                  THE EXCHANGE OFFER WILL EXPIRE AT 5:00 P.M.,

                           --------------------------
 
   
    A.P.S.,  Inc., a Delaware corporation  ("APS"), hereby offers (the "Exchange
Offer") upon  the  terms  and  subject  to the  conditions  set  forth  in  this
Prospectus  (the "Prospectus") and  the accompanying Letter  of Transmittal (the
"Letter of Transmittal"),  to exchange  up to  $100,000,000 aggregate  principal
amount  of its  11 7/8%  Senior Subordinated Notes  Due 2006  (the "New Notes"),
which have been  registered under the  Securities Act of  1933, as amended  (the
"Securities Act"), pursuant to a Registration Statement of which this Prospectus
is  a  part, for  a  like principal  amount of  its  outstanding 11  7/8% Senior
Subordinated Notes Due  2006 (the "Existing  Notes" and, together  with the  New
Notes,  the "Notes"). The Existing Notes were originally issued in a transaction
that was  exempt from  registration  under the  Securities  Act and  since  such
issuance  have been resold to (i) qualified institutional buyers in reliance on,
and subject  to  the restrictions  imposed  pursuant  to, Rule  144A  under  the
Securities  Act ("Rule 144A"), (ii) institutional investors that are "accredited
investors" within the meaning  of subparagraph (a)(1), (2),  (3) or (7) of  Rule
501  under the  Securities Act,  and (iii)  non-U.S. persons  outside the United
States of  America in  accordance with  Regulation S  under the  Securities  Act
("Regulation  S"). The  terms of  the New  Notes are  identical in  all material
respects to the terms of  the Existing Notes that  are to be exchanged  therefor
except that the New Notes have been registered under the Securities Act and will
not  bear legends restricting the  transferability thereof, certain registration
rights relating to  the Existing  Notes will  terminate upon  completion of  the
Exchange  Offer, and, if the Exchange Offer is not consummated by July 23, 1996,
the rate at which  the Existing Notes  bear interest will be  12 3/8% per  annum
from  and including July 24, 1996 until  but not including the date the Exchange
Offer is consummated. See "Description of the Notes" and "Registration  Rights."
For federal income tax purposes, an exchange made pursuant to the Exchange Offer
should   not   constitute  a   taxable  exchange.   See  "Certain   Federal  Tax
Consequences."
    
 
   
    Based on  interpretations  by  the  staff of  the  Securities  and  Exchange
Commission (the "Commission" or "SEC"), as set forth in no-action letters issued
to  third parties, APS  believes the New  Notes issued pursuant  to the Exchange
Offer may be  offered for resale,  resold and otherwise  transferred by  holders
thereof  (other than any  such holder that  is an "affiliate"  of APS within the
meaning of  Rule 405  under  the Securities  Act)  without compliance  with  the
registration  and prospectus delivery provisions of the Securities Act, provided
that such  New  Notes are  acquired  in the  ordinary  course of  such  holders'
business,  such holders  are not engaged  in and do  not intend to  engage in, a
distribution of such Notes and such holders have 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 therefore 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.
    
 
   
    SEE  "RISK FACTORS"  ON PAGE  15 FOR A  DESCRIPTION OF  CERTAIN FACTORS THAT
SHOULD BE CONSIDERED IN CONNECTION WITH THE EXCHANGE OFFER AND AN INVESTMENT  IN
THE NEW NOTES OFFERED HEREBY.
    
                             ---------------------
 
THESE  SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
   EXCHANGE COMMISSION OR BY  ANY STATE SECURITIES  COMMISSION NOR HAS  THE
     COMMISSION  OR  ANY  STATE  SECURITIES  COMMISSION  PASSED  UPON THE
       ACCURACY OR ADEQUACY  OF THIS  PROSPECTUS. ANY  REPRESENTATION
                          TO THE CONTRARY IS A CRIMINAL OFFENSE.
                            ------------------------
 
   
                 THE DATE OF THIS PROSPECTUS IS JUNE 12, 1996.
    
<PAGE>
   
    Each  holder of Existing  Notes that desires to  participate in the Exchange
Offer, other than a broker-dealer, must  acknowledge that it is not engaged  in,
and  does  not intend  to engage  in, a  distribution  of 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 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 Existing  Notes where  such Existing  Notes were  acquired by  such
broker-dealer   as  a  result  of  market-making  activities  or  other  trading
activities. As described more fully herein, for  a period of one year after  the
Expiration  Date (as defined herein), APS will make this Prospectus available to
any Participating Broker-Dealer (as defined  herein) for use in connection  with
any such resale. See "The Exchange Offer" and "Plan of Distribution."
    
 
    EXCEPT  AS DESCRIBED IN THE PRECEDING  PARAGRAPH, THIS PROSPECTUS MAY NOT BE
USED FOR AN OFFER TO RESELL, A RESALE OR ANY OTHER RETRANSFER OF NEW NOTES.
 
   
    The Exchange Offer is  not conditioned upon any  minimum number of  Existing
Notes being tendered. The Exchange Offer will expire at 5:00 p.m., New York City
time,  on July 18, 1996, unless extended (the "Expiration Date"). Subject to the
terms and conditions of the Exchange Offer, including the reservation of certain
rights by APS and  the right of  holders of Existing  Notes to withdraw  tenders
prior  to the acceptance  thereof, Existing Notes validly  tendered prior to the
Expiration Date will be accepted on  or promptly after the Expiration Date.  New
Notes  to be  issued in  exchange for properly  tendered Existing  Notes will be
mailed by the Exchange Agent (as  defined herein) promptly after the  acceptance
thereof.  In the event APS terminates the Exchange Offer and does not accept for
exchange any Existing Notes, APS will promptly return the Existing Notes to  the
holders thereof. See "The Exchange Offer."
    
 
    The Notes will mature on January 15, 2006 (the "Maturity Date"). Interest on
the  Notes will accrue from the date of  issue and will be payable on January 15
and July 15 of  each year at a  rate of 11 7/8%  per annum, commencing July  15,
1996.  The Existing  Notes are,  and the  New Notes  will be,  redeemable at the
option of APS at any time on or after January 15, 2001, in whole or in part,  at
the  redemption prices  set forth herein,  plus accrued and  unpaid interest, if
any, to the date of  redemption. In addition, up to  an aggregate of 33 1/3%  of
the original aggregate principal amount of the Notes may be redeemed at any time
prior  to January 15,  1999, at the option  of APS, with the  proceeds of one or
more public  offerings by  APS  Holding Corporation  ("Holding") of  its  common
stock,  at a redemption price  of 111.875% of the  principal amount thereof plus
accrued and  unpaid interest,  if  any, to  the  date of  redemption;  PROVIDED,
HOWEVER,  that after giving effect  to any such redemption,  at least 66 2/3% of
the original aggregate principal amount of the Notes remain outstanding. In  the
event  of a Change of Control (as defined herein) occurring prior to January 15,
2001, the Notes will be subject to redemption, at the option of APS, in whole or
in part, at  a redemption price  equal to the  sum of (i)  the principal  amount
thereof,  plus  (ii)  the Applicable  Premium  (as defined  herein),  plus (iii)
accrued and unpaid interest, if any, to the date of redemption. In the event  of
a  Change of Control occurring at any time,  holders of the Notes will also have
the right to require APS  to repurchase all or part  of the Notes at a  purchase
price  in cash equal  to 101% of  the principal amount  thereof plus accrued and
unpaid interest, if any, to the date of purchase. There can be no assurance that
APS will have the financial resources necessary to repurchase the Notes in  such
circumstances.  See  "Description  of  the  Notes  --  Optional  Redemption" and
"Description of the Notes -- Change of Control."
 
    The Existing Notes are, and the New Notes will be, unsecured obligations  of
APS  and subordinated  in right  of payment  to all  existing and  future Senior
Indebtedness of APS  (as defined herein).  The Existing Notes  are, and the  New
Notes  will  be,  guaranteed on  a  senior  subordinated basis  by  Holding (the
"Holding Guarantee") and each of its existing and future Restricted Subsidiaries
(as  defined  herein)  other  than  APS  (each  such  guarantee,  a  "Restricted
Subsidiary Guarantee" and each
 
                                       2

such  guarantor, a "Restricted Subsidiary Guarantor"). The Holding Guarantee and
Restricted Subsidiary Guarantees  rank subordinate  in right of  payment to  all
existing  and  future Senior  Indebtedness of  Holding  (as defined  herein) and
Senior Indebtedness of the Restricted Subsidiary Guarantors (as defined herein),
respectively, including  guarantees  of the  New  Credit Agreement  (as  defined
herein). The obligations of APS under the New Credit Agreement are guaranteed by
Holding and certain of the subsidiaries of APS and are secured by pledges of the
capital   stock  of  APS  and  such   subsidiaries,  by  security  interests  in
substantially all of  their personal  property and  by mortgages  on certain  of
their owned real property.
 
    There  has not previously been  any public market for  the Existing Notes or
the New Notes.  APS does  not intend  to list the  New Notes  on any  securities
exchange  or  to seek  approval for  quotation  through any  automated quotation
system. There can be no assurance that  an active market for the New Notes  will
develop.  See  "Risk Factors  --  Absence of  a  Public Market  for  the Notes."
Moreover, to the  extent that Existing  Notes are tendered  and accepted in  the
Exchange  Offer, the  trading market,  if any,  for untendered  and tendered but
unaccepted Existing Notes could be adversely affected.
 
    APS will not  receive any proceeds  from the Exchange  Offer, but will  bear
certain  offering expenses pursuant to the Registration Agreement, dated January
19, 1996 (the "Registration Agreement"),  among APS and the original  purchasers
of  the Existing  Notes. The  Exchange Offer is  intended to  satisfy certain of
APS's obligations under the Registration Agreement, including the obligation  to
register  the  exchanged  Existing  Notes under  the  Securities  Act.  Upon the
completion of the Exchange Offer, certain special rights under the  Registration
Agreement  will terminate  with respect  to Existing  Notes, and  holders of New
Notes will  not  be  entitled  to  such  rights.  See  "The  Exchange  Offer  --
Termination  of  Certain  Rights."  No  dealer  manager  is  being  utilized  in
connection with the Exchange Offer.

                               PROSPECTUS SUMMARY
 
    THE FOLLOWING SUMMARY IS QUALIFIED IN ITS ENTIRETY BY, AND SHOULD BE READ IN
CONJUNCTION  WITH,  THE  MORE  DETAILED  INFORMATION  AND  FINANCIAL STATEMENTS,
INCLUDING  THE  RELATED  NOTES,  APPEARING  ELSEWHERE  IN  THIS  PROSPECTUS   OR
INCORPORATED  HEREIN BY  REFERENCE. UNLESS  THE CONTEXT  OTHERWISE REQUIRES, THE
TERM "COMPANY"  AS  USED  IN THIS  PROSPECTUS  MEANS  HOLDING AND  APS  AND  ITS
SUBSIDIARIES.  THE PRINCIPAL  EXECUTIVE OFFICES  OF THE  COMPANY ARE  LOCATED AT
WORLD HOUSTON PLAZA, 15710 JOHN F. KENNEDY BOULEVARD, SUITE 700, HOUSTON,  TEXAS
77032-2347, AND ITS TELEPHONE NUMBER IS (713) 507-1100.
 
                                  THE COMPANY
 
   
    The  Company is  a leading  warehouse distributor  of automotive replacement
parts in  the  United  States,  supplying  over  1,900  parts  stores  owned  by
independent  operators ("jobbers") and approximately 325 Company-owned stores as
of April 25, 1996. The Company  principally serves the wholesale segment of  the
automotive  parts aftermarket. Through the  Company's network of 35 distribution
centers in  30 states,  the  Company offers  over  160,000 stock  keeping  units
("SKUs"),  including a broad  array of nationally  recognized replacement parts,
tools, equipment, supplies and accessories under its Big A-Registered Trademark-
brand name as well as manufacturers' brands and, for a limited time through  the
distribution   centers   owned  by   Parts,   Inc.  ("PI"),   under   the  Parts
Plus-Registered Trademark-  group of  brand names.  See "  -- The  Acquisition,"
"Risk  Factors -- Realization  of Benefits from  the Acquisition; Integration of
PI" and "Business -- Company Overview." In  addition, as of April 25, 1996,  the
Company  operated more than  250 Installers' Service  Warehouses ("ISWs"), which
directly serve the  needs of  the professional  installer by  stocking a  select
number  of high demand products and emphasizing availability and quick delivery.
The Company had net sales and  income before interest expense and income  taxes,
plus  depreciation  and  amortization  ("EBITDA") of  $603.7  million  and $38.7
million, respectively, for  the fiscal year  ended January 27,  1996 and  $217.6
million  and $11.9 million,  respectively, for the three  months ended April 25,
1996. Excluding  the $11.2  million asset  impairment and  restructuring  charge
recorded  by the Company in the fourth quarter of fiscal 1996, the Company would
have had EBITDA of $50.0 million for the fiscal year ended January 27, 1996. See
"Management's Discussion  and Analysis  of Financial  Condition and  Results  of
Operations -- Results of Operations" in Holding's Annual Report on Form 10-K for
the  fiscal year  ended January  27, 1996  (the "Form  10-K"), and  in Holding's
Quarterly Report on Form 10-Q for the  fiscal quarter ended April 25, 1996  (the
"Form  10-Q"), each of which is  incorporated herein by reference, and "Selected
Historical Consolidated Financial Information of APS Holding Corporation."
    
 
   
    The Company's Big A  program offers a number  of benefits to the  associated
jobbers  that participate  in the  program, including  (i) a  broad selection of
product  lines;  (ii)  brand  name  identity,  including  national   advertising
programs;  (iii) access to flexible purchasing programs; (iv) overnight delivery
of parts; and (v) a comprehensive  package of services, including assistance  in
marketing,  cataloging, inventory  control, accounting,  management and employee
training. Approximately  two-thirds  of  the Company's  associated  jobbers  and
Company-owned  stores are located  in communities with  populations of less than
25,000 people. The Company believes that jobbers located in smaller  communities
are  well suited  to the Big  A program  because the customer  base within these
communities generally is not large enough to support the investment necessary to
enable a jobber  to obtain  on its own  the benefits  of the Big  A program.  In
contrast,  ISWs  target customers  in  larger metropolitan  areas  typically not
served by the Company's associated  jobbers or Company-owned stores by  focusing
on  a select number of high demand products (typically undercar products such as
chassis, suspension, steering and brake parts) and emphasizing availability  and
quick delivery.
    
 
                                THE ACQUISITION
 
   
    Pursuant to a purchase agreement dated as of December 5, 1995 (the "Purchase
Agreement"),  on January 25, 1996 (the "Acquisition Closing Date"), APS acquired
all of the outstanding  stock of PI, an  automotive parts distributor, from  GKN
Parts  Industries Corporation ("GKN Parts") for a cash closing purchase price of
$79.7  million  (the  "Acquisition"),  which  purchase  price  was  adjusted  to
    
 
                                       4
<PAGE>
   
$74.9  million after  the closing.  As of the  Acquisition Closing  Date, the PI
distribution network was comprised  of approximately 850  parts stores owned  by
PI's  associated jobbers and more than  125 company-owned stores operating under
the Parts Plus group of marks, which were serviced through PI's 14  distribution
centers.  As of the  Acquisition Closing Date, PI's  customer base was primarily
located in markets where the Company had a relatively minor presence,  including
Arkansas,  Oklahoma,  Texas,  Tennessee,  Kentucky,  Mississippi,  Alabama, West
Virginia and Michigan.  Based on the  Company's review of  PI's store base,  the
Company  believes that, at the time of the Acquisition, there was less than a 5%
overlap between  the Company's  and PI's  associated jobbers  and  company-owned
stores.  The Company  believes that  opportunities exist  to achieve significant
ongoing purchasing and other  cost savings in  connection with the  Acquisition,
including  through volume discounts from suppliers,  the closure (as of the date
of this Prospectus) of four of the Company's distribution centers (including two
PI distribution  centers) and  the anticipated  closure of  seven additional  PI
distribution  centers,  and  the  consolidation  of  these  operations  into the
combined companies' remaining facilities. PI had net sales and EBITDA of  $224.8
million  and $5.0 million,  respectively, for the year  ended December 31, 1995.
See "Business" in the Form 10-K, which is incorporated herein by reference,  and
"Risk  Factors -- Realization  of Benefits from  the Acquisition; Integration of
PI," "Pro Forma Combined  Condensed Statement of  Operations" and the  Financial
Statements  of PI and the related notes  thereto for the year ended December 31,
1995.

                                              for a like principal amount of Existing Notes.

                                              Based  on interpretations by  the staff of the
                                              Commission, as set forth in several  no-action

                                              believes that the New Notes issued pursuant to

                                              its own account in exchange for Existing Notes
                                              pursuant   to   the   Exchange   Offer    must

                                              not be obligated to repurchase such New  Notes
                                              if  it has exercised its  rights to redeem all

                                              APS   will   have   the   financial  resources
                                              necessary or that  it will be  able to  obtain

                                              to cause such Shelf Registration Statement  to
                                              become  effective  generally  within  30  days
                                              after the  date on  which APS  is required  to
                                              file  the Shelf Registration Statement, and to

                                              Registration Statement is filed at the request
                                              of an Initial Purchaser). Upon consummation of
                                              the Exchange Offer, APS generally will have no
                                              further obligation  to register  the  Existing
                                              Notes. See "Registration Rights."
 
TERMINATION OF CERTAIN RIGHTS...............  Holders  of New Notes will  not be entitled to
                                              certain   rights   under   the    Registration
                                              Agreement,  including the right to require APS
                                              to file a registration statement with  respect
                                              to   the  New  Notes,  and  to  file  a  Shelf
                                              Registration  Statement,  except  in   certain
                                              limited circumstances. See "The Exchange Offer
                                              -- Termination of Certain Rights."
 
ABSENCE OF A PUBLIC MARKET                    The New Notes will be new securities for which
 FOR THE NEW NOTES..........................  there  currently  is no  market.  Although the
                                              Initial Purchasers have  informed the  Company
                                              that they currently intend to make a market in
                                              the  New Notes,  they are not  obligated to do
                                              so,  and  any  such   market  making  may   be
                                              discontinued   at  any  time  without  notice.
                                              Accordingly, there can be  no assurance as  to
                                              the development or liquidity of any market for
                                              the  New Notes. The Company does not intend to
                                              apply for  listing of  the  New Notes  on  any
                                              securities  exchange or  for quotation through
                                              the National Association of Securities Dealers
                                              Automated Quotation System.
 
USE OF PROCEEDS.............................  APS will  not receive  any proceeds  from  the
                                              Exchange  Offer. The net  proceeds to APS from
                                              the sale of  the Existing Notes  were used  to
                                              pay  the $79.7 million  closing purchase price
                                              for PI  (which  was subsequently  adjusted  to
                                              $74.9  million)  and to  pay related  fees and
                                              expenses, and the remainder was used to  repay
                                              certain bank borrowings under the Prior Credit
                                              Agreement (as defined herein).

            SUMMARY FINANCIAL INFORMATION AND PRO FORMA INFORMATION
 
   
    The following tables present summary historical financial data derived  from
the consolidated financial statements of Holding and summary unaudited pro forma
combined  data of  Holding and  PI for  the periods  indicated. PI's  results of
operations for  the two  days between  the consummation  of the  Acquisition  on
January  25,  1996  and  Holding's  fiscal year  end  on  January  27,  1996 are
immaterial to Holding's results of operations for the fiscal year ended  January
27,  1996. The pro forma data was prepared to illustrate, in accordance with SEC
Regulation S-X, Article 11, the estimated effect of the Acquisition and  related
transactions,  including the issuance of the Existing Notes and borrowings under
the New Credit  Agreement, as if  the Acquisition and  related transactions  had
occurred  as of  January 29,  1995. The pro  forma data  does not  purport to be
indicative of the results of operations or financial position of Holding and  PI
that   actually  would  have  been  obtained  if  the  Acquisition  and  related
transactions had  in fact  been completed  as of  such date  or to  project  the
results  of operations or financial  position of Holding for  any future date or
period. The  information  should  be  read  in  conjunction  with  "Management's
Discussion  and Analysis of  Financial Condition and  Results of Operations" and
the Consolidated  Financial  Statements of  Holding  and related  notes  thereto
included  in the  Form 10-K  and the  Form 10-Q,  each of  which is incorporated
herein by reference, and "Pro Forma Combined Condensed Statement of  Operations"
and the Financial Statements of PI and the related notes thereto with respect to
the fiscal year ended December 31, 1995.

    (1)  The pro forma  combined financial data have  been prepared assuming the
retention of all  of the  Company's and  PI's sales  following the  Acquisition.
Management  anticipates, however,  that it  will retain  significantly less than
100% of  PI's sales  as a  result of  the expected  loss of  certain  associated
jobbers  and the closure of certain company-owned stores. The lower retention of
sales will result in lower operating results of the combined companies than  are
reflected  in such  pro forma combined  financial data. See  "Pro Forma Combined
Condensed Statement of Operations."
 
    (2) For  purposes  of the  pro  forma  data, PI's  historical  statement  of
operations  for the fiscal  year ended December  31, 1995 was  combined with the
Company's historical statement of operations  for the fiscal year ended  January
27,1996.  Pro forma  adjustments to  the combined  results of  operations of the
Company and PI arising as a result of the Acquisition include:

</TABLE>
    
 
        (a) Consists primarily of  estimated savings resulting from  incremental
    purchasing economies that the Company believes can be realized in connection
    with  the Acquisition, based on arrangements the Company negotiated with its
    major suppliers following the Acquisition.
 
   
        (b) Consists primarily of estimated savings resulting from reductions in
    payroll, benefits  and occupancy  costs as  the result  of the  closure  and
    consolidation  of eleven  of the  Company's distribution  centers (including
    nine  PI   distribution   centers)   and  the   consolidation   of   certain
    administrative functions.
    
 
   
        (c)  Adjustments have been made (i)  to depreciation and amortization to
    conform PI's accounting policies and practices to those of the Company, (ii)
    to interest  expense to  reflect  the issuance  of  the Existing  Notes  and
    borrowings  under the  New Credit  Agreement, and  (iii) to  reflect the tax
    impact of the above adjustments.
    
 
    There can be no assurance that the  Company will in fact realize any of  the
cost  savings  reflected in  these  adjustments, or  that  expenses will  not be
materially higher than the levels reflected in the pro forma data.
 
   
    The Acquisition  was accounted  for by  the purchase  method of  accounting,
pursuant  to which the purchase price  was allocated among the acquired tangible
and intangible assets and  assumed liabilities in  accordance with estimates  of
their fair values on the date of the Acquisition.
    
 
    (3)  Operating  income for  fiscal 1996  reflects the  impact of  an $11,224
pre-tax charge related to a  facility rationalization and restructuring  program
undertaken  in conjunction  with the Acquisition,  the adoption  of Statement of
Financial Accounting Standards No. 121 (entitled, "Accounting for the Impairment
of Long-lived Assets and  for Long-lived Assets to  be Disposed of") ("SFAS  No.
121")  relating to  the impairment  and disposal  of long-lived  assets, and the
write-down of certain assets.
 
    (4) Other income (expense) in fiscal  1993 includes a non-recurring gain  on
pension curtailment of $3,288.
 
    (5)  The benefit  for income taxes  in fiscal 1995  includes a non-recurring
benefit of $14,802, recognized as a  result of the Company's ability to  utilize
its net operating loss carryforwards.
 
    (6) Excluding the $11,224 asset impairment and restructuring charge recorded
by  the Company in the fourth quarter of fiscal 1996, the Company would have had
EBITDA of $49,957 for the fiscal year ended January 27, 1996. EBITDA  represents
the  sum of income  before interest expense and  income taxes, plus depreciation
and amortization. EBITDA should not be construed as a substitute for income from
operations, net income or cash flow  from operating activities, for the  purpose
of  analyzing the Company's  operating performance, financial  position and cash
flows. The Company has presented EBITDA because it is commonly used by investors
to analyze and compare  companies on the basis  of operating performance and  to
determine a company's ability to service debt.
 
    (7)  For  purposes of  computing  the ratio  of  earnings to  fixed charges,
earnings consist of income  from continuing operations  before income taxes  and
fixed  charges.  Fixed  charges  include interest  expense  and  the  portion of
operating rents that is deemed representative of an interest factor.

    Holders of Existing Notes who do not exchange them for New Notes pursuant to
the  Exchange  Offer will  continue  to be  subject  to certain  restrictions on
transfer of  such Existing  Notes. In  general, the  Existing Notes  may not  be
reoffered   or  resold  by  their  holders   except  pursuant  to  an  effective
registration statement under  the Securities  Act or pursuant  to an  applicable
exemption  from such  registration, and  the Existing  Notes are  legended to so
restrict their transfer. Based  on interpretations by the  staff of the SEC,  as
set  forth in  no-action letters issued  to third parties,  the Company believes
that each holder (other than any holder who is an "affiliate" of APS within  the
meaning  of Rule 405 under the Securities Act) who duly exchanges Existing Notes
for New Notes  in the  Exchange Offer  will receive  New Notes  that are  freely
tradeable under the Securities Act, PROVIDED THAT such New Notes are acquired in
the  ordinary  course of  such holder's  business  and that  such holder  is not
engaged in, and does not intend to  engage in, a distribution of such New  Notes
and  has no arrangement or  understanding with any person  to participate in the
distribution of  such  New Notes.  The  SEC,  however, has  not  considered  the
Exchange  Offer in the context of a no-action letter, and therefore there can be
no assurance that the staff of the  SEC would make a similar determination  with
respect  to  the  Exchange Offer  as  in  such other  circumstances.  Holders of
Existing Notes who participate in such Exchange Offer should be aware,  however,
that,  except in the case of certain  broker-dealers as described below, if they
accept New Notes in the Exchange Offer for the purpose of engaging in  secondary
resales,  such  New  Notes  may  not be  publicly  reoffered  or  resold without
complying with  the registration  and prospectus  delivery requirements  of  the
Securities  Act. Each broker-dealer that receives  New Notes for its own account
in exchange for Existing Notes, where such Existing 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 "The Exchange Offer," "Description of the
Notes -- Registration Covenant; Exchange Offer" and "Plan of Distribution."
    
 
    The  Existing Notes may  be sold pursuant  to the restrictions  set forth in
Rule 144A,  Regulation  D under  the  Securities  Act or  Regulation  S  without
registration under the Securities Act.
 
LEVERAGE; RESTRICTIVE COVENANTS
 
   
    The  Company  incurred  significant  indebtedness  in  connection  with  the
financing of the Acquisition. As a  result, the Company is highly leveraged  and
has  substantial repayment obligations as well as significant interest expenses.
As of April  25, 1996,  the Company's total  indebtedness (including  short-term
debt)  and its ratio  of total indebtedness to  total capitalization were $304.3
million and 70.8%, respectively. See "Capitalization." The Amended and  Restated
Credit  Agreement, dated  as of  the Acquisition  Closing Date  (the "New Credit
Agreement"), among APS, as borrower, Holding and certain of the subsidiaries  of
APS,  as guarantors, and a syndicate of banks led by Chemical Bank ("Chemical"),
provides for a $65 million term loan  facility (the "Term Loan Facility") and  a
$235  million revolving credit  facility (the "Revolving  Credit Facility"). The
New Credit Agreement requires the  Company to make quarterly principal  payments
on the term loans thereunder. Scheduled annual term loan principal payments will
equal  $13 million  in 1996, $15  million in 1997,  $17 million in  1998 and $20
million in 1999, and all outstanding  revolving credit loans will become due  on
December 31, 2000. See "Description of New Credit Agreement."
    
 
    The  Company's ability to  make scheduled payments  of principal or interest
on, or  to refinance,  its  indebtedness will  depend  on its  future  operating
performance  and cash flow, which are subject to prevailing economic conditions,
prevailing interest rate levels, and financial, competitive, business and  other
factors  beyond its control. The degree to  which the Company is leveraged could
have
 
                                       15
<PAGE>
   
important consequences to the holders of the Notes, including: (i) the Company's
future ability  to obtain  additional  financing for  working capital  or  other
purposes  may be limited; (ii) a substantial  portion of the Company's cash flow
from operations will be  dedicated to the payment  of principal and interest  on
its indebtedness, thereby reducing funds available for operations; (iii) certain
of  the  Company's borrowings,  including all  borrowings  under the  New Credit
Agreement, will be at variable rates of interest, which could cause the  Company
to  be vulnerable to increases  in interest rates; (iv)  all of the indebtedness
incurred in connection with  the New Credit Agreement  will become due prior  to
the  time any principal payment on the Notes  is due; and (v) the Company may be
more vulnerable  to economic  downturns and  may be  limited in  its ability  to
withstand  competitive pressures. The Company  has entered into certain interest
rate  protection  arrangements,  which  are  a  type  of  financial   derivative
instrument  and cover a portion of the borrowings under the New Credit Agreement
and are for a limited duration.
    
 
    The Company  believes  that, based  upon  anticipated levels  of  operations
(assuming  the timely  integration of PI's  business into that  of the Company's
business; see "-- Realization of  Benefits from the Acquisition; Integration  of
PI"),   it  should  be  able  to  meet  its  regularly  scheduled  debt  service
obligations, including principal  repayments under  the Term  Loan Facility  and
interest  payments  on  the Notes  when  due,  prior to  maturity  of  the loans
outstanding under the Revolving Credit Facility. If the Company cannot  generate
sufficient  cash flow  from operations  to meet  such obligations,  however, the
Company might be  required to  refinance its  debt or  to dispose  of assets  to
obtain  funds  for such  purpose. In  addition, the  Company currently  does not
expect to generate sufficient cash flow to fund the repayment of loans under the
Revolving Credit  Facility  that will  become  due  upon the  maturity  of  such
facility  on December 31,  2000 and, accordingly,  expects that it  will seek to
refinance such  amounts prior  to  such maturity.  There  is no  assurance  that
refinancings  or asset dispositions  could be effected  on satisfactory terms or
would be permitted by the terms of the New Credit Agreement or the Indenture.
 
    The New  Credit  Agreement  and the  Indenture  contain  numerous  operating
covenants  that limit the discretion of the Company's management with respect to
certain business  matters. These  covenants place  significant restrictions  on,
among other things, the ability of the Company to incur additional indebtedness,
to  create liens or  other encumbrances, to  make certain payments, investments,
loans and guarantees and  to sell or  otherwise dispose of  assets and merge  or
consolidate  with another entity. See "Description  of New Credit Agreement" and
"Description of the Notes -- Certain  Covenants." The New Credit Agreement  also
contains  a  number of  financial  covenants that  require  the Company  to meet
certain financial ratios and tests,  including maintenance of the Company's  net
worth  and  maintenance of  consolidated fixed  charge  to interest  expense and
consolidated leverage ratios. A failure to comply with the obligations contained
in the New Credit Agreement or the Indenture could result in an event of default
under the New Credit Agreement or an Event of Default under the Indenture  that,
if  not cured  or waived,  could permit  acceleration of  the relevant  debt and
acceleration of debt under other instruments that may contain cross-acceleration
or cross-default provisions.  Other indebtedness  of the  Company could  contain
amortization  and other prepayment provisions,  or financial or other covenants,
more restrictive than those applicable to the Notes.
 
SUBORDINATION OF THE NOTES AND THE GUARANTEES; ASSET ENCUMBRANCES
 
    The payment of principal of, premium, if any, and interest on, and any other
amounts owing in respect of, the Notes  is subordinated to the prior payment  in
full  in cash or cash equivalents of all existing and future Senior Indebtedness
of APS,  which  includes  all  indebtedness  under  the  New  Credit  Agreement.
Therefore,   in  the   event  of   the  bankruptcy,   liquidation,  dissolution,
reorganization or any similar proceeding regarding  APS, the assets of APS  will
be  available to pay obligations on the  Notes only after Senior Indebtedness of
APS has been paid  in full in cash  or cash equivalents or  in any other  manner
acceptable  to the  holders of  such Senior Indebtedness,  and there  may not be
sufficient assets remaining to pay  amounts due on all or  any of the Notes.  In
addition,  APS may not pay principal of, premium,  if any, or interest on or any
other amounts owing in respect of the Notes or make any deposit for the  purpose
of  the discharge of its liabilities under the Indenture and may not repurchase,
 
                                       16
<PAGE>
redeem or otherwise retire any Notes, if  any Senior Indebtedness of APS is  not
paid  when due or any  other default on such  Senior Indebtedness occurs and the
maturity of such Senior Indebtedness is accelerated in accordance with its terms
unless, in  either  case,  such  default  has been  cured  or  waived  and  such
acceleration  has been rescinded or such  Senior Indebtedness has been repaid in
full. In addition, during the continuance  of any default (other than a  default
described   in  the  preceding  sentence)  with  respect  to  Designated  Senior
Indebtedness of  APS (as  defined herein),  as a  result of  which the  maturity
thereof  may then be  accelerated immediately, APS may  be prevented from making
any payments on the Notes for a specified period of time unless such default  is
no longer continuing, the blockage of payments on the Notes is rescinded or such
indebtedness  has  been  repaid  in  full.  See  "Description  of  the  Notes --
Subordination of Notes."
 
    The Note  Guarantees are  subordinated  to the  existing and  future  Senior
Indebtedness of Holding and the Senior Indebtedness of the Restricted Subsidiary
Guarantors,  as  applicable,  including  their  respective  guarantees  of APS's
obligations under the  New Credit Agreement.  See "Description of  the Notes  --
Subordination of Note Guarantees; Release of Restricted Subsidiary Guarantees."
 
    Neither  the  Notes  nor the  Note  Guarantees  are secured  by  any  of the
Company's assets. The  obligations of  APS under  the New  Credit Agreement  are
secured  by pledges of the capital stock of APS and certain of its subsidiaries,
by a security interest in substantially all of the personal property of APS  and
such subsidiaries, including intangible assets, such as licenses, trademarks and
customer lists, and by mortgages on certain of their owned real property. If APS
becomes insolvent or is liquidated, or if payment under the New Credit Agreement
is  accelerated, the lenders under the New Credit Agreement would be entitled to
exercise the remedies  available to a  secured lender under  applicable law  and
pursuant  to the  New Credit  Agreement. Accordingly,  such lenders  will have a
prior claim on such assets of APS and such subsidiaries.
 
