                           --------------------------
 
    Outsourcing Services Group, Inc. ("OSG" or the "Company") hereby offers,
upon the terms and subject to the conditions set forth in this prospectus (this
"Prospectus") and the accompanying Letter of Transmittal (the "Letter of
Transmittal," which together with this Prospectus constitute the "Exchange
Offer"), to exchange an aggregate principal amount of up to $105,000,000 of its
10 7/8% Series B Senior Subordinated Notes due 2006 (the "New Notes"), which
have been registered under the Securities Act of 1933, as amended (the
"Securities Act"), for a like principal amount of its issued and outstanding
10 7/8% Senior Subordinated Notes due 2006 (the "Old Notes" and, together with
the New Notes, the "Notes") from the holders (the "Holders") thereof. The terms
of the New Notes are identical in all material respects to the Old Notes except
(i) that the New Notes have been registered under the Securities Act, (ii) for
certain transfer restrictions and registration rights relating to the Old Notes
and (iii) that the New Notes will not contain certain provisions relating to
Liquidated Damages (as defined) to be paid to Holders of Old Notes under certain
circumstances relating to the timing of the Exchange Offer and other
registration requirements. The Company issued $105,000,000 aggregate principal
amount of Old Notes on March 3, 1998 pursuant to exemptions from, or
transactions not subject to, the registration requirements of the Securities Act
and applicable state securities laws (the "Offering").
 
    Interest on the Notes will be payable semiannually in arrears on March 1 and
September 1 of each year, commencing September 1, 1998, at the rate of 10 7/8%
per annum. For each Old Note accepted for exchange, the Holder of such Old Note
will receive a New Note having a principal amount equal to that of the
surrendered Old Note. The New Notes will bear interest from the most recent date
to which interest has been paid on the Old Notes or, if no interest has been
paid on the Old Notes, from March 3, 1998. Old Notes accepted for exchange will
cease to accrue interest from and after the date of consummation of the Exchange
Offer. Holders of Old Notes whose Old Notes are accepted for exchange will not
receive any payment in respect of accrued interest on such Old Notes. The Notes
are redeemable in whole or in part, at the option of the Company, on or after
March 1, 2003 at the redemption prices set forth herein plus accrued and unpaid
interest to the redemption date. In addition, at any time on or prior to March
1, 2001, the Company, at its option may redeem up to 35% of the aggregate
principal amount of the Notes originally issued with the net cash proceeds of
one or more Equity Offerings (as defined), at the redemption price equal to
110.875% of the aggregate principal amount to be redeemed plus accrued and
unpaid interest to the redemption date; PROVIDED that at least 65% of the
aggregate principal amount of the New Notes issued hereunder together with the
Old Notes originally issued and not exchanged in the Exchange Offer remains
outstanding immediately after any such redemption.
 
    The Old Notes, are and the New Notes will be, unsecured senior subordinated
obligations of the Company and the Old Notes are, and the New Notes will be,
subordinated in right of payment to all existing and future Senior Debt (as
defined) of the Company. The Old Notes are, and the New Notes will be,
effectively subordinated to all secured indebtedness of the Company to the
extent of the assets securing such indebtedness. The Old Notes are, and the New
Notes will be, guaranteed on a full, unconditional, joint and several and
unsecured senior subordinated basis (the "Guarantees") by each of the current
United States subsidiaries, all of which are wholly-owned by the Company, and
certain future subsidiaries of the Company (the "Guarantors"). Each of the
Guarantees will be effectively subordinated to all secured indebtedness of such
Guarantor to the extent of the assets securing such indebtedness. The Old Notes
and the Guarantees rank PARI PASSU with, and the New Notes and their Guarantees
will rank PARI PASSU with, any future senior subordinated indebtedness of the
Company or the Guarantors, respectively and rank or will rank, as the case may
be, senior in right of payment to all other subordinated obligations of the
Company or the Guarantors, respectively. As of June 27, 1998, neither the
Guarantors nor the Company had outstanding Guarantor Senior Debt (as defined) or
Senior Debt, respectively, and the Guarantors had approximately $52.1 million of
availability under the Senior Secured Credit Facility (as defined). In addition,
as of June 27, 1998, the Company's subsidiaries that are not Guarantors had
approximately $5.9 million of indebtedness and accrued liabilities, including
trade payables, which are structurally senior to the Notes. See "Description of
Notes."
 
    Upon the occurrence of a Change of Control (as defined), each holder of
Notes will have the right to require that the Company purchase all or a portion
of such holder's Notes at a purchase price equal to 101% of the principal amount
thereof, plus accrued and unpaid interest to the date of purchase. In addition,
the Company will be obligated to offer to purchase the Notes at 100% of the
principal amount thereof, plus accrued and unpaid interest thereon, if any, to
the date of purchase in the event of certain asset sales. See "Description of
Notes."

THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
     EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE
         SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES
           COMMISSION PASSED UPON THE ACCURACY OR ADEQUACY OF THIS
               PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS
                            A CRIMINAL OFFENSE.

<PAGE>
(CONTINUED FROM PREVIOUS PAGE)
 
    The New Notes are being offered hereunder in order to satisfy certain
obligations of the Company contained in the Registration Rights Agreement (as
defined herein). Based on interpretations by the staff of the Securities and
Exchange Commission (the "Commission"), as set forth in no-action letters issued
to third parties, the Company believes that New Notes issued pursuant to the
Exchange Offer in exchange for Old Notes may be offered for resale, resold and
otherwise transferred by Holders thereof (other than any Holder which is an
"affiliate" of the Company within the meaning of Rule 405 under the Securities
Act), without compliance with the registration and prospectus delivery
requirements of the Securities Act, provided that such New Notes are acquired in
the ordinary course of such Holder's business and such Holder, other than
broker-dealers, has no arrangement with any person to engage in a distribution
of such New Notes. The Company has not sought and does not intend to seek its
own no-action letter in connection with the Exchange Offer and there can be no
assurance that the Commission would make a similar determination with respect to
the Exchange Offer. Each Holder, other than a broker-dealer, must acknowledge
that it is not engaged in, and does not intend to engage in, a distribution of
such New Notes and has no arrangement or understanding to participate in a
distribution of New Notes. If any holder is an affiliate of the Company and is
engaged in or intends to engage in or has any arrangement with any person to
participate in the distribution of the New Notes to be acquired pursuant to the
Exchange Offer, then such Holder (i) could not rely on the applicable
interpretations of the staff of the Commission and (ii) must comply with the
registration and prospectus delivery requirements of the Securities Act in
connection with any resale transaction. Each broker-dealer that receives New
Notes for its own account pursuant to the Exchange Offer must acknowledge that
it will deliver a prospectus in connection with any resale of such New Notes.
The Letter of Transmittal states that by so acknowledging and by delivering a
prospectus, a broker-dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act. This Prospectus, as it
may be amended or supplemented from time to time, may be used by a broker-dealer
in connection with resales of New Notes received in exchange for Old Notes where
such Old Notes were acquired by such broker-dealer as a result of market-making
activities or other trading activities. The Company has agreed that, for a
period of 90 days after the Expiration Date (as defined herein), it will make
this prospectus available to any broker-dealer for use in connection with any
such resale. See "Plan of Distribution."
 
    The Company will not receive any proceeds from the Exchange Offer. The
Company will pay all the expenses incident to the Exchange Offer. Tenders of Old
Notes pursuant to the Exchange Offer may be withdrawn at any time prior to the
Expiration Date. If the Company terminates the Exchange Offer and does not
accept for exchange any Old Notes, the Company will promptly return the Old
Notes to the Holders thereof. See "The Exchange Offer."
 
    There is no existing trading market for the New Notes, and there can be no
assurance regarding the future development of a market for the New Notes. BT
Alex. Brown Incorporated ("BT") has advised the Company that it currently
intends to make a market in the New Notes. BT is not obligated to do so,
however, and any market-making with respect to the New Notes may be discontinued
at any time without notice. The Company does not intend to apply for listing or
quotation of the New Notes on any securities exchange or to register or qualify
the New Notes for offer and sale in any jurisdiction (other than the
registration of the New Notes under the Securities Act).
 
    THE EXCHANGE OFFER IS NOT BEING MADE TO, NOR WILL THE COMPANY ACCEPT
SURRENDERS FOR EXCHANGE FROM, HOLDERS OF OLD NOTES IN ANY JURISDICTION IN WHICH
THE EXCHANGE OFFER OR THE ACCEPTANCE THEREOF WOULD NOT BE IN COMPLIANCE WITH THE
SECURITIES OR BLUE SKY LAWS OF SUCH JURISDICTION.
 
    The New Notes will be available initially only in book-entry form. The
Company expects that the New Notes issued pursuant to the Exchange Offer will be
issued in the form of one or more Global Notes (as defined) that will be
deposited with, or on behalf of, the Depository Trust Company ("DTC" or the
 
                                       i
<PAGE>
"Depository") and registered in its name or in the name of Cede & Co., as its
nominee. Beneficial interests in the Global Note representing the New Notes will
be shown on, and transfers thereof will be effected only through, records
maintained by the Depository and its participants. So long as DTC or its nominee
is the registered owner or holder of the Global Note, DTC or such nominee, as
the case may be, will be considered the sole owner or holder of the Notes
represented by such Global Note for all purposes under the Indenture (as
defined). Payments of the principal of, premium (if any), interest and
Liquidated Damages (if any) on, the Global Note will be made to DTC or its
nominee, as the case may be, as the registered owners thereof. None of the
Company, the Trustee (as defined) or any Paying Agent (as defined) will have any
responsibility or liability for any aspect of the records relating to or
payments made on account of beneficial ownership interests in the Global Note or
for maintaining, supervising or reviewing any records relating to such
beneficial ownership interest. After the initial issuance of such Global Note,
New Notes in certificated form will be issued in exchange for the Global Note
only in accordance with the terms and conditions set forth in the Indenture. See
"Description of Notes--Book Entry; Delivery and Form."

filing) (i) all quarterly and annual financial information that would be

certified independent accountants and (ii) all reports that would be required to
be filed with the Commission on Form 8-K if the Company were required to file

the Company has agreed to make available to any prospective purchaser of the
Notes or beneficial owner of the Notes in connection with any sale thereof the
information required by Rule 144A(d)(4) under the Securities Act.

                                  THE COMPANY
 
    The Company is a leading provider of outsourced manufacturing and packaging
services to the North American health and beauty aid market on the basis of
sales. Over 75% of the Company's revenues are derived from the manufacturing and
packaging of health and beauty aid products, including lipstick, face powder,
eye shadow, mascara, nail enamel, skin care cream and lotion, hair spray and
gel, shampoo and shaving cream and gel. Other products manufactured and packaged
by the Company include household and automotive products such as lubricant,
household cleaners and lighter fluid. OSG offers its customers a complete range
of services, including product conceptualization, formulation, manufacturing,
filling and packaging. It also provides ancillary services such as materials
procurement, warehousing and distribution of finished goods. The Company has
developed hundreds of proprietary products that have been placed into
distribution by its customers in national and international consumer markets.
Management estimates that a majority of the Company's revenues are derived from
products that OSG has formulated. The Company has six manufacturing facilities
strategically located in the United States and Canada, in addition to facilities
in Australia and Mexico. Management believes OSG is the largest independent
contract manufacturer and packager of color cosmetics, high-end salon aerosol
hair care products and shaving creams and gels in North America. The Company had
revenues of $79.8 million, $110.3 million and $115.0 million for the years ended
December 31, 1996 and 1997 and for the six month period ended June 27, 1998,
respectively. The Company had net losses of $6.2 million, $1.5 million and $2.2
million for the years ended December 31, 1996 and 1997 and for the six month
period ended June 27, 1998, respectively.
 
   
    The Company's customers include over 350 companies that market branded
and/or private label consumer products in the health and beauty aid, household
and automotive markets. Customers include Mary Kay, Sebastian and WD-40, as well
as other nationally branded marketers and numerous regional or niche marketers.
The Company's top ten customers have been with the Company for 17 years on
average, and nine of those top ten have been customers for at least ten years.
The Company believes that its ability to develop long-term relationships is due
to its product formulation expertise, manufacturing reliability, consistent
product quality and timely delivery. Many of OSG's customers lack in-house
manufacturing capabilities and outsource their manufacturing and packaging
requirements in order to focus on marketing. Management estimates that a
majority of the Company's revenues are derived from customers that do not have
in-house manufacturing capabilities for the products OSG manufactures. Companies
with the

necessary in-house manufacturing capabilities utilize the Company's services for
new product launches, lower volume brands and to supplement internal capacity.
 
    Contract manufacturers and packagers manufacture products to customer
specifications and fill containers for a wide range of industries. Contract
manufacturers typically charge a per-unit fee which varies depending on: (i) the
type of product, (ii) the type of services provided (filling only versus product
development, formulation, materials procurement, etc.), (iii) the container size
and order quantity, and (iv) the complexity of the manufacturing and packaging
process. The contract manufacturing and packaging industry is highly fragmented,
with hundreds of independent companies typically providing a narrow scope of
services in limited geographic areas. Competition is based principally on
formulation capabilities, product quality, reputation, service, dependability,
and cost-effectiveness. When the cost of distribution is a significant factor in
the total product cost or if customers desire geographic proximity to suppliers,
competition tends to be regionally based. Management believes that few
competitors offer the scale, expertise, reputation and range of services that
the Company provides.
 
    The Company specializes in the manufacturing and packaging of color
cosmetic, aerosol, cream, lotion and liquid products:
 
    COLOR COSMETIC PRODUCTS.  Color cosmetic products include lipstick, face
powder, eye shadow, mascara and nail enamel. The Company manufactures and
packages color cosmetics for the entire range of cosmetic market sectors from
budget to high-end. Management estimates that retail revenues in the color
cosmetics industry were approximately $3.3 billion in 1996 (representing an
approximate 3.6% annual growth rate since 1993). In order to respond to and
drive fashion trends, marketers continually change their product offerings. By
offering product conceptualization and formulation expertise and manufacturing
flexibility, the Company helps its customers remain current with market trends.
Management believes that the Company is the largest independent contract
manufacturer of color cosmetics in North America. For the three month period
ended March 28, 1998, OSG's revenues from color cosmetic products were $15.1
million, representing approximately 28.1% of revenues.
 
    AEROSOL PRODUCTS.  Aerosol products include a broad range of products such
as hair spray, shaving cream and gel, lubricant, non-stick cooking spray and
household cleaning products. The aerosol system is one of the most effective
forms of delivering products in a cost-effective manner, while providing dosage
control, sanitary use and convenience. Management estimates that in 1996, over
approximately 3.2 billion aerosol units were filled in the United States
(representing an approximate 1.8% annual growth rate since 1990). The aerosol
products market has undergone significant change as certain states have enacted
regulations requiring reduced Volatile Organic Chemicals ("VOC") emissions,
resulting in the reformulation of aerosol products to meet these new standards.
The Company has reformulated over 100 products in response to legislative
changes. Not only must packagers of aerosol products obtain government permits,
but the packaging process also requires specialized equipment and expertise.
Management believes that the Company is the second largest independent aerosol
contract manufacturer and packager in North America, the largest in shaving
creams and gels and the largest in high-end salon aerosol hair care products.
For the three month period ended March 28, 1998, OSG's revenues from aerosol
products were $22.9 million, representing approximately 42.5% of revenues.
 
    CREAM, LOTION AND LIQUID PRODUCTS.  Creams and lotions consist of skin care
products such as facial preparations, hand and body care products, sun care and
anti-aging products. According to management, the skin care market is one of the
largest and fastest growing sectors of the health and beauty aid market,
estimated at approximately $6 billion in revenues in 1996 (representing an
approximate 7.5% annual growth rate since 1993). The Company began emphasizing
skin care products in 1994 after recognizing the growth potential of this
market, and such products have grown to approximately 20% of the Company's
revenues. Other liquid products manufactured and packaged by OSG include
shampoo, conditioner, fragrance, pump hair spray and gel and non-aerosol
deodorant, as well as products for the household and automotive markets such as
lighter fluid, lubricant and cleaning products. For the six month period ended
 
                                       2
<PAGE>
March 28, 1998, OSG's revenues from cream, lotion and liquid products were $15.9
million, representing approximately 29.5% of revenues.
 
                             COMPETITIVE STRENGTHS
 
    OSG attributes its leading market position to the following factors: (for a
more detailed description see "Business--Competitive Strengths")
 
    FORMULATION EXPERTISE.  OSG's research and development chemists have
developed hundreds of proprietary products on behalf of its customers that have
been placed into distribution. In addition, OSG is at the forefront of the
reformulation of aerosol products in response to changing government
regulations. Management believes that the Company's formulation expertise is
highly valued by its customers, resulting in greater customer loyalty and the
opportunity for revenue growth. Management estimates that a majority of the
Company's revenues are derived from products that OSG has formulated.
 
   
    LONG-STANDING CUSTOMER RELATIONSHIPS.  OSG provides contract manufacturing
and packaging services to over 350 customers worldwide. OSG's top ten customers
have been customers for over 17 years on average, and include, among others,
Mary Kay, Sebastian, and WD-40. All but one of the top-ten customers have used
the Company's services for more than ten years.
    
 
    LEADER IN NICHE MARKETS.  The Company focuses on market sectors requiring
specialized manufacturing and/or formulation capabilities such as color
cosmetics, high-end salon aerosol hair care products and shaving creams and
gels. As a result of its value-added manufacturing and formulation services,
management believes that it is able to retain customers and obtain higher profit
margins than contract packagers who focus primarily on commodity-type products.
 
   
    FULL SERVICE CAPABILITIES.  The Company offers a full array of services,
including materials procurement, blending, filling, packaging, warehousing and
distribution. OSG's size, capabilities and reputation make it one of the few
contract manufacturers and packagers in the health and beauty aid markets
capable of supporting large scale production runs and product launches for
customers such as Mary Kay.
    
 
    MANUFACTURING EXPERTISE.  The Company has the equipment and manufacturing
expertise required to manufacture and package a wide variety of color cosmetic,
aerosol, cream, lotion and liquid products while adhering to strict product
specifications for its customers. For example, the Company is able to fill
complex containers such as barrier packs (pressurized, non-aerosol containers),
which have made it a leader in manufacturing and packaging products such as
shaving gels. All four of the Company's facilities that manufacture and package
products for Procter & Gamble have been awarded Procter & Gamble's prestigious
Pinnacle Award for Good Manufacturing Practices.
 
    STRATEGIC LOCATIONS.  OSG's facilities are strategically located to service
regional, national and international customers. Management believes the Company
is the largest independent aerosol packager on the West Coast and in the
Southeast. OSG can manufacture and package various products at each of its
facilities, creating flexibility in servicing its geographically diverse
customers in a cost-effective manner. The Company's facilities in Mexico and
Australia serve the requirements of both international and local customers.
 
    EXPERIENCED MANAGEMENT TEAM.  OSG's management team, headed by the former
President of Kolmar, Christopher Denney, has extensive industry experience.
Members of senior management have spent a majority of their careers in the
packaging industry, averaging 24 years of experience. In addition, Walter K.
Lim, the founder of ASC, serves as Chairman of OSG, and Samuel D. Garretson, the
founder of Piedmont, serves as a director of OSG.

                               BUSINESS STRATEGY
 
    The Company intends to increase its sales and profitability by capitalizing
on its product conceptualization and formulation expertise and its
cost-effective, quality manufacturing capabilities. In addition, management
believes that it can continue to improve the Company's operating results by
implementing the following strategies: (for a more detailed description, see
"Business--Business Strategy")
 
    CAPITALIZE ON CROSS-SELLING OPPORTUNITIES.  The Company expects to increase
product penetration of its customer base by capturing business that previously
exceeded each of its subsidiaries' particular areas of expertise. For example,
the Company has developed proprietary color cosmetics formulations for
Sebastian, a customer that traditionally focused on hair care products, and
expects to offer color cosmetic products to other hair care product customers.
In addition, the Company can offer its aerosol capabilities to its color
cosmetics customers.
 
    CENTRALIZE SALES AND MARKETING.  The Company plans to centralize the
management of its sales efforts in order to improve communication with
customers, to cross-sell services to customers and to ensure uniform pricing and
sales strategies. The Company plans to establish a group specifically focused on
identifying market trends and assisting customers with new product ideas, as
well as promoting the Company through customer presentations, advertising and
trade shows. The centralized sales effort will enable the Company to serve
national accounts more effectively and to pursue customers located outside the
local marketing reach of the individual plants.
 
    INCREASE INTERNATIONAL PRESENCE.  OSG intends to capitalize on increased
international demand for cosmetic products by increasing its export sales and
selectively entering into joint ventures and licensing agreements. The Company
currently has licensing agreements in Japan, Korea, Thailand and Poland. In
addition, the Company plans to continue to develop its own "control"
brands--brands for which OSG owns the formulas and manufactures and packages the
products to its own specifications, leaving the marketing, promotion and
distribution to its customer.
 
    REDUCE MANUFACTURING COSTS.  The Company believes that the combination of
ASC, Kolmar and Piedmont will result in cost reductions from (i) allocating
production among facilities to better optimize the use of labor and equipment;
(ii) eliminating redundant administrative operations; and (iii) in certain
cases, purchasing larger amounts of raw materials on more favorable terms.
 
    PURSUE STRATEGIC ACQUISITIONS.  The Kolmar Acquisition represents a
continuation of OSG's strategy to provide more services to existing and
potential customers in the highly fragmented contract manufacturing and
packaging industry. OSG plans to acquire companies that will provide additional
cross-selling and cost-reduction opportunities.

COMPANY HISTORY
 
    The Company currently owns and operates three wholly-owned subsidiaries:
ASC, Piedmont and Kolmar. Located in the City of Industry, California, ASC was
founded in 1966 by Walter K. Lim, OSG's Chairman. The Company acquired ASC on
February 14, 1994 for $35.0 million. Located in Gainesville, Georgia, Piedmont
was founded in 1985 by Samuel D. Garretson, a director of the Company. An
affiliate of the Company acquired Piedmont on September 30, 1996 for $14.1
million. Such affiliate was merged into the Company on June 30, 1997. Kolmar was
founded in 1921 and was acquired in 1991 by CCL Industries Inc. ("CCL"), a
publicly held Canadian contract packaging and manufacturing company. Kolmar's
main manufacturing facility is located in Port Jervis, New York, and other
smaller facilities are located in California, Pennsylvania, Canada, Mexico and
Australia.
 
THE KOLMAR ACQUISITION
 
    On January 9, 1998, OSG acquired from CCL and its wholly-owned indirect
subsidiary, CCL Industries Corporation ("CCL Industries"), all of the
outstanding shares of Kolmar Laboratories, Inc. and the net assets of Kolmar
Canada Inc. (the "Kolmar Acquisition"). The terms of the Kolmar Acquisition
Agreement (as defined) provide that the Kolmar Acquisition was effective as of
January 1, 1998 and the financial data presented herein gives effect to the
acquisition as of such date. Unless the context otherwise requires, references
to CCL include references to CCL Industries. The purchase price for the Kolmar
Acquisition was $78.0 million, subject to certain post-closing adjustments. In
conjunction with the Kolmar Acquisition, the Company refinanced all of its
existing indebtedness totaling $34.6 million. The purchase price and the
refinanced indebtedness, plus $7.4 million of fees and expenses, was financed
through $30.0 million of borrowings under the Senior Secured Credit Facility,
$70.0 million of borrowings under the senior subordinated credit agreement,
dated as of January 9, 1998, among the Company, Bankers Trust Company ("BTCo"),
as agent, and certain other parties (the "Subordinated Bridge Facility") and the
issuance of $20.9 million of the Company's common stock ("Common Stock") to
existing shareholders of the Company.

                               THE EXCHANGE OFFER
 
    On March 3, 1998, the Company issued $105.0 million aggregate principal
amount of Old Notes. The Old Notes were sold pursuant to exemptions from, or in
transactions not subject to, the registration requirements of the Securities Act
and applicable state securities laws, in order to enable the Company to raise
funds on a more expeditious basis than necessarily would have been possible had
the initial sale been pursuant to an offering registered under the Securities
Act. BT, as a condition to its purchase of the Old Notes, requested that the
Company agree to commence the Exchange Offer following the Offering.
 
<TABLE>

                                only in integral multiples of $1,000. The issuance of the
                                New Notes is intended to satisfy obligations of the Company
                                and the Guarantors contained in the Registration Rights
                                Agreement, dated as of March 3, 1998, among the Company, the

                                Offer."

                                Old Notes pursuant to the Exchange Offer may be withdrawn at
                                any time prior to the Expiration Date. Any Old Note not

                                without expense to the tendering Holder thereof as promptly
                                as practicable after the expiration or termination of the

Federal Income Tax
  Considerations..............  The exchange pursuant to the Exchange Offer will not result
                                in any income, gain or loss to the Holders or the Company
                                for Federal income tax purposes. See "Certain Federal Tax
                                Consequences."
 
Use of Proceeds...............  There will be no proceeds to the Company from the exchange
                                pursuant to the Exchange Offer. See "Use of Proceeds" and
                                "Capitalization."
 
Exchange Agent................  U.S. Bank Trust National Association (formerly First Trust
                                National Association) (the "Exchange Agent") is serving as
                                exchange agent in connection with the Exchange Offer.
 
Shelf Registration
  Statement...................  Under certain circumstances, certain holders of Notes
                                (including holders of Old Notes who are not permitted to
                                participate in the Exchange Offer or holders who may not
                                freely resell New Notes received in the Exchange Offer) may
                                require the Company to file and cause to become effective, a
                                Shelf Registration Statement (as defined), which would cover
                                resales of Notes by such holders. See "Description of
                                Notes--Exchange Offer; Registration Rights."
</TABLE>
 
                      CONSEQUENCES OF EXCHANGING OLD NOTES
 
    Holders of Old Notes who do not exchange their Old Notes for New Notes
pursuant to the Exchange Offer will continue to be subject to the restrictions
on transfer of such Old Notes as set forth in the legend thereon as a
consequence of the issuance of the Old Notes pursuant to exemptions from, or in
transactions not subject to, the registration requirements of the Securities Act
and applicable state securities laws. In general, the Old Notes may not be
offered or sold, unless registered under the Securities Act, except pursuant to
an exemption from, or in a transaction not subject to, the Securities Act and
applicable state securities laws. Subject to certain limited exceptions, holders
of Old Notes who do not exchange their Old Notes for New Notes in the Exchange
Offer will no longer have registration rights with respect to their Old Notes.
The Company does not currently anticipate that it will register the Old Notes
under the Securities Act. See "Description of Notes--Exchange Offer;
Registration Rights." Based on interpretations by the staff of the Commission,
as set forth in no-action letters issued to third parties, the Company believes
that New Notes issued pursuant to the Exchange Offer in exchange for Old Notes
may be offered for resale, resold or otherwise transferred by Holders thereof
(other than any Holder which is an "affiliate" of the Company within the meaning
of Rule 405 under the Securities Act) without compliance with the registration
and prospectus delivery requirements of the Securities Act, provided that such
New Notes are acquired in the ordinary course of such Holder's business and such
Holder, other than a broker-dealer, has no arrangement with any person to
participate in the distribution of such New Notes. The Company has not sought
and does not intend to seek its own no-action letter in connection with the
Exchange Offer and there can be no assurance that the Commission would make a
similar determination with respect to the Exchange Offer. Each Holder, other
than a broker-dealer, must acknowledge that it is not engaged in, and does not
intend to engage in, a distribution of such New Notes and has no arrangement or
understanding to participate in a distribution of New Notes. Each broker-dealer
that receives New Notes for its own account in exchange for Old Notes must
acknowledge that such Old Notes were acquired by such broker-dealer as a result
of market-making activities or other trading activities and that it will deliver
this Prospectus in connection with any resale of such New Notes. See "Plan of
Distribution." In addition, to comply with the securities laws of certain
jurisdictions, it may be necessary to qualify for sale or register thereunder
the New Notes prior to offering or selling such New Notes. The Company has
agreed, pursuant to the Registration Rights Agreement, subject to certain
limitations specified therein, to register or qualify the New Notes for offer or
sale under all applicable state securities or Blue Sky laws before the time the
Registration Statement (of which this Prospectus forms a part) is declared
effective by the Commission. See "The Exchange Offer--Consequences of Exchanging
Old Notes" and "Description of Notes-- Exchange Offer; Registration Rights."

    The terms of the New Notes and the Old Notes are identical in all material
respects, except (i) that the New Notes have been registered under the
Securities Act, (ii) for certain transfer restrictions and registration rights
relating to the Old Notes and (iii) that the New Notes will not contain certain
provisions relating to Liquidated Damages to be paid to Holders of Old Notes
under certain circumstances relating to the timing of the Exchange Offer and to
other registration requirements. See "Description of Notes-- Exchange Offer;
Registration Rights." The New Notes will bear interest from the most recent date
to which interest has been paid on the Old Notes or, if no interest has been
paid on the Old Notes, from March 3, 1998. Accordingly, registered Holders of
New Notes on the relevant record date for the first interest payment date
following the consummation of the Exchange Offer will receive interest accruing
from the most recent date to which interest has been paid or, if no interest has
been paid, from March 3, 1998. Old Notes accepted for exchange will cease to
accrue interest from and after the date of consummation of the Exchange Offer.
Holders whose Old Notes are accepted for exchange will not receive any payment
in respect of interest on such Old Notes otherwise payable on any interest
payment date the record date for which occurs on or after consummation of the
Exchange Offer.

Offers to Purchase............  In the event of certain asset sales, the Company will be
                                required to offer to repurchase the New Notes to the extent
                                of the net cash proceeds from such asset sales at a price
                                equal to 100.0% of the principal amount of the New Notes,
                                plus accrued and unpaid interest, if any, to the date of

                                Covenants--Limitation on Asset Sales."
 
Guarantees....................  The New Notes will be guaranteed on a full, unconditional,
                                joint and several and senior subordinated basis by the
                                Guarantors. The Guarantees will be unsecured senior
                                subordinated obligations of the Guarantors and will be
                                subordinated in right of payment to all existing and future
                                Guarantor Senior Debt (including indebtedness under the
                                Senior Secured Credit Facility). As of June 27, 1998, the
                                Guarantors had no Guarantor Senior Debt outstanding and
                                approximately $52.1 million of availability under the Senior
                                Secured Credit Facility. See "Description of
                                Notes--Guarantees."
 
Ranking.......................  The New Notes will be unsecured senior subordinated
                                obligations of the Company and will be subordinated in right
                                of payment to all existing and future Senior Debt of the
                                Company. The New Notes will also be effectively subordinated
                                to all secured indebtedness of either the Company or any of
                                its subsidiaries to the extent of the assets securing such
                                indebtedness. The New Notes will rank PARI PASSU with any
                                future senior subordinated indebtedness of the Company and
                                will rank senior in right of payment to all other
                                subordinated obligations of the Company. As of June 27,
                                1998, the Company had no Senior Debt outstanding but has an
                                obligation to guarantee, on a senior basis, debt of the
                                Guarantors incurred under the Senior Secured Credit
                                Facility. In addition, as of June 27, 1998, the Company's
                                subsidiaries that are not Guarantors had approximately $5.9
                                million of indebtedness and accrued liabilities, including
                                trade payables, which would be structurally senior to the
                                New Notes. See "Description of Notes--Subordination."
 
Certain Covenants.............  The Indenture governing the New Notes (the "Indenture") will
                                contain certain covenants that limit the ability of the
                                Company and its subsidiaries to, among other things, incur
                                additional indebtedness, pay dividends or make certain other
                                Restricted Payments (as defined), consummate certain asset
                                sales, enter into certain transactions with affiliates,
                                incur liens, create restrictions on the ability of a
                                subsidiary to pay dividends or make certain payments, sell
                                or issue preferred stock of subsidiaries to third parties,
                                merge or consolidate with any other person or sell, assign,
                                transfer, lease, convey or otherwise dispose of all or
                                substantially all of the assets of the Company, and engage
                                in other lines of business. See "Description of
                                Notes--Certain Covenants."

       SUMMARY HISTORICAL AND UNAUDITED PRO FORMA COMBINED FINANCIAL DATA
 
    The summary financial data for the Company set forth below for the fiscal
years ended December 31, 1993, 1994, 1995, 1996 and 1997 are derived from the
audited financial statements of the Company and its predecessors. Such data for
the six months ended June 29, 1997 and June 27, 1998 are derived from the
unaudited interim financial statements of the Company, which include all
adjustments (consisting only of normal recurring adjustments) which the Company
considers necessary for a fair presentation of the results of operations for the
periods presented. The results for the six month period ended June 27, 1998 are
not necessarily indicative of the results to be expected for the year ending
December 31, 1998 or for any future period. OSG, previously Aerosol Services
Holding Corporation ("ASHC"), was formed to acquire ASC effective February 14,
1994. OSG had no operations prior to the acquisition. Consequently, the
financial data set forth below for the fiscal year ended December 31, 1994
includes the audited results of OSG for the period from inception, February 15,
1994 to December 31, 1994 and the unaudited balances of ASC for the period from
January 1, 1994 to February 14, 1994. Amounts in 1993 reflect the operating
results and financial position of ASC, prior to its acquisition by OSG.
 
    The summary financial data for Piedmont set forth below for the fiscal years
ended September 30, 1993, 1994, 1995 and 1996 are derived from the audited
financial statements of Piedmont. Such data for Kolmar for the fiscal years
ended December 31, 1995, 1996 and 1997 are derived from audited combined
financial statements. Kolmar financial data for the years ended December 31,
1993 and 1994 are derived from Kolmar's unaudited financial statements. The
unaudited financial statements for the years ended December 31, 1993 and 1994
include all adjustments (consisting only of normal recurring adjustments) which
management of Kolmar considers necessary for a fair presentation of the
financial data for the periods presented.
 
    The summary unaudited pro forma combined financial data of the Company for
the fiscal year ended December 31, 1997 are derived from the Unaudited Pro Forma
Condensed Combined Financial Data included elsewhere in this Prospectus. Such
data give effect to (i) the Kolmar Acquisition and the repayment of existing
debt of the Company in conjunction therewith; and (ii) the completion of the
Offering and application of the proceeds therefrom, as if each had occurred at
the beginning of the year ended December 31, 1997 and before changes in
accounting principles and extraordinary items.
 
    The following information should be read in conjunction with the "Selected
Historical Financial Data," "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and the financial statements of the
Company, Kolmar and Piedmont and the related notes thereto (collectively, the
"Financial Statements") included elsewhere in this Prospectus.

  NOTES TO SUMMARY HISTORICAL AND UNAUDITED PRO FORMA COMBINED FINANCIAL DATA
 
(a) The Piedmont and Kolmar acquisitions were effective on September 30, 1996
    and January 1, 1998, respectively. Consequently, the Company's Statements of
    Operations Data and Other Data for the year ended December 31, 1997 and for
    the six months ended June 27, 1998 (which includes the acquired operations
    for the entire period) are not directly comparable to the Statements of
    Operations Data and Other Data for the comparable periods in prior years.
    Additionally, the results of operations for the fiscal year ended December
    31, 1996 include the acquired operations for the three-month period
    subsequent to the Piedmont acquisition.
 
(b) Net income of OSG for the fiscal year ended December 31, 1993 reflects $5.5
    million of owners' bonus compensation prior to the acquisition of ASC by the
    Company. Net loss of OSG for the fiscal year ended December 31, 1996
    includes a $7.0 million charge associated with the cumulative effect of a
    change in accounting principle. Net loss for the year ended December 31,
    1997 and for the six months ended June 27, 1998 includes $1.1 million and
    $2.1 million of extraordinary items, respectively, net of tax, associated
    with charges for early retirement of debt.
 
(c) Adjusted EBITDA represents the sum of income from operations and
    depreciation and amortization. For the fiscal year ended December 31, 1993,
    the predecessor company to OSG paid its owners a bonus of $5.5 million. Such
    payment has not been reflected in adjusted EBITDA. In addition, adjusted
    EBITDA for the fiscal year ended December 31, 1993 excludes the loss from
    operations from a discontinued operation totaling $100,000. The assets of
    such operation were not purchased by OSG. Adjusted EBITDA for Kolmar
    excludes a write-off of goodwill of $12,963,000 and a charge for
    restructuring costs of $3,935,000 for the fiscal year ended December 31,
    1993 and a $24,100,000 write-down of assets for the fiscal year ended
    December 31, 1994.
 
    Adjusted EBITDA is not intended to represent cash flows from operations as
    defined by GAAP and should not be considered as an alternative to net income
    as an indicator of the Company's operating performance or to cash flows as a
    measure of liquidity. Adjusted EBITDA is included herein as it is a basis
    upon which the Company assesses its financial performance and its ability to
    service indebtedness. Adjusted EBITDA as calculated herein differs from the
    definition of the term "Consolidated EBITDA" used in the Indenture under
    which the New Notes are to be issued. See "Description of Notes--Certain
    Definitions."
 
(d) Piedmont and Kolmar use 52-53 week fiscal years. For presentation purposes,
    Piedmont's fiscal year has been reflected as if it ended on September 30.
    Kolmar's fiscal year has been reflected as if it ended on December 31.
 
