NOTES TO FINANCIAL STATEMENTS


(1)   Basis of Presentation-

         These   interim   Consolidated   Financial   Statements   of  Molecular
Biosystems,  Inc. and Subsidiaries (the "Company") should be read in conjunction
with the  Consolidated  Financial  Statements  of the Company and related  Notes
filed with the Company's Annual Report on Form 10-K for the year ended March 31,
1998.

         These interim Consolidated Financial Statements of the Company have not
been audited by independent public  accountants.  However, in the opinion of the
Company,  all  adjustments  required for a fair  presentation  of the  financial
position  of the  Company  as of  September  30,  1998,  and the  results of its
operations  for the six-months  ended  September 30, 1997 and 1998, and its cash
flows for the six-months  ended September 30, 1997 and 1998, have been made. The
results of operations for these interim periods are not  necessarily  indicative
of the operating results for the full year.


(2)   Commitments and Contingencies-

         In July, 1997 the Company and its marketing partner, Mallinckrodt, Inc.
("Mallinckrodt") filed suit (the "MBI Case") in United States District Court for
the  District  of  Columbia   against  four   potential   competitors   -  Sonus
Pharmaceuticals,   Inc.  ("Sonus"),   Nycomed  Imaging  AS  ("Nycomed"),   ImaRx
Pharmaceutical Corp. ("ImaRx") and its marketing partner DuPont Merck and Bracco
- - seeking  declarations that certain of their ultrasound  contrast agent patents
are invalid.

         The complaint  alleges that each of the defendants'  patents is invalid
on a variety of  independent  grounds  under U.S.  patent  law.  In  addition to
requesting  that  all of the  patents  in  question  be  declared  invalid,  the
complaint requests a declaration that, contrary to defendants' contentions,  the
Company and Mallinckrodt do not infringe the defendants'  patents, and asks that
defendants be enjoined from proceeding  against the Company and Mallinckrodt for
infringement until the status of defendants'  patents has been determined by the
court or the U.S.  Patent and Trademark  Office ("PTO").  The complaint  alleges
that each defendant has claimed or is likely to claim that its patent or patents
cover OPTISON(R), the Company's second generation  ultrasound  contrast agent,
and will attempt to prevent its commercialization.

         All of the  defendants  except  Nycomed  filed  motions to dismiss  the
complaint on jurisdictional  grounds.  In January 1998, the court dismissed each
of the defendants except Nycomed, ruling that the court lacked jurisdiction over
those defendants with respect to the Company's  claims of patent  invalidity and
non  infringement.  The court's ruling does not purport to rule on the merits of
the Company's claims; the dismissal was based solely on jurisdictional grounds.

         Following  Sonus's  dismissal  as a  defendant  in the MBI Case,  Sonus
activated a patent infringement lawsuit (the "Sonus Case") which it had filed in
August 1997 against the Company and  Mallinckrodt  in the United States District
Court for the Western  District of Washington.  Although the complaint was filed
in August  1997,  Sonus had agreed not to proceed  with the Sonus Case until the
jurisdictional  motions were decided in the MBI Case.  Sonus's complaint alleges
that the  manufacture  and  sale of  OPTISON  by the  Company  and  Mallinckrodt
infringe two patents owned by Sonus. As in the MBI Case, MBI  counterclaimed for
a  declaration  of  invalidity  and  non-infringement  with respect to the Sonus
patents.  These two  patents  are the same  patents  for which the  Company  was
seeking a declaration  of invalidity  in the MBI Case.  As discussed  below,  in
conjunction  with  the  reexamination  proceedings,  the PTO has  issued a final
rejection of all relevant claims of the patents  involved in the Sonus Case and
the MBI Case.

         Beginning in July 1997, the Company  received the first of five notices
from the PTO granting the  Company's  petitions for  reexamination  which it had
filed with respect to five patents held by three potential  competitors,  Sonus,
Nycomed and ImaRx.  Each of the five notices stated there was a substantial  new
question of patentability  raised by the Company's petitions with respect to all
claims of the  patents.  Each of the  patents  in the  reexamination  process is
related to the use of perfluorocarbon gases in ultrasound contrast agents and is
included  among the patents for which the Company was seeking a  declaration  of
invalidity  in the MBI Case (and for which the Company is  continuing  to seek a
declaration of invalidity in the case of Nycomed's patents).