    Holding  is  a  holding  company  with  no  independent  operations  and  no
significant  assets  other  than its  ownership  of  the capital  stock  of APS.
Holding, therefore,  is  dependent  upon  the  receipt  of  dividends  or  other
distributions  from  APS  to  fund any  obligations  that  it  incurs, including
obligations under  the  Holding Guarantee.  The  New Credit  Agreement  contains
restrictions  on  distributions  from APS  to  Holding, other  than  for certain
specified purposes. See "Description of  New Credit Agreement." Accordingly,  if
APS  should at any time be unable to  pay interest on or principal of the Notes,
it is unlikely  that it will  be permitted  to distribute to  Holding the  funds
necessary to enable Holding to meet its obligations under the Holding Guarantee.
 
LIQUIDITY
 
    Since  the  completion of  the Company's  initial  public offering  and debt
refinancing in 1993, the Company has pursued more aggressive acquisition and ISW
expansion programs,  resulting in  increased funding  requirements. The  Company
expects  that  the  principal  sources of  liquidity  for  the  Company's future
operating requirements and business expansion will be cash flows from operations
and borrowings under  the New  Credit Agreement.  In addition,  the Company  has
negotiated   deferred  payment  terms  and   other  changeover  and  acquisition
incentives with its major suppliers in order to offset the costs of  integrating
PI  and to  improve the Company's  liquidity during such  integration. While the
Company expects that  such sources  will provide sufficient  working capital  to
meet the Company's regularly scheduled debt service obligations (which increased
significantly  as a result  of the Acquisition and  related financings) prior to
the maturity  of the  loans  outstanding under  the Revolving  Credit  Facility,
operate  its  business and  finance  the integration  of  PI into  the Company's
distribution network  and the  Company's  currently planned  expansion  efforts,
there  can be  no assurance  that such  sources will  prove to  be sufficient. A
failure to realize  a substantial  portion of  the benefits  of the  Acquisition
within  the  time frame  expected  by the  Company  could result  in significant
additional working  capital requirements.  The Company  expects to  satisfy  its
trade  payables upon  the expiration of  deferred payment terms  using cash flow
from  operations  and  borrowings  under  the  Revolving  Credit  Facility.  The
satisfaction   of  such  trade  payables   could,  depending  on  the  Company's
 
                                       17
<PAGE>
cash  flow  from  operations  at  the  time  of  payment,  significantly  reduce
availability  under the Revolving Credit Facility for other purposes. Borrowings
under the  Revolving  Credit  Facility  are subject  to  the  maintenance  of  a
borrowing base consisting of eligible inventory and accounts receivable.
 
   
    The  Company increased  the total  number of ISW  locations from  150 to 252
during the fiscal  year ended  January 27,  1996, and  to 255  during the  three
months  ended April 25,  1996. The Company plans  to open between  40 and 50 new
ISWs during fiscal 1997. Operating results have experienced and are expected  to
continue  to experience earnings and cash flow  pressure due to the large number
of less mature ISWs and the rapid growth  of the ISW base, the costs of  opening
additional  ISWs and the expiration, generally after  a period of six to fifteen
months, of deferred payment terms extended to the Company in connection with the
opening of new ISW locations.
    
 
REALIZATION OF BENEFITS FROM THE ACQUISITION; INTEGRATION OF PI
 
   
    Full realization  of  the potential  benefits  of the  Acquisition  will  be
dependent  upon a variety  of factors, including (i)  retention of a substantial
portion of PI's sales, particularly  sales to higher volume associated  jobbers;
(ii)  achieving sales  volumes sufficient to  utilize the reductions  in cost of
goods sold (as a  percentage of net sales)  resulting from purchasing  economies
extended to the Company by its suppliers; (iii) achieving significant reductions
in  selling, general and administrative expenses  through the closure (as of the
date  of  this  Prospectus)  of  four  of  the  Company's  distribution  centers
(including  two PI  distribution centers) and  the anticipated  closure of seven
additional PI distribution centers, and  consolidation of these operations  into
the  combined  companies'  remaining  facilities, as  well  as  consolidation of
certain administrative functions; and (iv) obtaining deferred payment terms  and
other  one-time changeover incentives from suppliers  that will be sufficient to
offset certain significant  one-time cash  costs and expenses  that the  Company
incurred  in connection with the Acquisition  and expects to incur in connection
with the integration of PI's business in the Company's business. There can be no
assurance as to  the extent to  which the Company  will be able  to realize  the
potential  benefits of  the Acquisition or  the timing of  any such realization.
Failure to achieve a substantial portion of these benefits within the time frame
expected by  the Company  could materially  and adversely  affect the  Company's
future  results of operations and financial position. See "Business" in the Form
10-K and  "Management's  Discussion  and Analysis  of  Financial  Condition  and
Results of Operations" in the Form 10-Q, each of which is incorporated herein by
reference, and "Pro Forma Combined Condensed Statement of Operations" (including
the notes thereto).
    
 
    RETAINING A SUBSTANTIAL PORTION OF PI'S SALES.  The Company believes that it
will  retain significantly  less than  100% of  PI's sales  and that  the actual
amount of sales that  will be retained  will not be known  until the process  of
converting  PI's  distribution  centers,  associated  jobbers  and company-owned
stores to the Big  A program has been  completed. The Company's competitors  may
seek  to obtain certain of  PI's or the Company's  existing customers during the
period of  the  integration of  PI,  including  through the  use  of  purchasing
discounts  or  other incentives.  The  Company's assessment  of  the anticipated
benefits of the  Acquisition assumes retention  of at least  a majority of  PI's
sales,  particularly from PI's larger customers. While substantially all of PI's
larger customers have indicated to the  Company that they intend to change  over
to  the Big  A program,  there can  be no  assurance that  such changeovers will
actually occur. If the Company retains  a materially smaller percentage of  PI's
sales,  particularly those  made to larger  customers, than it  has assumed, the
benefits of the Acquisition  to the Company could  be materially diminished  and
its future results of operations could be materially and adversely affected.
 
   
    OBTAINING   SIGNIFICANT  PURCHASING  ECONOMIES.    The  Company's  estimates
regarding the purchasing economies that it expects to achieve as a result of the
Acquisition are based upon  a variety of  assumptions derived from  arrangements
that  the Company  has negotiated with  its major suppliers  and its preliminary
estimates regarding sales volumes over the next several years. These assumptions
may not prove to be accurate and are  subject to a number of factors beyond  the
Company's  control, including those described under "-- Product Demand," as well
as the level of retention  by the Company of  sales from existing PI  customers.
The volume discounts that were extended to the
    
 
                                       18
<PAGE>
   
Company  by  its suppliers  at the  time of  the Acquisition  will be  earned as
additional inventory is purchased by the Company subsequent to the  Acquisition.
The  Company has also  negotiated additional incentives from  its suppliers as a
result of, among  other things, the  consolidation of PI  and APS product  lines
into single suppliers. The aggregate amount of such purchasing economies will be
dependent  upon the amount and character of  PI's sales that the Company is able
to retain. A failure by the  Company to obtain significant purchasing  economies
could  materially diminish  the benefits of  the Acquisition  and materially and
adversely affect the Company's future results of operations.
    
 
   
    ACHIEVING SIGNIFICANT  REDUCTIONS  IN SELLING,  GENERAL  AND  ADMINISTRATIVE
EXPENSES.   The  Company's estimates regarding  cost savings  resulting from the
closure  (as  of  the  date  of  this  Prospectus)  of  four  of  the  Company's
distribution centers (including two PI distribution centers) and the anticipated
closure  of seven additional PI distribution centers are based upon a variety of
assumptions, including with respect to the cost of terminating leases for and/or
subleasing the  closed  properties,  the magnitude  of  the  Company's  employee
severance  obligations and the  number of additional  employees that the Company
will add to the remaining distribution centers following the closure of such  PI
and  Company facilities. The Company's assumptions  may not prove to be accurate
and are subject to a number of factors beyond its control.
    
 
   
    OBTAINING SUPPLIER INCENTIVES TO  OFFSET ONE-TIME COSTS  AND EXPENSES.   The
Company  expects to incur  significant costs and expenses  during fiscal 1997 in
connection with the Acquisition  and the integration of  PI's business into  the
Company's  distribution network, including those associated with the closure and
consolidation  of   certain   PI  distribution   centers,   employee   severance
obligations,   product  changeovers  and   customer  retention  incentives.  The
estimated costs to close certain  PI distribution centers and terminate  certain
PI  employees have been recognized as a  liability assumed in the purchase of PI
and included  in the  allocation of  cost  pursuant to  the purchase  method  of
accounting  for business combinations. APS  has negotiated changeover incentives
and deferred payment terms from its major suppliers in order to help offset  its
product changeover and customer retention expenses and reduce the impact of such
costs  and  expenses  on  its operating  results  and  liquidity;  no assurance,
however, can  be given  that such  incentives and  terms will  be sufficient  to
substantially  offset  such  costs  and expenses.  If  the  integration  of PI's
business with the business of  the Company is more  costly or takes longer  than
anticipated,  the  Company's  results  of  operations  could  be  materially and
adversely affected.
    
 
   
    The Company  took a  pre-tax asset  impairment and  restructuring charge  of
$11.2  million in the fourth quarter of  fiscal 1996, which primarily related to
closures and consolidations of certain APS facilities, the adoption of SFAS  121
relating to the impairment and disposal of long-lived assets, and the write-down
of  certain intangible and other assets.  The Company also took an extraordinary
pre-tax charge of $3.9 million in  connection with the write-off of  unamortized
debt  issuance costs related to the substantive modification of the terms of the
Company's prior credit  agreement with  a lending syndicate  (the "Prior  Credit
Agreement")  as a  result of  the execution of  the New  Credit Agreement, which
charge was accounted for as an extinguishment of debt. The Company also incurred
substantial debt issuance costs in connection with the issuance of the  Existing
Notes  and  the  execution  of  the  New  Credit  Agreement.  See  "Management's
Discussion and Analysis of Financial Condition and Results of Operations" in the
Form 10-K  and  in the  Form  10-Q, each  of  which is  incorporated  herein  by
reference, and "Pro Forma Combined Condensed Financial Statement of Operations."
    
 
COMPETITION
 
    The  Company  operates  in  a highly  competitive  environment.  It competes
directly and indirectly with numerous distributors, retailers and  manufacturers
of  automotive aftermarket products,  some of which  distribute in channels that
may be expanding in terms of market share relative to the channels in which  the
Company distributes its products. In addition, some of the Company's current and
potential  competitors are larger, may have  greater financial resources and may
be less leveraged than  the Company. Furthermore, particularly  in light of  the
trend in the automotive parts industry
 
                                       19
<PAGE>
toward  increasing  consolidation  at  the  warehouse  and  jobber  levels,  the
Company's financial performance may be  significantly affected by the  Company's
ability  to compete successfully for  associated jobber customers, and otherwise
take advantage of consolidation opportunities and other industry trends.
 
PRODUCT DEMAND
 
   
    The demand for automotive products is affected by a number of factors beyond
the Company's  control,  including  economic  conditions,  vehicle  quality  and
maintenance,  vehicle scrappage rates and weather conditions. Weather conditions
cause seasonal  variations  in the  Company's  results of  operations,  and  the
occurrence  of  extreme  weather  or  mild  weather  may  result  in significant
fluctuations in  such results.  Temperature extremes  tend to  enhance sales  by
causing  a higher  incidence of parts  failure and increasing  sales of seasonal
products, while milder weather  tends to depress sales.  In addition, in  recent
years  there have been,  and in the future  there are likely  to continue to be,
significant improvements in the  quality of new vehicles  and vehicle parts  and
extensions of manufacturers' warranties that may reduce demand for the Company's
products.  The Company  believes that  the unseasonably  mild weather conditions
that occurred  during the  winter of  1994-1995 throughout  most of  the  United
States  contributed,  together with  other factors,  to an  industry-wide market
softness, especially  with  respect  to  the  sale  of  seasonal  products,  and
adversely  affected the  Company's operating  results for  the first  quarter of
fiscal 1996.  The Company  continued to  experience, along  with other  industry
participants, a general softness in product demand through the fourth quarter of
fiscal  1996. See "Management's  Discussion and Analysis  of Financial Condition
and Results of Operations" in the Form 10-K and in the Form 10-Q, each of  which
is incorporated herein by reference.
    
 
MAJOR STOCKHOLDER
 
    Approximately  30% of the  outstanding Class A Common  Stock, par value $.01
per share (the "Class  A Common Stock"),  of Holding is owned  by The Clayton  &
Dubilier  Private Equity Fund IV Limited  Partnership ("Fund IV"), an investment
partnership managed by Clayton, Dubilier & Rice, Inc. ("CD&R"). Two of the  nine
current  members of the Board of Directors of the Company are employees of CD&R.
As a result, Fund IV is in a position to significantly influence the  management
and affairs of the Company.
 
FRAUDULENT CONVEYANCE CONSIDERATIONS
 
   
    In  connection  with  the  Acquisition,  APS,  Holding  and  each Restricted
Subsidiary  Guarantor   incurred   substantial   indebtedness,   including   the
indebtedness  under the Notes and  the New Credit Agreement  and the issuance of
the Note Guarantees. If, under relevant federal and state fraudulent  conveyance
statutes  in  a bankruptcy,  reorganization  or rehabilitation  case  or similar
proceeding or a lawsuit by or on  behalf of unpaid creditors of APS, Holding  or
any such Restricted Subsidiary Guarantor, a court were to find that, at the time
the  Notes  or  the  Note  Guarantees were  issued,  (i)  APS,  Holding  or such
Restricted Subsidiary Guarantor,  as the case  may be, issued  the Notes or  the
applicable  Note  Guarantee, as  the  case may  be,  with the  actual  intent of
hindering, delaying or defrauding current or  future creditors or (ii) (a)  APS,
Holding  or such Restricted  Subsidiary Guarantor, as the  case may be, received
less than  reasonably equivalent  value or  fair consideration  for issuing  the
Notes or the applicable Note Guarantee, as the case may be, and (b) APS, Holding
or  such Restricted Subsidiary Guarantor, as the  case may be, (1) was insolvent
or was  rendered insolvent  by reason  of the  Acquisition and/or  such  related
transactions,   including  the  incurrence  of  the  indebtedness  to  fund  the
Acquisition, (2) was engaged, or about  to engage, in a business or  transaction
for  which  its remaining  assets  constituted unreasonably  small  capital, (3)
intended to incur, or believed that it would incur, debts beyond its ability  to
pay  as such debts matured (as all of the foregoing or similar terms are defined
in or  interpreted under  such  fraudulent conveyance  statutes)  or (4)  was  a
defendant  in an action for  money damages, or had  a judgment for money damages
docketed against it (if, in either  case, after final judgment, the judgment  is
unsatisfied), such court could avoid or subordinate the Notes and the applicable
Note  Guarantee to presently existing and future indebtedness of APS, Holding or
such Restricted Subsidiary  Guarantor, as the  case may be  (in addition to  the
Senior Indebtedness to which the Notes are expressly subordinated and the Senior
Indebtedness to
    
 
                                       20
<PAGE>
which  the applicable Note  Guarantee is expressly  subordinated) and take other
action detrimental  to  the  holders  of the  Notes  and  the  Note  Guarantees,
including,  under  certain circumstances,  invalidating the  Notes and  the Note
Guarantees.
 
    The measure of insolvency for purposes of the foregoing considerations  will
vary  depending upon the federal or local law  that is being applied in any such
proceeding. Generally,  however,  APS,  Holding or  such  Restricted  Subsidiary
Guarantor,  as the case may be, would be considered insolvent if, at the time it
incurs the indebtedness constituting the Notes or the applicable Note  Guarantee
or  as a result of  the issuance of the Notes  or the applicable Note Guarantee,
either (i) the fair market value (or  fair saleable value or fair value) of  its
assets  (exclusive of any  property transferred with intent  to hinder, delay or
defraud) is less  than the amount  required to  pay the probable  amount of  its
total  existing debts and liabilities (including contingent liabilities) as they
become absolute and matured or (ii) it  is incurring debt beyond its ability  to
pay as such debt matures.
 
    The  Board of  Directors and  management of  each of  Holding, APS  and each
Restricted Subsidiary Guarantor believe that at the time of its issuance of  the
Notes  and the applicable Note  Guarantee, as the case  may be, APS, Holding and
each Restricted Subsidiary Guarantor (i) were (a) neither insolvent nor rendered
insolvent thereby,  (b) in  possession of  sufficient capital  to operate  their
respective   businesses  effectively  and  (c)   incurring  debts  within  their
respective abilities  to pay  as the  same mature  or become  due and  (ii)  had
sufficient  assets to  satisfy any probable  money judgment against  them in any
pending action. In  reaching the  foregoing conclusions, Holding,  APS and  each
Restricted Subsidiary Guarantor relied upon their analyses of internal cash flow
projections  and estimated values of their  assets and liabilities. There can be
no assurance, however, that  a court passing on  such questions would reach  the
same conclusions.
 
ABSENCE OF A PUBLIC MARKET FOR THE NOTES
 
   
    The  New  Notes are  being offered  to  the holders  of Existing  Notes. The
Existing Notes were  originally issued on  the Acquisition Closing  Date to  the
Initial  Purchasers pursuant to Section 4(2) of the Securities Act. The Existing
Notes subsequently have been  resold to (i)  qualified institutional buyers  (as
defined  in Rule 144A) in  reliance on, and subject  to the restrictions imposed
pursuant to,  Rule  144A, (ii)  institutional  investors that  were  "accredited
investors"  within the meaning of  subparagraph (a)(1), (2), (3)  or (7) of Rule
501 under the  Securities Act, and  (iii) certain non-U.S.  persons outside  the
United  States of  America in accordance  with Regulation S.  The Existing Notes
beneficially owned by qualified institutional buyers are eligible for trading in
the Private Offering, Resale and  Trading through Automated Linkages  ("PORTAL")
Market,  the National Association of  Securities Dealers' screen-based automated
market for trading of securities eligible for resale under Rule 144A.
    
 
    To the extent that Existing Notes are tendered and accepted in the  Exchange
Offer,  the  trading market  for the  remaining untendered  or tendered  but not
accepted Existing  Notes  could  be  adversely  affected.  The  New  Notes  will
constitute a new issue of securities, have no established trading market and may
not  be widely  distributed. Although the  Initial Purchasers  have informed the
Company that they currently intend to make  a market in the New Notes, they  are
not  obligated to do  so and may  discontinue market making  at any time without
notice. The Company does not intend to list the Notes on any national securities
exchange or to  seek the  admission thereof to  trading in  the Nasdaq  National
Market.  Accordingly,  there  can  be  no assurance  as  to  the  development or
liquidity of any market for either New Notes or the Existing Notes. If a  market
does develop, the Notes may trade at a discount from their principal amount, and
the  price of the Notes  may fluctuate depending on  many factors including, but
not limited to, prevailing interest  rates, the Company's operating results  and
the  market for similar securities, and liquidity may therefore be limited. If a
market for the Notes does not develop,  purchasers may be unable to resell  such
securities for an extended period of time, if at all.

                               THE EXCHANGE OFFER
 
PURPOSE
 
    In  connection  with the  initial sale  of the  Existing Notes,  APS agreed,
subject to certain conditions, to use  its best efforts to conduct the  Exchange
Offer.  APS's  purpose in  making  the Exchange  Offer  is to  comply  with such
agreement and to avoid the increase in  the interest rate borne by the  Existing
Notes  which  would  occur  if  the Exchange  Offer  were  not  duly  and timely
consummated. See "Registration Rights." The full terms of APS's obligations with
respect to the Exchange Offer are set forth in the Registration Agreement  which
has  been  filed as  an  exhibit to  the  Registration Statement  of  which this
Prospectus is a  part. The  Exchange Offer  should provide  holders of  Existing
Notes, which are subject to trading limitations, with the ability to effect, for
federal  income tax purposes, a tax-free exchange of such Existing Notes for New
Notes that should not be subject to such restrictions.
 
   
    Based on interpretations  by the staff  of the Commission,  as set forth  in
no-action  letters  issued  to  third parties,  the  Company  believes  that the
Exchange Offer will provide holders of  Existing Notes with New Notes that  will
generally  be freely transferable by holders  thereof (other than any holder who
is an "affiliate" of  APS within the  meaning of Rule  405 under the  Securities
Act),  who may  offer for  resale, resell or  otherwise transfer  such New Notes
without complying with  the registration and  prospectus delivery provisions  of
the  Securities Act, provided that  such New Notes are  acquired in the ordinary
course of each such holder's business and  such holders are not engaged in,  and
do  not  intend to  engage in,  a distribution  of  such New  Notes and  have no
arrangement or understanding with any person to participate in a distribution of
such New Notes. APS  has not sought,  and does not intend  to seek, a  no-action
letter from the Commission with respect to the effects of the Exchange Offer. By
tendering  Existing Notes  and executing the  Letter of  Transmittal, the holder
thereof shall represent and agree that (i) it is neither an affiliate of APS nor
a broker-dealer tendering Existing Notes acquired directly from APS for its  own
account,  (ii) it acquired the New Notes  in the ordinary course of its business
and (iii) it is not engaged in, and does not intend to engage in, a distribution
of the New Notes and it has no arrangement or understanding to participate in  a
distribution  of New  Notes. Holders  of Existing  Notes who  participate in the
Exchange  Offer  should  be   aware  that,  except  in   the  case  of   certain
broker-dealers  as described  below, if they  accept the Exchange  Offer for the
purpose of participating in a distribution of the New Notes, they cannot rely on
such interpretations by  the staff of  the Commission and  must comply with  the
registration and prospectus delivery requirements of the Securities Act.
    
 
    Each  broker-dealer that receives New Notes  for its own account in exchange
for  Existing  Notes,  where   such  Existing  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 with any  resale
of such New Notes. See "Plan of Distribution."
 
TERMS OF THE OFFER
 
    APS hereby offers, upon the terms and conditions set forth herein and in the
related Letter of Transmittal, to exchange New Notes for a like principal amount
of  outstanding Existing Notes. An aggregate of $100 million principal amount of
Existing Notes are outstanding. The Exchange  Offer is not conditioned upon  any
minimum principal amount of Existing Notes being tendered.
 
   
    The Exchange Offer will expire at 5:00 p.m., New York City time, on July 18,
1996  unless extended. The term "Expiration Date" means 5:00 p.m., New York City
time, on  July  18, 1996,  unless  APS, in  its  sole discretion,  notifies  the
Exchange Agent that the period of the Exchange Offer has been extended, in which
case  the term  "Expiration Date" means  the latest  time and date  on which the
Exchange Offer is so extended will expire. See "-- Expiration and Extension."
    
 
   
    Holders of Existing Notes who wish to exchange Existing Notes for New  Notes
and  who validly tender Existing  Notes to the Exchange  Agent or validly tender
Existing Notes by  complying with the  book-entry transfer procedures  described
below  and, in each  case, who furnish  the Letter of  Transmittal and any other
required documents to  the Exchange Agent,  at such holders'  option may  either
    
 
                                       22
<PAGE>
   
(i)  have certificated New  Notes mailed to  them by the  Exchange Agent or (ii)
hold a beneficial interest in one or  more New Global Certificates that will  be
deposited  with  the Depositary,  in  each case  promptly  after such  tender is
accepted by APS.  Subject to  the terms and  conditions of  the Exchange  Offer,
Existing  Notes which  have been validly  tendered prior to  the Expiration Date
will be  accepted on  or promptly  after  the Expiration  Date, subject  to  the
applicable  rules of the Commission. APS,  however, reserves the right, prior to
the first acceptance of tendered Existing Notes, to delay acceptance of tendered
Existing Notes, or to terminate the Exchange Offer, subject to the provisions of
Rule 14e-1(c)  under  the Securities  Exchange  Act  of 1934,  as  amended  (the
"Exchange  Act"), which  requires that  a tender  offeror pay  the consideration
offered or  return the  tendered securities  promptly after  the termination  or
withdrawal of a tender offer.
    
 
    In  addition, APS  reserves the  right to  waive any  condition or otherwise
amend the Exchange Offer prior to the acceptance of tendered Existing Notes.  If
any  amendment by APS  of the Exchange Offer  or waiver by  APS of any condition
thereto constitutes a material change in the information previously disclosed to
the holders of Existing Notes, APS will, in accordance with the applicable rules
of the Commission, promptly  disseminate disclosure of such  change in a  manner
reasonably  calculated to inform such holders of such change. If it is necessary
to permit  an  adequate dissemination  of  information regarding  such  material
change,  APS  will extend  the Exchange  Offer  to permit  an adequate  time for
holders of Existing Notes to consider the additional information.
 
CERTAIN EFFECTS OF THE EXCHANGE OFFER
 
    Because the Exchange Offer is for any and all Existing Notes, the number  of
Existing  Notes tendered  and exchanged  in the  Exchange Offer  will reduce the
principal amount of Existing  Notes outstanding. As a  result, the liquidity  of
any  remaining Existing Notes  may be substantially  reduced. The Existing Notes
beneficially owned by QIBs (as defined  herein) are currently eligible for  sale
pursuant  to Rule 144A through the PORTAL  System of the National Association of
Securities Dealers, Inc. Because APS  anticipates that most holders of  Existing
Notes  will  elect to  exchange such  Existing Notes  for New  Notes due  to the
absence of restrictions on the resale of New Notes under the Securities Act, APS
anticipates that the liquidity  of the market for  any Existing Notes  remaining
after the consummation of the Exchange Offer may be substantially limited.
 
   
    The  Existing Notes  that are  not exchanged for  New Notes  pursuant to the
Exchange Offer  will  remain restricted  securities  under the  Securities  Act.
Accordingly,  such Existing Notes may be resold  only (i) to APS , (ii) pursuant
to  a  registration  statement  that  has  been  declared  effective  under  the
Securities  Act, (iii) for so long as the Existing Notes are eligible for resale
pursuant to  Rule  144A, to  a  person it  reasonably  believes is  a  qualified
institutional  buyer (as defined in Rule 144A and referred to in this Prospectus
as a  "Qualified Institutional  Buyer"  or "QIB")  that  purchases for  its  own
account  or for the account of a Qualified Institutional Buyer to whom notice is
given that the transfer is being made in reliance on Rule 144A, (iv) pursuant to
offers and sales to non-U.S. persons that occur outside the United States within
the meaning of Regulation S, (v)  to an institutional "accredited investor"  (as
defined  in Rule 501(a)(1), (2), (3) or (7) of Regulation D under the Securities
Act  and  referred  to  in  this  Prospectus  as  an  "Institutional  Accredited
Investor") that is acquiring the security for its own account or for the account
of  such an  Institutional Accredited Investor  for investment  purposes and not
with a view to,  or for offer  or sale in connection  with, any distribution  in
violation  of  the  Securities  Act  or (vi)  pursuant  to  any  other available
exemption from the registration requirements  of the Securities Act, subject  in
each  of the foregoing cases (a) to  any requirement of law that the disposition
of its property or the property of  such investor account or accounts be at  all
times  within its  or their  control and (b)  to compliance  with any applicable
state or other securities laws. After  the Exchange Offer is completed,  holders
of   Existing  Notes  will  not  have  certain  registration  rights  under  the
Registration Agreement. See "-- Termination of Certain Rights."
    
 
EXPIRATION AND EXTENSION
 
   
    The Exchange Offer will expire at 5:00 p.m., New York City time, on July 18,
1996, unless extended  by APS. The  Exchange Offer  may be extended  by oral  or
written notice from APS to the
    
 
                                       23
<PAGE>
Exchange  Agent at any time or  from time to time, on  or prior to the date then
fixed for the expiration of the Exchange Offer. Notwithstanding any extension of
the Exchange Offer, if the Exchange Offer  is not consummated by July 23,  1996,
Special  Interest (as  defined herein)  will accrue.  See "Registration Rights."
Public announcement of any extension of  the Exchange Offer will be timely  made
by  APS, but, unless otherwise required by  law or regulation, APS will not have
any obligation to communicate  such public announcement other  than by making  a
release to the Dow Jones News Service.
 
ACCRUED INTEREST
 
    Holders  of Existing Notes  that are accepted for  exchange will not receive
any accrued interest thereon. However, each New Note will bear interest from the
most recent date on which interest  has been paid on the corresponding  Existing
Note, or, if no interest has been paid, from January 25, 1996.
 
CONDITIONS
 
    Notwithstanding any other provisions of the Exchange Offer, or any extension
of  the Exchange Offer,  APS will not be  required to cause  the issuance of New
Notes in respect of any validly tendered Existing Notes not accepted and,  prior
to  the acceptance of tendered Existing  Notes, may terminate the Exchange Offer
(by oral  or  written  notice  to  the  Exchange  Agent  and  by  timely  public
announcement  communicated,  unless  otherwise  required  by  applicable  law or
regulation, by making a release  to the Dow Jones  News Service) or, subject  to
compliance  with the applicable rules of the Commission, delay the acceptance of
the tendered Existing Notes,  if any material change  occurs which is likely  to
affect the Exchange Offer, including, but not limited to, the following:
 
   
        (i)  there  shall  occur  (a)  any  general  suspension  of  or  general
    limitation on  prices  for,  or  trading  in,  securities  on  any  national
    securities exchange or in the over-the-counter market, (b) any limitation by
    any  governmental agency or authority which may adversely affect the ability
    of the Company  to complete  the transactions contemplated  by the  Exchange
    Offer,  (c)  a declaration  of  a banking  moratorium  or any  suspension of
    payments in respect of banks in the  United States or any limitation by  any
    governmental  agency or authority  which adversely affects  the extension of
    credit or (d) a  commencement of a war,  armed hostilities or other  similar
    international  calamity directly or indirectly  involving the United States,
    or, in  the case  of  any of  the  foregoing existing  at  the time  of  the
    commencement  of the  Exchange Offer,  a material  acceleration or worsening
    thereof;
    
 
   
        (ii) any  statute,  rule  or  regulation shall  have  been  proposed  or
    enacted,  or any action shall have been taken or proposed to be taken by any
    governmental authority which, in the sole judgment of the Company, would  or
    might prohibit, restrict or delay completion of the Exchange Offer;
    
 
   
       (iii)  there shall be  instituted or threatened  any action or proceeding
    before any court or  governmental agency challenging  the Exchange Offer  or
    otherwise directly or indirectly relating to the Exchange Offer;
    
 
   
       (iv)  there  shall  occur  any  development  in  any  pending  action  or
    proceeding which,  in the  sole  judgment of  the  Company, would  or  might
    prohibit, restrict or delay consummation of the Exchange Offer;
    
 
   
        (v)  there exists, in  the sole judgment  of the Company,  any actual or
    threatened legal  impediment (including  a  default or  prospective  default
    under an agreement, indenture or other instrument or obligation to which the
    Company  is  a party  or by  which it  is  bound) to  the completion  of the
    Exchange Offer; or
    
 
   
       (vi)  prior  to  the  completion  of  the  Exchange  Offer,  the  Company
    determines  there  has been  a change  in  law or  applicable interpretation
    thereof by the staff of the Commission such that the New Notes that would be
    received by holders  in the Exchange  Offer in exchange  for Existing  Notes
    would  not be transferable, upon receipt, by  each such holder (other than a
    holder that is  an affiliate of  APS, a  holder who acquires  the New  Notes
    outside the ordinary course of such holder's
    
 
                                       24
<PAGE>
   
    business,  a holder who is engaged in or intends to engage in a distribution
    of such New Notes  or a holder who  has arrangements or understandings  with
    any  person  to  participate  in  the  Exchange  Offer  for  the  purpose of
    distributing the New Notes) without restriction under the Securities Act.
    
 
   
    Subject to the obligations under the Registration Agreement to use its  best
efforts  to  complete the  Exchange Offer,  the  Company expressly  reserves the
right, at  any time  prior to  the  acceptance of  tendered Existing  Notes,  to
terminate the Exchange Offer and not accept for exchange any Existing Notes upon
the  occurrence of any of  the foregoing conditions. In  addition, APS may amend
the Exchange Offer  at any  time prior to  the acceptance  of tendered  Existing
Notes  if any of the  conditions set forth above  occur. Moreover, regardless of
whether any of the foregoing conditions has occurred, APS reserves the right, in
its reasonable discretion, to  amend the Exchange Offer  in any manner prior  to
the  acceptance of tendered Existing Notes, although it has no current intention
to do so.
    
 
    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 sole discretion. Any determination made by the Company
concerning an event, development or circumstance described or referred to  above
will be final and binding on all parties to the Exchange Offer.
 
    In  addition, the  Company will not  accept for exchange  any Existing Notes
tendered, and no  New Notes will  be issued  in exchange for  any such  Existing
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.
 
   
    If the event referred to  in clause (vi), above,  shall occur, APS shall  be
under  no continuing obligation under the Registration Agreement to complete the
Exchange Offer, but in lieu thereof will  be obligated to file and use its  best
efforts  to secure and maintain the effectiveness  under the Securities Act of a
"shelf" registration statement providing for  the resale of Existing Notes.  See
"Registration Rights."
    
 
HOW TO TENDER
 
   
    A  holder  of  Existing Notes  may  tender  Existing Notes  by  (i) properly
completing and signing  the Letter of  Transmittal or a  facsimile thereof  (all
references  in this Prospectus to  the Letter of Transmittal  shall be deemed to
include a facsimile  thereof), having their  signatures guaranteed if  required,
and  delivering the same, together with the  Existing Notes being tendered (or a
confirmation of an appropriate book-entry transfer), to the Exchange Agent on or
prior to the Expiration Date, or  (ii) requesting a broker, dealer, bank,  trust
company  or other nominee to effect the transaction for such holder prior to the
Expiration Date.
    
 
    New Notes will not be issued  in the name of a  person other than that of  a
registered holder of the Existing Notes appearing on the note register.
 
    The  Exchange Agent will  establish an account with  respect to the Existing
Notes at DTC for purposes of the Exchange Offer promptly after the date of  this
Prospectus, and any financial institution which is a participant in DTC may make
book-entry  delivery  of the  Existing  Notes by  causing  DTC to  transfer such
Existing Notes  into  the Exchange  Agent's  account in  accordance  with  DTC's
procedure for such transfer. Although delivery of Existing Notes may be effected
through book-entry transfer into the Exchange Agent's account at DTC, the Letter
of  Transmittal, with any  required signature guarantees  and any other required
documents, must in any case be transmitted to and received by the Exchange Agent
on or prior  to the Expiration  Date at the  address set forth  below under  "--
Exchange  Agent," or the  guaranteed delivery procedure  described below must be
complied with. Delivery of documents to DTC does not constitute delivery to  the
Exchange Agent. See "-- Exchanging Book-Entry Notes."
 
