          SECTION 3. EXERCISE OF THE PURCHASE RIGHTS.

     (a) Exercise. The purchase rights set forth in this Agreement are exercisable by the Warrantholder, for all or any part of the Warrant Coverage, at any time, or from time to time, prior to the expiration of the term set forth in Section 2, by tendering to the Company at its then principal executive offices this Agreement and a notice of exercise in the form attached hereto as Exhibit I (the “Notice of Exercise”), duly completed and executed and payment in full of the Purchase Price in accordance with the terms set forth below. Promptly upon receipt of the Notice of Exercise and the payment of the Purchase Price in accordance with the terms set forth below, and in no event later than five (5) Business Days thereafter, the Company shall issue to the Warrantholder a certificate for the number of shares of Preferred Stock purchased and shall execute the acknowledgment of exercise in the form attached hereto as Exhibit II (the

“Acknowledgment of Exercise”) indicating the Warrant Coverage amount which remains subject to future purchases, if any.

     The Purchase Price may be paid at the Warrantholder’s election either (i) by cash or check, or (ii) by surrender of all or a portion of the Warrant for shares of Preferred Stock to be exercised under this Agreement and, if applicable, an amended Agreement representing the remaining number of shares purchasable hereunder, as determined below (“Net Issuance”). If the Warrantholder elects the Net Issuance method, the Company will issue Preferred Stock in accordance with the following formula:

		X =		Y(A-B)        A

Where:		X =		the number of shares of Preferred Stock to be issued to the Warrantholder.
				Y = the number of shares of Preferred Stock requested to be exercised under this Agreement.
				A = the fair market value of one (1) share of Preferred Stock at the time of issuance of such shares of Preferred Stock.
		B =		the Exercise Price.

     For purposes of the above calculation, current fair market value of Preferred Stock shall mean with respect to each share of Preferred Stock:

     (i) if the exercise is in connection with an Initial Public Offering, and if the Company’s Registration Statement relating to such Initial Public Offering has been declared effective by the SEC and the Initial Public Offering has closed, then the fair market value per share shall be the product of (x) the initial “Price to Public” of the Common Stock specified in the final prospectus with respect to the offering and (y) the number of shares of Common Stock into which each share of Preferred Stock is convertible at the time of such exercise;

     (ii) if the exercise is after, and not in connection with an Initial Public Offering, and:

     (A) if the Common Stock is traded on a securities exchange, the fair market value shall be deemed to be the product of (x) the average of the closing prices over a five (5) day period ending three days before the day the current fair market value of the securities is being determined and (y) the number of shares of Common Stock into which each share of Preferred Stock was convertible at the time of the Initial Public Offering; or

     (B) if the Common Stock is traded over-the-counter, the fair market value shall be deemed to be the product of (x) the average of the closing bid and asked prices quoted on the NASDAQ system (or similar system) over the five (5) day period ending three days before the day the current fair market value of the securities is being determined and (y) the number of shares of Common Stock into which each share of Preferred Stock was convertible at the time of the Initial Public Offering;

     (iii) if at any time the Common Stock is not listed on any securities exchange or quoted in the NASDAQ National Market or the over-the-counter market, the current fair market value of Preferred Stock shall be the product of (x) the highest price per share which the Company could obtain from a willing buyer (not a current employee or

director) for shares of Common Stock sold by the Company, from authorized but unissued shares, as determined in good faith by its Board of Directors, unless the Company shall become subject to a Merger Event, in which case the fair market value of Preferred Stock shall be deemed to be the per share value received by the holders of the Company’s Preferred Stock on a common equivalent basis pursuant to such Merger Event, and (y) the number of shares of Common Stock into which each share of Preferred Stock is convertible at the time of such exercise; provided, however, that if such exercise occurs on or after the time of a Conversion Event, the number of shares of Common Stock into which each share of Preferred Stock is converted shall be the number of shares of Common Stock into which each share of Preferred Stock was convertible at the time of the Conversion Event.

     Upon partial exercise of the Warrant, the Company shall promptly issue an amended Agreement representing the remaining Warrant Coverage hereunder. All other terms and conditions of such amended Agreement shall be identical to those contained herein, including, but not limited to the Effective Date hereof.

