specified in clause (a), (ii) to include in the slate of nominees
recommended by the Board the Investor Representatives, the ITI

the Certificate of Designation. The Company agrees to use its reasonable
best efforts to cause the election of the Representatives to the Board,
including nominating such individuals to be elected as Directors as
provided herein.
(c) Each of the Investor Stockholders, ITI and Casty agrees to vote,
or act by written consent with respect to any Voting Securities
beneficially owned by him or it, at each annual or special meeting of the
stockholders of the Company at which Directors are to be elected or to take
all actions by written consent in lieu of any such meeting as are necessary
to cause the Representatives designated by the others in accordance with
the terms of this Agreement to be elected to the Board and agrees to use
his or its reasonable best efforts to cause the election of each such
designee to the Board, including nominating such individuals to be elected
as Directors.
(d) In the event that a vacancy is created at any time by the death,
disability, retirement, resignation or removal (with or without cause) of
any Representative, the remaining Directors and the Company shall cause the
vacancy created thereby to be filled by a new designee of the party or
parties that designated such Director as soon as possible, who is
designated in the manner specified in this Section 2.1. Each of the

the former.
(e) Without the written consent of the Investor Stockholders, each of
the Company, ITI and Casty agrees not to take any action that would cause
the number of Directors constituting the entire Board to be other than
seven (7).
(f) The covenants and agreements set forth herein shall be subject to
the fiduciary obligations of the designees of the Investor Stockholders,
ITI and Eidelstein now or hereafter serving on the Board and shall not
prevent the designees of the Investor Stockholders, ITI or Eidelstein now
or hereafter serving on the Board from taking any action or refraining to
take any action while acting in the capacity as a Director of the Company.
The foregoing shall not limit the obligations of the Investor Stockholders,
ITI and Eidelstein in their capacity as stockholders of the Company
hereunder.
3. Section 3.4 is amended to read as follows:
SECTION 3.4 Transfers by Casty.
------------------

Transfer more than the number of Shares of Common Stock permitted under

Investor Stockholders, which consent shall not be unreasonably withheld or
delayed or without compliance with Sections 3.5 and 3.6. Notwithstanding
the foregoing, Casty may Transfer all or any of his Equity Securities (a)

by all of the provisions of this Agreement to the same extent as if such
transferee were such Stockholder, or (b) by will or the laws of descent and
distribution, and further any transferee of Casty may Transfer Equity
Securities to Casty; provided, however, in such event each such transferee
shall be bound by all of the provisions of this Agreement to the same
extent as if such transferee were such Stockholder; and provided, further,
that each such transferee (other than the Subtrust) shall execute an
irrevocable proxy appointing the original Stockholder (except in the case
of death of the original Stockholder) transferring such shares as proxy to
vote all such shares so transferred, such appointment shall be coupled with
an interest, and all stock certificates representing such shares shall bear
a legend providing notice of such appointment of proxy and the restrictions
contained in this Agreement.
(b) The provisions of this Section 3.4 shall terminate upon the
earlier of: (i) a Qualified Public Offering and (ii) the time at which the
Investor

7. The Subtrust acknowledges that it is subject to the provisions of the
Stockholders Agreement (including but not limited to Sections 3.4 and 2.1), to
the same extent as if it were Casty.
8. Casty acknowledges that he shall be subject to Sections 3.4 and 2.1 of