                                       25
<PAGE>
    THE  METHOD OF DELIVERY OF EXISTING NOTES AND ALL OTHER DOCUMENTS, INCLUDING
DELIVERY THROUGH DTC,  IS AT THE  ELECTION AND RISK  OF THE HOLDER.  IF SENT  BY
MAIL, IT IS RECOMMENDED THAT REGISTERED MAIL, RETURN RECEIPT REQUESTED, BE USED,
AND PROPER INSURANCE BE OBTAINED.
 
    If  a holder desires to tender Existing Notes pursuant to the Exchange Offer
and such holder's Existing Notes are not immediately available or time will  not
permit  all of  the above  documents to  reach the  Exchange Agent  prior to the
Expiration Date,  or such  holder cannot  complete the  procedure of  book-entry
transfer  on  a timely  basis,  such tender  may  be effected  if  the following
conditions are satisfied:
 
   
        (i)  such  tenders  are  made  by  or  through  an  eligible   guarantor
    institution  which is a  member of one of  the following Signature Guarantee
    Programs: The Securities Transfer Agents Medallion Program (STAMP); The  New
    York  Stock  Exchanges  Medallion  Signature  Program  (MSP)  and  The Stock
    Exchanges Medallion Program (SEMP) (each, an "Eligible Institution");
    
 
   
        (ii) a  properly  completed  and  duly  executed  notice  of  guaranteed
    delivery  ("Notice  of  Guaranteed  Delivery"),  in  substantially  the form
    provided by the Company, is received by the Exchange Agent as provided below
    on or prior to the Expiration Date; and
    
 
   
       (iii) the Existing Notes, in proper form for transfer (or confirmation of
    book-entry transfer of such Existing Notes into the Exchange Agent's account
    at DTC as  described above),  together with  a properly  completed and  duly
    executed  Letter  of Transmittal  and all  other  documents required  by the
    Letter of Transmittal, are  received by the Exchange  Agent within five  New
    York  Stock Exchange, Inc. trading days after  the date of execution of such
    Notice of Guaranteed Delivery.
    
 
    The Notice of Guaranteed Delivery may be delivered by hand or transmitted by
facsimile transmission  or  mail  to  the Exchange  Agent  and  must  include  a
guarantee  by an Eligible  Institution in the  form set forth  in such Notice of
Guaranteed Delivery.
 
    A tender  will be  deemed to  have been  received as  of the  date when  the
tendering  holder's duly  signed Letter  of Transmittal  accompanied by Existing
Notes (or a timely  confirmation received of a  book-entry transfer of  Existing
Notes  into  the Exchange  Agent's account  at  DTC) or  a Notice  of Guaranteed
Delivery from  an  Eligible  Institution  is received  by  the  Exchange  Agent.
Issuances  of New Notes  in exchange for  Existing Notes tendered  pursuant to a
Notice of  Guaranteed Delivery  by an  Eligible Institution  will be  made  only
against delivery of the Letter of Transmittal (and any other required documents)
and  the tendered Existing Notes  (or a timely confirmation  received of a book-
entry transfer of Existing  Notes into the Exchange  Agent's account at DTC)  to
the Exchange Agent or confirmation of the Book-Entry Transfer Facility Automated
Tender  Offer Program  ("ATOP") procedures set  forth below.  See "-- Exchanging
Book-Entry Notes."
 
    Partial tenders of  Existing Notes  may be made  only if  (i) the  principal
amount  tendered is equal to $1,000 or an integral multiple thereof and (ii) the
remaining untendered portion of such Existing Notes is in a principal amount  of
$250,000,  or any integral multiple of $1,000  in excess of such amount. Holders
tendering less than the entire principal  amount of any Existing Note they  hold
in  accordance with the foregoing  restrictions must appropriately indicate such
fact on the Letter of Transmittal accompanying the tendered Existing Note.
 
    With respect to tenders of Existing  Notes, APS reserves full discretion  to
determine  whether the documentation is complete  and generally to determine all
questions as  to  tenders,  including the  date  of  receipt of  a  tender,  the
propriety  of  execution of  any document,  and  any other  questions as  to the
validity, form, eligibility  or acceptability  of any tender.  APS reserves  the
right  to reject  any tender not  in proper form  or otherwise not  valid or the
acceptance of  exchange  of which,  in  the opinion  of  APS's counsel,  may  be
unlawful  or to waive any irregularities or conditions, and APS's interpretation
of the terms and conditions of the Exchange Offer (including the instructions on
the Letter of Transmittal)  will be final.  APS shall not  be obligated to  give
notice  of any  defects or  irregularities in  tenders and  shall not  incur any
liability for failure to give any such notice. The Exchange Agent may, but shall
not be obligated to,  give notice of any  irregularities or defects in  tenders,
and shall not incur any liability
 
                                       26
<PAGE>
for  any failure to give any such notice.  Existing Notes shall not be deemed to
have  been  duly  or  validly  tendered   unless  and  until  all  defects   and
irregularities  have  been cured  or  waived. All  improperly  tendered Existing
Notes, as well as Existing Notes in excess of the principal amount tendered  for
exchange,  will be returned (unless irregularities  and defects are timely cured
or waived), without cost to  the tendering holder (or,  in the case of  Existing
Notes  delivered  by book-entry  transfer within  DTC, will  be credited  to the
account maintained within  DTC by the  participant in DTC  which delivered  such
shares), promptly after the Expiration Date.
 
    If the Letter of Transmittal is signed by a person or persons other than the
registered  holder or  holders of  Existing Notes,  such Existing  Notes must be
endorsed or accompanied by appropriate powers of attorney, in either case signed
exactly as the name or names of the registered holder or holders that appear  on
the Existing Notes.
 
    If the Letter of Transmittal or any Existing Notes or powers of attorney 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.
 
EXCHANGING BOOK-ENTRY NOTES
 
    The  Exchange Agent  and DTC have  confirmed that  any financial institution
that is a participant in DTC may utilize ATOP to tender Existing Notes.
 
    Any DTC  participant  may make  book-entry  delivery of  Existing  Notes  by
causing DTC to transfer such Existing Notes into the Exchange Agent's account in
accordance  with DTC's ATOP  procedures for transfer.  However, the exchange for
the Existing Notes so  tendered will only be  made after timely confirmation  (a
"Book-Entry  Confirmation") of such  book-entry transfer of  Existing Notes into
the Exchange Agent's  account, and timely  receipt by the  Exchange Agent of  an
Agent's  Message (as such  term is defined  in the next  sentence) and any other
documents required  by the  Letter of  Transmittal. The  term "Agent's  Message"
means  a message,  transmitted by  DTC and  received by  the Exchange  Agent and
forming part of a Book-Entry Confirmation, which states that DTC has received an
express acknowledgment from a participant tendering Existing Notes that are  the
subject  of such Book-Entry Confirmation that  such participant has received and
agrees to be  bound by  the terms  of the Letter  of Transmittal,  and that  the
Company may enforce such agreement against such participant.
 
TERMS AND CONDITIONS OF THE LETTER OF TRANSMITTAL
 
    The  Letter of Transmittal  contains, among other  things, certain terms and
conditions which are summarized below and are part of the Exchange Offer.
 
   
    Each holder who tenders Existing  Notes (other than certain  broker-dealers)
and  executes the Letter of Transmittal will  be required to represent and agree
that such tendering holder  is neither an affiliate  of APS nor a  broker-dealer
tendering  Existing Notes  acquired directly from  APS for its  own account, has
acquired the New Notes in  the ordinary course of  its business, is not  engaged
in,  and does not intend to engage in, the distribution of the 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
Existing Notes, where such Existing Notes were acquired by such broker-dealer as
a  result  of  market-making  activities  or  other  trading  activities,   must
acknowledge, among other things, that it will deliver a 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 a prospectus,  a
broker-dealer will not be deemed to admit that it is an "underwriter" within the
meaning of the Securities Act.
    
 
   
    Existing  Notes tendered in exchange for New Notes (or a timely confirmation
of a  book-entry transfer  of  such Existing  Notes  into the  Exchange  Agent's
account  at DTC)  must be  received by  the Exchange  Agent, with  the Letter of
Transmittal and any other required documents, by 5:00 p.m., New York City  time,
on  or prior to July  18, 1996, unless extended, or  within the time periods set
forth above
    
 
                                       27
<PAGE>
in "--  How to  Tender" pursuant  to a  Notice of  Guaranteed Delivery  from  an
Eligible  Institution. The party tendering the  Existing Notes for exchange (the
"Holder") shall be deemed  to have sold, assigned  and transferred the  Existing
Notes  to the Exchange Agent,  as agent of APS,  and irrevocably constituted and
appointed the Exchange Agent as the Holder's agent and attorney-in-fact to cause
the Existing  Notes to  be  transferred and  exchanged.  The Holder  shall  also
warrant  that it has full power and authority to tender, exchange, sell, assign,
and transfer the Existing Notes and to  acquire the New Notes issuable upon  the
exchange  of such tendered Existing Notes, that  the Exchange Agent, as agent of
APS, will acquire good  and unencumbered title to  the tendered Existing  Notes,
free  and clear of  all liens, restrictions, charges  and encumbrances, and that
the Existing Notes tendered for exchange  are not subject to any adverse  claims
when  accepted by  the Exchange Agent,  as agent  of APS. The  Holder shall also
warrant that it will, upon request, execute and deliver any additional documents
deemed by APS or the Exchange Agent to be necessary or desirable to complete the
exchange, sale, assignment  and transfer  of the Existing  Notes. All  authority
conferred  or agreed to be conferred in  the Letter of Transmittal by the Holder
will survive the death  or incapacity of  the Holder and  any obligation of  the
Holder  shall  be binding  upon the  heirs, executors,  administrators, personal
representatives, trustees in bankruptcy,  legal representatives, successors  and
assigns of such Holder.
 
    Signature(s)  on the Letter of Transmittal will be required to be guaranteed
as set forth  above in "--  How to Tender."  All questions as  to the  validity,
form,  eligibility (including time  of receipt) and  acceptability of any tender
will be determined by APS, in  its sole discretion, and such determination  will
be  final and binding. Unless waived by  APS, irregularities and defects must be
cured by the Expiration Date.
 
WITHDRAWAL RIGHTS
 
    All tenders of  Existing Notes may  be withdrawn  at any time  prior to  the
Expiration Date. To be effective, a notice of withdrawal must be timely received
by  the Exchange Agent at the address set forth below under "-- Exchange Agent."
Any notice  of  withdrawal  must specify  the  person  named in  the  Letter  of
Transmittal  as  having tendered  the  Existing Notes  to  be withdrawn.  If the
Existing Notes  have  been  physically  delivered to  the  Exchange  Agent,  the
tendering  holder must  also submit  the serial  number shown  on the particular
Existing Notes  to be  withdrawn.  If the  Existing  Notes have  been  delivered
pursuant  to the book-entry procedures set forth above under "-- How to Tender,"
any notice of withdrawal must specify  the name and number of the  participant's
account  at DTC to be  credited with the withdrawn  Existing Notes. The Exchange
Agent will return the properly withdrawn  Existing Notes as soon as  practicable
following receipt of the notice of withdrawal. All questions as to the validity,
including time of receipt, of notices and withdrawals will be determined by APS,
and such determination will be final and binding on all parties.
 
ACCEPTANCE OF TENDERS
 
   
    Subject  to the  terms and conditions  of the Exchange  Offer, including the
reservation of certain rights by APS, Existing Notes tendered (either physically
or through  book-entry delivery  as described  in  "-- How  to Tender")  with  a
properly  executed Letter of  Transmittal and all  other required documentation,
and not withdrawn, will be accepted on or promptly after the Expiration Date. At
the option of the holder of a New Note, such New Note may be held in the form of
either (i) a certificated New Note or (ii) a beneficial interest in one or  more
of  the  New  Global  Certificates.  Beneficial  interests  in  the  New  Global
Certificates will  be shown  on, and  transfers thereof  will be  effected  only
through,  records maintained by  DTC and its participants.  Subject to the terms
and conditions of  the Exchange Offer,  certificated New Notes  to be issued  in
exchange  for properly  tendered Existing Notes  will be mailed  by the Exchange
Agent promptly after the acceptance of such tendered Existing Notes and the  New
Notes to be issued in the form of New Global Certificates will be deposited with
DTC promptly after acceptance of the related tendered Existing Notes. Acceptance
of  tendered Existing Notes will be effected by the delivery of a notice to that
effect by APS  to the Exchange  Agent. Subject  to the applicable  rules of  the
Commission,  APS,  however,  reserves  the right,  prior  to  the  acceptance of
tendered Existing Notes, to delay acceptance of tendered Existing Notes upon the
occurrence of  any of  the conditions  set  forth above  under the  caption  "--
Conditions." APS confirms that its reservation of
    
 
                                       28
<PAGE>
the  right to  delay acceptance  of tendered  Existing Notes  is subject  to the
provisions of Rule 14e-1(c) under the Exchange Act which requires that a  tender
offeror pay the consideration offered or return the tendered securities promptly
after the termination or withdrawal of a tender offer.
 
    Although APS does not currently intend to do so, if it modifies the terms of
the  Exchange Offer,  such modified  terms will be  available to  all holders of
Existing Notes, whether or not their Existing Notes have been tendered prior  to
such  modification. Any  material modification  will be  disclosed in accordance
with the applicable rules of the Commission and, if required, the Exchange Offer
will be extended to permit holders  of Existing Notes adequate time to  consider
such modification.
 
    The tender of Existing Notes pursuant to any one of the procedures set forth
in  "-- How to Tender" will constitute an agreement between the tendering holder
and APS upon the terms and subject to the conditions of the Exchange Offer.

    The Bank of  New York  has agreed to  provide certain  services as  Exchange

    Delivery to other than the above address will not constitute valid delivery.
 
SOLICITATION OF TENDERS; EXPENSES
 
    Except  as described above  under "-- Exchange Agent,"  APS has not retained
any agent in connection with the Exchange  Offer and will not make any  payments
to  brokers, dealers or other persons for soliciting or recommending acceptances
of the Exchange Offer. APS, will, however, reimburse the Exchange Agent for  its
reasonable  out-of-pocket expenses  in connection  therewith. APS  will also pay
brokerage houses and other custodians,  nominees and fiduciaries the  reasonable
out-of-pocket  expenses incurred by them in forwarding copies of this Prospectus
and related documents  to the  beneficial owners of  the Existing  Notes and  in
handling or forwarding tenders for their customers.
 
TRANSFER TAXES
 
    APS  will pay  all transfer  taxes, if  any, applicable  to the  transfer of
Existing Notes to it or its order  pursuant to the Exchange Offer. If,  however,
New Notes and/or substitute Existing Notes not exchanged are to be delivered to,
or  are to be  registered or issued  in the name  of, any person  other than the
registered holder of the Existing Notes tendered, or if tendered Existing  Notes
are  registered in  the name  of any  person other  than the  person signing the
Letter of Transmittal, or if a transfer tax is imposed for any reason other than
the transfer of  Existing Notes  to the  Company or  its order  pursuant to  the
Exchange  Offer, the amount of  any such transfer taxes  (whether imposed on the
registered holder or any other person) will be payable by the tendering  holder.
If  satisfactory evidence of payment of such taxes or exemption therefrom is not
submitted with the Letter of Transmittal, the amount of such transfer taxes will
be billed directly to such tendering holder.
 
                                       29
<PAGE>
ACCOUNTING TREATMENT
 
    The carrying value of the Existing Notes is expected to become the  carrying
value  of the New Notes at the time  of the Exchange Offer. Accordingly, no gain
or loss for accounting purposes will be recognized. The expenses of the Exchange
Offer will be amortized over the term of the New Notes.
 
TERMINATION OF CERTAIN RIGHTS
 
   
    Holders of the  New Notes  will not be  entitled to  certain special  rights
under  the Registration Agreement, which rights will terminate when the Exchange
Offer is completed. Pursuant to  the Registration Agreement, the Exchange  Offer
shall  be deemed  to be "completed"  upon the  occurrence of (i)  the filing and
effectiveness under the Securities Act  of a registration statement relating  to
the  New Notes to be issued in the  Exchange Offer, (ii) the maintenance of such
registration statement continuously effective for a  period of not less than  30
days  after notice  has been  sent to  holders of  Existing Notes  and (iii) the
delivery by APS in exchange for all Existing Notes that have been duly  tendered
and  not  validly withdrawn  on or  prior to  the Expiration  Date of  New Notes
transferable by each holder thereof (other than a holder that is an affiliate of
APS within the  meaning of Rule  405 under the  Securities Act, a  broker-dealer
tendering  Existing  Notes acquired  directly from  APS for  its own  account, a
holder who acquires the New Notes  outside the ordinary course of such  holder's
business  or  a  holder  who  is  engaged in  or  who  intends  to  engage  in a
distribution of the New Notes or who has arrangements or understandings with any
person to participate in the Exchange Offer for the purpose of distributing  the
New  Notes) without restrictions under the  Securities Act. The rights that will
terminate include  the  right  to require  the  Company  (i) to  file  with  the
Commission,  and use  its best  efforts to cause  to become  effective under the
Securities Act, a registration statement with respect to the New Notes and  (ii)
other  than in certain  limited circumstances, to file  with the Commission, use
its best efforts to cause to become effective under the Securities Act and  keep
continuously  effective for a period of up to three years a "shelf" registration
statement providing for  the registration of,  and the sale  on a continuous  or
delayed basis by the holders of, Existing Notes.
    
 
                                USE OF PROCEEDS
 
   
    The Exchange Offer is intended to satisfy certain of APS's obligations under
the  Registration Agreement.  APS will  not receive  any cash  proceeds from the
issuance of the New Notes offered  hereby. In consideration for issuing the  New
Notes  as contemplated in this Prospectus, APS will receive in exchange Existing
Notes in like principal amount, the form and terms of which are identical in all
material respects to the form  and terms of the  New Notes, except as  otherwise
described  herein. The Existing Notes surrendered  in exchange for the New Notes
will be retired and  canceled and cannot be  reissued. Accordingly, issuance  of
the New Notes will not result in any increase in the indebtedness of APS.
    
 
   
    The  proceeds to APS for  the sale of the  Existing Notes were approximately
$96.25 million,  net  of  Initial  Purchasers' discount  and  certain  fees  and
expenses relating to the offering of the Existing Notes. Such proceeds were used
to  pay  the closing  cash purchase  price for  the Acquisition  of PI  of $79.7
million (which was subsequently adjusted to  $74.9 million), to repay a  portion
of  the borrowings then outstanding under the  Prior Credit Agreement and to pay
fees and expenses incurred in connection with the Acquisition.

             SELECTED HISTORICAL CONSOLIDATED FINANCIAL INFORMATION
                           OF APS HOLDING CORPORATION
 
   
    The  following table sets forth  historical financial information of Holding
as of and for the five years  ended January 27, 1996, January 28, 1995,  January
29,  1994, January 30,  1993 and January  25, 1992 and  as of and  for the three
months ended  April  25, 1996  and  1995. The  balance  sheet and  statement  of
operations  information as of and  for the fiscal years  ended January 27, 1996,
January 28, 1995, January 29, 1994, January  30, 1993 and January 25, 1992  have
been  derived  from audited  consolidated financial  statements of  Holding. The
balance sheet and statement  of operations information as  of and for the  three
months ended April 25, 1996 and 1995 were derived fom the unaudited consolidated
financial  statements of Holding, which include all adjustments which management
considers necessary for a fair presentation of the information for such periods,
all of which were of  a normal recurring nature.  The results of operations  for
the  three-month periods  are not  necessarily indicative  of the  results to be
expected for  the  full year.  The  table should  be  read in  conjunction  with
"Management's  Discussion  and Analysis  of Financial  Condition and  Results of
Operations" and the  Consolidated Financial  Statements of  Holding and  related
notes  and the other financial information included  in the Form 10-K and in the

(1) Operating income for fiscal  1996 reflects the impact  of an $11,224  pretax
    charge  related  to  a facility  rationalization  and  restructuring program
    undertaken in conjunction with the Acquisition, the adoption of SFAS No. 121
    relating to  the  impairment and  disposal  of long-lived  assets,  and  the
    write-down of certain assets.
 
(2) Other  income  in  fiscal  1993 includes  a  non-recurring  gain  on pension
    curtailment of $3,288.
 
(3) The benefit for income taxes in fiscal 1995 includes a non-recurring benefit
    of $14,802, recognized as a result  of the Company's ability to utilize  its
    net operating loss carryforwards.
 
(4) Excluding  the $11,224 asset impairment and restructuring charge recorded by
    the Company in the fourth quarter of fiscal 1996, the Company would have had
    EBITDA of  $49,957  for the  fiscal  year  ended January  27,  1996.  EBITDA
    represents  the sum of income before interest expense and income taxes, plus
    depreciation  and  amortization.  EBITDA  should  not  be  construed  as   a
    substitute  for  income  from  operations,  net  income  or  cash  flow from
    operating activities, for the purpose  of analyzing the Company's  operating
    performance,  financial position and  cash flows. The  Company has presented
    EBITDA because  it is  commonly used  by investors  to analyze  and  compare
    companies on the basis of operating performance and to determine a company's
    ability to service debt.
 
(5) For  purposes of computing the ratio  of earnings to fixed charges, earnings
    consist of income from continuing  operations before income taxes and  fixed
    charges. Fixed charges include interest expense and the portion of operating
    rents which is deemed representative of an interest factor.

              PRO FORMA COMBINED CONDENSED STATEMENT OF OPERATIONS
                             (DOLLARS IN THOUSANDS)
 
    The  unaudited  pro  forma  combined condensed  statement  of  operations of
Holding for the fiscal year ended January 27, 1996 (the "Pro Forma Statement  of
Operations")  has  been  prepared  to illustrate  the  estimated  effect  of the
Acquisition and related  transactions, including  the issuance  of the  Existing
Notes and borrowings under the New Credit Agreement, described elsewhere in this
Prospectus  and  in  the  accompanying  notes  to  the  Pro  Forma  Statement of
Operations. The  Pro  Forma Statement  of  Operations  does not  purport  to  be
indicative  of the results of operations or financial position of Holding and PI
that would have actually been obtained  had such transactions been completed  as
of  the assumed date and  for the period presented, or  which may be obtained in
the future.
 
   
    The Pro  Forma  Statement  of  Operations gives  pro  forma  effect  to  the
Acquisition  and related  transactions, including  the issuance  of the Existing
Notes and borrowings under the New Credit Agreement, as if they had occurred  on
January 29, 1995, and includes the following as if they were realized during the
applicable  period:  (i)  reductions  in  cost  of  goods  sold  resulting  from
purchasing economies to  be extended to  the Company by  its existing  suppliers
based  on  arrangements the  Company has  negotiated  with such  suppliers; (ii)
reductions in selling, general and  administrative expenses through the  closure
(as  of  the date  of this  Prospectus)  of four  of the  Company's distribution
centers (including two PI distribution  centers) and the anticipated closure  of
seven  additional PI distribution centers, and consolidation of these operations
into the combined companies' remaining  facilities, as well as consolidation  of
certain  administrative  functions; (iii)  net increase  in interest  expense to
reflect the issuance of the Existing  Notes and borrowings under the New  Credit
Agreement;  and  (iv)  adjustments  to  conform  PI's  accounting  policies  and
practices to those of  the Company with respect  to inventory and  depreciation.
The  Company believes that it  can complete the steps  required to fully realize
the benefits reflected in the pro  forma adjustments to the Pro Forma  Statement
of   Operations  within  one  year   following  the  Acquisition,  with  partial
realization of such benefits prior to that time. However, unanticipated  factors
may  delay the realization of such benefits, and there can be no assurances that
such benefits will be realized.
    
 
    The Pro  Forma  Statement  of  Operations has  been  prepared  assuming  the
retention  of all  of the  Company's and  PI's sales  following the Acquisition.
Management anticipates, however,  that it  will retain  significantly less  than
100% of PI's sales as a result of the loss of certain associated jobbers and the
closure  of  certain Company-owned  stores. The  lower  retention of  sales will
result in lower operating results of  the combined companies than are  reflected
in  the Pro Forma Statement of Operations. See Note 1 to the Pro Forma Statement
of Operations.
 
   
    The Pro Forma Statement of Operations should be read in conjunction with the
audited Consolidated Financial Statements of  Holding for the fiscal year  ended
January  27, 1996, including the notes thereto, and "Management's Discussion and
Analysis of Financial Condition and Results of Operations" in the Form 10-K  and
in  the Form  10-Q, each  of which  is incorporated  herein by  reference, "Risk
Factors" and the audited  Financial Statements of PI  for the fiscal year  ended
December  31, 1995, including the notes thereto,  set forth on pages F-1 through
F-10.

                             (DOLLARS IN THOUSANDS)
 
    (1)  The Pro Forma Statement of  Operations assumes that the Acquisition and
related  transactions,  including  the  issuance  of  the  Existing  Notes   and
borrowings  under the  New Credit Agreement,  occurred on January  29, 1995. For
purposes of the Pro Forma Statement of Operations, PI's historical statement  of
operations  for the fiscal  year ended December  31, 1995 was  combined with the
Company's historical statement of operations  for the fiscal year ended  January
27, 1996.
 
    The  Pro Forma Statement of Operations  has been prepared assuming retention
of all of  the Company's and  PI's sales following  the Acquisition.  Management
anticipates,  however, that it will retain  significantly less than 100% of PI's
sales. The lower retention of sales  will result in lower operating income,  net
income,  cost of  goods sold, selling,  general and  administrative expenses and
provision for income  taxes than  are reflected in  the Pro  Forma Statement  of
Operations.
 
    (2) Cost of goods sold adjustments include the following:

    Management  believes that approximately half  of the total annual purchasing
    savings of $6,278 resulting from these purchasing economies will be realized
    in the first year following the Acquisition, and, accordingly, 50% of  these
    purchasing  savings have been reflected in the fiscal year ended January 27,

        (a)  The Company  (as of  the date of  this Prospectus)  has closed four
    distribution  centers  (including  two  PI  distribution  centers),  and  is
    committed   to  closing   seven  additional  PI   distribution  centers  and
    consolidating sales from  all of  the closed distribution  centers into  the
    remaining  facilities of  the combined  group. In  addition, the  Company is
    committed to consolidating certain administrative functions. For purposes of
    the Pro Forma Statement of  Operations, adjustments relating to the  closure
    of  the PI distribution  centers are reflected  on a phased-in  basis in the
    fiscal year ended January 27, 1996.  Adjustments relating to the closure  of
    the  two Company distribution  centers are not reflected  in the fiscal year
    ended January 27, 1996. The Company expects to

                             (DOLLARS IN THOUSANDS)
   
    realize significant cost  savings related to  headcount reductions from  the
    closure  of  these  distribution  centers offset,  in  part,  by incremental
    personnel requirements necessary to support  the operations of the  combined
    businesses.  The number of incremental  distribution center personnel needed
    was calculated  (i) assuming  retention  of 100%  of PI's  historical  sales
    volume  and number  of customers; (ii)  using actual  productivity levels at
    each respective distribution center expected to receive the additional sales
    and customers;  and (iii)  assumes the  incremental employees  are added  in
    accordance with the timing of the existing consolidation plan. The number of
    incremental  administrative employees was determined on a departmental basis
    by management of the Company who identified the number of individuals needed
    to effectively handle the increased workload. The Company began the  process
    of  closing the nine PI distribution centers  in April, 1996, and expects to
    begin closing the last of such distribution centers by October, 1996.
    
 
        (b) These cost  savings are  directly associated  with the  distribution
    centers  and  other  facilities  expected to  be  closed  subsequent  to the
    Acquisition. Such cost savings relate primarily to rent, utilities,  repairs
    and  maintenance, property taxes and other  direct costs associated with the
    closed facilities.
 
   
        (c) In May, 1996,  the Company plans to  discontinue PI's benefit  plans
    and  to allow active PI employees to  enroll in the Company's benefit plans,
    which have lower per participant costs.

                                    BUSINESS
 
COMPANY OVERVIEW
 
   
    The Company is  a leading  warehouse distributor  of automotive  replacement
parts  in  the  United  States,  supplying  over  1,900  parts  stores  owned by
associated jobbers and approximately  325 Company-owned stores  as of April  25,
1996.  The Company  principally serves the  wholesale segment  of the automotive
parts aftermarket. Through the Company's  network of 35 distribution centers  in
30  states, the  Company offers  over 160,000 SKUs,  including a  broad array of
nationally  recognized  replacement  parts,   tools,  equipment,  supplies   and
accessories under its Big A brand name as well as manufacturers' brands and, for
a  limited time through  the distribution centers  owned by PI,  under the Parts
Plus group  of brand  names. In  addition, as  of April  25, 1996,  the  Company
operated  more than 250 ISWs, which directly serve the needs of the professional
installer by stocking a  select number of high  demand products and  emphasizing
availability  and quick delivery. The Company had net sales and EBITDA of $603.7
million and $38.7 million, respectively, for  the fiscal year ended January  27,
1996  and $217.6 million  and $11.9 million, respectively,  for the three months
ended  April  25,  1996.  Excluding  the  $11.2  million  asset  impairment  and
restructuring  charge recorded  by the Company  in the fourth  quarter of fiscal
1996, the Company would  have had EBITDA  of $50.0 million  for the fiscal  year
ended  January 27, 1996. See "Management's  Discussion and Analysis of Financial
Condition and Results of Operations --  Results of Operations" in the Form  10-K
and  in the  Form 10-Q, each  of which  is incorporated herein  by reference and
"Selected  Historical  Consolidated   Financial  Information   of  APS   Holding
Corporation."
    
 
    The  Company's Big A program  offers a number of  benefits to the associated
jobbers that participate  in the  program, including  (i) a  broad selection  of
product   lines;  (ii)  brand  name  identity,  including  national  advertising
programs; (iii) access to flexible purchasing programs; (iv) overnight  delivery
of  parts; and (v) a comprehensive  package of services, including assistance in
marketing, cataloging,
 
                                       39

inventory control, accounting, management  and employee training.  Approximately
two-thirds  of  the Company's  associated jobbers  and Company-owned  stores are
located in communities with populations of less than 25,000 people. The  Company
believes  that jobbers located in smaller communities are well suited to the Big
A program because the  customer base within these  communities generally is  not
large enough to support the investment necessary to enable a jobber to obtain on
its own the benefits of the Big A program. In contrast, ISWs target customers in
larger  metropolitan  areas typically  not  served by  the  Company's associated
jobbers or Company-owned stores  by focusing on a  select number of high  demand
products  (typically undercar products such as chassis, suspension, steering and
brake parts) and emphasizing availability and quick delivery.
    
 
   
    On the Acquisition Closing Date, APS acquired all of the outstanding capital
stock PI, an  automotive parts distributor,  from GKN Parts  for a cash  closing
purchase  price of  $79.7 million,  which purchase  price was  adjusted to $74.9
million  after  the  closing.  As  of  the  Acquisition  Closing  Date,  the  PI
distribution  network was comprised  of approximately 850  parts stores owned by
PI's associated jobbers and more  than 125 company-owned stores operating  under
the  Parts Plus group of marks, which were serviced through PI's 14 distribution
centers. As of the  Acquisition Closing Date, PI's  customer base was  primarily
located  in markets where the Company had a relatively minor presence, including
Arkansas, Oklahoma,  Texas,  Tennessee,  Kentucky,  Mississippi,  Alabama,  West
Virginia  and Michigan. Based  on the Company's  review of PI's  store base, the
Company believes that as of such date, there was less than a 5% overlap  between
the  Company's and PI's associated jobbers and company-owned stores. The Company
believes that opportunities exist to achieve significant ongoing purchasing  and
other  cost savings  in connection with  the Acquisition,  including through the
closure  (as  of  the  date  of  this  Prospectus)  of  four  of  the  Company's
distribution centers (including two PI distribution centers) and the anticipated
closure  of seven additional  PI distribution centers,  and the consolidation of
these operations into the combined  companies' remaining facilities. PI had  net
sales  and  EBITDA of  $224.8 million  and $5.0  million, respectively,  for the
fiscal year  ended  December 31,  1995.  See  "Risk Factors  --  Realization  of
Benefits from the Acquisition; Integration of PI," "Pro Forma Combined Condensed
Statement  of Operations"  and the  Financial Statements  of PI  and the related
notes thereto for the fiscal year ended December 31, 1995.
    
 
    In February 1996, the Company sold its  interest in the Parts Plus group  of
marks,  which  had been  acquired  by the  Company  in the  Acquisition,  to the
Association of Automobile  Aftermarket Distributorships  ("AAAD"), a  programmed
distribution  group that  markets automotive  replacement parts  under the Parts
Plus program, for cash consideration of $3.5 million. PI had previously licensed
the same marks  to AAAD for  a small yearly  license fee. Pursuant  to the  sale
agreement,  PI associated  jobbers who have  not yet  changed over to  the Big A
program will be entitled to continue to use  the Parts Plus group of marks on  a
royalty  free basis, and  to receive all  of the economic  benefits of the Parts
Plus program, for 450 days following the closing of the Acquisition. The Company
intends to gradually change over  PI's distribution centers, associated  jobbers
and company-owned stores to the Big A program during fiscal 1997, beginning with
the  PI  distribution  centers, and  the  associated jobbers  serviced  by those
distribution centers, that the Company expects to close.

                      DESCRIPTION OF NEW CREDIT AGREEMENT
 
   
    In  connection with the Acquisition, the Company entered into the New Credit
Agreement with  Chemical and  certain other  lenders. The  New Credit  Agreement
replaced  the credit  facilities that  were available  to the  Company under the
Prior Credit  Agreement. The  New  Credit Agreement  provides  for a  Term  Loan
Facility  of $65 million and a Revolving Credit Facility of $235 million, with a
final maturity date  of December  31, 1999  for the  Term Loan  Facility and  of
December   31,  2000  for  the  Revolving  Credit  Facility  (collectively,  the
"Facilities"). Up to $20 million  of Revolving Credit Facility availability  may
be  used  for standby  and  commercial letters  of  credit, and  $10  million of
Revolving Credit Facility  availability may be  used for swing  line loans.  The
Facilities  were  used to  replace the  Prior Credit  Agreement and  finance the
working  capital  and  business  requirements  of  the  Company  following   the
Acquisition.  See  "Use  of  Proceeds." Borrowings  under  the  Revolving Credit
Facility are subject to a borrowing  base limitation based on eligible  accounts
receivable and inventory.
    
