other series or classes of capital stock of the Corporation, and shall be payable either in cash or, at the Corporation’s option, by issuance of additional fully paid and nonassessable shares of Series A Preferred Stock in lieu of the payment

 -2-

 
portion of the dividend otherwise payable on any dividend payment date, cumulative annual dividends (the “Accruing Dividends”) on the Series A Preferred Stock at a rate of
5% per annum on $1,000 per share (which value per share shall be proportionately adjusted to reflect any stock dividend, stock split, combination of shares, reclassification, reorganization, recapitalization or other similar event affecting the
Series A Preferred Stock), compounded quarterly from and after the date of issuance of such shares of Series A Preferred Stock. To the extent that dividends are declared on any Junior Stock, (a) no such dividends shall be paid until all accrued

(b) and (c), collectively, the “Liquidation Preference Events”), distributions to the stockholders of the Corporation shall be made in the following manner. The holders of the Series A Preferred Stock shall be entitled to receive, in
cash, prior and in preference to any other distribution of any of the assets of the Corporation to the holders of all series and classes of the Corporation’s stock by reason of their ownership of such stock, an amount per share equal to the sum
of (A) $1,000 (as adjusted to reflect any stock dividend, stock split, combination of shares, reclassification, reorganization, recapitalization or other similar event affecting the Series A Preferred Stock) plus (B) an amount equal
to the amount of the aggregate Accruing Dividends then accrued on such share of Series A Preferred Stock and not previously paid (such sum being referred to as the “Series A Preferential Amount”). 

If cash assets of the Corporation shall be insufficient to permit the payment of the full Series A Preferential Amount to the holders of
Series A Preferred Stock, then all cash assets legally available for distribution shall be distributed ratably among the holders of Series A Preferred Stock in accordance with the aggregate liquidation preferences of the shares of the Series A
Preferred Stock held by each of them, and the remaining assets of the Corporation shall be distributed to them to the extent of any Series A Preferential Amount payable, based on the fair value of such assets, and if such remaining assets of the
Corporation shall be insufficient to permit the payment of the full Series A Preferential Amount, then the entire assets of the Corporation legally available for distribution shall be distributed ratably among the holders of Series A Preferred Stock
in accordance with the aggregate liquidation preferences of the shares of Series A Preferred Stock held by each of them. After payment has been made to the holders of Series A Preferred Stock of the full amount to which they are entitled, the
holders of Junior Stock shall be entitled to share in the remaining assets without participation by the holders of Series A Preferred Stock. 

5. VOTING RIGHTS. Except as required by Delaware law or as otherwise provided by the Certificate of Incorporation (including this Certificate),
the holders of Series A Preferred Stock shall have no right to vote their shares at any stockholders’ meeting or provide consent to any action taken by stockholders in writing in lieu of a meeting, nor shall they be entitled to notice of any
stockholders’ meeting or solicitation of stockholders’ consents.

 6. REDEMPTION. 

6.1. Redemption at the Holder’s Option. The holders of Series A Preferred Stock do not have a mandatory
redemption right. 
 6.2. Redemption at the Corporation’s Option. The Corporation may at any time
redeem, in cash, to the extent of lawfully available funds therefor, at a price per share equal to the Series A Preferential Amount allocable to each share of Series A Preferred Stock, an aggregate number of shares of Series A Preferred Stock
specified in the notice delivered pursuant to Section 6.3. 
 6.3. Notice of Redemption. Written
notice of redemption of Series A Preferred Stock pursuant to Section 6.2 shall be given not fewer than one day prior to the redemption date, to each holder of record of shares of the Series A Preferred Stock, at such holder’s address on
the books of the Corporation. Each such notice shall state: (a) the redemption date; (b) the number of shares of the Series A Preferred Stock to be redeemed; (c) the Series A Preferential Amount allocable to the shares of such
holder to be redeemed; and (d) the place or places where certificates representing such shares are to be surrendered for payment of the Series A Preferential Amount allocable to such holder’s shares to be redeemed. If fewer than all of the
shares of Series A Preferred Stock are to be redeemed on any redemption date, Series A Preferred Stock shall be redeemed from the holders thereof pro rata from each holder based on the number of shares of Series A Preferred Stock then
held by each holder. 
 6.4. Cancellation of Shares. If any shares of Series A Preferred Stock are
redeemed pursuant to this Section 6 and the holder thereof fails to deliver the certificate representing such shares in accordance with this Certificate, the Corporation may, at its option, in addition to all other remedies it may have, cancel
on its books such certificate representing such shares to be redeemed. 
 7. CERTAIN COVENANTS. 

