                          MIRAVANT MEDICAL TECHNOLOGIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS



1.    Basis of Presentation

      The information contained herein has been prepared in accordance with Rule
      10-01 of Regulation  S-X. The  information  at March 31, 1998, and for the
      three month periods  ended March 31, 1998 and 1997,  is unaudited.  In the
      opinion of management,  the information reflects all adjustments necessary
      to make the results of operations for the interim periods a fair statement
      of such operations. All such adjustments are of a normal recurring nature.
      Interim results are not necessarily indicative of results for a full year.
      For  a  presentation  including  all  disclosures  required  by  generally
      accepted accounting principles,  these financial statements should be read
      in conjunction with the audited consolidated  financial statements for the
      year ended December 31, 1997 included in the Miravant Medical Technologies
      Annual  Report  on Form  10-K  filed  with  the  Securities  and  Exchange
      Commission.

2.    Notes Receivable from Officers

      In December  1997,  the  Compensation  Committee of the Board of Directors
      recommended  and  subsequently  approved an equity loan program in varying
      amounts for the Company's  Chief  Executive  Officer,  President and Chief
      Financial  Officer.  The notes,  which accrue  interest at a fixed rate of
      5.8% and are  payable in five years,  were  awarded  specifically  for the
      purpose of exercising  options to acquire the  Company's  Common Stock and
      for paying the related option exercise price and payroll taxes.  The notes
      are collateralized by the underlying shares acquired upon exercise.  As of
      March 31, 1998,  the loans had been fully utilized by each of the officers
      and the related notes have been classified as a reduction of shareholders'
      equity.

 3.   Commitments and Contingencies

      In February 1998, the Company agreed to guaranty a term loan in the amount
      of  $7,600,000  from a bank to a director of the Company.  The loan is due
      and  payable on July 31,  1999,  or sooner  upon an event of  default  (as
      defined in the loan  agreement),  bears  interest at the bank's  reference
      rate, minus .5% per annum, payable quarterly, and is collateralized by all
      of the director's shares of the Company's Common Stock. In connection with
      the  guaranty,  the  Company  granted  the bank a security  interest in an
      account  maintained at the bank and agreed,  upon an event of default,  to
      purchase  the loan from the bank for a price  generally  equal to the then
      outstanding principal, plus accrued interest, fees and costs. In the event
      the  Company  purchases  the loan,  the  director  granted the Company the
      option to acquire  all of his shares of Common  Stock at a price  equal to
      50% of the 20-day average closing price,  net of the loan  repayment.  The
      director also agreed to certain  restrictions  on the sale of such shares.
      Under the loan  agreement and the  guaranty,  the director and the Company
      are subject to the maintenance of specified financial and other covenants.
      In  conjunction  with the  guaranty of this loan,  the  director  paid the
      Company a  transaction  fee of  $152,000,  which was paid in shares of the
      Company's  Common  Stock and is  included  in other  income for the period
      ended March 31, 1998.

4.    Per Share Data

      The Company has adopted  Statement of Financial  Accounting  Standards No.
      128 "Earnings per Share" ("SFAS No.  128"),  which  supersedes  Accounting
      Principles  Board  Opinion No. 15 and which is  effective  for all periods
      ending after December 31, 1997. SFAS No. 128 replaced the  presentation of
      primary  and fully  diluted  earnings  per share  with  basic and  diluted
      earnings per share.  Unlike primary earnings per share, basic earnings per
      share excludes any dilutive  effects of options,  warrants and convertible
      securities.  Diluted  earnings per share is very similar to the previously
      reported  fully  diluted  earnings per share and  reflects  the  potential
      dilution that would occur if securities or other contracts to issue common
      stock were exercised or converted to common stock. Common stock equivalent
      shares  from stock  options  and  warrants  have been  excluded  from this
      computation  as  their  effect  is  antidilutive.  All  previously  stated
      earnings per share amounts conform to the new SFAS No. 128 requirements.

      Basic loss per common share for the quarters ended March 31, 1998 and 1997
      were  computed by dividing  the net loss by the  weighted  average  shares
      outstanding  during the period in accordance  with SFAS No. 128. Since the
      effect of the  assumed  exercise of stock  options  and other  convertible
      securities was antidilutive, basic and diluted loss per share as presented
      on the consolidated statements of operations are the same.

5.    New Accounting Pronouncements

      In June 1997, the Financial Accounting Standards Board issued Statement of
      Financial Accounting Standards No. 130, "Reporting  Comprehensive  Income"
      ("SFAS No. 130"). This statement  establishes  standards for reporting and
      display  of  comprehensive  income  and  its  components.   Components  of
      comprehensive  income are net income  and all other  non-owner  changes in
      equity such as unrealized gains on available-for-sale  securities that are
      not included in net income.  This  statement  requires that an enterprise:
      (a)  classify  items of other  comprehensive  income by their  nature in a
      financial  statement  and (b)  display  the  accumulated  balance of other
      comprehensive  income  separately  from  retained  earnings  in the equity
      section  of the  balance  sheet.  While  SFAS  No.  130 is  effective  for
      financial statements issued for periods beginning after December 15, 1997,
      it had no  material  impact on the  Company's  results  of  operations  or
      related disclosures for the three months ended March 31, 1998 and 1997.

      Financial Accounting Standards Board Statement No. 131, "Disclosures about
      Segments of an Enterprise and Related Information" ("SFAS No. 131"), which
      is also effective  beginning in 1998, requires the disclosure of financial
      information  on  operating  segments  on the basis used by  management  in
      evaluating  segment  performance  and deciding how to allocate  resources.
      While  the  Company  does not  anticipate  that  SFAS No.  131 will have a
      material impact on its financial  reporting and disclosures,  any changes,
      if any,  will first be reflected in the  Company's  1998 Annual  Report on
      Form 10-K.

6.   Subsequent Event

     In April 1998, the Company entered into a revolving  credit  agreement with
     its affiliate, Ramus Medical Technologies ("Ramus"),  pursuant to which the
     Company  shall  from  time to time  make  loans to  Ramus  in an  aggregate
     outstanding  principal amount not to exceed at any one time $2 million. The
     unpaid principal  amount of the loans,  which are to be used to fund Ramus'
     clinical  trial and operating  costs,  accrues  interest at a variable rate
     (7.35% as of March 31, 1998) based on the  Company's  bank rate and matures
     approximately  one and a half years  after the  completion  by Ramus of its
     first surgical implant in a human involving  coronary artery bypass surgery
     in a  formally  conducted  clinical  trial.  The loans are  evidenced  by a
     promissory  note, the balance of which shall be convertible  under  certain
     circumstances at the option of the Company into shares of Ramus stock. Upon
     the occurrence of specified  milestones,  the credit agreement provides for
     the issuance to the Chief Executive  Officer of Ramus a warrant to purchase
     10,000 shares of the Company's Common Stock. If issued, the warrant will be
     exercisable at a price  generally equal to the average closing price of the
     Common Stock over the twenty consecutive  trading days immediately prior to
     the date of  issuance.  As of April 30, 1998,  Ramus had borrowed  $500,000
     under the credit agreement.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
         CONDITION AND RESULTS OF OPERATIONS

         The  following  discussion  should  be read  in  conjunction  with  the
consolidated  financial  statements and notes thereto.  This Quarterly Report on
Form 10-Q may be deemed to include forward looking statements within the meaning
of Section 27A of the  Securities  Act of 1933 and Section 21E of the Securities
Exchange  Act of 1934 that involve risk and  uncertainty,  including  financial,
clinical, business environment and trend projections.  Although Miravant Medical
Technologies  (the  "Company")  believes  that  its  expectations  are  based on
reasonable  assumptions,  it can  give  no  assurance  that  its  goals  will be
achieved.  The  important  factors  that could  cause  actual  results to differ
materially from those in the forward looking statements herein include,  without
limitation, the early stage of development of both the Company and its products,
the timing and uncertainty of results of both research and regulatory processes,
the extensive government  regulation  applicable to the Company's business,  the
unproven  safety and efficacy of the  Company's  drug and device  products,  the
Company's  significant  additional  financing  requirements,  the uncertainty of
future capital funding, the highly competitive  environment of the international
pharmaceuticals  and medical  device  industries and the presence of a number of
competitors with significantly greater financial,  technical and other resources
and extensive operating  histories,  the Company's potential exposure to product
liability or recall,  uncertainties  relating to patents and other  intellectual
property,  including  whether the Company will obtain  sufficient  protection or
competitive advantage therefrom,  the Company's dependence upon a limited number
of key personnel and consultants,  the Company's  significant  reliance upon its
collaborative  partners for achieving its goals,  and other factors  detailed in
the Company's report on Form 10-K for the year ended December 31, 1997.

GENERAL

         Since its inception,  the Company has been  principally  engaged in the
research  and  development  of drugs  and  medical  device  products  for use in
PhotoPoint(TM), the Company's proprietary technologies for photodynamic therapy.
The  Company  has been  unprofitable  since  its  founding  and has  incurred  a
cumulative  net loss of  approximately  $88.8 million as of March 31, 1998.  The
Company expects to continue to incur substantial and increasing operating losses
for the next several years due to continued  and increased  spending on research
and development  programs,  the funding of preclinical and clinical  testing and
regulatory  activities  and  the  costs  of  manufacturing,   marketing,  sales,
distribution and administrative activities.

         The Company's revenues  generally  primarily reflect income earned from
licensing agreements,  contracts,  grants, and medical device products.  For the
quarter  ended March 31,  1998,  the  Company's  revenues  were  generated  from
clinical  reimbursements  and royalties from  licensing  agreements and revenues
from grants.  Device product sales represent limited sales of PhotoPoint devices
(e.g. light producing devices and light delivery and measurement devices),  sold
both domestically and internationally, to researchers and an OEM distributor. To
date,  the Company has received no revenue from the sale of drug  products,  and
the Company is not permitted to engage in  commercial  sales of drugs or devices
until  such  time,  if  ever,  as  the  Company  receives  requisite  regulatory
approvals.  As a result,  the  Company  does not  expect  to record  significant
product sales until such approvals are received.