 
    Pursuant  to  the New  Credit  Agreement, the  Company  is required  to make
quarterly principal  payments  on the  term  loan borrowings  thereunder  in  an
aggregate  amount of $13  million in 1996,  $15 million in  1997, $17 million in
1998 and  $20 million  in 1999.  The Facilities  are also  subject to  mandatory
prepayments and reductions, subject to certain exceptions, in an amount equal to
100%  of the net proceeds of certain permitted asset sales and certain issuances
of debt obligations of the Company. Such  net proceeds will be applied first  to
prepay term loans and then to prepay swing line loans and revolving credit loans
(and   cash  collateralize  or  replace   outstanding  letters  of  credit)  and
simultaneously reduce the Revolving Credit  Facility. On December 31, 2000,  all
remaining  amounts then outstanding  under the New  Credit Agreement will become
due.
 
   
    Loans under the Facilities generally bear interest, at the Company's option,
at a rate equal to either (i) the  rate that is the highest of Chemical's  prime
rate  or certain alternative rates ("Base Rate"),  in each case plus a margin of
up to 0.75% per annum, or (ii) the rate at which certain Eurodollar deposits are
offered in the  interbank Eurodollar  market ("LIBOR") plus  a margin  of up  to
2.00% per annum. The margin applicable to the Base Rate loans currently is 0.25%
per  annum, while the  margin applicable to  LIBOR loans currently  is 1.50% per
annum.
    
 
    The Company's obligations under the  New Credit Agreement are guaranteed  by
Holding  and certain of  the subsidiaries of  APS and secured  by pledges of the
capital  stock  of  APS  and   such  subsidiaries,  by  security  interests   in
substantially  all of  their personal  property and  by mortgages  on certain of
their owned real property.
 
    The New Credit  Agreement contains  (i) customary  or otherwise  appropriate
default  provisions, including provisions for default if CD&R and its affiliates
transfer to a  third party  any of  the shares of  the common  stock of  Holding
currently  held by Fund IV,  or if any other person  or group acquires more than
30% of the outstanding shares of the common stock of Holding, and (ii) customary
or  otherwise  appropriate  affirmative  and  negative  covenants,  including  a
negative  pledge with  respect to unencumbered  assets, and  restrictions on the
ability of APS and its subsidiaries to incur indebtedness, incur liens and other
encumbrances, pay dividends or make other restricted payments, become liable  on
guarantees  and other contingent obligations, enter into agreements with respect
to mergers  or consolidations,  sell  or transfer  assets, make  investments  or
capital  expenditures, make  acquisitions, make  loans and  advances, enter into
transactions with affiliates, and create subsidiaries or engage in new types  of
business.  In addition,  the New  Credit Agreement  contains financial covenants
requiring the  maintenance  of certain  financial  ratios and  tests,  including
maintenance  of the  Company's net worth  and maintenance  of consolidated fixed
charge to  interest expense  and  consolidated leverage  ratios,  as well  as  a
limitation on capital expenditures.
 
                            DESCRIPTION OF THE NOTES
 
   
    The  Existing Notes were, and the New  Notes will be, issued pursuant to the
Indenture. The terms  of the  Notes include those  stated in  the Indenture  and
those  made part of the Indenture by reference to the Trust Indenture of 1939 as
in  effect  on   the  date   the  Indenture   is  qualified   under  the   Trust
    
 
                                       41
<PAGE>
   
Indenture  Act (the "Trust Indenture Act";  PROVIDED, HOWEVER, that in the event
that the Trust Indenture Act is  amended after such date, "Trust Indenture  Act"
means,  to the extent required by any such amendment, the Trust Indenture Act of
1939 as so amended).  The Notes are  subject to all such  terms, and holders  of
Notes  are referred to the Indenture and the Trust Indenture Act for a statement
of those terms.
    
 
    For purposes of  this description, the  term Holding refers  to APS  Holding
Corporation  and does  not include its  Subsidiaries, and APS  refers to A.P.S.,
Inc. and does not include its Subsidiaries, in each case, except for purposes of
financial data determined on a consolidated basis.
 
    The following  summary  of certain  provisions  of the  Indenture  does  not
purport to be complete and is subject to the provisions of the Indenture and the
Notes,   including  the  definitions  therein   of  certain  terms  used  below.
Capitalized terms used in this section and not otherwise defined in this section
have the respective meanings assigned to them in the Indenture. Certain  defined
terms are set forth below under " -- Certain Definitions."
 
GENERAL
 
   
    The  Existing  Notes  are, and  the  New  Notes will  be,  general unsecured
obligations of  APS and  together  will be  limited  to $100  million  aggregate
principal amount. The payment of principal, premium, if any, and interest on the
Existing Notes is, and in the New Notes will be, unconditionally guaranteed on a
senior  subordinated and  unsecured basis  by Holding  and by  each existing and
future Restricted  Subsidiary Guarantor  (Holding and  the existing  and  future
Restricted  Subsidiary Guarantors of Holding are referred to collectively as the
"Note Guarantors"), and  Holding will  cause each  future Restricted  Subsidiary
Guarantor  to enter  into a  supplemental indenture  providing for  a Restricted
Subsidiary Guarantee as required in the Indenture.
    
 
FORM, DENOMINATION AND BOOK-ENTRY PROCEDURES
 
    The Existing Notes held by  Qualified Institutional Buyers pursuant to  Rule
144A  are represented  by a fully  registered global note  (the "Existing Global
Note" and, together with the New  Global Certificates, the "Global Notes").  The
Existing Global Note has been deposited with a Participant (as defined below) as
custodian  for DTC  and registered  in the  name of  Cede &  Co., DTC's nominee.
Except as set forth below, the Existing Global Note may be transferred, in whole
and in part, only to another nominee of the Depositary or to a successor of  the
Depositary or its nominee.
 
    The  Existing  Notes  held  by  Institutional  Accredited  Investors  and by
non-U.S. persons who purchased such Notes outside the United States pursuant  to
Regulation  S are represented by Existing Notes in registered, certificated form
without  interest  coupons.   Such  Existing  Notes   are  subject  to   certain
restrictions  on transfer  as described under  "Risk Factors  -- Restrictions on
Transfer."
 
    At the option of the holder of a New Note, such New Note may be held in  the
form  of either (i) a certificated New Note or (ii) a beneficial interest in one
or more New Global Certificates. The  New Notes initially represented by one  or
more  fully  registered  New  Global Certificates  will  be  deposited  with the
Depositary and registered  in the  name of the  Depositary or  its nominee  (the
"Global  Certificate  Registered Owner").  Except  in the  limited circumstances
described below, the New Global Certificate may be transferred, in whole and not
in part, only  to another nominee  of the Depositary  or to a  successor of  the
Depositary or its nominee.
 
    The Depositary is a limited-purpose trust company created to hold securities
for  its participating  organizations (collectively, the  "Participants") and to
facilitate the  clearance and  settlement of  transactions in  those  securities
between  Participants through electronic  book-entry changes in  accounts of its
Participants. The Participants include securities brokers and dealers (including
the Initial Purchasers of the Existing Notes), banks (including The Bank of  New
York),  trust companies, clearing corporations  and certain other organizations.
Indirect access to the Depositary's system  is also available to other  entities
such  as  banks, brokers,  dealers  and trust  companies  that clear  through or
maintain custodial relationship with a Participant (collectively, the  "Indirect
Participants"). Persons who are not Participants may beneficially own securities
held by or on behalf of the Depositary only
 
                                       42
<PAGE>
through  the Participants or  the Indirect Participants.  The ownership interest
and transfer of  ownership interest of  each actual purchaser  of each  security
held  by or  on behalf  of the  Depositary are  recorded on  the records  of the
Participants and Indirect Participants.
 
    The Depositary will take  any action permitted  to be taken  by a holder  of
Notes (including the presentation of Notes for exchange as described below) only
at  the direction of one or more Participants to whose accounts interests in the
Global Note are credited and  only in respect of  such portion of the  aggregate
principal  amount of Notes as  to which such Participant  or Participants has or
have given such direction.
 
    APS expects that the Depositary or its nominee, upon receipt of any  payment
of  principal, premium or  interest in respect  of the Global  Note, will credit
Participants'  accounts  with   payments  in  amounts   proportionate  to   such
Participants'  respective beneficial  interests in  the principal  amount of the
Global Note, as shown on the records of the Depositary or its nominee. APS  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 practices,  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. The
laws of  some states  require that  certain persons  take physical  delivery  in
definitive  form  of  securities that  they  own. Consequently,  the  ability to
transfer Notes will be limited to that extent.
 
    Except as described  below, owners of  interests in a  Global Note will  not
have  Notes registered  in their  names, will  not receive  physical delivery of
Notes in  definitive form  and will  not be  considered the  Global  Certificate
Registered Owners thereof under the Indenture for any purpose.
 
    Although  the Depositary  and its  Participants are  expected to  follow the
foregoing procedures in order to facilitate transfers of interests in the Global
Note among Participants, they are under no obligation to perform or continue  to
perform  such procedures, and  such procedures may be  discontinued at any time.
None of  the Company,  the  Trustee, the  Paying Agent,  nor  any agent  of  the
Company,  the  Trustee  or the  Paying  Agent  will have  any  responsibility or
liability for (i) any  aspect of the Depositary's  records or any  Participant's
records  relating  to  or  payments  made  on  account  of  beneficial ownership
interests in a Global Note, or for maintaining, supervising or reviewing any  of
the Depositary's records or any Participant's records relating to the beneficial
ownership  interests in a Global  Note or (ii) any  other matter relating to the
actions and practices of the Depositary, of  any of its Participants, or of  any
of the Indirect Participants.
 
    Payments  in  respect of  the principal  of  and interest  on any  New Notes
registered in  the  name of  the  Global  Certificate Registered  Owner  on  the
relevant  record date will be  payable by the Trustee  to the Global Certificate
Registered Owner in its  capacity as the registered  owner under the  Indenture.
Under  the terms of the Indenture, the Company, the Trustee and the Paying Agent
will treat the person  in whose names  the Notes, including  a Global Note,  are
registered  as the owners thereof for the purpose of receiving such payments and
for any and all  other purposes whatsoever.  Consequently, neither the  Company,
the  Trustee, the Paying Agent nor any agent  of the Company, of the Trustee, or
of the Paying Agent  has or will  have any responsibility  or liability for  the
payment  of such amounts to  beneficial owners of Notes  or for any other matter
relating to actions or practices of  the Depositary or any of its  Participants.
None  of the  Company, the Trustee  or the Paying  Agent will be  liable for any
delay by the Depositary or any of its Participants in identifying the beneficial
owners of the  Notes, and  the Company,  the Trustee  and the  Paying Agent  may
conclusively  rely on and will be protected  in relying on instructions from the
Global Certificate Registered Owner for all purposes.
 
   
    Owners of  beneficial interests  in  the Global  Note  will be  entitled  to
receive  certificated Notes, if (i)  the Depositary is at  any time unwilling or
unable to continue  as, or ceases  to be, a  "clearing agency" registered  under
Section 17A of the Exchange Act, and a successor to the Depositary registered as
a  "clearing agency" under Section  17A of the Exchange  Act is not appointed by
APS within 90 days or
    
 
                                       43
<PAGE>
(ii) in the case of the Existing Global Note only, as provided in the  following
paragraph.  In addition to the foregoing, on or after the occurrence of an Event
of Default under  the Indenture, owners  of beneficial interests  in the  Global
Note will be entitled to request and receive certificated Notes.
 
    Subject  to the  restrictions on the  transferability of  the Existing Notes
described in "Risk  Factors -- Restrictions  on Transfer," an  Existing Note  in
definitive  form will be issued upon the resale, pledge or other transfer of any
Existing Note  or  interest therein  to  any person  or  entity that  is  not  a
Qualified Institutional Buyer pursuant to Rule 144A or that does not participate
in the Depositary.
 
    The information in this section concerning the Depositary and its book-entry
system  has been obtained from sources that the Company believes to be reliable,
but the Company takes no responsibility for the accuracy thereof.
 
NOTE GUARANTEES
 
    The Holding Guarantee and  the Restricted Subsidiary Guarantees  irrevocably
and  unconditionally guarantee  the performance  and punctual  payment when due,
whether at Stated  Maturity, by  acceleration, in  connection with  a Change  of
Control  Offer, an  Excess Proceeds  Offer or  redemption, or  otherwise, of all
obligations of APS  under the Indenture  and the Notes,  whether for payment  of
principal   of,  premium,   if  any,  or   interest  on   the  Notes,  expenses,
indemnification or otherwise. Each of the Note Guarantors has agreed to pay,  in
addition  to any amount stated above, any and all expenses (including reasonable
counsel fees and expenses) incurred by  the Trustee or the Holders in  enforcing
any  rights under the Holding Guarantee or the Restricted Subsidiary Guarantees.
Each of the Note Guarantees are limited in amount to an amount not to exceed the
maximum amount that can  be guaranteed by Holding  or the applicable  Restricted
Subsidiary Guarantor without rendering such Note Guarantee as it relates to such
Note  Guarantor voidable under applicable  law relating to fraudulent conveyance
or fraudulent  transfer  or  similar  laws affecting  the  rights  of  creditors
generally.
 
    Each  of the Holding Guarantee and the Restricted Subsidiary Guarantees is a
continuing Guarantee and (a) shall remain in full force and effect until payment
in full of the aggregate  outstanding principal amount of  the Notes and all  of
APS's  other obligations then due and payable  under the Indenture and the Notes
or, in  the case  of a  Restricted Subsidiary  Guarantee, upon  such  Restricted
Subsidiary  Guarantor no longer being a  Restricted Subsidiary Guarantor, (b) is
binding upon each of the Note Guarantors  and (c) is granted for the benefit  of
and be enforceable by the Trustee and the holders of Notes.
 
PAYMENT TERMS
 
   
    The  Notes will mature  on January 15, 2006  and bear interest  at a rate of
11 7/8 % per annum until maturity,  payable semiannually on January 15 and  July
15  of each year,  commencing July 15,  1996, to the  Persons who are registered
Holders of Notes at the close of business on the January 1 or July 1 immediately
preceding such interest payment date.
    
 
    The Indenture provides that interest on the  Notes is to be computed on  the
basis of a 360-day year of twelve 30-day months. Initially, the Trustee will act
as  Paying Agent and Registrar. Principal and interest will be payable initially
at the offices of the  Paying Agent but, at the  option of APS, interest may  be
paid by check mailed to the Persons who are registered holders of Notes at their
registered  addresses, except  that payments in  respect of the  Global Note (as
defined below) will be made to the Depositary in next-day funds. Holding or  any
of  its  Subsidiaries  or Affiliates  may  act  as Paying  Agent  and Registrar,
PROVIDED that Holding  shall, or shall  cause such Subsidiary  or Affiliate  to,
segregate  and hold in  trust for the benefit  of the Holders  all funds held by
such Person  as Paying  Agent. APS  may  change the  Paying Agent  or  Registrar
without prior notice to holders of Notes.
 
SUBORDINATION OF NOTES
 
    The  Existing Notes are, and the New Notes will be, subordinated in right of
payment, as set forth in the Indenture, to the prior payment in full in cash  or
cash  equivalents of  all existing  and future  Senior Indebtedness  of APS. The
Notes  shall  in   all  respects  rank   PARI  PASSU  with   all  other   Senior
 
                                       44
<PAGE>
   
Subordinated  Indebtedness of APS,  and only Indebtedness of  APS that is Senior
Indebtedness of  APS shall  rank senior  to the  Notes. Although  the  Indenture
limits  the aggregate amount of additional  Indebtedness that APS may Incur, the
Indenture does not  limit the  amount of such  Indebtedness that  may be  Senior
Indebtedness  of  APS. In  the  event of  bankruptcy,  liquidation, dissolution,
reorganization or  any similar  proceeding of  APS, the  assets of  APS will  be
available  to make payments on  the Notes only after  all Senior Indebtedness of
APS has been paid  in full in cash  or cash equivalents or  in any other  manner
acceptable  to  the  holders  of  Senior  Indebtedness,  and  there  may  not be
sufficient assets remaining to pay amounts due on all or any of the Notes. As of
April 25,  1996, there  was $204.4  million of  Senior Indebtedness  of APS,  no
Senior  Subordinated Indebtedness of APS (other  than the Existing Notes) and no
Subordinated Obligations of APS outstanding; and assuming the full  availability
and  incurrence by APS of  the full $94.9 million that  was then available to be
borrowed under the New Credit Agreement, there would have been $299.3 million of
Senior Indebtedness of APS outstanding.
    
 
    Upon any payment or distribution  of the assets of  APS to creditors upon  a
total  or partial liquidation or  a total or partial dissolution  of APS or in a
bankruptcy,  reorganization,  insolvency,  receivership  or  similar  proceeding
relating to APS or its property: (i) holders of Senior Indebtedness of APS shall
be  entitled to receive payment in full of the Senior Indebtedness of APS before
holders of Notes shall  be entitled to  receive any payment  of principal of  or
interest  on the Notes; and (ii) until the Senior Indebtedness of APS is paid in
full, any distribution to which holders of Notes would be entitled but for  this
provision  shall  be made  to holders  of  Senior Indebtedness  of APS  as their
interests may appear, except that holders of Notes may receive Permitted  Junior
Securities.
 
    In the event that (i) any Senior Indebtedness of APS is not paid when due or
(ii)  any other  default on  Senior Indebtedness  of APS  occurs and  the Stated
Maturity of such Senior  Indebtedness of APS is  accelerated in accordance  with
its  terms, then, APS may not pay the principal of, premium, if any, interest on
or any other amounts owing in respect of  the Notes or make any deposit for  the
purpose  of the  discharge of  its liabilities under  the Indenture  and may not
repurchase, redeem or otherwise retire any Notes (collectively, "pay the Notes")
unless, in either case, (a)  the default has been cured  or waived and any  such
acceleration  has been rescinded or (b) such Senior Indebtedness of APS has been
paid in full. In addition, during the  continuance of any default (other than  a
default  described in clause (i) or (ii) of the preceding sentence) with respect
to any Designated Senior  Indebtedness of APS  as a result  of which the  Stated
Maturity  thereof  may then  be accelerated  immediately without  further notice
(except such  notice as  may be  required to  effect such  acceleration) or  the
expiration  of any  applicable grace periods,  APS may  not pay the  Notes for a
period (a "Payment Blockage Period") commencing upon the receipt by APS and  the
Trustee  of  written  notice of  such  default  from the  Representative  of any
Designated Senior Indebtedness of APS specifying an election to effect a Payment
Blockage Period (a "Blockage Notice") and ending 179 days thereafter (or earlier
if such  Payment Blockage  Period is  terminated (i)  by written  notice to  the
Trustee  and APS from the Representative who  gave such Blockage Notice, (ii) by
repayment in full of such Designated Senior Indebtedness of APS or (iii) because
the default  giving rise  to  such Blockage  Notice  is no  longer  continuing).
Notwithstanding  the provisions described in  the immediately preceding sentence
(but subject to the provisions contained in the next preceding sentence), unless
the holders of such Designated Senior Indebtedness of APS or the  Representative
of  such holders shall  have accelerated the Stated  Maturity of such Designated
Senior Indebtedness of  APS, APS  may resume payments  on the  Notes after  such
Payment  Blockage Period. Not more than one  Blockage Notice may be given in any
consecutive 360-day period, irrespective of the number of defaults with  respect
to Designated Senior Indebtedness of APS during such period.
 
    The  provisions described in the two  preceding paragraphs shall not prevent
or delay  the receipt  by the  holders of  Notes of  payments of  principal  and
interest  on the Notes, as described below under "-- Satisfaction and Discharge;
Defeasance," from the  application of  any cash or  U.S. Government  Obligations
held in trust by the Trustee.
 
                                       45
<PAGE>
    In  the event of APS's  insolvency, liquidation, reorganization, dissolution
or other similar proceedings, funds that  would otherwise be payable to  holders
of  Notes  will be  paid to  the holders  of Senior  Indebtedness to  the extent
necessary to pay the Senior Indebtedness of APS in full. Moreover, creditors  of
APS  pursuant to obligations (such as  accounts payable or tax liabilities) that
are neither Senior Indebtedness of  APS nor Senior Subordinated Indebtedness  of
APS  may recover less, ratably,  than the holders of  Senior Indebtedness of APS
but may recover more, ratably, than holders of Senior Subordinated  Indebtedness
of APS, including the holders of Note.
 
    In  addition to  ranking senior in  right of  payment to the  Notes, the New
Credit Agreement is secured by substantially all the assets of APS. In the event
of any  payment  or  distribution of  the  assets  of APS  in  any  foreclosure,
dissolution,  winding up, liquidation  or reorganization, the  lenders under the
New Credit Agreement and any other secured Senior Indebtedness of APS will  have
a  secured prior claim  to such assets  of APS. The  Indenture does not restrict
Liens granted by APS to secure Senior Indebtedness.
 
SUBORDINATION OF NOTE GUARANTEES; RELEASE OF RESTRICTED SUBSIDIARY GUARANTEES
 
   
    The  Holding  Guarantee  and   each  Restricted  Subsidiary  Guarantee   are
subordinated  in right of payment,  as set forth in  the Indenture, to the prior
payment in full of all existing and future Senior Indebtedness of the Holding or
such Restricted Subsidiary Guarantor, as the case may be. The Holding  Guarantee
and  each Restricted Subsidiary Guarantee, in all respects, rank PARI PASSU with
all other  Senior  Subordinated  Indebtedness  of  Holding  or  such  Restricted
Subsidiary  Guarantor, as the  case may be,  and only Indebtedness  of such Note
Guarantor that is Senior Indebtedness  of Holding or such Restricted  Subsidiary
Guarantor,  as the  case may  be, rank  senior to  the Holding  Guarantee or the
relevant Restricted  Subsidiary Guarantee,  as  the case  may be.  Although  the
Indenture  limits the aggregate amount of  additional Indebtedness that the Note
Guarantors  may  Incur,  the  Indenture  does  not  limit  the  amount  of  such
Indebtedness  that may  be Senior Indebtedness  of a Holding  or such Restricted
Subsidiary  Guarantor,  as  the  case  may  be.  In  the  event  of  bankruptcy,
liquidation  or  reorganization of  a Note  Guarantor, the  assets of  such Note
Guarantor will be available to make payments under the Holding Guarantee or  the
relevant  Restricted Subsidiary  Guarantee, as the  case may be,  only after all
Senior Indebtedness of Holding or  such Restricted Subsidiary Guarantor, as  the
case  may be,  has been  paid in full,  and there  may not  be sufficient assets
remaining to  pay  amounts due  on  the  Holding Guarantee  and  the  Restricted
Subsidiary  Guarantees. As of April 25, 1996, there was $202.9 million of Senior
Indebtedness of  Holding  (including  Holding's  guarantee  of  the  New  Credit
Agreement)  and  $203.8  million  in the  aggregate  of  Senior  Indebtedness of
Restricted Subsidiary Guarantors  (including their guarantee  of the New  Credit
Agreement)  outstanding  to  which  the  Holding  Guarantee  and  the Restricted
Subsidiary  Guarantees,  as  the  case  may  be,  was  subordinated,  no  Senior
Subordinated  Indebtedness of Holding  (other than the  Holding Guarantee) or of
the Restricted  Subsidiary  Guarantors  (other than  the  Restricted  Subsidiary
Guarantees)  and  no  Subordinated  Obligations  of  Holding  or  the Restricted
Subsidiary Guarantors  outstanding;  and  assuming  the  full  availability  and
incurrence  by  APS of  the full  $94.9 million  that was  then available  to be
borrowed under the New Credit Agreement  as of such date, the Holding  Guarantee
would have been subordinated to $297.8 million of Senior Indebtedness of Holding
(including  Holding's guarantee of the New  Credit Agreement) and the Restricted
Subsidiary Guarantees  would have  been subordinated  to $298.7  million in  the
aggregate  of Senior Indebtedness of Restricted Subsidiary Guarantors (including
their guarantee of the New Credit Agreement).
    
 
    Upon any payment  or distribution  of the assets  of any  Note Guarantor  to
creditors  upon a total or partial liquidation or a total or partial dissolution
of  such  Note  Guarantor  or  in  a  bankruptcy,  reorganization,   insolvency,
receivership  or  similar  proceeding relating  to  such Note  Guarantor  or its
property: (i)  holders of  Senior  Indebtedness of  Holding or  such  Restricted
Subsidiary  Guarantor, as the case may be,  shall be entitled to receive payment
in full of  the Senior  Indebtedness of  Holding or  such Restricted  Subsidiary
Guarantor,  as the  case may be,  before holders  of Notes shall  be entitled to
receive any  payment under  the  Holding Guarantee  or the  relevant  Restricted
Subsidiary Guarantee,
 
                                       46
<PAGE>
as  the case may be;  and (ii) until the Senior  Indebtedness of Holding or such
Restricted Subsidiary  Guarantor, as  the case  may  be, is  paid in  full,  any
distribution to which Noteholders would be entitled but for this provision shall
be  made  to  holders  of  Senior Indebtedness  of  Holding  or  such Restricted
Subsidiary Guarantor, as the case may be, as their interests may appear,  except
that Noteholders may receive Permitted Junior Securities.
 
    In  the event that (i) any Senior Indebtedness of Holding or such Restricted
Subsidiary Guarantor, as the case may be, is not paid when due or (ii) any other
default  on  Senior  Indebtedness  of  Holding  or  such  Restricted  Subsidiary
Guarantor,  as the case  may be, occurs  and the Stated  Maturity of such Senior
Indebtedness of Holding or such Restricted Subsidiary Guarantor, as the case may
be, is accelerated in accordance with  its terms, then, such Note Guarantor  may
not  pay  the  Notes  pursuant  to  the  Holding  Guarantee  or  such Restricted
Subsidiary Guarantee, as the case may be unless, in either case, (a) the default
has been cured or  waived and any  such acceleration has  been rescinded or  (b)
such  Senior  Indebtedness  has  been  paid in  full.  In  addition,  during the
continuance of any default (other than a default described in clause (i) or (ii)
of the preceding sentence) with respect to any Designated Senior Indebtedness of
Holding or such Restricted Subsidiary Guarantor, as the case may be, as a result
of which the Stated Maturity thereof may then be accelerated immediately without
further  notice  (except  such  notice  as  may  be  required  to  effect   such
acceleration)  or  the expiration  of any  applicable  grace periods,  such Note
Guarantor may not pay  the Notes for a  Payment Blockage Period commencing  upon
the  receipt by  such Note Guarantor  and the  Trustee of a  Blockage Notice and
ending 179  days thereafter  (or  earlier if  such  Payment Blockage  Period  is
terminated (i) by written notice to the Trustee and such Note Guarantor from the
Representative  who gave such Blockage Notice, (ii) by repayment in full of such
Designated Senior Indebtedness of  such Guarantor or  (iii) because the  default
giving  rise to such  Blockage Notice is  no longer continuing). Notwithstanding
the provisions described in the  immediately preceding sentence (but subject  to
the  provisions contained in the next preceding sentence), unless the holders of
such Designated Senior  Indebtedness of  Holding or  such Restricted  Subsidiary
Guarantor,  as the case may be, or the Representative of such holders shall have
accelerated the  Stated  Maturity  of such  Designated  Senior  Indebtedness  of
Holding  or such Restricted Subsidiary Guarantor, as  the case may be, such Note
Guarantor may resume  payments under  the Holding Guarantee  or such  Restricted
Subsidiary  Guarantee, as the  case may be, after  such Payment Blockage Period.
Not more  than one  Blockage Notice  may  be given  in any  consecutive  360-day
period, irrespective of the number of defaults with respect to Designated Senior
Indebtedness of Holding or such Restricted Subsidiary Guarantor, as the case may
be, during such period.
 
    In  the  event of  insolvency,  liquidation, reorganization,  dissolution or
other similar proceedings with respect to  any Note Guarantor, funds that  would
otherwise  be  payable to  Noteholders will  be  paid to  the holders  of Senior
Indebtedness of Holding or such Restricted Subsidiary Guarantor, as the case may
be, to the extent necessary to  pay such Senior Indebtedness in full.  Moreover,
creditors  of  such Note  Guarantor pursuant  to  obligations (such  as accounts
payable  or  tax  liens)  that  are  neither  Senior  Indebtedness  nor   Senior
Subordinated Indebtedness of Holding or such Restricted Subsidiary Guarantor, as
the  case may be, may recover less, ratably, than holders of Senior Indebtedness
of Holding or such Restricted Subsidiary Guarantor, as the case may be, but  may
recover  more,  ratably, than  holders  of Senior  Subordinated  Indebtedness of
Holding or such Restricted Subsidiary Guarantor,  as the case may be,  including
the Noteholders.
 
    In  addition to ranking senior  in right of payment  to the Note Guarantees,
the Senior Indebtedness of the Note Guarantors under the New Credit Agreement is
secured by  substantially all  the assets  of Holding  (principally the  Capital
Stock  of APS) and its Restricted Subsidiaries  (including APS). In the event of
any payment  or  distribution  of  the  assets of  any  Note  Guarantor  in  any
foreclosure,  dissolution, winding up, liquidation or reorganization, holders of
secured Senior Indebtedness of such guarantor will have a secured prior claim to
such assets of such guarantor.
 
                                       47
<PAGE>
    Any claims  by Noteholders  against the  assets of  Subsidiaries of  Holding
(other  than  Restricted  Subsidiaries  by  reason  of  their  being  Restricted
Subsidiary Guarantors) would  be structurally subordinated  to all existing  and
future  obligations (including  trade payables and  preferred stock,  if any) of
such Subsidiaries.
 
    In the event  of a sale  or other disposition  of all of  the assets of  any
Restricted  Subsidiary Guarantor, by way  of merger, consolidation or otherwise,
or a sale or  other disposition of  all of the Capital  Stock of any  Restricted
Subsidiary  Guarantor,  by  way  of  merger,  consolidation  or  otherwise, such
Restricted Subsidiary Guarantor (in the event of a sale or other disposition  of
all  of  the Capital  Stock  of such  Restricted  Subsidiary Guarantor)  will be
released and  relieved  of  its  obligations  under  its  Restricted  Subsidiary
Guarantee  or the Person acquiring the property (in the event of a sale or other
disposition of all of the assets  of such Restricted Subsidiary Guarantor)  will
not  be required to  enter into a Restricted  Subsidiary Guarantee, PROVIDED, in
each case, that such  transaction is carried out  pursuant to and in  accordance
with  "--  Certain Covenants  -- Limitation  on Sales  of Assets  and Restricted
Subsidiary Stock"  and, if  applicable, "--  Merger, Consolidation  and Sale  of
Assets" below.
 
OPTIONAL REDEMPTION
 
    Except as described below, the Notes will not be redeemable at the option of
APS  prior  to January  15, 2001.  On and  after  that date,  the Notes  will be
redeemable at the option of APS,  in whole at any time  or in part from time  to
time,  on  at least  30  but not  more  than 60  days'  prior notice,  mailed by
first-class mail to  the Noteholders'  registered addresses,  at the  redemption
prices  (expressed  in percentages  of  principal amount)  specified  below plus
accrued and unpaid  interest (if  any) to the  redemption date  (subject to  the
right  of each Holder of record on  the relevant record date to receive interest
due on the  relevant interest  payment date),  if redeemed  during the  12-month
period beginning January 15 of the years indicated below:

    In  addition, at any time  and from time to time  prior to January 15, 1999,
APS may  redeem  in the  aggregate  up to  33  1/3% of  the  original  aggregate
principal  amount of the  Notes with the  proceeds of one  or more Public Equity
Offerings by Holding, on at  least 30 but not more  than 60 days' prior  notice,
mailed  by  first-class  mail to  the  Noteholders' registered  addresses,  at a
redemption price  (expressed as  a percentage  of principal  amount thereof)  of
111.875%,  plus,  in each  case, accrued  and  unpaid interest,  if any,  to the
redemption date (subject to the right of  each Holder of record on the  relevant
record  date to  receive interest  due on  the relevant  interest payment date);
PROVIDED, HOWEVER, that  at least 66  2/3% of the  original aggregate  principal
amount of the Notes must remain outstanding after each such redemption.
 
    The  Notes  will be  subject to  redemption at  the option  of APS  prior to
January 15, 2001,  in whole  or in part,  at any  time within 180  days after  a
Change  of Control on  not less than 30  nor more than 60  days' prior notice to
each Holder of Notes to be redeemed, at  a redemption price equal to the sum  of
(i)  the principal  amount thereof plus  (ii) the Applicable  Premium plus (iii)
accrued and unpaid  interest, if  any, to the  redemption date  (subject to  the
right  of each Holder of record on  the relevant record date to receive interest
due on  the relevant  interest payment  date). Each  Noteholder will  also  have
certain rights to require the Company to purchase such Notes upon the occurrence
of a Change of Control. See "-- Change of Control" below.
 
    If  fewer than  all the  Notes are  to be  redeemed, selection  of Notes for
redemption will be made by the Trustee, on a pro rata basis or by lot or by  any
other  means the Trustee determines to be fair and appropriate and that complies
with applicable legal and securities exchange requirements.
 
                                       48
<PAGE>
    The provisions of the  New Credit Agreement  prohibit APS from  repurchasing
the  Notes pursuant to any of the redemption provisions described herein without
first obtaining the consent of the Banks.
 
MANDATORY SINKING FUND
 
    There are no mandatory sinking fund payments for the Notes.
 
