date hereof and as of the Closing Date, do
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. Except
with respect to the material terms and conditions of the transaction
contemplated by the Agreements and the Warrants, the anticipated use of the
proceeds therefrom, which shall be publicly disclosed by the Company pursuant to
Section 16 hereof, the Company confirms that neither it nor any person acting on
its behalf has provided the Investors with any information that the Company
believes constitutes material, non-public information. The Company understands
and confirms that the Investors will rely on the foregoing representations in
effecting transactions in the securities of the Company.

          4.12 NASDAQ Compliance. The Company’s Common Stock is registered
pursuant to Section 12(g) of the Exchange Act and is listed on The Nasdaq Stock
Market, Inc. National Market (the “Nasdaq National Market”), and the Company has
taken no action designed to, or likely to have the effect of, terminating the
registration of the Common Stock under the Exchange Act or de-listing the Common
Stock from the Nasdaq National Market, nor has the Company received any
notification that the SEC or the National Association of Securities Dealers,
Inc. (“NASD”) is contemplating terminating such registration or listing.

          4.13 Reporting Status. The Company has filed in a timely manner all
documents that the Company was required to file under the Exchange Act during
the 12 months preceding the date of this Agreement. The following documents
complied in all material respects with the SEC’s requirements as of their

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:

          4.15 No Manipulation of Stock. The Company has not taken and will not,
in violation of applicable law, take, any action designed to or that might
reasonably be expected to cause or result in stabilization or manipulation of
the price of the Common Stock to facilitate the sale or resale of the Shares or
the Warrant Shares.

          4.16 Company not an “Investment Company”. The Company has been advised
of the rules and requirements under the Investment Company Act of 1940, as
amended (the “Investment Company Act”). The Company is not, and immediately
after receipt of payment for the Shares and Warrants and the Warrant Shares will
not be, an “investment company” or an entity “controlled” by an “investment
company” within the meaning of the Investment Company Act and shall conduct its
business in a manner so that it will not become subject to the Investment
Company Act.

          4.17 Foreign Corrupt Practices. Neither the Company, nor to the
knowledge of the Company, any agent or other person acting on behalf of the
Company, has (i) directly or indirectly, used any corrupt funds for unlawful

foreign or domestic government officials or employees or to any foreign or

          4.19 Contracts. The contracts described in the Disclosure Documents
that are material to the Company are in full force and effect on the date
hereof, and neither the Company nor, to the Company’s knowledge, any other party

termination under any of such contracts which would have a Material Adverse
Effect. The Company has filed with the SEC all contracts and agreements required
to be filed by the Exchange Act.

          4.20 Taxes. The Company has filed (or has obtained an extension of
time within which to file) all necessary federal, state and foreign income and
franchise tax returns and has paid all taxes shown as due on such tax returns,
except where the failure to so file or the failure to so pay would not have a
Material Adverse Effect. The Company is not aware of any tax deficiency that has
been or might be asserted or threatened against it that would have a Material
Adverse Effect.

          4.21 Private Offering. Assuming the correctness of the representations
and warranties of the Investors set forth in Section 5 hereof and assuming that
Lazard Frères & Co. LLC has not offered or sold any of the Shares and the
Warrants by any form of general solicitation or advertising, the offer and sale

of the Company which would bring the offer, issuance or sale of the Shares and
the Warrants as contemplated by this Agreement, or the issuance of the Warrant
Shares pursuant to the Warrant, within the provisions of Section 5 of the
Securities Act, unless such offer, issuance or sale was or shall be within the
exemptions of Section 4 of the Securities Act. Neither the Company nor any
person acting on behalf of the Company (other than Lazard Frères & Co. LLC) has

compliance with all provisions of the Sarbanes-Oxley Act of 2002 which are

statements in conformity with GAAP and to maintain asset accountability,
(iii) access to assets is permitted only in accordance with management’s general
or specific authorization, and (iv) the recorded accountability for assets is
compared with the existing assets at reasonable intervals and appropriate action
is taken with respect to any differences. The Company’s certifying officers are

(as defined in the Exchange Act) for the Company and they have (a) designed such
disclosure controls and procedures, or caused such disclosure controls and
procedures to be designed under their supervision, to ensure that material
information relating to the Company is made known to the certifying officers by
others within those entities, particularly during the periods in which the
Company’s filings under the Exchange Act have been prepared; (b) evaluated the
effectiveness of the Company’s disclosure controls and procedures and presented
in the Company’s filings under the Exchange Act their conclusions about the
effectiveness of the disclosure controls and procedures, as of the end of the
periods covered by such filings under the Exchange Act based on such evaluation;
and (c) since the last evaluation date referred to in (b) above, there have been
no material changes in the Company’s internal control over financial reporting
(as such term is defined in the Exchange Act) or, to the Company’s knowledge, in
other factors that could significantly affect the Company’s internal control
over financial reporting.

          4.23 Transactions With Affiliates. There are no business relationships
or related-party transactions involving the Company or any other person required
to be described in the Disclosure Documents that have not been described as
required.

Statement (as defined below), no person will have the right, which right has not
been waived, to require the Company to register any securities for sale under
the Securities Act by reason of the filing of the Registration Statement with
the SEC or the issuance and sale of the Shares, Warrants or Warrant Shares.

          4.25 Company Acknowledgement of Investor Representation. The Company
acknowledges and agrees that Investor does not make or has not made any
representations or warranties with respect to the transactions contemplated
hereby other than those specifically set forth in Sections 5 and 16(a) of this
Agreement, or in the Investor Questionnaire.

     5. Representations, Warranties and Covenants of the Investor.

          5.1 The Investor represents and warrants to, and covenants with, the
Company that: (i) the Investor is an “accredited investor” as defined in
Regulation D under the Securities Act and the Investor is also knowledgeable,
sophisticated and experienced in making, and is qualified to make decisions with
respect to investments in shares presenting an investment decision like that
involved in the purchase of the Shares and the Warrant, including investments in
securities issued by the Company and investments in comparable companies, and
has requested, received, reviewed and considered all information it deemed
relevant in making an informed decision to purchase the Shares and the Warrant;
(ii) the Investor is acquiring the Warrant to purchase the number of Warrant
Shares and the number of Shares, each as set forth in Section 3 of the Stock and
Warrant Purchase Agreement in the ordinary course of its business and for its
own account for investment only and with no present intention of distributing
any of such Shares, Warrants or Warrant Shares or any arrangement or
understanding with any other persons regarding the distribution of such Shares,
Warrant or Warrant Shares; (iii) the Investor will not, directly or indirectly,
offer, sell, pledge, transfer or otherwise dispose of (or solicit any offers to
buy, purchase or otherwise acquire or take a pledge of) any of the Shares,
Warrant or Warrant Shares except in compliance with the Securities Act,
applicable state securities laws and the respective rules and regulations
promulgated thereunder; (iv) the Investor has answered all questions on the
Investor Questionnaire for use in preparation of the Registration Statement and
the answers thereto are true, correct and complete as of the date hereof and
will be true, correct and complete as of the Closing Date; (v) the Investor will
notify the Company immediately of any change in any of such information until
such time as the Investor has sold all of its Shares and Warrant Shares or until
the Company is no longer required to keep the Registration Statement effective;
and (vi) the Investor has, in connection with its decision to purchase the
number of Shares and the Warrant to purchase the number of Warrant Shares, each
as set forth in Section 3 of the Stock and Warrant Purchase Agreement relied
only upon the Disclosure Documents and the representations and warranties of the
Company contained herein. The Investor understands that its acquisition of the
Shares and the Warrant has not been registered under the Securities Act or
registered or qualified under any state securities law in reliance on specific
exemptions therefrom, which exemptions may depend upon, among other things, the
bona fide nature of the Investor’s investment intent as expressed herein.
Subject to compliance with the Securities Act, applicable securities laws and
the respective rules and regulations promulgated thereunder, nothing contained
herein shall be deemed a representation or warranty by such Investor to hold the
Shares, Warrant or Warrant Shares for any period of time. The

-6-

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

 

Investor has completed or caused to be completed and delivered to the Company
the Investor Questionnaire, which questionnaire is true, correct and complete in
all material respects.

