                                 RISK FACTORS
 
  Prospective investors should consider carefully the factors set forth below
together with the other information contained in this Prospectus before making
a decision to purchase the Common Stock.
 
RISKS ASSOCIATED WITH DEVELOPMENT STRATEGY
 
  The Company's strategy is to become the leading provider of a broad range of
cancer management information, including diagnostic and prognostic analyses.
To date, the Company's business has consisted primarily of providing patient-
specific diagnostic and prognostic information based on the testing of tissue
specimens and the customized analysis of test results. The Company's strategy
includes incorporating evolving technologies into cancer management,
establishing a database focused on outcomes designed to optimize cancer
management, establishing strategic partnerships and joint ventures, developing
managed care relationships and expanding into new geographic areas. Some of
the services proposed to be offered by the Company, particularly the outcomes-
oriented enhancements to its database, have not been fully developed and will
require significant additional development prior to commercialization, which
further development and commercialization may never occur. The Company may
encounter problems and delays related to establishing strategic partnerships
and joint ventures, the continued development and expansion of its database or
the expansion of sales and marketing, and the failure to address such problems
and delays successfully could have a material adverse effect on the Company's
business and prospects. Moreover, the Company intends to pursue strategic
acquisitions if such acquisitions further aspects of the Company's strategy
outlined above. To the extent that the Company's strategy is dependent upon
acquisitions, there can be no assurance that suitable acquisition candidates
will be identified by the Company in the future, that, if required, suitable
financing for any such acquisitions can be obtained by the Company, or that
any such acquisitions will occur. If the Company successfully completes a
strategic acquisition or acquisitions, the financial performance of the
Company will be subject to various risks associated with the acquisition of
businesses, including the financial impact of expenses associated with the
integration of such businesses. There can be no assurance that such
acquisitions will not have an adverse effect on the business operations or
profitability of the Company.
 
ACCESS TO NEW TECHNOLOGIES; LACK OF PROPRIETARY TECHNOLOGY
 
  To date, the Company has not engaged in the development or patenting of its
own technologies for use in the analytical services it provides, and access to
new technologies developed by third parties has been an important element in
the Company's current business as well as the Company's long-term strategy. If
the Company's access to critical technologies were substantially diminished,
the Company's business could be adversely affected.
 
  In addition, the Company currently relies on certain technologies which are
not patentable or proprietary and are therefore available to the Company's
competitors. Furthermore, the Company relies on certain proprietary trade
secrets and know-how, which are not patentable. Although the Company has taken
steps to protect its unpatented trade secrets and know-how, in part through
the use of confidentiality agreements with its employees, there can be no
assurance that these agreements will not be breached, that the Company would
have adequate remedies for any breach or that the Company's trade secrets will
not otherwise become known or be independently developed or discovered by
competitors. If the Company's trade secrets become known or are independently
developed or discovered by competitors, it could have a material adverse
effect on the Company.
 
RISKS ASSOCIATED WITH ESTABLISHING JOINT VENTURES
 
  The Company plans to pursue strategic partnerships and joint ventures with
oncology networks, hospital groups, managed care companies and pharmaceutical
companies, primarily for the purposes of expanding IMPATH's diagnostic and
prognostic database, participating in the
 
                                       3
<PAGE>
 
development of new cancer therapies and demonstrating to the medical community
the importance of the services provided by IMPATH. There can be no assurance
that the Company will be able to negotiate acceptable partnership or joint
venture arrangements or that such arrangements will be successful or that
potential partners will not pursue alternative means of developing treatments
for cancer. No assurance can be given that the Company's joint venture
partners will be able to obtain regulatory approval for any new treatments,
that any such new treatments if so approved will be commercialized
successfully or that the Company will realize any revenues in connection with
such arrangements. Although the Company believes that other parties to joint
ventures generally have an economic motivation to perform their contractual
responsibilities, their devotion of resources to such activities will not be
within the control of the Company. Depending on the Company's obligations in
such joint ventures, the termination or cancellation of such arrangements
could also adversely affect the Company's financial condition and results of
operations.
 
REIMBURSEMENT
 
  The Company typically bills third party payors, such as private insurance
plans, managed care plans and governmental programs (i.e., Medicare) as well
as hospitals, for its services. These third party payors are increasingly
negotiating prices with the goal of lowering reimbursement rates. The Company
expects these pricing pressures to cause reduced pricing on average for tests
in future periods.
 
  In 1994, 1995 and 1996, approximately 22%, 24% and 25%, respectively, of the
Company's net revenues for diagnostic and prognostic services were derived
from analyses performed for beneficiaries under the Medicare program. The
Company accepts Medicare reimbursement as payment in full for its services,
subject to applicable copayments and deductibles. Medicare may retroactively
audit and review its payments to the Company, and may determine that certain
payments for services must be repaid. Significant disapprovals of payment for
any of the Company's services by various carriers, including Medicare and
private insurance and managed care, reductions or delays in the establishment
of reimbursement rates, and carrier limitations on the coverage of the
Company's services could have a material adverse effect on the Company's
future revenues. The services furnished by the Company are characterized for
the purposes of the Medicare program as physician pathology services.
 
