                          BONE CARE INTERNATIONAL, INC.
                     NOTES TO CONDENSED FINANCIAL STATEMENTS
                                   (Unaudited)

(1)      BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         Description of Business

         Bone Care International, Inc. ("Bone Care" or the "Company") is engaged
in discovering, developing and commercializing improved D-hormone therapies. In
June 1999, Bone Care received approval from the U.S. Food and Drug
Administration for an oral formulation of Hectorol(R), and in May 2000, Bone
Care received approval for the intravenous formulation. Hectorol(R) Injection
has not been approved for sale outside of the U.S. and Hectorol(R) Capsules are
approved for sale only in the U.S. and Canada. Hectorol(R) is a synthetic
D-hormone analog to manage secondary hyperparathyroidism in kidney dialysis
patients.

         Basis of Presentation

         The accompanying unaudited condensed financial statements have been
prepared from the books and records of Bone Care in accordance with accounting
principles generally accepted in the United States for interim financial
information and with the instructions to Form 10-Q and Article 10 of Regulation
S-X. Accordingly, they do not include all of the information and footnote
disclosures required by accounting principles generally accepted in the United
States for complete financial statements. In the opinion of management, all
adjustments (consisting of normal recurring accruals) considered necessary for a
fair presentation have been included. Interim results are not necessarily
indicative of the results that may be expected for the year. These financial
statements should be read in conjunction with the financial statements and
footnotes thereto for the year ended June 30, 2003 included in the Company's
Form 10-K as filed with the Securities and Exchange Commission.

         Revenue Recognition Policy

         Bone Care records sales and the related costs of Hectorol(R) Capsules
and Hectorol(R) Injection based on shipments to its customers reduced by the
estimated future returns and allowances. Revenue is recognized at the time of
shipment as risk of loss has transferred to the customer, delivery has occurred,
and collectibility is reasonably certain. Customers have a right to return
product if they are unable to sell it prior to the expiration date. In
accordance to Statement of Financial Accounting Standard (SFAS) No. 48, "Revenue
Recognition When Right of Return Exists", Bone Care's September 30, 2003 and
June 30, 2003 balance sheets include an accrual of $199,020 and $336,620,
respectively, for the estimated amount of future returns, based on historical
experience, related to Hectorol(R) Capsules and Hectorol(R) Injection.

         Accounts Receivable

         Accounts receivable is stated net of allowance for doubtful accounts of
$88,730 and $111,200 at September 30, 2003 and June 30, 2003, respectively.

         Inventory

         Inventory is stated at the lower of cost or market; cost is determined
by the first-in, first-out method. Inventory consists of the following:

         Property, Plant and Equipment

         Bone Care periodically evaluates the carrying value of property and
equipment in accordance with SFAS No. 144,"Accounting for the Impairment or
Disposal of Long-Lived Assets." Long-lived assets are reviewed for impairment
whenever events or changes in circumstances indicate that the carrying amount
may not be recoverable. If the expected future undiscounted cash flows are less
than the carrying amount of the asset, a loss is recognized for the differences
between the fair value and the carrying value of the asset. Property, plant and
equipment consisted of the following:

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

                                                  =============   ============

         Patent Fees

         Legal costs incurred to register patents are amortized on a straight
line basis over the life of the patent. Bone Care continuously evaluates whether
events and circumstances have occurred that indicate the remaining estimated
useful life of intangibles may warrant revision or that the remaining balance of
intangibles may not be recoverable. When factors indicate that intangibles
should be evaluated for possible impairment, Bone Care assesses recoverability
from expected future operations using undiscounted cash flows. Impairment would
be recognized in operating results if a permanent diminution in value occurred.
Impairment would be measured using fair value. Patent fees are stated net of
accumulated amortization of $1,171,324 and $1,131,952 at September 30, 2003 and
June 30, 2003, respectively.

