The Company also proposes to issue and sell to the Initial Purchasers, not more than an additional $22,500,000 of its 1.375% Convertible Senior Notes due 2023 (the “Additional Notes”) if and to the extent that the Initial Purchasers shall have determined to exercise the right to purchase such 1.375% Convertible Senior Notes due 2023 granted to the Initial Purchasers in Section 3(b) hereof. The Firm Notes and the Additional Notes are hereinafter collectively referred to as the “Notes.” The Notes will

(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

such 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 Notes), 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 in any (A) Issuer Written Communication, the Preliminary Offering Memorandum, the Pricing Disclosure Package or the Offering Memorandum or in any amendment or supplement thereto, or (B) the road show presentations made to investors by the Company (whether in person or electronically) set forth on Schedule III (the “Road Show”) or (ii) the omission or alleged omission to state in any Issuer Written Communication, the Preliminary Offering Memorandum, the Pricing Disclosure Package or the Offering Memorandum, or in any amendment or supplement thereto, 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, , in reliance upon and in conformity with written information concerning such Initial Purchaser furnished to the Company through the Representatives by or on behalf of the Initial Purchasers 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 in any Issuer Written Communication, Preliminary Offering Memorandum, the Pricing Disclosure Package or the Offering Memorandum or in any amendment or supplement thereto, or (ii) the omission or alleged omission to state in any Issuer Written Communication, Preliminary Offering Memorandum, the Pricing Disclosure Package or the Offering Memorandum, or in any amendment or supplement thereto, or any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, but in each case only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with

written information concerning such Initial Purchaser furnished to the Company through the Representatives by or on behalf of that Initial Purchaser specifically for inclusion therein, which information is limited to the information set forth in Section 8(e). The foregoing indemnity agreement is in addition to any liability that any Initial Purchaser may otherwise have to the Company or any such director, officer, employee or controlling person.

(c)    Promptly after receipt by an indemnified party under this Section 8 of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the claim or the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability that it may have under paragraphs (a) or (b) above except to the extent it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure and; provided, further, that the failure to notify the indemnifying party shall not relieve the indemnifying party from any liability that it may have to an indemnified party otherwise than under paragraphs (a) or (b) above. 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 those other indemnified parties 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 under this Section 8, if (i) the indemnified party and the indemnifying 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 that there may be legal defenses available to them that are different from or in addition to those available to the indemnified party; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the indemnified parties 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 be inappropriate 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), 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), 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. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by Section 8(a) or (b) hereof, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request or disputed in good faith the indemnified party’s entitlement to such reimbursement prior to the date of such settlement.

(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 Notes, 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 hand, with respect to such offering shall be deemed to be in the same proportion as the total net proceeds from the offering of the Notes purchased under this Agreement (before deducting expenses) received by the Company, on the one hand, and the total discounts and commissions received by the Initial Purchasers with respect to the Notes purchased under this Agreement, on the other hand, bear to the total gross proceeds from the offering of the Notes 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 total underwriting discounts and commissions received by such Initial Purchaser with respect to the offering of the Notes exceeds the amount of any damages that such Initial Purchaser has

otherwise been required to pay by reason of such 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 confirms and the Company acknowledges and agrees that the statements with respect to the offering of the Notes by the Initial Purchasers set forth in the tenth and eleventh paragraph of 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 or in.

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 Notes 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 Notes 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 Notes, 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 Notes 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 Notes, or the Company notifies the non-defaulting Initial Purchasers that it has so arranged for the purchase of such Notes, 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 Notes that a defaulting Initial Purchaser agreed but failed to purchase.

(b)    If, after giving effect to any arrangements for the purchase of the Notes 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 Notes 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 Notes 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 Notes 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 Notes that such Initial Purchaser agreed to purchase hereunder on such date) of the Notes 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 Notes 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 Notes 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 Notes 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 Notes 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 Notes 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 Notes if, prior to that time, any of the events described in Sections 7(g), (i) or (l) shall have occurred or if the Initial Purchasers shall decline to purchase the Notes for any reason permitted under this Agreement.

11.    Reimbursement of Initial Purchasers’ Expenses. If (a) the Company for any reason fails to tender the Notes for delivery to the Initial Purchasers, or (b) the Initial Purchasers decline to purchase the Notes for any reason permitted under this Agreement, the Company shall reimburse the Initial Purchasers for all reasonable out-of-pocket expenses (including 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 Notes, 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:

Exhibit A

Company Counsel Opinion

1. The Company is a corporation duly incorporated and validly existing under the laws of the State of Delaware and is in good standing under such laws. The Company has requisite corporate power to own or lease its properties and carry on its business, as described in the Final Offering Memorandum. The Company is qualified to do business as a foreign corporation in the State of California.

2. The execution and delivery of the Operative Documents have been duly authorized by all necessary corporate action on the part of the Company, and the Purchase Agreement has been duly executed and delivered by the Company.

3. The Company has the corporate power to execute and deliver the Operative Documents and to perform its obligations under the terms of the Operative Documents.

4. The Securities have been duly authorized and executed by the Company and when authenticated by the Trustee in accordance with the terms 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, the Securities will constitute valid and binding obligations of the Company, enforceable against the Company in accordance with their terms.

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

6. The shares of Common Stock initially issuable upon conversion of the Securities (assuming the full physical settlement of the Securities and including shares of Common Stock issuable with respect to any Make-Whole Fundamental Change (as defined in the Indenture)) (the “Shares”) have been duly authorized by the Company and the Shares, if any, when issued upon due conversion of the Securities in accordance with the terms of the Securities and the Indenture would, if issued today, be validly issued, fully paid and nonassessable and free of preemptive rights arising under the Certificate of Incorporation, the Bylaws or the DGCL.

