	[  ]	 Translator’s NoteAmended and Restated Loan and Security Agreement

 Exhibit 10.24 
 GCT SEMICONDUCTOR, INC. 
 AMENDED AND RESTATED LOAN AND SECURITY AGREEMENT

 This AMENDED AND RESTATED LOAN AND SECURITY AGREEMENT (this “Agreement”) is
entered into as of April 4, 2011, by and between Comerica Bank (“Bank”) and GCT Semiconductor, Inc. (“Borrower”). 
 RECITALS 
 Borrower and Bank are parties to that certain Loan and
Security Agreement dated as of August 20, 2003, as amended from time to time (the “Original Agreement”). 

Borrower and Bank wish to amend and restate the terms of the Original Agreement. This Agreement sets forth the terms on which Bank will
advance credit to Borrower, and Borrower will repay the amounts owing to Bank. 
 AGREEMENT 

The parties agree as follows: 

1. DEFINITIONS AND CONSTRUCTION. 
 1.1 Definitions. As used in this Agreement, all capitalized terms shall have the definitions set forth on Exhibit A. Any term used in the Code and not defined herein shall have the meaning
given to the term in the Code. 
 1.2 Accounting Terms. Any accounting term not specifically defined on
Exhibit A shall be construed in accordance with GAAP and all calculations shall be made in accordance with GAAP. The term “financial statements” shall include the accompanying notes and schedules. 

2. LOAN AND TERMS OF PAYMENT. 
 2.1 Credit Extensions. 
 (a) Promise to
Pay. Borrower promises to pay to Bank, in lawful money of the United States of America, the aggregate unpaid principal amount of all Credit Extensions made by Bank to Borrower, together with interest on the unpaid principal amount of such Credit
Extensions at the rates specified in this Agreement or the Interest Rate Addendum (defined below), in each case in accordance with the terms hereof. 

(b) Advances under Revolving Line. 

(i) Amount. Subject to and upon the terms and conditions of this Agreement Borrower may request
Advances in an aggregate outstanding amount not to exceed the lesser of (A) the Revolving Line or (B) the Borrowing Base, less the aggregate face amount of Letters of Credit issued under the Letter of Credit Sublimit and the aggregate
limits of the corporate credit cards issued to Borrower and merchant credit card processing reserves under the Credit Card Services Sublimit. Amounts borrowed pursuant to this Section 2.1(b) may be repaid and reborrowed at any time without
penalty or premium prior to the Revolving Maturity Date, at which time all Advances under this Section 2.1(b) shall be immediately due and payable. 

(ii) Form of Request. Whenever Borrower desires an Advance, Borrower will notify Bank by facsimile
transmission or telephone no later than 3:00 p.m. Pacific time (1:30 p.m. Pacific time for wire transfers), on the Business Day that the Advance is to be made. Each such notification shall be promptly confirmed by a Payment/Advance Form in
substantially the form of Exhibit C. Bank is authorized to make Advances under this Agreement, based upon instructions received from a Responsible Officer or a designee of a Responsible Officer, or without instructions if in Bank’s
discretion such Advances are necessary to meet Obligations which have become due and remain unpaid. Bank shall be entitled to rely on any facsimile or telephonic notice given by a person who Bank reasonably believes to be a Responsible Officer or a
designee thereof, and Borrower shall indemnify and hold Bank harmless for any damages or loss suffered by Bank as a result of such reliance. Bank will credit the amount of Advances made under this Section 2.1(b) to Borrower’s deposit
account, unless otherwise specified in the applicable Payment/Advance Form. 

 (iii) Letter of Credit Sublimit. Subject to the
availability under the Revolving Line, and in reliance on the representations and warranties of Borrower set forth herein, at any time and from time to time from the date hereof through the Business Day immediately prior to the Revolving Maturity
Date, Bank shall issue for the account of Borrower such Letters of Credit as Borrower may request by delivering to Bank a duly executed letter of credit application on Bank’s standard form; provided, however, that the outstanding and undrawn
amounts under all such Letters of Credit (i) shall not at any time exceed the Letter of Credit Sublimit, and (ii) shall be deemed to constitute Advances for the purpose of calculating availability under the Revolving Line. Any drawn but
unreimbursed amounts under any Letters of Credit shall be charged as Advances against the Revolving Line. 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 form application and letter of credit agreement. Borrower will pay any standard issuance and other fees that Bank notifies Borrower it will charge for issuing and processing Letters of Credit. 

(iv) Credit Card Services Sublimit. Subject to the terms and conditions of this Agreement, Borrower
may request corporate credit cards and standard and e-commerce merchant account services from Bank (collectively, the “Credit Card Services”). The aggregate limit of the corporate credit cards and merchant credit card processing reserves
shall not exceed the Credit Card Services Sublimit, provided that availability under the Revolving Line shall be reduced by the aggregate limits of the corporate credit cards issued to Borrower and merchant credit card processing reserves. In
addition, Bank may, in its sole discretion, charge as Advances any amounts that become due or owing to Bank in connection with the Credit Card Services. The terms and conditions (including repayment and fees) of such Credit Card Services shall be
subject to the terms and conditions of the Bank’s standard forms of application and agreement for the Credit Card Services, which Borrower hereby agrees to execute. 

(v) Collateralization of Obligations Extending Beyond Maturity. If any Letters of Credit or Credit
Card Services extend beyond the Revolving Maturity Date, then, effective as of the Revolving Maturity Date, the balance in any deposit accounts held by Bank and the certificates of deposit or time deposit accounts issued by Bank in Borrower’s
name (and any interest paid thereon or proceeds thereof, including any amounts payable upon the maturity or liquidation of such certificates or accounts), shall automatically secure such obligations to the extent of the then continuing or
outstanding and undrawn Letters of Credit, Credit Card Services; provided, however, that if there are insufficient balances in such accounts to secure such obligations, Borrower shall promptly (but in any event within two Business Days) deposit such
additional funds as are necessary to fully secure such obligations. Borrower authorizes Bank to hold such balances in pledge and to decline to honor any drafts thereon or any requests by Borrower or any other Person to pay or otherwise transfer any
part of such balances for so long as the Letters of Credit or Credit Card Services are outstanding or continue. 

2.2 Overadvances. If the aggregate amount of the outstanding Advances exceeds the lesser of the Revolving Line
plus the aggregate face amount of Letters of Credit issued under the Letter of Credit Sublimit and the aggregate limits of the corporate credit cards issued to Borrower and merchant credit card processing reserves under the Credit Card
Services Sublimit or the Borrowing Base at any time minus the aggregate face amount of Letters of Credit issued under the Letter of Credit Sublimit and the aggregate limits of the corporate credit cards issued to Borrower and merchant credit card
processing reserves under the Credit Card Services Sublimit, Borrower shall immediately pay to Bank, in cash, the amount of such excess. 
 2.3 Interest Rates, Payments, and Calculations. 
 (a) Interest Rates. Except as set forth in Section 2.3(b), the Advances shall bear interest, on the outstanding daily balance thereof, as set forth in the Prime Referenced Rate Addendum to
Amended and Restated Loan and Security Agreement attached hereto as Exhibit F (the “Interest Rate Addendum”). 
 (b) Late Fee; Default Rate. If any payment is not made within 10 days after the date such payment is due, Borrower shall pay Bank a late fee equal to the lesser of (i) five percent
(5%) of the amount of such unpaid amount or (ii) the maximum amount permitted to be charged under applicable law. All Obligations shall bear interest, from and after the occurrence and during the continuance of an Event of Default, at a
rate equal to five (5) percentage points above the interest rate otherwise applicable immediately prior to the occurrence of the Event of Default. 

  
 2 

 (c) Payments. Except as set forth in the Interest
Rate Addendum, interest hereunder shall be due and payable in arrears on the first (1st) calendar day of each month during the term hereof. Bank shall, at its option, charge such interest, all Bank Expenses, and all Periodic Payments against
any of Borrower’s deposit accounts or against the Revolving Line, in which case those amounts shall thereafter accrue interest at the rate then applicable hereunder. Any interest not paid when due shall be compounded by becoming a part of the
Obligations, and such interest shall thereafter accrue interest at the rate then applicable hereunder. 
 (d) Computation. In the event the Prime Rate is changed from time to time hereafter, the applicable rate of interest hereunder shall be increased or decreased, effective as of the day the Prime
Rate is changed, by an amount equal to such change in the Prime Rate. All interest chargeable under the Loan Documents shall be computed on the basis of a three hundred sixty (360) day year for the actual number of days elapsed. 

2.4 Crediting Payments. Prior to the occurrence of an Event of Default, Bank shall credit a wire transfer of
funds, check or other item of payment to such deposit account or Obligation as Borrower specifies. After the occurrence of an Event of Default, Bank shall have the right, in its sole discretion, to immediately apply any wire transfer of funds,
check, or other item of payment Bank may receive to conditionally reduce Obligations, but such applications of funds shall not be considered a payment on account unless such payment is of immediately available federal funds or unless and until such
check or other item of payment is honored when presented for payment. Notwithstanding anything to the contrary contained herein, any wire transfer or payment received by Bank after 12:00 noon Pacific time shall be deemed to have been received by
Bank as of the opening of business on the immediately following Business Day. Whenever any payment to Bank under the Loan Documents would otherwise be due (except by reason of acceleration) on a date that is not a Business Day, such payment shall
instead be due on the next Business Day, and additional fees or interest, as the case may be, shall accrue and be payable for the period of such extension. 
 2.5 Fees. Borrower shall pay to Bank the following: 
 (a) Renewal Fee. A nonrefundable fee equal to $15,000, paid annually, commencing July 4, 2011 and on the same day of each July thereafter until the Revolving Line is terminated; and

 (b) Bank Expenses. On the Closing Date, all Bank Expenses incurred through the Closing
Date, and, after the Closing Date, all Bank Expenses as and when they become due. 
 2.6 Term. This
Agreement shall become effective on the Closing Date and, subject to Section 13.8, shall continue in full force and effect for so long as any Obligations remain outstanding or Bank has any obligation to make Credit Extensions under this
Agreement. Notwithstanding the foregoing, Bank shall have the right to terminate its obligation to make Credit Extensions under this Agreement immediately and without notice upon the occurrence and during the continuance of an Event of Default.
Borrower may terminate this Agreement at any time upon five (5) days prior written notice to Bank provided that all outstanding Obligations have been paid in full as of the effective date of such termination. 

