authority to own and use its properties and assets and to carry on its business
as currently conducted. Neither the Company, nor any Subsidiary is in violation
or default of any of the provisions of its respective certificate or articles of
incorporation, bylaws or other organizational or charter documents. Each of the
Company and the Subsidiaries is duly qualified to conduct business and is in
good standing as a foreign corporation or other entity in each jurisdiction in
which the nature of the business conducted or property owned by it makes such
qualification necessary, except where the failure to be so qualified or in good

in: (i) a material adverse effect on the legality, validity or enforceability of
this Agreement or any documents executed in connection herewith (the
“Transaction Documents”), (ii) a material adverse effect on the results of
operations, assets, business, prospects or condition (financial or otherwise) of
the Company and the Subsidiaries, taken as a whole, or (iii) a material adverse
effect on the Company’s ability to perform in any material respect on a timely
basis its obligations under any Transaction Document (any of (i), (ii) or (iii),
a “Material Adverse Effect”) and no proceeding has been instituted in any such
jurisdiction revoking, limiting or curtailing or seeking to revoke, limit or
curtail such power and authority or qualification.

2.2 Authorization; Enforcement. The Company has the requisite corporate power
and authority to enter into and to consummate the transactions contemplated by
this Agreement and each of the other Transaction Documents and otherwise to
carry out its obligations hereunder and thereunder. The execution and delivery
of this Agreement and each of the other Transaction Documents by the Company and
the consummation by it of the transactions contemplated hereby and thereby have
been duly authorized by all necessary action on the part of the Company and no
further action is required by the Company, the Board of Directors or the
Company’s stockholders in connection herewith or therewith other than in
connection with the Required Approvals. This Agreement and each other
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 and thereof, will constitute the valid and binding obligation of
the Company enforceable against the Company in accordance with its terms,
except: (i) as limited by general equitable principles and applicable
bankruptcy, insolvency, reorganization, moratorium and other laws of general
application affecting enforcement of creditors’ rights generally, (ii) as

indirectly, made any offers or sales of any security or solicited any offers to

local and foreign tax returns which have been required to be filed and paid all
taxes shown thereon through the date hereof, to the extent that such taxes have

Except as disclosed in the SEC Reports, no tax deficiency has been determined
adversely to the Company or any Subsidiary which has had, or would reasonably be
expected to have, individually or in the aggregate, a Material Adverse Effect.
The Company has no knowledge of any federal, state or other governmental tax

confidential information, systems or procedures) (collectively, the
“Intellectual Property”), necessary for the conduct of their respective
businesses as conducted as of the date hereof, except to the extent that the
failure to own or possess adequate rights to use such Intellectual Property
would not, individually or in the aggregate, reasonably be expected to have a
Material Adverse Effect; the Company and the Subsidiaries have not received any
written notice of any claim of infringement or conflict which asserted
Intellectual Property rights of others, which infringement or conflict, if the
subject of an unfavorable decision, would reasonably be expected to result in a
Material Adverse Effect; there are no pending, or to the Company’s knowledge,

Subsidiary’s patents, patent applications or proprietary information, except for
such right or claim that would not, individually or in the aggregate, reasonably
be expected to result in a Material Adverse Effect; to the Company’s knowledge
no other entity or individual has any right or claim in any of the Company’s or
any of its Subsidiary’s patents, patent applications or any patent to be issued
therefrom by virtue of any contract, license or other agreement entered into
between such entity or individual and the Company or any Subsidiary or by any
non-contractual obligation, other than by written licenses granted by the
Company or any Subsidiary, except for such right or claim that would not,
individually or in the aggregate, reasonably be expected to result in a Material
Adverse Effect; the Company and the Subsidiaries have not received any written
notice of any claim challenging the rights of the Company or its Subsidiaries in