(e) Net loss for Kolmar for the fiscal year ended December 31, 1993 reflects
    charges for restructuring costs of $3,935,000 and a write-off of $12,963,000
    of goodwill. Net loss for Kolmar for the fiscal year ended December 31, 1994
    reflects a $24,100,000 write-down of assets.
 
(f) See "Unaudited Pro Forma Condensed Combined Financial Data" for information
    related to pro forma adjustments.
 
(g) Unaudited pro forma combined interest expense includes amortization of
    deferred financing costs of $1.1 million for the fiscal year ended December
    31, 1997.
 
(h) Unaudited pro forma combined net income is computed excluding the effects of
    extraordinary items and the cumulative effects of a change in accounting
    principle.

<PAGE>
                                  RISK FACTORS
 
    HOLDERS OF OLD NOTES SHOULD CAREFULLY CONSIDER THE FOLLOWING SPECIFIC RISK
FACTORS, AS WELL AS THE OTHER INFORMATION SET FORTH IN THE PROSPECTUS, BEFORE
TENDERING THEIR OLD NOTES IN THE EXCHANGE OFFER.
 
SUBSTANTIAL LEVERAGE AND ABILITY TO SERVICE DEBT
 
    As a result of the Offering, the Company is highly leveraged. The Company's
indebtedness was $106.8 million and stockholders' equity was $12.8 million, as
of June 27, 1998. In addition, subject to the restrictions in the Senior Secured
Credit Facility and the Indenture, the Company and its subsidiaries may incur
additional indebtedness (including additional Senior Debt and Guarantor Senior
Debt) from time to time to finance acquisitions, working capital, capital
expenditures or other purposes. For the year ended December 31, 1997 and the six
month period ended June 27, 1998, the Company's ratio of earnings to fixed
charges were 1.02 and 1.18, respectively.
 
    The level of the Company's indebtedness could have important consequences to
holders of the Notes, including, but not limited to the following: (i) a
substantial portion of the Company's cash flow from operations must be dedicated
to debt service and will not be available for other purposes; (ii) the Company's
ability to obtain additional debt financing in the future for working capital,
capital expenditures, research and development or acquisitions may be limited;
(iii) to the extent that the Company's subsidiaries borrow under the Senior
Secured Credit Facility, they do so at floating rates of interest which could
result in higher interest expense in the event of an increase in interest rates;
and (iv) the Company's substantial leverage may make it more vulnerable to
adverse economic conditions and may limit its ability to withstand competitive
pressures or take advantage of business opportunities. Certain of the Company's
competitors are currently less leveraged and may have significantly greater
operating and financing flexibility than the Company.
 
    The Company's ability to pay principal and interest on the Notes and to
satisfy its other debt obligations will depend upon the future operating
performance of its subsidiaries, which will be affected by prevailing economic
conditions and financial, business and other factors, certain of which are
beyond their control, as well as the availability of borrowings under the Senior
Secured Credit Facility or a successor facility. The Company currently
anticipates that its operating cash flow, together with borrowings by its
subsidiaries under the Senior Secured Credit Facility, will be sufficient to
meet its operating expenses and to service its debt requirements as they become
due. If the Company is unable to service its indebtedness, it will be forced to
take actions such as reducing or delaying capital expenditures, selling assets,
restructuring or refinancing its indebtedness (which could include the Notes),
or seeking additional debt or equity capital. There is no assurance that any of
these remedies can be effected on satisfactory terms, if at all. Factors which
could affect the Company's or its subsidiaries' access to the capital markets,
or the cost of such capital, include changes in interest rates, general economic
conditions, the perception in the capital markets of the Company's business,
results of operations, leverage, financial condition and business prospects. In
addition, the Senior Secured Credit Facility and the covenants with respect to
the Notes significantly restrict the Company's and its subsidiaries' ability to
incur additional indebtedness, including refinancing indebtedness, and to sell
assets. See "Capitalization," "Management's Discussion and Analysis of Financial
Condition and Results of Operations," "Description of the Senior Secured Credit
Facility" and "Description of Notes."
 
HOLDING COMPANY STRUCTURE; EFFECTS OF ASSET ENCUMBRANCE
 
    The Company is a holding company whose only material assets are the stock of
its subsidiaries. The Company's cash flow and, consequently, its ability to
service debt, including the Notes, is dependent upon the earnings of its
subsidiaries and the payment of funds by those subsidiaries to the Company in
the form of loans, dividends or otherwise. There can be no assurance that any
such payments will be adequate to fund the interest and principal payments on
the Notes when due. The Old Notes are, and the New Notes
 
                                       14
<PAGE>
will be, guaranteed on a full, unconditional, joint and several and unsecured
senior subordinated basis by the Guarantors and, as a result, should the Company
fail to satisfy any payment obligation under the Notes, the holders would have a
direct claim therefor against the Guarantors. However, the Guarantors are
obligors with respect to substantial indebtedness, including in their capacity
as borrowers under the Senior Secured Credit Facility on a senior basis, and the
capital stock of the Guarantors is pledged to secure amounts borrowed
thereunder. Accordingly, there may be insufficient assets remaining after
payment of senior and/or secured claims to pay amounts due on the Notes. The
Company's non-Guarantor subsidiaries are separate and distinct legal entities
and have no obligation, contingent or otherwise, to pay any amounts due pursuant
to the Notes or to make funds available therefor, whether in the form of loans,
dividends or otherwise. The Indenture will permit the Company and its
subsidiaries (including non-Guarantor subsidiaries) to incur additional
indebtedness, subject to certain restrictions. See "Description of
Notes--Certain Covenants--Limitation on Incurrence of Additional Indebtedness."
Any right of the Company to participate in any distribution of the assets of any
of the non-Guarantor subsidiaries upon the liquidation, reorganization or
insolvency of such subsidiary (and the consequent availability of such assets to
service indebtedness of the Company, including under the Notes) will be subject
to the claims of creditors (including trade creditors) and preferred
stockholders, if any, of such non-Guarantor subsidiary, except to the extent
that the Company has a claim against such non-Guarantor subsidiary as a creditor
of such non-Guarantor subsidiary. Moreover, the payment of dividends and the
making of loan advances to the Company by its subsidiaries are subject to
restrictive covenants in agreements entered into by certain of such subsidiaries
including under the Senior Secured Credit Facility, and may be restricted upon
an event of default thereunder. The Guarantee of the Notes by any Guarantor will
be discharged upon the sale of such Guarantor in accordance with the provisions
of the Indenture. See "Description of Notes-- Guarantees."
 
SUBORDINATION OF THE NOTES AND THE GUARANTEES
 
    The Notes and the Guarantees will be subordinated in right of payment to all
existing and future Senior Debt of the Company and to all existing and future
Guarantor Senior Debt of the Guarantors, (including borrowings under the Senior
Secured Credit Facility), respectively. In the event of the bankruptcy,
liquidation or reorganization of the Company, the assets of the Company or the
Guarantors will be available to pay obligations on the Notes only after all
Senior Debt of the Company and all Guarantor Senior Debt of the Guarantors, as
the case may be, has been paid in full. Any assets of the Company or the
Guarantors which may remain may not be sufficient to pay the amounts due on the
Notes then outstanding. The Notes will also be effectively subordinated to all
secured indebtedness of either the Company or any of its subsidiaries to the
extent of the assets securing any such indebtedness. As of June 27, 1998,
neither the Guarantors nor the Company had Guarantor Senior Debt or Senior Debt,
respectively, outstanding and the Guarantors had approximately $52.1 million of
availability under the Senior Secured Credit Facility. The Company has an
obligation to guarantee, on a senior basis, all amounts borrowed by its
subsidiaries under the Senior Secured Credit Facility. As of June 27, 1998,
subsidiaries of the Company that are not Guarantors, had approximately $5.9
million of indebtedness and accrued liabilities, including trade payables, which
would have been structurally senior to the Notes. Additional Senior Debt may be
incurred by the Company and additional Guarantor Senior Debt may be incurred by
the Guarantors from time to time, subject to certain restrictions.
 
    The Company may not pay principal of, premium, if any, or interest on or
other amounts owing in respect of the Notes, make any deposit pursuant to any
defeasance provisions or repurchase, redeem or otherwise retire any of the Notes
if certain Senior Debt or Guarantor Senior Debt is not paid when due or any
other default on such Senior Debt or Guarantor Senior Debt occurs and the
maturity of such debt is accelerated in accordance with its terms unless, in
either case, the default has been cured or waived, any such acceleration has
been rescinded or such debt has been paid in full. Moreover, under certain
circumstances, if any non-payment default exists with respect to Designated
Senior Debt (as defined) which would permit the holders of such Designated
Senior Debt to accelerate the maturity thereof, the
 
                                       15
<PAGE>
Company may not make any payments on the Notes for a specified time, unless such
default is cured or waived, or such Designated Senior Debt is paid in full. See
"Description of Notes--Subordination" and "Description of the Senior Secured
Credit Facility." The holders of the Notes will have no direct claim against the
Guarantors other than the claim created by the Guarantees. The rights of holders
of the Notes to participate in any distribution of assets of any Guarantor upon
liquidation, bankruptcy or reorganization may, as is the case with other
unsecured creditors of the Company, be subject to prior claims against such
Guarantor. The Guarantees may themselves be subject to legal challenge in the
event of the bankruptcy or insolvency of a Guarantor, or in certain other
circumstances. If such a challenge were upheld, the Guarantees would be
invalidated and unenforceable. See "--Fraudulent Transfer Considerations."
 
RESTRICTIONS IMPOSED BY TERMS OF THE COMPANY'S INDEBTEDNESS AND WARRANT
  AGREEMENT
 
    The Indenture will restrict, among other things, the Company's and its
subsidiaries' ability to: incur additional indebtedness; incur liens; pay
dividends or make certain other restricted payments; consummate certain asset
sales; enter into certain transactions with affiliates; incur indebtedness that
is subordinate in right of payment to any Senior Debt and senior in right of
payment to the Notes; create or cause to exist restrictions on the ability of a
subsidiary to pay dividends or make certain payments to the company; merge or
consolidate with any other person or sell, assign, transfer, lease, convey or
otherwise dispose of all or substantially all of the assets of the Company. See
"Description of Notes--Certain Covenants." In addition, the Senior Secured
Credit Facility contains other and more restrictive covenants and will prohibit
the Company in all circumstances from prepaying certain of its indebtedness
(including the Notes). The Senior Secured Credit Facility also requires the
Company to maintain specified financial ratios and to satisfy certain financial
condition tests. The Company's ability to meet those financial ratios and tests
can be affected by events beyond its control, and there can be no assurance that
the Company will meet those tests. A breach of any of these covenants could
result in a default under the Senior Secured Credit Facility and/or the
Indenture. Upon the occurrence of an event of default under the Senior Secured
Credit Facility, the lenders could elect to declare all amounts outstanding
under the Senior Secured Credit Facility, together with accrued interest, to be
immediately due and payable. If the Company's subsidiaries were unable to repay
those amounts, the lenders could proceed against the collateral granted to them
to secure that indebtedness or against the Company under its guarantee of the
Senior Secured Credit Facility. If the debt outstanding under the Senior Secured
Credit Facility were to be accelerated, there can be no assurance that the
assets of the Company and its subsidiaries would be sufficient to repay the
obligations under the Senior Secured Credit Facility, other Senior Debt,
Guarantor Senior Debt or the Notes. Substantially all the assets of the Company
and its subsidiaries are pledged as security under the Senior Secured Credit
Facility. See "Description of the Senior Secured Credit Facility."
 
    The Warrant Agreement (as defined) provides for certain anti-dilution rights
and restrictions on transferability and redemption of shares of Common Stock
from affiliates of the Company, in addition to certain registration, tag along,
drag along and preemptive rights. Further, without the prior consent of Chase
Manhattan (as defined), the Warrant Agreement prohibits (i) the Company and its
subsidiaries from repurchasing or redeeming shares of Common Stock, except for
shares repurchased or redeemed from management, other than on a PRO RATA basis
from all of the Company's shareholders and Chase Manhattan; (ii) the Company and
its subsidiaries from selling, leasing or otherwise transferring any property or
assets to, or purchasing, leasing or otherwise acquiring any property or assets
from, or otherwise engaging in any other transactions with, any of the Company's
affiliates, except (a) in the ordinary course, (b) transactions between or among
the Company and its wholly-owned subsidiaries, (c) any transactions existing as
of January 8, 1998 or (d) other transactions permitted by the Warrant Agreement;
(iii) the Company from entering into any agreement or instrument limiting in any
manner its ability to perform its obligations under the Warrant Agreement or the
Warrants, other than the Subordinated Bridge Facility and the Senior Secured
Credit Facility and any refinancing thereof (including the Notes); and (iv) the
Company from amending any provisions of the Company's employee stock option
plan, Stockholder Agreement (as defined) and organizational documents in any
manner that would have an adverse effect on Chase
 
                                       16
<PAGE>
Manhattan's rights under the Warrant (as defined), without the prior consent of
Chase Manhattan. See "Description of Certain Terms of the Preferred Stock and
the Warrant Agreement--Warrant Agreement."
 
INDUSTRY CONDITIONS AND COMPETITION
 
    The contract manufacturing and packaging industry is highly competitive. The
color cosmetic, aerosol, cream, lotion and liquid products sectors of this
industry are highly fragmented, with hundreds of independent contract
manufacturers typically providing a narrow scope of services in limited
geographic areas. Competitors include a large number of other contract
packagers, a few of which are larger than the Company and have substantially
greater resources. In addition, the Company's competitive position could be
adversely affected by any significant consolidation of companies operating in
the health and beauty aid, household and automotive products markets, and from
marketers with in-house manufacturing capabilities. In certain instances, the
Company's customers that have in-house manufacturing capabilities have increased
their own in-house manufacturing operations. Any significant increase in
in-house manufacturing by the Company's customers could adversely affect the
Company's business, results of operations or financial condition. See
"Business--Competition."
 
LACK OF COMBINED OPERATING HISTORY AND INTEGRATION OF ACQUISITIONS
 
    ASC, Piedmont and Kolmar do not have any consolidated financial operating
history. The Company's future operating results depend in large part on its
ability to integrate the business of Kolmar with its existing business. Even
though the Company intends to operate ASC, Piedmont and Kolmar as an integrated
entity, no assurance can be given that the integration of Kolmar or future
acquisitions will be successful or that the anticipated strategic benefits of
Kolmar or of future acquisitions will be realized. If the Company is unable
successfully to integrate Kolmar or future acquisitions, the Company's business,
results of operations or financial condition, may be adversely affected. The
assimilation of acquisitions, including the Kolmar Acquisition, requires certain
non-recurring expenditures. There can be no assurance that the operations
acquired will be sufficiently profitable to offset such expenditures, or that
the operations of the acquired companies (or the historical business of the
Company) will not be adversely affected as a result of any such acquisition.
 
   
    The Company has undertaken a strategy to consolidate a portion of the highly
fragmented contract packaging industry through acquisitions. Therefore, the
Company is continually involved in the investigation and evaluation of potential
acquisitions and at any time may be discussing possible transactions, conducting
due diligence investigations or otherwise pursuing acquisition opportunities. To
this effect, the Company may from time to time enter into letters of intent
regarding potential acquisitions which may or may not come to fruition. The
Company has entered into one non-binding letter of intent regarding its possible
acquisition of a company. This proposed transaction is still in the negotiation
stages and there can be no assurance that it will be consummated, and if so,
upon what terms. The Company historically has financed its acquisitions through
a combination of borrowings under bank credit facilities, seller-provided
financing, internally-generated cash flow and the issuance of equity securities.
The Company's future growth and financial success may depend upon a number of
factors, including, among others, its ability to identify acceptable acquisition
candidates, to consummate the acquisitions on favorable terms, improve the
financial performance of acquired companies and to integrate them into the
Company's operations and to attract and retain customers.
    
 
    The Company's ability to execute its growth strategy depends to a
significant degree upon its ability to obtain additional long-term debt and
equity capital. Other than borrowings by the Company's subsidiaries under the
Senior Secured Credit Facility, the Company has no commitments for additional
borrowings or sales of equity, and there can be no assurance that the Company
will be successful in consummating any such future financing transactions on
terms favorable to the Company, if at all.
 
                                       17
<PAGE>
ENVIRONMENTAL COMPLIANCE AND GOVERNMENT REGULATION
 
    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"). Based upon the
Company's experience to date, as well as certain indemnification agreements
obtained in connection with the Company's acquisitions, 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 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 or financial condition.
 
    Certain environmental laws, such as the federal Comprehensive Environmental
Response, Compensation, and Liability Act of 1980, as amended ("CERCLA") and
analogous state laws impose strict, and in some circumstances, joint and
several, liability for the investigation and remediation of hazardous substances
released into the environment and related damages to natural resources. In that
regard, the Company or its affiliates have been identified as potentially
responsible parties ("PRPs") at several sites currently under investigation by
the United States Environmental Protection Agency ("EPA") and similar state
agencies. Based on indemnities obtained in connection with the Company's
acquisitions and environmental insurance obtained with respect to Kolmar, as
well as presently available information regarding each such site, the Company
does not believe that its related liability will have a material adverse effect
on the Company's business, results of operations or financial condition. There
can be no assurance, however, that these matters will not have such an effect,
or that the Company will not incur liability at additional similar sites in the
future. See "Business--Environmental Issues, Compliance and Government
Regulation."
 
    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 propellants could materially adversely affect the Company's
business if the industry does not develop propellant technology and product
formulations to meet such future standards. California and New York recently
have mandated reductions in VOCs 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
propellant technology and product formulations will be developed that meet the
future standards. See "Business--Environmental Issues, Compliance and Government
Regulation."
 
    EMPLOYEE HEALTH AND SAFETY REGULATION.  The Company's operations are subject
to a variety of worker safety laws. The United States Occupational Safety and
Health Act of 1970 ("OSHA") and analogous laws mandate general requirements for
safe workplaces for all employees. The Company believes that its operations are
in material compliance with applicable employee health and safety laws.
 
    STATE AND FEDERAL REGULATION.  The Company's manufacturing and packaging of
over-the-counter pharmaceuticals, which accounts for a small percentage of
revenues, and cosmetics is subject to regulation by the Food and Drug
Administration ("FDA") and by various state agencies, especially the California
Department of Health Services. Any failure by the Company to remain in
compliance with the regulations promulgated by these agencies could have a
material adverse effect on the Company's business.
 
    The Company must also adhere to state and federal regulations governing
"good manufacturing practices," including testing, quality control,
manufacturing, inspection, and documentation requirements
 
                                       18
<PAGE>
for certain products. Although the Company has had no difficulty in complying
with these regulations to date, if violations of such regulations are noted
during inspections of the Company's manufacturing facilities, the Company may be
required or may elect to cease manufacturing and packaging at the facility in
violation, pending resolution of the violation. In these circumstances, the
Company may also be required or may elect to recall products that were
manufactured under improper conditions. Although the Company has had no
difficulty in complying with these regulations to date, there can be no
assurance that any future federal or state regulation of the Company's business
will not have a material adverse impact on the Company's business, financial
condition or results of operations.
 
    MINIMUM WAGES.  The Company utilizes local labor contractors at its various
facilities to provide a significant portion of its production labor force. The
Company is subject to the Fair Labor Standards Act as well as various federal,
state and local regulations that govern such matters as minimum wage
requirements, overtime and working conditions. A large number of the Company's
employees, including those provided by local labor contractors, are paid at or
just above the federal minimum wage level and, accordingly, changes in these
laws, regulations or ordinances could have a material adverse effect on the
Company by increasing the Company's costs.
 
DEPENDENCE ON KEY PERSONNEL
 
    The Company's success will continue to depend to a significant extent on its
executive officers and other key personnel, including certain development
chemists. The loss of the services of these key personnel could have a material
adverse effect on the Company, and there can be no assurance that the Company
would be able to find replacements with appropriate business experience and
skills. In addition, the success of any acquisition by the Company (including
the Kolmar Acquisition) may depend, in part, on the Company's ability to retain
management personnel of the acquired companies. The Company has entered into
employment agreements with certain of its executive officers and/or other key
employees. See "Management--Employment Agreements." The Company currently
maintains a "key man" insurance policy in respect of its Chief Executive
Officer. The loss of the services of key senior management, or the Company's
inability to attract and retain additional management personnel, could have a
material adverse effect on the Company's business, results of operations or
financial condition. See "Management" and "Certain Relationships and Related
Transactions."
 
RELIANCE ON MAJOR CUSTOMERS
 
   
    A small number of customers account for a significant portion of the
Company's sales. For the six month period ended June 27, 1998, Sebastian
International Inc., WD-40 Co. and Mary Kay Corp. accounted for 13.2%, 8.4% and
8.0%, respectively, of the Company's revenues during this period. The Company
currently sells most of its products to customers pursuant to individually
negotiated purchase orders. The Company generally does not enter into long-term
contracts with its customers, and, therefore, such customers are not obligated
to purchase products from the Company for any specific period, in any specific
quantity or at any specified price, except as may be provided in a particular
purchase order. For the three month period ended March 28, 1998, approximately
52.9% of the Company's net revenues were derived from sales to its top ten
customers. Although the Company believes that its overall relations with
customers are good, there can be no assurance that such customers will continue
to purchase the Company's services, continue with a particular product line
which requires services which the Company offers or contract for the Company's
services in connection with any new or successor product lines. The loss of any
of the Company's major customers or a significant decrease in demand for certain
products sold by such major customers, could have a material adverse effect on
the Company's business, results of operations or financial condition. See
"Business--Customers and Products."
    
 
                                       19
<PAGE>
PRODUCT LIABILITY
 
    The sale of any product can expose the seller of such product to product
liability claims. The Company manufactures products principally for marketers
who sell such products to the public. However, there can be no assurance that
the Company will not be named in a product liability lawsuit involving a product
it produces. Although no material product liability claims have been asserted
against the Company to date, there can be no assurance that such claims will not
arise in the future. The Company now maintains product liability insurance which
provides coverage in the amount of $51 million per occurrence (above a $25,000
per occurrence self-insured retention) and $52 million in the aggregate for all
claims arising in a policy year (above a $250,000 annual aggregate self-insured
retention). A product liability claim that results in a judgment or settlement
in excess of the Company's insurance coverage could have a material adverse
effect on the Company's business, results of operations or financial condition.
See "Business-- Legal Proceedings."
 
CONTROL BY PRINCIPAL STOCKHOLDERS; CHANGE OF CONTROL
 
    GMIP and HarbourVest (through HVP-IV and HVP-V) beneficially own an
aggregate of approximately 80% of the outstanding capital stock of the Company
on a fully-diluted basis. Accordingly, these stockholders have the ability,
acting together, to control fundamental corporate transactions requiring
stockholder approval, including without limitation, approval of merger
transactions involving the Company and sales of all or substantially all of the
Company's assets. There can be no assurance that the interests of GMIP and
HarbourVest (or their respective affiliates) either individually or
collectively, will not conflict with the interests of the holders of the Notes.
See "Management" and "Security Ownership of Certain Beneficial Owners and
Management." In addition, GMIP and HVP-IV (and its affiliates, which would
include HVP-V) are party to the Stockholder Agreement (as defined), pursuant to
which GMIP, HVP-IV and HVP-V, acting together, may force a sale of the Company
and take or block certain other actions. See "Certain Relationships and Related
Transactions--Stockholder Agreement and Registration Rights Agreement."
 
    Upon a Change of Control, each holder of the Notes will have certain rights
to require the Company to repurchase all or a portion of such holder's Notes.
See "Description of Notes." If a Change of Control were to occur, there can be
no assurance that the Company would have sufficient funds to pay the repurchase
price for all Notes tendered by the holders thereof; such failure would result
in an event of default under the Indenture. In addition, a Change of Control
would constitute a default under the Senior Secured Credit Facility (which
agreement would also prohibit payment of the Notes upon a Change of Control) and
may be prohibited or limited by, or create an event of default under, the terms
of other agreements relating to borrowings which either the Company may enter
into from time to time, including other agreements relating to secured
indebtedness or Senior Debt, or the Company's subsidiaries may enter into from
time to time, including other agreements relating to secured indebtedness or
Guarantor Senior Debt.
 
FRAUDULENT TRANSFER CONSIDERATIONS
 
    The obligation of any Guarantor under its guarantee of the Notes may be
subject to review under state or federal fraudulent transfer laws in the event
of the Guarantor's bankruptcy or other financial difficulty. Under those laws,
in a lawsuit by an unpaid creditor or representative of creditors of a
Guarantor, such as a trustee in bankruptcy or the Guarantor as debtor in
possession, if a court were to find that when the Guarantor entered into its
Guarantee, it (a) received less than fair consideration or reasonably equivalent
value therefore, and (b) either (i) was insolvent, (ii) was rendered insolvent,
(iii) was engaged in a business or transaction for which its remaining
unencumbered assets constituted unreasonably small capital, or (iv) intended to
incur or believed that it would incur debts beyond its ability to pay as such
debts matured, the court could avoid such Guarantee and the Guarantee and the
Guarantor's obligations thereunder, and direct the return of any amounts paid
thereunder to the Guarantor or to a
 
                                       20
<PAGE>
fund for the benefit of its creditors. Moreover, regardless of the factors
identified in the foregoing clauses (i) through (iv), the court could avoid a
Guarantee and direct such repayment if it found that the Guarantee was entered
into with actual intent to hinder, delay, or defraud the Guarantor's creditors.
 
    To the extent that a Guarantor's obligation under its Guarantee exceeds the
actual benefit that it receives for the issuance of the Notes, such Guarantor
may be deemed not to have received fair consideration or reasonably equivalent
value for its Guarantee. The Indenture will contain a savings clause that will
generally limit the obligation of each Guarantor under its Guarantee to the
maximum amount (if any) of the obligation that the Guarantor could incur without
that obligation being subject to avoidance as a fraudulent transfer, taking into
account all of the Guarantor's other obligations. There can be no assurance that
the savings clause would permit a Guarantee to survive a fraudulent transfer
attack, even in a reduced amount. If effective, the savings clause may reduce,
perhaps substantially, the obligations of one or more Guarantors under their
respective Guarantees to an amount less than required to pay the Notes in full.
If any Guarantee is avoided or reduced as a result of a fraudulent transfer
attack, holders of the Notes would have to look to the assets of the Company and
any of the remaining Guarantors for payment. There can be no assurance that
there would remain sufficient assets to satisfy the claims of the holders of the
Notes.
 
    The measure of insolvency for purposes of the foregoing will vary depending
on the law of the jurisdiction being applied. Generally, however, an entity
would be considered insolvent if the sum of its debts (including contingent or
unliquidated debts) is greater than all of its property at a fair valuation or
if the present fair salable value of its assets is less than the amount that
will be required to pay its probable liability on its existing debts as they
become absolute and matured.
 
CONSEQUENCES OF FAILURE TO EXCHANGE OLD NOTES
 
    The Old Notes have not been registered under the Securities Act or any other
securities laws of any jurisdiction and, therefore, may not be offered, sold or
otherwise transferred except in compliance with the registration requirements of
the Securities Act and any other applicable securities laws or pursuant to
exemptions from, or in transactions not subject to, those requirements and, in
each case, in compliance with certain other conditions and restrictions. Holders
of Old Notes who do not exchange their Old Notes for New Notes pursuant to the
Exchange Offer will continue to be subject to such restrictions on transfer of
such Old Notes as set forth in the legend thereon. In addition, upon
consummation of the Exchange Offer, holders of Old Notes which remain
outstanding will not be entitled to any rights to have such Old Notes registered
under the Securities Act or to any similar rights under the Registration Rights
Agreement (subject to certain limited exceptions). The Company does not
currently anticipate that it will register or qualify any Old Notes which remain
outstanding after consummation of the Exchange Offer for offer or sale in any
jurisdiction (subject to limited exceptions, if applicable). As a result of
these factors, to the extent that Old Notes are not tendered and accepted in the
Exchange Offer, a holder's ability to sell such Old Notes could be adversely
affected.
 
    The New Notes and any Old Notes which remain outstanding after consummation
of the Exchange Offer will vote together as a single class for purposes of
determining whether holders of the requisite percentage thereof have taken
certain actions or exercised certain rights under the Indenture.
 
    Upon consummation of the Exchange Offer, holders of Old Notes will not be
entitled to any Liquidated Damages or any further registration rights under the
Registration Rights Agreement, except under limited circumstances. See
"Description of Notes--Exchange Offer; Registration Rights."
 
ABSENCE OF PUBLIC MARKET; OPTIONAL REDEMPTION
 
    The Old Notes were issued to, and the Company believes such securities are
currently owned by, a relatively small number of beneficial owners. The Old
Notes have not been registered under the Securities Act and will be subject to
restrictions on transferability if they are not exchanged for the New Notes.
 
                                       21
<PAGE>
Although the New Notes may be resold or otherwise transferred by the holders
(who are not affiliates of the Company) without compliance with the registration
requirements under the Securities Act, they will constitute a new issue of
securities with no established trading market. There can be an assurance that
such a market will develop. In addition, the New Notes will not be listed on any
national securities exchange. The New Notes may trade at a discount from the
initial offering price of the Old Notes, depending upon prevailing interest
rates, the market for similar securities, the Company's operating results and
other factors. The Company has been advised by BT that it currently intends to
make a market in the New Notes, as permitted by applicable laws and regulations;
however, BT is not obligated to do so, and any such market-making activities may
be discontinued at any time without notice. In addition, such market-making
activity may be limited during the pendency of any Shelf Registration Statement.
Therefore, there can be no assurance that an active market for any of the New
Notes will develop, either prior to or after the Company's performance of its
obligations under the Registration Rights Agreement. If an active public market
does not develop, the market price and liquidity of the New Notes may be
adversely affected.
 
    If a public trading market develops for the New Notes, future trading prices
will depend on many factors, including, among other things, prevailing interest
rates, the financial condition of the Company and the Guarantors, and the market
for similar securities. Depending on these and other factors, the New Notes may
trade at a discount.
 
    Historically, the market for non-investment grade debt has been subject to
disruptions that have caused substantial volatility in the prices of such
securities. There can be no assurance that the market for the New Notes will not
be subject to similar disruptions. Any such disruptions may have an adverse
effect on holders of the New Notes.
 
    Notwithstanding the registration of the New Notes in the Exchange Offer,
holders who are "affiliates" (as defined under Rule 405 of the Securities Act)
of the Company may publicly offer for sale or resell the New Notes only in
compliance with the provisions of Rule 144 under the Securities Act.
 
    Each broker-dealer that receives New Notes for its own account in exchange
for Old Notes, where such Old Notes were acquired by such broker-dealer as a
result of market-making activities or other trading activities, must acknowledge
that it will deliver a prospectus in connection with any resale of such New
Notes. See "Plan of Distribution."
 
    In certain circumstances the Company may have the option to redeem some or
all of the Notes, including from proceeds of one or more Equity Offerings. A
partial redemption of the Notes may have the effect of reducing the liquidity of
the unpurchased Notes which could in turn have a negative impact on the market
price thereof. In addition, the Company may elect to exercise such optional
redemption at a time when the market price of the Notes is in excess of the call
price. See "Description of Notes--Redemption."

             UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL DATA
 
    The following unaudited pro forma combined financial data (the "Unaudited
Pro Forma Combined Financial Data") for the the fiscal year ended December 31,
1997 have been derived by the application of pro forma adjustments to the
financial statements of the Company included elsewhere in this Prospectus. The
pro forma statement of operations data give effect to: (i) the Kolmar
Acquisition and the repayment of existing debt of the Company in conjunction
therewith; and (ii) the completion of the Offering and application of the
proceeds therefrom, as if each had occurred at the beginning of the year ended
December 31, 1997 and before changes in accounting principles and extraordinary
items. The adjustments are described in the accompanying notes. The Unaudited
Pro Forma Condensed Combined Financial Data do not purport to represent what the
Company's results of operations actually would have been if those transactions
had been consummated on the dates indicated, or what such results will be for
any future date or for any future period. In addition, the Unaudited Pro Forma
Condensed Combined Financial Data have been prepared by Company management and
are presented for informational purposes only. The pro forma adjustments are
based on management's current assumptions regarding purchase accounting
adjustments for the Kolmar Acquisition based on presently available information
and may change should additional information become available. The Unaudited Pro
Forma Condensed Combined Financial Data should be read in conjunction with
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and the Financial Statements included elsewhere in this Prospectus.
Pro forma statement of operations data for the six months ended June 27, 1998
are not included herein because the adjustments required to give effect to the
Offering and the application of the proceeds therefrom are not considered to be
material to the overall understanding of the financial data presented herein. If
pro forma statement of operations data for the six months ended June 27, 1998
had been presented, interest expense and net income (net of taxes) for the
Company would have increased by $25,000 and decreased by $15,000, respectively.

Reduced salaries and severance costs associated with the termination of certain OSG

    (*) The Company has utilized a forty year useful life based on a number of
       factors including the length of time that Kolmar has been in existence
       and the lack of risk of technological obsolescence associated with its
       products. For ASC and Piedmont, the Company utilized a twenty year useful
       life for amortization of goodwill.
 
       The amount recorded as goodwill has been reviewed for impairment by
       Company management in accordance with its policy on an annual basis. The
       Company evaluates the recoverability of intangible assets based on the
       estimated fair market value of the Company. Based on such evaluation as
       of December 31, 1997, no impairment or write-down existed or is required.

      SELECTED HISTORICAL AND UNAUDITED PRO FORMA COMBINED FINANCIAL DATA
 
    The selected financial data set forth below for the fiscal years ended
December 31, 1993, 1994, 1995, 1996 and 1997 are derived from the audited
financial statements of the Company and its predecessors. Such data for the six
months ended June 29, 1997 and June 27, 1998 are derived from the unaudited
interim financial statements of the Company, which include all adjustments
(consisting only of normal recurring adjustments) which the Company considers
necessary for a fair presentation of the results of operations for the periods
presented. The results for the three month period ended June 27, 1998 are not
necessarily indicative of the results to be expected for the year ending
December 31, 1998 or for any future period. OSG, previously ASHC, was formed to
acquire ASC effective February 14, 1994. OSG had no operations prior to the
acquisition. Consequently, the financial data set forth below for the fiscal
year ended December 31, 1994 includes the audited results of OSG for the period
from inception, February 15, 1994 to December 31, 1994 and the unaudited
balances of ASC for the period from January 1, 1994 to February 14, 1994.
Amounts in 1993 reflect the operating results and financial position of ASC,
prior to its acquisition by OSG.
 
    The selected financial data for Piedmont set forth below for the fiscal
years ended September 30, 1993, 1994, 1995 and 1996 are derived from the audited
financial statements of Piedmont. Such data for Kolmar for the fiscal years
ended December 31, 1995, 1996 and 1997 are derived from audited combined
financial statements. Kolmar financial data for the years ended December 31,
1993 and 1994 are derived from Kolmar's unaudited financial statements. The
unaudited financial statements for the years ended December 31, 1993 and 1994
include all adjustments (consisting only of normal recurring adjustments) which
management of Kolmar considers necessary for a fair presentation of the
financial data for the periods presented.
 
    The selected unaudited pro forma combined financial data of the Company for
the fiscal year ended December 31, 1997 are derived from the Unaudited Pro Forma
Condensed Combined Financial Data included elsewhere in this Prospectus. Such
data give effect to (i) the Kolmar Acquisition and the repayment of existing
debt of the Company in conjunction therewith; and (ii) the completion of the
Offering and application of the proceeds therefrom, as if each had occurred at
the beginning of the year ended December 31, 1997 and before changes in
accounting principles and extraordinary items. The related pro forma balance
sheet data give effect to (i) and (ii) as if each had occurred on December 31,
1997.
 
    The following information should be read in conjunction with the
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and the Financial Statements included elsewhere in this Prospectus.

  NOTES TO SELECTED HISTORICAL AND UNAUDITED PRO FORMA COMBINED FINANCIAL DATA
 
(a) The Piedmont and Kolmar acquisitions were effective on September 30, 1996
    and January 1, 1998, respectively. Consequently, the Company's Statements of
    Operations Data and Other Data for the year ended December 31, 1997 and for
    the six months ended June 27, 1998 (which includes the acquired operations
    for the entire period) are not directly comparable to the Statements of
    Operations Data and Other Data for the comparable periods in prior years.
    Additionally, the results of operations for the fiscal year ended December
    31, 1996 include the acquired operations for the three-month period
    subsequent to the Piedmont acquisition.
 
(b) Net income of OSG for the fiscal year ended December 31, 1993 reflects $5.5
    million of owners' bonus compensation prior to the acquisition of ASC by the
    Company. Net loss of OSG for the fiscal year ended December 31, 1996
    includes a $7.0 million charge associated with the cumulative effect of a
    change in accounting principle. Net loss for the year ended December 31,
    1997 and for the six months ended June 27, 1998 includes $1.1 million and
    $2.1 million of extraordinary items, respectively, net of tax, associated
    with charges for early retirement of debt.
 
