to be in form and substance satisfactory to Lender. 
 4.3 Duration of Security Interest. Lender’s security
interest in the Collateral shall continue until the payment in full and the satisfaction of all Obligations and termination of Lender’s commitment to fund the Loans, whereupon such security interest shall terminate. Lender shall, at
Borrower’s sole cost and expense, execute such further documents and take such further actions as may be reasonably necessary to make effective the release contemplated by this Section 4.3, including duly executing and delivering
termination statements for filing in all relevant jurisdictions under the Code. 
 4.4 Location and Possession of
Collateral. Other than in the normal course of Borrower’s business, the Collateral is and shall remain in the possession of Borrower at its location listed on the cover page hereof, or as set forth in the Disclosure Schedule or as disclosed

 4.5 Delivery of Additional Documentation Required. Borrower shall from
time to time execute and deliver to Lender, at the request of Lender, all financing statements and other documents Lender may reasonably request, in form satisfactory to Lender, to perfect and continue Lender’s perfected security interests in

Borrower’s perfection in the Collateral.

that the Liens granted to it hereunder shall be subordinate to the Liens to secure the Indebtedness permitted under sub-clause (e) of the definition of Permitted Indebtedness. Lender agrees that the Liens granted to it hereunder in Third Party
Equipment shall be subordinate to the Liens of future lenders providing equipment financing and equipment lessors for equipment and other personal property acquired by Borrower after the date hereof (“Third Party Equipment”);
provided that in the case of equipment financings and leasing such Liens are confined solely to the equipment so financed and the proceeds thereof and are Permitted Liens. Notwithstanding the foregoing, the Obligations hereunder shall
not be subordinate in right of payment to any obligations to other lenders, equipment lenders or equipment lessors and Lender’s rights and remedies hereunder shall not in any way be subordinate to the rights and remedies of any such lenders or
equipment lessors, except as may specifically be set forth in a subordination agreement with such lendor or lessor. So long as no Event of Default has occurred, Lender agrees to execute and deliver such agreements and documents as may be reasonably
requested by Borrower from time to time which set forth the lien subordination described in this Section 4.8 and are reasonably acceptable to Lender. Lender shall have no obligation to execute any agreement or document which would impose
obligations, restrictions or lien priority on Lender which are less favorable to Lender than those described in this Section 4.8.

Documents and Borrower has failed to cure such default within fifteen (15) days of the occurrence of such default. During this fifteen (15) day period, the failure to cure the default is not an Event of Default (but no Loan will be made

 9. Lender’s Rights and Remedies. 

9.1 Rights and Remedies. Upon the occurrence of any Default or Event of Default, Lender shall not have any further
obligation to advance money or extend credit to or for the benefit of Borrower. In addition, upon the occurrence of an Event of Default, Lender shall have the rights, options, duties and remedies of a secured party as permitted by law and, in
addition to and without limitation of the foregoing, Lender may, at its election, without notice of election and without demand, do any one or more of the following, all of which are authorized by Borrower: 

(a) Acceleration of Obligations. Declare all Obligations, whether evidenced by this Agreement, by any of the other Loan Documents, or
otherwise, including (i) any accrued and unpaid interest, (ii) the amounts which would have otherwise come due under Section 2.3(b)(ii) if the Loans had been voluntarily prepaid, (iii) the unpaid principal balance of the Loans
and (iv) all other sums, if any, that shall have become due and payable hereunder, immediately due and payable (provided that upon the occurrence of an Event of Default described in Section 8.12 or 8.13 all Obligations
shall become immediately due and payable without any action by Lender); 
 (b) Protection of Collateral. Make such payments and do
such acts as Lender considers necessary or reasonable to protect Lender’s security interest in the Collateral. Borrower agrees to assemble the Collateral if Lender so requires and to make the Collateral available to Lender as Lender may
designate. Borrower authorizes Lender and its designees and agents to enter the premises where the Collateral is located, to take and maintain possession of the Collateral, or any part of it, and to pay, purchase, contest, or compromise any Lien
which in Lender’s determination appears or is claimed to be prior or superior to its security interest and to pay all expenses incurred in connection therewith. With respect to any of Borrower’s owned premises, Borrower hereby grants
Lender a license to enter into possession of such premises and to occupy the same, without charge, for up to one hundred twenty (120) days in order to exercise any of Lender’s rights or remedies provided herein, at law, in equity, or
otherwise; 
 (c) Preparation of Collateral for Sale. Ship, reclaim, recover, store, finish, maintain, repair, prepare for sale,
advertise for sale, and sell (in the manner provided for herein) the Collateral. Lender and its agents and any purchasers at or after foreclosure are hereby granted a non-exclusive, irrevocable, perpetual, fully paid, royalty-free license or other
right, solely pursuant to the provisions of this Section 9.1, to use, without charge, Borrower’s Intellectual Property, including without limitation, labels, patents, copyrights, rights of use of any name, trade secrets, trade
names, trademarks, service marks, and advertising matter, or any 

