         WHEREAS, MIAMI is willing to sell its subscribers and have its
shareholders enter into a lock-up agreement pertaining to the disposition of the

         NOW, THEREFORE, in consideration of the mutual covenants and agreements
contained herein and for other good and valuable consideration, receipt of which
is hereby acknowledged, it is mutually agreed by and between the parties to this
Agreement as follows:

         (1) At the effective date of this Agreement, for each subscriber of
MIAMI, GREENHOLD will pay the shareholders of MIAMI one thousand (1,000) shares

         (2) All shares of GREENHOLD conveyed to the stockholders of MIAMI shall

                  No sale, offer to sell, or transfer of the shares represented
                  by this certificate shall be made unless a registration state-
                  ment under the Federal Securities Act of 1933, as amended,
                  with respect to such shares, is then in effect or an exemp-
                  tion from the registration requirements of said Act is then in
                  fact applicable to said shares.

                           ARTICLE II: EFFECTIVE TIME

         The effective time of this Agreement shall be such time as

         (1) This Agreement has been executed by the parties hereto; and

         (2) All stockholders of both corporations have executed Exhibit "A"
attached hereto and incorporated into this Agreement.

                         ARTICLE III: LOCK-UP PROVISIONS

         Upon such time as the stockholders of MIAMI are entitled to receive
their shares of GREENHOLD under the share offering as provided herein, those
stockholders hereby agree that the certificates issued on their behalf shall be
deposited with Dana M. Gallup, Esq. and retained subject to the following
lock-up provisions. Specifically, each such stockholder hereby agrees during the
Lock-Up Period, as hereinafter defined, that he or she shall not directly or
indirectly take any action designed to, or that may reasonably be expected to
cause or result in the stabilization or manipulation of the price of any
security of GREENHOLD to facilitate the sale or resale of the stock owned by
that stockholder; or take any action whatsoever that would be intended as a
transfer of that stockholder's share(s) in GREENHOLD in any direct or indirect
fashion whatsoever, recognizing that the share certificate is being held under
this Agreement by GREENHOLD. In the event that GREENHOLD shall secure the
services of an independent transfer agent during the tenure of this Agreement,
the stockholder agrees and consents to the entry of stop-transfer instructions
with GREENHOLD's transfer agent against the transfer of these shares held by the
stockholder, except in compliance with this Agreement.

                       ARTICLE IV: LOCK-UP PERIOD DEFINED

         It is agreed and understood by the stockholders who will be entitled to
GREENHOLD shares under this Agreement that the Lock-Up Period shall be defined
and shall operate as follows:





                                                                            E-27
<PAGE>   3

         (1) During the first twelve (12) months commencing form the Effective
Date of this Agreement, there shall be no sale of the shares of GREENHOLD.

         (2) Commencing with the thirteenth (13th) and continuing through the
thirty-second (32nd) month, if a stockholder so desires and indicates to Dana M.
Gallup, Esq. his or her desire to sell, then Dana M. Gallup, Esq. shall sell on
the public market, if such a market exists for this stock, five percent (5%) of
the number of shares owned by that stockholder, and shall continue to sell five
percent (5%) of those shares each month thereafter until otherwise notified by
the stockholder. If a stockholder shall elect, starting with the 13th month, not
to have his or her shares sold for a particular month, that stockholder shall
notify Dana M. Gallup, Esq. prior to the first (1st) day of the month of sale
that the shares are not to be sold, and in such case, a certificate for that
five percent (5%) of that stockholder's shares shall be issued and delivered to
him or her, as the case may be, on the 5th day of the month following. In the
case of any sales of stock, Dana M. Gallup, Esq. shall have the responsibility
of disbursing the net sale proceeds (without interest) to the stockholder on the
fifth day of the month following.

                          ARTICLE V: CHANGE OF CONTROL

         If GREENHOLD experiences a change of control, which, for the purpose of
this Agreement is defined as a sale of all or substantially all of its assets to
another Person (as defined below), or a merger or similar transaction which is
effected in such a way that GREENHOLD is not the surviving entity or shares of
its stock are to be cancelled in exchange for value (for purposes of this
Agreement, "Person" shall mean an individual, a limited liability company, a
partnership, a joint venture, a corporation, a trust, or an unincorporated
organization and/or a governmental department or agency), then GREENHOLD agrees
to release all shares held under the Lock-Up arrangement and distribute those
shares to the owners thereof.

                   ARTICLE VI: REPRESENTATIONS AND WARRANTIES

         Each corporation being a party to this Agreement represents and
warrants that it has the full power and authority to enter into this Agreement
