accordance with GAAP, (iii) liens securing indebtedness permitted under the Closing Documents, (iv) landlords’, operators’, carriers’, warehousemen’s, repairmen’s, mechanics’, materialmen’s, or other like
liens that do not secure the Obligations, in each case only to the extent arising in the ordinary course of business and only to the extent securing obligations that are not delinquent for more than sixty (60) days or that are being contested
in good faith by appropriate proceedings, (v) deposits of cash, letters of credit, or securities to secure the performance of bids, trade contracts (other than for borrowed money), leases, statutory obligations, surety and appeal bonds,

instead paid or advanced by the Secured Party, including without limitation, all taxes, liens, securities interests, encumbrances or other claims at any time levied or placed on the Collateral to the extent that such taxes, liens security interests,
encumbrances or other claims have become delinquent and Debtor has failed to reasonably dispute such taxes, liens security interests, encumbrances or other claims, (ii) all reasonable and customary costs and expenses incurred to correct any
default or enforce any provision of this Agreement, or in gaining possession of, maintaining, handling, preserving, storing, shipping, selling, preparing for sale or advertising to sell all or any part of the Collateral, irrespective of whether a

2.    Construction. Unless the context of this Agreement clearly requires otherwise, references to the
plural include the singular and vice versa, to the part include the whole, “including” is not limiting, and “or” has the inclusive meaning represented by the phrase “and/or.” The words “hereof,”
“herein,” “hereby,” “hereunder,” and similar terms in this Agreement refer to this Agreement as a whole and not to any particular provision of this Agreement. Section references are to this Agreement, unless otherwise
specified. 
 3.    Creation of Security Interest. 

3.1    Grant of Security Interest. In order to secure Debtor’s timely payment of the Obligations and timely
performance of each and all of its covenants and obligations under this Agreement and any other document, instrument or agreement executed by Debtor or delivered by Debtor to the Secured Party in connection with the Obligations, Debtor hereby
unconditionally and irrevocably grants, pledges and hypothecates to the Secured Party a continuing first-priority security interest in and to, a lien upon, assignment of, and right of set-off against, all
presently existing and hereafter acquired or arising Collateral; provided, however, that while a Permitted Lien that is designated “First-Priority” on Exhibit 3 remains in effect on its specified Collateral, the
Secured Party shall instead hold a second or lesser priority (as the case may be) security interest in and to, a lien upon, assignment of, and right of set-off against, such Collateral. The forgoing security
interest shall attach to all Collateral without further act on the part of the Secured Party or Debtor. 

3.2    Rights as to Inventory. Unless an Event of Default under this Agreement is continuing, Debtor may, subject
to the provisions hereof and consistent herewith, sell its inventory and enter into licenses with respect to its property, but in each case only in the ordinary course of Debtor’s business. A sale of inventory in Debtor’s ordinary course
of business does not include an exchange or a transfer in partial or total satisfaction of a debt owing by Debtor, nor does it include an exchange for less than the lower of cost or fair market value. Unless an Event of Default under this Agreement
is continuing, Debtor may also use and consume any raw materials or supplies, the use and consumption of which are necessary to carry on the business of Debtor. 

 4.    Insurance. 

4.1    General. Debtor shall, at its expense, keep its business and assets (including the Collateral to the extent
appropriate), and the business and assets of any subsidiary, insured as provided in the NPA. All insurers and insurance coverage shall be reasonably acceptable to the Secured Party. If Debtor at any time fails to obtain or maintain any insurance as
required under this Agreement, the Secured Party may (but shall not be obligated to) obtain insurance comparable in cost and with coverage in such amounts and types as the insurance coverage required to be maintained by Debtor pursuant hereto,
including if it so chooses “single interest insurance,” which will cover the Secured Party’s interest in the Collateral for its benefit. If any such insurance is obtained by the Secured Party, the cost thereof shall constitute Secured
Party Expenses. 
 4.2    Insurance Reports. Upon reasonable request of the Secured Party, Debtor shall furnish
to the Secured Party reports or certificates on each existing policy of insurance showing such information as the Secured Party may reasonably request, including the following: (i) the name of the insurer, (ii) the risks insured,
(iii) the amount of the policy, (iv) the property insured, (v) the then-current value on the basis of which insurance has been obtained and the manner of determining that value and (vi) the expiration date of the policy. 

5.    Filings; Further Assurances. 

5.1    General. The Secured Party is authorized to file a UCC-1 Financing
Statement with the Secretary of State of the State of Florida evidencing the Secured Party’s security interest in the Collateral. Debtor also authorizes the filing by the Secured Party of such other UCC financing statements, continuation
financing statements, fixture filings, security agreements, mortgages, deeds of trust, chattel mortgages, assignments, motor vehicle lien acknowledgments and other documents as the Secured Party may reasonably require in order to perfect, maintain,
protect or enforce its security interest in the Collateral or any portion thereof and in order to fully consummate all of the transactions contemplated under this Agreement. Subject to the foregoing, if so requested by the Secured Party at any time
hereafter, Debtor shall promptly execute and deliver to the Secured Party such fixture filings, security agreements, mortgages, deeds of trust, chattel mortgages, assignments, motor vehicle lien acknowledgments, and such other documents as the
Secured Party may reasonably require from Debtor in order to perfect, maintain, protect or enforce its rights under this Agreement. Debtor hereby irrevocably constitutes and appoints the Secured Party as Debtor’s true and lawful attorney with
power, upon Debtor’s failure or refusal to promptly comply with its obligations in this Section 5.1, to sign the name of Debtor on any of the above-described documents or on any other similar documents which need to be executed, recorded
or filed in order to perfect, maintain, protect or enforce the Secured Party’s security interest in the Collateral. Debtor’s appointment of the Secured Party as Debtor’s true and lawful attorney shall be solely for the purpose
provided for in the preceding sentence and for no other purpose. Debtor shall promptly pay any filing fees imposed in connection with the filing of any document authorized or required by this Section. If any such filing fees are incurred by the
Secured Party, they shall constitute Secured Party Expenses. 
 5.2    Additional Matters. Without limiting the
generality of Section 5.1, Debtor shall (i) at the reasonable written request of the Secured Party, appear in and defend any action or 

 
proceeding which is reasonably expected to have a material and adverse effect with respect to Debtor’s title to, or the security interest of the Secured Party in, the Collateral and
(ii) promptly furnish to the Secured Party such reports in connection with the Collateral as are required by the NPA. 

