1. BASIS OF PRESENTATION

    The interim condensed consolidated financial statements included herein have
been prepared by Outsourcing Services Group, Inc. ("OSG" or the "Company")
without audit, pursuant to the rules and regulations of the Securities and
Exchange Commission (the "SEC"). Certain information and footnote disclosures,
normally included in financial statements prepared in accordance with generally
accepted accounting principles, have been condensed or omitted pursuant to such
SEC rules and regulations; nevertheless, the management of the Company believes
that the disclosures herein are adequate to make the information presented not
misleading. The financial statements should be read in conjunction with the
financial statements and related notes to the Company's 1999 Annual Report on
Form 10-K, as filed with the SEC.

    In the opinion of management, the condensed consolidated financial
statements included herein reflect adjustments consisting only of normal
recurring adjustments necessary to present fairly the consolidated financial
position of the Company as of July 1, 2000 and December 31, 1999 the results of
its operations for the three and six month period ended July 1, 2000 and
July 3, 1999 and its cash flows for the six month periods ended July 1, 2000 and
July 3, 1999. The results of operations for the interim periods are not
necessarily indicative of the results of operations for the full year.

2. NEW ACCOUNTING PRONOUNCEMENTS

    In 1998, the Financial Accounting Standards Board (FASB) issued SFAS
No. 133, "Accounting for Derivatives and Hedging Activities". SFAS No. 133, as
amended by SFAS No. 137, and SFAS No. 138 requires adoption by the company no
later than January 1, 2001. The Company plans to adopt SFAS No. 133 at that
time. The Company is currently evaluating the impact of the adoption of SFAS
No. 133 on the financial statements. In December 1999, the SEC issued Staff
Accounting Bulletin No. 101, "Revenue Recognition in Financial Statements"
("SAB 101"), which provided its views on applying generally accepted accounting
principles to selected revenue recognition issues. The Company is required to
adopt SAB 101 no later than January 1, 2001. The Company is currently evaluating
the impact of the adoption of SAB 101 on the financial statements.

4. CONTINGENCIES

    ENVIRONMENTAL REGULATION AND COMPLIANCE

    The Company's operations and properties are subject to extensive federal,
state, local and foreign environmental laws and regulations concerning among
other things, emissions to air, discharges to water, the remediation of
contaminated soil and groundwater, and the generation, handling, storage,
transportation, treatment and disposal of waste and other materials
(collectively, "Environmental Laws"). Violations of Environmental Laws can
result in civil or criminal penalties or in cease and desist or other orders
against the Company. In addition, the Company may be required to spend material
amounts to comply with Environmental Laws, and may be liable with respect to
contamination of sites currently or formerly owned or operated by the Company or
with respect to the off-site disposal of hazardous substances. Based upon the
Company's experience to date, as well as certain indemnification agreements
obtained in connection with the Kolmar Acquisition, the ASC acquisition and the
Piedmont acquisition, and certain insurance coverages, the Company believes that
the future cost of compliance with existing Environmental Laws and its liability
for identified environmental claims will not have a material adverse effect on
the Company's business, results of operations or financial condition. There can
be no assurance, however, that the Company's obligations in this regard will not
have such an effect or that the existing indemnities and insurance will be
sufficient to fund such liabilities. Furthermore, future events, such as new
information, or changes in Environmental Laws (or in their interpretation or
enforcement by courts or governmental agencies) may give rise to additional
costs or claims that could have a material adverse effect on the Company's
business, results of operations, financial condition or cash flows.

    Certain environmental laws, such as the Federal Comprehensive Environmental
Response, Compensation, and Liability Act of 1980, as amended ("CERCLA") and
analogous state laws, impose liability for the investigation and remediation of
hazardous substances released into the environment. Courts have interpreted
CERCLA to impose strict, and in some circumstances, joint and several, liability
on all potentially responsible parties ("PRPs") at a site if the harm is
indivisible, which means that one PRP could be held liable for the entire cost
of cleanup at a site where multiple parties contributed to the contamination. As
a practical matter, however, the costs typically are allocated, according to
volumetric or other standards, among the PRPs. Under CERCLA and analogous state
laws, the Company may incur liability for contamination at properties presently
or formerly owned or operated by the Company or its subsidiaries or predecessors
(including contamination caused by the Company's predecessors or prior owners or
operators of such sites), or at properties where such entities sent waste for
off-site treatment or disposal.

