 (b) Late Fee; Default Rate. If any payment is not made within ten (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 applicable immediately prior to the occurrence of the Event of Default. 
  
 (c) Payments. Interest hereunder shall be due and payable on the last 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 Equipment 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, except that to the extent Borrower uses the Equipment Advances to purchase Collateral, Borrower’s repayment of the Equipment Advances shall apply on a
“first-in-first-out” basis so that the portion of the Equipment Advances used to purchase a particular item of Collateral shall be paid in the chronological order the Borrower purchased the Collateral. 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.

shall pay to Bank the following: 
  
 (a)

 2.6 Term. This Agreement shall become effective on
the Closing Date and, subject to Section 13.7, 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.

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 signed by Bank on behalf of Borrower, as provided in the Code, and may
be filed 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 perfected 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;
provided, however, that where Collateral is in possession of a third party bailee, Borrower shall take such steps as Bank reasonably requests for Bank to obtain an acknowledgment, in form and substance satisfactory to Bank, of the bailee that the
bailee holds such Collateral for the benefit of Bank. 
  
 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 duly existing under the laws of the state 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 Articles of Incorporation or Bylaws, 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 could 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. All Collateral is located solely in the Collateral Locations. 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 Intentionally Omitted. 
  
 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 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 Litigation. Except as set forth in the Schedule, there are no actions or proceedings pending by or against Borrower or any
Subsidiary before any court or administrative agency 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 capital after the transactions contemplated by this Agreement. 
  
 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 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 could reasonably be expected to have a Material Adverse
Effect. Borrower and each Subsidiary have filed or caused to be filed all tax returns required to be filed, and have paid, or have made adequate provision for the payment of, all taxes reflected therein except those being contested in good faith
with adequate reserves under GAAP or where the failure to file such returns or pay such taxes could not reasonably be expected to have a Material Adverse Effect. 
  
 5.10 Subsidiaries. Borrower does not own any stock, partnership interest or other equity securities
of any Person, except for Permitted Investments. 
  
 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 could not reasonably be expected to cause a Material Adverse Effect. 
  
 5.12 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 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 and agrees that, until payment in full of all outstanding Obligations, and for so long as Bank may have any commitment to make a Credit

standing in each other jurisdiction in which the failure to so qualify could have a Material Adverse Effect, and shall furnish to Bank the organizational identification number issued to Borrower by the authorities of the state in which Borrower is
organized, if applicable. Borrower shall meet, and shall cause each Subsidiary to meet, the minimum funding requirements of ERISA with respect to any employee benefit plans subject to ERISA. 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 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 could reasonably be expected to have a Material Adverse Effect.

  
 6.2 Financial Statements, Reports,
Certificates. Borrower shall deliver the following to Bank: (i) as soon as available, but in any event within thirty (30) days after the end of each calendar quarter (or, thirty (30) days after the end of each calendar month, when

 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

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

 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 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

and the aggregate outstanding amount of Equipment Advances and shall execute such documents as Bank may request to effect such pledge; and (ii) thereafter, no further Equipment Advances will be made unless such Equipment Advances are cash
secured as described in subsection (i) above. 
  
 6.8 Further Assurances. At any time and from time to time Borrower shall execute and deliver such further instruments and take such further action as may reasonably be requested by Bank to effect the purposes of this Agreement.

another Person except where (i) such transactions do not in the aggregate exceed Ten Million Dollars ($10,000,000) in cash consideration during any fiscal year, (ii) no Event of Default has occurred, is continuing or would exist after
giving effect to such transactions, (iii) such transactions do not result in a Change in Control, and (iv) Borrower is the surviving entity.

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.

agreement that restricts such Subsidiary from paying dividends or otherwise distributing property to Borrower. 
  
 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.

property. 
  

	 	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
Article 6 or violates any of the covenants contained in Article 7 of this Agreement; or

ten (10) 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 ten (10) day period or cannot after diligent attempts by
Borrower be cured within such ten (10) day period, and such default is likely to be cured within a reasonable time, then Borrower shall have an additional reasonable period (which shall not in any case exceed thirty (30) days) to 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;

 8.7 Other Agreements. If there is a default or other failure to perform in any agreement 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 Million Dollars ($1,000,000) or that could have a Material Adverse Effect;

	 	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, 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, as collateral security for the repayment of any future drawings under such Letters of Credit, 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, 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) 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 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; 
  
 (e) 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; 
  
 (f) 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; 
  

(g) 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; 

 (h) Bank may credit bid and purchase at any public sale; 
  
 (i) 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 
  
 (j) 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) dispose of any
Collateral; (b) make, settle, and adjust all claims under and decisions with respect to Borrower’s policies of insurance related to the Collateral; (c) settle and adjust disputes and claims respecting the accounts directly with
account debtors related to the Collateral, for amounts and upon terms which Bank determines to be reasonable; and (d) to 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 (d) 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 Credit Extensions hereunder is terminated. 
  