6.    Representations, Warranties and Agreements. Debtor represents, warrants and agrees as follows:

 6.1    No Other Encumbrances; First-Priority Lien. Debtor has good and marketable title to the Collateral,
free and clear of any liens, claims, encumbrances and rights of any kind except the Permitted Liens or as otherwise approved in writing by the Secured Party. 

6.2    Right to Inspect the Collateral. The Secured Party shall have the right, during Debtor’s usual business
hours and upon reasonable advance notice, to inspect and examine the Collateral. Debtor shall reimburse the Secured Party for all commercially reasonable costs and expenses incurred by it in connection with one inspection per year plus any other
inspections that are made during the year when an Event of Default is continuing, with Secured Party to bear the costs and expenses of any additional inspections. 

6.3    Title to Motor Vehicles. Upon the Secured Party’s reasonable request pursuant to Section 5(ee) of the
NPA, the Borrower shall as promptly as is commercially reasonable (i) cause a lien on each of its motor vehicles that is not listed on the attached Exhibit 2 and has no existing lien against it to be recorded with the appropriate state
bureau or department of motor vehicles in such manner as is appropriate to perfect the Secured Party’s first-priority security interest therein under applicable law and (ii) cause title documentation for those motor vehicles showing such
lien to be delivered to the Secured Party. 
 6.4    Maintenance of Motor Vehicles and Equipment. Debtor shall
keep and maintain its motor vehicles and equipment (to the extent not listed on the attached Exhibit 2) in good operating condition and repair (ordinary wear and tear excepted) so that the value and operating efficiency thereof shall at all
times be maintained and preserved consistent with reasonable business practices. 
 6.5    Negative Covenants.
Debtor shall not (i) sell, lease or otherwise dispose of, or relocate or transfer, any of the Collateral, except as provided in Section 3.2 or dispositions of any Collateral that is worn out, obsolete or no longer necessary in the business
of Debtor (provided that Collateral may be transported to and from and located at multiple job sites and vendors for refurbishment or repair in the ordinary course of business), (ii) allow any liens on the Collateral except the Permitted Liens or
(iii) change its name or add any new fictitious name without providing the Secured Party with at least fifteen (15) days prior written notice thereof. 

6.6    Relocation of Principal Place of Business. The principal place of business of Debtor, and the addresses at
which the Collateral is located, are shown on the attached Exhibit 4. Debtor shall not, without at least thirty (30) days prior written notice to the Secured Party, relocate such principal place of business or the Collateral (subject to
Section 6.5 above), with no relocation being permitted outside the United States in any event. 

 6.7    Further Information. Debtor shall promptly supply the Secured
Party with such information concerning Debtor’s business as the Secured Party may reasonably request from time-to-time, and shall within five (5) business days
of obtaining knowledge thereof, notify the Secured Party of any event which constitutes an Event of Default. 

6.8    Solvency. Debtor is now and shall be at all times hereafter able to pay its debts (including trade debts) as
they mature. 
 6.9    Secured Party Expenses. Debtor shall, within fifteen (15) business days of written
demand from the Secured Party accompanied by adequate documentation, reimburse the Secured Party for all sums expended by it which constitute Secured Party Expenses. In the event that Debtor does not pay any Secured Party Expenses payable to a third
party within fifteen (15) business days after notice thereof, then the Secured Party may immediately and without further notice pay such Secured Party Expenses on Debtor’s behalf. All Secured Party Expenses that are not paid by Debtor in a
timely manner shall become a part of the Obligations and bear interest at the Rate specified in the Note until repaid 

6.10    Commercial Tort Claims. Debtor has no pending commercial tort claim (as a plaintiff) against any individual
or entity (a “Commercial Claim”) except as listed on the attached Exhibit 5. Debtor shall promptly deliver to the Secured Party notice of any Commercial Claim that Debtor may bring against any individual or entity,
together with such information with respect thereto as the Secured Party may reasonably request. Within ten (10) business days after a written request by the Secured Party, Debtor shall grant the Secured Party a security interest in any pending
Commercial Claim to the extent such security interest is permitted by applicable law. 
 6.11    Reliance by the
Secured Party; Representations Cumulative. Each representation, warranty and agreement contained in this Agreement shall be conclusively presumed to have been relied on by the Secured Party regardless of any investigation made or information
possessed thereby. The representations, warranties and agreements set forth herein shall be cumulative and in addition to any and all other representations, warranties and agreements of Debtor that are set forth in the Closing Documents or any other
documents created after the Closing Date and signed by Debtor. 
 6.12    Article 9 Override Property.
Debtor’s “Article 9 Override Property” (as defined in Exhibit 2) does not constitute a material portion of the aggregate value of the Borrowers’ (as defined in the NPA) tangible and intangible personal property assets
taken as a whole. 
 7.    Events of Default. The occurrence of any Event of Default under the Note, after
the expiration of any applicable grace or cure period, shall constitute an “Event of Default” by Debtor under this Agreement. At any time during the continuance of an Event of Default, Debtor shall, at its expense, upon the Secured
Party’s reasonable request, have an independent appraiser satisfactory to the Secured Party determine the cash value or replacement cost (as applicable) of the Collateral. 

 8.    Rights and Remedies. 

8.1    Rights and Remedies of the Secured Party. 

(a)    During the continuance of an Event of Default, without notice of election and without demand, the Secured Party may
cause any one or more of the following to occur, all of which are hereby authorized by Debtor: 
 (i)    The Secured
Party may make such payments and take such other actions as it reasonably considers necessary to protect, maintain, perfect or enforce its security interest in the Collateral. Debtor agrees to promptly assemble and make available the Collateral if
the Secured Party so requires. Debtor authorizes the Secured Party to enter the premises where the Collateral is located, take and maintain possession of the Collateral (or any part thereof), and pay, purchase, contest or compromise any encumbrance,
claim, right or lien which, in the reasonable opinion of the Secured Party, appears to be prior or superior to its security interest in violation of this Agreement, and to pay all reasonable expenses incurred in connection therewith. 