CHANGE OF CONTROL
 
    Upon a Change of Control occurring at  any time, each Holder shall have  the
right  to require  that APS  purchase all or  part of  such Holder's  Notes at a
purchase price  in cash  equal to  101%  of the  principal amount  thereof  plus
accrued  and unpaid interest,  if any, to  the date of  purchase (subject to the
right of each Holder of record on  the relevant record date to receive  interest
due  on the  relevant interest  payment date)  (the "Change  of Control Purchase
Price"), in accordance  with the  terms contemplated  below; PROVIDED,  HOWEVER,
that notwithstanding a Change of Control, APS shall not be obligated to purchase
the  Notes pursuant  to this  covenant in  the event  that it  has exercised its
rights to  redeem  all  of the  Notes  as  described above  under  "--  Optional
Redemption."  In the event that at the time of such Change of Control, the terms
of the New Credit Agreement or other Senior Indebtedness of Holding, APS or  any
Restricted  Subsidiary Guarantor restrict or prohibit  the purchase of the Notes
pursuant to this provision, then prior to  the mailing of the notice to  Holders
provided  for  in the  next paragraph  below, but  in any  event within  30 days
following any  Change of  Control, Holding,  APS or  such Restricted  Subsidiary
Guarantor,  as applicable, shall (i) repay or cause to be repaid in full the New
Credit Agreement or such other Senior Indebtedness or offer to repay in full the
New Credit Agreement or such other Senior Indebtedness and repay or cause to  be
repaid the New Credit Agreement or such other Senior Indebtedness of each lender
who  has accepted  such offer  or (ii)  obtain the  requisite consent  under the
agreements governing the New Credit Agreement or such other Senior Indebtedness,
in each case in order to permit the purchase of the Notes as provided for below.
The provisions of  the New  Credit Agreement  prohibit APS  from purchasing  the
Notes  pursuant to this section. Although the requirement to purchase Notes upon
a Change of Control as  described in the next  paragraph is absolute whether  or
not  Holding,  APS  or  such  Restricted  Subsidiary  Guarantor,  as applicable,
complies with  the covenant  set forth  in the  second preceding  sentence,  and
failure  to  purchase  Notes would  constitute  an  Event of  Default  under the
Indenture, the terms  described above  in "--  Subordination of  Notes" and  "--
Subordination  of Note Guarantees; Release  of Restricted Subsidiary Guarantees"
may prevent payment of the Change of Control Purchase Price (whether at the date
of purchase  or  upon acceleration  of  the  Notes), depending  upon  the  funds
available  to APS at such  time. There can be no  assurance that Holding, APS or
such Restricted Subsidiary Guarantor, as  applicable, will be able, as  required
by  the  Indenture, to  repay  the New  Credit  Agreement or  such  other Senior
Indebtedness or obtain the necessary consents thereunder to permit the  purchase
of the Notes upon a Change of Control.
 
    Within  30 days following any  Change of Control (except  as provided in the
proviso to the first  sentence of the preceding  paragraph), APS shall send,  by
first-class mail to each Holder, a notice (with a copy to the Trustee) stating:
 
   
        (i)  that a  Change of  Control has occurred,  that such  Holder has the
    right to  require APS  to purchase  such  Holder's Notes  at the  Change  of
    Control  Purchase Price and that all  Notes timely tendered will be accepted
    for payment;
    
 
   
        (ii) the  circumstances  and relevant  facts  regarding such  Change  of
    Control, including, to the extent available, information with respect to pro
    forma  historical income,  cash flow  and capitalization,  each after giving
    effect to such Change of Control, events causing such Change of Control  and
    the date such Change of Control is deemed to have occurred;
    
 
   
       (iii)  the purchase date (which  shall be no earlier  than 30 days and no
    later than 60 days from the date such notice is mailed); and
    
 
                                       49
<PAGE>
   
       (iv)  the  instructions  and  relevant  information  determined  by  APS,
    consistent  with this  provision, that a  Holder must follow  or consider in
    order to have its Notes  purchased, together with the information  contained
    in the next paragraph (and including any related materials).
    
 
    Holders  electing to have a Note purchased will be required to surrender the
Note, with  an appropriate  form duly  completed,  to the  Paying Agent  at  the
address  specified  in the  notice  at least  five  Business Days  prior  to the
purchase date. Holders will be entitled to withdraw their election if the Paying
Agent receives not later than three Business Days prior to the purchase date,  a
facsimile  transmission  or letter  setting forth  the name  of the  Holder, the
principal amount of the Note that was delivered for purchase by the Holder and a
statement that such Holder  is withdrawing such Holder's  election to have  such
Note purchased.
 
    On  the purchase date, all Notes purchased by APS under this provision shall
be delivered to the Trustee  for cancellation, and APS  shall pay the Change  of
Control Purchase Price to the Holders entitled thereto.
 
    APS shall comply, to the extent applicable, with the requirements of Section
14(e)  of  the Exchange  Act and  any  other securities  laws or  regulations in
connection with  the repurchase  of Notes  pursuant to  this provision.  To  the
extent  that the provisions of any  securities laws or regulations conflict with
this provision,  APS  shall  comply  with the  applicable  securities  laws  and
regulations  and shall not be deemed to have breached its obligations under this
provision by virtue thereof.
 
    The occurrence of certain  of the events that  would constitute a Change  of
Control  could constitute  a default  under the  New Credit  Agreement and might
constitute  a  default  under  future  Indebtedness  of  APS,  Holding  and  the
Restricted  Subsidiary Guarantors. In  addition, the exercise  by the Holders of
the Notes of their right  to require APS to repurchase  the Notes could cause  a
default  under such Indebtedness even if the  Change of Control itself does not,
due to the financial effect of such  repurchase on APS. Finally, if a Change  of
Control  Offer is made, there can be  no assurance that APS will have sufficient
funds or other resources to pay the Change of Control Purchase Price for all the
Notes that  might be  delivered by  Holders thereof  seeking to  require APS  to
purchase Notes. See "Risk Factors -- Leverage; Restrictive Covenants."
 
    The  conveyance, transfer or lease of  all or substantially all of Holding's
assets, among other things, may constitute a Change of Control. The Indenture is
governed by New York  law, and there is  no established quantitative  definition
under  New  York law  of "substantially  all"  of the  assets of  a corporation.
Accordingly, if Holding or APS were to  dispose of less than all of its  assets,
it might be unclear whether a Change of Control has occurred and whether APS may
be  required to make a Change of  Control Offer. In any particular transfer, the
determination as to whether a Change of Control has occurred will depend on  the
percentage  of  operating  assets  and  total  assets  transferred,  among other
measurements, and the other facts and circumstances of the transaction and  will
be  made by APS, and  APS shall give notice  to the Holders of  the Notes of the
occurrence of a Change of Control.
 
    APS's obligations  to repurchase  the Notes  upon a  Change of  Control  are
guaranteed  on a  senior subordinated basis  by Holding pursuant  to the Holding
Guarantee and  by the  other Restricted  Subsidiary Guarantors  pursuant to  the
Restricted  Subsidiary  Guarantees.  Such Note  Guarantees  are  subordinated to
Senior Indebtedness of Holding or such Restricted Subsidiaries, as the case  may
be,  to the same  extent described above under  "-- Subordination of Guarantees;
Release of Restricted Subsidiary Guarantees."
 
CERTAIN COVENANTS
 
    The Indenture contains covenants, including, among others, the following:
 
    LIMITATION ON INDEBTEDNESS.   Holding shall  not, and shall  not permit  any
Restricted  Subsidiary  to,  Incur  any  Indebtedness;  PROVIDED,  HOWEVER, that
Holding or any Restricted Subsidiary may Incur
 
                                       50
<PAGE>
Indebtedness if on  the date  thereof the Consolidated  Interest Coverage  Ratio
would, after giving pro forma effect to such proposed Incurrence and the receipt
and application of the proceeds thereof, be greater than 2.25:1.00.
 
    Notwithstanding   the  foregoing  limitation,  Holding  and  its  Restricted
Subsidiaries may Incur  the following Indebtedness:  (i) Indebtedness under  the
New  Credit Agreement of (a) up to $65 million in term loan borrowings (less the
amount of any permanent  reductions in such borrowings  thereunder) and (b)  the
greater  of (x) $235 million in revolving  credit borrowings (less the amount of
any permanent  repayments of  principal  or other  permanent reductions  in  the
amount  of available borrowings thereunder)  and (y) the sum  of 90% of the book
value of the  accounts receivable  of Holding and  its Restricted  Subsidiaries,
which  do not  constitute Receivables  Collateral for  any Qualified Receivables
Transaction, and 60%  of the  book value  of the  inventory of  Holding and  its
Restricted Subsidiaries, in each case calculated in accordance with GAAP and net
of any reserves established or required under GAAP; (ii) Indebtedness of Holding
owing to and held by any Wholly Owned Restricted Subsidiary or Indebtedness of a
Restricted  Subsidiary  owing  to  and  held  by  Holding  or  any  Wholly Owned
Restricted Subsidiary;  PROVIDED,  HOWEVER,  that  any  subsequent  issuance  or
transfer  of any Capital Stock that results  in any such Wholly Owned Restricted
Subsidiary ceasing to be a Wholly Owned Restricted Subsidiary or any  subsequent
transfer  of  any  such  Indebtedness  (except  to  Holding  or  a  Wholly Owned
Restricted Subsidiary)  shall  be  deemed,  in  each  case,  to  constitute  the
Incurrence  of  such  Indebtedness  by the  issuer  thereof;  (iii) Indebtedness
represented by the Notes,  the Holding Guarantee  and the Restricted  Subsidiary
Guarantees,  and  any Indebtedness  (other  than the  Indebtedness  described in
clauses (i) or  (ii) above)  outstanding on  the Issue  Date; (iv)  Indebtedness
under any Interest Rate Agreement or Currency Agreement; PROVIDED, HOWEVER, that
the  obligations created  by (a)  any such  Interest Rate  Agreement or Currency
Agreement are related to payment obligations on Indebtedness otherwise permitted
under the Indenture or  (b) any such Currency  Agreement is designed to  protect
Holding and its Restricted Subsidiaries against fluctuations in foreign currency
exchange  rates and  does not  increase Indebtedness  of Holding  or any  of its
Restricted Subsidiaries except to the extent  of any such fluctuations, and,  in
each  case,  such  Interest Rate  Agreement  or  Currency Agreement  is  not for
speculative purposes; (v) Indebtedness  in connection with  one or more  standby
letter of credit reimbursement obligations with respect to lease obligations and
loans to jobbers issued in the ordinary course of business, including letters of
credit  of  PI or  an Affiliate  of PI  assumed  by APS  in connection  with the
Acquisition, in an  aggregate face  amount at  any one  time not  to exceed  $10
million; (vi) Indebtedness in connection with one or more commercial documentary
letters  of credit or bankers' acceptances issued  for the account of Holding or
any Restricted Subsidiary for the purchase of goods and services in the ordinary
course of  business;  (vii)  Refinancing Indebtedness  Incurred  in  respect  of
Indebtedness  Incurred pursuant to  the provisions of  the immediately preceding
paragraph or clause (iii)  or (xvii) of this  paragraph; (viii) Indebtedness  of
Holding or any Restricted Subsidiary arising from the honoring of a check, draft
or  similar  instrument drawn  against  insufficient funds,  PROVIDED  that such
Indebtedness  is  extinguished  within  three  days  of  its  Incurrence;   (ix)
non-interest  bearing Indebtedness  pursuant to  a promissory  note that  may be
issued by APS  to GKN Parts  (or its assignee)  of up to  $3 million related  to
purchase  price adjustments pursuant to the Purchase Agreement; (x) Indebtedness
of APS or  any Restricted  Subsidiary consisting of  Guarantees, indemnities  or
other  obligations, in  each case in  respect of purchase  price adjustments, in
connection with the  acquisition or  disposition of assets  permitted under  the
Indenture;  (xi) Guarantees of up to $5  million in the aggregate outstanding at
any time  under a  Qualified Receivables  Transaction; (xii)  Indebtedness of  a
Receivables  Subsidiary in respect of any Qualified Receivables Transaction that
at all times  enables such Receivables  Subsidiary to qualify  as a  Receivables
Subsidiary;  (xiii)  Indebtedness  under  Inventory  and  Merchandise Repurchase
Agreements; (xiv)  Guarantees of  up to  an aggregate  principal amount  of  $10
million  at  any one  time outstanding  of  Indebtedness Incurred  by Management
Investors in connection with any  Management Subscription Agreement or  Incurred
by  management  employees  in  respect  of  relocation  loans  extended  to such
employees, and  any refinancings,  refundings, extensions  or renewals  thereof;
(xv)  Indebtedness of Holding or any of  its Restricted Subsidiaries of up to an
aggregate   principal    amount   of    $10   million    at   any    one    time
 
                                       51
<PAGE>
outstanding  Incurred  to  finance  the purchase  price  of  any  acquisition of
Additional Assets  other  than  from Holding  or  its  Restricted  Subsidiaries,
PROVIDED  that if such Indebtedness  is owed to a  Person, other than the Person
from whom such acquisition is made  or any Affiliate thereof, such  Indebtedness
shall  not exceed  60% of  the purchase price  of such  Additional Assets; (xvi)
Guarantees in connection with  sales or other  dispositions permitted under  the
Indenture,   including   Guarantees   with   respect   to   indemnification  and
then-existing lease obligations; (xvii) Indebtedness of a Restricted  Subsidiary
Incurred  and  outstanding on  or prior  to  the date  on which  such Restricted
Subsidiary was acquired by Holding  or a Restricted Subsidiary and  Indebtedness
of a Person assumed by Holding or a Restricted Subsidiary in connection with the
acquisition  of assets from such  Person, PROVIDED that at  the time such assets
were owned by  such other Person  such Indebtedness was  either secured by  such
assets  or related  to the  acquisition, ownership,  improvement or  use of such
assets by such other Person (in  each case, other than Indebtedness Incurred  as
consideration  in, in contemplation of, or to  provide all or any portion of the
funds or credit  support utilized to  consummate, the transaction  or series  of
related  transactions  pursuant to  which  such Restricted  Subsidiary  became a
Restricted Subsidiary or such  assets were acquired by  Holding or a  Restricted
Subsidiary,  as applicable); PROVIDED, HOWEVER, that at the time such Restricted
Subsidiary is acquired by Holding or a Restricted Subsidiary or such assets  are
acquired  by Holding or a Restricted  Subsidiary, as applicable, Holding and its
Restricted Subsidiaries  would  have been  able  to Incur  $1.00  of  additional
Indebtedness  pursuant to  the preceding  paragraph after  giving effect  to the
Incurrence  of  such  Indebtedness  pursuant  to  this  clause  (xvii);  (xviii)
Indebtedness  in respect of judgment, appeal, surety, performance and other like
bonds provided by Holding or any of its Restricted Subsidiaries in the  ordinary
course  of  business; (xix)  Indebtedness of  Holding or  any of  its Restricted

course  of  business, or  representing  obligations in  respect  of deductibles,

compensation  and other  insurance coverage Incurred  in the  ordinary course of
business or reimbursement obligations in respect of amounts Incurred or paid  by
an  insurance company under any insurance program in effect on the Issue Date or
instituted after  the  Issue Date  in  the  ordinary course  of  business;  (xx)

(iv)  make any Investment other  than a Permitted Investment  in any Person (any

Payment")  if at the time of and after giving effect to such Restricted Payment:
(a) a Default or an  Event of Default shall have  occurred and be continuing  or

proceeds  of  the issuance  or  sale of  Capital  Stock to  Management Investors
exceeds the aggregate repurchases of Capital Stock made pursuant to subparagraph
(xiii) of the  definition of "Permitted  Investments" shall be  included in  the
calculation  of  the Net  Cash  Proceeds under  this  clause (2)),  including an
issuance or sale upon conversion of Indebtedness convertible into Capital  Stock
of  Holding  (other than  Redeemable Stock)  and from  the exercise  of options,
warrants  or  rights  to  purchase  Capital  Stock  of  Holding  (but  excluding
Redeemable  Stock); (3)  the amount  equal to  the net  reduction in Investments
resulting from (A)  payments of dividends,  repayments of loans  or advances  or
other  transfers of assets  to Holding or  any Restricted Subsidiary  or (B) the
redesignation of Unrestricted Subsidiaries as Restricted Subsidiaries (valued in
each case  as provided  in the  definition of  "Investment") not  to exceed  the
amount  of  any such  Investment previously  made by  Holding or  any Restricted
Subsidiary, which amount was  treated as a Restricted  Payment, in each case  to
the  extent not  included in Consolidated  Net Income; (4)  the amount (accreted
value in the case of Indebtedness issued with original issue discount) by  which
Senior   Indebtedness,   Senior   Subordinated   Indebtedness   or  Subordinated

subsequent to the Issue Date, of such Indebtedness for Capital Stock (other than
Redeemable Stock) of  Holding (less  the amount of  any cash  or other  property
distributed  by Holding, APS  or such Restricted  Subsidiary Guarantor upon such
conversion or exchange); and (5) $15 million.
 
    The provisions  of this  section shall  not prohibit:  (i) any  purchase  or
redemption  of  Capital Stock  of Holding  or  Subordinated Obligations  made by
exchange for, or out  of the proceeds of  the substantially concurrent sale  of,
Capital  Stock of  Holding (other than  Redeemable Stock and  other than Capital
Stock issued or  sold to a  Subsidiary or  an employee stock  ownership plan  or

Restricted Payments;  (iii) dividends  paid within  60 days  after the  date  of
declaration  thereof if  at such  date of  declaration such  dividend would have
complied with the preceding  paragraph; PROVIDED, HOWEVER, that  at the time  of
payment of such dividend, no other Default shall have occurred and be continuing
(or  result therefrom); PROVIDED  FURTHER, HOWEVER, that  such dividend shall be
included in the calculation of the amount of Restricted Payments from and  after
the  date of  declaration of  such dividends;  or (iv)  the repurchase  of Notes
pursuant to the covenant described under "-- Change of Control" above; PROVIDED,
HOWEVER, that  such repurchases  will  be excluded  in  the calculation  of  the
amounts of Restricted Payments.
 
    LIMITATION    ON    RESTRICTIONS    ON    DISTRIBUTIONS    FROM   RESTRICTED
SUBSIDIARIES.  Holding shall not, and shall not permit any Restricted Subsidiary
to, create  or  otherwise cause  or  permit to  exist  or become  effective  any
consensual   encumbrance  or  restriction  on  the  ability  of  any  Restricted
Subsidiary to
 
                                       53

Restricted Subsidiary or  (2) of  a Person assumed  by Holding  or a  Restricted
Subsidiary  in  connection  with the  acquisition  of assets  from  such Person,
PROVIDED that at  the time  such assets  were owned  by such  other Person  such
Indebtedness  was either secured  by such assets or  related to the acquisition,
ownership, improvement  or  use  of  such  assets  (in  each  case,  other  than
Indebtedness  Incurred as consideration  in, in contemplation  of, or to provide
all or any portion of  the funds or credit  support utilized to consummate,  the
transaction  or series of related transactions pursuant to which such Restricted
Subsidiary became  a  Restricted Subsidiary  or  such assets  were  acquired  by
Holding or a Restricted Subsidiary, as applicable) and outstanding on such date;
(c)  any  encumbrance  or  restriction  pursuant  to  an  agreement  effecting a
refinancing of Indebtedness  Incurred pursuant  to an agreement  referred to  in
clause  (a)  or  (b) of  this  provision or  contained  in any  amendment  to an
agreement referred to in clause (a) or (b) of this provision; PROVIDED, HOWEVER,
that the  encumbrances  and  restrictions  contained  in  any  such  refinancing
agreement or amendment are not materially less favorable to the Noteholders than
encumbrances  and restrictions contained in such  agreements; (d) in the case of
clause (iii), any encumbrance or restriction  (1) that restricts in a  customary
manner the subletting, assignment or transfer of any property or asset that is a
lease, license, conveyance or contract or similar property or asset, (2) arising
by  virtue  of any  transfer of,  agreement  to transfer,  option or  right with
respect to, or  Lien on, any  property or  assets of Holding  or any  Restricted
Subsidiary  not otherwise prohibited by the  Indenture, or (3) arising or agreed
to in the ordinary course of business and that does not, individually or in  the
aggregate,  detract  from the  value of  property  or assets  of Holding  or any
Restricted Subsidiary, in each  case in any manner  material to Holding or  such
Restricted  Subsidiary;  (e)  any  encumbrance  or  restriction  pursuant  to an
agreement relating to an acquisition of property, so long as such encumbrance or
restriction relates solely to the property so acquired; (f) any encumbrances  or
restrictions  pursuant to the New Credit  Agreement so long as such encumbrances
or restrictions permit the payment of interest on, and principal of, the  Notes,
except  as otherwise provided above under "  -- Subordination of Notes" and " --
Subordination of Note Guarantees; Release of Restricted Subsidiary  Guarantees;"
(g)  any restriction with respect to a Restricted Subsidiary imposed pursuant to

    LIMITATION ON  SALES OF  ASSETS AND  RESTRICTED SUBSIDIARY  STOCK.   Holding
shall  not, and shall  not permit any  Restricted Subsidiary to,  make any Asset
Disposition unless (i) Holding  or such Restricted Subsidiary,  as the case  may
be,  receives consideration substantially concurrent with such Asset Disposition
at least equal  to the Fair  Market Value, as  determined in good  faith by  the
Board  of Directors, the  determination of which  shall be evidenced  by a Board
Resolution (including as  to the value  of all non-cash  consideration), of  the
shares  and assets subject to  such Asset Disposition; (ii)  at least 75% of the
consideration thereof received by  Holding or such  Restricted Subsidiary is  in
the form of (a)(x) cash or Temporary Cash Investments or (y) Senior Indebtedness
of  APS, Holding or any Restricted  Subsidiary Guarantor assumed by a transferee
(in respect of which  APS, Holding or such  Restricted Subsidiary Guarantor,  as
the  case  may be,  has no  further  obligations), which  assumption permanently
reduces the amount of Indebtedness permitted pursuant to clause (i)(a) or clause
(xxi) of  "  --  Limitation  on Indebtedness;"  plus  (b)  other  consideration;
PROVIDED,  HOWEVER,  that  the  aggregate  amount  of  such  other consideration
received by Holding and  its Restricted Subsidiaries from  the Issue Date  shall
not  exceed $10 million plus the cash  proceeds realized from the disposition of
any such
 
                                       54
<PAGE>
other consideration, which  cash proceeds  shall be applied  in accordance  with
this covenant; and PROVIDED, FURTHER, that any consideration received by Holding
or  any Restricted Subsidiary pursuant to any disposition by Holding or any such
Restricted Subsidiary of any  property, stock or assets  of AFCO at Fair  Market
Value  shall  not be  subject  to this  clause (ii);  and  (iii) APS  or Holding
delivers an  Officers' Certificate  to the  Trustee certifying  that such  Asset
Disposition complies with clauses (i) and (ii) (if applicable).
 
    Net  Available  Cash  (or  any portion  thereof)  from  any  permitted Asset
Disposition may be  applied by Holding  (or such Restricted  Subsidiary, as  the
case  may be) within 365 days from the receipt of such Net Available Cash (a) to
prepay, repay or purchase Senior Indebtedness of Holding, Senior Indebtedness of
APS or Senior Indebtedness of a  Restricted Subsidiary Guarantor (in each  case,
other  than Indebtedness  owed to  Holding or an  Affiliate of  Holding); (b) to
reinvest in Additional Assets (including by means of an Investment in Additional
Assets by a Restricted Subsidiary with Net Available Cash received by Holding or
another  Restricted  Subsidiary)  and/or  (c)  to  purchase  and  retire  Notes;
PROVIDED, HOWEVER, that in connection with any prepayment, repayment or purchase
of  Indebtedness  pursuant to  clause (a)  or  (c) above,  Holding, APS  or such
Restricted Subsidiary Guarantor shall retire  such Indebtedness and shall  cause
the  related loan  commitment (if  any) to be  permanently reduced  in an amount
equal to the principal amount so prepaid, repaid or purchased. Any Net Available
Cash that is not applied by Holding or its Restricted Subsidiaries in the manner
and in  the relevant  time period  described in  the preceding  sentence  shall,
immediately  upon expiration  of such  time period, become  and be  added to any
then-existing "Excess Proceeds." Holding and its Restricted Subsidiaries may use
Net Available  Cash to  repay  borrowings under  the Revolving  Credit  Facility
(without   permanent  reduction  in   available  borrowing  thereunder)  pending
application in accordance with  this paragraph and prior  to such Net  Available
Cash  becoming Excess  Proceeds. When  the aggregate  amount of  Excess Proceeds
(together with income  earned thereon)  exceeds $5  million, APS  shall make  an
offer  (an "Excess Proceeds Offer") to purchase Notes pursuant to and subject to
the conditions of the following paragraph. Pending application of Net  Available
Cash  pursuant  to the  preceding  sentence, such  Net  Available Cash  shall be
invested in Temporary Cash Investments.
 
    In the event APS is required to make an Excess Proceeds Offer, it will  make
an  offer in accordance with  the procedures set forth  in the next paragraph to
purchase from all Holders on a pro rata  basis the Notes at a purchase price  in
cash  of 100% of their principal amount  plus accrued and unpaid interest to the
date of purchase (subject to the right of each Holder of record on the  relevant
record  date to receive interest due on  the relevant interest payment date) and
shall purchase from  Holders accepting  such Excess Proceeds  Offer the  maximum
principal amount of Notes that may be purchased from funds in an amount equal to
all  then-existing Excess Proceeds. Upon completion  of an Excess Proceeds Offer
(including payment of  the purchase price  for Notes duly  tendered) the  Excess
Proceeds  that were the subject of such  offer shall cease to be Excess Proceeds
and APS may use the remaining Excess Proceeds in its general operations.
 
    Promptly, and in  any event within  30 days after  APS becomes obligated  to
make  an Excess Proceeds Offer, APS shall be obligated to deliver to the Trustee
and send, by first-class mail to each Holder, a written notice stating that  the
Holder may elect to have such Holder's Notes purchased by APS either in whole or
in  part  subject to  proration  in integral  multiples  of $1,000  of principal
amount, at the applicable  purchase price. The notice  shall specify a  purchase
date  not less than 30 days  or more than 60 days  after the date of such notice
(the "Excess Proceeds Purchase Date")  and shall contain information  concerning
the  Excess Proceeds Offer (including, to  the extent available, appropriate pro
forma financial information)  and all  instructions and  materials necessary  to
tender   Notes  pursuant  to  the  Excess  Proceeds  Offer,  together  with  the
information contained in the next following paragraph.
 
    Not later than  the date  upon which written  notice of  an Excess  Proceeds
Offer  is delivered to the  Trustee as provided above,  APS shall deliver to the
Trustee an Officers'  Certificate as to  (i) the amount  of the Excess  Proceeds
Offer  (the  "Excess Proceeds  Offer Amount"),  (ii) the  allocation of  the Net
Available Cash from the Asset Disposition pursuant to which such Excess Proceeds
Offer is  being  made and  (iii)  the compliance  of  such allocation  with  the
provisions of the next preceding paragraph.
 
                                       55
<PAGE>
On  such date, APS shall  also deposit irrevocably with  the Trustee or with the
Paying Agent (or,  if Holding or  any of  its Subsidiaries is  acting as  Paying
Agent,  Holding shall, or shall  cause its Subsidiary to,  segregate and hold in
trust) in  cash or  Temporary Cash  Investments an  amount equal  to the  Excess
Proceeds  Offer Amount to be held for  payment in accordance with the provisions
of this provision. On the Excess  Proceeds Purchase Date, APS shall deliver,  or
cause  to be delivered, to  the Trustee the Notes  or portions thereof that have
been tendered properly to and are to be accepted by APS. The Paying Agent  shall
promptly  mail or deliver payment to each  tendering Holder in the amount of the
purchase price. In  the event  that the aggregate  purchase price  of the  Notes
delivered  to the  Trustee is  less than the  Excess Proceeds  Offer Amount, the
excess shall be  delivered to  APS immediately  after expiration  of the  Excess
Proceeds Offer Period.
 
    A Holder electing to have a Note purchased will be required to surrender the
Note,  with  an appropriate  form duly  completed,  to the  Paying Agent  at the
address specified in the notice at least five Business Days prior to the  Excess
Proceeds  Purchase Date. A Holder  will be entitled to  withdraw his election if
the Paying Agent receives not later than three Business Days prior to the Excess
Proceeds Purchase Date,  a facsimile  transmission or letter  setting forth  the
name  of the  Holder, the principal  amount of  the Note that  was delivered for
purchase by  the Holder  and a  statement that  such Holder  is withdrawing  his
election  to have such Note purchased. If  the aggregate purchase price of Notes
surrendered by Holders  exceeds the  Excess Proceeds Offer  Amount, the  Trustee
shall  select  the  Notes  to  be  purchased on  a  pro  rata  basis  (with such
adjustments as may be deemed  appropriate by the Trustee  so that only Notes  in
denominations  of  $1,000 or  integral multiples  thereof, shall  be purchased).
Holders whose Notes are purchased only in part will be issued new Notes equal in
principal amount to the unpurchased portion of the Notes surrendered.
 
    At the time APS delivers,  or causes to be  delivered, Notes to the  Trustee
that  are  to be  accepted  for purchase,  APS  will also  deliver  an Officers'
Certificate stating that such Notes are to be accepted by APS pursuant to and in
accordance with the terms of this provision. A Note shall be deemed to have been
accepted for purchase  at the time  the Paying Agent  mails or delivers  payment
therefor to the surrendering Holder.
 
    APS shall comply, to the extent applicable, with the requirements of Section
14(e)  of  the Exchange  Act and  any  other securities  laws or  regulations in
connection with  the repurchase  of Notes  pursuant to  this provision.  To  the
extent  that the provisions of any  securities laws or regulations conflict with
this provision,  APS  shall  comply  with the  applicable  securities  laws  and
regulations  and shall not be deemed to have breached its obligations under this
provision by virtue thereof.
 
    LIMITATION ON  TRANSACTIONS WITH  AFFILIATES.   (a) Holding  shall not,  and
shall  not permit any Restricted Subsidiary  to, directly or indirectly, conduct
any business,  enter  into or  permit  to exist  any  transaction or  series  of
transactions  (including the  purchase, conveyance, disposition,  sale, lease or
exchange of any property or the rendering of any service) with any Affiliate  of
Holding  (an  "Affiliate  Transaction")  unless  the  terms  of  such  Affiliate
Transaction are (i) as  favorable to Holding or  such Restricted Subsidiary,  as
the case may be, as those that could be obtained at the time of such transaction
for a similar transaction in arm's-length dealings with a Person who is not such
an  Affiliate  and  (ii)  with respect  to  an  Affiliate  Transaction involving
aggregate payments  or value  of $5.0  million  or greater,  a majority  of  the
Independent  Directors have determined in good faith that the criteria set forth
in  clause  (i)  are  satisfied   and  have  approved  the  relevant   Affiliate
Transaction,  such approval to  be evidenced by  a Board Resolution,  or, in the
event there are no such Independent Directors, a fairness opinion is provided by
a nationally recognized  appraisal or  investment banking firm  with respect  to
such Affiliate Transaction.
 
                                       56
<PAGE>
    (b)  The provisions  of the preceding  paragraph shall not  prohibit (i) any
Restricted Payment permitted to be paid pursuant to "-- Limitation on Restricted
Payments" above or any Indebtedness to  be Incurred pursuant to clause (xiv)  of
the  second  paragraph  of  the  covenant  described  under  "--  Limitation  on
Indebtedness," or  any  payments  in  respect  thereof,  (ii)  any  issuance  of
securities, or other payments, awards or grants in cash, securities or otherwise

ownership  plans approved by the  Board of Directors of  Holding, (iii) loans or
advances to employees in  the ordinary course of  business, (iv) the payment  of
reasonable  fees to directors of Holding and its Restricted Subsidiaries who are

advisory  and similar services  provided to Holding  and its Subsidiaries; (vii)
any transaction with an officer  or member of the Board  of Directors of APS  or
Holding  not covered by clause (ii) or  (iii) above entered into in the ordinary
course  of  business  involving  compensation,  indemnity  or  employee  benefit
arrangements;  or  (viii)  any  transaction  arising  out  of  agreements  as in
existence on the Issue Date, including, without limitation, the  Indemnification
Agreement referred to under "Certain Relationships and Related Transactions" and
any payments made pursuant thereto.
 
    LIMITATION ON LAYERED INDEBTEDNESS.  Holding shall not, and shall not permit
any  Restricted Subsidiary  to, directly  or indirectly,  Incur any Indebtedness
that is subordinate in right of  payment to any other Indebtedness, unless  such
Indebtedness  is subordinate in right  of payment to, or  ranks PARI PASSU with,
the Holding Guarantee, in the case of Holding, the Notes, in the case of APS, or
the relevant  Restricted  Subsidiary Guarantee,  in  the case  of  a  Restricted
Subsidiary Guarantor.
 
    LIMITATION  ON SUBORDINATED LIENS.  Holding  shall not, and shall not permit
any Restricted Subsidiary to, directly or indirectly, create or permit to  exist

Holding, in the case of Holding, of APS, in the case of APS, or of a  Restricted
Subsidiary  Guarantor, in the  case of a Restricted  Subsidiary Guarantor) on or
with respect to any of its property or assets (including Capital Stock), whether
owned on  the  Issue Date  or  thereafter acquired,  or  any income  or  profits
therefrom  securing any obligation  unless contemporaneously therewith effective
provision is made to secure the Holding  Guarantee, in the case of Holding,  the
Notes,  in the case of APS, or  the relevant Restricted Subsidiary Guarantee, in
the case of any  Restricted Subsidiary Guarantor, equally  and ratably with  (or
prior to) such obligation for so long as such obligation is so secured.
 
    LIMITATION ON OWNERSHIP OF CAPITAL STOCK OF RESTRICTED
SUBSIDIARIES.   Holding shall not (a)  permit any Restricted Subsidiary to issue
any Capital Stock other than  to Holding or one  of its Wholly Owned  Restricted
Subsidiaries  or (b) permit any  Person (other than Holding  or any Wholly Owned
Restricted Subsidiary) to  own any  Capital Stock of  any Restricted  Subsidiary
(other than directors' qualifying shares), except, in each case, (x) as a result
of  the sale of  up to 49% of  the shares of a  Restricted Subsidiary other than

Person,   unless:  (i)  the  resulting,  surviving  or  transferee  Person  (the
"Successor Company") shall  be a  corporation organized and  existing under  the
laws  of the  United States  of America,  any State  thereof or  the District of
Columbia, and the Successor Company (if not Holding or APS, as the case may  be)

that all conditions precedent relating to such transaction have been met.
 
