Ladies and Gentlemen:

The undersigned, Viking Therapeutics, Inc., a Delaware corporation (the “Company”), hereby confirms its agreement (this “Agreement”) to issue and sell to the underwriter or underwriters, as the case may be, named in Schedule I hereto (each, an “Underwriter” and, collectively, the “Underwriters”), for whom Maxim Group LLC is acting as representative (in such capacity, the “Representative”), an aggregate of shares (the “Firm Shares”) of the Company’s common stock, $0.00001 par value per share ( “Common Stock”) and warrants to purchase an aggregate of shares of Common Stock (the “Warrants,” and collectively with the Firm Shares, the “Firm Securities”). In addition, the Company proposes to grant to the Underwriters an option to purchase from the Company up to an additional shares of Common Stock (the “Option Shares”) and/or Warrants to purchase up to an additional shares of Common Stock (the “Option Warrants”) for the purpose of covering over-allotments in connection with the sale of the Firm Securities (collectively, the “Option Securities”). The Firm Securities, the Option Securities and the shares of Common Stock issuable upon the exercise of the Warrants (the “Warrant Shares”) are collectively referred to herein as the “Transaction Securities.” The offering and sale of the Transaction Securities contemplated by this Agreement is referred to herein as the “Offering.”

1. Transaction Securities; Over-Allotment Option.

(a) Purchase of the Firm Securities. On the basis of the representations and warranties herein contained, but subject to the terms and conditions herein set forth, the Company agrees to issue and sell, severally and not jointly, to the several Underwriters, an aggregate of the Firm Securities at a purchase price (net of discounts and commissions) per Firm Share and warrant to purchase shares of Common Stock of $ , which represents a 8.0% discount to the public offering price per Firm Share and warrant to purchase shares of Common Stock.

(b) The Underwriters, severally and not jointly, agree to purchase from the Company the number of Firm Shares set forth opposite their respective names on Schedule I attached hereto and made a part hereof.

(c) Payment and Delivery. Delivery and payment for the Firm Shares shall be made at 10:00 a.m., Eastern Time, on the third Business Day following the effective date (the “Effective Date”) of the Registration Statement (as hereinafter defined) (or the fourth Business Day following the Effective Date, if the Registration Statement is declared effective after 4:30 p.m. Eastern Time) or at such earlier time as shall be agreed upon by the Representative and the Company at the offices of the Representative or at such other place as shall be agreed upon by the Representative and the Company. The hour and date of delivery and payment for the Firm Securities is called the “Closing Date.” The closing of the payment of the purchase price for, and delivery of certificates representing, the Firm Securities is referred to herein as the “Closing.” Payment for the Firm Securities shall be made on the Closing Date by wire transfer in Federal (same day) funds upon delivery to the Representative of certificates (in form and substance satisfactory to the Underwriters) representing the Firm Securities (or through the full fast transfer facilities of the Depository Trust Company (the “DTC”)) for the account of the Underwriters. The Firm Securities shall be registered in such name or names and in such authorized denominations as the Representative may request in writing at least two Business Days prior to the Closing Date. The Company will permit the Representative to examine and package the Firm Securities for delivery, at least one full Business Day prior to the Closing Date. The Company shall not be obligated to sell or deliver the Firm Securities except upon tender of payment by the Representative for all the Firm Securities.

(d) Over-Allotment Option. For the purposes of covering any over-allotments in connection with the distribution and sale of the Firm Securities, the Representative on behalf of the Underwriters is hereby granted an option (the “Over-Allotment Option”) to purchase all or any part of the Option Shares at $ per share and/or Option Warrants at $ per warrant.

(e) Exercise of Option. The Over-Allotment Option granted pursuant to Section 1(d) may be exercised by the Representative as to all (at any time) or any part (from time to time) of the Option Shares and/or Option Warrants within 45 days after the Closing Date. The Underwriters will not be under any obligation to purchase any of such Option Shares and/or Option Warrants prior to the exercise of the Over-Allotment Option. The Over-Allotment Option granted hereby may be exercised by the giving of written notice to the Company from the Representative, setting forth the number of Option Shares and/or Option Warrants to be purchased and the date and time for delivery of and payment for such Option Shares and/or Option Warrants, which will not be later than five Business Days after the date of the notice or such other time as shall be agreed upon by the Company and the Representative, at the offices of the Representative or at such other place as shall be agreed upon by the Company and the Representative. If such delivery and payment for all of the Option Shares and/or Option Warrants does not occur on the Closing Date, the date and time of any closing for such Option Shares and/or Option Warrants will be as set forth in the notice (hereinafter the “Option Closing Date”). Upon exercise of the Over-Allotment Option, the Company will become obligated to convey to the Underwriters, and, subject to the terms and conditions set forth herein, the Underwriters will become obligated to purchase, the number of Option Shares and/or Option Warrants specified in such notice. If any Option Shares and/or Option Warrants are to be purchased, each Underwriter agrees, severally and not jointly, to purchase the number of Option Shares and/or Option Warrants (subject to such adjustments to eliminate fractional shares as the Representative may determine) set forth in the written notice to the Company from the Representative.

