                                   THE COMPANY

         The following summary is qualified in its entirety by reference to the
more detailed information and the financial statements and the related notes
appearing elsewhere in this Prospectus or incorporated herein by reference.
Unless the context otherwise requires, all references herein to the Company
refer to Biofield Corp. and its subsidiaries. Each prospective investor is urged
to read this Prospectus in its entirety. Investment in the securities offered
hereby involves a high degree of risk. See "Risk Factors" starting on page 7.

         Biofield Corp. is a medical technology company that has developed an
innovative system for detecting breast cancer through the skin in a noninvasive
and objective procedure. The Company's breast cancer diagnostic device, the
Biofield Diagnostic System (formerly referred to as the ALEXA 1000 System),
employs unique, single-use sensors and a measurement device to detect and
analyze changes in cellular electrical charge distributions associated with the
development of epithelial cancers, such as breast cancer. The Biofield
Diagnostic System is intended to provide physicians and patients with immediate
and objective information concerning the probability that a lesion, which has
been identified by breast cancer screening or with other diagnostic modalities,
is malignant or benign. Such information, together with other available clinical
information, can be used by the physician to make further treatment decisions,
including whether to proceed to surgical biopsy. The Company believes that the
Biofield Diagnostic System could improve early diagnosis, reduce diagnostic
uncertainty and decrease the number of diagnostic procedures, including surgical
biopsies, performed on suspicious lesions.

         The Company's principal offices are located at 1225 Northmeadow
Parkway, Suite 120, Roswell, Georgia 30076, and its telephone number is (770)
740-8180.

                               RECENT DEVELOPMENTS

PRIVATE PLACEMENT

         On December 17, 1997, the Company consummated a private placement (the
"1997 Private Placement") of 2,867,670 shares of Common Stock, yielding
aggregate gross proceeds to the Company of $9,033,160. The 1997 Private
Placement was made pursuant to the exemption from the registration requirements
of the Securities Act provided by Section 4(2) thereof and Regulation D
thereunder.

         The Company intends to use the net proceeds, estimated to be
approximately $8,400,000, of the 1997 Private Placement for funding clinical
trials, research and development, manufacturing, European sales and marketing
and general corporate purposes.

         Concurrent with the closing of the 1997 Private Placement, the Company
issued an aggregate of 643,639 shares of Common Stock in exchange for
outstanding warrants to purchase an aggregate of 1,574,930 shares of Common
Stock (the "Warrant Exchange"). Such warrants were issued in connection with the
Company's 1995 private placement of securities units. In order to participate in
the Warrant Exchange, warrant holders were required to invest in the 1997
Private Placement.

         After giving effect to the 1997 Private Placement and the Warrant
Exchange, at December 17, 1997 there were outstanding 10,029,609 shares of
Common Stock, warrants to purchase an aggregate of 396,762 shares of Common
Stock with a weighted average exercise price of $9.83 per share, and options to
purchase an aggregate of 1,983,969 shares of Common Stock with a weighted
average exercise price of $5.60 per share. This registration statement was
required to be filed pursuant to a registration rights agreement entered into
between the Company and the investors in the 1997 Private Placement, so that the
resale of the shares of Common Stock purchased by such investors would be
registered under the Securities Act. In addition, certain holders of Common
Stock, and warrants to purchase shares of Common Stock, have exercised other
registration rights to have shares of Common Stock included in the registration
statement of which this Prospectus forms a part.

MANAGEMENT

         Robert M. Johnson was appointed the Company's Chief Operating Officer
in August 1997. Prior to joining the Company, from 1994 to August 1997, Mr.
Johnson served as Senior Vice President, Business Development at Healthdyne

                                  RISK FACTORS

         Except for the historical information contained herein, this Prospectus
contains "forward-looking statements" within the meaning of the Private
Securities Litigation Reform Act of 1995, such as statements of the Company's
plans, objectives, expectations and intentions. All such forward-looking
statements involve known and unknown risks, uncertainties and other factors that
could cause the Company's actual results to be materially different from any
results expressed or implied by such forward-looking statements. All cautionary
statements made in this Prospectus should be read as being applicable to all
related forward-looking statements wherever they appear in this Prospectus. See
"Special Note Regarding Forward-Looking Statements." The following risk factors
should be considered carefully in addition to the other information in this
Prospectus before purchasing the shares of Common Stock offered hereby.

UNCERTAINTY OF FDA APPROVAL FOR THE BIOFIELD DIAGNOSTIC SYSTEM

         On December 30, 1996, the Company submitted its premarket approval
application ("PMA") to the U.S. Food and Drug Administration ("FDA") for the
Biofield Diagnostic System. On February 27, 1997, the FDA informed the Company
that its PMA had not been accepted for filing and requested that the Company
address deficiencies in the PMA for further consideration of such PMA.
Specifically, the FDA has not accepted the findings from the Company's U.S.
Multi-center Study as submitted in the PMA. The FDA stated that it had concerns
about the study design and, in particular, the development and selection of the
algorithm used on the supporting data set. The FDA advised the Company that it
must first select a final algorithm and then test it with an independent data
set. Further, the FDA stated that the design of the clinical trial must provide
data that supports the indications for use of the Biofield Diagnostic System
which should include the impact on patient management.

