LOAN AND SECURITY AGREEMENT

          The Borrower and Lender identified on the cover page of this document have entered or anticipate entering into one or more transactions pursuant to which Lender agrees to make available to Borrower a loan facility governed by the terms and conditions set forth in this document and one or more Supplements executed by Borrower and Lender which incorporate this document by reference. Each Supplement constitutes a supplement to and forms part of this document, and. will be read and construed as one with this document, so that this document and the Supplement constitute a single agreement between the parties (collectively referred to as this “Agreement”).

          Accordingly, the parties agree as follows:

ARTICLE 1 — INTERPRETATION

     1.1 Definitions. The terms defined in Article 10 and in the Supplement will have the meanings therein specified for purposes of this Agreement.

     1.2 Inconsistency. In the event of any inconsistency between the provisions of any Supplement and this document, the provisions of the Supplement will be controlling for the purpose of all relevant transactions.

ARTICLE 2 — THE COMMITMENT AND LOANS

     2.1 The Commitment. Subject to the terms and conditions of this Agreement, Lender agrees to make term loans to Borrower from time to time from the Closing Date and to, but not including, the Termination Date in an aggregate principal amount not exceeding the Commitment. The Commitment is not a revolving credit commitment, and any repayments made hereunder shall not be reborrowed. Each Loan requested by Borrower to be made on a single Business Day shall be for a minimum principal amount set forth in the Supplement, except to the extent the remaining Commitment is a lesser amount

     2.2 Notes Evidencing Loans; Repayment. Each Loan shall be evidenced by a separate Note payable to the order of Lender, in the total principal amount of the Loan. Principal and interest of each Loan shall be payable at the times set forth in the Note and regularly scheduled payments thereof and each Final Payment shall be effected by automatic debit of the appropriate funds from Borrower’s Primary Operating Account as specified in the Supplement hereto.

     2.3 Procedures for Borrowing.

     (a) At least five (5) Business Days’ prior to a proposed Borrowing Date, Lender shall have received from Borrower a written request for a borrowing hereunder (a “Borrowing Request”). Each Borrowing Request shall be in substantially the form of Exhibit “B” to the Supplement, shall be executed by a responsible executive or financial officer of Borrower, and shall state how much is requested, and shall be accompanied by such other information and documentation as Lender may reasonably request

     (b) No later than 1:00 p.m. Pacific Standard Time on the Borrowing Date, if Borrower has satisfied the conditions precedent in Article 4, Lender shall make the Loan available to Borrower in immediately available funds. Borrower shall deliver to Lender an original executed Note(s) for the Loan(s) covered by the Borrowing Request pursuant to Section 4.2(d).

     2.4 Interest. Except as otherwise specified in the applicable Note and/or Supplement, Basic Interest on the outstanding principal balance of each Loan shall accrue daily at the Designated Rate from the Borrowing Date. If the outstanding principal balance of such Loan is not paid at maturity, interest shall accrue at the Default Rate until paid in full, as further set forth herein.

     2.5 Final Payment. Borrower shall pay the Final Payment, if any, with respect to each Loan on the date set forth in the Note evidencing such Loan.

     2.6 Interest Rate Calculation. Basic Interest, along with charges and fees under this Agreement and any Loan Document, shall be calculated for actual days elapsed on the basis of a 360-day year, which results in higher interest, charge or fee payments than if a 365-day year were used. In no event shall Borrower be obligated to pay Lender interest, charges or fees at a rate in excess of the highest rate permitted by applicable law from time to time in effect.

     2.7 Default Interest. Any unpaid payments of principal or interest or the Final Payment with respect to any Loan shall bear interest from their respective maturities, whether scheduled or accelerated, at the

Designated Rate for such Loan plus five percent (5.00%) per annum, until paid in full, whether before or after judgment (the “Default Rate”). Borrower shall pay such interest on demand.

     2.8 Late Charges. If Borrower is late in making any payment of principal or interest or Final Payment under this Agreement by more than five (5) days, Borrower agrees to pay a late charge of five percent (5%) of the installment due, but not less than fifty dollars ($50.00) for any one such delinquent payment; provided, however, that Borrower shall not pay such late charge if the failure to make any such payment when due (taking into account applicable grace periods) arises solely from either (i) Lender’s failure to effect timely automatic debits of the appropriate funds from Borrower’s Primary Operating Account as provided in Section 2.2 hereunder or (ii) a technical malfunction of an ACH transfer (and not for any other reason, including, without limitation, insufficient funds or an act, or failure to act, by Borrower, which adversely affects the ACH transfer). This late charge may be charged by Lender for the purpose of defraying the expenses incidental to the handling of such delinquent amounts. Borrower acknowledges that such late charge represents a reasonable sum considering all of the circumstances existing on the date of this Agreement and represents a fair and reasonable estimate of the costs that will be sustained by Lender due to the failure of Borrower to make timely payments. Borrower further agrees that proof of actual damages would be costly and inconvenient. Such late charge shall be paid without prejudice to the right of Lender to collect any other amounts provided to be paid or to declare a default under this Agreement or any of the other Loan Documents or from exercising any other rights and remedies of Lender.

