EXECUTION VERSION

THIS LOAN AND SECURITY AGREEMENT dated as of May 21, 2014 (“Agreement”), made by and between VIKING THERAPEUTICS, INC., a Delaware corporation (“Borrower”), and LIGAND PHARMACEUTICALS INCORPORATED, a Delaware corporation (“Lender”), provides the terms on which the Lender shall lend to Borrower and Borrower shall repay the Lender.

1.Defined Terms. As used in this Agreement, unless otherwise defined, the capitalized terms shall have the meanings set forth in Schedule A.

2. Loans and Terms of Payment and/or Conversion.

(a) Promise to Pay. Borrower hereby unconditionally promises to pay Lender the outstanding principal amount of all Loans advanced to Borrower by Lender and accrued and unpaid interest thereon and any other amounts due hereunder as and when due in accordance with this Agreement.

(b) Loans. Subject to the terms and conditions of this Agreement, the Lender agrees to make loans to Borrower in an aggregate amount of Two Million Five Hundred Thousand Dollars ($2,500,000.00) (such loans are hereinafter referred to singly as a “Loan”, and collectively as the “Loans”). After repayment by Borrower, no Loan may be reborrowed.

(i) Upon the consummation of the earlier to occur of a Qualified Private Financing or an Initial Public Offering (the first to occur, an “Equity Financing”), the Lender shall, at its sole option and discretion, elect to either, in an irrevocable writing delivered to Borrower, (a) receive that number of fully paid and nonassessable shares of Borrower Equity as is equal to 200% of the quotient obtained by dividing the entire principal amount of the Loans then outstanding plus all accrued and previously unpaid interest thereon by the lowest per share price paid by investors in the Equity Financing, rounded down to the nearest whole share (the “Conversion Shares”), or (b) require the Borrower to prepay the entire then outstanding principal amount of the Loans plus all accrued and previously unpaid interest thereon in cash equal to an amount that shall equal 200% of the principal amount of the Loans then outstanding plus all accrued and previously unpaid interest thereon (“Prepayment”); provided, however, if the first to occur Equity Financing is a Qualified Private Financing, the Lender may also elect to extend the Maturity Date, at its sole option and discretion, to a date to be agreed upon by Borrower and Lender in writing.

(ii) Upon the occurrence of a Change of Control prior to the earlier of the occurrence of either (a) the Maturity Date or (b) the closing of the Equity Financing, the Lender shall, at its sole option and discretion, elect to either, in an irrevocable writing delivered to Borrower, (I) receive that number of fully paid and nonassessable shares of the Borrower’s securities, as is equal to 200% of the quotient obtained by dividing the entire principal amount of the Loans then outstanding plus all accrued and previously unpaid interest thereon by the lower of (A) the deemed Common Stock per share price used to calculate the purchase price paid by the acquirer of Borrower in such Change of Control or (B) the lowest per share price paid by investors for shares of New

Preferred prior to the Change of Control (if New Preferred has been issued prior to the Change of Control), in each case rounded down to the nearest whole share, or (II) require the Borrower to make the Prepayment. The Borrower’s securities to be issued in connection with a Change of Control shall be New Preferred (if New Preferred has been issued prior to the Change of Control) or Common Stock, par value $0.00001 per share, of the Borrower (“Common Stock”) (if no New Preferred has been issued prior to the occurrence of the Change of Control) (“Change of Control Securities”).

(d) Mechanics of Conversion.

(i) Notice to Lender. The Borrower shall promptly, but in all events at least [***] days prior to consummation of an Equity Financing or [***] days prior to the consummation of a Change of Control, as applicable, deliver to the Lender written notification of the proposed consummation of an Equity Financing or a Change of Control, as applicable, which notice shall describe the material terms and conditions of such Equity Financing or Change of Control (“Notice of Transaction”), and the Lender shall have [***] days from the date of such notice to elect, by written notice to the Borrower, to convert the Loans or require the Prepayment, which election shall be irrevocable and may be made contingent on the closing of the Equity Financing or Change of Control, as applicable. The Borrower shall include in the Notice of Transaction the number of voting securities of the Borrower anticipated to be issued and outstanding following the consummation of the Equity Financing or immediately prior to the Change of Control.

(ii) Stock Certificates. The Borrower shall, as soon as practicable following consummation of an Equity Financing or Change of Control for which Lender has elected to convert the Loans as permitted hereunder, issue and deliver to the Lender, or to its nominee or nominees, a certificate or certificates for the number of shares of Borrower Securities to which it shall be entitled as aforesaid. Such conversion shall be deemed to have been made, as applicable, immediately prior to the close of business on the date of the closing of the Equity Financing or the Change of Control, as applicable. The person or persons entitled to receive the Borrower Securities issuable upon such conversion shall be treated for all purposes as the record holders of such Borrower Securities on such date.

(iii) Registration of Borrower Securities Issued Hereunder. Concurrently with the execution of this Agreement, Borrower and Lender and an Affiliate of Lender are entering into a Registration Rights Agreement, dated as of even date herewith.

