recapitalization, merger, or similar event, shall not be sold, assigned, transferred or pledged
except upon the conditions specified in this Agreement, which conditions are intended to ensure
compliance with the provisions of the Securities Act. Each Holder or transferee shall cause any

the following form (in addition to any legends required by agreement or by applicable state
securities laws):




THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”). SUCH SECURITIES MAY NOT
BE TRANSFERRED UNLESS A REGISTRATION STATEMENT UNDER THE ACT IS IN
EFFECT AS TO SUCH TRANSFER OR IN THE OPINION OF COUNSEL FOR THE COMPANY,
SUCH TRANSFER MAY BE MADE PURSUANT TO RULE 144 OR RULE 701 OR
REGISTRATION UNDER THE ACT IS OTHERWISE UNNECESSARY IN ORDER FOR SUCH
TRANSFER TO COMPLY WITH THE ACT.




THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO RESTRICTIONS
UPON TRANSFER AS SET FORTH IN AN AGREEMENT BETWEEN THE ISSUER AND THE
ORIGINAL HOLDER OF THESE SHARES, A COPY OF WHICH MAY BE OBTAINED AT THE
PRINCIPAL OFFICE OF THE ISSUER. SUCH RESTRICTIONS UPON TRANSFER ARE
BINDING ON TRANSFEREES OF THESE SHARES.



          Each Holder consents to the Company making a notation on its records and giving stop transfer
instructions to any transfer agent of its capital stock in order to implement the restrictions on
transfer established in this Agreement.




-3-









 








          The Company shall be obligated to reissue promptly certificates removing the first of the
above legends at the request of any Holder if the Holder shall have obtained an opinion of counsel
reasonably acceptable to the Company to the effect that the securities proposed to be disposed of
may lawfully be so disposed of without registration, qualification or legend and will remove the
second legend upon termination of this Agreement.




     4. Notice of Proposed Transfers. The holder of each certificate representing
Restricted Securities by acceptance thereof agrees to comply in all respects with the provisions of
this Section 4. Without in any way limiting the immediately preceding sentence, no sale,
assignment, transfer or pledge of Restricted Securities shall be made by any holder thereof to any
person unless such person shall first agree (in the case of a pledge, prior to any transfer
pursuant to an exercise of rights under the pledge) in writing to be bound by the restrictions of
this Agreement including, without limitation, Section 7. Prior to any proposed sale, assignment,
transfer or transfer pursuant to the exercise of rights under a pledge (a “pledge transfer”) of any
Restricted Securities, unless there is in effect a registration statement under the Securities Act
covering the proposed transfer, the holder thereof shall give written notice to the Company of such
holder’s intention to effect such transfer, sale, assignment or pledge transfer. Each such notice
shall describe the manner and circumstances of the proposed transfer, sale, assignment or pledge
transfer in sufficient detail. Each certificate evidencing the Restricted Securities transferred
as above provided shall bear, except if such transfer is made pursuant to Rule 144, the appropriate
restrictive legend set forth in Section 3 above, except that such certificate shall not bear such
restrictive legend if in the opinion of counsel for such holder and counsel for the Company such
legend is not required in order to establish compliance with any provision of the Securities Act.
Notwithstanding the foregoing, each holder of Restricted Securities agrees that it will not request
that a transfer of the Restricted Securities be made or that the legend set forth in Section 3 be
removed from the certificate representing the Restricted Securities, solely in reliance on Rule
144(k), if as a result thereof the Company would be rendered subject to the reporting requirements
of the Exchange Act.



     5. Registration.



          5.1 Requested Registration.




               (a) Request for Registration. In case the Company shall receive from Initiating
Holders a written request that the Company effect any registration with respect to shares of
Registrable Securities, the Company will:



                    (i) promptly give written notice of the proposed registration to all other Holders; and



                    (ii) as soon as practicable, use its best efforts to effect such registration (including,
without limitation, appropriate qualification under applicable state securities laws and
appropriate compliance with applicable regulations issued under the Securities Act and any other
governmental requirements or regulations) as may be so requested and as would permit or facilitate
the sale and distribution of such Registrable Securities, including all or such portion of the
Registrable Securities of any Holder or Holders joining in such request by delivering a written
notice to such effect to the Company within 20 days after



-4-









 







the date of such written notice from the Company subject to the limitations set forth in
Section 5.1(b).