  Any future changes in government and other third-party payor reimbursement
which may come about as a result of enactment of health care reform or of
deficit-reduction legislation also likely will continue the downward pressure
on prices, and make the market for cancer analytical services more
competitive. Because of the uncertainties about the nature, content and timing
of any reform initiative, the Company currently is unable to predict the
ultimate impact thereof on the Company.
 
COMPETITION
 
  The Company provides services in a segment of the health care industry that
is highly fragmented and extremely competitive. The Company's actual or
potential competitors include large university or teaching hospitals; large
clinical laboratories that have substantially greater financial, marketing,
logistical and laboratory resources than the Company; special purpose clinical
laboratories that have limited test offerings and a highly focused product and
marketing strategy; and the Company's customers or potential customers who may
choose to perform services similar to those performed by the Company. It is
anticipated that competition will continue to increase due to such factors as
the perceived potential for commercial applications of biotechnology and the
continued availability of investment capital and government funding for
cancer-related research. There can be no assurance that competition in
existing or new markets will not have a material adverse effect on the
Company's operating results. Changes in the regulatory environment in which
the Company operates could also affect the basis for competition and could
thereby have a material adverse effect on the Company's operating results.
 
                                       4
<PAGE>
 
DEPENDENCE ON KEY MANAGEMENT AND QUALIFIED PERSONNEL
 
  The Company is dependent upon the efforts of its senior management and
medical professionals. The loss of the services of one or more members of its
senior management or one or more medical professionals could impede the
achievement of the Company's development objectives. In addition, the
Company's growth strategy will require additional skill and expertise, the
addition of new management personnel and the development of additional
expertise by existing management personnel. The loss of, or failure to
recruit, scientific, technical and managerial personnel could have a material
adverse effect on the Company.
 
REGULATORY MATTERS
 
  As a provider of health care related services, the Company is subject to
extensive and frequently changing federal, state and local regulations
governing licensure, billing, financial relationships, referrals, conduct of
operations, purchase of existing businesses, cost-containment, direct
employment of licensed professionals by business corporations and other
aspects of the Company's business relationships. Federal and state
certification and licensure programs establish standards for the day-to-day
operation of facilities such as the Company's. Compliance with such standards
is verified by periodic inspections and requires participation in proficiency
testing programs. No assurances can be given that the Company's facilities
will pass all future inspections conducted to ensure compliance with federal
or any other applicable licensure or certification laws.
 
  Existing federal laws governing Medicare, as well as some state laws,
regulate certain aspects of the relationship between health care providers,
including the Company, and their referral sources, including physicians,
hospitals and other facilities. The Social Security Act, and the anti-kickback
and self-referral rules thereunder, prohibit providers and others from
soliciting, offering, receiving or paying, directly or indirectly, any
remuneration in return for either making a referral for a Medicare-covered
service or item or ordering any such covered service or item and prohibit
physicians, subject to certain exceptions, from making such referrals to
certain entities in which they have an investment interest or with which they
have a compensation arrangement. Violation of these prohibitions is punishable
by disallowance of submitted claims, civil monetary and criminal penalties and
exclusion from the Medicare and other federally financed programs.
 
  The laws of many states prohibit physicians from sharing professional fees
with non-physicians and prohibit non-physician entities, such as the Company,
from practicing medicine (including pathology) and from employing physicians
to practice medicine (including pathology). The Company believes its current
and planned activities do not constitute fee-splitting or violate any
prohibition against the corporate practice of medicine. However, there can be
no assurance that future interpretations of such laws will not require
structural or organizational modifications of the Company's existing business.
 
RISK OF LIABILITY; ADEQUACY OF INSURANCE COVERAGE
 
  The marketing and sale of health care services could expose the Company to
the risk of certain types of litigation, including medical malpractice.
Damages assessed in connection with, and the costs of defending, any legal
action could be substantial. Although the Company is presently covered by
general liability insurance in the amount of $6,000,000 per occurrence and
$7,000,000 in the aggregate and has obtained professional liability insurance
in the amount of $1,000,000 per occurrence and $3,000,000 in the aggregate for
the Company's Medical Directors and other individuals who practice medicine,
there can be no assurance that insurance coverage will provide sufficient
funds to satisfy any judgments which, in the future, may be entered against
the Company or that liability insurance in such amounts will be available or
affordable in the future. In addition, there can be no assurance that all of
the activities encompassed within the Company's business are
 
                                       5
<PAGE>
 
covered under the Company's policies. The Company's liability insurance covers
claims relating to the handling and disposal of medical specimens and
infectious and hazardous waste, except in the event of malfeasance or fraud by
the Company. Furthermore, there can be no assurance that the Company will have
other resources sufficient to satisfy any liability or litigation expenses
that may result from any uninsured or underinsured claims. Moreover, although
the Company maintains personal property and business interruption insurance
and has taken what it believes to be adequate safeguards, the catastrophic
loss of the Company's tissue library could have a material adverse effect on
the continued development of its database in a manner which would not be fully
compensated by insurance.
 
