The Company evaluated its securities for other-than-temporary
impairment and considers the decline in market value for the
securities to be primarily attributable to current economic and
market conditions. For the debt securities, it is not more likely
than not that the Company will be required to sell the securities,
and the Company does not intend to do so prior to the recovery of
the amortized cost basis. The unrealized loss for equity securities
is related to the Company’s investment in Fate Therapeutics.
The Company has evaluated the near-term prospects of the Fate
Therapeutics investment in relation to the severity and duration of
the impairment and based on that evaluation, the Company expects
that a recovery in the fair value to at least the cost basis of the
equity security will occur in an acceptable forecast period and has
the ability and intent to hold this investment until a recovery of
fair value. Based on this analysis, these marketable securities
were not considered to be other-than-temporarily impaired as of
March 31, 2016 and December 31, 2015, and the associated
unrealized losses were included in accumulated other comprehensive
income (loss).</p>

On January 8, 2016, the Company completed the acquisition of
100% of the outstanding equity in AbVitro. The Company paid
approximately $74.7 million in cash and issued an aggregate of
1,289,188 shares of the Company’s common stock valued at
$46.9 million based on the closing stock price on January 8,
2016 of $36.39 per share. An additional $2.2 million was recorded
as post-combination research and development expense in the first
quarter of 2016 in connection with the accelerated vesting of
employee stock options. Additionally, 24,446 restricted stock units
(“RSUs”) were granted to former AbVitro employees,
which shares are subject to monthly vesting over three years
following the closing of the transaction, contingent on such
employees continuing to provide services to the Company through
such vesting dates. These will be accounted for as post-acquisition
compensation expenses. There are no milestone payment obligations
under the terms of the AbVitro acquisition.</p>

The fair value of the acquired in-process research and development
(“IPR&D”) has been estimated using the replacement
cost method. Under this method, the Company estimated the cost to
recreate the technology and derived an estimated value to develop
the technology. IPR&D assets are required to be classified as
indefinite-lived assets until they become definite lived assets
upon the successful completion or the abandonment of the associated
research and development effort. Accordingly, during the
development period after the date of acquisition, we do not expect
these assets to begin to be amortized until the first instance they
are used for translational assays. At that time, the Company will
determine the useful life of the asset and begin amortization. If
the associated research and development effort is abandoned, the
related IPR&D assets will be written-off and an impairment
charge recorded.</p>

The excess of the purchase price over the estimated fair value of
the tangible net assets and identifiable intangible assets acquired
was recorded as goodwill. The factors contributing to the
recognition of the amount of goodwill in the AbVitro acquisition
include the ability to accelerate the generation of binders that
recognize known targets and discover novel cancer antigen targets.
The acquisition also provides the Company with the ability to
utilize translational assays to provide a better understanding of
the natural immune response to cancer as well as to interrogate and
monitor the immune system of patients during treatment. None of the
goodwill is expected to be deductible for income tax purposes.</p>

<td valign="top" align="left">Represents the number of shares that
would be issued if the success payment valuation date had been
March 31, 2015. The Company’s common stock price per
share was $60.66 at March 31, 2015 which would have resulted
in a success payment of $205 million ($125 million for FHCRC and
$80 million for MSK). The number of shares issued, for the purpose
of this presentation, is calculated by dividing the success payment
by the stock price per share on the valuation date. At
March 31, 2016 the Company’s stock price was below the
threshold that would require additional payments to FHCRC or MSK,
therefore no shares are included.</td>

Juno Therapeutics, Inc. (the “Company”) was
incorporated in Delaware on August 5, 2013 as FC Therapeutics,
Inc., and changed its name to Juno Therapeutics, Inc. on
October 23, 2013. The Company is building a fully-integrated
biopharmaceutical company focused on re-engaging the body’s
immune system to revolutionize the treatment of cancer. Founded on
the vision that the use of human cells as therapeutic entities will
drive one of the next important phases in medicine, the Company is
developing cell-based cancer immunotherapies based on its chimeric
antigen receptor (“CAR”) and high-affinity T cell
receptor (“TCR”) technologies to genetically engineer T
cells to recognize and kill cancer cells.</p>
<p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt 'Times New Roman'; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px">
In January 2016, the Company acquired AbVitro, Inc.,
(“AbVitro”) a company with a leading next-generation
single cell sequencing platform. See Note 2, Acquisition. The
AbVitro acquisition is intended to augment the Company’s
capabilities to create engineered T cells against a broad
array of cancer targets. The Company will initially use this
technology in its translation research assays, to find and generate
fully-human TCRs and antibodies, and to find novel targets.</p>

