The following discussion and analysis of our financial condition and results of
operations should be read together with our consolidated financial statements
and related notes appearing elsewhere in this Annual Report on Form 10-K. In
addition to historical information, this discussion and analysis contains
forward-looking statements that involve risks, uncertainties and assumptions.
Our actual results may differ materially from those anticipated in these
forward-looking statements as a result of certain factors. We discuss factors
that we believe could cause or contribute to these differences below and
elsewhere in this Annual Report on Form 10-K, including those factors set forth
in the section entitled "Cautionary Note Regarding Forward-Looking Statements
and Industry Data" and in the section entitled "Risk Factors" in Part I, Item
1A.

Business Combination with Redx



On February 23, 2023, we announced that we had reached an agreement on the terms
of a recommended all-share combination, or the Scheme, between us and Redx
Pharma plc, or Redx, a clinical-stage biotechnology company incorporated in
England and Wales. In connection with the proposed transaction, (i) we entered
into a Co-operation Agreement with Redx on February 23, 2023 and (ii) we and one
of our wholly-owned subsidiaries, or Merger Sub, entered into a merger agreement
with RM Special Holdings 3, LLC, an entity controlled by Redmile Group, LLC, or
RM3, which contemplates a merger transaction among us, RM3 and Merger Sub, or
the Merger. The Merger and the Scheme are collectively referred to as the
Business Combination.

The Scheme will be implemented by means of a court-sanctioned scheme of
arrangement under the U.K. Companies Act 2006, as amended, immediately preceded
by the Merger, which together will result in Jounce owning the entire issued and
to be issued ordinary share capital of Redx. Under the terms of the Scheme,
holders of ordinary shares of Redx will be entitled to receive 0.2105 shares of
our common stock per ordinary share, subject to adjustment in the event of a
reverse stock split. Completion of the Business Combination is subject to
certain closing conditions, including, among others, (i) the approval of the
Scheme by a majority in number of Redx's shareholders present and voting (and
entitled to vote) at the meeting(s) of Redx's shareholders, representing not
less than 75 percent in value of the Redx shares held by such shareholders (or
the relevant class or classes thereof), (ii) the sanction of the Scheme by the
High Court of Justice of England and Wales, (iii) the approval of the issuance
of common stock by our stockholders in connection with the Business Combination,
and (iv) the Scheme becoming effective no later than July 31, 2023, which date
may be extended by mutual agreement of the parties. Subject to the approval of
our stockholders, we intend to conduct a 5:1 reverse stock split of our common
stock in conjunction with the Business Combination. We expect that, subject to
the satisfaction or waiver of all relevant conditions, the Business Combination
will be completed in the second quarter of 2023. However, there is no assurance
that the Business Combination will be consummated on the proposed terms, timing
or at all.

At or prior to the closing of the Business Combination, we plan to enter into a
Contingent Value Rights Agreement, or CVR Agreement, with a rights agent and a
representative, agent and attorney-in-fact of the holders of contingent value
rights, or CVRs. We expect to distribute CVRs to our stockholders of record and
holders of vested options to purchase common stock immediately prior to the
closing of the Business Combination in the form of a dividend in respect of each
outstanding share of our common stock or vested option to purchase common stock.
Each CVR will represent a contractual right to receive contingent cash payments
upon our receipt of 80% net proceeds payable, if any, from any license or
disposition of any or all rights to JTX-8064, vopratelimab, pimivalimab, and two
preclinical programs, JTX-1484 and JTX-2134, that occurs within one year of the
closing time of the Business Combination, subject to a six-month adjustment in
certain circumstances. In the event that no disposition is made within such
period, holders of CVRs will not receive any payment pursuant to the CVR
Agreement.

Jounce Programs



Our JTX-8064 program is being developed for patients with either PD-(L)1
inhibitor resistant or PD-(L)1 inhibitor sensitive tumors. JTX-8064 is the first
tumor-associated macrophage candidate to emerge from our Translational Science
Platform. JTX-8064 is a monoclonal antibody that binds to Leukocyte
Immunoglobulin Like Receptor B2, or LILRB2 (also known as ILT4), which is a cell
surface receptor expressed on macrophages and other myeloid cells. Our INNATE
clinical trial is a Phase 1/2 clinical trial of JTX-8064 as a monotherapy and in
combination with our PD-1 inhibitor, pimivalimab, in patients with solid tumors.
The Phase 2 portion of the INNATE trial is comprised of one monotherapy and
eight combination indication-specific expansion cohorts.

