thereunder. The execution and delivery of each of the Transaction Documents to which it is a party
by the Company and the consummation by it of the transactions contemplated hereby and thereby
(including, but not limited to, the sale and delivery of the Shares and the Warrants and the
subsequent issuance of the Warrant Shares upon exercise of the Warrants) have been duly authorized
by all necessary corporate action on the part of the Company and no further corporate action is
required by the Company, its Board of Directors or its stockholders. Each Transaction Document to
which it is a party has been (or upon delivery will have been) duly executed by the Company and,
when delivered in accordance with the terms hereof, will constitute the valid and binding
obligation of the Company enforceable against the Company in accordance with its terms, except as

moratorium, liquidation or similar laws relating to, or affecting generally the enforcement of,
creditors’ rights and remedies or by other equitable principles of general application.

(d) No Conflicts. The execution, delivery and performance of the Transaction

Subsidiary debt or otherwise) or other understanding to which the Company or the Subsidiary is a
party or by which any property or asset of the Company or the Subsidiary is bound, or affected,

restriction of any court or governmental authority to which the Company or the Subsidiary is
subject (including federal and state securities laws and regulations and the rules and regulations,
assuming the correctness of the representations and warranties made by the Purchasers herein, of

pursuant to Item 404 of Regulation S-K promulgated under the Securities Act.

(u) Sarbanes Oxley Act. The Company is in compliance with applicable requirements of
the Sarbanes Oxley Act of 2002 and applicable rules and regulations promulgated by the Commission
thereunder, except where such noncompliance would not have, individually or in the aggregate, a
Material Adverse Effect.

(v) Accounting Controls. The Company and the Subsidiary maintain a system of internal
accounting controls sufficient to provide reasonable assurance that (i) transactions are executed
in accordance with management’s general or specific authorizations, (ii) transactions are recorded
as necessary to permit preparation of financial statements in conformity with generally accepted
accounting principles 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

(w) Certain Fees. Except for the cash commission to be paid (the “Cash Placement
Agent Fees”) and Warrants to be issued to the Placement Agent pursuant to the terms of the
Placement Agent Agreement, no Person will have, as a result of the transactions contemplated by
this Agreement, any valid right, interest or claim against or upon the Company or any Purchaser for
any commission, fee or other compensation pursuant to any agreement, arrangement or understanding
entered into by or on behalf of the Company.

(x) Private Placement. Assuming the accuracy of the Purchasers’ representations and
warranties set forth in Section 3.2(b)-(e), no registration under the Securities Act is required
for the offer and sale of the Shares and Warrant Shares by the Company to the Purchasers under the
Transaction Documents. The Company is eligible to register the Shares and the Warrant Shares for
resale by the Purchasers using Form S-1 promulgated under the Securities Act. The Company has not
granted or agreed to grant to any Person any rights (including “piggy-back” registration rights) to
have any securities of the Company registered with the Commission or any other governmental
authority that have not been satisfied or waived. The Company’s Common Stock is registered
pursuant to Section 15(d) of the Exchange Act, and the Company has taken no action designed to, or
which to its knowledge is likely to have the effect of terminating the registration of the Common
Stock under the Exchange Act, nor has the Company received any notification that the Commission is
contemplating terminating such registration.

(y) No Directed Selling Efforts or General Solicitation. Neither the Company, nor any
of its Affiliates, nor any Person acting on its or their behalf has conducted any “general
solicitation” or “general advertising” (as those terms are used in Regulation D) in connection with

(z) No Integrated Offering. Neither the Company nor any of its Affiliates, nor any
Person acting on its or their behalf has, directly or indirectly, at any time within the past six
months made any offers or sales of any Company security or solicited any offers to buy any
security, under circumstances that would (i) eliminate the availability of the exemption from
registration under Regulation D under the Securities Act in connection with the offer and sale by
the Company of the Securities as contemplated hereby or (ii) cause the offering of the Securities
pursuant to the Transaction Documents to be integrated with prior offerings by the Company for
purposes of any applicable law, regulation or stockholder approval provisions, including, without
limitation, under the rules and regulations of any Trading Market.

(aa) Listing and Maintenance Requirements. Except as specified in the SEC Reports,
the Company has not, since April 1, 2005, received notice (written or oral) from any Trading Market
on which the Common Stock is or has been listed or quoted to the effect that the Company is not in
compliance with the listing or maintenance requirements thereof. The Company is in compliance in
all material respects with the listing and maintenance requirements for continued listing of the
Common Stock on the Trading Market on which the Common Stock is currently listed or quoted.

(bb) Investment Company. Neither the Company nor the Subsidiary is required to be
registered as, and is not an Affiliate of, and immediately following the Closing will not be
required to register as, an “investment company” within the meaning of the Investment Company Act
of 1940, as amended.

(cc) Questionable Payments. Neither the Company nor the Subsidiary, nor, to the
Company’s Knowledge, directors, officers, employees, agents or other Persons acting on behalf of
the Company or the Subsidiary has, in the course of its actions for, or on behalf of, the Company:

expenses relating to foreign or domestic political activity; (b) made any direct or indirect
unlawful payments to any foreign or domestic governmental officials or employees from corporate
funds; (c) violated in any material respect any provision of the Foreign Corrupt Practices Act of
1977, as amended or (d) made any other unlawful bribe, rebate, payoff, influence payment, kickback
or other unlawful payment to any foreign or domestic government official or employee.

(dd) Application of Takeover Protections. Except as described in the SEC Reports,
there is no control share acquisition, business combination, poison pill (including any
distribution under a rights agreement) or other similar anti-takeover provision under the Company’s
charter documents or the laws of its state of incorporation that is or could reasonably be expected
to become applicable to any of the Purchasers as a result of the Purchasers and the Company
fulfilling their obligations or exercising their rights under the Transaction Documents, including
without limitation the Company’s issuance of the Securities and the Purchasers’ ownership of the
Securities.

(ee) Disclosure. The Company confirms that neither it nor any Person acting on its
behalf has provided any Purchaser or its respective agents or counsel with any information that
constitutes or might constitute material, non-public information except insofar as the existence,
provisions and terms of the Transaction Documents and the proposed transactions hereunder may
constitute such information. The Company understands and confirms that the Purchasers will rely on
the foregoing representations in effecting transactions in securities of the Company. All
disclosure provided to the Purchasers regarding the Company, its business and the transactions
contemplated hereby, furnished by or on behalf of the Company (including the Company’s
representations and warranties set forth in this Agreement) are true and correct in all material
respects and do not contain any untrue statement of a material fact or omit to state any material
fact necessary in order to make the statements made therein, in light of the circumstances under
which they were made, not misleading. To the Company’s Knowledge, no event or circumstance has
occurred or information exists with respect to the Company nor the Subsidiary or its or their
business, properties, operations or financial conditions, which, under applicable law, rule or
regulation, requires public disclosure or announcement by the Company but which has not been so
publicly announced or disclosed.

3.2 Representations and Warranties of the Purchasers. Each Purchaser hereby, for
itself and for no other Purchaser, represents and warrants to the Company and the Placement Agent
as follows:

(a) Organization; Authority. Such Purchaser is an entity duly organized, validly
existing and in good standing under the laws of the jurisdiction of its organization with the
requisite corporate or partnership power and authority to enter into and to consummate the
transactions contemplated by the applicable Transaction Documents and otherwise to carry out its
obligations hereunder and thereunder. The execution, delivery and performance by such Purchaser of
the transactions contemplated by this Agreement has been duly authorized by all necessary corporate
or, if such Purchaser is not a corporation, such partnership, limited liability company or other
applicable like action, on the part of such Purchaser. Each of this Agreement and the Registration
Rights Agreement has been duly executed by such Purchaser, and when delivered by such Purchaser in
accordance with terms hereof, will constitute the valid and legally binding obligation of such
Purchaser, enforceable against it in accordance with its terms, except as such enforceability may
be limited by applicable bankruptcy, insolvency, reorganization, moratorium, liquidation or similar
laws relating to, or affecting generally the enforcement of, creditors’ rights and remedies or by
other equitable principles of general application.

(b) Investment Intent. Such Purchaser understands that the Securities are “restricted
securities” and have not been registered under the Securities Act or any applicable state
securities law and is acquiring the Securities and, upon exercise of the Warrants will acquire the
Warrant Shares issuable upon exercise thereof, as principal for its own account for investment
purposes only and not with a view to or for distributing or reselling such Securities or any part
thereof, without prejudice, however, to such Purchaser’s right, subject to the provisions of this
Agreement and the Registration Rights Agreement, at all times to sell or otherwise dispose of all
or any part of such Shares or Warrant Shares pursuant to an effective registration statement under
the Securities Act or under an exemption from such registration and in compliance with applicable
federal and state securities laws. Subject to the immediately preceding sentence, nothing
contained herein shall be deemed a representation or warranty by such Purchaser to hold the
Securities for any period of time. Such Purchaser is acquiring the Securities hereunder in the
ordinary course of its business. Such Purchaser does not have any agreement, plan or understanding,
directly or indirectly, with any Person to distribute any of the Securities.

(c) Purchaser Status. At the time such Purchaser was offered the Securities, it was,
and at the date hereof it is, and on each date on which it exercises the Warrants it will be, an
“accredited investor” as defined in Rule 501(a) under the Securities Act. Such Purchaser is not a
registered broker-dealer under Section 15 of the Exchange Act.

(d) Experience of Such Purchaser. Such Purchaser, either alone or together with its
representatives, has such knowledge, sophistication and experience in business and financial
matters so as to be capable of evaluating the merits and risks of the prospective investment in the
Securities, and has so evaluated the merits and risks of such investment. Such Purchaser is able
to bear the economic risk of an investment in the Securities and, at the present time, is able to
afford a complete loss of such investment.

(e) Access to Information. Such Purchaser acknowledges that it reviewed the
Disclosure Materials and has been afforded (i) the opportunity to ask such questions as it has
deemed necessary of, and to receive answers from, representatives of the Company concerning the
terms and conditions of the offering of the Securities and the merits and risks of investing in the
Securities; (ii) access to information (other than material non-public information) about the
Company and the Subsidiary and their respective financial condition, results of operations,
business, properties, management and prospects sufficient to enable it to evaluate its investment;
and (iii) the opportunity to obtain such additional information that the Company possesses or can
acquire without unreasonable effort or expense that is necessary to make an informed investment
decision with respect to the investment. Neither such inquiries nor any other investigation
conducted by or on behalf of such Purchaser or its representatives or counsel shall modify, amend
or affect such Purchaser’s right to rely on the truth, accuracy and completeness of the Disclosure
Materials and the Company’s representations and warranties contained in the Transaction Documents.