      The initial PMA for the Biofield Diagnostic System was based principally
upon the results of the Company's U.S. Multi-center Study, which results have
not been accepted by the FDA based upon its initial review of the PMA. The PMA
as submitted to the FDA included data from clinical trials on over 1,200 women
tested at six medical institutions under the direction of physicians involved in
breast cancer diagnosis and treatment. Subsequent to the FDA's initial review,
the Company has been in discussions with the FDA regarding the design and
protocol for an additional clinical trial in support of an amendment to or
resubmission of the PMA. Discussions with the FDA aimed at establishing the
design and protocol for the additional clinical trial are ongoing. The clinical
trial protocol may have a significant impact on the time required to complete
the clinical trial. Following these discussions with the FDA, the Company will
evaluate its options and finalize its plans for proceeding. The Company
currently anticipates starting the enrollment phase of an additional clinical
trial in support of an amendment or resubmission of the PMA during the first
half of 1998. The timing of patient enrollment in the additional clinical trial
will depend upon development of a clinical trial design and protocol acceptable
to the Company and the FDA, and the Company's receipt of approval to conduct the
additional clinical trial from the Institutional Review Boards of the proposed
study sites. The enrollment phase of the clinical trial is expected to take
several months or longer, followed by data analysis. The time necessary to
complete the additional clinical trial will depend upon numerous factors,
including the number of patients to be included in the study, the criteria for
inclusion of patients in the study, the ability to recruit and enroll patients
in the study and the time required to analyze the clinical results. The PMA, if
and when accepted for filing by the FDA, will be reviewed under the FDA's
Expedited Review policy.





                                        7

<PAGE>   8



       Conducting additional clinical trials will require the expenditure of
substantial additional funds. Furthermore, there can be no assurance that
results obtained in any additional trials will be consistent with the results
obtained in the U.S. Multi-center Study or that any such results, or the amended
or resubmitted PMA, will be accepted by the FDA. There can be no assurance that
the FDA or other regulatory approvals for the Biofield Diagnostic System will be
granted on a timely basis, or at all. Failure to obtain FDA approval to market
the Biofield Diagnostic System would have a material adverse effect on the
Company's business, financial condition, cash flows and results of operations.
See "Risk Factors -- Government Regulation; No Assurance of Regulatory
Approvals."

LIMITED OPERATING HISTORY; CONTINUING OPERATING LOSSES

      The Company has a limited history of operations. Since its inception in
October 1987, the Company has engaged principally in the development of the
Biofield Diagnostic System, which has not been approved for sale in the United
States. Consequently, the Company has little experience in manufacturing,
marketing and selling its products. The Company currently has no source of
operating revenue and has incurred net operating losses since its inception. At
September 30, 1997, the Company had an accumulated deficit of $42,888,641. Such
losses have resulted principally from costs incurred in research and development
and clinical trials and from general and administrative costs associated with
the Company's operations. The Company expects operating losses to increase for
at least the next several years due principally to the anticipated expenses
associated with the pre-market approval process for the Biofield Diagnostic
System, the proposed commercialization of the Biofield Diagnostic System,
development of, and clinical trials for, the proposed Biofield screening system
and other research and development activities.

UNCERTAINTIES AS TO FUTURE PROFITABILITY

      The Company's ability to achieve profitability will depend in part on its
ability to obtain regulatory approvals for the Biofield Diagnostic System and
any other proposed products, and to develop the capacity to manufacture and
market any approved products either by itself or in collaboration with others.
There can be no assurance if or when the Company will receive required
regulatory approvals for the development and commercial manufacturing and
marketing of the Biofield Diagnostic System or any other proposed products, or
achieve profitability. Accordingly, the extent of future losses and the time
required to achieve profitability are highly uncertain.

EARLY STAGE OF PRODUCT DEVELOPMENT

      The Company's proposed products, other than the Biofield Diagnostic
System, are at an early stage of development and the Biofield Diagnostic System
must be approved by the FDA before it can be commercially marketed in the United
States. There can be no assurance that any of the Company's proposed products
will be found to be safe and effective, meet applicable regulatory standards or
receive necessary regulatory clearance, or if safe and effective, can be
developed into commercial products, manufactured on a large scale or be
economical to market. Nor can there be any assurance that the Company's proposed
products will achieve or sustain market acceptance. In the event necessary
regulatory approvals are obtained for the Biofield Diagnostic System, there can
be no assurance that the Company will be successful in establishing commercial
operations, including gaining market acceptance of the Biofield Diagnostic
System and implementing commercial-scale manufacturing and sales and marketing
programs. There is, therefore, substantial risk that the Company's product
development and commercialization efforts will not prove to be successful.

<PAGE>   9




DEPENDENCE ON A SINGLE PRODUCT

      Although the Company is in the process of developing additional products
based on its core technology, including an enhancement of the Biofield
Diagnostic System for use on asymptomatic women, none of such applications is
expected to result in a commercial product for at least several years, if at
all. Consequently, pending its approval for commercial distribution in the
United States, the Biofield Diagnostic System would account for substantially
all of the Company's revenues for the foreseeable future. Failure to gain
regulatory approvals or market acceptance for the Biofield Diagnostic System
would have a material adverse effect on the Company's business, financial
condition, cash flows and results of operations.

DEPENDENCE ON MARKET ACCEPTANCE

      There can be no assurance that physicians or the medical community in
general will accept and utilize the Biofield Diagnostic System or any other
products developed by the Company. The extent that, and rate at which, the
Biofield Diagnostic System achieves market acceptance and penetration will
depend on many variables including, but not limited to, the establishment and
demonstration in the medical community of the clinical safety, efficacy and
cost-effectiveness of the Biofield Diagnostic System, the advantages of the
Biofield Diagnostic System over existing technology and cancer detection methods
(including x-ray mammography, ultrasound or high frequency ultrasound, MRI,
stereotactic needle biopsy and thermography, diaphonography and
transillumational devices), third-party reimbursement practices and the
Company's manufacturing, quality control, marketing and sales efforts. There can
be no assurance that the medical community and third-party payors will accept
the Company's unique technology. Similar risks will confront the proposed
Biofield screening system and any other products developed by the Company in the
future. Failure of the Company's products to gain market acceptance would have a
material adverse effect on the Company's business, financial condition, cash
flows and results of operations.