(iv) Charges, Taxes and Expenses. Issuance of a certificate for shares of Borrower Securities upon conversion of the Loans shall be made without charge to the Lender for any issue or transfer tax or other incidental expense in respect of the issuance of such certificate, all of which taxes and expenses shall be paid by the Borrower, and such certificate shall be issued in the name of the Lender, or such certificates shall be issued in such name or names as may be directed by the Lender. The Lender shall execute such documents, and perform such acts, which are reasonably required to assure that the conversion hereof is consummated in compliance with all applicable laws.

(v) No Rights as Stockholder. The conversion rights set forth in this Agreement do not entitle the Lender to any voting rights or other rights as a stockholder of the Borrower prior to the conversion of the Loans into Borrower Securities pursuant to the terms of this Agreement.

(vi) Restricted Securities. The Lender acknowledges that the Borrower Securities acquired upon the conversion of the Loan will be subject to restrictions upon resale imposed by state and federal securities laws and may be subject to transfer restrictions set forth in the Borrower’s bylaws or in one or more agreements that may be entered into by and among the Borrower, the Lender and the holders of the Borrower Securities.

(e) Repayment. The Loan will automatically mature and the entire outstanding principal amount, together with accrued interest, shall become due and payable upon written demand by the Lender, which demand may be made at any time after the Maturity Date, unless, prior to such time, the Loan shall have been converted into Borrower’s Equity pursuant to Section 2(c). The Loan may only be prepaid in accordance with Section 2.

(f) Interest Rate; Default Rate. Subject to this Section 2(f), the principal amount outstanding under the Loans shall accrue interest at a fixed per annum rate of the lesser of (a) five percent (5.0%) and (b) the maximum interest rate permitted by law, which interest shall accrue on each Loan commencing on, and including, the funding date of such Loan (the “Funding Date”), and shall accrue on the principal amount outstanding under such Loan through and including the day on which such Loan is paid (or converted into Borrower Securities) in full. Interest shall be computed on the basis of a three hundred sixty (360) day year consisting of twelve (12) months of thirty (30) days. Upon the occurrence and during the continuance of an Event of Default and upon written notice to the Borrower from the Lender, Obligations shall accrue interest at a fixed per annum rate of the lesser of (a) eight percent (8%) and (b) the maximum interest rate permitted by law (the “Default Rate”). Payment or acceptance of the increased interest rate provided in this Section 2(f) is not a permitted alternative to timely payment and shall not constitute a waiver of any Event of Default or otherwise prejudice or limit any rights or remedies of Borrower.

(g) Cash Payments. Except as otherwise expressly provided herein, all cash payments by Borrower under this Agreement or under any other Loan Document, including payments of principal and interest, and all fees, expenses, indemnities and reimbursements, shall be made to the Lender at Lender’s office in immediately available funds on the date specified herein. All cash payments to be made by Borrower hereunder or under any other Loan Document, including payments of principal and interest, and all fees, expenses, indemnities and reimbursements, shall be made without set off, recoupment or counterclaim, in lawful money of the United States and in immediately available funds.

(h) Withholding. Payments received by the Lender from Borrower hereunder will be made free and clear of and without deduction for any and all present or future taxes, levies, imposts, duties, deductions, withholdings, assessments, fees or other charges imposed by any governmental authority (including any interest, additions to tax or penalties applicable thereto), except as required by law.

3. Secured Promissory Note. The Loans shall be evidenced by a Secured Convertible Promissory Note in the form attached as Exhibit A hereto (a “Secured Promissory Note”), and shall be repayable or converted into Borrower Securities as set forth in this Agreement. Borrower irrevocably authorizes the Lender to make or cause to be made, on or about the Funding Date or at the time of receipt of any payment of principal, an appropriate notation on the Secured Promissory Note Record reflecting the making of such Loan or (as the case may be) the receipt of such payment. The outstanding amount of each Loan set forth on the Secured Promissory Note Record shall be prima facie evidence of the principal amount thereof owing and unpaid to the Lender (absent manifest error), but the failure to record, or any error in so recording (other than manifest error), any such amount on the Secured Promissory Note Record shall not limit or otherwise affect the obligations of Borrower under the Secured Promissory Note or any other Loan Document to make payments of principal of or interest on any Secured Promissory Note when due. Upon receipt of an affidavit of an officer of a Lender and a customary indemnification agreement, in a form reasonably acceptable to Borrower, as to the loss, theft, destruction, or mutilation of its Secured Promissory Note, Borrower shall issue, in lieu thereof, a replacement Secured Promissory Note in the same principal amount thereof and of like tenor.

4. Conditions Precedent to Loan.

(a) Lender’s obligation to make the initial Loan is subject to the condition precedent that the Lender shall have received, in form and substance reasonably satisfactory to Lender, such documents and evidence of completion of such other matters, as Lender may reasonably deem necessary in connection herewith, including, without limitation:

The Borrower shall take such steps as may be reasonably requested by the Lender to ensure that the security interest of the Lender is registered with each such recording office.

