2. Election of
Directors; Voting.



2



---

(a) Election of Directors. The holders of outstanding shares of Convertible
Preferred Stock shall, voting together as a separate class, be entitled to elect one (1) Director of the Corporation. Such Director shall be the candidate receiving the highest number of affirmative votes (with each holder of Convertible
Preferred Stock entitled to cast one vote for or against each candidate with respect to each share of Convertible Preferred Stock held by such holder) of the outstanding shares of Convertible Preferred Stock (the Convertible Preferred Stock
Director Designee), with votes cast against such candidate and votes withheld having no legal effect. The election of the Convertible Preferred Stock Director Designee by the holders of the Convertible Preferred Stock shall occur (i) at
the annual meeting of holders of capital stock, (ii) at any special meeting of holders of capital stock, (iii) at any special meeting of holders of Convertible Preferred Stock called by holders of a majority of the outstanding shares of
Convertible Preferred Stock or (iv) by the unanimous written consent of holders of the outstanding shares of Convertible Preferred Stock. If at any time when any share of Convertible Preferred Stock is outstanding the Convertible Preferred
Stock Director Designee should cease to be a Director for any reason, the vacancy shall only be filled by the vote or written consent of the holders of the outstanding shares of Convertible Preferred Stock, voting together as a separate class, in
the manner and on the basis specified above. The holders of outstanding shares of Convertible Preferred Stock shall also be entitled to vote for all other Directors of the Corporation together with holders of all other shares of the
Corporations outstanding capital stock entitled to vote thereon, voting as a single class, with each outstanding share entitled to the same number of votes specified in Section A.2(b).

(b) Voting Generally. The holder of each share of Convertible Preferred Stock shall be entitled to the number of votes equal to the
largest number of full shares of Common Stock (as defined in Section C of this Article IV) into which each share of Convertible Preferred Stock could be converted pursuant to Section A.6 hereof (other than by means of Section A.6(b)) on the record
date for the vote or for written consent of stockholders, if applicable, multiplied by the number of shares of Convertible Preferred Stock held of record on such date. The holder of each share of Convertible Preferred Stock shall be entitled to
notice of any stockholders meeting in accordance with the by-laws of the Corporation and shall vote with holders of the Common Stock, voting together as single class, upon all matters submitted to a vote of stockholders excluding those matters
required to be submitted to a class or series vote pursuant to the terms hereof (including without limitation Section A.8) or by law. Fractional votes shall not, however, be permitted and any fractional voting rights resulting from the above formula
(after aggregating all shares of Common Stock into which shares of Convertible Preferred Stock held by each holder could be converted) shall be rounded to the nearest whole number (with one-half rounded upward to one).

3. Dividends. The holders of Convertible Preferred Stock shall be entitled to receive, out of funds legally available therefor, cumulative
(non-compounding) dividends on the Convertible Preferred Stock in cash, at the rate per annum of six percent (6%) of the Convertible Base Liquidation Amount (as defined in Section A.4 below), or $.4085 per share of Convertible Preferred Stock
as of the date this Certificate of Incorporation is first filed with the Delaware Secretary of State (the Convertible Cumulative Dividend). Such dividends will accumulate commencing as of the date of issuance of the Convertible Preferred
Stock and shall be cumulative, to the extent unpaid, whether or not they have been declared and whether or not there are profits, surplus or other funds of the Corporation legally available for the payment of dividends. Convertible Cumulative
Dividends shall become due and payable with respect to any share of Convertible Preferred Stock as provided in Sections A.4, A.5, A.6, B.4 and B.5. So long as any shares of



3



---

Convertible Preferred Stock are outstanding and the Convertible Cumulative Dividends have not been paid in full in cash: (a) no dividend whatsoever
shall be paid or declared, and no distribution shall be made, on any capital stock of the Corporation ranking junior to the Convertible Preferred Stock; and, (b) except as permitted by Sections A.8(c)(ii) and (iii), no shares of capital stock
of the Corporation ranking junior to the Convertible Preferred Stock shall be purchased, redeemed or acquired by the Corporation and no monies shall be paid into or set aside or made available for a sinking fund for the purchase, redemption or
acquisition thereof. All numbers relating to the calculation of dividends pursuant to this Section A.3 shall be subject to equitable adjustment in the event of any stock split, combination, reorganization, recapitalization, reclassification or other
similar event involving a change in the Convertible Preferred Stock.

4. Liquidation.

(a) Liquidation Preference. Upon any liquidation, dissolution or winding up of the Corporation and its subsidiaries, whether
voluntary or involuntary (a Liquidation Event), each holder of outstanding shares of Convertible Preferred Stock shall be entitled to be paid out of the assets of the Corporation available for distribution to stockholders, whether such
assets are capital, surplus or earnings, and before any amount shall be paid or distributed to the holders of Common Stock or of any other stock ranking on liquidation junior to the Convertible Preferred Stock, an amount in cash equal to
(i) $6.8091 per share of Convertible Preferred Stock held by such holder (adjusted appropriately for stock splits, stock dividends, recapitalizations and the like with respect to the Convertible Preferred Stock) (the Convertible Base
Liquidation Preference Amount) plus (ii) any accumulated but unpaid dividends to which such holder of outstanding shares of Convertible Preferred Stock is then entitled pursuant to Sections A.3 and A.5(d) hereof, plus (iii) any
interest accrued pursuant to Section A.5(c) to which such holder of Convertible Preferred Stock is entitled (the Convertible Preferred Liquidation Preference Amount); provided, however, that if, upon any Liquidation Event,
the amounts payable with respect to the Convertible Preferred Stock are not paid in full, the holders of the Convertible Preferred Stock shall share ratably in any distribution of assets in proportion to the full respective preferential amounts to
which they are entitled. The provisions of this Section A.4 shall not in any way limit the right of the holders of Convertible Preferred Stock to elect to convert their shares of Convertible Preferred Stock into Redeemable Preferred Stock and Common
Stock pursuant to Section A.6 prior to or in connection with any Liquidation Event.

(b) Notice. Prior to the
occurrence of any Liquidation Event, the Corporation will furnish each holder of Convertible Preferred Stock notice in accordance with Section A.9 hereof, together with a certificate prepared by the chief financial officer of the Corporation
describing in detail the facts of such Liquidation Event, stating in detail the amount(s) per share of Convertible Preferred Stock each holder of Convertible Preferred Stock would receive pursuant to the provisions of Section A.4(a) hereof and
stating in detail the facts upon which such amount was determined.

giving the Corporation and each other holder of Convertible Preferred Stock not less that fifteen (15) days prior written notice, which notice shall set forth the date for such redemption.

(b) Redemption Date; Redemption Price. Upon the election of the holders of not less than sixty-six and two-thirds of the voting
power of the outstanding Convertible Preferred Stock to cause the Corporation to redeem the Convertible Preferred Stock pursuant to Section A.5(a)(i) or (ii), all holders of Convertible Preferred Stock shall be deemed to have elected to cause the
Convertible Preferred Stock to be so redeemed. Any date upon which a redemption shall occur in accordance with Section A.5(a) shall be referred to as a Convertible Preferred Redemption Date. The redemption price for each share of
Convertible Preferred Stock redeemed pursuant to Section A.5 shall be an amount in cash equal to (i) the Convertible Base Liquidation Preference Amount plus (ii) any accumulated but unpaid dividends on such share of Convertible Preferred
Stock pursuant to Sections A.3 and A.5(d) hereof, plus (iii) any interest accrued with respect to such share of Convertible Preferred Stock pursuant to Section A.5(c) (collectively, the Convertible Preferred Redemption Price). The
Convertible Preferred Redemption Price shall be payable in cash in immediately available funds to the respective holders of the Convertible Preferred Stock on the Convertible Preferred Redemption Date and subject to Section A.5(c). Until the full
Convertible Preferred Redemption Price has been paid to such holders for all shares of Convertible Preferred Stock being redeemed: (A) no dividend whatsoever shall be paid or declared, and no distribution shall be made, on any capital stock of
the Corporation; and (B) no shares of capital stock (other than shares of capital stock the repurchase of which is required pursuant to the provisions of ERISA or any like statutory requirement) of the Corporation (other than the Convertible
Preferred Stock in accordance with this Section A.5) shall be purchased, redeemed or acquired by the Corporation and no monies shall be paid into or set aside or made available for a sinking fund for the purchase, redemption or acquisition thereof.

(c) Redemption Prohibited. If, at a Convertible Preferred Redemption Date, the Corporation is prohibited under the

Stock in proportion to the full respective redemption amounts to which they are entitled hereunder to the extent possible and shall redeem the remaining shares to be redeemed as soon as the Corporation is not prohibited from redeeming some or all of
such shares



5



---

under the General Corporation Law of the State of Delaware, subject to the last paragraph of Section A.8. The shares of Convertible Preferred Stock not
redeemed shall remain outstanding and entitled to all of the rights and preferences provided in this Article IV. In the event that the Corporation fails to redeem shares for which redemption is required pursuant to this Section A.5, then during the
period from the applicable Convertible Preferred Redemption Date through the date on which such shares are redeemed, the applicable Convertible Preferred Redemption Price of such shares shall bear interest at the per annum rate of the greater of
(i) 12% or (ii) 5% over the Citibank prime rate published in the Wall Street Journal on such Convertible Preferred Redemption Date, compounded annually; provided, however, that in no event shall such interest exceed the
maximum permitted rate of interest under applicable law (the Maximum Permitted Rate). In the event that fulfillment of any provision hereof results in such rate of interest being in excess of the Maximum Permitted Rate, the obligation to
be fulfilled shall automatically be reduced to eliminate such excess; provided, however, that any subsequent increase in the Maximum Permitted Rate shall be retroactively effective to the applicable Convertible Preferred Redemption
Date.

