                                   (unaudited)

NOTE 1 - Basis of Presentation

         The condensed consolidated financial statements at June 30, 1999 and
December 31, 1998 and for the three and six months ended June 30, 1999 and 1998
are unaudited, but include all adjustments which the Company considers necessary
for a fair presentation of the financial position at such dates and the
operating results and cash flows for those periods. These condensed consolidated
financial statements should be read in conjunction with the Company's audited
consolidated financial statements for the year ended December 31, 1998, which
were included as part of the Company's Form 10-K, filed with the Securities and
Exchange Commission. Results for interim periods are not necessarily indicative
of results for the entire year.

         Certain amounts in the condensed consolidated financial statements for
the three and six month periods ended June 30, 1998 have been reclassified in
order to conform to the 1999 presentation.

NOTE 2 - Inventories

         Inventories at June 30, 1999 and December 31, 1998 consisted of (in
millions):

NOTE 3 - Stock Split

         On April 6, 1999 the Company announced a two-for-one common stock split
to be distributed in the form of a 100% stock dividend (the "Stock Split"). As a
result of this action, on April 23, 1999, 23,006,816 shares were distributed to
the shareholders of record on April 16, 1999, of which 92,294 shares represented
treasury stock of the Company. The shares issued, outstanding and in treasury of
11,424,179, 11,378,032 and 46,147 at December 31, 1998 have been restated to
22,848,358, 22,756,064, and 92,294 to reflect the Stock Split. Par value remains
at $0.0001 per share. The par value of the additional shares resulting from the
Stock Split have been reclassified from additional paid-in capital to common
stock. All historical share and per share amounts in the accompanying statements
have been restated to reflect the Stock Split.

NOTE 4 - Convertible Debt

         In May 1998, the Company issued $15.0 million of subordinated
convertible debt to a third party. The debt has a five year term and a coupon
rate of 6.9% with interest payable on a semi-annual basis. The debt contains a
conversion feature that allows the third party to convert the debt into common
shares at $20 per share. In addition, the Company can call the debt at par after
three years or after two years if certain conditions are satisfied. Debt fees
are included in other assets and are being amortized on a straight-line basis
over the five year term of the debt.

NOTE 5 - Capital Lease Obligation

         In June 1999, the Company exercised its option to acquire a 93,000
square foot building in New Jersey in which its U.S. manufacturing operations
reside. The cost of such purchase was approximately $4.6 million. The Company no
longer has a lease agreement for this facility and, therefore, the related
capital lease obligation has been retired.

NOTE 7 - Net Income Per Common Share

         Basic net income per share is computed by dividing net income by the
weighted-average common shares outstanding for the period. Diluted net income
per share is reflective of all common share equivalents. The Company has
convertible debt which converts into 750,000 shares of common stock (see Note
4). This instrument has been included in diluted earnings per share for the
three and six months ended June 30, 1999 because its effect would be dilutive;
however this instrument has not been included in diluted earnings per share for
the three and six months ended June 30, 1998 because its effect would have been
anti-dilutive in such periods. A reconciliation of weighted-average shares
outstanding and net income from basic to diluted for the three and six months
ended June 30, 1999 and 1998 is as follows:

NOTE 10 - Contingencies

         In October 1996, Michael Jarcho ("Jarcho") filed suit in the United
States District Court for the Southern District of California seeking to recover
damages and declaratory judgment for the alleged breach by the Company of
Jarcho's consulting agreement. A consulting agreement had been entered into
between the Company and Jarcho on December 2, 1988. The agreement contains
certain royalty provisions for products that result from Jarcho's consultancy.
Jarcho contends, inaccurately in the Company's view, that Hylaform(R) resulted
from his consultancy. Jarcho seeks compensatory damages of $0.3 million plus a
royalty on the Company's past and future net sales of Hylaform as well as
punitive damages and recovery of attorneys fees. The Company believes that no
royalties are owed Jarcho as a result of Hylaform sales. Jarcho's case was
dismissed on January 10, 1997, on the grounds that the agreement requires such
disputes to be brought exclusively in New Jersey state court. Jarcho moved for a
partial reconsideration of the decision, the Company opposed that request, and
the request was denied. On June 16, 1997 Jarcho filed suit in New Jersey state
court. The Company intends to defend this matter vigorously. In accordance with
the Company's policy on contingencies, a liability has been recorded in the
accompanying condensed consolidated financial statements for estimated legal
fees expected to be incurred in defending the matter vigorously. The Company has
not made any provisions for any liability that might result from the claims made
by Jarcho.