(f) Residency. Such Purchaser has, if an entity, its principal place of business or,
if an individual, its primary residence in the jurisdiction set forth immediately below such
Purchaser’s name on the signature pages hereto.

(g) Prohibited Trading Activities. Since the earlier to occur of (1) the time that
such Purchaser was first contacted by the Company, the Placement Agent or any other Person
regarding an investment in the Company and (2) the 10th Trading Day prior to the date of
this Agreement, neither the Purchaser nor any Affiliate of such Purchaser which (x) had knowledge
of the transactions contemplated hereby, (y) has or shares discretion relating to such Purchaser’s
investments or trading or information concerning such Purchaser’s investments, including in respect
of the Securities, or (z) is subject to such Purchaser’s review or input concerning such
Affiliate’s investments or trading (collectively, “Trading Affiliates”) has directly or
indirectly, nor has any Person acting on behalf of or pursuant to any understanding with such
Purchaser or Trading Affiliate, effected or agreed to effect any transactions in the securities of
the Company (including, without limitation, any Short Sales involving the Company’s securities)
(each, a “Prohibited Transaction”). Such Purchaser shall not, and shall cause its Trading
Affiliates not to, engage, directly or indirectly, in a Prohibited Transaction or in any financial
transaction that in any way changes the Purchaser’s or its Trading Affiliates’ economic position in
the Company during the period from the date hereof until the earlier to occur of (i) the
Effectiveness Deadline or (ii) the Effectiveness Date. Each Purchaser agrees that it will not use
any of the Shares or Warrant Shares acquired pursuant to this Agreement to cover any short position
in the Common Stock if doing so would be in violation of applicable securities laws. Each
Purchaser acknowledges that it is aware that the Commission has published its position that
covering a short position established prior to effectiveness of a resale registration statement
with shares included in such registration statement would be a violation of Section 5 of the
Securities Act.

(h) Brokers and Finders. No Person will have, as a result of the transactions
contemplated by this Agreement, any valid right, interest or claim against or upon the Company, or
any Purchaser for any commission, fee or other compensation pursuant to any agreement, arrangement
or understanding entered into by or on behalf of the Purchaser.

(i) Limited Ownership. The purchase by such Purchaser of the Securities issuable to
it at the Closing will not result in such Purchaser (individually or together with other Person
with whom such Purchaser has identified, or will have identified, itself as part of a “group” in a
public filing made with the Commission involving the Company’s securities) acquiring, or obtaining
the right to acquire, in excess of 19.99% of the outstanding shares of Common Stock or the voting
power of the Company on a post transaction basis that assumes that the Closing shall have occurred.
Such Purchaser does not presently intend to, alone or together with others, make a public filing
with the Commission to disclose that it has (or that it together with such other Persons have)
acquired, or obtained the right to acquire, as a result of the Closing (when added to any other
securities of the Company that it or they then own or have the right to acquire), in excess of
19.99% of the outstanding shares of Common Stock or the voting power of the Company on a post
transaction basis that assumes that the Closing shall have occurred.

(j) Independent Investment Decision. Such Purchaser has independently evaluated the
merits of its decision to purchase Securities pursuant to the Transaction Documents, and such
Purchaser confirms that it has not relied on the advice of any other Purchaser’s business and/or
legal counsel in making such decision. Such Purchaser understands that nothing in this Agreement
or any other materials presented by or on behalf of the Company to the Purchaser in connection with
the purchase of the Securities constitutes legal, tax or investment advice. Such Purchaser 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 the Securities. Such Purchaser
understands that the Placement Agent has acted solely as the agent of the Company in this placement
of the Securities and such Purchaser has not relied on the business or legal advice of the
Placement Agent or any of its agents, counsel or Affiliates in making its investment decision
hereunder, and confirms that none of such Persons has made any representations or warranties to
such Purchaser in connection with the transactions contemplated by the Transaction Documents.

The Company acknowledges and agrees that no Purchaser has made or makes any representations or
warranties with respect to the transactions contemplated hereby other than those specifically set
forth in this Section 3.2.

ARTICLE IV.

OTHER AGREEMENTS OF THE PARTIES

4.1 (a) Compliance with Laws. Notwithstanding any other provision of this Article IV,
each Purchaser covenants that the Securities may only be disposed of pursuant to an effective
registration statement under, and in compliance with the requirements of, the Securities Act, or
pursuant to an available exemption from, or in a transaction not subject to, the registration
requirements of the Securities Act, and in compliance with any applicable state and federal
securities laws. In connection with any transfer of the Securities other than pursuant to an
effective registration statement, pursuant to Rule 144(k) or in connection with a pledge as
contemplated in Section 4.1(b), except as otherwise provided herein, the transferor will provide to
the Company an opinion of counsel selected by the transferor, which counsel and the form and
substance of which opinion shall be reasonably satisfactory to the Company and its legal counsel,
to the effect that such transfer does not require registration of such transferred Securities under
the Securities Act. Notwithstanding the foregoing, the Company hereby consents to and agrees to
register on the books of the Company and with its transfer agent, without any such legal opinion,
except to the extent that the transfer agent requests such legal opinion, any transfer of
Securities by a Purchaser to an Affiliate of such Purchaser, provided that the transferee agrees to
the terms and conditions of the Securities, certifies to the Company that it is an “accredited
investor” as defined in Rule 501(a) under the Securities Act and provided that such Affiliate does
not request any removal of any existing legends on any certificate evidencing the Securities.

(b) Legends. Certificates evidencing the Securities will contain the following
legend, until such time as they are not required under Section 4.1(c):

NEITHER THESE SECURITIES NOR THE SECURITIES ISSUABLE UPON EXERCISE OF THESE
SECURITIES HAVE BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE
SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION
UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND,
ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION
STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN
A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND
IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS OR BLUE SKY LAWS.

The Company acknowledges and agrees that a Purchaser may from time to time pledge, and/or
grant a security interest in some or all of the legended Securities, in compliance with applicable
securities laws, pursuant to a bona fide margin agreement in connection with a bona fide margin
loan. Such a pledge would not be subject to approval or consent of the Company and no legal
opinion of legal counsel to the pledgee, secured party or pledgor shall be required in connection
with the pledge, but such legal opinion shall be required in connection with a subsequent transfer
or foreclosure following default by the Purchaser transferee of the pledge. No notice shall be
required of such pledge but Purchaser’s transferee shall promptly notify the Company of the pledge.
Each Purchaser acknowledges that the Company shall not be responsible for any pledges relating to,
or the grant of any security interest in, any of the Securities or for any agreement, understanding
or arrangement between any Purchaser and its pledgee or secured party. Provided that the Company
is in compliance with the terms of this Section 4.1(b), the Company’s indemnification obligations
pursuant to this Agreement shall not extend to any Proceeding or Losses arising out of or related
to this Section 4.1(b).

(c) Removal of Legends. The Company agrees to reissue certificates representing any
of the Shares or Warrant Shares, without the legend set forth above (i) while a registration
statement (including the Registration Statement) covering the resale of such Securities is
effective under the Securities Act, (ii) following any sale of such Securities pursuant to Rule 144
(assuming the transferor is not an affiliate of the Company), (iii) if such Securities are eligible
for sale under Rule 144(k) (to the extent that the applicable Purchaser provides a certification or
legal opinion to the Company to that effect), or (iv) if such legend is not required under
applicable requirements of the Securities Act (including controlling judicial interpretations and
pronouncements issued by the Commission). The Company shall cause its counsel to issue the legal
opinion referred to in the Transfer Agent Instructions to the Company’s transfer agent on the
Effective Date. Following the Effective Date or at such earlier time as a legend is no longer
required for certain Securities, the Company will no later than three Trading Days following the
delivery to the Transfer Agent with notice to the Company of a legended certificate representing
such Securities and a reasonably acceptable opinion of counsel to the extent required by Section
4.1(a), reissue a certificate representing such Securities that is free from all restrictive and
other legends. The Company may not make any notation on its records or give instructions to the
Transfer Agent that enlarge the restrictions on transfer set forth in this Section.

(d) Acknowledgement. Each Purchaser hereunder acknowledges its primary
responsibilities under the Securities Act and accordingly will not sell the Shares, the Warrant
Shares or any interest therein without complying with the requirements of the Securities Act.
While the above-referenced registration statement remains effective, each Purchaser hereunder may
sell the shares in accordance with the plan of distribution contained in the registration statement
and if it does so it will comply therewith and with the related prospectus delivery requirements.
To provide further assurance in connection with de-legending, each Purchaser hereunder commits that
it will continue to hold the shares in its own name, and not in the name of a nominee, until such
time as the shares are duly and properly sold in compliance with all relevant securities laws.
Both the Company and its transfer agent, and their respective directors, officers, employees and
agents, may rely on this subsection (d) and each Purchaser hereunder will indemnify and hold
harmless each of such persons from any breaches or violations of this paragraph.

(e) Buy-In. If within three (3) Trading Days after the Company’s receipt of a
legended certificate representing such Securities the Company shall fail to issue and deliver to
such Purchaser a certificate representing such Securities that is free from all restrictive and
other legends, and if on or after such Trading Day the Purchaser purchases (in an open market
transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the
Purchaser of shares of Common Stock that the Purchaser anticipated receiving from the Company
without any restrictive legend (a “Buy-In”), then the Company shall, within three (3)
Trading Days after the Purchaser’s request and in the Purchaser’s sole discretion, either (i) pay
cash to the Purchaser in an amount equal to the Purchaser’s total purchase price (including
brokerage commissions, if any) for the shares of Common Stock so purchased (the “Buy-In
Price”), at which point the Company’s obligation to deliver such certificate shall terminate
and such shares shall be cancelled, or (ii) promptly honor its obligation to deliver to the
Purchaser a certificate or certificates representing such shares of Common Stock and pay cash to
the Purchaser in an amount equal to the excess (if any) of the Buy-In Price over the product of (a)
such number of shares of Common Stock, times (b) the closing bid price on the date of delivery of
such legended certificate.