         Until the Company  commercializes  its product(s),  the Company expects
revenues to continue to be  attributable  to  licensing  agreements,  contracts,
grants and device product sales for research use. The Company  anticipates  that
future   revenues   and  results  of   operations   may  continue  to  fluctuate
significantly  depending  on,  among  other  factors,  the timing and outcome of
applications  for regulatory  approvals,  the Company's  ability to successfully
manufacture,  market and distribute its drug products and device products and/or
the establishment of collaborative arrangements for the manufacturing, marketing
and distribution of some of its products.  The Company anticipates its operating
activities will result in substantial net losses for several more years.

         The Company is  currently  conducting  clinical  trials in oncology and
ophthalmology.  In dermatology,  the Company is continuing to perform additional
preclinical  studies  as  required  by the  Federal  Drug  Administration  (FDA)
Division  of  Dermatology  for the non  life-threatening  disorder of basal cell
carcinoma  (BCC).  Based  upon  an  evaluation  of all the  criteria  of the FDA
Division of Dermatology and various economic and development factors,  including
cost,  reimbursement,  the available alternative therapies for this disorder and
the development of topical and other  formulations for its PhotoPoint drugs, the
Company may or may not elect to further develop PhotoPoint procedures for BCC.

         The Company has  awarded,  and may award in the future,  stock  options
that vest upon the achievement of certain milestones.  Under APB Opinion No. 25,
such options are accounted for as variable  stock  options.  As such,  until the
milestone is achieved (but only after it is determined to be probable), deferred
compensation  is recorded in an amount equal to the difference  between the fair
market  value of the Common Stock on the date of  determination  less the option
exercise  price and is adjusted from period to period to reflect  changes in the
market  value of the Common  Stock.  Deferred  compensation,  as it relates to a
particular  milestone,  is amortized over the period between when achievement of
the  milestone  becomes  probable  and when the  milestone  is  estimated  to be
achieved.  Amortization  of deferred  compensation  could result in  significant
additional  compensation  expense being  recorded in future periods based on the
market value of the Common Stock from period to period.

         Effective  June 21, 1996,  the  Compensation  Committee of the Board of
Directors  adjusted the future  vesting  periods of the variable  stock  options
covering  400,000  shares of Common  Stock.  These  variable  stock options were
adjusted  to change  the  vesting  periods to  specific  dates as opposed to the
original vesting periods which were based upon the achievement of milestones; no
change was made to the exercise  prices of these variable  stock  options.  This
change in the vesting  periods  provides for the options to be accounted  for as
non-variable   options  and   therefore   alleviates   the  impact  of  deferred
compensation  fluctuating  in future  periods  based on changes in the per share
market  value from  period to period.  As of March 31,  1998,  options  covering
302,500  shares  with an  exercise  price of $34.75  per share  have  vested and
options covering 75,000 shares have been canceled. The remaining unvested shares
will vest in the years 1998 through 2000.

RESULTS OF OPERATIONS

         The following  table  provides a summary of the Company's  revenues for
the three months ended March 31, 1998 and 1997:

</TABLE>

         REVENUES. For the three months ended March 31, 1998, revenues increased
to  $635,000  from  $291,000  for the three  months  ended March 31,  1997.  The
increase  is related to an increase  in license  revenues  to  $445,000  for the
period from $225,000 for the same period in 1997. License revenue represents the
billing for the specific reimbursement of clinical costs in conjunction with the
license  agreement  entered  into in July 1995  with  Pharmacia  & Upjohn,  Inc.
("Pharmacia & Upjohn").  Additionally, the Company recorded revenues of $141,000
associated with two on-going grants  initially  received in the third quarter of
1997.  There were no active  grants or grant revenue  recorded  during the first
three months of 1997. The Company  anticipates  recording license income for the
specific  reimbursement  of clinical  costs  throughout  1998. The level of such
license,  grant and royalty income is likely to fluctuate materially from period
to period and in the future  depending on the amount of clinical  costs incurred
and/or reimbursed and the extent of development activities under the Pharmacia &
Upjohn  license  agreement,  the amount of grant income awarded and expended and
the  amount  of  device  products  sold by  Laserscope,  pursuant  to a  license
agreement  entered into in 1992 which  provides  royalties  from the sale of the
Company's previously designed device products.

         COST OF GOODS SOLD.  Reflective of the  Company's  decision to allocate
its  manufacturing  resources to supporting its preclinical and clinical testing
and decrease in custom device order activity, the Company did not incur any cost
of goods sold for the three months ended March 31, 1998 and March 31, 1997.  The
Company expects gross margins to be  insignificant  until the Company  commences
commercial sales of its products.

         RESEARCH  AND  DEVELOPMENT.  The  Company's  research  and  development
expenses  for the three  months  ended March 31, 1998  increased to $6.3 million
from $3.9 million for the three  months  ended March 31,  1997.  The increase in
research and development expenses relates primarily to costs associated with the
screening  and  treatment  of qualified  individuals  for  participation  in the
clinical  trials,  the preparation for the Company's first New Drug  Application
(NDA) filing for cutaneous metastatic breast cancer, currently anticipated to be
filed in 1998,  and the  preclinical  work  associated  with the  development of
existing and new compounds,  formulations  and clinical  programs.  In addition,
research and development  expenses  continue to increase in conjunction with the
Company's  progression  through the various stages of  preclinical  and clinical
trials and the increased costs associated with the purchase of raw materials and
supplies  for the  production  of clinical  devices and drug  product for use in
these preclinical and clinical trials.  The Company  anticipates future research
and development expenses to increase as the Company continues to prepare for its
NDA filing and expands its research and development programs, which includes the
increased  hiring of  personnel  and  continued  expansion  of  preclinical  and
clinical testing. See "--General."

         SELLING, GENERAL AND ADMINISTRATIVE. The Company's selling, general and
administrative  expenses for the three months ended March 31, 1998  increased to
$3.0  million  from $2.3  million for the three  months  ended  March 31,  1997.
Selling,  general and administrative  costs increased for the first three months
of 1998 as compared  to the same period in 1997 as a result of (i) the  increase
in  costs  associated  with   professional   services  received  from  financial
consultants,  attorneys,  and public and media  relations  and (ii)  payroll and
overhead costs due to the addition of  administrative  and corporate  personnel.
The Company  expects  future  selling,  general and  administrative  expenses to
continue to grow as a result of the increased  support required for research and
development  activities,   continuing  corporate  development  and  professional
services,  compensation  expense  associated  with stock  options and  financial
consultants  and  general  corporate  matters,  as  well  as the  other  factors
described above.

         LOSS IN INVESTMENT  IN AFFILIATE.  For the three months ended March 31,
1998  and  1997,  the  Company   recorded  as  expense  $454,000  and  $232,000,
respectively, in connection with its investment in Ramus Medical Technologies in
December 1996. The amounts recorded represent the full amount of the affiliate's
losses for the quarters  ended March 31, 1998 and 1997. The  affiliate's  losses
from operations are expected to be ongoing  throughout 1998 and beyond,  and the
level of such  losses are  expected  to  fluctuate  depending  on  research  and
development activities and preclinical and clinical trial progress.

         INTEREST AND OTHER  INCOME.  For the three months ended March 31, 1998,
net interest and other income increased to $1.3 million compared to net interest
and other income of $634,000  for the three  months  ended March 31,  1997.  The
increase in net interest and other income resulted primarily from the investment
of proceeds  received from the Company's  private  equity  offering in September
1997.  Additionally,  the Company also  recorded as other  income  $152,000 as a
transaction  fee  for  the  guaranty  of a loan  to one  of its  directors.  The
transaction fee was paid in the form of the Company's Common Stock which will be
retired.
         The Company does not believe that  inflation has had a material  impact
on its results of operations.


LIQUIDITY AND CAPITAL RESOURCES

         Since  inception  through March 31, 1998, the Company has accumulated a
deficit  of  approximately  $88.8  million  and  expects  to  continue  to incur
substantial  and increasing  operating  losses for the next several  years.  The
Company has financed its  operations  primarily  through  private  placements of
common and preferred stock,  private  placements of convertible  notes and short
term notes, its initial public offering, Pharmacia & Upjohn's purchase of Common
Stock and a secondary  public  offering.  As of March 31, 1998,  the Company had
received  proceeds from the sale of equity  securities and convertible  notes of
approximately $181.5 million. The Company has available a $1.0 million bank line
of credit which has a variable rate of interest based on the bank's lending rate
(7.35%  as of March 31,  1998),  which  expires  on  January  31,  1999,  and is
collateralized by the Company's cash balances. The credit agreement subjects the
Company  to certain  customary  restrictions,  including  a  prohibition  on the
payment of dividends.  The Company presently has no outstanding borrowings under
the bank line of credit.

         In connection with the licensing agreement with Pharmacia & Upjohn, the
Company has recorded as license  income the  reimbursement  of clinical costs of
$445,000  for the three months  ended March 31,  1998.  The Company  anticipates
recording  license  income for the  specific  reimbursement  of  clinical  costs
throughout the remainder of 1998.

         For the first  three  months of 1998,  the  Company  required  cash for
operations of  approximately  $8.5 million compared to $6.0 million for the same
period in 1997.  The increase in cash used in operations was primarily due to an
increase in operating  activities  associated  with the  continued  expansion of
preclinical  and clinical  testing,  the  increase in research  and  development
programs and  personnel,  the reduction of accounts  payable and the increase in
general  corporate  activities.  For the first three months of 1998, the Company
required cash from its financing  activities  of  approximately  $7.5 million as
compared to net cash received from financing activities of $266,000 for the same
period in 1997.  The increase in cash used in financing  activities is primarily
related  to the  repurchase  made by the  Company  of its  Common  Stock and the
issuance of the executive equity loans during the first three months of 1998.

         The  Company  invested  a total of  $653,000  in  property,  plant  and
equipment  during the first three months of 1998 compared to $122,000 during the
same  period  in 1997.  During  1996,  the  Company  entered  into two new lease
agreements  for  additional  facilities.  The  addition of these new  facilities
increased the Company's equipment costs due to the expansion of its laboratories
and office space and the purchase of equipment  for this new space.  The Company
expects to continue  to purchase  property  and  equipment  in the future as the
Company  expands  its   preclinical,   clinical  and  research  and  development
activities.  Since  inception,  the  Company  has  entered  into  capital  lease
agreements  for  approximately  $184,000 of equipment,  consisting  primarily of
laboratory  equipment.  The Company  expects to continue to lease equipment from
time to time as needed,  when and if  financing  resources  become  available at
acceptable terms to the Company.