CONTROL BY SELLING STOCKHOLDERS; ANTI-TAKEOVER MEASURES
   
  The Selling Stockholders in the aggregate beneficially own approximately
39.5% of the Company's outstanding shares of Common Stock. See "Selling
Stockholders." As a result, these stockholders, acting together, would be able
to control many matters requiring approval by the stockholders of the Company,
including the election of directors. The Company's certificate of
incorporation authorizes the Company to issue Preferred Stock, the terms of
which may be fixed by the Board of Directors. No shares of Preferred Stock are
currently outstanding. Such provisions could have the effect of delaying,
deferring or preventing a change of control of the Company.     
 
POSSIBLE VOLATILITY OF STOCK PRICE
 
  There has been a history of significant volatility in the market prices for
shares of companies engaged in the health care and biotechnology fields, and
it may be expected that the market price of the shares of Common Stock offered
hereby may be highly volatile. Factors such as fluctuations in the Company's
quarterly revenues and operating results, announcements of technological
innovations or new analytical services by the Company and its competitors, and
changes in third party reimbursement and governmental regulation may have a
significant effect on the market price of the Common Stock.
 
DIVIDENDS
 
  The Company does not currently pay dividends on its Common Stock and does
not anticipate paying any dividends in the foreseeable future. It is
anticipated that the terms of any future debt financings may restrict the
payment of dividends.

  The following table sets forth certain information regarding beneficial
ownership of the Common Stock as of April 1, 1997, and after giving effect to

indicated, the persons named in the table have sole voting and investment

                             PLAN OF DISTRIBUTION
 
  The shares offered hereby may be offered and sold from time to time by the
Selling Stockholders, or by pledgees, donees, transferees or other successors
in interest. Such offers and sales may be made from time to time through the
Nasdaq National Market or otherwise, at prices and on terms then prevailing or
at prices related to the then-current market price, or in negotiated
transactions. The methods by which the shares may be sold may include, but are
not limited to, the following: (a) a block trade in which the broker or 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; (b)
purchases by a broker or dealer as principal and resale by such broker or
dealer for its account; (c) an exchange distribution in accordance with the
rules of such exchange; (d) ordinary brokerage transactions and transactions
in which the broker solicits purchasers; (e) privately negotiated
transactions; (f) short sales; and (g) a combination of any such methods of
sale. In effecting sales, brokers or dealers engaged by the Selling
Stockholders may receive commissions or discounts from the Selling
Stockholders or from the purchasers in amounts to be negotiated immediately
prior to the sale. The Selling Stockholders may also sell shares in accordance
with Rule 144 under the Securities Act.
 
  The Selling Stockholders and any brokers and dealers participating in such
sales may be deemed to be "underwriters" within the meaning of the Securities
Act. There can be no assurance that the Selling Stockholders will sell any or
all of the shares offered hereby.
 
  The Company is bearing all of the costs relating to the registration of the
shares, except commissions, discounts or other fees payable to a broker,
dealer, underwriter, agent or market maker in connection with the sale of any
of the shares, all of which will be borne by the Selling Stockholders. The
Company will not receive any of the proceeds from the Offering, except that it
will receive $148,852 upon the exercise of the warrants.
 
  Pursuant to the registration rights granted to the Selling Stockholders, the
Company has agreed to indemnify the Selling Stockholders and any person who
controls a Selling Stockholder against certain liabilities and expenses
arising out of or based upon the information set forth or incorporated by
reference in this Prospectus, and the Registration Statement of which this
Prospectus is a part, including liabilities under the Securities Act. Any
commissions paid or any discounts or concessions allowed to any broker,
dealer, underwriter, agent or market maker and, if any such broker, dealer,
underwriter, agent or market maker purchases any of the shares as principal,
any profits received on the resale of such shares, may be deemed to be
underwriting commissions or discounts under the Securities Act.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  Article Five, Section 7 of the Certificate of Incorporation (the
"Certificate") provides that, to the fullest extent permitted by Section 145
of the Delaware Law, or any comparable successor law, as the same may be
amended and supplemented from time to time, the Company (i) may indemnify all
persons whom it shall have power to indemnify under the Delaware Law from and
against any and all of the expenses, liabilities or other matters referred to
in or covered thereby, (ii) shall indemnify each such person if he is or is
threatened to be made a party to an action, suit or proceeding by reason of
the fact that he is or was a director, officer, employee or agent of the
Company or because he was serving the Company or any other legal entity in any
capacity at the request of the Company while a director, officer, employee or
agent of the Company and (iii) shall pay the expenses of such a current or
former director, officer, employee or agent incurred in connection with any
such action, suit or proceeding in advance of the final disposition of such
action, suit or proceeding. The Certificate further provides that the
indemnification and advancement of expenses provided for therein shall not be
deemed exclusive of any other rights to which those entitled to
indemnification or advancement of expenses may be entitled under any by-law,
agreement, contract or vote of stockholders or disinterested directors or
pursuant to the direction (however embodied) of any court of competent
jurisdiction or otherwise, both as to action in his official capacity and as
to action in another capacity while holding such office, and shall continue as
to a person who has ceased to be a director, officer, employee or agent and
shall inure to the benefit of the heirs, executors and administrators of such
a person.
 