3. CONDITIONS OF LOANS. 
 3.1 Conditions Precedent to Initial Credit Extension. The obligation of Bank to make the initial Credit Extension is subject to the condition precedent that Bank shall have received, in form and
substance satisfactory to Bank, the following: 
 (a) this Agreement; 

(b) an officer’s certificate of Borrower with respect to incumbency and resolutions authorizing the
execution and delivery of this Agreement; 
 (c) a financing statement (Form UCC-1); 

(d) agreement to furnish insurance; 

  
 3 

 (e) payment of the fees and Bank Expenses then due specified
in Section 2.5; 
 (f) current SOS Reports indicating that except for Permitted Liens, there
are no other security interests or Liens of record in the Collateral; 
 (g) current financial
statements, including company prepared consolidated and consolidating balance sheets and income statements for the most recently ended month in accordance with Section 6.2, and such other updated financial information as Bank may reasonably
request; 
 (h) current Compliance Certificate in accordance with Section 6.2; 

(i) an Automatic Debit Authorization; 

(j) a subordination agreement duly executed by United Microelectronics Corporation; and 

(k) such other documents or certificates, and completion of such other matters, as Bank may reasonably
deem necessary or appropriate. 
 3.2 Conditions Precedent to all Credit Extensions. The obligation of
Bank to make each Credit Extension, including the initial Credit Extension, is further subject to the following conditions: 
 (a) timely receipt by Bank of the Payment/Advance Form as provided in Section 2.1; and 
 (b) the representations and warranties contained in Article 5 shall be true and correct in all material respects on and as of the date of such Payment/Advance Form and on the effective date of each Credit
Extension as though made at and as of each such date, and no Event of Default shall have occurred and be continuing, or would exist after giving effect to such Credit Extension (provided, however, that those representations and warranties expressly
referring to another date shall be true, correct and complete in all material respects as of such date). The making of each Credit Extension shall be deemed to be a representation and warranty by Borrower on the date of such Credit Extension as to
the accuracy of the facts referred to in this Section 3.2. 
 4. CREATION OF SECURITY INTEREST. 

4.1 Grant of Security Interest. Borrower grants and pledges to Bank a continuing security interest in the
Collateral to secure prompt repayment of any and all Obligations and to secure prompt performance by Borrower of each of its covenants and duties under the Loan Documents. Except as set forth in the Schedule, such security interest constitutes a
valid, first priority security interest in the presently existing Collateral, and will constitute a valid, first priority security interest in later-acquired Collateral. Borrower also hereby agrees not to sell, transfer, assign, mortgage, pledge,
lease, grant a security interest in, or encumber any of its Intellectual Property, except in connection with Permitted Liens and Permitted Transfers. Notwithstanding any termination of this Agreement, Bank’s Lien on the Collateral shall remain
in effect for so long as any Obligations are outstanding. 
 4.2 Perfection of Security Interest.
Borrower authorizes Bank to file at any time financing statements, continuation statements, and amendments thereto that (i) either specifically describe the Collateral or describe the Collateral as all assets of Borrower of the kind pledged
hereunder, and (ii) contain any other information required by the Code for the sufficiency of filing office acceptance of any financing statement, continuation statement, or amendment, including whether Borrower is an organization, the type of
organization and any organizational identification number issued to Borrower, if applicable. Any such financing statements may be filed by Bank at any time in any jurisdiction whether or not Revised Article 9 of the Code is then in effect in that
jurisdiction. Borrower shall from time to time endorse and deliver to Bank, at the request of Bank, all Negotiable Collateral and other documents that Bank may reasonably request, in form satisfactory to Bank, to perfect and continue perfection of
Bank’s security interests in the Collateral and in order to fully consummate all of the transactions contemplated under the Loan Documents. Borrower shall have possession of the Collateral, except where expressly otherwise provided in this
Agreement or where Bank chooses to perfect its security interest by possession in addition to the filing of a financing statement. Where Collateral is in possession of a third party bailee, Borrower shall take such

  
 4 

 
steps as Bank reasonably requests for Bank to (i) obtain an acknowledgment, in form and substance satisfactory to Bank, of the bailee that the bailee holds such Collateral for the benefit of
Bank, and (ii) obtain “control” of any Collateral consisting of investment property, deposit accounts, letter-of-credit rights or electronic chattel paper (as such items and the term “control” are defined in Revised Article
9 of the Code) by causing the securities intermediary or depositary institution or issuing bank to execute a control agreement in form and substance satisfactory to Bank. Borrower will not create any chattel paper without placing a legend on the
chattel paper acceptable to Bank indicating that Bank has a security interest in the chattel paper. Borrower from time to time may deposit with Bank specific cash collateral to secure specific Obligations; Borrower authorizes Bank to hold such
specific balances in pledge and to decline to honor any drafts thereon or any request by Borrower or any other Person to pay or otherwise transfer any part of such balances for so long as the specific Obligations are outstanding. 

4.3 Right to Inspect. Bank (through any of its officers, employees, or agents) shall have the right, upon
reasonable prior notice, from time to time during Borrower’s usual business hours but no more than twice a year (unless an Event of Default has occurred and is continuing), to inspect Borrower’s Books and to make copies thereof and to
check, test, and appraise the Collateral in order to verify Borrower’s financial condition or the amount, condition of, or any other matter relating to, the Collateral. 
 5. REPRESENTATIONS AND WARRANTIES. 
 Borrower represents
and warrants as follows: 
 5.1 Due Organization and Qualification. Borrower and each Subsidiary is an
entity duly existing under the laws of the jurisdiction in which it is organized and qualified and licensed to do business in any state in which the conduct of its business or its ownership of property requires that it be so qualified, except where
the failure to do so could not reasonably be expected to cause a Material Adverse Effect. 
 5.2 Due
Authorization; No Conflict. The execution, delivery, and performance of the Loan Documents are within Borrower’s powers, have been duly authorized, and are not in conflict with nor constitute a breach of any provision contained in
Borrower’s organizational documents, nor will they constitute an event of default under any material agreement by which Borrower is bound. Borrower is not in default under any agreement by which it is bound, except to the extent such default
would not reasonably be expected to cause a Material Adverse Effect. 
 5.3 Collateral. Borrower has
rights in or the power to transfer the Collateral, and its title to the Collateral is free and clear of Liens, adverse claims, and restrictions on transfer or pledge except for Permitted Liens. Except for works in progress or finished goods located

delivered or rendered to the account debtor or its agent for immediate shipment to and unconditional acceptance by the account debtor. Borrower has not received notice of actual or imminent Insolvency Proceeding of any account debtor whose accounts
are included in any Borrowing Base Certificate as an Eligible Account. No licenses or agreements giving rise to such Eligible Accounts is with any Prohibited Territory or with any Person organized under or doing business in a Prohibited Territory.
All Inventory is in all material respects of good and merchantable quality, free from all material defects, except for Inventory for which adequate reserves have been made. Except as set forth in the Schedule, none of the Collateral is maintained or
invested with a Person other than Bank or Bank’s Affiliates. 
 5.4 Intellectual Property. Borrower
is the sole owner of the Intellectual Property, except for licenses granted by Borrower to its customers in the ordinary course of business. To the best of Borrower’s knowledge, each of the Copyrights, Trademarks and Patents is valid and
enforceable, and no part of the Intellectual Property has been judged invalid or unenforceable, in whole or in part, and no claim has been made to Borrower that any part of the Intellectual Property violates the rights of any third party except to
the extent such claim could not reasonably be expected to cause a Material Adverse Effect. 
 5.5 Name;
Location of Chief Executive Office. Except as disclosed in the Schedule, Borrower has not done business under any name other than that specified on the signature page hereof, and its exact legal name is as

  
 5 

 
set forth in the first paragraph of this Agreement. The chief executive office of Borrower is located in the Chief Executive Office State at the address indicated in Section 10 hereof.

