Washington Street, Newton, Massachusetts 02462 (“Bank”), and LTX CORPORATION a Massachusetts corporation (“Borrower”), provides the terms on which Bank shall extend credit to Borrower and Borrower shall repay
Bank. The parties agree as follows: 
 1 ACCOUNTING AND OTHER TERMS 
 Accounting terms not defined in this Agreement shall be construed following GAAP. Calculations and determinations must be made following GAAP. The term
“financial statements” includes the notes and schedules attached thereto. The terms “including” and “includes” always mean “including (or includes) without limitation,” in this or any Loan Document.
Capitalized terms in this Agreement shall have the meanings set forth in Article 13. All other terms contained in this Agreement, unless otherwise indicated, shall have the meaning provided by the Code, to the extent such terms are defined therein.

 2 LOAN AND TERMS OF PAYMENT 
 2.1 Promise to Pay. Borrower hereby unconditionally promises to pay Bank the unpaid principal amount of all Credit Extensions and interest on the unpaid principal amount of the Credit Extensions 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, Bank shall make Advances not exceeding the Availability Amount. Amounts
borrowed under the Revolving Line may be repaid and, prior to the Revolving Line Maturity Date, reborrowed, subject to the applicable terms and conditions precedent herein. 
 (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 face amount of outstanding Letters of Credit (including drawn but unreimbursed Letters of Credit and any Letter of Credit Reserve) may not exceed Thirty Million Dollars ($30,000,000.00), inclusive of all Credit Extensions relating to Sections
2.1.1, 2.1.3, and 2.1.4. Such aggregate amounts utilized hereunder shall at all times reduce the amount otherwise available for Advances under the Revolving Line. 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 Three Million Dollars ($3,000,000.00) (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 and the aggregate amount of FX Forward Contracts may not exceed Thirty Million Dollars
($30,000,000.00), inclusive of all Credit Extensions relating to Sections 2.1.1, 2.1.2, and 2.1.4.. 
 2.1.4 Cash Management Services
Sublimit. Borrower may use up to Thirty Million Dollars ($30,000,000.00) (the “Cash Management Services Sublimit”), inclusive of all Credit Extensions relating to Sections 2.1.1, 2.1.2, and 2.1.3, 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 or any amounts that are not paid by 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. 

 (a) Availability. Bank shall
make one (1) advance (the “Term Loan Advance”), on behalf of Borrower, in an amount up to the Term Loan, on or within ten (10) days after the Effective Date.

outstanding Term Loan principal and accrued interest on the Term Loan Maturity Date.

Bank’s obligation to lend the undisbursed portion of the Credit Extensions shall terminate if there has been a material adverse change in the general affairs, management, results of operation, condition (financial or otherwise) or the prospect
of repayment of the Obligations, or there has been any material adverse deviation by Borrower from the most recent business plan of Borrower presented to and accepted by Bank prior to the execution of this Agreement.

 4 CREATION OF SECURITY INTEREST

 4.1 Grant of Security Interest. Borrower hereby grants Bank, to secure the payment and performance in full of all of the
Obligations and the performance of each of Borrower’s duties under the Loan Documents, 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. Subject to Section 5.2, Borrower warrants and represents that the security interest granted herein shall be a first priority security interest in the Collateral. 
 Except as noted on the Perfection Certificate, Borrower is not a party to, nor is bound by, any material license (other than over the counter software
that is commercially available to the public) or other material agreement with respect to which Borrower is the licensee that prohibits or otherwise restricts Borrower from granting a security interest in Borrower’s interest in such license or
agreement or any other property. Borrower shall provide written notice to Bank within ten (10) days of entering or becoming bound by, any such license or agreement which is reasonably likely to have a material impact on Borrower’s business
or financial condition. Borrower shall take such steps as Bank reasonably requests to obtain the consent of, authorization by or waiver by, any person whose consent or waiver is necessary for all such licenses or contract rights to be deemed
“Collateral” and for Bank to have a security interest in it that might otherwise be restricted or prohibited by law or by the terms of any such license or agreement, whether now existing or entered into in the future. 
 If Borrower shall, at any time, acquire a commercial tort claim in excess of One Million Dollars ($1,000,000.00), Borrower shall promptly notify Bank in
a writing signed by Borrower of the brief 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 satisfactory to
Bank. 
 4.2 Termination by Borrower. 
 Borrower may terminate this Agreement by sending written notice to Bank and paying in full all Obligations. If this Agreement is terminated, Bank’s lien and security interest in the Collateral shall continue
until Borrower fully satisfies the Obligations. 
 4.3 Authorization to File Financing Statements. Borrower hereby authorizes
Bank to file UCC financing statements, without notice to Borrower, with all appropriate jurisdictions in order 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. 
 5 REPRESENTATIONS AND WARRANTIES