     Notwithstanding the foregoing, the Company shall not be obligated to take any action to effect
or complete any such registration pursuant to this Section 5.1:



                         (A) Prior to the earlier of (i) six months after the effective date of the Company’s first
registered public offering of its Common Stock or (ii) May 19, 2010;



                         (B) Unless the requested registration would have an aggregate offering price of all
Registrable Securities sought to be registered by all Holders of not less than $15,000,000;



                         (C) During the period starting with the date 60 days prior to the Company’s estimated date of
filing of, and ending on the date 180 days immediately following the effective date of, any
registration statement pertaining to securities of the Company (other than a registration of
securities in a Rule 145 transaction or with respect to an employee benefit plan), provided that
the Company is actively employing in good faith commercially reasonable efforts to cause such
registration statement to become effective;



                         (D) After the Company has effected two registrations pursuant to this Section 5.1(a) and such
registration has been declared or ordered effective;



                         (E) If the Company, within 30 days of the receipt of the written request of the Initiating
Holders, gives notice of its bona fide intention to effect the filing of a registration statement
with the Commission within 120 days of receipt of such request (other than with respect to a
registration statement relating to a Rule 145 transaction, an offering solely to employees or any
other registration which is not appropriate for the registration of Registrable Securities),
provided that the Company makes reasonable good faith efforts to complete such offering;



                         (F) If the Company shall furnish to the Initiating Holders a certificate signed by the
President of the Company stating that in the good faith judgment of the Board of Directors it would
be detrimental to the Company or its stockholders for a registration statement to be filed in the
near future. In such case, the Company’s obligation under this Section 5.1(a) shall be deferred
for a period not to exceed 120 days from the date of receipt of the written request from the
Initiating Holders, provided that the Company may not exercise this deferral right more than once
per 12 month period.



     Subject to the foregoing clauses (A) through (F), the Company shall file a registration
statement covering the Registrable Securities so requested to be registered as soon as practicable
after receipt of the request or requests of the Initiating Holders.



               (b) Underwriting. If the Initiating Holders intend to distribute Registrable
Securities by means of an underwriting, they shall so advise the Company as part of their request
made pursuant to Section 5.1(a), and the Company shall advise the Holders as part of the notice
given pursuant to Section 5.1(a)(i) that the right of any Holder to registration



-5-









 







pursuant to Section 5.1 shall be conditioned upon such Holder’s participation in such
underwriting arrangements, and the inclusion of such Holder’s Registrable Securities in the
underwriting to the extent requested shall be limited to the extent provided herein.



     The Company shall, together with all Holders proposing to distribute their securities through
such underwriting, enter into an underwriting agreement in customary form with the managing
underwriter selected for such underwriting by a majority in interest of the shares to be registered
held by the Initiating Holders, but subject to the Company’s reasonable approval. Notwithstanding
any other provision of this Section 5.1, if the managing underwriter advises the Initiating Holders
in writing that marketing factors require a limitation of the number of shares to be underwritten,
then the Company shall so advise all Holders requesting to be included in the registration and
underwriting and the number of shares that may be included in the registration and underwriting
shall be allocated among all Holders requesting to be included in the registration and underwriting
in proportion, as nearly as practicable, to the respective amounts of Registrable Securities held
by them. No Registrable Securities excluded from the underwriting by reason of the underwriter’s
marketing limitation shall be included in such registration. To facilitate the allocation of
shares in accordance with the above provisions, the Company or the underwriters may round the
number of shares allocated to any Holder to the nearest 100 shares. If any Holder of Registrable
Securities disapproves of the terms of the underwriting, such person may elect to withdraw
therefrom by written notice to the Company.



               (c) Notwithstanding anything to the contrary contained in this Section 5.1, Holders shall not
be deemed to have used or forfeited their rights to registration of their Registrable Securities
under this Section 5.1, if a registration of Registrable Securities is conducted pursuant to an
underwritten offering undertaken after the exercise of the Holders’ rights under this Section 5.1
and the underwriters advise the Company and/or the Holders that marketing factors require the
Company to limit the number of Registrable Securities to be sold in such offering to a number less
than seventy-five percent (75%) of the Registrable Securities requested to be registered by the
persons exercising such demand right.



          5.2 Company Registration.




               (a) Notice of Registration. If at any time or from time to time the Company shall
determine to register any of its equity securities, either for its own account or the account of a
Holder or other holders, other than (i) a registration relating solely to employee benefit plans,
(ii) a registration relating solely to a Rule 145 transaction, or (iii) a registration in which the
only equity security being registered is Common Stock issuable upon conversion of convertible debt
securities which are also being registered, the Company will:



                    (i) promptly give to each Holder written notice thereof; and



                    (ii) include in such registration (and any related qualifications including compliance with
Blue Sky laws), and in any underwriting involved therein, all the Registrable Securities specified
in a written request or requests, made within 20 days after the date of such written notice from
the Company, by any Holder subject to the limitations set forth in Section 5.2(b).



-6-









 





               (b) Underwriting. If the registration of which the Company gives notice is for a
registered public offering involving an underwriting, the Company shall so advise the Holders as a
part of the written notice given pursuant to Section 5.2(a)(i). In such event, the right of any
Holder to registration pursuant to Section 5.2 shall be conditioned upon such Holder’s
participation in such underwriting and the inclusion of Registrable Securities in the underwriting
shall be limited to the extent provided herein.



