Item 1.

Security and Issuer.

This Amendment No. 3 to Schedule 13D (this “Amendment”) relates to the common stock, par value $0.01 per share (the “Common Stock”), and voting and other contractual rights relating thereto, of National Health Investors, Inc., a Maryland corporation (the “Company”), which has its principal executive offices located at 100 Vine Street, Murfreesboro, Tennessee 37130.

This Amendment amends and supplements the Schedule 13D dated as of October 5, 2006 (the “Original Schedule 13D”) filed by W. Andrew Adams (“Andy”), AdamsMark, L.P., a Washington limited partnership (“AdamsMark”), Springland Ventures, L.P., a Washington limited partnership (“Springland”), Dorothy B. Adams, who is the wife of Andy (“Dorothy”), The Adams Group, L.P., a Washington limited partnership (“Adams Group”), Adams Children’s Trust, a Tennessee trust (the “Children’s Trust”), Adams Family Foundation II, a Tennessee private foundation (the “Foundation”), and W. Andrew and Dorothy B. Adams Grandchildren’s Trust, a Tennessee trust (the “Grandchildren’s Trust” and collectively with Andy, AdamsMark, Springland, Dorothy, Adams Group, the Children’s Trust, and the Foundation, the “Initial Reporting Persons”); the Amendment No. 1 to Schedule 13D dated as of November 8, 2006 filed by the Initial Reporting Persons (“Amendment No. 1”); and the Amendment No. 2 to Schedule 13D dated as of January 2, 2007 filed by the Initial Reporting Persons and Ira Sochet Revocable Intervivos Trust, Ira Sochet, Richmond Equities, LLC, Richmond Properties, LLC, William T. Richmond, Marcia L. Richmond, Martha P. Richmond, William T. and Martha P. Richmond Revocable Living Trust, East Main Associates, L.P., Charlotte A. Swafford, Harold R. Swafford, Will Edwards Settle, Eva D. DenBesten, Keneva, L.P., Kenneth D. DenBesten, James G. Baker, III, Michael Ussery, Beth Ussery, David L. Lassiter, Joanne Mott Batey, Kristin S. Gaines, Deryl Doran Johnson, D. Doran Johnson Associates, L.P., Amanda C. Johnson, Sara Elizabeth Johnson Baker, Candace Renee Johnson Malone, Adams Christian Trust (the “Christian Trust”), Carl E. Adams, Jr., Windsor Associates, L.P., Jennie Mae Adams, Fred M. Adams, Adams/Readyville Charitable Lead Annuity Trust, Adams Investments, L.P., Readyville Family, L.P., Adams Family Foundation, Sara Family L.P., Adams Charitable Lead Trust, Adams Grandchildren Trust I, Adams Grandchildren Trust II, Rutherford Associates, L.P., Tennessee Boulevard Investments, L.P., Coggin Family Limited Partnership, D. Gerald Coggin, A. B. Adams, Ann Lu Adams, PELTAK, L.P., Wendel M. Adams, Ernest G. Burgess, RAGS Family, L.P., and Sonya A. Leeman (“Amendment No. 2”).

The Original Schedule 13D described a proposal by Andy and AdamsMark of a transaction that, if approved and adopted by the Board of Directors of the Company (the “Board”) and the stockholders of the Company, would have resulted in the Common Stock no longer being publicly traded (the “Initial Proposal”). In light of the rejection of the Initial Proposal by the special committee of independent members of the Board (the “Committee”), Andy, on behalf of himself, AdamsMark, Springland, Dorothy, Adams Group, and the Children’s Trust (collectively, the “Initial Proponents”), orally submitted a revised proposal to the Committee on November 8, 2006, as disclosed in Amendment No. 1. In light of the Committee’s decision not to accept the revised proposal, AdamsMark, on behalf of the Initial Proponents, submitted a proposal letter to the Committee on December 1, 2 006 (the “December 1 Letter”). That proposal letter was to have been supplemented with subsequently delivered materials to constitute a new proposal. Before the supplemental materials were delivered to the Committee, however, the Initial Reporting Persons and the Designated Stockholders (as disclosed and defined in Amendment No. 2) sent a letter containing a new proposal to the Committee on January 2, 2007. That proposal, like the Initial Proposal, called for a transaction that, if approved and adopted by the Board and the stockholders of the Company, would have resulted in the Common Stock no longer being publicly traded (the “Subsequent Proposal”).