    The Successor Company  shall succeed  to, and  be substituted  for, and  may
exercise every right and power of, Holding or APS, as the case may be, under the
Indenture,  but the  predecessor Company  in the  case of  a lease  shall not be
released from the obligation to pay the principal of and interest on the Notes.
 
    Notwithstanding the foregoing, Holding and  APS may consolidate with,  merge
into  or transfer all or part of its  properties and assets to each other or any
other Wholly Owned Restricted Subsidiary.
 
    Holding shall not permit any Restricted Subsidiary Guarantor to  consolidate
with  or merge with or into (whether or not such Restricted Subsidiary Guarantor
is the surviving Person)  another Person other than  Holding, APS or any  Wholly
Owned  Restricted Subsidiary or in a  transaction involving an Asset Disposition
carried out  pursuant  to  and  in accordance  with  "--  Certain  Covenants  --
Limitation on Sales of Assets and Restricted Subsidiary Stock" above unless: (i)
the  Person  formed  by  or  surviving any  such  consolidation  or  merger (the
"Successor Guarantor"),  if other  than  such Restricted  Subsidiary  Guarantor,
assumes  all  obligations  of  such Restricted  Subsidiary  Guarantor  under the
relevant Restricted  Subsidiary  Guarantee  and  the  Indenture  pursuant  to  a
supplemental  indenture  as required  in the  Indenture; (ii)  immediately after
giving effect to  such transaction,  such Successor  Guarantor is  or becomes  a
Restricted Subsidiary; (iii) immediately after giving effect to such transaction
on  a pro forma basis (and treating  any Indebtedness that becomes an obligation
of the Successor  Guarantor or  any Restricted Subsidiary  as a  result of  such
transaction  as  having  been  Incurred  by  the  Successor  Guarantor  or  such
Restricted Subsidiary at the time of such transaction), (a) no Default or  Event
of  Default  shall have  occurred  and be  continuing  and (b)  Holding  and its
Restricted Subsidiaries (including  the Successor Guarantor  and its  Restricted
Subsidiaries)  would be  able to  Incur an  additional $1.00  of Indebtedness in
compliance with the Consolidated Interest  Coverage Ratio limitations set  forth
in  the first paragraph of "-- Certain Covenants -- Limitation on Indebtedness;"
and (iv)  the  Trustee receives  an  Officers'  Certificate and  an  Opinion  of
Counsel,  each  stating  that such  consolidation  or merger  complies  with the
Indenture and that all  conditions precedent relating  to such transaction  have
been met.
 
EVENTS OF DEFAULT AND REMEDIES
    An  "Event of Default" will occur under the Indenture in the event of: (i) a
default in any payment  of interest on  any Note when the  same becomes due  and
payable, whether or not such payments shall
 
                                       58

Subordination  of Notes"  or "--  Subordination of  Note Guarantees;  Release of
Restricted Subsidiary Guarantees" or (b) a  failure to redeem or purchase  Notes
when  required  pursuant to  the Indenture  or  the Notes,  whether or  not such

Guarantees";  (iii)  a failure  to  comply with  the  provisions of  "-- Merger,

and Restricted Subsidiary Stock," "--  Limitation on Layered Indebtedness,"  "--
Limitation   on  Subordinated  Liens,"  "--   Limitation  on  Transactions  with
Affiliates" or  "--  Limitation on  Ownership  of Capital  Stock  of  Restricted
Subsidiaries"  in "-- Certain Covenants" (other than a failure to purchase Notes
when required  under  "--  Change  of  Control"  or  "--  Certain  Covenants  --
Limitation  on Sale of Assets and Restricted  Subsidiary Stock") or a failure to
cause a Restricted  Subsidiary, upon  its becoming a  Restricted Subsidiary,  to
enter  into  a  supplemental  indenture providing  for  a  Restricted Subsidiary
Guarantee as required in the Indenture,  and such failure continues for 30  days
after  the notice  specified below  or APS  fails to  give the  notice specified
below; (v) a failure to  comply with any of the  agreements in the Notes or  the
Indenture  (other than those referred to in (i), (ii), (iii) or (iv) above), and
such failure continues for 60 days after the notice specified below or APS fails
to give the notice specified below;  (vi) the principal, any premium or  accrued
and  unpaid interest of Indebtedness of  Holding or any Restricted Subsidiary is
not paid  within  any  applicable  grace  period  after  final  maturity  or  is
accelerated by the holders thereof because of a default, and the total amount of
such  Indebtedness unpaid or accelerated exceeds $7.5 million at the time; (vii)
Holding or any Restricted  Subsidiary pursuant to or  within the meaning of  any
Bankruptcy  Law: (a) commences a voluntary case; (b) consents to the entry of an

appointment  of a Custodian of  it or for any  substantial part of its property;
(d) makes a general assignment  for the benefit of  its creditors; or (e)  takes

the  payment of money in  excess of $7.5 million at  the time is entered against
Holding or any  Restricted Subsidiary and  is not discharged  and either (a)  an
enforcement  proceeding has been commenced by any creditor upon such judgment or
decree or (b) there is a period of 60 days following the entry of such  judgment
or  decree during which such judgment or decree is not discharged, waived or the
execution thereof stayed and, in the case of (a) or (b), such default  continues
for 10 days.
 
    The  foregoing will constitute Events of Default whatever the reason for any
such Event of Default and whether it is voluntary or involuntary or is  effected
by operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body.
 
    A  Default under  clause (iv) or  (v) is not  an Event of  Default until the
Trustee or the Holders of at least  25% in principal amount of the Notes  notify
APS of the Default and Holding or APS does not cure such Default within the time
specified  (if any) after receipt  of such notice. Such  notice must specify the
Default, demand that it be remedied and  state that such notice is a "Notice  of
Default."
 
                                       59
<PAGE>
    APS  shall  deliver to  the  Trustee, within  30  days after  the occurrence
thereof, written notice  in the form  of an Officers'  Certificate of any  event
that  with the giving of notice  and the lapse of time  would become an Event of
Default, its status and  what action APS, Holding  or any Restricted  Subsidiary
Guarantor is taking or proposes to take with respect thereto.
 
    If  an Event of Default (other than an Event of Default specified in clauses
(vii) or (viii) above) occurs and is  continuing, the Trustee by notice to  APS,
or the Holders of at least 25% in principal amount of the Notes by notice to APS
and  the Trustee, may declare  the principal of and  accrued interest on all the
Notes to  be  due and  payable.  Upon such  a  declaration, such  principal  and
interest  shall be due and payable immediately. If an Event of Default specified
in clause (vii) or (viii) above occurs, the principal of and interest on all the
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 Noteholders. The
Holders of a majority in principal amount of the Notes by notice to the  Trustee
may  rescind any such acceleration and  its consequences if the rescission would
not conflict with any judgment or decree  and if all existing Events of  Default
have  been cured or waived  except nonpayment of principal  or interest that has
become due solely because of acceleration.  No such rescission shall affect  any
subsequent Default or impair any right consequent thereto.
 
    A  Noteholder may not pursue any remedy with respect to the Indenture or the
Notes unless: (i) the Holder gives to the Trustee written notice stating that an
Event of Default is continuing;  (ii) the Holders of  at least 25% in  principal
amount  of the Notes make a written request to the Trustee to pursue the remedy;
(iii) such  Holder  or Holders  offer  to  the Trustee  reasonable  security  or
indemnity  against any  loss, liability  or expense;  (iv) the  Trustee does not
comply with the  request within 60  days after  receipt of the  request and  the
offer  of security or indemnity; and (v)  the Holders of a majority in principal
amount of the Notes do  not give the Trustee  a direction inconsistent with  the
request during such 60-day period.
 
    A  Noteholder may not use  the Indenture to prejudice  the rights of another
Noteholder or to obtain a preference or priority over another Noteholder.
 
AMENDMENT, SUPPLEMENT AND WAIVER
 
    Subject to  certain  exceptions,  the  Indenture,  the  Notes,  the  Holding
Guarantee or the Restricted Subsidiary Guarantees may be amended or supplemented
by  APS, Holding, the  relevant Restricted Subsidiary  Guarantor and the Trustee
with the consent of the  Holders of at least a  majority in principal amount  of
such then outstanding Notes. Without notice to or the consent of any Noteholder,
APS, Holding, the Restricted Subsidiary Guarantors and the Trustee may amend the
Indenture,  the Notes or  the Note Guarantees,  among other things,  to cure any
ambiguity, defect  or inconsistency;  to provide  for the  assumption of  APS's,
Holding's or a Restricted Subsidiary Guarantor's obligations to Noteholders by a
Successor  Company or Successor Guarantor or a supplemental indenture in respect
of a Restricted Subsidiary Guarantee as contemplated above under "-- General" or
"-- Merger, Consolidation  and Sale  of Assets;" to  provide for  uncertificated
Notes  in addition to or  in place of certificated Notes;  or to make any change
that does not adversely affect the rights of any Noteholder. Without the consent
of each Noteholder affected, Holding or APS may not reduce the principal  amount
of  Notes the Holders  of which must  consent to an  amendment of the Indenture;
reduce the rate or extend the time  for payment of interest on any Note;  reduce
the  principal of or extend the Stated  Maturity of any Note; reduce the premium
payable upon the redemption of any Note or change the time at which any Note may
or shall be redeemed; reduce the premium  payable upon the purchase of any  Note
upon  a Change of Control  or upon an Excess Proceeds  Offer or modify the terms
pursuant to  which APS  is  obligated to  make a  Change  of Control  or  Excess
Proceeds  Offer; make any  Note payable in  money other than  that stated in the
Note; make any change in the provisions concerning waiver of Defaults or  Events
of  Default by Holders of  the Notes or rights of  Holders to receive payment of
principal or interest; make  any change in the  subordination provisions in  the
Indenture  that affects  the right  of any  Holder; or  release APS  or any Note
Guarantor from its  obligations under the  Notes, the Holding  Guarantee or  any
Restricted   Subsidiary   Guarantee   (except   pursuant   to   the   provisions
 
                                       60
<PAGE>
described above in "-- Subordination  of Note Guarantees; Release of  Restricted
Subsidiary  Guarantees" and "--  Merger, Consolidation and  Sale of Assets") and
below in "-- Satisfaction and Discharge; Defeasance."
 
SATISFACTION AND DISCHARGE; DEFEASANCE
 
    When (i) APS delivers to the Trustee all outstanding Notes (other than Notes
replaced because  of  mutilation,  loss, destruction  or  wrongful  taking)  for
cancellation  or (ii) all outstanding Notes have become due and payable, whether
at maturity or as a result of the mailing of a notice of redemption as described
above and APS irrevocably deposits with  the Trustee funds sufficient to pay  at
maturity  or upon redemption all  outstanding Notes, including interest thereon,
and if in either case APS pays all other sums payable hereunder by APS, then the
Indenture shall, subject to certain surviving provisions, cease to be of further
effect.  The  Trustee  shall  acknowledge  satisfaction  and  discharge  of  the
Indenture  on  demand of  APS  accompanied by  an  Officers' Certificate  and an
Opinion of Counsel and at the cost and expense of APS.
 
    Subject to  conditions to  defeasance described  below and  the survival  of
certain  provisions, APS at  any time may  terminate (i) all  the obligations of
APS, Holding and each Restricted Subsidiary Guarantor under the Notes, the  Note
Guarantees and the Indenture ("legal defeasance option") or (ii) the obligations
of  Holding  and  each  Restricted  Subsidiary  (including  APS)  under  certain
restrictive covenants and  the related Events  of Default ("covenant  defeasance
option"). APS may exercise its legal defeasance option notwithstanding its prior
exercise of its covenant defeasance option.
 
    If  APS exercises its legal defeasance option,  payment of the Notes may not
be accelerated because  of an Event  of Default. If  APS exercises its  covenant
defeasance  option, payment of  the Notes may  not be accelerated  because of an
Event  of  Default  specified  in  clause  (ii)  of  the  immediately  preceding
paragraph.
 
    APS  may exercise  its legal  defeasance option  or its  covenant defeasance
option only if:
 
        (a) APS irrevocably  deposits in  trust with  the Trustee  cash or  U.S.
    Government  Obligations for  the payment  of principal  and interest  on the
    Notes to maturity or redemption, as the case may be;
 
        (b) APS  delivers  to  the  Trustee  a  certificate  from  a  nationally
    recognized firm of independent certified public accountants expressing their
    opinion  that the  payments of principal  and interest when  due and without
    reinvestment will provide cash at such times and in such amounts as will  be
    sufficient  to pay principal, premium and interest when due on all the Notes
    to maturity or redemption, as the case may be;
 
        (c) 91 days pass after the deposit is made and during the 91-day  period
    no  Default described in clause (vii) or  (viii) under "-- Events of Default
    and Remedies" above occurs that is continuing at the end of the period;
 
        (d) the deposit does not constitute a default under any other  agreement
    or  instrument binding  on Holding or  any Restricted Subsidiary  and is not
    prohibited by  the provisions  described above  under "--  Subordination  of
    Notes"  or  "--  Subordination  of Note  Guarantees;  Release  of Restricted
    Subsidiary Guarantees;"
 
        (e) APS delivers to the Trustee an Opinion of Counsel to the effect that
    the trust  resulting  from the  deposit  does  not constitute,  and  is  not
    qualified  as, a regulated  investment company under  the Investment Company
    Act of 1940;
 
        (f) in the  case of  the legal defeasance  option, APS  delivers to  the
    Trustee  an Opinion of  Counsel stating that  (i) APS has  received from the
    Internal Revenue Service a ruling, or  (ii) since the date of the  Indenture
    there  has been a  change in the  applicable Federal income  tax law, to the
    effect, in either  case, that,  and based  thereon such  Opinion of  Counsel
    shall confirm that, the
 
                                       61
<PAGE>
    holders  of the Notes  will not recognize  income, gain or  loss for Federal
    income tax purposes as a  result of such defeasance  and will be subject  to
    Federal  income tax on the same amounts, in  the same manner and at the same
    times as would be the case if such defeasance were not to occur;
 
        (g) In the case of the  covenant defeasance option, APS delivers to  the
    Trustee  an Opinion of Counsel to the  effect that the Holders of such Notes
    will not recognize income, gain or loss for Federal income tax purposes as a
    result of such defeasance and will be  subject to Federal income tax on  the
    same  amounts, in the same manner and at the same times as would be the case
    if such defeasance were not to occur; and
 
        (h) APS delivers to the Trustee an Officers' Certificate and an  Opinion
    of Counsel, each stating that all conditions precedent to the defeasance and
    discharge of the Notes have been complied with as required by the Indenture.
 
REPORTS TO HOLDERS OF THE NOTES
 
    Holding  and APS shall  each file with the  Trustee and provide Noteholders,
within 15 days after they file them with the Commission, copies of their  annual
reports  and the information, documents and other reports that they are required
to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act.
Notwithstanding that  Holding may  not  be required  to  remain subject  to  the
reporting requirements of Section 13 or 15(d) of the Exchange Act, to the extent
permitted  by  the  Exchange  Act,  Holding  shall  continue  to  file  with the
Commission and provide the Trustee and  Noteholders with the annual reports  and
the  information, documents and other reports  that are specified in Sections 13
and 15(d) of the  Exchange Act. In  the event that Holding  is not permitted  to
file  such reports, documents and information with the Commission or Holding has
Subsidiaries other than APS  and its Subsidiaries that,  individually or in  the
aggregate,  would be deemed to be "substantial subsidiaries" (as defined in Rule
1-02 of  Regulation S-X,  as in  effect at  the Issue  Date), APS  will  provide
substantially similar information with respect to itself and its Subsidiaries to
the  Trustee, the Noteholders and prospective Noteholders (upon written request)
as if APS were subject to the  reporting requirements of Section 13 or 15(d)  of
the  Exchange Act,  except that  APS shall not  be required  to provide separate
financial  statements  for  any  of  its  Subsidiaries.  Without  limiting   the
foregoing,  Holding, APS and  the Restricted Subsidiary  Guarantors shall comply
with the other provisions of Trust Indenture Act Section 314(a).
 
NO PERSONAL LIABILITY OF STOCKHOLDERS, OFFICERS, DIRECTORS
 
    No director, officer,  employee, incorporator  or stockholder,  as such,  of
Holding,  APS or  any Restricted  Subsidiary Guarantor  shall have  any personal
liability in  respect of  the obligations  of Holding,  APS or  such  Restricted
Subsidiary  Guarantor, as the case may be,  under the Notes, the Note Guarantees
or the Indenture by reason of his or its status as such.
 
THE TRUSTEE
 
    The Bank of New York is the Trustee under the Indenture.
 
    The Indenture provides that,  except during the continuance  of an Event  of
Default, the Trustee will perform only such duties as are set forth specifically
in  the Indenture. During the existence of an Event of Default, the Trustee will
exercise such of the rights and powers vested in it under the Indenture and  use
the  same degree  of care and  skill in its  exercise as a  prudent Person would
exercise under the circumstances in the conduct of such Person's own affairs.

    Consolidated  Interest  Expense for  such period  shall be  calculated after
    giving effect to  such discharge  of such Indebtedness,  including with  the
    proceeds  of such new Indebtedness, as if such discharge had occurred on the

    Subsidiary shall have disposed of any  company or any business or any  group

    are the subject of such Disposal for  such period or increased by an  amount
    equal  to the  EBITDA (if negative)  directly attributable  thereto for such
    period and Consolidated Interest Expense for such period shall be reduced by
    an amount equal to the  Consolidated Interest Expense directly  attributable
    to  any  indebtedness  of  Holding  or  any  Restricted  Subsidiary  repaid,
    repurchased, defeased or  otherwise discharged with  respect to Holding  and

    such period (or, if the Capital Stock of any Restricted Subsidiary is  sold,

    business  or  any group  of  assets constituting  an  operating unit  in the
    ordinary course  of  business  (an "Acquisition  Transaction"),  EBITDA  and
    Consolidated  Interest  Expense for  such period  shall be  calculated after
    giving  pro  forma   effect  thereto  (including   the  Incurrence  of   any
    Indebtedness)  as if such Acquisition Transaction  occurred on the first day
    of such period; and
 
        (d) if since the beginning of such period, any Person (that subsequently
    became a Restricted  Subsidiary or was  merged with or  into Holding or  any
    Restricted  Subsidiary since the  beginning of such  period) shall have made
    any  Disposal  or  Acquisition  Transaction  that  would  have  required  an
    adjustment  pursuant to  clause (b)  or (c)  above if  made by  Holding or a
    Restricted Subsidiary during such  period, EBITDA and Consolidated  Interest
    Expense  for such period  shall be calculated after  giving pro forma effect
    thereto as if such Disposal or Acquisition Transaction occurred on the first
    day of such period.
 
    If any Indebtedness bears a floating rate of interest and is being given pro
forma effect, the interest expense on  such Indebtedness shall be calculated  as
if  the rate in effect on the date of determination had been the applicable rate
for  the  entire  period  (taking  into  account  any  Interest  Rate  Agreement
applicable  to such Indebtedness if such Interest Rate Agreement has a remaining
term as  at  the  date  of  determination  in  excess  of  12  months).  If  any
Indebtedness bears, at the option of Holding or a Restricted Subsidiary, a fixed
or  floating rate of interest and is  being given pro forma effect, the interest
expense on such  Indebtedness shall be  computed by applying,  at the option  of
Holding  or such Restricted Subsidiary, either a  fixed or floating rate. If any
Indebtedness that is being given pro forma effect was Incurred under a revolving
credit facility, the  interest expense  on such Indebtedness  shall be  computed
based  upon the average daily balance of such Indebtedness during the applicable
period.

                              REGISTRATION RIGHTS
 
   
    In  connection with the issuance  of the Existing Notes,  APS entered into a
Registration Agreement with the Initial Purchasers pursuant to which APS agreed,
for the benefit of the holders of the Existing Notes, at APS's cost, to use  its
best  efforts to cause the Registration Statement to be declared effective under
the Securities Act within 150  days after the date  of original issuance of  the
Existing  Notes. APS shall keep  the Exchange Offer open  for acceptance for not
less than 30 days after the date notice thereof is mailed to holders of Existing
Notes.
    
 
    In the event that  any changes in law  or applicable interpretations of  the
staff  of the Commission do not permit APS  to effect the Exchange Offer, if for
any reason the Registration Statement is not declared effective within 150  days
following  the date of original issuance of  the Existing Notes, if the Exchange
Offer is not consummated within 180 days  following the date of issuance of  the
Existing  Notes, or under certain other circumstances,  APS will, in lieu of, or
upon the request of an Initial Purchaser under certain circumstances, APS  will,
in  addition to,  effecting the  registration of the  New Notes  pursuant to the
Registration Statement and  at its cost,  (i) as promptly  as practicable,  file
with  the Commission  the Shelf Registration  Statement covering  resales of the
Existing Notes,  (ii) use  its  best efforts  to  cause the  Shelf  Registration
Statement  to be declared  effective under the  Securities Act by  the 180th day
after the original issuance of the Existing Notes (or promptly in the event of a
request by an Initial Purchaser) and (iii) keep effective the Shelf Registration
Statement until three years  after its effective date  (or until one year  after
its  effective date if such Shelf Registration Statement is filed at the request
of an  Initial Purchaser).  APS will,  in the  event of  the filing  of a  Shelf
Registration  Statement, provide to each holder of the Existing Notes covered by
the Shelf Registration Statement copies of the prospectus that is a part of  the
Shelf   Registration  Statement,  notify   each  such  holder   when  the  Shelf
Registration Statement  for the  Existing Notes  has become  effective and  take
certain  other actions  as are  required to  permit unrestricted  resales of the
Existing Notes.  A holder  of  Existing Notes  that  sells such  Existing  Notes
pursuant  to the Shelf  Registration Statement generally will  be required to be
named as a  selling securityholder in  the related prospectus  and to deliver  a
prospectus  to the purchaser, will be subject  to certain of the civil liability
provisions under the Securities  Act in connection with  such sales and will  be
bound  by the  provisions of the  Registration Agreement that  are applicable to
such holder (including certain  indemnification obligations). In addition,  each
holder  of the Existing Notes will be required to deliver information to be used
in connection with  the Shelf  Registration Statement  and to  benefit from  the
provisions regarding Special Interest set forth in the following paragraph.
 
   
    In  the event  that either  (a) the  Registration Statement  is not declared
effective prior to the 150th day following the date of original issuance of  the
Existing  Notes  or  (b)  the  Exchange Offer  is  not  consummated  or  a Shelf
Registration Statement  with  respect to  the  Existing Notes  is  not  declared
effective  on or prior to the 180th  day following the date of original issuance
of the Existing Notes, interest will accrue (in addition to the stated  interest
on  the Existing Notes)  from and including  the next day  following each of (i)
such 150-day period  in the  case of  clause (a)  above, and  (ii) such  180-day
period  in the case of  clause (b) above. In  each case such additional interest
(the "Special Interest") will  be payable in cash  semiannually in arrears  each
January  15 and  July 15, at  a rate  per annum equal  to 0.5%  of the principal
amount of the Existing Notes (determined daily). The aggregate amount of Special
Interest payable pursuant to the above  provisions will in no event exceed  1.5%
per annum of the principal amount (determined daily). Upon (x) the effectiveness
of  the Registration Statement after the  150-day period described in clause (a)
above or (y) the consummation  of the Exchange Offer  or the effectiveness of  a
Shelf  Registration  Statement, as  the case  may be,  after the  180-day period
described in clause (b) above, the  Special Interest on the Existing Notes  from
the  date of such effectiveness or consummation,  as the case may be, will cease
to accrue and all accrued  and unpaid Special Interest  as of the occurrence  of
(x)  or  (y)  shall  be paid  to  the  holders of  the  Existing  Notes promptly
thereafter. Following the occurrence of  (x) or (y) above,  as the case may  be,
the terms of the Existing Notes shall revert to the original terms.
    
 
                                       79
<PAGE>
    In  the  event that  a Shelf  Registration  Statement is  declared effective
pursuant to the  paragraph preceding  the immediately  preceding paragraph,  APS
shall   use  its  best  efforts  to   keep  such  Shelf  Registration  Statement
continuously effective in order to permit the prospectus contained therein to be
usable by holders of Existing Notes for a period of three years from the date of
the Shelf Registration Statement is declared effective by the Commission (or one
year from the date  such Shelf Registration Statement  is declared effective  if
such  Shelf  Registration Statement  is  filed upon  the  request of  an Initial
Purchaser) or such shorter period that will terminate when all the Notes covered
by the  Shelf  Registration Statement  have  been  sold pursuant  to  the  Shelf
Registration Statement.
 
    Upon consummation of the Exchange Offer, APS will have no further obligation
to  register the Existing Notes,  except in the event  that an Initial Purchaser
determines that it is not eligible to participate in the Exchange Offer and only
with respect to  Existing Notes  (if any) owned  by the  Initial Purchasers  and
acquired directly from APS.
 
    The  summary herein of certain provisions of the Registration 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 Agreement,  a copy of
which has been filed as an exhibit  to the Registration Statement of which  this
Prospectus forms a part.
 
   
                        CERTAIN FEDERAL TAX CONSEQUENCES
    
 
   
    In  the view  of the Company,  which is based  on the advice  of Debevoise &
Plimpton, special counsel to  the Company, the  principal United States  federal
income tax consequences of the acquisition, ownership and disposition of the New
Notes  to the initial acquirors thereof  and the principal United States federal
estate tax consequences of the ownership of the New Notes to such acquirors  who
are  Foreign  Holders (as  defined  below) are  as  set forth  in  the following
discussion. This discussion  is based  on currently existing  provisions of  the
Code,  existing and  proposed Treasury  regulations promulgated  thereunder, and
administrative and  judicial  interpretations  thereof,  all  as  in  effect  or
proposed  on the date  hereof and all  of which are  subject to change, possibly
with retroactive effect, or different interpretations. This discussion does  not
address  the  tax consequences  to subsequent  purchasers of  New Notes,  and is
limited to acquirors  who hold the  New Notes as  capital assets. Moreover,  the
discussion  is for general information only, and does not address all of the tax
consequences that may  be relevant  to particular  acquirors in  light of  their
personal  circumstances,  or  to certain  types  of acquirors  (such  as certain
financial institutions,  insurance companies,  tax-exempt entities,  dealers  in
securities or persons who have hedged the interest rate on the New Notes).
    
 
    PROSPECTIVE  ACQUIRORS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS AS TO THE
PARTICULAR  TAX  CONSEQUENCES  TO  THEM   OF  THE  ACQUISITION,  OWNERSHIP   AND
DISPOSITION  OF THE NEW NOTES, INCLUDING THE APPLICABILITY OF ANY FEDERAL ESTATE
OR GIFT  TAX LAWS  OR ANY  STATE,  LOCAL OR  FOREIGN TAX  LAWS, ANY  CHANGES  IN
APPLICABLE TAX LAWS AND ANY PENDING OR PROPOSED LEGISLATION OR REGULATIONS.
 
EXCHANGE OFFER
 
    The  exchange of  an Existing Note  for a  New Note should  not constitute a
taxable exchange of the Existing  Note if the interest rate  on the New Note  is
equal to the interest rate on the Existing Note. Although there is no definitive
guidance on the issue, even if the interest rate on the New Note is not equal to
the  interest rate on the  Existing Note because Special  Interest is payable on
the Existing Notes as described under "Registration Rights," but not payable  on
the  New Note,  the exchange  should not  constitute a  taxable exchange  of the
Existing Note. As a result, the New Notes should have the same issue price  (and
adjusted  issue price  immediately after  the exchange)  and the  same amount of
original issue discount, if any, as  the Existing Notes, and each holder  should
have  the same adjusted basis and  holding period in the New  Notes as it had in
the Existing Notes  immediately before  the exchange.  The following  discussion
assumes    that    the   exchange    of   Existing    Notes   for    New   Notes
 
                                       80
<PAGE>
pursuant to the Exchange Offer  will not be treated  as an exchange for  federal
income  tax purposes,  and that  the Existing  Notes and  the New  Notes will be
treated as the same security for federal income tax purposes.
 
UNITED STATES TAXATION OF UNITED STATES HOLDERS
 
   
    As used herein, the term "United States Holder" means a holder of a New Note
that is,  for  United States  federal  income tax  purposes,  (i) a  citizen  or
resident  of the United States, (ii)  a corporation, partnership or other entity
created or  organized in  or under  the  laws of  the United  States or  of  any
political subdivision thereof or (iii) an estate or trust the income of which is
subject to United States federal income taxation regardless of its source.
    
 
PAYMENT OF INTEREST ON NEW NOTES
 
    In  general, interest  paid or payable  on a New  Note will be  taxable to a
United States Holder  as ordinary  interest income  as received  or accrued,  in
accordance  with  such  holder's method  of  accounting for  federal  income tax
purposes. Assuming that  original issue  discount on  the Existing  Note is  not
greater  than a de minimis amount equal  to 0.25% of its stated principal amount
multiplied by the number  of complete years to  its maturity, any such  discount
will  be deemed to be equal to zero, and a holder will not be required to accrue
a portion of such discount as income in each taxable year.
 
   
    There is  no definitive  guidance  with respect  to  the treatment  of  debt
instruments  providing  for payments  such as  Special Interest.  Holders should
consult their  tax  advisors as  to  the  tax considerations  relating  to  debt
instruments  providing for payments such as Special Interest. In June, 1996, the
Internal Revenue Service ("IRS") issued final regulations relating to contingent
payment debt instruments (the "Contingent Payment Regulations"). The  Contingent
Payment  Regulations provide that  a payment under a  debt instrument payable on
the occurrence of a remote  or incidental contingency will  not be treated as  a
contingent  payment. The Contingent Payment Regulations would require holders of
a contingent payment debt instrument  to accrue all payments thereon  (including
de  minimis  original issue  discount and  projected  contingent payments)  on a
constant yield basis, and in certain circumstances to include market discount in
income  sooner  than  otherwise  required  and  treat  gain  recognized  on  the
disposition  of the debt  instrument as interest  income. The Contingent Payment
Regulations would apply to contingent payment debt instruments issued sixty days
or more after such  regulations are published in  the Federal Register and  thus
would  not apply, by their terms, to the  New Notes, assuming that the New Notes
are issued prior to such time. The Contingent Payment Regulations are  currently
scheduled for publication in the Federal Register on June 14, 1996. The preamble
to  the Contingent  Payment Regulations provides  that a holder  of a contingent
payment debt  instrument which  is issued  prior to  the effective  date of  the
Contingent  Payment Regulations may use any reasonable method to account for the
debt instrument, including a method that would have been required under proposed
regulations that were issued by the IRS in December, 1994. Under those  proposed
regulations,  which were  outstanding when the  Existing Notes  were issued, the
treatment of contingent payment debt instruments would generally be the same  as
the treatment under the Contingent Payment Regulations, described above.
    
 
SALE, EXCHANGE OR RETIREMENT OF THE NEW NOTES
 
    Upon  the  sale,  exchange,  redemption,  retirement  at  maturity  or other
disposition of  a New  Note, a  United States  Holder will  generally  recognize
taxable  gain or loss equal  to the difference between the  sum of cash plus the
fair market value of all other property received on such disposition (except  to
the extent such cash or property is attributable to accrued interest, which will
be  taxable as ordinary income) and such  holder's adjusted tax basis in the New
Note.
 
    Gain or loss recognized on the disposition  of a New Note generally will  be
capital  gain or loss (except to the  extent the gain is attributable to accrued
market discount, as described below) and will be long-term capital gain or  loss
if,  at the time of such disposition,  the United States Holder's holding period
for the New Note is more than one year.
 
                                       81
<PAGE>
MARKET DISCOUNT
 
    Generally, the market discount provisions of the Code require the holder  of
a  New Note that is a market discount bond (as defined in the Code) to treat any
gain realized upon the disposition  of such New Note  as interest income to  the
extent  of the market discount  that accrued during the  period such holder held
such New Note. (For  this purpose a  person disposing of  a market discount  New
Note  in a  transaction other  than a  sale, exchange  or involuntary conversion
generally is treated as realizing  an amount equal to  the fair market value  of
the New Note.) A holder may also be required to recognize as ordinary income any
principal payments with respect to a New Note to the extent such payments do not
exceed  the accrued market discount on the  New Note. For these purposes, market
discount generally equals the excess of  the stated redemption price of the  New
Note over the basis of the New Note in the hands of the holder immediately after
its  acquisition. However, market discount is deemed  not to exist if the market
discount is less than a statutorily defined de minimis amount equal to 1/4 of  1
percent  of the New  Note's contract redemption price  at maturity multiplied by
the number  of  complete years  to  the New  Note's  maturity after  the  holder
acquired the New Note.
 
    The  market discount rules  also provide that  any holder of  New Notes that
were acquired at a market discount may  be required to defer the deduction of  a
portion of the interest on any indebtedness incurred or maintained to acquire or
carry the New Notes, until the New Notes are disposed of.
 
    A  holder of a New  Note acquired at a market  discount may elect to include
market discount in income as the discount accrues. In such a case, the foregoing
rules with respect  to the recognition  of ordinary income  on dispositions  and
with  respect to the deferral of  interest deductions on indebtedness related to
such New Note would not apply.
 
AMORTIZABLE BOND PREMIUM
 
    Generally, if the tax basis of an obligation held as a capital asset exceeds
the amount payable  at maturity of  the obligation, such  excess may  constitute
amortizable  bond  premium  that the  holder  of  such obligation  may  elect to
amortize under the constant interest rate method and deduct over the period from
the holder's acquisition date to the  obligation's maturity date. A holder  that
elects  to  amortize bond  premium  must reduce  its  tax basis  in  the related
obligation  by  the  amount  of  the  aggregate  deductions  allowable  for  the
amortizable  bond premium. Any election to  amortize bond premium shall apply to
all bonds  (other than  bonds on  which the  interest is  excludible from  gross
income)  held by the holder at the beginning  of the first taxable year to which
the election  applies or  thereafter acquired  by the  holder. The  election  is
irrevocable without the consent of the IRS.
 