(f) Payment and Delivery of Option Shares and/or Option Warrants. Payment for Option Shares and/or Option Warrants shall be made on the Option Closing Date by wire transfer in Federal (same day) funds by deposit of the price for the Option Shares and/or Option Warrants being purchased to the Company upon delivery to the Underwriters of certificates (in form and substance satisfactory to the Underwriters) representing such Option Shares and/or Option Warrants (or through the full fast transfer facilities of DTC) for the account of the Underwriters. The certificates representing the Option Shares and/or Option Warrants to be delivered will be in such denominations and registered in such names as the Representative requests not less than two Business Days prior to the Closing Date or the Option Closing Date, as the case may be, and will be made available to the Representative for inspection, checking and packaging at the aforesaid office of the Company’s transfer agent or correspondent not less than one full Business Day prior to the Closing Date or the Option Closing Date, as the case may be.

2. Representations and Warranties of the Company. The Company represents, warrants and covenants to, and agrees with, each of the Underwriters that, as of the date hereof and as of the Closing Date:

(a) Compliance with Registration Requirements. The Company has prepared and filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-1 (Registration No. 333-208182), and amendments thereto, and related preliminary prospectuses for the registration under the Securities Act of 1933, as amended (the “Securities Act”), of the Transaction Securities which registration statement, as so amended (including post-effective amendments, if any), has been declared effective by the Commission and copies of which have heretofore been delivered to the Underwriters. The registration statement, as amended at the time it became effective, including the prospectus, financial statements, schedules, exhibits and other information (if any) deemed to be part of the registration statement at the time of effectiveness pursuant to Rule 430A under the Securities Act, is hereinafter referred to as the “Registration Statement.” If the Company has filed or is required pursuant to the terms hereof to file a registration statement pursuant to Rule 462(b) under the Securities Act registering additional Transaction Securities (a “Rule 462(b) Registration Statement”), then, unless otherwise specified, any reference herein to the term “Registration Statement” shall be deemed to include such Rule 462(b) Registration Statement. Other than a Rule 462(b) Registration Statement, which, if filed, becomes effective upon filing, no other document with respect to the Registration Statement has heretofore been filed with the Commission. All of the Transaction Securities have been registered under the Securities Act pursuant to the Registration Statement or, if any Rule 462(b) Registration Statement is filed, will be duly registered under the Securities Act with the filing of such Rule 462(b) Registration Statement. The Company has responded to all requests of the Commission for additional or supplemental information. Based on a review of the Commission’s website at xxxx://xxx.xxx.xxx/xxxxxxxxxx/xxxxxxxxxx.xxxxx, no stop order suspending the effectiveness of either the Registration Statement or the Rule 462(b) Registration Statement, if any, has been issued and no proceeding for that purpose has been initiated or, to the Company’s knowledge, threatened by the Commission. The Company, if required by the Securities Act and the rules and regulations of the Commission (the “Rules and Regulations”), proposes to file the Prospectus with the Commission pursuant to Rule 424(b) under the Securities Act (“Rule 424(b)”). The prospectus, in the form in which it is to be filed with the Commission pursuant to Rule 424(b), or, if the prospectus is not to be filed with the Commission pursuant to Rule 424(b), the prospectus in the form included as part of the

Registration Statement at the time the Registration Statement became effective, is hereinafter referred to as the “Prospectus,” except that if any revised prospectus or prospectus supplement shall be provided to the Underwriters by the Company for use in connection with the Offering which differs from the Prospectus (whether or not such revised prospectus or prospectus supplement is required to be filed by the Company pursuant to Rule 424(b)), the term “Prospectus” shall also refer to such revised prospectus or prospectus supplement, as the case may be, from and after the time it is first provided to the Underwriters for such use. Any preliminary prospectus or prospectus subject to completion included in the Registration Statement or filed with the Commission pursuant to Rule 424 under the Securities Act is hereafter called a “Preliminary Prospectus.” Any reference herein to the Registration Statement, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include the exhibits or documents incorporated by reference therein pursuant to the Rules and Regulations on or before the Effective Date of the Registration Statement, the date of such Preliminary Prospectus or the date of the Prospectus, as the case may be. Any reference herein to the terms “amend”, “amendment” or “supplement” with respect to the Registration Statement, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include: (i) the filing of any document under the Securities Exchange Act of 1934, as amended, and together with the Rules and Regulations promulgated thereunder (the “Exchange Act”), after the Effective Date, the date of such Preliminary Prospectus or the date of the Prospectus, as the case may be, which is incorporated therein by reference, and (ii) any such document so filed. All references in this Agreement to the Registration Statement, the Rule 462(b) Registration Statement, a Preliminary Prospectus and the Prospectus, or any amendments or supplements to any of the foregoing, shall be deemed to include any copy thereof filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval System (“XXXXX”). The Prospectus delivered to the Underwriters for use in connection with the Offering was or will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to XXXXX, except to the extent permitted by Regulation S-T promulgated by the Commission.

