the Initial Purchasers without registration under the Securities Act of 1933, as amended (the “Securities Act”), in reliance on an exemption pursuant to Section 4(a)(2) under the Securities Act. The Company has prepared a

terms of the Securities omitted from the Preliminary Offering Memorandum and certain other information and an offering memorandum, dated May 24, 2022 (the “Offering Memorandum”), setting forth information regarding the Company and
the Securities. The Preliminary Offering Memorandum, as supplemented and amended as of the Applicable Time (as defined below), together with the Pricing Term Sheet and any of the documents listed on Schedule III(A) hereto are collectively referred
to as the “Pricing Disclosure Package”. The Company hereby confirms that it has authorized the use of the Pricing Disclosure Package and the Offering Memorandum in connection with the offering and resale of the Securities by the
Initial Purchasers. “Applicable Time” means 7:00 p.m. (New York City time) on the date of this Agreement.

information and the integrity, operation, redundancy and security of all IT Systems and the security of all personal, personally identifiable, sensitive, or confidential data (“Personal Data”)) in their possession or operational
control that are used in connection with their businesses, and, to the knowledge of the Company, there have been no breaches or unauthorized uses of or accesses to the same. Except as would not reasonably be expected to have a Material Adverse
Effect, the Company and its subsidiaries are and have been in compliance with all applicable laws or statutes and all applicable judgments, orders, rules and regulations of any court or arbitrator or governmental or regulatory authority, and all of

would reasonably be expected to result in a judgment that the Company is or would become unable to satisfy. In computing the amount of such contingent liabilities at any time, it is intended that such liabilities will be computed at the amount that,
in the light of all the facts and circumstances existing at such time, represents the amount that can reasonably be expected to become an actual or matured liability. 

(ddd) No forward looking statement (within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act)
included or incorporated by reference in any of the Pricing Disclosure Package or the Offering Memorandum has been made or reaffirmed without a reasonable basis or has been disclosed other than in good faith. 

Any certificate signed by any officer of the Company and delivered to the Representatives or counsel for the Initial Purchasers in connection
with the offering of the Securities shall be deemed a representation and warranty by the Company, as to matters covered thereby, to each Initial Purchaser. 

3. Purchase of the Securities by the Initial Purchasers, Agreements to Sell, Purchase and Resell.(a) (a) The Company hereby agrees, on
the basis of the representations, warranties, covenants and agreements of the Initial Purchasers contained herein and subject to all the terms and conditions set forth herein, to issue and sell to the Initial Purchasers and, upon the basis of the
representations, warranties and agreements of the Company herein contained and subject to all the terms and conditions set forth herein, each Initial Purchaser agrees, severally and not jointly, to purchase from the Company, at a purchase price of
98% of the principal amount thereof (the “Purchase Price”), the total principal amount of Securities set forth opposite the name of such Initial Purchaser in Schedule I hereto. The Company shall not be obligated to deliver
any of the Securities to be delivered hereunder except upon payment for all of the Securities to be purchased as provided herein. 
 (b) On
the basis of the representations and warranties contained in this Agreement, and subject to its terms and conditions, the Company agrees to sell to the Initial Purchasers the Additional Securities, and the Initial Purchasers shall have the right to
purchase, severally and not jointly, up to $60,000,000 aggregate principal amount of Additional Securities at the Purchase Price, plus accrued interest, if any, from the Closing Date. The Representatives may exercise this right on behalf of the
Initial Purchasers in whole or from time to time in part by giving written notice not later than 13 days from, and including, one business day after the date of this Agreement; provided, any such written notice shall be delivered to the Company no
later than 12:00 PM, New York Time, on the business day immediately preceding the Option Closing Date (as defined below). Any exercise notice shall specify the principal amount of Additional Securities to be purchased by the Initial Purchasers and
the date on which such Additional Securities are to be purchased. Unless otherwise agreed to by the Company, each purchase date must be, in the case of any notice that is given prior to June 8, 2022, at least two business days after the
written notice is given; provided, however, that if an exercise notice is given (1) on or after June 8, 2022 or (2) on May 25, 2022, the corresponding purchase date must be one business day after the written notice
is given and, in any case, the purchase date for any Additional Securities may not be earlier than the Closing Date nor later than 13 days from, and including, the Closing Date. On each day, 

  
 15 












 
if any, that Additional Securities are to be purchased (an “Option Closing Date”), each Initial Purchaser agrees, severally and not jointly, to purchase the principal amount of
Additional Securities (subject to such adjustments to eliminate fractional Securities as you may determine) that bears the same proportion to the total principal amount of Additional Securities to be purchased on such Option Closing Date as the
principal amount of Firm Securities set forth in Schedule I opposite the name of such Initial Purchaser bears to the total principal amount of Firm Securities. 

