MANAGEMENT'S DISCUSSION AND ANALYSIS
OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS


(REFERENCES TO YEARS ARE TO THE COMPANY'S FISCAL YEARS ENDED MARCH 31.) EXCEPT
FOR THE HISTORICAL INFORMATION CONTAINED HEREIN, THE FOLLOWING DISCUSSION
CONTAINS FORWARD-LOOKING STATEMENTS THAT INVOLVE RISKS AND UNCERTAINTIES. THE
COMPANY'S ACTUAL RESULTS COULD DIFFER MATERIALLY FROM THOSE DISCUSSED HERE.


OVERVIEW

The Company is a world leader in the development, manufacture and sale of
ultrasound contrast imaging agents. ALBUNEX-Registered Trademark-, the Company's
first-generation ultrasound contrast agent, was first approved for sale in Japan
in October 1993 and in the United States in August 1994 for the assessment of
cardiac function. The Company believes that sales of ALBUNEX have been below the
Company's original expectations due primarily to the short length of time that
ALBUNEX microspheres remain intact in the bloodstream and the lack of clinical
data to support the Company's belief that the use of ALBUNEX can reduce
healthcare costs through the avoidance of more expensive diagnostic procedures.
Mallinckrodt, the Company's principal marketing partner, has begun a post-
approval clinical study in 1996 designed to demonstrate the cost-effectiveness
of ALBUNEX for stress echocardiograms and has completed Phase 3 clinical trials
for a second indication for ALBUNEX, the assessment of fallopian tube patency,
in order to broaden the potential uses of the product.

While ALBUNEX represents a major breakthrough in ultrasound imaging because it
improves visualization of the left side of the heart, the potential markets for
ALBUNEX are limited because of the short duration of ALBUNEX in the bloodstream.
This short duration prevents the use of ALBUNEX for the assessment of myocardial
perfusion (blood flow in the heart muscle). The Company believes that myocardial
perfusion has a significantly greater market potential than cardiac function,
and accordingly, the Company is focusing its product development activities on
FS069, the Company's second-generation ultrasound contrast agent which remains
intact in the bloodstream for a much longer period of time. Clinical studies to
date suggest that FS069 may be effective for the assessment of both cardiac
function and myocardial perfusion.

The Company does not foresee ALBUNEX sales alone as resulting in profitable
operations for the Company. Operating losses may occur for at least the next
several years due to continued requirements for research and development
including preclinical testing and clinical trials, regulatory activities and the
costs of commercializing new products. The magnitude of the losses and the time
required by the Company to achieve profitability are highly dependent on the
market acceptance of ALBUNEX and the regulatory approval and market acceptance
of FS069 and are therefore uncertain. There can be no assurance that the Company
will be able to achieve profitability on a sustained basis or at all. Results of
operations may vary significantly from quarter to quarter depending on, among
other things, the progress, if any, of the Company's research and development
efforts, the timing of milestone payments, the timing of certain expenses and
the establishment of collaborative research agreements.


REVENUE RECOGNITION

Historically the Company has earned revenues from three sources: revenues under
collaborative agreements, product revenues and license fee revenues. See Note 1
of Notes to the Consolidated Financial Statements.

REVENUES UNDER COLLABORATIVE AGREEMENTS  Revenues under collaborative agreements
have been the primary source of revenues for the Company in the past. They
consist of three types of revenues: (i) milestone payments which are earned on
the achievement of certain product development and territorial milestones; (ii)
payments received from Mallinckrodt under the Company's amended agreement to
support clinical trials, regulatory submissions and product development; and
(iii) a bonus paid by Mallinckrodt equivalent to Mallinckrodt's first year
product sales of ALBUNEX at its sales price to end users of the product.

PRODUCT REVENUES  Product revenues are based upon MBI's sales to Mallinckrodt
and Shionogi and are recognized upon shipment of the product. The transfer
prices for MBI's sales of ALBUNEX-Registered Trademark- to Mallinckrodt and
Shionogi are determined under the respective agreements and are equal to 40% of
Mallinckrodt's net sales price to its end users of the product and 30% of
Shionogi's net sales price to its end users.



LICENSE FEES  License fees are recognized at the time of receipt and are
generally received in connection with the grant of product development,
marketing and/or distribution rights to one of the Company's technologies.


RESULTS OF OPERATIONS

FISCAL YEAR 1996 COMPARED TO FISCAL YEAR 1995  Revenues under collaborative 
agreements were $2.4 million for the fiscal year ended March 31, 1996, 
compared to $15.1 million for the fiscal year ended March 31, 1995. This 
decrease was due primarily to non-recurring milestones earned in fiscal year 
1995 associated with receiving approval to market ALBUNEX in the United 
States and the release of ALBUNEX to Mallinckrodt's sales force. For fiscal 
year 1996, $2.0 million of the revenues under collaborative agreements was 
attributable to the receipt of the first two quarterly payments from 
Mallinckrodt to support clinical trials, related regulatory submissions and 
associated product development (discussed above under "Revenues Under 
Collaborative Agreements" and below under "Liquidity and Capital Resources"). 
The remaining $412,000 for fiscal year 1996 was the first year's sales bonus 
which Mallinckrodt agreed to pay to MBI (discussed above under "Revenues 
Under Collaborative Agreements").

Product revenues were $647,000 for fiscal year 1996, compared to $1.8 million
for the prior year. The majority of this decrease was due to greater product
shipments in the prior year as a result of receiving the initial approval to
market ALBUNEX in the United States and the initial release of the product to
Mallinckrodt's sales force.

License fees were $25,000 in fiscal year 1996, compared to $40,000 in fiscal
year 1995. These fees were the result of a non-exclusive license entered into in
fiscal year 1993 granting rights for certain of the Company's patents which it
is no longer exploiting. The Company received an initial license fee of $250,000
in fiscal year 1993 and continues to receive an annual license maintenance fee.

