                                 Unaudited

1. BASIS OF PRESENTATION.

The accompanying unaudited condensed consolidated financial statements for
the three months ended June 30, 2000 include the accounts of Leiner Health
Products Inc. (the "Company") and its subsidiaries, including Vita Health
Products Inc. ("Vita Health"). Such financial statements have been prepared
in accordance with generally accepted accounting principles 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 footnotes required by generally accepted accounting principles for
complete financial statements. In the opinion of management, all adjustments
(consisting of normal recurring accruals and adjustments recorded in
connection with the acquisition of assets accounted for under the purchase
method - Note 2) considered necessary for a fair presentation have been
included. Operating results for the three month period ended June 30, 2000
are not necessarily indicative of the results that may be expected for the
year ended March 31, 2001.

The balance sheet at June 30, 2000 has been derived from the audited
financial statements at that date but does not include all of the information
and footnotes required by generally accepted accounting principles for
complete financial statements. For further information, refer to the
consolidated financial statements and footnotes thereto included in the
Company's Annual Report on Form 10-K for the year ended March 31, 2000.
Certain reclassifications have been made to the fiscal 2000 condensed
consolidated financial statements to conform with the fiscal 2001
presentation.

2. ACQUISITION

On December 17, 1999, Leiner Health Products Inc. acquired substantially all
of the assets of Granutec, Inc. ("Granutec"), a manufacturer and distributor
of private label, over-the-counter pharmaceutical drugs ("OTC's") in the
United States, and Vita Health acquired substantially all of the assets of
Stanley Pharmaceuticals Ltd. ("Stanley"), a manufacturer and distributor of
private label, OTC's and vitamin supplement products in Canada, both of which
were subsidiaries of Novopharm Limited of Ontario, Canada ("Novopharm"). The
Company also acquired certain related assets of Novopharm (collectively, the
"Acquisition"). On June 29, 2000, the Company reached a final settlement
agreement with Novopharm on the working capital adjustment provided for in
the acquisition agreement and, as a result, Novopharm will pay the Company
$1,553,000. The Company will record adjustments to the asset allocation
resulting from the settlement in the second quarter of fiscal year 2001.

In connection with the Acquisition, the Company has recorded approximately
$7,015,000 for accrued restructuring charges. The restructuring plan includes
initiatives to integrate the operations of the Company with those of Granutec
and Stanley, and reduce overhead, primarily through the transfer of certain
manufacturing activities to lower cost facilities. The Company expects these
actions to result in a reduction in workforce. Management is in the process
of finalizing its restructuring plans and, accordingly, the amounts recorded
are based on management's current estimate of those costs. The Company will
finalize these plans during fiscal year 2001, and expects the majority of the
restructuring actions to occur in fiscal year 2001 and 2002.

Certain components of the restructuring plan are based on preliminary estimates
that are still being finalized. While the ultimate resolution of these matters
may result in adjustments to the purchase price allocation, management believes
that such amounts will not be materially different from those previously
recorded.

4. LONG-TERM DEBT

The Company and certain financial institutions have entered into an Amended
and Restated Credit Agreement (the "Credit Agreement" and together with the
subsequent amendments thereto, the "Amended Credit Agreement").

                                 (continued)

4. LONG-TERM DEBT (CONTINUED)

The Amended Credit Agreement provides for one U.S. term loan due December 30,
2004 in the amount of $68,000,000, two U.S. term loans due December 30, 2005
in the amounts of $65,000,000 and $30,000,000, respectively, a Canadian
dollar denominated term loan due December 30, 2004 in the amount of
approximately U.S. $12,000,000 (collectively, the "Term Facility"), and a
revolving credit facility in the amount of U.S. $125,000,000 (the "Revolving
Facility") a portion of which is made available to Vita Health in Canadian
dollars. The unpaid principal amount outstanding on the Revolving Facility is
due and payable on June 30, 2003.