(ii)    The Secured Party shall be automatically deemed to be granted a license or other appropriate right to use,
without charge or other obligation, Debtor’s labels, patents, copyrights, rights of use of any name, trade secrets, trade names, trademarks, service marks and advertising matter, and any other property of a similar nature as it pertains to the
Collateral, in completing production of, advertising for sale, and selling any Collateral. 
 (iii)    The Secured
Party may ship, reclaim, recover, store, finish, maintain, repair, prepare for sale, advertise for sale and sell (in the manner provided for herein) the Collateral. 

(iv)    The Secured Party may 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 Debtor’s premises) as is commercially reasonable (it not being necessary that the Collateral be present at any such sale). 

(v)    The Secured Party shall be entitled to give notice of the disposition of the Collateral as follows: (A) the
Secured Party shall give Debtor a notice in writing of the time and place of public sale, or, if the sale is a private sale or some other disposition other than a public sale is to be made of the Collateral, the time on or after which the private
sale or other disposition is to be made, (B) the notice shall be personally delivered or mailed, postage prepaid, to Debtor at least ten (10) days before the date fixed for the sale, or at least ten (10) days before the date on which
the private sale or other disposition is to be made, unless the Collateral is perishable or threatens to decline speedily in value, in which case the Secured Party shall use commercially reasonable efforts to provide such notice to Debtor as far in
advance of such disposition as is practicable, and (C) if the sale is to be a public sale, the Secured Party shall also give notice of the time and place by publishing a notice at least twice (the first at least twenty (20) days before the
date of the sale) in a newspaper of general circulation, if one exists, in the county in which the sale is to be held. 

(vi)    The Secured Party may purchase all or any portion of the Collateral at any public sale by credit bid or other
appropriate payment therefor. 

 (vii)    To the extent permitted by applicable law, the Secured Party shall
have the following rights and remedies regarding the appointment of a receiver: (A) the Secured Party may have a receiver appointed as a matter of right, (B) the receiver may be an employee of the Secured Party and may serve without bond,
and (C) all fees and expenses of the receiver and his or her attorney shall be Secured Party Expenses. 

(viii)    The Secured Party, either itself or through a receiver, may collect the payments, rents, income, and revenues
from the Collateral. The Secured Party may at any time, in its reasonable discretion, transfer any Collateral into its own name or that of its nominee(s) and receive the payments, rents, income, and revenues therefrom and hold the same as security
for the Obligations or apply them to payment of the Obligations in such order of preference as the Secured Party may determine. Insofar as any Collateral consists of accounts, general intangibles (including all amounts due to Debtor from a factor),
loans receivable, insurance policies, instruments, chattel paper, choses in action, or similar property, the Secured Party may demand, collect, issue receipts for, settle, compromise, adjust, sue for, foreclose, or otherwise realize on the
Collateral to such extent as the Secured Party may determine (in its reasonable discretion). For these purposes, the Secured Party may, on behalf of and in the name of Debtor, (A) receive, open and dispose of mail addressed to Debtor and remove
therefrom any payments and/or proceeds constituting Collateral, (B) change any address to which mail and payments regarding the Collateral are to be sent, and (C) endorse or sign Debtor’s name on all notes, checks, drafts, money
orders, documents of title, instruments and items pertaining to the payment, shipment, or storage of any Collateral. To facilitate collection, the Secured Party may notify (or require Debtor to notify) all account debtors and obligors on any
Collateral to forward all payments and proceeds to a post office box under the Secured Party’s exclusive control. 

(ix)    The Secured Party may enforce its security interest under this Agreement pursuant to the UCC and/or any other
applicable law. 
 (b)    The Secured Party may deduct from the proceeds of any sale of the Collateral all Secured Party
Expenses incurred in connection with the enforcement and exercise of any of the rights and remedies of the Secured Party provided for herein, irrespective of whether suit is commenced. If such deduction does not occur (in the Secured Party’s
reasonable discretion), upon demand, Debtor shall pay all of such Secured Party Expenses. Any deficiency which exists after disposition of the Collateral as provided herein shall be paid immediately by Debtor, and any excess that exists shall be
returned, without interest and subject to the rights of third parties, to Debtor by the Secured Party; provided, however, that if any excess exists at a time when any of the Obligations remain outstanding, such excess shall instead
remain as part of the Collateral and continue to be subject to the security interest in Section 3.1 above until such time as all of the Obligations have been fully satisfied or otherwise terminated. 

8.2    Rights and Remedies Cumulative. The rights and remedies of the Secured Party under this Agreement and any
other agreements and documents delivered or executed by Debtor in connection with the Obligations shall be cumulative. The Secured Party shall also have all other rights and remedies not inconsistent herewith as are provided under applicable law, or
in equity. No exercise by the Secured Party of any one right or remedy shall be deemed an election. 

 9.    Additional Waivers. 

(a)    The Secured Party shall not in any way or manner be liable or responsible for (i) the safekeeping of the
Collateral, (ii) any loss or damage to the Collateral occurring or arising in any manner or fashion from any cause, (iii) any diminution in the value of the Collateral or (iv) any act or default of any carrier, warehouseman, bailee,
forwarding agency or other individual or entity whomsoever, except to the extent that such loss, damage, liability, cost or expense has resulted from the gross negligence or willful misconduct of the Secured Party or its Affiliates. If the Secured
Party at any time has possession of any Collateral, whether before or after an Event of Default, the Secured Party shall be deemed to have exercised reasonable care in the custody and preservation of the Collateral if it takes such action for that
purpose as Debtor shall request or as the Secured Party, in its reasonable discretion, shall deem appropriate under the circumstances, but failure to honor any request by Debtor shall not of itself be deemed to be a failure to exercise reasonable
care. The Secured Party shall not be required to take any steps necessary to preserve any rights in the Collateral against prior parties, nor to protect, preserve, or maintain any security interest given to secure the Obligations. 

(b)    In the event that the Secured Party seeks to take possession of all or any part of the Collateral by judicial
process, Debtor hereby irrevocably waives any bonds and any surety or security relating thereto that may be required by applicable law as an incident to such possession, and waives any demand for possession prior to the commencement of any such
judicial process. 
 10.    Notices. All notices or demands by either party relating to this Agreement
shall be made in writing as provided in the NPA. Each party shall promptly provide written notice to the other party of any change in address. 

