2. Subject to the terms and conditions herein set forth, (a) the Company agrees to issue and sell to each of the Purchasers, and each of the Purchasers agrees, severally and not jointly, to
purchase from the Company, at a purchase price of 97.50% of the principal amount (the “Purchase Price”), plus accrued interest, if any, from March 6, 2017 to the first Time of Delivery (as defined in
Section 4 hereof), the principal amount of Securities set forth opposite the name of such Purchaser in Schedule I hereto, and (b) in the event and to the extent that the Representatives on behalf of the Purchasers shall exercise the
election to purchase Optional Securities as provided below, the Company agrees to issue and sell to each of the Purchasers, and each of the Purchasers agrees, severally and not jointly, to purchase from the Company, at the Purchase Price set forth
in clause (a) of this Section 2, that portion of the aggregate principal amount of the Optional Securities as to which such election shall have been exercised (to be adjusted by the Purchasers so as to eliminate fractions of $1,000),
determined by multiplying such aggregate principal amount of Optional Securities by a fraction, the numerator of which is the maximum aggregate principal amount of Optional Securities that such Purchaser is entitled to purchase as set forth opposite
the name of such Purchaser in Schedule I hereto and the denominator of which is the maximum aggregate principal amount of Optional Securities that all of the Purchasers are entitled to purchase hereunder. 

The Company hereby grants to the Purchasers the right to purchase at their option up to $40,000,000 aggregate principal amount of Optional Securities, solely
to cover over-allotments, at the purchase price set forth in clause (a) of the first paragraph of this Section 2 plus accrued interest, if any, from March 6, 2017 to such Subsequent Time of Delivery (as defined in Section 4
hereof). Any such election to purchase Optional Securities may be exercised by written notice from the Representatives on behalf of the Purchasers to the Company, given within a period of 30 calendar days from the date of this Agreement, setting
forth the aggregate principal amount of Optional Securities to be purchased and the date on which such Optional Securities are to be delivered, as determined by the Representatives but in no event earlier than the First Time of Delivery or, unless
the Representatives and the Company otherwise agree in writing, earlier than three or later than ten New York Business Days (as defined below) after the date of such notice. 

3. Upon the authorization by the Representatives of the release of the Securities, the several Purchasers propose to offer the Securities for sale upon the
terms and conditions set forth in this Agreement and the Offering Memorandum and each Purchaser, acting severally and not jointly, hereby represents and warrants to, and agrees with the Company that: 

(a) it will sell the Securities only to persons whom it reasonably believes are “qualified institutional buyers” (“QIBs”) within
the meaning of Rule 144A under the Securities Act in transactions meeting the requirements of Rule 144A; 
 (b) It is a QIB within the meaning of Rule 144A
under the Securities Act or an Institutional Accredited Investor, within the meaning of Rule 501(a) under the Securities Act; and 
 (c) Neither it nor any
of its affiliates or any other person acting on its or their behalf will solicit offers for, or offer or sell, the Securities by means of any form of general solicitation or general advertising within the meaning of Rule 502(c) of Regulation D or in
any manner involving a public offering within the meaning of Section 4(a)(2) of the Securities Act (other than by means of a Permitted General Solicitation, as defined below). 

4. (a) The Securities to be purchased by each Purchaser hereunder will be represented by one or more definitive global Securities in book-entry form which
will be deposited by or on behalf of the Company with The Depository Trust Company (“DTC”) or its designated custodian. The Company will deliver the Securities to the Representatives, for the account of each Purchaser, against
payment by or on behalf of such Purchaser of the purchase price therefor by wire transfer of Federal (same day) funds, by causing DTC to credit the Securities to the account of Goldman, Sachs & Co. at DTC. The Company will cause the
certificates representing the Securities to be made available to the Representatives for checking at least twenty-four hours prior to each Time of Delivery (as defined below) at the office of Simpson Thacher & Bartlett LLP, 2475 Hanover
Street, Palo Alto, California 94304 (the “Closing Location”). The time and date of such delivery and payment shall be 9:30 a.m., New York City time, on March 6, 2017 or such other time and date as the Representatives and the
Company may agree upon in writing, and with respect to the Optional Securities, 9:30 a.m. New York City time, on the date specified by the Representatives in the written notice given by the Representatives of the Purchasers’ election to
purchase such Optional Securities, or such other time and date as the Representatives and the Company may agree upon in writing; provided, however, that such delivery date must be at least three New York Business Days (as defined below) after