DALLAS 1752535v5

terminating the letter agreements pursuant to which they had agreed in principle, effective as of December 1, 2006, to participate in the merger and related transactions contemplated by the December 1 Letter. On April 4, 2007, AdamsMark, on behalf of itself and the other Reporting Persons (as defined below), sent a letter containing a new proposal to the Committee. That proposal, like the Initial Proposal and the Subsequent Proposal, is for a transaction that, if approved and adopted by the Board and the stockholders of the Company, would result in the Common Stock no longer being publicly traded (the “Proposal”).

This Amendment is filed by the Initial Reporting Persons and by the beneficial owners of the shares of Common Stock held by the stockholders named in Item 5(a) below (all such filing persons collectively, the “Reporting Persons”). Capitalized terms used but not defined in this Amendment have the respective meanings given them in the Original Schedule 13D, as amended by Amendment No. 1 and Amendment No. 2 (the “Previously Amended Schedule 13D”).

Item 3.

Source and Amount of Funds or Other Consideration.

Item 3 of the Previously Amended Schedule 13D is amended to read in its entirety as follows:

DALLAS 1752535v5

As more fully described in Item 4, the Proposal contemplates a series of related transactions, all occurring essentially simultaneously, that include (1) the Company’s sale and transfer of its assets, other than cash, and its liabilities, other than accrued dividends payable, to a newly formed limited partnership (the “UPREIT”) for an amount equal to $34.00 per share of Common Stock, less the amount of cash retained by the Company, payable partly in cash and partly by a promissory note of the UPREIT, (2) the Company’s declaration and payment of a dividend equal to $15.00 per share of Common Stock, payable either in cash or by issuance of 0.7894737 of a share of Common Stock, at the election of each holder of shares of Common Stock (the “Dividend”), and (3) the merger (the “Merger”) of the Company with an entity to be formed (the “Acquisition Entity 48;) that would hold shares of Common Stock contributed by certain stockholders of the Company that have agreed to so participate. As a result of the Merger, all of the outstanding shares of Common Stock, other than shares held by the Acquisition Entity, would be converted into cash or, at the election of each of the Company’s stockholders with at least 1,000 shares of Common Stock, shares of preferred stock of the Company as the survivor in the Merger (the “Surviving Entity”). It is anticipated that the cash to effect the UPREIT’s purchase of the Company’s assets, to pay the Dividend, and to pay cash in the Merger will be obtained from third-party financing, from personal funds of Andy, and through use of available cash and other liquid assets of the Company. Copies of two Conditional Commitment letters, dated November 29 and November 30, 2006, for debt financing from Column Financial, Inc., an affiliate of Credit Suisse (the “Financing Commitments 8;), were delivered to the Committee as part of the December 1 Letter and have been confirmed by Andy as applicable for the Proposal in the letter dated April 4, 2007 that made the Proposal (the “Proposal Letter”). The shares of preferred stock of the Surviving Entity that might be issued in the Merger will be issued by the Surviving Entity.

Item 4.

Purpose of Transaction.

Item 4 of the Previously Amended Schedule 13D is amended to read in its entirety as follows:

On April 4, 2007, the Proposal was made to the Committee by delivering the Proposal Letter, a copy of which is Exhibit G hereto and incorporated herein by reference. The Proposal is described below following a description of its background.

Background of the Proposal. At a regular Board meeting on August 2, 2006, Andy requested the Board to authorize the release of confidential information of the Company to certain possible financing sources for the purpose of evaluating whether it would be feasible for him or any of his other affiliated entities to make a proposal to acquire the Company. The Board authorized the release of information, subject to a confidentiality agreement or obligation of the recipients, and appointed the Committee to receive and consider any such proposal that might be made.