Cost of products sold totaled $1.6 million for fiscal year 1996, resulting in a
negative gross profit margin. This was due to the fact that the current low
levels of production were insufficient to cover the Company's fixed
manufacturing overhead expenses. For fiscal year 1995, cost of products sold
totaled $1.6 million, resulting in a gross profit margin of 9.1%. Prior
to the approval of ALBUNEX by the FDA, certain expenses associated with the
manufacturing of the product had been recorded as research and development
costs. The Company anticipates an increase in its gross profit margins at such
time as ALBUNEX sales volume increases and thus the fixed costs included in
manufacturing overhead will be allocated over a larger number of vials produced.
The amount of any increase and the time required by the Company to achieve
higher  margins are highly dependent on the market acceptance of ALBUNEX and are
therefore uncertain.

The Company's research and development costs totaled $13.6 million for the year
ended March 31, 1996, as compared to $18.7 million for the year ended March 31,
1995. This decrease of 27% in the current year is due in large part to the
decision the Company made in February 1995 to focus its research and development
efforts primarily on its ultrasound contrast agents and to reduce its staffing
by 25% or 47 employees. This decision was made to reduce the Company's cash burn
rate and additionally focus the Company on those markets where it felt it would
earn the greatest return on its invested capital. As a result, the Company
discontinued research on non-ultrasound products and terminated those employees
who worked on these projects along with corresponding reductions in
administrative staffing.

Selling, general and administrative expenses totaled $5.9 million in fiscal year
1996 and were substantially unchanged from the prior fiscal year.

During fiscal year 1996, the Company's other expenses totaled $3.1 million as
compared to $3.4 million for the prior year. In the current year, the Company
recorded the following charges: $1.4 million related to legal settlements and
related costs; $1.0 million related to the write-off of license fees related to
technologies no longer being developed; and $667,000 due to the write-down of
real estate which was sold in March 1996. The legal settlement and related costs
were the result of the Bracco arbitration. See Note 6 of Notes to the
Consolidated Financial Statements. In November 1995, the Company entered into a
contract for the sale of the two buildings and underlying land that the Company
purchased in December 1993. In anticipation of the sale, the Company wrote-down
the carrying value of the buildings by $667,000 to the net amount that
it then expected to receive from the sale. The sale of the buildings was
completed in March 1996 for $6.5 million after deducting costs related to the
sale. During fiscal year 1995, the Company received a bonus from Mallinckrodt of
approximately



MBI  FINANCIAL REVIEW


$3.0 million related to the approval of ALBUNEX-Registered Trademark- for
marketing in the United States. Under the terms of the distribution agreement
with Mallinckrodt, this bonus was awarded to MBI's employees. As a result, the
Company recorded a charge of approximately $3.0 million, included under other
expenses. Of this amount, approximately $1.7 million was paid in cash, and the
balance represented forgiveness of indebtedness.

Interest expense for fiscal years 1996 and 1995 amounted to $786,000 and
$694,000, respectively, and consisted primarily of mortgage interest on the
Company's manufacturing building. Interest expense increased $92,000 during the
current year due to a loan that the Company obtained in May 1994 to finance the
purchase of two unimproved buildings and underlying land in December 1993. In
March 1996, the loan was restructured into a new note payable in the amount of
$6.0 million which bears interest at prime plus 1% and is payable in monthly
installments of principal plus interest over five years. The interest rate on
the note was 9.25% in March 1996.

Interest income for fiscal years 1996 and 1995 was $1.1 million and $1.2
million, respectively. The decrease in interest income in the current year is
due to lower average cash and marketable securities balances.

No tax benefit has been recognized for fiscal years 1996 or 1995 as the Company
had fully utilized its operating loss carryback ability in fiscal year 1993. As
of March 31, 1996, the Company had federal and state operating loss
carryforwards of approximately $71.1 million and $34.6 million, respectively,
and realization of future tax benefits from utilization of net
operating loss carryforwards is uncertain.

FISCAL YEAR 1995 COMPARED TO FISCAL YEAR 1994  Revenues under collaborative
agreements were $15.1 million during the fiscal year ended March 31, 1995 as
compared to $5.7 million for the fiscal year ended March 31, 1994. Revenues in
both years were the result of milestone payments primarily due to the marketing
approval of ALBUNEX in the United States in fiscal year 1995 and in Japan in
fiscal year 1994. Of the fiscal 1995 total, $11.8 million were milestone
payments which resulted from the marketing approval of ALBUNEX in the United
States in July 1994 and approximately $3.0 million resulted from the first
commercial shipment of ALBUNEX in the United States in October 1994. The
remaining $345,000 was the first year's sales bonus which Mallinckrodt agreed to
pay to MBI (discussed above under "Revenues Under Collaborative Agreements"). Of
the milestones received for the marketing approval of ALBUNEX, approximately
$3.0 million was awarded to company employees as provided in the Company's
distribution agreement with Mallinckrodt. Included in fiscal year 1995 are both
the income and the offsetting expense associated with the receipt from
Mallinckrodt and the subsequent award to employees of these bonuses. The expense
related to this distribution is included under other expenses. For fiscal year
1994, the revenues under collaborative agreements were all earned under the
Shionogi agreement and consisted primarily of milestone payments ($5.0 million)
associated with receiving approval to market ALBUNEX in Japan in October 1993.

Product revenues were $1.8 million for fiscal year 1995, compared to $1.1
million in the prior year. Product revenues in fiscal year 1995 include $1.1
million earned from Mallinckrodt since the first commercial shipment of ALBUNEX
in the United States in October 1994. The remainder of product revenues in
fiscal years 1994 and 1995 consist of sales to Shionogi.

License fees were $40,000 for fiscal year 1995, compared to approximately 
$2.0 million in fiscal year 1994. License fee revenues in fiscal year 1994 
include $2.0 million earned in connection with a license agreement granting 
exclusive marketing and distribution rights for the Company's oral ultrasound 
agent in Europe. See Note 6 of Notes to the Consolidated Financial 
Statements. The fees in fiscal year 1995 were royalties related to a 
non-exclusive license entered into in fiscal year 1993 granting rights for 
certain of the Company's patents which it is no longer exploiting.

In fiscal years 1995 and 1994 cost of products sold totaled $1.6 million and
$580,000, resulting in gross profit margins of 10% and 45%, respectively. The
decrease in gross profit margin percentage is due to the higher proportion of
United States sales in 1995 which are currently at a negative margin due to the
high amount of fixed overhead and low amount of production volume. Additionally,
the gross profit margin for ALBUNEX sales in Japan is higher due to the higher
Japanese sales price per unit volume.

