CELL THERAPEUTICS, INC.
CTI is a pharmaceutical research and development company that focuses on the
discovery, development and commercialization of small molecule drugs relevant
to the treatment of cancer. CTI's initial business strategy is to build a
diversified, vertically integrated portfolio of oncology products targeting
major unmet needs in the treatment of patients with cancer. CTI's principal
executive offices are located at 201 Elliott Avenue West, Seattle, WA 98119.
CTI's telephone number is (206) 282-7100.
On January 13, 2000, we acquired the drug arsenic trioxide upon our
acquisition of PolaRx, a single product company that owned the rights to
arsenic trioxide.In connection with the acquisition, we issued 2,000,000 shares
of our common stock at signing and may issue an additional 3,000,000 shares to
PolaRx shareholders upon the earlier of approval of a New Drug Application by
the FDA for arsenic trioxide or five years from the acquisition date. Two
additional payouts tied to annualized sales thresholds of $10 million and $20
million may be payable in tranches of $4 million and $5 million at the then
fair market value of our stock, at the time such thresholds are achieved. The
acquisition agreement requires shareholder approval for 2,000,000 of the
additional shares and payments to be made in our stock if the annualized sales
thresholds are achieved. For annual sales of arsenic trioxide in excess of $40
million, PolaRx shareholders will receive a 2% royalty on net sales payable at
the then fair market value of our common stock or, in certain circumstances,
cash.
RISK FACTORS
You should carefully consider the following factors and other information
included or incorporated by reference in this prospectus before deciding to
invest in the shares.
If we continue to incur net losses, we may not achieve or maintain
profitability.
We were incorporated in 1991 and have incurred a net operating loss every
year. As of December 31, 1999, we had an accumulated deficit of approximately
$158.4 million. We have not generated any product revenue from sales to date.
We may never generate revenue nor become profitable, even if we are able to
commercialize any products. We will need to conduct significant research,
development, testing and regulatory compliance activities that, together with
projected general and administrative expenses, we expect will result in
substantial increasing operating losses for at least the next several years.
Even if we do achieve profitability, we may not be able to sustain or increase
profitability on a quarterly or annual basis.
If we do not successfully develop products, we may be unable to generate any
revenue.
Our leading drug candidates, arsenic trioxide, PG-TXL and Apra, are
currently in clinical trials. These clinical trials of the drug candidates
involve the testing of potential therapeutic agents, or effective treatments,
in humans in three phases to determine the safety and efficacy of the drug
candidates necessary for an approved drug. Many drugs in human clinical trials
fail to demonstrate the desired safety and efficacy characteristics. Even if
our drugs progress successfully through initial human testing, they may fail in
later stages of development. A number of companies in the pharmaceutical
industry, including CTI, have suffered significant setbacks in advanced
clinical trials, even after reporting promising results in earlier trials. For
example, in our first phase III human trial for lisofylline, completed in March
1998, we failed to meet our two primary endpoints, or goals, even though we met
our endpoints in two earlier phase II trials for lisofylline. As a result,
1
<PAGE>
we are no longer developing lisofylline as a potential product. In addition,
data obtained from clinical trials are susceptible to varying interpretations.
Government regulators and our collaborators may not agree with our
interpretation of our future clinical trial results. The clinical trials of
arsenic trioxide, PG-TXL and Apra or any of our future drug candidates may not
be successful.
Many of our drug candidates are still in research and preclinical
development, which means that they have not yet been tested on humans. We will
need to commit significant time and resources to develop these and additional
product candidates. We are dependent on the successful completion of clinical
trials and obtaining regulatory approval in order to generate revenues. The
failure to generate such revenues may preclude us from continuing our research
and development of these and other product candidates.
Even if our drug candidates are successful in clinical trials, we may not be
able to successfully commercialize them.