LIMITED MARKETING AND SALES EXPERIENCE

      The Company has limited internal marketing and sales resources and
personnel. In order to market the Biofield Diagnostic System or any other
products it may develop, the Company will have to develop a marketing and sales
force with technical expertise and distribution capabilities. There can be no
assurance that the Company will be able to establish sales and distribution
capabilities or that the Company will be successful in gaining market acceptance
for any products it may develop. There can be no assurance that the Company will
be able to recruit and retain skilled sales, marketing, service or support
personnel, that agreements with distributors will be available on terms
commercially reasonable to the Company, or at all, or that the Company's
marketing and sales efforts will be successful. Failure to successfully
establish a marketing and sales organization, whether directly or through third
parties, would have a material adverse effect on the Company's business,
financial condition, cash flows and results of operations. The Company intends
to pursue one or more distribution arrangements in the United States, Europe and
Asia with strategic marketing partners who have established marketing
capabilities. There can be no assurance that the Company, either on its own or
through arrangements with others, will be able to enter into such arrangements
on acceptable terms, if at all. To the extent that the Company arranges with
third parties to market its products, the success of such products may depend on
the efforts of such third parties. There can be no assurance that any of the
Company's proposed marketing schedules or plans can or will be met.

LIMITED MANUFACTURING HISTORY

      The Company does not have any manufacturing or production facilities or
experience in manufacturing or contracting for the manufacturing of its proposed
products in the volumes that will be necessary for the Company to achieve
significant commercial sales in the event it obtains regulatory approval to
market its products. While the Company does not currently manufacture any of its
products, it may do so in the future. The Company has no experience in the
manufacture of medical products for clinical trials or commercial purposes.
Should the Company manufacture its products, the Company's manufacturing
facilities would be subject to the full range of current Good Manufacturing
Practices ("GMP") regulations and similar risks of delay or difficulty in
manufacturing and the Company would require substantial additional capital to
establish such manufacturing facilities. In addition, there can be no assurance
that the Company would be able to manufacture any such products successfully or
cost-effectively.

DEPENDENCE ON THIRD PARTIES

      The Company has used certain third parties to manufacture and deliver the
components of the Biofield Diagnostic System and the proposed Biofield screening
system used in clinical studies, and intends to continue to use third parties to
manufacture and deliver such products and any other products which the Company
may seek to develop. Such third parties must adhere to the GMP regulations
enforced by the FDA through its facilities inspection program and such
third-parties' facilities must pass a plant inspection before the FDA will grant
premarket approval of the Company's products. There can be no assurance that the
third-party manufacturers on which the Company depends for the manufacture of
the Biofield Diagnostic System will be in compliance with the GMP regulations at
the time of the pre-approval inspection or will maintain such compliance. Such
failure could significantly delay FDA approval of the PMA application for the
Biofield Diagnostic System, and such delay would have a material adverse effect
on the Company's business, financial condition, cash flows and results of
operations.

      The qualification of additional or replacement suppliers for certain
components of the Biofield Diagnostic System or services is a lengthy process.
For certain services and components the Company currently relies on single
suppliers. If the Company encounters delays or difficulties with its third-party
suppliers in producing, packaging or distributing components of the Biofield
Diagnostic System, market introduction and subsequent sales would be adversely
affected. The Company also may have to rely on alternative sources of supply. In
such case, there can be no assurance that the Company will be able to enter into
alternative supply arrangements at commercially acceptable rates, if at all. If
the Company is unable to obtain or retain qualified third-party manufacturers on
commercially acceptable terms, it may not be able to commercialize its products
as planned. The Company's dependence upon third parties for the manufacture of
its products may adversely affect the Company's profit margins and its ability
to develop and deliver its products on a timely and competitive basis.

COMPETITION

         The medical device industry generally, and the cancer diagnostic and
screening segments in particular, are characterized by rapidly evolving
technology and intense competition. Other companies in the medical device
industry are marketing products that compete with the Biofield Diagnostic System
and may be developing, or could in the future attempt to develop, additional
products that are competitive with the Biofield Diagnostic System. Many of the
Company's competitors have substantially greater capital




                                       10

<PAGE>   11



resources and name recognition than the Company. Many of these companies also
have substantially greater expertise than the Company in research and
development, manufacturing and marketing and obtaining regulatory approvals.
There can be no assurance that the Company's competitors will not succeed in
developing or marketing technologies and products that are more effective than
those developed or marketed by the Company or that would render the Company's
technology and products obsolete or noncompetitive. Additionally, there can be
no assurance that the Company will be able to compete against such competitors
and potential competitors in terms of manufacturing, marketing and sales.
Although the Company believes that its products may offer certain technological
advantages over its competitors' currently-marketed products, earlier entrants
in the market for a diagnostic application often obtain and maintain significant
market share relative to later entrants. Physicians using imaging equipment such
as x-ray mammography equipment, ultrasound or high frequency ultrasound systems,
MRI systems, stereotactic needle biopsy and thermography, diaphonography,
electrical impedance and transilluminational devices may not use the Biofield
Diagnostic System or any other products that the Company may develop. Currently,
mammography is employed widely and the Company's ability to sell the Biofield
Diagnostic System to medical facilities will, in part, be dependent on the
Company's ability to demonstrate the clinical utility of the Biofield Diagnostic
System as an adjunct to mammography and physical examination and its advantages
over other available diagnostic tests.

