2. BUYER’S REPRESENTATIONS AND WARRANTIES. Each Buyer, severally and not jointly, represents and warrants with respect to only itself to each of Semnur and Denali that:

(a) No Public Sale or Distribution. Such Buyer is acquiring the Common Shares for its own account and not with a view towards, or for resale in connection with, the public sale or distribution thereof, except pursuant to sales registered or exempted under the 1933 Act; provided, however, that by making the representations herein, such Buyer does not agree to hold any of the Common Shares for any minimum or other specific term and reserves the right to dispose of the Common Shares at any time in accordance with or pursuant to a registration statement or an exemption under the 1933 Act. Such Buyer is acquiring the Common Shares hereunder in the ordinary course of its business. Such Buyer does not presently have any agreement or understanding, directly or indirectly, with any Person (as defined below) to distribute any of the Common Shares.  For purposes of this Agreement, “Person” means an individual, a limited liability company, a partnership, a joint venture, a corporation, a trust, an unincorporated organization and a government or any department or agency thereof.

(b) Accredited Investor Status. Such Buyer is an “accredited investor” as that term is defined in Rule 501(a) of Regulation D.

(c) Reliance on Exemptions. Such Buyer understands that the Common Shares are being offered and sold to it in reliance on specific exemptions from the registration requirements of United States federal and state securities laws and that Semnur and Denali are relying in part upon the truth and accuracy of, and such Buyer’s compliance with, the representations, warranties, agreements, acknowledgments and understandings of such Buyer set forth herein in order to determine the availability of such exemptions and the eligibility of such Buyer to acquire the Common Shares.

(d) Information. Such Buyer and its advisors, if any, have been furnished with all materials relating to the business, finances and operations of Semnur, Denali and New Semnur and materials relating to the offer and sale of the Common Shares that have been requested by such Buyer. Such Buyer and its advisors, if any, have been afforded the opportunity to ask questions of Semnur and Denali. Neither such inquiries nor any other due diligence investigations conducted by such Buyer or its advisors, if any, or its representatives shall modify, amend or affect such Buyer’s right to rely on Semnur’s and Denali’s representations and warranties contained herein. Such Buyer understands that its investment in the Common Shares involves a high degree of risk. Such Buyer has sought such accounting, legal and tax advice as it has considered necessary to make an informed investment decision with respect to its acquisition of the Common Shares.

(e) No Governmental Review. Such Buyer understands that no United States federal or state agency or any other government or governmental agency has passed on or made any recommendation or endorsement of the Common Shares or the fairness or suitability of the investment in the Common Shares nor have such authorities passed upon or endorsed the merits of the offering of the Common Shares.

3

(f) Transfer or Resale. Such Buyer understands that: (i) the Common Shares have not been and are not being registered under the 1933 Act or any state securities laws, and may not be offered for sale, sold, assigned or transferred unless (A) subsequently registered thereunder, (B) such Buyer shall have delivered to Semnur an opinion of counsel, in a form reasonably acceptable to Semnur, to the effect that such Common Shares to be sold, assigned or transferred may be sold, assigned or transferred pursuant to an exemption from such registration, or (C) such Buyer provides Semnur with reasonable assurance that such Common Shares can be sold, assigned or transferred pursuant to Rule 144 or Rule 144A promulgated under the 1933 Act, as amended (or a successor rule thereto) (collectively, “Rule 144”); and (ii) any sale of the Common Shares made in reliance on Rule 144 may be made only in accordance with the terms of Rule 144 and further, if Rule 144 is not applicable, any resale of the Common Shares under circumstances in which the seller (or the Person through whom the sale is made) may be deemed to be an underwriter (as that term is defined in the 1933 Act) may require compliance with some other exemption under the 1933 Act or the rules and regulations of the SEC thereunder.

