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”) pursuant to Section 13(a), 13(c), 14 or 15(d) of the United States Securities Exchange Act of 1934, as amended (the “Exchange Act”), on or prior to the date of the Preliminary Offering Memorandum, the Pricing Disclosure Package 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”).

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

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

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.

(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.

(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.

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

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., ▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇, Attention: Syndicate Registration (Fax: (▇▇▇) ▇▇▇-▇▇▇▇), with a copy, in the case of any notice pursuant to Section 8(c), to the Director of Litigation, Office of the General Counsel, Barclays Capital Inc., ▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇; and

This Agreement and the terms and provisions hereof are for the sole benefit of only those persons, except that (a) the representations, warranties, indemnities and agreements of the Company contained in this Agreement shall also be deemed to be for the benefit of directors, officers and employees of the Initial Purchasers and each person or persons, if any, controlling any Initial Purchaser within the meaning of Section 15 of the Securities Act, and (b) the indemnity agreement of the Initial Purchasers contained in Section 8(b) of this Agreement shall be deemed to be for the benefit of the directors, officers and employees of the Company and any person controlling the Company within the meaning of Section 15 of the Securities Act. Nothing in this Agreement is intended or shall be construed to give any person, other than the persons referred to in 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 termination of this Agreement or any investigation made by or on behalf of any of them or any person controlling any of them.

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

16. Recognition 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.

(c) For purposes of this Section 16, a “BHC Act Affiliate” has the meaning assigned to the term “affiliate” in, and shall be interpreted in accordance with, 12 U.S.C. § 1841(k). “Covered Entity” means any of the following: (i) a “covered entity” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 252.82(b); (ii) a “covered bank” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 47.3(b); or (iii) a “covered FSI” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 382.2(b). “Default Right” has the meaning assigned to that term in, and shall be interpreted in accordance with, 12 C.F.R. §§ 252.81, 47.2 or 382.1, as applicable. “U.S. Special Resolution Regime” means each of (i) the Federal Deposit Insurance Act and the regulations promulgated thereunder and (ii) Title II of the ▇▇▇▇-▇▇▇▇▇ ▇▇▇▇ Street Reform and Consumer Protection Act and the regulations promulgated thereunder.

LOCK-UP LETTER AGREEMENT

___, 2019

BARCLAYS CAPITAL INC.

As Representative of the several

Initial Purchasers referred to below

c/o Barclays Capital Inc.

▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇▇

▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇

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.


Very truly yours,

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.

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.

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.

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

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.

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.

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

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

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

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

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.

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.

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.