4.2 Reservation of Common Stock. The Company shall maintain a reserve from its duly
authorized shares of Common Stock for issuance pursuant to the Transaction Documents in such amount
as may be required to fulfill its obligations in full under the Transaction Documents. In the
event that at any time the then authorized shares of Common Stock are insufficient for the Company
to satisfy its obligations in full under the Transaction Documents, the Company shall promptly take
such actions as may be required to increase the number of authorized shares.

4.3 Furnishing of Information. As long as any Purchaser owns the Securities, the
Company covenants to timely file (or obtain extensions in respect thereof and file within the
applicable grace period) all reports required to be filed by the Company after the date hereof
pursuant to the Exchange Act. As long as any Purchaser owns Securities, if the Company is not
required to file reports pursuant to such laws, it will prepare and furnish to the Purchasers and
make publicly available in accordance with Rule 144(c) such information as is required for the
Purchasers to sell the Shares and Warrant Shares under Rule 144. The Company further covenants
that it will take such further action as any holder of Securities may reasonably request, all to
the extent required from time to time to enable such Person to sell the Shares and Warrant Shares
without registration under the Securities Act within the limitation of the exemptions provided by
Rule 144.

4.4 No Integration. The Company shall not, and shall use its best efforts to ensure
that no Affiliate of the Company shall, sell, offer for sale or solicit offers to buy or otherwise
negotiate in respect of any security (as defined in Section 2 of the Securities Act) that will be
integrated with the offer or sale of the Securities in a manner that would require the registration
under the Securities Act of the sale of the Securities to the Purchasers, or that will be
integrated with the offer or sale of the Securities for purposes of the rules and regulations of
any Trading Market.

4.5 Subsequent Registrations. Other than pursuant to the Registration Statement,
prior to the date occurring sixty (60) days after the Effective Date, the Company shall not file
any registration statement (other than on Form S-4 or S-8) with the Commission with respect to any
securities of the Company, except to the extent the Company becomes eligible to use Form S-3 and
converts the Registration Statement to a Form S-3.

4.6 Securities Laws Disclosure; Publicity. By 9:30 a.m. (New York City time) on the
Trading Day immediately following execution of this Agreement, the Company shall issue a press
release reasonably acceptable to the Placement Agent disclosing all material terms of the
transactions contemplated hereby. No later than the fourth trading day following the Closing Date,
the Company will file a Current Report on Form 8-K with the Commission (the “8-K Filing”)
describing the terms of the transactions contemplated by the Transaction Documents and including as
exhibits to such Current Report on Form 8-K this agreement and the form of Warrant, in the form
required by the Exchange Act. Thereafter, the Company shall timely file any filings and notices
required by the Commission or applicable law with respect to the transactions contemplated hereby
and provide copies thereof to the Purchasers promptly after filing. Notwithstanding the foregoing,
the Company shall not publicly disclose the name of any Purchaser, or include the name of any
Purchaser in any press release or filing with the Commission (other than the Registration
Statement) or any regulatory agency or Trading Market, without the prior written consent of such
Purchaser, except to the extent such disclosure is required by law or Trading Market regulations,
in which case the Company shall promptly provide the Purchasers with prior notice of such
disclosure.

4.7 Indemnification.

(a) Indemnification of Purchasers. In addition to the indemnity provided in the
Registration Rights Agreement, the Company will indemnify and hold the Purchasers and their
directors, officers, shareholders, partners, employees and agents (each, a “Purchaser
Party”) harmless from any and all losses, liabilities, obligations, claims, contingencies,
damages, costs and expenses, including all judgments, amounts paid in settlements, court costs and
reasonable attorneys’ fees and costs of investigation (collectively, “Losses”) that any
such Purchaser Party may suffer or incur as a result of or relating to any material
misrepresentation, breach or inaccuracy of any representation, warranty, covenant or agreement made
by the Company in any Transaction Document. In addition to the indemnity contained herein, the
Company will reimburse each Purchaser Party for its reasonable legal and other expenses (including
the cost of any investigation, preparation and travel in connection therewith) incurred in
connection therewith, as such expenses are incurred. If and to the extent that such indemnification
is unenforceable for any reason, the Company shall make the maximum contribution to the payment and
satisfaction of such losses permissible under applicable law.

(b) Conduct of Indemnification Proceedings. Promptly after receipt by any Person (the
“Indemnified Person”) of notice of any demand, claim or circumstances which would or might
give rise to a claim or the commencement of any action, proceeding or investigation in respect of
which indemnity may be sought pursuant to Section 4.7(a), such Indemnified Person shall
promptly notify the Company in writing and the Company shall assume the defense thereof, including
the employment of counsel reasonably satisfactory to such Indemnified Person, and shall assume the
payment of all fees and expenses; provided, however, that the failure of any
Indemnified Person so to notify the Company shall not relieve the Company of its obligations
hereunder except to the extent that the Company is actually and materially prejudiced by such
failure to notify. In any such proceeding, any Indemnified Person shall have the right to retain
its own counsel, but the fees and expenses of such counsel shall be at the expense of such
Indemnified Person unless: (i) the Company and the Indemnified Person shall have mutually agreed to
the retention of such counsel; or (ii) in the reasonable judgment of counsel to such Indemnified
Person representation of both parties by the same counsel would be inappropriate due to actual or
potential differing interests between them. The Company shall not be liable for any settlement of
any proceeding effected without its written consent, which consent shall not be unreasonably
withheld, delayed or conditions, but if settled without such consent, or if there be a final
judgment for the plaintiff, the Company shall indemnify and hold harmless such Indemnified Person
from and against any Losses by reason of such settlement or judgment. Without the prior written
consent of the Indemnified Person, the Company shall not effect any settlement of any pending or
threatened proceeding in respect of which any Indemnified Person is or could have been a party and
indemnity could have been sought hereunder by such Indemnified Party, unless such settlement
includes an unconditional release of such Indemnified Person from all liability arising out of such
proceeding.

4.8 Non-Public Information. The Company covenants and agrees that neither it nor any
other Person acting on its behalf will provide or has provided any Purchaser or its agents or
counsel with any information that the Company believes constitutes material non-public information
(other than (i) the contemplated Transaction Documents and the transactions contemplated thereby
and (ii) certain financial information related to the Company, in exchange for the receipt of
which, such Purchaser has entered into a written agreement regarding the confidentiality and use of
such information ), unless prior thereto such Purchaser shall have executed a written agreement
regarding the confidentiality and use of such information. The Company understands and confirms
that each Purchaser shall be relying on the foregoing representations in effecting transactions in
securities of the Company.

4.9 Listing of Securities. Promptly following the date hereof, the Company shall take
all necessary action to cause the Shares, the Warrant Shares and the shares of Common Stock
issuable upon exercise of the Placement Agent Warrants to be approved for inclusion in the Trading
Market. In furtherance thereof, as soon as practicable after the Effectiveness Date, the Company
shall use its commercially reasonable efforts to take such actions as may be necessary to file with
the American Stock Exchange an application or other document required by the American Stock
Exchange and pay all applicable fees for the listing of the Shares, the Warrant Shares and the
shares of Common Stock issuable upon exercise of the Placement Agent Warrants and will take such
other action as is necessary to cause such Common Stock to be so listed. The Company will use
commercially reasonable efforts to continue the listing and trading of its Common Stock on the
American Stock Exchange and, in accordance, therewith, will use commercially reasonable efforts to
comply in all respects with the Company’s reporting, filing and other obligations applicable to
issuers whose securities are listed on such market.

4.10 Use of Proceeds. The Company intends to use the net proceeds from the sale of
the Securities hereunder for working capital and general corporate purposes and not to redeem any
Common Stock or Common Stock Equivalents or to settle any outstanding Action.

4.11 Limitation on Acquisition of Shares. On and after the Closing Date and for so
long as any Warrant remains outstanding, no Purchaser will acquire securities of the Company such
that it becomes the beneficial owner (as defined under Section 13 of the Exchange Act) of more than
9.99% of the outstanding shares of Common Stock.

the parties with respect to the subject matter hereof and supersede all prior agreements,

6.4 Amendments; Waivers; No Additional Consideration. No provision of this Agreement
may be waived or amended except in a written instrument signed, in the case of an amendment, by the
Company and each of the Purchasers or, in the case of a waiver, by the party against whom
enforcement of any such waiver is sought. No waiver of any default with respect to any provision,
condition or requirement of this Agreement shall be deemed to be a continuing waiver in the future
or a waiver of any subsequent default or a waiver of any other provision, condition or requirement
hereof, nor shall any delay or omission of either party to exercise any right hereunder in any
manner impair the exercise of any such right. No consideration shall be offered or paid to any
Purchaser to amend or consent to a waiver or modification of any provision of any Transaction
Document unless the same consideration is also offered to all Purchasers who then hold Shares.

6.5 Construction. The headings herein are for convenience only, do not constitute a
part of this Agreement and shall not be deemed to limit or affect any of the provisions hereof.
The language used in this Agreement will be deemed to be the language chosen by the parties to
express their mutual intent, and no rules of strict construction will be applied against any party.
This Agreement shall be construed as if drafted jointly by the parties, and no presumption or
burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any
provisions of this Agreement or any of the Transaction Documents.

6.6 Successors and Assigns. The provisions of this Agreement shall inure to the
benefit of and be binding upon the parties and their successors and permitted assigns. This
Agreement, or any rights or obligations hereunder, may not be assigned by the Company without the
prior written consent of the Purchasers. Any Purchaser may assign its rights hereunder in whole or
in part to any Person to whom such Purchaser assigns or transfers any Securities in compliance with
this Agreement and applicable law, provided such transferee shall agree in writing to be bound,
with respect to the transferred Securities, by the terms and conditions of this Agreement that
apply to the “Purchasers.”

6.7 No Third-Party Beneficiaries. This Agreement is intended for the benefit of the
parties hereto and their respective successors and permitted assigns and is not for the benefit of,
nor may any provision hereof be enforced by, any other Person, except each Purchaser Party is an
intended third party beneficiary of Section 4.7 and may enforce the provisions of such Section
directly against the parties with obligations thereunder .