     All Holders proposing to distribute their securities through such underwriting shall (together
with the Company and the other Holders distributing their securities through such underwriting)
enter into an underwriting agreement in customary form with the managing underwriter selected for
such underwriting by the Company. Notwithstanding any other provision of this Section 5.2, if the
managing underwriter determines that marketing factors require a limitation of the number of shares
to be underwritten, the managing underwriter may limit the Registrable Securities to be included in
such registration (i) in the case of the Company’s initial public offering in which no other
selling stockholders participate, to zero, and (ii) in the case of any other offering, to an amount
no less than 25% of all shares to be included in such offering. The Company shall so advise all
Holders requesting to be included in the registration and underwriting and the number of shares of
Registrable Securities that may be included in the registration and underwriting shall be allocated
among all the Holders requesting to be included in the registration and underwriting in proportion,
as nearly as practicable, to the respective amounts of Registrable Securities held by them at the
time of filing the registration statement. To facilitate the allocation of shares in accordance
with the above provisions, the Company or the underwriters may round the number of shares allocated
to any Holder to the nearest 100 shares. If any Holder disapproves of the terms of any such
underwriting, such person may elect to withdraw therefrom by written notice to the Company.



               (c) Right to Terminate Registration. The Company shall have the right to terminate or
withdraw any registration initiated by it under this Section 5.2 prior to the effectiveness of such
registration whether or not any Holder has elected to include securities in such registration.



          5.3 Registration on Form S-3.




               (a) Request for Registration. In case the Company shall receive from the Holders of
at least 20% of the Registrable Securities a written request that the Company file a registration
statement on Form S-3 (or any successor form to Form S-3) for a public offering of shares of the
Registrable Securities the aggregate price to the public of which, net of underwriting discounts
and commissions, would equal or exceed $1,000,000, and the Company is a registrant entitled to use
Form S-3 to register the Registrable Securities for such an offering, the Company shall as soon as
practicable cause such Registrable Securities to be registered for the offering on such form and to
cause such Registrable Securities to be qualified in such jurisdictions as such Holder or Holders
may reasonably request. The Company shall inform the other Holders of the proposed registration
and offer them the opportunity to participate. In the event the registration is proposed to be
part of a firm commitment underwritten public offering, the substantive provisions of Section
5.1(b) shall be applicable to each such registration initiated under this Section 5.3.



-7-









 





               (b) Notwithstanding the foregoing, the Company shall not be obligated to take any action
pursuant to this Section 5.3:



                    (i) If the Company, within 30 days of the receipt of the written request of the Initiating
Holders, gives notice of its bona fide intention to effect the filing of a registration statement
with the Commission within 120 days of receipt of such request (other than with respect to a
registration statement relating to a Rule 145 transaction, an offering solely to employees or any
other registration which is not appropriate for the registration of Registrable Securities),
provided that the Company makes reasonable good faith efforts to complete such offering;



                    (ii) During the period starting with the date 60 days prior to the Company’s estimated date of
filing of, and ending on the date 180 days immediately following the effective date of, any
registration statement pertaining to securities of the Company (other than a registration of
securities in a Rule 145 transaction or with respect to an employee benefit plan), provided that
the Company is actively employing in good faith commercially reasonable efforts to cause such
registration statement to become effective;



                    (iii) More than two times during any 12-month period; or



                    (iv) If the Company shall furnish to the Holders initiating a request pursuant to this Section
5.3 a certificate signed by the President of the Company stating that, in the good faith judgment
of the Board of Directors, it would be detrimental to the Company or its stockholders for a
registration statement to be filed in the near future, then the Company’s obligation to file a
registration statement shall be deferred for a period not to exceed 120 days from the receipt of
the request to file such registration by such Holders, provided that the Company may not exercise
this deferral right more than once per 12 month period.



          5.4 Subsequent Registration Rights. From and after the date of this Agreement, the
Company shall not, without the prior written consent of the Holders of at least 70% of the
Registrable Securities, enter into any agreement with any holder or prospective holder of any
securities of the Company that would allow such holder or prospective holder to include such
securities in any registration filed under Section 5 hereof, unless the terms of such agreement
provide that such holder or prospective holder may include such securities in any such registration
only to the extent that the inclusion of such securities will not reduce the amount of the
Registrable Securities of the Holders that are included.




