 2. Holder Registration. 
  
 (a) If at any time after the first anniversary of the Closing, the Company shall receive from any Holder or Holders who in
the aggregate hold not less than 50% of the outstanding Registrable Securities a written request that the Company effect any registration for the Registrable Securities, the Company will use commercially reasonable efforts to cause the Registrable
Securities held by the Holders to be registered under the Securities Act so as to permit the resale thereof, and in connection therewith shall prepare and file with the SEC within 60 days of its receipt of such request a registration statement on
such form as may then be available to effect the registration of the Registrable Securities. The offering made pursuant to such registration shall not be underwritten. 
  
 (b) The Company shall (i) prepare and file with the SEC the registration statement in accordance with Section 2 hereof with
respect to the Registrable Securities and shall use commercially reasonable efforts to cause such registration statement to become effective as promptly as practicable after filing and to keep such registration statement effective until the sooner
to occur of (A) the date on which all Registrable Securities included within such registration statement have been sold; (B) the date on which Holders of all Registrable Securities are able to sell such Registrable Securities immediately without
restriction pursuant to the volume limitation provisions of Rule 144 under the Securities Act within a single 90 day period, provided, however, that the Company shall provide each Holder with 10 trading days’ notice before
rescinding the effectiveness of such registration statement pursuant to this subparagraph 2(b)(i)(B); or (C) two years following the effective date of the registration statement; (ii) prepare and file with the SEC such amendments to such

documents, as such Holder may reasonably request in order to effect the offering and sale of the Registrable Securities to be offered and sold, but only while the Company shall be required under the provisions hereof to cause the registration
statement to remain effective; (iv) use commercially reasonable efforts to register or qualify the Registrable Securities covered by such registration statement under the securities or blue sky laws of such jurisdictions as each Holder shall
reasonably request (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 where it has not been
qualified), and do any and all other acts or things which may be necessary or advisable to enable each Holder to consummate the public sale or other disposition of such Registrable Securities in such jurisdictions; and (v) notify each Holder,
promptly after it shall receive notice thereof, of the date and time the registration statement and each post-effective amendment thereto has become effective or a supplement to any prospectus forming a part of such registration statement has been
filed; provided, further, that the Company shall not be obligated to take any action to effect any such registration, qualification or compliance pursuant to this Section 2 after the Company has effected one such registration pursuant to this
Section 2 and such registration has been declared or ordered effective. 
  

 -4- 








 (c) Notwithstanding subsection (b) above, if upon a termination of the effectiveness of the registration
statement pursuant to Section 2(b), any Holder(s) would not otherwise be able to sell all Registrable Securities then held by such Holder within a single 90-day period under Rule 144, the Company shall take such actions as may be necessary, whether
by filing a new registration statement or amending an existing registration statement, extend the effectiveness of such registration statement and keep such registration statement effective until such time as all such shares may be sold by such
Holder under Rule 144 within a single 90-day period. 
  
 3.
Piggyback Registration. 
  
 (a) The Company may from time
to time determine to register for sale shares of Common Stock for its own account, other than (i) a registration relating solely to employee benefit plans or (ii) a registration relating solely to a transaction pursuant to Rule 145 promulgated under
the Securities Act, and in connection with such determination, shall file with the SEC a registration statement to register such Common Stock (a “Registered Sale”). In the event of such determination, the Company will give to each
Holder written notice thereof at least 20 days (but not more than 60 days) prior to the filing of such registration statement, and will include in the Registered Sale (and any related qualification under blue sky laws or other related compliance)
all the Registrable Securities specified by the Holders in their written request or requests to the Company, made within 15 days after receipt of such written notice from the Company, subject, however, to the marketing limitation set forth in
subsection (b) below. If the registration statement under which the Company gives notice under this subsection (a) is for an underwritten offering, the Company shall so advise the Holders. A Registered Sale, including (if applicable) the form of
underwriting agreement to be entered into by the Company, the underwriter(s) and any selling stockholders, shall be on customary terms. The underwriter(s) for an underwritten offering shall be selected by the Company in its sole discretion.