(d) Dividend After Convertible Preferred Redemption Date. From and after a Convertible Preferred Redemption
Date, no shares of Convertible Preferred Stock subject to redemption shall be entitled to dividends, if any, as contemplated by Section A.3; provided, however, that in the event that shares of Convertible Preferred Stock are unable to

redeemed by the Corporation.

(e) Surrender of Certificates. Upon receipt of the applicable Convertible Preferred
Redemption Price by certified check or wire transfer, each holder of shares of Convertible Preferred Stock to be redeemed shall surrender the certificate or certificates representing such shares to the Corporation, duly assigned or endorsed for
transfer (or accompanied by duly executed stock powers relating thereto), or, in the event the certificate or certificates are lost, stolen or missing, shall deliver an affidavit or agreement satisfactory to the Corporation to indemnify the
Corporation from any loss incurred by it in connection therewith (an Affidavit of Loss) with respect to such certificates at the principal executive office of the Corporation or the office of the transfer agent for the Convertible
Preferred Stock or such office or offices in the continental United States of an agent for redemption as may from time to time be designated by notice to the holders of Convertible Preferred Stock, and each surrendered certificate shall be canceled
and retired; provided, however, that if the holder has exercised its redemption right pursuant to Section A.5(a)(i) or the Corporation is prohibited from redeeming all shares of Convertible Preferred Stock as provided in Section
A.5(c), the holder shall not be required to surrender said certificate(s) to the Corporation until said holder has received a new stock certificate for those shares of Convertible Preferred Stock not so redeemed.

6. Conversion. The holders of the Convertible Preferred Stock shall have the following conversion
rights:

(a) Voluntary Conversion. The holders of shares of Convertible Preferred Stock shall be entitled at any
time, upon the written election of the holder or holders of not less than sixty-six and two-thirds percent in voting power of the outstanding shares of Convertible Preferred Stock, without the payment of any additional consideration, to cause each
(but not less than all) of the outstanding shares of Convertible Preferred Stock to be converted into (i) the number of fully paid and nonassessable shares of Common Stock (as hereinafter defined) which results from dividing the Conversion
Price (as defined in this Section A.6(a)) per share in effect for the Convertible Preferred Stock at the time of conversion into the per share Conversion Value (as defined in this Section A.6(a)) of the Convertible Preferred Stock and (ii) one
(1) fully paid and non-assessable share of Redeemable Preferred Stock per share of Convertible Preferred Stock. Upon the election to so convert in the manner and on the basis specified in the preceding sentence, all holders of the Convertible
Preferred Stock shall be deemed to have elected to voluntarily convert all outstanding shares of Convertible Preferred Stock pursuant to this Section A.6. Upon the filing of this Certificate of Incorporation with the Delaware Secretary of State, the
Conversion Price per share of Convertible Preferred Stock shall be $6.8091, and the per share Conversion Value per share of Convertible Preferred Stock shall be $6.8091. The Conversion Price per share of Convertible

Offerings (as defined in Section A.6(b) below) as provided in Section A.7 hereof. The number of shares of Common Stock into which a share of Convertible Preferred Stock is convertible is hereinafter referred to as the Common Stock Conversion
Rate. The number of shares of Redeemable Preferred Stock into which a share of Convertible Preferred Stock is convertible is hereinafter referred to as the Redeemable Conversion Rate. If the holders of shares of Convertible
Preferred Stock elect to convert the outstanding shares of Convertible Preferred Stock at a time when there are any accumulated but unpaid dividends or other amounts due on or in respect of such shares, such dividends and other amounts shall be paid
in full upon a Liquidation Event (as set forth in Section B.4) or redemption of the Redeemable Preferred Stock (as set forth in Section B.5).

(b) Automatic Conversion Upon QPO or QET. Each share of Convertible Preferred Stock shall automatically be converted, without the payment of any additional consideration, into shares of Common Stock and
Redeemable Preferred Stock as of, and in all cases subject to, the closing of the Corporations first QPO or QET (each as defined below in Section A.6(b)); provided that if a closing of a QPO or QET occurs, all outstanding shares of
Convertible Preferred Stock shall be deemed to have been converted into shares of Common Stock and Redeemable Preferred Stock as provided herein immediately prior to such closing. Any such conversion shall be at the Common Stock Conversion Rate and
Redeemable Conversion Rate in effect upon (and giving effect to) the closing of the QPO or QET, as provided in Section A.6(a). QPO and Qualified Public Offering mean a firm commitment public offering pursuant to an effective

Corporation exceed $20,000,000 at a per share price to public (as set forth in the final prospectus in connection with such public offering) (the Price to Public) equal to at least 1.25 times the Conversion Price, and (ii) either
all shares of Redeemable Preferred Stock which are outstanding or issuable upon such automatic conversion are redeemed immediately upon and as of the closing of such offering or contemporaneously with such offering cash, or, as provided in Section

7



---

Redeemable Preferred Stock in connection with the redemption thereof pursuant to Section B.5(a)(i). QET and Qualified Extraordinary
Transaction mean any of the transactions set forth in subparagraphs (A) through (D) below, provided that (i) at the closing of such transaction the holders of Common Stock that held Convertible Preferred Stock prior to
such automatic conversion upon such QET (the Conversion Holders) receive per share consideration with a value (as determined in Section A.6(c) below with respect to securities, and excluding any amount (exceeding five percent
(5%) of the total consideration paid or payable to the Corporations stockholders) held in escrow or otherwise not actually received as of such closing date) that equals or exceeds three (3) times the Conversion Price should such
transaction close prior to or on December 18, 1998, with such amount increasing in a linear fashion to four (4) times the Conversion Price should such transaction close on or after June 18, 2000, (for example, one of the transactions
set forth in subparagraphs (A) through (D) would be a QET if such per share consideration was three and one-half (3.5) times the Conversion Price and the transaction closed on September 18, 1999, and (ii) such consideration
is in the form of cash and/or unrestricted equity securities of a corporation and such securities have an average monthly trading volume over the four (4) full trading months prior to the closing date of the transaction equal to two
(2) times the aggregate number of such securities to be issued to the Conversion Holders in connection with such closing and such securities trade on either the New York Stock Exchange, the Nasdaq National Market or the American Stock Exchange.
The following transactions (each an Extraordinary Transaction) shall be deemed a QET if the conditions set forth in clauses (i) and (ii) of the immediately preceding sentence are satisfied:

(A) the sale, lease or other disposition of (whether in one transaction or a series of related transactions) all or substantially all of the assets or
business of the Corporation and its subsidiaries;

(B) a merger or consolidation of the Corporation with or into another entity or any
other transaction or series of related transactions, in any such case in connection with or as a result of which the Corporation is not the surviving entity or the owners of the Corporations outstanding equity securities prior to the
transaction or series of related transactions do not own at least a majority of the outstanding equity securities of the surviving, resulting or consolidated entity;

(C) any purchase by any party of shares of capital stock of the Corporation (either through a negotiated stock purchase or a tender for such shares), the effect of which is that such party that did not beneficially
own a majority of the voting power of the outstanding shares of capital stock of the Corporation immediately prior to such purchase beneficially owns at least a majority of such voting power immediately after such purchase; or

(D) the redemption or repurchase of shares representing a majority of the voting power of the outstanding shares of capital stock of the Corporation.

If the holders of shares of Convertible Preferred Stock are required to convert the outstanding shares of Convertible Preferred Stock pursuant to this
Section A.6(b) at a time when there are any accumulated but unpaid dividends or other amounts due on or in respect of such shares, such dividends and other amounts shall be paid in full in cash by the Corporation in connection with such conversion.

---

(c) Valuation of Distribution Securities. In determining whether an Extraordinary
Transaction constitutes a QET, the value of any securities to be delivered to the holders of the Common Stock shall be deemed to be the average of the closing prices or last sales prices, as applicable, of the securities on such exchange or system
over the 30-day period ending three (3) business days prior to the closing.