          5.5 Expenses of Registration. All Registration Expenses incurred in connection with
(i) two registrations pursuant to Section 5.1, (ii) all registrations pursuant to Section 5.2 and
(iii) all registrations pursuant to Section 5.3, shall be borne by the Company. Notwithstanding
the foregoing, in the event that Initiating Holders cause the Company to begin a registration
pursuant to Section 5.1 or Section 5.3, and the request for such registration is subsequently
withdrawn by the Initiating Holders or such registration is not completed due to failure to meet
the net proceeds requirement set forth in such section or is otherwise not successfully completed
due to no fault of the Company, all Holders shall be deemed to have forfeited their right to one
registration under Section 5.1 or a registration at the expense of the Company under Section 5.3,
as applicable, unless the Initiating Holders pay for, or reimburse the

-8-









 








Company for, the Registration Expenses incurred in connection with such withdrawn or
incomplete registration; provided, however, that if at the time of such withdrawal, the Holders
have learned of a material adverse change in the condition, business or prospects of the Company
from that known to the Holders at the time of their request and have withdrawn the request with
reasonable promptness following disclosure by the Company of such material adverse change, then the
Holders shall not be required to pay any of such expenses and shall retain their rights pursuant to
Section 5.1. Unless otherwise stated, all Selling Expenses relating to securities registered on
behalf of the Holders and all other registration expenses shall be borne by the Holders of such
securities pro rata on the basis of the number of shares so registered or proposed to be so
registered.




          5.6 Registration Procedures. In the case of each registration effected by the Company
pursuant to this Agreement, the Company will keep each Holder advised in writing as to the
initiation of such registration and as to the completion thereof. The Company will:




               (a) Prepare and file with the Commission a registration statement, the prospectus, and such
amendments and supplements as may be necessary and use commercially reasonable efforts to cause
such registration statement to become and remain effective for at least 120 days or until the
distribution described in the registration statement has been completed, whichever first occurs.



               (b) Furnish to the Holders participating in such registration and to the underwriters of the
securities being registered such reasonable number of copies of the registration statement,
preliminary prospectus, final prospectus and such other documents, including any amendment or
supplement to the prospectus, as such underwriters and Holders may reasonably request in order to
facilitate the public offering of such securities.



               (c) Use its best efforts to register and qualify the securities covered by such registration
statement under the securities laws of such jurisdictions as shall be reasonably appropriate for
the distribution of the securities covered by the registration statement, provided that the Company
shall not be required in connection therewith or as a condition thereto to qualify to do business
or to file a general consent to service of process in any such jurisdiction, and provided further
that (anything in this Agreement to the contrary notwithstanding with respect to the bearing of
expenses) if any jurisdiction in which the securities shall be qualified shall require that
expenses incurred in connection with the qualification of the securities in that jurisdiction be
borne by selling shareholders, then such expenses shall be payable by the selling Holders pro rata,
to the extent required by such jurisdiction if such Holders do not elect to withdraw from the
registration after notice of such requirement.



               (d) In the event of any underwritten public offering, enter into and perform its obligations
under an underwriting agreement with terms generally satisfactory to the managing underwriter of
such offering. Each Holder participating in such underwriting shall also enter into and perform
its obligations under such an agreement.



               (e) Notify each Holder of Registrable Securities covered by such registration statement at any
time when a prospectus relating thereto is required to be delivered under the Securities Act of the
happening of any event as a result of which the prospectus



-9-









 







included in such registration statement, as then in effect, includes an untrue statement of a
material fact or omits to state a material fact required to be stated therein or necessary to make
the statements therein not misleading in the light of the circumstances then existing.



               (f) Cause all such Registrable Securities registered hereunder to be listed on each securities
exchange on which similar securities issued by the Company are then listed.



               (g) Provide a transfer agent and registrar for all Registrable Securities registered pursuant
to such registration statement and a CUSIP number for all such Registrable Securities, in each case
not later than the effective date of such registration.



          5.7 Indemnification.




               (a) The Company will indemnify each Holder, each of its officers, directors, members and
partners, and each person controlling such Holder within the meaning of Section 15 of the
Securities Act, with respect to which registration has been effected pursuant to this Agreement,
against all expenses, claims, losses, damages or liabilities (or actions in respect thereof),
including any of the foregoing incurred in settlement of any litigation, commenced or threatened,
arising out of or based on any untrue statement (or alleged untrue statement) of a material fact
contained in any registration statement, prospectus, offering circular or other document, or any
amendment or supplement thereto, incident to any such registration, or based on any omission (or
alleged omission) to state therein a material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances in which they were made, not misleading,
or any violation by the Company of the Securities Act, the Exchange Act, state securities laws or
any rule or regulation promulgated under such laws applicable to the Company in connection with any
such registration, and the Company will reimburse each such Holder, each of its officers,
directors, members and partners, and each person controlling such Holder, for any legal and any
other expenses reasonably incurred, as such expenses are incurred, in connection with
investigating, preparing or defending any such claim, loss, damage, liability or action, provided
that the Company will not be liable in any such case to the extent that any such claim, loss,
damage, liability or expense arises out of or is based on any untrue statement or omission or
alleged untrue statement or omission, made in reliance upon and in conformity with written
information furnished to the Company by an instrument duly executed by such Holder or controlling
person, and stated to be specifically for use therein; provided, however, that the
foregoing indemnity agreement is subject to the condition that, insofar as it relates to any such
untrue statement, alleged untrue statement, omission or alleged omission made in a preliminary
prospectus on file with the Commission at the time the registration statement becomes effective or
the amended prospectus is filed with the Commission pursuant to Rule 424(b) (the “Final
Prospectus”), such indemnity agreement shall not inure to the benefit of any Holder, if a copy of
the Final Prospectus was not furnished to the person asserting the loss, liability, claim or damage
at or prior to the time such action is required by the Securities Act, and if the Final Prospectus
would have cured the defect giving rise to the loss, liability, claim or damage.



