 Narrative to the Summary Compensation Table

 The elements of the compensation program for our named executive officers include: annual base salary; an annual cash (non-equity) incentive; long-term equity awards; certain health, welfare and 401(k) plan benefits. Our named executive officers also have severance benefits in their respective employment agreements (see "Agreements with Named Executive Officers" below).

 The compensation of our named executive officers is generally determined and approved at the beginning of each year or, if later, in connection with the commencement of employment of the executive, by our Board or the Compensation Committee.

 In setting base salaries and bonus opportunities and granting equity incentive awards, our compensation committee considers compensation for comparable positions in the market, the historical compensation levels of our executives, individual and corporate performance as compared to our expectations and objectives, our desire to motivate our employees to achieve short- and long-term results that are in the best interests of our stockholders, and a long-term commitment to our company. As part of this process, Dr. Gros, as our Chief Executive Officer, prepares performance evaluations for the other executive officers and recommends annual salary increases, annual stock option awards and cash bonuses to the compensation committee. The Compensation Committee conducts a performance evaluation of Dr. Gros. Prior to approving compensation for our executive officers, the compensation committee consults with the full Board.

 Base Salary

 The 2023 annual base salaries for our named executive officers are set forth in the table below:

 Non-Equity Incentive Compensation

 Our Board adopted a formal executive bonus plan ("Performance Bonus Plan") in February 2021. The purpose of the Performance Bonus Plan is to create a direct relationship between key business performance measurements and individual bonus amounts. The Performance Bonus Plan provides for bonus payments to each executive officer conditioned upon the achievement of certain performance goals established by the Compensation Committee, which may differ for each executive officer. Our Compensation Committee establishes such performance goals based on one or more established performance criteria relating to operational or financial performance.

 Each executive officer is assigned a target bonus expressed as a percentage of their base salary.

 • For 2023, Dr. Gros's target performance bonus was 60% of his base salary.

 • For 2023, Dr. Perrin's target performance bonus was 50% of his base salary.

 • For 2023, Mr. Little's target performance bonus was 40% of his base salary.

 The Compensation Committee may consider each named executive officer's individual contributions towards reaching our annual corporate goals. There is no minimum bonus percentage or amount established for the named executive officers and, thus, the bonus amounts vary from year to year based on corporate and individual performance, in each case pursuant to the terms of our Performance Bonus Plan and each executive officer's employment agreement and offer letter.

 The Board approved research and development, CMC manufacturing and financial corporate goals for 2023, with research and development and CMC manufacturing goals assigned 75% of the weighting and financial performance goals at 25% of the weighting. "Stretch" goals were also approved which provided a total potential bonus achievement of 150% of target for each executive.

 In February 2024, the Compensation Committee recommended to the Board, and the Board subsequently determined, that the 2023 corporate goals had been achieved at an aggregate level of 85%, with the final bonus payment adjusted for attainment of individual performance goals. As a result, in February 2024, the Compensation Committee recommended and the Board approved, the following bonuses to our named executive officers for performance in 2023:

 Equity Compensation

 We believe that our ability to grant equity-based awards is a valuable and necessary compensation tool that aligns the long-term financial interests of our employees, consultants and directors with the financial interests of our stockholders. In

 addition, we believe that our ability to grant options and other equity-based awards helps us to attract, retain and motivate employees, consultants, and directors, and encourages them to devote their best efforts to our business and financial success.

 Our named executive officers and other employees will generally be provided annual equity awards.