2.19 Disclosure Controls. The Company maintains systems of internal accounting
controls designed 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 GAAP and to maintain asset accountability;
(iii) access to assets is permitted only in accordance with management’s general
or specific authorization; and (iv) the recorded accountability for assets is
compared with the existing assets at reasonable intervals and appropriate action
is taken with respect to any differences. The Company is not aware of any
material weaknesses in its internal control over financial reporting. Since the
date of the latest audited financial statements of the Company included in the
Prospectus, there has been no change in the Company’s internal control over
financial reporting that has materially affected, or is reasonably likely to
materially affect, the Company’s internal control over financial reporting. The
Company has established disclosure controls and procedures (as defined in
Exchange Act Rules 13a-15 and 15d-15) for the Company and designed such
disclosure controls and procedures to ensure that material information relating
to the Company and the Subsidiaries is made known to the certifying officers by
others within those entities, particularly during the period in which the
Company’s Annual Report on Form 10-K or Quarterly Report on Form 10-Q, as the
case may be, is being prepared. The Company’s certifying officers have evaluated
the effectiveness of the Company’s controls and procedures as of a date within
90 days prior to the filing date of the Form 10-K for the fiscal year most
recently ended (such date, the “Evaluation Date”). The Company presented in its
Form 10-K for the fiscal year most recently ended the conclusions of the
certifying officers about the effectiveness of the disclosure controls and
procedures based on their evaluations as of the most recent Evaluation Date.
Since the most recent Evaluation Date, there have been no significant changes in
the Company’s internal controls (as such term is defined in Item 307(b) of
Regulation S-K under the Securities Act) or, to the Company’s knowledge, in
other factors that could significantly adversely affect the Company’s internal
controls. To the knowledge of the Company, the Company’s “internal controls over
financial reporting” and “disclosure controls and procedures” are effective.

the Company’s representations and warranties contained herein. The Purchaser
acknowledges that all of the documents filed by the Company with the SEC under
Sections 13(a), 14(a) or 15(d) of the Exchange Act that have been posted on the

Section 9. Resale Registration Rights.

9.1 The Purchaser may give a notice anytime on or after one hundred twenty
(120) days after the Closing Date (the “Registration Notice”) stating that the
Purchaser is exercising the right granted in Section 9.2 of this Agreement and
stating the number of Registrable Securities to be registered.

9.2 As soon as practicable, but in no event more than sixty (60) days (“Filing
Deadline”) after the date of the Registration Notice, the Company shall (a) file
with the SEC, or (b) have filed with the SEC a Resale Registration Statement
(the “Resale Registration Statement”) pursuant to Rule 415 under the Securities
Act pursuant to which all of the Shares and Warrant Shares (the “Registrable
Securities”) to be registered shall be included (on the initial filing or by
supplement thereto) to enable the public resale on a delayed or continuous basis
of such Registrable Securities by the Purchaser. The Company shall file the
Resale Registration Statement on such form as the Company may then utilize under
the rules of the SEC and use its commercially reasonable efforts to have the
Resale Registration Statement declared effective under the Securities Act as
soon as practicable. The Company agrees to use its commercially reasonable
efforts to maintain the effectiveness of the Resale Registration Statement,
including by filing any necessary post-effective amendments and prospectus
supplements, or, alternatively, by filing new registration statements relating
to the Registrable Securities as required by Rule 415 under the Securities Act,
continuously until the date (the “Resale Registration Expiration Date”) that is
the earlier of (i) one (1) year following the date of effectiveness of the
Resale Registration Statement or (ii) the date on which the Purchaser no longer
holds any Registrable Securities covered by such Resale Registration Statement.

9.3 Notwithstanding any other provisions of this Agreement to the contrary, the
Company shall cause (a) the Resale Registration Statement (as of the effective
date of Resale Registration Statement), any amendment thereof (as of the
effective date thereof) or supplement thereto (as of its date), (i) to comply in
all material respects with the applicable requirements of the Securities Act and
the rules and regulations of the SEC and (ii) not to contain any untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary in order to make the statements therein not
misleading, and (b) any related prospectus, preliminary prospectus and any
amendment thereof or supplement thereto, as of its date, (i) to comply in all
material respects with the applicable requirements of the Securities Act and the
rules and regulations of the SEC and (ii) not to contain any untrue statement of
a material fact or omit to state a material fact required to be stated therein
or necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading; provided, however, the
Company shall have no such obligations or liabilities with respect to any
written information pertaining to Purchaser and furnished to the Company by or
on behalf of Purchaser specifically for inclusion therein.