Vopratelimab is a clinical-stage monoclonal antibody that binds to and activates
the Inducible T cell CO-Stimulator, or ICOS, a protein on the surface of certain
T cells commonly found in many solid tumors. The SELECT trial is a randomized
Phase 2 proof-of-concept trial outside the United States evaluating two doses of
vopratelimab in combination with pimivalimab compared to pimivalimab alone in
biomarker-selected, second-line, PD-(L)1 inhibitor naive NSCLC patients.

Pimivalimab is a clinical-stage anti-PD-1 monoclonal antibody that we are
developing primarily for use in combination with our product candidates, as we
believe that combination therapy has the potential to be a mainstay of cancer
immunotherapy. We presented safety and preliminary efficacy data from our
monotherapy Phase 1 clinical trial of pimivalimab in 2019. Based on the results
of that clinical trial, we are using pimivalimab in combination with JTX-8064 in
INNATE and vopratelimab in SELECT.

GS-1811, formerly JTX-1811, which we sold to Gilead Sciences, Inc., or Gilead, in December 2022, was our fourth internally developed program to enter the clinic.

JTX-1484 is a monoclonal antibody designed to block human Leukocyte Immunoglobulin Like Receptor B4, or LILRB4 (also known as ILT3), on various myeloid cells which we believe may lead to reduced immune suppression and enhancement of T cell functionality. We are currently conducting investigational new drug application, or IND, enabling activities for JTX-1484.

JTX-2134 is a monoclonal antibody designed to block human LILRB1 on various myeloid cells, as well as on subsets of NK and T cells, which we believe may lead to reduced immune suppression and enhancement of T and NK cell functionality. We have identified a Development Candidate for the JTX-2134 program, but have decided not to initiate IND-enabling studies at this time.



Beyond our product candidates, we continue to advance and build our discovery
pipeline. We are discovering and developing next-generation immunotherapies by
leveraging our Translational Science Platform to systematically and
comprehensively interrogate cell types within the tumor microenvironment. Our
broad discovery pipeline includes multiple programs targeting myeloid cells such
as macrophages, T regulatory cells and non-immune cells. We believe that the use
of our Translational Science Platform to efficiently identify novel
immuno-oncology targets and advance them from discovery to IND stage is a
sustainable approach that we plan to continually apply across our broad
discovery pipeline and target selection process.

Since inception, our operations have focused on organizing and staffing our
company, business planning, raising capital, developing our Translational
Science Platform and conducting research, preclinical studies and clinical
trials. We do not have any products approved for sale. We are subject to a
number of risks comparable to those of other similar companies, including
dependence on key individuals; the need to develop commercially viable products;
competition from other companies, many of which are larger and better
capitalized; and the need to obtain adequate additional financing to fund the
development of our products. We have funded our operations primarily through
proceeds received from public offerings and private placements of our stock
totaling $389.5 million and payments from license and collaboration or asset
sale agreements totaling $467.0 million.

Due to our significant research and development expenditures, we have
accumulated substantial losses since our inception. As of December 31, 2022, we
had an accumulated deficit of $292.8 million. We expect to incur additional
losses in the future; however, during the pendency of the Business Combination
activities we do not expect to expand our research and development activities or
increase our business development costs.

Financial Operations Overview

Revenue



For the year ended December 31, 2022, we recognized $82.0 million of license
revenue under agreements with Gilead, $15.0 million of which related to the
achievement of a clinical and development milestone and $67.0 million of which
related to the sale of GS-1811 to Gilead. For the year ended December 31, 2021,
we recognized $26.9 million of license and collaboration revenue under the
Gilead License Agreement primarily relating to a $25.0 million milestone
achievement for FDA clearance of the IND for GS-1811 and $1.9 million related to
the completion of research and transition services.

In the future, we may generate revenue from product sales or collaboration
agreements, strategic alliances and licensing arrangements, including potential
milestone payments and royalties. We expect that our revenue will fluctuate from
quarter-to-quarter and year-to-year as a result of the timing and amount of
license fees, milestones, reimbursement of costs incurred and other payments, if
any, and product sales, to the extent any products are successfully
commercialized. If we or third parties fail to complete the development of our
product candidates in a timely manner or obtain regulatory approval for them,
our ability to generate future revenue, and our results of operations and
financial position, would be materially adversely affected.