(g) Legends. Such Buyer understands that the certificates or other instruments representing the Common Shares, except as set forth below, shall bear a restrictive legend in the following form (and a stop-transfer order may be placed against transfer of such stock certificates):

THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS. THE SECURITIES MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED (I) IN THE ABSENCE OF (A) AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR (B) AN OPINION OF COUNSEL SELECTED BY THE HOLDER, IN A FORM REASONABLY ACCEPTABLE TO THE COMPANY, THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT OR (II) UNLESS SOLD OR ELIGIBLE TO BE SOLD PURSUANT TO RULE 144 OR RULE 144A UNDER SAID ACT.

The legend set forth above shall be removed and New Semnur shall issue a certificate without such legend to the holder of the Common Shares upon which it is stamped or issue to such holder by electronic delivery at the applicable balance account at DTC, if (i) such Common Shares are registered for resale under the 1933 Act or exchanged for other securities in a transaction registered under the 1933 Act, (ii) in connection with a sale, assignment or other transfer, such holder provides Semnur with an opinion of counsel, in a form reasonably acceptable to Semnur, to the effect that such sale, assignment or transfer of the Common Shares may be made without registration under the applicable requirements of the 1933 Act, or (iii) the Common Shares can be sold, assigned or transferred pursuant to Rule 144 or Rule 144A.

(h) Validity; Enforcement. This Agreement and the other Transaction Documents (as defined below) to which such Buyer is a party have been duly and validly authorized, executed and delivered on behalf of such Buyer and shall constitute the legal, valid and binding obligations of such Buyer enforceable against such Buyer in accordance with their respective terms, except as such enforceability may be limited by general principles of equity or to applicable bankruptcy, insolvency, reorganization, moratorium, liquidation and other similar laws relating to, or affecting generally, the enforcement of applicable creditors’ rights and remedies.

4

(i) No Conflicts. The execution, delivery and performance by such Buyer of this Agreement and the other Transaction Documents to which such Buyer is a party and the consummation by such Buyer of the transactions contemplated hereby and thereby will not (i) result in a violation of the organizational documents of such Buyer or (ii) conflict with, or constitute a default (or an event which with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, any agreement, indenture or instrument to which such Buyer is a party, or (iii) result in a violation of any law, rule, regulation, order, judgment or decree (including federal and state securities laws) applicable to such Buyer, except in the case of clauses (ii) and (iii) above, for such conflicts, defaults, rights or violations which would not, individually or in the aggregate, reasonably be expected to have a material adverse effect on the ability of such Buyer to perform its obligations hereunder.

3. REPRESENTATIONS AND WARRANTIES OF SEMNUR.

Semnur represents and warrants to each of the Buyers that, as of the date hereof and as of the Closing Date:

(a) Organization and Qualification. Semnur is an entity duly organized and validly existing and in good standing under the laws of the state of Delaware, and has the requisite power and authorization to own its properties and to carry on its business as now being conducted and as presently proposed to be conducted. Semnur is duly qualified as a foreign corporation to do business and is in good standing in every jurisdiction in which its ownership of property or the nature of the business conducted by it makes such qualification necessary, except to the extent that the failure to be so qualified or be in good standing would not reasonably be expected to have a Semnur Material Adverse Effect. As used in this Agreement, “Semnur Material Adverse Effect” means any material adverse effect on the business, properties, assets, liabilities, operations, results of operations, condition (financial or otherwise) or prospects of Semnur, individually or taken as a whole, or on the transactions contemplated hereby or on the other Semnur Transaction Documents (as defined below) or by the agreements and instruments to be entered into in connection herewith or therewith, or on the authority or ability of Semnur to perform any of its obligations under any of the Semnur Transaction Documents. Semnur does not, directly or indirectly, own any of the capital stock or hold an equity or similar interest in any entity.

