	 	2	LOAN AND TERMS OF PAYMENT 

2.1 Promise to Pay. Borrower hereby unconditionally promises to pay Bank the outstanding principal amount of all Credit Extensions
and accrued and unpaid interest thereon as and when due in accordance with this Agreement. 
 2.1.1 Revolving Advances.

 (a) Availability. Subject to the terms and conditions of this Agreement and to deduction of Reserves, Bank shall make
Advances not exceeding the Availability Amount. Amounts borrowed hereunder may be repaid and, prior to the Revolving Line Maturity Date, reborrowed, subject to the applicable terms and conditions precedent herein; provided that
(x) Revolving Advances made in 

 
excess of the Borrowing Base pursuant to clause (ii) of the definition of Availability Amount (the “Nonformula Advances”) may only be made during the last nine
(9) Business Days of each quarter, commencing with the quarter ending June 30, 2009, and only if Borrower’s Net Cash is equal to or exceeds the Asset-Based Threshold at all times during such nine (9) Business Day period;
provided further that (x) Borrower shall repay any and all Nonformula Advances on or before the tenth (10th) Business Day after the applicable date of advance, or immediately if Borrower’s Net Cash is below the Asset-Based
Threshold at any time while such Nonformula Advance is outstanding, and (y) Borrower shall pay a minimum of five (5) Business Days’ interest on each and every Nonformula Advance, regardless of whether Borrower repays such Nonformula
Advance prior to the fifth (5th) Business Day following the date of advance. 
 (b) Termination; Repayment. The
Revolving Line terminates on the Revolving Line Maturity Date, when the principal amount of all Advances, the unpaid interest thereon, and all other Obligations relating to the Revolving Line shall be immediately due and payable. 

2.1.2 Letters of Credit Sublimit. 

(a) As part of the Revolving Line, Bank shall issue or have issued Letters of Credit for Borrower’s account. The aggregate amount
available to be used for the issuance of Letters of Credit may not exceed (i) the lesser of (A) $5,000,000 or (B) the Availability Amount. If, on the Revolving Line Maturity Date, there are any outstanding Letters of Credit, then on
such date Borrower shall provide to Bank cash collateral in an amount equal to 105% of the face amount of all such Letters of Credit plus all interest, fees, and costs due or to become due in connection therewith (as estimated by Bank in its good
faith business judgment), to secure all of the Obligations relating to said Letters of Credit. All Letters of Credit shall be in form and substance acceptable to Bank in its sole discretion and shall be subject to the terms and conditions of
Bank’s standard Application and Letter of Credit Agreement (the “Letter of Credit Application”). Borrower agrees to execute any further documentation in connection with the Letters of Credit as Bank may reasonably request.
Borrower further agrees to be bound by the regulations and interpretations of the issuer of any Letters of Credit guarantied by Bank and opened for Borrower’s account or by Bank’s interpretations of any Letter of Credit issued by Bank for
Borrower’s account, and Borrower understands and agrees that Bank shall not be liable for any error, negligence, or mistake, whether of omission or commission, in following Borrower’s instructions or those contained in the Letters of
Credit or any modifications, amendments, or supplements thereto. 
 (b) The obligation of Borrower to immediately reimburse Bank
for drawings made under Letters of Credit shall be absolute, unconditional, and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement, such Letters of Credit, and the Letter of Credit Application. 

(c) Borrower may request that Bank issue a Letter of Credit payable in a Foreign Currency. If a demand for payment is made under any such
Letter of Credit, Bank shall treat such demand as an Advance to Borrower of the equivalent of the amount thereof (plus fees and charges in connection therewith such as wire, cable, SWIFT or similar charges) in Dollars at the then-prevailing rate of
exchange in San Francisco, California, for sales of the Foreign Currency for transfer to the country issuing such Foreign Currency. 

(d) To guard against fluctuations in currency exchange rates, upon the issuance of any Letter of Credit payable in a Foreign Currency,
Bank shall create a reserve (the “Letter of Credit Reserve”) under the Revolving Line in an amount equal to ten percent (10%) of the face amount of such Letter of Credit. The amount of the Letter of Credit Reserve may be
adjusted by Bank from time to time to account for fluctuations in the exchange rate. The availability of funds under the Revolving Line shall be reduced by the amount of such Letter of Credit Reserve for as long as such Letter of Credit remains
outstanding.

 2.1.3 Foreign Exchange Sublimit. As part of the Revolving Line, Borrower may enter
into foreign exchange contracts with Bank under which Borrower commits to purchase from or sell to Bank a specific amount of Foreign Currency (each, a “FX Forward Contract”) on a specified date (the “Settlement
Date”). FX Forward Contracts shall have a Settlement Date of at least one (1) FX Business Day after the contract date and shall be subject to a reserve of ten percent (10%) of each outstanding FX Forward Contract in a maximum
aggregate amount equal to Five Hundred Thousand Dollars ($500,000) (the “FX Reserve”). The aggregate amount of FX Forward Contracts at any one time may not exceed ten (10) times the amount of the FX Reserve. The amount
otherwise available for Credit Extensions under the Revolving Line shall be reduced by an amount equal to ten percent (10%) of each outstanding FX Forward Contract (the “FX Reduction Amount”). Any amounts needed to fully
reimburse Bank will be treated as Advances under the Revolving Line and will accrue interest at the interest rate applicable to Advances. 

2.1.4 Cash Management Services Sublimit. As part of the Revolving Line, Borrower may use up to the lesser of (i) $5,000,000
or (ii) the Availability Amount, for Bank’s cash management services which may include merchant services, direct deposit of payroll, business credit card, and check cashing services identified in Bank’s various cash management
services agreements (collectively, the “Cash Management Services”). Any amounts Bank pays on behalf of Borrower for any Cash Management Services will be treated as Advances under the Revolving Line and will accrue interest at the
interest rate applicable to Advances. 
 2.1.5 Term Loan B. 

(a) Bank previously made the Term Loan B to Parent pursuant to the Original Loan Agreement. The aggregate principal amount outstanding
under the Term Loan B as of the date of this Agreement is $3,472,222.32. The terms and conditions of the Original Loan Agreement relating to the Term Loan B shall continue to apply to the Term Loan B. In case of conflict, the terms of this Agreement
apply. 
 (b) Subject to Section 2.3(b), Borrower shall repay the Term Loan B in equal monthly installments of
principal (each, a “Term Loan B Payment”), each in an amount equal to $138,888.89 plus interest thereon, commencing on the last day of the month following the draw thereof. On the Term Loan B Maturity Date Borrower shall pay the
entire unpaid principal balance of the Term Loan B plus all accrued but unpaid interest thereon. 
 2.1.6 Term Loan C.

 (a) Provided that no Event of Default has occurred and is continuing and subject to the other terms and conditions hereof,
Bank shall make a new term loan available to Borrower (the “Term Loan C”) in the amount of $5,000,000 upon Borrower’s written request therefor after Borrower’s receipt of not less than $20,000,000 in proceeds of Equity
Financing on or before September 30, 2009 (the “Term Loan C Advance Date”). 
 (b) Bank shall fund the
Term Loan C on or before the end of the next Business Day following Borrower’s written request therefor made in accordance with the terms and conditions of this Section 2.1.6. On October 1, 2009, Bank’s obligation to make
the Term Loan C shall immediately terminate unless Bank has received Borrower’s written request therefor prior to such date in accordance with the terms and conditions of this Section 2.1.6. 

(c) Borrower shall repay the Term Loan C in equal monthly installments of principal (each, a “Term Loan C Payment”),
each in an amount equal to $138,888.89 plus interest thereon, commencing on the last day of the month following the draw thereof. On the Term Loan C Maturity Date Borrower shall pay the entire unpaid principal balance of the Term Loan C plus all
accrued but unpaid interest thereon. 
  

 -3- 

 2.1.7 Prepayment. Borrower may prepay the Term Loan B or the Term Loan C in whole or
in part at any time without premium or penalty. Partial prepayments of the Term Loan B or the Term Loan C shall be applied toward principal payments owing under this Section 2 in inverse order of maturity. 

