                          MIRAVANT MEDICAL TECHNOLOGIES

     Miravant Medical  Technologies is engaged in the integrated  development of
drugs and medical device  products for use in  PhotoPoint(TM),  our  proprietary
technologies for photodynamic  therapy.  PhotoPoint is a medical procedure which
integrates  the use of  proprietary  light-activated  drugs,  proprietary  light
producing devices and light delivery devices to achieve selective  photochemical
destruction of diseased  cells.  We believe that PhotoPoint has the potential to
be a safe,  cost-effective,  minimally invasive primary or adjunctive  treatment
for  indications  in a  broad  number  of  disease  areas,  including  oncology,
ophthalmology, urology, dermatology and cardiovascular disease. We are currently
conducting  clinical trials in ophthalmology and oncology.  Our current clinical
trials are testing our leading drug candidate,  SnET2 or tin ethyl etiopurpurin.
We are developing products in collaboration with our various corporate partners.

     Photodynamic  therapy is a minimally  invasive medical  procedure that uses
photoselective,  or  light-activated,  drugs to treat or diagnose  disease.  The
technology  involves three  components:  photoselective  drugs,  light producing
devices and light delivery devices.

     Photoselective  drugs  transform  light  energy into  chemical  energy in a
manner  similar  to  the  action  of   chlorophyll  in  green  plants.   Certain
photoselective   drugs   accumulate   and  are  retained  in   fast-growing   or
hyperproliferating,  cells.  Hyperproliferation  is a  characteristic  of  cells
associated with a variety of diseases such as cancer, certain vascular disorders
and skin diseases such as psoriasis.

     A photoselective  drug is typically  administered by intravenous  injection
and over time the drug associates with  hyperproliferating  tissues. The drug is
inactive  until  exposed  to  light of a  specific  wavelength,  which  can vary
depending on the drug's  molecular  structure.  Exposing the target cells to the
appropriate  light  wavelength  permits  activation  of the  retained  drug  and
initiates a chemical  reaction that generates a highly  reactive form of oxygen.
High  concentrations  of this form of oxygen lead to destruction of the cellular
membrane and,  ultimately,  cell death. The response of the target cells depends
on, among other factors,  the drug dose,  the amount of light energy  delivered,
the physiology of the cell and the  vasculature in the diseased  areas.  Neither
the drug nor the light on its own can cause the  desired  effect.  The drug is a
catalyst which transfers  energy.  The chemical reaction stops when the light is
turned off.  The  potential  result of this process is that  diseased  cells are
destroyed with minimal damage to surrounding normal tissues.

     Our objective is to apply PhotoPoint -- our  photodynamic  therapy systems,
which integrate photoselective drugs, light producing devices and light delivery
devices -- as a primary  therapy in targeted  disease areas and as an adjunct to
surgery or other  therapies in these same or other disease  areas.  Although the
potential  applications  for our  PhotoPoint  systems are  numerous,  in 1998 we
announced  our  intention to refine our focus to target large  potential  market
opportunities or diseases with significant  unmet medical needs. By doing so, we
believe we may be able to accelerate  regulatory processes where appropriate and
facilitate   commercial  success.  In  addition,   to  facilitate   development,
regulatory approval, manufacturing,  marketing and distribution of our products,
we have or seek to form strategic  collaborations  with partners who are leaders
in our targeted disease areas.

     We were incorporated in Delaware in 1989 and, effective September 15, 1997,
changed our name from PDT, Inc. to Miravant Medical Technologies.  Our executive
offices and the  offices of our three  subsidiaries,  Miravant  Pharmaceuticals,
Inc., Miravant Systems, Inc. and Miravant  Cardiovascular,  Inc., are located at
336 Bollay Drive, Santa Barbara, California 93117. Our telephone number is (805)
685-9880.  Unless otherwise  indicated,  all references to us include us and our
subsidiaries.


                                  RISK FACTORS

     We do not provide  forecasts of potential  future  operational or financial
performance.  While management is optimistic about our long-term prospects,  the
following  issues and  uncertainties,  among  others,  should be  considered  in
evaluating our outlook. This prospectus, as well as the information incorporated
by  reference,  contains  forward-looking  statements  which  involve  known and
unknown risks and  uncertainties.  These statements  relate to our future plans,
objectives,  expectations and intentions.  These statements may be identified by
the use of  words  such as  "expects,"  "anticipates,"  "intends,"  "plans"  and
similar  expressions.  Our actual  results  could differ  materially  from those
discussed  in these  statements.  The factors  listed  below are not intended to
represent a complete  list of the general or specific  risks that may affect us.
It should be recognized that other risks may be significant, presently or in the
future,  and the risks set forth  below may affect us to a greater  extent  than
indicated.

HISTORY OF OPERATING LOSSES AND UNCERTAINTY OF FUTURE PROFITABILITY

     We have not had revenues generated from sales of our drugs and only limited
revenues  have been  generated  from sales of our devices.  We have  experienced
operating  losses  since  our  inception  in 1989  and  have  not  yet  achieved
profitability.  We have an accumulated  deficit of $108.9 million  (audited) and
$115.0  million  (unaudited)  as of  December  31,  1998  and  March  31,  1999,
respectively.  We do not expect to achieve significant levels of revenues for at
least  several  years.  Our  revenues  to  date  have  consisted,  and  for  the
foreseeable  future are  expected to  consist,  principally  of grants  awarded,
payments for our devices,  license  fees,  royalties,  clinical  reimbursements,
milestone  payments and  interest  income.  Our ability to generate  significant
revenues in the future is dependent upon:

     *    Successfully completing our research or product development efforts or
          those of our collaborative partners;
     *    Successfully   transforming  our  drugs  or  devices  currently  under
          development into marketable products;
     *    Obtaining the required regulatory approvals;
     *    Manufacturing  our products at an acceptable cost and with appropriate
          quality;
     *    Favorable acceptance of any products marketed; and
     *    Successful marketing and sales efforts of our corporate partner(s).