 5.6 Actions, Suits, Litigation, or Proceedings. Except as set forth in the Schedule, there are no
actions, suits, litigation or proceedings, at law or in equity, pending by or against Borrower or any Subsidiary before any court, administrative agency, or arbitrator in which a likely adverse decision could reasonably be expected to have a
Material Adverse Effect. 
 5.7 No Material Adverse Change in Financial Statements. All consolidated and
consolidating financial statements related to Borrower and any Subsidiary that are delivered by Borrower to Bank fairly present in all material respects Borrower’s consolidated and consolidating financial condition as of the date thereof and
Borrower’s consolidated and consolidating results of operations for the period then ended. There has not been a material adverse change in the consolidated or in the consolidating financial condition of Borrower since the date of the most
recent of such financial statements submitted to Bank. 
 5.8 Solvency, Payment of Debts. Borrower is
able to pay its debts (including trade debts) as they mature; the fair saleable value of Borrower’s assets (including goodwill minus disposition costs) exceeds the fair value of its liabilities; and Borrower is not left with unreasonably small

 5.9 Compliance with Laws and
Regulations. Borrower and each Subsidiary have met the minimum funding requirements of ERISA with respect to any employee benefit plans subject to ERISA. No event has occurred resulting from Borrower’s failure to comply with ERISA that is
reasonably likely to result in Borrower’s incurring any liability that could reasonably be expected to have a Material Adverse Effect. Borrower is not an “investment company” or a company “controlled” by an “investment
company” within the meaning of the Investment Company Act of 1940. Borrower is not engaged principally, or as one of the important activities, in the business of extending credit for the purpose of purchasing or carrying margin stock (within
the meaning of Regulations T and U of the Board of Governors of the Federal Reserve System). Borrower has complied in all material respects with all the provisions of the Federal Fair Labor Standards Act. Borrower is in compliance with all
environmental laws, regulations and ordinances except where the failure to comply is not reasonably likely to have a Material Adverse Effect. Borrower has not violated any statutes, laws, ordinances or rules applicable to it, the violation of which

 5.11 Government Consents.
Borrower and each Subsidiary have obtained all consents, approvals and authorizations of, made all declarations or filings with, and given all notices to, all governmental authorities that are necessary for the continued operation of Borrower’s
business as currently conducted, except where the failure to do so would not reasonably be expected to cause a Material Adverse Effect. 
 5.12 Inbound Licenses. Except as disclosed on the Schedule, Borrower is not a party to, nor is bound by, any material inbound license or other agreement, the failure, breach, or termination of
which could reasonably be expected to cause a Material Adverse Effect, or that prohibits or otherwise restricts Borrower from granting a security interest in Borrower’s interest in such license or agreement or any other property. 

5.13 Full Disclosure. No representation, warranty or other statement made by Borrower in any certificate or written
statement furnished to Bank taken together with all such certificates and written statements furnished to Bank contains any untrue statement of a material fact or omits to state a material fact necessary in order to make the statements contained in
such 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 to

  
 6 

 
be viewed as facts and that actual results during the period or periods covered by any such projections and forecasts may differ from the projected or forecasted results. 

6. AFFIRMATIVE COVENANTS. 
 Borrower covenants that, until payment in full of all outstanding Obligations, and for so long as Bank may have any commitment to make a Credit Extension hereunder, Borrower shall do all of the following:

 6.1 Good Standing and Government Compliance. Borrower shall maintain its and each of its
Subsidiaries’ organizational existence and good standing in the Borrower State, shall maintain qualification and good standing in each other jurisdiction in which the failure to so qualify could reasonably be expected to have a Material Adverse

minimum funding requirements of ERISA with respect to any employee benefit plans subject to ERISA, if applicable. Borrower shall comply in all material respects with all applicable Environmental Laws, and maintain all material permits, licenses and
approvals required thereunder where the failure to do so could reasonably be expected to have a Material Adverse Effect. Borrower shall comply, and shall cause each Subsidiary to comply, with all statutes, laws, ordinances and government rules and
regulations to which it is subject, and shall maintain, and shall cause each of its Subsidiaries to maintain, in force all licenses, approvals and agreements, the loss of which or failure to comply with which would reasonably be expected to have a
Material Adverse Effect. 
 6.2 Financial Statements, Reports, Certificates. Borrower shall deliver to
Bank: (i) as soon as available, but in any event within thirty (30) days after the end of each calendar month, a company prepared consolidated and consolidating balance sheet and income statement covering Borrower’s operations during

Borrower may deliver to Bank on an electronic basis any certificates, reports or information required pursuant to this
Section 6.2, and Bank shall be entitled to rely on the information contained in the electronic files, provided that Bank in good faith believes that the files were delivered by a Responsible Officer. If Borrower delivers this information
electronically, it shall also deliver to Bank by U.S. Mail, reputable overnight courier service, hand delivery, facsimile or pdf file within five (5) Business Days of submission of the unsigned electronic copy the certification of monthly

6.3 Inventory; Returns. Borrower shall keep all Inventory in good and merchantable condition, free from all
material defects except for Inventory for which adequate reserves have been made. Returns and allowances, if any, as between Borrower and its account debtors shall be on the same basis and in accordance with the usual customary practices of
Borrower, as they exist on the Closing Date. Borrower shall promptly notify Bank of all returns and recoveries and of all disputes and claims involving more than One Hundred Thousand Dollars ($100,000). 

6.4 Taxes. Borrower shall make, and cause each Subsidiary to make, due and timely payment or deposit of all
material federal, state, and local taxes, assessments, or contributions required of it by law, including, but not limited to, those laws concerning income taxes, F.I.C.A., F.U.T.A. and state disability, and will execute and deliver to Bank, on
demand, proof satisfactory to Bank indicating that Borrower or a Subsidiary has made such payments or deposits and any appropriate certificates attesting to the payment or deposit thereof; provided that Borrower or a Subsidiary need not make any
payment if the amount or validity of such payment is contested in good faith by appropriate proceedings and is reserved against (to the extent required by GAAP) by Borrower. 

6.5 Insurance. 

(a) Borrower, at its expense, shall keep the Collateral insured against loss or damage by fire, theft,
explosion, sprinklers, and all other hazards and risks, and in such amounts, as ordinarily insured against by other owners in similar businesses conducted in the locations where Borrower’s business is conducted on the date hereof. Borrower
shall also maintain liability and other insurance in amounts and of a type that are customary to businesses similar to Borrower’s. 
 (b) All such policies of insurance shall be in such form, with such companies, and in such amounts as reasonably satisfactory to Bank. All policies of property insurance shall contain a lender’s loss
payable endorsement, in a form satisfactory to Bank, showing Bank as an additional loss payee, and all liability insurance policies shall show Bank as an additional insured and specify that the insurer must give at least twenty (20) days notice
to Bank before canceling its policy for any reason. Upon Bank’s request, Borrower shall deliver to Bank certified copies of the policies of insurance and evidence of all premium payments. If no Event of Default has occurred and is continuing,
proceeds payable under any casualty policy will, at Borrower’s option, be payable to Borrower to replace the property subject to the claim, provided that any such replacement property shall be deemed Collateral in which Bank has been granted a
first priority security interest. If an Event of Default has occurred and is continuing, all proceeds payable under any such policy shall, at Bank’s option, be payable to Bank to be applied on account of the Obligations.

registered) with the United States Patent and Trademark Office or the United States Copyright Office, as the case may be, those registrable intellectual property rights now owned or hereafter developed or acquired by Borrower, to the extent that
Borrower, in its reasonable business judgment, deems it appropriate to so protect such intellectual property rights. 
 (b) Borrower shall (i) protect, defend and maintain the validity and enforceability of its material Trademarks, Patents, Copyrights, and trade secrets, (ii) use commercially reasonable efforts
to detect infringements of its material Trademarks, Patents and Copyrights and promptly advise Bank in writing of material infringements detected and (iii) not allow any material Trademarks, Patents or Copyrights to be abandoned, forfeited or

 7.5 Encumbrances. Create, incur, assume or allow any Lien with respect to any of its property, or
assign or otherwise convey any right to receive income, including the sale of any Accounts, or permit any of its Subsidiaries to do so, except for Permitted Liens, or covenant to any other Person that Borrower in the future will refrain from
creating, incurring, assuming or allowing any Lien with respect to any of Borrower’s property. 
 7.6
Distributions. Pay any dividends or make any other distribution or payment on account of or in redemption, retirement or purchase of any capital stock, except that Borrower may (i) repurchase the stock of former employees pursuant to
stock repurchase agreements in an aggregate amount not to exceed $100,000 per fiscal year of Borrower as long as an Event of Default does not exist prior to such repurchase or would not exist after giving effect to such repurchase, and
(ii) repurchase the stock of former employees pursuant to stock repurchase agreements by the cancellation of indebtedness owed by such former employees to Borrower regardless of whether an Event of Default exists. 

7.7 Investments. Directly or indirectly acquire or own, or make any Investment in or to any Person, or permit any
of its Subsidiaries to do so, other than Permitted Investments, or maintain or invest any of its property with a Person other than Bank or Bank’s Affiliates or permit any Subsidiary to do so unless such Person has entered into a control
agreement with Bank, in form and substance satisfactory to Bank, or suffer or permit any Subsidiary to be a party to, or be bound by, an agreement that restricts such Subsidiary from paying dividends or otherwise distributing property to Borrower.
Further, Borrower shall not enter into any license or agreement with any Prohibited Territory or with any Person organized under or doing business in a Prohibited Territory. 

7.8 Transactions with Affiliates. Directly or indirectly enter into or permit to exist any material transaction
with any Affiliate of Borrower except for transactions that are in the ordinary course of Borrower’s business, upon fair and reasonable terms that are no less favorable to Borrower than would be obtained in an arm’s length transaction with
a non-affiliated Person. 
 7.9 Subordinated Debt. Make any payment in respect of any Subordinated Debt,
or permit any of its Subsidiaries to make any such payment, except in compliance with the terms of such Subordinated Debt and the terms of the subordination agreement relating to such Subordinated Debt, or amend any provision of any document
evidencing such Subordinated Debt, except in compliance with the terms of the subordination agreement relating to such Subordinated Debt, or amend any provision affecting Bank’s rights contained in any documentation relating to the Subordinated
Debt without Bank’s prior written consent. 
 7.10 Inventory and Equipment. Store the Inventory or
the Equipment with a bailee, warehouseman, or similar third party unless the third party has been notified of Bank’s security interest and Bank (a) has received an acknowledgment from the third party that it is holding or will hold the
Inventory or Equipment for Bank’s benefit or (b) is in possession of the warehouse receipt, where negotiable, covering such Inventory or Equipment. Except for Inventory sold in the ordinary course of business, works in progress and
finished goods located with subcontractors located outside of the United States and except for such other locations as Bank may approve in writing, Borrower shall keep the Inventory and Equipment only at Borrower’s location set forth in
Section 10 and such other locations of which Borrower gives Bank prior written notice and as to which Bank files a financing statement where needed to perfect its security interest. 