  
 (b) The right of any Holder to registration pursuant to this
section shall be conditioned upon such Holder’s participation in the Registered Sale and the inclusion of Registrable Securities in the Registered Sale to the extent provided herein. All Holders shall (together with the Company and the other
holders distributing their securities through the Registered Sale) enter into an underwriting agreement in customary form with the managing underwriter. Notwithstanding any other provision of this section, 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 and underwriting; provided, however, that (i) all
shares that are not Registrable Securities and are held by other selling stockholders, including, without limitation, persons who are employees or directors of the Company (or any subsidiary of the Company), shall first be excluded from such
registration and underwriting before any Registrable Securities are so excluded (ii) all securities requested to be included by the Holders shall share pro rata in the number of shares to be excluded from such registration, such sharing to be based
on the respective numbers of shares owned by each stockholder and (iii) any such limitation shall not prevent the Holders of Registrable Securities requesting to be included in such registration from including Registrable Securities representing up
to 30% of the total number of shares registered thereby. In such event, the Company shall so advise all Holders of Registrable Securities which would otherwise be registered pursuant hereto, and the number of shares of Registrable Securities that
may be included in the registration shall be allocated among the Holders in proportion, as nearly 

  

 -5- 








 
as practicable, to the respective amounts of Registrable Securities requested to be included by such Holders in accordance with subsection (a) above. To
facilitate the allocation of shares in accordance with the above provision, 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 the Registered
Sale, he or she may elect to withdraw therefrom by written notice to the Company and the managing underwriter. If a Holder decides not to include all of its Registrable Securities in any registration statement filed by the Company, such Holder shall
nevertheless continue to have the right to include any Registrable Securities in any subsequent registration statement as may be filed by the Company, all upon the terms hereof. 
  
 (c) Termination of Piggyback Rights. Notwithstanding any other provision of this Agreement, the Company’s
obligations pursuant to this Section 3 shall terminate at such time as it has effected two (2) registrations in accordance herewith. 
  
 4. Right to Terminate Registration. The Company shall have the right to terminate or withdraw any registration initiated by it under Section 3
prior to the effectiveness of the registration whether or not any Holder has elected to include securities in such registration. 
  
 5. Notice to the Company; Suspension of Prospectus. Each Holder shall provide the compliance officer designated by the Company with written notice
at least two business days prior to any transfer, sale or other disposition of Registrable Securities under any registration statement filed pursuant to Section 2 of this Agreement (a “Requesting Holder”). The Company may by written
notice to such Requesting Holder delivered within two business days of receipt of such notice restrict the proposed offer, sale, transfer, or disposition of such Registrable Securities if the Company, in its reasonable judgment, has determined that
such transactions would require public disclosure by the Company of material non-public information that is not included in such registration. The notice referred to in the preceding sentence shall set forth the Company’s good faith estimate of
the number of days during which the Requesting Holder is to refrain from the proposed offer, sale, transfer of disposition of Registrable Securities. Upon receipt of such notice, the Requesting Holder agrees not to effect any offer, sale, transfer,
or other disposition of Registrable Securities pursuant to such registration statement for the period of days set forth in the Company’s notice. In the event the Requesting Holder is able to effect a transfer, sale or other disposition as
requested prior to the date the Company estimated, the Company shall provide an updated notice to the Requesting Holder. In any event, in the event of a delivery of the note described above by the Company, for a period of 15 trading days following
the expiration of the time period stated in the notice, a Holder may effect an offer, sale, transfer or other disposition of Registrable Securities without restriction under this Section 5. Notwithstanding the foregoing, the Company may not, without
the consent of the holders of a majority of the then-outstanding Registrable Securities, restrict the transfer, sale or other disposition of the Registrable Securities under any registration statement filed pursuant to this Agreement for more than
20 consecutive trading days or 90 trading days during any 365-day period.