(c) Adjusted EBITDA represents the sum of income from operations and
    depreciation and amortization. For the fiscal year ended December 31, 1993,
    the predecessor company to OSG paid its owners a bonus of $5.5 million. Such
    payment has not been reflected in adjusted EBITDA. In addition, adjusted
    EBITDA for the fiscal year ended December 31, 1993 excludes the loss from
    operations from a discontinued operation totaling $100,000. The assets of
    such operation were not purchased by OSG. Adjusted EBITDA for Kolmar
    excludes a write-off of goodwill of $12,963,000 and a charge for
    restructuring costs of $3,935,000 for the fiscal year ended December 31,
    1993 and a $24,100,000 write-down of assets for the fiscal year ended
    December 31, 1994.
 
    Adjusted EBITDA is not intended to represent cash flows from operations as
    defined by GAAP and should not be considered as an alternative to net income
    as an indicator of the Company's operating performance or to cash flows as a
    measure of liquidity. Adjusted EBITDA is included herein as it is a basis
    upon which the Company assesses its financial performance and its ability to
    service indebtedness. Adjusted EBITDA as calculated herein differs from the
    definition of the term "Consolidated EBITDA" used in the Indenture under
    which the New Notes are to be issued. See "Description of Notes--Certain
    Definitions."
 
(d) Piedmont and Kolmar use 52-53 week fiscal years. For presentation purposes,
    Piedmont's fiscal year has been reflected as if it ended on September 30.
    Kolmar's fiscal year has been reflected as if it ended on December 31.
 
(e) Net loss for Kolmar for the fiscal year ended December 31, 1993 reflects
    charges for restructuring costs of $3,935,000 and a write-off of $12,963,000
    of goodwill. Net loss for Kolmar for the fiscal year ended December 31, 1994
    reflects a $24,100,000 write-down of assets.
 
(f) See "Unaudited Pro Forma Condensed Combined Financial Data" for information
    related to pro forma adjustments.
 
(g) Unaudited pro forma combined interest expense includes amortization of
    deferred financing costs of $1.1 million for the fiscal year ended December
    31, 1997.
 
(h) Unaudited pro forma combined net income is computed excluding the effects of
    extraordinary items and the cumulative effects of a change in accounting
    principle.
 
(i) Unaudited pro forma combined adjusted EBITDA represents the sum of income
    from operations and depreciation and amortization and excludes non-recurring
    charges, consisting primarily of salary expenses of $1.1 million for the
    termination of certain OSG management concurrent with the Kolmar Acquisition
    and broken deal costs of $138,000 for the fiscal year ended December 31,
    1997.
 
(j) The ratio of earnings to fixed charges for OSG was less than 1 to 1 and
    earnings were insufficient to cover fixed charges by $228,000 during the six
    month period ended June 29, 1997.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
GENERAL
 
    OSG, through its operating subsidiaries, ASC, Piedmont and Kolmar, is a
full-service contract manufacturer and packager of consumer products for
marketers in the health and beauty aid, household and automotive consumer
product markets. The Company manufactures and packages a broad range of products
including color cosmetics (such as lipstick, face powders and eye shadow),
aerosols (such as hair spray, shaving cream and gel and lubricants) and creams,
lotions and liquids (such as skin care products, shampoo, pump hair spray and
lighter fluid). Management believes OSG is the largest independent contract
manufacturer and packager of color cosmetics, high-end salon aerosol hair care
products and shaving creams and gels in North America.
 
   
    The Company typically charges a per-unit fee which varies depending on: (i)
the type of product, (ii) the type of services provided (filling only versus
product development, formulation, materials procurement, etc.), (iii) the
container size and order quantity, and (iv) the complexity of the manufacturing
and packaging process. In many cases, the Company purchases the raw and
packaging materials on behalf of its customers. In such instances, the Company
passes the costs of such materials on to its customers and charges a handling
fee in addition to the fill fee. Typically the Company's gross margin on
purchases of raw materials on behalf of its clients is lower than its gross
margin on filled goods. For the years December 31, 1995, December 31, 1996 and
December 31, 1997, and for the six months ended June 29, 1997 and June 27, 1998,
the Company purchased approximately $76.7 million, $105.2 million, $112.9
million, $55.3 million and $62.4 million of raw materials for its customers. The
percentage of materials purchased directly by customers versus purchased by the
Company on behalf of customers may have an impact on total revenues and cost of
goods sold.
    
 
    The predecessor to OSG, ASHC, was organized on February 14, 1994 to acquire
ASC from its founders. On September 30, 1996, GMIP, HVP-IV and certain members
of management independently acquired Piedmont in a purchase of stock from its
founder. On June 30, 1997, Piedmont's holding company, ACHC, was merged with and
into ASHC (the "Merger"). The Merger was accounted for similar to a pooling of
interests. Such accounting treatment is in accordance with Interpretation No. 39
of APB Opinion 16, appropriate for entities under common control and results in
the combined assets and liabilities for both entities being recorded at their
historical cost. ASHC's name was changed to OSG. As a result, the Company's
historical statements of operations for the period from September 30, 1996 (the
time of the GMIP and HVP-IV investments) through June 30, 1997 were restated to
include the statements of operations of Piedmont. Because of the accounting
structure of the acquisition of Piedmont, the Company's financial results for
the year ended December 31, 1996 include only three months of Piedmont's
operations. Similarly, the financial results for the nine months ended September
30, 1996 include only the operating results of ASC. The financial results for
the fiscal year ended December 31, 1997 and the six months ended June 29, 1997
and June 27, 1998 include the results of both Piedmont and ASC.
 
    The Company's results of operations for the periods presented herein are not
readily comparable due to the acquisition of Piedmont as of September 30, 1996
and due to the acquisition of Kolmar as of January 1, 1998. The results of
operations for the fiscal years 1995 through 1997 for OSG and Kolmar are
discussed separately below. The financial results for the six month period ended
June 27, 1998 includes the results of ASC, Piedmont and Kolmar.

SIX MONTHS ENDED JUNE 27, 1998 VERSUS SIX MONTHS ENDED JUNE 29, 1997
 
    NET REVENUES.  Net revenues increased $63.2 million, or 122.1% to $115
million for the six months ended June 27, 1998 from $51.8 million for the six
months ended June 29, 1997. The increase was primarily attributable to the
acquisition of Kolmar effective January 1, 1998, which accounted for $48.9
million or 77.4% of the increase in net revenues. Without the acquisition of
Kolmar, net revenues increased approximately $14.3 million or 27.6%, due
primarily to an increase in net revenues from aerosol products due to a
combination of a 23.3% increase in volume and a continuing shift at ASC towards
providing more raw materials for its customers.
 
    COST OF GOODS SOLD.  Cost of goods sold increased $52.8 million, or 118.9%
to $97.2 million for the six months ended June 27, 1998 from $44.4 million for
the six months ended June 29, 1997. The increase was primarily attributable to
the acquisition of Kolmar, which accounted for $37.8 million or 71.6% of the
increase in cost of goods sold. Without the acquisition of Kolmar, cost of goods
sold increased approximately $15 million or 33.8%, due primarily to an increase
in the volume of aerosol products sold, as well as increases in the minimum wage
in California and a continuing shift at ASC towards purchasing more raw
materials for its customers. As a percentage of net revenues, cost of goods sold
declined to 84.6% for the six months ended June 27, 1998 from 85.8% for the six
months ended June 29, 1997. This was primarily attributable to the fact that
Kolmar's cost of goods sold as a percentage of net revenue was lower than ASC's
and Piedmont's, since ASC and Piedmont purchase raw materials for a higher
percentage of their customers. This decline was partially offset by an increase
in ASC's cost of goods as a result of an increase in the minimum wage in
California (September 1997 and March 1998) as well as a continuing shift toward
purchasing more raw material for it's customers.
 
    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, general and
administrative expenses ("SG&A") increased $5.2 million or 99.9% to $10.4
million for the six months ended June 27, 1998 from $5.2 million for the six
months ended June 29, 1997. The increase was primarily attributable to the
acquisition of Kolmar, which accounted for $5.0 million, or 95.4% of the
increase in SG&A. As a percentage of net revenues, SG&A decreased to 9.1% for
the six months ended June 27, 1998 from 10.1% for the six months ended June 29,
1997.
 
                                       33
<PAGE>
    INTEREST EXPENSE.  Interest expense increased $3.7 million, or 158% to $6.1
million for the six months ended June 27, 1998 from $2.4 million for the six
months ended June 29, 1997. The increase was primarily attributable to the
increase of indebtedness to finance the acquisition of Kolmar.
 
    EXTRAORDINARY ITEM.  As a result of the January 1998 refinancing in
conjunction with the acquisition of Kolmar and the March 3, 1998 refinancing of
all indebtedness then outstanding under the Senior Secured Credit Facility and
the Subordinated Bridge Facility, with $105.0 million of Notes, the Company
wrote off deferred financing charges of $2.2 million, net of $1.4 million of
taxes, related to the prior indebtedness.
 
    EBITDA.  EBITDA increased $6.6 million, or 144.1% to $11.2 million for the
six months ended June 27, 1998 from $4.6 million for the six months ended June
29, 1997.
 
    CAPITAL EXPENDITURES.  On April 30, 1998, one of the company's subsidiaries
entered into an "Asset Purchase Agreement" with a competitor to acquire certain
packaging equipment for $0.6 million. In addition to this purchase, capital
expenditures for the six months ended June 27, 1998 were $0.9 million and
consisted primarily of maintenance oriented projects, new customer requirements
and various cost savings expenditures.
 
FISCAL YEAR ENDED DECEMBER 31, 1997 VERSUS FISCAL YEAR ENDED DECEMBER 31, 1996
 
    NET REVENUES.   Net revenues increased $30.5 million, or 38.2% to $110.3
million for the year ended December 31, 1997 from $79.8 million for the year
ended December 31, 1996. The increase was primarily attributable to the
acquisition of Piedmont on September 30, 1996, which accounted for $36.1 million
or 118.4% of the increase in net revenues. Without the acquisition of Piedmont,
net revenues decreased approximately $5.7 million, or 7.1% due to a decline in
net revenues from household products, which was partially offset by an increase
in personal care products.
 
    COST OF GOODS SOLD.  Cost of goods sold increased $26.5 million, or 38.6% to
$95.2 million for the year ended December 31, 1997 from $68.7 million for the
year ended December 31, 1996. The increase was primarily attributable to the
acquisition of Piedmont, which accounted for $30.9 million, or 116.6 % of the
increase in cost of goods sold. Without the acquisition of Piedmont, cost of
goods sold decreased approximately $4.2 million or 6.1% primarily as a result of
a decline in net revenues at ASC. As a percentage of net revenues, cost of goods
sold increased to 86.3% for the year ended December 31, 1997 from 86.1% for the
year ended December 31, 1996. This was primarily attributable to the fact that
ASC's cost of goods increased as a result of an increase in the cost of labor
due to the minimum wage increase in September 1996 (Federal) and March 1997
(California), and a continuing shift toward purchasing more raw material for its
customers, which was partially offset by the fact that Piedmont's cost of goods
sold as a percentage of net revenues was lower than ASC's given ASC purchased
raw materials for a higher percentage of customers.
 
    SG&A.  SG&A increased $4.8 million or 80% to $10.8 million for the year
ended December 31, 1997 from $6.0 million for the year ended December 31, 1997.
The increase was primarily attributable to the acquisition of Piedmont, which
accounted for $4.4 million, or 91.7% of the increase in SG&A. As a percentage of
net revenues, SG&A increased to 9.8% for the year ended December 31, 1997 from
7.5% for the year ended December 31, 1996. In addition to the acquisition of
Piedmont, the increase in SG&A was attributable to costs associated with staff
additions in senior management and research and development and an upgrade in
the Company's computer system, as well as expenses related to an unsuccessful
acquisition bid.
 
    INTEREST EXPENSE.  Interest expense increased $0.6 million, or 16.6% to $4.2
million for the year ended December 31, 1997 from $3.6 million for the year
ended December 31, 1996. The increase was partially attributable to the
acquisition of Piedmont, which accounted for $0.2 million, or 33.3 % of the
increase, as well as additional borrowing to meet increased working capital
requirements.

    EXTRAORDINARY ITEM.  On June 30, 1997, the Company refinanced its credit
agreement concurrent with the formation of OSG and the merger. As a result of
this refinancing, the Company wrote off deferred financing charges of $1.1
million, net of $0.6 million of taxes, related to the prior indebtedness.
 
    CUMULATIVE EFFECT OF CHANGE IN ACCOUNTING PRINCIPLE.  During fiscal 1996,
the Company changed its accounting policy for evaluating the recoverability of
intangible assets. Previously, the Company determined the recoverability of
intangible assets by considering estimated future operating income of the
Company on an undiscounted cash flow basis. Under its new policy, the Company
evaluates the recoverability of intangible assets based on the estimated fair
market value of the Company. The cumulative effect of the change in accounting
policy has resulted in a write down of goodwill associated with the acquisition
of ASC of $7.0 million.
 
    ADJUSTED EBITDA.  EBITDA increased $1.0 million, or 13.2% to $8.6 million
for the year ended December 31, 1997 from $7.6 million for the year ended
December 31, 1996. The increase was primarily attributable to the acquisition of
Piedmont, which accounted for $2.8 million of the increase in EBITDA, which was
offset by a decline in volume attributable to household products, costs
attributable to staff additions in senior management and an upgrade in the
Company's computer systems as well as expenses related to an unsuccessful
acquisition bid.
 
    CAPITAL EXPENDITURES.  Capital expenditures for the year ended December 31,
1997 were $1.5 million and consisted primarily of maintenance oriented projects,
new customer requirements and various cost savings expenditures.
 
FISCAL YEAR ENDED DECEMBER 31, 1996 VERSUS FISCAL YEAR ENDED DECEMBER 31, 1995
 
    NET REVENUES.  Net revenues increased $19.2 million, or 31.7% to $79.8
million for the year ended December 31, 1996 from $60.6 million for the year
ended December 31, 1995. The acquisition of Piedmont accounted for $7.5 million,
or 39.1% of the increase in net revenues. Without the acquisition of Piedmont,
net revenues increased approximately $11.7 million, or 19.3%, due to a strong
market for personal care and household products. This included new product
launches of premium hair care products for several key customers in the high-end
salon market.
 
    COST OF GOODS SOLD.  Cost of goods sold increased $16.3 million, or 31.1% to
$68.7 million for the year ended December 31, 1996 from $52.4 million for the
year ended December 31, 1995. The acquisition of Piedmont accounted for $6.3
million, or 38.7% of the increase in cost of goods sold. As a percentage of net
revenues, cost of goods sold declined from 86.4% to 86.1%. This is primarily
attributable to the fact that Piedmont's cost of goods sold margin is lower than
ASC's, since ASC purchases raw materials for a higher percentage of its
customers. Excluding the effects of the acquisition of Piedmont, cost of goods
sold as a percentage of net revenues remained essentially unchanged at 86.3% for
the year ended December 31, 1996 compared to 86.4% for the year ended December
31, 1995.
 
    SG&A.  SG&A increased $1.4 million, or 30.4% to $6.0 million for the year
ended December 31, 1996 from $4.6 million for the year ended December 31, 1995.
The increase was primarily attributable to the acquisition of Piedmont, which
accounted for $1.1 million, or 78.6% of the increase in SG&A. As a percentage of
net revenues, SG&A decreased to 7.5% for the year ended December 31, 1996 from
7.6% for the year ended December 31, 1995. Excluding the acquisition of
Piedmont, SG&A as a percentage of net revenues declined to 6.1% for the year
ended December 31, 1996 from 7.6% for the year ended December 31, 1995. The
decline in SG&A as a percentage of net revenues was largely attributable to
economies of scale realized with the significant increase in net revenues.
 
    INTEREST EXPENSE.  Interest expense remained essentially unchanged at $3.6
million for the year ended December 31, 1996 despite a $0.2 million increase due
to the acquisition of Piedmont which was offset by a decline in interest expense
attributable to lower average borrowings.

FISCAL YEARS ENDED DECEMBER 31, 1997 VERSUS FISCAL YEARS ENDED DECEMBER 31, 1996
 
    NET REVENUES.  Net revenues decreased $0.2 million, or 0.2% to $103.1
million for the year ended December 31, 1997 from $103.3 million for the year
ended December 31, 1996. The decrease in net revenues was a result of certain
customers taking business in-house which was partially offset by new business
with existing and new customers as well as an increase in the percentage of
customers for whom the Company purchased raw materials and packaging components.
 
    COST OF GOODS SOLD.  Cost of goods sold increased $2.9 million, or 3.5% to
$86.2 million for the year ended December 31, 1997 from $83.3 million for the
year ended December 31, 1996. As a percentage of net revenues, cost of goods
sold increased to 83.5% from 80.6%. The increase was primarily due to a change
in the product mix sold and to an increase in the percentage of customers for
whom Kolmar purchased raw materials and packaging components.
 
    SG&A.  As a result of management's continued effort to reduce costs, SG&A
decreased $2.1 million or 20.6% to $8.1 million for the year ended December 31,
1997 from $10.2 million for the year ended December 31, 1996. As a percentage of
net revenues, SG&A decreased to 7.9% for the year ended December 31, 1997 from
9.8% for the year ended December 31, 1996. The improvement was due in large part
to a more cost effective worker's compensation program adopted in 1997, as well
as staff reductions and other cost reductions.
 
                                       36
<PAGE>
    INTEREST EXPENSE.  Interest expense increased $0.5 million, or 13.5% to $4.2
million for the year ended December 31, 1997 from $3.7 million for the year
ended December 31, 1996. Such interest expense was related to obligations owed
to Kolmar's former owner, CCL.
 
    ADJUSTED EBITDA.  EBITDA decreased $0.6 million, or 4.9% to $11.6 million
for the year ended
December 31, 1997 from $12.2 million for the year ended December 31, 1996.
 
    CAPITAL EXPENDITURES.  Capital expenditures for the year ended December 31,
1997 were $2.9 million and consisted primarily of maintenance oriented projects,
new customer requirements, cost reduction expenditures, information systems and
environmental safety and regulation expenditures.
 
FISCAL YEAR ENDED DECEMBER 31, 1996 VERSUS FISCAL YEAR ENDED DECEMBER 30, 1995
 
    NET REVENUES.  Net revenues increased $29.0 million, or 39.0% to $103.3
million for the year ended December 31, 1996 from $74.3 million for the year
ended December 30, 1995. The acquisition of Imperial Cosmetics Services
("Imperial") on January 4, 1996 accounted for $6.9 million, or 23.8% of the
increase in net revenues. Excluding the acquisition of Imperial, net revenues
increased approximately $22.1 million, or 29.7%, due to a strong market for
color cosmetic, particularly lipsticks, and skin care products. In addition, net
revenues increased due to a higher percentage of customers for whom Kolmar
purchased all raw and packaging materials.
 
    COST OF GOODS SOLD.  Cost of goods sold increased $23.0 million, or 38.1% to
$83.3 million for the year ended December 31, 1996 from $60.3 million for the
year ended December 30, 1995. The acquisition of Imperial accounted for $5.3
million, or 23.0% of the increase in cost of goods sold. As a percentage of net
revenues, cost of goods sold declined from 81.2% to 80.6%. This was primarily
due to economies of scale from the increase in net revenues as well as an
improvement in product mix. Excluding the acquisition of Imperial, cost of goods
sold as a percentage of net revenues improved to 80.9% for the year ended
December 31, 1996 from 81.2% for the year ended December 30, 1995.
 
    SG&A.  SG&A increased $1.0 million, or 10.9% to $10.2 million for the year
ended December 31, 1996 from $9.2 million for the year ended December 30, 1995.
The increase was entirely attributable to the acquisition of Imperial, which
accounted for $1.0 million, or 100% of the increase in SG&A. As a percentage of
net revenues, SG&A decreased to 9.9% for the year ended December 31, 1996 from
12.4% for the year ended December 30, 1995. Excluding the acquisition of
Imperial, SG&A as a percentage of net revenues declined to 9.5% for the year
ended December 31, 1996 from 12.4% for the year ended December 30, 1995. The
decline in SG&A as a percentage of net revenues was largely attributable to
economies of scale realized with the increase in net revenues, as well as a
continuation of cost reduction efforts.
 
    INTEREST EXPENSE.  Interest expense was $3.7 million for the year ended
December 31, 1996, versus $3.1 million for the year ended December 31, 1995. The
increase was due to higher borrowings from CCL for working capital and capital
expenditures.
 
    ADJUSTED EBITDA.  EBITDA increased $5.3 million, or 76.8% to $12.2 million
for the year ended December 31, 1996 from $6.9 million for the year ended
December 31, 1995. The acquisition of Imperial accounted for approximately $1.1
million, or 20.8% of the increase in EBITDA.
 
    CAPITAL EXPENDITURES.  Capital expenditures for the year ended December 31,
1996 were $3.8 million and consisted primarily of new customer requirements,
maintenance oriented projects, cost reduction expenditures, information systems
and environmental, safety and regulation expenditures.

LIQUIDITY AND CAPITAL RESOURCES
 
    As of June 27, 1998, OSG had cash and short-term investments of $4.4 million
and long-term debt of $106.8 million. The primary sources of cash were from
financing and investing activities. Cash (used in) provided by operations was
$(5.5) million and $5.0 million for the six months ended June 27, 1998 and June
29, 1997, respectively. Principal uses of cash were for capital expenditures and
debt repayment. Net repayments under the Company's working capital facilities
were $8.9 million and $3.2 million for the six months ended June 27, 1998 and
June 29, 1997, respectively.
 
    As of January 1, 1998, OSG consummated the Kolmar Acquisition. The purchase
price for the Kolmar Acquisition was $78.0 million, subject to certain
post-closing adjustments. In conjunction with the Kolmar Acquisition, the
Company refinanced all of its existing indebtedness totaling $36.2 million. The
purchase price and refinanced indebtedness, plus $7.4 million of fees and
expenses, was financed through $30.0 million of borrowings under the Senior
Secured Credit Facility, $70.0 million of borrowings under the Subordinated
Bridge Facility and the issuance of $20.9 million of Common Stock to existing
stockholders of the Company.
 
    On March 3, 1998, OSG refinanced all of its existing indebtedness totaling
$99.8 million. The refinanced indebtedness, plus $3.3 million of fees and
expenses, was financed through the issuance of $105.0 million of the Notes.
 
    As a result of the refinancing of existing indebtedness and the indebtedness
incurred to consummate the Kolmar Acquisition, the Company is highly leveraged.
As of June 27, 1998, the Company's indebtedness was $106.8 million of which
$105.0 million bears an interest rate of 10 7/8% per annum with the balance of
$1.8 million indebtedness bearing interest under the terms of the Senior Secured
Credit Facility with an affiliate of Bankers Trust ("BTCO"). As of June 27,
1998, stockholder's equity was $12.8 million and the Company's subsidiaries had
$52.1 million of availability under the Senior Secured Credit Facility. The
Senior Secured Credit Facility bears interest at a floating rate based on (1)
the Prime Lending Rate (defined as the rate which BTCO announces as its prime
lending rate from time to time), plus 0.75% or (2) the Eurodollar Rate (defined
as the rate of the offered quotation, if any, to first class banks in the
Eurodollar market by BTCO for U.S. dollar deposits) for one, two, three or six
months, in each case plus 2.25%. The obligations of the Company's subsidiaries
under the Senior Secured Credit Facility are secured by a security interest in
substantially all of their assets, and the Company's obligations under its
guarantee of the Senior Secured Credit Facility are secured by substantially all
of its assets. The terms of the Notes and the Senior Secured Credit Facility
have restrictive covenants that restrict the Company's ability to pay dividends,
sell certain assets, and incur additional borrowings. Furthermore, the Company
is required to maintain certain financial ratios and satisfy financial condition
tests. The Company's ability to pay principal and interest on its indebtedness,
will depend upon the future operating performance of its subsidiaries and will
require a substantial portion of the Company's cash flow from operations. For
the six months ended June 27, 1998, the Company's ratio of earnings to fixed
charges was 1.18.
 
   
    In conjunction with the Kolmar Acquisition and the issuance of the Notes,
the Company wrote off $3.6 in deferred financing costs associated with prior
financings.
    
 
    Pursuant to the Management Services Agreement (as defined), the Company paid
G+MG $800,000 upon closing of the Kolmar Acquisition and will pay G+MG, in
exchange for management services, (i) an annual fee of $350,000, which is
subject to adjustment, and (ii) up to 2% of the total consideration received or
paid in various transactions. The Company is also a party to the HarbourVest
Agreement (as defined), pursuant to which the Company will pay HarbourVest, in
exchange for financial and business advisory services, (i) an annual fee of
$115,000 and (ii) 1/3 of the fee, under certain conditions, received by G+MG
under its Management Services Agreement with the Company. See "Certain
Relationships and Related Transactions--Management Services Agreement."

    As part of the acquisition of Kolmar, the Company became responsible for an
existing Kolmar benefit plan. Although the Company reserves the right to amend
such benefit plan, the Company is evaluating such benefit plans status and
whether to extend it to additional participants.
 
    The Company anticipates that its primary uses of working capital in future
periods will be to service it's 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 believes that cash on hand, cash flow from operations and
available borrowings under its Senior Secured Credit Facility, will be
sufficient to meet the Company's presently anticipated working capital and
capital expenditure needs through fiscal 1999.
    
 
    The Company's capital expenditures are expected to decline slightly from
historical levels as a result of the significant historical spending on
information system upgrades and major cost-saving programs. The Company's
capital expenditures will be primarily for new customer requirements,
maintenance, cost-saving projects, environmental, safety and regulatory
expenditures. As of June 27, 1998 the Company had $0.5 million of commitments
for capital expenditures.
 
    The Company has established a Year 2000 Project team that is currently
reviewing the internal and external readiness of its computer systems, business
practices, suppliers and customers for handling Year 2000 issues. These issues
involve systems that are date sensitive and may not be able to distinguish 20th
century dates from 21st century dates resulting in miscalculations and software
failures. The Company has developed plans to address internal system
modifications required to minimize the potential problems by December 31, 1999.
Currently in the initial phase, the Company is in the process of identifying all
hardware and software systems within the Company. Included in this group are
systems used in the information technology group as well as non-information
technology systems, such as production equipment that is date sensitive.
Additionally, the Company is in the process of contacting all of the its key
external business partners to determine their extent and plans for Year 2000
compliance.
 
    Based on analysis completed to date, management believes its current staff
will be sufficient to address the Year 2000 issues and that the staff time
required to address such issues should not have an adverse effect on other
projects. Also, the Company recognizes the need for a contingency plan for
continued operations in the case of business interruption and intends to
formulate such a plan in the near future. Management currently estimates that
its costs related to the Year 2000 issue will be approximately $150,000.
Management believes such costs will not have a material effect on its results of
operations or financial condition. However, there can be no assurance that there
will not be a delay in, or increased costs associated with, the implementation
of the necessary systems and changes to address the Year 2000 issues, and the
Company's inability to implement such systems and changes could have an adverse
effect on future results of operations. In addition, the failure of certain of
the Company's significant customers or vendors to appropriately address the Year
2000 issue in a timely manner could have a material adverse effect on the
Company.

will give oral or written notice of any extension, amendment, non-acceptance or
termination to the Holders of the Notes as promptly as practicable, such notice
in the case of any extension to be issued by means of a press release or other
public announcement no later than 9:00 a.m., New York City time, on the next
business day after the previously scheduled Expiration Date.
 
PROCEDURES FOR TENDERING OLD NOTES
 
    The tender to the Company of Old Notes by a Holder thereof as set forth
below and the acceptance thereof by the Company will constitute a binding
agreement between the tendering Holder and the Company upon the terms and
subject to the conditions set forth in this Prospectus and in the accompanying
Letter of Transmittal. Except as set forth below, a Holder who wishes to tender
Old Notes for exchange pursuant to the Exchange Offer must transmit a properly
completed and duly executed Letter of Transmittal, including all other documents
required by such Letter of Transmittal or (in the case of a book-entry transfer)
an Agent's Message in lieu of such Letter of Transmittal, to the Exchange Agent
at the address set forth below under "Exchange Agent" on or prior to the
Expiration Date. In addition, either (i) certificates for such Old Notes must be
received by the Exchange Agent along with the Letter of Transmittal, or (ii) a
timely confirmation of a book-entry transfer (a "Book-Entry Confirmation") of
such Old Notes, if such procedure is available, into the Exchange Agent's
account at DTC (the "Book-Entry Transfer Facility") pursuant to the procedure
for book-entry transfer described below, must be received by the Exchange Agent
prior to the Expiration Date with the Letter of Transmittal or an Agent's
Message in lieu of such Letter of Transmittal, or (iii) the Holder must comply
with the guaranteed delivery procedures described below. The term "Agent's
Message" means a message, transmitted by the Book-Entry Transfer Facility to and
received by the Exchange Agent and forming a part of a Book-Entry Confirmation,
which states that the Book-Entry Transfer Facility has received an express
acknowledgment from the tendering participant, which acknowledgment states that
such participant has received and agrees to be bound by the Letter of
Transmittal and that the Company may enforce such Letter of Transmittal against
such participant. THE METHOD OF DELIVERY OF OLD NOTES, LETTERS OF TRANSMITTAL
AND ALL OTHER REQUIRED DOCUMENTS IS AT THE ELECTION AND RISK OF THE HOLDERS.
 
                                       40
<PAGE>
IF SUCH DELIVERY IS BY MAIL, IT IS RECOMMENDED THAT REGISTERED MAIL, PROPERLY
INSURED, WITH RETURN RECEIPT REQUESTED, BE USED. IN ALL CASES, SUFFICIENT TIME
SHOULD BE ALLOWED TO ASSURE TIMELY DELIVERY. NO LETTERS OF TRANSMITTAL OR OLD
NOTES SHOULD BE SENT TO THE COMPANY.
 
    Signatures on a Letter of Transmittal or a notice of withdrawal, as the case
may be, must be guaranteed unless the Old Notes surrendered for exchange
pursuant thereto are tendered (i) by a Holder of the Old Notes who has not
completed the box entitled "Special Issuance Instructions" or "Special Delivery
Instructions" on the Letter of Transmittal or (ii) for the account of an
Eligible Institution (as defined below). In the event that signatures on a
Letter of Transmittal or a notice of withdrawal, as the case may be, are
required to be guaranteed, such guarantees must be by a firm which is a member
of a registered national securities exchange or a member of the National
Association of Securities Dealers, Inc. or by a commercial bank or trust company
having an office or correspondent in the United States or an "eligible guarantor
institution" within the meaning of Rule 17Ad-15 under the Exchange Act which is
a member of one of the recognized signature guarantee programs identified in the
Letter of Transmittal (an, "Eligible Institution"). If Old Notes are registered
in the name of a person other than a signer of the Letter of Transmittal, the
Old Notes surrendered for exchange must be endorsed by, or be accompanied by a
written instrument or instruments of transfer or exchange, in satisfactory form
as determined by the Company in its sole discretion, duly executed by the
registered owner with the signature thereon guaranteed by an Eligible
Institution.
 
    All questions as to the validity, form, eligibility (including time of
receipt) and acceptance of Old Notes tendered for exchange will be determined by
the Company in its sole discretion, which determination shall be final and
binding. The Company reserves the absolute right to reject any and all tenders
of any particular Old Notes not properly tendered or to not accept any
particular Old Notes which acceptance might, in the judgment of the Company or
their counsel, be unlawful. The Company also reserves the absolute right to
waive any defects or irregularities or conditions of the Exchange Offer as to
any particular Old Notes either before or after the Expiration Date (including
the right to waive the ineligibility of any Holder who seeks to tender Old Notes
in the Exchange Offer). The interpretation of the terms and conditions of the
Exchange Offer as to any particular Old Note either before or after the
Expiration Date (including the Letter of Transmittal and the instructions
thereto) by the Company shall be final and binding on all parties. Unless
waived, any defects or irregularities in connection with tenders of Old Notes
for exchange must be cured within such reasonable period of time as the Company
shall determine. Neither the Company, the Exchange Agent nor any other person
shall be under any duty to give notification of any defect or irregularity with
respect to any tender of Old Notes for exchange, nor shall any of them incur any
liability for failure to give such notification.
 
    If the Letter of Transmittal is signed by a person or persons other than the
registered Holder or Holders of Old Notes, such Old Notes must be endorsed or
accompanied by powers of attorney, in either case signed exactly as the name or
names of the registered Holder or Holders that appear on the Old Notes.
 
    If the Letter of Transmittal or any Old Notes or powers of attorneys are
signed by trustees, executors, administrators, guardians, attorneys-in-fact,
officers of corporations or others acting in a fiduciary or representative
capacity, such persons should so indicate when signing, and, unless waived by
the Company, proper evidence satisfactory to the Company of their authority to
so act must be submitted with the Letter of Transmittal.
 
    By tendering, each Holder will represent to the Company that, among other
things, the New Notes acquired pursuant to the Exchange Offer are being obtained
in the ordinary course of business of the person receiving such New Notes,
whether or not such person is the Holder and that neither the Holder nor such
other person has any arrangement or understanding with any person to participate
in the distribution of the New Notes. If any Holder or any such other person is
an "affiliate", as defined under
 
                                       41
<PAGE>
Rule 405 of the Securities Act, of the Company and is engaged in or intends to
engage in or has an arrangement or understanding with any person to participate
in a distribution of such New Notes to be acquired pursuant to the Exchange
Offer, then such Holder or any such other person (i) could not rely on the
applicable interpretations of the staff of the Commission and (ii) must comply
with the registration and prospectus delivery requirements of the Securities Act
in connection with any resale transaction. Each broker-dealer that receives New
Notes for its own account in exchange for Old Notes, where such Old Notes were
acquired by such broker-dealer as a result of market-making activities or other
trading activities, must acknowledge that it will deliver this Prospectus in
connection with any resale of such New Notes. See "Plan of Distribution." The
Letter of Transmittal states that by so acknowledging and by delivering this
Prospectus, a broker-dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act.
 
ACCEPTANCE OF OLD NOTES FOR EXCHANGE; DELIVERY OF NEW NOTES
 
    Upon satisfaction of all of the conditions to the Exchange Offer, the
Company will accept, promptly after the Expiration Date, all Old Notes properly
tendered and will issue the New Notes promptly after acceptance of the Old
Notes. See "--Certain Conditions to the Exchange Offer" below. For purposes of
the Exchange Offer, the Company shall be deemed to have accepted properly
tendered Old Notes for exchange when, as and if the Company has given oral
(promptly confirmed in writing) or written notice thereof to the Exchange Agent.
 
    For each Old Note accepted for exchange, the Holder of such Old Note will
receive a New Note having a principal amount equal to that of the surrendered
Old Note. Accordingly, registered Holders of New Notes on the relevant record
date for the first interest payment date following the consummation of the
Exchange Offer will receive interest accruing from the most recent date to which
interest has been paid on the Old Note, or, if no interest has been paid, from
March 3, 1998. Old Notes accepted for exchange will cease to accrue interest
from and after the date of consummation of the Exchange Offer. Pursuant to the
Registration Rights Agreement, certain Liquidated Damages are required to be
made to Holders of Old Notes under certain circumstances relating to the timing
of the Exchange Offer and to other registration requirements contained therein.
Holders of Old Notes, who tender such Notes in the Exchange Offer agree to waive
any accrued but unpaid Liquidated Damages on such Old Notes. An amount equal to
the amount of accrued and unpaid Liquidated Damages on Old Notes tendered in the
Exchange Offer shall be payable to registered holders of New Notes on the record
date for the first interest payment following the consummation of the Exchange
Offer.
 
    In all cases, issuance of New Notes for Old Notes that are accepted for
exchange pursuant to the Exchange Offer will be made only after timely receipt
by the Exchange Agent of (i) certificates for such Old Notes or a timely
Book-Entry Confirmation of such Old Notes into the Exchange Agent's account at
the Book-Entry Transfer Facility, (ii) a properly completed and duly executed
Letter of Transmittal or an Agent's Message in lieu thereof and (iii) all other
required documents. If any tendered Old Notes are not accepted for any reason
set forth in the terms and conditions of the Exchange Offer or if Old Notes are
submitted for a greater principal amount than the Holder desires to exchange,
such unaccepted or non-exchanged Old Notes will be returned without expense to
the tendering Holder thereof (or, in the case of Old Notes tendered by
book-entry transfer into the Exchange Agent's account at the Book-Entry Transfer
Facility pursuant to the book-entry procedures described below, such
non-exchanged Old Notes will be credited to an account maintained with such
Book-Entry Transfer Facility) as promptly as practicable after the expiration or
termination of the Exchange Offer.
 