     2.9 Lender’s Records. Principal, Basic Interest, Final Payments and all other sums owed under any Loan Document shall be evidenced by entries in records maintained by Lender for such purpose. Each payment on and any other credits with respect to principal, Basic Interest, Final Payments and all other sums outstanding under any Loan Document shall be evidenced by entries in such records. Absent manifest error, Lender’s records shall be conclusive evidence thereof.

     2.10 Grant of Security Interests; Filing of Financing Statements.

          (a) To secure the timely payment and performance of all of Borrower’s Obligations to Lender, Borrower hereby grants to Lender continuing security interests in all of the Collateral. In connection with the foregoing, Borrower authorizes Lender to prepare and file any financing statements describing the Collateral without otherwise obtaining Borrower’s signature or consent with respect to the filing of such financing statements.

          (b) In furtherance of Borrower’s grant of the security interests in the Collateral pursuant to Section 2.10(a) above, Borrower hereby pledges and grants to the Lender a security interest in all the Shares, together with all proceeds and substitutions thereof, all cash, stock and other moneys and property paid thereon, all rights to subscribe for securities declared or granted in connection therewith, and all other cash and non-cash proceeds of the foregoing, as security for the performance of the Obligations. To the extent required by the terms and conditions governing the Shares, Borrower shall cause the books of each entity whose Shares are part of the Collateral and any transfer agent to reflect the pledge of the Shares. Upon the occurrence and during the continuance of an Event of Default hereunder, Lender may effect the transfer of any securities included in the Collateral (including but not limited to the Shares) into the name of Lender and cause new certificates representing such securities to be issued in the name of Lender or its transferee(s). Borrower will execute and deliver such documents, and take or cause to be taken such actions, as Lender may reasonably request to perfect or continue the perfection of Lender’s security interest in the Shares. Unless an Event of Default shall have occurred and be continuing, Borrower shall be entitled to exercise any voting rights with respect to the Shares and to give consents, waivers and ratifications in respect thereof, provided that no vote shall be cast or consent, waiver or ratification given or action taken which would be inconsistent with any of the terms of this Agreement or which would constitute or create any violation of any of such terms. All such rights to vote and give consents, waivers and ratifications shall terminate upon the occurrence and continuance of an Event of Default.

          (c) Borrower is and shall remain absolutely and unconditionally liable for the performance of its obligations under the Loan Documents, including, without limitation, any deficiency by reason of the failure of the Collateral to satisfy all amounts due Lender under any of the Loan Documents.

          (d) All Collateral pledged by Borrower under this Agreement and any Supplement shall secure the timely payment and performance of all Obligations under this Agreement, the Notes and the other Loan

Documents. Except as expressly provided in this Agreement, no Collateral pledged under this Agreement or any Supplement shall be released until such time as all Obligations (other than contingent, reimbursement and indemnification obligations for which no claim has been made) under this Agreement and the other Loan Documents have been satisfied and paid in full.

ARTICLE 3 — REPRESENTATIONS AND WARRANTIES

     3.1 Due Organization. Borrower is a corporation duly organized and validly existing in good standing under the laws of the jurisdiction of its incorporation, and is duly qualified to conduct business and is in good standing in each other jurisdiction in which its business is conducted or its properties are located, except where the failure to be so qualified would not reasonably be expected to have a Material Adverse Effect.

     3.2 Authorization, Validity and Enforceability. The execution, delivery and performance of all Loan Documents executed by Borrower are within Borrower’s powers, have been duly authorized, and are not in conflict with Borrower’s certificate of incorporation or by-laws, or the terms of any charter or other organizational document of Borrower, as amended from time to time; and all such Loan Documents constitute valid and binding obligations of Borrower, enforceable in accordance with their terms (except as may be limited by bankruptcy, insolvency and similar laws affecting the enforcement of creditors’ rights in general, and subject to general principles of equity).

     3.3 Compliance with Applicable Laws. Borrower has complied with all licensing, permit and/or other requirements necessary to lawfully conduct the business in which it is engaged, and to any sales, leases or the furnishing of services by Borrower, including without limitation those requiring consumer or other disclosures, the noncompliance with which would have a Material Adverse Effect.

     3.4 No Conflict. The execution, delivery, and performance by Borrower of all Loan Documents are not in conflict with any law, rule, regulation, order or directive, or any indenture, agreement, or undertaking to which Borrower is a party or by which Borrower may be bound or affected, except to the extent any such conflict does not cause a Material Adverse Effect. Without limiting the generality of the foregoing, the issuance to Lender (or its designee) of shares of Borrower’s Series D Preferred Stock and the grant of registration rights in connection therewith do not violate any agreement or instrument by which Borrower is bound or require the consent of any holders of Borrower’s securities other than consents which have been obtained prior to the Closing Date.