 6. Indemnification. 
  
 (a) The Company will indemnify and hold harmless each Holder, each of its officers, directors, partners, members,
stockholders, legal counsel and any underwriter (as defined in the Securities Act) for the Holder, and each person controlling such Holder or underwriter within the meaning of Section 15 of the Securities Act, with respect to which registration,
qualification or compliance 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, qualification or compliance, 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 or the Exchange Act or any rule or regulation promulgated thereunder applicable to the Company or any state securities law applicable to the Company in
connection with any such registration, qualification or compliance, and the Company will reimburse (on an as incurred basis), each Holder, each of its officers, directors, partners, members, and each person controlling such Holder, for any
reasonable legal and other expenses incurred in connection with investigating, preparing or defending any such claim, loss, damage, liability or action; provided, however, 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 with regard to a
Holder furnished to the Company by such Holder for use by the Company in connection with a registration as required by Section 8 hereof; and provided further, however, that the Company will not be liable to any such person or
entity with respect to any such untrue statement or omission or alleged untrue statement or omission made in any preliminary prospectus that is corrected in the final prospectus filed with the SEC pursuant to Rule 424(b) promulgated under the
Securities Act (or any amendment or supplement to such prospectus) if the person asserting any such loss, claim, damage or liability purchased securities but was not sent or given a copy of the prospectus (as amended or supplemented) at or prior to
the written confirmation of the sale of such securities to such person in any case where such delivery of the prospectus (as amended or supplemented) is required by the Securities Act, unless such failure to deliver the prospectus (as amended or
supplemented) was a result of the Company’s failure to provide such prospectus (as amended or supplemented). 
  
 (b) Each Holder shall indemnify the Company, each of its directors and officers and each person who controls the Company 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 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, and will reimburse the Company and such directors, officers and partners and members, persons, or control persons of the Company for any reasonable legal or other expenses incurred in connection with investigating or defending any
such claim, loss, damage, liability or action, in each case to the 

  

 -7- 








 
extent, 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 with regard to the Holder furnished to the Company by such Holder for use by the Company in connection with a registration as
required by Section 8 hereof. The liability of a Holder under this Section 6(b) shall not exceed the proceeds from the offering received by such Holder, prior to deduction of any commissions, transfer taxes or other selling expenses incurred with
respect to such sale. 
  
 (c) Each party entitled to
indemnification under this Section 6 (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, however, that the failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Section 6 unless the failure to give such notice is materially
prejudicial to an Indemnifying Party’s ability to defend such action (and then only to the extent of such prejudice). No Indemnifying Party, in the defense of any such claim or litigation, shall, except with the consent of each Indemnified
Party, 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. Any Indemnified Party shall reasonably cooperate with the Indemnifying Party in the defense of any claim or litigation brought against such Indemnified Party. 
  
 (d) If the indemnification provided for in this Section 6 is for any reason not available 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 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 will as any other relevant equitable considerations. 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 the 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. The liability of a Holder under this Section 6(d) shall not exceed the proceeds from the offering received by such Holder less any amounts paid
pursuant to Section 6(b), prior to deduction of any commissions, transfer taxes or other selling expenses incurred with respect to such sale. 
  
 7. Expenses. The Company shall bear all Registration Expenses incurred in connection with (i) a registration declared effective by the SEC pursuant
to Section 2 here and (ii) of any registration, qualification or compliance pursuant to Section 3 hereof. All Selling Expenses relating 

  

 -8- 








 
to securities so registered shall be borne by the holders of such securities pro rata on the basis of the number of shares of securities so registered on
their behalf, provided, that any applicable taxes with respect to stock sold by a particular Holder shall be borne entirely by such Holder. 
  
 8. Information by Holder. Each Holder shall furnish to the Company such information regarding such Holder, the Registrable Securities held by it,
the manner in which such Holder holds any securities of the Company and the distribution proposed by such Holder as the Company may reasonably request in writing and as shall be reasonably required in connection with any registration, qualification
or compliance referred to in this Agreement. 
  
 9. Reports
Under the Exchange Act. With a view to making available to the Holders the benefits of Rule 144 and any other rule or regulation of the SEC that may at any time permit a Holder to sell securities of the Company to the public without
registration, the Company agrees to use commercially reasonable efforts to: 
  
 (a) make and keep public information available, as those terms are understood and defined in Rule 144, at all times after the date hereof; 
  
 (b) file with the SEC in a timely manner all reports and other documents required of the Company under the Securities Act
and the Exchange Act; and 
  
 (c) furnish to any Holder, so long
as the Holder owns any Registrable Securities, forthwith upon request (i) a written statement by the Company that it has complied with the reporting requirements of Rule 144, the Securities Act and the Exchange Act, (ii) a copy of the most recent
annual or quarterly report of the Company and such other reports and documents so filed by the Company, and (iii) such other information as may be reasonably requested to avail any Holder of any rule or regulation of the SEC that permits the selling
of any such securities without registration or pursuant to such form. 
  