(d) Procedure for Voluntary Conversion;
Effective Date. Upon election to convert pursuant to Section A.6(a), each holder of Convertible Preferred Stock (i) shall provide written notice of conversion (the Voluntary Conversion Notice) to the Corporation and
(ii) shall surrender the certificate or certificates representing its Convertible Preferred Stock, duly assigned or endorsed for transfer to the Corporation (or accompanied by duly executed stock powers relating thereto), at the principal
executive office of the Corporation or the offices of the transfer agent for the Convertible Preferred Stock or such office or offices in the continental United States of an agent for conversion as may from time to time be designated by notice to
the holders of the Convertible Preferred Stock by the Corporation, or shall deliver an Affidavit of Loss with respect to such certificates. The Voluntary Conversion Notice shall specify (i) the number of shares of Convertible Preferred Stock
held by such holder, (ii) the name or names in which such holder wishes the certificate or certificates for Common Stock and Redeemable Preferred Stock to be issued upon such conversion and (iii) the address to which such holder wishes
delivery to be made of such new certificates to be issued upon such conversion. The issuance by the Corporation of shares of Common Stock and Redeemable Preferred Stock upon a conversion of Convertible Preferred Stock pursuant to Section A.6(a)
hereof shall be effective as of the surrender of the certificate or certificates for the Convertible Preferred Stock to be converted, duly assigned or endorsed for transfer to the Corporation (or accompanied by duly executed stock powers relating
thereto), or as of the delivery of an Affidavit of Loss. Upon surrender of a certificate representing Convertible Preferred Stock for conversion, or delivery of an Affidavit of Loss, the Corporation shall issue and send by hand delivery, by courier
or by first class mail (postage prepaid) to the holder thereof or to such holders designee, at the address designated by such holder, certificates for the number of shares of Common Stock and Redeemable Preferred Stock to which such holder
shall be entitled upon conversion. The issuance of certificates for Common Stock and Redeemable Preferred Stock upon conversion of Convertible Preferred Stock will be made without charge to the holders of such shares for any issuance tax in respect
thereof or other costs incurred by the Corporation in connection with such conversion and the related issuance of such stock. Notwithstanding anything to the contrary set forth in this Section A.6(d), in the event that the holders of shares of
Convertible Preferred Stock elect to convert such shares pursuant to Section A.6(a) in connection with any Liquidation Event, Extraordinary Transaction not constituting a QET or initial public offering not constituting a QPO, (i) the Voluntary
Conversion Notice shall be delivered to the Corporation prior to the effective date of or record date for (as applicable) such Liquidation Event, Extraordinary Transaction or initial public offering and such Voluntary Conversion Notice shall be
effective as of, and shall in all cases be subject to, the occurrence of such Liquidation Event or closing of such Extraordinary Transaction or initial public offering and (ii) if such Liquidation Event, Extraordinary Transaction or initial
public offering occurs, all outstanding shares of Convertible Preferred Stock shall be deemed to have been converted into shares of Common Stock and Redeemable Preferred Stock immediately prior thereto, provided that the Corporation shall make
appropriate provisions (x) for the Common Stock issued upon such conversion to be treated on the same basis as all other Common Stock in such Liquidation Event, Extraordinary Transaction or initial public offering provided that



9



---

the foregoing shall not be construed to provide or require the registration of any shares of Common Stock for sale and (y) for the payment of the
Redeemable Liquidation Preference Amount (as defined in Section B.4) in connection with any Liquidation Event or the redemption of the Redeemable Preferred Stock (issued upon such conversion) upon election of such redemption in connection with any
Extraordinary Transaction or initial public offering, if applicable, as provided herein. In the event of any public offering constituting a QPO or an Extraordinary Transaction constituting a QET, the provisions of Section A.5(e) shall apply.

(e) Procedure for Automatic Conversion. As of, and in all cases subject to, the closing of a QPO or QET (the
Automatic Conversion Date), all outstanding shares of Convertible Preferred Stock shall be converted automatically into shares of Common Stock and Redeemable Preferred Stock at the applicable conversion rates specified in Section A.6(a)
and without any further action by the holders of such shares and whether or not the certificates representing such shares of Convertible Preferred Stock are surrendered to the Corporation or its transfer agent; provided, however, that
all holders of Convertible Preferred Stock shall be given prior written notice of the occurrence of a QPO or QET in accordance with Section A.9 hereof. The Corporation shall not be obligated to issue certificates evidencing the shares of Redeemable
Preferred Stock or Common Stock issuable on the Automatic Conversion Date (or the payment for the shares of Redeemable Preferred Stock which are redeemed immediately after such automatic conversion as provided below and in Section B.5(a)(i)) unless
certificates evidencing such shares of the Convertible Preferred Stock being converted, or an Affidavit or Affidavits of Loss with respect to such certificates, are delivered to the Corporation or its transfer agent. On the Automatic Conversion
Date, all rights with respect to the Convertible Preferred Stock so converted shall terminate, except any of the rights of the holders thereof upon surrender of their certificate or certificates therefor or delivery of an Affidavit of Loss thereof
to receive certificates for the number of shares of Common Stock and Redeemable Preferred Stock into which such Convertible Preferred Stock has been converted (or the payment to which such holder is entitled as provided below and in Section
B.5(a)(i)). Certificates surrendered for conversion shall be endorsed or accompanied by written instrument or instruments of transfer, in form satisfactory to the Corporation, duly executed by the registered holder or by his or its attorney duly
authorized in writing. Upon surrender of such certificates or Affidavit of Loss the Corporation shall issue and deliver to such holder, promptly (and in any event in such time as is sufficient to enable such holder to participate in such QPO or QET)
at such office and in its name as shown on such surrendered certificate or certificates, a certificate or certificates for the number of shares of Common Stock and number of shares of Redeemable Preferred Stock into which the shares of the
Convertible Preferred Stock surrendered were convertible on the Automatic Conversion Date. Notwithstanding anything to the contrary set forth in this Section A.6(e), the Corporation may deliver, in lieu of certificates for Redeemable Preferred
Stock, a payment in an amount and form determined pursuant to Section B.5(b) hereof on account of the redemption of such Redeemable Preferred Stock, and upon such payment the Redeemable Preferred Stock into which such Convertible Preferred Stock
would have been converted shall be deemed to have been issued and redeemed by the Corporation.

(f) Reservation of Stock
Issuable Upon Conversion. The Corporation shall at all times reserve and keep available out of its authorized but unissued shares of Common Stock and Redeemable Preferred Stock solely for the purpose of effecting the conversion of the shares of
Convertible Preferred Stock such number of its shares of Common Stock and Redeemable Preferred



10



---

Stock as shall from time to time be sufficient to effect the conversion of all outstanding shares of Convertible Preferred Stock; and if at any time the
number of authorized but unissued shares of Common Stock and Redeemable Preferred Stock shall not be sufficient to effect the conversion of all then outstanding shares of Convertible Preferred Stock, the Corporation will take such corporate action
as may be necessary to increase its authorized but unissued shares of Common Stock and Redeemable Preferred Stock to such number of shares as shall be sufficient for such purpose.

(g) No Closing of Transfer Books. The Corporation shall not close its books against the transfer of shares of Convertible Preferred
Stock in any manner which would interfere with the timely conversion of any shares of Convertible Preferred Stock.

7. Adjustments.
The Conversion Price and Conversion Value in effect from time to time shall be subject to adjustment from and after June 18, 1997, and regardless of whether any shares of Convertible Preferred Stock are then issued and outstanding as follows:

(a) Adjustments to Conversion Price.

(i) Stock Dividends, Subdivisions and Combinations. Upon the issuance of additional shares of Common Stock as a dividend or other
distribution on outstanding Common Stock, the subdivision of outstanding shares of Common Stock into a greater number of shares of Common Stock, or the combination of outstanding shares of Common Stock into a smaller number of shares of the Common
Stock, the Conversion Price shall, simultaneously with the happening of such dividend, subdivision or split be adjusted by multiplying the then effective Conversion Price by a fraction, the numerator of which shall be the number of shares of Common
Stock outstanding immediately prior to such event and the denominator of which shall be the number of shares of Common Stock outstanding immediately after such event. An adjustment made pursuant to this Section A.7(a)(i) shall be given effect, upon
payment of such a dividend or distribution, as of the record date for the determination of stockholders entitled to receive such dividend or distribution (on a retroactive basis) and in the case of a subdivision or combination shall become effective
immediately as of the effective date thereof.

(ii) Sale of Common Stock. In the event the Corporation shall at any
time, or from time to time, issue, sell or exchange any shares of Common Stock including shares held in the Corporations treasury but excluding up to an aggregate 3,735,479 shares of Common Stock (as appropriately adjusted for stock splits,
stock dividends and the like) issued to officers, Directors, employees of, or consultants, advisors, independent contractors to the Corporation or the Corporations Employee Stock Ownership Plan (the ESOP) (collectively,
Eligible Employees) pursuant to the Corporations 1995 Stock Option Plan, 1997 Stock Option Plan or ESOP (collectively, the Plans) or upon the exercise of options or other rights issued to such Eligible Employees
pursuant to the Plans (collectively, the Excluded Shares), for a consideration per share less than the Conversion Price in effect immediately prior to the issuance, sale or exchange of such shares, then, and thereafter successively upon
each such issuance, sale or exchange, the Conversion Price in effect immediately prior to the issuance, sale or exchange of such shares shall forthwith be reduced to an amount determined by multiplying such Conversion Price by a fraction:



| | (A) | the numerator of which shall be (X) the number of shares of Common Stock of all classes outstanding immediately prior to the issuance of such additional shares of Common Stock
(excluding treasury shares but including all shares of Common Stock issuable upon conversion or exercise of any outstanding Convertible Preferred Stock, options, warrants, rights or convertible securities), plus (Y) the number of shares of
Common Stock which the net aggregate consideration received by the Corporation for the total number of such additional shares of Common Stock so issued would purchase at the Conversion Price (prior to adjustment), and

| | (B) | the denominator of which shall be (X) the number of shares of Common Stock of all classes outstanding immediately prior to the issuance of such additional shares of Common
Stock (excluding treasury shares but including all shares of Common Stock issuable upon conversion or exercise of any outstanding Convertible Preferred Stock, options, warrants, rights or convertible securities), plus (Y) the number of such
additional shares of Common Stock so issued.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