               (b) Each Holder will, if Registrable Securities held by such Holder are included in the
securities as to which such registration is being effected, indemnify the Company, each of its
directors and officers who have signed the registration statement, any other holders of



-10-









 







the Company’s securities covered by such registration statement, each person who controls the
Company within the meaning of Section 15 of the Securities Act, and any person who controls any
other holders of the Company’s securities covered by such registration statement within the meaning
of Section 15 of the Securities Act, against all claims, losses, damages and liabilities (or
actions in respect thereof) arising out of or based on any untrue statement (or alleged untrue
statement) of a material fact contained in any such registration statement, prospectus, offering
circular or other document, or any amendment or supplement thereto, incident to any such
registration, or based on any omission (or alleged omission) to state therein a material fact
required to be stated therein or necessary to make the statements therein, in light of the
circumstances in which they were made, not misleading, or any violation by the Holder of the
Securities Act, the Exchange Act, state securities laws or any rule or regulation promulgated under
such laws applicable to the Holder, and will reimburse the Company, such other Holders, such
directors, officers, or control persons for any legal or any other expenses reasonably incurred,
as such expenses are incurred, in connection with investigating or defending any such claim, loss,
damage, liability or action, but only to the extent that such untrue statement (or alleged untrue
statement) or omission (or alleged omission) is made in such registration statement, prospectus,
offering circular or other document in reliance upon and in conformity with written information
furnished to the Company by an instrument duly executed by such Holder, director, officer or
controlling person and stated to be specifically for use therein. Notwithstanding the foregoing,
the liability of each Holder under this subsection 5.7(b) shall be limited in an amount equal to
the net proceeds from the offering received by such Holder unless such liability arises out of or
is based on willful misconduct or fraud by such Holder.



               (c) Each party entitled to indemnification under this Section 5.7 (the “Indemnified Party”)
shall give notice to the party required to provide indemnification (the “Indemnifying Party”)
promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may
be sought, and shall permit the Indemnifying Party to assume the defense of any such claim or any
litigation resulting therefrom, provided that counsel for the Indemnifying Party, who shall conduct
the defense of such claim or litigation, shall be approved by the Indemnified Party (whose approval
shall not unreasonably be withheld), and the Indemnified Party may participate in such defense at
such party’s expense, and provided further that the failure of any Indemnified Party to give notice
as provided herein shall not relieve the Indemnifying Party of its obligations under this Agreement
unless the failure to give such notice is materially prejudicial to an Indemnifying Party’s ability
to defend such action and provided further, that the Indemnifying Party shall not assume the
defense for matters as to which there is a conflict of interest or there are separate and different
defenses. No Indemnifying Party, in the defense of any such claim or litigation, shall, except
with the consent of each Indemnified Party (whose consent shall not be unreasonably withheld),
consent to entry of any judgment or enter into any settlement which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a
release from all liability in respect to such claim or litigation.



               (d) If the indemnification provided for in this Section 5.7 is held by a court of competent
jurisdiction to be unavailable to an indemnified party with respect to any loss, liability, claim,
damage or expense referred to therein, then the indemnifying party, in lieu of indemnifying such
indemnified party hereunder, shall contribute to the amount paid or payable by such indemnified
party as a result of such loss, liability, claim, damage, or expense in such



-11-









 







proportion as is appropriate to reflect the relative fault of the indemnifying party on the
one hand and of the indemnified party on the other in connection with the statements or omissions
that resulted in such loss, liability, claim, damage or expense as well as any other relevant
equitable considerations; provided, that in no event shall any contribution by a Holder
under this Subsection 5.7(d) exceed the net proceeds from the offering received by such Holder,
except in the case of willful fraud by such Holder. The relative fault of the indemnifying party
and of the indemnified party shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission to state a material fact
relates to information supplied by the indemnifying party or by the indemnified party and the
parties’ relative intent, knowledge, access to information, and opportunity to correct or prevent
such statement or omission.



               (e) Notwithstanding the foregoing, to the extent that the provisions on indemnification and
contribution contained in the underwriting agreement entered into in connection with the
underwritten public offering are in conflict with the foregoing provisions, the provisions in the
underwriting agreement shall control.



          5.8 Information by Holder. The Holder or Holders of Registrable Securities included
in any registration shall furnish to the Company such information regarding such Holder or Holders,
the Registrable Securities held by them and the distribution proposed by such Holder or Holders as
the Company may reasonably request in writing and as shall be required in connection with any
registration referred to in this Agreement.