On October 5, 2006, Andy and AdamsMark orally submitted the Initial Proposal, to acquire the Company through a merger of the Company with and into a newly formed limited partnership, for consideration by the Committee. Under the Initial Proposal, each outstanding share of Common Stock would have been converted in that merger into $30.00 in cash, a preferred equity interest in the surviving limited partnership having a value of $30.00, or a common equity interest in the surviving limited partnership having a value of $30.00, or any combination of cash or such equity interests, at the election of each stockholder of the Company. The number of stockholders that could have elected to receive each class of equity interests in the surviving limited partnership would have been limited, however, so that the surviving limited

DALLAS 1752535v5

partnership would not have been required to register a class of equity securities under the Securities Exchange Act of 1934, as amended (the “Act”). The right of any holder to transfer any such equity interest after the merger would also have been restricted for the same reason. All of the shares of Common Stock owned of record by AdamsMark would have been converted into common equity interests in the surviving limited partnership. The merger would have been subject to third-party financing arranged by AdamsMark and to stockholders of the Company holding approximately $100 million of Common Stock (valued at the price per share in the Initial Proposal) electing to receive equity interests in the surviving limited partnership. The merger would have resulted in the surviving limited partnership being a privately held entity and the Company’s stockholders receiving the merger co nsideration in exchange for all of the outstanding shares of Common Stock.

Springland, Dorothy, Adams Group, the Children’s Trust, the Foundation, and the Grandchildren’s Trust indicated that they supported the Initial Proposal.

On October 6, 2006, Andy and AdamsMark were informed that the Committee considered the price per share in the Initial Proposal to be inadequate and that the Committee desired more particular information about other aspects of the Initial Proposal.

At a meeting with the Committee on November 8, 2006, Andy orally submitted a revised proposal to the Committee on behalf of the Initial Proponents. That proposal contemplated a merger of the Company with a newly formed entity that would hold shares of Common Stock contributed by certain stockholders of the Company under a separate agreement or arrangement with the Initial Proponents. In that merger, all of the outstanding shares of Common Stock, other than those held by the newly formed entity (which would have been cancelled), would have been converted into cash in an amount per share greater than $30.00 or shares of senior preferred stock of the Company as the surviving entity in that merger having the equivalent value, or a combination of cash and senior preferred stock, at the election of each holder of such shares of Common Stock. As the result of that merger, the st ockholders of the Company, other than the newly formed entity, would have received the merger consideration in exchange for the outstanding shares of Common Stock (which would no longer have been listed on the New York Stock Exchange and would have been eligible for termination of registration pursuant to Section 12(g)(4) of the Act). That proposal was subject to two contingencies, third-party financing arranged by the Initial Proponents and agreements with those stockholders of the Company that would own the newly formed entity for the merger.

At the meeting, the Committee indicated that, before it could accept the revised proposal, it must have evidence that certain contingencies could be satisfied.

On December 1, 2006, AdamsMark, on behalf of the Initial Proponents, delivered the December 1 Letter to the Committee. The December 1 Letter was accompanied by copies of the Financing Commitments. The Initial Proponents expected, however, that no proposal would be made to or considered by the Committee until the December 1 Letter was supplemented by a list of stockholders of the Company who agreed to become, and a copy of the form of the agreement by which they became, Designated Stockholders.

On December 6, 2006, the Initial Proponents received a letter from the Committee’s counsel requesting delivery of certain items of information as a condition to the Committee’s consideration of the December 1 Letter as a proposal. Those items included (1) the anticipated list of Designated Stockholders and their agreements and (2) a description of the anticipated

DALLAS 1752535v5

sources of capital for the merger and related transactions described in the December 1 Letter. On December 19, 2006, the Committee’s counsel acknowledged in a letter that those items were the only items that the Committee was awaiting. By that date, however, the Initial Proponents and the Designated Stockholders, the agreements of which were being signed, had determined that the transactions in the December 1 Letter should be revised, and they were formulating a new proposal letter to supersede the December 1 Letter. They also had discussions with National HealthCare Corporation (“NHC”) and National HealthCare Realty Corporation (“NHR”) regarding the purchase by the Company (immediately before the merger) of respective shares of Common Stock owned by NHC and NHR if the merger and related transactions were to be effected, and those discussions resulted in letters of inten t with NHC and NHR.

The Initial Reporting Persons and the Designated Stockholders sent a letter containing the Subsequent Proposal to the Committee on January 2, 2007 (the “January 2 Letter”). The Subsequent Proposal contemplated a series of related transactions, all occurring essentially simultaneously, that included (1) the Company’s sale and transfer of its assets, other than cash, and its liabilities, other than accrued dividends payable, to a newly formed limited partnership for an amount equal to $33.00 per share of Common Stock, less the amount of cash retained by the Company, payable partly in cash and partly by a promissory note of the limited partnership, (2) the Company’s declaration and payment of a dividend equal to $15.00 per share of Common Stock, payable either in cash or by issuance of 0.8333 of a share of Common Stock, at the election of each holder of shares of Common St ock, and (3) the merger of the Company with an entity to be formed that would hold shares of Common Stock contributed by the Designated Stockholders.