2.2 Overadvances. If, at any time, the sum of (a) the outstanding principal amount of any Advances (including any amounts
used for Cash Management Services but not including the Nonformula Advances), plus (b) the face amount of any outstanding Letters of Credit (including drawn but unreimbursed Letters of Credit and any Letter of Credit Reserve), plus (c) the
FX Reduction Amount (such sum being an “Overadvance”) exceeds the lesser of either the Revolving Line or the Borrowing Base, Borrower shall immediately pay to Bank in cash such Overadvance. Without limiting Borrower’s
obligation to repay Bank any amount of the Overadvance, Borrower agrees to pay Bank interest on the outstanding amount of any Overadvance, on demand, at the Default Rate. 

2.3 Payment of Interest on the Credit Extensions. 

(a) Interest Rate. 

(a) Revolving Advances. Subject to Section 2.3(b), Revolving Advances accrue interest at the greater of
(a) five percent (5.0%), and (b) the Prime Rate in effect from time to time, plus the applicable margin as set forth in the table below: 
  

			
	 Net Cash
	  	 Margin

	Greater than or equal to $17,500,000	  	Prime Rate + 1.0%
	Greater than or equal to $10,000,000 but less than $17,500,000	  	Prime Rate + 1.5%
	Less than $10,000,000	  	Prime Rate + 2.0%

(b) Term Loan B. Bank previously made the Term Loan B to Parent pursuant to the Original Loan Agreement. Subject
to Section 2.3(b) of this Agreement, the Term Loan B accrues interest at the Prime Rate in effect from time to time, plus one percent (1.0%) per annum. 

(c) Term Loan C. Subject to Section 2.3(b), the Term Loan C accrues interest at the greater of
(a) six percent (6.0%) per annum, and (b) the Prime Rate in effect from time to time, plus two percent (2.0%) per annum. 

(b) Default Rate. Immediately upon the occurrence and during the continuance of an Event of Default, Obligations shall bear
interest at a rate per annum which is five percentage points above the rate that is otherwise applicable thereto (the “Default Rate”). Payment or acceptance of the increased interest rate provided in this Section 2.3(b)
is not a permitted alternative to timely payment and shall not constitute a waiver of any Event of Default or otherwise prejudice or limit any rights or remedies of Bank. 

(c) Adjustment to Interest Rate. Changes to the interest rate of any Credit Extension based on changes to the Prime Rate shall be
effective on the effective date of any change to the Prime Rate and to the extent of any such change. 
  

 -4- 

 (d) 360-Day Year. Interest shall be computed on the basis of a 360-day year for the
actual number of days elapsed. 
 (e) Debit of Accounts. Bank may debit any of Borrower’s deposit accounts,
including the Designated Deposit Account, for principal and interest payments or any other amounts Borrower owes Bank when due. These debits shall not constitute a set-off. 

(f) Payment; Interest Computation; Float Charge. Interest on the Advances is payable monthly on the last calendar day of each
month. In computing interest on the Obligations, all payments received after 12:00 p.m. Pacific time on any day shall be deemed received on the next Business Day. All payments received on any day when Borrower’s Net Cash is below the
Asset-Based Threshold shall be subject to a “float” charge in an amount equal to one (1) Business Day’s interest, at the interest rate applicable to the Loans. Said float charge is not included in interest for purposes of
computing Minimum Monthly Interest (if any) under this Agreement. The float charge for each month shall be payable on the last day of the month. Bank shall not, however, be required to credit Borrower’s account for the amount of any item of
payment which is unsatisfactory to Bank in its good faith business judgment, and Bank may charge Borrower’s Designated Deposit Account for the amount of any item of payment which is returned to Bank unpaid. 

2.4 Fees. Borrower shall pay to Bank: 

(a) Commitment Fee. 

(a) A fully earned, nonrefundable commitment fee for the Revolving Advance in the amount of $125,000 per year, due and
payable in advance on the Effective Date and each anniversary thereof; provided that the commitment fee due on the Effective Date will be prorated based on a $75,000 fee received on March 26, 2009. 

(b) A fully earned, nonrefundable commitment fee for the Term Loan C in the amount of $25,000, due and payable in advance
on the Effective Date. 
 (b) Unused Revolving Line Fee. A fee (the “Unused Revolving Line Facility
Fee”), payable monthly, in arrears, on a calendar year basis, in an amount equal to 0.375 percent (0.375%) per annum of the average unused portion of the Revolving Line, as determined by Bank. The unused portion of the Revolving Line, for
the purposes of this calculation, shall include amounts reserved under the Cash Management Services Sublimit for products provided and under the Foreign Exchange Sublimit for FX Forward Contracts. Borrower shall not be entitled to any credit, rebate
or repayment of any Unused Revolving Line Facility Fee previously earned by Bank pursuant to this Section notwithstanding any termination of the Agreement, or suspension or termination of Bank’s obligation to make loans and advances hereunder;

 (c) Audit Fee. Bank’s customary fees for audits (currently $850 per day per person), plus all out-of-pocket
expenses; 
 (d) Letter of Credit Fee. Bank’s customary fees and expenses for the issuance or renewal of Letters of
Credit, including, without limitation, a Letter of Credit Fee of one and one-quarter percent (1.25%) per annum of the face amount of each Letter of Credit issued, payable in advance upon the issuance, each anniversary of the issuance, and the
renewal, if any, of such Letter of Credit by Bank; and 
 (e) Collateral Handling Fee. A monthly Collateral handling fee
in the amount of $500, due and payable on the last day of each month, if Borrower’s Net Cash is below the Asset-Based Threshold at any time while any Obligations are outstanding.

Obligations, a continuing security interest in, and pledges to Bank, the Collateral, wherever located, whether now owned or hereafter acquired or arising, and all proceeds and products thereof. Borrower represents, warrants, and covenants that the
security interest granted herein is and shall at all times continue to be a first priority perfected security interest in the Collateral (subject only to Permitted Liens that may have superior priority to Bank’s Lien under this Agreement). If
Borrower shall acquire a commercial tort claim in which the potential recovery exceeds $50,000 per claim 
  

 -7- 

 
or an aggregate of $100,000 per year, Borrower shall promptly notify Bank in a writing signed by Borrower of the general details thereof and grant to Bank 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 Bank. 

If this Agreement is terminated, Bank’s Lien in the Collateral shall continue until the Obligations (other than inchoate indemnity
obligations) are repaid in full in cash. Upon payment in full in cash of the Obligations and at such time as Bank’s obligation to make Credit Extensions has terminated, Bank shall, at Borrower’s sole cost and expense, release its Liens in
the Collateral and all rights therein shall revert to Borrower. 
 4.2 Authorization to File Financing Statements.
Borrower hereby authorizes Bank to file financing statements, without notice to Borrower, with all appropriate jurisdictions to perfect or protect Bank’s interest or rights hereunder, including a notice that any disposition of the Collateral,
by either Borrower or any other Person, shall be deemed to violate the rights of Bank under the Code. Such financing statements may indicate the Collateral as “all assets of the Debtor” or words of similar effect, or as being of an equal
or lesser scope, or with greater detail, all in Bank’s discretion. 
  

	 	5	REPRESENTATIONS AND WARRANTIES 

Borrower represents and warrants as follows: 

5.1 Due Organization, Authorization; Power and Authority. Borrower is duly existing and in good standing as a Registered
Organization in its jurisdiction of formation and is qualified and licensed to do business and is in good standing in any jurisdiction in which the conduct of its business or its ownership of property requires that it be qualified except where the
failure to do so could not reasonably be expected to have a material adverse effect on Borrower’s business. In connection with this Agreement, Borrower has delivered to Bank completed certificates each signed by Borrower, respectively, entitled
“Perfection Certificate”. Borrower represents and warrants to Bank that (a) Borrower’s exact legal name is that indicated on the Perfection Certificate and on the signature page hereof; (b) Borrower is an organization
of the type, and is organized in the jurisdiction, set forth in the Perfection Certificate; (c) Borrower is a Registered Organization and the Perfection Certificate accurately sets forth Borrower’s organizational identification number or
accurately states that Borrower has none; (d) the Perfection Certificate accurately sets forth Borrower’s place of business, or, if more than one, its chief executive office as well as Borrower’s mailing address (if different than its
chief executive office); (e) Borrower (and each of its predecessors) has not, in the past five (5) years, changed its jurisdiction of formation, organizational structure or type, or any organizational number assigned by its jurisdiction;
and (f) all other information set forth on the Perfection Certificate pertaining to Borrower and each of its Subsidiaries is accurate and complete (it being understood and agreed that Borrower may from time to time update certain information in
the Perfection Certificate after the Effective Date to the extent permitted by one or more specific provisions in this Agreement). 

