 Todd Schonherz has over 30 years of healthcare experience and has served as our Chief Executive Officer since the closing of the Business Combination in September 2023. Mr. Schonherz has served as the Chief Executive Officer of American Oncology Network, LLC ("AON LLC") since 2021 and was previously President & Chief Operating Officer of AON LLC since its inception in 2017 to 2021. Previously, he was Chief Operating Officer of Florida Cancer Specialists ("FCS"). Prior to his role as COO of FCS in 2011, Mr. Schonherz was Senior Vice President and Chief Information Officer for US Oncology from 1999 to 2010. Mr. Schonherz' consulting and management experience in healthcare information technology includes positions with Datamedic Corporation (acquired by VitalWorks and later Amicas Corporation), Multum Corporation (acquired by Cerner Corporation), and MedE America (acquired by WebMD and later HLTH Corporation). Mr. Schonherz received a bachelor's degree in health policy and administration from Pennsylvania State University. Mr. Schonherz has presented at national industry conferences including multiple Community Oncology Alliance ("COA") conferences as well as national and regional information technology conferences. We believe Mr. Schonherz's 30 years of healthcare experience gives him a thorough understanding of all aspects of our business and operations and qualifies him to serve our Board of Directors.

 David H. Gould has served as our Chief Financial Officer since the closing of the Business Combination in September 2023 and has served as Chief Financial Officer at AON LLC since September 2020. Prior to joining AON LLC, David was employed at ApolloMD from March 2016 through September 2020, including serving as its Chief Financial Officer from February 2018 to September 2020. Prior to joining ApolloMD, David served approximately 10 years in progressively senior positions and ultimately as the Vice President of Finance and Assistant Treasurer at Cumulus Media. Prior to that, he held financial management roles with both publicly traded and private companies within the healthcare industry. David started his career in public accounting with the national audit firm of Ernst & Young out of their Washington, D.C. office. David holds a Bachelor of Science in Accounting from University of Maryland.

 Stephen "Fred" Divers, MD has served as our Chief Medical Officer since the closing of the Business Combination in September 2023 and has been AON LLC's Chief Medical Officer since 2022.

He attended medical school at the Louisiana State University School of Medicine. He completed his residency at the University of North Carolina and a fellowship at the University of Alabama at Birmingham Cancer Center. We believe that Dr. Diver's experience as an executive and his breadth of knowledge and valuable understanding of oncology care qualifies him to serve on our Board of Directors.

 Erica Mallon is a healthcare-specialized attorney with nearly a decade of transactional and regulatory experience and has served as AON's General Counsel since the closing of the Business Combination in September 2023. Ms. Mallon has served as AON LLC's General Counsel since May 2021.

Mr. Fluegel also serves as a lecturer at the University of Pennsylvania's Wharton School of Business. We believe Mr. Fluegel's public company experience and expertise in accounting matters is valuable to the Company.

Mr. Sarin also previously served on the board of directors of The Oncology Institute. Mr. Sarin received a B.S. in Electrical Engineering and a M.S. in Management Science & Engineering from Stanford University and an M.B.A. from Harvard Business School. Mr. Sarin was selected to serve on our Board of Directors due to his experience working with and serving as a director of a number of healthcare services companies.

 James Stith has served on our Board of Directors since the closing of the Business Combination in September 2023, and has served as a Director on AON LLC's Board of Managers since June 2023.

Mr. Stith holds a B.A. in Economics and International Relations from the University of Pennsylvania. We believe Mr. Stith's extensive experience in growth equity and healthcare investing qualifies him to serve on our Board of Directors.

 William J. Valle has served on our Board of Directors since April 19, 2024. Mr. Valle served as Chief Executive Officer and a board member of Fresenius Medical Care, a leading provider of dialysis products and comprehensive chronic kidney disease care, from 2017 to 2023. Mr. Valle was also previously the President and Chief Executive Officer of Strategic Advisory Services at Innovative Health Strategies, LLC. Mr. Valle has also served on the board of directors of multiple healthcare companies, including Interwell Health and Sound Physicians. We believe Mr. Valle's experience as a board member for multiple healthcare companies and as a healthcare executive qualifies him to serve on our Board of Directors and is valuable to the Company.

 Family Relationships

 There are no family relationships between any director, executive officer, or person nominated or chosen to be a director or officer.