          5.2 The Investor acknowledges, represents and agrees that no action
has been or will be taken in any jurisdiction outside the United States by the
Company that would permit an offering of the Shares, Warrant or Warrant Shares
or possession or distribution of offering materials in connection with the issue
of the Shares, Warrant or Warrant Shares in any jurisdiction outside the United
States where legal action by the Company for that purpose is required. Each
Investor outside the United States will comply with all applicable laws and
regulations in each foreign jurisdiction in which it purchases, offers, sells or
delivers Shares, the Warrant or Warrant Shares or has in its possession or
distributes any offering material, in all cases at its own expense.

          5.3 The Investor hereby covenants with the Company not to make any
sale of the Shares, Warrant or Warrant Shares without complying with the
provisions of this Agreement and without causing the prospectus delivery
requirement under the Securities Act to be satisfied (whether by delivery of the
Prospectus or pursuant to and in compliance with an exemption from such
requirement), and the Investor acknowledges that the certificates evidencing the
Shares and Warrant Shares will be imprinted with a legend that prohibits their
transfer except in accordance therewith. The Investor acknowledges that there
may occasionally be times when the Company determines that it must suspend the
use of the Prospectus forming a part of the Registration Statement, as set forth
in Section 7.2(c).

          5.4 The Investor further represents and warrants to, and covenants
with, the Company that (i) the Investor has full right, power, authority and
capacity to enter into this Agreement and to consummate the transactions
contemplated hereby and has taken all necessary action to authorize the
execution, delivery and performance of this Agreement, and (ii) this Agreement
constitutes a valid and binding obligation of the Investor enforceable against
the Investor in accordance with its terms, except as enforceability may be
limited by applicable bankruptcy, insolvency, reorganization, moratorium or
similar laws affecting creditors’ and contracting parties’ rights generally and
except as enforceability may be subject to general principles of equity
(regardless of whether such enforceability is considered in a proceeding in
equity or at law) and except as the indemnification agreements of the Investors
herein may be legally unenforceable.

          5.5 Between the time the Investor learned about the Offering and the
public announcement of the Offering, the Investor has not engaged in any short
sales or similar transactions with respect to the Common Stock, nor has the
Investor, directly or indirectly, caused any person to engage in any short sales
or similar transactions with respect to the Common Stock. Without limiting the
foregoing, Investor will not use any of the Shares acquired pursuant to this
Agreement to cover any short position in the Common Stock of the Company if
doing so would be in violation of applicable securities laws.

          5.6 The Investor understands that nothing in the Disclosure Documents,
this Agreement or any other materials presented to the Investor in connection
with the purchase and sale of the Shares and the Warrant constitutes legal, tax
or investment advice. The Investor has consulted such legal, tax and investment
advisors as it, in its sole discretion, has deemed necessary or appropriate in
connection with its purchase of Shares and the Warrant.

     6. Survival of Representations, Warranties and Agreements. Notwithstanding
any investigation made by any party to this Agreement, all covenants,
agreements, representations and warranties made by the Company and the Investor
herein shall survive the execution of this Agreement, the delivery to the
Investor of the Shares and the Warrant being purchased and the payment therefor,
provided that the representations and warranties contained herein shall expire
on the one-year anniversary of the Closing Date.

     7. Registration of the Shares; Compliance with the Securities Act.

          7.1 Registration Procedures and Other Matters. The Company shall:

               (a) subject to receipt of necessary information from the
Investors after prompt request from the Company to the Investors to provide such
information, prepare and file with the SEC, within 30 days after the Closing
Date, a registration statement on Form S-1 (the “S-1 Registration Statement”) to
enable the resale of the Shares and the Warrant Shares by the Investors from
time to time in compliance with the Securities Act;

-7-

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

 

               (b) subject to receipt of necessary information from the
Investors after prompt request from the Company to the Investors to provide such
information, use its best efforts to cause the S-1 Registration Statement to
become effective within 105 days after the Closing Date such efforts to include,
without limiting the generality of the foregoing, preparing and filing with the
SEC in such period any financial statements that are required to be filed prior
to the effectiveness of such S-1 Registration Statement; and the Company shall
use its best efforts, subject to receipt of necessary information from the
Investors after prompt request from the Company to the Investors to provide such
information, to prepare and file with the SEC, within 30 days after the Company
first becomes eligible to file a registration statement on Form S-3 (or an
amendment to the Registration Statement on Form S-3) (the “S-3 Registration
Statement”) to enable the resale of the Shares and the Warrant Shares by the
Investors from time to time in compliance with the Securities Act; and to use
its best efforts to cause the S-3 Registration Statement to become effective as
soon as practicable thereafter, such efforts to include, without limiting the
generality of the foregoing, preparing and filing with the SEC as promptly as
practicable any financial statements that are required to be filed prior to the
effectiveness of such S-3 Registration Statement (the term “Registration
Statement” shall mean the S-1 or S-2 Registration Statement until the S-3
Registration Statement is declared effective by the SEC, after which time it
shall mean the S-3 Registration Statement).

               (c) use its best efforts to prepare and file with the SEC such
amendments and supplements to the Registration Statement in compliance with
applicable laws, and the prospectus used in connection therewith (the
“Prospectus”) as may be necessary to keep the Registration Statement current,
effective and free from any material misstatement or omission to state a
material fact for a period not exceeding, with respect to each Investor’s Shares
purchased hereunder and the Warrant Shares purchased under the Warrant, the
earlier of (i) the second anniversary of the Closing Date, (ii) the date on
which the Investor may sell all Shares and Warrant Shares then held by the
Investor without restriction by the volume limitations of Rule 144(e) of the
Securities Act, or (iii) such time as all Shares purchased by such Investor in
this offering and Warrant Shares issuable pursuant to the Warrant have been sold
pursuant to a registration statement;

               (d) furnish to the Investor with respect to the Shares and
Warrant Shares registered under the Registration Statement such number of copies
of the Registration Statement, Prospectuses and Preliminary Prospectuses in
conformity with the requirements of the Securities Act and such other documents
as the Investor may reasonably request, in order to facilitate the public sale
or other disposition of all or any of the Shares or Warrant Shares by the
Investor;

               (e) file documents required of the Company for blue sky clearance
in states specified in writing by the Investor and use its commercially
reasonable efforts to maintain such blue sky qualifications during the period
the Company is required to maintain the effectiveness of the Registration
Statement pursuant to Section 7.1(c); provided, however, that the Company shall
not be required to qualify to do business or consent to service of process in
any jurisdiction in which it is not now so qualified or has not so consented;

               (f) bear all expenses in connection with the procedures in
paragraph (a) through (e), (h) and the last paragraph of this Section 7.1 and
the registration of the Shares and Warrant Shares pursuant to the Registration
Statement (other than underwriting discounts or commissions, brokers’ fees and
similar selling expenses and any other fees or expenses incurred by the
Investor, including attorneys’ fees); and

               (g) advise the Investor, promptly after it shall receive notice
or obtain knowledge of the issuance of any stop order by the SEC delaying or
suspending the effectiveness of the Registration Statement or of the initiation
or threat of any proceeding for that purpose; and it will promptly use its
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; and

               (h) provide a “Plan of Distribution” section of the Registration
Statement to the Investor for such Investor’s review and comment which, at a
minimum, states that the selling stockholders may transfer the shares of common
stock in various circumstances, including circumstances in which the
transferees, pledgees or other successors in interest may be the selling
beneficial owners for purposes of the Prospectus.