Since our inception in 1991, we have dedicated substantially all of our
resources to the research and development of our technologies and related
compounds. All of our compounds currently are in research or development, and
none has been submitted for marketing approval. Our other compounds may not
enter human clinical trials on a timely basis, if at all, and we may not
develop any product candidates suitable for commercialization. Prior to
commercialization, each product candidate will require significant additional
research, development and preclinical testing and extensive clinical
investigation before submission of any regulatory application for marketing
approval. Potential products that appear to be promising at early stages of
development may not reach the market for a number of reasons. Potential
products may:
. be found ineffective or cause harmful side effects during preclinical
testing or clinical trials
. fail to receive necessary regulatory approvals
. be difficult to manufacture on a large scale
. be uneconomical to produce
. fail to achieve market acceptance
. be precluded from commercialization by proprietary rights of third
parties
Our product development efforts or our collaborative partners' efforts may
not be successfully completed and we may not obtain required regulatory
approvals. Any products, if introduced, may not be successfully marketed nor
achieve customer acceptance.
Because we based several of our drug candidates on unproven novel technologies,
we may never develop them into commercial products.
We base many of our product candidates upon novel delivery technologies
which we are using to discover and develop drugs for the treatment of cancer.
This technology has not been proven. Furthermore, preclinical results in animal
studies may not predict outcome in human clinical trials. Our product
candidates may not be proven safe or effective. If this technology does not
work, our drug candidates may not develop into commercial products.
We may not complete our clinical trials in the time expected which could delay
or prevent the commercialization of our products.
Although for planning purposes we forecast the commencement and completion
of clinical trials, the actual timing of these events can vary dramatically due
to factors such as delays, scheduling conflicts with participating clinicians
and clinical institutions and the rate of patient accruals. Clinical trials
involving our product candidates may not commence nor be completed as
forecasted. We have limited experience in conducting clinical trials. In
certain circumstances we rely on academic institutions or clinical research
2
<PAGE>
organizations to conduct, supervise or monitor some or all aspects of clinical
trials involving our products. In addition, certain clinical trials for our
products will be conducted by government-sponsored agencies and consequently
will be dependent on governmental participation and funding. We will have less
control over the timing and other aspects of these clinical trials than if we
conducted them entirely on our own. These trials may not commence or be
completed as we expect. They may not be conducted successfully. Failure to
commence or complete, or delays in, any of our planned clinical trials could
delay or prevent the commercialization of our products and harm our business.
If we fail to adequately protect our intellectual property, our competitive
position could be harmed.
Development and protection of our intellectual property are critical to our
business. If we do not adequately protect our intellectual property,
competitors may be able to practice our technologies. Our success depends in
part on our ability to:
. obtain patent protection for our products or processes both in the United
States and other countries
. protect trade secrets
. prevent others from infringing on our proprietary rights
In particular we believe that linking our polymers to existing drugs may
yield patentable subject matter. We do not believe that our polymer-drug
conjugates will infringe any third-party patents covering the underlying drug.
However, we may not receive a patent for our polymer conjugates and we may be
challenged by the holder of a patent covering the underlying drug.
The patent position of biopharmaceutical firms generally is highly uncertain
and involves complex legal and factual questions. The U.S. Patent and Trademark
Office has not established a consistent policy regarding the breadth of claims
that it will allow in biotech patents. If it allows broad claims, the number
and cost of patent interference proceedings in the U.S. and the risk of
infringement litigation may increase. If it allows narrow claims, the risk of
infringement may decrease, but the value of our rights under our patents,
licenses and patent applications may also decrease.
Patent applications in which we have rights may never issue as patents and
the claims of any issued patents may not afford meaningful protection for our
technologies or products. In addition, patents issued to us or our licensors
may be challenged and subsequently narrowed, invalidated or circumvented.
Litigation, interference proceedings or other governmental proceedings that we
may become involved in with respect to our proprietary technologies or the
proprietary technology of others could result in substantial cost to us. Patent
litigation is widespread in the biotechnology industry, and any patent
litigation could harm our business. Costly litigation might be necessary to
protect our orphan drug designations or patent position or to determine the
scope and validity of third-party proprietary rights, and we may not have the
required resources to pursue such litigation or to protect our patent rights.
An adverse outcome in litigation with respect to the validity of any of our
patents could subject us to significant liabilities to third parties, require
disputed rights to be licensed from third parties or require us to cease using
a product or technology.
We also rely upon trade secrets, proprietary know-how and continuing
technological innovation to remain competitive. Third parties may independently
develop such know-how or otherwise obtain access to our technology. While we
require our employees, consultants and corporate partners with access to
proprietary information to enter into confidentiality agreements, these
agreements may not be honored.