Operating Expenses

Research and Development Expenses



Research and development expenses represent costs incurred by us for the
discovery, development and manufacture of our current and future product
candidates and include: external research and development expenses incurred
under arrangements with third parties, including contract research
organizations, contract manufacturing organizations, academic and non-profit
institutions and consultants; salaries and personnel-related costs, including
non-cash stock-based compensation expense; license fees to acquire in-process
technology and other expenses, which include direct and allocated expenses for
laboratory, facilities and other costs.

We use our employee and infrastructure resources across multiple research and
development programs and for identifying, testing and developing product
candidates from our Translational Science Platform. We manage certain activities
such as contract research and manufacture of our product candidates and
discovery programs through our third-party vendors.

At this time, we cannot reasonably estimate or know the nature, timing and
estimated costs of the efforts that will be necessary to complete the
development of our product candidates. We are also unable to predict when, if
ever, material net cash inflows will commence from sales of our product
candidates. This is due to the numerous risks and uncertainties associated with
developing such product candidates, including the uncertainty of:

•whether or not we complete the Business Combination;



•whether we successfully license or dispose of the assets subject to the CVR
Agreement if the Business Combination is completed, or if it is not completed,
whether we are able to seek business development opportunities for both the
JTX-8064 and vopratelimab programs;

•retention of key research and development personnel;

•establishing an appropriate safety profile with IND-enabling toxicology studies and clinical trials;

•the cost to acquire or make therapies to study in combination with our immunotherapies;

•successful completion of clinical trials;



•establishing agreements with third-party contract manufacturing organizations
for clinical supply for our clinical trials and commercial manufacturing, if our
product candidates are approved;

•receipt of marketing approvals from applicable regulatory authorities;

•commercializing products, if and when approved, whether alone or in collaboration with others;

•the costs associated with the development of any additional product candidates we acquire through third-party collaborations or identify through our Translational Science Platform;

•the terms and timing of any collaboration, license or other arrangement, including any milestone payments thereunder;

•obtaining and maintaining patent and trade secret protection and regulatory exclusivity for our products, if and when approved; and

•continued acceptable safety profiles of the products following approval.



A change in the outcome of any of these variables with respect to the
development of any of our product candidates would significantly change the
costs, timing and viability associated with the development of that product
candidate. We plan to increase our research and development expenses for the
foreseeable future as we advance our product candidates through clinical trials
and continue the enhancement of our Translational Science Platform and the
progression of our pipeline.

Due to the inherently unpredictable nature of preclinical and clinical
development, we do not allocate all of our internal research and development
expenses on a program-by-program basis as they primarily relate to personnel and
lab consumables costs that are deployed across multiple programs under
development. Our research and development expenses also include external costs,
which we do track on a program-by-program basis following the program's
nomination as a development candidate. We began incurring such external costs
for vopratelimab in 2015, pimivalimab in 2016, JTX-8064 in 2017, GS-1811 in 2019
and JTX-1484 in 2021.

Research and development activities account for a significant portion of our
operating expenses. We expect to incur research and development expenses over
the next several years as we implement our current business strategy and:

•continue our INNATE trial of JTX-8064 as a monotherapy and in combination with
pimivalimab (if such programs are not disposed of as contemplated by the CVR
Agreement);

•continue advancing JTX-1484 through IND-enabling activities (if such program is not disposed of as contemplated by the CVR Agreement);

•continue to identify and develop potential predictive biomarkers for our product candidates; and



•continue to develop and enhance our Translational Science Platform and advance
our pipeline of immunotherapy programs and our early research activities into
IND-enabling activities.

Product candidates in later stages of clinical development generally incur higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials.

General and Administrative Expenses



General and administrative expenses consist of salaries and personnel-related
costs, including non-cash stock-based compensation expense, for our personnel in
executive, business development, legal, finance and accounting, human resources
and other administrative functions, consulting fees, facility costs not
otherwise included in research and development expenses, fees paid for
accounting and tax services, insurance expenses and legal costs. Legal costs
include general corporate legal fees, patent legal fees and related costs. As a
result of the reduction in force we announced in February 2023, we anticipate
that our general and administrative expenses will increase in the first quarter
of 2023, as a result of severance and employee related costs, and may decrease
in the future due to overall reduced headcount.

Other Income, Net

Other income, net, consists primarily of interest and investment income on our cash, cash equivalents and investments.