         Stock Based Compensation

         Bone Care's stock-based compensation related to employees and
non-employee directors is recognized using the intrinsic value method in
accordance with Accounting Principles Board Opinion No. 25, "Accounting for
Stock Issued to Employees," and thus there is no compensation expense for
options granted with exercise prices equal to the fair value of Bone Care's
common stock on the date of the grant. Pro forma net loss and loss per share had
Bone Care elected to adopt the "fair-value based method" of SFAS No. 123 are as
follows:

          for market research.

(3)  NET LOSS PER SHARE

         Net loss per share is based on a weighted average number of shares of
common stock of 14,240,725 and 14,156,772 for the quarters ended September 30,
2003 and 2002, respectively. Options to purchase common stock have been excluded
from the calculation of diluted earnings per share as the impact of these
options on diluted earnings per share would be anti-dilutive. The excluded
options totaled 2,143,420 and 1,520,633 for the quarters ended September 30,
2003 and 2002, respectively.

(4)  COMPREHENSIVE INCOME (LOSS)

         Total comprehensive loss was $2,102,052 and $1,649,124 for the quarters
ended September 30, 2003 and 2002, respectively. Comprehensive loss is comprised
of net loss and changes in unrealized gains and losses on available-for-sale
securities.

OVERVIEW

         Bone Care International, Inc. (Bone Care) is engaged in discovering,
developing and commercializing improved D-hormone therapies. In June 1999, Bone
Care received approval from the U.S. Food and Drug Administration for an oral
formulation of Hectorol(R), and in May 2000, Bone Care received approval for the
intravenous formulation. Hectorol(R) Injection has not been approved for sale
outside of the U.S. and Hectorol(R) Capsules are approved for sale only in the
U.S. and Canada. Hectorol(R) is a synthetic D-hormone analog to manage secondary
hyperparathyroidism in kidney dialysis patients.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

         Our significant accounting policies are described in Note 1 to the
Notes to the Financial Statements in the Company's Form 10-K for the year ended
June 30, 2003. Those condensed financial statements have been prepared in
accordance with accounting principles generally accepted in the United States.
The preparation of these condensed financial statements requires us to make
estimates and judgments that affect the reported amounts of assets, liabilities,
revenues and expenses, and related disclosure of contingent liabilities. On an
on-going basis, we evaluate our estimates, including those related to our
provision for sales returns and allowances, allowance for doubtful accounts, and
our estimate of excess and obsolete inventory. We base our estimates on
historical experience and on various other assumptions that we believe to be
reasonable under the circumstances, the results of which form the basis of
judgments regarding the carrying values of assets and liabilities that are not
readily apparent from other sources. Actual results may differ from these
estimates under different assumptions or conditions.

Sales Returns and Allowances

         When revenue is recognized, Bone Care simultaneously records an
estimate of various costs, which reduce product sales. These costs include
estimates for product returns, chargebacks, rebates, and discounts. Estimates
are based on a variety of factors including historical return experience, rebate
and chargeback agreements, inventory levels at our wholesale customers, and
estimated sales by our wholesale customers to other third parties who have
contracts with us. Actual experience associated with any of these items may
differ materially from our estimates. Factors are reviewed that influence our
estimates and, if necessary, adjustments are made when we believe that actual
product returns, chargebacks, rebates, and discounts may differ from established
reserves.

Allowance for Doubtful Accounts

         An allowance is maintained for estimated losses resulting from the
inability of customers to make required payments. Credit terms are extended on
an uncollateralized basis primarily to wholesale drug distributors and
independent dialysis clinics throughout the U.S. Management specifically
analyzes accounts receivable, historical bad debts, customer credit-worthiness,
percentage of accounts receivable by aging category, and changes in customer
payment terms when evaluating the adequacy of the allowance for doubtful
accounts. If the financial condition of our customers were to deteriorate,
resulting in impairment in their ability to make payments, additional allowances
may be required. Our actual losses from uncollectible accounts have not been
material to-date.