    In  the case of an obligation,  such as a New Note,  that may be called at a
premium prior to maturity, an earlier call date is treated as its maturity date,
and the amount of bond premium is  determined by treating the amount payable  on
such  call date as the amount payable at maturity if such a calculation produces
a smaller  amortizable bond  premium than  any  other call  date or  the  method
described  in the preceding paragraph. If a holder  of a New Note is required to
amortize and deduct bond premium by reference to a call date, the New Note  will
be treated as maturing at such date for the amount payable, and, if not redeemed
on  such date, the  New Note will  be treated as  reissued on such  date for the
amount so payable. If a New Note purchased at a premium is redeemed pursuant  to
a  call prior  to such  early call  date or  its maturity,  a purchaser  who has
elected to deduct bond premium  may deduct the excess  of its adjusted basis  in
the  New Note over the amount received on redemption (or, if greater, the amount
payable at maturity) as an ordinary loss in the taxable year of redemption.
 
    The amortizable bond premium deduction is treated as a reduction of interest
on the  bond instead  of as  a  deduction, except  as Treasury  regulations  may
otherwise provide.
 
TRANSFER
 
    The  New Notes have been issued in  registered form and will be transferable
only upon their surrender for registration of transfer. Under proposed  Treasury
regulations, a holder (other than an
 
                                       82
<PAGE>
individual) who transfers a New Note through another method may be subject to an
excise  tax  equal to  the product  of (i)  1%  of the  principal amount  of the
obligation transferred  and  (ii) the  number  of calendar  years  (or  portions
thereof) remaining until the maturity of such obligation.
 
BACKUP WITHHOLDING AND INFORMATION REPORTING
 
   
    In  general, a United States Holder of a  New Note will be subject to backup
withholding at the rate of 31% with respect to interest, principal and  premium,
if  any, paid  on a  New Note,  unless the  holder (i)  is an  entity (including
corporations, tax-exempt organizations and certain qualified nominees) which  is
exempt  from withholding  and, when  required, demonstrates  this fact,  or (ii)
provides the Company with its Taxpayer Identification Number ("TIN") (which  for
an  individual would be the holder's Social Security number), certifies that the
TIN provided to the Company is correct and that the holder has not been notified
by the IRS that  it is subject  to backup withholding  due to underreporting  of
interest  or dividends, and  otherwise complies with  applicable requirements of
the backup withholding rules. In  addition, such payments of principal,  premium
and  interest to  United States  Holders that  are not  corporations, tax-exempt
organizations or qualified  nominees will  generally be  subject to  information
reporting requirements.
    
 
    The  amount of  any backup withholding  from a  payment to a  holder will be
allowed as a credit against such  holder's federal income tax liability and  may
entitle  such  holder to  a refund,  PROVIDED that  the required  information is
furnished to the IRS.
 
UNITED STATES TAXATION OF FOREIGN HOLDERS
 
PAYMENT OF INTEREST ON NEW NOTES
 
   
    In general, payments of interest received by any holder that is not a United
States Holder  (a "Foreign  Holder") will  not  be subject  to a  United  States
federal  withholding  tax,  PROVIDED that  (i)(a)  the Foreign  Holder  does not
actually or constructively own 10% or more of the total combined voting power of
all classes of stock of the Company entitled to vote, (b) the Foreign Holder  is
not  a controlled foreign corporation that is related to the Company actually or
constructively through stock ownership and  (c) either (1) the beneficial  owner
of  the New Note, under penalties of  perjury, provides the Company or its agent
with the beneficial  owner's name and  address and  certifies that it  is not  a
United  States Holder on IRS  Form W-8 (or a suitable  substitute form) or (2) a
securities clearing organization, bank or other financial institution that holds
customers' securities in the ordinary course of its trade or business holds  the
New  Notes and certifies to the Company  or its agent under penalties of perjury
that such a Form W-8 (or suitable  substitute) has been received by it from  the
beneficial  owner  or qualifying  intermediary and  furnishes  the payor  a copy
thereof, (ii) the Foreign Holder is subject to United States federal income  tax
with  respect to  the New  Note on  a net  basis because  payments received with
respect to the New Note are effectively connected with a U.S. trade or  business
of  the Foreign Holder (in which case the  Foreign Holder may also be subject to
"branch profits tax"  under section 884  of the Code)  and provides the  Company
with  a properly executed IRS Form 4224, or (iii) the Foreign Holder is entitled
to the benefits of an income tax treaty under which the interest is exempt  from
United  States withholding  tax and  the Foreign  Holder or  such holder's agent
provides a properly executed IRS Form  1001 claiming the exemption. Payments  of
interest not exempt from U.S. federal withholding tax as described above will be
subject  to such withholding tax at the  rate of 30% (subject to reduction under
an applicable income tax treaty).
    
 
   
    In April 1996, the IRS issued proposed regulations that would change certain
of the certification and other  procedures described in the preceding  paragraph
("1996  Proposed  Regulations.")  The changes  set  forth in  the  1996 Proposed
Regulations would not materially  affect a Foreign  Holder's ability to  qualify
for  an exemption from withholding  tax with respect to  payments of interest on
the New Note. Under the 1996 Proposed Regulations, a Foreign Holder claiming the
benefit of an income tax  treaty as described in  clause (iii) of the  preceding
paragraph  (but not a  Foreign Holder claiming  the portfolio interest exemption
described in clause (i)) would be required to provide its TIN to the payor.  The
1996  Proposed  Regulations  would  apply to  payments  of  interest  made after
December 31, 1997.
    
 
                                       83
<PAGE>
SALE, EXCHANGE OR RETIREMENT OF THE NEW NOTES
 
    A Foreign Holder  generally will  not be  subject to  United States  federal
income tax (and generally no tax will be withheld) with respect to gain realized
on  the sale, exchange, redemption, retirement  at maturity or other disposition
of New Notes, unless (i) the gain is effectively connected with a United  States
trade or business conducted by the Foreign Holder, or (ii) the Foreign Holder is
an  individual  who is  present in  the United  States for  a period  or periods
aggregating 183 or more days in the taxable year of the disposition and  certain
other conditions are met.
 
   
    With respect to a Foreign Holder subject to United States federal income tax
as  described in the preceding paragraph, an  exchange of an Existing Note for a
New Note should not constitute  a taxable exchange of  the Existing Note if  the
interest  rate on  the New Note  is equal to  the interest rate  on the Existing
Note. Although  there  is no  definitive  guidance on  the  issue, even  if  the
interest  rate on the New Note is not equal to the interest rate on the Existing
Note because Special  Interest is  payable on  the Existing  Note, as  described
under  "Registration  Rights," but  not payable  on the  New Note,  the exchange
should not constitute  a taxable  exchange of  the Existing  Note. As  described
under "United States Taxation of United States Holders -- Payment of Interest on
New  Notes," there is  no definitive guidance  with respect to  the treatment of
debt instruments  providing  for payments  such  as Special  Interest,  and  the
Contingent  Payment Regulations may  affect the treatment  of the disposition of
certain contingent  payment instruments  issued sixty  days or  more after  such
regulations  are  published  in  the Federal  Register.  The  Contingent Payment
Regulations are currently scheduled for  publication in the Federal Register  on
June  14,  1996.  Holders  should  consult their  tax  advisors  as  to  the tax
considerations relating  to  the treatment  of  debt instruments  providing  for
payments such as Special Interest.
    
 
BACKUP WITHHOLDING AND INFORMATION REPORTING
 
    Under  current  Treasury  regulations,  backup  withholding  and information
reporting on IRS Form  1099 do not apply  to payments made by  the Company or  a
paying  agent to  Foreign Holders if  the certification  described under "United
States Taxation  of Foreign  Holders --  Payment of  Interest on  New Notes"  is
received, provided that the payor does not have actual knowledge that the holder
is a United States Holder. If any payments of principal and interest are made to
the beneficial owner of a New Note by or through the foreign office of a foreign
custodian,  foreign nominee or other foreign  agent of such beneficial owner, or
if the foreign  office of a  foreign "broker" (as  defined in applicable  United
States  Treasury Department regulations) pays the proceeds  of the sale of a New
Note to the seller  thereof, backup withholding  and information reporting  will
not  apply. Information reporting requirements (but not backup withholding) will
apply, however, to a payment  by a foreign office of  a broker that is a  United
States  person, that derives 50% or more of its gross income for certain periods
from the conduct  of a  trade or business  in the  United States, or  that is  a
"controlled foreign corporation" (generally, a foreign corporation controlled by
United States shareholders) with respect to the United States, unless the broker
has  documentary evidence in its records that the holder is a Foreign Holder and
certain other  conditions  are  met,  or the  holder  otherwise  establishes  an
exemption.  Payment by  a United States  office of  a broker is  subject to both
backup withholding at a rate of 31% and information reporting unless the  holder
certifies  under penalties of perjury that it  is a Foreign Holder, or otherwise
establishes an  exemption. A  Foreign Holder  may obtain  a refund  or a  credit
against  such Holder's U.S. federal income tax liability of any amounts withheld
under the  backup  withholding  rules,  provided  the  required  information  is
furnished to the IRS.
 
    In  addition, in  certain circumstances  interest on a  New Note  owned by a
Foreign Holder will be required  to be reported annually  on IRS Form 1042S,  in
which  case such form  will be filed with  the IRS and  furnished to the Foreign
Holder.
 
FEDERAL ESTATE TAXES
 
    Subject to applicable estate  tax treaty provisions, New  Notes held at  the
time  of death (or theretofore transferred subject to certain retained rights or
powers) by an individual who at the time  of death is a Foreign Holder will  not
be   included  in  such   holder's  gross  estate   for  United  States  federal
 
                                       84
<PAGE>
estate tax  purposes, PROVIDED  that (a)  the individual  does not  actually  or
constructively own 10% or more of the total combined voting power of all classes
of  stock of the Company entitled  to vote and (b) the  income and the New Notes
are not  effectively connected  with the  conduct of  a United  States trade  or
business by the individual.
 
                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
    CD&R  was paid a  management fee by  the Company of  $300,000 for the fiscal
year ended January 27,  1996, for financial  advisory and management  consulting
services.  The Company  expects to  continue to pay  CD&R similar  fees for such
services in  the  future.  The amount  of  such  fees will  be  determined  with
reference  to (i) the size of the  Company's revenues and profits, (ii) the type
and magnitude of  such advisory  and management consulting  services then  being
provided, (iii) the fees then being paid to CD&R by other companies for which it
provides similar services and (iv) the fees then being charged by other managers
with  comparable  organizations for  similar services  provided to  companies in
which investment funds managed by such managers have invested. Although there is
no specific formula for determining the fees to be paid to CD&R for advisory and
management consulting services in the future and there is no agreement with CD&R
that the fee be limited to a  specific amount, all such future fees are  subject
to  approval of the Company's Board of Directors and are limited to $500,000 per
year under the New Credit Agreement.
 
   
    The Company has entered into an Indemnification Agreement in favor of  CD&R,
Fund  IV  and Associates  (together with  their respective  directors, officers,
partners, employees, agents and controlling persons, the "Indemnitees") pursuant
to which the Company has agreed, subject to certain exceptions, to indemnify and
hold harmless the members of the boards of directors of Holding and APS, to  the
full extent permitted by Delaware law, and to indemnify the Indemnitees from and
against  any suits,  claims, damages  or expenses  that may  be made  against or
incurred by them under applicable  securities laws in connection with  offerings
of securities of the Company, including the Exchange Offer, liabilities to third
parties  arising out of any action or failure  to act by the Company and, except
in the case of gross negligence or intentional misconduct, the provision by CD&R
of management consulting and financial advisory services.
    
 
MANAGEMENT AND DIRECTORS
 
    Holding and APS have guaranteed bank loans used by employees of the  Company
to  purchase Class A Common Stock of Holding. The aggregate amount of such loans
outstanding at  January 29,  1994, January  28, 1995  and January  27, 1996  was
approximately $1,434,000, $633,000 and $505,000, respectively.
 
   
    In  March 1993,  the Company entered  into an asset  purchase agreement with
Prince-Oracle Auto Parts and Equipment, Inc. ("Prince-Oracle") for the  purchase
of  the assets of six automotive parts stores in Arizona for a purchase price of
approximately $2.9 million, consisting of $1.8 million in cash and a twenty-year
promissory note issued to Prince-Oracle in the principal amount of $1.1 million.
Subsequent to such purchase, Stephen  H. Sattinger, the owner of  Prince-Oracle,
joined  the Company as an executive  officer. The promissory note bears interest
at a rate of 7.5%  per annum and is payable  over twenty years in equal  monthly
installments of principal and interest. The promissory note is collateralized by
a  security  interest in  certain assets  relating  to the  former Prince-Oracle
stores. Interest  expense on  the Prince-Oracle  note was  $75,000, $80,000  and
$78,000  for the years ended January 29,  1994, January 28, 1995 and January 27,
1996, respectively.
    
 
                              PLAN OF DISTRIBUTION
 
    Each broker-dealer that receives New Notes  for its own account pursuant  to
the  Exchange Offer  in exchange for  Existing Notes, where  such Existing Notes
were acquired by such broker-dealer as  a result of market-making activities  or
other  trading activities,  must acknowledge  and agree  that it  will deliver a
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 for a period of
one year after the Expiration
 
                                       85
<PAGE>
   
Date  by a  broker-dealer in  connection with resales  of New  Notes received in
exchange for Existing Notes where such Existing Notes were acquired as a  result
of  market-making activities or other trading activities. The Company has agreed
that, starting on the Expiration  Date and ending on  the close of business  one
year  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  broker-dealers  who  may  receive
compensation   in  the  form  of  commissions   or  concessions  from  any  such
broker-dealer and/or the  purchasers 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 person that participates in the 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
commissions  or concessions  received by  any such persons  may be  deemed to be
underwriting compensation under  the Securities Act.  The Letter of  Transmittal
states that by acknowledging and agreeing 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 one  year  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
incident to the  Exchange Offer  other than  commissions or  concessions of  any
brokers  or dealers and will  indemnify the holders of  the Notes (including any
broker-dealers) against  certain liabilities,  including liabilities  under  the
Securities Act.
 
    By  acceptance of this Exchange Offer,  each broker-dealer agrees that, upon
receipt of notice from the Company of the happening of any event which makes any
statement in the Prospectus untrue in any material respect or which requires the
making of any changes in the Prospectus in order to make the statements  therein
not  misleading, such broker-dealer will suspend use of the Prospectus until (i)
the  Company  has  amended  or  supplemented  the  Prospectus  to  correct  such
misstatement or omission and (ii) either the Company has furnished copies of the
amended  or supplemented Prospectus to such broker-dealer or, if the Company has
not otherwise agreed to  furnish such copies  and declines to  do so after  such
broker-dealer  so  requests,  such broker-dealer  has  obtained a  copy  of such
amended or supplemented Prospectus as filed with the Commission. The Company has
agreed to  deliver  such notice  and  such amended  or  supplemented  Prospectus
promptly to any Participating Broker-Dealer that has so notified the Company.
 
    Pursuant  to the  Registration Agreement, APS  and Holding  have jointly and
severally  agreed   to  indemnify   the  Initial   Purchasers  against   certain
liabilities,  including  certain  liabilities incurred  in  connection  with the
offering  of  the  Existing  Notes,  and  contribute  to  payments  the  Initial
Purchasers may be required to make in respect thereof.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors of
  Parts, Inc.
 
    We have audited the accompanying balance sheet of Parts, Inc. as of December
31,  1995 and the related statements of  income and accumulated deficit and cash
flows for the year then ended. These financial statements are the responsibility
of the Company's  management. Our  responsibility is  to express  an opinion  on
these financial statements based on our audit.
 
    We  conducted  our  audit  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
misstatements. 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 audit provides reasonable basis for our opinion.
 
    As discussed in Note 1 to the financial statements, the Parent Company  sold
its investment in the Company.
 
    In  our opinion, the financial statements  referred to above present fairly,
in all material respects, the financial  position of Parts, Inc. as of  December
31, 1995, and the results of its operations and its cash flows for the year then
ended in conformity with generally accepted accounting principles.

    Inventories,  which consist principally of  replacement automobile parts and
accessories, are stated at the lower of cost or market. Cost is determined using
the last-in, first-out  (LIFO) method.  The first-in, first-out  (FIFO) cost  of
LIFO  valued inventories exceeds their LIFO basis  by $14,403 as of December 31,
1995. During  1995 inventory  was reduced  resulting in  a liquidation  of  LIFO
inventory quantities. The effect of the 1995 liquidation decreased cost of goods
sold approximately $267 for the year ended December 31, 1995.
 
PROPERTY, PLANT AND EQUIPMENT
 
    Property, plant and equipment are recorded at cost and are depreciated using
the  declining  balance  method  for warehouse,  shop  equipment,  furniture and
equipment, and  the  straight-line method  for  the other  categories  over  the
estimated useful lives of the assets.

    Major   renewals  and   betterments  are   capitalized  while  replacements,
maintenance and  repairs  which  do not  improve  or  extend the  lives  of  the
respective assets are expensed currently. Gain or loss on retirement or disposal
of individual assets is recorded as income or expense.
    
 
INTANGIBLE ASSETS
 
    Intangible  assets are recorded at  cost, less accumulated amortization, and
represents the  unamortized excess  of  cost over  the  net tangible  assets  of
businesses  acquired. Amortization  is provided  using the  straight-line method
over  various  periods  not  exceeding  forty  years.  Amortization  expense  of
intangibles was $194 for 1995.
 
INCOME TAXES
 
    Deferred  income  tax  assets and  liabilities  are recognized  for  the tax
consequences of "temporary differences" by applying enacted statutory tax  rates
applicable to future years to differences between

the  financial  carrying  amounts  and  the tax  basis  of  existing  assets and
liabilities. The effect on deferred taxes of a change in tax rates is recognized
in income in the period that includes the enactment date.
 
    Recognition of deferred tax assets is  based on management's belief that  it
is  more  likely  than  not  that  the  tax  benefit  associated  with temporary
differences will be realized.
 
    The Company is included in a consolidated federal income tax return with its
ultimate U.S. parent company. The tax sharing agreement between the Company  and
its  Parent Company provides for reimbursement  when losses of one member reduce
the tax liability of another member.  Current and deferred taxes are  calculated
by the Company as if it were a separate taxpayer.
 
USE OF ESTIMATES
 
    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 and
disclosures of contingent assets  and liabilities at the  date of the  financial
statement. Actual results could differ from those estimates.

3.  POST-RETIREMENT BENEFITS OTHER THAN PENSIONS:
    The  Company offers a Medicare supplement plan to substantially all retirees
after the age  of 65  if they  are active full-time  employees on  the day  they
retire  (and have 10 years of service for employees hired after January 1, 1993)
and a post-retirement life insurance plan  to all retirees on the Medicare  plan
after the age of 65.
 
    The   supplement  plan   covers  Medicare   co-pays  and   coinsurance.  The
post-retirement life plan provides an insurance  benefit of $10 ($5 for  certain
grandfathered  retirees). Neither plan covers spouses or dependents. The Company
has reserved the right to change the benefits and eligibility rules.

    At December 5,  1995 the Company  decided to terminate  the plans. The  $770
liability  represents  the amount  incurred as  full settlement  in lieu  of the
vested benefits at date of plan termination.
 
4.  EMPLOYEE BENEFIT PLANS:
    The  employees  of  the  Company  and  its  subsidiaries  are  eligible   to
participate  in a defined contribution retirement  savings plan sponsored by the
Company.  Generally,  an  employee  becomes  eligible  to  participate  in   and
contribute  to the  plan after  one year  of service  and the  attainment of age
twenty-one. The Company's contributions to the plan are based on a percentage of
the participant's compensation. During 1995, the Company's contribution  expense
to the plan totaled $828.
 
5.  LEASES:
    Certain   lease  buildings,  warehouses,  stores  and  equipment  are  under
non-cancelable operating lease agreements which expire at various dates  through
2004. The leases generally provide that the company pay the taxes, insurance and
maintenance  expenses related  to the leased  assets. In many  cases, the leases
provide for renewal options of 5 to 10 years.

    Rent expense charged to continuing operations in 1995 was $9,142.
 
6.  RELATED PARTY:
    The  Company has an informal loan agreement  with its Parent Company, for up
to $125 million in advances. The parent company has stated that, so long as  the
Company  remains a wholly owned subsidiary, sufficient funds will continue to be
made available to the business such that  the obligations of the Company can  be
met.  All amounts due to  the Parent Company have  been classified as short-term
debt at December 31, 1995.
 
    Interest on the  portion of the  advance from parent  deemed to be  interest
bearing  ($32,266 at  December 31, 1995)  accrues at  a rate equal  to the prime
commercial rate (8.5% at December 31, 1995) less 2%. Interest expense of  $2,562
in 1995 was incurred relating to indebtedness to the Parent Company.
 
7.  COMMITMENTS AND CONTINGENCIES:
    Legal  actions  incident  to the  ordinary  course of  business  are pending
against the Company. In the opinion  of management, the eventual disposition  of
these  matters will have no material adverse effect on the financial position or
results of operations of the Company.
 
    Certain of the Company's  customers finance a  portion of their  inventories
through  financial institutions. Under the terms  of the arrangements with these
financial institutions, the Company may  be required, in limited  circumstances,
to repurchase inventory collateralizing the borrowings.

                                    PART II
                     INFORMATION NOT REQUIRED IN PROSPECTUS
 
   
ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
    
 
    Section 145 of the Delaware General Corporation Law, as amended, provides in
regards to indemnification of directors and officers as follows:
 
    145.   Indemnification  of   Officers,  Directors,   Employees  and  Agents;
Insurance.
 
    (a) A corporation  may indemnify  any person  who was or  is a  party or  is
threatened  to be made a  party to any threatened,  pending or completed action,
suit or  proceeding, whether  civil, criminal,  administrative or  investigative
(other  than an action by or  in the right of the  corporation) by reason of the
fact that  he  is  or  was  a  director,  officer,  employee  or  agent  of  the
corporation,  or  is or  was  serving at  the request  of  the corporation  as a
director, officer, employee or agent of another corporation, partnership,  joint
venture,  trust  or  other enterprise,  against  expenses  (including attorneys'
fees), judgments, fines and amounts  paid in settlement actually and  reasonably
incurred  by him in connection with such  action, suit or proceeding if he acted
in good faith and in a manner he reasonably believed to be in or not opposed  to
the  best interests of the corporation, and, with respect to any criminal action
or proceeding, had no reasonable cause to believe his conduct was unlawful.  The
termination  of any action,  suit or proceeding  by judgment, order, settlement,
conviction, or upon a plea of NOLO  CONTENDERE or its equivalent, shall not,  of
itself,  create a presumption that the person did not act in good faith and in a
manner which  he  reasonably believed  to  be in  or  not opposed  to  the  best
interests  of  the corporation,  and,  with respect  to  any criminal  action or
proceeding, had reasonable cause to believe that his conduct was unlawful.
 
    (b) A corporation  may indemnify  any person  who was or  is a  party or  is
threatened  to be made a party to any threatened, pending or completed action or
suit by or in the right of the corporation to procure a judgment in its favor by
reason of the fact that he is or  was a director, officer, employee or agent  of
the  corporation, or is  or was serving at  the request of  the corporation as a
director, officer, employee or agent of another corporation, partnership,  joint
venture,  trust or other enterprise against expenses (including attorneys' fees)
actually and  reasonably incurred  by  him in  connection  with the  defense  or
settlement  of such action or suit if he acted  in good faith and in a manner he
reasonably believed  to be  in  or not  opposed to  the  best interests  of  the
corporation  and except that no indemnification shall  be made in respect of any
claim, issue or matter as  to which such person shall  have been adjudged to  be
liable  to  the corporation  unless and  only to  the extent  that the  Court of
Chancery or the court in which such  action or suit was brought shall  determine
upon  application that, despite the adjudication of liability but in view of all
the circumstances of the case, such person is fairly and reasonably entitled  to
indemnity  for such  expenses which  the Court of  Chancery or  such other court
shall deem proper.
 
    (c) To  the  extent  that  a  director, officer,  employee  or  agent  of  a
corporation  has been successful  on the merits  or otherwise in  defense of any
action, suit  or proceeding  referred to  in  subsections (a)  and (b)  of  this
section,  or  in defense  of any  claim, issue  or matter  therein, he  shall be
indemnified against expenses (including attorneys' fees) actually and reasonably
incurred by him in connection therewith.
 
    (d) Any  indemnification  under subsections  (a)  and (b)  of  this  section
(unless  ordered by a court) shall be made by the corporation only as authorized
in the specific case upon a determination that indemnification of the  director,
officer, employee or agent is proper in the circumstances because he has met the
applicable  standard of  conduct set  forth in subsections  (a) and  (b) of this
section. Such determination shall  be made (1) by  a majority vote of  directors
who  are not parties to such action, suit or proceeding, even though less than a
quorum, or (2) if there are no  such directors, or if such directors so  direct,
by independent legal counsel in a written opinion, or (3) by the stockholders.
 
                                      II-1
<PAGE>
    (e)  Expenses (including attorneys' fees) incurred by an officer or director
in defending any civil, criminal,  administrative or investigative action,  suit
or proceeding may be paid by the corporation in advance of the final disposition
of  such action,  suit or  proceeding upon  receipt of  an undertaking  by or on
behalf of such director or officer to  repay such amount if it shall  ultimately
be  determined that he is  not entitled to be  indemnified by the corporation as
authorized in this section. Such  expenses (including attorneys' fees)  incurred
by  other employees and agents may be so paid upon such terms and conditions, if
any, as the board of directors deems appropriate.
 
    (f) The indemnification and advancement of expenses provided by, or  granted
pursuant to, the other subsections of this section shall not be deemed exclusive
of  any other  rights to which  those seeking indemnification  or advancement of
expenses may be  entitled under any  bylaw, agreement, vote  of stockholders  or
disinterested directors or otherwise, both as to action in his official capacity
and as to action in another capacity while holding such office.
 
    (g)  A corporation  shall have power  to purchase and  maintain insurance on
behalf of any person who is or was a director, officer, employee or agent of the
corporation, or  is or  was  serving at  the request  of  the corporation  as  a
director,  officer, employee or agent of another corporation, partnership, joint
venture, trust or other  enterprise against any  liability asserted against  him
and  incurred by him in any such capacity, or arising out of his status as such,
whether or not  the corporation would  have the power  to indemnity him  against
such liability under this section.
 
    (h)  For purposes  of this  section, references  to "the  corporation" shall
include, in addition to the  resulting corporation, any constituent  corporation
(including  any constituent  of a  constituent) absorbed  in a  consolidation or
merger which, if its separate existence had continued, would have had power  and
authority to indemnify its directors, officers, and employees or agents, so that
any  person  who  is or  was  a director,  officer,  employee or  agent  of such
constituent corporation, or is or was serving at the request of such constituent
corporation as a director,  officer, employee or  agent of another  corporation,
partnership,  joint venture, trust or other  enterprise, shall stand in the same
position  under  this  section  with  respect  to  the  resulting  or  surviving
corporation as he would have with respect to such constituent corporation if its
separate existence had continued.
 
    (i)  For purposes of  this section, references  to "other enterprises" shall
include employee benefit plans; references  to "fines" shall include any  excise
taxes  assessed  on a  person with  respect  to any  employee benefit  plan; and
references to "serving  at the  request of  the corporation"  shall include  any
service  as  a director,  officer, employee  or agent  of the  corporation which
imposes duties on, or involves services by, such director, officer, employee, or
agent  with  respect  to   an  employee  benefit   plan,  its  participants   or
beneficiaries;  and  a  person  who acted  in  good  faith and  in  a  manner he
reasonably believed to be in the interest of the participants and  beneficiaries
of  an employee  benefit plan  shall be deemed  to have  acted in  a manner "not
opposed to  the  best interests  of  the corporation"  as  referred to  in  this
section.
 
    (j)  The indemnification and advancement of expenses provided by, or granted
pursuant  to, this section  shall, unless otherwise  provided when authorized or
ratified, continue as  to a person  who has  ceased to be  a director,  officer,
employee  or agent and  shall inure to  the benefit of  the heirs, executors and
administrators of such a person.
 
   
        Article VI of the Holding By-Laws provides in regard to  indemnification
    of directors and officers as follows:
    
 
        Section 6.01.  NATURE OF INDEMNITY.  The Corporation shall indemnify any
    person  who was or  is a party  or is threatened  to be made  a party to any
    threatened, pending or completed action, suit or proceeding, whether  civil,
    criminal,  administrative or investigative, by reason of the fact that he or
    she is  or  was or  has  agreed  to become  a  director or  officer  of  the
    Corporation,  or is or was serving or has  agreed to serve at the request of
    the  Corporation  as   a  director  or   officer  of  another   corporation,
    partnership,  joint  venture, trust  or  other enterprise,  against expenses
    (including attorneys' fees), judgments, fines and amounts paid in settlement
    actually and reasonably
 
                                      II-2
<PAGE>
   
    incurred by him or  on his behalf  in connection with  such action, suit  or
    proceeding  and any  appeal therefrom, if  he acted  in good faith  and in a
    manner he reasonably believed to be in or not opposed to the best  interests
    of  the Corporation, and, with respect to any criminal action or proceeding,
    had no reasonable cause to believe his conduct was unlawful; except that  in
    the  case of  an action or  suit by  or in the  right of  the Corporation to
    procure a judgment in its favor (1) such indemnification shall be limited to
    expenses (including  attorneys' fees)  actually and  reasonably incurred  by
    such  person in the defense or settlement of such action or suit, and (2) no
    indemnification shall be made in respect of any claim, issue or matter as to
    which such person shall have been  adjudged to be liable to the  Corporation
    unless  and only to  the extent that  the Delaware Court  of Chancery or the
    court in  which  such  action  or suit  was  brought  shall  determine  upon
    application  that, despite the adjudication of  liability but in view of all
    the circumstances of the case, such person is fairly and reasonably entitled
    to indemnity for such expenses which the Delaware Court of Chancery or  such
    other court shall deem proper.
    
 
   
        The  termination of any  action, suit or  proceeding by judgment, order,
    settlement, conviction, or upon a plea of NOLO CONTENDERE or its  equivalent
    shall  not, of itself, create  a presumption that the  person did not act in
    good faith and  in a manner  which he reasonably  believed to be  in or  not
    opposed  to the best interests of the  Corporation, and, with respect to any
    criminal action  or proceeding,  had reasonable  cause to  believe that  his
    conduct was unlawful.
    
 
        Section  6.02.   SUCCESSFUL  DEFENSE.   To the  extent that  a director,
    officer, employee or  agent of the  Corporation has been  successful on  the
    merits or otherwise in defense of any action, suit or proceeding referred to
    in  Section 6.01 hereof or in defense of any claim, issue or matter therein,
    he  shall  be  indemnified  against  expenses  (including  attorneys'  fees)
    actually and reasonably incurred by him in connection therewith.
 
        Section  6.03.    DETERMINATION  THAT INDEMNIFICATION  IS  PROPER.   Any
    indemnification of a director  or officer of  the Corporation under  Section
    6.01  hereof (unless ordered  by a court)  shall be made  by the Corporation
    unless a  determination is  made  that indemnification  of the  director  or
    officer  is  not proper  in the  circumstances  because he  has not  met the
    applicable standard  of  conduct  set  forth in  Section  6.01  hereof.  Any
    indemnification  of an  employee or agent  of the  Corporation under Section
    6.01 hereof (unless ordered by a court) may be made by the Corporation  upon
    a  determination that indemnification of the  employee or agent is proper in
    the circumstances because he has met the applicable standard of conduct  set
    forth  in Section 6.01 hereof.  Any such determination shall  be made (1) by
    the Board  of  Directors  by a  majority  vote  of a  quorum  consisting  of
    directors who were not parties to such action, suit or proceeding, or (2) if
    such  a  quorum  is not  obtainable,  or,  even if  obtainable  a  quorum of
    disinterested directors  so  directs,  by independent  legal  counsel  in  a
    written opinion, or (3) by the stockholders.
 
        Section  6.04.    ADVANCE  PAYMENT  OF  EXPENSES.    Expenses (including
    attorney' fees) incurred by  a director or officer  in defending any  civil,
    criminal,  administrative or investigative action,  suit or proceeding shall
    be paid  by the  Corporation in  advance of  the final  disposition of  such
    action, suit or proceeding upon receipt of an undertaking by or on behalf of
    the  director or  officer to  repay such  amount if  it shall  ultimately be
    determined that he is not entitled  to be indemnified by the Corporation  as
    authorized  in  this  Article.  Such  expenses  (including  attorneys' fees)
    incurred by other employees and  agents may be so  paid upon such terms  and
    conditions,   if  any,  as   the  Board  of   Directors  may  authorize  the
    Corporation's counsel to represent such director, officer, employee or agent
    in any action, suit or proceeding, whether or not the Corporation is a party
    to such action, suit or proceeding.
 
        Section  6.05.     PROCEDURE  FOR  INDEMNIFICATION   OF  DIRECTORS   AND
    OFFICERS.   Any indemnification of a  director or officer of the Corporation
    under Sections 6.01 and 6.02, or advance of costs, charges and expenses to a
    director or  officer under  Section  6.04 of  this  Article, shall  be  made
    promptly,  and in any event within 30  days, upon the written request of the
    director or officer. If a determination by the Corporation that the director
    or officer is entitled to indemnification
 
                                      II-3
<PAGE>
   
    pursuant to this Article is required,  and the Corporation fails to  respond
    within  sixty days to a written request for indemnity, the Corporation shall
    be deemed to have approved such request. If the Corporation denies a written
    request for indemnity or advancement of expenses, in whole or in part, or if
    payment in full pursuant to such request is not made within thirty days, the
    right to indemnification  or advances as  granted by this  Article shall  be
    enforceable   by  the  director  or  officer   in  any  court  of  competent
    jurisdiction. Such person's costs and  expenses incurred in connection  with
    successfully establishing his right to indemnification, in whole or in part,
    in any such action shall also be indemnified by the Corporation. It shall be
    a  defense to  any such action  (other than  an action brought  to enforce a
    claim for the advance of costs,  charges and expenses under Section 6.04  of
    this  Article where the  required undertaking, if any,  has been received by
    the Corporation) that the claimant has  not met the standard of conduct  set
    forth  in  Section 6.01  of this  Article,  but the  burden of  proving such
    defense shall be on the Corporation. Neither the failure of the  Corporation
    (including  its Board of  Directors, its independent  legal counsel, and its
    stockholders) to have made a determination prior to the commencement of such
    action that indemnification of the  claimant is proper in the  circumstances
    because  he has met the applicable standard  of conduct set forth in Section
    6.01  of  this  Article,  nor  the  fact  that  there  has  been  an  actual
    determination  by  the Corporation  (including its  Board of  Directors, its
    independent legal counsel, and its  stockholders) that the claimant has  not
    met such applicable standard of conduct, shall be a defense to the action or
    create  a presumption that the claimant  has not met the applicable standard
    of conduct.
    