     3.5 No Litigation, Claims or Proceedings. There is no material litigation, tax claim, proceeding or dispute pending, or, to the knowledge of Borrower, threatened against or affecting Borrower, its property or the conduct of its business.

     3.7 No Subsidiaries. Borrower is not a majority owner of or in a control relationship with any other business entity.

     3.8 Environmental Matters. To its knowledge after reasonable inquiry, Borrower has concluded that Borrower is in compliance with Environmental Laws, except to the extent a failure to be in such compliance could not reasonably be expected to have a Material Adverse Effect.

     3.9 No Event of Default. No Default or Event of Default has occurred and is continuing.

     3.10 Full Disclosure. None of the representations or warranties made by Borrower in the Loan Documents as of the date such representations and warranties are made or deemed made, and none of the statements contained in any exhibit, report, statement or certificate furnished by or on behalf of Borrower in connection with the Loan Documents (including disclosure materials delivered by or on behalf of Borrower to Lender prior to the Closing Date or pursuant to Section 5.2 hereof), contains any untrue statement of a material fact or omits any material fact required to be stated therein or necessary to make the statements made therein, in light of the circumstances under which they are made, not misleading as of the time when made or delivered.

Except for the security interests created by this Agreement and Permitted Liens, (i) Borrower is and will be the unconditional legal and beneficial owner of the Collateral, and (ii) the Collateral is genuine and subject to no Liens, rights or defenses of others. There exist no prior assignments or encumbrances of record with the U.S. Patent and Trademark Office or U.S. Copyright Office affecting any Collateral in favor of any third party other than Lender.

     (b) Rights to Payment. The names of the obligors, amount owing to Borrower, due dates and all other information with, respect to the Rights to Payment are and will be correctly stated in all material respects in all Records relating to the Rights to Payment.

     (c) No claim or litigation regarding any of the foregoing is pending or, to Borrower’s knowledge, threatened, which, in either case, could reasonably be expected to have a Material Adverse Effect.

     3.13 Regulatory Compliance. Borrower has met the minimum funding requirements of ERISA with respect to any employee benefit plans subject to ERISA. No event has occurred resulting from Borrower’s failure to comply with ERISA that is reasonably likely to result in Borrower’s incurring any liability that could have a Material Adverse Effect. Borrower is not an “investment company” or a company “controlled” by an “investment company” within the meaning of the Investment Company Act of 1940.

     6.2 Liens. Create, incur, assume or permit to exist any Lien, or grant any other Person a negative pledge, on any of Borrower’s property, except Permitted Liens. Borrower and Lender agree that this covenant is not intended to constitute a lien, deed of trust, equitable mortgage, or security interest of any kind on any of Borrower’s real property, and this Agreement shall not be recorded or recordable. Notwithstanding the foregoing, however, violation of this covenant by Borrower shall constitute an Event of Default

     6.3 Dividends. Except after a Qualified Public Offering, pay any dividends or purchase, redeem or otherwise acquire or make any other distribution with respect to any of Borrower’s capital stock, except (a) dividends or other distributions solely of capital stock of Borrower, and (b) so long as no Event of Default has occurred and is continuing and the same would be permitted under applicable law, repurchases of stock from employees upon termination of employment under reverse vesting or similar repurchase plans not to exceed $200,000 in any calendar year.

In determining whether the proposed merger, consolidation or asset sale would result in an increased credit risk, Lender may consider, among other things, changes in Borrower’s management team, employee base, access to equity markets, venture capital support, financial position and/or disposition of intellectual property rights which may reasonably be anticipated as a result of the transaction.

     6.5 Sales of Assets. Sell, transfer, lease, license or otherwise dispose of (a “Transfer”) any of Borrower’s assets except (i) non-exclusive licenses of Intellectual Property in the ordinary course of business consistent with industry practice; (ii) exclusive licenses of Intellectual Property in the ordinary course of business consistent with industry practice and approved by Borrower’s Board of Directors; provided that such exclusive licenses neither result in a legal transfer of title of the licensed Intellectual Property nor have the same effect as a sale of such Intellectual Property; (iii) Transfers of worn-out, obsolete or surplus property (each as determined by Borrower in its reasonable judgment); (iv) Transfers of Inventory; (v) Transfers constituting Permitted Liens; (vi) Transfers permitted in Section 6.6 hereunder; and (vii) Transfers of Collateral (other than Intellectual Property) for fair consideration and in the ordinary course of its business.

     (f) Loans to officers and directors of Borrower not involving the actual advance of cash by Borrower solely to finance the purchases by such officers or directors of shares of capital stock of Borrower on terms approved by Borrower’s board of directors, including a majority of non-interested directors.