Research and development costs in fiscal year 1995 remained substantially
unchanged from fiscal year 1994. Increases in preclinical trials expenses and
the amortization of license fees paid by the Company were offset by a decrease
in compensation. Increased preclinical trials costs resulted primarily from
studies done for FS069. License fee amortization, which is calculated by using
the ratio of current contract revenues earned to total expected contract
revenues related to the licensed products, increased as a result of increased
ALBUNEX-Registered Trademark- development milestones during the year.

Selling, general and administrative expenses in fiscal year 1995 amounted to
$5.9 million and was substantially unchanged from the fiscal year 1994 total of
$5.7 million.

During fiscal year 1995, the Company received a bonus from Mallinckrodt of
approximately $3.0 million related to the approval of ALBUNEX for marketing in
the United States. Under the terms of the distribution agreement with
Mallinckrodt, this bonus was awarded to MBI's employees. As a result, the
Company recorded a charge of approximately $3.0 million, included under other
expenses. Of this amount, approximately $1.7 million was paid in cash, and the
balance represented forgiveness of indebtedness. Additionally, in fiscal year
1994, the Company agreed without admitting liability to the settlement of a
class action complaint against the Company. The Company agreed to pay $3.0
million in cash (of which the Company's directors and officers liability insurer
contributed $800,000), and shares of the Company's Common Stock worth $1.5
million (172,414 shares valued at the time of distribution, March 31, 1995) into
a settlement fund. The expense related to this settlement and its related costs
is included under other expenses in fiscal year 1994.

Interest expense for fiscal years 1995 and 1994 amounted to $694,000 and
$327,000, respectively. Interest expense increased in fiscal year 1995 owing to
a note payable which the Company entered into in May 1994 to finance the
purchase of two unimproved buildings and underlying land in December 1993. The
remainder of the interest in both years consists
of mortgage interest on the Company's manufacturing building.

The decrease in interest income, from $1.9 million in fiscal year 1994 to $1.2
million in fiscal year 1995 was due to lower average cash and marketable
securities balances as well as lower interest rates.

No tax benefit has been recognized in fiscal years 1995 or 1994 as the Company
had fully utilized its operating loss carryback ability in fiscal year 1993. As
of March 31, 1995, the Company had federal and state operating loss
carryforwards of approximately $53.3 million and $25.4 million, respectively,
and realization of future tax benefits from utilization of net
operating loss carryforwards is uncertain.


LIQUIDITY AND CAPITAL RESOURCES

Subsequent to the Company's fiscal year end, on May 30, 1996, the Company
completed a follow-on public offering of 4.1 million shares of Common Stock at
$9.00 per share. Net proceeds from this offering (after deducting underwriting
discounts and commissions, but before estimated offering expenses) amounted to
approximately $34.6 million. The Company's net working capital at March 31,
1996, adjusted to reflect the receipt of these proceeds, would have been $53.2
million including cash, cash equivalents and marketable securities of $55.2
million.

On September 7, 1995, the Company entered into an amended and restated 
distribution agreement and a related investment agreement with Mallinckrodt 
which will provide the Company with between $33.0 million and $47.5 million. 
Under the terms of the agreement, Mallinckrodt is obligated to make payments 
to the Company totaling $20.0 million over four years to support clinical 
trials, related regulatory submissions and associated product development of 
the licensed products, which include, but are not limited to, ALBUNEX and 
FS069. These payments will be made in 16 quarterly installments of $1.0 
million for the first four quarters, $1.25 million for the following eight 
quarters and $1.5 million for the final four quarters. The payments may be 
accelerated in the event that the Company's cumulative outlays for clinical 
trials are in excess of the amounts received at any point in time. However, 
the quarterly payments may not be postponed. The first three quarterly 
payments have been received by the Company.

The amended distribution agreement also provides for potential payments to the
Company of up to $14.5 million upon the satisfaction of certain territorial and
product development milestones. There can be no assurance, however, that all or
any of these milestones will be met.

MBI  FINANCIAL REVIEW

In connection with the amended distribution agreement, the Company also entered
into an investment agreement on September 7, 1995, whereby Mallinckrodt made an
equity investment in the Company by purchasing 1,118,761 unregistered shares of
Common Stock for $13.0 million. The price paid by Mallinckrodt, $11.62 per share
before related costs, represented a 40% premium over the then-prevailing market
price.

Capital expenditures for facilities, laboratory equipment, furniture and
fixtures were $2.4 million, $2.5 million and $8.2 million for fiscal years 1996,
1995 and 1994, respectively. The fiscal year 1994 expenditures consisted
primarily of the purchase of two unimproved buildings and the underlying land
for $7.1 million. The fiscal years 1996 and 1995 expenditures consisted
primarily of building improvements and equipment for aseptic manufacturing
facilities being constructed for the manufacture of ALBUNEX-Registered
Trademark- and other products. The Company sold the two unimproved buildings
purchased in December 1993. The sale of the buildings was completed in March
1996 for approximately $6.5 million after deducting costs related to the sale.
Approximately $4.6 million of the proceeds from the sale was used to pay a note
payable, which was subsequently replaced with a $6.0 million note discussed
below, and the remainder was added into the Company's working capital.

In March 1996, the Company entered into a note payable with a bank for $6.0
million. The loan bears interest at a variable rate based upon the bank's prime
rate plus one percent and is payable in monthly installments of $100,000 plus
accrued interest through March 2001. The loan contains covenants relating to
cash flow coverage, minimum cash balances and requires a compensating balance of
$3.0 million. The loan is secured by the tangible assets of the Company.

The Company is currently engaged in a dispute with Shionogi. In April 1996, 
the Company and Shionogi filed cross-demands for arbitration of their 
respective claims against each other. The Company is seeking in excess of $45 
million in compensatory and consequential damages plus punitive damages for 
Shionogi's breach of the MBI-Shionogi license and cooperative development 
agreement. Shionogi is seeking in excess of $37 million plus punitive damages 
on its claim that MBI has breached the agreement. The Company's dispute with 
Shionogi may have the effect of interrupting or suspending sales of ALBUNEX 
in Japan (approximately $264,000 in revenue to the Company for fiscal year 
1996), of further delaying the marketing of ALBUNEX in South Korea and 
Taiwan, and of further delaying the development of FS069 throughout 
Shionogi's territory, and carries with it the risk of monetary damages being 
awarded against the Company. See Note 6 of Notes to the Consolidated 
Financial Statements.