         The  Company's  capital  funding  requirements  will depend on numerous
factors,  including  the progress and  magnitude of the  Company's  research and
development  programs  and  preclinical  testing and clinical  trials,  the time
involved in  obtaining  regulatory  approvals,  the cost  involved in filing and
maintaining  patent  claims,  technological  advances,   competitor  and  market
conditions,  the ability of the Company to establish and maintain  collaborative
arrangements,  the cost of manufacturing scale-up and the cost and effectiveness
of commercialization activities and arrangements.

         The Company may require  substantial  funding to continue  its research
and development activities,  preclinical and clinical testing and manufacturing,
marketing,  sales, distribution and administrative  activities.  The Company has
raised funds in the past through the public or private sale of  securities,  and
may  contemplate   raising  funds  in  the  future  through  public  or  private
financings,  collaborative  arrangements  or from other sources.  The success of
such  efforts  will  depend in large part upon  continuing  developments  in the
Company's  preclinical and clinical  testing.  The Company  continues to explore
and, as appropriate,  enter into discussions with other companies  regarding the
potential for equity investment,  collaborative arrangements, license agreements
or  development  or other  funding  programs  with the Company in  exchange  for
manufacturing,  marketing, distribution or other rights to products developed by
the Company.  However,  there can be no assurance  that  discussions  with other
companies will result in any investments, collaborative arrangements, agreements
or funding,  or that the necessary  additional  financing through debt or equity
financing  will be  available  to the Company on  acceptable  terms,  if at all.
Further,  there can be no assurance that any  arrangements  resulting from these
discussions will  successfully  reduce the Company's  funding  requirements.  If
additional funding is not available to the Company when needed, the Company will
be required to scale back its research and development programs, preclinical and
clinical testing and  administrative  activities and the Company's  business and
financial results and condition would be materially adversely affected.

     collectively referred to as the "Collateral"):

     A.   Market Value Savings.  The following  described  Market Value Savings:
          0734-16600  together  with  all  substitutions  thereof  and  with all
          interest accruing thereunder and therefrom.

     B.   Monies and Other Property in Possession. In addition to the above, all
          monies, and property of the Grantor now or hereafter in the possession
          of the Bank or the Bank's agents, or any one of them,  including,  but
          not limited to, all deposit accounts, certificates of deposit, stocks,
          bonds,  indentures,   warrants,   options  and  other  negotiable  and

     guarantied.  The indebtedness and obligations  secured hereby  (hereinafter
     referred to as the "Indebtedness") shall include any and all modifications,

required  under any consumer  protection  law  (including but not limited to the
Truth in Lending Act) or any  regulation  thereto,  as now existing or hereafter
amended, is or has been given.

3.   Grantor's  Representations  and  Warranties.  The Grantor  hereby makes the

     and warranties are continuing:

          necessary  to  maintain  the  Grantor's  rights  and  privileges,  has

          required  hereunder have been duly authorized and do not and will not:
          (i) violate any provision of any law, rule, regulation, writ, judgment
          or injunction presently in effect affecting the Grantor;  (ii) require

          of the articles of incorporation  or by-laws of the Grantor;  or (iii)
          result  in a breach of or  constitute  a  default  under any  material
          agreement  to which the  Grantor is a party or by which the  Grantor's
          properties may be bound or affected.

     C.   Legal Effect. This Security Agreement  constitutes,  and any document,
          instrument  or  agreement   required  hereunder  when  delivered  will
          constitute,  legal,  valid  and  binding  obligations  of the  Grantor
          enforceable  against the Grantor in accordance  with their  respective
          terms.

     D.   Fictitious  Trade  Styles.  The Grantor  currently  uses no fictitious
          trade styles in connection with its business  operations.  The Grantor

          fictitious trade style at any future date,  indicating the trade style
          and state(s) of its use.

          securing the Indebtedness or other indebtedness owed to the Bank; (ii)
          liens for taxes,  assessments or similar charges either not yet due or
          being contested in good faith; (iii) liens of mechanics,  materialmen,

          security  interests which, as of the date hereof,  have been disclosed
          to and  approved  by the Bank in  writing;  and (vi)  those  liens and
          security interests which in the aggregate constitute an immaterial and
          insignificant  monetary  amount  with  respect to the net value of the
          Grantor's assets (collectively, the "Permitted Liens").

      F.  Financial Statements. All financial statements,  information and other
          data  now or  hereafter  submitted  to the  Bank  by  the  Grantor  in
          connection  with the  transaction  with respect to which this Security
          Agreement is entered into are true, accurate and correct and have been
          or will be prepared in accordance with generally  accepted  accounting
          principles  consistently applied.  Since the most recent submission of
          any such financial  statement,  information or other data to the Bank,
          the Grantor represents and warrants that no material adverse change in
          the financial  condition or operations as disclosed therein or thereby
          has  occurred  which  has not  been  fully  disclosed  to the  Bank in
          writing.

          there  are  no  actions,  suits  or  proceedings  pending  or,  to the
          knowledge of the Grantor,  threatened against or affecting the Grantor
          or the Grantor's properties before any court or administrative  agency
          which, if determined  adversely to the Grantor,  would have a material
          adverse effect on the Grantor's financial condition, operations or the
          Collateral.

      H.  Taxes.  The Grantor has filed all tax returns required to be filed and
          paid  all  taxes  shown  thereon  to be due,  including  interest  and
          penalties,  other  than  taxes  which are  currently  payable  without
          penalty or interest or those  which are being duly  contested  in good
          faith.


4.   Grantor's Covenants. The Grantor covenants and agrees that, unless the Bank
     otherwise consents in writing, the Grantor shall at all times:

      A.  Maintenance  of  Collateral.  Except  for  Permitted  Liens,  keep and
          maintain  the  Collateral  free  and  clear  of  all  levies,   liens,
          encumbrances and other security interests (including,  but not limited
          to, any lien of  attachment,  judgment  or  execution)  and defend the
          Collateral  against  any such  levy,  lien,  encumbrance  or  security
          interest; comply with all laws, statutes and regulations pertaining to
          the Collateral  and take such actions and execute such  agreements and
          other documents necessary to perfect, evidence and continue the Bank's
          security interest in the Collateral and the priority thereof.

      B.  Covenants  With  Respect to  Possessory  Collateral.  With  respect to
          Possessory  Collateral,  (which is defined to mean that portion of the
          Collateral  which  consists of  securities,  certificates  of deposit,
          savings or  checking  accounts,  notes and  instruments  and any other
          similar  collateral in which a security interest is normally perfected
          through  possession by the Bank or its agent),  the Grantor  covenants
          and agrees:

                   (i)   The  Possessory  Collateral  shall at all times be of a
                         character   and  value   acceptable  to  the  Bank,  as
                         determined  by  the  Bank  in  its  sole  and  absolute
                         judgment.

                   (ii)  The Grantor  shall not withdraw or seek to withdraw any
                         of the  Possessory  Collateral  now or hereafter in the
                         possession of the Bank or the Bank's agents.

                   (iii)   The Grantor shall make timely  payments of all taxes,
                           charges, liens and assessments against the Possessory
                           Collateral.

      C.  Reporting Requirements.  Promptly upon the Bank's request,  deliver or
          cause to be delivered to the Bank such  information  pertaining to the
          Grantor,  the  Collateral  or  such  other  matters  as the  Bank  may
          reasonably request.

      D.  Payment  of  Obligations.  Pay all of the  Grantor's  liabilities  and
          obligations when due.

      E.  Compensation  of Employees.  Compensate  the  Grantor's  employees for
          services  rendered  at an hourly  rate at least  equal to the  minimum
          hourly  rate  prescribed  by any  applicable  federal  or state law or
          regulation.

      F.  Possessory  Collateral  Loan-to-Value Ratio. The Grantor covenants and
          agrees  that  so long as all or any  part  of the  Indebtedness  shall
          remain   outstanding,   the  outstanding   principal  balance  of  the
          obligations secured by this Agreement shall at no time be greater than
          100.00% of the value of the Possessory  Collateral at its then current
          market value (as determined by the Bank) (the "Loan-to-Value Ratio").

      To the extent that such Possessory  Collateral  Loan-to-Value Ratio is not
      maintained,  the Grantor  shall  promptly,  upon the Bank's  request:  (i)
      assign  and  pledge to the Bank  such  additional  assets  of a  character
      satisfactory to the Bank and having a market value sufficient to reinstate
      and maintain such Possessory Collateral  Loan-to-Value Ratio, or (ii) make
      payment  to the Bank in an amount  sufficient  to reduce  the  outstanding
      principal  balance of the Indebtedness so that such Possessory  Collateral
      Loan-to-Value Ratio is reinstated and maintained.

      G.  Notices. Give the Bank prompt written notice of: (i) any change in the
          Grantor's  place of business or the acquisition of more than one place
          of business; (ii) any proposed or actual change in the Grantor's name,
          identity or business  nature;  (iii) any change in the location of any
          Collateral; (iv) any Event of Default; (v) litigation,  arbitration or
          administrative  proceedings  to which the Grantor is a party and which
          affects the  Collateral  and in which the claim or  liability  exceeds
          $5,000.00;  and (vi) any other  matter which has resulted in, or might
          result  in,  a  material  adverse  change  in  the  Collateral  or the
          financial condition or business operations of the Grantor.

5.   Bank's  Rights  Regarding  Possessory  Collateral.   With  respect  to  the
     Possessory  Collateral,  at its option and without any obligation to do so,
     the Bank may,  either in the name of the Bank,  the  Bank's  nominee or the
     Grantor:

     A.   Collect,  endorse and receive all sums including,  but not limited to,
          dividends,  and interest,  now or hereafter payable upon or on account
          of the Possessory Collateral.

     B.   Enter into any  agreement  relating  to or  affecting  the  Possessory
          Collateral  and,  in  connection  therewith,  the Bank  may  surrender
          control of any such Collateral,  accept other property in exchange for
          such  Collateral and do and perform such acts as it deems proper.  Any
          money or property  received in exchange for any such Collateral  shall
          be  subject  to and held by the  Bank  pursuant  to the  terms of this
          Security Agreement.

     C.   Make any  compromise  or  settlement  with  respect to the  Possessory
          Collateral that the Bank, in its sole and absolute  discretion,  deems
          proper.

     D.   Insure and do such other acts as the Bank deems necessary, in its sole
          discretion, to preserve or protect the Possessory Collateral.