     6.7 Transactions With Related Persons. Directly or indirectly enter into any transaction with or for the benefit of a Related Person on terms more favorable to the Related Person than would have been obtainable in an “arms’ length” dealing, unless such transaction has been approved by Borrower’s board of directors, including a majority of non-interested directors.

     6.8 Other Business. Engage in any material line of business other than the business Borrower conducts as of the Closing Date or any other businesses reasonably related thereto.

     6.9 Financing Statements and Other Actions. Fail to execute and deliver to Lender all financing statements, notices and other documents (including, without limitation, any filings with the United States Patent and Trademark Office) from time to time reasonably requested by Lender to maintain a first perfected security interest in the Collateral in favor of Lender; perform such other acts, and execute and deliver to Lender such additional conveyances, assignments, agreements and instruments, as Lender may at any time request in connection with the administration and enforcement of this Agreement or Lender’s rights, powers and remedies hereunder.

     6.10 Compliance. Become an “investment company” or controlled by an “investment company,” within the meaning of the Investment Company Act of 1940, or become principally engaged in, or undertake as one of its important activities, the business of extending credit for the purpose of purchasing or carrying margin stock, or use the proceeds of any Loan for such purpose. Fail to meet the minimum funding requirements of ERISA, permit a Reportable Event or Prohibited Transaction, as defined in ERISA to occur, fail to comply with the Federal Fair Labor Standards Act or violate any law or regulation, which violation could have a Material Adverse Effect or a material adverse effect on the Collateral or the priority of Lender’s Lien on the Collateral, or permit any of its subsidiaries to do any of the foregoing.

     6.11 Other Deposit and Securities Accounts. Maintain any deposit accounts or accounts holding securities owned by Borrower except (i) Deposit Accounts and investment/securities accounts as set forth in the Supplement, and (ii) other Deposit Accounts and securities/investment accounts, in each case, with respect to which Borrower and Lender shall have taken such action as Lender reasonably deems necessary to obtain a perfected first security interest therein.

(100%) of the cost of such property; and (b) issue any additional Shares.

     6.13 Prepayment of Indebtedness. Prepay, redeem or otherwise satisfy in any manner prior to the scheduled repayment thereof any Indebtedness (other than the Loans). Notwithstanding the foregoing, Lender agrees that the conversion or exchange into Borrower’s equity securities of any Indebtedness (other than the Loans) shall not be prohibited by this Section 6.13.

ARTICLE 7 — EVENTS OF DEFAULT

     7.1 Events of Default; Acceleration. Upon the occurrence and during the continuation of any Default, the obligation of Lender to make any additional Loan shall be suspended. The occurrence of any of the following (each, an “Event of Default”) shall terminate any obligation of Lender to make any additional Loan; and shall, at the option of Lender (1) make all sums of Basic Interest and principal, all Final Payments, and any Obligations and other amounts owing under any Loan Documents immediately due and payable without notice of default, presentment or demand for payment, protest or notice of nonpayment or dishonor or any other notices or demands, and (2) give Lender the right to exercise any other right or remedy provided by contract or applicable law:

     (a) Borrower shall fail to pay any principal, interest or Final Payment under this Agreement or any Note, or fail to pay any fees or other charges when due under any Loan Document, and such failure continues for three (3) Business Days or more after the same first becomes due (each, individually, a “Payment Default”); or an Event of Default as defined in any other Loan Document shall have occurred. Notwithstanding the foregoing, in the event of a Payment Default resulting solely from the technical malfunction of an ACH transfer (and not for any other reason, including, without limitation, insufficient funds or an act, or failure to act, by Borrower, which adversely affects the ACH transfer) then Lender shall provide Borrower notice of the same and Borrower shall have 5 days from the receipt of such notice to cure the Payment Default.

     (b) Any representation or warranty made, or financial statement, certificate or other document provided, by Borrower under any Loan Document shall prove to have been false or misleading in any material respect when made or deemed made herein.

     (c) (i)Borrower shall fail to pay its debts generally as they become due or (ii) shall commence any Insolvency Proceeding with respect to itself; an involuntary Insolvency Proceeding shall be filed against Borrower, or a custodian, receiver, trustee, assignee for the benefit of creditors, or other similar official, shall be appointed to take possession, custody or control of the properties of Borrower, and such involuntary Insolvency Proceeding, petition or appointment is acquiesced to by Borrower or is not dismissed within forty five (45) days; or the dissolution or termination of the business of Borrower; or Borrower shall take any corporate action for the purpose of effecting, approving, or consenting to any of the foregoing.

     (d) Borrower shall be in default beyond any applicable period of grace or cure under any other agreement involving the borrowing of money, the purchase of property, the advance of credit or any other monetary liability of any kind to Lender or to any Person which results in the acceleration of payment of such obligation in an amount in excess of the Threshold Amount.