 Code of Ethics

 The Board has adopted a Code of Conduct and Ethics that applies to all of its employees, officers and directors, including its principal executive officer, principal financial officer, controller and other executive and senior financial officers. The full text of AON's Code of Conduct and Ethics is posted on the Corporate Governance portion of AON's website. When applicable, AON will post amendments to its Code of Business Conduct and Ethics or waivers of its Code of Business Conduct and Ethics for directors and officers on the same website.

 Clawback Policy

 The SEC adopted final rules implementing the incentive-based compensation recovery provisions of the Dodd-Frank Act, and the Nasdaq Stock Market LLC ("Nasdaq") has adopted listing standards consistent with the SEC rules. In compliance with those standards, we have adopted an incentive compensation recoupment policy, or "clawback" policy, which applies to our executive officers, within the meaning of Section 10D of the Exchange Act and Rule 10D-1 promulgated thereunder, who were employed by the Company during the applicable recovery period. Under the policy, in the event that the financial results upon which a cash or equity-based incentive award was predicated become the subject of a financial restatement that is required because of material non-compliance with financial reporting requirements, the Compensation Committee will conduct a review of awards covered by the policy and recoup any erroneously awarded incentive-based compensation to ensure that the ultimate payout gives retroactive effect to the financial results as restated. The Company may not indemnify any such covered officer against the loss of such recovered compensation. Our clawback policy is filed in this Annual Report on Form 10-K as Exhibit 97.

 Board Composition

 AON's business and affairs are managed under the direction of its Board.

 The AON Board is divided into three classes, designated as Class I, Class II and Class III. The directors first elected to Class I will hold office for a term expiring at the first annual meeting of stockholders following the consummation of the Business Combination; the directors first elected to Class II will hold office for a term expiring at the second annual meeting of stockholders following the consummation of the Business Combination; and the directors first elected to Class III will hold office for a term expiring at the third annual meeting of stockholders following the consummation of the Business Combination. At each succeeding annual meeting of the stockholders of AON, the successors to the class of directors whose term expires at that meeting will be elected by plurality vote of all votes cast at such meeting to hold office for a term expiring at the annual meeting of stockholders held in the third year following the year of their election.

 Currently, there are two Class II director vacancies.

 The AON Board has extensive involvement in the oversight of risk management related to AON and its business as a whole, including its strategy, business performance, capital structure, management selection, compensation programs, shareholder engagement, corporate reputation, ESG matters, and ethical business practices. The AON Board will discharge various aspects of its oversight responsibilities through its standing committees, which in turn will report to it regularly regarding their activities. The Audit Committee will represent the AON Board by periodically reviewing our accounting, reporting and financial practices, including the integrity of AON's financial statements and the surveillance of administrative and financial controls, as well as enterprise risk management, cyber risk and review of related party transactions.

 Through its regular meetings with management, including the finance, legal, internal audit and information technology functions, the audit committee will review and discuss all significant areas of our business and summarize for the AON Board all areas of risk and the appropriate mitigating factors. The governance committee will provide oversight over compliance with legal and regulatory requirements, ethics and whistleblower matters. The Compensation Committee will review the Company's incentive compensation arrangements to determine whether they encourage excessive risk-taking and discuss with management the relationship between risk management policies and practices and compensation.

In addition, the AON Board will receive periodic detailed operating performance reviews from management.

 Narrative Disclosure to Summary Compensation Table

 The following describes the material elements of our compensation program for the fiscal year ended December 31, 2023 as applicable to our NEOs and reflected in the Summary Compensation Table above.

 Base Salary

 Base salaries for our executive officers were established primarily based on individual negotiations with the executive officers when they joined us. In determining compensation for our executive officers, we considered salaries provided to executive officers of similarly situated companies in the healthcare industry, each executive officer's anticipated role criticality relative to others at the Company and our determination of the essential need to attract and retain these executive officers.

 Employee Benefits and Perquisites

 We provide health, dental, vision, life and disability insurance benefits to our NEOs, on the same terms and conditions as provided to our other employees. We provide an automobile allowance to select executive officers as well as small incidental reimbursements for certain personal expenses such as travel costs and mobile devices.

