Exhibit 10.15

LOAN AGREEMENT

THIS LOAN AGREEMENT (this “Loan Agreement”) dated effective as of September 8, 2017 (the “Effective Date”) is made and executed by and between Jain Investments, LLC, a Texas limited liability company (the “Lender”) and Arog Pharmaceuticals, Inc., a Delaware corporation (the “Borrower”).

WHEREAS, Lender wishes to provide, and Borrower wishes to accept, certain loans pursuant to reasonable terms as set forth herein.

NOW THEREFORE, in consideration of the premises set forth above and the promises contained herein, the sufficiency and receipt of which are hereby acknowledged, the parties agree as follows:

1.   Line of Credit. Lender agrees to make available to Borrower an operating line of credit (the “Line of Credit”) in an amount of principal not to exceed Four Million and No/100 Dollars ($4,000,000) (the “Maximum Amount”). Advances shall be made under the Line of Credit only upon written request, signed by an authorized officer of Borrower, specifying in reasonable detail the intended use of the funds and the requested amount of principal to be advanced, up to the Maximum Amount. All funds advanced pursuant to this Section 1 (each an “Advance”) shall be evidenced by the Promissory Note substantially in the form attached hereto as Exhibit A (the “Promissory Note”). Borrower authorizes Lender to endorse on Schedule A to the Promissory Note the date and principal amount of each Advance, with each endorsement to be binding on the Borrower absent manifest error; provided that the failure of Lender to make any such endorsement shall not affect the obligation of Borrower to repay each Advance and to pay interest accrued thereon and other sums payable under the Promissory Note.

2.   First Advance. Upon signing this Agreement, Lender agrees to make a first Advance to Borrower in the amount of One Million and No/100 Dollars ($1,000,000), to be used for general corporate business purposes (the “First Advance”). The First Advance shall bear interest from the date advanced until the date of repayment at a simple interest rate equal to 2.58% per annum. The parties hereby agree and acknowledge that the interest rate of the First Advance set forth herein is consistent with prevailing fair market rates for similar loans. Accrued interest on the First Advance shall be due and payable at maturity. Lender’s calculations of accrued interest on the First Advance shall be binding and conclusive in the absence of manifest error.

3.   Interest. All subsequent Advances after the First Advance under the Line of Credit shall bear interest from the date of such Advance until the date of repayment at such simple annual interest rate as shall be fixed on the date the Advance is made in accordance with the interest rate. Such interest shall be calculated based on a 365-day year and shall be paid from the actual number of days elapsed. Accrued interest on amounts borrowed under this Agreement shall be due and payable at maturity. Lender’s calculations of accrued interest hereunder shall be binding and conclusive in the absence of manifest error.

4.   Repayment. The outstanding principal balance and accrued but unpaid interest under the Promissory Note is due and payable in full upon the demand by Lender. Prior to such

demand, Borrower shall have the right, upon payment of all accrued but unpaid interest, to repay without premium or penalty, all or part of the outstanding principal under the Promissory Note. Any such repayment of principal by the Borrower, unless the repayment is the result of a demand for payment in full by the Lender, shall increase the availability of funds which the Borrower may re-borrow up to the Maximum Amount.

5.   Term. The term of this Agreement shall be for a period of ten (10) years from the Effective Date. Thereafter, this Agreement may be renewed for additional five-year terms upon the mutual written consent of both parties. If not renewed, this Agreement shall expire, and the outstanding principal balance of all Advances shall mature and be due and payable in full, together with all interest thereon.

6.   Representations. Borrower makes the following representations and warranties, which shall survive the execution of this Loan Agreement and the making of each Advance hereunder:

a.   Borrower is a corporation duly organized, validly existing and in good standing under the laws of the State of Delaware;

b.   Borrower has the corporate power to enter into and perform this Loan Agreement and to borrower hereunder and has taken all necessary corporate actions to authorize the borrowings upon the terms and conditions of this Loan Agreement and to authorize the borrowings upon the terms and conditions of this Loan Agreement and to authorize the execution, deliver and performance of this Loan Agreement in accordance with its terms; and

c.   This Loan Agreement and the Promissory Note are valid and legally enforceable against the Borrower in accordance with their terms except to the extent that enforcement thereof may be limited by bankruptcy, insolvency, or similar laws affecting the enforcement of creditors’ rights generally.

7.  Covenants.

a.   In the event of a sale, merger, consolidation, reorganization or similar transaction or series of transactions as a result of which the stockholders of Borrower immediately prior to such transaction or series of transactions hold less than a majority of the equity entitled to vote in the election of directors of Borrower (a “Change of Control”) or an Initial Public Offering (an “IPO”), Lender may at any time thereafter, with or without notice to the Borrower, terminate its commitment hereunder, and declare the Promissory Note, together with accrued interest thereon and any other amounts payable hereunder to be, and the Promissory Note and all such amounts shall become, immediately due and payable without presentment, demand, protest or other notice of any kind, all of which are hereby waived by Borrower;

b.   So long as this Loan Agreement shall remain in effect, Borrower shall not, without the consent of Lender, consolidate or merge with or into any other person or convey, transfer or lease all or substantially all of its assets to any person or entity; and

c.   So long as this Loan Agreement shall remain in effect, the Borrower shall not mortgage, lease or allow any liens upon its properties except liens which have not matured (including any which Borrower is contesting in good faith by adequate proceedings).

9. Increased Costs. If Lender’s cost of borrowing is increased by an amount deemed by Lender in its sole discretion to be material, Lender will provide notice thereof to Borrower as soon as practicable and Borrower shall compensate Lender for all such increased costs. Borrower may, upon receiving such a notice, terminate any applicable Advance upon payment of all outstanding amounts owed with respect thereto, including increased costs accrued to the date of such termination and owing to Lender pursuant to the foregoing. Any certificate of Lender in respect of the foregoing will be conclusive and binding upon the Borrower, absent manifest error, provided that the Lender shall determine the amounts owing to it in good faith using any reasonable averaging and attribution methods.