     We may not be  successful  in  achieving  any of  these,  and if we are not
successful,  our business,  financial  condition and operating  results could be
adversely  affected.  The time frame  necessary  to achieve  these goals for any
individual  product is long and uncertain.  Most of our products currently under
development  will require  significant  additional  research and development and
preclinical  studies  and  clinical  trials,  and all  will  require  regulatory
approval  prior to  commercialization.  The  likelihood  of our success  must be
considered  in  light of  these  and  other  problems,  expenses,  difficulties,
complications and delays.


UNPROVEN SAFETY AND EFFICACY; CLINICAL TRIALS

     All of our  drug and  device  products  currently  under  development  will
require  extensive  preclinical  studies and clinical trials prior to regulatory
approval for  commercial  use. None of our products have  completed  testing for
efficacy  or safety in humans.  Some of the risks and  uncertainties  related to
safety and  efficacy  testing  and the  completion  of  preclinical  studies and
clinical trials include:

     *    Our ability to demonstrate to the Food and Drug  Administration or FDA
          that SnET2 or any other of our products is safe and efficacious;
     *    Our ability to successfully  commence and complete the testing for any
          of our compounds within any specified time period, if at all;
     *    Clinical  data  reported  may  change  as a result  of the  continuing
          evaluation of patients;
     *    Data obtained from preclinical studies and clinical trials are subject
          to varying  interpretations which can delay, limit or prevent approval
          by the FDA or other regulatory authorities;
     *    Problems in research and development,  preclinical studies or clinical
          trials that will cause us to delay, suspend or cancel clinical trials;
          and
     *    As a result of changing  economic  considerations,  competitive or new
          technological  developments,  market approvals or changes, clinical or
          regulatory conditions,  or clinical trial results, our focus may shift
          to other indications, or we may determine not to further pursue one or
          more of the indications currently being pursued.

     To date, we have limited experience in conducting  clinical trials. We will
either need to rely on third parties,  including our collaborative  partners, to
design and conduct any  required  clinical  trials or expend  resources  to hire
additional   personnel  or  engage  outside  consultants  or  contract  research
organizations  to  administer  the clinical  trials.  We may not be able to find
appropriate  third parties to design and conduct  clinical  trials or we may not
have the resources to administer clinical trials in-house.

RELIANCE ON COLLABORATIVE PARTNERS

     We have entered into collaborative  relationships with certain corporations
and academic institutions for the research and development,  preclinical studies
and clinical  trials,  licensing,  manufacturing,  sales and distribution of our
products. These collaborative relationships include:

     *    In 1995, we entered into a  collaborative  agreement  with Pharmacia &
          Upjohn, Inc. or Pharmacia & Upjohn,  which was subsequently amended in
          1996,  1998 and 1999,  pursuant  to which we  granted to  Pharmacia  &
          Upjohn an  exclusive  worldwide  license to use,  distribute  and sell
          SnET2 for  therapeutic  or  diagnostic  applications  in  photodynamic
          therapy for ophthalmology, oncology and urology;
     *    Collaborations  with  Fresenius  Kabi or  Fresenius,  for  final  drug
          formulation   and  drug  product   supply,   Fresenius   manufacturing
          facilities  were  previously  owned by  Pharmacia & Upjohn and sold to
          Fresenius in June 1998;
     *    Collaborations with Medicis Pharmaceutical Corporation or Medicis, for
          the clinical development of PhotoPoint in dermatology;
     *    Collaborations  with  Chiron  Diagnostics  or  Chiron,  for the  early
          detection and treatment of lung cancer;
     *    Collaborations  with  Iridex  Corporation  or  Iridex,  Ramus  Medical
          Technologies or Ramus and Xillix Technologies Corp. or Xillix, for the
          development of devices for use in  photodynamic  therapy in the fields
          of ophthalmology,  cardiovascular disease and oncology,  respectively;
          and
     *    Collaborations with Boston Scientific Corporation or Boston Scientific
          and Cordis  Corporation for the co-development of catheters for use in
          photodynamic therapy.

     The amount of royalty revenues and other payments,  if any, ultimately paid
by Pharmacia & Upjohn  globally to Miravant for sales of SnET2 is dependent,  in
part,  on the amount  and  timing of  resources  Pharmacia  & Upjohn  commits to
research  and  development,   preclinical   studies  and  clinical  testing  and
regulatory  and marketing and sales  activities,  which are entirely  within the
control of Pharmacia & Upjohn. Pharmacia & Upjohn may not pursue the development
and  commercialization  of SnET2  and/or  may not  perform  its  obligations  as
expected.  Also,  we have  not yet  entered  into any  definitive  collaborative
agreements   with  Boston   Scientific,   Cordis,   Medicis  or  Chiron.   These
collaborations  may not  culminate in  definitive  collaborative  agreements  or
marketable products. Additionally, Iridex, Ramus and Xillix may not continue the
development of devices for use in photodynamic  therapy, or such development may
not result in marketable products.

     We are  currently at various  stages of  discussions  with other  companies
regarding  the   establishment  of   collaborations.   Our  current  and  future
collaborations  are  important  to us because  they  allow us greater  access to
funds, to research, development or testing resources and to manufacturing, sales
or  distribution  resources  that we would  otherwise  not  have.  We  intend to
continue  to rely on such  collaborative  arrangements.  Some of the  risks  and
uncertainties related to the reliance on collaborations include:

     *    Our ability to negotiate acceptable collaborative arrangements;
     *    Future or existing collaborative arrangements may not be successful or
          may  not  result  in  products  that  are  marketed  or  sold;
     *    Such   collaborative   relationships  may  limit  or  restrict  us;
     *    Collaborative partners are free to pursue alternative  technologies or
          products   either  on  their  own  or  with  others,   including   our
          competitors, for the diseases targeted by our programs and products;
     *    Our partners may terminate the  relationships  described above, and we
          may  be  required  to  seek  other  partners,  or  expend  substantial
          additional resources to pursue these activities  independently.  These
          efforts may not be successful; and
     *    Our ability to manage,  interact  and  coordinate  our  timelines  and
          objectives with our strategic partners.

