 Ladies and Gentlemen: 

InterDigital, Inc., a Pennsylvania corporation (the “Company”), proposes, upon the terms and conditions set forth in this
agreement (this “Agreement”), to issue and sell to the Initial Purchasers (the “Initial Purchasers”) named in Schedule I attached to this Agreement for whom you are acting as representative (the
“Representative”) $350,000,000 in aggregate principal amount of its 2.00% Senior Convertible Notes due 2024 (the “Firm Securities”). The Securities will (i) have terms and provisions that are summarized in the
Offering Memorandum (as defined below) and (ii) are to be issued pursuant to an Indenture (the “Indenture”) to be entered into between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee (the
“Trustee”). The Company also proposes to issue and sell to the Initial Purchasers not more than an additional $50,000,000 of its 2.00% Senior Convertible Notes due 2024 (the “Additional Securities”) solely to cover
over-allotments if and to the extent that the Initial Purchasers shall have determined to exercise the right to purchase such 2.00% Senior Convertible Notes due 2024 granted to the Initial Purchasers in Section 3(b) hereof. The Firm Securities
and the Additional Securities are hereinafter collectively referred to as the “Securities.” The Securities will be convertible into shares of the Company’s common stock, $0.01 par value per share (the “Common
Stock”), cash or a combination of Common Stock and cash, at the Company’s election, including any such shares issuable upon conversion in connection with a “make-whole fundamental change” (as defined in the Offering
Memorandum) (the “Underlying Securities”), as set forth in the Offering Memorandum. This Agreement is to confirm the agreement concerning the purchase of the Securities from the Company by the Initial Purchasers. 

 1. Purchase and Resale of the Securities. The Securities will be offered and sold to
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
preliminary offering memorandum, dated May 29, 2019 (the “Preliminary Offering Memorandum”), a pricing term sheet substantially in the form attached hereto as Schedule II (the “Pricing Term Sheet”) setting
forth the terms of the Securities omitted from the Preliminary Offering Memorandum and certain other information and an offering memorandum, dated May 29, 2019 (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 a.m. (New York City time) on the business day immediately following the date of this Agreement. 

Any reference to the Preliminary Offering Memorandum, the Pricing Disclosure Package or the Offering Memorandum shall be deemed to
refer to and include the Company’s most recent Annual Report on Form 10-K, and all subsequent documents filed with the United States Securities and Exchange Commission (the “Commission”)

or the Offering Memorandum, as the case may be. Any reference to the Preliminary Offering Memorandum, the Pricing Disclosure Package or the Offering Memorandum, as the case may be, as amended or supplemented, as of any specified date, shall
be deemed to include any documents filed with the Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act after the date of the Preliminary Offering Memorandum, Pricing Disclosure Package or the Offering Memorandum, as the
case may be, and prior to such specified date. All documents filed under the Exchange Act and so deemed to be included in the Preliminary Offering Memorandum, Pricing Disclosure Package or the Offering Memorandum, as the case may be, or any
amendment or supplement thereto are hereinafter called the “Exchange Act Reports”. 
 You have advised the Company that you
will offer and resell (the “Exempt Resales”) the Securities purchased by you hereunder on the terms set forth in each of the Pricing Disclosure Package and the Offering Memorandum, as amended or supplemented, solely to persons whom
you reasonably believe to be “qualified institutional buyers” as defined in Rule 144A under the Securities Act (“QIBs”). Those persons specified in the immediately preceding sentence are referred to herein as

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 Representative 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 $50,000,000 aggregate principal amount of Additional Securities at the Purchase Price, plus accrued interest, if any, from the Closing Date, solely to cover over-allotments. The Representative 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, the Closing Date. 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 at least two business days after the written notice is
given and may not be earlier than the closing date for the Firm Securities nor later than ten business days after the date of such notice. On each day, 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 

  
 15 

 
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 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. 
 (e) Each of the Initial Purchasers hereby
acknowledges that upon original issuance thereof, 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 consent to such reliance.

Purchasers of and payment for the Securities shall be made at the office of Simpson Thacher & Bartlett LLP, at 10:00 A.M., New York City time, on June 3, 2019 (the “Closing Date”). The place of closing for the
Securities and the Closing Date 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

be amended or supplemented as they may reasonably request. 
 (b) The Company will prepare the Offering Memorandum in a form approved by the

(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. 

  
 17 

 (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 Representative, 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 Representative and, if requested by the
Representative, 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
Securities for offering and sale under the securities or Blue Sky laws of such jurisdictions as the Initial Purchasers 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 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.

in each case without the prior written consent of Barclays Capital Inc., on behalf of the Initial Purchasers, and to cause each officer, director and stockholder of the Company set forth on Schedule IV hereto to furnish to the Representative,
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 

  
 18 

 
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 Disclosure Package, (3) the issuance of shares upon the
exercise of warrants, options or restricted stock units or conversion of any convertible security existing on the date hereof and described in the Pricing Disclosure Package or (4) the issuance of the warrants as described 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) under the Securities Act (if any). 
 (i) The Company
will apply the net proceeds from the sale of the Securities to be sold by it hereunder substantially in accordance with the description set forth in the Pricing Disclosure Package and the Offering Memorandum under the caption “Use of

(k) The Company will use its best efforts to permit the Securities and the 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 under the Securities Act) 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

Act, or (B) transfer any Securities that have been acquired by any of them, except for (1) the transfer of Securities acquired by affiliates of the Company to the Company or one of its subsidiaries or (2) the surrender of Securities

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 

  
 19 

 
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 under, or Regulations D or S of, the Securities Act.

shall have furnished to such counsel such documents and information as such counsel reasonably requests for the purpose of enabling them to pass upon such matters. 

(g) At the time of execution of this Agreement, the Initial Purchasers shall have received from PricewaterhouseCoopers LLP a letter, in form
and substance satisfactory to the Initial Purchasers, addressed to the Initial Purchasers and dated the date hereof (the “initial letter”) (i) confirming that they are independent public accountants within the meaning of the
Securities Act and are in compliance with the applicable requirements relating to the qualification of accountants under Rule 2-01 of Regulation S-X of the Commission,
(ii) stating, as of the date hereof (or, with respect to matters involving changes or developments since the respective dates as of which specified financial information is given in the Pricing Disclosure Package, as of a date not more than
three days prior to the date hereof), the conclusions and findings of such firm with respect to the financial information and (iii) covering such other matters as are ordinarily covered by accountants’ “comfort letters” to
underwriters in connection with registered public offerings. 
 (h) With respect to the initial letter of PricewaterhouseCoopers LLP, the
Company shall have furnished to the Initial Purchasers a “bring-down letter” of such accountants, addressed to the Initial Purchasers and dated the Closing Date (i) confirming that they are independent public accountants within the
meaning of the Securities Act and are in compliance with the applicable requirements relating to the qualification of accountants under Rule 2-01 of Regulation S-X of
the Commission, (ii) stating, as of the Closing Date (or, with respect to matters involving changes or developments since the respective dates as of which specified financial information is given in each of the Pricing Disclosure Package or the
Offering Memorandum, as of a date not more than three days prior to the date of the Closing Date), the conclusions and findings of such firm with respect to the financial information and other matters covered by the initial letter and
(iii) confirming in all material respects the conclusions and findings set forth in the initial letter. 
 (i) (i) neither the Company
nor any of its subsidiaries shall have sustained, since the date of the latest audited financial statements included or incorporated by reference in the Pricing Disclosure Package and the Offering Memorandum, any loss or interference with its
business from fire, explosion, flood or other calamity, whether or not covered by insurance, or from any labor dispute or court or governmental action, order or decree, or (ii) since such date, other than as described or contemplated in the
Pricing Disclosure Package and the Offering Memorandum, there shall not have been any change in the capital stock, long-term debt or net patents of the Company or any of its subsidiaries or any change, or any development involving a prospective
change, in or affecting the condition (financial or otherwise), results of operations, stockholders’ equity, properties, management, business or prospects of the Company and its 

  
 22 

 
subsidiaries, taken as a whole, the effect of which, in any such case described in clause (i) or (ii), is, individually or in the aggregate, in the judgment of the Representative, 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 furnished to the Initial Purchasers dated as of the Closing Date
a certificate of the Chief Executive Officer and Chief Financial Officer of the Company stating that: 
 (i) The
representations, warranties and agreements of the Company in Section 2 are true and correct on and as of the Closing Date, and the Company has complied with all its agreements contained herein and satisfied all the conditions on its part to be
performed or satisfied hereunder at or prior to the Closing Date; and 
 (ii) They have examined the Pricing Disclosure
Package and the Offering Memorandum, and, in their opinion, (A) the Pricing Disclosure Package, as of the Applicable Time, and the Offering Memorandum, as of its date and as of the Closing Date, did not and do not contain any untrue statement
of a material fact and did not and do not omit to state a material fact necessary 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 forth in a supplement or amendment to the Pricing Disclosure Package and the Offering Memorandum. 