(c) Each of the Initial Purchasers, severally and not jointly, hereby represents and warrants to the Company and agrees that it will offer the
Securities for sale upon the terms and conditions set forth in this Agreement and in the Pricing Disclosure Package. Each of the Initial Purchasers, severally and not jointly, hereby represents and warrants to, and agrees with, the Company, on the
basis of the representations, warranties and agreements of the Company, that such Initial Purchaser: (i) is a QIB with such knowledge and experience in financial and business matters as are necessary in order to evaluate the merits and risks of
an investment in the Securities; (ii) is purchasing the Securities pursuant to a private sale exempt from registration under the Securities Act; (iii) in connection with the Exempt Resales, will solicit offers to buy the Securities only
from, and will offer to sell the Securities only to, the Eligible Purchasers in accordance with this Agreement and on the terms contemplated by the Pricing Disclosure Package; and (iv) will not offer or sell the Securities pursuant to, nor has
it offered or sold the Securities by, or otherwise engaged in, any form of general solicitation or general advertising (within the meaning of Regulation D, including, but not limited to, advertisements, articles, notices or other communications
published in any newspaper, magazine, or similar medium or broadcast over television or radio, or any seminar or meeting whose attendees have been invited by any general solicitation or general advertising) and will not engage in any directed
selling efforts within the meaning of Rule 902 under the Securities Act, in connection with the offering of the Securities. The Initial Purchasers have advised the Company that they will offer the Securities to Eligible Purchasers at a price
initially equal to 100% of the principal amount thereof, plus accrued interest, if any, from the date of issuance of the Securities. Such price may be changed by the Initial Purchasers at any time without notice. 

(d) The Initial Purchasers have not nor, prior to the later to occur of (i) the Closing Date and (ii) completion of the distribution
of the Securities, will not, use, authorize use of, refer to or distribute any material in connection with the offering and sale of the Securities other than (A) the Preliminary Offering Memorandum, the Pricing Disclosure Package, the Offering
Memorandum, (B) any written communication that contains no “issuer information” (as defined in Rule 433(h)(2) under the Securities Act) that was not included (including through incorporation by reference) in the Preliminary Offering
Memorandum or any Free Writing Offering Document listed on Schedule III(B) hereto, (C) the Free Writing Offering Documents listed on Schedule III(B) hereto, (D) any written communication prepared by such
Initial Purchaser and approved by the Company in writing or (E) any written communication relating to or that contains the terms of the Securities and/or other information that was included (including through incorporation by reference) in the
Preliminary Offering Memorandum, the Pricing Disclosure Package or the Offering Memorandum.

and until such time as the same is no longer required under the applicable requirements of the Securities Act, the Securities (and all securities issued in exchange therefore or in substitution thereof) shall bear legends substantially in the forms
as set forth in the “Transfer Restrictions” section of the Pricing Disclosure Package and Offering Memorandum (along with such other legends as the Company and its counsel deem necessary). 

Each of the Initial Purchasers understands that the Company and, for purposes of the opinions to be delivered to the Initial Purchasers
pursuant to Sections 7(c), 7(d), 7(e) and 7(f) hereof, counsel to the Company and counsel to the Initial Purchasers, will rely upon the accuracy and truth of the foregoing representations, warranties and agreements, and the Initial Purchasers hereby

may be varied by agreement between the Initial Purchasers and the Company. 
 Payment for any Additional Securities shall be made to the
Company against delivery of such Additional Securities for the respective accounts of the several Initial Purchasers at 10:00 a.m., New York City time, on the date specified in the corresponding notice described in Section 3(b) or at such other

available funds, by causing DTC to credit the Securities to the account of the Initial Purchasers at DTC. The Securities will be evidenced by one or more global securities in definitive form (the “Global Securities”) and will be

Securities. 
 (d) If, at any time prior to completion of the distribution of the Securities by the Initial Purchasers to Eligible
Purchasers, any event occurs or information becomes known that, in the judgment of the Company or in the opinion of counsel for the Initial Purchasers, should be set forth in the Pricing Disclosure Package or the Offering Memorandum so that the
Pricing Disclosure Package or the Offering Memorandum, as then amended or supplemented, does not include any untrue statement of material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading, or if it is necessary to supplement or amend the Pricing Disclosure Package or the Offering Memorandum in order to comply with any law, the Company will as promptly as practicable prepare an
appropriate supplement or amendment thereto, and will as promptly as practicable furnish to the Initial Purchasers and dealers a reasonable number of copies thereof. 

(e) The Company will not make any offer to sell or solicitation of an offer to buy the Securities that would constitute a Free Writing
Offering Document without the prior consent of the Representatives, which consent shall not be unreasonably withheld, delayed or conditioned. If at any time following issuance of a Free Writing Offering Document any event occurred or occurs as a
result of which such Free Writing Offering Document conflicts with the information in the Preliminary Offering Memorandum, the Pricing Disclosure Package or the Offering Memorandum or, when taken together with the information in the Preliminary
Offering Memorandum, the Pricing Disclosure Package or the Offering Memorandum, includes an untrue statement of a material fact or omits to state any material fact necessary in order to make the statements therein, in the light of the circumstances
then existing, not misleading, as promptly as practicable after becoming aware thereof, the Company will give notice thereof to the Initial Purchasers through the Representatives and, if requested by the Representatives, will prepare and furnish
without charge to each Initial Purchaser a Free Writing Offering Document or other document that will correct such conflict, statement or omission. 

(f) Promptly from time to time to take such action as the Initial Purchasers may reasonably request to qualify the Securities and Underlying

jurisdictions for as long as may be necessary to complete the distribution of the Securities and the Underlying Securities; provided that in connection therewith the Company shall not be required to (i) qualify as a foreign corporation
in any jurisdiction in which it would not otherwise be required to so qualify, (ii) file a general consent to service of process in any such jurisdiction or (iii) subject itself to taxation in any jurisdiction in which it would not
otherwise be subject.