     (e) Any governmental or regulatory authority shall take any judicial or administrative action, or any defined benefit pension plan maintained by Borrower shall have any unfunded liabilities, any of which, would have a Material Adverse Effect.

     (f) Except as set forth in Section 6.4, any sale, transfer or other disposition of all or a substantial or material part of the assets of Borrower, including without limitation to any trust or similar entity, shall occur.

     (g) Any judgment(s) singly or in the aggregate in excess of the Threshold Amount shall be entered against Borrower which remain unsatisfied, unvacated or unstayed pending appeal for ten (10) or more days after entry thereof.

     (h) At any time prior to the initial sale of Borrower’s equity securities to the public pursuant to a registration statement filed under the Securities Act of 1933, as amended, any Person or two or more Persons (other than any “Excluded Person” as defined below) acting in concert shall have acquired (in a single transaction or series of related transactions) beneficial ownership (within the meaning of Rule 13d-3 of the Securities and Exchange Commission) of outstanding shares of voting stock of Borrower representing fifty percent (50%) or more of the voting power of all shares of Borrower’s voting stock that are outstanding

immediately after such acquisition. As used in this paragraph, “Excluded Person” means: (i) any Person who is a stockholder of Borrower as of the Closing Date; (ii) a venture capital firm or similar investment fund or institution; or (iii) an affiliate of any Person described in clause (i) or (ii).

     (i) Borrower shall fail to perform or observe any covenant contained in Sections 6.1, 6.2, 6.3, 6.4, 6.5, 6.6, 6.7, 6.8, 6.10, 6.12 or 6.13 of this Agreement.

     (j) Borrower shall fail to perform or observe any covenant contained in Sections 6.9 or 6.11 of this Agreement and, if capable of being cured, the breach of such covenant is not cured within 10 Business Days after the sooner to occur of Borrower’s receipt of notice of such breach from Lender or the date on which such breach first becomes known to Borrower’s Chief Executive Officer or Chief Financial Officer.

     (k) Borrower shall fail to perform or observe any covenant contained in Article 5 or elsewhere in this Agreement or any other Loan Document (other than a covenant which is dealt with specifically elsewhere in this Article 7) and, if capable of being cured, the breach of such covenant is not cured within thirty (30) days after the sooner to occur of Borrower’s receipt of notice of such breach from Lender or the date on which such breach first becomes known to Borrower’s Chief Executive Officer or Chief Financial Officer; provided, however that if such breach is not capable of being cured within such thirty (30) day period and Borrower timely notifies Lender of such fact and Borrower diligently pursues such cure, then the cure period shall be extended to the date requested in Borrower’s notice but in no event more than ninety (90) days from the initial breach; provided, further, that such additional sixty (60) day opportunity to cure shall not apply in the case of any failure to perform or observe any covenant which has been the subject of a prior failure within the preceding one hundred eighty (180) days or which is a willful and knowing breach by Borrower.

     7.2 Remedies Upon Default. Subject to Section 6 of Part 2 of the Supplement, upon the occurrence and during the continuance of an Event of Default, Lender shall be entitled to, at its option, exercise any or all of the rights and remedies available to a secured party under the UCC or any other applicable law, and exercise any or all of its rights and remedies provided for in this Agreement and in any other Loan Document. The obligations of Borrower under this Agreement shall continue to be effective or be reinstated, as the case may be, if at any time any payment of any Obligations is rescinded or must otherwise be returned by Lender upon, on account of, or in connection with, the insolvency, bankruptcy or reorganization of Borrower or otherwise, all as though such payment had not been made.

     7.3 Sale of Collateral. Subject to Section 6 of Part 2 of the Supplement, upon the occurrence and during the continuance of an Event of Default, Lender may sell all or any part of the Collateral, at public or private sales, to itself, a wholesaler, retailer or investor, for cash, upon credit or for future delivery, and at such price or prices as Lender may deem commercially reasonable. To the extent permitted by law, Borrower hereby specifically waives all rights of redemption and any rights of stay or appraisal which it has or may have under any applicable law in effect from time to time. Any such public or private sales shall be held at such times and at such place(s) as Lender may determine. In case of the sale of all or any part of the Collateral on credit or for future delivery, the Collateral so sold may be retained by Lender until the selling price is paid by the purchaser, but Lender shall not incur any liability in case of the failure of such purchaser to pay for the Collateral and, in case of any such failure, such Collateral may be resold. Lender may, instead of exercising its power of sale, proceed to enforce its security interest in the Collateral by seeking a judgment or decree of a court of competent jurisdiction. Without limiting the generality of the foregoing, if an Event of Default is in effect,

     (1) Subject to the rights of any third parties, Lender may license, or sublicense, whether general, special or otherwise, and whether on an exclusive or non-exclusive basis, any Copyrights, Patents or Trademarks included in the Collateral throughout the world for such term or terms, on such conditions and in such manner as Lender shall in its sole discretion determine;