9.4 The Company shall notify the Purchaser: (a) when the Resale Registration
Statement or any amendment thereto has been filed with the SEC and when the
Resale Registration Statement or any post-effective amendment thereto has become
effective; (b) of any request by the SEC for amendments or supplements to the
Resale Registration Statement or the prospectus included therein or for
additional information; (c) of the issuance by the SEC of any stop order
suspending the effectiveness of the Resale Registration Statement or the
initiation of any proceedings for that purpose and of any other action, event or
failure to act that would cause the Resale Registration Statement not to remain
effective; and (d) of the receipt by the Company of any notification with
respect to the suspension of the qualification or exemption from qualification
of any Registrable Securities for sale in any jurisdiction or the initiation of
any proceeding for such purpose.

9.5 As promptly as practicable after becoming aware of such event, the Company
shall notify the Purchaser of the happening of any event (a “Suspension Event”),
of which the Company has knowledge, as a result of which the prospectus included
in any Resale Registration Statement, as then in effect, includes an untrue
statement of a material fact or omission to state a material fact required to be
stated therein or necessary to make the statements therein not misleading, and
use its best efforts promptly to prepare a supplement or amendment to any
Registration Statement to correct such untrue statement or omission, and deliver
such number of copies of such supplement or amendment to the Purchaser as such
Purchaser may reasonably request; provided, however, that, for not more than
fifteen (15) consecutive trading days (or a total of not more than thirty
(30) trading days in any twelve (12) month period), the Company may delay the
disclosure of material non-public information concerning the Company (as well as
prospectus or Resale Registration Statement updating) the disclosure of which at
the time is not, in the good faith opinion of the Company, in the best interests
of the Company; provided, further, that, if the Resale Registration Statement
was not filed on Form S-3, such number of days shall not include the fifteen
(15) calendar days following the filing of any Form 8-K, Form 10-Q or Form 10-K,
or other comparable form, for purposes of filing a post-effective amendment to
the Resale Registration Statement.

9.6 Upon a Suspension Event, the Company shall give written notice
(a “Suspension Notice”) to the Purchaser to suspend sales of the Registrable
Securities, and such notice shall state that such suspension shall continue only
for so long as the Suspension Event or its effect is continuing and the Company
is pursuing with reasonable diligence the completion of the matter giving rise
to the Suspension Event or otherwise taking all reasonable steps to terminate
suspension of the effectiveness or use

- 9 -

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

 

of the Registration Statement. In no event shall the Company, without the prior
written consent of the Purchaser, disclose to the Purchaser any of the facts or
circumstances giving rise to the Suspension Event. The Purchaser shall not
effect any sales of the Registrable Securities pursuant to such Registration
Statement (or such filings) at any time after it has received a Suspension
Notice and prior to receipt of an End of Suspension Notice. The Purchaser may
resume effecting sales of the Registrable Securities under the Registration
Statement (or such filings) following further notice to such effect (an “End of
Suspension Notice”) from the Company. This End of Suspension Notice shall be
given by the Company to the Purchaser in the manner described above promptly
following the conclusion of any Suspension Event and its effect.

9.7 Notwithstanding any provision herein to the contrary, if the Company gives a
Suspension Notice pursuant to this Section 9 with respect to the Resale
Registration Statement, the Company shall extend the period during which such
Resale Registration Statement shall be maintained effective under this Agreement
by the number of days during the period from the date of the giving of the
Suspension Notice to and including the date when Purchaser shall have received
the End of Suspension Notice and copies of the supplemented or amended
Prospectus necessary to resume sales; provided, however, such period of time
shall not be extended beyond the date that the Registrable Securities can be
sold under Rule 144 without restriction. The Company shall bear all Registration
Expenses incurred in connection with the registration of the Registrable
Securities pursuant to this Agreement. “Registration Expenses” shall mean any
and all expenses incident to the performance of or compliance with this
Agreement, including without limitation: (a) all registration and filing fees;
(b) all fees and expenses associated with a required listing of the Registrable
Securities on any securities exchange; (c) fees and expenses with respect to
filings required to be made with an exchange or any securities industry
self-regulatory body; (d) fees and expenses of compliance with securities or
“blue sky” laws (including reasonable fees and disbursements of counsel for the
underwriters or holders of securities in connection with blue sky qualifications
of the securities and determination of their eligibility for investment under
the laws of such jurisdictions); (e) printing, messenger, telephone and delivery
expenses of the Company; (f) fees and disbursements of counsel for the Company
and customary fees and expenses for independent certified public accountants
retained by the Company (including the expenses of any comfort letters, or costs
associated with the delivery by independent certified public accountants of a
comfort letter or comfort letters, if such comfort letter or comfort letters is
required by the managing underwriter); (g) securities acts liability insurance,
if the Company so desires; (h) all internal expenses of the Company (including,
without limitation, all salaries and expenses of its officers and employees
performing legal or accounting duties); (i) the expense of any annual audit;
(j) the fees and expenses of any Person, including special experts, retained by
the Company; (k) any underwriting fees, discounts or commissions attributable to
the sale of such Registrable Securities, and (l) any legal fees and expenses of
counsel to the Purchaser.