  
 9 








 
such written notice is given and may not be earlier than the First Time of Delivery (as defined below) nor later than ten New York Business Days (as defined below) after the date of such notice;
provided further, that solely with respect to an Optional Securities written notice that is delivered prior to the First Time of Delivery, the related Time of Delivery (as defined below) must be at least one New York Business Day after the written
notice is given. Such time and date for delivery of the Firm Securities are herein called the “First Time of Delivery”, any such time and date for delivery of the Optional Securities, if not the First Time of Delivery, are
herein called a “Subsequent Time of Delivery”, and each such time and date for delivery are herein called a “Time of Delivery”. 

(b) The documents to be delivered at each Time of Delivery by or on behalf of the parties hereto pursuant to Section 8 hereof, including the
cross-receipt for the Securities and any additional documents requested by the Purchasers pursuant to Section 8(k) hereof, will be delivered at such time and date at the Closing Location, and the Securities will be delivered at the office of DTC (or
its designated custodian), all at such Time of Delivery. A meeting will be held at the Closing Location at 5:00 p.m., New York City time, on the New York Business Day next preceding such Time of Delivery, at which meeting the final drafts of the
documents to be delivered pursuant to the preceding sentence will be available for review by the parties hereto. For the purposes of this Section 4, “New York Business Day” shall mean each Monday, Tuesday, Wednesday, Thursday
and Friday which is not a day on which banking institutions in New York are generally authorized or obligated by law or executive order to close. 
 5. The
Company agrees with each of the Purchasers: 
 (a) To prepare the Offering Memorandum in a form approved by the Representatives; to make no amendment or any
supplement to the Offering Memorandum which shall be disapproved by the Representatives promptly after reasonable notice thereof; and to furnish the Representatives with copies thereof; 

(b) Promptly from time to time to take such action as the Representatives may reasonably request to qualify the Securities and the Underlying Shares for
offering and sale under the securities laws of such jurisdictions as you may reasonably request and to comply with such laws so as to permit the continuance of sales and dealings therein in such jurisdictions for as long as may be necessary to
complete the distribution of the Securities, provided that in connection therewith the Company shall not be required to qualify as a foreign corporation or to file a general consent to service of process in any jurisdiction or subject itself to
taxation in such jurisdiction in which it was not otherwise subject to taxation as a foreign corporation; 
 (c) To furnish the Purchasers with written and
electronic copies of the Offering Memorandum and any amendment or supplement thereto in such quantities as the Representatives may from time to time reasonably request, and if, at any time prior to the completion of the distribution of the
Securities, any event shall have occurred as a result of which the Offering Memorandum as then amended or supplemented would include an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements
therein, in the light of the circumstances under which they were made when such Offering Memorandum is delivered, not misleading, or, if for any other reason it shall be necessary during such same period to amend or supplement the Offering
Memorandum, to notify the Representatives and upon the request of the Representatives to prepare and furnish without charge to each Purchaser and to any dealer in securities (whose name and address the Purchasers shall furnish to the Company) as
many written and electronic copies as the Representatives may from time to time reasonably request of an amended Offering Memorandum or a supplement to the Offering Memorandum which will correct such statement or omission or effect such compliance;
and furthermore, if the Pricing Memorandum is being used to solicit offers to buy the Securities at a time when the Offering Memorandum is not yet available to prospective purchasers and any event shall occur or condition exist as a result of which
it is necessary to amend or supplement the Pricing Memorandum in order to make the statements therein, in light of the circumstances, not misleading, or if, in the opinion of counsel for the Purchasers, it is necessary to amend or supplement the
Pricing Memorandum to comply with applicable law, forthwith to prepare and furnish, at its own expense, to the Purchasers and to any dealer upon request, either amendments or supplements to the Pricing Memorandum so that the statements in the
Pricing Memorandum as so amended or supplemented will not, in light of the circumstances when delivered to a prospective purchaser, be misleading or so that the Pricing Memorandum, as amended or supplemented, will comply with applicable law; 

(d) During the period beginning from the date hereof and continuing until the date that is 60 days after the date of the Offering Memorandum, without the
prior written consent of Goldman, Sachs & Co. and J.P. Morgan Securities LLC, not to (i) offer, issue, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option,

otherwise than as set forth or contemplated in the Pricing Memorandum, the effect of which, in any such case described in clause (i) or (ii), is in the judgment of the Representatives so material and adverse as to make it impracticable or

such Time of Delivery on the terms and in the manner contemplated in the Pricing Disclosure Package and the Offering Memorandum; 
 (f) The Underlying
Shares shall have been duly listed, subject to notice of issuance, on the New York Stock Exchange;

prior to such Time of Delivery, as to the matters set forth in subsection (d) of this Section and as to such other matters as the Representatives may reasonably request. 