     (b) Exercise Prior to Expiration. To the extent this Agreement is not previously exercised as to all Preferred Stock subject hereto, and if the fair market value of one share of the Preferred Stock is greater than the Exercise Price then in effect, this Agreement shall be deemed automatically exercised pursuant to Section 3(a) (even if not surrendered) immediately before its expiration. For purposes of such automatic exercise, the fair market value of one share of the Preferred Stock upon such expiration shall be determined pursuant to Section 3(a). To the extent this Agreement or any portion thereof is deemed automatically exercised pursuant to this Section 3(b), the Company agrees to promptly notify the Warrantholder of the number of shares of Preferred Stock, if any, the Warrantholder is to receive by reason of such automatic exercise.

          SECTION 4. RESERVATION OF SHARES.

     During the term of this Agreement, the Company will at all times have authorized and reserved a sufficient number of shares of its Preferred Stock to provide for the exercise of the rights to purchase Preferred Stock as provided for herein, and shall have authorized and reserved a sufficient number of shares of its Common Stock to provide for the conversion of the Preferred Stock available hereunder; provided, however, that if at any time the number of authorized but unissued shares of Preferred Stock or Common Stock shall not be sufficient or shall not be sufficient to effect the conversion of the Preferred Stock available hereunder, the Company shall take such corporate action as may be necessary to increase its authorized but unissued shares of Preferred Stock or Common Stock, as applicable, to such number of shares as shall be sufficient for such purposes, including, without limitation, engaging in commercially reasonable best efforts to obtain the requisite stockholder approval of the necessary amendment to the Certificate of Incorporation.

          SECTION 5. NO FRACTIONAL SHARES OR SCRIP.

     No fractional shares or scrip representing fractional shares shall be issued upon the exercise of this Agreement, but in lieu of such fractional shares the Company shall make a cash payment therefor upon the basis of the Exercise Price then in effect.

          SECTION 6. NO RIGHTS AS SHAREHOLDER/STOCKHOLDER.

     This Agreement does not entitle the Warrantholder to any voting rights or other rights as a stockholder of the Company prior to the exercise of this Agreement.

          SECTION 7. WARRANTHOLDER REGISTRY.

     The Company shall maintain a registry showing the name and address of the registered holder of this Agreement. Warrantholder’s initial address, for purposes of such registry, is set forth below Warrantholder’s signature on this Agreement. Warrantholder may change such address by giving written notice of such changed address to the Company.

          SECTION 8. ADJUSTMENT RIGHTS.

     The Exercise Price and the number of shares of Preferred Stock purchasable hereunder are subject to adjustment, as follows:

     (a) Merger Event. If at any time there shall be Merger Event, then, as a part of such Merger Event, lawful provision shall be made so that the Warrantholder shall thereafter be entitled to receive, upon exercise of this Agreement, the number of shares of preferred stock or other securities or property of the successor corporation resulting from such Merger Event that would have been issuable if Warrantholder had exercised this Agreement immediately prior to the Merger Event. In any such case, appropriate adjustment (as determined in good faith by the Company’s Board of Directors) shall be made in the application of the provisions of this Agreement with respect to the rights and interests of the Warrantholder after the Merger Event to the end that the provisions of this Agreement (including adjustments of the Exercise Price and number of shares of Preferred Stock purchasable) shall be applicable in their entirety, and to the greatest extent possible. Without limiting the foregoing, in connection with any Merger Event, upon the closing thereof, the successor or surviving entity shall assume the obligations of this Agreement. Notwithstanding anything to the contrary contained herein, with respect to any Merger Event, the Warrantholder shall have the right to elect prior to the consummation of such Merger Event, to give effect to the exercise rights contained in Section 3 of this Agreement instead of giving effect to the provisions contained in this Section 8(a) with respect to this Warrant.

     (b) Reclassification of Shares. Except as set forth in Section 8(a), if the Company at any time shall, by combination, reclassification, exchange or subdivision of securities or otherwise, change any of the securities as to which purchase rights under this Agreement exist into the same or a different number of securities of any other class or classes, this Agreement shall thereafter represent the right to acquire such number and kind of securities as would have been issuable as the result of such change with respect to the securities which were subject to the purchase rights under this Agreement immediately prior to such combination, reclassification, exchange, subdivision or other change.