The Company is subject to a number of risks similar to other
biopharmaceutical companies in the early stage, including, but not
limited to, possible failure of preclinical testing or clinical
trials, the need to obtain marketing approval for its product
candidates, competitors developing new technological innovations,
the need to successfully commercialize and gain market acceptance
of the Company’s products, protection of proprietary
technology, and the need to obtain adequate additional funding. If
the Company, or any commercialization partner for the
Company’s product candidates, does not successfully
commercialize any of the Company’s product candidates, the
Company will not be able to generate product revenue or achieve
profitability. As of March 31, 2016, the Company had an
accumulated deficit of $656.8 million.</p>

The financial data as of December 31, 2015 is derived from the
Company’s audited financial statements, which are included in
the Company’s Annual Report on Form 10-K, which was filed
with the Securities and Exchange Commission (the “SEC”)
on February 29, 2016 (the “2015 Annual Report”),
and should be read in conjunction with the audited financial
statements and notes thereto. The Company’s significant
accounting policies are described in Note 2 to the financial
statements included in the 2015 Annual Report. Certain prior period
amounts have been reclassified to conform to the current period
presentation. For the three months ended March 31, 2015, $0.7
million was reclassified from litigation to general and
administrative on the condensed consolidated statements of
operations. This reclassification does not have a material impact
on the Company’s condensed consolidated financial
statements.</p>

The accompanying interim balance sheet as of March 31, 2016,
the statements of operations, comprehensive loss and cash flows for
the three months ended March 31, 2016 and 2015 and the related

condensed consolidated financial statements have been prepared in
accordance with U.S. generally accepted accounting principles
(“GAAP”). In management’s opinion, the unaudited
interim condensed consolidated financial statements have been
prepared on the same basis as the audited financial statements and
include all adjustments, which include only normal recurring
adjustments, necessary for the fair presentation of the
Company’s financial position as of March 31, 2016 and
its results of operations, comprehensive loss, and cash flows for
the three months ended March 31, 2016 and 2015. The results
for the three months ended March 31, 2016 and 2015 are not
necessarily indicative of the results expected for the full fiscal
year or any other interim period.</p>

In March 2016, following the filing of the 2015 Annual Report,
Celgene exercised its annual right to purchase additional shares of

ownership interest in the Company. Celgene purchased 1,137,593
shares at a price of $41.32 per share, for an aggregate cash
purchase price of $47.0 million. As Celgene did not exercise the
top-up right in full to reach 10% ownership that would have been
permitted by the top-up right, the top-up right that will be
triggered by the filing of the Company’s Annual Report on
Form 10-K for the fiscal year ending December 31, 2016 will
only permit Celgene to top-up its ownership stake of the
Company’s common stock to 9.76%.</p>

In October 2013, the Company entered into a collaboration agreement
with the Fred Hutchinson Cancer Research Center
(“FHCRC”) focused on research and development of cancer
immunotherapy products and a license agreement pertaining to
certain patent rights. The Company also granted FHCRC rights to
certain share-based success payments. The collaboration agreement,
license agreement, the share-based success payments, and the
Company’s accounting analysis pertaining to these agreements
and share-based success payments, are described in Note 4 of the
financial statements included in the 2015 Annual Report. In
December 2015, the Company entered into an agreement with FHCRC to
support the establishment of a clinical immunotherapy trial
unit.</p>

