connection therewith); (ii) if a registration undertaken pursuant to this Section 3 shall involve an Underwritten Offering, any holder of Registrable Securities requesting to be included in such registration may elect, in writing at least
20 days prior to the effective date of the registration statement filed in connection with such registration, not to register the offer and sale of such holder’s Registrable Securities in connection with such registration; and (iii) if, at
any time after the 180-day or shorter period specified in Section 4(b), the sale of the securities has not been completed, the Company may withdraw from the registration on a pro rata basis (based on the number of Registrable Securities

managing underwriter or underwriters advise the Company in writing that, in its or their opinion, the total number of shares of Common Stock to be included in such registration, including the Registrable Securities requested to be included pursuant
to this Section 3, exceeds the maximum number of shares of Common Stock specified by the managing underwriter or underwriters that may be distributed without materially and adversely affecting the price, timing or distribution of such shares of
Common Stock, then the Company shall include in such registration only such maximum number of Registrable Securities which, in the reasonable opinion of such underwriter or underwriters, can be sold in the following order of priority:
(i) first, all of the shares of Common Stock that the Company proposes to sell for its own account, if any, (ii) second, the Registrable Securities of ValueAct Capital and any ValueAct Capital Affiliates (as defined in the Securities
Holders Agreement) and the Registrable Securities of the Management Investors and their Permitted Transferees that are requested to be included in such Incidental Registration, and (iii) third, the Registrable Securities of any other holder of
Registrable Securities that are requested to be included in such Incidental Registration. To the extent that shares of Common Stock to be included in the Incidental Registration must be allocated among the holder(s) of Registrable Securities
pursuant to clauses (ii) and (iii) above, such shares shall be allocated pro rata among the applicable holder(s) of Registrable Securities based on the number of shares of Common Stock that such holder(s) of Registrable Securities shall
have requested to be included therein.

with any registration of Registrable Securities requested pursuant to this Section 3. 
 (d) Liability for Delay.

 (e) Participation in Underwritten Registrations. No holder of Registrable
Securities may participate in any Underwritten Registration hereunder unless such holder (i) agrees to sell his, her or its Common Stock on the basis provided in any underwriting arrangements approved by the persons who have selected the
underwriter and (ii) accurately completes in a timely manner and executes all questionnaires, powers of attorney, escrow agreements, underwriting agreements and other documents customarily required under the terms of such underwriting
arrangements. 
 4. Registration Procedures. If and whenever the Company is required to use its best efforts to effect or cause the
registration of any Registrable Securities under the Securities Act as provided in this Agreement, the Company will, as expeditiously as reasonably possible: 
 (a) prepare and file with the Commission a registration statement with respect to such Registrable Securities, and use its best efforts to
cause such registration statement to become effective and to keep the sellers of Registrable Securities advised in writing of the initiation and progress of proceedings regarding such registration, provided, however, that the Company
may discontinue any registration of its securities which is being effected pursuant to Section 3 herein at any time prior to the effective date of the registration statement relating thereto (but only to the extent set forth in the proviso
contained in Section 3(a)); 
 (b) prepare and file with the Commission such amendments and supplements to such
registration statement and the prospectus used in connection therewith as may be necessary to keep such registration statement effective for a period of not less than 180 days or such shorter period which will terminate when all Registrable
Securities covered by such registration statement have been sold (but not before the expiration of the 90-day period referred to in Section 4(3) of the Securities Act and Rule 174 thereunder, if applicable) and comply with the provisions of the
Securities Act with respect to the disposition of all securities covered by such registration statement during such period in accordance with the intended methods of disposition by the seller or sellers thereof set forth in such registration
statement; provided, however, that prior to filing with the Commission any such registration statement, prospectus or amendment or supplement thereto, the Company shall furnish copies thereof to counsel for the sellers of Registrable
Securities under such registration statement, which document will be subject to reasonably prompt review by such counsel; 
 (c) furnish to each seller of such Registrable Securities such number of copies of such registration statement and of each such amendment and supplement thereof (in each case including all exhibits), such number of copies of the prospectus
included in such registration statement (including each preliminary prospectus and summary prospectus), in conformity with the requirements of the Securities Act, and such other documents as such seller may reasonably request in order to facilitate
the disposition of the Registrable Securities by such seller; 
 (d) use its best efforts to register or qualify such
Registrable Securities covered by such registration statement under such other securities or blue sky laws of such jurisdictions as each seller shall request, and do any and all other acts and things which may be necessary or advisable to enable