         In  late  1997  and  early  1998,  the PTO  issued  office  actions  in
connection  with the  Company's  patent  reexamination  petitions  filed against
Sonus, Nycomed and ImaRx. The PTO office actions rejected all relevant claims of
these patents based on prior art not  previously  disclosed to the PTO by Sonus,
Nycomed or ImaRx during prosecution of their patent applications.  In June 1998,
the PTO issued a final rejection of all claims of the two Sonus patents involved
in the Sonus  Case.  In August  1998,  the PTO issued a final  rejection  of all
relevant  claims of the  Nycomed  patent  involved  in the MBI Case.  If the PTO
rejections are maintained on any appeal  subsequently filed by Sonus or Nycomed,
the patents which Sonus and Nycomed are attempting to assert against the Company
and  Mallinckrodt  to  block  the  manufacture  and  sale  of  OPTISON  will  be
invalidated.

         Litigation or administrative proceedings relating to these  matters
could result in a substantial cost to the Company;  and given the complexity of
the legal and factual issues,  the inherent  vicissitudes  and  uncertainty  of
litigation, and other factors, there can be no assurance of a favorable outcome.
An  unfavorable  outcome could have a material  adverse  effect on the Company's
business, financial condition and results of operations.  Moreover, there can be
no assurance that, in the event of an unfavorable outcome, the Company would be
able to obtain a license to any  proprietary rights that may be necessary to
commercialize OPTISON, either on acceptable terms or at all. If the Company were
required to obtain a license necessary to commercialize  OPTISON, the Company's
failure  or  inability  to do so would  have a  material adverse effect on the
Company's business, financial condition and results of operations.


(3)   Earnings per Share -

         In December 1997, the Company adopted Statement of Financial Accounting
Standards No. 128, "Earnings Per Share" (SFAS 128). The statement  specifies the
computation,  presentation,  and disclosure  requirements for earnings per share
(EPS). SFAS 128 requires  companies to compute net income (loss) per share under
two  different  methods,  basic and  diluted  per share data for all periods for
which an income statement is presented. Basic earnings per share was computed by
dividing  net income  (loss) by the  weighted  average  number of common  shares
outstanding during the period. Diluted earnings per share reflects the potential
dilution  that could  occur if net income were  divided by the  weighted-average
number of common  shares and  potential  common  shares from  outstanding  stock
options  for the  period.  Potential  common  shares  are  calculated  using the
treasury stock method and represent incremental shares issuable upon exercise of
the  Company's  outstanding  options.  For the  quarters  and six  months  ended
September  30, 1997 and 1998,  the diluted loss per share  calculation  excludes
effects of outstanding stock options as such inclusion would be anti-dilutive.


(4)   The Chugai Agreement -

         In April, 1998, the Company entered into a cooperative  development and
marketing  agreement with Chugai  Pharmaceutical  Co., Ltd. ("Chugai") of Japan.
The parties entered into this strategic alliance which covers Japan,  Taiwan and
South Korea,  to develop  OPTISON (which may be marketed under a different name)
and ORALEX(R), as well as related products. The Company granted Chugai an 
exclusive license to  develop,  manufacture,  and market  these  products
in the  subject territory, for which the Company received an up-front license
fee of $14 million in the first quarter of fiscal year 1999.

         With respect to licensed products  manufactured by Chugai,  Chugai will
pay the Company a royalty on net sales.  For licensed  products  manufactured by
the  Company,  the Company will  receive  royalties on net sales,  the amount of
which will depend upon the sales volume,  in addition to a transfer  price based
on average net sales per unit from the previous quarter.

         Additionally,  Chugai purchased  691,883 shares of the Company's common
stock at a premium of 40% over the  then-prevailing  market price.  This premium
was equal to $2.4 million and was  recognized as revenue in the first quarter of
fiscal year 1999. The equity investment was valued at $8.3 million.  The Company
is also  eligible to receive  milestone  payments of up to $20 million  based on
Chugai's  achievement of certain  Japanese  product  development  and regulatory
goals.

