THREE: The nature of the

FOUR: The total number of shares of all classes of stock which the corporation shall have authority to issue is Thirty-five Million
(35,000,000), consisting of:

A. Twenty-five Million (25,000,000) shares of Common Stock, par value $.0001 each. The Common
Stock of the Company initially shall be divided into two series of stock, consisting of:

(1) Twenty-Three
Million (23,000,000) shares of Class A Voting Common Stock, par value of $.0001 each (hereinafter referred to as Class A Voting Common Stock); and

Upon the effectiveness of this Restated Certificate of Incorporation, each

B. The rights, preferences and privileges of the Class A Voting Common Stock and the Class B Non-Voting Common Stock shall be identical and

to the vote of Common Stock being voted on only by the holders of the Class A Voting Common Stock. Effective as of the closing of any public offering of the Companys Common Stock which is registered with the Securities and Exchange Commission
under the Securities Act of 1933, each outstanding share of Class B Non-Voting Common Stock shall be automatically converted into one fully paid and non-assessable share of Class A Voting Common Stock and thereafter the Common Stock shall cease to

in any resolution or resolutions of the Board of Directors originally fixing the number of shares constituting any series, to increase or decrease (but not below the number of shares of such series then outstanding) the number of shares of any such
series subsequent to the issue of shares of that series.

FIVE: The following provisions are inserted for the management of the business and
the conduct of the affairs of this corporation, and for further definition, limitation and regulation of the powers of this corporation and of its directors and stockholders:

A. The business and affairs of this corporation shall be managed by or under the direction of the Board of Directors. In
addition to the powers and authority expressly conferred upon them by the DGCL or by this Certificate of Incorporation or the Bylaws of this corporation, the directors are hereby empowered to exercise all such powers and do all such acts and things
as may be exercised or done by this corporation.

B. The Board of Directors may adopt, amend or repeal the
Bylaws of this corporation.

C. Election of directors need not be by written ballot.

D. No action required to be taken or which may be taken at any annual or special meeting of stockholders of the Corporation
may be taken without a meeting, and the power of stockholders to consent in writing, without a meeting, to the taking of any such action is specifically denied.

SIX: The officers of this corporation shall be chosen in such a manner, shall hold their offices for such terms and shall carry out such duties as are determined solely by the Board of Directors,
subject to the right of the Board of Directors to remove any officer or officers at any time with or without cause.

SEVEN: No director of this corporation shall be personally liable to this corporation or its stockholders for monetary damages for any breach of fiduciary duty by such a director as a director. Notwithstanding the foregoing sentence,
a director shall be liable to the extent provided by applicable law (i) for any breach of the directors duty of loyalty to this corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional
misconduct or a knowing violation of law, (iii) pursuant to Section 174 of the DGCL or (iv) for any transaction from which such director derived an improper personal benefit. This Article SEVEN is also contained in Article VIII, Section 1 of this
corporations Bylaws. No amendment to or repeal of this Article SEVEN shall apply to or have any effect on the liability or alleged liability of any director of this corporation for or with respect to any acts or omissions of such director
occurring prior to such amendment or repeal. If the DGCL is amended hereafter to further eliminate or limit the personal liability of directors, the liability of a director of this corporation shall be limited or eliminated to the fullest extent
permitted by the DGCL, as amended.

EIGHT: A. Right to Indemnification. Each person who was or is made a party
to or is threatened to be made a party to or is involuntarily involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative (a Proceeding), by reason of the fact that he or she is or was a director
or officer of this corporation, or is or was serving (during his or her tenure as director and/or officer) at the request of this corporation as a director, officer, employee or agent of another corporation or of a partnership, joint venture, trust
or other enterprise, whether the basis of such Proceeding is an alleged action or inaction in an official capacity as a director or officer or in any other capacity while serving as a director or officer, shall be indemnified and held harmless by
this corporation to the fullest extent authorized by the DGCL (or other applicable law), as the same exists or may hereafter be amended, against all expense, liability and loss (including attorneys fees, judgments, fines, ERISA exercise taxes
or penalties and amounts paid or to be paid in settlement) reasonably incurred or suffered by such person in connection with such Proceeding. Such director or officer shall have the right to be paid by this corporation for expenses incurred in
defending any such Proceeding in advance of its final disposition; provided, however, that, if the DGCL (or other applicable law) requires, the payment of such expenses in advance of the final disposition of any such Proceeding shall be made only
upon receipt by this corporation of an undertaking by or on behalf of such director or officer to repay all amounts so advanced if it should be determined ultimately that he or she is not entitled to be indemnified under this Article EIGHT or
otherwise.