11.    Choice of Law. The validity of this Agreement, its construction, interpretation and enforcement, and
the rights of the parties hereunder and concerning the Collateral, shall be determined under, governed by, and construed in accordance with the laws of California as applied to contracts made and to be fully performed in such state, without regard
to the conflicts of laws provisions thereof, except to the extent that the validity, perfection or enforcement of a security interest hereunder in respect of any Collateral is governed by the laws of Florida or some other state, in which case such
laws shall govern. 
 12.    Waiver of Jury Trial. THE PARTIES EACH WAIVE, TO THE EXTENT PERMITTED BY
LAW, ANY RIGHT TO TRIAL BY JURY IN ANY ACTION OR PROCEEDING RELATING TO THIS AGREEMENT. 
 13.    General
Provisions. 
 13.1    Effectiveness. This Agreement shall be binding and deemed effective when executed
by Debtor and the Secured Party. 
 13.2    Successors and Assigns. This Agreement shall bind and inure to the
benefit of the successors and permitted endorsees, transferees and assigns of the Secured Party. Debtor shall not assign this Agreement or any rights or obligations hereunder, and any such assignment shall be absolutely void. 

 13.3    Section Headings. Section headings are for convenience only.

 13.4    Interpretation. No uncertainty or ambiguity herein shall be construed or resolved against the Secured
Party or Debtor, whether under any rule of construction or otherwise. This Agreement shall be construed and interpreted according to the ordinary meaning of the words used so as to fairly accomplish the purposes and intentions of the parties. 

13.5    Severability of Provisions. Each provision of this Agreement shall be severable from every other provision
of this Agreement for the purpose of determining the legal enforceability of any specific provision. 

13.6    Entire Agreement; Amendments. This Agreement and the documents referenced herein contain the entire
understanding of the parties with respect to the subject matter covered herein and supersede all prior agreements, negotiations and understandings, written or oral, with respect to such subject matter. No provision of this Agreement shall be waived
or amended other than by an instrument in writing signed by Debtor and the Secured Party. 
 13.7    Good Faith.
The parties intend and agree that their respective rights, duties, powers, liabilities and obligations shall be performed, carried out, discharged and exercised reasonably and in good faith. 

13.8    Waiver and Consent. No delay or omission on the part of the Secured Party in exercising any right shall
operate as a waiver of such right or any other right. A waiver by the Secured Party of a provision of this Agreement shall not prejudice or constitute a waiver of the Secured Party’s right otherwise to demand strict compliance with that
provision or any other provision of this Agreement. No prior waiver by the Secured Party, nor any course of dealing between the Secured Party and Debtor, shall constitute a subsequent waiver of any of the Secured Party’s rights or of any of
Debtor’s obligations. Whenever the consent of the Secured Party is required under this Agreement, the granting of such consent by the Secured Party in any instance shall not constitute continuing consent to subsequent instances where such
consent is required and in all cases such consent may be granted or withheld in the sole discretion of the Secured Party. 

13.9    Counterparts. This Agreement may be executed in any number of counterparts, each of which, when executed
and delivered, shall be deemed to be an original, and all of which, when taken together, shall constitute but one and the same agreement. 

13.10    Termination. Upon full satisfaction or other termination of the Obligations (i) the Secured Party
shall release and return to Debtor all of the Collateral and any and all certificates and other documentation representing or relating to the Collateral and (ii) the security interests provided for under this Agreement shall be terminated and
of no further force and effect. At Debtor’s expense, the Secured Party shall take all actions reasonably requested by Debtor in connection with the foregoing. 

13.11    Attorney’s Fees.    If a party to this Agreement shall bring any
action for relief against the other party arising out of or in connection with this Agreement, in addition to all other remedies to which the prevailing party may be entitled, the losing party shall be

 
required to pay to the prevailing party a reasonable sum for attorney’s fees and costs incurred in bringing or defending such action and/or enforcing any judgment granted therein, all of
which shall be deemed to have accrued upon the commencement of such action and shall be paid whether or not such action is prosecuted to judgment. Any judgment or order entered in such action shall contain a specific provision providing for the
recovery of attorney’s fees and costs incurred in enforcing such judgment. For the purposes of this Section, attorney’s fees shall include, without limitation, fees incurred with respect to the following: (i) post-judgment motions,
(ii) contempt proceedings, (iii) garnishment, levy and debtor and third party examinations, (iv) discovery, (v) bankruptcy litigation and (vi) any appellate proceedings. 

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly executed by their respective authorized persons on the date first

applicable party or parties’ consent with respect to any otherwise excluded directly held Article 9 Override Property, thereafter such directly held Article 9 Override Property, (C) Article 9 Override Property to the extent that the
restriction on the Debtor granting a security interest therein is not effective under applicable law, (D) payment intangibles and (E) Article 9 Override Property to the extent that, notwithstanding any provisions contained therein or
related thereto which prohibit assignments thereof, the UCC permits the assignment thereof for collateral purposes, and the assignment thereof is not otherwise precluded by law; 

(b)    any equipment, machinery or other fixed asset which Debtor has or may hereafter acquire with the financing of

lien document applicable thereto without the consent of the secured party thereto, and (ii) such consent has not been obtained. Notwithstanding the foregoing, the Collateral shall include a previously excluded PMSI Lien Asset (i) upon
receipt by Debtor or Secured Party of the other secured party’s consent to Secured Party’s lien thereon, or (ii) upon the release of the underlying purchase money lien held by the financing secured party with respect to such PMSI Lien
Asset; 
 (c)    any equipment, inventory, machinery or other fixed asset which Debtor leases or may hereafter lease
with the financing of another secured party (collectively, the “Capitalized

the terms of the lien document applicable thereto without the consent of the secured party thereto, and (ii) such consent has not been obtained. Notwithstanding the foregoing, the Collateral shall include a previously excluded Capitalized Lease
Lien Asset (i) upon receipt by Debtor or Secured Party of the other secured party’s consent to Secured Party’s lien thereon, or (ii) upon the release of the underlying lien held by the financing secured party with respect to such

