<PAGE>   2
                  2.1.     The purchase price at which Seller shall be entitled
                           to purchase shares of Class A Common Stock of Buyer
                           upon exercise of the Option shall be $0.10 per share.

                  2.2.     The Option shall be exercisable to the extent and in
                           the manner provided herein for a period of
                           twenty-four (24) months from the date of this
                           Agreement.

                  2.3.     Subject to the terms and conditions of this
                           Agreement, including the limitation set forth in
                           Section 2.2 above, the Option may be exercised in
                           whole at any time, or in part from time to time, by
                           delivery of written notice to the Buyer at its
                           principal executive office. Such notice shall state
                           the number of shares in respect of which the Option
                           is being exercised and shall be signed by Seller. If
                           requested by Buyer, Seller shall deliver this
                           Agreement to the Secretary of the Buyer who shall
                           endorse thereon a notation of such exercise.

                  2.4.     The notice of exercise described in Section 2.3 above
                           shall be accompanied by the full purchase price for
                           the shares in respect of which the Option is being
                           exercised, in cash or by check.

                  2.5.     Upon receipt of notice of exercise and full payment
                           for the shares in respect of which the Option is
                           exercised, Buyer shall take such action as may be
                           necessary to effect the transfer to Seller of the
                           number of shares as to which such exercise was
                           effective.

                  2.6.     Seller shall not be deemed to be the holder of, or to
                           have any of the rights of a holder with respect to
                           any shares subject to the Option until (i) the Option
                           shall have been exercised pursuant to the terms of
                           this Agreement and Seller shall have paid the full
                           purchase price for the numbers of shares in respect
                           of
<PAGE>   3
                           which the Option is exercised, (ii) Buyer shall have
                           issued and delivered to Seller certificates
                           evidencing the shares, and (iii) Seller's name shall
                           have been entered as a stockholder of record on the
                           books of Buyer, whereupon Seller shall have full
                           voting and other ownership rights with respect to
                           such shares.

                  2.7.     Buyer shall take such action as is necessary to
                           reserve a sufficient number of shares of Class A
                           Common Stock for issuance upon exercise of the
                           Option.

                  2.8.     The Option shall not be transferable other than by
                           will or by the laws of descent and distribution.
                           During the lifetime of Seller, the Option shall be
                           exercisable only by Seller. Any shares that Seller
                           acquires upon exercise of the Option may be
                           transferred freely upon registration under the
                           Securities Act and any applicable state securities
                           laws, or pursuant to an exemption from registration
                           under the Securities Act of 1933 and applicable state
                           securities laws.

                  2.9.     Subject to the terms and conditions of this
                           Agreement, upon the effective date of the liquidation
                           or dissolution of Buyer, the Option shall continue in
                           effect in accordance with its terms and Seller shall
                           be entitled to receive in respect of all shares
                           subject to the Option, upon exercise of the Option,
                           the same number and kind of stock, securities, cash,
                           property or other consideration that each holder of
                           shares was entitled to receive in such transaction.

                  2.10     If there shall be any capital reorganization, or
                           consolidation, or merger of the Buyer with any other
                           entity, or any sale of all or substantially all of
                           the Buyer's property
<PAGE>   4
                           and assets to any other entity, Buyer shall take
                           appropriate action to enable Seller to receive upon
                           any subsequent exercise of the Option, in whole or in
                           part, in lieu of any common shares of Buyer, the
                           share or shares, securities, interest or interests,
                           or other assets as were issuable or payable upon such
                           reorganization, consolidation, merger, or sale in
                           respect of or in exchange for such common shares.

                           issued upon exercise of an Option, unless at the time