          5.9 Rule 144 Reporting. With a view to making available the benefits of certain rules
and regulations of the Commission which may at any time permit the sale of the Restricted
Securities to the public without registration, after such time as a public market exists for the
Common Stock of the Company, the Company agrees to:




               (a) Make and keep public information available, as those terms are understood and defined in
Rule 144 under the Securities Act, at all times after the effective date that the Company becomes
subject to the reporting requirements of the Securities Act or the Exchange Act;



               (b) File with the Commission in a timely manner all reports and other documents required of
the Company under the Securities Act and the Exchange Act (at any time after it has become subject
to such reporting requirements);



               (c) So long as a Holder owns any Restricted Securities, to furnish to the Holder forthwith
upon request a written statement by the Company as to its compliance with the reporting
requirements of said Rule 144 (at any time after 90 days after the effective date of the first
registration statement filed by the Company for an offering of its securities to the general
public), a copy of the most recent annual or quarterly report of the Company, and such other
reports and documents of the Company and other information in the possession of or reasonably
obtainable by the Company as the Holder may reasonably request in availing itself of any rule or
regulation of the Commission allowing the Holder to sell any such securities without registration;
and



-12-









 





               (d) Take such action, including the voluntary registration of its Common Stock under Section
12 of the Exchange Act, as is necessary to enable the Holders to utilize Form S-3 for the sale of
their Registrable Securities, such action to be taken as soon as practicable after the end of the
fiscal year in which the first registration statement filed by the Company for the offering of its
securities to the general public is declared effective.



          5.10 Termination of Registration Rights. The rights granted pursuant to Sections 5.1,
5.2 and 5.3 of this Agreement shall terminate as to any Holder upon the earlier of (i) seven years
after the Company’s initial public offering, or (ii) the date such Holder is eligible to sell all
of such Holder’s Registrable Securities under Rule 144 within any three month period.




     6. Financial Information; Inspection Rights.



          6.1 Financial Information. The Company will provide the following documents to each
Purchaser who, together with its affiliated funds, continues to hold at least 1,000,000 shares of
Preferred Stock and/or Conversion Stock (as adjusted for stock splits, stock dividends, stock
combinations and the like):




               (a) As soon as practicable after the end of each fiscal year thereafter, and in any event
within ninety (90) days after the end of each such fiscal year, balance sheets of the Company as of
the end of such fiscal year, and statements of operations and statements of cash flows and
stockholders’ equity of the Company, for such year, prepared in accordance with generally accepted
accounting principles and setting forth in each case in comparative form the figures for the
previous fiscal year, all in reasonable detail, which financial statements shall be accompanied by
a report and opinion thereon by independent public accountants of national standing selected by the
Company’s Board of Directors;



               (b) As soon as practicable after the end of each month and after the first, second and third
quarterly accounting periods in each fiscal year of the Company and in any event within 45 days
thereafter, a balance sheet of the Company as of the end of each such monthly or quarterly period,
and statements of operations and statements of cash flows of the Company for such period and for
the current fiscal year to date, prepared in accordance with generally accepted accounting
principles (other than accompanying notes), subject to changes resulting from year-end audit
adjustments, in reasonable detail and signed by the principal financial or accounting officer of
the Company; and



               (c) Annually, but in no event later than 10 days after adoption by the Board of Directors, and
promptly after any material amendment thereof, the operating plan and budget of the Company, in the
form approved by the Board of Directors, which plan shall include at least a projection of income
and cash flow for each fiscal quarter and such fiscal year and a projected balance sheet as of the
end of each fiscal quarter and the fiscal year.



          6.2 For purposes of determining the minimum holdings pursuant to this Section 6, any Purchaser
which is a partnership or limited liability company shall be deemed to hold any Preferred Stock
originally purchased by such Purchaser and subsequently distributed to constituent partners or
members of such Purchaser, but which have not been resold by such partners or members. If the
partnership or limited liability company is still in existence, the

-13-









 








Company may satisfy any obligation to distribute reports to individual partners of the
partnership or members of a limited liability company by delivering a single copy of each report to
the partnership or limited liability company as agent for the constituent partners or members.




          6.3 Inspection. The Company shall permit each Investor who holds at least 1,000,000
shares of Preferred Stock, at such Investor’s expense, to visit and inspect the Company’s
properties, to examine its books of account and records and to discuss the Company’s affairs,
finances and accounts with its officers, all at such reasonable times as may be requested by the
Investor; provided, however, that the Company shall not be obligated pursuant to this Section 6(c)
to provide access to any information which it reasonably considers to be a trade secret or similar
confidential information; it being understood and agreed, however, that no such limitation on an
Investor’s inspection right shall prevent an Investor from having access to the following: the
Company’s financial statements and records and any records relating to capitalization and corporate
governance of the Company.