     (c) Subdivision or Combination of Shares. If the Company at any time shall combine or subdivide its Preferred Stock, (i) in the case of a subdivision, the Exercise Price shall be proportionately decreased, or (ii) in the case of a combination, the Exercise Price shall be proportionately increased.

     (d) Stock Dividends. If the Company at any time while this Agreement is outstanding and unexpired shall:

     (i) pay a dividend with respect to the Preferred Stock payable in Preferred Stock, then the Exercise Price shall be adjusted, from and after the date of determination of stockholders entitled to receive such dividend or distribution, to that price determined by multiplying the Exercise Price in effect immediately prior to such date of determination by a fraction (A) the numerator of which shall be the total number of shares of Preferred Stock outstanding immediately prior to such dividend or distribution, and (B) the denominator of which shall be the total number of shares of Preferred Stock outstanding immediately after such dividend or distribution; or

     (ii) make any other distribution with respect to Preferred Stock (or stock into which the Preferred Stock is convertible), except (i) any distribution specifically provided for in any other clause of this Section 8 and (ii) any accruing dividends set forth in Article FOURTH, Section B. 1. of the Company’s Charter or any comparable provision contained in the Company’s Charter for any other series of Preferred Stock issued after the Effective Date (“Accruing Dividends”), then, in each such case, provision shall be made by the Company such that the Warrantholder shall receive upon exercise or conversion of this Warrant a proportionate share of any such distribution as though it were the holder of the Preferred Stock (or other stock for which the Preferred Stock is convertible) as of the record date fixed for the determination of the stockholders of the Company entitled to receive such distribution.

     (e) Antidilution Rights. The Company shall promptly provide the Warrantholder with any restatement, amendment, modification or waiver of the Charter. The Company shall provide Warrantholder with prior written notice of any Subsequent Round to occur after the Effective Date of this Agreement, which notice shall include (a) the price at which such stock or security is to be sold, (b) the number of shares to be issued, and (c) such other information as necessary for Warrantholder to determine if a dilutive event has occurred.

     (f) Notice of Adjustments. If: (i) the Company shall declare any dividend or distribution upon its stock, whether in stock, cash, property or other securities (and until termination of the Loan Agreement, assuming Warrantholder consents to a dividend involving cash as contemplated by Section 7.7 of the Loan Agreement); (ii) the Company shall offer for subscription prorata to the holders of any class of its Preferred Stock or other convertible stock any additional shares of stock of any class or other rights; (iii) there shall be any Merger Event; (iv) there shall be an Initial Public Offering; (v) the Company shall sell, lease, license or otherwise transfer all or substantially all of its assets; or (vi) there shall be any voluntary dissolution, liquidation or winding up of the Company; then, in connection with each such event, the Company shall send to the Warrantholder: (A) at least twenty (20) days’ prior written notice of the date on which the books of the Company shall close or a record shall be taken for such dividend, distribution, subscription rights (specifying the date on which the holders of Preferred Stock shall be entitled thereto) or for determining rights to vote in respect of such Merger Event, dissolution, liquidation or winding up; (B) in the case of any such Merger Event, sale, lease, license or other transfer of all or substantially all assets, dissolution, liquidation or winding up, at least twenty (20) days’ prior written notice of the date when the same shall take place (and specifying the date on which the holders of Preferred Stock shall be entitled to exchange their Preferred Stock for securities or other property deliverable upon such Merger Event, dissolution, liquidation or winding up); and (C) in the case of an Initial Public Offering, the Company shall give the Warrantholder at least twenty (20) days’ written notice prior to the effective date thereof.

     Each such written notice shall set forth, in reasonable detail, (i) the event requiring the notice, and (ii) if any adjustment is required to be made, (A) the amount of such adjustment, (B) the method by which such adjustment was calculated, (C) the adjusted Exercise Price (if the Exercise Price has been adjusted), and (D) the number of shares subject to purchase hereunder after giving effect to such adjustment, and shall be given by first class mail, postage prepaid, or by reputable overnight courier with all charges prepaid, addressed to the Warrantholder at the address for Warrantholder set forth in the registry referred to in Section 7.