(iii) Sale of Options, Rights or Convertible Securities.
In the event the Corporation shall at any time or from time to time, issue options, warrants or rights to subscribe for shares of Common Stock, or issue any securities convertible into or exchangeable for shares of Common Stock (other than any
options or warrants for Excluded Shares), for a consideration per share (determined by dividing the Net Aggregate Consideration (as determined below) by the aggregate number of shares of Common Stock that would be issued if all such options,
warrants, rights or convertible securities were exercised or converted to the fullest extent permitted by their terms) less than the Conversion Price in effect immediately prior to the issuance of such options or rights or convertible or
exchangeable securities, the Conversion Price in effect immediately prior to the issuance of such options, warrants or rights or securities shall be reduced to an amount determined by multiplying such Conversion Price by a fraction:



| | (A) | the numerator of which shall be (X) the number of shares of Common Stock of all classes outstanding immediately prior to the issuance of such options, rights or convertible
securities (excluding treasury shares but including all shares of Common Stock issuable upon conversion or exercise of any outstanding Convertible Preferred Stock, options, warrants, rights or convertible securities), plus (Y) the number of
shares of Common Stock which the total amount of consideration received by the Corporation for the issuance of such options, warrants, rights or convertible securities plus the minimum amount set forth in the terms of such security as payable to the
Corporation upon the exercise or conversion thereof (the Net Aggregate Consideration) would purchase at the Conversion Price prior to adjustment, and

| | (B) | the denominator of which shall be (X) the number of shares of Common Stock of all classes outstanding immediately prior to the issuance of such options, warrants, rights or
convertible securities (excluding treasury shares but including all shares of Common Stock issuable upon conversion or exercise of any outstanding Convertible Preferred Stock, options, warrants, rights or convertible securities), plus (Y) the
aggregate number of shares of Common Stock that would be issued if all such options, warrants, rights or convertible securities were exercised or converted.
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

(iv) Expiration or Change in Price. If the consideration per share provided for in any options or rights to subscribe for shares of
Common Stock or any securities exchangeable for or convertible into shares of Common Stock changes at any time, the Conversion Price in effect at the time of such change shall be readjusted to the Conversion Price which would have been in effect at
such time had such options or convertible securities provided for such changed consideration per share (determined as provided in Section A.7(a)(iii) hereof), at the time initially granted, issued or sold; provided, that such adjustment of
the Conversion Price will be made only as and to the extent that the Conversion Price effective upon such adjustment remains less than or equal to the Conversion Price that would be in effect if such options, rights or securities had not been
issued. No adjustment of the Conversion Price shall be made under this Section A.7(a) upon the issuance of any additional shares of Common Stock which are issued pursuant to the exercise of any warrants, options or other subscription or purchase
rights or pursuant to the exercise of any conversion or exchange rights in any convertible securities if an adjustment shall previously have been made upon the issuance of such warrants, options or other rights. Any adjustment of the Conversion
Price shall be disregarded if, as, and when the rights to acquire shares of Common Stock upon exercise or conversion of the warrants, options, rights or convertible securities which gave rise to such adjustment expire or are canceled without having
been exercised, so that the Conversion Price effective immediately upon such cancellation or expiration shall be equal to the Conversion Price in effect at the time of the issuance of the expired or canceled warrants, options, rights or convertible
securities, with such additional adjustments as would have been made to that Conversion Price had the expired or canceled warrants, options, rights or convertible securities not been issued.

(b) Adjustment to Conversion Value upon Certain QPOs. As set forth below, upon a QPO in which the Price to Public (as defined in
Section A.6(b)) is 1.25 times or greater but less than two (2) times the Conversion Price, for the purpose of determining the number of shares of Common Stock to be issued upon conversion of the Convertible Preferred Stock in connection
therewith, the Conversion Value shall be adjusted prior to the closing and conversion by multiplying the Conversion Value then in effect by the applicable Conversion Value Multiplier set forth below. The Conversion Value Multiplier is determined
according to (i) the closing date of such offering and (ii) the Price to Public expressed as a multiple of the Conversion Price. The Conversion Value Multiplier with respect to any multiple of the Conversion Price between any of the data
points in any column below shall be determined by linear interpolation (for example, given a QPO on July 1, 1997 with a Price to Public equal to 1.625 times the Conversion Price, the Conversion Value Multiplier would be 1.0355).

(c) Other Adjustments. In the event the Corporation shall make or issue, or
fix a record date for the determination of holders of Common Stock entitled to receive, a dividend or other distribution payable in securities of the Corporation other than shares of Common Stock, then and in each such event lawful and adequate
provision shall be made so that the holders of Convertible Preferred Stock shall receive upon conversion thereof in addition to the number of shares of Common Stock receivable thereupon, the number of securities of the Corporation which they would
have received had their Convertible Preferred Stock been converted into Common Stock and Redeemable Preferred Stock on the date of such event and had they thereafter, during the period from the date of such event to and including the date of
conversion, retained such securities receivable by them as aforesaid during such period, giving application to all adjustments called for during such period under this Section A.7 as applied to such distributed securities.

If the Common Stock issuable upon the conversion of the Convertible Preferred Stock shall be changed into the same or different number of shares of any
class or classes of stock, whether by reclassification or otherwise (other than a subdivision or combination of shares or stock dividend provided for above, or a reorganization, merger, consolidation or sale of assets provided for elsewhere in this
Section A.7), then and in each such event the holder of each share of Convertible Preferred Stock shall have the right thereafter to convert such share into the kind and amount of shares of stock and other securities and property receivable upon
such reorganization, reclassification or other change, by holders of the number of shares of Common Stock into which such shares of Convertible Preferred Stock might have been converted immediately prior to such reorganization, reclassification or
change, all subject to further adjustment as provided herein.

(d) Mergers and Other Reorganizations. Unless such
transaction is a QET (in which case Section A.6(b) shall apply and this subsection shall not apply), if at any time or from time to time there shall be a capital reorganization of the Common Stock (other than a subdivision, combination,
reclassification or exchange of shares provided for elsewhere in this Section A.7) or a merger or consolidation of the Corporation with or into another Corporation or the sale of all or substantially all of the Corporations properties and
assets to any other person, then, as a part of and as a condition to the effectiveness of such reorganization, merger, consolidation or sale, lawful and adequate provision shall be made so that the holders of the Convertible Preferred Stock shall
thereafter be entitled to receive upon conversion of the Convertible Preferred Stock the number of shares of stock or other securities or property of the Corporation or of the successor Corporation resulting from such merger or consolidation or
sale, to which a holder of Common Stock deliverable upon conversion would have been entitled on such capital



14



---

reorganization, merger, consolidation, or sale. In any such case, appropriate provisions shall be made with respect to the rights of the holders of the
Convertible Preferred Stock after the reorganization, merger, consolidation or sale to the end that the provisions of this Section A.7 (including without limitation provisions for adjustment of the Conversion Price and the number of shares
purchasable upon conversion of the Convertible Preferred Stock) shall thereafter be applicable, as nearly as may be, with respect to any shares of stock, securities or assets to be deliverable thereafter upon the conversion of the Convertible
Preferred Stock.

(e) All calculations under this Section A.7 shall be made to the nearest cent or to the nearest one
hundredth (1/100) of a share, as the case may be.

(f) Upon the occurrence of each adjustment or readjustment pursuant
to this Section A.7, the Corporation at its expense shall promptly compute such adjustment or readjustment in accordance with the terms hereof and prepare and furnish to each holder of Convertible Preferred Stock a certificate setting forth such
adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based. The Corporation shall, upon written request at any time of any holder of Convertible Preferred Stock, furnish or cause to be furnished to
such holder a like certificate setting forth (i) such adjustments and readjustments, (ii) the Conversion Prices before and after such adjustment or readjustment, and (iii) the number of shares of Common Stock and Redeemable Preferred
Stock and the amount, if any, of other property which at the time would be received upon the conversion of such holders shares of Convertible Preferred Stock.

8. Covenants. So long as any shares of Convertible Preferred Stock (or Redeemable Preferred Stock, as applicable) shall be outstanding, the Corporation shall not, without first having provided the written
notice of such proposed action to each holder of outstanding shares of Convertible Preferred Stock (or Redeemable Preferred Stock, as applicable) and having obtained the affirmative vote or written consent of the holders of not less than sixty-six
and two-thirds percent in voting power of the outstanding shares of Convertible Preferred Stock (or Redeemable Preferred Stock, as applicable), voting as a single class, with each share of Convertible Preferred Stock (or Redeemable Preferred Stock,
as applicable) entitling the holder thereof to one vote per share of Convertible Preferred Stock held by such holder:

(a)
unless such transaction is a QET, effect (I) any Extraordinary Transaction or other sale or transfer of all or substantially all of the properties and assets of any subsidiary of the Corporation, (II) any recapitalization of the Corporation or
(III) any other transaction or series of related transactions in which more than 50% of the voting power of the Corporation is transferred;

(b) dissolve, liquidate or wind up its operations;

(c) directly or indirectly redeem,
purchase, or otherwise acquire for consideration any shares of its Common Stock or any other class of its capital stock except for (i) redemption of Convertible Preferred Stock or Redeemable Preferred Stock pursuant to and as provided in this
Certificate of Incorporation, (ii) repurchase of up to 1,101,471 shares of Common Stock from the stockholders of the Company pursuant to a Repurchase Agreement dated June 18, 1997, or (iii) redemption or repurchase of Common Stock
issued pursuant to the Plans from Eligible Employees (as defined in Section A.7(a)(ii)) pursuant to an agreement containing vesting and/or repurchase provisions approved by the Board of Directors of the Corporation or a committee thereof;

(d) propose or adopt any amendment to this Article IV, or any other amendment to this
Certificate of Incorporation or the Corporations By-Laws that eliminates, amends or restricts or otherwise adversely affects the rights and preferences of the Convertible Preferred Stock or the Redeemable Preferred Stock, or increase the
authorized shares of Convertible Preferred Stock or Redeemable Preferred Stock;

(e) declare or make dividend payments on
any shares of Common Stock or any other class of the Corporations capital stock;

(f) create, or obligate itself to
create, any class or series of shares having preference over or being on a parity with the Convertible Preferred Stock or the Redeemable Preferred Stock;

(g) increase the size of the Board of Directors to more than seven (7) members; or

(h)
except as provided in the Corporations 1997 Management Bonus Plan, pay any bonuses to the Corporations executive officers unless any such bonus shall have been unanimously approved by the compensation committee of the Board of Directors.