ADDITIONAL FINANCING REQUIREMENTS AND UNCERTAINTY OF CAPITAL FUNDING

     We have incurred  negative cash flows from  operations  since our inception
and have expended substantial funds on our research and development programs and
preclinical  studies and clinical testing. We may require substantial funding to
continue or  undertake  our  research and  development  activities,  preclinical
studies and clinical testing and manufacturing,  marketing,  sales, distribution
and administrative activities. Our existing capital resources, together with the
proceeds from future  offerings and future cash flows,  may not be sufficient to
fund our future operations.

COMPETITION AND TECHNOLOGICAL UNCERTAINTY

     Many of our competitors have substantially greater financial, technical and
human resources than we do, and may also have  substantially  greater experience
in  developing  products,  conducting  preclinical  studies or clinical  trials,
obtaining  regulatory  approvals and manufacturing and marketing.  Further,  our
competitive position could be materially adversely affected by the establishment
of patent  protection  by our  competitors.  The existing  competitors  or other
companies  may succeed in  developing  technologies  and products  that are more
safe,  effective or  affordable  than those being  developed by us or that would
render our technology and products less competitive or obsolete.

LIABILITY OR RECALL

     The use of our products in clinical trials and the sale of our products may
expose us to liability  claims.  These claims could be made directly by patients
or  consumers,  or by  companies,  institutions  or others  using or selling our
products. The following are some of the risks related to liability and recall:

     *    We are subject to the inherent risk that a  governmental  authority or
          third party may require the recall of one or more of our products;
     *    We have not  obtained  liability  insurance  that would  cover a claim
          relating to the use or recall of our products;
     *    In the absence of  liability  insurance,  claims made  against us or a
          product recall could have a material adverse effect on us;
     *    If we obtain insurance  coverage in the future,  this coverage may not
          be available at a reasonable cost and in amounts sufficient to protect
          us against  claims  that could have a material  adverse  effect on our
          financial condition and prospects; and
     *    Liability  claims  relating to our products or a product  recall could
          negatively  effect  our  ability  to  obtain  or  maintain  regulatory
          approval for our products.

     We have agreed to indemnify certain of our  collaborative  partners against
certain potential  liabilities relating to the manufacture and sale of SnET2 and
PhotoPoint light devices.

GOVERNMENT REGULATION

     The production  and marketing of our products and our ongoing  research and
development,  preclinical  studies and clinical trial  activities are subject to
extensive  regulation  and review by numerous  governmental  authorities  in the
United  States,  including the FDA, and in other  countries.  All drugs and most
medical  devices  we develop  must  undergo  rigorous  preclinical  studies  and
clinical trials and an extensive regulatory approval process administered by the
FDA under the Food,  Drug and Cosmetic Act or FDC Act,  and  comparable  foreign
authorities,  before they can be marketed.  These processes involve  substantial
cost and can often take many years.  We have limited  experience in, and limited
resources  available  for  regulatory  activities.  Failure  to comply  with the
applicable   regulatory   requirements  can,  among  other  things,   result  in
non-approval,  suspensions of regulatory approvals,  fines, product seizures and
recalls, operating restrictions,  injunctions and criminal prosecution. To date,
none of our product  candidates being developed have been submitted for approval
or  have  been  approved  by the  FDA  or any  other  regulatory  authority  for
marketing. Some of the risks and uncertainties include:

     *    Delays in obtaining approval or rejections due to regulatory review of
          each submitted new drug, device or combination drug/device application
          or product  license  application,  as well as  changes  in  regulatory
          policy during the period of product development;
     *    If  regulatory  approval of a product is granted,  such  approval  may
          entail limitations on the uses for which the product may be marketed;
     *    If regulatory approval is obtained,  the product, our manufacturer and
          the  manufacturing  facilities  are  subject to  continual  review and
          periodic inspections;
     *    If regulatory  approval is obtained,  such approval may be conditional
          on the  satisfaction  of the completion of clinical  trials or require
          additional clinical trials;
     *    Later  discovery  of  previously  unknown  problems  with  a  product,
          manufacturer or facility may result in restrictions on such product or
          manufacturer,  including withdrawal of the product from the market and
          litigation; and
     *    Photodynamic  therapy  products  have been  categorized  by the FDA as
          combination  drug-device  products.  If current or future  drug/device
          products do not continue to be categorized for regulatory  purposes as
          combination products, then:
          *    The FDA may require separate drug and device submissions; and
          *    The FDA may require separate approval by regulatory authorities.

     Internationally, beginning in 1995, a new regulatory system to approve drug
market  registration  applications  was implemented in the European Union or EU.
The system provides for new centralized, decentralized and national registration
procedures through which a company may obtain drug marketing registrations.  The
centralized  procedure allows for expedited review and approval of biotechnology
and high  technology/innovative  product  marketing  applications  by a  central
Committee for Proprietary Medicinal Products. The decentralized procedure allows
a company to  petition  individual  EU member  states to review and  recognize a
market  application  previously  approved  in one member  state by the  national
route. Some of the international risks and uncertainties include:

     *    Foreign  regulatory   requirements  governing  testing,   development,
          marketing, licensing, pricing and/or distribution of drugs and devices
          in other countries;

     *    Our drug products may not qualify for the centralized review procedure
          or we may not be able to obtain a  national  market  application  that
          will be accepted by other EU member states;
     *    Our devices must also meet the new Medical Device Directive  effective
          in Europe  in 1998.  The  Directive  requires  that our  manufacturing
          quality  assurance  systems and compliance  with  technical  essential
          requirements  be certified  with a CE Mark  authorized by a registered
          notified body of an EU member state prior to free sale in the EU; and
     *    Registration  and approval of a photodynamic  therapy product in other
          countries,  such as  Japan,  may  include  additional  procedures  and
          requirements,  nonclinical and clinical  studies,  and may require the
          assistance of native corporate partners.