The Company currently leases one of its operating facilities in San Diego. The
lease requires aggregate payments of approximately $3.9 million through fiscal
year 2003.

At March 31, 1996, the Company had net working capital of $18.6 million compared
to $20.9 million at March 31, 1995. Cash, cash equivalents and marketable
securities were $20.6 million at March 31, 1996 compared to $19.7 million at
March 31, 1995. 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
offering noted above and interest thereon, plus payments under its existing
collaborative agreements, will enable the Company to fund its operations for at
least the next 24 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, if at all.

The Company believes that inflation and changing prices have not had a material
effect on operations for fiscal years 1996, 1995 and 1994 and that the impact of
government regulation on the Company is not materially different from the impact
on other similar enterprises.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


NOTE 1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

DESCRIPTION OF BUSINESS  Molecular Biosystems, Inc. ("MBI" or the "Company")
discovers, develops and manufactures proprietary diagnostic ultrasound imaging
agents. The Company's continuing operations have been unprofitable since 1992.
The Company does not foresee product revenues from sales of ALBUNEX , the
Company's first product and the first ultrasound imaging agent available in the
United States, as resulting in profitable operations for the Company. Operating
losses may occur for at least the next several years due to continued
requirements for research and development, including preclinical testing and
clinical trials, regulatory activities and the high costs of commercialization
activities. The magnitude of the losses and the time required by the Company to
achieve profitability are highly dependent on the market acceptance of ALBUNEX
and the regulatory approval and market acceptance of FS069, the Company's second
generation agent and are therefore uncertain. There is no assurance that the
Company will be able to achieve profitability on a sustained basis or at all.

PRINCIPLES OF CONSOLIDATION  The Consolidated Financial Statements include the
accounts of Molecular Biosystems, Inc. and its wholly owned subsidiaries,
Syngene, Inc. and Scan Pharmaceuticals, Inc. Syngene Inc. and Scan
Pharmaceuticals, Inc. are currently inactive corporations. All significant
intercompany accounts and transactions have been eliminated. 

Certain amounts in the prior years' financial statements and notes have been
reclassified to conform with the current year presentation.

USE OF ESTIMATES  The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and 
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the reported
period. Actual results could differ from those estimates.

RESEARCH AND DEVELOPMENT COSTS  All research and development costs and related
special purpose equipment costs are charged to expense as incurred.

REVENUES UNDER COLLABORATIVE AGREEMENTS  Revenues under collaborative
agreements, which have been the primary source of revenues for the Company,
consist of three types of revenues. The first type, milestone payments, is
earned in connection with research activities performed under the terms of
research and development license agreements. Revenue is recognized on the
achievement of certain milestones, some of which relate to obtaining regulatory
approvals. Accordingly, the estimated dates of the milestone achievements are
subject to revision based on periodic evaluations by the Company and its
partners of the attainment of specified milestones, including the status of the
regulatory approval process. Advance payments received in excess of amounts
earned are classified as deferred contract revenues and the resulting revenues
are recognized based on work performed at a predetermined rate or level of
expense reimbursement.

Additionally, under the original Mallinckrodt agreement (see note 3),
Mallinckrodt agreed to pay a bonus to MBI equivalent to Mallinckrodt's first
year product sales of ALBUNEX at its sales price to end users of the product.
This is the second type of revenues included under the caption "Revenues Under
Collaborative Agreements." MBI recorded this bonus each quarter based upon
Mallinckrodt's sales to its customers. Finally, under the terms of the amended
distribution agreement entered into in September 1995, Mallinckrodt will pay the
Company $20.0 million over four years to further the development of FS069 (the
Company's second-generation product) and related products. These payments will
be made in 16 quarterly installments starting at $1.0 million for the first four
quarters, $1.25 million for the following eight quarters and $1.5 million for
the final four quarters. Pursuant to the agreement, half of each payment is
designated for clinical development expenses and will be recorded as deferred
revenue until such expenses are incurred, and the remaining half of each payment
will be recognized as research revenue when received.

REVENUE RECOGNITION FOR PRODUCT SOLD  The Company recognizes revenue when goods
are shipped to the customers.

REVENUE RECOGNITION FOR LICENSE FEES  The Company recognizes revenue when
license fees are received, provided the Company has no future obligations.

MBI  FINANCIAL REVIEW


INCOME TAXES  The Company accounts for income taxes in accordance with Statement
of Financial Accounting Standards No. 109 (SFAS No. 109), "Accounting for Income
Taxes." SFAS No. 109 is an asset and liability approach that requires the
recognition of deferred assets and liabilities for the expected future tax
consequences of events that have been recognized differently in the Company's
financial statements or tax returns.

CASH EQUIVALENTS  Cash equivalents include marketable securities with original
maturities of three months or less when acquired. The Company has not realized
any losses on its cash equivalents.

MARKETABLE SECURITIES  In April 1994, the Company adopted Statement of Financial
Accounting Standards ("SFAS") No. 115, "Accounting for Certain Investments in
Debt and Equity Securities." The Company's management has classified 
its investment securities as available-for-sale and records holding gains or
losses as a separate component of stockholders' equity. The cumulative effect of
the change was not material to the Company's financial statements.

CONCENTRATION OF CREDIT RISK  The Company invests its excess cash in debt
instruments of financial institutions and corporations with strong credit
ratings. The Company has established guidelines relative to diversification and
maturities that maintain safety and liquidity. These guidelines are periodically
reviewed and modified to take advantage of trends in yields and interest rates.

At March 31, 1995 substantially all of the Company's receivables were from
Mallinckrodt Medical, Inc., the Company's exclusive ALBUNEX-Registered
trademark-  distributor in the United States. 