  
 25 








 
Property of a similar nature, now or at any time hereafter owned or acquired by Borrower or in which Borrower now or at any time hereafter has any rights; provided that such license
shall only be exercisable in connection with the disposition of Collateral upon Lender’s exercise of its remedies hereunder; 
 (d)
Sale of Collateral. Sell the Collateral at either a public or private sale, or both, by way of one or more contracts or transactions, for cash or on terms, in such manner and at such places (including Borrower’s premises) as Lender
determines are commercially reasonable; and 
 (e) Purchase of Collateral. Credit bid and purchase all or any portion of the
Collateral at any public sale. 
 Any deficiency that exists after disposition of the Collateral as provided above will be paid immediately by Borrower.

 9.2 Set Off Right. Lender may set off and apply to the Obligations any and all indebtedness at any time owing to or
for the credit or the account of Borrower or any other assets of Borrower in Lender’s possession or control. 
 9.3
Effect of Sale. Upon the occurrence of an Event of Default, to the extent permitted by law, Borrower covenants that it will not at any time insist upon or plead, or in any manner whatsoever claim or take any benefit or advantage of, any stay
or extension law now or at any time hereafter in force, nor claim, take nor insist upon any benefit or advantage of or from any law now or hereafter in force providing for the valuation or appraisement of the Collateral or any part thereof prior to
any sale or sales thereof to be made pursuant to any provision herein contained, or to the decree, judgment or order of any court of competent jurisdiction; nor, after such sale or sales, claim or exercise any right under any statute now or
hereafter made or enacted by any state or otherwise to redeem the property so sold or any part thereof, and, to the full extent legally permitted, except as to rights expressly provided herein, hereby expressly waives for itself and on behalf of
each and every Person, except decree or judgment creditors of Borrower, acquiring any interest in or title to the Collateral or any part thereof subsequent to the date of this Agreement, all benefit and advantage of any such law or laws, and
covenants that it will not invoke or utilize any such law or laws or otherwise hinder, delay or impede the execution of any power herein granted and delegated to Lender, but will suffer and permit the execution of every such power as though no such
power, law or laws had been made or enacted. Any sale, whether under any power of sale hereby given or by virtue of judicial proceedings, shall operate to divest all right, title, interest, claim and demand whatsoever, either at law or in equity, of
Borrower in and to the Property sold, and shall be a perpetual bar, both at law and in equity, against Borrower, its successors and assigns, and against any and all Persons claiming the Property sold or any part thereof under, by or through
Borrower, its successors or assigns. 
 9.4 Power of Attorney in Respect of the Collateral. Borrower does hereby
irrevocably appoint Lender (which appointment is coupled with an interest), the true and lawful attorney in fact of Borrower with full power of substitution, for it and in its name to file any notices of security interests, financing statements and
continuations and amendments thereof 

  
 26 








 
pursuant to the Code or federal law, as may be necessary to perfect, or to continue the perfection of Lender’s security interests in the Collateral. Borrower does hereby irrevocably appoint
Lender (which appointment is coupled with an interest) on the occurrence of an Event of Default, the true and lawful attorney in fact of Borrower with full power of substitution, for it and in its name: (a) to ask, demand, collect, receive,
receipt for, sue for, compound and give acquittance for any and all rents, issues, profits, avails, distributions, income, payment draws and other sums in which a security interest is granted under Section 4 with full power to settle,
adjust or compromise any claim thereunder as fully as if Lender were Borrower itself; (b) to receive payment of and to endorse the name of Borrower to any items of Collateral (including checks, drafts and other orders for the payment of money)
that come into Lender’s possession or under Lender’s control; (c) to make all demands, consents and waivers, or take any other action with respect to, the Collateral; (d) in Lender’s discretion to file any claim or take any
other action or proceedings, either in its own name or in the name of Borrower or otherwise, which Lender may reasonably deem necessary or appropriate to protect and preserve the right, title and interest of Lender in and to the Collateral;
(e) endorse Borrower’s name on any checks or other forms of payment or security; (f) sign Borrower’s name on any invoice or bill of lading for any account or drafts against account debtors; (g) make, settle, and adjust all
claims under Borrower’s insurance policies; (h) settle and adjust disputes and claims about the accounts directly with account debtors, for amounts and on terms Lender determines reasonable; (i) transfer the Collateral into the name
of Lender or a third party as the Code permits; and (j) to otherwise act with respect thereto as though Lender were the outright owner of the Collateral. 