(i) Certificated Security, Chattel Paper or Instrument. With respect to any Collateral that is evidenced by, or constitutes, a Certificated Security, Chattel Paper or Instrument (other than any Chattel Paper or Instruments having a value less than [***] individually or [***] in the aggregate), the Borrower shall cause each originally executed copy thereof to be delivered to the Lender (or its agent or designee) appropriately endorsed to the Lender or endorsed in blank: (i) with respect to any such Collateral in existence on the date hereof, on or prior to the date hereof and (ii) with respect to any such Collateral hereafter arising, within [***] days of the Borrower acquiring rights therein.

(j) Use of Proceeds. Borrower shall use the proceeds of the Loans solely as working capital and to fund its general business requirements in accordance with the most recent Borrower Forecast and Budget and the provisions of this Agreement. Without limiting the foregoing, the proceeds of the Loans shall not be used to repay any portion of the amounts outstanding under the Outstanding Loans (as defined in Schedule 8(l)).

(k) Further Assurances and Additional Acts. From time to time, at its sole expense, Borrower will promptly execute and deliver and will cause to be executed and delivered all further instruments and documents, and will take all further action, that may be reasonably necessary or desirable, or that Lender may reasonably request, in order to perfect and protect any security interest granted or purported to be granted hereby or to enable Lender to exercise and enforce its rights and remedies hereunder with respect to any Collateral. Without limiting the generality of the foregoing, Borrower will: (i) (A) execute and file, record or register such financing or continuation statements, or amendments thereto, (B) execute and deliver, and cause to be executed and delivered, agreements establishing that Lender has “control” within the meaning of Article 9 of the UCC of specified items of Collateral to the extent required hereunder, (C) ) execute and deliver such Intellectual Property Security Agreements as are reasonably requested by Lender within five (5) Business Days of any such request, (D) promptly, upon a Responsible Officer obtaining knowledge thereof, deliver to Lender notice of any Commercial Tort Claim for damages greater than [***] it may bring against any person or entity, including the name and address of such person or entity, a detailed description of the facts, an estimate of Borrower’s damages thereunder, copies of any complaint or demand letter submitted by Borrower, and such other information as Lender may request, and, upon request by Lender, deliver any and all documentation required by Lender to perfect its security interest in all rights of Borrower in, to and under such Commercial Tort Claim and (E) deliver such other instruments or notices, in each case, as may be necessary and as Lender may reasonably request in order to perfect and preserve the security interests granted or purported to be granted hereby, (ii) furnish to Lender from time to time statements and schedules further identifying and describing the Collateral and such other reports in connection with the Collateral as Lender may reasonably request, all in reasonable detail, (iii) at Lender’s request, appear in and defend any action or proceeding that may affect the title of Borrower to or Lender’s security interest in all or any material part of the Collateral, and (iv) use commercially reasonable efforts to obtain any necessary consents of third parties to the perfection of a security interest to Lender with respect to any Collateral or the exercise of any right hereunder. Borrower hereby authorizes Lender to file one or more financing or continuation statements, and amendments thereto, relative to all or any part of the Collateral without the further consent of Borrower. In addition to and notwithstanding the foregoing, Borrower hereby irrevocably constitutes and appoints Lender, with full power of

substitution, as its true and lawful attorney-in-fact, with full irrevocable power and authority in its place and stead and in its name or otherwise, from time to time in Lender’s sole discretion, at Borrower’s sole cost and expense, to take any and all appropriate action and to execute and deliver any and all documents and instruments which Lender may deem reasonably necessary to accomplish the purposes of creating, perfecting, continuing and preserving an indefeasible continuing security interest in any and all of the Collateral in favor of Lender.

11. Negative Covenants. So long as any of the Obligations shall remain unpaid or outstanding, Borrower agrees that:

(a) Indebtedness. Borrower will not create, incur, assume or otherwise become liable for or suffer to exist any Indebtedness, whether secured or unsecured, other than:

(i) Indebtedness of Borrower to Lender hereunder;

(ii) accounts payable to trade creditors for goods and services and current operating liabilities (not the result of the borrowing of money) incurred in the ordinary course of Borrower’s business in accordance with customary terms and paid within the specified time, unless contested in good faith by appropriate proceedings and reserved for in accordance with GAAP;

(iii) Indebtedness directly related to the acquisition by Borrower of a product or product line; provided that such Indebtedness is owed to the seller of such product or product line or to a Person financing the acquisition of the same, but only to the extent the portion of the purchase price for the assets thus acquired is financed by Indebtedness; and if such Indebtedness is secured, then such Indebtedness shall be secured solely by the assets for which the acquisition financing was provided;

(iv) Indebtedness consisting of a refinancing of the Indebtedness permitted in subsection (iii) above; provided that the principal amount of such Indebtedness that is being refinanced does not increase;

(v) Indebtedness for capital leases as determined in accordance with GAAP not to exceed that amount allocated for capital leases in the annual budget of Borrower, which shall have been approved by the Board of Directors of Borrower;

(vi) Indebtedness arising from (i) the honoring by a bank or other financial institution of a check, draft or similar instrument against insufficient funds in the ordinary course of business; provided, however, that such Indebtedness is extinguished within ten (10) Business Days of its occurrence; (ii) bankers acceptances, performance, surety, judgment, appeal or similar bonds, instruments or obligations; and (iii) any customary cash management arrangements;

(vii) Indebtedness in respect of endorsements made in connection with the deposit of items for credit or collection in the ordinary course of business;

(viii) Indebtedness represented by property, liability and workers’ compensation insurance (which may be in the form of letters of credit); and

(b) Change in Nature of Business. Borrower will not engage in any material line of business substantially different from the biopharmaceutical business.