 (d)    any United States
trademark or service mark application filed on the basis of Debtor’s intent-to-use such mark, in each case, unless and until evidence of the use of such trademark
or service mark in interstate commerce is submitted to, and accepted by, the United States Patent and Trademark Office, provided, that, to the extent such application is excluded from the Collateral, then upon the submission of evidence of use of
such trademark or service mark to, and acceptance thereof by, the United States Patent and Trademark Office, such trademark or service mark application shall automatically be included in the Collateral, without further action on any party’s
part; 
 (e)    any proceeds, payments or other rights under insurance contracts covering (x) the acts (or non-acts) of directors, employees or officers of Debtor its subsidiaries; or a parent or other Affiliate thereof or (y) worker’s compensation;

Agreement with the Secured Party as security for Debtor’s Obligations (as defined below). 
 Agreements 

NOW, THEREFORE, in consideration of their respective promises contained herein and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereby agree as follows: 
 1.    Definitions.
Terms used but not otherwise defined in this Agreement that are defined in the Uniform Commercial Code as adopted in the State of Texas (“UCC”) (such as “account,” “chattel paper,” “deposit

covering the foregoing or any portion thereof; provided, however, that notwithstanding anything to the contrary contained in this Agreement, the Collateral does not include

section 6903(5), as such section may be amended from time-to-time, or under any regulations thereunder. 

“Debtor’s Books” means all of Debtor’s books and records, including, but not limited to, all records, ledgers and
computer programs, disk or tape files, printouts, electronic media, and any other computer-prepared information (including, but not limited to, any computer-readable memory) indicating, summarizing or evidencing the Collateral.

accordance with GAAP, (iii) liens securing indebtedness permitted under the Closing Documents, (iv) landlords’, operators’, carriers’, warehousemen’s, repairmen’s, mechanics’, materialmen’s, or other like
liens that do not secure the Obligations, in each case only to the extent arising in the ordinary course of business and only to the extent securing obligations that are not delinquent for more than sixty (60) days or that are being contested
in good faith by appropriate proceedings, (v) deposits of cash, letters of credit, or securities to secure the performance of bids, trade contracts (other than for borrowed money), leases, statutory obligations, surety and appeal bonds,

insurance reasonably acceptable to the Secured Party, (ix) pledges or deposits in connection with workers’ compensation, unemployment insurance and other social security legislations,
and (x) all liens set forth in the Title Policy (as defined in the NPA). 
 “Secured Party Expenses” means
(i) all costs or expenses required to be paid by Debtor under this Agreement that are instead paid or advanced by the Secured Party, including without limitation, all taxes, liens, securities interests, encumbrances or other claims at any time
levied or placed on the Collateral to the extent that such taxes, liens security interests, encumbrances or other claims have become delinquent and Debtor has failed to reasonably dispute such taxes, liens security interests, encumbrances or other
claims, (ii) all reasonable and customary costs and expenses incurred to correct any default or enforce any provision of this Agreement, or in gaining possession of, maintaining, handling, preserving, storing, shipping, selling, preparing for
sale or advertising to sell all or any part of the Collateral, irrespective of whether a sale is consummated, and (iii) all reasonable costs and expenses (including reasonable attorney’s fees) incurred by the Secured Party in enforcing or
defending this Agreement, irrespective of whether suit is brought. 
 2.    Construction. Unless the
context of this Agreement clearly requires otherwise, references to the plural include the singular and vice versa, to the part include the whole, “including” is not limiting, and “or” has the inclusive meaning represented by the
phrase “and/or.” The words “hereof,” “herein,” “hereby,” “hereunder,” and similar terms in this Agreement refer to this Agreement as a whole and not to any particular provision of this Agreement.
Section references are to this Agreement, unless otherwise specified. 
 3.    Creation of Security
Interest. 
 3.1    Grant of Security Interest. In order to secure Debtor’s timely payment of the
Obligations and timely performance of each and all of its covenants and obligations under this Agreement and any other document, instrument or agreement executed by Debtor or delivered by Debtor to the Secured Party in connection with the
Obligations, Debtor hereby unconditionally and irrevocably grants, pledges and hypothecates to the Secured Party a continuing first-priority security interest in and to, a lien upon, assignment of, and right of
set-off against, all presently existing and hereafter acquired or arising Collateral; provided, however, that while a Permitted Lien that is designated “First-Priority” on Exhibit 3
remains in effect on its specified Collateral, the Secured Party shall instead hold a second or lesser priority (as the case may be) security interest in and to, a lien upon, assignment of, and right of
set-off against, such Collateral. The forgoing security interest shall attach to all Collateral without further act on the part of the Secured Party or Debtor. 

3.2    Rights as to Inventory. Unless an Event of Default under this Agreement is continuing, Debtor may, subject
to the provisions hereof and consistent herewith, sell its inventory and enter into licenses with respect to its property, but in each case only in the ordinary course of Debtor’s business. A sale of inventory in Debtor’s ordinary course
of business does not include an exchange or a transfer in partial or total satisfaction of a debt owing by Debtor, nor does it include an exchange for less than the lower of cost or fair market value. 

Unless an Event of Default under this Agreement is continuing, Debtor may also use and consume any raw materials or supplies, the use and consumption of which
are necessary to carry on the business of Debtor. 

 4.    Insurance. 

4.1    General.    Debtor shall, at its expense, keep its business and assets (including the
Collateral to the extent appropriate), and the business and assets of any subsidiary, insured as provided in the NPA. All insurers and insurance coverage shall be reasonably acceptable to the Secured Party. If Debtor at any time fails to obtain or
maintain any insurance as required under this Agreement, the Secured Party may (but shall not be obligated to) obtain insurance comparable in cost and with coverage in such amounts and types as the insurance coverage required to be maintained by
Debtor pursuant hereto, including if it so chooses “single interest insurance,” which will cover the Secured Party’s interest in the Collateral for its benefit. If any such insurance is obtained by the Secured Party, the cost thereof
shall constitute Secured Party Expenses. 
 4.2    Insurance Reports. Upon reasonable request of the Secured
Party, Debtor shall furnish to the Secured Party reports or certificates on each existing policy of insurance showing such information as the Secured Party may reasonably request, including the following: (i) the name of the insurer,
(ii) the risks insured, (iii) the amount of the policy, (iv) the property insured, (v) the then-current value on the basis of which insurance has been obtained and the manner of determining that value and (vi) the expiration
date of the policy. 
 5.    Filings; Further Assurances. 