     Notwithstanding anything to the contrary herein, the Registration Statement
shall cover only the Shares and the Warrant Shares. In no event at any time
before the Registration Statement becomes effective with respect to the Shares
and the Warrant Shares shall the Company publicly announce or file any other
registration statement, other than registrations on Form S-8, without the prior
written consent of a majority in interest of the Investors.

     The Company understands that the Investor disclaims being an underwriter,
but the Investor being deemed an underwriter by the SEC shall not relieve the
Company of any obligations it has hereunder; provided, however that if the
Company receives

-8-

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

 

notification from the SEC that the Investor is deemed an underwriter, then the
period by which the Company is obligated to submit an acceleration request to
the SEC shall be extended to the earlier of (i) the 90th day after such SEC
notification, or (ii) 120 days after the initial filing of the Registration
Statement with the SEC.

     Within five business days of the effectiveness date of the Registration
Statement, the Company shall give notice to the Investor of such effectiveness
and use its commercially reasonable efforts to cause its counsel to issue an
appropriate opinion or opinions to the transfer agent substantially to the
effect that the shares are subject to an effective registration statement and
can be reissued free of restrictive legend upon notice of a sale by an Investor
and confirmation by such Investor that it has complied with the prospectus
delivery requirements in the form attached hereto as Exhibit A, provided that
the Company has not advised the transfer agent orally or in writing that the
opinion has been withdrawn.

          7.2 Transfer of Shares and Warrant Shares After Registration;
Suspension.

               (a) The Investor agrees that it will not effect any disposition
of the Shares or the Warrant Shares or its right to purchase the Shares or the
Warrant Shares that would constitute a sale within the meaning of the Securities
Act except as contemplated in the Registration Statement referred to in
Section 7.1 and as described below or as otherwise permitted by law, and that it
will promptly notify the Company of any changes in the information set forth in
the Registration Statement regarding the Investor or its plan of distribution.
In connection with any transfer of Shares or Warrant Shares other than pursuant
to an effective registration statement, to the Company or to an affiliate of the
Investor (who is an accredited investor and executes a customary representation
letter), the Company may require the transferor thereof to provide to the
Company an opinion of counsel which opinion shall be reasonably satisfactory to
the Company, to the effect that such transfer does not require registration of
such transferred Shares or Warrant Shares under the Securities Act.

               (b) Except in the event that paragraph (c) below applies, the
Company shall (i) if deemed necessary by the Company, prepare and file from time
to time with the SEC a post-effective amendment to the Registration Statement or
a supplement to the related Prospectus or a supplement or amendment to any
document incorporated therein by reference or file any other required document
so that such Registration Statement will not contain an 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 not misleading, and so that, as
thereafter delivered to purchasers of the Shares and Warrant Shares being sold
thereunder, such Prospectus will not contain an 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; (ii) provide the Investor copies of any documents
filed pursuant to Section 7.2(b)(i) as they reasonably request; and (iii) inform
each Investor that the Company has complied with its obligations in
Section 7.2(b)(i) (or that, if the Company has filed a post-effective amendment
to the Registration Statement which has not yet been declared effective, the
Company will notify the Investor to that effect, will use its best efforts to
secure the effectiveness of such post-effective amendment as promptly as
possible and will promptly notify the Investor pursuant to Section 7.2(b)(i)
hereof when the amendment has become effective).

               (c) Subject to paragraph (d) below, in the event (i) of any
request by the SEC or any other federal or state governmental authority during
the period of effectiveness of the Registration Statement for amendments or
supplements to a Registration Statement or related Prospectus or for additional
information; (ii) of the issuance by the SEC or any other federal or state
governmental authority of any stop order suspending the effectiveness of a
Registration Statement or the initiation of any proceedings for that purpose;
(iii) of the receipt by the Company of any notification with respect to the
suspension of the qualification or exemption from qualification of any of the
Shares or the Warrant Shares for sale in any jurisdiction or the initiation or
threatening of any proceeding for such purpose; or (iv) of any event or
circumstance which, upon the good faith judgment of the Company’s Board of
Directors based on the advice of its counsel, necessitates the making of any
changes in the Registration Statement or Prospectus, or any document
incorporated or deemed to be incorporated therein by reference, so that, in the
case of the Registration Statement, it will not contain any untrue statement of
a material fact or any omission to state a material fact required to be stated
therein or necessary to make the statements therein not misleading, and that in
the case of the Prospectus, it will not contain any untrue statement of a
material fact or any omission to state a material fact required to be stated
therein or necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading; then the Company shall
deliver a certificate in writing to the Investor (the “Suspension Notice”) to
the effect of the foregoing and, upon receipt of such Suspension Notice, the
Investor will refrain from selling any Shares and Warrant Shares pursuant to the
Registration Statement (a “Suspension”) until the Investor’s receipt of copies
of a supplemented or amended Prospectus prepared and filed by the Company, or
until it is advised in writing by the Company that the current Prospectus may be
used, and has received copies of any additional or supplemental filings that are
incorporated or deemed incorporated by reference in any such Prospectus. In the
event of any Suspension, the Company will use its best efforts to cause the use
of the Prospectus so suspended to be resumed as soon as reasonably practicable
within 20 business days after the delivery of a Suspension Notice to the
Investor.

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

 

               (d) Notwithstanding the foregoing paragraphs of this Section 7.2,
the Investor shall not be prohibited from selling Shares or Warrant Shares under
the Registration Statement as a result of Suspensions on more than two occasions
of not more than 30 days each in any twelve month period, unless, in the good
faith judgment of the Company’s Board of Directors based on the advice of its
counsel, the sale of Shares and Warrant Shares under the Registration Statement
in reliance on this paragraph 7.2(d) would be reasonably likely to cause a
violation of the Securities Act or the Exchange Act and result in liability to
the Company.

               (e) Provided that a Suspension is not then in effect, the
Investor may sell Shares and Warrant Shares under the Registration Statement,
provided that it arranges for delivery of a current Prospectus to the transferee
of such Shares or Warrant Shares. Upon receipt of a request therefor, the
Company has agreed to provide an adequate number of current Prospectuses to the
Investor and to supply copies to any other parties requiring such Prospectuses
pursuant to the Securities Act.

               (f) In the event of a sale of Shares or Warrant Shares by the
Investor pursuant to the Registration Statement, the Investor must also deliver
to the Company’s transfer agent, with a copy to the Company, a Certificate of
Subsequent Sale substantially in the form attached hereto as Exhibit A, so that
the Shares and Warrant Shares may be properly transferred.