RISK OF TECHNOLOGICAL OBSOLESCENCE

         Methods for the detection of cancer are subject to rapid technological
innovation and there can be no assurance that technological changes will not
render the Company's proposed products obsolete. There can be no assurance that
the development of new types of diagnostic medical equipment or technology will
not have a material adverse effect on the marketability of the Biofield
Diagnostic System or any other products developed by the Company. Commercial
availability of such products could render the Company's products obsolete,
which would have a material adverse effect on the Company's business, financial
condition, cash flows and results of operations.

POTENTIAL RELIANCE ON INTERNATIONAL SALES

         The Company intends to commence commercial sales of the Biofield
Diagnostic System in Europe prior to commencing commercial sales in the United
States, where sales cannot occur unless and until the Company receives premarket
approval from the FDA. Thus, until the Company receives approval from the FDA to
market the Biofield Diagnostic System, as to which there can be no assurance,
the Company's revenues, if any, will be derived from international sales. A
significant portion of the Company's revenues, therefore, may be subject to the
risks associated with international sales, including economic or political
instability, shipping delays, fluctuations in foreign currency exchange rates,
foreign regulatory requirements and various trade restrictions, all of which
could have a significant impact on the Company's ability to deliver products on
a competitive and timely basis. Future imposition of, or significant increases
in the level of, customs duties, export quotas or other trade restrictions could
have a material adverse effect on the Company's business, financial condition,
cash flows and results of operations. The regulation of medical devices,
particularly in Europe, continues to develop and there can be no assurance that
new laws or regulations will not have an adverse effect on the Company.






                                       11

<PAGE>   12



GOVERNMENT REGULATION; NO ASSURANCE OF REGULATORY APPROVALS

         The manufacture and sale of medical devices, including the Biofield
Diagnostic System, the proposed Biofield screening system, and any other
products that may be developed by the Company are subject to extensive
regulation by numerous governmental authorities in the United States,
principally the FDA and corresponding state agencies, and in other countries. In
the United States, the Company's products are regulated as medical devices and
are subject to the FDA's premarket clearance or approval requirements. Securing
FDA clearances and approvals may require the submission of extensive clinical
data and supporting information to the FDA. To obtain FDA approval of an
application for premarket approval, the premarket approval application must
demonstrate that the subject device has clinical utility, meaning that the
device has a beneficial therapeutic effect, or that as a diagnostic tool, it
provides information that measurably contributes to a diagnosis of a disease or
condition. The results of the Company's U.S. Multi-center Study have not been
accepted by the FDA based upon its initial review of the PMA. The Company,
therefore, plans to submit data from additional clinical testing in connection
with any amendment to or resubmission of the PMA. The timing of patient
enrollment in the additional clinical trial will depend upon development of a
clinical trial design and protocol acceptable to the Company and the FDA, and
the Company's receipt of approval to conduct the additional clinical trial from
the Institutional Review Boards of the proposed study sites. As a result of this
additional testing, the Company anticipates further delays, which may be
significant, in the approval process for the Biofield Diagnostic System. The
process of obtaining FDA and other required regulatory approvals is lengthy,
expensive and uncertain and frequently requires from one to several years from
the date of the FDA submission, if premarket approval is obtained at all.
Following the filing of an amendment to or resubmission of the PMA for the
Biofield Diagnostic System, the FDA may require more information or
clarification of information already provided as part of the PMA. During the
review period, an advisory panel will likely be convened by the FDA to review
and evaluate the PMA and provide recommendations to the FDA as to whether the
PMA should be approved. Although the FDA has granted Expedited Review status to
the Biofield Diagnostic System, there can be no assurance that such status will
result in timely approval of the Biofield Diagnostic System, if at all.
Furthermore, an approval, if granted, may include significant limitations on the
indicated uses for which the Biofield Diagnostic System may be marketed. Failure
to obtain FDA approval to market the Biofield Diagnostic System would have a
material adverse effect on the Company's business, financial condition, cash
flows and results of operations.

         Sales of medical devices outside of the United States are subject to
international regulatory requirements that vary from country to country. The
time required to obtain approval for sale internationally may be longer or
shorter than that required for FDA approval and the requirements may differ. In
addition, in order to sell its products within the European Economic Area
following June 14, 1998, companies are required to achieve compliance with the
requirements of the Medical Devices Directive and affix a "CE" marking on their
products to attest such compliance. The Company has not obtained such
certifications, and there can be no assurance that it will be able to do so in a
timely manner, or at all.

         In addition, unapproved products subject to the PMA requirements must
receive prior FDA export approval in order to be marketed outside of the United
States unless they are approved for use by any member country of the European
Union or certain other countries, including Australia, Canada, Israel, Japan,
New Zealand, Switzerland and South Africa, in which case they can be exported to
any country provided that certain limited notification requirements are met.
There can be no assurance that the Company will meet the FDA's export
requirements or receive FDA export approval when such approval is necessary, or
that countries to which the devices are to be exported will approve the devices
for import. Failure of the




                                       12

<PAGE>   13



Company to meet the FDA's export requirements or obtain FDA export approval when
required to do so, or to obtain approval for import, could have a material
adverse effect on the Company's business, financial condition, cash flows and
results of operations.