The execution, delivery and performance by Borrower of the Loan Documents to which it is a party have been duly authorized, and do not
(i) conflict with any of Borrower’s organizational documents, (ii) contravene, conflict with, constitute a default under or violate any material Requirement of Law, (iii) contravene, conflict or violate any applicable order,
writ, judgment, injunction, decree, determination or award of any Governmental Authority by which Borrower or any its Subsidiaries or any of its property or assets may be bound or affected, (iv) require any action by, filing, registration, or
qualification with, or Governmental Approval from, any Governmental Authority (except such Governmental Approvals which have already been obtained and are in full force and effect) or (v) constitute an event of default under any material
agreement by which Borrower is bound. Borrower is not in default under any agreement to which it is a party or by which it is bound in which the default could have a material adverse effect on Borrower’s business. 

 

 -8- 

 5.2 Capital Stock and Ownership. The Capital Stock of the Borrower and each of
its Subsidiaries has been duly authorized and validly issued and is fully paid and non assessable. Schedule 5.2 correctly sets forth the ownership interest of each Borrower and each of its Subsidiaries as of the Effective Date. 

5.3 Collateral. 

Borrower has good title to, has rights in, and the power to transfer each item of the Collateral upon which it purports to grant a Lien
hereunder, free and clear of any and all Liens except Permitted Liens. Borrower has no deposit accounts other than the deposit accounts with Bank, the deposit accounts, if any, described in the Perfection Certificate delivered to Bank in connection
herewith, or of which Borrower has given Bank notice and taken such actions as are necessary to give Bank a perfected security interest therein. The Accounts are bona fide, existing obligations of the Account Debtors. 

The Collateral is not in the possession of any third party bailee (such as a warehouse) except as otherwise provided in the Perfection
Certificate. None of the components of the Collateral shall be maintained at locations other than as provided in the Perfection Certificate or as permitted pursuant to Section 7.2. In the event that Borrower, after the date hereof,
intends to store or otherwise deliver any portion of the Collateral to a bailee, then Borrower will first receive the written consent of Bank and such bailee must execute and deliver a bailee agreement in form and substance satisfactory to Bank in
its sole discretion. 
 All Inventory is in all material respects of good and marketable quality, free from material defects.

 Borrower is the sole owner of its intellectual property, except for exclusive licenses for certain OEM customers and
non-exclusive licenses granted to its customers in the ordinary course of business. To the best of Borrower’s knowledge, each patent is valid and enforceable and no part of the intellectual property has been judged invalid or unenforceable, in
whole or in part, and to the best of Borrower’s knowledge, no claim has been made that any part of the intellectual property violates the rights of any third party except to the extent such claim could not reasonably be expected to have a
material adverse effect on Borrower’s business. 
 5.4 Accounts Receivable; Inventory. 

(a) For each Account with respect to which Advances are requested, on the date each Advance is requested and made, such Account shall be
an Eligible Account. 
 (b) All statements made and all unpaid balances appearing in all invoices, instruments and other
documents evidencing the Eligible Accounts are and shall be true and correct and all such invoices, instruments and other documents, and all of Borrower’s Books are genuine and in all respects what they purport to be. Whether or not an Event of
Default has occurred and is continuing, Bank may notify any Account Debtor owing Borrower money of Bank’s security interest in such funds and verify the amount of such Eligible Account. All sales and other transactions underlying or giving rise
to each Eligible Account shall comply in all material respects with all applicable laws and governmental rules and regulations. Borrower has no knowledge of any actual or imminent Insolvency Proceeding of any Account Debtor whose accounts are
Eligible Accounts in any Transaction Report. To the best of Borrower’s knowledge, all signatures and endorsements on all documents, instruments, and agreements relating to all Eligible Accounts are genuine, and all such documents, instruments
and agreements are legally enforceable in accordance with their terms. 
 (c) For any item of Inventory consisting of Eligible
Inventory in any Transaction Report, such Inventory (i) consists of finished goods, in good, new, and salable condition, which is not perishable, returned, consigned, obsolete, not sellable, damaged, or defective, and is not comprised of
demonstrative 
  

 -9- 

 
or custom inventory, works in progress, packaging or shipping materials, or supplies; (ii) meets all applicable governmental standards; (iii) has been manufactured in compliance with
the Fair Labor Standards Act; (iv) is not subject to any Liens, except the first priority Liens granted or in favor of Bank under this Agreement or any of the other Loan Documents; and (v) is located at the locations identified by Borrower
in the Perfection Certificate where it maintains Inventory (or any location permitted under Section 7.2). 
 5.5
Litigation. There are no actions or proceedings pending or, to the knowledge of the Responsible Officers, threatened in writing by or against Borrower or any of its Subsidiaries which involve or could reasonably be expected to involve more than
Five Hundred Thousand Dollars ($500,000). 
 5.6 No Material Deviation in Financial Statements. All consolidated
financial statements for Borrower and any of its Subsidiaries delivered to Bank fairly present in all material respects Borrower’s consolidated financial condition and Borrower’s consolidated results of operations. There has not been any
material deterioration in Borrower’s consolidated financial condition since the date of the most recent financial statements submitted to Bank. 

5.7 Solvency. The fair salable value of Borrower’s assets (including goodwill minus disposition costs) exceeds the fair value
of its liabilities; Borrower is not left with unreasonably small capital after the transactions in this Agreement; and Borrower is able to pay its debts (including trade debts) as they mature. 

5.8 Regulatory Compliance. Borrower is not an “investment company” or a company “controlled” by an
“investment company” under the Investment Company Act of 1940, as amended. Borrower is not engaged as one of its important activities in extending credit for margin stock (under Regulations X, T and U of the Federal Reserve Board of
Governors). Borrower has complied in all material respects with the Federal Fair Labor Standards Act. Neither Borrower nor any of its Subsidiaries is a “holding company” or an “affiliate” of a “holding company” or a
“subsidiary company” of a “holding company” as each term is defined and used in the Public Utility Holding Company Act of 2005. Borrower has not violated any laws, ordinances or rules, the violation of which could reasonably be
expected to have a material adverse effect on its business. None of Borrower’s or any of its Subsidiaries’ properties or assets has been used by Borrower or any Subsidiary or, to the best of Borrower’s knowledge, by previous Persons,
in disposing, producing, storing, treating, or transporting any hazardous substance other than legally. Borrower and each of its Subsidiaries have obtained all consents, approvals and authorizations of, made all declarations or filings with, and
given all notices to, all Government Authorities that are necessary to continue their respective businesses as currently conducted. 

5.9 Subsidiaries; Investments. Borrower does not own any stock, partnership interest or other equity securities except for
Permitted Investments. 
 5.10 Tax Returns and Payments; Pension Contributions. Borrower has timely filed all required
tax returns and reports, or extensions thereof, and Borrower has timely paid all foreign, federal, state and local taxes, assessments, deposits and contributions owed by Borrower. Borrower may defer payment of any contested taxes, provided that
Borrower (a) in good faith contests its obligation to pay the taxes by appropriate proceedings promptly and diligently instituted and conducted, (b) notifies Bank in writing of the commencement of, and any material development in, the
proceedings, (c) posts bonds or takes any other steps required to prevent the governmental authority levying such contested taxes from obtaining a Lien upon any of the Collateral that is other than a “Permitted Lien”. Borrower is
unaware of any claims or adjustments proposed for any of Borrower’s prior tax years which could result in additional taxes becoming due and payable by Borrower. Borrower has paid all amounts necessary to fund all present pension, profit sharing
and deferred compensation plans in accordance with their terms, and Borrower has not withdrawn from participation in, and has not permitted partial or complete termination 

 

 -10- 

 
of, or permitted the occurrence of any other event with respect to, any such plan which could reasonably be expected to result in any liability of Borrower, including any liability to the Pension
Benefit Guaranty Corporation or its successors or any other governmental agency. 
 5.11 Use of Proceeds. Borrower shall
use the proceeds of the Credit Extensions solely as working capital and to fund its general business requirements and not for personal, family, household or agricultural purposes. 