Excluding the expense or gain related to success payment
obligations, the Company recognized $4.5 million and $2.0 million
of research and development expenses in connection with its
collaboration and funding agreements with FHCRC for the three
months ended March 31, 2016 and 2015, respectively.</p>
<p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt 'Times New Roman'; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px">
The estimated fair value of the total success payment obligation to
FHCRC, after giving effect to the success payments achieved and
paid in December 2015, was approximately $56.1 million and $67.3
million as of March 31, 2016 and December 31, 2015,
respectively. With respect to the FHCRC success payment
obligations, the Company recognized a gain of $4.7 million and
expense of $27.2 million in the three months ended March 31,
2016 and 2015, respectively, which was recorded in research and
development expense. The gain and expense recorded represents the
change in the FHCRC success payment liability during such periods,
and three months of accrued expenses. The FHCRC success payment
liabilities on the condensed consolidated balance sheets as of
March 31, 2016 and December 31, 2015 were $29.0 million
and $33.8 million, respectively.</p>

The Company’s liability for share-based success payments
under the FHCRC collaboration is carried at fair value and
recognized as expense over the term of the six-year collaboration
agreement. To determine the estimated fair value of the success
payment liability, the Company uses a Monte Carlo simulation
methodology which models the future movement of stock prices based
on several key variables. The following variables were incorporated
in the calculation of the estimated fair value of the success
payment liability as of the following balance sheet dates:</p>

agreement with Memorial Sloan Kettering Cancer Center
(“MSK”) focused on research and development relating to
CAR T cell technology and a license agreement pertaining to certain
patent rights and intellectual property rights related to certain
know-how. The Company also granted MSK rights to certain
share-based success payments. The sponsored research agreement,
license agreement, the share-based success payments, and the
Company’s accounting analysis pertaining to these agreements

Excluding the expense or gain related to success payment

The estimated fair value of the total success payment obligation to
MSK, after giving effect to the success payment achieved in
December 2015 and paid in March 2016, was approximately $33.7
million and $48.9 million as of March 31, 2016 and
December 31, 2015, respectively. With respect to the MSK
success payment obligations, the Company recognized a gain of $1.9
million and expense of $11.7 million in the three months ended
March 31, 2016 and 2015, respectively, which were recorded in
research and development expense. The gain and expense recorded
represents the change in the MSK success payment liability during
such periods, and three months of accrued expense. The MSK success
payment liabilities on the condensed consolidated balance sheets as
of March 31, 2016 and December 31, 2015 were $19.7
million and $31.0 million, respectively.</p>

The Company’s liability for share-based success payments
under the MSK collaboration is carried at fair value and recognized
as expense over the term of the five-year collaboration agreement.
To determine the estimated fair value of the success payment
liability, the Company uses a Monte Carlo simulation methodology
which models the future movement of stock prices based on several
key variables. The following variables were incorporated in the
calculation of the estimated fair value of the success payment
liability as of the following balance sheet dates:</p>

As of March 31, 2016 and December 31, 2015, the estimated
fair value of the success payment obligations, after giving effect

approximately $89.8 million and $116.2 million, respectively.
Included in research and development expense for the three months
ended March 31, 2016 and 2015 was a gain of $6.6 million and
an expense of $38.9 million, respectively, related to success
payments. See Note 3, Collaboration and License Agreements, to

The Company utilizes significant estimates and assumptions in
determining the estimated success payment liability and associated

In connection with the acquisitions of Stage Cell Therapeutics GmbH
(“Stage”) and X-Body, Inc. (“X-Body”) in
the second quarter of 2015, the Company agreed to pay additional
amounts based on the achievement of certain milestones. This
contingent consideration is measured at fair value and is based on
significant inputs not observable in the market, which represents a
Level 3 measurement within the fair value hierarchy. The valuation
of contingent consideration uses assumptions the Company believes
would be made by a market participant. The Company assesses these
estimates on an on-going basis as additional data impacting the
assumptions is obtained.</p>
<p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt 'Times New Roman'; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px">
Contingent consideration may change significantly as development
progresses and additional data are obtained, impacting the
Company’s assumptions regarding probabilities of successful
achievement of related milestones used to estimate the fair value
of the liability and the timing in which they are expected to be
achieved. In evaluating the fair value information, judgment is
required to interpret the data used to develop the estimates. The
estimates of fair value may not be indicative of the amounts that
could be realized in a current market exchange. Accordingly, the
use of different market assumptions and/or different valuation
techniques could result in materially different fair value
estimates.</p>