6.8 Governing Law. All questions concerning the construction, validity, enforcement
and interpretation of this Agreement shall be governed by and construed and enforced in accordance
with the internal laws of the State of California, without regard to the principles of conflicts of
law thereof. Nothing contained herein shall be deemed to limit in any way any right to serve
process in any manner permitted by law. Each party hereto hereby irrevocably waives, to the
fullest extent permitted by applicable law, any and all right to trial by jury in any legal
proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.
If either party shall commence a Proceeding to enforce any provisions of a Transaction Document,
then the prevailing party in such Proceeding shall be reimbursed by the other party for its
reasonable attorney’s fees and other costs and expenses incurred with the investigation,
preparation and prosecution of such Proceeding.

6.9 Survival. Subject to applicable statute of limitations, the representations,
warranties, agreements and covenants contained herein shall survive the Closing and the delivery of
the Securities.

6.10 Execution. This Agreement may be executed in two or more counterparts, all of
which when taken together shall be considered one and the same agreement and shall become effective
when counterparts have been signed by each party and delivered to the other party, it being
understood that both parties need not sign the same counterpart. In the event that any signature
is delivered by facsimile transmission, such signature shall create a valid and binding obligation
of the party executing (or on whose behalf such signature is executed) with the same force and
effect as if such facsimile signature page were an original thereof.

6.11 Severability. If any provision of this Agreement is held to be invalid or
unenforceable in any respect, the validity and enforceability of the remaining terms and provisions
of this Agreement shall not in any way be affected or impaired thereby and the parties will attempt
to agree upon a valid and enforceable provision that is a reasonable substitute therefor, and upon
so agreeing, shall incorporate such substitute provision in this Agreement.

6.12 Replacement of Securities. If any certificate or instrument evidencing any
Securities is mutilated, lost, stolen or destroyed, the Company shall issue or cause to be issued
in exchange and substitution for and upon cancellation thereof, or in lieu of and substitution
therefor, a new certificate or instrument, but only upon receipt of evidence reasonably
satisfactory to the Company of such loss, theft or destruction and the execution by the holder
thereof of a customary lost certificate affidavit of that fact and an agreement to indemnify and
hold harmless the Company for any losses in connection therewith. The applicants for a new
certificate or instrument under such circumstances shall also pay any reasonable third-party costs
associated with the issuance of such replacement Securities. If a replacement certificate or
instrument evidencing any Securities is requested due to a mutilation thereof, the Company may
require delivery of such mutilated certificate or instrument as a condition precedent to any
issuance of a replacement.

6.13 Remedies. In addition to being entitled to exercise all rights provided herein
or granted by law, including recovery of damages, each of the Purchasers and the Company will be
entitled to specific performance under the Transaction Documents. The parties agree that monetary
damages may not be adequate compensation for any loss incurred by reason of any breach of
obligations described in the foregoing sentence and hereby agrees to waive in any action for
specific performance of any such obligation (other than in connection with any action for a
temporary restraining order) the defense that a remedy at law would be adequate.

6.14 Payment Set Aside. To the extent that the Company makes a payment or payments to
any Purchaser pursuant to any Transaction Document or a Purchaser enforces or exercises its rights
thereunder, and such payment or payments or the proceeds of such enforcement or exercise or any
part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside,
recovered from, disgorged by or are required to be refunded, repaid or otherwise restored to the
Company, a trustee, receiver or any other person under any law (including, without limitation, any
bankruptcy law, state or federal law, common law or equitable cause of action), then to the extent
of any such restoration the obligation or part thereof originally intended to be satisfied shall be
revived and continued in full force and effect as if such payment had not been made or such
enforcement or setoff had not occurred.

6.15 Independent Nature of Purchasers’ Obligations and Rights. The obligations of
each Purchaser under any Transaction Document are several and not joint with the obligations of any
other Purchaser, and no Purchaser shall be responsible in any way for the performance of the
obligations of any other Purchaser under any Transaction Document. The decision of each Purchaser
to purchase Securities pursuant to the Transaction Documents has been made by such Purchaser
independently of any other Purchaser and independently of any information, materials, statements or
opinions as to the business, affairs, operations, assets, properties, liabilities, results of
operations, condition (financial or otherwise) or prospects of the Company or the Subsidiary which
may have been made or given by any other Purchaser or by any agent or employee of any other
Purchaser, and no Purchaser and any of its agents or employees shall have any liability to any
other Purchaser (or any other Person) relating to or arising from any such information, materials,
statement or opinions. Nothing contained herein or in any Transaction Document, and no action
taken by any Purchaser pursuant thereto, shall be deemed to constitute the Purchasers as a
partnership, an association, a joint venture or any other kind of entity, or create a presumption
that the Purchasers are in any way acting in concert or as a group with respect to such obligations
or the transactions contemplated by the Transaction Documents. Each Purchaser acknowledges that no
other Purchaser has acted as agent for such Purchaser in connection with making its investment
hereunder and that no Purchaser will be acting as agent of such Purchaser in connection with
monitoring its investment in the Securities or enforcing its rights under the Transaction
Documents. Each Purchaser shall be entitled to independently protect and enforce its rights,
including without limitation the rights arising out of this Agreement or out of the other
Transaction Documents, and it shall not be necessary for any other Purchaser to be joined as an
additional party in any proceeding for such purpose. The Company acknowledges that each of the
Purchasers has been provided with the same Transaction Documents for the purpose of closing a
transaction with multiple Purchasers and not because it was required or requested to do so by any
Purchaser.

6.16  Termination. This Agreement may be terminated and the sale and purchase of the
Shares and the Warrants abandoned at any time prior to the Closing by either the Company or any

1

Purchaser (with respect to itself only) upon written notice to the other, if the Closing has
not been consummated on or prior to 5:00 p.m. (Pacific time) on the Outside Date; provided,
however, that the right to terminate this Agreement under this Section 6.16 shall not be available
to any Person whose failure to comply with its obligations under this Agreement has been the cause
of or resulted in the failure of the Closing to occur on or before such time. Nothing in this
Section 6.16 shall be deemed to release any party from any liability for any breach by such party
of the terms and provisions of this Agreement or the other Transaction Documents or to impair the
right of any party to compel specific performance by any other party of its obligations under this
Agreement or the other Transaction Documents.

IN WITNESS WHEREOF, the parties hereto have caused this Securities Purchase Agreement to be
duly executed by their respective authorized signatories as of the date first indicated above.

Certain legal consequences arise from being named as a Selling Shareholder in a Registration
Statement and the related prospectus. Accordingly, beneficial owners of Common Stock and Warrants
are advised to consult their own securities law counsel regarding the consequences of being named
or not being named as a Selling Shareholder in the Registration Statement and the related
prospectus.

The undersigned acknowledges its obligation to comply with the provisions of the Securities
Exchange Act of 1934 and the rules thereunder relating to stock manipulation, particularly
Regulation M thereunder (or any successor rules or regulations), in connection with any offering of
Common Stock pursuant to the Registration Statement. The undersigned agrees that neither it nor
any person acting on its behalf will engage in any transaction in violation of such provisions.

The undersigned hereby acknowledges and is advised of the following Interpretation A.65 of the July
1997 SEC Manual of Publicly Available Telephone Interpretations regarding short selling:

“An Issuer filed a Form S-3 registration statement for a secondary offering of common stock which
is not yet effective. One of the selling shareholders wanted to do a short sale of common stock
“against the box” and cover the short sale with registered shares after the effective date. The
issuer was advised that the short sale could not be made before the registration statement become
effective, because the shares underlying the short sale are deemed to be sold at the time such sale
is

8

made. There would, therefore, be a violation of Section 5 if the shares were effectively
sold prior to the effective date.”

By returning this Questionnaire, the undersigned will be deemed to be aware of the foregoing
interpretation.

Upon any sale of Common Stock pursuant to the Registration Statement, the Selling Securityholder
will be required to deliver to the Transfer Agent (with a copy to the Company) the Notice of
Transfer (completed and signed) in the form attached as Annex A hereto and hereby
undertakes to do so.

In the event that the undersigned transfers all or any portion of the Company’s Common Stock or
Warrants after the date on which the information in this Questionnaire is provided to the Company,
the undersigned agrees to notify the transferee(s) at the time of transfer of its rights and
obligations hereunder.

By signing below, the undersigned consents to the disclosure of the information contained in this
Questionnaire and the inclusion of such information in the Registration Statement, the related
prospectus and any state securities or “Blue Sky” applications. The undersigned understands that
the information in this Questionnaire will be relied upon by the Company in connection with the
preparation or amendment of the Registration Statement or related prospectus.

By signing below, the undersigned represents that the information provided herein is accurate and
complete. The undersigned agrees to promptly notify the Company of any inaccuracies or changes in
the information provided herein that may occur subsequent to the date hereof at any time while the
Registration Statement remains effective.

Once this Questionnaire is executed by the undersigned beneficial holder and received by the
Company, the terms of this Questionnaire, and the representations and warranties contained herein,
shall be binding on, shall inure to the benefit of and shall be enforceable by the respective
successors, heirs, personal representatives and assigns of the Company and shall be governed in all
respects by the internal laws of the State of California.

	 	Re: Clearant, Inc.

Ladies and Gentlemen:

We are counsel to Clearant, Inc., a Delaware corporation (the “Company”), and have represented
the Company in connection with that certain Securities Purchase Agreement, dated as of November 7,
2005, entered into by and among the Company and the buyers named therein (collectively, the
“Purchasers”) pursuant to which the Company issued to the Purchasers shares of the Company’s Common
Stock, par value $0.0001 per share (the “Common Stock”) and warrants exercisable for shares of
Common Stock (the “Warrants”). Pursuant to that certain Registration Rights Agreement of even date,
the Company agreed to register the resale of the Common Stock, including the shares of Common Stock
issuable upon exercise of the Warrants (collectively, the “Registrable Securities”) under the
Securities Act of 1933, as amended (the “Securities Act”). In connection with the Company’s
obligations under the Registration Rights Agreement, on  , 2005, the
Company filed a Registration Statement on Form S-1 (File No. 333- ) (the
“Registration Statement”) with the Securities and Exchange Commission (the “Commission”) relating
to the Registrable Securities which names each of the Purchasers as a selling stockholder
thereunder.