 10. Limitation on Assignment of Registration Rights. The rights to cause the Company to register Registrable Securities pursuant to this Agreement may not be assigned or transferred, except that such right is assignable by each
Holder to (i) an “affiliate” of such Holder (as defined in Rule 12b-2 under the Exchange Act), or (ii) to a partner, active or retired of such Holder. As a condition to any permitted transfer hereunder, such transferee shall agree in
writing for the benefit of the Company to be bound by this Agreement. 
  
 11. Limitation on Subsequent Registration Rights. 
  
 (a) From and after the date of this Agreement, the Company shall not, without the prior written consent of the Holders of a majority of the Registrable Securities then outstanding, enter into any agreement with any holder or prospective
holder of any securities of the Company which would allow such holder or prospective holder (i) to include such securities in any registration filed under Section 2 or Section 3 hereof, unless under the terms of such agreement, such holder or
prospective holder may include such securities in any such registration only to the extent that the inclusion of his securities will not reduce the amount of the Registrable Securities of the Holders which are included, or (ii) to make a demand
registration which could result in such registration statement being declared effective prior to the date that is 120 days after the effective date of a registration effected pursuant to Section 2 hereof. 
  

 -9- 








 (b) Notwithstanding the foregoing, each Holder acknowledges and agrees that the Company has granted
Silicon Valley Bank pari passu registration rights pursuant to Section 3.3 of the Warrant to Purchase Stock dated as of June 16, 2003. Each Holder acknowledges and agrees that such registration rights shall remain effective after the date
hereof and hereby waives any breach, default, or other violation that may exist under the Prior Agreement in connection with the grant of such registration rights and any remedy or remedies that may exist with respect thereto. 
  
 12. Right of Participation. The Company hereby grants to each
Significant Holder the right to purchase its pro rata share of any New Securities which the Company may, from time to time, propose to sell and issue. A Significant Holder’s pro rata share, for purposes of this right of participation, is the
ratio that the number of shares of Common Stock issued or issuable upon conversion of the Series A Preferred Stock or the Series A-2 Preferred Stock owned by such Significant Holder immediately prior to the issuance of New Securities, bears to the
total number of shares of Common Stock outstanding as reported in the Company’s most recent Form 10-K or Form 10-Q, as the case may be, filed with the SEC under the Exchange Act. This right to participate shall be subject to the following
provisions: 
  
 (a) In the event the Company proposes to
undertake an issuance of New Securities, it shall give each Significant Holder written notice of its bona fide intention, describing the type of New Securities, and their price and the general terms upon which the Company proposes to issue the same.
Each Significant Holder shall have ten days after any such notice is effective as determined pursuant to Section 21(b) hereof to agree to purchase such Significant Holder’s 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. 
  
 (b) In the event the Significant Holders fail to exercise fully the right to participate within said ten day period, the Company shall have 90 days
thereafter to sell or enter into an agreement (pursuant to which the sale of New Securities covered thereby shall be closed, if at all, within 30 days from the date of said agreement) to sell the New Securities respecting which the Significant
Holders’ right to participate set forth herein was not exercised, at a price and upon terms no more favorable to the purchasers thereof than specified in the Company’s notice to Significant Holders pursuant to subsection (a) above. In the
event the Company has not sold within such 90 day period or entered into an agreement to sell the New Securities in accordance with the foregoing within 30 days from the date of said agreement, the Company shall not thereafter issue or sell any New
Securities, without first again offering such securities to the Significant Holders in the manner provided in subsection (a) above. 
  
 (c) Each Significant Holder (as constituted pursuant to the Prior Agreement) hereby waives the application of this provision pursuant to the Prior
Agreement, and waives all applicable notice provisions relating thereto, in connection with the sale and issuance of Series A-2 Preferred pursuant to the 2003 Purchase Agreement. 
  