7.11 No Investment Company; Margin Regulation. Become or be controlled by an “investment company,”
within the meaning of the Investment Company Act of 1940, or become principally engaged in, or undertake as one of its important activities, the business of extending credit for the purpose of purchasing or carrying margin stock, or use the proceeds
of any Credit Extension for such purpose. 

  
 10 

 7.12 Payments of Existing Notes. Make any payments owing under
Existing Notes; provided, however, Borrower may make payments under Existing Notes in the amounts set forth on Schedule 7.12 so long as (a) no Event of Default has occurred, is continuing or would exist after giving effect to any such
payments, (b) Borrower is in compliance, on a pro forma basis, with the financial covenants set forth in Section 6.7 and (c) both before and after giving effect to any such payments, the amount of Borrower’s Cash at Bank is not

8. EVENTS OF DEFAULT. 
 Any one or more of the following events shall constitute an Event of Default by Borrower under this Agreement: 
 8.1 Payment Default. If Borrower fails to pay any of the Obligations when due; 
 8.2 Covenant Default. 
 (a) If Borrower
fails to perform any obligation under Sections 6.2, 6.4, 6.5, 6.6 or 6.7 or violates any of the covenants contained in Article 7 of this Agreement; or 

(b) If Borrower fails to perform any obligation under Sections 6.1, 6.3, 6.8, 6.9 or 6.10 of this
Agreement, and has failed to cure such default within ten (10) days after Borrower receives notice thereof or any officer of Borrower becomes aware thereof; or 

(c) If Borrower fails or neglects to perform or observe any other material term, provision, condition,
covenant contained in this Agreement, in any of the Loan Documents, or in any other present or future agreement between Borrower and Bank and as to any default under such other term, provision, condition or covenant that can be cured, has failed to
cure such default within twenty (20) days after Borrower receives notice thereof or any officer of Borrower becomes aware thereof; provided, however, that if the default cannot by its nature be cured within the twenty (20) day period or
cannot after diligent attempts by Borrower be cured within such twenty (20) day period, and such default is likely to be cured within a reasonable time, then Borrower shall have an additional reasonable period (which shall not in any case
exceed forty-five (45) days) to attempt to cure such default, so long as Borrower continues to diligently attempt to cure such default, and within such reasonable time period the failure to have cured such default shall not be deemed an Event
of Default but no Credit Extensions will be made;

circumstance or circumstances that could reasonably be expected to have a Material Adverse Effect. 
 8.4
Defective Perfection. If Bank shall receive at any time following the Closing Date an SOS Report indicating that except for Permitted Liens, Bank’s security interest in the Collateral is not prior to all other security interests or Liens
of record reflected in the report;

is attached, seized, subjected to a writ or distress warrant, or is levied upon, or comes into the possession of any trustee, receiver or person acting in a similar capacity and such attachment, seizure, writ or distress warrant or levy has not been
removed, discharged or rescinded within five (5) days, or if Borrower is enjoined, restrained, or in any way prevented by court order from continuing to conduct all or any material part of its business affairs, or if a judgment or other claim
becomes a lien or encumbrance upon any material portion of Borrower’s assets, or if a notice of lien, levy, or assessment is filed of record with respect to any of Borrower’s assets by the United States Government, or any department,
agency, or instrumentality thereof, or by any state, county, municipal, or governmental agency, and the same is not paid within five (5) days after Borrower receives notice thereof, provided that none of the foregoing shall constitute an Event
of Default where such action or event is stayed or an adequate bond has been posted pending a good faith contest by Borrower (provided that no Credit Extensions will be made during such cure period); 

  
 11 

 8.6 Insolvency. If Borrower becomes insolvent, or if an Insolvency

Proceeding);

to which Borrower is a party with a third party or parties resulting in a right by such third party or parties, whether or not exercised, to accelerate the maturity of any Indebtedness in an amount in excess of One Hundred Thousand Dollars
($100,000) or that would reasonably be expected to have a Material Adverse Effect;

Document. 
 9. BANK’S RIGHTS AND REMEDIES. 

9.1 Rights and Remedies. Upon the occurrence and during the continuance of an Event of Default, Bank may, at its
election, without notice of its election and without demand, do any one or more of the following, all of which are authorized by Borrower: 
 (a) Declare all Obligations, whether evidenced by this Agreement, by any of the other Loan Documents, or otherwise, immediately due and payable (provided that upon the occurrence of an Event of Default
described in Section 8.6 (insolvency), all Obligations shall become immediately due and payable without any action by Bank); 
 (b) Demand that Borrower (i) deposit cash with Bank in an amount equal to the amount of any Letters of Credit remaining undrawn or outstanding Credit Card Services, as collateral security for the
repayment of any future drawings under such Letters of Credit or outstanding Credit Card Services, and (ii) pay in advance all Letter of Credit fees scheduled to be paid or payable over the remaining term of the Letters of Credit or Credit Card
Services fees, and Borrower shall promptly deposit and pay such amounts; 
 (c) Cease advancing
money or extending credit to or for the benefit of Borrower under this Agreement or under any other agreement between Borrower and Bank; 
 (d) Settle or adjust disputes and claims directly with account debtors for amounts, upon terms and in whatever order that Bank reasonably considers advisable; 

(e) Make such payments and do such acts as Bank considers necessary or reasonable to protect its security
interest in the Collateral. Borrower agrees to assemble the Collateral if Bank so requires, and to make the Collateral available to Bank as Bank may designate. Borrower authorizes Bank to enter the premises where the Collateral is located, to take
and maintain possession of the Collateral, or any part of it, and to pay, purchase, contest, or compromise any encumbrance, charge, or lien which in Bank’s determination appears to be prior or superior to its security interest and to pay all
expenses incurred in connection therewith. With respect to any of Borrower’s owned premises, Borrower hereby grants Bank a license to enter into possession of such premises and 

  
 12 

 
to occupy the same, without charge, in order to exercise any of Bank’s rights or remedies provided herein, at law, in equity, or otherwise; 

(f) Set off and apply to the Obligations any and all (i) balances and deposits of Borrower held by
Bank, and (ii) indebtedness at any time owing to or for the credit or the account of Borrower held by Bank; 
 (g) Ship, reclaim, recover, store, finish, maintain, repair, prepare for sale, advertise for sale, and sell (in the manner provided for herein) the Collateral. Bank is hereby granted a license or other
right, solely pursuant to the provisions of this Section 9.1, to use, without charge, Borrower’s labels, patents, copyrights, rights of use of any name, trade secrets, trade names, trademarks, service marks, and advertising matter, or any
property of a similar nature, 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 9.1, Borrower’s
rights under all licenses and all franchise agreements shall inure to Bank’s benefit; 
 (h)
Sell the Collateral at either a public or private sale, or both, by way of one or more contracts or transactions, for cash or on terms, in such manner and at such places (including Borrower’s premises) as Bank determines is commercially
reasonable, and apply any proceeds to the Obligations in whatever manner or order Bank deems appropriate. Bank may sell the Collateral without giving any warranties as to the Collateral. Bank may specifically disclaim any warranties of title or the
like. This procedure will not be considered adversely to affect the commercial reasonableness of any sale of the Collateral. If Bank sells any of the Collateral upon credit, Borrower will be credited only with payments actually made by the
purchaser, received by Bank, and applied to the indebtedness of the purchaser. If the purchaser fails to pay for the Collateral, Bank may resell the Collateral and Borrower shall be credited with the proceeds of the sale; 

(i) Bank may credit bid and purchase at any public sale; 

(j) Apply for the appointment of a receiver, trustee, liquidator or conservator of the Collateral, without
notice and without regard to the adequacy of the security for the Obligations and without regard to the solvency of Borrower, any guarantor or any other Person liable for any of the Obligations; and 

(k) Any deficiency that exists after disposition of the Collateral as provided above will be paid
immediately by Borrower. 
 Bank may comply with any applicable state or federal law requirements in connection with a
disposition of the Collateral and compliance will not be considered adversely to affect the commercial reasonableness of any sale of the Collateral. 
 9.2 Power of Attorney. Effective only upon the occurrence and during the continuance of an Event of Default, Borrower hereby irrevocably appoints Bank (and any of Bank’s designated officers,
or employees) as Borrower’s true and lawful attorney to: (a) send requests for verification of Accounts or notify account debtors of Bank’s security interest in the Accounts; (b) endorse Borrower’s name on any checks or
other forms of payment or security that may come into Bank’s possession; (c) sign Borrower’s name on any invoice or bill of lading relating to any Account, drafts against account debtors, schedules and assignments of Accounts,
verifications of Accounts, and notices to account debtors; (d) dispose of any Collateral; (e) make, settle, and adjust all claims under and decisions with respect to Borrower’s policies of insurance; (f) settle and adjust
disputes and claims respecting the accounts directly with account debtors, for amounts and upon terms which Bank determines to be reasonable; and (g) file, in its sole discretion, one or more financing or continuation statements and amendments
thereto, relative to any of the Collateral without the signature of Borrower where permitted by law; provided Bank may exercise such power of attorney to sign the name of Borrower on any of the documents described in clause (g) above,
regardless of whether an Event of Default has occurred. The appointment of Bank as Borrower’s attorney in fact, and each and every one of Bank’s rights and powers, being coupled with an interest, is irrevocable until all of the Obligations
have been fully repaid and performed and Bank’s obligation to provide advances hereunder is terminated. 