          7.3 Indemnification. For the purpose of this Section 7.3:

          (i) the term “Selling Stockholder” means the Investor and any
affiliate of such Investor;

          (ii) the term “Registration Statement” shall include the Prospectus in
the form first filed with the SEC pursuant to Rule 424(b) of the Securities Act
or filed as part of the Registration Statement at the time of effectiveness if
no Rule 424(b) filing is required, exhibit, supplement or amendment included in
or relating to the Registration Statement referred to in Section 7.1; and

          (iii) the term “untrue statement” for purposes of Section 7.3(d)
hereof shall include any untrue statement or alleged untrue statement, or any
omission or alleged omission to state in the Registration Statement a material
fact required to be stated therein or necessary to make the statements therein,
in the light of the circumstances under which they were made, not misleading.

               (a) The Company agrees to indemnify and hold harmless each
Selling Stockholder from and against any losses, claims, damages or liabilities
to which such Selling Stockholder may become subject (under the Securities Act
or otherwise) insofar as such losses, claims, damages or liabilities (or actions
or proceedings in respect thereof) arise out of, or are based upon (i) any
breach of the representations or warranties of the Company contained herein or
failure to comply with the covenants and agreements of the Company contained
herein, (ii) any untrue statement of a material fact contained in the
Registration Statement as amended at the time of effectiveness or any omission
of a material fact required to be stated therein or necessary to make the
statements therein not misleading, or (iii) any failure by the Company to
fulfill any undertaking included in the Registration Statement as amended at the
time of effectiveness, and the Company will reimburse such Selling Stockholder
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 or any omission of a material fact
required to be stated therein or necessary to make the statements therein not
misleading in reliance upon and in conformity with written information furnished
to the Company by or on behalf of such Selling Stockholder specifically for use
in preparation of the Registration Statement, or the failure of such Selling
Stockholder to comply with its covenants and agreements contained in Section 7.2
hereof respecting sale of the Shares or Warrant Shares or any statement or
omission in any Prospectus that is corrected in any subsequent Prospectus that
was delivered to the Selling Stockholder prior to the pertinent sale or sales by
the Selling Stockholder. The Company shall reimburse each Selling Stockholder
for the amounts provided for herein on demand as such expenses are incurred as
reasonably documented by the Selling Stockholder.

               (b) The Investor agrees to indemnify and hold harmless the
Company (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
officer, director or controlling person) may become subject (under the
Securities Act or otherwise), insofar as such losses, claims, damages or
liabilities (or actions or proceedings in respect thereof) arise out of, or are
based upon, (i) any failure to comply with the covenants and agreements
contained in Section 7.2 hereof respecting sale of the Shares and Warrant

-10-

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

 

Shares, (ii) any untrue statement of a material fact contained in the
Registration Statement or any omission of 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 Investor specifically for
use in preparation of the Registration Statement, and the Investor will
reimburse the Company (or such 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, or (iii) any breach of the representations and warranties of the Investor
contained in Section 5 of this Agreement; provided that Investor’s obligation to
indemnify the Company shall be limited to the net amount received by the
Investor from the sale of the Shares and Warrant 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 7.3, 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 person will not relieve it from any liability which it may have to
any indemnified person under this Section 7.3 (except to the extent that such
omission materially and adversely affects the indemnifying person’s ability to
defend such action) or from any liability otherwise than under this Section 7.3.
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 person promptly after receiving the aforesaid
notice from such indemnified person, 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
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 7.3 is
unavailable to or insufficient to hold harmless an indemnified person under
subsection (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 person shall contribute to the amount paid or payable by
such indemnified person 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 Investor,
as well as any other Selling Stockholders under such registration statement on
the other 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 other things, in the case of an
untrue statement, whether the untrue statement relates to information supplied
by the Company on the one hand or an Investor or other Selling Stockholder on
the other and the parties’ relative intent, knowledge, access to information and
opportunity to correct or prevent such untrue statement. The Company and the
Investor agree that it would not be just and equitable if contribution pursuant
to this subsection (d) were determined by pro rata allocation (even if the
Investor and other Selling Stockholders 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 subsection (d). The
amount paid or payable by an indemnified person as a result of the losses,
claims, damages or liabilities (or actions in respect thereof) referred to above
in this subsection (d) shall be deemed to include any legal or other expenses
reasonably incurred by such indemnified person in connection with investigating
or defending any such action or claim. Notwithstanding the provisions of this
subsection (d), the Investor shall not be required to contribute any amount in
excess of the amount by which the net amount received by the Investor from the
sale of the Shares and Warrant Shares to which such loss relates exceeds the
amount of any damages which such Investor 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. The Investor’s obligations in this subsection to
contribute shall be in proportion to its sale of Shares and Warrant Shares to
which such loss relates and shall not be joint with any other Selling
Shareholders.

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

 

               (e) The parties to this Agreement hereby acknowledge that they
are sophisticated business persons who were represented by counsel during the
negotiations regarding the provisions hereof including, without limitation, the
provisions of this Section 7.3, and are fully informed regarding said
provisions. They further acknowledge that the provisions of this Section 7.3
fairly allocate the risks in light of the ability of the parties to investigate
the Company and its business in order to assure that adequate disclosure is made
in the Registration Statement as required by the Securities Act and the Exchange
Act. The parties are advised that federal or state public policy as interpreted
by the courts in certain jurisdictions may be contrary to certain of the
provisions of this Section 7.3, and the parties hereto hereby expressly waive
and relinquish any right or ability to assert such public policy as a defense to
a claim under this Section 7.3 and further agree not to attempt to assert any
such defense.

          7.4 Termination of Conditions and Obligations. The conditions
precedent imposed by Section 5 or this Section 7 upon the transferability of the
Shares and Warrant Shares shall cease and terminate as to any particular number
of the Shares or Warrant Shares when such shares shall have been effectively
registered under the Securities Act and sold or otherwise disposed of in
accordance with the intended method of disposition set forth in the Registration
Statement covering such shares or at such time as an opinion of counsel
reasonably satisfactory to the Company shall have been rendered to the effect
that such conditions are not necessary in order to comply with the Securities
Act.

          7.5 Information Available. So long as the Registration Statement is
effective covering the resale of Shares and Warrant Shares owned by the
Investor, the Company will furnish to the Investor:

               (a) as soon as practicable after it is available, one copy of
(i) its Annual Report to Stockholders (which Annual Report shall contain
financial statements audited in accordance with generally accepted accounting
principles by a national firm of certified public accountants), (ii) its Annual
Report on Form 10-K and (iii) its Quarterly Reports on Form 10-Q (the foregoing,
in each case, excluding exhibits);

               (b) upon the reasonable request of the Investor, all exhibits
excluded by the parenthetical to subparagraph (a) of this Section 7.5 as filed
with the SEC and all other information that is made available to shareholders;
and

               (c) upon the reasonable request of the Investor, an adequate
number of copies of the Prospectuses to supply to any other party requiring such
Prospectuses; and upon the reasonable request of the Investor, the President or
the Chief Financial Officer of the Company (or an appropriate designee thereof)
will meet with the Investor or a representative thereof at the Company’s
headquarters to discuss all information relevant for disclosure in the
Registration Statement covering the Shares and Warrant Shares and will otherwise
cooperate with any Investor conducting an investigation for the purpose of
reducing or eliminating such Investor’s exposure to liability under the
Securities Act, including the reasonable production of information at the
Company’s headquarters; provided, that the Company shall not be required to
disclose any confidential information to or meet at its headquarters with any
Investor until and unless the Investor shall have entered into a confidentiality
agreement in form and substance reasonably satisfactory to the Company with the
Company with respect thereto.

