Note to Lender. Lender shall fund the Term Loan Advance in the manner requested by the Advance Request provided that each of the conditions precedent to such Term Loan Advance is satisfied as of the requested Advance Date.

 (c) Interest. The principal balance of each Term Loan Advance shall bear
interest thereon from such Advance Date, calculated as of such Advance Date, at the Term Loan Interest Rate based on a year consisting of 360 days, with interest computed daily based on the actual number of days elapsed. The Term Loan Interest Rate

and regardless of any counterclaim or defense. Lender will initiate debit entries to the Borrower’s account as authorized on the ACH Authorization on each payment date of all periodic obligations payable to Lender under each Term Note or Term
Advance. 
 2.2 Maximum Interest. Notwithstanding any provision in this Agreement, the Notes, or any other Loan Document, it is
the parties’ intent not to contract for, charge or receive interest at a rate that is greater than the maximum rate permissible by law that a court of competent jurisdiction shall deem applicable hereto (which under the laws of the State of
California shall be deemed to be the laws relating to permissible rates of interest on commercial loans) (the “Maximum Rate”). If a court of competent jurisdiction shall finally determine that Borrower has actually paid to Lender an amount
of interest in excess of the amount that would have been payable if all of the Secured Obligations had at all times borne interest at the Maximum Rate, then such excess interest actually paid by Borrower shall be applied as follows: first, to the
payment of principal outstanding on the Notes; second, after all principal is repaid, to the payment of Lender’s accrued interest, costs, expenses, professional fees and any other Secured Obligations; and third, after all Secured Obligations
are repaid, the excess (if any) shall be refunded to Borrower. 
 2.3 Default Interest. In the event any payment is not paid on
the scheduled payment date, subject to applicable grace periods, an amount equal to two percent (2%) of the past due amount shall be payable on demand. In addition, upon the occurrence and during the continuation of an Event of Default
hereunder, all Secured Obligations, including principal, interest, compounded interest, and professional fees, shall bear interest at a rate per annum equal to the rate set forth in Section 2.1(c) plus five percent (5%) per annum. In the
event any interest is not paid when due hereunder, delinquent interest shall be added to principal and shall bear interest on interest, compounded at the rate set forth in Section 2.1(c) or Section 2.3, as applicable. 
  

 11 








 2.4 Prepayment. At its option upon at least 7 days prior notice to Lender, Borrower may
prepay all, but not less than all, of the outstanding Advances by paying the entire principal balance, all accrued and unpaid interest, together with a prepayment charge equal to the following percentage of the principal Advance amount being
prepaid: if such Advance amounts are prepaid in any of the (i) first six (6) months following the Closing Date, 3%; (ii) after six (6) months but prior to eighteen (18) months, 2%; (iii) after eighteen (18) months
but prior to thirty (30) months, 1% (each, a “Prepayment Charge”); provided, that no Prepayment Charge is payable and due thereafter. Borrower agrees that the Prepayment Charge is a reasonable calculation of Lender’s lost
profits in view of the difficulties and impracticality of determining actual damages resulting from an early repayment of the Advances. The outstanding amount of all principal and accrued interest and unpaid interest will become immediately due and
payable without premium or penalty at Lender’s option upon a Change in Control. 
 2.5 End of Term Charge. On the earliest
to occur of (i) the Term Loan Maturity Date, (ii) the date that Borrower prepays all of the outstanding Secured Obligations, or (iii) the date that the Secured Obligations become due and payable, Borrower shall pay Lender a charge
equal to 5.95% of the aggregate initial principal amount of the Term Loan Advances drawn by Borrower.

capital stock of any Subsidiary that is incorporated or organized in a jurisdiction other than the United States or any state or territory thereof or the District of Columbia if to do so could reasonably be expected to cause Borrower adverse tax
consequences under Internal Revenue Code Section 956 (or any successor statute); (B) Intellectual Property (other than Rights to Payment); (C) any Equipment or Proceeds thereof that is subject to a Lien that is otherwise permitted by
clause (vii) of the definition of “Permitted Lien” hereunder if inclusion of such Equipment would constitute a breach by Borrower of its agreement

  

 12 








 
with a third party equipment lessor or lender, provided, that upon the release of any such Lien such Equipment shall be deemed to be Collateral hereunder and shall be subject to the security
interest granted herein; (D) cash held in money market account no. 1892029636 at Comerica in an amount not to exceed $552,000 plus accrued interest to secure certain letters of credit; and (E) cash subject to a Lien permitted by clause
(xiv) of the definition of “Permitted Liens”. Notwithstanding the foregoing, if a judicial authority (including a U.S. Bankruptcy Court) holds that a security interest in the underlying Intellectual Property is necessary to have a
security interest in the Rights to Payment, and the existence of such security interest would not otherwise violate or breach any provision in any applicable agreement or contract that is enforceable under the UCC with respect to the applicable
Intellectual Property, then the Collateral shall automatically, and effective as of the Closing Date, include the Intellectual Property to the extent necessary to permit perfection of Lender’s security interest in the Rights to Payment. Lender
hereby agrees to provide Borrower, at Borrower’s expense, with any release, partial termination or other documents reasonably requested by Borrower to reflect or confirm that the Collateral does not include any property excluded from the
definition thereof.

