Lender has an office at ▇▇▇ ▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇^▇▇ ▇▇▇▇▇, ▇▇▇ ▇▇▇▇▇▇▇▇▇, ▇▇ ▇▇▇▇▇. Borrower is a corporation organized and existing under the laws of the state of Delaware.

1. CREATION OF SECURITY INTEREST; ADVANCE OF LOAN AND OTHER INVESTMENT MATTERS.

(a) Security Interest. Borrower grants to Lender, its successors and assigns, a security interest in and against the Collateral (as that term is defined herein) (“Lender’s Lien”). This security interest is given to secure the payment and performance of all debts, obligations and liabilities of any kind whatsoever of Borrower to Lender, now existing or arising in the future, including but not limited to the payment and performance of certain Loan Schedules from time to time executed by Borrower substantially in the form set forth in Schedule C (collectively “Loan Schedules” and each a “Loan Schedule”), and any renewals, extensions and modifications of such debts, obligations and liabilities (such Loan Schedules, debts, obligations and liabilities are called the “Indebtedness”). Any reference herein to a “Loan” shall mean any Loan Schedule, as it incorporates by reference all the terms and conditions of this Agreement and any riders, exhibits or addendum thereto. Lender shall retain Lender’s Lien on all Loans until Borrower has performed all obligations and paid in full all amounts due under all Loans (other than any unasserted claims for indemnification or expense reimbursement).

(b) Advance of Loan. At Borrower’s written request pursuant to a Request for Advance in the form set forth in Schedule D, Lender will advance Borrower an amount, (the “Advance”), in an aggregate amount not to exceed $3,000,000 for use by Borrower as general working capital, (the “Working Capital Line”). Lender’s obligation to make the Advance under the Working Capital Line will be at its sole discretion and in any event, will be subject to the following conditions precedent (i) through (viii): (i) Lender and Borrower shall have entered into mutually acceptable Loan documentation, along with such other ancillary documents and instruments as may be reasonably required by Lender in connection with the Advance under the Working Capital Line, including corporate resolutions and incumbency certificates, or other documents evidencing the Borrower’s authority to execute and deliver the Loan (substantially in the form set forth in Schedule E or other form reasonably acceptable to Lender), evidence of insurance pursuant to “Accord” certificates (pursuant to the request set forth in Schedule F), appropriate waivers or agreements (each a “Waiver”) from all Collateral lien-holders and entities in control of the real property on which Collateral with a fair market value in excess of $50,000 is located including landlords and co-location facilities, but excluding entities and facilities performing Borrower’s drug trials and to which raw materials and goods are shipped, until products produced by such entities and facilities can be classified as “inventory” under generally accepted accounting principles (“GAAP”) and the Uniform Commercial Code as from time to time in effect in the State of California (the “UCC”) (substantially in the form set forth in Schedule H and Schedule I, respectively, or other form reasonably acceptable to Lender), provided, however, with respect to each Waiver, Borrower shall have sixty (60) days after the effective date of this Agreement to obtain and deliver the appropriate Waiver from its landlord, and Borrower and Lender agree if the required Waiver is either missing or does not include language reasonably satisfactory to Lender which provides to Lender an independent means of access to the Collateral, Borrower shall pay to Lender, as additional security, cash in an amount equal to one month’s Basic Loan Payment (“Additional Security”), which deposit will be applied to the next Basic Loan Payment due after the required Waiver is provided and if the required Waiver is not provided, Lender shall apply the

Additional Security to Borrower’s last Basic Loan Payment if no Event of Default has occurred; (ii) Borrower shall have requested an Advance on personal property that will become Collateral to be placed under a Loan by executing a Request for Advance, and a list of Borrower’s major equipment collateral by make, model, serial number, purchase price, purchase date and location, provided, however, Borrower agrees that this list is not intended in any way to limit Lender’s Lien only to items of equipment Collateral so listed; (iii) Borrower shall have authorized Lender to file UCC-1 financing Statements; (iv) Borrower shall have executed and delivered to Lender a Loan Schedule for the aggregate principal amount of such Advance; (v) Borrower shall have full legal right, title, and interest in and to the Collateral, free and clear of all liens, claims, and encumbrances, whatsoever, other than Permitted Liens; (vi) all representations and warranties of Borrower contained in Section 2 of this Agreement are true and correct in all material respects as of the date the Loan is advanced except for any representations and warranties that expressly refer to an earlier date, in which case such representations and warranties shall have been true and correct in all material respects as of such earlier date; (vii) there shall not exist under the Loan any Event of Default, or any condition, event, or act which with notice or lapse of time would become an Event of Default; and (viii) there has not been, in Lender’s opinion, any material adverse change or event since the date of the Proposal Letter dated August 1, 2013 (“Proposal Letter”), with respect to the Advance, which, in the judgment of Lender, would impair the ability of Borrower to perform its obligations hereunder. Lender agrees that in the event Lender at its discretion opts not to make an Advance under this Agreement after an Advance is requested by Borrower and all conditions precedent set forth in this Section 1(b) have been met by Borrower, the Warrant, which shall initially be based upon the Working Capital Line of $3,000,000, shall be automatically reduced by the number of shares which equate to the proportion of the amount of the Working Capital Line not funded by Lender. Lender shall provide a certificate of adjustment indicating the adjustment to the Warrant at such time within ten (10) days of the request of Borrower. Borrower agrees, however, that the Warrant shall not be so reduced in the event Lender is ready, willing and able to make Advances to Borrower under this Agreement but Borrower chooses not to request the Advances. In the event the Warrant has been net exercised when any reduction in shares occurs, Lender shall forfeit and return to Borrower that number of shares which equate to the proportion of the Working Capital Line not funded by Lender at its discretion. To the extent Lender has purchased the Warrant shares at the exercise price for cash when any reduction in shares occurs, Borrower shall have the right to repurchase from Lender in cash at the exercise price paid by Lender that number of shares which equate to the proportion of the Working Capital Line not funded by Lender at its discretion.