OTHER LAWS; FUTURE LEGISLATION OR REGULATIONS

     In addition to the regulations for drug or device approvals, we are subject
to  regulation  under state,  federal or other law,  including  regulations  for
worker occupational safety,  laboratory practices,  environmental protection and
hazardous  substance  control.  We  continue  to make  capital  and  operational
expenditures  for  protection  of the  environment  in  amounts  which  are  not
material.  Some of the  risks  and  uncertainties  related  to laws  and  future
legislation or regulations include:

     *    Our future  capital and  operational  expenditures  may  increase  and
          become material;
     *    We may also be subject to other  present and  possible  future  local,
          state, federal and foreign regulation;
     *    Heightened  public  awareness  and  concerns  regarding  the growth in
          overall health care  expenditures in the United States,  combined with
          the  continuing  efforts  of  governmental  authorities  to contain or
          reduce costs of health care,  may result in the  enactment of national
          health care reform or other  legislation  or  regulations  that impose
          limits  on the  number  and type of  medical  procedures  which may be
          performed  or which  have the  effect  of  restricting  a  physician's
          ability to select specific products for use in certain procedures;
     *    Such new  legislation or regulations may materially  adversely  affect
          the demand for our products.  In the United  States,  there have been,
          and we expect that there will  continue to be, a number of federal and
          state  legislative  proposals  and  regulations  to implement  greater
          governmental control in the health care industry;
     *    The announcement of such proposals may materially adversely affect our
          ability to raise capital or to form collaborations; and
     *    Legislation or regulations that impose  restrictions on the price that
          may be charged  for  health  care  products  or  medical  devices  may
          adversely affect our results of operations.

     We are unable to predict  the  likelihood  of adverse  effects  which might
arise from future  legislative or  administrative  action,  either in the United
States or abroad.

HEALTH CARE REIMBURSEMENT

     Our products may not be covered by the various  health care  providers.  If
they  are not  covered,  our  products  may or may not be  purchased  or sold as
expected.  Our ability to commercialize our products successfully may depend, in
part,  on the  extent to which  reimbursement  for these  products  and  related
treatment  will be available  from  collaborative  partners,  government  health
administration  authorities,  private health insurers, managed care entities and
other  organizations.  These payers are  increasingly  challenging  the price of
medical products and services and establishing protocols and formularies,  which
effectively  limit  physicians'  ability  to  select  products  and  procedures.
Uncertainty  exists  as to the  reimbursement  status of  health  care  products
(especially innovative technologies).  Additionally,  reimbursement coverage, if
available,  may not be adequate to enable us to achieve market acceptance of our
products  or  to  maintain  price  levels   sufficient  for  realization  of  an
appropriate return on our products.

LIMITED MANUFACTURING AND MARKETING CAPABILITY AND EXPERIENCE

     To  be  successful,   our  products  must  be  manufactured  in  commercial
quantities under current Good Manufacturing  Practices or GMP, prescribed by the
FDA and at  acceptable  costs.  Although  we  intend  to  manufacture  drugs and
devices,  we have not yet  manufactured  any products in  commercial  quantities
under GMP and have no experience in such commercial manufacturing.  We currently
have the capacity, in conjunction with our manufacturing partners Fresenius Kabi
and Iridex,  to manufacture  products at certain  commercial  levels and will be
able to do so upon  FDA  approval.  If we  receive  an FDA or  other  regulatory
approval we may need to expand our manufacturing  capabilities  and/or depend on
our  collaborators,   licensees  or  contract  manufacturers  for  the  expanded
commercial   manufacture  of  our  products.  If  we  expand  our  manufacturing
capabilities,  we  will  need to  expend  substantial  funds,  hire  and  retain
significant additional personnel and comply with extensive  regulations.  We may
not be able to expand  successfully or we may be unable to manufacture  products
in increased commercial  quantities for sale at competitive prices.  Further, we
may  not  be  able  to  enter  into  future   manufacturing   arrangements  with
collaborators,  licensees,  or contract  manufacturers on acceptable terms or at
all. If we are not able to expand our  manufacturing  capabilities or enter into
additional  commercial  manufacturing  agreements,  our business growth could be
limited and could be materially and adversely affected.

     We  have  limited   experience  in  marketing,   distributing  and  selling
pharmaceutical or medical device products. We will need to develop a sales force
or rely on our  collaborators or licensees or make  arrangements  with others to
provide  for  the  marketing,  distribution  and  sale of our  products.  We are
currently  relying  on  Pharmacia  & Upjohn  and  Iridex  for these  needs.  Our
marketing, distribution and sales capabilities or current or future arrangements
with third parties for such  activities  may not be adequate for the  successful
commercialization of our products.

UNCERTAINTY REGARDING PATENTS AND PROPRIETARY TECHNOLOGY

     Our success  will depend,  in part,  on our and our  licensors'  ability to
obtain, assert and defend our patents, protect trade secrets and operate without
infringing the proprietary  rights of others.  The exclusive license relating to
various drug compounds,  including our leading drug candidate  SnET2, may become
non-exclusive  if we fail to satisfy certain  development and  commercialization
objectives.  The  termination  or  restriction of our rights under this or other
licenses  for any reason  would  likely  have a material  adverse  impact on our
business  and  financial  condition.  Although  we  believe we should be able to
achieve such objectives, we may not be successful.

     The patent position of pharmaceutical and medical device firms generally is
highly uncertain. Some of the risks and uncertainties include:

     *    The patent  applications  owned by or licensed to us may not result in
          issued patents;
     *    Our issued patents may not provide us with  proprietary  protection or
          competitive advantages;
     *    Our issued patents may be infringed upon or designed around by others;
     *    Our issued  patents may be challenged by others and held to be invalid
          or unenforceable; and
     *    The patents of others may have a material adverse effect on us.

