each Advance shall be $100,000. If the aggregate amount of the Advances outstanding exceeds the Maximum Loan Amount at any time, Borrower must immediately pay Lender the excess. When repaid, the Advances may not be re-borrowed. The proceeds of each
Advance may only be used to finance new Eligible Equipment or Eligible Equipment purchased within the immediately preceding 90 days (determined based upon the applicable invoice date of such Eligible Equipment); provided, however, that
on the Effective Date, Borrower may draw an Advance of up to $5,000,000 for Eligible Equipment purchased within the immediately preceding one eighty (180) days. No Advance may exceed one hundred percent (100%) of the invoice(s) for the
applicable Eligible Equipment; provided, that the Advance made on the Effective Date will not exceed fifty percent (50%) of the invoice(s) for any Eligible Equipment with invoices in excess of one hundred twenty (120) days.

Request provided that each of the conditions precedent to such Advance is satisfied as of the requested Advance Date. 
 (c) Interest. The principal balance of each Advance shall bear interest thereon from such Advance Date at the Interest Rate based on a year consisting of 360 days, with interest computed daily based on
the actual number of days elapsed. The Interest Rate will float and change on the day the Prime Rate changes from time to time.

 (d) Payment. Borrower will pay interest on each Advance on the first day of
each month, beginning the month after the Advance Date of such Advance. Borrower shall repay the aggregate principal balance of all Advances that are outstanding on June 13, 2012 in 25 equal monthly installments of principal and interest

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 deemed retroactively applied as of
the date of receipt of such payment 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, an amount equal to five percent (5%) 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 Lender’s fees and expenses set forth in Section 11.11, 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 2.4, as applicable. 
 2.4 Prepayment. At
its option upon at least 7 business days prior notice to Lender, Borrower may prepay all, but not less than all, of the outstanding Advances by paying the entire principal balance and all accrued and unpaid interest. Borrower shall prepay the
outstanding amount of all principal and accrued and unpaid interest upon the earlier to occur of a Change in Control or within 90 days of the completion of an Initial Public Offering which results in aggregate gross proceeds to Parent of less than
$30,000,000.

(ii) the date that Borrower prepays the outstanding Secured Obligations, or (iii) the date 

  
 10 

 
that the Secured Obligations become due and payable, Borrower shall pay Lender a charge of $50,000. Notwithstanding the required payment date of such charge, it shall be deemed earned by Lender
as of the Closing Date.

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 

  
 24 

 
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. 
 11.11 Professional Fees. Borrower promises to pay Lender’s fees and expenses necessary to
finalize the loan documentation, including but not limited to reasonable attorneys fees, UCC searches, filing costs, and other miscellaneous expenses. In addition, Borrower promises to pay any and all reasonable attorneys’ and other
professionals’ fees and expenses (including fees and expenses of in-house counsel) 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, if and to the extent
such information either (x) is marked as confidential by Borrower at the time of disclosure, or (y) should reasonably be understood to be confidential (the “Confidential Information”). Accordingly, Lender agrees that any
Confidential Information it may obtain in the course of acquiring, administering, or perfecting Lender’s security interest in the Collateral 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

  
 25 

 
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 otherwise generally available to the public through no fault of Lender; (c) if required or appropriate in any report, statement or testimony
submitted to any governmental authority having or claiming to have jurisdiction over Lender; (d) if required or appropriate 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. 
 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 (an “Assignee”). 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 

  
 26 

 
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. 
 11.17
Publicity. Lender may use Borrower’s name and logo, and include a brief description of the relationship between Borrower and Lender, in Lender’s marketing materials. 

11.18 Joint and Several Liability. Each of Parent and the Joined Subsidiaries is accepting joint and several liability
hereunder and under the other Loan Documents in consideration of the financial accommodations to be provided by Lender under this Agreement, for the mutual benefit, directly and indirectly, of each of Parent and the Joined Subsidiaries and in
consideration of their undertakings to accept joint and several liability for the Secured Obligations. Each of Parent and the Joined Subsidiaries, jointly and severally, hereby irrevocably, absolutely and unconditionally accepts, not merely as a
surety but also as a co-debtor, joint and several liability with respect to the payment and performance of all of the Secured Obligations (including, without limitation, any Secured Obligations arising under this Section 11.18), it being
the intention of Parent and the Joined Subsidiaries that all the Secured Obligations shall be the joint and several obligations of Parent and the Joined Subsidiaries without preferences or distinction among them. If and to the extent that any of
Parent or the Joined Subsidiaries shall fail to make any payment with respect to any of the Secured Obligations as and when due or to perform any of the Secured Obligations in accordance with the terms thereof, then in each such event, the other
Persons composing Borrower will make such payment with respect to, or perform, such Secured Obligation. Each of Parent and the Joined Subsidiaries hereby agrees that it will not enforce any of its rights of contribution or subrogation against any
other Persons composing Borrower with respect to any liability incurred by it hereunder or under any of the other Loan Documents, any payments made by it to Lender with respect to any of the Secured Obligations or any collateral security therefor
until such time as all of the Secured Obligations have been paid in full in cash. Any claim which any of Parent or the Joined Subsidiaries may have against any other Persons composing Borrower with respect to any payments to Lender hereunder or
under any other Loan Documents are hereby expressly made subordinate and junior in right of payment, without limitation as to any increases in the Secured Obligations arising hereunder or thereunder, to the prior payment in full in cash of the
Secured Obligations and, in the event of any insolvency, bankruptcy, 

  
 27 

 
receivership, liquidation, reorganization or other similar proceeding under the laws of any jurisdiction relating to any of Parent or the Joined Subsidiaries, their respective debt or assets,
whether voluntary or involuntary, all such Secured Obligations shall be paid in full in cash before any payment or distribution of any character, whether in cash, securities or other property, shall be made to any other Persons composing Borrower
therefor. 
 11.19 Administrative Borrower. Each of the Joined Subsidiaries irrevocably appoints Parent as the
borrowing agent and attorney-in-fact for all Persons composing Borrower which appointment shall remain in full force and effect unless and until Lender shall have received prior written notice signed by each of the Joined Subsidiaries that such
appointment has been revoked and that another Person has been so appointed.