B. Right of Claimant to Bring Suit. If a claim under paragraph A of this Article EIGHT is
not paid in full by this corporation within ninety (90) days after a written claim has been received by this corporation,



- 2 -



---

the claimant may at any time thereafter bring suit against this corporation to recover the unpaid amount of the claim, together with interest thereon, and, if successful in whole or in part, the
claimant shall also be entitled to be paid the expense of prosecuting such claim, including reasonable attorneys fees incurred in connection therewith. It shall be a defense to any such action (other than an action brought to enforce a claim
for expenses incurred in defending any Proceeding in advance of its final disposition where the required undertaking, if any is required, has been tendered to this corporation) that the claimant has not met the standards of conduct which make it
permissible under the DGCL (or other applicable law) for this corporation to indemnify the claimant for the amount claimed, but the burden of proving such defense shall be on this corporation. Neither the failure of this corporation (or of its full
Board of Directors, its directors who are not parties to the Proceeding with respect to which indemnification is claimed, its stockholders, or independent legal counsel) to have made a determination prior to the commencement of such action that
indemnification of the claimant is proper in the circumstances because he or she has met the applicable standard of conduct set forth in the DGCL (or other applicable law), nor an actual determination by any such person or persons that such claimant
has not met such applicable standard of conduct, shall be a defense to such action or create a presumption that the claimant has not met the applicable standard of conduct.

C. Non-Exclusivity of Rights. The rights conferred by this Article EIGHT shall not be exclusive of any other right
which any director, officer, representative, employee or other agent may have or hereafter acquire under the DGCL or any other statute, or any provision contained in this corporations Certificate of Incorporation or Bylaws, or any agreement,
or pursuant to a vote of stockholders or disinterested directors, or otherwise.

D. Insurance and Trust
Fund. In furtherance and not in limitation of the powers conferred by statute:

(1) this corporation may purchase and
maintain insurance on behalf of any person who is or was a director, officer, employee or agent of this corporation, or is serving at the request of this corporation as a director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise, against any liability asserted against him or her and incurred by him or her in any such capacity, or arising out of his or her status as such, whether or not this corporation would have the power to
indemnify him or her against such liability under the provisions of law; and

(2) this corporation may create a trust fund,
grant a security interest and/or use other means (including, without limitation, letters of credit, surety bonds and/or other similar arrangements), as well as enter into contracts providing indemnification to the fullest extent permitted by law and
including as part thereof provisions with respect to any or all of the foregoing, to ensure the payment of such amount as may become necessary to effect indemnification as provided therein, or elsewhere.

E. Indemnification of Employees and Agents of this Corporation. This corporation may, to the extent authorized from time to time by
the Board of Directors, grant rights to indemnification, including the right to be paid by this corporation the expenses incurred in defending any Proceeding in advance of its final disposition, to any employee or agent of this corporation to the
fullest extent of the provisions of this Article or otherwise with respect to the indemnification and advancement of expenses of directors and officers of this corporation.

F. Amendment. This Article EIGHT is also contained in Article VIII, Sections 2 through 7, of this corporations Bylaws. Any
repeal or modification of this Article EIGHT shall not change the rights of any officer or director to indemnification with respect to any action or omission occurring prior to such repeal or modification.

NINE: This corporation reserves the right to alter, amend, rescind or repeal any provision contained in this Certificate of
Incorporation, in the manner now or hereafter prescribed by statute, and all rights conferred on stockholders herein are granted subject to this reservation.

TEN: (A) The Board of Directors shall consist of six (6) members. Such set number of
directors may be changed from time to time by resolution of the Board of Directors, except as otherwise provided by law or the Certificate of Incorporation. Any director may resign at any time upon written notice to the Corporation. Directors need
not be stockholders.

(B) The Board of Directors shall be divided into three classes, as nearly equal in numbers as the then
total number of directors constituting the entire Board permits with the term of the office of one class expiring each year. As designated in a written consent of the stockholders dated August 29, 1995, directors of the first class shall be elected
to hold office for a term expiring at the next succeeding annual meeting, directors of the second class shall be elected to hold office for a term expiring at the second succeeding annual meeting and directors of the third class shall be elected to
hold office for a term expiring at the third succeeding annual meeting. Subject to the foregoing, at each annual meeting of stockholders the successors to the class of directors whose term shall then expire shall be elected to hold office for a term
expiring at the third succeeding annual meeting.