          6.4 Each Purchaser or transferee of rights under this Section 6 acknowledges and agrees that
any information obtained pursuant to this Section 6 which may be considered nonpublic information
will be maintained in confidence by such Purchaser or transferee and will not be utilized by such
Purchaser or transferee in connection with purchases or sales of the Company’s securities except in
compliance with applicable state and Federal securities laws.




          6.5 The covenants of the Company set forth in this Section 6 shall terminate and be of no
further force or effect upon the closing of a firm commitment underwritten public offering of the
Company’s Common Stock or at such time as the Company is required to file reports pursuant to
Section 13 or 15(d) of the Exchange Act, whichever shall occur first.




     7. Lockup Agreement. Each Purchaser, Holder and transferee hereby agrees that, in
connection with the initial public offering of any securities of the Company under the Securities
Act for the account of the Company, if so requested by the Company or any representative of the
underwriters (the “Managing Underwriter”), such Purchaser, Holder or transferee shall not sell or
otherwise transfer any securities of the Company (except for those securities being registered,
those securities purchased in the initial public offering or those securities purchased in the
public market following the initial public offering) during the period specified by the Company’s
Board of Directors at the request of the Managing Underwriter (the “Market Standoff Period”), with
such period not to exceed 180 days following the effective date of such registration statement;
provided that officers, directors and holders of at least one percent (1%) of the Company’s voting
securities are bound by and have entered into similar agreements. The Company may impose
stop-transfer instructions with respect to securities subject to the foregoing restrictions until
the end of such Market Standoff Period.



     8. Right of First Refusal.



          8.1 The Company hereby grants to each Purchaser who continues to hold at least 1,000,000
shares of Preferred Stock and/or Conversion Stock (as adjusted for stock splits, stock dividends,
stock combinations and the like) (each such Purchaser referred to herein as a “Qualified
Purchaser”), the right of first refusal to purchase its Pro Rata Share of New Securities (as
defined in this Section 8) which the Company may, from time to time, propose to sell and

-14-









 








issue. A “Pro Rata Share,” for purposes of this right of first refusal, is the ratio that (i)
the sum of the number of shares of Common Stock then held by each Qualified Purchaser plus the
number of shares of Common Stock issuable upon conversion of the Preferred Stock and upon the
exercise or conversion of any securities exercisable or convertible, directly or indirectly, into
Common Stock, then held by such Qualified Purchaser bears to (ii) the sum of the total number of
shares of Common Stock then outstanding plus the number of shares of Common Stock issuable upon
exercise or conversion of all then outstanding securities exercisable for or convertible into,
directly or indirectly, Common Stock.




          8.2 Except as set forth below, “New Securities” shall mean any shares of capital stock of the
Company, including Common Stock and any series of preferred stock, whether now authorized or not,
and rights, options or warrants to purchase said shares of Common Stock or preferred stock, and
securities of any type whatsoever that are, or may become, convertible into or exchangeable for
said shares of Common Stock or preferred stock. Notwithstanding the foregoing, “New Securities”
does not include securities referred to as exceptions to the definition of “Additional Shares of
Common Stock” contained in sections 3(e)(iv)(i)—(vii) of the Company’s Sixth Amended and Restated
Certificate of Incorporation.




          8.3 In the event the Company proposes to undertake an issuance of New Securities, it shall
give each Qualified Purchaser written notice of its intention, describing the amount and type of
New Securities, and the price and terms upon which the Company proposes to issue the same. Each
Qualified Purchaser shall have fifteen (15) days from the date of receipt of any such notice to
agree to purchase up to its respective Pro Rata Share of such New Securities for the price and upon
the terms specified in the notice by giving written notice to the Company and stating therein the
quantity of New Securities to be purchased. An indication by a Qualified Purchaser to exercise its
rights of first refusal shall not be binding upon such Qualified Purchaser unless and until the
Company obtains binding commitments to purchase all of the securities specified in the notice of
the offering on the terms stated in such notice.




          8.4 Beginning fifteen (15) days after the notice given pursuant to Section 8(c) above, the
Company shall have 180 days to sell the New Securities not elected or eligible to be purchased by
Qualified Purchasers at the price and upon the terms no more favorable to the purchasers of such
securities than specified in the Company’s notice. In the event the Company has not sold all of
the New Securities within said 180 day period or offers the New Securities on substantially
different terms, the Company shall not thereafter issue or sell any New Securities without first
offering such securities in the manner provided above.




          8.5 The provisions of this Section 8 will terminate and be of no further force or effect upon
the closing of the Company’s initial public offering.