Borrowings under the Amended Credit Agreement bear interest at floating rates
that are based on the lender's base rate (9.50% at June 30, 2000), the
lender's Canadian prime rate (7.50% at June 30, 2000), LIBOR (6.78% at June
30, 2000) or the lender's banker's acceptance rate (5.89% at June 30, 2000),
as the case may be, plus an applicable margin, that is itself based on the
Company's leverage ratio (as defined in the Amended Credit Agreement). The
leverage ratio is defined generally as the ratio of total funded indebtedness
to the consolidated earnings before interest, taxes, depreciation,
amortization expense and other special charges and its effect on the
applicable margin varies as follows: (a) for U.S. and Canadian revolving
credit borrowings, from 1.0% to 2.5% for LIBOR- or banker's acceptance-based
loans, and from zero to 1.5% for alternate base rate- or Canadian prime
rate-based loans, (b) for the loans under the Term Facility, from 2.625% to
3.25% for LIBOR-based loans, and from 1.625% to 2.25% for alternate base rate
loans. As of June 30, 2000, the Company's weighted average interest rates
were 9.10% for U.S. borrowings and 8.47% for Canadian borrowings. In addition
to certain agent and up-front fees, the Amended Credit Agreement requires a
commitment fee of up to 0.5% of the average daily unused portion of the
revolving facility based on the Company's leverage ratio.

In order to manage its interest rate risk under the Amended Credit Agreement,
the Company entered into two interest protection agreements. On July 30,
1997, the Company entered into an interest protection arrangement covering
$29,460,000 of its borrowings under the Amended Credit Agreement. Under this
arrangement, the Company obtained a fixed interest rate of 6.17% on LIBOR,
instead of the fluctuating rate as described above. This agreement expired on
July 30, 2000. On October 8, 1999, the Company entered into an interest
protection agreement with respect to $54,000,000 of its indebtedness under
the Amended Credit Agreement, whereby the Company will not pay any lower than
5.94% on LIBOR rates plus applicable margin on the interest payable thereon.
In connection with this agreement, which terminates October 8, 2001, the
Company received $229,500 that is being recorded as a reduction of interest
expense over the period of the agreement.

The Amended Credit Agreement contains financial covenants that require, among
other things, the Company to comply with certain financial ratios and tests,
including those that relate to the maintenance of specified levels of cash
flow and shareholder's equity. The Company was in compliance with all such
financial covenants as of June 30, 2000. As of June 30, 2000, the Company had
$37,864,000 available under its Revolving Facility.

6.  RELATED PARTY TRANSACTIONS

On June 30, 1997, Leiner Health Products Group Inc. ("Leiner Group"), the
Company's sole shareholder, and the Company entered into a consulting
agreement with North Castle Partners, L.L.C. (the "Sponsor") to provide the
Company with certain business, financial and managerial advisory services.
Mr. Charles F. Baird, Jr., Chairman of Leiner Group's Board of Directors,
acts as the managing member of the Sponsor through Baird Investment Group,
L.L.C. ("Baird Investment"). In exchange for such services, Leiner Group and
the Company have agreed to pay the Sponsor an annual fee of $1,500,000,
payable semi-annually in advance, plus the Sponsor's reasonable out-of-pocket
expenses. This fee may be reduced upon completion of an initial public
offering of Leiner Group's shares. The agreement terminates on June 30, 2007,
unless Baird Investment ceases to be the managing member of North Castle
Partners I, L.L.C. ("North Castle"), or upon the earliest of June 30, 2007 or
the date that North Castle terminates the agreement.

7.  CONTINGENCIES

On September 27, 1999, the Company filed a civil antitrust lawsuit (the
"Antitrust Lawsuit") against certain of its raw material suppliers and other
alleged co-conspirators. The complaint alleges that the defendants conspired
to fix vitamin prices and allocate vitamin production volume and vitamin
customers in the United States. The complaint seeks

unspecified damages and injunctive relief. After the lawsuit was filed, it
was consolidated, for pre-trial purposes with other similar cases. Based on
the pretrial schedule set forth by the court, the case will not be ready for
trial until approximately April 2002. At the present time, management cannot
predict the outcome of this lawsuit, nor the estimated damages and potential
recovery, if any.