  

 -4- 

 Borrower represents and warrants to Bank as follows: 
 5.1 Due Organization and Authorization. Borrower, and each Subsidiary, is duly existing and in good standing in its state of formation and
qualified and licensed to do business in, and in good standing in, any state 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 delivered to Bank a perfection certificate signed by Borrower (the “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; and (b) Borrower is an organization of the type, and is organized in the jurisdiction, set forth in the Perfection
Certificate; and (c) the Perfection Certificate accurately sets forth Borrower’s organizational identification number or accurately states that Borrower has none; and (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, and (e) all other information set forth on the Perfection Certificate pertaining to Borrower is
accurate and complete. If Borrower does not now have an organizational identification number, but later obtains one, Borrower shall forthwith notify Bank of such organizational identification number. 
 The execution, delivery and performance of the Loan Documents have been duly authorized, and do not conflict with Borrower’s organizational
documents, nor shall they constitute an event of default under any material agreement by which Borrower is bound. Borrower is not in default under any agreement to which or by which it is bound in which the default could reasonably be expected to
have a material adverse effect on Borrower’s business. 
 5.2 Collateral. Borrower has good title to the Collateral, free
of Liens except Permitted Liens. Borrower has no deposit account, other than the deposit accounts with Bank and deposit accounts described in the Perfection Certificate. The Collateral is not in the possession of any third party bailee (such as a
warehouse); provided, however, Borrower may keep up to Twenty-Five Million Dollars ($25,000,000.00) of Inventory with a third party bailee. Except as hereafter disclosed to Bank in writing by Borrower, none of the components of the Collateral shall
be maintained at locations other than as provided in the Perfection Certificate. 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 acknowledge in writing that the bailee is holding such Collateral for the benefit of Bank. 
 5.3 Litigation. Except as shown in the Perfection Certificate, there are no actions or proceedings pending or, to the knowledge of Borrower’s Responsible Officers, threatened by or against Borrower or any Subsidiary in
which an adverse decision could reasonably be expected to cause a Material Adverse Change. 
 5.4 No Material Deterioration in
Financial Statements. All consolidated financial statements for Borrower and any Subsidiary 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. 
 5.5 Solvency. The fair salable value of Borrower’s assets (including goodwill minus disposition costs) exceeds the fair value of its
liabilities; and Borrower is able to pay its debts (including trade debts) as they mature. 
 5.6 Regulatory Compliance.
Borrower is not an “investment company” or a company “controlled” by an “investment company” under the Investment Company Act of 1940. 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. Borrower has not violated any laws, ordinances or rules, the violation
of which could reasonably be expected to have a material adverse effect on Borrower’s business. None of Borrower’s or any Subsidiary’s 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 Subsidiary has timely filed all required tax returns and paid, or made adequate provision to
pay, all material taxes, except those being contested in good faith with adequate reserves under GAAP. Borrower and each Subsidiary has obtained all consents, approvals and authorizations of, made all declarations or filings with, and 

  

