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.

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.