BOOK-ENTRY TRANSFERS
 
    The Exchange Agent will make a request to establish an account with respect
to the Old Notes at the Book-Entry Transfer Facility for purposes of the
Exchange Offer within two business days after the date of this Prospectus. Any
financial institution that is a participant in the Book-Entry Transfer Facility
systems
 
                                       42
<PAGE>
must make book-entry delivery of Old Notes by causing the Book-Entry Transfer
Facility to transfer such Old Notes into the Exchange Agent's accounts at the
Book-Entry Transfer Facility in accordance with such Book-Entry Transfer
Facility's Automated Tender Offer Program ("ATOP") procedures for transfer. Such
participant using ATOP should transmit its acceptance to the Book-Entry Transfer
Facility on or prior to the Expiration Date or comply with the guaranteed
delivery procedures described below. The Book-Entry Transfer Facility will
verify such acceptance, execute a book-entry transfer of the tendered Old Notes
into the Exchange Agent's account at the Book-Entry Transfer Facility and then
send to the Exchange Agent confirmation of such book-entry transfer, including
an Agent's Message confirming that the Book-Entry Transfer Facility has received
an express acknowledgment from such participant that such participant has
received and agrees to be bound by the Letter of Transmittal and that the
Company may enforce the Letter of Transmittal against such participant. However,
although delivery of Old Notes may be effected through book-entry transfer at
the Book-Entry Transfer Facility, an Agent's Message and any other required
documents, must, in any case, be transmitted to and received by the Exchange
Agent at the address set forth below under "--Exchange Agent" on or prior to the
Expiration Date or the guaranteed delivery procedures described below must be
complied with.
 
GUARANTEED DELIVERY PROCEDURES
 
    If a Holder of the Old Notes desires to tender such Old Notes and the Old
Notes are not immediately available, or time will not permit such Holders' Old
Notes or other required documents to reach the Exchange Agent before the
Expiration Date, or the procedure for book-entry transfer cannot be completed on
a timely basis, a tender may be effected if (i) the tender is made through an
Eligible Institution, (ii) prior to the Expiration Date, the Exchange Agent
received from such Eligible Institution a Notice of Guaranteed Delivery,
substantially in the form provided by the Company (by telegram, telex, facsimile
transmission, mail or hand delivery), setting forth the name and address of the
Holder of the Old Notes and the amount of Old Notes tendered, stating that the
tender is being made thereby and guaranteeing that within five New York Stock
Exchange ("NYSE") trading days after the date of execution of the Notice of
Guaranteed Delivery, the certificates for all physically tendered Old Notes, in
proper form for transfer, or a Book-Entry Confirmation, as the case may be,
together with a properly completed and duly executed appropriate Letter of
Transmittal (or facsimile thereof or Agent's Message in lieu thereof) with any
required signature guarantees and any other documents required by the Letter of
Transmittal will be deposited by the Eligible Institution with the Exchange
Agent, and (iii) the certificates for all physically tendered Old Notes, in
proper form for transfer, or a Book-Entry Confirmation, as the case may be,
together with a properly completed and duly executed appropriate Letter of
Transmittal (or facsimile thereof or Agent's Message in lieu thereof) with any
required signature guarantees and all other documents required by the Letter of
Transmittal, are received by the Exchange Agent within five NYSE trading days
after the date of execution of the Notice of Guaranteed Delivery.
 
WITHDRAWAL RIGHTS
 
    Tenders of Old Notes may be withdrawn at any time prior to 5:00 p.m., New
York City time, on the Expiration Date. For a withdrawal to be effective, a
written notice of withdrawal must be received by the Exchange Agent at one of
the addresses set forth below under "--Exchange Agent." Any such notice of
withdrawal must (i) specify the name of the person having tendered the Old Notes
to be withdrawn, (ii) identify the Old Notes to be withdrawn (including the
principal amount of such Old Notes), (iii) contain a statement that such Holder
is withdrawing his election to have such Old Notes exchanged, (iv) be signed by
the Holder in the same manner as the original signature on the Transmittal
Letter by which such Old Notes were tendered (including any signature
guarantees) or be accompanied by documents of transfer to have the Trustee with
respect to the Old Notes register the transfer of such Old Notes in the name of
the person withdrawing the transfer, and (v) (where certificates for Old Notes
have been transmitted) specify the name in which such Old Notes are registered,
if different from that of the withdrawing Holder. If certificates for Old Notes
have been delivered or otherwise identified to the
 
                                       43
<PAGE>
Exchange Agent, then, prior to the release of such certificates the withdrawing
Holder must also submit the serial numbers of the particular certificates to be
withdrawn and a signed notice of withdrawal with signatures guaranteed by an
Eligible Institution unless such Holder is an Eligible Institution. If Old Notes
have been tendered pursuant to the procedure for book-entry transfer described
above, any notice of withdrawal must specify the name and number of the account
at the Book-Entry Transfer Facility to be credited with the withdrawn Old Notes
and otherwise comply with the procedures of such facility. All questions as to
the validity, form and eligibility (including time of receipt) of such notices
will be determined by the Company, whose determination shall be final and
binding on all parties. Any Old Notes so withdrawn will be deemed not to have
been validly tendered for exchange for purposes of the Exchange Offer. Any Old
Notes which have been tendered for exchange but which are not exchanged for any
reason will be returned to the Holder thereof without cost to such Holder (or,
in the case of Old Notes tendered by book-entry transfer into the Exchange
Agent's account at the Book-Entry Transfer Facility pursuant to the book-entry
transfer procedures described above, such Old Notes will be credited to an
account maintained with such Book-Entry Transfer Facility for the Old Notes), as
soon as practicable after withdrawal, rejection of tender or termination of the
Exchange Offer. Properly withdrawn Old Notes may be retendered by following one
of the procedures described under "--Procedures for Tendering Old Notes" above
at any time on or prior to 5:00 p.m., New York City time, on the Expiration
Date.
 
CERTAIN CONDITIONS TO THE EXCHANGE OFFER
 
    Notwithstanding any other provision of the Exchange Offer, the Company shall
not be required to accept for exchange, or to issue New Notes in exchange for,
any Old Notes and may terminate or amend the Exchange Offer, if at any time
before the acceptance of such Old Notes, the Exchange Offer violates any
applicable law or regulation or interpretation of the Staff of the Commission.
 
    The foregoing conditions are for the sole benefit of the Company and may be
asserted by the Company regardless of the circumstances giving rise to any such
condition or may be waived by the Company in whole or in part at any time and
from time to time in its reasonable discretion. The failure by the Company at
any time to exercise any of the foregoing rights shall not be deemed a waiver of
any such right and each such right shall be deemed an ongoing right which may be
asserted at any time and from time to time.
 
    In addition, the Company will not accept for exchange any Old Notes
tendered, and no New Notes will be issued in exchange for any such Old Notes, if
at such time any stop order shall be threatened or in effect with respect to the
Registration Statement of which this Prospectus constitutes a part or the
qualification of the Indenture under the Trust Indenture Act of 1939, as
amended.

FEES AND EXPENSES
 
    The Company will not make any payment to brokers, dealers, or others
soliciting acceptances of the Exchange Offer except for reimbursement of mailing
expenses.
 
    The estimated cash expenses to be incurred in connection with the Exchange
Offer will be paid by the Company and are estimated in the aggregate to be
approximately $400,000.
 
TRANSFER TAXES
 
    Holders who tender their Old Notes for exchange will not be obligated to pay
any transfer taxes in connection with that exchange, as well as any other sale
or disposition of the Old Notes. However, Holders who instruct the Company to
register New Notes in the name of, or request that Old Notes not tendered or not
accepted in the Exchange Offer be returned to, a person other than the
registered tendering Holder will be responsible for the payment of any
applicable transfer tax thereon.
 
CONSEQUENCES OF NOT EXCHANGING OLD NOTES
 
    Holders of Old Notes who do not exchange their Old Notes for New Notes
pursuant to the Exchange Offer will continue to be subject to the provisions in
the Indenture regarding transfer and exchange of the Old Notes and the
restrictions on transfer of such Old Notes as set forth in the legend thereon as
a consequence of the issuance of the Old Notes pursuant to exemptions from, or
in transactions not subject to, the registration requirements of the Securities
Act and applicable state securities laws. In general, the Old Notes may not be
offered or sold, unless registered under the Securities Act, except pursuant to
an exemption from, or in a transaction not subject to, the Securities Act and
applicable state securities laws. The Company does not currently anticipate that
they will register under the Securities Act any Old Notes which remain
outstanding after consummation of the Exchange Offer (subject to certain limited
exceptions, if applicable). To the extent that Old Notes are not tendered and
accepted in the Exchange Offer, a holder's ability to sell such untendered Old
Notes could be adversely affected.
 
    Holders of the New Notes and any Old Notes which remain outstanding after
consummation of the Exchange Offer will vote together as a single class for
purposes of determining whether holders of the requisite percentage thereof have
taken certain actions or exercised certain rights under the Indenture.
 
                                       45
<PAGE>
    Upon consummation of the Exchange Offer, holders of Old Notes will not be
entitled to any Liquidated Damages or any further registration rights under the
Registration Rights Agreement, except under limited circumstances. See
"Description of Notes--Exchange Offer; Registration Rights."
 
CONSEQUENCES OF EXCHANGING OLD NOTES
 
    Based on interpretations by the staff of the Commission, as set forth in
no-action letters issued to third parties, the Company believes that New Notes
issued pursuant to the Exchange Offer in exchange for Old Notes may be offered
for resale, resold or otherwise transferred by Holders thereof (other than any
such Holder which is an "affiliate" of the Company within the meaning of Rule
405 under the Securities Act) without compliance with the registration and
prospectus delivery requirements of the Securities Act, provided that such New
Notes are acquired in the ordinary course of such Holder's business and such
Holder has no arrangement or understanding with any person to participate in the
distribution of such New Notes. However, the Commission has not considered the
Exchange Offer in the context of a no-action letter and there can be no
assurance that the staff of the Commission would make a similar determination
with respect to the Exchange Offer as in such other circumstances. Each Holder,
other than a broker-dealer, must acknowledge that it is not engaged in, and does
not intend to engage in, a distribution of such New Notes and has no arrangement
or understanding to participate in a distribution of New Notes. If any Holder is
an affiliate of the Company and is engaged in or intends to engage in or has any
arrangement or understanding with respect to the distribution of the New Notes
to be acquired pursuant to the Exchange Offer, such Holder (i) could not rely on
the applicable interpretations of the staff of the Commission and (ii) must
comply with the registration and prospectus delivery requirements of the
Securities Act in connection with any resale transaction. Each broker-dealer
that receives New Notes for its own account in exchange for Old Notes must
acknowledge that such Old Notes were acquired by such broker-dealer as a result
of market-making activities or other trading activities and that it will deliver
this Prospectus in connection with any resale of such New Notes. See "Plan of
Distribution." In addition, to comply with the securities laws of certain
jurisdictions (including any jurisdiction outside the United States), the New
Notes may not be offered or sold unless they have been registered or qualified
for sale in such jurisdiction or an exemption from registration or qualification
is available and is complied with. The Company has agreed, pursuant to the
Registration Rights Agreement, subject to certain limitations specified therein,
to register or qualify the New Notes for offer or sale under all applicable
state or Blue Sky securities laws by the time the Registration Statement (of
which this Prospectus forms a part) is declared effective by the Commission.

                                    BUSINESS
 
THE COMPANY
 
    The Company is a leading provider of outsourced manufacturing and packaging
services to the North American health and beauty aid market on the basis of
sales. Over 75% of the Company's revenues are derived from the manufacturing and
packaging of health and beauty aid products, including lipstick, face powder,
eye shadow, mascara, nail enamel, skin care cream and lotion, hair spray and
gel, shampoo and shaving cream and gel. Other products manufactured and packaged
by the Company include household and automotive products such as lubricant,
household cleaners and lighter fluid. OSG offers its customers a complete range
of services, including product conceptualization, formulation, manufacturing,
filling and packaging. It also provides ancillary services such as materials
procurement, warehousing and distribution of finished goods. The Company has
developed hundreds of proprietary products that have been placed into
distribution by its customers in national and international consumer markets.
Management estimates that a majority of the Company's revenues are derived from
products that OSG has formulated. The Company has six manufacturing facilities
strategically located in the United States and Canada, in addition to facilities
in Australia and Mexico. Management believes OSG is the largest independent
contract manufacturer and packager of color cosmetics, high-end salon aerosol
hair care products and shaving creams and gels in North America. The Company had
revenues of $79.8 million, $110.3 million and $115.0 million for the years ended
December 31, 1996 and 1997 and for the six month period ended June 27, 1998,
respectively. The Company had net losses of $6.2 million, $1.5 million and $2.2
million for the years ended December 31, 1996 and 1997 and for the six month
period ended June 27, 1998, respectively.
 
   
    The Company's customers include over 350 companies that market branded
and/or private label consumer products in the health and beauty aid, household
and automotive markets. Customers include Mary Kay Corp. ("Mary Kay"), Sebastian
International Inc. ("Sebastian") and WD-40 Co. ("WD-40"), as well as other
nationally branded marketers and numerous regional or niche marketers. The
Company's top ten customers have been with the Company for 17 years on average,
and nine of those top ten have been customers for at least ten years. The
Company believes that its ability to develop long-term relationships is due to
its product formulation expertise, manufacturing reliability, consistent product
quality and timely delivery. Many of OSG's customers lack in-house manufacturing
capabilities and outsource their manufacturing and packaging requirements in
order to focus on marketing. Management estimates that a majority of the
Company's revenues are derived from customers that do not have in-house
manufacturing capabilities for the products OSG manufactures. Companies with the
necessary in-house manufacturing capabilities utilize the Company's services for
new product launches, lower volume brands and to supplement internal capacity.
    
 
    Contract manufacturers and packagers manufacture products to customer
specifications and fill containers for a wide range of industries. Contract
manufacturers typically charge a per-unit fee which varies depending on: (i) the
type of product, (ii) the type of services provided (filling only versus product
development, formulation, materials procurement, etc.), (iii) the container size
and order quantity, and (iv) the complexity of the manufacturing and packaging
process. The contract manufacturing and packaging industry is highly fragmented,
with hundreds of independent companies typically providing a narrow scope of
services in limited geographic areas. Competition is based principally on
formulation capabilities, product quality, reputation, service, dependability,
and cost-effectiveness. When the cost of distribution is a significant factor in
the total product cost or if customers desire geographic proximity to suppliers,
competition tends to be regionally based. Management believes that few
competitors offer the scale, expertise, reputation and range of services that
the Company provides.
 
COMPETITIVE STRENGTHS
 
    OSG attributes its leading market position to the following factors:
 
                                       47
<PAGE>
    FORMULATION EXPERTISE.  Management believes that OSG is highly regarded for
its product formulation capabilities. OSG's research and development chemists
have developed hundreds of proprietary products on behalf of its customers that
have been placed into distribution. Products developed by OSG include numerous
hair care products, such as hair sprays for the high-end salon market, color
cosmetics, such as long-lasting silicone lipstick and other products, including
a new product for WD-40. In addition, OSG is at the forefront of the
reformulation of aerosol products in response to changing government
regulations. Management believes that the Company's formulation expertise is
highly valued by its customers, resulting in greater customer loyalty and the
opportunity for revenue growth. Management estimates that a majority of the
Company's revenues are derived from products that OSG has formulated.
 
   
    LONG-STANDING CUSTOMER RELATIONSHIPS.  The Company believes that its strong,
long-standing customer relationships provide it with a distinct competitive
advantage. OSG provides contract manufacturing and packaging services to over
350 customers worldwide, including some of the best-known and most successful
consumer product companies. OSG's top ten customers have been customers for over
17 years on average, and include Sebastian, Mary Kay and WD-40. All but one of
the top-ten customers have used the Company's services for more than ten years.
    
 
    LEADER IN NICHE MARKETS.  The Company focuses on market sectors requiring
specialized manufacturing and/or formulation capabilities such as color
cosmetics, high-end salon aerosol hair care products and shaving creams and
gels. As a result of its value-added manufacturing and formulation services,
management believes that it is able to retain customers and obtain higher profit
margins than contract packagers of commodity-type products. Management believes
the Company is the leading contract manufacturer and packager of color
cosmetics, high-end salon aerosol hair care products and shaving creams and gels
in North America on the basis of sales.
 
   
    FULL SERVICE CAPABILITIES.  The Company offers a full array of services,
including materials procurement, blending, filling, packaging, warehousing and
distribution. The Company's full service product offering and manufacturing
expertise provides it with a competitive advantage in keeping existing customers
and attracting new ones. OSG's size, capabilities and reputation make it one of
the few contract manufacturers and packagers in the health and beauty aid
markets capable of supporting large scale production runs and product launches
for customers such as Mary Kay.
    
 
    MANUFACTURING EXPERTISE.  The Company has the equipment and manufacturing
expertise required to manufacture and package a wide variety of color cosmetic,
aerosol, cream, lotion and liquid products while adhering to strict product
specifications for its customers. For example, the Company is able to fill
complex containers such as barrier packs (pressurized, non-aerosol containers),
which have made it a leader in manufacturing and packaging products such as
shaving gels. As a result of these capabilities, the Company is a highly valued
partner to its customers, providing consistently high quality products in a
timely, cost-effective manner. As further evidence of OSG's manufacturing
expertise and quality operations, all four of the Company's facilities that
manufacture and package products for Procter & Gamble, have been awarded Procter
& Gamble's prestigious Pinnacle Award for Good Manufacturing Practices.
 
    STRATEGIC LOCATIONS.  OSG's facilities are strategically located to service
regional, national and international customers. With its largest color cosmetics
facility located in New York City, the Company is close to the fashion and
cosmetic industry. In addition, management believes the Company is the largest
independent aerosol packager on the West Coast and in the Southeast. OSG can
manufacture and package various products at each of its facilities, creating
flexibility in servicing its geographically diverse customers in a
cost-effective manner. The Company's facilities in Mexico and Australia serve
the requirements of both international and local customers.
 
    EXPERIENCED MANAGEMENT TEAM.  OSG's management team, headed by the former
President of Kolmar, Christopher Denney, has extensive industry experience. Upon
joining Kolmar in 1994, Mr. Denney implemented numerous initiatives that
increased sales and returned Kolmar to profitability.
 
                                       48
<PAGE>
Members of senior management have spent a majority of their careers in the
packaging industry, averaging 24 years of experience. In addition, Walter K.
Lim, the founder of ASC, serves as Chairman of OSG, and Samuel D. Garretson, the
founder of Piedmont, serves as a director of OSG.
 
BUSINESS STRATEGY
 
    The Company intends to increase its sales and profitability by capitalizing
on its product conceptualization and formulation expertise and its
cost-effective, quality manufacturing capabilities. In addition, management
believes that it can continue to improve the Company's operating results by
implementing the following strategies:
 
    CAPITALIZE ON CROSS-SELLING OPPORTUNITIES.  OSG intends to capitalize on the
combination of each of its subsidiaries' respective customer bases, product
lines and geographical locations. The Company expects to increase product
penetration of its customer base by capturing business that previously exceeded
each of its subsidiaries' particular areas of expertise. For example, the
Company has developed proprietary color cosmetics formulations for Sebastian
International, Inc., a customer that traditionally focused on hair care
products, and expects to offer color cosmetic products to other hair care
product customers. In addition, the Company can offer its aerosol capabilities
to its color cosmetics customers. The geographic diversity of OSG's facilities
allows the Company to offer its customers multiple production locations.
 
    CENTRALIZE SALES AND MARKETING.  Historically, OSG has managed its sales
efforts at the plant level. The Company plans to centralize the management of
its sales efforts in order to improve communication with customers, to
cross-sell services to customers and to ensure uniform pricing and sales
strategies. The Company plans to establish a group specifically focused on
promoting innovation within OSG and to its customers. This innovation group will
be responsible for identifying market trends and assisting customers with new
product ideas, as well as promoting the Company through customer presentations,
advertising and trade shows. Local sales and management staff will continue to
maintain close ties with customers and production facilities. The centralized
sales effort will enable the Company to serve national accounts more effectively
and to pursue customers located outside the local marketing reach of each
individual plant.
 
    INCREASE INTERNATIONAL PRESENCE.  As a result of increased international
demand for cosmetic products, global cosmetics companies have started to expand
into markets such as Eastern Europe, Latin America and the Asia-Pacific region.
OSG intends to capitalize on this trend by increasing its export sales and
selectively entering into joint ventures and licensing agreements. The Company
currently has licensing agreements in Japan, Korea, Thailand and Poland. In
addition, the Company plans to continue to develop its own "control" brands --
brands for which OSG owns the formulas and manufactures and packages the
products to its own specifications, leaving the marketing, promotion and
distribution to its customer. To date, OSG has developed two control brands
which are manufactured at its Mexico facility--"Veronique," which is primarily
exported to Russia, and "Maria," a brand targeted at Latin American markets.
 
    REDUCE MANUFACTURING COSTS.  The Company continues to improve its
cost-effectiveness by investing in productivity enhancements and implementing
operational improvements. The Company believes that the combination of ASC,
Kolmar and Piedmont will result in cost reductions from (i) allocating
production among facilities to better optimize the use of labor and equipment;
(ii) eliminating redundant administrative operations; and (iii) in certain
cases, purchasing larger amounts of raw materials on more favorable terms.
 
    PURSUE STRATEGIC ACQUISITIONS.  Management intends to pursue acquisitions to
expand into new product lines, niche markets and new geographic areas. The
Kolmar Acquisition represents a continuation of OSG's strategy to provide more
services to existing and potential customers in the highly fragmented contract
manufacturing and packaging industry. OSG plans to acquire companies that will
provide additional cross-selling and cost-reduction opportunities.

CUSTOMERS AND PRODUCTS
 
    The Company's customers include over 350 companies that market branded
and/or private label consumer products in the health and beauty aid, household
and automotive markets. OSG's customers vary in size from large, international,
branded consumer product companies with diverse product lines to small,
entrepreneurial companies with narrower product offerings. The Company
specializes in the manufacturing of color cosmetic, aerosol, cream, lotion and
liquid products.
 
    COLOR COSMETIC PRODUCTS.  Color cosmetic products include lipstick, face
powder, eye shadow, mascara and nail enamel. The Company manufactures and
packages color cosmetics for the entire range of major cosmetic market sectors
from budget to high-end. Management estimates that retail revenues in the color
cosmetics industry were approximately $3.3 billion in 1996 (representing an
approximate 3.6% annual growth rate since 1993). In order to respond to and
drive fashion trends, marketers continually change their product offerings. By
offering product conceptualization and formulation expertise and manufacturing
flexibility, the Company helps its customers remain current with market trends.
 
    Management believes that the Company is the largest independent contract
manufacturer of color cosmetics in North America on the basis of sales. For the
three month period ended March 28, 1998, 1997 and 1996, OSG's revenues from
color cosmetic products were $15.1 million, $14.6 million and $15.0 million,
representing approximately 28.1%, 27.5% and 30.6% of revenues, respectively.
 
   
    OSG's customers for color cosmetic products include Mary Kay and Sebastian.
    
 
    AEROSOL PRODUCTS.  Aerosol products include a broad range of products such
as hair spray, shaving cream and gel, lubricant, non-stick cooking spray and
household cleaning products. The aerosol system is one of the most effective
forms of delivering products in a cost-effective manner, while providing dosage
control, sanitary use and convenience. Management estimates that in 1996, over
approximately 3.2 billion aerosol units were filled in the United States
(representing an approximate 1.8% annual growth rate since 1990). The aerosol
products market has undergone significant change as certain states have enacted
regulations requiring reduced VOC emissions, resulting in the reformulation of
aerosol products to meet these new standards. The Company has reformulated over
100 products in response to legislative changes. Not only must packagers of
aerosol products obtain government permits, but the packaging process also
requires specialized equipment and expertise.
 
    The Company's success in the aerosol market is enhanced by its product
conceptualization, formulation and technological capabilities. The Company has
technological expertise with complex delivery systems such as barrier packs
(non-aerosol, pressurized products). In addition, many high-end salon aerosol
hair care companies rely on the Company's formulation expertise, making it the
largest aerosol contract manufacturer and packager of high-end hair care
products in North America on the basis of sales.
 
    In addition to its success in the health and beauty aid industry, the
Company produces several aerosol products for the household and automotive
markets, including lubricants, bathroom cleaners, tire sealers and dry wall
repair products.
 
    Management believes that the Company is the second largest independent
aerosol contract manufacturer and packager in North America and the largest in
shaving creams and gels, on the basis of sales. For the three month period ended
March 28, 1998, 1997, and 1996, OSG's revenues from aerosol products were $22.9
million, $22.2 million and $21.4 million, representing approximately 42.5%,
41.9% and 43.7% of revenues, respectively.
 
   
    OSG's customers for aerosol products include Sebastian and WD-40.
    
 
    CREAM, LOTION AND LIQUID PRODUCTS.  Creams and lotions consist of skin care
products such as facial preparations, hand and body care products, sun care and
anti-aging products. Management estimates that the skin care market is one of
the largest and fastest growing sectors of the health and beauty aid market,
 
                                       50
<PAGE>
estimated at $6 billion in revenues in 1996 (representing an approximate 7.5%
annual growth rate since 1993). The Company began emphasizing skin care products
in 1994 after recognizing the growth potential in this market, and such products
have grown to approximately 20% of the Company's revenues. Other liquid products
manufactured and packaged by OSG include shampoo, conditioner, fragrance, pump
hair spray and gel and non-aerosol deodorant, as well as products for the
household and automotive markets such as lighter fluid, lubricant and cleaning
products.
 
    For the three month period ended March 28, 1998, 1997, and 1996, OSG's
revenues from cream, lotion and liquid products were $15.9 million, $16.2
million and $12.6 million, representing approximately 29.4%, 30.6% and 25.7% of
revenues, respectively.
 
   
    OSG's customers for cream, lotion and liquid products include Sebastian and
WD-40 (3-in-1 Oil).
    
 
MARKETING AND SALES
 
    The Company has 14 full-time sales representatives located at the Company's
various manufacturing facilities. The Company's sales efforts are supported by
35 in-house customer service representatives who ensure timely delivery of
products and services. The Company plans to centralize the management of its
sales efforts in order to improve its communications with customers, to
cross-sell its services to customers, and to ensure uniform pricing and sales
strategies. Coordination of these efforts will occur at the national level and
at each facility. Marketing will include a small group specifically focused on
promoting innovation within OSG and to its customers. This innovation group will
be responsible for increasing customer demand for OSG products by following
market trends, suggesting new product ideas and promoting the Company through
customer presentations, advertising and trade shows. Other members of the sales
and management staff will continue to be located at each plant in order to
maintain close ties with local customers and the production side of the
business.
 
FORMULATION
 
    Management believes that OSG is highly regarded for its product formulation
capabilities. The Company's laboratory facilities are staffed with development
chemists and microbiologists who have developed hundreds of proprietary products
on behalf of the Company's customers that have been placed into distribution.
Products developed by OSG include numerous hair care products, such as hair
spray for the high-end salon market, color cosmetics, such as long-lasting
silicone lipstick and other products, including a new product for WD-40. The
Company's formulation expertise allows it to adapt customer formulations, which
may have been originally developed on a small scale, into formulas that can be
manufactured in large scale batch formulations. Additionally, the Company is
able to act as a fast-follower in developing products for customers shortly
after such products have been successfully launched by other marketers. OSG is
also at the forefront of the reformulation of aerosol products in response to
changing government regulations. Management believes that the Company's
formulation expertise is highly valued by its customers, resulting in greater
customer loyalty and opportunity for revenue growth. Management estimates that a
majority of the Company's revenues are derived from products that OSG has
formulated.
 
RAW MATERIALS
 
    Some of OSG's customers provide raw materials for product manufacturing and
packaging, while in other cases, OSG procures raw materials for its customers.
If customers supply raw materials, the Company charges only a per unit fill fee
for its services. In the event OSG purchases raw materials from third party
suppliers, OSG passes the cost of such materials on to its customers, and
charges a handling fee in addition to the fill fee. Raw materials are purchased
from approved suppliers by the Company's buyers to meet specific production
requirements and customer specifications. The Company's primary raw materials
consist of cans, propellants, chemicals, valves, oils, talc, wax, colorants,
fragrances, thickeners, caps, bottles, cartons and tubes. While OSG strives to
maintain close relationships with its suppliers, the Company generally does not
enter into long-term contracts with them. The Company is not reliant on any
 
                                       51
<PAGE>
one supplier for any of its raw materials. Additionally, certain key customers
have recently changed the way materials are sourced, resulting in greater
reliance on the Company. This gives OSG greater control over its production
planning and inventory levels.
 
PRODUCTION AND MANUFACTURING
 
    The Company's manufacturing process results in timely delivery of high
quality products to customers on a cost-effective basis. OSG provides its
customers with a full range of services including product conceptualization,
formulation, manufacturing, filling and packaging, materials procurement,
warehousing and shipping of finished goods. The manufacturing process
incorporates several distinct steps which require coordination in order to
ensure flexibility and short lead times, match product standards and achieve
high throughput. Certain manufacturing operations within the facilities are
compartmentalized (e.g., all lipsticks are manufactured and packaged in one area
of the facility) in order to enhance quality control and minimize the potential
for cross contamination of products.
 
    In connection with each order, OSG procures raw materials for products and
packaging or accepts delivery of such materials from its customers. The raw
materials are inspected by quality control, after which OSG manufactures the
product in batches. When the batch is complete, quality assurance testing is
performed. In addition to the Company's own rigorous quality assurance
procedures, several of OSG's customers specify additional levels of testing
throughout the formulation and manufacturing process. OSG fills the product into
packaging containers for shipment to customers or in some instances ships the
final product batch in bulk form to its customers.
 
COMPETITION
 
    The contract manufacturing and packaging industry is highly fragmented. OSG
not only competes with other independent contract manufacturers, but also with
marketers that have self-manufacturing capabilities. Competition is based
principally on formulation capabilities, quality, reputation, service,
dependability, and cost-effectiveness. When the cost of distribution is a
significant factor in the total product cost, or if customers desire geographic
proximity to suppliers for faster service and closer communication, competition
tends to be regionally based. Management believes that few competitors offer the
scale, expertise, reputation and range of services that the Company provides.
Management also believes that there are hundreds of contract manufacturers and
packagers servicing the color cosmetic, aerosol, cream, lotion and liquid
products markets. OSG's main competitors in these market sectors include
Intercos Italia Spa, Davlyn Industries Inc., CCL, Accra-Pac Group, Bocchi
Laboratories, Inc., Cosmetic Essence Inc., Shield Packaging Co., Fluid Packaging
Co., Inc., San-Mar Laboratories, Packaging Advantage Corporation and
Alberto-Culver (Cosmetic Labs).

which management believes is material to the Company's business.
 
EMPLOYEES
 
    As of June 27, 1998, after giving effect to the Kolmar Acquisition, OSG
employed approximately 2,060 persons, of which approximately 440 are salaried
and approximately 1,520 are compensated on an hourly basis. In addition, the
Company utilizes local labor contract suppliers to provide a significant portion
of its production labor force. None of OSG's employees in the United States
belong to a union. Approximately 200 of OSG's employees in Mexico belong to a
union and approximately 80 of OSG's employees in Australia belong to one of two
unions. The Australia and Mexico union contracts expire in 1999 and 1998,
respectively. The Company has not experienced a significant work stoppage with
its employees. Management believes that its employee and union relationships are
good. The Company has employment agreements with certain key personnel. See
"Management-Employment Agreements."
 
TRADE NAMES, TRADEMARKS, FORMULAS AND PATENTS
 
    OSG owns certain trade names, trademarks, formulas and patents which are
used in its business. Management believes that its development and formulation
expertise, manufacturing experience and know-how are more critical in
maintaining and growing its business than patents or trademarks. Consistent with
industry practice, management does not patent its proprietary formulas.
 
                                       53
<PAGE>
LEGAL PROCEEDINGS
 
    From time to time, OSG and its subsidiaries may become party to various
legal proceedings involving routine claims which are incidental to their
businesses. The legal and financial liability of OSG and its subsidiaries with
respect to such matters cannot be estimated at the present time, but OSG and its
subsidiaries do not expect that such matters would have a material adverse
effect on the business, results of operations or financial condition of OSG
taken as a whole.
 
ENVIRONMENTAL ISSUES, COMPLIANCE AND GOVERNMENT REGULATION
 
    ENVIRONMENTAL REGULATION AND COMPLIANCE.  The Company's operations and
properties are subject to 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 or financial condition.
 
    Certain environmental laws, such as 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 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 a volumetric or other standard, 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 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
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 acquisition, the Los Angeles Regional Water
Quality Control Board ("RWQCB") requested that ASC conduct certain soil and
groundwater investigation and remediation on its property. ASC has conducted
 
                                       54
<PAGE>
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. The EPA has estimated that it
will cost $8.8 million to clean up the site. Under current allocation estimates,
Kolmar and Wickhen will be responsible for most of these costs. Kolmar and
Wickhen's insurer has accepted coverage of this claim, and presently is
controlling the defense and paying related costs. It is anticipated that the
insurance coverage will be sufficient to pay for the estimated remedial costs.
In addition, the Company has received a full indemnity for liability at this
site from CCL. Based on the foregoing, the Company does not believe that the
Company's liability at this site will be material. Kolmar also has been
identified as a PRP at several other sites where it sent waste for off-site
disposal. In addition, another site where a Kolmar affiliate formerly operated
currently is undergoing remediation under the direction of a state agency. Based
on currently available information concerning the estimated remediation costs
and the responsibility of other parties for contamination at these sites, as
well as the insurance coverage and the indemnity for these matters from CCL, the
Company does not believe that Kolmar's related liability will have a material
adverse effect on the Company's business, results of operations or financial
condition. There can be no assurance, however, that these matters will not have
such an effect, or that the Company will not incur liability at additional sites
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. Piedmont has requested that the state agency remove the facility from
the HSI based upon Piedmont's understanding that no persons are exposed to
groundwater that may have been impacted by the facility. There can be no
assurance, however, that the Company's proposal will be approved by the state as
submitted or that the state will delist the site without requiring further
remedial action. The former owners of Piedmont have provided a partial indemnity
for remediation costs incurred at the facility. The Company believes that its
share of remediation costs, if any, 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 propellants could materially adversely affect the Company's
business if the industry does not develop propellant technology and product
formulations to meet such future standards. California and New York recently
have mandated reductions in VOCs 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
propellant technology and product formulations will be developed that meet the
future standards. See "--Environmental Issues, Compliance and Government
Regulation."
 
    ERISA.  Management believes that OSG is in material compliance with all laws
and regulations governing its employee benefit plans. Management believes OSG
has sufficient cash flow to meet its obligations to make pension contributions
and to pay related premiums. However, there can be no assurance that future
changes in such laws or regulations, or interpretations thereof, changes in
OSG's business or in market conditions affecting the value of plan assets will
not require OSG to expend amounts that exceed those that are now anticipated.
 
    EMPLOYEE HEALTH AND SAFETY REGULATION.  The Company's operations are subject
to a variety of worker safety laws. OSHA and analogous laws mandate general
requirements for safe workplaces for all employees. The Company believes that
its operations are in material compliance with applicable employee health and
safety laws.
 
                                       55
<PAGE>
    STATE AND FEDERAL REGULATION.  The Company's manufacturing and packaging of
over-the-counter pharmaceuticals, which accounts for a small percentage of
revenues, and cosmetics is subject to regulation by the FDA and by various state
agencies, especially the California Department of Health Services. Any failure
by the Company to remain in compliance with the regulations promulgated by these
agencies could have a material adverse effect on the Company's business.
 
    The Company must also adhere to state and federal regulations governing
"good manufacturing practices," including testing, quality control,
manufacturing, inspection, and documentation requirements for certain products.
Although the Company has had no difficulty in complying with these regulations
to date, if violations of such regulations are noted during inspections of the
Company's manufacturing facilities, the Company may be required or may elect to
cease manufacturing and packaging at the facility in violation, pending
resolution of the violation. In these circumstances, the Company may also be
required or may elect to recall products that were manufactured under improper
conditions. Although the Company has had no difficulty in complying with these
regulations to date, there can be no assurance that any future federal or state
regulation of the Company's business will not have a material adverse impact on
the Company's business, results of operations or financial condition.
 
    MINIMUM WAGES.  The Company utilizes local labor contractors at its various
facilities to provide a significant portion of its production labor force. The
Company is subject to the Fair Labor Standards Act as well as various federal,
state and local regulations that govern such matters as minimum wage
requirements, overtime and working conditions. A large number of the Company's
employees, including those provided by local labor contractors, are paid at or
just above the federal minimum wage level and, accordingly, changes in laws,
regulations or ordinances could have a material adverse effect on the Company by
increasing the Company's costs.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
STOCKHOLDER AGREEMENT AND REGISTRATION RIGHTS AGREEMENT
 
    In connection with the Merger, each stockholder of the Company at that time
executed an amended and restated stockholder agreement, dated June 30, 1997 (the
"Original Stockholder Agreement"), a copy of which has been filed as an exhibit
to the Registration Statement of which this Prospectus constitutes a part,
setting forth the rights, obligations and restrictions by and among the Company
and its stockholders. In contemplation of the Kolmar Acquisition, on December
31, 1997, the Original Stockholder Agreement was amended by an amendment to
stockholder agreement (the "Amendment"), a copy of which has been filed as an
exhibit to the Registration Statement of which this Prospectus constitutes a
part. The Original Stockholder Agreement and the Amendment are referred to
herein as the "Stockholder Agreement." The rights, obligations and restrictions
set forth in the Stockholder Agreement include, but are not limited to, the
following: (a) restrictions on sales, pledges and other transfers of Common
Stock by the Company's stockholders (the "Stockholders") except in certain
circumstances; (b) the right of certain individuals who are part of management
of the Company to sell their shares of Common Stock to the Company upon
termination of employment by the Company without cause or upon the death or
disability, retirement or resignation for "good reason" (as defined therein) of
such person; (c) the right of the Company to purchase shares of Common Stock of
certain Stockholders in certain circumstances; (d) restrictions on the purchase
of shares of Common Stock by the Company in certain circumstances; (e) a right
of first refusal in favor of the Company and the Stockholders in certain
circumstances; and (f) the right to compel a sale or merger of the Company. The
obligation of the Company to purchase shares of Common Stock of certain
management employees pursuant to clause (b) above may be deferred in certain
circumstances, including to the extent that the Company is prohibited by any
debt instruments entered into by the Company or any of its affiliates or by law.
In the event such payment is deferred, it shall accrue interest at a rate of 9%
per annum until paid in full.
 