Further, the Corporation and each subsidiary of the Corporation shall not, by amendment of this Certificate of Incorporation or through
any Extraordinary Transaction or other reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be
observed or performed hereunder by the Corporation and each subsidiary of the Corporation but shall at all times in good faith assist in the carrying out of all the provisions of this Article IV and in the taking of all such action as may be
necessary or appropriate in order to protect the rights of the holders of the Convertible Preferred Stock and the Redeemable Preferred Stock set forth in this Certificate against impairment. Any successor to the Corporation or any subsidiary of the
Corporation shall agree, as a condition to such succession, to carry out and observe the obligations of the Corporation hereunder with respect to the Convertible Preferred Stock and the Redeemable Preferred Stock.

9. Notice

(a) Liquidation Events, Extraordinary Transactions, Etc. In the event (i) the Corporation establishes a record date to
determine the holders of any class of securities who are entitled to receive any dividend or other distribution or who are entitled to vote at a meeting (or by written consent) in connection with any of the transactions identified in clause
(ii) hereof, or (ii) any Liquidation Event (as defined in Section A.4), any Extraordinary Transaction, QET or QPO (each as defined in Section A.6) or any other public offering becomes reasonably likely to occur, the Corporation shall mail
or cause to be mailed by first class mail (postage prepaid) to each holder of Convertible Preferred Stock (or each holder of Redeemable Preferred Stock, as applicable) at least twenty (20) business days prior to such record date specified
therein or the expected effective date of any such transaction, whichever is earlier, a notice specifying (A) the date of such record date for the purpose of such dividend or distribution or meeting or consent and a description of such dividend
or distribution or the action to be taken at such meeting or by such consent, (B) the date on which any such Liquidation Event, Extraordinary Transaction, QET, QPO or other public offering is expected to become effective, and (C) the date
on which the books of the Corporation shall close or a record shall be taken with respect to any such event.

(b) Waiver
of Notice. The holder or holders of not less than sixty-six and two-thirds percent in voting power of the outstanding shares of Convertible Preferred Stock (or Redeemable Preferred Stock, as applicable) may, at any time upon written notice to
the Corporation, waive any notice provisions specified herein for the benefit of such holders, and any such waiver shall be binding upon the holders of all such securities.

(c) General. In the event that the Corporation provides any notice, report or statement to any holder of Common Stock, the
Corporation shall at the same time provide a copy of any such notice, report or statement to each holder of outstanding shares of Convertible Preferred Stock (or Redeemable Preferred Stock, as applicable).

10. No Reissuance of Convertible Preferred Stock. No share or shares of Convertible Preferred Stock acquired by the Corporation by reason of
redemption, purchase, conversion or otherwise shall be reissued, and all such shares shall be canceled, retired and eliminated from the shares which the Corporation shall be authorized to issue.

B. REDEEMABLE PREFERRED STOCK

1.
Designation; Ranking. A total of 2,202,942 shares of the Corporations Preferred Stock shall be designated as Redeemable Preferred Stock, $.01 par value per share (the Redeemable Preferred Stock).



17



---

2. Election of Directors; Voting.

(a) Election of Directors. The holders of outstanding shares of Redeemable Preferred Stock shall, voting together as a separate
class, be entitled to elect one (1) Director. Such Director shall be the candidate receiving the highest number of affirmative votes (with each holder of Redeemable Preferred Stock entitled to cast one vote for or against each candidate with
respect to each share of Redeemable Preferred Stock held by such holder) of the outstanding shares of Redeemable Preferred Stock (the Redeemable Preferred Stock Director Designee), with votes cast against such candidate and votes
withheld having no legal effect. The election of the Redeemable Preferred Stock Director Designee by the holders of the Redeemable Preferred Stock shall occur (i) at the annual meeting of holders of capital stock, (ii) at any special
meeting of holders of capital stock, (iii) at any special meeting of holders of Redeemable Preferred Stock called by holders of a majority of the outstanding shares of Redeemable Preferred Stock or (iv) by the unanimous written consent of
holders of the outstanding shares of Redeemable Preferred Stock. Upon conversion of the Convertible Preferred Stock, the Convertible Preferred Stock Director Designee then serving on the Corporations board of directors shall continue in such
capacity as the Redeemable Preferred Stock Designee. If at any time when any share of Redeemable Preferred Stock is outstanding the Redeemable Preferred Stock Director Designee should cease to be a Director for any reason, the vacancy shall only be
filled by the vote or written consent of holders of the outstanding shares of Redeemable Preferred Stock, voting together as a separate class, in the manner and on the basis specified above.

(b) Voting Generally. Except as set forth above with respect to the election of the Redeemable Preferred Stock Director Designee,
the holders of Redeemable Preferred Stock shall not be entitled to vote on any matters except to the extent otherwise required under the General Corporation Law of the State of Delaware.

3. Dividends. The holders of outstanding shares of Redeemable Preferred Stock shall be entitled to receive, out of any funds legally available
therefor, cumulative (non-compounding) dividends on the Redeemable Preferred Stock in cash, at the rate per annum of three percent (3%) of $6.8091 per share (adjusted appropriately for stock splits, stock dividends, recapitalizations and the
like with respect to the Redeemable Preferred Stock), or $.2043 per share of Redeemable Preferred Stock as of the date this Certificate of Incorporation is first filed with the Delaware Secretary of State (a Redeemable Cumulative
Dividend). Such dividends will accrue commencing as of the date of issuance of the Redeemable Preferred Stock and be cumulative, to the extent unpaid, whether or not they have been declared and whether or not there are profits, surplus or
other funds of the Corporation legally available for the payment of dividends. Redeemable Cumulative Dividends shall become due and payable with respect to any share of Redeemable Preferred Stock as provided in Section B.4 and Section B.5. So long
as any shares of Redeemable Preferred Stock are outstanding and the Redeemable Cumulative Dividends have not been paid in full in cash: (A) no dividend whatsoever shall be paid or declared, and no distribution shall be made, on any capital
stock of the Corporation ranking junior to the Redeemable Preferred Stock; and (B) no shares of capital stock of the Corporation ranking junior to the Redeemable Preferred Stock shall be purchased, redeemed or acquired by the Corporation and no
monies shall be paid into or set aside or made available for a sinking fund for the purchase, redemption or



18



---

acquisition thereof. All numbers relating to the calculation of dividends pursuant to this Section B.3 shall be subject to equitable adjustment in the event
of any stock split, combination, reorganization, recapitalization, reclassification or other similar event involving a change in the Redeemable Preferred Stock.

4. Liquidation.

(a) Upon any Liquidation Event, each holder of outstanding shares of
Redeemable Preferred Stock shall be entitled to be paid out of the assets of the Corporation available for distribution to stockholders, whether such assets are capital, surplus, or earnings as follows, and before any amount shall be paid or
distributed to the holders of Common Stock or of any other stock ranking on liquidation junior to the Redeemable Preferred Stock, an amount in cash equal to the sum of (i) the Redeemable Base Liquidation Amount (as determined in Section B.4(b)
below) multiplied by the number of shares of Redeemable Preferred Stock held by such holder, plus (ii) any accumulated but unpaid dividends to which such holder of outstanding shares of Redeemable Preferred Stock is entitled pursuant to Section
B.3 and B.5(d) hereof, plus (iii) any interest accrued pursuant to Section B.5(c) to which such holder of outstanding shares of Redeemable Preferred Stock is entitled, plus (iv) any accumulated but unpaid dividends or other amounts due on
or in respect of the shares of Convertible Preferred Stock held by such holder prior to the conversion of such Convertible Preferred Stock (the Redeemable Liquidation Preference Amount); provided, however, that if, upon any
Liquidation Event, the amounts payable with respect to the Redeemable Preferred Stock are not paid in full, the holders of the Redeemable Preferred Stock shall share ratably in any distribution of assets in proportion to the full respective
preferential amounts to which they are entitled.

(b) The per share Redeemable Base Liquidation Amount shall be
determined according to (i) the closing date of the Liquidation Event, QPO, QET, Extraordinary Transaction or public offering (each a Measurement Event) and (ii) (A) in connection with a QPO or public offering, the Price
to Public (as defined in Section A.6(b)) expressed as a multiple of the Conversion Price or, (B) in connection with a Liquidation Event, QET, or Extraordinary Transaction, the value (as determined in Section B.4(c) below, and excluding any
amount held in escrow or otherwise not actually received as of such closing date), expressed as a multiple of the Conversion Price, of the cash, securities or other consideration distributed, paid or delivered at closing with respect to each share
of Common Stock. The following schedule sets forth the Redeemable Base Liquidation Amount at various data points. Between data points, the Redeemable Base Liquidation Amount reduces in a linear fashion corresponding to linear increases in either
time (with a day being the smallest unit of measurement), multiple or both. For example, if on June 18, 1999 the Price to Public or per share value of such consideration were 2.5 times the Conversion Price, the Redeemable Base Liquidation
Amount per share would be $5.6743. By way of further example, if on December 18, 1998 the Price to Public or per share value of such consideration were 3.5 times the Conversion Price, the Redeemable Base Liquidation Amount per share would be
$0.00, and each holder would be entitled to receive the amounts due under clauses (ii) through (iv) of Section B.4(a) above.

