meaning as set forth in the Service Agreement.

1.    Number of Option Shares: 65,000 shares (the "Option Shares")

2.    Exercise Price: $0.01 per Option Share.

3.    Type of Option: The Options shall not be considered as qualified stock
      options under Section 422 of the Internal Revenue Code. The Options are
      granted to Optionee's as compensation for personal services pursuant to
      Rule 701 under the Securities Exchange Act of 1933 (the "Act").

4.    Method of Exercise; Payment.

      (a)   Subject to paragraph 5 hereof, the Options may be exercised by the
            Optionee, in whole or in part and from time to time, by tendering to
            the Company at its principal office a notice of exercise form
            attached hereto as Appendix A duly executed, together with the Stock
            Option Agreement and payment to the Company by check of an amount
            equal to the Exercise Price multiplied by the number of Option
            Shares purchased.

      (b)   Promptly following receipt from the Optionee of the notices and
            instruments required for the Optionee to exercise the Options,
            including payment of the then applicable Exercise Price, the Company
            shall issue to the Optionee a certificate for the number of Option
            Shares acquired. If all of the Options are not exercised, the


            Company shall return the Stock Option Agreement to the Optionee,
            together with a written notice indicating the aggregate number of
            shares acquired upon the current and all prior exercises of the
            Options.

5.    Expiration of Options: The Options will expire on March 1, 1999. If

6.    Acknowledgments of Optionee: The Options granted pursuant to this Stock
      Option Agreement are personal to the Optionee and, prior to exercising
      such Options, may not be assigned or transferred to any other person
      except by will or the laws of descent and distribution. The Optionee
      acknowledges that he was informed that the Option Shares are not currently
      registered under the Act. Even after the Options are exercised, unless the
      Company has registered the Option Shares under the Act at that time, the
      Option Shares may not be transferred or otherwise disposed of unless the
      Option Shares are subsequently registered under the Act or an exemption
      from such registration is available. The Optionee was informed that the
      Company is under no obligation to register the Option Shares under the Act
      or to comply with any other applicable exemption under the Act with
      respect to the Option Shares. The undersigned will not sell or otherwise
      transfer the Option Shares, except by will or the laws of descent and
      distribution or except when such sale or transfer is made in compliance
      with the Act and all federal, state and local laws. The Optionee accepts
      the Options described herein in full satisfaction of all stock options and
      rights to receive any stock compensation under the Service Agreement.

7.    Restrictions on Transferability: The Option Shares granted upon exercise
      of the Options may not be transferred or assigned in whole or in part
      without compliance with applicable federal and state securities laws by
      the transferor and the transferee (including the delivery of investment
      representation letters and legal opinions reasonably satisfactory to the
      Company, if required by the Company). The Options Shares granted upon
      exercise of this the Options shall be imprinted with a legend in
      substantially the following form:


            "THESE SECURITIES ARE SUBJECT TO RESTRICTIONS ON TRANSFERABILITY AND
            RESALE AND MAY NOT BE TRANSFERRED OR RESOLD EXCEPT AS PERMITTED
            UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND THE APPLICABLE
            STATE SECURITIES LAWS, PURSUANT TO REGISTRATION OR EXEMPTION
            THEREFROM. INVESTORS SHOULD BE AWARE THAT THEY MAY BE REQUIRED TO
            BEAR THE FINANCIAL RISKS OF THIS INVESTMENT FOR AN INDEFINITE PERIOD
            OF TIME."

8.    Adjustment of Option Shares and Change in Capital Structure

      a.    The existence of outstanding Options shall not affect in any way the
            right or power of the Company or its stockholders to make or
            authorize any or all adjustments, recapitalizations, reorganizations
            or other changes in the Company's capital structure or its business,
            or any merger or consolidation of the Company, or any issuance of
            bonds, debentures, preferred or prior preference stock ahead of or
            affecting the Common Stock or the rights thereof, or the dissolution
            or liquidation of the Company, or any sale or transfer of all or any
            part of its assets or business, or any other corporate act or
            proceeding, whether of a similar character or otherwise.

      b.    If the Company shall effect a subdivision or consolidation of shares
            or other capital readjustment, the payment of a stock dividend, or
            other increase or reduction of the number of shares of the Common
            Stock outstanding, without receiving compensation therefor in money,
            services or property, then (1) the number, class, and per share
            price of shares of Common Stock subject to outstanding Options
            hereunder shall be appropriately adjusted in such a manner as to
            entitle the Optionee to receive upon exercise of an Option, for the
            same aggregate cash consideration, the same total number and class
            of shares as he would have received had the Optionee exercised his
            or her Option in full immediately prior to the event requiring the
            adjustment; and (2) the number and class of shares then reserved for
            issuance as a result of Options outstanding shall be adjusted by
            substituting for the total number and class of shares of Common
            Stock then reserved that number and class of shares of Common Stock
            that would have been received by the owner of an equal number of
            outstanding shares of each class of Common Stock as the result of
            the event requiring the adjustment.

      c.    After a merger of one or more corporations with the Company or after
            a consolidation of the Company and one or more


            corporations, Optionee shall, at no additional cost, be entitled
            upon exercise of such Option to receive (subject to any required
            action by stockholders) in lieu of the number and class of shares as
            to which such Option shall then be so exercisable, the number and
            class of shares of stock or other securities to which Optionee would
            have been entitled pursuant to the terms of the agreement of merger
            or consolidation if, immediately prior to such merger or
            consolidation, Optionee had been the holder of record of the number
            and class of shares of Common Stock equal to the number and class of
            shares as to which such Option shall be so exercised.

      d.    Except as previously expressly provided, neither the issuance by the
            Company of shares of stock of any class, or securities convertible
            into shares of stock of any class, for cash or property, or for
            labor or services either upon direct sale or upon the exercise of
            rights or warrants to subscribe therefor, or upon conversion of
            shares or obligations of the Company convertible into such shares or
            other securities, nor the increase or decrease of the number of
            authorized shares of stock, nor the addition or deletion of classes
            of stock, shall affect, and no adjustment by reason thereof shall be
            made with respect to, the number, class or price of shares of Common
            Stock then subject to outstanding Options.

      e.    Adjustment under the preceding provisions of this section will be
            made by the Board of Directors of the Company in good faith, whose
            determination as to what adjustments will be made and the extent
            thereof will be final, binding, and conclusive.

9.    Authorization and Reservation of Shares. During the term of this Stock
      Option Agreement, the Company will at all times have authorized and
      reserved a sufficient number of shares of its Common Stock to provide for
      the exercise of the rights to purchase Common Stock as provided for
      herein.

10.   No Fractional Share or Scrip. No fractional shares or scrip representing
      fractional shares shall be issued upon the exercise of the Optionee's
      rights to purchase Common Stock, but in lieu of such fractional shares the
      Company shall make a cash payment therefor upon the basis of the Exercise
      Price then in effect.

11.   Registry. The Company shall maintain a registry showing the name and
      address of the registered Optionee of this Stock Option Agreement.

12.   Miscellaneous. This Stock Option Agreement shall be governed by and
      construed under the laws of the State of Maryland. The titles of the