Critical Accounting Policies and Estimates



Our management's discussion and analysis of our financial condition and results
of operations is based on our consolidated financial statements, which have been
prepared in accordance with generally accepted accounting principles in the
United States. The preparation of these consolidated financial statements
requires us to make estimates and assumptions that affect the amounts reported
in the financial statements and accompanying notes. We base our estimates on
historical experience, known facts and trends, and other market specific or
relevant assumptions we believe to be reasonable under the circumstances. On an
ongoing basis, we evaluate our estimates in light of changes in circumstance,
facts or experience. Actual results may differ from these estimates under
different assumptions or conditions.

While our significant accounting policies are described in more detail in the
notes to our consolidated financial statements appearing elsewhere in this
Annual Report on Form 10-K, we believe the following accounting policies to be
most critical to the judgments and estimates used in the preparation of our
consolidated financial statements.
                                       60

--------------------------------------------------------------------------------

Table of Contents

Revenue Recognition



We recognize revenue in accordance with Accounting Standards Codification, or
ASC, Topic 606, Revenue from Contracts with Customers, or ASC 606. Under ASC
606, an entity recognizes revenue when its customer obtains control of promised
goods or services, in an amount that reflects the consideration that the entity
expects to receive in exchange for those goods or services. In applying ASC 606,
we perform the following five steps: (i) identify the contract(s) with a
customer; (ii) identify the promises and performance obligations in the
contract; (iii) determine the transaction price; (iv) allocate the transaction
price to the performance obligations in the contract; and (v) recognize revenue
when (or as) we satisfy the performance obligations. At contract inception, once
the contract is determined to be within the scope of ASC 606, we assess the
goods or services promised within each contract, determine those that are
performance obligations and assess whether each promised good or service is
distinct. We then recognize as revenue the amount of the transaction price that
is allocated to the respective performance obligation when (or as) the
performance obligation is satisfied.

The terms of our license agreements include upfront and license fees, milestones
and other contingent payments for the achievement of defined certain clinical,
regulatory and sales-based milestone events, as well as royalties on sales of
commercialized products. Arrangements that include upfront payments may require
deferral of revenue recognition to a future period until obligations under such
arrangements are fulfilled. The event-based milestone payments represent
variable consideration, and we use the "most likely amount" method to estimate
this variable consideration. Given the high degree of uncertainty around the
occurrence of these events, we determined the milestone and other contingent
amounts to be fully constrained until the uncertainty associated with these
payments is resolved. Revenue will be recognized from sales-based royalty
payments when or as the sales occur. We will re-evaluate the transaction price
in each reporting period as uncertain events are resolved and other changes in
circumstances occur.

Accrued Research and Development Expenses



As part of the process of preparing our consolidated financial statements, we
are required to estimate our accrued research and development expenses as of
each balance sheet date. In accruing service fees, we estimate the time period
over which services will be performed and the level of effort to be expended in
each period. This process involves reviewing open contracts and purchase orders,
communicating with internal personnel to identify services that have been
performed on our behalf and estimating the level of service performed and the
associated cost incurred for the service when we have not yet been invoiced or
otherwise notified of the actual cost. We periodically confirm the accuracy of
our estimates with our service providers and make adjustments if necessary. The
majority of our service providers invoice us monthly in arrears for services
performed or when contractual milestones are met. The financial terms of
agreements with these service providers are subject to negotiation, vary from
contract-to-contract and may result in uneven payment flows. In circumstances
where amounts have been paid in excess of costs incurred, we record a prepaid
expense.

Although we do not expect our estimates to be materially different from amounts
actually incurred, if our estimates of the status and timing of services
performed differ from the actual status and timing of services performed, it
could result in us reporting amounts that are too high or too low in any
particular period. To date, there have been no material differences between our
estimates of such expenses and the amounts actually incurred.

Stock-based Compensation



We account for stock-based payments in accordance with ASC Topic
718, Compensation-Stock Compensation. This guidance requires all stock-based
payments to employees, including grants of employee stock options, restricted
stock awards and restricted stock units, to be recognized as expense in the
consolidated statements of operations and comprehensive income (loss) based on
their grant date fair values. For stock options granted to employees and to
members of our board of directors for their services on the board of directors,
we estimate the grant date fair value of each stock option using the
Black-Scholes option-pricing model. For restricted stock awards and restricted
stock units granted to employees, we estimate the grant date fair value of each
award using intrinsic value, which is based on the value of the underlying
common stock less any purchase price. For stock-based payments subject to
service-based vesting conditions, we recognize stock-based compensation expense
equal to the grant date fair value of stock-based payment on a straight-line
basis over the requisite service period.