(c) Valuation of Distribution Securities. For purposes of determining the
Redeemable Base Liquidation Amount, any securities or other consideration to be delivered to the holders of the Common Stock upon completion of any Measurement Event shall be valued as follows:

(i) If traded on a nationally recognized securities exchange or inter- dealer quotation system, the value shall be deemed to be the
average of the closing prices of the securities on such exchange or system over the 30-day period ending three (3) business days prior to the closing;

(ii) If traded over-the-counter, the value shall be deemed to be the average of the closing bid prices over the 30-day period ending three (3) business days prior to the closing; and

(iii) If there is no active public market, the value shall be the fair market value thereof, as mutually determined by the Corporation and
the holders of not less than sixty-six and two-thirds percent in voting power of the outstanding shares of Convertible Preferred Stock, provided that if the Corporation and the holders of sixty-six and two-thirds percent in voting power of the
outstanding shares of Convertible Preferred Stock are unable to reach agreement, then by independent appraisal by an investment banker hired and paid by the Corporation, but reasonably acceptable to the holders of sixty-six and two-thirds percent in
voting power of the outstanding shares of Convertible Preferred Stock.

5. Redemption.

(a) Redemption Events.

(i) Automatic. Immediately upon and as of, and in all cases subject to, the closing of a QPO or QET, the Corporation shall redeem all (and not less than all) of the outstanding shares of Redeemable Preferred
Stock at the Redemption Price specified in Section B.5(b); provided that if the Corporation shall receive the proceeds from such QPO or QET in next-day available funds, such redemption shall occur on the first business day following such closing.



20



---

(ii) Optional.



| | (A) | Upon Certain Transactions. Upon the election of the holder or holders of not less than sixty-six and two-thirds percent in voting power of the outstanding Redeemable
Preferred Stock (or Convertible Preferred Stock, as applicable, proposing to convert the same in order to effect a redemption of the Redeemable Preferred Stock received upon such conversion hereunder), the Corporation shall redeem all (and not less
than all, other than pursuant to Section B.5(c) below) of the outstanding shares of Redeemable Preferred Stock upon the occurrence of an Extraordinary Transaction (as defined in Section A.6) not constituting a QET or, other than a public offering
initiated by the holders of Convertible Preferred Stock or Redeemable Preferred stock, a public offering not constituting a QPO.
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (B) | Notice. An election pursuant to subparagraph (A) of this Section B.5(a)(ii) shall be made by such holders giving the Corporation and each other holder of Redeemable
Preferred Stock (or Convertible Preferred Stock, as applicable) not less that five (5) days prior written notice, which notice shall set forth the date for such redemption.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

(b) Redemption Date; Redemption Price. Upon the election of the holders of not less than sixty-six and two-thirds percent in voting
power of the outstanding Redeemable Preferred Stock to cause the Corporation to redeem the Redeemable Preferred Stock pursuant to Section B.5(a)(ii), all holders of Redeemable Preferred Stock shall be deemed to have elected to cause the Redeemable
Preferred Stock to be so redeemed. Any date upon which a redemption shall occur in accordance with Section B.5(a) shall be referred to as a Redemption Date. The redemption price for each share of Redeemable Preferred Stock redeemed
pursuant to this Section B.5 shall be the sum of (i) the Redeemable Base Liquidation Amount (as set forth in Section B.4(b) above), plus (ii) any accumulated but unpaid dividends on such share of Redeemable Preferred Stock pursuant to
Section B.3 and Section B.5(d) hereof, plus (iii) any interest accrued with respect to such share of Convertible Preferred Stock pursuant to Section B.5(c), plus (iv) any accumulated but unpaid dividends or other amounts due on or in
respect of the share of Convertible Preferred Stock from which such share of Redeemable Preferred Stock was converted (the Redemption Price). Except as holders of sixty-six and two-thirds percent of the Redeemable Preferred Stock shall
otherwise agree, the Redemption Price shall be payable in cash in immediately available funds to the respective holders of the Redeemable Preferred Stock on the Redemption Date; provided, however, that upon a QPO in which the Price to
Public (as defined in Section A.6(b)) is 1.25 times or greater but less than two (2) times the Conversion Price, the portion of the Redemption Price representing the Redeemable Base Liquidation Amount shall be payable in a combination of cash
and promissory notes, which promissory notes will have a



21



---

maturity date equal to one year after the Redemption Date, shall bear interest at the per annum rate equal to the greater of (x) 12% or (y) 5% over
the Citibank prime rate published in the Wall Street Journal on the Redemption Date and shall contain other customary terms and provisions (Promissory Notes), as set forth below, and the remaining portions of the Redemption Price set
forth in clause (ii) through (iv) of this Section B.5(b) shall be paid in cash. The per share amount of cash and amount of Promissory Notes is determined according to (i) the closing date of such offering and (ii) the Price to
Public expressed as a multiple of the Conversion Price. The per share amount of cash and amount of Promissory Notes with respect to any multiple of the Conversion Price between any of the data points in any column below shall be determined by linear
interpolation (for example, given a QPO on July 1, 1997 with a Price to Public equal to 1.625 times the Conversion Price, the Redemption Price shall be payable $6.2417 in cash and $.5674 in Promissory Notes).

Until the full Redemption Price, including any interest thereon, has been paid to such holders in
cash (or cash and Promissory Notes, as provided above) for all shares of Redeemable Preferred Stock redeemed as of the applicable Redemption Date: (A) no dividend whatsoever shall be paid or declared, and no distribution shall be made, on any
capital stock of the Corporation; and (B) no shares of capital stock of the Corporation (other than the Redeemable Preferred Stock in accordance with this Section B.5 or shares of capital stock the repurchase of which is required pursuant to
the provisions of ERISA or any like statutory requirement) shall be purchased, redeemed or acquired by the Corporation and no monies shall be paid into or set aside or made available for a sinking fund for the purchase, redemption or acquisition
thereof.

(c) Redemption Prohibited. If, at a Redemption Date, the Corporation is prohibited under the General
Corporation Law of the State of Delaware from redeeming all shares of Redeemable Preferred Stock for which redemption is required hereunder, then it shall redeem such shares on a pro-rata basis among the holders of Redeemable Preferred Stock in
proportion to the full respective redemption amounts to which they are entitled hereunder to the extent possible and shall redeem the remaining shares to be redeemed as soon as the Corporation is not prohibited from redeeming some or all of such
shares under the General Corporation Law of the State of Delaware, subject to the last paragraph of Section A.8. The shares of Redeemable Preferred Stock not redeemed shall remain outstanding and entitled to all of the rights and preferences
provided in this Article IV. In the event that the Corporation fails to redeem shares for which redemption is required pursuant to Section B.5, then during the period from the applicable Redemption Date through the date on which such shares are
redeemed, the applicable Redemption Price of such shares plus additional dividends that accumulate in respect of such shares under Section B.5(d) shall bear interest



22



---

at the per annum rate of the greater of (i) 12% or (ii) 5% over the Citibank prime rate published in the Wall Street Journal on such Convertible
Preferred Redemption Date, compounded annually; provided, however, that in no event shall such interest exceed the maximum permitted rate of interest under applicable law (the Maximum Permitted Rate). In the event that
fulfillment of any provision hereof results in such rate of interest being in excess of the Maximum Permitted Rate, the obligation to be fulfilled shall automatically be reduced to eliminate such excess; provided, however, that any
subsequent increase in the Maximum Permitted Rate shall be retroactively effective to the applicable Preferred Redemption Date.

(d) Dividend After Redemption Date. From and after a Redemption Date, no shares of Redeemable Preferred Stock subject to redemption shall be entitled to any further dividends pursuant to Section B.3 hereof; provided,
however, that in the event that shares of Redeemable Preferred Stock are unable to be redeemed and continue to be outstanding in accordance with Section B.5(c), such shares shall continue to be entitled to dividends and interest thereon as
provided in Sections B.3 and B.5(c) until the date on which such shares are actually redeemed by the Corporation.

(e)
Surrender of Certificates. Upon receipt of the applicable Redemption Price by certified check or wire transfer, each holder of shares of Redeemable Preferred Stock to be redeemed shall surrender the certificate or certificates representing
such shares to the Corporation, duly assigned or endorsed for transfer (or accompanied by duly executed stock powers relating thereto), or shall deliver an Affidavit of Loss with respect to such certificates at the principal executive office of the
Corporation or the office of the transfer agent for the Redeemable Preferred Stock or such office or offices in the continental United States of an agent for redemption as may from time to time be designated by notice to the holders of Redeemable
Preferred Stock (or the holders of Convertible Preferred Stock, as applicable), and each surrendered certificate shall be canceled and retired; provided, however, that if the holder has exercised its redemption right pursuant to
Section B.5(a)(ii)(A), the holder shall not be required to surrender said certificate(s) to the Corporation until said holder has received a new stock certificate for those shares of Redeemable Preferred Stock not so redeemed.