     (g) Timely Notice. Failure to timely provide such notice required by subsection (f) above shall entitle Warrantholder to retain the benefit of the applicable notice period notwithstanding anything to the contrary contained in any insufficient notice received by Warrantholder. For purposes of this subsection (g), the notice period shall begin on the date Warrantholder receives a

written notice in accordance with Section 12(g) containing all the information required to be provided in such subsection (f).

     SECTION 9. REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE COMPANY.

     (a) Reservation of Preferred Stock.

be entitled to the information rights contained in Section 7.1 of the Loan Agreement, and Section 7.1 of the Loan Agreement is hereby incorporated into this Agreement by this reference as though fully set forth herein, provided, however, that the Company shall not be required to deliver a Compliance Certificate once all Indebtedness (as defined in the Loan Agreement) owed by the Company to Warrantholder has been repaid. Notwithstanding anything to the contrary contained herein, only Hercules Technology Growth Capital, Inc. and its Affiliates shall be entitled to the rights set forth in this Section 9(i) for so long as Warrantholder or an Affiliate is a Warrantholder and no other assignee or transferee of this Warrant or any of the rights hereunder shall be entitled to the information rights set forth in this Section 9(i).

     SECTION 10. REPRESENTATIONS AND COVENANTS OF THE WARRANTHOLDER.

     This Agreement has been entered into by the Company in reliance upon the following representations and covenants of the Warrantholder:

     (a) Investment Purpose. The right to acquire Preferred Stock or the Preferred Stock issuable upon exercise of the Warrantholder’s rights contained herein or the Common Stock issuable upon conversion of the Preferred Stock will be acquired for investment for the Warrantholder’s own account and not with a view to the sale or distribution of any part thereof, and the Warrantholder has, and at the time of exercise will have, no present intention of selling or engaging in any public distribution of the same except pursuant to registration or exemption under the Act.

     (b) Private Issue. The Warrantholder understands (i) that the Preferred Stock (and the Common Stock issuable upon conversion of the Preferred Stock) issuable upon exercise of this Agreement is not registered under the Act or qualified under applicable state securities laws on the ground that the issuance contemplated by this Agreement will be exempt from the registration and qualifications requirements thereof, (ii) that this Warrant and the Preferred Stock (and the Common Stock issuable upon conversion of the Preferred Stock) to be issued upon exercise hereof are “restricted securities” under the federal securities laws inasmuch as they are being acquired from the Company in a transaction not involving a public offering and that, under such laws and applicable regulations, such securities may be resold without registration under the Act only in certain limited circumstances, and (iii) that the Company’s reliance on such exemption is predicated on the representations set forth in this Section 10.

     (c) Financial Risk. The Warrantholder has such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of its investment, and has the ability to bear the economic risks of the investment in this Warrant. The Warrantholder has had an opportunity to ask questions and receive answers from the Company regarding the terms and conditions of the offering of the Warrant and the business, properties, prospects and financial condition of the Company.

     (d) Risk of No Registration. The Warrantholder understands that if the Company does not register with the SEC pursuant to Section 12 of the Securities Exchange Act of 1934 (the “1934 Act”), or file reports pursuant to Section 15(d) of the 1934 Act, or if a registration statement covering the securities under the Act is not in effect when it desires to sell (i) the rights to purchase Preferred Stock pursuant to this Agreement or (ii) the Preferred Stock issuable upon exercise of the right to purchase, it may be required to hold such securities for an indefinite period. The Warrantholder also understands that any sale of (A) its rights hereunder to purchase Preferred Stock or (B) Preferred Stock issued or issuable hereunder which might be made by it in reliance upon Rule 144 promulgated under the Act may be made only in accordance with the terms and conditions of that Rule.

     (e) Accredited Investor. Warrantholder is an “accredited investor” within the meaning of the Rule 501 of Regulation D promulgated under the Act, as presently in effect.

     (f) Authorization. The Warrantholder has full power and authority to enter into this Agreement. This Agreement constitutes a legal, valid and binding agreement of the Warrantholder, enforceable in accordance with its terms.