If any of our license agreements for intellectual property underlying arsenic
trioxide, PG-TXL or any other product are terminated, we may lose our rights to
develop or market that product.
Patents issued to third parties may cover our products as ultimately
developed. We may need to acquire licenses to these patents or challenge the
validity of these patents. We may not be able to license any patent
3
<PAGE>
rights on acceptable terms or successfully challenge such patents. The need to
do so will depend on the scope and validity of these patents and ultimately on
the final design or formulation of the products and services that we develop.
We have licensed intellectual property, including patent applications from
Memorial Sloan Kettering Cancer Institute, Samuel Waxman Cancer Research
Foundation, Beijing Medical University and others, including the intellectual
property underlying our most advanced product candidate, arsenic trioxide. We
have also in-licensed the intellectual property relating to our polymer drug
delivery technology, including PG-TXL. Some of our product development programs
depend on our ability to maintain rights under these licenses. Each licensor
has the power to terminate its agreement with us if we fail to meet our
obligations under that license. We may not be able to meet our obligations
under these licenses. If we default under any of these license agreements, we
may lose our right to market and sell any products based on the licensed
technology.
Our products could infringe on the intellectual property rights of others,
which may cause us to engage in costly litigation and, if we are not
successful, could cause us to pay substantial damages and prohibit us from
selling our products.
Although we attempt to monitor the patent filings of our competitors in an
effort to guide the design and development of our products to avoid
infringement, third parties may challenge the patents that have been issued or
licensed to us. We may have to pay substantial damages, possibly including
treble damages, for past infringement if it is ultimately determined that our
products infringe a third party's patents. Further, we may be prohibited from
selling our products before we obtain a license, which, if available at all,
may require us to pay substantial royalties. Even if infringement claims
against us are without merit, defending a lawsuit takes significant time, may
be expensive and may divert management attention from other business concerns.
Our lack of operating experience may cause us difficulty in managing our
growth.
We have no experience in selling pharmaceutical products and only limited
experience in negotiating, establishing and maintaining strategic
relationships, in manufacturing or procuring products in commercial quantities
and conducting other later-stage phases of the regulatory approval process.
Furthermore, we only recently acquired our first leading drug candidate,
arsenic trioxide, in January from PolaRx. We have no experience with respect to
the launch of a commercial product. Our ability to manage our growth, if any,
will require us to improve and expand our management and our operational and
financial systems and controls, particularly with respect to arsenic trioxide.
If our management is unable to manage growth effectively, our business and
financial condition would be materially harmed. In addition, if rapid growth
occurs, it may strain our operational, managerial and financial resources.
If we fail to keep pace with rapid technological change in the biotechnology
and pharmaceutical industries, our products could become obsolete.
Biotechnology and related pharmaceutical technology have undergone and are
subject to rapid and significant change. We expect that the technologies
associated with biotechnology research and development will continue to develop
rapidly. Our future will depend in large part on our ability to maintain a
competitive position with respect to these technologies. Any compounds,
products or processes that we develop may become obsolete before we recover any
expenses incurred in connection with developing these products.
We face direct and intense competition from our rivals in the biotechnology and
pharmaceutical industries and we may not compete successfully against them.
The biotechnology and pharmaceutical industries are intensely competitive.
We have numerous competitors in the United States and elsewhere. Our
competitors include major, multinational pharmaceutical and chemical companies,
specialized biotechnology firms and universities and other research
institutions. Many of these competitors have greater financial and other
resources, larger research and development staffs and
4
<PAGE>
more effective marketing and manufacturing organizations, than we do. In
addition, academic and government institutions have become increasingly aware
of the commercial value of their research findings. These institutions are now
more likely to enter into exclusive licensing agreements with commercial
enterprises, including our competitors, to market commercial products.
Our competitors may succeed in developing or licensing technologies and
drugs that are more effective or less costly than any we are developing. Our
competitors may succeed in obtaining FDA or other regulatory approvals for drug
candidates before we do. In particular, we face direct competition from many
companies focusing on delivery technologies. Drugs resulting from our research
and development efforts, if approved for sale, may not compete successfully
with our competitors' existing products or products under development.
If we fail to raise substantial additional capital, we will have to curtail or
cease operations.