  The Company has entered into indemnification agreements with all directors
and executive officers of the Company providing that the directors and
executive officers will be indemnified to the fullest possible extent
permitted by Delaware law against all expenses (including attorneys' fees),
judgments, fines, penalties, taxes and settlement amounts paid or incurred by
them in any action or proceeding, including any action by or in the right of
the Company or any of its subsidiaries or affiliates, on account of their
service as directors, officers, employees, fiduciaries or agents of the
Company or any of its subsidiaries or affiliates, and their service at the
request of the Company or any of its subsidiaries or affiliates as directors,
officers, employees, fiduciaries or agents of another corporation,
partnership, joint venture, trust, employee benefit plan or other enterprise.
 
  The Company maintains liability insurance for its officers and directors,
insuring them against certain losses arising from claims or charges made
against them while acting in their capacities as officers or directors of the
Company.
 
                                     II-1

<PAGE>
 
  Article Five, Section 6 of the Certificate provides that a director of the
Company shall not be personally liable to the Company or its stockholders for
monetary damages for breach of fiduciary duty as a director, except for
liability (i) for any breach of the director's duty of loyalty to the Company
or its stockholders, (ii) for acts or omissions not in good faith or which
involve intentional misconduct or a knowing violation of law, (iii) for the
unlawful payment of dividends or unlawful stock purchases under Section 174 of
the Delaware Law, or (iv) for any transaction from which the director derived
any improper personal benefit. If the Delaware Law is amended to eliminate
further or limit the personal liability of directors, then the liability of a
director of the Company shall be eliminated or limited to the fullest extent
permitted by the Delaware Law, as so amended. Any repeal or modification of
such provision of the Certificate by the stockholders of the Company shall be
prospective only and shall not adversely affect any right or protection of a
director of the Company existing at the time of such repeal or modification.
 
  While the Certificate provides directors with protection from awards for
monetary damages for breaches of their duty of care, it does not eliminate
such duty. Accordingly, the Certificate will have no effect on the
availability of equitable remedies such as an injunction or rescission based
on a director's breach of his or her duty of care. The provisions of the
Certificate described above apply to an officer of the Company only if he or
she is a director of the Company and is acting in his or her capacity as
director, and do not apply to officers of the Company who are not directors.
 
 
ITEM 16. EXHIBITS.
 
  The Exhibits required to be filed as part of this Registration Statement are
listed in the attached Index to Exhibits.
 
 
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 of 1933;
 
                                     II-2

<PAGE>
 
    individually or in the aggregate, represent a fundamental change in the
    information set forth in this Registration Statement; and
 
      (iii) To include any material information with respect to the plan of
    distribution not previously disclosed in this Registration Statement or
    any material change to such information in this Registration Statement.
 
    (2) That, for the purpose of determining any liability under the
  Securities Act of 1933, each such post-effective amendment shall be deemed
  to be a new registration statement relating to the securities offered
  therein, and the offering of such securities at that time shall be deemed
  to be the initial bona fide offering thereof.
 
    (3) To remove from registration by means of a post-effective amendment
  any of the securities being registered which remain unsold at the
  termination of the offering.

  The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's Annual Report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 that is incorporated by reference in this
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.
 
  Insofar as indemnification for liabilities arising under the Securities Act
of 1933 (the "Act") may be permitted to directors, officers and controlling
persons of the registrant pursuant to the provisions of its Certificate of
Incorporation or By-laws or the laws of the State of Delaware, or otherwise,
the registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the 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 Act, the information
omitted from the form of prospectus filed as part of this Registration
Statement in reliance upon Rule 430A and contained in a form of prospectus
filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the
Act shall be deemed to be part of this Registration Statement as of the time
it was declared effective.
 
  For the purpose of determining any liability under the Act, each post-
effective amendment that contains a form of prospectus 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.