(b) Authorization; Enforcement; Validity. Semnur has the requisite corporate power and authority to enter into and perform its obligations under this Agreement and each of the other agreements entered into by Semnur in connection with the transactions contemplated by this Agreement (collectively, the “Semnur Transaction Documents”) and to issue the Common Shares in accordance with the terms hereof and thereof. The execution and delivery of this Agreement and the other Semnur Transaction Documents by Semnur and the consummation by Semnur of the transactions contemplated hereby and thereby, including, without limitation, the issuance of the Common Shares, have been duly authorized by Semnur’s Board of Directors and (other than filings pursuant to applicable securities laws), no further filing, consent or authorization is required by Semnur, its Board of Directors or its stockholders. This Agreement and the other Semnur Transaction Documents have been duly executed and delivered by Semnur, and constitute the legal, valid and binding obligations of Semnur, enforceable against Semnur in accordance with their respective terms, except as such enforceability may be limited by general principles of equity or applicable bankruptcy, insolvency, reorganization, moratorium, liquidation or similar laws relating to, or affecting generally, the enforcement of applicable creditors’ rights and remedies.

5

(c) Issuance of Common Shares. The issuance of the Common Shares is duly authorized and, upon issuance in accordance with the terms of the Semnur Transaction Documents, the Common Shares shall be validly issued and free from all preemptive or similar rights (except for those which have been validly waived prior to the date hereof), taxes, liens and charges and other encumbrances with respect to the issue thereof and the Common Shares shall be fully paid and nonassessable with the holders being entitled to all rights accorded to a holder of New Semnur Common Stock. Assuming the accuracy of each of the representations and warranties set forth in Section 3, the offer and issuance by Semnur of the Common Shares is exempt from registration under the 1933 Act.

(d) No Conflicts. Except as disclosed in Schedule 3(d), the execution, delivery and performance of the Semnur Transaction Documents by Semnur and the consummation by Semnur of the transactions contemplated hereby and thereby (including, without limitation, the issuance of the Common Shares) will not (i) result in a violation of Semnur’s Certificate of Incorporation (as amended from time to time, the “Semnur Certificate of Incorporation”) or Semnur’s Bylaws (as amended from time to time, the “Semnur Bylaws”), (ii) conflict with, or constitute a default (or an event which with notice or lapse of time or both would become a default) in any respect under, or give to others any rights of termination, amendment, acceleration or cancellation of, any agreement, indenture or instrument to which Semnur is a party, or (iii) result in a violation of any law, rule, regulation, order, judgment or decree (including foreign, federal and state securities laws and regulations) and including all applicable foreign, federal, state laws, rules and regulations applicable to Semnur or by which any property or asset of Semnur is bound or affected, except, in the case of clauses (ii) and (iii) above, as would not have or reasonably be expected to result in a Semnur Material Adverse Effect.

(e) Consents. Except as disclosed in Schedule 3(e), Semnur is not required to obtain any consent from, authorization or order of, or make any filing or registration with (other than filings pursuant to applicable securities laws), any court, governmental agency or any regulatory or self-regulatory agency or any other Person in order for it to execute, deliver or perform any of its obligations under or contemplated by the Semnur Transaction Documents, in each case, in accordance with the terms hereof or thereof. All consents, authorizations, orders, filings and registrations which Semnur is required to obtain pursuant to the preceding sentence have been obtained or effected on or prior to the Closing Date (or in the case of filings detailed above, will be made timely after the Closing Date).

(f) Acknowledgment Regarding Buyer’s Purchase of Common Shares. Semnur acknowledges and agrees that each Buyer is acting solely in the capacity of an arm’s length purchaser with respect to the Semnur Transaction Documents and the transactions contemplated hereby and thereby and that no Buyer is (i) an officer or director of Semnur, (ii) an “affiliate” of Semnur (as defined in Rule 144) or (iii) to the knowledge of Semnur, a “beneficial owner” of more than 10% of the New Semnur Common Stock (as defined for purposes of Rule 13d-3 of the 1934 Act). Semnur further acknowledges that no Buyer is acting as a financial advisor or fiduciary of Semnur (or in any similar capacity) with respect to the Semnur Transaction Documents and the transactions contemplated hereby and thereby, and any advice given by a Buyer or any of its representatives or agents in connection with the Semnur Transaction Documents and the transactions contemplated hereby and thereby is merely incidental to such Buyer’s purchase of the Common Shares. Semnur further represents to each Buyer that Semnur’s decision to enter into the Semnur Transaction Documents has been based solely on the independent evaluation by Semnur and its representatives.

