consents, powers of attorney and other instruments).

     6. Non-compete, Non-solicitation.
        -----------------------------

        (a) The Executive acknowledges that in the course of his employment with
the Company he has become familiar, and he will become familiar, with the
Company's trade secrets and with other Confidential Information and that his
services have been and will be of special, unique and extraordinary value to the
Company. Therefore, the Executive agrees that he shall not, during the time

        (b) During the Covenant Period, the Executive shall not directly or
indirectly through another entity (i) directly induce or attempt to induce any
employee of or independent contractor to the Company or, to the extent known by
the Executive, the other Companies, to leave the employ of or breach contracts

between the Companies and any employee thereof, including without limitation,
inducing or attempting to induce any union, employee or group of employees to

distributor, franchisee, licensee or other business relation of the Company or,
to the extent known by the Executive, the other Companies, to cease doing

scope or area reasonable under such circumstances shall be substituted for the
stated duration, scope or area and that the court shall be allowed to revise the
restrictions contained herein to cover the maximum period, scope and area
permitted by law.

        (e) The Executive recognizes and affirms that in the event of his
material breach of any provision of this Section 6, money damages would be
inadequate and the Company would have no adequate remedy at law. Accordingly,
the Executive agrees that in the event of a breach or a threatened breach by the
Executive of any of the provisions of this Section 6, the Company, in addition
and supplementary to other rights and remedies existing in its favor, may apply
to any court of law or equity of competent jurisdiction for specific performance
and/or injunctive or other relief in order to enforce or prevent any violations
of the provisions hereof (without posting a bond or other security).

                  death or the Permanent Disability of the Executive (as
                  determined by the Board in its good faith judgment) shall not
                  be deemed to be a resignation by Executive.

                  (b) The Company and the Executive agree that the Company's
first recourse for non-payment of any Damages payable by the Executive pursuant
to the provisions set forth above shall be to the "Collateral" (as defined in

of the Collateral to be surrendered in payment of any Damages shall be
determined based on the "Collateral Valuation" determination provided in the
Pledge Agreement (as defined in paragraph (e) below).

                 (c) Executive and the Company agree that it is impossible to
determine with any reasonable accuracy the amount of prospective damages to
either party upon breach of this Agreement by the other. The Executive and the
Company further agree that the damages set forth above are reasonable, and not a
penalty, based upon the facts and circumstances of the parties at the time of
entering this Agreement, and with due regard to future expectations.

                 (d) If the Executive's employment hereunder is terminated by
the Company without Cause or is terminated due to the death or Permanent
Disability of the Executive, then the Executive shall not be required to pay any
Damages and shall be entitled to the return and release of all Collateral (as
defined below).

                 (e) As collateral for Executive's obligations under this
Agreement, Executive agrees to enter into that certain Pledge Agreement attached
hereto as Exhibit A (the "Pledge Agreement") in which Executive agrees to pledge
          ---------

proceeds received after the sale of such Pledged Shares in accordance with the
Pledge Agreement and such other collateral as allowed under the Pledge Agreement
(collectively, the "Collateral") shall be in an aggregate value at the Closing
Date equal to the Damages. In the event that the Executive does not pay the
Damages payable as determined in accordance with the schedule set forth in
Section 7(a) above within 30 days following the

     9. Miscellaneous.
        -------------

        (a) Severability. Whenever possible, each provision of this Agreement
            ------------
will be interpreted in such manner as to be effective and valid under applicable
law, but if any provision of this Agreement is held to be invalid, illegal or
unenforceable in any respect under any applicable law or rule in any
jurisdiction, such invalidity, illegality or unenforceability will not affect
any other provision or any other jurisdiction, but this Agreement will be
reformed, construed and enforced in such jurisdiction as if such invalid,
illegal or unenforceable provision had never been contained herein.

        (b) Complete Agreement. This Agreement and the agreements referred to
            ------------------
herein embody the complete agreement and understanding among the parties and
supersede and preempt any prior understandings, agreements or representations by
or among the parties, written or oral, which may have related to the subject
matter hereof.

        (c) Waiver of Jury Trial. The parties to this Agreement each hereby
            --------------------
waives, to the fullest extent permitted by law, any right to trial by jury of
any claim, demand, action, or cause of action (i) arising under this Agreement
or (ii) in any way connected with or related or incidental to the dealings of
the parties hereto in respect of

                                      -12-
<PAGE>

this Agreement or any of the transactions related hereto, in each case whether
now existing or hereafter arising, and whether in contract, tort, equity, or
otherwise. The parties to this Agreement each hereby agrees and consents that
any such claim, demand, action, or cause of action shall be decided by court
trial without a jury and that the parties to this Agreement may file an original
counterpart of a copy of this Agreement with any court as written evidence of
the consent of the parties hereto to the waiver of their right to trial by jury.

        (d) Counterparts; Facsimile Transmission. This Agreement may be executed
            ------------------------------------
simultaneously in two or more counterparts, any one of which need not contain
the signatures of more than one party, but all such counterparts taken together
will constitute one and the same Agreement. This Agreement may also be executed
and delivered by facsimile transmission.

        (e) Successors and Assigns. Except as otherwise provided herein, this
            ----------------------
Agreement shall bind and inure to the benefit of and be enforceable by the
Executive, the Company, and their respective successors and assigns.

        (f) Governing Law. All issues concerning this Agreement shall be
            -------------
governed by and construed in accordance with the laws of the State of Maryland,
without giving effect to any choice of law or conflict of law provision or rule
(whether of the State of Maryland or any other jurisdiction) that would cause
the application of the law of any jurisdiction other than the State of Maryland.

        (g) Remedies. Each of the parties to this Agreement will be entitled to
            --------
enforce its rights under this Agreement specifically, to recover damages and
costs (including reasonable attorneys' fees) caused by any breach of any
provision of this Agreement and to exercise all other rights existing in its
favor. The parties hereto agree and acknowledge that money damages may not be an
adequate remedy for any breach of the provisions of this Agreement and that any
party may in its sole discretion apply to any court of law or equity of
competent jurisdiction (without posting any bond or deposit) for specific
performance and/or injunctive or other relief in order to enforce or prevent any
violations of the provisions of this Agreement.

        (h) Amendment and Waiver. The provisions of this Agreement may be
            --------------------
amended and waived only with the prior written consent of the Company and the
Executive.
