THIS LOAN AND SECURITY AGREEMENT is entered into on the above date between SQUARE 1 BANK (“Lender”), whose address is 000 Xxxxxxxxx Xxxxxx, Xxxxx 000, Xxxxxx, Xxxxx Xxxxxxxx 00000, and the borrowers named above (jointly and severally, the “Borrower”), whose chief executive office is located at the above address (“Borrower’s Address”). The Schedule to this Agreement (the “Schedule”) shall for all purposes be deemed to be a part of this Agreement, and the same is an integral part of this Agreement. (Definitions of certain terms used in this Agreement are set forth in Section 8 below.)

1. LOANS.

1.1 Loans. Lender will make loans to Borrower (the “Loans”), in amounts not to exceed the limits shown on the Schedule (the “Credit Limit”), subject to the provisions of this Agreement and subject to deduction of Reserves for accrued interest and such other Reserves as Lender deems proper from time to time in its Good Faith Business Judgment.

1.2 Interest. All Loans shall bear interest at the interest rate shown on the Schedule from the date made until the date repaid in immediately available funds. All fees payable to the Lender, and all reimbursement to the Lender under Section 9.12 shall bear interest from the date due to the date paid at the interest rate applicable to the Loans. Accrued interest shall be payable monthly, on the last day of the month, and shall be charged to Borrower’s loan account (and the same shall thereafter bear interest at the same rate as the other Loans).

1.3 Overadvances. If at any time or for any reason the total of all outstanding Loans and all other monetary Obligations charged to Borrower’s Loan account exceeds the Credit Limit (an “Overadvance”), Borrower shall immediately pay the amount of the excess to Lender, without notice or demand. Without limiting Borrower’s obligation to repay to Lender the amount of any Overadvance, Borrower agrees to pay Lender interest on the outstanding amount of any Overadvance, on demand, at the Default Rate.

1.4 Fees. Borrower shall pay Lender the fees shown on the Schedule, which are in addition to all interest and other sums payable to Lender and are not refundable.

1.5 Loan Requests. To obtain a Loan, Borrower shall make a request to Lender by facsimile, telephone or electronic mail. Loan requests received after 1:00 PM Eastern Time will be deemed made on the next Business Day. Lender may rely on any telephone request for a Loan given by a person whom Lender believes is an authorized representative of Borrower, and Borrower will indemnify Lender for any loss Lender suffers as a result of that reliance.

1.6 Ancillary Services Sublimit. Subject to the availability of Loans, at any time and from time to time from the date hereof through the Business Day immediately prior to the Maturity Date, Borrower may request the provision of Ancillary Services from Lender. The aggregate amount of the Obligations relating to Ancillary Services at any time shall not exceed the Ancillary Services Sublimit, and availability of Loans shall be reduced by reserves for Ancillary Services in an amount equal to the aggregate amounts of the following (the “Ancillary Services Reserves”): (i) any outstanding and undrawn amounts under all Letters of Credit issued hereunder, (ii) corporate credit card services provided to Borrower, (iii) the total amount of any Automated Clearing House processing reserves, (iv) the applicable Foreign Exchange Reserve Percentage, and (v) any other reserves taken by Lender in connection with other treasury management services requested by Borrower and approved by Lender. In the event at any time there are insufficient Loans available to Borrower for such reserves, Borrower shall deposit and maintain with Lender cash collateral in an amount at all times equal to such deficiency, which shall be held as Collateral for all purposes of this Agreement. In addition, Lender may, in its sole discretion, charge as Loans any amounts for which Lender becomes liable to third parties in connection with the provision of the Ancillary Services. The terms and conditions (including repayment and fees) of such Ancillary Services shall be subject to the terms and conditions of the Lender’s standard forms of application and agreement for the applicable Ancillary Services, which Borrower hereby agrees to execute, to the extent not already executed.