On February 2, 2007, AdamsMark received a letter dated February 1, 2007 from the Committee stating, among other things, that the Committee unanimously concluded not to accept the Subsequent Proposal. On February 2, 2007, the Company also issued a press release acknowledging the Committee’s response and stating that the Committee unanimously believed that continuing to operate the Company as a public company would create greater value for public stockholders than the Subsequent Proposal and that the Committee requested that management further develop and implement a wide-ranging strategic plan to enhance the business and stockholder value of the Company.

Following the Committee’s rejection of the Subsequent Proposal, Andy continued to consider the possibility of making another proposal and, on occasion, had informal discussions with individual members of the Committee and counsel to the Committee about certain aspects of a possible new proposal. On February 13, 2007, AdamsMark sent a letter to each of the Designated Stockholders terminating the letter agreements pursuant to which they had agreed in principle to participate in the merger and related transactions contemplated by the December 1 Letter. None of the Designated Stockholders other than the Reporting Persons are now participating in the Proposal.

Description of the Proposal. As described in the Proposal Letter, the Proposal contemplates a series of related transactions, to occur essentially simultaneously, but in the following order:

NHC would sell all, and NHR would sell a portion, of its shares of Common Stock to the Company for $34.00 per share, payable by delivery of a secured promissory note of the Company or the Surviving Entity upon and after the Merger.

DALLAS 1752535v5

An affiliate of Andy would organize and act as the sole general partner of the UPREIT, which would purchase all of the Company’s assets, other than cash, and assume all of the Company’s liabilities, other than accrued dividends payable, for a purchase price in an amount equal to $34.00 per share of Common Stock, less the amount of cash retained by the Company. The purchase price would be payable partly in cash and partly by delivery of a promissory note of the UPREIT.

The Company would declare and pay the Dividend equal to $15.00 per share of Common Stock. The Dividend would be paid, as determined by each holder of Common Stock, either in cash or by issuance and delivery of 0.7894737 of a share of Common Stock.

The Reporting Persons would contribute all or most of their shares of Common Stock to the Acquisition Entity. The Merger Agreement (as defined below) would provide that additional stockholders of the Company could, if so invited, contribute their shares of Common Stock to the Acquisition Entity after the Board exempted the transaction from the Maryland Business Combination Act and the Maryland Control Share Acquisition Act and after the approval and execution of the Merger Agreement.

The Company and the Acquisition Entity would enter into a merger agreement (the “Merger Agreement”) and effect the Merger. In the Merger, all of the outstanding shares of Common Stock, other than those held by the Acquisition Entity (which would be cancelled), would be converted into $19.00 per share in cash or shares of preferred stock of the Surviving Entity with the terms described below (the “Preferred Stock”) having a value of $19.00 per share of Common Stock, or a combination of cash and Preferred Stock, at the election of each holder of such shares of Common Stock that owns at least 1,000 shares of Common Stock (collectively, the “Merger Consideration”). (Any holder of fewer than 1,000 shares of Common Stock would receive only cash for those shares in the Merger.) Also in the Merger, the equity interests in the Acquisition Entity would be converted into shar es of common stock of the Surviving Entity (“Surviving Entity Common Stock”) and shares of Preferred Stock.

In general, the Preferred Stock of the Surviving Entity would (a) be entitled to an annual cumulative dividend of $1.25 per share (but no other dividend or distribution); (b) be convertible at the holder’s option, at any time after December 31, 2009, into shares of Surviving Entity Common Stock at a conversion premium of 10% (i.e., at the rate of 0.9091 of a share of Surviving Entity Common Stock for each share of Preferred Stock); (c) be subject to mandatory redemption or repurchase by the Surviving Entity on December 31, 2027 for the sum of the liquidation value of $19.00 per share plus all then accrued and unpaid dividends; (d) have a preference over the other shares of capital stock of the Surviving Entity as to dividends and upon liquidation (with the liquidation value of $19.00 per share); (e) be non-voting except as provided by law; and (f) not be transferable by the holder except to the Survivi ng Entity or any other stockholder of the Surviving Entity or by operation of law unless the holders of Preferred Stock equal or exceed 500 (which is not now anticipated).