     We are aware that our  competitors  and  others  have been  issued  patents
relating to photodynamic  therapy.  In addition,  our competitors and others may
have  been  issued  patents  or  filed  patent  applications  relating  to other
potentially  competitive  products  of  which  we are not  aware.  Further,  our
competitors  and others may in the future file  applications  for, or  otherwise
obtain proprietary  rights to, such products.  These existing or future patents,
applications  or rights  may  conflict  with our or our  licensors'  patents  or
applications.  Such  conflicts  could  result  in a  rejection  of  our  or  our
licensors'  applications or the  invalidation of the patents.  This could have a
material adverse effect on our competitive position. If such conflicts occur, or
if we believe that such products may infringe on our proprietary  rights, we may
pursue  litigation or other  proceedings,  or may be required to defend  against
such  litigation.   Such   proceedings  may  materially   adversely  affect  our
competitive  position,  and we may not be  successful  in any  such  proceeding.
Litigation and other proceedings can be expensive and time consuming, regardless
of  whether  we  prevail.  This  can  result  in the  diversion  of  substantial
financial,  managerial  and other  resources from other  activities.  An adverse
outcome could subject us to significant  liabilities to third parties or require
us to cease any related  research and  development  activities or product sales.
Some of the risks and uncertainties include:

     *    We  do  not  have  contractual   indemnification  rights  against  the
          licensors of the various drug patents;
     *    We may be required to obtain licenses under  dominating or conflicting
          patents or other proprietary rights of others;
     *    Such licenses may not be made available on terms  acceptable to us, if
          at all; and
     *    If we do not obtain such licenses,  we could encounter delays or could
          find that the development,  manufacture or sale of products  requiring
          such licenses is foreclosed.

     We also seek to protect our proprietary technology and processes in part by
confidentiality  agreements  with  our  collaborative  partners,  employees  and
consultants.  These  agreements  could be breached and we may not have  adequate
remedies  for any  breach.  Also,  our  trade  secrets  may  become  known or be
independently discovered by competitors. Certain research activities relating to
the  development of certain  patents owned by or licensed to us were funded,  in
part,  by  agencies  of the United  States  Government.  When the United  States
Government  participates in research activities,  it retains certain rights that
include the right to use the resulting  patents for government  purposes under a
royalty-free license.

     We also rely upon unpatented  trade secrets,  and no assurance can be given
that others will not independently develop substantially  equivalent proprietary
information  and  techniques,  or otherwise  gain access to our trade secrets or
disclose such technology,  or that we can meaningfully protect its rights to its
unpatented trade secrets and know-how.

DEPENDENCE UPON KEY PERSONNEL AND CONSULTANTS

     Our success  will depend in large part on our ability to attract and retain
highly qualified  scientific,  management and other personnel and to develop and
maintain  relationships with leading research  institutions and consultants.  We
are highly  dependent upon principal  members of our management,  key employees,
scientific  staff  and  consultants  which  we may  retain  from  time to  time.
Competition for such personnel and  relationships is intense,  and we may not be
able to continue to attract and retain such  personnel.  Our  consultants may be
affiliated  with or  employed  by  others,  and some  have  consulting  or other
advisory  arrangements  with other  entities  that may  conflict or compete with
their obligations to us. Inventions or processes discovered by such persons will
not necessarily  become our property and may remain the property of such persons
or others.

DEPENDENCE UPON SUPPLIERS

     We depend on outside suppliers for certain raw materials and components for
our products.  Such raw materials or components may not continue to be available
to our standards or on acceptable  terms, if at all, and  alternative  suppliers
may not be available to us on acceptable terms, if at all.  Further,  we may not
be able to adequately  produce needed materials or components  in-house.  We are
currently dependent on single,  contracted sources for a couple of key materials
or  services  used by us in our drug  development,  light  producing  and  light
delivery device development and production operations.  Although most of our raw
materials and components are available  from various  sources,  we are currently
developing  qualified backup  suppliers for each of these resources.  We have or
will  enter  into  agreements  with  these  suppliers,  which  may or may not be
successful or which may encounter delays or other problems, which may materially
adversely affect our business.

ENVIRONMENTAL MATTERS

     We are subject to  federal,  state,  county and local laws and  regulations
relating to the protection of the environment. In the course of our business, we
are  involved in the  handling,  storage  and  disposal  of  materials  that are
classified  as  hazardous.  Our safety  procedures  for  handling,  storage  and
disposal of such  materials  are  designed to comply  with  applicable  laws and
regulations.  However,  we may be involved in contamination or injury from these
materials.  If this occurs, we could be held liable for any damages that result,
and any such liability could  materially and adversely  affect us. Further,  the
cost of complying with these laws and regulations may increase materially in the
future.

YEAR 2000

     The Year 2000 issue is the result of computer  programs being written using
two  digits  rather  than four to  define  the  applicable  year.  Our  computer
equipment   and  software  and  devices  with  embedded   technology   that  are
time-sensitive  may recognize a date using "00" as the year 1900 rather than the
year 2000.  This could  result in a system  failure or  miscalculations  causing
disruptions of operations, such as:

     *    A  temporary  inability  to  process  accounting,  payroll,  database,
          network and software transactions;
     *    Possible disruption of environmental,  lighting, security controls and
          other corporate equipment;
     *    A temporary  inability to process clinical and preclinical testing and
          data; and
     *    Loss of telephone  and related  voicemail  and internet  messages,  in
          addition to other similar normal business activities.