 In May 2023, we issued stock option awards to our named executive officers and other employees with both time-based and performance-based vesting requirements totaling 7,381,857 stock options, with 1,476,372 of the granted stock options subject to our customary time-based vesting schedule. The remaining 5,905,485 stock options granted are subject to both customary time-based vesting requirements and performance-based vesting requirements that are based on the same clinical development milestones applicable to the second ("Second Closing") and third closings ("Third Closing") of the Securities Purchase Agreement (the "Securities Purchase Agreement") entered into on April 28, 2023 with certain institutional and accredited investors (the "Purchasers") in connection with a private offering of securities (the "Private Placement"). In an initial closing (the "Initial Closing") of the Securities Purchase Agreement on May 5, 2023, we issued an aggregate of 15,151,518 shares of our common stock or pre-funded warrants in lieu thereof (the "Pre-Funded Warrants") and common stock warrants (the "Common Warrants") exercisable for a five-year term, at an exercise price of $3.00 per share, into an aggregate of 15,151,518 share of common stock (or Pre-Funded Warrants in lieu thereof). Pursuant to the Second Closing, upon the satisfaction (or waiver) of specified clinical development milestones and volume weighted average share price levels and trading volume conditions set forth in the Securities Purchase Agreement, we are required to issue an aggregate of 20,202,024 shares of common stock (or Pre-Funded Warrants in lieu thereof) to the Purchasers, subject to customary adjustments. Pursuant to the Third Closing, upon the satisfaction (or waiver) of specified clinical development milestones and volume weighted average share price levels and trading volume conditions set forth in the Securities Purchase Agreement, we are required to issue an aggregate of 25,252,530 shares of common stock (or Pre-Funded Warrants in lieu thereof) to the Purchasers, subject to customary adjustments.

 In December 2023, we amended the performance-based vesting requirements with our named executive officers and other employees that upon the Second Closing and Third Closing, a full or prorated amount of each closing installment shall vest based on the percentage of funding received relative to the total funding opportunity represented by the Purchasers' Second Closing and Third Closing subscription amounts. The December amendments had the practical effect of making the vesting conditions more difficult to achieve. No specified clinical development milestones were achieved during the year ended December 31, 2023.

 Other Compensation

 Our named executive officers are eligible to participate, on the same basis as our other employees, in our employee benefit plans, including our medical, dental, vision, life and disability plans, and our 401(k) plan. We generally do not provide our named executive officers with perquisites or other personal benefits.

 401(k) Plan

 We maintain a 401(k) plan for our employees. Our named executive officers are eligible to participate in the 401(k) plan on the same basis as our other employees. The 401(k) plan is intended to qualify as a tax-qualified plan under Section 401(k) of the Internal Revenue Code of 1986, as amended (the "Code").

 The 401(k) plan provides that each participant may contribute up to the lesser of 100% of his or her compensation or the statutory limit, which was $22,500 for calendar year 2023. Participants that are 50 years or older can also make "catch-up" contributions, which in calendar year 2023 was up to an additional $7,500 above the statutory limit. We make matching contributions into the 401(k) plan on behalf of participants, matching 100% of participant contributions up to 6% of eligible compensation. Matching contributions vest immediately.

 Agreements with Named Executive Officers

 Employment Agreements

 Each of our executive officers has an employment agreement that provides severance benefits in the event of certain qualifying terminations of employment, subject to the executive's execution of a waiver and release of claims in favor of the Company and the existence of a proprietary information and inventions agreement between the executive and the Company.

 Employment Agreement with Dr. Gros

 We entered into an employment agreement with Dr. Gros on September 9, 2020, or the Gros employment agreement, under which Dr. Gros serves as our Chief Executive Officer. The Gros employment agreement provides that Dr. Gros is an at-will employee, sets forth his initial base salary of $500,000, and his eligibility to participate in employee benefit plans and programs generally available to other senior executives, as in effect from time to time. Under the Gros employment agreement, Dr. Gros is entitled to participate in our annual incentive plan described above, under which Dr. Gros's target annual incentive bonus is 60% of his annual base salary, subject to achievement of key performance indicators as determined by our Board in consultation with Dr. Gros.

 Subject to the satisfaction of certain performance-related goals set forth in his employment agreement, Dr. Gros will be eligible to receive a performance bonus in the amount of $10,000,000, payable at the election of the Company in cash, common stock or in a combination of cash and common stock. As described in more detail below, Dr. Gros is also eligible to receive a grant of additional shares of common stock (which may be satisfied with a payment in cash in lieu of stock) that in the aggregate shall be equal to one percent of the total number of shares of common stock on a fully-diluted basis, subject to terms and conditions set forth in his employment agreement, as amended and described below.