 - 5 - 









 
of the Registrable Securities owned by such seller; provided, however, that the Company shall not be required to qualify generally to do
business in any jurisdiction where it is not then so qualified or to take any action which would subject it to general service of process in any such jurisdiction where it is not then so subject or subject itself to general taxation in any
jurisdiction where it is not then so subject; 
 (e) immediately notify each seller of any Registrable Securities covered by
such registration statement, at any time when a prospectus relating thereto is required to be delivered under the Act within the appropriate period mentioned in clause (b) of this Section 5, of the Company becoming aware that the
prospectus included in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the
light of the circumstances then existing, and within ten days prepare and furnish to all sellers a reasonable number of copies of an amended or supplemental prospectus as may be necessary so that, as thereafter delivered to the purchasers of such
Registrable Securities, such prospectus shall not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the
circumstances then existing; 
 (f) use its best efforts to list such Registrable Securities on any securities exchange on
which the Common Stock is then listed or NASDAQ if the Common Stock is then quoted on NASDAQ, if such Registrable Securities are not already so listed or quoted and if such listing is then permitted under the rules of such exchange or NASDAQ, and
provide an independent transfer agent and registrar for such Registrable Securities covered by such registration statement not later than the effective date of such registration statement; 
 The Company may require each seller of Registrable Securities as to which any registration is being effected promptly to furnish to the Company
(i) an opinion of counsel for such seller dated the effective date of the registration statement relating to such seller’s Registrable Securities (or, if such registration involves an underwritten Public Offering, dated the date of the
closing under the underwriting agreement), reasonably satisfactory in form and substance to the Company (and the managing underwriter, if any) and (ii) such information regarding the distribution of such Registrable Securities as may be legally
required. Such information shall be furnished in writing and shall state that it is being furnished for use in the registration statement. 
 Each holder of Registrable Securities agrees by acquisition of such Registrable Securities that, upon receipt of any notice from the Company of the happening of any event of the kind described in clause (e) of this Section 4, such
holder will forthwith discontinue disposition of Registrable Securities pursuant to the registration statement covering such Registrable Securities until such holder’s receipt of the supplemented or amended prospectus contemplated by clause
(e) of this Section 4, and, if so directed by the Company, such holder will deliver to the Company (at the Company’s expense) all copies, other than permanent file copies then in such holder’s possession, of the prospectus
covering such Registrable Securities current at the time of receipt of the Company’s notice. In the event the Company shall give any such notice, the period mentioned in clause (b) of this Section 4 shall be extended by the number of
days during the period from and including the date of the giving of such notice pursuant to clause 

  

 - 6 - 









 
(e) of this Section 4 and including the date when each seller of Registrable Securities covered by such registration statement shall have received the
copies of the supplemented or amended prospectus contemplated by clause (e) of this Section 4. 
 5. Indemnification.

 (a) Indemnification by the Company. The Company hereby agrees to indemnify and hold harmless each holder of
Registrable Securities which shall have been registered under the Securities Act, and such holder’s officers, directors, employees and agents and each other Person, if any, who controls such holder within the meaning of the Securities Act and
each other Person (including underwriters) who participates in the offering of such Registrable Securities against any losses, claims, damages, liabilities, reasonable attorneys’ fees, costs or expenses (collectively, the
“Damages”), joint or several, to which such holder or controlling Person or participating Person may become subject under the Securities Act or otherwise, insofar as such Damages (or proceedings in respect thereof) arise out of or
are based upon any untrue statement or alleged untrue statement of any material fact made by the Company or its agents contained in any registration statement under which such Registrable Securities are registered under the Securities Act, in any
preliminary prospectus or final prospectus contained therein, or in any amendment or supplement thereof, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary
to make the statements therein not misleading, and will reimburse such holder of Registrable Securities or such controlling Person or participating Person in connection with investigating or defending any such Damages or proceeding; provided,
however, that the Company will not be liable in any such case to the extent that any such Damages arise out of or are based upon (i) an untrue statement or alleged untrue statement or omission or alleged omission made in such
registration statement, said preliminary or final prospectus or said amendment or supplement thereto in reliance upon and in conformity with written information furnished to the Company by such holder or such controlling or participating Person, as
the case may be, specifically for use in the preparation thereof; or (ii) an untrue statement or alleged untrue statement, omission or alleged omission in a prospectus if such untrue statement or alleged untrue statement, omission or alleged
omission is corrected in an amendment or supplement to the prospectus which amendment or supplement is delivered to such holder in a timely manner and such holder thereafter fails to deliver such prospectus as so amended or supplemented prior to or
concurrently with the sale of such Registrable Securities to the Person asserting such Damages. 
 (b) Indemnification by
the Holders of Registrable Securities Which Are Registered. It shall be a condition of the Company’s obligations under this Agreement to effect any registration under the Securities Act that there shall have been delivered to the Company an
agreement or agreements duly executed by each holder of Registrable Securities to be so registered, whereby each such holder agrees to indemnify and hold harmless the Company, its directors, officers, employees and agents and each other Person, if
any, which controls the Company within the meaning of the Securities Act against any Damages, severally, but not jointly, to which the Company, or such other Person or such Person controlling the Company may become subject under the Securities Act
or otherwise, but only to the extent that such Damages (or proceedings in respect thereof) arise out of or are based upon any untrue statements or alleged untrue statement of any material fact contained, on the effective date thereof, in any 