         The accompanying  consolidated statements of operations incorporate the
impact of the Chugai  transaction.  Pro forma unaudited  consolidated  operating
results of the  Company  for the six month  period  ended  September  30,  1998,
excluding  the  impact  of the  Chugai  transaction,  are  summarized  below (in

Item 2   - MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
           AND RESULTS OF OPERATIONS

         The  following  management  discussion  and analysis  should be read in
conjunction with (1) the current  Consolidated  Financial Statements and (2) the
Company's  Consolidated  Financial Statements and related Notes and Management's
Discussion and Analysis of Financial  Condition and Results of Operations in its
Annual Report on Form 10-K for the year ended March 31, 1998.


         From time to time, the Company may publish  forward-looking  statements
relating  to  such  matters  as  anticipated  financial  performance,   business
prospects,   technological  developments,  new  products,  regulatory  approval,
research and development  activities and similar  matters.  A variety of factors
could cause the Company's  actual  results and  experience to differ  materially
from the  Company's  anticipated  results or other  expectations.  The risks and
uncertainties  that may  affect the  operations,  performance,  development  and
results of the Company's  business include the expense and uncertain  outcome of
the  litigation  described  under the caption  "Recent  Events,"  including  the
possibility  of  injunctive  relief  to  competitors  prohibiting  the  sale  of
OPTISON(R);  a ruling by the Patent and Trademark Office ("PTO") in the pending
patent reexamination  proceedings favoring  competitors'  patents;  delays or an
inability  to bring  OPTISON  to market in Europe as a result of  regulatory
delays or  patent  litigation;  difficulties  and  delays  with  respect  to the
performance of clinical  trials;  delays by regulatory  authorities in approving
additional  indications for OPTISON,  including the evaluation of myocardial
perfusion;  manufacturing  problems;  difficulties  and delays  with  respect to
marketing  and  sales  activities;   general   uncertainties   accompanying  the
development and  introduction of new products;  and other risk factors  reported
from  time to time in the  Company's  reports  filed  with  the  Securities  and
Exchange Commission.


Recent Events

    In July,  1997 the Company and its  marketing  partner,  Mallinckrodt,  Inc.
("Mallinckrodt") filed suit (the "MBI Case") in United States District Court for
the  District  of  Columbia   against  four   potential   competitors   -  Sonus
Pharmaceuticals,   Inc.  ("Sonus"),   Nycomed  Imaging  AS  ("Nycomed"),   ImaRx
Pharmaceutical Corp. ("ImaRx") and its marketing partner DuPont Merck and Bracco
- - seeking  declarations that certain of their ultrasound  contrast agent patents
are invalid.

         The complaint  alleges that each of the defendants'  patents is invalid
on a variety of  independent  grounds  under U.S.  patent  law.  In  addition to
requesting  that  all of the  patents  in  question  be  declared  invalid,  the
complaint requests a declaration that, contrary to defendants' contentions,  the
Company and Mallinckrodt do not infringe the defendants'  patents, and asks that
defendants be enjoined from proceeding  against the Company and Mallinckrodt for
infringement until the status of defendants'  patents has been determined by the
court or the U.S.  Patent and Trademark  Office ("PTO").  The complaint  alleges
that each defendant has claimed or is likely to claim that its patent or patents
cover OPTISON,  the Company's second generation  ultrasound  contrast agent, and
will attempt to prevent its commercialization.

         All of the  defendants  except  Nycomed  filed  motions to dismiss  the
complaint on jurisdictional  grounds.  In January 1998, the court dismissed each
of the defendants except Nycomed, ruling that the court lacked jurisdiction over
those defendants with respect to the Company's  claims of patent  invalidity and
non  infringement.  The court's ruling does not purport to rule on the merits of
the Company's claims; the dismissal was based solely on jurisdictional grounds.

