articles of incorporation or bylaws. Company is duly qualified to conduct business and is in good
standing as a foreign corporation in each jurisdiction in which the nature of the business

effect on the legality, validity or enforceability of any Transaction Document, (ii) a material and
adverse effect on the results of operations, assets, prospects, business or financial condition of
the Company, or (iii) a material and adverse impairment to the Company’s ability to perform on a
timely basis its obligations under any Transaction Document (a “Material Adverse Effect”).

(b)  Authorization; Enforcement. The Company has the requisite corporate power and
authority to enter into and to consummate the transactions contemplated by each of the Transaction

to, the sale and delivery of the Shares) 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 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

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

debt or otherwise) or other understanding to which the Company is a party or by which any property
or asset of the Company is bound, except to the extent that such conflict, default, termination,
amendment, acceleration or cancellation right could not reasonably be expected to have a Material
Adverse Effect, or (iii) result in a violation of any law, rule, regulation, order, judgment,
injunction, decree or other restriction of any court or governmental authority to which the Company
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

by which any property or asset of the Company is bound, except to the extent that such violation
could not reasonably be expected to have a Material Adverse Effect.

(d)  Filings, Consents and Approvals. The Company is not required to obtain any

provided for in the Transaction Documents or imposed by applicable securities laws and shall not be
subject to preemptive or similar rights of stockholders. Assuming the accuracy of the
representations and warranties of the Purchasers, the Shares will be issued in compliance with all
applicable federal and state securities laws. The issue and sale of the Shares will not,
immediately or with the passage of time, obligate the Company to issue shares of its common stock

holder of Company securities to adjust the exercise, conversion, exchange or reset price under such
securities.

reorganizations, recapitalizations, reclassifications or other similar events, there are no
anti-dilution or price adjustment provisions contained in any security issued by the Company (or in

not obligate the Company to issue shares of common stock or other securities to any person (other
than the Purchasers) and will not result in a right of any holder of securities to adjust the

obligations hereunder and thereunder. The execution, delivery and performance by such Purchaser of

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 Shares are “restricted
securities” and have not been registered under the Securities Act or any applicable state
securities law and is acquiring the Shares as principal for its own account for investment purposes

of such 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 Shares for any period of time. Such
Purchaser is acquiring the Shares 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 Shares.

bear the economic risk of an investment in the Shares and, at the present time, is able to afford a
complete loss of such investment.

Shares; (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 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 Shares,
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 Effectiveness Date. Each Purchaser agrees that it will not
use any of the 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)  Independent Investment Decision. Such Purchaser has independently evaluated the
merits of its decision to purchase Shares 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 Shares 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 Shares.

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 Shares and Common Stock underlying the Shares 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
Shares 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 Shares 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 Shares by a Purchaser to an Affiliate of such Purchaser, provided that the
transferee agrees to the terms and conditions of the Shares, 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
Shares.

(b)  Legends. Certificates evidencing the Shares and any shares of Common Stock
underlying the Shares will contain the following legend, until such time as they are not required
under Section 4.1(c):

THESE SECURITIES HAVE NOT 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 Shares, 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 Shares 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, without the legend set forth above (i) while a registration statement (including the
Registration Statement) covering the resale of such Shares is effective under the Securities Act,
(ii) following any sale of such Shares pursuant to Rule 144 (assuming the transferor is not an
affiliate of the Company), (iii) if such Shares 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 Shares, 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 Shares and a reasonably
acceptable opinion of counsel to the extent required by Section 4.1(a), reissue a certificate
representing such Shares 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 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 Shares the Company shall fail to issue and deliver to such
Purchaser a certificate representing such Shares 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 Furnishing of Information. As long as any Purchaser owns the Shares, 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 Shares, 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
under Rule 144. The Company further covenants that it will take such further action as any holder
of Shares may reasonably request, all to the extent required from time to time to enable such
Person to sell the Shares without registration under the Securities Act within the limitation of
the exemptions provided by Rule 144.

4.3 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 Shares in a manner that would require the registration
under the Securities Act of the sale of the Shares to the Purchasers, or that will be integrated
with the offer or sale of the Shares for purposes of the rules and regulations of any Trading
Market.

4.4 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 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.

4.7 Use of Proceeds. The Company intends to use the net proceeds from the sale of the
Shares hereunder for working capital and general corporate purposes and not to redeem any Common
Stock.

Transfer Agent fees, stamp taxes and other taxes and duties levied in connection with the sale and

6.3 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.

6.4 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.

6.5 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 Shares in compliance with
this Agreement and applicable law, provided such transferee shall agree in writing to be bound,
with respect to the transferred Shares, by the terms and conditions of this Agreement that apply to
the “Purchasers.”