    In that regard, ASC's operations are located within the boundaries of the
Puente Valley Operable Unit ("OU") of the San Gabriel Valley Superfund Site.
Prior to the Company's purchase of ASC, the U.S. Environmental Protection Agency
("EPA") identified ASC as one of more than five hundred PRPs for the Puente
Valley OU. Subsequently, ASC and forty-three other PRPs entered into a consent
agreement to fund certain investigatory work, which work was completed in 1997.
To date, the EPA has not finally determined the remedial work that will be
required at the site; however, the EPA has issued estimates for the remedial
alternatives it is considering which range from approximately $28 million to
$51 million. In connection with the Company's purchase of ASC, the sellers (who
currently own the property on which ASC operates) agreed to indemnify the
Company with respect to the Puente Valley OU proceeding and certain other
environmental matters. Certain of the Company's leases with the sellers also
provide for off-sets to the Company's rental obligations in the event that the
Company incurs liability for such an

                                       8

                                  (UNAUDITED)

indemnified matter. Based on this indemnity, the lease off-set rights, recent
EPA cost estimates of the proposed cleanup alternatives and certain preliminary
estimates of ASC's share of liability, the Company believes, although there can
be no assurance, that ASC's liability at this site will not be material. In
addition, prior to the Company's merger with Aerosol Services Holding
Corporation ("ASHC"), the Los Angeles Regional Water Quality Control Board
("RWQCB") requested that ASC conduct certain soil and groundwater investigation,
this remediation began in the 2nd quarter of 2000. ASC has conducted the
requested investigations and the RWQCB has approved ASC's remediation plan.
Although there can be no assurance, the Company does not believe that the costs
of remediation will be material. This remediation is also the subject of the
above-referenced indemnity.

    Also, in regard to CERCLA, Kolmar and a former affiliate, Wickhen Products
("Wickhen"), have been identified as the two principal PRPs at the Carroll &
Dubies Superfund site in Port Jervis, New York. At the Carroll & Dubies site,
the remediation work was completed during 1999 and the final post-remediation
facility inspection was completed in December 1999. As of July 1, 2000,
$6.7 million of clean-up costs were incurred and funded through insurance.
Post-remediation monitoring, expected to cost $350,000 has commenced in the year
2000 and will continue through year 2005. The entire project has been, and will
continue to be, fully indemnified by CCL.

    Based on the advice of outside counsel, the Company also maintained an
accrual of $5,250,000 as of July 1, 2000 for one other site where Kolmar may
have liability for contamination caused by former operations, although it has
not yet been identified as a PRP and would have certain indemnification rights
for this site. The Company believes, based on a file review by an independent
consultant, that the accrual would be sufficient to fund all likely remediation
costs at the site.

    In addition, the Company maintained an accrual at July 1, 2000 of $750,000
for liabilities related to off-site waste disposal locations.

    While it is impossible at this time to determine with certainty the ultimate
outcome of the environmental matters referred to above, management believes that
adequate provisions have been made for probable losses with respect thereto and
that the ultimate outcome, after provisions therefore, will not have a material
adverse effect on the combined financial position of the Company. It is
reasonably possible that changes in estimates of recorded obligations and
related receivables may occur in the near term.

    Should any losses be sustained in connection with any of such environmental
matters in excess of provisions therefore, they will be charged against income
in the future.

    Piedmont's owned facility in Gainesville, Georgia is listed on the State of
Georgia's Hazardous Site Inventory ("HSI") of environmentally impacted sites due
to the detection of chlorinated solvents in the groundwater beneath the
facility. The Company is currently performing voluntary groundwater remediation.
The former owners of Piedmont have provided a partial indemnity for remediation
costs incurred at the facility. Based on this indemnity and the Company's
current estimates of reasonably possible remediation costs, the Company believes
that its liability for this site will not have a material adverse effect on the
Company.

    The Company also faces risks relating to federal and state environmental
regulation of VOCs. Recently enacted or future legislation requiring reductions
in the use of these materials could materially adversely affect the Company's
business if the industry does not develop material technology and product

                                       9

4. CONTINGENCIES (CONTINUED)
formulations to meet such future standards. California and New York recently
have mandated reductions in volatile organic chemicals in aerosol products, and
it is possible that Georgia and other states may in the future pass similar
legislation or enact regulations. All of the Company's products meet the current
regulatory standards, and management believes, although there can be no
assurance, that material technology and product formulations will be developed
that meet the future standards.