 5.1 Corporate Status. Borrower is a corporation duly organized, legally existing and in good standing under the laws of the State of Delaware, and is duly qualified as a foreign corporation in all

names (if any), locations, place of formation, tax identification number, organizational identification number and other information are correctly set forth in Exhibit C. 
  


 14 








 5.2 Collateral. Borrower owns the Collateral and the Intellectual Property, free of all
Liens, except for Permitted Liens and JV Restrictions. Borrower has the power and authority to grant to Lender a Lien in the Collateral as security for the Secured Obligations . 
 5.3 Consents. Borrower’s execution, delivery and performance of the Notes, this Agreement and all other Loan Documents, and
Borrower’s execution of the Warrant, (i) have been duly authorized by all necessary corporate action of Borrower, (ii) will not result in the creation or imposition of any Lien upon the Collateral, other than Permitted Liens and the
Liens created by this Agreement and the other Loan Documents, (iii) do not violate any provisions of Borrower’s Certificate of Incorporation, bylaws, or any material law, regulation, order, injunction, judgment, decree or writ to which
Borrower is subject and (iv) do not violate any material contract or agreement or require the consent or approval of any other Person that has not been obtained. The individual or individuals executing the Loan Documents and the Warrant are
duly authorized to do so. 
 5.4 Material Adverse Effect. No event that has had or could reasonably be expected to have a
Material Adverse Effect has occurred and is continuing. Borrower is not aware of any event likely to occur that is reasonably expected to result in a Material Adverse Effect. 
 5.5 Actions Before Governmental Authorities. Except as described on Schedule 5.5, there are no actions, suits or proceedings at law or in
equity or by or before any governmental authority now pending or, to the knowledge of Borrower, threatened in writing against or affecting Borrower or its property (i) which involve any Loan Document or (ii) as to which there is a
reasonable possibility of an adverse determination and which, if adversely determined, would reasonably be expected to result in a Material Adverse Effect. 
 5.6 Laws. Borrower is not in violation of any law, rule or regulation, or in default with respect to any judgment, writ, injunction or decree of any governmental authority, where such violation or default
is reasonably expected to result in a Material Adverse Effect. Borrower is not in default in any manner under any provision of any agreement or instrument evidencing indebtedness, or any other material agreement to which it is a party or by which it
is bound and for which such default would reasonably be expected to result in an Material Adverse Effect. 
 5.7 Information
Correct and Current. No information, report, Advance Request, financial statement, exhibit or schedule furnished, by or on behalf of Borrower to Lender in connection with any Loan Document or included therein or delivered pursuant thereto contained,
contains or will contain any material misstatement of fact or omitted, omits or will omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were, are or will be made, not
misleading in any material respect at the time such statement was made or deemed made. Additionally, any and all financial or business projections provided by Borrower to Lender shall be provided in good faith based upon assumptions believed to be
reasonable at the time. 
  

 15 








 5.8 Tax Matters. (a) Borrower has filed all federal, state and local tax returns that
it is required to file, (b) Borrower has duly paid or fully reserved in accordance with GAAP for all taxes or installments thereof (including any interest or penalties) as and when due, which have or may become due pursuant to such returns, and
(c) Borrower has paid or fully reserved in accordance with GAAP for any tax assessment received by Borrower for the three (3) years preceding the Closing Date, if any (including any taxes being contested in good faith and by appropriate
proceedings). 
 5.9 Intellectual Property Claims. Borrower is the sole owner of, or otherwise has the right to use, the
Intellectual Property. Except as described on Schedule 5.9, to the Borrower’s knowledge, (i) each of the material 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 that any of the foregoing would not reasonably
be expected to cause a Material Adverse Effect. Exhibit D is a true, correct and complete list of each of Borrower’s Patents, registered Trademarks, registered Copyrights, and material agreements under which Borrower licenses Intellectual
Property from third parties (other than shrink-wrap software licenses and other licenses which if terminated could not reasonably be expected to result a Material Adverse Effect), together with application or registration numbers, as applicable,
owned by Borrower or any Subsidiary, in each case as of the Closing Date and each other date required by Section 7.15. Borrower is not in material breach of, nor has Borrower failed to perform any material obligations under, any of the
foregoing contracts, licenses or agreements and, to Borrower’s knowledge, no third party to any such contract, license or agreement is in material breach thereof or has failed to perform any material obligations thereunder. 
 5.10 Intellectual Property. Except as described on Schedule 5.10, Borrower has, or in the case of any proposed business, will have, all
material rights with respect to Intellectual Property necessary in the operation or conduct of Borrower’s business as currently conducted and proposed to be conducted by Borrower. Without limiting the generality of the foregoing, and in the
case of Licenses, except for restrictions that are unenforceable under Division 9 of the UCC, Borrower has the right, to the extent required to operate Borrower’s business, to freely transfer, license or assign Intellectual Property without
condition, restriction or payment of any kind (other than license payments in the Ordinary Course of Business and JV Restrictions) to any third party, and Borrower owns or has the right to use, pursuant to valid licenses, all software development
tools, library functions, compilers and all other third-party software and other items that are material to the Borrower’s business and used in the design, development, promotion, sale, license, manufacture, import, export, use or distribution
of Borrower Products. 
 5.11 Borrower Products. Except as described on Schedule 5.11, no Intellectual Property owned by
Borrower or Borrower Product has been or is subject to any actual or, to the knowledge of Borrower, threatened litigation, proceeding (including any proceeding in the United States Patent and Trademark Office or any corresponding foreign office or
agency) or outstanding decree,