We expect that our existing capital resources and the interest earned
thereon will enable us to maintain our current and planned operations until
mid-2001. Beyond that time, if our capital resources are insufficient to meet
future capital requirements, we will have to raise additional funds to continue
the development of our technologies and complete the commercialization of
products, if any, resulting from our technologies. We will require substantial
funds to: (1) continue our research and development programs, (2) in-license or
acquire additional technologies, and (3) conduct preclinical studies and
clinical trials. We may need to raise additional capital to fund our operations
repeatedly. We may raise such capital through public or private equity
financings, partnerships, debt financings, bank borrowings, or other sources.
Our capital requirements will depend upon numerous factors, including the
following:
. the establishment of additional collaborations
. the development of competing technologies or products
. changing market conditions
. the cost of protecting our intellectual property rights
. the purchase of capital equipment
. the progress of our drug discovery and development programs, the progress
of our collaborations and receipt of any option/license, milestone and
royalty payment resulting from those collaborations
. in-licensing and acquisition opportunities
Additional funding may not be available on favorable terms or at all. If
adequate funds are not otherwise available, we may curtail operations
significantly. To obtain additional funding, we may need to enter into
arrangements that require us to relinquish rights to certain technologies, drug
candidates, products and/or potential markets. To the extent that additional
capital is raised through the sale of equity, or securities convertible into
equity, you may experience dilution of your proportionate ownership of the
company.
Our stock price is extremely volatile, which may affect our ability to raise
capital in the future.
The market price for securities of biopharmaceutical and biotechnology
companies, including that of ours, historically has been highly volatile, and
the market from time to time has experienced significant price and volume
fluctuations that are unrelated to the operating performance of such companies.
For example, in the last twelve months, our stock price has ranged from a low
of $1.3125 to a high of $52.00. Fluctuations in the trading price or liquidity
of our common stock may adversely affect our ability to raise capital through
future equity financings.
Factors that may have a significant impact on the market price and
marketability of our common stock include:
. announcements of technological innovations or new commercial therapeutic
products by us, our collaborative partners or our present or potential
competitors
5
<PAGE>
. our quarterly operating results
. announcements by us or others of results of preclinical testing and
clinical trials
. developments or disputes concerning patent or other proprietary rights
. developments in our relationships with collaborative partners
. acquisitions
. litigation
. adverse legislation, including changes in governmental regulation and the
status of our regulatory approvals or applications
. third-party reimbursement policies
. changes in securities analysts' recommendations
. changes in health care policies and practices
. economic and other external factors
. general market conditions
In the past, following periods of volatility in the market price of a
company's securities, securities class action litigation has often been
instituted. If a securities class action suit is filed against us, we would
incur substantial legal fees and our management's attention and resources would
be diverted from operating our business in order to respond to the litigation.
There are a substantial number of unregistered shares of our common stock
which, when registered for resale, could result in a decrease in our stock
price or impair our ability to raise funds in future equity offerings.
The sale, or availability for sale, of substantial amounts of our common
stock in the public market could materially decrease the market price of our
common stock and could impair our ability to raise additional capital.
We have filed a resale registration statement for 4,624,277 shares of our
common stock underlying our Series D preferred stock and warrants issued in
November 1999. We also intend to file a resale registration statement covering
5,000,000 shares issued or that may be issued in connection with the
acquisition of PolaRx.
Any sales by existing shareholders or holders of options or warrants may
have an adverse effect on our ability to raise capital and may adversely affect
the market price of the common stock.
Our dependence on third-party manufacturers means that we may not have
sufficient control over the manufacture of our products.
We currently do not have internal facilities for the manufacture of any of
our products for clinical or commercial production. We will need to develop
additional manufacturing resources, enter into collaborative arrangements with
other parties which have established manufacturing capabilities or elect to
have other third parties manufacture our products on a contract basis. For
example, we are a party to an agreement with Aerojet to furnish Apra bulk drug
substance for future clinical studies. We are dependent on such collaborators
or third parties to supply us in a timely way with products manufactured in
compliance with standards imposed by the FDA and foreign regulators. The
manufacturing facilities of contract manufacturers may not comply with
applicable manufacturing regulations of the FDA nor meet our requirements for
quality, quantity or timeliness.
6
<PAGE>
We may face difficulties in achieving acceptance of our products in the market
due to our lack of sales and marketing capabilities and other factors.