In June 2000, the Company entered into a settlement agreement with one of its
suppliers named in the Antitrust Lawsuit (the "Settlement Agreement").
Pursuant to the terms of the Settlement Agreement, the Company agreed to
release all claims it may have against the supplier based on the Company's
purchases of various vitamins from the supplier and to opt out of any
settlement in connection with a pending class action lawsuit in so far as it
pertains to the supplier.

In exchange for the Company's release and agreement to opt out of any
settlement in the pending class action lawsuit, the Company received a
settlement payment on June 30, 2000 of approximately $16,734,000, net of
legal fees of approximately $188,000, which is recorded in other operating
(income) charges in the accompanying Statement of Operations for the quarter
ended June 30, 2000. In addition, the Company incurred approximately
$1,680,000 of consulting expenses paid in connection with the lawsuit and a
bonus payment of $1,150,000 awarded to certain of the Company's key
management personnel in recognition of the effect of antitrust activity on
prior years' compensation.

The Company is subject to other legal proceedings and claims which arise in
the normal course of business. While the outcome of these proceedings and
claims cannot be predicted with certainty, management does not believe the
outcome of any of these matters will have a material adverse effect on the
Company's consolidated financial position, results of operations or cash
flows.

8.  BUSINESS SEGMENT INFORMATION

The Company operated in two reportable segments. One represents the Company's
U.S. operations, including Granutec ("Leiner U.S.") and the other represents
the Company's Canadian operations, including Stanley ("Vita Health"). The
Company's operating segments manufacture a range of vitamins, minerals and
nutritional supplements and OTC's and distribute their products primarily
through mass market retailers. The Company evaluates segment performance
based on operating profit, before the effect of non-recurring charges and
gains, and inter-segment profit.

Selected financial information for the Company's reportable segments for the
three months ended June 30, 2000 and 1999 is as follows (in thousands):

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


OVERVIEW

The following discussion explains material changes in the consolidated
results of operations for Leiner Health Products Inc. and its subsidiaries
(the "Company") including Vita Health Products Inc. of Canada ("Vita
Health"), a wholly-owned subsidiary, for the three months ended June 30, 2000
("first quarter of fiscal 2001") and the significant developments affecting
its financial condition since March 31, 2000. The operating results of the
acquired operations for Granutec, Inc. ("Granutec") and Stanley
Pharmaceuticals Ltd. ("Stanley") are included in the Company's financial
statements. The following discussion should be read in conjunction with the
Company's audited consolidated financial statements and notes thereto for the
year ended March 31, 2000, which are included in the Company's Annual Report
on Form 10-K, on file with the Securities Exchange Commission.

ACQUISITION

On December 17, 1999, Leiner Health Products Inc. acquired substantially all
of the assets of Granutec, Inc. ("Granutec"), a manufacturer and distributor
of private label, over-the-counter pharmaceutical drugs ("OTC's") in the
United States, and Vita Health acquired substantially all of the assets of
Stanley Pharmaceuticals Ltd. ("Stanley"), a manufacturer and distributor of
private label, OTC's and vitamin supplement products in Canada, both of which
were subsidiaries of Novopharm Limited of Ontario, Canada ("Novopharm"). The
Company also acquired certain related assets of Novopharm (collectively, the
"Acquisition"). On June 29, 2000, the Company reached a final settlement
agreement with Novopharm on the working capital adjustment provided for in
the acquisition and, as a result, Novopharm will pay the Company $1.6
million. The Company will record adjustments to the asset allocation
resulting from the settlement in the second quarter of fiscal year 2001.

In connection with the Acquisition, the Company has recorded approximately
$7.0 million for accrued restructuring charges. The restructuring plan
includes initiatives to integrate the operations of the Company with those of
Granutec and Stanley, and reduce overhead, primarily through the transfer of
certain manufacturing activities to lower cost facilities. The Company
expects these actions to result in a reduction in workforce. Management is in
the process of finalizing its restructuring plans, and, accordingly, the
amounts recorded are based on management's current estimate of those costs.
The Company will finalize these plans during fiscal year 2001, and expects
the majority of the restructuring actions to occur in fiscal year 2001 and
2002.

Certain components of the restructuring plan are based on preliminary estimates
that are still being finalized. While the ultimate resolution of these matters
may result in adjustments to the purchase price allocation, management believes
that such amounts will not be materially different from those previously
recorded.

