Recitals
Whereas, subject to the terms and conditions of this Agreement, the Company
believes that it is in the best interest of the Company to appoint the New
Director to the Company’s Board of Directors (the “Board”); and
Whereas, subject to the terms and conditions of this Agreement, the Company
believes that it is in the best interest of the Company to appoint a second
director to the Board who is mutually agreeable to the parties and who shall be
considered “independent” as defined under the listing standards of The Nasdaq
Stock Market (the “Second Director” and together with the New Director, ach a
“Nia Director”).
Agreement
Now, Therefore, in consideration of the foregoing and other good and valuable
consideration, the receipt and sufficiency of which is hereby acknowledged, the
parties agree as follows:
1.Director Candidate.

1.1Board Candidates.

(i)Prior to the execution of this Agreement the Nominating and Corporate
Governance Committee of the Board (the “Nominating Committee”) has reviewed and
approved the qualifications of the New Director to serve as a member of the
Board. Promptly following the execution of this Agreement, the Company hereby
agrees that the Board shall appoint the New Director to the Board as a Class I
director to fill a current vacancy on the Board.

(ii)The Company hereby agrees that the Board shall appoint the Second Director
to serve as a member of the Board as a Class II director and shall expand the
size of the Board to nine directors accordingly. The timing of the appointment
of the Second Director shall be mutually agreed by the parties at such later
date and such appointment shall follow the Board’s normal candidate review
process for new directors.

1.2Termination. Notwithstanding anything else in this Agreement to the contrary,
if at any point in time (i) Nia does not beneficially own at least five percent
(5%) of the Company’s outstanding shares of voting capital stock (as such
ownership is calculated pursuant to the rules of The NASDAQ Global Market) (as
adjusted for any stock combinations, splits,

1

--------------------------------------------------------------------------------

recapitalizations and the like after the Effective Date), or (ii) Nia breaches
any provision of this Agreement (either such event, a “Termination Event”), upon
the Company’s request, the New Director and/or the Second Director, as the case
may be, shall promptly tender his or her resignation from the Board and any
committee of the Board on which he or she then sits and the Company shall not
have any further obligations under this Agreement. In order for the Company to
determine the occurrence of a Termination Event, Nia shall provide written
notice to the Company within two (2) business days following any transaction by
Nia which has the effect of decreasing the number of shares of the Company’s
voting capital stock that Nia beneficially owns (as such ownership is calculated
pursuant to the rules of The Nasdaq Stock Market).

1.3Replacement Director. In the event that a Nia Director is appointed to the
Board, if such Nia Director subsequently resigns or otherwise ceases to serve as
a director, other than due to a Termination Event, prior to the expiration of
the Voting Period (as defined below), the Nominating Committee shall use
commercially reasonable efforts to identify and vet suitable candidates for
appointment to the Board to replace such Nia Director, who shall be
“independent” as defined under the listing standards of The Nasdaq Stock Market
(each such candidate identified by the Nominating Committee and whom the
Nominating Committee recommends for consideration by Nia, a “Potential
Replacement Candidate”), and Nia shall be provided a reasonable opportunity to
interview each Potential Replacement Candidate and receive such other
information with respect to any Potential Replacement Candidate as Nia shall
reasonably request. Following Nia’s review of such Potential Replacement
Candidate, Nia shall provide written notice to the Nominating Committee as to
whether Nia approves of such Potential Replacement Candidate (any such Potential
Replacement Candidate identified by the Nominating Committee and so approved by
Nia, an “Approved Replacement Candidate”). Following the identification of an
Approved Replacement Candidate, the Company will use its commercially reasonable
efforts to appoint the Approved Replacement Candidate to the Board. The Approved
Replacement Candidate, once appointed to the Board, shall be deemed a “New
Director” or “Second Director”, as the case may be, for all purposes of this
Agreement.

1.4Director Questionnaire and Background Check. As an additional condition to
the appointment of a Nia Director to the Board, the Nia Director shall provide,
prior to such appointment to the Board, a completed D&O Questionnaire in the
form executed by the Company’s other directors, and the Company shall have
received acceptable results from a completed background check on the Nia
Director.

the Company legally or beneficially acquired by Nia after the date hereof
