Ladies and Gentlemen:

The undersigned hereby tenders to Blue Magpie Corporation, a Delaware corporation (“Purchaser”) and a wholly-owned subsidiary of Celgene Corporation, a Delaware corporation (“Celgene”), the above-described shares (collectively, the “Shares”) of common stock, par value $0.0001 per share, of Juno Therapeutics, Inc., a Delaware corporation (“Juno”), at a price of  $87.00 per Share, net to the seller in cash (the “Offer Price”), without interest and subject to any withholding of taxes in accordance with the Merger Agreement, upon the terms and subject to the conditions set forth in the Offer to Purchase, dated February 2, 2018 (the “Offer to Purchase”), receipt of which is hereby acknowledged, and this Letter of Transmittal (as it may be amended or supplemented from time to time, this “Letter of Transmittal” and, together with the Offer to Purchase, as it may be amended or supplemented from time to time, the “Offer”). The undersigned understands that Purchaser reserves the right to transfer or assign, from time to time, in whole or in part, to one or more of its affiliates, the right to purchase the Shares tendered herewith.

Upon the terms and subject to the conditions of the Offer (and if the Offer is extended or amended, the terms of any such extension or amendment), and effective upon acceptance for payment of the Shares tendered herewith in accordance with the terms of the Offer and not properly withdrawn prior to the Expiration Date in accordance with the terms of the Offer, the undersigned hereby sells, assigns and transfers to or upon the order of Purchaser all right, title and interest in and to all of the Shares that are being tendered hereby, distributions, rights, other Shares or other securities issued or issuable in respect thereof on or after February 2, 2018 (collectively, “Distributions”) and irrevocably constitutes and appoints Equiniti Trust Company (the “Depositary”) the true and lawful agent and attorney-in-fact of the undersigned with respect to such Shares (and all Distributions), with full power of substitution (such power of attorney being deemed to be an irrevocable power coupled with an interest), to (i) deliver certificates for such Shares (and any and all Distributions) or transfer ownership of such Shares (and any and all Distributions) on the account books maintained by the Depositary or DTC, together, in any such case, with all accompanying evidences of transfer and authenticity, to or upon the order of Purchaser, (ii) present such Shares (and any and all Distributions) for transfer on the books of Juno, and (iii) receive all benefits and otherwise exercise all rights of beneficial ownership of such Shares (and any and all Distributions), all in accordance with the terms and subject to the conditions of the Offer.

By executing this Letter of Transmittal (or taking action resulting in the delivery of an Agent’s Message), the undersigned hereby irrevocably appoints each of the designees of Purchaser in their respective capacities as officers of Purchaser, and any individual who shall thereafter succeed to any such office of Purchaser, and each of them, and any other designees of Purchaser, the attorneys-in-fact and proxies of the undersigned, each with full power of substitution, to vote at any annual or special meeting of Juno stockholders or any adjournment or postponement thereof or otherwise in such manner as each such attorney-in-fact and proxy or his or her substitute shall in his or her sole discretion deem proper with respect to, to execute any written consent concerning any matter as each such attorney-in-fact and proxy or his or her substitute shall in his or her sole discretion deem proper with respect to, and to otherwise act as each such attorney-in-fact and proxy or his or her substitute shall in his or her sole discretion deem proper with respect to, all of the Shares (and any and all Distributions) tendered hereby and accepted for payment by Purchaser. This appointment will be effective if and when, and only to the extent that, Purchaser accepts such Shares for payment pursuant to the Offer. This power of attorney and proxy are irrevocable and are granted in consideration of the acceptance for payment of such Shares in accordance with the terms of the Offer. Such acceptance for payment shall, without further action, revoke any prior powers of attorney and proxies granted by the undersigned at any time with respect to such Shares (and any and all Distributions), and no subsequent powers of attorney, proxies, consents or revocations may be given by the undersigned with respect thereto (and, if given, will not be deemed effective).

Purchaser reserves the right to require that, in order for the Shares to be deemed validly tendered, immediately upon Purchaser’s acceptance for payment of such Shares, Purchaser must be able to exercise full voting, consent and other rights with respect to such Shares (and any and all Distributions), including voting at any meeting of Juno stockholders or executing a written consent concerning any matter.

The undersigned hereby represents and warrants that the undersigned has full power and authority to tender, sell, assign and transfer the Shares tendered hereby and all Distributions and that, when the same are accepted for payment by Purchaser, Purchaser will acquire good, marketable and unencumbered title thereto and to all Distributions, free and clear of all liens, restrictions, charges and encumbrances and the same will not be subject to any adverse claims. The undersigned hereby represents and warrants that the undersigned is the registered owner of the Shares, or the Share Certificate(s) have been endorsed to the undersigned in blank, or the undersigned is a participant in DTC whose name appears on a security position

listing as the owner of the Shares. The undersigned will, upon request, execute and deliver any additional documents deemed by the Depositary or Purchaser to be necessary or desirable to complete the sale, assignment and transfer of the Shares tendered hereby and all Distributions. In addition, the undersigned shall remit and transfer promptly to the Depositary for the account of Purchaser all Distributions in respect of the Shares tendered hereby, accompanied by appropriate documentation of transfer, and, pending such remittance and transfer or appropriate assurance thereof, Purchaser shall be entitled to all rights and privileges as owner of each such Distribution and may withhold the entire purchase price of the Shares tendered hereby or deduct from such purchase price, the amount or value of such Distribution as determined by Purchaser in its sole discretion.

All authority herein conferred or agreed to be conferred shall survive the death or incapacity of the undersigned, and any obligation of the undersigned hereunder shall be binding upon the heirs, executors, administrators, personal representatives, trustees in bankruptcy, successors and assigns of the undersigned. Except as stated in the Offer, this tender is irrevocable.