         Regulatory approvals, if granted, may include significant limitations
on the indicated uses for which the product may be marketed. In addition, to
obtain such approvals, the FDA and certain foreign regulatory authorities may
impose numerous other requirements with which medical device manufacturers must
comply. FDA enforcement policy strictly prohibits the marketing of approved
medical devices for unapproved uses. Product approvals could be withdrawn for
failure to comply with regulatory standards or the occurrence of unforeseen
problems following initial marketing. The third-party manufacturers upon which
the Company depends to manufacture its products are required to adhere to
applicable FDA regulations regarding GMPs and similar regulations in other
countries, which include testing, control and documentation requirements.
Ongoing compliance with GMP regulations and other applicable regulatory
requirements will be monitored by periodic inspection by the FDA and by
comparable agencies in other countries. Failure to comply with applicable
regulatory requirements, including marketing or promoting products for
unapproved use, could result in, among other things, warning letters, fines,
injunctions, civil penalties, recall or seizure of products, total or partial
suspension of production, refusal of the government to grant premarket clearance
or approval for devices, withdrawal of approvals and criminal prosecution.
Changes in existing regulations or adoption of new governmental regulations or
policies could prevent or delay regulatory approval of the Company's products.
Certain material changes to medical devices also are subject to FDA review and
clearance or approval.

      The President recently signed into law the Food and Drug Administration
Modernization Act of 1997. This legislation makes changes to the device
provisions of the FDC Act and other provisions in the FDC Act affecting the
regulation of devices. Among other things, the changes will affect the premarket
approval process, and also will affect the FDA's investigational device
exemption process, data requirements and procedures relating to breakthrough
devices, tracking and postmarket surveillance, accredited third party review,
and the dissemination of off label information. The Company cannot predict how
or when these changes will be implemented or what effect the changes will have
on the regulation of the Company's products. There can be no assurance that the
new legislation will not impose additional costs or lengthen review times for
the Company's products.

      There can be no assurance that the Company will be able to obtain, on a
timely basis, or at all, FDA approval of the PMA for the Biofield Diagnostic
System or regulatory approvals or clearances for other products that the Company
may develop and delays in receipt of or failure to obtain such approvals or
clearances, the loss of previously obtained approvals, or failure to comply with
existing or future regulatory requirements would have a material adverse effect
on the Company's business, financial condition, cash flows and results of
operations.

LIMITATIONS ON THIRD-PARTY REIMBURSEMENT

      In the United States, suppliers of health care products and services are
greatly affected by Medicare, Medicaid and other government insurance programs,
as well as by private insurance reimbursement programs. Third-party payors
(Medicare, Medicaid, private health insurance companies and other organizations)
may affect the pricing or relative attractiveness of the Company's products by
regulating the level of reimbursement provided by such payors to the physicians
and clinics utilizing the Biofield




                                       13

<PAGE>   14



Diagnostic System or any other products that the Company may develop or by
refusing reimbursement. If examinations utilizing the Company's products were
not reimbursed under these programs, the Company's ability to sell its products
may be materially adversely affected. There can be no assurance that third-party
payors will provide reimbursement for use of the Biofield Diagnostic System or
any other products that the Company may develop.

      In international markets, reimbursement by private third-party medical
insurance providers, including governmental insurers and independent providers,
varies from country to country. In addition, such third-party medical insurance
providers may require additional information or clinical data prior to providing
reimbursement for a product. In certain countries, the Company's ability to
achieve significant market penetration may depend upon the availability of
third-party and governmental reimbursement. Revenues and profitability of
medical device companies may be affected by the continuing efforts of
governmental and third-party payors to contain or reduce the costs of health
care through various means.

UNCERTAINTIES REGARDING HEALTH CARE REFORM

      Several states and the U.S. government are investigating a variety of
alternatives to reform the health care delivery system and further reduce and
control health care spending. These reform efforts include proposals to limit
spending on health care items and services, limit coverage for new technology
and limit or control the price health care providers and drug and device
manufacturers may charge for their services and products, respectively. If
adopted and implemented, such reforms could have a material adverse effect on
the Company's business, financial condition, cash flows and results of
operations.

UNCERTAIN ABILITY TO PROTECT PATENTS AND PROPRIETARY TECHNOLOGY AND INFORMATION

      The Company's ability to compete effectively in the medical products
industry will depend on its success in protecting its proprietary technology,
both in the United States and abroad. The patent positions of medical products
companies generally involve complex legal and factual questions. The Company's
proprietary products and technology are the subject of nine U.S. patents owned
by the Company, and additional applications pending with the United States
Patent and Trademark Office ("PTO"). The Company has filed, and intends to
continue to file, patent applications in certain foreign jurisdictions covering
the patent claims that are the subject of U.S. patents and patent applications.
There can be no assurance that the PTO or foreign jurisdictions will grant the
Company's pending patent applications or that the Company will obtain any
patents or other protection for which it has applied. There can be no assurance
that patents issued to or licensed by or to the Company will not be challenged,
invalidated or circumvented, or that the rights granted thereunder will provide
any competitive advantage. The Company could incur substantial costs in
defending any patent infringement suits or in asserting any patent rights,
including those granted by third parties.

