herein, Employee's employment is terminated for other than cause or Employee
refused to accept or voluntarily resigns from a position other than a Qualified

"Change in Control" means the acquisition, directly or indirectly of more than
..40% of the outstanding shares of any class of voting securities of the Company

of this Agreement, or a merger, consolidation or sale of all or substantially
all of the assets of the Company, such that the individuals constituting the
Board of the Company immediately prior to such period shall cease to constitute
a majority of the Board, unless the election of each director who was not a
director prior thereto was approved by vote of at least two-thirds of the
directors then in office who were directors prior to such period.

the Change in Control with substantially the same responsibilities as those held
by the Employee on the date of the Change in Control. Also, notwithstanding the
foregoing, if the Company determines that the amounts payable to Employee under
this employment agreement, when considered together within the other amounts
payable to Employee as a result of a Change in Control, cause such payments to
be treated as excess parachute payments within the meaning of Section 280G of
the Internal Revenue Code, the Company shall reduce the amount payable to
Employee under this Section 4(d) to an amount that will not subject Employee to
the imposition of tax under Section 4999 of the Internal Revenue Code; provided,
however, that this provision shall apply only to payments to be made under this
employment agreement and Employee by the Company.

5. Notice of Breach. The Company and the Employee agree that, prior to the
termination of the Employment Period by reason of any breach of any provision,
of the Agreement, the injured party will give the party in breach written
notice, specifying such breach and permitting the party in breach to cure such
breach within a period of thirty (30) days after receipt of such notice, except
a breach by Employee of provisions of Section 7 of this Agreement shall not have
a cure period.

the Company or is or was serving at the request of the Company as a director,
officer, member, employee or agent of another corporation or partnership, joint
venture, trust or other enterprise, including service with respect to employee
benefit plans, whether or not the basis of such Proceeding is an alleged act or
failure to act in an official capacity as a director, officer, member, employee
or agent, he shall be indemnified and held harmless by the Company to the
fullest extent authorized by Delaware law, as the same exists or may hereafter
be amended, against all expense, liability and loss (including, without
limitation, attorney's fees, judgments, fines and amounts paid or to be paid in
settlement) reasonably incurred or suffered by the Employee in connection
herewith, including, without limitation, payment of expenses incurred in
defending a Proceeding prior to the final disposition of such Proceeding

indemnified by the Company under Delaware law), and such indemnification shall
continue as to the Employee even if he has ceased to be a director, officer,

the following:

           (1) the conviction of the Executive under state or federal law of a
               felony or other crime, or the equivalent under foreign law;
               unless in any such case Executive performed such act in good
               faith and in a manner reasonably believed to be in or not opposed
               to the best interests of the Company;

           (2) the material breach by Executive of any provision of the
               Agreement which has not been cured pursuant to the provisions of
               Section 5 hereof; or

           (3) a determination or request by an appropriate regulatory authority
               that the Executive be removed or disqualified from acting as an
               officer of the Company.

        (b) If the Executive's services are terminated for other than cause by
the Company, then the Contractor is entitled to termination payments equal to
the lesser of (i) four (4) months of the current monthly payment payable in a
lump sum payment on the last day of the thirty (30) day notice period or (2) the
remaining current monthly payment amount for the term of this Agreement payable
in a lump sum payment on the last day of the thirty (30) day notice period.

        (c) The Executive shall have the right at his sole option to terminate
his services at any time upon sixty (60) days written notice or for such other
notice period to be determined by the Board at its sole discretion.