                                   (continued)

SEASONALITY

The Company's business is seasonal, as increased vitamin usage corresponds with
the cough, cold and flu season. Accordingly, the Company historically has
realized a significant portion of its sales, and a more significant portion of
its operating income, in the second half of its fiscal year.

The following table summarizes the Company's historical results of operations as
a percentage of net sales for the three months ended June 30, 2000 and 1999.

Net sales for the first quarter of fiscal 2001 were $130.1 million, an increase
of $9.2 million, or 7.6% versus the first quarter of fiscal 2000. This increase
was due to the Acquisition, which provided an additional $30.6 million primarily
from sales of OTC's. Excluding sales generated by Granutec and Stanley, net
sales decreased $21.4 million compared to the prior year. The decrease in net
sales excluding Granutec and Stanley was primarily in the vitamin category. This
reflects a general slowdown in the overall U.S. vitamin market for food, drug
and mass merchandisers ("FDM Market") in the first quarter of fiscal 2001 versus
the comparable period in fiscal year 2000. Management estimates that the FDM
Market declined approximately 7.7% in the 13 week period ended June 25, 2000
versus the comparable period in 1999 which had grown by approximately 9.0%.
Management plans to focus on the development of new product programs to attract
consumers from specialty retail channels to existing customer stores.

Gross profit for the first quarter of fiscal 2001 was $25.5 million, a decrease
of $4.7 million, or 15.8%, from $30.2 million in the first quarter of fiscal
2000. Gross profit margin was 19.6% for the first quarter of fiscal 2001, down
from 25.0% in the first quarter of the prior fiscal year. The increase in sales
volume generated as a result of the Acquisition provided additional gross profit
of $5.7 million, which was offset by the gross profit reduction of $7.2 million
from decreased sales, primarily vitamin sales, in the Company's other
operations. Additional regulatory and internal quality requirements for the
production and packaging of pharmaceutical drug products versus vitamin
products, generated lower gross profit margin in the three months ended June 30,
2000 versus the three months ended June 30, 1999. The significant shift in

                                   OPERATIONS
                                   (continued)

the Company's product mix from the first quarter of fiscal year 2000 to
the first quarter of fiscal year 2001, due to the Acquisition and the
continuing slowdown in the vitamin market, was the primary reason for the
decrease in the gross profit margin.

Marketing, selling and distribution expenses, together with general and
administrative expenses, and research and development expenses (collectively,
"Operating Expenses") increased by $1.9 million, or 6.7% for the first
quarter of fiscal 2001 as compared to the comparable period in fiscal 2000.
Excluding Operating Expenses for Granutec and Stanley, Operating Expenses for
the Company were $27.3 million for the first quarter of fiscal 2001,
representing a decrease of $1.1 million or 3.8% over the first quarter of
fiscal 2000. Operating Expenses for Granutec and Stanley were $3.0 million
during the first quarter of fiscal year 2001. As a percentage of net sales,
Operating Expenses were 23.3% during the three months ended June 30, 2000,
slightly lower than 23.5% during the comparable period in fiscal year 2000.
The decrease in Operating Expenses as a percentage of net sales was the
result of lower fixed spending on consultants and advertising.

Amortization of goodwill and other intangibles increased by $1.0 million in
the first quarter of fiscal year 2001 versus the first quarter of fiscal year
2000, primarily as a result of the Acquisition.

During the first quarter of fiscal 2001, the Company recorded $13.4 million
of other income compared to other charges of $0.4 million in the three months
ended June 30, 1999. This change was primarily attributable to other income
generated by a settlement arising from a supplier dispute in the amount of
$16.7 million, which is net of legal fees of approximately $0.2 million. In
connection with this settlement, the Company incurred approximately $1.7
million of consulting expenses, and awarded a bonus of approximately $1.1
million to certain of the Company's key management personnel in recognition
of the effect of antitrust activity on prior years' compensation. Other
operating (income) charges also includes management fees of $0.4 million and
other operating charges of $0.1 million.