(b) Registration Statement and Prospectus. At the time of the effectiveness of the Registration Statement or any Rule 462(b) Registration Statement or the effectiveness of any post-effective amendment to the Registration Statement, when the Prospectus is first filed with the Commission pursuant to Rule 424(b), when any supplement to or amendment of the Prospectus is filed with the Commission, at all other subsequent times until the completion of the public offer and sale of the Firm Securities and Option Securities, if applicable, and at the Closing Date and any Option Closing Date, if applicable, the Registration Statement and the Prospectus and any amendments thereof and supplements or exhibits thereto complied or will comply in all material respects with the applicable provisions of the Securities Act, the Exchange Act and the Rules and Regulations, and did not and will not, as of the date of such amendment or supplement, contain an untrue statement of a material fact and did not and will not, as of the date of such amendment or supplement, omit to state any material fact required to be stated therein or necessary in order to make the statements therein: (i) in the case of the Registration Statement, not misleading, and (ii) in the case of the Prospectus, in light of the circumstances under which they were made as of its date, not misleading. When any Preliminary Prospectus was first filed with the Commission (whether filed as part of the Registration Statement for the registration of the Transaction Securities or any amendment thereto or pursuant to Rule 424(a) under the Securities Act) and when any amendment thereof or supplement thereto was first filed with the Commission, such Preliminary Prospectus and any amendments thereof and supplements thereto

complied in all material respects with the applicable provisions of the Securities Act, the Exchange Act and the Rules and Regulations and did not contain an untrue statement of a material fact and did not omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. No representation and warranty is made in this subsection (b), however, with respect to any information contained in or omitted from the Registration Statement or the Prospectus or any related Preliminary Prospectus or any amendment thereof or supplement thereto in reliance upon and in conformity with information furnished in writing to the Company by or on behalf of any Underwriter through the Representative specifically for use therein. The parties acknowledge and agree that such information provided by or on behalf of any Underwriter consists solely of the following information in the Prospectus: the statements concerning the Underwriters set forth in the “Underwriting” section of the Prospectus (the “Underwriters’ Information”).

(c) Free Writing Prospectuses. Neither: (i) any Issuer-Represented General Free Writing Prospectus(es) (as defined below) issued at or prior to the Applicable Time (as defined below) and the Statutory Prospectus (as defined below), all considered together (collectively, the “General Disclosure Package”), nor (ii) any individual Issuer-Represented Limited-Use Free Writing Prospectus(es) (as defined below), when considered together with the General Disclosure Package, includes or included as of the Applicable Time any untrue statement of a material fact or omits or omitted as of the Applicable Time to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The preceding sentence does not apply to statements in or omissions from any Statutory Prospectus included in the Registration Statement, the General Disclosure Package or any Issuer-Represented Limited-Use Free Writing Prospectus (as defined below) in conformity with the Underwriters’ Information.

(d) Emerging Growth Company. From the time of the initial filing of the Registration Statement with the Commission (or, if earlier, the first date on which the Company engaged directly or through any person authorized to act on its behalf in any Testing-the-Waters Communication (as defined below)) through the date hereof, the Company has been and is an “emerging growth company,” as defined in Section 2(a) of the Securities Act (an “Emerging Growth Company”). “Testing-the-Waters Communication” means any oral or written communication with potential investors undertaken in reliance on Section 5(d) of the Securities Act.

(e) Testing-the-Waters Materials. The Company (i) has not alone engaged in any Testing-the-Waters Communications, other than Testing-the-Waters Communications with the prior consent of the Representative with entities that are qualified institutional buyers within the meaning of Rule 144A under the Securities Act or institutions that are accredited investors within the meaning of Rule 501 under the Securities Act and (ii) has not authorized anyone other than the Representative to engage in Testing-the-Waters Communications. The Company reconfirms that the Representative has been authorized to act on its behalf in undertaking Testing-the-Waters Communications. The Company has not distributed any Written Testing-the-Waters Communications (as defined below) other than those listed on Schedule III hereto. “Written Testing-the-Waters Communication” means any Testing-the-Waters Communication that is a written communication within the meaning of Rule 405 under the