1.7 Letters of Credit. Subject to Section 1.6 above, at the request of Borrower, Lender may, in its Good Faith Business Judgment, issue or arrange for the issuance of Letters of Credit for the account of Borrower, in each case in form and substance satisfactory to Lender in its sole discretion. Borrower shall pay Lender’s standard fees and charges in connection with all Letters of Credit and all other bank charges (including charges of Lender’s letter of credit department) in connection with the Letters of Credit (collectively, the “Letter of Credit Fees”). Any payment by Lender under or in connection with a Letter of Credit shall constitute a Loan hereunder on the date such payment is made. Each Letter of Credit shall have an expiry date no later than one year after the Maturity Date. Borrower hereby agrees to indemnify and hold Lender harmless from any loss, cost, expense, or liability, including payments made by Lender, expenses, and reasonable attorneys’ fees incurred by Lender arising out of or in connection with any Letters of Credit; provided that this indemnity shall not extend to damages proximately caused by the Lender’s own gross negligence or willful misconduct. Borrower agrees to be bound by the regulations and interpretations of the issuer of any Letters of Credit guaranteed by Lender and opened for Borrower’s account or by Lender’s interpretations of any Letter of Credit issued by Lender for Borrower’s account, and Borrower understands and agrees that Lender shall not be liable for any error, negligence, or mistake, whether of omission or commission, in following Borrower’s instructions or those contained in the Letters of Credit or any modifications, amendments, or supplements thereto. Borrower understands that Letters of Credit may require Lender to indemnify the issuing bank for certain costs or liabilities arising out of claims by Borrower against such issuing bank. Borrower hereby agrees to indemnify and hold Lender harmless with respect to any loss, cost, expense, or liability incurred by Lender under any Letter of Credit as a result of Lender’s indemnification of any such issuing bank. The provisions of this Loan Agreement, as it pertains to Letters of Credit, and any other Loan Documents relating to Letters of Credit are cumulative.

1.8 Collateralization of Obligations Extending Beyond Maturity. If Borrower has not secured to Lender’s satisfaction its Obligations with respect to any Ancillary Services by the Maturity Date, then, effective as of such date, without limiting Lender’s other rights and remedies, the balance in any deposit accounts held by Lender and the certificates of deposit or time deposit accounts issued by Lender in Borrower’s name (and any interest paid thereon or proceeds thereof, including any amounts payable upon the maturity or liquidation of such certificates or accounts) in each case in an amount not to exceed the outstanding amount of Obligations with respect to such Ancillary Services, shall automatically secure such obligations to the extent of the then continuing or outstanding Ancillary Services. Borrower authorizes Lender to hold such balances in pledge and to decline to honor any drafts thereon or any requests by Borrower or any other Person to pay or otherwise transfer any part of such balances for so long as the applicable Ancillary Services are outstanding or continue. Without limiting the foregoing, all Obligations relating to Ancillary Services shall be due and payable on the Maturity Date.

2. SECURITY INTEREST. To secure the payment and performance of all of the Obligations when due, Borrower hereby grants to Lender a security interest in all of the following (collectively, the “Collateral”): all right, title and interest of Borrower in and to all of the following, whether now owned or hereafter arising or acquired and wherever located: all Accounts; all Inventory; all Equipment; all Deposit Accounts; all General Intangibles (including without limitation all Intellectual Property); all Investment Property; all Other Property; and any and all claims, rights and

-2-

Square 1 Bank Loan and Security Agreement

interests in any of the above, and all guaranties and security for any of the above, and all substitutions and replacements for, additions, accessions, attachments, accessories, and improvements to, and proceeds (including proceeds of any insurance policies, proceeds of proceeds and claims against third parties) of, any and all of the above, and all Borrower’s books relating to any and all of the above. Notwithstanding anything to the contrary contained in this Section 2, the security interest created by this Agreement shall not extend to, and the term “Collateral” shall not include, any Excluded Property, provided that, if any Excluded Property would have otherwise constituted Collateral, when such property shall cease to be Excluded Property, such property shall be deemed at all times from and after the date hereof to constitute Collateral and the security interest created by this Agreement shall extend to the same.

3. REPRESENTATIONS, WARRANTIES AND COVENANTS OF BORROWER.

In order to induce Lender to enter into this Agreement and to make Loans, Borrower represents and warrants to Lender as follows, and Borrower covenants that the following representations will continue to be true (except to the extent that such representation or warranty relates to a particular date), and that Borrower will at all times comply with all of the following covenants, throughout the term of this Agreement and until all Obligations (other than inchoate indemnity obligations) have been paid and performed in full:

3.1 Corporate Existence and Authority. Borrower is, and will continue to be, duly organized, validly existing and in good standing under the laws of the jurisdiction of its incorporation or organization. Borrower is and will continue to be qualified and licensed to do business in all jurisdictions in which any failure to do so would result in a Material Adverse Change. The execution, delivery and performance by Borrower of this Agreement, and all other documents contemplated hereby (i) have been duly and validly authorized, (ii) are not subject to any consents, which have not been obtained, (iii) are enforceable against Borrower in accordance with their terms (except as enforcement may be limited by equitable principles and by bankruptcy, insolvency, reorganization, moratorium or similar laws relating to creditors’ rights generally), and (iv) do not violate Borrower’s articles or certificate of incorporation, or Borrower’s by-laws, or any law or any material agreement or instrument, which is binding upon Borrower or its property, and (v) do not constitute grounds for acceleration of any indebtedness or obligations in excess of $100,000 in the aggregate, under any agreement or instrument which is binding upon Borrower or its property.