As necessary to comply with REIT ownership rules, certain of the Reporting Persons would elect to receive cash as the Merger Consideration for their shares of Common Stock not contributed to the Acquisition Entity and would use that cash to purchase limited partnership interests in the UPREIT. The Surviving Entity would purchase limited partnership interests in the UPREIT in an amount equal to $19.00 times the

DALLAS 1752535v5

number of outstanding shares of Surviving Entity Common Stock.

To provide stockholders of the Company that elect to remain invested in the Surviving Entity with cash to pay at least a portion of the tax arising out of the sale of assets of the Company to the UPREIT (as described above), the Surviving Entity would declare and pay to all holders of Surviving Entity Common Stock and Surviving Entity Preferred Stock a one-time dividend of $1.00 per share.

As the result of the Merger and these related transactions, (1) substantially all of the assets and liabilities of the Company before the Merger would be owned by the UPREIT upon and after the Merger; (2) the UPREIT would be owned by the Surviving Entity, certain of the Reporting Persons and an entity affiliated with Andy upon and after the Merger; (3) the Surviving Entity would be owned by the Reporting Persons and any stockholders of the Company that elect to receive shares of Preferred Stock in the Merger as a privately held real estate investment trust (unless, as is not now anticipated, there are 500 or more holders of the Preferred Stock, which would require registration of the Preferred Stock under the Act), and (4) the stockholders of the Company, other than the Acquisition Entity, would receive the Dividend and the Merger Consideration in exchange for the outstanding shares of Common St ock.

The Proposal Letter includes, as Exhibit A thereto, a non-exclusive list of reasons that the Reporting Persons believe the Proposal to be in the best interests of all of the Company’s stockholders.

The Proposal Letter also includes statements of (1) Andy’s belief that if the Committee does not recommend, or the Board does not approve, the Proposal, the Board should aggressively market the Company for sale at a higher price, and (2) Andy’s intention, in that circumstance, to fully support efforts to effect such a sale.

If the Merger and related transactions are effected, the Common Stock would no longer be listed on the New York Stock Exchange and would be eligible for termination of registration pursuant to Section 12(g)(4) of the Act. The Board has appointed the Committee to review and consider the Proposal. For the Merger and related transactions to be effected, they would require authorization of the Board (in light of a recommendation of the Committee), the execution of a definitive Merger Agreement, and the satisfaction of various conditions to be set forth in the Merger Agreement, including the approval of the stockholders of the Company.

Other than as set forth in the preceding paragraphs, none of the Reporting Persons has any specific plans or proposals which relate to or would result in any extraordinary corporate transaction, such as a merger, reorganization or liquidation, involving the Company or any of its subsidiaries; a sale or transfer of a material amount of assets of the Company or any of its subsidiaries; any change in the present board of directors or management of the Company; any material change in the present capitalization or dividend policy of the Company; any other material change in the Company’s business or corporate structure; changes in the Company’s charter, bylaws or instruments corresponding thereto or other actions which may impede the acquisition of control of the Company by any person; causing a class of securities of the Company to be delisted from a national securities exchange or to ceas e to be authorized to be quoted in an inter-dealer quotation system of a registered national securities association; a class of equity securities of the Company becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Act; or any action similar to any of those enumerated above; but each of such Reporting Persons reserves the right to propose or undertake or participate in any of the

DALLAS 1752535v5

foregoing actions in the future.

The percentage calculation is based upon 27,756,091 shares of Common Stock outstanding on March 22, 2007, which is the number of shares of Common Stock reported in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2006, and filed with the Securities and Exchange Commission on March 23, 2007.

(b)

As described in Item 5(a), because the Reporting Persons may be deemed a “group,” each Reporting Person may be deemed to share voting and dispositive power with each other Reporting Person. Nevertheless, the following describes the particular relationships between the Reporting Persons regarding voting and dispositive power over shares of

DALLAS 1752535v5

Common Stock:

Andy is the sole general partner of AdamsMark and Springland and therefore has sole voting and dispositive power over the 546,411 shares beneficially owned by AdamsMark and over the 44,000 shares beneficially owned by Springland. Andy is also one of the trustees of each of the Children’s Trust, the Foundation, the Grandchildren’s Trust, the Christian Trust, Adams Grandchildren Trust I, and Adams Family Foundation and therefore shares voting and dispositive power with the other trustees over the 3,250 shares beneficially owned by the Children’s Trust, the 222,307 shares beneficially owned by the Foundation, the 6,500 shares beneficially owned by the Grandchildren’s Trust, the 86,594 shares beneficially owned by the Christian Trust, the 71,600 shares beneficially owned by Adams Grandchildren Trust I, and the 44,390 shares beneficially owned by Adams Family Foundation.