          7.6 Legend; Restrictions on Transfer. (a) The certificate or
certificates for the Shares, Warrants and Warrant Shares (and any securities
issued in respect of or exchange for the Shares or Warrant Shares) shall be
subject to a legend or legends restricting transfer under the Securities Act and
referring to restrictions on transfer herein, such legend to be substantially as
follows:

THE SECURITIES REPRESENTED BY THIS CERTIFICATE (THE “SECURITIES”) HAVE BEEN

               (b) Such certificates shall not contain any legend (i) following
any sale of such Shares and Warrant Shares pursuant to an effective Registration
Statement or Rule 144, or (ii) if such Shares and Warrant Shares are eligible
for sale under Rule 144(k). Following such time as a legend is no longer

five (5) trading days following the delivery by a Investor to the Company or the
Company’s transfer agent of a legended certificate representing such securities,
deliver or cause to be delivered to such Investor a certificate representing
such securities that is free from all restrictive and other legends.

          7.7 Liquidated Damages. The Company and Investor agree that Investor
will suffer damages if the Company fails to fulfill its obligations pursuant to
Section 7.1 and 7.2 hereof and that it would not be possible to ascertain the
extent of such damages with precision. Accordingly, the Company hereby agrees to
pay liquidated damages (“Liquidated Damages”) to Investor under the following
circumstances: (a) if the Registration Statement is not filed by the Company on
or prior to 30 days after the Closing Date (such an event, a “Filing Default”);
(b) if the Registration Statement is not declared effective by the SEC on or
prior to 105 days after the Closing Date (such an event, an “Effectiveness
Default”); (c) if the Registration Statement (after its effectiveness date)
ceases to be effective and available to Investor prior to June 30, 2005 for more
than 60 days in the aggregate; or (d) if the Registration Statement ceases to be
effective and available to Investor after June 30, 2005 for any continuous
period that exceeds 30 days or for one or more periods that exceed in the
aggregate 60 days in any 12-month period (such an event, a “Suspension Default”
and together with a Filing Default and an Effectiveness Default, a “Registration
Default”). In the event of a Registration Default, the Company shall as
Liquidated Damages pay to Investor, for each 30-day period of a Registration
Default, an amount in cash equal to 1% of the aggregate purchase price paid by
Investor pursuant to this Agreement; provided that in no event shall the
aggregate amount of cash to be paid as Liquidated Damages pursuant to this
Section 7.7 exceed 10% of the aggregate purchase price paid by Investor. The
Company shall pay the Liquidated Damages as follows: (i) in connection with a
Filing Default, on the 31st day after the Closing Date, and each 30th day
thereafter until the Registration Statement is filed with the SEC; (ii) in
connection with an Effectiveness Default, on the 106th day after the Closing
Date, and each 30th day thereafter until the Registration Statement is declared
effective by the SEC; or (iii) in connection with a Suspension Default, on
either (x) the 61st day (in the aggregate) of any Suspensions prior to June 30,
2005 or (y) after June 30, 2005, the 31st consecutive day of any Suspension or
the 61st day (in the aggregate) of any Suspensions in any 12-month period, and,
in the case of clauses (x) and (y), each 30th day thereafter until the
Suspension is terminated in accordance with Section 7.2. Notwithstanding the
foregoing, all periods shall be tolled during delays directly caused by the
action or inaction of any Investor, and the Company shall have no liability to
any Investor in respect of any such delay. The Liquidated Damages payable herein
shall apply on a pro rata basis for any portion of a 30-day period of a
Registration Default.

     14. Entire Agreement. This Agreement and the Warrants constitute the entire

extent required from time to time to enable such Investor to sell such Shares
and Warrant Shares without registration under the Securities Act within the
limitation of the exemptions provided by (a) Rule 144 under the Securities Act,
as such Rule may be amended from time to time, or (b) any similar rule or
regulation hereafter adopted by the SEC. Upon the request of the Investor, the
Company will deliver to such holder a written statement as to whether it has
complied with such information and requirements.

     16. Confidential Information.

          (a) The Investor represents to the Company that, at all times during
the Company’s offering of the Shares and the Warrants, the Investor has
maintained in confidence all non-public information regarding the Company

violation of this provision by the Investor or its agents or (b) is required to
be disclosed in legal proceedings (such as by deposition, interrogatory, request
for documents, subpoena, civil investigation demand, filing with any
governmental authority or similar process), provided, however, that before

INVESTOR QUESTIONNAIRE

(ALL INFORMATION WILL BE TREATED CONFIDENTIALLY)

     
To:
  Inhibitex, Inc. 1165 Sanctuary Parkway, Suite 400 Alpharetta, GA 30004

     This Investor Questionnaire (“Questionnaire”) must be completed by each
potential investor in connection with the offer and sale of the shares of the
common stock, par value $0.001 per share, of Inhibitex, Inc. (“Common Stock”)
and warrants to purchase shares of Common Stock (collectively, the
“Securities”). The Securities are being offered and sold by Inhibitex, Inc. (the
“Corporation”) without registration under the Securities Act of 1933, as amended
(the “Act”), and the securities laws of certain states, in reliance on the
exemptions contained in Section 4(2) of the Act and on Regulation D promulgated
thereunder and in reliance on similar exemptions under applicable state laws.
The Corporation must determine that a potential investor meets certain
suitability requirements before offering or selling Securities to such investor.
The purpose of this Questionnaire is to assure the Corporation that each
investor will meet the applicable suitability requirements. The information
supplied by you will be used in determining whether you meet such criteria, and
reliance upon the private offering exemption from registration is based in part
on the information herein supplied.

     This Questionnaire does not constitute an offer to sell or a solicitation
of an offer to buy any security. Your answers will be kept strictly
confidential. However, by signing this Questionnaire you will be authorizing the
Corporation to provide a completed copy of this Questionnaire to such parties as
the Corporation deems appropriate in order to ensure that the offer and sale of
the Securities will not result in a violation of the Act or the securities laws
of any state and that you otherwise satisfy the suitability standards applicable
to purchasers of the Securities. All potential investors must answer all
applicable questions and complete, date and sign this Questionnaire. Please
print or type your responses and attach additional sheets of paper if necessary
to complete your answers to any item.

contributions to an IRA or KEOGH retirement plan, alimony payments, and any
amount by which income from long-term capital gains has been reduced in arriving
at adjusted gross income.

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

 

2.   The information contained herein is complete and accurate and may be relied
upon by the Corporation, and the undersigned will notify the Corporation
immediately of any material change in any of such information occurring prior to
the closing, if any, with respect to the purchase of Securities by the
undersigned or any co-purchaser.   3.   There are no suits, pending litigation,
or claims against the undersigned that could materially affect the net worth of
the undersigned as reported in this Questionnaire.   4.   The undersigned
acknowledges that there may occasionally be times when the Corporation
determines that it must suspend the use of the Prospectus forming a part of the
Registration Statement (as such terms are defined in the Stock and Warrant
Purchase Agreement to which this Questionnaire is attached), as set forth in
Section 7.2(c) of the Stock and Warrant Purchase Agreement. The undersigned is
aware that, in such event, the Securities will not be subject to ready
liquidation, and that any Securities purchased by the undersigned would have to
be held during such suspension. The overall commitment of the undersigned to
investments which are not readily marketable is not excessive in view of the
undersigned’s net worth and financial circumstances, and any purchase of the
Securities will not cause such commitment to become excessive. The undersigned
is able to bear the economic risk of an investment in the Securities.   5.   The
undersigned is aware of its obligations under applicable federal and state
securities laws with respect to use and disclosure of non-public information
regarding the Company.   6.   The undersigned has carefully considered the
potential risks relating to the Corporation and a purchase of the Securities,
and fully understands that the Securities are speculative investments which
involve a high degree of risk of loss of the undersigned’s entire investment.
Among others, the undersigned has carefully considered each of the risks
identified in the Disclosure Documents.   7.   The undersigned understands that
the Securities that it is acquiring are characterized as “restricted securities”
under the federal securities laws inasmuch as they are being acquired in a
transaction not involving a public offering, and that under such laws and
applicable regulations such securities may be resold without registration under
the Act, only in certain limited circumstances. In this connection, the
undersigned represents that it is familiar with SEC Rule 144, as presently in
effect, and understands the resale limitations imposed thereby and by the Act.  
8.   It us understood that the certificates evidencing the Securities shall bear
a legend, reading substantially as follows:

      THE SECURITIES REPRESENTED BY THIS CERTIFICATE (THE “SECURITIES”) HAVE
BEEN ISSUED AND SOLD IN RELIANCE UPON EXEMPTIONS FROM REGISTRATION UNDER THE

REASONABLY SATISFACTORY TO IT WITH RESPECT TO COMPLIANCE OF THE PROPOSED SALE OR
TRANSFER WITH THE REGISTRATION REQUIREMENTS OF THE 1933 ACT OR EXEMPTION

     Re: Inhibitex, Inc.; Registration Statement on Form S-1

Dear Selling Shareholder:

     Enclosed please find five (5) copies of a prospectus dated             ,
   (the “Prospectus”) for your use in reselling your shares of common stock,
$0.001 par value (the “Shares”), of Inhibitex, Inc. (the “Company”), under the
Company’s Registration Statement on Form S-1 (Registration No. 333-
            ) (the “Registration Statement”), which has been declared effective
by the Securities and Exchange Commission. As a selling shareholder under the
Registration Statement, you have an obligation to deliver a copy of the
Prospectus to each purchaser of your Shares, either directly or through the
broker-dealer who executes the sale of your Shares.

     The Company is obligated to notify you in the event that it suspends
trading under the Registration Statement in accordance with the terms of the
Stock and Warrant Purchase Agreement between the Company and you. During the
period that the Registration Statement remains effective and trading thereunder
has not been suspended, you will be permitted to sell your Shares that are
included in the Prospectus under the Registration Statement. Upon a sale of any
Shares under the Registration Statement, you or your broker will be required to
deliver to the Transfer Agent, American Stock Transfer & Trust Company (1) your
restricted stock certificate(s) representing the Shares, (2) instructions for
transfer of the Shares sold, and (3) a representation letter from your broker,
or from you if you are selling in a privately negotiated transaction, or from
such other appropriate party, in the form of Exhibit A attached hereto (the
“Representation Letter”). The Representation Letter confirms that the Shares
have been sold pursuant to the Registration Statement and in a manner described
under the caption “Plan of Distribution” in the Prospectus and that such sale
was made in accordance with all applicable securities laws, including the
prospectus delivery requirements.

     Please note that you are under no obligation to sell your Shares during the
registration period. However, if you do decide to sell, you must comply with the
requirements described in this letter or otherwise applicable to such sale. Your
failure to do so may result in liability under the Securities Act of 1933, as
amended, and the Securities Exchange Act of 1934, as amended. Please remember
that all sales of your Shares must be carried out in the manner set forth under
the caption “Plan of Distribution” in the Prospectus if you sell under the
Registration Statement. The Company may require an opinion of counsel reasonably
satisfactory to the Company if you choose another method of sale. You should
consult with your own legal advisor(s) on an ongoing basis to ensure your
compliance with the relevant securities laws and regulations.

     In order to maintain the accuracy of the Prospectus, you must notify the
undersigned upon the sale, gift, or other transfer of any Shares by you,
including the number of Shares being transferred, and in the event of any other
change in the information regarding you which is contained in the Prospectus.
For example, you must notify the undersigned if you enter into any arrangement
with a broker-dealer for the sale of shares through a block trade, special
offering, exchange distribution or secondary distribution or a purchase by a
broker-dealer. Depending on the circumstances, such transactions may require the
filing of a supplement to the prospectus in order to update the information set
forth under the caption “Plan of Distribution” in the Prospectus.

     Should you need any additional copies of the Prospectus, or if you have any
questions concerning the foregoing, please write to me at Inhibitex, Inc., 1165
Sanctuary Parkway, Suite 400, Alpharetta, GA 30004. Thank you.

validly issued, fully paid and nonassessable Common Stock, par value $.001 per
share, (as adjusted pursuant to Section 4 hereof, the “Warrant Shares”) of
INHIBITEX, INC., a Delaware corporation (the “Company”), at the price of $8.81
per share (such price and such other price as shall result, from time to time,
from the adjustments specified in Section 4 hereof is herein referred to as the
“Warrant Price”), subject to the provisions and upon the terms and conditions
hereinafter set forth. As used herein the term “Date of Grant” shall mean
November    , 2004. The term “Warrant” as used herein shall be deemed to include
any warrants issued upon transfer or partial exercise of this Warrant unless the
context clearly requires otherwise. This Warrant has been issued pursuant to a
Stock and Warrant Purchase Agreement, dated as of November    , 2004, between
the Company and the registered holder of this Warrant (the “Purchase
Agreement”), and is subject to the terms and conditions set forth therein.
Capitalized Terms not otherwise defined herein shall have the meanings ascribed
to them in the Purchase Agreement.

     1. Term. The purchase right represented by this Warrant is exercisable, in
whole or in part, at any time and from time to time from the date which is One
Hundred Eighty (180) days from the Date of Grant through November    , 2009.

     2. Method of Exercise; Payment; Issuance of New Warrant. Subject to
Section 1 hereof, the purchase right represented by this Warrant may be
exercised by the holder hereof, in whole or in part and from time to time, at
the election of the holder hereof, by (a) the surrender of this Warrant (with
the notice of exercise substantially in the form attached hereto as Exhibit A
duly completed and executed) at the principal office of the Company and the
payment to the Company, by certified or bank check, or by wire transfer to an
account designated by the Company of an amount equal to the then applicable
Warrant Price multiplied by the number of Warrant Shares then being purchased,
or (b) exercise of the “net issuance” right provided for in Section 10.2 hereof.
The person or persons in whose name(s) any certificate(s) representing the
Warrant Shares shall be issuable upon exercise of this Warrant shall be deemed
to have become the holder(s) of record of, and shall be treated for all purposes
as the record holder(s) of, the shares represented thereby (and such shares
shall be deemed to have been issued) immediately prior to the close of business
on the date or dates upon which this Warrant is exercised. In the event of any
exercise of the rights represented by this Warrant, certificates for the shares
of stock so purchased shall be delivered to the holder hereof as soon as
practicable and, if requested by the holder of

 

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

 

this Warrant, the Company shall cause its transfer agent to deliver the
certificate representing Warrant Shares issued upon exercise of this Warrant to
a broker or other person (as directed by the holder exercising this Warrant, but
subject to the payment by the holder of any applicable transfer taxes) within
the time period required to settle any trade made by the holder after exercise
of this Warrant.

     3. Stock Fully Paid; Reservation of Warrant Shares. All Warrant Shares that
may be issued upon the exercise of the rights represented by this Warrant will,
upon issuance pursuant to the terms and conditions herein, be fully paid and
nonassessable, and free from all taxes, liens and charges with respect to the
issue thereof. During the period within which the rights represented by this
Warrant may be exercised, the Company will at all times have authorized, and
reserved for the purpose of the issue upon exercise of the purchase rights
evidenced by this Warrant, a sufficient number of shares of its Common Stock to
provide for the exercise of the rights represented by this Warrant.