(k) The Securities shall be eligible for clearance and settlement through DTC. 

(l) The Company and the Trustee shall have executed and delivered the Indenture, and the Initial Purchasers shall have received an original
copy thereof, duly executed by the Company and the Trustee. 
 (m) Subsequent to the execution and delivery of this Agreement there shall not
have occurred any of the following: (i) trading in securities generally on the New York Stock Exchange, the NASDAQ Global Select Market or the NYSE Amex Equities or in the
over-the-counter market, or trading in any securities of the Company on any exchange or in the over-the-counter market, shall
have been suspended or materially limited or the settlement of such trading generally shall have been materially disrupted or minimum prices shall have been established on any such exchange or such market by the Commission, by such exchange or by
any other regulatory body or governmental authority having jurisdiction, (ii) a general moratorium on commercial banking activities shall have been declared by federal or state authorities, (iii) the United States shall have become engaged
in hostilities, there shall have been an escalation in hostilities involving the United States or there shall have been a declaration of a national emergency or war by the United States, (iv) there shall have occurred such a material adverse
change in general economic, political or financial conditions, including, without limitation, as a result of terrorist activities after the date hereof (or the effect of international conditions on the

  
 23 

 
financial markets in the United States shall be such), as to make it, in the judgment of the Representative, impracticable or inadvisable to proceed with the offering or delivery of the
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
rating organization”, as that term is defined under Section 3(a)(62) of the Exchange Act (“Nationally Recognized Rating Organization”) or (vi) any Nationally Recognized Rating Organization publicly announcing that it
has under surveillance or review, with possible negative implications, its rating of any of the Company’s debt securities. 
 (n) On or
prior to the Closing Date, the Company shall have furnished to the Initial Purchasers such further certificates and documents as the Initial Purchasers may reasonably request. 

(o) The Underlying Securities issuable upon conversion of the Securities shall have been duly listed, subject to notice of issuance, on the
NASDAQ Global Select Market. 
 (p) The Lock-Up Agreements between the Representative and the
officers and directors of the Company set forth on Schedule IV, delivered to the Representative on or before the date of this Agreement, shall be in full force and effect on the Closing Date and the Option Closing Date, as the case may be.

 The several obligations of the Initial Purchasers to purchase Additional Securities hereunder are subject to the delivery to the
Representative on the applicable Option Closing Date of such documents as the Representative 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, evidence and certificates
mentioned above or elsewhere in this Agreement shall be deemed in compliance with the provisions hereof only if they are in form and substance reasonably satisfactory to counsel for the Initial Purchasers. 

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 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

  
 24 

 
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 Representative
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 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 Representative 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. 

  
 25 

 (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 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. 

  
 26 

 (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. 
 (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 last paragraph on the front cover of the Offering Memorandum
and 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. 

  
 27 

 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. 
 (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

  
 28 

 
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: 

(a) if to the Initial Purchasers, shall be delivered or sent by mail or facsimile transmission to Barclays Capital Inc., 745 Seventh Avenue,
New York, New York 10019, Attention: Syndicate Registration (Fax: (646) 834-8133), with a copy, in the case of any notice pursuant to Section 8(c), to the Director of Litigation, Office of the General

this Section 13, any legal or equitable right, remedy or claim 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

16. Recognition of the U.S. Special Resolution Regimes. 

(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.

___, 2019 
 BARCLAYS
CAPITAL INC. 
 As Representative of the several 

Initial Purchasers referred to below 
 c/o Barclays Capital Inc.

 745 Seventh Avenue 
 New York, New York 10019 

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 2.00% Senior
Convertible Notes due 2024 (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 Barclays Capital Inc. 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, (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 75th day after the date of the
Offering Memorandum relating to the Offering (such 75-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. 
 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. 

[Signature page follows]

 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 A 

 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, fairly summarize such laws 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, GENERAL COUNSEL 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

	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.

 1. This Confirmation, together with the Agreement as defined below, evidence a complete and
binding agreement between Dealer and Counterparty as to the terms of the Transaction to which this Confirmation relates. This Confirmation shall be subject to an agreement (the “Agreement”) in the form of the 2002 ISDA Master

being declared” shall be deleted from clause (1) of such Section 5(a)(vi), and (c) the following language shall be added to the end thereof: “Notwithstanding the foregoing, a default under subsection (2) hereof shall

	Settlement Method:	  	For any Option, Net Share Settlement; provided that if the Relevant Settlement Method set forth below for such Option is not Net Share Settlement, then the Settlement Method for such Option shall be such Relevant Settlement
Method. Counterparty acknowledges its responsibilities under applicable securities laws, and in particular Section 9 and Section 10(b) of the Exchange Act and the rules and regulations thereunder, in respect of any election of a settlement
method with respect to the Relevant Convertible Notes.
		
	Relevant Settlement Method:	  	 In respect of any Option:

Shares

  
 5 

			
		  	 pursuant to Section 10.02(b) of the Indenture with a Specified Cash Amount less than USD 1,000 (such settlement method, “Low
Cash Combination Settlement”); or (C) in a combination of cash and Shares pursuant to Section 10.02(b) of the Indenture with a Specified Cash Amount equal to USD 1,000, then, in each case, the Relevant Settlement Method for
such Option shall be Net Share Settlement;
  
 (ii) if Counterparty has elected to
settle its conversion obligations in respect of the Relevant Convertible Note in a combination of cash and Shares pursuant to Section 10.02(b) of the Indenture with a Specified Cash Amount greater than USD 1,000, then the Relevant Settlement
Method for such Option shall be Combination Settlement; and
  
 (iii) if Counterparty
has elected to settle its conversion obligations in respect of the Relevant Convertible Note entirely in cash pursuant to Section 10.02(b) of the Indenture (such settlement method, “Settlement in Cash”), then the Relevant

	Settlement Method Election Conditions:	  	 For any Relevant Settlement Method other than Net Share Settlement with a Specified Cash Amount equal to USD 1,000, the Notice of Exercise or
Notice of Final Settlement Method for such Option, as applicable, shall be deemed to contain:
  

(i) a representation that, on the date of such Notice of Exercise or Notice of Final Settlement Method, as applicable, none of Counterparty and its officers
and directors is aware or in possession of any material non-public information with respect to Counterparty or the Shares;
  

(ii) a representation that Counterparty is electing the settlement method for the Relevant Convertible Note and such Relevant Settlement Method in good faith
and not as part of a plan or scheme to evade the prohibitions of Rule 10b-5 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”);

 
 (iii) a representation that Counterparty has not entered into or altered any hedging
transaction relating to the Shares corresponding to or offsetting the Transaction;
  

(iv) a representation that Counterparty is not electing the settlement method for the Relevant Convertible Note and such Relevant Settlement Method to create
actual or apparent trading activity in the Shares (or any security convertible into or exchangeable for the Shares) or to raise or depress or otherwise manipulate the price of the Shares (or any security convertible into or exchangeable for the
Shares) or otherwise in violation of the Exchange Act; and

	Net Share Settlement:	  	 If Net Share Settlement is applicable to any Option exercised or deemed exercised hereunder, in lieu of the obligations set forth in Sections
8.1 and 9.1 of the Equity Definitions, Dealer will deliver to Counterparty, on the relevant Settlement Date for each such Option, an aggregate number of Shares and, if any, cash in lieu of fractional shares as provided below (the “Net Share
Settlement Amount”) equal to the sum for each Trading Day during the applicable Conversion Period for each such Option of a number of Shares of each such Trading Day equal to (i) the Daily Option Value for such Trading Day,
divided by (ii) the VWAP Price on such Trading Day, divided by (iii) the number of Trading Days in the applicable Conversion Period; provided that in no event shall the Net Share Settlement Amount for any Option exceed
a number of Shares equal to the Applicable Limit for such Option divided by the Applicable Limit Price on the Settlement Date for the Option.
  