Dorothy, Andy’s wife, is the sole general partner of Adams Group and one of the two trustees, with Andy, of each of the Children’s Trust and the Christian Trust; each of Dorothy and Andy as trustee has the power to act independently on behalf of each of the Children’s Trust and the Christian Trust. Andy has influence over Dorothy’s decisions as the general partner of Adams Group regarding the voting and disposition of shares held by Adams Group. Therefore, Dorothy shares voting and dispositive power with Andy over the 1,864,043 shares beneficially owned by Adams Group, over the 3,250 shares beneficially owned by the Children’s Trust, and over the 86,594 shares beneficially owned by the Christian Trust. Dorothy is also one of the trustees of the Grandchildren’s Trust and therefore shares voting and dispositive power with the other trustees over the 6,500 shares beneficially owned by the Grandchildren’s Trust.

Jennie Mae Adams, Andy’s mother, has sole voting and dispositive power over the 27,500 shares that she beneficially owns individually. She is the sole general partner of Windsor Associates, L.P. and therefore has sole voting and dispositive power over the 321,895 shares beneficially owned by Windsor Associates, L.P. She is also one of the trustees of each of Adams Family Foundation and Adams Grandchildren Trust II and therefore shares voting and dispositive power with the other trustees over the 44,390 shares beneficially owned by Adams Family Foundation and over the 11,891 shares beneficially owned by Adams Grandchildren Trust II.

Carl E. Adams, Jr., Andy’s brother, has sole voting and dispositive power over the 126,000 shares that he beneficially owns individually. He is also one of the trustees of each of Adams Family Foundation and Adams Grandchildren Trust I and therefore shares voting and dispositive power with the other trustees over the 44,390 shares beneficially owned by Adams Family Foundation and the 71,600 shares beneficially owned by Adams Grandchildren’s Trust I.

Fred M. Adams, Andy’s brother, has sole voting and dispositive power over the 33,637 shares that he beneficially owns individually. He is the sole trustee of Adams/Readyville Charitable Lead Annuity Trust and the sole general partner of each of Adams Investments, L.P. and Readyville Family, L.P. and therefore has sole voting and dispositive power over the 3,500 shares beneficially owned by Adams/Readyville Charitable Lead Annuity Trust, the 361,769 shares beneficially owned by Adams Investments, L.P., and the 12,606 shares beneficially owned by Readyville Family, L.P. He is also one of the trustees of each of Adams Family Foundation, Adams

DALLAS 1752535v5

Grandchildren Trust I, and Adams Grandchildren Trust II and therefore shares voting and dispositive power with the other trustees over the 44,390 shares owned by Adams Family Foundation, the 71,600 shares beneficially owned by Adams Grandchildren Trust I, and the 11,891 shares beneficially owned by Adams Grandchildren Trust II.

Robert G. Adams, Andy’s brother, is the sole trustee of Adams Charitable Lead Trust and the sole general partner of Sara Family, L.P. and therefore has sole voting and dispositive power over the 20,000 shares beneficially owned by Adams Charitable Lead Trust and the 269,906 shares beneficially owned by Sara Family, L.P. He is also one of the trustees of each of Adams Family Foundation and Adams Grandchildren Trust I and therefore shares voting and dispositive power with the other trustees over the 44,390 shares beneficially owned by Adams Family Foundation and the 71,600 shares beneficially owned by Adams Grandchildren Trust I.

Andy shares voting and dispositive power with Dorothy and their three adult offspring, Andrew Adams, Andrea A. Brown, and Anthony Adams (collectively, the “Offspring”), over the 222,307 shares of Common Stock owned directly by the Foundation and over the 6,500 shares of Common Stock owned directly by the Grandchildren’s Trust. Andy, Dorothy, and the Offspring are the sole trustees of the Grandchildren’s Trust.
