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

(1)  BASIS OF PRESENTATION

     The financial statements in this report have been prepared by Bone Care
International, Inc. without audit, pursuant to the rules of the Securities and
Exchange Commission for quarterly reports on Form 10-Q and do not include all of
the information and note disclosures required by accounting principles generally
accepted in the United States of America for annual financial statements. These
financial statements should be read in conjunction with the financial statements
and notes thereto for the year ended June 30, 2002, included in the Company's
Form 10-K as filed with the Securities and Exchange Commission on September 30,
2002.

     In the opinion of management, information included in this report reflects
all adjustments, consisting of normal, recurring adjustments, necessary for a
fair presentation of results for these interim periods.

     The results of operations for the interim period ended December 31, 2002,
are not necessarily indicative of the results to be expected for the entire
fiscal year ending June 30, 2003.


(2)  REVENUE RECOGNITION POLICY

     Bone Care records sales and the related costs of Hectorol Capsules and
Hectorol Injection based on shipments to its customers reduced by the estimated
future returns. The terms of sale for all product sales are F.O.B. shipping
point. 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 with Statement of
Financial Accounting Standard (SFAS) No. 48, "Revenue Recognition When Right of
Return Exists", Bone Care's December 31, 2002 balance sheet includes a $299,520
accrual for the estimated amount of future returns related to Hectorol Capsules
and Hectorol Injection.


(3)  INVENTORIES

     Inventories are stated at the lower of cost or market; cost is determined
principally by the first-in, first-out method. Inventories are comprised of:

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



(4)  PATENTS

     Effective October 1, 2002, the Company revised its estimated useful lives
for amortizing patents from 10 years to 17 years. This change in estimated lives
was based on the average term patents are enforceable. The impact of this change
on the quarter ended December 31, 2002 was to decrease the net loss by $13,000.


                                      -7-

(5)  NET LOSS PER SHARE

     Net loss per share is computed by dividing net loss by the weighted average
number of shares of common stock outstanding during the period. Options to
purchase common stock have been excluded from the calculations of diluted
earnings per share as the impact of these options on diluted earnings per share
would be anti-dilutive. As of December 31, 2002 and 2001, 1,468,033 and 909,483
options respectively, have been excluded as the impact would have been
anti-dilutive.


(6)  COMPREHENSIVE INCOME

     Total comprehensive loss was $4,145,680 and $1,228,285 for the three months
ended December 31, 2002 and 2001, respectively. Total comprehensive loss was
$5,794,804 and $3,332,194 for the six months ended December 31, 2002 and 2001,
respectively. Comprehensive income is comprised of operating results and
unrealized gains and losses on available-for-sale securities.


(7) NEW ACCOUNTING PRONOUNCEMENTS

     In November 2002, the Financial Accounting Standards Board ("FASB") issued
Interpretation ("FIN") No. 45, "Guarantor's Accounting and Disclosure
Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of
Others." FIN No. 45 requires that a guarantor must recognize, at the inception
of a guarantee, a liability for the fair value of the obligation that it has
undertaken in issuing a guarantee. FIN No. 45 also addresses the disclosure
requirements that a guarantor must include in its financial statements for
guarantees issued. The disclosure requirements in this interpretation are
effective for financial statements ending after December 15, 2002. The initial
recognition and measurement provisions of this interpretation are applicable on
a prospective basis to guarantees issued or modified after December 31, 2002.
Bone Care has not issued guarantees of indebtedness as of December 31, 2002.

     On December 31, 2002, the FASB issued SFAS No. 148, "Accounting for
Stock-Based Compensation-Transition and Disclosure." SFAS No. 148 amends SFAS
No. 123, "Accounting for Stock-Based Compensation" and provides alternative
methods of transition for a voluntary change to the fair value based method of
accounting for stock-based employee compensation. In addition, SFAS 148 amends
the disclosure requirements of SFAS 123 to require more prominent and more
frequent disclosures in financial statements of the effects of stock-based
compensation. The interim disclosure requirements of SFAS No. 148 are effective
for interim periods beginning after December 15, 2002. 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.

ITEM 2.  Management's Discussion and Analysis of Financial Condition and Results
         of Operations

