 <P STYLE="margin-top:0pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Item&nbsp;6.&nbsp;Indemnification of Directors and Officers. </B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Section&nbsp;145 of the Delaware General Corporation Law empowers a corporation to indemnify its directors and officers and to purchase
insurance with respect to liability arising out of their capacity or status as directors and officers, provided that the person acted in good faith and in a manner the person reasonably believed to be in our best interests, and, with respect to any
criminal action, had no reasonable cause to believe the person&#146;s actions were unlawful. The Delaware General Corporation Law further provides that the indemnification permitted thereunder shall not be deemed exclusive of any other rights to
which the directors and officers may be entitled under the corporation&#146;s bylaws, any agreement, a vote of stockholders or otherwise. The certificate of incorporation of the Registrant provides for the indemnification of the registrant&#146;s
directors and officers to the fullest extent permitted under the Delaware General Corporation Law. In addition, the bylaws of the Registrant require the Registrant to fully indemnify any person who was or is a party or is threatened to be made a
party to any threatened, pending or completed action, suit or proceeding (whether civil, criminal, administrative or investigative) by reason of the fact that such person is or was a director or officer of the Registrant, or is or was a director or
officer of the Registrant serving at the Registrant&#146;s request as a director, officer, employee, or agent of another corporation, partnership, joint venture, trust, or other enterprise, against expenses (including attorney&#146;s fees),
judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, to the fullest extent permitted by applicable law. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Section&nbsp;102(b)(7) of the Delaware General Corporation Law permits a corporation to provide in its certificate of incorporation that a
director of the corporation shall not be personally liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except (1)&nbsp;for any breach of the director&#146;s duty of loyalty to the
corporation or its stockholders, (2)&nbsp;for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (3)&nbsp;for payments of unlawful dividends or unlawful stock repurchases or redemptions, or
(4)&nbsp;for any transaction from which the director derived an improper personal benefit. The Registrant&#146;s certificate of incorporation provides that the Registrant&#146;s directors shall not be personally liable to it or its stockholders for
monetary damages for breach of fiduciary duty as a director and that if the Delaware General Corporation Law is amended to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of the
registrant&#146;s directors shall be eliminated or limited to the fullest extent permitted by the Delaware General Corporation Law, as so amended. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:8%; font-size:10pt; font-family:Times New Roman">As permitted by the Delaware General Corporation Law, the Registrant has entered into separate indemnification agreements with each of the
Registrant&#146;s directors and certain of the Registrant&#146;s officers, which require the Registrant, among other things, to indemnify them against certain liabilities which may arise by reason of their in addition to the indemnification provided
for in its amended and restated certificate of incorporation and amended and restated bylaws, and intends to enter into indemnification agreements with any new directors and executive officers in the future. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:8%; font-size:10pt; font-family:Times New Roman">The Registrant has purchased and intends to maintain insurance policies under which its directors and officers are insured, within the limits
and subject to the limitations of those policies, against certain expenses in connection with the defense of, and certain liabilities which might be imposed as a result of, actions, suits or proceedings to which they are parties by reason of being
or having been directors or officers. The coverage provided by these policies may apply whether or not the registrant would have the power to indemnify such person against such liability under the provisions of the Delaware General Corporation Law.
</P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:8%; font-size:10pt; font-family:Times New Roman">These indemnification provisions and the indemnification agreements entered into between the registrant and the registrant&#146;s
officers and directors may be sufficiently broad to permit indemnification of the registrant&#146;s officers and directors for liabilities (including reimbursement of expenses incurred) arising under the Securities Act of 1933, as amended. </P>

as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the provisions described under &#147;Item 6&#151;Indemnification of Directors
and Officers,&#148; or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore,
unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of
any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel, the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue. </P>

INFORMATION
REQUIRED IN REGISTRATION STATEMENT
Item 3. Incorporation of Documents by Reference.
Juno Therapeutics, Inc. (the "Registrant") hereby incorporates by reference into this Registration Statement the following documents
previously filed with the Securities and Exchange Commission (the "Commission"):
(1) The Registrant's Prospectus dated
December 18, 2014, filed with the Commission on December 19, 2014 pursuant to Rule 424(b) under the Securities Act, relating to the Registration Statement on Form S-1, as amended (File No. 333-200293), which contains the
Registrant's audited financial statements for the latest fiscal year for which such statements have been filed; and
(2) The
description of the Registrant's Common Stock contained in the Company's Registration Statement on Form 8-A (File No. 001-36781) filed with the Commission on December 10, 2014, pursuant to Section 12(b) of the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), including any amendment or report filed for the purpose of updating such description.
All documents filed by the Registrant pursuant to Sections 13(a), 13(c), 14 and 15(d) of the Exchange Act on or after the date of this
Registration Statement and prior to the filing of a post-effective amendment to this Registration Statement that indicates that all securities offered have been sold or that deregisters all securities then remaining unsold shall be deemed to be
incorporated by reference in this Registration Statement and to be a part hereof from the date of filing of such documents;
provided
,
however
, that documents or information deemed to have been furnished and not filed in accordance with
the rules of the Commission shall not be deemed incorporated by reference into this Registration Statement. Any statement contained in a document incorporated or deemed to be incorporated by reference herein shall be deemed to be modified or
superseded for purposes of this Registration Statement to the extent that a statement contained herein or in any subsequently filed document which also is deemed to be incorporated by reference herein modifies or supersedes such statement. Any such
statement so modified or superseded shall not be deemed, except as so modified or superseded, to constitute a part of this Registration Statement.