9.8 Indemnification.

(a) In the event of the offer and sale of the Registrable Securities held by the
Purchaser under the Securities Act, the Company agrees to indemnify and hold
harmless Purchaser and its directors, officers, employees, Affiliates and agents
and each person who controls Purchaser within the meaning of the Securities Act
or the Exchange Act (collectively, the “Purchaser Indemnified Parties”) from and
against any losses, claims, damages or liabilities, joint or several, or any
actions in respect thereof to which each Purchaser Indemnified Party may become
subject under the Securities Act or the Exchange Act, insofar as such losses,
claims, damages, liabilities or actions arise out of or are based upon (i) any
untrue statement or alleged untrue statement of a material fact contained in the
Resale Registration Statement or in any amendment thereof, in each case at the
time such became effective under the Securities Act, or in any the preliminary
prospectus or other information that is deemed, under Rule 159 promulgated under
the Securities Act to have been conveyed to purchasers of securities at the time
of sale of such securities (“Disclosure Package”), prospectus or in any
amendment thereof or supplement thereto, or (ii) the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein (in the case of a Disclosure Package or
any prospectus, in the light of the circumstances under which they were made)
not misleading, and shall reimburse, as incurred, the Purchaser Indemnified
Parties for any legal or other expenses reasonably incurred by them in
connection with investigating or defending any such loss, claim, damage,
liability or action in respect thereof; provided, however, that the Company
shall not be liable in any such case to the extent that such loss, claim, damage
or liability arises out of or is based upon any untrue statement or omission
made in the Resale Registration Statement, the Disclosure Package, any
prospectus or in any amendment thereof or supplement thereto in reliance upon
and in conformity with written information pertaining to Purchaser and furnished
to the Company by or on behalf of such Purchaser Indemnified Party specifically
for inclusion therein; provided further, however, that the Company shall not be
liable in any such case to the extent that such loss, claim, damage or liability
arises out of or is based upon any untrue statement or alleged untrue statement
or omission or alleged omission made in the Disclosure Package, where (i) such
statement or omission had been eliminated or remedied in any subsequently filed
amended prospectus or prospectus supplement (the Disclosure Package, together
with such updated documents, the “Updated Disclosure Package”), the filing of
which the Purchaser had been notified in accordance with the terms of this
Agreement, (ii) such Updated Disclosure Package was available at the time the
Purchaser sold Registrable Securities under the Resale Registration Statement,
(iii) such Updated Disclosure Package was not furnished by the Purchaser to the
person or entity asserting the loss, liability, claim, damage or liability at or
prior to the time such furnishing is required by the

- 10 -

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

 

Securities Act and (iv) the Updated Disclosure Package would have cured the
defect giving rise to such loss, liability, claim, damage or action; and
provided further, however, that this indemnity agreement will be in addition to
any liability that the Company may otherwise have to such Resale Indemnified
Party. Such indemnity shall remain in full force and effect regardless of any
investigation made by or on behalf of any Purchaser Indemnified Parties and
shall survive the transfer of the Shares by any Purchaser.