  

 16 








 
order, judgment, settlement agreement or stipulation that restricts in any manner Borrower’s use, transfer or licensing thereof or that may affect the validity, use or enforceability thereof
except to the extent any of the foregoing would not reasonably be expected to cause a Material Adverse Effect. There is no decree, order, judgment, agreement, stipulation, arbitral award or other provision entered into in connection with any
litigation or proceeding that obligates Borrower to grant licenses or ownership interest in any future Intellectual Property related to the operation or conduct of the business of Borrower or Borrower Products. Borrower has not received any written
notice or claim, or, to the knowledge of Borrower, oral notice or claim, challenging or questioning Borrower’s ownership in any Intellectual Property (or written notice of any claim challenging or questioning the ownership in any licensed
Intellectual Property of the owner thereof) or suggesting that any third party has any claim of legal or beneficial ownership with respect thereto nor, to Borrower’s knowledge, is there a reasonable basis for any such claim except to the extent
any of the foregoing would not reasonably be expected to cause a Material Adverse Effect. To the knowledge of Borrower, neither Borrower’s use of its Intellectual Property nor the production and sale of Borrower Products infringes the
Intellectual Property or other rights of others in a manner as to be reasonably expected to cause a Material Adverse Effect. 
 5.12 Financial Accounts. Exhibit E, as may be updated by the Borrower in a written notice provided to Lender after the Closing Date, is a true, correct and complete list of (a) all banks and other financial institutions at which
Borrower or any Subsidiary maintains Deposit Accounts and (b) all institutions at which Borrower or any Subsidiary maintains an account holding Investment Property, and such exhibit correctly identifies the name, address and telephone number of
each bank or other institution, the name in which the account is held, a description of the purpose of the account, and the complete account number therefor. 
 5.13 Employee Loans. Except as permitted by Section 7.8, Borrower has no outstanding loans to any employee, officer or director of the Borrower nor has Borrower guaranteed the payment of any loan
made to an employee, officer or director of the Borrower by a third party. 
 5.14 Capitalization and Subsidiaries.
Borrower’s capitalization as of the Closing Date is set forth on Schedule 5.14 annexed hereto. Borrower does not own any stock, partnership interest or other equity securities of any Person, except for Permitted Investments. Attached as
Schedule 1D, as may be updated by Borrower in a written notice provided after the Closing Date, is a true, correct and complete list of each Subsidiary. 
 SECTION 6. INSURANCE; INDEMNIFICATION 
 6.1 Coverage. So long as
there are any Secured Obligations outstanding or Lender has any commitment to make Advances, Borrower shall cause to be carried and maintained commercial general liability insurance, on an occurrence form, against risks customarily insured against
in Borrower’s line of business. Such risks shall include the risks of bodily injury, including death,

  

 17 








 
property damage, personal injury, advertising injury, and contractual liability per the terms of the indemnification agreement found in Section 6.3. Borrower must maintain a minimum of
$2,000,000 of commercial general liability insurance for each occurrence. Borrower has and agrees to maintain a minimum of $2,000,000 of directors and officers’ insurance for each occurrence and $5,000,000 in the aggregate. So long as there are
any Secured Obligations outstanding, Borrower shall also cause to be carried and maintained insurance upon the Collateral to the extent a specific type of Collateral is customarily insured against in Borrower’s business and industry, insuring
against all risks of physical loss or damage howsoever caused, in an amount not less than the full replacement cost of such Collateral, provided that such insurance may be subject to standard exceptions and deductibles. Borrower shall also carry and
maintain a fidelity insurance policy in an amount not less than $300,000. 
 6.2 Certificates. Borrower shall deliver to Lender
certificates of insurance that evidence Borrower’s compliance with its insurance obligations in Section 6.1 and the obligations contained in this Section 6.2. Borrower’s insurance certificate shall state Lender is an additional
insured for commercial general liability, an additional insured and a loss payee for all risk property damage insurance, subject to the insurer’s approval, a loss payee for fidelity insurance, and a loss payee for property insurance and
additional insured for liability insurance for any future insurance that Borrower may acquire from such insurer. Attached to the certificates of insurance will be additional insured endorsements for liability and lender’s loss payable
endorsements for all risk property damage insurance and fidelity. All certificates of insurance will provide for a minimum of thirty (30) days advance written notice to Lender of cancellation or any other change adverse to Lender’s
interests, except with respect to cancellation due to non-payment in which case ten (10) days advance written notice is sufficient. Any failure of Lender to scrutinize such insurance certificates for compliance is not a waiver of any of
Lender’s rights, all of which are reserved. 
 6.3 Indemnity. Borrower agrees to indemnify and hold Lender and its
officers, directors, employees, agents, attorneys, representatives and shareholders harmless from and against any and all claims, costs, expenses, damages and liabilities (including such claims, costs, expenses, damages and liabilities based on
liability in tort, including strict liability in tort), including reasonable attorneys’ fees and disbursements and other reasonable costs of investigation or defense (including those incurred upon any appeal), that may be instituted or asserted
against or incurred by Lender or any such Person as the result of credit having been extended, suspended or terminated under this Agreement and the other Loan Documents or the administration of such credit, or in connection with or arising out of
the transactions contemplated hereunder and thereunder, or any actions or failures to act in connection therewith, or arising out of the disposition or utilization of the Collateral, excluding in all cases claims resulting solely from Lender’s
gross negligence or willful misconduct. Borrower agrees to pay, and to save Lender harmless from, any and all liabilities with respect to, or resulting from any delay in paying, any and all excise, sales or other similar taxes (excluding taxes
imposed on or measured by the net income of Lender) that may be payable or determined to be payable with respect to any of the Collateral or this Agreement;