(c) Loan Payment. A daily loan payment (“Daily Loan Payment”) shall accrue from the Advance Date multiplied by the number of days from (and including) the Advance Date to (but not including) the Commencement Date and shall be due and payable on the Commencement Date. The Basic Loan Payment payable hereunder during the Basic Loan Term is as set forth in the Loan Schedule. Lender and Borrower agree that the Basic Loan Payment described in the Loan Schedule has a corresponding yield relationship to the U.S. Treasury obligation with the closest equivalent maturity as the applicable Basic Loan Term (“Index Instrument”), as reported in The Wall Street Journal Online on the date of, and quoted in, Lender’s Proposal Letter, and consequently, the Basic Loan Payment, Loan Rate Factor, and Balance Due Values Table may be adjusted upward to provide for any increase in the reported yield of the Index Instrument over 0.845%, and downward to provide for a decrease in the yield of the Index Instrument, provided such adjustment shall never be based on a yield that is less than 0.845% by the Lender on the date of preparation of the Loan Schedule, or alternatively, on the funding date by a Notification of Loan Payment Adjustment amendment prepared thereafter, to reflect a change on such date in the reported yield of the U.S. Treasury obligation, with the equivalent term of the U.S. Treasury obligation quoted in the Proposal Letter (or the closest term to such original U.S. Treasury obligation in the event an identical term issue is not reported, and in the event that two or more comparison Treasury obligations are quoted with identical maturities, then with the “Asked” price which is closest to par) in order to preserve Lender’s anticipated corresponding yield relationship. Except as may otherwise be provided in any Loan Schedule, Basic Loan Payment shall begin to accrue on the Commencement Date and shall be due and payable by Borrower on the first day of each period (advance) or

the last day (arrears) of each period, as set forth in the applicable Loan Schedule. In addition to the Basic Loan Payment Borrower shall pay Daily Loan Payment due as indicated in this Loan Agreement, or on any Loan Schedule, or any Rider hereto or thereto. All Loan Payments due by Borrower hereunder are absolute and unconditional obligations of Borrower which may not be abated or offset for any reason whatsoever.

(d) Stock Warrant. Concurrently with execution of this Agreement by the parties, Borrower will issue to Lender a Series B Preferred warrant based on four and three quarters percent (4.75%) of the Working Capital Line, exercisable for $142,500 worth of shares of Borrower’s Series B Preferred Stock at an exercise price of $0.048961 per share (the “Warrant”). Borrower and Lender hereby acknowledge and agree that the Warrant to purchase stock transferred to Lender is part of an investment unit within the meaning of Section 1273(c)(2) of the Internal Revenue Code which includes the Loans entered into hereunder. Borrower and Lender further agree as between Borrower and Lender, that the fair market value of the Warrant is equal to US$100 and that, pursuant to Treas. Reg. § 1.1273-2(h), US$100 of the issue price of the investment unit will be allocable to the Warrant and the balance shall be allocable to the Loans. Borrower and Lender agree to prepare their federal income tax returns in a manner consistent with the foregoing agreement and, pursuant to Treas. Reg. § 1.1273, the original issue discount on the Loans shall be considered to be zero.