 18 












 
or other derivatives transaction that transfers to another, in whole or in part, any of the economic benefits or risks of ownership of such shares of Common Stock, whether any such transaction

of any shares of Common Stock or securities convertible, exercisable or exchangeable into Common Stock or any other securities of the Company (other than any registration statement on Form S-8) or

forth on Schedule IV hereto to furnish to the Representatives, prior to the date of this Agreement, a letter or letters, substantially in the form of Exhibit A hereto (the “Lock-Up
Agreements”); provided that the foregoing restrictions shall not apply to (1) the sale of the Securities under this Agreement or the issuance of any Underlying Securities, (2) the grant of options and other equity awards
pursuant to employee benefit plans, qualified stock option plans, other employee compensation plans or non-employee director compensation programs existing on the date hereof and disclosed in the Pricing

(h) So long as any of the Securities or the Underlying Securities are outstanding, the Company will furnish at its expense to the Initial
Purchasers, and, upon request, to the holders of the Securities or the Underlying Securities and prospective purchasers of the Securities or the Underlying Securities the information required by Rule 144A(d)(4) (if any).

description set forth in the Pricing Disclosure Package and the Offering Memorandum under the caption “Use of Proceeds.”

Company in connection with the offering of the Securities.

Underlying Securities to be eligible for clearance and settlement through DTC. 
 (l) The Company will not, and, for so long as the
restrictive legend on the Securities has not been removed by the Company, will not permit any of its affiliates (as defined in Rule 144) to, (A) resell any of the Securities that have been acquired by any of them, except for Securities
purchased by the Company or any of its affiliates and resold in a transaction registered under the Securities Act or pursuant to any exemption under the Securities Act that results in such Securities not being “restricted securities”

 19 












 (m) The Company agrees not to sell, offer for sale or solicit offers to buy or otherwise
negotiate in respect of any security (as defined in the Securities Act) that would be integrated with the sale of the Securities in a manner that would require the registration under the Securities Act of the sale to the Initial Purchasers or the
Eligible Purchasers of the Securities. The Company will take reasonable precautions designed to insure that any offer or sale, direct or indirect, in the United States or to any U.S. person (as defined in Rule 902 under the Securities Act), of any
Securities or any substantially similar security issued by the Company, within six months subsequent to the date on which the distribution of the Securities has been completed (as notified to the Company by the Initial Purchasers), is made under
restrictions and other circumstances reasonably designed not to affect the status of the offer and sale of the Securities in the United States and to U.S. persons contemplated by this Agreement as transactions exempt from the registration provisions
of the Securities Act, including any sales pursuant to Rule 144A or Regulations D or S of the Securities Act. 
 (n) The Company agrees to

aggregate, in the judgment of the Representatives, so material and adverse as to make it impracticable or inadvisable to proceed with the offering or the delivery of the Securities being delivered on the Closing Date on the terms and in the manner
contemplated in the Pricing Disclosure Package and the Offering Memorandum. 
 (j) The Company shall have furnished or caused to be

to make the statements therein, in the light of the circumstances under which they were made, not misleading and (B) since the date of the Pricing Disclosure Package and the Offering Memorandum, no event has occurred which should have been set

Securities being delivered on the Closing Date on the terms and in the manner contemplated in the Offering Memorandum, (v) a downgrading in the rating accorded the Company’s debt securities by any “nationally recognized statistical

the delivery to the Representatives on the applicable Option Closing Date of such documents as the Representatives may reasonably request with respect to the good standing of the Company, the due authorization and issuance of the Additional
Securities to be sold on such Option Closing Date and other matters related to the issuance of such Additional Securities. 
 All letters,

8. Indemnification and Contribution. 

(a) The Company hereby agrees to indemnify and hold harmless each Initial Purchaser, its affiliates, directors, officers and employees and
each person, if any, who controls any Initial Purchaser within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any loss, claim, damage or liability, joint or several, or any action in
respect thereof (including, but not limited to, any loss, claim, damage, liability or action relating 

