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upon acceptance for payment of the Shares tendered herewith in accordance with the terms of the Offer and not properly withdrawn prior to the Expiration Date in accordance with the terms of the Offer, the undersigned hereby sells, assigns and transfers to or upon the order of Purchaser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