                                      -9-


Excess and Obsolete Inventory

         Inventories are stated at the lower of cost or market, with cost
determined on the first-in, first-out method. In evaluating whether inventory is
stated at the lower of cost or market, management considers such factors as the
amount of inventory on hand, expiration dates, and the estimated time to sell
such inventory. As appropriate, provisions are made to reduce inventories to
their net realizable value. Cost of inventories that potentially may not sell
prior to expiration or are deemed of no commercial value have been written-off
when identified.

RESULTS OF OPERATIONS

         Three months ended September 30, 2003 compared to three months ended
September 30, 2002

         Product sales of Hectorol(R) were $8,125,042 for the quarter ended
September 30, 2003, an increase of $2,707,642, or 50.0% from the quarter ended
September 30, 2002. Sales of Hectorol(R) Injection were $7,036,059 for the
quarter ended September 30, 2003, an increase of $2,850,200 or 68.1% from the
same period in 2002. The increase was the result of higher demand due in part to
an expansion of our sales force and marketing efforts and a price increase of
approximately 20.0% effective July 1, 2003. Sales of Hectorol(R) Capsules were
$1,088,983 for the quarter ended September 30, 2003, a decrease of $142,558, or
11.6% from the same period in 2002. The reduction in demand was partially offset
by a price increase of approximately 5.0% effective July 1, 2003.

         Cost of product sales was $2,417,644 and $1,509,606 for the quarters
ended September 30, 2003 and 2002, respectively, representing approximately
30.0% and 28.0%, respectively, of net product sales. The higher cost as a
percent of sales for the quarter ended September 30, 2003 was primarily due to
manufacturing expenses incurred in the production of Hectorol(R) Capsules for
validation purposes, which inventory is not saleable and was therefore written
off in the quarter ended September 30, 2003.

         Research and development expense was $1,793,160 in the quarter ended
September 30, 2003, an increase of $116,536, or 7.0% from the same quarter in
2002. The increase in expense was primarily due to higher personnel expenses of
approximately $240,000 related to the hiring of our new Vice President of
Research and Development and additions in our regulatory group, offset by lower
consulting and research expenses of approximately $100,000 and $50,000,
respectively.

         Selling, general and administrative expense was $6,081,199 in the
quarter ended September 30, 2003, an increase of $2,004,111, or 49.2% from the
same quarter in 2002. Sales and marketing costs increased $1,206,775 primarily
as a result of the expansion of our field sales force representing approximately
$430,000, additional promotional programs for our products representing
approximately $550,000, and personnel recruitment expenses of approximately
$150,000. General and administrative expense increased $797,336 primarily due to
severance expenses for the former Vice President of Finance of approximately
$393,000, expenses associated with the recruitment, hiring and relocation of the
new Vice President of Finance of approximately $213,000 and an increase in
professional legal fees of approximately $105,000 principally related to an
increase in contractual, personnel and corporate governance activity.

LIQUIDITY AND CAPITAL RESOURCES

         We require cash to fund our operations, make capital expenditures and
for strategic investments. Our cash, cash equivalents, marketable securities and
long-term securities balance as of September 30, 2003 was $14,204,875, a
reduction of $3,398,570 from the June 30, 2003 balance. Our cash is invested in
highly liquid, interest-bearing, investment grade and government securities in
order to preserve principal.

         Cash used in operating activities was $3,453,579 for the three months
ended September 30, 2003. Cash was used to fund the net operating loss of
$2,102,052, for inventory purchases in anticipation of increased future demand
for our products and to pay for accrued liabilities, principally management
bonus compensation related to fiscal year end June 30, 2003.

         We used $99,587 in cash for the purchase of capital assets, primarily
computer and laboratory equipment. Our cash position was enhanced by $235,174
from stock option proceeds in the first quarter of fiscal 2004.