The undersigned understands that the acceptance for payment by Purchaser of Shares tendered pursuant to one of the procedures described in “The Tender Offer—Section 3. Procedures for Tendering Shares” of the Offer to Purchase and in the Instructions hereto will constitute a binding agreement between the undersigned and Purchaser upon the terms and subject to the conditions of the Offer, which agreement will be governed by, and construed in accordance with, the laws of the State of New York.

Purchaser reserves the absolute right to reject any and all tenders determined by it not to be in proper form or the acceptance for payment of or payment for which may be unlawful. Purchaser also reserves the absolute right to waive any defect or irregularity in the surrender of any Shares or Share Certificate(s) whether or not similar defects or irregularities are waived in the case of any other stockholder. A surrender will not be deemed to have been validly made until all defects and irregularities have been cured or waived. Purchaser and the Depositary shall make reasonable efforts to notify any person of any defect in any Letter of Transmittal submitted to the Depositary.

3. Inadequate Space.   If the space provided herein is inadequate, the certificate numbers and/or the number of Shares and any other required information should be listed on a separate signed schedule attached hereto.

The purpose for this form is explained below under “Important Tax Information.” The United States Holder must, under penalties of perjury,

8

certify that such number is correct and that such holder is not subject to backup withholding of U.S. federal income tax or, alternatively, establish another basis for exemption from backup withholding. Failure to provide the information requested on the Form W-9 may subject the tendering United States Holder to a $50 penalty imposed by the Internal Revenue Service and to federal income tax backup withholding at the applicable federal withholding rate (currently 24%) of any payments made to the United States Holder or other payee.

Certain stockholders (including, for example, corporations, financial institutions, tax-exempt entities and IRA plans) are not subject to backup withholding. A Non-United States Holder (as defined in the Offer to Purchase) should submit an appropriate and properly completed IRS Form W-8, a copy of which may be obtained from the Depositary, in order to avoid backup withholding.

9. Requests for Assistance or Additional Copies.   Questions and requests for assistance or additional copies of the Offer to Purchase, this Letter of Transmittal, the Notice of Guaranteed Delivery or IRS Form W-9 may be directed to the Information Agent at the address and phone numbers set forth below, or from brokers, dealers, commercial banks or trust companies.

10. Waiver of Conditions.   Subject to the terms and conditions of the Merger Agreement, Purchaser reserves the right, in its sole discretion, to waive, at any time or from time to time, any of the specified conditions of the Offer, in whole or in part, in the case of any Shares tendered.

11. Lost, Destroyed or Stolen Certificates.   If your certificates are lost, destroyed or stolen please check the box and complete the box entitled “Description of Shares Tendered”. A $75.00 lost certificate replacement fee must be mailed in with your completed Letter of Transmittal. If there are additional forms or fees needed, you will be contacted.

12. Withdrawal of Shares Tendered.   Shares tendered pursuant to the Offer may be withdrawn at any time prior to the Expiration Date, pursuant to the procedures set forth in “The Tender Offer—Section 4. Withdrawal Rights” of the Offer to Purchase. After an effective withdrawal, you may resubmit to the Depositary Agent a completed replacement of this document and any other documents required by the Offer for properly tendering Shares prior to the Expiration Date.

Important: This Letter of Transmittal together with any required signature guarantees, and any other required documents, must be received by the Depositary prior to the Expiration Date and certificates for tendered Shares must be received by the Depositary prior to the expiration time of the Offer on the Expiration Date, or the tendering stockholder must comply with the procedures for guaranteed delivery.

IMPORTANT TAX INFORMATION

Payments made to a United States Holder (as defined in the Offer to Purchase) in connection with the Offer or the Merger will be subject to information reporting and U.S. federal backup withholding (currently at a rate of 24%) unless (i) in the case of backup withholding, such United States Holder provides an accurate TIN (which for an individual is a Social Security Number) on the enclosed Form W-9 and any other required information or (ii) such United States Holder is a corporation or other exempt stockholder. Exempt stockholders, other than foreign persons, should furnish their TIN, enter their “Exempt payee” code and sign, date and return the Form W-9 to the Depositary or other applicable withholding agent. If the Depositary or other applicable withholding agent is not provided with the correct TIN, the stockholder may be subject to a $50 penalty imposed by the Internal Revenue Service. In addition, payments that are made to such stockholder may be subject to backup withholding based on 24% of the reportable amount.

Payments made to a Non-United States Holder (as defined in the Offer to Purchase) in connection with the Offer or the Merger may be subject to backup withholding (currently at a rate of 24%) unless the Non-United States Holder submits an appropriate and properly completed IRS Form W-8, attesting to that holder’s foreign status. Normally, a foreign individual or foreign corporation will provide a Form W-8BEN or Form W-8BEN-E, as applicable. Intermediary entities will provide a Form W-8IMY for the entity and a Form W-8BEN, Form W-8BEN-E, or Form W-9, as applicable, for each beneficial owner along with a withholding statement. Such a Form W-8 may be obtained from the Depositary.

If backup withholding applies, the Depositary or other applicable withholding agent is required to withhold 24% of any reportable payments made to the stockholder. Backup withholding is not an additional tax and may be refunded or credited by the Internal Revenue Service to the extent it results in an overpayment of tax, provided such holder furnishes the required information to the Internal Revenue Service in a timely manner. In addition, certain penalties apply for failure to provide correct information and for failure to include reportable payments in income. Each holder should consult with his or her own tax advisor as to his or her qualification for exemption from backup withholding and the procedure for obtaining such exemption.

The IRS Form W-9 is included herein.