7.1. Special Restrictions. At any time when shares of Series A Preferred Stock are outstanding, except where the
vote or written consent of the holders of a greater number of shares of the Corporation is required by law or by the Certificate of Incorporation, and in addition to any other vote required by law or by the Certificate of Incorporation, without the
affirmative vote of the Required Holders, given at a meeting or by written consent in lieu of a meeting, consenting or voting (as the case may be) separately as a class, the Corporation will not: 

7.1.1. create or authorize the creation of any additional class or series of shares of stock, or issue any shares thereof,
unless the same ranks junior to the Series A Preferred Stock as to the distribution of assets upon the occurrence of any Liquidation Preference Event (any such class or series of shares of stock, including without limitation any currently or
subsequently issued 

  
 -4-

 
or issuable Common Stock, “Junior Stock”), or increase the authorized amount of shares of the Series A Preferred Stock or increase the authorized amount of shares of any
additional class or series of capital stock of the Corporation unless the same ranks junior to the Series A Preferred Stock as to the distribution of assets upon the occurrence of any Liquidation Preference Event, or create or authorize any
instrument or security convertible into shares of Series A Preferred Stock or into shares of any other class or series of stock unless the same ranks junior to the Series A Preferred Stock as to the distribution of assets upon the occurrence of any
Liquidation Preference Event, whether any such creation, authorization or increase shall be by means of amendment to the Certificate of Incorporation or by merger, consolidation or otherwise; 

7.1.2. amend, alter or repeal its Certificate of Incorporation, bylaws or similar organizational documents, whether by
amendment, merger, consolidation or otherwise, in a manner that is adverse to the holders of Series A Preferred Stock in any respect; 
 7.1.3. purchase or set aside any sums for the purchase or redemption of any shares of stock or other securities other than the Series A Preferred Stock, except for repurchases required or otherwise
permitted under the Management Stockholders’ Agreement, by and among the Corporation and the parties thereto, dated as of October 26, 2007, as amended, or any other agreement between the Corporation and an employee of the Corporation or
its direct or indirect subsidiaries; 
 7.1.4. consolidate or merge into or with any other entity or entities or
sell or transfer all or substantially all its assets or the assets of the Corporation, except that the Corporation may, without the vote or consent of the Required Holders, effectuate a merger in which (i) the Corporation is the surviving
corporation and (ii) the stockholders of the Corporation immediately prior to the merger hold more than 50% of the outstanding voting power of the surviving corporation (assuming conversion of all convertible securities and exercise of all
outstanding options and warrants); or 
 7.1.5. declare, pay or make any dividends or other distributions on any
Junior Stock. 
 7.2. No Impairment. The Corporation will not, by amendment of its Certificate of
Incorporation or through any reorganization, recapitalization, transfer of all or a substantial portion of its assets, consolidation, merger, dissolution, issue or sale of securities, closing of transfer books or any other voluntary action, avoid or

  
 -5-

 
seek to avoid the observance or performance of any of the terms to be observed or performed under this Certificate by the Corporation, but will at all times in good faith assist in carrying out
all the provisions of this Certificate and in taking all such action as may be necessary or appropriate in order to protect the rights of the holders of Series A Preferred Stock against impairment as hereinabove contemplated. 

7.3. Notice of Certain Events. If at any time: 

(a) the Corporation shall declare any dividend or distribution payable to the holders of any of its Junior Stock;

 (b) any recapitalization or reorganization of the Corporation, or consolidation or merger of the Corporation
with, or sale of all or substantially all of its assets to, another corporation or business organization shall occur; or 
 (c) a voluntary or involuntary dissolution, liquidation or winding up of the Corporation shall occur; 
 then, in any one or more of such cases, the Corporation shall give the registered holders of the Series A Preferred Stock written notice of the date on which a record shall be taken for such dividend,
distribution or subscription rights or for determining stockholders entitled to vote upon such recapitalization, consolidation, merger, sale, dissolution, liquidation or winding up and of the date when any such transaction shall take place, as the
case may be. Such notice shall also specify the date as of which the holders of Junior Stock of record shall participate in such dividend, distribution or subscription rights, or shall be entitled to exchange their Junior Stock for securities or
other property deliverable upon such recapitalization, consolidation, merger, sale, dissolution, liquidation or winding up, as the case may be. Such written notice shall be given at least five days prior to the record date with respect thereto.