 Retirement Benefits

 401(k) Plan. We maintain a 401(k) plan that provides eligible U.S. employees with an opportunity to save for retirement on a tax advantaged basis. Eligible employees are able to defer eligible compensation up to certain Internal Revenue Code (the "Code") limits, which are updated annually. Contributions are allocated to each participant's individual account and are then invested in selected investment alternatives according to the participants' directions.
 Employees are immediately and fully vested in their own contributions. The Company may elect to make matching or other contributions into participant's individual accounts. The 401(k) plan is intended to be qualified under Section 401(a) of the Code, with the related trust intended to be tax exempt under Section 501(a) of the Code. As a tax-qualified retirement plan, contributions to the 401(k) plan are deductible by us when made, and contributions and earnings on those amounts are not taxable to the employees until withdrawn or distributed from the 401(k) plan.

 Employment Agreements

 On April 1, 2021, we entered into an employment agreement with Mr. Schonherz (the "Schonherz Employment Agreement"), pursuant to which he agreed to serve as our Chief Executive Officer. The Schonherz Employment Agreement has an initial term through March 31, 2026 and automatically renews for one-year periods thereafter, unless terminated in advance by either party in accordance with the terms of the agreement. Pursuant to the Schonherz Employment Agreement, Mr. Schonherz is entitled to receive an annual base salary of $675,000 per year (the "Base Salary"). Mr. Schonherz's Base Salary is increased on an annual basis in the amount of three percent of the previous calendar year's Base Salary on January 1 of each year during the term and any renewal term under the Schonherz Employment Agreement.
 The Schonherz Employment Agreement also provides that Mr. Schonherz is eligible for an annual cash bonus based upon achievement of annual performance goals for Mr. Schonherz and/or the Company determined by the Board each year. Mr. Schonherz's annual fully-earned bonus opportunity is equal to a minimum of $275,000 for 2021 and will be determined by the Board for subsequent years.

 We do not have an employment agreement with Dr. Divers in connection with employment as Chief Medical Officer.

 On July 28, 2020, we entered into an offer letter with David Gould, pursuant to which he agreed to serve as our Chief Financial Officer with a start date of September 17, 2020 (the "Gould Offer Letter"). Under the Gould Offer Letter, Mr. Gould is eligible for a base salary of $300,000. The Gould Offer Letter also provides that Mr. Gould is eligible for an annual salary increase and an annual cash bonus based upon achievement of annual performance goals for Mr. Gould and/or the Company of up to 20% of Mr. Gould's base salary, with a stretch opportunity up to 25% of Mr. Gould's base salary.

 Outstanding Equity Awards at Fiscal Year-End 2023

 There were no outstanding equity awards held by the NEOs at December 31, 2023.

 Potential Payments Upon Termination or Change in Control

 Todd Schonherz
 Under the terms of his employment agreement, if Mr. Schonherz's employment is terminated by AON without cause or by Mr. Schonherz for good reason (as such terms are defined in the Schonherz Employment Agreement), then Mr. Schonherz will become eligible to receive the following benefits for a period of twelve (12) months after the effective date of his termination or until he obtains and commences other employment, whichever occurs first:

 • monthly payments equal to (a) his monthly base salary in effect immediately prior to termination, plus (b) an amount equal to one-twelfth of his performance bonus which was paid or is to be paid to him under the Schonherz Employment Agreement for prior calendar year; and

 • monthly insurance stipend payments equal to aggregate insurance premiums paid by AON to provide health, dental, vision, and disability insurance benefits for him of the effective date of termination, calculated as a monthly amount.

 Stephen "Fred" Divers

 Item 12. Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters

 The table below sets forth information regarding the beneficial ownership of AON common stock as of April 16, 2024, a recent practicable date prior to the date of this Amendment for:

 • each person known who is the beneficial owner of more than five percent (5%) of the outstanding shares of AON Class A Common Stock, Class B Common Stock and Series A Preferred Stock;
 • each member of the Board and each of AON's NEOs (including former executive officer Bradley Prechtl), who is an NEO of AON as of the end of the last fiscal year;
 • all current executive officers and directors of the Company, as a group.

 Beneficial ownership is determined according to the rules of the SEC, which generally provide that a person has beneficial ownership of a security if he, she or it possesses sole or shared voting or investment power over that security or the right to acquire such power within 60 days.