         Our cash and investments to-date have been used to fund our operations
and capital needs. We anticipate that annual expenditures for our active
pharmaceutical ingredient, contract manufacturing, research projects,
development of our current


                                      -10-


and planned products, regulatory activity, growth of our sales force, expansion
of our marketing programs and development of the infrastructures to accommodate
the planned growth and development, will increase in future years. Profits from
product sales, if any, may not be sufficient to support these activities. There
can be no assurance that we will be able to achieve profitability or positive
cash flow from operations. We anticipate that we will require additional
financing in the future to finance our anticipated growth and development
largely through equity or debt financing and/or strategic or corporate
alliances. We believe that our existing cash position as of September 30, 2003
is adequate to fund our operations at least until our second fiscal quarter of
2005. However, there can be no assurance that we will not require additional
capital prior to that time. There can be no assurance that additional equity or
debt financing or corporate collaborations will be available on terms acceptable
to us, if at all. The failure of the Company to achieve profitability or to
raise capital on acceptable terms if and when needed would have a material
adverse effect on our business, financial condition and results of operations.

         We currently have no internal manufacturing capabilities. We rely on
third party contractors to produce our active pharmaceutical ingredient and for
the subsequent manufacturing and packaging of finished injection and capsule
products. We rely on one supplier to formulate and package Hectorol(R)
Injection, one supplier to formulate Hectorol(R) Capsules and one supplier to
package Hectorol(R) Capsules. Although other suppliers, formulators and vendors
are available and could provide these goods and services to Bone Care on
comparable terms, any change in suppliers could cause a delay in manufacturing
and a possible loss of sales, which would affect operating results adversely. We
believe that our suppliers have sufficient capacities to meet the currently
expected demand for our products from existing and new customers and patients.
We believe our relationships with our suppliers are good.

         At June 30, 2003, we had state tax net operating loss carryforwards of
approximately $44,337,000 and state research and development tax credit
carryforwards of approximately $621,000, which will begin expiring in 2006 and
2011, respectively. We also had federal net operating loss carryforwards of
approximately $48,770,000 and research and development tax credit carryforwards
of approximately $2,040,000, which will begin expiring in 2011 and 2012,
respectively.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

         Our sales from inception to date have been made to U.S. customers and,
as a result, we have not had any exposure to factors such as changes in foreign
currency exchange rates or weak economic conditions in foreign markets. However,
in future periods, we expect to sell in foreign markets, including Europe and
Asia. As our sales are made in U.S. dollars, a strengthening of the U.S. dollar
at that time could make our products less competitive in foreign markets.

         As of September 30, 2003, we held $11,334,313 of short-term marketable
securities and $912,145 of long-term marketable securities. The investments have
been made for investment (as opposed to trading) purposes. Interest rate risk
with respect to our investments is not significant as all such investments are
in U.S. dollar cash equivalents and are:

     -   short-term investments, which are by their nature less sensitive to
         interest rate movements, or
     -   have maturities in excess of one year and are expected to be held to
         maturity, thereby eliminating the risks associated with interest rate
         changes.

ITEM 4.  CONTROLS AND PROCEDURES

         As of September 30, 2003, Bone Care's management, including its Chief
Executive Officer and Chief Financial Officer, have conducted an evaluation of
the effectiveness of disclosure controls and procedures, pursuant to Rule 13a-15
of the Securities Exchange Act of 1934, as amended. Based on that evaluation,
the Chief Executive Officer and Chief Financial Officer concluded that our
disclosure controls and procedures are effective in ensuring that all material
information required to be filed in this report has been made known to them in a
timely fashion.

         In connection with the evaluation by Bone Care's management, including
the Chief Executive Officer and Chief Financial Officer, of our internal control
over financial reporting, pursuant to Exchange Act Rule 13a-15(d), no changes
during the quarter ended September 30, 2003 were identified that have materially
affected, or are reasonably likely to materially affect, our internal control
over financial reporting.