6

(g) No General Solicitation; Placement Agent’s Fees. Neither Semnur nor its affiliates, nor any Person acting on its or their behalf, has engaged in any form of general solicitation or general advertising (within the meaning of Regulation D) in connection with the offer or sale of the Common Shares. Semnur shall be responsible for the payment of any placement agent’s fees, financial advisory fees, or brokers’ commissions (other than for Persons engaged by any Buyer or its investment advisor) relating to or arising out of the transactions contemplated hereby, including, without limitation, placement agent fees payable to JW Capital (the “Placement Agent”) in connection with the sale of the Common Shares. Semnur shall pay, and hold each Buyer harmless against, any liability, loss or expense (including, without limitation, attorney’s fees and out-of-pocket expenses) arising in connection with any such claim. Semnur acknowledges that it has engaged the Placement Agent in connection with the sale of the Common Shares.

(h) No Integrated Offering. Neither Semnur, nor any of its affiliates, nor any Person acting on its behalf has, directly or indirectly, made any offers or sales of any security or solicited any offers to buy any security, under circumstances that would require registration of the issuance of any of the Common Shares under the 1933 Act, whether through integration with prior offerings or otherwise, or cause this offering of the Common Shares to require approval of stockholders of Semnur for purposes of the 1933 Act or any applicable stockholder approval provisions, including, without limitation, under the rules and regulations of any exchange or automated quotation system on which any of the securities of Semnur or Denali are listed or designated for quotation. Neither Semnur nor its affiliates nor any Person acting on their behalf will take any action or steps that would require registration of the issuance of any of the Common Shares under the 1933 Act or cause the offering of any of the Common Shares to be integrated with other offerings for purposes of any such applicable stockholder approval provisions.

(i) Application of Takeover Protections. Semnur and its Board of Directors have taken all necessary action, if any, in order to render inapplicable any control share acquisition, interested stockholder, business combination, poison pill (including, without limitation, any distribution under a rights agreement) or other similar anti-takeover provision under the Semnur Certificate of Incorporation, the Semnur Bylaws or other organizational documents or the laws of the jurisdiction of its formation which is or could become applicable to any Buyer as a result of the transactions contemplated by this Agreement, including, without limitation, Semnur’s issuance of the Common Shares and any Buyer’s ownership of the Common Shares.

7

(j) Form S-4; Financial Statements. As of each filing date of the registration statement on Form S-4 filed by Denali (File No. 333-283019) (as amended from time to time, the “Form S-4”) or any amendment thereto, the sections of the Form S-4 titled “Business of Semnur,” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations of Semnur”, did not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. As of each filing date of the Form S-4 or any amendment thereto, the financial statements of Semnur included in the Form S-4 (the “Semnur Financial Statements”) complied as to form in all material respects with applicable accounting requirements and the published rules and regulations of the SEC with respect thereto. The Semnur Financial Statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”), consistently applied during the periods involved (except (i) as may be otherwise indicated in the Semnur Financial Statements or the notes thereto, or (ii) in the case of unaudited interim statements, to the extent they may exclude footnotes or may be condensed or summary statements) and fairly present in all material respects the financial position of Semnur as of the dates thereof and the results of its operations and cash flows for the periods then ended (subject, in the case of unaudited statements, to normal year-end audit adjustments which will not be material, either individually or in the aggregate).

(k) Absence of Certain Changes. Since March 31, 2025, there has been no material adverse change and no material adverse development in the business, assets, liabilities, properties, operations, condition (financial or otherwise), results of operations or prospects of Semnur. Semnur has not taken any steps to seek protection pursuant to any law or statute relating to bankruptcy, insolvency, reorganization, receivership, liquidation or winding up, nor does Semnur have any knowledge or reason to believe that any of its creditors intend to initiate involuntary bankruptcy proceedings or any actual knowledge of any fact which would reasonably lead a creditor to do so.