The significant unobservable inputs used in the measurement of fair
value of the Company’s contingent consideration are
probabilities of successful achievement of the milestones, the
period in which these milestones are expected to be achieved
ranging from 2016 to 2043, and a discount rate of 17%. Significant
increases or decreases in any of the probabilities of success and
other inputs would result in a significantly higher or lower fair
value measurement, respectively.</p>

As of March 31, 2016, the estimated fair values of the
contingent consideration associated with the Stage and X-Body
acquisitions were $29.6 million and $6.7 million, respectively. The
Company recognized a gain of $1.0 million, which was recorded in
research and development expense, in the three months ended
March 31, 2016 related to the change in fair value of the
contingent consideration.</p>

<b>8. Income Taxes</b></p>
<p style="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">
The Company recorded an income tax benefit of $7.4 million on a
pre-tax loss of $78.5 million for the three months ended
March 31, 2016. Of the total income tax benefit, $6.7 million
relates to the release of valuation allowance on the U.S. deferred
tax assets as a result of the deferred tax liabilities established
for intangible assets from the acquisition of AbVitro, net of tax
attributes. The remainder relates to the benefit associated with
the net loss incurred by the Company’s German subsidiary in
the three months ended March 31, 2016.</p>
<p style="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">
The Company maintains a full valuation allowance on its net U.S.
deferred tax assets. The assessment regarding whether a valuation
allowance is required considers both positive and negative evidence
when determining whether it is more-likely-than-not that deferred
tax assets are recoverable. In making this assessment, significant
weight is given to evidence that can be objectively verified. In
its evaluation, the Company considered its cumulative loss in
recent years and its forecasted losses in the near-term as
significant negative evidence. Based upon a review of the four
sources of income identified within ASC 740, the Company determined
that the negative evidence outweighed the positive evidence and a
full valuation allowance on its U.S. net deferred tax assets will
be maintained. The Company will continue to assess the
realizability of its deferred tax assets going forward and will
adjust the valuation allowance as needed. The Company has
determined that it is more-likely-than-not that it will realize the
benefit of the losses for its German subsidiary and has not
recorded a valuation allowance against the German deferred tax
assets.</p>
<p style="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">
The Company follows the provisions of ASC 740, <i>Accounting for
Income Taxes</i>, and the accounting guidance related to accounting
for uncertainty in income taxes. The Company determines its
uncertain tax positions based on a determination of whether and how
much of a tax benefit taken by the Company in its tax filings or
positions is more likely than not to be sustained upon examination
by the relevant income tax authorities. The Company has not, as
yet, conducted a study of tax credit carryforwards. Such a study,
if undertaken by the Company, would not result in a material
adjustment to the Company’s tax credit carryforwards. The
Company will recognize both accrued interest and penalties related
to unrecognized benefits in income tax expense. The Company is
generally subject to examination by the U.S. federal and local
income tax authorities for all tax years in which a loss
carryforward is available and is subject to examination in Germany
for four years.</p>
<p style="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">
The Company applies judgment in the determination of the
consolidated financial statement recognition and measurement of tax
positions taken or expected to be taken in a tax return. As of
March 31, 2016 and December 31, 2015, the Company had no
material unrecognized or uncertain tax benefits.</p>

The Company has entered into various lease agreements for its
office, laboratory, and manufacturing spaces with original lease
periods expiring between 2016 and 2026. In addition to minimum
rent, certain leases require payment of real estate taxes,
insurance, common area maintenance charges and other executory
costs. These executory costs are not included in the table below.
Certain of these arrangements have free or escalating rent payment
provisions. The Company recognizes rent expense under such
arrangements on a straight-line basis over the effective term of
each lease.</p>