Securities Act. Any individual Written Testing-the-Waters Communication does not conflict with the information contained in the Registration Statement or the General Disclosure Package, and when taken together with the General Disclosure Package as of the Applicable Time, did not contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(f) Conflicts with Registration Statement or Prospectus. Each Issuer-Represented Free Writing Prospectus and Written Testing-the-Waters Communication, as of its respective issue date and at all subsequent times until the later of the Closing Date, the last Option Closing Date or until any earlier date that the Company notified or notifies the Representative as described in the next sentence, did not, does not and will not include any information that conflicted, conflicts or will conflict with the information contained in the then-current Registration Statement, Preliminary Prospectus, Statutory Prospectus or Prospectus. If at any time following issuance of an Issuer-Represented Free Writing Prospectus or Written Testing-the-Waters Communication there occurred or occurs an event or development as a result of which such Issuer-Represented Free Writing Prospectus or Written Testing-the-Waters Communication conflicted or would conflict with the information contained in the then-current Registration Statement, Preliminary Prospectus, Statutory Prospectus or Prospectus relating to the Transaction Securities or included or would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances prevailing at that subsequent time, not misleading, the Company has notified or will notify promptly the Representative so that any use of such Issuer-Represented Free Writing Prospectus or Written Testing-the-Waters Communication may cease until it is promptly amended or supplemented by the Company, at its own expense, to eliminate or correct such conflict, untrue statement or omission.

(g) Distribution of Materials. The Company has not distributed and will not distribute any prospectus or other offering material in connection with the offering and sale of the Transaction Securities other than the General Disclosure Package, any Issuer-Represented Limited-Use Free Writing Prospectus or the Prospectus or other materials permitted by the Securities Act to be distributed by the Company. Unless the Company obtains the prior consent of the Representative, the Company has not made and will not make any offer relating to the Transaction Securities that would constitute an “issuer free writing prospectus,” as defined in Rule 433 under the Securities Act, or that would otherwise constitute a “free writing prospectus,” as defined in Rule 405 under the Securities Act, required to be filed with the Commission; provided that the prior written consent of the Representative shall be deemed to have been given in respect of any free writing prospectus referenced on Schedule III attached hereto. The Company has complied and will comply with the requirements of Rules 164 and 433 under the Securities Act applicable to any Issuer-Represented Free Writing Prospectus as of its issue date and at all subsequent times through the Closing Date, including timely filing with the Commission where required, legending and record keeping. To the extent an electronic road show is used, the Company has satisfied and will satisfy the conditions in Rule 433 under the Securities Act to avoid a requirement to file with the Commission any electronic road show.

(h) Consent for Free Writing Prospectuses. Each Underwriter agrees that, unless it obtains the prior written consent of the Company, it will not make any offer relating to the

Transaction Securities that would constitute an Issuer-Represented Free Writing Prospectus or that would otherwise (without taking into account any approval, authorization, use or reference thereto by the Company) constitute a “free writing prospectus” required to be filed by the Company with the Commission or retained by the Company under Rule 433 of the Securities Act; provided that the prior written consent of the Company hereto shall be deemed to have been given in respect of any Issuer-Represented General Free Writing Prospectuses referenced on Schedule III attached hereto.

(i) Certain Definitions. As used in this Agreement, the terms set forth below shall have the following meanings:

(i) “Applicable Time” means , 2016, (Eastern Time) on the date of this Agreement.

(iii) “Issuer-Represented Free Writing Prospectus” means any “issuer free writing prospectus,” as defined in Rule 433 under the Securities Act, relating to the Transaction Securities that (A) is required to be filed with the Commission by the Company, or (B) is exempt from filing pursuant to Rule 433(d)(5)(i) under the Securities Act because it contains a description of the Transaction Securities or of the Offering that does not reflect the final terms or pursuant to Rule 433(d)(8)(ii) because it is a “bona fide electronic road show,” as defined in Rule 433 under the Securities Act, in each case in the form filed or required to be filed with the Commission or, if not required to be filed, in the form retained in the Company’s records pursuant to Rule 433(g) under the Securities Act.

(iv) “Issuer-Represented General Free Writing Prospectus” means any Issuer-Represented Free Writing Prospectus that is intended for general distribution to prospective investors, as evidenced by its being specified in Schedule III to this Agreement.

The term Issuer-Represented Limited-Use Free Writing Prospectus also includes any “bona fide electronic road show,” as defined in Rule 433 under the Securities Act, that is made available without restriction pursuant to Rule 433(d)(8)(ii), even though not required to be filed with the Commission.

Prior to 10:00 a.m., Eastern Time, on the Business Day next succeeding the date of this Agreement and from time to time thereafter, the Company will furnish the Representative with copies of the Prospectus in New York City in such quantities as the Underwriters may reasonably request.

(j) During the 90 day period following the Closing Date, the Company will not file any registration statement relating to the offer or sale of any of the Company’s securities, except a registration statement on Form S-8, or amendment thereafter filed with the Commission in connection with any current equity compensation plans, without the consent of the Representative.