7. The statements set forth in the General Disclosure Package and the Final Offering Memorandum under the caption “Description of Notes” insofar as such statements purport to constitute a summary of the terms of the Indenture and the Securities, fairly summarize such terms in all material respects.

8. The statements set forth in the General Disclosure Package and the Final Offering Memorandum under the caption “Certain United States Federal Income Tax Considerations,” insofar as they purport to summarize the United States federal tax laws referred to therein or legal conclusions with respect thereto, are fair summaries in all material respects.

9. The statements set forth in the General Disclosure Package and Final Offering Memorandum under the caption “Description of Capital Stock,” insofar as such statements constitute summaries of legal matters or documents, fairly summarize the matters and documents referred to therein in all material respects.

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

11. None of the issuance and sale of the Securities being delivered on the date hereof, the execution, delivery and performance by the Company of its obligations under the Purchase Agreement, the Indenture and the Securities or the consummation of the transactions contemplated thereby will (i) violate the Certificate of Incorporation or the Bylaws, (ii) conflict with, result in a breach or violation by the Company of any of the terms or provisions of, or constitute a default by the Company under any Reviewed Agreement, (iii) result in a violation of any U.S. federal, California or New York state law, rule or regulation or the DGCL, or (iv) result in a violation of any Reviewed Judgment.

12. No consent, approval, authorization, order, registration or qualification of or with any U.S. federal, California, New York or Delaware (solely with respect to the DGCL) governmental agency or body or court is required for the execution and delivery of the Operative Documents, the offer and sale by the Company of the Securities or the consummation by the Company of the transactions contemplated by the Purchase Agreement or the Indenture, except (i) such as have been obtained under the Securities Act, (ii) such as may be required under state securities or Blue Sky laws, and (iii) as contemplated by the Operative Documents.

13. Assuming the accuracy of the Initial Purchasers’ representations contained in the Purchase Agreement and the accuracy of the Company’s representations contained in the Purchase Agreement, no registration of the Securities or the Shares is required under the Securities Act for the sale of the Securities by the Company to the Initial Purchasers pursuant to the Purchase Agreement and the Indenture or for the initial resale of the Securities by the Initial Purchasers in the manner contemplated by the Purchase Agreement, the General Disclosure Package and the Final Offering Memorandum, and it is not necessary to qualify the Indenture under the Trust Indenture Act of 1939 (it being understood that, in each case, no opinion is expressed as to any subsequent resale of the Securities or the consequences thereof).

We have participated in conferences with certain officers and other representatives of the Company, representatives of the Initial Purchasers, counsel for the Initial Purchasers and representatives of the independent certified public accountants of the Company at which the contents of the 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 Disclosure Package or the Final Offering Memorandum (except to the extent of our statements in paragraphs 9 and 10 of our opinion letter separately delivered to you today pursuant to the Purchase Agreement), 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:

(i)    the Disclosure Package, as of 11:30 p.m. New York time on November 14, 2017, contained 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

(ii)    the Final Offering Memorandum, as of its date or as of the date hereof, contained or contains 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.

Ladies and Gentlemen:

The undersigned understands that you and certain other firms (the “Initial Purchasers”) propose to enter into a Purchase Agreement (the “Purchase Agreement”) providing for the purchase by the Initial Purchasers of 1.375% Convertible Senior Notes due 2023    (the “Notes”) of Rambus Inc., a Delaware corporation (the “Company”). The Notes will be convertible into cash and, if designated by the Company, shares of the Company’s common stock, par value $0.001 per share (the “Common Stock”), and the Initial Purchasers propose to reoffer the Notes in Exempt Resales (as such term is defined in the Purchaser 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, or

Any Common Stock received upon exercise of options or vesting of restricted stock units granted to the undersigned also will be subject to this Lock-Up Letter Agreement; provided that, notwithstanding the foregoing, during the last 30 days of the Lock-Up Period, offers, sales or other dispositions by the undersigned (i) together with all other individuals subject to a lock-up agreement substantially similar hereto, of up to an aggregate of 50,000 shares of Common Stock issued upon the exercise of options during the Lock-Up Period that will expire prior to the Lock-Up Period, (ii) together with all other individuals subject to a lock-up agreement substantially similar hereto, of up to an aggregate of 125,000 shares of Common Stock issued upon the vesting of restricted stock units during the Lock-Up Period, and (iii) to the Company of Common Stock upon a vesting event to pay required withholding taxes, shall not be subject to this Lock-Up Letter Agreement. Offers, sales or other dispositions of Common Stock pursuant to a written plan (a “Plan”) for trading securities in effect on the date hereof and disclosed to the Representatives will not be subject to this Lock-Up Letter Agreement if such Plan (i) was established pursuant to and in accordance with Rule 10b5-1(c) under the Securities Exchange Act of 1934, as amended and (ii) is not amended or modified during the Lock-Up Period. A transfer of Common Stock (i) as a bona fide gift or (ii) to a family member or trust, partnership or limited liability company for the direct or indirect benefit of such family member may be made, provided the donee or transferee, as applicable, agrees to be bound in writing by the terms of this Lock-Up Letter Agreement prior to such transfer and no filing by any party (donor, donee, transferor or transferee) under the Exchange Act shall be required or shall be voluntarily made in connection with such transfer (other than a filing on a Form 5 made after the expiration of the Lock-Up Period).

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 Notes, 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 an Purchase Agreement, the terms of which are subject to negotiation between the Company and the Initial Purchasers.