     E.   Cause the  Possessory  Collateral to be transferred to the Bank's name
          or the name of the Bank's nominee.

     F.   With respect to the Possessory Collateral, exercise all rights, powers
          and remedies of an owner but excluding any voting rights.

6.   Events of Default.  Any one or more of the following described events shall
     constitute an event of default ("Event of Default") hereunder:

     A.   Non-Payment.  There  shall occur a failure to pay when due any payment
          of principal or interest or any other sum referred to in this Security
          Agreement  or  under  any  other  document,  instrument  or  agreement
          evidencing or relating to any indebtedness  owed by the Grantor to the
          Bank or owed to the Bank by any obligor on the Indebtedness.

     B.   Performance Under This and Other Agreements. The Grantor shall fail in
          any  material  respect to perform or  observe  any term,  covenant  or
          agreement  contained in this  Security  Agreement or in any  document,
          instrument or agreement  evidencing or relating to any indebtedness of
          the Grantor or any  indebtedness  of any  obligor on the  Indebtedness
          (whether such indebtedness is owed to the Bank or third persons),  and
          any such failure (exclusive of the payment of money to the Bank, which
          failure shall  constitute and be an immediate  Event of Default if not
          paid when due or when demanded to be due) shall continue for more than
          30 days  after  written  notice  from the Bank to the  Grantor  or the
          obligor on the  Indebtedness  of the  existence  and character of such
          Event of Default.

     C.   Representations   and   Warranties;    Financial    Statements.    Any
          representation  or  warranty  made  under or in  connection  with this
          Security Agreement or any financial  statement or information given in
          connection  with the  transaction  with respect to which this Security
          Agreement  is entered  into shall prove to have been  incorrect in any
          material  respect  when made or given or when deemed to have been made
          or given.

     D.   Insolvency.  The  Grantor or any  obligor on or any  guarantor  of the
          Indebtedness shall: (i) become insolvent or be unable to pay its debts
          as they mature;  (ii) make an assignment  for the benefit of creditors
          or to an agent  authorized to liquidate any substantial  amount of its

     E.   Execution.  Any writ of execution or  attachment  or any judgment lien
          shall be issued  against the Collateral and shall not be discharged or
          bonded  against  or  released  within 30 days  after the  issuance  or
          attachment of such writ or lien.

     F.   Impairment  of  Collateral.  There  shall occur any  deterioration  or
          impairment  of all or any part of the  Collateral  or any  decline  or
          depreciation  in the value or  market  price of the  Collateral  which
          causes the Collateral,  in the sole and absolute judgment of the Bank,
          to become unacceptable as to character or value.

     G.   Revocation or Limitation of Guaranty.  Any guaranty given with respect
          to the Indebtedness  shall be revoked or limited or its enforceability
          or validity shall be contested by any guarantor,  by operation of law,
          legal proceeding or otherwise or any guarantor who is a natural person
          shall die.

     H.   Suspension.  The  Grantor  or any  obligor on the  Indebtedness  shall

          necessary to conduct such person's business as now conducted.

     I.   Change in Ownership.  There shall occur a sale, transfer,  disposition
          or encumbrance  (whether  voluntary or  involuntary),  or an agreement
          shall be entered  into to do so, with  respect to more than 10% of the
          issued and outstanding  capital stock of the Grantor or any obligor on
          the Indebtedness,  if a corporation,  or there shall occur a change in
          any general  partner or a change  affecting the control of the Grantor
          or any obligor on the Indebtedness, if a partnership.

7.   Bank's Rights and Remedies on Default.  Upon the  occurrence of  any  Event
     of Default,  the  Bank  may, at its sole  and  absolute  election,  without
     demand and only upon such notice as may be required by law:

     A.   Acceleration.   Declare  the   Indebtedness   and  any  or  all  other
          indebtedness  owing to the Bank by the  Grantor or any  obligor on the
          Indebtedness  (however such  indebtedness may be evidenced or secured)
          immediately due and payable, whether or not otherwise due and payable.

     B.   Cease Extending  Credit.  Cease extending credit to or for the account
          of the Grantor or any obligor on the Indebtedness  under any agreement
          now existing or hereafter entered into with the Bank.

     C.   Termination.  Terminate any  agreement as to any future  obligation of
          the Bank without  affecting the Grantor's  obligations  to the Bank or
          the Bank's rights and remedies under this Security  Agreement or under
          any other document, instrument or agreement.

     D.   Protection of Security Interest in Collateral.  Make such payments and
          do such acts as the Bank, in its sole  judgment,  considers  necessary
          and reasonable to protect its security interest in the Collateral. The
          Grantor  hereby  irrevocably  authorizes  the  Bank to pay,  purchase,
          contest or compromise any  encumbrance,  lien or claim which the Bank,
          in its sole  judgment,  deems to be prior or superior to its  security
          interest.  Further, the Grantor hereby agrees to pay to the Bank, upon
          demand therefor,  all expenses and expenditures  (including attorneys'
          fees) incurred in connection with the foregoing.

     E.   Foreclosure.  Enforce any security  interest or lien given or provided
          for under this Security Agreement or under any other document relating
          to the  Collateral,  in such manner and such  order,  as to all or any
          part of the Collateral, as the Bank, in its sole judgment, deems to be
          necessary or  appropriate  and the Grantor  hereby  waives any and all
          rights,  obligations  or defenses now or hereafter  established by law
          relating to the foregoing. In the enforcement of its security interest
          in the  Collateral,  the Bank is authorized to enter upon the premises
          where any Collateral is located and take  possession of the Collateral
          or any part thereof,  together with the Grantor's  records  pertaining
          thereto,  or  the  Bank  may  require  the  Grantor  to  assemble  the
          Collateral and records pertaining thereto and make such Collateral and
          records  available to the Bank at a place  designated by the Bank. The
          Bank may sell the  Collateral or any portions  thereof,  together with
          all additions,  accessions and accessories  thereto,  giving only such
          notices and following only such  procedures as are required by law, at
          either a public or private sale, or both,  with or without  having the
          Collateral  present  at the time of sale,  which sale shall be on such
          terms  and  conditions  and  conducted  in  such  manner  as the  Bank
          determines in its sole  judgment to be  commercially  reasonable.  Any
          deficiency  which exists after the  disposition  or liquidation of the
          Collateral  shall be a  continuing  liability of any obligor on or any
          guarantor of the  Indebtedness  and shall be  immediately  paid to the
          Bank.

     F.   Application of Proceeds.  All amounts received by the Bank as proceeds
          from the disposition or liquidation of the Collateral shall be applied
          as follows: first, to the costs and expenses of collection,  including
          court costs and  reasonable  attorneys'  fees,  whether or not suit is
          commenced by the Bank;  next, to those costs and expenses  incurred by
          the Bank in protecting,  preserving, enforcing, collecting, selling or
          disposing  of the  Collateral;  next,  to the  payment of accrued  and
          unpaid  interest on all of the  Indebtedness;  next, to the payment of
          the outstanding  principal balance of the  Indebtedness;  and last, to
          the payment of any other indebtedness owed by the Grantor to the Bank.
          Any  excess   Collateral  or  excess   proceeds   existing  after  the
          disposition or liquidation of the Collateral  will be returned or paid
          by the Bank to the Grantor.

     G.   Non-Exclusivity of Remedies. Exercise one or more of the Bank's rights
          set forth  herein  or seek such  other  rights  or pursue  such  other
          remedies  as may  be  provided  by  law,  in  equity  or in any  other
          agreement now existing or hereafter  entered into between the Bank and
          the Grantor or any obligor on or  guarantor  of the  Indebtedness,  or
          otherwise.


8.    Miscellaneous Provisions.

     A.   Amounts Payable Under this Security Agreement. If the Grantor fails to
          pay on  demand  the  amount  of any  obligations  referred  to in this
          Security  Agreement,  the Bank may pay such  amount at its  option and
          without  any  obligation  to do so and  without  waiving  any  default
          occasioned by the Grantor's failure to pay such amount. All amounts so
          paid by the Bank,  together with  reasonable  attorneys'  fees and all
          other costs, charges and expenses relating to the Indebtedness,  shall
          be a part of the  Indebtedness  and shall bear interest at the highest
          rate chargeable on any Indebtedness until paid in full.

     B.   Other Terms.  Terms not otherwise  defined in this Security  Agreement
          shall have the  meanings  attributed  to such terms in the  California
          Uniform Commercial Code.

     C.   Reliance.  Each  warranty,  representation,   covenant  and  agreement
          contained in this Security Agreement shall be conclusively presumed to
          have been relied upon by the Bank regardless of any investigation made
          or  information  possessed by the Bank and shall be cumulative  and in
          addition  to  any  other  warranties,  representations,  covenants  or
          agreements  which the Grantor shall now or hereafter give, or cause to
          be given, to the Bank.

     D.   Attorneys'  Fees.  In the  event of any  action  in  relation  to this
          Security  Agreement,  the  Collateral or any  document,  instrument or
          agreement  secured hereby or related hereto,  the prevailing party, in
          addition  to all  other  sums to  which it may be  entitled,  shall be
          entitled to reasonable attorneys' fees.

     E.   Notices.  All notices,  payments,  requests,  information  and demands
          which either  party hereto may desire,  or be required to give or make
          to the  other  party,  shall be  given  or made to such  party by hand
          delivery  or  through  deposit  in the  United  States  mail,  postage
          prepaid,  or by Western Union  telegram,  addressed to the address set
          forth below such party's  signature to this  Security  Agreement or to
          such other address as may be specified from time to time in writing by
          either party to the other.

     F.   Waiver.  Neither the failure nor delay by the Bank in  exercising  any
          right  hereunder  or  under  any  document,  instrument  or  agreement
          mentioned  herein  shall  operate as a waiver  thereof,  nor shall any
          single or partial  exercise of any right  hereunder or under any other
          document,  instrument or agreement  mentioned herein preclude other or
          further exercise thereof or the exercise of any other right; nor shall
          any  waiver  of any  right or  default  hereunder  or under  any other
          document, instrument or agreement mentioned herein constitute a waiver
          of any other  right or  default  or  constitute  a waiver of any other
          default of the same or any other term or provision.