6.6 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 .

6.7 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 Delaware, 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.

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

6.9 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.

6.10 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.

6.11 Replacement of Certificates. If any certificate or instrument evidencing any
Shares 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 certificates. If a replacement certificate or
instrument evidencing any Shares 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.

6.12 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.

6.13 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.

6.14 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 Shares 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 Shares 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.

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

6.16 Entire Agreement. The Transaction Documents, together with the Exhibits and
Schedules thereto which are incorporated herein by reference, contain the entire understanding of
the parties with respect to the subject matter hereof and supersede all prior agreements,
understandings, discussions and representations, oral or written, with respect to such matters,
which the parties acknowledge have been merged into such documents, exhibits and schedules. At or
after the Closing, and without further consideration, the Company and the Purchasers will execute
and deliver to the other such further documents as may be reasonably requested in order to give
practical effect to the intention of the parties under the Transaction Documents.

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 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 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 1 hereto and hereby
undertakes to do so.

In the event that the undersigned transfers all or any portion of the Company’s Common Stock 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.

We are counsel to Clearant, Inc., a Delaware corporation (the “Company”), and have represented
the Company in connection with that certain Stock Purchase Agreement, dated as of April      , 2007,
entered into by and among the Company and the buyers named therein (collectively, the “Purchasers”)

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

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 Shares 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 March 29, 2007. This letter shall serve as our standing
instructions with regard to this matter.

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 Certificate 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 7), 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 8, 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.

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
pursuant to the Agreement. Based upon and subject to the following assumptions, we are of the
opinion that the sale of the Shares 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 Shares for its own account, for
investment purposes and without a view to distribution. The Shares 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.

under the Securities Act within five (5) Business Days after the date that the Company is notified
(orally or in writing, whichever is earlier) by the Commission that a Registration Statement will

Statement may be accelerated) and shall use its reasonable best efforts to keep the Registration
Statement continuously effective under the Securities Act until the earlier of the date that all
Shares covered by the Registration Statement have been sold or may be sold by non-affiliates
without volume restrictions pursuant to Rule 144(k) as determined by the counsel to the Company
pursuant to a written opinion letter to such effect, addressed and acceptable to the Company’s
transfer agent and the affected Holders (the “Effectiveness Period”). In the event of a stock
split, stock dividend or similar transaction with respect to the Shares, such Registration
Statement shall also cover, to the extent allowable under the Securities Act and the rules
promulgated thereunder (including Rule 416), such indeterminate number of additional shares of
Common Stock resulting therefrom. It is agreed and understood that the Company shall, from time to
time, be obligated to file an additional Registration Statement to cover any Shares which are not
registered for resale pursuant to a pre-existing Registration Statement.

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 Shares
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 Shares; (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 Business 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
Shares 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 Business Days prior to such filing) and (if requested by any such Person) confirm
such notice in writing no later than one Business 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 Shares 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
Shares 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 Shares 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 Shares 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 Shares, 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 Shares 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 Shares 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 Shares 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 Shares 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 Shares without legend upon sale by the holder of such
shares of Shares under the Registration Statement.

(h) Following the occurrence of any event contemplated by Section 3(b)(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 the Trading Market, prepare and file with the
Trading Market an additional shares listing application covering all of the Shares, (ii) take all
steps necessary to cause such Shares to be approved for listing on the 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 Shares
on a 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 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.

(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 Shares 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, and (B) in compliance with applicable state
securities or Blue Sky laws), (ii) printing expenses (including, without limitation, expenses of
printing certificates for Shares and of printing prospectuses if the printing of prospectuses is
reasonably requested by the holders of a majority of the Shares 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 Shares 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 Shares 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(b)(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(c) 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(a) 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 Shares 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 Shares 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(b)(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 (as defined in Section 6(c) 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 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 Shares 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 Business 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 Shares 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 Shares pursuant to the Registration Statement.

(c) Discontinued Disposition. Each Holder further agrees by its acquisition of such
Shares that, upon receipt of a notice from the Company of the occurrence of any event of the kind
described in Section 3(b), such Holder will forthwith discontinue disposition of such Shares 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 Shares 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 Shares 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 Shares 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 Shares 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

(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 Shares pursuant to this Agreement, may be assigned by each Holder to
transferees or assignees of all or any portion of the Shares, 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,

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

(h) Execution and Counterparts. This Agreement may be executed in any number of

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.

IN WITNESS WHEREOF, the parties have executed this Registration Rights Agreement as of the
date first written above.

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.