    The Stockholder Agreement requires that, unless certain events have
occurred, each Stockholder will nominate, elect and vote all of such
Stockholder's shares of Common Stock to continue in office a Board of Directors
consisting of nine members, three of whom will be designated by the Founders
(Samuel D. Garretson, Walter K. Lim and Howard C. Lim) and must be reasonably
acceptable to GMIP; two of whom will be designated by HarbourVest; three of whom
will be designated by GMIP; and one of whom will be Christopher Denney, so long
as he is Chief Executive Officer of the Company and is willing to serve. The
persons designated by the Founders, HarbourVest and GMIP may be changed from
time to time by the Founders, HarbourVest and GMIP, respectively, provided,
however, that Walter K. Lim, Howard C. Lim and Samuel D. Garretson will each be
one of the directors named by the Founders so as long as he holds at least
thirty-three percent (33%) of the Common Stock he held on December 31, 1997 and
is willing to serve. If both Michael S. Gordon and John H. Morris are no longer
principals of the manager of GMIP, then HarbourVest will have the right to name
one of the directors GMIP would otherwise have the right to name, provided that
HarbourVest is, at such time, the beneficial owner of at least ten percent (10%)
of the Common Stock. If either GMIP and its affiliates or HarbourVest and its
affiliates no longer hold at least 33% of the highest number of shares of Common
Stock held by them at any time, the rights of GMIP or HarbourVest, as
appropriate, to name a director will terminate. On each date that any one of
Walter K. Lim, Howard C. Lim and Samuel D. Garretson ceases to own at least 33%
of the Common Stock he held on December 31, 1997, the number of directors to be
named by the Founders will decrease by one, and when all three of such Founders
cease to own at least 33% of the Common Stock that each held on December 31,
1997, the Founders shall no longer have the right to name any directors. If
Christopher Denney ceases to be a director because he is no longer Chief
Executive Officer, Mr. Denney's directorship will be filled by the incoming
Chief Executive Officer.
 
    Certain parties to the Original Stockholder Agreement previously entered
into a registration rights agreement with the Company on February 14, 1994
providing certain piggyback registration rights relating to their shares of
Common Stock.

    In connection with financing the Kolmar Acquisition, the Company sold
2,093,000 shares of Common Stock for an aggregate purchase price of $20.9
million to GMIP, Walter K. Lim and HVP-V. On September 30, 1996, ACHC, the sole

existing stockholders of the Company, including Walter K. Lim, Howard C. Lim,
GMIP and HarbourVest, as well as certain other new investors, at a purchase
price of $10.00 per share in connection with the Piedmont acquisition. On June

1,267,174 shares of Common Stock in the Company as a result of the Merger.
Pursuant to the Merger, 3,750 shares of the Company's unclassified preferred
stock owned by Nancy Lim were exchanged for the Company's Series A Preferred
Stock (as defined) and 26,250 shares of the Company's unclassified preferred
stock owned by Walter K. Lim and Howard C. Lim were exchanged for the Company's
Series B Preferred Stock (as defined). In each case, such transactions,
including the conversion ratios, were approved by a majority of the independent
directors of the Company. See "Description of Acquisition Agreements."
 
MANAGEMENT SERVICE AGREEMENTS
 
    The Company, ASC, Piedmont, Kolmar and G+MG are parties to an Amended and
Restated Management Services Agreement, dated January 8, 1998 (the "Management
Services Agreement"), a copy of which has been filed as an exhibit to the
Registration Statement of which this Prospectus constitutes a part, which
supersedes all prior management agreements with G+MG. Pursuant to this
agreement, G+MG agreed to provide financial advisory, consulting and other
management services to the Company. The Company paid G+MG a fee of $800,000 upon
the closing of the Kolmar Acquisition and will pay G+MG (i) provided certain
conditions are met, an annual fee of $350,000 which is subject to adjustment in
the event of further acquisitions and/or dispositions, (ii) provided certain
ownership conditions are met at the closing of each acquisition of an additional
business an amount equal to 1% (or a different amount agreed to by the parties
up to 2%) of the total consideration paid to third parties, including assumption
of debt, (iii) provided certain ownership conditions are met, upon the sale of
the Company or any of its subsidiaries, an amount equal to 1% (or a different
amount agreed to by the parties up to 2%) of the consideration received,
including the assumption of debt, (iv) at the closing of a debt refinancing
transaction an amount equal to 0.5% (or a different amount agreed to by the
parties up to 1%) of the amount refinanced and (v) reasonable out-of-pocket
expenses. This agreement contains broad indemnification provisions benefitting
G+MG. Since January 1, 1994, the Company has paid G+MG a total of approximately
$1.9 million (up to but not including the fee for the Kolmar Acquisition) under
the Management Services Agreement and predecessor agreements. The Management
Services Agreement was approved by a majority of the independent directors of
the Company.
 
    The Company is also party to a letter agreement with HarbourVest, dated
January 8, 1998 (the "HarbourVest Agreement"), a copy of which has been filed as
an exhibit to the Registration Statement of which this Prospectus constitutes a
part, whereby HarbourVest has agreed to provide a representative to serve on the
Company's Board of Directors and to render financial and business advice to OSG.
In return, the Company will (i) reimburse the HarbourVest designated OSG
director for all reasonable expenses related to attending meetings, (ii)
provided certain ownership conditions are met, pay HarbourVest a $115,000 annual
financial advisory fee, $50,000 of which shall be paid in cash and the remainder
of which shall accrue, all subject to increase if the management fees paid to
G+MG are increased and (iii) pay HarbourVest a fee of 1/3 of the fee received by
G+MG or any of its affiliates under the Management Services Agreement upon the
sale of OSG or any of its subsidiaries or, if approved by OSG's Board of
Directors, upon the acquisition of additional businesses. The HarbourVest
Agreement was approved by a majority of the independent directors of the
Company.

ASC INVESTMENT PARTNERS, L.P.
 
    ASCIP was formed on February 3, 1994 as a Delaware limited partnership
pursuant to an Agreement of Limited Partnership which was amended on March 27,
1996. ASCIP acquired 100,000 shares of ASHC's common stock in ASHC's acquisition
of ASC, which shares were exchanged for 75,648 shares of Common Stock in the
Merger; both transactions were on the same terms as those terms for other
stockholders. John H. Morris and Michael S. Gordon, directors of the Company,
and Bruce N. Lipian, are shareholders, officers and directors of ASCIP's general
partner and indirectly exercise voting and investment power over the shares held
by ASCIP. Each of Joseph A. Marino, Drew H. Adams and Frank Edelstein, directors
of the Company, or their affiliates, are limited partners of ASCIP and do not
exercise voting and investment power over the shares held by ASCIP.
 
PURCHASES FROM THE LIMS
 
    The Company leases its manufacturing and warehouse facilities located in the
City of Industry, as well as certain equipment located therein, from Walter K.
Lim, Sylvia Lim, Howard C. Lim, Nancy Lim, and their affiliates. The Company
believes these leases were entered into in the ordinary course of business on
terms no less favorable than could be obtained from a third party in an
arms-length transaction and were approved by the Board of Directors of the
Company. Between January 1, 1995, and June 27, 1998, the Company paid
approximately $3.6 million to Walter K. Lim, Sylvia Lim, Howard C. Lim, Nancy
Lim, and their affiliates, under all such leases.
 
    The Company has sold products to companies controlled by Walter K. Lim,
Howard C. Lim, and their affiliates, in the amount of $100,000 and $119,000 and
$227,000 for the years ended December 31, 1995, 1996 and 1997, respectively. The
Company believes that these sales were made in the ordinary course of business
on terms no less favorable than could have been obtained from a third party in
an arms-length transaction.
 
AMENDMENT TO CERTIFICATE OF INCORPORATION
 
    In accordance with the Kolmar Acquisition, the Company's Certificate of
Incorporation was amended with respect to the Preferred Stock (as defined) in
order to extend the redemption date of the Preferred Stock until after the
maturity of the Notes.
 
MANAGEMENT PRIVATE PLACEMENT
 
   
    On September 10, 1998, the Company sold, by way of a private placement,
95,000 shares of its Common Stock to certain of its and its subsidiaries'
managers, including two of the Named Executive Officers, Mr. Hewson and Mr.
Sortais, and Mr. Denney and Mr. Nolan at a purchase price of $10.00 per share.
In most cases, the Company financed up to 80% (except for Mr. Nolan, for whom
the Company financed 100%) of the aggregate purchase price of each manager's
subscription. In each such case, the respective manager executed a promissory
note and pledged all of his or her shares to the Company to secure his or her
obligation under the promissory note. The Common Stock sold to management was
not registered under the Securities Act. Mr. Sortais purchased less than $60,000
worth of Common Stock, 80% of which purchase was financed by the Company. Mr.
Denney, Mr. Hewson and Mr. Nolan purchased 20,000, 10,000 and 10,000, shares of
Common Stock, respectively, and the Company loaned to these individuals
$160,000, $80,000 and $100,000, respectively, to finance the purchase of such
stock. Indebtedness under the promissory notes (i) bears interest at the rate of
8.0% per annum, payable on the first business day of each month commencing
September 1, 1998 and (ii) is due in full upon the earlier to occur of (a) the
date on which the borrowers' shares of Common Stock are repurchased by the
Company and (b) December 31, 2002.

              DESCRIPTION OF CERTAIN TERMS OF THE PREFERRED STOCK
                           AND THE WARRANT AGREEMENT
 
PREFERRED STOCK
 
    The following is a description of the general terms of the Preferred Stock
of the Company. This information relating to the Preferred Stock is qualified in
its entirety by reference to the Certificate of Amendment of Certificate of
Incorporation of OSG, dated January 8, 1998, a copy of which has been filed as
an exhibit to the Registration Statement of which this Prospectus constitutes a
part. This document is available upon request from the Company.
 
    The Company has issued and outstanding 30,000 shares of Preferred Stock
("Preferred Stock"), 3,750 shares of which are designated as "Series A Preferred
Stock," par value of $.001 per share and 26,250 shares of which are designated
as "Series B Preferred Stock," par value $.001 per share. Neither class of
Preferred Stock has voting rights, except as provided by law. Holders of Series
A Preferred Stock are entitled to a noncumulative dividend ("Series A Current
Dividend") in cash equal to $2.50 per share per quarter. If the Series A Current
Dividend is not declared and paid, then the Series A Preferred Stock holders are
entitled to a cumulative dividend ("Series A Deferred Dividends") in cash equal
to $3.25 per share for the quarter preceding the dividend payment date, subject
to quarterly increases of 2.5% of such dividend or, if Series A Current
Dividends and all Series A Deferred Dividends are not timely paid, 3.25% of such
dividend. Holders of Series B Preferred Stock are entitled to receive cumulative
dividends ("Series B Dividends") in cash equal to $2.00 per share per quarter.
Series B Dividends accrue whether or not they have been declared. At any time
after the completion of an offering by the Company of its shares of Common Stock
pursuant to an effective registration statement filed with the Securities and
Exchange Commission or at any time after June 30, 2000, the Company may, at the
option of its Board of Directors, redeem all or part of the outstanding shares
of Preferred Stock or a series thereof at a redemption price of $100.00 per
share of Series A Preferred Stock, plus all accrued and unpaid dividends thereon
through the date of redemption (the "Series A Redemption Price"), and $145.97
per share of Series B Preferred Stock, plus all accrued and unpaid dividends
thereon through the date of redemption (the "Series B Redemption Price"). The
Company must redeem all outstanding Preferred Stock upon the earlier of (i) a
liquidation, dissolution or winding up of the Company, (ii) an initial public
offering of Common Stock which results in net proceeds of not less than $20.0
million to the Company and (iii) June 30, 2010. Upon a change of control (as
defined therein) at the option of the holders of a majority of the Preferred
Stock, the Company shall redeem all outstanding shares of Series A Preferred
Stock at the Series A Redemption Price and all outstanding shares of Series B
Preferred Stock at the Series B Redemption Price. As of June 27, 1998, dividends
on the Series A Preferred Stock had accrued in the amount of $18,800, but $9,400
remain unpaid, and dividends on the Series B Preferred Stock had accrued in the
amount of $105,000, but remain unpaid.
 
WARRANT AGREEMENT
 
    The following is a description of the general terms of the Warrant Agreement
(as defined). This information relating to the Warrant Agreement is qualified in
its entirety by reference to the Warrant Agreement. This document is available
upon request from the Company.
 
    In connection with the issuance of $6 million of the Company's 12% senior
subordinated notes to Chase Manhattan Capital, L.P. or its transferee ("Chase
Manhattan") on June 30, 1997 (which notes were refinanced as part of the Kolmar
Acquisition), the Company entered into a warrant agreement with Chase Manhattan.
Pursuant to this warrant agreement, Chase Manhattan received a warrant to
purchase 80,833 shares of Common Stock at an exercise price of $.01 per share
(the "Warrant"). In contemplation of the Offering, the Company and Chase
Manhattan entered into an Amended and Restated Warrant Agreement (the "Warrant
Agreement"), dated as of January 8, 1998, a copy of which has been filed as an
exhibit to the Registration Statement of which this Prospectus constitutes a
part, which supersedes the prior warrant agreement.
 
                                       67
<PAGE>
    Under the Warrant Agreement, Chase Manhattan retained the Warrant, which is
exercisable immediately and expires on June 30, 2007. The Warrant Agreement
provides for certain anti-dilution rights and restrictions on transferability in
addition to certain registration, tag along, drag along and preemptive rights.
Pursuant to the Warrant Agreement, if the Company purchases or redeems any
shares of its Common Stock from affiliates of the Company, Chase Manhattan shall
have the right to cause the Company to purchase the Warrant or shares of Common
Stock owned by Chase Manhattan that were acquired pursuant to exercise of the
Warrant ("Warrant Stock") on the same terms, subject to certain quantity and
other restrictions. In addition, at any time or from time to time after June 30,
2002, but prior to the earlier of (i) an initial public offering of the Common
Stock pursuant to an effective registration statement under the Securities Act
with proceeds of at least $10.0 million before the payment of underwriting
discounts and commissions (an "IPO") and (ii) June 30, 2007, Chase Manhattan
shall have the right to require the Company to purchase all or any portion of
the Warrant and Warrant Stock at the fair market value of the Common Stock on
the date the right is exercised ("Purchase Price"). If the Company is prohibited
from purchasing all Warrant and Warrant Stock pursuant to Chase Manhattan's
request because of insufficient funds or contractual restrictions, the Purchase
Price with respect to such unpurchased Warrant or Warrant Stock will become an
accruing liability of the Company with interest accruing thereon at 12.5% per
annum, compounded quarterly (the "Accruing Liability"). The Accruing Liability
shall be subordinated in right of payment to the prior payment in full of all
Senior Debt of the Company (as defined in the Warrant Agreement). At any time or
from time to time after June 30, 2003, but prior to the earlier of (i) an IPO
and (ii) June 30, 2007, the Company shall have the right to purchase all (but
not less than all) of the Warrant and Warrant Stock at the fair market value of
the Common Stock on that date.
 
    Without the prior consent of Chase Manhattan, the Warrant Agreement
prohibits (i) the Company and its subsidiaries from repurchasing or redeeming
shares of Common Stock, except for shares repurchased or redeemed from
management, other than on a PRO RATA basis from all of the Company's
shareholders and Chase Manhattan; (ii) the Company and its subsidiaries from
selling, leasing or otherwise transferring any property or assets to, or
purchasing, leasing or otherwise acquiring any property or assets from, or
otherwise engaging in any other transactions with, any of the Company's
affiliates, except (a) in the ordinary course, (b) transactions between or among
the Company and its wholly-owned subsidiaries, (c) any transactions existing as
of January 8, 1998 or (d) other transactions permitted by the Warrant Agreement;
(iii) the Company from entering into any agreement or instrument limiting in any
manner its ability to perform its obligations under the Warrant Agreement or the
Warrants, other than the Subordinated Bridge Facility and the Senior Secured
Credit Facility and any refinancing thereof (including the Notes); and (iv) the
Company from amending any provisions of the Company's employee stock option
plan, Stockholder Agreement and organizational documents in any manner that
would have an adverse effect on Chase Manhattan's rights under the Warrant,
without the prior consent of Chase Manhattan.
 
                     DESCRIPTION OF ACQUISITION AGREEMENTS
 
ASC ACQUISITION AGREEMENT
 
    ASHC (subsequently renamed OSG), a holding corporation formed for such
purpose, acquired on February 14, 1994, through a merger, Aerosol Services
Company, Inc. (predecessor to ASC) from Walker K. Lim and Howard C. Lim (the
"Lims") for $32.0 million in cash and $3.0 million of preferred stock in ASHC
pursuant to that certain purchase and merger agreement (the "ASC Acquisition
Agreement"), dated as of February 14, 1994, a copy of which has been filed as an
exhibit to the Registration Statement of which this Prospectus constitutes a
part. Pursuant to the ASC Acquisition Agreement, Aerosol Services Company, Inc.
(predecessor to ASC) was merged into a newly-formed subsidiary of ASHC. The
newly-formed subsidiary of ASHC survived the merger and was renamed ASC.
Pursuant to the ASC Acquisition Agreement, the Lims are required, subject to a
$0.4 million minimum threshold, to indemnify ASC and OSG for losses resulting
from inaccuracies or breaches of representations and warranties, including
losses resulting from undisclosed hazardous materials and other environmental
liabilities, and for breaches of post-closing covenants. The
 
                                       68
<PAGE>
Lims' liability to the Company for indemnification is limited to $3.0 million
except for indemnifiable losses incurred with respect to the representations and
warranties relating to title, employee benefits, employment laws, environmental
laws and taxes, for which liability is unlimited and there is no $0.4 million
minimum threshold. In connection with the ASC Acquisition Agreement, the Lims
executed amendments to their leases with ASC to provide an offset against lease
payments as a means of satisfying environmental indemnities under the ASC
Acquisition Agreement.
 
PIEDMONT ACQUISITION AGREEMENT
 
    ACHC, a holding company formed for such purpose, acquired on September 30,
1996, all of the shares of Piedmont from Samuel D. Garretson and certain other

refinancing of debt totaling $14.1 million pursuant to that certain stock
purchase agreement, dated as of June 27, 1996 (the "Piedmont Acquisition
Agreement"), a copy of which has been filed as an exhibit to the Registration

$325,000 minimum threshold in most cases, for losses resulting from inaccuracies
or breaches of representations and warranties, including losses resulting from
undisclosed hazardous materials and other environmental liabilities, and for
breaches of post-closing covenants. The Sellers' liability for indemnification
under the Piedmont Acquisition Agreement is limited to $1.0 million.
 
KOLMAR ACQUISITION AGREEMENT
 
    As of January 1, 1998, OSG acquired all of the shares of Kolmar from CCL
Industries and certain assets relating to Kolmar's Canadian operations from CCL
for an aggregate purchase price of $78.0 million, subject to certain
post-closing adjustments, pursuant to a share and asset purchase agreement dated
October 28, 1997, as it was amended by that certain letter agreement dated
January 1, 1998 and by that certain modification agreement dated January 8, 1998
(collectively the "Kolmar Acquisition Agreement"), a copy of which has been
filed as an exhibit to the Registration Statement of which this Prospectus
constitutes a part. Upon consummation of the Kolmar Acquisition, Kolmar became a
wholly-owned subsidiary of OSG and those other assets purchased from CCL were
transferred to Kolmar Canada Inc., an Ontario corporation formed for such
purpose, which became a wholly-owned subsidiary of Kolmar. Pursuant to the
Kolmar Acquisition Agreement and subject to a $134,000 minimum threshold in one
lawsuit, CCL retained liability for all disclosed litigation. The Kolmar
Acquisition Agreement contains typical representations and warranties, which for
the most part shall survive until the earlier of (i) July 8, 1999 or (ii)
delivery of Kolmar's audited financial statements for the year ending December
31, 1998. Certain representations and warranties made with respect to compliance
with environmental laws survive until January 8, 2003. CCL and CCL Industries
agreed to indemnify the Company for losses resulting from inaccuracies or
breaches of representations and warranties and breaches of certain covenants
contained in the agreement. Subject to a $750,000 minimum threshold and for
certain environmental liabilities subject to a $250,000 minimum threshold, CCL
and CCL Industries' liability for indemnification is limited to $6.5 million
(this limit is $12.0 million with respect to losses resulting from environmental
matters related to certain facilities and there is no limit with respect to
losses from environmental matters related to certain other facilities). Pursuant
to the terms of the Kolmar Acquisition Agreement, OSG is required to indemnify
CCL and CCL Industries for losses resulting from breaches or inaccuracies of its
representations and warranties and for losses arising from the Company's conduct
of Kolmar's business, its real property and environmental matters, to the extent
that the losses relate to actions or occurrences after the closing date.

Borrowers to finance working capital, other permitted corporate purposes and
permitted acquisitions (the "Revolving Credit Facility"). The amount available
to individual Borrowers is limited by a formula as set forth in the Senior
Secured Credit Facility based on that Borrower's accounts receivable, inventory,
equipment and real property with the maximum aggregate amount available to all
Borrowers capped at $70.0 million. This information relating to the Senior
Secured Credit Facility is qualified in its entirety by reference to the
complete text of the Senior Secured Credit Facility and the other documents
entered into in connection therewith. The following is a description of the
general terms of the Senior Secured Credit Facility which is available upon
request from the Company.
 
    Indebtedness of the Borrowers under the Senior Secured Credit Facility is
guaranteed by the Company and, with respect solely to Kolmar Laboratories, Inc.
by Kolmar Canada Inc. ("Kolmar Canada"), and will be guaranteed by future
domestic subsidiaries of the Company and future subsidiaries of the Company
designated as "Subsidiary Guarantors" pursuant to the Senior Secured Credit
Facility. Such indebtedness is secured by, or will be secured by, (i) the
assets, including accounts receivable, inventory, equipment, certain real
property, intellectual property and intercompany indebtedness of each Borrower,
the Company and Kolmar Canada, (ii) a pledge of all of the stock of each
domestic subsidiary of the Company, (iii) a pledge of 66% of the stock of each
foreign subsidiary of the Company and (iv) a pledge by each foreign subsidiary
of the Company of intercompany notes.
 
    At the option of the Borrowers, indebtedness under the Senior Secured Credit
Facility bears interest at a floating rate based on (i) the Prime Lending Rate
(defined as the rate which BTCo announces as its prime lending rate from time to
time), plus 0.75% (the "Base Rate Margin") or (ii) the Eurodollar Rate (defined
as the rate of the offered quotation, if any, to first class banks in the
Eurodollar market by BTCo for U.S. dollar deposits) for one, two, three or six
months, in each case plus 2.25% (the "Eurodollar Rate Margin"). The Base Rate
Margin and Eurodollar Rate Margin are subject to adjustment pursuant to the
terms of the Senior Secured Credit Facility. The Borrowers shall pay to the
Lenders an unused line fee equal to 0.375% per annum of the average daily
unutilized portion of the Revolving Credit Facility, payable monthly, in
accordance with the provisions of the Senior Secured Credit Facility. The
Borrowers shall also pay to the Lenders letter of credit fees as set forth in
the Senior Secured Credit Facility.
 
    Loans made under the Revolving Credit Facility may be repaid and reborrowed.
The Revolving Credit Facility matures on December 31, 2002, subject to earlier
termination pursuant to the terms of the Senior Secured Credit Facility.
Mandatory prepayments of the Revolving Credit Facility shall be made from all
net proceeds from the Offering in excess of amounts used to repay the
Subordinated Bridge Facility and from all insurance proceeds received upon the
loss or destruction of the Company's assets or properties.
 
    The Senior Secured Credit Facility provides that the Company and its
subsidiaries must meet certain financial tests, including minimum EBITDA,
minimum fixed charge coverage ratios and maximum funded debt ratios. The Senior
Secured Credit Facility also contains covenants which, among other things, limit
the incurrence of additional indebtedness and contingent obligations,
investments, dividends, transactions with affiliates, asset sales, acquisitions,
mergers and consolidations, prepayments of other indebtedness, the creation of
liens and encumbrances, capital expenditures and other matters customarily
restricted in such agreements.
 
    The Senior Secured Credit Facility contains customary events of default,
including payment defaults, breach of representations and warranties, covenant
defaults, cross-defaults to certain other indebtedness, certain events of
bankruptcy and insolvency, judgment defaults, certain changes of control of the
Company, its subsidiaries and certain affiliates and the cessation of the
enforceability of the Senior Secured Credit Facility or any other document
executed in connection therewith or the security interests granted thereby.

                              DESCRIPTION OF NOTES
 
    The New Notes will be issued under the indenture (the "Indenture"), dated as
of March 3, 1998, by and among the Company, the Guarantors and U.S. Bank Trust
National Association (formerly First Trust National Association), as Trustee,
(the "Trustee"), a copy of which has been filed as an exhibit to the
Registration Statement of which this Prospectus constitutes a part. The New
Notes are identical in all material respects to the terms of the Old Notes
except (i) that the New Notes have been registered under the Securities Act,
(ii) for certain transfer restrictions and registration rights relating to the
Old Notes and (iii) that the New Notes will not contain certain provisions
relating to Liquidated Damages to be paid to the Holders of Old Notes under
certain circumstances relating to the timing of the Exchange Offer and to other
registration requirements described below under "--Exchange Offer; Registration
Rights." The Trustee will authenticate and deliver New Notes for original issue
only in exchange for a like principal amount of Old Notes. Any Old Notes that
remain outstanding after the consummation of the Exchange Offer, together with
the New Notes, will be treated as a single class of securities under the
Indenture.
 
    The following summary of certain provisions of the Indenture does not
purport to be complete and is subject to, and is qualified in its entirety by
reference to, the Trust Indenture Act of 1939, as amended (the "TIA"), and to
all of the provisions of the Indenture, including the definitions of certain
terms therein and those terms made a part of the Indenture by reference to the
TIA as in effect on the date of the Indenture. A copy of the Indenture may be
obtained from the Company or BT. The definitions of certain capitalized terms
used in the following summary are set forth below under "--Certain Definitions."
For purposes of this section, references to the "Company" include only the
Company and not its Subsidiaries.
 
    The Notes will be unsecured obligations of the Company, ranking subordinate
in right of payment to all Senior Debt of the Company.
 
    The New Notes will be, and the Old Notes are, issued in fully registered
form only, without coupons, in denominations of $1,000 and integral multiples
thereof. Initially, the Trustee will act as paying agent and registrar for the
Notes. The Notes may be presented for registration or transfer and exchange at
the offices of the Registrar, which initially will be the Trustee's corporate
trust office. The Company may change any paying agent and registrar without
notice to holders of the Notes (the "Holders"). The Company will pay principal
(and premium, if any) on the Notes at the Trustee's corporate office in New
York, New York. At the Company's option, interest may be paid at the Trustee's
corporate trust office or by check mailed to the registered address of Holders.
For purposes of this section, references to the "Notes" include the Old Notes
and the New Notes, unless the context otherwise requires.
 
PRINCIPAL, MATURITY AND INTEREST
 
    The Notes are limited in aggregate principal amount to $130,000,000, of
which $105,000,000 will be issued in the Offering, and will mature on March 1,
2006. Additional amounts may be issued in one or more series from time to time
subject to the limitations set forth under "--Certain Covenants--Limitation on
Incurrence of Additional Indebtedness" and restrictions contained in the Credit
Agreement. Interest on the Notes will accrue at the rate of 10 7/8% per annum
and will be payable semiannually in arrears and in cash on each March 1 and
September 1, commencing on September 1, 1998, to the persons who are registered
Holders at the close of business on the February 15 and August 15, respectively,
immediately preceding the applicable interest payment date. Interest on the
Notes will accrue from the most recent date to which interest has been paid or,
if no interest has been paid, from and including the date of issuance. Interest
will be computed on the basis of a 360-day year of twelve 30-day months.
Registered holders of New Notes on the relevant record date for the first
interest payment date following the consummation of the Exchange Offer will
receive interest accruing from the most recent date to which interest has been
paid or, if no interest has been paid, from March 3, 1998. Old Notes accepted
for exchange will cease to accrue interest from and after the date of
consummation of the Exchange Offer. Holders whose Old Notes are accepted for
exchange will not receive any payment in respect of interest on
 
                                       71
<PAGE>
such Old Notes otherwise payable on any interest payment date the record date
for which occurs on or after the consummation of the Exchange Offer.
 
    The Notes will not be entitled to the benefit of any mandatory sinking fund.
 
REDEMPTION
 
    OPTIONAL REDEMPTION.  The Notes will be redeemable, at the Company's option,
in whole at any time or in part from time to time, on and after March 1, 2003,
upon not less than 30 nor more than 60 days' notice, at the following redemption
prices (expressed as percentages of the principal amount thereof) if redeemed
during the twelve-month period commencing on March 1 of the year set forth
below, plus, in each case, accrued and unpaid interest thereon, if any, to the
date of redemption:

</TABLE>
 
    OPTIONAL REDEMPTION UPON EQUITY OFFERINGS.  At any time, or from time to
time, on or prior to March 1, 2001, the Company may, at its option, use the net
cash proceeds of one or more Equity Offerings to redeem up to 35% of the
aggregate principal amount of Notes originally issued at a redemption price
equal to 110.875% of the principal amount thereof plus accrued and unpaid
interest thereon, if any, to the date of redemption; PROVIDED that at least 65%
of the principal amount of New Notes issued hereunder together with the Old
Notes originally issued and not exchanged in the Exchange Offer remains
outstanding immediately after any such redemption. In order to effect the
foregoing redemption with the proceeds of any Equity Offering, the Company shall
make such redemption not more than 120 days after the consummation of any such
Equity Offering.
 
SELECTION AND NOTICE OF REDEMPTION
 
    In the event that less than all of the Notes are to be redeemed at any time,
selection of such Notes for redemption will be made by the Trustee in compliance
with the requirements of the principal national securities exchange, if any, on
which such Notes are listed or, if such Notes are not then listed on a national
securities exchange, on a PRO RATA basis, by lot or by such method as the
Trustee shall deem fair and appropriate; PROVIDED, HOWEVER, that no Notes of a
principal amount of $1,000 or less shall be redeemed in part; PROVIDED, FURTHER,
that if a partial redemption is made with the proceeds of an Equity Offering,
selection of the Notes or portions thereof for redemption shall be made by the
Trustee only on a PRO RATA basis or on as nearly a PRO RATA basis as is
practicable (subject to The Depository Trust Company's procedures, if
applicable), unless such method is otherwise prohibited. Notice of redemption
shall be mailed by first-class mail at least 30 but not more than 60 days before
the redemption date to each Holder of Notes to be redeemed at its registered
address. If any Note is to be redeemed in part only, the notice of redemption
that relates to such Note shall state the portion of the principal amount
thereof to be redeemed. A new Note in a principal amount equal to the unredeemed
portion thereof will be issued in the name of the Holder thereof upon
cancellation of the original Note. On and after the redemption date, interest
will cease to accrue on Notes or portions thereof called for redemption as long
as the Company has deposited with the paying agent funds in satisfaction of the
applicable redemption price pursuant to the Indenture.
 
SUBORDINATION
 
    The payment of all Obligations on the Notes is subordinated in right of
payment to the prior payment in full in cash or Cash Equivalents of all
Obligations on Senior Debt. Upon any payment or distribution of assets of the
Company of any kind or character, whether in cash, property or securities, to
creditors upon
 
                                       72
<PAGE>
any liquidation, dissolution, winding up, reorganization, assignment for the
benefit of creditors or marshaling of assets of the Company or in a bankruptcy,
reorganization, insolvency, receivership or other similar proceeding relating to
the Company or its property, whether voluntary or involuntary, all Obligations
due or to become due upon all Senior Debt shall first be paid in full in cash or
Cash Equivalents, or such payment duly provided for to the satisfaction of the
holders of Senior Debt, before any payment or distribution of any kind or
character is made on account of any Obligations on the Notes, or for the
acquisition of any of the Notes for cash or property or otherwise. If any
default occurs and is continuing in the payment when due, whether at maturity,
upon any redemption, by declaration or otherwise, of any principal of, interest
on, unpaid drawings for letters of credit issued in respect of, or regularly
accruing fees with respect to, any Senior Debt (a "Payment Default"), no payment
of any kind or character shall be made by or on behalf of the Company or any
other Person on its behalf with respect to any Obligations on the Notes or to
acquire any of the Notes for cash or property or otherwise unless and until such
default has been cured, waived or has ceased to exist or such Senior Debt shall
have been discharged or paid in full in cash, or in any other manner acceptable
to the holders of such Senior Debt.
 
    In addition, if any event of default other than a Payment Default (a
"Non-payment Default") occurs and is continuing with respect to any Designated
Senior Debt, as such event of default is defined in the instrument creating or
evidencing such Designated Senior Debt, permitting the holders of such
Designated Senior Debt then outstanding to accelerate the maturity thereof and
if the Representative for the respective issue of Designated Senior Debt gives
written notice of the Non-payment Default to the Trustee (a "Default Notice"),
then, unless and until all Non-payment Defaults have been cured or waived or
have ceased to exist or the Trustee receives notice from the Representative for
the respective issue of Designated Senior Debt terminating the Blockage Period
(as defined below), during the 180 days after the delivery of such Default
Notice (the "Blockage Period"), neither the Company nor any other Person on its
behalf shall (x) make any payment of any kind or character with respect to any
Obligations on the Notes or (y) acquire any of the Notes for cash or property or
otherwise. Notwithstanding anything herein to the contrary, in no event will a
Blockage Period extend beyond 180 days from the date the payment on the Notes
was due and only one such Blockage Period may be commenced within any 360
consecutive days. No Non-payment Default which existed or was continuing on the
date of the commencement of any Blockage Period with respect to the Designated
Senior Debt shall be, or be made, the basis for commencement of a second
Blockage Period by the Representative of such Designated Senior Debt whether or
not within a period of 360 consecutive days, unless such Non-payment Default
shall have been cured or waived for a period of not less than 90 consecutive
days (it being acknowledged that any subsequent action or any breach of any
financial covenants for a period commencing after the date of commencement of
such Blockage Period that, in either case, would give rise to a Non-payment
Default pursuant to any provisions under which a Non-payment Default previously
existed or was continuing shall constitute a new Non-payment Default for this
purpose).
 
    By reason of such subordination, in the event of the insolvency of the
Company, creditors of the Company who are not holders of Senior Debt, including
the Holders of the Notes, may recover less, ratably, than holders of Senior
Debt.
 
    As of June 27, 1998, the Company had no Senior Debt Outstanding.
 
HOLDING COMPANY
 
    The Company is a holding company for its Subsidiaries, with no material
operations of its own and only limited assets. Accordingly, the Company is
dependent upon the distribution of the earnings of its Restricted Subsidiaries,
whether in the form of dividends, advances or payments on account of
intercompany obligations, to service its debt obligations. There can be no
assurance that, after providing for all prior claims, there would be sufficient
assets available from the Company and the Guarantors to satisfy the claims of
the Holders of Notes. See "Risk Factors--Holding Company Structure; Effects of
Asset Encumbrance."
 
                                       73
<PAGE>
GUARANTEES
 
    Each Guarantor unconditionally guarantees, on a full, unconditional, joint
and several and unsecured senior subordinated basis, jointly and severally, to
each Holder and the Trustee, the full and prompt performance of the Company's
obligations under the Indenture and the Notes, including the payment of
principal of and interest on the Notes. The Guarantees will be subordinated to
Guarantor Senior Debt on the same basis as the Notes are subordinated to Senior
Debt. As of June 27, 1998, the Guarantors had no Guarantor Senior Debt and the
Guarantors had approximately $52.1 million of availability under the Senior
Secured Credit Facility. Each Guarantor and each Holder irrevocably agrees
pursuant to the Indenture that the obligations of each Guarantor under its
Guarantee will not exceed the maximum that such Guarantor could incur without
such obligations constituting an avoidable fraudulent transfer or conveyance
under such laws, taking into account (if necessary), among other things, all
other debts of such Guarantor (including, without limitation, any contingent or
unliquidated debts and such Guarantor's Guarantor Senior Debt) at the time that
such Guarantor entered into its Guarantee or became obligated to make any
payment thereunder, as appropriate. Each Guarantor that makes a payment under a
Guarantee shall be entitled to receive from each other Guarantor a reimbursement
amount as set forth in the Indenture.
 