         Following  Sonus's  dismissal  as a  defendant  in the MBI Case,  Sonus
activated a patent infringement lawsuit (the "Sonus Case") which it had filed in
August 1997 against the Company and  Mallinckrodt  in the United States District
Court for the Western  District of Washington.  Although the complaint was filed
in August  1997,  Sonus had agreed not to proceed  with the Sonus Case until the
jurisdictional  motions were decided in the MBI Case.  Sonus's complaint alleges
that the  manufacture  and  sale of  OPTISON  by the  Company  and  Mallinckrodt
infringe two patents owned by Sonus. As in the MBI Case, MBI  counterclaimed for
a  declaration  of  invalidity  and  non-infringement  with respect to the Sonus
patents.  These two  patents  are the same  patents  for which the  Company  was
seeking a declaration  of invalidity  in the MBI Case.  As discussed  below,  in
conjunction  with  the  reexamination  proceedings,  the PTO has  issued a final
rejection of all relevant  claims of the patents  involved in the Sonus Case and
the MBI Case.

         Beginning in July 1997, the Company  received the first of five notices
from the PTO granting the  Company's  petitions for  reexamination  which it had
filed with respect to five patents held by three potential  competitors,  Sonus,
Nycomed and ImaRx.  Each of the five notices stated there was a substantial  new
question of patentability  raised by the Company's petitions with respect to all
claims of the  patents.  Each of the  patents  in the  reexamination  process is
related to the use of perfluorocarbon gases in ultrasound contrast agents and is
included  among the patents for which the Company was seeking a  declaration  of
invalidity  in the MBI Case (and for which the Company is  continuing  to seek a
declaration of invalidity in the case of Nycomed's patents).

         In  late  1997  and  early  1998,  the PTO  issued  office  actions  in
connection  with the  Company's  patent  reexamination  petitions  filed against
Sonus, Nycomed and ImaRx. The PTO office actions rejected all relevant claims of
these patents based on prior art not  previously  disclosed to the PTO by Sonus,
Nycomed or ImaRx during prosecution of their patent applications.  In June 1998,
the PTO issued a final rejection of all claims of the two Sonus patents involved
in the Sonus  Case.  In August  1998,  the PTO issued a final  rejection  of all
relevant  claims of the  Nycomed  patent  involved  in the MBI Case.  If the PTO
rejections are maintained on any appeal  subsequently filed by Sonus or Nycomed,
the patents which Sonus and Nycomed are attempting to assert against the Company
and  Mallinckrodt  to  block  the  manufacture  and  sale  of  OPTISON  will  be
invalidated.

         Litigation  or  administrative  proceedings  relating to these  matters
could result in a substantial  cost to the Company;  and given the complexity of
the legal and factual  issues,  the inherent  vicissitudes  and  uncertainty  of
litigation, and other factors, there can be no assurance of a favorable outcome.
An  unfavorable  outcome could have a material  adverse  effect on the Company's
business, financial condition and results of operations.  Moreover, there can be
no assurance that, in the event of an unfavorable  outcome, the Company would be
able to obtain a license to any  proprietary  rights  that may be  necessary  to
commercialize OPTISON, either on acceptable terms or at all. If the Company were
required to obtain a license necessary to commercialize  OPTISON,  the Company's
failure  or  inability  to do so would  have a  material  adverse  effect on the
Company's business, financial condition and results of operations.


Liquidity and Capital Resources

         At  September  30, 1998,  the Company had net working  capital of $21.7
million  compared to $21.1 million at March 31, 1998.  Cash,  cash  equivalents,
marketable  securities  and  certificates  of  deposit  were  $22.0  million  at
September 30, 1998 compared to $24.3 million at March 31, 1998. The cash balance
at  September  30, 1998 does not include  $6.4  million of the $22.3  million in
up-front  payments  due  from  Chugai,  which  will  be  received  in  quarterly
installments during the remainder of fiscal year 1999.