      Although the Company has entered into confidentiality and invention
agreements with its employees and consultants, there can be no assurance that
such agreements will be honored or that the Company will be able to protect its
rights to its unpatented trade secrets and know-how effectively. Moreover, there
can be no assurance that others will not independently develop substantially
equivalent proprietary information and techniques or otherwise gain access to
the Company's trade secrets and know-how. In addition, the Company may be
required to obtain licenses to patents or other proprietary rights from third
parties. There can be no assurance that any licenses required under any patents
or proprietary rights would be made




                                       14

<PAGE>   15



available on acceptable terms, if at all. If the Company does not obtain
required licenses, it could encounter delays in product development or find that
the development, manufacture or sale of products requiring such licenses could
be foreclosed. Additionally, the Company may, from time to time, support and
collaborate in research conducted by universities and governmental research
organizations. There can be no assurance that the Company will have or be able
to acquire exclusive rights to the inventions or technical information derived
from such collaborations or that disputes will not arise with respect to rights
in derivative or related research programs conducted by the Company or such
collaborators.

UNCERTAIN ABILITY TO MEET CAPITAL NEEDS

      The Company will require substantial additional funds for its research and
development programs, preclinical and clinical testing, operating expenses,
regulatory processes and manufacturing and marketing programs. The Company's
future capital requirements will depend on many factors, including the
following: the progress of its research and development projects; the progress
of preclinical and clinical testing; the time and cost involved in obtaining
regulatory approvals; the cost of filing, prosecuting, defending and enforcing
any patent claims and other intellectual property rights; competing
technological and market developments; changes and developments in the Company's
existing collaborative, licensing and other relationships and the terms of any
new collaborative, licensing and other arrangements that the Company may
establish; and the development of commercialization activities and arrangements.
Moreover, the Company's fixed commitments, including salaries and fees for
current employees and consultants, rent, payments under license agreements and
other contractual commitments are substantial and are likely to increase as
additional agreements are entered into and additional personnel are retained.
The Company does not expect to generate a positive internal cash flow for at
least several years due to expected increases in capital expenditures, working
capital needs and ongoing losses, including the expected cost of commercializing
the Biofield Diagnostic System. However, the Company's cash requirements may
vary materially from those now planned due to the progress of research and
development programs, results of clinical testing, relationships with strategic
partners, if any, changes in the focus and direction of the Company's research
and development programs, competitive and technological advances, the FDA and
foreign regulatory processes and other factors.

      The Company will need additional capital to fund its future operations
through public or private financings or collaborative licensing or other
arrangements with corporate partners. If additional funds are raised by issuing
equity securities, further dilution to existing stockholders will result and
future investors may be granted rights superior to those of existing
stockholders. There can be no assurance, however, that additional financing will
be available when needed, or if available, will be available on acceptable
terms. Insufficient funds may prevent the Company from implementing its business
strategy or may require the Company to delay, scale back or eliminate certain of
its research and product development programs or to license to third parties
rights to commercialize products or technologies that the Company would
otherwise seek to develop itself.

DEPENDENCE ON QUALIFIED PERSONNEL

      Due to the specialized scientific nature of the Company's business, the
Company is highly dependent upon its ability to attract and retain qualified
scientific, technical and managerial personnel. The loss of the services of
existing personnel as well as the failure to recruit key scientific, technical
and managerial personnel in a timely manner would be detrimental to the
Company's research and development programs




                                       15

<PAGE>   16



and to its business. The Company's anticipated growth and expansion into areas
and activities requiring additional expertise, such as marketing, will require
the addition of new management personnel. Competition for qualified personnel is
intense and there can be no assurance that the Company will be able to continue
to attract and retain qualified personnel necessary for the development of its
business.

POTENTIAL PRODUCT LIABILITY

      The Company's business exposes it to potential product liability risks
which are inherent in the testing, manufacturing and marketing of cancer
detection products. Significant litigation, not involving the Company, has
occurred in the past based on allegations of false negative diagnoses of cancer.
While the Biofield Diagnostic System does not purport to diagnose any patient,
there can be no assurance that the Company will not be subjected to future
claims and potential liability. While the Company maintains insurance against
product liability and defense costs, there can be no assurance that claims
against the Company arising with respect to its products will be successfully
defended or that the insurance carried by the Company will be sufficient to
cover liabilities arising from such claims. A successful claim against the
Company in excess of the Company's insurance coverage could have a material
adverse effect on the Company. Furthermore, there can be no assurance that the
Company will be able to continue to obtain or maintain product liability
insurance on acceptable terms.

POTENTIAL FOR ENVIRONMENTAL LIABILITY

      A portion of the Company's manufacturing processes involves the controlled
use of potentially hazardous materials. The Company may in the future become
subject to stringent federal, state and local laws, rules, regulations and
policies governing the use, generation, manufacture, storage, air emission,
effluent discharge, handling and disposal of such materials. There can be no
assurance that the Company will not incur significant future costs to comply
with environmental laws, rules, regulations and policies, or that the business,
financial position, cash flows or results of operations of the Company will not
be materially and adversely affected by current or future environmental laws,
rules, regulations and policies or by any releases or discharges of hazardous
materials.

AVAILABILITY OF PREFERRED STOCK FOR ISSUANCE

      In addition to its authorized shares of Common Stock, the Company's Fourth
Amended and Restated Certificate of Incorporation, as amended, authorizes the
issuance of up to 2,000,000 shares of preferred stock. The Board of Directors of
the Company may at any time determine to issue shares of preferred stock with
the rights and preferences to be set by the Board of Directors in its sole
discretion. The rights and preferences of any such preferred stock may be
superior to those of the Common Stock and thus may adversely affect the rights
of the holders of Common Stock.