 Pursuant to the terms of the Gros employment agreement, if Dr. Gros's employment is terminated for cause (as defined in his employment agreement) or by Dr. Gros without good reason (as defined in his employment agreement), Dr. Gros will receive (i) his base salary accrued through the date of termination, (ii) unpaid expense reimbursements, and (iii) any vested benefits under the employee benefit plans of the Company (the "vested compensation"). Pursuant to the terms of the Gros employment agreement, if Dr. Gros's employment is terminated by the Company without cause (as defined in his employment agreement) or by Dr. Gros for good reason (as defined in his employment agreement), Dr. Gros will receive the vested compensation, and, subject to Dr. Gros's execution of a release in favor of the Company, Dr. Gros will be entitled to receive: (i) an amount equal to twelve months of base salary, (ii) a pro rata portion of Dr. Gros's annual target bonus for the year in which termination of service occurs, (iii) credit for an additional twelve months of vesting under all outstanding equity awards that are subject to time-based vesting criteria, and (iv) up to 12 months of health insurance reimbursement under COBRA. In the event that Dr. Gros' employment is terminated without cause or for good reason within 90 days before or twelve months after a change in control of the Company (as defined in his employment agreement), in lieu of the severance payments and benefits described in the preceding sentences and subject to Dr. Gros' execution of a release in favor of the Company, Dr. Gros will be entitled to receive, in addition to the vested rights: (i) an amount equal to 1.5 times his annual base salary and annual target bonus, (ii) full acceleration of vesting of all equity awards subject to time-based vesting criteria, and (iii) up to 18 months of health insurance reimbursement under COBRA.

 On April 27, 2023, we entered into a letter agreement with Dr. Gros that amends his current employment agreement. Pursuant to the letter agreement, Dr. Gros remains entitled to a $10,000,000 performance bonus; however, the letter agreement entitles Dr. Gros to a pro-rata portion of his performance bonus in the event that his employment is terminated for any reason other than by the Company for cause and our market value at the time of termination of employment is equal to or greater than $600 million, but less than $1 billion. The threshold performance bonus payment is $6,000,000 at a $600 million market value and increases up to the maximum $10,000,000 bonus payable at a $1 billion market value using linear interpolation. The amendment also provides that market value is calculated by taking into account the total value of all securities treated as equity securities in the Company's financial statements ("Market Value").

 In addition, the amendment provides for a retention bonus upon the earlier to occur of (i) a termination of his employment other than for cause, (ii) a change in control of the Company during the term of his employment, and (iii) July 31, 2026 (the earliest date to be the "Retention Bonus Date"). The retention bonus will be paid in cash or stock in an amount equal to the product of 761,589 multiplied by the difference between the fair market value of our common stock on the

 Retention Bonus Date over the fair market value of our common stock at the time of the Initial Closing of the Private Placement. The common stock price used to calculate the retention bonus, however, will be limited to a maximum of $9.00.

 The amendment also provides for vesting acceleration of Dr. Gros' outstanding equity awards. If Dr. Gros' employment is terminated by the Company without cause or by him for good reason, subject to his execution of the release contemplated by his employment agreement, any then-unvested and outstanding performance-based equity awards will now (1) remain outstanding and eligible to vest if the applicable performance conditions are satisfied during the 12 months following such termination of employment, and (2) the term of such performance-based options will be extended until the earlier of (A) 90 days after the performance conditions are achieved and (B) the normal expiration date of such performance-based options. If Dr. Gros' employment is terminated without cause or for good reason in connection with a change in control of the Company, subject to his execution of the release contemplated by his employment agreement, any then-unvested and outstanding performance-based equity awards will become fully vested at the target performance level.

 Finally, the letter agreement modifies Dr. Gros' rights to receive a grant of additional shares equal to one percent of the total number of shares of common stock on a fully-diluted basis. Dr. Gros will be eligible to receive a proportionate grant of common stock that will be equal to one percent of the fully diluted shares of common stock, upon the first occurrence of (i) the exercise of a majority of the Tranche C Warrants or Pre-Funded Warrants held by the largest holder of such warrants on the initial closing of the Private Placement and (ii) the first date that is six months after the date on which topline data for the Company's kidney transplantation phase 2 trial (K207) is available to the Company and where the Company's Market Value is equal to or greater than $900 million for a period of 20 consecutive calendar days. Dr. Gros will be entitled to such new incentive shares if either of the above conditions are satisfied at any time during the term of his employment agreement or within 12 months following a termination of his employment without cause or for good reason.