The Company shall announce the impending release or waiver by press release through a major news service at least two (2) business days before the effective date of the release or waiver.

(b) Each Underwriter, severally and not jointly, shall indemnify and hold harmless the Company, each of the directors of the Company, each of the officers of the Company who shall have signed the Registration Statement, and each other person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, against any losses, liabilities, claims, damages and expenses whatsoever as incurred (including but not limited to reasonable attorneys’ fees and any and all expenses reasonably incurred in investigating, preparing or defending against any litigation, commenced or threatened, or any claim whatsoever, and any and all amounts paid in settlement of any claim or litigation), joint or several, to which they or any of them may become subject under the Securities Act, the Exchange Act or otherwise (including in settlement of any litigation if such

The parties agree that such information provided by or on behalf of any Underwriter through the Representative consists solely of the material referred to in the last sentence of Section 2(b).

(c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of any claims or the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify each party against whom indemnification is to be sought in writing of the claim or the commencement thereof (but the failure to so notify an indemnifying party shall not relieve the indemnifying party from any liability which it may have under this Section 7 to the extent that it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability that such indemnifying party may have otherwise than on account of the indemnity agreement hereunder). In case any such claim or action is brought against any indemnified party, and it notifies an indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate, at its own expense, in the defense of such action, and to the extent it may elect by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel satisfactory to such indemnified party; provided, however, that counsel to the indemnifying party shall not (except with the written consent of the indemnified party) also be counsel to the indemnified party. Notwithstanding the foregoing, the indemnified party or parties shall have the right to employ its or their own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of such indemnified party or parties unless (i) the employment of such counsel shall have been authorized in writing by one of the indemnifying parties in connection with the defense of such action, (ii) the indemnifying parties shall not have employed counsel to have charge of the defense of such action within a reasonable time after notice of commencement of the action, (iii) the indemnifying party does not diligently defend the action after assumption of the defense, or (iv) such indemnified party or parties shall have reasonably concluded that a conflict may arise between the positions of the indemnifying party and the indemnified party, or any of them, in conducting the defense of any such action or there may be legal defenses available to it or them which are different from or additional to those available to

one or all of the indemnifying parties (in which case the indemnifying parties shall not have the right to direct the defense of such action on behalf of the indemnified party or parties), in any of which events such fees and expenses shall be borne by the indemnifying parties and shall be paid as incurred. No indemnifying party shall, without the prior written consent of the indemnified parties, effect any settlement or compromise of, or consent to the entry of judgment with respect to, any pending or threatened claim, investigation, action or proceeding in respect of which indemnity or contribution may be or could have been sought by an indemnified party under this Section 7 or Section 8 (whether or not the indemnified party is an actual or potential party thereto), unless (x) such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such claim, investigation, action or proceeding and (ii) does not include a statement as to or an admission of fault, culpability or any failure to act, by or on behalf of the indemnified party, and (y) the indemnifying party confirms in writing its indemnification obligations hereunder with respect to such settlement, compromise or judgment.

8. Contribution. In order to provide for contribution in circumstances in which the indemnification provided for in Section 7 is for any reason held to be unavailable from any indemnifying party or is insufficient to hold harmless a party indemnified thereunder, the Company and the Underwriters shall contribute to the aggregate losses, claims, damages, liabilities and expenses of the nature contemplated by such indemnification provision (including any investigation, legal and other expenses incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claims asserted, but after deducting in the case of losses, claims, damages, liabilities and expenses suffered by the Company, any contribution received by the Company from persons, other than the Underwriters, who may also be liable for contribution, including persons who control the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, officers of the Company who signed the Registration Statement and directors of the Company) as incurred to which the Company and one or more of the Underwriters may be subject, in such proportions as is appropriate to reflect the relative benefits received by the Company and the Underwriters from the Offering or, if such allocation is not permitted by applicable law, in such proportions as are appropriate to reflect not only the relative benefits referred to above but also the relative fault of the Company and the Underwriters in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Underwriters shall be deemed to be in the same proportion as (x) the total proceeds from the Offering (net of underwriting discounts and commissions but before deducting expenses) received by the Company bears to (y) the underwriting discount or commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus. The relative fault of each of the Company and of the Underwriters shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 8 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 8. The aggregate amount of losses, liabilities, claims, damages

and expenses incurred by an indemnified party and referred to above in this Section 8 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any judicial, regulatory or other legal or governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission. Notwithstanding the provisions of this Section 8: (i) no Underwriter shall be required to contribute any amount in excess of the amount by which the discounts and commissions applicable to the Firm Shares and Option Shares underwritten by it and distributed to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission and (ii) no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8, each person, if any, who controls an Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as such Underwriter, and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, each officer of the Company who shall have signed the Registration Statement and each director of the Company shall have the same rights to contribution as the Company, subject in each case to clauses (i) and (ii) of the immediately preceding sentence. Any party entitled to contribution will, promptly after receipt of notice of commencement of any action, suit or proceeding against such party in respect of which a claim for contribution may be made against another party or parties, notify each party or parties from whom contribution may be sought, but the omission to so notify such party or parties shall not relieve the party or parties from whom contribution may be sought from any obligation it or they may have under this Section 8 or otherwise. The obligations of the Underwriters to contribute pursuant to this Section 8 are several in proportion to the respective number of Firm Securities to be purchased by each of the Underwriters hereunder and not joint.