3.2 Name; Trade Names and Styles. As of the date hereof, the name of Borrower set forth in the heading to this Agreement is its correct name. Listed in the Representations are all prior names of Borrower and all of Borrower’s present and prior trade names, as of the date hereof. Borrower shall give Lender 30 days’ prior written notice before changing its name or doing business under any other name. Borrower has complied, and will in the future comply, in all material respects, with all laws relating to the conduct of business under a fictitious business name.

3.3 Place of Business; Location of Collateral. As of the date hereof, the address set forth in the heading to this Agreement is Borrower’s chief executive office. In addition, as of the date hereof, Borrower has places of business and Collateral is located only at the locations set forth in the Representations. Borrower will give Lender at least 30 days prior written notice before opening any additional place of business, changing its chief executive office, or moving any of the Collateral to a location other than Borrower’s Address or one of the locations set forth in the Representations, except that Borrower may maintain sales offices in the ordinary course of business at which not more than a total of $100,000 fair market value of Equipment and Inventory is located.

3.4 Title to Collateral; Perfection; Permitted Liens.

(a) Borrower is now, and will at all times in the future be, the sole owner of all the Collateral, except for items of Equipment which are leased to Borrower, and except for non-exclusive licenses granted by Borrower to its customers in the ordinary course of business. The Collateral now is and will remain free and clear of any and all Liens and adverse claims, except for Permitted Liens and except for adverse claims arising in the future in a total amount less than $200,000, which are (i) in the aggregate less than $100,000 or (ii) resolved in a manner acceptable to Lender in its Good Faith Business Judgment within ten Business Days after they arise. Lender now has, and will continue to have, a first-priority perfected and enforceable security interest in all of the Collateral, subject only to the Permitted Liens, and Borrower will at all times use commercially reasonable efforts to defend Lender and the Collateral against all claims of others.

-3-

Square 1 Bank Loan and Security Agreement

(b) Borrower has set forth in the Representations all of Borrower’s Deposit Accounts as of the date hereof, and Borrower will give Lender five Business Days advance written notice before establishing any new Deposit Accounts, and will cause the institution where any such new Deposit Account is maintained to execute and deliver to Lender a control agreement in form sufficient to perfect Lender’s security interest in the Deposit Account and otherwise satisfactory to Lender in its Good Faith Business Judgment, provided that, in the case of Deposit Accounts subject to Permitted Deposit Account Liens, Borrower shall only be obligated to use commercially reasonable efforts to provide Lender with a perfected security interest in such Deposit Accounts, and such security interest shall be subordinate to the security interest of the holder of the Permitted Deposit Account Lien. Nothing herein limits any requirements which may be set forth in the Schedule as to where Deposit Accounts will be maintained.

(c) In the event that Borrower shall at any time after the date hereof have any commercial tort claims against others, which it is asserting or intends to assert, and in which the potential recovery exceeds $250,000, Borrower shall promptly notify Lender thereof in writing and provide Lender with such information regarding the same as Lender shall request. Such notification to Lender shall constitute a grant of a security interest in the commercial tort claim and all proceeds thereof to Lender, and Borrower shall execute and deliver all such documents and take all such actions as Lender shall request in connection therewith.

(d) Whenever any Collateral is located upon premises in which any third party has an interest, Borrower shall, whenever requested by Lender, use commercially reasonable efforts to cause such third party to execute and deliver to Lender, in form acceptable to Lender, such landlord agreements, waivers, subordinations and other agreements as Lender shall specify in its Good Faith Business Judgment. Without limiting the generality of the foregoing, Borrower shall use commercially reasonable efforts to obtain landlord agreements from the landlord of its premises in Texas in favor of Lender in form acceptable to Lender within 45 days after the date hereof. Borrower will keep in full force and effect, and will comply with all material terms of, any lease of real property where any of the Collateral now or in the future may be located.

(e) Except as disclosed in the Representations, as of the date hereof, Borrower is not a party to, nor is it bound by, any license or other agreement that is important for the conduct of Borrower’s business and that prohibits or otherwise restricts Borrower from granting a security interest in Borrower’s interest in such license or agreement or any other property important for the conduct of Borrower’s business.