(b) As a condition to including any Registrable Securities to be offered by the
Purchaser in any registration statement filed pursuant to this Agreement,
Purchaser agrees to indemnify and hold harmless the Company, each of its
directors, each of its officers who signs the Resale Registration Statement, as
well as any officers, employees, Affiliates and agents of the Company, and each
person, if any, who controls the Company within the meaning of the Securities
Act or the Exchange Act (a “Company Indemnified Party”) from and against any
losses, claims, damages or liabilities or any actions in respect thereof, to
which a Company Indemnified Party may become subject under the Securities Act or
the Exchange Act, insofar as such losses, claims, damages, liabilities or
actions arise out of or are based upon (i) any untrue statement or alleged
untrue statement of a material fact contained in the Resale Registration
Statement or in any amendment thereof, in each case at the time such became
effective under the Securities Act, or in any Disclosure Package, prospectus or
in any amendment thereof or supplement thereto, or (ii) the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein (in the case of the Disclosure Package
or any prospectus, in the light of the circumstances under which they were made)
not misleading, but in each case only to the extent that the untrue statement or
omission or alleged untrue statement or omission was made in reliance upon and
in conformity with written information pertaining to Purchaser and furnished to
the Company by or on behalf of Purchaser specifically for inclusion therein;
and, subject to the limitation set forth immediately preceding this clause,
shall reimburse, as incurred, the Company Indemnified Parties for any legal or
other expenses reasonably incurred by them in connection with investigating or
defending any loss, claim, damage, liability or action in respect thereof. Such
indemnity shall remain in full force and effect regardless of any investigation
made by or on behalf of the Purchaser, or any such director, officer, employees,
Affiliates and agents and shall survive the transfer of such Registrable
Securities by the Purchaser, and such Purchaser shall reimburse the Company, and
each such director, officer, employees, Affiliates and agents for any legal or
other expenses reasonably incurred by them in connection with investigating,
defending, or settling and such loss, claim, damage, liability, action, or
proceeding; provided, however, that such indemnity agreement found in this
Section 9.8(b) shall in no event exceed the gross proceeds from the offering
received by such Purchaser. Such indemnity shall remain in full force and
effect, regardless of any investigation made by or on behalf of the Company or
any such director, officer, employees, Affiliates and agents and shall survive
the transfer by the Purchaser of such Registrable Securities.

(c) Promptly after receipt by a Purchaser Indemnified Party or a Company
Indemnified Party (each, an “Indemnified Party”) of notice of the commencement
of any action or proceeding (including a governmental investigation), such
Indemnified Party will, if a claim in respect thereof is to be made against the
indemnifying party under this Section, notify the indemnifying party of the
commencement thereof; but the omission to so notify the indemnifying party will
not relieve the indemnifying party from liability under paragraph (a) or
(b) above unless and to the extent it did not otherwise learn of such action and
the indemnifying party has been materially prejudiced by such failure. In case
any such action is brought against any Indemnified Party, and it notifies the
indemnifying party of the commencement thereof, the indemnifying party will be
entitled to participate therein and, to the extent that it may wish, jointly
with any other indemnifying party similarly notified, to assume the defense
thereof, with counsel reasonably satisfactory to such Indemnified Party (who
shall not, except with the consent of the Indemnified Party, be counsel to the
indemnifying party), and after notice from the indemnifying party to such
Indemnified Party of its election so to assume the defense thereof the
indemnifying party will not be liable to such Indemnified Party under this
Section for any legal or other expenses, other than reasonable costs of
investigation, subsequently incurred by such Indemnified Party in connection
with the defense thereof; provided, however, if such Indemnified Party shall
have been advised by counsel that there are one or more defenses available to it
that are in conflict with those available to the indemnifying party (in which
case the indemnifying party shall not have the right to direct the defense of
such action on behalf of the Indemnified Party), the reasonable fees and
expenses of such Indemnified Party’s counsel shall be borne by the indemnifying
party. In no event shall the indemnifying party be liable for the fees and
expenses of more than one counsel (together with appropriate local counsel) at
any time for any Indemnified Party in connection with any one action or separate
but substantially similar or related actions arising in the same jurisdiction
out of the same general allegations or circumstances. No indemnifying party
shall, without the prior written consent of the Indemnified Party (not to be
unreasonably withheld or delayed), effect any settlement of any pending or
threatened action in respect of which any Indemnified Party is or could have
been a party and indemnity could have been sought hereunder by such Indemnified
Party unless such settlement (i) includes an unconditional release of such
Indemnified Party from all liability on any claims that are the subject matter
of such action and (ii) does not include a statement as to or an admission of
fault, culpability or a failure to act by or on behalf of any Indemnified Party.
If the indemnification provided for in this Section is unavailable or
insufficient to hold harmless an Indemnified Party under subsections (a) or
(b) above, then each indemnifying party shall contribute to the amount paid or
payable by such Indemnified Party as a result of the losses, claims, damages or
liabilities (or actions in respect thereof) referred to in subsection (a) or
(b) above in such proportion as is appropriate to reflect the relative fault of
the indemnifying party or parties on the one hand and the Indemnified

