Designated Individuals and Insider Employees (as defined in paragraph 5 below) are prohibited from holding the Company&rsquo;s

is seeking indemnification; after a Change in Control, the Reviewing Party shall be the Independent Counsel referred to below.
With respect to all matters arising after a Change in Control (other than a Change in Control approved by a majority of the directors
on the Board who were directors immediately prior to such Change in Control) concerning the rights of Indemnitee to indemnity
payments and Expense Advances under this Agreement or any other agreement or under applicable law or the Company&rsquo;s Amended
and Restated Certificate of Incorporation or bylaws now or hereafter in effect relating to indemnification for Indemnifiable Events,
the Company shall seek legal advice only from Independent Counsel selected by Indemnitee and approved by the Company and who has
not otherwise performed services for the Company or the Indemnitee (other than in connection with indemnification matters) within
the last five years. The Independent Counsel shall not include any person who, under the applicable standards of professional
conduct then prevailing would have a conflict of interest in representing either the Company or Indemnitee in an action to determine
Indemnitee&rsquo;s rights under this Agreement. Such counsel, among other things, shall render its written opinion to the Company
and Indemnitee as to whether and to what extent the Indemnitee should be permitted to be indemnified under applicable law. The
Company agrees to pay the reasonable fees of the Independent Counsel and to indemnify fully such counsel against any and all expenses
(including attorney&rsquo;s fees), claims, liabilities, loss, and damages arising out of or relating to this Agreement or the
engagement of Independent Counsel pursuant hereto.</P>

Regardless of any action by the Reviewing Party, if Indemnitee has not received full indemnification within 60 days after making
a request in accordance with Section 2(d), Indemnitee shall have the right to enforce its indemnification rights under this Agreement
by commencing litigation, in any appropriate court having subject matter jurisdiction thereof and in which venue is proper, seeking
an initial determination by the court or challenging any determination by the Reviewing Party or any aspect thereof, provided,
however, that such 60-day period shall be extended for reasonable time, not to exceed another 60 days, if the reviewing party
in good faith requires additional time for the obtaining or evaluating of documentation and information relating thereto. The
Company hereby consents to service of process and to appear in any such proceeding. Any determination by the Reviewing Party not
challenged by the Indemnitee shall be binding on the Company and Indemnitee. The remedy provided for in this Section 4 shall be
in addition to any other remedies available to Indemnitee in law or equity.</P>

Burden of Proof, and Presumptions</U>. It shall be a defense to any action brought by Indemnitee against the Company to enforce
this Agreement (other than an action brought to enforce a claim for Expenses incurred in defending a Proceeding in advance of
its final disposition where the required undertaking has been tendered to the Company) that is not permissible under applicable
law for the Company to indemnify Indemnitee for the amount claimed. In connection with any such action or any determination by
the Reviewing Party or otherwise as to whether Indemnitee is entitled to be indemnified hereunder, the burden of proving such
a defense or determination shall be on the Company. Neither the failure of the Reviewing Party or the Company (including its Board,
independent legal counsel, or its shareholders) to have made a determination prior to the commencement of such action by Indemnitee
that indemnification of the claimant is proper under the circumstances because Indemnitee has met the Standard of Conduct set
forth herein and under applicable law, nor an actual determination by the Reviewing Party or Company (including its Board, independent
legal counsel, or its shareholders) that the Indemnitee had not met such applicable Standard of Conduct, shall be a defense to
the action or create a presumption that the Indemnitee has not met the applicable Standard of Conduct. For purposes of this Agreement,
the termination of any claim, action, suit, or proceeding, by judgment, order, settlement (whether with or without court approval),
conviction, or upon a plea of nolo contendere, or its equivalent shall not create a presumption that Indemnitee did not meet any
particular standard of conduct or have any particular belief or that a court has determined that indemnification is not permitted
by applicable law.</P>