(f) Borrower is the sole owner of the Intellectual Property, except for Permitted Liens and non-exclusive licenses granted by Borrower to its customers in the ordinary course of business. To the best of Borrower’s knowledge, (i) each of the registered Copyrights, Trademarks and Patents is valid and enforceable, (ii) no part of the Intellectual Property has been judged invalid or unenforceable, in whole or in part, and (iii) no claim has been made to Borrower that any part of the Intellectual Property violates the rights of any third party except to the extent such claim would not reasonably be expected to cause a Material Adverse Change.

3.5 Maintenance of Collateral. Borrower will maintain the Inventory in good and merchantable condition in all material respects and maintain all other tangible Collateral in good working condition in all material respects (ordinary wear, tear and insured casualty excepted), provided that this sentence shall not apply to Inventory with a value of less than $100,000 in the aggregate. Borrower will not use the Collateral for any unlawful purpose. Borrower will immediately advise Lender in writing of any material loss or damage to the Collateral, within three Business Days after the date such loss or damage occurs.

3.6 Books and Records. Borrower has maintained and will maintain at Borrower’s Address books and records, which are complete and accurate in all material respects, and comprise an accounting system in accordance with GAAP.

3.7 Financial Condition, Statements and Reports. All financial statements now or in the future delivered to Lender have been, and will be, prepared in conformity with GAAP, and now and in the future will, in all material respects, fairly present the results of operations and financial condition of Borrower, in accordance with GAAP, at the times and for the periods therein stated (except for non-compliance with FAS 123R in monthly financial statements, and, in the case of interim financial statements, for the lack of footnotes and subject to year-end adjustments). Between the last date covered by any such statement provided to Lender and the date hereof, there has been no Material Adverse Change.

3.8 Tax Returns and Payments; Pension Contributions. Borrower has timely filed, and will timely file, all required tax returns and reports, and Borrower has timely paid, and will timely pay, all foreign, federal, state and local taxes, assessments, deposits and contributions now or in the future owed by Borrower (except for any inadvertent failure to pay any of the same in an aggregate amount at any time outstanding not to exceed $25,000). Borrower may, however, defer payment of any contested taxes, provided that Borrower (i) in good faith contests Borrower’s obligation to pay the taxes by appropriate proceedings promptly and diligently instituted and conducted, (ii) notifies Lender in writing of the commencement of, and any material development in, the proceedings, and (iii) posts bonds or takes any other steps required to keep the contested taxes from becoming a Lien upon any of the Collateral. As of the date hereof, Borrower is unaware of any claims or adjustments proposed for any of Borrower’s prior tax years which could result in additional taxes becoming due and payable by Borrower. Borrower has paid, and shall continue to pay all amounts necessary to fund all present and future pension, profit sharing and deferred compensation plans in accordance with their terms, and Borrower has not and will not withdraw from participation in, permit partial or complete termination of, or permit the occurrence of any other event with respect to, any such plan which could reasonably be expected to result in any liability of Borrower in an aggregate amount in excess of $100,000, including any liability to the Pension Benefit Guaranty Corporation or its successors or any other governmental agency.

3.9 Compliance with Law. Borrower has, to the best of its knowledge, complied, and will in the future comply, in all material respects, with all provisions of all foreign, federal, state and local laws and regulations applicable to Borrower, including, but not limited to, those relating to Borrower’s ownership of real or personal property, the conduct and licensing of Borrower’s business, and all environmental matters. Borrower has obtained all consents, approvals and authorizations of, made all declarations or filings with, and given all notices to, all governmental authorities that are necessary for the continued operation of Borrower’s business as currently conducted, except where the failure to do so would not reasonably be expected to cause a Material Adverse Change.

3.10 Litigation. As of the date hereof, there is no claim, suit, litigation, proceeding or investigation pending or, to Borrower’s knowledge, threatened in writing against or affecting Borrower in any court or before any governmental agency (or any basis therefor known to Borrower) involving any claim against Borrower of more than $250,000. Borrower will promptly inform Lender in writing of any claim, proceeding, litigation or investigation in the future threatened in writing or instituted against Borrower involving any claim against Borrower of more than $250,000.

3.11 Use of Proceeds. All proceeds of all Loans shall be used solely for Borrower’s working capital. Borrower is not purchasing or carrying any “margin stock” (as defined in Regulation U of the Board of Governors of the Federal Reserve System) and no part of the proceeds of any Loan will be used to purchase or carry any “margin stock” or to extend credit to others for the purpose of purchasing or carrying any “margin stock.”