9.3 Accounts Collection. At any time after the occurrence and during the continuation of an Event of Default, Bank
may notify any Person owing funds to Borrower of Bank’s security interest in such funds and verify 

  
 13 

 
the amount of such Account. Borrower shall collect all amounts owing to Borrower for Bank, receive in trust all payments as Bank’s trustee, and immediately deliver such payments to Bank in
their original form as received from the account debtor, with proper endorsements for deposit. 
 9.4 Bank
Expenses. If Borrower fails to pay any amounts or furnish any required proof of payment due to third persons or entities, as required under the terms of this Agreement, then Bank may do any or all of the following after reasonable notice to
Borrower: (a) make payment of the same or any part thereof; (b) set up such reserves under the Revolving Line as Bank deems necessary to protect Bank from the exposure created by such failure; or (c) obtain and maintain insurance
policies of the type discussed in Section 6.5 of this Agreement, and take any action with respect to such policies as Bank deems prudent. Any amounts so paid or deposited by Bank shall constitute Bank Expenses, shall be immediately due and
payable, and shall bear interest at the then applicable rate hereinabove provided, and shall be secured by the Collateral. Any payments made by Bank shall not constitute an agreement by Bank to make similar payments in the future or a waiver by Bank
of any Event of Default under this Agreement. 
 9.5 Bank’s Liability for Collateral. Bank has no
obligation to clean up or otherwise prepare the Collateral for sale. All risk of loss, damage or destruction of the Collateral shall be borne by Borrower. 
 9.6 No Obligation to Pursue Others. Bank has no obligation to attempt to satisfy the Obligations by collecting them from any other person liable for them and Bank may release, modify or waive any
collateral provided by any other Person to secure any of the Obligations, all without affecting Bank’s rights against Borrower. Borrower waives any right it may have to require Bank to pursue any other Person for any of the Obligations.

 9.7 Remedies Cumulative. Bank’s rights and remedies under this Agreement, the Loan Documents, and
all other agreements shall be cumulative. Bank shall have all other rights and remedies not inconsistent herewith as provided under the Code, by law, or in equity. No exercise by Bank of one right or remedy shall be deemed an election, and no waiver
by Bank of any Event of Default on Borrower’s part shall be deemed a continuing waiver. No delay by Bank shall constitute a waiver, election, or acquiescence by it. No waiver by Bank shall be effective unless made in a written document signed
on behalf of Bank and then shall be effective only in the specific instance and for the specific purpose for which it was given. Borrower expressly agrees that this Section 9.7 may not be waived or modified by Bank by course of performance,
conduct, estoppel or otherwise. 
 9.8 Demand; Protest. Except as otherwise provided in this Agreement,
Borrower waives demand, protest, notice of protest, notice of default or dishonor, notice of payment and nonpayment and any other notices relating to the Obligations. 
 10. NOTICES. 
 Unless otherwise provided in this Agreement,
all notices or demands by any party relating to this Agreement or any other agreement entered into in connection herewith shall be in writing and (except for financial statements and other informational documents which may be sent by first-class
mail, postage prepaid or as otherwise provided in this Agreement) shall be personally delivered or sent by a recognized overnight delivery service, certified mail, postage prepaid, return receipt requested, or by telefacsimile to Borrower or to

 11. CHOICE OF LAW AND VENUE; JURY TRIAL WAIVER. 

This Agreement shall be governed by, and construed in accordance with, the internal laws of the State of California,
without regard to principles of conflicts of law. Each of Borrower and Bank hereby submits to the exclusive jurisdiction of the State and Federal courts located in the State of California. THE UNDERSIGNED ACKNOWLEDGE THAT THE RIGHT TO TRIAL BY JURY
IS A CONSTITUTIONAL ONE, BUT THAT IT MAY BE WAIVED UNDER CERTAIN CIRCUMSTANCES. TO THE EXTENT PERMITTED BY LAW, EACH PARTY, AFTER CONSULTING (OR HAVING HAD THE OPPORTUNITY TO CONSULT) WITH COUNSEL OF ITS, HIS OR HER CHOICE, KNOWINGLY AND
VOLUNTARILY, AND FOR THE MUTUAL BENEFIT OF ALL PARTIES, WAIVES ANY RIGHT TO TRIAL BY JURY IN THE EVENT OF LITIGATION ARISING OUT OF OR RELATED TO THIS AGREEMENT OR ANY OTHER DOCUMENT, INSTRUMENT OR AGREEMENT BETWEEN THE UNDERSIGNED PARTIES.

 12. REFERENCE PROVISION. 
 12.1 In the event the Jury Trial Waiver set forth above is not enforceable, the parties elect to proceed under this Judicial Reference Provision. 

12.2 With the exception of the items specified in Section 12.3, below, any controversy, dispute or claim (each, a
“Claim”) between the parties arising out of or relating to this Agreement or any other document, instrument or agreement between the undersigned parties (collectively in this Section, the “Loan Documents”), will be resolved by a
reference proceeding in California in accordance with the provisions of Sections 638 et seq. of the California Code of Civil Procedure (“CCP”), or their successor sections, which shall constitute the exclusive remedy for the resolution of
any Claim, including whether the Claim is subject to the reference proceeding. Except as otherwise provided in the Loan Documents, venue for the reference proceeding will be in the Superior Court in the County where the real property involved in the
action, if any, is located or in a County where venue is otherwise appropriate under applicable law (the “Court”). 
 12.3 The matters that shall not be subject to a reference are the following: (i) nonjudicial foreclosure of any security interests in real or personal property, (ii) exercise of self-help
remedies (including, without limitation, set-off), (iii) appointment of a receiver and (iv) temporary, provisional or ancillary remedies (including, without limitation, writs of attachment, writs of possession, temporary restraining orders
or preliminary injunctions). This Agreement does not limit the right of any party to exercise or oppose any of the rights and remedies described in clauses (i) and (ii) or to seek or oppose from a court of competent jurisdiction any of the
items described in clauses (iii) and (iv). The exercise of, or opposition to, any of those items does not waive the right of any party to a reference pursuant to this Agreement. 

12.4 The referee shall be a retired Judge or Justice selected by mutual written agreement of the parties. If the parties
do not agree within ten (10) days of a written request to do so by any party, then, upon request of any party, the referee shall be selected by the Presiding Judge of the Court (or his or her representative). A request for appointment of a
referee may be heard on an ex parte or expedited basis, and the parties agree that irreparable harm would result if ex parte relief is not granted. 
 12.5 The parties agree that time is of the essence in conducting the reference proceedings. Accordingly, the referee shall be requested, subject to change in the time periods specified herein for good
cause shown, to (i) set the matter for a status and trial-setting conference within fifteen (15) days after the date of selection 

  
 15 

 
of the referee, (ii) if practicable, try all issues of law or fact within one hundred twenty (120) days after the date of the conference and (iii) report a statement of decision
within twenty (20) days after the matter has been submitted for decision. 
 12.6 The referee will have
power to expand or limit the amount and duration of discovery. The referee may set or extend discovery deadlines or cutoffs for good cause, including a party’s failure to provide requested discovery for any reason whatsoever. Unless otherwise
ordered based upon good cause shown, no party shall be entitled to “priority” in conducting discovery, depositions may be taken by either party upon seven (7) days written notice, and all other discovery shall be responded to within
fifteen (15) days after service. All disputes relating to discovery which cannot be resolved by the parties shall be submitted to the referee whose decision shall be final and binding. 

12.7 Except as expressly set forth in this Agreement, the referee shall determine the manner in which the reference
proceeding is conducted including the time and place of hearings, the order of presentation of evidence, and all other questions that arise with respect to the course of the reference proceeding. All proceedings and hearings conducted before the
referee, except for trial, shall be conducted without a court reporter, except that when any party so requests, a court reporter will be used at any hearing conducted before the referee, and the referee will be provided a courtesy copy of the
transcript. The party making such a request shall have the obligation to arrange for and pay the court reporter. Subject to the referee’s power to award costs to the prevailing party, the parties will equally share the cost of the referee and
the court reporter at trial. 
 12.8 The referee shall be required to determine all issues in accordance with
existing case law and the statutory laws of the State of California. The rules of evidence applicable to proceedings at law in the State of California will be applicable to the reference proceeding. The referee shall be empowered to enter equitable
as well as legal relief, enter equitable orders that will be binding on the parties and rule on any motion which would be authorized in a court proceeding, including without limitation motions for summary judgment or summary adjudication. The
referee shall issue a decision at the close of the reference proceeding which disposes of all claims of the parties that are the subject of the reference. Pursuant to CCP § 644, such decision shall be entered by the Court as a judgment or an
order in the same manner as if the action had been tried by the Court and any such decision will be final, binding and conclusive. The parties reserve the right to appeal from the final judgment or order or from any appealable decision or order
entered by the referee. The parties reserve the right to findings of fact, conclusions of laws, a written statement of decision, and the right to move for a new trial or a different judgment, which new trial, if granted, is also to be a reference
proceeding under this provision. 
 12.9 If the enabling legislation which provides for appointment of a referee
is repealed (and no successor statute is enacted), any dispute between the parties that would otherwise be determined by reference procedure will be resolved and determined by arbitration. The arbitration will be conducted by a retired judge or
Justice, in accordance with the California Arbitration Act §1280 through §1294.2 of the CCP as amended from time to time. The limitations with respect to discovery set forth above shall apply to any such arbitration proceeding. 