     (2) Lender may (without assuming any obligations or liability thereunder), at any time and from time to time, enforce (and shall have the exclusive right to enforce) against any licensee or sublicensee all rights and remedies of Borrower in, to and under any Copyright Licenses, Patent Licenses or Trademark Licenses and take or refrain from taking any action under any thereof, and Borrower hereby releases Lender from, and agrees to hold Lender free and harmless from and against any claims arising out of, any lawful action so taken or omitted to be taken with respect thereto other than claims arising out of Lender’s gross negligence or willful misconduct; and

     (3) Upon request by Lender, Borrower will execute and deliver to Lender a power of attorney, in form and substance reasonably satisfactory to Lender for the implementation of any lease, assignment, license, sublicense, grant of option, sale or other disposition of a Copyright, Patent or Trademark. In the event of any such disposition pursuant to this clause 3, Borrower shall supply its know-how and expertise relating to the products or services made or rendered in connection with Patents, the manufacture and sale of the products bearing Trademarks, and its customer lists and other records relating to such Copyrights, Patents or Trademarks and to the distribution of said products, to Lender.

     (4) If, at any time when Lender shall determine to exercise its right to sell the whole or any part of the Shares hereunder, such Shares or the part thereof to be sold shall not, for any reason whatsoever, be effectively registered under the Securities Act (or any similar statute), then Lender may, in its discretion (subject only to applicable requirements of law), sell such Shares or part thereof by private sale in such manner and under such circumstances as Lender may deem necessary or advisable, but subject to the other requirements of this Article 7, and shall not be required to effect such registration or to cause the same to be effected. Without limiting the generality of the foregoing, in any such event, Lender in its discretion may (i) in accordance with applicable securities laws proceed to make such private sale notwithstanding that a registration statement for the purpose of registering such Shares or part thereof could be or shall have been filed under the Securities Act (or similar statute), (ii) approach and negotiate with a single possible purchaser to effect such sale, and (iii) restrict such sale to a purchaser who is an accredited investor under the Securities Act and who will represent and agree that such purchaser is purchasing for its own account, for investment and not with a view to the distribution or sale of such Shares or any part thereof. In addition to a private sale as provided above in this Article 7, if any of the Shares shall not be freely distributable to the public without registration under the Securities Act (or similar statute) at the time of any proposed sale pursuant to this Article 7, then Lender shall not be required to effect such registration or cause the same to be effected but, in its discretion (subject only to applicable requirements of law), may require that any sale hereunder (including a sale at auction) be conducted subject to restrictions:

(A) as to the financial sophistication and ability of any Person permitted to bid or purchase at any such sale;

(B) as to the content of legends to be placed upon any certificates representing the Shares sold in such sale, including restrictions on future transfer thereof;

(C) as to the representations required to be made by each Person bidding or purchasing at such sale relating to such Person’s access to financial information about Borrower or any of its Subsidiaries and such Person’s intentions as to the holding of the Shares so sold for investment for its own account and not with a view to the distribution thereof; and

(D) as to such other matters as Lender may, in its discretion, deem necessary or appropriate in order that such sale (notwithstanding any failure so to register) may be effected in compliance with the Bankruptcy Code and other laws affecting the enforcement of creditors’ rights and the Securities Act and all applicable state securities laws.

     (5) Borrower recognizes that Lender may be unable to effect a public sale of any or all the Shares and may be compelled to resort to one or more private sales thereof in accordance with clause (4) above. Borrower also acknowledges that any such private sale may result in prices and other terms less favorable to the seller than if such sale were a public sale and, notwithstanding such circumstances, agrees that any such private sale shall not be deemed to have been made in a commercially unreasonable manner solely by virtue of such sale being private. Lender shall be under no obligation to delay a sale of any of the Shares for the period of time necessary to permit the applicable Subsidiary to register such securities for public sale under the Securities Act, or under applicable state securities laws, even if Borrower and/or the Subsidiary would agree to do so.

     7.4 Borrower’s Obligations Upon Default. Upon the request of Lender after the occurrence and during the continuance of an Event of Default, Borrower will:

     (a) Assemble and make available to Lender the Collateral at such place(s) as Lender shall reasonably designate, segregating all Collateral so that each item is capable of identification; and

     (b) Subject to the rights of any lessor, permit Lender, by Lender’s officers, employees, agents and representatives, to enter any premises where any Collateral is located, to take possession of the Collateral, to complete the processing, manufacture or repair of any Collateral, and to remove the Collateral, or to conduct any public or private sale of the Collateral, all without any liability of Lender for rent or other compensation for the use of Borrower’s premises-

ARTICLE 8 — SPECIAL COLLATERAL PROVISIONS

     8.1 Compromise and Collection. Borrower and Lender recognize that setoffs, counterclaims, defenses and other claims may be asserted by obligors with respect to certain of the Rights to Payment; that certain of the Rights to Payment may be or become uncollectible in whole or in part; and that the expense and probability of success of litigating a disputed Right to Payment may exceed the amount that reasonably may be expected to be recovered with respect to such Right to Payment. Borrower hereby authorizes Lender, after and during the continuance of an Event of Default, to compromise with the obligor, accept in full payment of any Right to Payment such amount as Lender shall negotiate with the obligor, or abandon any Right to Payment. Any such action by Lender shall be considered commercially reasonable so long as Lender acts in good faith based on information known to it at the time it takes any such action.