5.12 Full Disclosure. No written representation, warranty or other statement of Borrower in any certificate or written statement
given to Bank, as of the date such representation, warranty, or other statement was made, taken together with all such written certificates and written statements given to Bank, contains any untrue statement of a material fact or omits to state a
material fact necessary to make the statements contained in the certificates or statements not misleading (it being recognized by Bank that the projections and forecasts provided by Borrower in good faith and based upon reasonable assumptions are
not viewed as facts and that actual results during the period or periods covered by such projections and forecasts may differ from the projected or forecasted results). 

 

	 	6	AFFIRMATIVE COVENANTS 

Borrower shall do all of the following: 

6.1 Government Compliance. Maintain its and all its Subsidiaries’ legal existence and good standing in their respective
jurisdictions of formation and maintain qualification in each jurisdiction in which the failure to so qualify would reasonably be expected to have a material adverse effect on Borrower’s business or operations. Borrower shall comply, and have
each Subsidiary comply, with all laws, ordinances and regulations to which it is subject, noncompliance with which could have a material adverse effect on Borrower’s business. 

6.2 Financial Statements, Reports, Certificates. 

(a) Provide Bank with the following:

(a) Schedules and Documents Relating to Accounts. Deliver to Bank transaction reports and schedules of collections, as
provided in Section 6.2, on Bank’s standard forms; provided however, that Borrower’s failure to execute and deliver the same shall not affect or limit Bank’s Lien and other rights in all of Borrower’s Accounts,
nor shall Bank’s failure to advance or lend against a specific Account affect or limit Bank’s Lien and other rights therein. If requested by Bank, Borrower shall furnish Bank with copies (or, at Bank’s request, originals) of all
contracts, orders, invoices, and other similar documents, and all shipping instructions, delivery receipts, bills of lading, and other evidence of delivery, for any goods the sale or disposition of which gave rise to such Accounts. In addition,
Borrower shall deliver to Bank, on its request, the originals of all instruments, chattel paper, security agreements, guarantees and other documents and property evidencing or securing any Accounts, in the same form as received, with all necessary
indorsements, and copies of all credit memos. 
 (b) Disputes. Promptly notify Bank of all disputes or claims relating to
Accounts. Borrower may forgive (completely or partially), compromise, or settle any Account for less than payment in full, or agree to do any of the foregoing so long as (i) Borrower does so in good faith, in a commercially reasonable manner,
in the ordinary course of business, in arm’s-length transactions, and reports the same to Bank in the regular reports provided to Bank; (ii) no Default or Event of Default has occurred and is continuing; and (iii) after taking into
account all such discounts, settlements and forgiveness, the total outstanding Advances (including any amounts used for Cash Management Services but not including any Nonformula Advances) will not exceed the lesser of either the Revolving Line or
the Borrowing Base. 
 (c) Collection of Accounts. Direct all Accounts to a lockbox account or such other “blocked
account” as Bank may specify, pursuant to a blocked account agreement. If Borrower’s Net Cash is equal to or exceeds the Asset-Based Threshold, the lockbox will be swept nightly to Borrower’s primary operating account with Bank. If
Borrower’s Net Cash is below the Asset-Based Threshold, all proceeds of the Accounts shall be applied to the Obligations pursuant to the terms of Section 9.4 hereof and when the outstanding balance on the Obligations is zero (0),
the lockbox funds will be promptly transferred to Borrower’s primary operating account with Bank.

any Account Debtor returns any Inventory to Borrower, Borrower shall promptly (i) determine the reason for such return, (ii) issue a credit memorandum to the Account Debtor in the appropriate amount, and (iii) provide a copy of such

notify Bank of the return of the Inventory. 
 (e) Verification. Bank may, from time to time, verify directly with
the respective Account Debtors the validity, amount and other matters relating to the Accounts, either in the name of Borrower or Bank or such other name as Bank may choose. 

(f) No Liability. Bank shall not be responsible or liable for any shortage or discrepancy in, damage to, or loss or
destruction of, any goods, the sale or other disposition of which gives rise to an Account, or for any error, act, omission, or delay of any kind occurring in the settlement, failure to settle, collection or failure to collect any Account, or for
settling any Account in good faith for less than the full amount thereof, nor shall Bank be deemed to be responsible for any of Borrower’s obligations under any contract or agreement giving rise to an Account. Nothing herein shall, however,
relieve Bank from liability for its own gross negligence or willful misconduct. 
 6.4 Remittance of Proceeds. Except as
otherwise provided in Section 6.3(c), deliver, in kind, all proceeds arising from the disposition of any Collateral to Bank in the original form in which received by Borrower not later than three (3) Business Days after receipt by

of the sale of worn out or obsolete Equipment disposed of by Borrower in good faith in an arm’s length transaction for an aggregate purchase price of $500,000 or less (for all such transactions in any fiscal year). Borrower agrees that it will
not commingle proceeds of Collateral with any of Borrower’s other funds or property, but will hold such proceeds separate and apart from such other funds and property and in an express trust for Bank. Nothing in this Section limits the
restrictions on disposition of Collateral set forth elsewhere in this Agreement. 
 6.5 Taxes; Pensions. Timely file, and
require each of its Subsidiaries to timely file, all required tax returns and reports and timely pay, and require each of its Subsidiaries to timely pay, all foreign, federal, state and local taxes, assessments, deposits and contributions owed by

all amounts necessary to fund all present pension, profit sharing and deferred compensation plans in accordance with their terms. 

6.6 Access to Collateral; Books and Records; Verification of Accounts. 

(a) At reasonable times, on three (3) Business Day’s notice (provided no notice is required if an Event of Default has occurred
and is continuing), Bank, or its agents, shall have the right to inspect the Collateral and the right to audit and copy Borrower’s Books. The foregoing inspections and audits shall be at Borrower’s expense, and the charge therefor shall be
$850 per person per day (or such higher amount as shall represent Bank’s then-current standard charge for the same), plus reasonable out-of-pocket expenses. In the event Borrower and Bank schedule an audit more than ten (10) days in
advance, and Borrower cancels or seeks to reschedules the audit with less than ten (10) days written notice to Bank, then (without limiting any of Bank’s rights or remedies), Borrower shall pay Bank a fee of $1,000 plus any out-of-pocket
expenses incurred by Bank to compensate Bank for the anticipated costs and expenses of the cancellation or rescheduling. 
  

 -13- 

 (b) Bank may, from time to time, verify directly with the respective Account Debtors the
validity, amount and other matters relating to the Accounts, by means of mail, telephone or otherwise, either in the name of Borrowers or Bank or such other name as Bank may choose. Bank or its designee may, at any time, notify Account Debtors that
Bank has a security interest in the Accounts and, after the occurrence and during the continuation of an Event of Default, that payment on the Accounts is to be made directly to Bank. 

6.7 Insurance. Keep its business and the Collateral insured for risks and in amounts standard for companies in Borrower’s
industry and location and as Bank may reasonably request. Insurance policies shall be in a form, with companies, and in amounts that are satisfactory to Bank. All property policies shall have a lender’s loss payable endorsement showing Bank as
an additional loss payee and waive subrogation against Bank, and all liability policies shall show, or have endorsements showing, Bank as an additional insured. All policies (or the loss payable and additional insured endorsements) shall provide
that the insurer shall endeavor to give Bank at least twenty (20) days notice before canceling, or declining to renew its policy. At Bank’s request, Borrower shall deliver certified copies of policies and evidence of all premium payments.
In an Event of Default, proceeds payable under any property policy shall, at Bank’s option, be payable to Bank on account of the Obligations. If Borrower fails to obtain insurance as required under this Section 6.7 or to pay any
amount or furnish any required proof of payment to third persons and Bank, Bank may, upon substantially concurrent notice to Borrower, make all or part of such payment or obtain such insurance policies required in this Section 6.7, and
take any reasonable and prudent action under the policies. 
 6.8 Operating Accounts. Provide Bank five (5) days
prior written notice before establishing any Collateral Account at or with any bank or financial institution other than Bank or Bank’s Affiliates. For each Collateral Account that Borrower at any time maintains, Borrower shall cause the
applicable bank or financial institution (other than Bank) at or with which any Collateral Account is maintained to execute and deliver a Control Agreement or other appropriate instrument with respect to such Collateral Account to perfect
Bank’s Lien in such Collateral Account in accordance with the terms hereunder. The provisions of the previous sentence shall not apply to deposit accounts exclusively used for payroll, payroll taxes and other employee wage and benefit payments
to or for the benefit of Borrower’s employees and identified to Bank by Borrower as such. In addition, Borrower shall not be required to provide Bank with signed account control agreements for their deposit accounts maintained at Bank of

Bank, without expense to Bank, Borrower and its officers, employees and agents and Borrower’s books and records, to the extent that Bank may deem them reasonably necessary to prosecute or defend any third-party suit or proceeding instituted by
or against Bank with respect to any Collateral or relating to Borrower.