5.1    General. The Secured Party is authorized to file a UCC-1 Financing
Statement with the Secretary of State of the State of Texas evidencing the Secured Party’s security interest in the Collateral. Debtor also authorizes the filing by the Secured Party of such other UCC financing statements, continuation
financing statements, fixture filings, security agreements, mortgages, deeds of trust, chattel mortgages, assignments, motor vehicle lien acknowledgments and other documents as the Secured Party may reasonably require in order to perfect, maintain,
protect or enforce its security interest in the Collateral or any portion thereof and in order to fully consummate all of the transactions contemplated under this Agreement. Subject to the foregoing, if so requested by the Secured Party at any time
hereafter, Debtor shall promptly execute and deliver to the Secured Party such fixture filings, security agreements, mortgages, deeds of trust, chattel mortgages, assignments, motor vehicle lien acknowledgments, and such other documents as the
Secured Party may reasonably require from Debtor in order to perfect, maintain, protect or enforce its rights under this Agreement. Debtor hereby irrevocably constitutes and appoints the Secured Party as Debtor’s true and lawful attorney with
power, upon Debtor’s failure or refusal to promptly comply with its obligations in this Section 5.1, to sign the name of Debtor on any of the above-described documents or on any other similar documents which need to be executed, recorded
or filed in order to perfect, maintain, protect or enforce the Secured Party’s security interest in the Collateral. Debtor’s appointment of the Secured Party as Debtor’s true and lawful attorney shall be solely for the purpose
provided for in the preceding sentence and for no other purpose. Debtor shall promptly pay any filing fees imposed in connection with the filing of any document authorized or required by this Section. If any such filing fees are incurred by the
Secured Party, they shall constitute Secured Party Expenses. 
 5.2    Additional Matters. Without limiting the
generality of Section 5.1, Debtor shall (i) at the reasonable written request of the Secured Party, appear in and defend any action or 

 
proceeding which is reasonably expected to have a material and adverse effect with respect to Debtor’s title to, or the security interest of the Secured Party in, the Collateral and
(ii) promptly furnish to the Secured Party such reports in connection with the Collateral as are required by the NPA. 

6.    Representations, Warranties and Agreements. Debtor represents, warrants and agrees as follows:

 6.1    No Other Encumbrances; First-Priority Lien. Debtor has good and marketable title to the Collateral,
free and clear of any liens, claims, encumbrances and rights of any kind except the Permitted Liens or as otherwise approved in writing by the Secured Party. 

6.2    Right to Inspect the Collateral. The Secured Party shall have the right, during Debtor’s usual business
hours and upon reasonable advance notice, to inspect and examine the Collateral. Debtor shall reimburse the Secured Party for all commercially reasonable costs and expenses incurred by it in connection with one inspection per year plus any other
inspections that are made during the year when an Event of Default is continuing, with Secured Party to bear the costs and expenses of any additional inspections. 

6.3    Title to Motor Vehicles. Upon the Secured Party’s reasonable request pursuant to Section 5(ee) of the
NPA, the Borrower shall as promptly as is commercially reasonable (i) cause a lien on each of its motor vehicles that is not listed on the attached Exhibit 2 and has no existing lien against it to be recorded with the appropriate state
bureau or department of motor vehicles in such manner as is appropriate to perfect the Secured Party’s first-priority security interest therein under applicable law and (ii) cause title documentation for those motor vehicles showing such
lien to be delivered to the Secured Party. 
 6.4    Maintenance of Motor Vehicles and Equipment. Debtor shall
keep and maintain its motor vehicles and equipment (to the extent not listed on the attached Exhibit 2) in good operating condition and repair (ordinary wear and tear excepted) so that the value and operating efficiency thereof shall at all
times be maintained and preserved consistent with reasonable business practices. 
 6.5    Negative Covenants.
Debtor shall not (i) sell, lease or otherwise dispose of, or relocate or transfer, any of the Collateral, except as provided in Section 3.2 or dispositions of any Collateral that is worn out, obsolete or no longer necessary in the business
of Debtor (provided that Collateral may be transported to and from and located at multiple job sites and vendors for refurbishment or repair in the ordinary course of business), (ii) allow any liens on the Collateral except the Permitted Liens or
(iii) change its name or add any new fictitious name without providing the Secured Party with at least fifteen (15) days prior written notice thereof. 

6.6    Relocation of Principal Place of Business. The principal place of business of Debtor, and the addresses at
which the Collateral is located, are shown on the attached Exhibit 4. Debtor shall not, without at least thirty (30) days prior written notice to the Secured Party, relocate such principal place of business or the Collateral (subject to
Section 6.5 above), with no relocation being permitted outside the United States in any event. 

 6.7    Further Information. Debtor shall promptly supply the Secured
Party with such information concerning Debtor’s business as the Secured Party may reasonably request from time-to-time, and shall within five (5) business days
of obtaining knowledge thereof, notify the Secured Party of any event which constitutes an Event of Default. 

6.8    Solvency. Debtor is now and shall be at all times hereafter able to pay its debts (including trade debts) as
they mature. 
 6.9    Secured Party Expenses. Debtor shall, within fifteen (15) business days of written
demand from the Secured Party accompanied by adequate documentation, reimburse the Secured Party for all sums expended by it which constitute Secured Party Expenses. In the event that Debtor does not pay any Secured Party Expenses payable to a third
party within fifteen (15) business days after notice thereof, then the Secured Party may immediately and without further notice pay such Secured Party Expenses on Debtor’s behalf. All Secured Party Expenses that are not paid by Debtor in a
timely manner shall become a part of the Obligations and bear interest at the Rate specified in the Note until repaid 

6.10    Commercial Tort Claims. Debtor has no pending commercial tort claim (as a plaintiff) against any individual
or entity (a “Commercial Claim”) except as listed on the attached Exhibit 5. Debtor shall promptly deliver to the Secured Party notice of any Commercial Claim that Debtor may bring against any individual or entity,
together with such information with respect thereto as the Secured Party may reasonably request. Within ten (10) business days after a written request by the Secured Party, Debtor shall grant the Secured Party a security interest in any pending
Commercial Claim to the extent such security interest is permitted by applicable law. 
 6.11    Reliance by the
Secured Party; Representations Cumulative. Each representation, warranty and agreement contained in this Agreement shall be conclusively presumed to have been relied on by the Secured Party regardless of any investigation made or information
possessed thereby. The representations, warranties and agreements set forth herein shall be cumulative and in addition to any and all other representations, warranties and agreements of Debtor that are set forth in the Closing Documents or any other
documents created after the Closing Date and signed by Debtor. 
 6.12    Article 9 Override Property.
Debtor’s “Article 9 Override Property” (as defined in Exhibit 2) does not constitute a material portion of the aggregate value of the Borrowers’ (as defined in the NPA) tangible and intangible personal property assets
taken as a whole. 
 7.    Events of Default. The occurrence of any Event of Default under the Note, after
the expiration of any applicable grace or cure period, shall constitute an “Event of Default” by Debtor under this Agreement. At any time during the continuance of an Event of Default, Debtor shall, at its expense, upon the Secured
Party’s reasonable request, have an independent appraiser satisfactory to the Secured Party determine the cash value or replacement cost (as applicable) of the Collateral. 