     4. Adjustment of Warrant Price and Number of Warrant Shares. The number and
kind of securities purchasable upon the exercise of this Warrant and the Warrant
Price shall be subject to adjustment from time to time upon the occurrence of
certain events, as follows:

          (a) Reclassification or Merger. In case of any reclassification or
change of securities of the class issuable upon exercise of this Warrant (other
than a change in par value, or from par value to no par value, or from no par
value to par value, or as a result of a subdivision or combination), or in case
of any merger of the Company with or into another corporation (other than a
merger with another corporation in which the Company is the surviving
corporation and which does not result in any reclassification or change of
outstanding securities issuable upon exercise of this Warrant), the Company, or
such surviving corporation, as the case may be, shall duly execute and deliver
to the holder of this Warrant a new Warrant (which, if not in substantially the
form of this Warrant, shall be in form and substance reasonably satisfactory to
the holder of this Warrant), or the Company shall make appropriate provision
without the issuance of a new Warrant, so that the holder of this Warrant shall
have the right to receive upon exercise of this Warrant, at a total purchase
price not to exceed that payable upon the exercise of the then unexercised
portion of this Warrant, and in lieu of the shares of Common Stock theretofore
issuable upon exercise of this Warrant, the kind and amount of shares of stock,
other securities, money and property receivable upon such reclassification,
change or merger by a holder of the number of shares of Common Stock purchasable
under this Warrant immediately preceding the consummation of such
reclassification or merger. Such new Warrant shall provide for adjustments that
shall be as nearly equivalent as may be practicable to the adjustments provided
for in this Section 4. The provisions of this subparagraph (a) shall similarly
apply to successive reclassifications, changes and mergers.

          (b) Subdivision or Combination of Warrant Shares. If the Company at
any time while this Warrant remains outstanding and unexpired shall subdivide or
combine its outstanding shares of Common Stock, the Warrant Price shall be
proportionately decreased and the number of Warrant Shares issuable hereunder
shall be proportionately increased in the case of a subdivision and the Warrant
Price shall be proportionately increased and the number of Warrant Shares
issuable hereunder shall be proportionately decreased in the case of a
combination.

          (c) Stock Dividends. If the Company at any time while this Warrant is
outstanding and unexpired shall pay a dividend with respect to its Common Stock
payable in Common Stock, then the Warrant Price shall be adjusted, from and
after the record date fixed for the determination of the shareholders of the
Company entitled to receive such dividend or distribution, to that price
determined by multiplying the Warrant Price in effect immediately prior to such
date of determination by a fraction (A) the numerator of which shall be the
total number of shares of Common Stock outstanding immediately prior to such
dividend or distribution, and (B) the denominator of which shall be the total
number of shares of Common Stock outstanding immediately after such dividend or
distribution.

2

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

 

          (d) Adjustment of Number of Warrant Shares. Upon each adjustment in
the Warrant Price pursuant to Section 4(c) above, the number of Warrant Shares
purchasable hereunder shall be adjusted, to the nearest whole share, to the
product obtained by multiplying the number of Warrant Shares purchasable
immediately prior to such adjustment in the Warrant Price by a fraction, the
numerator of which shall be the Warrant Price immediately prior to such
adjustment and the denominator of which shall be the Warrant Price immediately
thereafter.

     5. Notice of Adjustments. Whenever the Warrant Price or the number of
Warrant Shares purchasable hereunder shall be adjusted pursuant to Section 4
hereof, the Company shall make a certificate signed by its chief financial
officer setting forth, in reasonable detail, the event requiring the adjustment,
the amount of the adjustment, the method by which such adjustment was
calculated, and the Warrant Price and the number of Warrant Shares purchasable
hereunder after giving effect to such adjustment, and shall cause copies of such
certificate to be mailed (without regard to Section 13 hereof) by first class
mail, postage prepaid to the holder of this Warrant at such holder’s last known
address.

     6. Fractional Shares. No fractional shares of Common Stock will be issued
in connection with any exercise hereunder, but in lieu of such fractional shares
the Company shall make a cash payment therefor based on the fair market value of
the Common Stock on the date of exercise as reasonably determined in good faith
by the Company’s Board of Directors.

     7. Compliance with Securities Act. This Warrant and all Warrant Shares
issued upon exercise of this Warrant (unless registered under the Securities Act
and any applicable state securities laws) shall be stamped or imprinted with a
legend in substantially the form as set forth in the Purchase Agreement. Said
legend shall be removed by the Company, upon the request of a holder, at such
time as the restrictions on the transfer of the applicable security shall have
terminated.

     8. Rights as Shareholders; Information. No holder of this Warrant, as such,
shall be entitled to vote or receive dividends or be deemed the holder of Common
Stock or any other securities which may at any time be issuable on the exercise
hereof for any purpose, nor shall anything contained herein be construed to
confer upon the holder of this Warrant, as such, any of the rights of a
stockholder of the Company or any right to vote for the election of directors or
upon any matter submitted to shareholders at any meeting thereof, or (except as
provided in Section 10.1) to receive notice of meetings, or to receive dividends
or subscription rights or otherwise until this Warrant shall have been exercised
and the Warrant Shares purchasable upon the exercise hereof shall have become
deliverable, as provided herein.

     9. Registration Rights. The Company has granted registration rights to the
holder of this Warrant for the resale of the Common Stock of the Company
obtained upon exercise hereof, pursuant to the Purchase Agreement.

     10. Additional Rights.

10.1 Notice of Corporate Action. In the event the Company proposes to: (i) pay,
distribute, or take a record of the holders of its Common Stock for the purpose
of determining the holders thereof who are entitled to receive, any dividend or
other distribution, or any right to subscribe for, purchase or otherwise acquire
any shares of capital stock or any other securities or property, or
(ii) consummate any capital reorganization, reclassification, recapitalization,
consolidation, merger, transfer of all or substantially all of the Company’s
assets, dissolution, liquidation or winding-up, or any similar transaction,
then, at least 10 days prior to the earlier of any applicable record date or
such event, as the case may be, the Company shall mail to the holder of this
Warrant a notice specifying: (a) the date or expected date on which any such
payment or distribution is to be made or record is to be taken and the amount
and character of any such dividend, distribution or right; (b) the date or
expected date on which any such reorganization,

3

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

 

reclassification, recapitalization, consolidation, merger, transfer,
dissolution, liquidation, winding-up or similar transaction is to take effect
and any record date therefor; (c) the time as of which any holders of record of
shares of Common Stock and/or any other class of securities shall be entitled to
exchange their shares of Common Stock and/or other securities for the securities
or other property deliverable upon such reorganization, reclassification,
recapitalization, consolidation, merger, transfer, dissolution, liquidation,
winding-up or similar transaction and a description in reasonable detail of such
transaction; and (d) in each case, the expected effect on the Warrant Price of
each such transaction or event. The Company shall update any such notice to
reflect any change in the foregoing information.