 8.3 Material Adverse
Change. A Material Adverse Change occurs;

8.7 Judgments. One or more judgments, orders, or decrees for the payment of money in an amount, individually or in the aggregate,
of at least One Hundred Thousand Dollars ($100,000) (not covered by independent third-party insurance as to which liability has been accepted by such insurance carrier) shall be rendered against Borrower and shall remain unsatisfied, unvacated, or
unstayed for a period of ten (10) days after the entry thereof (provided that no Credit Extensions will be made prior to the satisfaction, vacation, or stay of such judgment, order, or decree);

	 	9	BANK’S RIGHTS AND REMEDIES 

9.1 Rights and Remedies. While an Event of Default occurs and continues Bank may, without notice or demand, do any or all of the
following: 
 (a) declare all Obligations immediately due and payable (but if an Event of Default described in
Section 8.5 occurs all Obligations are immediately due and payable without any action by Bank); 
 (b) stop
advancing money or extending credit for Borrower’s benefit under this Agreement or under any other agreement between Borrower and Bank; 

(c) demand that Borrower (i) deposit cash with Bank in an amount equal to the aggregate amount of any Letters of Credit remaining
undrawn, as collateral security for the repayment of any future drawings under such Letters of Credit, and Borrower shall forthwith deposit and pay such amounts, and (ii) pay in advance all Letter of Credit fees scheduled to be paid or payable
over the remaining term of any Letters of Credit; 
 (d) terminate any FX Forward Contracts; 

(e) settle or adjust disputes and claims directly with Account Debtors for amounts on terms and in any order that Bank considers
advisable, notify any Person owing Borrower money of Bank’s security interest in such funds, and verify the amount of such account; 

(f) make any payments and do any acts it considers necessary or reasonable to protect the Collateral and/or its security interest in the
Collateral. Borrower shall assemble the Collateral if Bank requests and make it available as Bank designates. Bank may enter premises where the Collateral is located, take and maintain possession of any part of the Collateral, and pay, purchase,
contest, or compromise any Lien which appears to be prior or superior to its security interest and pay all expenses incurred. Borrower grants Bank a license to enter and occupy any of its premises, without charge, to exercise any of Bank’s
rights or remedies; 
 (g) apply to the Obligations any (i) balances and deposits of Borrower it holds, or (ii) any
amount held by Bank owing to or for the credit or the account of Borrower; 
 (h) ship, reclaim, recover, store, finish,
maintain, repair, prepare for sale, advertise for sale, and sell the Collateral. Bank is hereby granted a non-exclusive, royalty-free license or other right to use, without charge, Borrower’s labels, patents, copyrights, mask works, rights of
use of any name, trade secrets, trade names, trademarks, service marks, and advertising matter, or any similar property as it pertains to the Collateral, in completing production of, advertising for sale, and selling any Collateral and, in
connection with Bank’s exercise of its rights under this Section, Borrower’s rights under all licenses and all franchise agreements inure to Bank’s benefit; 

(i) place a “hold” on any account maintained with Bank and/or deliver a notice of exclusive control, any entitlement order, or
other directions or instructions pursuant to any Control Agreement or similar agreements providing control of any Collateral; 

(j) demand and receive possession of Borrower’s Books; and 

(k) exercise all rights and remedies available to Bank under the Loan Documents or at law or equity, including all remedies provided
under the Code (including disposal of the Collateral pursuant to the terms thereof). 
 9.2 Power of Attorney. Borrower
hereby irrevocably appoints Bank as its lawful attorney-in-fact, exercisable upon the occurrence and during the continuance of an Event of Default, to: (a) endorse Borrower’s name on any checks or other forms of payment or security;
(b) sign Borrower’s name 
  

 -18- 

 
on any invoice or bill of lading for any Account or drafts against Account Debtors; (c) settle and adjust disputes and claims about the Accounts directly with Account Debtors, for amounts
and on terms Bank determines reasonable; (d) make, settle, and adjust all claims under Borrower’s insurance policies; (e) pay, contest or settle any Lien, charge, encumbrance, security interest, and adverse claim in or to the
Collateral, or any judgment based thereon, or otherwise take any action to terminate or discharge the same; and (f) transfer the Collateral into the name of Bank or a third party as the Code permits. Borrower hereby appoints Bank as its lawful
attorney-in-fact to sign Borrower’s name on any documents necessary to perfect or continue the perfection of Bank’s security interest in the Collateral regardless of whether an Event of Default has occurred until all Obligations have been
satisfied in full and Bank is under no further obligation to make Credit Extensions hereunder. Bank’s foregoing appointment as Borrower’s attorney in fact, and all of Bank’s rights and powers, coupled with an interest, are irrevocable
until all Obligations have been fully repaid and performed and Bank’s obligation to provide Credit Extensions terminates. 

9.3 Protective Payments. If Borrower fails to obtain the insurance called for by Section 6.7 or fails to
pay any premium thereon or fails to pay any other amount which Borrower is obligated to pay under this Agreement or any other Loan Document, Bank may obtain such insurance or make such payment, and all amounts so paid by Bank are Bank Expenses and
immediately due and payable, bearing interest at the then highest applicable rate, and secured by the Collateral. Bank will make reasonable efforts to provide Borrower with notice of Bank obtaining such insurance at the time it is obtained or within
a reasonable time thereafter. No payments by Bank are deemed an agreement to make similar payments in the future or Bank’s waiver of any Event of Default. 

9.4 Application of Payments and Proceeds. Borrower shall have no right to specify the order or the accounts to which Bank shall
allocate or apply any payments required to be made by Borrower to Bank or otherwise received by Bank under this Agreement when any such allocation or application is not specified elsewhere in this Agreement. If an Event of Default has occurred and
is continuing or if Borrower’s Net Cash is below the Asset-Based Threshold, Bank may apply any funds in its possession, whether from Borrower account balances, payments, proceeds realized as the result of any collection of Accounts or other
disposition of the Collateral, or otherwise, to the Obligations in such order as Bank shall determine in its sole discretion. Any surplus shall be paid to Borrower by credit to the Designated Deposit Account or to other Persons legally entitled
thereto; Borrower shall remain liable to Bank for any deficiency. If Bank, in its good faith business judgment, directly or indirectly enters into a deferred payment or other credit transaction with any purchaser at any sale of Collateral, Bank
shall have the option, exercisable at any time, of either reducing the Obligations by the principal amount of the purchase price or deferring the reduction of the Obligations until the actual receipt by Bank of cash therefor. 

9.5 Bank’s Liability for Collateral. So long as Bank complies with reasonable banking practices regarding the safekeeping of
the Collateral in the possession or under the control of Bank, Bank shall not be liable or responsible for: (a) the safekeeping of the Collateral; (b) any loss or damage to the Collateral; (c) any diminution in the value of the
Collateral; or (d) any act or default of any carrier, warehouseman, bailee, or other Person. Borrower bears all risk of loss, damage or destruction of the Collateral. 

9.6 No Waiver; Remedies Cumulative. Bank’s failure, at any time or times, to require strict performance by Borrower of any
provision of this Agreement or any other Loan Document shall not waive, affect, or diminish any right of Bank thereafter to demand strict performance and compliance herewith or therewith. No waiver hereunder shall be effective unless signed by Bank
and then is only effective for the specific instance and purpose for which it is given. Bank’s rights and remedies under this Agreement and the other Loan Documents are cumulative. Bank has all rights and remedies provided under the Code, by
law, or in equity. Bank’s exercise of one right or remedy is not an election, and Bank’s waiver of any Event of Default is not a continuing waiver. Bank’s delay in exercising any remedy is not a waiver, election, or acquiescence.