  

 18 








 
provided, however, that, (i) with respect to such liabilities imposed originally and independently on Lender, Lender shall notify Borrower of any such liabilities within 180
days of the initial date Lender has actual knowledge, or should have had knowledge, of its direct exposure to such liabilities and, (ii) with respect to all other such liabilities not described in subsection (i), Lender shall notify
Borrower of any such liabilities within 180 days of the initial date Lender has actual knowledge of its direct exposure to such liabilities.

 7.2 Management Rights. Borrower shall permit any representative that Lender authorizes, including its attorneys and accountants, to inspect
the Collateral and examine and make copies and abstracts of the books of account and records of Borrower at reasonable times and upon reasonable notice during normal business hours (but in any event no more than twice in any 12 month

  

 20 








 
period unless an Event of Default has occurred and is continuing). In addition, any such representative shall have the right to meet with management and officers of Borrower to discuss such books
of account and records. In addition, Lender shall be entitled at reasonable times and intervals to consult with and advise the management and officers of Borrower concerning significant business issues affecting Borrower. Such consultations shall
not unreasonably interfere with Borrower’s business operations. The parties intend that the rights granted Lender shall constitute “management rights” within the meaning of 29 C.F.R Section 2510.3-101(d)(3)(ii), but that any
advice, recommendations or participation by Lender with respect to any business issues shall not be deemed to give Lender, nor be deemed an exercise by Lender of, control over Borrower’s management or policies. 
 7.3 Further Assurances. Borrower shall from time to time execute, deliver and file, alone or with Lender, any financing statements, security
agreements, collateral assignments, notices, control agreements, or other documents necessary to perfect or give the highest priority to Lender’s Lien on the Collateral (subject to Permitted Liens). Borrower shall from time to time procure any
instruments or documents as may be reasonably requested by Lender, and take all further action that may be necessary or that Lender may reasonably request, to perfect and protect the Liens granted hereby and thereby. In addition, and for such
purposes only, Borrower hereby authorizes Lender to execute and deliver on behalf of Borrower and to file such financing statements, collateral assignments, notices, control agreements, security agreements and other documents without the signature
of Borrower either in Lender’s name or in the name of Lender as agent and attorney-in-fact for Borrower. Borrower shall, in its reasonable business judgment, protect and defend Borrower’s title to the Collateral and Lender’s Lien
thereon against all Persons claiming any interest adverse to Borrower or Lender other than Permitted Liens. 
 7.4 Compromise of
Agreements. Without Lender’s prior written consent, Borrower shall not, nor shall it allow any of its Subsidiaries to, (a) grant any material extension of the time of payment of any of the Account receivable or General Intangibles other
than extensions in the Ordinary Course of Business which are consistent with past practices, (b) to any material extent, compromise, compound or settle the same for less than the full amount thereof other than in the Ordinary Course of Business
and consistent with past practices, (c) release, wholly or partly, any Person liable for the payment thereof other than in the Ordinary Course of Business and consistent with past practices, or (d) allow any credit or discount whatsoever
thereon other than trade discounts granted by Borrower or such Subsidiary in the Ordinary Course of Business of Borrower or such Subsidiary which are consistent with past practices. 
 7.5 Indebtedness. Borrower shall not create, incur, assume, guarantee or be or remain liable with respect to any Indebtedness, or permit any
Subsidiary so to do, other than Permitted Indebtedness, or prepay any Indebtedness or take any actions which impose on Borrower an obligation to prepay any Indebtedness, except Indebtedness to Lender in accordance herewith or for the conversion of
Indebtedness into equity securities and the payment of cash in lieu of fractional shares in connection with such conversion. 
  