     G.   Assignment. This Security Agreement shall be binding upon and inure to
          the  benefit  of  the  Grantor  and  the  Bank  and  their  respective
          successors  and  assigns,  except that the Grantor  shall not have the
          right to assign the Grantor's  rights hereunder or any interest herein
          without the Bank's prior written consent.  The Bank may sell or assign
          all or any  portion of its  rights  and  benefits  hereunder  and,  in
          connection  therewith,  may  deliver  to  such  prospective  buyer  or
          assignee   financial   statements  and  other   relevant   information
          pertaining to the Grantor or any obligor on the Indebtedness.

     H.   Severability.  Should  any one or  more  provisions  of this  Security
          Agreement  be  determined  to be illegal or  unenforceable,  all other
          provisions shall remain effective.

     I.   Jurisdiction.  This  Security  Agreement and the rights of the parties
          hereunder  to  and  concerning  the  Collateral,  and  any  documents,
          instruments  or agreements  mentioned or referred to herein,  shall be
          governed  by and  construed  according  to the  laws of the  State  of
          California,  to the  jurisdiction  of whose courts the parties  hereby

                                  Exhibit 10.5


                               CONTINUING GUARANTY

For value received and in consideration of the extension of credit by SANWA BANK
CALIFORNIA  (the "Bank") to MICHAEL D. FARNEY (the  "Debtor") or the benefits to
the undersigned derived therefrom, the undersigned (the "Guarantor"), guarantees
and promises to pay to the Bank any and all  Indebtedness (as defined below) and
agrees as follows:

1.   Indebtedness.   The  term  "Indebtedness"  is  used   herein  in  its  most
     comprehensive sense and  includes any and all advances, debts, obligations,
     guaranties  and  liabilities  of the Debtor  heretofore,  now, or hereafter
     made,incurred  or created,  whether  voluntary or  involuntary  and however
     arising,   whether  direct  or  acquired  by  the  Bank  by  assignment  or
     succession,  whether due or not due, absolute or contingent,  liquidated or
     unliquidated,  determined  or  undetermined,  and whether the Debtor may be
     liable  individually or jointly with others,  or whether  recovery upon any
     Indebtedness  may  be  or  hereafter  becomes  barred  by  any  statute  of
     limitations  or  whether  any  Indebtedness  may  be or  hereafter  becomes
     otherwise unenforceable.

2.   Guaranty.  The Guarantor  unconditionally  agrees to pay to the Bank or its
     order,  on demand,  an amount  equal to the amount of the  Indebtedness  or
     otherwise perform any obligation of the Debtor  undertaken  pursuant to any
     Indebtedness. In addition to any maximum principal liability hereunder, the
     Guarantor  agrees  to (i) bear the  expenses  enumerated  hereunder  in the
     paragraph  herein entitled  "Attorneys'  Fees" and (ii) pay interest on the
     Indebtedness  at  the  rate(s)  applicable  thereto.   Notwithstanding  the
     foregoing,  the Bank may allow the  Indebtedness  to exceed the Guarantor's
     liability  hereunder.  Any  payment by the  Guarantor  shall not reduce the
     maximum  principal  obligation of the Guarantor  hereunder  unless  written
     notice to that effect is  actually  received by the Bank at or prior to the
     time of such  payment.  Any payment by the Debtor or any other person shall
     not reduce the Guarantor's maximum principal liability hereunder.

3.   Right to Amend or Modify  Indebtedness.  The Guarantor authorizes the Bank,
     at its sole discretion,  with or without notice and  without affecting  the
     Guarantor's  liability hereunder,  from time  to  time  to: (i) change  the
     time or  manner of  payment  of any  Indebtedness  by  renewal,  extension,
     modification, acceleration or otherwise; (ii) alter or change any provision
     of any  Indebtedness  including,  but not  limited to, the rate of interest
     thereon,  and any  document,  instrument  or  agreement  (other  than  this
     Guaranty)   evidencing,   guaranteeing,   securing   or   related   to  any
     Indebtedness; (iii) release, discharge, exonerate, substitute or add one or
     more parties liable on any Indebtedness or one or more endorsers, cosigners
     or guarantors for any Indebtedness;  (iv) obtain collateral for the payment
     of any  Indebtedness  or any  guaranty  thereof;  (v)  release  existing or
     after-acquired   collateral  on  such  terms  as  the  Bank,  in  its  sole
     discretion,  shall determine; (vi) apply any sums received from the Debtor,
     any  endorser,  cosigner,  other  guarantor or other  person  liable on any
     Indebtedness  or from the sale or  collection of collateral or its proceeds
     to any indebtedness whatsoever owed or to be owed to the Bank by the Debtor
     in any order or amount and  regardless of whether or not such  indebtedness
     is guaranteed  hereby, is secured by collateral or is due and payable;  and
     (vii)  apply to any  Indebtedness,  in any order or amount,  regardless  of
     whether such  Indebtedness  is secured by collateral or is due and payable,
     any sums  received  from the  Guarantor or from the sale of  collateral  in
     which the Guarantor has granted the Bank a security interest.

4.   Waivers.  The Guarantor hereby unconditionally and irrevocably acknowledges
     and agrees to the matters set forth below.

       A. Deficiency.  In the event that any  Indebtedness is  now  or hereafter
          secured by a deed of trust,  the Guarantor  waives any defense and all
          rights  and  benefits  of  those  laws  purporting  to  state  that no
          deficiency judgment may be recovered on certain real property purchase
          money  obligations  (as  presently  contained  in Section  580b of the
          California  Code  of  Civil  Procedure  and as it may  be  amended  or
          superseded  in the future) and those laws  purporting to state that no
          deficiency  judgment may be recovered  after a trustee's  sale under a
          deed  of  trust  (as  presently  contained  in  Section  580d  of  the
          California  Code  of  Civil  Procedure  and as it may  be  amended  or
          superseded  in  the  future).   THE  GUARANTOR   ACKNOWLEDGES  THAT  A
          FORECLOSURE  BY A  TRUSTEE'S  SALE UNDER A DEED OF TRUST MAY RESULT IN
          THE  DESTRUCTION  OF  THE  GUARANTOR'S  SUBROGATION  RIGHTS  THAT  MAY
          OTHERWISE  EXIST AND THAT A  DESTRUCTION  OF THOSE RIGHTS MAY CREATE A
          DEFENSE TO A DEFICIENCY  JUDGEMENT.  THE GUARANTOR HEREBY SPECIFICALLY
          WAIVES ANY SUCH DEFENSE.

       B. Election of Remedies.  The Guarantor waives any defense based upon the
          Guarantor's loss of a right against the Debtor arising from the Bank's
          election of a remedy on any  Indebtedness  under  bankruptcy  or other
          debtor relief laws or under any other laws, including, but not limited
          to, those  purporting to reduce the Bank's right against the Guarantor
          in  proportion to the principal  obligation  of any  Indebtedness  (as
          presently  contained in Section 2809 of the California  Civil Code and
          as it may be amended or superseded in the future).

          Without limiting the generality of the foregoing, the Guarantor waives
          all rights and defenses  arising out of an election of remedies by the
          Bank,  even though that  election of remedies,  such as a  nonjudicial
          foreclosure with respect to security for a guaranteed obligation,  has
          destroyed the  Guarantor's  rights of  subrogation  and  reimbursement
          against the Debtor by operation of Section 580d of the California Code
          of Civil Procedure or otherwise.

       C. Statute  of  Limitations.  The  Guarantor  waives  the  benefit of the
          statute of limitations  affecting  Guarantor's  liability hereunder or
          the enforcement hereof.

       D. Action Against the Debtor and  Collateral  (and Other  Remedies).  The
          Guarantor waives all right to require the Bank to: (i) proceed against
          the Debtor,  any endorser,  cosigner,  other guarantor or other person
          liable  on any  Indebtedness;  (ii) join the  Debtor or any  endorser,
          cosigner,  other guarantor or other person liable on any  Indebtedness
          in any action or actions  that may be brought  and  prosecuted  by the
          Bank solely and separately  against the Guarantor on any Indebtedness;
          (iii)  proceed  against any item or items of  collateral  securing any
          Indebtedness or any guaranty  thereof;  or (iv) pursue or refrain from
          pursuing any other remedy whatsoever in the Bank's power.

       E. Debtor's Defenses.  The Guarantor waives any defense arising by reason
          of any  disability  or  other  defense  of the  Debtor,  the  Debtor's
          successor or any endorser,  cosigner,  other guarantor or other person
          liable on any  Indebtedness.  Until all  Indebtedness has been paid in
          full,  even  though  it may be in  excess  of the  liability  incurred
          hereby,  the Guarantor shall not have any right of subrogation and the
          Guarantor  waives  any  benefit  of and  right to  participate  in any
          collateral now or hereafter held by the Bank. The Guarantor waives all
          presentments,  demands  for  performance,  notices of  nonperformance,
          protests,  notices of protest, notices of dishonor, notices of sale of
          any collateral securing any Indebtedness or any guaranty thereof,  and
          notice of the  existence,  creation or incurring of new or  additional
          Indebtedness.

       F. Debtor's  Financial   Condition.   The  Guarantor  hereby  recognizes,
          acknowledges  and agrees that  advances may be made in the future from
          time to time with respect to any  Indebtedness  without  authorization
          from or notice to the Guarantor even though the financial condition of
          the Debtor,  any endorser,  cosigner,  other guarantor or other person
          liable on any  Indebtedness  may have  deteriorated  since the date of
          this Guaranty.  The Guarantor  waives all right to require the Bank to
          disclose any  information  with respect to: (i) any  Indebtedness  now
          existing or hereafter  incurred;  (ii) the present or future financial
          condition, credit or character of the Debtor, any endorser,  cosigner,
          other guarantor or other person liable on any Indebtedness;  (iii) any
          present or future collateral securing any Indebtedness or any guaranty
          thereof;  or (iv) any present or future action or inaction on the part
          of the Bank, the Debtor or any endorser,  cosigner, other guarantor or
          other person liable on any Indebtedness.  The Guarantor hereby assumes
          the  responsibility  for being  informed of the  financial  condition,
          credit and  character of the Debtor and of all  circumstances  bearing
          upon  the  risk of  non-payment  of any  Indebtedness  which  diligent
          inquiry would reveal.