         For the next several years,  the Company  expects to incur  substantial
additional  expenditures  associated  with  product  development.   The  Company
anticipates  that its existing  resources,  including the proceeds of the public
offering in May 1996,  up-front license fees received from Chugai,  and interest
thereon, plus payments under its collaborative  agreements with Mallinckrodt and
Chugai,  will  enable the Company to fund its  operations  for at least the next
fifteen  months.  The  Company   continually  reviews  its  product  development
activities  in an effort to allocate its  resources to those  products  that the
Company believes have the greatest commercial  potential.  Factors considered by
the  Company in  determining  the  products to pursue may  include,  but are not
limited to, the projected markets, potential for regulatory approval,  technical
feasibility and estimated  costs to bring the product to the market.  Based upon
these factors,  the Company may from time to time reallocate its resources among
its product development activities.

         The Company may pursue a number of options to raise  additional  funds,
including borrowings; lease arrangements; collaborative research and development
arrangements with pharmaceutical  companies;  the licensing of product rights to
third  parties;   or  additional  public  and  private  financing,   as  capital
requirements  change as a result of strategic,  competitive,  technological  and
regulatory factors. There can be no assurance that funds from these sources will
be available on favorable terms, or at all.


Results of Operations

         Revenues Under Collaborative  Agreements.  Revenues under collaborative
agreements  were $1.2 million and $2.5 million for the three-month and six-month
periods  ended  September 30, 1998 compared to $1.3 million and $2.6 million for
the same  periods in the prior year.  These  revenues  in both years  consist of
quarterly  payments  to support  clinical  trials,  regulatory  submissions  and
product  development  received from  Mallinckrodt  under the  Company's  amended
agreement with Mallinckrodt which the Company entered into in September 1995.

         Product and Royalty Revenues. Revenues from product sales and royalties
were $1.4 million and $2.8 million for the  three-month  and  six-month  periods
ended September 30, 1998, compared to $100,000 and $300,000 for the same periods
in the prior year.  Product revenues come from the Company's sales of OPTISON to
Mallinckrodt  in the case of the quarter  ended  September 30, 1998 and from the
Company's  sales of ALBUNEX(R) to  Mallinckrodt in the case of the quarter ended
September  30, 1997.  Product  revenues  were  recognized  upon  shipment of the
product.

         The transfer price for the Company's  sales of OPTISON to  Mallinckrodt
is approximately  equal to 40% of Mallinckrodt's  average net sales price to its
end users of the  product for the  immediately  preceding  quarter.  Pursuant to
the Company's Amended and Restated Distribution Agreement ("ARDA"), the average
net sales price to end users is calculated by dividing the net sales for the
preceding  quarter  by the total  number of units  shipped to end users whether
paid for or shipped as samples. Consistent with industry practice, the  Company
considers  samples  a  marketing  expense  and as such the cost of samples is 
recorded as selling, general and administrative expense.

         The transfer price for the Company's  sales of ALBUNEX to  Mallinckrodt
was  determined  pursuant  to  ARDA  and  was  approximately  equal  to  40%  of
Mallinckrodt's average net sales price to its end users of the product.

         Although Mallinckrodt's sales of OPTISON have improved slightly in each
of the past two quarters, the Company anticipates that its sales to Mallinckrodt
will be reduced in the near term as Mallinckrodt manages its current inventory
of the product. The Company expects that revenues from sales of OPTISON for the
quarters ended December 31, 1998, and March 31, 1999, will be lower than 
revenues from sales of OPTISON for the quarters ended June 30, 1998, and
September 30, 1998. To address this issue, the Company is working with 
Mallinckrodt to increase the awareness of physicians and third party payors
about the benefits of OPTISON. The Company's expectation is based on
management's current judgment, which may change in the future based on numerous
potential events, including unanticipated increases in purchases of OPTISON by
end-users. As a result of the Company's reduced expectation for sales of 
OPTISON, the Company is actively evaluating cost reduction measures.  During its
fiscal third quarter the Company expects to finalize and to begin implementing
its cost reduction measures.

         Royalty  revenues  are  pursuant to a licensing  agreement  between the
Company and Abbott Laboratories.