(i) consummate any acquisition of any Person by means of merger or other form of corporate reorganization in which outstanding shares of such Person are exchanged for securities or other consideration issued, or caused to be issued, by Borrower, or consummate a purchase of substantially all of any Person’s assets unless (A) Borrower is the surviving entity, and (B) both immediately before and after such merger, reorganization or acquisition, no Event of Default shall have occurred or be caused by virtue thereof; or

(ii) sell, transfer, lease or otherwise dispose of (whether in one transaction or in a series of transactions) all or substantially all of its assets without the consent of Lender, such consent not to be unreasonably withheld, conditioned or delayed.

(d) Change of Name, Etc. The Borrower shall not change its name, identity, corporate structure (e.g., by merger, consolidation, change in corporate form or otherwise), sole place of business, chief executive office, type of organization or jurisdiction of organization or establish any trade names unless it shall have (a) notified the Lender in writing at least ten (10) days prior to any such change or establishment, identifying such new proposed name, identity, corporate structure, sole place of business, chief executive office, jurisdiction of organization or trade name and providing such other information in connection therewith as the Lender may reasonably request and (b) taken all actions reasonably necessary or advisable to maintain the continuous validity, perfection and the same priority of the Lender’s security interest in the Collateral intended to be granted and agreed to hereby.

(e) Sales of Collateral. Other than Permitted Liens and Permitted Transfers, the Borrower will not transfer, pledge, hypothecate, encumber, license, sell or otherwise dispose of any of the Collateral without the prior written consent of the Lender, such consent not to be unreasonably withheld, conditioned or delayed.

(f) Distributions. Borrower will not declare or pay any dividends in respect of its capital stock, or purchase, redeem, retire or otherwise acquire for value any of its capital stock now or hereafter outstanding, return any capital to its stockholders as such, or make any loan of assets to its stockholders as such, except that Borrower may, so long as (i) no Event of Default has occurred and is continuing and (ii) the amount paid by Borrower does not exceed [***] in cash or value per year, repurchase shares of its capital stock from any of Borrower’s employees, directors or consultants upon the termination of service of such Person or repurchase shares of its capital stock in connection with Borrower’s stock option or other compensation plans.

(g) Transactions with Related Parties. Borrower will not (absent Lender’s prior written consent) enter into any transaction, including the purchase, sale or exchange of property or the rendering of any services, with any Affiliate, any officer or director thereof or any Person that beneficially owns or holds 5% or more of the equity securities, or 5% or more of the equity interest, thereof (a “Related Party”), except for an employment or consulting contract and equity award and similar agreements with Borrower and except for a transaction or contract that is in the ordinary course of business and that is upon fair and reasonable terms not less favorable to Borrower than it would obtain in a comparable arm’s length transaction with a Person not a Related Party; provided, however, that nothing in this subsection shall prohibit any transactions between Borrower and Lender.

12. Representations and Warranties of Lender. Lender represents and warrants to Borrower that:

(a) Purchase Entirely for Own Account. The Secured Promissory Note and the Borrower Equity Securities are being acquired for investment for Lender’s own account, not as a nominee or agent, and not with a view to the resale or distribution of any part thereof, and Lender has no present intention of selling, granting any participation in or otherwise distributing the same. Lender does not have any contract, undertaking, agreement or arrangement with any person to sell, transfer or grant participations to such person or to any third person, with respect to the Secured Promissory Note or Borrower Equity Securities.

(b) No Solicitation. At no time was Lender presented with or solicited by any publicly issued or circulated newspaper, mail, radio, television or other form of general advertising or solicitation in connection with the offer, sale and purchase of the Secured Promissory Note or Borrower Equity Securities.

(c) Disclosure of Information. Lender has received or has had full access to all of the information Lender considers necessary or appropriate to make an informed investment decision with respect to the Secured Promissory Note and Borrower Equity Securities. Lender has had an opportunity to ask questions and receive answers from Borrower, or is otherwise knowledgeable, regarding the terms and conditions of the offering of the Secured Promissory Note and Borrower Equity Securities and the business, properties, prospects and financial condition of Borrower.

(d) Investment Experience. Lender understands that the purchase of the Secured Promissory Note and Borrower Equity Securities involves substantial risk. Lender has experience investing in securities of companies in the development stage and acknowledges that it is able to fend for itself, can bear the economic risk of its investment and has such knowledge and experience in financial or business matters such that it is capable of evaluating the merits and risks of the investment in the Secured Promissory Note and Borrower Equity Securities and/or has a preexisting personal or business relationship with Borrower and certain of its officers, directors or controlling persons of a nature and duration that enables Lender to be aware of the character, business acumen and financial circumstances of such persons.