 9.7 Reserves. 

(a) Without limiting the right of Bank to cease making Advances on an Event of Default, Bank shall have the right, from time to time and
upon reasonable notice to Borrower, to establish and deduct the Reserves from the amount of Advances, Letters of Credit and other financial accommodations under the lending formula(s) provided in the Agreement. In exercising its rights under this
Section 9.7, Bank shall act in a commercially reasonable manner and deal with Borrowers fairly and in good faith. 

(b) Notwithstanding the foregoing, at any time Borrower’s Net Cash is below the Asset-Based Threshold, Bank shall establish and
deduct from the amount of Advances, Letters of Credit and other financial accommodations under the lending formula provided in the Agreement a reserve in the amount of fifty percent (50%) of any amounts outstanding under the Term Loan B and the
Term Loan C. 
 9.8 Demand Waiver. Borrower waives demand, notice of default or dishonor, notice of payment and
nonpayment, notice of any default, nonpayment at maturity, release, compromise, settlement, extension, or renewal of accounts, documents, instruments, chattel paper, and guarantees held by Bank on which Borrower is liable.

	 	11	CHOICE OF LAW, VENUE, JURY TRIAL WAIVER AND JUDICIAL REFERENCE 

California law governs the Loan Documents without regard to principles of conflicts of law. Borrower and Bank each submit to the exclusive
jurisdiction of the State and Federal courts in Santa Clara County, California; provided however, that nothing in this Agreement shall be deemed to operate to preclude Bank from bringing suit or taking other legal action in any other
jurisdiction to realize on the Collateral or any other security for the Obligations, or to enforce a judgment or other court order in favor 

 

 -20- 

 
of Bank. Borrower expressly submits and consents in advance to such jurisdiction in any action or suit commenced in any such court, and Borrower hereby waives any objection that it may have based
upon lack of personal jurisdiction, improper venue, or forum non conveniens and hereby consents to the granting of such legal or equitable relief as is deemed appropriate by such court. Borrower hereby waives personal service of the summons,
complaints, and other process issued in such action or suit and agrees that service of such summons, complaints, and other process may be made by registered or certified mail addressed to Borrower at the address set forth in Section 10
of this Agreement and that service so made shall be deemed completed upon the earlier to occur of Borrower’s actual receipt thereof or three (3) days after deposit in the U.S. mails, proper postage prepaid. 

TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, BORROWER AND BANK EACH WAIVE THEIR RIGHT TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF
ACTION ARISING OUT OF OR BASED UPON THIS AGREEMENT, THE LOAN DOCUMENTS OR ANY CONTEMPLATED TRANSACTION, INCLUDING CONTRACT, TORT, BREACH OF DUTY AND ALL OTHER CLAIMS. THIS WAIVER IS A MATERIAL INDUCEMENT FOR BOTH PARTIES TO ENTER INTO THIS
AGREEMENT. EACH PARTY HAS REVIEWED THIS WAIVER WITH ITS COUNSEL. 
 WITHOUT INTENDING IN ANY WAY TO LIMIT THE PARTIES’
AGREEMENT TO WAIVE THEIR RESPECTIVE RIGHT TO A TRIAL BY JURY, if the above waiver of the right to a trial by jury is not enforceable, the parties hereto agree that any and all disputes or controversies of any nature between them arising at any time
shall be decided by a reference to a private judge, mutually selected by the parties (or, if they cannot agree, by the Presiding Judge of the Santa Clara County, California Superior Court) appointed in accordance with California Code of Civil
Procedure Section 638 (or pursuant to comparable provisions of federal law if the dispute falls within the exclusive jurisdiction of the federal courts), sitting without a jury, in Santa Clara County, California; and the parties hereby submit
to the jurisdiction of such court. The reference proceedings shall be conducted pursuant to and in accordance with the provisions of California Code of Civil Procedure §§ 638 through 645.1, inclusive. The private judge shall have the
power, among others, to grant provisional relief, including without limitation, entering temporary restraining orders, issuing preliminary and permanent injunctions and appointing receivers. All such proceedings shall be closed to the public and
confidential and all records relating thereto shall be permanently sealed. If during the course of any dispute, a party desires to seek provisional relief, but a judge has not been appointed at that point pursuant to the judicial reference
procedures, then such party may apply to the Santa Clara County, California Superior Court for such relief. The proceeding before the private judge shall be conducted in the same manner as it would be before a court under the rules of evidence
applicable to judicial proceedings. The parties shall be entitled to discovery which shall be conducted in the same manner as it would be before a court under the rules of discovery applicable to judicial proceedings. The private judge shall oversee
discovery and may enforce all discovery rules and order applicable to judicial proceedings in the same manner as a trial court judge. The parties agree that the selected or appointed private judge shall have the power to decide all issues in the
action or proceeding, whether of fact or of law, and shall report a statement of decision thereon pursuant to the California Code of Civil Procedure § 644(a). Nothing in this paragraph shall limit the right of any party at any time to exercise
self-help remedies, foreclose against collateral, or obtain provisional remedies. The private judge shall also determine all issues relating to the applicability, interpretation, and enforceability of this paragraph.

connection with the transactions contemplated by the Loan Documents; and (b) all losses or Bank Expenses incurred, or paid by such Indemnified Person from, following, or arising from transactions between Bank and Borrower (including reasonable

Agreement has terminated pursuant to its terms and all Obligations (other than inchoate indemnity obligations and any other obligations which, by their terms, are to survive the termination of this Agreement) have been satisfied. The obligation of
Borrower in Section 12.3 to indemnify Bank shall survive until the statute of limitations with respect to such claim or cause of action shall have run.

for payment, performance and satisfaction in full of the Obligations and that such liability is independent of the duties, obligations, and liabilities of the other Borrower. Bank may bring a separate action or actions on each, any, or all of the

forth in this Agreement, each Loan shall be made upon Borrower’s irrevocable written notice delivered to Bank in the form of a Notice of Borrowing, each executed by a Responsible Officer of Borrower or his or her designee or without
instructions if the Loan is necessary to meet Obligations which have become due. Bank may rely on any telephone notice given by a person whom Bank believes is a Responsible Officer or designee. Borrower will indemnify Bank for any loss Bank suffers
due to such reliance. Such Notice of Borrowing must be received by Bank prior to 12:00 p.m. Pacific time, (i) at least three (3) Business Days prior to the requested Funding Date, in the case of LIBOR Loans, and (ii) on the requested

(1) month. The proceeds of all such Loans will then be made available to Borrower on the Funding Date by Bank by transfer to the Designated Deposit Account and, subsequently, by wire transfer to such other account as Borrower may instruct in
the Notice of Borrowing. No Loans shall be deemed made to Borrower, and no interest shall accrue on any such Loan, until the related funds have been deposited in the Designated Deposit Account. 

 

	 	3.6	Conversion and Continuation Elections. 

(a) So long as (i) no Event of Default exists; (ii) Borrower shall not have sent any notice of termination of
this Agreement; and (iii) Borrower shall have complied with such customary procedures as Bank has established from time to time for Borrower’s requests for LIBOR Loans, Borrower may, upon irrevocable written notice to Bank:

(1) proposed Conversion Date or Continuation Date; 

(2) aggregate amount of the Loans to be converted or continued;

(d) Any LIBOR Loans shall, at Bank’s option, convert into Prime Rate Loans in the event that (i) an Event of
Default shall exist, or (ii) the aggregate principal amount of the Prime Rate Loans which have been previously converted to LIBOR Loans, or the aggregate principal amount of existing LIBOR Loans continued, as the case may be, at the beginning
of an Interest Period shall at any time during such Interest Period exceed the maximum amount available for Loans of such type Loans under this Agreement. Borrower agrees to pay Bank, upon demand by Bank (or Bank may, at its option, charge the
Designated Deposit Account or any other account Borrower maintains with Bank) any amounts required to compensate Bank for any loss (including loss of anticipated profits), cost, or expense incurred by Bank, as a result of the conversion of LIBOR
Loans to Prime Rate Loans pursuant to this Section 3.6(d). 
 (e) Notwithstanding anything to the
contrary contained herein, Bank shall not be required to purchase Dollar deposits in the London interbank market or other applicable LIBOR market to fund any LIBOR Loans, but the provisions hereof shall be deemed to apply as if Bank had purchased

Notwithstanding any other provision of this Agreement to the contrary, the following provisions shall govern with respect to LIBOR Loans as to the matters covered: 

(a) Determination of Applicable Interest Rate. As soon as practicable on each Interest Rate Determination Date,
Bank shall determine (which determination shall, absent manifest error in calculation, be final, conclusive and binding upon all parties) the interest rate that shall apply to the LIBOR Loans for which an interest rate is then being determined for
the applicable Interest Period and shall promptly give notice thereof (in writing or by telephone confirmed in writing) to Borrower. 