9. Underwriter Default.

(a) If any Underwriter or Underwriters shall default in its or their obligation to purchase Firm Securities hereunder, and if the securities with respect to which such default relates (the “Default Securities”) do not (after giving effect to arrangements, if any, made by the Representative pursuant to subsection (b) below) exceed in the aggregate 10% of the number of Firm Securities, each non-defaulting Underwriter, acting severally and not jointly, agrees to purchase from the Company that number of Default Securities that bears the same proportion of the total number of Default Securities then being purchased as the number of Firm Securities set forth opposite the name of such Underwriter on Schedule I hereto bears to the aggregate number of Firm Securities set forth opposite the names of the non-defaulting Underwriters, subject, however, to such adjustments to eliminate fractional shares as the Representative in its sole discretion shall make.

(b) In the event that the aggregate number of Default Securities exceeds 10% of the number of Firm Securities, the Representative may in its discretion arrange for themselves or for another party or parties (including any non-defaulting Underwriter or Underwriters who so agree) to purchase the Default Securities on the terms contained herein. In the event that within 48 hours after such a default the Representative does not arrange for the purchase of the Default

Securities as provided in this Section 9, this Agreement shall thereupon terminate, without liability on the part of the Company with respect thereto (except in each case as provided in Sections 5, 7, 8, 9 and 11(d)) or the Underwriters, but nothing in this Agreement shall relieve a defaulting Underwriter or Underwriters of its or their liability, if any, to the other Underwriters and the Company for damages occasioned by its or their default hereunder.

(c) In the event that any Default Securities are to be purchased by the non-defaulting Underwriters, or are to be purchased by another party or parties as aforesaid, the Representative or the Company shall have the right to postpone the Closing Date for a period, not exceeding five (5) Business Days, in order to effect whatever changes may thereby be necessary in the Registration Statement or the Prospectus or in any other documents and arrangements, and the Company agrees to file promptly any amendment or supplement to the Registration Statement or the Prospectus which, in the reasonable opinion of Underwriters’ Counsel, may thereby be made necessary or advisable. The term “Underwriter” as used in this Agreement shall include any party substituted under this Section 9 with like effect as if it had originally been a party to this Agreement with respect to such Firm Securities.

10. Survival of Representations and Agreements. All representations and warranties, covenants and agreements of the Company and the Underwriters contained in this Agreement or in certificates of officers of the Company submitted pursuant hereto, including the agreements contained in Section 5, this Section 10 and Sections 14 and 15, the indemnity agreements contained in Section 7 and the contribution agreements contained in Section 8, shall remain operative and in full force and effect regardless of any investigation made by or on behalf of any Underwriter or any controlling person thereof or by or on behalf of the Company, any of its officers and directors or any controlling person thereof, and shall survive delivery of and payment for the Firm Securities and the Option Securities to and by the Underwriters. The representations, covenants and agreements contained in Sections 5, 7, 8, this Section 10 and Sections 12, 13, 14 and 15 shall survive any termination of this Agreement, including termination pursuant to Section 9 or 11. The representations, covenants and obligations contained in Sections 2, 3 and 4 shall survive termination of this Agreement if any Securities are purchased pursuant to this Agreement.

11. Effective Date of Agreement; Termination.

(a) This Agreement shall become effective upon the later of: (i) receipt by the Representative and the Company of notification of the effectiveness of the Registration Statement or (ii) the execution of this Agreement. Notwithstanding any termination of this Agreement, the provisions of this Section 11 and of Sections 5, 7, 8, 10, 12, 13, 14 and 15, inclusive, shall remain in full force and effect at all times after the execution hereof. If this Agreement is terminated after any Firm Securities or Option Securities have been purchased hereunder, the provisions of Sections 2, 3 and 4 shall survive termination of this Agreement.