 Employment Agreement with Dr. Perrin

 We entered into an employment agreement with Dr. Perrin on September 14, 2020, or the Perrin employment agreement, under which Dr. Perrin serves as our President and Chief Scientific Officer. The Perrin employment agreement provides that Dr. Perrin is an at-will employee, sets forth his initial base salary of $400,000, and his eligibility to participate in employee benefit plans and programs generally available to other senior executives, as in effect from time to time. Dr. Perrin is entitled to participate in our annual incentive plan described above, under which Dr. Perrin's target annual incentive bonus is 50% of his annual base salary, subject to achievement of key performance indicators as determined by our Board in consultation with Dr. Perrin.

 Pursuant to the terms of the Perrin employment agreement, if Dr. Perrin's employment is terminated for cause (as defined in his employment agreement) or by Dr. Perrin without good reason (as defined in his employment agreement), Dr. Perrin will receive (i) his base salary accrued through the date of termination, (ii) unpaid expense reimbursements, and (iii) any vested benefits under the employee benefit plans of the Company (the "vested compensation"). Pursuant to the terms of his employment agreement, if Dr. Perrin's employment is terminated by the Company without cause (as defined in his employment agreement) or by Dr. Perrin for good reason (as defined in his employment agreement), Dr. Perrin will receive the vested compensation. Additionally, subject to Dr. Perrin's execution of a release in favor of the Company, Dr. Perrin will be entitled to receive either: (i) an amount equal to 1.5 times his base salary payable over eighteen months if Dr. Perrin's employment is terminated before the first anniversary of the effective date of the employment agreement, or (ii) an amount equal to 1.0 times his base salary payable over twelve months if Dr. Perrin's employment is terminated after the first anniversary of the effective date of the employment agreement. Dr. Perrin will also be entitled to receive (i) acceleration of vesting of the equity awards initially granted to him under his employment agreement, and (ii) up to 12 months of health insurance reimbursement under COBRA. In the event that Dr. Perrin's employment is terminated without cause, or Dr. Perrin terminates his employment for good reason, in either case within 30 days before or twelve months after a change in control, in lieu of the severance payments and benefits described in the preceding sentences and subject to Dr. Perrin's execution of a release in favor of the Company, Dr. Perrin will be entitled to receive the vested compensation, as well as: (i) an amount equal to 1.0 times his base salary and annual target bonus for the year in which termination occurs, (ii) full acceleration of all equity awards subject to time-based vesting, and (iii) up to 18 months of health insurance reimbursement under COBRA.

 On April 27, 2023, we entered into a letter agreement with Dr. Perrin amending his employment agreement. Dr. Perrin's employment agreement amendment provides for a retention bonus upon the earlier to occur of (i) a termination of his employment other than for cause, (ii) a change in control of the Company during the term of his employment, and (iii) July 31, 2026 (the earliest date to be the "Retention Bonus Date"). The retention bonus will be paid in cash or stock in an amount equal to the product of 327,350 multiplied by the difference between the fair market value of our common stock on the Retention Bonus Date over the fair market value of our common stock at the time of the Initial Closing of the Private Placement. The common stock price used to calculate the retention bonus, however, will be limited to a maximum of $9.00.

 Employment Agreement with Mr. Little

 We entered into an employment agreement with Mr. Little on March 15, 2021, or the Little employment agreement, under which Mr. Little serves as our Chief Financial Officer. The Little employment agreement provides that Mr. Little is an at-will employee, sets forth his initial base salary of $410,000, and his eligibility to participate in employee benefit plans and programs generally available to other senior executives, as in effect from time to time. Mr. Little is entitled to participate in our annual incentive plan described above, under which Mr. Little's target annual incentive bonus is 40% of his annual base salary, subject to achievement of key performance indicators as determined by our Board in consultation with Mr. Little.