 21 








 7.6 Collateral. Borrower shall at all times keep the Collateral, the Intellectual Property
and all other property and assets used in Borrower’s business or in which Borrower now or hereafter holds any interest free and clear from any legal process or Liens whatsoever (except for Permitted Liens), and shall give Lender prompt written
notice of any legal process affecting the Collateral, the Intellectual Property, such other property and assets, or any Liens thereon. Borrower shall cause its Subsidiaries to protect and defend such Subsidiary’s title to its assets from and
against all Persons claiming any interest adverse to such Subsidiary, and Borrower shall cause its Subsidiaries at all times to keep such Subsidiary’s property and assets free and clear from any legal process or Liens whatsoever (except for
Permitted Liens), and shall give Lender prompt written notice of any legal process affecting such Subsidiary’s assets. Borrower shall not permit the inclusion in any contract to which it or a Subsidiary becomes a party of any provisions that
restrict or invalidate the granting of a security interest in any of Borrower’s or such Subsidiary’s property and assets other than with respect to contractual restrictions on Intellectual Property entered into with third party strategic
collaboraters that are not financial institutions in the Ordinary Course of Business (“JV Restrictions”). 
 7.7
Investments. Borrower shall not directly or indirectly acquire or own, or make any Investment in or to any Person, or permit any of its Subsidiaries so to do, other than Permitted Investments. 
 7.8 Distributions. Without the prior written consent of the Lender, Borrower shall not, and shall not allow any Subsidiary to,
(a) repurchase or redeem any class of stock or other equity interest other than pursuant to employee, director or consultant repurchase plans or other similar agreements, provided, however, in each case the repurchase or redemption price does
not exceed the original consideration paid for such stock or equity interest by more than $250,000 in the aggregate in any fiscal year, or (b) declare or pay any cash dividend or make a cash distribution on any class of stock or other equity
interest, except that a Subsidiary may pay dividends or make distributions to Borrower, or (c) lend money to any employees, officers or directors or guarantee the payment of any such loans granted by a third party in excess of $250,000 in the
aggregate in any fiscal year or (d) waive, release or forgive any indebtedness owed by any employees, officers or directors in excess of $250,000 in the aggregate. 
 7.9 Transfers. Except for Permitted Transfers, Borrower shall not voluntarily or involuntarily transfer, sell, lease, license, lend or in any other manner convey any equitable, beneficial or legal
interest in any material portion of their assets. 
 7.10 Mergers or Acquisitions. Without Lender’s prior written consent,
not to be unreasonably withheld, Borrower shall not merge or consolidate, or permit any of its Subsidiaries to merge or consolidate, with or into any other business organization (other than mergers or consolidations of a Subsidiary into another
Subsidiary or into Borrower), or acquire, or permit any of its Subsidiaries to acquire, all or substantially all of the capital stock or property of another Person; provided, that Borrower may make (i) acquisitions utilizing cash as
consideration that constitute Permitted Investments and (ii) acquisitions utilizing Borrower’s stock as consideration that do not result in a Change of Control. 
  


 22 








 7.11 Taxes. Borrower and its Subsidiaries shall pay when due all taxes, fees or other
charges of any nature whatsoever (together with any related interest or penalties) now or hereafter imposed or assessed against Borrower, Lender or the Collateral or upon Borrower’s ownership, possession, use, operation or disposition thereof
or upon Borrower’s rents, receipts or earnings arising therefrom. Borrower shall file on or before the due date therefor all personal property tax returns in respect of the Collateral. Notwithstanding the foregoing in this Section 7.11,
Borrower may contest, in good faith and by appropriate proceedings, taxes for which Borrower maintains adequate reserves therefor in accordance with GAAP. 
 7.12 Corporate Changes. Neither Borrower nor any Subsidiary shall change its corporate name, legal form or jurisdiction of formation without twenty (20) days’ prior written notice to Lender.
Neither Borrower nor any Subsidiary shall relocate its chief executive office or its principal place of business unless: (i) it has provided prior written notice to Lender; and (ii) such relocation shall be within the continental United
States. Neither Borrower nor any Subsidiary shall relocate any item of Collateral (other than (v) relocations of clinical trial supplies in the Ordinary Course Business, (w) Permitted Transfers, (x) sales of Inventory in the Ordinary
Course of Business, (y) relocations of Equipment having an aggregate value of up to $250,000 in any fiscal year, and (z) relocations of Collateral from a location described on Exhibit C to another location described on Exhibit C) unless
(i) it has provided prompt written notice to Lender, (ii) such relocation is within the continental United States and, (iii) if such relocation is to a third party bailee, it has used commercially reasonable efforts to obtain a bailee
agreement in form and substance reasonably acceptable to Lender, provided, that it shall deliver such a bailee agreement for any such relocation of assets in excess of $1,000,000. 
 7.13 Deposit Accounts. Subject to the remainder of this Section 7.13, neither Borrower nor any Subsidiary shall maintain any Deposit
Accounts, or accounts holding Investment Property, except with respect to which Lender has an Account Control Agreement. All Deposit Accounts and accounts holding Investment Property maintained by Borrower at Comerica on the Closing Date shall
continue to be maintained at Comerica, unless closed with the prior written consent of Comerica. Borrower agrees to maintain a minimum of $6,000,000 in Cash in a money market or securities account with Comerica or one of its Affiliates;
provided, however, that if Borrower’s total Cash balances are less than $6,000,000, Borrower may maintain less than $6,000,000 with Comerica provided that, it shall maintain all of its cash with Comerica or one of its
Affiliates. For avoidance of doubt, this Section 7.13 is not a minimum cash covenant. Borrower shall deliver, or cause to be delivered, monthly statements evidencing the holdings of all Deposit Accounts and accounts holding Investment Property
maintained by Borrower at financial institutions other than Comerica. 
  

 23 








 7.14 Subsidiaries. Borrower shall notify Lender of each Subsidiary formed subsequent to the
Closing Date and, within 15 days of formation, shall cause any such Subsidiary to execute and deliver to Lender a Joinder Agreement unless to do so could be expected to cause Borrower adverse tax consequences under Internal Revenue Code
Section 956 (or any successor statute). 
 7.15 Intellectual Property. Borrower shall update the Intellectual Property
information listed on Exhibit D within 30 days of each quarter end. 
 7.16 GECC Covenant Indebtedness. Borrower shall not
directly or indirectly, amend, modify, alter, increase, or change any of the terms or conditions of the GECC Security Agreement, or any agreement, instrument, document, or other writing evidencing or concerning the GECC Covenant Indebtedness, except
to the extent that such amendment, modification, alteration, increase, or change (i) was made with the prior written consent of Lender or (ii) is of a non-material and administrative nature. On or before June 20, 2008, Borrower shall