We have no direct experience in marketing, sales or distribution. The
creation of infrastructure to commercialize pharmaceutical products is an
expensive and time-consuming process. In the event that arsenic trioxide
achieves regulatory approval, we will need to build a sales and marketing force
to market the product. Should we have to market and sell our other products
directly, we would need to further develop a marketing and sales force with
sufficient technical expertise and distribution capability. We may be unable to
develop the necessary marketing and sales capabilities and we may fail to gain
market acceptance for our products.
If we lose our key personnel or are unable to attract and retain additional
personnel, we may be unable to pursue collaborations or develop our own
products.
We are highly dependent on Dr. James A. Bianco, Chief Executive Officer, and
Dr. Jack Singer, Executive Vice President, Research Program Chairman. The loss
of these principal members of our scientific or management staff, or failure to
attract or retain other key scientific personnel employees, could prevent us
from pursuing collaborations or developing our products and core technologies.
Recruiting and retaining qualified scientific personnel to perform research and
development work are critical to our success. There is intense competition for
qualified scientists and managerial personnel from numerous pharmaceutical and
biotechnology companies, as well as from academic and government organizations,
research institutions and other entities. In addition, we rely on consultants
and advisors, including our scientific and clinical advisors, to assist us in
formulating our research and development strategy. All of our consultants and
advisors are employed by other employers or are self-employed, and have
commitments to or consulting or advisory contracts with other entities that may
limit their availability to us.
If we fail to obtain regulatory approvals, we will be unable to commercialize
our products.
We do not have a drug product approved for sale in the U.S. or any foreign
market. We must obtain approval from the FDA in order to sell our drug products
in the U.S. and from foreign regulatory authorities in order to sell our drug
products in other countries. We recently submitted our first new drug
application for approval to the FDA for arsenic trioxide. Once an application
is submitted, the FDA could reject the application or require us to conduct
additional clinical or other studies as part of the regulatory review process.
Delays in obtaining or failure to obtain FDA approvals would prevent or delay
the commercialization of our drug products, which could prevent, defer or
decrease our receipt of revenues.
The regulatory review and approval process is lengthy, expensive and
uncertain. Extensive preclinical and clinical data and supporting information
must be submitted to the FDA for each indication for each drug in order to
secure FDA approval. We have limited experience in obtaining such approvals,
and cannot be certain when we will receive these regulatory approvals, if ever.
In addition to initial regulatory approval, our drug products will be
subject to extensive and rigorous ongoing domestic and foreign government
regulation, as we discuss in more detail in "Business--Government Regulation."
Any approvals, once obtained, may be withdrawn if compliance with regulatory
requirements is not maintained or safety problems are identified. Failure to
comply with these requirements may subject us to stringent penalties.
Because there is a risk of product liability associated with our products, we
face potential difficulties in obtaining insurance.
Our business exposes us to potential product liability risks inherent in the
testing, manufacturing and marketing of human pharmaceutical products, and we
may not be able to avoid significant product liability exposure. Except for
insurance covering product use in our clinical trials, we do not currently have
any product liability insurance, and it is possible that we will not be able to
obtain or maintain such insurance on acceptable
7
<PAGE>
terms or that any insurance obtained will provide adequate coverage against
potential liabilities. Our inability to obtain sufficient insurance coverage at
an acceptable cost or otherwise to protect against potential product liability
claims could prevent or limit the commercialization of any products we develop.
A successful product liability claim in excess of our insurance coverage could
exceed our net worth.
Uncertainty regarding third-party reimbursement and health care cost
containment initiatives may limit our returns.
The ongoing efforts of governmental and third-party payors to contain or
reduce the cost of health care will affect our ability to commercialize our
products successfully. Governmental and other third-party payors increasingly
are attempting to contain health care costs by:
. challenging the prices charged for health care products and services
. limiting both coverage and the amount of reimbursement for new
therapeutic products
. denying or limiting coverage for products that are approved by the FDA
but are considered experimental or investigational by third-party payors
. refusing in some cases to provide coverage when an approved product is
used for disease indications in a way that has not received FDA marketing
approval
In addition, the trend toward managed health care in the United States, the
growth of organizations such as health maintenance organizations, and
legislative proposals to reform healthcare and government insurance programs
could significantly influence the purchase of healthcare services and products,
resulting in lower prices and reducing demand for our products.