6. Notice. In the event that the Corporation provides or is required to provide notice to any holder of Convertible Preferred Stock or any holder
of Common Stock in accordance with the provisions of this Certificate of Incorporation (including the provisions of Section A.9) and/or the Corporations by-laws, the Corporation shall at the same time provide a copy of any such notice to each
holder of outstanding shares of Redeemable Preferred Stock.

7. No Reissuance of Redeemable Preferred Stock. No share or shares of
Redeemable Preferred Stock acquired by the Corporation by reason of redemption, purchase, conversion or otherwise shall be reissued, and all such shares shall be canceled, retired and eliminated from the shares which the Corporation shall be
authorized to issue.

8. Covenants. So long as any shares of Redeemable Preferred Stock shall be outstanding the provisions of
Section A.8 shall apply to all shares of Redeemable Preferred Stock as if such shares were shares of Convertible Preferred Stock.

C. SERIES B PREFERRED STOCK

1. Designation and Amount. The shares of such series shall be designated as Series B Preferred Stock (the Series B Preferred
Stock); $0.01 par value per share, and the number of shares constituting such series shall be 1,000,000.

2. Dividends and
Distributions.

(A) The dividend rate on the shares of Series B Preferred Stock shall be for each quarterly dividend (hereinafter
referred to as a quarterly dividend period), which quarterly dividend periods shall commence on January 1, April 1, July 1 and October 1 each year (each such date being referred to herein as a
Quarterly Dividend Payment Date) (or in the case of original issuance, from the date of original issuance) and shall end on and include the day next preceding the first date of the next quarterly dividend period, at a rate per quarterly
dividend period (rounded to the nearest cent) equal to the greater of (a) 625.00 or (b) subject to the provisions for adjustment hereinafter set forth, 100 times the aggregate per share amount of all cash dividends, and 100 times the
aggregate share amount (payable in cash, based upon the fair market value at the time the non-cash dividend or other distribution is declared as determined in good faith by the Board of Directors) of all non-cash dividends or other distributions
other than a dividend payable in shares of Common Stock or a subdivision of the outstanding shares of Common Stock (by reclassification or otherwise), declared (but not withdrawn) on the Common Stock, par value $0.001 Par value of Common Stock per
share, of the Corporation (the Common Stock) during the immediately preceding quarterly dividend period, or, with respect to the first quarterly dividend period, since the first issuance of any share or fraction of a share of Series B
Preferred Stock. In the event this Company shall at any time after February 28, 2001 (the Rights Declaration Date) (i) declare any dividend on Common Stock payable in shares of Common Stock, (ii) subdivide the outstanding
Common Stock, or (iii) combine the outstanding Common Stock into a smaller number of shares, then in each such case the amount to which holders of shares of Series B Preferred Stock were entitled immediately prior to such event under clause
(b) of the preceding sentence shall be adjusted by multiplying such amount by a fraction the numerator of which is the number of shares of Common Stock outstanding immediately after such event and the denominator of which is the number of
shares of Common Stock that were outstanding immediately prior to such event.

(B) Dividends shall begin to accrue and be cumulative on
outstanding shares of Series B Preferred Stock from the Quarterly Dividend Payment Date next preceding the date of issue of such shares of Series B Preferred Stock, unless the date of issue of such shares is prior to the record date for the first
Quarterly Dividend Payment Date, in which case dividends on such shares shall begin to accrue from the date of issue of such shares, or unless the date of issue is a Quarterly Dividend Payment Date or is a date after the record date for the
determination of holders of shares of Series B Preferred Stock entitled to receive a quarterly dividend and before such Quarterly Dividend Payment Date, in either of which events such dividends shall begin to accrue and be cumulative from such
Quarterly Dividend Payment Date. Accrued but unpaid dividends shall not bear interest. Dividends paid on the shares of Series B Preferred Stock in an amount less than the total amount of such dividends at the time accrued and payable on such shares
shall be allocated pro rata on a share-by-share basis among all such shares at the time outstanding. The Board of Directors may fix a record date for the determination of holders of shares of Series B Preferred Stock entitled to receive payment of a
dividend or distribution declared thereon, which record date shall be no more than 45 days prior to the date fixed for the payment thereof.

3. Voting Rights. The holders of shares of Series B Preferred Stock shall have the following
voting rights:

(A) Subject to the provision for adjustment hereinafter set forth, each share of Series B Preferred Stock shall entitle the
holder thereof to 100 votes on all matters submitted to a vote of the stockholders of the Corporation. In the event the Corporation shall at any time after the Rights Declaration Date (i) declare any dividend on Common Stock payable in shares
of Common Stock, (ii) subdivide the outstanding Common Stock, or (iii) combine the outstanding Common Stock into a smaller number of shares, then in each such case the number of votes per share to which holders of shares of Series B
Preferred Stock were entitled immediately prior to such event shall be adjusted by multiplying such number by a fraction the numerator of which is the number of shares of Common Stock outstanding immediately after such event and the denominator of
which is the number of shares of Common Stock that were outstanding immediately prior to such event.

(B) Except as otherwise provided
herein, in the Certificate of Incorporation or by law, the holders of shares of Series B Preferred Stock and the holders of shares of Common Stock shall vote together as one class on all matters submitted to a vote of stockholders of the
Corporation.

(C) Except as set forth herein, in the Certificate of Incorporation and in the By-laws, holders of Series B Preferred Stock
shall have no special voting rights and their consent shall not be required (except to the extent they are entitled to vote with holders of Common Stock as set forth herein) for taking any corporate action.

4. Reacquired Shares. Any shares of Series B Preferred Stock purchased or otherwise acquired by the Corporation in any manner whatsoever shall be
retired and canceled promptly after the acquisition thereof. All such shares shall upon their cancellation become authorized but unissued shares of Preferred Stock and may be reissued as part of a new series of Preferred Stock to be created by
resolution or resolutions of the Board of Directors, subject to the conditions and restrictions on issuance set forth herein.

5.
Liquidation, Dissolution or Winding Up. In the event of any voluntary or involuntary liquidation, dissolution or winding up of the Corporation, the holders of the Series B Preferred Stock shall be entitled to receive the greater of
(a) $25,000.00 per share, plus accrued dividends to the date of distribution, whether or not earned or declared, or (b) an amount per share, subject to the provision for adjustment hereinafter set forth, equal to 100 times the aggregate
amount to be distributed per share to holders of Common Stock. In the event the Corporation shall at any time after the Rights Declaration Date (i) declare any dividend on Common Stock payable in shares of Common Stock, (ii) subdivide the
outstanding Common Stock, or (iii) combine the outstanding Common Stock into a smaller number of shares, then in each such case the amount to which holders of shares of Series B Preferred Stock were entitled immediately prior to such event
pursuant to clause (b) of the preceding sentence shall be adjusted by multiplying such amount by a fraction the numerator of which is the number of shares of Common Stock outstanding immediately after such event and the denominator of which is
the number of shares of Common Stock that were outstanding immediately prior to such event.



25



---

6. Consolidation, Merger, Etc, In case the Corporation shall enter into any consolidation, merger,
combination or other transaction in which the shares of Common Stock are exchanged for or changed into other stock or securities, cash and/or any other property, then in any such case the shares of Series B Preferred Stock shall at the same time be
similarly exchanged or changed in an amount per share (subject to the provision for adjustment hereinafter set forth) equal to 100 times the aggregate amount of stock, securities, cash and/or any other property (payable in kind), as the case may be,
into which or for which each share of Common Stock is changed or exchanged. In the event the Corporation shall at any time after the Rights Declaration Date (i) declare any dividend on Common Stock payable in shares of Common Stock,
(ii) subdivide the outstanding Common Stock, or (iii) combine the outstanding Common Stock into a smaller number of shares, then in each such case the amount set forth in the preceding sentence with respect to the exchange or change of
shares of Series B Preferred Stock shall be adjusted by multiplying such amount by a fraction the numerator of which is the number of shares of Common Stock outstanding immediately after such event and the denominator of which is the number of
shares of Common Stock that were outstanding immediately prior to such event.

7. No Redemption. The shares of Series B Preferred
Stock shall not be redeemable.

8. Fractional Shares. Series B Preferred Stock may be issued in fractions of a share which shall
entitle the holder, in proportion to such holders fractional shares, to exercise voting rights, receive dividends, participate in distributions and have the benefit of all other rights of holders of Series B Preferred Stock. All payments made
with respect to fractional shares hereunder shall be rounded to the nearest whole cent.