(l) Conduct of Business; Regulatory Permits. Semnur is not in violation of any term of or in default under the Semnur Certificate of Incorporation or the Semnur Bylaws. Semnur is not in violation of any judgment, decree or order or any statute, ordinance, rule or regulation applicable to Semnur, and Semnur will not conduct its business in violation of any of the foregoing, except in all cases for possible violations which would not, individually or in the aggregate, reasonably be expected to have a Semnur Material Adverse Effect. Semnur possesses all certificates, authorizations and permits issued by the appropriate foreign, federal or state regulatory authorities necessary to conduct their respective businesses, except where the failure to possess such certificates, authorizations or permits would not have, individually or in the aggregate, a Semnur Material Adverse Effect, and Semnur has not received any notice of proceedings relating to the revocation or modification of any such certificate, authorization or permit.

(m) Foreign Corrupt Practices. Neither Semnur, nor to Semnur’s knowledge, any of its directors, officers, employees or agents have, directly or indirectly, made, offered, promised or authorized any payment or gift of any money or anything of value to or for the benefit of any “foreign official” (as such term is defined in the U.S. Foreign Corrupt Practices Act of 1977, as amended (the “FCPA”)), foreign political party or official thereof or candidate for foreign political office for the purpose of (i) influencing any official act or decision of such official, party or candidate, (ii) inducing such official, party or candidate to use his, her or its influence to affect any act or decision of a foreign governmental authority, or (iii) securing any improper advantage, in the case of (i), (ii) and (iii) above in order to assist Semnur or any of its affiliates in obtaining or retaining business for or with, or directing business to, any person.

(p) Indebtedness and Other Contracts. Except (i) as specifically disclosed, reflected or reserved against on the Semnur Financial Statements, (ii) for Liabilities (as defined below) and obligations of a similar nature and in similar amounts incurred in the ordinary course of business since April 1, 2025, (iii) for Liabilities incurred in connection with the negotiation, preparation or execution of the Merger Agreement or the Semnur Transaction Documents, the performance of their respective covenants or agreements in the Merger Agreement or the Semnur Transaction Documents or the consummation of the transactions contemplated hereby or thereby and (iv) for Liabilities that do not, and would not reasonably be expected, individually or in the aggregate, to have a Semnur Material Adverse Effect, Semnur does not have any Liabilities of the type required to be set forth on a balance sheet in accordance with GAAP consistently applied in accordance with past practice. For purposes of this Agreement, “Liabilities” means all liabilities, Indebtedness, claims, or obligations of any nature (whether absolute, accrued, contingent or otherwise, whether known or unknown, whether direct or indirect, whether matured or unmatured and whether due or to become due).

(r) Insurance. Semnur is insured by insurers of recognized financial responsibility against such losses and risks and in such amounts as management of Semnur believes to be prudent and customary in the businesses in which Semnur is engaged. Semnur has no reason to believe that it will be unable to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its business at a cost that would not have a Semnur Material Adverse Effect.

(s) Employee Relations. Semnur is not a party to any collective bargaining agreement or employs any member of a union. Semnur believes that its relations with its employees are good. No executive officer (as defined in Rule 501(f) promulgated under the 1933 Act) or other key employee of Semnur has notified Semnur that such officer intends to leave Semnur or otherwise terminate such officer’s employment with Semnur. No executive officer or other key employee of Semnur is, or is now expected to be, in violation of any material term of any employment contract, confidentiality, disclosure or proprietary information agreement, non-competition agreement, or any other contract or agreement or any restrictive covenant, and the continued employment of each such executive officer or other key employee (as the case may be) does not subject Semnur to any liability with respect to any of the foregoing matters. Semnur is in compliance with all federal, state, local and foreign laws and regulations respecting labor, employment and employment practices and benefits, terms and conditions of employment and wages and hours, except where failure to be in compliance would not, either individually or in the aggregate, reasonably be expected to result in a Semnur Material Adverse Effect.