The preparation of the Company’s condensed consolidated
financial statements in conformity with GAAP requires management to
make estimates and assumptions that affect the amounts reported in
the consolidated financial statements and accompanying notes.
Actual results could differ from such estimates. See Note 2 to the
audited financial statements included in the 2015 Annual Report for
additional discussion of these estimates and assumptions.</p>

The Company utilizes significant estimates and assumptions in
determining the estimated success payment and contingent
consideration liabilities and associated expense or gain at each
balance sheet date. A small change in the Company’s stock
price may have a relatively large change in the estimated fair
value of the success payment liability and associated expense or
gain. Changes in the probabilities and estimated timing of
milestones used in the calculation of the contingent consideration
liability may have a relatively large impact of the resulting
liability and associated expense or gain.</p>

For employees, scientific founders, and directors, the expected
life was calculated based on the simplified method as permitted by
the SEC Staff Accounting Bulletin No. 110, <i>Share-Based Payment</i>.
For other service providers, the expected life was calculated using
the contractual term of the award. Management’s estimate of
expected volatility was based on available information about the
historical volatility of stocks of similar publicly-traded
companies for a period matching the expected term assumption and
its own historical and implied future volatility. The risk-free
interest rate is based on a U.S. Treasury instrument whose term is
consistent with the expected life of the stock options. In addition
to the assumptions above, management made an estimate of expected
forfeitures and is recognizing compensation costs only for those
equity awards expected to vest.</p>

In March 2016, the Financial Accounting Standards Board
(“FASB”) issued Accounting Standards Update
(“ASU”) No. 2016-09, <i>Compensation—Stock
Compensation (Topic 718)</i>, intended to simplify the accounting
for share-based payment transactions, including the income tax
consequences, classification of awards as either equity or
liabilities, and classification on the statement of cash flows. The
guidance is effective on January 1, 2017, with early adoption

Juno Therapeutics, Inc. (the “Company”) was
incorporated in Delaware on August 5, 2013 as FC Therapeutics,
Inc., and changed its name to Juno Therapeutics, Inc. on
October 23, 2013. The Company is building a fully-integrated
biopharmaceutical company focused on re-engaging the body’s
immune system to revolutionize the treatment of cancer. Founded on
the vision that the use of human cells as therapeutic entities will
drive one of the next important phases in medicine, the Company is
developing cell-based cancer immunotherapies based on its chimeric
antigen receptor (“CAR”) and high-affinity T cell
receptor (“TCR”) technologies to genetically engineer T
cells to recognize and kill cancer cells.</p>
<p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt 'Times New Roman'; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px">
In January 2016, the Company acquired AbVitro, Inc.,
(“AbVitro”) a company with a leading next-generation
single cell sequencing platform. See Note 2, Acquisition. The
AbVitro acquisition is intended to augment the Company’s
capabilities to create engineered T cells against a broad
array of cancer targets. The Company will initially use this
technology in its translation research assays, to find and generate
fully-human TCRs and antibodies, and to find novel targets.</p>

The Company is subject to a number of risks similar to other
biopharmaceutical companies in the early stage, including, but not
limited to, possible failure of preclinical testing or clinical
trials, the need to obtain marketing approval for its product
candidates, competitors developing new technological innovations,
the need to successfully commercialize and gain market acceptance
of the Company’s products, protection of proprietary
technology, and the need to obtain adequate additional funding. If
the Company, or any commercialization partner for the
Company’s product candidates, does not successfully
commercialize any of the Company’s product candidates, the
Company will not be able to generate product revenue or achieve
profitability. As of March 31, 2016, the Company had an
accumulated deficit of $656.8 million.</p>
<p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt 'Times New Roman'; WIDOWS: 1; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; -webkit-text-stroke-width: 0px">
The financial data as of December 31, 2015 is derived from the
Company’s audited financial statements, which are included in
the Company’s Annual Report on Form 10-K, which was filed
with the Securities and Exchange Commission (the “SEC”)
on February 29, 2016 (the “2015 Annual Report”),
and should be read in conjunction with the audited financial
statements and notes thereto. The Company’s significant
accounting policies are described in Note 2 to the financial
statements included in the 2015 Annual Report. Certain prior period
amounts have been reclassified to conform to the current period
presentation. For the three months ended March 31, 2015, $0.7
million was reclassified from litigation to general and
administrative on the condensed consolidated statements of
operations. This reclassification does not have a material impact
on the Company’s condensed consolidated financial
statements.</p>