  
 24 












 
to purchases and sales of Securities), to which that Initial Purchaser, affiliate, director, officer, employee or controlling person may become subject, under the Securities Act or otherwise,
insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained (A) in any Free Writing Offering Document, the Preliminary Offering
Memorandum, the Pricing Disclosure Package or the Offering Memorandum or in any amendment or supplement thereto, (B) in any Blue Sky application or other document prepared or executed by the Company (or based upon any written information
furnished by the Company) specifically for the purpose of qualifying any or all of the Securities under the securities laws of any state or other jurisdiction (any such application, document or information being hereinafter called a “Blue
Sky Application”) or (C) in any materials or information provided to investors by, or with the approval of, the Company in connection with the marketing of the offering of the Securities (“Marketing Materials”),
including any road show or investor presentations made to investors by the Company (whether in person or electronically), or (ii) the omission or alleged omission to state in any Free Writing Offering Document, the Preliminary Offering
Memorandum, the Pricing Disclosure Package or the Offering Memorandum, or in any amendment or supplement thereto, or in any Blue Sky Application or in any Marketing Materials, any material fact necessary in order to make the statements therein, in
the light of the circumstances under which they were made, not misleading, and shall reimburse each Initial Purchaser and each such affiliate, director, officer, employee or controlling person promptly upon demand for any legal or other expenses
reasonably incurred by that Initial Purchaser, affiliate, director, officer, employee or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action 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, liability or action arises out of, or is based upon, any untrue statement or alleged
untrue statement or omission or alleged omission made in any Preliminary Offering Memorandum, the Pricing Disclosure Package or Offering Memorandum, or in any such amendment or supplement thereto, or in any Blue Sky Application or in any Marketing
Materials, in reliance upon and in conformity with written information concerning such Initial Purchaser furnished to the Company through the Representatives by or on behalf of any Initial Purchaser specifically for inclusion therein, which
information consists solely of the information specified in Section 8(e). The foregoing indemnity agreement is in addition to any liability that the Company may otherwise have to any Initial Purchaser or to any affiliate, director, officer,
employee or controlling person of that Initial Purchaser. 
 (b) Each Initial Purchaser, severally and not jointly, hereby agrees to
indemnify and hold harmless the Company, its officers and employees, each of its directors, and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from
and against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which the Company or any such director, officer, employee or controlling person may become subject, under the Securities Act or otherwise,
insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained (A) in any Free Writing Offering Document, Preliminary Offering
Memorandum, the Pricing Disclosure Package or the Offering Memorandum or in any amendment or supplement thereto, (B) in any Blue Sky Application or (C) in any Marketing Materials, or (ii) the omission or alleged omission to state in
any Free Writing Offering Document, Preliminary Offering Memorandum, the Pricing Disclosure Package or the Offering Memorandum, or in any amendment or supplement thereto, or in any Blue Sky Application or in


  
 25 












 
any Marketing Materials any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, but in each case only to
the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information concerning such Initial Purchaser furnished to the Company through the
Representatives by or on behalf of that Initial Purchaser specifically for inclusion therein, which information is limited to the information set forth in Section 8(e). The foregoing indemnity agreement is in addition to any liability that any
Initial Purchaser may otherwise have to the Company or any such director, officer, employee or controlling person. 
 (c) Promptly after
receipt by an indemnified party under this Section 8 of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section 8,
notify the indemnifying party in writing of the claim or the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability that it may have under this
Section 8 except to the extent it has been materially prejudiced by such failure and; provided, further, that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified
party otherwise than under this Section 8. If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to
the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party
of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 8 for any legal or other expenses subsequently incurred by the indemnified party in connection
with the defense thereof other than reasonable costs of investigation; provided, however, that the indemnified party shall have the right to employ counsel to represent jointly the indemnified party and their respective directors,
officers, employees and controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought by the indemnified party against the indemnifying party under this Section 8, if (i) the
indemnifying party and the indemnified party shall have so mutually agreed; (ii) the indemnifying party has failed within a reasonable time to retain counsel reasonably satisfactory to the indemnified party; (iii) the indemnified party and
its directors, officers, employees and controlling persons shall have reasonably concluded, based on the advice of counsel, that there may be legal defenses available to them that are different from or in addition to those available to the
indemnifying party; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the indemnified party or their respective directors, officers, employees or controlling persons, on the one hand, and the
indemnifying party, on the other hand, and representation of both sets of parties by the same counsel would present a conflict due to actual or potential differing interests between them, and in any such event the fees and expenses of such separate
counsel shall be paid by the indemnifying party. No indemnifying party shall (x) without the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld, delayed or conditioned), settle or compromise or
consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or
potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or


  
 26 












 
proceeding and 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, or (y) be liable for any settlement of
any such action effected without its written consent (which consent shall not be unreasonably withheld, delayed or conditioned), but if settled with the consent of the indemnifying party or if there be a final judgment of the plaintiff in any such
action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment. 

(d) If the indemnification provided for in this Section 8 shall for any reason be unavailable to or insufficient to hold harmless an
indemnified party under Section 8(a) or 8(b) in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified party,
contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, (i) in such proportion as shall be appropriate to reflect the relative benefits received by
the Company, on the one hand, and the Initial Purchasers, on the other, from the offering of the Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to
reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company, on the one hand, and the Initial Purchasers, on the other, with respect to the statements or omissions that resulted in such
loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by the Company, on the one hand, and the Initial Purchasers, on the other, with respect to such
offering shall be deemed to be in the same proportion as the total net proceeds from the offering of the Securities purchased under this Agreement (before deducting expenses) received by the Company, on the one hand, and the total underwriting
discounts and commissions received by the Initial Purchasers with respect to the Securities purchased under this Agreement, on the other hand, bear to the total gross proceeds from the offering of the Securities under this Agreement as set forth on
the cover page of the Offering Memorandum. The relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information
supplied by the Company, or the Initial Purchasers, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Initial Purchasers agree that it
would not be just and equitable if contributions pursuant to this Section 8(d) were to be determined by pro rata allocation (even if the Initial Purchasers were treated as one entity for such purpose) or by any other method of allocation that
does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this
Section 8(d) shall be deemed to include, for purposes of this Section 8(d), 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 Section 8(d), no Initial Purchaser shall be required to contribute any amount in excess of the amount by which the net proceeds from the sale to Eligible Purchasers of the Securities initially purchased by it exceeds the
amount of any damages that such Initial Purchaser has otherwise paid or become liable to pay by reason of any untrue or alleged untrue statement or omission or alleged omission. 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 such fraudulent misrepresentation. The Initial Purchasers’ obligations to contribute as provided in this Section 8(d) are
several in proportion to their respective purchase obligations and not joint. 