Dealer will deliver cash in lieu of any fractional Shares to be delivered with respect to any Net Share Settlement Share Amount valued at the VWAP Price for
the last Trading Day of the applicable Conversion Period.

		
	Combination Settlement:	  	 If Combination Settlement is applicable to any Option exercised or deemed exercised hereunder, in lieu of the obligations set forth in
Sections 8.1 and 9.1 of the Equity Definitions, Dealer will deliver to Counterparty, on the relevant Settlement Date for each such Option:
  

(i) cash (the “Combination Settlement Cash Amount”) equal to the sum for each Trading Day during the applicable Conversion Period for
such Option of an amount for each such Trading Day (the “Daily Combination Settlement Cash Amount”) equal to (A) the lesser of (1) the product of (x) the Applicable Percentage and (y) the Specified
Cash Amount minus USD 1,000 and (2) the Daily Option Value, divided by (B) the number of Trading Days in the applicable Conversion Period; provided that if the calculation in clause (A) above results in zero or a
negative number for any Trading Day, the Daily Combination Settlement Cash Amount for such Trading Day shall be deemed to be zero; and
  

(ii) an aggregate number of Shares (the “Combination Settlement Share Amount”) equal to the sum for each Trading Day during the
applicable Conversion Period for such Option of a number of Shares for each such Trading Day (the “Daily Combination Settlement Share Amount”) equal to (A) the Daily Option Value on such Trading Day minus the Daily
Combination Settlement Cash Amount for such Trading Day (the remainder, the “Daily Share Value”), divided by (B) the VWAP Price on such Trading Day, divided by (C) the number of Trading Days in the applicable
Conversion Period; provided that if the calculation in clause (A) above results in zero or a negative number for any Trading Day, the Daily Combination Settlement Share Amount for such Trading Day shall be deemed to be
zero.

  
 7 

			
		  	 provided, however, if the sum of (x) the Combination Settlement Cash Amount for any Option and (y) the sum for each Trading
Day during the applicable Conversion Period for such Option of the quotient of the Daily Share Value on such Trading Day divided by the number of Trading Days in such Conversion Period exceeded the Applicable Limit for such Option, the Combination
Settlement Share Amount for such Option shall be reduced by a number of Shares equal to the amount of such excess divided by the Applicable Limit Price on the Settlement Date for the Option, and if the amount of such excess is greater than such
Combination Settlement Share Amount, the Combination Settlement Cash Amount shall be reduced by such excess.
  

Dealer will deliver cash in lieu of any fractional Shares to be delivered with respect to any Combination Settlement Share Amount valued at the VWAP Price for
the last Trading Day of the applicable Conversion Period.

		
	Cash Settlement:	  	If Cash Settlement is applicable to any Option exercised or deemed exercised hereunder, in lieu of Section 8.1 of the Equity Definitions, Dealer will pay to Counterparty, on the relevant Settlement Date for each such Option, an
amount of cash (the “Cash Settlement Amount”) equal to the sum for each Trading Day during the applicable Conversion Period for such Option of (i) the Daily Option Value for such Trading Day, divided by (ii) the number of
Trading Days in the applicable Conversion Period; provided, however, that in no event shall the Cash Settlement Amount for any Option exceed the Applicable Limit for such Option.
		
	Daily Option Value:	  	For any Trading Day, an amount equal to (i) the Option Entitlement on such Trading Day, multiplied by (ii)(x) the VWAP Price on such Trading Day minus (y) the Strike Price on such Trading Day; provided
that if the calculation contained in clause (ii) above results in a negative number, the Daily Option Value for such Trading Day shall be deemed to be zero. In no event will the Daily Option Value be less than zero.
		
	Applicable Limit:	  	For any Option, an amount of cash equal to the Applicable Percentage multiplied by the excess of (i) the aggregate of (A) the amount of cash, if any, delivered to the Holder of the Relevant Convertible Note upon conversion
of such Convertible Note and (B) the number of Shares, if any, delivered to the Holder of the Relevant Convertible Note upon conversion of such Convertible Note multiplied by the Applicable Limit Price on the Settlement Date for the Option,
over (ii) USD 1,000.
		
	Applicable Limit Price:	  	On any day, the opening price as displayed under the heading “Op” on Bloomberg page IDCC: US <equity> (or any successor thereto).
		
	Trading Day:	  	A day on which (i) there is no Market Disruption Event and (ii) trading in the Shares generally occurs on the Exchange or, if the Shares are not then listed on the Exchange, on the principal other U.S. national or regional
securities exchange on which the Shares are then listed or, if the Shares are not then listed on a U.S. national or regional securities exchange, on the principal other market on which the Shares are then traded. If the Shares are not so listed or
traded, “Trading Day” means a Business Day.

  
 8

 “‘Market Disruption Event’ means, in respect of a Share, (i) a
failure by the primary U.S. national or regional securities exchange or market on which the Shares are listed or admitted for trading to open for trading during its regular trading session or (ii) the occurrence or existence prior to 1:00 p.m.
New York City time on any Scheduled Trading Day for the Shares for more than one half-hour period in the aggregate during regular trading hours of any suspension or limitation imposed on trading (by reason of movements in price exceeding limits
permitted by the relevant stock exchange or otherwise) in the Shares or in any options, contracts or futures contracts relating to the Shares.”

		
	VWAP Price:	  	On any Trading Day, the per Share volume-weighted average price as displayed on Bloomberg page (or any successor thereto) “IDCC <equity> AQR” in respect of the period from 9:30 a.m. to 4:00 p.m., New York City time,
on such Trading Day (or if such volume-weighted average price is unavailable at such time, the market value of one Share on such Trading Day, as determined by the Calculation Agent using a volume-weighted method). For the avoidance of doubt, the
VWAP Price will be determined without regard to after-hours trading or any other trading outside of the regular trading session hours.
		
	Conversion Period:	  	 For any Option and regardless of the Settlement Method applicable to such Option:

 
 (i) if the related Conversion Date occurs prior to the Free Convertibility Date, the 40
consecutive Trading Days commencing on, and including, the second Trading Day immediately following such Conversion Date; provided that if the Notice of Exercise for such Option specifies that Settlement in Shares or Low Cash Combination
Settlement applies to the Relevant Convertible Note, the Conversion Period shall be the 80 consecutive Trading Day period commencing on, and including, the second Trading Day immediately following the receipt of such Notice of Exercise;

 
 (ii) if the related Conversion Date occurs on or following the Free Convertibility Date,

if the Notice of Exercise or Notice of Final Settlement Method, as applicable, for such Option specifies that Settlement in Shares or Low Cash Combination Settlement applies to the Relevant Convertible Note, the Conversion Period shall be the 80
consecutive Trading Days commencing on, and including, the 81st Scheduled Trading Day immediately prior to the “Maturity Date”.

  
 9 

			
	Settlement Date:	  	For any Option, the second Business Day immediately following the final Trading Day of the applicable Conversion Period for such Option.
		
	Settlement Currency:	  	USD.
		
	Other Applicable Provisions:	  	To the extent Dealer is obligated to deliver Shares hereunder, the provisions of Sections 9.4 (except that “Settlement Date” shall be as defined above, unless a Settlement Disruption Event prevents delivery of such Shares
on that date), 9.1(c), 9.8, 9.9, 9.10, 9.11 and 9.12 of the Equity Definitions shall be applicable as if “Physical Settlement” applied to the Transaction.
		
	Representation and Agreement:	  	Notwithstanding anything to the contrary in Equity Definitions (including, but not limited to, Section 9.11 thereof), the parties acknowledge that (i) any Shares delivered to Counterparty shall be, upon delivery, subject
to restrictions and limitations arising from Counterparty’s status as issuer of the Shares under applicable securities laws, (ii) Dealer may deliver any Shares required to be delivered hereunder in certificated form in lieu of delivery
through the Clearance System and (iii) any Shares delivered to Counterparty may be “restricted securities” (as defined in Rule 144 under the Securities Act of 1933, as amended (the “Securities Act”)).
		