(b) Inability to Determine Applicable Interest Rate. In the event that Bank shall have determined (which
determination shall be final and conclusive and binding upon all parties hereto), on any Interest Rate Determination Date with respect to any LIBOR Loan, that by reason of circumstances affecting the London interbank market adequate and fair means
do not exist for ascertaining the interest rate applicable to such Loan on the basis provided for in the definition of LIBOR, Bank shall on such date give notice (by facsimile or by telephone confirmed in writing) to Borrower of such determination,
whereupon (i) no Loans may be made as, or converted to, LIBOR Loans until such time as Bank notifies Borrower that the circumstances giving rise to such notice no longer exist, and (ii) any Notice of Borrowing or Notice of
Conversion/Continuation given by Borrower with respect to Loans in respect of which such determination was made shall be deemed to be rescinded by Borrower. 

(c) Compensation for Breakage or Non-Commencement of Interest Periods. Borrower shall compensate Bank, upon
written request by Bank (which request shall set forth the manner and method of computing such compensation), for all losses, expenses, unrealized gains and liabilities (including any interest paid by Bank to lenders of funds borrowed by it to make
or carry its LIBOR Loans, any loss, expense or liability incurred by Bank in connection with the liquidation or re-employment of such funds, and, in the case of complete or partial principal payments or conversions of LIBOR Loans prior to the last
day of the applicable Interest Period, any amount by which (A) the additional interest which would have been payable on the amount so prepaid or converted had it not been paid or converted until the last day of the applicable Interest Period
exceeds (B) the interest which would have been recoverable by Bank by placing the amount so received on deposit in the certificate of deposit markets, the offshore currency markets, or United States Treasury investment products, as the case may
be, for a period starting on the date on which it was so paid or converted and ending on the last day of such Interest Period at the interest rate determined by Bank in its reasonable discretion), if any, that Bank may incur: (i) if for any
reason (other than a default by Bank or due to any failure of Bank to fund LIBOR Loans due to impracticability or illegality under Sections 3.8(c) and 3.8(d)) a borrowing or a conversion to or continuation of any LIBOR Loan does not
occur on a date specified in a Notice of Borrowing or a Notice of Conversion/Continuation, as the 

 
case may be, or (ii) if for any reason (including voluntary or mandatory prepayment or acceleration) any complete or partial principal payment or any conversion of any of Borrower’s
LIBOR Loans occurs on a date prior to the last day of an Interest Period applicable to that Loan. Bank’s determination as to such amount shall be conclusive absent manifest error. Borrower shall immediately notify Borrower’s account
officer at Bank if any of the situations described in (ii) above occur. 
 (d) Assumptions Concerning
Funding of LIBOR Loans. Calculation of all amounts payable to Bank under this Section 3.7 and under Section 3.8 shall be made as though Bank had actually funded each of its relevant LIBOR Loans through the purchase of a
LIBOR deposit bearing interest at the rate obtained pursuant to the definition of LIBOR Rate in an amount equal to the amount of such LIBOR Loan and having a maturity comparable to the relevant Interest Period; provided, however, that Bank may fund
each of its LIBOR Loans in any manner it sees fit and the foregoing assumptions shall be utilized only for the purposes of calculating amounts payable under this Section 3.7 and under Section 3.8. 

(e) LIBOR Loans After Default. After the occurrence and during the continuance of an Event of Default,
(i) Borrower may not elect to have a Loan be made or continued as, or converted to, a LIBOR Loan after the expiration of any Interest Period then in effect for such Loan and (ii) subject to the provisions of Section 3.7(c), any
Notice of Conversion/Continuation given by Borrower with respect to a requested conversion/continuation that has not yet occurred shall, at Bank’s option, be deemed to be rescinded by Borrower and be deemed a request to convert or continue
Loans referred to therein as Prime Rate Loans. 
  

	 	3.8	Additional Requirements/Provisions Regarding LIBOR Loans. 

(a) Borrower shall pay Bank, upon demand by Bank, from time to time such amounts as Bank may determine to be necessary to
compensate it for any costs incurred by Bank that Bank determines are attributable to its making or maintaining of any amount receivable by Bank hereunder in respect of any LIBOR Loans relating thereto (such increases in costs and reductions in
amounts receivable being herein called “Additional Costs”), in each case resulting from any Regulatory Change which: 

(i) changes the basis of taxation of any amounts payable to Bank under this Agreement in respect of any LIBOR Loans
(other than changes which affect taxes measured by or imposed on the overall net income of Bank by the jurisdiction in which Bank has its principal office); 

(ii) imposes or modifies any reserve, special deposit or similar requirements relating to any extensions of credit or
other assets of, or any deposits with, or other liabilities of Bank (including any LIBOR Loans or any deposits referred to in the definition of LIBOR); or 

 (iii) imposes any other condition affecting this Agreement (or any of such
extensions of credit or liabilities). 
 Bank will notify Borrower of any event occurring after the Effective Date which will
entitle Bank to compensation pursuant to this Section 3.8(a) as promptly as practicable after it obtains knowledge thereof and determines to request such compensation. Bank will furnish Borrower with a statement setting forth the basis
and amount of each request by Bank for compensation under this Section 3.8(a). Determinations and allocations by Bank for purposes of this Section 3.8(a) of the effect of any Regulatory Change on its costs of maintaining its
obligations to make LIBOR Loans, of making or maintaining LIBOR Loans, or on amounts receivable by it in respect of LIBOR Loans, and of the additional amounts required to compensate Bank in respect of any Additional Costs, shall be conclusive absent
manifest error. 
 (b) If Bank shall determine that the adoption or implementation of any applicable law, rule,
regulation, or treaty regarding capital adequacy, or any change therein, or any change in the interpretation or administration thereof by any governmental authority, central bank, or comparable agency charged with the interpretation or
administration thereof, or compliance by Bank (or its applicable lending office) with any request or directive regarding capital adequacy (whether or not having the force of law) of any such authority, central bank, or comparable agency, has or
would have the effect of reducing the rate of return on capital of Bank or any person or entity controlling Bank as a consequence of its obligations hereunder to a level below that which Bank or any person or entity controlling Bank could have
achieved but for such adoption, change, or compliance (taking into consideration policies with respect to capital adequacy) by an amount deemed by Bank to be material, then from time to time, within five (5) days after demand by Bank, Borrower
shall pay to Bank such additional amount or amounts as will compensate Bank for such reduction. A statement of Bank claiming compensation under this Section 3.8(b) and setting forth the additional amount or amounts to be paid to it
hereunder shall be conclusive absent manifest error. 
 (c) If, at any time, Bank, in its sole and absolute
discretion, determines that (i) the amount of LIBOR Loans for periods equal to the corresponding Interest Periods are not available to Bank in the offshore currency interbank markets, or (ii) LIBOR does not accurately reflect the cost to
Bank of lending the LIBOR Loans, then Bank shall promptly give notice thereof to Borrower. Upon the giving of such notice, Bank’s obligation to make the LIBOR Loans shall terminate; provided, however, LIBOR Loans shall not terminate if Bank and
Borrower agree in writing to a different interest rate applicable to LIBOR Loans. 
 (d) If it shall become
unlawful for Bank to continue to fund or maintain any LIBOR Loans, or to perform its obligations hereunder, upon demand by Bank, Borrower shall prepay the LIBOR Loans in full with accrued interest thereon and all other amounts payable by Borrower
hereunder (including, without limitation, any amount payable in connection with such prepayment 

 
pursuant to Section 3.7(c)(ii)). Notwithstanding the foregoing, to the extent a determination by Bank as described above relates to a LIBOR Loan then being requested by Borrower
pursuant to a Notice of Borrowing or a Notice of Conversion/Continuation, Borrower shall have the option, subject to the provisions of Section 3.7(c)(ii), to (i) rescind such Notice of Borrowing or Notice of Conversion/Continuation
by giving notice (by facsimile or by telephone confirmed in writing) to Bank of such rescission on the date on which Bank gives notice of its determination as described above, or (ii) modify such Notice of Borrowing or Notice of
Conversion/Continuation to obtain a Prime Rate Loan or to have outstanding Loans converted into or continued as Prime Rate Loans by giving notice (by facsimile or by telephone confirmed in writing) to Bank of such modification on the date on which
Bank gives notice of its determination as described above.”