(e) Investment Right. If Lender advances a Loan under the Working Capital Line to Borrower, then Borrower agrees that Lender will have the right (but not the obligation) to invest up to $500,000.00 in cash in a private equity round, in which Borrower will issue equity securities ranking senior to Series B-1 preferred stock, par value $0.00001 per share, of Borrower (such senior equity securities, the “Senior Securities” and such private equity round, the “Qualified Financing Round”), to purchase the same Senior Securities at the same purchase price per Senior Security paid in cash by the other investors participating therein (the “Purchase Price”), and, to the extent Lender does not invest the full $500,000.00 in one such Qualified Financing Round, Lender shall have the right to invest any balance remaining in Borrower’s subsequent Qualified Financing Rounds at the same Purchase Price offered to investors in such subsequent Qualified Financing Rounds. The Lender may exercise the foregoing investment right by (i) delivering written notice thereof to the Company no less than five (5) days prior to the investment, and (ii) within one (1) day (or such other period of time as may be mutually agreed by the parties) after Lender has provided notice of its intent to invest in the equity round, providing Borrower with funds for the Lender’s investment and executed copies of all stock purchase agreements, voting agreements, investor rights agreements and other documents entered into by other investors participating in the equity round. The investment right of Lender under this Section 1(e) shall not apply to the issuance by Borrower of any Exempted Securities (as defined in Borrower’s Amended and Restated Certificate of Incorporation, as amended from time to time (the “Restated Certificate”)) and shall terminate and be of no further force or effect immediately prior to (i) the consummation of an initial public offering of capital stock of Borrower, (ii) the date that the Company first becomes subject to the periodic reporting requirements of Section 12(g) or 15(d) of the Securities Exchange Act of 1934, as amended, or (iii) the Deemed Liquidation Event (as defined in the Restated Certificate) of Borrower, whichever occurs first.

(f) Prepayment Option. So long as no Event of Default shall exist and be continuing, Borrower may elect to terminate any outstanding Loan in whole or in part by paying to Lender in immediately available funds the Balance Due Value set forth in the applicable Loan Schedule for the payment period immediately preceding the date of prepayment, and any outstanding fees, taxes, costs or other reimbursements owing to Lender (the “Prepayment Option”). In the event Borrower elects to exercise its Prepayment Option, Borrower shall give Lender at least five (5) days prior written notice of the proposed prepayment date and such prepayment shall be made as of the regularly scheduled Basic Loan Payment date. Upon receipt by Lender of all amounts due under the Loan (other than any unasserted claims for indemnification or expense reimbursement), Lender shall, at Borrower’s cost and expense, execute such further documents and take such further actions as may be necessary to affect the release of its security interest in the Collateral under the

terminated Loan Schedule, including duly executing and delivering UCC termination statements for filing in any relevant jurisdictions. Nothing in this paragraph is intended to extinguish Lender’s Warrant or Lender’s right to indemnifications which by their nature survive the termination of the Loan.

Borrower shall not sell, transfer, assign, mortgage, pledge, lease, grant a security interest in, or encumber any of its Intellectual Property, or enter into any agreement, document, instrument or other arrangement (except with or in favor of Lender) with any entity which directly or indirectly prohibits or has the effect of prohibiting Borrower from selling, transferring, assigning, mortgaging, pledging, leasing, granting a security interest in or upon, or encumbering any of Borrower’s Intellectual Property; provided, however, that Borrower may grant exclusive and non-exclusive licenses with respect to components of Borrower’s Intellectual Property in connection with joint ventures and corporate collaborations in the ordinary course of Borrower’s business and Borrower acknowledges that it has granted to Lender a lien in all licensing or royalty revenue with respect thereto. If Borrower at any time violates its agreement set forth in this Section 4(e), Lender is hereby automatically granted by Borrower a concurrent security interest in Borrower’s Intellectual Property.

(f)

Transactions with Affiliates. Borrower shall not, without the prior written consent of Lender, directly or indirectly enter into or permit to exist any material transaction with any Affiliate of Borrower except for transactions that are in the ordinary course of Borrower’s business, upon fair and reasonable terms that are no less favorable to Borrower than would be obtained in an arm’s length transaction with a nonaffiliated Person.

(g)

Change in Management. Borrower shall not, without providing prompt written notice to Lender, change the persons holding the offices of Chief Executive Officer or Chief Financial Officer. In the event of the resignation of the Chief Executive Officer or Chief Financial Officer, Borrower agrees to identify a suitable replacement for such individual or individuals within ninety (90) calendar days, and any such individual or individuals so identified shall be approved by Borrower’s Board of Directors.

(h)

Disposition of Collateral. Without the prior written consent of Lender, Borrower shall not (i) remove any of the Collateral from the continental United States except raw materials and goods used in Borrower’s drug tests which are shipped to foreign entities and facilities, or (ii) sell, rent, lease, mortgage, license, grant a security interest in or otherwise transfer or encumber any of the Collateral, except for (a) Permitted Liens, (b) sales of Inventory in the ordinary course of business, (c) Permitted Investments, (d) sales, assignments, transfers and other dispositions of accounts receivable in connection with the compromise, settlement or collection thereof consistent in the ordinary course of business and not for purposes of financing, (e) leases or subleases entered into in the ordinary course of business, to the extent that they do not materially interfere with the business of Borrower, (f) dispositions resulting from any casualty or other insured damage to, or any taking under power of eminent domain or by condemnation or similar proceeding of, any property or asset of Borrower and (g) transfers of worn out or obsolete equipment Collateral and (iii) Borrower shall provide to Lender in conjunction with the list of fixed assets required pursuant to Section 6(e) of this Agreement, information regarding any transfers of any items of worn out or obsolete equipment Collateral valued in excess of $20,000.