     (g) Agreement to Comply with the Securities Act; Legend. The Warrantholder, by acceptance of this Warrant, agrees to comply in all respects with the provisions of this Section 10(g) and the restrictive legend requirements set forth on the face of this Warrant and further agrees that such Warrantholder shall not offer, sell or otherwise dispose of this Warrant or any shares of Preferred Stock or Common Stock to be issued upon exercise hereof except under circumstances that will not result in a violation of the Act. This Warrant and all Preferred Stock and Common Stock issued upon exercise of this Warrant (unless registered under the Act) shall be stamped or imprinted with a legend in substantially the form set forth on the first page of this Agreement.

     (h) Voting Agreement. Notwithstanding anything to the contrary contained herein, if this Warrant is exercised in whole or in part during the term of the Third Amended and Restated Voting Agreement, dated as of December 30, 2011, among the Company, each holder of the Company’s preferred stock and the holders of Common Stock named therein, as amended by the First Amendment to the Third Amended and Restated Voting Agreement, dated as of January 19, 2012, among the Company, each holder of the Company’s preferred stock and the holders of Common Stock named therein (as such agreement may be amended or amended and restated from time to time, the “Voting Agreement”), the Warrantholder shall become a party to the Voting Agreement by executing an Adoption Agreement or a counterpart signature page to the Voting Agreement agreeing to be bound by and subject to the terms of the Voting Agreement and any other documents required to be executed and delivered by the Voting Agreement, all in accordance with Section 6.1 of the Voting Agreement, as such provision may be amended or amended and restated from time to time. Compliance with this Section 10(h) shall be a pre-condition to the exercise of this Warrant and the issuance by the Company of any securities hereunder.

     (i) Lock-up Agreement. On or prior to the Effective Date, the Warrantholder shall enter into a lockup agreement in favor of the underwriters in connection with the Company’s contemplated initial public offering, as described in the Company’s Registration Statement on Form S-1 (333-177172), as amended, filed with the SEC.

          SECTION 11. TRANSFERS.

     In connection with a collateral arrangement arising out of Warrantholder’s borrowing arrangements with its lenders, each taker and holder of this Agreement, by taking or holding the same, consents and agrees that this Agreement, when endorsed in blank (and subject to the other transfer requirements set forth in this Section 11), shall be deemed negotiable, and that the holder hereof, when this Agreement shall have been so endorsed and its transfer recorded on the Company’s books, shall be treated by the Company and all other persons dealing with this Agreement as the absolute owner hereof for any purpose and as the person entitled to exercise the rights represented by this Agreement. Subject to compliance with applicable federal and state securities laws, the transfer conditions referred to in the legend endorsed hereon and the transfer conditions set forth in this Section 11, this Warrant and all rights hereunder are transferable, in whole or in part, by the Warrantholder without charge to the Warrantholder, upon surrender of this Warrant to the Company at its then principal executive offices with a properly completed and duly executed notice of transfer in the form attached hereto as Exhibit III (the “Transfer Notice”), together with funds sufficient to pay any transfer taxes described in Section 9(a) in connection

with the making of such transfer. Upon such compliance, surrender and delivery and, if required, such payment, the transfer of the Warrant shall be recorded on the books of the Company and the Company shall execute and deliver a new Warrant in the name of the assignee or assignees and in the denominations specified in such Transfer Notice, and shall issue to the assignor a new Warrant evidencing the portion of this Warrant, if any, not so assigned and this Warrant shall promptly be cancelled. The Warrantholder shall not transfer the Warrant or any of the rights hereunder without the prior written approval of the Company, which approval shall not be unreasonably withheld, to any individual, person, corporation, partnership or other entity that is a direct competitor of the Company. Notwithstanding anything to the contrary contained herein, no assignee or transferee of this Warrant or any of the rights hereunder (except any Affiliate of Warrantholder) shall be entitled to the information rights set forth in Section 9(i) of this Agreement or any other non-public information relating to the Company.

          SECTION 12. MISCELLANEOUS.

     (a) Effective Date. The provisions of this Agreement shall be construed and shall be given effect in all respects as if it had been executed and delivered by the parties hereto on the date hereof. This Agreement shall be binding upon any successors and assigns of the Company and the successors and permitted assigns of the Warrantholder.