 
   
        Section 6.06.  SURVIVAL;  PRESERVATION OF OTHER  RIGHTS.  The  foregoing
    indemnification  provisions shall  be deemed  to be  a contract  between the
    Corporation and each director, officer, employee and agent who serves in any
    such capacity at  any time while  these provisions as  well as the  relevant
    provisions  of the Delaware  General Corporation Law are  in effect, and any
    repeal or modification thereof shall not affect any right or obligation then
    existing with respect to any state  of facts then or previously existing  or
    any   action,  suit  or  proceeding  previously  or  thereafter  brought  or
    threatened based in whole or  in part upon any such  state of facts. Such  a
    "contract  right" may not  be modified retroactively  without the consent of
    such director, officer, employee or agent.
    
 
        The indemnification  provided  by  this  Article  shall  not  be  deemed
    exclusive  of any  other rights to  which those indemnified  may be entitled
    under any by-law, agreement, vote of stockholders or disinterested directors
    or otherwise, both as to action in his official capacity and as to action in
    another capacity  while holding  such office,  and shall  continue as  to  a
    person who has ceased to be a director, officer, employee or agent and shall
    inure  to the benefit of  the heirs, executors and  administrators of such a

    asserted  against  him and  incurred by  him or  on his  behalf in  any such
    capacity, or  arising  out  of  his  status as  such,  whether  or  not  the

        (b) In  addition  to  the  matters  required to  be  set  forth  in  the
    certificate  of  incorporation  by  subsection  (a)  of  this  section,  the
    certificate of incorporation may  also contain any or  all of the  following
    matters:
 
                                      * * * *
 
   
        (7)  A provision  eliminating or  limiting the  personal liability  of a
    director to the  corporation or  its stockholders for  monetary damages  for
    breach  of fiduciary duty as a  director, provided that such provision shall
    not eliminate or limit the  liability of a director:  (i) for any breach  of
    the  director's duty of loyalty to the corporation or its stockholders; (ii)
    for acts  or  omissions not  in  good  faith or  which  involve  intentional

    such other person or persons,  if any, who, pursuant  to a provision of  the
    certificate of incorporation in accordance with Section141(a) of this title,
    exercise  or  perform any  of the  powers or  duties otherwise  conferred or
    imposed upon the board of directors by this title.

    limit the liability of a director (i) for any breach of the director's  duty
    of  loyalty  to  the  Corporation  or its  stockholders,  (ii)  for  acts or
    omissions not in  good faith or  which involve intentional  misconduct or  a
    knowing  violation  of  the law,  (iii)  under  Section 174  of  the General
    Corporation Law of the  State of Delaware or  (iv) for any transaction  from
    which the director derived an improper personal benefit.

ITEM 22.  UNDERTAKINGS
 
    Each of the undersigned Registrants hereby undertakes:
 
        (1) That, for purposes of determining any liability under the Securities
    Act of 1933,  each filing  of Holding's  annual report  pursuant to  section
    13(a)  or  section 15(d)  of the  Securities  Exchange Act  of 1934  that is
    incorporated by reference in the  registration statement 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 the initial  bona
    fide offering thereof.
 
        (2)  Insofar  as  indemnification  for  liabilities  arising  under  the
    Securities Act of 1933 may be permitted to directors, officers, and  persons
    controlling   the  Registrants  pursuant  to  the  foregoing  provisions  or
    otherwise, the Registrants  have been  advised that  in the  opinion of  the
    Securities  and Exchange  Commission such indemnification  is against public
    policy as expressed in the Securities 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  person controlling the  Registrants in the  successful
    defense  of any  action, suit or  proceeding) is asserted  by such director,
    officer, or person in connection with the securities
 
                                      II-6
<PAGE>
    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  Securities Act  and  will  be
    governed by the final adjudication of such issue.
 
        (3)  To  respond to  requests for  information  that is  incorporated by
    reference into the Prospectus pursuant  to Item 4, 10(b),  11 or 13 of  Form
    S-4,  within one business  day of receipt  of such request,  and to send the
    incorporated documents by  first-class mail  or equally  prompt means.  This
    includes   information  contained  in  documents  filed  subsequent  to  the
    effective date of the registration statement through the date responding  to
    the request.
 
        (4)  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.

                     Offer to Exchange $100,000,000 Senior
                       Subordinated Notes of A.P.S., Inc.
                     -------------------------------------
 
Ladies and Gentlemen:
 
    We  have acted  as special counsel  to A.P.S., Inc.,  a Delaware corporation
("APS"), in connection with the preparation  and filing with the Securities  and
Exchange  Commission (the  "Commission") under  the Securities  Act of  1933, as
amended (the "Act"), of  a Registration Statement on  Form S-4 (as amended,  the
"Registration   Statement"),   which  includes   a   form  of   prospectus  (the
"Prospectus") relating  to  the  proposed  offering  of  $100,000,000  aggregate
principal  amount of APS's 11 7/8% Senior  Subordinated Notes Due 2006 (the "New
Notes"), which are  to be registered  under the  Act, in exchange  for an  equal
principal  amount of its outstanding 11  7/8% Senior Subordinated Notes Due 2006
(the "Existing Notes").
 
    In so acting,  we have  examined and relied  upon the  originals, or  copies
certified  or  otherwise  identified  to  our  satisfaction,  of  such corporate
records, documents, certificates and  other instruments as  in our judgment  are
necessary or appropriate to enable us to render the opinion expressed below.
 
    We  are of  the opinion  that the New  Notes to  be offered  pursuant to the
Registration Statement  have been  duly authorized  by all  necessary  corporate
action  on the part of  APS and, upon the  issuance of the New  Notes by APS and
authentication by  The  Bank  of  New  York  (the  "Trustee")  pursuant  to  the
Indenture,  dated as  of January  25, 1996,  among APS,  as issuer,  APS Holding
Corporation, American  Parts System,  Inc., Big  A Auto  Parts, Inc.,  Autoparts
Finance  Company, Inc., APS  Supply, Inc., A.P.S.  Management Services, Inc. and
Parts, Inc.,  as Guarantors,  and the  Trustee, the  New Notes  will be  validly
issued  and will  be legal,  valid and  binding obligations  of APS, enforceable
against APS  in  accordance  with their  terms,  except  as may  be  limited  by
bankruptcy,  insolvency, reorganization, moratorium or  similar laws relating to
or affecting  creditors' rights  generally or  by general  principles of  equity
(regardless  of whether such enforceability is considered in an action at law or
in equity).
 
    We express  no  opinion as  to  the effect  of  any Federal  or  state  laws
regarding fraudulent transfers or conveyances.
 
    We  consent to the filing of this  opinion as an exhibit to the Registration
Statement and to  the use of  our name  under the headings  "Legal Matters"  and
"Certain Federal Tax Consequences" in the Prospectus. In giving such consent, we
do  not hereby concede that we are  within the category of persons whose consent
is required under  Section 7  of the  Act or the  rules and  regulations of  the
Commission thereunder.

              PLEASE READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY
 
Ladies and Gentlemen:
 
    Upon the  terms  and  subject  to conditions  of  the  Exchange  Offer,  the
undersigned  hereby tenders  to the  Company the  aggregate principal  amount of
Existing Notes indicated above. Subject  to, and effective upon, the  acceptance
for  exchange  of the  Existing Notes  tendered  hereby, the  undersigned hereby
sells, assigns and transfers  to, or upon  the order of,  the Exchange Agent  as
agent of the Company all right, title and interest in and to such Existing Notes
as  are  being tendered  hereby, and  irrevocably  constitutes and  appoints the
Exchange Agent as the agent and attorney in fact of the undersigned to cause the
Existing Notes to be transferred and exchanged.
 
    The undersigned hereby represents and warrants that the undersigned has full
power and authority to tender, exchange, sell, assign and transfer the  Existing
Notes tendered hereby and to acquire the New Notes issuable upon the exchange of
such  tendered Existing  Notes, and  that the  Exchange Agent,  as agent  of the
Company, will acquire good and unencumbered title thereto, free and clear of all
liens, restrictions, charges  and encumbrances  and not subject  to any  adverse
claim when the same are accepted by the Exchange Agent, as agent of the Company.
The undersigned will, upon request, execute and deliver any additional documents
deemed  by the  Company or the  Exchange Agent  to be necessary  or desirable to
complete the  sale, exchange,  assignment  and transfer  of the  Existing  Notes
tendered hereby.
 
    The  undersigned also acknowledges that this Exchange Offer is being made in
reliance on  an interpretation  by  the staff  of  the Securities  and  Exchange
Commission  (the  "SEC"), as  set  forth in  no-action  letters issued  to third
parties, that the New Notes issued  in exchange for the Existing Notes  pursuant
to  the  Exchange  Offer  may  be  offered  for  resale,  resold  and  otherwise
transferred  by  holders  thereof  (other  than  any  such  holder  that  is  an
"affiliate"  of the Company within the meaning  of Rule 405 under the Securities
Act or  a broker-dealer  tendering  Existing Notes  acquired directly  from  the
Company  for  its  own account)  without  compliance with  the  registration and
prospectus delivery provisions  of the  Securities Act, provided  that such  New
Notes  are acquired in  the ordinary course  of such holders'  business and such
holders are not engaged in and do not intend to engage in a distribution of  New
Notes and have no arrangement or understanding with any person to participate in
a  distribution of  New Notes.  If the undersigned  is not  a broker-dealer, the
undersigned represents that it is not engaged in, and does not intend to  engage
in, a distribution of New Notes and has no arrangement or understanding with any
person  to participate in a distribution of the New Notes. If the undersigned is
a broker-dealer that will receive New Notes for its own account in exchange  for
Existing  Notes that  were acquired as  a result of  market-making activities or
other trading activities, it acknowledges that  it will deliver a prospectus  in
connection  with any resale of such New  Notes; however, by so acknowledging and
by delivering a prospectus, the undersigned will not be deemed to admit that  it
is an "underwriter" within the meaning of the Securities Act.
 
    By  acceptance of the  Exchange Offer, each  broker-dealer that receives New
Notes pursuant to the Exchange Offer  hereby acknowledges and agrees that,  upon
receipt  of notice by the Company of the  happening of any event which makes any
statement in the Prospectus untrue in any material respect or which requires the
making of any changes in the Prospectus in order to make the statements  therein
not  misleading (which  notice the  Company agrees  to deliver  promptly to such
broker-dealer), such broker-dealer will suspend use of the Prospectus until  the
Company  has amended or supplemented the Prospectus to correct such misstatement
or omission and has furnished copies  of the amended or supplemented  prospectus
to such broker-dealer.
<PAGE>
    The  undersigned represents that (i) such  holder is neither an "affiliate,"
as defined  in  Rule  405  under  the Securities  Act,  of  the  Company  nor  a
broker-dealer  tendering Existing Notes  acquired directly from  the Company for
its account or, if  such holder is  an affiliate, that  such holder will  comply
with the registration and prospectus delivery requirements of the Securities Act
to  the  extent applicable  and  (ii) the  New  Notes acquired  pursuant  to the
Exchange Offer  are being  acquired  in the  ordinary  course of  such  holder's
business.
 
    All  authority  conferred  or  agreed  to be  conferred  in  this  Letter of
Transmittal and every obligation of  the undersigned hereunder shall be  binding
upon   the  successors,  assigns,  heirs,  executors,  administrators,  personal
representatives,  trustees  in  bankruptcy  and  legal  representatives  of  the
undersigned  and  shall not  be affected  by,  and shall  survive, the  death or
incapacity of the undersigned. This tender  may be withdrawn only in  accordance
with  the procedures set forth  in the instructions contained  in this Letter of
Transmittal.
 
    The undersigned understands that tenders  of the Existing Notes pursuant  to
any one of the procedures described under "The Exchange Offer--How to Tender" as
set  forth in the  Prospectus and in  the instructions hereto  will constitute a
binding agreement between the undersigned and the Company in accordance with the
terms and subject to the conditions of the Exchange Offer.
 
    The undersigned  understands that  if its  Existing Notes  are accepted  for
exchange,  such holder will not receive accrued  interest thereon on the date of
exchange. Instead, interest accruing from the most recent date on which interest
has been paid on the  corresponding Existing Note, or,  if no interest has  been
paid,  from January  25, 1996,  will be  payable on  the New  Notes on  the next
scheduled interest payment date.
 
    The undersigned  recognizes that  unless the  holder of  Existing Notes  (i)
completes item (4) of the Box entitled "Description of Existing Notes" above and
(ii)  checks the box entitled  "Check here if tendered  Existing Notes are being
delivered to the Exchange Agent in  exchange for certificated New Notes"  above,
such holder, when tendering such Existing Notes, will be deemed to have tendered
such  Existing Notes in exchange for a  beneficial interest in one or more fully
registered global securities, which will be deposited with, or on behalf of, DTC
and registered in the name of Cede  & Co., its nominee. Beneficial interests  in
such  registered global securities will be  shown on, and transfers thereof will
be effected only through,  records maintained by DTC  and its participants.  See
"Description  of the Notes--Form, Denomination and Book-Entry Procedures" in the
Prospectus.
 
    The undersigned recognizes  that, under certain  circumstances set forth  in
the  Prospectus under "The  Exchange Offer--Conditions," the  Company may not be
required to accept  for exchange any  of the Existing  Notes tendered.  Existing
Notes not accepted for exchange or withdrawn will be returned to the undersigned
at  the  address  set  forth below  unless  otherwise  indicated  under "Special
Delivery Instructions" below.

FORMING PART OF THE TERMS AND CONDITIONS OF THE EXCHANGE OFFER
1. DELIVERY OF THIS LETTER OF TRANSMITTAL AND EXISTING NOTES; GUARANTEED
DELIVERY PROCEDURE
 
    The Letter of Transmittal is to be used to forward, and must accompany,  all
certificates  representing  Existing  Notes tendered  pursuant  to  the Exchange
Offer. Certificates representing the Existing Notes in proper form for  transfer
(or  a  confirmation of  book-entry  transfer of  such  Existing Notes  into the
Exchange Agent's  account at  DTC) as  well  as a  properly completed  and  duly
executed  copy of this Letter of Transmittal and all other documents required by
this Letter  of Transmittal,  must be  received  by the  Exchange Agent  at  its
address  set  forth herein  on  or before  the  Expiration Date.  Existing Notes
tendered hereby must  be in  denominations of  principal amount  of maturity  of
$1,000  and any integral multiple thereof. Partial tenders of Existing Notes may
be made only  if (i)  the principal  amount tendered is  equal to  $1,000 or  an
integral  multiple thereof  and (ii)  the remaining  untendered portion  is in a
principal amount  of $250,000  or  any integral  multiple  of $1,000  in  excess
thereof.
 
    The method of delivery of this Letter of Transmittal, the Existing Notes and
all  other  required documents  is at  the  election and  risk of  the tendering
holders, but the  delivery will be  deemed made only  when actually received  or
confirmed  by the Exchange Agent. 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 permit timely delivery.
 
    If  a holder  desires to  tender Existing  Notes and  such holder's Existing
Notes are not immediately available or time will not permit such holder's Letter
of Transmittal,  Existing Notes  (or a  confirmation of  book-entry transfer  of
Existing  Notes  into the  Exchange Agent's  account at  DTC) or  other required
documents to reach  the Exchange Agent  on or before  the Expiration Date,  such
holders may nevertheless tender Existing Notes, if:
 
          (a)  such tender  is made  by or  through an  Eligible Institution (as
    defined below);
 
          (b)  a  properly completed  and  duly executed  Notice  of  Guaranteed
    Delivery,  in substantially  the form  provided by  APS, is  received by the
    Exchange Agent as provided below on or prior to the Expiration Date; and
 
        (c) the Existing Notes, in proper form for transfer (or confirmation  of
    book-entry transfer of such Existing Notes into the Exchange Agent's account
    at  DTC as  described above),  together with  a properly  completed and duly
    executed Letter  of Transmittal  and  all other  documents required  by  the
    Letter  of Transmittal, are  received by the Exchange  Agent within five New
    York Stock Exchange, Inc. trading days  after the date of execution of  such
    Notice of Guaranteed Delivery.
 
2. WITHDRAWALS
 
    Any  holder  who had  tendered  Existing Notes  may  withdraw the  tender by
delivering written  notice of  withdrawal to  the Exchange  Agent prior  to  the
Expiration  Date.  For  a  withdrawal  to  be  effective,  a  written  notice of
withdrawal must  be received  by the  Exchange Agent  at its  address set  forth
herein.  Any such notice of  withdrawal must (i) specify  the name of the person
having tendered the Existing Notes to  be withdrawn (the "Depositor"), (ii)  (a)
if  the Existing  Notes have  been physically  delivered to  the Exchange Agent,
identify the Existing Notes to be withdrawn (including the serial number and the
principal amount), or (b) if the Existing Notes have been delivered pursuant  to
book-entry  procedures, identify the name and  number of the holder's account at
DTC to be credited with such Existing Notes and (iii) be signed by the holder in
the same manner as the original signature on the Letter of Transmittal by  which
such  Existing Notes were  tendered or as  otherwise set forth  in Instruction 3
below (including  any  required  signature guarantees),  or  be  accompanied  by
documents  of  transfer  sufficient  to  have the  Trustee  (as  defined  in the
Prospectus) register the transfer  of such Existing Notes  into the name of  the
person  withdrawing the tender. If Existing Notes have been tendered pursuant to
the procedure for book-entry transfer, any notice of withdrawal must specify the
name and number of the account at DTC to be credited with the withdrawn Existing
Notes  or   otherwise  comply   with  DTC's   procedures.  See   "The   Exchange
Offer--Withdrawal Rights" in the Prospectus.
<PAGE>
3. SIGNATURES ON THIS LETTER OF TRANSMITTAL; BOND POWERS AND ENDORSEMENTS;
   GUARANTEE OF SIGNATURES
 
        If this Letter of Transmittal  is signed by the registered holder of the
   Existing Notes tendered  hereby, the signature  must correspond exactly  with
   the  name  as written  on the  face  of the  certificates without  any change
   whatsoever.
 
    If any tendered  Existing Notes are  owned of  record by two  or more  joint
owners, all such owners must sign this Letter of Transmittal.
 
    If  any tendered Existing Notes are registered in different names on several
certificates, it will be necessary to complete, sign and submit as many separate
copies of this  Letter of Transmittal  as there are  different registrations  of
certificates.
 
    If  this Letter  of Transmittal  or any  Existing Notes  or bond  powers 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  indicate when signing, and  unless waived by  the
Company,  proper evidence satisfactory  to the Company of  their authority so to
act must be submitted.
 
    The signatures on this Letter of  Transmittal or a notice of withdrawal,  as
the  case may be, must  be guaranteed unless the  Existing Notes surrendered for
exchange pursuant hereto are tendered (i) by a registered holder of the Existing
Notes or (ii) for the account of an Eligible Institution. In the event that  the
signatures  in this Letter of Transmittal or a notice of withdrawal, as the case
may be, are required to  be guaranteed, such guarantees  must be by an  eligible
guarantor  institution  which  is a  member  of The  Securities  Transfer Agents
Medallion Program  (STAMP), The  New York  Stock Exchanges  Medallion  Signature
Program  (MSP) or  The Stock  Exchanges Medallion  Program (SEMP) (collectively,
"Eligible Institutions"). If  Existing Notes  are registered  in the  name of  a
person  other than the signer of this  Letter of Transmittal, the Existing 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   holder  with  the  signature  thereon  guaranteed  by  an  Eligible
Institution.
 
4. BACKUP FEDERAL INCOME TAX WITHHOLDING AND INTERNAL REVENUE SERVICE FORM W-9
 
    Under the federal income tax laws, payments that may be made by the  Company
on  account of New Notes issued pursuant to the Exchange Offer may be subject to
backup  withholding  at  the  rate  of  31%.  In  order  to  avoid  such  backup
withholding, each tendering holder should complete and sign the Internal Revenue
Service  Form W-9 (the "IRS Form W-9")  included with this Letter of Transmittal
and either (a) provide  the correct taxpayer  identification number ("TIN")  and
certify,  under penalties of perjury, that the  TIN provided is correct and that
(i) the holder has not been notified by the Internal Revenue Service (the "IRS")
that the holder  is subject  to backup  withholding as  a result  of failure  to
report  all interest or dividends  or (ii) the IRS  has notified the holder that
the holder  is  no longer  subject  to backup  withholding;  or (b)  provide  an
adequate  basis for exemption. If the tendering holder has not been issued a TIN
and has applied for one,  or intends to apply for  one in the near future,  such
holder should write "Applied For" in the space provided for the TIN in Part 1 of
the IRS Form W-9 and sign and date the IRS Form W-9. If "Applied For" is written
in  Part 1, the Company  (or the Paying Agent  under the Indenture governing the
New Notes) shall retain 31% of payments made to the tendering holder during  the
sixty  (60) day  period following the  date of the  IRS Form W-9.  If the holder
furnishes the Exchange Agent or the Company with its TIN within sixty (60)  days
after  the date  of the IRS  Form W-9, the  Company (or the  Paying Agent) shall
remit such amounts retained during the sixty  (60) day period to the holder  and
no  further amounts  shall be  retained or  withheld from  payments made  to the
holder thereafter. If, however, the holder  has not provided the Exchange  Agent
or  the Company with its TIN within such  sixty (60) day period, the Company (or
the Paying Agent)  shall remit such  previously retained amounts  to the IRS  as
backup  withholding.  In general,  if a  holder is  an individual,  the taxpayer
identification number is the Social Security  number of such individual. If  the
Exchange  Agent or the Company is not  provided with the correct TIN, the holder
may be subject to a $50 penalty imposed by the IRS. Certain holders  (including,
among  others, all corporations and certain foreign individuals) are not subject
to these backup withholding and reporting  requirements. In order for a  foreign
individual  to qualify as  an exempt recipient,  such holder must  submit an IRS
Form W-8,  signed under  penalties of  perjury, attesting  to that  individual's
exempt status. An IRS Form
<PAGE>
W-8  can be obtained from the Exchange Agent. For further information concerning
backup withholding and instructions for  completing the IRS Form W-9  (including
how  to obtain a TIN if you do not have one and how to complete the IRS Form W-9
if Existing Notes are  registered in more than  one name), consult the  enclosed
instructions to the IRS Form W-9.
 
    Failure  to complete the  IRS Form W-9  will not, by  itself, cause Existing
Notes to  be deemed  invalidly tendered,  but may  require the  Company (or  the
Paying  Agent) to withhold 31% of the amount  of any payments made on account of
the New  Notes. Backup  withholding is  not an  additional federal  income  tax.
Rather,  the  federal  income  tax  liability  of  a  person  subject  to backup
withholding will  be reduced  by  the amount  of  tax withheld.  If  withholding
results in an overpayment of taxes, a refund may be obtained from the IRS.
 
5. TRANSFER TAXES
 
    The  Company will pay all transfer taxes, if any, applicable to the transfer
of Existing  Notes to  it  or its  order pursuant  to  the Exchange  Offer.  If,
however,  New Notes  and/or substitute  Existing Notes  not exchanged  are to be
delivered to, or are to be registered or issued in the name of, any person other
than the registered holder of the Existing Notes tendered hereby, or if tendered
Existing Notes are registered in  the name of any  person other than the  person
signing  this Letter  of Transmittal, or  if a  transfer tax is  imposed for any
reason other than the  transfer of Existing  Notes to the  Company or its  order
pursuant  to the Exchange Offer, the amount  of any such transfer taxes (whether
imposed on the registered holder  or any other persons)  will be payable by  the
tendering holder. If satisfactory evidence of payment of such taxes or exemption
therefrom  is not submitted herewith, the amount  of such transfer taxes will be
billed directly to such tendering holder.
 
    Except as  provided in  this Instruction  5, it  will not  be necessary  for
transfer tax stamps to be affixed to the Existing Notes specified in this Letter
of Transmittal.
 
6. WAIVER OF CONDITIONS
 
    The  Company reserves the absolute right to waive satisfaction of any or all
conditions enumerated in the Prospectus.
 
7. NO CONDITIONAL TENDERS
 
    No  alternative,  conditional,  irregular  or  contingent  tenders  will  be
accepted.  All tendering holders of Existing  Notes, by execution of this Letter
of Transmittal, shall  waive any right  to receive notice  of the acceptance  of
their Existing Notes for exchange.
 
    Neither  the Company  nor any  other person is  obligated to  give notice of
defects or  irregularities  in any  tender,  nor shall  any  of them  incur  any
liability for failure to give any such notice.
 
8. INADEQUATE SPACE
 
    If  the space provided herein is  inadequate, the aggregate principal amount
of Existing  Notes being  tendered and  the certificate  number or  numbers  (if
available)  should  be  listed  on  a  separate  schedule  attached  hereto  and
separately signed by all parties required to sign this Letter of Transmittal.
 
9. MUTILATED, LOST, STOLEN OR DESTROYED EXISTING NOTES
 
    Any holder  whose  Existing  Notes  have been  mutilated,  lost,  stolen  or
destroyed  should contact the Exchange Agent  at the address indicated above for
further instructions.
 
10. REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES
 
    Questions relating to the procedure for  tendering, as well as requests  for
additional  copies  of the  Prospectus and  this Letter  of Transmittal,  may be
directed to the  Exchange Agent at  the address and  telephone number  indicated
above.

PART III  CERTIFICATION
- ------------------------------------------------------------------------------------------------------------------------------------
Under penalties of perjury, I certify that:

1. The number shown on this form is my correct taxpayer identification number (or I am waiting for a number to be issued to me), AND

2. I am not subject to backup withholding because: (a) I am exempt from backup withholding, or (b) I have not been notified by the
   Internal Revenue Service that I am subject to backup withholding as a result of a failure to report all interest or dividends, or
   (c) the IRS has notified me that I am no longer subject to backup withholding.

CERTIFICATION INSTRUCTIONS.--You must cross out item 2 above if you have been notified by the IRS that you are currently subject to
backup withholding because of underreporting interest or dividends on your tax return. For real estate transactions, item 2 does not
apply. For mortgage interest paid, the acquisition or abandonment of secured property, cancellation of debt, contributions to an
individual retirement arrangement (IRA), and generally payments other than interest and dividends, you are not required to sign the
Certification, but you must provide your correct TIN. (Also see PART III INSTRUCTIONS on page 2.)

SECTION REFERENCES ARE TO THE INTERNAL REVENUE CODE.
 
PURCHASE OF FORM.--A person who is required to file an information return with
the IRS must get your correct TIN to report income paid to you, real estate
transactions, mortgage interest you paid, the acquisition or abandonment of
secured property, cancellation of debt, or contributions you made to an IRA. Use
Form W-9 to give your correct TIN to the requester (the person requesting your
TIN) and, when applicable, (1) to certify the TIN you are giving is correct (or
you are waiting for a number to be issued), (2) to certify you are not subject
to backup withholding, or (3) to claim exemption from backup withholding if you
are an exempt payee. Giving your correct TIN and making the appropriate
certifications will prevent certain payments from being subject to backup
withholding.
 
NOTE: IF A REQUESTER GIVES YOU A FORM OTHER THAN A W-9 TO REQUEST YOUR TIN, YOU
MUST USE THE REQUESTER'S FORM IF IT IS SUBSTANTIALLY SIMILAR TO THIS FORM W-9.
 
WHAT IS BACKUP WITHHOLDING?--Persons making certain payments to you must
withhold and pay to the IRS 31% of such payments under certain conditions. This
is called "backup withholding." Payments that could be subject to backup
withholding include interest, dividends, broker and barter exchange
transactions, rents, royalties, nonemployee pay, and certain payments from
fishing boat operators. Real estate transactions are not subject to backup
withholding.
 
    If you give the requester your correct TIN, make the proper certifications,
and report all your taxable interest and dividends on your tax return, your
payments will not be subject to backup withholding. Payments you receive will be
subject to backup withholding if:
 
    1. You do not furnish your TIN to the requester, or
 
    2. The IRS tells the requester that you furnished an incorrect TIN, or
 
    3. The IRS tell you that you are subject to backup withholding because you
did not report all your interest and dividends on your tax return (for
reportable interest and dividends only), or
 
    4. You do not certify to the requester that you are not subject to backup
withholding under 3 above (for reportable interest and dividend accounts opened
after 1983 only), or
 
    5. You do not certify your TIN. See the Part III instructions for
exceptions.
 
    Certain payees and payments are exempt from backup withholding and
information reporting. See the Part II instructions and the separate
INSTRUCTIONS FOR THE REQUESTER OF FORM W-9
 
HOW TO GET A TIN.--If you do not have a TIN, apply for one immediately. To
apply, get FORM SS-5, Application for a Social Security Number Card (for
individuals), from your local office of the Social Security Administration, or
FORM SS-4, Application for Employer Identification Number (for businesses and
all other entities), from your local IRS office.
 
    If you do not have a TIN, write "Applied For" in the space for the TIN in
Part I, sign and date the form and give it to the requester. Generally, you will
then have 60 days to get a TIN and give it to the requester. If the requester
does not receive your TIN within 60 days, backup withholding, if applicable,
will begin and continue until you furnish your TIN.

NOTE: WRITING "APPLIED FOR" ON THE FORM MEANS THAT YOU HAVE ALREADY APPLIED FOR
A TIN OR THAT YOU INTEND TO APPLY FOR ONE SOON.
 
    AS SOON AS YOU RECEIVE YOUR TIN, COMPLETE ANOTHER FORM W-9, INCLUDE YOUR
TIN, SIGN AND DATE THE FORM, AND GIVE IT TO THE REQUESTER.
 
PENALTIES
 
FAILURE TO FURNISH TIN.--If you fail to furnish your correct TIN to a requester,
you are subject to a penalty of $50 for each such failure unless your failure is
due to reasonable cause and not to willful neglect.
CIVIL PENALTY FOR FALSE INFORMATION WITH RESPECT TO WITHHOLDING.--If you make a
false statement with no reasonable basis that results in no backup withholding,
you are subject to a $500 penalty.
 
CRIMINAL PENALTY FOR FALSIFYING INFORMATION.--Willfully falsifying
certifications or affirmations may subject you to criminal penalties including
fines and/or imprisonment.
 
MISUSE OF TINS.--If the requester discloses or uses TINs in violation of Federal
law, the requester may be subject to civil and criminal penalties.
 
SPECIFIC INSTRUCTIONS
NAME.--If you are an individual, you must generally enter the name shown on your
social security card. However, if you have changed your last name, for instance,
due to marriage, without informing the Social Security Administration of the
name change, please enter your first name, the last name shown on your social
security card, and your new last name.
 
    SOLE PROPRIETOR.--You must enter your individual name. (Enter either your
SSN or EIN in Part I.) You may also enter your business name or "doing business
as" name on the business name line. Enter your name as shown on your social
security card and business name as it was used to apply for your EIN on Form
SS-4.
 
PART I--TAXPAYER IDENTIFICATION NUMBER (TIN)
 
You must enter your TIN in the appropriate box. If you are a sole proprietor,
you may enter your SSN or EIN. Also see the chart on this page for further
clarification of name and TIN combinations. If you do not have a TIN, follow the
instructions under HOW TO GET A TIN on page 1.
 
PART II--FOR PAYEES EXEMPT FROM BACKUP WITHHOLDING
 
Individuals (including sole proprietors) are not exempt from backup withholding.
Corporations are exempt from backup withholding for certain payments, such as
interest and dividends. For a complete list of exempt payees, see the separate
Instructions for the Requester of Form W-9.
 
    If you are exempt from backup withholding, you should still complete this
form to avoid possible erroneous backup withholding. Enter your correct TIN in
Part I, write "Exempt" in Part II, and sign and date the form. If you are a
nonresident alien or a foreign entity not subject to backup withholding, give
the requester a completed FORM W-8, Certificate of Foreign Status.
 
PART III--CERTIFICATION
 
For a joint account, only the person whose TIN is shown in Part I should sign.
 
    1. INTEREST, DIVIDEND, AND BARTER EXCHANGE ACCOUNTS OPENED BEFORE 1984 AND
BROKER ACCOUNTS CONSIDERED ACTIVE DURING 1983. You must give your correct TIN,
but you do not have to sign the certification.
 
    2. INTEREST, DIVIDEND, BROKER, AND BARTER EXCHANGE ACCOUNTS OPENED AFTER
1983 AND BROKER ACCOUNTS CONSIDERED INACTIVE DURING 1983. You must sign the
certification or backup withholding will apply. If you are subject to backup
withholding and you are merely providing your correct TIN to the requester, you
must cross out item 2 in the certification before signing the form.
 
    3. REAL ESTATE TRANSACTIONS. You must sign the certification. You may cross
out item 2 of the certification.
 
    4. OTHER PAYMENTS. You must give your correct TIN, but you do not have to
sign the certification unless you have been notified of an incorrect TIN. Other
payments include payments made in the course of the requester's trade or
business for rents, royalties, goods (other than bills for merchandise), medical
and health care services, payments to a nonemployee for services (including
attorney and accounting fees), and payments to certain fishing boat crew
members.
 
    5. MORTGAGE INTEREST PAID BY YOU, ACQUISITION OR ABANDONMENT OF SECURED
PROPERTY, CANCELLATION OF DEBT, OR IRA CONTRIBUTIONS. You must give your correct
TIN, but you do not have to sign the certification.
 
PRIVACY ACT NOTICE
 
Section 6109 requires you to give your correct TIN to persons who must file
information returns with the IRS to report interest, dividends, and certain
other income paid to you, mortgage interest you paid, the acquisition or
abandonment of secured property, cancellation of debt, or contributions you made
to an IRA. The IRS uses the numbers for identification purposes and to help
verify the accuracy of your tax return. You must provide your TIN whether or not
you are required to file a tax return. Payers must generally withhold 31% of
taxable interest, dividend, and certain other payments to a payee who does not
give a TIN to a payer. Certain penalties may also apply.