 7.4. No Reissuance of Series A Preferred Stock. No shares of Series A Preferred Stock acquired by the
Corporation by reason of redemption, purchase 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. The Corporation may from time to time
take such appropriate corporate action as may be necessary to reduce the authorized number of shares of Series A Preferred Stock accordingly. 

8. RESTRICTIONS ON TRANSFER. Until the earlier of (i) October 26, 2012 and (ii) a Qualified Public Offering (the “Initial
Holding Period”), no holder may transfer any Series A Preferred Stock except (i) to a Permitted Transferee or (ii) with the prior written consent of the Manager, which consent may be withheld by the Manager in its sole discretion.

 9. AMENDMENTS. The provisions of these terms of the Series A Preferred Stock may not be amended, modified or waived (whether through
amendment to the Certificate of Incorporation, merger, consolidation or otherwise) without the written consent or affirmative vote of the Required Holders, acting as a separate class. Except to the extent required by law, the vote of the holders of
any other class of capital stock of the Corporation is not 

  
 -6-

 
required for the amendment, modification or waiver (whether through merger, consolidation or otherwise) of the terms of the Series A Preferred Stock as set forth in this Certificate of
Designation.

 Exhibit 4.10 
 FORM OF WARRANT 
 NEITHER THIS WARRANT NOR THE SHARES OF COMMON STOCK ISSUABLE UPON ITS
EXERCISE HAS BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR ANY APPLICABLE STATE SECURITIES LAWS, AND MAY NOT BE OFFERED, SOLD OR TRANSFERRED OR OTHERWISE DISPOSED OF UNLESS (I) PURSUANT TO
REGISTRATION UNDER THE ACT OR (II) IN COMPLIANCE WITH AN EXEMPTION THEREFROM AND ACCOMPANIED, IF REQUESTED BY THE COMPANY, WITH AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE COMPANY TO THE EFFECT THAT SUCH TRANSFER IS BEING MADE IN COMPLIANCE
WITH AN EXEMPTION THEREFROM (UNLESS SUCH TRANSFER IS TO AN AFFILIATE OF THE HOLDER). 
 THE VOTING OF THE SHARES ISSUABLE UPON EXERCISE OF THIS
WARRANT, AND THE SALE, ENCUMBRANCE OR OTHER DISPOSITION OF THIS WARRANT OR SUCH SHARES ARE SUBJECT TO THE PROVISIONS OF A STOCKHOLDERS AGREEMENT (AS AMENDED AND RESTATED AND IN EFFECT FROM TIME TO TIME), A COPY OF WHICH MAY BE INSPECTED AT THE
PRINCIPAL OFFICE OF THE COMPANY OR OBTAINED FROM THE COMPANY WITHOUT CHARGE. 
 SIERRA HOLDINGS CORP. 

WARRANT TO PURCHASE COMMON STOCK 
 FOR VALUE RECEIVED, Sierra Holdings Corp., a Delaware corporation (the “Company”), hereby grants to
                     (“Holder”) the right to purchase
            shares (“Shares”) of Common Stock, par value $0.001 per share (the “Common Stock”). The exercise price per Share (the
“Initial Purchase Price”) of the warrants granted hereby shall initially equal $3.25. The Initial Purchase Price and the number of Shares purchasable hereunder are subject to adjustment as provided in Section 2 of this Warrant.
This Warrant may be exercised at any time and from time to time prior to the tenth (10th) anniversary of the date hereof (the “Expiration Date”). This Warrant shall expire and be of no further force or effect at the earlier of
the time when it has been exercised or 5:00 p.m., New York time, on the Expiration Date. 
 1. Exercise of Warrant. This Warrant
may be exercised in whole or in part, at any time and from time to time by the Holder prior to the Expiration Date by surrendering this Warrant, together with a Notice of Exercise in the form appearing at the end hereof properly completed and duly
executed by the Holder or on behalf of the Holder by the Holder’s duly authorized representative, to the Company at its principal executive office (or at the office of the agency maintained for such purpose). 