Item 4. Description of Securities.
Not applicable.
Item 5. Interests
of Named Experts and Counsel.
The validity of the issuance of the shares of the Registrant's common stock offered hereby has been
passed upon by Wilson Sonsini Goodrich & Rosati, P.C. Certain members of, and investment partnerships comprised of members of, and persons associated with Wilson Sonsini Goodrich & Rosati, P.C. own an aggregate of 86,922 shares of
the Registrant's capital stock, representing less than 1% of all outstanding shares of Registrant's capital stock.
Item 6. Indemnification of Directors and Officers.
Section 145 of the Delaware General Corporation Law empowers a corporation to indemnify its directors and officers and to purchase
insurance with respect to liability arising out of their capacity or status as directors and officers, provided that the person acted in good faith and in a manner the person reasonably believed to be in our best interests, and, with respect to any
criminal action, had no reasonable cause to believe the person's actions were unlawful. The Delaware General Corporation Law further provides that the indemnification permitted thereunder shall not be deemed exclusive of any other rights to
which the directors and officers may be entitled under the corporation's bylaws, any agreement, a vote of stockholders or otherwise. The certificate of incorporation of the Registrant provides for the indemnification of the registrant's
directors and officers to the fullest extent permitted under the Delaware General Corporation Law. In addition, the bylaws of the Registrant require the Registrant to fully indemnify any person who was or is a party or is threatened to be made a
party to any threatened, pending or completed action, suit or proceeding (whether civil, criminal, administrative or investigative) by reason of the fact that such person is or was a director or officer of the Registrant, or is or was a director or
officer of the Registrant serving at the Registrant's request as a director, officer, employee, or agent of another corporation, partnership, joint venture, trust, or other enterprise, against expenses (including attorney's fees),
judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, to the fullest extent permitted by applicable law.
Section 102(b)(7) of the Delaware General Corporation Law permits a corporation to provide in its certificate of incorporation that a
director of the corporation shall not be personally liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except (1) for any breach of the director's duty of loyalty to the
corporation or its stockholders, (2) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (3) for payments of unlawful dividends or unlawful stock repurchases or redemptions, or
(4) for any transaction from which the director derived an improper personal benefit. The Registrant's certificate of incorporation provides that the Registrant's directors shall not be personally liable to it or its stockholders for
monetary damages for breach of fiduciary duty as a director and that if the Delaware General Corporation Law is amended to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of the
registrant's directors shall be eliminated or limited to the fullest extent permitted by the Delaware General Corporation Law, as so amended.
As permitted by the Delaware General Corporation Law, the Registrant has entered into separate indemnification agreements with each of the
Registrant's directors and certain of the Registrant's officers, which require the Registrant, among other things, to indemnify them against certain liabilities which may arise by reason of their in addition to the indemnification provided
for in its amended and restated certificate of incorporation and amended and restated bylaws, and intends to enter into indemnification agreements with any new directors and executive officers in the future.
The Registrant has purchased and intends to maintain insurance policies under which its directors and officers are insured, within the limits
and subject to the limitations of those policies, against certain expenses in connection with the defense of, and certain liabilities which might be imposed as a result of, actions, suits or proceedings to which they are parties by reason of being
or having been directors or officers. The coverage provided by these policies may apply whether or not the registrant would have the power to indemnify such person against such liability under the provisions of the Delaware General Corporation Law.
These indemnification provisions and the indemnification agreements entered into between the registrant and the registrant's
officers and directors may be sufficiently broad to permit indemnification of the registrant's officers and directors for liabilities (including reimbursement of expenses incurred) arising under the Securities Act of 1933, as amended.
Item 7. Exemption from Registration Claimed.
Not applicable.
Item 8. Exhibits.
The Exhibit Index to this Registration Statement is incorporated herein by reference as the list of exhibits required as part of this
Registration Statement.
Item 9. Undertakings.
A. The undersigned Registrant hereby undertakes:
(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration
Statement:
(i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;
(ii) To reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or the
most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement. Notwithstanding the foregoing, any increase or decrease in the volume
of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed
with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table
in the effective Registration Statement;
(iii) To include any material information with respect to the plan of
distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement.
Provided, however
, that paragraphs (A)(1)(i) and (A)(1)(ii) do not apply if the information required to be included in a
post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated
by reference in this Registration Statement.
(2) That, for the purpose of determining any liability under the Securities
Act of 1933, each such post-effective amendment shall be deemed to be a new Registration Statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering
thereof.
(3) To remove from registration by means of a post-effective amendment any of the securities being registered
which remain unsold at the termination of the offering.
B. The undersigned Registrant hereby undertakes that, for purposes of determining
any liability under the Securities Act of 1933, each filing of the Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the Registration Statement shall be deemed to be a new Registration Statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be the initial
bona fide
offering thereof.
C. Insofar
as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the provisions described under "Item 6—Indemnification of Directors
and Officers," or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore,
unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of
any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel, the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.
SIGNATURES
Pursuant to the requirements of the Securities Act of 1933, as amended, the Registrant certifies that it has reasonable grounds to believe
that it meets all of the requirements for filing on Form S-8 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in Seattle, Washington, on the 19
th
day of December, 2014.