(e) Accredited Investor. Lender is familiar with the definition of, and qualifies as, an “accredited investor” within the meaning of Rule 501, as in effect as of the Effective Date, of Regulation D promulgated under the Securities Act.

(f) Restricted Securities. Lender understands that the Secured Promissory Note and Borrower Equity Securities are characterized as “restricted securities” under federal securities laws inasmuch as they are being acquired from Borrower in a transaction not involving a public offering and that, under such laws and applicable regulations, the Secured Promissory Note and Borrower Equity Securities may be resold without registration under the Securities Act only in certain limited circumstances. Lender represents that it is familiar with Rule 144 promulgated under the Securities Act, and understands the resale limitations imposed thereby and by the Securities Act. Lender understands and acknowledges that an investment in the Secured Promissory Note and Borrower Equity Securities involves an extremely high degree of risk and may result in a complete loss of Lender’s investment. Lender understands that the Secured Promissory Note and Borrower Equity Securities have not been and will not be registered under the Securities Act and have not been and will not be registered or qualified in any state in which they are offered and that Lender will not be able to resell or otherwise transfer the Secured Promissory Note and Borrower Equity Securities unless the Secured Promissory Note or Borrower Equity Securities are registered under the Securities Act and registered or qualified under applicable state securities laws, or an exemption from such registration or qualification is available.

(g) No Public Market. Lender understands and acknowledges that, whether or not the Secured Promissory Note and Borrower Equity Securities may be resold in the future without registration under the Securities Act, no public market exists for the Secured Promissory Note or Borrower Equity Securities and that it is uncertain whether a public market will ever exist for such securities.

(h) No Liquidity. Lender has no immediate need for liquidity in connection with its investment in the Secured Promissory Note and Borrower Equity Securities, does not anticipate being required to sell the Secured Promissory Note or Borrower Equity Securities in the foreseeable future and has the capacity to sustain a complete loss of its investment in the Secured Promissory Note and Borrower Equity Securities.

(i) Legends. Lender understands and agrees that the Secured Promissory Note and the certificates evidencing Borrower Equity Securities will bear legends substantially similar to those set forth below in addition to any other legend that may be required by applicable law, Borrower’s Certificate of Incorporation or Bylaws, Section 13 or any other agreement between Borrower and Lender:

(i) THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR REGISTERED OR QUALIFIED UNDER ANY APPLICABLE STATE SECURITIES LAWS, AND MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF (A) AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND REGISTRATION OR QUALIFICATION UNDER ANY APPLICABLE STATE

SECURITIES LAWS OR (B) AN OPINION OF COUNSEL IN FORM AND SUBSTANCE SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION AND QUALIFICATION ARE NOT REQUIRED PURSUANT TO AN EXEMPTION UNDER SUCH ACT AND SECURITIES LAWS; and

(ii) Any legend required by the laws of the State of California, including any legend required by the California Department of Corporations or any other state securities laws.

13. Lock-Up Period. Lender hereby agrees that it shall not, to the extent requested by Borrower or an underwriter of securities of Borrower, sell or otherwise transfer or dispose of the Secured Promissory Note, Borrower Equity Securities or other securities of Borrower then or thereafter owned by Lender for up to 180 days following the date of the final prospectus filed with the Securities and Exchange Commission relating to an effective registration statement of Borrower filed under the Securities Act (the “Lock-Up Period”). For purposes of this Section 13, the term “Borrower” shall include any wholly-owned subsidiary of Borrower into which Borrower merges or consolidates. In order to enforce the foregoing covenant, Borrower shall have the right to place the restrictive legend below on the Secured Promissory Note and the certificates representing Borrower Equity Securities subject to this Section 13 and to impose stop-transfer instructions with respect to the Secured Promissory Note, Borrower Equity Securities and such other Borrower securities of the Lender (and the shares or securities of every other person subject to the foregoing restriction) until the end of such Lock-Up Period. Lender further agrees to enter into any agreement reasonably required by any underwriter to implement the foregoing provisions within any reasonable timeframe so requested.

THE SECURITIES REPRESENTED HEREBY ARE SUBJECT TO A LOCK-UP RESTRICTION AS SET FORTH IN A CERTAIN AGREEMENT BETWEEN THE ISSUER AND THE ORIGINAL HOLDER OF THESE SECURITIES, A COPY OF WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE ISSUER. AS A RESULT OF SUCH AGREEMENT, THESE SECURITIES MAY NOT BE TRADED PRIOR TO 180 DAYS AFTER THE EFFECTIVE DATE OF THE INITIAL PUBLIC OFFERING OF THE COMMON STOCK OF THE ISSUER HEREOF. SUCH RESTRICTION IS BINDING ON TRANSFEREES OF THESE SECURITIES.

