                              Insmed Incorporated
             Notes to Condensed Consolidated Financial Statements
                                  (Unaudited)

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been
prepared in accordance with generally accepted accounting principles and
applicable Securities and Exchange Commission regulations for interim financial
information. These financial statements do not include all of the information
and footnotes required by generally accepted accounting principles for complete
financial statements. It is presumed that users of this interim financial
information have read or have access to the audited financial statements
contained in the Company's Annual Report on Form 10-K for the year ended
December 31, 2000.  In the opinion of management, all adjustments (consisting of
normal recurring adjustments) considered necessary for fair presentation have
been included. Operating results for the interim periods presented are not
necessarily indicative of the results that may be expected for the full year.

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 reporting period.
Actual results could differ from those estimates. Certain prior period amounts
have been reclassified to conform to the June 30, 2001 presentation.

Stockholder Rights Plan

On May 16, 2001, the Company's Board of Directors approved a stockholder rights
agreement. Under the agreement each share of common stock has one right
attached.  The rights trade with the common stock unless they are separated upon
the occurrence of certain future events. The rights are exercisable only if a
person or group buys 15% or more of the Company's common stock, or announces a
tender offer for 15% or more of the outstanding common stock. Each right will
entitle a holder, other than the 15% acquirer, to buy one one-thousandth of a
share of the Company's Series A Junior Participating Preferred Stock at an
exercise price of $35, subject to adjustment.

If a person or group acquires 15% or more of the common stock of the Company,
each right would permit its holder to buy common stock of the Company having a
market value equal to two times the exercise price of the right. In addition, if
at any time after the rights become exercisable, the Company is acquired in a
merger, or if there is a sale or transfer of 50% or more of its assets or
earning power, each right would permit its holder to buy common stock of the
acquiring company having a market value equal to two times the exercise price of
the right.

                                      -6-


The rights expire on May 16, 2011. The Board of Directors may redeem the rights
before expiration, under certain circumstances, for $0.01 per right. Until the
rights become exercisable, they have no effect on earnings per share.

Recent Accounting Pronouncements

In June 2000, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards ("SFAS") No. 138, "Accounting for Certain
Derivative Instruments and Certain Hedging Activities," an amendment of SFAS No.
133, which is effective for fiscal years beginning after June 15, 2000. The
adoption of SFAS No. 133, as amended, did not have a significant effect on the
Company's consolidated financial statements.


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

The following discussion should be read in conjunction with the condensed
consolidated financial statements and notes thereto included in Part I - Item 1
of this Quarterly Report and the financial statements and notes thereto in the
Company's Annual Report on Form 10-K for the year ended December 31, 2000.

Overview

We discover and develop pharmaceutical products for the treatment of type 2
diabetes and other metabolic and endocrine disorders associated with insulin
resistance.  Insmed has two lead drug candidates -- INS-1 and SomatoKine(R). We
are actively developing these drugs to treat type 1 and type 2 diabetes and
polycystic ovary syndrome (commonly known as PCOS).

We have not been profitable and have accumulated a deficit of approximately
$121.5 million through June 30, 2001.  We expect to incur significant additional
losses for at least the next several years and until such time as we generate
sufficient revenue to offset expenses. Research and development costs relating
to product candidates will continue to increase. Manufacturing, sales and
marketing costs will increase as we prepare for the commercialization of our
products.

Results of Operations

For the three and six month periods ended June 30, 2001, we recorded a net loss
of $8.8 million and $18.9 million, respectively.  A net loss of $55.5 million
was reported for the three months ended June 30, 2000, and a net loss of $66.8
million was reported for the six months ended June 30, 2000.  The largest
component of the net loss for the period ended June 30, 2000 relates to a one-
time, non-cash charge of $54.4 million to write-off purchased research and
development resulting from the acquisition of Celtrix Pharmaceuticals, Inc.

Research and development expenses increased to $8.2 million from $4.2 million
for the three months ended June 30, 2000, and to $18.5 million from $6.7 million
for the six months ended

                                      -7-


June 30, 2000. Both increases were caused by increased disbursements for INS-1
and SomatoKine development programs. During the six months ended June 30, 2001,
we expended an aggregate of $11.1 million for external, clinical trial and
manufacturing costs related to INS-1, and $5.5 million for SomatoKine.

General and administrative expenses declined to $1.5 million for the three-month
period ended June 30, 2001 from $1.7 million for the three-month period ended
June 30, 2000, and increased to $2.6 million for the six-month period ended June
30, 2001 from $2.4 million for the six-month period ended June 30, 2000.  The
decline in expenses in the second quarter was caused primarily by a reduction in
consulting and legal costs.  The increase in expenses for the six-month period
was caused by higher investor relations, legal and insurance costs in the first
quarter.

In the first quarter of 2000, we recognized an $8.4 million non-cash charge for
stock compensation. Approximately $4.8 million of this charge was reversed in
the second quarter of 2000. The major component of this non-cash charge relates
to stock options exercised with a non-recourse note. Generally accepted
accounting principles require that compensation be recognized in the financial
statements based on the difference between the current market price of the
underlying stock and the market price utilized in the previous reporting period.
The non-recourse note to which the majority of the charge relates was repaid on
June 30, 2000.

At June 30, 2001, cash, cash equivalents and marketable securities were $16.2
million less than at December 31, 2000, as funds were expended for operations.

Liquidity and Capital Resources

At June 30, 2001, our cash and cash equivalents were approximately $66.9 million
and were invested in money market instruments and investment grade corporate
debt.  Our business strategy contemplates selling additional equity and entering
into agreements with corporate partners to fund research and development, and
provide milestone payments, license fees and equity investments to fund
operations.  We will need to raise substantial additional funds to continue
development and commercialization of our products.  There can be no assurance
that adequate funds will be available when we need them, or on favorable terms.
If at any time we are unable to obtain sufficient additional funds, we will be
required to delay, restrict or eliminate some or all of our research or
development programs, dispose of assets or technology or cease operations.

Forward Looking Statements

Statements included within this Management's Discussion and Analysis of
Financial Condition and Results of Operations, which are not historical in
nature, may constitute forward-looking statements for purposes of the safe
harbor provided by the Private Securities Litigation Reform Act of 1995.
Forward-looking statements include all statements regarding expected financial
position, results of operations, cash flows, dividends, financing plans,
business strategies, operating efficiencies or synergies, budgets, capital and
other expenditures, competitive positions, growth opportunities for existing or
proposed products or services, plans and

                                      -8-


objectives of management, demand for new pharmaceutical products, market trends
in the pharmaceutical business, inflation and various economic and business
trends. Such forward-looking statements are subject to numerous risks and
uncertainties, including risks that product candidates may fail in the clinic or
may not be successfully marketed, the Company may lack financial resources to
complete development of product candidates, competing products may be more
successful, demand for new pharmaceutical products may decrease, the
biopharmaceutical industry may experience negative market trends and other risks
detailed from time to time in the Company's filings with the Securities and
Exchange Commission. As a result of these and other risks and uncertainties,
actual results may differ materially from those described in the discussion
above.


ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We invest excess cash in investment grade, interest-bearing securities and, at
June 30, 2001, had $63.7 million invested in money market instruments and
investment grade corporate debt.  Such investments are subject to interest rate
and credit risk.  Our policy of investing in highly rated securities whose
maturities at June 30, 2001, are all less than one year minimizes such risks.
In addition, while a hypothetical decrease in market interest rates of 10% from
June 30, 2001 levels would reduce interest income, it would not result in a loss
of the principal and the decline in interest income would not be material.
