2 Pursuant to Sections 228, 242 and 245 of the General Corporation Laws
of the State of Delaware, this Restated Certificate of Incorporation restates
and integrates and further amends the provisions of the Certificate of

of Delaware. The name of its registered agent at such address is The
Corporation Trust Company.
THIRD: The purpose of this corporation is to engage in any lawful act or
activity for which corporations may be organized under the General Corporation
Law of Delaware.
FOURTH: This corporation is authorized to issue two classes of stock to be
designated, respectively, "Common Stock" and "Preferred Stock." The total
number of shares which the corporation is authorized to issue is 130,000,000
shares. 120,000,000 shares shall be Common Stock, par value $.001 per share,

The Preferred Stock may be issued from time to time in one or more series.
The Board of Directors is authorized to fix the number of shares of any series
of Preferred Stock and to determine the designation of any such series. The
Board of Directors is also authorized to determine and alter the powers, rights,
preferences and privileges and the qualifications, limitations and restrictions
granted to or imposed upon any wholly unissued series of Preferred Stock and
within the limitations or restrictions stated in any resolution or resolutions
of the Board of Directors originally fixing the number of shares constituting

series then outstanding) the number of shares of any series subsequent to the
issue of shares of that series, to determine the designation of any series, and

series shall be so decreased, the share constituting such

decrease shall resume the status that they had prior to the adoption of the
resolution originally fixing the number of shares of such series.
FIFTH: "Qualified Public Offering" as used in this Certificate of
Incorporation shall mean the corporation's initial firm commitment underwritten
public offering pursuant to an effective registration under the Securities Act
of 1933, as amended, covering the offer and sale of Common Stock for the account
of the Corporation to the public. For the management of the business and for
the conduct of the affairs of the corporation, and in further definition,
limitation and regulation of the powers of the corporation, of its directors and
of its stockholders or any class thereof, as the case may be, it is further
provided that, effective upon the closing of a Qualified Public Offering:
1. The management of the business and the conduct of the affairs of the
corporation shall be vested in its Board of Directors. The number of directors
which shall constitute the whole Board of Directors shall be fixed exclusively
by one or more resolutions adopted from time to time by the Board of Directors.
The Board of Directors shall be divided into three classes designated as
Class I, Class II and Class III, respectively. Directors shall be assigned to
each class in accordance with a resolution or resolutions adopted by the Board
of Directors. At the first annual meeting of stockholders following the date
hereof, the term of office of the Class I directors shall expire and Class I
directors shall be elected for a full term of three years. At the second annual
meeting of stockholders following the date hereof, the term of office of the
Class II directors shall expire and Class II directors shall be elected for a
full term of three years. At the third annual meeting of stockholders following
the date hereof, the term of office of the Class III directors shall expire and
Class III directors shall be elected for a full term of three years. At each
succeeding annual meeting of stockholders, directors shall be elected for a full
term of three years to succeed the directors of the class whose terms expire at
such annual meeting. Each holder of voting stock or of any class or series
thereof shall be entitled to cumulative voting rights as to the directors to be
elected by each series or class or the combined classes in accordance with the
provisions of Section 214 of the Delaware General Corporation Law.
Notwithstanding the foregoing provisions of this Article FIFTH, each
director shall serve until his or her successor is duly elected and qualified or
until his or her death, resignation or removal. No decrease in the number of
directors constituting the Board of Directors shall shorten the term of any
incumbent director.
Any vacancies on the Board of Directors resulting from death, resignation,
disqualification, removal, or other causes shall be filled by either (i) the
affirmative vote of the holders of a majority of the voting power of the then-
outstanding shares of voting stock of the corporation entitled to vote generally
in the election of directors (the "Voting Stock") voting together as a single
class; or (ii) by the affirmative vote of a majority of the remaining directors
then in office, even though less than a quorum of the Board of Directors. Newly
created directorships resulting from any increase in the number of directors
shall, unless the Board of Directors determines by resolution that any such
newly created directorship shall be filled by the stockholders, be filled only
by the affirmative vote of the directors then in office, even though less than a
quorum of the Board of Directors. Any director elected in accordance with the
preceding sentence shall hold office for the remainder of the
-2-

full term of the class of directors in which the new directorship was created or
the vacancy occurred and until such director's successor shall have been elected
and qualified.
2. In furtherance and not in limitation of the powers conferred by
statute, the Board of Directors is expressly authorized to make, alter, amend,
or repeal the Bylaws of the corporation.

the following sections of the corporation's Bylaws by the stockholders of this
corporation: 2.3 (Annual Meeting) and 2.4 (Special Meeting).

at an annual or special meeting of the stockholders called in accordance with
the Bylaws.

and of business to be brought by stockholders before any meeting of the
stockholders of the corporation shall be given in the manner provided in the
Bylaws of the corporation.
7. Any director, or the entire Board of Directors, may be removed from
office at any time (i) with cause by the affirmative vote of the holders of at
least a majority of the voting power of all of the then-outstanding shares of
the Voting Stock, voting together as a single class; or (ii) without cause by
the affirmative vote of the holders of at least sixty-six and two-thirds percent
(66-2/3%) of the voting power of all of the then-outstanding shares of the
Voting Stock.
SIXTH: Notwithstanding any other provision in this Certificate of
Incorporation or in any provision of law which might otherwise permit a lesser
vote or no vote, but in addition to any affirmative vote of the holders of any
particular class or series of the Voting Stock required by law, this Certificate
of Incorporation or any Preferred Stock Designation, the affirmative vote of the
holders of at least sixty-six and two-thirds percent (66-2/3%) of the voting
power of all of the then-outstanding shares of the Voting Stock, voting together
as a single class, shall be required to alter, amend or repeal Article FIFTH or
this Article SIXTH.

or employee of the corporation or any predecessor of the corporation or serves
or served at any other enterprise as a director, officer or employee at the
request of the corporation or any predecessor to the corporation.
3. Neither an amendment nor repeal of this Article I, nor the adoption of
any provision of the corporation's Certificate of Incorporation inconsistent
with this Article EIGHTH, shall eliminate or reduce the effect of this Article

or arising or that, but for this Article EIGHTH, would accrue or arise, prior to
such amendment, repeal, or adoption of an inconsistent provision.