(b) The Representative shall have the right to terminate this Agreement at any time prior to the consummation of the Closing if: (i) any domestic or international event or act or occurrence has materially disrupted, or in the opinion of the Representative will in the immediate future materially disrupt, the market for the Company’s securities or securities in general; (ii) trading on the New York Stock Exchange, Inc. or The NASDAQ Stock Market LLC shall have

been suspended or been made subject to material limitations, or minimum or maximum prices for trading shall have been fixed, or maximum ranges for prices for securities shall have been required, on the New York Stock Exchange, Inc. or The NASDAQ Stock Market LLC or by order of the Commission, FINRA or any other governmental authority having jurisdiction; (iii) a banking moratorium has been declared by any state or federal authority or if any material disruption in commercial banking or securities settlement or clearance services shall have occurred; or (iv) (A) there shall have occurred any outbreak or escalation of hostilities or acts of terrorism involving the United States or there is a declaration of a national emergency or war by the United States or (B) there shall have been any other calamity or crisis or any change in political, financial or economic conditions if the effect of any such event in (A) or (B), in the judgment of the Representative, is so material and adverse that such event makes it impracticable or inadvisable to proceed with the offering, sale and delivery of the Firm Securities on the terms and in the manner contemplated by the Prospectus.

(d) If this Agreement shall be terminated pursuant to any of the provisions hereof or if the sale of the Firm Securities or the Option Securities provided for herein is not consummated because any condition to the obligations of the Underwriters set forth herein is not satisfied or because of any refusal, inability or failure on the part of the Company to perform any agreement herein or comply with any provision hereof, the Company will, subject to demand by the Representative, reimburse the Underwriters for those out-of-pocket expenses (including the actual, reasonable and documented fees and expenses of Underwriters’ Counsel), actually and reasonably incurred by the Underwriters in connection herewith in an aggregate amount not to exceed $75,000, less the Advance previously paid.

As Representative of the Underwriters

named on Schedule I hereto

Ladies and Gentlemen:

The undersigned, a holder of common stock, par value $0.00001 per share (“Common Stock”), or rights to acquire Common Stock, of Viking Therapeutics, Inc., a Delaware corporation (the “Company”) understands that you, as representative (the “Representative”) of the several Underwriters, propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) with the Company, providing for the public offering of Common Stock and warrants to purchase shares of Common Stock (the “Securities”) pursuant to registration statement number 333-208182 (the “Public Offering”) by the several Underwriters named on Schedule I to the Underwriting Agreement (the “Underwriters”). Capitalized terms used herein and not otherwise defined shall have the meanings set forth in the Underwriting Agreement.

In consideration of the Underwriters’ agreement to enter into the Underwriting Agreement and to proceed with the Public Offering of the Securities, and for other good and valuable consideration receipt of which is hereby acknowledged, the undersigned hereby agrees for the benefit of the Company, the Representative and the other Underwriters that, without the prior written consent of the Representative, the undersigned will not, during the period ending 90 days (the “Lock-Up Period”) after the date of the final prospectus supplement relating to the Public Offering (the “Effective Date”), directly or indirectly, unless otherwise provided herein, (a) offer, sell, agree to offer or sell, solicit offers to purchase, grant any call option or purchase any put option with respect to, pledge, borrow or otherwise dispose (each a “Transfer”) of any Relevant Security (as defined below), or (b) establish or increase any “put equivalent position” or liquidate or decrease any “call equivalent position” (in each case within the meaning of Section 16 of the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder) with respect to any Relevant Security, or otherwise enter into any swap, derivative or other transaction or arrangement that Transfers to another, in whole or in part, any economic consequence of ownership of a Relevant Security, whether or not such transaction is to be settled by delivery of Relevant Securities, other securities, cash or other consideration. As used herein, the term “Relevant Security” means any shares of Common Stock, warrant or option to purchase Common Stock or other security of the Company that is convertible into, or exercisable or exchangeable for Common Stock or equity securities of the Company, in each case that are owned by the undersigned on the Effective Date or acquired by the undersigned during the Lock-Up Period.

In addition, the undersigned hereby agrees that, without the prior written consent of the Representative, during the Lock-Up Period and except with respect to the rights of the undersigned to participate in the Public Offering, the undersigned will not: (i) file or participate in the filing with the Securities and Exchange Commission of any registration statement, or circulate or participate in the circulation of any preliminary or final prospectus or other disclosure document with respect to any proposed offering or sale of a Relevant Security and (ii) exercise any rights the undersigned may have to require registration with the Securities and Exchange Commission of any proposed offering or sale of a Relevant Security.

In addition, to the extent the Company ceases to be an “Emerging Growth Company” at any time prior to the expiration of the Lock-Up Period and if: (i) the Company issues an earnings release or material news or a material event relating to the Company occurs during the last seventeen (17) days of the Lock-Up Period, or (ii) prior to the expiration of the Lock-Up Period, the Company announces that it will release earnings results during the sixteen (16)-day period beginning on the last day of the Lock-Up Period, the restrictions imposed by this Agreement shall continue to apply until the expiration of the eighteen (18)-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event, as applicable, unless the Representative waives, in writing, such extension or the undersigned receives prior written confirmation from the Representative or the Company that the restrictions imposed herein have expired.