 Pursuant to the terms of the Little employment agreement, if Mr. Little's employment is terminated for cause (as defined in his employment agreement) or by Mr. Little without good reason (as defined in his employment agreement), Mr. Little will receive (i) his base salary accrued through the date of termination, (ii) unpaid expense reimbursements, and (iii) any vested benefits under the employee benefit plans of the Company (the "vested compensation"). Pursuant to the terms of his employment agreement, if Mr. Little's employment is terminated by the Company without cause (as defined in his employment agreement) or by Mr. Little for good reason (as defined in his employment agreement), Mr. Little will receive the vested compensation. Additionally, subject to Mr. Little's execution of a release in favor of the Company, Mr. Little will be entitled to receive (i) an amount equal to 9 months of his base salary, payable over 9 months, (ii) accelerated vesting of the portion of all outstanding equity awards subject to time-based vesting that would have vested and become exercisable during the 9-month period following Mr. Little's termination of employment, and (iii) up to 9 months of health insurance reimbursement under COBRA. In the event Mr. Little's employment is terminated by the Company without cause (other than by reason of death or disability) or if Mr. Little resigns for good reason, in either event in connection with a change in control, Mr. Little shall be entitled to receive in lieu of the benefits described in the preceding sentences, and subject to Mr. Little's execution of a release in favor of the Company, the vested compensation, as well as: (i) an amount equal to 1.0 times his base salary and annual target bonus for the year in which termination occurs, (ii) full acceleration of all equity awards subject to time-based vesting, (iii) payment equal to the greater of either Mr. Little's annual target incentive bonus for the year in which the termination occurs or the annual target incentive bonus paid to Mr. Little with respect to the calendar year immediately preceding the calendar year during which the termination occurs, payable in a single lump sum, and (iv) up to 12 months of health insurance reimbursement under COBRA.

 DIRECTOR COMPENSATION

 2023 Non-Employee Director Compensation Policy

 Our Board has approved a compensation policy for our non-employee directors that is designed to provide a total compensation package that enables us to attract and retain qualified and experienced individuals to serve as directors and to align our directors' interests with those of our stockholders.

 Under our non-employee director compensation policy, we pay each of our non-employee directors a cash retainer for service on the Board and for service on each committee on which the director is a member. The Board Chair and chair of each committee receives an additional retainer for such service. These retainers are payable in arrears in four equal quarterly installments on the last day of each quarter, provided that the amount of such payment will be prorated for any portion of such quarter that the director is not serving on our Board.

 Cash Compensation

 Based on a review of compensation practices, the Board has approved the following compensation for non-employee directors:

 Equity Compensation

 Our non-employee director compensation plan provides for (i) an initial equity grant of 150,437 stock options, which vest ratably over two years, subject to the director's continued service on our Board, and (ii) annual equity grants of 20,000 stock options, which vest after one year, subject to the director's continued service as a director.

 In 2023, annual equity grants of 20,000 stock options were issued to each non-employee director of our Board.

 In May 2023, we issued additional stock option awards to our then serving non-employee directors in connection with our entry into the Securities Purchase Agreement described above. These additional stock option grants have a two-year vesting schedule (as opposed to our normal annual grant vesting schedule of one-year), and were issued as additional compensation in light of the consummation of the transactions contemplated by the Securities Purchase Agreement.

 Expense Reimbursement

 Directors have been and will continue to be reimbursed for expenses directly related to their activities as directors, including attendance at Board and committee meetings.

 Fiscal Year 2023 Director Compensation Table

 The compensation provided to our non-employee directors in 2023 is enumerated in the table below. The table excludes David-Alexandre C. Gros, M.D., our Chief Executive Officer, and Steve Perrin, Ph. D, our President and Chief Scientific Officer, both of whom served as executive officers in 2023. Neither Dr. Gros nor Dr. Perrin received any compensation for serving as a director in 2023.

 (1) The dollar amounts in this column represent the grant date fair value of the stock options granted during 2023. These amounts have been calculated in accordance with Financial Accounting Standards Board ("FASB") ASC 718, Compensation – Stock Compensation, and, with respect to stock options, using the Black-Scholes option-pricing model. For a discussion of valuation assumptions, see Note 11 to the consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2023 regarding assumptions underlying the valuation of equity awards. These amounts do not necessarily correspond to the actual value that may be recognized from the stock options by the applicable directors. Amounts reported include the value of the May 2023 grants described above that were made in connection with the transactions entered into under the Securities Purchase Agreement.