     (b) Remedies. In the event of any default hereunder, the non-defaulting party may proceed to protect and enforce its rights either by suit in equity and/or by action at law, including but not limited to an action for damages as a result of any such default, and/or an action for specific performance for any default where such party will not have an adequate remedy at law and where damages will not be readily ascertainable. Each party to this Agreement expressly agrees that it shall not oppose an application by the other party or any other person entitled to the benefit of this Agreement requiring specific performance of any or all provisions hereof or enjoining the breaching party from continuing to commit any such breach of this Agreement.

     (c) No Impairment of Rights. The Company will not, by amendment of its Charter or through any other means, avoid or seek to avoid the observance or performance of any of the terms of this Agreement, but will at all times in a commercially reasonable manner assist in the carrying out of all such terms.

     (d) Additional Documents. The Company, upon execution of this Agreement, shall provide the Warrantholder with certified resolutions relating to (i) the reservation of the Preferred Stock issuable upon exercise of the Warrantholder’s rights hereunder as of the Effective Date and (ii) the authorization of the execution and delivery by the Company of this Agreement and the performance of all obligations of the Company hereunder, including the issuance to the Warrantholder of the right to acquire the shares of Preferred Stock and the Common Stock into which it may be converted.

     (e) Attorney’s Fees. In any litigation, arbitration or court proceeding between the Company and the Warrantholder relating hereto, the prevailing party shall be entitled to attorneys’ fees and expenses and all costs of proceedings incurred in enforcing this Agreement. For the purposes of this Section 12(e), attorneys’ fees shall include without limitation fees incurred in connection with the following: (i) contempt proceedings; (ii) discovery; (iii) any motion, proceeding or other activity of any kind in connection with an insolvency proceeding; (iv) garnishment, levy, and debtor and third party examinations; and (v) post-judgment motions and proceedings of any kind, including without limitation any activity taken to collect or enforce any judgment.

     (f) Severability. In the event any one or more of the provisions of this Agreement shall for any reason be held invalid, illegal or unenforceable, the remaining provisions of this

Agreement shall be unimpaired, and the invalid, illegal or unenforceable provision shall be replaced by a mutually acceptable valid, legal and enforceable provision, which comes closest to the intention of the parties underlying the invalid, illegal or unenforceable provision.

     (g) Notices. Except as otherwise provided herein, any notice, demand, request, consent, approval, declaration, service of process or other communication that is required, contemplated, or permitted under this Agreement or with respect to the subject matter hereof shall be in writing, and shall be deemed to have been validly served, given, delivered, and received upon the earlier of: (i) the day of transmission by facsimile or hand delivery if transmission or delivery occurs on a Business Day at or before 5:00 pm in the time zone of the recipient, or, if transmission or delivery occurs on a non-Business Day or after such time, the first Business Day thereafter, or the first Business Day after deposit with an overnight express service or overnight mail delivery service; or (ii) the third calendar day after deposit in the United States mails, with proper first class postage prepaid, and shall be addressed to the party to be notified as follows:

or to such other address as each party may designate for itself by like notice.

     (h) Entire Agreement; Amendments. This Agreement constitute the entire agreement and understanding of the parties hereto in respect of the subject matter hereof, and supersede and replace in their entirety any prior proposals, term sheets, letters, negotiations or other documents or agreements, whether written or oral, with respect to the subject matter hereof (including Lender’s revised proposal letter dated March 16, 2012). None of the terms of this Agreement may be amended except by an instrument executed by each of the parties hereto.

     (i) Headings. The various headings in this Agreement are inserted for convenience only and shall not affect the meaning or interpretation of this Agreement or any provisions hereof.

     (j) Advice of Counsel. Each of the parties represents to each other party hereto that it has discussed (or had an opportunity to discuss) with its counsel this Agreement and, specifically, the provisions of Sections 12(m), 12(n), 12(o), 12(p) and 12(r).

     (k) No Strict Construction. The parties hereto have participated jointly in the negotiation and drafting of this Agreement. In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties hereto and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provisions of this Agreement.

     (l) No Waiver. No omission or delay by a party to this Agreement at any time to enforce any right or remedy reserved to it, or to require performance of any of the terms, covenants or provisions hereof by the other party to this Agreement at any time designated, shall be a waiver of any such right or remedy, nor shall it in any way affect the right of such party to enforce such provisions thereafter.