                                       61

--------------------------------------------------------------------------------

Table of Contents



The Black­Scholes option pricing model requires the input of certain subjective
assumptions, including (i) the calculation of expected term of the stock-based
payment, (ii) the risk­free interest rate, (iii) the expected stock price
volatility and (iv) the expected dividend yield. We use the simplified method as
prescribed by SEC Staff Accounting Bulletin No. 107 to calculate the expected
term for stock options granted to employees as we do not have sufficient
historical exercise data to provide a reasonable basis upon which to estimate
the expected term. We determine the risk­free interest rate based on a treasury
instrument whose term is consistent with the expected term of the stock options.
Because there had been no public market for our common stock prior to our
initial public offering in 2017, there is a lack of historical and implied
volatility data. Accordingly, we base our estimates of expected volatility on a
combination of our own historical volatility and historical volatility of a
group of publicly-traded companies with characteristics similar to ours,
including stage of product development and therapeutic focus within the life
sciences industry. Historical volatility is calculated over a period of time
commensurate with the expected term of the stock-based payment. We use an
assumed dividend yield of zero as we have never paid dividends on our common
stock, nor do we expect to pay dividends on our common stock in the foreseeable
future.

We account for forfeitures of all stock-based payments when such forfeitures occur.



Income Taxes

Income taxes are recorded in accordance with ASC Topic 740, Income Taxes, which
provides for deferred taxes using an asset and liability approach. We recognize
deferred tax assets and liabilities for the expected future tax consequences of
events that have been included in the consolidated financial statements or tax
returns. Deferred tax assets and liabilities are determined based on the
difference between the financial statement and tax bases of assets and
liabilities using enacted tax rates in effect for the year in which the
differences are expected to reverse. A valuation allowance against deferred tax
assets is recorded if, based on the weight of the available evidence, it is more
likely than not that some or all of the deferred tax assets will not be
realized.

We account for uncertain tax positions using a more-likely-than-not threshold
for recognizing and resolving uncertain tax positions. The evaluation of
uncertain tax positions is based on factors, including, but not limited to,
changes in the law, the measurement of tax positions taken or expected to be
taken in tax returns, the effective settlement of matters subject to audit, new
audit activity and changes in facts or circumstances related to a tax position.

agreement related to the sale of GS-1811 in December 2022 and transfer of
certain patents and know-how related to licensed products to Gilead and (ii) the
Gilead License Agreement related to the achievement of a clinical development

$26.9 million of license and collaboration revenue under the Gilead License
Agreement related to the achievement of a $25.0 million clinical development and
regulatory milestone for FDA clearance of the IND for GS-1811 and $1.9 million
related to the completion of research and transition services.

Total research and development expenses   $     103,273            $ 88,979

$ 14,294

Research and development expenses increased by $14.3 million from $89.0 million for the year ended December 31, 2021 to $103.3 million for the year ended December 31, 2022. The increase in research and development expenses was primarily attributable to:

•$1.8 million of increased employee compensation costs primarily attributable to increased headcount;

•$10.8 million of increased external research and development costs associated with manufacturing and IND-enabling activities for our development programs;

•$2.9 million of increased lab consumables to support research activities; partially offset by,

•$0.7 million of decreased external clinical and regulatory costs primarily attributable to decreased development consulting required for our clinical trials; and

•$0.6 million in decreased depreciation expense.

General and Administrative Expenses

The following table summarizes our general and administrative expenses for the years ended December 31, 2022 and 2021:



                                                  Year Ended December 31,
(in thousands)                                       2022                2021        $ Change

Total general and administrative expenses   $      30,969             $ 

28,984 $ 1,985




General and administrative expenses increased by $2.0 million from $29.0 million
for the year ended December 31, 2021 to $31.0 million for the year ended
December 31, 2022. The increase in general and administrative expenses was
primarily attributable to increased consulting and other administrative costs
for the year ended December 31, 2022.

Other Income, net



Other income, net, increased by $1.3 million from $0.2 million for the year
ended December 31, 2021 to $1.5 million for the year ended December 31, 2022.
The increase in other income, net is attributable to increased rates of return
on our investments.

Liquidity and Capital Resources

Sources of Liquidity

We have funded our operations primarily through proceeds received from public offerings and private placements of our stock totaling $389.5 million and payments from license, collaboration or asset sale agreements totaling $467.0 million. As of December 31, 2022, we had cash, cash equivalents and investments of $189.5 million.