 -5- 

 
given all notices to, all government authorities that are necessary to continue its business as currently conducted except where the failure to obtain or
make such consents, declarations, notices or filings would not reasonably be expected to cause a Material Adverse Change. 
 5.7
Subsidiaries; Investments. Borrower does not own any stock, partnership interest or other equity securities except for Permitted Investments. 
 5.8 Full Disclosure. No written representation, warranty or other statement of Borrower in any certificate or written statement given to Bank 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. Borrower shall maintain
its, and all 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 or operations or would reasonably be expected to cause a Material Adverse Change.

and take any action under the policies Bank deems prudent.

any institution other than Bank. In addition, for each such account that Borrower at any time opens or maintains, Borrower shall, at Bank’s request and option, pursuant to an agreement in form and substance acceptable to Bank, cause the

within the ten (10) day period or cannot after diligent attempts by Borrower be cured within such ten (10) day period, and such default is likely to be cured within a reasonable time, then Borrower shall have an additional period (which

right by such third party or parties, to accelerate the maturity of any Indebtedness in an amount in excess of Five Hundred Thousand Dollars ($500,000.00) and such Indebtedness is in fact accelerated, or that could result in a Material Adverse
Change.

 9 BANK’S RIGHTS AND REMEDIES 
 9.1 Rights and Remedies. When an Event of Default occurs and continues, Bank may, without notice or demand, do any or all of the following:

 (a) Provided that either (i) an Event of Default (other than an Event of Default described in Section 8.3) occurs and continues,
or (ii) a MAC Event occurs and continues, 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) deposits 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 and notify
any Person owing Borrower money of Bank’s security interest in such funds and verify and/or collect the amounts owed by such account debtors. After the occurrence of an Event of Default, any amounts received by Borrower shall be held in trust
by Borrower for Bank, and, if requested by Bank, Borrower shall immediately deliver such receipts to Bank in the form received from the account debtor, with proper endorsements for deposit; 
 (f) Make any payments and do any acts it considers necessary or reasonable to protect 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; and 
 (j) Exercise all rights and remedies and dispose of the Collateral according to the Code. 
 9.2 Power of Attorney. Borrower hereby irrevocably appoints Bank as its lawful attorney-in-fact, to be effective 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 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 

  

 -10- 

 
claims under Borrower’s insurance policies; and (e) 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 any security interest 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 Bank Expenses. Any amounts paid by Bank as provided herein shall constitute Bank Expenses and are immediately due and payable, and shall bear interest at the then applicable rate hereunder and be secured by the Collateral.
No payments by Bank shall be deemed an agreement to make similar payments in the future or Bank’s waiver of any Event of Default. 
 9.4 Bank’s Liability for Collateral. So long as Bank complies with reasonable banking practices regarding the safekeeping of Collateral and Section 9-207 of the Code, 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. 
 9.5 Remedies Cumulative. Bank’s rights and remedies under
this Agreement, the Loan Documents, and all other agreements 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 is not a waiver, election, or acquiescence. No waiver hereunder shall be effective unless signed by Bank and then is only effective for the specific instance and purpose for which it
was given. 
 9.6 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. 
 10 NOTICES

demands by any party to this Agreement or any related agreement must be in writing and be personally delivered or sent by an overnight delivery service, by certified mail, postage prepaid, return receipt requested, or by facsimile at the addresses

