                    Salomon Smith Barney Inc. Account Number

Note:           This Account Control Agreement (the "Agreement") is subject
                to the review and acceptance by Salomon Smith Barney, Inc.

To:             Salomon Smith Barney Inc. ("Salomon Smith Barney"),
                Security Intermediary

Date:           October 27, 1999

Gentlemen:

     The   undersigned,   MICHAEL  D.  FARNEY  and  SALLY  FARNEY   (hereinafter
collectively,  the "Pledgor"),  and MIRAVANT MEDICAL TECHNOLOGIES  (hereinafter,
the  "Pledgee"),  entered into a Stock Pledge  Agreement  dated October 27, 1999
(the "Security  Agreement") as amended pursuant to which a security  interest in
all  present  and future  assets (as  hereinafter  defined)  in the  Account (as
hereinafter  defined)  of the  Pledgor are granted by the Pledgor to the Pledgee
(the "Pledge"). In connection therewith, the Pledgor hereby instructs you to:

     1. establish a cash securities  account,  which is to be known as "MIRAVANT
MEDICAL  TECHNOLOGIES  Secured Party,  f/b/o MICHAEL D. FARNEY and SALLY FARNEY"
(the "Account");


     2.  place  the  assets,   including  all  financial   assets,   securities,
entitlements  and all other assets now or  hereinafter  received in such Account
(together, the "Assets") including,  without limitation,  those assets listed in
Exhibit A attached hereto and made a part hereof,  into the Account.  The Assets
are pledged  according  to the terms of the Security  Agreement.  As long as the
Assets are  pledged to the  Pledgee,  Salomon  Smith  Barney will not invade the
Assets to cover  margin  debits or calls in any other  accounts of the  Pledgor;
Salomon Smith Barney agrees that,  except for liens resulting from  commissions,
fees or charges based upon  transactions  in the Account  pursuant to its Client
Agreement with the Pledgor, it subordinates in favor of the Pledgee any security
interest,  lien  or  right  of  setoff  that  Salomon  Smith  Barney  may  have,
acknowledges  that neither it, its  subsidiaries  or its  affiliates has or will
assert a lien on the Assets, and acknowledges that it has not received notice of
any other  security  interest  in such  Assets.  In the event any such notice is
received,  Salomon  Smith Barney will promptly  notify the Pledgee.  The Pledgor
herein   represents  that  the  Assets  are  free  and  clear  of  any  lien  or
encumbrances,  and agrees that,  with the  exception  of the  security  interest
granted herein, no further or additional liens or encumbrances will be placed on
the Assets without the express  written  consent of both the Pledgee and Salomon
Smith Barney;

     3. maintain the Assets  pledged as described in Exhibit A attached  hereto,
or the proceeds from the sale of such Assets,  together with any income  derived
therefrom,  except that the Pledgee and the Pledgor  acknowledge  and agree that
Salomon Smith Barney shall not be held responsible for any market decline in the
market value of the Assets,  or to notify the Pledgee or the Pledgor of any such
decline in the market value of the Assets,  or to take any action with regard to
such Assets, except upon the specific written directions stated herein;

     4. provide to the  Pledgee,  so long as this  Agreement  remains in effect,
with a  duplicate  copy to the  Pledgor,  a monthly  statement  of Assets  and a
confirmation  statement of each  transaction  effected in the Account after such
transaction is effected.