  
 27 












 (e) The Initial Purchasers severally confirm and the Company acknowledges and agrees that
the statements with respect to the offering of the Securities by the Initial Purchasers set forth in the section entitled “Stabilization, Short Positions, Market Making and Trading” appearing under the section entitled “Plan of
Distribution” in the Pricing Disclosure Package and the Offering Memorandum are correct and constitute the only information concerning such Initial Purchasers furnished in writing to the Company by or on behalf of the Initial Purchasers
specifically for inclusion in the Preliminary Offering Memorandum, the Pricing Disclosure Package and the Offering Memorandum or in any amendment or supplement thereto. 

9. Defaulting Initial Purchasers. 

(a) If, on the Closing Date or the Option Closing Date, as the case may be, any Initial Purchaser defaults in its obligations to purchase the
Securities that it has agreed to purchase under this Agreement, the remaining non-defaulting Initial Purchasers may in their discretion arrange for the purchase of such Securities by the non-defaulting Initial Purchasers or other persons satisfactory to the Company on the terms contained in this Agreement. If, within 36 hours after any such default by any Initial Purchaser, the non-defaulting Initial Purchasers do not arrange for the purchase of such Securities, then the Company shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Initial Purchasers to purchase such Securities on such terms. In the event that within the respective prescribed periods, the non-defaulting Initial Purchasers
notify the Company that they have so arranged for the purchase of such Securities, or the Company notifies the non-defaulting Initial Purchasers that it has so arranged for the purchase of such Securities,
either the non-defaulting Initial Purchasers or the Company may postpone the Closing Date or the Option Closing Date, as the case may be, for up to seven full business days in order to effect any changes that
in the opinion of counsel for the Company or counsel for the Initial Purchasers may be necessary in the Pricing Disclosure Package, the Offering Memorandum or in any other document or arrangement, and the Company agrees to promptly prepare any
amendment or supplement to the Pricing Disclosure Package or the Offering Memorandum that effects any such changes. As used in this Agreement, the term “Initial Purchaser” includes, for all purposes of this Agreement unless the context
requires otherwise, any party not listed in Schedule I hereto that, pursuant to this Section 9, purchases Securities that a defaulting Initial Purchaser agreed but failed to purchase. 

(b) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Initial Purchaser or Initial Purchasers by
the non-defaulting Initial Purchasers and the Company as provided in paragraph (a) above, the aggregate principal amount of such Securities that remains unpurchased on the Closing Date or the Option
Closing Date, as the case may be, does not exceed one-eleventh of the aggregate principal amount of all the Securities to be purchased on such date, then the Company shall have the right to require each non-defaulting Initial Purchaser to purchase the principal amount of Securities that such Initial Purchaser agreed to purchase hereunder on such date plus such Initial Purchaser’s pro rata share (based on the
principal amount of Securities that such Initial Purchaser agreed to purchase hereunder on such date) of the Securities of such defaulting Initial Purchaser or Initial Purchasers for which such arrangements have not been made; provided that
the non-defaulting Initial Purchasers shall not be obligated to purchase more than 110% of the aggregate principal amount of Securities that it agreed to purchase on the Closing Date or the Option Closing
Date, as the case may be, pursuant to the terms of Section 3. 

  
 28 












 (c) If, after giving effect to any arrangements for the purchase of the Securities of a
defaulting Initial Purchaser or Initial Purchasers by the non-defaulting Initial Purchasers and the Company as provided in paragraph (a) above, the aggregate principal amount of such Securities that
remains unpurchased on the Closing Date or the Option Closing Date, as the case may be, exceeds one-eleventh of the aggregate principal amount of all the Securities to be purchased on such date, or if the
Company shall not exercise the right described in paragraph (b) above, then this Agreement or, with respect to the Option Closing Date, the obligation of the Initial Purchasers to purchase Additional Securities on the Option Closing Date, as
the case may be, shall terminate without liability on the part of the non-defaulting Initial Purchasers. Any termination of this Agreement pursuant to this Section 9 shall be without liability on the part
of the Company, except that the Company will continue to be liable for the payment of expenses as set forth in Sections 6 and 11 and except that the provisions of Section 8 shall not terminate and shall remain in effect. 

(d) Nothing contained herein shall relieve a defaulting Initial Purchaser of any liability it may have to the Company or any non-defaulting Initial Purchaser for damages caused by its default. 
 10. Termination. The
obligations of the Initial Purchasers hereunder may be terminated by the Initial Purchasers by notice given to and received by the Company prior to delivery of and payment for the Securities if, prior to that time, any of the events described in
Sections 7(i) or 7(m) shall have occurred or if the Initial Purchasers shall decline to purchase the Securities for any reason permitted under this Agreement. 