3.12 Solvency, Payment of Debts. Borrower is able to pay its debts (including trade debts) as they mature; the fair saleable value of Borrower’s assets (including goodwill minus disposition costs) exceeds the fair value of its liabilities; and Borrower is not left with unreasonably small capital after the transactions contemplated by this Agreement.

4. ACCOUNTS.

4.1 Representations Relating to Accounts. Borrower represents and warrants to Lender as follows: Each Account (including Unbilled Accounts) with respect to which Loans are requested by Borrower shall, on the date each Loan is requested and made, (i) represent an undisputed bona fide existing unconditional obligation of the Account Debtor, and (ii) meet the Minimum Eligibility Requirements set forth in Section 8 below.

4.2 Representations Relating to Documents and Legal Compliance. Borrower represents and warrants to Lender as follows: All statements made and all unpaid balances appearing in all invoices, instruments and other documents evidencing the Accounts are and shall be true and correct in all material respects, and all such invoices, instruments and other documents and all of Borrower’s books and records are and shall be genuine and in all material respects what they purport to be. All sales and other transactions underlying or giving rise to each Account shall comply in all material respects with all applicable laws and governmental rules and regulations. To the best of Borrower’s knowledge, all signatures and endorsements on all material documents, instruments, and agreements relating to all Accounts are and shall be genuine, and all such documents, instruments and agreements are and shall be legally enforceable in accordance with their terms.

4.3 Documents relating to Accounts. If requested by Lender, Borrower shall furnish Lender with copies (or, at Lender’s request, originals) of all contracts, orders, invoices, and other similar documents, and all shipping instructions, delivery receipts, bills of lading, and other evidence of delivery, for any goods the sale or disposition of which gave rise to such Accounts, and Borrower warrants the genuineness of all of the foregoing. Borrower shall also furnish to Lender an aged accounts receivable trial balance as provided in the Schedule. In addition, Borrower shall deliver to Lender, on its request, if an Event of Default has occurred and is continuing, the originals of all instruments, chattel paper, security agreements, guarantees and other documents and property evidencing or securing any Accounts, in the same form as received, with all necessary endorsements, and copies of all credit memos.

4.4 [intentionally omitted].

4.5 [intentionally omitted].

4.6 Settlement of Accounts. Borrower shall not forgive (completely or partially), compromise or settle any Account for less than payment in full, or agree to do any of the foregoing, except that Borrower may do so, provided that: (i) Borrower does so in good faith, in a commercially reasonable manner, in the ordinary course of business, and in arm’s length transactions; (ii) no Default or Event of Default has occurred and is continuing; and (iii) taking into account all such discounts, settlements and forgiveness, the total outstanding Loans will not exceed the Credit Limit.

4.7 Returns. Provided no Event of Default has occurred and is continuing, if any Account Debtor returns any Inventory to Borrower, Borrower shall promptly determine the reason for such return and, if Borrower agrees, promptly issue a credit memorandum to the Account Debtor in the appropriate amount. In the event any attempted return occurs after the occurrence and during the continuance of any Event of Default, Borrower shall hold the returned Inventory in trust for Lender, and immediately notify Lender of the return of the Inventory.

4.8 Verification. So long as an Event of Default exists, Lender may, from time to time, verify directly with the respective Account Debtors the validity, amount and other matters relating to the Accounts, by means of mail, telephone or otherwise, either in the name of Borrower or Lender or such other name as Lender may choose, and Lender or its designee may, at any time, notify Account Debtors that it has a security interest in the Accounts.

4.9 No Liability. Lender shall not be responsible or liable for any shortage or discrepancy in, damage to, or loss or destruction of, any goods, the sale or other disposition of which gives rise to an Account, or for any error, act, omission, or delay of any kind occurring in the settlement, failure to settle, collection or failure to collect any Account, or for settling any Account in good faith for less than the full amount thereof, nor shall Lender be deemed to be responsible for any of Borrower’s obligations under any contract or agreement giving rise to an Account. Nothing in this Section 4.9 shall, however, relieve Lender from liability for its own gross negligence or willful misconduct.

5. ADDITIONAL DUTIES OF BORROWER.

5.1 Financial and Other Covenants. Borrower shall at all times comply with the financial and other covenants set forth in the Schedule.

