                                  SCHEDULE 13D
                          FILED PURSUANT TO RULE 13d-1
                   OF THE GENERAL RULES AND REGULATIONS UNDER
                 THE SECURITIES EXCHANGE ACT OF 1934, AS AMENDED

Item 1. Security and Issuer.

            This Statement on Schedule 13D (this "Statement") relates to shares
of the common stock, par value $0.0001 per share (the "Common Stock"), of MIM
Corporation, a Delaware corporation (the "Issuer"). The Issuer's principal
executive offices are located at One Blue Hill Plaza, 15th Floor, P.O. Box 1670,
Pearl River, New York 10965-8670.

Item 2. Identity and Background.

      (a)-(c) The person filing this Statement is Mr. John H. Klein. Mr. Klein's
business address is c/o MIM Corporation, One Blue Hill Plaza, 15th Floor, P.O.
Box 1670, Pearl River, New York 10965-8670. Mr. Klein is the Chief Executive
Officer and Chairman of the Board of the Issuer, whose address is set forth
above in Item 1.

      (d)-(e) During the last five years, Mr. Klein (i) has not been convicted
in a criminal proceeding (excluding traffic violations or similar misdemeanors)
or (ii) was not a party to a civil proceeding of a judicial or administrative
body of competent jurisdiction and as a result of such proceeding was or is
subject to a judgment, decree or final order enjoining further violations of, or
prohibiting or mandating activities subject to, federal or state securities laws
or finding any violation with respect to such laws.

      (f)-(g) Mr. Klein is a citizen of the United State of America.

Item 3. Source and Amount of Funds or Other Consideration.

            Mr. Klein exercised 1,800,000 options ("Options") to purchase the
Issuer's Common Stock for an aggregate consideration of $180,000.00. These funds
were from Mr. Klein's personal assets.

Item 4. Purpose of the Transaction.

            Over the past several months, the price of the Insurer's Common
Stock has declined, culminating in the price of Issuer's Common Stock falling to
its historic low price on or about January 26, 1998. Mr. Klein determined that
it was in his personal best interest to exercise the Options at a time which was
most advantageous to him from a tax planning perspective.

            In addition, effective January 1, 1998, the Issuer's founder (the
"Founder") and then Vice Chairman went on administrative leave from all
responsibilities with the Issuer. The Founder had granted the Options to Mr.
Klein in May, 1996. Mr. Klein further determined that it was in his best
interest to secure voting control over these shares at such time. Accordingly,
Mr. Klein exercised the Options on January 26, 1998.

Item 5. Interest in Securities of the Issuer.

- -------------------                                            -----------------


            (a)-(b) Mr. Klein is the record and beneficial owner of 1,800,000
shares of Common Stock of the Issuer and has sole voting and dispositive power
with respect to such shares. In addition, Mr. Klein holds options to purchase an
additional 1,860,000 options to purchase Common Stock of which 1,240,000 are
currently exercisable at any time on or before April 30, 2006. Mr. Klein owns
beneficially an aggregate of 3,040,000 shares of Common Stock, representing
approximately 22.8% of the outstanding Common Stock of the Issuer.

            (c) Not applicable.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to
        Securities of the Issuer.

            The Issuer, Mr. Klein and certain other holders of Common Stock of
the Issuer and/or options to purchase Common Stock of the Issuer (collectively,
the "Holders") entered into Registration Rights Agreement-IV, dated July 29,
1996, as amended by Amendment No. 1 to Registration Rights Agreement-IV, dated
August 12, 1996 (the "Principal Registration Rights Agreement"), pursuant to
which the Issuer granted the Holders certain registration rights with respect to
the shares of Common Stock held by them.

            Mr. Klein and the Founder, Mr. E. David Corvese, entered into an
Option Agreement-II, dated May 30, 1996, as amended, whereby the Founder granted
Mr. Klein 1,860,000 options to purchase Common Stock at an exercise price equal
to $13.00 per share. To date, 620,000 of such options are unvested and
therefore, not currently exercisable.

            Other than the Registration Rights Agreement, no contracts,
arrangements, understandings or relationships (legal or otherwise) between Mr.
Klein and any other person (including the Issuer) exists with respect to any
securities of the Issuer, including but not limited to transfer or voting of any
such securities, finder's fees, joint ventures, loan or option arrangements,
puts or calls, guarantees of profits, division of profits or loss, or the giving
or withholding of proxies.

Item 7. Material to be Filed as Exhibits.

            None.