INVENTORIES  Inventories are stated at lower of cost (first-in, first-out) or
market, and consist of the following major classes (in thousands):

                                                  ----------   ---------

Work in process and finished goods include the cost of materials, direct labor
and manufacturing overhead.

PROPERTY AND EQUIPMENT  Property and equipment are stated at cost. Depreciation
and amortization are provided using the straight-line method over estimated
useful lives of five years for equipment, 31 years for buildings and
improvements and the term of the lease for leasehold improvements. 

PATENTS AND LICENSE RIGHTS AND OTHER ASSETS  Patents and license rights are
amortized on the straight-line method over their estimated useful lives of five
to ten years.

In June 1989, the Company prepaid $2.0 million in royalties on the first $66.6
million of sales of ALBUNEX and FS069 in the United States. Included in other
assets at March 31, 1995 and 1996 is approximately $1.9 million which is the
portion of this prepayment which has not yet been expensed. Additionally, other
assets at March 31, 1995 and 1996 include $4.5 million (less amortization of
$3.9 million and $4.5 million at March 31, 1995 and 1996, respectively) paid in
connection with the Company's license for the right to make, have made, use and
sell ALBUNEX and other products using the licensed patents. Amortization was
calculated generally by using the ratio of current contract revenues earned to
total expected contract revenues related to the licensed products. These license
rights were fully amortized as of March 31, 1996.

The Company periodically reevaluates the original assumptions and rationale
utilized in the establishment of the carrying value and estimated lives of these
assets. The determinants used for this evaluation include management's estimate
of the asset's ability to generate positive income and cash flow as well as the
strategic significance of the respective assets.

                                                    ----------   ---------


LOSS PER SHARE  Loss per common share has been computed by dividing the loss by
the weighted average number of common shares outstanding during the years.
Warrants and options do not impact the per share loss since they would 
be antidilutive. 

RECENT ACCOUNTING PRONOUNCEMENTS  The Financial Accounting Standards Board
("FASB") has issued SFAS 121 "Accounting for the Impairment of Long-Lived Assets
and for Long-Lived Assets to be Disposed Of." This statement establishes
accounting standards for the impairment of long-lived assets, certain
identifiable intangibles, and goodwill related to those assets to be held and
used for long-lived assets and certain identifiable intangibles to be disposed
of. The FASB has also issued SFAS 123 "Accounting for Stock-Based Compensation."
This Statement provides companies the option to account for employee stock
compensation awards based on their estimated fair value at the date of grant,
resulting in a charge to income in the period the awards are granted, or to
present pro forma footnote disclosure describing the effect to the Company's net
income and net income per share data as if the Company had adopted SFAS 123.
SFAS 121 and SFAS 123 are effective for companies with fiscal years beginning
after December 15, 1995. The Company intends to adopt SFAS 121 and SFAS 123 in
fiscal 1997. The Company has not yet determined what impact, if any, the
adoption of SFAS 121 or SFAS 123 will have on the Company's financial statements
or related disclosures thereto.

NOTE 2. MARKETABLE SECURITIES

Investments are recorded at estimated fair market value, and consist primarily
of treasury securities, government agency securities and corporate obligations.
The Company has classified all of its investments as available-for-sale
securities. The following table summarizes available-for-sale securities at
March 31, 1995 (in thousands):

The amortized cost and estimated fair value of debt and marketable securities at
March 31, 1996, by contractual maturity, are shown below. Expected maturities
may differ from contractual maturities because the issuers of the securities may
have the right to prepay obligations without prepayment penalties.

Note 3. Significant Research Contracts

The Company conducts all of its research and development activities on its own
behalf. Under the terms of its collaborative research agreements, the Company
retains all ownership rights to its proprietary technologies, subject to
licensing arrangements made with its licensees.

In December 1987, December 1988 and March 1989, the Company entered into
respective agreements (the Original Agreements) with Nycomed A.S. (Nycomed), a
Norwegian corporation, Mallinckrodt Medical, Inc. (Mallinckrodt), of St. Louis,
Missouri and Shionogi & Co., Ltd. (Shionogi), a Japanese corporation, under
which the Company granted exclusive licenses, restricted to certain geographic
areas, to test, evaluate, develop and sell products covered by specified patents
of the Company relating directly to the design, manufacture or use of
microspheres for ultrasound imaging in vascular applications. The Company also
granted rights to sublicense, use, make and sell the licensed products under
specified royalty arrangements.

Under the terms of the Original Agreements, as amended, the Company earned and
received license fees of $6.5 million. The Original Agreements also provided for
total payments to the Company aggregating up to $66.5 million, to continue 
product development, clinical trials, preproduction and premarketing activities
relating to the Company's ultrasound imaging contrast agents for vascular
applications. These amounts were received in installments based on the
achievement of certain milestones by the Company. As of March 31, 1995, the
Company had earned revenues under the above agreements in the amount of $58.5
million of which $3.5 million had not been paid as of March 31, 1995 and is
included in accounts receivable as of that date. These amounts were received in
the first quarter of fiscal 1996. The Company does not anticipate earning the
remaining $8 million in milestones, all of which relate to the Shionogi
agreement (see note 6). Under the Mallinckrodt agreement, the Company was
entitled to receive additional payments in an amount equivalent to first year
product sales, up to a maximum of $30.0 million. The Company earned $345,000
through March 31, 1995 and earned an additional $412,000 through October 1995.
This bonus was paid in December 1995 and no future income will be earned under
this provision.

In September 1995, the Company entered into an amended and restated distribution
agreement, as well as a related investment agreement, with Mallinckrodt. Under
the amended distribution agreement, the geographical scope of Mallinckrodt's
exclusive right was expanded to include all of the countries of the world other
than those covered by the Company's license agreements with Shionogi and
Nycomed. Additionally, the duration of Mallinckrodt's exclusive right was also
extended from October 1999 until the later of July 1, 2003 or three years after
the date that the Company obtains approval from the United States Food and Drug
Administration ("FDA") to market FS069 for an intravenous myocardial perfusion
indication.