In connection with the foregoing, we advise you that a member of the Commission’s staff has
advised us by telephone that the Commission has entered an order declaring the Registration
Statement effective under the Securities Act at [ENTER TIME OF EFFECTIVENESS] on [ENTER DATE OF
EFFECTIVENESS] and we have no knowledge, after telephonic inquiry of a member of the staff, that
any stop order suspending its effectiveness has been issued or that any proceedings for that
purpose are pending before, or threatened by, the Commission and the Registrable Securities are
available for resale under the Securities Act pursuant to the Registration Statement.

This letter shall serve as our standing notice to you that the Common Stock may be freely
transferred by the Purchasers pursuant to the Registration Statement so long as the Holders certify
they have complied with the prospectus delivery requirements of the Securities Act. You need not
require further letters from us to effect any future legend-free issuance or reissuance of shares
of Common Stock to the transferees of the Purchasers as contemplated by the Company’s Irrevocable
Transfer Agent Instructions dated November     , 2005. This letter shall serve as our standing
instructions with regard to this matter.

Exhibit E

Clearant, Inc.

Form of Legal Opinion of Greenberg Traurig, LLP

Based on the foregoing, and subject to the qualifications and assumptions stated herein, we
are of the opinion that:

1. Each of the Company and the Subsidiary is a corporation validly existing and in good
standing under the laws of the State of Delaware and has all requisite corporate power and
authority to own, lease and operate its properties and to conduct its business as presently being
conducted.

2. Each of the Company and the Subsidiary is duly qualified to transact business and is in
good standing as a foreign corporation in the State of California.

3. The Shares and Warrant Shares to be issued by the Company pursuant to the Agreement have
been duly authorized and reserved, when issued and delivered in the manner contemplated by the
Agreement and the Warrant, respectively, will be validly issued, fully paid and nonassessable, and
free of preemptive rights arising under law or pursuant to the Company’s Certificate of
Incorporation.

4. Assuming the Purchaser acquires the Shares and Warrant being sold to it pursuant to the
Agreement without notice of an adverse claim thereto, upon (a) the delivery to the Purchaser of
such Shares and Warrant, (b) payment by the Purchaser therefor in the manner contemplated by the
Agreement, and (c) the acquisition by the Purchaser of control of such Shares and Warrant, the
Purchaser will acquire such Shares and Warrant free of any adverse claim. For purposes of this
paragraph 5, the terms “delivery,” “control,” “adverse claim” and “notice of an adverse claim” have
the respective meanings assigned to them in Sections 8301, 8106, 810 (a)(1) and 8105 of the
California Commercial Code in effect on the date hereof.

5. The Company has all requisite corporate power and authority to execute and deliver the
Transaction Documents and to perform its obligations thereunder. The execution, delivery and
performance of the Transaction Documents by the Company and the consummation by the Company of the
transactions contemplated thereby have been duly authorized by all requisite corporate action on
the part of the Company.

6. The Agreement has been duly and validly executed and delivered by the Company and (assuming
the due authorization, execution and delivery thereof by the Purchasers) constitutes the legal,
valid and binding obligation of the Company, enforceable against it in accordance with its terms,
subject to applicable bankruptcy, insolvency, fraudulent conveyance, reorganization,
conservatorship, moratorium and similar laws affecting creditors’ rights and remedies generally,
and subject, as to enforceability, to general principles of equity, including principles of
commercial reasonableness, good faith and fair dealing (irrespective of whether enforcement is
sought in a proceeding at law or in equity) and except that (A) rights to indemnification and
contribution thereunder may be limited by federal or state securities laws or public policy
relating thereto, (B) no opinion is expressed herein with respect to Sections 6.7 and 6.8 of the
Agreement and (C) certain remedial provisions of the Agreement are or may be unenforceable in whole
or in part under the laws of the State of California, but the inclusion of such provisions does not
affect the validity of the Agreement.

7. The execution and delivery by the Company of the Agreement, and the performance by the
Company with its obligations thereunder, do not constitute a default under or violate (i) any
provisions of the articles of incorporation or by-laws of the Company presently in effect, (ii) any
of the terms or provisions of any material document, agreement or other instrument to which the
Company is a party or by which it is bound, of which we are aware, (iii) any California, Delaware
corporate or United States federal law or regulation (other than federal and state securities or
“blue sky” laws, as to which we express no opinion in this paragraph 8), or (iv) any judgment,
writ, injunction, decree, order or ruling of any California, Delaware corporate or United States
federal court or public or governmental authority binding on the Company, of which we are aware.

8. No consent, approval, waiver, license or authorization or other action by or filing or
registration with any California, Delaware corporate or United States federal public or
governmental authority is required in connection with the valid execution and delivery by the
Company of the Agreement or the consummation by the Company of the transactions contemplated
thereby, except for filings, registrations and other actions required pursuant to the Securities
Act of 1933, as amended, the Securities Exchange Act of 1934, as amended, and the respective rules
and regulations thereunder; filings by or on behalf of the underwriters with the Corporate
Financing Department of the National Association of Securities Dealers, Inc., filings in connection
with state securities or “blue sky” laws, in each case as to which we express no opinion in this
paragraph 9, and those which already have been obtained by the Company.

9. Except as set forth in the Company’s SEC Reports or as otherwise identified in any
Transaction Document, to our knowledge there is no litigation, proceeding or public or governmental
investigation pending or threatened in writing against the Company that relates to the transactions
contemplated by the Agreement or which, if determined adversely to the Company, would have a
material adverse effect on the business, assets or financial condition of the Company and its
Subsidiaries, considered as an entirety.

10. Our opinion has been requested as to the availability of the exemption from the
registration requirements of Section 5 of the Securities Act of 1933, as amended (the “Securities
Act”), provided by Regulation D thereunder (“Regulation D”), with respect to the sale of the Shares
and Warrants pursuant to the Agreement. Based upon and subject to the following assumptions, we
are of the opinion that the sale of the Shares and the Warrants by the Company complies with the
provisions of Regulation D, and, accordingly, such sale may be effected without registration under
the Act in reliance on Regulation D. We are relying on the representation of the Company contained
in the Agreement as to no general solicitation and the representations of the Purchasers contained
in the Agreement, including without limitation to the effect that the Purchaser (i) is an
“accredited investor” within the meaning of Regulation D under the Securities Act, (ii) has such
knowledge and experience in financial and business matters that the Purchaser is capable of
evaluating the merits and risks of the prospective investment, and (iii) is acquiring the
Securities for its own account, for investment purposes and without a view to distribution. The
Securities are legended to reflect that they have not been registered under the Securities Act or
the securities laws of any state and may not be sold or transferred in the absence of such
registration or an exemption therefrom under the Securities Act and such state securities laws.

Act) and shall contain (except if otherwise required pursuant to written comments received from the

pursuant to Rule 144(k) as determined by the counsel to the Company pursuant to a written opinion

Registration Statement is not declared effective by the Commission on or prior to the Required
Effectiveness Date or (iii) after its Effective Date such Registration Statement ceases for any
reason to be effective and available to the Holders as to all Registrable Securities to which it is
required to cover at any time prior to the expiration of its Effectiveness Period for an aggregate
of more than 30 consecutive Trading Days or an aggregate of 60 Trading Days in any twelve-month
period (which need not be consecutive), (any such failure or breach as to Holders who have timely

addition to any other rights available to the Holders: (x) on such Event Date the Company shall pay
to each Holder an amount in cash, as liquidated damages and not as a penalty, equal to 2.0% of the

each monthly anniversary of each such Event Date thereof (if the applicable Event shall not have
been cured by such date) until the applicable Event is cured, the Company shall pay to each Holder
an amount in cash, as liquidated damages and not as a penalty, equal to 2.0% of the aggregate
Subscription Amount paid by such Holder pursuant to the Purchase Agreement. If the Company fails
to pay any liquidated damages pursuant to this Section in full within seven days after the date
payable, the Company will pay interest thereon at a rate of 10% per annum (or such lesser maximum
amount that is permitted to be paid by applicable law) to the Holder, accruing daily from the date
such liquidated damages are due until such amounts, plus all such interest thereon, are paid in
full. The liquidated damages pursuant to the terms hereof shall apply on a pro-rata basis for any
portion of a month prior to the cure of an Event, except in the case of the first Event Date.

(d) The Company shall not, from the date hereof until the Effective Date of the Registration
Statement, prepare and file with the Commission a registration statement relating to an offering
for its own account or the account of others under the Securities Act of any of its equity
securities other than a registration statement on Form S-8.

3. Registration Procedures

In connection with the Company’s registration obligations hereunder, the Company shall:

(a) (i) Prepare and file with the Commission such amendments, including post-effective
amendments, to each Registration Statement and the Prospectus used in connection therewith as may
be necessary to keep such Registration Statement continuously effective as to the applicable
Registrable Securities for its Effectiveness Period and prepare and file with the Commission such
additional Registration Statements in order to register for resale under the Securities Act all of
the Registrable Securities; (ii) cause the related Prospectus to be amended or supplemented by any
required Prospectus supplement, and as so supplemented or amended to be filed pursuant to Rule 424;
(iii) respond as promptly as reasonably practicable, and in any event within 15 Trading Days to any
comments received from the Commission with respect to each Registration Statement or any amendment
thereto and, as promptly as reasonably possible provide the Holders true and complete copies of all
correspondence from and to the Commission relating to such Registration Statement that pertains to
the Holders as Selling Stockholders but not any comments that would result in the disclosure to the
Holders of material and non-public information concerning the Company; and (iv) comply in all
material respects with the provisions of the Securities Act and the Exchange Act with respect to
the disposition of all Registrable Securities covered by the Registration Statements.