9. (a) The Company will indemnify and hold harmless each Purchaser against any losses, claims, damages or liabilities, joint or several, to which such
Purchaser may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material
fact contained in any Preliminary Offering Memorandum, the Pricing Memorandum, the Pricing Disclosure Package, the Offering Memorandum, or any amendment or supplement thereto, any Company Supplemental Disclosure Document, any Permitted General
Solicitation Material or arise out of or are based upon the omission or alleged omission to state therein a material fact necessary to make the statements therein not misleading, and will reimburse each Purchaser for any legal or other expenses
reasonably incurred by such Purchaser in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the Company shall not be liable in any such case to the extent that any such loss,
claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in any Preliminary Offering Memorandum, the Pricing Memorandum, the Pricing Disclosure Package, the
Offering Memorandum or any amendment or supplement thereto, any Company Supplemental Disclosure Document or any Permitted General Solicitation Material, in reliance upon and in conformity with written information furnished to the Company by any
Purchaser through the Representatives expressly for use therein. 
 (b) Each Purchaser, severally and not jointly, will indemnify and hold harmless the
Company against any losses, claims, damages or liabilities to which the Company may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are
based upon an untrue statement or alleged untrue statement of a material fact contained in any Preliminary Offering Memorandum, the Pricing Memorandum, the Pricing Disclosure Package, the Offering Memorandum, or any amendment or supplement thereto,
or any Company Supplemental Disclosure Document, any Permitted General Solicitation Material or arise out of or are based upon the omission or alleged omission to state therein a material fact necessary to make the statements therein not misleading,
in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in any Preliminary Offering Memorandum, the Pricing Memorandum, the Pricing Disclosure Package, the
Offering Memorandum or any such amendment or supplement, any Company Supplemental Disclosure Document or any Permitted General Solicitation Material, in reliance upon and in conformity with written information furnished to the Company by such
Purchaser through the Representatives expressly for use therein; and each Purchaser will reimburse the Company for any legal or other expenses reasonably incurred by the Company in connection with investigating or defending any such action or claim
as such expenses are incurred. 
 (c) Promptly after receipt by an indemnified party under subsection (a) or (b) of this Section 9 of notice of
the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so
to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party under such subsection unless and to the extent it has been materially prejudiced through the forfeiture by the indemnified party of
substantial rights and defenses. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to
the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified
party, be counsel to the indemnifying 

  
 14 








 
party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified
party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. No
indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which
indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the
indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act, by or on behalf of any indemnified party. 

(d) If the indemnification provided for in this Section 9 is unavailable to or insufficient to hold harmless an indemnified party under subsection
(a) or (b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of
such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Purchasers on the other from the offering of the
Securities. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under subsection (c) above, then each indemnifying party
shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company on the one hand and the Purchasers on the other in
connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company on the
one hand and the Purchasers on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total discounts and commissions received by the
Purchasers, in each case as set forth in the Offering Memorandum. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to
state a material fact relates to information supplied by the Company on the one hand or the Purchasers on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or
omission. The Company and the Purchasers agree that it would not be just and equitable if contribution pursuant to this subsection (d) were determined by pro rata allocation (even if the Purchasers were treated as one entity for such purpose)
or by any other method of allocation which does not take account of the equitable considerations referred to above in this subsection (d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities
(or actions in respect thereof) referred to above in this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or
claim. Notwithstanding the provisions of this subsection (d), no Purchaser shall be required to contribute any amount in excess of the amount by which the total price at which the Securities purchased by it pursuant to this Agreement and distributed
to investors were offered to investors exceeds the amount of any damages which such Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. The Purchasers’ obligations
in this subsection (d) to contribute are several in proportion to their respective purchase obligations and not joint. 
 (e) The obligations of the
Company under this Section 9 shall be in addition to any liability which the Company may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of each Purchaser and each person, if any, who controls
any Purchaser within the meaning of the Securities Act and each affiliate of each Purchaser; and the obligations of the Purchasers under this Section 9 shall be in addition to any liability which the respective Purchasers may otherwise have and
shall extend, upon the same terms and conditions, to each officer and director of the Company and to each person, if any, who controls the Company within the meaning of the Securities Act. 