         Costs of Products Sold.  Cost of products sold totaled $1.8 million and
$3.4 million for the three-month and six-month periods ended September 30, 1998,
resulting in a negative gross profit  margin.  This negative gross profit margin
was due to the fact that the current low levels of production  are  insufficient
to cover the  Company's  fixed  manufacturing  overhead  expenses.  For the same
quarter in the prior year,  cost of products  sold  totaled  $1.5  million.  The
Company  anticipates  an increase in its gross profit  margins as OPTISON  sales
volume increases.  The increase in sales volume will permit fixed costs included
in  manufacturing  overhead  to be  allocated  over a  larger  number  of  vials
produced.  Manufacturing  fixed costs are currently running at an annual rate of
approximately $5.5 million.  The amount of any increase in the Company's margins
and the time  required  by the  Company to  achieve  higher  margins  are highly
dependent on the market acceptance of OPTISON and are therefore uncertain.

         Research and  Development  Costs.  For the  three-month  and  six-month
periods ended September 30, 1998, the Company's  research and development  costs
totaled  $2.4  million and $4.6  million,  as compared to $2.7  million and $4.9
million for the same periods in fiscal year 1997.

         Selling, General and Administrative Expenses.  For the three-month and
six-month periods ended September 30, 1998, the Company's selling, general and 
administrative expenses totaled $5.7 million and $9.6 million, as compared to 
$2.8 million and $5.8 million for the same periods in fiscal year 1997.
This increase in the current year is primarily due to continuing legal expenses
and marketing costs associated with the launch of OPTISON.

         Other  Nonrecurring  Charges and Foreign Income Taxes.  Total operating
expenses for the three-month and six-month periods ended September 30, 1998 were
$10.0 million and $27.1  million  compared to $6.4 million and $13.1 million for
the same  periods in fiscal  year  1998.  The  increase  is  primarily  due to a
non-cash, non-recurring expense of $8.5 million related to the sale to Chugai of
territory rights previously reacquired from Shionogi.  Additionally, the company
paid $1.4 million in foreign taxes related to the Chugai alliance.

         Interest  Expense  and  Interest  Income.   Interest  expense  for  the
three-month and six-month  periods ended September 30, 1998 amounted to $154,000
and  $314,000,  compared to $186,000  and  $377,000  for the same periods in the
prior year,  and consisted of mortgage  interest on the Company's  manufacturing
building and interest on a note payable which is secured by the tangible  assets
of the Company. The interest rate on the mortgage was 8% in September 1998.

         The terms of the note  payable  were  renegotiated  during the  current
quarter. Prior to this revision,  interest on the note payable was calculated at
prime  plus 1%,  equal to 9.5% in  September,  1998,  and the note  payable  was
secured by a $3 million pledged certificate of deposit.  Effective September 18,
1998,  interest on the loan was reduced to prime and the pledged  certificate of
deposit was released as collateral.  The note is payable in monthly installments
of principal plus interest over five years.

         Interest  income  for  the  three-month  and  six-month  periods  ended
September  30, 1998 was  $370,000  and  $795,000  compared to $540,000  and $1.2
million for the same periods in the prior year. The decrease in interest  income
in the  current  year is due to lower  average  cash and  marketable  securities
balances.  The  Company's  cash  is  invested  primarily  in  short-term,  fixed
principal investments,  such as U.S. Government agency issues,  corporate bonds,
certificates of deposit and commercial paper.

         Pro forma Results.  See Note 4 in Notes to the Financial Statements for
a  discussion  of  quarterly   results   excluding  the  impact  of  the  Chugai
transaction.


         Year 2000 Readiness.  The Year 2000 problem is the result of computer
programs being written using two digits rather than four digits to define the
applicable  year. Any of the Company's  programs that have  time-sensitive
software may recognize a date using "00" as the year 1900  rather than the
year 2000.  This could  result in a major  system  failure  or  miscalculations,
which  could  disrupt  operations, including product development, manufacturing,
the processing of transactions and other  normal  business  activities.  The
Year  2000  problem  may  also  create unforeseen risks to the Company from its
internal  computing  systems as well as from computer systems of third parties
with which it deals.