 As of April 16, 2024 there were (i) 12,430,936 shares of AON Class A Common Stock issued and outstanding, which includes 2,839,375 of the shares of AON Class A Common Stock (the "Sponsor Earnout Shares") held by Digital Transformation Sponsor LLC (the "Sponsor"), (ii) 23,725,998 shares of AON Class B Common Stock issued and outstanding, which excludes 3,000,245 Class B Warrants and (iii) 6,651,610 shares of Series A Preferred Stock issued and outstanding, which votes on an as-converted basis equal to 6,651,610 shares of Class A Common Stock.

 Unless otherwise indicated, the Company believes that all persons named below have sole voting and investment power with respect to the voting securities indicated in the table below and the corresponding footnotes as being beneficially owned by them.

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

 Related Party Policy

 AON has a formal written policy that sets forth the following policies and procedures for the review and approval or ratification of related party transactions. A "Related Party Transaction" is a transaction, arrangement or relationship in which AON or any of its subsidiaries was, is or will be a participant, the amount of which involved exceeds $120,000, and in which any related party had, has or will have a direct or indirect material interest. A "Related Party" means:

 • any person who is, or at any time during the applicable period was, one of AON's officers or one of AON's directors;
 • any person who is known by AON to be the beneficial owner of more than five percent (5%) of its voting stock;
 • any immediate family member of any of the foregoing persons, which means any child, stepchild, parent, stepparent, spouse, sibling, mother-in-law, father-in-law, daughter-in-law, son-in-law, sister-in- law or brother-in-law of a director, officer or a beneficial owner of more than five percent (5%) of its voting stock, and any person (other than a tenant or employee) sharing the household of such director, officer or beneficial owner of more than five percent (5%) of its voting stock; and
 • any firm, corporation or other entity in which any of the foregoing persons is a partner or principal or in a similar position or in which such person has a ten percent (10%) or greater beneficial ownership interest.

 AON enacted policies and procedures designed to minimize potential conflicts of interest arising from any dealings it may have with its affiliates and to provide appropriate procedures for the disclosure of any real or potential conflicts of interest

 that may exist from time to time. Specifically, pursuant to its charter, the Audit Committee has the responsibility to review related party transactions.

 Business Combination Agreement

 DTOC, AON LLC, GEF AON Holdings Corp. ("AON Class C Preferred Investor"), and DTOC Merger Sub, Inc., a direct, wholly owned subsidiary of DTOC ("Merger Sub") entered into a Business Combination Agreement (the "Business Combination Agreement"), dated as of June 14, 2023 (which further amended and restated the Business Combination Agreement entered into by DTOC and AON as of October 5, 2022, and amended and restated on January 6, 2023, and April 27, 2023), pursuant to which, among other transactions, on September 20, 2023 (the "Closing Date"), DTOC and AON undertook a series of transactions (the "Reverse Recapitalization" or the "Business Combination") resulting in the organization of the combined post-business combination company as an umbrella partnership C corporation, in which substantially all of the assets and the business of the combined company are held by AON LLC, and DTOC became a member of AON LLC. In connection with the closing of the Business Combination (the "Closing"), DTOC changed its name to "American Oncology Network, Inc.". The Business Combination was completed on September 20, 2023.

 Related Party Transactions Following the Business Combination

 Following the Business Combination, which closed on September 20, 2023, the Company did not engage in any related party transactions under the provisions of Item 404 of Regulation S-K.

 American Oncology Network

 Since January 1, 2022, AON did not engage in any related party transactions that are required to be reported under the provisions of Item 404 of Regulation S-K. Following the Business Combination, the Company did not engage in any related party transactions under the provisions of Item 404 of Regulation S-K.

 DTOC Related Party Transactions Prior to the Business Combination

 Since January 1, 2022 and prior to the closing of the Business Combination, DTOC engaged in the following related-transactions.