 -10- 








 13. Limitation on Assignment of Right to Participate. The rights of the Significant Holders to
participate in sales of New Securities may not be assigned or transferred, except that such right is assignable by each Significant Holder to (i) an “affiliate” of such Significant Holder (as defined in Rule 12b-2 under the Exchange Act)
or (ii) to a partner (active or retired), parent, child or spouse of such Holder, or to a trust for the direct or indirect benefit of any of the foregoing, provided, that in the case of either (i) or (ii) such transferee together with its
affiliates holds after such transfer at least 66,667 shares of Series A Preferred Stock or 50,000 shares of Series A-2 Preferred Stock or at least the number of shares of Common Stock as were issued upon conversion of 66,667 shares of Series A
Preferred Stock or 50,000 shares of Series A-2 Preferred Stock (subject, in each case, to adjustments for stock splits, stock dividends, reverse stock splits and the like). 
  
 14. Termination of Right to Participate. The rights of the Significant Holders to participate in sales of New
Securities shall terminate upon the earlier of (i) the second anniversary of this Agreement, or (ii) when such Holder ceases to be a Significant Holder. 
  
 15. Transfer Restrictions of the Series A Preferred Stock and the Registrable Securities. Each Holder further agrees not to sell or otherwise make
any disposition or transfer of all or any portion of the Registrable Securities held by such Holder except (i) to an “affiliate” of such Holder (as defined in Rule 12b-2 under the Exchange Act), or (ii) to a partner (active or retired),
parent, child or spouse of such Holder, or to a trust for the direct or indirect benefit of any of the foregoing (and in each case under subsection (i) and (ii) hereof, as a condition to transfer, such transferee shall agree in writing for the
benefit of the Company to be bound by this Agreement), or unless: 
  
 (a) There is then in effect a registration statement under the Securities Act covering such proposed disposition and such disposition is made in accordance with such registration statement; or 
  
 (b) Such Holder shall have notified the Company of the proposed disposition
and shall have furnished the Company with a detailed statement of the circumstances surrounding the proposed disposition, and, such Holder shall have furnished the Company with an opinion of counsel, reasonably satisfactory to the Company, that such
disposition will not require registration of such shares under the Securities Act. 
  
 Notwithstanding the foregoing, a Holder may, without restriction, transfer all or any portion of such Holder’s Registrable Securities (i) pursuant to a statutory merger or statutory consolidation of the Company
with or into another corporation or corporations in which the stockholders of the Company receive distributions in cash or securities of another entity or entities as a result of such transaction, and in which the stockholders of the Company,
immediately prior to such merger or consolidation hold, immediately after such merger or consolidation, less than a majority of the outstanding voting securities of the surviving or successor corporation or its parent, (ii) pursuant to the winding
up and dissolution of the Company, (iii) pursuant to a registration effected in accordance with Section 2 or Section 3 hereof, or (iv) in compliance with Rule 144. 
  
 16. Restrictive Legends. Each certificate representing Registrable Securities shall (unless otherwise permitted by
the provisions of this Agreement) be stamped or otherwise imprinted with a 

  

 -11- 








 
legend substantially similar to the following (in addition to any legend required under applicable state securities laws): 
  
 THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933 (THE “ACT”) AND MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER THE ACT OR, IN THE OPINION OF COUNSEL SATISFACTORY TO THE ISSUER OF THESE
SECURITIES, SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION OTHERWISE COMPLIES WITH THE ACT. 
  
 COPIES OF THE AGREEMENT COVERING THE PURCHASE OF THESE SHARES AND RESTRICTING THEIR VOTING AND TRANSFER MAY BE OBTAINED AT NO COST BY WRITTEN REQUEST MADE
BY THE HOLDER OF RECORD OF THIS CERTIFICATE TO THE SECRETARY OF THE COMPANY AT THE PRINCIPAL EXECUTIVE OFFICE OF THE COMPANY. 
  