  

 - 7 - 









 
registration statement under which such Registrable Securities are registered under the Securities Act, in any preliminary prospectus or final prospectus
contained therein or in any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not
misleading, which, in each such case, has been made in or omitted from such registration statement, said preliminary or final prospectus or said amendment or supplement in reliance upon, and in conformity with, written information furnished to the
Company by such holder of Registrable Securities specifically for use in the preparation thereof. The Company shall be entitled to receive indemnities from underwriters, selling brokers, dealer managers and similar securities industry professionals
participating in the distribution, to the same extent as provided above, with respect to information furnished in writing by such Persons specifically for inclusion in any prospectus or registration statement. 
 (c) Conduct of Indemnification Proceedings. Any Person entitled to indemnification hereunder shall (i) give prompt written
notice to the indemnifying party of the commencement of any action or proceeding involving a claim referred to in the preceding paragraphs of this Section 6 (provided the failure of any indemnified party to give such notice shall not relieve
the indemnifying party of its obligations under this Section 6 except to the extent of any damages caused solely by such failure), and (ii) unless the indemnified party has been advised by its counsel that a conflict of interest exists or
may exist between such indemnified and indemnifying parties under applicable standards of professional responsibility, with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably
satisfactory to the indemnified party. Whether or not such defense is assumed by the indemnifying party, the indemnifying party will not be subject to any liability for any settlement made without its consent (but such consent will not be
unreasonably withheld). No indemnifying party will consent to the entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a
release from all liability in respect of such claim or litigation; provided, however, that no indemnifying party will consent to the entry of any judgment or enter into any settlement (other than for the payment of money only) without
the consent of the indemnified party (which consent will not be unreasonably withheld). An indemnifying party who is not entitled to, or elects not to, assume the defense of the claim, will not be obligated to pay the fees and expenses of more than
one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest exists or may exist between such indemnified party and any other such
indemnified parties with respect to such claim, in which event the indemnifying party shall be obligated to pay the fees and expenses of such additional counsel or counsels. 
 (d) Contribution. If for any reason the indemnification provided for in the preceding Sections 5(a) or 5(b) is unavailable to an
indemnified party in respect of any Damages referred to therein, the indemnifying party shall contribute to the amount paid or payable by the indemnified party as a result of such Damages in such proportion as is appropriate to reflect the relative
benefits received by, and the relative fault of, the indemnified party and the indemnifying party, as well as any other appropriate equitable considerations; provided, however, that in no event shall the liability of any selling holder
of Registrable Securities hereunder (whether in respect of indemnification or contribution obligations) be greater in amount than the difference between the dollar amount of the proceeds received by such holder 

  