(i)

Change in Control. EXCEPT FOR PERMITTED TRANSACTIONS, BORROWER SHALL NOT SELL, CONVEY, TRANSFER, PART WITH POSSESSION, OR ASSIGN OR OTHERWISE ENCUMBER THIS LOAN OR ANY OF THE COLLATERAL OR ANY OF ITS RIGHTS HEREUNDER OR SUBLEASE THE EQUIPMENT COLLATERAL, OR SUFFER A CHANGE IN CONTROL, WITHOUT THE PRIOR WRITTEN CONSENT OF LENDER (SAID CONSENT NOT TO BE UNREASONABLY WITHHELD). EXCEPT AS PERMITTED HEREIN, ANY SUCH PURPORTED TRANSACTION SHALL BE NULL AND VOID AND OF NO FORCE AND EFFECT. An affiliate that is a subsidiary may merge or consolidate into another subsidiary or into Borrower.

For purposes of this Loan, “Permitted Transaction” shall mean (i) Permitted Liens; (ii) dispositions of Collateral made concurrently with the exercise of Borrower’s Prepayment Option with respect to Equipment Collateral in accordance with the immediately succeeding paragraph; (iii) any Change in Control in which the surviving entity after such Change in Control has a tangible net worth equal to or greater than that of the Borrower as of the date of the Change in Control, which shall be based on pro forma financial statements utilizing, in Lender’s reasonable opinion, reasonable assumptions in the preparation thereof by Borrower and provided by Borrower to Lender at least five (5) Business Days before such Change in Control, and the financial condition of such entity will enable it, in Lender’s reasonable opinion, based on said financial statements, to meet all obligations to Borrower’s creditors, including its obligations under the Loan, as they become due for the remaining term of the Loan; and (iv) each other transaction expressly permitted under this Agreement and the other Debt Documents. No permitted assignment or sublease shall relieve Borrower of any of its obligations hereunder without the express written consent of Lender.

Prepayment Requirement. In the event Lender in good faith does not give prior written consent to any event set forth in this Section 4(i), and such event does not constitute a Permitted Transaction, Borrower shall prepay in full the Loan Schedule entered into under this Agreement affected by such event by paying to Lender the Balance Due Value as of the Basic Loan Payment date immediately preceding the consummation of any event described in this Section 4(i) plus any other amounts outstanding and owed to Lender under such Loan Schedule. Upon receipt by Lender of all amounts due under the applicable Loan Schedule (other than any unasserted claims for indemnification or expense reimbursement), Lender shall, at Borrower’s sole cost and expense, execute such further documents and take such further actions as may be necessary to affect the release of its security interests in the applicable Collateral, including duly executing and delivering UCC termination statements for filing in any relevant jurisdictions or terminating account control agreements. Nothing in this paragraph is intended to extinguish Lender’s Warrant or Lender’s right to indemnifications which by their nature survive the termination of this Agreement and the Loan Schedule.

5. INSURANCE.

(a)

Risk of Loss. Borrower shall at all times bear the entire risk of any loss, theft, damage to, or destruction of, any of the Collateral from any cause whatsoever.

(b)

Insurance Requirements. Borrower agrees to maintain general liability insurance and to keep the Collateral insured against loss or damage by fire and extended coverage perils, theft, burglary, risk of loss by collision (for any or all Collateral which are vehicles) and such other risks as Lender may reasonably require. The liability insurance coverage shall be in an amount standard for companies similar to Borrower in Borrower’s industry in Borrower’s geographic region. The property insurance coverage shall be in an amount no less than the full replacement value of the Collateral. All insurance policies shall be in a form, with companies and with deductible amounts reasonably acceptable to Lender. Borrower shall deliver to Lender policies or certificates of insurance evidencing such coverage. Each policy shall name Lender as a loss payee and an additional insured, shall provide for coverage to Lender regardless of the breach by Borrower of any warranty or representation made therein, shall not be subject to co-insurance, and shall provide that coverage may not be canceled or altered by the insurer except upon thirty (30) days prior written notice to Lender. Borrower appoints Lender as its attorney-in-fact to make proof of loss, claim for insurance and adjustments with insurers, and to receive payment of and execute or endorse all documents, checks or drafts in connection with insurance payments, provided that Lender shall not act as Borrower’s attorney-in-fact unless Borrower is in default. If any item of Collateral is materially damaged or suffers a casualty event, Borrower shall give to Lender prompt notice thereof. Borrower shall determine within twenty (20) days after the date on which such damage or casualty event occurs whether such item of Collateral can be repaired. If Borrower determines that such item of Collateral can be repaired with commercially reasonable efforts, Borrower shall cause such item of Collateral to be promptly repaired. If Borrower determines that such item of Collateral cannot be repaired with commercially reasonable efforts, Borrower shall either (i) promptly replace such item of Collateral with equipment useful in the business of Borrower of equal or greater value free and clear of all liens and encumbrances except for Permitted Liens and the Loan with respect to such Collateral shall continue in full force and effect as though such damage or destruction has not occurred, or (ii) pay to Lender an amount equal to the Balance Due Value for the item of Collateral for the Basic Loan Payment due date immediately preceding such damage or casualty event and the applicable Loan will terminate with respect to such item of Collateral and the Basic Loan Payment under the applicable Loan Schedule will be reduced thereafter pro rata by the original cost of the item of Collateral suffering such damage or loss. All proceeds of insurance received by Lender, the designated loss payee or Borrower under any insurance policy shall be applied to the cost of any such repair or replacement so long as no Event of Default has occurred and is continuing at the time such proceeds are received.