     We have undertaken various initiatives intended to ensure that our computer
equipment and software will function  properly with respect to dates in the Year
2000 and thereafter. The term "computer equipment and software" includes systems
that are commonly thought of as information technology or IT systems,  including
accounting,  data processing and telephone/PBX  systems and other  miscellaneous
systems.  It also  includes  systems  that  are not  commonly  thought  of as IT
systems, such as alarm systems, fax machines, air conditioning units, internally
developed software and other  miscellaneous  systems.  Based upon our efforts to
date, we believe that certain of the computer  equipment and software we use may
require  replacement  or  modification.  Utilizing  both  internal  and external
resources  to identify  and assess  needed Year 2000  remediation,  we currently
anticipate  that our  Year  2000  identification,  assessment,  remediation  and
testing  efforts,  which began in February 1998, will be completed by August 31,
1999. We estimate that as of June 30, 1999, we had completed  approximately  90%
of the initiatives that we believe will be necessary to fully address  potential
Year 2000 issues relating to our computer equipment software and non-IT systems.
The projects  comprising the remaining 10% of the initiatives are in process and
are expected to be completed on or about August 31, 1999.  The  following  table
describes the Year 2000  initiatives as well as our progress and the anticipated
completion dates as of June 30, 1999:

</TABLE>

     We are in the process of  communicating  with our  significant  vendors and
service  providers  and  strategic  partners  to  determine  the extent to which
interfaces with such entities are vulnerable to Year 2000 issues and whether the
products and services  utilized by such entities are Year 2000  compliant.  This
process is expected to be completed in August 1999.


     We believe that the cost of our Year 2000  efforts,  as well as those costs
related to Year 2000 issues of third parties,  will approximate  $250,000. As of
June 30, 1999,  we had not incurred any external  costs related to our Year 2000
efforts.  Other  non-Year  2000 IT efforts have not been  materially  delayed or
impacted by Year 2000 initiatives. We presently believe that the Year 2000 issue
will not pose significant operational problems for us. However, if all Year 2000
issues are not properly identified, the Year 2000 issue may materially adversely
impact our results of  operations  or adversely  affect our  relationships  with
vendors,  or others.  Additionally,  the Year 2000 issues of other  entities may
have a material adverse impact on our systems or results of operations.


VOLATILITY OF STOCK PRICE

     The market  prices for our common  stock,  and the  securities  of emerging
pharmaceutical  and medical  device  companies,  have  historically  been highly
volatile and subject to extreme  price  fluctuations,  which may have a material
adverse  effect  on  the  market  price  of  the  common  stock.  Extreme  price
fluctuations could be the result of the following:

     *    Future   announcements   concerning  Miravant  or  our  collaborators,
          competitors or industry;
     *    The  results  of  our  testing,   technological   innovations  or  new
          commercial products;
     *    The achievement of or failure to achieve certain milestones; and
     *    Governmental regulations, rules and orders, or developments concerning
          safety of our products.

     In addition,  the stock  market has  experienced  extreme  price and volume
fluctuations.  This volatility has  significantly  affected the market prices of
securities  of many emerging  pharmaceutical  and medical  device  companies for
reasons  frequently  unrelated or  disproportionate  to the  performance  of the
specific  companies.  These broad market  fluctuations may materially  adversely
affect the market price of our common stock.

CONTROL BY OFFICERS AND DIRECTORS

     As  of  July  15,  1999,  our  officers  and  directors   beneficially  own
approximately  5.51% of our outstanding  common stock  (approximately  16.83% is
beneficially  owned if all options granted to such officers and directors become
vested  and  are  exercised).  These  shareholders  will  have  the  ability  to
significantly  influence us and the direction of our business and affairs.  Such
concentration  of  ownership  may have the effect of  delaying or  preventing  a
change in control of Miravant, which could adversely affect the market price for
the common stock.

OUTSTANDING OPTIONS AND WARRANTS

     As of July 15, 1999, there were outstanding  options to purchase  2,802,691
shares of our common stock at a weighted  average  exercise  price of $18.05 per
share,  and warrants to purchase  4,031,928 shares of common stock at a weighted
average  exercise  price of $25.49 per share.  The exercise of these options and
warrants  would  result in  significant  book  value and  earnings  dilution  to
existing shareholders.

SHARES ELIGIBLE FOR FUTURE SALE

     Sales of  common  stock  in the  public  market  following  this  offering,
pursuant  to Rule  144  under  the  Securities  Act,  or upon  the  exercise  of
outstanding  options or warrants under Rule 701 or pursuant to our  registration
statements on Form S-8, could  materially  adversely  affect  prevailing  market
prices and may have a material  and  adverse  effect on our ability to raise the
capital necessary to fund our future operations.  Additionally,  certain holders
of shares of common stock are entitled to have their shares  registered for sale
under the  Securities  Act by us under  certain  circumstances.  The exercise of
these rights and the sale of such shares could have a material adverse effect on
the market price for the common stock.

                                 USE OF PROCEEDS

     Miravant  will not receive any of the proceeds  from the sale of the Shares
by the Selling  Shareholders,  but will receive the exercise prices payable upon
the exercise of the Warrants,  if exercised for cash. Any proceeds received form
the  exercise  of the  Warrants  will be used for  working  capital  and general
corporate purposes.


                              SELLING SHAREHOLDERS

     The following  table sets forth  information  with respect to the number of
Shares  beneficially  owned by each of the Selling  Shareholders,  the number of
Shares that may be offered hereby by each Selling  Shareholder and the number of
shares of common stock to be owned after the  offering,  assuming all the Shares
offered hereby are sold to persons not affiliated with the Selling Shareholders.
Pharmacia  &  Upjohn,  Inc.,  including  its  wholly  owned  subsidiaries,  is a
collaborative  partner of Miravant  and  beneficially  owns 11.00% of our common
stock. None of the other Selling Shareholders,  has, or in the past has had, any
other position,  office or relationship  with Miravant (other than as a security
holder) or any of its  affiliates.  As of July 15,  1999  there were  18,006,300
shares of our common stock issued and outstanding.