 17. Market Stand-Off Agreement. Each Investor and Prior Investor and any permitted transferee hereunder agrees, in connection with the first
registration of the Company’s securities in connection with an underwritten public offering following the date hereof, upon request of the Company or the underwriters managing any underwritten offering of the Company’s securities, not to
sell, make any short sale of, loan, grant any option for the purchase of or otherwise dispose of any securities of the Company without the prior written consent of the Company or such underwriters, as the case may be, for such period of time (not to
exceed 180 days) from the effective date of such registration as the Company or the underwriters may specify; provided that (i) all officers and directors of the Company then holding capital stock of the Company and (ii) all stockholders holding in
the aggregate at least 5% of the fully-diluted equity of the Company are bound by similar agreements. The foregoing restriction shall not apply to any securities of the Company held by an Investor or Prior Investor that are included in such
registration. Each Investor and Prior Investor agrees that the Company may instruct its transfer agent to place stop-transfer notations in its records to enforce the provisions of this Section. This Section 17 shall not apply to the sale of any
shares to an underwriter pursuant to an underwriting agreement. Notwithstanding any other provision of this Agreement, the Company may assign the obligations of each Investor or Prior Investor under this Section 17 to any underwriter of the
Company’s securities. 
  

 -12- 








 18. Covenant Against Indebtedness. The Company agrees, that prior to December 19, 2005, the
approval of the Holders of two-thirds of the then outstanding “Investor Securities” (as defined below) will be required for: (i) any debt financing, including convertible debt financings, in excess of $750,000, in the aggregate, other than
(a) financing for the purchase or lease of capital equipment that is secured by the capital equipment, (b) accounts receivable financing that is secured by the accounts receivable of the Company, (c) normal trade debt, or (d) borrowings under the
Loan and Security Agreement dated as of June 16, 2003 between the Company and Silicon Valley Bank (the “Loan Agreement”); or (ii) any grant of a security interest in the intellectual property of the Company. “Investor
Securities” shall mean the Series A Preferred Stock and Series A-2 Preferred Stock issued pursuant to the 2002 Purchase Agreement and 2003 Purchase Agreement, respectively, and any Common Stock issued upon conversion thereof, or as a
dividend, distribution, exchange or replacement in respect thereof; provided, however, that “Investor Securities” shall not include any shares of Common Stock that are transferred to a person or entity that is not an
“Investor” under the 2002 Purchase Agreement or the 2003 Purchase Agreement or a partner (including former partners) or affiliate of the same. Each holder of Investor Securities hereby waives any breach, default, or other violation that
may exist under the Prior Agreement with respect to the Loan Agreement and any remedy or remedies that may exist with respect thereto. 
  
 19. Negative Covenants. 
  
 (a) The Company agrees that the approval of the Holders of two-thirds of the then outstanding A-2 Securities will be required to (i) increase to the
number of shares designated by the Company’s Certificate of Designation as Series A-2 Preferred Stock; (ii) designate, authorize, or issue, or obligate itself to designate, authorize, or issue, any equity security (including any other security
convertible into or exercisable for any such equity security) having a preference over, or being on a parity with, the Series A-2 Preferred Stock with respect to dividends, liquidation or redemption (other than issuances of Series A-2 Preferred
Stock pursuant to the 2003 Purchase Agreement or in accordance with the Rights Offering (as defined in the 2003 Purchase Agreement)); (iii) pay any dividend or make any distribution upon any share or shares of Preferred Stock or Common Stock of the
Company; (iv) redeem, purchase or otherwise acquire (or pay into or set aside for a sinking fund for such purpose) any share or shares of Preferred Stock or Common Stock of the Company; provided, however, that this restriction shall
not apply to the repurchase of shares of Common Stock from employees, officers, directors, consultants or other persons performing services for this corporation or any subsidiary pursuant to agreements under which the Company has the option to
repurchase such shares upon the occurrence of certain events, such as the termination of employment or service, or pursuant to a right of first refusal. 
  
 (b) “A-2 Securities” shall mean shares of Series A-2 Preferred Stock issued pursuant to the 2003 Purchase Agreement. 
  
 (c) The Company acknowledges and agrees that it would be impossible to
measure in money the damages a holder of A-2 Securities may incur in the event the Company fails to comply with its obligations under this Section 19, and in the event of such failure to comply, a holder of A-2 Securities will not have an adequate
remedy at law for damages. Accordingly, with respect only to compliance with this Section 19, the Company hereby agrees that injunctive relief or other equitable relief, in addition to remedies at law for damages, is the appropriate remedy for any


  

 -13- 








 
such failure, and the Company will not oppose the granting of such relief on the basis that such holders have an adequate remedy at law. 
  