	Discretionary Adjustments:	  	In respect of any Relevant Settlement Method, if Counterparty is permitted to or required to exercise discretion under the terms of the Indenture with respect to any determination, calculation or adjustment relevant to conversion of
the Convertible Notes including, but not limited to, the volume-weighted average price of the Shares (but, for the avoidance of doubt, other than for determinations referred to under the heading “Method of Adjustment” below), Counterparty
shall consult with Dealer with respect thereto.
		
	Share Adjustments:	  	
		
	Method of Adjustment:	  	Calculation Agent Adjustment, which means that, notwithstanding Section 11.2(c) of the Equity Definitions (and, for the avoidance of doubt, in lieu of any adjustments pursuant to such section), upon the occurrence of any
Potential Adjustment Event (for the avoidance of doubt, other than an increase in the “Conversion Rate” pursuant to the Excluded Provisions), the Calculation Agent will make a corresponding adjustment to any one or more of the Strike
Price, Number of Options, the Option Entitlement and any other variable relevant to the exercise, settlement, payment or other terms of the Transaction. Counterparty agrees that it will notify Dealer prior to the effectiveness of any such adjustment
and, to the extent such adjustment requires an exercise of discretion by Counterparty under the terms of the Indenture, it shall exercise such discretion in good faith and in a commercially reasonable manner and promptly provide the Calculation
Agent with any additional information it reasonably requests about the Counterparty’s calculations and

  
 10 

			
		  	methodology for such adjustment[; provided that notwithstanding the foregoing, if any Potential Adjustment Event occurs during the Conversion Period but no adjustment was made to any Convertible Note under the Indenture
because the relevant “Holder” (as defined in the Indenture) was deemed to be a record owner of the underlying Shares on the related Conversion Date, then the Calculation Agent shall make an adjustment, as determined by it, to the terms
hereof in order to account for such Potential Adjustment Event.]
		
	Potential Adjustment Events:	  	Notwithstanding Section 11.2(e) of the Equity Definitions, a “Potential Adjustment Event” means an occurrence of any event or condition, as set forth in Sections 10.04(a), (b), (c), (d) and (e) and
Section 10.08 of the Indenture, that would result in an adjustment to the “Conversion Rate” (as defined in the Indenture) of the Convertible Notes; provided that in no event shall there be any adjustment hereunder as a result
of an adjustment to the “Conversion Rate” pursuant to the Excluded Provisions.
		
	Extraordinary Events:	  	
		
	Merger Events:	  	Notwithstanding Section 12.1(b) of the Equity Definitions, a “Merger Event” means the occurrence of any event or condition set forth in Section 10.05 of the Indenture.
		
	Notice of Merger Consideration:	  	Upon the occurrence of a Merger Event that causes the Shares to be converted into or exchanged for more than a single type of consideration (determined based in part upon the form of election of the holders of the Shares),
Counterparty shall promptly notify the Calculation Agent in writing of the types and amounts of consideration that holders of Shares have affirmatively elected to receive upon consummation of such Merger Event; provided that in no event shall
the date of such notification be later than the date on which such Merger Event is consummated.
		
	Consequences of Merger Events:	  	Notwithstanding Section 12.2 of the Equity Definitions (and, for the avoidance of doubt, in lieu of any adjustments or other consequences pursuant to such section), upon the occurrence of a Merger Event, with respect to any
adjustment made or effective under the terms of the Indenture as a result of such Merger Event pursuant to Section 10.05 of the Indenture, the Calculation Agent shall make a corresponding adjustment in respect of such adjustment under the
Indenture to any one or more of the nature of the Shares, the Strike Price, the Number of Options, the Option Entitlement and any other variable relevant to the exercise, settlement, payment or other terms of the Transaction, as applicable;
provided, however, that such adjustment shall be made without regard to any adjustment to the “Conversion Rate” (as defined in the Indenture) for the issuance of additional shares as set forth in the Excluded
Provisions.
		
	Nationalization, Insolvency or Delisting:	  	Cancellation and Payment (Calculation Agent Determination); provided that, in addition to the provisions of Section 12.6(a)(iii) of the Equity Definitions, it will also constitute a Delisting if the Exchange is located
in the United States and the Shares are not immediately re-listed, re-traded or re-quoted on any of the New York Stock Exchange,
the NASDAQ Global Select Market or the

  
 11 

			
		  	NASDAQ Global Market (or their respective successors); if the Shares are immediately re-listed, re- traded or
re-quoted on any such exchange or quotation system, such exchange or quotation system shall thereafter be deemed to be the Exchange.
		
	Additional Disruption Events:	  	
		
	Change in Law:	  	Applicable; provided that Section 12.9(a)(ii) of the Equity Definitions is hereby amended by (i) replacing the phrase “the interpretation” in the third line thereof with the phrase “, or public
announcement of, the formal or informal interpretation” and (ii) by replacing the word “Shares” where it appears in clause (X) thereof with the words “Hedge Position”; and provided further that Dealer shall
not exercise its rights under Section 12.9(b)(i) with respect to a Change in Law referred to in clause (Y) of Section 12.9(a)(ii) of the Equity Definitions except to the extent it is exercising its right to terminate or adjust
transactions as a result of a “Change in Law” event with respect to other similarly situated customers.
		
		  	The parties agree that, for the avoidance of doubt, for purposes of Section 12.9(a)(ii) of the Equity Definitions, “any applicable law or regulation” shall include the Dodd-Frank Wall Street Reform and Consumer
Protection Act of 2010, any rules and regulations promulgated thereunder and any similar law or regulation, and the consequences specified in Section 12.9(b)(i) of the Equity Definitions (as modified below) shall apply to any Change in Law
arising from any such act, rule or regulation.

 “Such inability described in phrases (A) or (B) above shall not constitute a
“Hedging Disruption” unless (x) such inability does not result from factors particular to Hedging Party (such as Hedging Party’s creditworthiness or financial position, or particular actions or transactions undertaken by the
Hedging Party unrelated to the hedging of the Transaction) and (y) such inability will result in continued performance by the Hedging Party under the Transaction being commercially unreasonable or commercially impracticable. For the avoidance
of doubt, the term “equity price risk” shall be deemed to include, but shall not be limited to, stock price and volatility risk. And, for the further avoidance of doubt, any such transactions or assets referred to in phrases (A) or
(B) above must be available on commercially reasonable pricing terms.”
  
 (ii)
Section 12.9(b)(iii) of the Equity Definitions is hereby amended by inserting in the third line thereof, after the words “to terminate the Transaction”, the words “or a portion of the Transaction affected by such Hedging
Disruption”.

	Hedging Party:	  	Dealer or an affiliate of Dealer that is involved in the hedging of the Transaction for all applicable Additional Disruption Events.
		
	Hedge Positions:	  	The definition of “Hedge Positions” in Section 13.2(b) of the Equity Definitions shall be amended by inserting the words “or an affiliate thereof” after the words “a party” in the third
line.
		
	Determining Party:	  	Dealer for all applicable Extraordinary Events.
		
	Acknowledgments:	  	
		
	Non-Reliance:	  	Applicable.

 5. Other Provisions. 

 

	 	(a)	 Method of Delivery. Whenever delivery of funds or other assets is required hereunder by or to
Counterparty, such delivery shall be effected through Agent. In addition, all notices, demands and communications of any kind relating to the Transaction between Dealer and Counterparty may be transmitted exclusively through Agent.

(i) If (A) an Amendment Event occurs, or (B) an “Event of Default” with respect to Counterparty under the terms of the
Convertible Notes as set forth in Section 6.01 of the Indenture occurs and the Convertible Notes are declared immediately due and payable under the terms of the Indenture, an Additional Termination Event shall occur in respect of which
(x) Counterparty shall be the sole Affected Party and the Transaction shall be the sole Affected Transaction and (y) Dealer shall be the party entitled to designate an Early Termination Date pursuant to Section 6(b) of the Agreement.