5.    Right of  Set-off;  Grant of Security  Interest.  In addition to all liens
      upon and  rights  of  set-off  against  any  monies,  securities  or other
      property of the Guarantor  given to the Bank by law, the Bank shall have a
      security interest in and a right to set off against all monies, securities
      and other  property of the Guarantor now or hereafter in the possession of
      or on deposit with the Bank, the Bank's agents or any one or more of them,
      whether held in general or special  account or deposit or for  safekeeping
      or otherwise;  and each such security interest and right of set-off may be
      exercised  without  demand upon or notice to the  Guarantor.  No action or
      inaction  by the Bank with  respect to any  security  interest or right of
      set-off  shall be deemed a waiver  thereof  and every right of set-off and
      security   interest   shall  continue  in  full  force  and  effect  until
      specifically  released  by the  Bank in  writing.  The  security  interest
      created hereby shall secure all of the Guarantor's  obligations under this
      Guaranty.

6.    Right  of  Foreclosure.   The  Bank  may  foreclose,  either  by  judicial
      foreclosure  or by exercise of power of sale,  any deed of trust  securing
      any Indebtedness  even though such foreclosure may destroy or diminish the
      Guarantor's  rights against the Debtor.  The Guarantor  shall be liable to
      the Bank for any part of any Indebtedness  remaining unpaid after any such
      foreclosure whether or not such foreclosure was for fair market value.

7.    Subordination.  Any indebtedness of the Debtor or any endorser,  cosigner,
      other  guarantor  or  other  person  liable  on  any  Indebtedness  now or
      hereafter   owed  to  the   Guarantor  is  hereby   subordinated   to  the
      Indebtedness.  Such  indebtedness owed to the Guarantor shall, if the Bank
      so requests,  be  collected,  enforced  and  received by the  Guarantor as
      trustee  for the  Bank  and be paid  over to the  Bank on  account  of the
      Indebtedness but without reducing or affecting in any manner the liability
      of the Guarantor set forth  herein.  Should the Guarantor  fail to collect
      the proceeds of any such  indebtedness  owed to it and pay the proceeds to
      the Bank, the Bank, as the Guarantor's attorney-in-fact,  may do such acts
      and sign such  documents  in the  Guarantor's  name as the Bank  considers
      necessary to effect such collection.

8.   Invalid, Fraudulent or Preferential Payments. The Guarantor agrees that, to
     the extent the Debtor or any endorser,  cosigner,  other guarantor or other
     person  liable on any  Indebtedness  makes a payment or payments  to, or is
     credited for any payment or payments made for or on behalf of the Debtor to
     the Bank, which payment or payments,  or any part thereof,  is subsequently
     invalidated,  determined  to be fraudulent  or  preferential,  set aside or
     required to be repaid to any trustee, receiver, assignee or any other party
     whether under any bankruptcy,  state or federal law or under any common law
     or  equitable  cause  or  otherwise,  then,  to  the  extent  thereof,  the
     obligation  or part  thereof  intended  to be  satisfied  thereby  shall be
     revived,  reinstated  and  continued  in full  force and  effect as if such
     payment or payments had not originally been made or credited.

9.    Joint and Several Obligations;  Independent Obligations.  If more than one
      Guarantor  signs this Guaranty,  the  obligations  hereunder are joint and
      several.  The  Guarantor's  obligations  hereunder are  independent of the
      obligations of the Debtor or any endorser,  cosigner,  other  guarantor or
      other person liable on any  Indebtedness  and a separate action or actions
      may be brought and prosecuted against the Guarantor on any Indebtedness.

10.   Acknowledgement  of  Receipt.  Receipt of a true copy of this  Guaranty is
      hereby acknowledged by the Guarantor. The Guarantor understands and agrees
      that this  Guaranty  shall  not  constitute  a  commitment  of any  nature
      whatsoever by the Bank to renew or hereafter  extend credit to the Debtor.
      The Guarantor agrees that this Guaranty shall be effective with or without
      notice from the Bank of the Bank's acceptance hereof.

11.   Continuing Guaranty.  This Guaranty is a continuing  guaranty.  Revocation
      shall be effective  only upon  written  notice  personally  received by an
      officer of the Bank at the originating  office indicated below or actually
      received at the originating  office by United States mail postage prepaid.
      Notice shall be effective at any office of the Bank should the originating
      office no longer be in  existence.  Revocation  shall be  effective at the
      close of the Bank's  business  day when such notice is actually  received.
      Any revocation  shall be effective only as to the revoking party and shall
      not affect  that  party's  obligation  with  respect  to any  Indebtedness
      existing before such revocation is effective.

12.   Non-Reliance.  In executing this Guaranty, the undersigned is not relying,
      and has not relied, upon any statement or representation made by the Bank,
      or any employee,  agent or representative of the Bank, with respect to the
      status,  financial condition or other matters related to the Debtor or the
      relationship between the Debtor and the Bank.


13.   Multiple  Guaranties.  If the  Guarantor has executed or does execute more
      than one  guaranty  of any  indebtedness  of the  Debtor to the Bank,  the
      limits of liability thereunder and hereunder shall be cumulative.

14.   Severability.  Should  any one or more  provisions  of  this  Guaranty  be
      determined  to be illegal or  unenforceable,  all other  provisions  shall
      remain effective.

15.   Corporate or  Partnership  Authority.  If the Debtor is a  corporation  or
      partnership, the Bank need not inquire into the power of the Debtor or the
      authority  of its  officers,  directors,  partners  or  agents  acting  or
      purporting  to act in its behalf and any credit  granted in reliance  upon
      the purported exercise of such power or authority is guarantied hereunder.

16.   Separate  Property.  Any married person who signs this Guaranty  expressly
      agrees that  recourse may be had against such person's  separate  property
      for all obligations hereunder.

17.   Collateral. This  Continuing  Guaranty is secured by a Security  Agreement
      dated as of February  17, 1998  executed by the Guarantor on behalf of the
      Debtor.

18.   Assignment.  The Bank may, with or without notice, assign this Guaranty in
      whole or in part.  This  Guaranty  shall inure to the benefit of the Bank,
      its  successors  and  assigns,  and  shall  bind  the  Guarantor  and  the
      Guarantor's heirs, executors, administrators, successors and assigns.

19.   Waiver  of  Jury.  The  Guarantor  and  the  Bank  hereby   expressly  and
      voluntarily waive any and all rights, whether arising under the California
      constitution,  any rules of the California Code of Civil Procedure, common
      law or otherwise,  to demand a trial by jury in any action,  matter, claim
      or cause of action whatsoever arising out of or in any way related to this
      Guaranty  or any other  agreement,  document or  transaction  contemplated
      hereby.

20.   Dispute Resolution.

       A. Disputes.  It is understood  and agreed that,  upon the request of any
          party to this Guaranty, any dispute, claim or controversy of any kind,
          whether in contract  or in tort,  statutory  or common  law,  legal or
          equitable,  now existing or hereinafter arising between the parties in
          any way arising out of,  pertaining to or in connection with: (i) this
          Guaranty,  or any related agreements,  documents or instruments,  (ii)
          all  past and  present  loans,  credits,  accounts,  deposit  accounts
          (whether  demand  deposits  or time  deposits),  safe  deposit  boxes,
          safekeeping  agreements,  guarantees,  letters  of  credit,  goods  or
          services, or other transactions,  contracts or agreements of any kind,
          (iii)  any  incidents,  omissions,  acts,  practices,  or  occurrences
          causing  injury  to any party  whereby  another  party or its  agents,
          employees or  representatives  may be liable,  in whole or in part, or
          (iv) any aspect of the past or present  relationships  of the parties,
          shall be  resolved  through  a  two-step  dispute  resolution  process
          administered by the Judicial  Arbitration & Mediation  Services,  Inc.
          ("JAMS") as follows:

       B. Step I - Mediation.  At the request of any party to the dispute, claim
          or controversy,  the matter shall be referred to the nearest office of
          JAMS for mediation,  which is an informal,  non-binding  conference or
          conferences  between the  parties in which a retired  judge or justice
          from the JAMS panel will seek to guide the parties to a resolution  of
          the case.

       C. Step II - Arbitration (Contracts Not Secured By Real Property). Should
          any dispute,  claim or controversy remain unresolved at the conclusion
          of the Step I Mediation Phase, then (subject to the restriction at the
          end of this subparagraph) all such remaining matters shall be resolved
          by final and binding arbitration before a different judicial panelist,
          unless the parties  shall agree to have the  mediator  panelist act as
          arbitrator. The hearing shall be conducted at a location determined by
          the  arbitrator in Los Angeles,  California (or such other city as may
          be agreed upon by the  parties)  and shall be  administered  by and in
          accordance  with the then existing  Rules of Practice and Procedure of
          JAMS and judgement  upon any award  rendered by the  arbitrator may be
          entered by any State or Federal Court having jurisdiction thereof. The
          arbitrator  shall  determine  which is the prevailing  party and shall
          include  in the award  that  party's  reasonable  attorneys'  fees and
          costs.  This  subparagraph  shall  apply  only if,  at the time of the
          submission  of the matter to JAMS,  the dispute or issues  involved do
          not arise out of any  transaction  which is secured  by real  property
          collateral or, if so secured, all parties consent to such submission.

          As  soon  as  practicable  after  selection  of  the  arbitrator,  the
          arbitrator,  or  the  arbitrator's  designated  representative,  shall
          determine a reasonable  estimate of anticipated  fees and costs of the
          arbitrator,  and render a statement to each party  setting  forth that
          party's pro-rata share of said fees and costs. Thereafter,  each party
          shall,  within 10 days of receipt of said statement,  deposit said sum
          with the arbitrator. Failure of any party to make such a deposit shall
          result in a  forfeiture  by the  non-depositing  party of the right to
          prosecute or defend the claim which is the subject of the arbitration,
          but  shall  not  otherwise  serve  to  abate,   stay  or  suspend  the
          arbitration  proceedings. 

       D. Step  II  -  Trial  By  Court  Reference(Contracts   Secured  By  Real
          Property). If the dispute, claim or controversy is not one required or
          agreed  to be  submitted  to  arbitration,  as  provided  in the above
          subparagraph,  and has not been resolved by Step I mediation, then any
          remaining  dispute,  claim  or  controversy  shall  be  submitted  for
          determination by a trial on Order of Reference  conducted by a retired
          judge or  justice  from the panel of JAMS  appointed  pursuant  to the
          provisions  of  Section  638(1)  of  the  California   Code  of  Civil
          Procedure, or any amendment, addition or successor section thereto, to
          hear the case and report a statement of decision thereon.  The parties
          intend this general reference agreement to be specifically enforceable
          in accordance  with said  section.  If the parties are unable to agree
          upon a member of the JAMS panel to act as  referee,  then one shall be
          appointed by the Presiding  Judge of the county wherein the hearing is
          to be held.  The parties  shall pay in advance,  to the  referee,  the
          estimated  reasonable  fees  and  costs  of the  reference,  as may be
          specified in advance by the referee. The parties shall initially share
          equally,  by paying their  proportionate  amount of the estimated fees
          and costs of the  reference.  Failure  of any party to make such a fee
          deposit  shall result in a forfeiture by the  non-depositing  party of
          the  right to  prosecute  or defend  any cause of action  which is the
          subject of the reference, but shall not otherwise serve to abate, stay
          or suspend the reference proceeding.