    LITIGATION--There are certain other legal proceedings and claims pending
against the Company arising out of the normal course of business which claims
for monetary damages are asserted. While it is not feasible to predict the
outcome of these legal proceedings and claims with certainty, management is of
the belief that any ultimate liabilities will not individually or in the
aggregate have an adverse effect on the Company's financial position or results
of operations.

5. BUSINESS ACQUISITION

    On February 29, 2000, pursuant to a stock purchase agreement dated
February 29, 2000, the Company acquired all of the issued and outstanding stock
of Precision Packaging and Services, Inc., an Ohio Corporation ("Precision"),
and the related real estate from the Susan L. Purkrabek Small Business Trust, an
electing small business trust, the David G. Knust Small Business Trust, an
electing small business trust and K.P. Properties, an Ohio general partnership
controlled by Ms. Purkrabek and Mr. Knust (the "Sellers") for approximately
$42.1 million. Precision is a contract manufacturer of consumer products (i.e.,
high speed liquid filling, cartoning, shrink wrapping, packaging) for some of
the largest U.S. consumer products companies. The Company plans for Precision to
continue in this line of business. The Company drew against its existing
revolving credit facility to pay Sellers.

    The acquisition has been accounted for as a purchase, and accordingly, the
purchase price was allocated to the net tangible and intangible assets acquired
based on estimated fair values at February 29, 2000. The excess purchase price
over the net assets and liabilities acquired was allocated to goodwill which is
being amortized over 15 years. The results of operations of Precision have been
included in the condensed consolidated financial statements since the
acquisition date.

6. SUPPLEMENTAL GUARANTOR INFORMATION

    The payment obligations of the Company under the Notes are guaranteed by
certain of the Company's wholly owned domestic subsidiaries ("Guarantors"). Such
guarantees are full, unconditional and joint and several. Separate financial
statements of the Guarantors are not presented because the Company's management
has determined that they would not be material to investors. The following
financial information presents the condensed combined balance sheets as of
July 1, 2000 and the condensed combined statements of operations and cash flows
for the six month period ended July 1, 2000 of the Guarantors, representing
Kolmar, ASC, Piedmont, Acupac, and Precision and the non-guarantors which
consist of Kolmar Canada, Kolmar de Mexico S.A. de C.V. and Kolmar (Aust.) Pty.
Limited. The financial information is intended to provide information for the
Guarantor and non-guarantor operations of the Company, based on amounts derived
from the financial statements of the Company and of the Kolmar Group, for the
six month period ended July 1, 2000.

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

GENERAL

    The Company is a leading provider of outsourced manufacturing and packaging
services to the health and beauty aid, household, and automotive consumer
product markets in North America. OSG primarily manufactures and/or packages
health and beauty aid products, such as colored cosmetics, lipsticks, facial
powders, skin care creams and lotions, hair spray and gel, hair mousse, shampoo,
and shaving cream and gel. Other products manufactured and packaged by the
Company include household and automotive products, such as lubricants, tire
sealers, cleaners, and lighter fluid. OSG offers its customers a complete range
of services, including product development, formulation, blending,
manufacturing, filling, and packaging. It also provides ancillary services such
as materials procurement, warehousing, and distribution of finished goods.

RESULTS OF OPERATIONS

    For the six and three month periods ended July 1, 2000 compared to the six
and three month periods ended July 3, 1999.

    NET REVENUE.  Revenues of $142.7 and $74.5 million for the six month and
three month periods ended July 1, 2000 increased by approximately $10.0 million
(7.5%) and $5.5 million (8.0%), respectively, from the prior 1999 periods. The
increases for the six and three month periods are primarily attributable to the
acquisitions of Acupac and Precision which contributed $8.2 million and
$12.8 million respectively for a net revenue increase of $21.0 million for the
six months ended July 1, 2000, offset by a decrease in sales of $11.0 million
which was higher in the first six months of 1999 due to a new line of color
cosmetics for a large domestic customer.

    COST OF GOODS SOLD.  Cost of goods sold of $121.8 million and $63.5 million
for the six and three month periods ended July 1, 2000, increased by
approximately $9.0 million (8.0%) and $5.0 million (8.6%), respectively, from
the prior 1999 periods. Total cost of goods sold, as a percentage of sales,
increased slightly to 85.4% and 85.2% for the six and three month periods from
85.0% and 85.0% from the prior 1999 periods. The increase was attributable to
the acquisition of Acupac and Precision. They contributed $7.6 million and
$10.7 million respectively, to the cost of goods sold for the six months ended
July 1, 2000, offset by a decrease in cost of goods sold of $9.3 million.