POSSIBLE ANTI-TAKEOVER EFFECTS OF DELAWARE LAW

       The Company is subject to the provisions of Section 203 of the General
Corporation Law of the State of Delaware. In general, Section 203 prohibits a
publicly held Delaware corporation from engaging in a "business combination"
with an "interested stockholder" for a period of three years after the date of
the transaction in which the person becomes an interested stockholder, unless
the business combination is approved in a prescribed manner or unless the
interested stockholder acquires at least 85% of the




                                       16

<PAGE>   17



corporation's voting stock (excluding shares held by certain designated
stockholders) in the transaction in which it becomes an interested stockholder.
A "business combination" includes mergers, asset sales and other transactions
resulting in a financial benefit to the interested stockholder. Subject to
certain exceptions, an "interested stockholder" is a person who, together with
affiliates and associates, owns, or within the previous three years did own, 15%
or more of the corporation's voting stock. This provision of the Delaware law
could delay and make more difficult a business combination even if the business
combination would be beneficial, in the short term, to the interests of the
Company's stockholders and also could limit the price certain investors might be
willing to pay in the future for shares of Common Stock.

NO DIVIDENDS

      The Company has never declared or paid any cash dividends on its capital
stock and does not intend to pay any cash dividends in the foreseeable future.
The Company currently anticipates that it will retain all its earnings for use
in the operation and expansion of its business and, therefore, does not
anticipate that it will pay any cash dividends in the foreseeable future.

POSSIBLE VOLATILITY OF STOCK PRICE

      The price of the Company's Common Stock has fluctuated substantially since
its initial public offering on March 19, 1996. The market price of the shares of
the Common Stock, like that of the common stock of many other medical device
companies, is likely to continue to be highly volatile. Factors such as the
timing and results of clinical trials by the Company or its competitors,
governmental regulation, healthcare legislation, developments in patent or other
proprietary rights of the Company or its competitors, including litigation,
fluctuations in the Company's operating results, and market conditions for
medical device company stocks and life science stocks in general, could have a
significant impact on the future price of the Common Stock.

CONTROL BY MANAGEMENT AND PRINCIPAL STOCKHOLDERS

       After giving effect to the consummation of the 1997 Private Placement and
the Warrant Exchange, at December 17, 1997, officers and directors of the
Company and stockholders owning more than five percent of the Common Stock,
together with their affiliates, beneficially own approximately 59.9% of the
outstanding Common Stock. Officers and directors of the Company and stockholders
owning more than five percent of the Common Stock are able to elect all members
of the Company's Board of Directors and determine corporate actions. Such
concentration of ownership may have the effect of delaying, deferring or
preventing a change in control of the Company.

SHARES ELIGIBLE FOR FUTURE SALE; OUTSTANDING REGISTRATION RIGHTS

      After giving effect to the consummation of the 1997 Private Placement and
the Warrant Exchange, at December 17, 1997, the Company had 10,029,609 shares of
Common Stock outstanding, and approximately 3,430,193 of such shares were freely
tradable by the holders thereof without limitations under the Securities Act.
The Company issued 2,867,670 shares of Common Stock in the 1997 Private
Placement, and has registered for resale 2,797,829 of such shares pursuant to
the registration statement of which this Prospectus forms a part. The Company
issued 643,639 shares of Common Stock in connection with the Warrant Exchange,
and has registered for resale 79,570 of such shares pursuant to the registration
statement of which




                                       17

<PAGE>   18



this Prospectus forms a part. All such shares so registered may be resold by the
holders thereof without restriction as set forth in this Prospectus, subject, in
the case of the Warrant Exchange shares, to "lock-up" agreements described
below. See "Selling Stockholders" and "Plan of Distribution." Of the other
shares of Common Stock outstanding as of December 17, 1997, 2,051,696 shares of
Common Stock were held by officers, directors and other stockholders who may be
deemed to be "affiliates" of the Company and who therefore are generally subject
to the volume and other limitations of Rule 144 promulgated under the Securities
Act ("Rule 144"). The holders of all or substantially all of such 2,051,696
shares have registration rights with respect to their shares, and none of such
shares of Common Stock have been registered for resale pursuant to the
registration statement of which this Prospectus forms a part. The holders of all
or substantially all of such 2,051,696 shares have signed "lock-up" agreements
pursuant to which they agreed not to sell or offer to sell any of their shares
of Common Stock without the prior written consent of the Hambrecht & Quist, LLC,
the placement agent for the 1997 Private Placement, during the period from the
closing of the 1997 Private Placement to and including 90 days from the date of
this Prospectus. In addition, as of December 17, 1997, 1,036,403 shares of
Common Stock were held by certain other stockholders who have signed "lock-up"
agreements as described above. Upon expiration of the 90 day "lock-up" period,
such 1,036,403 shares will be freely tradable by the holders thereof provided
that such holders do not become "affiliates" of the Company. Furthermore, the
holders of the shares issued in connection with the Warrant Exchange have signed
"lock-up" agreements pursuant to which they agreed not to sell or offer to sell
such shares without the prior written consent of the Company for a period of one
year from the date of issuance of such shares. In addition to any sales of such
shares which may be made pursuant to this Prospectus, after stockholders have
held their shares for a period of one year, they will be eligible to sell their
shares pursuant to the volume and other limitations of Rule 144, and those who
are not affiliates of the Company will be able to sell such shares without
restriction under Rule 144 after they have held such shares for two years. Sales
of substantial amounts of Common Stock in the public market, or the perception
that such sales could occur, could adversely affect the trading price of the
Common Stock and could impair the Company's future ability to raise capital
through an offering of its equity securities.