Even if we succeed in bringing any of our proposed products to the market,
they may not be considered cost-effective and third-party reimbursement might
not be available or sufficient. If adequate third-party coverage is not
available, we may not be able to maintain price levels sufficient to realize an
appropriate return on our investment in research and product development. In
addition, legislation and regulations affecting the pricing of pharmaceuticals
may change in ways adverse to us before or after any of our proposed products
are approved for marketing. While we cannot predict whether any such
legislative or regulatory proposals will be adopted, the adoption of such
proposals could make it difficult or impossible to sell our products.
Although we believe that we adequately prepared for Year 2000 issues, it is
possible that Year 2000 problems of other companies could impact our business.
Although we have not experienced any Year 2000 problems, the systems of
other companies on which we rely may still remain vulnerable to the Year 2000
issue. Potential impacts could include, but are not limited to, future revenue
delays due to delayed research, development, clinical trials or agency
approvals. We presently believe the Year 2000 issue will not pose significant
operational problems for our computer systems or third-party relationships. We
believe that the Year 2000 issues have been effectively avoided, but we have
developed for each critical activity a contingency plan to allow operations to
continue even if significant issues are experienced.
Since we use hazardous materials in our business, we may be subject to claims
relating to improper handling, storage or disposal of these materials.
Our research and development activities involve the controlled use of
hazardous materials, chemicals and various radioactive compounds. We are
subject to federal, state and local laws and regulations governing the use,
manufacture, storage, handling and disposal of such materials and certain waste
products. Although we believe that our safety procedures for handling and
disposing of such materials comply with the standards prescribed by state and
federal regulations, the risk of accidental contamination or injury from these
materials cannot be eliminated completely. In the event of such an accident, we
could be held liable for any damages that
8
<PAGE>
result and any such liability not covered by insurance could exceed our
resources. Compliance with environmental laws and regulations may be expensive,
and current or future environmental regulations may impair our research,
development or productions efforts.
We may not be able to conduct animal testing in the future which could harm our
research and development activities.
Certain of our research and development activities involve animal testing.
Such activities have been the subject of controversy and adverse publicity.
Animal rights groups and other organizations and individuals have attempted to
stop animal testing activities by pressing for legislation and regulation in
these areas. To the extent the activities of these groups are successful, our
business could be materially harmed by delaying or interrupting our research
and development activities.
Because our charter documents contain certain anti-takeover provisions and we
have a rights plan, it may be more difficult for a third party to acquire us,
and the rights of some shareholders could be adversely affected.
Our Restated Articles of Incorporation and Bylaws contain provisions that
may make it more difficult for a third party to acquire or make a bid for us.
These provisions could limit the price that certain investors might be willing
to pay in the future for shares of our common stock. In addition, shares of our
preferred stock may be issued in the future without further shareholder
approval and upon such terms and conditions and having such rights, privileges
and preferences, as the board of directors may determine. The rights of the
holders of common stock will be subject to, and may be adversely affected by,
the rights of any holders of preferred stock that may be issued in the future.
The issuance of preferred stock, while providing desirable flexibility in
connection with possible acquisitions and other corporate purposes, could have
the effect of making it more difficult for a third party to acquire, or of
discouraging a third party from acquiring, a majority of our outstanding voting
stock. We have no present plans to issue any shares of preferred stock. In
addition, we have adopted a shareholder rights plan that, along with certain
provisions of our Restated Articles of Incorporation, may have the effect of
discouraging certain transactions involving a change of control of the company.