       E. Provisional  Remedies,  Self Help and Foreclosure.  No  provision  of,
          or the  exercise  of any  rights  under any  portion  of this  Dispute
          Resolution  provision,  shall limit the right of any party to exercise
          self help  remedies such as set off,  foreclosure  against any real or
          personal  property  collateral,  or the  obtaining of  provisional  or
          ancillary remedies,  such as injunctive relief or the appointment of a
          receiver,  from any court having jurisdiction before,  during or after
          the pendency of any  arbitration.  At the Bank's  option,  foreclosure
          under a deed of  trust  or  mortgage  may be  accomplished  either  by
          exercise of power of sale under the deed of trust or  mortgage,  or by
          judicial foreclosure. The institution and maintenance of an action for
          provisional remedies,  pursuit of provisional or ancillary remedies or
          exercise of self help  remedies  shall not  constitute a waiver of the
          right of any party to submit the controversy or claim to arbitration.

21.   Attorneys'  Fees.  Whether or not any suit,  action,  arbitration or other
      dispute resolution  proceeding is instituted,  the Guarantor agrees to pay
      reasonable  attorneys'  fees and all other costs and expenses which may be
      incurred in the  collection  of any  Indebtedness,  in the  protection  or
      preservation   of,  or  realization   on,  any  collateral   securing  any
      Indebtedness and in the enforcement by the Bank of this Guaranty.

22.   Governing Law. This Guaranty shall be governed by and construed  according
      to the laws of the State of California and the Guarantor hereby submits to
      the jurisdiction of the courts of the State of California.

23.   Entire  Agreement.  This  Guaranty  and  all  documents,  instruments  and
      agreements   mentioned   herein   constitute   the  entire  and   complete
      understanding of the parties with respect to the transactions contemplated
      hereunder. All previous conversations,  memoranda and writings between the
      parties  pertaining  to  the  transactions   contemplated   hereunder  not
      incorporated  or  referenced  in  this  Guaranty  or  in  such  documents,
      instruments and agreements are superseded hereby.

24.   Headings.   The  headings  used  herein  are solely  for  the  purpose  of
      identification and have no legal significance.

25.   Address of the Bank.  The Bank's  originating  office  under this Guaranty
      is: Santa Barbara Main Office, 1036 State Street, Santa Barbara, CA 93101.

26.   Maximum Principal  Liability.  THE MAXIMUM PRINCIPAL  LIABILITY UNDER THIS
      GUARANTY  IS the amount of  $7,600,000.00,  plus  interest  at the rate(s)

                         ADDENDUM TO CONTINUING GUARANTY


                  THIS ADDENDUM TO CONTINUING  GUARANTY (the "Addendum") is made
and dated as of the 17th day of February,  1998, by and between MIRAVANT MEDICAL
TECHNOLOGIES ("Guarantor"), and SANWA BANK CALIFORNIA ("Bank").

                                    RECITALS

                  A.  Pursuant  to  that  certain  Term  Loan  Agreement   dated
concurrently  herewith,  Bank agreed to extend  credit to MICHAEL D. FARNEY,  an
individual  (the "Debtor") in the form of a  $7,600,000.00  term loan (the "Term
Loan") on the terms and subject to the  conditions  set forth more  particularly
therein  (as  amended,  extended  and  replaced  from  time to time,  the  "Loan
Agreement," and with  capitalized  terms not otherwise  defined herein used with
the meanings  given such terms in the Loan  Agreement).  The  obligations of the
Debtor with  respect to the Term Loan,  including,  without  limitation,  to pay
principal  and interest on amounts  outstanding  under the Loan  Agreement,  are
secured by certain collateral  consisting generally of outstanding capital stock
of Guarantor owned by the Debtor (the "Pledged  Stock") pursuant to the terms of
the Loan Agreement.

                  B. As a condition  precedent to the  agreement of Bank to fund
the Term Loan to the Debtor,  Bank has required Guarantor to execute and deliver
a credit guaranty of the obligations of the Debtor with respect to the Term Loan
in the form of the Continuing Guaranty dated concurrently herewith to which this
Addendum is attached (as amended,  extended and replaced from time to time,  the
"Guaranty").

                  C. In addition to providing  the  Guaranty,  Bank has required
that  Guarantor  agree under  certain  circumstances  to purchase from Bank upon
demand  the  Term  Loan and all  right,  title  and  interest  of Bank  therein,
including, without limitation, under the Loan Agreement, (the "Loan Package").

                  D.  Guarantor  and Bank desire to set forth in this  Addendum,
which is  attached  to and  hereby  made a part of the  Guaranty,  the terms and
conditions under which Bank may require Guarantor to purchase the Loan Package.

                  NOW, THEREFORE, in consideration of the above Recitals and for
other good and  valuable  consideration  the receipt  and  adequacy of which are
hereby acknowledged, the parties hereto hereby agree as follows:

                                    AGREEMENT

                  1. Purchase Commitment.  Guarantor hereby agrees that upon the
delivery to Guarantor  of written  notice from Bank that a Put Event (as defined
below) has occurred,  Guarantor  absolutely and  unconditionally  agrees that no
later than one (1) Business Day thereafter Guarantor will purchase and take from
Bank all of Bank's right,  title and interest in the Loan Package.  For purposes
of this  Paragraph l, the term "Put Event" shall mean:  (a) the occurrence of an
Event  of  Default  under  the Loan  Agreement,  or (b)  receipt  by Bank of any
instruction  from,  or request by or on behalf of, the Debtor which Bank, in its
reasonable business judgment,  concludes constitutes a request or demand to sell
or  otherwise  dispose  of the  Pledged  Stock due to a decline  or  anticipated
decline in the value thereof .

                  2.  Purchase  Price.  The  purchase  price  to be  paid by the
Guarantor for Bank's  right,  title and interest in the Loan Package shall be an
amount equal to the sum of: (a) the outstanding principal balance under the Loan
Agreement, (b) interest accrued and unpaid thereon to and including the purchase
date, plus (c) all other  Obligations  outstanding.  The purchase price shall be
paid to Bank in lawful money of the United States and in  immediately  available
funds on the purchase date.

                  3. Delivery of Loan Package;  Transfer Expenses.  Upon payment
in full by the Purchaser to Bank of the purchase  price  pursuant to Paragraph 2
above,  Bank shall deliver to Guarantor an  assignment  of the right,  title and
interest of Bank in the Loan Agreement and such other documents, instruments and
agreements  relating to the Term Loan as Guarantor may reasonably  request which
are in  Guarantor's  judgment  necessary to transfer  Bank's  rights in the Loan
Package to it; provided,  however, that Guarantor  acknowledges that the Special
Power of  Attorney  granted  by  Borrower  to Bank is  personal  to Bank and not
transferrable.  Any and  all  endorsements,  assignments  and  other  documents,
instruments and agreements  executed by Bank hereunder shall be without recourse
to  and,   except  as  expressly  set  forth  in  Paragraph  4  below,   without
representation  or warranty,  express or implied,  by Bank.  Guarantor  shall be
responsible  for all costs and  expenses  incurred or assessed  against  Bank in
connection with such transfer all of which shall be payable by Guarantor to Bank
upon demand with interest  thereon at the Reference  Rate minus 1.000% per annum
(computed  on the basis of a 360-day  year) from the date demand is made by Bank
until paid in full.

                  4. Representation and Warranty. On and as of the purchase date
for the Loan Package sold and  transferred as contemplated  hereby,  Bank hereby
represents  and  warrants  that  immediately  prior to the  consummation  of the
purchase and sale  transaction  Bank had good title to and was the sole owner of
the Loan Package and upon payment by  Guarantor of the purchase  price  therefor
Guarantor  will have good title to the Loan  Package free and clear of any lien,
claim or other interest of any person or entity claiming by or through Bank.

                  5. Extent of Obligations.  Guarantors'  obligation to purchase
the right,  title and interest of Bank in the Loan Package as provided herein is
absolute  and  unconditional  and  subject to all  waivers  and other  terms and
provisions set forth in the Guaranty, including, without limitation, Paragraph 4
thereof.  Without  limiting the  generality of the foregoing,  Guarantor  hereby
independently  and irrevocably  waives:  (a) any defense to such obligation that
may arise by reason of the disability or other defense or cessation of liability
of the Debtor  for any reason  other than full  payment;  (b)  deferral  of such
obligation  arising  by reason of the  institution  of  bankruptcy,  insolvency,
reorganization, moratorium or other similar proceedings by or against the Debtor
or any other  person or entity;  (c) any  defense  arising as a result of Bank's
failure to preserve or protect the Loan Package, including,  without limitation,
the Pledged  Stock or to perfect or maintain the  perfection  or priority of any
lien  thereon or Bank's  exercise  or failure to  exercise  any right,  power or
remedy, including,  without limitation, the failure to proceed first against the
Debtor,  any  security it holds  under the Loan  Agreement,  including,  without
limitation, the Pledged Stock, even when such election or failure impairs alters
or negates the rights of Guarantor against the Debtor, whether arising by way of
subrogation  or otherwise.  Guarantor  agree that Bank may,  without  notice and
without releasing the Guarantor from its obligations under the Guaranty or under
this Addendum,  extend the time for making any payment or extend the performance
of any agreement and may proceed against Guarantor directly and independently of
the Debtor or any other person or entity.