 9.3 Intentionally Omitted. 
  
 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 Equipment 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 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.

	 	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 County of San Diego, State of California. BANK AND BORROWER EACH ACKNOWLEDGE THAT THE RIGHT TO TRIAL BY JURY IS A
CONSTITUTIONAL ONE, BUT THAT IT MAY BE WAIVED. EACH OF THEM, AFTER CONSULTING OR HAVING HAD THE OPPORTUNITY TO CONSULT, WITH COUNSEL OF THEIR CHOICE, KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVES ANY RIGHT ANY OF THEM MAY HAVE TO A TRIAL BY JURY
IN ANY LITIGATION BASED UPON OR ARISING OUT OF THIS AGREEMENT OR ANY RELATED INSTRUMENT OR LOAN DOCUMENT OR ANY OF THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT OR ANY COURSE OF CONDUCT, DEALING, STATEMENTS (WHETHER ORAL OR WRITTEN), OR ACTION OF
ANY OF THEM. THESE PROVISIONS SHALL NOT BE DEEMED TO HAVE BEEN MODIFIED IN ANY RESPECT OR RELINQUISHED BY BANK OR BORROWER, EXCEPT BY A WRITTEN INSTRUMENT EXECUTED BY EACH OF THEM. 
  

	 	12.	REFERENCE PROVISION. 

  
 If and only if the jury trial waiver set forth in Section 11 of this Agreement is invalidated for any reason by a court of law, statute or otherwise,
the reference provisions set forth below shall be substituted in place of the jury trial waiver. So long as the jury trial waiver remains valid, the reference provisions set forth in this Section shall be inapplicable. 

 12.1 Mechanics. 
  
 (a) Other than (i) nonjudicial foreclosure of security interests in real or personal property,
(ii) the appointment of a receiver or (iii) the exercise of other provisional remedies (any of which may be initiated pursuant to applicable law), 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 Bank and the undersigned (collectively in this Section, the “Loan Documents”), will be resolved by a reference proceeding in California in
accordance with the provisions of Section 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 or Federal District Court in the County or District where venue is otherwise
appropriate under applicable law (the “Court”). 
  
 (b) The referee shall be a retired Judge or Justice selected by mutual written agreement of the parties. If the parties do not agree, 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. The referee shall be appointed to sit with all the
powers provided by law. Each party shall have one peremptory challenge pursuant to CCP §170.6. Pending appointment of the referee, the Court has power to issue temporary or provisional remedies. 
  
 (c) The parties agree that time is of the essence in
conducting the reference proceedings. Accordingly, the referee shall be requested to (a) set the matter for a status and trial-setting conference within fifteen (15) days after the date of selection of the referee, (b) if practicable,
try all issues of law or fact within ninety (90) days after the date of the conference and (c) report a statement of decision within twenty (20) days after the matter has been submitted for decision. Any decision rendered by the
referee will be final, binding and conclusive, and judgment shall be entered pursuant to CCP §644. 
  
 (d) 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, 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. 
  
 12.2 Procedures. 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. 
  
 12.3 Application of Law. 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, provide all temporary or provisional remedies, enter equitable orders that will be binding on the parties and rule on any motion which would be authorized in a trial, 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. The referee’s 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. 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. 
  
 12.4
Repeal. 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. 
  
 12.5 THE PARTIES RECOGNIZE AND AGREE THAT ALL DISPUTES RESOLVED UNDER THIS REFERENCE PROVISION WILL BE DECIDED BY A REFEREE AND NOT BY A JURY, AND THAT THEY ARE IN EFFECT WAIVING THEIR RIGHT TO TRIAL BY JURY IN
AGREEING TO THIS REFERENCE PROVISION. AFTER CONSULTING (OR HAVING HAD THE OPPORTUNITY TO CONSULT) WITH COUNSEL OF THEIR OWN CHOICE, EACH PARTY KNOWINGLY AND VOLUNTARILY AND FOR THEIR MUTUAL BENEFIT AGREES THAT THIS REFERENCE PROVISION WILL APPLY TO
ANY DISPUTE BETWEEN THEM WHICH ARISES OUT OF OR IS RELATED TO THIS AGREEMENT OR THE 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 to sell, transfer, negotiate, or grant participation in all or any part of, or any interest in, Bank’s
obligations, rights and benefits hereunder. 
  