 “Amendment Event” means that Counterparty amends, modifies, supplements or obtains a waiver with respect to (i) any
term of the Indenture or the Convertible Notes governing the principal amount, coupon, maturity, repurchase obligation of Counterparty, redemption right of Counterparty, any term relating to conversion of the Convertible Notes (including changes to
the conversion rate, conversion settlement dates or conversion conditions), or (ii) any term that would require consent of the holders of not less than 100% of the principal amount of the Convertible Notes to amend, in each case without the
prior written consent of Dealer, such consent not to be unreasonably withheld. 
 (ii) Promptly (and in any event within five Scheduled
Trading Days) following any Repayment Event, Counterparty may notify Dealer in writing of such Repayment Event and the number of Convertible Notes subject to such Repayment Event (any such notice, a “Repayment Notice”).
Notwithstanding anything to the contrary in this Confirmation, the receipt by Dealer from Counterparty of (x) any Repayment Notice, within the applicable time period set forth in the preceding sentence, and (y) a written representation and
warranty by Counterparty that, as of the date of such Repayment Notice, Counterparty is not in possession of any material non-public information regarding Counterparty or the Shares, shall constitute an
Additional Termination Event as provided in this paragraph. Upon receipt of any such Repayment Notice and the related written representation and warranty, Dealer shall promptly designate an Exchange Business Day following receipt of such Repayment
Notice (which Exchange Business Day shall be on or as promptly as reasonably practicable after the related repurchase settlement date for the relevant Repayment Event) as an Early Termination Date with respect to the portion of this Transaction
corresponding to a number of Options (the “Repayment Options”) equal to the lesser of (A) the number of such Convertible Notes specified in such Repayment Notice [minus the number of “Repurchase Options” (as defined in the
Base Bond Hedge Transaction Confirmation), if any, that relate to such Convertible Notes] divided by the Applicable Percentage and (B) the Number of Options as of the date Dealer designates such Early Termination Date and, as of such date, the
Number of Options shall be reduced by the number of Repurchase Options. Any payment hereunder with respect to such termination shall be calculated pursuant to Section 6 of the Agreement as if (1) an Early Termination Date had been
designated in respect of a Transaction having terms identical to this Transaction and a Number of Options equal to the number of Repayment Options, (2) Counterparty were the sole Affected Party with respect to such Additional Termination Event,
(3) no adjustment to the “Conversion Rate” (as defined in the Indenture) for the Convertible Notes has occurred pursuant to any Excluded Provision, (4) the corresponding Convertible Notes remaining outstanding as if the
circumstances related to the Repayment Event had not occurred, (4) the relevant Repayment Event and any conversions, adjustments, agreements, payments, deliveries or acquisitions by or on behalf of Counterparty leading thereto had not occurred,
and (5) the terminated portion of the Transaction were the sole Affected Transaction. 

  
 16 

 “Repayment Event” means that (A) any Convertible Notes are
repurchased (whether in connection with or as a result of a change of control, howsoever defined, or for any other reason) by Counterparty or any of its subsidiaries, (B) any Convertible Notes are delivered to Counterparty or any of its
subsidiaries in exchange for delivery of any property or assets of Counterparty or any of its subsidiaries (howsoever described), (C) any principal of any of the Convertible Notes is repaid prior to the final maturity date of the Convertible Notes
(whether following acceleration of the Convertible Notes or otherwise), or (D) any Convertible Notes are exchanged by or for the benefit of the holders thereof for any other securities of Counterparty or any of its affiliates (or any other
property, or any combination thereof) pursuant to any exchange offer or similar transaction; provided that, in the case of clause (B) and clause (D), conversions of the Convertible Notes pursuant to the terms of the Indenture as in
effect on the date hereof shall not be Repayment Events. 
 (iii) The receipt by Dealer from Counterparty, within the applicable time period
set forth under “Notice of Exercise” above, of any Notice of Exercise in respect of the exercise of any Options that, according to such Notice of Exercise, relate to Convertible Notes that are Make-Whole Convertible Notes shall constitute
an Additional Termination Event as provided in this paragraph. Upon receipt of any such Notice of Exercise, Dealer shall designate an Exchange Business Day prior to the related settlement date for such Convertible Notes as an Early Termination Date
with respect to the portion of the Transaction corresponding to a number of Options (the “Make-Whole Conversion Options”) equal to the lesser of (A) the number of Make-Whole Convertible Notes specified in such Notice of
Exercise [minus the number of “Make-Whole Convertible Notes” (as defined in the Base Bond Hedge Transaction Confirmation), if any, that relate to such Convertible Notes], and (B) the Number of Options as of the date Dealer
designates such Early Termination Date and, as of such date, the Number of Options shall be reduced by the number of Make-Whole Conversion Options. Any payment hereunder with respect to such termination (the “Make-Whole Unwind
Payment”) shall be calculated pursuant to Section 6 of the Agreement as if (1) an Early Termination Date had been designated in respect of a Transaction having terms identical to the Transaction and a Number of Options equal to
the number of Make-Whole Conversion Options, (2) Counterparty were the sole Affected Party with respect to such Additional Termination Event and (3) the terminated portion of the Transaction were the sole Affected Transaction (and, for the
avoidance of doubt, in determining the amount payable pursuant to Section 6 of the Agreement, the Calculation Agent shall not take into account any adjustments to the Option Entitlement that result from corresponding adjustments to the
Conversion Rate pursuant to the Excluded Provisions); provided that the amount of cash payable in respect of such early termination by Dealer to Counterparty (determined, for the avoidance doubt, without regard to the immediately following
sentence or paragraph 5(n) below) shall not be greater than the product of (x) the Applicable Percentage and (y) the excess of (I)(1) the number of Make-Whole Conversion Options, multiplied by (2) the Conversion Rate (after taking
into account any applicable adjustments to the Conversion Rate pursuant to the Excluded Provisions), multiplied by (3) the Applicable Limit Price on the Settlement Date for the Option, over (II) the aggregate principal amount of the
related Make-Whole Convertible Notes, as determined by the Calculation Agent in good faith and in a commercially reasonable manner. Counterparty may irrevocably elect, if so designated in its Notice of Exercise to Dealer as set forth above, to
receive the Make-Whole Unwind Payment in Shares, in which case, in lieu of making such Make-Whole Unwind Payment as set forth above, Dealer shall deliver to Counterparty, within a commercially reasonable period of time after such designation as
determined by Dealer (taking into account existing liquidity conditions and Dealer’s hedging and hedge unwind activity or settlement activity in connection with such delivery) a number of Shares equal to such Make-Whole Unwind Payment divided
by a price per Share determined by the Calculation Agent in good faith and in a commercially reasonable manner. 

  
 17 

	 	(c)	 Understanding and Acknowledgment. Counterparty understands and acknowledges that notwithstanding any
other relationship between Counterparty and Dealer (and Dealer’s affiliates), in connection with the Transaction and any other over-the-counter derivative
transaction between Counterparty and Dealer or Dealer’s affiliates, Dealer or its affiliates, as the case may be, is acting as principal and is not a fiduciary or adviser to Counterparty in respect of any such transaction, including any entry
into or exercise, amendment, unwind or termination thereof. 

  

	 	(d)	 Dividends. If at any time during the period from and including the Premium Payment Date, to but
excluding the Expiration Date, (i) an ex-dividend date for a regular quarterly cash dividend occurs with respect to the Shares (an “Ex-Dividend
Date”), and that dividend is less than the Regular Dividend on a per Share basis or (ii) if no Ex-Dividend date for a regular quarterly cash dividend occurs with respect to the Shares in any
quarterly dividend period of Counterparty, then the Calculation Agent will make a corresponding adjustment to any one or more of the Strike Price, Number of Options, Option Entitlement and/or any other variable relevant to the exercise, settlement
or payment for the Transaction to preserve the fair value of the Options to Dealer after taking into account such dividend or lack thereof. “Regular Dividend” shall mean USD 0.35 per Share per quarter. Upon any adjustment to the
Dividend Threshold Amount (as defined in the Indenture) for the Convertible Notes pursuant to Section 10.04(d) or Section 10.05 of the Indenture, the Calculation Agent will make a corresponding adjustment to the Regular Dividend for the
Transaction. 