 8.    Rights and Remedies. 

8.1    Rights and Remedies of the Secured Party. 

(a)    During the continuance of an Event of Default, without notice of election and without demand, the Secured Party may
cause any one or more of the following to occur, all of which are hereby authorized by Debtor: 
 (i)    The Secured
Party may make such payments and take such other actions as it reasonably considers necessary to protect, maintain, perfect or enforce its security interest in the Collateral. Debtor agrees to promptly assemble and make available the Collateral if
the Secured Party so requires. Debtor authorizes the Secured Party to enter the premises where the Collateral is located, take and maintain possession of the Collateral (or any part thereof), and pay, purchase, contest or compromise any encumbrance,
claim, right or lien which, in the reasonable opinion of the Secured Party, appears to be prior or superior to its security interest in violation of this Agreement, and to pay all reasonable expenses incurred in connection therewith. 

(ii)    The Secured Party shall be automatically deemed to be granted a license or other appropriate right to use,
without charge or other obligation, Debtor’s labels, patents, copyrights, rights of use of any name, trade secrets, trade names, trademarks, service marks and advertising matter, and any other property of a similar nature as it pertains to the
Collateral, in completing production of, advertising for sale, and selling any Collateral. 
 (iii)    The Secured
Party may ship, reclaim, recover, store, finish, maintain, repair, prepare for sale, advertise for sale and sell (in the manner provided for herein) the Collateral. 

(iv)    The Secured Party may 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 Debtor’s premises) as is commercially reasonable (it not being necessary that the Collateral be present at any such sale). 

(v)    The Secured Party shall be entitled to give notice of the disposition of the Collateral as follows: (A) the
Secured Party shall give Debtor a notice in writing of the time and place of public sale, or, if the sale is a private sale or some other disposition other than a public sale is to be made of the Collateral, the time on or after which the private
sale or other disposition is to be made, (B) the notice shall be personally delivered or mailed, postage prepaid, to Debtor at least ten (10) days before the date fixed for the sale, or at least ten (10) days before the date on which
the private sale or other disposition is to be made, unless the Collateral is perishable or threatens to decline speedily in value, in which case the Secured Party shall use commercially reasonable efforts to provide such notice to Debtor as far in
advance of such disposition as is practicable, and (C) if the sale is to be a public sale, the Secured Party shall also give notice of the time and place by publishing a notice at least twice (the first at least twenty (20) days before the
date of the sale) in a newspaper of general circulation, if one exists, in the county in which the sale is to be held. 

(vi)    The Secured Party may purchase all or any portion of the Collateral at any public sale by credit bid or other
appropriate payment therefor. 

 (vii)    To the extent permitted by applicable law, the Secured Party shall
have the following rights and remedies regarding the appointment of a receiver: (A) the Secured Party may have a receiver appointed as a matter of right, (B) the receiver may be an employee of the Secured Party and may serve without bond,
and (C) all fees and expenses of the receiver and his or her attorney shall be Secured Party Expenses. 

(viii)    The Secured Party, either itself or through a receiver, may collect the payments, rents, income, and revenues
from the Collateral. The Secured Party may at any time, in its reasonable discretion, transfer any Collateral into its own name or that of its nominee(s) and receive the payments, rents, income, and revenues therefrom and hold the same as security
for the Obligations or apply them to payment of the Obligations in such order of preference as the Secured Party may determine. Insofar as any Collateral consists of accounts, general intangibles (including all amounts due to Debtor from a factor),
loans receivable, insurance policies, instruments, chattel paper, choses in action, or similar property, the Secured Party may demand, collect, issue receipts for, settle, compromise, adjust, sue for, foreclose, or otherwise realize on the
Collateral to such extent as the Secured Party may determine (in its reasonable discretion). For these purposes, the Secured Party may, on behalf of and in the name of Debtor, (A) receive, open and dispose of mail addressed to Debtor and remove
therefrom any payments and/or proceeds constituting Collateral, (B) change any address to which mail and payments regarding the Collateral are to be sent, and (C) endorse or sign Debtor’s name on all notes, checks, drafts, money
orders, documents of title, instruments and items pertaining to the payment, shipment, or storage of any Collateral. To facilitate collection, the Secured Party may notify (or require Debtor to notify) all account debtors and obligors on any
Collateral to forward all payments and proceeds to a post office box under the Secured Party’s exclusive control. 

(ix)    The Secured Party may enforce its security interest under this Agreement pursuant to the UCC and/or any other
applicable law. 
 (b)    The Secured Party may deduct from the proceeds of any sale of the Collateral all Secured Party
Expenses incurred in connection with the enforcement and exercise of any of the rights and remedies of the Secured Party provided for herein, irrespective of whether suit is commenced. If such deduction does not occur (in the Secured Party’s
reasonable discretion), upon demand, Debtor shall pay all of such Secured Party Expenses. Any deficiency which exists after disposition of the Collateral as provided herein shall be paid immediately by Debtor, and any excess that exists shall be
returned, without interest and subject to the rights of third parties, to Debtor by the Secured Party; provided, however, that if any excess exists at a time when any of the Obligations remain outstanding, such excess shall instead
remain as part of the Collateral and continue to be subject to the security interest in Section 3.1 above until such time as all of the Obligations have been fully satisfied or otherwise terminated. 

