Identity and Background

          This Amendment No. 22 is being filed by C. Michael Kojaian, KMC, KVMM, KV, and KH (collectively, the "Reporting Persons"). Item 2 of the Previous Filings is here incorporated by reference.

          During the last five years, none of the Reporting Persons has been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors). During the last five years, none of the Reporting Persons has been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction which resulted in the Reporting Person being subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

          Not applicable.

          The Reporting Persons are filing this Amendment No. 22 to make public their reservation of rights as detailed in their letter to the Company dated April 22, 2011 (the "Letter"). The Reporting Persons wrote and delivered the Letter in their capacities as stockholders of the Company. The Letter relates to the Company's Form 8-K Current Report dated March 30, 2011, in which the Company filed copies of a commitment letter with Colony Capital Acquisitions, LLC ("Colony") and an exclusivity agreement with Colony. Such Form 8-K is here incorporated by reference. In the Letter, the Reporting Persons reserved their rights as shareholders, including without limitation their rights to support or oppose any proposed transaction, to solicit Company shareholders to support or oppose any transaction, to discuss a transaction with Colony, to sell or purchase and/or solicit or discuss the sale or purchase of Common Stock, and to submit competing proposals. The Reporting Persons also insisted that the Company respect their contractual rights. The Letter was not intended to communicate any plans or proposals that the Reporting Persons may have which relate to or would result in the occurrence any of the topics listed in Item 4 of Schedule 13D under the Securities Act of 1934. The foregoing brief description of the Letter does not purport to be a full discussion of the Letter and is qualified by the Letter itself, which is attached as Exhibit 2 to this Amendment No. 22.

          The Reporting Persons may from time to time in the future acquire or dispose of additional securities of the Company in open market or privately negotiated transactions, depending on market conditions and other considerations that the Reporting Persons deem relevant. As of the date of this filing, the Reporting Persons have no specific plans or proposals to acquire or dispose of securities of the Company. The Reporting Persons also reserve the right to take any and all actions with respect to their respective investments in the Company as they from time to time may determine in the future in their sole discretion.

Item 5.

Interests in Securities of the Issuer

          (a-b)          The total number of shares of Common Stock deemed to be beneficially owned by all of the Reporting Persons is 22,908,209, which represents approximately 30.1% of the outstanding shares of Common Stock. The direct beneficial owners of such shares are represented in the following table (each Reporting Person has or has the right to acquire sole voting and dispositive power over the listed shares):

          The 6,060,600 shares of Common Stock directly owned by KMC reported above assumes the conversion of 100,000 shares of Grubb & Ellis Company 12% cumulative participating perpetual convertible preferred stock, par value $0.01 per share (the "Convertible Stock") at a rate of 60.606 shares of Common Stock for each share of Convertible Preferred Stock.

          As the sole member of KH, KMC is the deemed beneficial owner of, and has sole voting and dispositive power over, the 5,021,326 shares of Common Stock directly owned by KH. These shares of Common Stock represent approximately 7.2% of the outstanding shares of Common Stock.

          As the manager member of KV, KVMM is the deemed beneficial owner of, and has sole voting and dispositive power over, the 11,700,000 shares of Common Stock directly owned by KV. These shares represent approximately 16.7% of the outstanding shares of Common Stock.

          As (i) a 50% shareholder of KMC, (ii) the sole shareholder of KVMM and (iii) a member (along with KVMM) of KV, C. Michael Kojaian is deemed to be the beneficial owner of the 16,721,326 shares of Common Stock directly owned by KH and KV and the 6,060,600 shares of Common Stock directly beneficially owned by KMC (assuming the conversion of the Convertible Stock as discussed above). These shares of Common Stock, combined with the 126,283 C. Michael Kojaian holds directly for a total of 22,908,209 shares of Common Stock, represent approximately 30.1% of the outstanding shares of Common Stock. Of such 22,908,209 shares of Common Stock, C. Michael Kojaian has sole voting and dispositive power over the 11,700,000 shares of Common Stock directly owned by KV and the 126,283 shares of Common Stock he directly owns and shared voting and dispositive power over the 5,021,326 shares of Common Stock directly owned by KH and the 6,060,600 shares directly owned by KMC.

Board of Directors
Grubb & Ellis Company
1551 North Tustin Avenue
Suite 300
Santa Ana, CA 92705

Gentlemen:

                    Kojaian Ventures, L.L.C., Kojaian Holdings LLC, Kojaian Management Corporation and I, as a group (together the "Kojaian Shareholders") collectively are the beneficial owners (as determined under SEC regulations, including shares issuable upon conversion of convertible securities and exercise of options) of more than 30% of the common stock of Grubb & Ellis Company (the "Company"). This letter is provided on behalf of the Kojaian Shareholders solely in our capacity as shareholders of the Company.

                    Reference is made to the Company's Form 8-K Current Report dated March 30, 2011, in which the Company reported and filed copies of a commitment letter between Colony Capital Acquisitions, LLC ("Colony") and the Company dated March 30, 2011 (the "Commitment Letter") and an Exclusivity Agreement between Colony and the Company dated March 30, 2011 (the "Exclusivity Agreement"). For personal reasons, I was unable to participate in the Board of Director's consideration of the Commitment Letter, the Exclusivity Agreement, or other agreements subsequently entered into pursuant to the Commitment Letter. The purpose of this letter is to clarify my position regarding these agreements.

                    In the Exclusivity Agreement, the Company agrees that it shall, and that it shall cause its directors to, for a period of sixty days, work exclusively with Colony and its representatives with respect to a potential Transaction and not to solicit or initiate or enter into any discussions or transactions with, reply to or encourage, or provide any information to any individual, corporation, partnership, or other entity or group (other than Colony) concerning the acquisition of the Company or any subsidiary or any equity interest therein or all or any substantial portion of any of their assets.

                    The Company is advised that the Kojaian Shareholders are not, and I do not consider myself personally in my capacity as a shareholder and as a representative of the Kojaian Shareholders to be, bound by the Exclusivity Agreement. The Kojaian Shareholders expressly reserve all rights as shareholders of the Company with respect to any transaction or proposed transaction with Colony or others. These rights include, but are not limited to:

                    As the Company proceeds with its negotiation, execution and implementation of agreements for any future transaction with or proposed by or in connection with Colony, the Kojaian Shareholders expect and insist that the Company will fully respect and accommodate the rights of the Kojaian Shareholders, including those listed above and the rights of Kojaian investors relating to:

                    The purpose of this letter is to highlight and reserve the rights of the Kojaian Shareholders as shareholders of the Company. It is not intended to communicate or suggest any plan or proposal by the Kojaian Shareholders, or any of them, with respect to any of the topics mentioned in this letter or any of the actions enumerated in Item 4 of Schedule 13D under the Securities Act of 1934.

                    On a personal note, I would like to add that I am fully mindful of my fiduciary duties as a director of the Company and I sincerely intend to faithfully and fully perform those duties. The Company must, in turn, acknowledge that my duties as a director will not limit the range and exercise of the rights of the Kojaian Shareholders as shareholders of the Company, and respect those rights.

	Sincerely,
	/s/ C. Michael Kojaian
	C. Michael Kojaian On behalf of each of the Kojaian Investors named above