10. (a) If any Purchaser shall default in its obligation to purchase the Securities which it has agreed to purchase hereunder, the Representatives may in
their discretion arrange for the Representatives or another party or other parties to purchase such Securities on the terms contained herein at the applicable Time of Delivery. If within thirty-six hours after
such default by any Purchaser the Representatives do not arrange for the purchase of such Securities, then the Company shall be entitled to a further period of thirty-six hours within which to procure another
party or other parties reasonably satisfactory to the Representatives to purchase such Securities on such terms. In the event 

  
 15 








 
that, within the respective prescribed periods, the Representatives notify the Company that the Representatives have so arranged for the purchase of such Securities, or the Company notifies the
Representatives that it has so arranged for the purchase of such Securities, the Representatives or the Company shall have the right to postpone such Time of Delivery for a period of not more than seven days, in order to effect whatever changes may
thereby be made necessary in the Offering Memorandum, or in any other documents or arrangements, and the Company agrees to prepare promptly any amendments or supplements to the Offering Memorandum which in the opinion of the Representatives may
thereby be made necessary. The term “Purchaser” as used in this Agreement shall include any person substituted under this Section with like effect as if such person had originally been a party to this Agreement with respect to such
Securities. 
 (b) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Purchaser or Purchasers by the
Representatives and the Company as provided in subsection (a) above, the aggregate principal amount of such Securities which remains unpurchased does not exceed one-eleventh of the aggregate principal
amount of all the Securities to be purchased at such Time of Delivery, then the Company shall have the right to require each non-defaulting Purchaser to purchase the principal amount of Securities which such
Purchaser agreed to purchase hereunder at such Time of Delivery and, in addition, to require each non-defaulting Purchaser to purchase its pro rata share (based on the principal amount of Securities which such
Purchaser agreed to purchase hereunder) of the Securities of such defaulting Purchaser or Purchasers for which such arrangements have not been made; but nothing herein shall relieve a defaulting Purchaser from liability for its default. 

(c) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Purchaser or Purchasers by the Representatives and the
Company as provided in subsection (a) above, the aggregate principal amount of Securities which remains unpurchased exceeds one-eleventh of the aggregate principal amount of all the Securities to be
purchased at such Time of Delivery, or if the Company shall not exercise the right described in subsection (b) above to require non-defaulting Purchasers to purchase Securities of a defaulting Purchaser
or Purchasers, then this Agreement (or, with respect to a Subsequent Time of Delivery, the obligation of the Purchasers to purchase and of the Company to sell the Optional Securities) shall thereupon terminate, without liability on the part of any non-defaulting Purchaser or the Company, except for the expenses to be borne by the Company and the Purchasers as provided in Section 7 hereof and the indemnity and contribution agreements in Section 9
hereof; but nothing herein shall relieve a defaulting Purchaser from liability for its default. 
 11. The respective indemnities, agreements,
representations, warranties and other statements of the Company and the several Purchasers, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless
of any investigation (or any statement as to the results thereof) made by or on behalf of any Purchaser or any controlling person of any Purchaser, or the Company, or any officer or director or controlling person of the Company, and shall survive
delivery of and payment for the Securities. 
 12. If this Agreement shall be terminated pursuant to Section 10 hereof, the Company shall not then be
under any liability to any Purchaser except as provided in Sections 7 and 9 hereof; but, if for any other reason, the Securities are not delivered by or on behalf of the Company as provided herein, the Company will reimburse the Purchasers through
the Representatives for all documented out-of-pocket expenses approved in writing by the Representatives, including fees and disbursements of counsel, reasonably
incurred by the Purchasers in making preparations for the purchase, sale and delivery of the Securities, but the Company shall then be under no further liability to any Purchaser except as provided in Sections 7 and 9 hereof. 