to assume the defense of any Proceeding, the Company shall not be liable to Indemnitee under this Agreement or otherwise for any
Expenses subsequently incurred by Indemnitee in connection with the defense of such Proceeding other than reasonable costs of

but all Expenses related thereto incurred after notice from the Company of its assumption of the defense shall be at Indemnitee&rsquo;s
expense unless: (i) the employment of legal counsel by Indemnitee has been authorized by the Company, (ii) Indemnitee has reasonably
determined that there may be a conflict of interest between Indemnitee and the Company in the defense of the Proceeding, (iii)
after a Change in Control, the employment of counsel by Indemnitee has been approved by the Independent Counsel, or (iv) the Company
shall not in fact have employed counsel to assume the defense of such Proceeding, in each of which case all Expenses of the Proceeding
shall be borne by the Company. The Company shall not be entitled to assume the defense of any Proceeding brought by or on behalf
of the Company or as to which Indemnitee shall have made the determination provided for in (ii) above.</P>

obligations I owe to any third party. I will not use or disclose to Company confidential information or trade secrets of any third
party without that party&rsquo;s consent. I acknowledge that Company wishes me to abide strictly by the terms of valid and enforceable
obligations I have to prior employers or clients, and that I am to inform an appropriate officer of the Company whenever I believe
a task I am to perform for the Company would put my ability to abide by those obligations at risk.</P>

If I am an employee, I will devote my full time and attention to the transaction of Company&rsquo;s business while I am employed

For one year after my employment or consulting relationship with Company terminates, regardless of the reason for termination,

with Company; (c) induce any person to leave the employment of Company; or (d) directly or indirectly hire or use the services
of any Company employee unless I obtain Company&rsquo;s written consent. I will not aid others in doing anything I am prohibited
from doing myself under this paragraph, whether as an employee, officer, director, shareholder, partner, consultant or otherwise.
For purposes of this paragraph, the term &ldquo;solicit&rdquo; includes (i) responding to requests for proposals and invitations
for bids, (ii) initiating contacts with customers, clients, or prospects of Company for the purpose of advising them that I no
longer am employed by or consulting for Company and am available for work which is competitive with the services offered by Company,
and (iii) participating in joint ventures or acting as a consultant or subcontractor or employee of others who directly solicit
business prohibited by this Agreement. The term &ldquo;Company employee&rdquo; includes any then current employee of Company or
any person who has left the employ of Company within the then previous six (6) months. The terms &ldquo;Company client&rdquo; and
&ldquo;Company customer&rdquo; include any parent corporation, subsidiary corporation, affiliate corporation or partner or joint
venture of a client or customer. &ldquo;Company prospect&rdquo; means any person or entity to whom Company has submitted a bid

this Agreement (other than an action brought to enforce a claim for Expenses incurred in defending a Proceeding in advance of
its final disposition where the required undertaking has been tendered to the Company) that is not permissible under applicable
law for the Company to indemnify Indemnitee for the amount claimed. In connection with any such action or any determination by
the Reviewing Party or otherwise as to whether Indemnitee is entitled to be indemnified hereunder, the burden of proving such
a defense or determination shall be on the Company. Neither the failure of the Reviewing Party or the Company (including its Board,
independent legal counsel, or its shareholders) to have made a determination prior to the commencement of such action by Indemnitee
that indemnification of the claimant is proper under the circumstances because Indemnitee has met the Standard of Conduct set
forth herein and under applicable law, nor an actual determination by the Reviewing Party or Company (including its Board, independent
legal counsel, or its shareholders) that the Indemnitee had not met such applicable Standard of Conduct, shall be a defense to
the action or create a presumption that the Indemnitee has not met the applicable Standard of Conduct. For purposes of this Agreement,
the termination of any claim, action, suit, or proceeding, by judgment, order, settlement (whether with or without court approval),
conviction, or upon a plea of nolo contendere, or its equivalent shall not create a presumption that Indemnitee did not meet any
particular standard of conduct or have any particular belief or that a court has determined that indemnification is not permitted