12.10 THE PARTIES RECOGNIZE AND AGREE THAT ALL CONTROVERSIES, DISPUTES AND CLAIMS RESOLVED UNDER THIS REFERENCE PROVISION
WILL BE DECIDED BY A REFEREE AND NOT BY A JURY. AFTER CONSULTING (OR HAVING HAD THE OPPORTUNITY TO CONSULT) WITH COUNSEL OF ITS, HIS OR HER OWN CHOICE, EACH PARTY KNOWINGLY AND VOLUNTARILY, AND FOR THE MUTUAL BENEFIT OF ALL PARTIES, AGREES THAT THIS
REFERENCE PROVISION WILL APPLY TO ANY CONTROVERSY, DISPUTE OR CLAIM BETWEEN OR AMONG THEM ARISING OUT OF OR IN ANY WAY RELATED TO, THIS AGREEMENT OR THE OTHER LOAN DOCUMENTS. 
 13. GENERAL PROVISIONS. 
 13.1 Successors and
Assigns. This Agreement shall bind and inure to the benefit of the respective successors and permitted assigns of each of the parties and shall bind all persons who become bound as a debtor to this Agreement; provided, however, that neither this
Agreement nor any rights hereunder may be assigned by Borrower without Bank’s prior written consent, which consent may be granted or withheld in Bank’s sole discretion. Bank shall have the right without the consent of or notice to Borrower

13.3 Time of Essence. Time is of the essence for the performance of all obligations set forth in this Agreement.

 13.8
Survival. All covenants, representations and warranties made in this Agreement shall continue in full force and effect so long as any Obligations remain outstanding or Bank has any obligation to make any Credit Extension to Borrower. The
obligations of Borrower to indemnify Bank with respect to the expenses, damages, losses, costs and liabilities described in Section 13.2 shall survive until all applicable statute of limitations periods with respect to actions that may be
brought against Bank have run. 
 13.9 Confidentiality. In handling any confidential information, Bank
and all employees and agents of Bank shall exercise the same degree of care that Bank exercises with respect to its own proprietary information of the same types to maintain the confidentiality of any non-public information thereby received or

 EXHIBIT B 
 COLLATERAL DESCRIPTION ATTACHMENT TO LOAN AND SECURITY AGREEMENT 
 All personal property of Debtor of every kind, whether presently existing or hereafter created or acquired, and wherever located, including but not limited to: (a) all accounts (including
health-care-insurance receivables), chattel paper (including tangible and electronic chattel paper), deposit accounts, documents (including negotiable documents), equipment (including all accessions and additions thereto), general intangibles
(including payment intangibles and software), goods (including fixtures), instruments (including promissory notes), inventory (including all goods held for sale or lease or to be furnished under a contract of service, and including returns and
repossessions), investment property (including securities and securities entitlements), letter of credit rights, money, and all of Debtor’s books and records with respect to any of the foregoing, and the computers and equipment containing said
books and records; and (b) any and all cash proceeds and/or noncash proceeds thereof, including, without limitation, insurance proceeds, and all supporting obligations and the security therefor or for any right to payment. All terms above have
the meanings given to them in the California Uniform Commercial Code, as amended or supplemented from time to time. 

Notwithstanding the foregoing, the Collateral shall not include any copyrights, patents, trademarks, servicemarks and applications
therefor, now owned or hereafter acquired, or any claims for damages by way of any past, present and future infringement of any of the foregoing (collectively, the “Intellectual Property”); provided, however, that the Collateral shall
include all accounts and general intangibles that consist of rights to payment from the sale, licensing or disposition of all or any part of, or rights in, the Intellectual Property (the “Rights to Payment”). Notwithstanding the foregoing,
if a judicial authority (including a U.S. Bankruptcy Court) holds that a security interest in the underlying Intellectual Property is necessary to have a security interest in the Rights to Payment, then the Collateral shall automatically, and
effective as of August 20, 2003, include the Intellectual Property to the extent necessary to permit perfection of Bank’s security interest in the Rights to Payment.

	 Note 1 -
	  	 Korean Bank debit is based on Korean Won. The balances included here have been translated at this exchange rate for the purposes of this summary. Actual $US
based payments may vary depending on the exchange rate in effect at the time of payment.

		
	 Note2 -
	  	 Total amount currently scheduled to be paid is based on estimates including the impact of accrued interest. That is the reason for the small variance between
the total of the schedule payments and the total debt outstanding.

 COLLATERAL DESCRIPTION
ATTACHMENT TO UCC NATIONAL FINANCING FORM 
 All personal property of Debtor of every kind, whether
presently existing or hereafter created or acquired, and wherever located, including but not limited to: (a) all accounts (including health-care-insurance receivables), chattel paper (including tangible and electronic chattel paper), deposit
accounts, documents (including negotiable documents), equipment (including all accessions and additions thereto), general intangibles (including payment intangibles and software), goods (including fixtures), instruments (including promissory notes),

 Prime Referenced Rate Addendum To 

Amended and Restated Loan and Security Agreement 

This Prime Referenced Rate Addendum to Amended and Restated Loan and Security Agreement (this “Addendum”) is
entered into as of April 4, 2011, by and between Comerica Bank (“Bank”) and GCT Semiconductor, Inc. (“Borrower”). This Addendum supplements the terms of the Amended and Restated Loan and Security Agreement
dated as of the date hereof (as the same may be amended, modified, supplemented, extended or restated from time to time, collectively, the “Agreement”), 
 1. Definitions. As used in this Addendum, the following terms shall have the following meanings. Initially capitalized terms used and not defined in this Addendum shall have the meanings ascribed
thereto in the Agreement, 
 a. “Applicable Margin” means one percent (1.00%) per annum.

 b. “Business Day” means any day, other than a Saturday, Sunday or any other day designated as a
holiday under Federal or applicable State statute or regulation, on which Bank is open for all or substantially all of its domestic and international business (including dealings in foreign exchange) in San Jose, California, and, in respect of
notices and determinations relating the Daily Adjusting LIBOR Rate, also a day on which dealings in dollar deposits are also carried on in the London interbank market and on which banks are open for business in London, England. 

c. “Daily Adjusting LIBOR Rate” means, for any day, a per annum interest rate which is equal to the quotient of
the following: 
  

	 	(1)	 for any day, the per annum rate of interest determined on the basis of the rate for deposits in United States Dollars for a period equal to one
(1) month appearing on Page BBAM of the Bloomberg Financial Markets Information Service as of 8:00 a.m. (California time) (or as soon thereafter as practical) an such day, or if such day is not a Business Day, on the immediately preceding
Business Day. In the event that such rate does not appear on Page BBAM of the Bloomberg Financial Markets Information Service (or otherwise on such Service) on any day, the “Daily Adjusting LIBOR Rate” for such day shall be determined by
reference to such other publicly available service for displaying eurodollar rates as may be reasonably selected by Bank, or in the absence of such other service, the “Daily Adjusting LIBOR Rate” for such day shall, instead, be determined
based upon the average of the rates at which Bank is offered dollar deposits at or about 8:00 a.m. (California time) (or as soon thereafter as practical), on such day, or if such day is not a Business Day, on the immediately preceding Business Day,
in the interbank eurodollar market in an amount comparable to the outstanding principal amount of the Obligations and for a period equal to one (1) month; 

divided by 
  

	 	(2)	 1.00 minus the maximum rate (expressed as a decimal) on such day at which Bank is required to maintain reserves on “Euro-currency
Liabilities” as defined in and pursuant to Regulation D of the Board of Governors of the Federal Reserve System or, if such regulation or definition is modified, and as long as Bank is required to maintain reserves against a category of
liabilities which includes eurodollar deposits or includes a category of assets which includes eurodollar loans, the rate at which such reserves are required to be maintained on such category. 

d. “LIBOR Lending Office” means Bank’s office located in the Cayman Islands, British West Indies, or such
other branch of Bank, domestic or foreign, as it may hereafter designate as its LIBOR Lending Office by notice to Borrower. 
 e. “Prime Rate” means the per annum interest rate established by Bank as its prime rate for its borrowers, as such rate may vary from time to time, which rate is not necessarily the lowest rate
on loans made by Bank at any such time, 
 f. “Prime Referenced Rate” means, for any day, a per annum
interest rate which is equal to the Prime Rate in effect on such day, but in no event and at no time shall the Prime Referenced Rate be less than the sum of the Daily Adjusting LIBOR Rate for such day plus two and one-half percent (2.50%) per
annum. If, at any time, Bank determines that it is unable to determine or ascertain 