13. In all dealings hereunder, the Representatives shall act on behalf of each of the Purchasers, and the parties hereto shall be entitled to act and rely
upon any statement, request, notice or agreement on behalf of any Purchaser made or given by you as the Representatives. 
 All statements, requests,
notices and agreements hereunder shall be in writing, and if to the Purchasers shall be delivered or sent by mail or facsimile transmission to the Representatives c/o Goldman, Sachs & Co., 200 West Street, New York, New York 10282-2198,
Attention: Registration Department; and J.P. Morgan Securities LLC, 383 Madison Avenue, New York, New York 10179, Attention: Equity/Converts Syndicate Desk; and if to the Company shall be delivered or sent by mail or facsimile transmission to the
address of the Company set forth in the Offering Memorandum, Attention: General Counsel; and if to any stockholder that has delivered a lock-up letter described in Section 8(g) hereof shall be delivered or
sent by mail to his, her or its address as such stockholder 

  
 16 








 
provides in writing to the Company; provided, however, that any notice to a Purchaser pursuant to Section 9 hereof shall be delivered or sent by mail or facsimile transmission to such
Purchaser at its address set forth in its 
 Purchasers’ Questionnaire, which address will be supplied to the Company by the Representatives upon
request. Any such statements, requests, notices or agreements shall take effect upon receipt thereof. 
 In accordance with the requirements of the USA
Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Purchasers are required to obtain, verify and record information that identifies their respective clients, including the
Company, which information may include the name and address of their respective clients, as well as other information that will allow the Purchasers to properly identify their respective clients. 

14. This Agreement shall be binding upon, and inure solely to the benefit of, the Purchasers, the Company and, to the extent provided in Sections 9 and 11
hereof, the officers and directors of the Company and each person who controls the Company or any Purchaser, and their respective heirs, executors, administrators, successors and assigns, and no other person shall acquire or have any right under or
by virtue of this Agreement. No purchaser of any of the Securities from any Purchaser shall be deemed a successor or assign by reason merely of such purchase. 

15. Time shall be of the essence of this Agreement. 
 16. The
Company acknowledges and agrees that (i) the purchase and sale of the Securities pursuant to this Agreement is an arm’s-length commercial transaction between the Company, on the one hand, and the
several Purchasers, on the other, (ii) in connection therewith and with the process leading to such transaction each Purchaser is acting solely as a principal and not the agent or fiduciary of the Company, (iii) no Purchaser has assumed an
advisory or fiduciary responsibility in favor of the Company with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Purchaser has advised or is currently advising the Company on other matters)
or any other obligation to the Company except the obligations expressly set forth in this Agreement and (iv) the Company has consulted its own legal and financial advisors to the extent it deemed appropriate. The Company agrees that it will not
claim that the Purchasers, or any of them, has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to the Company, in connection with such transaction or the process leading thereto. 

17. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company and the Purchasers, or any of them, with
respect to the subject matter hereof. 
 18. THIS AGREEMENT AND ANY MATTERS RELATED TO THIS TRANSACTION SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE
WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO PRINCIPLES OF CONFLICT OF LAWS THAT WOULD RESULT IN THE APPLICATION OF ANY LAW OTHER THAN THE LAWS OF THE STATE OF NEW YORK. The Company agrees that any suit or proceeding arising in respect
of this agreement or our engagement will be tried exclusively in the U.S. District Court for the Southern District of New York or, if that court does not have subject matter jurisdiction, in any state court located in the City and County of New York
and the Company agrees to submit to the jurisdiction of, and to venue in, such courts. 
 19. The Company and each Purchaser hereby irrevocably waives, to
the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby. 

20. This Agreement may be executed by any one or more of the parties hereto in any number of counterparts, each of which shall be deemed to be an original,
but all such respective counterparts shall together constitute one and the same instrument. 
 21. Notwithstanding anything herein to the contrary, the
Company (and the Company’s employees, representatives, and other agents) are authorized to disclose to any and all persons, the tax treatment and tax structure of the potential transaction and all materials of any kind (including tax opinions
and other tax analyses) provided to the Company relating to that treatment and structure, without the Purchasers’ imposing any limitation of any kind. 

  
 17 








 If the foregoing is in accordance with your understanding, please sign and return to us three counterparts
hereof, and upon the acceptance hereof by the Representatives, on behalf of each of the Purchasers, this letter and such acceptance hereof shall constitute a binding agreement among each of the Purchasers and the Company. It is understood that your
acceptance of this letter on behalf of each of the Purchasers is pursuant to the authority set forth in a form of Agreement among Purchasers, the form of which shall be submitted to the Company for examination upon request, but without warranty on
your part as to the authority of the signers thereof.