OUTSTANDING OPTIONS, WARRANTS AND OTHER RIGHTS

      After giving effect to the consummation of the 1997 Private Placement and
the Warrant Exchange at December 17, 1997, options to purchase a total of
1,983,969 shares of Common Stock were outstanding with a weighted average
exercise price of $5.60 per share, of which options to purchase 1,335,641 shares
of Common Stock were exercisable. In addition, as of such date, an additional
552,624 shares of Common Stock were available for future option grants under the
Company's stock option plans. As of such date, warrants to purchase a total of
396,762 shares of Common Stock were outstanding with a weighted average exercise
price of $9.83 per share. An aggregate of 1,166,572 shares of Common Stock
issuable upon the exercise of options and warrants held by officers, directors
and certain other stockholders of the Company are subject to "lock-up
agreements." See "Risk Factors--Shares Eligible for Future Sale." To the extent
that the aforementioned options or warrants are exercised, the interests of the
Company's stockholders would be diluted. Moreover, as long as such options and
warrants are outstanding, the terms upon which the Company will be able to
obtain additional equity capital may be adversely affected since the holders of
the outstanding options and warrants and rights can be expected to exercise
them, to the extent they are able to, at a time when the Company would, in all
likelihood, be able to obtain any needed capital on terms more favorable to the
Company than those provided in the options and warrants. The Company has
registered for sale under the Securities Act the shares of Common Stock included
in its stock option plans, shares of




                                       18

<PAGE>   19

      The following table sets forth information concerning Shares beneficially
owned as of December 17, 1997, after giving effect to the 1997 Private Placement

be offered from time to time pursuant to this Prospectus. Other than their
ownership of the Company's securities, none of the Selling Stockholders has had
any material relationship with the Company within the past three years, other
than as described in the footnotes to the table. The table has been prepared
based on information furnished to the Company by American Stock Transfer & Trust
Company and/or by or on behalf of the Selling Stockholders.

      Any or all of the Shares listed below may be offered for sale by the
Selling Stockholders from time to time and therefore no estimate can be given as

termination of this offering. Except as otherwise indicated, the Selling
Stockholders listed in the table have sole voting and investment powers with
respect to the Shares indicated.

                              PLAN OF DISTRIBUTION

            The Shares offered by this Prospectus may be sold from time to time
by the Selling Stockholders or by transferees thereof. As of the date hereof,
the Company is not aware of any underwriting arrangements that have been entered
into by the Selling Stockholders. The distribution of the Shares by the Selling
Stockholders or by transferees thereof may be effected in one or more
transactions that may take place in the over-the-counter market, in privately
negotiated transactions, in the Nasdaq National Market or otherwise, at
prevailing market prices at the time of sale, prices related to prevailing
market prices, or as may be negotiated at the time of sale. Without limiting the
generality of the foregoing, the Shares offered by the Selling Stockholders or
by transferees thereof may be sold by one or more of the following methods,
without limitation: (a) ordinary brokerage transactions and transactions in
which the broker solicits purchasers; (b) a block trade in which a 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 or
other "block" sales; (c) purchases by a broker or dealer as principal and resale
by such broker or dealer for its account pursuant to this Prospectus; and (d)
face-to-face transactions between sellers and purchasers without a
broker-dealer. The Shares may also be publicly offered through agents,
underwriters or dealers. Underwriter's discounts and usual and customary or
specifically negotiated brokerage fees or commissions may be paid by a Selling
Stockholder in connection with sales of the Shares. To the extent required, the
number of Shares to be sold, the name of the Selling Stockholder, the purchase
price, the name of any agent or broker, and any applicable commissions,
discounts or other compensation to such agents or brokers with respect to a
particular offering will be set forth in a Prospectus Supplement.

   The Selling Stockholders and transferees thereof may enter into hedging
transactions with broker-dealers with respect to the Shares. In connection with
such transactions, broker-dealers may engage in short sales of the Shares in the
course of hedging the positions they assume with the Selling Stockholders and
transferees thereof. The Selling Stockholders and transferees thereof may also
sell the Shares short and redeliver the Shares to close out the short positions.
The Selling Stockholders and transferees thereof may also enter into option or
other transactions with broker-dealers which require the delivery to
broker-dealers of the Shares. The Selling Stockholders and transferees thereof
may also loan or pledge the Shares to a financial institution or a broker-dealer
and the financial institution or the broker-dealer may sell the Shares so loaned
or upon a default the financial institution or the broker-dealer may effect
sales of the pledged shares. In addition to the foregoing, the Selling
Stockholders and transferees thereof may, from time to time, enter into other
types of hedging transactions.

   In order to comply with certain state securities laws, if applicable, the
Shares will be sold in such jurisdictions only through registered or licensed
brokers or dealers. In certain states, the Shares may not be sold unless such
Shares have been registered or qualified for sale in such state or an exemption
from registration or qualification is available and is complied with.

   Under applicable rules and regulations under the Exchange Act, any person
engaged in a distribution of the Shares may not simultaneously engage in
market-making activities with respect to such Shares for a period of one or five
business days prior to the commencement of such distribution. In addition to,
and without limiting, the foregoing, each of the Selling Stockholders and any
other person participating in a distribution will be subject to the applicable
provisions of the Exchange Act and the rules and regulations thereunder,
including, without limitation, Regulation M, which provisions may limit the
timing of purchases and sales of any of the Shares by the Selling Stockholders
or any such other person. All of the foregoing may affect the marketability of
the Shares.