The agreement will provide the Company with between $33.0 million and $47.5
million in new financing (including the $13.0 million Common Stock investment
discussed below). Under the terms of the agreement, Mallinckrodt will make
guaranteed payments to the Company totaling $20.0 million over four years to
support clinical trials, related regulatory submissions and associated product
development of the licensed products, which include but are not limited to
ALBUNEX-Registered Trademark- and FS069. These payments will be made in 16
quarterly installments of $1.0 million for the first four quarters, $1.25
million for the following eight quarters and $1.5 million for the final four
quarters. The payments may be accelerated in the event that the Company's 


                                          3
                                          -
                                          4



cumulative outlays for clinical trials are in excess of the amounts received at
any point in time. However, the quarterly payments may not be postponed. As of
March 31, 1996 the first two quarterly payments had been received by the
Company.

The amended distribution agreement requires the Company to spend at least $10.0
million of the $20.0 million it receives over four years on clinical trials to
support regulatory filings with the FDA for cardiac indications of the licensed
products. The Company's expenditure of this $10.0 million will be made in
accordance with the directions of a joint steering committee which the Company
and Mallinckrodt established in order to expedite the development and regulatory
approval of FS069 by enabling the parties to share their expertise relating to
clinical trials and the regulatory approval process. The Company and
Mallinckrodt have each appointed two of the four members of the joint steering
committee.

The amended distribution agreement also provides for potential payments to the
Company of up to $14.5 million upon 
satisfaction of certain territorial and product development milestones. There
can be no assurance, however, that all or any of these milestones will be met. 

In connection with the amended distribution agreement, the Company also entered
into an investment agreement whereby the Company sold 1,118,761 unregistered
shares of its Common Stock to Mallinckrodt for $13.0 million, or a price of
$11.62 per share before related costs. Combined with the 181,818 shares of the
Company's Common Stock that Mallinckrodt acquired in December 1988. At March 31,
1996, Mallinckrodt owned approximately 9.8% of the Company's issued and
outstanding shares.

In addition, the amended distribution agreement grants the Company the option 
(at its own discretion) to repurchase all of the shares of the Company's 
Common Stock that Mallinckrodt purchased under the investment agreement for 
$45.0 million, subject to various price adjustments. This option is 
exercisable beginning the later of July 1, 2000 or the date that the Company 
obtains approval from the FDA to market FS069 for an intravenous myocardial 
perfusion indication and ending on the later of June 30, 2003 or three years 
after the date that the Company obtains approval from the FDA to market FS069 
for an intravenous myocardial perfusion. If the Company exercises this 
option, the Company may co-market ALBUNEX-Registered Trademark- , FS069 and 
related products in all of the countries covered by the amended distribution 
agreement. 

Mallinckrodt is the Company's principal strategic marketing partner for its
ALBUNEX and FS069 ultrasound contrast agents. Under the arrangements with
Mallinckrodt, Mallinckrodt has substantial control over all aspects of marketing
the Company's product in its territories.

In October 1995, the Company entered into an agreement whereby it reacquired all
rights to INFOSON (the European designation for ALBUNEX), FS069 and related
products from Nycomed, the Company's European licensee. The Company agreed to
pay Nycomed $2.7 million and 45% of any amounts in excess of $2.7 million that
the Company receives in payment for the transfer of marketing rights in the
former Nycomed territory to a third party. The Company also agreed to pay
Nycomed a royalty based on future sales, as defined in the agreement. These
license rights are recorded as a current asset at March 31, 1996 and include
costs associated with the reacquisition of these rights, of which $700,000 which
had been paid as of March 31, 1996 and $2.0 million which was paid in April 1996
under this agreement. The Company intends to resell the rights and is currently
in discussions with a potential licensee for this territory. Also included under
license rights are deferred fees of $300,000 which will be due and payable upon
the signing of an agreement with a third party for rights to this territory.

During the years ended March 31, 1994, 1995 and 1996, the Company received
contract research payments and earned revenue under the above agreements as
follows (in thousands):

MBI  FINANCIAL REVIEW


In May 1993 the Company entered into an exclusive license agreement for its
orally-administered abdominal ultrasound agent with Bracco S.p.A. of Milan,
Italy. The agreement granted Bracco exclusive marketing and distribution rights
to the product in Europe and the former Soviet Union. Under the terms of the
agreement, the Company received $2.0 million in license fees. In March 1994,
Bracco notified the Company that it desired to rescind the agreement and
demanded that the Company return the license fee (see note 6).

NOTE 4. INCOME TAXES

computing deferred income taxes in accordance with Statement of Financial
Accounting Standards No. 109, "Accounting for Income Taxes." 

The effective income tax rate on the loss before income taxes differs from the
statutory U.S. federal income tax rate as 
follows (in thousands):

million relating to the following tax loss carryforwards for income tax purposes
(in thousands):

For financial reporting purposes, a valuation allowance has been recognized to
offset the deferred tax assets related to the carryforwards. If realized,
approximately $2.0 million of the tax benefit for those items will be applied
directly to paid-in capital, related to deductible expenses reported as a
reduction of the proceeds from issuing Common Stock in connection with the
exercise of stock options.

The note payable due in 2004 bears interest at a variable rate based upon the
weighted average Eleventh District cost of funds plus 2.35 percent. The interest
rate on this note is adjusted semi-annually and was eight percent at March 31,
1995 and 1996. The note is secured by the Company's manufacturing facility and
certain of the equipment contained therein and is payable in monthly
installments of principal and interest. As of March 31, 1996, maturities of this
note in each of the next five fiscal years are: $62,000, $67,000, $73,000,

The note payable due in 2001 bears interest at the prime rate plus one percent
(9.25 percent at March 31, 1996) and is payable in monthly installments of
$100,000 plus accrued interest through April, 2001. The loan contains covenants
relating to cashflow coverage, minimum cash balances and requires a compensating
balance of $3.0 million. The loan is secured by the tangible assets of the
Company. This note replaces a previously outstanding note (note payable - due
2000) which was retired in March 1996 in conjunction with the sale of certain of
the Company's buildings and underlying land. Proceeds from the sale of the
buildings were approximately $6.5 million after deducting costs related to the
sale. Approximately $4.6 million of the proceeds from the sale was used to
retire the existing note payable. 