14. Event of Default. Any one of the following shall constitute an event of default (an “Event of Default”) under this Agreement:

(a) The Borrower fails to make any principal payment under the Secured Promissory Note or fails to pay any interest accruing on the Loans evidenced by the Secured Promissory Note and such failure continues for [***] Business Days after the date on which such payment should have been made;

(b) The Borrower fails to issue certificates representing the Borrower Equity Securities, as applicable;

(d) (i) any representation and warranty of the Borrower set forth in this Agreement, the Option Agreement or the Master License Agreement shall prove to be incorrect in any material respect or (ii) the Borrower breaches any covenant or agreement in this Agreement, the Option Agreement, the Master License Agreement, the Voting Agreement or that certain side letter agreement dated as of the date hereof with respect to Board Composition and Management Rights and such failure continues for [***] days after the date on which notice thereof shall have been given to the Borrower by the Lender;

(e) The Borrower fails to pay when due any Indebtedness of the Borrower in an aggregate amount of [***] or greater [***];

(f) A final judgment or judgments for the payment of money aggregating in excess of [***] (excluding any amounts covered by insurance) are rendered against the Borrower and which judgments are not, within [***] after the entry thereof, bonded, discharged or stayed pending appeal, or are not discharged within [***] days after the expiration of such stay;

(g) The Borrower shall (i) be dissolved, (ii) fail to remain Solvent, (iii) make an assignment for the benefit of creditors or make or send a notice of intended bulk transfer, (iv) file or commence any petition or proceeding for any relief under any bankruptcy, reorganization, arrangement, insolvency, readjustment of debt, receivership, liquidation or dissolution law or statute now or hereinafter in effect (whether at law or in equity); or

(h) Any trustee or receiver is appointed for the Borrower or any property of the Borrower, a meeting of creditors is convened or a committee of creditors is appointed for, or any petition or proceeding for any relief under any bankruptcy, reorganization, arrangement, insolvency, readjustment of debt, receivership, liquidation or dissolution law or statute now or hereinafter in effect (whether at law or in equity) is filed or commenced against the Borrower, which proceeding is not dismissed within [***].

15. Duty To Hold In Trust. Upon the occurrence and during the continuance of any Event of Default, following written notice from Lender the Borrower shall, upon receipt by it of any revenue, income or other sums subject to the Security Interest, whether payable pursuant to the Loan or otherwise, or of any check, draft, note, trade acceptance or other instrument evidencing an obligation to pay any such sum, hold the same in trust for the Lender and shall forthwith endorse and transfer any such sums or instruments, or both, to the Lender for application to the satisfaction of the Obligations.

16. Rights and Remedies Upon Default. Upon occurrence and during the continuance of any Event of Default, the Lender may, without notice or demand, do any or all of the following: (i) deliver notice of the Event of Default to Borrower, (ii) by notice to Borrower declare all Obligations immediately due and payable (but if an Event of Default described in Sections 14(g) or (h) occurs all Obligations shall be immediately due and payable without any action by the Lender) or (iii) by notice to Borrower suspend or terminate the obligations, if any, of the Lender to extend

credit for Borrower’s benefit under this Agreement or under any other agreement between Borrower and Lender or its Affiliates (but if an Event of Default described in Sections 14(g) or (h) occurs all obligations, if any, of the Lender to extend credit for Borrower’s benefit under this Agreement shall be immediately terminated without any action by the Lender). Without limitation, the Lender shall have the following rights and powers:

(a) The Lender shall have the right to take possession of the Collateral and, for that purpose, enter, with the aid and assistance of any person, any premises where the Collateral, or any part thereof, is or may be placed and remove the same, and the Borrower shall assemble the Collateral and make it reasonably available to the Lender at places which the Lender shall reasonably select, whether at the Borrower’s premises or elsewhere, and make reasonably available to the Lender, without rent, all of the Borrower’s respective premises and facilities for the purpose of the Lender taking possession of, removing or putting the Collateral in saleable or disposable form.

(b) The Lender shall have the right to operate the business of the Borrower using the Collateral and shall have the right to assign, sell, lease or otherwise dispose of and deliver all or any part of the Collateral, at public or private sale or otherwise, either with or without special conditions or stipulations, for cash or on credit or for future delivery, in such parcel or parcels and at such time or times and at such place or places, and upon such terms and conditions as the Lender may deem commercially reasonable, all without (except as shall be required by applicable statute and cannot be waived) advertisement or demand upon or notice to the Borrower or right of redemption of the Borrower, which are hereby expressly waived. Upon each such sale, lease, assignment or other transfer of Collateral, the Lender may, unless prohibited by applicable law which cannot be waived, purchase all or any part of the Collateral being sold, free from and discharged of all trusts, claims, right of redemption and equities of the Borrower, which are hereby waived and released.

(c) The Lender shall have the right to apply to the Obligations any amount held or controlled by the Lender owing to or for the credit or the account of Borrower, including, without limitation pursuant to the Master License Agreement.