 SECTION 10. REMEDIES 
 10.1 General. Upon and during the continuance
of any one or more Events of Default, (i) Lender may, at its option, accelerate and demand payment of all or any part of the Secured Obligations together with a Prepayment Charge and declare them to be immediately due and payable (provided,
that upon the occurrence of an Event of Default of the type described in Section 9.6, the Notes and all of the Secured Obligations shall automatically be accelerated and made due and payable, in each case without any further notice or act), and
(ii) Lender may notify any of Borrower’s account debtors to make payment directly to Lender, compromise the amount of any such account on Borrower’s behalf and endorse Lender’s name without recourse on any such payment for
deposit directly to Lender’s account. Lender may exercise all rights and remedies with respect to the Collateral under the Loan Documents or otherwise available to it under the UCC and other applicable law, including the right to release, hold,
sell, lease, liquidate, collect, realize upon, or otherwise dispose of all or any part of the Collateral and the right to occupy, utilize, process and commingle the Collateral. All Lender’s rights and remedies shall be cumulative and not
exclusive. 
 10.2 Collection; Foreclosure. Upon the occurrence and during the continuance of any Event of Default, Lender may,
at any time or from time to time, apply, collect, liquidate, sell in one or more sales, lease or otherwise dispose of, any or all of the Collateral, in its then condition or following any commercially reasonable preparation or processing, in such
order as Lender may elect. Any such sale may be made either at public or private sale at its place of business or elsewhere. Borrower agrees that any such public or private sale may occur upon ten (10) calendar days’ prior written notice
to Borrower. Lender may require Borrower to assemble the Collateral and make it available to Lender at a place designated by Lender that is reasonably convenient to Lender and Borrower. The proceeds of any sale, disposition or other realization upon
all or any part of the Collateral shall be applied by Lender in the following order of priorities: 
 First, to Lender in an
amount sufficient to pay in full Lender’s costs and professionals’ and advisors’ fees and expenses as described in Section 11.11; 
  

 26 








 Second, to Lender in an amount equal to the then unpaid amount of the Secured Obligations
(including principal, interest, and the Default Rate interest), in such order and priority as Lender may choose in its sole discretion; and 
 Finally, after the full and final payment in Cash of all of the Secured Obligations, to any creditor holding a junior Lien on the Collateral, or to Borrower or its representatives or as a court of
competent jurisdiction may direct. 
 Lender shall be deemed to have acted reasonably in the custody, preservation and disposition of any of the
Collateral if it complies with the obligations of a secured party under the UCC. 
 10.3 No Waiver. Lender shall be under no
obligation to marshal any of the Collateral for the benefit of Borrower or any other Person, and Borrower expressly waives all rights, if any, to require Lender to marshal any Collateral. 
 10.4 Cumulative Remedies. The rights, powers and remedies of Lender hereunder shall be in addition to all rights, powers and remedies given
by statute or rule of law and are cumulative. The exercise of any one or more of the rights, powers and remedies provided herein shall not be construed as a waiver of or election of remedies with respect to any other rights, powers and remedies of
Lender. 
 SECTION 11. MISCELLANEOUS 
 11.1 Severability. Whenever possible, each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement shall
be prohibited by or invalid under such law, such provision shall be ineffective only to the extent and duration of such prohibition or invalidity, without invalidating the remainder of such provision or the remaining provisions of this Agreement.

 11.2 Notice. Except as otherwise provided herein, any notice, demand, request, consent, approval, declaration, service of
process or other communication (including the delivery of Financial Statements) that is required, contemplated, or permitted under the Loan Documents or with respect to the subject matter hereof shall be in writing, and shall be deemed to have been

 11.3 Entire Agreement; Amendments. This Agreement, the Notes, and the other Loan Documents
constitute the entire agreement and understanding of the parties hereto in respect of the subject matter hereof and thereof, and supersede and replace in their entirety any prior proposals, term sheets, letters, negotiations or other documents or
agreements, whether written or oral, with respect to the subject matter hereof or thereof (including Lender’s revised proposal letter dated February 4, 2008 and the Prior Agreement). None of the terms of this Agreement, the Notes or any of
the other Loan Documents may be amended except by an instrument executed by each of the parties hereto. 
 11.4 No Strict
Construction. The parties hereto have participated jointly in the negotiation and drafting of this Agreement. In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the
parties hereto and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provisions of this Agreement. 
 11.5 No Waiver. The powers conferred upon Lender by this Agreement are solely to protect its rights hereunder, except those rights granted to Hercules pursuant to Section 8 of this Agreement, and
under the other Loan Documents and its interest in the Collateral and shall not impose any duty upon Lender to exercise any such powers. No omission or delay by Lender at any time to enforce any right or remedy reserved to it, or to require
performance of any of the terms, covenants or provisions hereof by Borrower at any time designated, shall be a waiver of any such right or remedy to which Lender is entitled, nor shall it in any way affect the right of Lender to enforce such
provisions thereafter. 
 11.6 Survival. All agreements, representations and warranties contained in this Agreement, the Notes
and the other Loan Documents or in any document delivered pursuant hereto or thereto shall be for the benefit of Lender and shall survive the execution and delivery of this Agreement and the expiration or other termination of this Agreement.