     9. Transfer of Rights. The rights granted under Sections 5, 6 and 8 of this Agreement
may be assigned to any transferee or assignee, other than a competitor or potential competitor of
the Company (as determined in good faith by the Company’s Board of Directors) in connection with
any transfer or assignment of Registrable Securities by the Holder, provided that: (i) such
transfer is otherwise effected in accordance with applicable securities laws and the terms of this
Agreement; (ii) such assignee or transferee acquires at least 300,000 shares (or all shares
held, if less, with respect to the rights granted under Section 5) (as adjusted for stock



-15-









 







splits,
stock dividends, stock combinations and the like) of Registrable Securities (including Preferred
Stock convertible into Registrable Securities), (iii) written notice is promptly given to the
Company; and (iv) such transferee or assignee agrees in writing to be bound by the provisions of
this Agreement. Subsection 9(ii) shall not apply to transfers to any of its affiliates (as such
term is defined in Rule 405 promulgated under the Securities Act), partner, member, beneficiary (in
the case of a trust), family member, trust for the benefit of family members, or family limited
partnership.



     10. Board Observer Right. The Company covenants and agrees that Granite Global
Ventures and its affiliates (“GGV”) shall be entitled to an observer who may be present at all
meetings of the Board of Directors, which designated representative shall receive copies of all
notice, minutes, consents and other materials that the Company provides to its directors at the
same time as such materials are provided to the directors, including telephonic board meetings;
provided, however, such designated representative of GGV may be excluded from any
meeting or portion thereof if the Company believes, upon advice of counsel, that such exclusion is
necessary to preserve attorney-client privilege, to protect highly confidential proprietary
information, for conflict of interest obligations, or for other similar reasons. GGV hereby agrees
that any proprietary information obtained by it and/or its designated representative in connection
with such observer’s attendance at board meetings shall be held in confidence and will not be
disclosed by GGV except to the extent otherwise required by law.



     11. Certain Covenants Relating to SBA Matters.



          11.1 Compliance. So long as any Investor which is a licensed Small Business
Investment Company (an “SBIC Investor”) holds any securities of the Company, the Company will at
all times comply with the non-discrimination requirements of 13 C.F.R. Parts 112, 113 and 117.




          11.2 Information for SBIC Investor. Within 45 days after the end of each fiscal year
and at such other times as an SBIC Investor may reasonably request, the Company shall deliver to
such SBIC Investor a written assessment, in form and substance satisfactory to such SBIC Investor,
of the economic impact of such SBIC Investor’s financing specifying the full-time equivalent jobs
created or retained in connection with such investment, and the impact of the financing on the
Company’s business in terms of profits and on taxes paid by the Company and its employees. Upon
request, the Company agrees to promptly provide each SBIC Investor with sufficient information to
permit such Investor to comply with its obligations under the Small Business Investment Act of
1958, as amended, and the regulations promulgated thereunder and related thereto; provided,
however, each SBIC Investor agrees that it will protect any information which the Company labels as
confidential to the extent permitted by law. Any submission of any financial information under
this Section shall include a certificate of the Company’s president, chief executive officer,
treasurer or chief financial officer.




          11.3 Number of Holders of Voting Securities. So long as any SBIC Investor holds any
securities purchased pursuant to the Purchase Agreement or issued by the Company with respect
thereto, the Company shall notify each SBIC Investor (i) at least 15 days prior to taking any
action after which the number of record holders of the Company’s voting securities would be
increased from fewer than 50 to 50 or more, and (ii) of any other action or occurrence




-16-









 







after which
the number of record holders of the Company’s voting securities was increased (or would increase)
from fewer than 50 to 50 or more, as soon as practicable after the Company becomes aware that such
other action or occurrence has occurred or is proposed to occur.




     12. Amendment. Except as otherwise provided herein, any provision of this Agreement
may be amended or the observance thereof may be waived (either generally or in a particular
instance and either retroactively or prospectively), only with the written consent of the Company
and the Holders of at least seventy percent (70%) of the then-outstanding shares of Preferred
Stock; provided, however, that any amendment of Section 10 shall require the approval of the
holders of at least seventy percent (70%) of the Series E Preferred Stock. Any amendment or waiver
effected in accordance with Section 5.4 or this Section 12, as applicable, shall be binding upon
each Purchaser, Holder of Registrable Securities at the time outstanding, each future holder of any
of such securities and the Company.



     13. Governing Law. This Agreement shall be governed in all respects by the internal
laws of the State of California without regard to conflict of laws provisions.



     14. Entire Agreement. This Agreement constitutes the full and entire understanding
and Agreement among the parties regarding the matters set forth herein and does hereby supersede
all other agreements of the parties relating to the subject matter hereof, including the Prior
Investor Rights Agreement. Except as otherwise expressly provided herein, the provisions hereof
shall inure to the benefit of, and be binding upon the successors, assigns, heirs, executors and
administrators of the parties hereto.



     15. Notices, etc. All notices and other communications required or permitted
hereunder shall be in writing and shall be mailed by registered or certified mail, postage prepaid,
delivered by a nationally recognized overnight courier, or sent by facsimile transmission, or by