    Each Guarantor may consolidate with or merge into or sell its assets to the
Company or another Guarantor that is a Restricted Subsidiary of the Company
without limitation, or with other Persons upon the terms and conditions set
forth in the Indenture. See "--Certain Covenants--Merger, Consolidation and Sale
of Assets." In the event all of the Capital Stock of a Guarantor is sold by the
Company and the sale complies with the provisions set forth in "--Certain
Covenants--Limitation on Asset Sales," the Guarantor's Guarantee will be
released. Each Guarantor that is designated as an Unrestricted Subsidiary in
accordance with the Indenture shall be released from its Guarantee and related
obligations set forth in the Indenture for so long as it remains an Unrestricted
Subsidiary.
 
CHANGE OF CONTROL
 
    The Indenture will provide that upon the occurrence of a Change of Control,
each Holder will have the right to require that the Company purchase all or a
portion of such Holder's Notes pursuant to the offer described below (the
"Change of Control Offer"), at a purchase price equal to 101% of the principal
amount thereof plus accrued interest to the date of purchase.
 
    Within 30 days following the date upon which the Change of Control occurred,
the Company must send, by first class mail, a notice to each Holder, with a copy
to the Trustee, which notice shall govern the terms of the Change of Control
Offer. Such notice shall state, among other things, the purchase date for the
Notes, which must be no earlier than 30 days nor later than 45 days from the
date such notice is mailed, other than as may be required by law (the "Change of
Control Payment Date"). Holders electing to have a Note purchased pursuant to a
Change of Control Offer will be required to surrender the Note, with the form
entitled "Option of Holder to Elect Purchase" on the reverse of the Note
completed, to the paying agent at the address specified in the notice prior to
the close of business on the third business day prior to the Change of Control
Payment Date.
 
    If a Change of Control Offer is made, there can be no assurance that the
Company will have available funds sufficient to pay the purchase price for all
the Notes that might be delivered by Holders seeking to accept the Change of
Control Offer. In the event the Company is required to purchase outstanding
Notes pursuant to a Change of Control Offer, the Company expects that it would
seek third party financing to the extent it does not have available funds to
meet its purchase obligations. However, there can be no assurance that the
Company would be able to obtain such financing.
 
    Neither the Board of Directors of the Company nor the Trustee may waive the
covenant relating to a Holder's right to redemption upon a Change of Control
without the consent of the Holders of a majority in principal amount of the then
outstanding Notes. Restrictions in the Indenture described herein on the
 
                                       74
<PAGE>
ability of the Company and its Restricted Subsidiaries to incur additional
Indebtedness, to grant liens on its property, to make Restricted Payments and to
make Asset Sales may also make more difficult or discourage a takeover of the
Company, whether favored or opposed by the management of the Company.
Consummation of any such transaction in certain circumstances may require
redemption or repurchase of the Notes, and there can be no assurance that the
Company or the acquiring party will have sufficient financial resources to
effect such redemption or repurchase. Such restrictions and the restrictions on
transactions with Affiliates may, in certain circumstances, make more difficult
or discourage any leveraged buyout of the Company or any of its Subsidiaries by
the management of the Company. While such restrictions cover a wide variety of
arrangements which have traditionally been used to effect highly leveraged
transactions, the Indenture may not afford the Holders of Notes protection in
all circumstances from the adverse aspects of a highly leveraged transaction,
reorganization, restructuring, merger or similar transaction.
 
    The Credit Agreement prohibits the Company from purchasing any Notes and
also provides that certain change of control events (including a Change of
Control) with respect to the Company would constitute a default thereunder. Any
future credit agreements or other agreements relating to Senior Debt to which
the Company becomes a party may contain similar restrictions and provisions. In
the event a Change of Control occurs at a time when the Company is prohibited
from purchasing Notes, the Company could seek the consent of its lenders to
purchase the Notes or could attempt to refinance the borrowings that contain
such prohibition. If the Company does not obtain such a consent or repay such
borrowings, the Company will remain prohibited from purchasing Notes. In such
case, the Company's failure to purchase tendered Notes would constitute an Event
of Default under the Indenture, which would, in turn, constitute a default under
the Credit Agreement. In such circumstances, the subordination provisions in the
Indenture would likely restrict payments to the Holders of Notes.
 
    The Company will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with the
repurchase of Notes pursuant to a Change of Control Offer. To the extent that
the provisions of any securities laws or regulations conflict with the "Change
of Control" provisions of the Indenture, the Company shall comply with the
applicable securities laws and regulations and shall not be deemed to have
breached its obligations under the "Change of Control" provisions of the
Indenture by virtue thereof.
 
CERTAIN COVENANTS
 
    The Indenture will contain, among others, the following covenants:
 
    LIMITATION ON INCURRENCE OF ADDITIONAL INDEBTEDNESS.  The Company will not,
and will not permit any of its Restricted Subsidiaries to, directly or
indirectly, create, incur, assume, guarantee, acquire, become liable,
contingently or otherwise, with respect to, or otherwise become responsible for
payment of (collectively, "incur") any Indebtedness (other than Permitted
Indebtedness); PROVIDED, HOWEVER, that if no Default or Event of Default shall
have occurred and be continuing at the time of or as a consequence of the
incurrence of any such Indebtedness, the Company or any of its Restricted
Subsidiaries may incur Indebtedness (including, without limitation, Acquired
Indebtedness) if on the date of the incurrence of such Indebtedness, after
giving effect to the incurrence thereof, the Consolidated Fixed Charge Coverage
Ratio of the Company is greater than 2.0 to 1.0 if the Indebtedness is incurred
prior to March 1, 2000 and greater than 2.25 to 1.0 if the Indebtedness is
incurred thereafter.
 
    LIMITATION ON RESTRICTED PAYMENTS.  The Company will not, and will not cause
or permit any of its Restricted Subsidiaries to, directly or indirectly, (a)
declare or pay any dividend or make any distribution (other than dividends or
distributions payable in Qualified Capital Stock of the Company) on or in
respect of shares of the Company's Capital Stock to holders of such Capital
Stock, (b) purchase, redeem or otherwise acquire or retire for value any Capital
Stock of the Company or any warrants, rights or options
 
                                       75
<PAGE>
to purchase or acquire shares of any class of such Capital Stock, (c) make any
principal payment on, purchase, defease, redeem, prepay or otherwise acquire or
retire for value, prior to any scheduled final maturity, scheduled repayment or
scheduled sinking fund payment, any Indebtedness of the Company that is
subordinate or junior in right of payment to the Notes or (d) make any
Investment (other than Permitted Investments) (each of the foregoing actions set
forth in clauses (a), (b), (c) and (d) being referred to as a "Restricted
Payment"), if at the time of such Restricted Payment or immediately after giving
effect thereto, (i) a Default or an Event of Default shall have occurred and be
continuing or (ii) the Company is not able to incur at least $1.00 of additional
Indebtedness (other than Permitted Indebtedness) in compliance with the
"Limitation on Incurrence of Additional Indebtedness" covenant or (iii) the
aggregate amount of Restricted Payments (including such proposed Restricted
Payment) made subsequent to the Issue Date (the amount expended for such
purposes, if other than in cash, being the fair market value of such property as
determined reasonably and in good faith by the Board of Directors of the
Company) shall exceed the sum of: (w) 50% of the cumulative Consolidated Net
Income (or if cumulative Consolidated Net Income shall be a loss, minus 100% of
such loss) of the Company earned subsequent to the Issue Date and through the
last day of the fiscal quarter ending prior to the date the Restricted Payment
occurs (the "Reference Date") (treating such period as a single accounting
period); plus (x) 100% of the aggregate net cash proceeds received by the
Company from any Person (other than a Subsidiary of the Company) from the
issuance and sale subsequent to the Issue Date and on or prior to the Reference
Date of Qualified Capital Stock of the Company, including the net cash proceeds
received by the Company upon the exercise, exchange or conversion of
Indebtedness or Disqualified Capital Stock into Qualified Capital Stock; plus
(y) to the extent not otherwise included in Consolidated Net Income of the
Company, an amount equal to the net reduction in Investments (other than
reductions in Permitted Indebtedness) in Unrestricted Subsidiaries resulting
from dividends, interest payments, repayments of loans or advances, or other
transfers of cash, in each case, to the Company or to any Wholly-Owned
Restricted Subsidiary of the Company from Unrestricted Subsidiaries, or from
redesignations of Unrestricted Subsidiaries as Restricted Subsidiaries (in each
case valued as provided in the definition of "Investment"), not to exceed, in
the case of an Unrestricted Subsidiary, the amount of Investments previously
made by the Company or any Restricted Subsidiary of the Company in such
Unrestricted Subsidiary and which were treated as a Restricted Payment under the
Indenture; plus (z) without duplication of any amounts included in clause
(iii)(x) above, 100% of the aggregate net cash proceeds of any equity
contribution received by the Company from a holder of the Company's Capital
Stock (excluding, in the case of clauses (iii)(x) and (z), any net cash proceeds
from an Equity Offering to the extent used to redeem the Notes).
 
    Notwithstanding the foregoing, the provisions set forth in the immediately
preceding paragraph do not prohibit: (1) the payment of any dividend within 60
days after the date of declaration of such dividend if the dividend would have
been permitted on the date of declaration; (2) if no Default or Event of Default
shall have occurred and be continuing, the acquisition, redemption, repurchase
or retirement of any shares of Capital Stock of the Company, either (i) solely
in exchange for shares of Qualified Capital Stock of the Company or (ii) through
the application of net proceeds of a substantially concurrent sale for cash
(other than to a Subsidiary of the Company) of shares of Qualified Capital Stock
of the Company; (3) if no Default or Event of Default shall have occurred and be
continuing, the acquisition of any Indebtedness of the Company that is
subordinate or junior in right of payment to the Notes either (i) solely in
exchange for shares of Qualified Capital Stock of the Company, or (ii) through
the application of net proceeds of a substantially concurrent sale for cash
(other than to a Subsidiary of the Company) of (A) shares of Qualified Capital
Stock of the Company or (B) Refinancing Indebtedness; (4) so long as no Default
or Event of Default shall have occurred and be continuing, repurchases by the
Company of Common Stock of the Company from employees, officers or directors of
the Company or any of its Subsidiaries or their authorized representatives upon
the death, disability or termination of employment of such officers, directors
and employees, in an aggregate amount not to exceed $1,000,000 in any calendar
year and $5,000,000 in the aggregate, in each case plus the aggregate cash
proceeds from any reissuance during such calendar year of Common Stock by the
Company to employees, officers or directors of the Company and
 
                                       76
<PAGE>
its Subsidiaries plus the aggregate cash proceeds from any payments on life
insurance policies in which the Company or its Subsidiaries is the beneficiary
with respect to any employees, officers or directors of the Company and its
Subsidiaries which proceeds are used to purchase the Common Stock of the Company
held by any such employees, officers or directors; (5) if no Default or Event of
Default shall have occurred and be continuing, the redemption at stated maturity

be continuing, the repurchase by the Company of the warrants issued in
connection with the Warrant Agreement upon the exercise of the put rights
contained in such Warrant Agreement by the holders of such warrants; and (7)
repurchases of Capital Stock deemed to occur upon the exercise of stock options
if such Capital Stock represents a portion of the exercise price thereof. In
determining the aggregate amount of Restricted Payments made subsequent to the
Issue Date in accordance with clause (iii) of the immediately preceding
paragraph, amounts expended pursuant to clauses (1), (2)(ii), (3)(ii)(A), (4),
(5), (6) and, to the extent included in clause (iii)(x) or (z) of the preceding
paragraph, (7) shall be included in such calculation.
 
    Not later than the date of making any Restricted Payment, the Company shall
deliver to the Trustee an officers' certificate stating that such Restricted
Payment complies with the Indenture and setting forth in reasonable detail the
basis upon which the required calculations were computed, which calculations may
be based upon the Company's latest available internal quarterly financial
statements.
 
    LIMITATION ON ASSET SALES.  The Company will not, and will not permit any of
its Restricted Subsidiaries to, consummate an Asset Sale unless (i) the Company
or the applicable Restricted Subsidiary, as the case may be, receives
consideration at the time of such Asset Sale at least equal to the fair market
value of the assets sold or otherwise disposed of (as determined in good faith
by the Company's Board of Directors), (ii) at least 75% of the consideration
received by the Company or the Restricted Subsidiary, as the case may be, from
such Asset Sale shall be in the form of cash or Cash Equivalents and is received
at the time of such disposition (the fair market value of Replacement Assets (as
defined below) received by the Company or any Restricted Subsidiary, as the case
may be, from such Asset Sale shall be considered cash or Cash Equivalents for
purposes of this covenant); and (iii) upon the consummation of an Asset Sale,
the Company shall apply, or cause such Restricted Subsidiary to apply, the Net
Cash Proceeds relating to such Asset Sale within 270 days of receipt thereof
either (A) to prepay any Senior Debt and, in the case of any Senior Debt under
any revolving credit facility, effect a permanent reduction in the availability
under such revolving credit facility, (B) to make an investment in properties
and assets that replace the properties and assets that were the subject of such
Asset Sale or in properties and assets that will be used in the business of the
Company and its Subsidiaries as existing on the Issue Date or in any businesses
which are similar or related to the contract packaging and manufacturing
businesses ("Replacement Assets"), or (C) a combination of prepayment and
investment permitted by the foregoing clauses (iii)(A) and (iii)(B). On the
271st day after an Asset Sale or such earlier date, if any, as the Board of
Directors of the Company or of such Restricted Subsidiary determines not to
apply the Net Cash Proceeds relating to such Asset Sale as set forth in clauses
(iii)(A), (iii)(B) and (iii)(C) of the next preceding sentence (each, a "Net
Proceeds Offer Trigger Date"), an amount equal to such aggregate amount of Net
Cash Proceeds which have not been applied on or before such Net Proceeds Offer
Trigger Date as permitted in clauses (iii)(A), (iii)(B) and (iii)(C) of the next
preceding sentence (each a "Net Proceeds Offer Amount") shall be applied by the
Company or such Restricted Subsidiary to make an offer to purchase (the "Net
Proceeds Offer") on a date (the "Net Proceeds Offer Payment Date") within 45
days following the applicable Net Proceeds Offer Trigger Date, from all Holders
on a PRO RATA basis, that amount of Notes equal to the Net Proceeds Offer Amount
at a price equal to 100% of the principal amount of the Notes to be purchased,
plus accrued and unpaid interest thereon, if any, to the date of purchase;
PROVIDED, HOWEVER, that if at any time any consideration other than Cash or Cash
Equivalents received by the Company or any Restricted Subsidiary of the Company,
as the case may be, in connection with any Asset Sale is converted into or sold
or otherwise disposed of for cash (other than interest received with respect to
any such non-cash consideration), then such conversion or disposition shall be
deemed to constitute an Asset Sale hereunder and the
 
                                       77
<PAGE>
Net Cash Proceeds thereof shall be applied in accordance with this covenant. A
transfer of assets by the Company to a Wholly-Owned Restricted Subsidiary or by
a Restricted Subsidiary to the Company or to another Wholly-Owned Restricted
Subsidiary will not be deemed to be an Asset Sale. The Company may defer the Net
Proceeds Offer until there is an aggregate unutilized Net Proceeds Offer Amount
equal to or in excess of $5,000,000 resulting from one or more Asset Sales (at
which time, the entire unutilized Net Proceeds Offer Amount, and not just the
amount in excess of $5,000,000, shall be applied as required pursuant to this
paragraph).
 
    In the event of the transfer of substantially all (but not all) of the
property and assets of the Company and its Restricted Subsidiaries as an
entirety to a Person in a transaction permitted under "--Merger, Consolidation
and Sale of Assets," the successor corporation shall be deemed to have sold the
properties and assets of the Company and its Restricted Subsidiaries not so
transferred for purposes of this covenant, and shall comply with the provisions
of this covenant with respect to such deemed sale as if it were an Asset Sale.
In addition, the fair market value of such properties and assets of the Company
or its Restricted Subsidiaries deemed to be sold pursuant to this paragraph less
the fair market value of all liabilities of such Person related to such property
and assets not transferred shall be deemed to be Net Cash Proceeds for purposes
of this covenant.
 
    Each Net Proceeds Offer will be mailed to the record Holders as determined
on a date shown on the register of Holders within 25 days following the Net
Proceeds Offer Trigger Date, with a copy to the Trustee, and shall comply with
the procedures set forth in the Indenture. Upon receiving notice of the Net
Proceeds Offer, Holders may elect to tender their Notes in whole or in part in
integral multiples of $1,000 in exchange for cash. To the extent Holders
properly tender Notes in an amount exceeding the Net Proceeds Offer Amount,
Notes of tendering Holders will be purchased on a PRO RATA basis (based on
amounts tendered), unless otherwise required by law or any applicable exchange
rules. A Net Proceeds Offer shall remain open for a period of 20 business days
or such longer period as may be required by law.
 
    The Company will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with the
repurchase of Notes pursuant to a Net Proceeds Offer. To the extent that the
provisions of any securities laws or regulations or any applicable exchange
regulations conflict with the "Asset Sale" provisions of the Indenture, the
Company shall comply with the applicable securities laws and regulations and
exchange regulations and shall not be deemed to have breached its obligations
under the "Asset Sale" provisions of the Indenture by virtue thereof. The
agreements governing certain outstanding Senior Debt of the Company may require
that the Company and its Subsidiaries apply all proceeds from asset sales to
repay in full outstanding obligations under such Senior Debt prior to the
application of such proceeds to repurchase outstanding Notes.
 
    LIMITATION ON DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING
SUBSIDIARIES.  The Company will not, and will not cause or permit any of its
Restricted Subsidiaries to, directly or indirectly, create or otherwise
 
cause or permit to exist or become effective any encumbrance or restriction on
the ability of any Restricted Subsidiary of the Company to (a) pay dividends or
make any other distributions on or in respect of its Capital Stock; (b) make
loans or advances or to pay any Indebtedness or other obligation owed to the
Company or any other Restricted Subsidiary of the Company; or (c) transfer any
of its property or assets to the Company or any other Restricted Subsidiary of
the Company, except for such encumbrances or restrictions existing under or by
reason of: (1) applicable law; (2) the Indenture, the Notes and the Guarantees;
(3) customary non-assignment provisions of any contract or any lease governing a
leasehold interest of any Restricted Subsidiary of the Company; (4) any
instrument governing Acquired Indebtedness, which encumbrance or restriction is
not applicable to any Person, or the properties or assets of any Person, other
than the Person or the properties or assets of the Person so acquired; (5)
agreements existing
 
                                       78
<PAGE>
on the Issue Date (including the Credit Agreement) to the extent and in the
manner such agreements are in effect on the Issue Date; (6) any restriction or
encumbrance contained in contracts for sale of assets permitted by the Indenture
in respect of the assets being sold pursuant to such contracts pending the close
of such sale, which encumbrance or restriction is not applicable to any asset
other than the asset being sold pursuant to such contract; (7) Purchase Money
Obligations for property acquired in the ordinary course of business that impose
restrictions of the nature described in clause (c) above on the property so
acquired; (8) restrictions of the nature described in (c) above on the transfer
of assets subject to any Lien permitted under the Indenture imposed by the
holder of such Lien; or (9) an agreement governing Indebtedness incurred to
Refinance the Indebtedness issued, assumed or incurred pursuant to an agreement
referred to in clause (2), (4) or (5) above; PROVIDED, HOWEVER, that the
provisions relating to such encumbrance or restriction contained in any such
Indebtedness are no less favorable to the Company in any material respect as
determined by the Board of Directors of the Company in their reasonable and good
faith judgment than the provisions relating to such encumbrance or restriction
contained in agreements referred to in such clause (2), (4) or (5).
 
    LIMITATION ON PREFERRED STOCK OF RESTRICTED SUBSIDIARIES.  The Company will
not permit any of its Restricted Subsidiaries to issue any Preferred Stock
(other than to the Company or to a Wholly-Owned Restricted Subsidiary of the
Company) or permit any Person (other than the Company or a Wholly-Owned
Restricted Subsidiary of the Company) to own any Preferred Stock of any
Restricted Subsidiary of the Company unless at the time of such issuance such
Restricted Subsidiary would be entitled to create, incur or assume Indebtedness
pursuant to the covenant described under "--Limitation on Incurrence of
Additional Indebtedness" in the aggregate amount equal to the aggregate
liquidation value, plus any accrued and unpaid dividends, of the Preferred Stock
to be issued. Notwithstanding the foregoing, nothing contained in such covenant
will prohibit the ownership of Preferred Stock issued by a Person prior to the
time (a) such Person becomes a Restricted Subsidiary of the Company, (b) such
Person merges with or into a Restricted Subsidiary of the Company or (c) a
Subsidiary of the Company merges with or into such Person; PROVIDED that such
Preferred Stock was not issued by such Person in anticipation of a transaction
contemplated by any of clauses (a), (b) or (c) above.
 
    LIMITATION ON LIENS.  The Company will not, and will not cause or permit any
of its Restricted Subsidiaries to, directly or indirectly, create, incur, assume
or permit or suffer to exist any Liens of any kind against or upon any property
or assets of the Company or any of its Restricted Subsidiaries whether owned on
the Issue Date or acquired after the Issue Date, or any proceeds therefrom, or
assign or otherwise convey any right to receive income or profits therefrom
unless (i) in the case of Liens securing Indebtedness that is expressly
subordinate or junior in right of payment to the Notes or any Guarantee, the
Notes and such Guarantee, as the case may be, are secured by a Lien on such
property, assets or proceeds that is senior in priority to such Liens and (ii)
in all other cases, the Notes and the Guarantees are equally and ratably
secured, except for (A) Liens existing as of the Issue Date to the extent and in
the manner such Liens are in effect on the Issue Date; (B) Liens securing Senior
Debt and Liens securing Guarantor Senior Debt; (C) Liens securing the Notes and
the Guarantees; (D) Liens of the Company or a Wholly-Owned Restricted Subsidiary
of the Company on assets of any Subsidiary of the Company; (E) Liens securing
Refinancing Indebtedness which is incurred to Refinance any Indebtedness which
has been secured by a Lien permitted under the Indenture and which has been
incurred in accordance with the provisions of the Indenture; PROVIDED, HOWEVER,
that such Liens (A) are no less favorable to the Holders and are not more
favorable to the lienholders with respect to such Liens than the Liens in
respect of the Indebtedness being Refinanced and (B) do not extend to or cover
any property or assets of the Company or any of its Restricted Subsidiaries not
securing the Indebtedness so Refinanced; and (F) Permitted Liens.
 
    PROHIBITION ON INCURRENCE OF SENIOR SUBORDINATED DEBT.  The Company will
not, and will not permit any Guarantor to, incur or suffer to exist Indebtedness
that is senior in right of payment to the Notes or any Guarantee, as the case
may be, and subordinate in right of payment to any other Indebtedness of the
Company or such Guarantor, as the case may be.
 
                                       79
<PAGE>
    MERGER, CONSOLIDATION AND SALE OF ASSETS.  The Company will not, in a single
transaction or series of related transactions, consolidate or merge with or into
any Person, or sell, assign, transfer, lease, convey or otherwise dispose of (or
cause or permit any Restricted Subsidiary of the Company to sell, assign,
transfer, lease, convey or otherwise dispose of) all or substantially all of the
Company's assets (determined on a consolidated basis for the Company and the
Company's Restricted Subsidiaries) whether as an entirety or substantially as an
entirety to any Person unless: (i) either (1) the Company shall be the surviving
or continuing corporation or (2) the Person (if other than the Company) formed
by such consolidation or into which the Company is merged or the Person which
acquires by sale, assignment, transfer, lease, conveyance or other disposition
the properties and assets of the Company and of the Company's Restricted
Subsidiaries substantially as an entirety (the "Surviving Entity") (x) shall be
a corporation organized and validly existing under the laws of the United States
or any State thereof or the District of Columbia and (y) shall expressly assume,
by supplemental indenture (in form and substance satisfactory to the Trustee),
executed and delivered to the Trustee, the due and punctual payment of the
principal of, and premium, if any, and interest on all of the Notes and the
performance of every covenant of the Notes, the Indenture and the Registration
Rights Agreement on the part of the Company to be performed or observed; (ii)
immediately after giving effect to such transaction and the assumption
contemplated by clause (i)(2)(y) above (including giving effect to any
Indebtedness and Acquired Indebtedness incurred or anticipated to be incurred in
connection with or in respect of such transaction), the Company or such
Surviving Entity, as the case may be, (1) shall have a Consolidated Net Worth
equal to or greater than 90% of the Consolidated Net Worth of the Company
immediately prior to such transaction and (2) shall be able to incur at least
$1.00 of additional Indebtedness (other than Permitted Indebtedness) pursuant to
the "Limitation on Incurrence of Additional Indebtedness" covenant; (iii)
immediately before and immediately after giving effect to such transaction and
the assumption contemplated by clause (i)(2)(y) above (including, without
limitation, giving effect to any Indebtedness and Acquired Indebtedness incurred
or anticipated to be incurred and any Lien granted in connection with or in
respect of the transaction), no Default or Event of Default shall have occurred
and be continuing; and (iv) the Company or the Surviving Entity shall have
delivered to the Trustee an officers' certificate and an opinion of counsel,
each stating that such consolidation, merger, sale, assignment, transfer, lease,
conveyance or other disposition, and if a supplemental indenture is required in
connection with such transaction, such supplemental indenture, comply with the
applicable provisions of the Indenture and that all conditions precedent in the
Indenture relating to such transaction have been satisfied.
 
    For purposes of the foregoing, the transfer (by lease, assignment, sale or
otherwise, in a single transaction or series of transactions) of all or
substantially all of the properties or assets of one or more Restricted
Subsidiaries of the Company, the Capital Stock of which constitutes all or
substantially all of the properties and assets of the Company, shall be deemed
to be the transfer of all or substantially all of the properties and assets of
the Company.
 
    The Indenture will provide that upon any consolidation, combination or
merger or any transfer of all or substantially all of the assets of the Company
in accordance with the foregoing, in which the Company is not the continuing
corporation, the Surviving Entity formed by such consolidation or into which the
Company is merged or to which such conveyance, lease or transfer is made shall
succeed to, and be substituted for, and may exercise every right and power of,
the Company under the Indenture and the Notes with the same effect as if such
surviving entity had been named as such.
 
    Each Guarantor (other than any Guarantor whose Guarantee is to be released
in accordance with the terms of the Guarantee and the Indenture in connection
with any transaction complying with the provisions of "--Limitation on Asset
Sales") will not, and the Company will not cause or permit any Guarantor to,
consolidate with or merge with or into any Person other than the Company or any
other Guarantor unless: (i) the entity formed by or surviving any such
consolidation or merger (if other than the Guarantor) or to which such sale,
lease, conveyance or other disposition shall have been made is a corporation
organized and existing under the laws of the United States or any State thereof
or the District
 
                                       80
<PAGE>
of Columbia; (ii) such entity assumes by supplemental indenture all of the
obligations of the Guarantor on the Guarantee; and (iii) immediately after
giving effect to such transaction, no Default or Event of Default shall have
occurred and be continuing. Any merger or consolidation of a Guarantor with and
into the Company (with the Company being the Surviving Entity) or another
Guarantor that is a Wholly-Owned Restricted Subsidiary of the Company need only
comply with clause (iv) of the first paragraph of this covenant.
 
    LIMITATIONS ON TRANSACTIONS WITH AFFILIATES.  (a) The Company will not, and
will not permit any of its Restricted Subsidiaries to, directly or indirectly,
enter into or permit to exist any transaction or series of related transactions
(including, without limitation, the purchase, sale, lease or exchange of any
property or the rendering of any service) with, or for the benefit of, any of
its Affiliates (each an "Affiliate Transaction"), other than (x) Affiliate
Transactions permitted under paragraph (b) below and (y) Affiliate Transactions
on terms that are not less favorable than those that might reasonably have been
obtained in a comparable transaction at such time on an arm's-length basis from
a Person that is not an Affiliate of the Company or such Restricted Subsidiary.
All Affiliate Transactions (and each series of related Affiliate Transactions
which are similar or part of a common plan) involving aggregate payments or
other property with a fair market value in excess of $500,000 shall be approved
by the Board of Directors of the Company or such Restricted Subsidiary, as the
case may be, such approval to be evidenced by a Board Resolution stating that
such Board of Directors has determined that such transaction complies with the
foregoing provisions. If the Company or any Restricted Subsidiary of the Company
enters into an Affiliate Transaction (or a series of related Affiliate
Transactions related to a common plan) that involves an aggregate fair market
value of more than $5,000,000, the Company or such Restricted Subsidiary, as the
case may be, shall, prior to the consummation thereof, obtain a favorable
opinion as to the fairness of such transaction or series of related transactions
to the Company or the relevant Restricted Subsidiary, as the case may be, from a
financial point of view, from an Independent Financial Advisor and file the same
with the Trustee.
 
    (b) The restrictions set forth in paragraph (a) shall not apply to (i)
reasonable fees and compensation paid to and indemnity provided on behalf of,
officers, directors or employees, agents or consultants of the Company or any
Restricted Subsidiary of the Company as determined in good faith by the
Company's Board of Directors or senior management; (ii) transactions exclusively
between or among the Company and any of its Wholly-Owned Restricted Subsidiaries
or exclusively between or among such Wholly-Owned Restricted Subsidiaries,
provided such transactions are not otherwise prohibited by the Indenture; (iii)
any agreement as in effect as of the Issue Date or any amendment thereto or any
transaction contemplated thereby (including pursuant to any amendment thereto)
in any replacement agreement thereto so long as any such amendment or
replacement agreement is not more disadvantageous to the Company or its
Restricted Subsidiaries, as the case may be, in any material respect than the
original agreement as in effect on the Issue Date; (iv) Restricted Payments
permitted by the Indenture; (v) any issuance of securities or other payments,
awards or grants in cash, securities or otherwise pursuant to, or the funding
of, employment arrangements, stock options and stock ownership plans of the
Company entered into in the ordinary course of business and approved by the
Board of Directors; (vi) fees and related expenses paid pursuant to the
Management Agreement; (vii) loans and advances, or guarantees of loans of
third-parties, to employees and officers of the Company and its Restricted
Subsidiaries in the ordinary course of business for BONA FIDE business purposes
not in excess of $2,000,000 at any time outstanding; (viii) indemnification
agreements provided for the benefit of the Company or any Restricted Subsidiary
of the Company from officers, directors or employees of the Company or any
Restricted Subsidiary; (ix) all leases for equipment and real property used by
the Company which are between the Company or any Restricted Subsidiary of the
Company and either of Nancy Lim, Walter Lim or Howard Lim, and any Affiliate
thereof, (A) entered into in the ordinary course of business, on terms no less
favorable to the Company than could be obtained from a third party in an
arm's-length transaction and approved by the Board of Directors or (B) contained
in agreements in existence as of the Issue Date; and (x) the sale of inventory
in the ordinary course of
 
                                       81
<PAGE>
business on customary terms no less favorable to the Company and its
Subsidiaries than could be obtained from a third party in an arm's-length
transaction.
 
    ADDITIONAL SUBSIDIARY GUARANTEES.  If the Company or any of its Restricted
Subsidiaries transfers or causes to be transferred, in one transaction or a
series of related transactions, any property to any Restricted Subsidiary (other
than a Foreign Subsidiary) that is not a Guarantor, or if the Company or any of
its Restricted Subsidiaries shall organize, acquire or otherwise invest in
another Restricted Subsidiary (other than a Foreign Subsidiary) in each case
having total assets with a book value in excess of $500,000, then such
transferee or acquired or other Restricted Subsidiary (other than a Foreign
Subsidiary) and, in the case of a transferee or acquired or other Restricted
Subsidiary (other than a Foreign Subsidiary) that does not have total assets
with a book value in excess of $500,000, when such transferee or acquired or
other Restricted Subsidiary (other than a Foreign Subsidiary) obtains assets
with a book value in excess of $500,000 shall (i) execute and deliver to the
Trustee a supplemental indenture in form reasonably satisfactory to the Trustee
pursuant to which such Restricted Subsidiary shall guarantee on a full,
unconditional, joint and several and unsecured senior subordinated basis all of
the Company's obligations under the Notes and the Indenture on the terms set
forth in the Indenture and (ii) deliver to the Trustee an opinion of counsel
that such supplemental indenture has been duly authorized, executed and
delivered by such Restricted Subsidiary and constitutes a legal, valid, binding
and enforceable obligation of such Restricted Subsidiary (with customary
exceptions). Thereafter, such Restricted Subsidiary shall be a Guarantor for all
purposes of the Indenture.
 
    CONDUCT OF BUSINESS.  The Company and its Restricted Subsidiaries will not
engage, to any material extent, in any businesses which are not the same,
similar or related to the contract packaging and manufacturing businesses.
 
    REPORTS TO HOLDERS.  The Indenture will provide that the Company will
deliver to the Trustee within 15 days after the filing of the same with the
Commission, copies of the quarterly and annual reports and of the information,
documents and other reports, if any, which the Company is required to file with
the Commission pursuant to Section 13 or 15(d) of the Exchange Act. The
Indenture further provides that, notwithstanding that the Company may not be
subject to the reporting requirements of Section 13 or 15(d) of the Exchange
Act, the Company will, beginning on the earlier of the date the Registration
Statement of which this Prospectus is a part becomes effective and 180 days
after the Issue Date, file with the Commission, to the extent permitted, and
provide the Trustee and the Holders with such annual reports and such
information, documents and other reports specified in Sections 13 and 15(d) of
the Exchange Act within 15 days after the same would be required to be filed
with the Commission if the Company were subject to such reporting requirements.
The Company will also comply with the other provisions of TIA Section 314(a). So
long as any of the Notes remain outstanding, the Company has agreed to make
available to any prospective purchaser of the Notes or the beneficial owner of
the Notes in connection with any sale thereof the information required by Rule
144A(d)(4) under the Securities Act.
 
EVENTS OF DEFAULT
 
    The following events are defined in the Indenture as "Events of Default":
 
        (i) the failure to pay interest on any Notes when the same becomes due
    and payable and the default continues for a period of 30 days (whether or
    not such payment shall be prohibited by the subordination provisions of the
    Indenture);
 
        (ii) the failure to pay the principal on any Notes, when such principal
    becomes due and payable, at maturity, upon redemption or otherwise
    (including the failure to make a payment to purchase Notes tendered pursuant
    to a Change of Control Offer or a Net Proceeds Offer) (whether or not such
    payment shall be prohibited by the subordination provisions of the
    Indenture);
 
        (iii) a default in the observance or performance of any other covenant
    or agreement contained in the Indenture which default continues for a period
    of 30 days after the Company receives written
 
                                       82
<PAGE>
    notice specifying the default (and demanding that such default be remedied)
    from the Trustee or the Holders of at least 25% of the outstanding principal
    amount of the Notes (except in the case of a default with respect to the
    "Merger, Consolidation and Sale of Assets" covenant, which will constitute
    an Event of Default with such notice requirement but without such passage of
    time requirement);
 
        (iv) the failure to pay at final maturity (giving effect to any
    applicable grace periods and any extensions thereof) the principal amount of
    any Indebtedness of the Company or any Restricted Subsidiary of the Company
    and such failure continues for a period of 20 days or more, or the
    acceleration of the final stated maturity of any such Indebtedness (which
    acceleration is not rescinded, annulled or otherwise cured within 20 days of
    receipt by the Company or such Restricted Subsidiary of notice of any such
    acceleration) if the aggregate principal amount of such Indebtedness,
    together with the principal amount of any other such Indebtedness in default
    for failure to pay principal at final maturity or which has been
    accelerated, in each case with respect to which the 20-day period described
    above has passed, aggregates $5,000,000 or more at any time;
 
        (v) one or more judgments in an aggregate amount in excess of $5,000,000
    (excluding judgments to the extent covered by insurance by a reputable
    insurer as to which the insurer has acknowledged coverage) shall have been
    rendered against the Company or any of its Restricted Subsidiaries and such
    judgments remain undischarged, unpaid or unstayed for a period of 60 days
    after such judgment or judgments become final and non-appealable;
 
        (vi) certain events of bankruptcy affecting the Company or any of its
    Significant Subsidiaries; or
 
        (vii) any of the Guarantees of a Significant Subsidiary ceases to be in
    full force and effect or any of the Guarantees of a Significant Subsidiary
    is declared to be null and void and unenforceable or any of the Guarantees
    is found to be invalid or any of the Guarantors which is a Significant
    Subsidiary denies its liability under its Guarantee (other than by reason of
    release of a Guarantor in accordance with the terms of the Indenture).
 