17. Applications of Proceeds from Disposition of Collateral. The proceeds of any such sale, lease or other disposition of the Collateral hereunder shall be applied first, to the expenses of retaking, holding, storing, processing and preparing for sale, selling, and the like (including, without limitation, any taxes, fees and other costs incurred in connection therewith) of the Collateral, to the reasonable attorneys’ fees and expenses incurred by the Lender in enforcing its rights hereunder and in connection with collecting, storing and disposing of the Collateral, and then to satisfaction of the Obligations, and to the payment of any other amounts required by applicable law, after which the Lender shall pay to the Borrower any surplus proceeds.

18. Costs and Expenses. The Borrower agrees to pay all reasonable out-of-pocket fees, costs and expenses incurred in connection with any filing required hereunder, including without limitation, any financing statements, continuation statements, partial releases and/or termination statements related thereto. The Borrower will also, upon demand, pay to the Lender the amount of any and all reasonable expenses, including the reasonable fees and expenses of its counsel, which

the Lender may incur in connection with (i) the enforcement of this Agreement or (ii) the custody or preservation of, or the sale of, collection from, or other realization upon, any of the Collateral.

19. Security Interest Absolute. All rights of the Lender and all Obligations of the Borrower hereunder, shall be absolute and unconditional, irrespective of: (a) any lack of validity or enforceability of any Loan Document, or any portion hereof or thereof; (b) any change in the time, manner or place of payment or performance of, or in any other term of, all or any of the Obligations, or any other amendment or waiver of or any consent to any departure from the Secured Promissory Note or any other Loan Document; (c) any exchange, release or nonperfection of any of the Collateral, or any release or amendment or waiver of or consent to departure from any other collateral for, or any guaranty, or any other security, for all or any of the Obligations; (d) any action by the Lender to obtain, adjust, settle and cancel in its sole discretion any insurance claims or matters made or arising in connection with the Collateral; or (e) any other circumstance which might otherwise constitute any legal or equitable defense available to the Borrower, or a discharge of all or any part of the Security Interest granted hereby. The Borrower expressly waives presentment, protest, notice of protest, demand, notice of nonpayment and demand for performance. In the event that at any time any transfer of any Collateral or any payment received by the Lender hereunder shall be deemed by final order of a court of competent jurisdiction to have been a voidable preference or fraudulent conveyance under the bankruptcy or insolvency laws of the United States, or shall be deemed to be otherwise due to any party other than the Lender, then, in any such event, the Borrower’s obligations hereunder shall survive cancellation of this Agreement, and shall not be discharged or satisfied by any prior payment thereof and/or cancellation of this Agreement, but shall remain a valid and binding obligation enforceable in accordance with the terms and provisions hereof. The Borrower waives all right to require the Lender to proceed against any other person or to apply any Collateral which the Lender may hold at any time, or to marshal assets, or to pursue any other remedy. The Borrower waives any defense arising by reason of the application of the statute of limitations to any obligation secured hereby.

20. Power of Attorney. The Borrower hereby irrevocably appoints the Lender (such appointment being coupled with an interest) as the Borrower’s attorney-in-fact, with full authority in the place and stead of the Borrower and in the name of the Borrower, the Lender or otherwise, from time to time upon the occurrence and during the continuance of any Event of Default in the Lender’s discretion to take any action and to execute any instrument that the Lender may deem reasonably necessary or advisable to accomplish the purposes of this Agreement.

21. Term of Agreement. This Agreement and the Security Interest shall terminate on the date on which all payments under the Loan have been made in full, including as a result of such Loans converting into Borrower Securities. Upon such termination, the Lender will promptly file, at Lender’s sole cost and expense, all termination statements with respect to any financing or similar statement executed and filed pursuant to this Agreement.

22. Notices. All notices, consents, requests, approvals, demands, or other communication by any party to this Agreement or any other Loan Document must be in writing and shall be deemed to have been validly served, given, or delivered: (a) upon the earlier of actual receipt and three (3) Business Days after deposit in the U.S. mail, first class, registered or certified

mail return receipt requested, with proper postage prepaid; (b) one (1) Business Day after deposit with a reputable overnight courier with all charges prepaid; or (c) when delivered, if hand delivered by messenger, or (d) upon acknowledgment of receipt by email, all of which shall be addressed to the party to be notified and sent to the address, facsimile number, or email address indicated below.

23. Usury. In the event any interest is paid on the Secured Promissory Note which is deemed to be in excess of the then legal maximum rate, then that portion of the interest payment representing an amount in excess of the then legal maximum rate shall be deemed a payment of principal and applied against the principal of such Secured Promissory Note, or, if it exceeds such unpaid principal, refunded to Borrower. In determining whether the interest contracted for, charged, or received by Lender exceeds the maximum rate permitted by law, Lender may, to the extent permitted by applicable law, (a) characterize any payment that is not principal as an expense, fee, or premium rather than interest, (b) exclude voluntary prepayments and the effects thereof, and (c) amortize, prorate, allocate, and spread in equal or unequal parts the total amount of interest throughout the contemplated term of the Secured Promissory Note.