  

	 	(e)	 Repurchase Notices. Counterparty shall, on any day on which Counterparty effects any repurchase of
Shares, promptly give Dealer a written notice of such repurchase (a “Repurchase Notice”) on such day if following such repurchase, the Options Equity Percentage as determined on such day is (i) equal to or greater than 9% and
(ii) greater by 0.5% than the Options Equity Percentage included in the immediately preceding Repurchase Notice (or, in the case of the first such Repurchase Notice, greater than the Options Equity Percentage as of the Trade Date). The
“Options Equity Percentage” as of any day is the fraction, expressed as a percentage, (A) the numerator of which is the product of the Number of Options in the aggregate and the Option Entitlement [under the Transaction and any
other bond hedge transaction between the parties] and (B) the denominator of which is the number of Shares outstanding on such day. Counterparty agrees to indemnify and hold harmless Dealer and its affiliates and their respective officers,
directors, employees, affiliates, advisors, agents and controlling persons (each, an “Indemnified Person”) from and against any and all losses (including losses relating to Dealer’ hedging activities as a consequence of
becoming, or of the risk of becoming, a Section 16 “insider”, including without limitation, any forbearance from hedging activities or cessation of hedging activities and any losses in connection therewith with respect to the
Transaction), claims, damages, judgments, liabilities and expenses (including reasonable attorney’s fees), joint or several, which an Indemnified Person may become subject to, as a result of Counterparty’s failure to provide Dealer with a
Repurchase Notice on the day and in the manner specified in this paragraph, and to reimburse, within 30 days, upon written request, each of such Indemnified Persons for any reasonable legal or other expenses incurred in connection with
investigating, preparing for, providing testimony or other evidence in connection with or defending any of the foregoing. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or
asserted against the Indemnified Person in respect of the foregoing, such Indemnified Person shall promptly notify Counterparty in writing, and Counterparty, upon request of the Indemnified Person, shall retain counsel reasonably satisfactory to the
Indemnified Person to represent 

  
 18 

	 	
the Indemnified Person and any others Counterparty may designate in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding. Counterparty shall not be
liable for any settlement of any proceeding contemplated by this paragraph that is effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, Counterparty agrees to indemnify any
Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Counterparty shall not, without the prior written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding
contemplated by this paragraph that is in respect of which any Indemnified Person is or could have been a party and indemnity could have been sought hereunder by such Indemnified Person, unless such settlement includes an unconditional release of
such Indemnified Person from all liability on claims that are the subject matter of such proceeding on terms reasonably satisfactory to such Indemnified Person. If the indemnification provided for in this paragraph is unavailable to an Indemnified
Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then Counterparty hereunder, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such
Indemnified Person as a result of such losses, claims, damages or liabilities. The remedies provided for in this paragraph (c) are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified
Person at law or in equity. The indemnity and contribution agreements contained in this paragraph shall remain operative and in full force and effect regardless of the termination of the Transaction. 

 

	 	(f)	 Rule 10b-18. 

 

	 	(i)	 Except as disclosed to Dealer in writing prior to the date on which the offering of the Convertible Notes was
first announced, Counterparty represents and warrants to Dealer that it has not made any purchases of blocks by or for itself or any of its Affiliated Purchasers pursuant to the one block purchase per week exception in Rule 10b-18(b)(4) under the Exchange Act during each of the four calendar weeks preceding such date and the calendar week in which such date occurs (“Rule 10b-18
purchase,” “blocks” and “Affiliated Purchaser” each as defined in Rule 10b-18 under the Exchange Act). Counterparty agrees and acknowledges that it shall not, and
shall cause its affiliates and Affiliated Purchasers not to, directly or indirectly (including by means of a derivative instrument) enter into any transaction to purchase any Shares during the period beginning on such date and ending on the day on
which Dealer has informed Counterparty in writing that it has completed all purchases of Shares to hedge initially its exposure to the Transaction; provided that the foregoing shall not apply to the Counterparty’s repurchase of shares of common
stock concurrently with the offering of Convertible Notes. 

  

	 	(ii)	 On any day during any Conversion Period, neither Counterparty nor any “affiliate” or “affiliated
purchaser” (each as defined in Rule 10b-18 of the Exchange Act (“Rule 10b-18”)) shall directly or indirectly (including, without limitation, by
means of any cash-settled or other derivative instrument) purchase, offer to purchase, place any bid or limit order that would effect a purchase of, or commence any tender offer relating to, any Shares (or an equivalent interest, including a unit of
beneficial interest in a trust or limited partnership or a depository share) or any security convertible into or exchangeable or exercisable for Shares, except through Dealer or with Dealer’s prior written consent. 

  
 19 

	 	(iii)	 Counterparty agrees that it (A) will not, on any day during any Conversion Period, make, or permit to be
made (to the extent within Counterparty’s reasonable control), any public announcement (as defined in Rule 165(f) under the Securities Act) of any Merger Transaction or potential Merger Transaction unless such public announcement is made prior
to the opening or after the close of the regular trading session on the Exchange for the Shares; (B) shall promptly (but in any event prior to the next opening of the regular trading session on the Exchange) notify Dealer following any such
announcement that such announcement has been made; and (C) shall promptly (but in any event prior to the next opening of the regular trading session on the Exchange) provide Dealer with written notice specifying (i) Counterparty’s
average daily Rule 10b-18 Purchases (as defined in Rule 10b-18) during the three full calendar months immediately preceding the announcement date that were not effected
through Dealer or its affiliates and (ii) the number of Shares purchased pursuant to the proviso in Rule 10b-18(b)(4) under the Exchange Act for the three full calendar months preceding the announcement
date. Such written notice shall be deemed to be a certification by Counterparty to Dealer that such information is true and correct. In addition, Counterparty shall promptly notify Dealer of the earlier to occur of the completion of such transaction
and the completion of the vote by target shareholders. “Merger Transaction” means any merger, acquisition or similar transaction involving a recapitalization as contemplated by Rule
10b-18(a)(13)(iv) under the Exchange Act. 

  

	 	(g)	 Regulation M. Counterparty represents and warrants to Dealer that (x) Counterparty (A) was not on
the date on which the offering of the Convertible Notes was first announced, has not since such date, and is not on the date hereof, engaged in a “distribution”, as such term is used in Regulation M under the Exchange Act
(“Regulation M”), of any securities of Counterparty, other than the distribution of the Convertible Notes and (B) shall not engage in any “distribution,” as such term is defined in Regulation M, of any securities of
Counterparty other than a distribution meeting the requirements of the exceptions set forth in sections 101(b)(10) and 102(b)(7) of Regulation M, until the second Exchange Business Day immediately following the Trade Date, and (y) Counterparty
shall notify Dealer in writing of the start of a “restricted period”, as defined in Regulation M, no later than the Scheduled Trading Day immediately before the start of any such restricted period, to the extent Counterparty is engaged in
any “distribution,” as such term is defined in Regulation M, of any securities of Counterparty other than a distribution meeting the requirements of the exceptions set forth in sections 101(b)(10) and 102(b)(7) of Regulation M, on any day
during any Conversion Period. 

  

	 	(h)	 Early Unwind. In the event the sale of Convertible Notes is not consummated with the initial purchaser
for any reason by the close of business in New York on June 3, 2019 (or such later date as agreed upon by the parties) (June 3, 2019 or such later date as agreed upon being the “Early Unwind Date”), the Transaction shall
automatically terminate (the “Early Unwind”), on the Early Unwind Date and (i) the Transaction and all of the respective rights and obligations of Dealer and Counterparty under the Transaction shall be cancelled and terminated
and (ii) each party shall be released and discharged by the other party from and agrees not to make any claim against the other party with respect to any obligations or liabilities of the other party arising out of and to be performed in
connection with the Transaction either prior to or after the Early Unwind Date; provided that, except to the extent that the Early Unwind Date occurred as a result of a breach of the Purchase Agreement by Dealer or any of its affiliates,
Counterparty shall reimburse Dealer for any costs or expenses (including market losses, unless Counterparty agrees to purchase any such Shares at the cost at which Dealer purchased such Shares) relating to the unwinding of its hedging activities in
connection with the Transaction (including any loss or cost incurred as a result of its terminating, liquidating, obtaining or reestablishing any hedge or related trading position). The amount of any such reimbursement shall be determined by Dealer
in its sole good faith discretion. Dealer shall notify Counterparty of such amount and Counterparty shall pay such amount in immediately available funds on the Early Unwind Date. Dealer and Counterparty represent and acknowledge to the other that,
subject to the proviso included in this paragraph, upon an Early Unwind, all obligations with respect to the Transaction shall be deemed fully and finally discharged. 