                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Overview

         Biomatrix, Inc., together with its subsidiaries Biomatrix Medical
Canada Inc. ("BMC"), Biomatrix Svenska AB ("Biomatrix Svenska"), Biomatrix
(U.K.) Limited ("Biomatrix UK"), Biomatrix Limited ("Biomatrix Hong Kong"),
Biomatrix France SARL ("Biomatrix France"), Biomatrix Switzerland GmbH
("Biomatrix Switzerland"), and Biomatrix Germany GmbH ("Biomatrix Germany")
(together, "Biomatrix" or the "Company") develops, manufactures, markets and
sells a series of proprietary viscoelastic products made of biological polymers
called hylans for use in therapeutic medical applications and skin care. Hylans
are chemically modified forms of the naturally occurring hyaluronan (also known
as hyaluronic acid or sodium hyaluronate). Hylans are the second generation of
viscoelastics used in medicine, and are characterized by significantly enhanced
physical (rheological) properties (elasticity, viscosity and pseudoplasticity)
as compared to naturally occurring hyaluronan, from which the first generation
viscoelastics are made. The discovery of hylans has allowed the Company to
develop a range of patented products with superior viscoelastic properties in
the forms of fluids, gels and solids.

         The Company's business is subject to significant risks. Certain
statements contained in this Form 10-Q are forward-looking within the meaning of
Section 27A of the Securities Act of 1933 and involve risks and uncertainties,
including, but not limited to, governmental regulation, reimbursement,
dependence on distribution relationships, patents, competition, manufacturing,
rapid growth, dependence upon key personnel, fluctuation in operating results,
product liability, stock price volatility, Year 2000 matters, and other risks
detailed in the Company's reports filed under the Securities and Exchange Act,
including the Company's Form 10-K for the year ended December 31, 1998. As a
portion of the Company's future revenues may be based on payments from corporate
license and distribution agreements, the Company's total revenues and net income
will fluctuate from quarter to quarter. Some of these fluctuations may be
significant and, as a result, quarter to quarter comparisons may not be
meaningful.

Results of Operations for the three months ended June 30, 1999 and 1998

           Revenues. Total revenues for the three months ended June 30, 1999
were $25.2 million, representing an increase of $15.5 million or 160% over the
same period of the prior year. Net product sales for the three months ended June
30, 1999 were $18.1 million, representing an increase of $8.9 million or 97%
over the same period of 1998. This increase was due to greater sales of
Synvisc(R) to the Company's marketing partners in the United States, Europe and
recently launched international markets. Income from licenses, royalties and
research contracts for the three months ended June 30, 1999 and 1998 was $7.1
million and $0.5 million, respectively. The 1999 results include a
non-refundable sales-related milestone payment of $7.0 million from Wyeth-Ayerst
Laboratories while the 1998 results include a $0.4 million license fee from
Novartis Pharma AG.

           Costs and Expenses. Total costs and expenses were $11.8 million for
the three months ended June 30, 1999, representing an increase of $3.6 million
or 44% over the same period of the prior year. Cost of goods sold for the second
quarter of 1999 and 1998 were $5.2 million and $2.2 million, respectively, which
produced gross margins of 71% and 76%, respectively. This decrease in gross
margin percentage is a result of an increase in the mix of shipments from the
Company's new manufacturing facility which is operating below capacity. Research
and development expenses were $2.0 million for the second quarter of 1999,
representing a decrease of $0.5 or 20% over the second quarter of 1998. The
decrease in research and development expenses is primarily related to the fact
that 1998 included non-recurring process development costs associated with the
Company's new U.S. manufacturing facility. Selling, general and administrative
expenses for the second quarter of 1999 were $4.7 million, representing an
increase of $1.1 million or 31%, over the second quarter of 1998. This increase
is a result of higher market development costs related to Synvisc and higher
legal fees related to general corporate matters.

          OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)

Results of Operations for the six months ended June 30, 1999 and 1998

           Revenues. Total revenues for the six months ended June 30, 1999 were
$41.8 million, representing an increase of $24.6 million or 143% over the same
period of the prior year. Net product sales for the six months ended June 30,
1999 were $34.6 million, representing an increase of $20.8 million or 151% over
the same period of 1998. This increase was due to greater sales of Synvisc to
the Company's marketing partners in the United States, Europe and recently
launched international markets. Income from licenses, royalties and research
contracts for the six months ended June 30, 1999 and 1998 was $7.2 million and
$3.4 million, respectively. The 1999 results include a non-refundable
sales-related milestone payment of $7.0 million from Wyeth-Ayerst Laboratories
and the 1998 results include a $3.1 million license fee from Novartis Pharma AG.

           Costs and Expenses. Total costs and expenses were $22.8 million for
the six months ended June 30, 1999, representing an increase of $8.0 million or
54% over the same period of the prior year. Cost of goods sold for the six
months ended June 30, 1999 and 1998 were $10.1 million and $3.6 million,
respectively, which resulted in gross margins of 71% and 74%, respectively.
This decrease in gross margin percentage is a result of an increase in the mix
of shipments from the Company's new manufacturing facility which is operating
below capacity. Research and development expenses were $4.2 million for the
first six months of 1999, representing a decrease of $0.6 million or 13%
over the comparable period in 1998. The decrease in research and development
expenses is primarily related to process development costs associated with the
Company's new U.S. manufacturing facility which were incurred during 1998.
Selling, general and administrative expenses for the first six months of 1999
were $8.5 million, representing an increase of $2.1 million or 33% over the
first six months of 1998. This increase is primarily due to increased staffing
needed to support the scope of the Company's growing global activities.

Income Taxes

           The Company recorded federal and state tax provisions totaling $7.7
million and $0.9 million for the six months ended June 30, 1999 and 1998,
respectively. The consolidated effective rate for the first six months of 1999
was 41% as compared to 32% for the first six months of 1998. The effective rate
in 1998 was lower due to the utilization of net operating loss carryforwards.
The Company expects its consolidated effective tax rate in 1999 to continue to
approximate the combined statutory federal and state rate. The effective rate
could potentially exceed the combined statutory federal and state rate in the
future depending on the amount of certain non-deductible foreign losses.

         As of June 30, 1999 the Company had $2.8 million of net deferred U.S.
tax assets included in other long term assets on its balance sheet, as it is
more likely than not that the Company will realize the benefit of these assets.
The Company has provided a full valuation allowance on certain foreign-related
deferred tax assets due to their uncertainty of realization.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
          OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)

Liquidity and Capital Resources

         The Company had cash and cash equivalents of $21.3 million at June 30,
1999. Overall, the Company's cash position increased by $4.8 million during the
six months ended June 30, 1999.

         The Company's operations and capital growth over the past several years
have been financed by up-front non-refundable license fee payments from
corporate partners, the utilization of the Company's cash and investments and
the private placement of debt and equity securities. Since January 1, 1996, the
Company has received funding of $39.4 million from non-refundable license fee
payments and $21.0 million from the private placement of equity and debt
securities.

           For the six months ended June 30, 1999 the Company had positive cash
flows from operations of $16.2 million resulting principally from operating
income and an increase in accrued expenses. During the six months ended
June 30, 1999, the Company invested $7.2 million in property, plant, and
equipment, primarily associated with the construction of certain research and
development laboratories. In June 1999, the Company exercised its option to
acquire a 93,000 square foot building in New Jersey in which its U.S.
manufacturing operations reside. The cost of such purchase was approximately $
4.6 million. The Company no longer has a lease agreement for this facility and,
therefore, the related capital lease obligation has been retired.

         Subsequent to June 30, 1999, the Company received payment of $7.0
million from Wyeth-Ayerst Laboratories. Such payment was for the sales-related
milestone which was recorded during the second quarter of 1999.

YEAR 2000

         The Year 2000 issue is the result of computer programs being written
using two digits rather than four digits to define the applicable year. Some
computer 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 system
failure or miscalculations causing disruptions of operations, including a
temporary inability to process transactions, send invoices, or engage in normal
business and operating activities.