 - 8 - 









 
upon the sale of the Registrable Securities giving rise to such contribution obligation and all amounts previously contributed by such holder with respect to
such Damages. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of fraudulent misrepresentation. 
 6. Hold-Back Agreements. Each holder of Registrable Securities whose Registrable Securities are eligible for inclusion in a Registration Statement
filed pursuant to Section 3 agrees, if requested by the managing underwriter or underwriters in an Underwritten Offering of any Registrable Securities, not to effect any public sale or distribution of Registrable Securities, including a sale
pursuant to Rule 144 (or any similar provision then in force) under the Securities Act (except as part of such Underwritten Registration), during the 10-day period prior to, and for a period of up to 180-days (as required by the managing underwriter
in its reasonable discretion) beginning on the effective date of such Registration Statement, to the extent timely notified of such offering in writing by the Company or the managing underwriter or underwriters. 
 7. Underwritten Registration. 
 If
any of the Registrable Securities covered by any Incidental Registration are to be sold in an Underwritten Offering, the investment banker or investment bankers and manager or managers that will administer and underwrite the offering will be
selected by the Company. 
 Notwithstanding anything herein to the contrary, no Person may participate in any Underwritten Registration
hereunder unless such Person (a) agrees to sell such Person’s securities on the basis provided in any underwritten arrangements approved by the Persons entitled hereunder to approve such arrangement and (b) accurately completes and
executes all questionnaires, powers of attorney, indemnities, custody agreements, underwriting agreements and other customary documents required under the terms of such underwriting arrangements; provided, however, that no holder of
Registrable Securities will be required to provide representations and warranties or indemnities or otherwise become subject to liabilities or obligations in any such underwriting agreement that are not customary for investors of its type in such
transaction. 
 8. Miscellaneous. 
 (a) Effective Time. The provisions of Sections 2, 3, 4, 5, 6 and 7 of this Agreement shall be effective from and after the Effective Time. The provisions of Section 1 and this Section 8 are effective
from and after the date hereof 
 (b) Amendment and Modification. Prior to the Effective Time, this Agreement may be
amended or modified, or any provision hereof may be waived, provided, however, that such amendment, modification or waiver is set forth in a writing executed by the parties hereto, provided, further, however, that
in the event of a breach or default by one or more of the Management Investors hereunder, an amendment hereto need not be signed by such Management Investor to be effective if such Management Investor will no longer be a party to the Agreement after
giving effect to such amendment. From and after the Effective Time, this Agreement may be amended or modified, or any provision hereof may be waived, provided that 

  

 - 9 - 









 
such amendment or waiver is set forth in a writing executed by (i) the Company, (ii) the Required Holders (as defined in the Securities Holders
Agreement) and (iii) in the case of any amendment which materially and adversely affects any Investor differently from any other Investor (other than due to any difference in the number of shares owned by any such Investor), such Investor. No
course of dealing between or among any persons having any interest in this Agreement will be deemed effective to modify, amend or discharge any part of this Agreement or any rights or obligations of any person under or by reason of this Agreement.

 (c) Additional Parties. The Board of Directors of the Company shall be entitled, but not obligated, with the consent
of Person(s) holding at least 70% of the Registrable Securities, to allow any purchaser or acquirer of equity securities (or securities or rights convertible or exercisable into equity securities), of the same type and class of the Registrable
Securities, to execute a counterpart to this Agreement and become a party hereto (each, an “Additional Party”), in which case the equity securities issued or issuable to any such Additional Party shall be deemed to be
“Registrable Securities” subject to the terms and conditions hereof and such Additional Party shall be deemed to be a holder of “Registrable Securities” for purposes hereof. Except as set forth in this Section 8(b), the
Company will not grant to any other persons any registration rights. 
 (d) Survival of Representations and Warranties.
All representations, warranties, covenants and agreements set forth in this Agreement will survive the execution and delivery of this Agreement and the consummation of the transactions contemplated hereby, regardless of any investigation made by an
Investor or on its behalf. 
 (e) Successors and Assigns. This Agreement and all of the provisions hereof shall be
binding upon and inure to the benefit of the parties hereto and their respective successors and permitted assigns and executors, administrators and heirs. 
 (f) Separability. In the event that any provision of this Agreement or the application of any provision hereof is declared to be illegal, invalid or otherwise unenforceable by a court of competent jurisdiction,
the remainder of this Agreement shall not be affected except to the extent necessary to delete such illegal, invalid or unenforceable provision unless that provision held invalid shall substantially impair the benefits of the remaining portions of
this Agreement. 
 (g) Notices. All notices provided for or permitted hereunder shall be made in writing by
hand-delivery, registered or certified first-class mail, fax or reputable courier guaranteeing overnight delivery to the other party at the following addresses (or at such other address as shall be given in writing by any party to the others):