11. Reimbursement of Initial Purchasers’ Expenses. If (a) the Company for any reason fails to tender the
Securities for delivery to the Initial Purchasers, or (b) the Initial Purchasers shall decline to purchase the Securities for any reason permitted under this Agreement, the Company shall reimburse the Initial Purchasers for all reasonable out-of-pocket expenses (including reasonable fees and disbursements of counsel for the Initial Purchasers) incurred by the Initial Purchasers in connection with this Agreement
and the proposed purchase of the Securities, and upon demand the Company shall pay the full amount thereof to the Initial Purchasers. 
 12.
Notices, etc. All statements, requests, notices and agreements hereunder shall be in writing, and:

in this Agreement shall also be deemed to be for the benefit of directors, officers and employees of the Initial Purchasers and each person or persons, if any, controlling any Initial Purchaser within the meaning of Section 15 of the Securities
Act, and (b) the indemnity agreement of the Initial Purchasers contained in Section 8(b) of this Agreement shall be deemed to be for the benefit of the directors, officers and employees of the Company and any person controlling the Company

under or in respect of this Agreement or any provision contained herein. 
 14. Survival. The respective indemnities, rights of
contribution, representations, warranties and agreements of the Company and the Initial Purchasers contained in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall survive the delivery of and payment for
the Securities and shall remain in full force and effect, regardless of any termination of this Agreement or any investigation made by or on behalf of any of them or any person controlling any of them. 

15. Definition of the Terms “Business Day”, “Affiliate” and
“Subsidiary”. For purposes of this Agreement, (a) “business day” means any day on which the New York Stock Exchange, Inc. is open for trading, and (b) “affiliate” and
“subsidiary” have the meanings set forth in Rule 405 under the Securities Act, unless otherwise indicated. 
 16. Recognition

 (a) In the event that any Initial Purchaser that is a Covered Entity becomes subject to a
proceeding under a U.S. Special Resolution Regime, the transfer from such Initial Purchaser of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under
the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States. 

(b) In the event that any Initial Purchaser that is a Covered Entity or a BHC Act Affiliate of such Initial Purchaser becomes subject to a
proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Initial Purchaser are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S.
Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.

 Initial Purchasers referred to
below 
 c/o BofA Securities, Inc. 
 One Bryant Park 

New York, New York 10036 
 c/o Jefferies LLC 

520 Madison Avenue

Ladies and Gentlemen: 
 The undersigned
understands that you and certain other firms (the “Initial Purchasers”) propose to enter into the Purchase Agreement (the “Purchase Agreement”) providing for the purchase by the Initial Purchasers of Senior
Convertible Notes due 2027 (the “Securities”) of InterDigital, Inc., a Pennsylvania corporation (the “Company”). The Securities will be convertible into cash, shares of the Company’s common stock, $0.01 par
value per share (the “Common Stock”), or a combination of cash and shares of Common Stock, at the Company’s election, and that the Initial Purchasers propose to reoffer the Securities in Exempt Resales (as such term is defined
in the Purchase Agreement) (the “Offering”). 
 In consideration of the execution of the Purchase Agreement by the Initial
Purchasers, and for other good and valuable consideration, the undersigned hereby irrevocably agrees that, without the prior written consent of BofA Securities, Inc. and Jefferies LLC, on behalf of the Initial Purchasers, the undersigned will not,
directly or indirectly, (1) offer for sale, sell, pledge, loan or otherwise transfer or dispose of (or enter into any transaction or device that is designed to, or could reasonably be expected to, result in the transfer or disposition by any
person at any time in the future of) any shares of Common Stock (including, without limitation, shares of Common Stock that may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the Securities and
Exchange Commission and shares of Common Stock that may be issued pursuant to any restricted stock unit or upon exercise of any options or warrants) or securities convertible into or exercisable or exchangeable for Common Stock, or sell or grant
options, rights or warrants with respect to any shares of Common Stock or 











 
securities convertible into or exchangeable for Common Stock, (2) enter into any swap, agreement or other derivatives transaction that transfers to another, in whole or in part, any of the
economic benefits or risks of ownership of shares of Common Stock, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or other securities, in cash or otherwise,
(3) make any demand for or exercise any right or cause to be filed a registration statement, including any amendments thereto, with respect to the registration of any shares of Common Stock or securities convertible into or exercisable
or exchangeable for Common Stock or any other securities of the Company or (4) publicly disclose the intention to do any of the foregoing, for a period commencing on the date hereof and ending on and including the 60th day after the date of the Offering Memorandum relating to the Offering (such 60-day period, the “Lock-Up
Period”); provided, however, that this Lock-Up Letter Agreement shall not apply to (i) any bona fide gift of shares of Common Stock or securities convertible into or exercisable or
exchangeable for Common Stock, provided that the donee or donees thereof agree to be bound in writing by the restrictions set forth in this Lock-Up Letter Agreement, (ii) the establishment or
amendment of a sales plan pursuant to Rule 10b5-1 under the Securities Exchange Act of 1934, as amended, provided that no sales under such plans occur during the
Lock-Up Period, (iii) trades under any Rule 10b5-1 plan that has been entered into by the undersigned prior to the date of this
Lock-Up Letter Agreement, (iv) transfers to a trust for the direct or indirect benefit of the transferor or the immediate family of the transferor, provided that such transferee agrees to be bound
in writing by the restrictions set forth in this Lock-Up Letter Agreement, (v) exercises of options to purchase Common Stock that have been granted prior to the date of this
Lock-Up Letter Agreement, (vi) the sale of shares of Common Stock to satisfy tax withholding obligations arising as a result of the exercise of outstanding options or the vesting of restricted stock units
and (vii) the settlement by the Company of fractional restricted stock units for cash upon vesting of restricted stock units. 
 In
furtherance of the foregoing, the Company and its transfer agent are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Lock-Up
Letter Agreement. 
 It is understood that, if the Company notifies the Initial Purchasers that it does not intend to proceed with the
Offering, if the Purchase Agreement does not become effective, or if the Purchase Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Securities, the
undersigned will be released from its obligations under this Lock-Up Letter Agreement. 
 The
undersigned understands that the Company and the Initial Purchasers will proceed with the Offering in reliance on this Lock-Up Letter Agreement. This Lock-Up Letter
Agreement shall be governed by and construed in accordance with the laws of the State of New York. The undersigned hereby consents and agrees that execution and delivery of this Lock-Up Letter Agreement by
electronic mail or other electronic transmission is legal, valid and binding for all purposes.