 Founder Shares

 On January 8, 2021, DTOC issued an aggregate of 7,187,500 shares of Class B Common Stock to the Sponsor for an aggregate purchase price of $25,000 in cash, or approximately $0.003 per share (the "Founder Shares"). The number of shares of Class B Common Stock issued was determined based on the expectation that such shares would represent 20% of the outstanding shares of common stock upon completion of the IPO. On March 9, 2021, DTOC effected a stock dividend of 0.2 shares for each share of Class B Common Stock outstanding, resulting in the Sponsor holding an aggregate of 8,625,000 shares of Class B Common Stock. The Sponsor subsequently transferred 25,000 shares of Class B Common Stock to each of DTOC's independent directors, and 150,000 shares of Class B Common Stock to Kyle Francis, DTOC's Chief Financial Officer. Up to 1,125,000 shares of Class B Common Stock were subject to forfeiture by the Sponsor depending on the extent to which the underwriter's over-allotment option was exercised. On March 12, 2021, the underwriter partially exercised its over-allotment option, hence, 837,500 shares of Class B Common Stock were no longer subject to forfeiture. On March 15, 2021, the underwriter forfeited the remaining over-allotment option, and hence 287,500 shares of Class B Common Stock were subsequently forfeited.

 On February 9, 2023, DTOC filed a definitive proxy statement with the SEC soliciting the approval of its stockholders for, among other things, a proposal (the "Extension Amendment Proposal") to extend the date by which DTOC has to consummate a business combination (the "Combination Period") from March 12, 2023 to June 30, 2023, and to give the Sponsor the option to further extend the Combination Period beyond June 30, 2023 up to three (3) times for an additional one (1) month each time to September 30, 2023. On March 7, 2023, in connection with the approval of the Extension Amendment Proposal, the Sponsor and Kyle Francis, DTOC's Chief Financial Officer, converted all of their respective Founder Shares into an aggregate of 8,262,500 shares of DTOC Class A Common Stock.

 The Sponsor and members of DTOC's board of directors and management team (collectively, the "Initial Stockholders") agreed, subject to limited exceptions, not to transfer, assign or sell any of the Founder Shares until the earlier to occur of: (1) one year after the completion of the initial business combination; and (2) subsequent to the initial business combination (x) if the last reported sale price of the Class A Common Stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any twenty (20) trading days within any thirty (30) trading day period commencing at least one hundred fifty (150) days after the initial Business Combination or (y) the date on which we complete a liquidation, merger, capital stock exchange, reorganization or other similar transaction that results in all of the public stockholders having the right to exchange their shares of common stock for cash, securities or other property.

 Private Placement Warrants

 Simultaneously with the closing of DTOC's IPO, DTOC consummated the private placement of 6,113,333 Private Placement Warrants at a price of $1.50 per Private Placement Warrant to the Sponsor, generating proceeds of $9.17 million.

 Each whole Private Placement Warrant is exercisable for one whole share of DTOC Class A Common Stock at a price of $11.50 per share, subject to adjustment. A portion of the proceeds from the sale of the Private Placement Warrants was added to the proceeds from DTOC's IPO held in the Trust Account. The Private Placement Warrants are non-redeemable for cash (except in certain limited circumstances) and exercisable on a cashless basis so long as they are held by the Sponsor or its permitted transferees.

 The Sponsor and DTOC's officers and directors agreed, subject to limited exceptions, not to transfer, assign or sell any of their Private Placement Warrants until 30 days after the completion of the initial business combination.

 Registration Rights

 The holders of Founder Shares and Private Placement Warrants (and any shares of DTOC Class A Common Stock issuable upon the exercise of the Private Placement Warrants), are entitled to registration rights pursuant to the amended and restated registration rights agreement dated September 20, 2023 (as amended, the "Registration Rights Agreement"). The Registration Rights Agreement will terminate on the earlier of (i) the tenth anniversary of the date of the Registration Rights Agreement and (ii) with respect to the Sponsor or any holder of registrable securities party thereto, the date that such person no longer holds any registrable securities.

 Related Party Notes

 On January 8, 2021, DTOC issued an unsecured promissory note to the Sponsor for an aggregate of up to $300,000 to cover expenses related to the IPO. This loan was non-interest bearing and payable on the earlier of December 31, 2021 or the completion of the IPO. During the period from January 8, 2021 to March 12, 2021, DTOC had borrowed $212,215 under the promissory note. On March 12, 2021, DTOC paid the balance on the note from the proceeds of the IPO.

 Upon the Closing of the Business Combination on September 20, 2023, the Company reimbursed the Sponsor an aggregate amount of $300,000 for payments made by the Sponsor in connection with its exercise of its options to extend the date by which DTOC is required to complete its initial business combination. In connection with such reimbursement, the obligations of the Company under certain non-interest bearing, unsecured promissory note issued in favor of the Sponsor were extinguished.