 11.7 Successors and Assigns. The provisions of this Agreement and the other Loan Documents shall inure to the benefit of and
be binding on Borrower and its permitted assigns (if any). Borrower shall not assign its obligations under this Agreement, the Notes or any of the other Loan Documents without Lender’s express prior written consent, and any such attempted
assignment shall be void and of no effect. Lender may assign, transfer, or endorse its rights hereunder and under the other Loan Documents without prior notice to Borrower, and all of such rights shall inure to the benefit of Lender’s
successors and assigns. 
 11.8 Governing Law. This Agreement, the Notes and the other Loan Documents have been negotiated and
delivered to Lender in the State of California, and shall have been accepted by Lender in the State of California. Payment to Lender by Borrower of the Secured Obligations is due in the State of California. This Agreement, the Notes and the other
Loan Documents shall be governed by, and construed and enforced in accordance with, the laws of the State of California, excluding conflict of laws principles that would cause the application of laws of any other jurisdiction. 
  

 29 








 11.9 Consent to Jurisdiction and Venue. All judicial proceedings (to the extent that the
reference requirement of Section 11.10 is not applicable) arising in or under or related to this Agreement, the Notes or any of the other Loan Documents may be brought in any state or federal court located in the State of California. By
execution and delivery of this Agreement, each party hereto generally and unconditionally: (a) consents to nonexclusive personal jurisdiction in Santa Clara County, State of California; (b) waives any objection as to jurisdiction or venue
in Santa Clara County, State of California; (c) agrees not to assert any defense based on lack of jurisdiction or venue in the aforesaid courts; and (d) irrevocably agrees to be bound by any judgment rendered thereby in connection with
this Agreement, the Notes or the other Loan Documents. Service of process on any party hereto in any action arising out of or relating to this Agreement shall be effective if given in accordance with the requirements for notice set forth in
Section 11.2, and shall be deemed effective and received as set forth in Section 11.2. Nothing herein shall affect the right to serve process in any other manner permitted by law or shall limit the right of either party to bring
proceedings in the courts of any other jurisdiction. 
 11.10 Mutual Waiver of Jury Trial / Judicial Reference. 
 (a) Because disputes arising in connection with complex financial transactions are most quickly and economically resolved by
an experienced and expert person and the parties wish applicable state and federal laws to apply (rather than arbitration rules), the parties desire that their disputes be resolved by a judge applying such applicable laws. EACH OF BORROWER AND
LENDER SPECIFICALLY WAIVES ANY RIGHT IT MAY HAVE TO TRIAL BY JURY OF ANY CAUSE OF ACTION, CLAIM, CROSS-CLAIM, COUNTERCLAIM, THIRD PARTY CLAIM OR ANY OTHER CLAIM (COLLECTIVELY, “CLAIMS”) ASSERTED BY BORROWER AGAINST LENDER OR ITS ASSIGNEE
OR BY LENDER OR ITS ASSIGNEE AGAINST BORROWER. This waiver extends to all such Claims, including Claims that involve Persons other than Borrower and Lender; Claims that arise out of or are in any way connected to the relationship between Borrower
and Lender; and any Claims for damages, breach of contract, tort, specific performance, or any equitable or legal relief of any kind, arising out of this Agreement, any other Loan Document. 
 (b) If the waiver of jury trial set forth in Section 11.10(a) is ineffective or unenforceable, the parties agree that
all Claims shall be resolved by reference to a private judge sitting without a jury, pursuant to Code of Civil Procedure Section 638, before a mutually acceptable referee or, if the parties cannot agree, a referee selected by the Presiding
Judge of the Santa Clara County, California. Such proceeding shall be conducted in Santa Clara County, California, with California rules of evidence and discovery applicable to such proceeding. 
 (c) In the event Claims are to be resolved by judicial reference, either party may seek from a court identified in
Section 11.9, any prejudgment order, writ or other relief and have such prejudgment order, writ or other relief enforced to the fullest extent permitted by law notwithstanding that all Claims are otherwise subject to resolution by judicial
reference. 
  