    If an Event of Default (other than an Event of Default specified in clause
(vi) above) shall occur and be continuing, the Trustee or the Holders of at
least 25% in principal amount of outstanding Notes may declare the principal of
and accrued interest on all the Notes to be due and payable by notice in writing
to the Company and the Trustee specifying the respective Event of Default and
that it is a "notice of acceleration" (the "Acceleration Notice"), and the same
(i) shall become immediately due and payable or (ii) if there are any amounts
outstanding under the Credit Agreement, shall become immediately due and payable
upon the first to occur of an acceleration under the Credit Agreement or 5
business days after receipt by the Company and the Representative under the
Credit Agreement of such Acceleration Notice. If an Event of Default specified
in clause (vi) above occurs and is continuing, then all unpaid principal of, and
premium, if any, and accrued and unpaid interest on all of the outstanding Notes
shall IPSO FACTO become and be immediately due and payable without any
declaration or other act on the part of the Trustee or any Holder.
 
    The Indenture will provide that, at any time after a declaration of
acceleration with respect to the Notes as described in the preceding paragraph,
the Holders of a majority in principal amount of the Notes may rescind and
cancel such declaration and its consequences (i) if the rescission would not
conflict with any judgment or decree, (ii) if all existing Events of Default
have been cured or waived except nonpayment of principal or interest that has
become due solely because of the acceleration, (iii) to the extent the payment
of such interest is lawful, interest on overdue installments of interest and
overdue principal, which has become due otherwise than by such declaration of
acceleration, has been paid, (iv) if the Company has paid the Trustee its
reasonable compensation and reimbursed the Trustee for its expenses,
disbursements and advances and (v) in the event of the cure or waiver of an
Event of Default of the type described in clause (vi) of the description above
of Events of Default, the Trustee shall have received an officers' certificate
and an opinion of counsel that such Event of Default has been cured or waived.
No such rescission shall affect any subsequent Default or impair any right
consequent thereto.
 
                                       83
<PAGE>
    The Holders of a majority in principal amount of the Notes may waive any
existing Default or Event of Default under the Indenture, and its consequences,
except a default in the payment of the principal of or interest on any Notes or
except as otherwise prohibited by the TIA.
 
    Holders of the Notes may not enforce the Indenture or the Notes except as
provided in the Indenture and under the TIA. Subject to the provisions of the
Indenture relating to the duties of the Trustee, the Trustee is under no
obligation to exercise any of its rights or powers under the Indenture at the
request, order or direction of any of the Holders, unless such Holders have
offered to the Trustee reasonable indemnity. Subject to all provisions of the
Indenture and applicable law, the Holders of a majority in aggregate principal
amount of the then outstanding Notes have the right to direct the time, method
and place of conducting any proceeding for any remedy available to the Trustee
or exercising any trust or power conferred on the Trustee.
 
    Under the Indenture, the Company is required to provide an officers'
certificate to the Trustee promptly upon any such officer obtaining knowledge of
any Default or Event of Default (provided that such officers shall provide such
certification at least annually whether or not they know of any Default or Event
of Default) that has occurred and, if applicable, describe such Default or Event
of Default and the status thereof.
 
LEGAL DEFEASANCE AND COVENANT DEFEASANCE
 
    The Company may, at its option and at any time, elect to have its
obligations and the obligations of the Guarantors discharged with respect to the
outstanding Notes ("Legal Defeasance"). Such Legal Defeasance means that the
Company shall be deemed to have paid and discharged the entire indebtedness
represented by the outstanding Notes, except for (i) the rights of Holders to
receive payments in respect of the principal of, premium, if any, and interest
on the Notes when such payments are due, (ii) the Company's obligations with
respect to the Notes concerning issuing temporary Notes, registration of Notes,
mutilated, destroyed, lost or stolen Notes and the maintenance of an office or
agency for payments, (iii) the rights, powers, trust, duties and immunities of
the Trustee and the Company's obligations in connection therewith and (iv) the
Legal Defeasance provisions of the Indenture. In addition, the Company may, at
its option and at any time, elect to have the obligations of the Company
released with respect to certain covenants that are described in the Indenture
("Covenant Defeasance") and thereafter any omission to comply with such
obligations shall not constitute a Default or Event of Default with respect to
the Notes. In the event Covenant Defeasance occurs, certain events (not
including non-payment, bankruptcy, receivership, reorganization and insolvency
events) described under "Events of Default" will no longer constitute an Event
of Default with respect to the Notes.
 
    In order to exercise either Legal Defeasance or Covenant Defeasance, (i) the
Company must irrevocably deposit with the Trustee, in trust, for the benefit of
the Holders cash in U.S. dollars, non-callable U.S. government obligations, or a
combination thereof, in such amounts as will be sufficient, in the opinion of a
nationally recognized firm of independent public accountants, to pay the
principal of, premium, if any, and interest on the Notes on the stated date for
payment thereof or on the applicable redemption date, as the case may be; (ii)
in the case of Legal Defeasance, the Company shall have delivered to the Trustee
an opinion of counsel in the United States reasonably acceptable to the Trustee
confirming that (A) the Company has received from, or there has been published
by, the Internal Revenue Service a ruling or (B) since the date of the
Indenture, there has been a change in the applicable federal income tax law, in
either case to the effect that, and based thereon such opinion of counsel shall
confirm that, the Holders will not recognize income, gain or loss for federal
income tax purposes as a result of such Legal Defeasance and will be subject to
federal income tax on the same amounts, in the same manner and at the same times
as would have been the case if such Legal Defeasance had not occurred; (iii) in
the case of Covenant Defeasance, the Company shall have delivered to the Trustee
an opinion of counsel in the United States reasonably acceptable to the Trustee
confirming that the Holders will not recognize income, gain or loss for federal
income tax purposes as a result of such Covenant Defeasance and will be subject
to
 
                                       84
<PAGE>
federal income tax on the same amounts, in the same manner and at the same times
as would have been the case if such Covenant Defeasance had not occurred; (iv)
no Default or Event of Default shall have occurred and be continuing on the date
of such deposit or insofar as Events of Default from bankruptcy or insolvency
events are concerned, at any time in the period ending on the 91st day after the
date of deposit; (v) such Legal Defeasance or Covenant Defeasance shall not
result in a breach or violation of, or constitute a default under the Indenture
or any other material agreement or instrument to which the Company or any of its
Subsidiaries is a party or by which the Company or any of its Subsidiaries is
bound; (vi) the Company shall have delivered to the Trustee an officers'
certificate stating that the deposit was not made by the Company with the intent
of preferring the Holders over any other creditors of the Company or with the
intent of defeating, hindering, delaying or defrauding any other creditors of
the Company or others; (vii) the Company shall have delivered to the Trustee an
officers' certificate and an opinion of counsel, each stating that all
conditions precedent (other than, in the case of such legal opinion, paragraph
(vi) as to which such counsel need express no opinion) provided for or relating
to the Legal Defeasance or the Covenant Defeasance have been complied with;
(viii) the Company shall have delivered to the Trustee an opinion of counsel to
the effect that (A) the trust funds will not be subject to any rights of holders
of Senior Debt, including, without limitation, those arising under the Indenture
and (B) after the 91st day following the deposit, the trust funds will not be
subject to the effect of any applicable bankruptcy, insolvency, reorganization
or similar laws affecting creditors' rights generally; and (ix) certain other
customary conditions precedent are satisfied.
 
SATISFACTION AND DISCHARGE
 
    The Indenture will be discharged and will cease to be of further effect
(except as to surviving rights or registration of transfer or exchange of the
Notes, as expressly provided for in the Indenture) as to all outstanding Notes
when (i) either (a) all the Notes theretofore authenticated and delivered
(except lost, stolen or destroyed Notes which have been replaced or paid and
Notes for whose payment money has theretofore been deposited in trust or
segregated and held in trust by the Company and thereafter repaid to the Company
or discharged from such trust) have been delivered to the Trustee for
cancellation or (b) all Notes not theretofore delivered to the Trustee for
cancellation have become due and payable and the Company has irrevocably
deposited or caused to be deposited with the Trustee funds in an amount
sufficient to pay and discharge the entire Indebtedness on the Notes not
theretofore delivered to the Trustee for cancellation, for principal of,
premium, if any, and interest on the Notes to the date of deposit together with
irrevocable instructions from the Company directing the Trustee to apply such
funds to the payment thereof at maturity or redemption, as the case may be; (ii)
the Company has paid all other sums payable under the Indenture by the Company;
and (iii) the Company has delivered to the Trustee an officers' certificate and
an opinion of counsel stating that all conditions precedent under the Indenture
relating to the satisfaction and discharge of the Indenture have been complied
with.
 
MODIFICATION OF THE INDENTURE
 
    From time to time, the Company, the Guarantors and the Trustee, without the
consent of the Holders, may amend the Indenture for certain specified purposes,
including curing ambiguities, defects or inconsistencies, so long as such change
does not, in the opinion of the Trustee, adversely affect the rights of any of
the Holders in any material respect. In formulating its opinion on such matters,
the Trustee will be entitled to rely on such evidence as it deems appropriate,
including, without limitation, solely on an opinion of counsel. Other
modifications and amendments of the Indenture may be made with the consent of
the Holders of a majority in principal amount of the then outstanding Notes
issued under the Indenture, except that, without the consent of each Holder
affected thereby, no amendment may: (i) reduce the amount of Notes whose Holders
must consent to an amendment; (ii) reduce the rate of or change or have the
effect of changing the time for payment of interest, including defaulted
interest, on any Notes; (iii) reduce the principal of or change or have the
effect of changing the fixed maturity of any Notes, or change the date on which
any Notes may be subject to redemption or repurchase, or reduce the redemption
or repurchase price therefor; (iv) make any Notes payable in money other than
that stated in
 
                                       85
<PAGE>
the Notes; (v) make any change in provisions of the Indenture protecting the
right of each Holder to receive payment of principal of and interest on such
Note on or after the due date thereof or to bring suit to enforce such payment,
or permitting Holders of a majority in principal amount of Notes to waive
Defaults or Events of Default; (vi) amend, change or modify in any material
respect the obligation of the Company to make and consummate a Change of Control
Offer after the occurrence of an event which constitutes a Change of Control or
make and consummate a Net Proceeds Offer with respect to any Asset Sale that has
been consummated or modify any of the provisions or definitions with respect
thereto; (vii) modify or change any provision of the Indenture or the related
definitions affecting the subordination or ranking of the Notes or any Guarantee
in a manner which adversely affects the Holders; or (viii) release any Guarantor
from any of its obligations under its Guarantee or the Indenture otherwise than
in accordance with the terms of the Indenture.
 
GOVERNING LAW
 
    The Indenture will provide that it, the Notes and the Guarantees will be
governed by, and construed in accordance with, the laws of the State of New York
but without giving effect to applicable principles of conflicts of law to the
extent that the application of the law of another jurisdiction would be required
thereby.
 
THE TRUSTEE
 
    The Indenture will provide that, except during the continuance of an Event
of Default, the Trustee will perform only such duties as are specifically set
forth in the Indenture. During the existence of an Event of Default, the Trustee
will exercise such rights and powers vested in it by the Indenture, and use the
same degree of care and skill in its exercise as a prudent man would exercise or
use under the circumstances in the conduct of his own affairs.
 
    The Indenture and the provisions of the TIA contain certain limitations on
the rights of the Trustee, should it become a creditor of the Company, to obtain
payments of claims in certain cases or to realize on certain property received
in respect of any such claim as security or otherwise. Subject to the TIA, the
Trustee will be permitted to engage in other transactions; PROVIDED that if the
Trustee acquires any conflicting interest as described in the TIA, it must
eliminate such conflict or resign.

of the foregoing, for purposes of this definition, "Consolidated EBITDA" and
"Consolidated Fixed Charges" shall be calculated after giving effect on a PRO
FORMA basis for the period of such calculation to (i) the incurrence or
repayment of any Indebtedness of such Person or any of its Restricted
Subsidiaries (and the application of the proceeds thereof) giving rise to the
need to make such calculation and any incurrence or repayment of other
Indebtedness (and the
 
                                       88
<PAGE>
application of the proceeds thereof), other than the incurrence or repayment of

for Acquired Indebtedness and also including any Consolidated EBITDA (provided
that such Consolidated EBITDA shall be included only to the extent includable
pursuant to the definition of "Consolidated Net Income" or to the extent it is

Restricted Subsidiaries are, liable for the same Indebtedness, whether as

duplication. Furthermore, in calculating "Consolidated Fixed Charges" for

accrued at a fixed rate per annum equal to the rate of interest on such
Indebtedness in effect on the Transaction Date; (2) if interest on any
Indebtedness actually incurred on the Transaction Date may optionally be
determined at an interest rate based upon a factor of a prime or similar rate, a
eurocurrency interbank offered rate, or other rates, then the interest rate in
effect on the Transaction Date will be deemed to have been in effect during the
Four Quarter Period; and (3) notwithstanding clause (1) above, interest on
Indebtedness determined on a fluctuating basis, to the extent such interest is
covered by agreements relating to Interest Swap Obligations, shall be deemed to
accrue at the rate per annum resulting after giving effect to the operation of
such agreements.

period, the sum, without duplication, of (i) Consolidated Interest Expense, plus
(ii) to the extent not included in Consolidated Interest Expense, the product of

Person (other than dividends paid in Qualified Capital Stock) paid, accrued or
scheduled to be paid or accrued during such period times (y) a fraction, the
numerator of which is one and the denominator of which is one minus the then
current effective consolidated federal, state and local tax rate of such Person,
expressed as a decimal.
 
    "CONSOLIDATED INTEREST EXPENSE" means, with respect to any Person for any
period, the sum of, without duplication: (i) the aggregate of the interest
expense of such Person and its Restricted Subsidiaries for such period
determined on a consolidated basis in accordance with GAAP, including without
limitation, (a) any amortization of debt discount and amortization or write-off
of deferred financing costs, (b) the net costs under Interest Swap Obligations,
(c) all capitalized interest and (d) the interest portion of any deferred
payment obligation, less interest expense which is historically allocated to
discontinued operations (including, without limitation, operations disposed of
during such period whether or not such operations were classified as
discontinued) but only in the case of which such Person maintained separate
books and records with respect to such discontinued operations or such disposed
operations; and (ii) the interest component of Capitalized Lease Obligations
paid, accrued and/or scheduled to be paid or accrued by such
 
                                       89

referent Person, (d) the net income (but not loss) of any Restricted Subsidiary
of the referent Person to the extent that the declaration of dividends or
similar distributions by that Restricted Subsidiary of that income is restricted

dividends or distributions paid to the referent Person or to a Restricted
Subsidiary of the referent Person by such Person, (e) the net income of any
Person, other than a Restricted Subsidiary of the referent Person, except to the
extent of cash dividends or distributions paid to the referent Person or to a
Restricted Subsidiary of the referent Person by such Person, (f) any restoration
to income of any contingency reserve, except to the extent that provision for
such reserve was made out of Consolidated Net Income accrued at any time
following the Issue Date, (g) income or loss attributable to discontinued
operations (including, without limitation, operations disposed of during such
period whether or not such operations were classified as discontinued), and (h)

constituting an extraordinary item or loss or any such charge which requires an
accrual of or a reserve for cash charges for any future period).

Debt in respect of any Designated Senior Debt.

EXCHANGE OFFER; REGISTRATION RIGHTS
 
    The following summary of certain provisions of the Registration Rights
Agreement does not purport to be complete and is subject to, and is qualified in
its entirety by reference to, all the provisions of the Registration Rights
Agreement, a copy of which is filed as an exhibit to the Registration Statement
to which this Prospectus forms a part.
 
    Pursuant to the Registration Rights Agreement, each of the Company and the
Guarantors agreed that they, at their cost, for the benefit of the Holders, to
the extent not prohibited by any applicable law or applicable interpretation of
the staff of the Commission (i) prepare and, on or prior to July 1, 1998 (the
"Filing Date"), file with the Commission this Registration Statement with
respect to the Exchange Offer, (ii) use their best efforts to cause this
Registration Statement to be declared effective by the Commission under the
Securities Act on or prior to August 31, 1998, and (iii) commence the Exchange
Offer and use their best efforts to issue, on or prior to the date (the
"Consummation Date") that is 35 days immediately following the date that this
Registration Statement shall have been declared effective, the New Notes. The
offer and sale of the New Notes pursuant to the Exchange Offer is being
registered pursuant to this Registration Statement and will be duly registered
or qualified under all applicable state securities or Blue Sky laws and will
comply with all applicable tender offer rules and regulations under the Exchange
Act and state securities or Blue Sky laws. The Exchange Offer is not subject to
any condition, other than that the Exchange Offer does not violate any
applicable law or interpretation of the staff of the Commission.
 
    If, prior to consummation of the Exchange Offer, BT holds any Notes acquired
by it and having, or which are reasonably likely to be determined to have, the
status of an unsold allotment in the initial distribution, or any other holder
of Old Notes is not entitled to participate in the Exchange Offer, the Company
and the Guarantors, upon the request of such Initial Purchaser or any such
holder, shall, simultaneously with the delivery of the New Notes in the Exchange
Offer, issue and deliver to such Initial Purchaser and any such holder, in
exchange (the "Private Exchange") for such Old Notes held by such Initial
Purchaser and any such holder, a like principal amount of debt securities of the
Company, guaranteed by each of the Guarantors on a senior subordinated basis,
that are identical in all material respects to the New Notes other than transfer
restrictions (the "Private Exchange Notes").
 
                                      100
<PAGE>
    Interest on each New Note or Private Exchange Note will accrue (A) from the
later of (i) the last interest payment date on which interest was paid on the
Old Note surrendered in exchange therefor, or (ii) if the Old Note is
surrendered for exchange on a date in a period which includes the record date
for an interest payment date to occur on or after the date of such exchange and
as to which interest will be paid, the date of such interest payment date or (B)
if no interest has been paid on the Old Notes, from March 3, 1998.
 
    Under existing interpretations of the Commission contained in several
no-action letters to third parties, the New Notes (and the related Guarantees)
will be freely transferable by holders thereof (other than affiliates of any of
the Company or the Guarantors) after the Exchange Offer without further
registration under the Act; provided, however, that the Company and the
Guarantors may require each holder of Old Notes, as a condition to its
participation in the Exchange Offer, to represent to the Company and the
Guarantors and their counsel in writing (which may be contained in the
applicable letter of transmittal) that at the time of the consummation of the
Exchange Offer (i) any New Notes received by such holder will be acquired in the
ordinary course of its business, (ii) such holder will have no arrangement or
understanding with any person to participate in the distribution (within the
meaning of the Securities Act) of the New Notes and (iii) such holder is not an
affiliate (as defined in Rule 405 promulgated under the Securities Act) of the
Company, or if it is an affiliate of the Company, it will comply with the
registration and prospectus delivery requirements of the Securities Act, to the
extent applicable.
 
    If the holder is not a broker-dealer, it will be required to represent that
it is not engaged in, and does not intend to engage in, the distribution of the
New Notes. If the holder is a broker-dealer that will receive New Notes for its
own account in exchange for Old Notes that were acquired as a result of
market-making activities or other trading activities (a "Participating
Broker-Dealer"), it will be required to acknowledge that it will deliver a
prospectus in connection with any resale of such New Notes. Each of the Company
and the Guarantors has agreed to make available, during the period required by
the Securities Act, a prospectus meeting the requirements of the Securities Act
for use by Participating Broker-Dealers and other persons, if any, with similar
prospectus delivery requirements for use in connection with any resale of the
New Notes.
 
    If (i) the Company and the Guarantors are not permitted to file this
Registration Statement or to consummate the Exchange Offer because the Exchange
Offer is not permitted by any applicable law or applicable interpretation of the
staff of the Commission or (ii) any holder of an Old Note notifies the Company
that (A) due to a change in law or policy it is not entitled to participate in
the Exchange Offer, (B) due to a change in law or policy it may not resell New
Notes acquired by it in the Exchange Offer to the public without delivering a
prospectus and this Prospectus is not appropriate or available for such resales
by such holder or (C) it owns Old Notes (including if BT holds Old Notes as part
of an unsold allotment from the original offering of the Old Notes) acquired
directly from the Company or a Guarantor or an affiliate of the Company or a
Guarantor or (iii) any holder of Private Exchange Notes so requests after the
consummation of the Private Exchange or (iv) the Company and the Guarantors have
not consummated the Exchange Offer within 215 days after March 3, 1998 (each
such event referred to in clauses (i) through (iv), a "Shelf Filing Event"), the
Company and the Guarantors shall (a) promptly deliver to the holders and the
Trustee notice thereof and (b) at their own expense cause to be filed with the
Commission pursuant to Rule 415 a shelf registration statement (the "Shelf
Registration Statement") as promptly as practicable and in any event prior to 60
days after the Company and the Guarantors become aware that such filing
obligation arises relating to all Transfer Restricted Notes (as defined) (the
"Shelf Registration") the holders of which have provided certain information
requested by the Company (provided that if the Shelf Filing Event arises
pursuant to clause (iv) above, the Company and the Guarantors shall file the
Shelf Registration Statement on or prior to the 216th day after March 3, 1998),
and shall use their best efforts to have the Shelf Registration Statement
declared effective by the Commission on or prior to 60 days after the filing
thereof (the "Shelf Effective Date"). In such
 
                                      101
<PAGE>
circumstances, the Company and the Guarantors shall use their best efforts to
keep the Shelf Registration Statement continuously effective under the
Securities Act, until (A) two years (or such shorter period as may be
established by any amendment to the two year period set forth in Rule 144(k)
under the Securities Act) following the Shelf Effective Date or (B) if sooner,
the date immediately following the date that all Transfer Restricted Notes
covered by the Shelf Registration Statement have been sold pursuant thereto or
otherwise cease to be Transfer Restricted Notes (the "Effectiveness Period").
 
    For purposes of the foregoing, a "Transfer Restricted Note" means each Old
Note, each New Note as to which clause (ii) of the preceding paragraph is
applicable, and each Private Exchange Note, in each case upon original issuance
thereof and at all time subsequent thereto until the earliest to occur of (A)
the date on which any such note has been exchanged by a person other than a
Participating Broker-Dealer for a New Note (other than with respect to a New
Note as to which clause (ii) of the preceding paragraph applies) pursuant to the
Exchange Offer, (B) with respect to New Notes received by Participating Broker-
Dealers in the Exchange Offer, the earlier of (x) the date on which such New
Note has been sold by such Participating Broker-Dealer by means of this
Prospectus and (y) the date on which this Registration Statement has been
effective under the Securities Act for a period of six months after the date
that is 35 days immediately following the date that this Registration Statement
shall have been declared effective, (C) a Shelf Registration Statement covering
such Old Note, New Note or Private Exchange Note has been declared effective by
the Commission and such Old Note, New Note or Private Exchange Note, as the case
may be, has been disposed of in accordance with such effective Shelf
Registration Statement, (D) the date on which such Old Note, New Note or Private
Exchange Note, as the case may be, is eligible for distribution to the public
without volume or manner of sale restrictions pursuant to Rule 144(k) or (E) the
date on which such Old Note, New Note or Private Exchange Note, as the case may
be, ceases to be outstanding for purposes of the Indenture or any other
indenture under which such Old Note, New Note or Private Exchange Note was
issued.
 
    If the Company and the Guarantors fail to comply with the above provisions
or if this Registration Statement or the Shelf Registration Statement fails to
become effective, then, liquidated damages (the "Liquidated Damages") shall
become payable in respect of the Old Notes as follows:
 
        (i) if (A) neither this Registration Statement nor the Shelf
    Registration Statement is filed with the Commission on or prior to the
    Filing Date or (B) notwithstanding that the Company and the Guarantors have
    consummated or will consummate an Exchange Offer, the Company and the
    Guarantors are required to file a Shelf Registration Statement and such
    Shelf Registration Statement is not filed on or prior to the date required
    by the Registration Rights Agreement, then commencing on the day after
    either such required filing date, Liquidated Damages shall accrue on the
    principal amount of the Old Notes at a rate of 0.5% per annum for the first
    90 days immediately following each such filing date, such Liquidated Damages
    rate increasing by an additional 0.5% per annum at the beginning of each
    subsequent 90-day period; or
 
        (ii) if (A) this Registration Statement or a Shelf Registration
    Statement has been filed with the Commission but neither this Registration
    Statement nor a Shelf Registration Statement is declared effective by the
    Commission on or prior to 60 days after the applicable required filing date
    or (B) notwithstanding that the Company and the Guarantors have consummated
    or will consummate an Exchange Offer, the Company and the Guarantors are
    required to file a Shelf Registration Statement and such Shelf Registration
    Statement is not declared effective by the Commission on or prior to the
    60th day following the date such Shelf Registration Statement was required
    to be filed, then, commencing on the day after the 60th day following the
    applicable required filing date, Liquidated Damages shall accrue on the
    principal amount of the Old Notes at a rate of 0.5% per annum for the first
    90 days immediately following such date, such Liquidated Damages rate
    increasing by an additional 0.5% per annum at the beginning of each
    subsequent 90-day period; or
 
                                      102
<PAGE>
       (iii) if (A) the Company and the Guarantors have not exchanged New Notes
    for all Old Notes validly tendered in accordance with the terms of the
    Exchange Offer on or prior to the 36th day after the date on which this
    Registration Statement was declared effective or (B) if applicable, the
    Shelf Registration Statement has been declared effective and such Shelf
    Registration Statement ceases to be effective at any time prior to the
    expiration of the Effectiveness Period, then Liquidated Damages shall accrue
    on the principal amount of the Old Notes at a rate of 0.5% per annum for the
    first 90 days commencing on (x) the 36th day after such effective date, in
    the case of (A) above, or (y) the day such Shelf Registration Statement
    ceases to be effective in the case of (B) above, such Liquidated Damages
    rate increasing by an additional 0.5% per annum at the beginning of each
    subsequent 90-day period; provided, however, that the Liquidated Damages
    rate on the Old Notes may not exceed in the aggregate 2.00% per annum;
 
        provided, further, however, that (1) upon the filing of this
    Registration Statement or a Shelf Registration Statement (in the case of
    clause (i) above), (2) upon the effectiveness of this Registration Statement
    or a Shelf Registration Statement (in the case of clause (ii) above), or (3)
    upon the exchange of New Notes for all Old Notes validly tendered in
    accordance with the terms of the Exchange Offer (in the case of clause (iii)
    (A) above), or upon the effectiveness of the Shelf Registration Statement
    which had ceased to remain effective (in the case of clause (iii) (B)
    above), Liquidated Damages on the Old Notes as a result of such clause (or
    the relevant subclause thereof), as the case may be, shall cease to accrue.
    Liquidated Damages will not accrue because of the suspension of a Shelf
    Registration Statement during the pendency of certain blackout periods.
 
    Any Liquidated Damages will be payable in cash to record holders in the same
manner as interest will be payable on the Old Notes. Holders of Old Notes, who
tender such Notes in the Exchange Offer agree to waive any accrued but upaid
Liquidated Damages on such Old Notes. An amount equal to the amount of accrued
and unpaid Liquidated Damages on Old Notes tendered in the Exchange Offer shall
be payable to registered holders of New Notes on the record date for the first
interest payment following the consummation of the Exchange Offer.
 
    No holder of Transfer Restricted Notes shall be entitled to Liquidated
Damages payable in connection with any Shelf Registration Statement unless and
until such holder shall have provided certain information reasonably requested
by the Company for use in connection with such Shelf Registration Statement.
 
BOOK ENTRY; DELIVERY AND FORM
 
    Except as described in the next paragraph, the New Notes initially will be
represented by a single, permanent global Note, in definitive, fully registered
form without interest coupons (the "Global Note"). The Global Note will be
deposited on the date on which the Exchange Offer is consumated with, or on
behalf of, DTC and registered in the name of a nominee of DTC.
 
    New Notes held by Holders who elect to take physical delivery of their
certificates instead of holding their interests through a Global Note (and which
are thus ineligible to trade through DTC) (collectively referred to herein as
the "Non-Global Purchasers") will be issued in registered form (the
"Certificated Security"). Upon the transfer of any Certificated Security
initially issued to a Non-Global Purchaser, such Certificated Security will,
unless the transferee requests otherwise or the Global Note has previously been
exchanged in whole for Certificated Securities, be exchanged for an interest in
a Global Note.
 
    THE GLOBAL NOTE.  The Company expects that pursuant to procedures
established by DTC (i) upon the issuance of the Global Note, DTC or its
custodian will credit, on its internal system, the principal amount of New Notes
of the individual beneficial interests represented by such Global Note to the
respective accounts of persons who have accounts with such depositary and (ii)
ownership of beneficial interests in the Global Note will be shown on, and the
transfer of such ownership will be effected only through, records maintained by
DTC or its nominee (with respect to interests of participants) and the records
of participants (with respect to interests of persons other than participants).
Ownership of
 
                                      103
<PAGE>
beneficial interests in the Global Note will be limited to persons who have
accounts with DTC ("participants") or persons who hold interests through
participants. Holders may hold their interests in the Global Note directly
through DTC if they are participants in such system, or indirectly through
organizations which are participants in such system.
 
    So long as DTC, or its nominee, is the registered owner or holder of the
Global Note, DTC or such nominee, as the case may be, will be considered the
sole owner or holder of the New Notes represented by the Global Note for all
purposes under the Indenture. No beneficial owner of an interest in the Global
Note will be able to transfer that interest except in accordance with DTC's
procedures, in addition to those provided for under the Indenture with respect
to the New Notes.
 
    Payments of the principal of, premium (if any), and interest on, the Global
Note will be made to DTC or its nominee, as the case may be, as the registered
owner thereof. None of the Company, the Trustee or any paying agent will have
any responsibility or liability for any aspect of the records relating to or
payments made on account of beneficial ownership interests in the Global Note or
for maintaining, supervising or reviewing any records relating to such
beneficial ownership interest.
 
    The Company expects that DTC or its nominee, upon receipt of any payment of
principal, premium, if any, or interest on the Global Note, will credit
participants' accounts with payments in amounts proportionate to their
respective beneficial interests in the principal amount of the Global Note as
shown on the records of DTC or its nominee. The Company also expects that
payments by participants to owners of beneficial interests in the Global Note
held through such participants will be governed by standing instructions and
customary practice, as is now the case with securities held for the accounts of
customers registered in the names of nominees for such customers. Such payments
will be the responsibility of such participants.
 
    Transfers between participants in DTC will be effected in the ordinary way
through DTC's same-day funds system in accordance with DTC rules and will be
settled in same day funds. If a holder requires physical delivery of a
Certificated Security for any reason, including to sell New Notes to persons in
states which require physical delivery of the New Notes, or to pledge such
securities, such holder must transfer its interest in the Global Note, in
accordance with the normal procedures of DTC and with the procedures set forth
in the Indenture.
 
    DTC has advised the Company that it will take any action permitted to be
taken by a holder of New Notes only at the direction of one or more participants
to whose account the DTC interests in the Global Note are credited and only in
respect of such portion of the aggregate principal amount of New Notes as to
which such participant or participants has or have given such direction.
However, if there is an Event of Default under the Indenture, DTC will exchange
the Global Note for Certificated Securities, which it will distribute to its
participants.
 
    DTC has advised the Company as follows: DTC is a limited purpose trust
company organized under the laws of the State of New York, a member of the
Federal Reserve System, a "clearing corporation" within the meaning of the
Uniform Commercial Code and a "Clearing Agency" registered pursuant to the
provisions of Section 17A of the Exchange Act. DTC was created to hold
securities for its participants and to facilitate the clearance and settlement
of securities transactions between participants through electronic book-entry
changes in accounts of its participants, thereby eliminating the need for
physical movement of certificates. Participants include securities brokers and
dealers, banks, trust companies and clearing corporations and certain other
organizations. Indirect access to the DTC system is available to others such as
banks, brokers, dealers and trust companies that clear through or maintain a
custodial relationship with a participant, either directly or indirectly
("indirect participants").
 
    Although DTC has agreed to the foregoing procedures in order to facilitate
transfers of interests in the Global Note among participants of DTC, it is under
no obligation to perform such procedures, and such procedures may be
discontinued at any time. Neither the Company nor the Trustee will have any
 
                                      104
<PAGE>
responsibility for the performance by DTC or its participants or indirect
participants of their respective obligations under the rules and procedures
governing their operations.
 
    CERTIFICATED SECURITIES.  If DTC is at any time unwilling or unable to
continue as a depositary for the Global Note and a successor depositary is not
appointed by the Company within 90 days, Certificated Securities will be issued
in exchange for the Global Note.
 
                        CERTAIN FEDERAL TAX CONSEQUENCES
 
    The following is a summary of certain Federal income tax consequences
associated with the exchange of Old Notes for New Notes and the disposition of
the New Notes. This summary is based upon existing Federal income tax law, which
is subject to change, possibly retroactively. This summary does not discuss all
aspects of Federal income taxation which may be important to particular Holders
in light of their individual investment circumstances, such as Notes held by
investors subject to special tax rules (E.G., financial institutions, insurance
companies, broker-dealers, tax-exempt organizations, or foreign investors) or to
persons that hold the Old Notes or will hold the New Notes as a part of a
straddle, hedge, or synthetic security transaction for Federal income tax
purposes, all of whom may be subject to tax rules that differ significantly from
those summarized below. In addition, this summary does not discuss any foreign,
state, or local tax considerations. This summary addresses tax consequences only
to current Holders of Notes and assumes that such Holders hold their Old Notes
and will hold their New Notes as "capital assets" (E.G., generally, property
held for investment). Holders are urged to consult their tax advisors regarding
the Federal, state, local and foreign income and other tax considerations
associated with the exchange of Old Notes for New Notes and the disposition of
the New Notes.
 
EXCHANGE OF NOTES
 
    There will be no Federal income tax consequences to a Holder exchanging an
Old Note for a New Note pursuant to the Exchange Offer and such holder will have
the same adjusted basis and holding period in the New Note as it had in the Old
Note immediately before the exchange.
 
DISPOSTION OF NEW NOTES
 
    In general, subject to the market discount rules discussed below, a Holder
of a New Note will recognize capital gain or loss upon the sale, redemption, or
other disposition of the New Note in an amount equal to the difference between
the amount realized (except to the extent attributable to accrued but unpaid
interest) in such disposition and the Holder's adjusted tax basis in the New
Note. Under recently adopted amendments to the Internal Revenue Code, net
capital gain (I.E., generally, capital gain in excess of capital loss)
recognized by an individual Holder upon a disposition of a New Note that has
been held for more than 12 months will generally be subject to a maximum tax
rate of 20% or, in the case of a New Note that has been held for 12 months or
less, will be subject to tax at ordinary income tax rates. In addition, capital
gain recognized by a corporate Holder will be subject to tax at the ordinary
income tax rates applicable to corporations.
 
MARKET DISCOUNT
 
    Holders, other than original purchasers of the Old Notes in the original
offering, should be aware that the sale of the New Notes may be affected by the
market discount provisions of the Internal Revenue Code. These rules generally
provide that if a Holder of a Note purchased such note, subsequent to the
original offering, at a market discount in excess of a statutorily defined DE
MINIMIS amount, and thereafter recognizes gain upon a disposition (including a
partial redemption) of the New Note received in exchange for such Old Note, the
lesser of such gain or the portion of the market discount that accrued while the
Old Note and New Note were held by such holder will be treated as ordinary
interest income at the time of disposition. The rules also provide that a Holder
who acquires a Note at a market discount may be
 
                                      105
<PAGE>
required to defer a portion of any interest expense that may otherwise be
deductible on any indebtedness incurred or maintained to purchase or carry such
note until the Holder disposes of such note in a taxable transaction. If a
Holder of such a note elects to include market discount in income currently,
both of the foregoing rules would not apply.
 
                              PLAN OF DISTRIBUTION
 
    Each broker-dealer that receives New Notes for its own account pursuant to
the Exchange Offer must acknowledge that it will deliver this Prospectus in
connection with any resale of such New Notes. This Prospectus, as it may be
amended or supplemented from time to time, may be used by a broker-dealer in
connection with resales of New Notes received in exchange for Old Notes where
such Old Notes were acquired as a result of market-making activities or other
trading activities. Until [            ], 1998, all dealers effecting
transactions in the New Notes may be required to deliver this Prospectus. The
Company has agreed that, for a period of 90 days after the Expiration Date, it
will make this Prospectus, as amended or supplemented, available to any
broker-dealer for use in connection with any such resale.
 
    The Company will not receive any proceeds from any sale of New Notes by
broker-dealers. New Notes received by broker-dealers for their own account
pursuant to the Exchange Offer may be sold from time to time in one or more
transactions in the over-the-counter market, in negotiated transactions, through
the writing of options on the New Notes or a combination of such methods of
resale, at market prices prevailing at the time of resale, at prices related to
such prevailing market prices or negotiated prices. Any such resale may be made
directly to purchasers or to or through brokers or dealers who may receive
compensation in the form of commissions or concessions from any such
broker-dealer or the purchaser of any such New Notes. Any broker-dealer that
resells New Notes that were received by it for its own account pursuant to the
Exchange Offer and any broker or dealer that participates in a distribution of
such New Notes may be deemed to be an "underwriter" within the meaning of the
Securities Act and any profit on any such resale of New Notes and any commission
or concessions received by any such person may be deemed to be underwriting
compensation under the Securities Act. The Letter of Transmittal states that, by
acknowledging that it will deliver and by delivering this Prospectus, a
broker-dealer will not be deemed to admit that it is an "underwriter" within the
meaning of the Securities Act.
 