Results of Operations

     Total revenues for the quarter ended December 31, 2002 decreased to
$3,743,013 from $3,831,997 in the quarter ended December 31, 2001. The decrease
was the result of a $709,572 decline in sales of Hectorol Capsules, offset by a
$620,588 increase in sales of Hectorol Injection. Sales of Hectorol Injection
were constrained in the quarter ended December 31, 2002 by an inventory
shortage. Bone Care cannot resume shipments of Hectorol Injection until one of
its suppliers gains FDA clearance. On December 16, 2002, the Company announced
that it is temporarily unable to fill customer orders for Hectorol Injection
because of the manufacturing issues described below. Total revenues for the six
months ended December 31, 2002 increased to $9,160,413 from $6,484,137 in the
six months ended December 31, 2001. The increase was the result of a $3,783,391
increase in sales of Hectorol Injection , offset by a $1,107,115 decline in
sales of Hectorol Capsules. Hectorol Capsule revenues were adversely impacted by
the introduction of a generic form of oral calcitriol, a vitamin D3, in 2002.
Hectorol Injection, launched in August 2000, generated revenues of $2,765,870
and $2,145,282 during the quarters ended December 31, 2002 and 2001,
respectively and $6,951,729 and $3,168,338 during the six months ended December
31, 2002 and 2001, respectively. Hectorol Capsules generated revenues of
$977,143 and $1,686,715 during the quarters ended December 31, 2002 and 2001,
respectively and $2,208,684 and $3,315,799 during the six months ended December
31, 2002 and 2001, respectively.

     Gross margins for the quarter ended December 31, 2002 were $2,283,175, or
61% of revenues, compared to $3,038,185, or 79% of revenues, in the quarter
ended December 31, 2001. Gross margins for the six months ended December 31,
2002 were $6,190,969, or 68% of revenues, compared to $5,097,419, or 79% of
revenues, in the six months ended December 31, 2001. Margins were lower as a
percentage of sales due to increased spending for quality assurance overhead and
costs associated with validating Hectorol Injection manufacturing at our
contract manufacturers. Validation costs were $455,000 for the quarter ended
December 31, 2002 and $551,000 for the six months ended December 31, 2002.

     Research and development expenses were $1,527,724 in the quarter ended
December 31, 2002, and $1,200,031 in the quarter ended December 31, 2001.
Research and development expenses were $2,976,160 in the six months ended
December 31, 2002, and $2,591,748 in the six months ended December 31, 2001.
These increases are attributable to consulting expenses related to validating
computer network systems, and internal costs to file the SNDA for 0.5mcg
Hectorol Capsules.

     Sales and marketing expenses increased $1,228,979 to $3,775,761 in the
quarter ended December 31, 2002, from $2,546,782 in the quarter ended December
31, 2001 and increased $2,004,094 to $6,800,711 in the six months ended December
31, 2002, from $4,796,617 in the six months ended December 31, 2001. These
increases are attributable to the addition of senior level positions within the
sales and marketing departments and increased market research and promotional
spending related to the peritoneal dialysis and chronic kidney disease markets.

     General and administrative expenses increased $366,402 to $1,259,696 in the
quarter ended December 31, 2002, from $893,294 in the quarter ended December 31,
2001. General and administrative expenses increased $731,794 to $2,540,022 in
the six months ended December 31, 2002, from $1,808,228 in the quarter ended
December 31, 2001. The increase was attributable to costs associated with hiring
the President and CEO and to increases in insurance premiums for property,
casualty, and liability policies.

     Interest income decreased $195,707 to $152,312 in the quarter ended
December 31, 2002, from $348,019 in the quarter ended December 31, 2001.
Interest income decreased $341,981 to $367,091 in the six months ended December
31, 2002, from $709,072 in the six months ended December 31, 2001. The decreases
were due to lower average cash and marketable security balances for the current
year, as well as a decline in yield on our investments.

Manufacturing

     Akorn, Inc., currently the sole manufacturer of Hectorol Injection,
received a warning letter from the FDA in September 2000 identifying general
deviations from the FDA's current Good Manufacturing Practices (c-GMP) regarding
manufacturing procedures, records and training. They received another letter
from the FDA in December 2001 identifying additional deviations from c-GMP
pursuant to a follow-up inspection of their facility. In response to this second
FDA letter, Akorn agreed to halt production of Hectorol Injection until such
time as these deviations could be remediated. Akorn has completed production of
the validation lots, which could ultimately be used as commercial product. If
the FDA's site inspection of Akorn determines that Akorn is in acceptable
compliance with c-GMP, the Company intends to submit a CBE-30 (changes being
effective in 30 days) with respect to the manufacture and process improvements
at Akorn.

     In addition, we have entered into a manufacturing agreement with Draxis
Pharma Inc., a subsidiary of Draxis Health Inc., to serve as an additional
manufacturer of Hectorol Injection. Draxis has completed production of the
validation lots, which could ultimately be used as commercial product. On
February 6, 2003, the Company submitted to the FDA a CBE-30 to add Draxis as an
additional manufacturing site for Hectorol Injection. If the FDA accepts our
submission for Draxis under an accelerated review process, commercial shipments
of Hectorol Injection could commence in approximately 30 days after filing.


Liquidity and Capital Resources

     Net cash used in operating activities was $2,698,044 for the six months
ended December 31, 2002 and $2,884,476 for the six months ended December 31,
2001. The cash used by operating activities was used primarily to fund marketing
and commercialization efforts for Hectorol Capsules and Hectorol Injection as
well as research and development.