6. REPORTS.

(a)

Notice of Events. Borrower shall promptly notify Lender of (i) any change in the name of Borrower, (ii) any change in the state of its incorporation or registration, (iii) any relocation of its chief executive offices, (iv) any material amount of Collateral being lost, stolen, missing, destroyed, materially damaged or worn out, or (v) any lien, claim or encumbrance other than Permitted Liens attaching to or being made against any of the Collateral.

(b)

Financial Statements, Reports and Certificates. (i) Borrower will deliver to Lender within one hundred and twenty (120) days of the close of each fiscal year of Borrower, Borrower’s complete unaudited financial statements including a balance sheet, income statement, statement of shareholders’ equity and statement of cash flows; provided that Borrower shall provide a copy of Borrower’s audited financial statements within 5 business days of when the same shall become available to Borrower, each prepared in accordance with generally accepted accounting principles consistently applied, certified by a recognized firm of certified public accountants reasonably satisfactory to Lender (it being agreed that PricewaterhouseCoopers LLP or any of the other “big four” accounting firms is satisfactory to Lender). (ii) Borrower will deliver to Lender copies of Borrower’s quarterly unaudited financial statements including a balance sheet, income statement and statement of cash flows, each prepared by Borrower in accordance with generally accepted accounting principles consistently applied (except for the absence of notes thereto and of normal year-end audit adjustments) within sixty (60) days after the close of each of Borrower’s fiscal quarters. (iii) Borrower will deliver to Lender copies of Borrower’s monthly unaudited financial statements including a company prepared balance sheet, income statement and cash flow statement covering Borrower’s operations during such period, within thirty (30) days after the close of each month. (iv) So long as there are amounts due Lender under this Loan, Borrower shall supply Lender with such other financial and operating performance data as is provided to its outside investors or commercial lenders and, if applicable, required to be provided to shareholders by the Security and Exchange Commission.

(c)

Certification of Financial Information. All reports, certificates, schedules, notices and financial information (other than any projections or other forward-looking information) submitted by Borrower to the Lender pursuant to this Agreement shall be certified as true and correct in all material respects by the president or chief financial officer of Borrower.

(d)

Receivables. Upon the written request of Lender, but no more frequently than once per month unless an Event of Default has occurred and is continuing, Borrower shall deliver to the Lender schedules of all outstanding Receivables. Such schedules shall be in form reasonably satisfactory to the Lender and shall show the age of such Receivables in intervals of not more than thirty (30) days, and contain such other information and be accompanied by such supporting documents as the Lender may from time to time reasonably prescribe. The Borrower shall also deliver to the Lender, upon Lender’s request, no more frequently than once per month unless an Event of Default has occurred and is continuing copies of the Borrower’s invoices, sales journals, evidences of shipment or delivery and such other schedules and information as the Lender may reasonably request. The items to be provided under this Section are to be prepared and delivered to the Lender from time to time solely for its convenience in maintaining records of the Collateral and the Borrower’s failure to give any of such items to the Lender shall not affect, terminate, modify or otherwise limit the Lender’s security interest granted herein.

(e)

Quarterly Asset List. Within forty-five (45) days after the close of each of Borrower’s fiscal quarters, at the same time as Borrower delivers to Lender its quarterly financial statements, Borrower shall deliver to Lender a current list of all Equipment Collateral.

7. FURTHER ASSURANCES.

(a)

Further Assurances Regarding Security Interests. Borrower shall, upon request of Lender, furnish to Lender such further information, execute and deliver to Lender such documents and instruments (including, without limitation, Uniform Commercial Code financing statements) and shall do such other acts and things as Lender may at any time reasonably request relating to the perfection or

protection of the security interest created by this Agreement or for the purpose of carrying out the intent of this Agreement. To the extent Lender has filed Uniform Commercial Code Financing Statements prior to the execution of this Agreement by Borrower, Borrower hereby ratifies and confirms the completion and filing of any Uniform Commercial Code Financing Statements by Lender occurring prior to the execution by Borrower of this Agreement. Without limiting the foregoing, Borrower shall cooperate and do all acts reasonably deemed necessary or advisable by Lender to continue in Lender a perfected first security interest in the Collateral, and, except as expressly permitted under this Agreement or any other Loan Document, shall obtain and furnish to Lender any subordinations, releases, landlord waivers, lessor waivers, mortgagee waivers, or control agreements, and similar documents as may be from time to time reasonably requested by, and in form and substance reasonably satisfactory to, Lender. If Borrower shall at any time acquire a commercial tort claim, as defined in the Code, Borrower shall immediately notify Lender in writing signed by Borrower of the brief details thereof and grant to Lender in such writing a security interest therein and in the proceeds thereof, all upon the terms of this Agreement, with such writing to be in form and substance reasonably satisfactory to Lender.