 (2) As of December 31, 2023, each non-employee director held the following number of outstanding and unexercised options: Mr. Katkin 1,124,272 options, Dr. Hillson 230,437 options, Dr. Kirk 150,437 options, Dr. Lee 230,437 options, Mr. Lyons 257,898, Mr. McBride 259,742 options, Mr. Ogier 438,221 options and Mr. Robinson 150,437 options.

 SECURITIES AUTHORIZED FOR ISSUANCE UNDER EQUITY COMPENSATION PLANS

 The following table contains information about our equity compensation plans as of December 31, 2023. As of December 31, 2023, we had four equity compensation plans, each of which was approved by our stockholders: our 2007 Stock Incentive Plan or 2007 Plan, our 2014 Stock Incentive Plan, or 2014 Plan, our 2020 Incentive Plan or 2020 Plan, and our 2014 Employee Stock Purchase Plan, or 2014 ESPP. The Company intends for the 2020 Plan to be its primary stock compensation plan in the future. The 2014 Plan was closed to new grants following the approval of the 2020 Plan, and therefore, there were no shares reserved for issuance under the 2007 and 2014 Plan as of December 31, 2023.

 SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

 Unless otherwise provided below, the following table sets forth information regarding beneficial ownership of our common stock as of March 31, 2024 by:

 • each person, or group of affiliated persons, known to us to be the beneficial owner of more than 5% of the outstanding shares of our common stock;

 • each of our current directors;

 • our named executive officers; and

 • all of our executive officers and directors as a group.

 Beneficial ownership is determined in accordance with the rules and regulations of the SEC and includes voting or investment power with respect to our common stock. Shares of our common stock subject to options, restricted stock unit awards or warrants that are currently exercisable or will become exercisable within 60 days after March 31, 2024 are considered outstanding and beneficially owned by the person holding the options, restricted stock units or warrants for the purpose of calculating the percentage ownership of that person, but not for the purpose of calculating the percentage ownership of any other person. Except as otherwise noted, to our knowledge, the persons and entities in this table have sole

 voting and investing power with respect to all of the shares of our common stock beneficially owned by them, subject to applicable community property laws. The inclusion herein of any shares as beneficially owned does not constitute an admission of beneficial ownership.

 The column entitled "Percentage of Shares Beneficially Owned" is based on a total of 24,813,130 shares of our common stock outstanding as of March 31, 2024. Beneficial ownership representing less than one percent of our outstanding common stock is denoted with an "*."

 Item 13. Certain Relationships and Related Transactions, and Director Independence.

 CERTAIN RELATIONSHIPS AND RELATED PERSON TRANSACTIONS

 Policies and Procedures for Related Person Transactions

 Our Board has adopted a written related person transaction policy to set forth policies and procedures for the review and approval or ratification of related person transactions. This policy covers any transaction, arrangement or relationship, or any series of similar transactions, arrangements or relationships, in which we were or are to be a participant, the amount involved exceeds the lesser of $120,000 or one percent of the average of the our total assets at year-end for the last two completed fiscal years, and a related person had or will have a direct or indirect material interest, including, without limitation, purchases of goods or services by or from the related person or entities in which the related person has a material interest, indebtedness, guarantees of indebtedness and employment by us of a related person.

 Our related person transaction policy contains exceptions for any transaction or interest that is not considered a related person transaction under SEC rules as in effect from time to time. In addition, the policy provides that an interest arising solely from a related person's position as an executive officer of another entity that is a participant in a transaction with us will not be subject to the policy if each of the following conditions is met:

 • the related person and all other related persons own in the aggregate less than a 10% equity interest in such entity;

 • the related person and his or her immediate family members are not involved in the negotiation of the terms of the transaction with us and do not receive any special benefits as a result of the transaction; and

 • the amount involved in the transaction is less than the greater of $200,000 and 5% of the annual gross revenue of the company receiving payment under the transaction.