9.5 Lender’s Expenses. If Borrower fails to pay any amounts or furnish any required proof of payment due to third
persons or entities, as required under the terms of this Agreement, then Lender may do any or all of the following: (a) make payment of the same or any part thereof; or (b) obtain and maintain insurance policies of the type discussed in
Section 6.8 of this Agreement, and take any action with respect to such policies as Lender deems prudent. Any amounts paid or deposited by Lender shall constitute Lender’s Expenses, shall be immediately due and payable, shall bear
interest at the Default Rate and shall be secured by the Collateral. Any payments made by Lender shall not constitute an agreement by Lender to make similar payments in the future or a waiver by Lender of any Event of Default under this Agreement.
Borrower shall pay all reasonable fees and expenses, including without limitation, Lender’s Expenses, incurred by Lender in the enforcement or attempt to enforce any of the Obligations hereunder not performed when due. 

9.6 Remedies Cumulative. Lender’s rights and remedies under this Agreement, the Loan Documents, and all other
agreements shall be cumulative. Lender shall have all other rights and remedies not inconsistent herewith as provided under the Code, by law, or in equity. No exercise by Lender of one right or remedy shall be deemed an election, and no waiver by
Lender of any Event of Default on Borrower’s part shall be deemed a continuing waiver. No delay by Lender shall constitute a waiver, election, or acquiescence by it. 

  
 27 








 9.7 Application of Collateral Proceeds. The proceeds and/or avails of the
Collateral, or any part thereof, and the proceeds and the avails of any remedy hereunder (as well as any other amounts of any kind held by Lender, at the time of or received by Lender after the occurrence of an Event of Default hereunder) shall be
paid to and applied as follows: 
 (a) First, to the payment of out-of-pocket costs and expenses, including all amounts expended to
preserve the value of the Collateral, of foreclosure or suit, if any, and of such sale and the exercise of any other rights or remedies, and of all proper fees, expenses, liability and advances, including reasonable legal expenses and
attorneys’ fees, incurred or made hereunder by Lender, including, without limitation, Lender’s Expenses; 
 (b) Second, to
the payment to Lender of the amount then owing or unpaid on the Loans for any accrued and unpaid interest, the amounts which would have otherwise come due under Section 2.3(b)(ii), if the Loans had been voluntarily prepaid, the principal
balance of the Loans, and all other Obligations with respect to the Loans (provided, however, if such proceeds shall be insufficient to pay in full the whole amount so due, owing or unpaid upon the Loans, then to the unpaid interest
thereon, then to the amounts which would have otherwise come due under Section 2.3(b)(ii), if the Loans had been voluntarily prepaid, then to the principal balance of the Loans, and then to the payment of other amounts then payable to Lender
under any of the Loan Documents); and 
 (c) Third, to the payment of the surplus, if any, to Borrower, its successors and assigns,
or to the Person lawfully entitled to receive the same. 
 9.8 Reinstatement of Rights. If Lender shall have proceeded
to enforce any right under this Agreement or any other Loan Document by foreclosure, sale, entry or otherwise, and such proceedings shall have been discontinued or abandoned for any reason or shall have been determined adversely, then and in every
such case (unless otherwise ordered by a court of competent jurisdiction), Lender shall be restored to its former position and rights hereunder with respect to the Property subject to the security interest created under this Agreement. 