In the first quarter of fiscal 2001, net interest expense of $8.8 million
represents an increase of $1.6 million from the first quarter of fiscal 2000.
This increase in the three months ended June 30, 2000 was due primarily to an
increase in the average outstanding indebtedness of the Company due to the
Acquisition and, to a lesser degree, an increase in interest borrowing rates.

The benefit for income taxes for the first quarter of fiscal 2001 was $0.8
million, compared to a $3.0 million benefit in the first quarter of fiscal
2000. Based on the latest estimates, the Company expects its effective tax
rate to be approximately 52% for the remainder of fiscal 2001, and to be
higher than the combined federal and state rate of 40% primarily because of
the nondeductibility for income tax purposes of goodwill amortization.

Primarily as a result of the factors discussed above, a net loss of $1.0
million was recorded in the first quarter of fiscal 2001 compared to a net
loss of $4.1 million in the first quarter of fiscal 2000.

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

OTHER INFORMATION

Earnings before interest, taxes, depreciation, amortization, other non-cash
charges and the charges related to the closure of facilities ("EBITDA")
totaled $13.7 million for the first quarter of fiscal 2001, compared to $4.8
million in the comparable period in fiscal 2000. EBITDA can be calculated
from the financial statements with the exception of the amortization of
deferred debt issuance costs totaling $0.5 million and $0.4 million for the
three months ended June 30, 2000 and 1999, respectively, which is included in
interest expense in the statement of operations and in amortization expense
in the statement of cash flows. The Company believes that EBITDA provides
useful information regarding the Company's debt service ability, but should
not be considered in isolation or as a substitute for the statements of
operations or cash flow data.

LIQUIDITY AND CAPITAL RESOURCES

The Company's cash has historically been used to fund capital expenditures,
working capital requirements and debt service. The Company is required to
repay the $170.4 million in term loans outstanding as of June 30, 2000 under
the Amended Credit Agreement (defined below) by December 30, 2005 with
scheduled principal payments of $1.3 million for fiscal 2001, $1.7 million
for fiscal 2002 and 2003, $37.0 million for fiscal 2004, $82.3 million for
fiscal 2005, and $46.4 million for fiscal 2006. The Company is also required
to apply certain asset sale proceeds, as well 50% of its excess cash flow (as
defined in the Amended Credit Agreement) unless a leverage ratio test is met,
to prepay the borrowings under the Amended Credit Agreement. All outstanding
revolving credit borrowings under the Amended Credit Agreement will become
due on June 30, 2003.

During the first three months of fiscal year 2001, net cash provided by
operating activities totaled $20.3 million. This resulted primarily from a
net loss of $1.0 million combined with $7.5 million of non cash charges to
operations and changes in operating assets and liabilities totaling $13.8
million. Changes in operating assets and liabilities are comprised of
collections of accounts receivable of $57.0 million, and an increase of $2.8
million in accounts payable and other accrued expenses net of, a decrease in
the bank checks outstanding of $11.6 million, and an increase in inventory
spending of $34.5 million. The decrease in accounts receivable and increase
inventory is due primarily to the seasonality of the Company's business
whereby sales are normally higher in the fourth quarter of the fiscal year.

During the first three months of fiscal year 2001, net cash used in investing
activities totaled $8.0 million. This was primarily due to net capital
expenditures of $4.1 million, and a $2.2 million investment in a joint
venture. The major capital expenditures related to investments in capacity
expansion at the Company's manufacturing, packaging and distribution facility
in South Carolina.

Net cash used in financing activities during the first quarter of fiscal year
2001 totaled $0.6 million, which primarily related to the payment of the
Company's long term debt.

In June 2000, the Company entered into a settlement agreement with one of its
suppliers named in the Antitrust Lawsuit. Pursuant to the terms of the
Settlement Agreement, the Company agreed to release all claims it may have
against the supplier based on the Company's purchases of various vitamins
from the supplier and to opt out of any settlement in connection with a
pending class action lawsuit in so far as it pertains to the supplier.

In exchange for the Company's release and agreement to opt out of any
settlement in the pending class action lawsuit, the Company received a
settlement payment on June 30, 2000 of approximately $16.7 million, net of
legal fees of approximately $0.2 million, which is recorded in other
operating (income) charges in the accompanying Statement of Operations and
generated a positive impact in the Company's working capital during the three
months ended June 30, 2000.