(b) Notify the Holders as promptly as reasonably possible (and, in the case of (i) below, not
less than three Trading Days prior to such filing) and (if requested by any such Person) confirm
such notice in writing no later than one Trading Day thereafter of any of the following events: (i)
a Prospectus or any Prospectus supplement or post-effective amendment to a Registration Statement
is proposed to be filed; (ii) the Commission notifies the Company whether there will be a “review”
of any Registration Statement; (iii) the Commission comments in writing on any Registration
Statement (in which case the Company shall provide true and complete copies thereof and all written
responses thereto to each of the Holders that pertain to the Holders as a Selling Stockholder or to
the Plan of Distribution, but not information which the Company believes would constitute material
and non-public information); (iii) any Registration Statement or any post-effective amendment has
been declared effective; (iv) any request by the Commission or any other Federal or state
governmental authority for amendments or supplements to a Registration Statement or Prospectus or
for additional information that pertains to the Holders as Selling Stockholders or the Plan of
Distribution; (v) the issuance by the Commission of any stop order suspending the effectiveness of
a Registration Statement covering any or all of the Registrable Securities or the initiation of any
Proceedings for that purpose; (vi) the receipt by the Company of any notification with respect to
the suspension of the qualification or exemption from qualification of any of the Registrable
Securities for sale in any jurisdiction, or the initiation or threatening of any Proceeding for
such purpose; and (vii) the occurrence of any event or passage of time that makes the financial
statements included in a Registration Statement ineligible for inclusion therein or any statement
made in such Registration Statement or Prospectus or any document incorporated or deemed to be
incorporated therein by reference untrue in any material respect or that requires any revisions to
such Registration Statement, Prospectus or other documents so that, in the case of such
Registration Statement or the Prospectus, as the case may be, it will not contain any untrue
statement of a material fact or omit to state any material fact required to be stated therein or
necessary to make the statements therein (in the case of any Prospectus, form of prospectus or
supplement thereto, in light of the circumstances under which they were made), not misleading.

(c) Use its reasonable best efforts to avoid the issuance of, or, if issued, obtain the
withdrawal of (i) any order suspending the effectiveness of a Registration Statement, or (ii) any
suspension of the qualification (or exemption from qualification) of any of the Registrable
Securities for sale in any jurisdiction, as soon as practicable.

(d) If requested by a Holder, furnish to such Holder, without charge, at least one conformed
copy of each Registration Statement and each amendment thereto and all exhibits to the extent
requested by such Person (including those previously furnished or incorporated by reference)
promptly after the filing of such documents with the Commission; provided, that the Company shall
have no obligation to provide any document pursuant to this clause that is available on the EDGAR
system.

(e) Promptly deliver to each Holder, without charge, as many copies of each Prospectus or
Prospectuses (including each form of prospectus) and each amendment or supplement thereto as such
Persons may reasonably request. The Company hereby consents to the use of such Prospectus and each
amendment or supplement thereto by each of the selling Holders in connection with the offering and
sale of the Registrable Securities covered by such Prospectus and any amendment or supplement
thereto to the extent permitted by federal and state securities laws and regulations.

(f) Prior to any public offering of Registrable Securities, use its reasonable best efforts to
register or qualify or cooperate with the selling Holders in connection with the registration or
qualification (or exemption from such registration or qualification) of such Registrable Securities
for offer and sale under the securities or Blue Sky laws of those jurisdictions within the United
States as any Holder requests in writing, to keep each such registration or qualification (or
exemption therefrom) effective during the Effectiveness Period and to do any and all other acts or
things necessary or advisable to enable the disposition in such jurisdictions of the Registrable
Securities covered by the Registration Statements; provided, that the Company shall not be required
to qualify generally to do business in any jurisdiction where it is not then so qualified or to
take any action that would subject the Company to general service of process in any jurisdiction
where it is not then so subject or subject the Company to any material tax in any such jurisdiction
where it is not then so subject.

(g) Cooperate with the Holders to facilitate the timely preparation and delivery of
certificates representing Registrable Securities to be delivered to a transferee pursuant to the
Registration Statements, which certificates shall be free, to the extent permitted by the Purchase
Agreement and under law, of all restrictive legends, and to enable such Registrable Securities to
be in such denominations and registered in such names as any such Holders may reasonably request.
In connection therewith, if required by the Company’s transfer agent, the Company shall promptly
after the effectiveness of the Registration Statement cause an opinion of counsel as to the
effectiveness of the Registration Statement to be delivered to and maintained with its transfer
agent, together with any other authorizations, certificates and directions required by the transfer
agent, which authorize and direct the transfer agent to issue such Registrable Securities without
legend upon sale by the holder of such shares of Registrable Securities under the Registration
Statement.

(h) Following the occurrence of any event contemplated by Section 3(c)(vii), as promptly as
reasonably possible, prepare a supplement or amendment, including a post-effective amendment, to
the affected Registration Statements or a supplement to the related Prospectus or any document
incorporated or deemed to be incorporated therein by reference, and file any other required
document so that, as thereafter delivered, no Registration Statement nor any Prospectus will
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 the case of any Prospectus, form of
prospectus or supplement thereto, in light of the circumstances under which they were made), not
misleading.

(i) (i) In the time and manner required by each Trading Market, prepare and file with such
Trading Market an additional shares listing application covering all of the Registrable Securities,
(ii) take all steps necessary to cause such Registrable Securities to be approved for listing on
each Trading Market as soon as possible thereafter, (iii) provide the Holders evidence of such
listing, and (iv) except as a result of the Excluded Events, during the Effectiveness Period,
maintain the listing of such Registrable Securities on each such Trading Market.

(j) Until the end of the Effectiveness Period, the Company covenants to (a) timely file (or
obtain extensions in respect thereof and file within the applicable grace period) all reports
required to be filed by the Company after the date hereof pursuant to Section 13(a) or 15(d) of the
Exchange Act, or (b) prepare and furnish to the Holders and make other public information available
in accordance with Rule 144(c), and (c) take such further action as any Holder may reasonably
request, to the extent required from time to time to enable such Person to sell Shares and Warrant
Shares without registration under the Securities Act within the limitation of the exemptions
provided by Rule 144, including compliance with the provisions of the Purchase Agreement relating
to the transfer of the Shares and Warrant Shares.

(k) The Company may require each selling Holder to furnish to the Company a current Selling
Holder Questionnaire, including a certified statement as to the number of shares of Common Stock
beneficially owned by such Holder and any Affiliate thereof. The Company shall not file a
Registration Statement, any Prospectus or any amendments or supplements thereto in which the
“Selling Stockholder” section thereof differs from the disclosure received from a Holder in its
Selling Holder Questionnaire (as then amended or supplemented), except as may otherwise be required
by applicable securities law or the Commission

4. Registration Expenses. All fees and expenses incident to the Company’s performance
of or compliance with its obligations under this Agreement (excluding any underwriting discounts
and selling commissions and all legal fees and expenses of legal counsel for any Holder) shall be
borne by the Company whether or not any Registrable Securities are sold pursuant to a Registration
Statement. The fees and expenses referred to in the foregoing sentence shall include, without
limitation, (i) all registration and filing fees (including, without limitation, fees and expenses
(A) with respect to filings required to be made with the Trading Market on which the Common Stock
is then listed for trading, and (B) in compliance with applicable state securities or Blue Sky
laws), (ii) printing expenses (including, without limitation, expenses of printing certificates for
Registrable Securities and of printing prospectuses if the printing of prospectuses is reasonably
requested by the holders of a majority of the Registrable Securities included in the Registration
Statement), (iii) messenger, telephone and delivery expenses, (iv) fees and disbursements of
counsel for the Company, (v) Securities Act liability insurance, if the Company so desires such
insurance, and (vi) fees and expenses of all other Persons retained by the Company in connection
with the consummation of the transactions contemplated by this Agreement. In addition, the Company
shall be responsible for all of its internal expenses incurred in connection with the consummation
of the transactions contemplated by this Agreement (including, without limitation, all salaries and
expenses of its officers and employees performing legal or accounting duties), the expense of any
annual audit and the fees and expenses incurred in connection with the listing of the Registrable
Securities on any securities exchange as required hereunder. In no event shall the Company be
responsible for any broker or similar commissions or any legal fees or other costs of the Holders.

5. Indemnification.

(a) Indemnification by the Company. The Company shall, notwithstanding any
termination of this Agreement, indemnify and hold harmless each Holder, the officers, directors,
agents, partners, members, shareholders and employees of each of them, each Person who controls any
such Holder (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange
Act) and the officers, directors, agents and employees of each such controlling Person, to the
fullest extent permitted by applicable law, from and against any and all losses, claims, damages,
liabilities, costs (including, without limitation, reasonable costs of preparation and reasonable
attorneys’ fees) and expenses (collectively, “Losses”), as incurred, arising out of or relating to
(i) any untrue or alleged untrue statement of a material fact contained in any Registration
Statement, any Prospectus or any form of prospectus or in any amendment or supplement thereto (it
being understood that the Holder has approved Annex A hereto for this purpose) or in any
preliminary prospectus, or arising out of or relating to any omission or alleged omission of a
material fact required to be stated therein or necessary to make the statements therein (in the
case of any Prospectus or form of prospectus or supplement thereto, in light of the circumstances
under which they were made) not misleading, except to the extent, but only to the extent, that (A)
such untrue statements, alleged untrue statements, omissions or alleged omissions are based solely
upon information regarding such Holder furnished in writing to the Company by such Holder expressly
for use therein, or to the extent that such information relates to such Holder or such Holder’s
proposed method of distribution of Registrable Securities and was reviewed and expressly approved
in writing by such Holder expressly for use in the Registration Statement, such Prospectus or such
form of Prospectus or in any amendment or supplement thereto (it being understood that the Holder
has approved Annex A hereto for this purpose) or (2) in the case of an occurrence of an event of
the type specified in Section 3(c)(iv)-(vii), the use by such Holder of an outdated or defective
Prospectus after the Company has notified such Holder in writing that the Prospectus is outdated or
defective and prior to the receipt by such Holder of an Advice (as defined in Section 6(d) below)
or an amended or supplemented Prospectus, but only if and to the extent that following the receipt
of the Advice or the amended or supplemented Prospectus the misstatement or omission giving rise to
such Loss would have been corrected; provided, however, that the indemnity agreement contained in
this Section 5(b) shall not apply to amounts paid in settlement of any Losses if such settlement is
effected without the prior written consent of the Holder, which consent shall not be unreasonably
withheld.] The Company shall notify the Holders promptly of the institution, threat or assertion
of any Proceeding of which the Company is aware in connection with the transactions contemplated by
this Agreement. Such indemnity shall remain in full force and effect regardless of any
investigation made by or on behalf of an Indemnified Party (as defined in Section 5(c)) and shall
survive the transfer of the Registrable Securities by the Holders.