10

(g) All lock-up provisions and other restrictions on transfer applicable to the equity securities of Denali held by Denali Capital Global Investments LLC (the “Sponsor”) pursuant to any agreements or arrangements in effect prior to the execution of this Agreement, including that certain Letter Agreement, dated as of April 6, 2022, by and among Denali Capital Acquisition Corp., Sponsor and certain security holders named therein and the other agreements disclosed in the SEC Documents, shall remain in full force and effect in accordance with their terms immediately following the Closing, and neither Denali nor the Sponsor shall have taken any action to waive, amend, terminate, or otherwise release the Sponsor from such provisions or restrictions.

8. TERMINATION. In the event that the Closing shall not have occurred with respect to a Buyer on or before December 31, 2025 due to Semnur’s, Denali’s or such Buyer’s failure to satisfy the conditions set forth in Sections 6 and 7 above (and the nonbreaching party’s failure to waive such unsatisfied condition(s)), the Buyer, if such Buyer is the nonbreaching party, or Semnur, if Semnur is the nonbreaching party, shall have the option to terminate this Agreement with respect to such Buyer, if such Buyer is the breaching party, or with respect to Semnur and Denali, if Semnur or Denali are the breaching party, at the close of business on such date by delivering a written notice to that effect to each other party to this Agreement and without liability of any party to any other party.

9. MISCELLANEOUS.

(a) Governing Law; Jurisdiction; Jury Trial. All questions concerning the construction, validity, enforcement and interpretation of this Agreement shall be governed by the internal laws of the State of New York, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of New York or any other jurisdictions) that would cause the application of the laws of any jurisdictions other than the State of New York. Each party hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in The City of New York, Borough of Manhattan, for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is brought in an inconvenient forum or that the venue of such suit, action or proceeding is improper. Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof to such party at the address for such notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law. EACH PARTY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION WITH OR ARISING OUT OF THIS AGREEMENT OR ANY TRANSACTION CONTEMPLATED HEREBY.

(b) Counterparts. This Agreement may be executed in two or more identical counterparts, all of which shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party; provided that a facsimile or .pdf signature shall be considered due execution and shall be binding upon the signatory thereto with the same force and effect as if the signature were an original, not a facsimile or .pdf signature.

(c) Headings. The headings of this Agreement are for convenience of reference and shall not form part of, or affect the interpretation of, this Agreement.

22

(d) Severability. If any provision of this Agreement is prohibited by law or otherwise determined to be invalid or unenforceable by a court of competent jurisdiction, the provision that would otherwise be prohibited, invalid or unenforceable shall be deemed amended to apply to the broadest extent that it would be valid and enforceable, and the invalidity or unenforceability of such provision shall not affect the validity of the remaining provisions of this Agreement so long as this Agreement as so modified continues to express, without material change, the original intentions of the parties as to the subject matter hereof and the prohibited nature, invalidity or unenforceability of the provision(s) in question does not substantially impair the respective expectations or reciprocal obligations of the parties or the practical realization of the benefits that would otherwise be conferred upon the parties. The parties will endeavor in good faith negotiations to replace the prohibited, invalid or unenforceable provision(s) with a valid provision(s), the effect of which comes as close as possible to that of the prohibited, invalid or unenforceable provision(s).