 11 CHOICE OF LAW, VENUE AND JURY TRIAL WAIVER 
 Massachusetts 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 Massachusetts; provided, however, that if for any reason Bank cannot avail itself of such courts in the Commonwealth of Massachusetts, Borrower accepts jurisdiction of the courts and venue in Santa Clara County,
California. NOTWITHSTANDING THE FOREGOING, BANK SHALL HAVE THE RIGHT TO BRING ANY ACTION OR PROCEEDING AGAINST BORROWER OR ITS PROPERTY IN THE COURTS OF ANY OTHER JURISDICTION WHICH BANK DEEMS NECESSARY OR APPROPRIATE IN ORDER TO REALIZE ON THE
COLLATERAL OR TO OTHERWISE ENFORCE BANK’S RIGHTS AGAINST BORROWER OR ITS PROPERTY. 
 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. 
 12 GENERAL PROVISIONS 
 12.1 Successors and Assigns. This Agreement binds and is for the benefit of the successors and permitted assigns of each party. Borrower may
not assign this Agreement or any rights or Obligations under it without Bank’s prior written consent which may be granted or withheld in Bank’s discretion. Bank has the right, without the consent of or notice to Borrower, to sell,
transfer, assign, negotiate, or grant participation in all or any part of, or any interest in, Bank’s obligations, rights and benefits under this Agreement, the Loan Documents or any related agreement. 
 12.2 Indemnification. Borrower hereby indemnifies, defends and holds Bank and its directors, officers, employees and agents harmless
against: (a) all obligations, demands, claims, and liabilities asserted by any other party or Person in connection with the transactions contemplated by the Loan Documents; and (b) all losses or Bank Expenses incurred, or paid by Bank
from, following, or consequential to transactions between Bank and

Borrower (including reasonable attorneys’ fees and expenses), except for losses caused by Bank’s gross negligence or willful misconduct.

 12.3 Right of Set Off. Borrower hereby grants to Bank, a lien, security interest and right of set off as security for all
Obligations to Bank, whether now existing or hereafter arising upon and against all deposits, credits, collateral and property, now or hereafter in the possession, custody, safekeeping or control of Bank or any entity under the control of Bank
(including a Bank subsidiary) or in transit to any of them. At any time after the occurrence and during the continuance of an Event of Default, without demand or notice, Bank may set off the same or any part thereof and apply the same to any
liability or obligation of Borrower even though unmatured and regardless of the adequacy of any other collateral securing the Obligations. ANY AND ALL RIGHTS TO REQUIRE BANK TO EXERCISE ITS RIGHTS OR REMEDIES WITH RESPECT TO ANY OTHER COLLATERAL
WHICH SECURES THE OBLIGATIONS, PRIOR TO EXERCISING ITS RIGHT OF SETOFF WITH RESPECT TO SUCH DEPOSITS, CREDITS OR OTHER PROPERTY OF BORROWER ARE HEREBY KNOWINGLY, VOLUNTARILY AND IRREVOCABLY WAIVED. 
 12.4 Time of Essence. Time is of the essence for the performance of all Obligations in this Agreement.

of any provision.

both Bank and Borrower. This Agreement and the Loan Documents represent the entire agreement about this subject matter, and supersede prior negotiations or agreements. All prior agreements, understandings, representations, warranties, and
negotiations between the parties about the subject matter of this Agreement and the Loan Documents merge into this Agreement and the Loan Documents. 
 12.7 Counterparts. This Agreement may be executed in any number of counterparts and by different parties on separate counterparts, each of which, when executed and delivered, are an original, and all
taken together, constitute one Agreement. 
 12.8 Survival. All covenants, representations and warranties made in this
Agreement continue in full force until this Agreement has terminated pursuant to its terms, and all Obligations have been satisfied.. The obligation of Borrower in Section 12.2 to indemnify Bank shall survive until the statute of limitations
with respect to such claim or cause of action shall have run. 
 12.9 Confidentiality. In handling any confidential
information, Bank shall exercise the same degree of care that it exercises for its own proprietary information, but disclosure of information may be made: (a) to Bank’s subsidiaries or affiliates in connection with their business with
Borrower; (b) to prospective transferees or purchasers of any interest in the Credit Extensions (provided, however, Bank shall use commercially reasonable efforts in obtaining such prospective transferee’s or purchaser’s agreement to
the terms of this provision); (c) as required by law, regulation, subpoena, or other order, (d) as required in connection with Bank’s examination or audit; and (e) as Bank considers appropriate in exercising remedies under this
Agreement. Confidential information does not include information that either: (i) is in the public domain or in Bank’s possession when disclosed to Bank, or becomes part of the public domain after disclosure to Bank; or (ii) is