     10.2 Right to Convert Warrant into Stock: Net Issuance.

          (a) Right to Convert. In addition to and without limiting the rights
of the holder under the terms of this Warrant, the holder shall have the right
to convert this Warrant or any portion thereof (the “Conversion Right”) into
shares of Common Stock as provided in this Section 10.2 at any time or from time
to time during the term of this Warrant. Upon exercise of the Conversion Right
with respect to a particular number of Warrant Shares subject to this Warrant
(the “Converted Warrant Shares”), the Company shall deliver to the holder
(without payment by the holder of any exercise price or any cash or other
consideration) that number of shares of fully paid and nonassessable Common
Stock as is determined according to the following formula:

     
X =
  B - A

     Y

     
Where: X =
 
the number of shares of Common Stock to be issued to the holder upon such
exercise
 
   
Y =
  the fair market value of one share of Common Stock
 
   
A =
 
the aggregate Warrant Price of the specified number of Converted Warrant Shares
immediately prior to the exercise of the Conversion Right (i.e., the number of
Converted Warrant Shares multiplied by the Warrant Price)
 
   
B =
 
the aggregate fair market value of the specified number of Converted Warrant
Shares (i.e., the number of Converted Warrant Shares multiplied by the fair
market value of one Converted Warrant Share)

No fractional shares shall be issuable upon exercise of the Conversion Right,
and, if the number of shares to be issued determined in accordance with the
foregoing formula is other than a whole number, the Company shall pay to the
holder an amount in cash equal to the fair market value of the resulting
fractional share on the Conversion Date (as hereinafter defined). For purposes
of Section 9 of this Warrant, shares issued pursuant to the Conversion Right
shall be treated as if they were issued upon the exercise of this Warrant.

          (b) Method of Exercise. The Conversion Right may be exercised by the
holder by the surrender of this Warrant at the principal office of the Company
together with a written statement (which may be in the form of Exhibit A)
specifying that the holder thereby intends to exercise the Conversion Right and
indicating the number of shares subject to this Warrant which are being
surrendered (referred to in Section 10.2(a) hereof as the Converted Warrant
Shares) in

4

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

 

exercise of the Conversion Right. Such conversion shall be effective upon
receipt by the Company of this Warrant together with the aforesaid written
statement, or on such later date as is specified therein (the “Conversion
Date”). Certificates for the Warrant Shares issuable upon exercise of the
Conversion Right and, if applicable, a new Warrant evidencing the balance of the
Warrant Shares remaining subject to this Warrant, shall be issued as of the
Conversion Date and shall be delivered to the holder within thirty (30) days
following the Conversion Date.

          (c) Determination of Fair Market Value. For purposes of this
Section 10.2, “fair market value” of a share of Common Stock as of a particular
date (the “Determination Date”) shall mean:

               (i) If traded on a securities exchange, the Nasdaq National
Market or Nasdaq SmallCap Market, the fair market value of the Common Stock
shall be deemed to be the average of the closing prices of the Common Stock on
such exchange or market over the five trading days immediately prior to the
Determination Date;

               (ii) If traded on the Nasdaq Stock Market (other than the Nasdaq
National Market or Nasdaq SmallCap Market) or other over-the-counter system, the
fair market value of the Common Stock shall be deemed to be the average of the
closing bid prices of the Common Stock over the five trading days immediately
prior to the Determination Date; and

               (iii) If there is no public market for the Common Stock, then
fair market value shall be determined by (A) mutual agreement of the holders of
a majority-in-interest of the warrants issued pursuant to the Purchase Agreement
who are then seeking to exercise their Conversion Rights (the “Converting
Holders”) and the Company or (B) if no such mutual agreement can be reached
within 15 days, then the higher of (x) the book value of a share of the Common
Stock as determined by a firm of independent public accountants selected (within
10 days after the failure of the Company and the Converting Holders to reach
mutual agreement) by the Board of Directors of the Company with the consent of
the holders of the majority-in-interest of the warrants issued pursuant to the
Purchase Agreement that are beneficially owned by Converting Holders, which
consent shall not be unreasonably withheld or delayed, as at the last day of any
month ending within 60 days preceding the date as of which the determination is
to be made (such determination of the independent public accountant to be
completed within 30 days after such independent public accountant is chosen by
the Company and the Converting Holders) or (y) the fair value thereof determined
in good faith by an independent appraiser (chosen within 10 days after the
failure of the Company and the Converting Holders to reach mutual agreement by
the Board of Directors of the Company with the consent of the Converting Holder
exercising the Conversion Right with respect to the greatest number of shares,
which consent shall not be unreasonably withheld or delayed) as of a date which
is within 15 days of the date as of which the determination is to be made (such
determination of the independent appraiser to be completed within 30 days after
such independent appraiser is chosen by the Company and the Converting Holders).
The fees and expenses of any such independent public accountant or independent
appraiser shall be borne one half by the Converting Holders (among the
Converting Holders, pro rata according to the number of shares for which
Conversion Rights are being exercised) and one half by the Company.

If closing prices or closing bid prices are no longer reported by a securities
exchange or other trading system, the closing price or closing bid price shall
be that which is reported by such securities exchange or other trading system at
4:00 p.m. New York City time on the applicable trading day.

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

 

10.3 Exercise Prior to Expiration. To the extent this Warrant is not previously
exercised as to all of the Warrant Shares subject hereto, and if the fair market
value of one share of the Common Stock is greater than the Warrant Price then in
effect, this Warrant shall be deemed automatically exercised pursuant to
Section 10.2 above (even if not surrendered) immediately before its expiration.
For purposes of such automatic exercise, the fair market value of one share of
Common Stock upon such expiration shall be determined pursuant to
Section 10.2(c). To the extent this Warrant or any portion thereof is deemed
automatically exercised pursuant to this Section 10.3, the Company agrees to
promptly notify the holder hereof of the number of Warrant Shares, if any, the
holder hereof is to receive by reason of such automatic exercise.

majority of the number of Warrant Shares then issuable upon exercise of the
Warrants sold in the Offering (as such terms are defined in the Purchase
Agreement), provided that such modification, amendment or waiver is made with
respect to all Warrants issued in the Offering and does not adversely affect the
holder of this Warrant without adversely affecting all Investors in a similar
manner; or (ii) the holder of this Warrant.

or permitted to be given or delivered to the holder hereof or the Company shall

securities laws, this Warrant may be transferred by the holder with respect to
any or all of the Warrant Shares. Upon surrender of this Warrant to the Company,
together with the assignment hereof properly endorsed, for transfer of this
Warrant as an entirety by the holder, the Company shall issue a new warrant of
the same denomination to the assignee. Upon surrender of this Warrant to the
Company, together with the assignment hereof properly endorsed, by the Holder
for transfer with respect to a portion of the Warrant Shares purchasable
hereunder, the Company shall issue a new warrant to the assignee, in such
denomination as shall be requested by the holder hereof, and shall issue to such
holder a new warrant covering the number of Warrant Shares in respect of which
this Warrant shall not have been transferred.

      14. Binding Effect on Successors. This Warrant shall be binding upon any
corporation succeeding the Company by merger or consolidation and all of the
obligations of the Company relating to the Warrant Shares issuable upon the
exercise or conversion of this Warrant shall survive the exercise, conversion
and termination of this Warrant and all of the covenants and agreements of the
Company shall inure to the benefit of the successors and assigns of the holder
hereof.

      15. Lost Warrants or Stock Certificates. The Company covenants to the
holder hereof that, upon receipt of evidence reasonably satisfactory to the
Company of the loss, theft, destruction or mutilation of this Warrant or any
stock certificate and, in the case of any such loss, theft or destruction, upon
receipt of an indemnity reasonably satisfactory to the Company, or in the case
of any such mutilation upon surrender and cancellation of such Warrant or stock
certificate, the Company will make and deliver a new Warrant or stock
certificate, of like tenor, in lieu of the lost, stolen, destroyed or mutilated