In furtherance of the undersigned’s obligations hereunder, the undersigned hereby authorizes the Company during the Lock-Up Period to cause any transfer agent for the Relevant Securities to decline to transfer, and to note stop transfer restrictions on the stock register and other records relating to, Relevant Securities for which the undersigned is the record holder and the transfer of which would be a violation of this lock-up agreement and, in the case of Relevant Securities for which the undersigned is the beneficial but not the record holder, agrees during the Lock-Up Period to cause the record holder to cause the relevant transfer agent to decline to transfer, and to note stop transfer restrictions on the stock register and other records relating to, such Relevant Securities to the extent such transfer would be violation of this lock-up agreement.

Notwithstanding the foregoing, the undersigned may transfer the undersigned’s Relevant Securities (i) as a bona fide gift or gifts, (ii) for bona fide financial and estate planning purposes, including, but not limited to, transfers to any trust for the direct or indirect benefit of the undersigned or the immediate family of the undersigned, (iii) if the undersigned is a corporation, partnership, limited liability company, trust or other business entity (1) to another corporation, partnership, limited liability company, trust or other business entity that is a direct or indirect affiliate (as defined in Rule 405 promulgated under the Securities Act of 1933, as amended) of the undersigned or (2) to limited partners, limited liability company members or stockholders of the undersigned, (iv) if the undersigned is a trust, to the beneficiary of such trust, (v) by testate succession or intestate succession, (vi) by operation of law, such as pursuant to a qualified domestic order or in connection with a divorce decree or settlement, provided, in the case of clauses (i)-(vi), that such transfer shall not involve a disposition for value and the transferee agrees in writing with the Underwriters and the Company to be bound by the terms of this lock-up agreement, (vii) to the Company pursuant to any contractual arrangement that provides for the repurchase of the undersigned’s Common Stock or such other securities by the Company or in connection with the termination of the undersigned’s employment or other service relationship

with the Company, or (viii) pursuant to a bona fide third party tender offer, merger, consolidation or other similar transaction made to all holders of the Company’s capital stock involving a change of control of the Company, provided that in the event that the tender offer, merger, consolidation or other such transaction is not completed, the undersigned’s Common Stock shall remain subject to the restrictions set forth herein, and provided further that the consideration per share of Common Stock paid in such transaction shall be no less than the public offering price per share paid in the Public Offering. For purposes of this Agreement, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin.

In addition, the foregoing restrictions shall not apply to (i) the exercise of stock options granted pursuant to the Company’s equity incentive plans (whether on a cash or cashless basis) or the conversion or redemption of outstanding convertible securities, provided that such restrictions shall apply to any of the Relevant Securities issued upon such exercise, conversion or redemption, as the case may be, (ii) the establishment or modification of any contract, instruction or plan (a “Plan”) that satisfies all of the requirements of Rule 10b5-1(c)(1)(i)(B) under the Securities Exchange Act of 1934, as amended; provided that no sales of the undersigned’s Relevant Securities shall be made pursuant to such a Plan prior to the expiration of the Lock-Up Period (as such may have been extended pursuant to the provisions hereof), or (iii) transfers of the Relevant Securities to the Company in transactions exempt from Section 16(b) of the Exchange Act, provided that no filing by any party under Section 16(a) of the Exchange Act shall be required or shall be made voluntarily in connection with such transfer.

If the undersigned is an officer or director of the Company, the undersigned acknowledges that the Company has agreed in the Underwriting Agreement to announce the impending release or waiver by press release through a major news service at least two (2) business days before the effective date of the release or waiver. Any release or waiver granted by the Representative hereunder to any such officer or director shall only be effective two (2) business days after the publication date of such press release. The provisions of this paragraph will not apply if (a) the release or waiver is effected solely to permit a transfer not for consideration and (b) the transferee has agreed in writing to be bound by the same terms described in this Agreement to the extent and for the duration that such terms remain in effect at the time of the transfer.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this letter agreement and that this letter agreement constitutes the legal, valid and binding obligation of the undersigned, enforceable in accordance with its terms. Upon request, the undersigned will execute any additional documents necessary in connection with enforcement hereof. Any obligations of the undersigned shall be binding upon the successors and assigns of the undersigned from the date first above written.

The undersigned understands that, if the Underwriting Agreement or the Registration Statement does not become effective, the Company or the Representative informs the other that it does not intend to proceed with the Public Offering, or if the Underwriting Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Securities to be sold thereunder, the undersigned shall be released from all obligations under this letter agreement.

The undersigned, whether or not participating in the Public Offering, understands that the Underwriters are entering into the Underwriting Agreement and proceeding with the Public Offering in reliance upon this letter agreement.

This lock-up agreement shall be governed by and construed in accordance with the laws of the State of New York, without regard to the conflict of laws principles thereof. Delivery of a signed copy of this letter agreement by facsimile or e-mail/.pdf transmission shall be effective as delivery of the original hereof.