If the Holder has elected a “cash payment” exercise, the Notice of Exercise shall be accompanied by payment in cash or by check payable to the
order of the Company in an amount equal to the Purchase Price (as defined in Section 2) multiplied by the number of Shares being purchased pursuant to such exercise. If the Holder has elected a “cashless exercise”, the number of
Shares obtainable upon exercise of this Warrant shall be reduced to a number of Shares equal to (a) the number of Shares with respect to which this Warrant is then being exercised multiplied by (b) a

 
fraction, the numerator of which is the excess of the Fair Market Value (as defined below) of one Share over the Purchase Price, and the denominator of which is the Fair Market Value of
one Share. “Fair Market Value” means (i) the latest available closing price per Share on the principal trading market for the Shares, if the Shares are traded in the public markets, or (ii) the fair market value as
reasonably and in good faith determined by the Company, if the Shares are not then traded in the public markets. 
 In the event of an exercise
of this Warrant, certificates for the Shares purchased pursuant to such exercise shall be delivered to the Holder within ten (10) days of receipt of such notice and, unless this Warrant has been fully exercised or has expired, a new Warrant
representing the portion of the Shares, if any, with respect to which this Warrant shall not then have been exercised shall also be issued to the Holder within such ten day period. Upon receipt by the Company of this Warrant and such Notice of
Exercise, together with the applicable aggregate Purchase Price, the Holder shall be deemed to be the holder of record of the Shares purchased pursuant to such exercise, notwithstanding that Certificates representing such Shares shall not then be
actually delivered to the Holder or that such Shares are not then set forth on the stock transfer book of the Company. 
 2. Adjustment of
Exercise Consideration and Purchase Price. The Exercise Consideration (as defined below) which the Holder of this Warrant shall be entitled to receive upon the exercise hereof shall be determined by multiplying the Exercise Consideration
which would otherwise, but for the provisions of this Section 2, be issuable upon such exercise, by the fraction of which (a) the numerator is the Initial Purchase Price and (b) the denominator is the Purchase Price in effect on the
date of such exercise. The “Purchase Price” shall initially be the Initial Purchase Price, shall be adjusted and readjusted from time to time as provided in this Section 2 and, as so adjusted or readjusted, shall remain in
effect until a further adjustment or readjustment thereof is required by this Section 2. 
 (a) Adjustments for Subdivisions, Stock
Dividends, Combinations or Consolidation. In the event the outstanding shares of Common Stock (or any successor equity securities that are a part of the Exercise Consideration) shall be increased by way of stock (or successor equity securities)
issued as a dividend or other distribution for no consideration or subdivided by stock split or otherwise into a greater number of shares of Common Stock (or successor equity securities), the Purchase Price then in effect shall, concurrently with
the effectiveness of such increase or subdivision, be proportionately decreased. In the event the outstanding shares of Common Stock (or any successor equity securities that are a part of the Exercise Consideration) shall be combined or
consolidated, by reclassification or otherwise, into a lesser number of shares of Common Stock (or successor equity securities), the Purchase Price then in effect shall, concurrently with the effectiveness of such combination or consolidation, be
proportionately increased. 
 (b) Subsequent Events. In the event of any reorganization, recapitalization, merger or consolidation of the
Company or its successor, or in the event of any reclassification, exchange, substitution or other event in which the Common Stock issuable upon exercise of this Warrant is changed into the same or a different number of shares of any class or
classes of stock, the Warrant shall be exercisable for such shares or other interests as the Holder would have been entitled if the Warrant had been exercised for Common Stock immediately prior to such event (the consideration into which the Warrant
is exercisable (including, prior to or in the absence of 