 8Amendment to the Amended and Restated Strategic Alliance Agreement

 Exhibit 10.18.5 

EXECUTION VERSION 

SIXTH AMENDMENT 

This Sixth Amendment (the “Sixth Amendment”), dated as of August 9, 2010, but effective as set forth in Paragraph
10 below, to the Amended and Restated Strategic Alliance Agreement (as amended) is entered into by and between PENWEST PHARMACEUTICALS CO., a corporation organized and existing under the laws of the State of Washington, with its principal place of
business at 39 Old Ridgebury Road, Danbury, Connecticut 06810 (“Penwest”), and ENDO PHARMACEUTICALS INC., a corporation organized and existing under the laws of the State of Delaware, with its principal place of business at 100
Painters Drive, Chadds Ford, Pennsylvania 19317 (“Endo”) (each, a “Party” and collectively, the “Parties”). 

WITNESSETH: 

WHEREAS, Endo and Penwest are parties to that certain Amended and Restated Strategic Alliance Agreement, dated as of April 2,
2002, as amended by that certain Amendment Agreement, dated as of January 7, 2007, that certain Second Amendment, effective as of July 14, 2008, that certain Third Amendment, effective as of January 1, 2009, that certain Consent
Agreement, dated as of June 8, 2009, that certain Fourth Amendment, effective as of April 8, 2010 and that certain Fifth Amendment, dated as of June 8, 2010 (collectively, the “Agreement”); 

WHEREAS, Endo, Penwest and West Acquisition Corp. (“Merger Sub”), concurrently with the execution and delivery of
this Sixth Amendment, have entered into an Agreement and Plan of Merger (the “Merger Agreement”), pursuant to which (i) Merger Sub will commence an Offer (as defined in the Merger Agreement) to purchase all of the outstanding
shares of common stock of Penwest upon the terms and subject to the conditions set forth in the Merger Agreement, and (ii) following the consummation of the Offer, Merger Sub will merge with and into Penwest in accordance with the Washington
Business Corporation Act and the General Corporation Law of the State of Delaware; 
 WHEREAS, following the Offer
Closing (as defined in the Merger Agreement), Endo will be the beneficial owner of a majority of the issued and outstanding shares of common stock of Penwest and will be entitled to designate a majority of the directors on the Company Board (as
defined in the Merger Agreement); and 
 WHEREAS, if Merger Sub consummates the Offer, Penwest and Endo desire to further
amend the Agreement as specified herein, effective as of the Offer Closing, to reflect the ownership of Penwest following the Offer Closing. 

NOW, THEREFORE, in consideration of the foregoing, of the mutual covenants and undertakings set forth below, and for other good
and valuable consideration, the receipt and adequacy of which are hereby acknowledged, the Parties hereby agree as follows: 
  

	1.	Certain Defined Terms. Words and phrases that are introduced by initial capitals and which are not otherwise defined in this Sixth Amendment shall have the same
meaning as in the Agreement. All references to “Section”, unless otherwise specified, are intended to refer to a section of the Agreement and all references to “Paragraph”, unless otherwise specified, are intended to refer to a
paragraph of this Sixth Amendment. 

	2.	Penwest’s Rights to Receive Royalties. Endo shall continue to pay, and Penwest shall continue to have the right to receive, royalties or other payments as
specified in the Agreement. 

  

	3.	Control of the Product. The Parties hereby agree that, and notwithstanding anything to the contrary in the Agreement (but subject to Paragraphs 2 and 4), from
and after the Offer Closing, Endo shall have sole discretion with respect to all decisions and actions pertaining to the Product and the Licensed Oxymorphone Products. 

 

	4.	Committee Action; Alliance Committee. Notwithstanding anything to the contrary in the Agreement, from and after the Offer Closing, any and all matters under the
Agreement that are to be determined, decided, approved or accepted by Committee Action, the Alliance Committee, Penwest or both Parties, or for which the Alliance Committee’s or Penwest’s consent is required, shall be determined, decided,
approved or accepted by or consented to (as the case may be) by Endo in its sole discretion (except amendments of, or modifications to, the Agreement, which shall continue to require a writing signed by both Parties). In connection with the
foregoing, from and after the Offer Closing, all provisions of the Agreement that specify procedures required to obtain any such determination, decision, approval, acceptance or consent by Committee Action, the Alliance Committee, Penwest or both
Parties shall be automatically deleted from the Agreement (including, for clarity, the existence and powers of the Alliance Committee, which, from and after the Offer Closing, shall be automatically disbanded and shall have no further rights or
obligations under the Agreement). 

  

	5.	Termination By Penwest. Notwithstanding anything to the contrary in the Agreement, from and after the Offer Closing, Penwest shall not have any right to
terminate the Agreement, except with Endo’s prior written consent. 

  

	6.	Best Commercial Efforts. Notwithstanding anything to the contrary in the Agreement, from and after the Offer Closing, Endo shall have no obligations to Penwest
under Section 4.1 of the Agreement (including no obligations to exercise Best Commercial Efforts during the Marketing Period), or any other obligations, to manufacture, market, promote and sell the Product and the Licensed Oxymorphone Products.

  

	7.	Non-Solicitation Obligations. Notwithstanding anything to the contrary in the Agreement, from and after the Offer Closing, neither Party shall have any
obligations to the other Party under the Agreement with respect to non-solicitation of employees and consultants under the Agreement. 

  

	8.	Other Provisions. From and after the Offer Closing, if any provisions of the Agreement are rendered meaningless or irrelevant in light of the amendments
specified herein, such provisions shall be deleted from the Agreement. 

  

 2 

	9.	Conflicts. For clarity, in the event of any conflict between the terms of this Sixth Amendment and the Agreement, this Sixth Amendment shall control.

  

	10.	Effective Date. This Sixth Amendment shall be effective immediately following the Offer Closing (as defined in the Merger Agreement). For the sake of clarity, if
the Offer Closing does not occur in accordance with the terms of the Merger Agreement and the Merger Agreement is terminated, then this Sixth Amendment shall not take effect. For the sake of further clarity, the Parties agree and acknowledge that
the execution of this Sixth Amendment, and the possibility that this Sixth Amendment would become effective on the Offer Closing as set forth herein, will not, at any time prior to the Offer Closing, prejudice either Party’s rights under the
Agreement . 

  

	11.	Counterparts. This Sixth Amendment may be executed simultaneously in any number of counterparts, each of which shall be deemed an original of the Party or
Parties who executed such counterpart, but all of which together shall constitute one and the same instrument. In making proof of this Sixth Amendment, it shall not be necessary to produce or account for more than one counterpart evidencing
execution by each Party. Facsimile or scanned copies of original signatures by either Party shall be deemed to be originals of such signatures. 

  

	12.	Entire Agreement. This Sixth Amendment, together with the Agreement, contains the Parties’ entire understanding with regard to the subject matter hereof and
thereof and supersedes, revokes, terminates, and cancels any and all other arrangements and agreements, whether oral or written, between the Parties relating to the subject matter hereof and thereof. 

 

	13.	Severability. If any provision of this Sixth Amendment shall be held invalid, illegal or unenforceable, such provision shall be enforced (from and after the
Offer Closing) to the maximum extent permitted by law and the Parties’ fundamental intentions hereunder and the remaining provisions shall not be affected or impaired. 

 

	14.	Governing Law. This Sixth Amendment and all actions arising out of or in connection with this Sixth Amendment shall be governed by and construed in accordance
with the laws of the State of New York, without regard to the conflict of law principles of any other jurisdiction. Any disputes arising out of or relating to this Sixth Amendment shall be resolved in accordance with Section 12.2 and Article 13
of the Agreement as if such dispute were a dispute under the Agreement.

the date written above by their duly authorized officers.