(b) Indemnification by Holders. Each Holder shall, notwithstanding any termination of
this Agreement, severally and not jointly, indemnify and hold harmless the Company, its directors,
officers, agents and employees, each Person who controls the Company (within the meaning of Section
15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers, agents
or employees of such controlling Persons, to the fullest extent permitted by applicable law, from
and against all Losses, as incurred, arising solely out of or based solely upon: (x) such Holder’s
failure to comply with the prospectus delivery requirements of the Securities Act or (y) any untrue
statement of a material fact contained in any Registration Statement, any Prospectus, or any form
of prospectus, or in any amendment or supplement thereto, or arising solely out of or based solely
upon any omission of a material fact required to be stated therein or necessary to make the
statements therein (in the case of any Prospectus, or any form of prospectus or supplement thereto,
in light of the circumstances under which they were made) not misleading to the extent, but only to
the extent that, (A) such untrue statements or omissions are based solely upon information
regarding such Holder furnished in writing to the Company by such Holder expressly for use therein,
or to the extent that such information relates to such Holder or such Holder’s proposed method of
distribution of Registrable Securities and was reviewed and expressly approved in writing by such
Holder expressly for use in the Registration Statement (it being understood that the Holder has
approved Annex A hereto for this purpose), such Prospectus or such form of Prospectus or in any
amendment or supplement thereto or (B) in the case of an occurrence of an event of the type
specified in Section 3(c)(ii)-(v), the use by such Holder of an outdated or defective Prospectus
after the Company has notified such Holder in writing that the Prospectus is outdated or defective
and prior to the receipt by such Holder of an Advice or an amended or supplemented Prospectus, but
only if and to the extent that following the receipt of the Advice or the amended or supplemented
Prospectus the misstatement or omission giving rise to such Loss would have been corrected;
provided, however, that the indemnity agreement contained in this Section 5(a) shall not apply to
amounts paid in settlement of any Losses if such settlement is effected without the prior written
consent of the Company, which consent shall not be unreasonably withheld. In no event shall the
liability of any selling Holder hereunder be greater in amount than the dollar amount of the net
proceeds received by such Holder upon the sale of the Registrable Securities giving rise to such
indemnification obligation.

(c) Conduct of Indemnification Proceedings. If any Proceeding shall be brought or
asserted against any Person entitled to indemnity hereunder (an “Indemnified Party”), such
Indemnified Party shall promptly notify the Person from whom indemnity is sought (the “Indemnifying
Party”) in writing, and the Indemnifying Party shall assume the defense thereof, including the
employment of counsel reasonably satisfactory to the Indemnified Party and the payment of all fees
and expenses incurred in connection with defense thereof; provided, that the failure of any
Indemnified Party to give such notice shall not relieve the Indemnifying Party of its obligations
or liabilities pursuant to this Agreement, except (and only) to the extent that it shall be finally
determined by a court of competent jurisdiction (which determination is not subject to appeal or
further review) that such failure shall have proximately and materially adversely prejudiced the
Indemnifying Party.

An Indemnified Party shall have the right to employ separate counsel in any such Proceeding
and to participate in the defense thereof, but the fees and expenses of such counsel shall be at
the expense of such Indemnified Party or Parties unless: (1) the Indemnifying Party has agreed in
writing to pay such fees and expenses; (2) the Indemnifying Party shall have failed promptly to
assume the defense of such Proceeding and to employ counsel reasonably satisfactory to such
Indemnified Party in any such Proceeding; or (3) the named parties to any such Proceeding
(including any impleaded parties) include both such Indemnified Party and the Indemnifying Party,
and such Indemnified Party shall have been advised by counsel that a conflict of interest is likely
to exist if the same counsel were to represent such Indemnified Party and the Indemnifying Party
(in which case, if such Indemnified Party notifies the Indemnifying Party in writing that it elects
to employ separate counsel at the expense of the Indemnifying Party, the Indemnifying Party shall
not have the right to assume the defense thereof and such counsel shall be at the expense of the
Indemnifying Party), provided, that the Indemnifying Party shall not be liable for the fees and
expenses of more than one separate firm of attorneys at any time for all Indemnified Parties. The
Indemnifying Party shall not be liable for any settlement of any such Proceeding effected without
its written consent, which consent shall not be unreasonably withheld. No Indemnifying Party
shall, without the prior written consent of the Indemnified Party, effect any settlement of any
pending Proceeding in respect of which any Indemnified Party is a party, unless such settlement
includes an unconditional release of such Indemnified Party from all liability on claims that are
the subject matter of such Proceeding.

All fees and expenses of the Indemnified Party (including reasonable fees and expenses to the
extent incurred in connection with investigating or preparing to defend such Proceeding in a manner
not inconsistent with this Section) shall be paid to the Indemnified Party, as incurred, within
twenty Trading Days of written notice thereof to the Indemnifying Party (regardless of whether it
is ultimately determined that an Indemnified Party is not entitled to indemnification hereunder;
provided, that the Indemnifying Party may require such Indemnified Party to undertake to reimburse
all such fees and expenses to the extent it is finally judicially determined that such Indemnified
Party is not entitled to indemnification hereunder).

(d) Contribution. If a claim for indemnification under Section 5(a) or 5(b) is
unavailable to an Indemnified Party (by reason of public policy or otherwise), then each
Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount
paid or payable by such Indemnified Party as a result of such Losses, in such proportion as is
appropriate to reflect the relative fault of the Indemnifying Party and Indemnified Party in
connection with the actions, statements or omissions that resulted in such Losses as well as any
other relevant equitable considerations. The relative fault of such Indemnifying Party and
Indemnified Party shall be determined by reference to, among other things, whether any action in
question, including any untrue or alleged untrue statement of a material fact or omission or
alleged omission of a material fact, has been taken or made by, or relates to information supplied
by, such Indemnifying Party or Indemnified Party, and the parties’ relative intent, knowledge,
access to information and opportunity to correct or prevent such action, statement or omission.
The amount paid or payable by a party as a result of any Losses shall be deemed to include, subject
to the limitations set forth in Section 5(c), any reasonable attorneys’ or other reasonable fees or
expenses incurred by such party in connection with any Proceeding to the extent such party would
have been indemnified for such fees or expenses if the indemnification provided for in this Section
was available to such party in accordance with its terms.

The parties hereto agree that it would not be just and equitable if contribution pursuant to
this Section 5(d) were determined by pro rata allocation or by any other method of allocation that
does not take into account the equitable considerations referred to in the immediately preceding
paragraph. Notwithstanding the provisions of this Section 5(d), no Holder shall be required to
contribute, in the aggregate, any amount in excess of the amount by which the proceeds actually
received by such Holder from the sale of the Registrable Securities subject to the Proceeding
exceeds the amount of any damages that such Holder has otherwise been required to pay by reason of
such untrue or alleged untrue statement or omission or alleged omission. 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 indemnity and contribution agreements contained in this Section are in addition to any
liability that the Indemnifying Parties may have to the Indemnified Parties and are not in
dimunition or limitation of the indemnification provisions under the Purchase Agreement.

6. Miscellaneous

(a) Remedies. In the event of a breach by the Company or by a Holder, of any of their
obligations under this Agreement, each Holder or the Company, as the case may be, in addition to
being entitled to exercise all rights granted by law and under this Agreement, including recovery
of damages, will be entitled to specific performance of its rights under this Agreement. The
Company and each Holder agree that monetary damages would not provide adequate compensation for any
losses incurred by reason of a breach by it of any of the provisions of this Agreement and hereby
further agrees that, in the event of any action for specific performance in respect of such breach,
it shall waive the defense that a remedy at law would be adequate.

(b) Compliance. Each Holder covenants and agrees that it will comply with the
prospectus delivery requirements of the Securities Act as applicable to it in connection with sales
of Registrable Securities pursuant to the Registration Statement.

(c) Discontinued Disposition. Each Holder further agrees by its acquisition of such
Registrable Securities that, upon receipt of a notice from the Company of the occurrence of any
event of the kind described in Section 3(c), such Holder will forthwith discontinue disposition of
such Registrable Securities under the Registration Statement until such Holder’s receipt of the
copies of a supplemented Prospectus or amended Registration Statement declared effective by the
Commission or until it is advised in writing (the “Advice”) by the Company that the use of the
applicable Prospectus may be resumed, and, in either case, has received copies of any additional or
supplemental filings that are incorporated or deemed to be incorporated by reference in such
Prospectus or Registration Statement. The Company may provide appropriate stop orders to enforce
the provisions of this paragraph.

(d) Piggy-Back Registrations. If at any time during the Effectiveness Period there
is not an effective Registration Statement covering all of the Registrable Securities and the
Company shall determine to prepare and file with the Commission a registration statement relating
to an offering for its own account or the account of others under the Securities Act of any of its
equity securities, other than on Form S-4 or Form S-8 (each as promulgated under the Securities
Act) or their then equivalents relating to equity securities to be issued solely in connection with
any acquisition of any entity or business or equity securities issuable in connection with stock
option or other employee benefit plans, then the Company shall send to each Holder written notice
of such determination and, if within fifteen days after receipt of such notice, any such Holder
shall so request in writing, the Company shall include in such registration statement all or any
part of such Registrable Securities such holder requests to be registered, subject to customary
underwriter cutbacks applicable to all holders of registration rights on a pro rata basis; provided
that if at any time after giving written notice of its intention to register any securities and
prior to the effective date of the registration statement filed in connection with such
registration, the Company shall determine for any reason not to register or to delay registration
of such securities, the Company may, at its election, give written notice of such determination to
such Holder and, thereupon, (i) in the case of a determination not to register, shall be relieved
of its obligation to register any Registrable Securities in connection with such registration (but
not from its obligation to pay expenses in accordance with Section 4 hereof), and (ii) in the case
of a determination to delay registering, shall be permitted to delay registering any Registrable
Securities being registered pursuant to this Section 6(d) for the same period as the delay in
registering such other securities.

(e) Amendments. This Agreement may be amended only by a writing signed by all of the
parties hereto. The Company may take any action herein prohibited, or omit to perform any act
herein required to be performed by it, only if the Company shall have obtained the written consent
to such amendment, action or omission to act, of each Purchaser.