                  6. No Reliance.  Guarantor  confirms  that it has reviewed and
approved the Loan  Agreement and each of the other  documents,  instruments  and
agreements included in the Loan Package.  Guarantor expressly  acknowledges that
neither  Bank  nor  any  of  its   officers,   directors,   employees,   agents,
attorneys-in-fact  or  affiliates  (the  "Bank-Related  Parties")  has  made any
representations  or  warranties  to it with  respect  to the  Debtor or the Loan
Package and that no act by Bank or any  Bank-Related  Party  hereinafter  taken,
including  any review of the affairs of the Debtor shall be deemed to constitute
any  representation  or warranty by Bank or any Bank-Related  Party with respect
thereto.  Guarantor  represents  and  warrants to Bank that in agreeing to enter
into the Guaranty and this Addendum, it has,  independently and without reliance
upon Bank or any Bank-Related Party, and based on such documents and information
as it has deemed  appropriate,  made its own appraisal of and investigation into
the  business,   operations,   property,   financial  and  other  condition  and
creditworthiness  of the  Debtor  and made its own  decision  to enter  into the
Guaranty  and  this   Addendum.   Guarantor  also   represents   that  it  will,
independently  and without  reliance upon Bank or any  Bank-Related  Party,  and
based on such  documents and  information  as it shall deem  appropriate  at the
time,  continue to make its own credit  analysis,  appraisals  and  decisions in
taking or not taking action under the Guaranty  and/or this Addendum and to make
such  investigation  as it deems  necessary to inform itself as to the business,
operations,  property, financial and other condition and creditworthiness of the
Debtor.  Bank shall have no any duty or responsibility to provide Guarantor with
any credit or other information concerning the business,  operations,  property,
financial and other condition or  creditworthiness  of the Debtor which may come
into the possession of Bank or any Bank-Related Party.

                  7.  Relationship  to Guaranty.  All  obligations  of Guarantor
under  this  Addendum  are in  addition  to  and  not in  substitution  for  all
obligations  of Guarantor  under the Guaranty.  Subject to the  foregoing,  this
Addendum is hereby  incorporated  into and shall form a pat of the  Guaranty for
all purposes thereof.

     IN WITNESS  WHEREOF,  the  undersigned  hereby  execute  and  deliver  this
Addendum on and as of the day first above written.

                                  Exhibit 10.7



                            INDEMNIFICATION AGREEMENT


         THIS  INDEMNIFICATION  AGREEMENT (the  "Agreement") is made and entered
into  on the  date  hereinafter  set  forth  by  and  between  MIRAVANT  MEDICAL
TECHNOLOGIES, a Delaware corporation ("MRVT") and MICHAEL D. FARNEY ("Farney").

WHEREAS:

         A. Farney is a Director and  Shareholder  of MRVT and owns Four Hundred
and Thirty Five Thousand  (435,000) shares of MRVT stock,  together with options
to acquire Forty Five Thousand (45,000) shares of MRVT stock (collectively,  the
"Farney Shares");

         B. Farney has pledged  the Farney  Shares to Coutts Bank as  collateral
for a SEVEN MILLION FIVE HUNDRED SIXTY EIGHT  THOUSAND FOUR HUNDRED AND EIGHTEEN
DOLLAR  ($7,568,418)  loan, with interest accruing after February 2, 1998 at TWO
THOUSAND ONE HUNDRED  FOURTEEN  DOLLARS ($2,114) per day (the "Coutts Loan") and
Coutts  Bank  demands  payment and  requests  that MRVT  release any  applicable
legends on stock certificates representing the Farney Shares;

         C. MRVT feels that it is in MRVT's best  interest  to assist  Farney to
resolve the Coutts Bank demand;

         D.  Farney  wishes to secure  the  assistance  of MRVT with  respect to
guaranteeing a loan by Sanwa Bank,  MRVT's principal  banker,  to pay the Coutts
Loan in full; and

         E. MRVT has secured the  approval of a majority of its  Directors  with
respect to this  transaction,  and Farney has abstained from voting with respect
to this matter.

         NOW,  THEREFORE,   in  consideration  of  the  premises  and  promises,
warranties and representations herein contained, it is agreed as follows:

         1. Corporate Guaranty.  MRVT will provide a corporate guaranty to Sanwa
Bank (the "Guaranty") of a loan, for not more than eighteen (18) months,  not to
exceed SEVEN MILLION SIX HUNDRED  THOUSAND DOLLARS  ($7,600,000),  plus interest
payable  quarterly from the date of the loan (the "Sanwa  Loan"),  which will be
used to pay the Coutts  Loan.  The  Guaranty  will be  provided to Sanwa Bank by
MRVT.

         2. Credit Enhancement Fee. Farney will pay to MRVT, at the execution of
the Guaranty and this Agreement,  a credit  enhancement fee equal to two percent
(2%) of the borrowed  amount,  not to exceed SEVEN MILLION SIX HUNDRED  THOUSAND
DOLLARS  ($7,600,000),  payable in MRVT stock (the "Fee  Shares") at the closing
price on the date of this Agreement.

         3.  Pledge of Assets.  Farney  represents  that he will pledge to Sanwa
Bank all the Farney Shares, less the Fee Shares, as well as any other collateral
required by Sanwa Bank, to secure the payment of the Sanwa Loan.

         4. Personal Financial  Statement.  Farney has delivered to the Chairman
of the Board of MRVT, on a confidential  basis, his personal financial statement
as delivered to Sanwa Bank, and Farney  warrants and represents  that it is true
and correct.

         5. Director Status.  Farney has noticed MRVT that he will not stand for
re-election as a Director of MRVT at the 1998 MRVT Annual Shareholders meeting.

         6. Indemnification.  Farney does hereby unconditionally and irrevocably
indemnify  and  hold  harmless  MRVT  from  and  against  any  and  all  losses,
liabilities, claims, demands, and causes of action of any kind or nature related
to this Agreement,  the Sanwa Loan, the Guaranty or the Coutts Loan. Included in
this indemnification is the payment of reasonable legal fees in the event of any
litigation  involving  the  Sanwa  Loan or  Farney's  MRVT  stock as it  relates
directly to a uncured default by Farney of the Sanwa Loan.

         7.  Lock-Up  Agreement.  Farney  agrees  not to sell any of the  Farney
Shares until January 1, 1999 and,  thereafter,  not to sell the Farney Shares in
an  amount  not to exceed up to five  percent  (5%) of the ten (10) day  average
trading volume (as reported by Bloomberg, L.P.) on the date prior to the date of
disposition.  Nothing in this Section 7 is intended to limit Farney's ability to
repay the Sanwa Loan by selling the Farney Shares in off-market  transactions in
an  orderly  manner  to repay  the Sanwa  Loan or  refinancing  with one or more
sources,  so long as the purchaser or refinancier agrees to the foregoing terms;
provided,  however, that MRVT, in its sole and absolute discretion, may agree to
other  arrangements on a mutually  agreeable basis, but this provision shall not
be construed to require MRVT to make any such other  arrangements  if it chooses
not to do so.

         8.  Default.  In the event of (i) a default by Farney in the payment of
the Sanwa Loan, which is not cured by Farney within the cure period of the Sanwa
Loan  agreements,  and result in Sanwa's  demand of full  repayment of the Sanwa
Loan (the "Loan Default Date"),  (ii) a default by Farney in any of the terms of
this Agreement (the "Agreement Default Date"), or (iii) if Sanwa Bank calls upon
MRVT to honor its Guaranty of the Sanwa Loan or puts the Sanwa Loan to MRVT (the
"Guaranty  Performance  Date"),  MRVT may then elect to purchase  the Sanwa Loan
from the Sanwa Bank for the amount due to it and have all of Sanwa Bank's rights
under the Sanwa Loan  agreements,  and Farney will not assert  against  MRVT any
claims he may have against Sanwa Bank. Provided that MRVT elects to purchase the
Sanwa Loan at its unpaid balance,  Farney hereby irrevocably and unconditionally
grants MRVT an  assignable  option  ("Option") to acquire the Farney Shares at a
price equal to fifty  percent (50%) of the 20-day  average  closing price of the
MRVT stock on the exercise date of the Option, net of the Sanwa Loan repayment .
The Option may be exercised  by MRVT or its  assignee  within sixty (60) days of
the  applicable  Loan  Default  Date,  Agreement  Default  Date or the  Guaranty
Performance  Date.  If MRVT does not  exercise  the  Option,  it may  pursue all
remedies available to Sanwa Bank.

         9.  Severability.  Nothing in this  Agreement is intended to require or
shall be construed as requiring  Farney to do or fail to do any act in violation
of  applicable  law. In the event any  provision  of this  Agreement  is finally
determined by the courts to require Farney to do or fail to do such an act, such
provision  shall be limited or modified in its application to the minimum extent
necessary  to avoid a  violation  of law,  and as so  limited or  modified  such
provision and the balance of this  Agreement  shall be enforceable in accordance
with their terms.

         10. Choice of Law; Arbitration. This Agreement is made and entered into
in Santa  Barbara,  California,  and  California  law shall  apply.  Any dispute
between the parties shall be resolved by arbitration,  before one arbitrator, in
Santa  Barbara,  California,  in  accordance  with  the  Rules  of the  American
Arbitration Association.

         11.  Successors  and  Assigns.  This  Agreement  shall be binding  upon
Farney,  and his successors and assigns,  and shall inure to the benefit of MRVT
and MRVT's officers, directors, shareholders, agents and representatives.

         12. Confidentiality. Farney and MRVT will keep all of the terms of this
Agreement  confidential  and will not  disclose  any of those terms  without the
prior written consent of the other party,  except for any obligations of MRVT or
Farney to make a disclosure  as required  under  applicable  federal  securities
laws.

         13. Release.  In  consideration  of this Agreement,  Farney does hereby
irrevocably  and  unconditionally  release  Miravant,  its officers,  directors,
employees,  agents and insureds (collectively,  the "Released Parties") from any
and all  liabilities,  losses,  claims and damages  related to the Sanwa Loan or
this Agreement,  including  MRVT's Option set forth in Section 8 hereof.  Farney
represents  that he has not made an  assignment  of his  claims  and he is fully
authorized to execute this  Agreement.  Farney waives the rights of Section 1542
of the California Civil Code, which provides:

"A general release does not extend to claims which the creditor does not know or
suspect to exist in his favor at the time of  executing  the  release,  which if
known by him must have materially affected his settlement with the debtor."

         14. Counsel Waiver. Farney hereby acknowledges that he has been advised
to seek independent counsel with respect to this Agreement,  and has sought such
counsel,  and Farney also hereby consents to Nida & Maloney,  P.C.  representing
MRVT with respect to the  preparation  of this  Agreement.  Both MRVT and Farney
hereby  acknowledge that Nida & Maloney,  P.C. has provided  services to each of
the parties hereto.