         The Company has conducted a  comprehensive  review of its information
technology ("IT") and non information technology ("Non-IT") systems to identify
the systems that could be affected by the "Year 2000" issue and has  developed
a plan to assess and resolve Year 2000  problems  with its IT and Non-IT 
systems.  The plan  includes  five  phases:  inventory,  assessment, evaluation,
implementation and testing. The Company has completed the inventory phase on its
IT  systems  and has  identified  all IT systems  that the  Company believes are
at risk. The Company is in the process of  inventorying  its Non-IT systems and
expects to have  identified  all Non-IT  systems  that are at risk within the
next few months.

         The  Company  has  already  initiated  the  assessment  phase (in which
systems that were  inventoried are prioritized) on the IT-Systems and expects to
start on the Non-IT systems in the very near future.  The Company estimates that
the  assessment  phase for all  systems  should be  complete  by  January  1999.
Immediately following completion of the assessment phase, the Company will begin
the evaluation phase which involves testing systems and determining which IT and
Non IT systems need to be replaced, repaired or retired. The evaluation phase is
expected to take approximately 3 months.

         Once the  evaluation  phase is  complete,  the  Company  will begin the
implementation  phase and repair/replace  all noncompliant  systems (both IT and
Non-IT),  convert  data as  necessary,  and obtain  compliance  statements.  The
implementation  phase is  expected  to take  three to four  months to  complete.
Finally,  the Company will test and validate  the repaired  noncompliant  IT and
Non-IT  systems for  compliance.  This final phase of the process  should take 3
months and should be complete by October 1999.

         In   addition,   the  Company  is  in  the  process  of   conducting  a
comprehensive  review of its vendors,  service  providers  (including  financial
institutions and insurance companies), and collaborative partners. Although this
assessment  is not yet  complete,  the  Company  is not  currently  aware of any
material Year 2000 issues with respect to its dealings with such third  parties.
However,  if the Company  discovers  Year 2000 problems with such third parties'
systems,  the Company  will be unable to control  whether its current and future
suppliers',  service providers' or collaborative partners' systems are Year 2000
compliant.  To the extent that such third parties would be hindered by Year 2000
problems, the Company's operations could be materially adversely affected.

         The Company  anticipates that its assessment of both internal and third
party IT and Non-IT  systems will be complete by October 31, 1999. At this time,
the  Company  believes  that the Year  2000  problem  will not pose  significant
operational  problems  for the  Company's  computer  systems.  The Company  also
expects  that the total  costs  required  to fix the Year 2000  problem  will be
immaterial.  To date,  the Company has not used,  and does not plan to use,  any
independent verification and validation process to assess the reliability of the
Company's risk and cost estimates.  Since no significant issues have arisen, the
Company does not have a contingency plan to address any material 2000 issues. If
significant  Year  2000  issues  arise,  the  Company  may not be able to timely
develop and implement a contingency  plan and the Company's  operations could be
adversely affected.


Prospective Information

         Although Mallinckrodt's sales of OPTISON have improved slightly in each
of the past two quarters, the Company anticipates that its sales to Mallinckrodt
will be reduced in the near term as Mallinckrodt manages its current inventory
of the product. The Company expects that revenues from sales of OPTISON for the
quarters ended December 31, 1998, and March 31, 1999, will be lower than 
revenues from sales of OPTISON for the quarters ended June 30, 1998, and
September 30, 1998. To address this issue, the Company is working with 
Mallinckrodt to increase the awareness of physicians and third party payors
about the benefits of OPTISON. The Company's expectation is based on
management's current judgment, which may change in the future based on numerous
potential events, including unanticipated increases in purchases of OPTISON by
end-users. As a result of the Company's reduced expectation for sales of 
OPTISON, the Company is actively evaluating cost reduction measures.  During its
fiscal third quarter the Company expects to finalize and to begin implementing
its cost reduction measures.


         The Company is involved in several legal and administrative proceedings
which could result in a substantial cost to the Company. Given the complexity of
the legal and factual issues and the uncertainty of litigation,  there can be no
assurance of a favorable outcome.  An unfavorable  outcome could have a material
adverse  effect on the Company's  business,  financial  condition and results of
operations. For a detailed discussion of these matters, see "Recent Events."