 The policy provides that any related person transaction proposed to be entered into by us must be reported to our Chief Executive Officer or Chief Financial Officer and will be reviewed and approved by our audit committee in accordance with the terms of the policy, prior to effectiveness or consummation of the transaction whenever practicable. The policy provides that if our Chief Executive Officer or Chief Financial Officer determines that advance approval of a related person transaction is not practicable under the circumstances, our audit committee will review and, in its discretion, may ratify the related person transaction at the next meeting of the audit committee. The policy also provides that alternatively, our Chief Executive Officer or Chief Financial Officer may present a related person transaction arising in the time period between meetings of the audit committee to the chair of the audit committee, who will review and may approve the related person transaction, subject to ratification by the audit committee at the next meeting of the audit committee.

 In addition, the policy provides that any related person transaction previously approved by the audit committee or otherwise already existing that is ongoing in nature will be reviewed by the audit committee annually to ensure that such related person transaction has been conducted in accordance with the previous approval granted by the audit committee, if any, and that all required disclosures regarding the related person transaction are made.

 The policy provides that transactions involving compensation of executive officers will be reviewed and approved by our compensation committee in the manner to be specified in the charter of the compensation committee.

 A related person transaction reviewed under this policy will be considered approved or ratified if it is authorized by the audit committee in accordance with the standards set forth in the policy after full disclosure of the related person's interests in the transaction. As appropriate for the circumstances, the policy provides that the audit committee will review and consider:

 • the related person's interest in the related person transaction;

 • the approximate dollar value of the amount involved in the related person transaction;

 • the approximate dollar value of the amount of the related person's interest in the transaction without regard to the amount of any profit or loss;

 • whether the transaction was undertaken in the ordinary course of business of our company;

 • whether the transaction with the related person is proposed to be, or was, entered into on terms no less favorable to us than the terms that could have been reached with an unrelated third party;

 • the purpose of, and the potential benefits to us of, the transaction; and

 • any other information regarding the related person transaction or the related person in the context of the proposed transaction that would be material to investors in light of the circumstances of the particular transaction.

 The policy provides that the audit committee will review all relevant information available to it about the related person transaction. The policy provides that the audit committee may approve or ratify the related person transaction only if the audit committee determines that, under all of the circumstances, the transaction is in, or is not inconsistent with, our best interests. The policy provides that the audit committee may, in its sole discretion, impose such conditions as it deems appropriate on us or the related person in connection with approval of the related person transaction.

 Related Person Transactions

 We have not been a party to any transaction since January 1, 2022 in which the amounts involved exceeded or will exceed the lesser of $120,000 or one percent of the average of our total assets at year-end for the last two years, and in which any of our directors, executive officers, nominees for director or holders of more than 5% of our capital stock, or any member of the immediate family of, or person sharing the household with, the foregoing persons, had or will have a direct or indirect material interest that is reportable pursuant to Item 404(a) of Regulation S-K.

 DIRECTOR INDEPENDENCE

 Rule 5605 of the Nasdaq Listing Rules requires a majority of a listed company's board of directors to be comprised of independent directors. In addition, the Nasdaq Listing Rules require that, subject to specified exceptions, each member of a listed company's audit, compensation and nominating and corporate governance committees be independent under the Exchange Act. Audit committee members must also satisfy the independence criteria set forth in Rule 10A-3 under the Exchange Act, and compensation committee members must also satisfy the independence criteria set forth in Rule 5605(d)(2) of the Nasdaq Listing Rules. Under Rule 5605(a)(2) of the Nasdaq Listing Rules, a director will only qualify as an "independent director" if, in the opinion of our Board, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. In order to be considered independent for purposes of Rule 10A-3 under the Exchange Act, a member of an audit committee of a listed company may not, other than in his or her capacity as a member of the audit committee, the board of directors, or any other board committee, accept, directly or indirectly, any consulting, advisory, or other compensatory fee from the listed company or any of its subsidiaries or otherwise be an affiliated person of the listed company or any of its subsidiaries. In order to be considered independent for purposes of Rule 5605(d)(2) of the Nasdaq Listing Rules, the board must consider, for each member of a compensation committee of a listed company, all factors specifically relevant to determining whether a director has a relationship to such company which is material to that director's ability to be independent from management in connection with the duties of a

 compensation committee member, including, but not limited to: (1) the source of compensation of the director, including any consulting advisory or other compensatory fee paid by such company to the director; and (2) whether the director is affiliated with the company or any of its subsidiaries or affiliates.