All such casualty insurance policies shall name Lender as a loss payee, and shall contain a lenders loss payee endorsement in form reasonably acceptable to Lender, and all liability insurance policies shall name Lender as an additional insured. Upon receipt of the proceeds of any such casualty insurance, Lender shall apply such proceeds in reduction of the Obligations as Lender shall determine in its sole discretion, except that, provided no Default or Event of Default has occurred and is continuing, Lender shall release to Borrower insurance proceeds with respect to Equipment totaling less than $500,000, which shall be utilized by

Borrower for the replacement of the Equipment with respect to which the insurance proceeds were paid or the acquisition of other assets used or useful in Borrower’s business. Lender may require reasonable assurance that the insurance proceeds so released will be so used.

Borrower shall promptly deliver to Lender copies of all material reports made to insurance companies.

Borrower agrees, at its expense, on request by Lender, to execute all documents and take all actions, as Lender, may, in its Good Faith Business Judgment, deem necessary or useful in order to perfect and maintain Lender’s perfected first-priority security interest in the Collateral (subject only to Permitted Liens), and in order to fully consummate the transactions contemplated by this Agreement.

6. TERM.

6.3 Payment of Obligations. On the Maturity Date or on any earlier effective date of termination, Borrower shall pay in full all Obligations, whether evidenced by installment notes or otherwise, and whether or not all or any part of such Obligations are otherwise then due and payable. Without limiting the generality of the foregoing, if on the Maturity Date, or on any earlier effective date of termination, there are any outstanding Letters of Credit issued by Lender or issued by another institution based upon an application, guarantee, indemnity or similar agreement on the part of Lender, then on such date Borrower shall provide to Lender cash collateral in an amount equal to 100% of the face amount of all such Letters of Credit, plus all interest, fees and cost due or to become due in connection therewith (as estimated by Lender in its Good Faith Business Judgment), to secure all of the Obligations relating to said Letters of Credit, pursuant to Lender’s then standard form cash pledge agreement. Notwithstanding any termination of this Agreement, all of Lender’s security interests in all of the Collateral and all of the terms and provisions of this Agreement shall continue in full force and effect until all Obligations have been paid in full; provided that Lender may, in its sole discretion, refuse to make any further Loans after termination.

Lender shall, at Borrower’s expense, release or terminate all financing statements and other filings in favor of Lender as may be required to fully terminate Lender’s security interests, provided that there are no suits, actions, proceedings or claims pending or threatened against any Person indemnified by Borrower under this Agreement with respect to which indemnity has been or may be sought, upon Lender’s receipt of the following, in form and content satisfactory to Lender: (i) cash payment in full of all of the Obligations, and (ii) written confirmation by Borrower that the commitment of Lender to make Loans under this Agreement has terminated.

Lender shall have the right to conduct such disposition on Borrower’s premises without charge, for such time or times as Lender deems reasonable, or on Lender’s premises, or elsewhere and the Collateral need not be located at the place of disposition. Lender may directly or through any Affiliate purchase or lease any Collateral at any such public disposition, and if permissible under applicable law, at any private disposition.

-11-

Without limiting any of Lender’s rights and remedies, from and after the occurrence and during the continuance of any Event of Default, the interest rate applicable to the Obligations and Letter of Credit Fees shall be increased by an additional three percent per annum (the “Default Rate”).

7.3 Standards for Determining Commercial Reasonableness. Borrower and Lender agree that a sale or other disposition (collectively, “Sale”) of any Collateral which complies with the following standards will conclusively be deemed to be commercially reasonable: (i) notice of the Sale is given to Borrower at least ten days prior to the Sale, and, in the case of a public Sale, notice of the Sale is published at least five days before the date of the Sale in a newspaper of general circulation in the county where the Sale is to be conducted; (ii) notice of the Sale describes the Collateral in general, non-specific terms; (iii) the Sale is conducted at a place designated by Lender, with or without the Collateral being present; (iv) the Sale commences at any time between 8:00 a.m. and 6:00 p.m.; (v) payment of the purchase price in cash or by cashier’s check or wire transfer is required; (vi) with respect to any Sale of any of the Collateral, Lender may (but is not obligated to) direct any prospective purchaser to ascertain directly from Borrower any and all information concerning the same. Lender shall be free to employ other methods of noticing and selling the Collateral, in its discretion, if they are commercially reasonable.

7.4 Investment Property. If an Event of Default has occurred and is continuing, Borrower shall hold all payments on, and proceeds of, and distributions with respect to, Investment Property in trust for Lender, and Borrower shall deliver all such payments, proceeds and distributions to Lender, immediately upon receipt, in their original form, duly endorsed, to be applied to the Obligations in such order as Lender shall determine. Borrower recognizes that Lender may be unable to make a public sale of any or all of the Investment Property, by reason of prohibitions contained in applicable securities laws or otherwise, and expressly agrees that a private sale to a restricted group of purchasers for investment and not with a view to any distribution thereof shall be considered a commercially reasonable sale thereof.