(f) Notices. Any and all notices or other communications or deliveries required or
permitted to be provided hereunder shall be in writing and shall be deemed given and effective on
the earliest of (i) the date of transmission, if such notice or communication is delivered via
facsimile or email (provided the sender receives a machine-generated confirmation of successful
transmission) at the facsimile number specified in this Section prior to 5:00 p.m. (Pacific time)
on a Business Day, (ii) the next Business Day after the date of transmission, if such notice or
communication is delivered via facsimile at the facsimile numbdate and earlier than 11:59 p.m.
(Pacific time) on such date, (iii) the Business Day following the date of mailing, if sent by
nationally recognized overnight courier service, or (iv) upon actual receipt by the party to whom
such notice is required to be given.

	 	To the address of such Holder as it

appears in the stock transfer books of

the Company or such other address as may

the same manner, by such Person.

(g) Successors and Assigns. This Agreement shall inure to the benefit of and be
binding upon the successors and permitted assigns of each of the parties and shall inure to the
benefit of each Holder. The Company may not assign its rights or obligations hereunder without the
prior written consent of each Holder. The rights of the Holders hereunder, including the right to
have the Company register Registrable Securities pursuant to this Agreement, may be assigned by
each Holder to transferees or assignees of all or any portion of the Registrable Securities, but
only if (i) the Holder agrees in writing with the transferee or assignee to assign such rights, and
a copy of such agreement is furnished to the Company within a reasonable time after such
assignment, (ii) the Company is, within a reasonable time after such transfer or assignment,
furnished with written notice of the name and address of such transferee or assignee and the
securities with respect to which such registration rights are being transferred or assigned, (iii)
at or before the time the Company received the written notice contemplated by clause (ii) of this
sentence, the transferee or assignee agrees in writing with the Company to be bound by all of the
provisions contained herein and (iv) the transferee is an “accredited investor” as that term is
defined in Rule 501 of Regulation D.

(h) Execution and Counterparts. This Agreement may be executed in any number of
counterparts, each of which when so executed shall be deemed to be an original and, all of which
taken together shall constitute one and the same Agreement. In the event that any signature is
delivered by facsimile transmission, such signature shall create a valid binding obligation of the
party executing (or on whose behalf such signature is executed) the same with the same force and
effect as if such facsimile signature were the original thereof.

(i) Governing Law. All questions concerning the construction, validity, enforcement
and interpretation of this Agreement shall be governed by and construed and enforced in accordance
with the internal laws of the State of California, without regard to the principles of conflicts of
law thereof. Nothing contained herein shall be deemed to limit in any way any right to serve
process in any manner permitted by law. Each party hereto hereby irrevocably waives, to the
fullest extent permitted by applicable law, any and all right to trial by jury in any Proceeding
arising out of or relating to this Agreement or the transactions contemplated hereby. If any party
shall commence a Proceeding to enforce any provisions of this Agreement, then the prevailing party
in such Proceeding shall be reimbursed by the other parties for its attorney’s fees and other costs
and expenses incurred with the investigation, preparation and prosecution of such Proceeding.

(j) Cumulative Remedies. The remedies provided herein are cumulative and not
exclusive of any remedies provided by law.

(k) Severability. If any term, provision, covenant or restriction of this Agreement is
held by a court of competent jurisdiction to be invalid, illegal, void or unenforceable, the
remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in
full force and effect and shall in no way be affected, impaired or invalidated, and the parties
hereto shall use their reasonable efforts to find and employ an alternative means to achieve the
same or substantially the same result as that contemplated by such term, provision, covenant or
restriction. It is hereby stipulated and declared to be the intention of the parties that they
would have executed the remaining terms, provisions, covenants and restrictions without including
any of such that may be hereafter declared invalid, illegal, void or unenforceable.

(l) Headings. The headings in this Agreement are for convenience of reference only
and shall not limit or otherwise affect the meaning hereof.

(m) Independent Nature of Purchasers’ Obligations and Rights. The obligations of each
Purchaser under this Agreement are several and not joint with the obligations of any other
Purchaser hereunder, and no Purchaser shall be responsible in any way for the performance of the
obligations of any other Purchaser hereunder. The decision of each Purchaser to purchase
Securities pursuant to the Transaction Documents has been made independently of any other
Purchaser. Nothing contained herein or in any other agreement or document delivered at any
closing, and no action taken by any Purchaser pursuant hereto or thereto, shall be deemed to
constitute the Purchasers as a partnership, an association, a joint venture or any other kind of
entity, or create a presumption that the Purchasers are in any way acting in concert with respect
to such obligations or the transactions contemplated by this Agreement. Each Purchaser
acknowledges that no other Purchaser has acted as agent for such Purchaser in connection with
making its investment hereunder and that no Purchaser will be acting as agent of such Purchaser in
connection with monitoring its investment in the Securities or enforcing its rights under the
Transaction Documents. Each Purchaser shall be entitled to protect and enforce its rights,
including without limitation the rights arising out of this Agreement, and it shall not be
necessary for any other Purchaser to be joined as an additional party in any Proceeding for such
purpose. The Company acknowledges that each of the Purchasers has been provided with the same
Registration Rights Agreement for the purpose of closing a transaction with multiple Purchasers and
not because it was required or requested to do so by any Purchaser.

Annex A

Plan of Distribution

The Selling Stockholders and any of their pledgees, donees, transferees, assignees and
successors-in-interest may, from time to time, sell any or all of their shares of Common Stock on
any stock exchange, market or trading facility on which the shares are traded or in private
transactions. These sales may be at fixed or negotiated prices. The Selling Stockholders may use
any one or more of the following methods when selling shares:

	 	•	 	ordinary brokerage transactions and transactions in which the broker-dealer solicits
purchasers;

	 	•	 	block trades in which the broker-dealer will attempt to sell the shares as agent but
may position and resell a portion of the block as principal to facilitate the
transaction;

	 	•	 	purchases by a broker-dealer as principal and resale by the broker-dealer for its
account;

	 	•	 	an exchange distribution in accordance with the rules of the applicable exchange;

	 	•	 	privately negotiated transactions;

	 	•	 	short sales;

	 	•	 	broker-dealers may agree with the selling stockholders to sell a specified number of
such shares at a stipulated price per share;

	 	•	 	a combination of any such methods of sale; and

	 	•	 	any other method permitted pursuant to applicable law.

The Selling Stockholders may also sell shares under Rule 144 under the Securities Act, if
available, rather than under this prospectus.

Broker-dealers engaged by the Selling Stockholders may arrange for other brokers-dealers to
participate in sales. Broker-dealers may receive commissions or discounts from the Selling
Stockholders (or, if any broker-dealer acts as agent for the purchaser of shares, from the
purchaser) in amounts to be negotiated. The Selling Stockholders do not expect these commissions
and discounts to exceed what is customary in the types of transactions involved. Any profits on
the resale of shares of common stock by a broker-dealer acting as principal might be deemed to be
underwriting discounts or commissions under the Securities Act. Discounts, concessions,
commissions and similar selling expenses, if any, attributable to the sale of shares will be borne
by the selling stockholder. The selling stockholders may agree to indemnify any agent, dealer or
broker-dealer that participates in transactions involving sales of the shares if liabilities are
imposed on that person under the Securities Act. In connection with sales of the shares of Common
Stock or otherwise, the selling stockholders may enter into hedging transactions with
broker-dealers, which may in turn engage in short sales of the sales of Common Stock in the course
of hedging in positions they assume. The selling stockholders may also sell shares of Common Stock
short and deliver shares of Common Stock covered by this prospectus to close out short positions
and to return borrowed shares in connection with such short sales. The selling stockholders may
also loan or pledge shares of Common Stock to broker-dealers that in turn may sell such shares.

The Selling Stockholders may from time to time pledge or grant a security interest in some or
all of the Shares owned by them and, if they default in the performance of their secured
obligations, the pledgees or secured parties may offer and sell shares of Common Stock from time to
time under this prospectus, or under an amendment to this prospectus under Rule 424(b)(3) or other
applicable provision of the Securities Act of 1933 amending the list of selling stockholders to
include the pledgee, transferee or other successors in interest as selling stockholders under this
prospectus.

The selling stockholders have advised us that they have not entered into any agreements,
understandings or arrangements with any underwriters or broker-dealers regarding the sale of their
shares of common stock, nor is there an underwriter or coordinating broker acting in connection
with a proposed sale of shares of common stock by any selling stockholder. If we are notified in
writing by a Selling Stockholder that any material arrangement has been entered into with a
broker-dealer for the sale of Common Stock, we will file a supplement to this prospectus. If the
Selling Stockholders use this prospectus for any sale of the Common Stock, they will be subject to
the prospectus delivery requirements of the Securities Act.

The Selling Stockholders also may transfer the shares of Common Stock in other circumstances,
in which case the transferees, pledgees or other successors in interest will be the selling
beneficial owners for purposes of this prospectus and may sell the shares of Common Stock from time
to time under this prospectus after we have filed an amendment to this prospectus under Rule
424(b)(3) or otherwise comply with the Securities Act of 1933 to amend the list of selling
stockholders to include the pledgee, transferee or other successors in interest as selling
stockholders under this prospectus..

The Selling Stockholders and any broker-dealers or agents that are involved in selling the
shares may be deemed to be “underwriters” within the meaning of the Securities Act in connection
with such sales. In such event, any commissions received by such broker-dealers or agents and any
profit on the resale of the shares purchased by them may be deemed to be underwriting commissions
or discounts under the Securities Act. Each Selling Stockholder has represented and warranted to
the Company that it acquired the securities subject to this registration statement in the ordinary
course of such Selling Stockholder’s business and, at the time of its purchase of such securities
such Selling Stockholder had no agreements or understandings, directly or indirectly, with any
person to distribute any such securities.

The Company has advised each Selling Stockholder that it may not use shares registered on this
Registration Statement to cover short sales of Common Stock made prior to the date on which this
Registration Statement shall have been declared effective by the Commission.

We are required to pay all fees and expenses incident to the registration of the shares, but
we will not receive any proceeds from the sale of the Common Stock. We have agreed to indemnify
the selling stockholders against certain losses, claims, damages and liabilities, including
liabilities under the Securities Act.

The Selling Stockholders will be responsible to comply with the applicable provisions of the
Securities Act and Exchange Act, and the rules and regulations thereunder promulgated, including,
without limitation, Regulation M, as applicable to such Selling Stockholders in connection with
resales of their respective shares under this Registration Statement.