(e) Entire Agreement; Amendments. This Agreement and the other Transaction Documents supersede all other prior oral or written agreements between Semnur, Denali, their affiliates and Persons acting on their behalf, on the one hand, and the Buyers, their affiliates and Persons acting on their behalf, on the other hand, with respect to the matters discussed herein, and this Agreement, the other Transaction Documents and the instruments referenced herein and therein contain the entire understanding of the parties with respect to the matters covered herein and therein and, except as specifically set forth herein or therein, none of Semnur, Denali nor any Buyer makes any representation, warranty, covenant or undertaking with respect to such matters. No provision of this Agreement may be amended other than by an instrument in writing signed by Semnur, Denali and the holders of at least a majority of the aggregate amount of Common Shares issued and issuable hereunder, and any amendment to this Agreement made in conformity with the provisions of this Section 9(e) shall be binding on all Buyers and holders of Common Shares, Semnur and Denali; provided, that any such amendment or waiver that complies with the foregoing but that disproportionately, materially and adversely affects the rights and obligations of any Buyer relative to the comparable rights and obligations of the other Buyers shall require the prior written consent of such adversely affected Buyer (for the avoidance of doubt, participation by any Buyer in an unrelated financing by Semnur shall not be deemed to disproportionately affect the Buyers who do not participate in such financing). No provisions hereto may be waived other than by an instrument in writing signed by the party against whom enforcement is sought. No such amendment shall be effective to the extent that it applies to less than all of the Buyers or holders of the applicable Common Shares then outstanding.

(f) Notices. Any notices, consents, waivers or other communications required or permitted to be given under the terms of this Agreement or any of the other Transaction Documents must be in writing and will be deemed to have been delivered: (i) upon receipt, when delivered personally; (ii) upon delivery, when sent by electronic mail (provided that the sending party does not receive an automated rejection notice); or (iii) one (1) business day after deposit with an overnight courier service, in each case properly addressed to the party to receive the same.

(g) Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties and their respective successors and assigns, including any purchasers of the Common Shares. A Buyer may assign some or all of its rights hereunder without the consent of Semnur or Denali, in which event such assignee shall be deemed to be a Buyer hereunder with respect to such assigned rights.

(h) Third Party Beneficiaries. The Placement Agent shall be a third party beneficiary of the representations and warranties of the Buyers in Section 2, the representations and warranties of Semnur in Section 3 and the representations and warranties of Denali in Section 4. This Agreement is intended for the benefit of the parties hereto and their respective permitted successors and assigns, and is not for the benefit of, nor may any provision hereof be enforced by, any other Person, except that each Indemnitee (as defined below) shall have the right to enforce the obligations of Semnur and Denali with respect to Section 9(k) and as otherwise set forth in this Section 9(h).

(i) Survival. Unless this Agreement is terminated under Section 9, the representations and warranties of Semnur, Denali and the Buyers contained in Sections 2, 3 and 4, and the agreements and covenants set forth in Sections 5 and 9 shall survive the Closing. Each Buyer, and each of Semnur and Denali, shall be responsible only for its own representations, warranties, agreements and covenants hereunder.

(j) Further Assurances. Each party shall do and perform, or cause to be done and performed, all such further acts and things, and shall execute and deliver all such other agreements, certificates, instruments and documents, as any other party may reasonably request in order to carry out the intent and accomplish the purposes of this Agreement and the consummation of the transactions contemplated hereby.

24

(k) Indemnification.

(i) In consideration of each Buyer’s execution and delivery of the Transaction Documents and acquiring the Common Shares thereunder and in addition to all of Semnur’s other obligations under the Transaction Documents, Semnur shall defend, protect, indemnify and hold harmless each Buyer and each other holder of the Common Shares and all of their stockholders, partners, members, officers, directors, employees and direct or indirect investors and any of the foregoing Persons’ agents or other representatives (including, without limitation, those retained in connection with the transactions contemplated by this Agreement) (collectively, the “Indemnitees”) from and against any and all actions, causes of action, suits, claims, losses, costs, penalties, fees, liabilities and damages, and expenses in connection therewith (irrespective of whether any such Indemnitee is a party to the action for which indemnification hereunder is sought), and including attorneys’ fees and disbursements (the “Indemnified Liabilities”), incurred by any Indemnitee as a result of, or arising out of, or relating to (A) any misrepresentation or breach of any representation or warranty made by Semnur in the Transaction Documents or any other certificate, instrument or document of Semnur contemplated hereby or thereby, (B) any breach of any covenant, agreement or obligation of Semnur contained in the Transaction Documents or any other certificate, instrument or document of Semnur contemplated hereby or thereby or (C) any cause of action, suit or claim brought or made against such Indemnitee by a third party (including for these purposes a derivative action brought on behalf of Semnur or Denali) and arising out of or resulting from (I) the execution, delivery, performance or enforcement of the Transaction Documents or any other certificate, instrument or document contemplated hereby or thereby, or (II) the status of such Buyer or holder of the Common Shares as an investor in Semnur pursuant to the transactions contemplated by the Transaction Documents. To the extent that the foregoing undertaking by Semnur may be unenforceable for any reason, Semnur shall make the maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities that is permissible under applicable law.