9. Certain Restrictions.

(A) Whenever quarterly dividends or other dividends or distributions payable on the Series B Preferred Stock as provided in Section 2 are in
arrears, thereafter and until all accrued and unpaid dividends and distributions, whether or not declared, on shares of Series B Preferred Stock outstanding shall have been paid in full, the Corporation shall not:

(i) declare or pay dividends on, make any other distributions on, or redeem or purchase or otherwise acquire for consideration any shares
of stock ranking junior (either as to dividends or upon liquidation, dissolution or winding up) to the Series B Preferred Stock;

(ii) declare or pay dividends on or make any other distributions on any shares of stock ranking on a parity (either as to dividends or upon liquidation, dissolution or winding up) with the Series B Preferred Stock, except dividends paid
ratably on the Series B Preferred Stock and all such parity stock on which dividends are payable or in arrears in proportion to the total amounts to which the holders of all such shares are then entitled;



26



---

(iii) redeem or purchase or otherwise acquire for consideration shares of any stock
ranking on a parity (either as to dividends or upon liquidation, dissolution or winding up) with the Series B Preferred Stock, provided that the Corporation may at any time redeem, purchase or otherwise acquire shares of any such parity stock in
exchange for shares of any stock of the Corporation ranking junior (either as to dividends or upon dissolution, liquidation or winding up) to the Series B Preferred Stock; or

(iv) purchase or otherwise acquire for consideration any shares of Series B Preferred Stock, or any shares of stock ranking on a parity
with the Series B Preferred Stock, except in accordance with a purchase offer made in writing or by publication (as determined by the Board of Directors) to all holders of such shares upon such terms as the Board of Directors, after consideration of
the respective annual dividend rates and other relative rights and preferences of the respective series and classes shall determine in good faith will result in fair and equitable treatment among the respective series or classes.

(B) The Corporation shall not permit any subsidiary of the Corporation to purchase or otherwise acquire for consideration any shares of stock of the
Corporation unless the Corporation could, under paragraph (A) of this Section 9, purchase or otherwise acquire such shares at such time and in such manner.

10. Ranking. The Series B Preferred Stock shall be junior to all other Series of the Corporations preferred stock as to the payment of dividends and the distribution of assets, unless the terms of any
series shall provide otherwise.

11. Amendment. The Certificate of Incorporation of the Corporation shall not be amended in any
manner which would materially alter or change the powers, preferences or special rights of the Series B Preferred Stock so as to affect them adversely without the affirmative vote of the holders of two-thirds or more of the outstanding shares of
Series B Preferred Stock voting together as a single class.

D. COMMON STOCK

1. Designation; Ranking. A total of 200,000,000 shares of the Corporations common stock shall be designated as Common Stock, $.01 par value
per share (the Common Stock).

2. Voting.

(a) Election of Directors. The holders of Common Stock voting together with the holders of outstanding Convertible Preferred Stock
as a single class, shall be entitled to elect all of the Directors of the Corporation, other than the Directors who are subject to election by the holders of Convertible Preferred Stock or Redeemable Preferred Stock as a separate class for so long
as any shares of Convertible Preferred Stock or Redeemable Preferred Stock remain outstanding, and thereafter shall be entitled to elect all of the Directors of the Corporation. Such Directors shall be the candidates receiving the highest number of
affirmative votes entitled to be cast (with each holder entitled to cast one vote for or against each candidate with respect to each share held by such holder), with votes cast against such candidates and votes withheld having no legal effect. The
election of



27



---

such Directors shall occur at the annual meeting of holders of capital stock or at any special meeting called and held in accordance with the by-laws of the
Corporation. Subject to the rights of the holders of any series of Preferred Stock then outstanding, newly created directorships resulting from any increase in the authorized number of Directors or any vacancies in the Board of Directors resulting
from death, resignation or other cause (other than the removal from office by a vote of the stockholders) may be filled only by a majority vote of the Directors then in office, though less than a quorum. Directors so chosen shall hold office for a
term expiring at the next annual meeting of the stockholders at which the term of office to which they have been elected expires and until their respective successors are elected, except that in the case of death or resignation of any Director, in
which case the Director so chosen shall hold office for a term expiring at the next annual meeting of stockholders. No decrease in the number of directors constituting the Board of Directors shall shorten the term of any incumbent Director.

(b) Other Voting. The holder of each share of Common Stock shall be entitled to one vote for each such share as
determined on the record date for the vote or consent of stockholders and shall vote together with the holders of the Convertible Preferred Stock as a single class upon any items submitted to a vote of stockholders, except as otherwise provided
herein.

3. Dividends. Subject to the payment in full of all preferential dividends to which the holders of the Convertible
Preferred Stock and the Redeemable Preferred Stock are entitled hereunder, the holders of Common Stock shall be entitled to receive dividends out of funds legally available therefor at such times and in such amounts as the Board of Directors may
determine in its sole discretion. The Board of Directors shall give the holders of Convertible Preferred Stock twenty (20) days prior written notice of the declaration of any such dividends, and the record date for such dividends shall not
precede the expiration of such twenty (20) day period.

4. Liquidation. Upon any Liquidation Event, after the payment or
provision for payment of all debts and liabilities of the Corporation and all preferential amounts to which the holders of Convertible Preferred Stock or Redeemable Preferred Stock, as applicable, are entitled with respect to the distribution of
assets in liquidation, the holders of Common Stock (and, to the extent applicable under Section A.4(a), Convertible Preferred Stock) shall be entitled to share ratably in the remaining assets of the Corporation available for distribution.

5. Fractional Shares; Uncertificated Shares. The Corporation may issue fractional shares (up to five decimal places) of Common
Stock. Fractional shares shall be entitled to dividends (on a pro rata basis), and the holders of fractional shares shall be entitled to all rights as stockholders of the Corporation to the extent provided herein and under applicable law in respect
of such fractional shares. Shares of Common Stock, or fractions thereof, may, but need not be represented by share certificates. Such shares, or fractions thereof, not represented by share certificates (the Uncertificated Common Shares)
shall be registered in the stock records book of the Corporation. The Corporation at any time at its sole option may deliver to any registered holder of such shares share certificates to represent Uncertificated Common Shares previously issued (or
deemed issued) to such holder.

ARTICLE V

In furtherance of and not in limitation of powers conferred by statute, it is further provided:

1. Board of Directors.

(a) Election of Directors need not be by written ballot unless the by-laws of the Corporation so provide.

(b)
Subject to Section A.8(g) hereof, the number of directors shall be fixed from time to time exclusively by the Board of Directors pursuant to a resolution adopted by a majority of the total number of authorized directors (whether or not there exist
any vacancies in previously authorized directorships at the time any such resolution is presented to the Board for adoption). Following the Corporations first QPO, the directors shall be divided into three classes with the term of office of
the first class to expire at the annual meeting of the stockholders held in 2000; the term of office of the second class to expire at the meeting of the stockholders held in 2001; the term of office of the third class to expire at the annual meeting
of the stockholders in 2002; and thereafter for each such term to expire at each third succeeding annual meeting of stockholders after such election. Subject to the rights of the holders of any series of Preferred Stock then outstanding, a vacancy
resulting from the removal of a director by the stockholders as provided in Article V, Section 3 below may be filled at a special meeting of the stockholders held for that purpose.

2. Except as set forth in Section A.8(c), the Board of Directors is expressly authorized to adopt, amend, or repeal the by-laws of the Corporation to the
extent specified therein. Following the Corporations first QPO, the by-laws of the Corporation may be amended or repealed, and new by-laws may be adopted, by the affirmative vote of the holders of at least 66-2/3% of the voting power of all
the then outstanding shares of the capital stock of the Corporation entitled to vote generally in the election of directors, voting together as a single class, or by a vote of at least 66-2/3% of the number of directors of the Corporation then
authorized, in the manner prescribed by the laws of the State of Delaware.

3. Following the Corporations first QPO any director or
the entire Board of Directors may be removed from office before the expiration of the applicable term of office only with cause.

ARTICLE
VI

Meetings of stockholders may be held within or without the State of Delaware, as the by-laws may provide. Any action taken by the
written consent of the stockholders of the Corporation must include the consent of the holder or holders of not less than a majority in voting power of the outstanding shares of Convertible Preferred Stock (or Redeemable Preferred Stock, as
applicable). Following the closing of the Corporations first QPO, the stockholders may no longer take action by written consent and may act only at an annual or special meeting.

ARTICLE VII

To the extent permitted by law, the books of the Corporation may be kept outside the State of Delaware at such place or places as may be designated in the by-laws of the Corporation or from time to time by its Board
of Directors.

ARTICLE VIII

No person shall be personally liable to the Corporation or its stockholders for monetary damages for breach of his or her fiduciary duty as a Director of the Corporation, except for liability (a) for any breach of the Directors
duty of loyalty to the Corporation or its stockholders, (b) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (c) under Section 174 of the General Corporation Law of the
State of Delaware, or (d) for any transaction from which the Director derived an improper personal benefit. If the General Corporation Law of the State of Delaware is amended after the effective date of this Restated Certificate of
Incorporation to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of each past or present Director of the Corporation shall be eliminated or limited to the fullest extent permitted by
the General Corporation Law of the State of Delaware, as so amended.

Any repeal or modification of this Article VIII by (a) the
stockholders of the Corporation or (b) an amendment to the General Corporation Law of the State of Delaware (unless such statutory amendment specifically provides to the contrary) shall not adversely affect any right or protection existing at
the time of such repeal or modification with respect to any acts or omissions occurring either before or after such repeal or modification, of a person serving as a Director prior to or at the time of such repeal or modification.

ARTICLE IX

The Corporation reserves
the right to amend, alter, change or repeal any provision contained in this Certificate of Incorporation, in the manner now or hereafter prescribed by statute, provided, however, that following the Corporations first QPO the
affirmative vote of at least 66-2/3% of the voting power of all the then outstanding shares of the capital stock of the Corporation entitled to vote generally in the election of directors, voting together as a single class, shall be required to
amend or repeal Article V, Article VI, Article VIII, or this Article IX. All rights conferred upon stockholders herein are granted subject to this reservation.

IN WITNESS WHEREOF, this Restated Certificate of Incorporation has been executed by the undersigned duly authorized officer of the Corporation on this 13th day of September, 2006.