 Whether or not the Offering actually occurs depends on a number of factors, including market
conditions. Any Offering will only be made pursuant to a Purchase Agreement, the terms of which are subject to negotiation between the Company and the Initial Purchasers.

 The undersigned hereby represents and warrants that the undersigned has full power and
authority to enter into this Lock-Up Letter Agreement and that, upon request, the undersigned will execute any additional documents necessary in connection with the enforcement hereof. Any obligations of the
undersigned shall be binding upon the heirs, personal representatives, successors and assigns of the undersigned.

 EXHIBIT B-1 

FORM OF OPINION OF ISSUER’S COUNSEL 
  

	 	1.	 Based solely upon a review of the good standing certificates relating to each of the Significant Subsidiaries,
each of the Significant Subsidiaries is a validly existing corporation in good standing under the laws of the State of Delaware. 


  

	 	2.	 The Purchase Agreement has been duly executed and delivered by the Company. 



 

	 	3.	 The Securities, when executed by the Company and authenticated by the Trustee in accordance with the provisions
of the Indenture (which authentication we have not determined by inspection of the Securities) and issued and delivered to the Initial Purchasers against payment of the purchase price therefor specified in the Purchase Agreement, will constitute
valid and legally binding obligations of the Company, enforceable against the Company in accordance with their terms and will be entitled to the benefits of the Indenture. 



 

	 	4.	 The Indenture has been duly executed and delivered by the Company, assuming due authorization, execution and
delivery thereof by the Trustee and constitutes a valid and legally binding obligation of the Company, enforceable against the Company in accordance with its terms. 



 

	 	5.	 The execution and delivery by the Company of the Transaction Documents, the performance by the Company of its
obligations under the Transaction Documents and the issuance of the Securities do not violate any provisions of any U.S. federal or New York state law, rule or regulation. The execution and delivery by the Company of the Transaction Documents, the
performance by the Company of its obligations under the Transaction Documents and the issuance of the Securities do not violate, or constitute a default under, any Reviewed Agreement, and do not violate any Reviewed Judgment. 



 

	 	6.	 No consent, approval or authorization of, or designation, declaration or filing with, any U.S. federal or New
York governmental authority on the part of the Company is required for valid execution and delivery by the Company of the Transaction Documents or the issuance and sale by the Company of the Securities pursuant to the Purchase Agreement and the
Indenture and the issuance of the Conversion Shares. 


  

	 	7.	 The statements set forth in the Disclosure Package and the Final Offering Memorandum under the caption
“Description of the Notes,” insofar as such statements purport to constitute summaries of the Securities, fairly summarize in all material respects the matters referred to therein. 



  
 Exhibit B-1 













	 	8.	 The statements set forth in the Disclosure Package and the Final Offering Memorandum under the caption
“Certain U.S. Federal Income Tax Considerations,” insofar as such statements purport to summarize provisions of the United States federal tax laws referred to therein or legal conclusions with respect thereto, fairly summarize such matters
in all material respects. 


  

	 	9.	 The Company, is not and immediately after giving effect to the offering and sale of the Securities and the
application of the proceeds thereof as described in the Disclosure Package and Final Offering Memorandum, will not be required to be registered as an “investment company,” as such term is defined in the Investment Company Act.



  

	 	10.	 No registration of the Securities under the Securities Act is required for the sale of the Securities by the
Company to the Initial Purchasers pursuant to the Purchase Agreement or for the initial resale of the Securities by the Initial Purchasers in the manner contemplated by the Purchase Agreement, the Disclosure Package and the Final Offering Memorandum
and it is not necessary to qualify the Indenture under the Trust Indenture Act (it being understood that no opinion is expressed as to any subsequent resale of the Securities or the Conversion Shares, or, in either case, the consequences thereof).




  
 Exhibit B-1 












 NEGATIVE ASSURANCE 

We have participated in conferences with certain officers and other representatives of the Company, representatives of the independent
certified public accountants of the Company and your representatives and counsel at which the contents of the Pricing Disclosure Package, the Final Offering Memorandum and related matters were reviewed and discussed and, although we are not passing
upon and do not assume any responsibility for the accuracy, completeness or fairness of the Pricing Disclosure Package or the Final Offering Memorandum (except as and to the extent set forth in paragraphs (8) and (9) of our opinion letter to
you dated the date hereof), and we have made no independent check or verification thereof, no facts have come to our attention in the course of such review and discussion that have caused us to believe that: 

(a) the Pricing Disclosure Package, at the Applicable Time, included an untrue statement of a material fact or omitted to state a material fact
necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading or 
 (b)
the Final Offering Memorandum, as of its date or as of the date hereof, included or includes an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading. 
 In providing this letter to you as Initial Purchasers, we have not been called
to pass upon, and we express no view regarding, the financial statements and related schedules and the financial and statistical data derived from such financial statements or schedules included in or omitted from the Disclosure Package or Final
Offering Memorandum. 