        (d) If within twelve (12) months of a Change in Control, as that term is
defined herein, Executive's services are terminated for other than cause or
Executive refused to accept or voluntarily resigns from a position other than a
Qualified Position, as that term is defined herein, Contractor shall receive
severance compensation equal to twelve (12) months of the then current monthly
payment. A "Change in Control" means the acquisition, directly or indirectly of
more than 40% of the outstanding shares of any class of voting securities of the
Company by one person or one entity that is not an existing shareholder as of
the date of this Agreement, or a merger, consolidation or sale of all or
substantially all of the assets of the Company, such that the individuals
constituting the Board of the Company immediately prior to such period shall
cease to constitute a majority of the Board, unless the election of each
director who was not a director prior thereto was approved by vote of at least
two-thirds of the directors then in office who were directors prior to such
period. Notwithstanding the foregoing, an acquisition of the requisite
percentage of voting securities in connection with a public offering of
securities by the Company for the primary purpose of providing capital resources
to the Company shall not be considered a "Change in Control" for purposes of
this Section 4(d). "Qualified Position" is an executive officer position with
the entity surviving the Change in Control with substantially the same
responsibilities as those held by the Executive on the date of the Change in
Control. Also, notwithstanding the foregoing, if the Company determines that the
amounts payable to Contractor under this Agreement, when considered together
within the other amounts payable to Contractor as a result of a Change in
Control, cause such payments to be treated as excess parachute payments within
the meaning of Section 280G of the Internal Revenue Code, the Company shall
reduce the amount payable to Contractor under this Section 4(d) to an amount
that will not subject Contractor to the imposition of tax

                                       3
<PAGE>

under Section 4999 of the Internal Revenue Code; provided, however, that this
provision shall apply only to payments to be made under this Agreement and shall
not cause the reduction of any other payments to be made to Contractor by the
Company.

4. Notice of Breach. The Company and the Contractor agree that, prior to the
termination of the Service Period by reason of any breach of any provision of
the Agreement, the injured party will give the party in breach written notice,
specifying such breach and permitting the party in breach to cure such breach
within a period of thirty (30) days after receipt of such notice, except a
breach by Executive of provisions of Section 6 of this Agreement shall not have
a cure period.

5. Indemnification.

        (a) If, after the date of the commencement of the Service Period, the
Executive is made a party or is threatened to be made a party to any action,
suit or proceeding, whether civil, criminal, administrative or investigative (a
"Proceeding"), by reason of the fact that he is or was a director or officer of
the Company or is or was serving at the request of the Company as a director,
officer, member, employee or agent of another corporation or partnership, joint
venture, trust or other enterprise, including service with respect to employee
benefit plans, whether or not the basis of such Proceeding is an alleged act or
failure to act in an official capacity as a director, officer, member, employee
or agent, he shall be indemnified and held harmless by the Company to the
fullest extent authorized by Delaware law, as the same exists or may hereafter
be amended, against all expense, liability and loss (including, without
limitation, attorney's fees, judgments, fines and amounts paid or to be paid in
settlement) reasonably incurred or suffered by the Executive in connection
herewith, including , without limitation, payment of expenses incurred in
defending a Proceeding prior to the final disposition of such Proceeding
(subject to receipt of an undertaking by the Executive to repay such amount if
it shall ultimately be determined that the Executive is not entitled to be
indemnified by the Company under Delaware law), and such indemnification shall
continue as to the Executive even if he has ceased to be a director, officer,
member, employee or agent of the Company or other enterprise and shall inure to
the benefit of his heirs, executors and administrators.

        (b) The right of indemnification and the payment of expenses incurred in
defending a Proceeding in advance of its final disposition conferring in this
Section 5 shall not be exclusive of any other right that the Executive may have
or hereafter may acquire under any statute, provision of the Certificate of
Incorporation or Bylaws of the Company, agreement, vote of shareholders or
disinterested directors or otherwise.

6. Trade Secrets of the Company. Patents and Inventions.

        (a) Except as required by the performance of the Executive's services to
the Company under the terms of this Agreement, neither the Executive or any of
his agents or representatives, shall, during his employment and for so long

                 non-public business information. Confidential Information does
                 not include any information which (1) was in the lawful and

                 "know-how" related thereto, relating at the time of conception