On November 4, 2021, we entered into a new Sales Agreement (the "2021 Sales
Agreement") with Cowen and Company, LLC, or Cowen, pursuant to which we may
offer and sell shares of our common stock with an aggregate offering price of up
to $75.0 million under an ATM offering program (the "2021 ATM Offering"). The
2021 Sales Agreement provides that Cowen

will be entitled to a sales commission equal to 3.0% of the gross sales price
per share of all shares sold under the 2021 ATM Offering. No sales were made
under the 2021 ATM Offering during the year ended December 31, 2022.

During the first quarter of 2021, we completed a follow-on public offering of
our common stock, selling an aggregate of 5,750,000 shares of common stock at a
public offering price of $11.25 per share for net proceeds of $60.6 million.

On December 17, 2019, we entered into a Sales Agreement with Cowen, pursuant to
which we could offer and sell shares of our common stock with an aggregate
offering price of up to $50.0 million under an "at the market" offering program
(the "2019 ATM Offering"). During the first quarter of 2021, we sold an
aggregate of 3,156,200 shares at an average price of $9.87 per share for net
proceeds of $30.2 million, which completed the sale of all available amounts
under the 2019 ATM Offering.

Funding Requirements

Due to our significant research and development expenditures, we have generated
substantial operating losses since inception. We have incurred an accumulated
deficit of $292.8 million through December 31, 2022. Whether or not we
successfully complete the Business Combination, we expect to incur additional
losses in the future as we conduct research and development activities. Based on
our research and development plans, we expect that our existing cash, cash
equivalents and investments of $189.5 million will enable us to fund our
operating expenses and capital expenditure requirements for at least 12 months
from the filing date of this Annual Report on Form 10-K. However, we have based
this estimate on assumptions that may prove to be incorrect, and we could
exhaust our capital resources sooner than we expect. The timing and amount of
our operating expenditures will depend largely on:

•whether or not we complete the Business Combination;



•whether we successfully license or dispose of the assets subject to the CVR
Agreement if the Business Combination is completed, or if it is not completed,
whether we are able to seek business development opportunities for both the
JTX-8064 and vopratelimab programs;

•the timing and progress of preclinical and clinical development activities;

•the cost to access, acquire or develop therapies to study in combination with our immunotherapies;

•completion of clinical trials;

•our ability to maintain our current research and development programs and enhancement of our Translational Science Platform;

•addition and retention of key research and development personnel;

•our efforts to enhance operational, financial and information management systems;

•the legal patent costs involved in prosecuting patent applications and enforcing patent claims and other intellectual property claims;

•the costs and ongoing investments to in-license or acquire additional technologies, including the in-license of intellectual property related to our potential product candidates; and

•the terms and timing of any future collaboration, license or other arrangement, including the terms and timing of any option and milestone payments thereunder.



A change in the outcome of any of these or other variables with respect to the
development of any of our product candidates could significantly change the
costs and timing associated with the development of that product candidate.
Furthermore, our operating plans may change in the future, and we may need
additional funds to meet operational needs and capital requirements associated
with such operating plans or we may conduct additional reductions in force.

In addition to the variables described above, if and when any of our product
candidates successfully complete development, we expect to incur substantial
additional costs associated with regulatory filings, marketing approval,
post-marketing requirements, maintaining our intellectual property rights, and
regulatory protection, in addition to other costs. We cannot reasonably estimate
these costs at this time.

Until such time, if ever, as we can generate substantial product revenue, we
expect to finance our cash needs through a combination of equity or debt
financings, collaborations, licensing arrangements and strategic alliances. We
currently do not have a credit facility or committed sources of capital. To the
extent that we raise additional capital through the future sale of equity or
debt, the ownership interests of our stockholders will be diluted, and the terms
of these securities may include liquidation or other preferences that adversely
affect the rights of our existing common stockholders. If we raise additional
funds through the issuance of debt securities, these securities could contain
covenants that would restrict our operations. We

may require additional capital beyond our currently anticipated amounts.
Additional capital may not be available on reasonable terms, or at all. If we
raise additional funds through collaboration arrangements in the future, we may
have to relinquish valuable rights to our technologies, future revenue streams
or product candidates, or grant licenses on terms that may not be favorable to
us. If we are unable to raise additional funds through equity or debt financings
when needed, we may be required to delay, limit, reduce, or terminate
development or future commercialization efforts, or grant rights to develop and
market product candidates that we would otherwise prefer to develop and market
ourselves.