     The Pledgor directs  Salomon Smith Barney to sell the Assets,  as described
in  Exhibit B hereto  (the  "Pledgor's  Instructions").  The  Pledgor  shall not
instruct  Salomon Smith Barney to deliver and,  except as may be required by law
or  by  Court  Order,  Salomon  Smith  Barney  shall  not  deliver  cash  and/or
securities,  or proceeds from the sale of, or distributions  on, such securities
out of the Account to the Pledgor or to any other person or entity except to the
Pledgee. Salomon Smith Barney shall comply with the Pledgor's Instructions,  and
no other instructions of the Pledgor,  without the consent of the Pledgee or any
other person (it being  understood  and agreed that  Salomon  Smith Barney shall
have no duty or obligation whatsoever of any kind or character to have knowledge
of the terms of the Security  Agreement or to determine  whether or not an event
of default  exists).  The Pledgor  hereby  agrees to indemnify and hold harmless
Salomon Smith Barney,  its  affiliates,  officers and employees from and against
any and all claims,  causes of action,  liabilities,  lawsuits,  demands  and/or
damages,  including,  without limitation, any and all court costs and reasonable
attorneys'  fees,  that may result by reason of Salomon  Smith Barney  complying
with such instructions of the Pledgor. In the event that Salomon Smith Barney is
sued or  becomes  involved  in  litigation  as a result  of  complying  with the
Pledgor's  Instructions,  the Pledgor and the Pledgee  agree that Salomon  Smith
Barney  shall  be  entitled  to  charge  all the  costs  and fees it  incurs  in
connection  with such  litigation  to the Assets in the  Account and to withdraw
such sums as the costs and charges accrue.

     The Pledgee shall have no liabilities, of any kind or nature, in connection
with the  execution  of the  Pledgor's  Instructions.  The  Pledgee  shall  only
indemnify  Salomon Smith Barney from any claims,  suits,  liabilities or damages
which may result from Salomon Smith Barney  complying with any  instructions  of
the Pledgee,  which the Pledgee shall subsequently deliver in writing to Salomon
Smith Barney.

     Except with respect to the obligations and duties as set forth herein, this
Agreement  shall not impose or create any  obligations  or duties  upon  Salomon
Smith Barney greater than or in addition to the customary and usual  obligations
and duties of Salomon Smith Barney to the Pledgor.

     This Agreement shall be binding upon and inure to the benefit of the heirs,
successors and assigns of the  respective  parties hereto and shall be construed
in  accordance  with the laws of the  State of New York  without  regard  to its
conflict of law  principles  and the rights and remedies of the parties shall be
determined in accordance with such laws.

     Salomon  Smith  Barney will treat all  property at any time held by Salomon
Smith  Barney  in  the  Account  as  financial  Assets.   Salomon  Smith  Barney
acknowledges  that this Agreement  constitutes  written  notification to Salomon
Smith Barney, pursuant to Articles 8 and 9 of the Uniform Commercial Code of the
State of New  York,  and any  applicable  federal  regulations  for the  Federal
Reserve Book Entry System, of the Pledgee's security interest in the Assets. The
Pledgor,  the Pledgee  and Salomon  Smith  Barney  also are  entering  into this
Agreement  to  perfect  and  confirm  the first and  exclusive  priority  of the
Pledgee's  security  interest  in the Assets.  Salomon  Smith  Barney  agrees to
promptly make and thereafter  maintain all necessary entries or notations in its
books and records to reflect the Pledgee's security interest in the Assets.

     If any term or provision of this  Agreement is  determined to be invalid or
unenforceable,  the  remainder  of this  Agreement  shall  be  construed  in all
respects as if the invalid or unenforceable term or provision were omitted. This
Agreement  may not be  altered or amended  in any  manner  without  the  express
written  consent of the  Pledgor,  the Pledgee and Salomon  Smith  Barney.  This
Agreement  may be  executed  in any number of  counterparts,  all of which shall
constitute one original agreement.

     This  Agreement  may be terminated by Salomon Smith Barney upon thirty (30)
days'  written  notice to the Pledgor and the Pledgee.  Upon  expiration of such
thirty  (30) day  period,  Salomon  Smith  Barney  shall  be  under  no  further
obligation  except to hold the pledged  Assets in  accordance  with the terms of
this Agreement, pending receipt of written instructions from the Pledgor and the
Pledgee, jointly regarding the further disposition of the pledged Assets.

     The Pledgor and the Pledgee acknowledge that this Agreement supplements the
Pledgor's existing Client  Agreement(s) with Salomon Smith Barney and, except as
expressly  provided herein, in no way is this Agreement  intended to abridge any
rights that Salomon Smith Barney might otherwise have.


     IN WITNESS WHEREOF,  the Pledgor and the Pledgee have caused this Agreement
to be executed by their duly  authorized  officers all as of the day first above
written.