  
 Exhibit B-1 












 EXHIBIT B-2 

FORM OF OPINION OF 

CHIEF LEGAL OFFICER AND CORPORATE SECRETARY 
  

	(i)	 To such counsel’s actual knowledge, (a) each of the Company’s issued patents were validly and
properly issued; (b) the Company has clear title to or has rights in each of the Company’s Intellectual Property Rights; (c) none of the Company’s issued patents have been revoked; and (d) the Company has properly filed and
has prosecuted in a timely and reasonable manner, or is so prosecuting, each of the Company’s pending patent applications and granted patents; except, in each case of clauses (a) through (d), where such failure has not had, and could not
reasonably be expected to have, a Material Adverse Effect or could not reasonably be expected to have a material adverse effect on the performance of the Purchase Agreement, the Indenture and the Notes or the consummation of the transactions
contemplated thereby. 


  

	(ii)	 To such counsel’s actual knowledge and except as described in each of the Preliminary Offering Memorandum
and the Offering Memorandum, there are no legal or governmental proceedings pending to which the Company or any of its subsidiaries is a party or of which any property or assets (including Intellectual Property Rights) of the Company or any of its
subsidiaries is the subject that could reasonably be expected to have a Material Adverse Effect or could reasonably be expected to prohibit the performance by the Company of the Purchase Agreement, the Indenture and the Notes or the consummation of
the transactions contemplated thereby; and, to such counsel’s actual knowledge, no such proceedings are threatened or contemplated by governmental authorities or others. 



 

	(iii)	 To such counsel’s actual knowledge, there are no contracts or other documents of a character that would be
required to be described in the Preliminary Offering Memorandum or the Offering Memorandum if the Preliminary Offering Memorandum and the Offering Memorandum were considered a prospectus included in a Registration Statement on Form S-3 that are not described therein. 



  
 Exhibit B-2 












 EXHIBIT B-3 

FORM OF OPINION OF PENNSYLVANIA COUNSEL 
  

	 	1.	 Each of the Company and InterDigital Wireless, Inc. is a corporation organized and, as of the date set forth on
the Good Standing Certificate, presently subsisting under the laws of the Commonwealth of Pennsylvania, with corporate power to conduct its business as described in the Preliminary Offering Memorandum and the Final Offering Memorandum.



  

	 	2.	 The Company has the corporate power and authority to execute, deliver and perform its obligations under the
Transaction Documents and to issue and sell the Notes. 


  

	 	3.	 The Company has an authorized capitalization as set forth in the Preliminary Offering Memorandum and the Final
Offering Memorandum. 


  

	 	4.	 Insofar as the statements in the Preliminary Offering Memorandum and Final Offering Memorandum under the
headings “Description of Capital Stock — Common Stock”, “—Preferred Stock” and “—Anti-Takeover Effects of Pennsylvania Law and Relevant Provisions of Our Articles of Incorporation and Bylaws” constitute a
summary of specific provisions of the Governing Documents or laws of the Commonwealth of Pennsylvania referred to therein, such statements present in all material respects a fair and accurate summary of such provisions of the Governing Documents or
laws of the Commonwealth of Pennsylvania. 


  

	 	5.	 The Purchase Agreement has been duly authorized, executed and delivered by the Company. 



 

	 	6.	 The Indenture has been duly authorized, executed and delivered by the Company. 



 

	 	7.	 The Notes have been duly authorized by the Company, and the Global Note has been duly executed and delivered by
the Company. 


  

	 	8.	 The shares of Common Stock initially issuable upon conversion of the Notes pursuant to the Indenture have been
duly authorized and validly reserved for issuance by all necessary corporate action of the Company, and, when issued and delivered upon conversion of the Notes in accordance with the terms of the Notes and the Indenture, will be validly issued,
fully paid and non-assessable. 


  

	 	9.	 Unless the articles of incorporation of a Pennsylvania corporation so provide, there are no preemptive rights
under the PABCL to subscribe for or purchase shares of the common stock of such corporation. There are no preemptive or similar rights to subscribe for or to purchase any shares of the Common Stock pursuant to the Governing Documents.



  

	 	10.	 The execution, delivery and performance by the Company of each of the Transaction Documents to which it is a
party and the consummation by the Company of the transactions contemplated by the Transaction Documents to which it is a party 



  
 Exhibit B-3 













	 	
(including the issuance of shares of Common Stock initially issuable upon conversion of the Notes in accordance with the Notes and the Indenture) do not result in (i) a violation or breach
of the Governing Documents or (ii) a violation of any statute, rule or regulation of the Commonwealth of Pennsylvania known to us to be applicable to the Company in a transaction of the type contemplated by the Transaction Documents.


  

	 	11.	 No consent, approval, authorization or order of, or filing or registration with, any Pennsylvania governmental
agency, court or body having jurisdiction over the Company is required to be obtained or made by the Company for the execution, delivery and performance by the Company of the Transaction Documents or for the consummation of the transactions
contemplated by each of the Transaction Documents, except (i) such as have been obtained or made prior to the date hereof; (ii) such as may be required under state securities or “blue sky” laws (as to which we express no
opinion); and (iii) as otherwise required by any federal securities laws of the United States of America, as to which we express no opinion. 



  
 Exhibit B-3