7.5 Power of Attorney. Upon the occurrence and during the continuance of any Event of Default, without limiting Lender’s other rights and remedies, Borrower grants to Lender an irrevocable power of attorney coupled with an interest, authorizing and permitting Lender (acting through any of its employees, attorneys or agents) at any time, at its option, but without obligation, with or without notice to Borrower, and at Borrower’s expense, to do any or all of the following, in Borrower’s name or otherwise, but Lender agrees that if it exercises any right hereunder, it will do so in good faith and in a commercially reasonable manner: (a) execute on behalf of Borrower any documents that Lender may, in its Good Faith Business Judgment, deem advisable in order to perfect and maintain Lender’s security interest in the Collateral, or in order to exercise a right of Borrower or Lender, or in order to fully consummate all the transactions contemplated under this Agreement, and all other Loan Documents; (b) execute on behalf of Borrower, any invoices relating to any Account, any draft against any Account Debtor and any notice to any Account Debtor, any proof of claim in bankruptcy, any Notice of Lien, claim of mechanic’s, materialman’s or other Lien, or assignment or satisfaction of mechanic’s, materialman’s or other Lien; (c) take control in any manner of any cash or non-cash items of payment or proceeds of Collateral; endorse the name of Borrower upon any instruments, or documents, evidence of payment or Collateral that may come into Lender’s possession; (d) endorse all checks and other forms of remittances received by Lender; (e) pay, contest or settle any Lien and adverse claim in or to any of the Collateral, or any judgment based thereon, or otherwise take any action to terminate or discharge the same; (f) grant extensions of time to pay, compromise claims and settle Accounts and General Intangibles for less than face value and execute all releases and other documents in connection therewith; (g) pay any sums required on account of Borrower’s taxes or to secure the release of any Liens therefor, or both; (h) settle and adjust, and give releases of, any insurance claim that relates to any of the Collateral and obtain payment therefor; (i) instruct any third party having custody or control of any books or records belonging to, or relating to, Borrower to give Lender the same rights of access and other rights with respect thereto as Lender has under this Agreement; and (j) take any action or pay any sum required of Borrower pursuant to this Agreement and any other Loan Documents; (k) enter into a short-form intellectual property security agreement consistent with the terms of this Agreement for recording purposes only or modify, in its sole discretion, any intellectual property security agreement entered into between

-12-

Square 1 Bank Loan and Security Agreement

Borrower and Lender without first obtaining Borrower’s approval of or signature to such modification by amending exhibits thereto, as appropriate, to include reference to any right, title or interest in any Copyrights, Patents or Trademarks acquired by Borrower after the execution hereof or to delete any reference to any right, title or interest in any Copyrights, Patents or Trademarks in which Borrower no longer has or claims to have any right, title or interest; and (l) file, in its sole discretion, one or more financing or continuation statements and amendments thereto, relative to any of the Collateral; provided Lender may exercise such power of attorney to sign the name of Borrower on any of the documents described in clauses (k) and (l) above, regardless of whether an Event of Default has occurred, so long as any Obligations are outstanding. Any and all reasonable sums paid and any and all reasonable costs, expenses, liabilities, obligations and attorneys’ fees incurred by Lender with respect to the foregoing shall be added to and become part of the Obligations, shall be payable on demand, and shall bear interest at a rate equal to the highest interest rate applicable to any of the Obligations. In no event shall Lender’s rights under the foregoing power of attorney or any of Lender’s other rights under this Agreement be deemed to indicate that Lender is in control of the business, management or properties of Borrower.

7.6 Application of Proceeds. All proceeds realized as the result of any Sale of the Collateral shall be applied by Lender first to the reasonable costs, expenses, liabilities, obligations and attorneys’ fees incurred by Lender in the exercise of its rights under this Agreement, second to the interest due upon any of the Obligations, and third to the principal of the Obligations, in such order as Lender shall determine in its sole discretion. Any surplus shall be paid to Borrower or other persons legally entitled thereto; Borrower shall remain liable to Lender for any deficiency. If, Lender, in its Good Faith Business Judgment, directly or indirectly enters into a deferred payment or other credit transaction with any purchaser at any Sale of Collateral, Lender shall have the option, exercisable at any time, in its Good Faith Business Judgment, of either reducing the Obligations by the principal amount of purchase price or deferring the reduction of the Obligations until the actual receipt by Lender of the cash therefor.