     We have experienced negative cash flows from operations since our inception
and do not anticipate generating sufficient positive cash flows to fund our
operations until we achieve, if ever, significant revenues from the sale of
Hectorol Capsules and Hectorol Injection. We have expended, and expect to
continue to expend in the future, substantial funds for our:

     -  research and development programs;

     -  pre-clinical and clinical testing;

     -  regulatory processes, including completion of FDA post-approval Phase IV
        commitments for Hectorol Capsules and Hectorol Injection;

     -  manufacturing expenses; including validation costs for Hectorol IV at
        our contract manufacturers

     -  sales and marketing programs; and

     -  other operating expenses.

     Cash, cash equivalents and short- and long-term marketable securities were
$20,877,074 at December 31, 2002 and $24,180,661 at June 30, 2002. Cash and cash
equivalents are currently invested primarily in short-term investment grade
United States government, municipal and corporate debt securities.

     Bone Care's capital requirements will depend on numerous factors, including
the timing of the resumption of sales of Hectorol Injection; the progress of
commercialization and marketing activities; the progress of its research and
development programs; the progress of preclinical and clinical testing; the time
and cost involved in obtaining regulatory approvals; the cost of filing,
prosecuting, defending and enforcing any patent claims and other intellectual
property rights; competing technological and market developments; changes and
developments in Bone Care's existing licensing relationships and the terms of
any new collaborative, licensing, co-promotion or distribution arrangements that
Bone Care may establish; the cost of manufacturing preclinical and clinical
products;


                                      -10-


and other factors not within our control.

         Based upon our current plans, we believe that we will have sufficient
funds to meet our operating expenses and capital requirements for at least the
next year assuming remediation and validation of Hectorol Injection
manufacturing by March 31, 2003. If Hectorol Injection manufacturing has not
resumed by this date, cost reduction initiatives will be implemented. Additional
capital to fund our operations may be sought through equity or debt offerings or
other financings. There is no assurance that such additional funds will be
available on acceptable terms, if at all. Should our plans not be consummated,
we may have to seek alternative sources of capital.

         At June 30, 2002, we had state tax net operating loss carryforwards of
approximately $38,010,000 and state research and development tax credit
carryforwards of approximately $449,000, which will begin expiring in 2006. We
also had federal net operating loss carryforwards of approximately $39,352,000
and research and development tax credit carryforwards of approximately
$1,741,000, which will begin expiring in 2011.



Critical Accounting Policies and Estimates

         Our significant accounting policies are described in Note 1 to the
Notes to the Financial Statements for the year ended June 30, 2002 included in
the Company's Form 10-K as filed with the Securities and Exchange Commission on
September 30, 2002. Those financial statements have been prepared in accordance
with accounting principles generally accepted in the United States of America.
The preparation of these 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, respectively. 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 clinics throughout the United States. 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 an impairment of






                                      -11-



their ability to make payments, additional allowances may be required.
Historically, our actual losses from uncollectible accounts have been
insignificant.

         Excess and Obsolete Inventory

         Inventories are stated at the lower of cost or market, with cost
determined at standard cost which approximates actual cost. 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. Historically, cost of
inventories that potentially may not sell prior to expiration or are deemed of
no commercial value have been written-off when identified.



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. Because our sales are made in U.S. dollars, a strengthening of the U.S.
dollar could make our products less competitive in foreign markets. At December
31, 2002, we did not hold any short- or long-term investments other than
high-grade investment securities planned to be held to maturity and, therefore,
we do not believe that short-term fluctuations of interest rates would
materially affect the value of our investments.


Item 4.  Controls and Procedures

         Within the last 90 days, the Company's management, including its chief
executive officer and chief financial officer, have conducted an evaluation of
effectiveness of disclosure controls and procedures pursuant to Rule 13a-14 of
the Securities Exchange Act of 1934. Based on that evaluation, the chief
executive officer and chief financial officer concluded that the disclosure
controls and procedures are effective in ensuring that all material information
required to be filed in this quarterly report has been made known to them in a
timely fashion. There have been no significant changes in internal controls, or
in factors that could significantly affect internal controls, subsequent to the
date the chief executive officer and chief financial officer completed their
evaluation.

                          BONE CARE INTERNATIONAL, INC.


Item 1.  Legal Proceedings

               Bone Care may be a defendant from time to time in actions arising
         out of our ordinary course of business operations. In the opinion of
         management, the outcome of pending claims is not likely to have a
         material adverse effect on our financial statements.


Item 2.  Changes in Securities and Use of Proceeds

                  or other employees who have a significant role in the

     any corrective actions with regard to significant deficiencies and
     material weaknesses.