The accompanying interim balance sheet as of March 31, 2016,
the statements of operations, comprehensive loss and cash flows for
the three months ended March 31, 2016 and 2015 and the related
footnote disclosures are unaudited. These unaudited interim
condensed consolidated financial statements have been prepared in
accordance with U.S. generally accepted accounting principles
(“GAAP”). In management’s opinion, the unaudited
interim condensed consolidated financial statements have been
prepared on the same basis as the audited financial statements and
include all adjustments, which include only normal recurring
adjustments, necessary for the fair presentation of the
Company’s financial position as of March 31, 2016 and
its results of operations, comprehensive loss, and cash flows for
the three months ended March 31, 2016 and 2015. The results
for the three months ended March 31, 2016 and 2015 are not
necessarily indicative of the results expected for the full fiscal
year or any other interim period.</p>

The preparation of the Company’s condensed consolidated
financial statements in conformity with GAAP requires management to
make estimates and assumptions that affect the amounts reported in
the consolidated financial statements and accompanying notes.
Actual results could differ from such estimates. See Note 2 to the
audited financial statements included in the 2015 Annual Report for
additional discussion of these estimates and assumptions.</p>

The Company utilizes significant estimates and assumptions in
determining the estimated success payment and contingent
consideration liabilities and associated expense or gain at each
balance sheet date. A small change in the Company’s stock
price may have a relatively large change in the estimated fair
value of the success payment liability and associated expense or
gain. Changes in the probabilities and estimated timing of
milestones used in the calculation of the contingent consideration
liability may have a relatively large impact of the resulting
liability and associated expense or gain.</p>

Basic and diluted net loss per share is calculated by dividing net
loss by the weighted average number of common shares outstanding
during the period, without consideration for common stock
equivalents. The Company’s potentially dilutive shares, which
include unvested restricted stock, unvested RSUs, options to
purchase common stock, and potential shares issued for success
payments, are considered to be common stock equivalents and are
only included in the calculation of diluted net loss per share when
their effect is dilutive.</p>

would be issued if the success payment valuation date had been
March 31, 2015. The Company’s common stock price per
share was $60.66 at March 31, 2015 which would have resulted
in a success payment of $205 million ($125 million for FHCRC and
$80 million for MSK). The number of shares issued, for the purpose
of this presentation, is calculated by dividing the success payment
by the stock price per share on the valuation date. At
March 31, 2016 the Company’s stock price was below the
threshold that would require additional payments to FHCRC or MSK,
therefore no shares are included.</td>

In April 2016, Celgene exercised its option to develop and
commercialize product candidates from the Company’s CD19
program outside North America and China. As a result, in April
2016, the Company and Celgene entered into a license agreement
pursuant to which Celgene received an exclusive, royalty-bearing
license to develop and commercialize therapeutic chimeric antigen
receptor product candidates from the Company’s CD19 program
in all territories outside of North America and China (the
“Celgene Territory”). The Company retains all rights to
develop further and commercialize such product candidates in North
America and China (the “Juno Territory”). The Company
and Celgene will generally share worldwide research and development
costs, while the Company will be responsible for commercialization
costs in the Juno Territory and Celgene will be responsible for
commercialization costs in the Celgene Territory. The Company has
the right to participate in specified commercialization activities
for licensed products arising from the CD19 program in certain
major European markets. Celgene has the right to participate in
specified commercialization activities in North America for
licensed products for certain indications under the CD19 program.
The Company received $50.0 million from Celgene as an upfront
payment upon the exercise of Celgene’s option to license
chimeric antigen receptor product candidates from the CD19 program.
The Company will also receive royalties from Celgene for chimeric
antigen receptor product candidates arising from the CD19 program
at a percentage in the mid-teens of net sales of such product
candidates in the Celgene Territory.</p>