PLAN OF DISTRIBUTION
CTI is registering all 6,198,087 shares on behalf of certain selling
shareholders. All of the shares either originally were issued by us or will be
issued upon the conversion of Series D preferred stock or upon exercise of
warrants to acquire shares of our common stock. CTI will receive no proceeds
from this offering. The selling shareholders named in the table above or
pledgees, donees, transferees or other successors-in-interest selling shares
received from a named selling shareholder as a gift, partnership distribution
or other non-sale-related transfer after the date of this prospectus may sell
the shares from time to time. The selling shareholders will act independently
of CTI in making decisions with respect to the timing, manner and size of each
sale. The sales may be made on one or more exchanges or in the over-the-counter
market or otherwise, at prices and at terms then prevailing or at prices
related to the then current market price, or in negotiated transactions. The
selling shareholders may effect such transactions by selling the shares to or
through broker-dealers. The shares may be sold by one or more of, or a
combination of, the following:
. a block trade in which the broker-dealer so engaged will attempt to sell
the shares as agent but may position and resell a portion of the block as
principal to facilitate the transaction,
. purchases by a broker-dealer as principal and resale by such broker-
dealer for its account pursuant to this prospectus,
. an exchange distribution in accordance with the rules of such exchange,
. ordinary brokerage transactions and transactions in which the broker
solicits purchasers, and
. in privately negotiated transactions.
To the extent required, this prospectus may be amended or supplemented from
time to time to describe a specific plan of distribution. In effecting sales,
broker-dealers engaged by the selling shareholders may arrange for other
broker-dealers to participate in the resales.
The selling shareholders may enter into hedging transactions with broker-
dealers in connection with distributions of the shares or otherwise. In such
transactions, broker-dealers may engage in short sales of the shares in the
course of hedging the positions they assume with selling shareholders. The
selling shareholders also may sell shares short and redeliver the shares to
close out such short positions. The selling shareholders may enter into option
or other transactions with broker-dealers which require the delivery to the
broker-dealer of the shares. The broker-dealer may then resell or otherwise
transfer such shares pursuant to this prospectus. The selling shareholders also
may loan or pledge the shares to a broker-dealer. The broker-dealer may sell
the shares so loaned, or upon a default the broker-dealer may sell the pledged
shares pursuant to this prospectus.
Broker-dealers or agents may receive compensation in the form of
commissions, discounts or concessions from selling shareholders. Broker-dealers
or agents may also receive compensation from the purchasers of the shares for
whom they act as agents or to whom they sell as principals, or both.
Compensation as to a particular broker-dealer might be in excess of customary
commissions and will be in amounts to be negotiated in connection with the
sale. Broker-dealers or agents and any other participating broker-dealers or
the selling shareholders may be deemed to be "underwriters" within the meaning
of Section 2(11) of the Securities Act in connection with sales of the shares.
Accordingly, any such commission, discount or concession received by them and
any profit on the resale of the shares purchased by them may be deemed to be
underwriting discounts or commissions under the Securities Act. Because selling
shareholders may be deemed to be "underwriters" within the meaning of Section
2(11) of the Securities Act, the selling shareholders will be subject to the
prospectus delivery requirements of the Securities Act. In addition, any
securities covered by this prospectus which qualify for sale pursuant to Rule
144 promulgated under the Securities Act may be sold under Rule 144 rather than
pursuant to this prospectus. The selling shareholders have advised CTI that
they have not entered into any agreements, understandings or arrangements with
any underwriters or broker-dealers regarding the sale of their securities.
There is no underwriter or coordinating broker acting in connection with the
proposed sale of shares by selling shareholders.
12
<PAGE>
The shares will be sold only through registered or licensed brokers or
dealers if required under applicable state securities laws. In addition, in
certain states the shares may not be sold unless they have been registered or
qualified for sale in the applicable state or an exemption from the
registration or qualification requirement is available and is complied with.
Under applicable rules and regulations under the Exchange Act, any person
engaged in the distribution of the shares may not simultaneously engage in
market making activities with respect to our common stock for a period of two
business days prior to the commencement of such distribution. In addition, each
selling shareholder will be subject to applicable provisions of the Exchange
Act and the associated rules and regulations under the Exchange Act, including
Regulation M, which provisions may limit the timing of purchases and sales of
shares of our common stock by the selling shareholders. CTI will make copies of
this prospectus available to the selling shareholders and has informed them of
the need for delivery of copies of this prospectus to purchasers at or prior to
the time of any sale of the shares.
CTI will file a supplement to this prospectus, if required, pursuant to Rule
424(b) under the Securities Act upon being notified by a selling shareholder
that any material arrangement has been entered into with a broker-dealer for
the sale of shares through a block trade, special offering, exchange
distribution or secondary distribution or a purchase by a broker or dealer.