The note payable due in 2000 had an interest rate at the prime rate plus one
percent (10 percent at March 31, 1995) and was payable in monthly installments
of $20,800 plus accrued interest through April, 2000. In connection with this
financing, at March 31, 1995 the Company had a second line of credit with
available borrowings of up to $5.0 million. Both of these loans contained
covenants and were secured by the tangible assets of the Company. These notes
were refinanced in March 1996 in conjunction with the sale of certain of the
Company's buildings and underlying land. (See above note payable - due 2001).

The leases expire in fiscal 1997 and fiscal 2003 and contain renewal provisions
of up to ten years at the end of the lease terms. The Company is obligated to
pay real estate taxes, insurance and utilities on its portion of the leased
properties. Rental expense for the years ended March 31, 1994, 1995 and 1996 was
$485,000, $508,000 and $350,000, respectively.

In December 1992, the Company entered into a license and collaborative research
agreement with Dendritech, Inc. and its affiliate Michigan Molecular Institute.
The license agreement granted the Company the exclusive worldwide rights to use
Dendritech's patented dendrimer technology to develop and commercialize contrast
agents for use with magnetic resonance imaging, computerized tomography and
ultrasound. Under this agreement, the Company was committed to pay a license fee
of $500,000 per year for five years beginning December 1992. As of March 31,
1995, a total of $1.5 million in license fees had been paid. In September 1995
the Company and Dendritech signed a license termination agreement arising out of
the Company's decision to concentrate on its current ultrasound products. The
agreement terminated all financial and other obligations of MBI. The unamortized
license fees which the Company had previously capitalized of approximately $1.0
million were written-off in the year ended March 31, 1996 (see note 8).

The Company has entered into license agreements requiring future royalty
payments ranging from 11/4% to 3% of specified product sales relating to the
licensed technologies. Additionally, there is a minimum royalty payment due to
one licensor in each calendar year for the following amounts, $400,000 for 1997,
$500,000 for 1998 and $600,000 for each succeeding year.

In June 1994, the United State District Court for the Southern District of
California granted final approval to an agreement settling a class action
complaint against the Company, certain of its officers and all of the members of
its Board of Directors (Sherman v. Widder, et al., No. TS 92-1827-IEG (M)
alleging violations of the Securities Exchange Act of 1934 and California
securities laws. The Company agreed without admitting liability to pay $3.0
million in cash, and shares of MBI's Common Stock worth $1.5 million (172,414
shares valued as of March 31, 1995), into a settlement fund which was to be
distributed to qualifying class members. The Company's directors and officers
liability insurer contributed $800,000 of the cash payment. The expenses
associated with this settlement have been included in other expense during the
fiscal year ended

MBI FINANCIAL REVIEW

March 31, 1994. Pursuant to the settlement order, the distribution of cash and
stock was administered by counsel for the plaintiff class. Included in accrued
liabilities at March 31, 1995 is a liability of $1.5 million for the issuance of
this Common Stock. The shares were distributed to qualifying class members in
May, 1995.

In May 1993 the Company entered into an exclusive license agreement with Bracco
S.p.A. of Milan, Italy, for the distribution rights in Europe and the former
Soviet Union to the Company's proprietary oral ultrasound agent for imaging the
gastrointestinal tract. At that time Bracco paid the Company a license fee of
$2.0 million and undertook certain developmental obligations in the territory.
In March 1994, Bracco notified the Company that it desired to rescind the
agreement and demanded that the Company return the license fee. The Company
denied that Bracco was entitled to rescind the agreement or to the return of any
portion of the license fee, and notified Bracco that it had regarded Bracco's
notice of rescission as a breach of contract. In January 1995, Bracco filed a
demand for arbitration claiming return of the $2.0 million license fee, in
addition to other monetary relief. The Company filed a response denying the
material allegations of Bracco's demand, and also filed a counterdemand asking
for damages in the amount of at least $5.5 million and other monetary relief,
claiming that Bracco's purported rescission was in bad faith and resulted from
its acquisition of the exclusive licensee of a competing agent. On November 22,
1995, the arbitrator awarded Bracco $1.7 million plus statutory interest on a
legal theory not advanced by Bracco. MBI appealed the award to the Superior
Court of Los Angeles County. The court affirmed the award in a decision rendered
on March 4, 1996. The Company has appealed the award to the California Appellate
Court, and paid the judgment in March 1996 pending a final decision of the
appeal. The Company has recognized charges to operations aggregating
approximately $2.4 million to reflect the amount of the award, interest accrued
thereon and related attorneys' fees. Approximately $1.4 million of these charges
were recorded during the year ended March 31, 1996, and approximately $1.0
million was charged to operations in prior years (see note 8).

The Company is currently engaged in a dispute with its licensee for Japan,
Shionogi. Shionogi has been disappointed with ALBUNEX -Registered Trademark-
sales in Japan and has blamed "quality" problems. MBI denies the existence of
any quality problems with ALBUNEX and has charged Shionogi with failing to
market the product properly, failing to develop FS069, and failure to exploit
the licensed products throughout the territory. Negotiations aimed at an agreed
termination of the agreement with Shionogi broke off over Shionogi's monetary
demands. As of March 31, 1996, the parties had served each other with notices of
breach of the agreement. 

On April 11, 1996 Shionogi filed a demand for arbitration with the American
Arbitration Association seeking damages in excess of $37 million, representing
Shionogi's license fees paid under its license and cooperative development
agreement with the Company and additional development expenses for ALBUNEX
incurred by Shionogi, plus punitive damages. The Company believes that
Shionogi's claims are without merit, and that there is no factual or legal basis
for any liability of the Company. On April 16, 1996, the Company also filed a
demand for arbitration seeking in excess of $45 million plus punitive damages
for Shionogi's breach of its obligations under the license and cooperative
development agreement.