 20. Covenant About Investment Advisors Act. The Company agrees that it
will take such actions as may from time to time be necessary to insure that the Company does not become subject to the Investment Advisors Act of 1940, as amended. 
  
 21. Miscellaneous. 
  
 (a) Third Parties. Nothing in this Agreement, express or implied, is intended to confer upon any party, other than the parties to this Agreement,
and their respective successors and assigns, any rights, remedies, obligations or liabilities under or by reason of this Agreement. 
  
 (b) Governing Law. This Agreement shall be construed in accordance with, and governed in all respects by, the laws of the State of California,
regardless of the laws that might otherwise govern under applicable principles of conflicts of laws thereof. With respect to any disputes arising out of or related to this Agreement, the parties consent to the exclusive jurisdiction of, and venue
in, the state courts in the County of Santa Clara in the State of California (or in the event of exclusive federal jurisdiction, the courts of the Northern District of California). 
  
 (c) Severability. If one or more provisions of this Agreement are held to be unenforceable under applicable law,
portions of such provisions, or such provisions in their entirety, to the extent necessary, shall be severed from this Agreement, and the balance of this Agreement shall be enforceable in accordance with its terms. 
  
 (d) Notices. All notices and other communications required or
permitted hereunder shall be in writing and shall be mailed by registered or certified mail, postage prepaid, sent by facsimile, or otherwise delivered by hand or by messenger addressed:

 (ii)

 Each such notice or other communication shall for

for the deposit of the United States mail, addressed and mailed as aforesaid or, if sent by facsimile, upon confirmation of facsimile transfer. Any party may amend its address for receipt of notice by delivering written instructions to the other
party in accordance with this Section 21(d).

 (e) Amendment and Waiver. This Agreement may be amended, or any provision waived, only upon the
written consent of the Company and two-thirds in interest of the Holders, provided, however, that any amendment to, or waiver under, (i) Sections 12, 13 or 14 shall require the written consent of the Company and a majority-in-interest
of the Significant Holders; (ii) Section 18 shall require the written consent of the Company and holders of two-thirds of the then-outstanding Investor Securities; and (iii) Section 19 shall require the written consent of holders of two-thirds of
the then-outstanding A-2 Securities; and provided further, however, that any amendment adversely affecting one or more Holders or Significant Holders, as applicable, that does not so affect all Holders or Significant Holders, as
applicable, shall require the written consent of such adversely affected Holder or Significant Holder. Each of the parties hereto acknowledges and agrees that the Company proposes to issue and sell additional shares of Series A-2 Preferred Stock
pursuant to the 2003 Purchase Agreement and that any such purchaser of such Series A-2 Preferred Stock shall become a Holder pursuant to this Agreement and a party hereto upon execution of an additional signature page by the Company and such
purchaser, without any requirement on the part of the Company to seek consent or approval of the Holders. 
  
 (f) Confidentiality. Anything in this Agreement to the contrary notwithstanding, no Holder by reason of this Agreement shall have access to any
trade secrets or classified information of the Company. Each Holder acknowledges that the information received by them pursuant to this Agreement may be confidential and for its use only, and it will not use such confidential information in
violation of the Exchange Act or reproduce, disclose or disseminate such information to any other person (other than its employees or agents having a need to know the contents of such information who are subject to confidentiality obligations to
such Holder, and its attorneys), except in connection with the exercise of rights under this Agreement, unless the Company has made such information available to the public generally or such Holder is required to disclose such information by a
governmental authority. 
  
 (g) Counterparts. This
Agreement may be executed in counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. 
  
 (h) Telecopy Execution and Delivery. A facsimile, telecopy or other reproduction of this Agreement may be executed by
one or more parties hereto, and an executed copy of this Agreement may be delivered by one or more parties hereto by facsimile or similar electronic transmission device pursuant to which the signature of or on behalf of such party can be seen, and
such execution and delivery shall be considered valid, binding and effective for all purposes. At the request of any party hereto, all parties hereto agree to execute an original of this Agreement as well as any facsimile, telecopy or other
reproduction hereof.