  
 1 

 
the Daily Adjusting LIBOR Rate for any day, the Prime Referenced Rate for each such day shall be the Prime Rate in effect at such time, but not less than two and one-half percent (2.50%) per
annum. 
 2. Interest Rate. Subject to the terms and conditions of this Addendum, the Obligations under the Agreement
shall bear interest at the Prime Referenced Rate plus the Applicable Margin. 
 3. Payment of Interest. Accrued and
unpaid interest on the unpaid balance of the Obligations outstanding under the Agreement shall be payable monthly, in arrears, on the first day of each month, until maturity (whether as stated herein, by acceleration, or otherwise). In the event
that any payment under this Addendum becomes due and payable on any day which is not a Business Day, the due date thereof shall be extended to the next succeeding Business Day, and, to the extent applicable, interest shall continue to accrue and be
payable thereon during such extension at the rates set forth in this Addendum. interest accruing hereunder shall be computed on the basis of a year of 360 days, and shall be assessed for the actual number of days elapsed, and in such computation,
effect shall be given to any change in the applicable interest rate as a result of any change in the Prime Referenced Rate on the date of each such change. 
 4. Bank’s Records. The amount and date of each advance under the Agreement, its applicable interest rate, and the amount and date of any repayment shall be noted on Bank’s records, which
records shall be conclusive evidence thereof, absent manifest error; provided, however, any failure by Bank to make any such notation, or any error in any such notation, shall not relieve Borrower of its obligations to repay Bank all amounts payable
by Borrower to Bank under or pursuant to this Addendum and the Agreement, when due in accordance with the terms hereof. 
 5.
Default Interest Rate. From and after the occurrence of any Event of Default, and so long as any such Event of Default remains unremedied or uncured thereafter, the Obligations outstanding under the Agreement shall bear interest at a per
annum rate of five percent (5%) above the otherwise applicable interest rate hereunder, which interest shall be payable upon demand. In addition to the foregoing, a late payment charge equal to five percent (5%) of each late payment
hereunder may be charged on any payment not received by Bank within ten (10) calendar days after the payment due date therefor, but acceptance of payment of any such charge shall not constitute a waiver of any Event of Default under the
Agreement. In no event shall the interest payable under this Addendum and the Agreement at any time exceed the maximum rate permitted by law. 
 6. Prepayment. Borrower may prepay all or part of the outstanding balance of any Obligations at any time without premium or penalty. Any prepayment hereunder shall also be accompanied by the
payment of all accrued and unpaid interest on the amount so prepaid. Borrower hereby acknowledges and agrees that the foregoing shall not, in any way whatsoever, limit, restrict, or otherwise affect Bank’s right to make demand for payment of
all or any part of the Obligations under the Agreement due on a demand basis in Bank’s sole and absolute discretion. 
 7.
Regulatory Developments or Other Circumstances Relating to the Daily Adjusting LIBOR Rate. 
 a. If the
adoption after the date hereof, or any change after the date hereof in, any applicable law, rule or regulation (whether domestic or foreign) of any governmental authority, central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by Bank with any request or directive (whether or not having the force of law) made by any such authority, central bank or comparable agency after the date hereof: (a) shall subject Bank to any tax, duty or
other charge with respect to this Addendum or any Obligations under the Agreement, or shall change the basis of taxation of payments to Bank of the principal of or interest under this Addendum or any other amounts due under this Addendum in respect
thereof (except for changes in the rate of tax on the overall net income of Bank or its LIBOR Lending Office imposed by the jurisdiction in which Bank’s principal executive office or LIBOR Lending Office is located); or (b) shall impose,
modify or deem applicable any reserve (including, without limitation, any imposed by the Board of Governors of the Federal Reserve System), special deposit or similar requirement against assets of, deposits with or for the account of, or credit
extended by Bank, or shall impose on Bank or the foreign exchange and interbank markets any other condition affecting this Addendum or the Obligations hereunder; and the result of any of the foregoing is to increase the cost to Bank of maintaining
any part of the Obligations hereunder or to reduce the amount of any sum received or receivable by Bank under this Addendum by an amount deemed by the Bank to be material, then Borrower shall pay to Bank, within fifteen (15) days of
Borrower’s receipt of written notice from Bank demanding such compensation, such additional amount or amounts as will compensate Bank for such increased cost or reduction. A certificate of Bank, prepared in good faith and in reasonable detail
by Bank and submitted by Bank to Borrower, setting forth the basis for determining such additional amount or amounts necessary to compensate Bank shall be conclusive and binding for all purposes, absent manifest error. 

  
 2 

 b. In the event that any applicable law, treaty, rule or regulation (whether
domestic or foreign) now or hereafter in effect and whether or not presently applicable to Bank, or any interpretation or administration thereof by any governmental authority charged with the interpretation or administration thereof, or compliance
by Bank with any guideline, request or directive of any such authority (whether or not having the force of law), including any risk-based capital guidelines, affects or would affect the amount of capital required or expected to be maintained by Bank
(or any corporation controlling Bank), and Bank determines that the amount of such capital is increased by or based upon the existence of any obligations of Bank hereunder or the maintaining of any Obligations hereunder, and such increase has the
effect of reducing the rate of return on Bank’s (or such controlling corporation’s) capital as a consequence of such obligations or the maintaining of such Obligations hereunder to a level below that which Bank (or such controlling
corporation) could have achieved but for such circumstances (taking into consideration its policies with respect to capital adequacy), then Borrower shall pay to Bank, within fifteen (15) days of Borrower’s receipt of written notice from
Bank demanding such compensation, additional amounts as are sufficient to compensate Bank (or such controlling corporation) for any increase in the amount of capital and reduced rate of return which Bank reasonably determines to be allocable to the
existence of any obligations of the Bank hereunder or to maintaining any Obligations hereunder. A certificate of Bank as to the amount of such compensation, prepared in good faith and in reasonable detail by the Bank and submitted by Bank to the
undersigned, shall be conclusive and binding for all purposes absent manifest error. 
 8. Legal Effect. Except as
specifically modified hereby, all of the terms and conditions of the Agreement remain in full force and effect. 
 9.
Conflicts. As to the matters specifically the subject of this Addendum, in the event of any conflict between this Addendum and the Agreement, the terms of this Addendum shall control. 

IN WITNESS WHEREOF, the parties have agreed to the foregoing as of the date first set forth above.

 I may obtain the required insurance from any company that is acceptable to the Bank, and will deliver
proof of such coverage with an effective date of April 4, 2011 or earlier. 
 I understand and agree that if I fail to
deliver proof of insurance to the Bank at the address below, or upon the lapse or cancellation of such insurance, the Bank may procure Lender’s Single Interest Insurance or other similar coverage on the property, If the Bank procures insurance
to protect its interest in the property described in the security documents, the cost for the insurance will be added to my indebtedness as provided in the security documents, Lender’s Single Interest Insurance shall cover only the Bank’s
interest as a secured party, and shall become effective at the earlier of the funding date of this transaction or the date my insurance was canceled or expired. I UNDERSTAND THAT LENDER’S SINGLE INTEREST INSURANCE WILL PROVIDE ME WITH ONLY
LIMITED PROTECTION AGAINST PHYSICAL DAMAGE TO THE COLLATERAL, UP TO THE BALANCE OF THE LOAN, HOWEVER, MY EQUITY IN THE PROPERTY WILL NOT BE INSURED. FURTHER, THE INSURANCE WILL NOT PROVIDE MINIMUM PUBLIC LIABILITY OR PROPERTY DAMAGE INDEMNIFICATION
AND DOES NOT MEET THE REQUIREMENTS OF THE FINANCIAL RESPONSIBILITY LAW. 
 CALIFORNIA CIVIL CODE SECTION 2955.5, HAZARD
INSURANCE DISCLOSURE: No lender shall require a borrower, as a condition of receiving or maintaining a loan secured by real property, to provide hazard insurance coverage against risks to the improvements on that real property in an amount exceeding
the replacement value of the improvements on the property.

accommodation as Bank may deem advisable, Creditor is willing to subordinate: (i) all of Borrower’s indebtedness and obligations to Creditor, whether presently existing or arising in the future (the “Subordinated Debt”) to
all of Borrower’s indebtedness and obligations to Bank; and (ii) all of Creditor’s security interests, if any, to all of Bank’s security interests in the Borrower’s property. 

NOW, THEREFORE, THE PARTIES AGREE AS FOLLOWS: 

1. Creditor subordinates to Bank any security interest or lien that Creditor may have in any property of Borrower.
Notwithstanding the respective dates of attachment or perfection of the security interest of Creditor and the security interest of Bank, the security interest of Bank in the Collateral, as defined in that certain Amended and Restated Loan and
Security Agreement between Borrower and Bank, dated as of March 31, 2011 (as amended from time to time, the “Loan Agreement”), shall at all times be prior to the security interest of Creditor. 

2. All Subordinated Debt is subordinated in right of payment to all obligations of Borrower to Bank now existing or
hereafter arising, together with all costs of collecting such obligations (including attorneys’ fees), including, without limitation, all interest accruing after the commencement by or against Borrower of any bankruptcy, reorganization or
similar proceeding, and all obligations under the Loan Agreement (the “Senior Debt”). 
 3.
Creditor will not demand or receive from Borrower (and Borrower will not pay to Creditor) all or any part of the Subordinated Debt, by way of payment, prepayment, setoff, lawsuit or otherwise, nor will Creditor exercise any remedy with respect to
the Collateral, nor will Creditor commence, or cause to commence, prosecute or participate in any administrative, legal or equitable action against Borrower, for so long as any portion of the Senior Debt remains outstanding. 

4. Creditor shall promptly deliver to Bank in the form received (except for endorsement or assignment by Creditor where
required by Bank) for application to the Senior Debt any payment, distribution, security or proceeds received by Creditor with respect to the Subordinated Debt other than in accordance with this Agreement. 

5. In the event of Borrower’s insolvency, reorganization or any case or proceeding under any bankruptcy or
insolvency law or laws relating to the relief of debtors, these provisions shall remain in full force and effect, and Bank’s claims against Borrower and the estate of Borrower shall be paid in full before any payment is made to Creditor.

 6. For so long as any of the Senior Debt remains unpaid, Creditor irrevocably appoints Bank as
Creditor’s attorney in fact, and grants to Bank a power of attorney with full power of substitution, in the name of Creditor or in the name of Bank, for the use and benefit of Bank, without notice to Creditor, to perform at Bank’s option
the following acts in any bankruptcy, insolvency or similar proceeding involving Borrower: 
 (i)
To file the appropriate claim or claims in respect of the Subordinated Debt on behalf of Creditor if Creditor does not do so prior to 30 days before the expiration of the time to file claims in such proceeding and if Bank elects, in its sole
discretion, to file such claim or claims; and 

 (ii) To accept or reject any plan of reorganization or
arrangement on behalf of Creditor and to otherwise vote Creditor’s claims in respect of any Subordinated Debt in any manner that Bank deems appropriate for the enforcement of its rights hereunder. 

7. For so long as any of the Senior Debt remains unpaid, Creditor agrees that it will not object to or oppose
(i) the sale of the Borrower, or (ii) the sale or other disposition of any property of the Borrower, if Bank has consented to such sale of the Borrower or sale or disposition of any property of the Borrower. If requested by Bank, Creditor
shall affirmatively consent to such sale or disposition and shall take all necessary actions and execute such documents and instruments as Bank may reasonably request in connection with and to facilitate such sale or disposition. 