  
 -2-

 
any event described in this Section 2(b), the Shares), the “Exercise Consideration”), and the terms of this Warrant shall be deemed to be restated as necessary to give
effect to such change in the Exercise Consideration. In such an event, the term “Shares” for the purposes of this Warrant shall mean the number of shares of capital stock of the Company into which the Common Stock has been
reclassified or otherwise changed. In the event that an offer is made to purchase all of the outstanding shares or all or substantially all of the assets of the Company, or the Company proposes to amalgamate or merge with another company, the
Company shall have the right, subject to the right of the Holder to exercise such Warrant, to require that as a condition of closing of any such transaction, the participant shall accept in full substitution for this Warrant, an equivalent Warrant
of the successor or purchasing company, in which case this Warrant shall be canceled upon the issuance of such substituted Warrant to the Holder. Without limiting the obligations of the Holder under the Stockholders Agreement, the Company shall not
effect any reorganization, recapitalization, merger or consolidation unless, prior to the consummation thereof, the successor entity (if other than the Company) resulting from the consolidation or merger or the entity purchasing such assets assumes
by written instrument (in form and substance satisfactory to the Holders of a majority of the Warrants then remaining outstanding and unexpired) the obligation to deliver to each Holder such shares of stock, securities or assets as, in accordance
with the foregoing provisions, such holder may be entitled to acquire; provided, that any assumption shall not relieve the Company of its obligations hereunder. 
 (c) Adjustments for Other Dividends and Distributions. In the event the Company at any time or from time to time after the date on which this Warrant was first issued while this Warrant remains
outstanding and unexpired in whole or in part 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 Company (other than shares of
Common Stock), then and in each such event provision shall be made so that the Holder shall receive upon exercise hereof, in addition to the number of shares of Common Stock issuable hereunder, the kind and amount of securities of the Company which
the Holder would have been entitled to receive had this Warrant been exercised into Common Stock on the date of such event and had the Holder thereafter, during the period from the date of such event to and including the exercise date, retained any
such securities receivable, giving application to all adjustments called for during such period under this Section 2 with respect to the rights of the Holder. 
 3. Covenants. 
 (a) No Impairment. The Company will not, by amendment of its
charter as in effect on the date hereof or through any reorganization, recapitalization, transfer of all or a substantial portion of its 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 under this Warrant by the Company, but will at all times in good faith assist in carrying out all the provisions of this Warrant and in taking all such
action as may be necessary or appropriate in order to protect the rights of the Holder of the Warrant against impairment. Without limiting the generality of the foregoing, the Company will (a) not increase the par value of any shares of Common
Stock obtainable upon the exercise of this Warrant and (b) take all such actions as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable shares of Common Stock upon the exercise of
this Warrant. 

  
 -3-

 (b) Reservation of Shares. So long as the Warrant shall remain outstanding, the Company shall at all
times reserve and keep available, free from preemptive rights, out of its authorized capital stock, for the purpose of issuance upon exercise of the Warrant, the full number of shares of Common Stock then issuable upon exercise of the Warrant. If
the Common Stock shall be listed on any national stock exchange, the Company at its expense shall include in its listing application all of the shares of Common Stock issuable upon exercise of the Warrant at any time, including as a result of
adjustments in the outstanding Common Stock or otherwise. 
 (c) Validity of Shares. All shares of Common Stock issuable upon exercise of
this Warrant will be duly and validly issued, fully paid and nonassessable and will be free of restrictions on transfer, other than restrictions on transfer under the Stockholders Agreement or any agreement between the Holder and the Company and
under applicable state and federal securities laws, and will be free from all taxes, liens and charges in respect of the issue thereof (other than taxes in respect of any transfer occurring contemporaneously or otherwise specified herein). The
Company shall take all such actions as may be necessary to ensure that all such shares of Common Stock may be so issued without violation of any applicable law or governmental regulation or any requirements of any domestic stock exchange upon which
shares of Common Stock may be listed (except for official notice of issuance which shall be immediately delivered by the Company upon each such issuance). 
 (d) Notice of Certain Events. If at any time, (1) the Company shall declare any dividend or distribution payable to the holders of its Common Stock, (2) the Company shall offer for
subscription pro rata to the holders of Common Stock any additional shares of capital stock of any class or any other rights, (3) there shall be any recapitalization of the Company or consolidation or merger of the Company with, or sale of all
or substantially all of its assets to, another corporation or business organization, or, if sooner, promptly following any agreement to do any of the foregoing, or (4) there shall be a voluntary or involuntary dissolution, liquidation or
winding up of the Company, then, in any one or more of such cases, the Company shall give the registered Holder of this Warrant ten days’ prior written notice (or such other time period set forth in the Company’s Amended and Restated
Certificate of Incorporation), in a manner permitted under the Company’s Amended and Restated Stockholders’ Agreement (as amended from time to time, the “Stockholders Agreement”), dated as of December 18, 2009, by and
among the Stockholders (as defined therein) party thereto and the Company), of the date on which a record shall be taken for such dividend, distribution or subscription rights or for determining stockholders entitled to vote upon such
recapitalization, consolidation, merger, sale, dissolution, liquidation or winding up and of the date when any such transaction shall take place, as the case may be. Such notice shall also specify the date as of which the holders of Common Stock of
record shall participate in such dividend, distribution or subscription rights, or shall be entitled to exchange their Common Stock for securities or other property deliverable upon such recapitalization, consolidation, merger, sale, dissolution,
liquidation or winding up, as the case may be. The Company shall also give such notices to the registered Holder of this Warrant to the extent and in the manner provided in the Company’s Stockholders Agreement. 