Such supplement will disclose:
. the name of each such selling shareholder and of the participating
broker-dealer(s),
. the number of shares involved,
. the price at which such shares were sold,
. the commissions paid or discounts or concessions allowed to such broker-
dealer(s), where applicable,
. that such broker-dealer(s) did not conduct any investigation to verify
the information set out or incorporated by reference in this prospectus,
and
. other facts material to the transaction.
In addition, upon being notified by a selling shareholder that a donee or
pledgee intends to sell more than 500 shares, CTI will file a supplement to
this prospectus.
CTI will bear all costs, expenses and fees in connection with the
registration of the shares. The selling shareholders will bear all commissions
and discounts, if any, attributable to the sales of the shares. The selling
shareholders may agree to indemnify any broker-dealer or agent that
participates in transactions involving sales of the shares against certain
liabilities, including liabilities arising under the Securities Act. The
selling shareholders have agreed to indemnify certain persons, including
broker-dealers and agents, against certain liabilities in connection with the
offering of the shares, including liabilities arising under the Securities Act.

The validity of the securities offered hereby will be passed upon for CTI by
Wilson Sonsini Goodrich & Rosati, San Francisco, California.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS
Sections 23B.08.500 through 23B.08.600 of the Washington Business
Corporation Act (the "WBCA") authorize a court to award, or a corporation's
board of directors to grant, indemnification to directors and officers on terms
sufficiently broad to permit indemnification under certain circumstances for
liabilities arising under the Securities Act of 1933, as amended (the
"Securities Act"). Article IX of CTI's Restated Bylaws provides for
indemnification of CTI's directors, officers, employees and agents to the
maximum extent permitted by Washington law. The directors and officers of CTI
also may be indemnified against liability they may incur for serving in such
capacity pursuant to a liability insurance policy maintained by CTI for such
purpose.
Section 23B.08.320 of the WBCA authorizes a corporation to limit a
director's liability to the corporation or its shareholders for monetary
damages for acts or omissions as a director, except in certain circumstances
involving intentional misconduct, knowing violations of law or illegal
corporate losses or distributions, or any transaction from which the director
personally receives a benefit in money, property or services to which the
director is not legally entitled. Article VI of the Registrant's Restated
Articles of Incorporation (Exhibit 4.1 hereto) contains provisions
implementing, to the fullest extent permitted by Washington law, such
limitations on a director's liability to the Registrant and its shareholders.
CTI has entered into an indemnification agreement with each of its executive
officers and directors in which CTI agrees to hold harmless and indemnify the
officer or director to the fullest extent permitted by Washington law. CTI
agrees to indemnify the officer or director against any and all losses, claims,
damages, liabilities or expenses incurred in connection with any actual,
pending or threatened action, suit, claim or proceeding, whether civil,
criminal, administrative or investigative and whether formal or informal, in
which the officer or director is, was or becomes involved by reason of the fact
that the officer or director is or was a director, officer, employee, trustee
or agent of the Registrant or any related company, partnership or enterprise,
including service with respect to an employee benefit plan, whether the basis
of such proceeding is alleged action (or inaction) by the officer or director
in an official capacity and any action, suit, claim or proceeding instructed by
or at the direction of the officer or director unless such action, suit, claim
or proceeding is or was authorized by CTI's Board of Directors. No indemnity
pursuant to the indemnification agreements shall be provided by CTI on account
of any suit in which a final, unappealable judgment is rendered against the
officer or director for an accounting of profits made from the purchase or sale
by the officer or director of securities of CTI in violation of the provisions
of Section 16(b) of the Securities Exchange Act of 1934, or for damages that
have been paid directly to the officer or director by an insurance carrier
under a policy of directors' and officers' liability insurance maintained by
CTI.
II-1
<PAGE>
CTI has entered into Registration Rights Agreements with the selling
holders. Such agreements provide for indemnification by such selling holders of
the Company and its officers and directors, and by the Company of such selling
holders, for certain liabilities arising under the Securities Act or otherwise.

ITEM 17. UNDERTAKINGS
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; (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; and (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.
(2) That, for the purpose of determining any liability under the
Securities Act, 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.
Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions or otherwise, the registrant
has been advised that in the opinion of the SEC such indemnification is against
public policy as expressed in the Securities Act and therefore is
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 and will be governed
by the final adjudication of such issue.
The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act, and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the Exchange Act, 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.