The results of the arbitration proceedings cannot be predicted. There can be no
assurance that the Company will be awarded all or any portion of the damages
that it is seeking. Moreover, it is possible that Shionogi could be awarded some
portion or all of the damages it is seeking. A ruling adverse to MBI in the
arbitration with respect to Shionogi's claim could have a material adverse
effect on the Company's business, financial condition and results of operations.
If Shionogi were awarded all the damages that it is seeking, the Company would
have difficulty meeting its anticipated cash requirements and may 
be required to reduce the scope of or eliminate one or more of its research and
development programs, to reduce the scope of or eliminate its manufacturing
activities, or attempt to obtain funds by entering into arrangements with
collaborative partners or others that may require the Company to relinquish
rights to certain technologies or products that the Company would not otherwise
relinquish. The Company's inability to fund its capital requirements would have
a material adverse effect on the Company's business, financial condition and
results of operations. The dispute may also have the effect of interrupting
ALBUNEX sales in Japan, although to the best of MBI's knowledge Shionogi is
continuing to sell ALBUNEX. Net sales in Japan were $264,000 for the year ended
March 31, 1996 and $688,000 for the fiscal year ended March 31, 1995. The
dispute may also delay the development of FS069 in Shionogi's territory.

While the Company believes its positions are proper and Shionogi's claims are
without merit, the ultimate resolution of this matter is uncertain at this time.
Management does not believe the resolution of this matter will have a material
adverse impact on the Company's financial position or results of operations.
Accordingly, no liability for potential loss, if any, has been provided for in
the accompanying Consolidated Financial Statements.

The Company is periodically a defendant in other legal actions incidental to its
business activities which may include challenges to its patent rights. While any
litigation has an element of uncertainty, the Company believes that the outcome
of any of these actions or all of them combined will not have a materially
adverse effect on its financial condition or results 
of operations.


NOTE 7. STOCKHOLDERS' EQUITY

In June 1989, 1990 and 1991 the Company issued warrants to Nycomed for 14,381,
9,508 and 14,524 shares, respectively, exercisable through June 1994, 1995 and

STOCK OPTIONS

1993 PLANS  In 1993 both the Board of Directors and the stockholders of the
Company approved the 1993 Stock Option Plan and the 1993 Outside Directors Stock
Option Plan (together, the 1993 Plans). The 1993 Plans were intended to replace
the Company's 1984 Incentive Stock Option Plan and the 1984 Nonstatutory Stock
Option Plan (together, the 1984 Plan), under which substantially all of the
options authorized to be granted have been granted. The 1993 Plans provide for
the grant of both qualified incentive stock options and nonstatutory stock
options to purchase Common Stock to employees (1993 Stock Option Plan) or non-
employee directors of the Company (1993 Outside Directors Stock Option Plan) at
no less than the fair value of the stock on the date of grant. Options granted
under these plans are exercisable per the terms specified in each individual
option, but not before one year (unless the option exercisability is accelerated
by the Company's Board of Directors), or later than ten years from the date of
grant. 

1984 PLAN  The Company had an Incentive Stock Option Plan and Nonstatutory Stock
Option Plan (together, the 1984 Plan) which provided for the grant of options to
purchase Common Stock to employees or non-employee directors of the Company at
no less than the fair value of the stock on the date of grant. Options granted
under the 1984 Plan were exercisable per the terms specified in each individual
option, but not before one year (unless the option exercisability is accelerated
by the Company's Board of Directors) or later than five years from the date of
grant. The 1984 Plan expired in July 1994 and there are no shares reserved for
future grants.
 
On May 11, 1995, the Board of Directors voted to offer the Company's non-
executive employees the opportunity to reprice certain stock options which were
originally granted under the 1984 Plan to the closing price on May 31, 1995. The
Board approved this repricing because it believes retaining key employees is in
the best interests of the stockholders and the Company. During the fourth
quarter of fiscal 1995, following a decline in the stock price and a
restructuring which included a twenty-five percent staff reduction, key 
employees were being contacted by other companies and agencies about 
employment opportunities elsewhere. The Board believes the repricing of the 
options was the most effective employment retention tool available.

NOTES RECEIVABLE FROM SALE OF COMMON STOCK  At March 31, 1995, the Company had
notes receivable from related parties of approximately $586,000 relating to the
exercise of options to purchase Common Stock of the Company by officers and
other employees. Of this amount, approximately $117,000 is included in accounts
and notes receivable and represents taxes payable by the individuals at the time
of these option exercises plus accrued interest thereon, as well as accrued
interest on purchase price notes. The amounts relating to the purchase price of
the Common Stock are recorded as a reduction to stockholders' equity. The loans
are secured by the Common Stock purchased, accrue interest at a rate of 6% and
are due by January 31, 1997. At March 31, 1996, the notes receivable from
related parties were approximately $370,000.

In December 1995, the Company repurchased 15,000 shares of Common Stock from an
officer who was leaving the Company. In connection with this transaction, a
portion of his outstanding loan which was secured by the Common Stock was
forgiven. The total amount forgiven, $56,000, had previously been included in
notes receivable from sale of Common Stock.

In January 1995, the Company received an approval bonus payment of approximately
$3.0 million from Mallinckrodt. Per the Distribution Agreement dated December 7,
1988, between Mallinckrodt and the Company, this payment was to be distributed
to key employees. In February 1995, the Company's Board of Directors approved
the payment of bonuses of approximately

$1.7 million to all of the Company's employees. In connection with these
bonuses, the Board of Directors also approved the forgiveness of two loans
(including accrued interest) which the Company had previously extended to its
chief executive and chief operating officers to permit them to exercise certain
stock options. The total amount forgiven on the notes was $1.3 million of which
$465,000 had previously been included in notes receivable from sale of Common
Stock and the remainder, which represented taxes payable at the time of the
option exercises plus accrued interest, was included in accounts and notes
receivable. The approval bonus of approximately $3.0 million is included in
revenues under collaborative agreements and the expense related to the payment
of the approximately $1.7 million of bonuses, as well as the forgiveness of
debt, is included in other expenses (see notes 3 and 8).

In November 1995, the Company entered into a contract for the sale of the two
buildings and underlying land that the Company purchased in December 1993. The
sale of the buildings was completed in March 1996 (see note 5). As a result,

value of the buildings by $667,000, the net amount it estimated to be received
from the sale.

We have audited the accompanying consolidated balance sheets of Molecular

1995 and 1996, and the related consolidated statements of operations, 
stockholders' equity and cash flows for each of the three years in the period 
ended March 31, 1996. These financial statements are the responsibility of 
the Company's management. Our responsibility is to express an opinion on 
these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in 
all material respects, the financial position of Molecular Biosystems, Inc.