4. Legend. Each certificate for Shares issued upon the exercise of the Warrant, each certificate issued upon the direct or indirect
transfer of any Shares and each Warrant issued upon direct or indirect transfer or in substitution for any Warrant shall be stamped or otherwise imprinted with legends in substantially the form set forth on the face of this Warrant. 

  
 -4-

 5. Ownership of Warrants. The Company may treat the person in whose name any Warrant is
registered on the register kept at the principal executive office of the Company (or at the office of the agency maintained for such purpose) as the owner and holder thereof for all purposes, notwithstanding any notice to the contrary. Subject to
the preceding sentence, a Warrant, if properly assigned, may be exercised by a new Holder without a new Warrant first having been issued. 
 6.
Replacement of Warrants. Upon receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of any Warrant and, in the case of any such mutilation, upon surrender of such Warrant for
cancellation at the principal executive office of the Company (or at the office of the agency maintained for such purpose), the Company at its expense will execute and deliver, in lieu thereof, a new Warrant of like tenor and dated the date hereof.

 7. Remedies. In the event of a breach by the Company of any of its obligations under this Warrant, the Holder, in addition to
being entitled to exercise all rights granted by law, including recovery of damages, will be entitled to specific performance of its rights under this Warrant. The Company agrees that monetary damages would not provide adequate compensation for any
losses incurred by reason of its breach of any of the provisions of this Warrant. 
 8. No Liabilities or Rights as a
Stockholder. Nothing contained in this Warrant shall be construed as imposing any liabilities on the Holder as a stockholder of the Company, whether such liabilities are asserted by the Company or by creditors of the Company. Until
the exercise of this Warrant, the Holder shall not have nor exercise any rights by virtue hereof as a stockholder of the Company. Notwithstanding the foregoing, in the event (a) the Company effects a split of the Common Stock by means of a
stock dividend and the Exercise Price of and the number of Shares are adjusted as of the date of the distribution of the dividend (rather than as of the record date for such dividend), and (b) the Holder exercises this Warrant between the
record date and the distribution date for such stock dividend, the Holder shall be entitled to receive, on the distribution date, the stock dividend with respect to the shares of Common Stock acquired upon such exercise, notwithstanding the fact
that such shares were not outstanding as of the close of business on the record date for such stock dividend. 
 9. Notices. Any
notice or other communication in connection with this Warrant shall be deemed to be delivered if given in accordance with the provisions of Section 5.10 of the Company’s Stockholders Agreement. 

10. Permits and Taxes. The Company shall, at its own expense, apply for and obtain any and all permits, approvals, authorizations, licenses
and orders that may be necessary for the Company lawfully to issue the Shares on exercise of this Warrant. On exercise of this Warrant, the Company shall pay any and all issuance taxes that may be payable in respect of any issuance or delivery of
the Shares. The Company shall not, however, be required to pay, and Holder shall pay, any tax that may be payable in respect of any transfer involved in the issuance and delivery of the Shares in a name other than that of Holder, and no such
issuance and delivery shall be made unless and until the person requesting such issuance shall have paid to the Company the amount of any such tax or shall have established to the Company’s reasonable satisfaction that such tax has been paid.

  
 -5-