10. Waivers; Indemnification. 

10.1 Demand; Protest. Borrower waives demand, protest, notice of protest, 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 at any time held by Lender on which Borrower may in any
way be liable. 
 10.2 Lender’s Liability for Collateral. So long as Lender complies with its obligations, if
any, under the Code, Lender shall not in any way or manner be liable or responsible for: (a) the safekeeping of the Collateral; (b) any loss or damage thereto occurring or arising in any manner or fashion from any cause other than
Lender’s gross negligence or willful misconduct; (c) any diminution in the value thereof; or (d) any act or default of any carrier, warehouseman, bailee, forwarding agency, or other Person whomsoever. All risk of loss, damage or
destruction of the Collateral shall be borne by Borrower. 
 10.3 Indemnification and Waiver. Whether or not the
transactions contemplated hereby shall be consummated: 
 (a) General Indemnity. Borrower agrees upon demand to pay or reimburse
Lender for all liabilities, obligations and out-of-pocket expenses, including Lender’s Expenses and reasonable fees and expenses of counsel for Lender from time to time arising in connection 

  
 28 








 
with the enforcement or collection of sums due under the Loan Documents, and in connection with any amendment or modification of the Loan Documents or any “work-out” in connection with
the Loan Documents. Borrower shall indemnify, reimburse and hold Lender, and each of its respective successors, assigns, agents, attorneys, officers, directors, equity holders, servants, agents and employees (each an “Indemnified
Person”) harmless from and against all liabilities, losses, damages, actions, suits, demands, claims of any kind and nature (including claims relating to environmental discharge, cleanup or compliance), all costs and expenses whatsoever to
the extent they may be incurred or suffered by such Indemnified Person in connection therewith (including reasonable attorneys’ fees and expenses), fines, penalties (and other charges of any applicable Governmental Authority), licensing fees
relating to any item of Collateral, damage to or loss of use of property (including consequential or special damages to third parties or damages to Borrower’s property), or bodily injury to or death of any person (including any agent or
employee of Borrower) (each, a “Claim”), directly or indirectly relating to or arising out of the use of the proceeds of the Loans or otherwise, the falsity of any representation or warranty of Borrower or Borrower’s failure to
comply with the terms of this Agreement or any other Loan Document. The foregoing indemnity shall cover, without limitation, (i) any Claim in connection with a design or other defect (latent or patent) in any item of equipment or product
included in the Collateral, (ii) any Claim for infringement of any patent, copyright, trademark or other intellectual property right, (iii) any Claim resulting from the presence on or under or the escape, seepage, leakage, spillage,
discharge, emission or release of any Hazardous Materials on the premises owned, occupied or leased by Borrower, including any Claims asserted or arising under any Environmental Law, (iv) any Claim for negligence or strict or absolute liability
in tort, or (v) any Claim asserted as to or arising under any Account Control Agreement or any Landlord Agreement; provided, however, Borrower shall not indemnify Lender for any liability incurred by Lender as a direct and sole
result of Lender’s gross negligence or willful misconduct. Such indemnities shall continue in full force and effect, notwithstanding the expiration or termination of this Agreement. Upon Lender’s written demand, Borrower shall assume and
diligently conduct, at its sole cost and expense, the entire defense of Lender, each of its members, partners, and each of their respective, agents, employees, directors, officers, equity holders, successors and assigns against any indemnified Claim
described in this Section 10.3(a). Borrower shall not settle or compromise any Claim against or involving Lender without first obtaining Lender’s written consent thereto, which consent shall not be unreasonably withheld. 

(b) Waiver. NOTWITHSTANDING ANYTHING TO THE CONTRARY CONTAINED IN THIS AGREEMENT OR ANYWHERE ELSE, BORROWER AGREES THAT IT SHALL NOT
SEEK FROM LENDER UNDER ANY THEORY OF LIABILITY (INCLUDING ANY THEORY IN TORTS), ANY SPECIAL, INDIRECT, CONSEQUENTIAL OR PUNITIVE DAMAGES. 

(c) Survival; Defense. The obligations in this Section 10.3 shall survive payment of all other Obligations pursuant to
Section 12.8. At the election of any Indemnified Person, Borrower shall defend such Indemnified Person using legal counsel satisfactory to such Indemnified Person in such Person’s reasonable discretion, at the sole cost and expense
of Borrower. All amounts owing under this Section 10.3 shall be paid within thirty (30) days after written demand.