 13.2 Indemnification. Borrower shall defend, indemnify and hold harmless Bank and its officers, employees, and agents against: (a) all obligations, demands, claims, and liabilities claimed or asserted by any other party in
connection with the transactions contemplated by this Agreement; and (b) all losses or Bank Expenses in any way suffered, incurred, or paid by Bank, its officers, employees and agents as a result of or in any way arising out of, following, or
consequential to transactions between Bank and Borrower whether under this Agreement, or otherwise (including without limitation reasonable attorneys’ fees and expenses), except for losses caused by Bank’s gross negligence or willful
misconduct. 
  
 13.3 Time of Essence. Time
is of the essence for the performance of all obligations set forth in this Agreement. 
  
 13.4 Severability of Provisions. Each provision of this Agreement shall be severable from every other provision of this Agreement
for the purpose of determining the legal enforceability of any specific provision. 
  
 13.5 Amendments in Writing, Integration. All amendments to or terminations of this Agreement or the other Loan Documents must be in

Loan Documents. 
  
 13.6 Counterparts.
This Agreement may be executed in any number of counterparts and by different parties on separate counterparts, each of which, when executed and delivered, shall be deemed to be an original, and all of which, when taken together, shall constitute
but one and the same Agreement. 
  
 13.7
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. 
  
 13.8 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 received pursuant to this Agreement except that disclosure of such information may be made (i) to the subsidiaries or Affiliates of Bank in connection with their
present or prospective business relations with Borrower, (ii) to prospective transferees or purchasers of any interest in the Loans, provided that they have entered into a comparable confidentiality agreement in favor of Borrower and have
delivered a copy to Borrower, (iii) as required by law, regulations, rule or order, subpoena, judicial order or similar order, (iv) as may be required in connection with the examination, audit or similar investigation of Bank and
(v) as Bank may determine in connection with the enforcement of any remedies hereunder. Confidential information hereunder shall not include information that either: (a) is in the public domain or in the knowledge or possession of Bank
when disclosed to Bank, or becomes part of the public domain after disclosure to Bank through no fault of Bank; or (b) is disclosed to Bank by a third party, provided Bank does not have actual knowledge that such third party is prohibited from
disclosing such information.

 (US District Court for Southern District of New York)
	  	 	 
		
	 From Borrower’s most recently filed 10-Q:
	  	 	 

  
 In December 2002, we and certain of
our officers and directors were named as defendants in a class action shareholder complaint filed in the United States District Court for the Southern District of New York, now captioned In re Diversa Corp. Initial Public Offering Sec. Litig., Case
No. 02-CV-9699. In the amended complaint, the plaintiffs allege that we and certain of our officers and directors, and the underwriters (the “Underwriters”) of our initial public offering (“the IPO”), violated Sections 11
and 15 of the Securities Act of 1933, as amended, based on allegations that our registration statement and prospectus prepared in connection with our IPO failed to disclose material facts regarding the compensation to be received by, and the stock
allocation practices of, the Underwriters. The complaint also contains claims for violation of Sections 10(b) and 20 of the Exchange Act based on allegations 

 
that this omission constituted a deceit on investors. The plaintiffs seek unspecified monetary damages and other relief. This action is related to In re
Initial Public Offering Sec. Litig., Case No. 21 MC 92, in which similar complaints were filed by plaintiffs (the “Plaintiffs”) against hundreds of other public companies (collectively, the “Issuers”) that conducted IPOs of
their common stock in the late 1990s and 2000 (collectively, the “IPO Cases”). On January 7, 2003, the IPO Case against us was assigned to United States Judge Shira Scheindlin of the Southern District of New York, before whom the IPO
Cases have been consolidated for pretrial purposes. 
  
 In February 2003, the
Court issued a decision denying the motion to dismiss the Sections 11 and 15 claims against us and our officers and directors, and granting the motion to dismiss the Section 10(b) claim against us without leave to amend. The Court similarly
dismissed the Sections 10(b) and 20 claims against two of our officers and directors without leave to amend, but denied the motion to dismiss these claims against one officer/director. 
  