 In addition, in order to fund working capital deficiencies, finance transaction costs in connection with a business combination, or financing extension payments to the trust account in order to exercise of the option to extend the date by which DTOC is required to complete its initial business combination, the Sponsor or an affiliate of the Sponsor, or certain of DTOC officers and directors were permitted to, but were not obligated to, loan the Company funds as may be required ("Working Capital Loans"). Upon the Closing of the Business Combination, the Company repaid Working Capital Loans in the aggregate amount of $573,877.

 Certain Other Payments

 The Sponsor, executive officers and directors, or any of their respective affiliates has been reimbursed for any out-of-pocket expenses incurred in connection with activities on DTOC's behalf such as identifying potential target businesses and performing due diligence on suitable business combinations. DTOC's audit committee will review on a quarterly basis all payments that were made to the Sponsor, executive officers or directors, or DTOC's or their affiliates. The total amount of out-of-pocket expenses incurred by DTOC's officers and directors is less than $1,500.

 Sponsor Support Agreement

 AON and DTOC entered into an amended and restated sponsor support agreement (the "Sponsor Support Agreement") with the Sponsor and DTOC's Chief Executive Officer (together with the Sponsor, the "Supporting Sponsor Shareholders") pursuant to which the Supporting Sponsor Shareholders agreed not to transfer any shares of AON Class A Common Stock held by it until the twelve month anniversary of the Closing (the "Sponsor Lock-Up Period").

 In addition, under the Sponsor Support Agreement, the Sponsor has agreed to subject 2,839,375 of the shares of AON Class A Common Stock held by it as of the Closing (the "Sponsor Earnout Shares") to the following vesting and forfeiture provisions for the five-year period following the Closing: (i) the Sponsor Earnout Shares will vest when the volume-weighted average price of the AON Class A Common Stock equals or exceeds $13.50 per share for any 20 trading days within any thirty (30) trading day period beginning after the Closing and ending five (5) years following the Closing, (ii) all of the Sponsor Earnout Shares will be released immediately upon the consummation of a change of control transaction within the five (5)-year period following the Closing, and (iii) if the Sponsor Earnout Shares are not released pursuant to the foregoing provisions on or before the date that is five (5) years after the Closing, then the Sponsor Earnout Shares will be forfeited immediately following such date.

 The Sponsor Support Agreement will terminate in its entirety, and be of no further force or effect, upon the earlier to occur of (i) the expiration of the Sponsor Lock-Up Period, and (ii) the written agreement of the Sponsor and AON.

 Director Independence

 AON Class A Common Stock is listed on Nasdaq. Under the rules of Nasdaq, independent directors must comprise a majority of a listed company's board of directors. In addition, the rules of Nasdaq require that, subject to specified exceptions, each member of a listed company's audit, compensation and nominating and corporate governance committees be independent. We have a majority of independent directors on our Board. Under the rules of Nasdaq, a director will only qualify as an "independent director" if that company's board of directors affirmatively determines that such person does not have a material relationship with the listed company. Audit committee members must also satisfy the additional independence criteria set forth in Rule 10A-3 under the Exchange Act and the rules of Nasdaq.

 Compensation Committee members must also satisfy the additional independence criteria set forth in Rule 10C-1 under the Exchange Act and the rules of Nasdaq.

 In order to be considered independent for purposes of Rule 10A-3 under the Exchange Act and under the rules of Nasdaq, a member of an audit committee of a listed company may not, other than in his or her capacity as a member of the committee, the board of directors, or any other board committee: (1) accept, directly or indirectly, any consulting, advisory, or other compensatory fee from the listed company or any of its subsidiaries; or (2) be an affiliated person of the listed company or any of its subsidiaries.

 To be considered independent for purposes of Rule 10C-1 under the Exchange Act and under the rules of Nasdaq, the board of directors must affirmatively determine that a member of the compensation committee is independent, including a consideration of all factors specifically relevant to determining whether the director has a relationship to the 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: (i) the source of compensation of such director, including any consulting, advisory or other compensatory fee paid by the company to such director; and (ii) whether such director is affiliated with the company, a subsidiary of the company or an affiliate of a subsidiary of the company.

 Our Board has determined that Bradley Fluegel, Ravi Sarin, James Stith, and William J. Valle are independent under applicable Nasdaq and SEC rules.