FINANCING ARRANGEMENTS

The Company and certain financial institutions have entered into an Amended
and Restated Credit Agreement (the "Credit Agreement" and together with the
subsequent amendments thereto the "Amended Credit Agreement").

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

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

The Amended Credit Agreement provides for one U.S. term loan due December 30,
2004 in the amount of $68.0 million, two U.S. term loans due December 30,
2005 in the amounts of $65.0 million and $30.0 million, respectively, a
Canadian dollar denominated term loan due December 30, 2004 in the amount of
approximately U.S. $12.0 million (collectively, the "Term Facility"), and a
revolving credit facility in the amount of U.S. $125.0 million (the
"Revolving Facility"), a portion of which is made available to Vita Health in
Canadian dollars. The unpaid principal amount outstanding on the Revolving
Facility is due and payable on June 30, 2003. As of August 8, 2000, the
Company's unused availability under the Amended Credit Agreement was
approximately $28.3 million.

Borrowings under the Amended Credit Agreement bear interest at floating rates
that are based on LIBOR or on the applicable alternate base rate (as defined
in the Amended Credit Agreement), plus applicable margins, and accordingly
the Company's financial condition and performance is and will continue to be
affected by changes in interest rates. The Company entered into an interest
protection arrangement effective July 30, 1997 with respect to $29.5 million
of its indebtedness under the Amended Credit Agreement that provides a fixed
rate of 6.17% on LIBOR. The agreement expired on July 30, 2000. On October 8,
1999, the Company entered into an interest protection agreement, with respect
to $54.0 million of its indebtedness under the Amended Credit Agreement,
whereby the Company will not pay any lower than 5.94% on LIBOR rates plus
applicable margin on the interest payable thereon. In connection with this
transaction, the Company received approximately $0.2 million that is being
recorded as a reduction of interest expense over the period of the agreement,
which terminates October 8, 2001. The Amended Credit Agreement imposes
certain restrictions on the Company, including restrictions on its ability to
incur additional debt, enter into sale-leaseback transactions, incur
contingent liabilities, pay dividends or make distributions, incur or grant
liens, sell or otherwise dispose of assets, make investments or capital
expenditures, repurchase or prepay its senior subordinated notes due 2007
(the "Notes") or other subordinated debt, or engage in certain other
activities. The Company must also comply with certain financial ratios and
tests, including a minimum net worth requirement, a maximum leverage ratio, a
minimum interest coverage ratio and a minimum cash flow coverage ratio. The
Company may be required to purchase the Notes upon a Change of Control (as
defined in the indenture) and in certain circumstances with the proceeds of
asset sales. The Notes are subordinated to the indebtedness under the Amended
Credit Agreement. The indenture governing the Notes imposes certain
restrictions on the Company and its subsidiaries, including restrictions on
its ability to incur additional debt, make dividends, distributions or
investments, sell or otherwise dispose of assets, or engage in certain other
activities.

A portion of the outstanding borrowings under the Amended Credit Agreement,
amounting to approximately U.S. $28.5 million as of June 30, 2000, is
denominated in Canadian dollars. All other outstanding borrowings under the
Amended Credit Agreement, and all of the borrowings under the Notes, are
denominated in U.S. dollars.

At June 30, 2000, borrowings under the Amended Credit Agreement bore interest
at a weighted average rate of 9.1% for U.S. borrowings and 8.47% for Canadian
borrowings per annum. The Notes bear interest at a rate of 9.6% per annum.

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

The Company currently believes that cash flow from operating activities,
together with revolving credit borrowings available under the Amended Credit
Agreement, will be sufficient to fund the Company's currently anticipated
working capital, capital spending and debt service requirements until the
maturity of the Revolving Facility (June 30, 2003), but there can be no
assurance in this regard. The Company expects that its working capital needs
will require it to obtain new revolving credit facilities at the time that
the Revolving Facility matures, by extending, renewing, replacing or
otherwise refinancing the Revolving Facility. No assurance can be given that
any such extension, renewal, replacement or refinancing can be successfully
accomplished.