  
 20 

	 	(i)	 Transfer or Assignment.  

 

	 	(i)	 Counterparty shall have the right to transfer or assign its rights and obligations hereunder with respect to
all, but not less than all, of the Options hereunder (such Options, the “Transfer Options”); provided that such transfer or assignment shall be subject to reasonable conditions that Dealer may impose, including but not
limited, to the following conditions: 

  

	 	(A)	 With respect to any Transfer Options, Counterparty shall not be released from its notice and indemnification
obligations pursuant to paragraph 5(e) of this Confirmation, its registration obligations pursuant to paragraph 5(p) of this Confirmation, or its obligation to provide a Notice of Merger Consideration pursuant to paragraph 2 of this Confirmation;

  

	 	(B)	 Any Transfer Options shall only be transferred or assigned to a third party that is a United States person (as
defined in the Code); 

  

	 	(C)	 Such transfer or assignment shall be effected on terms, including any reasonable undertakings by such third
party (including, but not limited to, an undertaking with respect to compliance with applicable securities laws in a manner that, in the reasonable judgment of Dealer, will not expose Dealer to material risks under applicable securities laws) and
execution of any documentation and delivery of legal opinions with respect to securities laws and other matters by such third party and Counterparty, as are requested and reasonably satisfactory to Dealer; 

 

	 	(D)	 Dealer will not, as a result of such transfer and assignment, be required to pay the transferee on any payment
date an amount under Section 2(d)(i)(4) of the Agreement greater than an amount that Dealer would have been required to pay to Counterparty in the absence of such transfer and assignment except to the extent that the greater amount is due to a
Change in Tax Law after the date of such transfer or assignment; 

  

	 	(E)	 An Event of Default, Potential Event of Default or Termination Event will not occur as a result of such
transfer and assignment; 

  

	 	(F)	 Without limiting the generality of clause (B), Counterparty shall cause the transferee to make such Payee Tax
Representations and to provide such tax documentation as may be reasonably requested by Dealer to permit Dealer to determine that results described in clauses (D) and (E) will not occur upon or after such transfer and assignment; and

  

	 	(G)	 Counterparty shall be responsible for all commercially reasonable costs and expenses, including commercially
reasonable counsel fees, incurred by Dealer in connection with such transfer or assignment. 

  

	 	(ii)	 Notwithstanding any provision of the Agreement to the contrary, Dealer may, subject to applicable law, freely
transfer and assign all of its rights and obligations under the Transaction or the Agreement without the consent of Counterparty, (x) to any of its affiliates and (y) solely to the extent required to

  
 21 

	 	
eliminate an Excess Ownership Position as provided in the immediately succeeding sentence, to any affiliate and/or any other recognized dealer in transactions such as the Transaction, where in
the case of both clauses (x) and (y), the assignee shall have a rating (or whose guarantor shall have a rating) for its long term, unsecured and unsubordinated indebtedness of A- or better by
Standard & Poor’s Ratings Services or its successor (“S&P”), or A3 or better by Moody’s Investors Service, Inc. or its successor (“Moody’s”) or, if either S&P or Moody’s ceases
to rate such debt, at least an equivalent rating or better by a substitute rating agency mutually agreed by Counterparty and Dealer; provided that either (1) the transferee in any such Transfer is a “dealer in securities”
within the meaning of Section 475(c)(1) of the Code or (2) the Transfer does not result in a deemed exchange by Counterparty within the meaning of Section 1001 of the Code provided further that Counterparty will not, as a
result of such transfer and/or assignment, be required under the Agreement or this Confirmation to (i) pay to the transferee or assignee an amount greater than the amount that it would have been required to pay to Dealer in the absence of such
transfer or assignment or (ii) receive from the transferee or assignee an amount less than the amount that Counterparty would have received from Dealer in the absence of such transfer or assignment, in each case based on the circumstances in
effect on the date of such transfer. Dealer shall provide Counterparty with written notice of any assignment. 

 If at any
time at which (1) the Equity Percentage exceeds 9.0% or (2) Dealer, Dealer Group (as defined below) or any person whose ownership position would be aggregated with that of Dealer or Dealer Group (Dealer, Dealer Group or any such person, a
“Dealer Person”) under any relevant state corporate law or state or federal bank holding company or banking laws, or other federal, state or local laws, regulations, regulatory orders or organizational documents or contracts of
Counterparty that are applicable to ownership of Shares (“Applicable Laws”), owns, beneficially owns, constructively owns, controls, holds the power to vote or otherwise meets a relevant definition of ownership in excess of a number
of Shares equal to (x) the number of Shares that would give rise to reporting or registration obligations or other requirements (including obtaining prior approval by a state or federal regulator) of a Dealer Person or could result in an
adverse effect on a Dealer Person, as determined by Dealer in its reasonable discretion, under Applicable Laws and with respect to which such requirements have not been met or the relevant approval has not been received minus (y) 1.0% of the
number of Shares outstanding on the date of determination (either such condition described in clause (1) or (2), an “Excess Ownership Position”) and Dealer is unable, after commercially reasonable efforts, to effect a transfer
or assignment on pricing terms and within a time period reasonably acceptable to it of all or a portion of the Transaction pursuant to the preceding sentence such that an Excess Ownership Position no longer exists, Dealer may designate any Scheduled
Trading Day as an Early Termination Date with respect to a portion (the “Terminated Portion”) of the Transaction, such that an Excess Ownership Position no longer exists. In the event that Dealer so designates an Early Termination
Date with respect to a portion of the Transaction, a payment shall be made pursuant to Section 6 of the Agreement as if (x) an Early Termination Date had been designated in respect of a Transaction having terms identical to the Transaction
and a Number of Options equal to the Terminated Portion, (y) Counterparty shall be the sole Affected Party with respect to such partial termination and (z) such Transaction shall be the only Terminated Transaction (and, for the avoidance
of doubt, the provisions of paragraph 5(n) shall apply to any amount that is payable by Dealer to Counterparty pursuant to this sentence). The “Equity Percentage” as of any day is the fraction, expressed as a percentage,
(A) the numerator of which is the number of Shares that Dealer and any of its affiliates subject to aggregation with Dealer, for purposes of the “beneficial ownership” test under Section 13 of the Exchange Act, and all persons
who may form a “group” (within the meaning of Rule 13d-5(b)(1) under the Exchange Act) with Dealer (“Dealer Group”), beneficially 

  
 22 

 
own (within the meaning of Section 13 of the Exchange Act) on such day and (B) the denominator of which is the number of Shares outstanding on such day. Notwithstanding any other
provision in this Confirmation to the contrary requiring or allowing Dealer to purchase, sell, receive or deliver any Shares or other securities to or from Counterparty, Dealer may designate any of its affiliates to purchase, sell, receive or
deliver such Shares or other securities and otherwise to perform Dealer’ obligations in respect of the Transaction and any such designee may assume such obligations. Dealer shall be discharged of its obligations to Counterparty to the extent of
any such performance. 
  

	 	(j)	 Staggered Settlement. Dealer may, by notice to Counterparty on or prior to any Settlement Date (a
“Nominal Settlement Date”), elect to deliver the Shares deliverable on such Nominal Settlement Date on two or more dates (each, a “Staggered Settlement Date”) or at two or more times on the Nominal Settlement Date
as follows: (i) in such notice, Dealer will specify to Counterparty the related Staggered Settlement Dates (each of which will be on or prior to such Nominal Settlement Date, but not prior to the beginning of the related Conversion Period or
delivery times and how it will allocate the Shares it is required to deliver under “Net Share Settlement” above among the Staggered Settlement Dates or delivery times; and (ii) the aggregate number of Shares that Dealer will deliver
to Counterparty hereunder on all such Staggered Settlement Dates and delivery times will equal the number of Shares that Dealer would otherwise be required to deliver on such Nominal Settlement Date. 