     Of the  Shares  set  forth  below as  beneficially  owned  and  offered  by
Pharmacia & Upjohn Treasury  Services AB, 360,000 represent Shares issuable upon
the exercise of Warrants  issued or to be issued to Pharmacia & Upjohn  Treasury
Services AB in connection with our Credit Agreement  entered into with Pharmacia
& Upjohn  Treasury  Services  AB in January  1999.  Of those  Warrants,  120,000
Warrants have been issued,  are vested and have been priced at an exercise price
of $11.87 per share. The remaining 240,000 Warrants,  when issued to Pharmacia &
Upjohn  Treasury  Services AB under the terms of the Credit  Agreement,  will be
exercisable  at price  equal to 140% of the  average  closing  bid prices of the
common stock for the ten (10) trading days  immediately  preceding the borrowing
request of the related loan and expire five years from the date of issuance. The
Shares  issuable upon the exercise of the 240,000  Warrants are not deemed to be
beneficially owned by Pharmacia & Upjohn or its subsidiaries under Rule 13d-3 of
the Exchange Act. The Registration  Rights Agreement requires us to register all
the shares  underlying  the  Warrants.  The Shares being  offered by Pharmacia &
Upjohn Treasury  Services AB include  additional Shares that may become issuable
pursuant  to the  terms of the  Warrants,  as such  number  may be  adjusted  in
accordance with Rule 416.

     With respect to the other three Selling Shareholders, 499,000 of the shares
of common stock set forth below  represent  shares issuable upon the exercise of
warrants issued to those Selling Shareholders in October 1997 in connection with
our  October  1997  private  placement  offerings.  Of those  warrants,  50% are
exercisable at $55.00 per share and 50% are exercisable at $60.00 per share, and
all expire on December 25, 2001. The 499,000  shares  issuable upon the exercise
of those  warrants and the 499,000 other shares of common stock set forth in the
table below with  respect to those  Selling  Shareholders  are the subject of an
earlier registration  statement we filed on Form S-3 and are not offered by this
prospectus.

                              PLAN OF DISTRIBUTION

     The Shares  may be sold from time to time by the  Selling  Shareholders  or
their pledgees or donees. See "Selling Shareholders." Those sales may be made on
the Nasdaq or in negotiated transactions, at prices and on terms then prevailing
or at prices related to the then current  market price or at negotiated  prices.
The methods by which the Shares may be sold may include, but are not limited to,
the following:

     *    Blocktrades  in which the  broker or dealer  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 or dealer as principal  and resale by the broker
          or dealer for its account;
     *    Ordinary  brokerage  transactions and transactions in which the broker
          solicits purchasers;
     *    Privately negotiated transactions;
     *    Short sales; and
     *    A combination of any these methods of sale.

In effecting sales,  brokers or dealers engaged by the Selling  Shareholders may
receive  commissions  or  discounts  from the Selling  Shareholders  or from the
purchasers in amounts to be negotiated immediately prior to the sale.

     Miravant has agreed to maintain the  effectiveness  of the  registration of
the Shares offered by this  prospectus  until the earlier of the date upon which
all of the Shares have been sold without  restriction on resale,  or the date on
which the Shares offered by this prospectus,  in the opinion of counsel,  may be
immediately sold by the Selling Shareholders without registration or restriction
on resale.  We cannot ensure that the Selling  Shareholders will sell any or all
of the Shares offered by this prospectus.

     Miravant is bearing all of the costs  relating to the  registration  of the
Shares.  Any 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 will be borne by the Selling Shareholders.  Miravant will not receive any
of the proceeds from this offering,  but will receive the exercise price payable
upon the exercise of the Warrants, if the Warrants are exercised for cash.

     Pursuant  to the  registration  rights  granted  to  some  of  the  Selling
Shareholders, we have agreed to indemnify those Selling Shareholders, any person
who controls those Selling Shareholders,  and any underwriters for those Selling
Shareholders, against specified 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  and  the  Exchange  Act.  The  Selling
Shareholders  and any  brokers  participating  in the sales of the Shares may be
deemed  to be  underwriters  within  the  meaning  of the  Securities  Act.  Any
commissions paid or any discounts or concessions allowed to any broker,  dealer,
underwriter,  agent or market  maker and,  if any broker,  dealer,  underwriter,
agent or market  maker  purchases  any of the Shares as  principal,  any profits
received  on the  resale  of those  Shares,  may be  deemed  to be  underwriting
commissions or discounts under the Securities Act.

                                  LEGAL MATTERS

     The validity of the issuance of the Shares of common stock  offered by this
prospectus  has been passed  upon for  Miravant  by Nida & Maloney,  LLP,  Santa

Item 15. Indemnification of Directors and Officers.

     Section  102(b)(7) of the Delaware  General  Corporation Law (the "Delaware
Law") permits a corporation to provide in its certificate of incorporation  that
directors of the corporation  shall not be personally  liable to the corporation
or its  shareholders  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 corporation or its  shareholders,  (ii) for acts or omissions not
in good faith or which involve intentional  misconduct or a knowing violation of
law, (iii) for payments of unlawful  dividends or unlawful stock  repurchases or
redemptions,  or (iv) for any  transaction  from which the  director  derived an
improper personal benefit. The Company's  Certificate of Incorporation  contains
such a provision.

     Section 145 of the Delaware Law provides that a  corporation  may indemnify
directors  and  officers  as well as other  employees  and  individuals  against
expenses  (including  attorneys'  fees),  judgments,  fines and amounts  paid in
settlement in connection with specified actions,  suits or proceedings,  whether
civil, criminal,  administrative or investigative (other than an action by or in
the right of the corporation a "derivative action"), if they acted in good faith
and in a manner  they  reasonably  believed  to be in or not opposed to the best
interests  of the  corporation,  and,  with  respect to any  criminal  action or
proceeding,  had no reasonable  cause to believe  their conduct was unlawful.  A
similar  standard is applicable in the case of derivative  actions,  except that
indemnification only extends to expenses (including attorneys' fees) incurred in
connection with defense or settlement of such action,  and the statute  requires
court approval before there can be any indemnification  where the person seeking
indemnification  has been found liable to the corporation.  Under Section 145, a
corporation  shall indemnify an agent of the  corporation for expenses  actually
and  reasonably  incurred if and to the extent such person was successful on the
merits in a proceeding or in defense of any claim, issue or matter therein.