- 11 -

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

 

Party on the other in connection with the statements or omissions that resulted
in such losses, claims, damages or liabilities (or actions in respect thereof)
as well as any other relevant equitable considerations. The relative fault of
the parties shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by the Company
on the one hand or the Purchaser or Purchaser Indemnified Party, as the case may
be, on the other, and the parties’ relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The amount paid by an Indemnified Party as a result of the losses, claims,
damages or liabilities referred to in the first sentence of this subsection
(c) shall be deemed to include any legal or other expenses reasonably incurred
by such Indemnified Party in connection with investigating or defending any
action or claim that is the subject of this subsection (c). The parties agree
that it would not be just and equitable if contributions were determined by pro
rata allocation (even if the Purchaser was treated as one entity for such
purpose) or any other method of allocation that does not take account of the
equitable considerations referred to above. Notwithstanding any other provision
of this subsection (c), Purchaser shall not be required to contribute any amount
in excess of the amount by which the net proceeds received by the Purchaser from
the sale of the Registrable Securities pursuant to the Resale Registration
Statement exceeds the amount of damages that Purchaser 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.

(d) The agreements contained in this Section shall survive the sale of the
Registrable Securities pursuant to the Resale Registration Statement and shall
remain in full force and effect, regardless of any termination or cancellation
of this Agreement or any investigation made by or on behalf of any Indemnified
Party.

Section 10. Furnishing of Information. As long as 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
Purchaser owns Securities, if the Company is not required to file reports
pursuant to such laws, the Company will (i) prepare and furnish to Purchaser and
make publicly available in accordance with Rule 144(c) such information as is
required for Purchaser to sell the Securities under Rule 144, and (ii) provide
audited annual financial statements to Purchaser. The Company Inc. further
covenants that it will take such further action as Purchaser may reasonably
request, all to the extent required from time to time to enable Purchaser to
sell the Securities without registration under the Securities Act within the
limitation of the exemptions provided by Rule 144.

Section 11. Indemnification. In addition to any other indemnity provided in the
Transaction Documents, the Company will indemnify and hold Purchaser and its
directors, officers, shareholders, partners, employees, advisers, affiliates 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 (i) any
misrepresentation, breach or inaccuracy of any representation, warranty,
covenant or agreement made by the Company in any Transaction Document and
(ii) any action instituted against a Purchaser Party in any capacity, or any of
them or their respective affiliates, by any stockholder of the Company who is
not an affiliate of such Purchaser Party, with respect to any of the
transactions contemplated by this Agreement. 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.

Section 12. Governing Law; Jurisdiction; Waiver of Jury Trial. This Agreement
shall be construed under the laws of the state of California, without regard to
principles of conflicts of law or choice of law that would permit or require the
application of the laws of another jurisdiction. The Company and the Purchaser
each hereby agrees that all actions or proceedings arising directly or
indirectly from or in connection with this Agreement shall be litigated only in
the Superior Court of the State of California or the United States District
Court for the Central District of California located in Los Angeles County,
California. The Company and the Purchaser each consents to the exclusive
jurisdiction and venue of the foregoing courts and consents that any process or
notice of motion or other application to either of said courts or a judge
thereof may be served inside or outside the State of California or the Central
District of California by generally recognized overnight courier or certified or
registered mail, return receipt requested, directed to such party at its or his
address set forth below (and service so made shall be deemed “personal service”)
or by personal service or in such other manner as may be permissible under the
rules of said courts. THE COMPANY AND THE PURCHASER EACH HEREBY WAIVES ANY RIGHT
TO A JURY TRIAL IN CONNECTION WITH ANY LITIGATION PURSUANT TO THIS AGREEMENT.

Section 13. Counterparts. This Agreement may be executed in two or more
identical counterparts, all of which 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; provided that a facsimile signature
shall be considered due execution and shall be binding upon the signatory
thereto with the same force and effect as if the signature were an original, not
a facsimile signature.

Section 14. Headings. The headings of this Agreement are for convenience of
reference and shall not form part of, or affect the interpretation of, this
Agreement.

Section 15. Severability. If any provision of this Agreement shall be invalid or
unenforceable in any jurisdiction, such invalidity or unenforceability shall not
affect the validity or enforceability of the remainder of this Agreement in that