 

	 	(k)	 [Role of Agent. Each of Dealer and Counterparty acknowledges to and agrees with the other party hereto
and to and with the Agent that (i) the Agent is acting as agent for Dealer under the Transaction pursuant to instructions from such party, (ii) the Agent is not a principal or party to the Transaction, and may transfer its rights and
obligations with respect to the Transaction, (iii) the Agent shall have no responsibility, obligation or liability, by way of issuance, guaranty, endorsement or otherwise in any manner with respect to the performance of either party under the
Transaction, (iv) Dealer and the Agent have not given, and Counterparty is not relying (for purposes of making any investment decision or otherwise) upon, any statements, opinions or representations (whether written or oral) of Dealer or the
Agent, other than the representations expressly set forth in this Confirmation or the Agreement, and (v) each party agrees to proceed solely against the other party, and not the Agent, to collect or recover any money or securities owed to it in
connection with the Transaction. Each party hereto acknowledges and agrees that the Agent is an intended third party beneficiary hereunder. Counterparty acknowledges that the Agent is an affiliate of Dealer. Dealer will be acting for its own account
in respect of this Confirmation and the Transaction contemplated hereunder.]5 

  

	 	(l)	 Regulatory Provisions. The time of dealing for the Transaction will be confirmed by Dealer upon written
request by Counterparty. The Agent will furnish to Counterparty upon written request a statement as to the source and amount of any remuneration received or to be received by the Agent in connection with the Transaction. 

 

	 	(m)	 No Setoff. Obligations under the Transaction shall not be netted, recouped or set off (including
pursuant to Section 6 of the Agreement) against any other obligations of the parties, whether arising under the Agreement, this Confirmation, under any other agreement between the parties hereto, by operation of law or otherwise, and no other
obligations of the parties shall be netted, recouped or set off (including pursuant to Section 6 of the Agreement) against obligations under the Transaction, whether arising under the Agreement, this Confirmation, under any other agreement
between the parties hereto, by operation of law or otherwise, and each party hereby waives any such right of setoff, netting or recoupment, provided that both parties agree that subparagraph (ii) of Section 2(c) of the Agreement
shall apply to the Transaction. 

  

	5 	 Dealer to provide own Agent language as necessary.

  
 23 

	 	(n)	 Alternative Calculations and Dealer Payment on Early Termination and on Certain Extraordinary Events. If
Dealer owes Counterparty any amount in connection with the Transaction (i) pursuant to Sections 12.2, 12.3 (and “Consequences of Merger Events” above), 12.6, 12.7 or 12.9 of the Equity Definitions or (ii) pursuant to
Section 6(d)(ii) of the Agreement (a “Payment Obligation”), Dealer shall satisfy any such Payment Obligation by delivery of Termination Delivery Units (as defined below) unless Counterparty elects for Dealer to satisfy such
Payment Obligation by delivery of cash by giving irrevocable telephonic notice to Dealer, confirmed in writing within one Scheduled Trading Day, no later than noon New York time on the Early Termination Date or other date the Transaction is
cancelled or terminated, as applicable, where such notice shall include a representation and warranty from Counterparty that it is not, as of the date of the telephonic notice and the date of such written notice, aware of any material non-public information concerning itself or the Shares (where “material” shall have the meaning set forth in paragraph 5(t) below); provided that Dealer shall have the right, in its sole discretion
and notwithstanding any election by Counterparty to the contrary, to elect to satisfy any such Payment Obligation (x) by delivery of Termination Delivery Units in any event or (y) by delivery of cash in the event of (i) an Insolvency,
a Nationalization or a Merger Event, in each case, in which the consideration or proceeds to be paid to holders of Shares consists solely of cash or (ii) an Event of Default in which Counterparty is the Defaulting Party or a Termination Event
in which Counterparty is the Affected Party, which Event of Default or Termination Event resulted from an event or events within Counterparty’s control. Where Dealer is required to deliver Termination Delivery Units, Dealer shall deliver to
Counterparty a number of Termination Delivery Units having a fair market value (net of any brokerage and underwriting commissions and fees, including any customary private placement fees) equal to the amount of such Payment Obligation (such number
of Termination Delivery Units to be delivered to be determined by the Calculation Agent as the number of whole Termination Delivery Units that could be purchased over a commercially reasonable period of time with the cash equivalent of such Payment
Obligation). If the provisions set forth in this paragraph are applicable, the provisions of Sections 9.8, 9.9, 9.10, 9.11 (modified as described above) and 9.12 of the Equity Definitions shall be applicable, except that all references to
“Shares” shall be read as references to “Termination Delivery Units.” “Termination Delivery Units” means in the case of a Termination Event, Event of Default, Additional Disruption Event or Delisting, one Share
or, in the case of Nationalization, Insolvency or Merger Event, a unit consisting of the number or amount of each type of property received by a holder of one Share (without consideration of any requirement to pay cash or other consideration in lieu
of fractional amounts of any securities) in such Nationalization, Insolvency or Merger Event; provided that if such Nationalization, Insolvency or Merger Event involves a choice of consideration to be received by holders, such holder shall be
deemed to have elected to receive the maximum possible amount of cash. 

  

	 	(o)	 No Collateral. Notwithstanding any provision of this Confirmation, the Agreement, Equity Definitions, or
any other agreement between the parties to the contrary, the obligations of Counterparty under the Transaction are not secured by any collateral. 

  

	 	(p)	 Registration. Counterparty hereby agrees that if, in the good faith reasonable judgment of Dealer, the
Shares (“Hedge Shares”) acquired by Dealer for the purpose of hedging its obligations pursuant to the Transaction cannot be sold in the public market by Dealer without registration under the Securities Act, Counterparty shall, at
its election, either (i) in order to allow Dealer to sell the Hedge Shares in a registered offering, make available to Dealer an effective registration statement under the Securities Act and (A) enter into an agreement, in form and
substance reasonably satisfactory to Dealer, substantially in the 

  
 24 

	 	
form of an underwriting agreement for a registered offering, (B) provide accountant’s “comfort” letters customary in form for registered offerings of equity securities,
(C) provide disclosure opinions of nationally recognized outside counsel to Counterparty reasonably acceptable to Dealer, (D) provide other customary opinions, certificates and closing documents customary in form for registered offerings
of equity securities and (E) afford Dealer a reasonable opportunity to conduct a due diligence investigation with respect to Counterparty customary in scope for underwritten offerings of equity securities; provided, however, that
if Dealer, in its sole reasonable discretion, is not satisfied with access to due diligence materials, the results of its due diligence investigation, or the procedures and documentation for the registered offering referred to above, then clause
(ii) or clause (iii) of this paragraph shall apply at the election of Counterparty, (ii) in order to allow Dealer to sell the Hedge Shares in a private placement, enter into and comply with a private placement agreement substantially
similar to private placement purchase agreements customary for private placements of equity securities, in form and substance satisfactory to Dealer (in which case, the Calculation Agent shall make any adjustments to the terms of the Transaction
that are necessary, in its reasonable judgment, to compensate Dealer for any discount from the public market price of the Shares incurred on the sale of Hedge Shares in a private placement), or (iii) purchase the Hedge Shares from Dealer at the
closing price on such Exchange Business Days, and in the amounts, requested by Dealer. 

  

	 	(q)	 Tax Disclosure. Notwithstanding anything to the contrary herein, in the Equity Definitions or in the
Agreement, and notwithstanding any express or implied claims of exclusivity or proprietary rights, the parties (and each of their employees, representatives or other agents) are authorized to disclose to any and all persons, beginning immediately
upon commencement of their discussions and without limitation of any kind, the tax treatment and tax structure of the Transaction, and all materials of any kind (including opinions or other tax analyses) that are provided by either party to the
other relating to such tax treatment and tax structure. 

  

	 	(r)	 Status of Claims in Bankruptcy. Dealer acknowledges and agrees that this Confirmation is not intended to

discretion based on the advice of counsel to Dealer, that such postponement or extension is reasonably necessary or appropriate to preserve Dealer’s or its affiliate’s hedging or hedge unwind activity hereunder in light of existing
liquidity conditions or to enable Dealer or its affiliate to effect purchases of Shares in connection with its hedging, hedge unwind or settlement activity hereunder in a manner that would, if Dealer or such affiliate were Issuer or an affiliated
purchaser of Issuer, be in compliance with applicable legal, regulatory or self-regulatory requirements, or with related policies and procedures applicable to Dealer and/or such affiliate, provided that such requirements, policies and procedures are
generally applicable in similar situations and applied to the Transaction in a non-discriminatory manner; provided that in no event shall Dealer have the right to so postpone or add any Trading Day(s) or any
such other date beyond the 100th Trading Day immediately following the last Trading Day of the relevant Conversion Period.