(b)

Authorization To File Financial Statements. Except as expressly permitted under this Agreement or any other Loan Document, Borrower shall perform any and all acts reasonably requested by the Lender to establish, maintain and continue the Lender’s security interest and liens in the Collateral, including but not limited to, executing or authenticating financing statements and such other instruments and documents when and as reasonably requested by the Lender. Borrower hereby authorizes Lender through any of Lender’s employees, agents or attorneys to file any and all financing statements, including, without limitation, any original filings, continuations, transfers or amendments thereof required to perfect Lender’s security interest and liens in the Collateral under the UCC without authentication or execution by Borrower.

(c)

Indemnification. Borrower shall indemnify and defend the Lender, its successors and assigns, and their respective directors, officers and employees (collectively, “Indemnitees”), from and against all claims, actions and suits (including, without limitation, related attorneys’ fees) of any kind whatsoever arising, directly or indirectly, in connection with any of the Collateral or the Debt Documents; provided that notwithstanding the foregoing, in no event shall Borrower be required to indemnify any Indemnitee for any claims, actions or suits arising from the gross negligence or willful misconduct of any Indemnitee.

Borrower shall also pay to Lender a facility fee equal to 1% of the Working Capital Line equal to $30,000.00.

(viii)

Any of the Collateral is subjected to attachment, execution, levy, seizure or confiscation in any legal proceeding or otherwise, or if any legal or administrative proceeding is commenced against Borrower or any of the Collateral, which in the good faith judgment of Lender subjects any of the Collateral to a material risk of attachment, execution, levy, seizure or confiscation and no bond is posted or protective order obtained to remove the risk of same;

(b)

Acceleration. If an Event of Default has occurred, Lender, at its option, may declare any or all of the Indebtedness to be immediately due and payable, without demand or notice to Borrower or any Guarantor (provided that if there is a default as a result of a bankruptcy or insolvency all Indebtedness shall become immediately due and payable without any action by Lender) and recover from Borrower as liquidated damages for loss of a bargain and not as a penalty, an amount equal to the Balance Due with respect to any Loan Schedule calculated as of the payment date preceding the date that the event which resulted in the Event of Default occurred which payment shall become immediately due and payable. The accelerated obligations and liabilities shall bear interest (both before and after any judgment) until paid in full at the lower of thirteen percent (13 %) per annum or the maximum rate not prohibited by applicable law.

(c)

Rights and Remedies. Upon the occurrence of an Event of Default, Lender shall have all of the rights and remedies of a Lender under the Code, and under any other applicable law. Without limiting the foregoing, upon the occurrence of an Event of Default, Lender shall have the right to do all of the following: (i) notify any Account Debtor of Borrower or any obligor on any instrument which constitutes part of the Collateral to make payment to the Lender, (ii) with or without legal process, enter any premises where the Collateral may be and take possession of and remove the Collateral from the premises or store it on the premises, (iii) sell the Collateral at public or private sale, in whole or in part, and have the right to bid and purchase at said sale, (iv) to instruct the Third Party Institution maintaining any deposit account or securities account subject to a control agreement in favor of Lender to transfer the funds in such account to any account of the Lender, or (v) lease or otherwise dispose of all or part of the Collateral, applying proceeds from such disposition to the obligations then in default, provided, however, Borrower hereby agrees that, in any event, it will be liable for any deficiency after any lease or other disposition of the Collateral. If requested by Lender, Borrower shall promptly assemble the Collateral and make it available to Lender at a place to be designated by Lender, which is reasonably convenient to both parties. Lender may also render any or all of the Collateral unusable at the Borrower’s premises and may dispose of such Collateral on such premises without liability for rent or costs. Any notice that Lender is required to give to Borrower under the Uniform Commercial Code of the time and place of any public sale or the time after which any private sale or other intended disposition of the Collateral is to be made shall be deemed to constitute reasonable notice if such notice is given to the last known address of Borrower at least ten (10) days prior to such action. Upon the occurrence and during the continuation of an Event of Default, Borrower hereby appoints Lender as Borrower’s attorney-in-fact, with full authority in Borrower’s place and stead and in Borrower’s name or otherwise, from time to time in Lender’s sole and arbitrary discretion, to take any action and to execute any instrument which Lender may deem necessary or advisable to accomplish the purpose

of this Agreement. Lender may ship, reclaim, recover, store, finish, maintain, repair, prepare for sale, advertise for sale, and sell (in the manner provided for herein) the Collateral. In connection therewith, upon the occurrence and during the continuation of an Event of Default, Lender and its agents and any purchasers at or after foreclosure are hereby granted a non-exclusive, irrevocable, perpetual, fully paid, royalty-free license or other right, solely pursuant to the provisions of this Section 8, to use, without charge, Borrower’s Intellectual Property, including without limitation, labels, patents, copyrights, rights of use of any name, trade secrets, trade names, trademarks, service marks, and advertising matter, or any property of a similar nature, now or at any time hereafter owned or acquired by Borrower or in which Borrower now or at any time hereafter has any rights; provided, however, such license shall only be exercisable in connection with the disposition of Collateral upon Lender’s exercise of its remedies hereunder.