 In June 2003, Issuers and Plaintiffs reached a tentative settlement agreement and entered into a memorandum of understanding providing for,
among other things, a dismissal with prejudice and full release of the Issuers and their officers and directors from all further liability resulting from Plaintiffs’ claims, and the assignment to Plaintiffs of certain potential claims that the
Issuers may have against the Underwriters. The tentative settlement also provides that, in the event that Plaintiffs ultimately recover less than a guaranteed sum of $1 billion from the Underwriters in the IPO Cases and related litigation,
Plaintiffs would be entitled to payment by each participating Issuer’s insurer of a pro rata share of any shortfall in the Plaintiffs’ guaranteed recovery. In the event, for example, that Plaintiffs recover nothing from the Underwriter
defendants in the IPO Cases and the Issuers’ insurers therefore become liable to the Plaintiffs for an aggregate of $1 billion pursuant to the settlement proposal, the pro rata liability of our insurers, with respect to us, would be
approximately $4 million, assuming that 250 participate in the settlement. We are covered by a claims-made liability insurance policy which we believe would satisfy our insurer’s pro rata liability described in this hypothetical example.

  
 In June 2004, we executed a formal settlement agreement with the plaintiffs
pursuant to the terms of the memorandum of understanding. On February 15, 2005, the Court issued a decision certifying a class action for settlement purposes and granting preliminary approval of the settlement subject to modification of certain
bar orders contemplated by the settlement. In addition, the settlement is still subject to statutory notice requirements and final judicial approval

 Exhibit 10.18 
  
 

 
  
 August 16th, 2005 
  
 Dear Ms. Tilghman, 
  
 Google Inc. (the “Company”) is pleased to offer you a position as a member of the Company’s Board of
Directors (the “Board”) effective as of the date of our next regularly-scheduled Board meeting, currently expected to be September 30, 2005. What follows is some information on the benefits available to you as a director of the
Company (a “Director”). 
  
 As compensation for your
services to the Company, you will be granted two initial equity grants. The first grant will be an option to purchase 12,000 shares of Google Class A common stock. This will be a non-qualified stock option with an exercise price equal to
the closing fair market value of the underlying stock on the date of grant. The shares underlying the option will vest at the rate of 1/5th on the date one year after you commence service as a Director and an additional 1/60th each month thereafter, subject to your continued service as a Director on the applicable vesting date. The second grant will be in the form of 6,000 Google Stock Units (GSUs). Each GSU will entitle you to one
share of Google Class A common stock when the GSU vests. Your GSUs will vest at the rate of 1/5th on the
date one year after you commence service as a Director and an additional 1/20th each quarter thereafter, subject to
your continued service as a Director on the applicable vesting date. Board grants take place on the first business day of the month following the date on which the Board approves the grant and you commence service on the Board. The option and
GSUs shall be subject to the terms and conditions of the Company’s 2004 Stock Plan and their respective grant agreements, all of which documents are incorporated herein by reference. 
  
 You shall also be reimbursed for all reasonable expenses incurred by you in connection with your services to the Company,
including reimbursement for first-class air travel. If on occasion commercial air travel makes attending Company business impractical, then the Company will pay for your reasonable travel expenses via private aircraft. All expense reimbursements are
in accordance with established Company policies. 
  
 Board
meetings are generally held on site at the Company quarterly and we would hope that your schedule would permit you to attend all of the meetings. In addition, there may be telephonic calls to address special projects that arise from time to time.
The Board has delegated certain duties to other committees, which you may be asked participate on. 
  
 Nothing in this offer or the stock option agreement should be construed to interfere with or otherwise restrict in any way the rights of the Company and
the Company’s stockholders to remove any individual from the Board at any time in accordance with the provisions of applicable law. 

 This letter sets forth the terms of your service with the Company and supersedes any prior
representations or agreements, whether written or oral. This letter may not be modified or amended except by a written agreement, signed by an officer of the Company and by you. 
  
 We hope that you find the foregoing terms acceptable. You may indicate your agreement with these terms and accept this offer
by signing and dating both the enclosed duplicate and original letter and returning them to me. 
  
 Shirley, I am looking forward to you joining the Company’s Board of Directors. I believe you will make a significant contribution to the Company and
will help us to navigate our way through the future direction of the Company. 
  
 Sincerely, 
  
 Google Inc. 
  
 /s/ John L. Hennessey