8. Creditor shall immediately affix a legend to the instruments evidencing the Subordinated Debt stating that the
instruments are subject to the terms of this Agreement. No amendment of the documents evidencing or relating to the Subordinated Debt shall directly or indirectly modify the provisions of this Agreement in any manner which might terminate or impair
the subordination of the Subordinated Debt or the subordination of the security interest or lien that Creditor may have in any property of Borrower. By way of example, such instruments shall not be amended to (i) increase the rate of interest
with respect to the Subordinated Debt, or (ii) accelerate the payment of the principal or interest or any other portion of the Subordinated Debt. 
 9. This Agreement shall remain effective for so long as Borrower owes any amounts to Bank under the Loan Agreement or otherwise. If, at any time after payment in full of the Senior Debt any payments of
the Senior Debt must be disgorged by Bank for any reason (including, without limitation, the bankruptcy of Borrower), this Agreement and the relative rights and priorities set forth herein shall be reinstated as to all such disgorged payments as
though such payments had not been made and Creditor shall immediately pay over to Bank all payments received with respect to the Subordinated Debt to the extent that such payments would have been prohibited hereunder. At any time and from time to
time, without notice to Creditor, Bank may take such actions with respect to the Senior Debt as Bank, in its sole discretion, may deem appropriate, including, without limitation, terminating advances to Borrower, increasing the principal amount,
extending the time of payment, increasing applicable interest rates, renewing, compromising or otherwise amending the terms of any documents affecting the Senior Debt and any collateral securing the Senior Debt, and enforcing or failing to enforce
any rights against Borrower or any other person. No such action or inaction shall impair or otherwise affect Bank’s rights hereunder. Creditor waives the benefits, if any, of Civil Code sections 2799, 2808, 2809, 2810, 2815, 2819, 2820, 2821,
2822, 2838, 2839, 2845, 2847, 2848, 2849, 2850, 2899 and 3433. 
 10. This Agreement shall bind any successors
or assignees of Creditor and shall benefit any successors or assigns of Bank. This Agreement is solely for the benefit of Creditor and Bank and not for the benefit of Borrower or any other party. Creditor further agrees that if Borrower is in the
process of refinancing a portion of the Senior Debt with a new lender, and if Bank makes a request of Creditor, Creditor shall agree to enter into a new subordination agreement with the new lender on substantially the terms and conditions of this
Agreement. 
 11. This Agreement may be executed in two or more counterparts, each of which shall be deemed an
original and all of which together shall constitute one instrument. 
 12. This Agreement shall be governed by
and construed in accordance with the laws of the State of California, without giving effect to conflicts of laws principles. Each of Creditor and Bank hereby submits to the exclusive jurisdiction of the state and Federal courts located in
California. THE UNDERSIGNED ACKNOWLEDGE THAT THE RIGHT TO TRIAL BY JURY IS A CONSTITUTIONAL ONE, BUT THAT IT MAY BE WAIVED UNDER CERTAIN CIRCUMSTANCES. TO THE EXTENT PERMITTED BY LAW, EACH PARTY, AFTER CONSULTING (OR HAVING HAD THE OPPORTUNITY TO
CONSULT) WITH COUNSEL OF ITS, HIS OR HER CHOICE, KNOWINGLY AND VOLUNTARILY, AND FOR THE MUTUAL BENEFIT OF ALL PARTIES, WAIVES ANY RIGHT TO TRIAL BY JURY IN THE EVENT OF LITIGATION ARISING OUT OF OR RELATED TO THIS AGREEMENT OR ANY OTHER DOCUMENT,
INSTRUMENT OR AGREEMENT BETWEEN THE UNDERSIGNED PARTIES. 
 13. JUDICIAL REFERENCE PROVISION. 

(a) In the event the Jury Trial Waiver set forth above is not enforceable, the parties elect to proceed
under this Judicial Reference Provision. 
 (b) With the exception of the items specified in
clause (c), below, any controversy, dispute or claim (each, a “Claim”) between the parties arising out of or relating to this Agreement or any other document, instrument or agreement between the undersigned parties (collectively in
this Section, the “Loan Documents”), will be resolved by a reference proceeding in California in accordance with the provisions of Sections 638 et seq. of the California Code of Civil Procedure (“CCP”), or their
successor sections, 

  
 2 

 
which shall constitute the exclusive remedy for the resolution of any Claim, including whether the Claim is subject to the reference proceeding. Except as otherwise provided in the Loan
Documents, venue for the reference proceeding will be in the Superior Court in the County where the real property involved in the action, if any, is located or in a County where venue is otherwise appropriate under applicable law (the
“Court”). 
 (c) The matters that shall not be subject to a reference are the
following: (i) nonjudicial foreclosure of any security interests in real or personal property, (ii) exercise of self-help remedies (including, without limitation, set-off), (iii) appointment of a receiver and (iv) temporary,
provisional or ancillary remedies (including, without limitation, writs of attachment, writs of possession, temporary restraining orders or preliminary injunctions). This Agreement does not limit the right of any party to exercise or oppose any of
the rights and remedies described in clauses (i) and (ii) or to seek or oppose from a court of competent jurisdiction any of the items described in clauses (iii) and (iv). The exercise of, or opposition to, any of those items does not
waive the right of any party to a reference pursuant to this Agreement. 
 (d) The referee shall
be a retired Judge or Justice selected by mutual written agreement of the parties. If the parties do not agree within ten (10) days of a written request to do so by any party, then, upon request of any party, the referee shall be selected by
the Presiding Judge of the Court (or his or her representative). A request for appointment of a referee may be heard on an ex parte or expedited basis, and the parties agree that irreparable harm would result if ex parte relief is not granted.

 (e) The parties agree that time is of the essence in conducting the reference proceedings.
Accordingly, the referee shall be requested, subject to change in the time periods specified herein for good cause shown, to (i) set the matter for a status and trial-setting conference within fifteen (15) days after the date of selection
of the referee, (ii) if practicable, try all issues of law or fact within one hundred twenty (120) days after the date of the conference and (iii) report a statement of decision within twenty (20) days after the matter has been
submitted for decision. 
 (f) The referee will have power to expand or limit the amount and
duration of discovery. The referee may set or extend discovery deadlines or cutoffs for good cause, including a party’s failure to provide requested discovery for any reason whatsoever. Unless otherwise ordered based upon good cause shown, no
party shall be entitled to “priority” in conducting discovery, depositions may be taken by either party upon seven (7) days written notice, and all other discovery shall be responded to within fifteen (15) days after service. All
disputes relating to discovery which cannot be resolved by the parties shall be submitted to the referee whose decision shall be final and binding. 

(g) Except as expressly set forth in this Agreement, the referee shall determine the manner in which the
reference proceeding is conducted including the time and place of hearings, the order of presentation of evidence, and all other questions that arise with respect to the course of the reference proceeding. All proceedings and hearings conducted
before the referee, except for trial, shall be conducted without a court reporter, except that when any party so requests, a court reporter will be used at any hearing conducted before the referee, and the referee will be provided a courtesy copy of
the transcript. The party making such a request shall have the obligation to arrange for and pay the court reporter. Subject to the referee’s power to award costs to the prevailing party, the parties will equally share the cost of the referee
and the court reporter at trial. 
 (h) The referee shall be required to determine all issues in
accordance with existing case law and the statutory laws of the State of California. The rules of evidence applicable to proceedings at law in the State of California will be applicable to the reference proceeding. The referee shall be empowered to
enter equitable as well as legal relief, enter equitable orders that will be binding on the parties and rule on any motion which would be authorized in a court proceeding, including without limitation motions for summary judgment or summary
adjudication. The referee shall issue a decision at the close of the reference proceeding which disposes of all claims of the parties that are the subject of the reference. Pursuant to CCP § 644, such decision shall be entered by the Court as a
judgment or an order in the same manner as if the action had been tried by the Court and any such decision will be final, binding and conclusive. The parties reserve the right to appeal from the final judgment or order or from any appealable
decision or order entered by the referee. The parties reserve the right to findings of fact, conclusions of laws, a written statement of decision, and the right to move for a new trial or a different judgment, which new trial, if granted, is also to
be a reference proceeding under this provision. 
 (i) If the enabling legislation which provides
for appointment of a referee is repealed (and no successor statute is enacted), any dispute between the parties that would otherwise be determined by reference procedure will be resolved and determined by arbitration, The arbitration will be
conducted by a retired judge or Justice, in accordance with the California Arbitration Act § 1280 through § 1294,2 of the CCP as amended from time to time. The limitations with respect to discovery set forth above shall apply to any such
arbitration proceeding. 

  
 3 

 (j) THE PARTIES RECOGNIZE AND AGREE THAT ALL CONTROVERSIES,
DISPUTES AND CLAIMS RESOLVED UNDER THIS REFERENCE PROVISION WILL BE DECIDED BY A REFEREE AND NOT BY A JURY. AFTER CONSULTING (OR HAVING HAD THE OPPORTUNITY TO CONSULT) WITH COUNSEL OF ITS, HIS OR HER OWN CHOICE, EACH PARTY KNOWINGLY AND VOLUNTARILY,
AND FOR THE MUTUAL BENEFIT OF ALL PARTIES, AGREES THAT THIS REFERENCE PROVISION WILL APPLY TO ANY CONTROVERSY, DISPUTE OR CLAIM BETWEEN OR AMONG THEM ARISING OUT OF OR IN ANY WAY RELATED TO, THIS AGREEMENT OR THE OTHER LOAN DOCUMENTS. 

14. This Agreement represents the entire agreement with respect to the subject matter hereof, and supersedes all prior
negotiations, agreements and commitments. Creditor is not relying on any representations by Bank or Borrower in entering into this Agreement, and Creditor has kept and will continue to keep itself fully apprised of the financial and other condition
of Borrower. This Agreement may be amended only by written instrument signed by Creditor and Bank. 
 15. In the
event of any legal action to enforce the rights of a party under this Agreement, the party prevailing in such action shall be entitled, in addition to such other relief as maybe granted, all reasonable costs and expenses, including reasonable
attorneys’ fees, incurred in such action.