         Most of the Company's systems are Year 2000 compliant. The Company has
a program in place to assess the remaining software and systems and bring them
into Year 2000 compliance in time to minimize any significant detrimental
effects on operations. The program focuses on three main functional areas:

         i) Information technology which addresses data, phone and
         administrative systems, including personal computers,
         telecommunications, local area networks, wide area networks and
         business applications. These systems are computer devices and software
         that the company wrote or purchased which are not supported by external
         vendors. The software systems include applications developed or
         purchased by corporate departments and operated by departmental
         personnel. The computer devices are desktop personal computers and
         server computer equipment including system hardware, firmware, and
         installed commercial application software.

         ii) Embedded chip technology which addresses manufacturing systems,
         laboratory instruments and plant maintenance systems with programmable
         logic controllers with date functions. The Process Control and
         Environmental Monitoring and Control Systems are used in the Company's
         manufacturing and research and development processes, among other
         operations. These generally are systems, devices and instruments which
         utilize date functionality and generate, send, receive or manipulate
         date-stamped data and signals. These systems may be found in data
         acquisition/processing software, laboratory instrumentation, and other
         equipment with embedded code.

          OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)

Year 2000 (continued)

         iii) Material suppliers and marketing partners which address third
         parties that are critical to the Company's manufacturing process and
         distribution of product. The Company has identified critical providers
         of information, goods and services in order to assess their Year 2000
         compliance/readiness. The Company has sent letters to all critical and
         regular suppliers and marketing partners. The Company has received
         approximately 75% of all critical responses. Although the Company
         cannot control the response time to its letters, it hopes to have
         assessed all responses by September 30, 1999. The Company recognizes
         that to a certain degree it is relying on information provided by such
         third parties regarding their Year 2000 compliance readiness. While the
         Company is attempting to evaluate information provided by these third
         parties, there can be no assurance that in all instances accurate
         information is being provided. Failure of these third parties' systems
         to be Year 2000 compliant could have a material adverse effect on the
         Company's financial position, results of operations and cash flows.

         In order to address the three noted areas, the Company has divided the
project into four phases including awareness, assessment, validation, and
implementation along the functional departments of the Company. The Company has
completed the awareness, assessment and validation phases for all functional
areas. Full implementation and compliance for all functional areas is expected
by September 30, 1999.

         The Company is using both internal and external resources to identify,
correct/reprogram, and test its computer systems, equipment and software for
Year 2000 compliance.

         The Company estimates that the costs associated with its internal
preparation for the Year 2000 issue will not be material, and as such will not
have a significant impact on the Company's financial position or operating
results. However, the failure to correct a material Year 2000 problem could
result in an interruption in certain normal business activities or operations.
Such failures could materially and adversely affect the Company's results of
operations, liquidity and financial condition. The Company believes that, with
the implementation of the Year 2000 program, the possibility of significant
interruptions of normal operations will be reduced. To date the Company
estimates that it has spent approximately $0.2 million replacing, upgrading, or
repairing systems or equipment. The aggregate additional costs of the Company's
Year 2000 program cannot be known at this time. However, given the current
status of the project the additional internal preparation costs are expected to
be approximately $0.5 million. The actual additional costs will depend on
numerous factors, including without limitation, the costs of replacing,
upgrading or repairing systems, software and equipment, and consulting fees and
expenses. All costs are expected to be funded through operations.

         The Company is also developing a contingency plan to address a
situation in which Year 2000 problems do cause an interruption in normal
business activities. Once developed, contingency plans and related cost
estimates will be continually refined, as additional information becomes
available. The Company expects to have the contingency plan in place for
critical operations by September 30, 1999.

         There can be no assurance that the Company will be able to complete all
of the modifications in the required time frame, that unanticipated events will
not occur or that the Company will be able to identify all Year 2000 issues
before problems arise. Therefore, there can be no assurance that the Year 2000
issue will not a have a material adverse effect on the Company's financial
position, results of operations and cash flows.

         The statements set forth herein concerning the Year 2000 problem which
are not historical facts are forward-looking statements that involve risk and
uncertainties that could cause actual results to differ materially from those in
the forward-looking statements. There can be no guarantee that any estimates or
other forward-looking statements will be achieved and actual results could
differ significantly from those planned or contemplated. The Company plans to
update the status of its Year 2000 program as necessary in its periodic filings
and in accordance with applicable securities laws.