     The  Registrant  is  presently  subject to Section  2115 of the  California
Corporations Code (the "California Code"), according to which Section 317 of the
California Code applies to the  indemnification of officers and directors of the
Registrant.   Under   Section   317  of   the   California   Code,   permissible
indemnification  by a corporation of its officers and directors is substantially
the same as permissible  indemnification  under Section 145 of the Delaware Law,
except that (i)  permissible  indemnification  does not cover actions the person
reasonably  believed were not opposed to the best interests of the  corporation,
as opposed to those the person  believed  were in fact in the best  interests of
the corporation, (ii) the Delaware Law permits advancement of expenses to agents
other than officers and directors  only upon approval of the board of directors,
(iii) in a case of stockholder approval of indemnification,  the California Code
requires certain minimum votes in favor of such indemnification and excludes the
vote of the potentially  indemnified  person,  and (iv) the California Code only
permits independent counsel to approve  indemnification if an independent quorum
of directors is not obtainable,  while the Delaware Law permits the directors in
any circumstance to appoint counsel to undertake such determination.

     The  Registrant  in its  Bylaws has  provided  for  indemnification  of its
officers, directors,  employees and other agents substantially identical to that
permitted under the California Code. Section 145 of the Delaware Law and Section
317 of the  California  Code  provide  that  they  are not  exclusive  of  other
indemnification  that  may  be  granted  by  a  corporation's  charter,  bylaws,
disinterested  director  vote,  shareholder  vote,  agreement or otherwise.  The
limitation  of  liability   contained  in  the   Registrant's   Certificate   of
Incorporation  and the  indemnification  provision  included in the Registrant's
Bylaws  are  consistent  with  Delaware  Law  Sections  102(b)(7)  and 145.  The
Registrant has also entered into separate  indemnification  agreements  with its
directors and officers that could require the Registrant, among other things, to
indemnify  them against  certain  liabilities  that may arise by reason of their
status or service as  directors  and  officers  and to  advance  their  expenses
incurred as a result of any  proceeding  against  them as to which they could be
indemnified,  including  liabilities  that may arise under the Securities Act of
1933. In addition, the Company has purchased directors and officers insurance.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be  permitted  to  directors,  officers or persons  controlling  the
Company pursuant to such  provisions,  the Company has been informed that in the
opinion of the  Securities  and  Exchange  Commission  such  indemnification  is
against public policy as expressed in such Act and is therefore unenforceable.

Item 17. Undertakings.

     (a)  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)(2) of the
               Securities Act of 1933;

          (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.
               Notwithstanding the foregoing, any increase or decrease in volume
               of  securities  offered (if the total dollar value of  securities
               offered  would not  exceed  that  which was  registered)  and any
               deviation  from  the low or  high  end of the  estimated  maximum
               offering  range may be reflected in the form of prospectus  filed
               with the Commission pursuant to Rule 424(b) if, in the aggregate,
               the  changes  in volume  and price  represent  no more than a 20%
               change in the maximum  aggregate  offering price set forth in the
               "Calculation  of   Registration   Fee"  table  in  the  effective
               registration statement;

          (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;

                  Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do
                  not apply if the  information  required  to be  included  in a
                  post-effective  amendment by those  paragraphs is contained in
                  periodic  reports filed by the Registrant  pursuant to Section
                  13 or Section  15(d) of the  Securities  Exchange  Act of 1934
                  that  are   incorporated  by  reference  in  the  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.

     (b)  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
          (and,  where  applicable,  each filing of an employee  benefit  plan's
          annual report pursuant to Section 15(d) of the Securities Exchange Act
          of  1934)  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.

     (c)  Insofar  as   indemnification   for  liabilities   arising  under  the
          Securities  Act of 1933 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 Securities and Exchange Commission such indemnification
          is against  public policy as expressed in the  Securities  Act of 1933
          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 Securities Act of 1933
          and will be governed by the final adjudication of such issue.


                                   SIGNATURES

     Pursuant to the  requirements of the Securities Act of 1933, the Registrant
certifies  that it has  reasonable  grounds to believe  that it meets all of the
requirements  for  filing  on Form S-3 and has  duly  caused  this  Registration
Statement  to be  signed  on its  behalf  by  the  undersigned,  thereunto  duly
authorized, in the City of Santa Barbara, State of California, on July 29, 1999.

         Re:      Registration Statement on Form S-3

Ladies and Gentlemen:

     We have examined the  Registration  Statement on Form S-3 filed by you with
the Securities and Exchange  Commission (the  "Commission") on or about July 29,
1999 (as such may be amended or supplemented,  the "Registration Statement"), in
connection  with the  registration  under the Securities Act of 1933, as amended
(the "Act"), of up to 3,856,710 shares of your Common Stock (the "Shares").  The
Shares,  which include up to 360,000 shares of Common Stock issuable pursuant to
exercise of warrants, are to be sold by the Selling Shareholders as described in
such Registration  Statement.  All of the Shares being sold were or will be sold
by the  Company  to the  Selling  Shareholders  and will be sold by the  Selling
Shareholders to the public. As counsel in connection with this  transaction,  we
have examined the proceedings proposed to be taken by you in connection with the
issuance and sale of the Shares.

     Based  on the  foregoing,  it is our  opinion  that  the  registration  and
issuance  of the Shares has been duly  authorized  and that the Shares that have
been issued are legally and validly issued,  fully paid and  non-assessable  and
that, upon  conclusion of the proceedings  being taken or contemplated by us, as
your  counsel,  to be taken prior to the  issuance of the Shares  issuable  upon
exercise of the  warrants,  the Shares  issuable  upon exercise of the warrants,
when  issued and sold in the manner  described  in the  Registration  Statement,
including  payment of the exercise  price for the warrants,  will be legally and
validly issued, fully paid and non-assessable.

     We  consent to the use of this  opinion  as an exhibit to the  Registration
Statement and further  consent to the use of our name wherever  appearing in the
Registration  Statement,  including the prospectus  constituting a part thereof,
which has been approved by us, as such may be further  amended or  supplemented,
or  incorporated  by reference  in any  Registration  Statement  relating to the
prospectus filed pursuant to Rule 462(b) of the Act.

                               Very truly yours,


                              /s/ Nida & Maloney, LLP
                              -----------------------