 30 








 11.11 Professional Fees. Borrower promises to pay Lender’s reasonable fees and expenses
necessary to finalize the loan documentation, including but not limited to reasonable attorneys fees, UCC searches, filing costs, and other reasonable miscellaneous expenses. In addition, Borrower promises to pay any and all reasonable
attorneys’ and other professionals’ fees and expenses incurred by Lender after the Closing Date in connection with or related to: (a) the Loan; (b) the administration, collection, or enforcement of the Loan; (c) the
amendment or modification of the Loan Documents; (d) any waiver, consent, release, or termination under the Loan Documents; (e) the protection, preservation, sale, lease, liquidation, or disposition of Collateral or the exercise of
remedies with respect to the Collateral; (f) any legal, litigation, administrative, arbitration, or out of court proceeding in connection with or related to Borrower or the Collateral, and any appeal or review thereof; and (g) any
bankruptcy, restructuring, reorganization, assignment for the benefit of creditors, workout, foreclosure, or other action related to Borrower, the Collateral, the Loan Documents, including representing Lender in any adversary proceeding or contested
matter commenced or continued by or on behalf of Borrower’s estate, and any appeal or review thereof. 
 11.12
Confidentiality. Lender acknowledges that certain items of Collateral and information provided to Lender by Borrower are confidential and proprietary information of Borrower (the “Confidential Information”) and agrees to exercise the same
degree of care that Lender exercises with respect to its own proprietary information of the same types to maintain the confidentially of any such Confidential Information received in connection with this Agreement. Lender agrees that any
Confidential Information it may obtain shall not be disclosed to any other person or entity in any manner whatsoever, in whole or in part, without the prior written consent of Borrower, except that Lender may disclose any such information:
(a) to its own directors, officers, employees, accountants, counsel and other professional advisors and to its affiliates if Lender in its sole discretion determines that any such party should have access to such information in connection with
such party’s responsibilities in connection with the Loan or this Agreement and, provided that such recipient of such Confidential Information either (i) agrees to be bound by the confidentiality provisions of this paragraph or
(ii) is otherwise subject to confidentiality restrictions that reasonably protect against the disclosure of Confidential Information; (b) if such information is generally available to the public; (c) if required in any report,
statement or testimony submitted to any governmental authority having jurisdiction over Lender; (d) if required in response to any summons or subpoena or in connection with any litigation, to the extent permitted or deemed advisable by
Lender’s counsel; (e) to comply with any legal requirement or law applicable to Lender; (f) to the extent reasonably necessary in connection with the exercise of any right or remedy under any Loan Document, including Lender’s
sale, lease, or other disposition of Collateral after default; (g) to any participant or assignee of Lender or any prospective participant or assignee; provided, that such participant or assignee or prospective participant or assignee agrees in
writing to be bound by this Section prior to disclosure; or (h) otherwise with the prior consent of Borrower; provided, that any disclosure made in violation of this Agreement shall not affect the obligations of Borrower or any of its
affiliates or any guarantor under this Agreement or the other Loan Documents. 
  

 31 








 11.13 Assignment of Rights. Borrower acknowledges and understands that Lender may sell and
assign all or part of its interest hereunder and under the Note(s) and Loan Documents to any person or entity other than a person or entity reasonably deemed by Lender to be a direct competitor of Borrower (an “Assignee”); provided,
that Hercules shall not sell or assign any rights pursuant to Section 8 of this Agreement without the consent of the Borrower. After such assignment the term “Lender” as used in the Loan Documents shall mean and include such Assignee,
and such Assignee shall be vested with all rights, powers and remedies of Lender hereunder with respect to the interest so assigned; but with respect to any such interest not so transferred, Lender shall retain all rights, powers and remedies hereby
given. No such assignment by Lender shall relieve Borrower of any of its obligations hereunder. Lender agrees that in the event of any transfer by it of the Note(s), it will endorse thereon a notation as to the portion of the principal of the
Note(s), which shall have been paid at the time of such transfer and as to the date to which interest shall have been last paid thereon. 
 11.14 Revival of Secured Obligations. This Agreement and the Loan Documents shall remain in full force and effect and continue to be effective if any petition is filed by or against Borrower for
liquidation or reorganization, if Borrower becomes insolvent or makes an assignment for the benefit of creditors, if a receiver or trustee is appointed for all or any significant part of Borrower’s assets, or if any payment or transfer of
Collateral is recovered from Lender. The Loan Documents and the Secured Obligations and Collateral security shall continue to be effective, or shall be revived or reinstated, as the case may be, if at any time payment and performance of the Secured
Obligations or any transfer of Collateral to Lender, or any part thereof is rescinded, avoided or avoidable, reduced in amount, or must otherwise be restored or returned by, or is recovered from, Lender or by any obligee of the Secured Obligations,
whether as a “voidable preference,” “fraudulent conveyance,” or otherwise, all as though such payment, performance, or transfer of Collateral had not been made. In the event that any payment, or any part thereof, is rescinded,
reduced, avoided, avoidable, restored, returned, or recovered, the Loan Documents and the Secured Obligations shall be deemed, without any further action or documentation, to have been revived and reinstated except to the extent of the full, final,
and indefeasible payment to Lender in Cash. 
 11.15 Counterparts. This Agreement and any amendments, waivers, consents or
supplements hereto may be executed in any number of counterparts, and by different parties hereto in separate counterparts, each of which when so delivered shall be deemed an original, but all of which counterparts shall constitute but one and the
same instrument. 
 11.16 No Third Party Beneficiaries. No provisions of the Loan Documents are intended, nor will be
interpreted, to provide or create any third-party beneficiary rights or any other rights of any kind in any person other than Lender and Borrower unless specifically provided otherwise herein, and, except as otherwise so provided, all provisions of
the Loan Documents will be personal and solely between the Lender and the Borrower. 
  

 32 








 11.17 Publicity. To the extent Lender desires to use Borrower’s name and logo,
including a brief description of the relationship between Borrower and Lender, in Lender’s marketing materials, Lender shall provide a copy of such materials to Borrower and shall seek consent from Borrower which may not be unreasonably
withheld; provided, however, no consent will be required in connection with mandatory SEC filings or other mandatory disclosures required by law. 
 11.18 Specific Performance. The parties hereto hereby declare that it is impossible to measure in money the damages which will accrue to Lender by reason of Borrower’s failure to perform any of the
obligations under this Agreement and agree that the terms of this Agreement shall be specifically enforceable by Lender. If Lender institutes any action or proceeding to specifically enforce the provisions hereof, any Person against whom such action
or proceeding is brought hereby waives the claim or defense therein that Lender has an adequate remedy at law, and such Person shall not offer in any such action or proceeding the claim or defense that such remedy at law exists.