 Our Board undertook a review of the composition of our Board and its committees and the independence of each director. Based upon information requested from and provided by each director concerning his or her background, employment and affiliations, including family relationships, our Board has determined that each of Drs. Lee, Hillson and Kirk and Messrs. Ogier, Katkin, McBride and Robinson is an "independent director" as defined under Rule 5605(a)(2) of the Nasdaq Listing Rules). The Board also determined that Gary L. Lyons, who retired from our Board in June 2023, was an "independent director" as defined under Rule 5605(a)(2) of the Nasdaq Listing Rules during his service in 2023. Dr. Gros is not an independent director under Rule 5605(a)(2) because he is our Chief Executive Officer. Dr. Perrin is not an independent director under Rule 5605(a)(2) because he is our President and Chief Scientific Officer.

 Our Board also determined that John S. McBride, James Robinson and Walter Ogier who currently serve on our audit committee, satisfy the independence standards for audit committees established by the SEC and the Nasdaq Listing Rules, including the independence requirements contemplated by Rule 10A-3 under the Exchange Act. In addition, our Board determined that June Lee, Walter Ogier and James Robinson, who currently serve on our compensation committee, satisfy the enhanced independence standards for compensation committees established by Rule 5605(d)(2) of the Nasdaq Listing Rules. In making such determinations, our Board considered the relationships that each such non-employee director has with our company and all other facts and circumstances our Board deemed relevant in determining independence, including the beneficial ownership of our capital stock by each non-employee director.

 Item 14. Principal Accountant Fees and Services.

 Audit Fees and Services

 KMJ Corbin & Company LLP ("KMJ") was our independent registered public firm for the years ended 2023 and 2022. The following table summarizes the fees KMJ billed to us for each of the last two fiscal years. All of such services and fees were pre-approved by our audit committee in accordance with the "Pre-Approval Policies and Procedures" described below.

 (1) Audit fees consist of fees for the audit of our annual financial statements, the review of the interim financial statements and other services provided in connection with regulatory filings or engagements.

 POLICY ON PRE-APPROVAL OF AUDIT AND PERMISSIBLE NON-AUDIT SERVICES

 Our audit committee has adopted procedures requiring the pre-approval of all audit and non-audit services performed by our independent registered public accounting firm in order to assure that these services do not impair the auditor's independence. These procedures generally approve the performance of specific services subject to a cost limit for all such services. This general approval is to be reviewed, and if necessary modified, at least annually. Management must obtain the specific prior approval of the audit committee for each engagement of the independent registered public accounting firm to perform other audit-related or other non-audit services. The audit committee does not delegate its responsibility to approve services performed by the independent registered public accounting firm to any member of management. Our audit committee has delegated authority to the committee chair to pre-approve any audit or non-audit service to be provided to us by our independent registered public accounting firm provided that the fees for such services do not exceed $50,000. Any approval of services by the committee chair pursuant to this delegated authority must be reported to the audit committee at the next meeting of the committee.

 The standard applied by the audit committee, or the chair of the audit committee, in determining whether to grant approval of any type of non-audit service, or of any specific engagement to perform a non-audit service, is whether the services to be performed, the compensation to be paid therefore and other related factors are consistent with the independent registered public accounting firm's independence under guidelines of the SEC and applicable professional standards. Relevant considerations include whether the work product is likely to be subject to, or implicated in, audit procedures during the audit of our financial statements, whether the independent registered public accounting firm would be functioning in the role of management or in an advocacy role, whether the independent registered public accounting firm's performance of the service would enhance our ability to manage or control risk or improve audit quality, whether such performance would increase efficiency because of the independent registered public accounting firm's familiarity with our business, personnel, culture, systems, risk profile and other factors, and whether the amount of fees involved, or the non-audit services portion of the total fees payable to the independent registered public accounting firm in the period would tend to reduce the independent registered public accounting firm's ability to exercise independent judgment in performing the audit.