(d)

Application of Proceeds. Proceeds from any sale or lease or other disposition shall be applied: first, to all costs of repossession, storage, and disposition including without limitation attorneys’, appraisers’, and auctioneers’ fees; second, to discharge the obligations then in default; third, to discharge any other Indebtedness of Borrower to Lender, whether as obligor, endorser, guarantor, surety or indemnitor; fourth, to expenses incurred in paying or settling liens and claims against the Collateral; and lastly, to Borrower or the Person legally entitled thereto, if there exists any surplus. Borrower shall remain fully liable for any deficiency.

(e)

Fees and Costs. Borrower agrees to pay all reasonable attorneys’ fees and other itemized out-of-pocket costs incurred by Lender in connection with the enforcement, assertion, defense or preservation of Lender’s rights and remedies under this Agreement, or if prohibited by law, such lesser sum as may be permitted. Borrower further agrees that such fees and costs shall constitute Indebtedness.

(f)

Remedies Cumulative. Lender’s rights and remedies under this Agreement or otherwise arising are cumulative and may be exercised singularly or concurrently. Neither the failure nor any delay on the part of the Lender to exercise any right, power or privilege under this Agreement shall operate as a waiver, nor shall any single or partial exercise of any right, power or privilege preclude any other or further exercise of that or any other right, power or privilege. LENDER SHALL NOT BE DEEMED TO HAVE WAIVED ANY OF ITS RIGHTS OR REMEDIES, WHETHER HEREINBEFORE OR HEREINAFTER EXISTING, PAST OR PRESENT, UNDER THIS AGREEMENT OR UNDER ANY OTHER AGREEMENT, INSTRUMENT OR PAPER SIGNED BY BORROWER UNLESS SUCH WAIVER IS EXPRESSED IN WRITING AND SIGNED BY LENDER. A waiver on any one occasion shall not be construed as a bar to or waiver of any right or remedy on any future occasion.

(g)

WAIVER OF JURY TRIAL. TO THE EXTENT PERMITTED BY LAW, BORROWER AND LENDER UNCONDITIONALLY WAIVE THEIR RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF THIS AGREEMENT, ANY OF THE OTHER DEBT DOCUMENTS, ANY OF THE INDEBTEDNESS SECURED HEREBY, ANY DEALINGS BETWEEN BORROWER AND LENDER RELATING TO THE SUBJECT MATTER OF THIS TRANSACTION OR ANY RELATED TRANSACTIONS, AND/OR THE RELATIONSHIP THAT IS BEING ESTABLISHED BETWEEN BORROWER AND LENDER. THE SCOPE OF THIS WAIVER IS INTENDED TO BE ALL ENCOMPASSING OF ANY AND ALL DISPUTES THAT MAY BE FILED IN ANY COURT. THIS WAIVER IS IRREVOCABLE. THIS WAIVER MAY NOT BE MODIFIED EITHER ORALLY OR IN WRITING. THE WAIVER ALSO SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS

AGREEMENT, ANY OTHER DEBT DOCUMENTS, OR TO ANY OTHER DOCUMENTS OR AGREEMENTS RELATING TO THIS TRANSACTION OR ANY RELATED TRANSACTION. THIS AGREEMENT MAY BE FILED AS A WRITTEN CONSENT TO A TRIAL BY THE COURT.

(h)

Mitigation. In the event that Borrower shall have paid to Lender the liquidated damages referred to in Clause 8(b) above, and Borrower shall have previously returned the Collateral to Lender in accordance with Clause 8(c) above, then Lender shall pay to Borrower, promptly after receipt thereof, all sale or rental proceeds received from any sale or re-letting of the Collateral during the balance of the Loan term (after deduction of all un-reimbursed damages, costs and expenses incurred by Lender as a result of the Event of Default; or other sums due Lender by Borrower under the Loan), said amount never to exceed the amount of the liquidated damages paid by Borrower. Lender shall use commercially reasonable efforts to sell, re-lease or otherwise use or dispose of the Collateral in mitigation of damages to the extent required by law (however, Lender shall not be obligated to give preference to the sale, lease or other disposition of the Collateral over the sale, lease or other disposition of similar equipment owned or leased by Lender).

9. MISCELLANEOUS.

(a)

Assignment. This Agreement, any Loan Schedule and/or any of the other Debt Documents may be assigned, in whole or in part, by Lender without notice to Borrower, and Borrower agrees not to assert against any such assignee, or assignee’s assigns, any defense, set-off, recoupment claim or counterclaim which Borrower has or may at any time have against Lender for any reason whatsoever. Borrower agrees that if Borrower receives written notice of an assignment from Lender, Borrower will pay all amounts payable under any assigned Debt Documents to such assignee or as instructed by Lender. Borrower also agrees to confirm in writing receipt of the notice of assignment as may be reasonably requested by Lender or assignee in form substantially similar to the form set forth in Schedule G attached hereto.