     8.2 Performance of Borrower’s Obligations.

Without having any obligation to do so, upon reasonable prior notice to Borrower, Lender may perform or pay any obligation which Borrower has agreed to perform or pay under this Agreement, including, without limitation, the payment or discharge of taxes or Liens levied or placed on or threatened against the Collateral. In so performing or paying, Lender shall in good faith determine the reasonable action to be- taken and the amount necessary to discharge such obligations. Borrower shall reimburse Lender on demand for any amounts paid by Lender pursuant to this Section, which amounts shall constitute Obligations secured by the Collateral and shall bear interest from the date of demand at the Default Rate.

8.3 Power of Attorney. For the purpose of protecting and preserving the Collateral and Lender’s rights under this Agreement, Borrower hereby irrevocably appoints Lender, with full power of substitution, as its attorney-in-fact with full power and authority, after the occurrence and during the continuance of an Event of Default, to do any act which Borrower is obligated to do hereunder, to exercise such rights with respect to the Collateral as Borrower might exercise; to use such Inventory, Equipment, Fixtures or other property as Borrower might use; to enter Borrower’s premises; to give notice of Lender’s security interest in, and to collect the Collateral; and before or after Default, to execute and file in Borrower’s name any financing statements, amendments and continuation statements, account control agreements or other Security Documents necessary or desirable to perfect or continue the perfection of Lender’s security interests in the Collateral. Borrower hereby ratifies all that Lender shall lawfully do or cause to be done by virtue of this appointment.

     8.4 Authorization for Lender to Take Certain Action. The power of attorney created in Section 8.3 is a power coupled with an interest and shall be irrevocable. The powers conferred on Lender hereunder are solely to protect its interests in the Collateral and shall not impose any duty upon Lender to exercise such powers. In no event shall Lender or any of its directors, officers, employees, agents or representatives be responsible to Borrower for any act or failure to act, except for gross negligence or willful misconduct. After the occurrence and during the continuance of an Event of Default, Lender may exercise this power of attorney without notice to or assent of Borrower, in the name of Borrower, or in Lender’s own name, from time to time in Lender’s reasonable discretion and at Borrower’s expense. To further carry out the terms of this Agreement, after the occurrence and during the continuance of an Event of Default, Lender may:

     (a) Execute any statements or documents or take possession of, and endorse and collect and receive delivery or payment of, any checks, drafts, notes, acceptances or other instruments and documents constituting Collateral, or constituting the payment of amounts due and to become due or any performance to be rendered with respect to the Collateral.

     (b) Sign and endorse any invoices, freight or express bills, bills of lading, storage or warehouse receipts; drafts, certificates and statements under any commercial or standby letter of credit relating to Collateral; assignments, verifications and notices in connection with Accounts; or any other documents relating to the Collateral, including without limitation the Records.

     (c) Use or operate Collateral or any other property of Borrower for the purpose of preserving or liquidating Collateral.

     (d) File any claim or take any other action or proceeding in any court of law or equity or as otherwise deemed appropriate by Lender for the purpose of collecting any and all monies due or securing any performance to be rendered with respect to the Collateral.

      (e) Commence, prosecute or defend any suits, actions or proceedings or as otherwise deemed appropriate by Lender for the purpose of protecting or collecting the Collateral. In furtherance of this right, upon the occurrence and during the continuance of an Event of Default, Lender may apply for the appointment of a receiver or similar official to operate Borrower’s business.

     (f) Prepare, adjust, execute, deliver and receive payment under insurance claims, and collect and receive payment of and endorse any instrument in payment of loss or returned premiums or any other insurance refund or return, and apply such amounts at Lender’s sole discretion, toward repayment of the Obligations or replacement of the Collateral.

     8.5 Application of Proceeds. Any Proceeds and other monies or property received by Lender pursuant to the terms of this Agreement or any Loan Document may be applied by Lender first to the payment of expenses of collection, including without limitation reasonable attorneys’ fees, and then to the payment of the Obligations in such order of application as Lender may elect.

     8.6 Deficiency. If the Proceeds of any disposition of the Collateral are insufficient to cover all costs and expenses of such sale and the payment in full of all the Obligations, plus all other sums required to be expended or distributed by Lender, then Borrower shall be liable for any such deficiency.