8.2    Rights and Remedies Cumulative. The rights and remedies of the Secured Party under this Agreement and any
other agreements and documents delivered or executed by Debtor in connection with the Obligations shall be cumulative. The Secured Party shall also have all other rights and remedies not inconsistent herewith as are provided under applicable law, or
in equity. No exercise by the Secured Party of any one right or remedy shall be deemed an election. 

 9.    Additional Waivers. 

(a)    The Secured Party shall not in any way or manner be liable or responsible for (i) the safekeeping of the
Collateral, (ii) any loss or damage to the Collateral occurring or arising in any manner or fashion from any cause, (iii) any diminution in the value of the Collateral or (iv) any act or default of any carrier, warehouseman, bailee,
forwarding agency or other individual or entity whomsoever, except to the extent that such loss, damage, liability, cost or expense has resulted from the gross negligence or willful misconduct of the Secured Party or its Affiliates. If the Secured
Party at any time has possession of any Collateral, whether before or after an Event of Default, the Secured Party shall be deemed to have exercised reasonable care in the custody and preservation of the Collateral if it takes such action for that
purpose as Debtor shall request or as the Secured Party, in its reasonable discretion, shall deem appropriate under the circumstances, but failure to honor any request by Debtor shall not of itself be deemed to be a failure to exercise reasonable
care. The Secured Party shall not be required to take any steps necessary to preserve any rights in the Collateral against prior parties, nor to protect, preserve, or maintain any security interest given to secure the Obligations. 

(b)    In the event that the Secured Party seeks to take possession of all or any part of the Collateral by judicial
process, Debtor hereby irrevocably waives any bonds and any surety or security relating thereto that may be required by applicable law as an incident to such possession, and waives any demand for possession prior to the commencement of any such
judicial process. 
 10.    Notices. All notices or demands by either party relating to this Agreement
shall be made in writing as provided in the NPA. Each party shall promptly provide written notice to the other party of any change in address. 

11.    Choice of Law. The validity of this Agreement, its construction, interpretation and enforcement, and
the rights of the parties hereunder and concerning the Collateral, shall be determined under, governed by, and construed in accordance with the laws of California as applied to contracts made and to be fully performed in such state, without regard
to the conflicts of laws provisions thereof, except to the extent that the validity, perfection or enforcement of a security interest hereunder in respect of any Collateral is governed by the laws of Texas or some other state, in which case such
laws shall govern. 
 12.    Waiver of Jury Trial. THE PARTIES EACH WAIVE, TO THE EXTENT PERMITTED BY
LAW, ANY RIGHT TO TRIAL BY JURY IN ANY ACTION OR PROCEEDING RELATING TO THIS AGREEMENT. 
 13.    General
Provisions. 
 13.1    Effectiveness. This Agreement shall be binding and deemed effective when executed
by Debtor and the Secured Party. 
 13.2    Successors and Assigns. This Agreement shall bind and inure to the
benefit of the successors and permitted endorsees, transferees and assigns of the Secured Party. Debtor shall not assign this Agreement or any rights or obligations hereunder, and any such assignment shall be absolutely void. 

 13.3    Section Headings. Section headings are for convenience only.

 13.4    Interpretation. No uncertainty or ambiguity herein shall be construed or resolved against the Secured
Party or Debtor, whether under any rule of construction or otherwise. This Agreement shall be construed and interpreted according to the ordinary meaning of the words used so as to fairly accomplish the purposes and intentions of the parties. 

13.5    Severability of Provisions. Each provision of this Agreement shall be severable from every other provision
of this Agreement for the purpose of determining the legal enforceability of any specific provision. 

13.6    Entire Agreement; Amendments. This Agreement and the documents referenced herein contain the entire
understanding of the parties with respect to the subject matter covered herein and supersede all prior agreements, negotiations and understandings, written or oral, with respect to such subject matter. No provision of this Agreement shall be waived
or amended other than by an instrument in writing signed by Debtor and the Secured Party. 
 13.7    Good Faith.
The parties intend and agree that their respective rights, duties, powers, liabilities and obligations shall be performed, carried out, discharged and exercised reasonably and in good faith. 

13.8    Waiver and Consent. No delay or omission on the part of the Secured Party in exercising any right shall
operate as a waiver of such right or any other right. A waiver by the Secured Party of a provision of this Agreement shall not prejudice or constitute a waiver of the Secured Party’s right otherwise to demand strict compliance with that
provision or any other provision of this Agreement. No prior waiver by the Secured Party, nor any course of dealing between the Secured Party and Debtor, shall constitute a subsequent waiver of any of the Secured Party’s rights or of any of
Debtor’s obligations. Whenever the consent of the Secured Party is required under this Agreement, the granting of such consent by the Secured Party in any instance shall not constitute continuing consent to subsequent instances where such
consent is required and in all cases such consent may be granted or withheld in the sole discretion of the Secured Party. 

13.9    Counterparts. This Agreement may be executed in any number of counterparts, each of which, when executed
and delivered, shall be deemed to be an original, and all of which, when taken together, shall constitute but one and the same agreement. 

13.10    Termination. Upon full satisfaction or other termination of the Obligations (i) the Secured Party
shall release and return to Debtor all of the Collateral and any and all certificates and other documentation representing or relating to the Collateral and (ii) the security interests provided for under this Agreement shall be terminated and
of no further force and effect. At Debtor’s expense, the Secured Party shall take all actions reasonably requested by Debtor in connection with the foregoing. 

13.11    Attorney’s Fees. If a party to this Agreement shall bring any action for relief against
the other party arising out of or in connection with this Agreement, in addition to all other remedies to which the prevailing party may be entitled, the losing party shall be 

 
required to pay to the prevailing party a reasonable sum for attorney’s fees and costs incurred in bringing or defending such action and/or enforcing any judgment granted therein, all of
which shall be deemed to have accrued upon the commencement of such action and shall be paid whether or not such action is prosecuted to judgment. Any judgment or order entered in such action shall contain a specific provision providing for the
recovery of attorney’s fees and costs incurred in enforcing such judgment. For the purposes of this Section, attorney’s fees shall include, without limitation, fees incurred with respect to the following: (i) post-judgment motions,
(ii) contempt proceedings, (iii) garnishment, levy and debtor and third party examinations, (iv) discovery, (v) bankruptcy litigation and (vi) any appellate proceedings.