    For a period of 90 days after the Expiration Date, the Company will promptly
send additional copies of this Prospectus and any amendment or supplement to
this Prospectus to any broker-dealer that requests such documents in the Letter
of Transmittal. The Company has agreed to pay all expenses in connection with
the Exchange Offer and to reimburse BT for the reasonable fees and expenses of
counsel for the Holders of the Notes. Each Holder will pay all expenses of its
counsel other than as described in the preceding sentence, transfer taxes, if
any, and any commissions or concessions of any brokers or dealers. The Company
has agreed in the Registration Rights Agreement to indemnify the Holders of the
Notes (including any broker-dealer) against certain liabilities, including
liabilities under the Securities Act.
 
    In addition, to comply with the securities laws of certain jurisdictions,
the New Notes may not be offered or sold unless they have been registered or
qualified for offer and sale in such jurisdiction or an exemption from
registration or qualification is available and is complied with. The Company has
agreed, pursuant to the Registration Rights Agreement, subject to certain
limitations specified therein, to register or qualify the New Notes for offer or
sale under all applicable state securities or Blue Sky laws by the time the
Registration Statement (of which this Prospectus forms a part) is declared
effective by the Commission.
 
                                 LEGAL MATTERS
 
    Certain legal matters with respect to the New Notes offered hereby will be
passed upon for the Company by its special counsel, Skadden, Arps, Slate,
Meagher & Flom LLP, Los Angeles, California.

                       CHANGE IN INDEPENDENT ACCOUNTANTS
 
PREVIOUS INDEPENDENT ACCOUNTANTS
 
    On October 25, 1996, the Company dismissed Coopers & Lybrand L.L.P. as its
independent accountants. The report of Coopers & Lybrand L.L.P. on the Company's
financial statements for the fiscal year ended December 31, 1995 contained no
adverse opinion or disclaimer of opinion and was not qualified or modified as to
uncertainty, audit scope or accounting principle. The Company's Board of
Directors participated in and approved the decision to change independent
accountants. In connection with its audit for the fiscal year ended December 31,
1995, and through October 25, 1996, there were no disagreements with Coopers &
Lybrand L.L.P. on any matter of accounting principles or practices, financial
statement disclosure, or auditing scope or procedure, which disagreements if not
resolved to the satisfaction of Coopers & Lybrand L.L.P. would have caused them
to make reference thereto in their report on the financial statements for such
year.
 
    During the fiscal year ended December 31, 1995, and through October 25,
1996, there were no reportable events (as defined in Regulations S-K Item
304(a)(1)(v)).
 
NEW INDEPENDENT ACCOUNTANTS
 
    The Company engaged Deloitte & Touche LLP as its new independent accountants
as of October 25, 1996. During the fiscal year ended December 31, 1995 and
through October 25, 1996, the Company did not consult with Deloitte & Touche LLP
regarding either (i) the application of accounting principles to a specific
transaction either completed or proposed or the type of audit opinion that might
be rendered on the Company's financial statements, and neither a written report
was provided to the Company nor oral advice was provided that Deloitte & Touche
LLP concluded was an important factor considered by the Company in reaching a
decision as to the accounting, auditing or financial reporting issue; or (ii)
any matter that was either the subject of a disagreement, as that term is
defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions to
Item 304 of Regulation S-K, or a reportable event, as that term is defined in
Item 304(a)(1)(v) of Regulation S-K.

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. These condensed consolidated financial statements should be read in
conjunction with the consolidated financial statements and the notes thereto for
the year ended December 31, 1997. In the opinion of management, the condensed
consolidated financial statements included herein reflect all adjustments
necessary to present fairly the consolidated financial position of the Company
as of June 27, 1998, the results of its operations for the six month period
ended June 27, 1998, and its cash flows for the six month period ended June 27,
1998. The results of operations for the interim periods are not necessarily
indicative of the results of operations for the full year.
 
    As of January 1, 1998, the Company acquired from CCL Industries, all of the
outstanding shares of Kolmar Laboratories, Inc. and the net assets of Kolmar
Canada Inc., (collectively referred to as the Kolmar Group) for $78.0 million,
subject to certain post-closing adjustments. The acquisition has been treated as
a purchase for accounting purposes. Accordingly, the assets acquired and
liabilities assumed have been recorded at their estimated fair values at the
date of acquisition.
 
    The allocation of the purchase price is as follows:

    Goodwill associated with the Kolmar Acquisition is being amortized on a
straight-line basis over a 40 year period.
 
    Assuming the Kolmar Group acquisition had occurred on January 1, 1997, pro
forma net revenue and net loss for OSG for the year ended December 31, 1997
would have been approximately $213,469,000 and $857,000, respectively.

        NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
            FOR THE SIX MONTHS ENDED JUNE 29, 1997 AND JUNE 27, 1998
 
                                  (UNAUDITED)
 
1. BASIS OF PRESENTATION (CONTINUED)
    In conjunction with the Kolmar Group acquisition, the Company refinanced all
of its existing indebtedness. Deferred financing costs of $1,111,000 associated
with this indebtedness were written off in the first quarter of 1998. The
purchase price and the repayment of existing debt, plus $7.4 million of related
fees and expenses were financed through $30.0 million of borrowings under a
senior secured credit facility, $70.0 million of borrowings under a senior
subordinated credit agreement, and the issuance of 2,093,000 shares of the
Company's common stock to existing stockholders of the Company. Loans under the
senior secured credit facility and the senior subordinated credit agreement bear
interest at rates of approximately 9.25% and 11.6%, respectively.
 
    On March 3, 1998, the Company repaid indebtedness incurred in conjunction
with the Kolmar Group acquisition, using the proceeds from the issuance of $105
million senior subordinated notes which are due in 2006. Interest on the notes
is payable semiannually in arrears on March 1 and September 1 of each year,
commencing September 1, 1998, at the rate of 10.875% per annum. The notes are
redeemable in whole or in part at the option of the Company, on or after March
1, 2003 at the redemption price of 110.875% of the aggregate principal amount to
be redeemed plus accrued and unpaid interest to the redemption date. In
addition, at any time on or prior to March 1, 2001, the Company, at its option,
may redeem up to 35% of the aggregate principal amount of the notes originally
issued with the net cash proceeds of one or more equity offerings at the
redemption price plus accrued and unpaid interest to the redemption date;
provided that at least 65% of the aggregate principal amount of the notes
originally issued remains outstanding immediately after such redemption. The
notes are unsecured senior subordinated obligations of the Company and are
subordinated in right of payment to all existing and future senior debt of the
Company.
 
2. EARNINGS PER SHARE
 
    The Company has adopted SFAS No. 128, Earnings per Share, which replaces the
presentation of "primary" earnings per share with "basic" earnings per share and
the presentation of "fully diluted" earnings per share with "diluted" earnings
per share. All previously reported earnings per share amounts have been restated
based on the provisions of the new standard. Basic earnings per share are based
upon the weighted average number of common shares outstanding. Diluted earnings
per share amounts are based upon the weighted average number of common and
common equivalent shares for each period presented. Common equivalent shares
include stock options assuming conversion under the treasury stock method.
 
3. NEW ACCOUNTING PRONOUNCEMENTS
 
    In the first quarter ended March 28, 1998, the Company adopted SFAS No. 130,
REPORTING COMPREHENSIVE INCOME. This statement establishes standards for the
reporting and display of comprehensive income and its components. June 29, 1997
statements have been restated based on the provisions of the new standard. For
the fiscal year ending December 31, 1998, the Company will adopt SFAS No. 131,
DISCLOSURES ABOUT SEGMENTS OF AN ENTERPRISE AND RELATED INFORMATION and SFAS No.
132, DISCLOSURES ABOUT PENSIONS AND OTHER POSTRETIREMENT BENEFITS. SFAS No. 133,
ACCOUNTING FOR DERIVITIVE INSTRUMENTS AND HEDGING ACTIVITIES, will be adopted in
the quarter ended September 30, 1999. However, management believes that the
adoption of SFAS No. 133 will not impact the financial statements of the Company
as the Company is not currently involved in, nor does it anticipate being
involved in, derivative instruments or hedging activities.

5. CONTINGENCIES
 
    ENVIRONMENTAL CONTINGENCIES
 
    The Company is subject to loss contingencies resulting from environmental
laws and regulations, which include obligations to remove or remediate the
effects on the environment of the disposal or release of certain wastes and
substances at various sites. The Company has established accruals in current
dollars for those hazardous waste sites where it is probable that a loss has
been incurred and the amount of the loss can reasonably be estimated. The
reliability and precision of the loss estimates are affected by numerous
factors, such as different stages of site evaluation, the allocation of
responsibility among potentially responsible parties and the assertion of
additional claims. The Company adjusts its accruals as new remediation
requirements are defined, as information becomes available permitting reasonable
estimates to be made, and to reflect new and changing facts. The Company also
has established receivables for insurance recoveries (for liabilities on
existing sites) that are probable of collection.
 
    At December 27, 1997 and June 27, 1998, the Company had established
environmental remediation accruals in the amount of $14,500,000.
 
    The Company potentially has minor responsibility for the remediation of four
environmental sites for which accruals have been established. These sites are
well advanced in the investigation and cleanup stage. The Company's
environmental accruals at December 31, 1997 and June 27, 1998, included $750,000
for these sites. The site with the largest total potential cost to the Company
is a nonoperating site. Of the above accruals, this site accounted for
$8,500,000 at December 31, 1997 and June 27, 1998. At December 31, 1997 and June
27, 1998, the Company has a long-term receivable totaling $8,250,000 for
insurance recoveries on this site which are probable of collection.
 
    The Company maintains environmental exposure for one other site. To date the
Company has not been named a potentially responsible party for this site but
maintained an accrual of $5,250,000 as of December 31, 1997 and June 27, 1998,
based on the advice of outside counsel, for an estimate of probable groundwater
and soil remediation costs. The Company believes this estimate would cover the
full remediation of the site.
 
    While it is impossible at this time to determine with certainty the ultimate
outcome of the environmental matters referred to in this note, management
believes that adequate provisions have been made for probable losses with
respect thereto and that such ultimate outcome, after provisions therefore, will
not have a material adverse effect on the combined financial position of the
Company, but could have a

            FOR THE SIX MONTHS ENDED JUNE 29, 1997 AND JUNE 27, 1998
 
                                  (UNAUDITED)
 
5. CONTINGENCIES (CONTINUED)
material effect on combined results of operations in a given year. 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 to income in the future.
 
    LITIGATION
 
    A claim has been asserted by the U.S. Environmental Protection Agency
against the Company potentially responsible for the remediation of a superfund
site near Port Jervis, New York. The proceedings remain administrative only, and
are not pending as litigation in any U.S. District Court. The Company has
reserves for any potential liability that may arise out of this claim and has
recorded insurance receivables relating to this claim which it believes are
probable of recovery.
 
    There are certain other legal proceedings and claims pending against the
Company arising out of the normal course of business in 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 in excess of reserved amounts will not individually or in the
aggregate have a material adverse effect on the Company's financial position or
results of operations.
 
   
6. SUPPLEMENTAL GUARANTOR INFORMATION
    
 
   
    The payment obligations of the Company under the Notes are to be 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 unaudited condensed combined
balance sheets as of June 27, 1998 and June 29, 1997 and the unaudited condensed
combined statements of income and cash flows for the six months ended June 27,
1998 and June 29, 1997 of the Guarantors, representing Kolmar, ASC and Piedmont
and the nonguarantors which consist of Kolmar Canada, a division of CCL, 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
nonguarantor operations of the Company, based on amounts derived from the
financial statements of the Company and of the Kolmar Group, as of and for the
periods presented.
    
 
   
    The condensed combined Guarantor and nonguarantor financial information is
presented for informational purposes only and does not purport to represent the
combined financial position or results of operations of these entities as of the
date presented, or to project their financial condition or results of operations
for any future period or date. The condensed combined Guarantor and nonguarantor
financial information should be read in conjunction with the historical
consolidated financial statements and related notes and the "Management's
Discussion and Analysis of Financial Condition and Results of Operations,"
contained elsewhere in the Registration Statement. Each Guarantor is a
wholly-owned subsidiary of the Company and has fully and unconditionally
guaranteed the Notes on a joint and several basis. The Company has not presented
separate financial statements and other disclosures concerning the Guarantors
because management has determined that such information is not material to
investors.

To the Board of Directors
 
Outsourcing Services Group, Inc.
 
City of Industry, California
 
    We have audited the accompanying consolidated balance sheets of Outsourcing
Services Group, Inc. (the Company or OSG) as of December 31, 1996 and 1997, and
the related consolidated statements of operations, stockholders' deficit and
cash flows for each of the three years in the period ended December 31, 1997.
These financial statements are the responsibility of the Company's management.
Our responsibility is to express an opinion on the financial statements based on
our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the consolidated financial statements present fairly, in all
material respects, the financial position of Outsourcing Services Group, Inc. as
of December 31, 1996 and 1997, and the results of its operations and its cash
flows for each of the years in the period ended December 31, 1997 in conformity
with generally accepted accounting principles.
 
    During the year ended December 31, 1996, the Company changed its method of
evaluating the recoverability of intangible assets.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
              FOR THE YEARS ENDED DECEMBER 31, 1995, 1996 AND 1997
 
1.  ORGANIZATION AND BACKGROUND
 
    BUSINESS--Outsourcing Services Group, Inc. (the Company or OSG) 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,
including 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.
 
    FORMATION--The Company was established as a result of the merger of Aerosol
Services Holding Corporation (ASHC) and Aerosol Companies Holding Corporation
(ACHC) in a transaction accounted for similar to a pooling of interest. Such
accounting treatment is in accordance with Interpretation No. 39 of APB Opinion
16 and is appropriate for entities under common control and results in the
combined assets and liabilities for both entities being recorded at their
historical cost.
 
    ASHC was formed by an investor group to acquire Aerosol Services Company,
Inc. (ASC), effective February 14, 1994, for approximately $35,000,000. The
purchase price was financed primarily through the issuance of debt and equity
securities. ACHC was formed by essentially the same investor group plus
management of Piedmont Laboratories, Inc. (Piedmont) to acquire Piedmont on
October 1, 1996 for approximately $14,060,000. The purchase price was financed
primarily through the issuance of debt and equity securities. The acquisition
has been accounted for as a purchase for accounting purposes and, accordingly,
the assets acquired and liabilities assumed have been recorded at their
estimated fair values at the date of acquisition. The excess of the purchase
price over the fair value of the net assets acquired was $5,754,000 and has been
recorded as goodwill. Other intangible assets arising from this transaction
amounted to $999,000. Assuming the Piedmont acquisition had occurred on January
1, 1996, pro forma net revenues and net loss for OSG for the year ended December
31, 1996 would have been approximately $107,708,000 and $(5,296,000),
respectively.
 
    MERGER--Under the terms of the merger, effective June 30, 1997, ACHC was
merged into ASHC at which time, ASHC was renamed Outsourcing Services Group,
Inc. As a result of this merger, the Company became the sole common stockholder
of ASC and Piedmont. The merger agreement also amended the capital structure
such that the existing stockholders of ACHC received approximately 1.22 new
shares of the Company's common stock for each old share of ACHC common stock
that they owned prior to the merger and the existing stockholders of ASHC
received approximately .76 new shares of the Company's common stock for each old
share of ASHC common stock that they owned prior to the merger. In addition, the
outstanding preferred stock was canceled and new shares of preferred stock were
issued in the form of a Series A preferred stock and Series B preferred stock
(Note 9).
 
2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    PRINCIPLES OF CONSOLIDATION--The consolidated financial statements include
the accounts of the Company and its wholly-owned subsidiaries, Aerosol Services
Company, Inc. and Piedmont Laboratories, Inc. subsequent to its acquisition on
October 1, 1996. All significant intercompany transactions have been eliminated.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
              FOR THE YEARS ENDED DECEMBER 31, 1995, 1996 AND 1997
 
2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    BASIS OF PRESENTATION--OSG's financial statements give retroactive effect to
the formation of OSG and to the acquisition of Piedmont as if it was acquired by
OSG on October 1, 1996.
 
    SHORT-TERM INVESTMENT--Short-term investment consists of a certificate of
deposit with an original maturity of greater than three months and a remaining
maturity of less than one year. Short-term investment is stated at cost which
approximates market value.
 
    INVENTORIES--Inventories are valued at the lower of cost or market using the
first-in, first-out (FIFO) method.
 
    PROPERTY AND EQUIPMENT--Property and equipment are stated at cost, less
accumulated depreciation and amortization. Depreciation and amortization are
provided principally using the straight-line method over the estimated useful
lives of the related assets ranging from 3 to 20 years. Expenditures for major
renewals and betterments are capitalized, while minor replacements, maintenance
and repairs which do not extend the asset lives are charged to operations as
incurred.
 
    OTHER INTANGIBLE ASSETS--Other intangible assets which include organization
and other costs are being amortized on a straight-line basis over a 60-month
period.
 
    DEFERRED FINANCING COSTS--Deferred financing costs are capitalized costs
associated with obtaining long-term debt financing including legal expenses,
bank fees and seller's costs. These costs are being amortized over the repayment
term of the related debt using the effective interest method.
 
   
    GOODWILL--Goodwill represents the excess of the purchase price over the fair
value of the net assets of ASC and Piedmont and is amortized on a straight-line
basis over five years. The Company subjects the carrying value of the goodwill
to an annual review for impairment. Effective January 1, 1996, the Company
changed its accounting policy for evaluating the recoverability of intangible
assets. Previously, the Company determined the recoverability of intangible
assets by considering estimated future operating income of the Company on an
undiscounted cash flow basis. Under its new policy, the Company evaluates the
recoverability of intangible assets based on the estimated fair market value of
the Company. Management changed its accounting policy because it concluded that
a fair value approach was a better measure of the future benefit of goodwill.
The cumulative effect of the change in accounting policy has resulted in a
write-down of goodwill associated with the acquisition of ASC of $7,000,000.
Goodwill is presented net of accumulated amortization of $2,421,000 in 1996 and
$4,326,000 in 1997.
    
 
    The fair value method will be applied to each of OSG's operating entities.
Management's estimate of fair value will primarily be based on multiples of
forecasted EBITDA. The multiples will be determined based upon publicly
available information regarding comparable publicly-traded companies in the
industry, but will also consider (i) the financial projections of each entity,
(ii) the future prospects of each entity, including its growth opportunities and
likely operational improvements, and (iii) comparable transaction prices, if
available. While management believes the estimation methods are reasonable and
reflective of common valuation practices, there can be no assurance that a sale
to a buyer for the estimated value ascribed to each entity could be completed.
Changes to the method of valuing operating entities will be made only when there
is a significant and fundamental change in facts and circumstances, such as
significant changes in market position or the entrance or exit of a significant
competitor from a regional market.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
              FOR THE YEARS ENDED DECEMBER 31, 1995, 1996 AND 1997
 
2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    OSG management will perform a review of each operating entity on an annual
basis (unless circumstances dictate that a review is needed in an interim
period) to determine if events or changes in circumstances were deemed to have
occurred which would have an impact on the fair value of the operating entity.
Should the estimated fair value of an operating entity be less than the carrying
value of its identifiable assets, the Company would record a charge to
operations to recognize an impairment of its intangible assets for such
difference.
 
    PREDECESSOR CARRYOVER BASIS ADJUSTMENT--The assets and liabilities
attributed to the former stockholders of ASC, who retained a 33.63% interest in
ASHC, subsequent to the acquisition, were recorded at the predecessor basis in
accordance with generally accepted accounting principles. The assets and
liabilities attributed to the former stockholders were $14,652,155 and
$11,483,856, respectively. The new basis of reporting for the Company's net
assets using fair market values at the date of the acquisition was reduced by
$9,715,000 to reflect the carryover basis of the former stockholder of ASC. This
predecessor carryover basis adjustment is reflected as a reduction of
stockholders' equity. A corresponding adjustment was determined to be immaterial
for the acquisition of Piedmont.
 
    LONG-LIVED ASSETS--The Company accounts for the impairment and disposition
of long-lived assets in accordance with Statement of Financial Accounting
Standards (SFAS) No. 121, ACCOUNTING FOR THE IMPAIRMENT OF LONG-LIVED ASSETS AND
FOR LONG-LIVED ASSETS TO BE DISPOSED OF. In accordance with SFAS No. 121,
long-lived assets to be held are reviewed for events or changes in circumstances
which indicate that their carrying value may not be recoverable. The Company
periodically reviews the carrying value of long-lived assets to determine
whether or not an impairment to such value has occurred.
 
    OVERDRAFT--As a result of cash management policies, the Company maintains
overdraft positions in certain cash accounts. Overdrafts at December 31, 1996
and 1997, which are included in accounts payable, were $1,162,000 and
$1,627,000, respectively.
 
    REVENUE RECOGNITION--Revenue is generally recognized as products are shipped
to customers. When customers, under the terms of specific orders, request that
the Company manufacture and invoice goods on a bill and hold basis, the Company
recognizes revenue based on the completion of the manufacturing process. The
Company estimates and records provisions for sales returns and allowances based
on its experience. Total sales returns and allowances were $1,688,000,
$1,094,000 and $1,537,000 in 1995, 1996 and 1997, respectively.
 
    INCOME TAXES--The Company accounts for income taxes under the provisions of
SFAS No. 109, ACCOUNTING FOR INCOME TAXES. Under this method, deferred income
taxes are recognized for the tax consequences in future years of differences
between the tax bases of assets and liabilities and their financial reporting
amounts at each year-end based on enacted tax laws and statutory rates
applicable to the periods in which the differences are expected to affect
taxable income. Valuation allowances are established, when necessary, to reduce
deferred tax assets to the amount expected to be realized.
 
    CONCENTRATION OF CREDIT RISK--Financial instruments which potentially expose
the Company to concentration of credit risk consist primarily of cash and trade
accounts receivable. The Company maintains cash balances with financial
institutions that are in excess of federally insured limits. The Company's
products are primarily sold to product marketers which, in turn, sell or
distribute to retail stores and salons. These customers can be affected by
changes in economic, competitive or other factors. The Company makes

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
              FOR THE YEARS ENDED DECEMBER 31, 1995, 1996 AND 1997
 
2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
substantial sales to relatively few, large customers. Credit limits, ongoing
credit evaluations, and account monitoring procedures are utilized to minimize
the risk of loss. Collateral is generally not required.
 
    USE OF ESTIMATES AND ASSUMPTIONS--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, 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.
 
    FAIR VALUE OF FINANCIAL INSTRUMENTS--The Company's consolidated balance
sheets include the following financial instruments: short-term investment, trade
accounts receivable, trade accounts payable and long-term debt. The Company
considers the carrying amounts in the financial statements to approximate fair
value of these financial instruments due to the relatively short period of time
between the origination of the instruments and their expected realization or the
interest rates which approximate current market rates.
 
    MAJOR CUSTOMERS--During fiscal years 1995, 1996 and 1997, two customers
accounted for approximately 49%, 38% and 35%, respectively, of revenues. A
decision by a significant customer to decrease the amount purchased from the
Company or to cease carrying the Company's products could have a material effect
on the Company's financial condition and results of operations.
 
    RESEARCH AND DEVELOPMENT COSTS--Research and development costs are expensed
when incurred. Included in general and administrative expenses for the fiscal
years 1995, 1996 and 1997 is approximately $159,000, $191,000 and $298,000,
respectively, of research and development costs for the development and
improvement of the Company's products.
 
    RECLASSIFICATIONS--Certain reclassifications have been made to the 1996
financial statements to conform with the 1997 presentation.
 
    NET INCOME (LOSS) PER SHARE--The Company has adopted SFAS No. 128, EARNINGS
PER SHARE, which replaces the presentation of "primary" earnings per share with
"basic" earnings per share and the presentation of "fully diluted" earnings per
share with "diluted" earnings per share. All previously reported earnings per
share amounts have been restated based on the provisions of the new standard.
Basic earnings per share are based upon the weighted average number of common
shares outstanding. Diluted earnings per share amounts are based upon the
weighted average number of common and common equivalent shares for each period
presented. Common equivalent shares include stock options assuming conversion
under the treasury stock method. Diluted earnings per share have not been
presented in the accompanying financial statements because the effect was either
antidilutive or the same as basic earnings per share.
 
    RECENTLY ISSUED ACCOUNTING STANDARDS--For fiscal year beginning after
December 15, 1997, the Company will adopt SFAS No. 130, REPORTING COMPREHENSIVE
INCOME, and SFAS No. 131, DISCLOSURES ABOUT SEGMENTS OF AN ENTERPRISE AND
RELATED INFORMATION. The Company is reviewing the impact of such accounting
pronouncements on its financial statements.

time of the exchange. The warrants expire on June 30, 2007. The Company may not
call the warrants prior to June 30, 2003. Thereafter, the Company may from time
to time call all of the outstanding warrants at a call price equal to the fair

payments were made.

    The holders of Series A preferred stock are entitled to noncumulative
dividends at a rate of $2.50 per share, per quarter, accruing from the date of
issuance, payable quarterly. If current dividends are not declared and paid with
respect to any dividend payment date, then the holders of the Series A preferred
stock are entitled to receive an increased cumulative dividend in cash equal to
$3.25 per share for the first dividend period for which a dividend was not
declared. Subsequently, the amount of the unpaid dividend shall increase by 2.5%
or 3.25% of the liquidation preference per quarter, depending on whether
subsequent dividend payments are made. The holders of Series B preferred stock
are entitled to cumulative dividends at a rate of $2.00 per share, per quarter,
accruing from June 30, 1997, payable quarterly. The Series B dividends shall
accrue and be cumulative whether or not they have been declared.
 
    At any time after June 30, 2000, the Company may, at the option of the Board
of Directors, redeem all or part of the outstanding shares of the Series A and
Series B preferred stock at a redemption price of $100.00 and $145.97 per share,
respectively, plus an amount equal to all accrued and unpaid dividends. The
Company is required to redeem all outstanding shares on the earlier of June 30,
2006, an initial public offering of the Company's common stock or a liquidation,
dissolution or winding up of the Company. Holders of Series A and Series B
preferred stock have a liquidation preference of $100.00 and $145.97 per share,
respectively, plus an amount equal to all accrued and unpaid dividends. Except
as required by law, the holders of Series A and Series B preferred stock are not
entitled to vote on any matters.
 
    As of December 31, 1996 and 1997, cumulative and undeclared dividends in
arrears amounted to $1,118,000 and $53,000, respectively. The accrued dividends
are being accreted annually as an increase to the value of the preferred stock
and a reduction in retained earnings.

    SELF-INSURANCE PROGRAMS--The Company participates in a self-insured group
health program for employees of Piedmont, whereby the first $50,000 of claims
for each employee will be paid by the Company. The Company also participates in
a self-insured workers' compensation program for employees of Piedmont, whereby
the Company will pay the first $100,000 per claim. The Company has accrued
$100,000 and $279,000 as of December 31, 1996 and 1997, respectively, for unpaid
claims.
 
    PRODUCT LIABILITY INSURANCE--The Company maintains product liability
insurance which provides coverage in the amount of $51 million per occurrence
(above a $25,000 per occurrence self-insured retention) and $52 million in the
aggregate (above a $250,000 annual aggregate self-insured retention). A product
liability claim that results in a judgment or settlement in excess of the
Company's insurance coverage could have a material adverse effect on the
Company's business, results of operations or financial condition.
 
    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, the Environmental Laws). Based upon the
Company's experience to date, as well as certain indemnification agreements
obtained in connection with the Company's acquisitions, 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.
 
    EMPLOYEE AGREEMENTS--Effective December 31, 1997, the Company terminated the
employment of two shareholders upon the closing of the Kolmar Acquisition (Note
14). The shareholders will receive lump sum payments totaling $553,700, plus
benefits.
 
    MANAGEMENT SERVICE AGREEMENTS--Pursuant to a Management Services Agreement
with The Gordon+Morris Group (G+MG), the Company paid G+MG $800,000 upon closing
of the Kolmar Acquisition and will pay G+MG, in exchange for management
services, (i) an annual fee of $350,000, which is subject to adjustment, and
(ii) up to 2% of the total consideration received or paid in various
transactions. The Company is also a party to a letter agreement with HarbourVest
Partners, LLC (HV), pursuant to which the Company will pay HV, in exchange for
financial and business advisory services, (i) an annual fee of $115,000 and (ii)
1/3 of the fee, under certain conditions, received by G+MG under its Management
Services Agreement with the Company.

14.  SUBSEQUENT EVENTS
 
    As of January 1, 1998, the Company acquired from CCL Industries, all of the
outstanding shares of Kolmar Laboratories, Inc. and the net assets of Kolmar
Canada Inc., (collectively referred to as the Kolmar Group) for $78.0 million,
subject to certain post-closing adjustments. The acquisition has been treated as
a purchase for accounting purposes. Accordingly, the assets acquired and
liabilities assumed have been recorded at their estimated fair values at the
date of acquisition. Assuming the Kolmar Group acquisition had occurred on
January 1, 1997, pro forma net revenue and net loss for OSG for the year ended
December 31, 1997 would have been approximately $213,090,000 and $847,000,
respectively.
 
    The Kolmar Group designs, manufactures, contracts for manufacture and sells
a variety of cosmetics, creams and lotions, and fragrances to retailers and
wholesale distributors principally in the United States, Canada, Mexico and
Australia.
 
    In conjunction with the Kolmar Group acquisition, the Company refinanced all
of its existing indebtedness. Deferred financing costs of $1,111,000 associated
with this indebtedness was written off. The purchase price and the repayment of
existing debt, plus $7.4 million of related fees and expenses were financed
through $30.0 million of borrowings under a senior secured credit facility,
$70.0 million of borrowings under a senior subordinated credit agreement, and
the issuance of 2.093 million shares of the Company's common stock to existing
shareholders of the Company. Loans under the senior secured credit facility and
the senior subordinated credit agreement bore interest at rates of approximately
9.25% and 11.6%, respectively.
 
    On March 3, 1998, the Company repaid indebtedness incurred in conjunction
with the Kolmar Group acquisition, using the proceeds from the issuance of $105
million senior subordinated notes which are due in 2006. Interest on the notes
will accrue from their date of original issuance and will be payable semi-
annually in arrears on March 1 and September 1 of each year, commencing
September 1, 1998, at the rate of 10.875% per annum. The notes are redeemable in
whole or in part, at the option of the Company, on or after March 1, 2003 at the
redemption price of 110.875% of the aggregate principal amount to be redeemed
plus accrued and unpaid interest to the redemption date. In addition, at any
time on or prior to March 1, 2001, the Company, at its option, may redeem up to
35% of the aggregate principal amount of the notes originally issued with the
net cash proceeds of one or more equity offerings at the redemption price plus
accrued and unpaid interest to the redemption date; provided that at least 65%
of the aggregate principal amount of the notes originally issued remains
outstanding immediately after such redemption. The notes are unsecured senior
subordinated obligations of the Company and will be subordinated in right of
payment to all existing and future senior debt of the Company.
 
   
15.  SUPPLEMENTAL GUARANTOR INFORMATION
    
 
   
    The payment obligations of the Company under the Notes are to be 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 Subsidiary 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 audited condensed

                     INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
THE COMPANY
 
    Section 145 of the General Corporation Law of the State of Delaware (the
"Delaware Corporation Law") empowers a Delaware corporation to indemnify any
persons who are, or are threatened to be made, parties to any threatened,
pending or completed legal action, suit or proceeding, whether civil, criminal,
administrative or investigative (other than an action by or in the right of such
corporation), by reason of the fact that such person is or was an officer,
director, employee or agent of such corporation, or is or was serving at the
request of such corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise. The
indemnity may include expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by such person in
connection with such action, suit or proceeding, provided that such officer or
director acted in good faith and in a manner he reasonably believed to be in or
not opposed to the corporation's best interests, and, for criminal proceedings,
had no reasonable cause to believe his conduct was unlawful. A Delaware
corporation may indemnify officers and directors against expenses (including
attorneys' fees) in an action by or in the right of the corporation under the
same conditions, except that no indemnification is permitted without judicial
approval if the officer or director is adjudged to be liable to the corporation.
Where an officer or director is successful on the merits or otherwise in the
defense of any action referred to above, the corporation must indemnify him
against the expenses which such officer or director actually and reasonably
incurred.
 
    Article Seventh of the Certificate of Incorporation of the Company, as
amended, a copy of which is filed as Exhibit 3.1 to the Registration Statement,
allows the Company to maintain director and officer liability insurance on
behalf of any person who is or was a director or officer of the Company or such
person who serves or served as director, officer, employee or agent, of another
corporation, partnership or other enterprise at the request of the Company.
Article Seventh of the Company's Certificate of Incorporation, as amended,
provides for indemnification of the officers and directors of the Company, to
the fullest extend permitted by applicable law.
 
    Pursuant to Section 102(b)(7) of the Delaware Corporation Law, Articles
Sixth and Seventh of the Certificate of Incorporation of the Company, as
amended, provide that no director of the Company shall be personally liable to
the Company or its shareholders for monetary damages for any breach of his
fiduciary duty as a director; provided, however, that such clause shall not
apply to any liability of a director (1) for any breach of the Director's duty
of loyalty to the Company or its stockholders, (2) for acts or omissions not in
good faith or which involve intentional misconduct or a knowing violation of the
law, (3) pursuant to Section 174 of the Delaware Corporation Law, or (4) for any
transaction from which the director derived an improper personal benefit.
 
THE GUARANTORS
 
    The Guarantors, Aerosol, Kolmar and Piedmont, are incorporated under the
laws of the States of California, Delaware and Georgia, respectively. As with
the Delaware Corporation Law, the California Corporations Code and the Business
Corporations Code of Georgia authorize a corporation, under certain
circumstances, to indemnify its directors and officers (including to reimburse
them for expenses incurred).
 
    As with the Company's Certificate of Incorporation, as amended, and Bylaws,
each of the Guarantor's organizational documents and Bylaws generally provide
for the indemnification of officers and directors to the fullest extent
permitted by law.

           Securities Act of 1933, as amended (the "Act");
 
       (ii) To reflect in the Prospectus any facts or events arising after the
           effective date of the Registration Statement (or the most recent
           post-effective amendment thereof) which, individually or in the
           aggregate, represent a fundamental change in the information set
           forth in the Registration Statement. Notwithstanding the foregoing,
           any increase or decrease in volume of securities offered (if the
           total dollar value of securities offered would not exceed that which
           was registered) and any deviation from the low or high end of the
           estimated maximum offering range may be reflected in the form of
           prospectus filed with the Commission pursuant to Rule 424(b) if, in
           the aggregate, the changes in volume and price represent no more than
           a 20 percent change in the maximum aggregate offering price set forth
           in the "Calculation of Registration Fee" table in the effective
           Registration Statement.
 
       (iii) To include any material information with respect to the plan of
           distribution not previously disclosed in the Registration Statement
           or any material change to such information in the Registration
           Statement;
 
    (2) That, for the purpose of determining any liability under the Act, each
       such post-effective amendment shall be deemed to be a new registration
       statement relating to the securities offered therein, and the offering of
       such securities at that time shall be deemed to be the initial bona fide
       offering thereof.
 
    (3) To remove from registration by means of a post-effective amendment any
       of the securities being registered which remain unsold at the termination
       of the Offering.
 
                                      II-4
<PAGE>
(b) Insofar as indemnification for liabilities arising under the Act may be
    permitted to directors, officers and controlling persons of the Registrants
    pursuant to the foregoing provisions, or otherwise, the Registrant has been
    advised that in the opinion of the Securities and Exchange Commission such
    indemnification is against public policy as expressed in the Act and is,
    therefore, unenforceable. In the event that a claim for indemnification
    against such liabilities (other than the payment by the Registrants of
    expenses incurred or paid by a director, officer or controlling person of
    the Registrants in the successful defense of any action, suit or proceeding)
    is asserted by such director, officer or controlling person in connection
    with the securities being registered, the Registrants will, unless in the
    opinion of its counsel the matter has been settled by controlling precedent,
    submit to a court of appropriate jurisdiction the question whether such
    indemnification by it is against public policy as expressed in the Act and
    will be governed by the final adjudication of such issue.
 
(c) The undersigned registrants hereby undertake to respond to requests for
    information that is incorporated by reference into the prospectus pursuant
    to Item 4, 10(b), 11 or 13 of this form, within one business day of receipt
    of such request, and to send the incorporated documents by first class mail
    or other equally prompt means. This includes information contained in
    documents filed subsequent to the effective date of the Registration
    Statement through the date of responding to the request.
 
(d) The undersigned Registrants hereby undertake to supply by means of a
    post-effective amendment all information concerning a transaction, and the
    company being acquired involved therein, that was not the subject of and
    included in the Registration Statement when it became effective.