All notices to be given in connection with this Agreement shall be in writing, shall be addressed to the parties at their respective addresses set forth in this Agreement (unless and until a different address may be specified in a written notice to the other party), and shall be deemed given (i) on the date of receipt if delivered in hand or by facsimile or e-mail transmission, (ii) on the next business day after being sent by express mail, and (iii) on the fourth business day after being sent by regular, registered or certified mail. As used herein, the term “business day” shall mean and include any day other than Saturdays, Sundays, or other days on which commercial banks in San Francisco, California are required or authorized to be closed.

This Agreement shall be binding, jointly and severally, upon all parties described as the “Borrower” and their respective heirs, executors, representatives, successors and assigns, and shall inure to the benefit of Lender, its successors and assigns.

(d)

Entire Agreement. This Agreement and the Debt Documents constitute the entire agreement between the parties with respect to the subject matter of this Agreement and supersede all prior understandings (whether written, verbal or implied) with respect to such subject matter. THIS AGREEMENT AND THE DEBT DOCUMENTS SHALL NOT BE CHANGED OR TERMINATED ORALLY OR BY COURSE OF CONDUCT, BUT ONLY BY A WRITING SIGNED BY BOTH PARTIES. Section headings contained in this Agreement have been included for convenience only, and shall not affect the construction or interpretation of this Agreement.

(e)

Termination of Agreement and Security Interests. This Agreement shall continue in full force and effect until all of the Indebtedness has been paid in full to Lender or its assignee at which time this Agreement and all security interests granted hereby shall terminate, provided, that Borrower’s indemnity obligations set forth in Section 7(c) shall survive until all applicable statute of limitations periods with respect to actions that may be brought against Lender have run. This Agreement shall automatically be reinstated if Lender is ever required to return or restore the payment of all or any portion of the Indebtedness (all as though such payment had never been made).

(f)

CHOICE OF LAW. BORROWER AGREES THAT LENDER AND/OR ITS SUCCESSORS AND ASSIGNS SHALL HAVE THE OPTION BY WHICH STATE LAWS THIS AGREEMENT SHALL BE GOVERNED AND CONSTRUED AND SHALL SELECT EITHER: (A) THE LAWS OF THE STATE OF CALIFORNIA; OR (B) IF COLLATERAL HAS BEEN PLEDGED TO SECURE THE LIABILITIES, THEN BY THE LAWS OF THE STATE OR STATES WHERE THE COLLATERAL IS LOCATED, AT LENDER’S OPTION. THIS CHOICE OF STATE LAWS IS EXCLUSIVE TO THE LENDER. BORROWER SHALL NOT HAVE ANY OPTION TO CHOOSE THE LAWS BY WHICH THIS AGREEMENT SHALL BE GOVERNED. BORROWER ACKNOWLEDGES THAT THIS AGREEMENT IS BEING SIGNED BY THE LENDER IN PARTIAL CONSIDERATION OF LENDER’S RIGHT TO ENFORCE IN THE JURISDICTION STATED ABOVE. BORROWER CONSENTS TO JURISDICTION IN THE STATE OF CALIFORNIA OR THE STATE IN WHICH ANY COLLATERAL IS LOCATED AND VENUE IN ANY FEDERAL OR STATE COURT IN THE STATE OF CALIFORNIA OR THE STATE IN WHICH COLLATERAL IS LOCATED FOR SUCH PURPOSES AND WAIVES ANY AND ALL RIGHTS TO CONTEST SAID JURISDICTION AND VENUE AND ANY OBJECTION THAT SAID COUNTY IS NOT CONVENIENT. BORROWER WAIVES ANY RIGHTS TO COMMENCE ANY ACTION AGAINST LENDER IN ANY JURISDICTION EXCEPT THE STATE OF CALIFORNIA, OR IF LENDER CHOOSES TO LITIGATE IN A STATE WHERE COLLATERAL IS LOCATED THEN IN SUCH COUNTY AND STATE.

(g)

Limitation of Liability. The Lender shall not, under any circumstances, be liable for any error or omission or delay of any kind occurring in the settlement, collection or payment of any Receivables or any instrument received in payment thereof or for any damage resulting therefrom. The Lender is authorized to accept the return of the goods represented by any of the Receivables, without notice to or consent by the Borrower, or without discharging or in any manner affecting the Indebtedness.

(h)

Notification to Account Debtors. The Lender shall have the right at any time after the occurrence and during the continuation of an Event of Default to notify any Account Debtor of the Lender’s security interest in the Receivables and to require payments to be made directly to the Lender. To facilitate direct collection, the Borrower hereby appoints the Lender and any officer or employee of the Lender, as the Lender may from time to time designate, after the occurrence and during the