7.7 Remedies Cumulative. In addition to the rights and remedies set forth in this Agreement, Lender shall have all the other rights and remedies accorded a secured party under the Uniform Commercial Code and under all other applicable laws, and under any other instrument or agreement now or in the future entered into between Lender and Borrower, and all of such rights and remedies are cumulative and none is exclusive. Exercise or partial exercise by Lender of one or more of its rights or remedies shall not be deemed an election, nor bar Lender from subsequent exercise or partial exercise of any other rights or remedies. The failure or delay of Lender to exercise any rights or remedies shall not operate as a waiver thereof, but all rights and remedies shall continue in full force and effect until all of the Obligations have been fully paid and performed.

Each Borrower hereby expressly and unconditionally waives all rights of subrogation, reimbursement and indemnity of every kind against any other Borrower, and all rights of recourse to any assets or property of any other Borrower, and all rights to any collateral or security held for the payment and performance of any Obligations, including (but not limited to) any of the foregoing rights which Borrower may have under any present or future document or agreement with any other Borrower or other person, and including (but not limited to) any of the foregoing rights which Borrower may have under any equitable doctrine of subrogation, implied contract, or unjust enrichment, or any other equitable or legal doctrine. Each Borrower hereby waives any defense based on impairment or destruction of its subrogation or other rights against any other Borrower and waives all benefits which might otherwise be available to it under any statutory or common law suretyship defenses or marshalling rights, now and hereafter in effect.

(c) Consents. Each Borrower hereby consents and agrees that, without notice to or by Borrower and without affecting or impairing in any way the obligations or liability of Borrower hereunder, Lender may, from time to time before or after revocation of this Agreement, do any one or more of the following in Lender’s sole and absolute discretion: (i) accept partial payments of, compromise or settle, renew, extend the time for the payment, discharge, or performance of, refuse to enforce, and release all or any parties to, any or all of the Obligations; (ii) grant any other indulgence to any Borrower or any other person in respect of any or all of the Obligations or any other matter; (iii) accept, release, waive, surrender, enforce, exchange, modify, impair, or extend the time for the performance, discharge, or payment of, any and all property of any kind securing any or all of the Obligations or any guaranty of any or all of the Obligations, or on which Lender at any time may have a Lien, or refuse to enforce its rights or make any compromise or settlement or agreement therefor in respect of any or all of such property; (iv) substitute or add, or take any action or omit to take any action which results in the release of, any one or more other Borrowers or any endorsers or Guarantors of all or any part of the Obligations, including, without limitation one or more parties to this Agreement, regardless of any destruction or impairment of any right of contribution or other right of Borrower; (v) apply any sums received from any other Borrower, any Guarantor, endorser, or co-signer, or from the disposition of any Collateral or security, to any indebtedness whatsoever owing from such person or secured by such Collateral or security, in such manner and order as Lender determines in its sole discretion, and regardless of whether such indebtedness is part of the Obligations, is secured, or is due and payable. Borrower consents and agrees that Lender shall be under no obligation to marshal any assets in favor of Borrower, or against or in payment of any or all of the Obligations. Borrower further consents and agrees that Lender shall have no duties or responsibilities whatsoever with respect to any property securing any or all of the Obligations. Without limiting the generality of the foregoing, Lender shall have no obligation to monitor, verify, audit, examine, or obtain or maintain any insurance with respect to, any property securing any or all of the Obligations.

(d) Independent Liability. Each Borrower hereby agrees that one or more successive or concurrent actions may be brought hereon against Borrower, in the same action in which any other Borrower may be sued or in separate

-25-

actions, as often as deemed advisable by Lender. Each Borrower is fully aware of the financial condition of each other Borrower and is executing and delivering this Agreement based solely upon its own independent investigation of all matters pertinent hereto, and Borrower is not relying in any manner upon any representation or statement of Lender with respect thereto. Each Borrower represents and warrants that it is in a position to obtain, and each Borrower hereby assumes full responsibility for obtaining, any additional information concerning any other Borrower’s financial condition and any other matter pertinent hereto as Borrower may desire, and Borrower is not relying upon or expecting Lender to furnish to it any information now or hereafter in Lender’s possession concerning the same or any other matter.

(e) Subordination. All indebtedness of a Borrower now or hereafter arising held by another Borrower is subordinated to the Obligations and the Borrower holding the indebtedness shall take all actions reasonably requested by Lender to effect, to enforce and to give notice of such subordination.