     8.7 Lender Transfer. Upon a transfer of all or any part of the Obligations permitted under this Agreement, Lender may transfer all or part of the Collateral and shall be fully discharged thereafter from all liability and responsibility with respect to such Collateral so transferred, and the transferee shall be vested with all the rights and powers of Lender hereunder with respect to such Collateral so transferred, but with respect to any Collateral not so transferred, Lender shall retain all rights and powers hereby given.

     8.8 Lender’s Duties.

      (a) Lender shall use reasonable care in the custody and preservation of any Collateral in its possession. Without limitation on other conduct which may be considered the exercise of reasonable care, Lender shall be deemed to have exercised reasonable care in the custody and preservation of such Collateral if such Collateral is accorded treatment substantially equal to that which Lender accords its own property, it being understood that Lender shall not have any responsibility for ascertaining or taking action with respect to calls, conversions, exchanges, maturities, declining value, tenders or other matters relative to any Collateral, regardless of whether Lender has or is deemed to have knowledge of such matters; or taking any necessary steps to preserve any rights against any Person with respect to any Collateral. Under no circumstances shall Lender be responsible for any injury or loss to the Collateral, or any part thereof, arising from any cause beyond the reasonable control of Lender.

     (b) Lender may at any time deliver the Collateral or any part thereof to Borrower and the receipt of Borrower shall be a complete and full acquittance for the Collateral so delivered, and Lender shall thereafter be discharged from any liability or responsibility therefor.

      (c) Neither Lender, nor any of its directors, officers, employees, agents, attorneys or any other person affiliated with or representing Lender shall be liable for any claims, demands, losses or damages, of any kind whatsoever, made, claimed, incurred or suffered by Borrower or any other party through the ordinary negligence of Lender, or any of its directors, officers, employees, agents, attorneys or any other person affiliated with or representing Lender.

     8.9 Termination of Security Interests. Upon the payment in full of the Obligations (other than contingent, reimbursement and indemnification obligations for which no claim has been made) and satisfaction of all Borrower’s obligations under this Agreement and the other Loan Documents, and if Lender has no further obligations under its Commitment, the security interest granted hereby shall terminate and all rights to the Collateral shall revert to Borrower. Upon any such termination, the Lender shall, at Borrower’s expense, execute and deliver to Borrower such documents as Borrower shall reasonably request to evidence such termination.

ARTICLE 9 — GENERAL PROVISIONS

     9.1 Notices. Any notice given by any party under any Loan Document shall be in writing and personally delivered, sent by overnight courier, or United States mail, postage prepaid, or sent by facsimile, or other authenticated message, charges prepaid, to the other party’s or parties’ addresses shown on the Supplement. Each party may change the address or facsimile number to which notices, requests and other communications are to be sent by giving written notice of such change to each other party. Notice given by hand delivery shall be deemed received on the date delivered; if sent by overnight courier, on the next Business Day after delivery to the courier service; if by first class mail, on the third Business Day after deposit in the U.S. Mail; and if by facsimile, on the date of transmission.

     9.2 Binding Effect. The Loan Documents shall be binding upon and inure to the benefit of Borrower and Lender and their respective successors and assigns; provided, however, that Borrower may not assign or transfer Borrower’s rights or obligations under any Loan Document. Lender reserves the right to sell, assign, transfer, negotiate or grant participations in all or any part of, or any interest in, Lender’s rights and obligations under the Loan Documents subject to Borrower’s consent; provided that no such consent shall be required (i) if an Event of Default has then occurred and is continuing, or (ii) for any assignment to LLC (as defined below), or (iii) for any collateral assignment for security purposes to an institutional lender providing financing to Lender . In connection with any of the foregoing, Lender may disclose all documents and information which Lender now or hereafter may have relating to the Loans, Borrower, or its business. It is the intention of the parties that, as a “venture capital operating company,” Venture Lending & Leasing IV, LLC (“LLC”), the parent and sole owner of Lender, shall have the benefit of, and the power to independently exercise, those “management rights” provided in Section 5.3. To that end, the references to Lender in Sections 4.2(f), 5.1, 5.2, 5.3 and 5.9(a) hereof shall include LLC, and LLC shall have the right to exercise the advisory, inspection, information and other rights given to lender under those Sections independently of Lender. No amendment, modification, termination or waiver of any provision of this Agreement shall in any event be effective unless the same shall be in writing and signed by Borrower and the Lender; provided, however, that no amendment or modification of this Agreement shall alter or diminish LLC’s rights under the preceding sentence without the consent of LLC.

     9.3 No Waiver. Any waiver, consent or approval by Lender of any Event of Default or breach of any provision, condition, or covenant of any Loan Document must be in writing and shall be effective only to the extent set forth in writing.