    SG&A EXPENSES.  Selling, general and administrative expenses ("SG&A") of
$12.9 million and $6.5 million for the six and three month periods ended
July 1, 2000, increased by approximately $1.0 million (8.6%) and increased by
$0.6 million (11.0%), respectively, from the prior 1999 periods. The increase
was attributable to the acquisition of Acupac and Precision their total SG&A was
$1.4 million and $1.0 million, respectively, for the six months ended July 1,
2000. As a percentage of net revenues, SG&A increased slightly to 9.0% and 8.7%,
respectively, for the six and three month periods ended July 1, 2000.

    INTEREST EXPENSE.  Interest expense of $8.0 million and $4.3 million for the
six and three month periods ended July 1, 2000, increased by approximately
$1.3 million (20.4%) and $1.0 million (31.1%), respectively, from the prior 1999
periods. Total indebtedness increased $46.9 million from $105.0 million at
July 3, 1999 to $151.9 million at July 1, 2000. The increase in debt and related
interest expense was primarily attributable to the acquisition of Precision on
February 29, 2000.

LIQUIDITY AND CAPITAL RESOURCES

    As of July 1, 2000, OSG had cash and cash equivalents of $2.0 million,
working capital of $35.5 million and long-term debt of $151.9 million. The
primary sources of cash were from financing activities due to the

                                       15
<PAGE>
acquisition of Precision on February 29, 2000. Principal uses of cash were for
capital expenditures, acquisition, and interest payments. Cash provided by (used
in) operations was $5.3 million and ($6.8) million for the six month period
ended July 1, 2000 and July 3, 1999, respectively.

    The Company anticipates that its primary uses of working capital in future
periods will be to service its indebtedness and provide funds for operations and
future acquisitions. Should the Company seek to acquire additional businesses,
it will have to incur additional indebtedness and possibly raise additional
equity. The Company's ability to grow through acquisitions is dependent upon the
availability of such financing as well as the availability of acquisition
candidates and the terms on which such candidates may be acquired, which may be
adversely affected by competition for such acquisitions. The Company regularly
examines opportunities for strategic acquisitions or other companies or lines of
business. The Company historically has financed its acquisitions through a
combination of borrowings under bank credit facilities, seller provided
financing, internally generated cash flows and the issuance of equity and debt
securities and anticipates that it may from time to time issue additional debt
and/or equity securities either as direct consideration for such acquisitions or
to raise additional funds to be used (in whole or in part) in payment for
acquired businesses or assets. There can be no assurance as to whether or when
any acquired business would contribute positive operating results commensurate
with the associated acquisition cost.

    The Company believes that cash on hand, cash flow from operations and
available borrowings under the Senior Secured Credit Facility will be sufficient
to meet the Company's presently anticipated working capital and capital
expenditure needs through fiscal June 30, 2001.

    The Company's capital expenditures are expected to increase slightly from
historical levels. The Company's capital expenditures will be primarily for
replacements of existing assets, new customer requirements, and to upgrade
various manufacturing equipment and facilities in order to reduce manufacturing
costs.

CERTAIN TRENDS AND UNCERTAINTIES

    Historically, the Company has grown its business through acquisitions and
investments in its operations. The Company intends to continue during 2000 to
make significant investments in the growth of its business and to examine
opportunities for additional growth through acquisitions and strategic
investments. The impact of these decisions on future profitability cannot be
predicted with any certainty. The Company's commitment to growth may increase
its vulnerability to unforeseen downturns in its markets and shifts in
competitive conditions. However, the Company believes that significant
opportunities exist in the markets for each of its product lines and services,
and continued investment in its marketing and sales capabilities and product
development will enhance its opportunities for long term growth and
profitability.

YEAR 2000 COMPLIANCE

    We have not experienced any business interruptions or supplier delays from
year 2000 problems to date and have not discovered any year 2000 problems in
internal computer systems material to our operations. We intend to continue to
monitor our internal system for year 2000 problems. There can be no assurance,
however, that we or our suppliers may not face future problems as a result of
year 2000 issues.