24. California Securities Law. THE SALE OF THE SECURITIES THAT ARE THE SUBJECT OF THIS AGREEMENT HAS NOT BEEN QUALIFIED WITH THE COMMISSIONER OF CORPORATIONS OF THE STATE OF CALIFORNIA AND THE ISSUANCE OF SUCH SECURITIES OR THE PAYMENT OR RECEIPT OF ANY PART

OF THE CONSIDERATION THEREFOR PRIOR TO SUCH QUALIFICATION IS UNLAWFUL, UNLESS THE SALE OF SECURITIES IS EXEMPT FROM QUALIFICATION BY SECTION 25100, 25102 OR 25105 OF THE CALIFORNIA CORPORATIONS CODE. THE RIGHTS OF ALL PARTIES TO THIS AGREEMENT ARE EXPRESSLY CONDITIONED UPON SUCH QUALIFICATION BEING OBTAINED, UNLESS THE SALE IS SO EXEMPT.

25. Miscellaneous.

(a) No course of dealing between the Borrower and the Lender, nor any failure to exercise, nor any delay in exercising, on the part of the Lender, any right, power or privilege hereunder or under the Loan shall operate as a waiver thereof; nor shall any single or partial exercise of any right, power or privilege hereunder or thereunder preclude any other or further exercise thereof or the exercise of any other right, power or privilege.

(b) All of the rights and remedies of the Lender with respect to the Collateral, whether established hereby or by the Loan or by any other agreements, instruments or documents or by law shall be cumulative and may be exercised singly or concurrently.

(c) This Agreement, together with the other Loan Documents, constitutes the entire agreement of the parties with respect to the subject matter hereof and is intended to supersede all prior negotiations, understandings and agreements with respect thereto. Except as specifically set forth in this Agreement, no provision of this Agreement may be modified or amended except by a written agreement specifically referring to this Agreement and signed by the parties hereto.

(d) In the event that any provision of this Agreement is held to be invalid, prohibited or unenforceable in any jurisdiction for any reason, unless such provision is narrowed by judicial construction, this Agreement shall, as to such jurisdiction, be construed as if such invalid, prohibited or unenforceable provision had been more narrowly drawn so as not to be invalid, prohibited or unenforceable. If, notwithstanding the foregoing, any provision of this Agreement is held to be invalid, prohibited or unenforceable in any jurisdiction, such provision, as to such jurisdiction, shall be ineffective to the extent of such invalidity, prohibition or unenforceability without invalidating the remaining portion of such provision or the other provisions of this Agreement and without affecting the validity or enforceability of such provision or the other provisions of this Agreement in any other jurisdiction.

(e) No waiver of any breach or default or any right under this Agreement shall be considered valid unless in writing and signed by the party giving such waiver, and no such waiver shall be deemed a waiver of any subsequent breach or default or right, whether of the same or similar nature or otherwise.

(f) This Agreement shall be binding upon and inure to the benefit of each party hereto and its successors and permitted assigns. Neither this Agreement nor the Secured Promissory Note may be assigned by either party without the prior written consent of the other party, except that: (i) Borrower may assign this Agreement along with the Secured Promissory Note to one or more of its Affiliates, without Lender’s prior consent, and (ii) Lender may assign this Agreement

or the Secured Promissory Note to one or more of its Affiliates, or pursuant to a change in control of Lender, without Borrower’s prior consent.

(g) California law governs the Loan Documents, without regard to principles of conflicts of law, except to the extent the validity, perfection or enforcement of a security interest hereunder in respect of any particular Collateral which are pursuant to mandatory choice of law rules governed by a jurisdiction other than the State of California in which case such law shall govern. Borrower hereby waives personal service of the summons, complaints, and other process issued in such action or suit and agrees that service of such summons, complaints, and other process may be made by registered or certified mail addressed to Borrower at the address set forth in, or subsequently provided by Borrower in accordance with, this Agreement and that service so made shall be deemed completed upon the earlier to occur of Borrower’s actual receipt thereof or three (3) days after deposit in the U.S. mails, proper postage prepaid.

(h) This Agreement may be executed in any number of counterparts, each of which when so executed shall be deemed to be an original, and all of which taken together shall constitute one and the same Agreement. In the event that any signature is delivered by facsimile transmission, such signature shall create a valid binding obligation of the party executing (or on whose behalf such signature is executed) the same with the same force and effect as if such facsimile signature were the original thereof.

(i) To the fullest extent permitted by applicable law, the Borrower shall remain obligated hereunder notwithstanding that, any demand for payment of any of the Obligations made by Lender may be rescinded by Lender and any of the Obligations continued, and the Obligations or any collateral security or guarantee therefor or right of offset with respect thereto, may, from time to time, in whole or in part, be renewed, extended, amended, modified, accelerated, compromised, waived, surrendered or released by the Lender, and the Secured Promissory Note and any other documents executed and delivered in connection therewith may be amended, modified, supplemented or terminated, in whole or in part, as Lender may deem advisable from time to time, and any collateral security, guarantee or right of offset at any time held by Lender for the payment of the Obligations may be sold, exchanged, waived, surrendered or released.