 12.4 Entire Agreement; Construction; Amendments and Waivers. 

(a) Entire Agreement. This Agreement and each of the other Loan Documents dated as of the date hereof, taken together, constitute and
contain the entire agreement between Borrower and Lender and supersede any and all prior agreements, negotiations, correspondence, understandings and communications between the parties, whether written or oral, respecting the subject matter hereof.
Borrower acknowledges that it is not relying on any representation or agreement made by Lender or any employee, attorney or agent thereof, other than the specific agreements set forth in this Agreement and the Loan Documents. 

(b) Construction. This Agreement is the result of negotiations between and has been reviewed by each of Borrower and Lender as of the
date hereof and their respective counsel; accordingly, this Agreement shall be deemed to be the product of the parties hereto, and no ambiguity shall be construed in favor of or against Borrower or Lender. Borrower and Lender agree that they intend
the literal words of this Agreement and the other Loan Documents and that no parol evidence shall be necessary or appropriate to establish Borrower’s or Lender’s actual intentions. 

(c) Amendments and Waivers. Any and all amendments or modifications, from any provision of this Agreement or of any of the other Loan
Documents shall not be effective without the written consent of Lender and Borrower. Any and all discharges or waivers of, or consents to any departures from any provision of this Agreement or of any of the other Loan Documents shall not be
effective without the written consent of Lender. Any waiver or consent with respect to any provision of the Loan Documents shall be effective only in the specific instance and for the specific purpose for which it was given. No notice to or demand

Agreement. 
 12.8 Survival. All covenants, representations and warranties made in this Agreement shall continue in
full force and effect so long as any Obligations or commitment to fund remain outstanding. The obligations of Borrower to indemnify Lender with respect to the expenses, damages, losses, costs and liabilities described in Section 10.3
shall survive until all applicable statute of limitations periods with respect to actions that may be brought against Lender have run. 

  
 31 








 13. Relationship of Parties. Borrower and Lender acknowledge, understand and agree that
the relationship between Borrower, on the one hand, and Lender, on the other, is, and at all time shall remain solely that of a borrower and lender. Lender shall not under any circumstances be construed to be a partner or a joint venturer of
Borrower or any of its Affiliates; nor shall Lender under any circumstances be deemed to be in a relationship of confidence or trust or a fiduciary relationship with Borrower or any of its Affiliates, or to owe any fiduciary duty to Borrower or any
of its Affiliates. Lender does not undertake or assume any responsibility or duty to Borrower or any of its Affiliates to select, review, inspect, supervise, pass judgment upon or otherwise inform Borrower or any of its Affiliates of any matter in
connection with its or their Property, any Collateral held by Lender or the operations of Borrower or any of its Affiliates. Borrower and each of its Affiliates shall rely entirely on their own judgment with respect to such matters, and any review,
inspection, supervision, exercise of judgment or supply of information undertaken or assumed by Lender in connection with such matters is solely for the protection of Lender and neither Borrower nor any Affiliate is entitled to rely thereon. 

14. Confidentiality. All information (other than periodic reports filed by Borrower with the Securities and Exchange Commission)
disclosed by Borrower to Lender in writing or through inspection pursuant to this Agreement that is marked confidential shall be considered confidential. Lender agrees to use the same degree of care to safeguard and prevent disclosure of such
confidential information as Lender uses with its own confidential information, but in any event no less than a reasonable degree of care. Lender shall not disclose such information to any third party (other than to Lender’s members, partners,
attorneys, governmental regulators, or auditors, or to Lender’s subsidiaries and affiliates and prospective transferees and purchasers of the Loans, all subject to the same confidentiality obligation set forth herein or as required by law,
regulation, subpoena or other order to be disclosed) and shall use such information only for purposes of evaluation of its investment in Borrower and the exercise of Lender’s rights and the enforcement of its remedies under this Agreement and
the other Loan Documents. The obligations of confidentiality shall not apply to any information that (a) was known to the public prior to disclosure by Borrower under this Agreement, (b) becomes known to the public through no fault of
Lender, (c) is disclosed to Lender by a third party having a legal right to make such disclosure, or (d) is independently developed by Lender. Notwithstanding the foregoing, Lender’s agreement of confidentiality shall not apply if
Lender has acquired indefeasible title to any Collateral or in connection with any enforcement or exercise of Lender’s rights and remedies under this Agreement following an Event of Default, including the enforcement of Lender’s security
interest in the Collateral. 
 15. CHOICE OF LAW AND VENUE; JURY TRIAL WAIVER. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED AND