     (m) Survival. Except as otherwise provided herein, all agreements set forth in Sections 10(g), 10(h) and 12(r) hereof and all representations and warranties contained in this Agreement shall survive the execution and delivery of this Agreement and the expiration or other termination of this Agreement.

     (n) Governing Law. This Agreement has been negotiated and delivered to Warrantholder in the State of California, and shall have been accepted by Warrantholder in the State of California. Delivery of Preferred Stock to Warrantholder by the Company under this Agreement is due in the State of California. This Agreement shall be governed by, and construed and enforced in accordance with, the laws of the State of California, excluding conflict of laws principles that would cause the application of laws of any other jurisdiction.

     (o) Consent to Jurisdiction and Venue. All judicial proceedings arising in or under or related to this Agreement may be brought in any state or federal court located in the State of California. By execution and delivery of this Agreement, each party hereto generally and unconditionally: (i) consents to nonexclusive personal jurisdiction in Santa Clara County, State of California; (ii) waives any objection as to jurisdiction or venue in Santa Clara County, State of California; and (iii) agrees not to assert any defense based on lack of jurisdiction or venue in the aforesaid courts. Service of process on any party hereto in any action arising out of or relating to this Agreement shall be effective if given in accordance with the requirements for notice set forth in Section 12(g), and shall be deemed effective and received as set forth in Section 12(g). Nothing herein shall affect the right to serve process in any other manner permitted by law or shall limit the right of either party to bring proceedings in the courts of any other jurisdiction.

     (p) Mutual Waiver of Jury Trial/Judicial Reference.

          (i) Because disputes arising in connection with complex financial transactions are most quickly and economically resolved by an experienced and expert person and the parties wish applicable state and federal laws to apply (rather than arbitration rules), the parties desire that their disputes be resolved by a judge applying such applicable laws. EACH OF THE COMPANY AND WARRANTHOLDER SPECIFICALLY WAIVE ANY RIGHT IT MAY HAVE TO TRIAL BY JURY OF ANY CAUSE OF ACTION, CLAIM, CROSS-CLAIM, COUNTERCLAIM, THIRD PARTY CLAIM OR ANY OTHER CLAIM (COLLECTIVELY, “CLAIMS”) ASSERTED BY THE COMPANY AGAINST WARRANTHOLDER OR ITS ASSIGNEE OR BY WARRANTHOLDER OR ITS ASSIGNEE AGAINST THE COMPANY. This waiver extends to all such Claims, including Claims that involve Persons other than the Company and Warrantholder; Claims that arise out of or are in any way connected to the relationship between the Company and Warrantholder; and any Claims for damages, breach of contract, specific performance, or any equitable or legal relief of any kind, arising out of this Agreement.

          (ii) If the waiver of jury trial set forth in Section 12(p)(i) is ineffective or unenforceable, the parties agree that all Claims shall be resolved by reference to a private judge sitting without a jury, pursuant to Code of Civil Procedure Section 638, before a mutually acceptable referee or, if the parties cannot agree, a referee selected by the Presiding Judge of the Santa Clara County, California. Such proceeding shall be conducted in Santa Clara County, California, with California rules of evidence and discovery applicable to such proceeding.

          (iii) In the event Claims are to be resolved by judicial reference, either party may seek from a court identified in Section 12(o), any prejudgment order, writ or other relief and have such prejudgment order, writ or other relief enforced to the fullest extent permitted by law notwithstanding that all Claims are otherwise subject to resolution by judicial reference.

     (q) Counterparts. This Agreement and any amendments, waivers, consents or supplements hereto may be executed in any number of counterparts, and by different parties hereto in separate counterparts, each of which when so delivered shall be deemed an original, but all of which counterparts shall constitute but one and the same instrument.

     (r) Specific Performance. The parties hereto hereby declare that it is impossible to measure in money the damages which will accrue to Warrantholder by reason of the Company’s failure to perform any of the obligations under this Agreement and agree that the terms of this Agreement shall be specifically enforceable by Warrrantholder. If Warrantholder institutes any action or proceeding to specifically enforce the provisions hereof, any person against whom such action or proceeding is brought hereby waives the claim or defense therein that Warrantholder has an adequate remedy at law, and such person shall not offer in any such action or proceeding the claim or defense that such remedy at law exists.