(ii) In consideration of each Buyer’s execution and delivery of the Transaction Documents and acquiring the Common Shares thereunder and in addition to all of Denali’s other obligations under the Transaction Documents, Denali shall defend, protect, indemnify and hold harmless the Indemnitees from and against any and all Indemnified Liabilities incurred by any Indemnitee as a result of, or arising out of, or relating to (A) any misrepresentation or breach of any representation or warranty made by Denali in the Transaction Documents or any other certificate, instrument or document contemplated hereby or thereby, (B) any breach of any covenant, agreement or obligation of Denali contained in the Transaction Documents or any other certificate, instrument or document contemplated hereby or thereby or (C) any cause of action, suit or claim brought or made against such Indemnitee by a third party (including for these purposes a derivative action brought on behalf of Semnur or Denali) and arising out of or resulting from (I) the execution, delivery, performance or enforcement of the Transaction Documents or any other certificate, instrument or document contemplated hereby or thereby, or (II) the status of such Buyer or holder of the Common Shares as an investor in Denali pursuant to the transactions contemplated by the Transaction Documents. To the extent that the foregoing undertaking by Denali may be unenforceable for any reason, Denali shall make the maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities that is permissible under applicable law.

25

(l) No Strict Construction. The language used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent, and no rules of strict construction will be applied against any party.

(m) Remedies. Each Buyer and each holder of the Common Shares shall have all rights and remedies set forth in the Transaction Documents and all rights and remedies which such holders have been granted at any time under any other agreement or contract and all of the rights which such holders have under any law. Any Person having any rights under any provision of this Agreement shall be entitled to enforce such rights specifically (without posting a bond or other security), to recover damages by reason of any breach of any provision of this Agreement and to exercise all other rights granted by law. Furthermore, each of Semnur and Denali recognizes that in the event that it fails to perform, observe, or discharge any or all of its obligations under the Transaction Documents, any remedy at law may prove to be inadequate relief to the Buyers. Each of Semnur and Denali therefore agrees that the Buyers shall be entitled to seek temporary and permanent injunctive relief in any such case without the necessity of proving actual damages and without posting a bond or other security.

(n) Independent Nature of Buyers’ Obligations and Rights. The obligations of each Buyer under each Transaction Document are several and not joint with the obligations of any other Buyer, and no Buyer shall be responsible in any way for the performance of the obligations of any other Buyer under any Transaction Document. Nothing contained herein or in any other Transaction Document, and no action taken by any Buyer pursuant hereto or thereto, shall be deemed to constitute the Buyers as, and each of Semnur and Denali acknowledges that the Buyers do not so constitute, a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Buyers are in any way acting in concert or as a group, and neither Semnur nor Denali shall assert any such claim with respect to such obligations or the transactions contemplated by the Transaction Documents and each of Semnur and Denali acknowledges that the Buyers are not acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction Documents. Each of Semnur and Denali acknowledges and each Buyer confirms that it has independently participated in the negotiation of the transaction contemplated hereby with the advice of its own counsel and advisors. Each Buyer shall be entitled to independently protect and enforce its rights, including, without limitation, the rights arising out of this Agreement or out of any other Transaction Documents, and it shall not be necessary for any other Buyer to be joined as an additional party in any proceeding for such purpose.
